Abstract

<P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for formation of a strip component capable of preventing adhesion between the components reliably without use of an adhesion preventive sheet. <P>SOLUTION: Both surfaces of a strip component BM3 in the thickness direction are processed to be rough and adhered with an adhesion preventive agent PW. The adhesion preventive agent remains in two or more concave parts P1 formed by the rough surface processing, and parts other than convex parts P2 in the rough-surface-processed surface becomes harder to touch the outside matter to. When the strip components BM3 come in contact with each other, therefore, the adhesion preventive agent PW remaining in the individual concave parts P1 between the strip components BM3 are arranged reliably for the prevention of adhesion, and the area of direct contact between the strip components BM3 becomes smaller. The processing method thus enables reliable prevention of mutual adhesion of strip components BM3 without use of an adhesion preventive sheet and is very advantageous in an attempt of improving the production efficiency. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a method and an apparatus for forming a belt-shaped member for molding a belt-shaped member made of an unvulcanized rubber material used for manufacturing a long member such as a hose or an electric wire or a pneumatic tire for an automobile. .

  In general, as a method for forming this type of band-shaped member, a band-shaped member made of an unvulcanized rubber material is continuously formed, and the continuously-formed band-shaped member is wound on a winding shaft together with a band-shaped anti-adhesive sheet. Is known to be stored or used while being wound around a winding shaft (see, for example, Patent Document 1).

In addition, as another method for forming the band-shaped member, a band-shaped member made of an unvulcanized rubber material is continuously formed, and a powdery anti-sticking agent is attached to the continuously-formed band-shaped member, and the anti-sticking agent is attached. It is known that a belt-like member is accommodated in a folded manner in a top-opening container, and the belt-like member is stored or used in a state of being folded in a top-opening container.
JP-A-5-84850

  By the way, in each said molding method, since the strip | belt-shaped member which consists of an unvulcanized rubber material is easy to mutually adhere | attach, when adhesion | attachment arises, it cannot take out a strip | belt-shaped member easily. The adhesion between the band-shaped members is prevented.

  Here, in the former forming method of the band-shaped member, in order to prevent the band-shaped members from sticking to each other, the band-shaped member is wound around the winding shaft together with the band-shaped anti-sticking sheet. However, there is a problem in that it takes time to wind and take out the belt-like member. In addition, when the belt-shaped member is wound on the winding shaft together with the anti-adhesion sheet, the length of the belt-shaped member to be wound is limited because the winding-up of the belt-shaped member tends to occur when the length of the belt-shaped member to be wound becomes long. There was also a problem.

  Moreover, in the latter method for forming the band-shaped member, since the anti-adhesion sheet is not used to prevent the adhesion between the band-shaped members, it is possible to save time and labor by using the anti-adhesion sheet. However, as shown in FIG. 5, when the band-like members BM to which the anti-adhesive agent PW is attached are stacked and stored, the anti-blocking agent PW is buried in the band-like member BM, and the band-like members BM may stick to each other. Therefore, there is a problem that it takes time to take out the belt-like member BM.

  The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a method for forming a belt-like member and an apparatus thereof that can reliably prevent sticking between the belt-like members without using an anti-adhesion sheet. There is to do.

  In order to achieve the above object, the present invention continuously forms a band-shaped member made of an unvulcanized rubber material and attaches the anti-blocking agent to the molded band-shaped member, thereby providing a band-shaped member with an anti-blocking agent. In the method for forming a belt-shaped member, the both surfaces in the thickness direction of the belt-shaped member are processed into a rough surface before attaching the anti-adhesive agent.

  The present invention also comprises a molding means for continuously molding a band-shaped member made of an unvulcanized rubber material, and an anti-adhesion treatment means for adhering an anti-blocking agent to the molded band-shaped member. The belt-shaped member molding apparatus for molding the belt-shaped member includes rough surface processing means for processing both surfaces in the thickness direction of the belt-shaped member into a rough surface before the adhesion preventing agent is attached.

  Thereby, after processing both surfaces of the strip-shaped member in the thickness direction into a rough surface, the anti-adhesive agent is attached to the strip-shaped member, so that the plurality of concave portions formed by processing into the rough surface are formed. As the anti-sticking agent accumulates, it becomes difficult for the portions other than the convex portion to come into contact with the outside on the surface processed into a rough surface, and even if the strip members are brought into contact with each other in the thickness direction, each concave shape is formed between the strip members. While the anti-sticking agent accumulated in the portion is reliably disposed, the contact area where the belt-shaped members are in direct contact with each other is reduced.

  According to the present invention, even if the belt-shaped members are brought into contact with each other in the thickness direction, the anti-blocking agent accumulated in each concave portion can be reliably disposed between the belt-shaped members, and the belt-shaped members are in direct contact with each other. Since the contact area can be reduced, it is possible to reliably prevent the sticking between the band-like members without using an anti-sticking sheet, which is extremely advantageous for improving the production efficiency.

