Description

The present invention relates to a cleaning sponge and its manufacturing apparatus. Specifically, a large number of diamond-shaped notches are aligned on the cleaning surface of the cleaning sponge, and the directions of the long diagonal lines of the rhombus are different on both sides of the cleaning surface. The present invention relates to a manufacturing apparatus suitable for processing such a notch by changing the contact resistance.

Automobiles and tableware are frequently washed with water, and there are concerns about cleaning scratches caused by the friction generated by tools such as sponges used for cleaning. Especially in automobiles, dark-colored cars such as black are prone to cleaning scratches, and transparent glasses are cloudy. Therefore, for example, when cleaning a luxury car, use a sponge, mouton, or a special cloth such as microfiber to clean it, and then wipe off the water with a towel, microfiber cloth, synthetic chamois, chamois, etc. to remove scratches. Great care is taken. However, at the time of cleaning, car shampoo is often applied to a cleaning sponge or the like to remove stains, and at that time, sand or the like is taken into the surface of the sponge and it is easy to make cleaning scratches. In order to prevent scratches during cleaning as much as possible, pre-washing with a high-pressure washer adjusted to a water pressure suitable for cleaning will prevent scratches as much as possible, but it is not enough. Since the stuck dirt cannot be completely removed, it is necessary to use a sponge or mouton to scrape off the dirt. The tools and friction used when scraping off are the most common cause of cleaning scratches, but as a countermeasure, pay attention to the selection of the material of the tool itself and reduce the friction as much as possible to prevent cleaning scratches. It is possible to prevent it as much as possible. It also meets the needs of preventing scratches during cleaning as much as possible in order to maintain the brilliance of new products for expensive items such as automobiles and tableware.

Therefore, in view of such a problem, various technical proposals have been made conventionally. For example, a technique in which the title of the invention is "cleaning sponge" is disclosed (see Patent Document 1). Specifically, the subject is "to provide a car wash sponge that can prevent the cleaning surface from being scratched and prevent the protrusions on the cleaning surface from injuring hands and fingers." As a solution, "on the upper surface and the lower surface of a rectangular parallelepiped sponge body made of a flexible synthetic resin foam, in a parallel line shape maintained at a constant interval with respect to the center of two pairs of diagonal lines, respectively. There are a plurality of cuts that maintain the depth of the above, and the cuts are invisible in a state where the cut edges are in close contact with each other and the rectangular parallelepiped sponge body itself made of the synthetic resin foam is not deformed. In addition, by intersecting these cuts, a plurality of uniform rhombic shapes are formed on the upper and lower surfaces of the rectangular parallelepiped sponge body, and two types of multiple isosceles with different internal angles on the long and short sides of the rectangular parallelepiped sponge body. An invention of "a car wash sponge characterized by forming a triangular shape" has been published and has become a known technique. The techniques described in Patent Document 1 are common in that they include slits that form a rhombus shape. However, the technique described in the prior art 1 changes the contact resistance to the object to be cleaned, and it is not possible to appropriately use a good surface to be cleaned according to the condition of the surface to be cleaned. The problem of the present invention that makes this possible has not been solved yet.

Further, a technique in which the title of the invention is "cleaning sponge" is disclosed (see Patent Document 2). Specifically, "a car wash sponge that makes it possible to prevent the car wash sponge from dropping on the ground or damaging the washing surface, and also preventing the protrusions on the washing surface from injuring hands or fingers. As a solution, "the diagonal lines of the upper and lower surfaces of the flexible rectangular sponge body are used as a reference, and the intervals are fixed with respect to the diagonal lines." The upper surface and the lower surface of the sponge body are provided by crossing a plurality of cuts that maintain a certain depth in which the invisible cut edges are in close contact with each other in a parallel line shape that maintains the above. The car wash sponge is characterized by having multiple uniform diamond-shaped shapes with invisible cut edges and a fall prevention band that prevents the car wash sponge from dropping on the ground. " The invention has been published and has become a publicly known technique. The techniques described in Patent Document 2 are similar to the techniques described in Patent Document 1 in that they include slits forming a rhombus shape. However, the technique described in the prior art 2 changes the contact resistance to the object to be cleaned, and it is not possible to appropriately use a good surface to be cleaned according to the condition of the surface to be cleaned. The problem of the present invention that makes this possible has not been solved yet.

