Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cold storage device for a transportation vehicle, more specifically, a normal cool (refrigeration), a chilled (ice temperature), and a freeze (frozen) due to a difference in cooling temperature. After transporting cold-insulated products, which are roughly classified into three types, especially when they are delivered to small lots with wing-type trucks or light four-wheel trucks whose both sides are open, or temporarily at a collection / delivery center, etc. The present invention relates to a cold storage device for a transportation / delivery vehicle used for storage.

[Conventional technology]

Conventionally, a dedicated refrigerating car has been used exclusively for large-scale transportation of the same type of cold-insulated product, but this method is not suitable for small-lot transportation and delivery in which various products are mixed, especially for home delivery. For such small-lot delivery, conventionally, the product is stored in a dedicated box made of cardboard, and the three-door refrigerator (three-temperature refrigerator) having three cooling chambers corresponding to the above-mentioned three temperature zones mounted on the collection and delivery vehicle is used. ), The method of sorting and storing is done.

The above-mentioned conventional small-lot transportation method has many problems as follows.

Since the volumes of the three cooling chambers of a three-door refrigerator are fixed, when the products in the temperature range of 1 or 2 are concentrated, a room that cannot be filled with the product and a room with rattles are created, which is wasteful. That is, in the case of this method, unless the products in the three temperature zones are collected and delivered at the same rate, it is wasteful and the total cost is high, so that it is not profitable. Needless to say, the ratio of each product in the three temperature zones is different each time.

Cooling in a three-door refrigerator has a low cooling capacity because it is performed with a cold storage agent, and only products that have been pre-cooled can be transported. Therefore, there are restrictions on transportation time and transportation distance, and it is extremely difficult to maintain temperature especially in summer. Of course, it is not possible to control the temperature according to the number of items in each cooling chamber.

Each time the product is taken out, the door has to be opened and closed, which may raise the temperature in the refrigerator and adversely affect the product. In addition, since the product is placed in a cardboard box without heat insulation, the product may be damaged or its value may be lost if it is taken out of the storage for a short time.

Since the goods are mechanically sorted into three temperature zones at the collection center, the goods put in a container that may be damaged, such as a paper bag or a vinyl bag, are not handled and must be stored in a designated box. There is.

The present inventor has proposed a cooling unit described in Japanese Patent Laid-Open No. 63-41781 in order to solve the problems in these conventional transportation methods. That is, the cooling unit
A general refrigeration system including a compressor, a condenser, a heat exchanger, etc. is built in, and a large number of horizontally projecting racks are provided, and containers are placed on the racks. A cooling plate and a remote switch are installed for each rack.By sliding the container on the rack and pushing it in, the cooling plate prys the lid of the container and enters the inside of the container to cool the inside. The temperature is
The container is automatically set by pressing the remote switch as the container is pushed.

[Problems to be Solved by the Invention]

Therefore, the cooling unit described in the above publication is vertically long, and the containers are stacked on one side in multiple stages. Therefore, this cooling unit is forced to be used by being pressed against the side of the bed of the delivery truck on the side of the driver's seat, so that the use is inevitably limited, and the number of loaded containers, in other words, the transport capacity is limited. Further, since the installation is performed as described above, the worker has to get on the loading platform one by one when carrying out the detaching operation of the container and the like, and the working efficiency is poor. Furthermore, the containers used therein are all of the same size.

Therefore, the present invention is capable of performing container desorption operations and the like without boarding the loading platform, and has high work efficiency, and
An object of the present invention is to provide a cold storage device for a transportation delivery vehicle, which can effectively use a cargo bed, has high transportation efficiency, and can simultaneously use containers of various sizes.

[Means for Solving the Problems]

The present invention provides a movable main body incorporating a cooling mechanism such as a compressor, a condenser, and a heat exchanger, and on both side surfaces of the main body,
Evaporators that enter the case for storing cold-insulated products are made to project in the horizontal direction as appropriate according to the type and number of cases to be used, and the cases can be attached to and detached from the main body, and the evaporator installation surface can be attached to the loading platform. The two-sided open type cold storage device for transportation vehicles installed on the cargo bed in the horizontal direction, or a movable main body incorporating a cooling mechanism such as a compressor, a condenser, and a heat exchanger is provided. Cases for storing cold-insulated products are installed on both sides, and an evaporator is horizontally projected from the main body into the case as appropriate according to the type and number of cases to be used. The above-mentioned problems were solved by a double-sided open type cold storage device for a transportation delivery vehicle installed on a cargo bed so as to face in the direction.

[Action]

This device is equipped with one or several evaporators in the lateral direction on the bed of a transportation vehicle. The container is set on the device from both sides of the bed without the operator having to ride on the bed.
As a result, the evaporator enters the container and continues to cool the container to a predetermined temperature during transportation. The container is not limited to one type, and various types can be used at the same time.

