Description

Adhesive coating apparatus of polystyrene sheet adhesive

The present invention relates to a polystyrene sheet gluer that heat-bonds a plurality of polystyrene sheets and then adheres paper to both sides in the process of transferring the heat-sealed sheet, and more specifically, temporarily stops work for maintenance of the polystyrene sheet gluer. In addition, the present invention relates to an adhesive applying device for a polystyrene sheet adhesive, by idling the adhesive applying roller while continuously supplying and draining the adhesive even when the operation is completed.

Generally, polystyrene is shipped in the form of a roll on bobbins in the state of primary foaming, and the sheet shipped is thin so that it can be used for stationery, such as the back plate of a frame or the inside of an album cover. Since there is no use, a plurality of sheets are heat-sealed to have a predetermined thickness according to the use thereof, and then cut into a predetermined size.

The sheet is light in weight when printed on the attached paper by attaching paper on both sides, so it is widely used in advertising panels, commercial graphic displays, photo and painting sites, model making, exhibition panels, stage backdrops, and visual devices. It is being used and the demand is increasing.

FIG. 1 is a block diagram showing a conventional polystyrene sheet adhesive machine. The sheet supply unit 2 hangs according to the number of sheets to be fused in a roll form, and a plurality of sheets supplied from the sheet supply unit. A sheet aligning portion 3 for aligning overlapping with the same width, a first heating portion 4 for heating two sheets of adhesive surfaces conveyed in a state aligned evenly from the sheet aligning portion, and the first Secondly heating the two sheets firstly heated from the heating portion, or heat-sealing the second heating portion 5 to be temporarily bonded, and the first and second heating sheets from the first and second heating portions Or an adhesive part 6 for heat-sealing at one time by heating a sheet to which two sheets are bonded and another sheet adhesive surface, and a molding part 7 for secondary foaming of the sheet heat-sealed by the adhesive part; Both sides of the sheet secondary foamed to a predetermined thickness by the molding portion While passing through the paper adhesive portion (9) for adhering the paper (8) to the upper and lower parts, the upper and lower paper supply portion (10) (11) and the paper adhesive portion are provided above and below the molding portion to feed the paper to the paper adhesive portion The quench section 12 for quenching the heat remaining between the bonded sheet and the paper, the slow cooling section 13 for gradually cooling when the sheet quenched in the quench section passes, and the paper is bonded by the paper adhesive Edge cutting portion 14 for cutting the edge to the standard in the state, the sending portion 15 for sending out the sheet cut to a predetermined width by the edge cutting portion, and the sheet sent through the sending portion for cutting to a predetermined length It is comprised by the cutting part 16.

The operation of the polystyrene sheet adhesive machine configured as described above is described in detail in a publication previously filed by the applicant and registered in Korean Patent No. 180,711, and thus a detailed description thereof will be omitted and briefly described.

The sheet supplying part 2 is bonded while passing two or three sheets 1 through the first and second heating parts 4 and 5 and the bonding part 6 as necessary, and then a plurality of sheets are bonded. When the paper 8 is fed from the upper and lower paper feeders 10 and 11 to both sides of the sheet while being heated to the both sides of the sheet, the paper 8 is fed to the feeding unit 15 in a state where the paper 8 is bonded. In 16), the sheet to which the paper is bonded by a cutter (not shown) is cut into a predetermined size and packed.

Conventionally, hot melt is applied to one side of the paper (adhesive surface) in a separate process in order to bond the paper 8 to both sides of the sheet 1 by applying heat from the paper adhesive portion 9 as described above. It is dried and used.

However, the hot melt applied to the adhesive surface of the paper 8 has the property that the paper 8 adhered to the sheet 1 absorbs the hot melt when heat is applied between processes, so that the cross section is coated with the paper adhered to the sheet. Because only available art paper or high-quality imports are available, the following problems occur.

First, the thick art paper coated on one side is heat-bonded to the sheet only when heated to about 150 ° C. during the bonding process with the sheet 1 due to the low thermal conductivity, thereby increasing the amount of electricity used by bonding the paper to both sides of the sheet.

Second, when heat of about 80 ° C. was applied to the paper bonded to both sides of the sheet, the bonded paper was peeled off from the sheet.

Third, the price of hot melt applied to the adhesive side of paper was high, which contributed to the rising cost of the finished product.

Fourth, due to the nature of the hot melt, paper other than art paper cannot be used, and various kinds of paper cannot be adhered to both sides of the sheet.

