Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a rotating shelving facility installed in a factory, for example, and used to store and store various parts.

BACKGROUND ART Conventionally, as this type of rotary shelving equipment, there is one that can be seen, for example, in Japanese Utility Model Application No. 61-52604.
That is, a pair of sprockets rotated by a motor are arranged in parallel at the upper and lower parts of the box-shaped housing. A chain belt is suspended between these sprockets, and a pair of support arms are attached to this chain belt at regular intervals.
A carrier is rotatably supported at the free ends of these support arms via support shafts. Further, one position holding arm is fixed to each support shaft in a non-rotatable manner, and a guide roller is rotatably supported at the other end of this position holding arm. On the left and right inner surfaces of the housing, an oval annular track having upper and lower arcuate portions is formed. This annular track has a concave groove shape, and the guide roller is fitted into the annular track to keep each carrier in a horizontal state at all times. When one of the sprockets is rotated by a motor, the chain belt suspended on the sprocket is rotated, and each carrier rotates while maintaining a horizontal state. After moving the desired carrier to the article insertion/ejection port, articles are taken in and out of the carrier through the article insertion/ejection port.

Problems to be Solved by the Invention According to the conventional type described above, since the carrier is connected to the support arm via the support shaft, it is very difficult to attach and detach the carrier. Therefore, even if you are replacing all the items in the carrier all at once or if the carrier is damaged due to operator carelessness, you can replace the items with the carrier attached or repair the damaged part. Such work and repairs were extremely inefficient and took a long time. For this purpose, it is conceivable to adopt the structure found in, for example, Japanese Unexamined Patent Publication No. 47-28650. That is, a pair of protruding pins that face each other and protrude laterally are attached at regular intervals between the left and right pairs of chains. The parts bucket is swingably supported via the protruding pin. That is, the protrusions attached to both the left and right sides of the parts bucket are provided with grooves that are open at the lower end, and the parts bucket is supported by fitting a protruding pin into the slot. Therefore, the carrier shown in the above-mentioned Japanese Utility Model Application Publication No. 61-52604 is provided with a protruding slot which is attached to the parts bucket shown in the above-mentioned Japanese Patent Application Publication No. 47-28650. It is possible to have a removable structure, but in this case, the carrier during patrolling
Due to vibrations during driving, vibrations from nearby equipment, or being hit by foreign objects that have entered the path of travel,
There was a risk that the carrier would swing around the ejector pin and the stored items would spill out.

An object of the present invention is to provide a rotary shelf facility in which the bucket can be easily attached and removed, and the bucket can always be maintained in a constant posture and not swing unexpectedly.

Means for Solving the Problems In order to solve the above-mentioned problems, the rotary shelving equipment of the present invention is provided with a pair of left and right endless rotating bodies stretched in the vertical direction, and bucket support arms are extended from multiple locations of these endless rotating bodies. An engaging bracket is connected to the outside, and rotatably attaches left and right pins to the free ends of these bucket support arms, and has an open upper part on the inner end side of these pins and a flat receiving surface on the inner lower part. At the same time, guide links are fixed to the outer ends of the pins, and endless guide rails for guiding rollers attached to the free ends of these guide links are fitted onto the endless rotating body and displaced back and forth. A bucket that can be disposed between both endless rotary bodies has a recess that can be freely engaged with the pin from above and a flat abutment surface that can freely come into contact with the receiving surface, on both sides of a bucket that can be disposed between both endless rotating bodies, and The engaging bracket is provided with an engaged bracket that can be freely engaged from above.

Effects According to the configuration of the present invention, when the engaged bracket is opposed from above to the pair of opposing engaging brackets, and the bucket is positioned between both endless rotary bodies, and the bucket is lowered, the engaged bracket is moved from above. the mating bracket is engaged with the engagement bracket, and
The recess is engaged with the pin, and the abutment surface is brought into contact with the receiving surface, whereby the bucket can be easily attached between the left and right bucket support arms. Also, contrary to the above,
By lifting the attached bucket upward, the engaged bracket can be separated from the engaging bracket,
The bucket can then be easily removed from between the support arms.

Moreover, the bucket is moved by the drive of the endless rotating body. At this time, the guide link moves together with the engagement bracket while being guided by the guide rail via the rollers while always maintaining a posture facing in a certain direction. Therefore, even if the driving direction of the endless rotating body changes, the engagement bracket rotates relative to the support arm via the pin, and its posture is maintained constant by the guide link, so that the engagement bracket does not oscillate. It can always move in a fixed posture. When the engaged bracket provided on the bucket belt engages with the above-mentioned engagement bracket, the flat contact surface contacts the flat receiving surface, so the bucket belt does not swing and always maintains a constant posture. Move while maintaining.

Embodiment An embodiment of the present invention will be described below based on the drawings.

