Description

The present invention automatically peels the skinned contents in a state where the contents are wrapped in the outer skin to separate the outer skin from the contents, in other words, automatically peels the outer skin and removes the contents. The present invention relates to an automatic peeling machine that can be taken out.
In addition, as a thing with a skin in which the contents are wrapped with an outer skin, for example, edamame, peas, peanuts and the like can be assumed. In this case, the content refers to “beans” and the hull refers to “beans” and “shells”.
In this case, in the technical field of the automatic molting device of the present invention, in particular, in the case of a boiled skinned product (for example, green soybeans, peas, peanuts, etc.) or a thawed skinned product, the skin is automatically peeled off The case where an object is taken out is also included in the assumed range.

  Conventionally, various techniques for peeling the outer skin of a skin-attached object are known. As an example, the technique disclosed in Patent Document 1 (invention name “bean peeling machine”) peels an immersed bean, and includes a pair of relatively long and large-diameter rollers and a pair of these. Extending between the rollers, and having a sloped slope from one end to the other end between the rollers, and the peeled beans from one end between the pair of rollers And a screw to be dropped on the inclined surface.

  In such a bean peeling machine, the peeled beans that have fallen onto the table (on the inclined surface) from one end side between the pair of rollers are continuously aligned one by one along the inclined surface. When the pair of rollers is rotated, a force pulling the side of the peeled beans downwards acts, so that only the outer skin is peeled off and discharged, and the beans that are the contents are Sent along and collected.

JP 2011-50260 A

  By the way, in the conventional bean peeling machine, the main structure is only a pair of rollers, and only the peeled beans that are fed with the table (inclined surface) aligned between the pair of rollers are peeled off. Is done. For this reason, there is a certain limit to the number of peeled beans that can be peeled at a time. The time required for processing is prolonged. In short, there is a certain limit to performing a large amount of molting at once in a short time.

  In this case, if the rotational speed of the pair of rollers is increased, it can be expected that the number of peeled beans to be peeled will be increased or the time required for the peeling will be shortened. However, depending on the degree of rotation speed of each roller, it becomes difficult not only to peel the outer shell from the peeled beans without damaging the contents, but also the power consumption required for high-speed rotation increases. As a result, it goes against energy conservation.

  The present invention has been made to solve such a problem, and its purpose is to promote energy saving while ensuring a large amount of molting treatment at a time in a short time without damaging the contents. An object of the present invention is to provide an automatic molting device that can be performed.

In order to achieve such an object, the present invention is an automatic molting device that automatically performs a molting treatment on a skinned item in a state where the contents are wrapped in an outer skin, and separates the outer skin from the contents, A hollow cylindrical rotating structure configured to be rotatable about one rotating shaft, and detachably provided at predetermined intervals along the circumferential direction around the rotating shaft with respect to the rotating structure. A plurality of molting shafts that revolve around the rotation axis following the rotational movement and rotate at the same time, and the molting shafts that are adjacent to each other in the circumferential direction have only a skinned skin between them. A plurality of peeling shafts are configured to have a gap that does not allow the contents to pass while passing, and are configured to rotate in opposite directions, and follow the rotational movement of the rotating structure. Around the axis of rotation At the same time, by rotating adjacent molting shafts in opposite directions to each other, a plurality of skinned objects positioned between adjacent molting shafts in a plurality of locations along the circumferential direction are used for the molting. While being peeled and removed by being pulled through the gap between the shafts, the contents are recovered by remaining on the gap between the peeling shafts.
In the present invention, each of the plurality of molting shafts is provided so as to be relatively displaceable with respect to the rotating structure, and the respective molting shafts are relatively displaced during the rotation of the rotating structure. The gap between the peeling shafts adjacent to each other in the circumferential direction is changed.
In the present invention, the rotating structure rotates around the rotation axis, and is configured separately from the rotating portion to which a plurality of molting shafts can be attached, and the rotating portion. The non-rotating portion is provided with a continuous gear mechanism around the rotation axis along the circumferential direction, and a plurality of molting shafts attached to the rotating portion are adjacent to each other. Are meshed with each other and every other gear mechanism in the circumferential direction meshes with the gear mechanism of the non-rotating part, and when the rotating part is rotated, each meshed with the gear mechanism follows this. The molting shaft rotates while revolving, and the rotational force at this time is transmitted to adjacent molting shafts that mesh with each other, so that all the molting shafts rotate with equal rotational force. To do.
In the present invention, the rotating shaft of the rotating structure is inclined downwardly from the input side where a plurality of skinned items can be simultaneously input, toward the discharge side of the contents that have undergone molting treatment, Each of the plurality of molting shafts extends in parallel along the same direction as the rotating shaft inclined in a descending gradient, and concentrically around the rotating shaft at predetermined intervals along the circumferential direction. A plurality of items with skin that are input from the input side are peeled off by the respective peeling shafts and separated into the outer skin and the contents, while the contents are discharged and recovered from the discharge side Is done.
In the present invention, on the discharge side of the contents that have been subjected to the molting process, the plurality of molting shafts each have an outer diameter smaller than that of the other part, thereby providing a gap between the molting shafts. The contents that have spread and have been peeled off and separated from the outer skin are discharged and collected from the widened gap between the respective peeling shafts on the discharge side.

