Description

  The present invention relates to a distribution rack for picking goods at a merchandise distribution base, and more particularly, to a rack booth for maintaining a freezing or refrigeration environment for goods requiring refrigeration.

  In general, in goods storage and storage warehouses, when goods are shipped, a large number of products are efficiently received or stored, and then those products are selected and taken out by ship-to destination and placed in containers by ship-to party. Sort out and ship. In particular, at the product distribution center, products to be shipped are placed on individual product shelves, and an operator selects and picks those products based on the shipping information, and puts them into containers by shipping destinations that flow on the conveyor. The collected containers are shipped to the customer. The operations of selecting individual products, sorting them by shipping destination, and putting them into containers are collectively referred to as picking operations.

  The picking operation is a basic method in which an identification display such as a barcode attached to a product is read using a device such as a barcode reader, and is put into a shipping container, case or oricon according to the displayed shipping destination information. Since such an old method is a complicated operation, it has been reviewed by various technological developments. Currently, the operator picks the product from the product shelf according to instructions such as the lighting of the lamp linked to the shipping information of the warehouse management system of the entire product distribution center, and similarly puts the product on the shipping container on the conveyor that is illuminated by the lamp. A simplified shipping system that minimizes picking mistakes is used.

  However, since the work of picking various types of products for each shipping destination involves manual work by an operator, it is a simple continuous work, but it is a simple input work (hereinafter referred to as “picking mistake”). .) Is also likely to occur. In recent years, various techniques for preventing picking mistakes have been developed, and various technical ideas have been proposed.

  The present invention relates to a technique for efficient refrigeration processing when goods that require freezing or refrigeration are stored at a merchandise distribution base, and are arranged / pickled and shipped. In such work, recent refrigerated and frozen products have been changed so as to finely set the temperature range of the cold storage according to the product characteristics, and therefore, particularly pay attention to the catering picking work. When the product is in a freezing temperature zone such as ice cream, it must not be thawed, so equipment such as a frozen flow rack of minus 15 ° C. or lower must be used in the serving. However, large-scale merchandise is frequently introduced and the picking and packing line must sequentially take out the merchandise, so that it is difficult to keep such merchandise constantly in cold air. In addition, since the temperature zone for cold insulation has been demanded in detail according to the characteristics of the product, it is not possible to perform a catering operation in a cold storage room of a constant temperature zone such as a large-scale refrigerator. Furthermore, in a large-scale freezer room, human work is too severe because it is placed in a severe low-temperature environment.

  The present invention provides energy saving in a distribution center where a large amount of refrigerated and frozen products need to be accurately and efficiently cooled and stored in accordance with the temperature range according to the product characteristics and picked and picked frequently at random. A technology that can simultaneously solve problems such as efficient product cooling, improvement of work efficiency of complicated picking work, avoidance of cooling disease of workers, and the like becomes a problem.

  In the case of refrigeration equipment (flow rack or refrigeration / refrigeration rack booth) that temporarily distributes refrigerated and frozen products during product picking, specifically, the input port and the picking port are separately provided on the back and front sides of the rack booth. When it is provided, the internal refrigeration temperature can hardly be maintained and the refrigeration function may not be achieved due to the frequent opening and closing of the door. However, in order to make it easier to put articles into the racking booth, the back side of the rack booth needs to be as wide as possible. Similarly, in order to facilitate picking of articles, the front side of the rack booth needs to have a wide opening as much as possible. And it is necessary to unify the entry / exit route of goods in a certain direction.

  For example, Patent Literature 1 discloses a technical idea related to a large-sized refrigeration rack for efficient refrigeration storage and simple storage and retrieval of products. However, in this example, unless the opening front for entering and exiting the product is provided uniformly on the front side of the refrigeration rack, the product cannot be efficiently cooled and the energy efficiency for cooling cannot be fully exhibited. However, this is inferior in terms of workability because the articles are thrown in and picked out from the same frontage. That is, it has not reached the technique which solves the above-mentioned subject simultaneously.

