2 Stroke Reading Rodless Cylinder with rake Incorporating a brake mechanism and stroke sensor allows positioning with high repeatability. (Stopping accuracy ± 0. mm) rake mechanism Employs a combination spring and pneumatic lock type. The cylinder position will be held by spring force when air pressure is absent. rake holder rake spring iaphragm rake shoe Slider rake operating port rake releasing port The brake mechanism gives no direct load on the cylinder. Spring force acts directly on the brake shoes to hold the brake disk; therefore, the table can be stopped without affecting the cylinder performance. Locking in both directions is possible. Locking in either side of cylinder stroke is possible, too. rake shoe rake plate Maintenance and inspection rake unit is replaceable and has a manual override. esides that, manual release is also possible manually. Rodless cylinder variety of piping port locations gives high-freedom on machine design.

4 Series ML efore Operation System Checking low Chart Stroke reading cylinder with brake permits precise positioning at any designated point on its travel with combination of CEU, directional control valve, brake valve. Check the operation flow chart below before starting the operation or stopping positioning repeatability may be compromised. Without guide With guide STRT Is the total of moment to cylinder from each direction and load rate of allowable load less than? (Refer to Model Selection on pages and.) Kinetic energy is under the allowable? (Refer to Model Selection on page.) When the mounting position is located on the horizontal wall, implement a guide regardless of the load factor. Select cylinder size with load rate less than. Select cylinder size so that the kinetic energy is allowable. Model Selection Maximum allowable load and allowable moment will vary depending on workpiece mounting methods, mounting orientation and piston speed. determination of usability is performed based on the operating limit values in the graphs with respect to operating conditions, but the total (Σαn) of the load factors (αn) for each weight and moment should not exceed. esides, if it is used for positioning, maximum speed that can be achieved shall be 00 mm/s or less. or details, refer to either Instruction manual for positioning system with brake (rodless type) or Instruction manual for y-rodless Cylinder. Load Weight Load weight (kg) W Can the positioning be adjusted by the re-try function without oversteps plus side? Is there a problem when setting position oversteps plus side? Isn't that affected by the reaction force or impact force during the positioning motion? ue to fluctuation of speed, etc, Stroke reading cylinder with brake may overrun beyond the set position. t this point, although the re-entry function will automatically work to redress the stop position, there may be the case it cannot be redressed.

Piping Piping length between cylinder ports and solenoid valve for driving should be less than 0 cm. When using system with brake, piping length between solenoid valve for braking and brake supply port should be less than m. If longer, the brake function may be delayed when the cylinder position is held, for emergency stops or cylinder may eject at brake release.. ir balance ir balance on both pneumatic circuits mentioned above is made by supplying air pressure, to both sides of the piston when at intermediate stop. When mounting vertically the balance of load is kept by a regulator () decreases up-stream pressure. Use caution the piston rod may be lurched when the next motion gets started after the intermediate stops or commence the operation after the reverse motion gets done, unless the air balance is taken. It may result in degrading its accuracy.. Supply pressure Set supply pressure 0. to 0. MPa to brake release port. When supply pressure is below 0. MPa brake may not be released, when it is over 0. MPa brake life may be shortened. If line pressure is used directly as supply pressure, any fluctuation in pressure will appear in the form of changes in cylinder characteristics. Therefore, make sure to use a pressure regulator to convert line pressure into supply pressure for the solenoid valve for driving and the solenoid valve for braking. In order to actuate multiple cylinders at once, use a pressure regulator that can handle a large air flow volume and also consider installing an air tank. 0--

