Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for peeling stick-shaped vegetables such as radish.

[0002]

2. Description of the Related Art Conventionally, for example, when peeling radish, the radish is first washed to remove dirt and the like, and then a worker holds the radish with one hand and uses a peeling tool held in one hand. It was customary to peel the skin manually. The pre-washing is to prevent the soil attached to the harvested radish from reattaching to the peripheral surface of the radish after being peeled off through the hands of the operator.

[0003]

The conventional manual dehulling has a drawback that the work efficiency is low because the washing work is required, and the washing work with cold water causes a pain to the worker especially in winter. there were. Moreover, the work load is large when the skin is peeled by hand, and the burden is concentrated on the wrist in particular, and there is a high probability that the worker suffers from tendonitis. further,
In such a manual work, there are disadvantages such that the skin is left unpeeled and the hand is scratched by the skin peeling tool.

Incidentally, there has been proposed a device for peeling a bar-shaped vegetable such as a radish by rolling it with a belt conveyor or a roller while contacting a cutting edge with the bar-shaped vegetable. Since it was not possible to roll the vegetables accurately by a predetermined angle, the cutting edge could not be evenly contacted with the entire peripheral surface of the bar-shaped vegetables, and if the bar-shaped vegetables had a difference in thickness or was bent, it could be cut. This type of device was rarely put into practical use because many of them interfered with blade contact.

[0005]

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention can reduce the labor of peeling work, and can peel the entire circumference of a stick-shaped vegetable evenly. An object of the present invention is to provide a peeling device that does not leave or reduce the yield and that can peel a stick-shaped vegetable without any trouble even if it has a slight difference in thickness or a bend.

[0006]

In order to achieve the above-mentioned object, a stick-vegetable peeling apparatus according to the present invention supports both ends of a stick-shaped vegetable in the longitudinal direction so that the stick-shaped vegetable can be intermittently rotated by a predetermined angle. A mechanism, and a cutting blade configured to move in the longitudinal direction of the stick-shaped vegetable while being elastically pressed against the peripheral surface of the stick-shaped vegetable supported by the support mechanism by a pressing means. is there.

[0007]

Therefore, when the longitudinal direction of the stick-shaped vegetable is moved while elastically pressing the cutting edge against the peripheral surface of the stick-shaped vegetable by the pressing means in a state where both ends of the stick-shaped vegetable are supported by the supporting mechanism, The bark-shaped vegetable peel that comes into contact with the blade is peeled off in a strip shape having a substantially constant width from one end to the other end in the longitudinal direction.
Then, after rotating the bar-shaped vegetables by a predetermined angle by the support mechanism, the cutting blade is moved again in the longitudinal direction of the bar-shaped vegetables while elastically pressing against the peripheral surface of the bar-shaped vegetables, and the bar-shaped vegetables are already peeled. The area adjacent to the cut part is peeled off in the same manner as the strip. In this way, the peeling by the cutting blade and the rotation by the support mechanism are alternately repeated, so that the whole peripheral surface of the stick-shaped vegetable is peeled.

FIG. 6 is a side view seen from above, FIG. 6 is an enlarged perspective view of an essential part showing a mounting state of a cutting blade, and FIG. 7 is a schematic view showing a power transmission mechanism related to a main motor.

In the above figures, the radish peeling device 1
Frame 3 is mounted on the pedestal 2,
From the upper part of the above, a bearing portion 5 that supports the upper support rod 4 rotatably and slidably in the vertical direction is extended forward. The upper support rod 4 has a timing belt pulley 6
The upper support rod 4 is intermittently driven to rotate by a predetermined angle by a stepping motor 7 via a timing belt. In addition, the upper support rod 4
The bearing 5 is provided with a fixing screw 8 for fixing the vertical position of the above at an arbitrary position, and a handle 9 is attached to the upper end of the upper support rod 4 to connect the timing belt pulley 6 and the handle 9. A compression coil spring 10 that winds up the upper support rod 4 is wound between them. A lower support rod 11 facing the upper support rod 4 is rotatably supported at the lower portion of the frame 3, and the opposite ends of the upper support rod 4 and the lower support rod 11 are cruciform in plan view. A protrusion is formed. The configuration including the upper support rod 4, the timing belt pulley 6, the stepping motor 7, the lower support rod 11 and the like is an example of the support mechanism in the present invention.

On the front surface of the frame 3, two guide rods 12 are provided on the left and right, and a base plate 13 is attached to the guide rods 12 so as to be slidable in the vertical direction. An arm member 15 is attached to the upper surface of the base plate 13 via a rail 14 so as to be slidable in the horizontal direction, and one end is connected to the base plate 13 and the other end is connected to the arm member 15 by a tension coil spring 16 (pressing force in the present invention). The arm member 15 is pressed toward the center side of the apparatus by an example of the means). Reference numeral 13a is a stopper that defines the movement limit of the arm member 15 on the device center side. A head member 17 is swingably supported in the vertical direction at an end portion of the arm member 15 on the device center side, and a tension coil spring 18 for urging the head member 17 downward and a head member 17 are pressed from below. An adjusting screw 19 for adjusting the angle of the lever is provided. A cutting blade 20 made of, for example, cemented carbide is detachably attached to the head member 17, and an adjusting plate 21 is attached to the head member 17 so that the width of the gap between the cutting blade 20 and the cutting blade 20 can be adjusted.

