Description

[Detailed description of the invention] "Industrial application field" This invention divides the multi-stage flat tank in a horizontal contact type freezing device into three stages: upper stage, middle stage and lower stage, and the number of upper, middle and lower stages, respectively. This invention relates to a cargo handling rationalization device in a horizontal contact type freezing device, which positions the tiered flat tanks at waist height to streamline cargo handling operations.

``Prior Art'' Conventionally, horizontal contact freezing devices installed on fishing boats, etc. have a girder fixed to a pair of elevating means, and flat tanks connected to each other in multiple stages by hanging bolts suspended from the girder. In this device, when the elevating means is at its maximum extension, the distance between the flat tanks is maintained higher than the height of the frozen pan filled with the material to be frozen, and cargo is handled in each flat tank.

In addition, with the above device, cargo handling covers the entire flat tank from the feet to the overhead, so the cargo handling is over a wide range.
61-89779 etc. In this invention, both sides of the girder are fixed to a pair of first hydraulic cylinders, and cooling bodies ( Regarding a horizontal contact type freezing device in which a group of flat tanks (flat tanks) are suspended from a girder, a second piston is fixedly provided in the middle of the outer surface of the tube of the first hydraulic cylinder, and a second cylinder tube is fitted to the second piston. A second hydraulic cylinder is provided in the second cylinder tube so that the second cylinder tube moves up and down, and when the first hydraulic cylinder is in an extended state and the second cylinder tube is in a lowered position, the flat tank group When the cylinder tube of the second hydraulic cylinder is raised after the engagement actuation part is engaged with the flat tank group at a predetermined height position, the engagement actuation occurs. The moving part is raised while engaging the lower part of the group of flat tanks, the lower part of the group of flat tanks is lifted, and in this state, the pan is placed on the lower part of the group of flat tanks, and the cylinder tube of the second hydraulic cylinder is lowered. After the engagement of the engagement actuating portion is released and bread is placed on each of the upper flat tanks, the first hydraulic cylinder is shortened and frozen.

``Problems to be solved by the invention'' In the former horizontal contact type freezing device of the prior art, cargo handling is carried out over the entire surface of the flat tank from the feet to the top of the tank. Lifting heavy objects over one's head over a long period of time, which involves unnatural and repetitive movements, is hard work and can easily cause back pain. In addition, the heat-insulating door on the entire surface of the horizontal contact type freezing device needs to be fully opened during cargo handling, and during this time the cold air inside the freezer leaks into the cargo handling passage, not only worsening the working environment, but also preventing cold air from leaking from inside the freezer. There are problems such as causing a decrease in efficiency and being undesirable from the viewpoint of energy saving. Furthermore, in 1988,
Although the idea of No. 89779 has the advantage of reducing cargo handling to the lower part of the flat tank group, there is no consideration given to cargo handling to the upper part of the flat tank group.
There is a problem in that comprehensive rationalization has not been achieved, and furthermore, the mechanism and hydraulic equipment of the hydraulically operated device are complicated, leading to higher costs.

"Means for Solving the Problems" This proposal was created to solve the above problems.
This will be explained using figures.

As shown in FIGS. 1 to 4, the ends of the main cylinders 2a and 2a of the main cylinders 2 and 2 of the lifting means installed on the frame 3 on both sides of the girder 1 are fixed, and the ends of the rods 2a and 2a are fixed to the girder 1 as shown in FIG. The 16 flat tanks 4 are suspended via the suspension bolts 5, 5 so that the effective number of loading stages is 15, and the rods 2a, 2a of the main cylinders 2, 2 are suspended.
2a is raised to make the space between the vertically adjacent flat tanks 4, 4 higher than the height of the frozen bread 6 filled with the material to be frozen, and the frozen bread 6 is carried in between the flat tanks 4, 4, In the horizontal contact type freezing device that carries out the frozen bread 6 from between 4 and 4, the multi-stage flat tank 4 is divided into three stages of 5 stages each: an upper stage, a middle stage, and a lower stage, and among the 5 middle stage flat tanks 4, Pull up the lifting fittings 8, 8 that pull up both sides of the lowermost flat tank 4a.

When extended, the top five flat tanks 4 are at waist height, making it easy to carry in the frozen bread 6. Next, as shown in Fig. 2, when the rods 2a, 2a of the main cylinders 2, 2 and the rods 9a, 9a of the sub cylinders 9, 9 are both extended to the maximum, the flat tank 4 in the middle 5th stage will be at a height above the waist. Therefore, the frozen bread 6 can be transported in the same way. Furthermore, as shown in FIG. 3, the rods 2a, 2a of the main cylinders 2, 2 remain at maximum extension,
When the rods 9a, 9a of the auxiliary cylinders 9, 9 are reduced to the minimum, the flat tanks 4 in the middle and higher stages are lifted up and the lower five flat tanks are brought to above waist level, so the frozen bread 6 is carried in in the same way. be able to. When the loading is completed, the rods 2a, 2a of the main cylinders 2, 2 are reduced as shown in FIG.
The distance between the two is equal to the height of the frozen bread 6, and each frozen bread 6 can be brought into pressure contact with the upper and lower flat tanks 4, 4 to be in a frozen state. When carrying out the frozen bread 6, from the frozen state shown in FIG.
When the rods 2a, 2a of the main cylinders 2, 2 are extended to the maximum, it becomes possible to carry out the frozen bread 6 from the top of the lower five flat tanks 4 at the waist-high position as shown in FIG. Rod 2a,
If the rods 9a, 9a of the sub-cylinders 9, 9 are extended to the maximum while keeping the rods 2a at the maximum extension, it becomes possible to carry out the frozen bread 6 from the top of the middle five-stage flat tank 4 as shown in Fig. 2. Further, the rods 2a, 2a of the main cylinders 2, 2 are reduced to the minimum size, and the rods 9a, 9a of the sub cylinders 9, 9 are pulled up at the tips of the metal fittings 8, 8 to the uppermost level flat tank 4b of the several stages of lower flat tanks 4. When the frozen bread 6 is contracted to a slightly extended state so as to come into contact with the container, it becomes possible to take out the frozen bread 6 from the upper five flat tanks 4 as shown in FIG.

Spacers 21 and 21 are attached to the lower surface of the girder 1 and the upper surface of the pedestal 3 to prevent the uppermost and lowermost flat tanks 4 from coming into direct contact with the girder 1 and the pedestal 3.

"Effect of the invention" This invention has the above configuration, and the main cylinders 2, 2
By expanding and contracting the rods 2a, 2a and 9a, 9a of the auxiliary cylinders 9, 9 as described above, the five flat tanks 4 are placed on the same waist in order of upper stage, middle stage, and lower stage during transport. At the time of unloading, the five tiers of flat tanks 4 are sequentially positioned at the same height in order of lower, middle and upper tiers for cargo handling.
This allows for rationalization of cargo handling work.

In addition, since cargo handling can be carried out at the same height above the waist, there is no need to fully open the heat-insulating door on the front of the horizontal contact type freezing device, and only the area above the height needs to be opened. Leakage of cold air inside the freezer is reduced, reducing deterioration of the working environment and reduction in refrigeration efficiency, and also making it possible to save energy.

Furthermore, by simply adding the sub-cylinders 9, 9 to the girder 1 of the present invention, the mechanism of the hydraulically operated device is simplified as much as possible, making it possible to provide an inexpensive device that is easy to handle due to the simple configuration of the hydraulic circuit. .
