Description

[Detailed description of the invention] This invention consists of an endless chain stretched between a pair of vertical support shafts via a sprocket wheel, and an appropriate number of storage objects such as boxes attached to the chain. The present invention relates to an article storage device in which a chain is forcibly driven.

An article storage device in which endless chains are arranged horizontally and stacked in multiple stages, each chain is attached with an appropriate number of boxes or other article storage bodies, and each chain is driven separately or simultaneously. ,
Various structures are already known. In this device, a chain and other parts are attached to a frame made up of rod-like materials with the vertical direction turned horizontally, but the semicircular part of the chain requires quite a large space in order to rotate the storage body, and Since the load is also large, the structure of the frame at the shaft portions at both ends of the chain becomes complicated.

The purpose of this invention is to simplify the structure of the chain support shaft in a frame, and it is used as a support shaft attachment part of a frame in a claim in which rod-like elements arranged vertically and horizontally are combined. It is characterized by having a cantilevered support arm that is fixed at only one end.

To explain the device of the present invention with reference to the embodiment shown in the drawings, reference numeral 1 denotes a frame, which has a rectangular outer frame 2 with
A plurality of frame bases 4 each having a plurality of horizontally spaced supporting bars 3 fixed thereto are arranged with their outer frames 2 parallel to each other and spaced apart from each other. The outer frame 2 is connected by a rod-shaped connecting member 5 arranged horizontally.
Reference numeral 6 denotes cantilevered support arms that are protruded from opposite sides of the frame base 4 located inside the frame 1 in appropriate numbers from both ends of the frame 1. Only one end of the frame 1 on the center side is fixed to the receiving material 7 and is arranged slightly below each support beam 3. 8 is a shaft that is oriented vertically, has its upper part protruding above the support arms 6, and its lower end is pivoted to each support arm 6; However, it is fixed slightly higher than the support crosspiece 3.

Reference numeral 11 denotes an endless chain, which is constructed by connecting somewhat long links 12 with a shaft, and has a roller 13 projecting from the links 12 at the lower end of the shaft.
is installed. The link 12 is placed on the sprocket wheel 10, the roller 13 is engaged with the engagement recess 9, and the chain 11 is stretched between the sprocket wheels 10. 14 is made to protrude to the outer peripheral side of the chain 11,
A suitable number of trays are fixed to the chain 11 with one end of the bottom thereof placed on the chain 11, and a standing wall 15 is provided on each side of the chain 11 side and both sides adjacent to that side, Locking protrusions 16 that protrude upward are formed at both ends of the side opposite to the chain 11. 17 and 18 are the bottom outer surface of the tray 14, and on the outer peripheral side of the chain 11, the chain 11
The wheels are attached to the side and the opposite end, respectively, and their axes are in the width direction of the chain 11.

Reference numeral 19 denotes a guide rail with a concave cross section that is placed and fixed on a plurality of support bars 3 of the same height, and this is made to have approximately the same length as the straight part of the chain 11, and is placed at a position overlapping the lower side of the straight part of the chain 11. A roller 13 is slidably inserted therein. 2
0 is an inner rail that is parallel to the guide rail 19 and is arranged on the outer peripheral side thereof, 21 is an endless outer rail that is arranged outside of the inner rail 20,
The rails 20 and 21 are also mounted and fixed on the support crosspiece 3. Then, wheels 17 are mounted on the rails 20 and 21,
18 are placed on each tray 14, and each tray 14 is maintained in a horizontal state by the advancement of the chain 11 and is able to rotate. The rails 19, 20, 21 may have approximately the same length as the interval between the adjacent frame bases 4, 4, and may be fixed to the support beams 3, 3, or may be fixed continuously. Reference numeral 22 denotes a box-shaped article storage body placed on each tray 14, which is fitted inside the vertical wall 15 and the locking protrusion 16. The locking protrusion 16 prevents the storage body 22 from jumping out from the tray 14 due to centrifugal force when the chain 11 turns, but it is set to a height that allows the storage body 22 to be pulled out horizontally. The cross section of the chain 11 in the width direction is a mountain-shaped slope.
The cross-sectional shape of the locking protrusion 16 can be semicircular, so long as it can lock the storage body 22 and draw it out.

23 is a driving sprocket wheel fixed to the lower side of the sprocket wheel 10 of one shaft 8 in the pair of shafts 8, 8;
This is driven by a motor 24 fixed to the frame 1 via a drive chain 25. 26 is a tension wheel of the drive chain 25.

This device stores and stores articles in each storage body 22 attached to a chain 11.
When taking out an article stored in the storage unit 22 or storing an article in the storage unit 22, the storage unit 22 is designated and its data is input to a control device (not shown).
Then, the motor 24 of the designated stage is driven according to the designated storage body 22, and the chain 11 of the motor 24 of the designated stage is driven.
Swirl. When the specified storage body 22 reaches a predetermined delivery position, the motor 24 stops, and articles can be taken in and taken out at that position.

The frame 1 that supports the chain 11 and others is made of horizontally and vertically arranged rod-shaped materials, and has a shaft 8.
Each of the support arms 6 to which the chain 11 is attached is fixed to a support member 7 whose center end is oriented vertically in the longitudinal direction of the chain 11. That is,
The support arm 6 is provided in a cantilevered manner, with its free end facing away from the center of the chain 11, and a vertical bar supporting the support arm 6 is provided around the rotating side of the storage body 22. No need to place it. Therefore, sprocket wheel 1
It is possible to easily obtain a turning space for the storage body 22 consisting of a box attached to the chain 11 that rotates along the chain 11, and it is possible to use a storage body 22 of any size, and it is possible to store various articles. You can get a storage device that can store.

The frame 1 can be constructed by suitably combining vertical and horizontal bars, but as in the embodiment shown in the drawings,
A horizontally oriented support bar 3 is fixed in the outer frame 2, and an appropriate number of frame base bodies 4 each having a support bar 3 corresponding to the number of stages of the chain 11 are arranged in parallel, and an adjacent outer frame 2 are connected to each other by the connecting material 5 to form the frame 1, it is possible to simplify the formation of the frame 1, and it is also possible to easily obtain the frame 1 of any length by simply increasing or decreasing the frame base 4. It is. The frame base 4 has a support crosspiece 3 fixed in advance, and rails 19, 20,
21 etc. can be placed and fixed on the rails 19, 2.
0, 21 etc., and the rails 19, 20, 21 are installed and fixed between each support beam 3.
etc. serve to connect each frame base 4, making it possible to obtain a stronger frame. If necessary, a vertical member may be fixed to the frame base 4 that is perpendicular to each support bar 3 and connects them to each other.
The strength of the frame 1 can be improved, and the assembly of the frame 1 or the attachment of the chain 11 and other parts thereto can be facilitated. In addition, by fixing the two support members 7, 7 to the outer surface of the frame base 4, the two support arms 6, 6 cantileverly protrude from the lower side of the support crosspiece 3, and the sprocket wheel 10 Not only can the shaft to which the sprocket wheel is attached be firmly supported, but also the mounting position of the sprocket wheel 10 can be set at the same height as the guide rail 19.
