Reference numeral 32 denotes a collecting unit for collecting the peeled persimmon 5; 35, a screw rod; and 36, a cover.

Hereinafter, the step of peeling the persimmon 5 in this machine will be specifically described.

First, the persimmon 5 to be peeled is placed on the mounting container 20 on the rotary table 18 of the pre-processing unit 3 such that the top of the perforated portion 5a of the persimmon 5 faces upward. The table 18 is intermittently rotated by about 90 ° each time.
The persimmon 5 placed on the perimeter 20 is sent to the lower part of the peeling device 25 of the peeled processed body 19 according to the pre-processing part 3, and the peeling device 25 is lowered by a predetermined distance, so that the persimmon 5 is cut off. When the plate-like blade body 27a and the plate-like body 28a abut against the 5a and the pin rods 27, 28 rise and abut on the limit switch 30, the rotating member 22a of the upright body 22 rotates to mount the mounting container. 20 is rotated, and as shown in FIG.
The area up to the circular locus line X centered at the center is removed by the plate-shaped blade body 27a to remove the skin in a flat and ring-like shape when viewed from the plane direction. Will be completed. For example, if the persimmon 5 placed on the mounting container 20 is tilted, the persimmon 5 is forcibly placed in a correct mounting state (a state in which the persimmon 5 is not tilted) by pressing from above the plate-like blade body 27a or the plate-like body 28a. ), The limit switch 30 is reliably operated, and the work of removing the curled portion 5a of the persimmon 5 is performed.

Subsequently, after the process in the pre-processing unit 3 is completed, the turntable 18 is further rotated by about 180 ° (90 ° rotation is 2 °).
Rotation), the elevating arm 31a rises, and the annular member 16 of the suction unit 4 related to the transport unit 2 which is waiting above it in advance.
In the state where the persimmon 5 is adsorbed satisfactorily in a state in which it comes into contact with the perforated portion 5a '(a flat and ring-shaped processed portion viewed from the planar direction) at the tip end surface of the persimmon 5, the permeation unit 5 is sucked by the suction unit 4 and transported The rotation base 13 according to 2 rotates about 90 ° (rotation in the vertical direction) so that the rotation arm 15 is in a horizontal state, and the persimmon 5 is located near the peeling blade 7 of the skin removing unit 1. Will be arranged. At this time, the blade member 6 of the peeling blade body 7 is in contact with the skin of the persimmon 5 at a predetermined contact angle and under a predetermined pressing force.

Subsequently, when the rotary arm 15 is rotated and the blade mounting body 34 is moved on a semicircular orbit when viewed from the front, the persimmon 5 in the pre-processing section 3 is removed.
The skin is peeled off spirally from a ′ to the tip portion to complete the skinning process. (The skinning work in the skin removing section 1 starts from a position slightly overlapping with the removing section 5a ′ in the pre-processing section 3. A stripping operation may be performed.)

Subsequently, after the skin removing step in the skin removing section 1 is completed, the rotating base 13 relating to the transport section 2 returns and rotates again, and during a series of rotating operations of the returning rotation, the suction section is rotated. Then, the suction action on the persimmon 5 in 4 is released, and the peeled persimmon 5 is introduced into the collection unit 32.

By repeating the above steps sequentially, the peeling operation of the persimmon 5 is performed.

In the present embodiment, the persimmon 5 is transported to the skin removing unit 1 before the transport in the transport unit 2 so that a predetermined portion of the fruit is formed into a predetermined shape by the pre-processing unit 3 before the transport in the transport unit 2. Because of pre-processing, the peeling work of fruits will be performed efficiently.

Therefore, according to this embodiment, the peeling operation of the persimmon 5 in the skin removing section 1 is performed more efficiently than in the conventional machine, and the workability is further improved.

In this embodiment, when the persimmon 5 is transported by the transport unit 2, the persimmon 5 is held and transported by the suction means of the suction unit 4 provided in the transport unit 2. The persimmon 5 can be sucked and held softer as compared with a structure in which the persimmon 5 is clamped by the clamping plate, so that the persimmon 5 to be transported can be transported to the skin removing unit 1 without damaging it. Specifically, for example, if the persimmon 5 has a structure in which the persimmon 5 is skewered with a needle as in, for example, Japanese Patent Laid-Open No. Hei 7-132075, bacteria enter or corrode through the puncture hole formed in the persimmon 5. Is a concern,
According to the present embodiment, such a problem is surely solved.

Further, in this embodiment, before the transport in the transport section 2, the perforated portion 5a of the persimmon 5 is removed by the pre-processing section 3 in advance. Peeling is performed on the perimeter 5a of the persimmon 5 which is considered difficult for this type of machine to perform automatically, that is, in the range from the handle 5b to the circular locus line X centered on the handle 5b. As a result, the peeling work of the persimmon 5 is efficiently performed with respect to the portion where the persimmon 5 is required to be peeled together with the skin removing unit 1, and further, the persimmon 5 removing unit 5 a in the pre-processing unit 3. Is a part for sucking and holding the persimmon 5 by the suction part 4, so that the suction effect by the suction part 4 provided in the transport part 2 can be more effectively exhibited. That is, for example, if the persimmon 5 which has not been subjected to any pre-processing is made to be sucked by the suction unit 4, the contact surface of the suction unit 4 is a leaf 5a of the persimmon 5, especially a leaf of the leaf 5a. Does not come into contact with the portion of the persimmon 5 that does not come into contact with the portion of the persimmon 5 that does not come into contact with the surface of the persimmon 5, or because the persimmon 5 has different shapes (having an uneven shape). No good suction effect such as the formation of parts and persimmons
Although persimmons 5 may not be able to be sucked, or persimmons 5 may fall from the suction unit 4 during transportation or peeling even if suction is possible, according to the present embodiment, the portion where the suction unit 4 comes into contact with is previously determined. Since the removed portion 5a 'is flattened, the persimmon 5 can be sucked in a state where the contact surface of the suction portion 4 is in good contact with the removed portion 5a' of the persimmon 5, so that the persimmon 5 can be reliably sucked. The suction action is exerted, so that the persimmon 5 can be conveyed favorably in the conveying section 2, and the work efficiency can be dramatically improved. The suction unit 4 is provided with a blowout structure that blows out suction objects such as sucked sieves and dregs.
Because of the structure capable of blowing out suction objects such as sieves and scum sucked by the above, it is possible to prevent the suction force in the suction unit 4 from being reduced or malfunction as much as possible.

In this embodiment, since the skin removing section 1 and the pre-processing section 3 are provided with an unnecessary substance removing structure for removing unnecessary substances such as the skin adhered by the skin processing section, they are continuously operated. Thus, more efficient work can be performed without any hindrance to the peeling work.
