Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a fruit processing device for peeling and simultaneously coring fruits with relatively hard flesh such as plums and apples. It is related to.

[Prior Art] Conventionally, various fruit processing apparatuses have been proposed that automatically peel or core various fruits.

For example, Japanese Utility Model Application Publication No. 62-175159 discloses a clamp rotation mechanism that holds and rotates both ends of a fruit, a cutter device that presses a rotary blade against the rotating fruit to peel it, and a cutter device that is formed at the tip of a cylindrical tube. FJ is equipped with a core removal device that presses a cylindrical core removal blade against the fruit to remove the core! An apparatus is disclosed.

However, the coring device in this processing device has a core removing blade made by gradually thinning the tip of the tube, which is pressed against the fruit, and the tube is inserted into the fruit without cutting the pulp with the core removing blade. Because of its structure, it is easy to push the tube into the fruit when the pulp is relatively soft, such as citrus fruits, or when the pulp is relatively hard, such as plums, apples, or frozen fruits. In this case, it is not easy to push a thick cylindrical tube into the pulp while cutting the pulp with a coring blade, and there are cases where core removal cannot be performed smoothly.

[Problem to be solved by the invention] The technical problem of the present invention is to solve the problem of the present invention, even when it comes to fruits with hard flesh.
To provide a fruit processing device capable of simply and reliably performing coring.

[Means for solving the problems] In order to solve the above problems, the fruit processing device of the present invention has the following features:
The above-mentioned clamp is equipped with a clamp rotation mechanism for holding and rotating the stems at both ends of fruits, a corer for removing the core of fruits, and a cutter device for peeling the fruits. The rotation mechanism includes a pair of clamp members that hold the stems at both ends of the fruit, and these clamp members are arranged at opposite ends of a pair of rotating shafts that are rotatably supported on the same axis. constituted by installing,
Further, in the coring device, a cylindrical tube having a serrated coring blade at the tip for scraping the pulp with an edge of a predetermined width is slidably inserted into one rotation shaft of the clamp rotation mechanism. The cutter device is configured such that the cutter device is arranged in a relative position such that the peeling blade contacts the surface of the rotating fruit held by the clamp rotation mechanism from the outside and cuts into the fruit. The device is characterized in that it is arranged so as to be movable along the surface of the device.

[Function] The clamp rotation mechanism holds both ends of the fruit and rotates it, then the peeling blade cuts into the fruit from the surface.
At the same time, move the peeling blade along the epidermis of the fruit.
The peeling blade can be used to peel whole fruits.

Coring of fruits with a coring device is carried out by pushing the coring blade at the tip of the cylindrical tube into the fruit while it is held in the clamp rotation mechanism, or in this case, the coring device has a sawtooth shape. Since the edge of the blade scrapes off the pulp to a specified width, the tube can be pushed in very smoothly.

Therefore, even fruits with relatively hard flesh, such as plums, apples, and frozen fruits, can be cored easily and reliably.

[Example 1] Figures 1 to 4 show examples of the fruit processing apparatus of the present invention.

The main parts of this processing device include a clamp rotation mechanism 1 for holding and rotating the stems at both ends of fruits A, a coring device 4 for removing the cores of fruits, and a corer for removing the cores of fruits A. It is comprised of a double-end cutting device 5 for cutting both ends including a portion, a cutter device 6 equipped with a peeling blade and a moving mechanism for moving the peeling blade along the fruit skin, and the like.

The pair of shift levers 20, 21 are driven to tilt toward the center, and the shift member 17.18, which is moved accordingly, moves the pair of clamp members 11.12.
If the fruit A is held between the clamp members 11 and 12 so that its center of rotation coincides with the axis of the rotation axis 1:l, 14, the fruit A will advance to the center. It will be clamped between clamp members 11,12.

A motor 30 for rotating one of the rotary shafts 13 is attached to the machine frame 1O, and the rotary shaft 13 is configured to be driven at a reduced speed from this motor 30 via the vehicle train. However, the gear 3I on the rotating shaft 13 needs to slide on the rotating shaft 13 as the rotating shaft 12 advances and retreats in the axial direction. A key 32 that engages with the gear 31 is provided, and the gear is slidably supported on the rotating shaft 13.

Therefore, regardless of the sliding position of rotation@13.14, the fruit A clamped between both clamp members 11.12 rotates due to the rotation of the motor 30, and the rotating shaft 14 rotates accordingly. become.

