Description

  The present invention relates to a peeling apparatus for various other agricultural products such as potato, taro, kiwi fruit and avocado.

  Conventionally, peeling of various agricultural products such as potatoes has been mainly performed manually with a knife or peeler (see, for example, Patent Document 1), but various peeling devices that automatically peel are proposed. Has been.

  For example, the peeling apparatus described in Patent Document 2 is provided with an opening that can be opened and closed on the peripheral surface of a cylindrical drum in which punching holes are formed. A large number of potatoes and the like are introduced into the drum through the inlet, and the inlet is closed and the drum is rotated around the cylinder axis so that peeling can be performed (see, for example, Patent Document 2).

  Moreover, the peeling apparatus described in Patent Document 3 has two cylindrical drums provided with a large number of punching holes on the peripheral surface thereof in parallel, and these drums rotate upward at their opposing portions. In addition, both the drums are rotated.

  Due to the rotation of both drums, the surface of the object to be peeled is cut at the surface layer by punching holes provided on the peripheral surfaces of both drums.

  In addition, since both drums are disposed so as to incline downward from the input position at one end in the cylinder axis direction toward the discharge port at the other end, the objects are automatically peeled in the order in which they are input. (Refer to Patent Document 3, for example).

Moreover, the peeling apparatus of patent document 4 makes it possible to adjust the downward inclination angle of two cylindrical drums, and controls a conveyance speed according to the state and kind of a target object (for example, patent document) 4).

  Furthermore, the peeling apparatus described in Patent Document 5 includes two cylindrical drums having punching holes, as in Patent Documents 3 and 4, and is provided on a conveyance path formed in a portion sandwiched between the two drums. The objects to be peeled, such as potatoes, are sequentially supplied by a predetermined amount by an alignment supply device provided separately. By rotating both drums, the surface of the object is cut by punching holes provided on the peripheral surfaces of both drums. In addition, the peeled object is moved from the start side to the end side of the conveyance path by the pressing plate (see, for example, Patent Document 5).

JP-A-11-221148 JP 2002-253190 A Utility Model Registration No. 3084921 JP 2009-171941 A Japanese Patent No. 4247923

  The peeling apparatus described in the above-mentioned Patent Document 2 is a method in which an object to be peeled, such as potatoes, is input and peeled by a predetermined amount, but in order to take out the peeled object, It is necessary to put in hand. Such manual removal of the object is inefficient and dangerous because the device may move while the hand is in the drum.

  In this regard, the peeling device described in Patent Documents 3, 4 and 5 has two drums having a large number of punching holes on the peripheral surface thereof arranged in parallel, and the object on the two drums is arranged in parallel. Since the skin is peeled off, it is not necessary to put a hand in the drum to take the object, and the object can be taken out easily and safely.

  However, in this peeling device, some of the scraps such as peeled skin fall down below the drum, but many scraps pass through the punching holes and enter the cylindrical drum. There is a problem of entering.

  That is, since the drum must be rotatably supported by the frame of the apparatus, it is necessary that the rotating shaft protrude from both ends of the drum. In order to provide the protruding rotating shaft, both ends of the drum are closed by a lid (supporting member) as shown in FIG. 16, and the rotating shaft projects from the lid.

  For this reason, when taking out internal waste, it is necessary to remove the cover body which closes the end surface of the drum with a rotating shaft. Such an attaching / detaching operation is troublesome.

  Accordingly, an object of the present invention is to make it possible to easily take out scraped scraps remaining in a rotating body in a peeling apparatus using a pair of rotating bodies such as cylindrical drums. .

  In order to solve the above-mentioned problems, the present invention arranges two rotating bodies having a cylindrical shape in parallel, and at least one of the rotating bodies has a plurality of inner and outer penetrating side members around the cylinder axis. It is provided with cutting holes, and is supported rotatably around the cylinder axis with respect to the frame by rotation shafts provided at both ends of the cylinder axis direction, and an object to be peeled is placed on the pair of rotating bodies. By rotating the rotating body around the cylinder axis, the surface layer portion of the object is scraped at the edge of the cutting hole, and the rotating body provided with the cutting hole includes the rotating shaft and the side surface. A member is supported by a support member that extends from the side surface member toward a direction approaching the cylinder axis, and the scraped portion in the side surface member is scraped at one or both ends of the cylinder axis direction. Peeling characterized by comprising an opening that can discharge the surface layer It was the location of the configuration.

