Description

  This invention is suitable for use in forming a raw tire by forming an unvulcanized belt-shaped member mainly composed of rubber as a constituent member of a pneumatic tire by winding it on a molding drum and laminating it. The present invention relates to a member affixing device and an affixing method using the affixing device, and particularly enables high-speed adhering of an unvulcanized belt-shaped member while ensuring the required pasting accuracy of the unvulcanized belt-shaped member. Propose technology.

  For example, in the conventional technology in which an unvulcanized belt-shaped member conveyed by a belt conveyor is wound on and adhered to the circumferential surface of a rotationally driven molding drum, the conveying speed of the belt conveyor is about 1 m / s. The unvulcanized belt-like member can be adhered to the molding drum with sufficiently high accuracy, but for the purpose of improving productivity, if the conveyor speed of the belt conveyor is increased along with the drum peripheral speed, the belt conveyor and the drive are driven. Due to the difference between the actual feeding speed of the belt-like member and the rotational peripheral speed of the molding drum due to slippage between the rolls, expansion and contraction deformation of the belt conveyor, etc., the belt-like member is loosely deformed and stretched and deformed. There is a problem that such deformation of the belt-shaped member may cause a decrease in the sticking accuracy due to the meandering of the belt-shaped member on the molding drum or the like. Was Tsu.

  The problem of such a decrease in accuracy is that when using a belt conveyor that is likely to slip between the drive rolls and that is easily stretched and deformed by the acting tension, such as a resin belt conveyor. It was particularly serious.

  Further, as a prior art of “can improve the winding accuracy around the molding drum” of the unvulcanized belt-shaped member, as disclosed in Patent Document 1, “unvulcanized tire member is applied to the outer peripheral surface of the molding drum. In the tire member supplying apparatus to be supplied, a belt conveyor with a magnet for sucking and transporting the unvulcanized tire member, a belt conveyor supporting member for supporting the belt conveyor movably in the direction of the forming drum, and the belt A belt conveyor driving means for swinging the conveyor so that the front end of the belt conveyor approaches and separates from the outer peripheral surface of the forming drum, and a lower surface of the belt conveyor disposed below the rear end of the belt conveyor. And a cutting device for cutting the unvulcanized tire member adsorbed on the tire to a predetermined length. Advance the belt conveyor with magnet holding the uncut vulcanized tire member that has been cut by placing, and move the front end of the cut unvulcanized tire member to the vicinity of the winding start end position of the forming drum, Next, the belt conveyor with magnet is swung in the direction of the forming drum, the front end of the cut unvulcanized tire member is brought into contact with the winding start end position of the forming drum, and the cut unvulcanized tire member is moved to the outer periphery of the forming drum. When the forming drum rotates once and the cut unvulcanized tire member is wound around the outer peripheral surface of the forming drum, the belt conveyor with magnet is moved backward, and then the subsequent unvulcanized tire member is Adsorb to the belt conveyor with magnet, and then drive the belt conveyor with magnet to feed the front end of the subsequent unvulcanized tire member to the vicinity of the front end of the belt conveyor, and then operate the cutting device Te, cutting the same subsequent unvulcanized tire member, then it is an. "Supplied to the outer peripheral surface of the forming drum in the same manner as described above.

JP-A-63-231927

  However, in this prior art, the supply of the unvulcanized tire member to the rotationally driven forming drum is performed by the belt conveyer traveling traveling in synchronization with the peripheral speed of the forming drum. When the drum peripheral speed and the conveyor traveling speed of the belt conveyor are increased for the purpose of improvement, the same problem of lowering the sticking accuracy as described above will occur, and in this prior art, the unvulcanized tire Since the rotation of the molding drum starts from a stationary state in which the winding start end of the member is pressed against the molding drum, the inertial force is generated in the vicinity of the winding start end of the unvulcanized tire member, particularly in the initial rotation of the molding drum. There is also a problem that elongation deformation or the like due to the film tends to occur, and a reduction in sticking accuracy due to this is unavoidable.

  In addition, this prior art is a so-called top-attached type in which the peripheral surface apex position on the upper side of the peripheral surface of the molding drum is the winding start end position of the unvulcanized tire member, and is a belt conveyor with magnets Since the unvulcanized tire member adsorbed on the outer periphery of the molding drum is wound under the action of a tensile force on the unvulcanized tire member based on the rotational movement of the molding drum, There was also a structural problem that the vulcanized tire member could not be wound at such a high speed.

