Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a root vegetable peeling machine that generally peels and cleans elongated, flexible root vegetables of varying thickness and irregular shape.

[Conventional technology]

Conventionally, there is a washing machine that uses a rotating brush to wash away mud and foreign substances adhering to the surface of root vegetables, such as burdock, carrots, and radish, by pouring water on them, but it does not have the function of peeling the skins. You can also add long, slender root vegetables of 5 to 10 cm.
There are peeling machines that remove the skin by cutting it into lengths and rotating it in a rotating drum while mixing an abrasive material such as plastic, but they end up cutting too much or leaving parts that cannot be removed. Currently, most of the skins are removed manually using knives.

[Problem to be solved by the invention]

As mentioned above, there are currently no machines or devices suitable for peeling root vegetables that are long, flexible, and easily broken, so if the peeling work is done manually for commercial purposes, in the case of burdock, The limit is 50 to 70 kg per person per day. Average diameter of burdock now
If it is 10 mm, the circumference is 31 mm, and you can peel 2 mm wide with one reciprocation of the knife, so you need to move your hand 15 times.
If the average length of burdock is 50 cm, peeling one burdock would require moving the hand 15 meters, which would be 500 meters if 500 burdock were processed in a day, and the work would not last long because the muscles of the wrist would be overworked. This has resulted in problems such as unstable production plans and no hope of rationalizing processing fees.

The present invention has been made in view of such conventional problems, and aims to solve the above problems by creating a machine that combines a belt conveyor, a brush wheel, a pressing roller, etc.

[Means to solve the problem]

The present invention provides a belt conveyor having a rough belt surface, an upper brush wheel disposed opposite to a conveying surface of the belt conveyor, and a brush wheel disposed opposite to the conveying surface of the belt conveyor, and a a presser roller disposed in a line with the upper brush wheel; a presser roller positioned on the same side as the upper brush wheel across a virtual extension surface of the conveyance surface; and a presser roller disposed on the opposite side of the upper brush wheel. The present invention is a root vegetable peeling machine equipped with a roller and a lower brush wheel facing each other.

Furthermore, providing a water injection nozzle that sprays cleaning water toward the upper brush wheel is effective in preventing clogging of the brush wheel.

It is preferable that the press rollers disposed at least on either side of the front or rear of the upper brush wheel be pivotally attached to the end of the swing arm so as to be able to move forward and backward and rotate freely with respect to the conveyor belt conveyance surface so as to follow the outer shape of the root vegetables.

In addition, since the diameter of the root vegetables varies, the holding roller facing the lower brush wheel can move forward and backward from its fixed position in the direction of the lower brush wheel.
Preferably, the configuration is configured.

Furthermore, in order to synchronize and maintain the rotating shafts of the upper and lower brush wheels, the rotating shaft of the presser roller opposing the lower brush wheel, and the drive shaft of the conveyor belt at predetermined speeds, a timing belt is attached to each of these rotating shafts. It is good to have one.

[Effect]

Since this invention is configured as described above, the root vegetables placed on the conveyor belt are fed at the speed of the belt, and are subjected to a brushing action by the brush wheel, so that irregularly shaped parts can be evenly peeled. be done. The root vegetables are moved by the belt conveyor while being constrained to some extent by the roughened belt by the pressing rollers. At this time, peeling is performed by the upper brush wheel only on one side of the root vegetable surface, which corresponds to 1/2 of the surface of the root vegetable. Next, the peeled part of the one side surface separated from the upper brush wheel is sandwiched between the lower brush wheel and the pressing roller opposing this, and the other side surface of the root vegetable is similar to the one side surface. The skin is peeled off. In other words, by simply placing root vegetables on a conveyor, irregularly shaped areas are automatically and evenly peeled, and the thickness of the peeled skin is evened out, resulting in a beautiful finish and improved yield. This means that manual peeling is completely unnecessary, and the amount of processing per hour can be dramatically increased. Further, the thickness of the peeled skin can be adjusted by adjusting the properties of the brush wheel and increasing or decreasing the number of rotations.