  According to this configuration, it is possible to discharge the peeled scrap, that is, the shaved surface layer portion, through the opening provided at the end portion in the cylinder axis direction of the rotating body. For this reason, unlike the conventional case, it is not necessary to open and close the lid that closes the end of the rotating body, and the scraped scrap can be easily taken out.

  In addition, this opening part may be provided in the edge part of either side of the cylinder axis direction of a rotary body, and may be provided in the edge part of both cylinder axis directions. Moreover, the shape, position, and quantity of the opening are free. For example, it may be a circular opening or an opening having various shapes such as a rectangle or a fan shape. Moreover, it may be one place around the rotation axis, or two places or three or more places.

  Further, the support member for connecting the rotation shaft and the side member may extend from the end of the side member in the cylinder axis direction toward the rotation axis, or enter the inner side in the tube axis direction from the end of the cylinder axis. You may extend toward a rotating shaft from a position.

In each of these configurations, the support member is formed by arranging a plurality of radial members that connect the cylindrical shaft end edge of the side member and the rotation shaft around the cylindrical shaft, and in the circumferential direction. It is possible to employ a configuration in which the opening is formed between adjacent radial members.
That is, a plurality of radial members extending radially outward from the rotating shaft are arranged, and the radial members are fixed by connecting the rotating shaft and the side members radially like a spoke of a wheel. It is a configuration. At this time, the scraped surface layer portion can be discharged from between the adjacent radial members and the opening between the adjacent radial members.

  In addition, as a fixing structure to the frame of the rotary body used for such a peeling apparatus, for example, the following structure is used, so that the apparatus can be easily attached to and detached from the frame.

  That is, the configuration that facilitates the attachment and detachment, for example, the rotating body, the rotating shaft on either side of the cylindrical axis direction is coaxially connected to the driving shaft that is rotated by the driving force from the driving source, With this connection, rotation is transmitted from the drive shaft to the rotary shaft, and the end of the rotary shaft opposite to the drive shaft side is connected to the frame. The connection between the rotary shaft and the drive shaft is released in a state before being supported by the drive shaft, and the connection to the frame at the end of the rotary shaft opposite to the drive shaft is released. It is.

According to this configuration, the driving force transmission mechanism and the rotating shaft of the rotating body can be easily disconnected and connected. The rotating shaft of the rotating body and the driving shaft can be separated without disassembling a complicated driving force transmission mechanism using a belt, a gear or the like.
It is possible to take out scrapped scraps with the rotating body attached to the frame, but if the rotating body can be easily attached to and detached from the frame, remove the rotating body at an appropriate time and tilt or shake it. This makes it easier to remove the scraps that have been peeled off.

  According to the present invention, in a peeling apparatus using a pair of rotating bodies made of a cylindrical drum or the like, scraped scraps remaining in the rotating body can be easily taken out.

  Embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3, the peeling device M of this embodiment includes a main body frame F of a left frame 1, a right frame 2, a side frame 3, a side frame 4, guide members 5, 6, and The frame member 8 or the like provided on the upper part thereof.

  Two drum-like rotating bodies (cylindrical rotating blades) 20 and 21 are supported in parallel on the main body frame F. In this embodiment, each rotary body 20 and 21 is cylindrical, and is provided with a plurality of cutting holes 20c and 21c penetrating inward and outward in side members 20a and 21a forming a side peripheral surface around the cylinder axis. .

  In this embodiment, as the material of the side members 20a and 21a, a punched metal having a large number of holes is bent and formed into a cylindrical shape, but is not limited to this material, and can be formed into a cylindrical shape. A material other than punching metal may be used as long as the material has a plurality of holes penetrating the cylinder in and out.

