(Vegetable transport route)
FIG. 19 shows a three-dimensional structure when the outer blade assembly 11 and the inner blade assembly 12 of FIG. 18 are viewed from above according to the arrow O. In FIG. 19, the vegetable mounting plate 24 of the mounting plate assembly 13 (see FIG. 5) is located between the outer blade assembly 11 and the inner blade assembly 12. FIG. 20 shows a three-dimensional structure in a state in which the outer blade upper plate 40 of the outer blade assembly 11 and the inner blade upper plate 28 of the inner blade assembly 12 are removed in FIG.

The vegetable transport path P is formed by the mounting plate 24 of the mounting plate assembly 13 (see FIG. 5), the outer blade guide 47 (see FIG. 13) of the outer blade unit 42, the outer blade 45, and the inner blade 33. Has been done. The actual vegetable transport path has a width corresponding to the width of the carrot to be peeled, but in FIG. 20, the center line P of the vegetable transport path is drawn as the transport path. In the case of this embodiment, the vegetable transport path P is set to exist in the horizontal plane. The inside of the horizontal plane is a direction orthogonal to the vertical direction in which gravity acts. Further, the orthogonal direction is not limited to the direction forming an angle of exactly 90 °, and even if the direction deviates from the angle of 90 ° and is tilted, vegetables can be substantially transported and tilted to some extent. It also includes cases.

When the target of peeling is vegetables other than carrots, it is possible to form the vegetable transport path P by the mounting plate 24, the outer blade 45 and the inner blade 33 without using the outer blade guide 47. Further, when the vegetable transport path P is set to exist in the vertical plane, the vegetable transport path P may be formed by the outer blade 45 and the inner blade 33 without using the vegetable mounting plate 24. It is possible.

In the case of the present embodiment, as shown in FIG. 21, the vegetable transport path P is set to have a circular shape in which the bending angle β is constant on the plus side value throughout. However, as shown in FIG. 22, the vegetable transport path P can also be set to an elliptical shape in which the bending angle β changes. Further, as shown in FIG. 23, the vegetable transport path P can be set to an oval shape having a shape such that the bending angle β is partially β = 0 °. However, as shown in FIG. 24, the vegetable transport path P is not set in a shape such that the bending angle β has a negative value. The reason is that if the shape as shown in FIG. 24 is adopted, the overall shape of the vegetable peeling device cannot be reduced in size.

FIG. 25 shows an enlarged portion indicated by an arrow Q in FIG. 20 (that is, a portion where the pair of outer blade units 42 and the inner blade unit 30 are in contact with each other). In FIG. 25, the rotation of the outer blade unit 42 urged toward the vegetable transport path P around the axis X4 by the action of the tension spring 49 is stopped by the stopper 51b. Further, the rotation of the inner blade unit 30 urged toward the vegetable transport path P around the axis X2 by the action of the tension spring 36 is stopped by the stopper 51a as shown by the arrow I. The inner blade 33 and the outer blade 45 are close to each other on the vegetable transport path P in a state where the rotation of the inner blade unit 30 and the rotation of the outer blade unit 42 are stopped by the stoppers 51a and 51b. In this state, the outer blade 45 in the outer blade unit 42 and the inner blade 33 in the inner blade unit 30 are vegetables sent along the vegetable transport path P, respectively (carrot AA in this embodiment). It is set in a state where it can be peeled.

In the present embodiment, the force by which the outer blade 45 pushes the carrot AA by the spring 49 is set to be larger than the force by which the inner blade 33 pushes the carrot AA by the spring 36. That is, the force of the outer blade 45 located on the outside of the vegetable transport path P curved in a circular shape to push the carrot AA is larger than the force of the inner blade 33 located on the inside of the vegetable transport path P to push the carrot AA. It is set to be. With this setting, the carrot AA can be smoothly moved along the vegetable transport path P even when the vegetable transport path P is curved.

Further, in the present embodiment, the tip of the outer blade 45 is located on the upstream side (left side in FIG. 25) of the vegetable transport path P with respect to the tip of the inner blade 33. As a result, the carrot AA can move comfortably along the vegetable transport path P curved in a circular shape, and the carrot AA can rotate smoothly. As a result, the carrot AA can be peeled cleanly. However, when the tip of the outer blade 45 and the tip of the inner blade 33 are at the same position along the vegetable transport path P, or the tip of the inner blade 33 is on the upstream side of the vegetable transport path P than the tip of the outer blade 45. Even when located, it is possible to peel vegetables with those blades.

