Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to the use of spacing pasteboards, which are components of corrugated paper, laminated batteries, laminated heat exchangers, etc. The present invention relates to an apparatus for manufacturing a spacer plate made up of 4 force-1 units Uζ.

[Prior Art] The spacing plate having the above-mentioned structure is also called a separator or the like and has been a component of various laminated structure articles. Although the material differs depending on the article to which it is applied, its structure is one in which ribs or protrusions made of resin are formed in a row of teeth on one side of a flat plate material, which can be called a film or sheet, to hold space when laminated. Conventionally, such spacing plates have been manufactured using apparatuses and methods disclosed in Japanese Patent Application Laid-open No. 57-205966 and Japanese Patent Application Laid-Open No. 54-7243. In other words, they have been manufactured by heat-sealing resin monofilaments that form the ribs onto a flat plate material, or by linearly applying a highly viscous adhesive resin to a flat plate material to harden it. . The latter is easier to handle continuous manufacturing than the Moesha, so the fourth
Manufacturing using the device shown in the figure has been put into practical use. In other words, a highly viscous adhesive resin is pumped to a plurality of gun nozzles 16 that are arranged in a straight line. The resin is caused to flow down onto the flat plate 17 and harden by moving the flat plate 17 in the direction shown in FIG. It can be formed.

[Problems to be Solved by the Invention] It is difficult to continuously form ribs with the method and apparatus disclosed in Japanese Patent Application Laid-open No. 57-205966 as the prior art described above. On the other hand, according to the conventional technique shown in FIG. 4, it is possible to form the ribs 18 continuously to some extent, but minute fluctuations in the amount of resin discharged from the gun nozzle 16 change the cross-sectional shape of the ribs 18. Not only is it difficult to obtain ribs 18 with constant dimensions and shape, but also
Since the shape of the rib 18 depends on the surface tension of the resin, it becomes a semi-cylindrical shape, and the required height of the rib 18 does not allow the viscosity of the resin to be increased arbitrarily.
There is a problem that it is difficult to obtain #J even if there are many. Furthermore, when the resin being discharged is subjected to the vibrations of the device and the effects of air flow, the rib 1
8 may be meandering, so the pitch of the ribs 18 is also 1.
There are also problems such as not being able to maintain the level of control.

This invention has been made to solve these conventional problems, so that the size and shape of the resin ribs are stable, there is a high degree of freedom in setting the shape, and the resin ribs are provided with an adhesive layer necessary for lamination. The object of the present invention is to provide a spacing plate manufacturing apparatus that can continuously form high-quality spacing plates at high speed.

[Means for Solving the Problems] A spacer plate manufacturing apparatus according to the present invention includes a transfer roller having a plurality of annular forming grooves formed in the circumferential direction and having a predetermined cross-sectional shape on the outer periphery; A nozzle supplies molten resin of Hola 1 to melt type to the annular molding groove of the roller (A fat supply device and the resin-supplied outer circumferential surface of the transfer roller feed the transfer paper at a predetermined speed. A second transfer unit having a configuration similar to that of the transfer roller described above, which forms an adhesive layer of a low melting point adhesive on each top end of double rows of resin ribs formed on one side of the transfer base paper by a base paper supply device and a transfer roller. The adhesive layer transfer device has a roller.

[Function] In this invention, a plurality of annular molding grooves formed in the circumferential direction of the transfer roller and having a predetermined cross-sectional shape are filled with molten resin that will become the resin ribs, and the dimensions and shape of the grooves are constrained.
Transfer base paper is fed to the outer peripheral surface of the transfer roller by a base paper supply device at a predetermined speed, and a double row of resin ribs corresponding to the size and shape of the annular forming groove is continuously formed on one side of the transfer base paper. The adhesive layer of the adhesive necessary for laminating the spacer plates can be continuously formed on the top end of each molded resin rib by transfer, similar to the resin ribs.

