Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a cleaning device for cleaning long root vegetables such as burdock, radish, and Japanese yam to cleanse their skin and increase their commercial value. be.

(Prior Art) Various devices have been proposed for cleaning long root vegetables such as burdock, radish, and Japanese yam, but no one has yet been proposed that is perfect.

Recently, a device has been proposed according to Japanese Patent Publication No. 60-141267, but since this device uses a brush for feeding, the frictional resistance is small, and the feeding caused by the cleaning brush, which has a faster circumferential speed than the feeding brush, has been proposed. Easily slip on the feed brush part with force,
It is not possible to firmly hold the object to be processed between the forward and rearward adjacent feed brushes. Furthermore, since the circumferential speed of each feed brush is set to be the same, the feed force from the cleaning brush is also applied between the front and rear feed brushes.
If the amount of feed by the previous feed brush is greater than the amount of feed by the later feed brush, foods that are particularly prone to breakage, such as Japanese yam or thin burdock root, may break or get wrapped around the brush, causing work to be interrupted or products to be damaged. There was a problem that the yield was low.

(Purpose of the invention) The present invention solves the above-mentioned problem, namely, to provide an apparatus that can effectively clean the objects to be processed without damaging the objects to be processed, so that they do not break easily or get wrapped around the brush. purpose.

(Means for solving the problem) In order to achieve the above object, the present invention does not use a brush for feeding, but instead uses a roll coated with a cushioning material such as sponge rubber that has high frictional resistance. By increasing the circumferential speed of the feed roll from the inlet side to the outlet side, the slip of the feed roll can be reduced, and the amount of feed by the later feed roll can be made smaller than that of the previous feed roll and the cleaning brush. This solves problems such as breakage of the object to be washed due to bulging and wrapping around the brush caused by the difference in the feed amount between the front and rear feed rolls.

(Example) An example of the present invention will be described below based on the drawings.

In FIG. 1, which shows the long root vegetable washing device in side cross section, it is made up of left and right side plates 1, 2, both end plates 3, 4 at the inlet and outlet, a water receiving plate 5 at the bottom, and a ceiling plate 6 at the top. A shower cleaning chamber 7 is configured. A root vegetable input window 3a is opened in the entrance end plate 3, and a root vegetable input pedestal 8 is horizontally arranged on the outer surface of the end plate 3 below the input window 3a. 4 has a root vegetable extraction window 4a. A root vegetable receiving container 9 is arranged below the root vegetable extraction window 4a.

In order to transfer the workpiece W from the right-hand inlet to the left-hand outlet in FIG. A pair of upper and lower feeding driving and driven rolls A1 to A7 and A1' covered with a high-resistance buffer.
~A7' are rotatably suspended horizontally at intervals shorter than the length of the object W to be processed. One end of the rotating shafts 10 and 11 of these driving and driven feed rolls A1 to A7 and A1' to A7' protrudes from the outer surface of the side plate 1 by a predetermined length, and a number of As shown in Fig. 2, gears 12 and 13 that mesh with each other are keyed, and each drive feed roll rotation shaft 10 is fitted with a chain gear whose number of teeth decreases in sequence from the inlet side to the outlet side. The drive feed rolls A1 to A7 are connected to a motor 16 via an intermediate shaft 15 so that their rotation becomes faster (approximately 1.1 to 1.8 times faster in the embodiment) as they go from the inlet side to the outlet side via the chain mechanism 14. It's on.

B1, B1', B2, B2' and B3, B3' are pairs of cleaning vertical brushes on the left and right, respectively, between feed rolls A1 and A2, between A3 and A4, and between A5,
The rotating shafts 17 and 18 of these vertical cleaning brushes are rotatably supported between upper and lower frames 19 and 20. The lower ends of the rotating shafts 17 and 18 of these vertical cleaning brushes are connected to a drive shaft 23 via bevel gears 21 and 22, as shown in FIG.
4 to the motor 16. And each pair of cleaning vertical brushes B1, B1', B2, B
2', B3, and B3' are rotated in the feeding direction of the workpiece W, and their circumferential speeds are appropriately higher than the circumferential speeds of the respective feed rolls arranged before and after them (in the example, about 2 to 4 times). faster).

