8 WM 00PE Product Ejection System Installation and Electrical Connections Prior to installation, check intended location and surrounding area for any potential hazards during operation. All electrical, pneumatic, gas and hydraulic connections, and installation of all system components may only be carried out by qualified personnel. Observe installation instructions for components and accessories. Equipment must be properly grounded and fused according to the rated current consumption (see ID plate). Cables which run outside the system must regularly be checked for wear or damage. Power supply wire gauge and insulation must be sufficient to handle rated current consumption. Cables must never be squeezed or pinched. Do not locate cables or hoses in high traffic areas. Check liquid adhesive feed hoses, screwed connections, and compressed air lines regularly for leaks. These are to be replaced at the first signs of cracks, brittleness etc. Release system pressure completely beforehand. WARNING: Failure to install the system properly, and especially failure to ensure electrical, pressurized, and high pressure feed connections are made correctly, may result in serious injury or death.

9 WM 00PE Product Ejection System 5 Operation The system should only be operated when it is in working order. It should only by operated by qualified persons following all regulations valid for liquid adhesive systems. Never allow the system to be operated by personnel under the influence of substances which reduce their reaction times, or who are not able to operate the equipment for physical reasons. Prior to each startup of the system, check protection and warning devices and make sure they are fully functional. Do not operate the equipment if these devices are not functioning properly. When the removal of safety equipment is required for installation, maintenance, or repair, it must be reconnected immediately upon completion of the work. In a humid environment, only equipment featuring a corresponding class of protection may be operated. Do not operate the system in an explosive environment. Keep parts of the body and clothing away from rotating parts. Do not wear loose articles of clothing when operating or servicing equipment with rotating parts. Remove wrist watches, rings, necklaces or similar jewelry and pin up or cover long hair before performing any work on or with the equipment. The wearing of protective gloves may prove hazardous in certain circumstances where rotating parts are present and may therefore be forbidden. To carry out measurements on the substrate or system components, switch off parent machine and/or system and wait until the equipment comes to a standstill. Never point guns or applicator nozzles at yourself or other persons.

10 WM 00PE Product Ejection System Less-Obvious Dangers WARNING: An operator or service technician working with the equipment should be aware of the less-obvious dangers that often cannot be completely minimized at production sites: Pressurized system components The possibility that electrical potentials may remain in the system after the system was de-energized Liquid adhesive vapors Hydraulically or pneumatically operated system components Uncovered winding parts Action in the Event of System Malfunction If the system malfunctions, switch it off immediately. Turn the main switch off, or use emergency stop switch or similar safety feature as provided. After equipment has come to a standstill and before reoperating it, have it repaired by qualified personnel.

11 WM 00PE Product Ejection System 7 Maintenance/Repair Allow only qualified personnel to perform the procedures described in this document. Work should only be carried out on a completely depressurized system, following all safety procedures. NOTE: Depending on the configuration of the liquid adhesive application system, high pressure may remain between application head(s) and pressure regulator or pump/s even after the system has been switched off using the main switch or the emergency stop. This especially applies to multi-hose configurations between pump/s and application head/s. Prior to maintenance and repair work it is therefore essential to ensure that all liquid adhesive application system components are depressurized as follows:. Release input pressure in front of pump by shutting off customer compressed air supply.. Release any remaining system pressure behind the pumps by manually operating the application heads. Secure pneumatically-and hydraulically-operated equipment against uncontrolled movement. Switch off system electrically. WARNING: Some voltage is still present in the control cabinet even after equipment has been turned off at the main switch. Complete the following steps prior to maintenance or repair:. Disconnect external power supply.. Lock out external power supply.. Check no voltage is present.. Ground and short. 5. Cover nearby live sections. If liquid adhesive application system is left idle for extended periods (e.g. overnight or long breaks) Nordson recommends applying Vaseline to the application head nozzles to prevent them from drying out and becoming blocked as a result. Only use genuine Nordson parts.

