Abstract

PURPOSE:To enable to obtain unified high quality at an individual panel without making waste of labor for finishing work and a film generated, by carrying out cutting off of a continuous film without interrupting adhesion during a stage wherein the film is being made to adhere to the panel continuously. CONSTITUTION:When a panel 2 is suspended by positioning a front end part of the panel 2 at a continuous film tacking station 15, a tacking component 17 is moved through action of a piston cylinder device 18 while a film 6 is kept sucked, and the panel 2 is returned to an original receding position after tacking has been made by pressing the tip of the film 6 against a front end part of the panel 2. At the same time, a chain 13 is driven and the whole of a block component 11 is kept away from a position separated from the tacking station 15. Then when thermal pressure bonding of the film 6 is made on the panel 2 through a pressure roll 20 and a rear end of the panel 2 is detected by a sensor 40a, the whole of the block component 11 is made to approach to the tacking station 15 and the film 6 is cut off at the same time by rotating a cutter 27 and moving the same in the direction of a width of the film 6.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for attaching film sheets cut from a continuous film to panels, and a laminator for use therein.

For example, laminators for press-bonding a continuous photosensitive dry film cut into sheets onto a panel such as a glass epoxy copper clad laminate are conventionally known. The conventional method involves sequentially pressing a continuous film onto multiple panels conveyed by a conveyor such as a roller conveyor to form panels that are connected to each other, and then cutting the film to separate the panels. The process not only requires time and effort such as finishing work, but also
This resulted in wasted film. In order to solve this problem, an improved laminator has been proposed in Japanese Patent Laid-Open No. 52-14876.・In this laminator, the tacking member operates to tack the leading edge of the continuous film to the front edge of the panel being conveyed by the belt conveyor, and then the film is attached to the nookunnel. When a flannel is temporarily attached between a pair of crimping rolls and passes a predetermined length along with the film, the operation of the crimping belt conveyor starts (
・It will be stopped suddenly. After stopping, the continuous film is cut with a cutter to a predetermined length (1/C), and the pressure roll is operated again to deposit the remaining portion of the film on the groove. Therefore, the film is cut into sheets of a size corresponding to each groove and attached in a t-shaped state, so there is no need to cut the film during finishing work.
Also, the amount of film wasted is 93 times (1 degree).However, in this improved laminator,
During the film crimping process, the crimping roll is temporarily stopped on the channel and restarted after the film is cut to complete the crimping process. This results in a foreign part being formed.

Therefore, uniform high quality cannot be obtained in each individual panel.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a film adhesion method and a laminator for use in the method, which can achieve uniform high quality in each film without requiring finishing work or wasting film.

In the laminator described in the above-mentioned Japanese Patent Application Laid-open No. 52-14876, the pressure roll is forced to stop once on the panel in order to cut the continuous film attached halfway to the panel into sheets. However, according to the present invention, it is possible to cut the running film to the correct size in the horizontal direction without interrupting the film adhesion work by the pressure roll. Surface inhomogeneities are eliminated.

In the present invention, "one-time bonding" includes various types of bonding such as thermocompression bonding, pressure bonding without using heat, and bonding using an adhesive. In addition, "panels" can be made of glass epoxy copper-clad laminates and iron plates, as well as plastic, paper, and other materials depending on the purpose, and "films" can be made of photosensitive films, masking films, and other covering films. Hereinafter, the present invention will be described in detail with reference to accompanying drawings showing a preferred embodiment of the present invention.

As shown in FIG. 1, the laminator according to the present invention includes a laminator main body 1, an entrance roller conveyor 6 and an exit roller conveyor 4, which serve as conveyance devices for conveying panels 2 before and after the main body 1. Contains. Since the film is normally required to be placed on both the upper and lower surfaces of the panel 2, the laminator main body 1 has a structure that is vertically symmetrical with respect to the conveyance path of the panel 2. Therefore, in the following description, only one (upper) structure will be described in detail.

