Utility Model Registration No. 3180683 JP 2005-1181010 A

  The fruit vegetable skinning device is required to be able to cope with various shapes and sizes of fruit vegetables to be skinned. For example, the carp has a rounded and rounded carp (Furuyu carp), a long and slender scissor-shaped carp (brush carp), and a vertically long and tapered bell. There are various shapes of cocoons depending on the place of production, such as a cocoon (bee shop) and a square-shaped flat cocoon (Hirakumu-no-Mori, Shonai 柿). Therefore, the skinning device can also cope with various shapes and sizes, and even when setting adjustment for this is required, it is required that the adjustment be simple. Of course, it is desirable that there is no unpeeling in the skinning operation.

  Furthermore, in the case where the holding unit of the skinning device is provided with a fixed needle, it is necessary to pierce the fixed needle deeply in order to hold the fruit and vegetable, but when pulling out the fruit and vegetable with the fixed needle inserted deeply from the fixed needle. In addition, it is difficult to grasp and pull out fruit vegetables having increased lubricity due to the load, moisture, etc. adhering to the surface as compared to before peeling. Further, since the fixed needle and the fruit vegetables are brought into close contact with each other due to the restoring force inside the fruit vegetables, the resistance is greater than when piercing.

  Therefore, the present invention has been made in view of the above points, and can reliably peel fruit vegetables of various sizes and shapes, is small and easy to transport and store, and is easy to adjust and maintain. Thus, an object of the present invention is to provide a skin peeling apparatus having a configuration capable of reliably recovering peeled fruit vegetables from a fixed needle with a small force.

  In order to achieve the above-described object, the skin peeling device according to the present invention includes a work support portion in which a work holder that supports peelable fruit and vegetables is rotatably arranged by driving a work rotation motor, A peeler shaft that holds a peeler that supports the peeler blade with a peeler arm, rotates by driving a peeler rotation motor, and moves the peeler along the outer periphery of the fruit vegetables supported by the work holder, and is arranged coaxially with the peeler shaft The other end of the urging member having one end connected to the peeler is connected to a position separated from the peeler shaft in the radial direction, and a peeler drive that rotatably supports a central shaft that rotates by driving a shaft rotation motor And a control unit that controls driving of the workpiece rotation motor, the peeler rotation motor, and the shaft rotation motor, and the peeler driving unit includes the peeler driving unit. The tensioning state of the urging member is adjusted according to the rotation angle difference between the center shaft and the center shaft, and the peeler blade is configured to be swingable so as to be in contact with and away from the virtual axis of the peeler shaft. To do.

The skinning apparatus having such a configuration enables the following skinning by controlling the drive of each motor.
1) Rotate the work holder holding the fruit vegetables.
2) The peeler is pulled toward the petal direction by rotating the first angle in advance of the central shaft and strengthening the biasing member. Thus, the peeler can be brought into contact with the fruit vegetables. That is, the first angle is an angle for bringing the peeler into contact with the fruit vegetables and further adjusting the pressure of the contact, and is an angle from the origin. The origin is the angular position at which skinning starts. It is not limited to a certain angular position on the rotation trajectory of the peeler. Further, as described above, the first angle is a rotation angle difference between the peeler shaft and the central shaft.
3) Synchronize the central shaft and the peeler shaft to rotate the second angle. Skinning is performed during the rotation of the peeler shaft. During this time, the rotation angle difference between the center shaft and the peeler shaft does not change, so the state (pressure) in which the peeler is in contact with the fruit vegetables remains unchanged. The said 2nd angle means the movement angle on the rotation locus | trajectory (arc) of a peeler in the state which contacted the peeler with fruit vegetables.
4) When the rotation of the second angle is finished, the first angle is reversely rotated in advance of the central shaft. As a result, the contact of the peeler with the fruit vegetables is released.
5) Thereafter, the central shaft and the peeler axis are synchronized to rotate the second angle in the reverse direction to return to the original position (origin).
6) Stop the rotation of the work holder.

