Description

The present invention relates to a roll laminator, and more particularly to a technique for coating a paper or the like which is automatically and continuously supplied with a synthetic resin such as polyethylene.

Generally, papers such as documents or photographs that are relatively vulnerable to external pressure (hereinafter referred to as “workpieces”) are stored in an original state for a long period of time without changing to external physical or chemical pressure. It is necessary to coat the surface with a transparent synthetic resin material such as polyethylene. Therefore, many devices for coating a film on the surface of a workpiece have been devised.

A conventional coating machine for bonding a film to a workpiece in this way inserts a workpiece to be coated between a double-layered synthetic resin film prepared in advance, and a heating roller inside a coating machine main body. A pouch method that forms a thin film (heat fusion) by passing through a pressure rotor, and a roll method that mounts a roll film on the upper and lower sides and pushes in the work to form a thin film on the upper and lower surfaces of the work Is done.

However, the pouch method has to be manually inserted between the films manufactured according to the size and form of the workpiece to be coated, so that there is a troublesome work, and the supply of the workpiece and the film is difficult. There is a problem that the coating operation time is increased because the coating operation is not performed continuously.

The roll method, in which only the workpiece is flowed in with the roll-type film mounted inside the coating machine, is coated, and the supply of the workpiece is not performed continuously. There is a problem that the coating operation increases due to the addition of the step of cutting or cutting in the above.

In addition, in order to form a coating film on the workpiece, a roll type film is mounted on the roller inside the main body, and the mounted film is taken out to the outlet through a heating roller and a pressure roller, etc. After adhering to the leading edge of the film, it is required to pass between the heated roller and the pressure roller, which are installed in close contact with each other, and to take it out to the discharge port artificially. There is a problem that is not.

In addition, when forming a coating film on both surfaces of the workpiece while passing the workpiece through a heating roller and a pressure roller, predetermined static electricity is generated and the workpieces are not sequentially loaded on a discharge tray due to static electricity between the workpieces. Laminators also have uneven loading (whether or not the discharge tray is mounted) and the hassle of manually rearranging the coated workpieces.

In addition, since the conventional heating roller has a relatively low thermal conductivity still surface, the time required to reach a specified temperature for forming a coating film is relatively long, thereby increasing the overall process time. Act as a factor.

Therefore, the purpose of the present invention is to install a lid that can be opened and closed by a hinge type, and to install the upper and lower heating rollers and the pressure roller so that they can be separated from each other to facilitate the mounting of the roll film and to continuously supply the workpiece. It is an object of the present invention to provide an automatic roll laminator capable of reducing the processing time.

In order to achieve such an object, the automatic roll laminator of the present invention has a supply port into which a workpiece is inserted and a discharge port through which a coated workpiece is discharged, and a paper feed tray and a discharge tray on the left and right sides. A main body, a front lid and a rear lid, which are hinged to be openable and closable forward and rearward with respect to the main body, respectively, above and behind the main body, and vertically mounted on one side of the supply port. A supply roller for allowing the inserted workpiece to flow into the main body, a film roller that is installed with a roll film attached to one side of the supply roller and pulls out a film on the surface of the workpiece that has flowed in, and the film A heating roller and a pressure roller made of aluminum so that the film is adhered, heated and pressed against the surface of the workpiece by being installed in contact with one side of the drawing roller. And fixed cutters respectively installed on the upper support plate and the lower support plate installed inside the main body so as to cut the laminated workpiece set to one side of the pressure roller into a predetermined size, and And a rotary cutter.

In addition, the present invention provides a microcomputer, a standby roller for moving a workpiece moved from the supply roller to a heating roller side, and a standby roller for sequentially placing a workpiece seated on a supply tray under the control of the microcomputer. An electronic supply clutch that advances, a clutch controller that controls the operation of the supply clutch, a sensor that detects the inflow of a workpiece, a sensor that detects a workpiece passing through the standby roller, and a roll film. A film sensor for detecting whether the film is mounted, a temperature sensor for detecting and maintaining the surface temperature of the heating roller at a constant level, an anti-static brush for removing static electricity generated on the workpiece, and processing. Cutting guide to maintain the tension of the object and prevent the film from deforming When configured with a reed switch for sensing the passage of the laminate and the pre-cut individual workpieces, a counter for calculating the coating number is transmitted a signal of the reed switch, the.