The cylinder 43 includes a known air cylinder or hydraulic cylinder, and can move the second roller 42 toward the first roller 41. That is, when the second roller 42 is moved to the first roller 41 side by the cylinder 43, the belt-like member BM3 wound around the first roller 41 is sandwiched between the outer peripheral surfaces of the rollers 41, 42, and the first roller 41 The outer peripheral surface of the second roller 42 is pressed against one surface in the thickness direction of the strip member BM3, and the outer peripheral surface of the second roller 42 is pressed against the other surface in the thickness direction of the strip member BM3.

  The anti-tack treatment apparatus 50 includes a container 51 for storing a well-known anti-sticking agent PW in powder form, and a drive shaft 52 provided in the container 51. The container 51 is formed so as to open on the upper surface, and accommodates the anti-blocking agent PW until the drive shaft 52 is filled. A belt-like member BM3 is wound around the drive shaft 52 from below, and the belt-like member BM3 is conveyed in the longitudinal direction. That is, the belt-like member BM3 is wound around the drive shaft 52 and conveyed in the longitudinal direction, so that the belt-like member BM3 passes through the anti-blocking agent PW, and the anti-sticking agent PW adheres to the surface of the belt-like member BM3. .

  The transport device 60 is formed of, for example, a well-known belt conveyor. The belt-shaped member BM3 that has passed through the adhesion prevention processing device 50 is placed thereon, and the belt-shaped member BM3 is transported in the longitudinal direction.

  The guide device 70 includes a guide member 71 and a moving mechanism 72 that reciprocates the guide member 71 in, for example, a transport direction (hereinafter referred to as a member transport direction) of the belt-shaped member BM3 by the transport device 60. Moreover, the guide member 71 has a pair of guide plates 71a provided so as to face each other in the member conveyance direction, and a pair of fixing plates 71b for fixing each guide plate 71a. Each guide plate 71a is formed in a flat plate shape, and is arranged so that the interval between the guide plates 71a gradually decreases from the top to the bottom. The moving mechanism 72 supports the guide member 71 and reciprocates the guide member 71 by a known mechanism such as a motor or a ball screw. Further, the guide member 71 is disposed below the front end of the transport device 70 so that the belt-like member BM3 fed from the transport device 60 passes between the guide plates 71a of the guide member 71.

  The top opening container 80 has a flat bottom plate 81 and a pair of side plates 82 extending upward from both ends of the bottom plate 81 in the member conveying direction.

  The container transport device 90 is composed of, for example, a well-known roller conveyor or belt conveyor, and is configured so that a plurality of upper surface opening containers 80 can be placed thereon. Further, any one of the upper surface open containers 80 on the container transfer device 90 is arranged below the guide member 71 of the guide device 70.

  In the belt-shaped member forming apparatus configured as described above, when the belt-shaped member BM3 to which the anti-blocking agent PW is attached is formed, first, the belt-shaped member BM3 is formed by the extruder 10, the rolling roller 20, and the cutting device 30. Continuous molding.

  Next, the continuously formed belt-like member BM3 is wound around the outer peripheral surface of the first roller 41 of the rough surface processing apparatus 40, and the second roller 42 is moved to the first roller 41 side by the cylinder 43. Thereby, the outer peripheral surface of the first roller 41 is pressed against one surface in the thickness direction of the strip member BM3, and the outer peripheral surface of the second roller 42 is pressed against the other surface in the thickness direction of the strip member BM3. In this state, the first roller 41 conveys the belt-like member BM3 in the longitudinal direction, so that fine irregularities on the outer peripheral surfaces of the rollers 41 and 42 are continuously transferred to both surfaces in the thickness direction of the belt-like member BM3. The That is, both surfaces in the thickness direction of the strip member BM3 are continuously processed into a rough surface.

  Subsequently, the anti-blocking agent PW is continuously adhered to the band-shaped member BM3 that has passed through the rough surface processing apparatus 40 by the anti-sticking processing apparatus 50. Here, since both surfaces in the thickness direction of the strip-shaped member BM3 are processed into a rough surface, the anti-blocking agent PW is formed on the plurality of concave portions P1 formed on both surfaces in the thickness direction of the strip-shaped member BM3. Accumulate (see FIG. 3).

  Subsequently, the belt-like member BM3 that has passed through the adhesion preventing treatment device 50 is continuously conveyed by the conveyance device 60, and the belt-like member BM3 continuously sent out from the conveyance device 60 is guided in each guide member 71 of the guide device 70. Pass between the plates 71a. Here, since the upper surface opening container 80 is disposed below the guide member 71 of the guide device 70, the belt-like member BM3 that has passed between the guide plates 71a is accommodated in the upper surface opening container 80.

