Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a peeling apparatus, and more particularly to a peeling apparatus for peeling foods with skins widely, such as skins of wiener sausages and sausages, and skins of cheese with skins packed with cheese. It relates to a peeling device.

[0002]

2. Description of the Related Art In the case of skinned foods, for example, skinned wiener sausages, a variety of skins or casings such as sheep intestine are usually placed in a length of 4 to 5 cm (recently 2 cm in length). ), The raw material consisting of meat, etc., starch and other auxiliary materials as needed, seasonings and spices are packed, and the skin is twisted several times. Is manufactured. On the other hand, in recent years, it has become necessary to produce a skinless wiener sausage or the like due to consumer's preference. An operation for peeling sausage is required, and there has been a demand for a peeling apparatus for skinned food.

In this connection, a continuous skinned food product, for example a continuous wiener sausage, which has not yet been individually separated, is transported in its longitudinal direction and is arranged downstream of the transported wiener sausage. The top of the wiener sausage skin is torn by the cutter along the length of each wiener sausage, and further arranged downstream, in the transport direction, transversely to the longitudinal direction of the wiener sausage, side by side, and slightly spaced apart A pair of rollers, and a suction device disposed below these rollers are installed, and only the skin whose top is torn is pulled between the rollers by rotating the rollers inward, that is, , Peel the skin from the Wiener sausage, remove the skin, and remove the peeled skin in place by a suction device, Peeling device is known to say.

[0004]

However, since the pair of rollers has to pull the cleaved skin between the rollers, the gap or interval between the rollers is determined by the thickness of the skin of the food to be drawn. Where they must be approximately equal, the skin connecting adjacent foods is twisted, so the skin thickness between adjacent foods is greater than the skin thickness of the individual foods. Therefore, when the twisted skin is conveyed between the rollers having a distance corresponding to the thickness of the skin of the individual food, the twisted skin is moved between the rollers. May be jammed. In this case, not only must the work be interrupted, but also the clogged skin must be removed from the device, which inevitably reduces the work efficiency.

Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide an apparatus for peeling a skin having an irregular thickness.

[0006]

In order to achieve the above object, a peeling apparatus according to the present invention comprises a transporting means for transporting a food with skin, and the peeling apparatus arranged downstream of the transporting means. Cutter means for tearing the peeled food, a pair of peeling rollers arranged downstream of the transport means for peeling the torn peel from the food, and the pair of peeling rollers with respect to each other. A driving unit for rotating the pair of peeling rollers inward, a roller supporting unit for rotatably supporting at least one of the pair of peeling rollers in a direction away from the other roller, and the pair of peeling rollers. Roller urging means for urging in the direction to cause the pair of skin peeling rollers to roll the skin of the food between the pair of skin peeling rollers, whereby the pair of skin peeling rollers reduce the urging force of the roller urging means. Outside to resist Even when displaced, and having a rotational force transmitting means for rotating said pair of peeling rollers.

In the present invention, it is preferable to have a collecting means disposed under the pair of peeling rollers for sucking and collecting the skin peeled off by the pair of peeling rollers. Further, in the present invention, it is preferable to have a pressurized air supply means disposed above the pair of peeling rollers for enlarging a cut formed in the skin of the food by the cutter means. Furthermore, it is preferable that the apparatus further includes a second transport unit for transporting the food whose skin has been peeled off by the pair of peeling rollers to a next station located downstream of the pair of peeling rollers.

[0008]

According to the peeling apparatus having the above construction, the transporting means transports the food with skin to the cutter means, and the cutter means tears the crest of the food, and the lower part of the cleaved skin is used as a pair of skins. The peeling roller gets caught or entangled in between. Then
At least one of the pair of peeling rollers is displaced outward against the urging force of the urging means by the skin sandwiched therebetween, and a gap is generated between the pair of peeling rollers. Even when the pair of peeling rollers (at least one of them) is displaced outward, the rotational force transmitting means for rotating the pair of peeling rollers continues to rotate the pair of peeling rollers. The peeled skin is pushed downward by the rotation of the roller from the gap between the pair of peeling rollers, and when the collecting means is provided, the collecting means sucks and collects the skin.

[0009] A skinned food in a continuous state is used in the present apparatus, and a twisted skin between adjacent skinned foods that is thicker than the skin covering the food is conveyed to a pair of skinning rollers. Even if it has been done, the pair of peeling rollers are displaced outward by a distance corresponding to the thickness of the twisted leather, and the peeling roller is rotated even during such outward displacement of the peeling roller. Subsequently, the twisted thick skin is continuously pushed downward, so that the skin does not clog the pair of peeling rollers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In this embodiment, the present invention is applied to an apparatus for peeling a skinned food (hereinafter, referred to as “winner” for convenience) such as a skinned wiener sausage and a skinned cheese. FIG.
As shown in FIG. 1, the peeling apparatus 1 has a sprocket 2 driven by a motor (not shown) and a floating sprocket 3, and a chain 4 is wound around these sprockets. A plurality of support members 5 for transporting skinned food are attached to the outer peripheral surface of the chain 4, and each support member 5 has a recess 6 at the center in the width direction as can be clearly seen in FIG. 4. 6, the wiener can be stably supported and transported.

