Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a fruit peeling device used for producing star persimmons and the like.

(Prior Art) In general, farmers who produce a large amount of star persimmons have come to use vacuum-type peeling devices more frequently because of their superior workability when peeling.

This device suctions and supports the branch side of a persimmon to a suction port connected to a vacuum device, rotates this suction port with a motor, and manually presses a knife against the rotating surface of the persimmon. , continuous peeling.

However, when attaching persimmons to this vacuum-type peeling device, even if the branch side is directly inserted into the suction port, air is sucked through the gap between the calyxes that protrude like petals, and a vacuum cannot be obtained and the persimmon cannot be attached. . Moreover, the skin around the calyx is also hidden in the suction port, making it impossible to peel this area. For this reason, when using a vacuum-type peeling device, first cut off the persimmon calyx and outer skin of the calyx one by one with a knife to make the peripheral edge of the persimmon smooth without any protrusions. It is necessary to insert the branch side into the suction port. Traditionally, this peeling was done by hand, but as machines have sped up the peeling process, this has become a major hindrance, and even an experienced person can only remove around 400 peels in an hour. It was at its limit.

(Problems to be Solved by the Invention) The present invention has been made in view of the above problems. By simply holding the fruit in your hand and pressing it against the device, you can remove the stem with one touch, greatly improving work efficiency. To provide an inexpensive and small fruit dehulling device.

(Means for Solving the Problems) The present invention provides a ring-shaped blade attachment part at the tip of a rotating shaft connected to a motor, and a ring on which the calyx of the fruit comes into contact with the inner periphery of the blade attachment part. A roughly C-shaped blade body with a slit section is attached to a shaped plate material.
In addition, the cutting blade is installed in the radial direction along the slit portion of the blade body, and the tip of the cutting blade on the center side of the approximately C-shaped blade body is installed so as to protrude into the hollow portion of the blade body. It is characterized by having a support rod that passes through the shaft along the axial direction and is attached so as to be movable back and forth.

(Function) The dehulling device of the present invention rotates the cutting blade attached to the slit portion of the blade main body, which is approximately C-shaped, and places the persimmon branch on the receiving part at the tip of the branch support rod. By pushing the hem side through the hollow part of the blade, you can cut off the peripheral edge of the hem with one touch without cutting the T-shaped branch.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

In the figure, reference numeral 1 denotes a base, and a motor 2 is mounted on the base 1. Reference numeral 3 denotes a rotating shaft formed of a hollow pipe, which is supported by bearings 4 on both sides as shown in FIG. It is connected to a small diameter pulley 5B attached to the.

A disc-shaped wheel 7 is provided at the tip of the rotating shaft 3.
A ring-shaped blade attachment part 8 is connected through the ring-shaped blade attachment part 8, and this blade attachment part 8 consists of a ring-shaped attachment seat 8A and a ring-shaped holding part 8B. , 19.

As shown in FIG. 5, the blade body 9 has a ring-shaped iron plate with the center side extending to one side, and a third
As shown in the figure, it has an approximately C-shape with a slit portion 10 formed by partially notching it, and U-shaped grooves 18 and 1 on the periphery.
8 is formed. A slit portion 10 of this blade body 9 is slightly offset in the shape of a spring washer, and a cutting blade 11 is joined to one side of this slit portion 10. One end of this cutting blade 11 is curved and is attached close to the support rod 12.

As shown in FIG. 2, the branch support rod 12 is inserted into the hollow rotating shaft 3, protrudes from the wheel 7 on the tip side, and has a receiving part 1 at the tip with a cutout on one side of the upper part of the pipe.
3 is formed.

This receiving part 13 penetrates the hollow part of the approximately C-shaped blade main body 9 attached to the blade attachment part 8, and is attached to the support rod 12.
A rotation stopper 14 is attached to the proximal end side of the rotary shaft 3, and a coil spring 15 is connected thereto, so that it is always biased forward and supported by the rotating shaft 3 so as to be movable forward and backward.

