DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a peeling treatment apparatus used for peeling an epidermis from a slaughtered animal such as a cow.

[0002]

2. Description of the Related Art Slaughtered animals such as cattle (hereinafter, referred to as cattle)
Called "carcasses". For example, in the peeling process for peeling (peeling) the skin from the lower side (carcass head side) of the carcass suspended in the air from the upper side (carcass head side), There is a peeling treatment by an up-pull method. According to the peeling process using the up-pull method, the carcass is transported by the transport device such as a mobile crane from the upstream side to the downstream side in the transport direction in an upside-down suspension state. The transported carcass is gradually peeled from the lower side of the carcass to the upper side while the epidermis is wound up while being pulled upward by a winding device arranged above the carcass. It is.

[0003] However, in the peeling treatment of the up-pull method, the epidermis peeled off from the carcass is taken up above the carcass by a winding device, so that bacteria and the like adhering to the epidermis are scattered above the carcass. , Will adhere to the surface of the carcass (carcass) from which the epidermis has been removed. Therefore, the peeling treatment using the up-pull method is unsanitary because carcasses may be infected with bacteria and the like.

[0004] Therefore, there has been proposed a peeling treatment by a down-pull method in which the epidermis is peeled from the upper side to the lower side of the carcass suspended in the air. According to the peeling process by the down-pull method, the carcass is transported by a transporting device such as a mobile crane from the upstream side in the transport direction to the downstream side in an upright suspension state. The conveyed carcass is gradually peeled from the upper side of the carcass to the lower side while the epidermis is pulled down by the winding device arranged below and wound up while being pulled down. It is. Therefore, it is possible to prevent bacteria and the like adhering to the epidermis from scattering and adhering to the carcass surface, thereby preventing the carcass from being infected with the bacteria and the like.

[0005] In the peeling treatment by the down-pull method, carcasses such as cows are transported in a state of being suspended upside down, and the height of the carcasses from the floor is about 3 m. For this reason, the peeling work on the upper part of the carcass is performed by a worker placed on a worktable or the like, but since such a worktable does not hold multiple workers at the same time, it is necessary to increase the speed of peeling processing. The number of workers could not be increased, and there was a limit in improving the speed of peeling.

On the other hand, a peeling apparatus capable of performing peeling without using the above-mentioned work table has been proposed. In this peeling apparatus, the carcass is placed on the floor surface, placed on a conveyor belt in a state of lying on its back, and transported downstream in the transport direction by the conveyor belt. Workers are arranged on both sides of the conveyor belt, and peel the skin in the order of the abdomen, side flanks, and back of the carcass conveyed by the conveyor belt. According to the peeling apparatus, the carcass is placed on its back and transported by the conveyor belt, so that the operator can perform the peeling operation at a lower position than the carcass suspended upside down. Therefore, when it is not necessary to use a work table when the carcass peeling operation is performed, and it is desired to increase the speed of the peeling processing, the speed of the peeling processing is improved by increasing the number of workers.

That is, tension is applied to the epidermis on one side of the carcass (left side in FIG. 5) in the direction of arrow C by one side roller 11, and the other side is applied to the epidermis on the other side of the carcass (right side in FIG. 5). The roller 11 applies tension in the direction of arrow D. Therefore, the worker can reliably apply tension to the skin without forcibly grasping the slippery skin to which oil or the like has adhered.

In such a state, when the cutting edge of a tool such as a knife is inserted into the boundary between the epidermis and the fascia of the carcass by the operator, the epidermis is easily peeled off from the abdomen of the carcass while the carcass is removed. The skin is peeled off with a smooth surface. As a result, the meat pieces are prevented from adhering to the epidermis peeled off from the carcass, and the carcass surface can be prevented from having irregularities. Therefore, it is possible to prevent the intrusion of air into the uneven portion and the freshness of the carcass from being reduced.

The carcass from which the skin of the abdomen has been peeled as described above is transported upward by the conveyor belt 4 to the downstream side, so that the skin is gradually peeled in the order of the abdomen, side flanks, and back. In addition, the peeled skin is rotated by the rotation of the pair of side rollers 11, 11, and the protrusions 11c, 1
By 1c, since it is guided toward the downstream side in the transport direction of the conveyor belt 4 in synchronization with the transport speed of the conveyor belt 4, wrinkling is prevented at the joint between the skin and the carcass. Therefore, the operator can smoothly pierce the cutting edge of a tool such as a knife into the boundary between the epidermis and the fascia, and can peel off the epidermis without forming irregularities on the surface of the carcass.

