Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an apparatus for manufacturing a composite metal plate in which two metal plates are bonded to both sides of an intermediate layer of a synthetic resin film by heat fusion.

(Prior Art) In recent years, the demands on the functions of metal plates, that is, metal sheets, have been diversifying, and many products are being developed to satisfy these demands.

For example, by interposing synthetic resin between two thin steel plates and making them composite, even if the thickness is almost the same as that of a single conventional steel plate, it can be made larger without reducing rigidity. There is something called a lightweight steel plate that can significantly reduce weight. This is approximately 0.03 to 0.11 in the middle of two steel plates used for automobile body components, etc.
A so-called distributed steel plate is made by interposing a synthetic resin material of I11 thickness to improve the distribution property, and a composite material is made by combining various combinations of two metal plates of different materials with a synthetic resin material interposed in the middle layer, resulting in corrosion resistance, There are panel materials with improved required functions such as thermal insulation properties, and all of these are in widespread use today.

Conventionally, methods for manufacturing this type of composite metal plate include an adhesive type manufacturing method in which the metal plate is bonded with an adhesive at the interface of the synthetic resin to form a composite, and another method involves bonding the metal plate at the interface with the metal plate using an adhesive. There is a heat-fusion manufacturing method in which synthetic resin is melted and fused.

In addition, both of these composite metal plate manufacturing methods include a cut plate manufacturing method using cut plate-shaped materials and a continuous coil manufacturing method using coiled long materials, which are both highly efficient and cost-effective. This can be achieved by a continuous manufacturing method using coils.

Next, a representative example of a conventional heat-sealing continuous manufacturing method will be described.

For example, in the method disclosed in Japanese Patent Publication No. 54-15703, one metal plate is fed straight from the lateral direction to a pair of heating rolls through a preheating process, but the other metal plate is After the layers have been laminated, a synthetic resin film supplied from a payoff reel above the post-processing equipment for the product in a direction opposite to the flow of the product is further positioned above the payoff reel.

The product is supplied from the uncoiler in the opposite direction to the flow of the product, and is first fused to the other metal plate, then changed direction by the heated roll pair and fused to the one metal plate, thus producing three The layers are laminated together.

After the three layers have been laminated, the finished product undergoes re-heating and pressing, second cooling,
After passing through a post-processing device such as secondary cooling, it is finally wound onto a Tensilon reel.

In the case of this method: (1) It is necessary to install a payoff reel for the other metal plate above the post-processing equipment for the finished product after three-layer lamination, and it is necessary to load the metal coil, which is a heavy object, and to Installing the payoff reel above where bank tension is applied is
This is disadvantageous in terms of the strength of the frame and equipment costs; (2) The uncoiler for synthetic resin film is also located above the product post-processing equipment, which requires a large space, especially in the vertical direction, and may interfere with the overhead crane. (3) Synthetic resin film and metal plate on the other side The longer the distance to the heating roll pair for three-layer lamination after lamination with the
There are problems such as a large loss of cooling heat into the atmosphere, leading to an increase in manufacturing costs.

(Problems to be Solved by the Invention) An object of the present invention is to provide a heat-sealing type continuous manufacturing apparatus for composite metal plates, which improves the problems of the prior art as described above.

(Means for Solving the Problems) Thus, the present inventors incorporated a plurality of heating rolls provided in a three-layer bonding device for metal plate-synthetic resin film-metal plate together, and bonded both metal plates together. It has been discovered that by combining heating and guiding, the bonding device can be made more compact, and the heat loss due to cooling to the atmosphere can be minimized to the limit.

Furthermore, the present inventors reexamined the overall layout of the fusion-type continuous manufacturing equipment for composite metal plates, and found that the payoff reel for both metal plates and the uncoiler for the synthetic resin film were placed upstream of the laminating equipment section. Both the metal plate payoff reels and the tension reel for winding the product can be lined up in a line, and both the metal plate payoff reels and the product winding tension reel, which are heavy and have a large overturning moment due to the back tension of the metal plate, can be mounted on the factory floor. It was discovered that by directly installing it, load conditions such as overturning moment can be relaxed as much as possible, and the foundation work can be done at a lower cost.

Here, the present invention provides: a first payoff reel for unwinding a metal plate; an uncoiler for unwinding a synthetic resin film; heating the metal plate to a temperature higher than the melting temperature of the synthetic resin film; A first roll mechanism consisting of a heating roll and a guide roll that guides the plate and laminates it to the synthetic resin film to form a single-sided composite metal plate; a second payoff reel that unwinds another metal plate; the other metal plate heated to a temperature higher than the melting temperature of the synthetic resin film, and then guides the other metal plate and laminates it to the synthetic resin film of the single-sided composite metal plate to form a composite metal plate, from a heating roll and a guide roll. A second roll structure comprising: a post-processing device for the obtained composite metal sheet; and a tension reel for winding the finally obtained composite metal sheet product; By using the heating roll and guide roll that constitute each of the roll mechanism and the second roll mechanism to reduce the size of the device constituted by the first and second roll mechanisms, the amount of heat radiated to the atmosphere etc. when heating the metal plate is reduced. This is a composite metal plate manufacturing device characterized by reducing loss.