The rotary shaft 14 supported by the machine frame 1O has the core removed! 2
Quality 4 is attached. That is, a cylindrical tube 40 having a sawtooth core cutting blade 41 located in an annular shape at its tip edge and a handle 42 at its outer end is slidably inserted into the rotating body 14. As shown in detail in FIGS. 6 and 7, the core removal blade 41 is provided with a groove 41a at its tip that is at least as wide as the wall thickness of the cylindrical tube 40, and this edge 4]a removes the pulp. By scraping off the pulp by a predetermined width, it is possible to push the cylindrical tube 40 into the hard pulp of the fruit.

An extrusion rod 43 is provided inside the cylindrical tube 40 and is located at the end of the cylindrical tube 40 on the fruit holding side in the retracted position of the cylindrical tube 40 as shown in FIGS. 1 and 2. 43 is fixed to the machine frame 10 by screws 44. For this reason, the cylindrical tube 40 is provided with a long hole 45 in order to avoid interference caused by the bolts 44 when moving forward and backward in the axial direction.

The core of the fruit can be cut out by pushing the cylindrical pipe 40 through the handle 42 and pushing the core removal blade 41 into the fruit A.
When the cylindrical tube 40 is pulled out from the fruit by pulling the lever 42, the cut core is extruded from the cylindrical tube 40 by the extrusion rod 43.

The double-end cutting device 5 provided in connection with the shift member 17.18, as can be seen from FIGS. 1 and 3, is connected to the shift member +7. ! A support 50.51 of a cutting blade 52.53 driven by rotation @13, 14 by 8 is slidably supported on a guide rotation shaft 54, and this support 50
．． The shift member 1 is inserted into the grooves 55 and 56 provided on the outer periphery of the shift member 51.
7. Projections 17b and 18b provided at the ends of 18 are inserted. Further, the guide rotation shaft 54 is rotatably supported by the machine frame 10, and a handle 57 is fixedly attached to the guide rotation shaft 54, and the cutting blades 52, 53 and their supports So and 51 are slidably mounted. is installed so that it does not rotate if possible. Therefore, the mounting position of the cutting blade 52,5:I on the guide rotation shaft 54 is the clamp member 11.1.
Convex 11a for piercing fruits provided in 2, 1
It corresponds to slightly inside of 2a. Note that the spring 58 is used to keep the guide support shaft 54 at the return position at all times.

Therefore, the pair of shift levers 20 and 21 are driven by the clamp lever 27 so as to tilt toward the center, and the pair of clamp members 11 and 12 are driven by the shift member 17.18.
When advancing to the center and clamping fruit A, the cutting blade 5
2,5: l slides together with the support 50.51 on the guide rotation shaft 54, the cutting blade 52.53 of which is positioned slightly inside the clamping member 11.12 which is always in the fruit-holding position; When the guide rotating shaft 54 is rotated by the handle 57 against the urging force of the spring 58 while the fruit is being rotated by the motor 30, the cutting blade 52.53 is held by the clamp member 11.12 and rotates. Both ends of the fruit will be cut off.

a pair of clamp members II in the clamp rotation mechanism 1;
As shown in FIGS. 1 to 5, the cutter device 6 for peeling the fruits A supported by the holder 12 includes a cup-shaped rotary peeling blade 61 and a drive device (motor) for rotationally driving the cup-shaped rotary peeling blade 61. 62, and a moving mechanism that supports them and moves the peeling blade 61 along the fruit skin.

That is, the rotary peeling blade 61 has a blade around the entire circumference of the mouth of a cup-shaped blade, and has a structure in which a rotating shaft protrudes from the bottom of the cup-shaped blade in a direction opposite to the blade. The mouth of the cup-shaped peeling blade 61 is placed in a completely open state to continuously discharge the peeled skin, and is rotatably supported by a peeling blade support 60. In addition, the drive device 62 is fixed to the peeling blade support 60, and a belt 53 is wound between the two to remove the peeling blade 61.
The structure is such that it can be rotated at high speed.

The peeling blade support 60 to which the peeling blade 61 and drive device 62 are attached is attached to a support arm 64 that is rotatably supported around a shaft 65 with respect to the machine frame IO so that its position can be adjusted. There is. The support arm 64 consists of a horizontal portion 64a and a rising portion 64b attached to the tip thereof. In order not to obstruct the peeling blade support 60, the support arm 64 is curved laterally, and the tip of the rising portion 64b of the support arm 64 is attached to the peeling blade support 60.
Guide support rod 66.66 for adjustable position support of
protrudes horizontally.

The peeling blade support 60 has a guide support rod 66 on its lower surface.
Convex wall 67.6 with a hole through which 66 is slidably inserted.
7, and on the upper surface of the peeling blade support 60, there is provided a knob 68 having an operator 70 in the center for operating a switch 69 of the drive device 62.

