As shown in Figures 1 to 4, the multi-order parts sorting device is a device for picking up the parts loaded on the pallet by the robot to align the parts accurately before setting on the setting jig in the process, It is structured so that the parts of the specification can be efficiently aligned using one facility.

To this end, the device body 10 in the form of a frame structure for mounting the part is provided, the upper surface of the device body 10, that is, the plate installed on the upper end of the frame structure has a structure inclined to one side.

Accordingly, the part placed on the apparatus main body 10 can be automatically aligned on one side while sliding down naturally along the top plate of the inclined structure.

And the part guide roller 11 is provided as a means for guiding the movement of the part which falls down.

The part guide roller 11 is formed in a roller combination of three roller members in a bundle, and the three roller members are supported on both sides of the box-shaped roller bracket 21 along the direction in which the parts slide down. They are arranged side by side in a rotatable state.

These part guide rollers 11 are respectively provided on both sides on the upper plate of the apparatus main body 10 so as to stably support both sides of the part to guide the drop motion.

In this case, the part guide roller 11 is provided with a part detection sensor 22 in the form of a contact limit switch, and when the part detection sensor 22 is pressed by the part, the signal at this time is a pusher cylinder (to be described later). 16) can be used as an operation start signal.

In addition, the device body 10 is provided with a pusher device 12 as a means for pushing and aligning one end of the part.

The pusher device 12 is a means for pushing and aligning one end of the part toward the side of the part side guide 13 located thereon, and the pusher 15 which substantially pushes one end of the part. And a pusher cylinder 16 which is a driving source for operating the pusher 15.

The pusher 15 and the pusher cylinder 16 of the pusher device 12 can be installed in the following structure.

For example, the cylinder bracket 23 is vertically installed at one side of the upper plate of the apparatus main body 10, and the pusher cylinder 16 in a posture parallel to the side direction is horizontally installed at the upper end of the cylinder bracket 23. The holder plate 17 of the vertical posture is connected to the rod of the pusher cylinder 16.

At this time, two guide bars 24 parallel to the cylinder rod are connected to both rear surfaces of the holder plate 17, so that the front and rear linear movement of the holder plate 17 can be made more accurately.

The pusher 15 is composed of a pusher block 15b in contact with an end of the part and a pusher shaft 15a that moves together while supporting the pusher block 15b, wherein the pusher shaft 15a is a holder plate. The penetrating block of the pusher shaft 15a is installed in the structure of the pusher shaft 15a so as to penetrate horizontally through the block 17, and more precisely, to move freely back and forth while horizontally penetrating the block body at the end of the holder plate 17. 15b is integrally coupled.

Here, the pusher block 15b which is in direct contact with the part is preferably made of a material such as plastic or rubber, and one pusher block with two pusher shafts 15a up and down in order to move the pusher block 16b more stably. It is desirable to allow a form to support 15b.

In addition, a spring 18 is formed between the front surface of the block body in the holder plate 17 and the rear surface of the pusher block 15b coupled to the pusher shaft 15a.

At this time, the spring 18 is compressed when the pusher block 15b and the pusher shaft 15a are pushed to the rear, and exerts an elastic restoring force to move the pusher block 15b and the pusher shaft 15a to its original position (most forward). Position as shown), as well as the pusher block 15b serves to reduce shock while being in contact with the part.

Here, the pusher shaft 15a of the pusher 15 is composed of a catching portion 25 whose rear end has a diameter larger than the shaft diameter, and the catching portion 25 at this time is a block body on the holder plate 17. Since it is caught by the rear surface of the pusher shaft 15a, the pusher shaft 15a is not completely removed from the block body.

In particular, the pushers 15 of the pusher device 12 are constituted by a pair, and each pair is arranged with a height difference while maintaining a gap therebetween.

That is, among the pair of pushers 15, the rear pusher 15 is disposed on the upper side, and the front pusher 15 is disposed on the lower lower side, so that the two pushers 15 can be naturally pushed up and down the ends of the parts to be inclined. Will be.

Since the pair of pushers 15 can individually move forward and backward, they can push different ends of the part.

For example, when the end of the part has a stepped shape, each pair of pushers 15 respectively contact each stepped step of the part in a more advanced or more retracted position to conform to the shape of the stepped end of the part. As a result, even parts having stepped end portions can be aligned without problems.

In addition, the part side guide 13 which blocks the part pushed by the pusher device 12 on the other side of the device main body 10, that is, opposite the pusher device 12, corresponding to the pusher device 12. ) Is installed.

At this time, the part side guide 13 is in the form of a substantially vertical plate composed of two up and down, and serves to prevent the part from being pushed further to the side corresponding to the direction in which the pusher device 12 is pushed.

Then, the left and right two-part surface guide 14 for holding a part falling down is installed on the lower side of the upper plate of the apparatus main body 10.

At this time, the part surface guide 14 is formed in a roller shape that can be freely rotated about its own axis in a horizontal position, and the part surface guide 14 prevents the part from sliding down and at the same time the part is directed to the side. When it is pushed out, it also rotates through contact with the bottom of the part, guiding it to move sideways naturally.
At this time, the roller forming the part surface guide 14 has a multi-layered structure in which a plurality of concave grooves continuously formed in the circumferential direction on the outer peripheral surface of the roller are formed at regular intervals. This allows multiple parts with different bend radii of curvature at the bottom of the part to be aligned as they fit into grooves between different layers and layers of multi-layered rollers to align parts of various models with different shapes in one installation. It is possible to provide a multi-vehicle alignment device that can be made.

In addition, a pair of auxiliary guide rollers 18 are installed on the top plate of the apparatus main body 10 so as to be supported by a bracket, and the auxiliary guide rollers 18 are each part guide rollers 11. When the parts are placed on the device main body 10, that is, when the parts are placed on the device main body 10, the parts are lowered and loaded on the device main body 10 to guide the lowering of the part through contact with the parts.

In particular, the device main body 10 is provided with two cameras (19) that can detect the specifications of the part.

The camera 19 is disposed above the upper plate of the device main body 10, and serves to transmit a signal for detecting a specification of a part loaded in the device main body 10, and the detection signal at this time is a controller (not shown). It can be used to provide the robot to pick up the aligned parts by model at the same time without any problems such as equipment malfunction and system error.

In more detail, the controller receives an image signal of a part input from the camera, detects the shape of the part, and compares the shape (pixel) of each part of each model based on the detected shape of the part (pixel). If the part detected by is warned when a part different from the preset model comes in, or if the part is a preset model, it is determined which part of the model and then the pick-up part of the robot is placed at the picked-up position of the determined part. To control the operation.
