Description

  The present invention relates to a technique of cutting a decorative sheet made of synthetic resin or paper wound in a roll shape while being attached to each base plate such as a plywood coated with an adhesive.

As a conventional method of pasting a decorative sheet on a base plate, one is that a roll-shaped decorative sheet is extended for a long time, pasted onto a base plate continuously conveyed using a continuous automatic pasting machine, and then subjected to a pressing process. There is a method of cutting (for example, Patent Document 1).
The other is a method in which a decorative sheet is once cut into separate sheets with another equipment and pasted using an automatic sheet pasting machine (for example, Patent Document 4).

However, in the former continuous automatic pasting method, waste of the decorative sheet occurs over several meters at the start and end of winding of the roll. In addition, since it is necessary to continuously convey the base plate by abutting, the control of the conveyance speed is complicated, and even if a problem occurs in the bonding, the production cannot be stopped immediately. I was forced to discharge the defective product.
In addition, in the latter single wafer automatic pasting method, it is a burden to increase the process and the equipment area, and depending on the nature of the decorative sheet, there is a problem in the pasting to the base plate due to the curling habit, which greatly affects the production efficiency. It was happening.

  The present invention is a technique for attaching a decorative sheet on a base plate such as a plywood, and cuts the decorative sheet fed directly from the sheet roll immediately after being attached to the base plate, so that each decorative plate can be efficiently The purpose of this invention is to provide a method for producing single wafers with high efficiency and an apparatus for realizing the production.

  The front end of the decorative sheet fed from the sheet roll in the automatic decorative sheet attaching method in which a decorative sheet made of synthetic resin or paper in a rolled state is attached to a base plate such as a plywood coated with an adhesive After positioning and sandwiching the tip of the base plate supplied to the sheet, the feeding roller attaches and bonds the decorative sheet from the front end of the base plate to the rear end, and simultaneously cuts the decorative sheet at the rear end of the base plate. By positioning and holding the tip of the next decorative sheet, it was possible to produce sheets according to the loading of the base plate.

  As a device for realizing this method, a device for holding and cutting the front end of the decorative sheet is provided at the decorative sheet sticking portion, and a device for stopping the base plate and aligning with the front end of the decorative sheet is arranged and synchronized. The present invention has invented a sheet-fitting automatic sheet-fitting device comprising a structure that cuts a decorative sheet while rotating, and an air discharge roller and a press roller that rotate in synchronization with the decorative sheet attaching part.

  According to the present invention, the product type can be changed in a short time from the state in which the decorative sheet roll is placed at the installation position to the time when the decorative sheet roll is sandwiched between the rollers that hold the front end of the decorative sheet, and Since it is possible to automatically complete from the pasting to the press after being introduced in step 1, there is an effect that the decorative board can be produced efficiently without depending on the transport request of the front and rear devices.

Side view of a decorative sheet sheet automatic pasting device according to the present invention. Front view of Fig. 1 Explanatory drawing of the decorative sheet sheet automatic sticking method according to the present invention.

  A side view of the apparatus of the present invention is shown in FIG. 1, and a front view is shown in FIG. There is a cutter roller 6 having a sufficient width with respect to the width of the decorative sheet, and a stopper roller 8 having a base plate stopper 9, which rotate in synchronization with each other. A cutter 7 that travels is provided inside the cutter roller 6 having an opening, and the rotation of the cutter roller 6 and the traveling of the cutter 7 can be operated simultaneously. The cutter roller 6 is moved up and down by the lifting device 10 to follow the thickness of the base plate, and also moves up and down when the decorative sheet is sandwiched and released. Similarly, the stopper roller 8 has an opening, and the base plate stopper 9 is driven by air or the like so as to enter and exit from the surface of the stopper roller. On the downstream side of the cutter roller 6, there are a first roller 11 that discharges air between the laminated decorative sheet and the base plate, and a second roller 12 that performs press bonding, and all these rollers maintain the same speed. It is desirable to be driven by a servo motor or the like. In addition, a table 1 for holding a decorative sheet roll is provided above. This is equipped with a brake to suppress the inertia caused by the rotation of the roll. This is even better if the structure is such that a plurality of cradles are switched so that the roll types can be easily exchanged.

  An embodiment of an automatic sticking apparatus using the automatic sticking method of the present invention will be described. As shown in FIG. 3A, the decorative sheet wound in a roll shape is sandwiched between base plate stoppers 9 provided on the cutter roller 6 and the stopper roller 8, and the leading end of the bonding is positioned. At this time, the gap between the cutter roller 6 and the stopper roller 8 is slightly larger than the thickness of the base plate. The cutter 7 is stopped at one shaft end of the cutter roller 6 at a position where it does not interfere with the base plate width. FIG. 3 (3) shows a state in which the cutter roller 6 and the stopper roller 8 sandwich the base plate after the base plate is positioned by contacting the base plate stopper 9 as shown in FIG. 3 (2). Since the base plate stopper 9 can be lowered by an external force, the cutter roller 6 can be lowered while pushing down the base plate stopper 9 to sandwich the decorative sheet and the base plate together.

  Thereafter, the cutter roller 6 and the stopper roller 8 start synchronous rotation as shown in FIG. Thereafter, the base plate stopper 9 is pulled in and fed to the position of the first roller 11 in a state where the base plate and the decorative sheet are bonded together, and then the cutter roller 6 rises to a height at which it does not contact the decorative sheet. It becomes FIG. 3 (5). The stopper roller 8 also stops rotating at an angular position where its own roll surface opening does not come into contact with the base plate, so that the state shown in FIG.

  Eventually, after detecting the rear end position of the base plate with the sensor as shown in FIG. 3 (7), the cutter roller 6 and the stopper roller 8 rotate while synchronizing based on the calculated position through which the rear end of the base plate passes. The base plate stopper 9 is raised again at a position where the base plate stopper 9 with respect to the next base plate can be moved up and down. Since this base plate stopper 9 also has a function of holding the decorative sheet between the cutter rollers 6, immediately after the holding, the cutter 7 in the cutter roller 6 runs on the opposite side of the roller axis direction and holds the decorative sheet. Cut. At this time, the cutter roller 6 and the stopper roller 8 are rotating. After cutting, the cutter roller 6 and the stopper roller 8 stop rotating at the position shown in FIG. Thereafter, this operation is repeated for each sheet.

  The present invention minimizes the waste of the decorative sheet roll, suppresses the defective rate of the product, and also reduces the number of procedures at the time of product replacement, enabling efficient production from a single decorative plate, In the production of decorative boards for a wide variety of products, a great demand in the industry can be expected.
