[Technical field to which the invention belongs] The invention relates to a method for A sheet, such as a photo, document, or chart, is sealed between, for example, a pair of transparent plastic sheets. More specifically, although it is not specific, the present invention is particularly related to a laminator having a mechanism capable of detecting the thickness of a lamination to be sealed, and an adjusting mechanism may be adjusted according to the detected thickness. The laminations are passed by the speed of the heated rollers of the laminator. 10 [Prior Art] BACKGROUND OF THE INVENTION The conventional laminator includes a pair of internal heating rollers, which will spring against each other or be arranged at a fixed interval, and the layers to be sealed by lamination will be in between. Being hot pressed. The heat generated by the rollers will melt the surface of the adhesive on the plastic sheets 15, and the melted mucosa will penetrate into the sheet to be sealed to a certain extent. Cards and tissues will be easier to seal because the preset temperature and speed settings of these rollers can achieve the required adhesion between the layers. However, when, for example, a thicker sheet is to be sealed, the preset temperature and speed settings may cause insufficient adhesive to penetrate into the sheet, making the finished product easy to delaminate and peel. For this reason, the laminated product may need to pass through the machine again, and may even be processed a third time. This will result in a loss of productivity and even damage to the finished product. 't Sun and Moon Dissolve 1] Summary of the invention 1229638 玖, description of the invention The purpose of this invention is to overcome or sufficiently improve the above-mentioned disadvantages, and / or provide a thickness sensor for laminators; and Laminator with thickness sensor and speed-controlled sealing, heating roller. The disclosure of the invention is a thickness sensor for lamination material for entering the laminator, including: 10 an arm can move when interacting with the lamination material; and-the device can be based on the arm's Position to provide a variable resistance output. The device for providing a variable resistance preferably includes an electrical conductor mounted on the arm and forming-the exposed electrical contacts, and-the PCB has exposed trajectories that can be abutted by the electrical contacts, and The resistors and the like are electrically connected to adjacent portions of at least one of the wires. 15 It is preferred that each of these wires include-the ends be electrically isolated from each other. When they are each abutted by one or more of these electrical contacts, it can be shown that the laminate is too thick. It is preferable that the end portion includes an auxiliary portion electrically isolated therefrom, and i can provide a warning signal when the I electrical contact abuts, indicating that the laminate system has a large allowable thickness. Preferably, the arm is pivotally mounted on a pivot lock 'and the trajectory is-a curved-preferably the arm includes a roller at one end that can abut the laminate material, and the pivot pin is closer The roller is further away from the electrical contacts. The present invention also discloses a laminator, which includes ..., and etc., and the roller pair heating roller can press the desired lamination material J it's degree of sensing state in the laminating machine at l 20 1229638 玖, the upstream of the description of the invention, and the speed of one revolution with the laminator. The rotary motor is driven by a rotating motor to change the rollers, and its operation is preferably at least one of the rollers is affected by the thickness sensor. 5 It is preferred that the laminator further comprises a pair of take-up rollers located downstream of the heating rollers. Preferably, the pick-up rollers and the heating rollers rotate in harmony through a gear set in between. Brief description of the drawing 10 The tree is bright—the preferred form will now be explained with reference to the relevant formula; Among them: Figure 1 is a three-dimensional schematic diagram of the thickness sensor of the sheet material; Figure 2 is the thickness sense of the i The three-dimensional schematic diagram of the measuring device viewed from another angle; 15 FIG. 3 is a schematic cross-sectional view of a laminator equipped with the thickness sensors of S1 and 2; and FIG. 4 is a roller that can ensure that the rollers are all rotating The stereo with the recording group is not intended. I: Embodiment 1 20 Detailed description of the preferred embodiment A thickness sensor 10 is shown in Figs. 1 and 2 of the drawings. The Hai sensor 10 includes a housing in which a printed circuit board (PCB) 16 is mounted. The arm 18 is mounted on a pivot pin 17 and a coil spring yellow 24 is wound around the pin. The coil spring 24 will slightly urge the arm 8 to make it 1229638 buckles, the direction of the invention, and the direction not shown in the figure. The one end of the arm will protrude out of the casing and support the bud roller U to bear the downward facing surface of the three laminated sheets to be laminated. The laminated film is usually a transparent plastic film on both sides, and an image to be sealed is sandwiched therebetween. 