  Each of the rotating bodies 20 and 21 is supported by the main body frame F so as to be rotatable around the cylinder axis by a rotation shaft 27 provided so as to protrude from both ends in the cylinder axis direction.

  The axis of the rotary shaft 27 coincides with the axis of the side members 20a and 21a, and the side members 20a and 21a and the rotary shaft 27 are supported and integrated by the support member 26.

  The support member 26 is joined to the cylinder axis direction edges 20b and 21b of the side members 20a and 21a, extends from the side member 20 in the direction approaching the cylinder axis, and is joined to the outer peripheral surface of the rotary shaft 27.

Moreover, each rotary body 20 and 21 is provided with the opening part 26a which can discharge | emit the peeling waste which penetrated into the side surface members 20a and 21a in the edge part of both the cylinder axial directions.
As will be described later, the peeled scrap is a case where a peeled object P is placed on a pair of rotating bodies 20 and 21 and the pair of rotating bodies 20 and 21 is rotated around a cylinder axis. Further, a surface layer portion such as a skin of the object P cut at the edge of the cutting holes 20c and 21c.

In this embodiment, as shown in FIG. 4, the support member 26 includes a plurality of radial members 26b that connect the cylindrical shaft edges 20d, 21d of the side members 20a, 21a and the rotary shaft 27 around the cylindrical shaft. The book is arranged. In this embodiment, the four radial members 26b are arranged radially so as to be equally divided.
For this reason, between the radial members 26b and 26b adjacent to each other in the circumferential direction among the plurality of radial members 26b is an opening 26a. There are four openings 26 a along the circumferential direction around the rotation shaft 27.

  On the pair of rotating bodies 20 and 21, a work space capable of accommodating the agricultural product as the peeled object P is provided. As shown in FIGS. 1 to 3, the work space is partitioned on the inside and outside by a guide chute (guide member) 9 that is a frame-like member that is open at the top and bottom.

As shown in FIGS. 1 and 2, the guide chute 9 includes a pair of inclined plates 9a and 9b that gradually approach each other at both ends in the width direction.
Further, along the axial direction of the rotating shaft 27 of each rotating body 20, 21, an opening 9e provided with a chute capable of discharging the object P out of the work space is provided on one end side in the axial direction. . Further, the other end face in the axial direction is closed by an end face plate 9f.

The lower surface of the guide chute 9 is opened, and the lower end edges of the pair of inclined plates 9a and 9b, the other end side edge of the open portion 9e, and the arcuate lower end edge of the end face plate 9f are respectively rotating bodies 20 and 21. It faces through a slight gap.
For this reason, the work space inside the guide chute 9 is opened toward the pair of rotating bodies 20 and 21, and the object P accommodated in the work space is prevented from spilling outside. Reference numeral 9h in the drawing is a notch for the rotary shaft 27 to enter.

  In addition, since the two rotary bodies 20 and 21 are arrange | positioned in parallel through the predetermined clearance gap, the agricultural product which is the target object P to peel does not fall from the clearance gap.

  Then, a part of the scrap generated by peeling falls downward through a gap between the rotating bodies 20 and 21 and a slight gap between the edge of the guide chute 9 and the rotating bodies 20 and 21 described above. . The fallen waste is guided to a predetermined position by the guide members 5 and 6.

  Further, a part of the scrap generated by peeling passes through the cutting holes 20c and 21c of the respective rotary bodies 20 and 21 and enters the side members 20a and 21a, that is, into the rotary bodies 20 and 21. It gradually accumulates.

  The opening 9e of the work space is closed by a detachable restriction plate 22. If the restriction plate 22 is attached from the state shown in FIG. 2 to the state shown in FIG. 1, the work space is closed, so that the object P is not discharged out of the work space. If the restricting plate 22 is removed, the object P can be discharged laterally toward one end in the axial direction.

  In this embodiment, the restriction plate 22 is attached and detached by fitting the engagement holes H1 and H2 provided in the guide chute 9 and the protrusions J1 and J2 provided in the restriction plate 22.

