Description

The present invention relates to a guide device capable of accurately positioning and centering a band-shaped member with an edge tape to which an edge tape used for terminal processing of a band-shaped member such as a band-shaped steel member is attached.

In pneumatic tires, belt-shaped tire reinforcement members (steel members, etc.) containing multiple steel cords covered with rubber, such as belt layers, carcass layers, side reinforcement layers, finishing members (bead reinforcement layers, etc.) are used. Has been. These tire reinforcing members are generally formed by covering a plurality of steel cords and organic fiber cords with rubber to form a calendar material, and cutting the calendar material at a predetermined angle with respect to the longitudinal direction. A plurality of cut pieces are processed by joining them so that a cut end of a steel cord or the like is positioned at an edge portion.

Such a tire reinforcing member has a drawback that separation between rubber and a cord tends to occur because a cut end such as a steel cord is present at an edge portion. Therefore, an edge tape or rubber sheet made of the same material as the coating rubber of the tire reinforcing member is bonded to the edge portion of the tire reinforcing member to suppress the occurrence of separation at the edge portion and improve the durability of the pneumatic tire. I am doing so.

As a method for attaching a thin rubber sheet called an edge tape as a terminal treatment of such a band-shaped steel member or the like, there are two types of methods: U-turn bonding and flare bonding. FIG. 3 is a diagram schematically showing the structure of U-turn pasting and flare pasting. As shown in FIG. 3A, the U-turn bonding is performed by folding a rubber edge tape 112 in a U shape so as to cover the edge portion of the steel belt (steel member) 111. In this U-turn bonding, since the steel belt material 111 including the rubber edge tape 112 has high rigidity, a plate-shaped guide arranged in the edge direction (vertical shape) of the member as a method for positioning (centering) the member. A method of correcting with a plate or a free roller arranged vertically is generally used. For example, as shown in FIG. 3A, the plate-shaped guide plate 115 (115-1, 115-2) is pressed from the outside of the edge tape 112 (112-1, 112-2) to position the steel belt 111. And centering can be performed. (Patent Document 1)

On the other hand, as shown in FIG. 3 (b), flare attachment is a method of attaching edge tapes 113 and 114, which are two thin rubber sheets, to the edge portion of a steel belt from above and below, such as U-turn attachment. There is an advantage that a folding process and apparatus are unnecessary.

Japanese Patent Laying-Open No. 2005-041254 JP 2003-181949 A

However, with flare sticking, the end (edge) of the steel belt becomes a flexible thin rubber sheet. Therefore, the method using a plate-shaped guide plate used for U-turn sticking can provide accurate guidance. Can not. That is, as shown in FIG. 3B, in the case of flare bonding, the outer end portion 115 (115-1, 115-2) of the edge tape that is flare-attached has a flexible thin rubber sheet. Even if the edge tapes 113 (113-1, 113-2) and 114 (114-1, 114-2) are pressed from the outside with a plate-shaped guide as shown in 3 (a), these edge tapes may be bent. Deformed and cannot be positioned accurately.

Therefore, there is a method in which the end (edge tape) of the member is detected by a photo sensor, a camera or the like to perform positioning. For example, in Patent Document 2, a CCD camera that captures the state of a tread flowing on a conveyor, and the positions of both ends of the tread are detected from the captured image data to calculate the center position of the tread to perform centering of the tread. Although it is disclosed that this is applied, a method of positioning by detecting the end (edge tape) of a steel member with a flared edge tape by using a photo sensor or a camera is conceivable. However, this method does not detect a steel member terminal portion that is important for the characteristics of the tire, and thus has a problem of greatly affecting the accuracy of attaching the edge tape, and accurate positioning and centering are difficult. Furthermore, there is a problem that an apparatus and a special method for solving this problem are required, and as a result, more manufacturing time, labor, and cost are required, and the total cost is increased. In addition, in the prior literatures so far, there is almost no disclosure relating to positioning and centering methods and apparatuses for the strip-shaped member with the edge tape that is flared.

The present invention relates to a guide method capable of accurately aligning even a belt-like member with an edge tape in which a terminal part (edge part) such as a steel belt like flaring is covered with a flexible thin rubber sheet, and A guide device is provided. In order to solve the above problems, the present invention specifically has the following characteristics.
(1) The present invention relates to a stepped portion of a bonding portion of an edge tape that covers an end portion of the band-shaped member in the band-shaped member with an edge tape that is bonded to the end portion of the band-shaped member so as to sandwich the edge tape from above and below. The guide device is characterized in that the bonding portion between the edge tapes is positioned by being sandwiched between guide rollers disposed above and below the edge tape.
(2) In the present invention, the edge tape bonding portion is further positioned by pressing the end portion of the stepped portion in the center direction in the width direction of the belt-shaped member with guide rollers arranged above and below the edge tape. It is the guide apparatus characterized.

(3) In addition to (1) and (2), in the present invention, a plurality of upper guide rollers disposed above the edge tape are disposed in the moving direction of the belt-shaped member and are rotatable, and the lower side of the edge tape. A plurality of lower guide rollers arranged in the direction of movement of the belt-shaped member and are freely rotatable, and further, the gap and the inclination angle of the upper guide roller and the lower guide roller are adjusted according to the belt-shaped member and the edge tape. The guide device is characterized in that it can be adjusted, and in particular, can be adjusted in accordance with the thickness of the edge tape and the stepped portion in the bonded portion of the edge tape.
(4) In addition to (1) to (3), the present invention is such that the guide roller abuts on the stepped portion of the edge tape bonding portion of the band-shaped member with edge tape, and the guide roller rotates as the band-shaped member moves. In addition, the upper guide roller and / or the lower guide roller can be moved up and down in the vertical direction with respect to the belt-like member, whereby the gap between the upper guide roller and the lower guide roller The guide device is characterized in that the interval can be adjusted.

