Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a peeling removal device for a green onion skin peeler, which can accurately peel and remove the skin of a green onion.

When shipping harvested green onions to the market, the process of peeling off the aged and inedible withered skin that covers the surface of the white root has been replaced by manual labor and has been automated in recent years, but the process of peeling off the aged and inedible epidermis that covers the surface of the white root has been replaced by manual labor. There are various problems in mechanizing this process of peeling and removing the epidermis, and the reality is that no satisfactory practical product has yet been completed.

Conventional methods for mechanizing this process involve jetting a pressurized fluid such as water or air from a jet nozzle, causing it to collide with the white root of the green onion, and peeling off the skin by the impact effect. Alternatively, a method has been proposed in which the epidermis is peeled off by the above-mentioned method, and a peeling device consisting of a pair of belts or sponge rolls is attached, thereby completing the peeling and removal of the epidermis. ing.

However, in the case of the former method, the process from ablation to removal of the epidermis is carried out using only jetted fluid, so a large-capacity pressurizing pump is required, and the power source and accompanying equipment must also be able to withstand high pressure. In addition, since the onion itself is exposed to high-pressure fluid for a long time, the white root part is damaged and the product value decreases. It is.

On the other hand, the latter method mainly uses pressurized fluid to peel off the epidermis, and then uses a peeling device such as a roll to hold the hanging skin and mechanically peel it off. Because it is used in combination, it is possible to use a relatively small-capacity, low-pressure pump without the need for a high-pressure pump, making the device more compact and easier to handle, and reducing the risk of damaging onions. It has no advantages. However, in this device, since the removal device is configured to forcibly pull the epidermis downward using a belt or roll, it may be difficult to properly and securely clamp the epidermis, or even if the epidermis is clamped, Also, since the forced tension time becomes longer,
By the time the epidermis was removed, the stems and leaves of the green onion were defective, causing troubles such as deviating from the conveying device that grips and conveying them, being crushed between the rolls, and clogging the conveyance. This is especially true when the epidermis of green onions is removed even though the root hairs remain, as the rolls often pull on the root hairs, making it even more likely to cause trouble, making it impossible to put it into practical use. Furthermore, the injected fluid collides with the lower roll with force, but at this time, in the case of conventional equipment, the injected fluid carries skin debris and mud.
Since it rebounded or stagnated in this area, skin debris and mud polluted the inside and outside of the machine, and caused clogging and malfunctions in various parts.

In view of these circumstances, the present invention aims to provide a peeling device for a green onion peeler that is easy to handle and practical, eliminating the above-mentioned drawbacks.

That is, at least on both sides in the direction of the stem of the white root to be supplied, a stripping device is provided that is equipped with a plurality of injection nozzles that eject toward the root, and the end of the stem is provided on the lower side in the spraying direction of the stripping device. At a position facing the part, there is a removal device consisting of a plurality of blades with uneven cutting edges on a pair of rotating shafts that can rotate inwardly and are planted at roughly radial intervals. By providing this, the aging epidermis of green onions can be exfoliated quickly using pressurized fluid without damaging the white roots, and the exfoliated epidermis, no matter what condition it is in, can be attached to the next incisor. Using a removal device equipped with a blade, it is possible to remove the epidermis that stubbornly covers and adheres to the white roots by applying an appropriate peeling action and removing the epidermis that stubbornly covers and adheres to the white roots due to aging. By making the action of the removal device more flexible and reliable, the fluid injection pressure does not become too large, the green onions are not damaged, and the device can be made smaller. This is an attempt to create an easy-to-use green onion peeler.

