Description

  The present invention relates to an airbag processing apparatus and a processing method.

Conventionally, when a vehicle equipped with an air bag device is scrapped and dismantled, the inactive air bag device is forcibly activated (deployed air bag) while being dismounted and disposed of. It has been broken.
Such air bag processing methods include an air release type in which an air bag device is forcibly operated at a factory or outdoors, and a processing vehicle is stored in a container provided with a soundproofing and exhausting device. There is a container type in which an airbag device is forcibly operated in a container for processing. Further, as shown in FIG. 4, a front seat airbag device for a driver seat and a passenger seat is provided by a housing 2 (indicated by a two-dot chain line in the drawing) having a soundproof material and an exhaust device 1. A method has also been proposed in which 3,3 and 3 are sealed together with the instrument panel 4 and then forcibly actuated for processing (see, for example, Patent Document 1).

  However, the conventional airbag processing method described above has the following problems. First, in the air bag processing method using the open air method, a large explosion sound is heard when the air bag device is activated, or a large amount of deployment gas diffuses with odor. Moreover, with the spread of airbag devices in recent years, there is a tendency for the ratio of scrapped vehicles of vehicles equipped with airbag devices to increase. For this reason, in order to perform the disposal processing of the airbag device, there is a problem that sufficient soundproofing and smokeproofing measures must be taken for the worker and the surrounding environment.

Next, in the container-type airbag processing method, although soundproofing and smokeproofing measures are taken, it is necessary to put in and out of the container with a forklift or the like for each processing vehicle. Therefore, depending on the configuration of the line for dismantling the scrapped vehicle, there is a problem that the disposal of the airbag device cannot be performed unless the vehicle is once taken off from the line.
Furthermore, since the container of the magnitude | size which can store a processing vehicle is needed, installation expense will be incurred. Moreover, there is a problem that a place for installing such a container must be secured on the line side.

Next, in the airbag processing method of covering the airbag devices 3 and 3 with the casing 2, as shown in FIG. 4, in order to exhibit the soundproofing and smokeproofing performance of the casing 2, It is necessary to cover the ment panel 4 without a gap. Therefore, there is a problem that it takes time to set the housing 2.
In addition to the front seat airbag devices 3 and 3, other airbag devices mounted on the processing vehicle, such as side airbag devices, curtain airbag devices, rear seat airbag devices, front hood airbag devices, In order to perform processing including front bumper airbag devices and other seat belt pretensioner devices that cause similar problems, it is necessary not only to prepare a large number of housings according to them, but also to set the housing time. There is also a problem of inviting an increase in the number of people.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a schematic view for explaining a processing apparatus and a processing method of the side airbag, and FIG. 2 is a cross-sectional view of a sheet member constituting a base body in the example.

  First, the airbag processing apparatus 10 will be described. As shown in FIGS. 1 and 2, the airbag processing apparatus 10 includes an elevating base 12 that covers a vehicle 11 (hereinafter referred to as a processing vehicle) 11 having an airbag apparatus and forms a substantially sealed space S. And a recovery means 13 for recovering the gas in the substantially sealed space S formed by the base body 12.

  The base body 12 has a plurality of skeleton members 14 arranged radially in plan view so as to have a developed shape covering the entire processing vehicle 11, and a sheet member 15 stretched between the skeleton members 14. . A lightweight material (for example, aluminum light alloy) having a required strength is used for the skeleton member 14, and the rigidity of the base 12 is ensured and the weight is reduced.

Further, as shown in FIG. 2, the outermost layer of the sheet member 15 is a rubber-like sheet material 16 having a sound insulation function, the intermediate layer is an insulator material 17 having a sound absorbing function, and the innermost layer is flameproof, A material (for example, a glass fiber material) 18 having a fire resistance and a heat resistance function is provided. As a result, the sheet member 15 is ensured in strength, soundproofing, and smokeproofing performance capable of repeatedly withstanding the explosion sound (impact) generated during the operation of the airbag device, while being reduced in weight.
Note that the sheet member 15 is not limited to the three-layer structure described above as long as a material excellent in flameproofing, fireproofing, heat resistance, sound absorption, and sound insulation is used. A two-layer structure can also be used.

