  Next, the container unit 20 will be described with reference to FIGS. 2 and 3 together with FIG. The eight container units 20 attached to the rotary support 16 have substantially the same configuration, and one of them will be described below.

  The illustrated container unit 20 includes two storage containers 34 that are spaced apart from each other in a predetermined direction (a direction perpendicular to the paper surface in FIGS. 1 and 3 and a left-right direction in FIG. 2). A thin skin covering (for example, garlic or the like) is stored in the storage container 34 and the skin is peeled off. In this embodiment, in relation to this, in the supply area K, the supply cylindrical body 24 and the configuration related thereto are provided corresponding to each storage container 34, and in the thin skin peeling area P, Corresponding to each storage container 24, a thin skin peeling means 36 and a configuration related thereto are provided, and in the discharge area D, a recovery means 60 is provided in common for the two storage containers 34.

  The container unit 20 further includes a rectangular unit base member 78 and a container holding member 80 disposed above the unit base member 78. The container holding member 80 corresponds to each storage container 34. Through-openings 82 are provided, and an enlarged diameter step 84 is provided at the lower end of each through-opening 82. The storage container 34 has a bowl-like shape with an open upper surface. A substantially hemispherical storage space 85 is defined inside the storage container 34, and a thin skin covering (for example, garlic) is stored in the storage space 85.

  The container unit 20 is assembled as follows. The pair of storage containers 34 is placed at a predetermined position of the unit base member 78, and the container holding member 80 is placed on the upper side of the pair of storage containers 34 so that the opening of the storage container 34 corresponding to the inside of the enlarged diameter step portion 84 is positioned. Put it on. In this state, a pair of intermediate connection members 86 (only one is shown in FIG. 2) is interposed between the unit base member 78 and the container holding member 80, and mounting screws are passed through the unit base member 78 from the outside. 88 is screwed to the intermediate connection member 86, and the fixing screw 90 is fixed to the intermediate connection member 86 through the container clamping member 80 from the outside. When assembled in this manner, the pair of storage containers 34 is sandwiched between the unit base member 78 and the container sandwiching member 80 and assembled in the state shown in FIGS. In this assembled state, the opening of the storage container 34 is aligned with the through-opening 82 of the container holding member 80, and the thin skin covering (for example, garlic etc.) passes through the through-opening 82 of the container holding member 80. The thin skin covering in the storage container 34 is discharged through the through-opening 82.

  In this embodiment, as shown in FIG. 3, an O-ring 91 made of, for example, synthetic rubber is disposed in the diameter-expanded step portion 84 of the container holding member 80, and the opening of the storage container 34 It is attached to the container holding member 80 via the O-ring 91, and the space between the storage container 34 and the container holding member 80 is sealed by the O-ring 91.

  In this embodiment, the container unit 20 rotates integrally with the rotary support 16 along the inner circumferential surface of the arcuate inner wall 44 of the thin-skin recovery member 42 along its inner circumferential surface, as shown in FIG. The central portion of the container clamping member 80 (the direction perpendicular to the paper surface in FIG. 2, the left-right direction in FIG. 3) protrudes somewhat outward in the radial direction from its both ends, and its upper surface is formed in a circular arc shape. With this configuration, the distance between the inner peripheral surface of the arc-shaped inner wall portion 44 and the upper surface of the container holding member 80 of the container unit 20 can be reduced.

  Further, in connection with the above-described configuration of the container unit 20 (that is, the container holding member 78), the auxiliary cylindrical body 92 is attached to the lower end portion of the thin-film discharge cylindrical body 40. The auxiliary cylindrical body 92 protrudes somewhat from the lower end portion of the thin skin discharging cylindrical body 40 toward the thin skin peeling region P, and the tip end surface thereof is an arc concave shape that is substantially continuous with the arc-shaped inner wall portion 44 of the thin skin recovery member 42. By providing the auxiliary cylindrical body 92 in this manner, the thin skin discharge cylindrical body 40 (specifically, the auxiliary cylindrical body 92) and the container unit 20 in the thin skin peeling area P are formed. Specifically, the distance from the container clamping member 80 can be reduced. Instead of providing the auxiliary cylindrical body 92, the distal end portion (lower end portion) of the thin skin discharging cylindrical body 40 may be formed in an arcuate concave shape.