Further, the present invention provides a first payoff reel for unwinding a metal plate; an uncoiler for unwinding a synthetic resin film; heating the metal plate to a temperature higher than the melting temperature of the synthetic resin film; A first roll mechanism consisting of a heating roll and a guide roll that guides and laminates the other metal plate to the synthetic resin film to form a single-sided composite metal plate; A second payoff reel that unwinds the other metal plate; A second metal plate comprising a heating roll and a guide roll, which is heated to a temperature higher than the melting temperature of the synthetic resin film, then guides the other metal plate, and is laminated to the synthetic resin film of the single-sided composite metal plate to form a composite metal plate. a two-roll mechanism; a post-processing device for the obtained composite metal sheet; and a tension reel for winding up the finally obtained composite metal sheet product; and a second payoff reel is provided on the upstream side of the laminating device section consisting of the first roll mechanism and the second roll mechanism, and the first payoff reel, the second payoff reel, the first roll mechanism, and the second roll. The mechanism, post-processing device, and tension reel are installed side by side on the same line, and the above-mentioned first or second payoff reel and tension reel are both installed on the factory floor without a stand, thereby suppressing the overturning moment. This is a composite metal plate manufacturing device that is characterized by low civil engineering costs.

(effect) The accompanying drawings are schematic diagrams illustrating the apparatus of the invention.

In the figure, metal plates 1 and 2 are unwound from metal plate coils 5 and 6 attached to a first payoff reel 3 and a second payoff reel 4, respectively.

On the other hand, the synthetic resin film 7 is unwound from the uncoiler 8. These are bonded together in the bonding device section 9 to form a three-layer composite metal plate. In that case, the synthetic resin film 7 and the gold mud plates 1 and 2 are successively laminated in three layers using heating holes 10, 11, 12, and 13, which also serve to heat the metal plates and guide them to the lamination area. That is, the metal plate from the first payoff reel is heated via a guide roll 12 that also serves as a heating roll, which is provided as desired, and then further heated by a guide roll 10 that also serves as a heating roll and a first-stage pressure roll 14 to form a synthetic resin film. 7 is adhered to form a single-sided composite metal plate. Next, gold N slope 2 from the second payoff reel 4
is heated to a temperature higher than the melting temperature of the synthetic resin film by the guide roll 13 which also serves as a heating roll, which is also provided as desired, to the synthetic resin film side of the above-mentioned single-sided composite metal plate. It is glued. Here, the first stage pressure bonding roll 14 is used for pressing,
An actuator (not shown) is attached so that the intervening single-sided composite metal plate can be rolled down. Also,
The heating roll 11 is also attached with an actuator (not shown) for pressing, so that it can press down the intervening composite metal plate. These heating rolls 10 and 11
Preferably further heating rolls 12 and 13 consisting of
After the three layers are bonded through the bonding device section 9, which includes a bonding device section 9 including
The composite metal sheet product is wound onto a tension reel 18 via a post-processing device including a drying device 17 and the like.

Note that the guide rolls 12.13, which also serve as heating rolls, have the function of reversing the metal plate from the forward direction to the reverse direction of the composite metal plate production line, since the payoff reels 3.4 are both located on the upstream side. By using a heating roll for these as well, additional effects such as uniform heating of the metal plate can be obtained.

As is clear from the illustrated example, the drawbacks of the conventional method have been improved as follows. That is, (1) a plurality of heating rolls that also serve to heat the metal plate and guide it to the bonding area
They are all built into one housing, making it more compact, and at the same time, the contact of the metal plate with the atmosphere after heating is minimized, reducing heat loss. Naturally, it is also possible to attach a heat insulating cover that also serves as a metal plate guide.

(2) The payoff reel for both metal plates and the uncoiler for supplying the synthetic resin film are placed upstream of the laminating device section, and after laminating the three layers, only the product flows through the tension reel. The line structure has been streamlined and the entire line has been made more compact.

(3) For payoff reels and tension reels, which are subject to the weight of the coil and a large overturning moment due to bank tensile force, when mounted on a mount, the overturning moment becomes large and a large foundation is required. Although the frame also needed to be sturdy, according to the present invention, it can be installed directly on the factory floor, thereby significantly reducing equipment costs.

(Effects of the Invention) As explained above, the present invention is an excellent manufacturing apparatus that eliminates the various drawbacks of conventional continuous manufacturing apparatuses for heat-sealing composite metal plates.
