Description

  The present invention relates to a strip rubber attaching method for attaching a strip rubber to both side edges of a belt-like corded rubber member and a strip rubber attaching device used for the strip rubber attaching method.

  A band-like corded rubber member such as a breaker is manufactured by cutting a material into a predetermined size using a cutter. At this time, since a certain tension is applied to the material, the rubber shrinks after the cutting, and the cord such as the steel cord protrudes from the rubber at the cut portion. Depending on the size of the tire, it is necessary to cure the protruding cord. In this case, a tape-shaped strip rubber called an edge strip is applied to both side edges which are cut portions (for example, patents). References 1 and 2).

  The strip rubber is lined with a release sheet called a polyliner on an unvulcanized rubber sheet, cut into a predetermined width, and wound around a roll. Normally, a pressing roller is used as an affixing method. The strip rubber is unwound from the roll while the corded rubber member is conveyed, and the rolled strip rubber is overlapped on each side edge portion of the corded rubber member. Affixed by pressing with pressure roller from above the liner. Thereafter, the polyliner is peeled off from the strip rubber and collected by a polyliner collection line.

  As the pressing roller, usually, a roller made of urethane rubber (foam rubber) that is highly elastic and can be pressed evenly even when there is unevenness or the thickness varies is used.

Japanese Patent No. 2017-148995 WO2007 / 094053

  However, in the sticking method of pressing with a pressing roller made of urethane rubber, it is not possible to ensure sufficient adhesion between the strip rubber and the corded rubber member. There is a case where the strip rubber itself is peeled off from the corded rubber member in the polyliner recovery line for peeling off the polyliner and is recovered together with the polyliner. In this case, the recovered strip rubber becomes scrap, and further, it takes time to deal with the trouble, resulting in a problem that the production efficiency is lowered.

  Accordingly, the present invention provides a strip rubber affixing technique in which the strip rubber affixed to both side edge portions of the corded rubber member is sufficiently brought into close contact with the corded rubber member without being peeled off in a subsequent process, thereby causing no reduction in production efficiency. It is an issue to provide.

[2] Embodiments of the Present Invention Based on the embodiments, the present invention will be specifically described below with reference to the drawings. In the following, a strip rubber lined with a polyliner will be described as an example of the strip rubber.

1. Strip Rubber Affixing Device According to this Embodiment First, a strip rubber affixing device according to this embodiment will be described.

  FIG. 1 is a schematic side view showing a main part of a strip rubber sticking device according to the present embodiment. In FIG. 1, 1 is a strip rubber sticking device, 11 is a rubber member conveying device, 12 is a strip rubber supply roll, 12a is a guide roller, 13 is an uneven roller, and 14 is a smooth roller. Yes, 15 is an uneven roller pressing force adjusting mechanism, and 16 is a polyliner recovery roll. B is a corded rubber member, SG is a strip rubber, PL is a polyliner, and SGB is a rubber member with strip rubber. The right side of the figure is the upstream side in the conveyance direction of the rubber member, and the left side is the downstream side.

  The strip rubber sticking device according to the present embodiment includes a sticking means for guiding and sticking the strip rubber SG to both side edges of the corded rubber member B, and a cord containing the strip rubber SG pressed by a roller. Pressure bonding means for pressure bonding to the rubber member B.

(1) Affixing means As described above, the affixing means guides and affixes the strip rubber SG to both side edges of the corded rubber member B.

  Specifically, two strip rubber SGs that are cut into a predetermined size with the polyliner PL lined on the upper surface and wound on a roll are spaced at intervals corresponding to the width of the corded rubber member B. While being set and unwound on each of the two strip rubber supply rolls 12 placed and placed, the rubber member B with cord is supplied to the rubber member transport device 11 in parallel. The rubber member transport device 11 includes a plurality of drive rollers, and transports the corded rubber member B toward the downstream side.

  The two unrolled strip rubber SGs are respectively corded by the guide roller 12a with the polyliner on the upper side and the strip rubber SG on the lower side on the conveying roller 11a arranged on the downstream side of the guide roller 12a. It is configured to be guided to both side edges of the corded rubber member B at a speed equal to the conveying speed of the rubber member B.