  According to the present invention, it is possible to realize an automatic molting apparatus that can safely and reliably perform a large amount of molting treatment at a time without damaging the contents while promoting energy saving. .

The perspective view which expands and shows a structure partially.

Hereinafter, an automatic peeling machine according to an embodiment of the present invention will be described.
The automatic peeling machine of the present embodiment automatically peels the skinned material in which the contents are wrapped in the outer skin to separate the outer skin from the contents, in other words, automatically removes the outer skin. It is possible to peel off and take out the contents. In addition, in this embodiment, as a thing with a skin in which the contents are wrapped in an outer skin, for example, green soybeans, peas, peanuts, and the like can be assumed. In this case, the content refers to “beans” and the hull refers to “beans” and “shells”.

  As shown in FIGS. 1 (a), 1 (b) and 2, the automatic molting device of the present embodiment includes a hollow cylindrical rotating structure 4 configured to be rotatable around one rotating shaft 2, The rotary structure 4 is detachably provided at predetermined intervals (for example, at equal intervals) around the rotary shaft 2 around the rotary shaft 4, and revolves around the rotary shaft 2 following the rotary motion of the rotary structure 4. A plurality of molting shafts 6 that rotate at the same time are provided.

  Here, the rotary shaft 2 of the rotary structure 4 extends from the input side P1 where a plurality of skins (not shown) can be input simultaneously to the discharge side P2 of the contents that have been subjected to the molting process in the automatic peeling machine. I'm out. In this case, each of the plurality of molting shafts 6 extends in parallel with the rotation shaft 2 and is arranged concentrically around the rotation shaft 2. Note that the number, thickness (diameter), length, etc. of the molting shaft 6 are set according to, for example, the purpose and environment of use of the automatic molting device, or the type of the item with skin. There is no particular limitation.

  The rotating structure 4 rotates around the rotating shaft 2 and is configured separately from the rotating parts 4a and 4b to which a plurality of molting shafts 6 can be attached, and the rotating parts 4a and 4b, and is always in a non-rotating state. A non-rotating portion 4c (see FIG. 3) that is maintained is provided, and the non-rotating portion 4c is provided with a gear mechanism 8 (described later) that is continuous around the rotating shaft 2 along the circumferential direction. . In the present embodiment, the rotating portions 4a and 4b are hollow disk-shaped input sides that are rotatably provided on the input side P1 of the skinned article so as to rotatably support both sides of each peeling shaft 6. The rotating part 4a and a hollow disk-like discharging side rotating part 4b that is rotatably provided on the discharging side P2 of the peeled contents are configured.

  Here, a plurality of rotational motion transmission mechanisms 10 are provided at predetermined intervals (for example, equal intervals) along the circumferential direction in the making-side rotation unit 4a. The base ends 6a of the molting shaft 6 are connected one by one. On the other hand, a plurality of free rotary bearing mechanisms 12 are detachably provided at predetermined intervals (for example, equal intervals) along the circumferential direction in the discharge-side rotating portion 4b. The tip of each molting shaft 6 is connected to each other in a rotation-free manner.

  In this case, the rotational motion transmission mechanism 10 includes a single shaft portion 16 that is rotatably supported by bearing mechanisms 14 provided on both sides of the insertion-side rotation portion 4a, and the peeling shaft 6 from the shaft portion 16. A connecting portion 18 protruding toward the base end 6 a is provided, and the base end 6 a of the molting shaft 6 can be connected to the connecting portion 18. According to this, by rotating the shaft portion 16 and rotating the connecting portion 18, the rotational motion of the connecting portion 18 can be transmitted to the molting shaft 6 and the molting shaft 6 can be rotated.