Fifth, even if the cross-section is coated, if the thickness of the paper is thick (250 g / m2 or more), when the hot melt is dried, since the resilience of the paper is greater than the adhesive strength of the hot melt, a problem that the adhered paper falls from the sheet almost occurs. It is not producing.

In view of the above problems, the applicant has developed and registered in Korean Patent No. 1999-29579 an adhesive coating device that can automatically apply an adhesive to both sides of the sheet to be transported while adhering ordinary paper to both sides of the sheet.

FIG. 2 is a schematic view showing a conventional coating apparatus, and FIG. 3 is a block diagram showing an upper and lower adhesive coating unit. The upper and lower adhesive application units 18 and 19 are provided to apply the water-soluble adhesive 17 to both sides, and the upper and lower adhesive application units 18 and 19 are formed by a tank containing the water-soluble adhesive 17. 20 and the pump 25 for supplying the water-soluble adhesive 17 contained in the tank to the upper and lower adhesive applying rollers 23 and 24 through the supply pipes 21 and 22, and the supply pipe 21. The discharge pipe 27 for supplying the water-soluble adhesive supplied through the upper adhesive coating roller 23 and the middle roller 26, and the water-soluble supplied through the supply pipe 22 located in the lower portion of the lower adhesive coating roller 24 A hopper 28 in which the adhesive 17 is contained, and immersed in a water-soluble adhesive in the hopper. It consists of an intermediate roller 29 to bury the water-soluble adhesive on the lower adhesive coating roller 24 while rotating.

The discharge pipe 27 for supplying the water-soluble adhesive 17 supplied through the supply pipe 21 between the upper adhesive applying roller 23 and the intermediate roller 26 is in the form of a pipe and is spaced at a predetermined interval on the bottom of the discharge pipe. The hole 27a for discharging the water-soluble adhesive 17 is formed.

The water-soluble adhesive 17 is supplied onto the supply pipes 21 and 22 for supplying the water-soluble adhesive 17 in the tank 20 between the upper and lower adhesive applying rollers 23 and 24 and the intermediate rollers 26 and 29. Valves 30 and 31 are provided to control the supply of water, and the outer circumferential surface of the tank 20 in which the water-soluble adhesive 17 is contained is a heater for heating the water-soluble adhesive 17 to room temperature in winter or the like when the temperature of the outside air is low ( 32).

In addition, one side of the paper adhesive portion 9 provided on one side of the upper and lower adhesive coating portions 18, 19 is dried on the adhesive after the paper 8 is adhered to both sides of the sheet 1 at the paper adhesive portion, respectively. A mold part 33 is provided to correct it by being heated to about 70 ° C., which is lower than the temperature, so as not to be deformed. ) Is installed in multiple stages.

Accordingly, the pump 25 in the tank 20 is driven while the sheets 1 of the plurality of sheets 1 are heat-sealed in the adhesive part 6 and then transferred to the paper adhesive part 9 to supply the water-soluble adhesive 17 contained in the tank. When the feed through the discharge tube 27 and the hopper 28 through the 21 and 22, respectively, the intermediate rollers 26 and 29 are in contact with the upper and lower adhesive application rollers 23 and 24, respectively. Since it is rotated, the water-soluble adhesive 17 is buried in the upper and lower adhesive application rollers 23 and 24.

When the water-soluble adhesive 17 is applied to the upper surface of the sheet 1 by the above-described operation, the water-soluble adhesive is rotated while the intermediate roller 29 in the hopper 28 is locked in the water-soluble adhesive 17. Since it is buried in the application roller 24, the water-soluble adhesive 17 is uniformly applied to the bottom surface of the sheet 1, and is transferred to the paper bonding portion 9 side.

In this state, when the paper 8, which is not coated with the adhesive on the adhesive surface with the sheet 1, from the upper and lower paper supply parts 10 and 11, is supplied between the rollers 35 of the paper adhesive part 9, the paper is separated into one sheet. Since the pair of rollers 35 are pressed on both sides of the sheet 1 to which the water-soluble adhesive 17 is applied, the paper 8 is pressure-bonded to both sides of the sheet 1.

In this way, when the paper 8 is continuously adhered to the sheet 1 and reaches the side of the shaping part 33, a heater (not shown) is provided inside the roller 36 of the shaping part 33. Since the roller 36 is heated to about 70 ° C., the paper 8 adhered to both sides of the sheet 1 is preliminarily dried in a flat state while passing between the plurality of rollers.

