JP 2005-218323 A

  In the above-described conventional skinning processor, since the height of the nozzle is fixed, there is a problem that compressed air cannot be evenly blown in the height direction of the eaves placed on the bottom surface in the duct.

  Therefore, in a skinning process using a conventional skinning machine, an operator moves the eaves up and down in the duct or twists the hand to rotate the eaves around the axis. Since compressed air is blown around the entire circumference of the bag, there is a problem that work efficiency is lowered.

  This invention solves an above-described problem, and makes it a subject to provide the peeling processing machine which can spray compressed air uniformly and effectively with respect to the whole surface of vegetables.

In order to solve the above-mentioned problems, the present invention is a skinning processing machine that blows compressed air onto the skin of vegetables to remove deposits from the vegetables. The skinning processor includes a processing unit having a mounting surface on which the vegetables are mounted, a nozzle provided in the processing unit, a compressed air supply device that supplies compressed air to the nozzle, and the nozzle And a drive device for reciprocating the nozzle in the radial direction of the cross section of the vegetables. The drive device has an elevating member that is movable in the radial direction of the cross section of the vegetables, and the nozzle is attached to the elevating member. The nozzle is configured to eject compressed air while reciprocating in the radial direction of the cross section of the vegetables.

In this configuration, the nozzle blows the compressed air to the vegetables while reciprocating in the radial direction of the cross section of the vegetables, so the compressed air is blown from a wide range in the height direction or the lateral direction to the vegetables.
Therefore, in the peeling processing machine of this invention, compressed air can be uniformly sprayed with respect to the whole surface of vegetables arrange | positioned at the process part.

Moreover, in the peeling processing machine of this invention, compressed air is sprayed intermittently with respect to the same location of the skin of vegetables because a nozzle reciprocates to the radial direction of the cross section of vegetables. That is, the impact by compressed air is repeatedly applied to the same place of the vegetable skin. Thereby, the peeling effect of the deposit | attachment of vegetables can be improved, and compressed air can be efficiently sprayed with respect to vegetables.
Therefore, in the skinning processor of the present invention, the working time of the skinning process can be shortened and the amount of compressed air used can be reduced, so the operating time of the compressor that supplies the nozzle with compressed air is shortened. In addition, the energy efficiency of the skinning process can be improved. As a result, power consumption can be reduced and generation of carbon dioxide can be reduced.

You may provide the sensor which detects that the said vegetables were arrange | positioned at the said process part in the above-mentioned skinning processing machine. And when the said sensor detects that the said vegetables were arrange | positioned at the said process part, while the said nozzle reciprocates to the radial direction of the cross section of the said vegetables by the said drive device, from the said compressed air supply apparatus It is desirable that the nozzle is configured to be supplied with compressed air.
In this structure, when vegetables are not arrange | positioned at a process part, since compressed air is not ejected from a nozzle, the energy efficiency of a skinning process can be improved.

In the above-described skinning processor, when the driving device has an electric motor and a lifting member movable in the radial direction of the cross section of the vegetables, and the nozzle is attached to the lifting member. Preferably, the rotating shaft of the electric motor and the elevating member are connected via a crank mechanism.
In this configuration, the nozzle can be reciprocated in the radial direction of the cross section of the vegetables without being affected by the ambient temperature.

In the peeling processing machine of the present invention, the nozzle can spray the compressed air evenly over the whole surface of the vegetables by spraying the compressed air on the vegetables while reciprocating in the radial direction of the cross section of the vegetables. . Moreover, since the peeling effect of the deposits of vegetables improves, compressed air can be efficiently sprayed with respect to vegetables. Therefore, in the skinning processing machine of the present invention, it is not necessary for the operator to move the vegetables in the vertical direction in the processing unit, or to rotate the vegetables by twisting their hands, thereby improving the work efficiency of the skinning process. In addition, the energy efficiency of the skinning process can be improved.

In the state where the elevating member 44 is disposed at the lowest position, the injection ports 31 (see FIG. 3B) of both the nozzles 30 and 30 are closest to the placement surface 11a.

As shown in FIG. 4A, when the rotary shaft 42b of the electric motor 42 is rotated and the disk member 46a rotates clockwise (clockwise) in FIG. 4A, the roller 46c is directed diagonally upward to the left. Move.
At this time, the roller 46c pushes the slide member 45 upward while rolling in the guide groove 45a of the slide member 45 toward the left side.
As a result, the elevating member 44 moves upward, and the nozzle support plate 20 and both nozzles 30, 30 move upward in conjunction with the elevating member 44.
In addition, when the nozzle support plate 20 moves upward, the protruding plate 13 is configured to enter the recess of the mounting portion 21.

  When the rotating shaft 42b further rotates and the roller 46c moves to the highest position as shown in FIG. 4B, the slide member 45 and the elevating member 44 are also arranged at the highest position, and both the nozzles 30, 30 are at the highest position. Be placed.

