Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for guiding fish between booths provided on a compare belt in a pretreatment process leading to a fish processing process.

Conventionally, in the pre-processing process for fish, manual work has been required not only to place the fish on a conveyor in a disorderly manner but also to align the fish heads horizontally.

Manually arranging large fish such as bonito and mackerel is easy, but when it comes to small fish such as sardines, the number of fish is large and it is necessary to arrange them accurately in the booths formed by partition walls on the running belt. It takes a lot of effort to do this,
It was also inefficient.

The present invention aims to solve this problem and smoothly guide fish to booths on a compare belt without manpower.

In order to solve this technical problem, we arranged a group of rollers in which a large number of rollers with spiral protrusions formed on their surfaces connected in parallel and endlessly on the side of the compare belt so that the booth and the rollers faced each other. The technical means is to run the belt at a constant speed in the same direction as the belt, rotate the rollers on the guide surface of the roller group, and place a backing plate on the opposite side of the conveyor.

According to this technical means, when a fish with its head facing toward the tip is placed between the loaves using an alignment machine or the like at the rear of the guide surface of the group of rollers running alongside the comparator belt, the rotation of the left and right rollers Since the directions are the same, the rollers are maintained by a balance between the force trying to enter between the rollers and the force trying to escape from between the rollers.

In this state, the spiral ridges of the roller move relatively toward the conveyor side due to the rotation of the roller, so the fish is It is carried over the rollers to the conveyor side.
The rollers face the booth, and the belt and rollers run in the same direction at the same speed, so the fish escapes from between the loaves and enters the booth, slipping inside the booth with its head on the backing plate. Collide and stop.

In the above action, in order for the fish to move forward between the rollers, the rollers must rotate in a direction opposite to the spiral winding direction of the protrusions in the direction of movement of the fish.

As described above, according to the technical means of the present invention, fish can be smoothly sent to the booth without resorting to human-force tactics, and
The heads can be aligned and arranged within the space, making it easier to perform subsequent processing steps.

Examples of the above technical means will be described below with reference to the drawings.

A free roller is used for each roller 2 constituting the roller group 1, and a pair of left and right sprockets 6, 6,
Both ends of the roller shaft 3 are fixed to chains 8 and 9 that are stretched between the rollers 7 and 7, and the roller group 1 runs and circulates in a direction perpendicular to the roller shaft 3, as shown by arrow a. Figure 1,
(See Figure 2).

As shown in FIG. 3, left-handed spiral protrusions 4 are formed on the cylindrical surface of the roller 2. As shown in FIG.

On the guide surface 10 of the loaf group 1 running alongside the running surface of the compare belt 11, a friction plate 5 supporting the surface of each roller 2, 2 is fixed to the support frame (not shown) of the roller group 1. , each roller 2, 2 receives resistance from the friction plate 5 on the guide surface 10 and rotates in the direction of arrow b.

Therefore, the protruding line 4 of the roller moves relatively to the belt 11 side, and the fish 15 held between the rollers 2 and 2 in the state shown in FIG. Facing above the booth 13 divided by the partition walls 12, 12, the backing plate 1
4, it stops and is arranged on the belt.

In this embodiment, when the convex stripes of the rollers are formed into a right-handed spiral, if a friction rod (not shown) is placed and fixed on the guide surface, each roller will rotate in the opposite direction to the traveling direction a of the roller group. , since the protrusions move relatively toward the belt side, similar effects can be obtained.

Of course, the driving of the roller group may be the same in order to maintain the roller group and the belt in the same direction and at a constant speed, or may be adjusted by separate driving.

In the above embodiment, each roller is rotated on the guide surface using friction plates and friction fins, but in order to speed up the rotation of the rollers, these plates and fins are constructed of belts and run as a friction belt. All you have to do is let it happen.

Alternatively, instead of using the free ridge roller shown in the example, a sprocket may be fixed to the roller shaft and a separately prepared chain or rack may be engaged to rotate the roller.
Other known rotational force applying means may also be used.

The distance between adjacent rollers may be determined based on the size of the fish, and the distance between the backing plate and the belt may be determined by taking into consideration the width of the fish's head to be cut off.
