FIG. 6 is a perspective view showing the locking arm 100 for restricting the rotation of the lever 90 and its mounting structure. A mounting plate 111, which is a rectangular plate-like member, is attached to a corner portion of the horizontal portion 55a (FIG. 3) of the support plate 55 (FIG. 3) near the vertical portion 55b (FIG. 3). The mounting plate 111 has a bent upper end, and the upper end is fixed to the lower surface of the horizontal portion 55a. One surface of the mounting plate 111 is substantially the rotation axis C.
It is arranged so that it may face. A mounting piece 112 having a shape obtained by bending a rectangular plate-like member is mounted on a surface of the mounting plate 111 on the rotation axis C side. Mounting piece 11
One of the two bent portions is fixed to a surface of the mounting plate 111 facing the rotation axis C, and the other portion extends horizontally toward the rotation axis C.

The engaging pin 102 is engaged with the locking pin 102. The notch 117 has surfaces 117a and 117b with which the locking pin 102 comes into contact when rotating about the rotation axis C. However, when the locking pin 102 moves straight toward the rotation axis C, the notch 117 has a notch. There is no contact surface. That is, the locking arm 1
10 restricts only the rotation of the lever 90,
The movement in the direction toward the zero rotation axis C is not restricted. Here, the locking arm 110 corresponds to one specific example of “rotation restricting means” and one specific example of “stopper” in the present invention.

In the horizontal portion 55a of the support plate 55, a lever 9 is provided at a corner portion opposite to the locking arm 110.
A stopper pin 118 for locking the rotation of 0 is formed so as to protrude vertically downward. When the lever 90 rotates about 180 degrees from the initial rotation position, the stopper pin 118
The lever 90 comes into contact with the horizontal portion 90a. The position where the lever 90 contacts the stopper pin 118 is the rotation end position of the lever 90. Here, the stopper pin 118 corresponds to one specific example of “rotation restricting means” and one specific example of “stopper” in the present invention.

As shown in FIG. 4, a rotation initial position sensor 61 for detecting whether or not the lever 90 is at the rotation initial position is provided near the locking arm 110. The rotation initial position sensor 61 has a light-emitting element and a light-receiving element (not shown) arranged opposite to each other. When the lever 90 reaches the initial rotation position, the shutter plate 99 mounted on the upper surface of the lever 90 enters between the light emitting element and the light receiving element of the initial rotation position sensor 61. When the light receiving element stops detecting light, the rotation initial position sensor 61 issues a rotation initial position signal, whereby the sequencer 77 determines that the lever 90 has reached the rotation initial position. Similarly, as shown in FIG.
Is provided with an end point position sensor 62 for detecting whether or not the lever 90 is at the rotation end point position. The rotation end position sensor 62 is configured in the same manner as the rotation initial position sensor, detects the shutter plate 99 of the lever 90, and issues a rotation end position signal, whereby the control unit described later moves the lever 90 to the rotation initial position. Is determined to have been reached. In FIG. 3, the rotation initial position sensor 61 and the rotation end point position sensor 62 are both shown as rectangular parallelepiped blocks.

An outermost position sensor 64 for detecting whether or not the slider 100 is farthest from the rotation axis C is provided near the stopper pin 118. The outermost position sensor 64 has a light emitting element and a light receiving element (not shown) arranged opposite to each other. When the slider 100 reaches the position farthest from the rotation axis C, the shutter plate 103 of the slider 100 enters between the light emitting element and the light receiving element of the outermost position sensor 64. The outermost position sensor 64 emits an outermost position signal when the light receiving element stops receiving light, whereby the sequencer 77
Determines that the slider 100 has reached the outermost position.

As shown in FIG. 1, an air pipe 74 is provided on the second top plate 4 of the main body. The nozzle 75 connected to the air pipe 74 is directed to the peeling blade 73. The air pipe 74 is connected to an unillustrated air pressure source via an on / off valve 76. Here, by spraying air from the nozzle 75 to the skin stripping blade 73, it is possible to blow off the skin and the like attached to the blade of the skin stripping blade 73.

