[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a peeling machine for a long onion, which is equipped with a nozzle for blowing compressed air onto the long green onion to blow away unnecessary substances such as old skin and mud adhering to the surface of the long onion.

[0002]

2. Description of the Related Art When shipping the onion produced, the leaves and roots of the onion are cut, and then compressed air is blown to the epidermis of the onion to blow away unnecessary substances on the surface of the onion. A peeling process is performed. In addition, the unnecessary material refers to old skin or mud attached to the surface of the onion. As a peeling machine for performing such peeling treatment, a left nozzle and a right nozzle for ejecting compressed air are erected on the left and right sides of the peeling position, respectively, and a long green onion is set between them to blow compressed air. There was an aspect. In the right and left nozzles of this peeling machine, for example, two jet outlets are formed vertically apart from each other. Further, there is a mode in which an upper nozzle and a lower nozzle for ejecting compressed air are arranged separately at upper and lower positions of a skinning position, and a leek is set between them to blow compressed air. In the upper nozzle and the lower nozzle in the peeling machine of this aspect, the ejection ports are separated from each other on the left and right, for example, 2
It was formed one by one.

However, in the case of the latter of the peeling machines in which the upper nozzle and the lower nozzle are arranged above and below the peeling position of the latter, a long onion to be peeled is laterally disposed between the upper and lower nozzles. It had to be inserted, and there was a side inferior in workability. In this respect, in the case of the former one in which the left nozzle and the right nozzle are erected on the left and right of the peeling position, it is possible to insert the onion from above between the left and right nozzles when performing the peeling process. Moreover, the workability was excellent.

[0004] The skinning machine lateral nozzles is provided on the left and right of the skinning position in the prior described with reference to FIG. 14, skinning machine 61 has a frame 6 2, gantry 6 2
A left nozzle 6 3 and a right nozzle 6 4 are installed on the upper part of the onion N, which blow compressed air onto the epidermis N to remove unnecessary substances. These nozzles 6 3, 6 4 are respectively arranged on the left and right of the skin peeling position P where the long green onion N to be skinned is set, and are connected to a compressor (not shown). Further is leek detecting sensor 6 5 is provided for detecting that the leek N is set to skinning position P, by leek detecting sensor 6 5 detects the leek N, nozzles from compressor Compressed air is supplied to 6 3, 6 4. In addition, the nozzles 6 3, 6 are located behind the peeling position.
Dust collecting net 6 6 there is arranged a 4 blown away by compressed air ejected from collecting waste material removed from the leek N.

[0005] To explain this skinning machine 61 by the strip skin treatment, worker in hand leaves of onions N, the leek N from above the opening between the nozzle 6 3, 6 4 Insert and set in peeling position P between the nozzles 6 3, 6 4. At this time, the long onion N is set according to the injection height of the nozzles 6 3 and 6 4. Once leek N is set to skinning position P, and the leek N detected by the leek detection sensor 6 5, compressed air is supplied to the nozzle 6 3, 6 4 from the compressor. Compressed air is blown from the nozzles 6 3 and 6 4 toward the epidermis of the long onion N to blow off and remove the unnecessary substances adhering to the surface of the long onion N. As it is, the worker is the long green N
Is pulled out to the front, and the blowing position of the compressed air in the long onion N is sequentially moved to the back in the longitudinal direction of the long onion N. In this way, unnecessary substances are blown off and removed from the entire onion N. Blown The waste material is collected by the dust collecting net 6 6. In this way, the peeling treatment of long green N was performed.

[0006]

However, in the above-mentioned conventional peeling machine, since compressed air is blown from the left and right sides of the onion to be stripped, the onion is lifted by the flow of compressed air, which is preferable. In some cases, it was not possible to carry out the peeling process. In addition, since long onions are agricultural products, they have various shapes and are not limited to straight ones, and many bent onions are slightly included. However, in the conventional peeling machine, the compressed air is jetted only from the right and left two directions. Therefore, when the onion is bent, the compressed air is not spread all over the place. In a place where compressed air does not spread, there is a problem that the peeling of the peeling is left and a complete peeling treatment cannot be performed. Further, when the long green onion is bent, the above-mentioned problem of the long green onion rising is also remarkable.