  In the embodiment to be described later, an apparatus for skinning a spherical fruit vegetable is assumed. In this way, for the skin peeling of a spherical fruit vegetable, the above-described origin (0 °) is held on a work holder. It can be realized by setting it to be in the vicinity of the holder body and to finish peeling at 180 °.

  Assuming the case of peeling a cylindrical fruit vegetable such as a thick radish, the origin is set at a 45 ° position in the case of a spherical fruit vegetable, and the skin is peeled at a 135 ° position. By setting so as to be finished, the side surface of the radish can be peeled off.

  Thus, according to this invention, it becomes possible to adjust the position of the peeler of a peeling apparatus according to the average shape of the target fruit and vegetables.

  Further, the peeler is supported by the peeler arm by extending the peeler blade in a moving direction by rotation of the peeler shaft, and the peeler driving unit includes the peeler shaft and the central shaft, the axial direction of which is The present invention is characterized in that it extends at an elevation angle of 20 ° to 25 ° from a surface perpendicular to the rotation axis direction of the work holder and is oriented in the direction of the center of the fruit and vegetables held by the work holder. To do.

  According to such a configuration, even if the contact of the fruit vegetables with the epidermis is always a contact with a point or a short dimension, by arranging the peeler to be inclined with respect to the rotation axis direction, the contacting part is It is possible to extend over a long region in the crossing direction of the peeler blade. Thereby, the adaptability (contact) property of the peeler blade to the shape of the fruit vegetables is improved, and it becomes possible to deal with peeling of fruit vegetables of various sizes and shapes. Detailed description will be given later.

  Furthermore, the peeler drive unit has a peeler mounting plate to which the peeler arm is swingably connected, and the mounting plate is detachably disposed on a tip mounting unit of the peeler shaft. And

  According to such a configuration, it is possible to perform peeling by appropriately selecting a peeler mounting plate equipped with a peeler blade or an arm-shaped peeler according to the fruit and vegetables to be peeled, thereby improving versatility. It becomes. In addition, maintenance such as cleaning and disinfection of the peeler that directly contacts the fruit vegetables becomes simple.

  Further, the work holder includes a holder main body and a fixed needle that pierces and supports a fruit vegetable to be peeled connected to the holder main body, and the work support portion further fixes the central portion in the longitudinal direction of the lever main body. A workpiece abutting member that is pivotally supported by a swing shaft extending in a direction intersecting with the direction in which the needle extends and disposed at one end of the lever main body in the longitudinal direction is an upper surface of the holder main body. Ejecting operation in the vicinity of the intermediate position in the longitudinal direction of the fixed needle from the initial position of the ejecting operation that is substantially flush and does not contact with the fruit vegetables supported by the work holder, through the position in contact with the holder main body vicinity of the fruit vegetables An eject lever that is reciprocally movable to a completion position is provided.

It can be in a state of being inserted shallowly. In this way, the fruits and vegetables that have been peeled off are not inadvertently rolled by placing the fruits and vegetables held on the fixed needle in a shallow state without being completely mechanically pulled out. Also, by separating the close contact between the fixed needle and the fruit vegetables, the resistance when pulling out the fruit vegetables is reduced, so that the operator can easily pull out the fruit vegetables from the fixed needle, and it is safe and hygienic without having to grip firmly. You can proceed to work.

  Hereinafter, as an embodiment of a skinning device according to the present invention, a tabletop skinning device used as a whole-skinning processing device for substantially spherical fruit vegetables such as persimmons will be described with reference to FIGS. 1 to 11. I will explain.

  As shown in FIGS. 1 and 2, the peeling apparatus of the present embodiment includes a thin plate-like substantially rectangular stacking board 20 disposed in an apparatus main body 1 described later, The peeler 101 including the peeler blade 102 can be freely attached to and detached from a fruit vegetable W (referred to as a “workpiece” in this specification) that is supported by a work holder 161 described later, and A peeler driving unit 100 that holds the peeler 101 rotatably along the outer periphery of the workpiece W is disposed.