  In this state, the guide member 71 is reciprocated by the moving mechanism 72. That is, since the guide member 71 reciprocates in the member transport direction with the strip member BM3 continuously passing between the guide plates 71a of the guide member 71, the strip member BM3 is placed in the upper surface opening container 80. It is accommodated in a zigzag shape (see FIG. 1).

  Here, when the band-shaped member BM3 is accommodated in a folded manner in the upper surface opening container 80, the band-shaped members BM overlap each other in the thickness direction, but are formed on both surfaces in the thickness direction of the band-shaped member BM3. Since the anti-adhesive agent PW is accumulated in the plurality of concave portions P1 and the portions other than the convex portion P2 are difficult to come into contact with the outside on both surfaces in the thickness direction of the strip member BM3, between the strip members BM3 While the anti-sticking agent PW collected in each concave portion P1 is reliably arranged, the contact area where the strip-like members BM3 are in direct contact with each other is reduced.

  As described above, according to the present embodiment, since both surfaces in the thickness direction of the strip-shaped member BM3 are processed into a rough surface, the anti-blocking agent is attached to the strip-shaped member BM3. As a result, the anti-blocking agent PW accumulates in the plurality of concave portions P1 formed as a result, and portions other than the convex portions P2 are less likely to come into contact with the outside on the roughened surface, so that the strip members BM3 are thickened. Even if it is made to contact in the direction, the anti-blocking agent PW collected in each concave portion P1 is reliably disposed between the strip-shaped members BM3, and the area in which the strip-shaped members BM3 are in direct contact with each other is reduced. That is, it is possible to reliably prevent the band members BM3 from sticking to each other without using an anti-sticking sheet, which is extremely advantageous for improving the production efficiency.

  Further, by pressing the rollers 41 and 42 whose outer peripheral surfaces are formed on a rough surface against both surfaces in the thickness direction of the strip member BM3, both surfaces in the thickness direction of the strip member BM3 are roughened. Since it was processed, both surfaces in the thickness direction of the belt-like member BM3 can be processed continuously and reliably into a rough surface, which is extremely advantageous for improving the production efficiency.

  In the present embodiment, a rough surface processing device 40 that presses the rollers 41 and 42 from both sides in the thickness direction is provided on the belt-shaped member BM3, and the rough surface processing device 40 uses both the thickness direction of the belt-shaped member BM3. The surface is processed into a rough surface. On the other hand, as shown in FIG. 4, a rough surface processing apparatus 100 is provided instead of the rough surface processing apparatus 40, and both surfaces in the thickness direction of the strip member BM 3 are roughened by the rough surface processing apparatus 100. It is also possible to process it.

  In this case, the rough surface processing apparatus 100 includes a roller 101 around which the belt-like member BM3 is wound, and an endless member that rotates in synchronization with the roller 101 while pressing the belt-like member BM3 wound around the roller 101 against the roller 101. 102. The outer peripheral surface of the roller 101 is formed into a rough surface by a known knurling process. That is, innumerable fine irregularities are formed on the outer peripheral surface of the roller 101. The endless member 102 is rotatably supported from the inside by a plurality of support rollers 102a and a roller 103a of a tension setting mechanism 103. When tension is applied to the endless member 102, a belt-like member BM3 wound around the roller 101 is used. Is pressed against the roller 101 by the endless member 102. The roller 101 is driven to rotate, and each roller 102 a and roller 103 a are rotated by the rotational force of the roller 101. The endless member 102 is made of a metal material or a fiber material, and is formed in a net shape or a cloth shape. That is, the outer peripheral surface of the endless member 102 is a rough surface in which countless fine irregularities are formed. Further, the tension setting mechanism 103 includes a known tensioner or the like that can arbitrarily set the tension of the endless member 102. By changing the tension of the endless member 102 by the tension setting mechanism 103, the endless member 102 causes the band-shaped member to be changed. The pressing force for pressing the BM 3 against the roller 101 can be adjusted.

  For this reason, the rough surface processing apparatus 100 can continuously and surely process both surfaces in the thickness direction of the belt-like member BM3 into a rough surface, which is extremely advantageous in improving the production efficiency. Further, compared to the case where the surface of the belt-like member BM3 is processed into a rough surface by the rollers 41 and 42, the time during which the roller 101 and the endless member 102 are pressed against the belt-like member BM3 can be lengthened. This is advantageous in processing the belt-like member BM3 made of an unvulcanized rubber material that is difficult to deform into a rough surface.

  In the present embodiment, the band-shaped member BM3 to which the anti-blocking agent PW is attached is shown in a zigzag manner in the upper surface opening container 80 whose upper surface is opened, but the band-shaped member to which the anti-blocking agent PW is attached. The member BM3 can be wound around the winding shaft, and the belt-like member BM3 can be stored by other methods.
