8 Rotary Table Air Consumption Air consumption is the volume of air which is expended by the rotary table's reciprocal operation inside the actuator and in the piping between the actuator and the switching valve, etc. This is necessary for selection of a compressor and for calculation of its running cost. The air consumption (QCR) required for one reciprocation of the rotary table alone is shown in the table below, and can be used to simplify the calculation. Formulas P QCR = 2V x x - ³ 0.13 P QCP = 2 x a x l x x ⁶ QC = QCR + QCP QCR = Air consumption of rotary table [l (ANR)] QCP = Air consumption of tubing or piping [l (ANR)] V = Internal volume of rotary table [cm ₃ ] P = Operating pressure [MPa] l = Length of piping [mm] a = Internal cross section of piping [mm² ] QC = Air consumption required for one reciprocation of rotary table [l (ANR)] When selecting a compressor, it is necessary to choose one which has sufficient reserve for the total air consumption of all pneumatic actuators downstream. This is affected by factors such as leakage in piping, consumption by drain valves and pilot valves, etc., and reduction of air volume due to drops in temperature.

22 Series MSQ Rotary Table Precautions Be sure to read before handling. Design Warning 1. In case of load variations, lifting/lowering operations or changes in frictional resistance, employ a safety design which allows for these factors. Increases in operating speed can cause human injury as well as damage to equipment and machinery. 2. A protective cover is recommended to minimize the risk of human injury. If a stationary object and moving parts of a cylinder are in close proximity, human injury may occur. Design the structure to avoid contact with the human body. 3. Make secure connections so that stationary parts and connecting parts do not become loose. Particularly when operation frequency is high or a rotary actuator is used in a location with excessive vibration, employ a secure method of connection. 4. A deceleration circuit or shock absorber may be required. When a driven object is operated at high speed or the load is heavy, the rotary actuator's cushion may not be able to absorb the impact. Therefore, install a deceleration circuit before the cushion or an external shock absorber to relieve the impact. In this case, the rigidity of the machinery should also be examined.. Consider a possible drop in operating pressure due to a power outage, etc. When a cylinder is used in a clamping mechanism, there is a danger of work pieces dropping if there is a decrease in clamping force due to a drop in circuit pressure caused by a power outage, etc. Therefore, safety equipment should be installed to prevent damage to machinery and/or human injury.. Consider a possible loss of power source. Measures should be taken to protect against human injury and equipment damage in the event that there is a loss of power to equipment controlled by air pressure, electricity or hydraulics, etc. 7. When a speed controller is mounted on an exhaust throttle, employ a safety design which considers residual pressure. If the air supply side is pressurized when there is no residual pressure on the exhaust side, operation will be abnormally fast and this can cause human injury as well as damage to equipment and machinery. 8. Consider emergency stops. Design so that human injury and/or damage to machinery and equipment will not be caused by operation of a rotary actuator when machinery is stopped by a manual emergency stop or by a safety device under abnormal conditions, such as a power outage.. Consider the action when operation is restarted after an emergency stop or abnormal stop. Design the machinery so that human injury or equipment damage will not occur upon restart of operation. When the rotary actuator has to be reset at the starting position, install safe manual control equipment. Design Warning. Do not use the product as a shock absorbing mechanism. If abnormal pressure or leakage occurs, there may be a drastic loss of deceleration effectiveness, leading to a danger of human injury as well as damage to equipment and machinery. Warning Selection 1. Keep the speed setting within the product's allowable energy value. Operation with the kinetic energy of the load exceeding the allowable value can cause damage to the product, leading to human injury as well as damage to equipment and machinery. 2. Provide a shock absorbing mechanism when kinetic energy applied to the product exceeds the allowable value. Operation exceeding the allowable kinetic energy can cause damage to the product and lead to human injury and damage to equipment and machinery. 3. Do not perform stops or holding operations by containing air pressure inside the product. If intermediate stops are performed by containing air with a directional control valve when the product does not have an external stopping mechanism, the stopping position may not be held due to leakage, etc. This can cause human injury and damage to equipment and machinery. Caution 1. Do not operate the product at low speeds which are below the prescribed speed adjustment range. If operated at low speeds below the speed adjustment range, this may cause sticking and slipping or stopping of operation. 2. Do not apply external torque which exceeds the product's rated output. If external force is applied which exceeds the product's rated output, the product can be damaged. 3. Rotation end holding torque for double piston type With double piston type products, if the internal piston is stopped by contact with the angle adjustment screw or cover, the holding torque at the rotation end is half the value of effective output. 4. When repeatability of the rotation angle is required, the load should be directly stopped externally. The initial rotation angle may vary even in products equipped with angle adjustment.. Avoid operation with oil hydraulics. Operation with oil hydraulics can cause damage to the product

