Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a turning device that changes the direction of continuously conveyed articles by turning them by 90 degrees, and the present invention relates to a turning device that changes the direction of continuously conveyed articles by turning them by 90 degrees. It can also be applied to boxes.

[Conventional technology]

A rotating device that continuously conveys a conventional fixed-shaped sheet-like article using a chain conveyor or other conveying means, and uses a part of the conveying force to change the direction of the article by approximately 90 degrees, is used above the conveying means. A stopper is installed vertically so that it touches one side of the article, and the conveyed article hits this stopper and automatically rotates, or a part of the conveyance means is a turntable type, etc. There is.

[Problem that the invention seeks to solve]

However, with a system in which a stopper is provided above the conveyance means, it is difficult to completely turn the conveyed article by 90 degrees, and with a turntable type, the conveyance means is complicated, and furthermore, there is a limit to how high the speed can be increased. In the present invention, the structure is simplified so that even a relatively lightweight sheet-like article can accurately change direction.

[Structure of the invention]

As shown in the drawings, the present invention includes a conveyor line equipped with a sliding plate having at least an inclined rotating chute at a rotating position provided in the middle of the article conveyor line; It consists of a conveying means for conveying the article, and a stopper provided on the conveying line at the rotating position, and a part of the article conveyed on the sliding plate comes into contact with the stopper, and the conveying force by the conveying means is reduced. After applying a turning force to the article around the stopper, when the diagonal corner of the article is guided to the turning chute, further turning force is applied to accurately turn the desired angle and slightly below the top of the conveyor line. The device is made to fall, absorb its rotational energy, fall to a normal position in a stationary state, and then be transported further.

[Means for solving problems]

Next, the present invention will be explained based on the drawings. Reference numeral 1 denotes a conveyance line that supports sheet-like articles, boxes, etc., and whose upper surface is slidable.
is made up of two parallel sliding plates arranged in the conveying direction of the article and facing each other, and the top surfaces of the sliding plates are at the same height. The upper part of one or both of the sliding plates is bent or curved to expand outward to form the rotating chute part 2, and the lower part of each sliding plate is bent inward in the horizontal direction to form the bottom piece 3, facing each other. The bottom pieces 3, 3 of the sliding plates are made substantially horizontal, and the article to be conveyed after being rotated is further conveyed on these bottom pieces. The conveyed article G is supported on the top surfaces of two opposing sliding plates 3, that is, the top surface of the conveying line 1, and a conveying chain 4 is disposed along the conveying line on the inside or outside of the sliding plates.
Feed claws 5 are provided protruding at a fixed pitch, and by driving the chain 4, the feed claws 5 push the rear end of the article G to slide it on the conveyance line 1 and convey it. This feed pawl 5 pushes the rear end of the article supported on the top surface of the conveyor line 1, and also pushes the rear end of the article supported by dropping onto the bottom piece 3. Transport is possible no matter where it is supported. In addition, another chain 6 is disposed below between the opposing bottom pieces 3 and 3 so that the conveyance chain conveys the articles supported at the top surface of the conveyance line and the articles supported at the bottom separately. In some cases, feed pawls 7 protruding from the bottom pieces 6 at regular pitches are made to look between the bottom pieces 3, and the articles supported on the bottom pieces are conveyed by the feed pawls 7.

Reference numeral 8 denotes a stopper, which is installed vertically inside the sliding plate on either side of the conveyor line, and is brought into contact with one side end surface of the article that slides on the conveyor line 1 and is conveyed by the feed pawl. It is intended to change the direction of.

[Effect]

The article G placed horizontally between the top surfaces of the opposing sliding plates of the conveyance line 1 has its rear end connected to the feed claw 5.
It is pushed by the chain 4 and is slid on the conveyance line by the drive of the chain 4. When the article G reaches the stopper 8 position, one side of the article G hits the stopper 8, but when it is further pushed by the feed claw 5, the article G is given a turning force around the stopper 8 because the stopper 8 is fixed. Start turning.
At this time, the feed pawl 5 is provided to be able to swing freely in the backward direction relative to the chain 4, so when a predetermined torque is applied to the feed pawl, the feed pawl is tilted backward little by little, Just before the feed pawl comes off from the rear end of the article due to backward tilting of the pawl, the article is only supported by the top surface of the conveying line 1 at its corner on the opposite line. For this reason, a turning force is applied to the article by the feed pawl and the stopper, and due to the effect of the inertia, the diagonal corner of the article is rotated from the top surface of the conveyance line a little before or at the moment when the feed pawl comes off from the rear end of the article. I started moving on to part 2,
A further rotational force is applied to the inclined surface of this chute section, and the article G is accurately rotated 90 degrees and dropped from the top surface of the conveyance line to the bottom piece. Since the distance between the opposing sliding plates is predetermined by the width of the article, the article can be kept in an accurately rotated state. In addition, since the article is dropped from the top surface to the bottom piece of this conveyance line, the rotational energy given to the article is absorbed by the falling energy, and the article can be stopped at the normal position without positional deviation.
This is further conveyed by a feed claw 7.

〔Example〕

The embodiments shown in Figures 1 to 3 are such that articles are conveyed along a conveyance line using a chain with hooks (feeding claws), but the embodiments shown in Figures 4 and 5 are different. The article G is placed horizontally on parallel belt conveyors 9, 9, and is conveyed by the drive of the belt conveyors, and also conveyed by the belt conveyor 10 after turning. Another belt conveyor 10 is disposed slightly below between 9 and 9, and in this way the articles are supported and conveyed by these belt conveyors 9 and 10. As shown in FIG. 1, a sliding plate 11 having a rotating chute portion with an inclined upper portion is provided. At this time, sliding plate 1
The bottom piece 3 at the bottom of 1 is unnecessary, and a belt conveyor 10 is disposed in place of this bottom piece. The stopper 8 is vertically installed inside one of the sliding plates as shown in FIG. 1, so that the belt conveyor 9 is driven, and the stopper and the turning chute part are used to accurately turn the article to a desired angle. It is something that can be done.

〔Effect of the invention〕

According to the present invention, an article placed horizontally on the top surface between two opposing sliding plates is conveyed by sliding on the top surface of the sliding plates by a driven feed claw, When it comes into contact with a vertically installed stopper, a turning force is applied to the article around this stopper due to the feeding by this feed claw and the stopper, and the object is moved to the diagonally upper corner immediately before or at the moment when the turning force by the feed claw disappears. The corner part is guided to the inclined chute part, and is further given a turning force in the same direction, and when it falls inside the chute and moves onto the bottom piece, this rotational energy is absorbed, it comes to rest in the normal position, and accurate direction change is possible. This method has the advantage that even a sheet-like article having a simple structure and light weight can change direction at high speed.
