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, irregularly shaped root vegetables).

[Conventional technology]

Conventionally, there is a washing machine that uses a rotating brush to rinse half a carrot, radish, etc. with water to wash away dirt and foreign matter adhering to the surface of root vegetables, but it does not have the function of peeling the skin. There is also a peeling machine that cuts long and thin root vegetables into lengths of 5 to 100 mm and rotates them in a rotating drum while mixing an abrasive material such as plastic to peel off the skin. As a result, most of the skin is now removed manually using a knife.

[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 half the cases, The limit is 50 to 70 kg per person per day. If the diameter of the current half is 10 on average, the circumference is 31':
, you can peel a width of 2m + with one round trip of the knife, so 15
It is necessary to move the hands around, so let's assume that the average length is 50c.
If it is m, then to peel half of one strand, you will have to move your hand 15 meters, which is 500 meters if you process 500 strands in a day.
Problems arise in that the work does not last long because the muscles of the wrist are overworked, the production plan becomes unstable, and it is impossible to rationalize the processing fee.

The present invention was 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 for Solving the Problems) 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 an upper brush wheel disposed on the conveying surface. A press roller disposed in a line with the upper brush wheel at least in front or rear of the wheel; a press roller positioned on the same side as the upper brush wheel across a virtual extension surface of the conveying surface; and a lower brush wheel disposed on the opposite side of the presser roller and facing the presser roller.

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, the presser roller facing the lower brush wheel is
Since root vegetables have different diameters, it is preferable to configure the fixing position so that it can move forward and backward in the direction of the lower brush wheel.

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 brushed by the brush wheel, so that irregularly shaped areas 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 surface corresponding to 1/2 of the root vegetable surface. Then,
The peeled part of the - side surface that is separated from the upper brush wheel is sandwiched between the lower brush wheel and the pressing roller opposing it, and the other side surface of the root vegetable is peeled in the same way as the - side surface. stripped. 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 be used with various types of root vegetables.

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

The present invention will be explained below based on the drawings. FIG. 1 is a side view showing one embodiment of the present invention, and FIG. 2 is A of FIG. 1.
The arrow view, FIG. 3, shows the 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. 6 is the first pressing roller and the swing arm 7
The swing arm 7 is pivotably attached to one end of the swing arm 7 so as to be vertically movable and rotatable, 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.

Reference numeral 9 denotes an upper brush wheel to 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. Reference numeral 10 denotes a second presser roll, which is attached to one end of the swing arm 11 so as to be able to move up and down once, 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 to form a line in the longitudinal direction of the belt conveyor 4 on both sides immediately adjacent to the upper brush wheel 9.

Further, a third presser roller 12 is provided on the upper side sandwiching the virtual extension surface of the upper surface of the belt 5, and a lower brush wheel 13 similar to the above-mentioned upper brush wheel 9 is provided on the lower side of the upper frame 2 so as to be able to roll into contact with the presser roller. It is attached to a rotating shaft 13a provided. The third pressing roller 2 is the slide device 1
4, and the slider 15 is attached to the lower end of a lifting ring 16 having a thread. The lifting ring 16 is screwed into a nut member 17 provided on the upper frame 2, so by rotating the handle 18 left and right, the third presser roller 2, which is pivoted on the slider 15, can be moved according to the size of the root vegetable diameter. It is able to move up and down. 19
is a booth attached to the rotating shaft of the conveyor belt 5.

20 is a tie straw belt with tooth profiles on both sides,
Due to the power of the motor 21, rotational force is applied via the intermediate pulley 22 to rotate in the direction of arrow B, and the tension pulleys 23, 24 and the third presser roller pulley 12a (here, the back side of the timing belt is in rolling contact) , lower brush wheel pulley 13 sister, belt conveyor starting shaft pulley 1
9. Upper brush wheel pulley 9a, intermediate shaft pulley 2
2a, respectively, to rotate these boots and the like. In this embodiment, a double-sided timing belt is used, so each of the pulleys mentioned above is for a timing belt. However, the present invention is not particularly limited to double-sided timing belts, and can be used for single-sided timing belts or flat belts. .

■It goes without saying that belts, chains, etc., and corresponding pulleys, chain wheels, etc. may be used. 25 is a tension adjustment device for applying appropriate tension to the timing belt 20. A water nozzle 24 is provided above the first presser roller 6 and sprays water toward the brush wheel 9.

FIG. 3 shows the brush wheels 9, 13 in detail. This means that there are many polishing cloths 27 around the rotor 26.
is fixed. The polishing cloth 27 is a base cloth whose surface is coated with abrasive grains to make it look like sandpaper, and the rotor 26
It is planted and fixed around the area. This brush wheel 9,1
3, the polishing cloth 27 peels off the skin of the root vegetable.

Next, we will discuss the effect.

When starting work, first, the motor 21 is driven to transmit rotational force to the timing belt 20, and each boot is rotated as described above, thereby removing the conveyor belt 5, upper brush wheel 9, third press roller 12, The lower 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 due to 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 affected by the frictional force with the belt and the first pressing roller 6.
It is fed at the speed of the belt 5 while receiving a certain amount of binding force due to its own weight, and is subjected to a brushing action such as "dust removal dusting" by the abrasive cloth forming the upper brush wheel 9. Even irregularly shaped areas are peeled off evenly. At this time, due to the above-mentioned binding force, the root vegetables do not cross the surface of the belt 5 and get caught up in the brush wheel 9, but move together with the belt 5 at the same feeding speed. Also,
At this time, peeling is performed by the upper brush wheel 9/) only on the upper surface corresponding to 1/2 of the root vegetable surface. 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. On this occasion,
The root vegetables are restrained by the weight of the second pressing roller IO and the frictional force of the belt 5 surface, and are prevented from being drawn into the lower brush wheel 13 faster than the feeding speed of the belt 5. The timing belt 2 is adjusted so that the circumferential speed of
Driven by 0.

Further, the elevating frame 16 is raised and lowered as described above depending on the thickness of the root vegetable to be processed (for example, a radish and a half).

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 water injection nozzle 24 prevents the polishing cloth of the brush wheel from clogging, and the material can also 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 InTn, with a rotating diameter of 235 m. Rotate at 500 to 700 rpm, and increase the feed speed of the conveyor and third press roller to 30 m/min.
When half of the skin was peeled as a minimum, about 100 kg could be processed per hour. This corresponds to 1.5 to 2 days of operation in the case of manual processing. The product has a glossy surface with only the skin part being evenly shaved.
Processing with excellent product value was achieved. In the same way, I peeled various root vegetables, carrots, yams, and butterbur, and the results were similar to those of the cows.

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 pressure roller 6.10 may be biased against the conveyor belt 5 by means of a spring.

[Effects 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. With this increase, yields can be improved, and labor management and management efficiency can be greatly improved because the work is light labor, and many other benefits can be obtained.
