Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a device for distributing articles continuously supplied in a single row in a plurality of rows and in a desired number of articles in each row. is there.

(Prior Art) Conventionally, as a typical device for distributing articles continuously supplied in a single row in several directions, there is one as shown in FIG. This device is for distributing similar articles according to the difference in weight, and the one shown is an example of three distribution. In the case of the apparatus shown in the same figure, the articles 01 conveyed in a single row are once transferred and placed on the transfer plate 03, weighed, and then transferred and placed on the slide plate 02 and transferred. . Slide plate
02 is for moving a slide bar 07 installed between conveyor chains (not shown) in the axial direction, and has a projection 08 on the lower surface, and the projections 08 are arranged in parallel on the lower surface of the conveyor chain. By engaging with the distribution rails 09a, 09b, and 09c, each slide plate 02 laterally moves toward a predetermined distribution row as the chain moves.

In this distribution, one distribution rail is selected from the plurality of distribution rails 09a, 09b, and 09c provided along a distribution path determined in advance by the weight difference of the conveyed article 01, and the distribution rail is selected. In order to engage the protrusion 08 with, for example, a rotation guide piece shown by 010 in the drawing is brought into contact with the protrusion 08 and rotated by the air cylinder 011. This distribution rail is selected by moving the slide plate 02 laterally by the operation of the rotation guide piece 010 as shown in the figure, and by selecting the necessary distribution rail as described in, for example, Japanese Utility Model Publication No. 56-38024. There is also one in which it is electromagnetically raised toward the entrance side of the slide plate to engage with the projection on the lower surface of the slide plate.

The articles sorted as described above move on the chain conveyor and are transferred to any of the discharge conveyors 06a, 06b, and 06c arranged in a plurality of rows in the same transport direction.
At this time, the article 01 is once placed on one of the transfer plates 04a, 04b, 04c before moving to the discharge conveyors 06a, 06b, 06c.

Due to the above structure, the articles are conveyed in the same direction for both supply and discharge, and since it is necessary to pass through the interrupted part in the middle, a transfer plate is arranged, and the shape of the conveyed article is unstable, or the conveying speed is increased. If it is attempted to raise the processing capacity by raising it, the conveyed product was likely to fall on the transfer board.

(Problems to be Solved by the Invention) As described above, in the conventional article sorting apparatus, there is an interrupted portion in the middle of conveyance, and the article has to pass through this interrupted portion once. However, the articles tend to fall over, which is particularly disadvantageous for the transportation of articles having an unstable shape, and there is a limit to the improvement of the processing capacity.

The present invention has been made in view of these points, and an object of the present invention is to provide an article allocating device that enables smooth indexing, grouping, sorting, and transporting of articles.

(Means for Solving Problems) Therefore, according to the present invention, the articles are aligned and conveyed in a line, and
A supply conveyor in which an indexing device that expands the interval between the articles is installed side by side, a distribution section conveyor partially overlapped with the supply conveyor and arranged in parallel, and across the supply conveyor and the distribution section conveyor. A grouping device that is arranged on the side part and that guides the articles from the side surface to perform grouping, and is arranged horizontally on the upper surface side of the grouping device and diagonally with the rear part facing the distribution part conveyor side. A pusher device formed of an endless chain that rotates in the flow direction of the article is provided, and a plurality of bars of a constant length are provided outwardly at a constant pitch in a predetermined range of the endless chain of the pusher device, A predetermined number of articles grouped by the grouping device by the bar are pushed out and distributed to the guide portion of each of the distribution section conveyors, which is a means for solving the problem. It is intended to.

(Operation) The group of articles supplied in a line is indexed one by one by the indexing device, and then the articles are grouped into a certain number by the grouping device. As a result, the distance between the articles in the same group becomes zero, and the distance between the groups becomes constant. The pusher portions of the plurality of pusher devices (A) and (B) have the same dimension as the claw spacing of the grouping device,
Push each group of articles into a given row.

For example, in the case of sorting in three rows, the pusher device (A) on the upstream side is driven once in good timing while the articles pass through three groups by the electric signal, and pushes the articles to a predetermined row. The downstream pusher device (B) is mechanically interlocked with the driving of the grouping device to alternately push out the remaining two groups into a predetermined row, so that the desired 3
It will be lined up.

When attempting to sort into two rows using this device, the pusher device (A) is kept stopped by an electric signal in a fixed position that does not interfere with the article. Further, since the entire circumference of the pusher device (B) is twice the group pitch of the grouping device, each group of articles is alternately pushed into a predetermined row. On the other hand, the groups that are not extruded alternately go straight ahead, and as a result, they are sorted into two rows.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

1 to 3 show an article dividing device according to an embodiment of the present invention. In the figure, 2 is a supply conveyor, 3 is an indexing device consisting of a screw conveyor provided along the side of the supply conveyor 2, 4 is a grouping device, 5 is a distribution unit conveyor, 6 is a pusher device (A), 7 is a pusher device (B). The distribution section conveyor 5 has a portion that partially overlaps with the supply conveyor 2 in sequence and is arranged adjacent to and parallel to each other.

