2. Description of the Related Art Aligning conveyors are used in which symmetrical left and right skew conveyors are paired and the articles are sent to the center line side between the conveyors and conveyed while being aligned. It is necessary to increase the conveyor length in order to fully align the articles. Also, connecting a large number of merging ports to the conveyor increases the conveyor layout and the distance required for alignment. Then, it becomes necessary to curve the alignment conveyor. When the conveyor is curved, it is common sense to connect the conveyor units with a predetermined curvature so that the conveyor conveying direction changes smoothly. In addition, it is common sense to use a roller or the like having a small diameter inside the conical curve and a large diameter outside the curved portion. If this is done, dead space will occur at the curve. Further, in the curved portion, for example, a mere roller conveyor is used instead of the skew conveyor for sending the articles to the center line, and there is no alignment action. In this way, the curved portion has a dead space and has a wasteful length with no alignment effect.

SUMMARY OF THE INVENTION It is an object of the present invention to arrange an aligning conveyor at approximately right angles or at approximately one, with virtually no dead space.
The direction is changed by 80 ° and the aligning action can be obtained even at the direction changing portion (claims 1 to 3). An additional object of the inventions of claims 2 and 3 is to make the direction change of the article smoother.

According to the present invention, the pair of oblique conveyors on the downstream side is connected to the pair of oblique conveyors on the upstream side at a substantially right angle to form the direction changing section. The articles conveyed from the upstream side enter the skew conveyor on the downstream side, and the skew conveyor is also used at the direction changing portion, so that the articles can be aligned. Also, since the downstream side is a skew conveyor, the articles that enter the downstream side will be moved toward the center line side, the articles will spread over the entire surface along the width direction of the downstream side conveyor, and the alignment effect up to that point will be canceled. There is no. Further, since the upstream side and the downstream side can be connected to each other at a substantially right angle, the radius of curvature of the turning portion becomes almost 0, and the dead space in the turning portion can be almost eliminated. Further, if the direction changing section performs two substantially right-angled direction changes twice, a U-turn can be formed without a dead space (claim 1).

According to the second aspect of the present invention, since the direction-changing portion is configured so that the upstream-side skew conveyor is difficult to be inserted into the downstream-side skew conveyor, the article conveyed from the upstream side can be conveyed to the downstream-side diagonal conveyor. Immediately move to near the center line of a pair of row conveyors. Also, at the boundary from the upstream side to the downstream side, since the conveying direction of the article suddenly changes, it is conceivable that the article may take a locus that deviates largely from the center line on the skew conveyor on the downstream side. Since the skew conveyor on the downstream side is tightly packed, the locus of the articles on the downstream side does not greatly deviate from the center line. For this reason, it is possible to enhance the aligning action of the articles at the direction changing section and to smoothly move the articles at the direction changing section.

According to the third aspect of the present invention, the guide roller is provided inside the direction changing portion at the boundary between the upstream-side skew conveyor and the downstream-side skew conveyor. With the movement from the upstream side to the downstream side, if the trajectory of the article deviates largely from the center line and tries to protrude inside the direction changing portion, it comes into contact with the guide roller and is returned to the center line side. Therefore, it is possible to smoothly change the direction from the upstream side to the downstream side.

Reference numeral 16 is a drive belt of each skew conveyor, and each of the skew conveyors 10 and 11 is a power roller conveyor having a horizontal surface, and the rollers are rotated by the drive belt 16 so as to be substantially along the drive belt 16. The article in the opposite direction. This direction is a direction in which the article is sent to the center line side of the boundary between the skew conveyors 10 and 11, and the speeds of the skew conveyors 10 and 11 are different between the left and right.
Therefore, the articles on the skew conveyor on the high-conveyance speed side are
It is extruded at a high speed over the center line onto the skew conveyor on the opposite side, which has a lower conveyance speed, and then in the opposite direction at a slightly lower speed over the center line. For this reason, the article meanders in a complicated manner in the center line portion between the skew conveyors 10 and 11, and in the meantime, turns and turns frequently.
As a result, the piles of the articles are eliminated, and the articles are arranged in almost one row.

The operation of the direction changing portion in the embodiment is shown in FIGS.
Shown in. The movement of the article 20 indicated by a circle in FIG. 2 is the movement of the article in a normal case, and the article 20 is the skew conveyor 10p, 11
From near the center line between p, skew conveyor 11q
To the center line between the skew conveyors 11q and 10q by inertia due to the motion in the left matrix 4 and the skew motion in the skew conveyor 11q. Article 2 here
Since 0 moves to the skew conveyor 11q from the position where it has entered the skew conveyor 11q, it quickly reaches the center line. Next, the skew conveyer 11r moves from a position where the skew conveyer 11r is not tight to the skew conveyer 11r, so that the skew conveyer 11r similarly enters the center line of the skew conveyers 10r and 11r. Align by action.

