Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for forming an open foam board for heat insulation, which is disposed inside a door, for example.

As shown in FIG. 5, a continuous foam board 1 formed by a continuous foam board molding apparatus includes a pair of upper and lower surface plates 2, 3 with bent side edges 2A, 3A, and a filling material between the both surface plates 2, 3. Both surface plates 2 and 3 are thin and easily damaged. On the other hand, both surface plates 2,
Since there is inevitably some play in the endless tracks of the pair of upper and lower conveyor devices that convey 3, the endless tracks of the upper conveyor device may move unexpectedly at the entrance and exit of the conveyor device, causing damage to the upper surface plate 2. There is a risk of getting it on.

Therefore, the present invention provides an apparatus for forming a continuous foam board that solves these problems.

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 4. 5 and 6 are a pair of upper and lower conveyor devices, each having a frame 7 and 8, a drive shaft 9 and 10 rotatably disposed at one end of the frame 7 and 8, and a drive shaft 9 and 10 rotatably disposed at the other end of the frame 7 and 8. Passive shafts 11 and 12 rotatably arranged, and each shaft 9 to 12
sprocket wheels 13 to 16 disposed in pairs each, chains 17 and 18 with endless rollers 17A and 18A wound between the sprocket wheels 13 to 16 facing each other; Consisting of slat plates 19 and 20 fixed to each link, both upper and lower slat plates 1
A slight gap is formed between 9 and 20. 21
22 is a first drive device that rotates the drive shafts 9 and 10, and 22 is a column provided on both sides of both conveyor devices 5 and 6 at appropriate intervals along the conveying direction A of both conveyor devices 5 and 6. and each pillar 2
2 is constituted by a pair of U-shaped frames 22A. Reference numeral 23 denotes a lower horizontal rod extending horizontally from the frame 8 of the lower conveyor device 6, and is inserted between the two U-shaped frames 22A of each of the above-mentioned supports 22. is fixed to. 24
is an upper horizontal rod extending horizontally from the frame 7 of the upper conveyor device 5, and each of the above-mentioned supports 2
It is inserted between the two U-shaped frames 22A so that it can be raised and lowered. Reference numeral 25 denotes a sliding frame whose central portion is fixed to the tip of each upper horizontal rod 24 and which is arranged to surround the support column 22, and whose both ends are fixed to the frame 7. 26 is a pair of cross beams arranged along the direction of arrow A on each support 22; 27 is each cross beam 2;
The lower end of the threaded rod 28, which is screwed into the screw hole of the worm wheel, is connected to each upper horizontal rod 24 via a connecting rod 29. There is. Further, the worm gears of each worm gear mechanism 27 are connected to each other by an interlocking shaft 30. 31 is a second drive device that rotates the worm gear of the worm gear mechanism 27 on the upstream side in forward and reverse directions;
The worm wheels of each worm gear mechanism 27 are rotated forward and reverse via the interlocking shaft 30, thereby raising and lowering each threaded rod 28, and raising and lowering the upper conveyor device 5 via each connecting rod 29 and each upper horizontal rod 24. It is something. Reference numeral 32 denotes a pair of left and right support devices disposed on the upstream side between both conveyor devices 5 and 6, each supporting a pair of sprocket wheels 3.
3, 34, and both sprocket wheels 33, 3
Endless chain 35 with rubber plate wound between 4
and a third drive device (not shown) that rotates the drive-side sprocket wheel 33. When each chain 35 is synchronized with the conveyor devices 5 and 6 and run in the direction of arrow B, the rubber plate of the chain 35 is rotated. are inserted between the upper and lower slat plates 19, 20 and conveyed by the conveyor devices 5, 6.
This is to prevent both surface plates 2 and 3 from shifting relative to each other. Reference numeral 47 indicates a filling device for filling a foamable synthetic resin material in liquid or powder form between the surface plates 2 and 3, and 48 indicates a guide rail for the rollers 17A and 18A. A foaming device (not shown) for foaming the foamable synthetic resin material between the surface plates 2 and 3 is provided at the locations where both the conveyor devices 5 and 6 are provided. 5
0 is a guide roller rotatably supported by L-shaped plates 51 protruding from both ends of each slat plate 19 of the upper conveyor device 5; 52 is a guide roller whose base end is bolted to the inlet end of the frame 7; A pair of guide frames extending in opposite directions, 53 indicates each guide frame 5.
A guide rod bolted to the bottom of 2,
It is arranged along the tangential direction of the sprocket wheel 15, and supports the guide roller 50 of each slat plate 19 that is trying to move away from the sprocket wheel 15, and prevents each slat plate 19 from sagging or sideways. This prevents it from shaking.

In the above embodiment, only the configuration at the entrance of the upper conveyor device 5 has been described, but a guide rod 53 is also provided at the exit of the upper conveyor device 5 to prevent each slat plate 19 from sagging or rolling.

The operation of the above configuration will be explained. A pair of coiled iron plates are pulled out and both side edges thereof are bent to form surface plates 2 and 3. Next, both surface plates 2 and 3 are inserted between both conveyor devices 5 and 6. Next, both conveyor devices 5 and 6 are operated by the first drive device 21 to cause both slat plates 19 and 20 to travel in the direction of arrow A, thereby conveying both the above-mentioned top plates 2 and 3 in the same direction. . At this time, each slat plate 19 remote from the sprocket wheel 15 at the entrance of the upper conveyor device 5 tends to sag or sway. However, before each slat plate 19 separates from the sprocket wheel 15, the guide roller 50 of that slat plate 19 climbs onto the guide rod 53.
To prevent each slat plate 19 from sagging or rolling. Further, the chain 35 of each support device 32 is moved in the direction of the arrow RO to support both the surface plates 2 and 3 so that they do not shift relative to each other. Next, a foamable synthetic resin material in liquid or powder form is filled between both surface plates 2 and 3 from the nozzle of the filling device 47. In this case, since the lower surface plate 3 serves as a saucer, the synthetic resin material will not leak. Next, when the synthetic resin material is inserted between both the conveyor devices 5 and 6 together with both surface plates 2 and 3, the synthetic resin material is heated and foamed by a foaming device. Then, due to the foaming, both the surface plates 2 and 3 are pressed in a direction away from each other and try to shift position, but as described above, both the surface plates 2 and 3 are held by the chain 35 of each support device 32. so it will not shift position. Next, the foamed continuous foam board 1 is sent out from the rear ends of both conveyor devices 5 and 6.

As described above, according to the continuous foam plate forming apparatus of the present invention, of both conveyor apparatuses that convey a pair of long surface plates in close proximity to each other, guides are provided at both ends of each slat plate of the upper conveyor apparatus. Each slat plate is provided with rollers and a guide rod that supports each slat plate via each guide roller is fixed to the frame of the upper conveyor apparatus at the inlet and/or outlet of the upper conveyor apparatus. will not sag or sway at the entrance or exit, or both, and will not move unexpectedly and strike and damage opposing face plates.
