Description

DETAILED DESCRIPTION OF THE INVENTION The present invention divides flat tanks installed in multiple stages into upper and lower parts of a contact freezer for land use or ships, and by raising and lowering the girder during cargo handling, the upper and lower flat tanks can be converted into contact freezers. They are located at the same position in the middle of the contact freezer to facilitate loading and unloading of frozen pans containing frozen crystals, and a door is installed in the opening in the front of the middle of the contact freezer. The present invention relates to a method for rationalizing loading in a contact freezer, which is characterized by reducing leakage of cold air as much as possible to save energy, and a device therefor.

Conventionally, this type of contact freezer has a power cylinder installed above the girder (for land use) or a power cylinder installed above the girder.
One tank (for ships) is installed on the left and right bottom of the girder, and a multi-tiered flat tank is fixed to the girder so that the distance between each flat tank is constant at a maximum of 1 i'17 m using bolts and nuts. When the girder reaches its highest position as shown in Fig. 6A, the gap between each flat tank is sufficient for carrying in frozen bread.
There is a known device that has the maximum gap suitable for carrying out, and the gap between each flat tank is equal to the height of the frozen pan when the girder reaches its lowest position as shown in Figure B. be. However, since the loading and unloading of frozen bread into and out of the gaps between flat tanks in the conventional device is generally done manually at low temperatures, each frozen bread weighs 10
It weighs up to 19 kg, and putting frozen bread in and out of a flat tank in a high place requires excessive labor. In order to do this, the step stools required at high places become a nuisance, and it is necessary to carry the step stools in addition to cargo handling.
In the low-lying area, the frozen bread must be carried in and out by lowering one's back or bending down, which also requires excessive labor. In addition, sometimes the surface of the flat tank and the bottom of the frozen bread freeze, and when the frozen bread is taken out, it is necessary to apply an impact with a crowbar or the like to remove the frozen part, but this work is necessary in the high and low places of the flat tank. There are disadvantages in terms of streamlining cargo handling, such as difficulty in carrying out the process.

Further, cargo handling operations to the north are performed by providing an opening 28 on the entire front surface of the contact freezer, so it is necessary to open the door installed in the opening for the automatic cargo handling device to enter the two-door space. As a result, there are various drawbacks in streamlining cargo handling, such as severe leakage of cold air and poor thermal efficiency.

However, in the present invention, a wire lobe is connected to the girder through the suspension pulleys or chain wheels on both sides and the lower end of the flat tank in the intermediate stage. Or, when the chain is frozen and the girder is operated upward, the front and rear balance pulley or chain wheel is pulled up by the wire lobe or chain installed on the hanging pulley or chain wheel.
When it reaches the uppermost level, the gap between the flat tanks above the middle level flat tank narrows, and when the gargoo reaches the top, the gap between the upper flat tanks becomes narrower. The lower flat tanks below the intermediate stage are placed in the middle of the contact freezer, and the gap between them is suitable for loading and unloading frozen bread, and frozen crystals are stored in each of the lower flat tanks. When the frozen pan is inserted and the Gargoo is lowered, the bottom flat tank contacts the spacer on the contact freezer frame, and each gap in the lower flat tank is at the height of the freezing pan. By descending until they are equal, the space between the upper flat tanks is made suitable for loading and unloading the frozen pans, and it is placed in the middle position of the contact freezer.
When loading and unloading frozen bread into the contact freezer, the upper and lower flat tanks are located in the middle of the contact freezer, which is convenient for loading and unloading.
It does not require excessive labor as in the past, and there is no need to install or remove a step stool, and the opening in the front of the contact freezer required for cargo handling only needs to be in the middle position.
Compared to conventional open holes throughout the entire surface, leakage of cold air during cargo handling can be significantly prevented, and the heat-insulating structure greatly increases thermal efficiency, making it possible to streamline cargo handling operations. Furthermore, since loading and unloading only needs to be carried out at the middle part of the front surface of the contact freezer, it is convenient for the introduction of automatic loading and unloading equipment.

The lowering of the girder 8 is stopped at the position where each gap becomes the maximum gap by controlling the power cylinder 11. This is to insert the bread 12. When the insertion is completed, the power cylinders 11 and 11 are further activated by the control panel, etc., and the girder 8 is lowered to the lowest position as shown in FIG. The height is made equal to that of the contact freezer 1, and freezing is performed using the contact freezer 1. Next, when carrying out the frozen bread, the power cylinder 11° 11 is used to raise the cigar goo 8, and the gaps between the upper flat tank 5A are the maximum gaps, and the gaps between the lower flat tank 5B are the maximum gaps between the frozen bread 12. At a position equal to the height of (FIG. 5B), the raising of the girder 8 is stopped, and the frozen bread 12 is taken out from the upper flat tank 5A which has reached the middle Qfiff of the contact freezer 1. When the removal is completed, the Gargoo 8 is further lifted up by the power cylinder 11.11 and raised to the highest level (Fig. 5A), and the upper flat tank 5A is lifted up with the minimum gap as described above. , the lower flat tank 5B maintains a maximum gap suitable for carrying out the frozen bread 12, and becomes an intermediate position of the contact freezer 1, and the frozen bread 12 is taken out from the flat tank 5B to complete the cargo handling work.

In addition, as a method of raising and lowering the flat tank 5A above the middle flat tank 50, there is also a method of using a power cylinder that raises and lowers the flat tank 5C separately from the power cylinder 11° 11 that lowers the girder 8 A. However, the present invention does not require any power from outside the labor cylinder 11.11 to lift the flat tanks 5A and 50 in the middle section, but it is less energy efficient and causes many breakdowns, resulting in cargo handling problems. It has little effect on rationalization.

In addition, in this embodiment, pulleys are used for front-back balance and lifting, but the lifting pulleys 22, 2 are used for the girder 8.
2, 22, 22 shafts 23. The direction of shaft support by 23 is 90°
By rotating the two pulleys in the same direction as the front and rear balance pulleys 21 and 21, each pulley can be changed to a chain wheel.
In that case, a chain is used instead of the wire ropes 26, 26.

Furthermore, as described above, the present invention can be easily attached to an existing contact freezer.