The main body frame F has a left frame 1 whose upper center is opened upward, and a guide chute 9 is disposed on the open portion of the left frame 1 and the frame member 8 provided on the upper portion of the main body frame F. It is supposed to be placed. It is also possible to provide means for fixing the guide chute 9 and the main body frame F so as not to move.
For this reason, as shown in FIG. 2, the guide chute 9 can be lifted upward and easily removed.

  The rotators 20 and 21 are configured to rotate around the axis of each rotating shaft 27 by the driving force of the motors 10 and 11 as driving means.

  That is, as shown in FIGS. 3B and 3C, each of the rotating bodies 20 and 21 is supplied by the motor 10 via the belt 13 and the rotor 14, or by the motor 11, the rotor 15, the belt 16, and the rotor 17. The rotation transmitted to the drive shaft 23 is transmitted to the rotation shaft 27 connected to the drive shaft 23, so that the rotation about the axis is possible.

  Both motors 10 and 11 can freely change the number of rotations in a stepless manner, and both can rotate forward and backward. Therefore, the rotating bodies 20 and 21 can follow the motors 10 and 11 to freely change the rotational speed and the forward and reverse rotations.

  As shown in FIG. 6, the rotating shaft 27 of each rotating body 20, 21 is rotatably supported on the frame 7 of the main body frame via a bearing portion 31 as shown in FIG. 6.

  As shown in FIG. 6, one end of the rotating shaft 27 in the axial direction of the bearing portion 31 is held by a cylindrical casing 31 a via a seal 28 and a bearing 29, and the casing 31 a is provided on the frame 1. In a state of being sandwiched between the bearing holder lower 32 and the bearing holder upper 34, the bearing holder lower 32 and the bearing holder upper 34 are fixed by tightening with the fixing means 33 as shown in FIGS. To do.

  Cylindrical surfaces 32a and 32b; 34a and 34b with which the casing 31a can come into surface contact are formed on the lower bearing holder 32 and the upper bearing holder 34, respectively. Reference numerals 32c and 32d in the figure are key grooves into which a key (not shown) provided in the casing 31a enters, and prevents the casing 31a itself of the bearing portion 31 from rotating.

  Further, as shown in FIG. 6, the other axial end of the rotating shaft 27 of each rotating body 20, 21 is elastically coupled to a drive shaft 23 that is rotatably supported by the main body frame F via a bearing portion 18. Connected through. In this embodiment, the elastic body 25 is made of rubber, but may be an elastic body made of another structure using a spring or the like as a component.

  That is, one end (end on the rotating body side) 23a in the axial direction of the drive shaft 23 has a square cross section, and the storage portion of the elastic body 25 into which the drive shaft 23 is inserted has a square cross section. Further, at the other end in the axial direction of each of the rotating bodies 20 and 21, a storage portion (concave portion) of the elastic body 25 is provided on the end face of the rotating shaft 27 in a square cross section. An elastic body 25 can be fitted in the storage portion.

The shaft end (convex portion) of the drive shaft 23 is fitted into the storage portion on the end surface of the rotation shaft 27 via the elastic body 25 so that the rotation of the drive shaft 23 can be transmitted to the rotation bodies 20 and 21. It has become. When the drive shaft 23 is fitted into the storage portion via the elastic body 25, it is preferable to allow the drive shaft 23 to be fitted in a press-fitted state because the rattling of the connecting portion is reduced.
The nut 23c is screwed into a screw portion 23b provided at the other axial end of the drive shaft 23, so that the drive shaft 23 and the rotors 12 and 17 can rotate integrally.
Further, in a state before the drive shaft 23 and the rotary shaft 27 are connected, the elastic body 25 may be attached to the axial end 23 a side of the drive shaft 23, or attached to the storage portion of the support member 26. It may be. The same applies to the state after the connection is disconnected.

  Thus, by interposing the elastic body 25 between the drive shaft 23 and the rotating bodies 20 and 21 (rotating shaft 27), the main body frame F is distorted due to welding distortion or the like, and the frames 1 and 2 Even if the axial centers of the places where the rotary bodies 20 and 21 are placed are slightly deviated from each other, the error can be absorbed by the deformation of the elastic body 25.

