Abstract

PURPOSE:To straighten a material to be conveyed preventing the material from changing the center of its flow line, by providing a sorting conveyer, whose point end part can move and stop in plural positions in the vertical direction, while a multi-staged shift conveyer which can horizontally move in a direction crossing at a right angle with the conveying direction of the material corresponding to said plural stop positions. CONSTITUTION:A strip-shaped material (a) is carried forming one line successively by a feed conveyer 10, and the first material a1 is conveyed to an upper stage shift conveyer 30a by a sorting conveyer 20 whose point end is lifted by cylinders 21a, 21b. The shift conveyer 30a is shifted to either right or left by a cylinder 34, and the material a1 is stopped in a position, where its point end shields light of a phototube P5, via a guide means 40. Similarly the next materials a2, a3 are placed on intermediate and bottom stage shift conveyers 30b, 30c via the sorting conveyer 20, and the bottom stage conveyer 30c is shifted to either right or left. Under this condition, the material, whose position is respectively determined by phototubes P1-P6, is straightened joining on a confluent straightening conveyer 50 and fed into the conveyer 60 in the next process.

a.

A sorting conveyor 20 whose tip end can move and stop at a plurality of positions in the vertical direction is disposed via a conveyor 21b, and the conveyor 20 is perpendicular to the conveyance direction of the strip-shaped material a corresponding to the plurality of stopping positions of the tip of the sorting conveyor 20. A multistage (three stages in this embodiment) shift conveyor 30 that can be horizontally moved in the direction shown in FIG.

This shift conveyor 30 shifts the strip-shaped materials a distributed by the sorting conveyor 20 by a certain amount in a direction perpendicular to the direction of movement, or temporarily puts them on standby.

Further, at the discharge end of the shift conveyor 30, the strip material a is arranged to merge and align the strip materials a on the shift conveyor 30 and the guide means 40.

A guide such as a standby conveyor is provided with a merging alignment conveyor 50, and between the merging alignment conveyor 50 and the tip of the shift conveyor 30, transfers the band-shaped material a onto the merging alignment conveyor 50 in an aligned state. Means 40 is installed.

Further, 60 is a next process conveyor that conveys the aligned strip material a to the next process.

Next, each of the above configurations will be explained in more detail.

The feed conveyor 10 is a normal belt conveyor and is driven at all times, and the sorting conveyor 20 has its head pulley side in order to convey the strip material a to each stage of the next multi-stage shift conveyor 30. Lifting means 21a, 21b such as air cylinders are provided for moving up and down, and are constantly driven.

Further, FIG. 3 shows a front view of the multi-stage shift conveyor 30, and shows the conveyor 3 of each stage of the multi-stage shift conveyor 30.
0a, 30b, and 30c are slidably attached to a slide rail 32 fixed to a pedestal 31 via a slide block 33.

In addition, the upper and lower shift conveyors 30a and 30C have
Slide rail 3 in the direction perpendicular to the direction of conveyor movement.
An air cylinder 34.35 is provided for shifting the air cylinder 34.35, the proximal end of which is fixed to the frame 31, and its piston rod fixedly mounted on the conveyor frame 31. There is.

Also, since the middle shift conveyor 30b does not require a slide,
It is fixed onto the slide rail 32 via a fixing fitting 37 at the center of the pedestal 31.

Further, the guide means 40 shifts the upper stage to the shift conveyor 30a.
When the conveyor is shifted, the center of the conveyor is fixed at the same position, and an auxiliary roller 41 is provided at the tip.

The merging alignment conveyor 50 is the middle shift conveyor 30b.
And from the position where the lower stage shift conveyor 30c has shifted and from any conveyor of the guide means 40, the strip material a
The conveyor is wide so that the receiver can be removed.

Further, an auxiliary roller 42 is fixed to the tip of the middle shift conveyor 30b. At the transfer section between the sorting conveyor 20 and the shift conveyor 30, there are a phototube P1° for detecting passage of the strip material a, an upper shift conveyor 30a, a middle shift conveyor 30b, and a lower shift conveyor 30.
c and the tip of the guide means 40, respectively, are phototubes P2. P3゜P4. P5 is provided.

