Description

[Detailed description of the invention] This invention is based on a device that automatically attaches a wide single-sided adhesive film to a fixed length plate such as stainless steel plate or plywood that is continuously supplied at regular intervals. The present invention relates to a device that automatically cuts the film at a portion between the front and rear plates without stopping the movement of the plate upon receiving the plate that has advanced.

Conventionally, cutting devices for this purpose include devices that cut the film across the film while rotating a disc-shaped blade, and devices that cut the film by running - non-rotating blades from one end of the film to the other. Alternatively, there is a device that applies a voltage to a heating wire stretched across it to generate heat and press it against the film to cut it.

There is also a method of manually cutting with a knife.

However, with devices that cut with a disk-shaped blade or a single non-rotating blade, the blade cuts while moving from one side of the film to the other, so it takes time to cut, and the same applies to manual cutting. It takes time.

In addition, devices using heating wires have the advantage of being able to cut across the entire length of the film in an instant, so the cutting time is extremely short, but there is a problem in that harmful gases may be generated during cutting depending on the material of the film.

In order to solve the above-mentioned problems, this invention uses a flexible endless knife, supports it with a support ring so that it spans the film's gold mines, and moves the knife at high speed to span the film's gold mines. To provide a cutting device that cuts in an extremely short time while the blade travels a short distance.

The details of this invention will be explained below based on the attached drawings.

In FIGS. 1 and 2, 1 is a frame, and 2 is a pair of left and right guide rails supported by front and rear support stands 3 fixed to both sides of the frame 1.

Reference numeral 4 denotes a movable base mounted to move along the guide rail 2, and is automatically moved forward and backward by a drive mechanism such as a suitable feed screw or a feed chino.

Reference numeral 5 designates a plurality of guide rollers whose shafts at both ends are supported on a plurality of stands 6 provided on both sides of the movable table 4 to freely rotate.

Reference numeral 7 denotes vertical guide columns fixed to the front and back on both sides of the movable table 4, and an elevating frame 8 is attached to each guide column so as to be able to rise and fall freely.

Slightly inclined rotating shafts 10 are rotatably attached to machine boxes 9 at both ends of the elevating frame 8, and support wheels 11 are respectively fixed onto these rotating shafts 10.

In FIGS. 1 to 3, reference numeral 12 denotes an endless knife, in this case in the form of a band, with folded portions at both ends extending over a support ring 11, and a cutting edge 13 extending over the entire length at the lower edge.

In this case, the support ring 11 is provided with a flange as shown in FIG. 3 to prevent the blade 12 from coming off.

Further, the elevating table 8 moves up and down in synchronization with the movable table 4, and in one machine box 9, a shaft 10 is driven to drive a cutter 12.
A drive device is provided to make the volume constant in the direction of the arrow in FIG.

In the above embodiment, in the film adhesive section, the plate 15 with the film 14 pasted on the upper surface is moved onto the guide roller 5 by the roller conveyor A, and the rear end and the next plate 15 are moved onto the guide roller 5 by the roller conveyor A.
When the gap between the tips of the blade 12 reaches just below the working side of the blade 12 in the raised position as shown by the solid line in FIG.
begins to move in the same direction at the same speed as the moving speed of the plate 15.

At the same time, the elevating frame 8 begins to descend, so that the cutting edge 13 of the cutter 12 running towards the middle of the operation is exposed to the film 14 as shown in FIG.
The film 14 is cut across the gold mine in a short time.

Next, the elevating frame 8 rises to raise the cutter 12 onto the film 14, and then the movable table 4 returns to its original position, and the plate 15 separated by cutting the film 14 is taken up by a roller conveyor B.

FIGS. 4 and 5 show another example of an endless cutter, in which a cutter 17 is fixed at regular intervals to a link on one side of an endless chino 16, and in this case, the support wheel 11 is a sprocket.

In addition, in the case of the cutlery in this example, other structures and functions are
This is similar to the example shown in FIG.

In the example shown in FIG. 6, the cutter 17 fixed to a link on one side of the unauthorized chino 16 is oriented in the direction of rotation of the chino 16.

In this case, the support wheel 11 is a sprocket, the rotating shaft 10 is oriented horizontally, and the blade 17 is hung on the support wheel 11 so as to face outward, so that the cutting edge on the working side faces downward.

The structure and operation of other parts are similar to the examples shown in FIGS. 1 and 2.

Furthermore, when the knife 12 is held horizontally as shown in Figure 1, the knife touches the film 14 at the same time, but if the knife 12 is tilted slightly downward to the left in Figure 1, the film will be cut from one side. Sharpness improves.

As described above, this idea leaves an imprint on the film while traveling at high speed with an endless knife spanning the gold mines of the film, the L, and the metal.

Therefore, the film can be cut in an extremely short period of time before the knife reaches the gold mine, a clean straight cut surface can be obtained, and there is no risk of deterioration of the working environment.

Furthermore, since the cutting is done in a very short time, the distance that the plate moves during cutting is also very short, so the amount of movement of the blade when cutting is also very small, making it possible to perform high-speed continuous work.
