BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a laminator 1 according to the embodiment.
FIG. 2 is a side view of the laminator 1, in which a laminator 1 is provided with a machine frame 2 and a work loading conveyor 4 (loading mechanism) provided therein.
The upper and lower feeding shafts 6, the original reversing direction shafts 7, the take-up shafts 8, the two release paper turning shafts 9, the cutter 10 and the plate 11, the upper and lower rollers 12 and the chuck 13 and the servo motor 14 in the substantially center, and the upper and lower parts It is provided with two welding machines 15, a finished product delivery conveyor 16 and an operation panel 18.

The work feeding conveyor 4 can convey a work (here, the substrate W) substantially horizontally to the left side in FIG. 1, that is, the downstream side by a servo motor (not shown). The feeding shaft 6 can be set with a roll R as an original fabric. The original reversal axis 7 is provided with a film F having a release paper S inside, which is pulled out from the roll R, and a roller 12
Turn to a distance. The take-up shaft 8 and the release paper turning shaft 9 wind up the release paper S peeled from the film F by a servo motor (not shown).

The cutter 10 approaches the film F from the outside in the width direction by an actuator (not shown) and moves the rotary blade 20 protruding in the thickness of the film F as it is in the width direction while rolling on the film F. Cut in the width direction.

The plate 11 is arranged so as to match the supply angle of the film F and reach the vicinity of the upstream side between the rollers 12, and supports the film F while the cutter 10 is running, or at the side of the roller 12 side. The release paper S is folded back and peeled off from the film F. The side of the chuck 13 has a knife edge 11a whose outer corner has a sharp angle.
It is said that. The roller 12 contacts the film F supplied to the substrate W, and covers (laminates) the film F on the substrate W when the substrate W moves downstream by the chuck 13.

In this embodiment, the knife edge 11 is used.
a plate 11 provided with a, a feeding shaft 6, a winding shaft 8,
Since the cutter 10 and the like are provided above and below, the film F
Can be introduced on the front and back of the substrate W.

The chuck 13 is a pulling mechanism that holds and pulls the substrate W and the film F. That is, the upper and lower claws 22 can be driven by an air cylinder (not shown) to grip the edges of the substrate W and the film F, and the pinion 24 at the tip of the rotary shaft of the servo motor 14 provided integrally on the rack 26. By traveling along, it is possible to move substantially parallel to the top of the substantially horizontal finish product delivery conveyor 16.

The welding machine 15 is a fastening mechanism for partially stopping the coated film F on the substrate W, and is provided with a head 28 having a heating portion at its tip and vertically moved by an air cylinder (not shown), Two heads 28 are provided on each side of the film F so that the heads 28 can advance to both sides. The head 28 can stop the film F on the substrate W at a dot-like portion by bringing the heated tip into contact with the film F.

The finished product delivery conveyor 16 is driven by a servo motor (not shown) and conveys the substrate W with the film F received from the chuck 13, that is, the finished product downstream. The operation panel 18 synchronously controls the servo motors, the air cylinders, the take-up shaft 8, the release paper turning shaft 9, the welding machine 15 and the like in accordance with the state of its own switch (not shown), so that the entire operation of the laminator 1 is performed. Control

In laminating on the upper surface of the substrate W by the laminator 1, the film F is initially positioned in front of the chuck 13 after passing from the roll R of the payout shaft 6 over the plate 11 and between the rollers 12. Pull it out to do so. In addition, the knife edge 11a near the roller 12
The release paper S is folded back in and set so as to be wound around the winding shaft 8. Further, the tip of the head 28 of the welding machine 15 is warmed.

Then, as shown in FIG. 2A, first, the operation panel 18 drives the work feeding conveyor 4, and the substrate W is contacted with the front end (downstream side end) of the film F with a predetermined margin M secured. Transport it to the desired position. At this time, the area slightly upstream of the margin M of the substrate W passes between the upper and lower rollers 12 together with the front edge (downstream edge) of the film F and is covered. At the time of this coating, the release paper S is peeled off at the knife edge 11a arranged near the upstream side of the roller 12, and thus the film F immediately after peeling is coated on the substrate W. Further, the front end edges of the substrate W and the film F are
Since the chuck 13 is located inside the claw 22 of the chuck 13, the chuck 13 holds the front edge of the substrate W and the film F by the claw 22.

Next, as shown in FIG. 2 (b), the chuck 13 is moved downstream by driving the servo motor 14 while holding the front edge of the substrate W and the film F. This movement causes the roller 12 to rotate, and the film F to move to the substrate W.
It is laid flat on. In this case as well, the knife edge 11a near the roller 12 supplies the film F just peeled to the roller 12.

Further, at a predetermined timing during this movement, the head 28 of the welding machine 15 is moved up and down to bring the tip of the head into contact with the film F and attach a predetermined portion of the film F to the substrate W.
Examples of the predetermined portion include the vicinity of the diagonal or four corners of the film F, and the vicinity of a portion where the sides are equally divided into two or ten.

Subsequently, as shown in FIG. 3C, the substrate W
The blade 2 of the cutter 10 from the front end of the film F not riding on the blade
When the length L1 in the longitudinal direction of the film F up to 0 becomes substantially equal to the length L2 from the front end to a portion that is moved back by the margin M from the rear end (upstream end) of the substrate W, the winding is performed. Stop the take-off shaft 8, the release paper turning shaft 9 and the chuck 13 once,
The cutter 10 is moved in the width direction of the film F to cut only the film F on the release paper S (half cut).

