How to Conduct Piping

Strictly, MINIDEX performs indexaction by double motion. As shown

in right figure, movement byapproximately 5 is required toconduct locking. It is necessary totake this into consideration. Thetorque at locking is always largerthan that at indexing.

!Piping for index should beconducted to direction of two bandwires on the body. (for only MD50and 75)

Allowable Load and Index Time

Model Indication

1.Since MINIDEX is small, even if production accuracy isretained within 0.02, angle error becomes 8 (in thecase of MD-30.) Index accuracy more than it cannot beinsured. Therefore, it is not recommended to design so asto obtain index accuracy in second directly from the shaft.In this case, the way to insert positioning pin into drivenunit should be adopted.

2.Mechanically, MINIDEX moves almost uniformly.

Therefore, applying excessive load or high-speedoperation with large load is not recommended. Indesigning, try to extremely minimize GD2 (inertia).

3.Products complied with the standard are used for innerseals. Abrasion or damage of the seals may cause airleakage and result in output descent. For exchange ofseals, contact us.

4.Installation altitude is free from limit, however, the way ofuse that load is applied to shaft (thrust) is notrecommended.Thrust load should be received outside by thrust

bearing.5.See Instruction Manual for Safety and Handling

before using.

Mechanical Multipoint Stop Unit

CONTENTS

[MULTISTOPPER] is epoch-making product that make it possible for variousfeed equipment to perform intermediate multipoint stop.

In feeding of slide table by air cylinder, for instance, stopping can be made at only two points; forwardand backward end of cylinder. In the case where the table is required to be stopped accurately at mid-

position, the way to set movable stopper is adopted in many cases. However, in the case where manypoints, such as 4 or 5 points, mechanism and control become complex. MULTISTOPPER is useful insuch a case.

What is MULTISTOPPER ?

Application Example

7

MULTISTOPPER, being application product of small pneumatic intermittent cylinder MINIDEX made by us, isprovided with the turntable on which many stopper pins are mounted on the end face of the disc, intermittently turnsthe disc each time when slide jigs make reciprocating, switches to stopper pins different in length and applies them toslide jigs, and make stopping and positioning mechanically at many points. The figure below shows an example ofapplication ; the equipment to distribute to different 6 points by catching works supplied in turn to given place by

parts feeder ( or conveyer ). Stopping can be made mechanically and accurately without using expensive pulse

motor or servo system. Dealing with preparation of works of different types can be simply made by changing eachdisc or pins (Special Specification). Rotation control of main body can be conducted by only 1 four way valve, and 2pipes are sufficient for piping. Follow to the figure below.

There are many successful applications of MULTISTOPPER. The photographs below show examples ofapplication. Another application is that general purpose spot welding machine, which is provided with MINIDEXequipped with reduction gear on the shaft, mounted with 24 stopper pins on disc and installed as XY moving jig, isused as special purpose machine capable of applying spot welding continuously to more than 50 point.

3. In setting pin length, determine from thrust load with reference to the figure below. ( Pin material is set to thatequivalent to S45C. )

1.Control of MULTISTOPPER itself is performed by the limit switch to turn the four way valve and the valve to ON/OFF or by theO

timer. In the case of division into 4, for instance, when the valve is turned to ON, it stops after rotating approximately 85 .Therefore, the signal is necessary at that point, and when the valve is turned to OFF by this signal, it is locked after rotating

O Oremaining 5 . Moreover, the original position signal is obtained at the point of a total of 90 (1 index ), which is used asforward signal for table, etc. Two each of LS are necessary. ( In the case of timer control, LS is not required, or l each isrequired at original position. )

2.For verification of contact of stopper pin and reinforcing plate, the figure below shows one of methods having been performedfor reference.

3.If verification of contact mentioned above is performed, it is not objectionable to omit verification of position of each stopper.However, if necessary, detection by setting multiple dog in near shaft should be performed. In the case of division into 8, forinstance, signals at each position can be found by combination of 3 or 4 each of LS. ( More than 20 signals were obtained by

Ocombination of 5 each of LS in the example shown in the photo of previous item. ) Since lock angle is 5 being small, smallsensors should be used.

