Abstract

PURPOSE:To contrive to simplify the processing operation of skin terminal by a method wherein the end edge of a formed ceiling base material is turned up and wound in through the movement of a movable base and further fixed by pressure to the inside of the end edge of the base material by means of a slide punch for automatic bonding. CONSTITUTION:A formed ceiling 1 is seated on a jig stand 21 and all the following process operation is automatically done by actuating an operating button. A skin terminal 2a overhung beyond the end edge 3a of a base material is faced with the air jetted from an air nozzle 19 so as to be abutted against the under side of the side of a slide punch 18 along the end edge 3a of the formed ceiling base material 3 by the movement of a movable base 13 toward a jig stand 21 side by means of a first cylinder 12. Further, the resultant skin terminal 2a is pressed against a surface to be fixed by pressure 14a on a die 14, which faces to the under side of the end edge of the formed ceiling 1, by lowering the slide punch 18 through a link 16 by means of a second cylinder 15 so as to fix to the inside of the end edge 3a of the base material for automatic bonding.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a skin end treatment device suitable for use in automatically winding and crimping the skin end of a molded ceiling for a vehicle inside the edge of a base material. Regarding.

[Conventional technology]

Conventionally, on the inside of the cabin of the ceiling panel of various vehicles, etc.
It is common practice to install a molded ceiling made of a ceiling base material made of corrugated pole material, resin material, etc. and a skin such as cloth or resin sheet covering the surface of the ceiling base material. By the way, in such a molded ceiling 1, the skin 2 overhanging the edge portion
The terminal 2a of FIG. 3 and FIG. 4 (a), (b)
As shown in (c), a skilled worker manually folds the ceiling base material 3 along the edge 3a and rolls it inward, and then presses this part from above and crimps it. It has been conventionally attempted to improve the appearance of the edge portion of the molded ceiling 1. Here, in Figure 4 (
Figure a) shows the outer skin end 2a before it is rolled up, Figure 4B shows its rolled up state, and Figure 2C shows its crimped state.

Further, reference numeral 4 in FIG. 4 is an adhesive applied to the back side during treatment of the outer skin end 2a.

[Problem to be solved by the invention]

However, in the above-mentioned conventional method for treating the skin terminals 2a, the skin terminal processing is performed manually, which not only requires laborious work and poor labor efficiency, but also requires skill to maintain a constant level of quality accuracy. The problem was that it was difficult to do so. In particular, the edge portion of this type of molded ceiling 1 is often curved, as is clear from FIG. The outer skin end 2a is curved in shape, and the work of wrapping and crimping the outer skin end 2a in accordance with this curved shape is complicated and difficult. Conventionally, no jig or automation technology has been established for this type of skin end treatment work, and all treatment methods have been carried out manually.

For this reason, a device for automatically processing the skin ends 2a in this type of molded ceiling 1 is disclosed in Japanese Patent Application Laid-open No. H-135.
It has already been proposed in the past, such as in Publication No. 230, and the winding and crimping work of the skin terminal 2a has been automated, making it easier and the workability improved, but the structure is complicated and it is a big loss, but the work of each part is difficult. The work stroke is large, so it cannot be said that the work time can be shortened, and if there are variations in size or shape in each part of the molded ceiling, it cannot be accommodated, resulting in quality defects. was unavoidable. In particular, this conventional device has a configuration in which the suppressing claw faces the underside of the epidermal terminal and is moved to roll in the claw, which takes time for the moving stroke and also depends on the overhanging shape and amount of the epidermal terminal. 1. The positioning accuracy is poor and the winding operation is not reliable.It is desired that some kind of countermeasure be taken to eliminate the above-mentioned problems in consideration of these points.

The present invention was made in view of these circumstances, and
The skin ends of the molded ceiling can be properly and reliably and automatically wrapped and crimped along the edge of the base material, which greatly simplifies the processing work and reduces work time and the number of workers. A molded ceiling for vehicles that can reduce the amount of molding used, does not require any skill, can be easily operated by anyone to ensure quality accuracy, and also simplifies the overall configuration of the device, resulting in a significant reduction in molding costs. The purpose of this invention is to obtain a device for treating epidermal terminals.

[Means to solve the problem]

In order to meet such demands, a skin end treatment device for a molded ceiling for a vehicle according to the present invention is provided with a first part that is movably supported on a fixed base in the surface direction of a molded ceiling made of a base material and a skin.
a movable base that is reciprocally driven by a driving means; a die that is provided on the movable base so as to face the lower edge of the molded ceiling and forms the surface to be crimped of the end of the skin; A main body frame that supports a pressurizing link that is erected on the top and is swing-driven by a second drive means; The slide punch is stacked on the inner side of the edge and is pressed against the press-bonded surface on the die to make the die press-bond.

[Effect]

According to the present invention, the molded ceiling is placed on the jig table, and the skin end protruding from the edge of the base material faces the side of the slide punch on the molded ceiling side so as to be able to come into contact with it. The movement of the movable base by the first drive means folds and rolls up the molded ceiling base material along the edge, and the second slide punch
By lowering it by the driving means, it is pressed against the surface to be crimped on the die facing the lower side of the edge of the molded ceiling, and is crimped to the inside of the edge of the base material to automatically join. .
