[Detailed Description of the Invention] The present invention relates to a method and device for peeling onions, which enables quick and reliable peeling without damaging the onions, and further provides a simple and inexpensive structure. It is characterized by what it can do.

[Conventional technology]

Conventionally, this type of onion peeling device has been used to cut off a suitable upper part of the onion, make incisions in the surrounding skin, and then blow compressed air into these cuts and into the incisions to peel off the skin. provided.

[Problems to be solved by the invention] The above-mentioned conventional device uses a large compressor, etc., which makes the device large and expensive, the cost of use is high, and the freshness of the onion deteriorates due to damage around the onion. Moreover, the skin could not be peeled reliably, and the skin left on the lower part or around the area had to be removed manually, making it impossible to peel the skin efficiently.

Since the present invention can be constructed simply and compactly, it can be provided at an extremely low cost, and moreover, it can provide a quick and reliable peeling effect without damaging onions.

[Means for solving problems]

The present invention relates to a method and an apparatus for solving the above problems, and the invention includes a transfer belt that rotates in a transfer direction onions with the upper and lower protrusions cut off;
The device is characterized by being sandwiched between counter-rotating transfer belts that rotate in the opposite direction at a slower speed than the transfer belt, and the invention of this device is based on an onion extrusion rod provided at one end of the transfer path, an onion supply section and a transfer path provided in the onion supply section, a transfer belt provided on one side of the transfer path that rotates in the transfer direction, and a counter-rotating device that rotates in the opposite direction at a slower speed than the transfer belt at a required distance from the transfer belt. It is characterized by consisting of a transfer belt.

[Effect]

In the present invention, first, the upper and lower protrusions of the onion are cut off.

As will be described later, this is done by an automatic cutting section provided elsewhere in the device or by a cutting blade provided in a conveyance path for peeling.

As a result, the skin becomes rough from the fruit to the skin.

Then, they are pushed between a transfer belt that rotates in the transfer direction and a counter-rotating transfer belt that rotates in the opposite direction at a slower speed than the transfer belt and are transferred.

As a result, the onion, whose skin has become rough, is rotated between the belts and further transported forward, during which time the onion is rubbed and peeled by the belts.

Furthermore, by injecting air from above during the rotation and transfer, peeling becomes more reliable and the peeled skin is removed out of the transfer path.

〔Example〕

In FIGS. 1 to 4, the transfer path X is constructed on the upper surface 1 of the apparatus without being constructed with a special machine. That is, the front of the onion extrusion rod 2, which is provided at one end so as to be able to advance and return freely, is used as the onion supply section 3, and the front thereof is used as the transfer path X. In the figure, 4 is a cylinder for operating the extrusion rod 2.

Next, on one side of the transfer path X, there is provided a transfer belt 5 that rotates in the transfer direction.

This transfer belt 5 is constructed in two stages, upper and lower, and is tension-supported by pulleys 6 and 7, and has a cushion material 5a provided on its outer surface to enhance the clamping and frictional effects.

Further, a required distance is provided between the transfer belt 5 and the transfer belt 5.
A counter-rotating transfer belt 8 is provided which rotates counter-rotating at a slower speed than the transfer belt 5. This counter-rotating transfer belt 8 is also configured in two stages, upper and lower, is supported under tension by pulleys 9 and 10, and is made of a material having frictional force such as rubber. M in the figure each represents a motor.

In the illustrated embodiment, the lengths of the transfer belt 5 and the reverse rotation transfer belt 8 are made different, and the positions of the pulleys 6, 7 and pulleys 9, 10 are shifted.

This is to enable onions to be pushed and transferred between the transfer belt 5 and the counter-rotating transfer belt 8, regardless of their size.

That is, for example, if the pulleys 6 and 9 are fixed at the same position, it may be difficult to push a large onion depending on the fixed interval between them, or a small onion may not be held between the transfer belt 5 and the counter-rotating transfer belt 8. There may be cases where transportation is difficult.

In order to solve this problem, the distance between the transfer belt 5 and the counter-rotating transfer belt 8 should be made relatively narrow, one belt, specifically its pulley section, should be able to move freely outward against the spring. It is necessary to configure it so that it automatically returns to the position.

