Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stacking device for rectangular bars, which is capable of sequentially stacking rectangular bars of a predetermined length and taking them out, for example, by a drawing machine or the like.

Conventionally, the rectangular bars drawn out by a drawing machine were stacked one by one based on the operator's input, which resulted in poor workability and required a lot of labor if the rectangular bars had a large weight. The work was dangerous. For this reason, there is a need for a device that automatically aligns and stacks the rectangular bars drawn out by the drawing machine, but the movement path of the rectangular bars is equipped with moving parts of the drawing machine that chucks and draws out the bars. Because it passes through, it was not possible to install a member to receive or carry out the rectangular bar.

SUMMARY OF THE INVENTION An object of the present invention is to provide a rectangular bar stacking device that can receive, sequentially stack, and take out rectangular bars without interfering with the feeding of the rectangular bars.

Embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1 and 2 show a rectangular bar stacking device 10 according to the present invention. Carriage 1 that feeds out the bar 18
a plurality of receiving arms 20 that are provided at intervals along the travel path of No. 6, that is, a movement path of the rectangular bars 18, and receive the rectangular bars; and a pedestal that sequentially receives the rectangular bars 18 from above the plurality of receiving arms 20. It consists of 22.

The device 10 of the present invention further has a retracted position (solid line position in FIG. 1) in which the plurality of receiving arms 20 are parallel to and retracted to the side of the path of movement of the rectangular bar 18, and a position perpendicular to the path of movement of the rectangular bar 18. The receiving arm rotating means 24 rotates between the forward position (the chain line position in FIG. 1) that receives the rectangular bars 18, and the rectangular bars 18 thereon slide down the plurality of receiving arms 2 in one direction. As shown in FIG. 2, a plurality of receiving arms 20 are tilted between an inclined position (the chain line position in FIG. 2) and a horizontal position (solid line position in FIG. 2) in which the plurality of receiving arms 20 receive the rectangular bars 18. The arm tilting means 26 is also provided.

As shown in FIGS. 3 and 4, the receiving arm rotating means 24 includes a support shaft 28 that is rotatably supported by a support cylinder that is vertically attached to one end of each receiving arm 20 and extends behind the receiving arm tilting means 26. It consists of a pinion 30 fixed to the support shaft, a rack 32 that meshes with the pinion, and a cylinder 34 that moves the rack 32 back and forth, and the cylinder 34 is supported by a movable frame 36. Therefore, cylinder 3
When the cylinder 4 is extended, the rack 32 moves forward and the receiving arm 20 is moved to the retracted position, and when the cylinder 34 is retracted, the rack 32 is moved back and the receiving arm 20 is moved to the retracted position.
0 to the forward position.

As shown in FIG. 4, the receiving arm tilting means 26 includes a support cylinder 38 that is attached to the movable frame 36 and rotatably supports the support shaft 28, and a horizontal rotation shaft 40 that locks the bracket 36a of the movable frame 36. Machine frame 4
An arm 46, which is pivotally supported by a piston 44a of the cylinder 44, is keyed to a horizontal rotation shaft 40. Therefore, when the cylinder 44 is extended, the horizontal rotation shaft 40 rotates in the counterclockwise direction in FIG. When the cylinder 44 contracts, the receiving arm 20 returns to the horizontal position.
Note that the horizontal rotation shaft 40 and cylinder 44 are commonly used for all receiving arms 20.

The pedestal 22 has a stopper 48 on its upper surface for receiving the first stack of rectangular bars 18, and this pedestal 48 can move forward and backward relative to the outlet edge 20a of the receiving arm 20, as shown in FIG. It is preferable to include wheels 50 that run on rails and a cylinder (not shown) that runs on this pedestal 22. Note that this pedestal 22 may be formed of a conveyor belt, and more preferably, the upper surface of the pedestal 22 can be moved up and down with respect to the outlet edge 20a of the receiving arm 20.

Next, the operation of the apparatus of the present invention will be described. As shown in FIG. Grip the tip and pull it out from the die 14 in the direction of the arrow.
Thereafter, the receiving arm rotation means 24 moves the receiving arm 20 to the forward position, the chuck of the carriage is removed, and the rectangular bar 18 is received on the receiving arm 20. Incidentally, as the rectangular bar 18 is drawn, the receiving arm 20 on the die 14 side may be moved to the forward position sequentially. Next, the receiving arm tilting means 26 is operated to place the receiving arm 20 in an inclined position as shown by the chain line in FIG. The pedestal 22 is initially in a position where the stopper 48 receives the first rectangular bar 18. Next, the receiving arm 20 is returned to the horizontal position and the retreated position, and the second rectangular bar 1 is moved in the same manner as before.
8 are aligned and stacked on the first rectangular bar 18. In this way, the rear pedestal 22 on which the three rectangular bars 18 are stacked is moved to the left in FIG. 2 by the width of the rectangular bars to form the second, third,... material stack. do. Materials stacked in several rows are placed on a pedestal 22
At the top, it will be carried out using a crane, etc. In addition, flat bar 1
In order to prevent the parts 8 from being damaged on the receiving arm 20 and to improve the sliding thereof, a protective layer 20b (FIG. 4) is provided on the upper surface of the receiving arm 20, which is made of nylon or Teflon (trade name) and has good elasticity and good sliding. Preferably, an elastic protective layer (not shown) is preferably provided on the top surface of the rectangular bar 18 to prevent it from being damaged when it falls onto the pedestal 22.

According to the present invention, as described above, the rectangular bars are automatically stacked one after another, resulting in good workability and safety, and the receiving arm that receives the rectangular bars retreats when the material is fed out. Moreover, since the material is carried out to the side of the material movement path, there is no interference with the material delivery.
