Description

Panel manufacturing system with improved productivity {High productive panel manufacturing system}

The present invention relates to a panel manufacturing system with improved productivity, and more specifically, to a panel manufacturing system with improved productivity that enables the operation of continuously foaming urethane, etc. in a panel with a simple structure, thereby minimizing dead time. will be.

In general, a sandwich panel is a building panel material manufactured to provide insulation or waterproofing by embedding a filler such as expanded urethane or urethane foam in a panel case made of steel plate. An example of a device that manufactures such sandwich panels is a device that can be used by workers. An assembly workbench for assembling panel cases or holding pre-fabricated panel cases, a loading die for stacking panel cases transferred from this assembly workbench in multiple stages, and a state on which panel cases supplied from this loading die are placed. It is composed of a filling die that injects filler such as urethane foam into the panel case by means of a foaming device.

In this conventional panel manufacturing device, the loading die is equipped with a stand for loading the panel cases in multiple stages, and even or odd groups of these stands are operated at the same time to supply the panel case onto the charging die or to load the panel case on the charging die. It is designed to pull out the completed panel, and on this loading die, it is equipped with a lifting device for up and down movement, such as a power base and up cylinder, a roller mechanism and an automatic control device to operate and control the even and odd units alternately.

In addition, a press device is provided on the filling die to press and support the panel case during the foaming process of injecting the foaming liquid into the panel case. This press device is provided with a multi-stage pressure plate that simply presses the panel case or a press device that presses the panel case. It can be provided as a hot press device equipped with a hot plate that generates heat when heated.

Sandwich panels produced in this way are convenient for transportation and installation during construction work, but due to the nature of the filler foam injected into the panel case, there is a problem that it is easy to ignite and spread in the event of a fire, and in recent years, these problems have been introduced. In order to improve this, the production regulations for sandwich panels require the addition of flame retardant materials to produce fillers.

Therefore, in the future, according to the above-mentioned manufacturing method, there will be a problem that the foaming time takes longer due to the addition of flame retardant, but the conventional panel manufacturing device has to cope with the waiting time of the device due to the longer foaming time. There is a problem in that the productivity of manufacturing panels is low in that a device system that can perform other foaming operations has not been established.

As shown in Figures 3 and 4, the lift work table 30 is a lift work table 30 for assembling the panel case 11 as described above or holding the pre-assembled panel case 11 by the operator. This lift work table 30 is equipped to adjust the height of the work table 31 by using a cylinder 32 and a link 35, and at the same time, a transfer roller 33 and a feeding roller are installed on the work table 31. 34) is provided so that the panel case 11 can be easily delivered to the loading device 40.

In addition, the loading device 40 is provided with a loading body 42 capable of loading the panel cases 11 in multiple stages, and a plurality of trays for holding the panel cases 11 on the loading body 42 ( 43) is provided up and down, and a feeding roller 44 and a guide roller 45 are installed on both sides in the width direction of the loading body 42. The feeding roller 44 is a motor ( 48) and is driven in a state of pressurization and close contact with both sides of the tray 43 by the cylinder 49, etc., and the tray 43 itself is mounted on the panel case 11 and press device 60. ) proceeds directly to the side and delivers the panel case (11).

In addition, the press device 60 is equipped with a plurality of press bars 64 capable of holding the panel case 11 on the press body 63, and includes press means for pressing the press bars 64 ( 65) is located at the top, and the pressurizing means 65 consists of a pressurizing cylinder 67 operated while connected to a hydraulic mechanism 66, etc., and a main pressurizing plate 68 operated by the pressurizing cylinder 67. When the uppermost panel case 11 is pressed by the main pressure plate 68, each of the press bars 64 moves downward in series, causing each panel case 11 to be brought into contact with the bottom of the upper press bar 64. A pressurizing operation is performed.

Each of these press bars 64 is lifted and lowered while maintaining a constant vertical distance by the guide rod 69, and the tray 43 is placed on the press bar 64 while holding the panel case 11. It is seated, and a feeding roller 70 is installed on one side of the press body 63 for inserting or unloading the tray 43, and a moving wheel 46 capable of rolling movement is mounted on the bottom of the tray 43.
