Description

[Technical field]

[0001] The present invention relates to a winding device for a long tape. [Background technology]

[0002] A known device for winding a long tape using a traverse winding method is described in Patent Document 1, for example. In this winding device, the rotation of a winding motor is transmitted to a winding shaft via a pulley, and the tape is supplied onto a paper tube set on the winding shaft, guided by a guide roll that moves back and forth as the direction of rotation changes on a ball screw that changes direction in response to the forward and reverse rotation of a servo motor, and is wound up using a traverse winding method similar to that used for sewing thread.

[0003] The rotary transducers of the winding motor and servo motor operate on a basic basis, utilizing 1000 pulses per revolution. The pulses generated by the rotary transducer are divided by a frequency division counter, and an addition / subtraction counter calculates this with the pulses from the rotary transducer of the servo motor. The deviation is then transmitted to the DA and servo amplifier to control the rotation of the servo motor.

[0004] In addition, in this winding device, the traverse width and wrap width can be easily switched by changing the setting value of the traverse width setting digital switch and by switching the wrap amount switching digital switch to another wrap amount switching digital switch.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 60-218249 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the configuration of the above winding device is very complicated, and the winding device is expensive. Therefore, the object of the present invention is to provide a winding device for a long tape that can wind the long tape by the traverse winding method with a simple configuration according to the tape width and traverse width of the long tape. [Means for solving the problem]

[0007] The winding device of the present invention is a winding device that traversely winds a long tape onto a winding drum set on a winding shaft, and includes a winding motor that rotates the winding shaft, a tape guide that guides the long tape to the winding drum, the tape guide moving left and right on a ball screw provided parallel to the winding shaft depending on the direction of rotation of the ball screw, a sensor that detects the switching position of the left and right moving direction of the tape guide, the sensor being movable along a guide rail provided parallel to the winding shaft, a speed control gear that is replaceably provided coaxially with the ball screw and for adjusting the moving speed of the tape guide, a rotation direction switching unit that transmits the rotation of the winding shaft to the first intermediate gear in a forward or reverse state depending on the detection result of the sensor, and a second intermediate gear that meshes with the first intermediate gear and the speed control gear and transmits the rotation of the first intermediate gear to the speed control gear, the second intermediate gear being supported so as to be separable from the speed control gear.

[0008] According to the winding device of the present invention, the second intermediate gear is separated from the speed control gear, and the speed control gear arranged replaceably on the same axis as the ball screw is set to a speed control gear corresponding to the tape width of the long tape to be traverse-wound onto the winding drum, and a sensor that detects the changeover position of the left and right movement direction of the tape guide is moved along a guide rail arranged parallel to the winding shaft according to the traverse width, so that the speed control gear adjusts the movement speed of the tape guide according to the tape width of the long tape and the long tape is traverse-wound onto the winding drum, and when the tape guide reaches the changeover position of the left and right movement direction, the rotation of the winding shaft is transmitted to the first intermediate gear in a forward or reverse state, and is further transmitted to the speed control gear via the second intermediate gear, thereby changing the left and right movement direction of the tape guide.

[0009] The second intermediate gear is desirably supported by a support arm that is supported coaxially with the first intermediate gear so as to be able to swing, and is biased toward the speed governing gear. Thus, after the second intermediate gear supported by the support arm is separated against the biasing force to replace the speed governing gear, when the separating force is released, the second intermediate gear automatically returns toward the speed governing gear.

[0010] In addition, it is preferable that the rotation direction switching unit has a drive gear provided coaxially with the winding shaft, a forward rotation mechanism including one rotating body that is pressed between the drive gear and the first intermediate gear and transmits the rotation of the drive gear to the first intermediate gear in a forward rotation state, and a reverse rotation mechanism including two rotating bodies that are pressed between the drive gear and the first intermediate gear and transmit the rotation of the drive gear to the first intermediate gear in a reverse rotation state. In this way, the rotation of the winding shaft can be transmitted to the first intermediate gear in a forward rotation state or a reverse rotation state simply by pressing either one of the rotating bodies of the forward rotation mechanism or the two rotating bodies of the reverse rotation mechanism between the drive gear and the first intermediate gear. Effect of the Invention

[0011] (1) According to the winding device of the present invention, a speed control gear corresponding to the tape width of the long tape is prepared, and a sensor that detects the switching position of the left and right movement direction of the tape guide is moved along the guide rail according to the traverse width. This simple configuration makes it possible to wind the long tape using a traverse winding method according to the tape width and traverse width.

