Description

  The present invention relates to a peeling processing machine for removing deposits such as old skin and soil adhering to the skins of vegetables such as long bean paste, leaf straw and leek.

When removing the deposits by blowing compressed air on the long skin, it is desirable to shorten the working time by blowing compressed air over a wide area of the skin.
In view of this, the skinning machine includes left and right nozzles that are erected on the left and right of the skinning processing position on which the eaves are arranged, and upper and lower nozzles that are provided above and below the skinning processing position. There is one in which compressed air is blown from the nozzle to the skin (see, for example, Patent Document 1).

Japanese Patent No. 2592339

  In the above-described conventional skin removal processing machine, compressed air is ejected linearly from nozzles, and since the spraying range of one nozzle is narrow, compressed air is sprayed onto the skin using a number of nozzles. Therefore, in the conventional peeling processing machine, since the flow volume of the compressed air used for the peeling process increases, there exists a problem that energy efficiency is low.

  Therefore, in the present invention, the above-mentioned problems can be solved, and vegetable deposits can be removed in a short time even if the flow rate of compressed air is small. Furthermore, even when the outside air temperature is low, compressed air is spread over a wide area of the epidermis. It is an object of the present invention to provide a peeling processing machine capable of spraying water.

  In order to solve the above-mentioned problems, the present invention is a peeling processing machine that blows compressed air from a nozzle to the skin of vegetables to remove deposits from vegetables, and the nozzle has a compressed air supply path. A formed support portion, a cylindrical nozzle cover having a rear end portion attached to the support portion, a tube inserted into the nozzle cover, and a rear end portion connected to a supply path of the support portion; The tube is formed of an elastic member, and the front end of the tube is moved along the inner peripheral surface of the nozzle cover by ejecting compressed air from the front end of the tube. A heating device for heating the tube is provided.

In this configuration, since the compressed air is blown onto the skin while rotating or reciprocating the front end portion of the tube, the blowing range of one nozzle can be expanded. Therefore, the number of nozzles necessary for the skinning process can be reduced.
Further, by rotating or reciprocating the front end portion of the tube, the compressed air does not concentrate on a part of the skin, so that the skin is hardly damaged even if the blowing force of the compressed air is increased.

  Note that when the temperature of the work space decreases and the tube becomes hard at low temperatures, the tube is difficult to rotate or reciprocate. In the present invention, since the tube can be warmed by the heating device, the flexibility of the tube can be maintained even when the temperature is lowered.

  Also, when the tube is made of urethane rubber, the urethane rubber is excellent in flexibility, so even if the total length of the tube is short and the outer diameter and inner diameter are increased, the front end of the tube can be smoothly rotated or moved. It can be reciprocated. Therefore, it is possible to reduce the size of the nozzle and increase the blowing force of the compressed air. Moreover, since urethane rubber is excellent in toughness, durability of the tube can be enhanced.

  In the above-described skinning processor, when the heating device includes a ventilation pipe for sending air into the nozzle cover, the air is forcibly sent into the nozzle cover. Since airflow is generated toward the front end opening, dust can be prevented from being sucked into the nozzle cover.

Furthermore, the heating device includes a blower and a heater that heats the blown air generated by the blower, and is configured to send the blown air generated by the blower into the nozzle cover through the ventilation pipe. Also good.
In this configuration, when the temperature of the work space is high and it is not necessary to warm the tube, the air generated by the blower can be supplied into the nozzle cover without operating the heater.

In the skinning processor of the present invention, vegetable deposits can be removed in a short time even if the flow rate of compressed air is small, and the energy efficiency of the skinning process can be increased.
In addition, since the tube can be warmed to maintain flexibility, the tube can be smoothly rotated or reciprocated.
Moreover, when it is configured to forcibly send air into the nozzle cover, dust can be prevented from being sucked into the nozzle cover.

Two nozzles 30 and 30 and a heating device 40 are mainly provided. A compressed air supply device (not shown) for supplying compressed air to the nozzles 30 is provided below the duct 10.

  The duct 10 is a container in which a bottom plate and left and right side plates are formed and front and rear end portions are open, and a root portion of the long wall N can be inserted from the upper opening portion 10a.

