Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a coconut peeling machine capable of automatically removing coconut husks.

[Prior art]

Coconut A, as shown in Figure 3 A and B,
A black thin shell 1 having a substantially spherical shape is covered with a husk 2 which is a hairy outer skin, and there is a white pulp 3 inside the shell 1, and the inside thereof is filled with juice 4. In addition, 5 in the figure is a bud. Husk 2 is used as fuel, Ciel 1 is used as a raw material for activated carbon and craft materials, etc., while pulp 3 is dried and made into copra, and coconut oil is taken and used as a raw material for artificial butter etc. ,
Alternatively, the juice 4 can be squeezed in a raw state to remove oil, and the juice 4 can also be used for beverages.

By the way, in producing the above-mentioned various products from coconut A, first, coconut A is
You must face Husk 2 without destroying Ciel 1. However, this work has conventionally been done manually, which is extremely inefficient.

Therefore, the applicant of this invention proposed a "coconut peeling machine" (patent application No. 59-64711) that can automatically peel the husk 2 without breaking the shell 1 first.
No.) was filed. First, this device will be explained below.

FIGS. 4 to 7 are diagrams each showing the configuration of this prior application device. In the figure, reference numeral 10 denotes a frame with a horizontal plate 11 attached to its upper surface, and a round hole 11a with a diameter larger than the diameter of the coconut A is bored vertically in the approximate center of the horizontal plate 11. There is. Further, below the round hole 11a of this horizontal plate 11, 6
The blades 12 are arranged in an annular shape at a predetermined pitch in the circumferential direction. As shown in FIGS. 6 and 7, these blades 12 have one longitudinal side 1
A cutting edge 14 is provided at one end corner of 3a, and the side 13a
A plate-shaped cutter body 13 having a predetermined length and whose other end is curved, and the side portion 1 of this cutter body 13.
It consists of a clamping plate 15 of a predetermined width attached at a substantially right angle to the curved portion of the blade 3a.
It is curved toward the third side, and both ends are curved toward the cutter main body 13 side in the width direction (direction perpendicular to the paper surface of FIG. 6). and,
These blades 12 are arranged so that the side portion 13a thereof circumscribes an imaginary circle having a diameter slightly smaller than that of the coconut A, with the clamping plate 15 positioned inward and the cutting blade 14 facing upward. Along with being
The other longitudinal side 13b of the blade body 13
The upper part of the horizontal plate 11 is attached via a hinge 17 to a mounting member 16 fixed to the lower surface of the horizontal plate 11 by fixing means such as bolts. Further, the attachment member 1 is attached to the middle part of the blade body 13.
The tip of a piston rod 19 of a cylinder device 18 such as an air cylinder rotatably attached to the piston 6 is rotatably connected. By operating these cylinder devices 18, each blade 12 can be rotated about the hinge 17 in a vertical plane as shown by arrow P, and the blade 12 can be opened.

Further, above the horizontal plate 11, as shown in FIGS. 4 and 5, a cylinder device 22 such as an air cylinder equipped with a pressing member 21 at the tip of a piston rod 20 is provided with the pressing member 21 directed downward.
Moreover, it is supported by a support bracket 23 with its axis directed in the vertical direction. When the cylinder device 22 is actuated to extend the piston rod 20, the pressing member 21 passes through the round hole 11a of the horizontal plate 11 and presses the six blades 1.
It is configured to descend through the space surrounded by 2.

Further, a husk chute 24 for receiving the husk 2 is provided below the cutter 12, and
A receiving portion 25a is located directly below the space surrounded by the blade 12.
A shell chute 25 having a shell chute 25 is disposed diagonally through the side wall of the husk chute 24. A husk transport conveyor 26 is provided at the discharge end of the husk chute 24, and a shell transport conveyor 26 is provided at the discharge end of the shell chute 25.
7 are provided respectively.

