46 and 47 are limit switches for detecting the position of the gripping portion 31 of the gripping device 29.

"Operation of the embodiment of the present invention" In the above structure, when the rod 18 of the air cylinder 16 is protruded from the state shown in FIG. , the limit switch 44 is activated and stops the movement of the rod 18. Therefore, the support stand 5 also stops at this position.

Therefore, the collection chuck 19 is in a state of protruding from the through hole 2 of the base plate 1.

Thereafter, the collect chuck actuator 32 is activated. That is, the air cylinder 43 is actuated to lower the rod 42, and the pair of arms 40, 40 are moved via the link ball 41 around the shaft 39 rotatably attached to the support 38, as shown by the imaginary line in FIG. Rotate it to the position shown.

Therefore, the sliding member 36 descends against the elastic force of the spring 37, and automatically moves the upper part of the collect chuck 19 in the diametrical direction by the elastic force provided in advance at the upper part of the collect chuck 19. open.

Note that even if the automatic loading device operates with a lipstick container etc. clamped in the concave portion 24 of the collection chuck 19 and clamps the other lipstick container etc., the clamping of the collection chuck is released. good.

In this state, an automatic loading device (not shown) or the like automatically takes out a lipstick container, etc. from the recess 24 of the collection chuck 19, and inserts another lipstick container, etc. to be measured into the recess 24. insert.

Thereafter, the collect chuck actuating device 32 is activated. That is, the air cylinder 43 is actuated to raise the rod 42, and the pair of arms 40, 40 are moved around the shaft 39 rotatably attached to the support 38 via the link ball 41, as indicated by the solid line in FIG. Rotate it to the position shown.

Therefore, the sliding member 36 has a pair of arms 40,
40, the collection chuck 19 is lifted by the elastic force of the spring 37, and the diameter of the upper part of the collection chuck 19 is reduced, and one side of the lipstick container etc. inserted into the recess 24 is clamped and fixed. be done.

Also, the air cylinder 43 has a slot 42.
At the same time as or after the rod 18 is raised, the air cylinder 16 is operated to lower the rod 18.

As the rod 18 is lowered, the support base 5 is lowered and comes into contact with the limit switch 45, and the lowering of the rod 18 is stopped by the operation of the limit switch 45.

In this state, the gripping device 29 operates. That is, the gripping parts 31, 31 of the air chuck 29 as a gripping device move from the position shown by the imaginary line in FIG. do.

Therefore, one side of the lipstick container or the like whose torque is to be measured is clamped and fixed to the collection chuck 19, and the other to the gripping parts 31, 31 of the gripping device 29. By activating it and rotating the output shaft 20 of the torque detector, the rotational torque of the lipstick container or the like is measured.

After the torque measurement is completed, the gripping device 29 is activated, and the gripping parts 31, 31 are rotated to the position indicated by the imaginary line shown in FIG. 3 to release the gripping of the other lipstick container or the like.

Thereafter, by performing the operations described above, such as raising the air cylinder 16, the rotational torque of the lipstick container, etc. can be sequentially and automatically measured.

Alternatively, a sliding member may be fixedly attached to the base plate as the collect chuck actuating device, and the diameter of the concave portion of the collect chuck may be expanded or contracted by moving the collect chuck up or down.

Furthermore, although the above embodiments have been described using air cylinders, the present invention is not limited to this, and a hydraulic cylinder may also be used.

"Effects of the Present Invention" As is clear from the above explanation, the present invention has the following effects.

Therefore, torque measurement work is easy.

(2) Since one side of the lipstick container, etc. can be automatically clamped and fixed between the collect chuck, the collect chuck actuating device, and the gripping device, the work of clamping and fixing one side of the lipstick container, etc., with the other is easy. be.

(3) With (1) and (2) above, the measurement work time can be significantly shortened.

(4) According to (2) above, even non-experts can perform correct measurements.

(5) Equipped with a collect chuck actuating device that expands the diameter when the collect chuck protrudes above the top surface of the base plate and contracts the diameter when it descends.
A lipstick container or the like that measures torque can be attached to or removed from the collection chuck at the location where the collection chuck is raised. Therefore, the lipstick container or the like whose torque is to be measured can be easily attached to and removed from the collection chuck.