When the rotary shaft 42b further rotates from the state where both the nozzles 30 and 30 are disposed at the highest position, the roller 46c moves obliquely downward to the right.
At this time, the roller 46c pushes the slide member 45 downward while rolling in the guide groove 45a of the slide member 45 toward the right side.
As a result, the elevating member 44 moves downward, and the nozzle support plate 20 and both nozzles 30, 30 move downward in conjunction with the elevating member 44.

  Thus, in the drive device 40, when the rotating shaft 42b of the electric motor 42 makes one rotation, both the nozzles 30 and 30 are configured to reciprocate once in the vertical direction.

Next, the peeling process using the above-described peeling processing machine 1 will be described.
As shown in FIG. 2, when the long paper N is placed at the skinning position of the placement surface 11 a of the duct 10, the sensor 60 detects the long paper N or the operator's hand, and the detection signal is transmitted to the control device ( (Not shown).

  When the detection signal is input, the control device drives the electric motor 42 (see FIG. 3B) as shown in FIG. When the electric motor 42 is driven, the rotating shaft 42b rotates. Thereby, the driving force of the electric motor 42 is transmitted to the elevating member 44 via the crank mechanism 46, and both the nozzles 30 and 30 reciprocate in the vertical direction above the mounting surface 11a (FIG. 4 (a) and (See (b)).

  Further, when the detection signal is input, the control device opens an on-off valve (not shown) of the compressed air supply device 50. Thereby, compressed air is supplied to both nozzles 30 and 30 through both supply hoses 51 and 51 from a compressor (not shown).

Then, as shown in FIGS. 4 (a) and 4 (b), both nozzles 30 and 30 inject compressed air toward the long wall N while reciprocating in the vertical direction (see FIG. 2). Is sprayed on the skin of Nagatoro N.
The operator removes the deposit by blowing compressed air over the entire long wall N by pulling the long wall N forward from the duct 10.

  When the long wall N is pulled out from the duct 10, no detection signal is output from the sensor 60. Then, the control device stops the electric motor 42 and closes the open / close valve of the compressed air supply device 50. Thereby, the vertical movement of both nozzles 30 and 30 is stopped, and the supply of compressed air to both nozzles 30 and 30 is stopped.

In the skinning processor 1 as described above, as shown in FIGS. 3 (a) and 4 (b), both nozzles 30 and 30 reciprocate in the vertical direction to blow compressed air onto the long wall N, Compressed air is blown from a wide range in the height direction to the long wall N.
Moreover, compressed air can be efficiently sprayed with respect to the long wall N from the injection port 31 (refer FIG. 2) of the nozzle 30. FIG.

  Therefore, in the skinning processor 1, the compressed air can be evenly blown against the height direction of the long wall N placed in the duct 10. That is, compressed air can be evenly sprayed on the entire circumference of the long wall N in a state where the long wall N is mounted on the mounting surface 11 a in the duct 10. This eliminates the need for the operator to move the eaves N up and down in the duct 10 and to twist the hand to rotate the eaves N about the axis, thereby improving the work efficiency of the skinning process. Can do.

Further, in the skinning processor 1, the compressed air is intermittently blown against the same place on the skin of the long basket N as the nozzle 30 reciprocates in the vertical direction. That is, the impact by the compressed air is repeatedly applied to the same place of the skin of the long basket N (for example, 20 to 30 times per second). Thereby, the peeling effect of the deposit | attachment of Nagatoro N can be improved, and compressed air can be efficiently sprayed with respect to vegetables.
Therefore, in the skinning processor 1, the working time of the skinning process can be shortened, and the amount of compressed air used can be reduced (the amount of compressed air used is lower than that of a conventional skinning processor). 20-30% reduced). Thereby, the operation time of the compressor (not shown) which supplies compressed air to the nozzle 30 can be shortened, and the energy efficiency of a skinning process can be improved. As a result, power consumption can be reduced and generation of carbon dioxide can be reduced.

  Further, in the skinning processor 1, when the long wall N is not arranged in the duct 10, the compressed air is not ejected from both the nozzles 30 and 30, so that the energy efficiency of the skinning process can be improved.

  Further, in the skinning processor 1, as shown in FIG. 3B, the rotating shaft 42 b of the electric motor 42 and the elevating member 44 are connected via a crank mechanism 46. Thereby, the nozzle 30 (elevating member 44) can be moved in the vertical direction without being affected by the ambient temperature (air temperature).

  Further, as shown in FIG. 2, the skinning processor 1 is provided with a cover 15 that closes the protruding plate 13 side and the upper side of the nozzle 30, so that the old skin removed from the long fistula N during the skinning process It is possible to prevent dust such as dirt from adhering to the nozzle 30.

Further, as shown in FIG. 3B, a rear wall portion 22 a is formed at the rear portion of the nozzle support plate 20. As shown in FIG. 4B, when the nozzle support plate 20 moves upward, the rear wall portion 22a is exposed above the placement surface 11a.
Thereby, it is possible to prevent dust such as old skin and dirt from entering the lower part of the nozzle support plate 20 from the inside of the duct 10 during the skinning process by the rear wall portion 22a. Can be prevented.
