Description

[Detailed Description of the Invention] The present invention relates to an improvement of a pusher that pushes out plate-shaped pressed products stacked in a magazine one by one from the magazine for secondary pressing.

In this type of conventional pusher, a pusher plate having a step is placed below the lowest workpiece in the magazine, and the lowest workpiece is hooked to the step of the pusher plate to advance the pusher plate. This allows the workpiece to be pushed out of the magazine, but when the thickness or shape of the workpiece changes, the pusher plate is replaced accordingly.

However, pusher plates are expensive because they are made of wear-resistant material, and preparing a large number of such pusher plates depending on the thickness and shape of the workpiece increases costs.

In addition, since the pusher plate moves at a high speed, the workpiece will fly out before the pusher plate, so a stopper is provided in front of the pusher plate to stop this. When changing to a curved shape, it was troublesome because it had to be replaced.

Furthermore, conventional pusher plates have been known in which a recess is formed in the pusher plate, and a workpiece is dropped into the recess and ejected, but this method cannot be used in accordance with the thickness and shape of the workpiece.

The purpose of the present invention is to provide a pusher that can be easily adapted to changes in the thickness and shape of a processed product at a low cost.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view thereof, and FIG. 2 is a front view thereof. The plate-shaped workpieces stacked in the magazine 1 are ejected from inside the magazine 1 to the right in FIGS. 1 and 2.

The magazine 1 is separated from a partition plate 2, a partition post 3, and a support member 4.

The partition plate 2 is attached to a partition post 3, and the partition post 3 is supported by a support member 4.

The support member 4 is fixed to the base 5. The support member 4 and the base 5 are provided with long grooves 6 and 7, and the support member 4 is fixed by bolts 8 and nuts 9 passing through the long grooves 6 and 7, so the position of the support member 4 can be adjusted according to the dimensions of the workpiece. Adjustments can be made in the vertical direction or horizontal direction in FIG.

If the shape of the workpiece is circular or has another curved line, partition plates and partition columns are used that match the shape.

Two pusher plates 10 are disposed at the bottom of the magazine 1 so as to be slidable on a base 5.

Inside the magazine 1, workpieces 11 are stacked on a pusher plate 10 as shown in the opening of FIG. 3, and the pusher plate 10 slides while supporting the workpieces 11.

A set plate 12 is fixed to the pusher plate 10 with screws 13.
4 and T-nut 15 to fix it to the bush holder 16.

Since the T-nut 15 is slidably fitted into the T-slot 17 of the bushing holder 16, the fixing position of the set plate 12 to the bushing holder 16 can be adjusted in the vertical direction in FIG.

The bush holder 16 is connected to a cylinder sevent 19 via a cylinder end fitting 18.

An air cylinder 20, which constitutes an example of a drive unit for reciprocating the pusher plate 10, is attached to the mounting plate 2.

The bottom of the bush holder 16 fits into a guide rail (not shown) provided in the groove 22 of the base 5, so that the moving direction of the bush holder 16 and the pusher plate 10 is accurately determined.

A workpiece unloading member 23 having an upper surface matching or slightly lower than the upper surface of the pusher plate 10 is detachably attached to the front portion of the pusher plate 10 .

A recess 24 matching the shape and dimensions of the workpiece 11 is formed on the upper surface of the workpiece delivery member 23 .

The recess 24 in the illustrated embodiment is adapted to a rectangular workpiece 11.

When the pusher plate 10 is moved to the left in FIGS. 1 and 2 by the return operation of the air cylinder 20 from the position of the pusher plate 10 shown in FIGS. While sliding on the workpiece 11 in the magazine 1, it returns to the position shown in FIG. 3A.

In this position, the recess 24 of the workpiece delivery member 23 fits into the magazine 1, and the lowermost workpiece 11 falls into the recess 24.

Since the depth of the recess 24 from the top surface of the pusher plate 10 matches the thickness of the workpiece 11, the air cylinder 20
When the pusher plate 10 is moved to the right in FIG. 1 by the operation of FIG.

In this position, the workpiece 11 is removed from the recess 24 by the arm of the industrial robot and selected to the processing position.

Since the workpiece delivery member 23 does not need to be made of a wear-resistant material, costs can be kept low even if a large number of workpiece delivery members 23 are prepared depending on the thickness and shape of the workpiece.

Further, even if the moving speed of the pusher plate 10 is increased, the processed product does not fly out of the recess 24, so there is no need to provide a stopper as in the conventional case.

Therefore, even if the shape of the processed product changes, the processed product delivery member 2
It is easy as you only need to replace 3.

In the illustrated embodiment, the recess 24 has edges 24 on all four sides.
a, 24b, 24C, and 24d, but if the workpiece is rectangular, the vertical edges 24c and 24d shown in FIG. 1 may be omitted.

In the present invention, a workpiece delivery member having an upper surface that matches or is slightly lower than the upper surface of the pusher plate is detachably attached to the front part of the pusher plate.
Since a recess that matches the shape and dimensions of the workpiece is formed on the top surface of the workpiece delivery member, the thickness and shape of the workpiece can be changed by preparing the workpiece delivery member in accordance with the shape and dimensions of the workpiece. This can be done easily and at low cost without requiring replacement of the expensive pusher plate, which is wear resistant.

In addition, the magazine is composed of a partition plate, a partition column, and a support member that supports the partition plate and the partition column, and the support member is fixed to the base so that its position can be adjusted forward, backward, left, and right, and the interval between the two pusher plates is adjusted. The pusher plate is connected to the drive unit for reciprocating motion via the bush holder, so that the size of the magazine and the spacing between the pusher plates can be adjusted according to the shape of the workpiece. Changes can be accommodated more easily.