According to the guide device of the present invention, the edge tape is sandwiched by the guide roller from the upper and lower sides of the adhered edge tape at the step between the band-shaped member and the edge tape bonding portion at the end of the band-shaped member, and further the width of the band-shaped member. In the direction, the edge tape covering the end of the band-shaped member in the stepped portion is pressed in the width direction by the guide rollers arranged on both sides or one end of the band-shaped member, so that the band-shaped member can be accurately positioned. . Furthermore, since the guide rollers disposed on the top, bottom, left, and right of the belt-like member can adjust the gap between the guide rollers, they can be positioned corresponding to edge tapes and belt-like members having different thicknesses and widths. In the band member with edge tape manufactured by using flare bonding, the edge tape covering both ends of the band member is flexible, so that a sufficient positioning guide cannot be obtained. However, by using the guide device of the present invention, high accuracy is obtained. Positioning can be performed.

FIG. 1 is a diagram showing an example of a positioning guide device of the present invention. FIG. 2 is a diagram showing a guide device having a truncated cone-shaped guide roller. FIG. 3 is a diagram schematically showing the structure of U-turn pasting and flare pasting.

The present invention relates to a guide device for accurately positioning a flare-attached edge tape-attached band member to which a thin rubber sheet called an edge tape used as a terminal treatment of a belt-like member such as a belt-like steel member used at the time of tire manufacture is attached. About. FIG. 1 is a diagram showing an example of a positioning guide device of the present invention. The guide device 20 according to the present invention shown in FIG. 1 has upper and lower edges (12, 13 and 14, 15) which are attached to both ends of the belt-like member 11 so as to sandwich the tape from above and below (so-called flare bonding is performed). In the strip-shaped member 11 with two edge tapes, the bonding portion between the edge tapes is a step portion of the bonding portion of the edge tapes (12, 13 and 14, 15) covering both ends of the strip-shaped member 11. It is characterized by being sandwiched between guide rollers (21 and 22, and 23 and 24) arranged above and below the edge tape and positioned by pressing the end of the stepped portion in the width direction on the center side of the belt-like member 11.

Further, in the guide device 20 of the present invention shown in FIG. 1, the upper guide rollers (21, 23) arranged above the edge tapes (12, 14) are moved in the direction of movement of the belt-like member 11 (perpendicular to the paper surface in FIG. 1). ) And a plurality of lower guide rollers (22, 24) arranged below the edge tape (13, 15) are arranged in the movement direction of the belt-like member 11. The gap between the upper guide rollers (21, 23) and the lower guide rollers (22, 24) and the inclination angle are set so that the step portion of the belt-like member 11 with edge tape can be rotated. It can be adjusted according to the characteristics.

Further, in the guide device 20 of the present invention shown in FIG. 1, the belt-like member 11 is set on the conveyance table 16 and is perpendicular to the width direction of the belt-like member 11 (in FIG. 1, the surface from the back in the direction perpendicular to the paper surface). The belt-like member 11 is centered while the upper guide rollers (21, 23) and the lower guide rollers (22, 24) rotate in the movement direction according to the movement. And Further, in the guide device of the present invention shown in FIG. 1, the upper guide rollers (21, 23) and / or the lower guide rollers (22, 24) can be raised and lowered in the vertical direction with respect to the belt-like member 11, thereby It is characterized in that the gap between the upper guide rollers (21, 23) and the lower guide rollers (22, 24) can be adjusted.

As shown in FIG. 1, in the guide device 20 for positioning the belt-shaped member 11 according to the present invention, a pair of upper and lower guide rollers 21 and 22 are arranged on one end side in the width direction of the belt-shaped member 11 (left side in FIG. 1). The pair of upper and lower guide rollers 23 and 24 are arranged on the other end side (the right side in FIG. 1) in the width direction of the belt-like member 11. The belt-shaped member 11 is placed on the transport table 16 and is moved in a direction substantially perpendicular to the width direction of the belt-shaped member by the feed mechanism of the transport table 16 (in FIG. 1, the surface is perpendicular to the paper surface). Yes. As the feed mechanism of the transport table, various types such as a rotation roller, a belt conveyor, a rotation bearing, and a transport ball can be selected. Edge tapes 12 and 13 are attached to one end side (the left side in FIG. 1) in the width direction of the band-shaped member 11 to cover the edge (side surface) of the band-shaped member 11. The edge tape 12 is adhered to the inner upper surface from the edge (side surface) of the belt-shaped member, and the edge tape 13 is adhered to the inner lower surface from the edge (side surface) of the belt-shaped member. Further, the edge tape 12 (upper side) and the edge tape 13 (lower side) are directly attached outside the edge (side surface) of the belt-like member.

Accordingly, a stepped portion is formed at the edge (side surface) of the belt-like member 11 (the upper edge tape 12 has a stepped portion 43 at the edge (side surface), and the lower edge tape 13 has a stepped portion 44 at the edge (side surface)). Edge tapes 14 and 15 are adhered to the other end side (the right side in FIG. 1) in the width direction of the band-shaped member 11 to cover the edge (side surface) of the band-shaped member 11. These states are the same as those on the left side, and a step portion is formed at the edge (side surface) of the belt-shaped member 11 (the upper edge tape 14 is the step portion 31 at the edge (side surface), and the lower edge tape 15 is the step portion 32 at the edge (side surface). ) Is formed. The above edge tape application method is flare application.

In the guide roller 21, the rotating portion 25 of the guide roller 21 is placed on a base ball 26, and the base ball 26 is fixed to a support base 27. The rotation unit 25 of the guide roller 21 is rotatable with respect to the rotation axis 25 and the central axis (or center column) 28 of the base ball 26. In this structure, the pedestal ball 26 is fixed to the central shaft 28, and the rotating portion 25 of the guide roller 21 rotates around the pedestal ball 26. The central axis 28 of the guide roller 21 can be moved (rotated, etc.) with respect to the support 27, and the bottom surface 30 of the rotating unit 25 perpendicular to the central axis of the guide roller 21 and the width direction (horizontal plane) of the strip member 11. The angle β is determined by the base ball 26. The angle β can be varied, and the rotating portion 25 of the guide roller 21 can be rotated around the central axis 28 while keeping the angle β constant.