  As shown in FIG. 1, the base 12 is suspended and supported near the ceiling above the dismantling processing line (not shown), and a plurality of driving devices 19 and 19 (however, FIG. 1, two driving devices 19 are shown), and the lower ends of the wires 20 and 20 extending in the up and down direction for vertically moving the base 12 up and down by the winding operation are fixedly attached. .

  When the driving devices 19 and 19 are driven so as to feed out the wires 20 and 20, the base body 12 located above the dismantling processing line covers the entire processing vehicle 11 conveyed along the dismantling processing line from above. To descend. When the base 12 covers the entire processing vehicle 11 from above, a substantially sealed space S is formed around the processing vehicle 11. Further, when the driving devices 19 and 19 are driven so as to wind up the wires 20 and 20, the base 12 is raised and positioned at the original position, that is, above the dismantling processing line.

  The driving devices 19 are driven manually by an operator operating control means (not shown), or the control means detects and determines the position of the processing vehicle 11 on the dismantling processing line. It is configured to be performed automatically. Further, the lifting means for lifting and lowering the base 12 may be a set of the drive device 19 and the wire 20. Further, such lifting means is not limited to the above-described wire type, and is configured to raise and lower the base 12 using another mechanical type, hydraulic type, pneumatic type, or the like. May be.

  Further, a lower end portion of a flexible duct (hereinafter referred to as a duct) 21 that expands and contracts as the base body 12 moves up and down is joined to a joint portion between the base body 12 and the wires 20 and 20 in a state where the wires 20 and 20 are contained. In addition, an insertion hole (not shown) is formed. Thereby, the gas in the substantially sealed space S formed by lowering the base body 12 can flow into the duct 21 through the insertion hole.

  As described above, the base 12 is supported in a state of being suspended above the processing vehicle 11 by the wires 20, 20 wound or fed by the driving devices 19, 19, and is supported by the portions supported by the wires 20, 20. Since the duct 21 is a suspended type, it does not take an installation place on the line side. Therefore, it is possible to dispose of the airbag device on the dismantling processing line, and work efficiency is further improved.

  Next, the collection means 13 will be described. The recovery means 13 includes the duct 21 described above, a filter 22 that is disposed on the upstream side of the duct 21 and removes dust and odors (including toxic substances) in the gas transferred through the duct 21, and a base body. 12 and an exhaust device 23 for sucking and discharging the gas in the substantially sealed space S formed by 12. The duct 21, the filter 22, and the exhaust device 23 are disposed near the ceiling near the drive devices 19 and 19.

The exhaust device 23 is configured to be driven and controlled by a control device (not shown) when the airbag device of the processing vehicle 11 is activated. Further, the control device passes a set time set in advance after driving the exhaust device 23, or is based on a detection value of a detection means (not shown) provided at the outlet of the filter 22. When it is determined that the gas inside has been sufficiently collected and purified, the exhaust device 23 is immediately stopped.
Note that the airbag device of the processing vehicle 11 may be activated after the exhaust device 23 is driven.

  Next, an air bag processing method for performing processing by operating the air bag device while being mounted on the vehicle using the base body 12 and the recovery means 13 configured as described above will be described with reference to FIG. .

  The processing vehicle 11 transported according to the dismantling processing line is transported until it reaches a predetermined position that is processed by operating the airbag device. As a result, the processing vehicle 11 on the dismantling processing line is arranged below the base 12 supported above the dismantling processing line by the wires 20 and 20 suspended from the vicinity of the ceiling.

  And the wiring for operating an airbag apparatus by the remote operation from the vehicle exterior is connected to the operation circuit of the airbag apparatus mounted in the process vehicle 11. FIG.

