Description of the invention (Field of invention: Please read the precautions on the back before filling out this page. The present invention is a tension adjustment device applied to cymbals. The tension applied to the sheet is based on the feeding of the sheet. The diameter of the paper roll is changed, and the K-scale is adjusted. BACKGROUND OF THE INVENTION: A traditional medicine packaging equipment includes a feeding unit that supports a roll of hot-melt packaging paper sheet by M rotation, M, and The sealing device on the feeding path of the packaging sheet is tiled and fed; upstream of the sealing device, the sheet is covered in a folded state. After the medicine is supplied, the sheet is sealed by the sealing device from the width of the sheet to the edge. Heat-seal to seal the medicine in it. When the packaging sheet is used up, a new paper roll is installed in the feeding unit so that the new sheet can be flattened and fed; when the feeding is fed, the sheet The material needs to be stretched uniformly, and the error in opening the sheet does not affect the sealing position; however, the diameter of the sheet is gradually reduced due to the gradual release of the sheet from the paper roll. The tension is also gradually changing. Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs, Japanese Utility Model Announcement No. 1-368 32, which reveals that a uniform tension can be applied without changing the diameter of the sheet roll. Sheet tension adjusting device. The sheet tension adjusting device has a supporting roll provided with a paper roll, and a plurality of roll diameter detectors provided on the side of the paper roll. The signal is used to control an electromagnetic force. The electromagnetic force of the brake output is gradually reduced as the diameter of the paper roll decreases. The electromagnetic force is provided by an electromagnetic brake provided on a support roll. In this conventional sheet tension adjusting device, The length of the cymbal material on the roll (which changes with the sheet being pulled out) is a straight roll of paper set in the diameter direction of the roll. The size of the paper applies to the Chinese National Standard (CNS) A4 (210X 297 g). 4 494081 Λ7 B7 Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs 5.

Description of the invention (4) The braking force control level; therefore, the paper roll The braking force control obtained by changing the diameter can achieve the optimal adjustment of the M material tension at each step. In this example, each braking force level is reversed from a larger value to one. Please read the precautions on the back first and then the smaller value sheet. The paper force level is sharp; however, the signal is broken. In order to understand the pattern of the cracked device, the reason for the change in the volume of the book is that when the second is sent to the control unit, it is a single state. The review and approval of the control operation is simple. To change the diameter of other intersecting coils, the sensor unit based on the invention is based on the tension of the unit. It needs to be directly curled without the device. (After the sheet, the adjustment of the force of the film will interrupt the securing layer. Because κ is a sense of average, it does not matter whether the length sensor is the signal of the level of the operation of the sheet material, change the problem in the detection diameter of the reactor. Whether the reactor and the fracture are at the same time; The features and objectives of the invention are described in detail with the drawings: The car's application of force will not result in a traditional configuration, and each brake will change to a sharp angle sensor. material * May be determined to exist if the result is a pause or a sheet can have further tension adjustment described later.

Description of the invention (13) Fine-tuning step, the signal is received A sheet length sensor or a rotary encoder 32, and an angle sensor or a hall element sensor 25. In step SS5, the control unit calculates the sheet length of the paper roll according to the information of the foregoing formula to determine whether the paper roll is on the maximum diameter; if it is not possible to perform lotus calculation (N 0), repeat step SS3; when the calculation After completion, the control unit decides whether to meet the conditions for leaving the specific operation mode in step SS7. If so, the tension is adjusted to an appropriate level in step SS8; steps SS9 and SS10 use K to detect the heart tube Slide (follow-up). In the tension adjustment of step SS8, in order to avoid a sudden change in tension, if the paper roll is under the maximum diameter (new paper roll), the corresponding DC voltage of the maximum tension is set at 25 V, and if the paper roll is at half the maximum The DC voltage corresponding to the maximum tension under the diameter is set at 20 V. After the tension is adjusted at an appropriate level, the execution of the program returns to step S0 to determine whether a specific operation mode needs to be executed. If the specific mode is not required at this time, the program and the operation in the normal mode continue [A]. In the normal mode shown in FIG. 10, the manual fine-tuning mode switch is changed first, and the previously set data is read in step S1. At this time (step S2), each sensor is maintained at 0N; at this time The normal mode of the packaging unit is started, and after the start, the tension control is changed according to the appropriate DC current level adjusted in the specific mode. Next, in steps S3, S4, and S5, the sheet length signal and the angle sensing signal are simultaneously input into a specific mode, and K calculates the length of the material. This calculation is performed according to the above formula; if the calculation result is displayed as a new paper When rolling R, the DC voltage is based on the judgments in steps S 6, S 8, S 1 0, and S 1 2 respectively.

