  As shown in FIGS. 1 and 5, the pressing mechanism 70 includes a support arm portion 71 whose one end is pivotally attached to the mounting plate 64, and a rear arm portion whose other end is pivotally attached in the vicinity of the rear end. 72, a tension spring 73 mounted between the rear end of the rear arm portion 72 and the support arm portion 71, and one end portion thereof are pivotally supported toward the rear of the rear arm portion 72 and on the other side. Two guide plates 74 in which long holes 74a are formed, a front arm part 75 having one end (rear end) fixed to the front end of the rear arm part 72 at a predetermined angle, and other parts of the front arm part 75 A push rod that is attached between the operation portion 76 fixed to the end (front end) and the front arm portion 75 and the rear arm portion 72 and is inserted through the guide hole 62a formed in the horizontal portion 62 so as to be movable up and down. 77.

  In the long holes 74a of the two guide plates 74, protrusions 71a fixed to both sides near one end of the support arm portion 71 are slidably mounted. In addition, a handle 78 is attached to the operation unit 76 so that the operator grips the workpiece when the workpiece is pushed into the insertion path 13. Furthermore, the push rod 77 has a large-diameter portion 77a formed on the base end side and a medium-diameter portion 77b formed on the distal end side. Although not shown, the small diameter portion is detachably attached to the tip of the medium diameter portion 77b to hold the workpiece. In addition, you may make it mount | wear with the front-end | tip of the medium diameter part 77b which has the processus | protrusion planted in multiple numbers by the same length corresponding to the shape, hardness, etc. of a to-be-cut object. Further, when the push rod 77 is pushed into the cutter unit 10, the length of the lower end of the push rod 77 is set so as to reach between the three second cutter members 22 and the two third cutter members 23. .

  In the pressing mechanism 70 configured as described above, when the operator grips and pushes down the handle 78, the rear arm portion 72 and the front arm portion 75 are lowered against the tensile force of the tension spring 73, and the pressing mechanism 70 is pushed accordingly. The rod 77 descends along the guide hole 62a of the horizontal portion 62. When the rear arm portion 72 and the front arm portion 75 are lowered, the two guide plates 74 that are pivotally supported by the rear arm portion 72 are protruded 71a of the support arm portion 71 mounted in the elongated hole 74a. , The push rod 77 can be smoothly lowered.

  Next, the operation of the peeling apparatus of this embodiment will be described. In the description of the operation of the present embodiment, a case where a radish R is used as the workpiece will be described.

  First, after cutting off the leaf portion of the radish R, which is a workpiece, this radish R is formed in openings 15a and 16a in the upper and lower circular plates 15 and 16 of the cutter unit 10 as shown in FIG. insert. Then, the tip of the radish R reaches a position where it faces the three short first cutter members 21 while being guided in the longitudinal center direction of the insertion passage 13 by the plate-like guide springs 18 and 19.

  Next, when the operator grips and lowers the handle 78, the rear arm portion 72 and the front arm portion 75 descend against the tensile force of the tension spring 73, and the push rod 77 is moved along the guide hole of the horizontal portion 62. It descends along 62a. Here, since the length of the lower end of the push rod 77 is set so as to reach between the three second cutter members 22 and the two third cutter members 23, the rear end of the radish R is the push rod 77. The tip of the radish R reaches the fourth cutter member 24 through the first cutter member 21, the second cutter member 22, and the third cutter member 23.

  At this time, the peripheral surface of the radish R comes into contact with the contact guide portions 40 of the respective cutter blades 35 in the first cutter member 21, the second cutter member 22, the third cutter member 23, and the fourth cutter member 24, and the blade portion The skin of the peripheral surface is peeled off by 41. And in this cutting stage, the longitudinal direction of the peripheral surface of the radish R by the cutter blades 35 in the three first cutter members 21 and the second cutter members 22, the two third cutter members 23 and the fourth cutter members 24. A total of 10 strips are peeled to form 10 sides of the dodecagon.

  Further, due to the pressing force of the push rod 77 and the weight of the radish R, the tip of the radish R comes into contact with the contact guide portion 40 of the cutter blade 35 of the fifth cutter member 25, and the peripheral surface is peeled off by the blade portion 41. When peeled in this way, two strips are peeled in the longitudinal direction of the peripheral surface of the radish R, and all 12 sides of the total dodecagon are formed. The skin peeled in this way forms an arcuate shape, is guided from the opening 43 of each cutter blade 35 through the guide piece 42, and is discharged from the substrate 11 of the cutter unit 10 onto the support base 2. The peeled radish R passes through the circular hole 12 of the substrate 11 and the discharge port of the support base 2 and is accommodated in the car 6.