The carcass carried by the carcass carrier 2 is
The conveyor belt 4 supported while being raised and inclined by the support table 8 raises the mounting position as the sheet is conveyed to the downstream side. That is, as shown in FIG. 6, the carcass conveyed to the downstream side of the continuous peeling device 1 has its back portion near the same height as the pair of side rollers 11, 11.
The mounting position is raised. In this state, when workers on both sides of the continuous peeling apparatus 1 press the epidermis toward the side rollers 11 with one hand and press the epidermis, tension is applied to the epidermis on both sides of the carcass in the rotation direction of the pair of side rollers 11, 11. Are respectively given. That is, tension is applied to the epidermis on one side of the carcass (left side in FIG. 6) in the direction of arrow C by one side roller 11, and the other side is applied to the epidermis on the other side of the carcass (right side in FIG. 6). The roller 11 applies tension in the direction of arrow D.

In such a state, when an operator inserts the edge of a tool such as a knife into the boundary between the epidermis and the fascia of the carcass, the epidermis is easily peeled off from the back of the carcass while the carcass is peeled off. The skin is peeled off with a smooth surface. Thereafter, when the carcass reaches the upstream side of the continuous peeling device 1, the carcass is in a state where the skin of the other portions is completely peeled off, except for the contact portion of the conveyor belt 4 with the mounting plate 4a. Become.

In this state, the carcass is then lifted by a crane (not shown) or the like, and its skin is placed on the horizontal roller 10. The skin placed on the horizontal roller 10 is pressed by the worker on the upstream side of the continuous peeling device 1 toward the horizontal roller 10, and is directed in the rotation direction of the horizontal roller 10 (the direction of arrow B in FIG. 1). Tension is applied. Therefore, the worker can reliably apply tension to the skin without forcibly gripping the slippery skin to which oil or the like has adhered and which is difficult to grasp.

An operator easily inserts a cutting edge of a tool such as a knife into a boundary portion between the epidermis and the fascia to which tension is applied by the horizontal roller 10 so that the carcass (carcass) surface is smooth. As it is, the epidermis is easily peeled off. afterwards,
When the carcass is further lifted by the crane, the entire skin of the part of the carcass that is in contact with the mounting plate 4a of the conveyor belt 4 is peeled off, and the peeling process (operation) for peeling the skin from the carcass is completed.

As described above, according to the continuous peeling apparatus 1 of this embodiment, the conveyor belt 4 for transporting carcasses such as slaughtered cows is moved from the upstream side in the transport direction to the downstream side by the support 8. The supporting position of the carcass can be gradually raised as the carcass is conveyed in the conveying direction by the drive motor 5. For this reason,
When the skin is peeled from the carcass in the supine state in the order of the abdomen, the flanks, and the back, the working height of the worker can be kept constant. Therefore, when peeling the skin of the back of the carcass, the worker can work without bending down, and the work efficiency can be improved.

Moreover, since the carcass is placed on the mounting plate 4a of the conveyor belt 4 in a state of lying on the back, the carcass is hung upside down in the air and the outer skin is peeled off, compared with the conventional peeling treatment such as a down pull method. Worker's working height can be reduced. This eliminates the need for the peeling operator to be put on the worktable and perform the peeling operation as in the related art. For example, a plurality of workers can be arranged on both sides of the continuous peeling apparatus 1. For this reason, since the peeling operation of the carcass can be performed by a plurality of workers, the working speed can be improved as compared with the conventional peeling process.

As described above, the present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. It can be easily inferred.

For example, in the present embodiment, the outer peripheral surfaces of the pair of side rollers 11, 11 are spirally projecting portions 11c, 11c.
Was formed. However, the shape of the projection formed on the pair of side rollers is not necessarily limited to this, and any configuration may be used as long as the epidermis can be guided downstream in synchronization with the transport movement of the carcass.

