Description

A peeling device for chest-nut}

The present invention relates to a device for automatically peeling chestnut.

The outer shell of chestnut is hard and is hard to come off simply by hand. Therefore, various chestnut peeling apparatuses have been considered before. As a conventional chestnut peeling device, for example, as disclosed in Japanese Unexamined Patent Application Publication No. 2-36427 and Japanese Patent Application Laid-Open No. 7-270, the outer shape is formed in the shape of scissors (similar to the nipper), and the pair of blades One blade in the sieve is formed in the shape of a sawtooth, and the sheath is easily inserted in the outer shell portion of the hard chestnut by preventing the chest slipping between the pair of blades. And when a sheath is carved at night, afterwards, the place which was cut by hand is enlarged and the outer skin of a chestnut is peeled off.

However, this conventional peeling device is based on the premise that a worker performs peeling work of chestnuts one by one to the last, and even an expert takes time to peel one chestnut, so, for example, If you need a large amount of food for chestnuts and chestnuts, many workers are required to peel the chestnuts, and if the number of workers is small, it is necessary to take a lot of time to peel the chestnuts. The problem is that the cost is high.

Therefore, this invention should solve the said subject, and the objective is to provide the chestnut peeling apparatus which can peel off the outer skin of several chestnuts simultaneously simultaneously.

In order to achieve the above object, the chestnut peeling device of claim 1 according to the present invention comprises a disk body rotatable in a horizontal state about a rotation axis, and the disk body along a direction crossing the circumferential direction of the disk body. One or more blades arranged so that the blade tip protrudes from the upper surface of the disc body, and the chestnut is opened at the bottom when the chestnut is stored above the annular rotation region drawn by the blade tip when the blade blade rotates. It is characterized by including a plurality of cylindrical bodies, the lower end of which is placed close to the disc body so as not to escape from the portion, and a drive unit for rotating the disc body.

According to this, since the chestnut which entered into each of the cylindrical bodies provided in multiple numbers contacts the blade body provided in the disk body which rotates from the lower side of a cylindrical body when it falls to the lower end of a cylindrical body, and a shell is peeled off by this blade body, You can remove multiple chestnuts at the same time.

Specifically, when the plurality of cylindrical bodies are arranged side by side on the same circumference around the rotational axis of the disc body, the edges of the blades at night accommodated in each cylindrical member are substantially even, and the shells are uniform. Will be directed.

Moreover, when the opening / closing door provided in the circumferential surface on the opposite side with respect to the said rotating shaft of each said cylindrical body, and the opening / closing mechanism which open and close all of these opening / closing doors at the same time, the opening-and-closing door provided in each cylindrical body using the opening / closing mechanism for the night which peeled off is provided. I can take it out in a cylindrical body at the same time by opening a door.

Specifically, the opening / closing mechanism is arranged to surround the plurality of cylindrical bodies, and is free to rotate horizontally within a predetermined angle range about the rotating shaft, and along the radial direction at a position corresponding to each opening / closing door. A ring-shaped body having an elongated engagement groove formed therein, and an engagement protrusion protruding from the opening and closing doors of the respective cylindrical bodies, and an end of which has an engaging protrusion to enter into the elongate engagement groove corresponding to the opening and closing door, wherein the ring-shaped body is formed at the predetermined angle. When rotating from one rotational end to the other rotational end in the range, the structure which rotates the said opening / closing door from a closed position to an open position can be employ | adopted.

Embodiment of the Invention

EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment of the chestnut peeling apparatus which concerns on this invention is described in detail based on an accompanying drawing.

First, the basic principle of the chestnut peeling apparatus 10 is demonstrated using FIG. 1 and FIG.

The basic configuration is arranged in the disc body 12 rotatable in a horizontal state about the rotation axis A, and in the disc body 12 along a direction crossing the circumferential direction of the disc body 12, and the blade tip. One or two or more blade bodies 14 and four blade bodies 14 rotated obliquely with respect to the disk body 12 so as to protrude from the upper surface of the disk body 12 and the blade body 14 rotate. When the chest is accommodated inside the annular rotation area drawn by the blade edge of the blade body 14 at the time, a plurality of tubular members are installed so that the lower end approaches the disk body 12 so that the chest does not escape from the lower opening part. It consists of the upper body 16 and the drive part 18 which rotationally drives the disc body 12. As shown in FIG.

