Description

[Detailed description of the invention] This invention relates to a cleaner for melons, etc., which removes dirt such as mud adhering to the surface of melons, etc. while moving the melons, etc. along three brush rollers that are close to each other. It is something.

Conventional machines of this type include two brush rollers arranged in parallel above both sides of a lower brush roller, such as the fresh fruit surface treatment machine described in Japanese Utility Model Publication No. 54-27428. One of them is attached to a frame that is rotatable around the rotation axis of the lower brush roller, and this brush roller and the other brush roller (the one with the longest bristles) are thereby connected.
There is one in which the distance between the two can be adjusted depending on the size of the fresh fruit.

However, with this type of conventional type, even if the underframe is rotated to adjust the distance between the brush rollers on both sides, the three brush rollers remain parallel, so for example, fresh fruit is relatively dirty. When there is little need to polish the entire length of the brush roller,
The disadvantage is that it is not possible to improve efficiency by using only a portion of the length of the brush roller for polishing and using the remaining portion to move the fruit at high speed without applying resistance. On the other hand, if the fresh fruit is very dirty and needs to be polished for as long as possible, if the distance between the brush rollers on both sides is too narrow in an attempt to increase the resistance applied to the fresh fruit, the fresh fruit will be brushed. Since the brush rollers do not enter between the rollers, the distance between the brush rollers on both sides should be adjusted as narrow as possible within the range that the fresh fruits can be introduced without any problem, but with such a spacing, it is difficult to apply too much resistance to the fresh fruits. Therefore, the fresh fruit is discharged from between the brush rollers before the time required to sufficiently remove the dirt from the fresh fruit has elapsed, and therefore, the dirt from the fresh fruit cannot be sufficiently removed. It was hot.

This invention eliminates the drawbacks of the above-mentioned conventional ones, and uses the supporting shafts at both ends of the polishing brush roller with the longest bristles, which is located on one side of the three brush rollers.
The distance between this and the feed brush roller located on the other side can be adjusted separately for each end, so that the distance between the polishing brush roller and the feed brush roller is narrower on the inlet side and wider on the outlet side. or
Another object of the present invention is to provide a cleaner for melon, etc., which can have a wide inlet side and a narrow outlet side.

Next, this invention will be specifically explained based on the illustrated embodiment. FIG. 1 is a perspective view of the entire device with the brake plate removed to clarify the arrangement of the rollers.

Reference numeral 1 in the figure is a machine frame, and the machine frame 1 is movable by wheels 1a provided at its lower part.
At the top of the machine frame 1, a receiving brush roller 2 and a feed brush roller 3 disposed in parallel and close to one side above the receiving brush roller 2 are rotatably attached. Both the receiving brush roller 2 and the feeding brush roller 3 have nylon brushes planted around a support shaft, and the receiving brush roller 2 has a cylindrical peripheral surface, while the feeding brush roller 3 has a cylindrical circumference. A spiral protrusion 3a is formed on the circumferential surface. A polishing brush roller 4 is disposed close to and above the other side of the receiving brush roller 2, and support shafts at both ends of the polishing brush roller 4 are attached to be swingable about a fulcrum 5 at the front of the machine frame 1. front lever 6
and a rear lever 8 which is attached to the rear of the machine frame 1 so as to be swingable about a fulcrum 7, respectively. The front lever 6 is constructed by tightening a connecting plate 9 pivotally connected thereto and a bracket 10 provided at the front of the machine frame 1 with a screw 12 inserted through a long hole 11 formed in the connecting plate 9. Thus, it can be fixed at any position within the elongated hole 11. The rear lever 8 is assembled by tightening a connecting plate 12 pivotally connected thereto and a bracket 13 provided at the rear of the machine frame 1 with a screw 15 inserted through a long hole 14 formed in the connecting plate 12. It is adapted to be fixed at any position within the range of the elongated hole 14. The polishing brush roller 4 has a brush made of Yuro installed around the spindle.
The peripheral surface is formed into a cylindrical shape with a larger diameter than the receiving brush roller 2 and the feeding brush roller 3. The receiving brush roller 2 and the feeding brush roller 3 are
The rotational force of the motor 16 is fixed to the machine frame 1.
The protrusion 3a moves the melon, etc. from the front to the rear by being transmitted to the rotating shaft 17 supported by the rotary shaft 17 via the chain 18, and further transmitted from the rotating shaft 17 via the chain 19. It is designed so that it can be rotated in the direction in which it is rotated. Polishing brush roller 4
The rotating force of the motor 16 is transmitted through the chain 20, so that the receiving brush roller 2 and the sending brush roller 3 are rotated in the same direction and at a higher speed than both rollers. Also chain 2
0 engages with a sprocket 21 rotatably attached to the lower end of the front lever 6, and a spring 22 stretched between the lower end of the front lever 6 and the machine frame 1.
Sprocket 21 is connected to chain 2 by the tensile force of
By constantly applying tension to 0, the polishing brush roller 4 is always rotated reliably even if the fixed position of the front lever 6 is arbitrarily adjusted. 23 is a handle attached to the upper end of the front lever 6.

