Abstract

PURPOSE:To allow efficient winding by controlling the rotating speed of a control motor based on the calculation results of an adding/subtracting counter and controlling the traverse width based on pulses from the rotary transducer of the control motor. CONSTITUTION:Pulses of a rotary transducer 117 interlocked with a winding motor 116 are frequency-divided by a frequency dividing counter 109. These frequency-divided pulses and pulses from the rotary transducer 108 of a ball screw rotation control motor 107 mounted with a winding pipe are sent to an adding/subtracting counter 104 for calculating therein. The rotating speed of the control motor 107 is controlled based on this variation, and the traverse width is controlled based on pulses from the rotary transducer 108. As a result, the traverse width, lap, width, etc. can be freely set without replacing the equipment.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for winding up a long tape or linear body.

[Prior art]

BACKGROUND ART Conventionally, adhesive tapes used at home and the like have been wound around 20 to 50 tapes onto a paper tube and cut to a predetermined width. In addition, the carrier tape that continuously supplies electronic components etc. to the assembly position is 501 mm wide and about 111 mm wide.
111-It is necessary to wind it to a length longer than 111-h, but
When the adhesive tape is rolled up one after the other in the same way as adhesive tape used at home, the diameter becomes large, and the tape width is particularly small, causing the shape to collapse, which is undesirable. Similarly, a traverse winding method is adopted. In addition, there has recently been a demand for carrier tapes of 500[1- to Ail 11 n-, and it is expected that the required t# of medium IQ and lengths of 0110- or so will be available in the near future.

Furthermore, there has recently been a demand for long tapes or linear bodies that are commonly used, and when winding them up, if the winding width is small, the diameter becomes large, causing various troubles.

Then, it is necessary to adjust the traverse width during winding according to the length of the tape or filament so that the diameter of the wound tape or filament does not become too large.

Next, a conventional tape winding method will be explained based on the drawings.

Figures 7 to 9 are diagrams showing an example of a conventional winding machine, in which Figure 7 is a schematic plan view, Figure 8 is a schematic side view, and Figure 9 is a diagram showing the tape winding situation. FIG.

First, explanation will be given based on FIGS. 7 and 8.

When the tape 19 is traversely wound onto a paper sheet set on the winding shaft 6, the rotation of the pulley 2 is transmitted to the pulley 4 via the belt 3 by the winding motor 1, and the pulley 4 is rotated. When the winding shaft 6 is rotated, the pulley 5 on the same axis is also rotated, and the boot 9-9 on the intermediate transmission shaft 8 is rotated by the timing belt 7.
Rotate the coaxial transmission gear 10 (for adjusting the lap width),
At the same time, the rotation is transmitted to the transmission gear 12 (for adjusting the wrap width),
The pulley 13 on the same axis of the intermediate transmission shaft 11 is rotated, and the scroll camshaft 16 (
) Upper pulley 15 to determine the wrap width during the rubber
By rotating the scroll camshaft 16, the cam follower 1 with the guide roll 18 attached is moved along the cam groove formed in the υ scroll camshaft 16.
By reciprocating the tape 7 from side to side, the tape 19 passes through the touch roll 21 and is wound into a paper tube 20 in a wrapper shape.

Next, a method of changing the traverse width a and the wrap width C shown in FIG. 9 and adjustment of the winding hardness will be explained. The mark indicates the width of the tape.

When widening or narrowing the traverse width a shown in FIG. 9, the scroll cam 16 must be replaced.
It takes time to replace the scroll cams, and it is also necessary to prepare the necessary number of replacement scroll cams as spares.

In addition, when changing the wrap width C (the overlap width with the previously wound tape), the gear 10 of the intermediate transmission 4 shaft 8 and the transmission gear 12 of the intermediate transmission shaft 11 shown in FIG. It is necessary to stop and replace the scroll cam 16 and change the rotation speed of the scroll cam 16 so that the wrap width C becomes a predetermined width, and it is necessary to prepare a spare gear.

By changing the gear as described above, scroll cam 1
When the number of revolutions 6 is increased, the reciprocating speed of the cam follower 17 becomes faster, and the reciprocating speed of the guide roll also becomes faster, so that the wrap width becomes narrower.

Next, when adjusting the winding hardness, adjust the voltage of the tension control torque motor (not shown) in front of the guide roll 18 shown in FIG. Adjustment is made by changing the force of the spring 22 so as to press it strongly.

Above, we have explained how to wind tape by moving the guide roll back and forth, but when winding a linear object such as thread, the method is to fix the guide roll and move the winding tube back and forth to wind it. is also being carried out.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for winding a tape or a linear body, which allows the traverse width, wrap width, etc. to be freely adjusted without changing equipment.