  The container unit 20 is detachably attached to each attachment support portion 18 of the rotation support body 16 as follows. In this embodiment, guide means 94 is disposed at the four corners of each mounting support 18 (FIG. 2 shows two on one side and FIG. 3 shows two on one end). Each guide means 94 has substantially the same configuration, and includes a plate-shaped guide member 96 and a spacer member 98. By attaching the mounting screw 100 to the mounting support portion 18 through the guide member 96 and the spacer 98, the guide means 94 is provided. The member 96 is attached at a predetermined interval (that is, the thickness of the spacer 98) from the support surface of the attachment support portion 18. The guide member 96 extends inward, and a guide groove 102 is defined between the guide member 96 and the support surface of the attachment support portion 18.

  Moreover, the recessed part 104 is provided in the both sides of the unit base member 78 of the container unit 20, and these recessed parts 104 are extended in the longitudinal direction (The left-right direction in FIG. 2, The direction perpendicular | vertical to the paper surface in FIG. 3). The guide members 96 of the guide means 94 on both sides are located in the concave portion 104 of the unit base member 78 from both sides, so that both sides of the unit base member 78 are slidable in the longitudinal direction along the guide grooves 102 of the guide means 94. When the container unit 20 is moved to the mounting position shown in FIG. 2 in the direction indicated by the arrow 106 (FIG. 2), the container unit 20 is mounted on the mounting support portion 18 of the rotary support 16 and from the mounting position by the arrow 108. When moved in the direction shown, the container unit 20 is detached from the mounting support 18.

  In this embodiment, an abutting protrusion 110 that protrudes upward is provided at one end of the mounting support 18 of the rotary support 16 (the end on the tip side in the mounting direction indicated by the arrow 106, the right end in FIG. 2). It has been. Therefore, when the container unit 20 is moved to the mounting position in the mounting direction indicated by the arrow 106, the tip of the unit base member 78 contacts the contact protrusion 110, thereby exceeding the mounting position of the container unit 20. Movement is prevented. The container unit 20 (specifically, the storage container 34) is preferably held in a horizontal or substantially horizontal state as shown in FIGS. 1 to 3 and 5 in the thin skin peeling area P. By maintaining the horizontal or substantially horizontal state, the compressed air from the compressed air injection means 38 can be applied to the thin skin covering (for example, garlic) in the container 34 as required, as will be described later.

  In this embodiment, there is also provided a lock means 112 for releasably locking and holding the container unit 20 at the mounting position (see FIG. 2). The locking means 112 is a per se known snap lock, and includes a first member 116 having a locking portion 114 and a second member 120 having an operation portion 118, and an intermediate portion of the second member 120. Is supported rotatably on a mounting portion 126 of a mounting member 124 mounted on the back surface of the unit base member 78 via a pin 128, and the front end portion of the second member 120 is the rear end of the first member 116. It is connected to the part via a pin 130 so as to be rotatable. A locking member 134 having a locking claw portion 132 is fixed to the back surface of the unit base member 78, and the locking portion 114 of the first member 116 is releasably locked to the locking claw portion 132. .

  In this locking means 112, the locking portion 114 of the first member 116 is locked to the locking claw portion 132 of the locking member 134 on the container unit 20 side, and the second member 120 is centered on the pin 128 in this state. In FIG. 2, when the lock means 112 is rotated counterclockwise to a lock position indicated by a solid line, the lock means 112 is held in a locked state. When in the locked state, the container unit 20 is moved in the mounting direction indicated by the arrow 106 via the locking member 134, and the unit base member 78 abuts against the abutment protrusion 110 of the attachment support portion 18. The unit 20 is locked and held at the mounting position. Further, when the second member 120 is rotated around the pin 128 to the release position indicated by a two-dot chain line in FIG. 2 in the clockwise direction, the lock unit 112 is unlocked. In this state, as understood from FIG. 2, the locked state between the locking member 134 on the container unit 20 side and the locking portion 114 of the first member 116 can be released, and the locked state of both is released. The container unit 20 can be detached from the attachment support portion 18 of the support rotating body 16 by moving the container unit 20 in the removal direction indicated by the arrow 108.

