BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin edge fixing device for fixing the edge of a skin adhered to the surface of a base material.

0002

[Prior Art] Conventionally, this type of skin edge fixing device has
For example, JP-A No. 63-288734 and Utility Model Application No. 63-1
As disclosed in No. 61726, the edge of the skin is fixed to the edge of the base material in the following manner.

That is, the edge of the skin bent at the edge of the base material is pressed against the fixed surface of the edge of the base material (such as the back surface of the edge of the base material), and then the edge of the skin is pressed with an organic solvent-based adhesive. During this pressing, the edge of the skin is adhered to the fixed surface of the edge of the base material.

0004

[Problems to be Solved by the Invention] However, in the conventional skin edge fixing device described above, an organic solvent-based adhesive is not applied to the surface to be fixed such as the back surface of the base material edge or the back surface of the skin edge.
Since it is necessary to apply the coating in advance with a brush, spray gun, etc., the working environment deteriorates, which is undesirable.

[0005] There are also the following problems. That is, since an adhesive application process is required separately from the process of pressing the outer skin edge to the fixed surface of the base material edge, the number of processes increases and production efficiency decreases. Furthermore, since it is necessary to wait until the end edge of the skin is completely fixed with the adhesive, the production efficiency is still low.

Furthermore, since the adhesive must be applied along the surface to be fixed at the edge of the base material, the structure of the device for driving the brush, spray gun, etc. along the surface to be fixed becomes complicated. . For example, if there are undulations on the back surface of the edge of the base material, it is necessary to move the brush or the like up and down along the undulations.

The present invention has been made to solve the above-mentioned problems, and aims to promote improvement of the working environment and production efficiency, and to simplify the configuration.

[0008]

[Means for Solving the Problems] The means adopted by the present invention to achieve the above object is to fix the edge of the skin adhered to the surface of the base material to the edge of the base material. The part fixing device includes a pressing means for pressing the skin edge bent at the base material edge onto a fixed surface of the base material edge through a pressing member, and the pressing means The pressing member is provided with a fixing means that is provided opposite to the surface to be fixed, and fixes the end edge of the skin layered on the surface to be fixed to the base material from the skin side by the pressing means. shall be.

[0009] Here, as the fixing means, in addition to a device that drives out fasteners such as rivets or needles with a length that does not penetrate the base material, there is also a device that locally heats the skin overlapping the surface to be fixed of the base material from the skin side. A device that welds the epidermis to the base material by applying ultrasonic vibration or applying ultrasonic vibration is suitable.

0010

[Operation] The skin edge fixing device having the above configuration uses a pressing means to press the skin edge bent at the base material edge onto the fixing surface of the base material edge through the pressing member. Then, the edge of the skin is overlapped with the fixed surface of the edge of the base material. When the edge of the skin is superimposed on the surface to be fixed in this way, the edge of the skin that overlaps the surface to be fixed at the edge of the base material is attached from the skin side to the base material by the fixing means facing the surface to be fixed. Fix it.

[0011] As a result, the fixation of the edge of the skin to the surface to be fixed of the edge of the base material is completed without using an adhesive.

In addition, when the air cylinder 27 is in the original position as shown in the figure, the processing horn 29a at the tip of the ultrasonic welding tool 29 is slightly separated from the skin pressing surface 25, and the through hole that passes through the skin pressing part 23 is inserted. Located within 33. Therefore, when the two-position switching valve 35 connected to the air cylinder 27 is actuated and the air cylinder 27 is driven, the ultrasonic welding tool 29 moves as indicated by the arrow A in the figure.

The right pressing member 37 has an air cylinder 43 and an ultrasonic welding tool 45 having a built-in ultrasonic vibrator connected to each other by a connecting plate 47 on the mounting surface opposite to the skin pressing surface 41. In addition, in the ultrasonic welding tool 45, similarly to the skin pressing part 23 of the left pressing member 17 described above, the processing horn 45a is located in the through hole 49 of the right pressing member 37 with a slight distance from the skin pressing surface 41. From this state, it moves in the direction of arrow B in the figure. Movement of the ultrasonic welding tool 45 along the direction of arrow B is performed by switching compressed air using a two-position switching valve 51 connected to the air cylinder 43. Also, a right pressing member 37 waiting on the right side of the base 3
The clearance between the skin pressing surface 41 and the right fixed surface KHR is set to be less than or equal to the thickness of the right edge HTR of the skin.

The ultrasonic welding tools 29 and 45 have ultrasonic oscillators 53 and 55 that generate ultrasonic signals whose amplitude is controlled by a direct current supplied from a voltage control device (not shown).
are connected to each. Then, this ultrasonic oscillator 53 is
, 55, the ultrasonic vibrator is vibrated by the amplified ultrasonic signal, and this vibration is transmitted to the welded object (skin) through the processing horns 29a, 45a. (right and left edges of H) to weld the object to be welded.