As shown in FIG. 2, these conveyors are driven in the same direction by a drive device 9 via a sprocket, a bevel gear, a line shaft, and the like.

The supply conveyor 2 and the distribution conveyor 5 are ordinary conveyors, and the driving force of the driving device 9 drives the distribution conveyor 5 via a sprocket. Supply conveyor 2
Is increasing the conveyor speed via sprockets 14,13.

The indexing device 3 is provided upstream of the grouping device 4 and indexes the articles 1 that are continuously supplied one by one.
Since this indexing device 3 needs to be synchronized with the operation of the grouping device 4, it is driven via the line shaft 15, sprocket, spur gear, etc. of the same drive system as the grouping device 4 to index the articles 1 one by one. .

The grouping device 4 is composed of an endless belt already installed between three sprocket wheels, and claws 16 are attached to the entire circumference of the grouping device 4 at equal pitch intervals. The speed of the grouping device 4 is adjusted to a predetermined capacity, but the supply conveyor 2 that conveys the article 1
Is adjusted to the screw pitch of the indexing device 3, so the speed is increased compared to the grouping device 4. Due to such a speed relationship, the articles 1 indexed one by one in the indexing device 3 are braked by the claws 16 of the grouping device 4 and are, for example, formed into a group of eight closely attached articles 1 at equal pitches. The nail 16 successively processes a group of eight articles.

One of the pusher devices (A) 6 is the line shaft 15
It is driven via a bevel gear, chain, sprocket and the like. The speed is the same as that of the grouping device 4. The pusher device (A) 6 is electrically started and stopped via a clutch / brake 10. As for the stop position, the sensor 12 detects a position where the cap 19 of the pusher device (A) 6 described later does not come into contact with the article 1, and the brake is activated by the signal. The activation timing is also detected by the sensor 11 when the head cap 19 of the pusher device (A) 6, which will be described later, and the claw 16 of the grouping device 4 are synchronized, and the clutch is activated by the detection signal. The frequency of starting and stopping is
1 while the claws 16 of the grouping device 4 pass through 3 groups
After starting and stopping once, push out one group (8 pieces) to the guide 8A on the right side in the traveling direction. At this time, since the pusher device (A) 6 does not act on the remaining two groups, the group of the other articles 1 goes straight.

The pusher device (B) 7 installed in the next stage is driven by the line shaft 15 via a bevel gear or the like. The speed at this time is the same as that of the grouping device 4.

The upstream pusher device (A) 6 and the downstream pusher device (B) 7 have the same configuration. The structure will be described with reference to FIG. The same number as 2 groups of 16 nails.
The endless chain 17 rotates in the flow direction of the articles 1 and is arranged horizontally on the upper surface side of the grouping device 4 and obliquely with its rear part facing the distribution unit conveyor 5 side,
Bars 18 having a predetermined number of caps 19 are provided on the outer peripheral portion so as to project outward at equal pitches, and the mounting range of the bar 18 having the caps 19 is 1/2 of the total number of pitches of the chain 17. . That is, the number is the same as one group of the grouping device 4.

The positions of the caps 19 of the two pusher devices (A) and (B) have a predetermined phase difference between them. Due to such a structure, in the pusher device (B) 7 on the downstream side, eight groups of the articles 1 aligned with the claws 16 of the grouping device 4 are alternately pushed out to the guide 8B on the right side in the traveling direction. However, the article group extruded by the upstream pusher device (A) 6 is in a state where there is no article once in three groups. With such a structure and operation, the guides 8A, 8
The same number of articles 1 will be distributed to B and 8C.

(Effect of the Invention) As described above in detail, according to the present invention, when the article is transferred to the next carrying path, it is obliquely transferred to the conveyor moving in the same direction and at substantially the same speed. Therefore, it is possible to transfer goods very smoothly,
It is possible to eliminate the inconvenience that the articles fall over when they are transferred to the next rank, and it is possible to ensure the sorting of the articles and speed up the work. Further, in the pusher device according to the present invention, since the bar having a constant length attached at equal pitch is provided in a predetermined range of the endless chain, the pusher device serves as a guide for a limited time. Moreover, since the product rotates in the direction of the flow of the article, the article can be smoothly pushed onto the sorting section conveyor and sorted so as not to fall. In addition, since the structure is simple, maintenance is easy. Furthermore, since the feed conveyor is provided with an indexing device that widens the space between the articles, the articles are damaged when the articles are grouped from the side by the grouping device. It has advantages such as no fear.