Above the upper straight portion of the chain 4, a plurality of guide rollers 7 are linearly installed facing the chain. Therefore, the wiener W to be processed is transported by the support member 5 of the chain 4 while the upper portion is guided and supported by the rollers 7. A cutter 8 is arranged at a downstream end portion of the linearly arranged guide roller 7,
The cutting edge of the cutter 8 projects downward from the lower surface of the outer periphery of the guide roller 7 and tears the top of the skin of the wiener conveyed by the support member 5 without damaging the wiener body. Downstream of the most downstream guide roller 7A, which has a rotation axis in the same vertical plane as the rotation axis of the sprocket 3, several guide rollers 9 are located almost upstream of the sprocket 2 ("left side" when viewed in FIG. 1). It is arranged along the arc part. Downstream of the most downstream guide roller 9A, a first chute 10 is installed adjacent to the guide roller 9A and the support member 5 of the sprocket 2. First shot 1
Reference numeral 0 denotes a guide member having a U-shaped cross section, which is constituted by left and right side walls 10A and 10B and a bottom wall 10C connecting these side walls, and is inclined downward in the downstream direction.

A pressurized air jet nozzle 11 is provided above the downstream end of the first chute 10, and this nozzle 11 is connected to a pressurized air source (not shown). This nozzle 11
By blowing out pressurized air from, the cuts in the skin of the wiener torn by the cutter 8 can be widened, thereby facilitating the peeling described later.
In order to accurately tear the top of the skin of the wiener in the longitudinal direction and not to damage the wiener body, the cutter 8 is provided in a place where the wiener W is in a straight state, that is, the upper straight line of the chain 4. When the sprocket has an enlarged diameter, the place where the cutter 8 is installed is separated from the place where the pressurized air jet nozzle 11 is installed. After the cut is made, before the nozzle 11 is reached, the wiener W swings and the cut in the skin is displaced from the top of the wiener.
It may not be possible to widen the cut in the skin formed by the pressurized air from one. In this regard, in the present embodiment, the area where the chain 4 is curved is reduced by using the small-diameter sprocket 2, and the distance between the cutter 8 and the nozzle 11 arranged before and after this curved area is shortened. The above-described problem caused by the swing of the wiener is solved.

Downstream of the first chute 10, the upstream end is located below the downstream end of the first chute 10.
A pair of peeling rollers 20, 21 are provided. The pair of peeling rollers 20 and 21 have respective rotation axes substantially parallel to the longitudinal axis of the continuous wiener W, and the contact line formed by the contact between the peeling rollers 20 and 21 is the first chute. The center of the support member 5 in the width direction is substantially aligned with the center of the support member 5 in the width direction. Also, knurls are formed on each of the rollers 20 and 21 to make it easier to peel the skin of the wiener. The peeling rollers 20, 21 are provided with shafts 22, 2 projecting downstream.
3 and these shafts 22 and 23 are respectively
It is rotatably supported by bearings 24 and 25. The outer diameters of the shafts 22 and 23 and the bearings 24 and 25 are smaller than the outer diameters of the rollers 20 and 21 because a second chute described later is arranged above these. The bearing 24 of the shaft 22 is fixedly supported on the frame of the device 1 via a bracket 26, as can be clearly seen in FIG. A bracket 27 is also attached to the bearing 25 of the shaft 23, and the bracket 27 is used to move the roller 21 away from the roller 20 in a direction perpendicular to the rotation axis of the roller 20. To be rotatable. A spring 27 </ b> A is provided between the brackets 26 and 27 so as to constantly bias the bracket 27 toward the bracket 26, and thus to keep the roller 21 in contact with the roller 20.

As can be clearly seen in FIG. 2, the peeling roller 20 has a connecting rod 28 projecting downstream from the shaft 22. This connecting rod 28 comprises a gear or a toothed ring 29 and is rotatably supported by a support wall 30 downstream of the ring 29. Support wall 30
Pulley 31 is attached to the downstream end of connecting rod 28 that
The pulley 31 is connected to a pulley 3 connected to a motor M via a gear train (not shown) in a gear box G.
2 and a belt B. Peeling roller 21
Has a connecting rod 33 extending downstream from the shaft 23. The connecting rod 33 includes a proximal rod 33A connected to the shaft 23 and a distal rod 33B.
And a rotational force transmitting member 33C for connecting them. The distal rod 33B includes a gear or a toothed ring 34 that engages the toothed ring 29 of the connecting rod 28 of the roller 20 and is rotatably supported by the support wall 30 downstream of the ring 34. Accordingly, the driving force from the motor M is transmitted to the ring 34 via the ring 29, and the roller 21 is idled via the connecting rod 33.