5 彳 —The idler wheel 12 is provided above the roller η, and _ idler seats 13 are installed at both ends of the roller η. Each idler bearing 13 is retractably protruded downward by an elastic cyan buckle. The coil case 14 is provided with a coil spring 14 therein. The coil spring " will keep the idler in the -set position, but allow the idler to move upwards-if the total height of the laminated material is too high. If this happens, the 10-layer machine will be temporarily shut down due to a mechanism described later. The arm 18 has a conductive bus bar 21 disposed therein. There are two bullets 19 and 20 extending from the bus bar to a position between the arms 18 and 1 > (3:16. A brush can also be attached to the springs 19 and 20 to abut The rails 22 and 23 provided on the ⑽16. Alternatively, the springs can also directly abut the rails 15. As shown in Figure 1, the distance between the pivot pin 17 and the roller ii, etc. It will be much smaller than the distance between the pivot pin 17 and the electrical contacts and the wires 22 and 23. This will ensure that the arm 18 has a small pivoting motion at the end of the roller, which will make the electrical The contact causes an enlarged movement, so a larger 20 PCB design can be used. One of the tracks 22 is continuous, but contains an electrically isolated end 22A. The other wire 23 will be It is divided into a plurality of short sections and sequentially electrically connected to the surface-mounted resistor 4 and the like. Next to the wire end 22A, the other track 23 also includes electrical isolation sections 23A and 23B, etc. 1229638 When the sheet material abuts the roller 11, the arm 18 will pivot about the pivot pin 17 against the spring 24. The contact brushes attached to the springs 19 and 20 will follow The wires 22 and 23 are moved. When the contact is made with an adjacent short section 23, the resistance of the sensor will change. This will provide a nearly 5 continuous variable resistance, which can It is used to control the speed at which the rollers are driven (to be described later). When the arm 18 is aligned at the sections 22A and 23A, a warning signal such as a beep will sound, or a warning light will Light up to show that the material system to be layered & has reached or is very close to the maximum allowable limit. 10. When the right cross of the arm is aligned with the 22A & 23B part of the trajectory, the The cut-off situation is caused because the blocking and blocking phenomenon will inevitably occur. 忒 The thickness sensor 10 is mounted on a layer laminator with a frame 25, and a mounting spring 6 is extended from the frame 25 to pass through. -Eyelet 34 to hold the sensor. The 15-layer machine itself contains a pair of heated feed rollers which contain an elastic roller pressing surface 26-heater 28. At least-these rollers will be powered by an electric Driven by a motor (not shown). There is also a pair of downstream take-up rollers, at least one of which will be driven and The feeding rollers 26 rotate uniformly. There are-pairs of gear sets 32 each provided at the end of the rollers, which can achieve this function: in order to rotate the rollers, an electric motor can be connected to the child. The gear set 32 is either directly connected to its gears or rollers. An auxiliary heater 29 is provided between the feeding rollers and the pick-up rollers. When in use, the sheet to be laminated will be placed on the laminator. Upstream 20 1229638 玖, the description of the invention, may be placed on a tray 33. These sheets will be manually fed into the machine, so that the bottom sheet abuts the roller 1] (. Therefore, the arm 18 It will rotate to a pivot orientation which can show the thickness of the sheets, and produce a proper resistance in the sensor 10. This resistance will be read and transferred to the motor, which will affect the output speed of the sheet such as Luo Hai. The feed rollers will pull the sheets # at a speed suitable for the thickness of the material, and heat will be applied by the heater M to soften the adhesive on the inward surface of the outer plastic layer. The melted adhesive will not At least partially penetrates into the middle layer. The auxiliary heater 29 further heats the sheet that advances toward the take-up roller 30, which will rotate in harmony with the feed roller 10. The take-up roller 3 It also has an elastic surface to hold the sheets together, and then sends them to a distribution tray 31 for collection. It should be understood that corrections apparent to the skilled person are not beyond the scope of the present invention. For example, The arm can also be moved linearly instead of pivoting, and 15 such rollers can also be used to cause spectral rotation by means other than gear sets. Also, instead of and / or in addition to controlling the traction speed, the resistance of the thickness sensor The reading can also be used to control the radon generated by the electric heater.