With respect to this problem, the skin shown in FIG.
Peeling machine70 on the left and right of the peeling position P.

71A ~71D and72A ~7For those with 2D
It is possible that But such a nozzle7
1,7In 2, supply pipe73A,7Pressure supplied from 3B
The amount of compressed air increases and the consumption of compressed air increases.
There was a problem that it would end up.

[0008] On the other hand, there is also known a peeling machine for peeling a long green onion surrounding the long green onion at four positions. In such a peeling machine, compressed air can be blown around the long green onion from four sides, and therefore the peeling efficiency was excellent. However, in this type of peeling machine, when setting the onion on the peeling position, it is necessary to insert the onion from the front side and move it in the longitudinal direction. In such an insertion method, since the moving distance of the long green onion becomes large, there is a problem that the workability is poor and the fatigue of the operator is also large.

Therefore, an object of the present invention is to allow compressed air to be blown to the whole green onion when performing the peeling treatment by blowing the compressed air of the green onion so that the whole green onion can be peeled off. To be able to do it. Another object of the present invention is to enable the skin peeling work of long green onions to be performed efficiently and to prevent the operator from feeling tired due to the skin peeling work.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 is an overall perspective view of an onion peeling machine according to a first embodiment of the present invention. As shown in FIG. 1, a peeling machine 1 according to the present invention has a pedestal 2 on which a long green onion N before being subjected to a peeling treatment is placed, and a peeling machine set on this pedestal 2 The peeling process is performed at the position P. Left and right nozzles 3 and 4 are provided on the left and right of the peeling position P on the pedestal 2 so as to blow compressed air onto the epidermis N to remove unnecessary matters.
Further, above the skin peeling position P, an upper nozzle 5 for removing unnecessary substances by blowing compressed air to the epidermis N is also arranged.

In the left nozzle 3, as shown in FIGS. 2 and 3, two cylindrical support members 3A, which are erected on the left side of the peeling position P of the onion N, are vertically separated from each other. The spouts 3B and 3C are attached. A screw groove (not shown) is cut in the support member 3A at a position below the ejection ports 3B and 3C. A portion of the support member 3A where the thread groove is cut is a long hole 2A formed in the mount 2.
And the left nozzle 3 is fixed to the gantry 2 by tightening the nut 3D in the thread groove.

Further, in the right nozzle 4, a cylindrical supporting member 4A which is erected on the right side of the peeling position P of the onion N.
Two ejection ports 4B and 4C that are vertically separated from each other are attached to the. In addition, the ejection port 4 in the support member 4A
A screw groove (not shown) is cut at a position below B and 4C. The portion of the support member 4A where the thread groove is cut passes through the elongated hole 2B formed in the pedestal 2, and the nut 4D is tightened in the thread groove to fix the right nozzle 4 to the gantry 2. There is.

As described above, since the left and right nozzles 3 and 4 are fixed by penetrating the long holes 2A and 2B, respectively, by tightening the left and right nozzles 3 and 4 at appropriate positions of the long holes 2A and 2B, respectively, The separation distance between the left and right nozzles 3 and 4 can be adjusted. Moreover, since the left nozzle 3 and the right nozzle 4 are rotatable around the support members 3A and 4A as shown in FIG. 3, the ejection angle of the compressed air can be adjusted.

Further, the upper nozzle 5 is, as shown in FIG.
It has a rectangular support member 5A, and two ejection nozzles 5B and 5C which are separated from each other in the left-right direction are attached to the support member 5A. From the ejection ports 3B, 3C, 4B, 4C, 5B, 5C in each of these nozzles 3, 4, 5, the horizontal direction along the surface of the gantry 2
Air is ejected in the depth direction of.

