Description

Detailed Description of the Invention <Industrial Application Field> The present invention relates to a method for manufacturing a dust control product, and more specifically, a method for manufacturing a dust control product, in which washing, oil impregnation, and dehydration steps can be performed in one device. By having a dehydration processing machine and using the washing and dehydration processing machine, and also using a dryer, centrifugal force is used to uniformly and completely impregnate the entire fiber with the oil agent. The present invention relates to a method for manufacturing dust control products.

<Conventional technology> Many conventional technologies have already been provided for the production of dust control products such as motu, mat, and cloth, but none of these technologies have the ability to adsorb oil in the manufacturing process. It was customary to use a separate suction processing machine. In the case of processing using such an adsorption processing machine, the oil is usually sprayed after drying, so for example, the amount of adsorbent at the tip and surface of the motsu pile tends to become oil-rich, and the base part tends to become oil-rich. It was difficult for the oil to penetrate sufficiently, and it was also difficult to penetrate the oil evenly. Another example is a manufacturing process in which oil is sprayed on a belt conveyor after drying, but since the oil was sprayed in the form of a mist in the factory, the oil may scatter into the air. It could not be said that a sufficient working environment had been secured for the workers on site.

Next, to give a concrete example of the prior art, there is an "oil agent spraying device" (Utility Model Publication No. 40702/1983). In other words, ``The oil spraying device of this invention includes a rotary drum that is driven to rotate, an inlet/outlet hole in one side wall, and a lid body that can seal the inlet/outlet hole, and furthermore, a The gist thereof is to include a casing supported tiltably relative to a base, and a spray nozzle for spraying an oil agent into the rotating drum of the casing.

With such a configuration, when spraying the oil onto the rag, the casing, that is, the rotating drum is rotated in a horizontal state, and the oil is sprayed by the spray nozzle. When taking out the rag after spraying, the lid is opened, the casing is tilted, and the rotating drum is rotated, so that the rag is sequentially discharged from the inlet/outlet hole.

<Problems to be Solved by the Invention> However, this technique has a serious drawback in that the oil is applied unevenly and excessively only to the tips and surfaces of fibers such as mops. However, as can be easily understood by looking at the structure of the spraying device, this technique relies solely on the so-called capillary phenomenon to diffuse the oil agent throughout the fibers.
In addition, since the spraying device according to the invention is an independently necessary device whose purpose is only to spray the oil,
A series of steps necessary for manufacturing, namely washing, rinsing,
When considering dehydration, it is pointed out that there is a large time loss, and problems such as securing space for installation, the need for transportation equipment to equipment before and after the production line, and securing personnel for this purpose have been pointed out. was. As described above, in this invention, the oil adsorption processing device was a separate and independent unit, but in the present invention, since it is used as an integrated device, the adsorption processing device is a separate and independent unit. It is possible to avoid the need for In the prior art, the quality of the manufactured object is limited, or it is impossible to uniformly and completely adsorb large or cross-shaped objects. However, in the conventional technology, the oil agent was sprayed after drying, which is the final step of manufacturing, but in the present invention, the oil agent is sprayed in the wet state, and by using the centrifugal force caused by the rotation of the drum. By utilizing the difference in specific gravity between water and oil, the fibers are impregnated with oil evenly and completely. The meaning and rationale for using centrifugal force here is that even if the spray state of the oil agent is rough or uneven to some extent at first, by applying centrifugal force, the oil agent adhering to the fibers can be sprayed from areas with a high concentration of oil agent. This method utilizes the movement of the oil to evenly distribute it on thin areas.

As described above, the present invention provides a manufacturing method that includes an innovative oil adsorption process for improving the working environment, streamlining the manufacturing process, and saving labor when manufacturing dust control products.