When water is poured from the water nozzle toward the upper brush wheel, the brush wheel is prevented from being clogged with peeled skin, and the root vegetables and the belt surface are cleaned.

Since the pressing roller on the belt conveyance surface is movable toward the conveyance surface, it can press down the root vegetables at all times while moving in response to changes in the thickness of the root vegetables.

The holding roller facing the lower brush wheel has a fixed position that can be changed depending on the size and type of root vegetables, so that it can handle various types of root vegetables.

Since each rotary drive part is rotated synchronously by a timing belt, a series of peeling operations can be carried out smoothly.

〔Example〕

The present invention will be explained below based on the drawings. Fig. 1 is a side view showing one embodiment of the present invention;
The figure is a view taken in the direction of arrow A in FIG. 1, and FIG. 3 shows a brush wheel used in this embodiment.

First, the configuration will be explained.

In FIGS. 1 and 2, 2 is a peeler, 1 is an upper frame, and 3 is a lower frame. Reference numeral 4 denotes a belt conveyor attached to the upper frame 2, and the surface of the belt 5 of this conveyor is roughened by applying abrasive grains or the like to increase frictional force. Reference numeral 6 denotes a first presser roller, which is pivotally attached to one end of the swing arm 7 so as to be able to move up and down and rotate freely, and the other end of the swing arm 7 is pivotably attached to a bracket 8 fixed to the frame 4a of the belt conveyor 4. It is worn. Reference numeral 9 denotes an upper brush wheel, which will be described later, and its peripheral end is attached to a rotating shaft 9a provided on the upper frame 2 to such an extent that it contacts the surface of the belt 5 during rotation. 10 is the second presser roll,
It is attached to one end of the swing arm 11 so that it can move vertically and rotate freely, and the other end of the swing arm is rotatably attached to a bracket and the upper frame 2 (not shown). Further, the first press roller and the second press roller are arranged so as to face each other, and on both sides immediately adjacent to the upper brush wheel 9.
They are arranged in a line in the longitudinal direction of the belt conveyor 4.

Further, a third presser roller 12 is disposed on the upper side across the virtual extension surface of the upper surface of the belt 5, and a lower brush wheel 13 similar to the upper brush wheel 9 is disposed on the lower side so as to be able to roll into contact with the presser roller on the upper frame 2.
It is attached to a rotating shaft 13a provided in the. Third
The pressing roller 12 is the slider 1 of the slide device 14.
5, and the slider 15 is attached to the lower end of a threaded lifting rod 16. The lifting rod 16 is a nut member 1 provided on the upper frame 2.
7, so that by rotating the handle 18 left and right, the third pressing roller 12, which is pivoted to the slider 15, can be moved up and down depending on the diameter of the root vegetable. 19 is a pulley attached to the rotating shaft of the conveyor belt 5.

Reference numeral 20 denotes a timing belt with tooth profiles on both sides, and the intermediate pulley 2 is driven by the power of a motor 21.
2, it rotates in the direction of arrow B, and the tension pulleys 23 and 24, the third presser roller pulley 12a (here, the back side of the timing belt is in rolling contact), and the lower brush wheel pulley 13b. , belt conveyor starting shaft pulley 19, upper brush wheel pulley 9a, intermediate shaft pulley 2
2a to rotate these pulleys and the like. In this example, a double-sided timing belt is used, so each pulley mentioned above is equipped with one for the timing belt.
The present invention is not particularly limited to double-sided timing belts, but includes single-sided timing belts, flat belts,
It goes without saying that a V-belt or chain, and corresponding pulleys, chain wheels, etc. may also be used. 25 is a tension adjustment device for applying appropriate tension to the timing belt 20. A water injection nozzle 24 is provided above the first pressing roller 6 and sprays water toward the brush wheel 9.

