Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a winding device for the end of a seat skin cover.

(Prior Art) As shown in FIGS. 5 and 6, the seat cushion S1 and the seat back S of the conventional seating seat S are
A suspension wire W is attached to each end C1 of the seat skin cover C of No. 2, and this end C1 is connected to the seat cushion frame F1 and the seat back frame together with the ends P1a and P2a of the seat cushion pad P1 and the seat back pad P2. They are wrapped around the straight portions of F2 and connected to hanging trim members T1 and T2 by hog rings R, thereby covering the seat cushion pad P1 and the seat back pad P2. In this way, the seat cushion pan U1 and the seat bag pan U2 are fitted on the back side of the seat cushion S1 and the seat bag S2 covered with the skin cover C, so that the end portions P1a and P2a are isolated from the outside.

To connect the seat skin cover C to the hanging trim members T1 and T2, the edges of the skin cover C are pulled by hand to smooth out the wrinkles, and as shown in FIG. This is done by connecting T1 and T2 with a hog ring R.

(Problems to be solved by the invention) In the above-mentioned conventional winding structure of the end of the seat skin cover, the end of the seat skin cover C is manually pulled to adjust the tension and remove wrinkles. Since this is only carried out locally, there are variations depending on the location and degree of the terminal being pulled, making it impossible to completely remove wrinkles. Further, such pulling requires a large force of about 5 to 10 kg/f, which places a burden on the operator. In addition, as a structural problem, hanging trim material T
1 and T2 need to be arranged around the seat cushion pad P1 and the seat back pad P2, which has the disadvantage of increasing manufacturing costs.Also, there is a problem in the work that the distance between the hanging trim members T1 and T2 is high. When fixing the hog ring R, a fixing error is likely to occur due to a failure in fastening, resulting in poor workability, and such a failure in fastening could cause the hog ring R to bounce, thereby injuring the operator. Furthermore, the fastening work using the hog ring R has the disadvantage that the operator must visually confirm the work, and in such work it is very difficult to maintain the retracted position of the end C1 of the seat skin cover C at a constant position. This has the disadvantage that the sheet quality is unstable because it often causes variations in the quality of the sheet.

(Means for Solving the Problems) In order to solve the above-mentioned problems of the prior art, the seat skin cover terminal winding device of the present invention includes a skin cover constituting a seat member of a sitting seat, a compressible seat pad, and a base member on which the seat pan is placed with the skin cover and the seat pan positioned below and above the seat pad, respectively; a seat pad compression mechanism that presses the seat pad together with the seat pan toward the base member; , a roller mechanism including a roller for pressing the skin cover toward a corresponding side of the seat pad when the seat pad is compressed by the seat pad compression mechanism; comprising a fluid pressure cylinder that can gradually move the pressing position of the skin cover to the seat pad from the bottom to the top of the seat pad, and a drive device that rotates the roller in a direction to pull the skin cover upward; When the compression by the seat pad compression mechanism is released after the skin cover is crimped by the roller mechanism, the upper edge of the side of the skin cover is locked to the periphery of the seat pan as the seat pad is restored. It is said that (Function) In the seat cover terminal winding device of the present invention, after the seat pad is compressed and pressed by the seat pad compression mechanism, the skin cover is crimped toward the corresponding side of the seat pad by the roller mechanism, and then the seat pad compression mechanism The end of the skin cover can be rolled up and held by a simple operation of releasing the compression of the seat pad and using the restoring force of the seat pad to lock the upper edge of the side of the skin cover to the periphery of the seat pad. can. Here, the rollers of the roller mechanism are gradually moved from the bottom to the top of the seat pad by the fluid pressure cylinder, and at the same time are rotated by the drive device in the direction of pulling the skin cover upward, so that the seat pad of the skin cover is It is possible to effectively remove wrinkles from the skin cover at the same time as crimping the corresponding sides.

(Embodiment) Next, an embodiment of the seat skin cover end winding device of this invention will be described with reference to FIGS. 1 to 4. Although this figure shows only the attachment of the outer skin cover C to the seat cushion S1, a similar device can be used for the seat bag S2 as well.

In FIG. 1, 1 is a molding table for adhesively molding the skin cover C and the cushion pad P1, and the seat cushion S1 of the seating seat S is installed on the molding table 1 with the skin cover C facing down. (FIG. 1 shows the state after adhesive molding). Here, the seat cushion pan U1a located on the seat cushion pad P1 has an upward hook-shaped flange portion 3 at its peripheral edge.

