Description

  The present invention relates to a wiping member and a vehicle wiping device, and more particularly, to a wiping member and a vehicle wiping device including the wiping member.

  2. Description of the Related Art Conventionally, in cleaning a vehicle such as an automobile or a train, the surface of the vehicle is wiped and dried by an air blow and a vehicle wiping device after the surface of the vehicle is washed with water.

  In addition, in checking the water resistance during manufacture of a vehicle, the vehicle surface is wiped and dried by a vehicle wiping device after water is sprayed on the vehicle surface.

  Such a vehicle wiping device is provided with a water-absorbing woven fabric or nonwoven fabric as a wiping member, and the wiping member contacts and slides on the vehicle surface, thereby wiping the vehicle surface.

  On the other hand, using only a woven fabric or a nonwoven fabric as the wiping member results in insufficient adhesion to the vehicle surface, resulting in poor wiping performance.

  Therefore, for example, a cloth body made of a rectangular plate-shaped thin curtain article, a mounting cylinder connecting the upper part of the cloth body, and a weight such as fishing lead and a wool-shaped tuft mounted on the lower part of the cloth body are provided. A water-containing wiping tool provided has been proposed (for example, see Patent Document 1 (FIG. 11)).

JP-A-8-253111

  However, as described in Patent Literature 1, simply attaching the weight and the thread-shaped tuft to the lower part of the cloth body has a problem that the adhesion to the vehicle surface is not sufficient and the wiping property is poor.

  The present invention relates to a wiping member having excellent wiping properties and a vehicle wiping device including the wiping member.

  The present invention [1] is a wiping member for wiping the vehicle surface by contacting and sliding on the vehicle surface, the rubber sheet having a drape property, and the one side of the rubber sheet, A water-absorbing cloth provided so as to make contact therewith, and a wiping member.

  The present invention [2] includes a vehicle wiping device including: the wiping member according to the above [1]; and a fixing member that fixes the rubber sheet so that the water-absorbing cloth of the wiping member contacts a vehicle surface. In.

  The wiping member of the present invention is a wiping member for wiping the vehicle surface by contacting and sliding on the vehicle surface, and having a drapeable rubber sheet, and a rubber sheet having one surface side capable of contacting the vehicle surface. And a water absorbing cloth to be provided.

  With such a wiping member, the water-absorbing cloth adheres to the vehicle surface according to the drape property of the rubber sheet, so that the vehicle surface can be wiped well.

  Therefore, the vehicle wiping device including the wiping member described above has excellent adhesion between the wiping member and the vehicle surface, and can satisfactorily wipe the vehicle surface.

FIG. 1 is a schematic diagram of a manufacturing / inspection flow of a vehicle, FIG. 1A shows a plan view, and FIG. 1B shows a side view. FIG. 2 is a schematic diagram showing one embodiment of the vehicle wiping device of the present invention. FIG. 3 is a schematic diagram illustrating an embodiment of a wiping member provided in the vehicle wiping device illustrated in FIG. 2.

1. 1. Manufacturing / Inspection Flow In FIG. 1, after a car 10 as a vehicle is manufactured in a manufacturing process A, the car 10 is conveyed by a conveyor 12 in a predetermined direction (from the left side of the paper of FIG. 1 to the right side of the paper of FIG. 1). The function is inspected in the function inspection step B, and thereafter, the appearance is inspected in the appearance inspection step C.

  In the manufacturing process A, first, various members such as a steel plate member, a resin member, an electronic device member, and a driving member are combined, and the automobile 10 is manufactured according to a normal method.

  Next, in a function inspection step B, various functions of the automobile 10 are inspected. The inspection items include, for example, an airbag inspection, a lamp inspection, a drum inspection, a brake inspection, a lowering inspection, a water immersion inspection (shower test), and the like.

  In the function inspection process B, if the automobile 10 is wet, the inspection efficiency such as a brake inspection and a lowering inspection decreases. Therefore, preferably, various functions are inspected using the automobile 10 in a dry state. From such a viewpoint, the inspection that wets the automobile 10, that is, the water resistance inspection is performed at the end of the function inspection process B.

  In the water resistance test, first, the vehicle 10 is transported by the conveyor 12 and the vehicle 10 enters the shower room 13. Then, the shower device 14 attached to the shower room 13 sprays water onto the vehicle surface (specifically, the upper surface, front and rear surfaces, both side surfaces, etc. of the automobile 10 (the same applies hereinafter)) to wash the vehicle surface with water. I do.

  Next, the car 10 is transported by the conveyor 12, and the car 10 enters the drying chamber 15. Then, an airflow is generated around the automobile 10 by an air blow device 16 as an airflow generation source attached to the drying chamber 15 to dry the vehicle surface. Thereafter, the presence or absence of water leakage into the cabin is checked, and the water resistance is evaluated.

  However, depending on the transport speed of the automobile 10, the airflow from the air blow device 16 alone may not sufficiently dry the vehicle surface.

  For this reason, a vehicle wiping device 1 for wiping water droplets on the surface of the vehicle is installed at the exit of the drying chamber 15 so that the surface of the vehicle can be wiped as the vehicle 10 is conveyed. After passing through the vehicle wiping device 1, the automobile 10 is checked for water leakage into the passenger compartment. Thereafter, in the appearance inspection process C, the worker is visually checked for irregularities and scratches. (Appearance inspection).