[Embodiment] Fig. 1 shows a spacer board as an embodiment of the present invention; B! -Senjusei 4k1
The 01st device forms resin ribs by thermal fusion or by discharging and flowing resin, and the latter can be called a flowing method. It forms a transfer base paper (it does not necessarily refer to paper, but is a general term for thin, low-rigidity paper-like flat plate materials) by transfer, and in this sense it is called a transfer-type m-board manufacturing equipment. It is something that should be done.

The manufacturing apparatus of this example includes a transfer roller 2 having a plurality of annular forming grooves 1 formed in the circumferential direction and having a predetermined cross-sectional shape on the outer periphery, and a hot melt type forming groove 1 in the annular forming groove 1 of the transfer roller 2. a resin supply device 4 that supplies melted 1M fat of the resin through the gun nozzle 3; a base paper supply device 5 that supplies the transfer base paper W at a predetermined speed to the outer peripheral surface of the transfer roller 2 supplied with resin; An adhesive layer transfer device 8 is provided for forming an adhesive layer 7 made of a low melting point adhesive on each top end of the double rows of resin ribs 6 formed by the transfer roller 2 by transfer.

In the figure, the transfer roller 2 is horizontally supported and rotated in a fixed direction by a motor via a speed reducer. The transfer roller 2 has double rows of annular forming grooves 1 continuous in the circumferential direction on its outer periphery at predetermined intervals in the center line direction. The molding groove 1 is the resin rib 6 to be formed.
It is formed to have a cross-sectional shape and dimensions that match the cross-sectional shape and dimensions of. In other words, there is no need to take a semicylindrical shape as in the conventional flow-down method, and it is sufficient to select a groove shape that is most suitable for the purpose of spacing plates, etc., and is less prone to burrs, as long as the groove bottom side does not expand. The surface of the annular molding groove 1 is coated with a resin such as tetrafluoroethylene to improve releasability from the resin.

The resin supply device 4 consists of a hot melt applicator 9, a hose and a gun nozzle 3.

A hot melt applicator is a resin melting furnace with a built-in gear pump, and the molten resin is passed through a hose to a gun.
Force feed to nozzle 3. The gear pump pumps out the molten resin in proportion to the rotational speed of the transfer roller 2 using an SCR (rotation control device). The gun nozzle 3 connected to the photomelt applicator 9 with a hose has each annular forming groove 1 on the rotation axis of the transfer roller 2 on the L side of the transfer roller 2.
The molten resin is fixed to the machine frame of the transfer roller 2 in a one-to-one correspondence with each ejection port, and the molten resin that is being pressure-fed is ejected from an adjacent position into an annular molding groove 1 corresponding to each ejection port. In addition,
The resin fed into the hot melt applicator 9 is hot melt type ethylene vinyl acetate with strong adhesive properties, APP (regenerated gas from the production of polypropylene), etc.
It is heated to about 0.degree. to 180.degree. C. and pumped with air pressure.

The base paper supply device 5 has a configuration of a paper feeding section from an unreel that holds a rolled base paper W for transfer to just before the transfer roller 2, a configuration of a transfer section of the transfer roller 2 portion, and a configuration of a transfer section of the transfer roller 2 portion.
It can be roughly divided into the structure of the delivery section in the latter stage. The unreel is moved in a direction perpendicular to the traveling direction of the transfer base paper W by a controller operated by a signal from the shift detection device to center the transfer base paper W. Further, it is possible to prevent the transfer base paper W from being excessively fed due to rotation due to inertia by applying a brake in response to a stop signal. The above deviation detection device is an air type.

The shift of the transfer base paper W in the width direction is detected by a phototube or the like, and the unreel is driven via a controller. The extreme end of the configuration of the paper feeding section is a guide roller 10 provided in front of the gun nozzle 3 provided above the transfer roller 2 with respect to the rotation direction of the transfer roller 2 (clockwise direction in the drawing). This guide roller 10 is disposed within the radius of the transfer roller 2, and brings the transfer base paper W into close contact with the transfer roller 2 together with a presser roller 11 that contacts the lower end of the transfer roller 2, which constitutes a sending section.

