Description

  The present invention relates to an apparatus for supplying a belt-like member, and more specifically, the belt-like rubber-like elastic member wound around a highly rigid belt-like liner is securely peeled from the belt-like liner without being deformed at a constant speed. The present invention relates to a supply device for a strip-shaped member that can be supplied to the molding machine side.

  Conventionally, in a tire molding process or the like, when storing an unvulcanized belt-like rubber-like elastic member such as a tire tread or a side rubber molded by an extrusion device until the time of tire molding, a rubber-like elastic member cut into a fixed length Is stored in a multi-stage on a cart called a kerry truck, and the cart is transported to a molding machine when a rubber-like elastic member is used.

  In recent years, the unvulcanized belt-shaped rubber-like elastic member that has been molded and extruded is not cut into a fixed length, but a thin ribbon-shaped winding liner made of resin or a predetermined height on both side edges of the surface in the width direction. A metal belt-shaped take-up liner provided with a crosspiece is wound into a roll shape, and a rubber-like elastic member is unwound just before use during molding and cut to a fixed length and supplied to the molding machine side. (For example, refer to Patent Document 1 and Patent Document 2).

  By the way, when a belt-like rubber-like elastic member wound up in a roll shape with the take-up liner as described above is unwound and supplied to a molding machine, the unvulcanized rubber is supplied from the take-up liner. There is a problem that it is difficult to exfoliate the elastic elastic member with probability, and it is difficult to unwind the elastic elastic member at a constant speed without applying tensile deformation to the elastic elastic member.

In particular, a winding liner in which a belt-like rubber-like elastic member is wound up by a belt-like liner with a crosspiece has a problem that it has a large winding diameter and is difficult to unwind while controlling the rotation speed according to the liner diameter. .

It is comprised with the some free roller 19 arrange | positioned freely.

  Further, as shown in FIGS. 8 and 9, the outer diameters of the plurality of free rollers 19 are formed smaller than the outer diameter of the peeling roller 17, and as a result, the rubber-like elastic member W is formed from the belt-like liner Rx. 7 and 9, the peeling roller 17 is in contact with the belt-shaped liner surface Ra, and the free roller 19 is unwound in contact with the surface of the belt-shaped liner Rx. It is.

  Further, the base end portion of the swing frame 16 to which the peeling roller 17 and the plurality of free rollers 19 are attached is located behind the peeling roller 17 and the plurality of free rollers 19 as shown in FIGS. The support shaft 22 that supports the pair of left and right drive rollers 20a and 20b and the guide roller 21 disposed therebetween is supported so as to be swingable so as to be swing support points. One end side of 22 is connected to the driving sprocket 22a and the distal ends of a pair of left and right support frames 23 of the member conveying device 11.

  The pair of left and right drive rollers 20a and 20b are always in contact with the surface of the belt-like liner Rx, rotate following the unwinding of the belt-like liner Rx, and rotate to the drive roller 24 of the member conveying device 11 described later. Are transmitted synchronously.

  The base ends of the pair of left and right support frames 23 are supported so as to be swingable about a support shaft 26 provided on the support member 25. The support frame 23 includes a guide free roller 27 and a plurality of the drive units. A roller 24 and a plurality of rotatable transport rollers 28 are arranged in parallel at a predetermined interval.

It is configured to transmit the rotational driving force to the driving roller 24 of the member conveying device 11 when rotated following the take-out. Thereby, the unwinding speed of the rubber-like elastic member W unwound from the belt-like liner Rx and the member conveying speed of the member conveying device 11 are synchronized, and the member is conveyed to the next step without being excessively pulled and deformed. Is something you can do.

  The tip of the rod 15a of the lifting / lowering means 15 such as the cylinder is connected to the support frame 23 via a bracket 31, and the bracket 31 is provided with a buffer such as a gas-filled spring disposed under the support frame 23. The member 32 is connected.

  Next, a method for peeling the rubber-like elastic member W from the belt-like liner Rx using the member peeling means 9 as described above will be described.

  In this embodiment, a belt-like liner R2 in which a belt-like liner Rx around which a rubber-like elastic member W is unwound is wound on the left side of the transport carriage 1 in FIG. 1 and a rubber-like elastic member W on the right-hand side is shown as a belt-like liner Rx. The unrolling belt-like liner R1 wound in a roll shape is shown, and a method of unwinding the rubber-like elastic member W from the unwinding belt-like liner R1 will be described below.

  When the rubber-like elastic member W is peeled off from the belt-like liner Rx of the unwinding belt-like liner R1 and unwound, it always comes into contact with both sides in the width direction of the unwinding belt-like liner R1 as the unwinding belt-like liner R1 is driven to rotate. The rubber-like elastic member W is unwound by the pair of left and right peeling rollers 17 rotating and the non-contact free roller 19 disposed coaxially between the peeling rollers 17 and the surface of the belt-like liner Rx of the belt-like liner R1. Unwind while peeling.

  When the rubber-like elastic member W is peeled off from the belt-like liner Rx and unwound, the pair of left and right peeling rollers 17 are always brought into contact with the surface of the belt-like liner Rx, so that the free roller 19 can be removed from the belt-like liner R1. A non-contact state at a constant interval can be maintained from the surface of the belt-like liner Rx without being affected by a change in the outer diameter, so that a constant peeling force can be maintained.

  Further, as described above, when the pair of left and right drive rollers 20a and 20b are rotated following the unwinding of the unrolling belt-shaped liner R1, the unloading speed of the rubber-like elastic member W is separated from the rotational driving force. Since it is transmitted to the drive roller 24 of the conveying device 11, the unwinding speed of the rubber-like elastic member W unwound from the unwinding strip liner R1 and the member conveying speed of the member conveying device 11 are synchronized, and the member Can be transported to the next process without being excessively pulled and deformed.

  In this way, the rubber-like elastic member W separated and unwound from the belt-like liner Rx is cut to a predetermined length on the member conveying device 11 provided with the member cutting device 11a, and then the molding machine 12 side. To be supplied.

  As described above, when the belt-like rubber-like elastic member W is peeled off from the belt-like liner Rx and unwound, the left and right sides always rotate in contact with both sides in the width direction of the belt-like liner Rx as the belt-like liner Rx is driven to rotate. Since the rubber-like elastic member W is unwound by the pair of peeling rollers 17 and the surface of the strip-shaped liner Rx disposed coaxially between the peeling rollers 17 and the non-contact free roller 19, the rubber-like elastic member W is unwound. The member W can be reliably separated from the belt-like liner without giving tensile deformation.

  In addition, by selecting an appropriate roller diameter and height suitable for the thickness, rigidity, tack and other characteristics of the belt-like rubber-like elastic member W, a cooperative peeling force can be obtained, and the surface of the belt-like liner Rx No special treatment (fluorine, silicon coating, etc.) is required, and the cost of the strip liner Rx can be reduced.
