It is divided into loading equipment and unloading equipment. This loading device for the plate material W includes a material table 3 that is movable orthogonally to the plate material conveyance line, and a plate material gripping device that grips the plate material W placed on the material table 3 and picks up the plate IIW by suction. It is composed of a suction device 5 and a sheet material conveying device 7 that conveys the suction-lifted sheet material W to the turret punch press 1.

As a device for carrying out the plate material W, there is an unloader 9 for carrying out the plate material W, which is a product after press working, and a lifter table with a traveling device, which is provided on the lower side of the material table 3 and which loads and carries out the plate material W, which is a product. It consists of 11.

In the material table 3 which is a plate material carrying device, a base 17 equipped with a plurality of wheels 15 is movable on a rail 13 provided orthogonally to the carrying direction as a conveying direction for conveying the plate material W to the turret punch press 1. It is set in. Although not shown, the base 17 is moved via a drive mechanism such as a motor.

Boards W, which are raw materials, are stacked on the base 17 via a pallet 19, and a guide rod 21 is provided at an appropriate position to serve as a reference for the placement position of the boards W and to prevent shifting.

In the suction device 5, a plurality of suction bats 25 are installed vertically on a vacuum hanger 23 which is vertically installed from the sheet material conveying device 7, and can freely adsorb or remove the sheet material W using a vacuum source (not shown).

The operation of the plate material conveying device 7 is NC, and a frame 33 is engaged with a rail 31 provided at the tip of an arm 29 extending from the frame 27 so as to be freely movable back and forth in the conveying direction (left and right in FIG. 1). It is moved on the rail 31 via a drive mechanism (not shown) by an electric motor 35. The vacuum hanger 23 of the suction device 5 is vertically installed on the frame 33 via a guide portion 37, and the vacuum hanger 23 can be raised and lowered by a cylinder 39 which is supplied and operated from a pneumatic source (not shown). In addition, in FIG. 1, the state in which the plate material W is carried into the turret punch press 1 by the plate material conveyance device @7 is shown by a chain line.

The unloader 9, which is a plate material unloading device, is connected to the frame 27.
A clamping device 41 is installed in the
and a roller conveyor device 43.

In the clamp device 41, a clamp frame 47 is vertically mounted on a rail 45 provided on the side wall of the frame 27, and one end of the clamp frame 47 is locked to a chain 53 that is wound around each sprocket 51 by an electric motor 49, so that the clamp frame 47 is moved in the direction of sheet material conveyance. It can move forward and backward. A plurality of clamps 55 are arranged on the clamp frame 47 to clamp the end surface of the plate material W. The structure of the clamp 55 is commonly used in this type of machine and is well known, so a detailed explanation will be omitted.

The roller conveyor device 43 is for guiding the plate material W moving on the pass line indicated by the X-X line, and a chain 59 that engages both ends of the shafts of an appropriate number of freely rotatable rollers 57 is installed on the frame 27. A sprocket 63 is fixed to an electric motor 61, a sprocket 69 is provided at both ends of a connecting shaft 67 rotatably supported by a bearing 65 on the frame 27, and sprockets 71 and 73 are placed at appropriate locations.

By rotating the electric motor 61, the roller 57
- Move forward one distance along the pass line indicated by the X-ray, and roll 5.
7 Guide the board W on top. However, when transporting the plate material W, make sure that it does not interfere with the operation of the suction device 5.
In addition, a plurality of rollers 5 are provided from the reference end surface 7 on which the plate materials W are stacked so as not to get in the way when the plate materials W as a product are stacked on a lifter table 11 with a traveling device to be described later.
The condition is that the most advanced roller surface of No. 7 is in the retreated position, that is, in the standby position.

The lifter table 11 with a traveling device is provided with a plurality of wheels 77 on a rail 75 provided inside the rail 13 of the material table 3, orthogonal to the carrying direction in which the plate material is transported to the turret punch press 1. is set up so that it can be moved freely. Although not shown in the drawings, the lifter table 11 is moved via a drive mechanism such as a motor, so that it can move in and out of the base 17 of the material table 3.

Although the lifter table 11 is not shown, it is provided with a telescopic mechanism 79 that can be raised and lowered by, for example, a hydraulic cylinder, and the plate materials W as products are stacked on a pallet 81 provided on the lifter table 11. A guide rod 83 is provided to guide the plate materials W of the stacked products.

With the above configuration, the functions shown in Figures 4 to 12 are as follows.
Referring to the figures, FIGS. 4 to 8 show the state in which the plate material W is carried into and out of the turret punch press 1, and
From the figure, FIG. 12 shows the operating state of the unloader 9.