  In this embodiment, the container unit 20 is detachably attached to the mounting support portion 18 of the support rotating body 16 using the lock means 112. However, instead of such a lock means 112, for example, a fixing bolt Further, it may be attached to the attachment support portion 18 so as to be removable using fixing means such as a nut.

  In this thin skin peeling machine, the compressed air injection means 38 described above is disposed corresponding to the thin skin peeling area P (specifically, the container 34 located in the thin skin peeling area P). In this embodiment, since the container unit 20 is provided with the two storage containers 34, the compressed air injection means 38 is provided corresponding to each of the storage containers 34.

  Referring to FIGS. 4 and 5 together with FIG. 1, the illustrated compressed air injection means 38 includes an injection nozzle 142 for injecting compressed air, and the injection nozzle 142 is supplied with a compressed air supply line 144 (for example, a feed line). It is connected to a compressed air supply source 146 via a supply pipe). The compressed air supply source 146 is composed of, for example, a compressor, and the compressed air from the compressed air supply source 146 is supplied to the injection nozzle 142 through the compressed air supply line 144.

  The compressed air from the injection nozzle 142 is preferably injected toward the inner peripheral surface of the storage container 34 as follows. As shown in FIG. 5, the compressed air injected from the injection nozzle 142 is preferably injected obliquely downward toward the inner peripheral surface of the storage container 34, and more specifically, the horizontal direction of the storage container 34. The inclination angle α with respect to the axis L is preferably 15 to 45 degrees, and more preferably 20 to 35. The horizontal axis L here refers to a horizontal axis that is not related to the inclination of the container 34.

  Regarding the inclination angle α in the injection direction of the compressed air, when the inclination angle α is greater than 45 degrees, the compressed air injected from the injection nozzle 142 acts to push down the thin skin covering (for example, garlic), Accordingly, the accommodated thin skin covering is moved toward the bottom of the accommodation container 34, and it is difficult to effectively move it in the circumferential direction along the inner peripheral surface thereof. Further, when the inclination angle α is smaller than 15 degrees, the compressed air from the injection nozzle 142 acts to push the thin skin covering upward, so that the stored thin skin covering is directed toward the opening of the storage container 34. In this case, it is difficult to effectively move the container 34 along the inner peripheral surface in the circumferential direction.

  Moreover, as shown in FIG. 4, it is desirable that the compressed air injected from the injection nozzle 142 is injected toward the tangential direction of the inner peripheral surface of the storage container 34. When jetted in the tangential direction in this manner, the thin skin coating is moved along the inner peripheral surface of the container 34 by the jetted compressed air, and thereby, the compressed air from the jet nozzle 142 is effectively applied to the thin skin coating. Can act.

  The compressed air from the injection nozzle 142 is preferably injected toward the upper part of the inner peripheral surface of the storage container 34, and this injection position P is determined when the entire depth of the storage container 34 is H. The depth H1 from the opening end is preferably (1/5 to 1/2) H (1 / 5H ≦ H1 ≦ 1 / 2H), and (1/5 to 1/3) H (1 / 5H). ≦ H1 ≦ 1 / 3H) is more preferable.

  In connection with the fact that the compressed air from the compressed air injection means 38 is injected toward the container 34 in the thin skin peeling area P, a plurality of air outflow holes are formed in the thin skin discharge tubular body 40 as shown in FIG. 148 may be provided. When a plurality of air outflow holes 148 are provided in this way, a part of the compressed air injected from the compressed air injection means 38 (injection nozzle 142) toward the inner peripheral surface of the storage container 34 passes through these air outflow holes 148. As a result, the amount of compressed air that flows into the recovery space 51 and flows into the recovery space 51 through the entire thin skin discharge tubular body 40 is reduced. As a result, the thin skin covering in the container 34 is lifted by the compressed air flow. Thus, it is possible to suppress the floating to the inside of the thin skin discharging cylindrical body 40.

