Abstract

PURPOSE:To realize efficient taking out of even a thin article by scooping up from a tray an article in the same posture as its stored posture by means of a click driven by a conveyor and sending the article out to a sliding board and further guiding it into a recovery container by means of said board. CONSTITUTION:A device, for taking out an article 7a from the interior of a slant tray 1 to the exterior of said tray 1, is provided with a conveyor 21 equipped with an endless belt 31 and slanting at a position facing the slanted lower end face of the tray 1, while the endless belt 31 is equipped with a click 26. Further, the upper end of a slant sliding board 24 is provided at a position where the article sent out from the upper end of the conveyor 21 is received, while an entrance of the recovery container 25 is provided at a position where the article sent out from the lower end of the sliding board 24 is received. Thus, even such a thin article as a book erected in the tray can be efficiently taken out without being damaged.

Description

[Detailed description of the invention] The present invention relates to a device for taking out stored articles.

Conventionally, as a device for taking out articles in a tray, a conveyor belt is passed through the tray from bottom to top to scoop the articles in the tray onto the conveyor belt, and then the conveyor belt is driven to scoop out the articles. However, in this case, the entire belt conveyor must be moved downwards, resulting in poor work efficiency when successively taking out articles from the tray. Furthermore,
The belt conveyor has a rounded end, making it difficult to remove thin items such as books.

One method for taking out thin items such as books is to use a vacuum suction device to adsorb the item and then take it out from the tray, but in this case, the suction work is added to the removal work, resulting in poor work efficiency. In the case of articles that are difficult to adsorb to, there is a disadvantage that it is not possible to take them out. There is also the so-called Daruma-otoshi method of taking out items, but in this case, the frictional force and external force applied to the items are large, so the items are easily damaged, and thin items such as books cannot be stored vertically in the tray. It was impossible to remove the item without damaging it.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus for efficiently taking out thin articles stored vertically in a tray without damaging the articles.

The gist of the present invention is that, as a basic configuration, an apparatus for taking out an article from an inclined tray to the outside of the mI tray has a fl.
A conveyor having an endless belt inclined at a position facing the slanted lower end face of the tray shown in J is arranged, claws are provided on the endless belt, and the upper end of an inclined sliding plate is arranged at a position to receive the articles sent out from the upper end of the conveyor. The picking device is characterized in that the entrance of the collection container is located at a position R to receive the articles sent out from the lower end of the sliding plate, and the picking device is arranged in the same position as the one in which the articles are stored from the tray with claws driven by a conveyor. While still in that position, scoop it up and send it out onto the sliding board.
The purpose is to guide the items into the collection container using a sliding plate.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 shows the layout of a book distribution center, and in the area sandwiched between the running rail 6a of the stacker crane 6 and the running rail 8 of the picker 9, the tray 1 is placed in an inclined position as shown in FIG. It has a shelf 4 that can be stored three-dimensionally. A branch path of the warehousing conveyor 2 extends to the 6th shelf 4,
At the branching part, there is a detector 3 for detecting tray l, and a detector a3 for detecting tray l.
and a pushing device 5 that pushes the tray 1 toward the branch road in response to the detection signal. A delivery conveyor 11 is provided to the other end of the shelf 4.
The collection conveyor 11 connected to a is extended, and
The branch path of the empty tray collection conveyor 13 is extended.

As shown in FIG. 2, the picker 9 is movable up and down between a traveling body in which running wheels 15 driven by a motor 16 are mounted on rails 8, a support frame 17 erected on the travel body, and the support frame 17. an elevating body 18 attached to the elevating body 18, a horizontally extendable fork mount W122 installed on the elevating body 18,
A picking device installed on the fork device 1j22,
It consists of a rope 19a connected to the elevating body 18 and operated by a winch 19, and a control device FR20 for the picker 9.