Next, the electronic control device 9 which controls the above-mentioned skin edge fixing device 1 will be explained. The electronic control unit 9 is configured as a logic operation circuit mainly including a CPU 9a, ROM 9b, and RAM 9c, and is connected to a common bus 9d.
Input/output with the outside is performed through input/output ports 9e that are mutually connected via the input/output ports 9e. And, in the input/output port 9e,
Each solenoid of the two-position switching valves 35 and 51 described above, the horizontal drive device 19 and the vertical drive device 21 on the left winding fixing section 5 side, the horizontal drive device 39 on the right winding fixing section 7 side, and the workpiece. In addition to the clamp driving device 15, ultrasonic oscillators 53, 55, and the like, an operation panel 57 and the like for instructing the apparatus to start fixing the epidermal edge portion is connected.

Next, the skin edge fixing control (routine) carried out by the skin edge fixing device 1 having such a configuration will be explained using the flowchart shown in FIG. Figure 2
The epidermal edge fixing routine is repeatedly executed from the time the power is turned on until the power is turned off, through initial processing immediately after the power is turned on.First, it is determined whether or not to start fixing the epidermal edge. A judgment is made based on whether or not the start switch on the operation panel 57 is pressed (step 100, hereinafter the step will simply be referred to as S), and the process waits until the start switch on the operation panel 57 is pressed.

[0023] Here, when it is determined to start fixing the edge of the skin based on the pressing operation of the start switch, the skin H and the base material K are
The workpiece W with the bonded parts is clamped to the concave holding surface 11 of the base 3 (S110). That is, the electronic control device 9 outputs a drive signal (clamp signal) to the work clamp drive device 15 to drive the work clamp 13, which had been retracted to the upper side of the base 3, to the clamp position shown in FIG. W is pressed against the concave holding surface 11 and clamped. After that, drive signals are output from the electronic control device 9 to the horizontal drive device 19 on the left side winding fixing section 5 side, the vertical direction drive device 21, and the horizontal direction drive device 39 on the right side winding fixing section 7 side, and the following steps are performed. The left and right pressing members 17, 37 are moved (S120).

Regarding the movement of the left and right pressing members 17, 37, while referring to FIGS. 3 and 4, the left pressing member 1
7 and the right pressing member 37 will be explained separately.

First, the movement of the right pressing member 37 will be explained. From the electronic control device 9 to the right winding fixing part 7
When a drive signal is output to the horizontal direction drive device 39 on the side,
As shown in FIG. 3, the right pressing member 37 moves horizontally in the direction of arrow E from a standby position C indicated by a chain double-dashed line in the figure to a pressing position D indicated by a solid line in the figure.

As described above, the skin pressing surface 41 of the right pressing member 37 and the right fixed surface KHR on the right edge KTR side of the base material
The clearance between them is set to be less than or equal to the thickness of the right edge HTR of the skin. Therefore, by moving the right pressing member 37 from the standby position C to the pressing position D, the right edge of the skin HTR is moved from the right edge of the base material KTR as shown in FIG.
is bent and pressed against the right fixed surface KHR.

Next, the movement of the left pressing member 17 will be explained. When moving this left pressing member 17,
First, a drive signal is outputted from the electronic control device 9 only to the horizontal direction drive device 19 on the side of the left winding fixing part 5, and as shown in FIG. It moves horizontally in the direction of arrow I from to an intermediate position G shown by a solid line in the figure.

When the left pressing member 17 moves to this intermediate position G, the electronic control unit 9 outputs a drive signal to the horizontal drive device 19 and the vertical drive device 21 at the same time. Specifically, a drive signal for moving the left pressing member 17 in the horizontal direction (in the direction of arrow I in FIG. 3) is continuously output to the horizontal drive device 19, and the vertical drive device 21
A drive signal for lowering the left pressing member 17 is output. As a result, as shown in FIG. 4, the left pressing member 17 moves obliquely downward in the direction of arrow M from an intermediate position G shown by a chain double-dashed line in the drawing to a pressing position J shown by a solid line in the drawing.

Note that the left pressing member 17 along the direction of arrow M
When moving, the clearance between the skin pressing surface 25 and the left fixed surface KHL of the base material K is the left edge of the skin HTL.
Care has been taken to maintain the thickness below. for example,
If the horizontal drive device 19 and the vertical drive device 21 use an air cylinder as a drive source, it is sufficient to supply the compressed air with a difference in pressure or amount of supply air.
If a servo motor is used as the drive source, the pulses may be applied with a difference in the number of pulses.

Therefore, by moving the left pressing member 17 from the standby position F to the intermediate position G, the left edge H of the outer skin
TL is bent at the left edge portion KTL of the base material, as shown in FIG. Thereafter, by moving from this intermediate position G to the pressing position J, the left edge HTL of the epidermis is
As shown in , it is pressed against the left fixed surface KHL.

Note that the intermediate position G is defined by arranging a position detection sensor such as a microswitch at a position corresponding to the shape of the base material, etc., and a detection signal from this sensor is input to the electronic control device 9. Then, the electronic control device 9 determines whether the left pressing member 17 has reached the intermediate position G. When the left pressing member 17 reaches the intermediate position G, the electronic control device 9 simultaneously outputs a drive signal to the horizontal drive device 19 and the vertical drive device 21, as described above.

By performing S120 in this way,
The left and right edge portions of the skin H are pressed and brought into close contact with the fixed surface of the base material K (see FIG. 4).

