Abstract

PROBLEM TO BE SOLVED: To provide a hygienic, freezing room belt conveyor device capable of sufficient disposal of water or refuse from a frozen article falling on the upper surface of the lower traveling part of a belt and preventing damage caused by the water or the refuse of the frozen article to a pulley. SOLUTION: A conveyor pressing roller 12 is provided in the upper surface of the lower traveling part 4b of an endless conveyor belt 4 rotary-traveled horizontally by a pair of left and right pulleys 5a and 5b having identical diameters so as to travel the lower traveling part 4a in a slow V shape. A suction nozzle tube 7 connected to a header 6 provided in the width direction of the conveyor is placed to face the upper surface of the lowest position of the lower traveling part and the header is connected to a suction machine.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a conveyor for transferring goods in a freezing apparatus.

[0002]

2. Description of the Related Art A conveyor device of a steel belt freezer that conveys an item such as fish meat to a freezing chamber and freezes the item while passing through the freezing chamber is shown in FIG. The upper and lower traveling parts of the belt 4 can be kept horizontal by 5, 5 and,
Further, guides 9 for preventing meandering are provided on both side edges of the belt 4.
Is attached endlessly.

In such a conveyor device, water and debris discharged from the frozen material are the back surface (upper surface) of the lower running portion of the belt.
Accumulate in The accumulated water and debris may freeze, and the frozen material may get caught in the pulley and make an abnormal sound, or may damage the belt.

In order to prevent this, the scraper 13 is provided in the lower traveling portion as shown in FIGS. 4 and 5, but the guide acts as a bank, and water and debris on the lower traveling portion are sufficiently provided. Could not be discharged.

Further, various bacteria are easily generated in the accumulated water and residue, which is unhygienic.

[0006]

The present invention has made it possible to provide a belt conveyor device for a freezing chamber in which such problems are solved. Therefore, the belt conveyor device for a freezing chamber according to the present invention has a V-shaped lower traveling portion on the upper surface of the lower traveling portion of the endless conveyor belt which is horizontally rotated by a pair of left and right pulleys having the same diameter. The conveyor push-down roller is installed so that it can travel in a straight line, the tip of the suction nozzle pipe connected to the header provided in the width direction of the conveyor faces the upper surface of the lowest position in the lower traveling section, and the header is sucked. It has a structure connected to the machine.

[0007]

Embodiments of the present invention will be described below with reference to specific examples shown in the accompanying drawings. In FIG. 1, reference numeral 1 is a low temperature freezing chamber provided with a cooler 2, and 3 is a steel belt conveyor device.

The pulleys 5a and 5b at both ends of the belt conveyor 4 in the conveyor device have the same diameter, and therefore the upper traveling portion 4a and the lower traveling portion 4b are originally designed to be horizontally movable.

However, in the apparatus of the present invention, the belt lowering roller 12 is provided on the upper surface of the lower traveling portion so that the lower traveling portion of the conveyor belt can travel in a gentle V-shape, and The tip of the suction nozzle pipe 7 connected to the header 6 provided across the width of the belt conveyor is faced on the upper surface of the lowest position of the side traveling portion, and the header 6 is connected to the suction device 8. is there.

Reference numeral 9 is a meandering prevention guide provided on both side edges of the belt conveyor, 10a and 10b are pulley shafts, and 11 is a product to be frozen.

[0011]

In this embodiment, the water and residue from the frozen products such as fish meat fall on the lower running part of the belt conveyor, but the lower running part is pushed down by the roller 12. Since it falls, the water and debris that fall down flow down to the low position.

Since the tip of the suction nozzle pipe 7 connected to the suction device 8 through the header 6 is exposed to the low position portion, water and debris flowing down to the low position portion are sucked by the suction nozzle pipe. It is discharged and no water or residue accumulates in the low position.

Therefore, the water and the residue will not be frozen and the ice will not be caught in the pulley, and the abnormal sound will not be generated and the pulley will not be damaged due to the ice being caught.

Further, since water and residue are not accumulated, there is little or no generation of miscellaneous bacteria, and even if there is little bacteria, it is hygienic.

Further, since the pulleys at both ends have the same diameter, they can be provided at the same height position, there is no trouble in adjusting the height, and the same standard is sufficient. Also in terms of cost, it is more economical than those with different diameters.