The support base 27 is fixed to the lateral movement support member 33, and the lateral movement support member 33 can be moved in the width direction (lateral direction or horizontal direction) of the belt-shaped member 11. By the movement of the lateral movement support member 33, the guide roller 21 can also laterally move while keeping the angle β constant. The movement of the lateral movement supporting member 33 can be moved in conjunction with the lower left lateral movement supporting member 34 and the movement of the right upper lateral movement supporting member 35 in conjunction with the lower right lateral movement supporting member 36. it can. Furthermore, centering can also be performed by interlocking movement of these lateral movement support members 34 to 36. For example, when the left upper moving member 33 and the right upper moving member 35 are interlocked and the left upper moving member 33 moves sideways by x, the right side upper moving member 35 is moved sideways by −x. Thus, the centers of the upper moving member 33 and the right upper moving member 35 do not move, and therefore centering is possible.

A lateral movement support member (left upper lateral movement support member) 33 is connected to a longitudinal movement support member (left upper longitudinal movement support member) 37, and the longitudinal movement support member 37 is perpendicular to the width direction of the strip member 11 (vertical direction). ), The lateral movement support member 33 can move in the direction perpendicular to the width direction of the belt-like member 11 in conjunction with the movement. That is, the guide roller 21 can move in the direction perpendicular to the width direction of the belt-like member 11, in other words, the guide roller 21 can be raised and lowered. Similarly, the lower left lateral movement support member 34 is connected to the lower left vertical movement support member 38, and the vertical movement support member 38 can move in the direction perpendicular to the width direction of the belt-like member 11. Thus, the lateral movement support member 34 can move in the direction perpendicular to the width direction of the belt-like member 11. That is, the guide roller 22 can move in the direction perpendicular to the width direction of the belt-like member 11, in other words, the guide roller 22 can move up and down.

The same applies to the right guide rollers 23 and 24. The upper right lateral movement support member 35 is connected to the upper right vertical movement support member 39, and the vertical movement support member 39 can move in the direction perpendicular to the width direction of the belt-like member 11. The support member 35 can move in the direction perpendicular to the width direction of the band-shaped member 11, and the guide roller 23 can move in the direction perpendicular to the width direction of the band-shaped member 11, in other words, the guide roller 23 can move up and down. The lower right lateral movement support member 36 is connected to the lower right vertical movement support member 40, and the vertical movement support member 40 can move in the direction perpendicular to the width direction of the belt-like member 11. The lateral movement support member 36 can move in a direction perpendicular to the width direction of the band-shaped member 11, and the guide roller 24 can move in a direction perpendicular to the width direction of the band-shaped member 11, in other words, the guide roller 24 can move up and down. .

As described above, the guide rollers 21 to 24 can be moved up and down individually in the direction perpendicular to the width direction of the band-shaped member 11 (longitudinal direction or up-down direction). Therefore, the guide rollers 21 to 24 can individually set the lifting distance (height). For example, the left and right guide rollers 21 and 23 or the left and right guide rollers 22 and 24 can be moved at the same height. It is also possible to move the guide rollers 21 and 22 or the guide rollers 23 and 24 by the same distance in the opposite directions so as to contact the edge tapes 12 to 15 at the same time or to release them simultaneously. Further, the gap between the upper and lower guide rollers 21 and 22 can be set and held at a predetermined interval, and the height of the gap can be set with high accuracy.

For example, the lowermost portion of the guide roller 21 (corresponding to the outer peripheral corner portion 29 of the rotating portion 25) can be lowered by the thickness of the edge tape 12 from the center height of the band-shaped member 11 and stopped at that position. Further, the uppermost portion of the guide roller 22 (corresponding to the outer peripheral corner portion 41 of the rotating portion 42) can be raised by the thickness of the edge tape 13 from the center height of the band-shaped member 11 and stopped at that position. Therefore, the edge tapes 12 and 13 are sandwiched between the outer peripheral corner portion 29 of the rotating portion 25 of the guide roller 21 and the outer peripheral corner portion 41 of the rotating portion 42 of the guide roller 22, and the edge tapes 12 and 13 are While being able to hold | maintain almost no pressure, the outer peripheral angle part 29 of the rotation part 25 of the guide roller 21 and the outer peripheral angle of the rotation part 42 of the guide roller 22 are further provided. The height of the intermediate position between 41 can coincide with the center height of the thickness of the belt-shaped member 11. The same operation can be performed for the guide rollers 23 and 24.

Further, the transport table 16 can also be adjusted (lifted / lowered) in the direction perpendicular to the width direction of the belt-shaped member 11 (vertical direction or vertical direction), and the belt-shaped member 11 on the transport table can be moved in the horizontal direction or the vertical direction. can do. Further, the transport table 16 can be tilted at a different angle with respect to the width direction of the belt-like member 11, and when the belt-like member 11 is tilted with respect to the horizontal, the transport stand 16 is changed to be in a horizontal state. can do.

As described above, since the guide roller of the present invention has the horizontal (horizontal) moving mechanism and the vertical (vertical up / down) moving mechanism, the upper and lower guide rollers can be arranged at desired positions. For example, the outer peripheral corner 41 of the left lower guide roller 22 is positioned at the same position of the lower edge tape 13 with respect to the position where the outer peripheral corner 29 of the left upper guide roller 21 is in contact with the upper edge tape 12. Can be contacted. In FIG. 1, four guide rollers 21 to 24 are arranged around the belt-like member 11 on the top, bottom, left and right. Multiple sets of guide roller groups are arranged. That is, a plurality of the same guide rollers as 21 are arranged in the moving direction of the belt-like member on the upper left side. A plurality of the same guide rollers as 22 are arranged in the moving direction of the belt-like member on the lower left side. Further, a plurality of the same guide rollers as 23 are arranged in the moving direction of the belt-like member on the upper right side, and a plurality of the same guide rollers as 24 are arranged in the moving direction of the belt-like member on the lower right side. . Positioning and centering of the strip-shaped member 11 with edge tape are performed using the four guide rollers in each set, and the strip-shaped member 11 with edge tape moves the transport table 16 from the back side to the front side.

