According to the first aspect of the present invention, the taro lump is moved at a high speed by the moving means, the high speed movement is blocked by the movement preventing means, and the small wrinkles can be well separated by the impact and inertia at that time.

  According to the second aspect of the present invention, since the taro lump held by the holding means is moved at a high speed in one direction and collides with the taro lump or the holding member by the fixing member, the small wrinkles can be well separated with a simple structure. .

  According to the third aspect of the invention, since the taro is moved at high speed using the elastic member to separate the gavel, the cane can be well separated with a simple structure.

Embodiments of the present invention will be described below in detail with reference to the drawings.
The taro separating apparatus 1 according to the first configuration example supports the stem side T of the taro mass W with a stem support and the root side B with a root support from above and below, respectively, and the initial position of the root support is By providing a stopper to prevent the root support from rising, when the root support moves the taro lump W from the initial position to the set position, the stem support pushes the root support back to the initial position and collides with the stopper. It is configured to separate the small potato from the taro mass.

  The main part of the first configuration example will be described. The side view is shown in FIG. 1, the view showing the working state seen from the front is shown in FIG. 2, and the plan view is shown in FIG. It comprises an elastic support 2 for mounting, a pressing part 3 for pressing the taro lump W from above, a handle link part 4 for pressing operation, a frame 5 rising in a substantially L shape, and the like.

  The individual members will be described in detail. The elastic support 2 has a coil spring (moving means, elastic member, driving means) 12 erected on a base frame 5b at the base of the frame 5, and a ring-like shape at its upper end. A seat (holding means) 13 is attached and configured. The compression stroke of the coil spring 12 is determined in correspondence with the operation characteristics of the pressing portion 3. The inner diameter dimension of the receiving seat 13 is formed to such an extent that the stem portion T of the taro lump W in the inverted posture enters.

  The pressing portion 3 includes a pressing plate 21 that is in contact with the root B of the taro lump W, a support shaft 22 that extends right above the upper surface, and a guide that guides the support shaft 22 to be slidable within a predetermined stroke range S in the longitudinal direction. It comprises a member 23g, a guide holder 23 that holds the guide member 23g, and a cam (release means) 24 that regulates the height position of the pressing plate 21 with respect to the guide holder 23. On the upper surface of the pressing plate 21, an arm (operation means) 25 for receiving the cam 24 is provided so as to project.

  The lower end of the guide member 23g is provided with a stopper (movement blocking means, fixed member) 23s for restricting the upper end position of the stroke range S of the support shaft 22, and a stroke adjusting portion 22a is provided at the base portion of the support shaft 22 to provide a predetermined value. A floating mechanism for loosely supporting the pressing plate 21 in the stroke range S is configured. The cam 24 is rotated by a motor 24d, and its rotation angle position is electrically controlled. The arm 25 gradually lowers the pressing plate 21 in accordance with the rotation of the cam 24, and then rises at a high speed to the stopper position. The idle mechanism and the cam 24 constitute an inertial impact means by a quick return operation in the upward direction.

  The handle link portion 4 connects the left and right with a support member 31 provided on the top of the frame 5, and upper and lower arms 32 and 33 that are pivotally supported on the support member 31 on the left and right sides and connected to the guide holder 23. It comprises a handle 34. The upper arm 32 is pivotally supported by the shaft support portion 32s of the support member 31 and the shaft support portion 32t of the guide holder 23, and the lower arm 33 is connected by the shaft support portion 33s of the support member 31 and the shaft support portion 33t of the guide holder 23, These upper and lower arms 32 and 33 form parallel links on both the left and right sides.

  The handle 34 extends both the left and right upper arms 32 to the front of the guide holder 23 and connects the tip thereof to the left and right. The handle 34 enables the guide holder 23 to be moved up and down in the same posture as the operator operates up and down. Furthermore, a one-way clutch 35 for holding the handle 34 at a predetermined height against the weight of the upper and lower arms 32 and 33 is provided on the shaft support portion 32s of the upper arm 32 and the like. Reference numeral 35r denotes a clutch lever that releases the one-way clutch 35 via a wire 35w.

  A sensor (not shown) for detecting the bending operation of the elastic support 2 is attached to the lower part of the frame 5. For example, this sensor is attached in a range that interferes with a part of the seat 13 of the elastic support 2. Based on the signal from this sensor, when the elastic support body 2 is bent to a predetermined position, control is performed so that the cam 24 is rotated to the fast return angular position via the motor 24d.

