Abstract

PROBLEM TO BE SOLVED: To enable a sufficient amount of moisture or sludges discharged out of some frozen items dropped onto the upper surface of a lower running section of a belt to be discharged, to enable damages of a pulley caused by these moisture or frozen items of sludges to be prevented and further to make a sanitary state of a belt conveyor device. SOLUTION: A diameter of each of a pair of pulleys 5a, 5b around which an endless conveyor belt 4 is wound is made different from each other. A lower running section 4b in the conveyor belt is inclined toward a large diameter pulley 5a, the extremity end of a suction nozzle pipe 7 connected to a header 6 arranged in a width direction of the conveyor is placed near an upper surface of a location where it becomes a lower position of the lower running section and then the header is connected to a suction machine 8.

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. In addition, bacteria are likely to be generated in the accumulated water and residue, which is unsanitary.

[0005]

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 of the freezing chamber according to the present invention, the diameter of the pair of left and right pulleys that rotate the endless conveyor belt are made different, so that the lower running portion of the conveyor belt is inclined toward the large diameter pulley side. The upper surface of the lower position of the lower traveling part is made to face the tip of the suction nozzle pipe connected to the header provided in the width direction of the conveyor, and the header is connected to the suction device. .

[0006]

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 different diameters, so that the upper traveling portion 4a is horizontal, but the lower traveling portion is inclined downward toward the large diameter pulley 5a.

However, at the lowered lower position in the lower traveling portion, the header 6 is provided across the width of the belt conveyor so that the tip of the suction nozzle pipe 7 connected to this header is exposed and the header 6 is sucked. It is connected to the machine 8.

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 frozen product.

[0010]

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 tilts toward the large diameter pulley. Therefore, the dropped water and debris flow down to the low position on the large diameter pulley side.

Since the tip of the suction nozzle pipe 7 connected to the suction device 8 through the header 6 is exposed at the low position, water and debris flowing down to the low position 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 no abnormal noise will be generated or the pulley will be damaged due to the ice being caught.

Further, since water and residue are not accumulated, little bacteria are generated, or even if there are few bacteria, there is little and it is hygienic.