<Means for Solving the Problems> The constituent elements of the method for manufacturing a dust control product according to the present invention are that a drum that is rotatably driven is installed in a case-like machine frame, and a sealable opening/closing device provided in the case-like machine frame. A spray nozzle for spraying oil is provided through the door or shaft, and a laundry dehydration processing machine is connected to this spray nozzle via a hose with a spray valve to wash laundry, impregnate it with oil, and dehydrate it. After that, the laundry is dried using a dryer and the oil is uniformly dispersed.Specifically, its features are as follows. Oil tank with heating function (heating device with constant viscosity to control discharge amount at a constant rate). Oil supply pump from oil tank.
Spray nozzle and spray piping. A device with a solenoid valve, flowmeter, and sequencer that controls the amount of spray for each product. A device that controls drum rotation and centrifugal force during oil spraying. In the manufacturing process, a laundry dehydration processing machine that can perform the steps of washing, oil impregnation, and dehydration in one device. It consists of the above-mentioned components such as a dryer necessary for the final process of manufacturing.

Hereinafter, the present invention having such characteristics will be explained in detail with reference to the accompanying drawings.

FIG. 1 and FIG. 2 are explanatory diagrams showing the entire washing and dehydrating processing machine in the method of manufacturing a dust control product according to the present invention. A case-like machine frame 1 houses a drum 2 that is rotatably driven. That is, the drum 2 having a large number of punch holes 25 that is rotatably driven is disposed within the case-like machine frame 1 fixed to the frame body 26. During washing, as a result of water entering the case-like machine frame 1, water also enters the drum 2 through the punch holes 25. A case-like machine frame 1 is provided with a sealable opening/closing door 3, and a spray nozzle 5 connected to a hose 4 is installed in this opening/closing door 3. This spray nozzle 5 may be connected to the opening/closing door 3, but it can also be installed via the shaft 15. Such a spray nozzle 5 is for spraying oil into the drum 2. As the drum 2 rotates, the laundry 23 to be manufactured also rotates at high speed, but at this time, the laundry 23 manufactured in the drum 2 rotates at high speed. Since there is a risk that motsus, etc. that are floating may get caught in the protruding part of the spray nozzle 5 as the drum 2 rotates (when the spray nozzle is installed on the opening/closing door), a nozzle cover 6 is provided to prevent the spray nozzle 5 from getting caught. That part is prevented from protruding directly into the drum 2. Also, the spray nozzle 5 is connected to the drum 2.
However, the location and angle at which it is installed is very important as it is necessary to spray the oil evenly. Therefore, when installing the spray nozzle 5, it is effective to set the position and angle so that the spray nozzle 5 can completely cover one side wall surface having the punch holes 25 in the drum 2. If the angle or position is incorrect, it will be difficult to spray the oil uniformly.
This spray nozzle 5 is connected to a hose 4 for sending the oil from an oil tank 8, which has a check valve 7 provided to prevent backflow of the oil. The hose 4 is provided with a spray valve 9 which is an electromagnetic valve and also serves as a control valve for adjusting the flow rate of the oil to a specified value at a midway point of the hose 4, and the other end thereof is connected to the oil tank 8. This oil tank 8 is a tank for storing and holding oil, but if an automatic liquid level control device is separately set in the oil tank 8, when the remaining amount of oil gets low, the separately installed This oil tank 8 can be constantly replenished with a constant amount from the auxiliary tank. 10 is a pump for sending out the oil and controlling the flow rate, and 11 is a pump that maintains the viscosity of the oil at a constant level and supplies the oil stably even when the location is in a cold region. The pre-heater 12 is a switching valve, and the switching valve 12 normally operates during washing or rinsing, even in cold regions.
As the temperature drops, the amount of oil sprayed may vary,
Preheater 1 to prevent the viscosity of the oil from increasing
This valve allows the pump 10 to circulate the water while allowing the water to pass through. An oil temperature control device is set in the preheater 11. The need for temperature control is
If there is a temperature difference in the oil, the viscosity of the oil itself will change, and this is to prevent this and equalize the amount of spray. Note that 13 is a flow meter for determining and checking a predetermined spray amount for each quality, and 14 is an air tank that functions to send out an accurate amount of oil. Also,
24 control panels control the flow rate of oil for each product,
It is used to determine whether or not it is necessary to spray oil, or to function as a signal in the event of trouble. Further, 22 is a strainer, and this strainer 22 is a filter for removing dust, so to speak, a filtration device.