Reference numeral 4 denotes a seat cushion pad compression mechanism for compressing the seat cushion pad P1 from above, which is vertically attached to the horizontal frame portion 5a at the top of the machine frame 5 surrounding the seat cushion S1. It has an air cylinder 6 and a work gripping tool 7 fixed to the lower end of the piston rod 6a.
Downward pins 8 to 8 are protruded from the work gripping tool 7, and these pins 8 to 8 are connected to the seat cushion pan U1.
The seat cushion pan U1a is fitted into the frame grip holes 9 to 9 formed in the control panel 1.
It is possible to move up and down under the control of 0 as the piston rod 6a of the air cylinder 6 expands and contracts.
Note that, as the frame gripping holes 9 to 9, holes provided as appropriate to reduce the weight of the seat cushion pan U1a can be used.

Further, trim members 11 made of a material such as polypropylene are fused at appropriate intervals to the edge of the skin cover C, and the trim members 11 engage with the hook-shaped flange portion 3 of the seat cushion pan U1a. It is shaped like a downward hook.

12 to 12 are roller mechanisms provided surrounding the seat cushion S1 and facing each other in two orthogonal directions, as shown in FIG.
A rubber roller 13 arranged approximately parallel to the surface of
, a motor 14 for rotating the rubber roller 13 upward with respect to the surface of the seat cushion pad P1 facing it, and a motor 14 for moving the rubber roller 13 forward and backward diagonally upward with respect to the surface of the seat cushion pad P1. It has an air cylinder 15,
For this reason, the air cylinder 15 is obliquely attached to a mounting frame (not shown) provided on the machine frame 5. Further, in order to ensure parallel movement of the rubber roller 13, the support frame 16 of the rubber roller 13 is guided by guide rods 17, 17 on both sides thereof, and these guide rods 17, 17 are similarly fixed to the mounting frame.

Next, the operation of the above embodiment will be explained.

First, the skin cover C is placed on the pedestal 2 of the molding table 1, adhesive is applied to the contact surface of the sheet cushion pad P1, and the sheet cushion pad compression mechanism is controlled by the control panel 10. The air cylinder 6 of No. 4 is driven to extend the piston rod 6a. Then, the seat cushion pan U1a gripped by the workpiece gripper 7 with the pins 8 to 8 and frame grip holes 9 to 9 inserted into the seat cushion pad P
1, and the seat cushion pad P1
is compressed in the vertical direction toward the skin cover C through the seat cushion pan U1a, and the skin cover C
The sheet cushion pad P1 is adhered to the
When the piston rod 6a is compressed by approximately 1/3, the piston rod 6a reaches its stroke end.

When the next roller mechanisms 12 to 12 are driven and each rubber roller 13 is rotated and moved diagonally upward from the lower end of the seat cushion pad P1 via the air cylinder 15, the rubber roller 13 is moved to the corresponding position on the skin cover C. Seat cushion pad on the sides
1 and gradually moves upward while pulling the skin cover C upward as a result of its rotation. When the air cylinder 15 reaches the stroke end, the rubber roller 1
3 reaches the uppermost position of the seat cushion pad P1, and the trim material 11 of the skin cover C is placed over the hook-shaped flange portion 3 of the seat cushion pan U1a. (See Figure 3).

In this state, when the piston rod 6a of the air cylinder 6 of the seat cushion pad compression mechanism 4 is moved backward and the work gripping tool 7 is raised, the seat cushion pan U1a is raised by the restoring force of the seat cushion pad P1. The trim member 11 of the skin cover C is automatically engaged with the hook-shaped flange portion 3 as shown in FIG. As a result, the skin cover C is placed under tension on the seat cushion pad P1, and then the sewing operation is performed.

After the sewing work is completed, the rubber rollers 13 of the roller mechanisms 12 to 12 are moved back and the sheet cushion S1 is taken out. Then, a new skin cover C for the sheet cushion S1 is placed on the forming table 1 and the same work is carried out. It is done.

In the above embodiment, the skin cover C is formed by using the sheet cushion pad compression mechanism and the molding table 1 required for adhesive molding when the skin cover C is bonded to the seat cushion pad P1. A separate compression mechanism or stand member may be provided as a winding device for the cover end so that the winding operation is performed separately from the adhesive molding.

(Effect of the invention) The winding device for the end of the seat skin cover of the present invention compresses the seat pad using the seat pad compression mechanism, then presses the skin cover against the corresponding side of the seat pad using the roller mechanism, and compresses the seat pad using the seat pad compression mechanism. By locking the upper edge of the side of the skin cover to the periphery of the seat pan with a simple operation of releasing the compression, the skin cover can be rolled up without any manual effort, reducing labor. It is possible to improve work efficiency and stabilize product quality. In addition, since the locked state of the skin cover is reliably maintained with the tension of the skin cover due to the restoring force of the seat pad, fixing errors can be eliminated. Further, the skin cover is pressed against the seat pad by pressing a roller using a fluid pressure cylinder, and the roller is rotated by a driving device, thereby reliably eliminating wrinkles in the skin cover. In addition, the rotation of such rollers applies a certain tension to the skin cover, so by providing such roller mechanisms on each opposing side of the seat pad, it is possible to eliminate variations in the tension applied to the skin cover. Product quality can be improved.
