Description

Push-back rack for pallet loading {PUSH-BACK TYPE RACK FOR PALLETS}

The present invention relates to a pallet-loading PUSH-BACK rack, which allows five pallets to slide six pallets in one mouth and out of the cell, without interfering between the trolleys. It is a safe structure that does not fall down due to eccentric load even if it slides in the state that considerable load is applied to the lower leg and roller. It relates to a pallet-loading PUSH-BACK rack that minimizes space and increases space utilization.

In order to store pallets in which goods are stacked more efficiently in a logistics process in which a large amount of goods are moved and stored, a pallet loading rack having a storage space for each floor is used. It is divided into fixed and electric, but the present invention relates to a fixed pallet loading rack (hereinafter, rack).

In order to load the stacked pallets into the rack, lift the pallet with a forklift and push it into the storage space of the rack. In addition, we proceeded to release the goods.

On the other hand, when entering and leaving the pallet from the rack side, the forklift lifting the pallet must move every time along the side of the rack, that is, the length of the worker's work is increased and time-consuming work, such as poor workability,

The forklift must have a space to work while the forklift moves on the side of the rack, so if there are a lot of goods to be stored, the forklift moving space occupies a large part of the logistics storage space. There was a problem that can not be utilized efficiently.

The present invention has been devised in view of the above-described circumstances, so that the pallet loaded in the storage space can be moved back and forth inside the storage space by installing a transfer means under the storage space provided in each floor of the fixed rack body. Pallet loading and unloading operations can be carried out in front of the rack body to make loading and unloading operations easier, as well as PUSH-BACK racks for pallet loading to minimize the rack installation space for more efficient use of logistics storage space.

As it is coupled, the front feed roller 32 is coupled to the rail 20, the outer groove 22, and the rear feed roller 32 is coupled to the rail 20, the inner groove 21.

Through the present invention made as described above, the process of entering and leaving the pallet 40 stacked goods 50 is as follows.

As shown in FIG. 1, the present invention is made with the pallet 40 loaded in front of the rack A body 10.

Since a plurality of trolleys 30 are sequentially formed in the front lower portion of the storage space 10a provided in each floor of the body 10, the first pallet 40 is formed by the forklift 60. When lifted, the pallet 40 can be loaded on the upper surface of the uppermost trolley 30 supporting plate 30a.

Here, before the pallet 40 is loaded, the trolleys 30 are sequentially layered in the front lower portion of the storage space 10a, as shown in FIG. 5, at the height of the support leg 31 of each trolley 30. This is because a differential is provided, and due to the difference in height between the upper trolley 30 and the upper trolley 30, a portion of the upper trolley 30 is accommodated below the upper trolley 30.

Meanwhile, in order to load another pallet 40 onto the trolley after the first pallet 40 is loaded on the uppermost trolley 30 supporting plate 30a, the fork in the state in which the pallet 40 is lifted by the forklift 60 is lifted. The lift 60 is moved forward to push the uppermost trolley 30 on which the pallet 40 is already loaded to the rear of the storage space, and the upper 30 trolley 30 supporting plate 30a which is exposed after the uppermost trolley 30 is pushed out. By laying down the pallet 40 held by the forklift 60, the pallet 40 can be loaded.

By repeating this method, as shown in FIG. 7 in front of the rack A without moving the forklift 60, it is possible to load a plurality of pallets 40 inside the storage space 10a. When loading the last pallet 40 after loading the pallet 40 in the 30), the forklift 60 is pushed to the rear of the storage space (10a) foremost trolley (30) in the lifted state, The pallet 40 is finished by placing the pallet 40 on the upper surface of the rail 20 exposed in the space secured while the front trolley 30 is pushed.

When loading the pallet 40 in the rack (A) storage space (10a) through the above process, the trolley (30) is slid back and forth in the storage space (10a) by the rail 20,

The feed rollers 32 and the guide rollers 33 installed under the support legs 31 of the trolley 30 are rotated in the outer grooves 21 and 22 in the rail 20 to allow sliding of the trolleys 30. Will be

It is an auxiliary means to make it possible.

Meanwhile, when the pallet 40 is lowered from the storage space 10a of the rack A for shipment, the pallet 40 at the foremost front of the storage space 10a with the forklift 60 in front of the rack A body 10. To lift and lower the rack (A),

When the pallet 40 located at the front of the storage space 10a is lowered, the rear trolley 30 adjacent to the storage space 10a moves to the foremost front of the storage space 10a where the front pallet 40 is located, and the front trolley 30 is Due to the space generated when moving forward, the remaining trolleys 30 are also linked to move forward.

In this process, the rail 20 itself installed at the lower portion of the storage space 10a may be inclined because the rail 20 itself installed at the lower portion of the storage space 10a may be moved forward without applying any force to the trolley 30. Because it is achieved.

At this time, the inclination of the rail 20 is preferably used to adjust according to the type or load of the product 50 to be loaded,

The inclination of the rail 20 is to be adjusted so that the trolley 30 carrying the pallet 40 can descend to the front of the storage space 10a at an appropriate speed.

The rail 20 in the present invention is mounted on the upper surface of the horizontal support 12 coupled with the vertical frame 11 constituting the rack (A) body 10, so that the rail is adjusted by adjusting the horizontal support 12 installation height. It is preferable to adjust and use the inclination of (20).

On the other hand, since the trolley 30 moved forward by the inclined rail 20 should stop to reach the front of the storage space 10a, in the present invention, as shown in FIGS. 3 and 4, the front of the storage space 10a is vertical. The auxiliary support 13 is coupled to the frame 11, and the support 30 is moved forward by installing an elastic spring 13a on the left and right sides of the auxiliary support 13.