Reference numeral 1 denotes a box-shaped enclosure, which is installed vertically on the floor 2. A pair of left and right driven chain wheels 3 is disposed at the upper part of the enclosure 1, and a pair of left and right drive chain wheels 4 is disposed at the lower part opposite to these driven chain wheels 3. A chain 5, which is an example of an endless rotating body, is stretched between the chain rings 3 and 4 that face each other in the vertical direction. The drive shaft 6 to which the drive chain ring 4 is attached is rotatably supported via a bearing 8 on a support frame 7 provided within the enclosure 1, and is rotatably supported by a drive shaft 6 provided within the enclosure 1 that can be freely driven in forward and reverse directions. It is interlocked and connected to device 9. This drive device 9 consists of a servo motor with an electromagnetic brake installed on a flange base 10, and its output shaft 1
1 and the drive shaft 6 are interlocked and connected by a wrap transmission device 12. A large number of buckets 13 are attached between the pair of left and right chains 5 via support arms 14. That is, the support arm 14 includes a pair of link plates 16, 17 attached via link pins 15 of the chain 5, and these link plates 16, 1.
This pin 18 is rotatably attached via a bush 19. An engagement bracket 20 with an open top is attached to the inner end of each pin 18, and this engagement bracket 20 has a pair of inner and outer L-shaped plates 21,
22, and pin 1 with their horizontal plate parts overlapped.
8, and a horizontal and flat receiving surface 23 is formed on the upper surface of the overlapping portion. Also, the top is open and the bucket is shaped like a long box 13.
has engaged brackets 24 attached to both sides thereof. This engaged bracket 24 is constructed by vertically attaching a channel-shaped member, and allows the inner L-shaped plate 22 to be freely inserted into the internal space 25, and the lower end can freely come into contact with the receiving surface 23. A horizontal and flat abutting surface 26 is formed, and a recess 27 with an open lower end that can be freely engaged with the pin 18 from above is formed in the center of the flange plate. A guide link 28 is fixed to each of the outer ends of the pins 18, and a roller 29 is rotatably supported at the free end of the guide link 28. This roller 29 is fitted into the guide rail 30, and thus the guide rail 3
It can be moved freely by being guided by 0. This guide rail 30 is an elliptical and endless shape having circular arc portions at the top and bottom, and is fitted onto the endless chain 5 and is disposed on the inner surface side of the support frame 7 so as to be displaced back and forth. . A loading/unloading port 31 is formed on one side of the moving route of the bucket 13, that is, at the lower front of the surrounding wall 1, and a receiving stand 32 is provided at the outer lower part of the loading/unloading port 31. 33 indicates an operation panel.

Next, the operation of the above embodiment will be explained. Both chains 5
To arrange the bucket belt 13 between the support arms 14 of the chain, first, as shown in solid lines in FIGS. Place bucket 13 between 5 and 5. Then, the bucket 13 is lowered, the engaged bracket 24 is engaged between the L-shaped plates 21 and 22 of the engaging bracket 20, and the pin 18
A recess 2 is located between both L-shaped plates 21 and 22.
7 and by bringing the contact surface 26 into contact with the receiving surface 23 as shown in the imaginary lines in FIGS. 1 and 2, the bucket 1 is moved between the left and right bucket support arms 14.
3 can be easily installed. In this way, a large number of buckets 13 are attached between both chains 5. Contrary to the above, by lifting the attached bucket cart 13 upward, the engaged bracket 24 can be separated from the engaging bracket 20, and the bucket cart 13 can be easily removed from between the bucket support arms 14.

The operation can be carried out by activating the drive device 9, moving both chains 5 in forward and reverse directions, and moving the groups of buckets 13. At this time, the guide link 28 is guided by the guide rail 30 via the roller 29 and moves together with the engagement bracket 20 while always maintaining a posture facing in a certain direction. Therefore, even when the chain 5 moves on an inclined or curved section, the engagement bracket 20 rotates relative to the bucket support arm 14 via the pin 18, and
The guide link 28 maintains the horizontal posture of the receiving surface 23. Therefore, the engagement bracket 20 can always move without swinging, with the receiving surface 23 always being horizontal. When the engaged bracket 24 engages with such an engaging bracket 20, the entire flat abutting surface 26 comes into contact with the flat receiving surface 23, so the engaged bracket 24 is received via the abutting surface 26. It is stably supported on the surface 23. Therefore, the bucket 13 does not swing and moves while always maintaining a posture with the opening facing upward. By moving the group of buckets 13 mentioned above, empty buckets 13 or those with a small storage capacity are moved to the loading/unloading port 3.
By stopping the bucket 13 opposite to the bucket 13, parts can be loaded into the bucket 13. Parts can be stored in this state. When carrying out parts (order picking, etc.), a bucket 13 is used to store the desired parts.
What is necessary is to stop it facing the loading/unloading port 31.

Effects of the Invention According to the present invention having the above-mentioned structure, the recessed portion of the engaged bracket is structured so that it can freely engage with the pin of the engaging bracket from above, so that attachment and detachment of the bucket can be made very easily. Therefore, when performing work such as repairing a bucket that has been damaged due to operator carelessness or replacing all the items stored in the bucket, the bucket can be removed and moved to a sufficiently spacious area for work. The bucket can also be easily installed after work. Therefore, work efficiency is high and work time can be shortened.

Moreover, since the buckets engage by surface contact, they can withstand vibrations generated during the operation of rotary shelving equipment, vibrations generated from peripheral equipment, or even when foreign objects that enter the bucket get caught in the buckets. Baketto always moves while maintaining a constant posture without shaking. This prevents the items stored in the bucket from spilling out.