Further, a technique in which the title of the invention is "car wash sponge" is disclosed (see Patent Document 3). Specifically, the problem is "to provide a car wash sponge that can enhance the washing ability as well as the durability of the car wash sponge." As a solution, a groove-shaped cushioning ring is heat-melted on the surface of the sponge. Formed at. A buffer ring is formed at a position away from the joint between the sponge and the handle. A buffer ring is formed at a position surrounding the joint. Place a cushioning ring around the side of the sponge. A grid-shaped cleaning groove is formed on the cleaning surface of the sponge. The cleaning groove is formed by heat melting means. The idea is open to the public and has become a publicly known technology. However, the technique described in Patent Document 3 is laborious and costly, such as forming a groove-shaped cushioning ring on the surface of the sponge by using a heat melting means, and is economically burdensome.

The present invention advances the conventional cleaning sponge with a slit to a more convenient one, and by changing the cleaning surface, the contact resistance to the object to be cleaned changes, and the object to be cleaned changes. We provide a cleaning sponge with slits that enables the proper use of the cleaning surface according to the condition of the surface to be cleaned, and the slits are placed on the top and bottom of the soft urethane foam that is the material, in different directions. An object of the present invention is to provide a dedicated device for cutting so that a large number of shapes are aligned.

A slit is cut in the bottom surface so that the diamond shape is continuous, and in the diamond shape, the lengths of the diagonal lines connecting the facing vertices are different, and the long diagonal line and the short diagonal line are orthogonal to each other. The diamond shape provided in the above is a device for processing the long diagonal line and the short diagonal line in different orthogonal directions, and is a base, a plurality of rotary blades mounted on the base, and the rotation. A motor that drives the blade, a slide guide that slides the cleaning sponge, a slide bed that guides the slide of the slide guide, a pressing mechanism that presses the cleaning sponge, and a control that controls the rotation speed of the motor. It is also possible to adopt a configuration in which the slide guide comprises a portion and the slide guide guides the orthogonal angle between the long diagonal line and the short diagonal line with respect to the slide bed.

According to the slitted cleaning sponge according to the present invention, since the directions of the diamond shapes formed on the upper surface and the bottom surface are different, the contact resistance of the cleaning surface is different, and cleaning that removes stubborn stains and attention to the delicate surface are performed. It has an excellent effect of being able to be used properly and cleaning.

Further, according to the slitted cleaning sponge according to the present invention, by using a material softer than the commonly used general-purpose urethane foam having a hardness, the function of taking in and discharging minute relics by the slit is obtained. It exerts an excellent effect of being able to exert.

Further, in the slit-filled cleaning sponge according to the present invention, when the material is specified as 2007S, it exhibits more excellent cleaning power, and has an excellent effect that a soft and chewy cleaning sponge can be obtained. It is something to demonstrate.

It is a basic structure explanatory drawing explaining the basic structure of the cleaning sponge with a slit which concerns on this invention. It is an Example explanatory drawing which shows the Example which provided the rhombus-shaped slit on the side surface in addition to the upper surface and the bottom surface in the cleaning sponge with a slit which concerns on this invention. It is a function explanatory drawing explaining the intake and discharge state of a minute foreign substance by the slit which concerns on this invention. It is a basic structure explanatory drawing which shows the basic structure of the device for exclusive use of slit processing of the sponge for cleaning with a slit which concerns on this invention.

The present invention is a substantially rectangular parallelepiped cleaning sponge composed of a top surface, a bottom surface, and a side surface, and the widest facing top surface and the bottom surface are provided with slits cut so as to have a continuous diamond shape. In the rhombus shape, the lengths of the diagonal lines connecting the opposite vertices are different, and the long diagonal line and the short diagonal line are orthogonal to each other. By rotating the direction perpendicular to the short diagonal line by 90 degrees and making it different, the contact resistance to the object to be cleaned is different between the upper surface and the bottom surface, and it is the maximum that it is a dedicated device that can process the slit. It is a feature of. Hereinafter, description will be given based on the drawings. However, the shape and structure are not limited to those described in the drawings, and the changes can be made within the range in which the effect exerted as the creation of the technical idea of the present invention can be obtained.