The nozzle support plate 20 is horizontally attached to the lower edge portion of the rear end opening 11 of the duct 10.
At the rear part of the nozzle support plate 20, two left and right mounting holes 21 and 21 are formed. The attachment hole 21 is a long hole extending in the left-right direction, and is a part to which the nozzle 30 is attached. Between the left and right mounting holes 21, 21, there is an area where the leaf portion of the long wall N is disposed.
In the nozzle support plate 20, circular insertion holes 22 and 22 are formed in front of the two mounting holes 21 and 21. The insertion hole 22 is a part through which a ventilation pipe 43 to be described later is inserted.

The two nozzles 30, 30 are installed in the left and right attachment holes 21, 21, and are erected on the nozzle support plate 20 with an interval in the left-right direction.
In addition, since the left and right nozzles 30 and 30 have the same configuration, one nozzle 30 will be described in detail in the following description.

  The nozzle 30 includes a support portion 31 whose lower end portion is attached to the attachment hole 21 of the nozzle support plate 20, a cylindrical nozzle cover 32 attached to the outer periphery of the support portion 31, and a cylindrical shape inserted into the nozzle cover 32. Tube 33.

  The lower end of the support portion 31 is attached to the attachment hole 21 with a bolt. On the outer peripheral surface of the upper end portion of the support portion 31, a mounting portion 31a having a circular cross section is provided so as to protrude in the horizontal direction. As shown in FIG. 3B, a fitting plug 31b is provided on the front end surface of the attachment portion 31a so that a rear end portion 33b of a tube 33 to be described later is externally fitted.

  As shown in FIG. 1, since the attachment hole 21 is a long hole extending in the left-right direction, the attachment position of the support portion 31 can be adjusted in the left-right direction within the attachment hole 21. Further, the orientation of the fitting plug 31b can be adjusted by rotating the support portion 31 about the vertical axis.

As shown in FIG. 2, a supply path 34 through which compressed air passes is formed in the support portion 31. The supply path 34 passes through the attachment portion 31a from the lower end portion of the support portion 31, and opens at the front end portion of the fitting plug 31b.
In the supply path 34, a supply hose (not shown) extended from a compressed air supply device (not shown) is connected to the lower end of the support portion 31. And it is comprised so that the compressed air supplied to the supply path 34 from the compressed air supply apparatus may eject from the front-end part of the fitting plug 31b.

The nozzle cover 32 is a cylindrical member made of metal, and protrudes in the horizontal direction from the outer peripheral surface of the support portion 31 by the rear end portion 32 b being fitted on the mounting portion 31 a of the support portion 31. Further, the front end portion 32a is expanded in a tapered shape (see FIG. 1).
In this embodiment, the nozzle cover 32 is formed of a metal material in consideration of the wear resistance of the nozzle cover 32. However, a hard resin material having excellent wear resistance may be used.

  At the rear portion of the nozzle cover 32, a cylindrical connecting portion 32d protrudes downward at a position in front of the mounting portion 31a. A communication hole 32e that penetrates from the lower end to the inner peripheral surface of the nozzle cover 32 is formed in the connection portion 32d.

  The tube 33 is inserted in the center position in the nozzle cover 32, and is formed of urethane rubber excellent in flexibility and toughness. The rear end portion 33 b of the tube 33 is fitted on the fitting plug 31 b, and the front end portion 33 a projects forward from the front end opening portion 32 c of the nozzle cover 32.

As shown in FIG. 3A, the inner diameter of the tube 33 is formed uniformly from the front end portion 33a to the rear end portion 33b, and the outer diameter of the tube 33 is larger in the rear end portion 33b than in the front end portion 33a. Is formed large. That is, the thickness of the rear end portion 33b is larger than the thickness of the front end portion 33a of the tube 33. The outer diameter of the tube 33 is increased in a taper shape from the front end portion 33a toward the rear end portion 33b.
For example, the tube 33 of the first embodiment has a total length of 90 mm, an inner diameter of 3 mm, an outer diameter of the front end portion 33a of 6 mm, and an outer diameter of the rear end portion 33b of 7 mm.