  In this thin skin peeling machine, the thin skin on the surface of the thin skin covering (for example, garlic) is peeled as follows. Referring mainly to FIGS. 1, 4, and 5, when the rotation support 16 is intermittently rotated in the direction indicated by the arrow 22 and the container unit 20 is positioned in the supply area K, the container of the container unit 20 is accommodated. 34 is supplied with a skin covering (eg, garlic, etc.) to be peeled off. In this supply, the opening / closing member 28 is positioned at the open position shown by a solid line in FIG. 1, and in such an open state, the thin skin coating is supplied to the receiving container 34 through the supply cylinder 24.

  When the rotary support 16 is rotated in the direction indicated by the arrow 22 and the container unit 20 (container container 34) containing the thin skin covering is moved from the supply area K to the thin skin peeling area P, the compressed air injection means Compressed air from 38 (injection nozzle 142) is injected toward the inner peripheral surface of the storage container 34 of the container unit 20 as described above. At this time, since this compressed air is injected obliquely downward toward the inner peripheral surface of the container 34 and in a tangential direction of this inner peripheral surface, the compressed air flows along the inner peripheral surface in the form of a tornado. As a result, the thin skin covering is moved in the circumferential direction along the inner peripheral surface of the container 34. And while rotating many times along the internal peripheral surface of the storage container 34, the compressed air from the compressed air injection means 38 (injection nozzle 142) flows between the thin skin covering and the thin skin on the surface. The thin skin is crushed by the pressure of the inflowing air and peeled off from the surface of the thin skin coating. In this way, the thin skin is peeled off from the thin skin coating using the compressed air.

  Most of the thin skin peeled off from the thin skin covering is collected in the recovery space 51 through the thin skin discharge cylindrical body 40 together with the flow of compressed air, and a part (relatively small) of the thin skin is removed. Is recovered in the recovery space 51 through the air outflow hole 148 (see FIG. 3).

  Thereafter, when the rotary support 16 is rotated in the direction indicated by the arrow 22 and the container unit 20 (accommodating container 34) that accommodates the thin skin covering from which the thin skin has been peeled moves from the thin skin peeling area P to the discharge area D, The product falls from the container unit 20 (the storage container 34) and is recovered by the recovery means 60 (the recovery container 62). Thus, while the container unit 20 (container 34) is moved through the supply area K, the thin skin peeling area P, and the discharge area D, the thin skin coating (for example, garlic) supplied in the supply area K is After the thin skin on the surface is peeled off in the thin skin peeling area P, it is discharged in the discharge area D, and the thin skin of the thin skin coating can be automatically peeled while the container unit 20 moves as required.

  As mentioned above, although one Embodiment of the thinning machine according to this invention was described, this invention is not limited to this Embodiment, A various deformation | transformation thru | or correction | amendment are possible without deviating from the scope of the present invention.

  For example, in the above-described embodiment, two container containers are provided in one container unit to form a two-row structure. For example, when the structure of the thinning machine is to be simplified and reduced in size, one container unit is accommodated in one container unit. Containers may be provided to form a one-row configuration, and when the working efficiency is increased, three or more storage containers may be provided in the container unit to form a three-row or more configuration.

  Further, for example, in the embodiment described above, the outer shape of the rotation support body is formed in an octagonal shape, and a total of eight container units are attached to the attachment support portion. The body may be formed into an appropriate polygonal shape such as a quadrangular shape or a hexagonal shape. For example, in the case of a quadrangular shape (hexagonal shape), a total of four (six) container units are attached and supported. Can be attached to the part.

  Further, for example, in the above-described embodiment, the container unit (container) is attached to the attachment support portion of the rotation support and moved in a predetermined direction through the supply area, the skin peeling area, and the discharge area. However, the rotary support described above may be omitted, the container may be fixedly provided, and the compressed air from the compressed air injection means (injection nozzle) may be injected as required to peel off the skin. The same can be applied to such a thing.
