The present invention relates to a device for detecting the width of a tape film in the manufacturing process; in particular, it refers to a technology that uses an actuator to drive a sensing unit to provide a data reading module to sense the width of a tape (or the like).

The application of extrusion equipment to supply rubber material, through multiple roller systems and pressure mechanisms, to form a rolled rubber strip or the like is a well-known technique; for example, Taiwan No. 85104915 "For simultaneous rolling and "Device for Stretching Plate Workpiece", Patent Case No. 97114099 "Device for Manufacturing Rubber Strip Material", etc., provide relevant reference materials.

The prior art also discloses the technology of disposing adhesive, release layer and/or printing on this type of tape or the like; for example, Taiwan No. 96141008 "Adhesive Tape and Adhesive Tape Roll", No. 93139205 "Tape Related reference materials are provided in the patent case of "Printing Device and Tape Printing Method".

A subject related to the continuous winding of this type of tape or the like with rollers into a roll is that due to external force factors (for example, the vibration of machinery and equipment, the pressure of the roller winding, etc.) or the working error, the tape will be caused The edges of the roll are not aligned or flat.

As those who are familiar with this technique know, the edges of the finished product of the tape roll are not aligned or flat, which often causes the industry to discard the entire finished product, which leads to an increase in manufacturing costs and time; and this is not our case. Expected.

Typically, these related reference materials show the design skills of the conventional tapes or their analogs in terms of structure and manufacturing; they also reflect some of the problems existing in these tapes or their analogs. If the redesign takes into account the structural manufacturing technology of the tape or the like, making it different from the conventional technology, it will improve its structure and different from the previous technology; in fact, it will also reduce the winding of the tape. Unevenness or misalignment. In addition, the manufacturing cost and time increase due to the discarding of the finished product is minimized as much as possible.

These issues have not been taught or specifically exposed in the above-mentioned related reference materials, and these technical problems need to be solved urgently.

The main purpose of the present invention is to provide a tape film width detection device in the manufacturing process, which includes an actuator, a combination of a sensing unit driven by the actuator, and a data reading module. The data reading module is equipped with a data body and a linkage part, which is connected to the sensing unit; when used as an actuator to drive the sensing unit to move, the linkage part will move synchronously, so that the sensing unit will detect the edge of the tape film , So that the data reading module can record the moving distance of the sensing unit at the same time and send it back to the computer (or Programmable Logic Controller; PLC for short) to calculate the width of the film, and then adjust the process parameters in time to avoid material damage in the process loss.

According to the tape film width detection device in the manufacturing process of the present invention, the data main body of the data reading module is connected to the linkage part; the data main body can be made into a disk or plate shape, and rotates or reciprocates with the movement of the linkage part The effect of movement is to help personnel obtain the range of variation of the tape film (or the like) detected by the sensing unit; for example, the range of variation of the edge of the tape film.

Please refer to Figure 1, which depicts the structure combination of the data reading module, the linkage unit, the sensing unit and the actuator. The tape film width detection device in the manufacturing process of the present invention includes a combination of a data reading module and a sensing unit; they are denoted by reference numbers 10 and 20, respectively. The data reading module 10 includes a data main body 11 and a linkage part 12 connected to the data main body 11; the data main body 11 is arranged and fixed on a base 30.

In the embodiment of the present invention, the data main body 11 is connected to one end of the linkage portion 12, and with the movement (or movement) of the linkage portion 12, it generates data that can record the degree of movement (or movement distance). And, the linkage portion 12 can be a belt-like pulling, tooth adjustment, or linkage structure; and the linkage portion 12 is connected to the sensing unit 20, and the sensing unit 20 is driven by an actuator 40 to move or move.

In detail, the data body 11 of the present invention is made into a movable disk body (or gear, friction wheel structure), and the recording function of the numerical value or similar index disk is considered on the disk body; by means of the disk body (or the data body 11) The range or degree of motion of) is digitized (or generated data), and constitutes a function similar to a numerical value generating device. In addition, the linkage portion 12 forms a belt (or rack) to connect (or engage) the data body 11, so that the data body 11 and the linkage portion 12 form a form that can move synchronously.

In a feasible embodiment of the present invention, when the data main body 11 is equipped with a numerical value decoder, the numerical value decoder can read the data of the movement range or the degree of movement of the data main body 11. And, the data subject 11 can be connected to a computer or a programmable logic controller (ie, Programmable Logic Controller; PLC for short) (not shown in the figure), and the computer or PLC can be provided to obtain the movement value of the data subject 11.

The figure also depicts the structure in which the linkage part 12 is connected to the sensing unit 20 and the sensing unit 20 is connected to the actuator 40.

In the embodiment of the present invention, the sensing unit 20 is arranged on a rod unit 25. The rod unit 25 is connected to the linkage portion 12. And, the actuator 40 is fixedly connected to the rod unit 25.

The figure shows the type of the rod unit 25 passing through a channel 31 of the base 30; therefore, the rod unit 25 can reciprocate along the channel 31 driven by the actuator 40. The actuator 40 is a pneumatic cylinder or a hydraulic cylinder, and a mechanism driven by a motor may also be used; for example, a ball screw, a turbine scroll or a linear motor.

Please refer to Figures 2 and 3, respectively depicting the sensor unit 20 above and below the tape film 50, and on both sides of the tape film 50, respectively, the data reading module 10, the actuator 40 and the sensing unit 20 are arranged to measure The width of the tape film 50 (or the edge area of the tape film 50).

In the actual operation process of the present invention, the sensing units 20 on both sides of the tape film 50 cooperate with the drive of the actuator 40 to form (synchronize) movement in the same direction or in different directions.

When the tape (film) 50 or the like cooperates with the roller 55 to perform conveying and/or winding operations, the sensing unit 20 moves with the drive of the actuator 40 to detect the state of the width of the tape film 50 (or its edge area) And, the actuator 40 also drives the rod body 25, so that the linkage portion 12 cooperates with the movement to drive the data body 11 to produce movement, and the data reading module 10 is provided to sense the state, so as to facilitate the personnel to obtain the sensing unit 20 to detect The data or variation range of the state of the tape film 50.

In other words, in the actual operation process of the present invention, when the conveying operation of the tape film 50 is normal (or the edge of the tape film 50 is flat), the value or the variable value sensed by the data reading module 10 is within the allowable range or the set value; This means that a finished product with a smooth winding will be obtained.

In the actual operation process of the present invention, when the sensing unit 20 detects that the width (or edge area) of the tape film 50 is offset or that the conveying pressure of the roller 55 is changed, the data body 11 is driven to move through the linkage part 12, so that the data is read When the module 10 senses that the variation of the tape film 50 exceeds the allowable range or the set value, the tape film 50 can be adjusted to return to the correct position through shutdown or other modes to improve or reduce the uneven winding of the tape film 50.
