Description

  The present invention relates to a plate cleaning belt used in an apparatus for cleaning a metal plate with a cleaning liquid while being conveyed by the belt.

  Metal plates are used in various applications such as electrical equipment and machine tools. Such metal plates are likely to have oil or dust on the surface, and many of them are undesirable if the surface of the plate is dirty, and often the plate is washed.

  Dedicated devices for cleaning metal plates have been developed and are automatically cleaned using such devices. For example, as shown in Patent Document 1, a metal plate is inserted from a hopper and separated so that the sheets do not overlap each other, and are transported on a belt. Then, the cleaning solution is removed and dried to complete the cleaning. Such an apparatus is excellent in that cleaning can be performed continuously and processing capacity can be increased.

  Further, although not intended for plate cleaning, a technique for making a hole in a belt in a conveying belt is already known as shown in Patent Document 2.

  However, since the cleaning liquid is applied while being conveyed by the belt, the cleaning liquid may accumulate on the belt or the cleaning liquid may flow at a certain position on the belt, and the friction between the belt and the metal plate may occur. Since the coefficient is lowered, there is a problem that the plate carrying capacity is lowered, the number of washings per unit time as a washing device is reduced, or the belt cannot carry the plate at all in some cases.

  Therefore, the present invention is a belt used in a cleaning method in which cleaning liquid is sprayed while being conveyed by the belt, and the coefficient of friction between the belt and the plate is caused by the cleaning liquid flowing on the belt or collecting on the belt. It is an object of the present invention to provide a plate cleaning belt capable of solving problems such as a decrease in conveyance capacity and a decrease in conveyance capability and the inability to carry out conveyance at all.

  In order to solve such problems, according to claim 1 of the present invention, in a plate cleaning belt for cleaning a metal plate by applying a cleaning liquid while being conveyed on the belt, the surface of the belt plate has a pattern. It has the location which has, and the flat surface part which does not provide the pattern, It is characterized by the above-mentioned.

  According to a second aspect of the present invention, the plate cleaning belt has a flat surface where no pattern is provided and is a joint portion of the belt.

  A third aspect of the present invention is a plate cleaning belt in which at least one drainage hole is provided in the belt, and a fourth aspect of the present invention is a plate cleaning belt in which the drainage hole is disposed on the flat surface portion.

  By arranging both the pattern area on the belt surface and the flat surface part where no pattern is provided, the flow of the cleaning liquid flowing on the surface of the belt is disturbed by changes in the pattern, and the flow of the cleaning liquid is made constant. By concentrating, it is possible to solve the problem that the metal plate slips, and it is possible to obtain a belt having high conveyance efficiency in the cleaning process of the metal plate.

  Further, it is advantageous in that the flat surface portion on which the pattern is not provided in the second aspect is located at the belt joining portion so that the flat surface portion can be provided simultaneously with the belt joining operation.

  By providing a drain hole in the belt, the cleaning liquid on the belt is not discharged and does not collect or flow on the belt, so that it is possible to eliminate the reduction in the coefficient of friction between the belt and the plate. .

  A metal plate cleaning apparatus using the plate cleaning belt of the present invention is, for example, as shown in FIG. 1, and includes a plate cleaning belt 1, a cleaning liquid supply device 2, a wiping roller 3 for wiping the cleaning liquid on the plate, and the like. Become.

  A metal plate 4 supplied from a plate supply port (not shown) is subjected to a cleaning liquid 6 by a cleaning liquid supply device 2 while being transported on a plate cleaning belt 1 wound around two rollers 5. 4 is washed, and when the washing is completed, the cleaning agent attached to the plate 4 is wiped off by the wiping roller 3.

  The plate 4 is cleaned on the plate cleaning belt 1 and then the cleaning solution is wiped off. However, if a plurality of plates overlap each other, the overlapped portion cannot be sufficiently wiped off. In the next process, the plate-like body 7 is arranged close to the belt, and by passing through the slit 8, the stacked plates 4 are broken and separated into individual pieces. Is provided. It is possible to use not only a plate-like body but also a roll brush for breaking the piled plates 4.

  In this way, the cleaning liquid 6 is applied to the plate, and dirt such as oil and dirt adhering to the plate is removed, and the plate 4 separated one by one is conveyed on the plate cleaning belt 1 and wiped off. It is fed into the roller 3.

  The plate sent to the wiping roller 3 is sandwiched between two rollers coated with a material that absorbs water on the surface, and the cleaning agent adhering to the plate is wiped off. The plate from which the cleaning liquid has been wiped off is stored or discharged from a plate receiver provided in the apparatus.

  The plate in the present invention is not particularly limited in type, and is made of a material such as an aluminum alloy, zinc, or copper, and various shapes such as a rectangle, an ellipse, and a circle are objects to be cleaned.

  The plate cleaning belt of the present invention is made of a material such as a thermoplastic polyurethane elastomer, a thermoplastic polyester elastomer, a thermoplastic polyamide elastomer, a soft polyvinyl chloride, a polyolefin, or a silicone rubber as shown in a cross section in FIG. A core body 9 such as polyester fiber, nylon fiber, vinylon fiber, cellulosic fiber, or aramid fiber was laminated or embedded in the surface layer 10. The flat belt has a thickness of about 0.5 to 6 mm and a width of about 30 to 2000 mm.