Urethane rubber is a polyurethane resin, and polyether-based and polyester-based resins exist. However, as the tube 33, polyester-based ester-based urethane rubber is used in consideration of mechanical properties and processability. preferable.
Moreover, the tube 33 can be stably rotated and moved from the low pressure range to the high pressure range of the compressed air pressure by increasing the durability by setting the hardness of the urethane rubber to 50 degrees. For example, the tube 33 can be stably rotated when the air pressure of the compressed air is in the range of about 0.2 to 0.6 MPa. Thus, since the range of the air pressure of compressed air is wide, the air pressure suitable for the skinning process can be selected.

  As shown in FIG. 3C, the rear end portion 33b of the tube 33 is externally fitted to the fitting plug 31b and is located at a position corresponding to the concave groove 31c formed in the circumferential direction of the outer circumferential surface of the fitting plug 31b. The binding band 33 c is fastened to the outer periphery of the tube 33. As a result, a part of the tube 33 enters the recessed groove 31c, and the rear end portion 33b of the tube 33 is firmly attached to the fitting plug 31b.

As shown in FIG. 2, a cylindrical collar 33 d is fitted on the tube 33 on the front end 33 a side of the intermediate portion.
The collar 33d is formed of a hard resin material having excellent wear resistance. As will be described later, the collar 33d slides on the inner peripheral surface of the nozzle cover 32 when the tube 33 rotates in the nozzle cover 32 (see FIG. 4A). 32 is prevented from contacting directly.
In this embodiment, the tube 33 is provided with the three collars 33d, but the number of collars 33d and their mounting positions are not limited.

  As shown in FIG. 1, the heating device 40 is disposed below the duct 10, and has a blower 41, a heater 42 that heats the air generated by the air blower 41, and a nozzle cover that blows the air generated by the air blower 41. And a ventilation pipe 43 for feeding into the interior 32.

The heater 42 includes a rectangular parallelepiped ventilation box 42a and a heating wire (not shown) accommodated in the internal space of the ventilation box 42a.
The heater 42 can heat the air in the ventilation box 42a by energizing the heating wire to generate heat. Energization of the heating wire can be turned ON / OFF by operating a switch provided on the outer surface of the ventilation box 42a.
The heater 42 is provided with a thermostat in order to stabilize the temperature in the ventilation box 42a and reduce power consumption.
An incombustible heat insulating material is affixed to the inner surface of the ventilation box 42a, and the power consumption of the heater 42 is reduced by enhancing the heat insulation effect in the ventilation box 42a.

  The blower 41 is a known device that discharges air from the exhaust port 41a by rotating a blade inside. The blower 41 is attached to the side surface of the ventilation box 42a, and the exhaust port 41a communicates with the lower part of the internal space of the ventilation box 42a.

  The ventilation pipe 43 is a hose having excellent heat insulation and flexibility. The ventilating pipe 43 is externally fitted to the connecting portions 32d and 32d (see FIG. 2) of the nozzles 30 and 30, so that two opening end portions communicating with the nozzle covers 32 and 32 and the ventilating box 42a are provided. And an open end communicating with the upper portion of the internal space. The ventilation pipe 43 communicates the internal space of the ventilation box 42 a with the inside of the nozzle covers 32, 32 of the nozzles 30, 30.

In the heating device 40, when air is sent from the exhaust port 41 a of the blower 41 to the internal space of the ventilation box 42 a, the ventilation is sent to the ventilation pipe 43 through the ventilation box 42 a. Further, as shown in FIG. 2, the air is sent into the nozzle cover 32 from the ventilation pipe 43 through the communication hole 32e of the connection portion 32d.
At this time, when a heating wire (not shown) of the heater 42 is heated, the air is warmed when passing through the ventilation box 42 a, and the hot air is sent into the nozzle cover 32.
For example, in the first embodiment, the heater 42 having a capacity of 200 W is set so that the inside of the nozzle cover 32 is about 40 ° C. when the outside air temperature is 5 ° C. In addition, since the heat retention effect in the ventilation box 42a is high, the power consumption for maintaining the set temperature is 0.1 kW per unit time.