Side walls 24, 24 are provided on the upper part of the machine frame 1 so as to sandwich the three rollers 2, 3, 4 from the left and right sides, and a guide plate 26 is attached to the inside of one of the side walls 24 via a bracket 25. This guide plate 2
6 is disposed almost along the top of the feed brush roller 3, and the inner surface of the guide plate 26 is made of rubber,
Attach cushioning material such as sponge. In this way, three rollers 2, 3, 4 are placed on the bottom of the machine frame 1.
A transport path 27 for melons, etc., is formed, which is closed by the polishing brush roller 4 and the guide plate 26 at its sides.

Furthermore, as shown in FIGS. 2 and 3, a pair of front and rear brake plates 2 are installed in order to change the direction of rotation of melons, etc. from the upper open portion toward the transport direction within the transport path 27.
8,28 are provided. The front ends (inlet side) of the brake plates 28, 28 are pivotally connected to the front and rear support rods 29, 29 extending over the tops of the left and right side walls 24, 24, and the rear ends are connected to the adjacent support rods 29, 29. It is suspended from 29 by chains 30, 30. As a result, the brake plates 28, 28 are arranged in an inclined state with the front side being higher and the rear side being lower with respect to the axial direction of the rollers 2, 3, 4, that is, the transfer direction in the transfer path 27. Each brake plate 28 is made of a plate-like material made of a flexible material that tends to maintain its inclined state at all times due to its own weight, and a brush 28a made of a resin material such as vinyl chloride is provided on its lower surface. of course,
A cushioning material such as rubber or sponge may be provided on the lower surface of each brake plate 28 instead of the brush 28a. Furthermore, above the front of the machine frame 1, there is a hopper 31 for feeding melons, etc.
The hopper 31 opens its discharge end to the transfer path 27. Further, a chute, a conveyor, etc. for conveying melons and the like discharged from the transfer path 27 are installed in series at the rear of the machine frame 1 as necessary.

In the cleaner for melons, etc., configured as described above, when melons, etc. are thrown into the front end of the transfer path 27 via the hopper 31, the bottom of the melons, etc. is supported by the receiving brush roller 2, and the rotating feed It is guided by the protrusion 3a of the brush roller 3 and moves to the rear of the transfer path 27. Accordingly, the brush of the rotating polishing brush roller 4 comes into sliding contact with the surface of the melon, etc., removes mud and the like adhering to the surface, and polishes the surface. During this time, even if melons, etc. move vertically or try to escape from side to side within the transfer path 27 due to the rotation of the rollers 2, 3, 4, etc., the braking plates 28, 2 provided above the transfer path 27
8 and the guide plate 26, the melons and the like smoothly move backward while rolling. In this case, when the moving melon etc. comes into contact with the brake plates 28, 28 which are tilted so as to gradually descend in the transport direction, the direction of rotation is changed, and as a result, the entire surface is uniformly polished by the action of the brush roller 4. will receive. In addition, when handling large melons, etc., the front lever 6 and rear lever 8 are adjusted so that the distance between the polishing brush roller 4 and the feed brush roller 3 is appropriate for the size of the melon, etc. If the size of the melon, etc. to be handled is small, the front lever should be adjusted so that the distance between the polishing brush roller 4 and the feed brush roller 3 is narrow enough to suit the size of the melon, etc. 6 and the rear lever 8 are integrally positioned, even if the size of the melon etc. is extremely large or small, it is possible to always apply an appropriate polishing action depending on the size of the melon or the like.

Furthermore, if there is relatively little dirt on melons, etc., and there is no need to polish the entire length of the rollers 2, 3, and 4, the distance between the inlet sides of the rollers 3 and 4 should be set to a width that allows for appropriate polishing action. By positioning the front lever 6 and positioning the rear lever 8 so that the distance between the rollers 3 and 4 on the exit side is wider than this, melons, etc. are subjected to the necessary and sufficient polishing action near the entrance. is moved at high speed without receiving resistance from the polishing brush roller 4, and therefore is discharged to the exit side in a shorter time than in the normal case, improving processing efficiency. In addition, if the melons, etc. are very dirty and need to be polished for as long as possible, the front lever should be adjusted so that the gap between the rollers 3 and 4 on the inlet side is as narrow as possible within the range where the melons, etc. can be introduced without any hindrance. 6 and position the rear lever 8 so that the distance between the rollers 3 and 4 on the outlet side is narrower than this, melons, etc. are introduced without any trouble to the inlet side and then move to the outlet side. It receives a large resistance from the polishing brush roller 4 that hinders its movement, and therefore it takes a longer time than usual to be discharged to the exit side.
During this time, sufficient polishing action will be applied.

As is clear from the above description, according to this invention, the distance between the polishing brush roller and the feed brush roller can always be adjusted to an appropriate width depending on the size of the melons, etc. being handled. For example, if there is relatively little dirt on melons, etc., adjust the interval to be narrower on the inlet side and wider on the outlet side, and apply the necessary and sufficient polishing action to the melons etc. near the inlet. It is possible to improve the processing efficiency by discharging to the outlet side in a shorter time compared to the above, and if the melon etc. are quite dirty, the above-mentioned interval can be adjusted to be wider on the inlet side and narrower on the outlet side. By allowing melons, etc. to enter the inlet side without any trouble and then preventing them from moving to the outlet side, it is possible to perform a sufficient polishing action over a longer period of time than in a normal case.
