Description

  The present invention relates to a take-up reel that winds up a long member.

  Conventionally, in a tire manufacturing process, a long member, for example, a long tire constituent member made of an unvulcanized rubber member such as a tread or a side rubber manufactured in a predetermined previous process is intermediated until it is assembled as a tire in a molding process. The product is wound and stored on a take-up reel.

For example, when winding an unvulcanized rubber member around a take-up reel, in order to wind the tip portion of the unvulcanized rubber around the take-up reel, not only positioning of the tip is required, but also the tip is taken up. It is necessary to attach to the cylindrical core. For this purpose, the rubber member must be guided to the core of the reel and wound around it.
However, apart from the case where the rubber member itself has tackiness (adhesive force), otherwise, even if the tip of the rubber member is brought into contact with the core of the take-up reel, the tip cannot be wound only by sliding.
For this reason, conventionally, winding is performed using a liner.
That is, for example, as shown in FIG. 5A, the liner L is fastened to the take-up reel D by any fastening means such as adhesion, and the tip of the rubber member 20 is placed on the liner while winding the liner L, It is guided to the take-up core C, where it is wound around the cylindrical core C of the take-up reel D together with the liner L so as to be taken up.

  The other method is basically the same as the above-described apparatus. However, as shown in FIG. 5B, the liner L is used for several meters at the beginning of winding, for example, the rubber member 20 winds up, and the reel D After winding around the core C, only the rubber member 20 is wound up without the liner L interposed.

  Further, as another method, a so-called naked winding is not required without using a liner, and when the rubber has a tackiness, a guide CV (conveyor belt) shown in FIG. 5C is used. This is because the conveyor belt CV is swingably disposed in the vicinity of the take-up reel D, and when the rubber member 20 is taken up, the conveyor belt CV is swung at a position close to the core C of the take-up reel D. In this state, the tip of the rubber member 20 sent out is received and conveyed by a conveyor belt, and acts so as to contact the cylindrical core C, thereby adhering the rubber member 20 onto the core C (stopping). Wear) and take up.

By the way, in the winding device using the conventional liner, it is necessary to wind up the rubber member and the liner, which are the tire constituent members drawn out from the two systems, so that the reel does not sag.
As a specific example, the tension of each of the tire constituent member (rubber member) and the liner is controlled independently, and the belt-like tire constituent member is interposed with the liner so as to be wound with high accuracy without causing winding looseness or collapse of the mold. A control method is known (Patent Document 1).
However, when the liner is used, the cost of the liner itself is required, but there is a problem that an apparatus for independently controlling the tension of the liner and the rubber member is required, and various costs such as the cost of the apparatus itself and the management cost are required.
In addition, since the use of the induction conveyor without the liner is limited to the case where the rubber member (tire constituent member) has a tackiness, the range of use is limited, and the induction conveyor and the control device for controlling the induction conveyor are limited. Therefore, there is a problem that various costs such as the cost of the apparatus itself and the management cost are required.
Japanese Patent Laid-Open No. 9-240893

  In order to solve the above-described conventional problems, an object of the present invention is to provide a take-up reel capable of easily and easily winding a belt-like sheet without using a special dedicated member as in the prior art.

In order to achieve the object of the present invention, the take-up reel according to claim 1 is a take-up reel for taking up a long member supplied from a predetermined direction from the front end side,
A pair of plates opposed to each other in a separated state, and a plurality of columnar members arranged between the plates and arranged circumferentially, with a long member inserted between the columnar members adjacent to each other, The long member is wound up by rotating a pair of plates integrally with the plurality of columnar members.
The take-up reel according to claim 2 is the take-up reel according to claim 1, wherein the plurality of columnar members are arranged such that a long rubber tip is between the columnar members adjacent to each other and between the pair of plates. A long member is wound up by rotating the pair of plates integrally with the plurality of columnar members while penetrating between the columnar members adjacent to each other across the column.
The take-up reel according to claim 3 is the take-up reel according to claim 1 or 2, wherein the plurality of columnar members are arranged at equal distances from the center of the pair of plates and at equal intervals. It is characterized by.
The take-up reel according to claim 4 is the take-up reel according to any one of claims 1 to 3, wherein the long member is a sheet-like or bar-like rubber, and a separation distance between the pair of plates Is wider than the width of the rubber.

According to the take-up reel of the present invention, a long member supplied from a predetermined direction is inserted between a plurality of columnar members constructed so as to surround the centers of a pair of plates facing each other in a separated state, and in that state Since the pair of plates are integrally rotated with the plurality of columnar members to wind the long member, the long member can be wound without using a special positioning engagement member such as a liner feeding device or a guide conveyor belt. This is possible, and the cost (running cost) can be reduced without using a liner as in the prior art. Further, unlike the case where a liner is used, it is not necessary to individually control the long member and the liner, or since there is no need for an induction conveyor belt or the like, the apparatus cost (initial cost) can be reduced.
According to the take-up reel according to claim 2, the plurality of columnar members are paired in a state in which the ends of the long members are also penetrated between the columnar members adjacent to each other across the centers of the pair of plates. By rotating the plate integrally with the plurality of columnar members, the long member at the initial stage of winding can be more reliably wound.
According to the take-up reels of claims 3 and 4, by forming the plurality of columnar members into cylindrical bodies arranged at equal distances from each other at the same distance from the center of the pair of plates, When a rod-shaped unvulcanized rubber) is wound around a take-up reel by simply inserting it between adjacent columnar members and inserting it between any adjacent columnar members facing each other across the center of a pair of plates Is easy to operate.

