Description

  The present invention relates to a belt member manufacturing apparatus and method, and more particularly, a wide belt member having various predetermined cord angles by cutting a plurality of belt members at a predetermined angle and a predetermined length and then joining them. It is related with the manufacturing apparatus and method of a belt member which can manufacture smoothly.

  A belt member obtained by coating a large number of steel cords arranged in parallel at a predetermined cord angle with rubber is used for rubber products such as tires. This belt member is manufactured by cutting a belt material in which steel cords arranged in parallel with rubber are cut into a predetermined length at a predetermined angle set in accordance with the cord angle, and joining the cut belt materials together. Various manufacturing methods have been proposed (see, for example, Patent Document 1).

  Conventionally, when a belt material is cut into a predetermined length at a predetermined angle, for example, the belt material is sent onto a take-up conveyor by a delivery conveyor, and is cut at a position where the belt material is sent out for a predetermined length. Alternatively, the belt material is lifted by a suction pad or the like, pulled out on a take-up conveyor, and cut at a position where it has been pulled out by a predetermined length.

  However, in the case of manufacturing a wide belt member, in the former method, the distance to which the belt material is sent out becomes long, so that the belt material is bent due to friction between the belt material and the take-up conveyor during feeding, There has been a problem that it becomes impossible to feed onto the take-up conveyor stably and smoothly. This problem becomes more prominent as the width of the belt material sent out increases. In the latter method, since the distance to be lifted and pulled out becomes long, the belt material is likely to fall or slip while being pulled out, and the belt material can be stably and smoothly pulled out on the take-up conveyor. There was a problem of disappearing. In particular, this problem becomes significant when the weight of the belt material is heavy.

As described above, when the belt material is cut into a predetermined length at a predetermined angle, it is difficult to stably and smoothly place the belt material on the take-up conveyor. Therefore, wide belts having various predetermined cord angles. It was difficult to manufacture the member smoothly.

The holding unit 5 includes a holding frame 5a, rollers 5b, 5c, and 5d provided below the holding frame 5a, and receiving plates 5e and 5f. The lower roller 5b and the receiving plates 5e and 5f are belt materials. B is placed, and the upright roller 5c guides the belt material B. Further, the upper roller 5d is configured to move closer to and away from the lower roller 5b, and sandwich the belt material B between the lower roller 5b and the lower roller 5b when moved closer. The holding frame 5 a moves forward and backward along the length direction of the main body frame 4 by a drive device of the main body frame 4.

  Moreover, the delivery means 3 is installed so that the length direction of the main body frame 4 and the holding frame 5a can be directed in an arbitrary direction. That is, when the belt material B placed on the holding unit 5 is sent out, the delivery means 3 is installed so that the delivery angle b of the belt material B with respect to the length direction of the take-up conveyor 2 can be changed.

  The positioning means 6 has a contact portion 7 and a presser portion 8 that extend linearly in the length direction of the take-up conveyor 1. The presser part 8 is pivotally supported so that it can move up and down in the vicinity of the contact part 7. The positioning means 6 is installed so as to be movable in the length direction and the width direction of the take-up conveyor 2 above a predetermined interval from the surface of the take-up conveyor 2. The positioning means 6 is configured to move to a predetermined position and position according to the feeding angle b and the feeding length L of the belt material B placed on the holding unit 5.

  As illustrated in FIGS. 1 and 12, the joining means 10 includes two guide rails 11 installed above the take-up conveyor 2 and a pair of joining rollers 12 suspended downward from the guide rails 11. ing. Each of the pair of joining rollers 12 is pivotally supported on the rotation shaft so as to intersect each other so that the upper peripheral edges thereof are in contact with each other, and the peripheral edges of the joining rollers 12 rotate while being in contact with the joints of the belt material B. Then, the joining end portions of the belt material B are pressed together. The guide rail 11 can be moved to an arbitrary position in the conveyor feeding direction above the take-up conveyor 2 and can be turned in an arbitrary direction by turning the guide rail 11. . The position and orientation of the guide rail 11 are determined according to the feed angle b of the belt material B, the width of the belt material B, and the width of the belt member A.

  Hereinafter, the procedure of the manufacturing method of the belt member A by the manufacturing apparatus 1 will be described.

  First, as illustrated in FIGS. 1 and 2, the belt material B fed from the supply source is placed on the holding unit 5 of the delivery means 3. At this time, the feeding means 3 is installed so that the length direction of the main body frame 4 and the holding frame 5a is matched with the set feeding angle b (that is, the cord angle a) of the belt material B. The positioning means 6 is moved according to the feed angle b and the feed length L, and positioned so that the tip of the fed belt material B comes into contact with the contact portion 7. The presser part 8 is kept in a position above the contact part 7.

  Next, as illustrated in FIGS. 3 and 4, the belt material B to be fed is sandwiched between the roller 5 c by moving the roller 5 d downward. In this state, the holding frame 5a is advanced by a predetermined delivery length L toward the take-up conveyor 2. Since the belt material B is sandwiched between the rollers 5 b and 5 d, the belt material B is sent out on the take-up conveyor 2 by a predetermined length L while being placed on the holding unit 5. The feeding length L is calculated from the width of the belt member A and the feeding angle b of the belt material B.