Next, a method for positioning and centering the band-shaped member 11 with the edge tape will be described. The strip-shaped member 11 with the edge tape attached with the flare is placed on the carrier 16 and moved. In the flared edge tape, the upper and lower edge tapes (12 and 13, or 14 and 15 in FIG. 1) may be offset and bonded together, or may be bonded without offset. The strip-shaped member 11 with the edge tape attached with the flare is supplied as a long member wound around a reel. In that case, a strip-shaped long member wound off from the reel is guided to the conveyance table 16. Alternatively, the strip-shaped member 11 with the edge tape that has been flared may be a short strip-shaped member that is cut individually. In this case, the width direction of the strip-shaped member is aligned with the width direction of the transport table, and is mounted on the transport table. Just move it. The ends covered with the edge tapes on both sides in the width direction of the belt-like member are not placed on the transport table 16 because they are sandwiched from above and below by the guide rollers. Therefore, the width of the transport table 16 is designed to be smaller than the width of the belt-like member 11. In order to cope with strip-shaped members having various widths, the width of the transport base may be made variable so that the end side of the strip-shaped member is not placed on the transport base.

Before positioning the belt-shaped member 11, in the guide device 20 installed at a predetermined position of the transport table 16, the guide rollers 21 and 23 are vertically moved with the guide rollers 22 and 24 at a place straddling the transport table 16 in the width direction. It is in a separated state. An edge tape (on the left side is the edge tapes 12 and 13) affixed to both sides of the belt-like member 11 between the upper guide rollers 21 and 23 and the guide rollers 22 and 24 as the belt-like member 11 moves on the carriage. On the right side, edge tapes 14 and 15) are respectively arranged. Conversely, the guide rollers 21 to 24 may move and be arranged above and below the edge tape attached to the end of the belt-like member 11 on the transport table 16.

On the left side of the guide device 20, the upper guide roller 21 is disposed on the upper edge tape 12, and the lower guide roller 22 is disposed below the lower edge tape 13. In this state, the upper and lower guide rollers 21 and 22 are not in contact with the edge tapes 12 and 13. The position (horizontal position) of the outer peripheral corner 29 of the rotating part 25 and the outer peripheral corner 41 of the rotating part 42 (of the guide roller 22), which are the parts where the guide rollers 21 and 22 first contact, are substantially the same.

When the positions of the outer peripheral corners 29 and 41 are placed outside the end face of the belt-like member 11, the guide roller 21 is lowered to the upper surface of the edge tape 12 at the portion where the edge tapes 12 and 13 are directly attached. Contact. Further, the guide roller 22 rises and comes into contact with the lower surface of the edge tape 13 at a portion where the edge tapes 12 and 13 are directly attached. The operations of the guide rollers 21 and 22 are performed almost at the same time, and are controlled so as to be substantially the same when contacting each edge tape. Further, if the distance between the guide rollers 21 and 22 (equal to the interval between the outer peripheral corners 29 and 41) is set in advance from the thickness when the edge tapes 12 and 13 are adhered, the contact timing is almost the same. Accurately grasp. Alternatively, the contact timing can be grasped using a contact sensor.

Further, the intermediate height of the gap between the guide rollers 21 and 22 is preferably equal to the height at the intermediate position of the thickness of the belt-shaped member. In this way, even if the guide roller 21 is in contact with the upper surface of the edge tape 12 and the guide roller 22 is in contact with the lower surface of the edge tape 13, the pressure caused by being sandwiched between the guide rollers 21 and 22 is not affected. It can be hardly applied, and after that, when the guide rollers 21 and 22 are moved laterally while being in contact with the edge tape, it can be smoothly moved, and the side surface of the step portion of the edge tape can be pressed without difficulty. Become.

When the guide rollers 21 and 22 come into contact with the edge tapes 12 and 13, respectively, the lowering of the guide roller 21 and the rising of the guide roller 22 are stopped. Next, when the guide roller 21 is horizontally moved to the edge end face side of the belt-like member 11 (lateral movement in the width direction of the belt-like member 11), the outer peripheral corner portion 29 of the rotating portion 25 of the guide roller 21 contacts the edge tape 12. The outer peripheral corner portion 29 of the rotating portion 25 of the guide roller 21 comes into contact with the step portion 43 of the edge tape 12 that is laterally moved and adhered to the edge end surface of the belt-like member 11. The side surface of the stepped portion 43 of the edge tape 12 is soft because it is a thin rubber sheet, but the end portion of the band-shaped member 11 is exposed in the width direction inside the band-shaped member 11 because, for example, the steel cord is exposed, so that the band-shaped member 11 has a fairly high rigidity in the width direction. Accordingly, since the resistance force increases with respect to the horizontal movement of the guide roller 21 when contacted, the resistance force is detected by a sensor or the like to detect that the guide roller 21 has contacted the stepped portion 43 of the edge tape 12. be able to.

For example, when interlocked with the right guide roller 23, positioning becomes possible and centering is possible when both guide rollers 21 and 23 come into contact with the stepped portion and resistance to movement increases. Note that the side surface of the outer peripheral corner portion 29 of the rotating portion 25 of the guide roller 21 contacts the side surface portion of the stepped portion 43. Preferably, the tip end portion of the outer peripheral corner portion 29 of the rotating portion 25 of the guide roller 21 is the stepped portion. It is desirable to contact 43 corners (on the concave side).

