Air is supplied to E to reduce the size. Then, in step 6, it is determined whether or not a predetermined time t ₁ required for gripping the dials 28A and 34A by each air chuck 43E has elapsed, and if “YES” is determined, each air chuck 43E is determined.
Since the gripping of the dials 28A and 34A by means of is completed, the process proceeds to step 7 and the supply of air to the air chucks 43E is stopped.

Next, in step 8, the current value of each stepping motor 44 is read, in step 9, the command value corresponding to the outer diameter dimension of the bottle 6 is read, and in step 10,
Calculate the calculated value by calculating the difference between this command value and the current value,
The rotation amount of each stepping motor 44 is determined. Then, in step 11, each stepping motor 44 is rotationally driven, and in step 12, each stepping motor 44 is driven.
It is determined whether or not the rotation amount of has reached the calculated value calculated in step 10, and if “YES” is determined, step 13
Then, each stepping motor 44 is stopped, and in step 14, a new current value after rotation of each stepping motor 44 is stored.

Next, in step 15, the air in each air chuck 43E is discharged, and in step 16, a predetermined time t
_It is determined whether or not _{2 has} elapsed, and if "YES" is determined, the process proceeds to step 17 to drive each air cylinder 43B to reduce, and in step 18, it is determined whether or not a predetermined time t _{3 has} elapsed and "YES". If it is determined that, the process returns to step 1 and the above-described operation is repeated.

Thus, in this embodiment having the above-described structure, the same operational effect as that of the first embodiment can be obtained. In particular, in this embodiment, the bottle positioning jig 23 is Since the automatic adjustment mechanism 42 automatically adjusts to correspond to the shape change of the bottle 6, it is possible to reliably prevent human error during adjustment work, and further improve productivity. You can

In the above-mentioned embodiment, the case where the bottle positioning jig 3 is used in the automatic filling line 1 for filling the bottles 6 and 6'as the transported objects with the filling such as the lotion is taken as an example. Although explained, it may be used in place of this, for example, in an automatic production line for compacts made of solid powder cosmetics, an automatic production line for lipsticks, and the like.

Further, the first moving mechanism 27 and the second moving mechanism 3
3 has been described as interlocking the sub-screw screws 29, 35 with the main screw screws 28, 34 via the timing belts 30, 36.
A sub-screw screw 29, 35 is replaced with a main screw screw 2 by using a connecting member such as a chain or a V-belt in place of 36.
You may make it interlock with 8 and 34.

[0064]

As described in detail above, according to the present invention, the object positioning jig is provided with a case for carrying the object along the conveyor of the production line, and the case is provided inside the case. A plurality of first adjusting plates provided so as to be movable in the left and right directions according to the shape of the conveyed object, and in a direction orthogonal to the moving direction of each of the first adjusting plates according to the shape of the conveyed object. It is composed of a plurality of movably provided second adjusting plates, and by moving and adjusting each of the first adjusting plate and the second adjusting plate, the shape is adapted to the shape of the transported object. Therefore, even if the shape of the transported object to be positioned by the transported object positioning jig is changed, the transported object can be easily handled by adjusting the first adjusting plate and the second adjusting plate. Workability when changing the shape of the transported object because it can be positioned at a predetermined position Enhance the productivity can be improved by.

Further, since an automatic adjusting mechanism for adjusting each of the first adjusting plate and the second adjusting plate according to an external signal is provided in the middle of the conveyer conveyor of the production line, each time the shape of the conveyed object is changed. Since the first adjusting plate and the second adjusting plate can be automatically adjusted, the workability can be prevented from deteriorating due to human error and the productivity can be further improved.