Also, below the guide means 40 is a middle shift conveyor 30.
The band-shaped materials 32r a3 sent from the b5 lower stage shift conveyor 30c are aligned and merged to the alignment and merge conveyor 50.
A phototube P6 is provided to detect when the upper fixed position has been reached.

Next, a method for aligning and conveying the strip material a will be explained with reference to FIGS. 5 to 8.

First, a belt-shaped material a of a certain size is produced by a belt-shaped material manufacturing device.
When the feed conveyor 10 sequentially supplies the single-port strip material a1, the cylinders 21a and 21b of the sorting conveyor 20 operate, the upper shift conveyor 30a starts driving, and the strip material a□ is conveyed to the upper shift conveyor 30a (see FIG. 6(a)), and when its tip blocks the light from the phototube P2, the upper shift conveyor 302 is temporarily stopped, and the cylinder 34 is immediately activated and shifted, and after the shift is completed, the shift conveyor 30a and The guide means 40 is synchronously driven so that the tip of the strip material a is aligned with the phototube P5.
feed until the light is blocked.

When the rear end of the strip-shaped material a1 passes the phototube P1, the rod of the cylinder 21a is retracted to wait so that the next strip-shaped material a2 can be transferred to the middle shift conveyor 30b, and the middle shift conveyor 30b starts driving. When the rear end of the strip material a passes the phototube P2, the upper shift conveyor 30a stops, and the cylinder 35 is activated to return to the original material receiving position and wait.

The strip material a2 passes through the sorting conveyor 20 and enters the middle shift conveyor 30b, and when the tip of the strip material a2 blocks the light from the phototube P3, the middle shift conveyor 30b is stopped, and the middle shift conveyor 30b is on standby at that position. (See figure (b))
.

When the rear end of the strip material a2 passes the phototube P1, the cylinder 21b is activated, the sorting conveyor 20 moves to a position where it connects with the sorting conveyor 30c, and the lower shift conveyor 30c starts driving.

Next, the strip material a3 passes through the sorting conveyor 20 and is conveyed to the lower shift conveyor 30c, and when the tip thereof blocks the light from the phototube P4, the lower shift conveyor 30c is stopped, the cylinder 34 is activated, and the conveyor is shifted. . When the rear end of the strip-shaped material a passes the phototube P1, the sorting conveyor 20 moves to a position where it connects with the upper shift conveyor 30a by the operation of the cylinders 212 and 21b, and the upper shift conveyor 30a starts driving. (See C1).

When the lower stage shift conveyor 30c completes its shift, the middle stage shift conveyor 30b, the lower stage shift conveyor 30c, and the merging alignment conveyor 50 are simultaneously driven to remove the strip material a2.
and a3 are merged and aligned on the merge alignment conveyor 50, and when the tip of the strip material a2 blocks the light from the phototube P6, the guide means 40 is driven, and the strip material a is placed on the merge alignment conveyor 50 on top of the strip materials a2+a3. The strip-shaped material a1 + aZ +
83 in an aligned state (see FIGS. 7 and 8). The middle shift conveyor 30b stops when the rear end of the strip material a2 passes the phototube P3. Also material 30
When the rear end of the conveyor c passes the phototube P4, the lower shift conveyor 30c stops and simultaneously returns to the material receiving position by actuation of the cylinder 34 and waits.

By repeating the above operations, the strip materials ai, az, a,, etc., which are supplied one after another, are next aligned on the merging alignment conveyor 50 as shown in Fig. 4+a) and Fig. 4(b). Sent to the process's loading equipment.

The steps T and δ of the strip material a in FIG. 4 are the cylinder 34.
．． Determined by 35 strokes, α.

β is determined by the mounting positions of phototubes P3 and P4 and P5 and P6. Stroke of cylinder 34.35, photocell P3. P4. P5. By adjusting the pick-up/row position of P6, a free alignment state can be formed.