As best seen in FIG. 3, the proximal rod 3
3A comprises on its distal end face a projection 35 of rectangular cross section extending straight from the opposite edge of the distal end face through the axis of rotation of the rod 33A, i.e. extending diametrically; The distal rod 33B has a protrusion on its proximal end surface that extends straight through the axis of rotation of the rod from opposite edges of the distal end surface, i.e., a rectangular cross-section that extends diametrically. 36. The rotational force transmitting member 33C can slide the protruding portion 35 of the proximal rod 33A at the proximal end facing the proximal rod 33A, that is, in this embodiment, the protruding portion 35
And a recess 37 formed complementary to the distal rod 3.
At the distal end facing 3B, the protrusion 36 of the distal rod 33B is slidable, ie in this embodiment comprises a recess 38 formed complementary to the protrusion 36, The recesses 37, 38 are positioned so as to be orthogonal to each other. The rotational force transmitting member 33C is disposed between the proximal rod 33A and the distal rod 33B such that the recess 37 receives the protrusion 35 and the recess 38 receives the protrusion 36.

According to the rotational force transmitting member 33C, when the roller 21 is moved in a substantially horizontal direction so as to move away from the roller 20, for example, as shown in FIG. Part 35 and rotational force transmitting member 33
If both recesses 37 of C are horizontal, the substantially horizontal force exerted on roller 21
Since the protrusion 35 of A slides on the concave portion 37 of the torque transmitting member 33C and is displaced, it does not act on the torque transmitting member 33C, so that the torque transmitting member 33C moves substantially horizontally. That is, it is not driven or displaced by the displacing roller 21 and the proximal rod 33A fixed thereto. On the other hand, the driving force from the motor M is continuously transmitted to the rotational force transmitting member 33C via the distal rod 33B, the ring 34, and the like. When the (displaced) engagement with the protruding portion 35 of the proximal rod 33A in the displaced state, the proximal rod 33A and, consequently, the roller 21 are rotated even during the displacement.

Next, the roller 21 and the proximal rod 33
When the rotational force transmitting member 33C continues to rotate during the displacement of A and the concave portion 37 changes from horizontal to vertical, the horizontal force by the protruding portion 35 of the proximal rod 33A is reduced by the concave portion 3A.
7 to the torque transmitting member 33C,
The rotational force transmitting member 33C is entrained by the proximal rod 33A and is displaced away from the connecting rod 28 of the roller 20. However, when the concave portion 37 of the rotational force transmitting member 33C changes from horizontal to vertical, the concave portion 38 and the protruding portion 36 of the distal rod 33B are both horizontal, and the horizontal force applied to the rotational force transmitting member 33C. Is the distal rod 3
Since it does not act on 3B, the distal rod 33B is not entrained or displaced by the rotational force transmitting member 33C. On the other hand, since the driving force from the motor M is continuously transmitted to the distal rod 33B via the ring 34 or the like, the rotation of the distal rod 33B causes the protrusion 36 to be displaced. When (offset) engagement with the concave portion 38 of a certain rotational force transmitting member 33C is performed, the rotational force transmitting member 33C, and consequently, the proximal rod 33A and the roller 21 are rotated even during displacement.

The relationship between the rotational force transmitting member 33C and the proximal rod 33A and the distal rod 33B is described above.
In order to facilitate understanding, the concave portion 3 of the rotational force transmitting member 33C is used.
Although the description has been made only in the transitional state in which the horizontal and vertical positions 7 and 38 are provided, in actuality, the rotational force transmitting member 33C
It will be understood that the movements of the protrusions 35, 36 of the proximal rod 33A and the distal rod 33B in the recesses 37, 38 of the two rods occur simultaneously and in combination. As shown in FIGS. 1 and 2, a suction device 40 for sucking and collecting the wiener skin peeled off by these rollers is arranged below the rollers 20 and 21. The suction device 40 is a roller 2
The suction tube 41 has an open end 41A facing the lower surface of the collecting container 42 and an open end 41B connected to the collection container 42. The collection container 42 is connected to the pump P,
A mesh member (not shown) is attached to the inside adjacent to the connection portion with. Therefore, the skin of the wiener peeled off by the rollers 20 and 21 is sucked into the collection container 42 via the suction pipe 41 by the suction force of the pump P and is caught by the mesh member, that is, collected in the collection container 42. .

