Description

[Detailed description of the invention] Technical field This invention relates to a honeycomb core expansion and curing equipment used for honeycomb cores such as wall panels.

BACKGROUND ART Conventionally, paper honeycomb cores impregnated with resin and reinforced have been used in wall panels and floor panels. This honeycomb core is made by partially overlapping pieces of paper with an adhesive and then stretching them. The paper strip is impregnated with resin and left in a semi-dry state, and must be completely cured after being stretched. However, when the expanded honeycomb core is transported to a drying oven or for natural drying, there is a lot of wasteful handling and efficiency is desired.

Purpose of the invention The purpose of this invention is to provide honeycomb core expansion and curing equipment that can efficiently carry out the process from the expansion of the honeycomb core to the end of drying and curing.

DISCLOSURE OF THE INVENTION The honeycomb core stretching and curing equipment of this invention is equipped with a stretching machine and a carry-out conveyor for transporting the honeycomb cores from the stretching machine to the trolley on one side of the rail of the trolley that carries the honeycomb cores into the drying furnace, and on the other side A curing conveyor for natural drying and a jig return conveyor for returning the transport jig from the end of the curing conveyor are arranged side by side.

Embodiment An embodiment of this invention is shown in FIGS. 1 and 2. In the figure, 1 is a stretching machine that expands an unexpanded honeycomb core.
is provided. The carry-out conveyor 2 conveys the upwardly U-shaped carrying jig 4 on which the honeycomb cores 3 are loaded, and is composed of a roller conveyor. A frame 5 is provided above the spreading machine 1 and the unloading conveyor 2, and a loading machine 6 is installed on the frame 5 to grasp the honeycomb core 3 on the expanding machine 1 and load it onto the carrying jig 4 of the unloading conveyor 2. It is set up so that it can be moved freely.

A truck rail 7 is provided extending perpendicularly from the terminal end of the discharge conveyor 2, and a truck 8 is provided on the truck rail 7. A drying oven 9 is provided on one side of the truck rail 7, and a curing conveyor 10 and a jig return conveyor 11 are also provided. The drying oven 9 has an internal conveyor 12 . The jig return conveyor 11 is provided at a terminal extension position of the carry-out conveyor 2, and the curing conveyor 10 is provided parallel to it. The curing conveyor 10 and the jig return conveyor 11 are non-powered roller conveyors, and have inclinations in opposite directions. A lifting platform device 1 is provided at the end of the curing conveyor 10 and the start end of the jig return conveyor 11.
3 and 14 are provided. A product take-out conveyor 15 is provided laterally from the terminal end of the curing conveyor 10, and a cutting workbench 16 and a product take-out conveyor 17 are further provided.

Operation: Load the unexpanded honeycomb core into the expanding machine 1 and expand it to a predetermined width. The expanded honeycomb core 3 is loaded onto a transport jig 4 on a carry-out conveyor 2 by a loading machine 6. When a certain number of honeycomb cores 3 have been loaded, the carrying jig 4 loaded with the honeycomb cores 3 is carried out by the carry-out conveyor 2 and placed on a trolley 8 on the trolley rail 7. The trolley 8 is moved to the front of the drying oven 9, and the honeycomb core 3 is moved to the transport jig 4.
The whole product is carried into the drying oven 9 by the in-furnace conveyor 12.
When the honeycomb core 3 is completely dried, it is placed on the cart 8 again and the cart 8 is returned to the starting end of the curing conveyor 10.
Then, the honeycomb core 3 is transferred along with the transport jig 4 to the curing conveyor 10, and while being transported on the curing conveyor 10, the honeycomb core 3 is naturally dried. The curing conveyor 10 can store several transport jigs 4 loaded with honeycomb cores 3. When the end of the curing conveyor 10 is reached, the transport jig 4 is raised by the lifting platform device 13, and the honeycomb core 3 is lifted up by 1.
The products are taken out one by one onto the product take-out conveyor 15. The honeycomb core 3 taken out is carried out from a product carrying-out conveyor 17 via a cutting workbench 16. The empty transport jig 4 on the lifting platform device 13 is transferred to the jig return conveyor 1.
The jig is further lifted up by the lifting platform device 14 at the starting end of step 1 and placed on the jig return conveyor 11.
From there, it passes over the cart 8 and returns to the starting end of the carry-out conveyor 2. In this way, the expanded honeycomb core 3 can be efficiently cured without causing waste such as reloading,
It can be carried out. Furthermore, the empty transport jig 4 can be returned efficiently.

Effects of the invention The honeycomb core spreading and curing equipment of this invention has the effect of efficiently carrying out the process from spreading the honeycomb core to completing drying and curing.