Japanese Patent Laying-Open No. 2015-97560

  In the past technology or technical idea, a large amount of refrigerated and frozen products required by the logistics site are accurately and efficiently cooled according to the temperature range according to the product characteristics, stored, and taken out frequently at random. It was difficult to satisfy picking at the same time. The present invention, for the purpose of solving the above problems, efficient product cooling by energy saving at the distribution base of a large variety of refrigerated frozen products, improved work efficiency of complicated picking work, avoiding cooling disease of workers, etc. It is to provide a technology capable of simultaneously solving these problems.

In order to solve this problem, the freezing or refrigeration rack booth according to the present invention is
An article shelf consisting of a plurality of stages each provided with an entrance for taking out articles on the front side which is a picking work space and an entrance for entering articles on the back side of the picking work space;
A cold air outlet provided above (space) above the top of the article shelf;
The article shelf and the cold air outlet are provided in the same space, and a wall portion capable of interrupting exhaust heat due to heat exchange of a refrigerator or a refrigerator that generates the cold is provided. The cold air from the outlet of the cold air circulates from the top inner wall down the front inner wall to the rear inner wall via the bottom inner wall and circulates.

  The wall portion may surround a surface other than the bottom surface. The wall portion of the refrigerated or refrigerated rack booth is provided with an opening for taking out the article, an entrance for supplying the article, and an opening for discharging the exhaust heat. The cold air from the cold air outlet passes through the cold air flow gap from the upper part to the lower part of the article outlet of the article shelf, and further passes through the bottom surface of the article shelf to input the article. A circulation path that rises from the lower part of the frontage to the upper part is used. Heat other than the exhaust heat of the freezer or refrigerator can be discharged outside the freezer rack booth. The refrigerator or refrigerator is provided with an outlet for discharging the cold air and an opening for discharging the exhaust heat with the wall portion interposed therebetween.

  The refrigeration or refrigeration rack booth according to the present invention is a substantially rectangular parallelepiped freezing / refrigeration rack booth, and an article to be stored frozen has a slot on the back side and a slot on the front side for taking out the article. In addition, the first-in / first-out of the article can be smoothed by making the direction from the insertion to the removal of the article in one direction, and the freezing / refrigeration efficiency can be improved without disturbing the flow of the circulating cold air by making the movement direction of the article constant. .

  In addition, the cold air blowing direction of the refrigerator / refrigerator installed on the top of the inner wall faces the front side, and the cold air flows down from the ceiling to the bottom of the front wall, fills the bottom, and then becomes a rotating circulation that rises the back wall It can also serve as an air curtain at the time of taking out articles from the front opening, and it is possible to improve the cooling capacity by avoiding warm air inflow from the outside. In addition, the articles thrown in from the back are thereby gradually cooled, and can be taken out with the most stable cooling when taken out.

  In order to make the flow of the circulating cold air smooth, there is a gap from the front wall surface to the article shelf and a gap from the rear wall surface to the article shelf, and the gap between the side wall and the article shelf is minimized or closely adhered. Since the circulating cold air is heavy, it is the most efficient to flow downward, and the warm air that flows in from the outside and rises by flowing down the circulating cold air in the air curtain style at the front opening side with the highest opening and closing frequency. Efficient elimination can keep the internal cooling efficiency stable.

  The freezing or refrigerated rack booth according to the present invention is a strip-shaped sheet warmer in which the wall surface of the article take-out entrance is partitioned for each shelf of the article shelf, and has a width of 40 mm to 150 mm and a thickness of 2 mm to 5 mm. It can also be composed of a transparent sheet.

  The strip-shaped sheet warming has a width of 40 mm to 150 mm and a thickness of 2 mm to 5 mm, so that articles can be smoothly put into and taken out of the frozen or refrigerated rack booth. It is possible to prevent the internal cool air from flowing out to the outside when putting in and out the article, and to efficiently eliminate the inflow of warm air from the outside. The strip-shaped sheet warming is preferably about 100 mm in width, about 250 mm in length, and about 2 mm in thickness. The frozen or refrigerated rack booth according to the present invention is not limited to the material of the strip-type sheet warming, but is preferably a flexible soft vinyl chloride sheet.