  An object of the present invention is to solve such problems of the prior art, and the object of the present invention is to maintain a sufficiently high adhesion accuracy of the unvulcanized belt-like member while not adding it. It is in providing the sticking apparatus of the strip | belt-shaped member which can be stuck to a shaping | molding drum at a higher speed, and the sticking method using the apparatus.

The band member pasting device of the present invention includes a conveyor belt that transports an unvulcanized belt member that is cut to a predetermined size and positioned on the transport surface, and strokes the conveyor belt itself during transport of the conveyor belt. A conveyor belt shift means capable of rotating and a molding drum which is rotationally driven and directly or indirectly affixes the unvulcanized belt-like member on the conveyor belt on the peripheral surface. When the unvulcanized belt-like member is attached to the circumferential surface of the rotationally driven molding drum, the conveyor belt is transported and the conveyor belt itself An advancing stroke is performed, and the advancing stroke of the conveyor belt itself is performed in a direction perpendicular to the central axis of the molding drum, and the conveyor belt is connected to a steel cord. Reinforced, and a rubber steel conveyor belt, a pinion rotated by the conveyor belt drive motor to advance stroke itself, provided on the base frame for horizontally supporting the conveyor belt frame disposed above the conveyor belt And a conveyor belt shift means provided with a rack laid on the lower surface of the conveyor belt frame and meshing with a pinion.

  Here, most of the molding drums are configured so that the drum circumference can be appropriately selected by expansion / contraction diameter deformation according to the required outer diameter of the circumferential surface by a link mechanism or the like. It is possible to flexibly handle the delivery of the above molded product to O-rings and others.

  Preferably, the conveyor belt is a steel conveyor belt reinforced with a steel cord and having a small amount of expansion and contraction.

  Here, the conveyor belt shift means can be constituted by a rack and pinion, a ball screw or a cylinder capable of controlling the speed and stroke amount with high accuracy.

Preferably, each of the conveyor belt and the molding drum is provided with a means for adsorbing the unvulcanized belt-shaped member by magnetism, negative pressure or the like for positioning and holding the unvulcanized belt-shaped member.
Here, when the suction means of the molding drum is a negative pressure suction means, the unvulcanized belt-like member is indirectly attached to the peripheral surface of the molding drum via another unvulcanized belt-like member. Therefore, it is extremely difficult to make the adsorption means function sufficiently without special work such as providing perforations in the unvulcanized belt-like member to be pasted.

And, the method of sticking the belt-shaped member of the present invention is the unvulcanized belt-shaped member that has been cut to a certain size and positioned on the transport surface of the conveyor belt, the conveyor belt transport travel, the advance stroke of the conveyor belt itself, The unvulcanized belt-like member is fed to a molding drum that is rotationally driven and stuck directly or indirectly on the peripheral surface, and the unvulcanized belt-like member is molded from the front end in the conveying direction. When the non-vulcanized belt-like member is attached to the peripheral surface of the drum on the peripheral surface of the drum, and the non-vulcanized belt-like member is attached to the peripheral surface of the rotationally driven molding drum, The advancing stroke of the conveyor belt itself, the advancing stroke of the conveyor belt itself is performed in a direction orthogonal to the central axis of the molding drum, and the advancing stroke of the conveyor belt itself is the molding stroke The conveyor belt is a rubber steel conveyor belt reinforced in a direction perpendicular to the center axis of the ram and reinforced with a steel cord, and the conveyor belt itself has an advancing stroke as a conveyor belt provided with the conveyor belt. The conveyor belt shift means includes a pinion that is rotationally driven by a drive motor provided on a base frame that horizontally supports the frame, and a rack that is laid on the lower surface of the conveyor belt frame and meshes with the pinion.

  Here, preferably, the tire molding drum is driven to rotate at a combined peripheral speed of the conveying speed of the conveyor belt and the advance stroke speed of the conveyor belt itself.

  Preferably, the unvulcanized belt member is positioned on the conveyor belt by adsorbing the unvulcanized belt member to the conveyor belt.

Preferably, for example, the direct sticking of the front end in the transport direction of the unvulcanized belt-shaped member onto the peripheral surface of the molding drum is started by adsorbing the front end in the transport direction to the peripheral surface of the molding drum.
By the way, in this case, when the conveyor belt has an adsorption function for the unvulcanized belt-shaped member, the molding drum side suction force is made somewhat larger than the conveyor belt-side suction force, and the unvulcanized belt-shaped member molding drum In reaching this position, the adsorption force on the conveyor belt side can be dealt with by reducing or eliminating it.