Embodiments of the present invention shown in the drawings will be described in detail. 1 is a green onion peeling machine equipped with the device of the present invention; 2;
Reference numeral 2' denotes a pair of conveyor belts that pinch and transport the stalks of green onions from the supply section 1a to the discharge section 1b, and are driven by a motor 3 via a transmission shaft 4. Reference numeral 5 denotes a peeling device of a peeling device installed on both sides of the transfer path by the conveyance belt 2, and this structure is connected to a pump 6 driven by a motor 3 via a conduit 7. The nozzles 8, 8' are provided with a plurality of nozzles 9, 9... in the upper and lower, left and right rows, and the nozzles 9, 9... are directed toward the inner center of the exfoliating device and downward. By providing the directional arrangement, when the water in the water tank 10 sent by the pump 6 is injected as pressurized fluid, the green onions supplied to the central part of the peeling device are immediately removed from the white root part. The epidermis is simultaneously and evenly avulsed from the upper part of the circumference toward the root part of the lower part. Reference numeral 11 denotes a removing device having an axis located in the transfer direction below the scraping device 5 and comprising a pair of scraping wheels 5', 5', etc., which rotate inwardly relative to each other.
As shown in FIGS. 2, 5, and 8, this removing device 11 has a drum 14 mounted on a rotating shaft 13 that is pivotally supported by bearings 12, 12', and a blade having uneven cutting teeth 15 formed on the leading edge. A plurality of plates 16 are installed at the base of the drum 14 at coarse intervals in the radial direction. In the embodiment, the blades 16, 16 are rotated inwardly in response to pressurized fluid applied from above, with the rotation loci of the scraping wheels 5', 5' being lapped. Gears 13', 13', which are provided at appropriate positions on the rotating shafts 13, 13 and mesh with each other, are connected to opposing blades 16,
16 from interfering with each other, and even when pressurized fluid is sometimes injected only to one scraping ring 5', the other scraping ring 5' can also be smoothly rotated to provide a good removal effect. It has the function of making it perform. Further, as shown in FIG. 7 as another embodiment, the scraping ring 5' has its base screwed onto the flattened surface of a hexagonal columnar drum 14 provided on the shaft 13, and has cutting teeth 15 at its leading edge. The scraping wheels 5', 5' may be configured to be recurveable, and the blades 16, 16 may be opposed to each other without being in conflict with each other, and may be provided at a distance to the extent that they do not touch each other. . 17 is the scraping device 5
and the removing device 11, and has a notch 17' extending at least in the upper part of the removing device 11 along a conveyance path narrower than between the rotating shafts 13, 13. , so that the fluid jetted from the nozzle 9 properly hits the blades 16, 16 of both scraping wheels 5', 5', so that both scraping wheels 5', 5' reliably rotate inward to each other. In addition to encouraging
Water, skin waste, mud, etc. scattered within the scraping device 5 are discharged and guided downward from the notch 17'. Reference numeral 18 denotes a tank which is removably installed below the removal device 11 to receive and store water, skin, debris, etc. falling from above, and a water tank for the pump 6 partitioned off by a leakage net 19 is formed inside the tank. has been done. 2
Reference numeral 0 designates a cutter for cutting the root hairs of green onions, which is transmitted and rotated in an appropriate configuration by a rotating shaft 13, and the green onions placed on the deck 21 with their roots aligned are transferred to the conveyor belt 2,
This is for cutting off the root hairs at the initial stage when they are being held and transferred at 2'. Incidentally, in the case where the rotating shaft 13 is rotated by the jetting fluid, it is reasonable to obtain the power for this rotation. 22
is an auxiliary clamping rotor having elasticity that restricts the wobbling of the root at that time, and the conveyor belt 2,
The power is transmitted from 2'. 23 is a housing that receives and stores root hairs that are cut and fallen.

Although the above embodiment shows an example in which the rotation of the scraping wheels 5', 5' is carried out by actively utilizing the force of water jetted from the nozzle 9, the rotation of the scraping wheels 5', 5' is not limited to this. The wheels 5', 5' may be driven by the motor 3 forcibly rotating the rotating shaft 13. Further, although the supply and conveyance of the green onions by the belt 2 may be continuous, it is better if it is carried out intermittently.Furthermore, for example, it is possible to detect when the green onions have been fed to the center of the peeling device. If a sensor is installed and the conveyance is stopped for a certain period of time based on a signal from the sensor, the green onion can temporarily receive sufficient fluid sprayed from all around the green onion, resulting in an extremely effective skin exfoliation. This is preferable because it increases the