The detailed structure of the laminator main body 1 is shown in FIGS. 2 to 5. The laminator main body 1 has side plate-like support members 5 (only one is shown) on both sides. A film supply roll 7 on which a continuous film 6 is wound, and a take-up roll 9 for winding up a protective film 8 covering the film 6 during film supply are mounted between the supporting members 5 on both sides. ing. Guide rail 1 fixed to each support member 5
Each block member 11 is connected to a chain 13 stretched around a chain wheel 12 provided on each support member 5. They are connected via a member 14. Therefore, by driving the chain 13, each block member 11 can be moved toward and away from the continuous film tacking station 15 of the laminator.
A temporary attachment member 17 is laterally attached so as to be movable along the cam groove 16. The temporary attachment member 17 is connected at both ends to a piston cylinder mechanism 18 attached to each block member 11, and is driven by the piston cylinder mechanism 18. In addition, the tentative publication is part 17
At both ends, racks 19 are formed to extend upward, and the racks 19 are connected to the block members 11 on both sides.
They are respectively engaged with pinions 21 at both ends which are connected to each other by a pinion shaft 20 supported therebetween. Therefore, by simultaneously operating the piston cylinder mechanisms 18 on both sides, the tacking member 17 can be moved up and down evenly left and right by the synchronized action of the pair of pinion rack mechanisms on both sides of the pinion shaft 200. Further, the pinion shaft 20 serves as a pivot when the member 17 moves along the cam grooves 16 on both sides during temporary attachment. In this way, VC
7, by the operation of the piston cylinder mechanism 18, the web tacking can be moved toward and away from the panel 2 transported to the station 15 ``1''.

For tacking, the member 1711 has the role of guiding the continuous film, and also performs tacking work while adsorbing the film, as will be described later. Therefore, a plurality of rows of vacuum suction holes 22 are provided in the suction guide surface of the tacking member 17 in the width direction of the film. Each hole 22 communicates with a vacuum generator (not shown). Each hole 22 is controlled by a valve so that it can be operated selectively for each row, and the valve is opened or closed depending on the width of the film to be applied.

A bracket 26 is attached to the lower part of each block member 11, and a guide bar 24 extends between the brackets 23 on both sides.
A cutter 27 held by a cutter holder 26 is mounted on the rack 25. The cutter 27 has the shape of a rotating round blade, and is rotated by a single motor attached to the cutter holder 26. At the same time, the pinion attached to the motor rotates and engages with the rack 25, so that the cutter 27 moves along the cutter holder 26 on the guide bar 24 in the lateral direction with respect to the block member 11, and cuts a continuous film. can be cut. Note that a separate motor may be used to move the cutter 27 laterally. When cutting the film, the cutter 27 moves along a horizontal groove 29 provided in a cutter guide 28 whose both ends are fixedly supported by the lower ends of each block member 11.

Temporarily attach the member 1 to the film guide surface of the cutter guide 28.
Similar to 7, holes 28' for vacuum suction are provided along the width direction of the film, and each hole is controlled by a valve so that it can be selectively operated according to the width of the film. It is also possible to use a piston-cylinder mechanism instead of a motor as the driving means and to rotate the cutter 27 and move it laterally using a pinion rack mechanism.

A pressure roll 60 for pressure-bonding the film to the panel 2
At least one of the other pair of pressure rolls 60 provided above and below with respect to the conveyance path of the panel 2, for example, the upper pressure roll 60, is attached to the left and right support members 5 as shown in FIGS. 6 and 7. The slide bases 32 are rotatably supported at the lower ends of slide bases 32 connected to respective piston cylinder mechanisms 31. By the operation of the piston cylinder mechanism 31, the system slide base 32 slides up and down along guide rollers attached to the support member 5, and the upper crimping roll 60 moves up and down according to the thickness of the wall 2. . Each slide base 32 is provided with an opening 64, and a rack 65 is formed on the side edge of the opening 64. rack 3
5 is engaged with a pinion 66, and the pinions 66 on both the left and right sides are connected to each other by a pinion shaft 37 that extends laterally through the support member 5. therefore,
Since the upper crimping roll 60 is moved up and down equally on the left and right,
A uniform pressure is always applied to the panel 2.

1. As shown in FIG. 7, the engagement point between the rack 65 and the pinion 36 is positioned within the plane defined by the central axis of each pressure roll 60, so that the slide base 62 is not tilted. ing.

As shown in FIGS. 2 to 5, a film guide 38 for guiding the film extends in the lateral direction at a position adjacent to the front of the pressure roll 30. As shown in FIGS.

Similar to the member 17 and the cutter guide 28, the guide surface of the film guide 68 is also provided with multiple rows of vacuum suction holes 69 along the width direction of the film, and valves are provided to selectively operate each row. controlled.

The laminator according to the invention operates as follows.

Panel 2 preheated with a heater to improve thermocompression bondability
However, the laminator main body 1 is
When the sensor 40a detects the tip of the panel 2, the signal causes the drive rollers 41a to 41g to move.
transports the Nominel 2 until its front end is at the continuous film tacking station 15, where the operation is stopped.