  The refrigeration or refrigeration rack booth according to the present invention may be provided with a circulator on the bottom inner wall to reinforce the circulation flow of the cold air. A circulator is provided on the bottom surface of the freezing or refrigerated rack booth, and the circulating cold air that has flowed down from the upper part of the front surface is pushed out to the back side again, thereby improving the efficiency of the cold air circulation. It goes without saying that the cooling efficiency is most improved by rotating the flow of the circulating cold air without stagnation in one direction.

  The refrigeration or refrigeration rack booth according to the present invention is characterized in that the article shelf has a structure that is inclined downward from the article insertion entrance to the article take-out entrance.

  The multi-stage article shelf in the freezing or refrigerated rack booth is inclined from the back side to the front side, so that the articles are constantly pushed out to the front take-out front side and the work of the articles can be performed smoothly. In addition, since the article shelves are inclined in the direction in which the circulating cool air flows on both the front surface and the back surface, the circulation of the cool air is not disturbed, and the rotational circulation of the cool air can be promoted. The refrigeration or refrigeration rack booth according to an embodiment of the present invention is characterized by a one-way linear opening that replenishes products from the back side 3 of the refrigeration or refrigeration rack booth 1 and takes out the product pushed out from the front side 5. Having a frontage inevitably leads to first-in first-out correspondence of products.

  Moreover, the feature of the refrigeration or refrigeration rack booth according to one embodiment of the present invention is replenished by rotating and circulating the circulating cold air 8 injected from the unit cooler 2 from the inner top surface to the front surface, bottom surface, and back surface in a certain direction. The product is efficiently cooled and inevitably brought into the most cooled state when picking out. In other words, the direction of the cold air circulation and the moving direction of the commodities constitute the most efficient aspect in cooling. And since the side surface of the said article shelf is in contact with or close to the side wall of the freezing or refrigeration rack booth, the circulating cold air does not flow on the side wall side. Therefore, it is possible to improve the cooling efficiency of the refrigeration or refrigeration rack booth without disturbing the flow of the circulated cool air in one direction.

  According to the present invention, it is possible to provide an efficient refrigeration or refrigeration rack booth having good workability for loading and unloading articles, the best cooling efficiency for articles, and no waste of cooling energy. Further, according to the present invention, for efficient cooling of the goods in the rack booth, avoiding cooling disease to workers due to the overcooling operation of the refrigerator, etc., while significantly improving safety and workability Thus, a refrigerated or refrigerated rack booth capable of significantly improving economic efficiency is realized.

I have to.

  Inside the refrigerated or refrigerated rack booth 1, a plurality of display shelves 9 for displaying commodities are installed in such a manner that the back side is slightly raised and inclined downward toward the front side. The product replenished from the rear heat shield door 4 is placed on the display shelf 9 and pushed out to the front side 5 using the inclination of the shelf. In addition, the back side and the front side of the display shelf have a gap 14 for circulating cold air, and assist the circulation of the cold air. The left and right sides of the display shelf are in close contact with the inner wall of the refrigerated or refrigerated rack booth 1 (shown in FIG. 2).

  As shown in FIG. 1, a unit cooler 2 is provided on the internal top surface of the refrigeration or refrigeration rack booth 1 and supplies cooling air (circulated cold air 8). Further, a circulator 7 is provided on the inner bottom surface of the refrigerated or refrigerated rack booth 1 to push the circulation of the cold air in a certain direction to assist the flow of the cold air circulation.

  As shown in FIG. 1, the inside of the refrigeration or refrigeration rack booth according to an embodiment of the present invention is such that the cold air injected from the unit cooler 2 is directed to the front side along the inner wall of the refrigeration or refrigeration rack booth, It flows toward the bottom of the flow rack along the gap 14 of the front heating curtain 6. The circulating cold air 8 that has reached the bottom surface is then increased in force by the circulator 7 and rises upward along the back wall surface 3 and the gap 14 of the heat insulating door 4. As described above, the circulating cold air 8 is configured to rotate and circulate inside the refrigerated or refrigerated rack booth 1.

  In the refrigeration or refrigeration rack booth according to an embodiment of the present invention, the product display shelf 9 is inclined downward from the back surface 3 toward the front surface 5, so that heavy cold air is in the gap 14 in the front surface inside the refrigeration or refrigeration rack booth 1.