  Next, when the operator grips and lifts the handle 78 of the pressing mechanism 70, the rear arm portion 72 and the front arm portion 75 are raised by the tensile force of the tension spring 73, and the push rod 77 is moved along the horizontal portion 62. It rises along the guide hole 62a. Then, as shown in FIG. 1, the next radish R is inserted into the openings 15 a and 16 a in the upper and lower circular plates 15 and 16 of the cutter unit 10. Thereafter, the above-described process is performed again. By repeating these steps, a large amount of radish R can be peeled in a short time.

  Next, when carrots are peeled off as an object to be cut, the carrot leaves are cut off with a knife, and then the carrots are cut into upper and lower circular hole plates 15 and 16 of the cutter unit 10 as shown in FIG. Are inserted into the openings 15a and 16a. Then, the tip of the carrot is guided by the plate-shaped guide springs 18 and 19 in the longitudinal center direction of the insertion passage 13, and passes through the three short first cutter members 21 and the second cutter member 22, and thereby the third cutter member. A position such as 23 is reached. At this time, when the rear side of the carrot has a large diameter, the blade 41 touches the contact guide portion 40 of the cutter blade 35 in the three short first cutter members 21 and 22, and the skin of the peripheral surface is cut by the blade portion 41. It will be peeled off. In this cutting stage, since the diameter of the front end side of the carrot is generally small, the front end side of the carrot passes through the first cutter member 21 and the second cutter member 22, and the skin is only on the rear side having a large diameter. Is peeled off.

  Next, when the operator grips and pushes down the handle 78 of the pressing mechanism 70, the rear arm portion 72 and the front arm portion 75 are lowered against the tensile force of the tension spring 73, and the push rod 77 is moved along the horizontal portion accordingly. It descends along the guide hole 62a of 62. Here, since the lower end of the push rod 77 is set so as to reach between the three second cutter members 22 and the two third cutter members 23, the rear end of the carrot is pushed by the push rod 77. When pressed, the leading end side of the carrot is in contact guide portions 40 of the respective cutter blades 35 in the two third cutter members 23, the fourth cutter member 24, and the fifth cutter member 25 that are pressed against each other in the lateral (horizontal) direction. The peripheral surface is peeled off by the blade portion 41 in contact. In this way, the entire circumferential direction including the front end side of the carrot can be peeled off.

  Further, when peeling the burdock as a workpiece, the burdock is inserted into the openings 15a and 16a in the upper and lower circular plates 15 and 16 of the cutter unit 10 as shown in FIG. Then, the small-sized burdock is guided to the third cutter member 23 via the three first cutter members 21 and the second cutter member 22 while being guided by the plate-shaped guide springs 18 and 19 in the longitudinal center direction of the insertion passage 13. Reach the position you want to face. At this time, since the burdock generally has a small diameter, the three first cutter members 21 and the second cutter member 22 do not peel the peripheral surface.

  Next, when the operator grips and pushes down the handle 78 of the pressing mechanism 70, the rear arm portion 72 and the front arm portion 75 are lowered against the tensile force of the tension spring 73, and the push rod 77 is moved along the horizontal portion accordingly. It descends along the guide hole 62a of 62. Then, the rear end of the burdock is pressed by the push rod 77, and the burdock is the cutter in the two third cutter members 23, the fourth cutter member 24, and the fifth cutter member 25 that are pressed against each other in the lateral (horizontal) direction. The peripheral surface is peeled off by the blade portion 41 in contact with the contact guide portion 40 of the blade 35. In this way, the entire circumferential direction of the burdock can be peeled, and the horizontal cut surface of the peeled burdock becomes a hexagon. And in the case of bulk vegetables such as potatoes and taro, the skin can be peeled like ginseng and burdock.

  Therefore, in this embodiment, while arrange | positioning three 1st cutter members 21 and 2nd cutter members 22 which are arrange | positioned two steps up and down upstream with respect to the insertion direction of the to-be-cut object of the insertion path 13, respectively. The two third cutter members 23, the fourth cutter member 24, and the fifth cutter member 25 that are arranged in three stages on the downstream side with respect to the insertion direction of the workpiece are pressed against each other in the lateral (horizontal) direction. Because of this, it is the thickness from the large-diameter radish R to the small-diameter burdock, and of course it can peel the entire peripheral surface from the front end to the rear end, such as potato, taro etc. Since the lump vegetables can also be peeled, a very versatile skinning device can be provided.

  As described above, according to the present embodiment, the first cutter member 21 and the second cutter member 22 arranged on the upstream side with respect to the insertion direction of the workpiece in the insertion passage 13 are radially arranged. Since a gap is formed inside the first cutter member 21 and the second cutter member 22 that are radially arranged, the work piece is pushed into the insertion path 13 by the push rod 77 of the push mechanism 70. The tip of the push rod 77 does not interfere with the first cutter member 21 and the second cutter member 22. Thereby, since the front-end | tip of the push rod 77 is reliably guided to the space | gap part formed inside the 1st cutter member 21 and the 2nd cutter member 22, it can peel a to-be-cut object reliably and smoothly. it can.

