Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a seat assembly device that assembles a seat by fixing it to a seat frame while keeping the trim cover of the seat stretched.

[Prior art]

Generally, the seat is made of a seat pad, such as urethane, that provides sufficient elasticity for the seated person.
and a slab material glued onto the pad to give a sense of volume and feel. Further, the lining is disposed under the pad, the skin (trim cover) is disposed on the slab material, and the pad is disposed on the frame (seat frame).

Such a seat is assembled by pulling the trim cover while compressing the seat and, by extension, the pad, and fixing it to the seat frame while keeping it stretched. In other words, the core wire provided on the edge of the trim cover,
Between the locking piece provided on the bottom of the seat frame,
The trim cover is clipped to the seat frame by installing and staking a C-shaped clip called a hog ring. The hog ring is built into a special tool called the hog ringer, and when you operate the hog ringer trigger,
The caulking of the hog ring that has already been erected and the erection of the next hog ring are performed continuously.

That is, the seat assembly is generally performed as follows.

(1) First, the sheet is half-turned on a support table provided in the main body, and is loaded and supported.

(2) While compressing the pad, pull the edge of the trim cover so that it is adjacent to the locking piece of the seat frame.

(3) With the pad compressed, operate the hog ringer to install the hog ring between the core wire of the edge of the trim cover and the locking piece, crimp the end of the hog ring to deform it, and clip the trim cover to the seat frame. Stop it.

[Problems with conventional technology]

As mentioned above, in the known seat assembly process, the operator must operate the hog ringer while keeping the pad compressed. In other words, the construction and deformation of the hog ring are automatically performed by operating the hog ringer, but other steps are dependent on manual operations by the operator.

In this way, with the known methods that mainly involve manual operation, assembly work cannot be performed efficiently, and
There is no room for reducing man-hours. Additionally, the worker must continue to compress the pad during work, which causes fatigue to the worker. Furthermore, since the hog ringer has a considerable weight, it places a heavy burden on the hands of the operator, which also increases the fatigue of the operator.

Therefore, a device for releasing the operator from the pad compression process is disclosed in Japanese Utility Model Application No. 59-154200. According to this device, a pressing plate is provided on the main body above the support table. This pressing plate is configured to be movable up and down by a cylinder, and the sheet and thus the pad are compressed between the pressing plate and the support table during operation.

According to this device, the seat assembly process is semi-automated, reducing worker fatigue.

However, even though the worker is freed from the pad compression process, he or she must pull the edge of the trim cover with one hand and operate the hog ringer held in the other hand to erect and deform the hog ring. Must be.

[Purpose of invention]

The purpose of this invention is to provide a sheet assembly device that further advances the automation of the assembly process.

[Summary of the idea]

To achieve this purpose, according to this invention,
A locking member for pulling the edge of the trim cover is slidably incorporated into the main body, and a hog ring is also incorporated into the main body so as to be movable up and down. here,
The locking member includes a hook capable of locking the core wire of the edge of the trim cover, and is configured to be slidable. Then, when the core wire is locked to the hook, the locking member is
While pulling the core wire and tensioning the trim cover, slide it to the hog ring position, that is, a position where the hog ring can be installed between the trim cover and the locking piece.

The hog ringer is placed at an upper position where it does not become an obstacle while the locking member is sliding, and is configured to descend and perform a predetermined operation after the locking member slides.

[Effect]

With the above configuration, the operator only needs to lock the core wire of the edge of the trim cover to the hook of the locking member, and the other steps are automated.

〔Example〕

Hereinafter, embodiments of this invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the sheet assembling device 10 according to this invention is capable of stacking sheets 12 in an inverted manner.
It includes a support table 14 to be supported, and a press plate 16 that clamps and compresses the sheet between the support table and the support table. Support table 14, press plate 16
Both are built into the main body 18, and are configured so that relative lifting and lowering movements occur between them. In the embodiment, only the support table is formed to be able to move up and down. That is, the cylinder 22 is attached to the main body 18, and its piston 23 is fixed to the center of the bottom surface of the support table 14. The support table 14 also positions the corners of the sheet 12.
It has a positioning jig 15. On the other hand, pressing plate 1
6 is fixed to the lower end of the support rod 24 at the center of the main body, and the upper end of the support rod is rotatably supported by a cantilever beam (not shown) provided above the main body 18. If necessary, the press plate 16 may also be configured to be movable up and down.

