Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for changing the number of rows of moving material during its travel.

Until now, there has been no suitable device for arranging materials that are continuously supplied in series into double rows, and the materials are transferred to the orthogonal conveyor and transferred to a receiving conveyor or a ceiling prepared above it. The only option was to feed the plate from the side and retract the conveyor, or by means of a separate transfer device.

Normally, when materials are moved in a single row, when changing them to double rows and placing them on a small top plate, etc., doing so by hand may cause deformation of the materials, especially when the materials are shaped like a flat plate. In this case, it is very difficult to transfer it by hand, and a large transfer device is required for this purpose, which results in a large occupied area and is economically disadvantageous.

The apparatus according to the present invention is for changing the number of rows of supplied materials to a predetermined number and moving them in the same direction as the direction in which the supplied materials travel.

In particular, when automatically slicing bar-shaped materials with a cutter or the like and arranging them in double rows on a top plate, etc., by installing this device under the cutter, the material to be cut off can be directly sliced into rings. It is possible to do this automatically on multiple bars equipped with the device.

As described above, this device can be used not only when materials are supplied from the side, but also when supply conveyors are arranged in series, by dividing the rows of materials in the same direction into the planned number of rows. It is possible to increase and transfer, and these actions are performed using multiple simple bars that operate differently.
It is characterized by the fact that it occupies a small area.

Next, the present invention will be explained based on the drawings. 1a, 1b, 1c

Reference numeral 21 denotes a supply device that supplies materials in series as indicated by arrow g.

The mechanism of the device according to the present invention has been described above, and the operation of the device will now be explained.

A-J in Fig. 1 shows the operating steps of this device,
First, as shown in A, the material 1a on the outside of the row is transferred onto the vertical feed bar 4.

Next, as shown in B, the cross feed bar 3 rises as indicated by arrow a, and lifts the material 1a from the follower feed bar 4.

As shown in C, the cross-feeding bar 3 carrying the material 1a moves horizontally as shown by arrow b, and after reaching its limit point, the cross-feeding bar 3 descends as shown in arrow C, as shown in D. As a result, the material 1a is horizontally moved on the vertical feed bar 4 by the distance indicated by the arrow b.

Then, as shown in E, the transverse feed bar 3 moves backward in parallel as shown by the arrow d in order to horizontally move the subsequent material.

Then, as shown in F as in A, the subsequent material 1b
moves onto the vertical feed bar 4.

Next, as shown in G, similar to B, the transverse feed bar 3 rises, and at this time, simultaneously lifts up the material 1a that has been horizontally moved in the previous step and the subsequent material 1b as shown by arrow a.

The horizontal feed bar 3 carrying the materials 1a and 1b moves horizontally as shown by arrow b, as shown in H as in C, and then
Similarly to D, as shown in ■, move the horizontal feed bar 3 as shown by arrow C.
descends and transfers the materials 1a and 1b onto the vertical feed bar 4.

This results in two rows.

As shown in J, the outermost material 1 in the same row
c is transferred onto the vertical feed bar 4, and the number of columns finally becomes three.

At the same time, the vertical feed bar 4 rotates as shown by arrow e, and the three materials ia, lb, and ic in the same row are simultaneously transferred to a conveyor provided below or to a top plate, etc. The feed bar 3 moves back in parallel as shown by arrow d.

In the process described above, the materials that have been continuously supplied in one row from the supply devices 21 provided in series are rearranged into three rows, but the horizontal movement distance of the horizontal feed bar 3 is By adjusting the operating speed and the activation timing of the vertical feed bar 4, the number of rows can be changed freely. Next, the transmission mechanism of the present invention will be explained. What determines this is the cam follower 13 that is in contact with the cam plate 11 at its outer periphery.

That is, when the input shaft 12 is rotated by a drive mechanism (not shown), the cam plate 11 also starts rotating, and the cam plate 1
A cam follower 13 in contact with the outer periphery of the frame 1 is moved up and down according to its outer shape, and a shaft 5 provided on a frame 15 is guided to move up and down via a support rod 14 equipped with the cam follower 13.

A transverse bar 3 is passed through the shaft 5, and as a result, the transverse bar 3 performs an up-and-down movement.

In this case, due to the elongated hole 7 formed at the upper end of the swing arm 6, the vertical movement of the shaft 5 and the swing arm 6 can be smoothly operated without any hindrance.

As described above, the horizontal movement of the cross-feeding bar 3 is guided, and in parallel with this, the rotation of the cam follower 10 is guided, and the horizontal movement of the cross-feeding bar 3 is performed.

That is, as described above, as the cam plate 11 rotates, the cam follower 10 provided on the side surface of the cam plate 11 also begins to rotate.
Since the cam follower 10 is rotatably loosely fitted into the elongated hole 9, the swing arm 6 swings about the support shaft 8 while moving up and down within the cam follower 10.

As a result, the shaft 5 moves horizontally, and the transverse feed bar 3
horizontal movement is induced.

As described above, by the combination of the two movements, the transverse feed bar 3 is
It works by horizontally moving the supplied material and converting it into a predetermined number of rows.

In this mechanism, by changing the shape and rotational speed of the cam plate 11 and the mounting position of the cam follower 10, it is possible to change the movement of the transverse feed bar 3, and as a result, the number of rows can be freely determined. be able to.

When the horizontal feed bar 3 has been operated the scheduled number of times in this manner, the vertical feed bar 4 begins to operate.

The vertical feed bar 4 starts rotating via a belt 20 by a bar 19 that is linked to an input shaft 12 for guiding the rotation of the cam plate 11 and starts rotating by a drive mechanism (not shown). By connecting a plurality of belts, all the vertical feed bars 4 are rotated at the same time and at the same speed.

As a result of this rotational activation, the materials lined up in the same row are transferred onto the top plate 2 prepared below the device.

As described above, the device according to the present invention has a simple mechanism that enables
The number of rows of continuously supplied materials is changed to guide the materials in the same direction.
