1 along the left and right side walls. When the cylinder mechanism 35 is fully extended, the set plug 5
The lower surface A of the body portion 511 of 1 is close to the upper surface of the object to be adhered 2, so that the tip portion 81 of the object to be adhered 8 forms an L-shape along the upper inner wall of the engagement hole 21 and its upper surface. It is pressed against the set plug 51 in the bent state. At the same time, the tip portion 81 is cut by the cutter 7 at the left and right lower edge portions of the body portion 511 of the set plug 51. Since the set plug 51 is heated by the heater 6, the lower surface of the body 511 and the tip 81 that abuts the protrusion 513 are heated, and the adhesive attached to the back surface of the set plug 51 is melted. It becomes viscous and is adhered to the object 2 to be adhered. Next, the cylinder mechanism 35 is shortened, the pressurizing body 5 is raised, and the set plug 51 and cutter 7 are separated from the adherend 2, leaving the tip 81 behind.
At the same time as the cylinder mechanism 35 is retracted, the feed cylinder mechanism 91 is expanded and retracted, the ratchet mechanism 92 is rotated to the right by a predetermined angle, and the feed roller 94 is rotated by a predetermined angle via the gear mechanism 93. The next tip end of the set plug 51 is fed out toward the lower part of the projection 513 of the set plug 51. At the same time, the drive screw 14 rotates to transport the set plug 51 across the moving table 3 to a position facing the next engagement hole 21. The adhesive body 8 is successively adhered to the upper end edge of the engagement hole 21 while repeating the above operations one after another. When adjusting the position of the set plug 51 and the cutter 7 or attaching or detaching the set plug 51 and the cutter 7 due to the type of the adherend 2 or maintenance inspection, etc., the cutter 7 and the bolt can be adjusted by operating the bolt 553 to warm the clamping body 55. 524 to warm the clamping wall 523, the set plugs 51 can be adjusted or attached/detached independently. Further, the adhesive body 8 sent downward by the feed roller 94 passes through the lower guide body 951 surrounding the adhesive body 8, and then passes through the set plug 51.
It will proceed in a straight line without making any bends. Further, the adhesive body 8 located in the guide groove 953 is prevented from transmitting heat from the heater 6 by the heat insulating material 954, and the adhesive on the back surface of the adhesive body 8 will not melt in this area. As explained above, in this invention, all the pasting of the pasting object to the pasting object is done mechanically, so the operator is responsible for attaching and detaching the pasting object and wear and tear of the pasting object in the reel. Since it is only necessary to monitor the condition and replenish the material, the amount of manpower needed for the pasting work can be greatly reduced, and the pasting work does not require any skill. Moreover, in the second invention, in addition to the above-mentioned effects, there is also an effect that the adhesive body can be accurately and reliably supplied toward the pressurizing body. Note that the present invention can be practiced even when the adhesive body is attached only to one corner of the object to be adhered.
