In addition, a sliding frame is disposed below the chain, which is slidable parallel to the chain, has a fork holder horizontally on the article loading side, and has a locking pawl. The present invention relates to an article carrying-out device in which the chain can be rotated by engagement between a claw of a sliding frame and the chain when pushing inward, and the article is brought in,
The purpose is to provide a device suitable for efficiently carrying out articles stored in the upper part of a rack or the like or deep inside by using the fork part and its pushing force of a forklift that is commonly used for carrying out work. Specific embodiments of the invention will be described with reference to the drawings.

Both ends of a pair of groove shaped steels 3, 3, which hold two groups of rollers arranged side by side extending from the entrance side of the storage rack etc. toward the rear opening of the rack, are supported on the frame 4 of the rack. Located between the support rails 1 and 1 of at least a pair of articles, and located below the surface of the rails 1, and supporting rail 1
A channel-shaped guide rail 5, which extends parallel to the support rail 1 to its deepest part and is slightly shorter than the support rail 1 on the article loading side of the support rail 1, with the opening groove facing upward, is laid;
A roller 6 is provided on the lower surface within the groove of the guide rail 5. A slider 8 is fitted with a slider 8 having a push plate 7 attached to its end that protrudes beyond the surface of the support rail 1 with the lower edge of the push plate 7 supported on the guide rail 5. .

Located on the goods loading side of the guide rail 5, and a guide rail! A take-up drum 9 is located diagonally below the rack frame 4.
A strong band 10 made of, for example, nylon is connected between the drum 9 and the slider 8, and a long mounting shaft 11 of the winding drum has two pieces centered around the winding drum. Gears 1-, 2, and 12 are fixedly attached to the support rails 1, 1, and 12, which are located below the middle of the groups of rails 1, 1, and 5, using the groove steels 3, 3 that constitute the support rails 1. Gears 14, 14 on the other side corresponding to the gears 12, 12 are disposed using a horizontal rod 13 installed between them as a foothold, and a total of two chains 15 are installed between these two corresponding sets of gears 12, 14. ,1
A guide plate 25 for preventing the chains from sagging is attached between the forward and return side chains, and an attack member 16 is fixed to each link constituting both chains.

17 is a sliding frame installed below the pair of chains 15, 15, and a gutter-shaped fork holder 1 is installed on the article loading side of the rack.
8, and a pair of support arms 1 are placed inward from both ends at right angles J.
9, 19 are extended, and a plurality of roller groups including a pair of upper and lower rollers 20, 20 attached to the side surfaces of each support arm 19 are used to horizontally extend the groove-shaped steel 3 constituting the support rail 1. The sliding frame 17 is mounted by holding the bent portion 3a from both the upper and lower sides. The chains 15 are disposed so as to be movable in parallel to the chains 15, 15, and above the back of the gutter-shaped fork receiver 18, the chains 1
A pair of swingable engaging claws 21, 21 that engage with the fixed attack 16 are protruded from each link of 5, and these claws 21, 21' engage with the attachment 16 of the chain. In the past, the back of the claw 21 was brought into contact with a part of the sliding frame member to maintain the upright state and prevent it from swinging. , the spring 22 allows the claw to swing in an inverted position.
It is installed with the help of

The sliding frame 17, which is slidably attached using the support rail shape steel 3 as a guide, is a tension spring stretched between the outwardly bent end pieces 19a of the pair of support arms and the frame 4 of the rack. 23, 23, it is always set in a state where it is drawn toward the article loading port side. In the above configuration, first, a block of articles (hereinafter referred to as one article) placed on a pallet is moved with a forklift to a position above the support rails 1, 1 from the starting end side A of the support rails that serves as the loading entrance. The truck is loaded onto the pallet, and while being backed by a forklift at the rear of the pallet, it runs on two groups of rollers that make up the rails.
Gradually moving to the back, the next item placed on the pallet is placed on the support rail, and the storage operation continues with the next item pushing the previous item from behind.

During the storage operation of the article, as the article is moved to a deep place, the push plate 7 attached to the slider 8 comes into contact with the pallet on which the first article is placed, and the slider 8 moves the strip wound around the winding drum. While unwinding the body 10, the body 10 is guided by the guide rail 5 and moved to the terminal end of the guide rail (an entrance for carrying in the fabric articles). When the predetermined group of articles has been placed and stored on the support rails 1, 1, the push plate 7 of the slider 8 hits the pallet on which the first article is placed at the end (deepest part) of the guide rail 5. The belt body 10 is held in contact with the belt 10 in a stretched state.

As described above, the goods are carried in with support from subsequent goods.

On the other hand, when transporting articles, the fork portion of the forklift is used to push the fork receiver 18 of the sliding frame 17 and push the sliding frame inward into the rail.

