Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device for winding an edge portion of a molded ceiling attached to a vehicle such as an automobile.

(Prior Art) A ceiling material is attached to a ceiling of a vehicle such as an automobile. There are various types of ceiling materials, and one of them is a molded ceiling. This is because a synthetic resin is molded into the size and shape of the ceiling, and is fitted or adhered to the inside of the ceiling. In this case, the outer skin of the edge portion of the molded ceiling is bent inward and pressed from above to give the edge portion a rounded shape and improve the appearance. In the past, this work was carried out manually, but in order to increase the efficiency, a device was automatically invented that automatically wound the skin, and the applicant of the present patent has already filed a patent application. No. 61-146507). This will be described with reference to FIG. 4. Reference numeral 1 is a base plate, and a rack gear 2 with teeth facing upward is integrally attached to a part of the base plate. A guide plate 3 is provided on the side of the rack gear 2 of the base plate 1.
A slide base 4 is supported by the slide base 4 so as to be movable in the left-right direction in the drawing.

A rod 6 of a cylinder 5 is connected to the slide base 4 and is moved by the operation of the cylinder 5. A gear 8 is supported by a shaft 7 on the slide base 4 and meshes with the rack gear 2 described above. The guide plate 3 further rotatably supports a shaft 10 integrally mounted with a gear 9 above the gear 8, and the gear 9 meshes with the gear 8. An arm 11 is integrally attached to the gear 9, and a claw 12 is attached to the tip of the arm 11 by a bolt 13 so as to face upward. Nail 12
Is the molded ceiling that is the work placed on the work receiver 14.
It is designed to face the edge of 15.

The device thus configured operates as follows. In the illustrated state, that is, when the rod 6 of the cylinder 5 is most protruded, the gear 8 is located near the right end on the rack gear 2 as shown by the solid line in the figure. At this time, the pawl 12 sets the position of meshing of the gears 9 and 10 so as to be separated from the molded ceiling 15 as shown in the drawing. In this state, the molded ceiling 15 is placed on the work receiver 14 such that the edge portion thereof projects outward from the work receiver 14, and a reinforcement 17 having a welding point 16 is partially provided on the upper portion thereof. Set.
When the rod 5 is retracted by operating the cylinder 5, the slide base 4 that moves leftward in the figure together with the rod 6
The gear 8 rotatably supported by the shaft 7 moves to the left while rotating counterclockwise by meshing with the rack gear 2. Therefore, the gear 9 rotates clockwise and the arm 11 moves the claw 12 diagonally upward. Then, the edge portion of the molded ceiling 15 is bent inward by pressing. When bent inward, weld horn from above
18 will be processed and welding will be performed.

(Problems to be Solved by the Invention) With the advent of the device described above, the work of rolling up the skin ceiling has become significantly easier and the work speed has become faster, but further research has left some points to be improved. It was clarified that there is. That is, in the above-mentioned device, since the movement of the claw is performed by the meshing of the gears, the movement trajectory of the claw is constant, and if there is some dimensional variation in the product of the molded ceiling, this cannot be dealt with, resulting in poor quality. There is something that happens.

The present invention has been made in view of this point, and the structure thereof is completely different from that of the above-described conventional one to solve the above problems.

(Means for Solving the Problems) As means for solving the above problems, the present invention makes contact with the skin portion of the edge of the molded ceiling and folds it, and presses after the folding to wind the portion inward. In a winding device for a molded ceiling, a first cylinder mechanism that vertically drives a claw that comes into contact with and presses against the skin portion, an upper and lower two-position limit switch attached to the cylinder mechanism, and the first
And a second cylinder mechanism that drives the tilt base in the front-back direction of the molded ceiling.

(Operation) With such a configuration, when the claw is moved by the first cylinder mechanism, the vertical movement range of the claw can be freely set by the upper and lower limit switches, and the claw and the first cylinder mechanism can be set. Is driven diagonally by the second cylinder mechanism, and therefore the amount of lateral movement of the pawl can also be changed by changing the operating stroke of the second cylinder mechanism. Therefore, unlike the above-mentioned technology, there is no possibility that the product will be defective.

(Embodiment) Next, an embodiment of the present invention will be described with reference to FIG.
Reference numeral 19 denotes a unit base, which is fixed to the upper part of the main body base 20. A guide rail 21 is attached to the unit base 19. An inclined base 23 is movably mounted on the guide rail 21 via a bearing case 22 along the guide rail 21. The upper surface of the tilted base 23 is tilted toward the molded ceiling, which will be described later, and the first cylinder mechanism 24 is attached to the upper part thereof. The first cylinder mechanism 24 is a rod 25
Is moved in the vertical direction in the figure, and upper and lower limit switches 26, 27 are attached to the side portions.

The limit switches 26 and 27 are provided with arms 28 and 29 so as to come into contact with a dog 31 attached to the lower end of a guide rod 30 that moves together with the rod 25. The limit switches 26 and 27 are switched to stop the first cylinder mechanism 24 when the arms 28 and 29 contact the dog 31. A guide base 32 supports the guide rod 30 with a bearing 33. A claw 35 is attached to the rod 25 via a claw mounting base 34. The tip of the claw 35 faces the molded ceiling 37 (work) on the work receiver 36. 38 is a work clamp. The unit base 19 is provided with a second cylinder mechanism 39, and a rod 40 protruding and retracting from the second cylinder mechanism 39 is attached with a base end of a connection block 41 having a tip fixed to the inclined base 23. There is.

The device thus configured operates as follows. First, as shown in the drawing, the positional relationship between the claw 35 and the molded ceiling 37 is so positioned that the upper end of the claw 35 faces the lower part of the edge (skin) of the molded ceiling 37. This positioning is performed by operating the first cylinder mechanism 24 and the second cylinder mechanism 39. After positioning, the first cylinder mechanism
After the pawl 35 is lifted together with the rod 25 of 24 to push the molded ceiling 37 from below and the end edge is lifted, the second cylinder mechanism 39 is operated to pull the tilt base 23. As a result, the edge portion of the molded ceiling 37 bends as shown by the broken line in the figure (second
(See FIG. (A)). Next, as shown in FIG. 2 (b), the bent portion is pressed upward by the claws 35 so that the reinforcement 42 is clamped in the bent portion without a gap.

The guide base 32, the guide rod 30, and the bearing fixed to the first cylinder mechanism 24 when the pawl 35 moves up.
The reference numeral 33 serves to receive a moment load and a torsion load due to a reaction force when the edge portion of the molded ceiling 37 is rolled up. The operation timing of the first and second cylinder mechanisms 24, 39 is performed by a sequence circuit (not shown) associated with the operation of the limit switches 26, 27.

The above operation is performed smoothly because the claw 35 is inclined by the inclined base 23. If the nail 35 is not inclined, as shown in FIG.
There will be a gap between them and 42, or they will be displaced and deformed as shown in FIG. 3 (b).

(Effects of the Invention) Since the present invention is configured as described above,
By operating the first and second cylinder mechanisms at a constant timing, even if there is some dimensional variation in the molded ceiling, which is the work, the work can be reliably rolled in without being affected by it.