12 8 WM 00PE Product Ejection System Cleaning NOTE: Always refer to the liquid adhesive manufacturer s Material Safety Data Sheet or material information sheet before working with any cleaning fluids. WARNING: Never clean any aluminium part or flush any system using halogenated hydrocarbon fluids. Examples of common halogenated hydrocarbons are: dichloromethylene,,,-trichloroethylene, and perchlorethylene. Halogenated hydrocarbons may react violently with aluminium parts. Never use an open flame to clean the system or its components. Check that (warm) water can be used to clean the liquid adhesive system components, possibly with the addition of household washing-up liquid. If this is not possible, use only the cleaning fluid stated in the liquid adhesive manufacturer s information. If the manufacturer recommends heating the cleaner, note the flash point. Ensure sufficient room ventilation to draw off vapors. WARNING: Fire, open flames and smoking are prohibited when cleaning fluids are used. Observe all explosion prevention regulations. Cleaning fluids may only be heated using temperature controlled and explosion-protected heaters. Disposal must be according to the waste key in the DIN Safety Data Sheet. Liquid adhesives or residue, solvent, or separating agents must not be released into open waterways. In the case of a leak or spillage, contain liquid and if necessary use an absorbant material (e.g., sawdust) to soak it up; then proceed according to the relevant waste disposal regulations. If the liquid adhesive application system is to be idle for an extended period, the entire system should be flushed and outlets sealed with Vaseline. Warm water is usually used to flush application systems with which water based liquid adhesives are processed. If the liquid adhesive manufacturer specially recommends a flushing agent, the manufacturer s safety and disposal details must be followed.

13 WM 00PE Product Ejection System 9 Liquid Adhesives As there is a wide variety of liquid adhesives available with different compositions and characteristics, it is impossible here to give an exhaustive list of safety notes reflecting the typical characteristics of liquid adhesives. The use of liquid adhesives in Nordson s liquid adhesive application systems therefore requires reference to the liquid adhesive manufacturer s documents beforehand. Information relating to safety aspects e.g. concerning solvent content, hazards and countermeasures in the event of liquid adhesive coming into contact with skin or mucous membranes are contained in the technical data sheets and the DIN Safety Data Sheets from the manufacturer. Always refer to the manufacturer s Material Safety Data Sheet or material information before working with any liquid adhesives. It may be necessary to refer to the manufacturer s notes on the use of materials from a third party. These may be required for processing a liquid adhesive, but hazards arising from their use are not necessarily mentioned by the manufacturer of the liquid adhesive. Liquid adhesives may still give off vapors when they are processed correctly. The smell produced can cause some annoyance. This is especially true where liquid adhesives are used that contain solvent, thus requiring the use of breathing equipment (e.g., a filter). If the prescribed processing conditions are not followed, harmful decomposition products may develop. Therefore, the vapors must be removed. Wash hands well before breaks and when work is finished. If liquid adhesive comes into contact with eyes or mucous membranes, rinse well with water especially the eyes. Change damp clothes, and seek medical advice if it is swallowed. Disposal must be according to the waste key in the DIN Safety Data Sheet. Liquid adhesives or residue, solvent, or separating agents must not be released into open waterways. In the case of a leak or spillage, contain liquid and if necessary use an absorbant material (e.g., sawdust) to soak it up; then proceed according to the relevant waste disposal regulations. If solvents or separating agents are used to process a liquid adhesive, follow the safety and disposal information from the manufacturer.

14 0 WM 00PE Product Ejection System. Description The Nordson WM 00PE product ejection system is a component of a liquid adhesive (cold glue) system. After a product is glued, a detection system determines whether the glue was properly applied. If the glue was not properly applied, the detection system signals the product ejection system to eject the product from the production line. By using the product ejection system, you can ensure that only properly glued products stay on your production line. Figure shows the major components of the product ejection system A Fig. Product Ejection System Components. Motor 5. Guide wheel. Motor control box. Disk. Mounting clamp 7. Solenoid valve. Clamp wheel Functional Description The product ejector is mounted on the transfer section of a folder-gluer machine, just ahead of where the products enter the compression section. The ejector has two wheels: a clamp wheel and a guide wheel. Normally, the clamp wheel is raised and the guide wheel rests on the disk. When the ejector receives a signal to eject a product, the clamp wheel lowers to press the product against the disk and feed it under the guide wheel. The guide wheel then ejects the product from the production line. The clamp wheel raises after the product is ejected.