7 Stroke Reading Rodless Cylinder with rake Series ML Mounting Using. Position detecting sensor Stroke reading rodless cylinder with brake is a magnetic type sensor. Strong magnetic fields around the sensor will cause a malfunction. External magnetic fields should be less than. mt. magnetic field of. mt is equivalent to a position that has about 8 cm radius from a welded part using about,000 amperes of welding amperage. When using it in a stronger magnetic field, cover the sensor with magnetic and shield it. Welding machine 8 cm 8 cm 8 cm Operating range void applications where the cylinder is in direct contact with water and oil, etc.. Noise When stroke reading hy-rodless cylinder with brake is used in an atmosphere with electrical noise from a motor, welding machine, miscount is created by this noise: To prevent this, the noise source and wiring should be seperated from power wire. Maximum transmitted distance for stroke reading rodless cylinder with brake is 0 m. e sure not to exceed this wire length.. Mounting lush piping thoroughly before connection in order to prevent dust or chips from entering the cylinder. Take care not to score slide surface of the cylinder tube. This may damage the bearing and scraper, resulting in malfunctioning of the cylinder. Take care not to apply a strong impact or excessive moment to the table when loading a workpiece as slide table is supported by bearing made of resin.. Piping Piping connection to head covers can be selected according to application. ottom piping is effective for high density designed equipment and machines since piping does not come out from the mounting surface. (elow fig.: Refer to piping port variation. ). When a stroke reading hy-rodless cylinder with brake is connected to load with an external support mechanism, accurate alignment is required even if the ML can be used with direct load within the allowable range. If stroke is longer, axis alignment deflection will be greater, therefore install floating mechanism to absorb deflection. This actuator can be used without lubricaton. owever, if it is lubricated, use turbine oil Class (ISO VG). (o not use machine oil or spindle oil.). Cover the cylinder when it is used in an environment where cutting dust, powder (paper powder, thread yarn, etc.) and cutting oil (gas oil, water, warm water, etc.). We recommend that grease be regularly applied to bearing (slide part) and dust seal band as it may extend the service life.. rake and scale plate should be protected from load and external force which may cause malfunction. o not apply load and external force on brake and scale plate. Readjustment for brake and scale plate in normal operating condition is not necessary due to preadjustment prior to delivery. Therefore, do not change the setting on adjustment parts carelessly.

Positioning at cylinder stroke end Stable stop accuraccy at end of stroke positioning is not obtained due to large speed change from cushion influence. Therefore, positioning position must not be within cushion stroke. (Refer to cushion stroke table.). System with counter Counter respond speed is generally called counting speed. If cylinder with brake is faster than counting speed in counter, the counter will make a reading error and misscounting occurs. Use CEU, CEU, or CEU. Cylinder speed < Counting speed in counter (Cylinder speed 00 mm/s is equivalent to kcps of counting speed in counter.). Ejection from jumping at beginning of extend or retract stroke may cause temporarily high speeds exceeding the response speed counting speed in the counter or position detection sensor. This can be a cause of malfunction. CEP CE CE ML C G-S R - 0- ata 0--7

Therefore, when normally using the cylinder near the upper limit of the holding force, be aware of the points described below. Select the cylinder bore size so that the load is less than 80% of the holding force. If the piston rod slips because the lock's holding force has been exceeded, the brake shoe could be damaged, resulting in a reduced holding force or shortened life.

11 Stroke Reading Rodless Cylinder with rake Series ML Cushion Capacity Cushion Selection <ir cushion> Stroke reading hy-rodless cylinder with brake is equipped with a standard air cushion. The air cushion mechanism is incorporated to prevent excessive impact of the piston at the stroke end during high speed operation. The purpose of air cushion, thus, is not to decelerate the piston near the stroke end. The weight and speed ranges that the air cushion can absorb are shown within the limit lines on the graph. <Stroke adjusting unit with shock absorber> Use this unit to decelerate the cylinder when weight and speed are beyond the air cushion limit lines or when the stroke adjustment causes limited or no cushion engagement. Caution. The absorption capacity of each unit shown here is given for the mounted shock absorber when used at full stroke. When the effective stroke of the absorber decreases as a result of stroke adjustment, the absorption capacity becomes extremely small. ix the adjusting bolt to around 0. mm projection from the shock absorber as shown below. djusting bolt Shock absorber 0..
