Description

  TECHNICAL FIELD The present invention relates to a method for manufacturing an endless belt-shaped member and a belt-shaped member with a hook-and-loop fastener, and in particular, a method and a surface for manufacturing an endless belt-shaped member such as a filter cloth used for a belt filter or the like and a conveyor belt for handling a relatively lightweight package The present invention relates to a belt-like member with a fastener.

  For example, as shown in FIG. 5, the belt filter used for solid-liquid separation of slurry and the like is connected to vacuum sources 25A and 25B, and vacuum trays 24A and 24B formed in a box shape having an upper opening, and a vacuum tray The grid 23 provided above 24A, 24B, the endless filter cloth 22 etc. which run above the grid 23, etc. are provided. The endless filter cloth 22 is supported by a plurality of rollers 28 (28A to 28C, etc.) and rotates in the direction of the arrow. Above the endless filter cloth 22, a supply tray 30 for supplying slurry and the like, and a cleaning water tray 31 for supplying liquid for cleaning the slurry are arranged. Moreover, in order to wash | clean the endless filter cloth 22 in parts other than the filtration part of the endless filter cloth 22, the filter cloth washing | cleaning nozzle 32 which injects high pressure water etc. is arrange | positioned (for example, refer patent document 1).

  Then, the slurry is supplied from the supply tray 30 onto the endless filter cloth 22 with the vacuum levels of the vacuum trays 24A, 24B being increased by the vacuum sources 25A, 25B, and from the washing water tray 31 on the endless filter cloth 22. The slurry is vacuum filtered while washing with the supplied liquid. The attached cake that has been incompletely peeled off from the endless filter cloth 22 is removed by the filter cloth cleaning nozzle 32.

  If the operation of the belt filter 21 having the above configuration is continued, the endless filter cloth 22 is gradually consumed, and the endless filter cloth 22 is clogged, and eventually the stable operation cannot be continued. 22 needs to be replaced periodically. When a new endless filter cloth is attached to the apparatus after the endless filter cloth 22 is removed, it is necessary to remove the return roller 28A, the tension roller 28C, and the like, and therefore it takes a long time to replace the endless filter cloth 22. Was.

  In addition, after the belt-shaped filter cloth is carried into the apparatus, the endless filter cloth 22 is newly formed by sewing the both ends with sutures, and is not proposed. However, for example, it takes a long time for the suturing operation, and the operation of the belt filter 21 needs to be stopped during that time.

  Furthermore, in this method, since the suturing operation is a manual operation, the filter cloth is damaged or frayed due to the joining or non-bonding, and the life of the filter cloth is affected. Also, when sewing the filter cloth, it was treated so that the filter cloth was not frayed with an epoxy resin or the like, but since the resin part is not breathable and liquid-permeable, the slurry cannot be filtered at this part. . For this reason, when the slurry reaches the return roller 28A while adhering to the endless filter cloth 22 in a high moisture state, there are problems such as contamination of the vicinity of the return roller 28A and blocking of the cleaning device 33.

  Therefore, in order to solve the above problem, as shown in FIG. 6, the filter cloth 40 is also joined by a fastener 42 having a runner 41. When this fastener 42 is used, after carrying the filter cloth 40 into an apparatus such as a belt filter, the attachment of the endless filter cloth to the apparatus is completed simply by joining both ends of the filter cloth 40 via the fastener 42. The filter cloth can be changed in a short time.

  However, when the runner-attached fastener 42 shown in FIG. 6 is used, since the fastener 42 is thick and hard, the filter cloth 40 slips at a portion such as a carrier roller and a return roller for rotating the filter cloth 40, and the apparatus is stably provided. There was a risk that the operation could not be continued. Further, the scraper cannot be brought close to the filter cloth 40, and there is a possibility that the entire filter cloth 40 may be scraped off insufficiently. Furthermore, since the fastener 42 cannot be finely adjusted in the length direction of the filter cloth 40, it is difficult to prevent the filter cloth 40 from meandering. In addition to these, after the fastener 42 is closed, it is necessary to remove the runner 41 and prevent it from being separated with a metal fitting such as a stapler. Moreover, when filtering salt water, it was necessary to use a high-grade nickel alloy or the like.