Further, as shown in FIG. 4, above the upper nozzle 5, an air cylinder 6 which is a nozzle retracting means of the present invention which can be moved up and down is arranged so as to retract the upper nozzle 5 from the skinning position. It is set up. The support member 5A of the upper nozzle 5 is attached to the tip (lower end) of the cylinder rod 6A of the air cylinder 6. Then, when the cylinder rod 6A extends, the upper nozzle 5 descends and is set to the skin peeling position P, and when the cylinder rod 6A contracts, the upper nozzle 5 rises and retracts from the skin peeling position. ing. The air cylinder 6 is adapted to adjust the length of the cylinder rod 6A when it is extended, and also has the height position adjusting means of the present invention for adjusting the height position of the upper nozzle 5 when it is lowered. I am configuring.

Further, the cylinder rod 6 of the air cylinder 6
An angle adjusting mechanism 7 serving as an angle adjusting means for adjusting the angle of the upper nozzle 5 about the horizontal axis is interposed between A and the upper nozzle 5. As shown in FIG. 5, the angle adjusting mechanism 7 includes a bracket 7A, and the bracket 7A includes
A block member 7C is rotatably supported by a rotary shaft 7B arranged along a horizontal axis. This block material 7
The support member 5A of the upper nozzle 5 is attached to C. By rotating the block member 7C around the rotating shaft 7B, the angle of the upper nozzle 5 about the horizontal axis can be adjusted.

Further, the peeling machine 1 is provided with a long green onion detection sensor 8 for detecting that the long green onion N is set at the peeling position P, slightly behind the peeling position P. As shown in FIGS. 2 and 3, the long green onion detection sensor 8 includes a light projecting section 8A.
The light emitted from the light projecting unit 8A reaches the light receiving unit 8B before the onion N is set to the peeling position P. On the other hand, when the long green onion N is set to the peeling position P, the light emitted from the light projecting unit 8A is blocked by the long green onion N and does not reach the light receiving unit 8B. In this way, when the light receiving unit 8B cannot receive the light from the light projecting unit 8A, it is detected that the long onion N is set at the skin peeling position P.

As shown in FIG. 2, each nozzle 3,
Supply pipes 9A, 9B and 9C for supplying compressed air from a compressor (not shown) are connected to 4 and 5. Further, as shown in FIG. 1, the peeling position P of the long onion N
A dust collecting net 10 is provided in the back of the dust collecting net 10 for collecting the wastes peeled off from the surface of the long onion N by compressed air.

The operation and action of the onion peeling machine 1 having the above construction will be described. Before performing the peeling work of the long onion N, the positions of the nozzles 3, 4, and 5 are determined. For the left and right nozzles 3 and 4, the distance between the two is finely adjusted based on the thickness of the long onion N to be stripped. Here, in order to reduce the ejection amount of compressed air when performing the skin peeling work,
The distance L1, between the nozzles 3, 4, 5 and the onion N shown in FIG.
It is preferable that L2 and L3 are short. However, since the onion N is an agricultural product and its thickness (size) is not constant,
If the distance between the left nozzle 3 and the right nozzle 4 is fixed,
When the long onion N to be peeled is changed, the width is not adjusted to an appropriate width. However, when peeling work of several long green onions N, N ... at one time, peeling work of long green onion N of almost constant thickness (size) is performed, and the left and right nozzles are used according to the thickness. Determine the positions of 3 and 4. When the positions of the left and right nozzles 3 and 4 are determined, a long onion N, which is a sample, is set at the skin peeling position P, as shown in FIG. The distances L1 and L2 between the left and right nozzles 3 and 4 and the onion N are within a range in which the left and right nozzles 3 and 4 and the onion N are less likely to collide when the worker places the onion N at the peeling position P. The distance between the left and right nozzles 3 and 4 is adjusted so as to shorten the distance.
When changing the position of the left nozzle 3, the nut 3D is loosened from the screw portion formed below the support member 3A, and the support member 3A is moved to an appropriate position along the long hole 2A formed in the pedestal 2. Then, the nut 3D may be tightened and fixed in the thread groove. In this way, the left and right nozzles 3,
The width between 4 can be adjusted. Further, if necessary, the left nozzle 3 can be rotated around the support member 3A to change the ejection direction of the compressed air ejected from the ejection ports 3B and 3C. Further, with respect to the right nozzle 4, the position of the right nozzle 4 and the ejection ports 4B and 4C are also subjected to the same work.
The ejection direction of the compressed air ejected from the can be changed.