The partition plate 6 of the main body of the peeling machine 1 is provided with a take-in tray (not shown) which can move forward and backward.
The tray moves to a position directly below the persimmon adsorbed on the suction pad 54 and receives the persimmon whose skin has been peeled off.
Is to be dropped. A detailed description of this tray will be omitted.

The sequencer 77 provided on the main body of the peeling machine 1 includes an outermost position sensor 64, a rotational position sensor 61,
62 and a detection signal from the pressure sensor 53, the fruit vegetable rotation motor 48, the peeling blade drive motor 57,
An operation signal is output to the off valve 76 and the like.

[Operation of Peeling Machine 1] Next, the operation of the peeling machine 1 of the present embodiment will be described.

When cutting the cut portion Pa of the persimmon P using the cutout device 1A, the operator first turns the cut portion Pa of the persimmon P downward, and cuts the hard portion K around the branch E. It hits the pin 44 in the guide 15. Next, the worker
When the persimmon P is pushed vertically downward against the spring force of the compression spring 16b, the rod 40 moves downward, and the guide 15 is urged by the outer peripheral surface of the persimmon P to cause the annular support 14 to move.
Slide toward. At this time, since the contact member 41 of the rod 40 moves downward, the lever 38a of the limit switch 38 swings, whereby the limit switch 38
Sends a detection signal to the sequencer 77. PLC 77
Operates the cutting blade drive motor 17 based on this detection signal. The rotational force of the cutting blade drive motor 17 is reduced via the gear box 22 and transmitted to the output shaft 23, and then the drive pulley 24, the belt 27 and the driven pulley 2
6 to the drive shaft 25. As a result, the drive shaft 25 rotates and the cutting blade 30 rotates, and cuts off the cut portion Pa of the persimmon P. Note that the downward movement of the rod 40 is limited by the contact member 41 abutting the lower limit stopper 37. For this reason, the cut surface of the persimmon P formed by the rotation of the cutting blade 30 has a concave portion Pa of the persimmon P.
Is formed so as to be a substantially rotational surface centered on a straight line connecting the approximate center and the top. The thickness of the persimmon P can be adjusted by changing the vertical position of the lower limit stopper 37.

After cutting off the paved portion Pa with the cleaving device 1A, the operator lifts the persimmon P, and the rod 40
Is moved upward by the elastic force of the coil spring 42, and the contact member 41 swings the lever 38a of the limit switch 38. As a result, a detection signal is sent from the limit switch 38 to the sequencer 77. The sequencer 77 stops the rotation of the cutting blade drive motor 17 based on the detection signal. Next, the sequencer 77 operates the on / off valve 4
7 is turned on. When the on / off valve 47 is turned on, air from the air pressure source is supplied to the nozzle 46.
Blade 30, disk 28 and bracket 2 through
It is injected intermittently toward 9. Thereby, the cutting blade 3
0, the persimmons of the persimmon P accumulated on the disc 28 and the bracket 29 are blown away, and the operator does not need to remove the perfumes. As described above, since the guide 15 slides when the operator touches the persimmon P on the guide 15, the cutting blade 30 is safe from injury to the operator.

Next, the operation of the peeling apparatus 1B will be described. The operator cuts the cut portion Pa of the persimmon P with the cutout device 1 </ b> A, and then presses the cut surface of the persimmon P against the suction pad 54. The pressure inside the suction pad 54 is reduced by the vacuum pump 49, and the persimmon P is suctioned to the suction pad 54 with a sufficient suction force. When the degree of vacuum in the suction pad 54 reaches a predetermined value, a detection signal is sent from the pressure sensor 53 to the sequencer 77. The sequencer 77 operates the fruit and vegetable rotation motor 48 based on the detection signal. Thereby, the persimmon P adsorbed on the suction pad 54 rotates at a relatively high speed together with the rotating pipe 50 and the suction pad 54.

