Description

  In the present invention, a transparent or translucent laminate film coated with an adhesive on one side is pasted on the surface of a printed matter such as a poster or an advertisement, or an output medium of a computer (hereinafter referred to as a medium). It relates to a laminating apparatus used to form a laminate that improves the water resistance and weather resistance of media by protecting it. More specifically, a release paper attached to the adhesive-coated surface of a laminate film is laminated and laminated. The present invention relates to a laminating apparatus capable of accurately and easily performing an operation of peeling from a film and winding it around a release paper winding paper tube.

  Hereinafter, a conventional laminating apparatus described in Patent Document 1 will be described with reference to FIG. As shown in the partially enlarged view of FIG. 8 (b), the laminate film original fabric 4 is obtained by applying an adhesive to one surface of a transparent or translucent film A such as polyester or vinyl chloride, and applying the adhesive to the surface of the adhesive surface. A long laminated body to which the release paper B is bonded is wound around a core (paper tube).

  A conventional laminating apparatus for coating such a laminating film in close contact with the surface of the media includes a frame 1 fixed in parallel on both the left and right sides of the frame, and the frame 1 includes a shaft of a conveying roller 3. 31, a shaft 41 that supports the core of the laminate 4 of the original film 4, a shaft 51 that supports the core of the film 5 of the transport film C, and the release paper B peeled off from the laminate film A A shaft 42 that supports the winding core to be wound and a shaft of the peeling guide roller 8 are mounted.

  Further, a table 11 for feeding the medium M is fixed between the frames 1.

  The conveying roller 3 pivotally supported between the left and right frames 1 is driven by a motor 30, and a pressure roller 6 is provided on the upper portion of the conveying roller 3 so as to form a pair vertically.

  The shaft of the pressure roller 6 is held by a bearing provided on the movable plate 61. One end of the movable plate 61 is supported by the frame 1 and the other end is a pressure roller up / down lever. The pressure roller 6 is separated from the conveying roller 3 by being moved up and down by a cam 64 and a rod 65 rotated by 63.

  As shown in the enlarged view of FIG. 8B, the laminate film has a double structure (generally called a cold laminate film), and the lower side of FIG. 8B is a transparent and translucent laminate film. Yes, the upper side of the figure (the side that becomes the back side when pasted) is coated with an adhesive. The release paper B and the laminate film A are bonded together by this adhesive, and when the release paper B is peeled off from the laminate film A, the adhesive remains on the laminate film side and adheres to the media surface.

  Next, a preparatory operation before starting the laminating process will be described with reference to FIG. First, the operator operates the pressure roller up / down lever 63 to move the pressure roller 6 away from the conveyance roller 3 and to remove the original film for conveyance for conveying a poster or the like to be laminated. It is set on the shaft 51 of the transport film, and the original film 4 of the laminate film is set through the shaft 41 of the laminate film.

  Next, the front end of the original film for conveyance 5 set on the axis 51 of the conveyance film is pulled out, guided onto the entrance table 11, and passed through the gap between the pressure roller 6 and the conveyance roller 3 to the rear ( Pull out to the discharge side.

  Subsequently, the front end of the laminate film raw material 4 set on the laminate film shaft 41 is pulled out, wound around the pressure roller 6, and pulled out to the rear (discharge side) of the laminating apparatus. At this time, the laminate film in which the laminate film A and the release paper B are integrated is overlaid on the transport film C.

  When the operator operates the pressure roller up / down lever 63 again to lower the pressure roller 6, the laminate film A and the transport film C with the laminate film A and the release paper B being integrated are both rollers. It is sandwiched in a state of being polymerized between.

  Next, the operator goes to the rear side (discharge side) of the laminating apparatus and cuts only the release paper B from the rear side of the peeling guide roller 8 over the entire width of the laminate film A using a dedicated cutter knife or the like. At this stage, the release paper B is separated forward and backward by the cut, but remains attached to the laminate film A, and the cut portion becomes the leading edge of the release paper.

  Thereafter, the operator presses the “operation switch” on the operation unit to rotate the conveying roller 3, and the cutting position of the release paper B passes below the peeling guide roller 8 and approaches the front surface of the pressure roller 6. Then, the “operation switch” is pressed again to stop the conveying roller 3.

