Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a conveyor device for conveying a belt-shaped member made of rubber and steel cord such as carcass ply, steel belt, and chafer of an automobile tire to a molding drum of a tire molding machine.

[0002]

[Prior Art]

 In the manufacturing process of automobile tires, a belt-shaped member made of rubber and steel cord such as carcass ply, steel belt, chafer, etc. is placed on a conveyor belt and conveyed, and rubber tape, etc. is supplied from above during the process. It is practiced to stack and paste on a belt-shaped member, but on the belt-shaped member supply side of the conveyor belt used for such purpose, in order to correctly place the above-mentioned belt-shaped member on the center of the conveyor belt surface, There has been provided a supply guide including a support guide contacting the lower surface of the strip-shaped member and a width regulation guide contacting both side edges of the strip-shaped member.

[0003]

[Problems to be solved by the device]

 However, while the width of the belt-shaped member varies by about 1 to 2 mm, the conventional width regulation guide is fixed at a predetermined interval according to the width of the belt-shaped member, so that the belt-shaped member is conveyed. There was often meandering when riding on the belt, and the centerlines of both were often inconsistent. Further, since the belt-shaped member simply rides on the conveyor belt, the belt-shaped member may be displaced on the conveyor belt.

Particularly, when the steel cord in the strip-shaped member is inclined with respect to the length direction of the strip-shaped member, the flow direction of the strip-shaped member tends to be biased to one side, and the deviation of the center line becomes large. Therefore, there was a problem in that there was a deviation in the position where the rubber tape was attached. If the steel cord is tilted and the rubber tape feed position is adjusted according to the biased tendency, the above-mentioned feed position will be used when the strip-shaped member with the steel cord inclined in the opposite direction is conveyed. Had to readjust.

According to this invention, the belt-shaped member can be guided onto the conveyor belt with the center lines aligned, and the position of the belt-shaped member on the conveyor belt does not shift laterally. Provided is a conveyor device for a belt-shaped member for a tire, which is capable of attaching a rubber tape or the like to an accurate position on the belt-shaped member without causing the above-mentioned displacement even when the steel cord is inclined. It is a thing.

[0006]

[Means for Solving the Problems]

 The tire belt-shaped member conveying device according to the present invention is provided with a support guide that contacts the lower surface of the belt-shaped member supplied to the conveyor belt on the supply side of a horizontally running conveyor belt and a width regulation that contacts both side edges of the belt-shaped member. In the conveyor device for a tire belt-shaped member, the tire belt-shaped member made of rubber and steel cord is placed on the conveyor belt via the supply guide. It is characterized in that magnets are arranged along the lower surface on the outward path, and the width regulation guides are fixed on a pair of left and right sliding frames that are symmetrically slid left and right and are biased inward.

[0007]

[Action]

 The width-regulating guides contacting both side edges of the strip-shaped member slide symmetrically and are biased inward to provide a self-centering function, so even if the width of the strip-shaped member fluctuates, the center line Match the center line of the conveyor belt. Then, a magnetic force acts between the magnet provided along the lower surface of the conveyor belt on the outward path and the steel cord of the strip-shaped member on the upper surface of the conveyor belt on the outward path, and the magnetic force causes the belt-shaped member to move. Fixed on. Therefore, even when the steel cord is inclined, the belt-shaped member is not biased to one side of the conveyor belt.

【Example】

 In FIG. 1, reference numeral 1 is a conveyor belt for transporting the belt-shaped member K, which is horizontally wound between the front and rear pulleys 2 and 3, and a pulley 3 on the sending side (right side in FIG. 1) is chained by a motor 4 below. It is driven via the transmission mechanism 5 and rotates in the direction of arrow P. A lower roller 6 and an upper roller 7 for laminating are provided in the middle of the pulleys 2 and 3, and two rubber tapes Ta and Tb are supplied to the left and right of the nip portion from above together with the release tapes Ra and Rb. (See FIG. 3), the rubber tapes Ta and Tb are attached to the left and right side edge portions of the belt-shaped member K at this nip portion, and after passing through the nip portion, the release tapes Ra and Rb are replaced with the rubber tape Ta and Tb. It is peeled off from Tb and wound up. In addition, 8 and 9 are guide rollers.