(Vegetable rotation transport device)
FIG. 26 shows the vegetable skin when the top plate 8 of the main frame 3, the rack plate 9, the outer blade upper plate 40 of the outer blade assembly 11, and the inner blade upper plate 28 of the inner blade assembly 12 are removed in FIG. The planar structure of the stripping device 1 is shown. As can be understood from FIGS. 26, 4 and 2, rotating arms 10a, 10b and 10c are provided between the inner blade assembly 12 and the rack plate 9 when viewed in the vertical direction. The rotating arms 10a, 10b, and 10c are fixed to the rotating plate 54.

The rotating plate 54 is driven by an electric motor 61 provided inside the main frame 3 and rotates in the clockwise direction about the center line X5 as shown by an arrow T in FIG. 26. The rotating arms 10a, 10b, and 10c extend radially from the center line X5 of the rotating plate 54. The rotating arms 10a, 10b, and 10c rotate in the clockwise direction indicated by the arrow T about the center line X5 according to the rotation of the rotating plate 54.

As shown in FIG. 27, the rotating arms 10a, 10b, and 10c are formed of an elongated plate-shaped member having an upright portion 55 at both side ends. The upright portion 55 is formed by bending the side ends of the rotating arms 10a, 10b, and 10c upward. The rotating arms 10a, 10b, and 10c have rigidity to the extent that they do not bend. A vegetable transfer device 56 is provided at the end of the rotation arms 10a, 10b, 10c on the side far from the center line X5. The vegetable transport device 56 has two functions of pushing the rear end of the carrot to be peeled to move the carrot forward and rotating the carrot. Here, rotation is to rotate the carrot around a line passing through its center (that is, the center line).

The vegetable transport device 56 has a pinion gear 57 at its upper portion and a disk-shaped rotary disk 58 at its lower portion. A plurality of (four in this embodiment) pins 59 are provided on the circular surface of the turntable 58. Inside the vegetable transfer device 56 between the pinion gear 57 and the pin 59, there is a power conversion mechanism 60 for converting the rotation of the pinion gear 57 around the axis X6 into the rotation of the rotating disk 58 around the axis X7. It is provided. The power conversion mechanism 60 can be configured by any mechanism, and for example, a mechanism in which the rotation direction of the member is converted by a bevel gear can be adopted.

In FIG. 26, when the rotation arms 10a, 10b, 10c rotate around the center line X5 as shown by the arrow T, the rotating disk 58 of the vegetable transport device 56 rotates on the circular trajectory as shown by the arrow Y in FIG. 27. do. This circular locus Y corresponds to the circular vegetable transport path P in FIG. 26.

As shown in FIGS. 2, 3 and 4, a rack 62 is provided on the outer peripheral edge of the bottom surface of the rack plate 9 provided on the upper part of the vegetable peeling device 1. The pinion gear 57 of FIG. 27 meshes with the rack 62 of the rack plate 9 as shown in FIG. Therefore, when the rotation arms 10a, 10b, and 10c rotate in the clockwise direction as shown by the arrow T in FIG. 26, the pinion gear 57 rotates about the center line X6 in FIG. 27 as shown by the arrow U. This rotation is transmitted to the rotary disk 58 by the power conversion mechanism 60, and as a result, the rotary disk 58 rotates about the center line X7 as shown by an arrow V. This rotation is a counterclockwise rotation when viewed from the direction of the arrow W.

Since the rotation locus Y of the turntable 58 coincides with the vegetable transport path P in FIG. 26, if the carrot AA is present on the vegetable transport path P in FIG. 26, the turntable 58 in FIG. 27 rotates. When rotating along the locus Y, the turntable 58 abuts on the rear end of the carrot AA and pushes the carrot AA forward along the vegetable transport path P. Further, at this time, the four pins 59 provided on the turntable 58 pierce the rear end portion of the carrot AA. Therefore, when the pin 59 rotates about the center line X7 as shown by the arrow V, the carrot AA rotates integrally. This rotation is the rotation of ginseng AA. That is, when the rotating arms 10a, 10b, and 10c rotate as shown by the arrow T, the carrot AA placed on the vegetable transport path P in FIG. 26 rotates in FIG. 27 and draws a circular curve. It is transported along the road P. The pin 59 is a member for reliably transmitting the rotation of the turntable 58 to the carrot AA. If the rotation of the turntable 58 is transmitted to the carrot AA without using the pin 59, the pin 59 may not be used.