  The operator turns to the front of the laminating apparatus (document insertion side), peels the tip of the release paper B attached to the laminating film A by hand, and presses the “operation switch” of the operation unit again to carry the conveying roller. 3 is rotated. When the transport roller 3 rotates, the laminate film A and the transport film C from which the release paper B has been peeled are inserted into the gap between the pressure roller 6 and the transport roller 3.

  Here, the operator pulls the leading edge of the release paper B forward, visually observes the length of the release paper B peeled off from the laminate film A, and when the length is just right, press the “operation switch” again to carry it. The roller 3 is stopped, and finally, the leading edge of the release paper B is lifted up to the release paper winding paper pipe and is attached to the paper pipe with tape or the like. This completes the preparation for lamination.

Japanese Patent No. 3901464

  In the conventional laminating apparatus described above, during the operation of attaching the tip of the release paper B to the release paper take-up paper tube, the operator determines that the length of the release paper B peeled off from the laminate film A is the release paper take-up length. The motor must be stopped and the pressure roller 6 must be stopped when it is just long enough to be attached to the paper tube. During this operation, the transport film C discharged backward from the pressure roller 6 If attention is paid to the state of both films on the rear side (discharge side) of the laminating apparatus so that wrinkles are not generated in the joining of the laminating film A, the pressure roller 6 stops earlier or is delayed. Even if the pressure roller 6 is stopped and the release paper B is cut, if the tip of the release paper B is peeled off from the laminate film A and attached to the release paper take-up paper tube, the release paper B is short and the release paper winding is performed. If may not reach the paper tube, also too long it occurs.

  If it takes a short time, the “running switch” is pressed again to rotate the pressure roller 6, and the release paper B is dragged into the gap between the pressure roller 6 and the conveying roller 3 while being stuck to the laminate film A. It is necessary to perform an operation of pulling the leading edge of the release paper B toward the front while keeping it away.

  If it is too long, the work need not be repeated, but the laminate film A is wasted.

  In the above operation, the release paper B attached to the laminate film A must be peeled off and held firmly with both hands. It is necessary to push the “operating switch” by hand and then quickly return it to hold the tip of the release paper B, but it may be lost if touched during this operation. The feet must be quickly attached to the floor to achieve a stable posture. However, the posture may fluctuate and the release paper B is stuck to the laminate film A and enters the gap between the pressure roller 6 and the conveying roller 3. There is a chance. In this case, it is necessary to start from the work of cutting the release paper B and making a cut.

  As described above, it is difficult, troublesome, and accurate to cut the release paper B to make a leading edge, peel off the release paper from the laminate film A by just the right length, and attach it to the release paper winding paper tube. This requires considerable skill.

  Further, in the work of making a cut at the tip of the release paper B, the operator uses a dedicated cutter knife or the like at any position on the laminate film path from the upper part of the pressure roller 6 to the laminate film original fabric 4. Since the release paper B is cut to make a cut, the conveyance length of the laminate film A is not constant and is not fixed until the “operation switch” is pressed and the conveyance roller 3 is rotated and then stopped. It is a difficult factor to stop.

  Also, the worker reaches out from the back of the laminator and moves the cutter knife etc., but at that time the cutter knife may be moved diagonally, or the hand may be released in the middle, The cut surface may be slanted or jagged, causing the laminate film A to be wasted.

SUMMARY OF THE INVENTION The present invention solves the above-described problems. A laminate film, which is fed from a laminate film raw material and separated from a release paper, is applied to a surface of a printed material with a conveying roller whose rotation is controlled by a control unit and a pressure. In laminating equipment that transports between rollers and attaches laminating films to printed materials,
The control unit is configured to detect a laminate film length drawn from the laminate film original fabric,
An operation switch for operating a post-cueing operation instruction means for instructing the cue length of the release paper, which is a feed length from the release paper cutting reference position provided between the laminate film raw material and the pressure roller, and the end of the release paper There contacts the releasing guide for separating the release paper from the release paper cutting reference position, cueing operation instruction means for instructing a laminate film feed length is the distance to reach the peeling guide preparative release cigarettes arranged above device And
When the cueing operation instruction means turns on the cueing operation switch, the conveying roller is rotated according to the instruction of the cueing operation instruction means, and the cutting position of the release paper cut at the cutting reference position passes through the peeling guide. And when it reaches the position where it comes into contact with the peripheral surface of the pressure roller and is transported for the cue length, the transport roller is temporarily stopped,
When the cueing operation switch is turned on again after stopping for a certain period of time, the conveyance roller is rotated again, and the actual conveyance length of the laminate film reaches the release paper winding paper tube from the release paper cutting reference position via the release guide. The conveyance roller is stopped when the feed length is reached.