After the positions of the left and right nozzles 3 and 4 are determined, the position of the upper nozzle 5 is subsequently determined. When determining the position of the upper nozzle 5, the cylinder rod 6 is moved by the air cylinder 6.
Adjust the length when A is stretched the most. Then, the distance L3 (FIG. 2) between the upper nozzle 5 and the onion N is adjusted within a range in which the upper nozzle 5 and the onion N set at the peeling position P do not collide. Further, if necessary, the angle adjusting mechanism 7 rotates the upper nozzle 5 around the rotating shaft 7B so that the ejection port 5
The direction of A and 5B can be changed.

When the positions of the nozzles 3, 4 and 5 are determined in this way, the peeling work of the onion N is started. At the stage when the peeling work of long green N begins, as shown in FIG. 6 (a),
The cylinder rod 6A of the air cylinder 6 is contracted,
The upper nozzle 5 is located at the top.

With the upper nozzle 5 in the uppermost position, the operator holds the leaf of the long onion N and inserts the long onion N from above between the left and right nozzles 3 and 4 to remove the long onion N. Set at the peeling position P. At this time, since the upper nozzle 5 is located at the uppermost position, the upper portion between the left and right nozzles 3 and 4 is open. The long green onion N is inserted from this opening and the long green onion N is set at the peeling position P. In this way, the left and right nozzles 3,
Since the onion N can be inserted between the four from above, the burden on the operator is reduced and the workability is excellent.

When the long onion N is set to the peeling position P,
The onion detection sensor 8 detects that the light emitted from the light projecting section 8A of the onion detection sensor 8 does not reach the light receiving section 8B and the onion N is set at the skin peeling position P. When it is detected that the long green onion N is set to the peeling position P, the air cylinder 6 automatically operates, and as shown in FIG.
The cylinder rod 6A extends. When the cylinder rod 6A extends, the upper nozzle 5 descends and moves to a position for peeling the long green onion N set at the peeling position P.

In this way, when the upper nozzle 5 is moved downward and the long green onion N set at the peeling position P is surrounded by the nozzles 3, 4, 5, a compressor (not shown) is activated to cause the nozzles 3, 4, 5 to move. Compressed air is supplied. At the same time, the worker pulls the long green onion N toward you. Nozzles 3,4
As shown in FIGS. 2 to 5, the compressed air supplied to No. 5 is ejected from the ejection ports 3B, 3C, 4B, 4C, 5B, 5C toward the onion N. This compressed air is blown onto the surface of the long onion N, and the unnecessary substances adhering to the surface of the long onion N are blown off to the dust collecting net 10 provided at the back. At this time, for long onion N, 3 in the left-right direction and in the upward direction.
Compressed air is blown from the direction. Therefore, it is possible to prevent the long onion N from floating upward, and it is possible to accurately blow the compressed air to the whole long onion N. Therefore, it is possible to reliably remove the unwanted matter attached to the surface of the long green N. In addition, since compressed air is jetted from the left, right, and upper three directions,
Compared with the prior to the skinning machine 61 shown in 4, skinning effect is increased, it is possible to increase the processing speed. Moreover, even if the jetting pressure of the compressed air is reduced, a similar peeling effect can be obtained, so that damage to the long onion N is reduced.

