Description

[Detailed explanation of the idea]

[Industrial Field of Application] The present invention relates to a heating device for molded carpet used for flooring of vehicles such as automobiles. [Prior Art] Carpets used as floor coverings for vehicles such as automobiles are molded into a predetermined shape to match the shape of the floor. For this purpose, a moldable plastic sheet such as a polyethylene sheet is pasted on the back side of the carpet, the plastic sheet is heated and softened, and then placed in a mold and cold pressed. Conventionally, an apparatus as shown in FIG. 5 has been used to heat and soften carpet plastic sheets. In the figure, reference numeral 1 denotes a box-shaped heating furnace with a far-infrared lamp 2 installed therein, and a pair of rails 3 are arranged above both side edges of the heating furnace 1, and a support on which a pin 41 is attached on the rails 3. 4 are slidably arranged in pairs at the front and rear. And plastic sheet 51
The plastic sheet 51 is heated and softened by hooking the four corners of the carpet 5 lined with the plastic sheet 5 to the pins 41 of the support 4 and supporting it on the heating furnace 1.
Thereafter, the carpet 5 is manually pulled in the direction of arrow A in FIG. 5 via the support 4 and set in a mold (not shown). [Problems to be solved by the invention] In the above conventional technology, a gap is created between the top surface of the heating furnace and the back surface of the carpet, and heat is dissipated from the gap, and the four corners of the carpet are supported by supports. However, it is almost impossible to support the carpet without sagging, and as a result of selective heating of the central part as it approaches the heating means, uneven heating of the plastic sheet occurs, and furthermore, such sagging causes uneven heating of the plastic sheet. There are problems such as thermal deformation such as shrinkage of the carpet when heated. [Means for Solving the Problems] As a means for solving the above-mentioned conventional problems, the present invention provides a net 11 stretched over the top surface of a box-shaped heating furnace 1 in which a heating means 2 is installed. To provide a heating device for a molded carpet 5, characterized in that a pair of rails 3 on which carpet supports 4 are slidably installed are disposed above both side edges of the carpet, and the rails 3 are movable up and down. It is something. [Operation] The operation of the present invention based on the above configuration is as follows. The carpet is supported by a support and placed on the heating furnace, and the rail is moved down to place the carpet on the net of the heating furnace. The plastic sheet of the carpet is then heated and softened by the heating means. At this time, the plastic sheet softens and becomes slightly sticky to the net. Once heating is complete, move the rail upwards and remove the carpet from the net.
Thereafter, the carpet is transferred to the mold side via the support on the rail. [Effects of the invention] Therefore, in the present invention, since the heating furnace is heated by covering the carpet with the carpet, almost no heat escapes, greatly improving thermal efficiency, and the plastic sheet of the carpet is heated during heating. Since it adheres to the net, thermal deformation such as shrinkage of the carpet is suppressed, and since the carpet is supported by the net when heated, the carpet only needs to be supported at least at the rear end by a support, and the four corners are supported. Since there is no need to install supports, fewer supports can be installed, and therefore the rails can be made shorter accordingly.The carpet can be placed on the heating furnace without sagging, so heating is done evenly. The effect mentioned above is produced. [Embodiment] The present invention will be explained with reference to an embodiment shown in FIGS. A net 11 is set up. A pair of rails 3 are arranged above both side edges of the heating furnace 1, and the rails 3 are sloped slightly lower toward the rear. The rail 3
A support 4 is slidably installed on the support 4 via rollers 42, and a pin 41 is extended from the support 4.
The rail 3 is vertically movably supported by piston rods 61 of a pair of hydraulic cylinders 6 at the front end and by a piston rod 71 of one hydraulic cylinder 7 at the center of the rear end. Furthermore, shock absorbers 9 each having a spring 91 are attached to the front ends of the rails 3.
Limit switch 8 and stopper 3 are installed at the rear end.
1 is installed. In the above structure, the four rear corners of the carpet 5 lined with the plastic sheet 51 are connected to the pins of the support 4.

[Table] Repeat steps 4 → 7 below. The present invention is not limited to the above embodiments; for example, a perforated plate may be used as the net, and the vertical movement of the rail may be performed using an air cylinder, a gear, or the like.