[0012] (2) Since the second intermediate gear is supported by a support arm that is supported coaxially with the first intermediate gear and capable of swinging, and is biased toward the governor gear, after the governor gear is replaced, the second intermediate gear automatically returns toward the governor gear, making the replacement work easier.

[0013] (3) The rotation direction switching unit has a drive gear arranged coaxially with the winding shaft, a forward rotation mechanism including one rotating body pressed between the drive gear and the first intermediate gear and transmitting the rotation of the drive gear to the first intermediate gear in a forward rotation state, and a reverse rotation mechanism including two rotating bodies pressed between the drive gear and the first intermediate gear and transmitting the rotation of the drive gear to the first intermediate gear in a reverse rotation state, so that the rotation of the winding shaft can be transmitted to the first intermediate gear in a forward or reverse rotation state with a simple configuration.

[Diagram 3] 2 is an explanatory diagram of the operation of the drive mechanism in FIG. 1. [Figure 4] 2 is an explanatory diagram of the operation of the drive mechanism in FIG. 1. [Diagram 5] 2 is an explanatory diagram of the operation of the drive mechanism in FIG. 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] FIG. 1 is a schematic plan view of a long tape winding device in an embodiment of the present invention, and FIG. 2 is a schematic configuration diagram of a drive mechanism of FIG.

[0016] In Figure 1, a long tape winding device 1 in an embodiment of the present invention comprises a winding shaft 3 on which a winding drum 2 that winds up the long tape is set, a ball screw 4 arranged parallel to the winding shaft 3, a tape guide 5 that guides the long tape to the winding drum 2, and a drive mechanism 6 that drives the winding shaft 3 and the ball screw 4.

[0017] The ball screw 4 converts the rotational motion of the screw shaft 4A into the linear motion of the moving body 4B. The tape guide 5 is fixed to the moving body 4B and is supported slidably on a guide rail 7 provided in parallel to the ball screw 4. In other words, the tape guide 5 moves left and right (parallel to the winding shaft 3) on the ball screw 4 according to the rotational direction of the screw shaft 4A.

[0018] The winding device 1 also includes sensors 8A and 8B that detect the switching position of the left and right movement direction of the tape guide 5 in order to limit the movement range of the tape guide 5. For example, a proximity sensor that detects the proximity of the tape guide 5 can be used as the sensors 8A and 8B. The sensors 8A and 8B are movable along a guide rail 9 that is provided in parallel with the winding shaft 3. The sensors 8A and 8B are moved on the guide rail 9 in accordance with the width of the winding drum 2, and their positions are set.

[0019] The drive mechanism 6 includes a winding motor 10 that rotates the winding shaft 3, a rotation direction changeover unit 11 that converts the rotation of the winding shaft 3 to a forward or reverse state and transmits it, a first intermediate gear 12 that transmits the rotation of the winding shaft 3 converted by the rotation direction changeover unit 11, a second intermediate gear 13 that transmits the rotation of the first intermediate gear 12, and a speed control gear 14 that adjusts the rotational speed of the ball screw 4.

[0020] The second intermediate gear 13 meshes with the first intermediate gear 12 and the speed governing gear 14, and transmits the rotation of the first intermediate gear 12 to the speed governing gear 14. The second intermediate gear 13 is supported by a support arm 13A that is supported coaxially with the first intermediate gear 12 so as to be able to swing, and is capable of being separated from the speed governing gear 14. In addition, the second intermediate gear 13 is urged toward the speed governing gear 14 by a spring 13B.