Next, the peeling process of the long bag N using the peeling processor 1 will be described.
First, as shown in FIG. 1, the orientation of the nozzle cover 32 is set so that compressed air is ejected from the front end portion 33 a of the tube 33 toward the center in the left-right width direction obliquely rearward.
When the leaf portion of the long wall N is arranged between the two nozzles 30 and 30 and the root portion is put into the duct 10, a sensor (not shown) provided around the duct 10 is used to detect the long wall N and the operator. A hand is detected, and compressed air is sent to the support portion 31 from a compressed air supply device (not shown). Then, compressed air is ejected from the front end portion 33a of the tube 33 toward the skin.

As shown in FIGS. 4A and 4B, when compressed air is ejected from the front end portion 33 a of the tube 33, the tube 33 is bent, and the front end portion 33 a of the tube 33 is moved to the front end opening portion 32 c of the nozzle cover 32. It rotates along the inner peripheral surface of the.
In the nozzle 30 of the first embodiment, when compressed air is ejected at about 0.3 to 0.4 MPa, the tube 33 rotates at about 4000 revolutions per minute.

As described above, in the skinning processor 1 shown in FIG. 1, the front end portion 33a of the tube 33 rotates, so that the compressed air is spouted to the front of the nozzle 30 while being spirally spread and blown to the skin. Therefore, the spraying range of one nozzle 30 can be expanded, and the number of nozzles 30 required for the skinning process can be reduced.
Further, since the front end portion 33a of the tube 33 rotates, the compressed air does not concentrate on a part of the epidermis, so that the epidermis is hardly damaged even if the blowing force of the compressed air is increased.

  Therefore, in the skin removal processing machine 1, even if the flow rate of the compressed air is small, it is possible to remove the adhering material of the long length N in a short time, and the energy efficiency of the skinning process can be improved. For example, it can process at the flow volume of about 30% with respect to the flow volume of the compressed air used with the conventional peeling processor.

  Further, since the tube 33 is made of urethane rubber and the urethane rubber is excellent in flexibility, the front end portion 33a of the tube 33 can be smoothly rotated even if the overall length of the tube 33 is short and the outer diameter and inner diameter are large. Can be moved. Therefore, the nozzle 30 can be downsized and the compressed air blowing force can be increased. Moreover, since urethane rubber is excellent in toughness, durability of the tube 33 can be enhanced.

As shown in FIG. 4A, when the front end portion 33a of the tube 33 is rotated, the rear end portion 33b of the tube 33 is curved and the load on the rear end portion 33b is increased. Since the thickness of the end portion 33b is larger than the thickness of the front end portion 33a and the toughness of the rear end portion 33b is large, the durability of the tube 33 can be enhanced.
Further, the outer diameter of the tube 33 is increased in a taper shape from the front end portion 33a toward the rear end portion 33b, and no stepped portion is formed on the outer peripheral surface of the tube 33, so that the tube 33 is curved. Since it becomes easy, the tube 33 can be smoothly rotated and moved.

Here, the urethane rubber forming the tube 33 has a property of becoming hard at a low temperature. Specifically, when the temperature of the tube 33 is lowered to 10 ° C. or less, the tube 33 is difficult to rotate and move smoothly.
Therefore, when the air temperature in the work space decreases, the heater 42 shown in FIG. 1 is operated, the air generated by the blower 41 is heated by the heater 42, and hot air is supplied into the nozzle cover 32. In this way, the flexibility can be maintained by warming the tube 33.
In addition, when the temperature of the work space is high and the tube 33 does not need to be heated, the air generated by the blower 41 can be supplied into the nozzle cover 32 without operating the heater 42.

  As shown in FIG. 4A, since the air is forcibly sent into the nozzle cover 32, an air flow is generated in the nozzle cover 32 from the rear portion toward the front end opening portion 32c. It is possible to prevent dust from being sucked into the nozzle cover 32.

As mentioned above, although 1st embodiment of this invention was described, this invention is not limited to said 1st embodiment, In the range which does not deviate from the meaning, it can change suitably.
In the first embodiment, as shown in FIG. 1, the left and right nozzles 30 are provided, but the number and arrangement of the nozzles 30 are not limited. For example, an openable lid is provided on the upper surface of the duct. In addition to the left and right nozzles, compressed air may be blown onto the skin from the upper nozzle by providing a nozzle and a nozzle on the inner surface of the lid.