FIG. 3 shows a sectional view of essential parts of a washing and dehydrating processing machine 30 according to the present invention. The drum 2 is a case-like machine frame 1
It's decorated. The rotationally driven drum 2 is connected to a shaft 15 that is fixedly integrated with a pulley 27. Note that the pulley 27 is connected to a motor via a belt. 16 is an inner bearing and 17 is an outer bearing. Both bearings 16 and 17 are used to smoothly rotate the shaft 15 for stably rotating the drum 2. Further, 18 is a drainage tank for use during dehydration. This tank is a drainage tank that has a structure in which a valve opens during drainage, allowing drainage. In addition, 3
2 is a drain valve.

In the present invention, the washing and dehydrating processing machine 3
It also has a structure to prevent vibration during operation. In other words, 19 is a hydraulic damper, which is used to absorb vibrations during washing, and is a so-called shock damper.
It is an absorber. In addition, 20 indicates a front air ride, and 21 indicates a rear air ride.
It works to make the shock more uniform by making it float, and to soften it. By mutually functioning these hydraulic dampers 19 and the front and rear air rides 20, 21, it is possible to minimize vibrations during manufacturing operations. In addition, 26
is a frame body that holds the entire main washing and dehydrating processing machine 30.

After washing, dehydration, oil spraying, and high-speed dehydration using the laundry dehydration processing machine 30 having such a configuration, the laundry 2 is removed from the airtight outlet 31.
3 is taken out, conveyed by a belt conveyor 29, and then placed in a dryer 28 for drying treatment. Incidentally, since it is effective when taking out the laundry 23 from the washing and dehydrating processing machine 30, it is effective to accompanies a device that allows the washing and dehydrating processing machine 30 to tilt (not shown). As described above, in the present invention, the oil agent is sprayed in the drum 2 in a state where the laundry 23 itself contains sufficient moisture to ensure uniform impregnation of the oil agent. By rotating at high temperature, the distribution state of the oil agent can be made more completely uniform. This is because when the water adhering to the laundry 23 is scattered in the dryer 28 during drying, only the oil component is diffused throughout the fibers of the laundry 23.

Incidentally, FIG. 4 is an explanatory diagram briefly showing the manufacturing process in the method for manufacturing a dust control product according to the present invention. That is, the laundry 23 is processed before the drying process in the washing and dehydrating processing machine 30, and then the laundry 23 is taken out, placed on the belt conveyor 29, conveyed, dried, and placed in the drying process 28 to complete the drying process, resulting in a dust control product as a whole. The manufacturing process is completed.

The method for manufacturing a dust control product according to the present invention is comprised of the above-mentioned constituent elements, and next, a brief explanation will be given of an actual usage example.

First, the power is turned on and the oil is heated by the preheater 11 to keep the oil temperature constant. Then, the opening/closing door 3 is opened and the dirty laundry 23 is put into the drum 2.
Then, by pressing the start button, the automatically set hot water flows into the drum 2. When the warm water reaches the specified water level, the detergent will enter.
Washing begins. And after the rinsing process,
Drainage takes place. This process is repeated several times. Then, the dehydration process begins. In this dehydration process, the process of spraying the oil agent while draining the water in the drum 2 is repeated several times. Then, while controlling the centrifugal force accompanying the rotation of the drum 2, water remaining in the fibers of each laundry 23 is then removed by high-speed rotation. In this way, in the present invention, the oil agent is sprayed during the dehydration process when the laundry 23 itself is sufficiently hydrated, rather than after the laundry 23 has finished drying, and the centrifugal force generated by the rotational force of the drum 2 is applied. Since we are using , due to the synergistic effect. The amount of sprayed oil used can be reduced, and... Even among a large number of laundry items 23 that are washed together in one drum 2, the laundry items 23 come into contact with each other and press each other, so that the spray of the oil itself is distributed very uniformly. ,Also,. Even if the laundry 23 is something like a mop, the surface and inside, and the outside and center of the mop itself can be uniformly impregnated with the oil agent. This will also be explained in a little more detail. That is,
Since the variation in the amount of oil contained in the product is reduced, the amount of oil required to impart the performance of the dust control product approaches the theoretical setting value, so the additional oil that was added to account for processing variations is no longer necessary. Therefore, the amount of oil used can be reduced.
In addition, when using the rotating drum 2 with punch holes 25 for washing and rinsing, oil is usually sprayed during two rotations of the washing drum, so the oil flows out from the opening of the punch holes 25, so-called oil loss. It causes. To improve this point,
When balancing the washing and dehydrating processing machine 30 (for example, by pasting a laundry barrel on the inside of the drum and filling the punch hole opening with the motsu layer = a state in which centrifugal force and gravity are in balance), the oil agent can be sprayed. Due to the difference in specific gravity between the oil and water, the oil remains and only the water is discharged. next,. When using the balancing spray, the oil agent is sprayed only on the surface of the laundry 23, for example, the mop layer, so a loosening process for the laundry 23 is added, and the balancing spray and loosening processes are repeated 4 to 9 times. By repeating this process, the oil can be evenly dispersed between the mops. lastly,. As a result of performing high-speed centrifugal dehydration, the centrifugal effect causes the uniformity of the motsu individually and between motsu, and the dispersion of oil between the tip and root of the pile disappears, resulting in stickiness on the motsu pile surface (oil-rich state). is improved.