  In the band member pasting device of the present invention, in addition to the case where the unvulcanized rubber itself is used, a reinforcing cord such as a steel cord or an organic fiber cord or a woven fabric may be embedded in the unvulcanized rubber. By conveying the unvulcanized belt-shaped member of a predetermined width not only with the conveyor belt transport running, but also with the proximity stroke of the conveyor belt itself to the molding drum, the total transport speed of the unvulcanized belt-shaped member can be increased. Therefore, productivity can be sufficiently increased as the sum of the transport speed of the conveyor belt and the stroke speed of the conveyor belt itself. The conveyance speed can be considerably slowed down, and the molding drum circumference is caused by slip between the conveyor belt and the drive roll, expansion / contraction deformation of the conveyor belt, etc. Onto, a risk of decrease in the sticking accuracy of unvulcanized 硫帯 shaped member can be removed sufficiently.

  In this case, since the driving peripheral speed of the molding drum can be set to the above sum, the conveying speed of the conveyor belt is kept within a range in which the accuracy of sticking the belt-shaped member is not lowered, and the productivity is effectively improved. Can be made.

  In addition, this apparatus is a so-called under-paste type, in which the unvulcanized belt-shaped member conveyed by the conveyor belt is attached to the peripheral surface of the molding drum from the lower side of the peripheral surface of the drum. Combined with the conveyor belt transport travel and the stroke of the conveyor belt itself, the belt-like member can be wound around the drum surface at a higher speed than the top-mounted type to further improve productivity. Can be planned.

  In such an apparatus, when the conveyor belt is a rubber steel conveyor reinforced with a steel cord, the occurrence of slip between the conveyor belt and the drive roll is increased even if the conveyor belt conveyance speed is increased, And the fall of the sticking precision of a strip | belt-shaped member by the expansion-contraction deformation of a conveyor belt, etc. can be suppressed effectively.

  Here, when the conveyor belt shift means is constituted by a rack and pinion, a ball screw, a cylinder, or an electric cylinder, the amount and speed of the shift belt's shift stroke are controlled with sufficiently high precision so that the driving speed of the molding drum is increased. It is possible to easily adjust the synchronization with the speed.

And, when each of the conveyor belt and the forming drum is provided with a means for adsorbing the unvulcanized belt-like member, the conveyor of the unvulcanized belt-like member is compared with the case where it depends only on the adhesive force inherent to the belt-like member. Both the positioning and holding accuracy on the belt conveyance surface and the accuracy of application to the peripheral surface of the molding drum can be sufficiently ensured.
The adsorbing means may be a magnetic adsorbing means when the cord embedded in the belt-shaped member is a steel cord. In addition to the case where the embedding cord is a steel cord and an organic fiber cord, The negative pressure adsorbing means can be used in any case where it does not exist.

  In any of these cases, in order to smoothly and surely deliver the unvulcanized belt-shaped member from the conveyor belt to the peripheral surface of the molding drum, the suction force on the molding drum side is set to the conveyor belt side. It is preferable that the adsorption force on the conveyor belt side is reduced or eliminated when the unvulcanized belt-like member reaches the molding drum.

  And in the method of sticking the belt-shaped member of the present invention, as mentioned above, the production speed is increased by increasing the feeding speed of the unvulcanized belt-shaped member by the transport speed of the conveyor belt and the stroke speed of the conveyor belt itself. As the expected adhesion accuracy of unvulcanized belt-like members is eliminated by eliminating the risk of conveyor belt slip and expansion / contraction deformation when only the conveyor belt conveyance speed is increased. Can be.

  Moreover, in this case, the non-vulcanized belt-like member is stuck on the peripheral surface of the molding drum from the lower side of the drum peripheral surface, and is a lower-pasting-type sticking mode, thereby enabling high-speed sticking of the belt-like member. It can respond enough.

  Here, in the case where the molding drum is rotationally driven at the combined peripheral speed of the conveyor belt conveyance speed and the advancement stroke speed of the conveyor belt itself, the adhesion accuracy of the unvulcanized belt-like member is increased under the synchronization of the speed. It can be secured more sufficiently.

  When positioning the unvulcanized belt-like member on the conveyor by adsorbing the unvulcanized belt-like member to the conveyor, prevent the belt member from being unintentionally displaced on the conveyor belt. The accuracy of sticking onto the drum peripheral surface can be increased.

  In addition, when the sticking of the front end in the transport direction of the unvulcanized belt-shaped member onto the peripheral surface of the molding drum is started by adsorbing the front end in the transport direction to the peripheral surface of the molding drum, the drum of the strip-shaped member is started. The start of sticking on the peripheral surface can always be performed reliably and with high accuracy.

