Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic cutting adjustment structure of a base of an onion cutting device.

In other words, in an onion cutting device in which a disk-shaped stem cutter for cutting the onion stem is mounted on the upper part of a cutting passage through which the onion can be moved, the height of the onion cutting device may vary depending on the size of the onion. Even if the stems are different, the stem cutter can cut the stem equally well, and it can be adjusted automatically without manual intervention, and the cut can be made smoothly. The purpose of this invention is to provide a product that can be finished well and can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

A cutting passage A is formed in a straight line in the center of the case-shaped body B.
At one end of the cutting path A, an entrance 7 is formed into which the onions C can be placed upright, and at the other end of the cutting path A, an exit 8 is formed from which the flesh 1a of the onions C is discharged. At the lower part of the cutting path A, a lower groove 9 is formed over which the underside of the flesh 1a of the onions C straddles and into which the root 1c hangs. From the end of the lower groove 9 to the exit 8, a bottom surface 10 is formed with which the underside of the flesh 1a of the onions C comes into contact. At the upper part of the cutting path A, an upper groove 11 is formed through which the stem 1b of the onions C can pass, and guide grooves 13, 13 are formed on the outer surfaces of guides 12, 12 standing on both sides of the upper groove 11. A clip 14 in an inverted V shape capable of clamping the upper end of the stem 1b of the onion C inwardly has protrusions 14 on the inner surfaces of both lower ends that can fit into the guide grooves 13, 13.
a, 14a are formed respectively.

On both sides of the lower part in the middle of the cutting passage A, a disc-shaped two-plate root cutter 5a and a single-plate root cutter 5b are fitted to rotating shafts 15 and 16, respectively, and mounted on the shafts. The cutters 5a and 5b are installed so that the peripheral parts of the cutters 5a and 5b approach the bottom of the lower groove 9 and face each other. are mounted on a shaft, and large and small sprockets 17 and 18 are respectively fitted to the lower part of each rotating shaft 3a, 15, 3b, and 16, and a chain is wrapped around these so that the power can be transmitted by the motor M below. and configure.

A spline shaft 6 is attached to the upper part of both rotating shafts 3a and 3b.
A fitting body 19a, which is spline-fitted to both spline shafts 6 and can move up and down, respectively.
The center portions of the disc-shaped stem cutters 2a, 2b are respectively fixed to 19b, so that the peripheral portions of the two cutters 2a, 2b, which are close to each other so as to mesh with each other, are close to the bottom of the upper groove 11 and face. installed, both fitting bodies 19
Collars 20a, 20 in contact with the lower surfaces of a, 19b
Rigid sensors 4a and 4b, which are loosely fitted into rotating shafts 3a and 3b respectively and extend integrally from both collars 20a and 20b, slide on the bottom surface 10 to move in the cutting path A. Compression springs 22, 22 are installed between the stoppers 21, 21, which are attached to the upper parts of the rotating shafts 3a, 3b, and the fitting bodies 19a, 19b, so as to be able to contact the upper side of the real part 1a of the C, respectively. Fit each into the rotating shaft 3
A stopper 23 locked near the bottom of a, 3b,
23 and the collars 20a, 20b are provided with a compression spring 2.
4 and 24 respectively, and the sensors 4a and 4b
The cutters 2a and 2b are both installed so that they can move up and down.

A conveyor belt 27 is wound around a pulley 25 fitted to a lower intermediate portion of the rotating shaft 3a and a pulley 26 mounted on a side near the inlet 7,
Projections 28 are provided at regular intervals on the outer periphery of the conveyor belt 27 so as to protrude into the middle side of the cutting path A to support the fruit part 1a of the onion C. A stopper rod 29 is erected on the side, and the projecting piece 28 is installed and configured so as to rotate while being bent against the stopper rod 29 so as not to rotate within the entrance 7.

Therefore, during work, the root cutter 5a,
5b is the stem cutter 2 as shown by arrows A and B.
a and 2b rotate as shown by arrows C and D, and the conveyor belt 27 rotates as shown by arrow H, but the projecting piece 28 of the conveyor belt 27 enters the cutting path A from the inlet 7 side. In this state, as shown by the imaginary line in FIG. 4, it comes into contact with the stop rod 29 and bends, avoiding the inside of the entrance 7, and rotates into the cutting path A, so that it is in an upright position. When onions C are fed into the inlet 7 as shown by the arrow, they can be fed without being repelled by the protrusion 28.

The onion C entering the cutting passage A from the entrance 7 is pushed back by the projection 28 with the root 1c hanging down from the lower groove 9 and the stem 1b passing through the upper groove 11, as shown in FIG. However, insert the upper end of the stem 1b that protrudes above the upper groove 11 into the inside of the clip 14, and while grasping the stem 1b by pinching the upper part of the clip 14 with your fingers, press both protrusions of the clip 14. 14a, 14a can be slid along the guides 12, 12, and the onion C can be moved without exposing the fingers to danger.

When the onion C is fed and moved into the cutting path A in this manner, the root portion 1c is first cut and excised using the cutters 5a and 5b for both roots as shown in FIG. As shown, the stem part 1b is cut and removed from the lower part by the stem cutters 2a and 2b, and the fruit part 1a is directly discharged from the outlet 8, but the onion C has its root part 1c cut off and the stem part 1b is removed by the stem cutter 2a. , 2b, as shown in FIGS. 3 and 7, both sensors 4a and 4b come into contact with the upper side of the fruit part 1a of the onion C, and the fruit is separated by the size of the onion C. Part 1a
The sensors 4a and 4b move upward according to the height of the onion C, and at the same time, as the collars 20a and 20b move upward, the stem cutters 2a and 2b also move upward, and the size of the onion C increases. Different stem part 1
b will be excised in the same way.

As described above, the present invention provides an onion cutting device in which a disk-shaped stem cutter for cutting the onion stem is mounted on the upper part of the cutting passage through which the onion can be moved. The cutter is spline-fitted to the vertical axis of rotation so that it can move up and down, and a sensor that can move up and down along with the stem cutter is extended so that it can come into contact with the onion, so its height can be adjusted depending on the size of the onion. Even if the onion stems are different, a sensor that can touch the onion fruit detects its height and automatically moves the stem cutter up and down, making it possible to cut the stems of each onion equally well. It has the advantage that the stem can be cut smoothly without manual intervention while automatically adjusting well, and that it can be finished well for shipping and can be carried out suitably.