When peeling the husk 2 of coconut A using the coconut peeling machine described above, first insert the coconut A into the round hole 11a of the horizontal plate 11 with its bud 5 facing downward from the state shown in FIG. , placed on the cutlery 12. Next, when the cylinder device 22 is actuated to extend the piston rod 20, the pressing member 21 at the tip of the piston rod 20 descends and hits the top of the coconut A, pushing the coconut A downward. The coconut A has six radial cuts made in its bud 5 by the cutting blade 14 of the knife 12. Then, at the same time as the pressing member 21 is further lowered, the cylinder device 18 is actuated at a predetermined timing to retract the piston rod 19, and each blade 12 is rotated to open. Then, the coconut A tries to descend through the space surrounded by the cutter 12, but since the space surrounded by the cutter 12 is smaller than the diameter of the coconut A, the coconut A tries to move downward through the clamping plate 15 of the cutter 12. The clamping force by the clamping plate 15 and the pressing member 21
A shearing force is generated between the husk 2 and shell 1 due to the extrusion force of . Then, the shell 1 falls into the shell chute 25 without being damaged with some of the husks 2 attached, and is carried out by the shell conveyor 27. On the other hand, the husk 2 remains stuck in the cutter 12, but when the cutter 12 is further opened, it falls into the husk chute 24 below and is carried out by the husk conveyor 26.

Note that here, the opening of the shell chute 25 is as follows:
Since it is in a closed state by the pressing member 21 attached to the piston rod 20 of the cylinder device 22, the husk 2 will not get mixed into the shell chute 25. Also, if you take out Ciel 1 with some Husk 2 remaining, Husk 2
This is because if it is completely peeled off from Ciel 1, Ciel 1 will naturally crack in about a day.

Furthermore, in the above coconut peeling machine, the position of each blade 12 can be easily adjusted according to the diameter of the coconut A, and even if the size of the coconut A changes, this can be easily dealt with. can. This adjustment can be performed, for example, by changing the position of the mounting member 16 to which each blade 12 is attached by adjusting the fixing means such as bolts.

Further, in the above, the shape of the cutlery 12 is not limited to that shown in the figure, and the number thereof is also arbitrary. Further, the cylinder device 18 for rotating the blades 12 may be provided as a set for three blades 12, for example, or the cylinder device 18 on one side may be fixed, and the cylinder device 18 on the other side facing these blades 12 may be of a fixed type. 12
It is also possible to make only one portion rotatable. Further, in the above description, the cylinder device 22 is used to push the coconut A downward, but other mechanical mechanisms may be used to achieve the purpose.

The above are the details of the "coconut peeling machine" according to the earlier application.

[Problem that the invention seeks to solve]

Although the device of the prior application mentioned above is extremely superior in that it can automatically peel off the husk 2 without destroying the shell 1, it still has the following drawbacks. That is, since the holding plate 15 is curved, after the husk 2 is peeled off, the shell 1 may not fall straight down and may deviate to the side. In such a case, Ciel 1
does not fall into the shell chute 25, but instead falls into the husk chute 24, which is extremely undesirable.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a coconut peeling machine in which the shell always falls straight without being swerved to the side.

[Means to solve the problem]

This invention is characterized in that a guide member for guiding the coconut vertically downward is provided at the inner lower part of the cutter.

The difference between the cutter 12A shown in these figures and the cutter 12 of the device of the prior application is that a guide plate 30 (guide member) is attached to the center portion of the convex side of the clamping plate 15 in the width direction. The guide plate 30 has a substantially triangular shape, and one side 30a of the guide plate 30 is substantially in line with the side 13a (see FIG. 2) when attached to the clamping plate 15. In the coconut peeling machine according to the embodiment of the present invention, the blades 12A shown in FIGS. 1 and 2 are used in place of the blades 12, 12, . . . shown in FIG. 4. The coconut A falling from above the cutter 12A is incised by the cutting blade 14, the husk 2 is peeled off from the shell 1 by the clamping plate 15, and the shell 1 from which the husk 2 has been peeled is It is guided by the guide plate 30 and falls accurately into the shell chute 25.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to obtain the effect that the shell after peeling off the husk can be allowed to fall straight without always being diverted to the side.
