Description

[Detailed description of the invention] The present invention is equipped with a lifting platform, a carry-in conveyor, a bridge, and a pusher. DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a work loading device (hereinafter referred to as the device) that can efficiently and accurately stack workpieces will be described below with reference to the drawings.

In the figure, the device 1 of the present invention includes a lifting platform 3 provided with a stopper 2 at one end a, a carry-in conveyor 4 adjacent to the other end b, a bridging device 6 having a protrusion 5 that can move forward and backward, and a pusher. The lifting platform 3 is a so-called table lifter in which a base frame 11 and an upper plate 12 above the base frame 11 are connected by a cross link 13 that opens and closes.
2, the stopper 2 is provided at one end a thereof protruding near both ends. The stopper 2 has a piece 17 that extends vertically at one end edge of a pallet 16 placed on the upper plate 12 attached to the inner side of a vertical piece 15 rising from the upper plate 12 via a spring 19. There is.

The carry-in conveyor 4 is a strut in which a chain 25 is wound around a chain wheel 23 that is pivoted by side plates 22 that are erected along both side edges of a frame base 21 and protrudes outward, and a chain 25 that is continuously provided with blade plates 24. Consisting of a conveyor,
The loading conveyor 4 has its front end connected to the lifting platform 3.
It is arranged on both sides of the frame 21 so as to be separated from the other end b by a small gap, and the carrying-in conveyor 4 carries in a long workpiece W made of, for example, a channel-shaped material in a horizontally elongated manner with its groove facing upward. .

The bridging tool 6 supports a sliding frame 29 on a guide shaft 27 disposed on the upper surface of the frame 21 and in the vicinity of the side piece 22, and has projecting pieces on both front ends of the sliding frame 29. 5, 5 are provided protruding toward the lifting platform 3, and a rod of a cylinder 31 attached to the frame base 21 is connected to a downwardly protruding portion 30 provided at the center of the sliding frame 29. There is. Further, the protruding piece 5 is
It is a relatively long piece with a circular arc at the tip c, and as mentioned above, it extends from the carry-in conveyor 4 and is separated by a small gap from the vicinity of the one end a of the lifting platform 3 to the other end b by the expansion and contraction of the cylinder 31. The tip c moves back and forth between it and the vicinity, and the upper surface of the protruding piece 5 is set slightly lower than the carry-in conveyor 4, so that the workpiece W on the carry-in conveyor 4
is transferred to the upper surface of the protruding piece 5 and slid on the upper surface.

The pusher 9 has a cylinder 34 fixed to the back side of a hanging piece 33 at the lower end of the horizontal frame 32 which is fixed to a floor body or the like as appropriate, and which crosses above the loading conveyor 4.
Further, a support frame 35, which pivotally supports the upper end of the press 7 at both ends thereof, is fixed to the rod. Further, the support frame 35 is provided with a locking piece 37 that comes into contact with the back surface of the pusher piece 7, and the pusher piece 7 is freely lifted up when the workpiece W to be carried in comes into contact with the lower end, and the workpiece W passes through. On the other hand, in the opposite direction, the locking piece 37 engages with the back surface, and the flip-up is prevented. Note that a guide shaft 39 extending from the support frame 35 is inserted into the hanging piece 33 to prevent the support frame 35 from rotating, and the pusher 9 advances to the other end b of the lifting platform 3 due to the extension of the cylinder 34, and the pusher 9 advances to the other end b of the lifting platform 3 due to the extension of the cylinder 34. 2, the workpiece W is clamped and pressed between the projecting piece 5
moves backward during this clamping pressure.

However, in the device 1 of the present invention, the cylinder 31
As a result of the extension, the projecting piece 5 of the bridging tool 6 bridges between the carry-in conveyor 4 and the vicinity of one end a of the lifting platform 3 as described above, and as shown in FIG. When the work W is received and pressed by the following work W, the work W is slid until it comes into contact with the contact piece 17 of the stopper 2. Incidentally, the lifting table 3 rises and pushes up the pallet 16 disposed on its upper surface to a height located near the lower surface of the projecting piece 5. Further, the pushing piece 7 collides with the workpiece W and is thrown up, allowing the workpiece W to freely pass below.

In addition, the workpiece W is placed on pallet 1 as shown in Fig. 3.
When the number of workpieces W that covers almost the entire width of the workpiece W is carried in, the cylinder 34 is extended and the pusher piece 7 is advanced, and the workpiece W
By pinching and pressing between the stopper 2 and pulling out the protruding piece 5 and retracting the pressing member 7,
Workpieces W can be stacked in one layer on the pallet 16 (as shown in FIG. 4). After that, the lifting table 3 is lowered downward by the height of the workpiece W, and the projecting piece 5 is brought close to the upper surface of the workpiece W and protruded, and by repeating the same operation, the workpieces W can be stacked in multiple stages. .

As mentioned above, the device of the present invention is equipped with a lifting platform, a carry-in conveyor, a bridge, and a pusher, and can efficiently and accurately stack long workpieces such as channel-shaped materials in multiple stages. Work efficiency can be improved. Note that a belt conveyor or a roller conveyor in which rollers are arranged relatively closely in parallel can be used as the carrying-in conveyor, and a suitable moving device such as a free roller is attached to the top surface of the protrusion to facilitate sliding of the workpiece. The device of the present invention can be modified in various ways.