Next, the operation of the present invention configured as described above will be explained. The green onion A whose root portions are aligned on the deck 21 is held at the starting end of the conveying belt 2, and the cutter 20 cuts off the root portion of the green onion A, and the green onion A is transferred to the peeling device 5. In the scraping device 5, each nozzle 9, 9
...They are oriented toward the center of each other and downward, so the fluid jetted from the nozzles 9, 9... travels all around the green onion A located in the center from the leaf to the root. Since it is injected toward the target, the skin around the entire circumference is abraded almost simultaneously and uniformly, as shown in FIG. Then, when the tip of the skin B that has been peeled off and hangs downward reaches the inward rotation locus of the scraping wheel 5' (as shown in FIG. 8), the cutting teeth 15 of the blade 16 are first , 9. In the state shown in Figure 9, the skin B is touched and engaged, and at that moment it is peeled off in a B'' shape and the engagement is released. Then, the blade 1 that can be rotated from the other side
6 touches the epidermis B'', bends the epidermis, and peels it off in a B shape, completely separates it from the root, and throws it into the tank 18 below and removes it. Even if there is some skin that is not removed, the blade 16 that is rotated next will engage with it and will surely remove it.

In the above action, the blade 16 engages with the epidermis B, and at the moment of contact, the blade 16 releases its engagement with the epidermis B, and the tips of its teeth create a cut in the epidermis B, making it relatively Since the skin B is peeled off in the direction of rotation while having a slight slip, the green onion itself is not continuously subjected to a strong pulling force in the direction of the stem body, so the green onion falls off from the gripping and conveying portion of the belt 2 and falls downward. The above-mentioned series of operations can be carried out satisfactorily without problems such as poor peeling in the peeling device 5 and clogging in the removing device 11, which would otherwise occur due to falling.

Next, the water jetted from the nozzle 9 performs the above-mentioned peeling action, and the jet stream is directed toward the two rotating shafts 13, 13.
The scraping wheels 5',
5' are rotated inwardly relative to each other. Therefore, in this embodiment, since no special transmission device is required for this purpose, it has the additional advantage that it can be manufactured extremely compactly with a simple structure. Furthermore, even if the jetted fluid collides with the blades 16, since the blades 16 are plate-shaped and provided at coarse intervals, as the blades 16 rotate,
Since the fluid passes between the scraping wheels 5' and 5' while being guided by this, the jetted fluid that hits the removal device 11 does not scatter significantly inside or outside the machine and cause any inconvenience such as staining or clogging various parts. , the drainage of skin debris and fluid is extremely smooth.

The green onions whose skins have been peeled off as described above are conveyed in an orderly manner and sent out of the machine from the discharge section 1b, where a series of operations are completed.

In short, the green onion peeling device according to the present invention provides at least both sides in the stem direction of the white root portion to be supplied.
A peeling device is provided with a plurality of injection nozzles that eject toward the root side, and a pair of rotors that can rotate inward are provided at a position facing the end of the stem on the downstream side in the injection direction of the peeling device. By providing a removal device consisting of a plurality of blades with uneven cutting edges on the shaft, installed at coarse intervals in the radial direction,
When the epidermis is scraped off with the scraping device and placed in front of the removal device, the blades of the scraping wheel with uneven incision teeth engage the epidermis in multiple stages, further peeling off the skin and removing the stem. Since it is separated from the stem flesh and removed, the epidermis and stems, which become stubbornly attached due to aging, can be reliably peeled off and removed from the stem flesh. Therefore, no matter what form the green onions are in, it is possible to perform a smooth and complete peeling operation without pulling out the green onions from the clamping portion. Even if the pressurized fluid injected at this time collides with the removal device, it is smoothly guided downward by the rotation of the scraping wheel in which blades are installed at coarse intervals. It was possible to prevent skin debris and mud that were peeled off along with the pressurized fluid from scattering, and to eliminate the resulting deterioration in scraping performance and the occurrence of problems. In addition, the peeling device only needs to peel the skin of the green onion to the extent that it touches the tip of the blade of the rotating scraping wheel. Since the process is performed reliably, the pressure of the fluid jetted from the peeling device can be relatively low, making it possible to use pressurized fluid to peel the green onions without damaging their white roots. In addition to this, it is possible to use a pump that can be used with a general household power source as the pressurizing device, which greatly improves the ease of handling the device. Furthermore, the peeling device and the removal device can be placed as close as possible to each other in the entire device, and there is little splashing of fluid, making it possible to provide a compact green onion peeling device that is highly efficient and easy to handle. It has many great effects.
