Abstract

PURPOSE:To transport onions smoothly, by vibrating a conveyor path in a drainboard state slanting downward in the feed direction, rolling and sliding onions, blowing a high-pressure fluid for peeling on them in a counter flow. CONSTITUTION:Onions taken out from the feed hopper 2 are dropped on the conveyor path 3 in a drainboard state slanting downward in the feed direction, start to roll and slide by the slope and vibration by the vibrating motor 8 and the eccentric cylinder 6. In this process, a cut is formed on part of epidermis by the cut forming blade 24 set between the drainboard rods 31, the epidermis is eliminated by high-pressure air from the spray nozzle 15, the eliminated epidermis is dropped downward from the drainboard rods 31. Since onions are transported by the conveyor path in a drainboard state and a vibrator like this, onions are transported forcedly and smoothly, the epidermis is prevented from remaining without being peeled, and frequent cleaning caused by clogging is not required even if there may be rotten onions.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention 1 The present invention provides an apparatus 4 for peeling onions such as onions and garlic.
Regarding this.

[Technical background of the invention and its problems 1 Various devices of this type have been developed in the past. However, especially in the case of onions, there were problems in the transportation process, which will be described later.

The first method of transporting onions was developed in 1973-28.
No. 292 and Japanese Patent Publication No. 55-8352 using a roller conveyor, and the third one is Utility Model Application Publication No. 58-1018.
A third method is one using a roller conveyor as in Japanese Utility Model Application No. 51-80336, a method in which each piece is conveyed while being instructed by a needle, and a fourth is one in Japanese Utility Model Application No. 51-103.
There is a method using a partitioned conveyor as in Japanese Patent No. 097, and a fifth method as in Japanese Utility Model Publication No. 46-14794 in which the material is conveyed while being sandwiched between conveyor belts.

The ones that have been adopted as actual machines are (1) and (
This is method 2). However, if there are some rotten onions, they will stick to the screw blades or between the conveyor belts, impeding the normal conveyance of subsequent onions, and the peeled onions will stick to them, and the peeled onions will also stick to the onions. This results in residual adhesion, necessitating frequent cleaning.

(Objective of the Invention 1) An object of the present invention is to provide a conveying device for onions that can solve the above-mentioned problems and achieve smooth conveyance.

[Summary of the Invention] To achieve this object, the present invention includes a drainboard-like conveyance path that has a downward slope from an onion supply position to a discharge position and runs along the longitudinal direction, and vibrates this conveyance path to remove onions. The present invention is characterized by comprising a vibration device that promotes transfer and slipping, and a spray device that faces the conveyance path and sprays high-pressure peeling fluid toward the onions.

The first main point of the present invention is that the drainboard-like conveyance path is provided at an angle, unlike the conventional example. In contrast to the rotten onions that clog with a thread conveyor or a roller conveyor, the slatted conveyor path allows for smooth rolling and conveyance along the slatted boards. Another important point is that a vibration device is installed on the conveyance path to prevent rotten onions from accumulating due to transfers and slips.

[Specific examples of the invention] The present invention will be explained below using specific examples shown in the drawings.

Reference numeral 1 denotes a pedestal, at the bottom of which a collection container for skins, a control panel for each device, etc. are provided. Reference numeral 2 denotes an onion supply hopper, and a drainboard-like conveyance path 3 is provided below it. This conveyance path 3 includes end plates 30a, 30b, side plates 30c,
Longitudinal end plates 30a, 30b of a rectangular frame consisting of 30d
In between, a slatted rod (can be a board) along the longitudinal direction
31, 31, . . . The fists are arranged in the mountain direction at intervals, and the upstream end of the fists faces below the cutting opening 2a of the supply hopper 2. On the downstream side of the cutting opening 2a, an outflow control plate 4 is pivotally attached at its upper part. The control plate 4 regulates the amount of onions staying upstream of the conveyance path 3 falling downstream by its own weight, and controls the onions so that a constant amount of onions fall.