  FIG. 2 is a schematic perspective view of the main part of the sticking apparatus of FIG. 1 as viewed from the upstream side of the uneven roller. As described above, the strip rubber SG is supplied to both side edges via the guide roller 12a. The guide roller 12a is provided with a groove having a width substantially equal to the width of the strip rubber SG. By passing through the groove, the strip rubber SG can be guided to both side edges of the corded rubber member with high positional accuracy. . The guided strip rubber adheres to and adheres to the corded rubber member B along the surface of the corded rubber member B that has been separately conveyed.

(2) Crimping means As described above, the crimping means presses the strip rubber SG affixed to the corded rubber member B with a roller to crimp the cord rubber member B. In the present embodiment, the pressure-bonding means includes an uneven roller 13 having an uneven surface, and a smooth roller 14 having a smooth surface.

(A) Concavity and convexity roller The concavity and convexity roller 13 is arranged in the vicinity of the downstream side of the sticking means, and the strip rubber SG enters the cord by pressing the strip rubber SG stuck to the corded rubber member B by the sticking means. Crimped to rubber member B.

  The uneven roller 13 is preferably made of metal from the viewpoint of sufficiently pressing the strip rubber SG against the corded rubber member B, and particularly preferably made of alloy tool steel such as SKS31.

  FIG. 3 is a schematic front view for explaining a pressing state by the uneven roller 13, and an uneven shape is provided in the hatched portion. As shown in FIG. 3, each of the uneven rollers 13 is rotatably supported by an uneven roller support member 17, and an uneven roller pressing force adjusting mechanism 15 is connected to each uneven roller support member 17. Accordingly, the strip rubber SG can be pressed by applying a predetermined pressing force to each of the uneven rollers 13 via the uneven roller support member 17.

  As the specific uneven roller pressing force adjusting mechanism 15, a known mechanism such as a fluid pressure such as air pressure or hydraulic pressure is used.

  The width W of the concavo-convex roller 13 is 15 to 20 mm, which is slightly narrower than the width of the strip rubber SG, considering that a general strip rubber SG has a thickness of 0.5 to 0.6 mm and a width of about 25 mm. It is preferable. By setting such a width, the strip rubber SG can be pressed under a large pressing force, and the strip rubber SG can be strongly adhered to the rubber member B with cord. If it is less than 15 mm, the width to be crimped becomes too narrow. Conversely, if it exceeds 20 mm, the pressing force is dispersed, and the adhesion between the strip rubber SG and the corded rubber member B becomes weak.

  The diameter of the uneven roller 13 is preferably 30 to 50 mmφ.

  And although the uneven | corrugated process in the surface of the uneven | corrugated roller 13 is not specifically limited, A knurling process is employ | adopted preferably. And as a kind of knurling, any kind, such as a cross stitch, a flat eye, and a slant, can be used. As a specific knurling process, a knurling process of 26th (pitch: 1.00 mm, module: 0.32) to 60th (pitch: 0.42 mm, module: 0.135) is preferable.

  As a result, the corded rubber member B can be appropriately pressed and brought into close contact with the strip rubber SG. If it is less than 26th, the pressing area becomes small, the adhesion force becomes partially too large, and it may be difficult to peel off the polyliner PL in the polyliner recovery line. On the other hand, when the number exceeds 60, the surface of the uneven roller 13 is almost smooth, so a large pressing force cannot be obtained, and the strip rubber SG and the corded rubber member B cannot be sufficiently adhered, The strip rubber SG may be peeled off from the corded rubber member B.

(B) Smoothing roller The smoothing roller 14 has a length that covers the entire width of the rubber member B with the cord, and is disposed in the vicinity of the downstream side of the uneven roller 13, and further presses the strip rubber SG to enter the cord. Crimp to rubber member B. By further pressing using such a smooth roller 14, a portion that could not be pressed properly only by the uneven roller 13 is also pressed appropriately, and the strip rubber SG is more sufficiently crimped to the corded rubber member B. be able to.

  The specific smooth roller 14 is preferably made of a flexible material, and particularly preferably made of urethane rubber. Although the pressing force by the smooth roller 14 may be constant, the pressing force may be made variable according to the width of the strip rubber SG by providing a pressing force adjusting mechanism in the same manner as the uneven roller.