  In addition, as a method of connecting the rotational motion transmission mechanism 10 (connecting portion 18) and the base end 6a of the peeling shaft 6 to each other, for example, existing connecting methods such as fitting, press-fitting, adhesion, and screwing are applied. However, here, as an example, the connecting portion 18 has a chamfered hexagonal column shape, and along the six side surfaces, every other key groove 18g is formed. The base end 6a is formed in a hollow cylindrical shape, and one key (not shown) is projected along the inner peripheral surface. Then, by inserting the key into any one of the key grooves 18g, the rotational motion transmission mechanism 10 (connecting portion 18) and the base end 6a of the peeling shaft 6 can be connected to each other.

  In addition, in the plurality of molting shafts 6 attached to the above-described rotating units (the input-side rotating unit 4a and the discharge-side rotating unit 4b), the input-side rotating unit 4a is included in the shaft portion 16 of each rotary motion transmission mechanism 10. A drive mechanism is provided on the opposite side of the connecting portion 18 across the gap. In the present embodiment, the drive mechanism is configured concentrically around the shaft portion 16 and includes a transmission gear 20 that rotates together with the shaft portion 16 and a connection gear 22.

  As shown in FIGS. 2 and 3 (a) and 3 (b), one transmission gear 20 is provided for each of the shaft portions 16, and adjacent transmission gears 20 along the circumferential direction are It is comprised in the state which mutually meshed. In addition, one connection gear 22 is provided on each of the plurality of shaft portions 16 on the other shaft portions 16 along the circumferential direction, and each connection gear 22 is connected to the non-rotating portion 4c. The gear mechanism 8 is engaged with the gear mechanism 8. In this state, the plurality of molting shafts 6 attached to the rotating portions 4a and 4b are meshed with each other, and every other non-rotating portion 4c along the circumferential direction. The gear mechanism 8 is engaged.

  The gear mechanism 8 is continuous in the circumferential direction along the outer periphery of the non-rotating portion 4c and is fixed to the non-rotating portion 4c. In the drawing, an endless roller chain is applied as an example of the gear mechanism 8, and the roller chain is fixed continuously in the circumferential direction along the outer periphery of the non-rotating portion 4c. In this case, as a method for fixing the gear mechanism (roller chain) 8, for example, an existing method such as adhesion, screwing, or fitting can be applied. Further, a gear mechanism other than the roller chain may be applied as the gear mechanism 8.

  Further, as the connection gear 22 meshed with the gear mechanism 8, when a roller chain is applied as the gear mechanism 8, a sprocket having good meshing with the roller chain may be applied. Moreover, as the transmission gear 20, as long as adjacent ones along the circumferential direction can be satisfactorily engaged with each other, any type of transmission gear 20 may be used.

  On the other hand, as shown in FIGS. 1A, 1B, and 2, the free rotary bearing mechanism 12 rotatably supports the tip 6b of the molting shaft 6 extending beyond the discharge-side rotating portion 4b. A bearing 24 is provided, and the bearing 24 is attached to the discharge-side rotating portion 4 b via the housing 26. As the bearing 24, for example, a rolling bearing such as a ball bearing or a roller bearing, a sliding bearing without a rolling element, or the like can be applied. However, here, as an example, an inner ring 24a that is disposed so as to be relatively rotatable. Further, a ball bearing including an outer ring 24b and a plurality of rolling elements (balls) 24c incorporated so as to freely roll along the inner and outer rings is assumed. In this case, the bearing 24 is covered with a sealing plate 28 in order to prevent leakage of the lubricant sealed in the bearing 24 and entry of foreign matter (for example, dust, water, etc.) into the bearing 24. Is preferred.

  Further, in the present embodiment, in the plurality of molting shafts 6 attached to the above-described rotating parts (the input-side rotating part 4a and the discharge-side rotating part 4b), the molting shafts 6 adjacent in the circumferential direction are A gap G1 (FIG. 1 (b)) is formed so as to allow only the outer skin of the skinned material to pass but not the contents. Note that the gap G1 between the molting shafts 6 is set according to the thickness (width) of various skins and the thickness (width) of the contents after the molting treatment. Then, the numerical value is not particularly limited.

  In this case, when the rotating structure 4 (the rotating portions 4a and 4b) is rotated, the connecting gear 22 meshing with the gear mechanism 8 follows the rotating motion and rolls along the gear mechanism 8. By rotating while rotating, each of the molting shafts 6 rotates along with the connection gear 22 while revolving around the rotation axis 2. Then, the rotational force at this time is transmitted to adjacent molting shafts 6 through the transmission gears 20 meshing with each other along the circumferential direction, so that all the molting shafts 6 are equal to each other. Rotate with a rotational force of (specifically, rotate in opposite directions).

