Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for aligning and stacking 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 on top of the other by a worker's manual effort, which resulted in poor workability, and if the rectangular bars had a large weight, it required a lot of labor and the work was difficult. Was it dangerous? -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 provided with the movable parts of the drawing machine that chucks and draws out the bars. It was not possible to install a member to receive or carry out the rectangular bar because it passed through it.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus for aligning and stacking rectangular bars, which is capable of receiving rectangular bars, sequentially stacking them, and taking them out.

Embodiments of the present invention will be described in detail with reference to the drawings.
Figures 1 and 2 show an apparatus 1 for aligning and stacking rectangular bars according to the present invention.
0, and this device has a plurality of devices installed at intervals along the traveling path of the carriage 16 that feeds out the rectangular bars 18 from the die 14 of the drawing machine 12, that is, the movement path of the rectangular bars 18, and that receives the rectangular bars. The receivers are an arm 20, the receivers are an arm rotation means 22 for rotating the arm 20 between a forward position and a retracted position, and the receivers are an arm tilting means 24 for tilting the arm 20. It is equipped with

As shown in FIGS. 3 and 4, the arm rotating means 22 is a support that is vertically attached to one end of the arm 20 and is rotatably supported on a support tube that extends behind the arm tilting means 24. It consists of a shaft 26, a pinion 28 fixed to this support shaft, a rack 30 that meshes with this pinion, and a cylinder 32 that moves this rack back and forth.
2 is supported by a movable frame 34.

Therefore, when the cylinder 32 is extended, the rack 30 advances and the receiver moves the arm 20 to the retracted position parallel to the movement path of the rectangular bar 18 and retracted to the side thereof, as shown by the solid line position in FIG. , conversely, when the cylinder 32 contracts, the rank 30 retreats and the receiver moves the arm 20 along the chain line in FIG.
As shown in the drawings and FIG. 4, it moves to an advanced position to receive the rectangular bar 18 at right angles to the path of movement of the rectangular bar 18.

As shown in FIG. 4, the arm tilting means 24 includes a support tube 36 that is attached to the movable frame 34 and rotatably supports the support shaft 26, and a horizontal rotation shaft 38 that locks the bracket 34a of the movable frame 34. and the cylinder 4 attached to the machine frame 40.
The arm 44, which is pivotally supported by the piston 42a of the cylinder 42, is keyed to the horizontal rotation shaft 38.

Therefore, when the cylinder 42 is extended, the horizontal rotation shaft 38 rotates counterclockwise in FIG. When the arm 20 is tilted about the axis of 38, the arm 20 moves to the tilted position (the chain line position in FIG. 2) where the rectangular bar 18 thereon slides to one side, and when the cylinder 42 contracts, the plurality of receivers moves the arm 20 to a horizontal position (solid line position in FIG. 2) to receive the rectangular bar 18.

As is clear from FIG. 3, all the supports of the horizontal rotation shaft 38 are commonly used for the arm 20, so only one cylinder 42 is required.

The device 10 of the present invention includes a lid 46 that receives a rectangular bar 18 that slides down from an arm 20 and raises and lowers the rectangular bar 18, a pusher 48 that pushes the rectangular bar 18 on the lifter, and a lifter. It further includes a pedestal 50 for receiving the rectangular bar 18 transferred from above 46.

As shown in FIGS. 2 to 4, the lifter 46 consists of a plurality of rocking plates 54 pivoted to the machine frame 40 at a fulcrum 52, and the left edge (material outlet edge) of the rocking plates is located near the artificial edge of the cradle 50, and this left edge has an extension 54a extending downward as shown in FIG.

A piston rod 58a of a cylinder 58, which is pivotally supported on the machine frame 40 at a fulcrum 56, is connected to the lower end of this extension 54a.

Therefore, when the piston rod 58a of the cylinder 58 is expanded or contracted, the left end edge of the swing plate 54 swings about the fulcrum 52 and moves downward or upward relative to the inlet end edge of the pedestal 50.