  The peeler driving unit 100 is rotatable by driving of the peeler rotating motor 110, and supports a hollow peeler shaft 111 having an inner hole on the shaft rack 108. The peeler shaft 111 is placed on the shaft rack 108. The peeler is connected via a drive transmission system including a tension belt 114 wound between a motor pulley 112 disposed on the rotation shaft 110a of the peeler rotation motor 110 and a peeler shaft pulley 113 disposed on the peeler shaft 111. The driving force of the rotary motor 110 is transmitted to enable rotation. The peeler shaft 111 has a slit (not shown) that allows the detection light of the optical sensor (peeler axis position detection sensor) 116 having a detection light emitting portion and a light receiving portion disposed in the shaft rack 108 to pass therethrough. Two peeler shaft sensor plates 115 (180 ° apart) formed on the circumference of the circular rotating body are disposed, and the peeler shaft position detection sensor 116 detects the detection light, thereby rotating the rotational position. (Rotation amount) can be detected. The slit forming angle corresponds to the second angle described above.

  Here, the peeler 101 includes a peeler blade 102 and a pair of arm-like peeler arms 103 that support the peeler blade 102 along the surface of the workpiece W so as to be swingable. The peeler driving unit 100 includes a peeler mounting plate 105 for connecting the base end portion of the peeler arm 103 via a pair of hinges 104. The peeler mounting plate 105 supports the peeler blade 102 located on the tip end side of the peeler 101 so as to be swingable so as to be in contact with and away from the virtual axis of the peeler shaft 111. The peeler mounting plate 105 is detachably disposed on the peeler mounting portion 111a formed at the tip of the peeler shaft 111 so that the intermediate portion of the pair of hinges 104 is positioned on the rotation shaft of the peeler shaft 111. Has been.

  Further, the shaft rack 108 is configured such that the engagement pin 121 of the rotation lock member 120 is swingable in a direction to come in contact with and separate from the peeler shaft 111 by pivotally supporting the rear end thereof. The spring member 122 is stretched between the spring 108 and the spring member 122 so as to be always urged in the peeler axis direction. Further, the peeler shaft 111 is made of a substantially circular rotating body, and when the peeler shaft 111 rotates in one rotation direction, the engagement pin 121 is engaged to lock the rotation of the peeler shaft 111. 120 lock rotating bodies 123 are provided. In the present embodiment, the lock rotator 123 has a circumferential region that gradually decreases in diameter in the one rotation direction, and the engagement pin 121 is positioned downstream in the rotation direction when rotating in the one rotation direction. It is formed so as to come into contact with a contact wall (not shown) in the circumferential region.

  In the present embodiment, the lock rotator 123 has the origin at which the peeler shaft 111 becomes an initial peel angle when the engagement pin 121 is engaged with its circumferential region and the rotation is locked. It arrange | positions so that it may be located in.

  Further, the peeler driving unit 100 extends coaxially in the shaft inner hole of the peeler shaft 111 so that one end thereof faces the workpiece support 160 side from the peeler mounting plate 105 and can be rotated by the shaft rotation motor 140. The center shaft 141 is supported on the shaft rack 108. The center shaft 141 is a rotating shaft for operating a coil spring 148 as an urging member for bringing the peeler 101 into contact with the workpiece W, and is attached to the driving shaft 140a of the shaft rotating motor 140 mounted on the shaft rack 108. The driving force of the shaft rotation motor 140 is transmitted through a drive transmission system comprising a tension belt 144 wound between the arranged motor pulley 142 and the shaft shaft pulley 143 arranged on the central shaft 141. It can be turned.

  In the center shaft 141, a slit 145a that passes through the detection light of a light sensor (shaft position detection sensor) 146 that is disposed on the shaft rack 108 and has a light emitting portion and a light receiving portion for detection light is a circular rotating body. One shaft shaft sensor plate 145 is disposed on the circumference of the shaft, and the shaft position detection sensor 146 can detect the rotation position (rotation amount) by detecting the detection light. .