  Further, when the cueing operation switch is turned on, the conveying roller is rotated again after a certain delay time has elapsed.

Furthermore, guide rails for defining the release paper cutting reference position between the left and right frames for supporting the conveyance roller is laterally disposed, release paper cutting device having a disconnect blade along the guide rail slidably provided It is characterized by being.

  In the laminating apparatus of the present invention, the control unit determines the length of the release paper required to attach the leading edge of the release paper to the release paper winding paper tube, and peels it off the laminate film while rotating the conveying roller. When the release paper having a predetermined length is peeled off, the conveying roller is stopped so that no waste occurs in the laminate film.

  In addition, since the control unit rotates the conveyance roller after a delay time has elapsed since the signal generation of the “cue operation instruction unit”, the “cue operation instruction unit” is used as a “cue operation” switch of the operation unit. In this case, the operator must return the hand that pressed the “Cueing operation” switch, hold the tip of the release paper firmly with both hands, peel the release paper from the laminate film, and attach it to the release paper take-up paper tube. Can be done accurately.

  In addition, when the “cueing operation instruction means” is a foot switch, the operator can perform the pasting work in a state where one foot stepping on the “foot switch” is attached to the floor and the posture is adjusted.

  In addition, when the cutter knife slides around the laminating device by the auxiliary cutting means and slides the cutter knife, the lower projection of the cutter knife is held between the release paper and the laminate film even when the hand is released from the cutter knife. In addition, since the cutting assisting means can be slid along the guide rail, the cut surface does not become slanted or jagged, and the laminated film is not wasted.

The side view of the conventional laminating apparatus.

  FIG. 1 shows a state in which a preparatory step in the case of laminating using the laminating apparatus of the present invention is completed. The laminating apparatus of the present invention is used when laminating film A on an A1 or A0 size poster or a banner of a building. The width of the pressure roller 6 and the conveying roller 3 is about 1500 mm. The original laminated film 4 having a diameter of about 100 mm has a width of about 600 mm to about 1400 mm and a length of about 50 m.

  The laminating apparatus of the present invention will be described below. The frame 1 of the laminating apparatus includes a shaft 31 of the transport roller 3, a shaft 41 that supports the core of the original film 4 of the laminate film A, and a shaft that supports the core of the original film 5 of the transport film C. 51, a shaft 42 that supports a winding core for winding the release paper B peeled off from the laminate film A, and a shaft of a peeling guide roller 8 that separates the release paper B are mounted.

  Further, a table 11 for feeding the medium M is fixed between the frames 1.

  The conveyance roller 3 supported between the left and right frames 1 is driven by a motor 30, and a pressure roller 6 is provided so as to make a pair with the conveyance roller 3 in the vertical direction. Reference numeral 2 denotes a cutting reference position for cutting the release paper B, and the cutting device described in FIGS. 6 and 7 is provided at the cutting reference position.

  The shaft of the pressure roller 6 is mounted on a bearing provided on the movable plate 61. One end of the movable plate 61 is pivotally supported 62 on the frame 1, and the other end is rotated by a lever 63. The pressure roller 6 is separated from the conveying roller 3 by being moved up and down by a cam 64 and a rod 65 that are moved.

  After the operator operates the lever 63 to separate the pressure roller 6 from the conveying roller 3, the operator sets the original film 5 of the conveying film C on the shaft 51, passes through the idle roller 21 and the table 11. The roller 3 is inserted between the conveying roller 3 and the pressure roller 6. Next, the original film 4 of the laminate film A is set on the shaft 41, the leading end of the laminate film A is pulled out from the original film 4, the release paper B is peeled from the laminate film A, and the release guide roller 8 is passed through. The laminate film A, which is wound around the core supported by the shaft 42 that supports the core for winding the release paper B, is exposed between the transport roller 3 and the pressure roller 6 together with the transport film C. After insertion, the lever 63 is operated to lower the pressure roller 6. The above configuration and operation are the same as those of the prior art shown in FIG.