A bracket 5 having four arch-shaped retaining portions 5a is integrated with the end portion 30a of the conveyance path 3, and an eccentric tube 6 is engaged with the bracket 5. The shaft portion 6a of the eccentric cylinder 6 is supported by bearings 7A and 7B, and is rotated by the rotational force of a vibration motor 8 installed on a pedestal l via gears s, to, and ti. As a result, as the vibration motor 8 rotates, the eccentric tube 6 rotates eccentrically, so that the conveying path 3 vibrates vertically and backwards and forwards via the bracket 5. In the central part of the conveyance path 3,
It is installed on a support frame 12 and slides on this support frame 12 as the conveyance path 3 moves back and forth. Further, the conveyance path 3 is arranged with a downward slope from upstream to downstream, and the slope is adjusted by rotating an adjustment rod 13 with a handle screwed onto the pedestal l. The tip of the adjustment rod 13 is engaged with a long hole extending in the longitudinal direction of a protrusion 14 fixed to the support frame 12. On the other hand, spraying devices are disposed opposite to each other above the conveyance path 3 on the downstream side in order to peel off the skins of the onions rolling on the conveyance path 3. In the example shown in FIG. 1, this spraying device is equipped with a total of eight spraying nozzles 15 in two rows, four in one row, and these spraying nozzles 15 are attached to a holder I6. On three sides of the holder IB, a frame member 18 having a rail 17 in a direction perpendicular to the conveyance path 3 is provided astride the frame l.

A slider 19 is engaged with the rail 17, and the holder 18 is attached to this slider 19. The slider 18 has long holes 1111a and 1 along the top and bottom.
A fixing port 20.9a is formed and inserted through these.
20, the holder 16 is attached to the slider 18. The distance between the holder 16, in other words, the tip of the nozzle 15 and the onion On, is adjusted by loosening the fixing port 20 and lowering the holder 16 along the elongated hole 19a. ? A motor 21 is fixed, and a crank disk 22 provided on its output shaft and a slider 13 are connected by a link 23 with both ends pivotally connected. Therefore, when the motor 21 rotates now, the slider 19 reciprocates along the rail 17 as a result of the slider crank mechanism, and each nozzle 15 reciprocates in the transverse direction on the conveyance path 3. . In this process, high-pressure air and/or high-pressure water is injected from the nozzle 15 toward the onion On, and an operation is performed to peel the outer skin of the onion. The peeled onion On is discharged from the downstream end of the conveyance path 3 and is subjected to post-processing if necessary for use.

If the peeling with high pressure air etc. is not sufficient, the 5th
As shown in Figures 8 to 8, it is desirable to use a cutting device disposed upstream of the spraying device.

In the illustrated example, plate-shaped cutting blades 24, 24 are arranged between the drainboard rods 31, 31, and the connecting poles 25A, 25B, and spacers are straddled over the side plates 30c and 30d. It is configured to be fixed by a clamping plate 27 via 2B. The position of the cutting blade 24 is adjusted by moving it back and forth using the lower end inclined surface of the cutting blade 24, as shown in FIGS. 7 and 8.

In the peeling device configured as described above, when the onions cut from the supply hopper 2 are dropped onto the conveyance path 3, they are rotated due to the inclination and vibration caused by the rotation of the vibration motor 8 and the eccentric tube 6. The Douken slide begins. In this process, a cut is made in a part of the skin by the cutting blade 24, and then the skin is removed by high pressure air from the spray nozzle 15 or the like. The removed epidermis falls downward from between the drainboard bars 31.

Here, in the present invention, onions are transported using a drainboard-like transport path and a vibrating device, so even rotten onions are forcibly and smoothly transported, preventing them from clogging the transport path. Never.

[Effects of the Invention] As described above, according to the present invention, onions can be transported smoothly, and onions can be prevented from being left unpeeled. Further, there is no need to frequently clean the container due to clogged onions.