The adhesive layer transfer device 8 has the same structure as the part that transfers the resin ribs 6 described above, and is composed of an adhesive allaplicator 12, a hose and gun nozzle 13, and a second transfer roller 14 similar to the transfer roller 2. 7 Adhesive appligator 12
pumps resin as an adhesive to the gun nozzle 13 via a hose. The gun nozzle 13 is horizontally fixed so that each ejection port corresponds one-to-one to the top end of a plurality of resin ribs 6 formed behind the transfer roller 2, and a second transfer roller corresponding to each ejection port is attached to the gun nozzle 13. The pressure-fed adhesive is dropped into the valley grooves 15 of 14 from a nearby position. The second transfer roller 14 is different from the transfer roller 2 in that it presses the transfer base paper W on which the resin ribs 6 have been transferred while meshing with the resin ribs 6 without wrapping a work around it.

Thus, the transfer base paper W held on the unreel is pulled by the rotation of the transfer roller 2, and is tightly wrapped around the transfer portion of the transfer roller 2 without slipping or loosening. Each molding groove 1 of the transfer roller 2 is filled with melt! from the resin supply device 4. Continuously filled with a certain amount of I fat,
Filled with molten resin and molded? The transfer Kawahara M1W continuously comes into close contact with the outer periphery of the transfer roller 2 where the grooves 111 are no longer in the form of grooves, and the resin ribs 6 are continuously formed by transfer onto the transfer base paper W. The molten resin filled in the molding groove 1 is hardened in parallel with the transfer to the transfer base paper W, and the molding groove 1
The resin ribs 6 having the same cross-sectional shape are fixed on one side of the transfer base paper W. The transfer base paper W on which the resin ribs 6 are fixed can already be called a spacing plate, and is successively peeled off from the transfer roller 2 at its lower end and sent rearward. Immediately, the adhesive layer 7 passes through the adhesive layer transfer device 8, and the low melting point adhesive layer 7 is continuously applied to the top ends of the resin ribs 6 molded here in a row to the second transfer roller 14.
(See Figure 2, I9B and C).

The adhesive layer 7 is fixed on the resin rib 6 with a uniform thickness. Then, by cutting them to predetermined dimensions and laminating them as shown in Fig. 3, and melting the adhesive layer 7 to generate adhesive strength, it is possible to make articles such as heat exchangers by laminating the spacer plates. can.

The features of this spacer plate manufacturing device are that the cross-sectional shape of the resin rib 6 can be freely set, its height can be defined by the molding groove 1 without depending on the viscosity of the resin, and the light molten resin is poured into the molding groove 1. It is not subject to disturbance requirements such as airflow or vibration during filling and transfer, and high-precision, high-quality spacing plates can be obtained rapidly and continuously using a small amount of resin material. The rib 6 can be molded to a uniform thickness.

[Effects of the Invention] As is clear from the above description of the embodiments, the spacer plate manufacturing apparatus of the present invention has a plurality of annular molding grooves formed in the circumferential direction and having a predetermined cross-sectional shape on the outer periphery. A transfer roller, a resin supply device that supplies real-melt type molten resin to the annular molding groove of the transfer roller through a nozzle, and a transfer base paper that is applied at a predetermined speed to the outer peripheral surface of the transfer roller to which the resin has been supplied. a second base paper feeder having the same structure as the above-mentioned transfer roller, which forms an adhesive layer of a low melting point adhesive on each top end of double rows of resin ribs formed on one side of the transfer base paper by the transfer roller. An adhesive layer transfer device with a transfer roller and f! - Since the molten resin that will become the resin ribs is filled into a plurality of annular molding grooves formed in the circumferential direction of the transfer roller and having a predetermined cross-sectional shape, the size and shape of the grooves are constrained while the transfer is performed. Transfer base paper is fed to the outer peripheral surface of the roller by a base paper supply device at a predetermined speed, and double rows of resin ribs that match the size and shape of the annular forming groove can be continuously formed on one side of the transfer base paper. The adhesive layer of the adhesive necessary for laminating the spacer plates can be continuously formed to a uniform thickness on the top end of each molded resin rib by transfer, similar to the resin rib. In other words, it is possible to continuously form high-quality spacing plates at high speed that also have the adhesive layer necessary for lamination.
