Description

  The present invention relates to an improvement in a paint peeling apparatus for parts used in automobiles and the like.

In recent years, there has been a demand for improvement in awareness of environmental problems and resource reuse, and there has been an active movement to recycle synthetic resin products. In the automobile industry, many synthetic resin products are used, and bumpers and side protection malls are examples.
In particular, bumpers composed of thermoplastic resins such as polypropylene resins are used in large quantities because they have been collected from defective products or scrapped vehicles that are considered nonconforming in the manufacturing process. There was a request to do.

  However, the surface of the bumper is coated with a thermosetting resin paint such as polyester urethane, so if you recycle it with some of this paint remaining, the paint pieces will be mixed into the synthetic resin. Therefore, there was a problem that the fluidity was hindered and the cause of molding failure was caused.

  Therefore, conventionally, methods and apparatuses for removing paint so as not to remain on the surface of the bumper have been proposed. For example, in Patent Document 1, a resin member having a coating film is rolled between rolls facing each other and having different rotational directions and rotational peripheral speeds, thereby applying shear shear stress between the coating film and the resin material. A coating / peeling device for a coating resin product for stripping a coating film from a material, comprising a pressing means for biasing the rolls so as to approach each other with a relatively constant biasing force. Is disclosed.

However, in the paint peeling apparatus described in Patent Document 1, it is not easy to peel off the coating film applied to the bumper formed in a three-dimensional shape having unevenness only by the frictional force between the rolls. was there.
Moreover, in the coating peeling apparatus described in Patent Document 1, it is difficult to sequentially peel off the coatings of bumpers having different plate thicknesses because the distance between the rolls is constant.

Hereinafter, the effect | action of the coating peeling apparatus 10 which concerns on this Embodiment is demonstrated using an accompanying drawing.
As shown in FIG.1 and FIG.2, when using the coating peeling apparatus 10 which concerns on this Embodiment, the bumper P made from a synthetic resin which has a coating film was spaced apart from the part rolling part 11 side by the space | interval dimension of 200 mm. Between the roller 16a and the roller 17a, the coating film surface is inserted upward.
At this time, as shown in FIGS. 1 and 2, in the component rolling unit 11 according to the present embodiment, the sensor unit 14a is provided above the roller 16a. When it detects, the control part 15a operates the hydraulic piston part 18a, the roller 16a is arrange | positioned in proximity with the roller 17a, and the bumper P is rolled.

Since the rollers 16a and 17a according to the present embodiment roll the bumper P while rotating, the bumper P rolled by the rollers 16a and 17a is conveyed to the rollers 16b and 17b constituting the press unit 13b.
Subsequently, when the sensor part 14b provided above the roller 16b detects the bumper P conveyed, the control part 15b operates the hydraulic piston part 18b, and arranges the roller 16b close to the roller 17b. The bumper P is rolled. The rolled bumper P is conveyed to the rollers 16c and 17c constituting the press unit 13c.

  Subsequently, when the sensor unit 14c provided above the roller 16c detects the conveyed bumper P, the control unit 15c activates the hydraulic piston unit 18c, and the roller 16c is disposed close to the roller 17c. And bumper P is rolled.

Therefore, the rolling process and the conveying process of the vehicle component P can be performed at the same time, and as a result, the operation cost can be reduced.

Furthermore, in the paint peeling apparatus 10 according to the present embodiment, when the sensor parts 14a, 14b, 14c detect the bumper P, the rollers 16a, 16b, 16c are driven by the hydraulic piston parts 18a, 18b, 18c. Is placed in close proximity to the bumper P, and then biased, the bumper P sandwiched between the rollers 16a, 16b, 16c and the rollers 17a, 17b, 17c is rolled, so that the bumper P is pressed. When transported to the parts 13a, 13b, 13c, the bumper P can be reliably rolled.
In particular, in the component rolling unit 11 according to the present embodiment, even when a bumper having a non-uniform thickness having a complex shape is continuously rolled, it can be reliably rolled, As a result, it is possible to provide a paint stripping device for automobile parts that can strip and remove the coating film more effectively.
In particular, when the sensor units 14a, 14b, and 14c according to the present embodiment are configured to detect the thickness of the bumper P, the rollers 16a, 16b, and 16c and the roller 17a are provided for each bumper having a different thickness. , 17b, 17c can be adjusted, and the rolling can be reliably and effectively rolled.

  Furthermore, in the paint peeling apparatus 10 according to the present embodiment, when the sensor units 14a, 14b, 14c provided for the press units 13a, 13b, 13c detect the bumper P, the control unit 15a 15b, 15c controls the press portions 13a, 13b, 13c corresponding to the detected positions, and the bumper P is rolled. For example, the bumper P is rolled by the press portion 13a and then rolled by the press portion 13b. In this case, the press part 13b can be controlled according to the rolling situation of the bumper P, and the bumper P can be rolled reliably.

  The present invention is widely applicable to paint peeling devices and has industrial applicability.
