[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stacking device for stacking rectangular articles such as books in a predetermined attitude in a stacker.

[0002]

2. Description of the Related Art FIG. 4 shows a part of a conventional stacking device. The book 214 conveyed by the release type conveyor 212 is released to the chute 220. The book 214 slides on the chute 220 and falls into the groove of the feeder 216. Feeder 216 transports book 214 onto a stacker (not shown).

[0003]

In order to stack the books 214 in a predetermined direction in the stacker, the books 214 must be in a fixed position in the groove of the feeder 216. The chute 220 is required to have such a function. Conventionally, the book 214 is slid vigorously and collides with the groove wall 218 of the feeder 216 so that the book 214 is in a horizontal state.

However, as described above, the height H and the length L of the chute 220 are increased in order to make the book 214 glide vigorously and to keep the posture of the book 214 horizontal. There was a problem of getting worse. When the thickness of the book 214 exceeds 40 mm, the book 214 discharged from the chute 220 to the feeder 216
Had a problem of disturbing his posture.

[0005] An object of the present invention is to provide a stacking device capable of adjusting the posture of a book in a small space and loading the book.

[0006]

SUMMARY OF THE INVENTION The present invention is, first, a stacking device for a rectangular article provided below a drop-down type conveyor, wherein the sliding plate is inclined in the transfer direction of the drop-down type conveyor, and A chute provided with a stopper at the lower end of the plate, a pusher operating in the direction perpendicular to the sliding direction in the vicinity of the stopper, a butting plate provided in the operating direction of the pusher, and a chute side of the butting plate. The object has been solved by an apparatus including a stacker provided with an openable and closable receiving plate.

A second aspect of the present invention is a stacking device for a rectangular article provided below a release type conveyor, comprising a sliding plate inclined in the transfer direction of the release type conveyor and a stopper at a lower end of the sliding plate. A chute that can be inclined in a direction perpendicular to the transfer direction of the drop-down type conveyor, an abutment plate provided in the inclination direction of the stopper, and an openable / closable receiving plate provided on the chute side of the abutment plate. The object has been solved by a device comprising a stacker provided with a roller and a roller disposed on the surfaces of the slide plate and the stopper.

[0008]

The rectangular article is released from the release type conveyor.
The rectangular article slides on the slide plate of the chute and collides with the stopper to stop. When the pusher is activated, the rectangular article is ejected in a direction perpendicular to the sliding direction. The length of the chute is preferably set relatively short so that the posture of the rectangular article does not change.

The rectangular article vigorously discharged by the pusher collides with the butting plate and falls on the receiving plate. When the receiving plate is opened, the rectangular articles fall and are loaded in the stacker.

The operation of the stacking device according to the second invention is as follows. The rectangular article released from the release type conveyor slides on the slide plate of the chute, collides with the stopper and stops. The chute is inclined at right angles to the transfer direction of the drop-down conveyor. Further, since the slide plate and the stopper have rollers on their surfaces, they slide down on the chute by the action of gravity.

The rectangular article jumps out of the stopper, collides with the butting plate, and then falls on the receiving plate. When the receiving plate is opened, the rectangular articles fall and are loaded in the stacker.

FIG. 1 is a perspective view showing a first embodiment of a stacking device 10 according to the present invention. Reference numeral 12 denotes a release type bottom opening basket conveyor. A number of stacking devices 10 are provided in tandem in the transport direction of the bottom-open basket conveyor 12. Bottom opening basket conveyor 12
Releases the rectangular article 14 when it arrives above the predetermined stacking device 10. Hereinafter, a book is an example of a rectangular article.

The stacking device 10 includes a chute 20 and a stacker 30. The chute 20 is the sliding plate 22
And a stopper 24. The chute 20 is located below the bottom open basket conveyor 12. Sliding board 22
Are inclined in the conveying direction of the bottom-open basket conveyor 12. An angle-shaped stopper 2 is provided at the lower end of the sliding plate 22.
4, and a book 1 that has slid on the sliding board 22.
4 is stopped. The sliding plate 22 is provided with a sensor for detecting the passage of the book 14, that is, a photoelectric switch 26. A pusher 28 protrudes on the sliding plate 22,
After the photoelectric switch 26 detects the passage of the book 14, it operates in a direction perpendicular to the sliding direction of the book 14. The pusher 28 is driven by a motor, an air cylinder, or the like.

The stacker 30 is located on the side of the chute 20,
That is, it is located in the operating direction of the pusher 28. The stacker 30 has an abutment plate 32 and a receiving plate 34. The butting plate 32 receives the book 14 released by the pusher 28 and drops the book 14 on the receiving plate 34. The receiving plate 34 includes a pair of plates 36. When the plates 36, 36 are opened, the book 14 falls into the stacker 30.

FIGS. 2 and 3 show a second embodiment of the stacking device 110 according to the present invention. The stacker 130 of the stacking device 110 of the present embodiment is substantially the same as that of the first embodiment. Below, shoot 12
0 will be described.

The chute 120 of this embodiment is supported by a shaft 121 extending in the transport direction of the bottom-open basket conveyor 112, and can swing in a direction perpendicular to the transport direction.
The chute 120 includes a slide plate 120 and a stopper 130 as in the first embodiment. The sliding plate 120 is inclined in the transport direction of the bottom-open basket conveyor 112. The sliding plate 120 has a plurality of rollers 123 supported on a shaft extending in the sliding direction of the book 14. The stopper 124 has a plurality of rollers 125 supported on a shaft extending at right angles to the slide plate 122.

The chute 120 is inclined about an axis 121. The angle of inclination is preferably 15 ° to 25 °. Books 14 released from the bottom opening basket conveyor 112
Slides on the sliding plate 122 until it hits the stopper 124. Since the chute 120 is inclined in a direction perpendicular to the transport direction, the book 14 is moved by the action of
It begins to roll over 3,125 and slides down toward stacker 130. The book 14 collides with a butting plate (not shown) as in the first embodiment, and falls on a receiving plate (not shown).

[0018]

According to the first and second aspects of the present invention, the height and length of the chute can be reduced, and the space efficiency of the stacking device can be improved. Also,
Since the chute can be shortened, the rectangular article is not damaged. And the stacking device of the present invention does not deteriorate in function due to the thickness of the rectangular article, for example, even when applied to a book sorting / storage device, a unique problem due to the size of the book, That is, there is no problem that the attitude of a thick book is disturbed.
