Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to, for example, a product set in a production line for accumulating or discharging a product flowing in the line without stopping the flow of the line. The present invention relates to an article storage device.

[0002]

BACKGROUND OF THE INVENTION Japanese Patent Publication No. 59-32362 discloses such an article storage device, which is generally shown in FIGS.
It has a configuration as shown in. That is, the apparatus is mounted on a frame 10, a plurality of fixed sprockets 12 rotatably mounted at predetermined positions on the left and right frame portions of the frame (in the example shown, mounted on a movable plate 14 which is vertically movable). ) Multiple movable sprockets 1
6, a pair of endless chains 18 that are respectively hung on the left and right fixed and movable sprockets and driven in a substantially vertical plane, and a plurality of endless chains that are set substantially horizontally with a predetermined interval therebetween. The article conveying member 20, the driving means (the first motor 22 and the second motor 24 in the illustrated example) for rotationally driving the sprocket, and the article A on the article conveying member 20 moved in the frame.
Has an article receiving section 26 for receiving the article from the outside, and an article ejecting section 28 for ejecting the article from the article conveying member moved in the frame to the outside.

In this apparatus, if the first motor 22 is driven with the second motor 24 stopped and the sprocket 12 connected to the motor is rotated clockwise (as viewed in FIG. 1), The length of the lower chain portion 18 'between the two sprockets connected to the first and second motors is reduced, whereas the length of the upper chain portion 18''between the sprockets is increased. Therefore, a large number of articles are stored and accumulated in this upper portion.

On the contrary, if the second motor 24 is driven while the first motor 22 is stopped, the upper portion 18 '' of the chain is moved toward the lower portion 18 'and accumulated. The article A is sent to the article discharge unit 28.

In order to feed an article onto the article carrying member of such an apparatus, a belt conveyer is provided so as to be adjacent to the article receiving section 26 and extend substantially parallel to the article carrying member 20. When a predetermined number of articles are supplied onto a portion of the belt conveyor corresponding to the article receiving section, the articles are conveyed by using a pusher.
Although there is a method of pushing the article storage device up to 0, if the article transport speed of the article transport line in which the article storage device is set is high, it is necessary to move the article in and out of the article storage device accordingly.

[0006]

SUMMARY OF THE INVENTION In view of the above points, an object of the present invention is to make it possible to properly carry in an article in accordance with the conveying speed even when it is set in an article conveying line where the article conveying speed is high. It is an object of the present invention to provide an article storage device according to the above.

[0007]

That is, the device according to the present invention comprises a frame, a plurality of fixed sprockets rotatably mounted at predetermined positions on the frame, and a movable sprocket movably mounted on the frame, and the fixed and movable sprockets. An endless chain that is hung and driven in a substantially vertical plane, a plurality of article conveying members that are set substantially horizontally to each other at a predetermined distance from each other, drive means that rotationally drives the sprocket, An article receiving unit for externally receiving an article on the article conveying member moved in the frame, and an article ejecting unit for ejecting the article from the article conveying member moved in the frame to the outside. An apparatus for supplying an article to an article accumulating device such as that adjacent to the article receiving section and substantially parallel to the article conveying member. First and second belt conveyors arranged in a vertical relationship with each other so as to extend, and an article that is set on the upstream side of the belt conveyor in the article conveyance direction and is supplied to the first belt conveyor Corresponding to the first and second belt conveyors, which is movable between the first position for moving and the second position for supplying the supplied articles to the second belt conveyor. And the first and second pushers for supplying the articles supplied on the first and second belt conveyors to the article conveying member through the article receiving section, and the article conveying members are adjacent to each other. It is characterized in that every two matching belts are driven so as to come to positions corresponding to the first and second belt conveyors.

[0008]

The apparatus according to the present invention has the above-mentioned structure, and the third belt conveyor transfers the articles from the upstream belt conveyor which conveys the articles to the apparatus. Since it receives and distributes it to the first and second belt conveyors and supplies it to the article conveying member, the article can be properly supplied even if the upstream belt conveyor has a high driving speed.

Third belt conveyor 3 movable between a first position for supplying the belt conveyor 30 and a second position for supplying the supplied articles to the second belt conveyor 32.
4 and. In the illustrated embodiment, the third belt conveyor is adapted to be pivotable between the first and second positions about the axis of the belt wheel at its left end, the left end of which is the upstream belt conveyor. It is set adjacent to the right end of 36, and receives articles from the belt conveyor 36 and distributes them to the first and second belt conveyors. Further, in the device according to the present invention, the first
First and second pushers (not shown) are provided corresponding to the first and second belt conveyors, and the articles supplied onto the first and second belt conveyors are simultaneously conveyed through the article receiving section 26. The material conveying member 20 is driven so that every two adjacent ones are intermittently moved to positions corresponding to the first and second belt conveyors. Has become.

As can be seen from the above structure, in the present invention, the article A conveyed from the upstream belt conveyor 36.
