Description

DETAILED DESCRIPTION OF THE INVENTION Q: Industrial application field
The present invention relates to a conveying device that efficiently conveys articles to a predetermined position by a conveyor (1) while aligning the orientation of the articles.

O Prior art This type of article conveying device is known as the Japanese Patent Publication No. 57-2937
``A device for conveying packaged eggs'' is disclosed in Japanese Patent Publication No. 0.

In the above-mentioned conveyance device, when transferring articles (packed rabbits) from the multiple rows of standby conveyors to the high-speed conveyor, the standby conveyor is used only when there is room for the articles to fit between the conveyed articles on the high-speed conveyor. The conveyed article is driven to be transferred from the standby conveyor to the high-speed conveyor so as not to come into contact with the conveyed article on the high-speed conveyor.

Problems to be Solved by the Invention In the above-mentioned conveying device, since the conveyed articles are sent to the conveyor that is operating at high speed, the mutual interval between the conveyed articles on the high-speed conveyor is extremely large compared to the area occupied by the conveyed articles. When the value of conveyance is poor, and the time to feed the high-speed conveyor is at the bare minimum, the bags collide with each other on the high-speed conveyor and are pushed together, causing the bags to turn sideways or diagonally. There are disadvantages such as irregularities such as the following.

Means for Solving Problems O The present invention provides a third conveyor (1) for transferring the conveyed articles on a plurality of standby conveyors (2) onto the conveyor conveyor (1).
3) are connected to each standby conveyor (2),
When the conveyed article is waiting in the waiting area (B) of the waiting conveyor (2), and when the limit switch is activated, the feeding is carried out at a predetermined relative position where the waiting area and the feeding area (A) are made to face each other. The conveyor (1) is stopped when there is no article to be conveyed in area (A), and when there is an article to be conveyed in the feeding area (A) opposite to the waiting area (B) under the above conditions, and all the conveyor A first control means (11) for controlling the conveyor (1) to operate when there is an article to be conveyed in (A); is present, the waiting conveyor (2) is stopped and the waiting area (
When there is no transported article in B) and in the waiting area (B)
), a second control means (12) for controlling the standby conveyor (2) to operate at least when the third conveyor (3) starts operating even if there is an article to be transported on the third conveyor (3);
When the conveyor (3) is stopped and the conveyed article is present in the waiting area (B) on the waiting conveyor (2) and the conveyor (1)
) to start the third conveyor (3) when there is no conveyed article in the upper feeding area (A) and stop the third conveyor (3) when the conveyed article to the feeding area (A) is completed. A control device (10) including a third control means (13) for controlling is provided, and by feeding the conveyed article from the standby conveyor (2) when the conveyor (1) is stopped, the article is placed on the conveyor (1). The mutual spacing between conveyed articles is kept to the minimum necessary.

○ Effect of the invention j The general conveyor (1) is rotationally driven by the rotation of the first motor (5), and its stop position is determined by the operation of the first sensor (limit switch) (14) to extend the standby conveyor (2). The stop timing is set so that the feeding area (A) is located on the line. When a conveyed article is detected on a predetermined waiting area (B) of the waiting conveyor (2), the waiting conveyor (2) stops. When the transport conveyor (1) and the standby conveyor (2) have stopped and there are no articles to be transported in the feeding area (^) including the transport conveyor (1) and the third conveyor (3), the standby conveyor (2) and the third conveyor The conveyor (3) is operated, and the transfer conveyor (1) is transferred from the standby conveyor (2).