The length of the blade tip of each blade body 14 which rotates together with the disk body 12 is, as described above, because each cylindrical body 16 is located above the rotation region of the blade tip. It is set to the length which passes the lower part of the cylindrical body 16, and covers the whole area | region of the opening part of the cylindrical body 16. As shown in FIG.

In addition, although the shape, the installation position, and the installation angle of the cylindrical body 16 are contained in the area | region above the rotation area of the said blade edge | tip, what kind of shape, a position, and also may be installed inclined somewhat, but in this embodiment, As an example, the cylindrical body 16 is formed in the cylinder, and each center axis | shaft becomes parallel to the rotation axis A, and is arrange | positioned side by side on the same cylinder centering on the rotation axis A at the same time. This is for the blade tip of the blade body 14 to the night accommodated in each cylindrical body 16 to be equal, and to allow each chestnut to peel off at about the same time.

According to this basic configuration, the chestnut introduced into the tubular body 16 from the upper end portion of each cylindrical body 16 falls toward the rotating blade body 14 facing the lower end portion of the tubular body 16, and the blade When abutting (contacting) the blade edge of the sieve 14, part of the shell is peeled off. Chestnut rotates by the contact with the rotating blade body 14 and springs up to the inner surface of the tubular body 16, falls back toward the blade body 14, and contacts the blade edge of the blade body 14, Some peel off

When this operation is repeated for a predetermined time, since the contact position with the blade of the chestnut 14 changes randomly, the chestnut peels off substantially uniformly. This predetermined time can be obtained empirically by actually peeling a plurality of chestnuts using this chestnut peeling device 10. In general, the chestnut may be peeled from the outermost shell, which is called the outer shell. However, by setting the predetermined time longer, the inner shell and the so-called inner shell may also be peeled off automatically.

In this way, the operator puts chestnuts into the plurality of tubular bodies 16 and only takes out chestnuts from the tubular bodies 16 after a predetermined time has elapsed, so that the shells or chestnuts with their outer shells and shells peeled off can be obtained. The efficiency of peeling work is remarkably improved compared with the case of peeling one by one conventional.

As described above, the operator may take out the chestnuts inside each cylindrical body 16 one by one after a predetermined time has elapsed. However, in order to improve workability, the rotary shaft A of each cylindrical body 16 is improved. When the opening / closing door 20 is installed on the opposite circumferential surface and the opening / closing mechanism 22 for opening / closing all the opening / closing doors 20 at the same time is in contact with the blade 14 rotating in each cylindrical body 16. As the night springs out, the night springs out of the tubular body 16 by simply opening and closing the door 20. Therefore, the trouble of taking out chestnuts one by one inside each cylindrical body 16 is abbreviate | omitted, and the taking out operation is performed in a short time.

Next, the structure of the actual peeling device 10 is demonstrated using FIG. In addition, about the structure demonstrated by basic structure, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

The base 24 is formed as an example of a rectangular or cuboid box, and an electric motor (not shown) constituting the drive unit 18 is housed therein. And as an example, the output shaft 26 of an electric motor protrudes perpendicularly from the upper surface center part of the base 24, and the disk body 12 is horizontally provided in this output shaft 26. As shown in FIG. As a result, the rotation axis A of the disc body 12 coincides with the axis line of the output shaft 26. Instead of the configuration in which the output shaft 26 of the electric motor directly protrudes from the base 24, an output shaft 26 separate from the output shaft of the so-called electric motor is rotatably provided on the base 24, and this output shaft ( 26) Various transmission mechanisms, such as reduction gears, gears, pulleys, and endless belts, may be arranged between the output shafts of electric motors.

Although the installation direction of the blade body 14 to the disk body 12 is provided radially along substantially radial direction as an example in this embodiment, in the rotational direction of the disk body 12 from a radiation image, or a half rotation direction It may be provided at a position which is moved in parallel a little, and may be arrange | positioned slightly in the radial direction, and various changes are possible.

