Description of the Invention: [Technical Field] The present invention relates to a roller gap measuring system for measuring the radial distance between two leptons and a leveling machine having such a roller gap measuring system and A method for measuring and adjusting the radial distance between a roller. A so-called leveler or wheel press is used in the manufacture of plastic or rubber films. A leveler has a series of rollers or rollers of a series design with plastic or rubber guided therebetween. In order to vary the thickness of the film, at least the distance between the two rolls, i.e., the roll pitch, can be adjusted by, for example, an adjustment shaft. To adjust the roll spacing, a suitable measuring system is required for very accurate positioning. [Prior Art] There are many roll gap measurement systems in the current state of the art, such as laser measurement, eddy current measurement, inductive displacement sensor, line tension sensor, tape measurement, potentiometer or Magnetostrictive sensors, but all of these measurement systems have drawbacks such as inaccuracies, large sizes, or extreme temperature sensitivity. A more common roller gap measurement system uses a potentiometer that mounts a measuring collar on the shaft nut of the adjustment shaft, which displays the distance between the two rollers on one foot. Since the measuring collar has a length (the ruler cannot be directly fixed to the shaft), the flatness error due to the shaft deflection causes a very inaccurate spacing. In addition, due to the gap between the screw and the gap between the screw nut bearings, the shaft will oscillate and the bearing support fixed at the end of the shaft will cause the measurement error to be amplified. SUMMARY OF THE INVENTION It is an object of the present invention to provide a dice gap measurement system that overcomes the deficiencies of known roller gap measurement systems and has extreme measurement accuracy and very small dimensions. This invention is solved by a kind of patent such as the scope of the patent [the item, the secret measurement of the second light 201233978 sub-radial roller _ measuring system. Among them, the roller can change its position by adjusting the pumping, that is, its radial distance from the other roller, and the adjusting shaft has a shaft nut as a 7L piece. In addition, the roller gap measuring system has a rotation sensor, a 'rib side _, and a cap rotation. The invention also adopts the roller gap 1 week whole system described in the patent scope of the patent application, and the leveling machine described in the seventh paragraph of the patent application scope, and the patent applicant Fan Park first person and the ninth item The method described is solved, and other advantageous derivative designs are described in the respective sub-items. The basic idea of the present invention is to use the lead as a constant lead and measure the amount of rotation of the shaft nut. The distance between the rollers is obtained. In a very advantageous < design, the shaft nut and the rotary sensor are connected to each other by a belt, in particular a window belt, where the shaft nut and the rotary sensor are The transfer has a pulley, especially a pulley, on which the belt is placed, so that the rotary motion is transmitted to the rotary controller by the belt. The pulley connection has a special advantage, so that the rotary sensor can be designed with The shaft nut is separated, so that it can be designed to save space. 11 In the extremely advantageous design towel, the rotation sensing H is designed as a helix encoder. For example, the shaft snail can be accurately measured with a multi-turn absolute rotary encoder. The angle of rotation of the cap, this multi-turn absolute turn The encoder can measure the amount of rotation greater than the circle. In addition, the advantage of the multi-turn absolute rotary encoder is that the measured value can be maintained even if the input current is interrupted. Another very advantageous design, the sense of rotation The measuring device is connected to a processing unit, and the processing unit determines the distance between the two rollers by the amount of rotation measured by the rotating sensor. The stroke of the shaft nut, that is, the distance between the two rollers, is not directly measured, but is instead The rotation angle of the shaft nut is calculated, and the processing unit determines that the second roller pre-pitch is preferably output by an output unit. A roller gap adjustment system for measuring the radial distance between the two rollers, except

In addition, the roller gap measuring system has an input unit for inputting the desired roller gap setting value, so that theleon gap can be feedback controlled by this set value. The roller gap measuring system according to the invention is preferably used in a leveling machine, in particular a calender or a planetary calender, which has at least two lepton capable of changing the gap for plastic or rubber The formation of rails. The number of rollers of the leveler can of course be greater than two.