It is a rough-line side view which shows embodiment of the apparatus of this invention. It is a side view which shows the sticking state on the surrounding surface of a shaping | molding drum of the unvulcanized belt-shaped member by the apparatus shown in FIG. It is a side view which shows the standby state of the next operation | work of the apparatus which finished one sticking operation | work.

  In the figure, reference numeral 1 denotes a molding drum that is rotationally driven at a required peripheral speed and directly or indirectly affixes an unvulcanized belt-like member on the peripheral surface, such as a belt-tread molding drum. 1 shows a conveyor belt that conveys an unvulcanized belt-like member, and this conveyor belt 2 includes, for example, an unvulcanized rubber mainly composed of an unvulcanized rubber that is cut in a predetermined size and includes or does not include a cord. A belt-shaped member, for example, an unvulcanized belt-shaped member W having a width substantially equal to the axial length of the molding drum 1 is positioned and arranged on the transport surface by being centered or the like, and travels toward the molding drum 1 side. .

Reference numeral 3 denotes a conveyor belt frame on which the conveyor belt 2 is disposed. The conveyor belt 2 is connected to a motor 4 disposed on the conveyor belt frame 3 so that the lower side of the peripheral surface of the molding drum 1 is In the drawing, it is driven horizontally in a direction perpendicular to the central axis of the drum 1.
And here, the base frame 5 which supports such a conveyor belt frame 3 horizontally is provided, and the drive motor 6 provided in this base frame 5 is extended on the lower surface of the conveyor belt frame 3 in the length direction thereof. The rack 7 meshed with the pinion 8 and the conveyor belt frame 3 provided with the conveyor belt 2 are driven and connected to the pinion 8 meshed with the rack 7 laid over the entire length by a linear guide or the like (not shown). Under the action of the sliding guide, a horizontal posture is maintained, and translational movement is possible in both the left and right directions in the figure as required.
Accordingly, here, the pinion 8 that is rotationally driven by the drive motor 6 provided on the base frame 5 and the rack 7 that is laid on the lower surface of the conveyor belt frame 3 and meshes with the pinion 8 are independent of the conveyor belt 2 traveling. Thus, the conveyor belt shift means for stroking the conveyor belt itself is configured.
Here, instead of the rack 7 and the pinion 8, a ball screw, an electric cylinder or the like can be provided, and any of these can control the shift stroke amount and the shift speed of the conveyor belt with high accuracy. it can.

  In the apparatus configured as described above, the unvulcanized belt-like member W on the conveying surface of the conveyor belt 2 is directed to the lower side of the peripheral surface of the molding drum 1 by the conveying traveling of the conveyor belt 2, and an arrow in the figure. Conveyed horizontally as indicated by A, and in conjunction with this, the conveyor belt shift means causes the conveyor belt 2 to move along with the conveyor belt frame 3 at the required speed in the horizontal direction as indicated by arrow B in the figure. Thus, the belt-like member W can be adhered to the peripheral surface of the molding drum 1 at a sufficient speed without having to increase the conveyance travel speed of the conveyor belt 2 so much, so that productivity is effectively increased. Can do.

  On the other hand, since it is not necessary to increase the conveying speed of the conveyor belt 2 so much, the risk of a decrease in the accuracy of attaching the unvulcanized belt-like member W can be effectively removed.

  In such an apparatus, when the conveyor belt 2 is a rubber steel conveyor belt reinforced with a steel cord, a high frictional force between the conveyor belt 2 and the drive roll is obtained even though the conveying speed of the conveyor belt 2 is increased. Therefore, it is possible to effectively prevent the occurrence of slipping between them, so that the degree of freedom in selecting the conveyance speed without lowering the sticking accuracy can be increased. Moreover, the fall of the sticking precision of an unvulcanized belt-shaped member can be effectively prevented by suppressing the expansion-contraction deformation of the conveyor belt 2, etc. under the high tension | tensile_strength of a steel cord.

  In this apparatus, when each of the conveyor belt 2 and the molding drum 1 is provided with suction means for magnetic adsorption, negative pressure adsorption, etc. of the unvulcanized belt-like member W, the belt-like member W is attached to the conveyor belt 2. In addition, the positioning and holding accuracy of the unvulcanized belt-like member and the adhesion to the drum circumferential surface are compared with the case where the positioning and holding is performed on the drum circumferential surface depending only on the adhesive force inherent to the unvulcanized belt-like member W. Both accuracy can be improved.