  The leading end of the fed belt material B is abutted against the abutting portion 7 and positioned. At this time, the receiving plate 5e may be swung downward and the tip of the belt material B may be brought into contact. After the front end of the belt material B comes into contact with the contact portion 7, the presser portion 8 is moved downward to press the front end portion of the belt material B onto the take-up conveyor 2 by the presser portion 8.

  Next, as illustrated in FIG. 5 and FIG. 6, the holding portion 5 (holding frame 5 a) is moved backward while the leading end portion of the belt material B is pressed onto the take-up conveyor 2 by the holding portion 8. Retract from the conveyor 2. Since the leading end portion of the fed belt material B is fixed by the pressing portion 8, only the belt material B is left on the take-up conveyor 2.

  Next, as illustrated in FIGS. 7 and 8, the fixing plate 9 c is moved downward, and the fed belt material B is pressed against the flat blade 9 a and fixed. Thereafter, the round blade 9b is moved while being rotated along the flat blade 9a, and the position separated from the tip of the fed belt material B by the feed length L is sandwiched between the round blade 9b and the flat blade 9a. Cut along the length of the take-up conveyor 2.

  Next, as illustrated in FIGS. 9 and 10, the pressing portion 8 is moved upward to release the pressing of the leading end portion of the belt material B against the take-up conveyor 2. Further, the presser plate 9c is moved upward to release the pressing of the belt material B against the flat blade 9a. As a result, the belt material B having a predetermined delivery angle b and a predetermined delivery length L is placed on the take-up conveyor 2. Then, the take-up conveyor 2 is operated to convey the belt material B to the downstream side by a distance substantially the same as the width in the length direction of the take-up conveyor 2 of the placed belt material B.

  The take-up conveyor 2 is operated after the entire take-up conveyor 2 is slid to a width away from the cutting means 9 by the conveyor slide mechanism 2a. Thereby, when the take-up conveyor 2 is operated, the cut end of the belt material B becomes difficult to come into contact with the flat blade 9a, and the belt material B placed on the take-up conveyor 2 can be prevented from shifting. . The take-up conveyor 2 slid in the width direction is slid in the width direction so as to approach the cutting means 9 again after the belt material B is conveyed.

  The steps shown in FIGS. 1 to 10 described above are repeated, and the cut belt material B is sequentially placed on the take-up conveyor 2 side by side in the length direction of the take-up conveyor 2.

  When changing the delivery angle b of the belt material B to be delivered, as shown in FIG. 11, the length direction of the holding frame 5a is moved so as to match the set delivery angle b, and the delivery means 3 is moved. Is installed. Based on the newly set delivery angle b and delivery length L, the positioning means 6 and the joining means 10 are also moved to predetermined positions.

  In the present invention, the belt material B is fed out while being placed on the holding portion 5, the leading end of the fed belt material B is positioned by the contact portion 7, and the leading end portion of the belt material B is taken up by the holding portion 8. Since the holding unit 5 is retracted from the take-up conveyor 2 in a state of being fixed on the belt, it can be taken up stably and smoothly regardless of the feed length L, the feed angle b, and the weight of the belt material B. It can be sent out on the conveyor 2. Therefore, when manufacturing a wide belt member A (for example, about 600 mm to 800 mm in width), even if the feed length L of the belt material B is increased to, for example, about 1000 mm to 1400 mm, the belt member B is bent or caught. It can be reliably sent out on the take-up conveyor 2. Further, since the feed angle b can be set freely, the belt member A having various cord angles a can be handled.

  On the downstream side in the transport direction from the delivery means 3 on the take-up conveyor 2, the adjacent end portions of the belt material B placed side by side are joined by the joining means 10 on the take-up conveyor 2 with almost no gap. . The position and orientation of the guide rail 11 are set in accordance with the feeding angle b and the feeding length L of the belt material B. As illustrated in FIG. 9, the guide rail 11 has an orientation that is substantially the same as the feeding angle b. Installed.

  When the belt material B arranged in the length direction of the take-up conveyor 2 is conveyed below the guide rail 11, the pair of joining rollers 12 are adjacent to the belt material B as illustrated in FIG. Arranged so that the end portions are sandwiched, with the adjacent end portions sandwiched, along the guide rail 11 from the predetermined position between the width direction both ends of the belt member A toward the one end (next to the belt material B) Move along the length of the mating end). Next, the other pair of joining rollers 12 is moved toward the other end of the belt member A. Thereby, the ends of each other are joined.

  According to the present invention, it is possible to smoothly manufacture the wide belt member A having various predetermined cord angles as described above.

  Although it can also join using the roller which presses on the adjacent edge part of the belt material B, when a pair of joining rollers 12 like this embodiment are used, it will be gathered together. Since they can be joined, even if there are some gaps between the adjacent ends of the belt material B, the gaps can be filled and joined.