  In this state, the outer skin of the plurality of skinned articles positioned between the peeling-off shafts 6 adjacent to each other at a plurality of locations along the circumferential direction is pulled through the gap G1 between the peeling-off shafts 6. And the contents are recovered by remaining in the gap between the peeling shafts 6.

  More specifically, when rotating the rotating structure 4 (the rotating parts 4a and 4b), the rotating structure is formed in a plurality of gaps G1 formed between the molting shafts 6 that rotate in opposite directions. The gap G1 in which both the molting shafts 6 rotate from the inner side to the outer side of 4 and the gap G1 in which both the molting shafts 6 rotate from the outer side to the inner side of the rotating structure 4 are alternately arranged along the circumferential direction. Will be repeated.

  Here, as shown in FIG. 1B, when attention is paid to the four molting shafts 6, three gaps G1 are formed between the molting shafts 6, and in the central gap G1, Both molting shafts 6 rotate from the inside to the outside of the rotating structure 4, and both molting shafts 6 rotate from the outside to the inside of the rotating structure 4 in the gap G <b> 1 on both sides.

  At this time, the plurality of skinned objects positioned along the central gap G1 are peeled and removed by pulling the outer skin through the gap G1 by the two molting shafts 6 rotating from the inside to the outside. Is done. And the contents after the molting process cannot be passed through the gap G1, but are recovered by remaining on the gap G1 between the two molting shafts 6.

  In the above-described peeling process, the rotating structure 4 (rotating portions 4a and 4b) may be rotated manually or electrically. In this embodiment, the rotating structure is utilized by using the rotational force of the motor. 4 (rotating parts 4a, 4b) is rotated. For example, as shown in FIG. 1 (a) and FIGS. 3 (a) and 3 (b), a gear structure 30 (for example, a sprocket) is constructed continuously in the circumferential direction along the outer periphery of the input side rotating portion 4a. The endless belt 32 (for example, a roller chain) is passed over the gear structure 30 and the output gear 34a of the motor 34, so that the rotational movement of the output gear 34a is transmitted to the gear structure 30 via the endless belt 32. Therefore, the rotating structure 4 (the rotating portions 4a and 4b) can be rotated in a predetermined direction at a predetermined speed.

  As described above, according to the automatic peeling machine of the present embodiment, a plurality of peeling shafts 6 are arranged concentrically along the hollow cylindrical rotating structure 4, so that a large amount of skinned objects can be obtained from the input side P1. Not only can it be put in at once, but also, while revolving a plurality of molting shafts 6 and simultaneously rotating adjacent molting shafts 6 in opposite directions, it extends over a plurality of locations along the circumferential direction. It is possible to simultaneously perform the peeling process on a plurality of skinned objects positioned between the adjacent peeling shafts 6. As a result, it is possible to carry out a batch peeling process by adding a large amount of skinned items, that is, a large amount of peeling process at once.

  In this case, in particular, a large amount of molting can be performed without increasing the rotation (rotation) speed of each molting shaft 6, and therefore it is necessary to increase the rotation speed of the rotating structure 4 (rotating portions 4 a and 4 b) by the motor 34. As a result, it can be safely and securely peeled without damaging the contents, and the power consumption can be greatly reduced and energy saving can be promoted.

  In addition, since a large amount of skinned material introduced from the feeding side P1 is always stirred by the plurality of skinning shafts 6 that rotate while revolving, clogging of skinned materials between the skinning shafts 6 is clogged. It is possible to perform the molting process at the same time while preventing the occurrence of the above. Thereby, the yield in the molting process can be dramatically improved.

  Furthermore, according to the automatic peeling machine of the present embodiment, the peeling-off shafts 6 adjacent to each other in the circumferential direction are engaged with each other, so that all the peeling-off shafts 6 rotate with equal rotational force. (Specifically, they can rotate in opposite directions). As a result, it is possible to perform a moulting process without spots on each skinned object, and as a result, the skin of each skinned object can be reliably peeled off and the contents can be safely and reliably removed.

  In this case, the rotation (rotation) direction of all the molting shafts 6 can be reversed simultaneously only by reversing the rotation direction of the rotating structure 4 (rotating portions 4a, 4b). This not only removes foreign matter such as branches mixed in the raw material and returns to the initial state, but also, for example, depending on the purpose and environment of use of the automatic molting device, or the size and type of the items with skin Such reversal operation can be incorporated (programmed) into the molting process, and as a result, the efficiency, smoothness, and speeding up of the molting process according to needs can be promoted.

  In addition, this invention is not limited to above-described embodiment, For example, the following technical thoughts (1)-(3) are also included in the scope of the right of this invention.