In addition, four first pillars 28 are set up at four corners of the upper surface of the base 24, and a cylindrical blade cover covering the disc body 12 and the blade body 14 is provided on the first support body 28. 30 is provided. In detail, the flange part 30a provided in the lower end of the blade cover 30 is screwed to the 1st support | pillar 28. As shown in FIG.

And as described above, the plurality of cylindrical bodies 16 do not interfere with the blade 14 rotating at the lower end thereof, and the lower end, the blade 14, and the disc above the disk 12. It is arrange | positioned so close that a night does not escape from the space | interval with sieve 12.

In detail, each cylindrical body 16 is being fixed to the upper surface of the substantially disk-shaped mounting base 32 provided in the upper end of the cylindrical part of the blade cover 30. As shown in FIG. And the inner region of each cylindrical body 16 of the mounting base 32 is cut out according to the inner diameter of the cylindrical body 16, and when the inside of the cylindrical body 16 is observed from the upper opening part of the cylindrical body 16. It has a structure in which the disc body 12 and the blade body 14 can be seen.

Moreover, as mentioned above, the opening-closing door 20 is provided in the circumferential surface on the opposite side with respect to the rotating shaft A of each cylindrical body 16, respectively, and is rotatable freely. The opening / closing door 20 is formed by cutting a part of the outer surface of the cylindrical body 16 into a semi-cylindrical shape, and by the hinge 34 provided on the outer surface of the cylindrical body 16, the cylindrical column 16 is further lined up. It can be rotated about a rotation axis parallel to the central axis of the cylindrical body 16 to the outside.

Moreover, one 2nd support | pillar 36 stands up in the center of the mounting stand 32 on the rotating shaft A of the disk body 12, and the opening and closing mechanism 22 of the 2nd support | pillar 36 is installed in the upper end of this 2nd support | pillar 36. As shown in FIG. A part of the supporting disc 38 is fixed.

In the support disc 38, four circular holes 38a are opened in accordance with the position of the cylindrical body 16, and when the support disc 38 is provided in the second support 36, each cylindrical body 16 is formed. An upper portion of is inserted into this circular hole 38a, and is configured to protrude from the upper surface of the support disc 38. As shown in FIG. And, the rubber cap 40 is mounted on the upper portion of each protruding cylindrical body 16, but the rubber cap 40 is provided with a cross cut portion 40a as an example, as shown in FIG. It can be inserted into the cylindrical body 16 as if it pushed in from the rubber cap 40, and after the chestnut was accommodated in the cylindrical body 16, the chestnut body 14 in the cylindrical body 16 may be inserted. Even if it protrudes in contact with, it does not protrude from the inside of the cylindrical body 16.

Further, the lower side of the support disc 38 is arranged so as to surround the plurality of cylindrical bodies 16, and is free to rotate horizontally within a predetermined angle range around the rotation axis A, and to each opening and closing door 20. The ring-shaped body 44 in which the elongate engaging groove 42 along the radial direction was formed in the corresponding position is provided. This ring-shaped member 44 forms part of the opening and closing mechanism 22.

As for the mounting structure of the ring-shaped body 44 to the support disc 38, four columnar protrusions 46 are provided in the vicinity of the outer periphery of the lower surface of the support disc 38 as an example, and each column-shaped protrusion 46 is provided. Each columnar projection 46 is inserted into four arc-shaped grooves 50 provided in the ring-shaped body 44 with the spacer 48 mounted. In addition, the fall prevention ring 52 is fixed to the lower end of each columnar projection 46 protruding downward from the arc-shaped groove 50.

By this structure, the ring-shaped body 44 is predetermined below the support disc 38 by the length of the spacer 48, and is predetermined around the second support 36 within the length range of the arc-shaped groove 50. The rotational movement is free within the angular range of. In addition, a spring 54 is arranged between the ring member 44 and the support disc 38, and both ends thereof are fixed to the ring member 44 and the support disc 38, respectively. The support disk 38 is pressurized to be always rotated in the direction of arrow B in FIG.