1A and 1B are basic configuration explanatory views illustrating a basic configuration of a cleaning sponge with slits according to the present invention, FIG. 1A is an overall configuration perspective view, and FIG. 1B is a plan view on the upper surface. The state of the slit cut is shown, and FIG. 1 (b) shows the state of the slit cut in the bottom surface as viewed from the bottom.

The cleaning sponge 1 with slits is provided with slits cut in the upper surface 10 and the bottom surface 20 of a substantially rectangular parallelepiped urethane foam to form a plurality of continuous rhombus shapes, and the materials are 2007S, 2005S, and 2007SK shown in Table 1. Is preferable, and it can be said that 2007S is the most suitable. The size is not particularly limited, but in general, if it corresponds to a wide area such as an automobile or a bathtub, it is preferably about 200 mm × 130 mm × 30 mm in consideration of the size of the palm. What is important here is the dimension in the thickness direction particularly on the side surface 30 connecting the upper surface 20 and the bottom surface 20. This is because if it is too thick, it is difficult to follow the shape of the object to be cleaned, and if it is too thin, the stiffness is lost and the force cannot be effectively transmitted to the cleaning surface. In addition, the thickness of 30 mm penetrates into the gap of the door visor attached to the upper part of the front door of the car, the base of the door mirror, the space between the bonnet and the windshield, etc. It becomes possible to wash with. In addition, since it is a rectangular parallelepiped, the sponge can reach and contact every corner of each corner using the corners, so it is possible to clean the part where dirt is most difficult to remove.

The upper surface 10 is one of the two surfaces having the largest area of the rectangular parallelepiped, and is the upper surface shown in FIG. 1 (b).

The bottom surface 20 is one of the two faces having the widest area of the rectangular parallelepiped, and one of the two faces having the widest area of the rectangular parallelepiped, and is the bottom side shown in FIG. 1 (c). Is the face of.

The side surface 30 is a surface in which the upper surface and the bottom surface are connected in the thickness direction, and is a surface around which the upper surface and the bottom surface are provided as shown in FIG. 1 (a).

The rhombus shape 40 is formed by slits 50 cut so as to be continuous, and the shape is such that the lengths of the diagonal lines connecting the facing vertices are different, and the long diagonal line L and the short diagonal line D are orthogonal to each other. The upper surface 10 and the bottom surface 20 are characterized in that the long diagonal line L and the short diagonal line D are rotated by 90 degrees in a perpendicular direction to be different from each other.

The slit 50 is a notch for forming the diamond shape 40. In the example in which urethane foam 2007S was used as the material of the cleaning sponge, the depth of cut was preferably in the range of 2 mm to 4 mm, more preferably 3 mm. This is because if it is shallower than 2 mm, it is difficult to take in minute impurities and the like into the slit 50, and if it is deeper than 4 mm, it is difficult to discharge the taken-in minute impurities and the like from the slit 50.

As shown in FIGS. 1 (b) and 1 (c), the long diagonal line L is the diagonal line having the longer length among the diagonal lines connecting the vertices facing each other in the diamond shape 40. be.

The short diagonal line D is the diagonal line of the diagonal line connecting the vertices facing each other in the diamond shape 40, whichever is shorter, as shown in FIGS. 1 (b) and 1 (c) with a difference of 90 degrees. be.

FIG. 2 shows an example in which a slit 50 having a diamond shape 40 is provided on the side surface 30 in addition to the upper surface 10 and the bottom surface 20, FIG. 2A is an overall perspective view, FIGS. 2B and 2 (FIG. 2). c) shows the side surfaces of the upper surface 10 and the bottom surface 20 corresponding to the long side and the short side, respectively. By having the slit 50 forming the rhombus shape 40 on the side surface 30, the side surface 30 can be used as a cleaning surface even when polishing a narrow gap, and in this case, the slit 50 of the rhombus shape 40 faces one side. The diamond shape 40 provided on the side surface 30 and the diamond shape 40 provided on the other side surface 30 that opposes each other have a 90 degree difference in the orthogonal direction between the long diagonal line L and the short diagonal line D. Therefore, it is possible to use it properly for the case of heavy dirt and the case of light dirt. Depending on the degree of dirt, it can be used according to the degree of dirt, depending on the degree of dirt, depending on the degree of dirt, depending on the degree of dirt, depending on the degree of dirt, depending on the degree of dirt, depending on the degree of dirt, depending on the degree of dirt, depending on the degree of dirt, depending on the degree of dirt, depending on the degree of dirt, depending on the degree of dirt, depending on the degree of dirt, the case of dirt with a lot of sand etc. sticking to the painted surface and easy to get friction scratches, and the case of light dirt with little sticking of dirt and dust on it. It is possible to prevent scratches due to cleaning.