Further, in the present embodiment, the support 8 of the carcass transfer device 2 and the supports 13 and 14 of the peeling roller device 3 are installed on a substantially horizontal floor surface. The floor surface to be installed is not necessarily limited to this. For example, the support bases 8, 13, and 14 may be installed on a floor surface that is inclined downward from the upstream side in the transport direction to the downstream side. As described above, the support bases 8, 1 are placed on the floor surface that is inclined downward.
In the case where the conveyor belts 3 and 14 are installed, the conveyor belt 4 is disposed so as to be relatively inclined upward with respect to such a downwardly inclined floor surface, while being substantially horizontal with respect to the substantially horizontal floor surface. It is arranged in a state.

For this reason, the conveyor belt 4 can convey and move the heavy carcasses such as cows relatively substantially horizontally. Therefore, in such a case, the driving force required to convey the carcass by the conveyor belt 4 is reduced, so that the drive motor 5 for driving the conveyor belt 4 is downsized to manufacture the carcass conveyance device 2. Cost can be reduced. In addition, in such a case, the worker can perform the peeling operation by standing on the floor inclined downward, so that the work height at which the worker performs the peeling operation can be maintained substantially constant. .

Hereinafter, modifications of the present invention will be described. In the peeling treatment apparatus according to claim 2, the pair of peeling rollers,
Peeling characterized in that it is arranged in a substantially horizontal state above both sides of the conveyor belt, and the interval width is arranged at substantially equal intervals from the upstream side to the downstream side in the conveying direction of the conveyor belt.

According to the peeling apparatus according to the first aspect, the transport belt on which the animal body such as the slaughtered cows is placed is inclined upward from the upstream side in the transport direction to the downstream side by the support table. The moving height of the moving object can be gradually increased as the moving object is conveyed in the conveying direction by the belt driving device. Therefore, when the skin is peeled in the order of the abdomen, the flanks, and the back from the body in the supine state, the working height of the worker can be kept constant. Therefore, when the skin of the back of the moving object is peeled off, the worker can work without bending down, so that there is an effect that the work efficiency can be improved.

On the other hand, since the moving object placed on the transport belt is placed on its back on the transport belt, the moving object is suspended upside down in the air and the skin is peeled off. Work height can be reduced. Therefore, it is not necessary for the operator who performs peeling to be placed on the work table and perform the peeling operation as in the related art, so that a plurality of workers can be arranged. That is, since the peeling work of the moving object can be performed by a plurality of workers, the working speed can be increased and the working efficiency can be improved.

According to the peeling apparatus of the second aspect, in addition to the effect of the peeling apparatus of the first aspect, in addition to the pair of peeling rollers, the outer peripheral surface of the pair of peeling rollers is located on the side of the conveyor belt provided by the roller driving device. Are rotated in the opposite directions to each other, so that the operator can press down on the skin placed on the pair of peeling rollers to apply tension to the skin and pull the skin from the moving object. Therefore,
There is an effect that tension can be easily applied to the skin without the oil being attached and the worker easily grasping the slippery skin.

Further, since the skin is pulled by the pair of peeling rollers, the edge of a tool such as a knife can easily enter the boundary between the skin and the fascia.
The epidermis can be easily peeled from the animal body. Accordingly, unlike the peeling treatment by the conventional down-pull method, there is an effect that meat pieces do not adhere to the peeled epidermis and the surface of the peeled animal body can be finished smoothly.
For this reason, the flesh is peeled off together with the epidermis, so that irregularities are formed on the surface of the moving object, and it is possible to prevent the freshness of the moving object from being reduced due to the invasion of air or the like into the irregularities.

According to the peeling apparatus according to the third aspect, in addition to the effect of the peeling apparatus according to the second aspect, the protrusion projecting from the outer peripheral surface of the pair of peeling rollers is located upstream of the pair of peeling rollers. From the part to the downstream side part, it is formed in a spiral shape in substantially the same direction as the rotation direction of the pair of peeling rollers, so that the skin pressed down by the operator toward the peeling rollers is rotated by the pair of peeling rollers. Accordingly, it can be guided in the transport direction of the transport belt. Therefore, it is possible to prevent wrinkles from forming at the joint between the epidermis peeled from the animal and the animal, and easily insert the cutting edge of a working tool such as a knife into the boundary between the epidermis and the fascia. . Therefore,
There is an effect that meat pieces do not adhere to the peeled epidermis and the peeled animal body surface can be finished smoothly. For this reason, the flesh is peeled off together with the epidermis, so that irregularities are formed on the surface of the moving object, and it is possible to prevent the freshness of the moving object from being reduced due to the invasion of air or the like into the irregularities.
