Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a device for peeling green onions.

(Prior art) Conventionally, as a device for peeling long onions, the 14th
There was something like the one shown in the figure and Fig. 15.

This device consists of a machine frame 1, a green onion stand 2 made up of the top plate of this machine frame 1, a pair of air nozzles 3, 3 and a photoelectric tube 4 mounted on the green onion stand 2.
It is equipped with When green onion A is placed between the air nozzles 3, 3, the phototube 4 senses this, and air is injected from the air nozzles 3, 3 toward the green onion A.

Therefore, when using such a conventional device, first peel off some of the skin from the top of the green onion on the left side 2b of the green onion stand 2, and then set it between the air nozzles 3, 2a. The skin of the green onion was completely peeled by pulling the green onion A towards you (in the direction of arrow B in the figure) while blowing air from the part of the green onion A where the skin had been slightly peeled.

(Problem to be solved by the invention) However, the conventional device as described above has a problem in that the air nozzles 3, 3 are exposed to the outside, making a lot of noise. There was a problem that workers suffered from hearing loss.

In order to solve this problem, there is a soundproof cover that covers the leek mounting part 2a and the air nozzles 3, 3, but since the cover is separate from the top plate 2, there is no sound inside the cover. It is difficult to put green onions into the container and the workability is poor, and the current situation is that users who place importance on workability end up using the cover with the cover removed.

The purpose of the present invention is to solve the problems of the conventional apparatus as described above and to reduce noise without impairing workability.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides an opening/closing lid that covers the leek mounting portion and the air nozzle, a driving means for opening and closing the opening/closing lid, and an actuating means for operating the driving means. A detecting means is provided for detecting when the opening/closing lid is closed and injecting air from the air nozzle while the opening/closing lid is closed.

(Operations and Effects) Since the present invention has the above-mentioned configuration, it has the following operations and effects.

That is, first, a long onion is placed on the leek resting part with the opening/closing lid open, and then the actuating means is operated and the opening/closing lid is closed by the driving means.

When the opening/closing lid is closed, the detection means detects this and air is ejected from the air nozzle, allowing the skin of the green onion to be peeled.

Thereafter, the actuating means is operated again to open the opening/closing lid and the green onion can be taken out. When the opening/closing lid is opened, the detection means no longer detects the closed state of the opening/closing lid, and therefore, the air injection from the air nozzle automatically stops.

In this way, according to the present invention, the opening/closing lid and the air injection are linked, and when the opening/closing lid is closed, air is injected, and when the opening/closing lid is opened, the air injection is stopped, so that air is not injected. During this time, the part on which the leek is placed and the air nozzle are reliably covered by the opening/closing lid, which has the effect of reliably and significantly reducing the noise caused by the air jet sound.

In addition, when placing green onions on the green onion resting section, the opening/closing lid is open so that the green onions can be easily set.After peeling the skin, when taking out the green onions, the opening/closing lid can be opened and the green onions can be easily taken out. As a result, good workability can be obtained.

As described above, the present invention has the effect of reliably and significantly reducing noise without impairing workability.

(Example) The illustrated embodiment will be described below.

<First Embodiment> FIG. 1 is a schematic front view showing a first embodiment of a leek peeling device according to the present invention; FIG. 2 is a plan view of the same;
FIG. 3 is a left side view of the same as above, and FIG. 4 is a partially enlarged front view.

In this embodiment, an air cylinder is used as the driving means for opening and closing the lid, and a petal switch is used as the operating means. Further, a limit switch is used as a detection means.

Hereinafter, a detailed explanation will be given with reference to each of the above figures.

10 is the machine frame 1, and the top plate part is the leek stand 1
1 (hereinafter also referred to as the top plate).
The leek mounting table 11 is placed on the front side of the device (see Figure 2 C).
A groove 12 is formed extending from the rear side (see D in the figure). The bottom 13 of this groove 12
(See Fig. 4) constitutes the part on which the long onion is placed, that is, the part on which the leek is placed.

Reference numerals 20 and 20 indicate air injection nozzles attached above the leek mounting portion 13. The air injection nozzles 20, 20 are connected to an air introduction system 30, which will be described next.

The air introduction system 30 includes a filter unit 32 connected to an air compressor (not shown) via a pipe 31, a pressure gauge 33, a solenoid valve 34, and a branch pipe 35.

The air nozzles 20, 20 are connected to one of the branch pipes 35 by a pipe 35a.

36 is a solenoid valve interposed in the pipe 35a. The solenoid valve 36 and the solenoid valve 34 are each electrically connected to a control box 14 that controls the entire device.

Reference numeral 40 denotes an opening/closing lid, which covers the leek mounting portion 13 and the air nozzles 20, 20. This opening/closing lid 40 has an approximately semi-cylindrical lid main body 41.
and band-shaped rubber pieces 42 and 43 attached to the inner surfaces of both end edges of the lid main body 41. In the opening/closing lid 40, one edge of the lid main body 41 is located at the fourth edge.
As shown in the figure, it is rotatably attached to the top plate 11 of the machine frame with a hinge 44, and the air cylinder 45
It is designed to be driven to open and close. Lid body 41
A protruding piece 41b extending laterally is formed on the other edge. A limit switch 50 and a shock absorber 51 are attached to this protrusion 41b.