As shown in FIG. 2, since the article 20 moves to the downstream side at the position where the skew conveyors 11q and 11r on the downstream side are tightly packed, the distance to reach the center line to the downstream side becomes short, Even on the downstream side of the direction changing portion, the aligning action can be obtained more quickly. Also, since it reaches the centerline almost immediately when transferring to the downstream side, it is unlikely that the article will be greatly deviated from the centerline on the downstream side,
The operation becomes stable. Further, when there are articles that have been gathered and conveyed in a dumpling manner on the skew conveyor on the upstream side, the positions of these articles entering the skew conveyor on the downstream side (positions along the conveying direction on the downstream side) are different. Therefore, the dumpling-shaped articles are easily aligned on the downstream side. This situation
FIG. 3 schematically shows the articles 25 and 26 as an example.

The article 22 shown in FIG. 2 largely protrudes from the center line for some reason. It should be noted that such articles hardly occur when the upstream-side skew conveyor is difficult to be inserted into the downstream-side skew conveyor as in the embodiment. By the way, there is a portion where the three types of regions of the left matrix 4, the orthogonal portion 8 and the right matrix 6 are in contact with each other. Guide roller 1 on this part
4 is provided. If the guide roller 14 is not provided, if the article 22 is temporarily placed on the contact points of the three regions,
This article receives a force in the direction indicated by the black arrow in the figure from the three types of skew conveyors and rotates about the boundary point of the three regions. This situation is shown in FIG. In this way, once the article enters the boundary points of the three regions, it becomes difficult to get out of it, and the operation becomes unstable. Therefore, in order to prevent articles from entering the boundary points of the three areas, the guide roller 1
4 is provided.

FIG. 4 shows the overall structure of the aligning conveyor 2 of the embodiment. The merging conveyor 24 is provided in the left matrix 4 and the right matrix 6.
Are connected to appropriate places, and the articles that have been introduced from the respective merge ports 24 and the articles that originally flow on the alignment conveyor 2 collide in the vicinity of the center line between the left and right skew conveyors, Due to the complicated meandering motion, they are pushed away from each other, aligned in a line, and transported. As is clear from FIG. 4, the left matrix 4 is orthogonal to the orthogonal portion 8 at a right angle of 90 °.
When the direction is changed and the direction is changed to the right matrix 6 again at a right angle of 90 °, there is no dead space associated with the direction change. Then, the alignment operation of the articles can be continued while the direction is changed from the left matrix 4 to the right matrix 6.

FIG. 5 shows a modified alignment conveyor 32.
In the embodiment, it is difficult to insert the upstream skew conveyor into the downstream skew conveyor because the locus is largely deviated from the downstream center line, the inside of the turning portion, especially the left matrix and the right matrix and the orthogonal portion. This was to prevent an article from entering the boundary between the three areas. Another significance of providing the bite was to make the article reach the vicinity of the center line quickly on the downstream side and to smooth the flow of the article on the downstream side. Of these, the guide roller 14 may be provided as long as the article is prevented from entering the boundary between the left matrix, the right matrix, and the orthogonal portion. In FIG. 5, 34 is a new left matrix, 36 is a new right matrix, 38 is a new orthogonal portion, and the guide roller 14 is provided at the boundary between them. The connection between the upstream side and the downstream side here is common to the embodiment in that the upstream side and the downstream side are connected to each other at a substantially right angle to make a U-turn, but the downstream side hardened portion is not provided. Different from the example.

In the embodiment, the direction of the article is changed to U
Made it turn. However, in some cases it may be desired to simply change the orientation of the article by 90 °. FIG. 6 shows an alignment conveyor 52 suitable for this. Upstream skew conveyor 10p,
Reference numeral 11p denotes a connecting portion with the downstream-side skew conveyors 10q and 11q, which is tightly inserted into the oblique conveyor 11q side, and 12 is a biting portion. By doing so, the article 40 is transferred from the upstream side to the downstream side near the center line of the skew conveyor 11q on the downstream side and is quickly transported to the vicinity of the center line between the skew conveyors 10q, 11q on the downstream side.
Then, the flow of the article does not largely deviate from the center line on the downstream side, and the flow of the article on the downstream side becomes smooth. In the case where the temporary hard-to-buy portion 12 is not provided, for example, when there is an article 41 that has moved near the side end of the skew conveyor 11p on the upstream side, when the article 41 transfers to the downstream side, the direction is rapidly changed. As shown in the figure, it may fall inside the direction changing part. On the other hand, bite part 1
Providing 2 makes the locus of the article in the direction changing section smoother, and eliminates the possibility of a large protrusion or drop inside the direction changing section. As a precaution, a guide roller may be provided on the inner boundary of the direction changing portion.

As described by comparing the embodiment shown in FIGS. 1 to 4 with the modification shown in FIG. 5, when the guide roller 14 is provided inside the turning portion, the articles fall inside the turning portion. Etc. can be prevented. Such an example is shown in FIG. Reference numeral 62 denotes a new aligning conveyor, which is a boundary portion between the upstream-side skew conveyor and the downstream-side skew conveyor, and the guide roller 14 is provided at a corner inside the direction changing portion.
