Description

  The present invention relates to an aligning and conveying apparatus capable of aligning and conveying articles such as stick-shaped snacks and putting them in a tray or the like.

For example, stick-shaped dry sausages, beef jerky, or stick-shaped snacks (hereinafter referred to as “articles”) sandwiched between white fish and cheese are sold in a lined bag. The packaged goods are aligned by an aligning / conveying device before packaging, then transferred to a tray and carried into a packaging line.
As such an aligning and conveying apparatus, the one described in Patent Document 1 is known. The invention of this Patent Document 1 arranges a large amount of small fish into a tray and provides a plurality of partition walls extending in the sliding direction on a chute for sliding the small fish to form a plurality of conveyance paths, Each partition wall is formed so as to go downstream. According to this, even if a small fish is thrown across the plurality of conveyance paths on the upstream side of the chute, the direction is changed and aligned by each partition wall in the course of sliding down.

Japanese Patent No. 3076728

However, in place of such a sliding chute, even if it is conveyed by a vibrating conveyor, many items such as snacks are light and thin, and such items are put into a vibrating conveyor with a plurality of partition walls. However, in many cases, articles are entangled and are not conveyed in alignment. In addition, it is difficult to stack the articles in an aligned state at the front end of the vibration conveyor and then discharge them to the tray.
The present invention provides a new aligning and conveying apparatus capable of aligning and conveying stick-shaped articles on a vibrating conveyor without requiring such intervention, and capable of stacking stick-shaped articles on the front end of the conveyor. The task is to do.

  In the aligned conveying device according to the present invention, a plurality of conveying paths formed by a plurality of partition walls extending in the conveying direction are formed on the conveying surface of the vibration conveyor, and a plurality of stick-like shapes that are input to the starting end side of each conveying path. An alignment transport device that transports articles along each transport path and aligns them side by side in front of the shutter at the front end of the conveyor, and turns the stick-shaped articles lying across the plurality of transport paths to the partition wall in the transport direction. An uprising part is provided, and an inclined part that is inclined upward in the conveying direction is provided in each conveying path downstream thereof, and the article is stacked at a stepped part between the inclined part and the shutter. It is characterized by.

Because of this structure, even if the stick-shaped article thrown into the starting end of each conveyance path is thrown in a posture that crosses a plurality of conveyance paths, the rising part of the partition wall during conveyance Since the direction is changed, the article falls on one of the conveyance paths. Then, the articles that have fallen on each conveyance path are conveyed by the vibration of the vibration conveyer, get over the inclined portion on the downstream side, fall to the step portion in front of the shutter, and are aligned side by side. In this way, the subsequent articles also go over the inclined part one after another. At that time, the subsequent article goes over the inclined part while lifting the head above the stepped part. The article goes over the preceding article aligned at the step.
Instead of this configuration, for example, if the inclined portion is eliminated and flattened, and a step portion for stacking articles is formed at a position one step lower than the flat surface, the preceding article that has fallen on the step portion is stacked at the step portion. As it is done, subsequent articles are blocked by the trailing edge of the stacked articles and can no longer advance. In contrast, in the present invention, for example, even if the article is laminated so that the article overflows at the stepped part, the subsequent article goes over the inclined part while lifting the head over it, and the preceding article of the stepped part is left as it is. Therefore, the subsequent article is not obstructed by the preceding article in which the step portions are stacked.
In addition, if the height of the partition wall of the step portion is set to the average height of the articles stacked there, for example, even if the articles are stacked at a height exceeding the partition wall, the partition wall exceeds the partition wall. The articles slide down due to the vibration of the conveyor and fall to the adjacent conveyance path, so that the loading amount of each conveyance path can be leveled.

According to the present invention, even stick-shaped articles such as snacks that are easily entangled can be reliably conveyed in an aligned manner through a plurality of conveyance paths.
In addition, since the articles conveyed in each conveyance path can be reliably stacked and aligned before the shutter, the aligned state can be maintained even if they are transferred to the tray. Therefore, until now, the articles stored in the tray have been aligned by hand, but the labor can be saved by omitting such labor.