  Next, an example of the take-up reel of the present invention will be described with reference to the drawings, taking as an example the case of winding a belt-like rubber member.

  1 is a perspective view of the take-up reel of the present invention, FIG. 2A is a plan view of the take-up reel of the present invention, and FIG. 2B is a plan view of a modification of the take-up reel of the present invention.

  As shown in FIG. 1, the reel body 11 has a pair of disk-like plates 17 facing each other in a separated state and a center of the plate 17 so as to form a space inside instead of a conventional cylindrical core C. It consists of a plurality of columnar members 18 installed between the plates 17 so as to surround them.

Here, the columnar member 18 is made of, for example, a square pipe, a round pipe, a flat bar, and the like. FIG. 2A is, for example, arranged at an equal distance from the center (= rotation center) of the pair of plates 17 and at an equal interval. Of a square pipe. The number and arrangement interval (thickness) of the columnar members 18 are determined depending on the type and material of the belt-like sheet 20 to be wound, but by forming a large number of gaps between the columnar members 18, The need for positioning can be virtually eliminated.
FIG. 2B shows a round pipe shape which is another embodiment of the columnar member 18. Its function is the same as that of a square pipe.

  FIG. 3 (A) is an explanatory view of the main part showing the relationship between the winding reel of the present invention and the leading end of the belt-like sheet, and FIG. 3 (B) is a main part at the initial stage of winding the belt-like sheet by the winding reel of the present invention. It is explanatory drawing. In the above configuration, when the leading end 20a of the belt-like sheet 20 is fed by the feeding roller 21 that is rotated by driving the front CV motor 15 (FIG. 4), as shown in FIG. 2A, the leading end 20a is adjacent to the front side. It is inserted into the gap between the members 18.

  Reference numeral 12 denotes a detection sensor for detecting the tip of the rubber member. The detection sensor is provided on the winder side, and includes, for example, a light emitting element and a light receiving element arranged in a direction orthogonal to the insertion direction of the belt-like sheet 20, and the insertion side columnar member of the belt-like sheet 20 and the plate 17 A detection area is provided on the exit side of the belt-like sheet of the columnar member on the opposite side across the center. The detection sensor detects that the rubber member (sheet member) reaches the detection area and blocks the light from the light emitting element, outputs a detection signal, and performs control for winding described later. Instead of this detection sensor, the leading end position of the belt-like sheet 20 may be detected based on the estimation of the feeding amount by a timer or the estimation of the feeding amount of the belt-like sheet 20 by a pulse motor or the like.

  The inserted belt-like sheet 20 passes between adjacent columnar members 18 on the opposite side to the insertion side with respect to the center of the plate 17, and the tip 20 a is detected by the detection sensor 12 (see FIG. 3A). When the belt-like sheet is detected by the detection sensor, the feeding of the belt-like sheet 20 by the feeding roller 21 is temporarily stopped, and the winding motor 13 and the feeding roller 21 are driven synchronously (the feeding roller 21 may be stopped), As shown in FIG. 2B, the take-up reel is rotated to wind the leading end portion of the belt-like sheet 20 around the columnar member 18, and the take-up is started.

FIG. 4 is a block diagram of the belt-like sheet winding device of the present invention configured to realize the above operation.
In FIG. 4, the belt-shaped winding device 10 controls a belt-shaped sheet leading edge position detection sensor 12 provided on the reel body 11, a winding motor 13 that rotates the reel body 11, and the winding motor 13. A drive circuit 14 and a control circuit 16 that controls the drive circuit 14 based on a detection signal from the detection sensor 12 and a drive signal from a feeding motor 15 for feeding the belt-like sheet are provided.
In the belt-shaped winding device 10, when the detection sensor 12 detects the position of the belt-shaped sheet leading edge that passes between the columnar members 18 and comes out between the opposite columnar members 18, the control circuit receives the detection signal from the detection sensor 12. 14 controls the drive circuit 14 of the winding motor 13 and starts winding the belt-shaped sheet by the winding motor 13. At that time, the control circuit 14 drives and controls the take-up motor 13 to take up the belt-like sheet with the reel body 11 while applying an appropriate tension in synchronism with the feeding speed based on the drive signal from the front CV motor 15. To do.

  By the way, when the belt-like sheet 20 is a belt-like tire constituent member made of an unvulcanized rubber member such as a tread or a side rubber produced in a predetermined pre-process in the tire manufacturing process, until it is assembled as a tire in a subsequent molding process. Is wound around the reel body 11 as an intermediate product.

Therefore, the belt-like sheet 20 as an intermediate product in the tire manufacturing process wound around the reel main body 11 does not include the liner described in the prior art, so the cost reduction associated with not using the liner is realized. In addition to being able to reduce the weight and radial thickness by not using a liner, the distribution / conveying process (for example, shipping from a primary production factory to a secondary production factory) It is possible to contribute to reduction in size and weight in lift transportation in the same factory.
In the above description, the elongate member has been described as having a strip shape, but the shape thereof may be a round bar or a bar having an arbitrary cross-sectional shape.