Similarly to the case of the guide roller 21, when the guide roller 22 is horizontally moved to the edge end face side of the belt-like member 11 (lateral movement in the width direction of the belt-like member 11), the outer peripheral corner portion 41 of the guide roller 42 becomes the edge tape 13. The outer peripheral corner portion 29 of the rotating portion 25 of the guide roller 21 contacts the step portion 43 of the edge tape 13 adhered to the edge end surface of the belt-like member 11. The side surface of the stepped portion 44 of the edge tape 12 is soft because it is a thin rubber sheet. However, the end portion of the band-shaped member 11 is exposed in the width direction inside the band-shaped member 11 because, for example, the steel cord is exposed. 11 has a fairly high rigidity in the width direction. Accordingly, since the resistance force increases with respect to the horizontal movement of the guide roller 22 when contacted, the guide roller 22 can detect the step portion 44 of the edge tape 12 by detecting the resistance force with a sensor.

For example, when interlocked with the guide roller 24 on the right side, when both the guide rollers 22 and 24 come into contact with the stepped portion and the resistance to movement becomes large, positioning becomes possible and centering can be performed. The bottom surface side of the outer peripheral corner portion 41 of the rotating portion 42 of the guide roller 22 is in contact with the side surface portion of the stepped portion 44. Preferably, the tip portion on the bottom surface side of the outer peripheral corner portion 41 of the rotating portion 42 of the guide roller 22 is used. It is desirable to contact the corner (on the concave side) of the stepped portion 44.

Since the upper right guide roller 23 is arranged so that a guide roller having the same shape as the left guide roller 21 is left-right symmetric, the operation of the right guide roller 23 is symmetric with the left guide roller 21. Further, the lower right guide roller 24 is arranged so that the guide roller having the same shape as the left guide roller 22 is symmetrical, so that the operation of the right guide roller 24 is symmetrical with the left guide roller 22. It is. That is, it is as follows.

The upper guide roller 23 is disposed on the upper edge tape 14, and the lower guide roller 24 is disposed below the lower edge tape 15. In this state, the upper and lower guide rollers 23 and 24 are not in contact with the edge tapes 14 and 15, but the outer peripheral corners 47 and (the guide roller 24 of the guide roller 24) are portions where the guide rollers 23 and 24 first contact. ) The position (horizontal direction position) of the outer peripheral corner 49 of the rotating part 48 is substantially the same.

When the positions of the outer peripheral corners 47 and 49 are placed outside the end face of the belt-like member 11, the guide roller 23 is lowered to the upper surface of the edge tape 14 at the portion where the edge tapes 14 and 15 are directly attached. Contact. Further, the guide roller 24 rises and comes into contact with the lower surface of the edge tape 15 at a portion where the edge tapes 14 and 15 are directly attached. The operations of the guide rollers 23 and 24 are performed substantially simultaneously (in conjunction with each other), and are controlled so as to be substantially simultaneous when contacting the edge tapes. Also, if the distance between the guide rollers 23 and 24 (equivalent to the interval between the outer peripheral corners 47 and 49) is set in advance from the thickness when the edge tapes 14 and 15 are adhered, the contact timing is almost the same. Accurately grasp. Alternatively, the contact timing can be grasped using a contact sensor.

The intermediate height of the gap between the guide rollers 23 and 24 is preferably equal to the height at the intermediate position of the thickness of the belt-shaped member. In this way, even if the guide roller 22 is in contact with the upper surface of the edge tape 14 and the guide roller 24 is in contact with the lower surface of the edge tape 15, the pressure due to being sandwiched between these edge tapes by the guide rollers 23 and 24 is maintained. It can be hardly applied, and after this, when the guide rollers 23 and 24 are moved laterally while being in contact with the edge tape, smooth movement is possible, and the side surface of the step portion of the edge tape can be pressed without difficulty. Become.

When the guide rollers 23 and 24 come into contact with the edge tapes 14 and 15, respectively, the lowering of the guide roller 23 and the raising of the guide roller 24 are stopped. Next, when the guide roller 23 is horizontally moved to the edge end face side of the strip member 11 (moving in the width direction of the strip member 11), the outer peripheral corner portion 47 of the rotating portion 46 of the guide roller 23 comes into contact with the edge tape 14. The outer peripheral corner portion 47 of the rotating portion 46 of the guide roller 23 comes into contact with the step portion 31 of the edge tape 14 that is laterally moved and adhered to the edge end surface of the belt-like member 11. The side surface of the step portion 31 of the edge tape 14 is soft because it is a thin rubber sheet. However, the end portion of the band-shaped member 11 is exposed in the width direction inside the band-shaped member 11 because, for example, the steel cord is exposed. 11 has a fairly high rigidity in the width direction. Accordingly, since the resistance force increases with respect to the horizontal movement of the guide roller 23 when contacted, the resistance force is detected by a sensor to detect that the guide roller 23 has contacted the step portion 31 of the edge tape 14. Can do.

For example, when interlocked with the left guide roller 21, when both the guide rollers 21 and 23 come into contact with the stepped portion 31 and the resistance to movement becomes large, positioning becomes possible and centering can be performed. Note that the side surface of the outer peripheral corner portion 47 of the rotating portion 46 of the guide roller 23 contacts the stepped portion 31, but preferably, the tip end portion of the outer peripheral corner portion 47 of the rotating portion 46 of the guide roller 23 is the corner of the stepped portion 31. It is desirable to contact the part (on the concave side).

Similarly to the case of the guide roller 23, when the guide roller 24 is horizontally moved (moved in the width direction of the belt-like member 11) toward the edge end surface side of the belt-like member 11, the outer peripheral corner portion 49 of the guide roller 48 becomes the edge tape 15. The outer peripheral corner portion 49 of the rotating portion 48 of the guide roller 24 contacts the stepped portion 32 of the edge tape 15 that moves laterally while contacting the lower surface and is adhered to the edge end surface of the belt-like member 11. The side surface of the stepped portion 32 of the edge tape 15 is soft because it is a thin rubber sheet. However, the end portion of the band-shaped member 11 is exposed in the width direction inside the band-shaped member 11 because, for example, the steel cord is exposed. 11 has a fairly high rigidity in the width direction. Accordingly, since the resistance force against the horizontal movement of the guide roller 24 when contacted is increased, the resistance force can be detected by a sensor to detect that the guide roller 24 contacts the step portion 32 of the edge tape 15. .