  A tip flange 141a is formed at one end of the central shaft 141 facing the workpiece support 160 from the peeler mounting plate 105. An urging member connecting portion 147 is formed on the outer peripheral portion of the front end flange 141a. The urging member connecting portion 147 is stretched between the peeler 101 and the center shaft 141 and / or the peeler shaft 111. One end of a coil spring 148 is connected as an urging member capable of changing the tension state by rotation and adjusting the contact / separation state of the peeler 101 with respect to the workpiece W. In FIG. 2, illustration of a screw member that connects the urging member connecting portion 147 and one end of the coil spring 148 is omitted. In the present embodiment, the other end of the coil spring 148 is an urging member engaging portion formed at the center portion of the peeler rib 106 disposed so as to extend in parallel with the peeler blade 102 between the peeler arms 103 of the peeler 101. 107 is connected.

  In the present embodiment, the peeler driving unit 100 sets the shaft rack 108 to an angle of elevation of 25 ° from a surface (a surface parallel to the loading substrate 20) perpendicular to the axial direction of the work holder 161, which will be described later. On the other hand, it is supported on the stacked substrate 20 so as to be directed toward the center of the workpiece W held by the workpiece holder 161. As a result, the contact area of the peeler blade 102 with the skin of the spherical workpiece W can be extended over a long range in the blade crossing direction of the peeler blade 102.

  FIG. 3 is a conceptual explanatory diagram for determining the inclination angle of the peeler shaft 111 that is optimal for peeling off the spherical workpiece W (in FIG. 3, the plain core is shown as a solid line).

  When determining the inclination angle of the peeler shaft 111, when there is only one kind of workpiece W to be peeled, the workpiece W having a standard size (height in the axial direction) and the workpiece W to be peeled off Are a plurality of types, the workpiece W having the smallest standard size is determined as a reference (hereinafter, the reference workpiece W is referred to as a sample workpiece SW).

  In FIG. 3, a point A indicates a starting point for peeling off the sample work SW. The point A is located at a position closest to the axis, and can avoid buffering with the workpiece support portion 200 that rotatably supports the sample workpiece SW. Point B indicates the end point of peeling of the sample work SW, and is taken on the rotation axis of the sample work SW, that is, on the rotation axis of the workpiece support 161 described later. Further, the center point of the circle including the points A and B is taken on the point A side with respect to the sample work SW and is set as a point C, and an intermediate point between the points A and B is set as a point D.

  The circle indicates a trajectory on the axial plane of the peeler blade 102 of the peeler 101 that swings (rotates) around the point C, that is, a trajectory at the center in the length direction of the peeler blade 102. In the present embodiment, the point C is the position of the intersection of the shaft of the pair of hinges 104 (virtual portion of the shaft) and the peeler shaft 111 that swingably mounts the peeler arm 103 to the peeler mounting plate 105.

  Then, an angle of inclination (elevation angle) from a plane perpendicular to the rotation axis direction of the work holder 161 is obtained with the line segment connecting the point C and the point D as the axial direction of the peeler shaft 111.

  As described above, the reason why the line connecting the point C and the intermediate point (point D) between the point A and the point B is the axial direction of the peeler shaft 111 is that the tension on the workpiece W of the peeler blade 102 of the peeler 101 is set. This is to make it uniform. For example, when the point D is set closer to the point B (the inclination angle of the peeler shaft 111 is smaller than that when the point D is set at the intermediate point), the tension on the point B side with respect to the workpiece W is It is weak, and the tension on the point A side is strong, and on the B side where the tension is weak, it is easy to cause adverse effects such as poor peeling. Since the phenomenon of unpeeling often occurs especially at the zenith portion where the peeling end point is reached, it is desirable that the tension of the peeler 101 is set to be uniform with respect to the workpiece W or to be stronger on the peeling end point side.