C1, C1', C2, C2' and C3, C3' are driving and driven horizontal brushes for cleaning which form an upper and lower pair;
They are arranged between feed rolls A2 and A3, between A4 and A5, and between A6 and A7, respectively, and these driving and driven cleaning horizontal brush rotation shafts 25 and 26 can rotate between left and right side plates 1 and 2. It is suspended horizontally. Further, one end of each of the rotating shafts 25 and 26 of these cleaning horizontal brushes protrudes from the outer surface of the side plate 2 by a predetermined length, and the brushes engage with each other around the protruding shafts as shown in FIG. Matching gears 27 and 28 are keyed together, and a driving horizontal cleaning brush rotating shaft 25 is connected to the motor 16 via a chain mechanism 29.

and each pair of cleaning horizontal brushes C1, C1',
C2, C2' and C3, C3' are rotated in the feeding direction of the workpiece W, and their circumferential speeds are appropriately faster than the circumferential speeds of the respective feed rolls arranged before and after them (2 to 4 in the example). (approximately twice) is set.

In addition, in this embodiment, the cleaning brushes B3, B
3' and C3, C3' are the other cleaning brushes B1, B.
1', B2, B2', C1, C1' and C2, C
A softer (thinner line) brush than 2' is used for final cleaning. On the other hand, shower cleaning room 7
Inside, a shower pipe 30 for spraying water toward each cleaning brush is supported and arranged on the upper surface of the upper frame 19.

The water receiving plate 5 forming the bottom of the shower cleaning chamber is inclined downward from both left and right ends toward the center, and a water collection gutter 31 is formed in the center. The water collection gutter 31 is inclined downward from both its front and rear ends toward the approximate center, and a drainage gutter 32 is formed in the center and extends downwardly to the outside of the shower cleaning chamber 7. It's being served.

The present invention is constructed as described above, and the workpiece W introduced into the shower cleaning chamber through the input window 3a of the inlet end plate 3 is transported by the feed rolls A1 to A7 and A1' to
It is transported from the inlet to the outlet by A7'.

When the object to be processed W is transferred, both sides of the outer circumferential surface of the object to be cleaned W are sequentially exposed to the cleaning brushes B1 and B1'.
C1, C1'B2, B2', C2, C2', B3,
B3', C3, and C3' rub and clean the area while spraying water from the shower pipe.

At this time, it is possible to reduce the slip phenomenon at the front feed roll section that occurs due to the circumferential speed of the cleaning vertical brush and the cleaning horizontal brush being set higher than the peripheral speed of the feed rolls disposed before and after them, respectively. In order to do this, by using a shock absorber with high frictional resistance such as sponge rubber on the feed roll, the workpiece W is firmly held between the front and rear adjacent feed rolls, and the circumferential speed of the previous feed roll is reduced. By appropriately increasing the circumferential speed of the later feed rolls, the amount of feed by the later feed rolls is greater than the amount of feed by the previous feed rolls and the cleaning brush. The cleaning work can be performed satisfactorily without any breakage of the object W to be cleaned due to the bulge caused by the difference in the feed amount or the wrapping around the brush.

In the above embodiment, a pair of vertical and horizontal cleaning brushes is used as the cleaning brush, but FIG. 5 shows an example in which a pair of diagonal cleaning brushes is used.

In FIG. 5, D, D' and E, E' are pairs of cleaning brushes disposed in opposite directions at an angle of approximately 45 degrees with respect to the horizontal plane, and are horizontal cleaning brushes C1, C1' in FIG. Instead of the above cleaning diagonal brush D,
In addition, the cleaning diagonal brushes E and E' are used in place of the vertical cleaning brushes B2 and B2'.

These cleaning diagonal brushes are the driving brushes D and E.
At the lower end of the rotating shaft of the drive brush, as shown in FIG. It has been made possible.

By also employing a cleaning diagonal brush, the entire outer periphery of the object W to be cleaned can come into contact with the cleaning brush evenly, so that the cleaning effect can be further improved.

(Effects of the invention) As described above, the invention uses a shock absorber with high frictional resistance such as sponge rubber as the feed roll, and makes the circumferential speed of the subsequent feed roll appropriately higher than the circumferential speed of the previous feed roll. Therefore, the workpiece is firmly held between the front and rear adjacent feed rolls, and the workpiece is prevented from breaking due to bulging and winding around the brush due to the difference in the feed amount between the front and rear feed rolls. The cleaning work was carried out in a good manner with a high yield and no sticking occurred, and products with high commercial value could be provided.