For example, when interlocked with the left guide roller 22, positioning is possible and centering is possible when both guide rollers 22 and 24 come into contact with the stepped portion and resistance to movement increases. Note that the bottom surface side of the outer peripheral corner portion 49 of the rotating portion 48 of the guide roller 24 is in contact with the side surface portion of the stepped portion 32, but preferably the tip portion on the bottom surface side of the outer peripheral corner portion 49 of the rotating portion 48 of the guide roller 24. It is desirable to contact the corner (on the concave side) of the step 32.

Just as the upper and lower guide rollers 21 and 22 on the left side operate in an almost interlocking manner, the upper and lower guide rollers 23 and 24 on the right side also operate in an almost interlocking manner. Further, the left and right guide rollers 21 and 23 on the upper side also operate symmetrically while being substantially interlocked. In other words, it is desirable that the lowering timing of the left and right guide rollers 21 and 23 and the timing of contact with the edge tape are almost simultaneously performed. Furthermore, the timing and movement speed at which the left guide roller 21 moves in the horizontal direction toward the center side of the belt-like member 11 are almost the same as the timing and movement speed at which the right guide roller 23 moves in the horizontal direction toward the center side of the belt-like member 11. It is desirable that they are the same. As a result, the timing at which the outer peripheral corner portion 29 of the rotating portion 25 of the left guide roller 21 contacts the side surface portion 43 of the edge tape 12 and the outer peripheral corner portion 47 of the rotating portion 46 of the right guide roller 23 are The timing of contacting the step portion 31 can be substantially matched.

When the outer peripheral corner portion 29 of the rotating portion 25 of the left guide roller 21 comes into contact with the stepped portion 43 of the edge tape 12, the belt-like member 11 is pushed in the center direction. On the other hand, when the outer peripheral corner portion 47 of the rotating portion 46 of the right guide roller 23 comes into contact with the step portion 31 of the edge tape 14, the belt-like member 11 is pushed in the center direction. Therefore, both the left and right guide rollers 21 and 23 are in a state in which the edge end surface of the belt-like member 11 is pushed and pinched from the left and right to the center side of the belt-like member 11 with the edge tape interposed therebetween. As a result, the middle of the left and right guide rollers 21 and 23 becomes the center of the belt-like member, and the step portions 43 and 31 of the edge tapes 12 and 14 can be positioned, and centering is performed (the center position can be grasped). It will be.

Further, the left and right guide rollers 22 and 24 on the lower side also operate symmetrically while being substantially interlocked. That is, it is desirable that the timing of raising the left and right guide rollers 22 and 24 on the lower side and the timing of contact with the edge tape are also performed almost simultaneously. Furthermore, the timing and movement speed at which the left guide roller 22 moves in the horizontal direction toward the center side of the belt-like member 11 are almost the same as the timing and movement speed at which the right guide roller 24 moves in the horizontal direction toward the center side of the belt-like member 11. It is desirable that they are the same. As a result, the timing at which the outer peripheral corner portion 41 of the rotating portion 42 of the left guide roller 22 contacts the side surface portion 44 of the edge tape 13 and the outer peripheral corner portion 49 of the rotating portion 48 of the right guide roller 24 are The timing of contacting the step portion 32 can be substantially matched.

When the outer peripheral corner portion 41 of the rotating portion 42 of the left guide roller 22 contacts the stepped portion 44 of the edge tape 13, the belt-like member 11 is pushed in the center direction. On the other hand, when the outer peripheral corner portion 49 of the rotating portion 48 of the right guide roller 24 contacts the stepped portion 32 of the edge tape 15, the belt-like member 11 is pushed in the center direction. Therefore, both the left and right guide rollers 22 and 24 are in a state in which the edge end surface of the band-shaped member 11 is sandwiched by pressing the band-shaped member 11 from the left and right to the center side of the band-shaped member 11 with the edge tape interposed therebetween. As a result, the middle of the left and right guide rollers 22 and 24 became the center of the belt-like member, and the step portions 44 and 32 of the edge tapes 13 and 15 were positioned, and centering was performed (the center position could be grasped). It will be.

As described above, the belt-shaped member 11 can be positioned and centered by the left and right guide rollers 21 and 23 on the upper side, and the belt-shaped member 11 can be positioned and centered by the left and right guide rollers 22 and 24 on the lower side. Can do. Further, the positioning and centering can be reliably performed by interlocking all the four guide rollers 21 to 24. However, since pinching from above and below is indispensable, for example, if only the upper guide roller contacts the edge tape and the lower guide roller does not contact the edge tape, the edge tape is formed of a soft rubber sheet or the like Therefore, the contact position of the upper guide roller with the edge tape is not fixed, and it is difficult to move the upper guide roller in the horizontal direction while contacting the edge tape, so that accurate positioning and centering can be performed. Can not. That is, it is desirable that the outer peripheral corner of the upper guide roller and the outer peripheral corner of the lower guide roller have substantially the same position in the horizontal direction to sandwich the edge tape.

In the above method, the middle position between the left and right guide rollers is the center position of the belt-shaped member, but the center position may not be determined. For example, when the band-shaped member 11 is first placed on the transport table 16, if the center position is shifted, there is a possibility that positioning or centering is performed as it is. Further, when one of the left and right guide rollers first contacts the step portion of the edge tape, the guide roller may push the band member and shift the position of the band member. In order to prevent this, the left and right guide rollers may be moved in synchronism so that the intermediate position between the left and right guide rollers is always at the center of the transport table 16. That is, the intermediate position of the first left and right guide rollers is set at the center of the carriage 16 so that the horizontal movement directions of the left and right guide rollers are opposite to each other, and the movement distances are always equal. Just do it.

