Description

[Detailed Description of the Invention] This invention relates to a material sorting device in a plate processing machine.

In general, a magnetic method or an air support method is often used to sort sheets cut by a sheet processing machine, such as a shearing machine.
However, the magnetic method is ineffective against nonferrous metals, and the air support method is ineffective against products with holes, for example.

In recent years, in the field of plate processing, as a means of responding to high-mix, low-volume production, a method has been adopted in which, for example, holes are formed using a turret punch press and then cutting is performed using an L-shaped shearing machine. On the other hand, in response to the trend toward flexible FMS, it is necessary to mix and sort several types of products on one plate processing machine, which is no longer possible with conventional material sorting equipment. ing.

This invention was devised in view of the above-mentioned prior art, and its first purpose is to provide a material sorting device whose sorting performance is not impaired by the type of material, such as ferrous or non-ferrous.

A second objective is to provide a material sorting device whose sorting performance is less likely to be limited by the shape of the material, such as the presence or absence of holes. A third object is to provide a material sorting device that can efficiently sort materials to desired positions, taking into consideration the size of the materials.

This invention to achieve the above object supports both sides of the conveyed material conveyed in the longitudinal direction by approaching and separating them according to the width of the material, and supports the conveyed material parallel to the conveying direction on the side of the conveying position of the material. A pair of conveyors that move horizontally in cooperation with each other are provided at sorting positions arranged in parallel, and an endless body that moves in a direction perpendicular to the conveying direction is provided, and a frame of each of the pair of conveyors is provided with a pair of conveyors that move laterally in cooperation with each other. A material sorting device, characterized in that arms are provided extending toward each other, and a clamping device for selectively gripping one or the other of the endless bodies is provided on the arm of at least one of the pair of conveyors. be.

Hereinafter, this invention will be described in detail using examples and accompanying drawings.

Figure 1 shows plate material processing machine 1 such as an L-type shearing machine.
FIG. 2 is an explanatory diagram showing an outline of a system for sorting materials carried out from a warehouse. The plate material carried out from the plate processing machine 1 is sorted and conveyed in the following order: a carry-out conveyor 3, an elevating sorter 5, and a material sorting device 7.

The elevating sorter 5 has a scrap chute 9 below. Further, the elevating conveyor 11 has a cylinder 15 that swings an interlocking arm 13, and is elevated and lowered in three stages. In the upper stage, the scraps that have been conveyed are dropped into a scrap chute 9. In the middle stage, the first product group is transferred to a pair of conveyors 1 of the material sorting device 7.
7 (FIG. 2 17a, 17b), and in the lower stage, the second product group is transported to a telescopic conveyor 19 provided in the material sorting device 7. Of course, the sorting operation of the cylinder 15 is controlled by a numerical control device (not shown) depending on the type of material.

Telescopic conveyor 1 passing through material sorting device 7
9 receives the material from the lower stage of the elevating sorter 5 and conveys it onto the trolley 21. The conveyor tip 23, which is expanded and contracted by a suitable expansion and contraction mechanism such as a cylinder, is capable of conveying materials to a plurality of carts 21 and 25 arranged in series. The telescoping conveyor is used to sort relatively small materials.

FIG. 2 shows an enlarged cross-sectional view of FIG. 1 taken along the - arrow, and FIG. 3 shows an enlarged cross-sectional view of FIG. 2 taken along the - arrow.

The material sorting device 7 has a sorting device that supports both sides of the conveyed material conveyed in the longitudinal direction by approaching and separating them according to the width of the material, and is arranged parallel to the conveyance direction on the side of the conveyance position P ₀ of the material. A pair of conveyors 17, 17 that move horizontally in cooperation with positions P ₁ and P ₂
a and 17b are provided. Further, an endless body 31 that moves in a direction perpendicular to the conveyance direction (arrow 29 in FIG. 2) is provided in a stretched manner. The endless body 31 is composed of a chain, which can be rotated in both directions by a moving motor 35 via sprockets 33, 33.