The shock absorber 51 is arranged between the lower edge of the lid body 41 and the top plate 11 to prevent the worker's hand from being accidentally caught between the lower edge of the lid body 41 and the top plate 11.
It is adjusted so that there is some distance (for example, about 10 mm) between the two.

The limit switch 50 is connected to the solenoid valve 36 of the air nozzle 20 via the control box 14. When the lid body 40 is closed, the solenoid valve 36 is turned on and opened.

The front surface of the opening/closing lid 40 is covered with a substantially semicircular plate 46. This plate 46 is made of transparent synthetic resin so that the condition of the green onions inside the lid can be visually observed. A lower edge 46a of this plate body 46,
The gap E that occurs between the onion mounting portion 13 is
Although it may be in an open state, in this embodiment, it is covered with rubber hanging pieces 47, 47 in order to enhance the soundproofing effect. There is a semicircular notch 46b in the lower center of the plate 46, and an outlet F for the green onion A is formed between the notch 46b and the hanging pieces 47, 47.

On the other hand, the back side of the opening/closing lid 40 is in an open state, and a discharge tube 48 is connected thereto as shown in FIG. Through this discharge tube 48, the peeled green onions are stored in a storage bag 49 made of a net material placed outside the work chamber G as described later.

The air cylinder 45 has a rod 45a whose tip is connected to a protrusion 41a of the machine frame 41.
The lower end of the cylinder 45b is rotatably supported by the machine frame 10. As shown in FIG. 1, the air cylinder 45 is connected to a branch pipe 35 of the air introduction system through a pipe 37. Then, normally, as shown by the imaginary line in FIG.
The state is such that 0 is left open. A solenoid valve 38 is interposed in the pipe 37 . This solenoid valve 38 is electrically connected to the control box 14.

52 is a pedal switch. The pedal switch 52 is connected to the solenoid valve 38 of the air cylinder 45 via the control box 14. Then, when the worker steps on the pedal switch 52, this pedal switch 52 turns ON and the solenoid valve 3
8, and the rod 4 of the air cylinder 45
5a protrudes to close the opening/closing lid 40.

Next, the operation of the device as described above will be explained.

(i) First, when the power of this device (not shown) is turned on, the solenoid valve 34 of the air introduction system 30 opens, the rod 45a of the air cylinder 45 is pulled, and the opening/closing lid 40 moves as shown in the imaginary line in FIG. It is in the open state as shown in .

(ii) Then, the operator stands on the front side of the device and sets the long green onion A, whose skin has been peeled to some extent in advance on the green onion table 11, on the green onion plate 13. Next, when the pedal switch 52 is stepped on, the solenoid valve 38
is activated, the rod 45a of the air cylinder protrudes, and the opening/closing lid 40 is closed.

Here, when placing the long green onion A on the green onion mounting portion 13, the open/close lid 40 is open, so that the green onion A can be easily set. Furthermore, since the leek mounting portion 13 is lower than the top plate 11, the air nozzle 20 does not get in the way and can be set smoothly.

Further, when the lid 40 is closed, the shock absorber 51 forms a space between the lower edge of the lid body 41 and the top plate 11, so that the operator can close the lid body 41.
There is no chance of getting your hand caught between the lower edge of the device 1 and the top plate 11 and getting injured.

(iii) When the opening/closing lid 40 is closed, the limit switch 5
0 turns on, the solenoid valve 36 opens, and the air nozzle 2
Air is injected towards the long leek A from 0 and 20.

Therefore, the worker can completely peel the skin of the green onion by pulling the green onion A towards him while blowing air from the part where the skin has been peeled to some extent in advance. The peeled skin passes through a discharge tube 48 and is stored in a storage bag 49.

Here, when air is injected, the opening/closing lid 40 is closed and the leek mounting portion 13 and the air nozzles 20, 20 are closed.
Since it is covered, the noise level is significantly lower. Moreover, in this embodiment, since the gap between the lid body 41 and the top plate 11 is closed with band-shaped rubber pieces 42, 43 and rubber hanging pieces 47, 47, the soundproofing effect is even more excellent.

(iv) After peeling the green onions, press pedal switch 5.
2, the solenoid valve 38 is activated and is pulled by the rod 45a of the air cylinder 45, opening the lid 40 as shown by the imaginary line in FIG. At the same time, the limit switch 50 is also turned off, the solenoid valve 36 is closed, and air injection from the air nozzle 20 is also stopped.

Here, the operator takes out the long onion A and places it in a predetermined place, but since the opening/closing 40 is open when taking out the long onion A, the worker can easily take it out.

With this, one cycle is completed, and the operator and the device repeat the operations (i) to (iv) above.

In the case of this embodiment, a pedal switch 52 is used as the operating means for the air cylinder 45.
Since it is not necessary to use one's hands to open and close the opening/closing lid 40 each time, one can use one's hands to perform tasks such as peeling green onions in advance, thereby improving work efficiency.