2. Next, the strip rubber sticking method according to the present embodiment will be described. The strip rubber sticking method according to the present embodiment includes a sticking step for guiding and sticking the strip rubber SG to both side edges of the corded rubber member B, and a cord by pressing the pasted strip rubber SG with a roller. A pressure bonding step for pressure bonding to the rubber member B.

(1) Pasting Step This step is a step of guiding and pasting the strip rubber SG to both side edges of the corded rubber member B while transporting the corded rubber member B in the longitudinal direction by the rubber member transporting device 11.

  In this step, first, two strip rubber SGs cut into a predetermined size with the polyliner PL lined on the upper surface and wound on a roll were matched with the width of the rubber member B with cord. It is set and unwound on each of the two strip rubber supply rolls 12 arranged at intervals.

  Then, the rubber member B with cord is supplied to the rubber member conveying device 11 in parallel with the unwinding of the strip rubber SG. The rubber member transport device 11 includes a plurality of drive rollers, and transports the corded rubber member B toward the downstream side. Each of the two strip rubber SGs unwound on the upstream conveying roller 11a, with the polyliner on the upper side and the strip rubber SG on the lower side, at a speed equal to the conveying speed of the corded rubber member B. Guide to both side edges.

  Thereby, as shown in FIG. 2, the strip rubber SG can be supplied to both side edges via the guide roller 12a. As described above, the guide roller 12a is provided with a groove having a width substantially equal to the width of the strip rubber SG. By passing through the groove, the strip rubber SG is guided to both side edges of the corded rubber member with high positional accuracy. can do. The induced strip rubber adheres to and adheres to the surface of the corded rubber member B.

  In the present embodiment, the strip rubber to be attached has a polyliner on the upper surface as described above, and when this polyliner is on the upper surface, in the pressing in the pressure bonding step, which is the next step, It is possible to prevent the uneven roller from sticking to the strip rubber.

(2) Crimping step This step is a step of pressing the strip rubber stuck in the sticking step onto the corded rubber member by pressing it with a roller. In the pressure-bonding step, after pressing with the uneven roller in the first pressure-bonding step, the strip rubber is sufficiently pressed and brought into close contact with the corded rubber member by pressing with the smooth roller in the second pressure-bonding step.

(A) First pressure bonding step In the first pressure bonding step, the strip rubber SG bonded in the bonding step is pressed onto the corded rubber member B by pressing it with the uneven roller 13 on the conveying roller 11a.

  At this time, the strip rubber SG can be strongly pressed against the corded rubber member B by applying a pressing force of 0.15 to 0.35 MPa to each of the two uneven rollers 13. If it is less than 0.15 MPa, the adhesion between the strip rubber SG and the corded rubber member B is weak, and conversely, if it exceeds 0.35 MPa, the adhesion between the strip rubber SG and the polyliner PL is strong and it is difficult to peel off the polyliner PL. .

(B) Second press-bonding step In the second press-bonding step, after pressing by the uneven roller in the first press-bonding step, pressing was performed by the uneven roller 13 using the smooth roller 14 installed on the transport roller 11a. The strip rubber SG is further pressed and pressure-bonded to the corded rubber member, and further sufficiently adhered.

  As described above, the smooth roller 14 has a length that covers the entire width of the corded rubber member B, and the corded rubber member B to which the strip rubber SG is attached is applied to the transport roller 11a with a predetermined pressure. Press.

  As a result, the portion of the strip rubber SG that does not hit the convex portion of the concave-convex roller 13 and does not sufficiently adhere to the corded rubber member B and the width W of the concave-convex roller 13 as shown in FIG. The portions not pressed by the uneven roller 13 because they are smaller are pressed, and the strip rubber SG and the corded rubber member B are pressure-bonded at these portions. As a result, when the strip rubber has a polyliner, it is possible to prevent the strip rubber from being peeled off and collected together with the corded rubber member at the time of collecting the polyliner, thereby preventing a decrease in production efficiency.