After that, when the sheet 1 is continuously conveyed and reaches the drying unit provided in multiple stages, the sheet 1 is heated to about 80 ° C. slightly higher than the shaping unit 33 in the first drying unit 34a and then in the second drying unit 34b. The water-soluble adhesive applied to the sheet 1 is completely dried by heating at about 90 ° C, about 100 ° C in the third drying part 34c, and about 110 ° C in the fourth drying part 34d.

However, such a conventional adhesive coating device is a relatively inexpensive water-soluble adhesive on both sides of the sheet by applying a polysol or acrylic resin to adhere to the general paper to produce a variety of sheets, as well as a water-soluble adhesive at a much lower price than hot melt It is possible to reduce the cost according to the production of sheet, but in the process of adhering the sheet and paper, temporarily driving the machine or finishing work, the upper adhesive coating roller and intermediate It was inefficient because the adhesive that had been supplied between the rollers and into the hopper was completely drained to the tank side and then cleaned to remove the upper and lower adhesive application rollers, the intermediate roller, and the adhesive on the hopper.

In addition, the conventional adhesive application portion is fixedly installed in the main body, there is also a problem that maintenance work, work for removing the adhesive is very cumbersome.

The present invention has been made to solve such a conventional problem, and the object is to prevent the adhesive from solidifying without draining the adhesive in the adhesive coating portion to the tank even when the driving of the device is stopped.

Another object of the present invention is to install a detachable adhesive coating in the main body to facilitate maintenance as well as maintenance.

According to an aspect of the present invention for achieving the above object, a polystyrene is provided on the upper and lower adhesive coating portion is installed on the conveying path of the sheet conveyed in the state of the plurality of sheets heat-sealed in the adhesive portion to apply a water-soluble adhesive on both sides of the sheet In the sheet gluer, a pair of guide rods fixedly fixed to the support frame of the upper and lower adhesive applying units, upper and lower mounting plates each of which upper and lower adhesive applying rollers and middle rollers are installed to be elevated on the guide rods, A cylinder fixed to the upper mounting plate and a rod fixed to the lower mounting plate, upper and lower stoppers fixed to the guide rod to control the raising and lowering of the lower mounting plate according to the driving of the cylinder, and perpendicular to the support frame.

The upper and lower adhesive application rollers 23 and 24 are axially fixed directly to the upper and lower mounting plates 38 and 39, but the middle rollers 26 and 29 are upper and lower mountings as shown in FIG. The plates 38 and 39 are coupled to one end of the link 41 pivoting about the shaft 40 by a bearing 42, and the other end of the link is provided with upper and lower mounting plates 38 and 39. The adjustment bolt 43, which is fitted to be idling, is screwed on.

This controls the amount of adhesive applied to the upper and lower adhesive application rollers 23 and 24 by adjusting the distance between the upper and lower adhesive application rollers 23 and 24 and the intermediate rollers 26 and 29. For sake.

In addition, the cylinder 44 is fixed to the upper mounting plate 38, the rod 44a of the cylinder is fixed to the lower mounting plate 39, and the upper and lower mounting plates 38 and 39 are liftable. Upper and lower stoppers 45 and 46 are fixed to the fitted guide rod 37 to control the raising and lowering of the lower mounting plate 39 in accordance with the driving of the cylinder 44.

On the other hand, one side of the support frame 36 is provided with a rotating shaft 47 vertically, as shown in Figure 6 and a driving means 48, such as a motor, is installed on the upper portion of the support frame, the shaft and the rotating shaft of the drive means Bevel gears 49 and 50 are installed in engagement with each other, and the rotating shaft 47 is configured to rotate in accordance with the driving of the driving means 48.

The drive gears 51 and 52 are fixed to the upper and lower portions of the rotating shaft 47 rotating according to the driving means 48, and the upper and lower adhesive application rollers 23 and 24 have cylinders 44. As the upper and lower adhesive application rollers 23 and 24 are positioned at the upper and lower dead centers by driving the upper and lower adhesive application rollers, the upper and lower adhesive application rollers 23 and 24 rotate to engage with the drive gears 51 and 52. Helical gears 53 and 54 are fixed.

Coil springs 55 and 56 are installed on upper and lower portions of the drive gears 51 and 52 which are installed to be engaged with the helical gears 53 and 54 on the rotation shaft 47. Helical gear due to the upper and lower adhesive application rollers 23 and 24 are positioned at the upper and lower dead centers and suddenly engages when the helical gears 53 and 54 are engaged with the driving gears 51 and 52. This is to prevent the breakage of the 53 and 54 or the driving gears 51 and 52 in advance.