  FIG. 2 is a block diagram for controlling the laminating apparatus of the present invention, and is provided with a control device for CPU control. The control device of the present invention includes a measuring unit 14 composed of an encoder 13 coupled to the shaft of the pressure roller 6, a main arithmetic unit 15 including a CPU to which a pulse signal output from the encoder 13 is applied, The operation unit 16 for instructing the rotation speed and rotation direction of the motor to the main calculation unit 15 and inputting the length of the original film 4 of the laminate film A, the remaining amount of the original film 4 of the laminate film A, the motor 30 The display unit 17 displays a rotation speed, a rotation direction, and an alarm, a motor control unit 19 that controls the motor 30, and a storage unit 20.

  As switch means for controlling the motor, in the present invention, a cueing operation switch is provided in the operation unit 16, and a foot switch 18 may be provided as in the conventional apparatus.

  6 and 7 show the release paper cutting means of the present invention. A guide rail 32 is provided between the left and right frames 1 of the laminating apparatus, and a cutter knife mounting block 33 is slidably held by a groove provided in the guide rail 32.

  FIG. 7 shows the state of the cutter knife 34 and the laminate film A when the release paper B of the laminate film A with the release paper B attached to the laminate film A is cut over the entire width.

  As shown in FIG. 7A, the cutter knife 34 rotates left and right like a pendulum about the cutter knife attachment fulcrum 35. The blade 36 of the cutter knife 34 has an upper projection 36a and a lower projection 36b on the left and right side surfaces in the traveling direction, and the blade 36 is provided between the valleys of both projections.

  FIG. 7B shows a state when the cutter knife 34 is moved from the right side to the left side. When the operator moves the cutter knife 34 by hand, the lower projection 36b separates the release paper B from the laminate film A and enters the gap, and the release paper B is cut by the blade 36. Since the cutter knife 34 is held on the guide rail 32 by the cutter knife mounting block 33, the cutter knife 34 does not run diagonally. Even if the operator releases his hand during cutting, the lower projection 36b of the cutter knife 34 is held in a state where it enters the gap between the release paper B and the laminate film A.

  Next, with reference to FIG. 3, the process of cutting the release paper B of the laminate film A of the present invention and winding the release paper B around a winding core will be described. First, the operator cuts the release paper B over the entire width by using the cutter knife 34 installed at the cutting reference position 2 around the laminating apparatus. At this time, as shown in FIG. 3A, the leading edge of the release paper B is at the point B1 while being stuck to the laminate film A. Point A1 represents the position of the laminate film that is located immediately below when the release paper is cut across its entire width.

  For the cutting reference position 2, a mark 目 安 may be attached to the inside of the left and right frames of the laminating apparatus, and this may be used as a guide.

  Next, the operator presses a “cueing operation switch” provided in the operation unit 16 in order to move the front end of the release paper B at the point B1 to the front of the peeling guide roller 8. When the “Cueing operation switch” is pressed, the main calculation unit 15 constituting the control unit resets the counter to 0 in order to calculate the “laminate / film actual conveyance length” and then starts to rotate the conveyance roller 3. Then, the pulse signal from the measuring section 14 provided on the pressure roller 6 is counted to calculate the “laminate / film actual conveyance length”.

  When the “laminate / film actual transport length” reaches the “first feed length” stored in the predetermined storage unit, the transport roller 3 is stopped. The “first feed length” is the cue length of the release paper B by the distance from the leading end of the laminate film A to the peripheral surface of the pressure roller 6 from the peeling guide roller 8. At this time, the leading edge of the release paper B has reached point B2 in FIG. 3B, and the position of the laminate film A that has been located immediately below when the release paper B is cut has reached point A2.

  Next, the operator goes to the front of the laminating apparatus and peels off the release paper B from the laminating film A by hitting the front end of the release paper B at the point B2 as shown in FIG. The laminate film A is wound around the pressure roller 6 and is at point A2. Subsequently, when the operator presses the “cue operation switch”, the main calculation unit 15 of the laminating apparatus waits for “operation delay time”. During this time, the operator firmly holds the tip of the release paper B with both hands and prepares his posture. When the “operation delay time” has elapsed, the main calculation unit 15 instructs the motor control unit 19 to rotate and start the conveying roller 3. In the laminating apparatus of this embodiment, “operation delay time” = 0.3 seconds.

  The main calculation unit 15 continues the rotation of the transport roller 3 while calculating the “laminate / film actual transport length”. During this time, as shown in FIG. 3D, the operator can release the release paper B so that the release paper B is not dragged into the gap between the pressure roller 6 and the conveying roller 3 while being adhered to the laminate film A. Pull the tip of to the front. When the “laminate film actual transport length” reaches the laminate film “feed length”, the main calculation unit 15 stops the transport roller 3. At this time, the leading edge of the release paper B has reached point B3, and the position of the laminate film A that has been located immediately below when the release paper B has been cut across its entire width has reached point A3.