Arms 37a and 37b are respectively extended toward the endless body 31 on the respective frames of the pair of conveyors 17a and 17b. At least one of the arms 37, 37a, 37b is provided with a clamp device 39 for selectively gripping one 31a or the other 31b of the endless body. In this example, a clamp device 39 is provided on the right arm 37b in FIG. 2, and the left arm 37a is fixed to the other arm 31b of the endless body 31.

Carts 41a and 41b are provided at the left and right sorting positions _P2 and _P1 , respectively, on which sorted materials are placed.

FIG. 3 shows the material sorting device 7 in more detail. Each conveyor 17, 17a, 17b
is provided with a stopper 43 for regulating the tip of the material W and a limit switch LS for detecting the abutment position,
A drive motor 45 is provided to drive the conveyor. The support column 47 of the material sorting device 7 is provided with an arm 37 extending from the frame 51 of the conveyor 17 via slide guides 49a, 49b, and the arm 37 is provided with clamp devices 39, 39.

The clamping device 39 has an upper clamp 53 and a lower clamp 55, and is configured to selectively grip the upper or lower gripping plate 61 of the endless body 31 by vertically moving an operating pin 59 of an electromagnetic operating body 57. The sprockets 33, 33, which rotate the endless body 31 in both directions, are connected by a connecting shaft 63 for synchronization. The clamp device is provided with restoring springs 65, 65 so as not to grip the grip plate 61 of the endless body 31 when the actuation pin 59 of the electromagnetic actuator 57 does not act.

The operation of the material sorting device with the above configuration will be explained.

In Fig. 1, relatively large materials transported from the middle stage of the elevating and descending sorting machine are transferred to a pair of conveyors 17.
heading to

A pair of conveyors 17a and 17b shown in FIG.
Of these, the left conveyor 17a is fixed to the other end of the endless body. Therefore, it is possible to move left and right by rotating the endless body. Furthermore, the clamping device 39 provided on the right conveyor 17b can selectively grip one or the other of the endless bodies 31, so that it can be moved left or right by gripping one or the other of the endless bodies. be. Therefore, the pair of conveyors 17a and 17b are
Both are movable left and right, and can move according to the width of the material to support both sides of the material.

Even if the material is relatively large, it can be supported and transported without deforming the material because both sides are equally supported within the same plane as the elevating and lowering sorter. Incidentally, since the width of the material and the like are known in advance, the movement of the endless body and the gripping operation of the clamp device of the conveyor 17b can be performed by commands from the numerical control device.

The materials supported by the pair of conveyors 17 are
It is transported in the transport direction. As shown in FIG. 3, the conveyor is driven by a drive motor 45. When the tip of the material W reaches the position of the stopper 43, the limit switch LS is turned on, the completion of the abutment is notified to the numerical control device, and the drive motor 45 is stopped.

In FIG. 2, the pair of conveyors 17 are maintained at the same distance, that is, the conveyor 17a is fixed to the other end of the endless body 31.
7b similarly grips the other end of the endless body 31 with the clamp device 39 and rotates and moves the endless body. The pair of conveyors that have moved to the desired material sorting position P ₂ or the upper surface of P ₁ widen the distance between them facing each other. That is, one conveyor is stopped and the other is moved away, or both conveyors are moved away.
The material supported by the pair of conveyors is then dropped from a predetermined position onto the carriage 41a or 41b.

The above transport and dropping method is not affected by the type of material, such as ferrous or non-ferrous, and can be applied to many shapes, and in particular, it is not affected in any way even if there are holes in the material. . Note that the material sorting positions P ₂ and P ₁ are not limited, and can be arranged in a desired plurality of rows. Therefore, the size of the materials can be taken into account and the materials can be sorted into desired positions with ease.

In short, since the gist of this invention is as stated in the claims for utility model registration, the sorting performance is unlikely to be limited by the shape of the material, such as the presence or absence of holes, regardless of the material, such as ferrous or non-ferrous. It is possible to provide a material sorting device that can efficiently sort materials to desired positions by taking size into consideration.

Note that the present invention is not limited to the above-mentioned embodiments, and by making appropriate design changes,
It is possible to implement the present invention in a manner other than the embodiments described above.
