Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a peeling device for removing the outer skin of onions.

[Technical background of the invention and its problems]

Onions are eaten after removing the outer skin and the entire upper F part. In food factories that handle large quantities of onions, it takes a lot of effort to peel onions with a knife, so techniques such as Japanese Patent Application Laid-Open No. 33843/1973 have been proposed. However, the reality is that with this type of product, it is practically impossible to completely remove the skin reliably, and some human assistance is required.

[Purpose of the invention]

FuhazuJ has developed an onion peeling device that can reliably perform complete peeling and also has a simplified device configuration.
1 Serve 7. ).

[Shelf of inventions, cheap]

In order to achieve this goal 1-1, the present invention provides a conveyance device that conveys onions individually, and an incision that makes an almost circular cut in the upper part of the onion mainly through only the outer skin in a plan view during the conveyance process. All 1 high-pressure air is applied from 10 people to the device and the incision part of the outer skin downstream of it! ? The present invention is characterized in that it is equipped with a device for peeling R (which causes T tripping).

By the way, the above-mentioned publication teaches how to make incisions all over the outer skin of an onion and blow it away with high-pressure air VC, but in order to deal with this inaccuracy, the present invention (bow 1 In the first place, the outer skin has a direction from the bottom to the top, so a circular cut is made in the top part in plan view, and the outer skin is peeled off by a jet of high-pressure air from the cut point. This is what we are trying to remove.

[Specific examples of the invention]

Hereinafter, the present invention will be explained in more detail using an example of J-18 shown in the drawings.

FIG. 1 is a schematic plan view showing the overall relationship, and ``■'' is the first conveyor, which is connected to the second conveyor 3 via the tube 1-2. As shown in detail in FIG. 2, on the board 5, which is installed across the chain links 4, 4 of the first conveyance comparator I, there are two receiving tubes 6 on the left and right sides (with respect to the line).
. The receiver tubes 6 are arranged at intervals in the running direction with an appropriate pitch.
Two conveyor lines, left and right, are configured.

Above the first conveyor 1, an upstream cutting device X is installed.
A peeling device Y is arranged downstream.

Details of the cutting device X are shown in FIGS. 2 and 6. Reference numeral 7 designates a board, into which a bearing 8 attached to one end is fitted with a guide rod 9 erected on a base (not shown), and the other end is fitted with a guide rod 9 erected on the base. Rod l'O of Linda 10
By being connected to a, a pedestal that straddles the first conveyor l is configured. A rack 12 integrated with the rod of a double-acting rotary leader 11 is mounted on the board 7''.
, and a pair of left and right annular binions 13 that mesh with the binions.
13 are provided. The annular pinion 13i17i is integrated 11 with the rotary cylinder J5 into which the operating rod 14 is inserted. A vertical hole 15a is formed in the rotary cylinder 15, into which a pin 16 integrally projecting from the operating rod 4 is fitted. The lower end of the operating rod 14 is integrated with a cut tube 17 that opens in the F direction, and the cut tube 17 and the rotary tube 1 are connected to each other.
A spring 18 is interposed between the spring 18 and the overhang 15α of the spring 5. Cutting blades 19 are protruded from the lower end of the notch tube 17 at four locations at 90-degree intervals in the circumferential direction, and inside the notch tube 17 are an air supply chamber 17A and a discharge chamber that communicate with the hose port 17a. 17
A partition part 17c that partitions B with a small hole 1'7b.
is formed. Hose port l 7 a, is 3 in the circumferential direction
It is privately owned and connected to the surge tank and compressor via a hose 20'.

In such a device, onions are manually or mechanically placed on the receiving tube 6 of the first conveyor l that moves intermittently.
11 Load the f. When the conveyor 1 moves in this state and the ball Qn reaches the lower position of the cutting device X, the conveyor 1 stops for 6 to 4 seconds. Immediately after stopping, the elevator 7 cylinder 10 is activated, the base plate 7 is lowered, and the rotary cylinder 15, operating rod 14, and cutting cylinder 17 are also lowered.

Before this descent, the cutting cylinder 17 is in a state separated from the onion On by a distance, and as it descends, it comes into contact with the upper part of the onion Qn. The stroke of the lifting/lowering cylinder lO is larger than the distance range 1t9, and when the F drop exceeds the separation pressure 1liIlt, the abutting notch cylinder 17 acts as a seat and the spring 18 is moved along the operating rod 14. Against the forces of
Only the rotary cylinder 17 slides down. As a result, the spring 18 is compressed, and the cutting tube 17 is pressed toward the onion On. During or after this pressing process, the rotary cylinder 11 is operated, and the rotary cylinder 15 is rotated via the rack 12 and the pinion 13. As a result, Bin 1
6ff: The operation rod 14 and the cutting tube 17 rotate through the cutting blade 19, and a circular cut C is formed in the upper part of the onion On only in the outer skin part i in a plan view.

Here, the shape of the cut C may not be circular but may be polygonal. Further, in forming the cut C, it is possible to form the cut C only by suppressing the cut cylinder 17 without rotation, but it is smoother to apply a rotational force.

The support blade 6a of the receiver cylinder 6 prevents co-rotation during the formation of the cut.

When the cut is completed, the rotation/cylinder 11f''i is operated in reverse to reverse the cutting cylinder 17, and at the same time, the lifting cylinder 10 is also operated in reverse to raise the cutting cylinder 17f.

In this step 11, the pressure blown from the hose 20 is blown out from the small hole 17b, and it remains on the receiving tube 6 at the surface of the onion, which rises together with the cutting part 17. By reversing the reno predicate J7, the formation of the notch C and the R with the 1st incision Qn
Cutting is ensured.

After that, it is placed on the receiving tube 6 and the ball is turned on. 1] Release device Yi
transported by The printing part device Y is basically almost the same as the cutting device The difference is that the cylinder 21 has been removed, the high-pressure air reaches the inner metal hole 9 of the rotating cylinder 22, the jet 11 that comes out from the bottom, and the J-spaces 23, 23. The injection hoses 23, 23+ are fixed to the housing by means of a fixing fitting 24. In addition,
RF! l1 distance 1
411 (see Figure 8).

Thus, when the onion On reaches the bottom of the peeling device Y,
The lift/linder operates and the peeling cylinder 21 descends (7th
figure). At the lower limit position, high-pressure air is injected from the injection hose 23, and at 11':i, the rotation/ring operation causes the peeling cylinder to repeatedly rotate forward and reverse every 180 degrees around its axis. As a result, the high-pressure air ejected from the injection hose 23 is intensively injected into the notch C, and as shown in FIG. 8, the outer skin is mainly peeled off. When this peeling operation is finished, the peeling cylinder 21 moves up and retreats, and the onion is turned to the second
It is transferred to the transport conveyor 3.

The second conveyor 3 has spokes 3 between the chain links.
During this conveyance process, the outer skin that has not been partially peeled 11 in the previous operation is finally removed. This final skin removal device Z has a structure shown in FIGS. 9 to 16. That is, a movable table 33 is provided on support shafts 32 at the front and rear in the line direction, spanning between the bearings 31 of both T! .Both fil!l K of the moving table 33