Then, as shown in FIG. 3D, after the cutting of the film F is completed, the cutter 10 is returned and the chuck 1
The movement of the substrate W and the film F due to 3 or the like is restarted. In this way, the film F rides flat on the substrate W up to the rear end formed by cutting. At this time, due to the cutting by the cutter 10, the margin M also remains on the rear side. The margin on the side can be adjusted by the width and position of the roll R. After that, the chuck 13 is moved slightly downstream while opening the claw 22, and the substrate W coated (internally adhered) with the film F in a state where there is a margin is placed on the finished product delivery conveyor 16 to be downstream as a finished product. send. Then, the substrate W is put into the state of FIG. 2A, and the above operation is repeated as appropriate.

In the laminator 1 as described above, by disposing the knife edge 11a of the plate 11 on which the release paper S of the film F is folded back, in the vicinity of the upstream side of the roller 12, the release paper S is transferred to the film F. Since it is peeled off immediately before being covered by the roller 12, the possibility that dust will adhere to the film F itself attached to the substrate W is extremely low. Also, the plate 11 or knife edge 11
Since only the release paper S comes into contact with a, the film F itself is not scratched. Therefore, the laminator 1 can provide an extremely high quality finished product.

Further, since the film F is introduced into the front and back of the substrate W and the plate 11 is provided for each film F, the front and back of the substrate W can be simultaneously laminated without dust or scratches.

Further, since the side of the plate 11 on the roller 12 side is the knife edge 11a, the release paper S can be folded back at an acute angle to improve the peeling and sharpen as the roller 12 is approached. The folded-back portion of the release paper S can be arranged very close without interfering with the roller 12, and the finish can be further improved.

Further, since the cutter 10 for performing the half cut for cutting only the film F without cutting the release paper S is provided, the film F for each substrate W is formed from the roll R as the raw material, and each substrate is formed. The films F can be successively supplied to W, and a large number of substrates W can be continuously laminated with high quality.

In addition, since the plate 11 is placed along the film F or the release paper S, and the cutter 10 is opposed to the plate 11, the pressing of the cutter 10 on the plate 11 for separating the release paper S immediately before lamination is performed. It can also play a role, and can have a simple structure while ensuring the stability of half cut.

In the laminate 1, the film F and the substrate W are supplied while the film F is being supplied to the substrate W.
And the chuck 13 whose front end edges are held by the claw 22.
The film F rides flat on the substrate W because it is pulled by. Therefore, it is possible to apply a laminate in which the film F is laid flat and lightly on the substrate W. In addition, such a soft and flat laminate is suitable for temporary lamination (temporary attachment) in the previous stage for vacuum lamination or high pressure bonding lamination. Further, by setting the pulling speed at a substantially constant speed, the quality of the laminate such as placing the film F thereon becomes better, but the speed may be variable.

Further, a release paper S is provided on the film F, these are pulled out from the roll R set on the feeding shaft 6, and the release paper S is folded back at the edge of the plate 11 and taken up by the take-up shaft 8 while peeling off. F is supplied, and the cutter 10 cuts the film F without cutting the release paper S for each substrate W. Therefore, the supply of the film F is simple and rational, and Light and flat lamination can be carried out continuously on the substrate W.

Further, the front end of the film F is supplied to a position behind the front end of the substrate W by a margin M, and the rear end of the film F reaches a position before the rear end of the substrate W by a margin M. Since the film F before being supplied to the substrate is cut by the cutter 10, by appropriately adjusting the width of the film F, the inner sticking of the margin M can be easily realized even in a soft and flat laminate.

In addition, the plate 11 follows the film F before being supplied and supports it, so that the film F hangs down and wrinkles and adheres to the substrate W, or detaches from the substrate W and is supplied to the substrate W. It is possible to prevent the situation from disappearing. In the laminator 1, the plate 11 is used for supporting the film F before feeding, peeling the release paper S, and pressing (support at the time of cutting) on the side opposite to the cutter 10, which results in a very efficient structure. Have contributed.

Further, since the film F supply mechanism, the fastening mechanism, and the like are provided in the upper and lower sides, it is possible to perform a laminating process which is flatly placed on the upper and lower two surfaces of the substrate W, which is efficient. In addition, since a part of the film F is stopped on the substrate W by the welding machine 15, it is possible to prevent a situation in which wrinkles and deviations are generated after finishing or in the next step due to light weight of the laminate.

The present invention is not limited to the above embodiment, but can be variously modified without departing from the present invention, as will be partially shown below.

While the cutter is moving in the width direction, the cutter is also moved at substantially the same speed as the film F in the feeding direction of the film F, and the film F that is advancing is cut in the width direction. You can In this case, the finish is accelerated by the amount by which the progress of the film is not stopped, and it is possible to prevent wrinkles, lines, and deviations from occurring because the lamination does not have to be stopped, and a uniform finish can be obtained.

The pulling mechanism may be a moving plate on which the work can be placed, and the work may be placed on the moving plate after the front edge of the film is fixed. Chuck is
It is also possible to grasp the side edges of the film and the work.
The margin M may be different before and after, or may not be provided.

Further, a laser cutter can be used as the cutter, a head or a roller that rolls on the side edge can be adopted as the fastening mechanism, and the heating section can be omitted, and the cylinder can be hydraulically operated. A cylinder can be adopted, and an actuator such as a motor or air can be used. The supply mechanism, the fastening mechanism, and the like may be provided on one side, three or more, or on the left and right without providing them on the top and bottom. When provided on the left and right, the work or the like is pulled up or down. In addition,
The plurality of supply mechanisms and the fastening mechanism can be different from each other.