Moreover, the engaging protrusion 56 which protrudes toward the ring-shaped body 44 direction is provided in the outer surface of the opening / closing door 20 of each cylindrical body 16. As shown in FIG. In this embodiment, a part of the opening / closing door 20 is cut | disconnected and stood up in a horizontal direction as an example, and the engaging protrusion 56 is formed by the screw or pin being fitted in this standing part 20a. In this embodiment, it is a screw as an example. The engaging projection 56 also constitutes a part of the opening and closing mechanism 22. And the engaging projection 56 provided in each opening-and-closing door 20 enters into the elongate engagement groove | channel 42 provided in the ring-shaped body 44 with the front end corresponding to the opening-and-closing door 20, respectively.

By this structure, when the ring-shaped body 44 is rotated in the direction of arrow B by the spring 54 and is located at one rotational end in a predetermined angle range (state of position C in FIG. 1 or state of FIG. 3). ), The engaging projection 56 is located at the extreme end of the inner diameter side of the elongated engaging groove 42, and the opening and closing door 20 is in the closed position. And, when the ring-shaped body 44 is rotated in the opposite direction to the arrow B against the pressing force of the spring 54, the engaging projection 56 is pressed out in contact with the inner surface of the elongated engaging groove 42 gradually toward the outside With it, all of the opening and closing doors 20 are opened in turn at the same time. And, when the ring-shaped body 44 is located at the other rotational end of the predetermined angle range, the engaging projection 56 also reaches the end of the outer diameter side of the long engaging groove, and all the opening and closing doors 20 are most opened. State, and eventually into an open position (state of the portion D of FIG. 1 or state of FIG. 4). In particular, part D of FIG. 1 partially shows a state in which the ring-shaped body 44 is located at the other rotational end, and the engaging protrusion 56 entering into the elongate engaging groove 42 included in the part D is provided. The installed door 20 is in the closed position.

Next, operation | movement of the chestnut peeling apparatus 10 is demonstrated using FIGS.

First, the electric motor is operated to rotate the blade body 14 together with the disc body 12.

In this state, the chestnut 58 is pushed in from the cut part 40a of the rubber cap 40, and all the cylindrical bodies 16 are put in.

The thrown chestnuts fall downward in the tubular body 16 and come into contact with the blade body 14 that is installed and rotated in the disc body 12 arranged to block the lower end portion of the tubular body 16. Since the blade body 14 is rotating at a high speed, the chestnut 58 falling to the bottom of the cylindrical body 16 bounces off the inner surface of the cylindrical body 16 in contact with the blade tip of the blade body 14. , Again touch the edge of the blade and repeat the action. And whenever the chestnut 58 contacts the blade edge of the blade body 14, the chestnut 58 is peeled off.

If this operation is repeated for a predetermined time, the chestnut 58 will continue to spring and rotate in the tubular body 16 and repeatedly contact with the blade tip of the blade body 14, so that the outer shell part is peeled off to every corner. Moreover, the time when this outer shell part peels to every corner is the rotation speed of the disc body 12, the number of the blade bodies 14 provided in the disc body 12, and the blade which protrudes from the disc body 12. It can be found empirically by peeling off several chestnuts 58 in the state which made the angle of the blade edge part of the sieve 14 constant. Moreover, when peeling off an inner shell, what is necessary is just to delay the time which takes out a chestnut for a predetermined time further.

Subsequently, when a predetermined time elapses after the night is put, the rotational movement of the ring-shaped body 44 is located at the other rotational end of the predetermined angle range in the direction opposite to the arrow B against the pressing force of the spring 54. Let's do it. In this embodiment, since the rotational motion lever 60 is provided in the ring-shaped body 44, the ring-shaped body 44 is rotated with this rotational motion lever 60. As shown in FIG.

As described above, when the ring-shaped body 44 rotates to the other rotary end, the engaging protrusion 56 installed in the opening / closing door 20 moves outward in the elongated engagement groove 42, and the longer engagement groove It reaches the edge part of the outer diameter side of 42, and all the opening / closing doors 20 become an open position. Thereby, the night 58 springing up in the inner space of all the tubular bodies 16 protrudes from the opening / closing door 20 in the open state to the exterior of the tubular body 16, and from all the tubular bodies 16 inside. You can have chestnuts at the same time, or peeled chestnuts, both peeled and peeled.

