Abstract

PROBLEM TO BE SOLVED: To release cleaning water to a large range by providing a high pressure cleaning nozzle with a motion means and a motion fulcrum of the motion means and by swing-moving the high pressure cleaning nozzle around the motion fulcrum. SOLUTION: A rear end of a motion plate 11 to which a cleaning nozzle 1 is mounted is journalled to a motion fulcrum 5, and a motion transmission shaft 13 is provided for the motion plate 11. The motion transmission shaft 13 is linked through a link mechanism 2 to a crank plate 12 mounted to a motor 8, and is pushed or pulled by the crank plate 12 rotating according to the motor 8. In other words, the link mechanism 2 converts rotational motion of the crank plate 12 to reciprocating motion of the motion transmission shaft 13. But, because the rear end of the motion plate 11 is positioned and fixed by the motion fulcrum 5, resultantly the cleaning nozzle 1 swing moves right and left around the motion fulcrum 5. Thus the cleaning nozzle l mounted to the motion plate 11 continues right and left swing motion.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an endless belt cleaning apparatus.

[0002]

2. Description of the Related Art For example, an endless belt attached to an open structure steamer or a cooler in the brewing industry is washed by rubbing with a channel brush or the like while applying washing water.
It was difficult to completely remove the residue that had entered the eyes of the belt. Further, a method of washing by removing the endless belt from a steamed rice mill or a cooler equipped with an endless belt (Japanese Patent Laid-Open No.
There is also a device that cleans the endless belt by discharging high-pressure cleaning water with a spray gun, but the former is troublesome, and the latter cannot be washed without missing the endless belt. Washing failed.

[0003]

In order to clean the endless belt in a sanitary manner, it is preferable to spray cleaning water at a high pressure to wash off the adhered residue. In this case, it is necessary to use a wide-angle cleaning nozzle or dispose a large number of cleaning nozzles in order to distribute high-pressure cleaning water throughout the endless belt width direction. If it is fixed, it requires a large amount of washing water,
There has been a problem that a sufficient cleaning effect cannot be obtained because the pressure of the cleaning water on the cleaning surface decreases. Therefore,
Even with a single cleaning nozzle having a narrow cleaning range, the first goal was to make it possible to realize a wide cleaning range effective as a cleaning device.

[0004] Further, if the cleaning device is provided with portability,
A single cleaning device can be allocated to a number of devices to be cleaned without using a cleaning device individually for each endless belt,
Capital investment can be reduced. Assuming portability, the power source for moving the cleaning nozzle is preferably lightweight, but it is desirable to avoid an increase in manufacturing cost. Therefore, in order to increase the convenience by adding portability to the cleaning device, the second goal was to reduce the manufacturing cost while reducing the weight.

[0005]

As a result of the study, an endless belt is provided in which a high-pressure cleaning nozzle is provided with a moving means and a fulcrum of the moving means, and the high-pressure cleaning nozzle swings around the fulcrum. Is a cleaning device. Since the movement of the cleaning nozzle in this cleaning apparatus is a swing motion centered on the fulcrum, the nozzle tip is directed in the radial direction, and the cleaning water can be discharged at a wide angle.

[0006] One or a plurality of cleaning nozzles may be grouped and integrally swung. The swing motion may include a reciprocating rotation (turning motion) in the same plane and a three-dimensional motion along a trajectory laid within a predetermined solid angle. As the swinging motion means, a means for converting rotational power into reciprocating motion by a link mechanism is conceivable. The fulcrum of movement may be a single fulcrum for the reciprocating rotation, but a flexible joint or the like may be used in the case of three-dimensional reciprocation. Further, the movement fulcrum may be a virtual point, and only the cleaning nozzle or the nozzle opening of the cleaning nozzle having no connection with the movement fulcrum may be swung.

[0007] Apart from the movement form of the cleaning nozzle,
If the cleaning means provided in the high-pressure cleaning nozzle is a motive means that uses the main stream or tributary flow of the cleaning water sent to the high-pressure cleaning nozzle as a power source, it is not necessary to separately add a power source such as an electric motor to the cleaning nozzle. Also, the cleaning nozzle can be caused to perform a reciprocating linear motion, a swing motion, and the like. The main stream of the washing water is a stream mainly intended to be discharged from the washing nozzle, and the branch stream is a stream mainly intended to be branched from the main stream and used as a power source. After being used as a power source, the tributary may be drained, or may be rejoined with the main stream and discharged from the washing nozzle.