16 WM 00PE Product Ejection System. Installation Use these procedures to install the product ejection system. Unpacking The product ejection system is shipped fully assembled. Exercise normal care to prevent equipment damage during unpacking. After unpacking the equipment, inspect it for any damage that may have occurred during shipping. Look for dents and scratches and make sure all fasteners are tight. Report any damage to your Nordson representative. Mounting the Product Ejector Follow this procedure to mount the product ejector.. Make sure you have the following customer-supplied items: customized bracketry and a 5 mm ( in.) diameter mounting rod wiring to connect the solenoid valve to the detection system air line tubing to connect the air pressure regulator/filter to an air supply wiring to connect the motor control box to a power supply an electrical disconnect with lock-out capability. Use appropriate bracketry and a 5 mm ( in.) diameter mounting rod to mount the product ejector on the folder-gluer. Make sure the completed installation meets the following requirements: Mount the ejector on the transfer section of the folder-gluer, just ahead of where the products enter the compression section. Use the procedures in the next section, Optional Product Ejector Configurations, as needed to adjust the mounting of the product ejector to accommodate your installation. NOTE: The product ejector can be mounted on either the right- or left-hand side of the production line. For left-hand mounting, the ejector must be partially disassembled and reconfigured, and the motor s direction of rotation must be reversed. The motor can also be switched from the right side to the left side. Figures and show examples of right- and left-hand mounting configurations with the motor on either the right- or left-hand side of the ejector.

18 WM 00PE Product Ejection System Mounting the Product Ejector (contd) Position the ejector as close as possible to the carrier belts on the folder-gluer to maximize the amount of product that passes between the disk and the clamp wheel. You may need to adjust the belts to increase the amount of product that protrudes beyond them. Position the ejector so the disk is parallel to and just below the products. See Figure 5. Position the ejector so the clamp wheel is at an angle of 5 0 to the direction of product travel. Make sure ejected products will follow an unobstructed path away from the folder-gluer. 5 0 Fig. 5 Clamp Wheel Angle A

19 WM 00PE Product Ejection System 5. Set the height of the clamp wheel by loosening the two screws that hold the cylinder bracket to the clamp wheel arm holder and moving the entire clamp wheel assembly to the correct height. The clamp wheel should be as close as possible to the products without touching them as they move between the wheel and the disk.. See Figure. If necessary, adjust the angle of the guide wheel by loosening the center-post nut. The guide wheel must be far enough away from the products so they never contact it unless the clamp wheel has been activated. It is best to start with the guide wheel at a 0 angle to the clamp wheel. The guide wheel angle can be adjusted as needed to change the direction in which products are ejected Fig. Adjusting the Guide Wheel Angle. Guide wheel. Center-post nut

20 WM 00PE Product Ejection System Making the Electrical Connections Follow this procedure to connect a power supply and the motor to the motor control box.. Mount the motor control box as close to the product ejector as possible so it is easily accessible to the operator.. See Figure 7. Route mm (8 AWG) or larger wire from your power supply through the strain relief () on the motor control box and connect the wiring to to terminals L, N, and PE. NOTE: Nordson Corporation recommends that you wire the product ejection system into the folder-gluer run-circuit so the ejector is not powered unless the folder-gluer is running. This will extend the life of the ejector as well as provide safer operation.. Connect the motor control box cable () to the power cable from the motor.