FIG. 3 is a functional explanatory view illustrating a state in which minute foreign substances are taken in and discharged by the slit according to the present invention, and FIG. 3A is a slit in which the cleaning surface is moved in one direction while being in contact with the object to be cleaned. 3 (b) shows the state of the slit moved in the direction opposite to that of FIG. 3 (a), and FIG. 3 (c) shows the state of the minute foreign matter B taken into the gap of the slit. It shows the state. In each case, the slit is cut in the range of 2 mm to 4 mm, so that the taking-in function and the discharging function are exhibited, and cleaning scratches are not generated as much as possible. Further, in FIG. 3D, the diamond-shaped shape is a cleaning sponge.

Table 1 is a table showing the physical properties of the material of the cleaning sponge, and is a comparative study of six types of urethane foam materials that are considered to be suitable for the cleaning sponge. It is better to be soft so as not to damage it, but if it is soft, the waist will come off easily and processing will be difficult. On the other hand, if it is hard, it is easy to process and has a waist, but it is easy to leave cleaning scratches on the object to be cleaned. The targets of comparison were 2007S, 20M, 2005S, 2007SK, 20S, and 20SS. Among them, 2007S was the softest but had a moderate waist and showed the most ideal physical properties including workability. The next best were 2005S and 2007SK, which are soft but slightly weak and not ideal. In addition, 2007SK has the same composition as 2007S, but due to the difference in the factory, although it is the same on the data, it feels the roughness of the eyes, and it feels a little caught when washed. The result was that 20M was hard, 20S was soft and had no waist, and 20SS was too soft and had no waist when wet, making it difficult to use.

FIG. 4 is a basic configuration explanatory view showing a dedicated device for processing a slit of a cleaning sponge according to the present invention. 4 (a) is a plan view, FIG. 4 (b) is a front view, and FIG. 4 (c) is a side view.

The slit-filled cleaning sponge manufacturing apparatus 2 is a dedicated device for forming the slits of the slit-filled cleaning sponge 1 according to the present invention, and as shown in FIG. 4, the base 100, the rotary blade 110, and the motor 120. A slide guide 130, a slide bed 140, a pressing mechanism 150, and a control unit 160 will be described below.

The base 100 is a main body for arranging each of the constituent members described later, and is composed of a rigidly configured frame structure, a plate-shaped member, or the like.

The rotary blade 110 is also generally called a round cutter, and is a disk-shaped rotary blade that is arranged and fixed to a plurality of rotary blades. In the embodiment, 21 blades having a diameter of 45 mm and a thickness of 0.3 mm are arranged on the rotary shaft. Was used. Although it depends on the rotation speed, when the thickness of the rotary blade 110 is increased, a clean cut is not made, and a blade of 0.3 mm is suitable. Further, in the rotary blade 110 fixed to the rotary shaft, a spacer 116 of about 10 mm is inserted between adjacent rotary blades 110, and the size of the diamond shape 40 is determined by the thickness of the spacer 116.

The rotary shaft 115 is a shaft that is rotationally driven from the output shaft from the motor via the shaft joint 122, and is a shaft that is driven by arranging a plurality of rotary blades 110. Although not shown in the drawing, it is provided with a key portion corresponding to a key groove provided in the hole portion of the rotary blade 110. Since the length of the rotary shaft 115 becomes longer, it becomes more flexible, so it is desirable to use a heat-treated carbon steel or the like. It is also possible to handle general structural rolled steel (SS material). In the examples, an SS material having a diameter of 8 mm was used, but no particular problem occurred.

The spacer 116 is a member that determines the distance between adjacent rotary blades, and determines the size and shape of a diamond shape formed on the cleaning surface of the slit cleaning sponge 1.