Reference numeral 16 denotes a case that houses the motor 2, and an adjustment bolt 17 is attached to the back side of the case 16, so that the rear end of the support rod 12 is stopped so that the moving distance can be adjusted. .

In the figure, 20 is a persimmon, 21 is the stem of the persimmon 20, 22 is a T-shaped branch, 23 is a calyx, and 24 is a scattering prevention cover attached to the case 16 so as to cover the upper part of the blade attachment part 8. .

Next, the operation of removing the stems 21 of persimmons 20 using the apparatus having the above configuration will be explained.

First, according to the size of persimmon 20, install branch support rod 1.
The amount of movement No. 2 is adjusted using the adjustment bolt 17.

Next, turn on the switch (not shown), and
When rotated, the pulley 5A rotates from the pulley 5B via the belt 6, and the rotating shaft 3 connected to the pulley 5A rotates.
begins to rotate. As a result, the blade attachment part 8 at the tip also rotates, and the cutting blade 11 attached to the approximately C-shaped blade body 9
rotates.

At this time, the support rod 12 inserted into the rotating shaft 3
Since a stopper 14 is attached to the rear end of the blade to prevent it from rotating, it does not rotate and is urged forward by a coil spring 15, so the receiving part 13 at the tip prevents the hollow part of the rotating cutting blade 11 from rotating. It penetrates and is located at the front.

In this state, as shown in FIG. 7, if you hold the persimmon 20 in your hand and place the T-shaped branch 22 on the receiving part 13 and push it in momentarily, the receiving part 13 will be pushed by the stem 21 and support the branch. The rod 12 is pushed in until it hits the adjustment bolt 17, and as shown in FIG. 8, comes into contact with the rotating cutting blade 11 and the outer circumference of the stem 21 is cut off.

In the process of pushing this persimmon 20, the stem 2 of persimmon 20
The first side is in sliding contact with the front surface of the approximately C-shaped blade body 9 formed of an iron plate, and the cutting blade 11 cuts off the stem 21, making it stable and safe as fingers do not get inside the blade body 9. Only the outer peripheral portion of the cut stem 21 passes through the slit portion 10 and wraps around inside.

At this time, the inner diameter D of the rotating cutting blade 11 is the length T of the horizontal part of the T-shaped support 22, as shown in FIG.
Although it is smaller, if the rotation speed of the cutting blade 11 is 500 revolutions per minute, one rotation is 0.12 seconds, and the time for the horizontal part of the branch 22 to pass the cutting blade 11 is an instant of 0.01 seconds or less. Therefore, even if the tip of the cutting blade 11 is attached close to the vertical part of the support 22, the horizontal part will not be cut, and the outer periphery of the stem 21 can be cut close to the support 22. Once the periphery of the stem 21 has been cut off, when the persimmon 20 is returned momentarily, the rotating cutting blade 11
The T-shaped stem 21 passes through the hollow part of the frame without being cut, completing the process of removing the stem.

Just by pushing the persimmons 20 into the hollow part of the continuously rotating cutting blade 11, the persimmons 20 can be removed with one touch, so more than 900 pieces can be processed per minute, and the motor 2 is used in continuous rotation. Therefore, a device with a small capacity is sufficient, and the device can be made inexpensive and compact.

In addition, type 2 of persimmons whose stem side has a concave curved surface
In the case of removing the heel of a 0, it is preferable to use a blade main body 9 whose inner circumferential side protrudes forward as shown in FIG.

In addition, when adjusting the cutting range of the peripheral edge of the stem 21, loosen the screw 19 of the blade attachment part 8, lift the presser part 8B, shift the position of the U-shaped groove 18 of the blade body 9, and fix it eccentrically. By this, cutting edge 1
The radius of rotation D of the tip of 1 can be made small.

In the above embodiments, persimmons were attached to the stems, but the present invention can also be applied to other fruits.

(Effects of the Invention) As explained above, according to the device for removing the stems of fruit according to the present invention, it is possible to remove the stems with one touch, and work efficiency can be greatly improved, and the device is also inexpensive and compact. It has a great effect.