  Moreover, although the tube 33 is formed with urethane rubber, it can also be formed using various elastic members.

  Moreover, in the heating apparatus 40 of 1st embodiment, although comprised so that warm air may be sent in in the nozzle cover 32, the structure of a heating apparatus is not limited. For example, the tube 33 may be warmed from the inside by warming the compressed air fed into the supply path 34 of the support portion 31. Alternatively, the tube 33 in the nozzle cover 32 may be warmed by warming the outer surface of the nozzle cover 32 with a heater.

Moreover, you may comprise so that the attachment angle of the circumferential direction of the nozzle cover 32 with respect to the support part 31 can be changed freely. For example, when the nozzle cover 32 is attached to the support portion 31 by screwing a bolt inserted into the hole portion of the nozzle cover 32 into the screw hole of the attachment portion 31 a of the support portion 31, By forming a plurality of holes in the direction, the mounting angle in the circumferential direction of the nozzle cover 32 can be changed.
In this configuration, when a part of the opening edge portion of the nozzle cover 32 is worn away by contact with the long blade N, the nozzle cover 32 is rotated in the circumferential direction, so that the long blade N is formed in the worn portion. Further, contact can be prevented, and the useful life of the nozzle cover 32 can be extended.

  Moreover, in 1st embodiment, although the long bamboo basket is made into the object of a skinning process, the skinning processing of various vegetables, such as a leaf basket, a leek, an onion, can be performed with the same skinning processing machine.

<Second embodiment>
The skinning processor of the second embodiment has substantially the same configuration as the skinning processor 1 of the first embodiment (see FIG. 1), and the shape of the nozzle cover 35 is different as shown in FIG. ing.

  The nozzle cover 35 of the nozzle 30 </ b> A according to the second embodiment is formed in a long hole shape in which the front end opening 35 c extends in the vertical direction (vertical direction) with respect to the longitudinal direction of the nozzle cover 35. That is, the cross-sectional shape of the front end portion 35a is a long hole shape in which the left and right side portions are formed flat and the upper and lower portions are formed in a semicircular shape. The rear end portion 35b is formed in a cylindrical shape.

  In the nozzle 30 </ b> A, when compressed air is ejected from the front end portion 33 a of the tube 33, the tube 33 is curved in the nozzle cover 35, and the front end portion 33 a of the tube 33 extends in the vertical direction along the front end opening portion 35 c of the nozzle cover 35. Move back and forth.

In the skin peeling processing machine using this nozzle 30A, the tube 33 is reciprocally moved to blow the compressed air onto the skin, so that the spraying range of the nozzle 30A is widened and the skin is difficult to be damaged. Therefore, even if the flow rate of compressed air is small, long-sized deposits can be removed in a short time, and the energy efficiency of the skinning process can be improved.
Further, since the front end portion 33a of the tube 33 reciprocates linearly, the compressed air can be accurately blown against the skin, and the waste of the compressed air can be reduced.

  In the nozzle 30A, the front end opening 35c of the nozzle cover 35 is formed in a long hole shape, and the rear end portion 35b of the nozzle cover 35 is formed in a cylindrical shape so that the rear end portion 33b of the tube 33 is curved. The degree of freedom is increasing. Therefore, the load concerning the rear end portion 33b of the tube 33 can be reduced, the front end portion 33a of the tube 33 can be smoothly reciprocated, and the durability of the tube 33 can be enhanced.

  Moreover, in the peeling processing machine of 2nd embodiment, the tube 33 can be heated and a softness | flexibility can be maintained by supplying a warm air in the nozzle cover 35 from the heating apparatus 40. FIG. In addition, since air is forcibly sent into the nozzle cover 35, an air flow is generated in the nozzle cover 35, and thus dust can be prevented from being sucked into the nozzle cover 35. In the second embodiment, the configuration of the heating device is not limited.

  In the nozzle 30A of the second embodiment, the rear end portion 34b of the nozzle cover 35 is formed in a cylindrical shape, but the cross-sectional shape of the entire nozzle cover 35 may be formed in a long hole shape.
