Description

[Detailed description of the invention] [Field of industrial application] The present invention is a green onion peeling method in which compressed air or the like is blown onto the white roots of alliums to remove the skin of the white roots as well as dirt and other debris attached to the white roots. The present invention relates to a stripping device, and is particularly aimed at soundproofing the sound of a fluid such as air ejected from a nozzle from the outside.

[Conventional technology]

Conventionally, many devices have been proposed and put into practice for the purpose of peeling green onions by spraying a fluid such as compressed air and/or water onto the white root part of the green onions in the longitudinal direction.

For example, as shown in FIG.
One or more stages of air outlet 22 on one end side of 1
An air nozzle device 23 having an air nozzle device 23 is provided facing a point on an imaginary center line 24 corresponding to the position where the green onion to be peeled is placed, and the workbench 2
1, a guide plate 25 for guiding green onion skin and dirt blown away by compressed air to the side opposite to the air nozzle device 23 is erected oppositely, and a hook 26 straddles the left and right guide plates 25, 25. is engaged with the workbench 21 in the longitudinal direction of the guide plate 25 perpendicular to the air flow, and the opening of the garbage storage bag 27 is detachably fixed to the hook 26.

According to this device, a long onion to be peeled is placed on a workbench 21 along the imaginary center line 24 so that the air hits the white root of the onion, and after being pressed by hand, the air nozzle device 23 is operated by a pedal type valve or the like.
This device blows compressed air from the air outlet 22 of the spring onion to forcibly blow off the outer skin of the green onion and dirt such as dirt attached to it, thereby peeling the skin. There is no risk of lowering the product value, it is hygienic, and it is much more efficient than manual peeling.

[Problem that the invention attempts to solve]

When peeling green onions using the above device, the air and other fluids blown out from fluid nozzles such as air nozzles are mechanically compressed and ejected by a compressor, so the jetting noise is loud and there is a risk of noise pollution. It was also extremely unpleasant for the workers.

[Means for solving problems]

The inventor of the present invention has investigated various methods of soundproofing the sound of fluid blowing out of air or other fluids from fluid nozzles such as air nozzles, and has found that unpleasant noise can be efficiently blocked by using the sound-absorbing properties of polyurethane foam, etc. As a result of further studies based on this idea, the present invention was completed.

That is, the present invention is based on a workbench equipped with a fluid nozzle at one end for spraying a fluid onto the white roots of green onions to peel the skins of the green onions. A communicating guide plate is provided, and a housing cover covering the nozzle and the guide plate is hinged to be able to be opened and closed, and the inside of the cover is filled with a soft foam sound absorbing material whose surface is coated, and A cavity formed by the guide plate and the fluid flow path is penetrated in the spraying direction, and a peephole closed with a transparent plate is penetrated upward from the cavity, and an opening on the supply side of the onions of the cavity is penetrated. A transparent rubber sheet is provided vertically, a transparent eave is provided above the opening, and an open discharge pipe extending in the discharge direction is provided at the discharge side opening.

[Effect]

The purpose of using a soft sound absorbing material for soundproofing the sound of fluid injection as described above is to utilize its sound absorbing and sound insulating properties as well as to improve the adhesion to the workbench and block sound leakage. The purpose of covering the container so as to form an air flow path is not only to improve the soundproofing effect, but also to prevent the skins of the green onions blown off by the fluid from scattering and to ensure that they are carried in the same direction. Furthermore, the inner surface of the foam sound absorber was coated because the fluid blows away mud and dirt at the same time as the skin of the green onion, and some of it adheres to the inner surface of the sound absorber, making it necessary to clean the surface of the sound absorber. However, this is because it can be easily carried out by washing with water, etc., and this has the advantage of extending the service life of the foamed sound absorber.

Next, the reason why a peep hole is provided in the top plate of the housing cover from the cavity into which the leek is inserted is so that the worker can see the working status at a glance from the working position through the transparent plate attached to the hole.