Further, if the upper nozzle 5 is simply provided above and fixed, the onion N cannot be inserted into the skin peeling position P from above between the left and right nozzles 3 and 4, for example, the left and right nozzle 3 , Onion N must be inserted from the front side between 4 and 4. In such a mode, the long onion N has to be largely moved, and the burden on the worker is increased. In this respect, the skin peeling device 1 according to the present embodiment is provided with the air cylinder 6 that retracts the upper nozzle 5 upward when the long onion N is placed at the skin peeling position P. Therefore, the worker can insert the long onion N into the skin-peeling position P from above. Therefore, the operator who carries out the peeling work can set the long onion N to the peeling position P by the same work as in the case of the conventional peeling machine without the upper nozzle 5, so that the burden on the worker is reduced. It does not increase.

When the operator continues to pull out the long green onion N and the compressed air is blown over the whole length of the long green onion N, the light emitted from the light projecting portion of the long green onion detection sensor 8 is not blocked and the light is emitted. It reaches the light receiving portion 8B. When the light from the light projecting section 8A reaches the light receiving section 8B, the compressor is stopped and the nozzles 3, 4 and 5 have the ejection ports 3B, 3
The ejection of compressed air from C, 4B, 4C, 5B, 5C stops. In this way, the peeling work of one long green onion N is completed.

When the work of stripping one long green onion N is completed, the air cylinder 6 is activated and the cylinder rod 6A contracts. As the cylinder rod 6A contracts, the upper nozzle 5
Rises and the upper portions of the left and right nozzles 3 and 4 are opened. On the other hand, the worker accommodates the long green onion N pulled out to the front in a storage unit (not shown) or the like, and starts the peeling work of the next long green onion N. In this way, the upper nozzle 5 is not provided in FIG.
Even in comparison with the prior of the skinning machine 6 1 shown, there is no possibility that the burden will increase to be applied to the worker. In this way, the peeling work of the long green onion is sequentially performed.

Next, a second embodiment of the present invention will be described. FIG. 7 is an overall perspective view of an onion peeling machine according to a second embodiment of the present invention, and FIG. 8 is a front view of relevant parts.
As shown in FIG. 7 and FIG. 8, the long onion peeling machine 11 according to the present embodiment includes a pedestal 12, and the pedestal 12 is formed with a groove 12A in which a peeling position P is set. There is. A left nozzle 13 and a right nozzle 14 are provided at left and right positions at the tip of the groove 12A. The left and right nozzles 13 and 14 have the same configuration as that of the first embodiment, and therefore detailed description thereof will be omitted. In addition, above the groove 12A, the groove 1
A cover 15 that covers 2A is provided, and an upper nozzle 16 is provided at the front end of the cover 15. Further, a cylinder 17 is provided above the cover 15, and the upper surface of the cover 15 is fixed to the tip end (lower end) of the cylinder rod 17A of the cylinder 17. And
When the cylinder 17 operates and the cylinder rod 17A expands and contracts, the upper nozzle 16 moves up and down via the cover 15. Now, when the cylinder rod 17A of the cylinder 17 extends, the concave groove 12A is covered by the cover 15, and the upper nozzle 16 is set to the peeling position P of the long onion N. On the contrary, when the cylinder rod 17A of the cylinder 17 contracts, the cover 15 moves up and the upper side of the groove 12A is opened.

Further, slightly behind the peeling position P,
An onion detection sensor 18 for detecting that the onion N is set at the peeling position P is provided. This onion detection sensor 18 has a light projecting section 18A and a light receiving section 18B, and has the same configuration as the onion detection sensor 8 in the first embodiment, so a detailed description thereof will be omitted.
A supply pipe 19A for supplying compressed air from a compressor (not shown) to each nozzle 13, 14, 16
19B is connected (the supply pipe connected to the upper nozzle 16 is not shown). Further, a dust collecting net 20 is provided in the back of the peeling position P of the long onion N for collecting the wastes that have been peeled off from the surface of the long onion N by the compressed air.