The assembly device 10 further includes a locking member 26 and a hog ringer 28, both of which are incorporated into the main body 18. The locking member 26 includes a support frame 29 which is attached to the support rod 24 via cylinders 30,32. As can be clearly seen from FIG. 2 in addition to FIG. 1, a pair of cylinders 34 are attached to the support frame 29,
A hook 36 is swingably provided at the lower end of each piston 35. The hook 36 is attached to a pin 40 on a bracket 38 fixed to the support frame 29.
A long hole 42 which is pivotally supported by and extends horizontally.
is formed in the hook. Further, a bifurcated fork member 44 is fixed to the lower end of the piston 35,
The hook 36 has a pin 46 extending through the elongated hole 42.
is supported between the forks of the fork material 44. The support frame 29 is formed to have a U-shaped cross section,
An opening 48 is formed from the upper frame plate 49 to the support frame body, and a pair of openings 50 are formed from the upper frame plate 49 to the support frame body.
6 and are formed on the lower frame plate 51, respectively. Note that the opening 49 is provided at a position that avoids contact with the hog ring 28, and the opening 50 is provided at a position that exposes a locking piece on the back of the seat, which will be described later.

In the above configuration, the support frame 29 is slid in the left-right direction in FIG. 1 by the operation of the pistons 30 and 32. Furthermore, when the cylinder 34 operates, the pin 46 is guided by the elongated hole 42 and moves up and down together with the piston 35, so the hook 36
It is swung around the pin 40. As the hook 36 swings counterclockwise and is pressed against the lower frame plate 51 of the support frame, the core wire 13 of the trim cover 11 is moved between the hook and the lower frame plate 51, as will be described later. Then, it gets stuck in there so that it can't be removed.

The Hoglinger 28 is well known, and its basic structure and operation will not be described in detail. However, by operating it, the built-in almost C-shaped hog ring can be moved between multiple objects (in the example, the core wire,
It goes without saying that the locking piece is installed on the corresponding locking piece and then swaged and deformed to clip the object. In the known sheet assembling apparatus, the hog ringer 28 is held and operated by the operator, but in this invention, it is incorporated into the main body 18, and the operator is freed from holding the hog ringer. That is, a support plate 58 is attached to a guide rail 54 and a screw rod 56 which are installed on the main body 18, and this support plate slides along the guide rail when the screw rod rotates. The cylinder 60 is fixed to the support plate 58, and the hog ringer 28 is attached to the tip of the piston 61.

As shown in FIG. 3, the sheet 12
The seat frame 64 is provided with a locking piece 66 made of a bent piece obtained by pressing the seat frame 64, for example. In this embodiment, since it is a vehicle seat, a portion of the seat 12 is missing at the wheel side, and two locking pieces 66 are formed on each of three sides.

Since the locking pieces 66 of the seat 12 are provided on three sides, the three sets of locking members 26 are arranged on the main body 18, separated by 90 degrees. On the other hand, only one hog ringer 28 is provided. Of course, the arrangement of the locking member 26 and the hog ringer 28 is not limited to this, and may be provided for each hog ringer and each locking member, for example.

With the sheet assembly device 10 having the above configuration,
The sheet 12 is assembled as follows.

(1) The support table 14 is waiting at the lower position, and the hog ringer 28 is waiting at the upper position.
Furthermore, the locking member 26 extends the piston 33 of the cylinder 32 and allows the piston 33 of the cylinder 34 to extend.
5 is waiting in the raised position (see Figure 4). Under such initial position, frame 64
Flip the sheet 12 so that it is facing upward.
However, along the positioning jig 15, the table 14
loaded on top. Then the start button is pressed and according to the predetermined program,
A predetermined process is performed under the operator's switch operation.
This is done sequentially as follows.

(2) First, the cylinder 22 operates, and the piston 23
rises. The support table 14 supports the piston 2
3, the sheet 12 is clamped and compressed between the press plate 16 and the press plate 16. At this point,
Each component is in the position shown in FIG.