The picking device is as shown in FIG. That is, the belt support pair 21 is installed obliquely on the fork device (n) via the support platen (33), and the conveyor bell (31) is installed.
A protruding hook is fixed to the surface of the tray L with a length enough to accommodate the thickness of one book 7a in the tray l. Among the belt pulleys 30 and 31 of this belt conveyor 21, a gear 4 is attached to the shaft of the lower belt pulley (supply), a worm gear Z is meshed with this gear 6, and the rotation of a motor n is connected to this worm gear train. The shaft is attached and the motor thorn is installed on the fork device w22. Belt conveyor 2
The oblique sliding plate body, the upper end of which is located close to the upper end of 1, is installed on the fork device n via a support platen 34. A collection container 25 is disposed below the lower end of this sliding root girth and is installed on the fork mount 122. Collection container δ
is a container having an entrance open at the top, and inside thereof is provided with a receiving plate supported diagonally by coil springs 35a and 35b.

Guide plates 24a and 24b are fixed to the width ends of the sliding bases to adjust the sliding and descending posture of books that protrude above the sliding surface.

Next, the operation will be explained.

When the tray 1 containing the books 7a is sent in the direction of the arrow A on the receiving conveyor 2, the detector 3 or the tray 1
is detected, and in response to the detection signal, the pushing device 5 pushes out the tray 1 in the direction of arrow B to flow it to the shelf 4 side. This tray 1 is scooped up from the warehousing conveyor 2 by a stacker crane 6 and stored on a shelf 4. If there is an empty tray 12 on the shelf 4, the tray 12 is scooped up from the shelf 4 and delivered to a conveyor 13, and sent to a work place where books 7a are packed into trays L.

When taking out the required amount of books 7a from the stored tray 1, the conveyor 21 is made to face the location of the tray 1 where the books 7a to be taken out are stored. This face-to-face work involves rotating the running wheels 15 with the motor 16 to move the picker 9 along the rail 8, and operating the rope 19a with the winch 19 to raise and lower the elevating body 18 along the support frame 17. This is done by conveyor 21
If it is placed on the front of the target tray 1, it is a fork mounting!
22 to the shelf 4 side and move the conveyor belt 31 of the conveyor 21 closer to the inclined lower end surface of the tray 1. Next, when the motor η is driven to rotate the worm gear train, the rotational force is transmitted from the gear 4 to the belt pulley recess, and the conveyor bell 31 begins to be driven endlessly.

Therefore, the conveyor belt 31 and the integrated jar claw begin to move, and this claw passes through the tray l, and the books 7a1
Immediately lift the book diagonally in the F direction with your nail y and pull it out. The scooped book 7a rests on the surface 310 while being supported by the claws X, and does not fall.

The books 7a extracted from the tray 1 in this manner are sent from the upper end of the belt conveyor 21 to the sliding board side, and the books 7a slide down the sliding slope and enter the collection container. The book 7a that has entered the collection storage n25 is placed on the receiving plate A, and the book 7a
The springs 35a and 35b contract under their own weight, creating a space in the upper part of the collection container δ into which the next book can be placed.

When the book 7a descends with a sliding board, the guide board a,
At step 24b, the posture of the descending book 7a is kept constant, and the book is collected into the collection container 5 in a constant posture.

This collection operation is carried out one book at a time by the number of target take-outs by continuously driving the conveyor bell 31 endlessly. When the books 7a are taken out one by one from the tray 1, the books 7a remaining in the tray 1 slide down to the lower part of the tray 1 due to the inclination of the tray 1, that is, to the position where the nail thorns can reach, and are packed together. Therefore, continuous extraction is possible.

When the removal work for the number of target pickers is completed, the fork equipment RF122 is retracted toward the elevating body 18 so that the conveyor 21 can be moved away from the tray 1 side, and then the picker 9 is moved to move the elevating body 18. The collection container 5 is moved up and down to approach the collection conveyor 11 side.

Then, the books 7a in the collection container are transferred to the shipping tray 7, and transported from the collection conveyor 11 to the delivery conveyor 1.
1 Send it out via a. If it is difficult to transfer the collection container 6 to the shipping tray 7, use a fork mount.
22 side, transfer it to the collection conveyor 11, and set the empty collection container δ on the fork unit 51iZi.

As described above, according to the present invention, it is possible to tilt the tray and use the claws to take out the articles that approach the lower end of the inclination within the tray, and also to move the entire conveyor up and down to scoop up the articles. Moreover, since the stored state of the articles does not have to be stacked one on top of the other, even thin articles stored upright can be taken out efficiently and there is less damage to the articles.
