2. Description of the Related Art Due to the recent improvement of eating habits and diversification of tastes, there are an extremely wide variety of foods that must be stored in a warehouse, and the storage temperature varies. Is generally narrow and varies from drug to drug. Moreover, in many cases, it is necessary to store such a large variety of products little by little, which necessitates a huge warehouse, resulting in an increase in operating costs and measures against dew condensation.

In particular, when goods are carried in and out of a cold-storage warehouse, the door of the warehouse is usually opened and a truck, a forklift or the like is loaded into the warehouse if necessary, and an overhead crane or a conveyor provided in the warehouse is installed. The loading and unloading of goods is carried out by the human resources of workers who use it, and the temperature inside the warehouse changes due to outside air entering the temperature-controlled warehouse or exhaust from trucks and forklift trucks entering and leaving the warehouse. There is a risk that it will adversely affect the freshness of the stored products.

Further, since there are many kinds of small quantity products, there are many problems in the sorting work associated with loading and unloading in the warehouse. For example, when the produced products are kept cold, the cold sorting is done in the cold storage room, and then the small sorting is carried out. Then, the products to be delivered are moved to the shelves at the delivery port in advance so that a large amount can be delivered at one time when the products are delivered, and cold work, which is a health problem, takes time.

[Problems to be Solved by the Invention]

Recently, there has been considered an automatic warehouse that should solve this problem, but the purchase cost, operating cost, and maintenance cost are also high, and it takes time to sort out a large number of small items of small items. There is also a problem in terms of efficiency, such as excessive cost. Further, a method of sorting in a closed type cool box partitioned by shutters and the like as disclosed in JP-A-3-31102 has been considered, but in the case of such a method, a door opening / closing mechanism Since there are many parts and components, there are many mechanical troubles, the outside air enters and the air balance deteriorates, the cooling effect decreases, and it is difficult to prevent dew condensation, and not only equipment costs but also operating costs become expensive. In addition, there is a problem that it is difficult to change the layout.

The present invention has been made in view of the above circumstances, and it is possible to easily and surely perform temperature control and sorting of a variety of small-lot products that need to be kept cold or warm without any health problems. We provide a temperature control method for high-mix low-volume products that can streamline sorting work and efficiently keep cold and warm, and a method for sorting cold and warm products by a data display device that displays sorting data necessary for sorting work. The purpose is to.

[Means for Solving the Problems]

The present invention has been conceived in order to achieve the above-mentioned object, and in a building in which a product that needs to be kept cold or warm is stored, a primary cold keep is provided as an adjustment between the manufacturing process or the packaging process and the sorting process. A cool or warm air generator and a cold or warm air outlet in the sorting process, or an opening-type cool warehouse or a warming / cooling product that uses a warming / warm temperature control method and sorting data necessary for sorting work. A method of sorting cold and warm products by a data display device that displays.

[Action]

According to this, after the production, primary cooling or heating is performed, and at the same time, the production line and the sorting process are balanced (buffering), and after the small sorting, the secondary cold insulation or heat insulation is performed by the open type cold storage or warm storage. However, since the small sorting work can be performed according to the display of the sorting data display device, the line speed of the front and rear processes can be adjusted, and since there is no opening / closing of the door, there is no disturbance of the cold insulation, and the temperature can be constantly controlled.

【Example】

The present invention will be described with reference to the case of cold storage in one embodiment shown in the drawings. FIG. 1 is an overall configuration diagram showing an embodiment in which the present invention is embodied, and FIG. 2 shows a downflow type cold storage with a display for sorting according to the embodiment.

First, the produced product is stored in a large refrigerator (not shown), a required amount of the product is taken out in accordance with the order, the product is packaged in the packaging line 5, and then the primary cold storage 6 keeps it primary cold. At the same time, the line between the packaging line 5 and the sorting process is balanced (buffering), and the product is displayed by the sorting data display device including the sorting display 10 installed on the upper part of the downflow type cold storage box 14. Are subdivided into the containers 22 for each delivery destination, the containers 22 are mounted on the container cart 12, the cart 12 is transported to below the cold air outlet 18 of the cool box 14, and the product is secondary in the cold air flow 18. It is kept cool, and at the time of delivery, the dolly 12 is transported to the pre-shipment chamber 16 for preventing dew condensation due to the inflow of outdoor air and for keeping the shipped products cold or warm. From loading the truck, to transport the goods to the destination.

As one embodiment of the present invention, as a sorting data display device 10, a sorting support device as disclosed in Japanese Patent Application Laid-Open No. 270714, that is, sorting data is searched and memorized by a conventional slip or the like. No need to
By using a sorting support device that mechanically removes a specified product, it can be sorted easily and without forgetting to take it out, the burden on the operator can be reduced, and the distribution time can be shortened. You may use the sorting data display device marketed in.

Further, as a more effective cooling method, a cold air collecting method of an access floor structure in which a cold tunnel is provided to provide cold air by providing a tunnel below a position where the vehicle 12 is conveyed below the cold air outlet 18 can be considered.

Here, the cooling method by the seed sowing method mainly using the downflow type opening type cold storage was explained as an example, but it can also be applied to the storing by the picking method, and the upflow type opening type cold storage warming box is used. If used, it can also be used for heat retention.As an application of the cold insulation method, instead of the downflow method, it is also possible to use an air flow that descends the surface of the product using the specific gravity difference, and to further improve the work efficiency by the picking method. It is also possible to install a conveyor device, an automatic carrier station, a carousel, a car, a container car, etc. in the sorting area and the cold storage.

【The invention's effect】

According to the temperature control method for a cold-insulated or warm-insulated product and the sorting support device for the same according to the present invention, since the cold-insulated warehouse or the warm-insulated warehouse is provided between the steps, the line speed of the preceding and following steps can be adjusted. Also, because the sorted products are stored in an open-type cool box or warm box, there is no need for a huge warehouse, expensive facility costs, operating costs, and maintenance costs are not required, and it is not desirable for health when cold. Severe labor in extremely cold climates has been eliminated, and health and labor problems that were previously unavoidable can be solved all at once.Because there is no closed type cold insulation or heat insulation system, there are no problems with the door opening and closing device, and Since the system uses a display to enter or exit, it can shorten the time required from loading and unloading to product shelves or from sorting to shipping and loading. Cold room or the like effect even without thermal insulation chamber structure in order to maintain the cold or warmth of the condensation prevention and shipping items that are great.