(3) Hold the trim cover 11 of the hanging sheet 12, fold it back upwards, and stack the core wire 13 at the end of the trim cover on the lower frame plate 51 as shown by the dashed line. Of course, the core wire 13 is connected to the lower frame board 5.
1 and placed in a position where it can be locked onto the hook 36. Only this step is performed manually by the operator.

(4) For example, by stepping on a foot switch, the cylinder 34 is actuated and the piston 35 is lowered. As the piston 35 descends, the hook 36 is pushed by the pin 46 and swings counterclockwise around the pin 40. And core wire 1
3 is locked to the hook 36 and is set in a state where it is sandwiched between the hook and the descending plate 51.

In the embodiment, the hook 36 is formed into a substantially L-shape, and the core wire 13 is configured to be sandwiched between the hook 36 and the lower frame plate 51.
However, the present invention is not limited to this configuration, and for example, the hook 36 may be formed in a ``chest'' shape, and the core wire 13 may be directly latched to the hook before swinging so as not to fall off.

(5) Rotate the support table 14 etc. by 90 degrees,
With the other locking member 26 facing the operator,
Repeat steps (3) and (4).

(6) When the setting of the core wire 13 is completed, the start button is pressed again, the cylinder 32 is activated, and the piston 33 is moved back. The locking member 26 moves to the right as the piston 33 moves to the hog ring position shown in FIG. By this movement of the locking member 36, the trim cover 11 is pulled and fully tensioned. In the hog ring position, the core wire 13 is located substantially above the locking piece 66 of the seat frame exposed through the opening 50 of the lower frame plate.

(7) When the locking member 36 moves to the hog ring position, the motor is started, rotates the threaded rod 56, and the hog ringer 28 moves perpendicular to the drawing to a predetermined position.

(8) When the hog ringer 28 reaches a predetermined position, the cylinder 60 is actuated, and the piston 61 is moved forward, that is, lowered in the drawing, and reaches the clip position shown by the dashed line. Then, the hog ring 68 is connected to the core wire 13 and the locking piece 6 by the hog ring 28.
6, and is caulked, and the core wire is clipped to the locking piece.

(9) When the clipping is completed, the cylinder 60 is activated and the piston 61 is slightly raised. Also, the motor is driven again to rotate the screw rod and move the hog ring 68 to the next clip position. And by Hoglinger28,
Clipping is repeated on the same side of sheet 12.

(10) When all the clips on one side are completed, the cylinder 60 is actuated to raise the piston 61 to the initial position, and the motor is reversed to return the hog ringer 28 to the initial position.

(11) Then, rotate the support table 14 etc. by 90 degrees so that the other locking member 26 faces the operator, and repeat the steps (6) to (10) above for the other surfaces. Clip-fastening is done on the side.

(12) After that, actuate the cylinder 34 to raise the piston 35. Then, the hook 36 swings clockwise around the pin 40 and the core wire 13
Release the pinch. Furthermore, the cylinder 30 is actuated to advance the piston 31 and the core wire 1 is moved forward.
The locking member 36 is missed by the amount of overlap with 3. In addition, when all the clips are finished,
The piston 61 and the hog ringer 28 have already returned to their initial positions.

(13) Finally, the cylinder 22 operates and the piston 2
3 to return the support table 14 to its initial position. In this state, the core wire 13 is clipped to the locking piece 66 of the seat frame,
A sheet 12 with a trim cover 11 stretched thereon is inverted and stacked on a support table 14 as a finished product.

The above-mentioned embodiments are for illustrating this invention, and are not intended to limit this invention in any way, and any modifications, modifications, etc. made within the technical scope of this invention are also included in this invention. Needless to say.

[Effect of idea]

As described above, according to this invention, the hog ringer is incorporated into the main body together with the locking member that sandwiches the core wire and moves to the hog ring position.

With such a configuration, the operator only has to lock the core wire in the locking member, and all other steps are automated. Therefore, the number of man-hours can be significantly reduced and the assembly process can be carried out efficiently. Further, the operator is freed from holding the hog ringer, and the sheet can be assembled easily and quickly without causing fatigue or other burdens to the operator.