FIG. 4 shows the initial state, in which the material table 3 and the lifter table 11 with a traveling device are installed in the plate material conveyance line, and the plate material W as a raw material and the plate material W as a product are stacked Φ, respectively.
The 0-ra conveyor system @43, the clamp device 41, and the plate material conveyance device 7 of the unloader 9 are located at the backward limit, which is the standby position.

From this state, the suction device 5 descends to the state shown in FIG. 5, suctions one sheet of material W on the material table 3, and ascends. At this time, it goes without saying that in order to reliably take out one board, a single board removal detection means J3 and other control means are provided.

Next, as shown in FIG. 6, the plate material conveying device 7 is advanced and the plate material W is
is carried into the processing position of the turret pan de press 1.

FIG. 7 shows the arrangement of the equipment in a plan view. After releasing the suction of the suction device 5 from the state shown in FIG. The plate material W to be processed is suctioned and pulled up by the suction device 5, and then the material table 3 is moved to the outside of the plate material conveyance line. (In FIG. 7, the material table 3 moves from the position of the dotted line to the position of the solid line.) From the above state, as shown in FIG.
1 is moved forward, the end face of the plate material W as a product is clamped, the roller 57 of the roller conveyor device 43 is set at a predetermined position, and the plate material W is carried out using the roller 57 as a guide. At the same time, since the sheet material W to be processed next is already suctioned and held by the suction device 5, the sheet material transporting device 7 releases the suction at a predetermined processing position after transporting it to the turret punch press 1, and the sheet material transporting device 7 retreats. will move to a limited period.

The plate material W, which is a product, is placed on the lifter table 11, and at the same time the lifter table 11 is lowered, and after the descent is completed, the material table 3 moves to the plate material conveyance line and enters the initial state shown in FIG. 4, and the above-mentioned operations are performed. The work of loading and unloading the plate material W is carried out repeatedly.

The operation of the unloader 9 will be explained in more detail with reference to FIGS. 9 to 12.

FIG. 9 shows the initial state of the unloader 9, in which the clamp device 41 is located at the backward limit, and the rollers 57 of the roller conveyor device 43 are moved forward to a predetermined position to support the processed product. Raise it to a predetermined height for stacking. In addition, the unloader 9 is
It is possible to change the loading position on the lifter table 11 according to the controlled length of the product. For example, as shown in the figure, if the plate is based on the end face of the plate, it is at the T position, and if the plate is based on the center, it is at the 1S position indicated by the chain line. W can be multiplied by w4.

Next, as shown in FIG. 10, the clamp device @41 is moved forward to clamp the end face of the plate material W, which is a processed product.

Then, as shown in FIG. 11, the plate material W, which is a product, is carried out. At this time, if the length of the plate material W is short, the plate material W
When the rear end reaches the vicinity of the leading edge of the roller 57 of the roller conveyor device 43, passing of the rear end of the plate material W is detected by a detection means (not shown).

In response to the detection signal, the plate material W to be processed next is already being suctioned and held by the suction device 5, so the plate material conveying device 7 is activated to start carrying it into the turret punch press 1. Further, when the length of the plate material W as a product is long, the roller conveyor device 43 composed of a plurality of rollers 57 cannot support the entire length of the plate material W, so the rollers 57 are moved to a position where it can be supported appropriately. .

Thereafter, as shown in FIG.
The plate material W, which is a product, is placed on the lifter table 11 by activating the lifter to move to the backward limit, that is, to the standby position, and releasing the clamp of the clamp device 41.

Due to the above-mentioned effect, conventionally, even if the length of the plate material is short, the plate material conveying device cannot transport the plate material to the plate processing machine unless the unloader device moves to the backward limit. However, in the present invention, when a short product leaves the plate processing machine and reaches a predetermined position, the next plate can be carried into the processing machine and set.

Therefore, it is possible to significantly reduce the time required to replace the product and the plate material, and there is no need to adjust the number of rows 557 that support the plate material to the maximum length of the plate material. can be retained.

Furthermore, the material table 3 on which the plate material W, which is the raw material, is placed and the lifter table 11 on which the product is placed are installed above and below, and can be inserted into and taken out from the plate material conveyance line from the same direction, which occupies significantly less space than before. It is possible to reduce equipment costs.

It goes without saying that the invention is not limited to the embodiments described above, and that various changes can be made without departing from the gist of the invention.

[Effects of the Invention] As can be understood from the above description of the embodiments, according to the present invention, it is possible for the person processing the plate material or the output side to transfer the material to one side perpendicular to the conveyance line of the plate processing machine. By providing a material table on which the material is placed and a lifter table with a traveling device on which a product that can be freely inserted is placed inside the material table, the equipment area can be significantly reduced and equipment costs can be reduced.

However, since the unloader is equipped with a clamp device and a roller conveyor device that are movable in the transport direction, the stacking position of the products can be changed depending on the size of the workpieces.