After the aforementioned tension control step is completed, the control unit judges whether the cardiac tube has slipped according to the signal of the proximity switch 26 in step S14. As shown in FIG. 5, the proximity switch 26 is set relative to 16 magnetic protrusions, It is used to generate a pulse signal every time the heart tube rotates 22.5 ° (the method is similar to the Hall element angle sensor 25). In the implementation of the present invention, the angle sensors 25 and 26 are different types, but they can also be the same type. The timing chart in FIG. 12 shows the relationship between the angle sensor and the rotation angle pulse signal; as shown in the figure. Unless the condition of the roll paper changes with tension, the pulse signal generated by the slide detection sensor can be obtained in synchronization with the pulse signal generated by the roll paper length detection sensor. However, if the rotation resistance of the motor brake 20 caused by the DC voltage of the upper shaft is abnormal (for example, when the tension level is N = 2, the tension is too great), the paper roll R will be intensely linked with the heart tube P. This Phenomenon can cause the position shift between the magnetic element 17 and the phase-attracting magnet 16; if this happens, although the Hall element sensor 25 still generates signals every 2 2.5 °, the proximity switch 26 may generate two pulses at the same time Signal, and at the next 22.5 ° of the heart tube, no signal can be generated. Figure 12 shows how the pulse signal changes when the position shift occurs. As shown in the figure, when the heart tube completes one revolution, the slide detection sensor cannot generate a pulse signal at positions C and D, but is approaching A pulse signal is generated between positions D and A.

Description of the invention (15) Under this condition The control unit can determine that the slide detection sensor cannot generate a pulse signal at position C by referring to the signal generated by the roll length detection sensor; for example, if the DC current of 16 V is at the level of N = 2 If it is too high, that is, if the tension is too high, the voltage can be reduced to 14V. K adjusts the tension to a suitable level. With voltage adjustment, a pulse signal can be generated at any appropriate position after position D. After adjusting the position deviation of the cardiac tube P caused by the change in tension, the control unit checks whether there is still paper on the cardiac tube P according to the signal of the end sensor 31 in step S16. If the end sensor 31 has not yet When the end of the paper is detected, step S3 is performed, that is, the control of the sheet tension is based on the length of the roll paper obtained by the above calculation method. When the end sensor 31 detects the end of the encapsulating sheet S, the operation of the tension control mode is stopped; if continuous packaging is required, the program will first return to a specific mode to replace the paper roll R and communicate with the end sensor. connection. In the flowchart of the specific mode, steps SS9 and SS10 are indicated by dashed lines, which means that these steps are not essential. If these two steps exist, their functions are similar to steps S 1 4 and Slip detection operation in S 1 5. The above description is based on the assumption that the roll R is full volume; if the roll diameter in the paper feed unit is only one and a half of the above maximum diameter, the adjustment of the specific mode in this example is to adjust its tension slightly higher than In the normal mode of the largest diameter embodiment, when the paper is discharged to half the diameter of the paper roll, the normal mode operation of this embodiment can begin; therefore, it can be stable without sudden changes in tension. Ground starts normal mode.