However, among the sensors 40b to 40f, if there is a sensor 40C that does not detect the panel in the middle, as shown in FIG. 1, only the drive rollers 41a and 411) on the downstream side of the sensor 40C stop, and 41c to 41g remain driven. Therefore, the succeeding panel 2' is transported even while the preceding panel 2 is at rest. When sensor 40C senses the leading edge of panel 2', drive rollers 41C to 41.9 are also stopped to avoid collision between the panels. By operating the drive rollers individually in this way and shortening the distance between the stopped preceding panel and the following panel, waiting time can be greatly reduced. Therefore, it is particularly effective in improving productivity when the length of the tunnel to be processed is not constant.

When the panel 2 positions its front end at the continuous film tacking station 15 and stops, the tacking member 17 at the position shown in FIG. Panel 2 due to operation
The front end of the film A is pressed against the front end of the panel 2 and temporarily attached (see FIG. 6). During this temporary attachment, the holes 28' of the cutter guide ``28'' and the holes 69 of the film guide ``38'' are all kept inactive.

After the temporary attachment is completed, the temporary attachment member 17 is returned to the original retracted position. At the same time, the chain 16 is driven, and the block member 1
The entire continuous film tacking is moved away from station 15 (see FIG. 4). The drive rollers 41a to 41g are then actuated and the continuous film 6 begins to be thermocompressed onto the panel 2 by the pressure roll 60.

The film crimping work progresses as the panel 2 is transported, and when the sensor 40a detects the rear end of the panel 2, the chain 16 is driven by the signal, and the entire block member 11 is brought close to the continuous film tacking station 15. At the same time, the cutter 27 rotates and moves laterally relative to the block member 11 to cut the film. At this time, the moving speed of the block member 11 is made equal to the conveying speed of the input roller conveyor B, that is, the traveling speed of the film B. Since the cutter 27 is attached to the block member 11, the continuous film tacking moves toward the station 15 together with the block member. Therefore, during this close movement, the film 6 and cutter 2
7, there is no relative speed in the film running direction,
By moving the cutter 27 in the transverse direction, that is, in the width direction of the film, the continuous film 6 is cut horizontally into a rectangular film sheet. The cutting position of the film 6 and thus the length of the film sheet corresponds to the point in time when the blocking member 11 starts its approaching movement. By controlling and processing the signal of the sensor 40H so that the block member 11 starts moving closer a certain period of time after the sensor 40a senses the rear end of the panel 2 and issues a signal, the length of the film sheet can be adjusted to the length of the panel 2. By adjusting the length of the film, you can use the film without wasting it. The cutter 27 only needs to complete the cutting operation while the block member 11 is moving toward the block member 11, and the cutting speed can be set arbitrarily.

° Even during the film cutting operation, the film crimping operation by the crimping roll 60 continues without interruption, and after the film is cut, the film sheet is completely crimped onto the nominal panel 2, and the tacking member 17 is attached to the subsequent panel 2'. For continuous film tacking, the leading edge of the continuous film is held by suction in preparation for work (see Figure 5). The same operation is then repeated for subsequent panels.

The position of tacking the film and the cutting position must be strictly controlled in relation to the conveyance of the panel by the input roller conveyor. Therefore, a rotary encoder 42 that receives signals from sensors attached to each drive roller may be used.

As described above, according to the present invention, since the film sheet is attached while being cut according to the length of each panel, there is no need for finishing work or waste of film, and Since the pressure roll is not stopped on the panel during film pressure bonding, uniform high quality can be obtained for each panel.

In the present invention, the cutter may be any known cutting tool other than a rotary round blade. Also, other known drive means may be used instead of the piston cylinder mechanism or chain mechanism.

When attaching a film to both sides of a panel, each member of the laminator body is installed in pairs vertically symmetrically with respect to the panel conveyance path, but when attaching a film to only one side of the panel, it is sufficient to install it on either one. .

Further, the laminator main body may be configured so that the entire laminator body can be pulled out laterally by a slide 9 rail, which is convenient for maintenance.

Vacuum suction holes provided in the tacking member, cutter guide'' and film guide may be operated by separate vacuum generators, but preferably all holes are operated by a single vacuum generator. It is assumed that the vacuum suction holes are connected to a generator (e.g., a vacuum pump) in each of the temporary attachment member, the cutter guide, and the film guide, in one or more rows along the film width direction. Each branch pipe is connected to a branch pipe, and each branch pipe is provided with an on-off valve.In addition, each branch pipe has one main pipe for each member, cutter guide, and film guide. Each of the main pipelines is also provided with an on-off valve.When temporarily attaching the film, the on-off valves of the main pipelines that communicate with the cutter guide 9 and the film guide are closed, and the temporary attachment is performed only on the members. Vacuum suction is effected.The respective main lines are connected directly or combined into one main line to a single vacuum generator.