[Structure of the invention]

The present invention is a method for winding a long tape or a linear body by a traverse winding method, in which a pulse of a rotating transducer linked to a winding motor is frequency-divided, and the frequency-divided pulse and a guide roll are Alternatively, the pulses from the rotation transducer of the ball screw rotation control motor on which the winding tube is mounted are transmitted to the addition/subtraction counter, calculations are performed in the counter, and the control motor is rotated based on the deviation value. This is a method for winding a tape or a linear body into a traverse winding method, which is characterized by controlling the number of windings and the traverse width based on pulses from a rotation transducer of a control motor.

Next, the outline of the method of the present invention using a servo motor as a control motor will be described based on FIG. 1. Upper VC set paper W1
23, a tape 124, which is guided and supplied by a guide roll 126 that moves left and right as the rotation direction changes on a ball screw 125 whose rotation direction changes as the servo motor 107 rotates forward and reverse, is used as a sewing thread. It is wound using a similar traverse winding method. That is, the guide roll 126 is attached to a ball screw 125 that rotates, for example, 10.71 times, and each time the servo motor 107 makes one revolution, the guide roll moves 10 times to the left or right as the servo motor rotates forward or backward. Move by step. Winding motor 116 and servo motor 1070 rotating transducers 117 and 108
is a basic operation using 100n pulse 71 rotations,
The frequency of the pulse generated by the rotating transducer 117 is divided by the frequency division counter, and the calculation with the pulse of the servo motor 1070 and the rotating transducer 108 is performed by the addition/subtraction counter 10.
By transmitting the deviation to D-A105 and servo amplifier 1[+6, servo motor 1070
Control rotation.

For example, if the frequency division in the frequency division counter 1Q9 is set to 1/2, when the winding motor 1160 rotation transducer 117 rotates once, 50n pulses are sent to the addition/subtraction counter through the frequency division counter 109, and the counter Inside, calculations are performed with the pulses sent from the rotation transducer 10B of the servo motor 107, and at the same time, a deviation signal is output from the addition/subtraction counter. Based on this deviation signal, the servo motor [7 rotates half a rotation, and the addition/subtraction counter
As the subtraction counter K s n n pulse is sent, the guide roll 126 moves five times, and the tape width becomes 1101.
For tape II, it is a half wrap.

Since the division ratio is proportional to the amount of wrap and inversely proportional to the width of the wrap, the frequency division ratio is set in the frequency division counter through the digital wrap amount changeover switch with this point in mind.

The traverse width (winding width of the tape) is set in a subtraction counter 102, and the pulse signal from the servo motor 1070 rotation transducer is set in the subtraction counter 102.
When the value becomes 0, the number of windings at the winding end is controlled, and the circuit is switched so that the ball screw 126 is reversed to wind the tape in the opposite direction. conduct.

In the example shown in FIG. 1, the transducer 117 of the winding motor is attached to the winding shaft, but it may be directly attached to the winding motor.

Next, the invention will be explained in further detail based on FIG.

The value of the first wrap width setting digital switch 101 is set in the subtraction counter 102, and the value of the wrap amount changeover switch 120 (also t1121) is passed through the digital switch changeover 11n to the frequency division counter fn? Set to . When the value of the setting switch 101 during traverse is set in the subtraction counter 102, first the forward/reverse switching circuit 1
19 is set to normal rotation.

Note that the traverse width setting digital switch 101 can be replaced with a program traverse width setting device, and the ratchet lid setting digital switches 120 and 121 can be replaced with one program lap width setting device.

Then, when the start button of the winding motor 116 is turned on, the winding motor 116 starts rotating, and following this rotation, the servo motor 1n7 starts rotating. When the take-up motor starts to drive, the tape take-up shaft starts to rotate and the tape starts to be wound onto the paper tube set on the take-up shaft.At the same time, the tape guide roll is rotated by the bolt screw rotated by the servo motor 1n7. moves left and right in the middle of the traverse and winds the tape onto the paper tube in a traverse pattern. When the take-up motor 116 starts rotating, the pulse from the rotating transducer 117 linked to the motor is divided into a value preset in the frequency division counter 109, and this divided pulse passes through the gate 111. The signal is transmitted from the forward/reverse switching circuit 119 to the addition/subtraction counter 104, and the counter is incremented. When this addition or subtraction occurs, a deviation occurs in the addition/subtraction counter, and the deviation value is D-
A1n5 converts it into an analog signal, and this signal is
It is transmitted to the servo amplifier, and based on this No. 4g, the servo motor starts rotating in the direction of subtracting the addition/subtraction counter. When the servo motor starts rotating, a pulse from the rotation transducer 108 linked to the servo motor 107 is also transmitted to the ju calculation/subtraction counter 104 via the forward/reverse discriminator 118 and the forward/reverse switching circuit 119, and the counter is subtracted. After the motor starts moving, the deviation value obtained as a result of calculation in this addition/subtraction counter is
A (digital-to-analog converter) 105 converts it into an analog signal according to the deviation value 1, and the analog signal according to the W difference value is applied to the servo amplifier 106, and the ball screw 125 (No. The rotation speed of the servo motor 107 that rotates the servo motor 107 (see Figure 1) is set to a predetermined value, that is, the frequency division value of the frequency division counter is 1! - (value for half-wrap), the rotation speed of the servo motor 107 is controlled so that the guide roll moves by the width of the tape while the take-up shaft rotates twice.

