Description

[Detailed description of the invention] (Field of industrial application) The present invention is a polyurethane foam used for cleaning and polishing potatoes, root vegetables, and fruits (hereinafter simply referred to as potatoes), or a polyurethane foam with larger pores of 6 to 53. The present invention relates to an improvement in a sponge roll for cleaning, in which a rotating shaft body is thickly covered with a cylindrical sponge material such as a three-dimensional mesh filter having a cell range of approximately 1/2 cells/mm.

(Prior Art) Conventionally, sponge rolls for washing potatoes have simply been made by covering a rotating shaft with a thick cylindrical sponge body. A plurality of these are arranged in rows and rotated in one direction, and the potatoes are fed onto the rows and rubbed between them with the brush and sponge above to be washed and polished. Moreover, in addition to installing multiple sponge rolls in this manner, it is also possible to use only one sponge roll as a part of the cleaning device.

(Problems to be Solved by the Invention) A conventional single-piece cylindrical sponge roll is difficult to deform according to the shape of the potatoes, and therefore tends to cause uneven cleaning. In order to reduce this, the upper brush and sponge are used to press firmly and rotate the potatoes so that the surface of the potatoes is brought into close contact with the sponge roll. However, even when pressed with a strong pressing force, it does not adhere sufficiently to potatoes with large irregularities, and there is a drawback that uneven cleaning is likely to occur. Another drawback was that the frictional force became too strong due to the strong pressing force, and a large amount of horsepower was required to rotate the sponge roll.

The problem of this invention is to solve the drawbacks of conventional sponge rolls, to achieve high cleaning and polishing ability, and to achieve uniform and even cleaning and polishing, while also being able to rotate with less horsepower, making it practical for cleaning. The idea is to offer sponge rolls.

(Means for Solving the Problems) The gist of the present invention that solves the problems is as follows: 1. In a cleaning sponge roll in which a thick cylindrical sponge body is covered with a rotating shaft body, the sponge body is moved in the axial direction as required. Sponge roll for cleaning potatoes, root vegetables, and fruits 2, characterized in that it is divided into a plurality of sections at intervals and that a plurality of wide deep grooves are provided in the circumferential direction on the sponge body of each section. The potato/root vegetable according to claim 1, wherein the wide deep grooves are in the same angular phase and communicate for a long time in the axial direction.
Sponge Roll for Washing Fruits 3 The sponge roll for washing potatoes, root vegetables, and fruits according to claim 1, wherein the phase or number of wide deep grooves in each section is different depending on the section.

(Function) In this invention, since the sponge body is divided into a plurality of sections in the axial direction, it is easier to deform along the external shape of the potato compared to a one-piece sponge body. Moreover, since it is partitioned by a plurality of wide and deep grooves in the circumferential direction, it adheres more closely to the outer shape of the potatoes, allowing for high cleaning power and uniform cleaning. In addition, since it is not necessary to force the pressure contact by applying a strong pressing force, the horsepower required to drive the sponge roll can be small. Furthermore, the cleaning and polishing ability can be enhanced by impact and etching due to the wide deep grooves provided in the circumferential direction.

(Example) Examples will be described below based on the drawings.

The embodiment shown in Figs. 1 to 4 has wide deep grooves 2 in each section.
The grooves were made to have the same angular phase so that the grooves were long and communicated in the axial direction, and the sponge body 1 was made of a filter material having a fairly coarse three-dimensional mesh structure. A plurality of sponge rolls 3 are arranged horizontally in a row, and a plurality of plate-shaped sponge plates 4 made of the same material and divided into a plurality of sections are pivotally supported above the sponge rolls 3.

In the figure, 5 is the rotating shaft of the sponge roll 3, 6 is the central rotating shaft of the rotating shaft, 7 is the pivot shaft of the sponge plate 4, 8 is the casing of the cleaning device, and 9 is the gear attached to the central rotating shaft 6. , 10 is a chain that drives the same gear, and 11 is a potato.

In this embodiment, a potato 11 is sent onto a sponge roll 3, and while being conveyed by the rotation of the sponge roll 3, friction is caused between a sponge body 4 and the sponge roll 3, and the sponge body 4 is pressed. The sponge roll 3 is deformed into the outer shape of a potato 11 by pressure and is evenly and powerfully cleaned and polished.

Here, as shown in FIG. 6, the upper sponge plate 4
Alternatively, the plate brush 12 can also be used.

Further, the wide deep groove 2 of the sponge roll 3 is the fifth groove.
As shown in the figure, there are cases where they are out of phase and do not communicate.

FIG. 7 shows an example of a method for manufacturing a cylindrical sponge body 1 with deep grooves. In the figure, 20 is a cutting line.

(Effects of the invention) As described above, according to the invention, by dividing the sponge body into a plurality of sections at required intervals in the axial direction and providing wide deep grooves in the circumferential direction, a large pressing force can be achieved. The sponge roll can be deformed along the outer shape of the potatoes without the need for it, and can have uniform and high cleaning and polishing ability. Moreover, the effect is further enhanced by the friction caused by the impact caused by the corners of the deep grooves. In addition, since a large pressing force does not cause strong frictional resistance, the horsepower required to rotate the sponge roll can be reduced.