  Then, in the apparatus set in accordance with the sample work SW as described above, when peeling the work W larger than the sample work SW (in FIG. 3, the bee jar is shown by a two-dot broken line), FIG. The peeling end point of the large workpiece W, indicated by point E on the circle, is off the top of the workpiece W, so that the peeler blade 102 does not reach the tip of the heel on the axial plane so that peeling cannot be performed. appear. However, by supporting the peeler shaft 101 at the inclination angle as described above, the front end of the peeler blade 102 reaches the point E immediately before the center of the peeler blade 102 of the peeler 101 reaches the point E. The skin of the point E portion can also be peeled off.

  As described above, when the peeler 101 held by the peeler shaft 111 that is inclined at a certain angle with respect to the rotation axis of the workpiece W is used, any part in the length direction of the peeler blade 102 is applied to substantially the entire surface of the skin. It can be contacted and can be peeled without leaving any residue.

  In addition, the apparatus of this embodiment may be provided with the structure which can adjust the position and inclination | tilt angle of the peeler axis | shaft 111. FIG. For example, the shaft rack 108 is supported by a support member (not shown), and the shaft rack 108 and the support member can be moved in the longitudinal direction of the apparatus body 1, or can be moved in a direction orthogonal to the stacking substrate 20. It is good also as a structure which can adjust the inclination angle (elevation angle) of 20 degrees-25 degrees.

  Further, on the other end side in the longitudinal direction of the stacking substrate 20, a work support portion 160 is formed, and a work holder 161 for supporting the work W so as to be peeled off is disposed so as to be rotatable around the axial direction. .

  Next, the drive control and operation of the apparatus of the present embodiment will be described by taking as an example the case of peeling off a substantially fist-sized spherical workpiece W such as a spear.

  As described above, the first angle and the second angle described above are preferably 180 ° for skinning the spherical workpiece W. Therefore, in the present embodiment, with respect to the peeler rotation motor 110 of the peeler driving unit 100, the peeler shaft 111 in a state where the peeler blade 102 of the peeler 101 extends in the width direction of the apparatus base 2a at the lowermost part in the rotation trajectory. The angle position is defined as the origin (defined as 0 °), and rotated when the peeler blade 102 is moved to the top by rotating about 180 ° counterclockwise in a state facing the peeler driving unit 100 from the origin. The drive is controlled so as to stop.

  Further, the shaft rotation motor 140 has an angular position in a state in which the urging member connecting portion 147 formed on the front end flange 141a of the central shaft 141 is closest to the lowermost part in the rotation trajectory of the peeler blade 102, that is, the origin. The drive is controlled so as to rotate around the axis with reference to. The peeler rotation motor 110 and the shaft rotation motor 140 are electrically synchronized.

  The rotation speed of the work rotation motor 164 can be adjusted by an input signal transmitted from the adjustment input means 210 to the control unit 200. As an initial setting, the rotation of the work rotation motor 164 is about 300 rotations / minute. It is desirable from the viewpoint of efficiency that the peeler blade 102 is moved to the uppermost portion during about 10 to 50 rotations of the workpiece W.

  The rotation of the peeler rotation motor 110 and the workpiece rotation motor 164 is finely adjusted by the input signals transmitted from the adjustment input means 220 and 210 to the control unit 200, respectively. It can be performed.

  In the present embodiment, the control unit 200 determines that the peeler shaft 111 and the central shaft 141 have rotated a predetermined angle based on the rotation amount detection results using the optical sensors 116 and 146 described above. . Of course, the detection method of the rotation amount of each axis is not limited to this method.

  Hereinafter, a description will be given using the flowchart of FIG.

  First, the peeling device is placed on the table, the lid 3 is opened, the main power is turned on, and the peeling operation switch 5 is turned on (see FIG. 7).

  Further, the user pierces the work pin 163 of the work holder 161 to hold the position of the work W while the work holder 161 is rotating. At this time, the center of gravity of the work W is pierced by the work pin 163.

  When the workpiece W is held by the workpiece holder 161, the operation switch 5 is turned on. Note that further switch operation of the operation switch 5 during the skinning operation controls driving as a skinning stop operation (OFF operation).