On the other hand, the rail 58 is provided on the upper surface of the main body 57, and a plurality of wheels 59 mounted on the rails are installed at the lower portion of the support frame 36 installed on the main body, so that the adhesive applying portion is formed on the main body ( In the state set in the 57, the support frame 36 is fixed to the main body 57 by the bolt 61 using the fixing block 60 so that the support frame 36 does not flow.

As described above, when the adhesive applying part detachably installed from the main body 57 is detached from the main body 57, the fixing block 60 is separated from the support frame 36 located on the opposite side of the pull-out side of the adhesive applying part. As shown by the dashed-dotted line at 4, a separate auxiliary rail 62 is installed on one side of the main body 57 to match the rail 58, and then the adhesive coating part is drawn out of the main body 57 to replace the parts, or It is configured to perform cleaning work to remove adhesive.

Referring to the operation of the present invention configured as described above are as follows.

First, the process of applying the adhesive to both sides of the sheet by the upper and lower adhesive application rollers 23 and 24 in the process of transferring the plurality of sheets of heat-sealed sheet 1 is previously applied and registered by the applicant (application number 1999-29579) and the same description thereof will be omitted.

As described above, in the process of applying the adhesive on both sides of the sheet 1, the rod 44a of the cylinder 44 is pulled as much as possible, so that the upper and lower mounting plates 38 and 39 are close to each other as shown in FIG. Since the mounting plate 39 is in close contact with the upper stopper 45 and the power supply of the driving means 48 is turned off and the rotating shaft 47 is not rotated, the driving gears 51 and 52 provided on the rotating shaft The helical gears 53 and 54 fixed to the lower adhesive application rollers 23 and 24 are kept spaced apart from each other as shown in FIG. 7A.

In such a state, when the device is temporarily stopped for maintenance, or when the device is to be stopped by completing a day's work, the rotating shaft 47 is rotated by applying power to the driving means 48. At the same time, when the rod 44a is pulled out as much as possible by applying pneumatic pressure to the cylinder 44, only the lower mounting plate 39 fixed to the rod descends while the upper mounting plate 38 is stopped.

Accordingly, the lower mounting plate 39 reaches the bottom dead center of the stopper 46 fixed to the lower portion of the guide rod 37. In this state, the pneumatic pressure is continuously applied to the cylinder 44, thereby providing a rod 44a. ), The upper mounting plate 38, on which the cylinder 44 is installed, rises to the top dead center along the guide rod 37, and then the driving of the cylinder 44 is stopped.

That is, the upper and lower adhesive application rollers 23 and 24 are spaced apart from the sheet without removing the sheet 1 from the adhesive.

When the upper and lower mounting plates 38 and 39 rise to the top dead center and the bottom dead center by the above-described operation, the upper and lower mounting plates 38 and 39 are applied to the upper and lower adhesive applying rollers 23 and 24. Since the helical gears 53 and 54 are fixed to one side of the upper and lower adhesive applying rollers, the helical gears are engaged with the driving gears 51 and 52 installed on the rotary shaft 47. The upper and lower adhesive application rollers 23 and 24 are idling in a state where the upper and lower mounting plates 38 and 39 are located at the top dead center and the bottom dead center.

Thus, even while the upper and lower adhesive application rollers 23 and 24 are idling, the adhesive 17 is driven by the pump 25 between the upper adhesive application roller 23 and the middle roller 26 and the hopper 28. Since it is continuously supplied to the inside of the tank and drained to the tank side, the phenomenon that the adhesive solidifies without removing the adhesive from the adhesive coating part is prevented in advance.

On the other hand, in the case of maintenance due to the failure of the components constituting the adhesive coating, or to remove the adhesive, as shown by the dashed line in Figure 4 fixed block from the support frame 36 located on the opposite side of the pull-out side of the adhesive coating After separating the 60 and installing a separate auxiliary rail 62 in accordance with the rail 58 on one side of the main body 57, and replace the broken parts by drawing the adhesive coating to the outside of the main body 57, Cleaning can be done to remove the adhesive.

As described above, the present invention temporarily stops the operation of the device in the process of bonding the paper to both sides of the sheet, or in the state in which the upper and lower adhesive application rollers are spaced apart from each other in the state of completing the work of the day. By rotating the upper and lower adhesive coating roller by the idler is a very useful design that does not need to clean the adhesive coating.

In addition, since the adhesive coating portion can be detachably configured to be taken out of the device as needed, there is an effect that the maintenance of the adhesive coating portion and the removal of the adhesive become very convenient.