  Next, the driving devices 19 and 19 are driven so as to feed out the wires 20 and 20, and are lowered until the base 12 covers the entire processing vehicle 11 substantially completely. Thereby, a substantially sealed space S is formed inside the base 12, that is, around the processing vehicle 11.

Then, a current is passed through the operation circuit of the airbag device via the wiring, and the airbag device of the processing vehicle 11 is collectively operated in the substantially sealed space S isolated from the outside by the base 12. In the state in which the airbag device is activated, the exhaust device 23 is driven to generate a negative pressure flow in the substantially sealed space S. Thereby, as the gas in the substantially sealed space S is sucked from the upper part of the base body 12, the explosion sound generated during the operation of the airbag device is attenuated and the developed gas is recovered.
It should be noted that the vehicle state such as the following (1) to (5) can be set in the case of collecting the developing gas. That is,
(1) When considering the recovery of the developing gas, it is more desirable to fully open the glass.
(2) Doors and rear gates may be opened instead of glass.
(3) If noise is important, it is desirable to fully close the glass.
(4) In order to balance noise and recovery gas recovery, the glass may be in an intermediate position, for example, slightly opened from the fully closed state.
(5) Connecting the wiring for operating the airbag device by remote control from the outside of the vehicle means connecting the dedicated device to the integrated unit such as the ECU, and automatically connecting it to the ECU during the process. A glass may be opened and closed by sending a signal.

  By the way, when the base 12 covers the entire processing vehicle 11, a slight gap may be generated between the base 12 and the floor surface. However, when the exhaust device 23 is driven, the inside of the substantially sealed space S is in a negative pressure state, so that an air flow is generated from the slight gap between the base 12 and the floor to the inside of the sealed space S. Therefore, the gas in the substantially sealed space S does not leak from such a gap. The recovered developing gas is purified by the filter 22 and then released into the atmosphere.

  When the recovery and purification of the developing gas are completed, the driving of the exhaust device 23 is stopped. Then, the drive devices 19 and 19 are driven so as to wind up the wires 20 and 20, and the base body 12 is raised and separated from the processing vehicle 11 after the operation of the airbag device is completed.

  And the disposal process of the airbag apparatus of the processing vehicle 11 is continuously performed by repeating the processing process of the airbag apparatus described above.

  Thus, according to the present embodiment, as shown in FIG. 1, the processing is performed by operating the airbag device of the processing vehicle 11 in the substantially sealed space S formed by the base body 12. The plurality of airbag devices attached to the can be collectively processed. Moreover, since the processing vehicle 11 is covered with the base 12 that can be raised and lowered, the working time is shortened and the processing vehicle 11 can be processed continuously, so that the work efficiency can be improved.

Further, since the gas in the substantially sealed space S is collected by the collecting means 13, a negative pressure flow is generated in the substantially sealed space S, and the explosion sound generated when the airbag device is operated is attenuated. And the developing gas is recovered. As a result, sufficient soundproofing and smokeproofing measures can be taken for workers and the surrounding environment.
Furthermore, the base body 12 is supported in a state where it is suspended above the processing vehicle 11 having an airbag device, and a duct 21 is provided at a support portion where the base body 12 is suspended, that is, a portion supported by the wires 20 and 20. Because it is a continuous hanging type, it does not take up installation space. Accordingly, no equipment costs are incurred, and the air bag apparatus can be discarded on the dismantling process line, so that the work efficiency can be further improved.

  In addition, in the expansion | deployment shape of the base | substrate 12 of a present Example, although formed so that the processing vehicle 11 whole may be covered, it is not limited to this. That is, when an airbag device that inflates and deploys toward the outside of the vehicle body, for example, a front hood airbag is not attached, as shown in FIG. 3, the base 12 that covers the cabin of the processing vehicle 11 excluding the front hood. It may be configured to have '. Also with this configuration, it is possible to obtain the same operational effects as the operational effects of the airbag processing apparatus and the processing method described above.
