Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coconut peeling machine used for efficiently removing coconut husks.

Coconut A, as shown in Figure 1 A and B,
A thin black shell 1 having a substantially spherical shape is covered with a husk 2 which is a hairy outer skin, and there is white pulp 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.

The present invention was made in view of the above circumstances, and
To provide a coconut peeling machine capable of extremely efficiently peeling coconut husks.

In order to achieve the above object, the present invention provides a plurality of cutting tools arranged in an annular zone having approximately the same diameter as a coconut, the cutting edges of which are located on the inner side of the annular zone, and one along the axis thereof. The device is equipped with extrusion means for pushing out the coconut from the one direction side into the space surrounded by the blades, and a means for opening the blades near the blades. A cut is made in the husk, and in this state, the coconut is pushed out between the cutters using extrusion means, and the cutter is opened to separate the husk and shell.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 2 to 4.

In the figure, reference numeral 10 denotes a frame with a horizontal plate 11 attached to its upper surface, and approximately in the center of the horizontal plate 11 is a round hole 11a having a diameter larger than the diameter of the coconut A.
are drilled through the top and bottom. Further, below the round hole 11a of this horizontal plate 11, six blades 1 are installed.
2 are arranged in an annular shape at a predetermined pitch in the circumferential direction. These blades 12 are provided with a cutting edge 14 at one end corner of a side 13a in one longitudinal direction, and the side 13
A plate-shaped cutter body 13 of a predetermined length with the other end of a curved, and a clamping plate 15 of a predetermined width attached at a substantially right angle to the curved portion of the return portion 13a of the cutter main body 13. The clamping plate 15 is curved toward the blade body 13 as it approaches the other end of the blade body 13, and both ends thereof in the width direction (perpendicular to the plane of the paper in FIG. 4) are curved toward the blade body 13. 13
It is formed into a curved surface that is curved to the side. These blades 12 are arranged so that the side 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. and the other longitudinal side 1 of the cutter body 13.
The upper part of 3b 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. Also,
The tip of a piston rod 19 of a cylinder device (means for opening the cutter) 18 such as an air cylinder, which is rotatably attached to the mounting member 16, is rotatably connected to the middle part of the cutter body 13. . By operating these cylinder devices 18, each cutter 12 is rotated about the hinge 17 in a vertical plane as shown by arrow P.
2 can now be opened.

Further, above the horizontal plate 11, a cylinder device (pushing means) 22 such as an air cylinder equipped with a pressing member 21 at the tip of a piston rod 20 is provided.
However, with the pressing member 21 facing downward and the axis facing the vertical direction, the support bracket 23 is
It is supported and installed. 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 descends through the space surrounded by the six blades 12. ing.

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.

Therefore, when peeling the husk 2 of coconut A using the above-mentioned coconut peeling machine, first insert 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 12 of the cutter 12. Then, at the same time as the pressing member 21 is further lowered, the cylinder device 18 is operated 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 of 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 is stuck in the cutter 12 and remains there, 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 cutter 12 is attached by adjusting its fixing means such as bolts.

Incidentally, in the above description, 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. Only 12 may be made rotatable. Furthermore,
In the above, the cylinder device 22 is used to push the coconut A downward, but other mechanical mechanisms may be used to achieve the purpose.

As explained above, in the coconut peeling machine of the present invention, a plurality of blades are provided in an annular zone having approximately the same diameter as the coconut, and the cutting blades thereof are located on the inner side of the annular zone, and , are arranged so as to face in one direction along the axis of the cutlery, and in the vicinity of these cutlery, extrusion means for pushing out the coconut from the one direction side into the space surrounded by the cutlery and means for opening the cutlery are provided.
The husk can be peeled off without breaking the shell by making a cut in the coconut from its bud with a cutter, holding the coconut in that state, and opening the cutter while pushing it out with the extrusion means. Therefore, the efficiency of coconut peeling work can be further improved, and the cost in the peeling process can be significantly reduced.
