Description

[Detailed Description of the Invention] This invention relates to an entrance/exit shielding loading/unloading device for loading/unloading cargo (stored items) into/out of a low-temperature warehouse such as a refrigerated warehouse or a frozen warehouse.

Conventionally, as shown in FIG. 1, an entrance/exit shielding loading/unloading device for a low-temperature warehouse is provided with a front chamber 7 surrounding the entrance/exit 2 of the low-temperature warehouse 1 on the outside of the low-temperature warehouse 1, and a front chamber 7 surrounding the entrance/exit 2 of the front chamber 2. 1 opening/closing door 9 is provided, and a second opening/closing door 1 is installed at the entrance/exit 2 of the low temperature warehouse 1.
0, an external cargo receiving conveyor 11 is provided at a position facing the entrance 8 of the front room 7, and a relay conveyor 12 is provided inside the front room 7. Furthermore, a cargo receiving conveyor 12 is provided inside the low temperature warehouse 1, and a cargo receiving conveyor 11 is provided in a position facing the entrance 8 of the front room 7. Trolley 5
A model equipped with this is known.

However, in the case of this type of entrance/exit shielding loading/unloading device, it is necessary to protrude the front chamber 7 on the outside of the low temperature warehouse 1, and as a result, the planar shape of the entire building is
Since it is not square, the site cannot be used effectively, and the first opening door 9 and the second opening door 1 cannot be used effectively.
0 and the receiving cart 5 are each moved by separate drive control devices, so there is a drawback that a large number of drive control devices are used.

The object of this invention is to provide an entrance/exit shielding loading/unloading device for a cold storage warehouse that eliminates the above-mentioned drawbacks.

Next, this invention will be explained in detail using illustrated examples.

Figures 2 to 5 show an embodiment of this invention, in which a sliding door is installed on the outside of the entrance 2 in a low-temperature warehouse 1 that accommodates a large number of multi-tiered stacked shelf rows 13 and shelf lifts 14. Door 3 is provided,
A tunnel-shaped enclosure frame 4 made up of left and right side wall plates 15 and a ceiling plate 16 is disposed in the low temperature warehouse 1 so as to face the entrance/exit 2, and the front end of the enclosure 4 is above the entrance/exit 2. It is fixed or joined to the edges and side edges in an airtight manner, and the lower end of each side/wall plate 15 in the enclosure frame 4 is connected to the floor 1.
7 in an airtight manner.

Wheels 18 of the loading truck 5 that runs between the rear position of the enclosure frame 4 and the inside of the shielding frame 4 in the low temperature warehouse 1
is a trolley running rail 19 fixed on the floor 17
The loading truck 5 is equipped with a large number of conveyor rollers 20 for transporting loads extending in the left-right direction, a traveling drive device, and a roller drive device, and furthermore, the rear of the loading truck 5 is provided with the enclosure frame. A shielding board 6 for closing the rear end opening of 4 is fixed. A lower sealing material 21 made of hollow rubber is attached and fixed with adhesive to the lower end of the shielding panel 6 to seal between the shielding panel 6 and the floor 17 and the trolley running rail 19. A rear sealing material 22 made of hollow rubber for sealing between this and the shielding board 6 is attached and fixed to the part with an adhesive.

A plurality of multi-tiered stacked shelf rows 13 are provided in the low temperature warehouse 1 and extend in the front and back direction with a lift passage 23 between them.Rails 24 for lift travel are provided at the upper and lower parts of the lift passage 23, and the lift travel The rail 24 is used to connect the enclosure frame 4 and the multi-tiered stacked shelf row 1.
The shelving lift 14 extends to the side of the loading platform running path between the end of the loading platform 3 and runs guided by the lift traveling rail 24. 26
It is equipped with Further, outside the entrance/exit 2, an external cargo receiving conveyor 11 consisting of a roller conveyor is installed.

When loading cargo (items to be stored) 27 from the outside onto the shelves in the multi-tiered stacked shelf rows 13 in the low-temperature warehouse 1, the cargo 27 is first placed on the external receiving conveyor 11 using a forklift or the like, and then the cargo is placed on the external receiving conveyor 11 as shown in FIG. As shown, the door 3 is opened and the cargo 27 is transferred from the external receiving conveyor 11 to the receiving truck 5, and then the door 3 is closed. Next, after the loading truck 5 is moved backward to the position shown in FIG. It is stored on a predetermined shelf in the stacked shelf row 13.

Baggage 2 stored on the shelves of the multi-tier stacked shelf row 13
7, first, the telescopic fork 26 of the shelf stacking lift 14 receives the cargo from the shelf, then the shelf stacking lift 14 is moved to a position opposite to the side of the receiving cart 5, and then the cargo is removed from the telescopic fork 26. is lowered onto the receiving truck 5, and then the receiving truck 5 is moved forward into the enclosure frame 4, and the rear end opening of the enclosure frame 4 is closed by the shielding board 6. Next, the door 3 is opened and the cargo is transferred from the receiving cart 5 to the external receiving conveyor 11, and then the door 3 is closed and the cargo is transferred to the external receiving conveyor 1.
The cargo above 1 is received by a forklift or the like and transported.

When implementing this idea, the rear sealing material 22 may be pasted and fixed around the front surface of the shielding panel 6, and the rear sealing material 22 may be attached and fixed around the front surface of the shielding panel 6, and separate rear sealing materials may be attached to the rear end of the enclosure frame 4 and around the front surface of the shielding panel 6. may be pasted and fixed. Furthermore, as the sealing materials 21 and 22, closed-cell foamed plastic or other arbitrary sealing materials may be used instead of hollow rubber.

According to this invention, a plurality of multi-tiered stacked shelf rows 13 are provided in the low temperature warehouse 1 and extend in the front and back direction with a lift passage 23 in between, and the lift passage 23 is provided with a rail for running a lift, and the lift passage 23 is provided with a rail for running the lift. The shelf lift 14, which travels guided by traveling rails, includes an elevating loading platform 25 and a telescopic fork 26 attached to the elevating loading platform 25, and an opening/closing door 3 for opening and closing the entrance/exit 2 of the low temperature warehouse 1 is provided. , the front end of a tunnel-shaped enclosure 4 disposed in the low-temperature warehouse 1 is airtightly connected to the peripheral edge of the entrance 2, and the enclosure 4 in the low-temperature warehouse 1 is
An enclosure frame 4 is provided between the rear end portion and the multi-tiered stacked shelf row 13 and at the rear of the loading truck 5 that runs within the enclosure frame 4.
A shielding board 6 that opens and closes the rear end opening is fixed, and the lift running rail extends to the side of the loading carriage running path between the enclosure frame 4 and the end of the multi-tiered stacked shelf row 13. Therefore, there is a cargo receiving cart 5 that transfers cargo to the shelf stacking lift 14 and the cargo receiving cart 5.
The rear end opening of the enclosure frame 4 can be opened and closed using a shielding board 6 attached to the rear of the enclosure frame 4.
Therefore, compared to the conventional case, the number of drive control devices used can be reduced, which is economical, and since there is no need to protrude a front chamber for shielding on the outside of the cold storage warehouse 1, the overall planar shape of the building It is possible to use the site effectively by making the square shape, and even if the shielding board 6 is fixed to the rear of the loading truck 5, it will not interfere with the delivery of cargo between the loading truck 5 and the shelf lift 14. Furthermore, when one of the opening/closing door 3 and the shielding panel 6 is opened, the other can be closed, so the amount of air escaping from inside the low temperature warehouse 1 can be reduced. Effects such as this can be obtained.
