Description

[Detailed Description of the Invention] The present invention relates to a pressure bonding and heating device for exterior moldings of automobiles, etc.

Moldings are glued and fixed to the outer panels of the bodies of automobiles, etc. for the purpose of decoration and protection. These moldings are bonded together by heating and pressurizing, but in the past, molding heating devices and processing devices were constructed separately on the assembly line. Therefore, each device requires its own drive source, which is expensive and also undesirable in terms of space.

In view of the above-mentioned conventional drawbacks, the present invention has been improved by integrating the pressurizing and heating mechanisms to simplify the device and perform rational pressurization and heating processing.

Embodiments of the present invention will be described below with reference to the drawings. 1a is a pair of left and right front struts, and 1b is a pair of left and right rear struts. Guide rollers 2 in three directions are provided at the upper ends of each of the pillars 1a and 1b. Furthermore, between the front struts 1a and the rear struts 1
horizontal bars 7 and 8 are fixed between
and the advancement wire 13 are hung. One end of the return wire 12 is connected to a winding device using a motor 11 with a brake, and the other end is connected to the back side of the pressing member 4. Further, one end of the advancement wire 13 is connected to an auxiliary member 15, and the other end is connected to a weight 14.

Reference numeral 4 denotes a pressing member, at both ends of which a pressing roller 5 is rotatably supported around a vertical axis;
A heater 6 having an infrared lamp 6a attached to a reflecting plate is provided between both pressing rollers 5. A guide bar 3 is connected orthogonally to the pressing member 4, and is supported by the guide rollers 2 of the support columns 1a and 1b so as to be movable forward and backward. The connecting portion between the guide bar 3 and the pressing member 4 may be connected so that the pressing member 4 can swing freely in the vertical direction.

Further, the guide bar 3 supported by the guide roller 2 is moved forward by the gravity of a weight 14 through a return wire 12 hung between pulleys 9 and 10, and is moved forward through a return wire 12 by a winding device driven by a motor 11. It is designed to move backwards.

Next, the operation of the device of the present invention will be explained.
This device is installed along the transfer conveyor of a vehicle assembly line. The original position of the pressing member 4 is the motor 11
Wire 1 wound by a winding device
2, it is in a state of being moved to the rearward end.

As shown in FIG. 2, when a vehicle with a molding 17 fixed to the side surface of the vehicle body 16 with adhesive 18 is conveyed by a transfer conveyor to a processing station using this device, a signal from an unillustrated carry-in detection device is sent. Then, the brake of the motor 11 is released. As a result, the forward wire 12 is pulled down by the gravity of the weight 14, causing the pressing member 4 to move forward and the pressing roller 5 to come into contact with the molding 17 fixed to the side of the vehicle body being moved by the transfer conveyor. Apply pressure. At the same time, the adhesive 18 of the molding 17 is heated and solidified by the heater 6. Therefore, the gravitational force of the weight 14 acts as a pressing force on the molding pressed by the pressing roller 5.

As described above, the device of the present invention uses a rotatable pressure roller and a heater to simultaneously heat and press the molding bonded to the side of the vehicle body moving on a transfer conveyor, thereby simplifying the work process. It is completed in one step, and since the pressing force is due to the gravity of the weight, a uniform pressing force is obtained and strong adhesion is achieved. In addition, since the amount of advance and retreat of the device and the dimensions of the pressing roller 5 are selected appropriately, even if there is a variation in the position of the molding, this can be absorbed and the molding can be reliably pressed and bonded, and the structure is simple and inexpensive. There are advantages that can be provided.