[0021] The speed control gear 14 adjusts the moving speed of the tape guide 5 so that the long tape is appropriately traverse-wound onto the take-up drum 2. The speed control gear 14 has a number of teeth adjusted to provide a gear ratio whereby the tape guide 5 moves by the tape width of the long tape during one rotation of the take-up drum 2 (take-up shaft 3). Speed ​​control gears 14 with different numbers of teeth are prepared in advance according to the tape width of the long tape. The speed control gear 14 is replaceably mounted coaxially with the ball screw 4, and is replaced according to the tape width.

[0022] The rotation direction switching unit 11 has a drive gear 15 arranged coaxially with the winding shaft 3, a forward rotation mechanism 20 that transmits the rotation of the drive gear 15 to the first intermediate gear 12 in a forward rotation state (rotating in the same direction), and a reversal mechanism 30 that transmits the rotation of the drive gear 15 to the first intermediate gear 12 in a reverse rotation state (rotating in the opposite direction).

[0023] The forward rotation mechanism 20 has one rotating body 21, a support part 22 that rotatably supports the rotating body 21, and an actuator 23 that moves the support part 22. The actuator 23 moves the support part 22 to press the rotating body 21 between the drive gear 15 and the first intermediate gear 12, or to separate the rotating body 21 from between the drive gear 15 and the first intermediate gear 12. The actuator 23 is, for example, an air cylinder.

[0024] The rotor 21 is a resin roller. The rotor 21 is pressed between the drive gear 15 and the first intermediate gear 12 by an actuator 23, and transmits the rotation of the drive gear 15 to the first intermediate gear 12 in a forward rotation state by frictional force.

[0025] The reversing mechanism 30 has two rotating bodies 31A, 31B, a support part 32 that rotatably supports the rotating bodies 31A, 31B, and an actuator 33 that moves the support part 32. The actuator 33 moves the support part 32 to press the rotating bodies 31A, 31B between the drive gear 15 and the first intermediate gear 12, or to separate the rotating bodies 31A, 31B from between the drive gear 15 and the first intermediate gear 12. The actuator 33 is, for example, an air cylinder.

[0026] The rotating bodies 31A and 31B are resin rollers. The support part 32 supports the rotating bodies 31A and 31B in a state of being in contact with each other. The rotating bodies 31A and 31B are pressed between the drive gear 15 and the first intermediate gear 12 by the actuator 33, and thus the rotation of the drive gear 15 is transmitted to the first intermediate gear 12 by frictional force. At this time, the rotating body 31A contacts the drive gear 15, and the rotating body 31B contacts the first intermediate gear 12.

[0027] Next, the operation of the take-up device having the above configuration will be described with reference to FIGS. 3 to 5.

[0028] First, as described above, the speed-regulating gear 14 uses one whose number of teeth is adjusted according to the tape width of the long tape. Then, the sensors 8A and 8B (see FIG. 1) for detecting the switching positions in the left and right moving directions of the tape guide 5 are moved along the guide rail 9 in accordance with the width of the take-up drum 2. The moving distance of the tape guide 5 moving between the sensors 8A and 8B becomes the traverse width.

[0029] As shown in FIG. 3, when the support part 22 is moved closer to the drive gear 15 and the first intermediate gear 12 by the actuator 23 of the forward rotation mechanism 20 by a control part (not shown), and the rotating body 21 is pressed between the drive gear 15 and the first intermediate gear 12, and the support part 32 is moved away from the drive gear 15 and the first intermediate gear 12 by the actuator 33 of the reverse rotation mechanism 30, and the rotating bodies 31A and 31B are separated from between the drive gear 15 and the first intermediate gear 12, the rotation of the drive gear 15 is transmitted to the first intermediate gear 12 in a forward rotation state by the rotating body 21.

[0030] Further, the second intermediate gear 13 is biased toward the speed governing gear 14 by a spring 13B, and the rotation transmitted to the first intermediate gear 12 is transmitted in a forward direction to the speed governing gear 14 by the second intermediate gear 13. That is, the rotation of the take-up shaft 3 is transmitted in a forward direction from the drive gear 15, which is provided coaxially with the take-up shaft 3, through the rotor 21, the first intermediate gear 12, and the second intermediate gear 13 to the speed governing gear 14, causing the screw shaft 4A of the ball screw 4, which is coaxial with the speed governing gear 14, to rotate in the same direction.