However, there is a drawback that the configuration is complicated.
Therefore, in the embodiment of the present invention, the pulleys 6 and 7 of the transfer belt 5 and the pulleys 9 and 7 of the reverse rotation transfer belt 8,
The position of belt 10 is shifted, and the interval between both belts 5 and 8 is configured to be such that a small onion can be held therebetween.

As a result, pulleys 6 and 7 of the transfer belt 5 are shortened when large onions are fed.
At this point, the onions are pushed toward the counter-rotating transfer belt 8, and the counter-rotating transfer belt 8 accepts the onions and bends, making it possible to pinch and transfer the onions easily and reliably.

Next, cutting off the upper and lower protrusions of the onion T will be described.

As shown in FIG. 4, the onion T has an upper protrusion a called a "cap" and a lower protrusion b consisting of a root.

Then, when the upper protruding part a and the lower protruding part b are cut off, the skin part becomes rough from the fruit part,
Peeling becomes extremely easy.

Therefore, in the present invention, an onion T with the upper protrusion a and the lower protrusion b cut off is prepared. These may be done manually, but in the embodiment shown, a separate cutting device is provided.

That is, circular holes 11 large enough to accommodate the upper and lower protrusions a and b of the onion T are provided at appropriate positions on the top plate 1, and a plate 13 having approximately the same size circular holes 12 on the top surface thereof is superimposed.

One end of the circular plate 13 is attached to the top plate 1 by a hinge 14, and the other end can be opened and closed.

Then, the upper surface plate 1 of the lower surface portion of the other end of the plate 13
A switch 15 is provided in the section, and a movable contact 15a of the switch 15 pushes up the other end of the plate 13 and is configured to maintain an electrically disconnected state at all times.

Further, a cutting blade 16 that advances and automatically returns to the lower surface of the circular hole 11 of the top plate 1 is provided, and is configured to advance and automatically return by operating the switch 15.

In the illustrated embodiment, the cutting blade 16 is configured to advance and automatically return using an air cylinder 17.

That is, when the switch 15 is connected, the air cylinder 17 is actuated via the solenoid valve 18, and the cutting blade 16 advances to the lower surface of the circular hole 11, and when the switch 15 is turned off, it automatically returns to its original position. However, it may be configured to automatically return even if the switch 15 is turned on after advancing.

In the case of the above embodiment, the switch 15
This operation can be carried out simply by fitting the upper or lower protruding part a or b of the onion T into the circular hole 12 of the plate 13 and pressing lightly.

That is, as shown in FIG. 4, if the upper and lower protrusions a and b of the onion T are sequentially fitted into the circular hole 12 of the plate 13 and pressed lightly, the plate 1
3, the movable contact 15a of the switch 15 is pressed and the switch 15 is connected, the solenoid valve 18 is switched, the cylinder 17 is activated, and the cutting blade 16 advances to the lower surface of the circular hole 11 and protrudes there. The upper or lower protrusion a or b is cut off.

FIG. 5 shows an example in which the cut-offs of the upper protrusion a and the lower protrusion b of the onion T are incorporated as lines.

That is, it is composed of a lower guide bar 19 and an upper guide bar 20, which are arranged in parallel with the onion T supply section 3 and the transfer path 2
2, and the onion T by the extrusion rod 2
The upper and lower protrusions a and b are removed during pushing.

In the figure, 23 and 24 are air injection nozzles provided above the transfer path X. That is, the injection nozzle 2
3 and 24 are provided with a slight inclination in the direction of the transfer path is removed from the transfer path X.

In the above configuration, in the embodiments of FIGS. 1 to 4, the onion T from which the upper and lower protrusions a and b have been removed is supplied to the supply section 3 by an appropriate method.

Next, the air cylinder 4 is activated, and the pushing rod 2 pushes it between the transfer belt 5 and the counter-rotating transfer belt 8.

As a result, the upper and lower protruding parts a and b have been removed, and the skin part of the onion T, which has a rough skin part from the fruit part, is rotated and transported by the transfer belt 5 and the counter-rotating transfer belt 8. It is rubbed and peeled off during the process.

Since the transfer belt 5 is rotated faster than the reverse rotation transfer belt 8, the transfer belt 5 is eventually transferred forward and sent to the next washing process or the like.

〔Effect of the invention〕

According to the present invention, it is possible to quickly and reliably peel onions without damaging them, and furthermore, the structure is simple and can be provided at low cost.