In the onion peeling machine 11 according to the second embodiment, an operator (not shown) manually carries the long onion N placed on the pedestal 12 to the peeling position P to remove the peeling position. Peeling is done at P. The procedure of this peeling process will be explained. Before the peeling work, the cylinder rod 17A of the cylinder 17 is contracted, and the cover 1
5 is rising. Therefore, the upper side of the groove 12A is in an open state. From this state, the operator holds the leaf part of the long green onion N by hand and inserts it from above the groove 12A to set it at the peeling position P. At this time, in the present embodiment, the upper part of the groove 12A is not yet covered with the cover 15, so that the long onion N can be inserted from above into the skin-peeling position P between the left and right nozzles 13 and 14. Therefore, the operator is not required to perform a troublesome work such as inserting the long green N from the front side, so that the burden on the operator does not increase.

When the long green onion N is set at the peeling position P in this way, the light emitted from the light projecting portion 18A to the light receiving portion 18B of the long green onion detecting sensor 18 is blocked by the long green onion N, and the long green onion N is removed. Detects that it has been set to the peeling position. When the long onion detection sensor 18 detects that the long green onion N has been set at the peeling position P, the cylinder 17 operates and the cylinder rod 17A extends. When the cylinder rod 17A is fully extended, the cover 15 covers the groove 12A. At the same time, a compressor (not shown) is activated to eject compressed air from the nozzles 13, 14, 16. The compressed air ejected from the nozzles 13, 14, 16 is blown onto the surface of the long green onion N, and unnecessary substances adhering to the surface of the long green onion are blown off toward the dust collecting net 20. In this way, the peeling treatment of the long onion N is performed.

In the present embodiment, compared to the first embodiment, when the long green onion N is set at the skin peeling position P and the skin peeling process is performed, the long green onion N has the concave groove 12A and the cover 1.
Covered by 5. Therefore, when compressed air is blown onto the long onion N, the surroundings become negative pressure, so that unnecessary substances adhering to the surface of the long onion N can be removed even if the pressure of the compressed air is further lowered. Moreover, it also exhibits a soundproof effect against noise generated during the peeling process.

Next, a third embodiment of the present invention will be described. FIG. 9 is a front view of a main part of an onion peeling machine according to a third embodiment of the present invention, and FIG. 10 is a circuit diagram showing the flow of compressed air. As shown in FIG. 9, the peeling machine 21 according to the present embodiment has a lower nozzle 23 provided below a peeling position P set on a base 22 similar to that of the first embodiment. Except for the above, it is almost the same as the first embodiment. The structure will be briefly described. Left and right nozzles 3 and 4 are erected on the left and right of the skin peeling position P,
An upper nozzle 5 is arranged above the skin peeling position P.
An air cylinder 6 is provided above the upper nozzle 5, and the cylinder rod 6 of the air cylinder 6 is provided.
An angle adjusting mechanism 7 is provided between A and the upper nozzle 5. On the far sides of the left and right nozzles 3 and 4 , there is provided an onion detection sensor 8 for detecting that the onion N is set at the skin peeling position. The long green onion detection sensor 8 has a light projecting portion 8A and a light receiving portion 8B. When the long green onion N is set to the peeling position P, the light from the light projecting section 8A does not reach the light receiving section 8B, and the light receiving section 8B cannot receive the light from the light projecting section 8, so that the long green onion N It is detected that it has been set.

Further, in the present embodiment, the lower nozzle 2

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. Hereinafter, modified examples of the present invention will be described. In each of the following modifications, the same members as those in the first embodiment or the second embodiment are designated by the same reference numerals and the description thereof will be omitted. FIG. 11 shows the first of the present invention.
It is a principal part side view which shows the modification of embodiment of FIG. In the peeling machine 31 according to this modified example, a swinging mechanism 32 is provided as the nozzle retracting means instead of the air cylinder 6. The swing mechanism 32 includes a swing arm 32A, and the upper nozzle 5 is fixed to the tip end of the swing arm 32A. Further, the pulley 32 is attached to the other end of the swing arm 32A.
B is attached. The pulley 32B is connected to the motor 32D via a belt 32C, and the pulley 32B is rotated via the belt 32C by driving the motor 32D. The swing operation of the pulley 32B causes the swing arm 32A to swing, whereby the upper nozzle 5 at the skin-peeling position P is retracted.

