Description

[Detailed description of the invention] This invention is used in an animal skinning machine that is used to remove unnecessary skins when processing food animals such as fish and chickens, and is used to press animal meat during the skinning process. This invention relates to an improvement of a presser device used for.

This type of peeling machine has recently come into widespread use because it can quickly and rapidly peel a large amount of skin.

The outline of this peeling machine will be explained with reference to FIG. 1. 1 is a toothed feed roller with serrated teeth facing in the direction shown, and 2 is a toothed fall roller with serrated teeth facing in the opposite direction to the toothed feed roller 1. These rollers 1.degree. 2 are pivotally supported by a frame 3, and are driven to rotate at a reduced speed in the direction of the arrow shown in the figure by a drive section 4 such as an electric motor via a deceleration shaft 5 and a chain 6.

In addition, 7 carries the fish, etc. to be peeled by the toothed feed roller 1.
8 is a feeding device for feeding skinned fish, etc., 9 is a knife for skinning, 1
0 is a knife stand that supports this knife 9, 11 is a tension sprocket, and 12 is a cleaning device that spouts jet water.

The toothed feed roller 1 and the fall-off roller 2 are elongated in the axial direction (direction of the paper), and the feed roller 1 has circumferential grooves at appropriate widths of teeth in the axial direction, while the fall-off roller 2 has teeth at positions corresponding to the circumferential groove of the feed roller 1,
These teeth are disposed on the feed roller 1 so as to fit into the circumferential groove.

For example, in the case of peeling the outer skin of fish carp using this peeling machine, the fish carp, which has been made into a fill type or dress type in advance, is fed along the feeding device 7 to the toothed feed roller 1, and the fish carp is fed through this feed. The serrations of the rollers 1 in the direction shown in the figure transport the meat in the direction of a skinning knife 9, the skin of which is removed by the knife 9, and the meat is sent out along the delivery device 8.

The peeled outer skin of the fish oyster falls downward from the gap between the feed roller 1 and the knife 9, but some of the outer skin adheres to the feed roller 1.

However, since the feed roller 1 is circumferentially surrounded by a fall-off roller 2, the fall-off roller 2 brushes off the outer skin of the fish adhering to the feed roller 1.

At the same time, jet water is jetted from the cleaning device 12 to clean the feed roller 1 and fall roller 2. In this peeling machine, when the toothed feed roller 1 feeds the fish to the skinning knife 9, the fish is If the fish floats on the surface of the roller 1, it will not be possible to remove the skin, so a holding device 13 is provided to press the fish against the surface of the toothed roller 1.

In the conventional presser device 13, a plurality of presser blades 14 whose lower ends are curved in the feed direction are arranged side by side in the axial direction of the feed roller 1 in a circumferential groove thereof, and the feed roller 1 is moved by a spring 15.
These pressing blades 14 are elastically biased in the direction of the roller 1.
The feed roller 1 is configured to fit into the circumferential groove of the feed roller 1, and its elasticity presses the fed fish against the circumferential surface of the feed roller 1.

However, since this conventional presser device 13 has a plurality of rod-shaped presser blades 14 arranged side by side, the structure for attaching the framework and the structure for imparting elasticity by the spring 15 are complicated, and the spring 15 is the object to be peeled. It is necessary to make adjustments depending on whether the food is fish, chicken, pig, or beef, but this adjustment is troublesome.Furthermore, this presser device 13 does not have a feeding function, so if the pressing force is too strong, the feed roller 1 This has the disadvantage that it impairs the feeding operation.

In view of the above-mentioned points, it is an object of the present invention to provide a holding device for an animal skinning machine, which has a toothed roller type structure and eliminates the above-mentioned drawbacks.

An embodiment of the present invention will be described below.The presser device of the present invention has a rim 22 having triangular teeth 21 on its outer circumferential surface and a boss 24 having a shaft hole 23, as shown in FIG. A toothed presser roller 27 made of a gear-shaped rubber material connected by a plurality of diagonally moving arms 26 is arranged so that several appropriate spaces 25 of approximately the same shape are arranged in the circumferential direction between the two members 22 and 24. As shown in FIG. 3, a plurality of them are stacked and fixed in the axial direction on a rotating shaft 31 with gaps provided between them.

Reference numerals 32 and 32 indicate pulleys fixed to the rotating shaft 31.

As shown in FIGS. 4a and 4b, the presser foot device has support members 34 and 34 respectively provided from a pair of pillars 33 and 33 erected from the frame 3, and the tips of these support members 34 and 34 are connected to the presser foot. The 227th group is rotatably supported at both ends of the rotating shaft 31, and the 27th group of embossing rollers is disposed parallel to the toothed roller 1 and close to it from above.
A drive shaft 35 is rotatably inserted between 3.degree.
32, and one end of the drive shaft 35 is connected to a drive unit 40 by a belt 39 via a pulley 38, and the decelerated rotation of this drive unit 40 is applied to the group of presser rollers 27 via the drive shaft 35. The peeling knife is rotated in the direction of 9 in synchronization with the toothed feed roller 1.

In this case, as shown in FIG. 2, the arm 26 is disposed in an oblique manner such that the rim 22 side thereof leads in the rotation direction.

Further, the supporting members 34, 34 are made of an elastic material so that the rollers 27 can swing up and down when the rollers 27 bite an animal.

The drive section 40 may be the drive section 4 shown in FIG. 1, or may be provided separately.

In the device according to the present invention, the supporting members 34, 34 supporting the toothed press roller 27 are vertically swingable, and the toothed press roller 27 itself is made of an elastic body of rubber material, and moreover, the toothed press roller 27 itself is made of an elastic body made of rubber material, and moreover, the toothed press roller 27 is made of an elastic body made of rubber. 27 are individually arranged in parallel in the axial direction, and the group of presser rollers 2γ moves obliquely with its arm 26 leading in the direction of rotation with the rim 22 side, so that it can hold down animals such as fish. At this time, the support members 34, 34 swing upward and the holding roller 27 bends, so that each part of the irregularly shaped animal can be elastically held down in its shape. Since the group of rollers 27 is rotationally driven in the direction of feeding the animal toward the knife 9, it also functions in cooperation with the feeding roller 1 to feed the animal.

That is, unlike the conventional method in which a spring 15 is attached to a presser for an animal, the support member 34, 34 made of an elastic body and the flexure of the presser roller 27 themselves are used. A force adjustment mechanism is not required, and the structure is simple and simple.

Further, the presser roller 27 has teeth 21 and is rotationally driven in the direction of feeding the animal toward the knife 9 side, so it serves both to press and feed the animal, so it can perform the skinning operation regardless of the presser force. It will be possible to proceed smoothly.

In the above embodiment, it is preferable to use a hard oil-resistant rubber material as the presser roller 27.

This is because oil-resistant rubber materials do not melt even after long-term use, which is preferable in terms of food hygiene.

In addition, it is better to prepare pressure rollers 27 with different degrees of deflection, and to use them interchangeably depending on whether the material to be peeled is fish, chicken, pigs, cows, etc.
is running obliquely, so changing the direction of rotation will change the degree of deflection. Therefore, even if the presser roller 2T is the same, if the arm 26 is installed so that it runs obliquely in the opposite direction to the direction of rotation,
This is convenient because two degrees of deflection, strong and weak, can be obtained.

Further, in the above embodiment, an example was explained in which the group of presser rollers 27 is forcibly driven to rotate, but in this case, the group of presser rollers 27 can be freely rotated without being forcefully driven to rotate. Since rotation inevitably rotates in the feeding direction, a sufficient feeding function can be expected.