〔Example〕

 A preferred embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows two types of the apparatus according to the present invention mounted on a small truck. In the figure, reference numeral 1 denotes a main body, and a base 2 is formed by projecting the bottom portion to both sides. A caster is attached to the base 2 so as to be movable. A cooling mechanism including a compressor, a condenser, a heat exchanger, and the like is incorporated in the main body 1. An appropriate number of evaporators 3 are horizontally projected on both sides of the main body 1. For example, one side has two rows and one row, the other side has two rows and four rows (front side in FIG. 1), one side has two rows and one row has two rows and four rows (both sides rear side in FIG. 1), and both sides have two rows. 1st stage (second
As shown in the figure), various variations are possible. Four
Is a 3 temperature band select switch consisting of 3 buttons.
One button corresponds to three temperature zones: cool, chilled, and freeze. The select switch 4 is a hard case 5 made of plastic or metal (see FIGS. 1 to 4), or
With a pressing element (usually a slide type in the case of the hard case 5 and a cutting type in the case of the foam case 6) provided in the foam case 6 made of Styrofoam (see FIGS. 1 and 6),
The cooling mechanism is controlled by being selectively pressed, thereby cooling the inside of the case to a selected temperature zone.

There are various shapes of the hard case 5, and as described above, the installation position and the number of the evaporator 3 and the select switch 4 are changed accordingly. The hard case 5 shown in FIG. 2 is vertically long, and the inside is divided into three chambers via a two-stage shelf 7, and a door 8 is attached to each chamber.
It goes without saying that the compartment is not limited to three rooms. Further, the shelf 7 is removable, so that the size of the room can be freely changed. The shelves 7 are provided with sufficient ventilation so that each room is cooled evenly. Although the illustrated door 8 is of a type in which it is pulled down to the front, it is needless to say that it may be opened laterally (see FIG. 4). The hard case 5 is provided with a handle 9 on its upper surface and / or side surface in order to facilitate carrying. A slit 10 into which the evaporator 3 can enter is formed on the back surface of the hard case 5. A force in the closing direction is constantly applied to the inside of the slit 10 by a spring, and a lid 11 that opens only on the inside by pushing against the spring is installed (see FIG. 5). In normal times, that is, when the evaporator 3 is not approaching, the slit 10 is closed by the lid 11. The hard case 5 of this type is arranged side by side with respect to the main body 2
4 pieces can be set on both sides of the main body 1.

The hard case 5 shown in FIG. 3 has the same width as the main body 1 and is of a type that is set in two stages on one side of the main body 1. In this case, the evaporator 3 and the select switch 4 of the main body 1 are also arranged in two stages. And further, the main body 1
A rack 12 for mounting the upper hard case 5 is attached to the side surface of the rack. The rack 12 may be a bent pipe as shown, or may be a plate-shaped member.

The hard case 5 shown in FIG. 4 has the same size as the main body 1 and is considerably large, so that it can be easily moved by attaching casters 13.

In any of the hard cases 5 described above, a connecting tool is provided between the hard case 5 and the main body 1 to prevent lateral displacement and the like.

In the example shown in FIGS. 2 to 4, the hard case 5 of the same type is set on both sides of one cooler, but different types of hard cases 5 can be set on both sides. What may be done is as described above. Further, as shown in FIG. 1, the hard case 5 and the foam case 6 may be combined. When the foam case 6 having the size shown in FIG. 1 can be set, the evaporator 3 and the select switch 4 are provided on one surface of the main body 1.
It will be installed at 8 addresses each. Further, a rack 12a similar to the rack 12 for mounting the foam case 6 is provided. It is preferable to prevent the foam case 6 from falling off by fitting the rack 12a into a groove (not shown) formed in the back surface of the foam case 6. In the case of the foam case 6, a rubber band 15 is laid around from the container 13 to the lid 14 (Fig. 6), and the horizontally long evaporator entrance 16 is normally closed. Then, as the evaporator 3 moves into the evaporator entrance 16 against the contracting force of the rubber band 15, the lid 14 is pushed up and the evaporator 3 enters the case. Denoted 17 to 19 are removable pushers corresponding to the freeze, chilled, and cool temperature zones, respectively, and the pushers corresponding to the desired temperature zone are removed.

Although the cooling device main body and the case are separable in the above-described embodiment, the hard case 5 and the main body 1 having the above-described configurations may be integrated. In that case, the select switch 4 is provided on the outer surface of the case, and the temperature zone is set manually.

When a plurality of the present devices are mounted on a vehicle, it is possible to use a battery, a power source such as a household power source, and a cooler in common so that the devices can be cooled simultaneously or sequentially. In such a case, the size and weight of the device can be reduced, and the load capacity can be increased accordingly.

In the case of transporting a cold-insulated product by this device, it is not necessary to store the cold-insulated product in a cardboard box as in the conventional case, and any package may be used. In the case of the hard case 5, it is possible to take in / out the cold-insulated product while it is still mounted in the vehicle, and it is also possible to deliver it together with the hard case. In the case of the foam case 6, it will be delivered in case units. In addition, in the case of this device, only the case or the main body device itself can be unloaded from the vehicle when not in use, and there is an advantage that it can be freely mixed with general luggage.

〔The invention's effect〕

The present invention is as described above, and when the present device is installed on the loading platform of a transportation delivery vehicle whose both sides are open, it is possible to detach the container from both sides without the work vehicle riding on the loading platform,
It has good workability and can be loaded with only the necessary amount of containers, so it is possible to set different types of containers in one device without waste, and efficiently keep cold-cold products regardless of their quantity and type. It can be loaded and transported. In addition, each case can be controlled to the desired temperature zone, and it can be freely mixed with general parcels, and it is possible to reduce the size and weight of the device and save energy, which contributes to the development of cold storage product transportation business. However, it has an extremely large effect.