A second chute (not shown) inclined downward in the downstream direction for transporting the peeled wiener to a station for the next process is provided with bearings 24, 2 and 3.
5, located above the connecting rods 28, 33, the rings 29, 34 and the support wall 30 and extending between the downstream end of the rollers 20, 21 and the next station. Next, the operation of the above embodiment will be described. Wiener with continuous skin W
Is inserted from the upstream side between the support member 5 and the guide roller 7 in the upper straight portion of the chain 4, the wiener W
Are transported downstream by the drive of the chain 4 while being connected to each other, and the top of the skin is sequentially torn by the cutter 8. The wiener W whose top is torn is then guided into the first chute 10 by the guide member 9 and the support member 5 on the sprocket. At the lower end of the first chute, the cut made by the cutter 8 is enlarged at the lower end of the first chute by the pressurized air jetted from the pressurized air jet nozzle 11, particularly in the width direction.

The wiener having an enlarged cut is then moved from the first chute 10 onto rollers 20 and 21 provided with knurls. Next, the lower part of the skin is sandwiched between the rollers 20 and 21 by the rollers 20 and 21 that are rotated inward toward each other, and the skin is particularly enlarged from the lower part by the rollers 2 and 21.
The peeled skin is peeled downward by 0, 21 and the peeled skin is pressed against the roller 2 against the biasing force of the spring 27A.
The roller 21 is moved or displaced away from 0, and is pushed downward from a gap formed between the rollers 20 and 21. Even during such displacement of the roller 21, the roller 21 is displaced in the manner described above. Keeps rotating. The skin extruded from between the rollers 20 and 21 is collected in the collection container 42 by the suction device 40.

Following the skin covering the surface of the wiener, a twisted skin T located between adjacent wieners,
Therefore, the skin T thicker than the skin on the surface of the wiener is
When sandwiched between 0 and 21, this thick skin T
The roller 21 is displaced farther away from the roller 20 than when the skin on the wiener surface is sandwiched between the rollers 20 and 21 against the urging force of 7A. , The roller 21 continues to rotate during the displacement, and continues to supply the skin to the suction device 40 in cooperation with the roller 20. The stripped wiener slides down the second chute (not shown) from the rollers 20 and 21 and is conveyed to the next station. The present invention
The following various changes are possible without being limited to the above-described embodiment.

For example, in the above embodiment, the rod 33
Although the projections 35 and 36 of A and 33B have a rectangular cross-sectional shape, the projections 35 and 36
It is sufficient that the inside of the recesses 37 and 38 of the 3C can be slid, and for example, a semicircular cross section may be used. In the above-described embodiment, the projecting portions 35 of the rods 33A and 33B,
36 is an end face of the rod 33A, 33B,
Although the concave portions 37 and 38 of the rotational force transmitting member 33C extend diametrically at the ends of the member 33C, respectively, the projecting portions 35 and 36 pass through the rotation axes of the rods 33A and 33B, but the rods 33A and 33B. 33B is formed so as not to extend from the edge to the edge of the rotation force transmitting member 33C.
The outer edges of the concave portions 37 and 38 may be closed. With this configuration, it is possible to prevent the torque transmitting member 33C from falling off the rods 33A and 33B.

Further, in the above embodiment, the roller 2
When the skin is taken in between 0 and 21, the roller 21 is continuously rotated while displacing the roller 21 with respect to the roller 20, so that the rotation force transmitting member 33C is employed, but the displacement of the roller 21 is allowed. However, another structure that can continue to rotate the roller 21 may be adopted. For example, a connecting rod is extended downstream from the roller 21 and the connecting rod is appropriately rotatably supported by a support, and the downstream end of the connecting rod is connected to a fixed motor via a flexible tube, and The support may be rotatably mounted on the apparatus frame so that the roller 21 can be moved away from the roller 20. Further, the motor and the connecting rod may be integrally connected by a rigid shaft, and the motor together with the support may be integrally rotatable.

Further, in the above-described embodiment, the peeling apparatus 1 is configured so that only the roller 21 can be moved or displaced with respect to the roller 20. However, the peeling apparatus 1 can be continuously rotated during operation of the apparatus. If possible, rollers 20, 21
May be configured to be able to move or displace with respect to each other. For example, for each roller, as described immediately above, a connecting rod extends downstream from the roller, and the connecting rod is appropriately rotatably supported by a support, and the downstream end of the connecting rod is a flexible tube. Connected to a fixed motor via a motor, and the support is rotatably mounted on an apparatus frame so that the support can be moved away from the other roller. The motor may be integrally connected by a rigid shaft, and the motor may be integrally rotatable together with the support.

Further, in the above embodiment, the roller 2
Although knurls were formed on 0 and 21, rollers 20 and 21 were rollers 20 and 2 other than knurls.
Means for improving the engaging force between the skin 1 and the skin can be provided. For example, the roller surface may be made of a material such as rubber having a high coefficient of friction.