  When detecting the ON operation, the control unit 200 drives the work rotation motor 164. The driving force of the work rotation motor 167 is transmitted from the rotation shaft 167a to the motor pulley 168, the timing belt 197, the work pulley 166, and the work rotation shaft 165, and rotates the work W together with the work holder 161. During this time, the ejector pulley 193 around which the timing belt 197 is wound is restrained from rotating, so that the eject lever 170 does not swing.

  Further, the control unit 200 drives the shaft rotation motor 140. The driving force of the shaft rotation motor 140 is transmitted from the driving shaft to the motor pulley 147, the tension belt 144, and the shaft shaft pulley 143, and the central shaft 141 is counterclockwise in a state where the central shaft 141 faces the peeler driving unit 100 from the origin. Rotate by 180 ° (first angle).

  By this rotation, the coil spring 148 stretched between the urging member engaging portion 107 of the peeler 101 held by the peeler shaft 111 and the urging member connecting portion 147 of the center shaft 141 is expanded, and the peeler 101 is extended. A strong tension that draws the tip end side of the peeler against the virtual axis of the peeler shaft 111 is exerted. The peeler 101 swings at the base portion of the peeler arm 103 due to this tension, and presses the peeler blade 102 against a portion of the rotating workpiece W located near the holder main body 162 (see FIG. 8).

  Subsequently, the control unit 200 drives the shaft rotation motor 140 and the peeler rotation motor 110 while being electrically synchronized. The center shaft 141 is further rotated by 180 ° (second angle) in the same direction by this driving. The driving force of the peeler rotating motor 110 is transmitted from the rotating shaft 110a to the motor pulley 112, the tension belt 114, and the peeler shaft pulley 113, and the peeler shaft 111 is counterclockwise when facing the peeler driving unit 100 from the origin. Rotate by 180 ° (second angle).

  The peeler 101 moves the peeler blade 102 to the top by the rotation of the peeler shaft 111 (see FIG. 9). In this embodiment, during this time, the central shaft 141 rotates together with the peeler shaft 111, so that the tension state of the coil spring 148 that presses the peeler 101 against the workpiece W does not change greatly. Can be held. The peeler 101 that gradually moves the contact position with the workpiece W upward by the rotation of the peeler shaft 111 continuously waits for the skin of the workpiece W rotating by the rotation of the workpiece rotation shaft 164a on the downstream side in the rotation direction. Continue stripping.

  When the peeler shaft 111 rotates 180 ° (the central shaft 141 is 360 ° in total), the control unit 200 temporarily stops driving the shaft rotation motor 140 and the peeler rotation motor 110.

  In addition to the case where the peeling stop operation (OFF operation) is performed by a further switch operation of the operation switch 5 during the above-described skinning operation, in the apparatus of this embodiment, for example, the work pin of the work holder 161 163 and the peeler 101 come into contact with each other mechanically / electrically or when it is mechanically / electrically determined that the control unit 200 can predict that the subsequent operation will be hindered, or within the device, mechanical / electrical / thermal When a technical problem occurs, the control unit 200 determines to stop driving each motor, that is, stop the operation of each member. A stop command based on this determination is always accepted during the above operation and processed with priority.

  Subsequently, the shaft rotation motor 140 is driven in the reverse direction, the central shaft 141 is rotated by 180 ° (first angle) in the reverse direction, and the tension state of the coil spring 148 that presses the peeler 101 against the workpiece W. Is released, and the contact of the peeler 101 with the workpiece W is released.

  Subsequently, the control unit 200 stops driving the work rotation motor 164.

  Further, the control unit 200 drives the shaft rotation motor 140 and the peeler rotation motor 110 while being electrically synchronized with each other, and rotates them both reversely by 180 ° (second angle) to return the position to the origin. When the peeler shaft 111 returns to the origin, the engagement pin 121 is engaged with the contact wall formed in the circumferential region of the lock rotating body 123 disposed on the peeler shaft 111, and the mechanical origin position is reached. Matching (locking) is performed.

