DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slit cutter device in an automatic onion peeling machine for making a plurality of slits in the onion skin as a pretreatment when automatically peeling the onion skin.

[0002]

2. Description of the Related Art Conventionally, as an apparatus for automatically removing the skin of an onion, an onion root and a bud core are cut off, and then the onion is rolled on a rotating roller, and compressed air is blown against this. Those that remove the skin are known.

[0003]

However, according to the above-mentioned conventional method, the outer skin is not sufficiently removed and a lot of residue is left, and these are eventually peeled off by hand. The present invention has found that the skin can be completely removed by putting a plurality of slits extending in the longitudinal direction in the skin of the onion as a pretreatment, and it has made it possible to accurately slit only the skin of the onion. It is an object to provide a slit cutter device.

[0004]

According to the present invention, as a means for achieving the above-mentioned object, there is provided an elevating shaft which moves up and down toward an onion just above an onion which is placed on a table in an inverted state; A plurality of arm plates fixed to the arm plate, a cutter arm which is attached to the arm plate so as to be openable and closable and has a slit cutter at a lower end portion and is constantly urged in the onion direction by the elasticity of a spring, The cutter arm descends as the elevating shaft descends, and a plurality of slits are formed in the outer skin of the onion by the slit cutter of the cutter arm.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The concrete structure of the present invention will be described with reference to the drawings. The table 1 for supporting an onion a in an inverted state is appropriately set so that a bud core b of an onion protrudes downward. The bud core b portion projects downward from the hole 1a, and this protruding portion (bud b) is cut off by the slide cutter 2 installed below. . An elevating shaft 4 that moves up and down in the direction of the onion a by an air cylinder 6 is installed directly above the onion a, and the upper end of the cutter arm 6 is attached to the four The cutter arm 6 can be opened and closed with the shaft 7 as a fulcrum. The lower end of the cutter arm 6 is formed in a round shape, and a slit cutter 8 is exchangeably mounted on this portion with a screw 9. And
The cutter arm 6 has a pin 10 implanted in an upper outer shoulder 6a. The upper end of the pin 10 engages with the cut groove 5a provided in the arm plate 5, and the spring 11 is wound. The elasticity of the lever spring 11 constantly urges the cutter arm 6 in the direction of the onion a.

Next, a rotary conical blade 12 for removing the root c of the onion is attached to the elevating shaft 4, and the shaft 12a of the conical blade 12 penetrates through the elevating shaft 4 and the upper end has the conical blade 12 at its upper end. There is a small motor 13 for driving, and a cam disc 14 is rotatably mounted on the outside of the elevating shaft 4 so as to bias the spring 16 through a through hole 5b formed in the arm plate 5. A receiving pin 15 is interposed between the protruding piece 6b of the cutter arm 6 and the cam disc 14, and the cam disc 14 is rotated by a handle 17 attached to the cam disc 14 to form a cam surface 14a.
Can change the degree of opening and closing of the cutter arm 6, that is, adjust the opening and closing of the cutter arm 6 according to the size of the onion.

According to the present invention, the onion a is placed on the table 1 in an inverted state, and the holding plate 18 having a circular hole 18a in the center.
Is manually turned forward to hold the upper part of the onion, and then the elevating shaft 4 is lowered. When the slit cutter 8 comes into contact with the onion outer skin, four slits d are formed in the vertical direction of the outer skin.
At approximately the same time as this operation, the rotary cone blade 12 removes the root c of the onion a, and the slide cutter 2 cuts off the bud b. At the end of this operation, the table 1 is turned downward. The onion a falls to a predetermined position, and the outer skin is removed by the compressed air and the rotating roller.

[0008]

According to the present invention, since the cutter arm 6 is constantly urged inward, that is, in the direction of the onion a, by the elasticity of the spring 11, the slit cutter 8 mounted on the lower end of the cutter arm 6 has an appropriate size. It slides on the outer periphery of the onion under pressure, and when the elevating shaft 4 descends, the cutter arm 6 also descends at the same time, and the vertical slit d enters the outer skin of the onion accurately and at an appropriate depth, so that the pre-treatment for peeling the outer skin is surely performed. When the slit cutter 8 becomes dull, it can be easily replaced with a new slit cutter. As described above, the present invention makes it possible to reliably insert a plurality of slits in the onion skin,
This has the effect of completely removing the outer skin without leaving the outer skin of the onion in the outer skin peeling step.