  For this reason, even if there is distortion or the like in the main body frame F, the rotating bodies 20 and 21 can be installed without any problem. That is, even if the main body frame F is distorted or the like and the core accuracy of the bearing tube is slightly deviated, the peeling process of the object P by the rotating bodies 20 and 21 is performed without applying excessive force (load) to the machine. Does not impede performance.

Further, since the elastic body 25 absorbs vibrations generated when the rotating bodies 20 and 21 rotate, the sound is quiet. Furthermore, by providing the elastic body 25, the rotary bodies 20 and 21 can be easily inserted into and removed from the drive shaft 23. This is because the conventional structure has a problem that if the core accuracy is slightly deviated, it is difficult to remove the rotating body after use.
In addition, there exists an advantage that attachment / detachment of this rotary body 20 and 21 can be performed without a tool.

  If the effect of the elastic body 25 is not desired, the elastic body 25 can be omitted. When the elastic body 25 is not interposed, the shaft end portion (convex portion) of the drive shaft 23 without the elastic body 25 being interposed in the rotating shaft 27 of the rotating bodies 20 and 21 or the housing portion (concave portion) of the support member 26. It is sufficient that the rotation of the drive shaft 23 can be transmitted to each of the rotating bodies 20 and 21 by being fitted. Also in this configuration, when the drive shaft 23 is fitted into the storage portion, it is preferable to allow the drive shaft 23 to be fitted in a press-fitted state because the rattling of the connecting portion is reduced.

As described above, one axial end of the rotating shaft 27 of each of the rotating bodies 20 and 21 can be fixed to the main body frame by the fixing means 33 and the fixing can be released, and the other axial end of the rotating shaft 27 is Since connection to and disconnection from the drive shaft 23 is possible, for example, after the other axial end of the rotary shaft 27 is connected to the drive shaft 23, one end in the axial direction of the rotary shaft 27 is connected to the main body frame by the fixing means 33. By fixing, each rotary body 20 and 21 can be attached easily.
In addition, after releasing the fixing by the fixing means 33, if the connection between the other axial end of the rotating shaft 27 and the drive shaft 23 is disconnected, the rotating bodies 20 and 21 can be easily removed. That is, cleaning and replacement of the rotating bodies 20 and 21 can be performed very easily.

  In this embodiment, the configuration in which the rotary bodies 20 and 21 are detachably attached to the main body frame, or the above-described fixing structure or the configuration in which the elastic body 25 is interposed is used for the attachment / detachment. In addition to the rotating bodies 20 and 21 provided with the cutting holes on the peripheral surface of the cylindrical member shown, for example, a cylindrical rotating body having a polygonal shape such as a hexagonal cross section or an octagonal cross section may be used.

  The operation of the peeling apparatus M will be described. By rotating the rotary bodies 20 and 21 around the axis of the rotary shaft 27 by the driving force of the motors 10 and 11, respectively, the surface layer of the object P in the work space. The part is cut by the edges of the cutting holes 20c and 21c which are cutting means.

  In this embodiment, the cutting holes 20 c, 21 c of the rotating bodies 20, 21 are long holes that extend obliquely with respect to the axial direction of the rotating shaft 27.

  As shown in FIG. 8A, the direction in which the elongated hole extends is such that one of the rotating bodies 20 is directed from one axial end (discharge side) to the other axial end in plan view from above the work space. Accordingly, the direction gradually moves away from the other rotating body 21. In this embodiment, all the cutting holes 20c are configured with the same shape, size, and orientation.

  Similarly, as shown in FIG. 8A, the other rotating body 21 gradually increases from the one axial end side (discharge side) toward the other axial end in a plan view from above the work space. The direction approaches one rotating body 21. In this embodiment, all the cutting holes 21c are configured with the same shape, size, and orientation.

  Next, the operation of the cutting holes 20c and 21c of the rotating bodies 20 and 21 will be described.