The motor 120 is a prime mover for driving the rotary blade 110, and in the embodiment, a stepping motor is used. However, the motor 120 is not limited to this, and may be a motor that can control the rotation speed like a servo motor. In the embodiment, since torque is required to drive by providing 21 rotary blades 110, PK566NAW manufactured by Oriental Motor is used. In the examples, the rotation speed was preferably 200 rpm (150 mm / S (seconds) at the peripheral speed (1 rotation / 0.3 seconds when the diameter of the rotary blade was 45 mm).
One rotation with 500 pulses.
One pulse is 600 microseconds.
500 pulses x 600 microseconds = 300,000 microseconds = 0.3 seconds

The bearing 121 rotatably supports the rotating shaft 115 with respect to the base 100 and is a bearing for a radial load. Specifically, a so-called bearing with a unit or the like is used.

The shaft joint 122 is a joint member, a coupling, or the like for connecting the output shaft of the motor 120 and the rotary shaft 115 to transmit rotational power. Although shown schematically in FIG. 4, depending on the type of the motor 120, the output shaft output from the geared head and the rotating shaft 115 may be connected to each other.

The slide guide 130 guides the cleaning sponge to be processed by the slide bed 140. In the slide guide 130, a slit 50 for forming a diamond shape 40 on the upper surface or the bottom surface of the cleaning sponge to be processed is cut at a predetermined angle with respect to the longitudinal direction of the slide bed 140. It is a tool. In the figure, in order to change the angle of the urethane foam that is the material, the outer shape is hexagonal, and the two sets of opposite parallel sides are polygons of the same length, and they are oriented in the sliding direction of the slide bed 140. On the other hand, it is composed of a plate-shaped member having an outer shape that replaces the indexing machine and positions it at a predetermined angle. It is also desirable to provide a rotation mechanism that rotates the mounting state so that the angle at which the slit is inserted can be freely changed.

The slide bed 140 has a stepped portion for guiding the slide guide 130 so as to slide in parallel to the rotary blade, and the two sides of the slide guide 130 abut against the stepped portion so that the slide guide 130 can be slidably moved. It is prepared to be.

The opening slot 141 is an opening hole provided in the slide bed 140. The rotary blade 110 must be projected from the opening hole in order to secure a predetermined cutting depth. Therefore, it is an opening hole for preventing the protruding rotary blade 110 from coming into contact with the slide bed 140. The opening slot 141 needs to be provided for the number of rotary blades, and if it is larger than the size of the rotary blade, urethane foam can be easily drawn in. Therefore, the rotary blade 110 and the opening slot 141 are used as much as possible. It is desirable to make the gap small.

As shown by the two-dot chain line in FIG. 4, the pressing mechanism 150 is a mechanism or a configuration for pressing the urethane foam as a material from above when the slit is inserted by the rotary blade. Specifically, it is a mechanism or the like that applies pressure by an appropriate heavy object or applies uniform surface pressure by an elastic member. Since the load due to such pressing is affected by the elasticity and elongation characteristics of the urethane foam of the material to be worked, it is necessary to pressurize according to the material. In particular, if the material is soft, the problem that the rotary blade pulls the material when cutting the urethane foam tends to occur, and if it is too hard, the rotary blade wears out quickly, so it is necessary to apply appropriate surface pressure as appropriate. ..

The control unit 160 is a control unit for controlling the rotation speed of the motor 120 that drives the rotary blade 110. , It is necessary to adjust the rotation speed in the situation where it cannot be absorbed by the measures such as the surface pressure. Therefore, the stepping motor was selected in terms of the ease of changing the rotation speed, and Arduino was selected as the control board in the control unit 160 in terms of the ease of control of the stepping motor, the degree of freedom, and the cost of the control configuration. .. Arduino is a kind of one-board microcomputer, equipped with an I / O port, and can be used as an interactive device. It is a stand-alone type, that is, Arduino alone, once it is set and started to operate, it can be operated without any other computer, and as mentioned above, it is possible to have an inexpensive and simple configuration.

The slitted cleaning sponge according to the present invention is suitable not only for washing automobiles but also for cleaning high-class tableware and bathtubs that do not want to be damaged, and can be used in various fields for industrial use. The possibility is high.