A pair of upper and lower sprockets 22 and 23 (23L and 23R) are provided on both sides of the support mechanism, and an annular chain 24 is stretched over the sprockets 23, and the sprocket 23 is rotated by a main motor 25. Is configured. That is, as shown in FIG. 7, the sprocket 25a attached to the drive shaft of the main motor 25 and the rotary shaft 2 of the sprocket 23L on the left side
A gear 23b mounted on the rotary shaft 23l is connected to a sprocket 23a mounted on the 3l by a chain.
The auxiliary gear 26b is meshed with the auxiliary gear 26b, and the auxiliary sprocket 26c coaxial with the auxiliary gear 26b and the sprocket 23c attached to the rotary shaft 23r of the right sprocket 23R are connected by a chain. As a result, the left and right chains 24 are circulated and rotated at a constant left-right speed in a direction in which the chains 24 ascend toward the center of the apparatus and descend outside the apparatus as indicated by the arrow in FIG. A columnar projecting rod 28 is attached to one place of the chain 24 via a connecting fitting 27, and the tip of the projecting rod 28 is inserted into an elongated hole 29 formed on the back side of the arm member 15. .

Therefore, the base plate 13 moves up and down while being guided by the guide rod 12 by the movement of the projecting rod 28 accompanying the rotation of the chain 24. Further, when the projecting rod 28 is on the device center side, the arm member 15 is pulled toward the device center by the tension coil spring 16 and abuts against the stopper 13a. When the projecting rod 28 is on the device outer side, Since the rod 28 abuts against one end of the long hole 29 and presses it, the arm member 15 is in a state of being moved to the outside of the device as shown by the chain double-dashed line in FIG. The radish peeling apparatus 1 of the present embodiment is provided with a micro switch 30 that can come into contact with the arm member 15 that descends when the detection lever mechanism moves to the outside of the apparatus, and a signal from the micro switch 30. Control means (not shown) for controlling the stepping motor 7 and the main motor 25 based on the above are provided.

Next, the operation of this embodiment will be described. First, the radish B is set on the support mechanism of the radish peeling device 1 which is stopped while the arm member 15 moves to the outside of the device and presses the microswitch 30. That is, the radish B having a flat portion formed by cutting off both ends is grasped by hand and the lower end thereof is pierced into the cross-shaped projection of the lower support rod 11, and then the handle 9 is pushed down to press the upper support rod 4. While piercing the upper end of the radish with the cruciform protrusion, the fixing screw 8 is tightened to fix the upper support rod 4. As a result, the radish B is supported by the support mechanism.

When the control means is turned on,
When the main motor 25 rotates, the base plate 13 starts to descend, and the projecting rod 28 moves around the sprocket 23 and moves toward the device center side, the arm member 15 is pulled toward the device center side by the tension coil spring 16, and Cutting edge 20
The base plate 13 rises in a state of being elastically pressed against the peripheral surface of the radish B from both sides, whereby the skin of the portion of the radish B that contacts the cutting edge 20 is peeled off with a substantially constant width. After the cutting blade 20 moves up to the upper end while peeling the radish B and moves around the sprocket 22 to the outside of the device, the arm member 15 is pulled to the outside of the device and the cutting blade 2
When 0 is separated from the radish B, the base plate 13 descends, and when the arm member 15 presses the micro switch 30, the main motor 25 is once stopped. In addition,
Even if the diameter of the radish B changes, the cutting blade 20 can peel the radish B while pressing it at a constant angle with respect to the axial direction of the radish B. Further, the cutting blade 20 is radish B by the tension coil spring 16.
Since it is configured to rise while being elastically pressed against the peripheral surface of the cutting blade, the cutting blade 20 can move back and forth in the horizontal direction following the unevenness of the peripheral surface of the radish B, and the radish may have some difference in thickness. Even if there is a bend, it can be peeled off without any problem.

Next, the control means is the stepping motor 7
To rotate the upper support rod 4 (that is, the radish B) at a predetermined angle (for example, 20) depending on the peeling width of the skin by the cutting blade 20.
Rotate only). Then, when the radish B has finished rotating,
The main motor 25 rotates again, and the cutting edge 20 rises while pressing against the radish B, and the part of the radish B adjacent to the already peeled part is peeled. In this way, the rotation of the radish B by the stepping motor 7 and the peeling of the radish B by the main motor 25 are alternately repeated, and the radish B is rotated by 180 ° in total, and the whole peripheral surface of the radish B is peeled. After that, when the arm member 15 presses the micro switch 30, all the operations are stopped at that time. In addition, since the radish B can be rotated by the support mechanism at an angle according to the peeling width of the cutting blade 20, the peeling can be left unpeeled,
It does not reduce the yield by scraping the already peeled part again. When the peeling is completed and the apparatus is stopped, the upper support rod 4 is pushed upward by the compression coil spring 10 by loosening the fixing screw 8 with one hand while supporting the radish B with one hand. Set another radish on and peel the skin in the same manner. The above is the operation of the present embodiment.