In addition, the above-mentioned case cover is attached to the workbench with a hinge so that it can be opened and closed, but when cleaning the fluid flow path surface or the surface of the foam sound absorber on the workbench, the case cover can be tilted to easily clean the cleaning surface. This is to expose the

In addition, by providing a guide plate that communicates with the discharge open pipe along the direction of fluid spraying, it is possible to reduce the amount of blown green onion skin, dirt, etc. that is scattered from side to side within the cavity, and to prevent the inside of the foam sound absorber from scattering from side to side. There is less dirt and damage on the surface, and the life of the foam sound absorber is further extended. Furthermore, there is an advantage that the flow to these discharge ports becomes smooth and the soundproofing effect is also increased.

In addition, a transparent rubber sheet was placed vertically over the opening on the side of the supply port of the hollow green onions in order to effectively block sound leakage from the opening facing the worker. The purpose of this is to further suppress the leakage of unpleasant sounds toward the worker, and since it is transparent, it also has the advantage of allowing workers to clearly see where they are working. With this structure, there is no unpleasant noise directly transmitted to the worker from the opening, and the working environment is improved.

In addition, the open discharge pipe was extended to the discharge side opening of the cavity in order to ensure that the blown away skin and dirt were transported by air to the discharge location. Either can be used, so it is easy to use. Furthermore, by extending the open pipe in this manner, the soundproofing effect on the exhaust side is further improved.

〔Example〕

The present invention will be explained below with reference to embodiments shown in the drawings.

An air nozzle device 2 is provided at one end of the workbench 1 facing toward a point on the virtual center line 3 corresponding to the position where the long onion to be peeled is placed, and the skin of the long onion blown off by compressed air and A guide plate 6 is attached to guide dust and the like to a vinyl chloride pipe 5 fixed to a cutout in the side plate of the housing cover 4 on the side opposite to the air nozzle device 2. On the other hand, a coated flexible polyurethane foam sheet 9 having a cavity 7 that covers the air nozzle device 2 and the guide plate 6 and that opens downward and penetrates in the direction of air blowing, and a hole 8 that penetrates to the upper part and communicates with the cavity 7 is placed in a housing. It is installed inside the cover 4, and the side plate of the cover on the side of the air nozzle device 2 is cut out to serve as a leek insertion port 10, and a transparent acrylic plate 12 is attached to the through hole 8 of the upper plate 11 of the housing cover 4 to monitor the work status.

Insert the white root part into the air nozzle device 2 from 0, press it by hand, and operate the pedal type valve (not shown).
In the process of blowing compressed air toward both sides of the white root part of a long leek, the skin of the leek and the attached mud are smoothly air-transported to the PVC pipe 5 because the flow path through which they are blown away is narrowed by the guide plate 6. . Furthermore, the surface of the soft polyurethane foam sheet 9 becomes less dirty. Furthermore, by connecting an L-shaped PVC pipe to the PVC pipe 5 at any angle, the open pipe for discharge can be extended. Can be carried. At this time, the air nozzle device 2 and the sources of sound such as the white roots of the green onions that are hit by the compressed air are covered with a flexible polyurethane foam sheet 9 with a coating that has a high soundproofing effect.
Further, since the form sheet 9 has a case cover 4 installed therein tightly engaged with the work surface 15 by means of a hinge 16 and a snap lock 18, there is a gap between the work surface 15 and the case cover. There is also very little sound leaking out. Furthermore, a transparent rubber sheet 19 is hung from the top of the opening, which is the insertion opening 10 for the long leek a, to cover up the excess opening surface, and a transparent acrylic sheet eaves 20 is extended over the insertion opening 10 to improve the soundproofing effect. It is further improved.

Also, by opening the snap lock 18 and rotating the housing cover 14 about the hinge 16, cleaning the surface along the cavity 7 of the foam sheet 9, the guide plate 6, etc. to which peeled green onion skins, mud, etc. have adhered. parts can be easily exposed.

[Effect of idea]