In this modification, the long onion N is connected to the left and right nozzles 3 and 4.
When it is set to the peeling position P between the rocking arms 32A, the swing arm 32A is raised so that the upper nozzle 5 is at the position indicated by the phantom line. Therefore, the long green onion N can be inserted from between the left and right nozzles 3 and 4 to set the long green onion N at the peeling position P. When the long green onion N is set at the skin peeling position P and the long green onion detection sensor (not shown) detects that the long green onion N is set at the skin peeling position P, the motor 32D operates. By the operation of the motor 32D, the pulley 32B rotates, the swing arm 32A swings, and the swing arm 32A and the upper nozzle 5 move to the position shown by the solid line. Then, the compressed air is ejected from the nozzles 3, 4, 5 to blow the compressed air to the epidermis of the long onion N, and the worker is
By pulling it toward you, the deposits on the surface are removed over the entire length of the long green N.

In this way, when the long onion N is completely pulled out from the peeling position P and the deposits on the surface are removed, the motor 32 is rotated so that the pulley 32B rotates in the opposite direction.
D works. Then, the pulley 32B rotates in the opposite direction and the swing arm 32A swings, so that the upper nozzle 5 is retracted to the position indicated by the phantom line. When the upper nozzle 5 is retracted, the next long green onion N is set at the peeling position P. After that, the skin peeling work is performed by going through the same procedure. In this modification, the upper nozzle 5 is retracted by swinging the swing arm 32A. Therefore, as compared with the first embodiment in which the upper nozzle 5 is retracted right above, the position for retracting the upper nozzle 5 can be set at a lower position, so that the entire peeling machine can be downsized. it can.

Next, a second modification of the first embodiment will be described. FIG. 12 is a main part front view showing a second modification of the first embodiment of the present invention. The peeling machine 41 according to the present modification is a cylinder 4 that serves as a retracting means of the present invention.
Have two. The cylinder 42 is provided with a cylinder rod 42A that expands and contracts in the horizontal direction. The upper nozzle 43 is fixed to the tip of the cylinder rod 42A. Similar to the upper nozzle 5 in the first embodiment, the upper nozzle 43 has a rectangular support member 43A, and the support member 43A has two ejection ports 43B that are separated from each other in the left and right directions.
43C is attached. The cylinder rod 42A is fixed to the support member 43A. The upper nozzle 43 is expanded and contracted by the cylinder rod 42A.
Is designed to move left and right. Further, the upper nozzle 43 is adjusted to be located above the skin-peeling position P when the cylinder rod 42A is most extended. Further, by contracting the cylinder rod 42A, the upper nozzle 43 moves to the left, and the upper nozzle 43 at the skinning position P retreats.

In the present modification, when the long green onion N is set at the skin peeling position P between the left and right nozzles 44, the cylinder rod 42A is contracted, and the upper nozzle 43 shows the skin as shown by the phantom line. It is located to the left of the padding position P. For this reason, since the upper part between the left and right nozzles 44 is open, it is possible to set the long onion N between the left and right nozzles 44 from above and set the peeling position P. When the long onion N is set to the peeling position P and the long onion detection sensors 8A and 8B detect that the long onion N is set to the peeling position P, the cylinder 42 is activated and the cylinder rod 42A is extended. . As it is, the cylinder rod 42A extends,
Eventually, the cylinder rod 42A expands most and the cylinder 4
2 stops. The cylinder rod 42A is the most extended,
When the upper nozzle 43 is positioned above the peeling position P as shown by the solid line, compressed air is ejected from the nozzles 44 and 43. Then, compressed air is blown to the skin of the long onion N, and the worker pulls out the long onion N to the front so that the long onion N
The surface deposits are removed over the entire length of the.