[0008] Such a washing apparatus is provided with a mounting means for enabling the high-pressure washing nozzle to fix or move its position. The installation means here means, for example, the high-pressure cleaning nozzle, the swinging movement means and the movement fulcrum are integrally fixed to a device having an endless belt during cleaning (device to be cleaned), removed after cleaning, and removed from another device. From the simple ones such as fixing or releasing means that can be carried to the transportation to the transportation, it includes the ones having a trolley or a power for moving in the transportation. If the flow of the cleaning water is used as the power source of the moving means of the cleaning nozzle, the cleaning device can be reduced in size and weight, and can be transported by an operator. By disposing a supply device (such as a hose) that sends cleaning water to the cleaning device near the device to be cleaned, it is not necessary to provide a separate cleaning device for each device to be cleaned simply by moving the cleaning device. In addition, capital investment can be minimized.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the cleaning apparatus of the present invention, and FIG. 2 is a partially enlarged plan view showing the vicinity of a cleaning nozzle 1 and a link mechanism (swinging motion means) 2 of the cleaning apparatus. FIG. 3 is an enlarged plan view of the same portion showing the cleaning nozzle 1 swung from the state of FIG. As shown in FIG. 1, the cleaning device of this example has a support 4 erected on a trolley 3 as a mounting means capable of being fixed and released and movable, and a base 6 having a movement fulcrum 5 at the upper end of the support 4. The cleaning nozzle 1 having four nozzle ports 7 is swung right and left in a horizontal plane with respect to the base 6. The base 6 is provided with a motor 8 for generating rotational power. The link mechanism 2 converts the rotational power into a left and right swing motion. A separately prepared water supply hose 9 is connected to the washing nozzle 1 to send washing water, and branches to each nozzle port 7.

The cleaning device of this embodiment converts the rotational power of the motor 8 into a swing motion of the cleaning nozzle 1 as follows.
As shown in FIG. 2, the rear end of the motion plate 11 to which the cleaning nozzle 1 is attached is pivotally mounted on the motion fulcrum 5, and the motion plate 11 is provided with a motion transmission shaft 13. This motion transmission shaft 13
Is connected to the crank plate 12 attached to the motor 8 by the link mechanism 2, and is pushed and pulled by the crank plate 12 that rotates according to the motor 8. That is, the link mechanism 2 converts the rotational motion of the crank plate 12 into a reciprocating motion of the motion transmitting shaft 13. However, since the position of the movement plate 11 is fixed at the rear end by the movement fulcrum 5, as a result, the cleaning nozzle 1 swings right and left around the movement fulcrum 5.

When the motion transmission shaft 13 continues to reciprocate further from the state shown in FIG. 2, the motion plate 11 reverses the direction of motion and reaches the state shown in FIG. As described above, the cleaning nozzle 1 attached to the exercise plate 11 keeps swinging right and left. The swinging motion of the cleaning nozzle 1 is a sine wave that decelerates right and left from the center of the swinging motion even if the circular motion of the crank plate 12 is constant. As a result, the discharge time of the cleaning water at the left and right ends far from the cleaning nozzle 1 is long, and the discharge time of the cleaning water is short on the short center line, and the discharge of the cleaning water is substantially uniform in the cleaning range. Realize.

Next, a case in which the flow of the washing water is used as rotational power will be described. FIG. 4 is a partial cutaway view of the link mechanism 2 showing an example in which a water motor 15 is rotated by using a flow (main flow) 14 of cleaning water sent to the cleaning nozzle 1 to obtain rotational power, and FIG. The flow (main stream) 14 of the washing water to be sent to 1 is branched, the main stream 14 is sent to the washing nozzle 1, the tributaries 16 are sent to the water motors 15 and 15, and the water motor 1
FIG. 6 is a partially broken configuration diagram of a link mechanism 2 illustrating an example of obtaining rotational power by rotating 5, 5; The example of FIG.
A water motor 15 is provided in the middle of the path of the washing water flowing to the washing water, and the water motor 15 is rotated by the flow 14 of the washing water to obtain rotational power. On the other hand, in the example of FIG. 5, the water motor that branches the cleaning water sent to the cleaning nozzle 1 and meshes on the path of the tributary 16
Two water motors 15 and 15 are provided, and the water motors 15 and 15 are rotated by the pressure of the tributary flow 16 flowing into the portion where the water motors 15 mesh with each other. This tributary 16
May be drained after being used as a power source, or may be re-joined to the main stream 14 and discharged as washing water.

