Abstract

PURPOSE:To certainly perform rolling-up work, by mounting a first cylinder mechanism for up and down driving a pawl pressing the skin part of the end edge of the molded ceiling of a vehicle in a contact state, and a second cylinder mechanism for driving the inclined base supporting the first cylinder mechanism in an inclined state in the before-and-behind direction of the molded ceiling to operate both cylinder mechanisms in definite timing. CONSTITUTION:The positional relation between a pawl 35 and a molded ceiling 37 is determined so that the upper end of the leading end of the pawl 35 faces to the lower part of the end edge part (skin) of the molded ceiling 37 by operating a first cylinder mechanism 24 and a second cylinder mechanism 39. After the positioning is finished, the pawl 35 is allowed to rise along the rod 25 of the first cylinder mechanism 24 to press the molded ceiling 27 from below and, after the end edge part is raised, the second cylinder mechanism 39 is operated to draw an inclined base 23. By this method, the end edge part of the molded ceiling 37 is bent. Next, the bent part is pressed from above and a reinforcing member 42 is grasped by the bent part without generating a gap. Further, the operational timing of the first and second cylinder mechanisms 24, 39 is performed by the sequence circuit connected with the operation of limit switches 26, 27.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a winding device for winding up the edge of a molded ceiling attached to a vehicle such as an automobile.

(Prior Art) A ceiling material is attached to the ceiling of a vehicle such as an automobile. There are various types of ceiling materials, one of which is molded ceilings. This is done by molding synthetic resin to the size and shape of the ceiling and attaching it to the inside of the ceiling by fitting or connecting R:g. In this case, the outer skin of the edge of the molded ceiling is bent inward and pressed from above to give the edge a rounded appearance and improve its appearance. In the past, this work was done manually, or in order to improve the efficiency of the process, a device was invented that automatically wraps the skin, and a patent application has already been filed by the applicant for this patent (patent application). No. 146507 (Sho 61-146507), this is the fourth
To explain the figure, l 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, and a slide base 4 is supported on the guide plate 3 so as to be movable in the left-right direction in the figure.

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 on the slide base 4 by a shaft 7, and meshes with the rack gear 2 described above. The guide plate 3 further rotatably supports a shaft 1O having a gear 9 integrally attached above the gear 8, and the gear 9 meshes with the gear 8 described above. An arm 11 is integrally attached to the gear 9, and a claw 1 is attached to the tip of the arm 11.
It is attached upward by two bolts 13. The claw 12 is on the workpiece receiver 14! It faces the edge of the molded ceiling 15 on which the work is placed.

This device configured as described above operates as follows. In the illustrated state, that is, when the rod 6 of the cylinder 5 protrudes the most, the gear 8 is located near the right end on the rack gear 2, as shown by the solid line in the figure. And at this time,
The pawl 12 positions the meshing gears 9 and 10 away from the molded ceiling 15 as shown. In this state, a molded ceiling 15 is placed ia on the workpiece receiver 14 so that its end edge protrudes outward from the workpiece receiver 14, and a reinforcement 15 having a welding point 16 in a part is placed on top of the molded ceiling 15.
Set 7. When the cylinder 5 is actuated and the rod 6 is retracted, the gear 8, which is rotatably supported by the support 7 on the slide base 4 which moves to the left along with the rod 6, engages with the rack gear 2 and rotates counterclockwise. Since it moves to the left while moving, the gear 9 rotates clockwise, and the arm 11 pushes the claw 12 obliquely upward to bend the edge of the molded ceiling 15 inward. Once it is bent inward, the welding horn 18 is machined from above and welding is performed.

(Problem to be solved by the invention) With the advent of the device described above, the work of wrapping the skin ceiling has become significantly easier and the work speed has increased, or there are still areas that need further improvement through subsequent research. That was clarified. In other words, in the above-mentioned device, the movement of the claw is carried out by the meshing of gears, so the trajectory of the movement of the claw is constant.
If there is some dimensional variation in the molded ceiling product, it may not be possible to accommodate this and result in quality defects.

The present invention has been made in view of this point, and is designed to solve the above problems by making the structure completely different from the conventional one.