For example, the middle position of the left and right guide rollers 21 and 23 on the upper side is made coincident with the center position C of the transport table 16, and the left guide roller 21 is moved on the edge tape 12 toward the center C of the belt-like member by x in the horizontal direction. The right guide roller 23 moves on the edge tape 14 toward the center C of the belt-like member by a distance x in the horizontal direction. In this way, the intermediate position between the left and right guide rollers 21 and 23 always coincides with the center position C of the transport table 16. If a free roller or a free bearing is arranged on a part of the transport table 16, even if the center of the belt-like member 11 is not initially placed at the center position C of the transport table 16, either the left or right guide roller 21 or 23 is used. First contacts the step portion of the edge tape and pushes and moves the belt-like member 11 toward the center position C. As a result, the left and right guide rollers 21 and 23 simultaneously contact the step portion of the edge tape. At the time of simultaneous contact, the belt-like member is placed so that the center in the width direction is the center position C of the carrier 16.

Even if the transport table 16 does not use a free roller or the like, the center of the strip member 11 can be made coincident with C if the strip member 11 can move the transport table 16 freely in the width direction. For example, in the case of belt conveyance, it is sufficient that the belt-like member is easily slid on the belt with a slight force in the lateral direction. Further, the left and right guide rollers 22 and 24 on the lower side can be set in the same manner as described above, so that the center position of the belt-like member can be set to the center position of the transport table by the guide rollers 22 and 24. Thus, by providing the transport table 16 also with a centering mechanism (a mechanism for freely moving in the width direction), the belt-shaped member can be positioned and centered in conjunction with the guide roller group.

Preferably, the upper guide roller is inclined in the horizontal direction, and the lower guide roller is inclined in the vertical rotation or the vertical rotation. As a result, positioning, centering and movement of the belt-shaped member become smoother. Since the bottom surface 30 of the rotating unit 25 in the guide roller 21 is a vertical surface with respect to the central axis 28 of the rotating unit 25 and the base ball 26, the bottom surface 30 and the horizontal plane are not affected even when the rotating unit 25 rotates around the central axis 28. The angle β formed by is constant. Further, since the bottom surface 51 of the rotating portion 42 in the guide roller 22 is a vertical surface with respect to the central axis 52 of the rotating portion 42, even if the rotating portion 42 rotates around the central axis 52, The formed angle α is constant. In order to perform positioning and centering by effectively pressing the stepped portion 43 of the edge tape 12 at the outer peripheral corner portion 29 of the rotating portion 25 of the guide roller 21, the range of β is in the range of 35 ° to 45 °, preferably About 40 degrees is good. (Because the rotating portion 25 having an angle γ of the outer peripheral corner portion 29 of about 45 degrees is used, the range of β + γ is 80 to 90 degrees, preferably about 85 degrees.) The rotating portion of the guide roller 22 In order to perform the positioning and centering by effectively pressing the step portion 44 of the edge tape 13 at the outer peripheral corner portion 41 of 42, the range of α is in the range of 0 to 10 degrees, preferably about 5 degrees. By setting the range of α and β in this way, the tip end portion of the outer peripheral corner portion of the guide roller effectively contacts the corner portion (concave portion side) of the step portion. In addition, the guide roller rotates while the tip of the corner portion of the outer periphery of the guide roller hits the corner portion (concave side) of the stepped portion with respect to the belt-like member that moves within this range, and the belt-like member moves smoothly. Can continue. Since the guide roller 23 is symmetrical with the guide roller 21, the range of β is applied. Further, since the guide roller 24 is symmetrical with the guide roller 22, the range of α is applied.

FIG. 2 shows an embodiment using a guide roller different from FIG. That is, FIG. 2 is a diagram showing a guide device having a truncated cone guide roller. The same members as those in FIG. 1 are denoted by the same reference numerals. In the guide device 60 shown in FIG. 2, on the upper side of the belt-shaped member 11 with edge tapes (12, 13, 14, 15) flared on both side end portions in the width direction of the belt-shaped member 11 arranged on the transport table 16 A left guide roller 61 and a right guide roller 66 are disposed on the lower side, and a left guide roller 62 and a right guide roller 64 are disposed on the lower side. In the guide roller 61, the rotating portion 71 has a truncated cone shape and is directly or semi-fixed to the support base 27. The truncated cone-shaped rotating part 71 is rotatable around the rotating part central axis 76, and the bottom surface 73 of the truncated cone-shaped rotating part 71 is perpendicular to the rotating part central axis 76. The angle β formed by the bottom surface 73 and the horizontal plane is constant even when the truncated cone-shaped rotating part 71 rotates around the rotating part central axis 76.

This angle β can be changed by moving (for example, rotating) the position of the frustoconical rotary part 71 on the support base 27 and changing the fixed angle between the rotary part central axis 76 and the support base 27. it can. If the optimum angle for positioning the belt-like member 11 is selected and fixed, β becomes constant. Alternatively, β can also be changed by changing the fixing angle between the lateral movement support member 33 to which the support base 27 is fixed and the support base 27. The outer peripheral corner 72 of the frustoconical rotating part 71 is between the edge tape 12 and the outer peripheral corner 75 of the frustoconical rotating part 74 of the lower guide roller 62 in the recess of the stepped part 43 of the edge tape 12. 13 is further sandwiched, and the side surface portion of the stepped portion 43 of the edge tape 12 (preferably, the corner portion (on the concave portion side) of the stepped portion 43) is pressed to position and center the belt-like member 11. That is, since the angle γ of the outer peripheral corner portion 72 of the frustoconical rotating portion 71 is constant, the outer peripheral corner portion 72 of the frustoconical rotating portion 71 abuts on the stepped portion 43 of the edge tape 12 and The belt-shaped member 11 can be positioned and centered while rotating in the rotational direction shown in FIG. 2 according to the movement of the belt-shaped member 11.