The perspective view of one Embodiment of the alignment conveyance apparatus which concerns on this invention The perspective view in which the stick-shaped article | item was thrown into the starting end part of the said alignment conveyance apparatus. Perspective view of the article in transit Perspective view when the article is over the slope Perspective view when articles accumulated in the stepped portion are discharged

  Hereinafter, an embodiment of an alignment transport apparatus according to the present invention will be described with reference to the drawings.

  FIG. 1 shows a perspective view of an embodiment of an alignment transport apparatus according to the present invention. In this figure, the aligning and conveying apparatus 1 is configured as an oscillating conveyor 2 that conveys an article G (see FIGS. 2 to 5) in the direction of arrow A with an electromagnetic feeder (not shown). A plurality of partition walls 3 extending in the transport direction A are provided at equal intervals on the transport surface of the vibration conveyor 2, and a plurality of transport paths 4 are formed by the adjacent partition walls 3 and 3.

  In each partition wall 3, a part of the partition wall 3 closer to the center is formed with a rising portion 31 raised from its upper edge. The start-up unit 31 turns an article G that has been placed so as to lie on the plurality of transport paths 4 in the transport direction A. For this reason, the rising portions 31 are formed at appropriate intervals at which the article G can change direction. In addition, an inclined portion 5 that is inclined upward in the conveying direction A is formed on the downstream side of each conveying path 4. Between the inclined portion 5 and the shutter 6 at the front end of the conveyor is slightly longer than the length of each article G. A long step portion 7 is formed, and the articles G are stacked and aligned at the step portion 7.

  Each partition wall 3 of the stepped portion 7 is formed at an average height of articles G stacked on each conveyance path 4. Thereby, even if the loading amount of each conveyance path 4 of the stepped portion 7 exceeds the height of the partition wall 3, the overflowing article G falls to the adjacent conveyance path 4 due to the vibration of the conveyor 2 and is averaged. .

The shutter 6 is disposed at the front end of the conveyor 2, and the article G that has reached the stepped portion 7 in front of the shutter 6 is aligned with the head aligned by the forward movement by the conveyor 2 and the blocking action by the shutter 6. It is done.
Note that the shutter 6 is configured to move up and down at the timing when the tray 8 shown in FIG.

Next, the operation of the alignment transport device 1 will be described.
The article G weighed to a constant mass by an automatic weighing device (not shown) is fed to the starting end side of the vibrating conveyor 2 as shown in FIG. Then, a part of the articles G that have been thrown down are transported by dropping onto the transport path 4, and the other articles G are transported across the plurality of transport paths 4. Even when the article G in such a lateral direction comes into contact with the rising portion 31, the article G gradually changes its direction in the transport direction A with the contact position as an axis. In this way, each article G falls on the nearest conveyance path 4 and is conveyed downstream (see FIGS. 2 and 3).

Each article G that reaches the downstream side climbs the inclined portion 5, rides over the inclined portion 5, and falls to the stepped portion 7. At that time, as shown in FIG. 4, the succeeding article G climbs over the inclined portion 5 while lifting the head above the stepped portion 7, so even if the preceding article G is stacked at the stepped portion 7, The vehicle goes over the inclined portion 5 without being obstructed by the preceding article G and rides on the preceding article G in the stepped portion 7.
When all the articles G are thus aligned at the stepped portion 7, the shutter 6 is opened and transferred to the tray 8 waiting in front of it by the vibration of the conveyor 2 (see FIG. 5). In this way, a series of cycles are repeated, and the articles G arranged in the tray 8 to be conveyed one after another are loaded.
The tray 8 is sequentially transported in a direction orthogonal to the transport direction A.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to this, A various aspect is employable. For example, instead of the conveyor 2 constituted by an electromagnetic feeder, a so-called fast-back type conveyor that performs a reciprocating motion in which the forward movement is low speed and the backward movement is high speed may be used. Further, the rising portion 31 may be a pin. Furthermore, in this embodiment, the partition wall 3 of the stepped portion 7 has the same height as the partition wall 3 of the upstream conveyance path 4, but the partition wall 3 of the stepped portion 7 is lower and the partition wall 3 of the transport path 4. May be formed higher.