(1) Each of the plurality of molting shafts 6 is provided so as to be relatively displaceable with respect to the rotating structure 4 (the rotating parts 4a and 4b). The rotating structure 4 (the rotating parts 4a and 4b) During the rotation, the respective peeling-off shafts 6 are relatively displaced, thereby changing the gap between the peeling-off shafts 6 adjacent to each other along the circumferential direction. In short, in the peeling process, each peeling shaft 6 is configured to be loosely moved (displaced).

  In order to realize such a configuration, in the present embodiment, as an example, a gap is provided between the tip 6b of each peeling shaft 6 and a bearing 24 that rotatably supports the tip 6b. Specifically, as shown in FIG. 2, a predetermined gap is formed between the tip 6 b of each molting shaft 6 and the inner ring 24 a of the bearing 24. In addition, since the magnitude | size of a clearance gap is arbitrarily set, for example according to the intended purpose and usage environment of an automatic peeling machine, or the magnitude | size and kind of a thing with a skin, it does not specifically limit here.

  In this technical idea (1), in the peeling process, each peeling shaft 6 is always rattled and is finely moved (displaced), and in that case, the tip 6b of each peeling shaft 6 may be worn and deteriorated at an early stage. There is also. Therefore, in order to prevent the occurrence of such a problem, for example, a collar 36 made of a synthetic resin (or a metal having wear resistance) is attached to the tip 6b of each peeling shaft 6 (for example, an interference fit). In addition, it is preferable that the tip 6b of each peeling shaft 6 and the inner ring 24a of the bearing 24 are not in direct contact with each other.

  As described above, according to the present technical idea (1), since each of the molting shafts 6 is loosely moved (displaced) during the dehulling process, the safety and certainty of the dehulling process for a large amount of peeled objects (that is, , And reliably peel off the outer skin of each skinned item, and safely and securely remove it without damaging its contents), and at the same time, improve skin removal efficiency and yield. Can do. Since other effects are the same as those of the above-described embodiment, description thereof is omitted.

(2) The rotating shaft 2 of the rotating structure 4 is inclined downwardly from the input side P1 where a plurality of skinned items can be simultaneously input to the discharge side P2 of the contents that have been peeled off. In addition, each of the plurality of molting shafts 6 extends in parallel along the same direction as the rotating shaft 2 inclined in a descending gradient, and is circumferentially concentrically around the rotating shaft 2. Are provided at predetermined intervals.

  As shown in FIG. 2, the inclination angle θ of the rotary shaft 2 and each molting shaft 6 inclined in the same direction is defined as an angle (gradient) formed by the rotation center axis Ax of the rotary shaft 2 with respect to the horizontal plane H. be able to. In this case, for example, the inclination angle θ is arbitrarily set according to the purpose and environment of use of the automatic peeling machine, the size and type of the skin-attached object, and the numerical value is not particularly limited here.

  As described above, according to the present technical idea (2), since each molting shaft 6 is inclined downwardly from the input side P1 toward the discharge side P2, a large amount of material supplied from the input side P1 can be obtained. The peeled material is peeled off by each peeling shaft 6 and separated into an outer skin and contents, and only the contents can be discharged and collected from the discharge side P2. Since other effects are the same as those of the above-described embodiment, description thereof is omitted.

(3) On the discharge side P2 of the contents that have been subjected to the molting treatment, the plural molting shafts 6 each have an outer diameter that is smaller than that of the other parts. The gap G2 (see FIG. 1B and FIG. 2) is widened.

  In this case, the discharge side P <b> 2 of each molting shaft 6 is configured with a reduced diameter portion 6 c, and the gap G <b> 2 between the reduced diameter portions 6 c is smaller than other outer diameter dimensions of the molting shaft 6. Is set too small. In addition, since the diameter and range of each reduced-diameter part 6c are arbitrarily set according to, for example, the purpose and environment of use of the automatic molting device, or the size and type of the skinned item, there is no particular limitation here. .

  As described above, according to the present technical idea (3), by forming the reduced-diameter portion 6c on the discharge side P2 of each molting shaft 6, the contents that have been subjected to the molting treatment and separated from the outer skin are discharged to the discharge side P2. In FIG. 5, the gas can be efficiently discharged from the widened gap G2 between the respective diameter-reduced portions 6c of each of the skinning shafts 6. At this time, by arranging the recovery hopper 38 on the discharge side P2, a large amount of contents discharged from the gap G2 can be recovered efficiently without leakage. Since other effects are the same as those of the above-described embodiment, description thereof is omitted.