In this embodiment, the peeling thickness of the radish can be adjusted by rotating the adjusting screw 19 to change the inclination angle of the head member 17. In this case, the head member 17 is The closer it is to the horizontal, the thicker the skin will peel off. The peeling thickness of the radish can also be adjusted by moving the adjusting plate 21 to change the gap between the cutting blade 20 and the adjusting plate 21. In this case, the wider the gap, the larger the peeling. Will be peeled off thickly. Furthermore, the skin thickness can be adjusted by changing the tension of the tension coil spring 16.

The conventional manual peeling process requires a great deal of labor to dispose of the scraps that are widely scattered around the operator's feet, but in the present embodiment, the scraps generated are concentrated below the device. Since it will fall down, if one end of the belt conveyor is inserted in this part, the debris can be automatically carried out by the belt conveyor, and the treatment is extremely easy. Since it is a strip having a substantially constant width which is equal to the length of radish, it can be easily used for other food materials and feed. In order to make it easier for the generated debris to fall downward, it is desirable to support the radish with a support mechanism as in this embodiment.

Further, in the present embodiment, it is not necessary to peel the skin while holding the radish by hand, so that, for example, the work of setting the radish in the device and the work of removing the radish from the device should be performed by different workers. By doing so, the soil attached to the harvested radish will not be reattached to the peripheral surface of the radish after the peeling through the hands of the operator, and the washing work before the peeling work can be omitted.

Further, in the present embodiment, the cutting coil 20 is replaced with a spring having an extremely high spring constant, or the arm member 15 can be fixed to the base plate 13 so that the cutting edge 20 is surrounded by the large root. It may be possible to obtain a peeled radish with a uniform thickness and shape by not advancing and retracting following the irregularities of the surface.

The above embodiment is not intended to limit the embodiment of the radish peeling device according to the present invention. For example, in the above embodiment, the rotation angle of the radish by the support mechanism was set to 20 °. Alternatively, it may be rotated at an angle other than this depending on the peeling width of the skin by the cutting blade, and the angle may be arbitrarily adjusted. Further, the rotation of the support mechanism is not limited to that by the stepping motor. Also,
Although the cutting blades are moved by the chain in the above-mentioned embodiment, the cutting blades may be moved by the air cylinders provided in the vertical and horizontal directions. Further, in the above-mentioned embodiment, the two cutting blades are radish. However, the number of cutting blades may be one, and three or more cutting blades may be pressed against the peripheral surface of the radish at the same time. Furthermore, in the above-mentioned example, the peeling by the cutting blade was performed when the radish was stopped, but the support mechanism intermittently rotated the radish according to the peeling width of the radish by the cutting blade, and the cutting blade pressed against the radish. -It is possible that the radish is peeled in a spiral shape by gently rotating the radish when moving.

Although an example in which the present invention is applied to a radish peeling device has been described above, it goes without saying that the present invention can also be applied to a carrot, lotus root, and other stick vegetable peeling device. Absent.

[0022]

The bar-shaped vegetable peeling apparatus according to the present invention comprises:
With the support mechanism supporting both ends in the longitudinal direction of the bar-shaped vegetables, peeling the bar-shaped vegetables with a cutting blade and rotating the bar-shaped vegetables with the supporting mechanism are alternately repeated to peel the entire surface of the bar-shaped vegetables. The bar-shaped vegetables can be rotated intermittently by the support mechanism at an angle according to the peeling width of the peeling by the cutting blade, so that the peeling can be left unpeeled or the already peeled part can be peeled off. There is no such thing as shaving again to reduce the yield. Also, since the cutting edge moves elastically while being pressed against the peripheral surface of the vegetable, the cutting blade can move back and forth in the horizontal direction following the irregularities of the peripheral surface of the vegetable. Even if there is a difference or a bend, the skin can be peeled with a substantially constant thickness without causing any trouble. Further, compared with the conventional manual peeling, the work efficiency is improved and the labor required for the work is reduced, and the worker does not suffer from tendonitis or hurt his hand, and moreover, for example, a stick-shaped vegetable is attached to the device. If the work of setting and the work of removing the stick-shaped vegetables from the device are performed by different workers, the soil attached to the harvested stick-shaped vegetables will be peeled through the worker's hands after the peeling of the stick-shaped vegetables. There is no re-adhesion to the surface, and it is not necessary to wash the stick-shaped vegetables before the peeling work.
