Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incision processing device for automatically and continuously incising the large intestine of animals such as pigs for meat.

[0002]

2. Description of the Related Art As an apparatus for incising the large intestine of an animal, the applicant of the present invention has filed prior applications of Japanese Patent Application Nos. 4-362003 and 5-124599. These devices basically include a guide rod for inserting the animal large intestine, a rotary transfer mechanism provided above the guide rod for sandwiching the animal large intestine and transferring it to the rear, and incising the animal large intestine to be transferred. It is composed of a rotary blade and was developed for the purpose of automatically and promptly and continuously performing an incision process on an animal large intestine, which was conventionally performed manually.

[0003]

By the way, since the intestinal tracts of animal large intestine are fastened together with a thin film of oil and fat, this adheres to the cutting blade to make the blade less sharp and generate resistance. There is a risk that the large intestine may be caught in the rotary shaft of the incision blade, the pulley in the rotary transfer mechanism, or the like. It is an object of the present invention to provide an animal large intestine incision device capable of automatically and promptly performing an incision process on an animal large intestine and preventing entrapment in the device.

[0004]

Therefore, according to the present invention, a guide rod for inserting the animal large intestine, and a rotary transfer mechanism provided above the guide rod for nipping the animal large intestine and transferring it to the rear are transferred. In an incision device for an animal large intestine having a rotary blade for incising an animal large intestine, the rotation transfer mechanism is stretched between a gear provided on a guide rod, a drive pulley and a driven pulley, and the gear and the teeth are provided. And a transfer belt that is formed with a concavo-convex shape that is formed so as to incline upward and rearward of the guide rod, and immediately after the gear provided on the guide rod is projected upward from the guide rod. With
It is provided with a convex portion having an inclined surface that comes into contact with the transfer belt.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a side view of a main part, FIG. 2 is a front view of the main part, and FIG. 3 is a plan view of the main part of an animal large intestine incision device according to the present invention.

As shown in FIGS. 1, 2 and 3, a water tank 2 is provided below the incision device for the large intestine of an animal. An incision processing unit 1 is provided facing the water tank 2. This incision processing unit 1 is provided with a guide rod 3 into which an intestinal tract of an animal large intestine is fitted, a rotary transfer mechanism 4 provided above the guide rod 3 to transfer the intestinal tract backward, and provided at a side of the guide rod 3 to be transferred. It is composed of a rotary blade 5 that incises the incoming intestinal tract.

The guide rod 3 is formed into a pipe shape so that water (hot water) or a fluid (water in this embodiment) in which a gas such as air is mixed can be passed through, and a spherical intestinal tract is provided at the tip thereof. The insertion portion 3a is provided, and the ejection hole 3b for ejecting the above-mentioned fluid or the like is formed so that the dirt in the intestinal tract can be washed out.

The rotary transfer mechanism 4 is stretched between synthetic resin gears 6, 7 and 8 provided on the upper surface of the guide rod 3 and a drive pulley 9 and a driven pulley 10 provided above the guide rod 3. The transfer belt 11 is composed of a rubber-made transfer belt 11 which is formed on the gears 6, 7 and 8 and meshes with the gears 6, 7 and 8 and is rotated by a motor (not shown) provided in the main body of the apparatus. The intestinal tract fitted to the guide rod 3 is sandwiched and engaged with each other (clockwise in FIG. 1) to rotate. Then, the intestinal tract transferred to the rear by the rotary transfer mechanism 4 is incised by the rotary blade 5,
It is opened and falls into the water tank 2. The drive pulley 9 is provided above the driven pulley 10, and the transfer belt 11 is inclined toward the upper rear of the guide rod 3. Further, the driven pulley 10 has a swing lever 10a.
Is rotatably supported on a fulcrum 10b through a coil spring 10c and an adjusting screw 1 is attached to the swing lever 10a.
0d are provided so as to be orthogonal to each other so that the pressing force between the unevenness of the transfer belt 11 and the gears 6, 7 and 8 can be adjusted. Here, 11a is a tension pulley, 11b is a tension lever, and the coil belt 11c can always keep the transfer belt 11 at the same tension.

The rotary blade 5 is arranged so that its tip is located in a guard plate 3c provided on the side of the guide rod 3, and the rotary blade drive motor 5 is provided via a rotary blade drive shaft 5a.
connected to b (counterclockwise in FIG. 1)
Rotate.

A safety cover 5c is attached to the side of the rotary blade 5 so as to be curved from above, and the intestinal tract after incision adheres to the rotary blade 5 and is lifted and wrapped around the shaft of the rotary blade 5. It is designed so that it can be prevented. Immediately after the gear 8 provided on the guide rod 3, there is provided a convex portion 12 that projects upward from the guide rod 3 and has an inclined surface 12a that comes into contact with the transfer belt 11 and makes an incision. The large intestine can be prevented from being caught in the gear 8.

Next, the operation of this embodiment will be described.
First, when one end of the massive intestinal tract in the water tank 2 is manually supplied to the tip of the guide rod 3, the gear 6, which is the rotation transfer mechanism 4,
It is nipped by 7 and 8 and the transfer belt 11 and transferred to the rear. The fed intestinal tract is incised by the rotary blade 5 which rotates counter to the traveling direction of the rotary transfer mechanism 4. At this time, the dirt in the intestinal tract is washed off by the water discharged from the ejection holes 3b of the guide rod 3. Then, the intestinal tract incised by the rotary blade 5 is transferred to the rear end of the guide rod 3, separated from the incision surface, and falls into the water tank 2 again. As described above, the incision work is rapidly and continuously performed until the intestinal tract is incised over the entire length.

[0012]

EFFECTS OF THE INVENTION In the present invention, since the incision device for the large intestine of an animal is constructed as described above, it has the following excellent effects. (1) Since the rotary transfer mechanism is composed of the gear provided on the guide rod and the belt which is stretched between the drive pulley and the driven pulley and has the unevenness which meshes with the gear, the intestinal tract is secured. The intestinal tract can be prevented from being damaged or dropped from the guide rod, and the incision of the animal large intestine can be automatically and promptly performed. (2) The transfer belt is provided so as to be inclined rearward and upward of the guide rod, and immediately after the gear provided on the guide rod, the transfer belt has an inclined surface protruding upward from the guide rod and in contact with the belt. Since a convex portion is provided and a safety cover that is curved from above is provided on the side of the rotary blade, the incised large intestine is caught in the pulley or gear in the rotary transfer mechanism or wrapped around the rotary blade shaft. Can be prevented.
