DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a freezer facility provided with an automatic transfer device used for loading and unloading of frozen goods in a distribution warehouse or the like, and more particularly, to a structure for interrupting the flow of air to a freezing room in the refrigerator. The present invention relates to a freezer facility subjected to the above.

[0002]

2. Description of the Related Art Conventionally, in this type of freezer equipment,
A rack group is three-dimensionally framed on the floor in the building and installed in a plurality of rows, and the automatic transport device is moved up and down and traversed between these rack groups, and each of the automatic transport devices is used for frozen products. By automatically transporting to the rack position of
Some have a configuration that enables automation of storage and retrieval of frozen products, rationalization of inventory management work, and EDP (computer information processing) of office procedures.

[0003]

However, in the above-mentioned conventional automatic transfer device in a freezer facility, a traveling rail is laid along a depth direction on a floor between rack groups, and a traveling saddle travels on the traveling rail. On the other hand, while the loading saddle is provided on a column that stands upward from the traveling saddle so as to be able to move up and down, the traveling saddle and the loading tray are placed at each of the target rack positions of the rack group provided with the code plate. At present, it is performed by controlling the drive so that the vehicle can run and move up and down automatically.

[0004] For this reason, in order to achieve stable running of the traveling saddle by reducing the swing of the load receiving stand, it is necessary not only to increase the weight of the structure of the traveling saddle itself but also to enlarge it.
Since the traveling saddle is equipped with a drive control mechanism for all traveling and lifting, the overall weight of the device is increased, which limits high-speed operation and shortens the cycle time when goods are loaded and unloaded. And the running rails and running wheels are severely worn, resulting in poor durability.

Moreover, since a large dead space corresponding to the height of the traveling saddle is formed below the rack group installed in a plurality of rows, it is necessary to lift the entire rack group in accordance with the height of the traveling saddle. There is no effective use of the installation space.

Further, since the traveling / elevation drive control of the traveling saddle and the loading tray is performed by communication with the external control panel by the optical transmission means, real-time control cannot be performed, and the control mechanism on the traveling saddle and the external control Since it is necessary to separately adjust the operation with the mechanism, it is troublesome to debug the automatic operation software on site.

SUMMARY OF THE INVENTION An object of the present invention is to provide a freezer facility equipped with an automatic transfer device which enables high-speed operation by reducing the size and weight and maintains the inside of the refrigerator at an extremely low temperature. .

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to an ascending and descending drive control means using a wire rope in a warehouse of a building in which a plurality of rows of rack groups for accommodating goods are installed.

And an air flow blocking means is provided in the through hole.

In this case, the air flow cutoff means is provided with an outlet at the upper side of the frame forming the through-hole of the partition wall, and is provided with an inlet at the lower side thereof corresponding to the outlet. An air curtain mechanism is formed by sucking air blown by a blower from the blowout port at the suction port, and the air curtain mechanism is provided on at least one of a room temperature room side and a freezer room side in the refrigerator. In addition, a heater is provided around the air suction port of the blower, or a guide roller is provided in the through hole of the partition wall, and the wire rope is guided and held on the guide roller.

[0023]

As is apparent from the above description, the present invention relates to a lifting and lowering drive control means using wire ropes in a building in which a plurality of rows of racks for storing articles are installed. Since it has an automatic transport device including a frame and a carriage for automatically transporting a conveyed object by traversing the vertical frame, the vertical frame needs to be moved in the horizontal direction only by moving up and down in the height direction. As a result, the elevating frame, and hence the entire apparatus, can be reduced in size and weight, whereby high-speed operation can be performed and the cycle time at the time of loading and unloading can be reduced. .

In addition, since the cart is traversed on the lifting frame, the height of the cart from the floor can be reduced, and the dead space as in the prior art can be reduced. On the other hand, it is possible to install the lifting drive control means of the lifting frame and the traversing drive control means of the bogie on the outside, and the conventional optical transmission means becomes unnecessary. Control can be performed, and debugging of automatic operation software on site can be easily performed.

The interior of the refrigerator is divided into a freezing room in which a group of racks are installed and a room temperature room in which a vertical drive control means is installed adjacent to the freezing room via a partition. A through-hole through which the wire rope of the elevating drive control means for driving the inner automatic transfer device is inserted is provided, and an air flow shut-off means is provided in this through-hole, so that a temperature rise on the freezing compartment side due to air is prevented. And the freezer compartment can be maintained in an ultra-low temperature atmosphere.

Further, since the heater is provided around the blow-off port and the suction port of the blower in the air curtain mechanism constituting the air flow blocking means, icing of the air curtain mechanism can be reliably prevented.

Further, a guide roller is provided at a through-hole of the partition wall through which the wire rope is inserted, and the wire rope is guided and held on the guide roller. The wire rope does not come into contact with the air curtain mechanism of the air flow blocking means, thereby preventing damage to the air curtain mechanism.