  In the case where the small ligature is separated from the taro lump W using the taro separation apparatus 1 having the above-described configuration, the taro lump W is placed on the elastic support 2 in an inverted posture while the handle 34 is held at the upper position by the one-way clutch 35. After that, the taro lump W is pressed downward by the pressing plate 21 by lowering the handle 34. At this time, the elastic support 2 is compressed by the pressing force of the taro lump W, and when the seat 13 is bent to a predetermined position, the cam 24 is rotated to the fast return angular position by the detection signal of the sensor. The restriction of the pressing plate 21 is released by the rotation of the cam 24, and the pressing plate 21 and the taro lump W rapidly move up by the bending reaction force of the elastic support 2. When the pressing plate 21 rises and the stroke adjusting portion 22a collides with the upper limit stopper 23s, the relative force is pressed by the pressing plate 21 and the inertial force acts on the small ridges densely formed on the outer periphery of the taro lump W. The inertia force separates the gavel from the relatives. Therefore, the taro separating apparatus 1 can efficiently separate the small jar Y from the relative X while pressing and holding the taro lump W stably by the pressing plate 21.

  When the gavel Y is separated, the operator operates the clutch lever 35r to release the one-way clutch 35 and return the handle 34 to the initial position. Then, the relative X is taken out from the elastic support 2, the next taro lump W is placed, and the handle 34 is lowered. With the configuration of the one-way clutch 35, an appropriate pressing force can be applied to various sizes of taro.

Next, a second configuration example of the taro separator will be described. In the following description, the same members as those described above are denoted by the same reference numerals, and description thereof is omitted.
As shown in FIG. 4, the side view of the taro separator 41 according to the second configuration example supports the pressing plate 21 by a support shaft 42 having a spiral groove that fits with the guide member 23g. When the pressing plate 21 rises in the idle range, it rotates by the spiral groove of the support shaft 42, so that the small scissors can be efficiently separated by the inertia force in the raising and turning directions.

Next, a third configuration example of the taro separator will be described.
The taro separation apparatus 51 according to the third configuration example holds the stem side T of the taro lumps W by the holding means, forms a protrusion on the lower side of the holding means, and lowers the holding means at high speed, thereby making the taro It is the structure which isolate | separates a gavel by making the root part of a lump collide with a projection body.
The configuration will be described in detail. As shown in FIG. 5A, the stem T of the taro lump W is formed at the lower end of the piston rod 52r of the air cylinder (driving means) 52 that expands and contracts in the vertical direction. A holder (holding means) 53 for holding is provided, and a receiving member 54 is disposed below the holder. As shown in FIG. 5 (b), the holder 53 is formed in a ring shape in which the lower end thereof can be inserted into the stem side of the taro lump W, and holds the taro lump W. A plurality of tapered protrusions 53t are formed on the inner periphery of the ring. The receiving member 54 has a peripheral wall 54w formed in a guide shape, and a protrusion (movement blocking means, fixing member) 54t is provided at the center thereof. The protrusion 54t is formed lower than the peripheral wall 54w in a height range in which the taro lump W held by the holder 53 collides when it descends.

  In the taro separating apparatus 51 configured as described above, the taro lump W held by the holder 53 is moved down at a high speed by the extension operation of the air cylinder 52 by the valve operation, and the protrusion 54t of the receiving member 54 and the root of the taro lump W Collision with B causes an inertial force to impact on the small ridges densely formed on the outer periphery of the taro lump W, and the small folds are separated from the relatives by this inertial force. At that time, the gavel is accommodated in the peripheral wall 54w without splashing outward. In this case, the receiving member 54 can be easily configured by integrally forming the protrusion 54t and the peripheral wall 54w, and can also serve as a transfer container by reducing the weight.

  By configuring the taro lump W so that it can be held sideways, it can be used even if the stem portion is defrosted, and the apparatus configuration can be reduced in weight and size. Further, by making the holding force of the holder 53 variable, it is possible to deal with a wide range regardless of the size of the taro lump W.

  Next, as shown in the side view of FIG. 6, the taro separator 61 according to the fourth configuration example has an inertial impact means by the guide holder 23 that can be quickly returned in the downward direction by the cam 24. By arranging and configuring, the same effects as described above can be obtained. Furthermore, the taro separator 71 according to the fifth configuration example also has the same effect as described above even when an elastic body is disposed on the opposite side of the taro lump W as shown in the side view of FIG.