  The laminate film “feed length” is determined by the positional relationship among the laminate film original 4, the peeling guide roller 8, the pressure roller 6, and the release paper winding paper tube shaft 42, and is stored in the storage unit 20. In the laminating apparatus of the present embodiment, the leading edge of the release paper B is in contact with the peeling guide roller 8 from the point B1 (that is, the position of the “release paper cutting reference position”) and is disposed above the peeling guide roller 8. As the length of the laminate film (the length of the laminate film A from the points A1 to A3) equal to the distance (the length of the release paper from the point B1 to the point B3) reaching the pattern paper winding paper tube Laminate film “feed length” = 29 cm is stored in the storage unit in advance. The “first feed length” is the length of the laminate film equal to the length (the B1 point to the B2 point) that is equal to or longer than the length at which the leading edge of the release paper B passes below the peeling guide roller from the A1 point. , “First feed length” = 15 cm, stored in advance in the storage unit.

  The operator holds the tip of the release paper B in the state of FIG. 3 (d) up to the release paper take-up paper tube, and puts it on the release paper take-up paper tube with cello tape (registered trademark) or the like as shown in FIG. 3 (e). By pasting, the preparatory work for performing the lamination process is completed.

  Next, the operator places an original such as a poster on the transport film C on the entrance table 11 and presses the “laminate operation switch” of the operation unit 16. The main calculation unit 15 rotates the conveying roller 3, and the original document that has been laminated is discharged to the rear of the apparatus (right side in FIG. 1).

  FIG. 4 is a process for determining whether the main processing unit 15 of the laminating apparatus of the present invention executes a cueing operation or a laminating operation. In FIG. 4, it is discriminated whether the instruction of “Cueing operation” or “Lamination operation” is instructed in STP 1 and STP 2, and if it is an instruction of “laminating operation”, it is the same as the laminating apparatus of the prior art. The conveying roller 3 is rotated for laminating. If it is an instruction of “cue operation”, the process proceeds to STP4.

  FIG. 5 shows a process in which the main calculation unit 15 of the laminating apparatus of the present invention executes a cueing operation (peeling operation). At STP4, the conveyance roller 3 starts to rotate. In STP5, the pulse signals from the measuring section 14 are counted to calculate the “laminate / film actual conveyance length”. In STP6, it is determined whether or not the “laminate / film actual transport length” has reached the “first feed length”. If not, the process returns to STP4, and if it has reached, the process proceeds to STP7. The main calculation unit 15 stops the conveying roller 3 at STP7.

  In STP8, an instruction signal is generated from the “indexing operation instruction means”, and in STP9, after waiting for an operation delay time, the transport roller 3 is rotated and started in STP10. The operation delay time of the STP 9 is an additional time required for the operation of peeling the release paper B from the laminate film A over the entire width, and can be omitted. In STP11, the pulse signals from the measuring section 14 are counted to calculate the “laminate / film actual conveyance length”. In STP12, it is determined whether the “laminate / film actual transport length” has reached the “feed length”. If not, the process returns to STP8, and if it has reached, the process proceeds to STP11. In step STP13, the conveying roller 3 is stopped.

  As described above, the present invention improves the efficiency of the preparatory work by determining the peel length that the operator has visually determined at the stage of the preparatory work of the laminating process by the main arithmetic unit 15 by calculation. It is possible to prevent the waste of the film.

  In the embodiment of the present invention, the “cue operation instruction means” is a key switch dedicated to the cue operation instruction provided in the operation unit 16, but the foot switch 18 may be “cue operation instruction means”. Further, an operation unit 16 is provided with an “operation mode selection switch” for selecting whether the purpose of rotating the conveying roller 3 is to perform a cueing operation or to perform a normal laminating process. When the “Cueing operation mode” is selected by the “Operation mode selection switch”, if the “Operation” switch used in normal laminating is pressed, the cueing operation instruction is recognized. It is also possible to adopt a form. In the embodiment of the present invention, the first feed length and the feed length are measured by the encoder. However, the first feed length and the feed length may be controlled by commands of the rotation speed and the rotation time of the conveying roller.
