Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for polishing the surface of root vegetables such as potatoes and sweet potatoes after washing with water.

(Prior Art) Conventionally, polishing of root vegetables such as potatoes and sweet potatoes (hereinafter simply referred to as potatoes) after washing with water is generally performed manually using cloth. A polishing device that mechanically performs this polishing work consists of a plurality of sponge rolls, each of which has a uniform wall thickness over the entire surface and is integrally disposed around the sponge, to form a conveyance path, and a plate-shaped roller fixed above the sponge rolls. A sponge is provided, and the potatoes are rubbed between the sponge roll and the plate-shaped sponge while being fed through the sponge roll for polishing.

(Problems to be Solved by the Invention) Manual polishing work has the drawbacks of being time-consuming and high-cost. In addition, in the conventional polishing mechanism using sponge rolls and plate-shaped sponges,
Since the sponge roll is a one-piece product, it cannot be sufficiently deformed to follow the shape of the potato, making it impossible to thoroughly polish the entire potato. Furthermore, if the potato was strongly pressed with a sponge to solve this problem, the sponge roll would feed the potato too quickly, causing the potato to be discharged before it could be polished sufficiently.

An object of the present invention is to solve these conventional drawbacks and problems and to provide an apparatus that can thoroughly and uniformly polish potatoes.

(Means for Solving the Problems) The gist of the present invention that solves the problems is as follows: 1. A plurality of rotary tubes are connected in series in a conveyance path for root vegetables such as potatoes, and the outer periphery of each rotary tube is At the same time, a plurality of thick sponges are installed around the outer circumferential surface of each section so as to be fixed at one end, separated by a required distance, and the fixed part of the sponge body is made thin and the entire outer circumference of the rotating cylinder is A polishing device for root vegetables 2, which is covered with the same sponge body and further provided with a presser sponge above the rotary cylinder to which these sponge bodies are attached. 3. A polishing device for root vegetables according to claim 1, wherein one end of the sponge body is fixed to the shaft and the sponge body is disposed around a rotating tube. The root vegetable polishing device 4 according to claim 1 or 2, wherein a sponge is provided. The root vegetable polishing device 5 according to claim 3, wherein the presser sponge is divided into a plurality of pieces with a required width. The rotary tubes are arranged in series, the outer periphery of each rotary tube is divided into a plurality of sections in the direction of the rotation axis, and a thick annular sponge body with a plurality of large recesses is provided on the outer circumferential surface of each section is independently wrapped. A polishing device for root vegetables 6 further comprising a presser sponge provided above a rotary cylinder wrapped with these sponge bodies.A claim wherein the presser sponge is provided with its upper end fixed and its lower part swingable from side to side. Root vegetables polishing device 7 according to claim 5. The root vegetables polishing device according to claim 6, wherein the presser sponge is divided into a plurality of pieces of required width.

(Function) In the present invention, the sponge body wrapped around each rotary tube forming the conveyance path is divided into a plurality of sections in the direction of the rotation axis and attached independently. Therefore, when a potato is pressed against the sponge body, the sponge body compresses and deforms along the unevenness and curves of the potato according to its section. This deformation is much easier to compress and deform than a one-piece long sponge because the width is short and it is not affected by tension from other parts of the sponge, and it takes the shape of a potato. along the entire surface of the potato. In particular, if the presser sponge is divided into a plurality of pieces along the longitudinal direction, the adhesion to the potato can be further improved. Therefore, as the rotary tube rotates, the sponge body comes into close contact with the potato and polishes the potato uniformly and over the entire surface. This can be done more effectively by further dividing the divided sponge body into a plurality of parts and disposing them around the circumference of the rotary cylinder. If there is a large difference in the thickness of the sponge body at the seam of the sponge body, or if a large recess is formed in the annular sponge body, the potatoes will fall into the seam or the concave part of the sponge body and stagnate for a short time, causing damage to the rotating cylinder. Even though the rotational speed remains the same, the feeding speed of the potato is slowed down to ensure a long polishing time. In addition, this combined with the fact that the potato's posture is moved makes it possible to polish the potato more thoroughly and thoroughly.

