Abstract

PURPOSE:To surely feed articles at a correct attitude from a feeding conveyor to a main conveyor by dividing a plurality of thin strip shaped conveyors arranged in the driving direction into plural groups in the direction crossing with the driving direction and driving the contiguously arranged group at an equal speed, while at each different speed in the driving direction. CONSTITUTION:A feeding conveyor 2 is constituted by arranging a plurality of thin strip shaped belt conveyors 22, 23,... which are parallel in the driving direction. Each conveyor 22, 23,... is divided into different length striding over in each group A, B, C, and since, when an article G is transported in the width direction, the terminal position of each conveyor 22, 23,... is different in each group, and the driving speed is different in each group, a turning torque is generated on the article G because of the relative position between the conveyors 22, 23,... and the article G and the speed difference between the groups, and the article is transferred on a main conveyor, keeping the attitude in a previously determined direction. Accordingly, the article is prevented from being broken and damaged, and transfer precision is improved and workability is improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for reliably supplying an article from a supply conveyor to a main conveyor for conveyance while maintaining its posture.

[0002]

2. Description of the Related Art When articles are supplied from a side to a driven main conveyor, the supply conveyor is driven at a predetermined constant speed and at a speed corresponding to the traveling speed of the main conveyor. The product is automatically supplied to the main conveyor. An article supply apparatus using this conveyor is shown in FIG.

[0003]

When articles are loaded into the main conveyor at the same speed with no speed change in the width direction of the supply conveyor, if the conveying speed is higher than the loading speed, the width of the main conveyor is sufficiently large. If it is not widened, the input articles may overrun due to the energy of the articles and fall from the main conveyor, or may collide with guides arranged along the main conveyor and damage the articles. On the other hand, if the feeding speed is slow, the posture of the article fed onto the main conveyor changes, and the article cannot be fed while maintaining the correct posture.

It is an object of the present invention to maintain a correct attitude from the supply conveyor to the main conveyor so as to surely supply the material.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above-mentioned object, and the supply conveyor is arranged so as to abut on the main conveyor at a predetermined angle. At least its tip is configured by arranging a plurality of strip-shaped conveyors parallel to the driving direction, and each strip-shaped conveyor is divided into a plurality of in the direction intersecting the driving direction, each strip-shaped conveyor group disposed adjacent to each other. The gist is to control the direction of the transferred article by driving at a constant speed and at a different speed with respect to the driving direction.

[0006]

A supply conveyor whose front end is in contact with the main conveyor at a predetermined angle is arranged on the side surface of the main conveyor, and the supply conveyor is provided with a plurality of strip belts parallel to the driving direction. A plurality of strip-shaped conveyors are arranged in parallel with the drive direction, and each strip-shaped belt is divided into a plurality in the drive direction, and the strip-shaped conveyors are adjacent to each other. The group is driven at a constant speed and at a different speed in the driving direction. As a result, when articles are conveyed on the supply conveyor, rotational torque is generated sequentially due to the speed difference during transfer of the strip-shaped conveyor groups in the order of the conveyance direction, and the posture of the articles is controlled to ensure reliable and accurate transfer onto the main conveyor. It is often reprinted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The article supply apparatus of the present invention will be described below with reference to the illustrated embodiments. In the figure, 1 is a main conveyor that conveys articles, which is appropriately used by connecting trays and operating at a predetermined speed.
The structure of this main conveyor is not limited.

The main conveyor 1 is arranged so that the tip of the supply conveyor 2 is in contact with the side surface of the main conveyor 1. The supply conveyor 2 is configured by arranging a plurality of belt-shaped belt conveyors 21, 22 and 23, which are parallel to the driving direction, at the leading end of a conveyor body 20 made of a belt or a roller conveyor. 2 is contacted to the side surface of the main conveyor 1 at a predetermined angle with respect to the main conveyor 1. And each of these belt conveyors 21, 22,
As shown in FIGS. 1 and 2, 23 is divided into a plurality of parts before and after the driving direction, and each of the conveyors 2
1, 2, 22 and 23 are each a strip-shaped conveyor group on the base end side, a group A is a central conveyor group, and a main conveyor 1
The conveyor group on the side in contact with is the group C, and the lengths of the conveyors 21, 22, and 23 of the groups A, B, and C are equal or different, and further, each group of the conveyors is driven at a constant speed. However, the conveyor groups that are adjacent to each other in the transport direction are driven at a constant speed.

In the embodiment of FIG. 1, each conveyor 21, 22, 22
The lengths of the groups of 23 are different, and when the articles G are conveyed on the supply conveyor 2 by this, the end positions of the conveyors 21, 22, and 23 of the group A are different, so that Even if the short conveyor 23 finishes on the conveyor and the bottom surface of the article moves to the next group B conveyor 23, the bottom surface on the other side of the article is on the long conveyor group A. Since the A group conveyor is driven at a higher speed than the B group conveyor, a turning torque is generated in the article due to the speed difference between the A groups and the B groups of the conveyors 21 and 23, whereby the article swivels on the conveyor. Similarly, from B group conveyor to C
The same turning occurs when transferring to the group conveyor, and further when transferring from the group C conveyor to the main conveyor 1, and the article is transferred while being held on the main conveyor in a predetermined posture. Is.

In the embodiment shown in FIG. 1, the conveyors 21 and 21 of the A group
2 and 23 are all equally high-speed driven, but have different lengths, the conveyors of the B group are all the same length, are all driven at the same medium speed, and the conveyors 21, 22 and 2 of the C group are all driven.
3 has different lengths, but is driven at a constant speed and at a lower speed than the group B. It can also be arranged and driven in the opposite direction.

In the embodiment shown in FIG. 2, the lengths of the conveyors 21, 22 and 23 are the same in both the A group and the B group, only the C group has an unequal length, and the driving speed is sequentially changed from the A group to the B group and the C group. It is meant to be fast. And each conveyor 21 of each group,
By changing the frictional resistance of 22 and 23, a turning torque is generated in the conveyed article by the change of the slip generated on the bottom surface of the article, the article is rotated, and the posture is controlled.

[0012]

The article supply apparatus of the present invention is arranged in such a manner that the supply conveyor is in contact with the main conveyor at a predetermined angle, and the supply conveyor is a strip-shaped conveyor having at least its tip parallel to the driving direction. Is configured by arranging a plurality of, and each strip-shaped conveyor is divided into a plurality in a direction intersecting the driving direction, respectively, the strip-shaped conveyor groups adjacently arranged respectively at a constant speed, at a different speed in the driving direction. Since it is driven and configured to control the direction of the transferred article, damage to the article can be prevented, transfer accuracy is improved,
Moreover, there are advantages such as low noise and improved workability.