In the guide roller 62, the rotating portion 74 has a truncated cone shape and is directly or semi-fixed to the support base 53. The frustoconical rotating portion 74 is rotatable around the rotating portion central axis 76, and the bottom surface 73 of the frustoconical rotating portion 71 is perpendicular to the rotating portion central axis 77. The angle α formed between the bottom surface 78 and the vertical axis is constant even when the frustoconical rotation part 74 rotates around the rotation part central axis 77.

This angle α can be changed by moving (for example, rotating) the position of the frustoconical rotation part 74 on the support base 53 and changing the fixed angle between the rotation part central axis 77 and the support base 53. it can. If the optimum angle for positioning the belt-like member 11 is selected and fixed, α becomes constant. Alternatively, α can also be changed by changing the fixing angle between the lateral movement support member 34 to which the support base 53 is fixed and the support base 53. The outer peripheral corner 75 of the frustoconical rotating portion 74 is the recess of the stepped portion 44 of the edge tape 13 and the edge tapes 13 and 12 between the outer peripheral corner 72 of the frustoconical rotating portion 71 of the upper guide roller 61. Further, the belt-shaped member 11 is positioned and centered by pressing the side surface portion of the stepped portion 44 of the edge tape 13 (preferably, the corner portion (on the concave portion side) of the stepped portion 44). That is, since the angle δ of the outer peripheral corner portion 75 of the frustoconical rotating portion 74 is constant, the outer peripheral corner portion 75 of the frustoconical rotating portion 74 abuts on the stepped portion 44 of the edge tape 13, and Positioning and centering of the belt-like member 11 can be performed while rotating in the rotation direction shown in FIG. 2 according to the movement of the belt-like member 11 (movement from the back of the paper surface to the surface side).

The guide roller 63 has a symmetrical relationship with the guide roller 61 and has the same shape and structure, and its operation also operates in a symmetrical positional relationship with the guide roller 61. The outer peripheral corner portion 67 of the truncated cone-shaped rotating portion 66 of the guide roller 63 is an edge between the concave portion of the step portion 31 of the edge tape 14 and the outer peripheral corner portion 69 of the truncated cone-shaped rotating portion 68 of the lower guide roller 64. The band-shaped member 11 is positioned and centered by sandwiching the tapes 14 and 15 and pressing the side surface portion (preferably, the corner portion (on the concave portion side) of the step portion 31) of the edge tape 14. Since the angle of the outer peripheral corner portion 67 of the frustoconical rotating portion 66 is constant, the outer peripheral corner portion 67 of the frustoconical rotating portion 66 abuts on the stepped portion 31 of the edge tape 14, and the belt-like member 11 on the transport base 16. The belt-shaped member 11 can be positioned and centered while rotating in the rotational direction shown in FIG.

The guide roller 64 has a symmetrical relationship with the guide roller 62 and has the same shape and structure, and its operation also operates in a symmetrical positional relationship with the guide roller 62. The outer peripheral corner 69 of the truncated cone-shaped rotating portion 68 of the guide roller 64 is an edge tape between the concave portion of the stepped portion 32 of the edge tape 15 and the outer peripheral corner 67 of the truncated conical rotating portion 66 of the upper guide roller 63. 15 and 14 are sandwiched, and the side surface portion of the step portion 32 of the edge tape 15 (preferably, the corner portion (on the concave portion side) of the step portion 32) is pressed to position and center the belt-like member 11. Since the angle of the outer peripheral corner portion 69 of the frustoconical rotating portion 68 is constant, the outer peripheral corner portion 69 of the frustoconical rotating portion 68 abuts on the stepped portion 32 of the edge tape 15, and the belt-like member 11 on the transport base 16. The belt-shaped member 11 can be positioned and centered while rotating in the rotational direction shown in FIG.

As described with reference to FIG. 1, in order to quickly and accurately position and center the band-shaped member 11, the range of β is 35 to 45 degrees (γ is about 45 degrees), preferably about 40 degrees. Alternatively, the range of β + γ is 80 to 90 degrees, preferably about 85 degrees. The range of α is 0 to 10 degrees, preferably about 5 degrees. As can be seen from FIG. 1 and FIG. 2, the rotating part of the guide roller used in the present invention is such that the outer peripheral corner of the rotating part sandwiches the edge tape at the concave part of the step part of the edge tape, and the outer peripheral corner of the rotating part is stepped. A structure that can touch the side of the part or close to contact, and when the rotating part of the guide roller rotates, the outer peripheral corner of the rotating part always contacts the step part at a constant angle. If it is, the thing of various shapes can be used.

The present invention is a guide device capable of positioning and centering a strip-shaped member with edge tape that is flared, but the upper and lower edge tapes are insufficiently adhered to the end surface of the strip-shaped member, for example, between the upper and lower edge tapes. Even when there is a gap, or when the gap between the end surface of the belt-like member and the edge tape is not sufficiently adhered, the guide roller of the present invention moves while sandwiching the edge tape and moves the step side portion at the step portion. Since it is pressed, insufficient adhesion of the upper and lower edge tapes can be brought into close contact again, and the belt-like end portion of the stepped portion and the insufficient adhesion of the edge tape can be brought into close contact again, so that the adhesion can be reliably corrected. There is also an effect. 1 and 2 show a band-shaped member with edge tape bonded to both end portions of the band-shaped member (both sides), but edge tape is bonded to only one side of the band-shaped member (one side). The guide device of the present invention can also be applied to a belt-like member with an edge tape. In that case, a guide device in which a guide roller is arranged only on one side matched with the edge tape on one side may be used.

In addition, it cannot be overemphasized that the said content can be applied to the said other part regarding that it can apply without contradiction also to the other part which did not describe the content described and demonstrated in a certain part of the specification. Furthermore, the said embodiment is an example, and can be implemented in various changes within the range which does not deviate from a summary, and it cannot be overemphasized that the right range of this invention is not limited to the said embodiment.

The belt-shaped member guide device of the present invention can be applied to positioning and centering of a band-shaped member with an edge tape that is flared, and can be used for an end guide for finishing, a terminal guide for a long belt-shaped member, and the like. .