Note : Another 1 each of LS is necessary for the original position of stopper.

4.In the case of high speed movement by air cylinder, shock is generated at stop end. In this case, it is preferable to hollow thereinforcing plate, set a shaft and install a small shock absorber in its back.

Note for Installing

1. Install stopper pins and reinforcing plate so that lean is not generated at the time of impacting. If torque is

generated on stopper disc at the time of impacting, the main body may be damaged.2. When stopper pins are mounted and locked, pay attention not to apply torque to the disc. Make sure to fix

the disc by vice, etc, or insert a bar into the detent hole around the periphery of the disc, and fasten the locknut. ( Care should be taken strictly when assembling. )

3. Thrust load is supported by metal bearing. Oil sometimes.4. Try to rotate as slowly as possible so as not to generate impact at the time of indexing and locking.

! Four-way or five-way valve ( single or double deflection, orhand valve ) should be used.

!Air port at rotating table side (upper side) is for indexing, andthat at lower side for locking. Indexing is performed bysupplying air alternately to two air ports. (One reciprocating ofinternal piston shows 1 index.)

! When air is supplied to index side, stopping is made at 5 -

7shorter than required index angle. Then, when air issupplied to lock side, locking is made while rotating remaining5 7.

! Trial run should be started at lower speed (speed control atlower side should be throttled. ), then speed should beincreased gradually. If it is started at high speed first, internalcam may be damaged.

! Due to uniform rotation, in the case of high speed, impact isgenerated at stop end. If speed is increased gradually byabove-mentioned method and the table is free of shake,operation can be conducted almost in safety. However, it isrequired to use as slowly as possible within given cycle.

! In the case of built-in to automatic machine, control is madeby timer or limit switch. LS dog should be set at shaft end atlower portion of the table or table side.

! In the case of transverse installation (shaft is level.), loadbalanced right and left against the center of rotation shouldbe applied surely. In the case of single load of arm, etc,advance run to rotation direction or damage of anti-reverse

clutch may occur.! In the case of transverse installation, loading weight is

reduced by half. The main causes of failure are damage ofcam by overload and cutting of parallel pin. In this case,operation is impossible. If you give us information on thestate, we immediately take a necessary action.

! Sub-table should be made to be smaller in diameter andlighter in weight. ( Aluminum, etc )

Note for safety Maintenance and Check Warranty

!Don't touch rotating sectionduring operation to preventdangerous accident.

! It is required to work out designstressed on safety like that air orpower is immediately shut off inthe case of emergency.

!Make sure to verify power andpressure off before installationand removal.

!Operating pressure should be lessthan 0.7Mpa ( 7 kgf/cm )

!Make sure to verify all controlsbefore operation.! In air piping, see the instructions

carefully for correct piping.!Damage, abnormal stress and

insertion to pipe should beavoided.

!Speed control must be surelypiped near the main body withmeter-out.

!Make sure to perform flashing inpipes before piping.!Don't apply load more than

allowance.! In installing load, make sure to

verify that the key shaft is freefrom rattle , and to thrust by setbolts.

Corrective Action for Trouble!In the case where power goes off

or dangerous si tuation isexpected, make sure to turncircuit power to off.

! It should be noted that stoppage isnot conducted immediately evenif emergency stop is made.

!Be away from the machine whenre-operating.

! In the case where troubles arecaused by overload or impact,contact us.

Maintenance and Check!Safety storage method should be

taken.!Following locations are not

suitable for storage of machine oraccessories not in use. Locationwhere ;Children can reach to orcarry out easily, temperature orhumidity change suddenly,humidity is high, volatile matteris stored.

!Disassembly, modification, etcshould not be performed.

!When installing and removing,make sure to shut off air toexhaust residual pressure beforeoperating.

!Although parts complied with thestandard are used for internalseals, abrasion or damage of sealscause air leakage and result inoutput decline. To preventsecondary accident by failure, itis recommended to replace inalmost 5 years, even if they areused in ordinary circumstance.