As shown in FIG. 3, the lower roller 6 for laminating has a circumferential V groove 6a at the center in the width direction. Similarly, a V groove is also formed in the supply side pulley 2 and the delivery side pulley 3. Corresponding to these V-grooves 6a, a longitudinal ridge 1a that fits with the V-groove 6a is formed in the center of the back surface of the conveyor belt 1, and the pulleys 2 and 3 and the lower bonding roller 6 are attached. The displacement of the conveyor belt 1 with respect to the above is prevented. Further, a large number of magnets 10 are arranged along the lower surface of the conveyor belt 1 on the outward path, and the conveyor belt 1 runs along the upper surface thereof.

A supply guide 11 for supplying the belt-shaped member K to the conveyor belt 1 is arranged so that a plurality of horizontal guide rollers 12 are in contact with the back surface of the belt-shaped member K that obliquely rises from the floor on the supply side. And a width regulation guide formed by arranging vertical guide rollers 13 that are substantially perpendicular to the surface of the belt-shaped member K in two rows on the left and right sides so as to contact the left and right side edges of the belt-shaped member K. To be done. Instead of the horizontal guide roller 12, a short endless belt can be installed diagonally to serve as a support guide.

The details of the supporting means for the vertical guide roller 13 are shown in FIG. That is, upper and lower two guide rods 14, 14 are provided in the width direction below the uppermost horizontal guide roller 12, and the upper and lower guide rods 14, 14 straddle these two guide rods 14, 14. A pair of left and right sliding frames 15 and 15 are slidably provided, and left and right vertical frames 16 and 16 that bend along the path of the belt-shaped member K are provided on the left and right sliding frames 15 and 15, respectively. It is fixed, and the vertical guide rollers 13 are supported by the vertical frames 16, 16.

Therefore, the pins 17 are provided at two positions above and below the facing portions of the left and right sliding frames 15, 15. On the other hand, a support shaft 18 is provided between the left and right sliding frames 15 and 15, and two links 19 and 19 are attached to the support shaft 18 in a cross shape and rotatably at their respective central portions. The pins 17 are slidably inserted into the slots 20, 20 formed at both ends of the links 19, 19, respectively. Then, the string 22 connected to the one sliding frame 15 by the connecting tool 21 is hung downward via the pulley 24 attached to the support shaft 18, and the weight 23 is connected to the lower end thereof. Therefore, the left and right sliding frames 15 and 15 are biased inward by the weight 23, move symmetrically along the guide rods 14 and 14, and are automatically moved to the left and right vertical guide rollers 13 and 13. Gives alignment.

In the above structure, the belt-shaped member K is guided onto the conveyor belt 1 via the supply guide 11 and passed through the nip portion between the lower roller 6 and the upper roller 7 for bonding, and the driving motor 4 for the conveyor roller 1 is driven. When the winding rollers of the rubber tapes Ra and Rb are driven, the vertical guide rollers 13 and 13 are always displaced symmetrically following the fluctuation of the width of the belt-shaped member K, and the belt-shaped member K is guided to the center of the conveyor roller 1. The belt-shaped member K is accurately placed on the center line of the conveyor belt 1.

On the other hand, the conveyor belt 1 meanders to the left and right by fitting the protrusions 1 a on the back surface into the respective V grooves of the supply side pulley 2 and the sending side pulley 3 and the V groove 6 a of the lower roller 6. Run straight without doing. Since the belt-shaped member K placed on the conveyor belt 1 is fixed on the conveyor belt 1 by the magnetic force of the magnet 10 on the lower surface of the conveyor belt 1 on the outward path, the belt-shaped member K is conveyed without being laterally displaced, so that the rubber tape Ra , Rb are attached to the surface of the strip-shaped member K without being biased to the left and right.

Then, the strip-shaped member K to which the rubber tapes Ta and Tb are adhered has the release tapes Ra and Rb peeled off from the surface thereof, and then passes through the guide roller 25 on the delivery side and then the core (shown in the figure). It is not rolled up). The release tapes Ra and Rb separated from the rubber tapes Ta and Tb are wound up.

[0016]

[Effect of the device]

 As described above, this device has magnets arranged along the lower surface of the conveyor belt on the outward path, and the width-regulating guides contacting both side edges of the belt-shaped member on the conveyor belt supply side are symmetrically slid inward. Since it is fixed on a pair of left and right sliding frames that are biased, even if the steel cord of the belt-shaped member is inclined, the belt-shaped member can be accurately guided onto the conveyor belt without being biased to the left or right. The belt-shaped member can be fixed and transported without being displaced left and right on the conveyor belt. Therefore, when parts such as a rubber tape are stuck on the conveyor belt, the sticking positions do not become uneven, and it is not necessary to adjust the supplying position of the rubber tape every time the inclination direction of the steel cord changes.
