Description

  The present invention is a touch of a sheet split winder that divides a wide strip of plastic film, paper, metal foil, etc. into strips of a required width and winds the split strips alternately and vertically. The present invention relates to a roller device.

  In the above-described sheet split winding machine, the rotational driving force of the winding motor is transmitted to the winding core for each of the divided belt-like sheets by a transmission device, so that the winding core is driven at the center with a required winding torque. There are some which take up a strip-shaped sheet around the core. The touch roller device of the sheet split winder includes a touch roller, and the touch roller is an outer peripheral surface of a winding roll formed by winding the belt-shaped sheet around the core during winding of the belt-shaped sheet. And the belt-like sheet is guided to the take-up roll.

  Conventionally, in a touch roller device, in order to adjust the elongation (tension) immediately before winding of the divided belt-like sheets, a touch roller common to each of the divided belt-like sheets can be freely rotated to a fixed position between a pair of frames. The common touch roller can be rotationally driven at a predetermined rotational speed corresponding to the supply speed of the divided strip-like sheet. In the sheet split winder provided with this touch roller device, in order to adjust the contact pressure between the common touch roller and the take-up roll, for each of the divided strip-shaped sheets, a pair of swingable on a pair of bases, respectively. A winding arm is provided, and the winding core is supported at both ends by a pair of winding arms, and a required swinging force can be applied to the winding arm by a fluid cylinder device provided between the winding arm and the base. It is common to do so.

  When the touch roller and the take-up roll are brought into contact with each other, the amount of air accompanying the belt-like sheet being wound on the take-up roll is limited. Thus, the amount of air enclosed between the winding layers of the belt-like sheet forming the winding roll can be adjusted, and the friction coefficient between the winding layers of the belt-like sheet is sealed between the winding layers. Therefore, it is possible to prevent the belt-like sheet from slipping between the winding layers and causing the winding roll to collapse. However, it is necessary to increase the outer diameter of the common touch roller from the viewpoint of mechanical strength. If the outer diameter of the touch roller is large, the contact pressure between the take-up roll and the touch roller decreases, and during the winding There is a case where the amount of air accompanying the belt-like sheet cannot be sufficiently suppressed.

  In view of this, some conventional sheet winding machines include a touch roller device for each of the divided belt-like sheets (see, for example, Japanese Patent Publication No. 63-63451). In this touch roller device, the length of the touch roller can be set according to the width of the divided strip sheet, the outer diameter of the touch roller can be reduced, and the air accompanying the strip sheet being wound is limited. Can enhance the effect.

  However, when the contact pressure between the touch roller and the take-up roll is adjusted by holding the touch roller in a fixed position and adjusting the swinging force of the take-up arm with the fluid pressure cylinder device, the take-up arm is heavy. Since the take-up roll having a large inertia is held and the weight of the take-up arm itself is increased, it is difficult to finely adjust the swinging force of the take-up arm with the fluid pressure cylinder device.

  Therefore, in the conventional touch roller device provided for each of the divided belt-like sheets, the touch roller is supported at both ends by a pair of swing support arms swingably provided on a pair of support bases, and fluid is transferred to the swing support arms. There is one in which a rocking force is applied by a pressure cylinder device (see, for example, the embodiment shown in FIGS. 3 and 4 of Japanese Patent Publication No. 63-63451). In this touch roller device, in order to rotationally drive the touch roller, a line shaft penetrating each support base is rotationally driven by a motor common to each touch roller device, and from this line shaft via a transmission device such as a gear. A rotational driving force is transmitted to the touch roller on the swing support arm.

Japanese Examined Patent Publication 63-63451

  However, in the conventional touch roller device, a rotational driving force is applied to the touch roller supported by a swingable support arm on the support base from a line shaft penetrating the support base via a transmission device such as a gear. Therefore, the rotational driving force transmitted to the touch roller affects the swinging force of the swinging support arm. Therefore, in order to accurately adjust the contact pressure between the touch roller and the take-up roll to the required level, the influence of the rotational driving force of the touch roller on the swinging force of the swing support arm is taken into account. Need to compensate. In addition, in the sheet split winder, the width of the strip-shaped sheet changes variously, and the length of the touch roller changes accordingly. Further, the load of the touch roller also changes depending on the center driving force of the winding roll. Therefore, the relationship between the contact pressure between the touch roller and the take-up roll and the rotational driving force transmitted from the line shaft to the touch roller is very complex, and the rotational driving force transmitted to the touch roller is accurately grasped. In order to do this, it is necessary to measure it momentarily. Therefore, in order to accurately control the contact pressure between the touch roller and the take-up roll, a control device therefor becomes complicated and expensive.

