Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method and device for peeling onions, which enables rapid and reliable peeling without damaging onions, and furthermore has a structure. It is characterized by the fact that it can be provided easily and at low cost.

[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.

[Problem that the invention seeks to solve]

The above-mentioned conventional equipment uses a large compressor, etc., which means that the equipment is large and expensive, the cost of use is high, and there are drawbacks such as damage to the area around the onion, which deteriorates its freshness. The skin was not peeled, and the skin left on the bottom or around it 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 of the method is to forcibly push an onion with the upper and lower protrusions cut off between clamping belts rotating in the opposite direction to the conveying direction, and then to adjust the speed of the onion. The invention of this device is characterized by feeding the onions between the transfer belts and transferring the onions. The present invention is characterized in that it consists of a clamping belt rotating in the opposite direction, and a transfer belt provided at a required interval in front of the clamping belt and having different speeds, with the extrusion rod's extension being the starting end of the transfer belt. It is something.

[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 forced between clamping belts rotating in the opposite direction to the transport direction.

As a result, the skin portion is rubbed by the clamping belt rotating in the opposite direction to the transport direction, causing cracks in the skin and further peeling.

Then, it is further fed between transfer belts having different speeds. As a result, the skin portion is completely peeled off and removed by the frictional force of the transfer belt.

Furthermore, if air is injected from above during the 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 top plate 1 of the apparatus without any special equipment.

That is, as shown in FIGS. 1 and 2, the front of the onion extrusion rod 2, which is provided at one end of the top plate 1 so as to be able to advance and return freely, is the onion supply section 3, and the front thereof is the transfer path X. There is.

4 in the figure is a cylinder for operating the extrusion rod. Next, in front of the transfer path X, holding belts 5, 5a are provided at a required interval and rotate in a direction opposite to the transfer direction.

In the case of the embodiment shown in the drawings, the clamping belts 5 and 5a are each constructed in two stages, upper and lower, and are tension-supported by pulleys 6, 7 and 6a, 7a, respectively. Further, in front of the clamping belts 5, 5a, there are conveyor belts 8, 8 having different speeds at appropriate intervals.
a is provided.

In the case of the embodiment shown in the drawings, the transfer belts 8, 8a are also configured in two stages, upper and lower, and pulleys 9, 10 and 9a, 1
The transfer belt 8 is tension-supported at 0a, and a cushion material k is provided on the outer surface of the transfer belt 8 to enhance the clamping and frictional effects.

The transfer belts 8 and 8a are rotated at different speeds in the transfer direction. That is,
The speeds of the transfer belts 8 and 8a are varied, with one rotating at a faster speed than the other.

Note that the clamping belts 5, 5a and the transfer belts 8, 8a are both structured in two stages, upper and lower.
Pulley 6, 6a, 7, 7a, 9, 9a, 10,
Each of the pulleys 10a may be made into a drum-shaped pulley, and a single elastic wide belt may be suspended thereon.

Further, in the present invention, the extension limit of the extrusion rod 2, that is, the maximum advancing position is set to the starting end of the transfer belts 8, 8a.

That is, the stroke is configured such that the onion is forcibly pushed between the holding belts 5, 5a which are rotating in the opposite direction, and the onion can be fed to the starting ends of the transfer belts 8, 8a.

In the embodiment shown in the drawings, the lengths of the belts provided on both sides, specifically the lengths of the clamping belt 5 (and transfer belt 8) and the clamping belt 5a (and transfer belt 8a) are different, and the lengths of the belts provided on both sides are different, and the lengths of the belts provided on both sides are different, and 6a, 7a and pulleys 9, 10, 9a, 1
The position of 0a is shifted so that they are not at the same position.

This is to enable onions to be pushed between the holding belts 5 and 5a and between the transfer belts 8 and 8a, regardless of their size, and to be able to be held and transferred without being pressed or soaked.

That is, for example, pulley 6 and pulley 6a,
If 7 and 7a, 9 and 9a, or 10 and 10a are fixed at the same position, the spacing between them will be limited and it will be difficult to push large onions, or small onions will be pushed into the holding belts 5 and 5a and the transfer belt 8.
and 8a, making it difficult to transport.

In order to solve this problem, the spacing between the clamping belts 5 and 5a and between the transfer belts 8 and 8a are made relatively narrow,
One of the belts, for example, the clamping belt 5a and the transfer belt 8a, must be able to move outwardly against a spring, and must also be constructed so that they automatically return to their original positions.

However, in that case, there is a drawback that the configuration is complicated. Therefore, in the embodiment of the present invention, pulleys 6 and 7 that support the clamping belt 5 and the transfer belt 8 are
and 9, 10, clamping belt 5a and transfer belt 8
Pulleys 6a, 7a and 9a, 10 supporting a
The position of a is shifted, and the spacing between the clamping belts 5 and 5a and the transfer belts 8 and 8a is configured to be such that a small onion can be clamped. As a result, when large onions are supplied, the belt on the opposite side of the pulley accepts the onions and bends, allowing the onions to be easily and reliably held and transferred without crushing them. be.

Note that FIGS. 1 and 2 show the pulleys 6, 7,
The only difference is the arrangement positions of 6a, 7a, 9, 10, 9a, and 10a, and everything else is exactly the same.

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, a circular hole 11 is provided at an appropriate position on the top plate 1, and is large enough to accommodate the upper and lower protrusions ab of the onion T.
A plate 13 having circular holes 12 of approximately the same size on its upper surface is superimposed.

One end of the same-shaped 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.

Furthermore, 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 a cylinder 17.

That is, when the switch 15 is connected, the cylinder 17 is actuated via the solenoid valve 18 and the cutting blade 1 is activated.
6 advances into the lower surface of the circular hole 11 and is configured to automatically return when the switch 15 is turned off.

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 can be operated simply by fitting the upper or lower protrusion 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, the switch 15 is connected, the solenoid valve 18 is switched, the cylinder 17 is operated, 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 and lower protrusions a and 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, the upper and lower protrusions a and b
The onion T from which the onions have been removed is supplied to the supply section 3. Next, the cylinder 4 is actuated to forcibly push the material between the clamping belts 5 and 5a which are being rotated by the extrusion rod 2 in the opposite direction to the transport direction.

As a result, the upper and lower protrusions a and b have been removed, and the skin of the onion is now in a rough state. Cracks occur and further delamination occurs.

Then, it is sent between the transfer belts 8, 8a which have different speeds, and the transfer belts 8, 8a
The skin part is completely peeled off by the frictional force of step (a) and is transported forward, and sent to the next washing process, etc.

Furthermore, during the above-mentioned transfer, if air is injected from the air injection nozzles 23 and 24 provided above,
The remaining skin is blown away, and the peeled skin is further removed to the outside of the transfer path X.

Since the transfer belt 8a is rotated faster than the transfer belt 8, it is eventually transferred forward and sent to the next washing process, etc.

〔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.