Long hole 7 in the direction perpendicular to the sliding direction of the peeling blade support 60
A knob 73 is provided with an abutment 72 that can be tightened and fixed at any arbitrary position. The output connector 72 is connected to a slope 75 of a stopper 75 provided at the upper end of the rising portion 64b of the support arm 64.
a to restrict the sliding of the peeling blade support 60 on the guide support rod 66. Therefore, the position of the peeling blade 61 when the abutting element 72 is SMed on the slope 75a of the stopper 75 is adjusted.

Therefore, the abutment 72 is fixed in advance at an appropriate position in the elongated hole 71 by the nof 73, and the abutment is gripped by the nof 68 to move the peeling blade support 60 along the guide support rod 66.56. 7
When the peeling blade support 60 is rotated by the support arm 64 which is rotatably supported on the machine frame 10 on the shaft 65, the peeling blade 51 or the fruit is moved to a position where it contacts the stopper 75. It can move along the epidermis of other species and peel it off.

Fruits vary in size, shape, skin thickness, etc., and therefore it is necessary to operate the peeling blade 61 in accordance with these changes. A support rod 66. guides the peeling blade support 60.
66 to a position where the abutting element 72 comes into contact with the stopper 75, the peeling blade 61 changes the radius of rotation around the shaft 65 that supports the support arm 64, thereby peeling the fruit. The shaft 65 is mounted on a crosshead (not shown), and the shaft 65 to which the support arm 64 is attached is movable back and forth and left and right with respect to the machine frame 10, so that the peeling blade can be adjusted to any size. 5) It is possible to give movement that corresponds to the shape of the fruit.

The cup-shaped peeling blade 61 is rotated around the central axis of the peeling blade by a drive device 62, or the rotation trajectory of the surface of the fruit A is rotated while the axis is held by the clamp member. parallel to a tangent to the fruit, and in a relative positional relationship such that the outer peripheral surface of the peeling blade 61 contacts the surface of the fruit from the outside so that the peeling blade cuts into the fruit,
More preferably, the cup is rotated with the cup facing downward, and the outer skin of the fruit A is cut in the direction of the arrow.

When the peeling blade 61 is brought into contact with the surface of the fruit in this way, the cutting edge of the peeling blade that cuts the skin of the fruit always moves in the direction of the ridgeline of the cutting edge before coming into contact with the skin.
Therefore, the skin of fruits, which is relatively difficult to cut, can be easily cut. Furthermore, if the rotary blade 61 is rotated with the cup facing downward, the cut skin will turn over and fall downward, making it easier to dispose of the scraps.

A cover 77 provided behind the machine frame 10, together with a slope 78 on the machine frame opposite thereto, forms a chute 78 below the rotary blade 51 for guiding the skin removed by the rotary blade 61 to a storage container or the like. It is something to do. Further, at a lower position of the fruits to be clamped, a receiving member 79 inclined forward is provided to receive the fruits after peeling and guide them to a container or the like on the near side.

When the above fruit processing apparatus peels a spherical fruit such as a plum, first, the clamp member 11 of the clamp rotation mechanism 1 is peeled by an appropriate fruit supply mechanism or the like.
．． The cup-shaped rotary peeling blade 61 of the cutter device 6 holds the fruit between 12 and 12 with reference to its outer periphery and stem, and then rotates the fruit with rotation @ 13.
Peeling is performed by moving the core along the epidermis, then core removal is performed by pushing the core removal blade 41 at the tip of the cylindrical tube 40 of the core removal device 4 in the direction of the fruit, and then the both ends cutting device 5 The cutting blades 52 and 53 cut both ends of the fruit. As a result, it is possible to take out only the pulp part that is used for one meal. Here, in the core removal work mentioned above,
Since the pulp is scraped off to a predetermined width by the cylindrical body 40 or the edge 41a of the core removal blade 4 which has a serrated tip at its tip and is then pushed into the fruit, there is little resistance to the pushing and the core removal process is very easy. It's smooth.

The above-mentioned fruit processing equipment can be adapted to handle fruits of a wide range of shapes and sizes by controlling the movement of the rotary blade, changing the core cutting blade diameter, adjusting the blade spacing of the cutting blade, etc. I'll come.

[Effects of the Invention] As described in detail above, according to the fruit processing device of the present invention, the core removal blade in the core removal device is a tooth-shaped blade with an edge of a predetermined width at the tip, and this sawtooth Since the tube is pushed in while scraping a specified amount of pulp with the shaped core removal blade, even if the fruit has hard flesh, the thick tube can be easily pushed into the pulp, thereby removing the core. Extraction can be performed easily and reliably.