The one (10) is used as an adjustment element, that is, fresh; 1 <Axis duty 12G. The shaft nut 110 is turned out of the shaft nut 12. Or turn into the shaft nut 12. . At =. = protruding from the end of the shaft, designed with a shaft at the shaft 兀仵 110 "the axial spacing of the two of the towel - the roller clock 112 is not shown to be changed - the first gear m, the two have no relative rotation, =. The first gear can also be designed such that the roller gap measurement system of the embodiment of the invention is additionally included in the front of the cap 12° with the rotating shaft of the tilting shaft nut 120 and the first gear 201233978. Here, the second gear 132 is fixed to the rotary encoder 14〇, and the two are not rotated. The rotary encoder rotates (4) the rotation axis of the second gear is the same axis. The first gear and the second gear 132 are located on the same plane, and are connected by a belt 134, so that the rotational motion of the gear #13G is transmitted to the third gear 132. In this manner, the nut 120 and the first gear 130. The second gear 132 and the rotary encoder 14 are both rotated at the same speed to rotate the amount of rotation of the n 14G side to the stomach 12G. The adjustment shaft 100 is designed between the two light strokes of the pitch to be changed, so that the shaft occupant is deep into the fixed roller bearing housing, and the other end of the adjustment shaft i (8) is located in the position of the roller bearing housing. The roller bearing housing has no contact with any rotating portion. The adjustment shaft 100, in particular the shaft nut (10), has a threaded head that cannot be rotated, which is located in the roller bearing rainbow. The crankshaft can also be designed in the opposite direction between the two turns. Figure 1 additionally shows a processing unit 丨5〇 connected to the rotary encoder 丨4〇. The rotary encoder 140 transmits the measured rotation amount to the processing unit 15A, and calculates the stroke of the shaft nut 120 according to the rotation I, which is the displacement of the shaft member 11〇 from the shaft nut 120. The amount, that is, the roller gap value, the distance between the two rollers, based on a zero position. When the reference zero position is defined as zero gap (e.g., when the shaft member 11 is fully rotated into the shaft nut 120), the stroke is equal to the roller gap value. The stroke can be calculated from the amount of rotation measured by the rotary encoder. The resolution of the rotary encoder per revolution, the reduction ratio of the pulley, and the pitch of the shaft nut must be known. If a rotary encoder with a resolution of 8192 steps per revolution is used, the driven/active diameter ratio of the pulley is 2) 0/72, the pitch of the shaft nut is 5 mm per revolution, and the stroke can be calculated (5 mm / 8192) x ( 2〇/72) The rotary encoder is approximately 0.1695 μm per step, and the roller gap 5 〇 μηη is approximately equal to 295 steps of the rotary encoder. 201233978 unit ^ = two material element 15Q (four) connected to the ridge element (5) and input tilt, 150 the calculated roll gap is transmitted to the output unit 152, sent by the sub = value I can input the desired view by the input unit 154 * ...depreciation 'processing unit 70150 calculates the required shaft nut 120 rotation amount / nut 12 〇 is adjusted by the driver 122 to drive: = 峨 120 rotation amount, by processing a single two drive _ whole drive _ and __ , the roller gap, small can be self-wired (4), the adjustment drive continues until the setting is reached. In the embodiment, the output unit and/or the input unit can be integrated into the processing unit = crying f early 1, the input unit and/or the processing unit can also be integrated into the shaft nut adjustment drive t control ^ such as 'input unit can be off Control panel of the control unit. The early detection, the output unit and the input unit are optional components. In another embodiment, the lepton 1« or the measurement of the nut of the calculation nut can be manual or manual manual. The transfer unit, the output unit and the input unit or some of these units. In the other embodiment, the rotary encoder is not used with the shaft nut connected to the toothed belt, and the reading encoder is used, which directly converts the amount of rotation of the shaft nut by the amount of rotation. The advantage of the code n is that the measurement accuracy is better because the reduction gear is not required, and the disadvantage is that a large space is required because the hollow rotary encoder must be directly mounted on the shaft nut. Compared with the prior art, the invention can have higher accuracy, and the external interference, such as temperature change, the roller gap measurement is almost completely unaffected. In addition, the invention can be placed in the existing space of the leveling. @,@This is also very portable & installed on existing equipment.