During this pushing operation, the pair of engaging claws 21, 21 protruding from the sliding frame 17 are connected to the attachment 1 of each chain 15.
a gear 11 that engages with any one of the gears 6, rotates the chain in one direction, and is fixed to the mounting shaft 11 in response to the rotation of the chain in one direction;
The winding drum 9 is further rotated, and the band 10 is wound onto the winding drum 9 through this series of operations. The articles located on the carry-out side of the rail are sequentially moved to the starting end side of the rail by the push of the articles, and the articles are carried out by a forklift. The number of teeth of the gear 12 and the diameter of the winding drum 9 are adjusted so that the amount of winding of the band 10 corresponding to the depth of one pallet occurs by one pushing operation of the sliding frame by the folding forklift. is selected, one pushing operation of the sliding frame moves one pallet, and as the forklift moves backward, the sliding frame 17 is pushed against the back of the engaging claw 21 by the tension of the springs 23, 23. (rejects the group of attachments 16), the engaging pawl 21 returns to its original position while repeatedly swinging under the action of the spring 22, and waits for the next article carrying out operation.

Next, to explain the second embodiment (the one shown in FIG. 2), the difference from the above-mentioned first embodiment is the sliding frame 17.
Tension springs 23, 23 to constantly pull the
1 of the sliding frame 17 due to the deflection.
Naturally, the outwardly bent pieces 19a formed at the ends of the pair of support arms 19 of the pair of support arms 17 become unnecessary.

The number of teeth of the gears 12 and 14 and the diameter of the winding drum 9 of the band 10 are changed, and the engaging claws 21, 21 protruding from the upper part of the sliding frame 17 intentionally prevent the inverted movement upon return. There is no need to repeat the process, and therefore the provision of the spring 22 becomes unnecessary. In the second embodiment, the moving width in which the sliding frame 17 can be pushed to the maximum is divided into the number of possible articles to be carried in minus the amount of sorting, and one article is pushed in by one division of the moving width of the sliding frame. To explain this in more detail with numerical values, for example, the support rail 1 allows pallets carrying three articles to be placed side by side on the support rail 1. Assuming this, it is sufficient to wind up a length of the strip 10 corresponding to the depth of the pallet onto the winding drum 9 in stroke 112, which is the stroke at which the fork part of the forklift pushes the sliding frame 17 deepest. In this case, by reducing the number of teeth of the gears 12 and 14 and further increasing the diameter of the winding drum, the sliding frame 17 is pushed in the first time, and the second place is
That is, among the three articles carried in, the middle one moves to the outlet, and when the sliding frame 17 is pushed in the second time, the first one, that is, the article carried in first, moves to the outlet. . Then, by pushing the sliding frame 17 a second time, the sliding frame 17
However, when the next article is brought in, the slider is pushed by the article and moves to the end of the rail, and at this time, the strip 10 is unrolled from the winding drum. In response to this, the winding drum 9 rotates, and this rotation is sequentially manifested in the reverse rotation of its mounting shaft 11, gear 12, and chain 15, and the sliding frame 17 engaged with the attachment 16 of the chain 15. The sliding frame 17 returns to the loading port side via the upper claws 21, 21. Note that the state illustrated in Fig. 2 is the first state.
It is a top view at the time when the pushing operation of the sliding frame is completed for the second time. With this invention, it is possible to store the i
By winding the strip around the take-up drum, the articles are sequentially moved to the exit side while being pushed back, and the articles can be taken out easily and safely at low cost using an extremely simple device. In particular, when transporting goods located in the upper part of a high-rise building where the scaffolding tends to be unstable, a forklift can be repurposed, and the sliding frame can be pushed in with the fork part. Since the rotation of the chain and the winding of the belt onto the winding drum are easily carried out, it is extremely easy to carry out articles from the upper part of the rack. The attached slider does not require any special positional movement or other setting work, and is automatically guided to the desired position and installed when the item is being carried in, which also simplifies the mechanism. helpful,
By making the guide rail channel-shaped, fitting the slider into the groove of the rail, and placing the lower edge of the push plate in sliding contact with the guide rail, it is possible to reliably prevent the slider from swaying from side to side when running. To enable smooth loading and unloading of goods, and to reliably prevent the fork from sliding away from the fork holder by making the fork holder of the sliding frame in contact with the fork part of the forklift into a gutter shape. In addition, the sliding frame slides on the horizontal part of the slack section steel that constitutes the support rail, and slides using this part as a guide, making installation easy and ensuring parallel movement of the sliding frame. It is effective for smooth execution of work. The present invention is effective in simplifying the mechanism and saving energy, thereby making it possible to provide a device that is inexpensive and can minimize the occurrence of failures, meeting the demands of the energy-saving era.