  In this case, in order to smoothly and surely deliver the unvulcanized belt-like member W from the conveyor belt 2 to the circumferential surface of the molding drum, the suction force on the molding drum side is set to be larger than the suction force on the conveyor belt side. It is preferable to increase the size and reduce or eliminate the adsorption force on the conveyor belt side when the unvulcanized belt-like member W reaches the molding drum 1.

The implementation of the method according to the present invention by the apparatus having the structure as described above is carried out by using an unvulcanized belt-like member W, which has been cut in the previous step and positioned on the conveying surface of the conveyor belt 2, as a motor. 4, the conveyor belt 2 in the horizontal direction as indicated by the arrow A in FIG. 1, the left side in the figure, and the drive motor 6, and the conveyor belt frame 3. The unvulcanized belt-like member is directly or indirectly driven on the circumferential surface by both the horizontal movement as shown by the arrow B in FIG. The unvulcanized belt-shaped member W is fed onto the circumferential surface of the molding drum from the lower end of the drum circumferential surface by adhesion or by adsorption from the leading end in the conveying direction. By doing.
According to this, since the feeding speed of the belt-like member W to the molding drum 1 can be the sum of the conveyor belt conveyance speed and the advance stroke speed of the conveyor belt itself, the conveyor belt conveyance speed. The productivity can be increased without significantly increasing the thickness of the belt, and the risk of a decrease in the adhesion accuracy of the unvulcanized belt-like member W when only the conveying speed of the conveyor belt is greatly increased can be sufficiently eliminated.

  In addition, here, the unvulcanized belt-like member W is stuck from the lower side of the drum peripheral surface, so that the belt-like member W is placed on the lower conveyor belt as compared with the case of sticking from the upper side of the drum peripheral surface. Since it can be accurately positioned at the sticking standby position and the conveyor belt 2 can be synchronized with the sticking speed to the molding drum 1 with high accuracy, it is possible to sufficiently cope with higher speed sticking.

  By the way, when the one unvulcanized belt-like member W is stuck on the peripheral surface of the molding drum 1 as described above, the conveyor belt 2 and the conveyor belt frame 3 are Since the advancing displacement is performed as shown in FIG. 2, the base frame 5 and the conveyor belt 2 are maintained while maintaining the meshed state of the rack 7 and the pinion 8 as shown in FIG. At the same time, a reverse stroke is made to cause the conveyor belt 2 and the conveyor belt frame 3 to wait for the start of the next operation.

  Here, when the base frame 5 is made to move backward in this way, the base frame 5 itself can be horizontally stroked with respect to the floor surface 9 by a cylinder or other translation drive means 10. Although it is preferable to reduce the size of the conveyor belt frame 3, this is not essential for the apparatus according to the present invention.

  In this method, when the molding drum 1 is rotationally driven at the combined peripheral speed of the conveying speed of the conveyor belt 2 and the advance stroke speed of the conveyor belt itself, productivity can be improved by high-speed sticking. In addition, the possibility of a decrease in the accuracy of attaching the unvulcanized belt-like member W can be sufficiently removed under the synchronization of the speed.

  Here, when positioning the unvulcanized belt-like member W on the conveyor belt conveying surface is performed by adsorption of the unvulcanized belt-like member W to the belt conveying surface by negative pressure, magnetism or the like, Compared with the positioning by only the adhesion of the member W, the unintended displacement of the belt-like member W can be prevented, and the molding drum 1 sticking accuracy can be further increased.

  This also applies when the tip of the unvulcanized belt-like member W in the conveying direction is attached to the peripheral surface of the molding drum 1 by starting the sticking of the leading end in the conveying direction on the peripheral surface of the molding drum 1. The same is also true. According to this, for example, an unexpected misalignment on the drum peripheral surface of the sticking tip of the unvulcanized belt-like member W to be directly stuck on the peripheral surface of the molding drum 1. Etc. can be sufficiently prevented, and the accuracy of sticking can be improved.

Here, when the molding drum 1 is, for example, a belt-tread molding drum, each of a predetermined number of unvulcanized belt-like members W formed by burying cords extending in a desired form is preferably In the state where the butt joint between the sticking start end and the sticking end is offset in the drum circumferential direction, the belt member is formed by laminating and laminating in the same manner as described above, and then the unvulcanized belt shape By attaching unvulcanized tread rubber as the member W to the outer peripheral side of the belt member, a belt tread band is formed.
After that, the belt / tread band on the molding drum 1 is gripped from the outer peripheral side with an O-ring (not shown) and the molding drum 1 is deformed to reduce the diameter so that the belt / tread band is supported by the O-ring. Then, the belt / tread band is conveyed to the next predetermined work position, for example, the outer position of the former for shaping the green case, by O-ring or the like.