21 WM 00PE Product Ejection System 7 Making the Solenoid Valve Connections Follow this procedure to connect the product ejector solenoid valve to the detection system and to an air supply.. Connect the solenoid valve to the detection system. NOTE: If you have a WM 500 detection system with a VDC marking-output plug, you can connect the solenoid valve directly to the WM 500 using cable 7. For all other WM 500 detection systems, connect the valve to the VDC cast-out outputs of the WM 00AL alarm box.. Connect an air supply line from a non-oiled compressed air supply to the air pressure regulator/filter from the installation kit.. Connect an air supply line from the air pressure regulator/filter to the solenoid valve air input port.. Set the air pressure to the solenoid valve at. bar (0 psi). Setting the WM 500 Unit To use the WM 500 unit s cast-out output to trigger the product ejection system, you must program an alarm-point setting and a marking-length setting into the WM 500 unit. Refer to the WM 500 unit manual for information on how to program these settings. Follow this procedure to determine the alarm-point and marking-length settings. NOTE: If you are not using a WM 500 detection system, refer to the manual for your detection system. Alarm-Point Setting The alarm-point setting is the distance, expressed in meters, from the adhesive sensor s photocell to the point at which the clamp wheel will touch the product. Determine this distance by measuring with a tape measure. Use this number as the initial alarm-point setting. You will make further adjustments to the alarm-point setting later in the Making the Final Adjustments procedure.

22 8 WM 00PE Product Ejection System Marking-Length Setting The marking-length setting controls the length of time the product ejector solenoid valve is energized. This setting is programmed into the WM 500 in meters. Because the ejector takes approximately 0 ms from the time the solenoid valve is energized until the clamp wheel contacts a product, there is a minimum marking-length distance for any given line speed. If the marking-length setting is less than this minimum, the clamp wheel may not move all the way to the product before it begins moving back to its at-rest position. Follow this procedure to determine the marking-length setting.. Determine the most common line speed you will be using; then determine the distance the line travels in 0 ms as follows: If you measure your line speed in feet per minute, multiply the line speed by This will give you the distance (in meters) the line travels at that speed in 0 ms. This is the minimum marking-length setting (MML) for that line speed. Formula: MML = line speed in ft/min x If you measure your line speed in meters per minute, multiply the line speed by This will give you the distance (in meters) the line travels at that speed in 0 ms. This is the minimum marking-length setting (MML) for that line speed. Formula: MML = line speed in m/min x Add / of the product s length in meters to the minimum marking length you calculated in the previous step and use this number as the initial marking-length setting (IML). You will make further adjustments to the marking-length setting in the next procedure, Making the Final Adjustments. Formula: IML = MML + product length in meters Making the Final Adjustments Follow this procedure to make the final adjustments to your installed product ejection system.. Start the production line and run it at your production speed.. Intentionally create some defective products to test the product ejector s response. For example, turn off a gun or block the flow of adhesive from a nozzle with a piece of paper. If adhesive is being applied with a wheel pot, cut a 5 mm ( in.) long gap in the flap of the product to be glued. If possible, run only one or two products at a time during this final adjustment process.

23 WM 00PE Product Ejection System 9. Adjust the alarm-point setting until the product ejector ejects the desired product. Look at the product to see where on the product the clamp wheel is making contact. Adjust the alarm-point setting until the clamp wheel is contacting the product within the first / of its length.. Adjust the marking-length setting until the products are ejected cleanly. If the marking-length setting is too short, the products may not be pulled completely from the carrier belts. If the marking-length setting is too long, the products will eject parallel to the folder-gluer. Correctly setting the marking length is especially important for larger products. 5. Make any other necessary adjustments. You can adjust the variables shown in Table. Variable Alarm-point setting Guide wheel angle Clamp wheel angle Air pressure Table Product Ejection System Adjustments Reason for Adjusting Adjust this setting to change the location where the clamp wheel first makes contact on the product. This will influence the direction and rotation of the product as it is ejected. The angle of the guide wheel determines the path the product takes after it leaves the ejector. If the angle is too large, products will not feed into the guide wheel consistently. This angle is limited by the width of the product passing between the disk and the clamp wheel. A larger angle will give cleaner ejection with less risk of the ejector skewing the product in front of or behind it. The minimum air pressure is.8 bar (0 psi). Higher air pressure will give the clamp wheel a more positive grip on the products. Too much air pressure combined with an excessive marking-length setting can make the clamp wheel overpower the guide wheel, causing products to eject parallel to the folder-gluer.

24 0 WM 00PE Product Ejection System.