On the other hand, the pulse generated by the rotation transducer 1n8 linked to the traverse servo motor 107 is transmitted to the subtraction counter 102, and the subtraction counter 102 performs subtraction, so that the traverse width setting value set in advance in the subtraction counter becomes 0. When this happens, the traverse of the tape guide roll in one direction ends. When this value becomes 0, a signal from the zero detector 103 closes the gate 111 and stops the servo motor 107, and the zero detector circuit sets the amount of stopping at both ends (the number of times the tape is wound at the end of the traverse width). The value of the digital switch 115 is set in the subtraction counter 115, the gate 112 is turned on at the same time, the pulse of the rotary transducer 117 linked to the winding motor 116 is transmitted to the subtraction counter 113, and the value of the both-end stop F mouse setting digital switch 115 is set. Subtraction is performed until the set value becomes 0. When this value becomes 0, it is detected by the zero detection circuit 114, and the traverse 11 setting digital switch 101 is actuated by the 0 signal, and the value is subtracted from the counter 102. Set to .

This zero stand detector 1n5 detects that the subtraction counter 102 is set to traverse, and in response to the signal, the gate 1t14 is opened, the gate 112 is closed, and the forward/reverse switching circuit 119 is switched. t, the reverse rotation begins, and the ball screw also begins to reverse, causing the guide roll to move in the opposite direction!・Start playing rubber.

When the servo motor starts to rotate in the opposite direction, the rotational speed is changed to the open side, as described above.

Since this I15 light is configured as described above, the wrap width can be easily changed during traverse by changing the setting value of the traverse width setting digital switch and by changing the wrap width of the wrap changeover digital switch. Furthermore, by changing the setting value of the both-end cooling winding setting digital switch, it is possible to easily change the number of tape windings at the traverse end.

In addition, by preparing a digital switch with a number of different traverse + 11 settings during traverse, it is possible to change the traverse as desired depending on the tape winding length, and one traverse width setting switch can have multiple settings. By setting the traverse in advance and sequentially switching from wide to narrow traverse, the traverse in the area near the wound core is wide, and the traverse becomes narrower toward the periphery. As in, i.e.
It is also possible to wind up the core in a trapezoidal cross-section in the longitudinal direction, as shown in FIG. Using the traverse width setting digital switch, set the traverse width so that one end of the traverse width is vertical and the other end becomes narrower as it goes toward the periphery. It is also possible to wind the end face into a conical shape as shown in Fig. 4 by setting the traverse width and position to be different from each other so that the traverse position is shifted with the same traverse width.
By setting the width setting digital switch, it is also possible to wind the roll so that the cross section has the winding shape shown in FIG.

Next, based on FIG. 6, a method of winding the tape in a traverse manner by placing the winding part on the ball screw and reciprocating the winding part from side to side will be explained.

A ball screw 206 is rotatably provided on the base 2nn and rotates forward and backward by a servo motor 208, and a guide bed 20 is attached to the ball screw so as to move left and right as the ball screw rotates.
7 is placed, a winding shaft rotated by a winding motor 205 is provided on the guide bed, and the winding tube 2 inserted onto the winding shaft is placed on the guide bed.
The tape 201 is wound onto 02 in a traverse manner.

In this case, the guide roll 203 may be fixed on a base using a support 204.

Although the rotating transducer and the like are all omitted in FIG. 6, the control method is exactly the same as that described with respect to FIGS. 1 and 2.

When using the method shown in FIG. 6, since the guide roll is not reciprocated left and right, the guide roll and the guide roll 2
5 (see FIG. 8), the overall device can be made more compact, especially when winding a wide tape.

Although the case where a servo motor is used as the control motor has been described, it is also possible to use a DC motor, a pulse motor, etc. in addition to the servo motor.

Although the winding of tape has been described above, the method of the present invention can also be used for winding linear objects such as threads, strings, and electric wires.

In other words, since there is no wrapping when winding a wire, the wrap amount setting digital switch is set so that the moving speed of the guide roll or winding tube is the same as the diameter of the wire per one rotation of the winding tube. Just set it. In addition, by setting the value of the wrap amount setting digital switch so that the moving speed of the guide roll or take-up tube is greater than or equal to the diameter of the wire per one rotation of the take-up tube, it is possible to It is possible to wind in a twill pattern, and by setting the width setting value of the width setting digital switch to be wider near the core and narrower toward the periphery, or One end is vertical, and the other end is set so that the traverse width becomes narrower as it gets closer to the periphery. It is also possible to wind the torano(-su) like this.

The method of the present invention enables efficient traverse winding of tapes, adhesive tapes, threads, synthetic resin filaments, electric wires, and various other linear objects.