(Means for Solving the Problems) As a means for solving the above-mentioned problems, the present invention, as a means for solving the above-mentioned problems, contacts the outer skin part of the edge of the molded ceiling and bends it, and after the bending, presses and rolls the part inward. In the molded ceiling wrapping device, a first cylinder mechanism that vertically drives a claw that presses in contact with the skin portion, a limit switch with two positions, upper and lower, attached to the cylinder mechanism, and the first
The cylinder mechanism is configured to include an inclined base that tilts and supports the cylinder mechanism, and a second cylinder mechanism that drives the inclined base in the front-rear direction of the molded ceiling.

(Function) With this configuration, when the pawl is moved by the first cylinder mechanism, the vertical movement range of the pawl can be freely set by the upper and lower limit switches, and the distance between the pawl and the first cylinder mechanism can be set freely. Since the cylinder mechanism is driven in the diagonal direction by the second cylinder mechanism, the amount of lateral movement of the pawl can also be changed by changing the operating stroke of the second cylinder mechanism. Therefore, there is no risk of quality defects occurring in the product as in the above-mentioned technology.

(Example) Next, an example of the present invention will be described with reference to FIG.
A unit base 19 is fixed to the upper part of the main body base 20.

A guide rail 21 is attached to this unit base 19. An inclined base 23 is mounted on the guide rail 21 via a bearing case 22 so as to be movable along the guide rail 21. This inclined base 23
The upper surface thereof is inclined toward the molded ceiling side, which will be described later, and a first cylinder mechanism 24 is attached to the upper portion thereof. The first cylinder mechanism 24 moves the rod 25 in the vertical direction in the figure, and has upper and lower limit switches 26 and 27 attached to its sides.

The limit switches 26 and 27 are provided with arms 28 and 29, which contact a dog 31 attached to the lower end of a guide rod 30 that moves together with the rod 25. Limit switch 26.27 is arm 28
．． 29 is switched to stop the first cylinder mechanism 24 when it comes into contact with the dog 31. A guide base 32 supports the guide rod 30 with a bearing 33. A pawl 35 is attached to the rod 25 via a pawl attachment base 34. The tip of the claw 35 faces a molded ceiling 37 (workpiece) on the workpiece receiver 36. 38 is a work holder. A second cylinder mechanism 39 is provided on the unit base 19, and a rod 40 that protrudes and retracts from the second cylinder mechanism 39 is attached to the base end of a connecting block 41 whose tip is fixed to the tilting base 23. ing.

The device thus constructed operates as follows. First, the positional relationship between the claw 35 and the molded ceiling 37 is determined so that the upper part of the tip of the claw 35 faces the lower part of the edge (skin) of the molded ceiling 37, as shown in FIG. This positioning is
After the zero positioning, which is performed by operating the first cylinder mechanism 24 and the second cylinder mechanism 39, is completed, the claw 35 is raised together with the rod 25 of the first cylinder mechanism 24 to push the molded ceiling 37 from below, After lifting the end edge, the second cylinder mechanism 39 is activated to lower the inclined base 23.
pull. As a result, the end edge of the molded ceiling 37 is bent as shown by the broken line in the figure (see FIG. 2(a)), and then the second
As shown in Figure (b), the bent portion is pressed from above with the claws 35 so that the reinforcement oath 42 is held between the bent portions without any gaps.

When the claw 35 rises, the guide base 32, guide rod 30, and bearing 33 fixed to the first cylinder mechanism 24 receive the moment load and torsional load due to the reaction force when the edge of the molded ceiling 37 is rolled up. do.

1st. The actuation timing of the second cylinder mechanism 24.39 is determined by a not-shown sequence circuit associated with the actuation of the limit switches 26.27.

The above operations are performed smoothly because the claws 35 are inclined by the inclined base 23. If the nail 35 is not inclined, a gap may be created between the epidermis and the phosphorus 42 as shown in FIG. 3(a), or the position may be shifted and deformed as shown in FIG. 3(b). I will do it.

(Effect of the invention) Since the present invention is configured as explained 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, it is possible to perform the reliably winding work without being affected by the variation.