  When peeling the object P, as shown in FIGS. 8A and 8B, the rotary bodies 20 and 21 are rotated in the R1 and R2 directions from the inside toward the outside on the upper surface side. In this state, the surface of the object P accommodated in the work space is cut at the edges of the cutting holes 20c and 21c, and is peeled off.

At this time, in one rotating body 20, the surface layer is cut by the blade line (edge on the other end side in the axial direction) L1 of the cutting hole 20c, and the object P has a thrust (axial direction) in the direction indicated by G1 in the drawing. The object P whose surface layer is scraped by the blade line (edge on one end side in the axial direction) L2 of the cutting hole 21c in the other rotating body 21 is indicated by G2 in the figure. A thrust in the direction shown (force pushed toward the other end in the axial direction) is generated.
For this reason, the thrusts indicated by G1 and G2 cancel each other, and the object P can be peeled efficiently in a balanced manner without being pushed toward one side in the axial direction.

  Further, the object P rotates moderately (rotates) by the thrust in the opposite direction indicated by G1 and G2, so that only the specific part of the outer surface of the object P is not shaved, and the outer surface covers the entire surface. Can be cut evenly.

Further, when the object P is discharged after finishing the peeling, for example, as shown in FIGS. 8C and 8D, one side of the rotating body, for example, the other rotating body 21 is moved like R3. When the direction of rotation is reversed from the outside to the inside, the thrust in the direction indicated by G3 in the drawing (to one end side in the axial direction) is applied to the object P by the cutting resistance of the blade line (edge on the other end side in the axial direction) L3. Pressed force) is applied.
For this reason, the thrust in the G1 direction by one rotating body 20 and the thrust in the G3 direction by the other rotating body 21 are both in the same direction, and the object P is automatically moved toward the discharge-side opening 9e. Can be discharged.

As described above, the cutting holes 20a and 21a of the rotary bodies 20 and 21 are long holes extending obliquely with respect to the axial direction of the rotary shaft 27. The edge on either side in the axial direction functions as a thrust applying means for the object P.
In other words, the thrust applying means for applying the thrust in the axial direction to the object P is configured by arranging the edges of the cutting holes 20a and 21a obliquely with respect to the axial direction of the rotary shaft 27. is there.

  The thrust applying means has a function of pressing the object P in the axial direction when it hits the object P along with the rotation of the rotating bodies 20 and 21, so that the edge of the cutting holes 20 c and 21 c faces the oblique direction. It is efficient that the direction is a direction that gradually approaches the upstream side in the rotational direction (going in the direction opposite to the rotational direction) as it goes in the direction in which the object P is to be pressed. Therefore, if it has such a function, the shape of the cutting holes 20c and 21c is not limited to a long hole. A configuration in which the edge of the cutting holes 20c and 21c is arranged in an oblique direction with respect to the axial direction of the rotating shaft 27 so that thrust in the axial direction is applied to the object P by the rotation of the rotating bodies 20 and 21. If so, the shapes of the cutting holes 20c and 21c can be, for example, square or hexagonal.

  As described above, by providing the thrust applying means to the rotating bodies 20 and 21, the object P can be easily discharged without adding a special discharge pressing plate or the like to the peeling device, and a complicated mechanism is provided. Therefore, maintenance is easy, and the apparatus can be made inexpensive and with few failures.

  The installation of the thrust applying means is arbitrary, and can be omitted if unnecessary. In that case, the shape of the cutting holes 20c and 21c can be, for example, a circular cross section (perfect circle). In other words, if the cutting holes 20c and 21c are symmetrical with respect to the axis of symmetry orthogonal to the axial direction, it can be set so that axial thrust is not generated even if the rotating body rotates in any direction around the axis.

  Moreover, you may provide a thrust provision means only in one side among a pair of rotary bodies 20 and 21. FIG. That is, the oblong oblong cutting holes 20a and 20b constituting the thrust applying means are provided only on one side of the pair of rotating bodies 20 and 21, for example, only on one rotating body 20 and on the other rotating body 21. May be provided with a cutting hole 21c that does not generate axial thrust, such as a circle or a hexagon.