  Here, when all three of the cutter members 20 arranged in multiple stages are arranged radially, the length of the push rod 77 of the pressing mechanism 70 is set to a length that can pass through all of the cutter members 20. When the workpiece is pushed into the insertion path 13 by the push rod 77, the tip of the push rod 77 does not interfere with each cutter member 20. However, in this case, since the three stages of the cutter member 20 are arranged radially, in addition to the tip of the radish R and the small diameter burdock, it is possible to peel lumps of vegetables such as potatoes and taros. become unable.

  Therefore, in the present embodiment, as described above, the first cutter member 21 and the second cutter member 22 that are arranged in two upper and lower stages on the upstream side with respect to the insertion direction of the workpiece in the insertion passage 13 are each radially 3. The two third cutter members 23, the fourth cutter member 24, and the fifth cutter member 25, which are arranged in three upper and lower stages on the downstream side with respect to the insertion direction of the workpiece, are arranged in the lateral (horizontal) direction. Are in pressure contact with each other.

  Moreover, according to this embodiment, since the to-be-cut object was pushed into the insertion path 13 by the press mechanism 70, the cutting efficiency of the to-be-cut object can be improved significantly.

  Furthermore, according to the present embodiment, of the first to fifth cutter members 21 to 25 arranged in multiple stages in the longitudinal direction of the insertion path 13, the downstream side with respect to the insertion direction of the workpiece in the insertion path 13. Since the third cutter member 23, the fourth cutter member 24, and the fifth cutter member 25 arranged in the two are arranged in contact with each other in the lateral direction, even a small-diameter workpiece such as a burdock can be peeled off. In addition, the front end and the rear end in the insertion direction of the workpiece can be reliably peeled off.

  And according to this embodiment, since the cutter unit 10 is being fixed to the lower circular hole board 16 in which the opening part 16a used as the insertion path 13 for inserting a to-be-cut object is formed, the cutter member 20 Are fixed to the lower circular hole plate 16, the cutter unit 10 is not provided in a plurality of stages, and the insertion path 13 can be shortened. As a result, even if the workpiece is slightly bent, it can be reliably peeled off and the apparatus can be downsized.

  Moreover, according to this embodiment, the 1st cutter by which the lower end was arrange | positioned toward the longitudinal direction center of the insertion path 13 in the upper circular plate 15 and the lower circular plate 16, respectively, and the lower end was arrange | positioned in the upstream of the insertion path 13 The upper guide springs 18 and the lower guide springs 19 are fixed in a vertically downward direction so as to face the member 21, and the workpieces are reliably secured in the longitudinal center direction of the insertion passage 13 by fixing the upper guide springs 18 and the lower guide springs 19. Can be guided to.

  Furthermore, according to this embodiment, since the pressing mechanism 70 is installed on the support base 2, operability can be improved. Further, by forming a discharge port communicating with the insertion passage 13 in the support base 2 and discharging the workpiece to which the skin has been peeled from the discharge port, the workpiece to be peeled can be smoothly discharged. Can do.

  According to the present embodiment, the pressing mechanism 70 includes the push rod 77 that presses the workpiece, and the support arm 60 including the guide hole 62 a that guides the push rod 77 to the insertion path 13 is the support base 2. Since it is installed on the top, the tip of the push rod 77 can be reliably guided to the gap formed inside the cutter member 20, and the workpiece can always be peeled off reliably and smoothly. .

  In addition, according to the present embodiment, the plurality of cutter members 20 have the arm portion 32 formed in a U-shaped cross section, while the pressing spring 50 is formed in a U-shaped cross section and the arm portion 32 is fitted therein. By having the portion 56, the plurality of cutter members 20 can always be urged toward the center in the longitudinal direction of the insertion passage 13 without the plurality of cutter members 20 swinging left and right. As a result, uncut portions of the workpiece can be prevented and the skin can be reliably peeled over the entire circumferential direction of the workpiece.

  Here, when the plurality of cutter members 20 and the pressing springs 50 are fixed by clip-shaped fixing brackets, the plurality of cutter members 20 It becomes impossible to smoothly urge the insertion passage 13 with respect to the central direction in the vertical direction.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, in the above embodiment, the pressing mechanism 70 is configured such that the operator grips and pushes down the handle 78. However, the pressing mechanism 70 is not limited to this and is driven by driving means such as fluid pressure or an electric motor. Also good.

  Moreover, although the said embodiment demonstrated the example which each arrange | positioned the 1st cutter member 21 and the 2nd cutter member 22 radially, 4 or more may be sufficient, and what is necessary is just to arrange | position at least 3 in short.