FIG. 7 shows a state in which the lever 90 is at the initial rotation position. Cam follower 10 of slider 100
1 is engaged with the outermost portion 82 of the cam member 80, and the slider 100 is at a position farthest from the rotation axis C of the lever 90. The locking arm 110 is engaged with the locking pin 102 of the slider 100. The initial rotation position sensor 61 (FIG. 3) detects the shutter plate 99 of the lever 90, whereby the sequencer 77 recognizes that the lever 90 is at the initial rotation position.

The sequencer 77 includes a fruit vegetable rotation motor 48.
After the rotation of the rotary pipe 50 is started, the peeling blade drive motor 57 is operated. Peeling blade drive motor 57
Rotates, the gearbox 56 and the spindle 59
The cam member 80 rotates clockwise around the rotation axis C in FIG. On the other hand, a bearing 70 is interposed between the spindle 59 and the lever 90, and furthermore, the engagement between the locking arm 110 and the locking pin 102 causes the lever 90 to move.
Is restricted, the lever 90 does not rotate. Accordingly, as the cam member 80 rotates, the cam follower 101 comes off the outermost portion 82.

Since the slider 100 is urged toward the rotation axis C by the coil spring 94, the cam follower 1
When 01 comes out of the outermost portion 82 of the cam member 80, the cam follower 101 moves toward the rotation axis C together with the slider 100. The cam follower 101 moves along the contour of the side of the extension 81 of the cam member 80 and reaches the innermost part 83. Thereby, the peeling blade 73 mounted on the slider 100 reaches a position in contact with the outer peripheral surface of the persimmon P. The pressing force for pressing the peeling blade against the persimmon P is equivalent to the peeling blade holder 7.
2 provided by a coil spring. Cam member 80
Is further rotated, the lever 90 rotates around the rotation axis C together with the cam member 80 due to the engagement between the innermost portion 83 of the cam member 80 and the cam follower 101. Thereby, the peeling blade 73 rotates around the rotation axis C. That is, the peeling blade 73 rotates while being pressed against the outer periphery of the persimmon P, and peels the persimmon P. The lever 90 is moved about 18 around a rotation axis C orthogonal to the rotation axis of the rotation pipe 50.
By rotating by 0 degrees, the skin peeling blade 73 can peel almost the entire outer periphery of the persimmon P.

When the lever 90 rotates substantially 180 degrees, it comes into contact with the stopper pin 118. The sequencer 77 recognizes through the rotation end position sensor 62 that the lever 90 is at the rotation end position, but at this time, the rotation of the peeling blade drive motor 57 has not stopped yet. When the lever 90 contacts the stopper pin 118, the rotation of the lever 90 is restricted, but the cam member 80 continues to rotate. Therefore,
The cam follower 101 moves from the innermost portion 83 along the contour of the side of the extension portion 81 and reaches the outermost portion 82. As the cam follower 101 moves toward the outermost portion 82, as shown in FIG.
Separate from. That is, the peeling blade 73 retracts to a position sufficiently distant from the persimmon P. As shown in FIG. 9, when the cam follower 101 engages with the outermost portion 82 (that is, when the slider 100 reaches the position furthest away from the rotation axis C), the outermost sensor 64 activates the shutter plate 103 of the slider 100. The sequencer 77 detects the
It recognizes that 0 has reached the outermost position. Subsequently, the sequencer 77 immediately stops the rotation of the peeling blade driving motor 57 and stops the rotation of the cam member 80. Thereby, the peeling of the persimmon P by the peeling blade is completed.

Subsequently, the sequencer 77 rotates the peeling blade driving motor 57 in the reverse direction. Thus, the cam member 80 fixed to the spindle 59 rotates counterclockwise in the drawing toward the initial rotation position. Further, since the outermost portion 82 of the cam member 80 is engaged with the cam follower 101, the lever 90 also rotates toward the initial rotation position together with the cam member 80. When the lever 90 reaches the initial rotation position, the locking pin 102 is
Arm 110 engages a coil spring 114
Swings against the elastic force of When the locking pin 102 reaches the notch 117 of the locking arm 110, the coil spring 11
4, the locking arm 110 returns to the position before swinging, and the locking pin 102 is
17 is engaged. That is, the lever 90
It returns to the state shown in FIG.