Description of the invention (17) Cut off, because the sheet tension adjustment device of each embodiment is combined with a drug The packaging device is used, and the sheet fed to the packaging device may be broken due to excessive braking force or the paper roll sheet is exhausted, so the cut-off judgment function is necessary. In the previous embodiment, the feed length is detected by the rotary encoder 32, and based on the detected feed length, the length of the roll paper on the paper roll can be calculated, and then based on the obtained roll paper Length (pulse signal of the angle detection sensor or Hall element sensor 25), you can know the radius of the paper roll and the braking force that should be output; in addition, the sliding of the heart tube P relative to the flange 15 can also be used as The proximity switch 26 of the position shift detection sensor detects it; and the signals of each of the above sensors can also be used to determine whether the sheet is cut or not. The following describes two situations of detecting the cut of the sheet. In the first situation, the sheet is cut between the paper roll R and the rotary encoder 32; in this example, when the rotary encoder 32 generates a length measurement signal of a sheet feed length, the Hall element senses One of the sensor 25 and the position shift detection sensor (proximity switch 26) does not generate a signal. In this example, the control unit 30 may use a new program for determining whether to cut the sheet to determine whether the sheet is cut or not. Based on this determination, the control unit 30 outputs a control signal to the heating roller 6 On the motor 6a, M prevents the operation of the motor 6a, the control unit 30 outputs a control signal to the feeding device that feeds the medicine to the packaging device, and M stops the feeding of the medicine, and the sheet cutting can be performed.

Description of the invention (IS) A roller printed by a motor (not included) (Illustrated), and the rotary encoder 32 is set on the shaft of another driven roller 3, and the motor (not shown) is a synchronous operation of the motor 6a of the heating roller 6, which can also be omitted, and A belt, K motor 6 a drives the feed roller 3. FIG. 13 shows a flowchart of an embodiment of the program with the above-mentioned cut-off function; as shown, steps S17-S19 are inserted between steps S4 and S5 in the flowchart of FIG. 10; in step S17, it is judged Whether the signals from the sheet length sensor and the angle sensor are received, and if the signals are received, step S5 is performed. If the signal is not received (N 0), the time is counted in step S 1 8; if no signal is obtained within a predetermined time, it can be determined that the sheet has been broken, at this time, an error message is displayed, and if necessary Stop the drive source. The signal status of the sensor that has not received the signal is shown in Figure 14. It also shows the signal status of the heart tube P in the second and subsequent rotations. This procedure is also applied to the next example. . In the second state, the sheet material has completely stopped its feeding state. In this example, when the rotation counter 33 in FIG. 3 can count the number of rotations, the three detection sensors (angle detection sensor, position deviation One or any of the sheet feed length detection sensors formed by the motion detection sensor and the collective motion rotary encoder 32) does not generate a signal at all. In this example, one can be used to determine whether to cut or not. The judgment program of the broken sheet is used to determine whether the sheet is cut or not, and the control after the sheet cut determination is the same as that described in the previous example. The rotary encoder 32 can be set on the axis of a feed roller 3 shown in the figure, or on the axis of the motor 6 a of the heating roller 6, and used for the judgment of the above two examples.

The description of the invention (19) The procedures can be exactly the same. If the materials in the above two examples are cut off, when signals are generated from both the rotary encoder 3 2 and the rotary counter 3 3, this judgment program can receive no position deviation detection sensor and angle detection sensor. It is judged that the sheet has been cut by one or any signal of the device, and the control after the sheet cut is determined is the same as that described in the previous example. This embodiment is used in the configuration shown in FIG. 2, in which the magnet 16 and the magnetic element 17 are disposed between the core tube P and the flange 15 of the hollow shaft lc, thereby detecting the difference between the two. This configuration can also be used in another mode, in which the magnet 16 and the magnetic element 17 are integrally formed on the flange 15 or the protrusion of the heart tube P, and K replaces the original magnet fixing device. Therefore, there will be no displacement in the rotation direction between the heart tube P and the flange 15. In this embodiment, since the heart tube P does not have the problem of displacement, the position shift detection sensor is not required. Settings. In this example, the proximity switch 26 can be used as an angle detection sensor. At this time, a sensor including a Hall element sensor 25 or an angle detection sensor is used. In this example, even if the sheet is halfway through It is cut or not fed at all, and there is no signal generated by the angle detection sensor. Therefore, in the state where the rotation counter 3 3 can generate a signal, whether the rotary encoder 3 2 is installed on the shaft of the drum 3 or The fact that the sheet is cut off on the shaft of the motor 6a is determined by a judgment program based on whether or not a signal is generated by the rotary encoder 32.