  In addition, since the rotation of the common line shaft is transmitted to the touch roller, simply providing a belt transmission device or a gear transmission device cannot individually adjust the torque transmitted to the touch roller. It is necessary to interpose transmission torque adjusting means such as a powder clutch in the transmission device from the line shaft to the touch roller. However, since the space occupied by the torque adjusting means is large, the touch roller device becomes large in size and often cannot satisfy the winding conditions such as the minimum winding width of the sheet split winder. In addition, when the rotation of the line shaft is transmitted to the touch roller by the gear transmission, it is necessary to cover the transmission device so that gear dust and the like do not adhere to the belt-like sheet. This can cause trouble.

  In view of this, the present invention provides a sheet split winder having a required rotational driving force so that the touch roller supported at both ends by a pair of swing support arms does not affect the contact pressure between the touch roller and the wind roll. It is an object of the present invention to provide a touch roller device that can easily replace the touch roller.

  The present invention includes a touch roller that contacts an outer peripheral surface of a winding roll of a belt-like sheet and guides the belt-like sheet to the winding roll, and can swing around a swing center axis parallel to the touch roller. A pair of swing support arms provided on a support base for supporting the touch roller at both ends, and a swing force on the swing support arm for bringing the touch roller into contact with the take-up roll with a predetermined contact pressure. A touch roller device for a sheet split winding machine, comprising a swinging force applying mechanism for applying, wherein the touch roller includes a body part around which a belt-like sheet is wound, and both ends of the body part fixed to the body part. And a pair of swing support arms each having a holding portion for detachably holding the housing, and a housing that is rotatably mounted on the center support shaft. A pair of swing support arms And at least one of the swing support arms is disposed outside the swing support arm at an interval in the axial direction of the touch roller, and has an auxiliary arm fixed to the swing support arm, and the swing center axis. And a hollow shaft body fixed to the swinging support arm and rotatably mounted on the support base, and a first portion concentrically with the hollow portion of the shaft body. A transmission shaft is provided, a second transmission shaft is provided concentrically with the touch roller on the auxiliary arm, a motor for rotationally driving the first transmission shaft is provided at an inner end of the shaft body, and the first A transmission device for transmitting the rotation of the transmission shaft to the second transmission shaft is provided along the outside of the auxiliary arm, and when the housing is held by the holding portion, the transmission device is moved outward from the one swinging support arm. The end of the central support shaft protruding to the auxiliary arm Characterized in that it comprises a gear shape joint connecting the end of the second transmission shaft which projects into Luo touch roller.

  According to the present invention, the motor for rotationally driving the touch roller is provided at the inner end of the shaft fixed to the swing support arm, and the rotational driving force of the motor is swung from the first transmission shaft. It is transmitted to the second transmission shaft by a transmission device provided along the outer side of the auxiliary arm fixed to the dynamic support arm, and from the second transmission shaft provided to the auxiliary arm to the center support shaft of the touch roller by a gear-type shaft joint. Since transmission is performed, the motor and the transmission system from the motor to the touch roller are all arranged on the same swing support arm. Therefore, the rotational power of the motor does not affect the swinging force of the swinging support arm against the support base, does not affect the contact pressure between the touch roller and the take-up roll, and individually for each touch roller. A required rotational driving force can be applied. Therefore, since the shortage of the center driving force by the winding motor of each winding roll in the sheet split winding machine can be compensated by the surface driving force by the respective touch rollers, a large number of strips are formed on the winding core having a small outer diameter. Even when a sheet is wound to form a winding roll having a large outer diameter, it is possible to form a winding roll with good quality. Even if a motor and a transmission system are installed, the space occupied by the pair of swing support arms hardly increases, and the control of the contact pressure between the touch roller and the take-up roll does not become complicated. Therefore, for example, in an existing sheet split winding machine, a touch roller device including a non-driven touch roller can be easily changed to the touch roller device of the present invention in many cases. Further, when the touch roller is supported at both ends by the pair of swing support arms, the outer end of the center support shaft of the touch roller faces the end of the second transmission shaft on the side of the touch roller. The second transmission shaft can be easily connected to or disconnected from the second transmission shaft. Further, since the rotation of the first transmission shaft is transmitted to the second transmission shaft by the transmission device provided along the outside of the auxiliary arm, this transmission device and the touch roller are not attached or detached, and the touch roller replacement work Becomes easier. Furthermore, it is relatively easy to cover the transmission device with a cover so that the abrasion powder generated in the transmission device is not scattered, and the end of the central drive shaft connected by the gear shaft coupling and the second transmission shaft are connected. Since the end portion is covered with the outer cylinder of the gear-type shaft coupling, even if foreign matter such as wear powder is generated in the transmission system from the motor to the touch roller, scattering of the foreign matter can be sufficiently suppressed. Therefore, the touch roller device according to the present invention is also excellent from the viewpoint of preventing foreign matters from adhering to the belt-like sheet and causing defective products.

  The gear-type shaft coupling is fixed to the inner end portion of the second transmission shaft, fixed to the first inner cylinder with an external gear, and to the end portion of the center support shaft of the touch roller.

It is convenient because it can.