(3) Polyliner recovery step The strip rubber attaching method of the present embodiment preferably includes a polyliner recovery step when the attached strip rubber has a polyliner on the upper surface. In the polyliner recovery step, after pressing using the smooth roller 14 in the second press-bonding step, the polyliner PL is peeled from the strip rubber SG on the downstream side of the smooth roller 14, and the rubber member SGB with strip rubber is conveyed. On the other hand, the polyliner PL is wound up and collected by the polyliner collection roll 16. At this time, since the strip rubber SG attached by the strip rubber attaching method of the present embodiment is sufficiently adhered to the corded rubber member B, it is not collected together with the polyliner PL.

[3] Effects of the present embodiment In the present embodiment, first, the uneven roller 13 is pressed and pressure-bonded to the corded rubber member. However, the uneven roller has an uneven surface and has a pressing force. Therefore, the strip rubber SG can be strongly adhered to the corded rubber member B by pressing at the convex portion.

  On the other hand, since the uneven roller 13 has a narrow width and a small pressing force in a portion other than the convex portion, a portion of the strip rubber SG that is not sufficiently pressed and is not in close contact is generated, and the strip rubber SG starts from this portion. The rubber member B with cord may be peeled off. Therefore, after pressing with the uneven roller 13, the strip rubber SG is further pressed to the corded rubber member with the wider smooth roller 14, but by pressing with the wider smooth roller 14 in this way, Since a portion other than the convex portion can be efficiently pressed and brought into close contact with a larger pressing force, the starting point of peeling can be eliminated.

  Hereinafter, the present invention will be described more specifically based on specific examples.

1. Production of breaker with strip rubber In the following examples, a breaker used for manufacturing a tire is used as a corded rubber member, and strip rubber is applied to both side edges of the conveyed breaker and pressed by a roller. Was pressed to produce a breaker with strip rubber.
(1) Example A breaker with a strip rubber was produced by the following method.
Manufacturing object: Breaker with strip rubber for PC and ST tires Strip rubber: Thickness 0.6mm, width 25mm
Concavity and convexity roller: Alloy tool steel SKS31
Width 20mm, diameter 35mm
26th (pitch: 1.00 mm, module 0.32)
Smooth processing: Roller made of urethane rubber Pressing force: Uneven roller: 0.25 MPa
: Smooth roller: 0.25 MPa

(2) Comparative Example 1
A breaker with a strip rubber was manufactured in the same manner as in the example except that the uneven roller was not used and only the conventional smooth roller was used for pressure bonding.

(3) Comparative Example 2
A breaker with a strip rubber was manufactured in the same manner as in Example except that a metal roller having a smooth surface not subjected to knurling was used instead of the uneven roller.

(4) Comparative Example 3
A breaker with a strip rubber was produced in the same manner as in the example except that the smooth roller was not used and the pressing was performed only with the uneven roller.

2. Evaluation method A breaker with a strip rubber was produced for each of the Examples and Comparative Examples 1 to 3 for one month, and the strip rubber generated in the polyliner collection line during this period was closely adhered to the polyliner and collected together with the polyliner. The number of times of peeling from the breaker and the time loss (processing loss) and material loss (scrap loss) that occurred due to the treatment corresponding to the peeling of the strip rubber were determined.

3. Evaluation results Table 1 summarizes the results of Examples and Comparative Examples 1 to 3.

  From Table 1, it was found that no strip rubber peeling occurred in the examples, and no processing loss and scrap loss occurred. This is considered to be because the strip rubber is pressed against the breaker by the pressing by the uneven roller and the smooth roller, and is sufficiently adhered.

  On the other hand, in Comparative Example 2 using a metal roller having a smooth surface that is not knurled as an uneven roller, and in Comparative Example 3 in which pressing is performed only with an uneven roller without using a smooth roller, only a conventional smooth roller is used. Although the number of occurrences of strip rubber peeling, processing loss, and scrap loss were reduced as compared with Comparative Example 1 in which pressing was performed, it was found that the effect was limited. This is presumably because the strip rubber is not sufficiently adhered to the breaker.

  While the present invention has been described based on the embodiments, the present invention is not limited to the above embodiments. Various modifications can be made to the above-described embodiments within the same and equivalent scope as the present invention.