Furthermore, by fixing the upper end of the presser brush and making it swingable, the upper presser brush will also adapt to the potatoes, effectively polishing the potatoes, and slowing down the feeding speed of the potatoes.
The polishing force can be increased by increasing the rotational speed of the rotary cylinder.

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

First embodiment (see Figs. 1 to 5) The embodiment shown in Figs. and can be installed independently. Further, the sponge body is removably attached to a plurality of shafts horizontally mounted on a flange plate provided at the end of the rotating cylinder. Further, the upper end of the presser sponge is fixed to a shaft, and the coaxial shaft is hooked to a locking metal fitting on the top plate of the device so that it can swing freely.

In the figure, 1 is a rotating cylinder, 2 is a rotating shaft of the rotating cylinder, 3 is a sponge body, 4 is a presser sponge fixed to a plate sponge folded in half and the supporting shaft is sandwiched between the folds, 5 is a rotating cylinder 1. A flange plate provided at the end, 6 a locking groove provided in the flange plate, 7 a shaft to which the sponge body is fixed, 8 a support shaft attached to the upper end of the presser sponge 4, 9 a casing, and 10 a A top plate, 11 is a spring that elastically supports the top plate 10, 12 is a horizontal brush, 1
3 and 14 are dividing lines dividing the sponge body 3 and the presser sponge 4; 15 is a receiving bracket for the support shaft 8 provided on the back surface of the top plate 10; 16 is a washing brush; 17 is a washing roll brush; It is.

In this embodiment, the shaft 7 attached to one end of the sponge body 3 is connected to the locking groove 6 of the collar plate 5 provided at both ends of the rotary cylinder 1.
It can be easily attached and detached by hanging it horizontally between the two. The presser sponge 4 also has its support shaft 8 connected to the top plate 10.
It can be easily attached by hooking it to the receiving metal fitting 15 on the back side.

In this embodiment, the sponge body 3 and the presser sponge 4
Since both are sectioned and divided into required widths, the sponge in each section can be easily compressed and deformed faithfully along the shape of the potato. Three or four sponge bodies are attached to each section of the rotary cylinder 1 with a 90° phase difference, and the sponge at the shaft 7 portion does not protrude much, and at its free end, the sponge remains thick. , settling occurs on the surface of the sponge at the shaft 7 portion.

FIG. 5 shows the compressive deformation of the sponge body 3 and presser sponge 4 by the potato 18. By having the two sponges in close contact with the potato in this way, the surface of the potato can be thoroughly polished.

Furthermore, in this embodiment, the sponge body 3 and presser sponge 4 are removable and can be easily replaced, making it easy to replace the sponge when worn out.

Second Embodiment (See Fig. 6) In the embodiment shown in Fig. 6, the sponge body 20 attached to the rotary tube 1 is annular and integral, and has four large recesses 21 formed in each section. This is an example. In this embodiment, the sponge body 20 is not divided into a plurality of parts along the outer periphery of the rotary cylinder 1, but is integral. Therefore, the deformation along the shape of the potato is not as good as in the first embodiment. The advantage of this embodiment is that the sponge body is easy to manufacture. The rest is the same as the first embodiment.

(Effects of the Invention) As described above, according to the present invention, potatoes can be thoroughly and thoroughly polished.

In addition, in the case where the sponge body is attached to the shaft horizontally suspended on the flange plate and detachably attached to the rotary cylinder, it is easy to change the sponge body due to wear and tear. In addition, by fixing the presser sponge at its upper end and making it swingable, or by dividing the presser sponge into a plurality of sections in the longitudinal direction, it is possible to reduce the feeding speed of the potatoes and improve the adhesion with the potatoes.