FIG. 3 shows the brush wheels 9, 13 in detail. This has a large number of polishing cloths 27 fixed around a rotor 26. Polishing cloth 27
This is made by applying abrasive grains to the surface of a base cloth to make it look like sandpaper, and a large number of this is cut into thin strips and fixed around the rotor 26. As the brush wheels 9 and 13 rotate, the polishing cloth 27 peels off the skin of the root vegetables.

Next, we will discuss the effect.

At the start of work, the motor 21 is first driven to transmit rotational force to the timing belt 20, and each pulley is rotated as described above, whereby the conveyor belt 5, upper brush wheel 9, third presser roller 12, and lower part are rotated. The brush wheels 13 are rotated synchronously at a predetermined speed.

Now, when root vegetables are placed on the conveyor belt 5 with their longitudinal direction as the feeding direction, they move and come into contact with the first pressing roller 6. At this time, the root vegetable does not move backward due to the frictional force with the conveyor belt 5 formed on the rough surface, but pushes up the first pressing roller 6 and moves forward together with the belt 5. At this time, the root vegetables are
The belt 5 is subjected to a certain amount of restraining force due to the frictional force with the belt and the own weight of the first pressing roller 6.
The polishing cloth constituting the upper brush wheel 9 applies a brushing action similar to a "dust-removal duster," so that irregularly shaped areas are evenly peeled off. At this time, due to the above-mentioned binding force, the root vegetables do not travel along the surface of the belt 5 and get caught up in the brush wheel 9, but move together with the belt 5 at the feeding speed. Further, at this time, peeling is performed by the upper brush wheel 9 only on the upper surface corresponding to 1/2 of the surface of the root vegetable. Next, the part of the upper surface that is peeled off and separated from the upper brush wheel 9 moves forward while being sandwiched between the second press roller 10 and the belt 5 surface, and is moved between the third press roller 12 and the lower brush wheel 13. While being pinched, the root vegetable is peeled on its lower surface as well as its upper surface. At this time, the root vegetables are restrained by the weight of the second pressing roller 10 and the frictional force of the belt 5 surface, so that they are not pulled into the lower brush wheel 13 faster than the feeding speed of the belt 5. The third pressing roller 12 is driven by a timing belt 20 so that its circumferential speed is approximately the same as that of the conveyor belt 5.

Further, the lifting rod 16 is raised and lowered as described above depending on the thickness of the root vegetables to be processed (for example, radish and burdock).

In this way, the root vegetables pass through the brush wheels 9, 13, become peeled products, and are put into a water tank or washing machine (not shown). Further, the injection nozzle 24 prevents the polishing cloth of the brush wheel from clogging, and the material can be cleaned in the same way.

Next, as an example, the brush wheel shown in Fig. 3 has abrasive cloth made of #80 abrasive grains, cut to a width of 2 mm, and lined up to form a wheel width of 50 mm, with a rotating diameter of 235 mm. When the skin of burdock was peeled by rotating at 500 to 700 rpm and the feed speed of the conveyor and the third pressing roller was 30 m/min, about 100 kg could be processed per hour.
This corresponds to 1.5 to 2 working days when processing is performed manually. The product has a glossy surface because only the leather part is evenly shaved, resulting in a process with excellent commercial value. When I peeled various root vegetables, carrots, yams, and butterburs in the same way, the results were similar to those of burdock.

In the above embodiment, the root vegetables were fed in a horizontal direction from right to left in FIG. It may also be the direction of movement. In these cases, the pressing rollers 6, 10
The conveyor belt 5 may be biased by a spring.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to efficiently peel a large amount of root vegetables that are elongated, soft, irregularly shaped such as conical shapes, and easily break, thereby increasing the value of the raw product and improving the yield. This has many benefits, such as greatly improving labor management and management efficiency as the work is light and labor-intensive.