Further, the paper feed tray is installed almost perpendicular to the main body, and a lower portion of a work placed there is brought into contact with a supply roll so that the paper can be continuously supplied.

Further, the standby roller stops the operation for a predetermined time if any one of the left and right end portions of the workpiece that has passed the supply roller is first contacted, and restarts the operation if the remaining portion is contacted. The tip of the object is rearranged.

Further, the supply clutch is fixedly connected to the supply roller through a fastening screw to which a loosening prevention liquid is added so as to prevent deformation and loosening.

Also, the rear lid and the main body are formed with protrusions and support grooves on both sides to prevent the roller arrangement from being displaced during coupling, and the protrusions are completely inserted and fixed in the support grooves. .

Second, a cover is installed on the main body so as to be openable and closable, and a heating roller and a pressure roller, which are installed in close contact with each other, are installed so that they can be separated from each other. Processing when a jam occurs can be simplified. Third, by installing an automatic cutting machine with a cutting guide plate, it is possible to prevent the deformation of the film and to cut the workpiece with desired dimensions accurately. Fourth, static electricity generated by the heat and pressure applied when forming the coating film on the workpiece is removed by the antistatic brush installed inside the main body, and the heating roller is made of aluminum to reduce the heat required for coating. The time for generation can be greatly reduced. Fifth, a counter can be installed to control the number of coatings and to know the endurance year and the number of times of use in advance, thereby maximizing production efficiency through replacement and repair of the corresponding parts.

A fixed cutter 19 and a rotary cutter 19 'are provided on one side of the pressure rollers 18, 18' so as to cut the coated workpiece.

At this time, the timing of the rotary cutter 19 'is adjusted according to the size of the workpiece so that the workpiece can be cut in response to a signal input in advance.

In addition, a cutting guide plate 70 is provided above the rotary cutter 19 'so that the tension of the workpiece immediately before cutting is kept sharp so as to prevent deformation of the film and the workpiece does not touch the rotary cutter 19'. Is done.

In addition, the heating rollers 13, 13 'and the discharge rollers 23, 23' are provided with an antistatic so as to remove static electricity generated by heat and pressure applied to coat a workpiece on a film. By installing the brush 24, it is possible to prevent the loading position from being uneven due to the electrostatic action between the workpieces when the coated workpiece is loaded on the discharge tray 6.

On the other hand, the film roller 11, the heating roller 13, the pressure roller 18, the fixed cutter 19, and the like are fixedly coupled to the upper support plate 21, and the upper support plate 21 is lifted upward by a predetermined angle. Hinged to the side. The film roller 11 ', the heating roller 13', the pressure roller 18 ', and the rotary cutter 19' are fixedly installed on the lower support plate 21 '.

Further, a “U” -shaped reinforcing base (not shown) is preferably installed at a predetermined portion (two places in the drawing) of the lower support plate 21 ′ to suppress distortion of the lower support plate 21 ′ due to product movement or the like. I do.

On the other hand, protrusions 80 are formed at predetermined portions on both sides of the rear cover 8, and support grooves 90 are formed at predetermined portions on both upper portions of the main body 1. The roller is inserted and fixed in the groove 90 so that various roller arrangements can be accurately performed to improve coating efficiency.

In addition, by measuring the number of times the workpiece is coated on the discharge port 5 of the main body 1 and grasping the life of various parts, the performance parts are periodically replaced after reaching the specified number of sheets or the end of the endurance year. The reed switch 26 and the counter 27 are linked and installed so as to be able to.

動作 An operation of coating a synthetic resin material on a workpiece such as paper using the laminator configured as described above will be described.