  The skinning process for the entire circumference of the workpiece W has been completed as described above, but in this embodiment, an ejecting operation using the eject lever 170 of the workpiece W that has been stripped is executed. The ejection operation refers to a period from when the workpiece contact portion 176a of the workpiece contact member main body 176 moves from the ejection operation initial position to the ejection operation completion position and again returns to the ejection operation initial position. Refers to movement.

  The initial position of the ejection operation is a position in the vicinity of the upper surface of the holder body 162 in the present embodiment. The ejection operation completion position is a position that is necessary and sufficient to pull out the workpiece W with one hand. In the present embodiment, the ejection operation completion position is in the vicinity of a ½ length position of the work pin 163.

  In the present embodiment, the control unit 200 drives the work rotation motor 167 so as to rotate in the reverse direction to that during the skinning operation. The driving force of the work rotation motor 167 is transmitted from the rotation shaft 167 a to the motor pulley 168, the timing belt 197, the ejector pulley 193, and the first gear 192 of the lever swing gear unit 190, and the second gear meshing with the first gear 192. The rotating shaft 194b of 194 is rotated in one direction, and the swinging portion side engaging portion 195 disposed on the rotating shaft 194b is swung. The engaging pin 121 of the swinging portion side engaging portion 195 that is swinging is positioned at the upper limit and the lower limit every half rotation, but the engaging pin 195a of the swinging portion side engaging portion 195 is the eject lever. While moving in the long hole 171a of 170, the eject lever 170 is swung by the swing shaft 173 by moving so as to be positioned at the lower limit, and the work contact member 175 is pushed up (see FIG. 10). When the workpiece contact member 175 moves the workpiece contact surface 176a from the ejection operation initial position to the ejection operation completion position, the workpiece contact member 175 contacts the base portion of the workpiece pin 163 of the workpiece W that has been stripped, The workpiece W is moved in a direction to leave the workpiece pin 163 as it is, and the workpiece W is urged to leave the workpiece pin 163. Further, the engaging pin 195a of the swinging portion side engaging portion 195 moves within the elongated hole 171a of the ejecting lever 170 and moves so as to be positioned at the upper limit, so that the ejecting lever 170 is swung by the swinging shaft 173. The workpiece contact member 175 is returned to the original position.

  During the ejector operation, the work pulley 166 around which the timing belt is wound is restrained from rotating, so that the work holder 161 does not rotate. By executing this ejecting operation, even when the work holder 161 is made up of the work pins 163, the work W that has been peeled off can be brought into a state of being shallowly inserted into the work pins 163. In this way, the workpiece W held in a shallowly inserted state is not inadvertently rolled without being mechanically completely pulled out from the workpiece pin 163. Moreover, since the resistance when the operator pulls out the workpiece W is reduced by separating the contact between the workpiece pin 163 and the workpiece W, the workpiece W can be easily pulled out, and the work can be performed safely and hygienically. Can do.

  After the peeled work W is collected from the work holder (see FIG. 11), when the skinning operation is continued, the next work W is inserted into the work pin 163 and the operation switch 5 is turned on. Repeat the operation. During the ejecting operation, the lever driving detection sensor 180 disposed on the stacking substrate 20 emits and receives light through a hole 171b formed at the other longitudinal end of the lever main body 171 to drive the ejecting lever 170. It is determined that the operation has been performed, and control is performed to return the angular positions of the peeler shaft 111 and the central shaft 141 to the origin.

  When the skinning operation is finished, the main power supply is turned off, and the lid 3 is rotated so as to cover the upper side of the other end in the longitudinal direction of the apparatus base 2a. When the skinning device of the present embodiment is moved to another storage location or the like, a locking member (not shown) that locks the opening / closing movement is applied in the closed state of the lid 3, and the handle 4 is held and hung. Can be carried.

  In addition, this invention is not limited to embodiment mentioned above, A various change can be made in the limit which does not impair the characteristic of this invention.