23 Warning 1. When angle adjustment is performed while applying pressure, make advance preparations to keep equipment from rotating any more than necessary. When adjustment is performed with pressure applied, there is a possibility of rotation and dropping during adjustment depending on the mounting position of the equipment, etc. This can cause human injury and damage to equipment and machinery. 2. Do not loosen the angle adjustment screw above the adjustment range. If the angle adjustment screw is loosened above the adjustment range, it may come out causing human injury and damage to equipment and machinery. 3. Do not allow external magnetism close to the product. Since the auto switches used are types sensitive to magnetism, external magnetism in close proximity to the product can cause malfunction leading to human injury and damage to equipment and machinery. 4. Do not perform additional machining on the product. Additional machining of the product can result in insufficient strength and cause damage to the product leading to human injury and damage to equipment and machinery.. Do not enlarge the fixed throttle on the piping port by reworking, etc. If the bore is enlarged, rotation speed and impact force will increase, which can cause damage to the product leading to human injury and damage to equipment and machinery.. When using a shaft coupling, use one with a sufficient degree of freedom. If a shaft coupling is used which does not have a sufficient degree of freedom, twisting will occur due to eccentricity, and this can cause malfunction and product damage leading to human injury and damage to equipment and machinery. 7. Do not apply loads to the rotary table exceeding the values shown on features page 4. If loads exceeding the allowable values are applied to the product, this can cause malfunction and product damage leading to human injury and damage to equipment and machinery. Mounting Precautions when using external stoppers When the kinetic energy generated by the load exceeds the limit value of the actuator, an external shock absorbing mechanism must be provided to absorb the energy. The correct method for mounting external stoppers is explained in the figure below. Caution

24 Series MSQ Rotary Table Precautions Be sure to read before handling. Caution Rotation Adjustment 1. As a standard feature, the rotary table is quipped with a rotation adjustment screw (adjustment bolt or shock absorber) that can be used to adjust the rotation. The table below shows rotation adjustment per single rotation of the rotation adjustment screw. With adjustment bolt, With internal shock absorber Series MSQ is equipped with a rubber bumper or shock absorber. Therefore, perform rotation adjustment in the pressurized condition (minimum operating pressure: 0.1MPa or more for adjustment bolt and internal shock absorber types, and 0.2MPa or more for external shock absorber type). Shock Absorber Caution 1. Refer to the table below for tightening torques of the shock absorber setting nut. Tightening torque Rotation adjustment per single rotation of rotation adjustment screw With external shock absorber Rotation adjustment per single rotation of rotation adjustment screw The rotation adjustment range for the external shock absorber is ± at each rotation end. When adjusted beyond this range, note that the shock absorber's durability may decrease Shock absorbers are consumable parts. When a decrease in energy absorption capacity is noticed, it must be replaced. With internal shock absorber 0 0 With external shock absorber Type For low energy For high energy For low energy For high energy For low energy For high energy For low energy For high energy Caution Shock absorber model RBA080-X2 RBA0-X2 RBA1411-X2 RBA1-X821 RBA272-X821 Shock absorber model RB080 RB080 RB0 RB07 RB0 RB07 RB1411 RB14 External Shock Absorber The threaded orifices shown below are not connecting ports. Never remove the plugs as this will cause malfunction. Threaded orifices Shock Absorber 2. Never rotate the bottom screw of the shock absorber. (It is not an adjustment screw.) This may cause oil leakage. 3. When rotation of the rotary table with internal shock absorber is set at a value smaller than the values below, the piston stroke becomes smaller than the shock absorber's effective stroke and energy absorption capacity decreases. Minimum rotation without energy absorption capacity decrease