Subsequently, the sequencer 77 operates the on / off valve 76 to supply air from the air pressure source to the nozzle 75.
And is intermittently sprayed toward the peeling blade 73. Thereby, the skin and the like adhered to the blade of the peeling blade 73 are blown off,
There is no need for the operator to manually remove the skin and the like.

Next, the sequencer 77 moves a tray (not shown) directly below the persimmon P adsorbed on the adsorption pad 54. Subsequently, after the fruit vegetable rotation motor 48 is stopped to stop the rotation of the rotation pipe 50, the air valve 53 is stopped.
Is opened to return the pressure in the suction pad 54 to the atmospheric pressure, and the persimmon P adsorbed on the suction pad 54 is dropped onto the tray. Thereby, the peeling operation of the persimmon P is completed.

As described above, according to the present embodiment, the peeling blade 73 is rotated about the rotation axis C by only one drive source (the peeling blade driving motor 57), and the peeling blade 73 is It can be approached and separated from the rotation axis C. Therefore, the apparatus configuration of the peeling apparatus 1A is simplified, and the manufacturing cost can be reduced.

In particular, when the locking arm 110 or the stopper pin 118 locks the rotation of the lever 90,
When the rotation of the cam member 80 is converted to the linear movement of the slider 100 and the rotation of the lever 90 is not locked,
Since the rotation of the cam member 80 is converted to the rotation of the lever 90, the rotation of the peeling blade 73 and the movement in the approaching and separating directions can be performed with a very simple configuration.

Further, since the outermost portion 82 and the innermost portion 83 of the cam member 80 are formed so as to hold the cam follower 101, the rotation of the cam member 80 can be easily converted into the rotation of the lever 90. Become. In addition, the rotation axis of the rotary pipe 50 that holds the persimmon P is perpendicular to the rotation axis of the lever 90 on which the peeling blade 73 is mounted.
It is possible to face almost the entire skin of the outer periphery of the vehicle.

Further, since the peeling blade holder 72 supporting the peeling blade 73 is urged against the persimmon P by the coil spring 109, the peeling blade 73 can be pressed against the outer periphery of the persimmon P with an appropriate force. Will be possible. Further, since the persimmon P is adsorbed and held by the suction pad 54, it is not necessary to stab the persimmon P with a needle-like member or the like, and therefore, the peeling can be performed without damaging the persimmon P.

Further, the perforated portion Pa of the persimmon P is cut off by the cutout device 1A, and the persimmon P is cut off by the peeling device 1B.
Since the cut surface is suctioned, the suction surface has a fixed shape, and the suction holding can be performed more reliably.

However, the present invention is not limited to this embodiment, and various modifications are possible. For example, the cutout device 1A and the peeling device 1B are not limited to the above-described structures, but may have other structures. Further, in the present embodiment, the stripper 1A and the peeler 1B are combined, but the peeler 1B may be used alone.

Furthermore, in the above-described embodiment, the configuration in which the linearly movable slider 100 is mounted on the rotatable lever 90 has been described. However, the present invention is not limited to such a configuration. Any configuration is possible as long as the drive source can rotate and linearly move the peeling blade.
Further, the shape of the cam member is not limited to the shape shown in FIG. 6 and the like, and may be another shape.

Further, in the above-described embodiment, the peeling machine for separately performing the operation of cutting the curled portion of the fruit and vegetable and the operation of peeling the skin other than the curd has been described. It is not limited to a peeling machine, for example, even if it is applied to a device configured to pierce and hold a needle-shaped member or the like in fruit and vegetables, and to perform peeling without distinguishing between a curled portion and the other. Good.

Further, in the above-described embodiment, the cutout device 1A and the peeling device 1B are controlled by the common sequencer 77, but may be controlled by separate control devices. Further, in the above-described embodiment, the edge P
The cut persimmon a was manually absorbed by the suction pad 54 of the peeling apparatus 1B.
A moving mechanism for moving the persimmon from A to the peeling apparatus 1B may be provided.