The pusher 48, as shown in FIGS. 2 and 3, consists of a plurality of pusher conveyors 62 spanned between sprockets 60, 60' and a pusher plate 64 attached to each pusher conveyor.

As shown in FIG. 4, the sprocket 60 is driven by a reversible motor 66 mounted on the machine frame 40 via a chain 68 to reciprocate the pusher conveyor 62 within a predetermined range.

When the pusher plate 64 slides down the rectangular bar 18 from the arm 20 at the retreated position of the pusher conveyor 62, as shown by the solid line in FIG.
Thereafter, as the pusher conveyor 62 moves forward, the rectangular bar 18 rises up to engage with the rear edge of the rectangular bar 18 on the lifter 46 as shown by the chain line in FIG. Press on 46.

In FIG. 3, reference numeral 70 is a guide that engages with the pusher plate 64 and guides the pusher plate.

In addition, the sprocket 60 is used for all pusher conveyors 6.
It has a common drive shaft 60a for the two motors, so only one motor 66 and one chain 68 are required.

As shown in FIGS. 2 to 4, the pedestal 50 is made up of a plurality of slat conveyors 74 that extend between sprockets 72 and 72', and the slat conveyors 74 are provided with a slat conveyor 74 that extends laterally on the upper surface of the slat conveyor 74. It has a stopper 76 that aligns and receives the stack of first rectangular bars.

As shown in FIG. 4, the sprockets 72 are connected to a common drive shaft 80 via a chain 7B, and this drive shaft is connected to a motor (not shown).

The drive shaft 80 is driven to drive the slat conveyor 74 by the width of the rectangular bar 18.

Next, to describe the operation of the apparatus of the present invention, as shown in FIG. Grip the tip and pull it out from the die 14 in the direction of the arrow.

Thereafter, the receiver is moved to the arm 20 by the arm rotation means 22.
is moved to the forward position, the chuck of the carriage 16 is removed, and the rectangular bar 18 is received on the arm 20.

Note) As the rectangular bar 18 is drawn, the receiver on the die 14 side may be moved to the forward position sequentially from the arm 20.

Next, Uke operates the arm tilting means 24 to cause Uke to move the arm 2.
0 to the inclined position as shown by the chain line in FIG. 2, and the receiver slides the rectangular bar 18 on the arm 20 onto the lifter 46.

At this time, the pusher plate 64 of the pusher 48 is retracted below the arm 20 as shown in FIG. 2, so the pusher plate 64 does not get in the way.

The tube then returns the arm 20 horizontally by its tilting means 24 and pushes the pusher 48 in a forward motion so that it is transferred onto the pedestal 50.

The lifter 46 is in the lowest position, and the pedestal 50 is initially in a position where the stopper 76 receives the first rectangular bar 18 as shown in FIG.
is pushed by the pusher 48 until it hits this stopper 76.

The pusher 46 and receiver then return the arm 20 to the retracted position, and the second rectangular bar 18 is aligned and stacked on top of the first rectangular bar 18 in the same motion as before, but this time the lifter 46 Since the rectangular bar 18 rises by the thickness of the rectangular bar 18, the rectangular bar 18 is smoothly transferred from the lid 46 onto the pedestal 50.

After stacking the three rectangular bars 18 in this manner to form the first stack, the slat conveyor 74 of the receiving stand 50 is moved to the left in FIG. 2 by the width of the rectangular bars 18, and the same operation as before is performed. Then, second, third, etc. stacks are formed.

The materials stacked in several rows are carried out on the pedestal 50 by a crane or the like.

In addition, in order to prevent the rectangular bar 18 from being damaged on the arm 20 and to improve its sliding, the receiver has a protective layer 20a made of elastic and smooth material such as nylon or Teflon (trade name) on the upper surface of the arm 20. (Fig. 4) is preferably provided.

According to the present invention, as described above, the rectangular bars are automatically stacked one after another, making it easy to work and work safely. Since the stacks are sequentially aligned and transferred onto the pedestal by the lifting and lowering of the pusher and the stopper on the pedestal, there is a practical advantage that the stacking is done in good alignment.