The usage of the cleaning apparatus illustrated in FIG. 1 will be described. FIG. 6 is a side view showing a state in which the discharge port 18 side of the continuous pressurizing device 17 is opened, and the cleaning device is installed and cleaned so that the cleaning nozzle 1 faces the built-in endless belt 19. As described above, the cleaning device of this example is provided on the trolley 3 as an installation means, is freely movable, and fixes the position of the trolley 3 to facilitate installation for cleaning. The position of the cart 3 is fixed by a stopper to the floor, a bolt (not shown) provided on the cart 3 and a bolt or a clamp for connecting and fixing to a device to be cleaned. When a bolt, a clamp, or the like is used as the installation means, in the example of FIG. 1, a flange may be provided on the base 6 having the fulcrum 5, and the position of the base 6 may be directly fixed to the apparatus to be cleaned.

When cleaning the endless belt 19, the cleaning nozzle 1 is swung while operating the motor 8 to discharge the cleaning water. At this time, the endless belt 19 is operated (FIG. 6).
(See the bold arrow.) And the endless belt 19 can move the dirty portion toward the cleaning nozzle 1, move the portion that has already been cleaned away from the cleaning nozzle 1, and discharge the dirty water or residue 20 from the discharge port 18. Can be removed to the outside. After washing
The position fixation of the carriage 3 is released again so as to be movable, and the cleaning device can be carried to another device to be cleaned and used for the next cleaning. In this cleaning apparatus, the cleaning water and the electric power of the motor must be supplied from the existing equipment. However, moving only the cleaning apparatus enables cleaning of a plurality of apparatuses to be cleaned.
Furthermore, the cleaning device using the water motor described above can reduce the weight and facilitate the movement, simplify the structure and improve the maintenance, and can save power by not using electric power.

The swing motion in the cleaning device of the present invention is as follows.
Not only the left and right swing motion in the horizontal plane described above, but also a three-dimensional motion including up and down swing motion and up, down, left and right. FIG. 7 shows the outer periphery of the disk 21 as the sliding contact track 22.
FIG. 3 is a perspective view showing a state in which a cleaning nozzle 1 having a base nozzle port 7 is three-dimensionally swung. The means for displacing the washing nozzle 1 depends on a link mechanism (not shown), but as shown in FIG. 7, the movement fulcrum 5 can be freely rotated by using a flexible fulcrum 5 as a flexible joint, and the rotating surface of the rotating power is made vertical. Thus, it is possible to cause the cleaning nozzle 1 to perform a three-dimensional swing motion including up, down, left, and right.

[0016]

Next, a test was conducted to confirm the effect of cleaning by the cleaning apparatus of the present invention. The cleaning device is a straight type,
A prototype of a cleaning nozzle having one nozzle port having a capacity of 38.1 L / min. (At 50 kg / cm ² ) that swings in a horizontal plane was manufactured. As a device to be washed, a continuous pressure steaming device for steaming soy sauce defatted soybeans was selected, and the steaming pressure was 2 kg / cm ² , 4 t /
After operating for 3 hours at h, the cleaning by the cleaning device was attempted. At the time of washing, the endless belt of the steaming apparatus was operated at 16 mm / sec., And the washing nozzle was swung at 60 reciprocations / min. When the result of the washing was confirmed, no residue was seen on the endless belt, and it was confirmed that the endless belt was thoroughly washed.

[0017]

According to the cleaning apparatus of the present invention, the cleaning nozzle having realized the swinging motion can discharge the cleaning water to a wider range, and the cleaning of the endless belt can be effectively performed. In addition, when a water motor is used as a power source of a cleaning nozzle that performs a reciprocating motion and a swinging motion, the weight of the cleaning device can be reduced while suppressing manufacturing costs. Then, by providing the high-pressure cleaning nozzle with a mounting means capable of fixing or moving the position, easy portability of the cleaning device is realized, and the above-described efficient cleaning can be provided to a plurality of devices to be cleaned. It becomes.