First, in order to mount the upper roll film F and the lower roll film F ', the upper roll film F opens the rear lid 8 to the left in FIG. 3, and the lower roll film F' opens the front lid 7 to the right. And can be easily attached to each of the film rollers 11, 11 '.

After the mounting of the roll films F and F 'is completed, the upper support plate 21 is lifted upward so that the upper roll film F covers the upper heating roller 13 and the lower roll film F' is placed on the lower heating roller 13 '. Each roll film F, F 'is stacked on the loaded state, passed over the guide plate 22, passed through the pressure rollers 18, 18' and the cutters 19, 19 ', passed through the discharge rollers 23, 23', and After the front ends of the roll films F and F 'are pulled out to the outside, the front lid 7 and the rear lid 8 are sequentially closed to complete the mounting of the roll films F and F'.

At this time, each film sensor 12, 12 'senses whether the roll film is mounted on each film roller 11, 11', and either one of each film roller 11, 11 'is not mounted or When the film is exhausted during operation, the sensing sensors 12, 12 'sense this and input it to the microcomputer 100, so that the lamp unit 91 for indicating the presence or absence of the roll film under the control of the microcomputer 100 is turned on. You.

Further, when the workpiece and the roll film are not transferred normally or the cutters 19 and 19 'are not normally operated and the automatic cutting is not performed, the lamp unit 91 is turned on to stop the operation of the entire laminator. Then, a message appears asking whether a roll film is to be attached or an error is to be checked.

Next, when the power of the power supply unit 40 is applied and the heaters 30, 30 'generate heat under the control of the microcomputer 100, the surface temperature of the heating rollers 13, 13' reaches a specified value (in the present invention, approximately 110 ° C.). , The signal of the lamp unit 91 changes from blinking to lighting. Accordingly, when the coating start button is pressed, the drive motor 20 is rotated, and the clutch controller 28 receiving the control signal from the microcomputer 100 operates the supply clutch 29 to control the transmission of the driving force to the supply roller 9 by operating. The workpiece is continuously moved one by one toward the standby rollers 10, 10 '.

The workpiece moved by the supply roller 9 is slightly stopped by the standby rollers 10 and 10 'so that the right and left end portions are accurately aligned without displacement, and then passes through the heating rollers 13 and 13'. At this time, the microcomputer 100 determines that the workpiece has passed the standby rollers 10, 10 'by processing the sensing signal of the sensing sensor 60, and the film is pulled out from the film rollers 11, 11' by the control of the microcomputer 100. It is located on the upper and lower surfaces and is bonded to the workpiece by heating the heating rollers 13, 13 '.

Next, the film is transferred to the cutters 19 and 19 'while the tension is supported by the cutting guide plate 70 while the film is firmly pressed on the upper and lower surfaces of the workpiece while passing through the pressure rollers 18 and 18'. The cutters 19 and 19 'cut only the film adhered to the upper and lower surfaces between the top and bottom surfaces of the workpiece by 5 to 15 mm (adjustable) due to the inflow of the front end of the workpiece. After being automatically cut at the end of 5 to 1 mm (adjustable), it passes the reed switch 26 past the discharge rollers 23 and 23 ', and the counter 27 calculates the signal sent from the reed switch 26 and sequentially adds the number of coating times. I do.

(5) By transferring the cut film and workpiece to the discharge tray 6, the process is completed. At this time, while the workpiece passes through the antistatic brush 24 installed near one side of the heating rollers 13, 13 'and one side of the discharge rollers 23, 23', static electricity generated by heating and pressing is removed. By being discharged to the discharge port 5 in a state in which the sheets are placed, the sheets are sequentially stacked on the discharge tray 6 without any separate manual rearrangement.

On the other hand, when the roll film is not mounted or when the roll film is completely exhausted, the roll film lamp is turned on to stop the operation of the roll laminator, and the workpiece and the roll film are not transferred normally or the cutter operates normally. If not, the paper jam lamp is turned on to stop the operation of the automatic roll laminator, thereby preventing a process error during the coating operation.