Next, the remarkable effects of the present invention will be explained with reference to experimental examples.

<Experimental Example 1> Figure 5 shows the state of the oil content at the tip and base of motsuppai after being treated for 15 minutes. The ratio of oil content is expressed as (oil content at the base/oil content at the tip) x 100.

FIG. 6 shows the oil content at the tip and root of the motsupile before and after centrifugation.

As can be understood from these drawings, it was found that centrifugal force causes the oil agent with high oil content to diffuse in a lower direction, causing the oil content to migrate in the direction of averaging, thereby achieving uniformity.

<Experiment Example 2> Next, using the method of manufacturing a dust control product by adsorption processing of an oil agent using centrifugal force according to the present invention, the oil content of the oil agent was examined using various types of laundry manufactured. Furthermore, Fig. 7 is an example using a small motsup, Fig. 8 is an example using a cloth, Fig. 9 is an example using a large motsup, and Fig. 10 is an example using a chemical fiber motsup. Examples using each are shown below.

<Effects of the Invention> The method for manufacturing a dust control product according to the present invention is configured using a so-called centrifugal dehydration oil impregnation method that utilizes the specific gravity difference in centrifugal dehydration as described above, so when manufacturing motsupu or cloth. ,
Conventional processing methods, including equipment that sprays oil on a belt conveyor after drying, spray oil in the form of a mist only on the surface and tip of the mop or cloth, resulting in the finishing worker being exposed to oil. However, according to the present invention, there was no stickiness caused by the oil, and the working environment was significantly improved. However, in the present invention, since the oil agent is sprayed onto the mop etc. in a water-containing state, there is no scattering of the oil agent and there is no deterioration of the manufacturing environment at all. Additionally, since the spray is not a mist but a liquid, the working environment can be greatly improved.

Next, according to the present invention, there are no restrictions on the types of objects to be manufactured. Specifically, in the conventional method, when the material was cotton, internal penetration into the fibers could be expected, but when using chemical fibers, they had a very sticky feeling and were difficult to use. However, according to the present invention, even chemical fiber mops can be processed very easily and uniformly, and can be evenly impregnated with an oil agent, thereby greatly expanding the range of application.

In addition, in the conventional technology, spraying is performed after drying, so it is impossible to spray uniformly on objects such as large motsus or cloth.
In the present invention, there is no such restriction and spraying can be performed uniformly.

Further, in the present invention, since the adsorption of oil to the fibers can be processed within the washing and dehydrating processing machine, there is no need for an independent adsorption processing device, and there is no need for special costs or installation space.

In addition, when the manufacturing method according to the present invention is adopted, the variation in the amount of oil contained in the product is reduced, so the amount of oil required to impart performance to the dust control product approaches the theoretical setting value. The oil that had been added in consideration of this became unnecessary, and the amount of oil used could be reduced.

Furthermore, by using the present invention, effects such as equalizing the line balance in the manufacturing process and facilitating automation and labor saving can be expected, and the above-mentioned objects of the present invention can be fully achieved.