[0031] As a result, the screw shaft 4A of the ball screw 4 rotates in the same direction in synchronization with the rotation of the take-up drum 2. The rotational motion of the screw shaft 4A is converted into linear motion of the moving body 4B, which moves the tape guide 5 in one direction (for example, from left to right toward the take-up drum 2) along the guide rail 7. At this time, the number of teeth of the speed control gear 14 is adjusted to provide a gear ratio in which the tape guide 5 moves by the tape width of the long tape during one rotation of the take-up drum 2 (take-up shaft 3), so that the long tape is appropriately traverse-wound onto the take-up drum 2.

[0032] Then, when the tape guide 5 reaches a switching position of the moving direction, for example, when it reaches the right end position toward the take-up drum 2, it is detected by the sensor 8B. When the tape guide 5 is detected by the sensor 8B, as shown in Fig. 4, a control unit (not shown) causes the actuator 23 of the normal rotation mechanism 20 to move the support portion 22 away from the drive gear 15 and the first intermediate gear 12, to separate the rotor 21 from between the drive gear 15 and the first intermediate gear 12, and causes the actuator 33 of the reversing mechanism 30 to move the support portion 32 toward the drive gear 15 and the first intermediate gear 12, to press the rotors 31A and 31B between the drive gear 15 and the first intermediate gear 12. In this state, the rotation of the drive gear 15 is transmitted to the first intermediate gear 12 in a reversed state by the rotors 31A and 31B.

[0033] Further, the second intermediate gear 13 is biased toward the speed governing gear 14 by a spring 13B, and the rotation transmitted to the first intermediate gear 12 is transmitted to the speed governing gear 14 by the second intermediate gear 13. That is, the rotation of the take-up shaft 3 is transmitted in a reversed state from the drive gear 15 provided coaxially with the take-up shaft 3 to the speed governing gear 14 via the rotors 31A and 31B, the first intermediate gear 12, and the second intermediate gear 13, causing the screw shaft 4A of the ball screw 4, which is coaxial with the speed governing gear 14, to rotate in the opposite direction.

[0034] As a result, the screw shaft 4A of the ball screw 4 rotates in the opposite direction in synchronization with the rotation of the take-up drum 2. The rotational motion of the screw shaft 4A is converted into linear motion of the moving body 4B, which moves the tape guide 5 in the opposite direction (for example, from right to left toward the take-up drum 2) along the guide rail 7. As described above, the speed control gear 14 has a number of teeth adjusted to provide a gear ratio in which the tape guide 5 moves by the tape width of the long tape during one rotation of the take-up drum 2 (take-up shaft 3), so that the long tape is appropriately traverse-wound onto the take-up drum 2.

[0035] When winding a long tape of a different tape width, as shown in Fig. 5, the support arm 13A is lifted against the biasing force of the spring 13B to separate the second intermediate gear 13 from the speed control gear 14. This frees the speed control gear 14, which is then replaced with a speed control gear 14 that corresponds to the width of the long tape to be traverse-wound onto the winding drum 2. After replacing the speed control gear 14, when the force that lifted the support arm 13A is released, the second intermediate gear 13 automatically returns toward the speed control gear 14.

[0036] As described above, according to the winding device 1 of this embodiment, it is possible to wind the long tape using a traverse winding method in accordance with the tape width and traverse width of the long tape with a simple configuration in which the speed control gear 14 is prepared in advance in accordance with the tape width of the long tape and the sensors 8A, 8B which detect the switching position of the left and right movement direction of the tape guide 5 are moved along the guide rail 9 in accordance with the traverse width.

[0037] Furthermore, when replacing the speed governing gear 14, the speed governing gear 14 can be freed by lifting the support arm 13A against the biasing force of the spring 13B, which can be easily performed. After the speed governing gear 14 has been replaced, the second intermediate gear 13 automatically returns toward the speed governing gear 14, making the work easy. [Industrial Applicability]