Thereafter, the electronic control unit 9 outputs a drive signal to each solenoid of the two-position switching valves 35, 51 to drive the air cylinders 27, 43, and the ultrasonic welding tools 29, 4
5 is advanced toward the left and right fixed surfaces KHL and KHR of the base material K that face each other (S130). In this way, the processing horns 29a and 45a at the tips of each ultrasonic welding tool are pressed against the surfaces of the left and right edge portions HTL and HTR of the skin H that is in close contact with the surface to be fixed.

Then, the electronic control device 9 outputs a drive signal to the ultrasonic oscillators 53, 55, transmits the ultrasonic signal to the ultrasonic welding tools 29, 45, and fixes the left and right edges HT of the skin H.
L, processing horn 29a pressed against the HTR surface;
45a, weld the left and right end edges HTL and HTR of the skin H to the left and right fixed surfaces KHL and KHR of the base material K (S
140).

[0035] Once the welding of the edge of the skin is completed in this way,
The electronic control device 9 outputs a drive signal to each solenoid of the two-position switching valves 35, 51 to drive the air cylinders 27, 43, and the ultrasonic welding tools 29, 45 are attached to the left and right fixed surfaces KH.
L, retreat away from KHR (S150). After that, the electronic control device 9 sends drive signals (
A return signal) is output to return the left and right pressing members 17, 37 from their respective pressing positions D, J shown in FIG. 5 to standby positions C, F shown in FIG. 3 (S160).

Furthermore, the electronic control device 9 outputs a drive signal (unclamp signal) to the work clamp drive device 15 to raise the work clamp 13 from the clamp position shown in FIG. The pressing of W is released (S170). After that, the process moves to S100 and this routine is repeated.

As explained above, the skin edge fixing device 1 of this embodiment has the following functions by moving the left and right pressing members 17 and 37 to the respective pressing positions D and J shown in FIG.
The left and right edges HTL and HTR of the epidermis H are respectively connected to the base material K.
It is bent at the left and right end edges KTL and KTR of the base material K, and is pressed against the left and right fixed surfaces KHL and KHR of the base material K to make them come into close contact with each other. Then, the ultrasonic welding tools 29, 45 are advanced toward the left and right fixed surfaces KHL, KHR of the base material K, and the processing horns 29a, 45a are moved to the left and right end edges HTL of the skin H that are in close contact with the fixed surfaces. , the right and left edges HT of the skin H through the processing horns 29a, 45a.
L and HTR are welded to the left and right fixed surfaces KHL and KHR of the base material K.

As a result, according to the skin edge fixing device 1 of this embodiment, the left and right edges HTL, HTL, and the left and right edges HTL of the skin H are fixed to the left and right surfaces KHL, KHR of the base material K, KTL and KTR, respectively.
Since the HTR can be fixed without using an adhesive, it is possible to improve the working environment by avoiding deterioration in the working environment caused by the use of organic solvent-based adhesives. Furthermore, since the adhesive application process and the waiting time until the adhesive fixing is completed are unnecessary, production efficiency is improved.

Furthermore, a device for driving a brush, spray gun, etc. to apply the adhesive along the fixed surface of the edge of the base material is not required, and the structure can be simplified.

In addition, in this embodiment, the left and right edges HTL of the skin H in the left and right edges KTL and KTR of the base material K,
Bending of HTR and left and right fixed surfaces KHL, KH of base material K
The structure is such that the close contact (overlapping) of the left and right edge portions HTL and HTR of the epidermis H to R is carried out in parallel by movement of the left and right pressing members 17 and 37. Therefore, two operations can be performed with only a single member to be driven (pressing member), the number of members to be driven is reduced, and the configuration is simpler.

Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment in any way, and can be implemented in various ways without departing from the gist of the present invention. Of course. For example, instead of the ultrasonic welding tools 29 and 45 equipped with processing horns for welding by ultrasonic vibration, a heat welding machine having a heating terminal at the tip for heating the welded parts may be used.

Furthermore, as shown in FIG. 6, a fastener such as a stud 100 or a needle 102 having a length that does not penetrate the base material K is driven out from the outside of the left and right edges HTL and HTR of the skin H using compressed air. The punching equipment, ultrasonic welding tool 29
, 45 can also be used. In this case,
Since it is not necessary to bring the fastener punching device into contact with the skin H (edge portion), the air cylinders 27, 43 and the two-position switching valves 35, 51 are not necessary.

[0043]

Effects of the Invention As detailed above, according to the skin edge fixing device of the present invention, the skin edge bent at the base material edge can be pressed against the fixed surface of the base material edge. The edge of the skin overlapping the surface to be fixed can be fixed to the base material without using an organic solvent-based adhesive. As a result, it is possible to avoid deterioration of the working environment due to the use of adhesives and improve the working environment. In addition, production efficiency is improved because the adhesive application step and the waiting period until the end edge of the skin is fixed are no longer necessary.

Furthermore, there is no need for a device for driving a brush, spray gun, etc. to apply the adhesive along the fixed surface of the edge of the base material, and the structure can be simplified.