Moreover, when opening and closing the door 20, the night protrudes vigorously from the cylindrical body 16 as mentioned above. Moreover, the peelings peeled off by the blade body 14 from the night fall while flying inside the cylindrical part of the blade cover 30 in the downward direction of the disk body 12. As shown in FIG. Therefore, in order to prevent peeled chestnuts and crumbs from scattering around the chestnut peeling device 10, the entire peeling device 10 may be covered with an inverted cup-shaped plastic cover. In this case, an opening is provided in the upper portion of the plastic cover so that the rubber cap 40 provided at the upper end of the tubular body 16 is exposed, and the rubber cap 40 is exposed. Moreover, the lower end of a vinyl cover is made into the shape extended at least below the blade cover 30 of the disk body 12 at least.

In the above embodiment, the number of the tubular bodies 16 is four as an example, but two, three, five,... If a plurality, etc., may be provided. In addition, the size of the cylindrical body 16 can be thrown into the cylindrical body 16 by one chestnut, and the chestnut which jumped in the cylindrical body 16 after contacting the blade body 14 as mentioned above was put in the chestnut body as mentioned above. As long as there is a space area large enough to rotate and contact the blade body 14 again, it may be of any inner diameter. Moreover, although the external shape of the cylindrical body 16 was also made into the cylinder as an example, you may make it a polygonal cylindrical body. Moreover, even if two or more chestnuts are thrown in, if each chestnut can contact the blade body 14 to every corner in the tubular body 16, you may use it by making a several chestnut into the tubular body 16, but it is common. Since nonuniformity arises in any way, the peeling quality improves in one side so that only one chestnut may be thrown into the cylindrical body 16. As shown in FIG.

Moreover, in order to prevent the nonuniformity in the peeling degree between each cylindrical body 16 as mentioned above, each cylindrical body 16 is arrange | positioned on the same circumference centering on the rotating shaft of the disk 12. In addition, although the blade tip area of the blade body 14 which passes through the bottom of the cylindrical body 16 and contacts the chestnut 58 is the same, and the speed of the blade tip when it touches the night is also approximately the same, The cylindrical body 16 may be further arranged on the circumference larger in diameter than the other cylindrical body 16 in the rotational region, and the chestnut having a large external shape may be introduced into the cylindrical body 16 to peel off. The farther away from the axis of rotation (A), the faster the speed of the tip of the blade when it touches the night, thereby increasing the amount of shell peeled off when it comes into contact with the tip of the blade at a large impact force, and even at night larger than other nights. Because you can peel off at about the same time as another night.

In addition, in the above-mentioned embodiment, although the opening-closing door 20 provided in each cylindrical body 16 was a structure which rotates around the rotating shaft parallel to the central axis of the cylindrical body 16, the upper side of the opening-closing door 20 was made. It is good also as a structure which a hinge opens and opens so that it may protrude.

In addition, although the opening / closing mechanism 22 was comprised as the ring-shaped body 44, the long engaging groove 42, the engaging protrusion 56 provided in the opening-closing door 20, etc. as an example, it is limited to this structure. Instead, the torsion coil springs are always provided to the opening and closing doors 20 in the closing direction, and the ring-shaped body 44 and the opening and closing doors 20 may be connected by cables. Various kinds of mechanisms can be employed.

As mentioned above, although preferred embodiment of this invention was described variously, this invention is not limited to the above-mentioned embodiment, Of course, many changes can be made in the range which does not deviate from the mind of invention.

According to the chestnut peeling apparatus which concerns on this invention, the chestnut which entered into each cylindrical body provided in multiple numbers comes into contact with the blade body provided in the disk body which rotates below the cylindrical body, when it falls to the lower end of a cylindrical body, As a result, the shell is peeled off, so that a plurality of chestnut peels can be peeled off at the same time, and the efficiency of the peeling off work is remarkably improved.

In addition, if an opening door is installed in each cylindrical body and an opening mechanism for opening and closing the door at the same time, the peeled chestnut can be taken out of the cylindrical body at the same time by opening the opening and closing door installed in each cylindrical body using the opening and closing mechanism. In addition, there is an effect that the work efficiency can be further improved.