Since the vegetable peeling device 1 of the present embodiment is configured as described above, the worker who peels the carrot first first puts the carrot AA on the upper surface recess 67 of the vegetable supply device 5 in FIG. Put. The placed carrot AA is pushed by the pushing member 70 moving along the linear opening 68 and conveyed over the top recess 67. Since the upper surface recess 67 is formed in a V shape, the carrot AA is conveyed without falling from the recess 67.

When the transported carrot AA reaches the centering device 73 in FIG. 26, the pushing member 70 in FIG. 3 shifts to the lower traveling portion of the transport chain 69. As a result, the transport process of the carrot AA by the pushing member 70 is completed, and the carrot AA is sandwiched between the left side vegetable support member 78a and the right side vegetable support member 78b of the centering device 73 as shown in FIGS. 33 and 34. The left side vegetable support member 78a and the right side vegetable support member 78b can be freely moved by the support shafts 74a, 74b, 76a, 76b, and the movement is restricted by the tension springs 81, 82a, 82b, so that the left side The carrot AA sandwiched between the vegetable support member 78a and the right side vegetable support member 78b is set at a fixed position with respect to the vegetable transport path P in FIG. 26. The plurality of carrots AA supplied have almost the same shape, but the shapes of the fine parts are various. Even if the outer shape of the carrot AA changes variously in this way, the carrot AA is set at a fixed position with respect to the vegetable transport path P by the function of the centering device 73.

After the carrot AA is set in the centering device 73 in FIG. 26, when the rotating arm 10c rotating around the center line X5 reaches the carrot AA, the pin 59 in FIG. 27 is pierced at the rear end of the carrot AA. Since the turntable 58 supporting the pin 59 moves along the circular vegetable transport path P while rotating, the carrot AA is pushed by the turntable 58 and moves along the vegetable transport path P while rotating. ..

(Effect of this embodiment)
In the present embodiment, since the blades (outer blade 45, inner blade 33) are simply arranged instead of arranging a complicated device along the vegetable transport path P, the structure is simple and easy to manufacture. can. In addition, since the vegetables that are continuously transported without stopping are peeled while passing through the blades (outer blade 45, inner blade 33), a large amount of vegetables should be peeled in a short time. Can be done.

In the present embodiment, as shown in FIG. 26, the vegetable transport path P is formed in a circular curved shape. Therefore, the vegetable peeling device 1 can be formed smaller than the case where the vegetable transport path P is formed in a straight line. As a result, the vegetable peeling device 1 of the present embodiment can be installed in a narrow space.

In the present embodiment, as shown in FIG. 25, the tip of the outer blade 45 is located on the upstream side (left side of FIG. 25) of the vegetable transport path P with respect to the tip of the inner blade 33. Therefore, the carrot AA can move comfortably along the vegetable transport path P curved in a circular shape, and the carrot AA can rotate smoothly. As a result, the carrot AA can be peeled cleanly.

Further, the force of the outer blade 45 pushing the carrot AA by the spring 49 is set to be larger than the force of the inner blade 33 pushing the carrot AA by the spring 36. That is, the force of the outer blade 45 located on the outside of the vegetable transport path P curved in a circular shape to push the carrot AA is larger than the force of the inner blade 33 located on the inside of the vegetable transport path P to push the carrot AA. It is set to be. With this setting, the carrot AA can be smoothly moved along the vegetable transport path P even when the vegetable transport path P is curved.

In the present embodiment, in FIG. 26, the vegetable transport path P exists in the horizontal plane. And the weight of the carrot AA is received exclusively by the vegetable placing plate 24. Therefore, unnecessary force is not applied from the ginseng AA to the inner blade 33 and the outer blade 45 in FIG. 25. As a result, the inner blade 33 and the outer blade 45 can perform quick and clean peeling.

In the present embodiment, in FIG. 25, the vegetable mounting plate 24 (see FIGS. 5 and 6), the outer blade guide 47 (see FIG. 13) of the outer blade unit 42, and the outer blade 45 (see FIG. 15). The vegetable transport path P is formed by the inner blade 33 (see FIG. 8). Further, as shown in FIG. 13, a straightening plate 50 as a straightening member is provided on the upper portion of the outer blade guide 47. In FIG. 25, since the carrot AA moves on the vegetable transport path P while rotating, it may come off above the vegetable transport path P. However, in the present embodiment, since the straightening plate 50 projects above the vegetable transport path P, it is possible to prevent the carrot AA from coming off upward.