As described above, when the thrust applying means is provided only on one rotating body 21, the thrust acting on the object P is reduced. For example, the axial direction when the object P is discharged out of the work space. The speed of movement to is slightly slower.
However, on the other hand, during peeling, there is a case where the target P is not excessively pushed to the discharge side, but rather can be peeled off without problems.

  Furthermore, another embodiment is shown in FIG. 9 regarding the attachment / detachment structure of each rotary body 20,21. In this embodiment, the other end in the axial direction of the shaft 36 that is rotatably supported by the bearing portion 31 (the end portion on the rotating body 20, 21 side) is convex, and the axis of the rotating shaft 27 of each rotating body 20, 21. One end in the direction is concave, and the shaft 36 and the rotary shaft 27 can be connected or disconnected. In this embodiment, one axial end of the shaft 36 has a frustum-shaped convex shape, and one axial end of the rotary shaft 27 has a corresponding frustum-shaped concave shape. Can be mated.

  Similar to the above-described embodiment, the bearing portion 31 includes the seal 28 and the bearing 29, and the shaft 36 is rotatable with respect to the casing 31a.

  The bearing part 31 is movable in the axial direction when connected to the rotary shaft 27 of each rotary body 20, 21. When the rotary bodies 20, 21 are mounted, the bearing part 31 is moved to the rotary body 20, 21. The shaft 36 is engaged with the rotating shaft 27 by being advanced in the 21 direction (see FIG. 9B). If the nut 30 is tightened, the axial movement of the bearing portion 31 is restricted.

  Thus, the attachment / detachment structure of the rotating bodies 20 and 21 is not limited to the embodiment, and various configurations can be adopted.

  When discharging the peeled debris that has entered the rotary bodies 20 and 21, the peeled debris, that is, the cutting scraps, is provided through the openings 26 a provided at the ends of the rotary bodies 20 and 21 in the cylinder axis direction. The surface layer is discharged to the outside. Since the opening 26a is provided, the peeled waste can be easily taken out as it is.

  At this time, if each of the rotating bodies 20 and 21 is removed from the main body frame F, the operation is further simplified. That is, since the rotators 20 and 21 can be easily attached to and detached from the main body frame F, the rotators 20 and 21 can be easily detached, tilted or shaken, and the peeled waste can be brought close to the opening 26a. . For this reason, it is easier to remove the waste.

  In addition, the opening part 26a of the rotary bodies 20 and 21 may be provided only in the edge part of the cylinder axis direction one side of the rotary bodies 20 and 21 like this embodiment, and both cylinder axis directions may be provided. It may be provided at the end portion. If the opening 26a is provided at both ends in the cylinder axis direction, it is convenient that waste can be discharged from the opening 26a on either side.

  Further, the shape, position and quantity of the opening 26a are free. For example, as shown in FIG. 10A, the number of openings 26 a may be two around the axis of the rotation shaft 27. At this time, the radially extending radial members 26b constituting the support member 26 are two.

  In addition, if the number of radial members 26b constituting the support member 26 is increased or decreased, the number of openings 26a can be increased or decreased. For example, if the number of radially extending radial members 26b is three around the axis of the rotary shaft 27, the number of openings 26a is also three.

  Further, without using the radial member 26b as the support member 26, an annular (doughnut-shaped) plate material that closes the cylindrical axial ends of the rotating bodies 20 and 21 is fixed to form the support member 26. It is also possible to adopt a configuration in which an appropriate number of openings 26a penetrating through are provided.

Further, as shown in FIG. 10 (b), the support member 26 for connecting the rotary shaft 27 and the side members 20a, 21a is connected to the inner side in the cylindrical axis direction from the cylindrical axial edges 20b, 21b of the side members 20a, 21a. You may make it extend toward the rotating shaft 27 from the position which entered.
At this time, the opening 26a is formed between the outer periphery of the rotation shaft 27 and the cylinder axis direction edges 20b and 21b of the side members 20a and 21a over the entire circumference around the axis of the rotation shaft 27.