In this way, when the long green onion N is completely pulled out from the peeling position P and the deposits on the surface are removed, the cylinder 42 operates to contract the cylinder rod 42A. Then, by moving the upper nozzle 43 to the left, the upper nozzle 43 is retracted from the peeling position P. When the upper nozzle 43 is retracted in this way, the next green onion N is set at the peeling position P. After that, by going through the same procedure,
Peeling work is performed. In this modification, the upper nozzle 43 is moved horizontally to retract the upper nozzle 43 from the skinning position P. Therefore, as compared with the first embodiment, it is not necessary to move the upper nozzle 43 in the height direction, and energy loss can be suppressed.

Next, a modified example of the second embodiment will be described. 13A and 13B are front views showing a modified example of the second embodiment of the present invention, where FIG. 13A shows a state where the cover is opened and FIG. 13B shows a state where the cover is closed. FIG.
As shown in FIG.
A cover 52 for covering 2A is provided. The cover 52 is attached to the gantry 12 by a hinge 53 so as to be openable and closable. The cover 52 can be opened and closed around the hinge 53 by a drive mechanism (not shown). An upper nozzle 54 is attached to the back surface of the cover 52. The upper nozzle 54 is a rectangular support member 5.
4A, and the support member 54A is separated from the right and left 2
Two ejection ports 54B and 54C are attached. The support member 54A is fixed to the cover 52. Then, when the cover 52 is opened, the upper nozzle 54 retracts from the skinning position P.

In this modification, the long onion N is connected to the left and right nozzles 13,
When setting the peeling position P between 14
As shown in (a), the cover 52 is open and the upper nozzle 54 is in a retracted state. At this time, the left and right nozzles 1
Since the upper part of the peeling position P between 3 and 14 is open, the long onion N can be inserted from above between the left and right nozzles 13 and 14 to set the peeling position P. When the long green onion N is set at the peeling position P and the long green onion is detected by the long green onion detection sensor (not shown), the cover 52 is hinged by the drive mechanism (not shown) as shown in FIG. 13B.
3 is closed and the upper side of the groove 12A is covered by the cover 52. When the concave groove 12A is covered with the cover 52, the compressor (not shown) is activated, and the nozzle 13,
Compressed air is ejected from 14, 54 and the compressed air is blown to the long onion N at the skin peeling position P. At the same time, the worker pulls out the onion N to remove the deposits on the surface over the entire length of the onion N. In this modified example, as in the case of the second embodiment, the skinning position P is covered with the groove 12A and the cover 52. Therefore, when compressed air is blown onto the long onion N, a negative pressure is generated in the surroundings, so that unnecessary substances adhering to the surface of the long onion N can be removed even if the pressure of the compressed air is further reduced. Moreover, it also exhibits a soundproof effect against noise generated during the peeling process. Further, compared with the second embodiment, since the cover 52 is attached by the hinge 53 so as to be openable and closable, the moving distance of the upper nozzle 54 cover 52 can be reduced. Therefore, energy consumption can be reduced.

In addition to the above modifications, the upper nozzles are retracted in each of the above-described embodiments, but as a modification of the first embodiment, one or both of the left and right nozzles are retracted upward or downward. Can also be
Further, it is also possible to adopt a mode in which the worker moves the long green onion by using a carrying device or the like instead of moving the long green onion to the peeling position. Furthermore, for example, in the case of a peeling machine that covers a long green onion with a tubular case and performs peeling work with nozzles attached to the left and right and above the tip of the case,
Alternatively, the nozzle attached to the tip of the case may be retracted. This mode is an effective mode when, for example, a long-green leek is transported by a transport device and the case is moved in the longitudinal direction of the long-green onion and covered. When the case is moved, it is difficult to move the case if the nozzle protrudes from the case, but since the nozzle is movable, the case can be moved smoothly.
