Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to an apparatus for cutting out an article placed on an inclined conveyor, and is particularly suitable for an article having a high center of gravity. The present invention relates to a device for cutting out usable articles.

(Prior Art) As a conventional technique relating to an article cutting device, those described in Japanese Patent Publication No. 47-28868 and Japanese Utility Model Publication No. Sho 63-41026 are known.

Explaining the prior art described in the above publication, Japanese Patent Publication No. 47-28868 discloses a free roller conveyor that inclines and sends a load from its supply side to its discharge side under its own weight.
A luggage unloading device having a movable stopper that is provided on the discharge side and is always held in a locked state is described.

Japanese Utility Model Laid-Open Publication No. 63-41026 discloses an article cutting device including a wheel conveyor row having a fixed stopper for locking an article, and an article delivery device which is vertically movable between the wheel conveyor rows. Have been described.

(Problems to be Solved by the Invention) However, the above-described conventional technology has the following problems.

That is, the load removing device described in Japanese Patent Publication No. 47-28868 is designed to take out the load (article) by lowering (substantially moving up and down) the locking piece of the movable stopper below the roller. Therefore, the height of the locking piece cannot be increased. In the article cutting device described in Japanese Utility Model Application Laid-Open No. 63-41026, the article delivery device is raised above the fixed stopper (substantially moved up and down) to cut the article. Therefore, the height of the fixed stopper cannot be increased. Therefore, if an article at a high center of gravity is accelerated and collides with a stopper at a low position, the article falls over the stopper as a fulcrum, and the article cannot be stopped.

Therefore, the object of the present invention is to provide a stopper to a high position, and to cut out an article that can be reliably stopped by the stopper even if an article at a high center of gravity collides with the stopper in an accelerated state. It is to provide a device.

(Means for Solving the Problems) The gist of the present invention that has solved the problems is as follows: 1) In a device for cutting out articles placed on an inclined conveyor, a swinging conveyor is swung at a lower end of the inclined conveyor. The conveyor is swingably provided so that the upstream end thereof can be higher than the conveying surface of the inclined conveyor, and is provided between a standing position substantially orthogonal to the conveying surface of the swinging conveyor and a prone position which sinks below the conveying surface of the swinging conveyor. The stopper is pivotally supported at a position below the swing conveyor so that the stopper can be raised and lowered, and a space is provided for the stopper in the swing conveyor, and the swing conveyor is located between the upright position of the stopper and the upstream end of the swing conveyor. A driving means for raising and lowering the stopper is provided for securing a distance on which one or a required number of articles can be placed on the conveyor surface of the conveyor. An article cutting device characterized in that a link for interlocking the upper end of the conveyor to swing so as to be higher than the conveying surface of the inclined conveyor is attached between the stopper and the swinging conveyor. The article cutting device according to claim 1, further comprising a plurality of free rollers.

(Operation) In the present invention, when the stopper is erected by using the driving means so as to be substantially perpendicular to the conveying surface of the swing conveyor,
The articles placed on the inclined conveyor move toward the lower end direction (downstream direction) of the inclined conveyor, transfer to the swinging conveyor provided at the lower end, and stop at a stopper that stands up substantially orthogonally. One or a required number of articles are placed between the stopper and the upstream end of the swinging conveyor.

Then, when the stopper is rotated to the prone position by the driving means, the articles stopped by the stopper start moving the swinging conveyor in the downstream direction and are discharged. At the same time, when the stopper sinks to the prone position, the swing conveyor swings by the link, and the upstream end of the swing conveyor becomes higher than the conveying surface of the inclined conveyor, and the transfer of articles from the inclined conveyor to the swing conveyor is prevented. Is done.

Therefore, only the articles stopped by the stopper on the swinging conveyor are discharged (cut out) from the lower end of the inclined conveyor.

Then, when the stopper is moved from the prone position to the upright position by the driving means, the upstream end of the swinging conveyor is lowered by the link, and the conveying surfaces of the inclined conveyor and the swinging conveyor become the same, and the articles on the inclined conveyor are moved to the swinging conveyor. One or a required number of articles are placed on the swinging conveyor as described above by hitting the stopper that has risen after moving on. These steps are repeated to cut out one or a required number of articles on the inclined conveyor.

The stopper of the present invention is pivotally supported to rotate to the high position of the swinging conveyor, so that even if the article at the high center of gravity collides with the stopper in an accelerated state, the article is reliably stopped by the stopper. Is done.