  The surface layer 10 constituting the surface of the belt needs to be constituted by a surface shape with a pattern 11 such as a vertical groove or a cloth, not a flat surface, in order to give a sufficient frictional force to convey the plate for cleaning. is there. This pattern is not limited to vertical grooves and textures, but can take various forms such as horizontal grooves and oblique grooves. In addition, it is preferable to use polyvinyl chloride as the material, especially soft polyvinyl chloride. By doing so, an appropriate frictional force is generated between the metal plate and the cleaning liquid is present to cause slippage. Even under easy-to-use conditions, the metal plate can be transported more reliably.

  Since the cleaning liquid is applied to the plate being transported on the surface of the belt to clean the plate, the cleaning liquid may not easily flow down from the surface of the belt, and the cleaning liquid water channel may be formed on the surface. In this case, a problem that the plate slides with the flow of the cleaning liquid and cannot be transported easily occurs. Therefore, in the present invention, as shown in FIG. 3, the cleaning liquid that has flowed along the pattern 11 in other portions by forming the flat surface portion 12 not provided with the pattern on a part of the entire surface of the belt. The flow of the air is disturbed, and some of the material flows out of the belt surface, which makes it difficult for the plate to slide.

  The ratio of the flat surface not provided with the above pattern in the entire belt circumference is preferably in the range of 5 to 50%, and if it is less than 5%, the effect of disturbing the flow of the cleaning liquid is poor. Further, the flat surface is originally a surface on which the plate is slippery, and if it exceeds 50%, it is not preferable because slippage tends to occur. Further, the flat surface portion 12 is not limited to one location in the entire belt circumference, and a plurality of locations can be provided.

  Moreover, it can be said that providing the flat surface portion 12 at the joint portion of the belt is a preferable form because the flat surface portion can be provided simultaneously with the joining process.

  Furthermore, as shown in FIG. 4, it is also possible to provide drainage holes 13 in the belt and discharge the cleaning liquid on the belt from the drainage holes 13 to the bottom of the belt to prevent slippage between the plate and the belt. The flat surface portion 12 has no pattern on the belt surface and is likely to slip with the plate. In particular, the flat surface portion 12 can be prevented from slipping by providing the drain hole 13 in the flat surface portion 12. Of course, you may provide in places other than the flat surface part 12. FIG.

  The size of the drain hole 13 is set to such a size that the plate 4 does not pass through the belt 1 and does not fall from the belt 1 so that the cleaning liquid is drained, and the hole has a diameter of about 2 to 30 mm. Is provided. If the diameter is less than 2 mm, the cleaning liquid is not sufficiently drained. If the diameter exceeds 30 mm, the plate may pass through, the belt strength may be insufficient, or the contact area between the plate and the belt may be small. It is not preferable because there is a problem of becoming.

  The shape of the drain hole 9 is described on the premise of a round shape such as the size of the hole, but is not particularly limited, and may be a triangular shape or a quadrangular shape. However, when the shape has corners, a round shape is preferable because a problem that the belt tears from the corners may occur. Even if the shape has corners, it is preferable to round the corner tips.

  Next, belts serving as examples and comparative examples of the present invention were prepared, the plates were actually cleaned, and the time required for cleaning and discharging a predetermined number of plates was compared.

Example 1
In the embodiment, a canvas made of polyester fiber is used as the core, and the surface is a belt having a width of 280 mm and a circumferential length of 730 mm coated with a polyurethane elastomer having a depth of 0.5 mm and a pitch of 2 mm, and a length of 730 mm. A belt having a joint surface of 100 mm and a flat surface without providing the longitudinal groove on the surface of the joint portion was prepared, and the plate was washed in the configuration as shown in FIG. The supply amount of the cleaning liquid was 500 cc / min, and the running speed of the belt was 6.5 m / min.

  The number of washed plates is 1500, and the used plate has a diameter of 25 mm, a thickness of 1.7 mm, and a weight of 5.3 g / sheet. The time from supplying the plate to cleaning all the 1500 plates was measured. The results are shown in Table 1.

(Comparative Example 1)
Except that the same longitudinal grooves as those of the other transport surfaces were provided on the surface at the joint, the same belt as in Example 1 was prepared, and the plate was similarly cleaned with the configuration shown in FIG. The supply amount of the cleaning liquid was 500 cc / min, and the running speed of the belt was 6.5 m / min.

  The number of washed plates is 1500, and the used plate has a diameter of 25 mm, a thickness of 1.7 mm, and a weight of 5.3 g / sheet. The time from supplying the plate to cleaning all the 1500 plates was measured. The results are shown in Table 1.

  As shown in the results of Table 1, in Example 1 in which the joint portion is not provided with a vertical groove and has a flat surface, no sliding of the plate is observed as compared with Comparative Example 1 in which the joint portion is provided with a vertical groove. The time for discharging one plate is considerably shortened to 1/3, and the flow of the cleaning liquid is disturbed by making the joint portion a flat surface, so that the effect of the present invention is manifested because the plate is less likely to slip. I understand.
