Description

[Detailed description of the invention] <Industrial field of application> The present invention removes long and thin pieces of waste such as hair and yarn that are deeply and strongly entangled in the flocked part of a flocked floor mat whose surface is formed in the shape of a cut pile. Regarding the removal device, the long and thin debris that has been scraped off from the flocked surface of the floor mats and attached to the rotating scraping brush is scraped off with comb teeth and removed through the debris guide duct, making the removal of this long and thin debris efficient and powerful. Provide what you can do.

<Prior art and its problems> Flocked floor mats that have been used for a long time and have absorbed dust and the like are generally recycled in the following manner.

(1) Perform rough treatment by removing soil, gravel, coarse dust, etc. adhering to the pine surface by washing with water, or by cleaning while performing the removal work.

(2) Dry the floor mat.

(3) Finishing is performed by removing long and thin pieces of hair, thread, and other debris that are tightly entangled on the flocked surface of the floor mat.

(4) The floor mat is electrically charged to make it easier for the floor mat to absorb dust, etc. from footwear, etc.

For example, as shown in Japanese Utility Model Publication No. 60-26878, a conventional floor mat dust removal device cleans a floor mat guided by guide rollers with a channel brush soaked in detergent solution, and then sprays high-pressure water from a waterproof pipe. However, there are some that use separate channel brushes to wash with water and remove sand and mud.

However, the above-mentioned conventional technology performs (1) rough treatment in the floor mat regeneration process, but does not perform (3) finishing treatment.

By the way, in the regeneration process of floor mats, the above (4)
As shown in the figure, since the final charging process is carried out,
Among the dust that has adhered to the mat due to long-term use,
In particular, elongated waste pieces such as hair waste and thread waste, which are easily charged, are electrically attracted to the deep part of the charged flocked part and become strongly entangled, making it difficult to remove them.

For this reason, when regenerating flocked floor mats, the rough treatment in (1) cannot remove long and thin debris, so the finishing treatment in (3) becomes necessary.

However, in this finishing process, even if done mechanically using a brush, the elongated debris gets entangled with the brush and is difficult to remove, and the debris removal efficiency gradually decreases. The reality is that we are getting used to it.

On the other hand, in Japanese Utility Model Publication No. 55-32133, a conveyor belt connected to a vacuum duct is run below a rotating brush, the surface of plywood etc. is removed with the rotating brush, and the dust is removed from a large number of suction ports provided in the conveyor belt. Technical matters have been disclosed to prevent dust from re-adhering to plywood etc. by suctioning it.

Therefore, it is conceivable to combine the above-mentioned technology with the cleaning part of the conventional technology to suction the elongated debris stuck deep inside the flocked area while washing the flocked surface of the floor mat with water. Not only is it difficult to reach the area, but the debris becomes wet and sticks to the flocked area, so there is a great possibility that it will be even more difficult to remove.

The technical problem of the present invention is to automatically machine finish the finishing process (3) above, which is conventionally done manually, and to also reliably remove fine particles.

<Means for Solving the Problems> Means for achieving the above-mentioned problems will be described below using drawings corresponding to embodiments.

That is, in the present invention, a rotary scraping brush 1 for scraping off elongated debris entangled on the flocked surface of a flocked floor mat M is supported on a support frame 3 so as to be rotatably driven around a left-right axis 2, and the flocked floor mat M is rotatably scraped. Conveying device 4 that passes through the upper circumference of the removing brush 1
are provided over the front and back sides of the upper part of the rotary scraping brush 1, and the comb teeth 5 are used to remove elongated debris scraped from the flocked surface of the flocked floor mat M onto the rotary scraping brush 1 from the rotary scraping brush 1. The comb teeth 5 are inserted into the lower circumference of the scraping brush 1, and the comb teeth 5 are moved in the direction A perpendicular to the rotating direction so that the tip end 5a approaches the upper side of rotation of the rotating scraping brush 1 than the base end 5b. The entire length of the rotary scraping brush 1 is oriented so that the scrap guide duct 7 guides the elongated debris scraped off from the rotary scraping brush 1 by the comb teeth 5 from the lower space of the rotary scraping brush 1 to the debris collection container 6. A fan 8 is installed in the waste guide duct 7, and is provided along the lower space extending through the waste guide duct 7. The rotary scraping brush 1 and the conveying device 4 are connected to the prime mover 10, and the rotary scraping brush 1 and the conveying device 4 are driven by the prime mover 10, and the fan 8 is operated. While the flocked floor mat M is being transported by the conveying device 4 with its flocked surface facing downward, elongated debris entangled with the flocked surface of the flocked floor mat M is scraped off from the flocked surface of the flocked floor mat M by the rotary scraping brush 1. Comb teeth 5 that enter this while maintaining the inclination angle
This feature is characterized in that the waste is combed and dropped into the waste guide duct 7, and the waste is collected from the waste guide duct 7 into the waste collecting container 6 by the wind generated by the fan 8.

<Effect> Flocked floor mat M recovered after long-term use
After washing and cleaning, the material is dried and sent to the elongated waste removal device.

The flocked floor mat M is transported by the transport device 4 with the flocked surface facing downward, and the rotary scraping brush 1 scrapes off elongated debris entangled with the flocked surface.

The long and thin debris scraped off with the brush above should be removed with brush 1.
However, it is removed from the brush 1 by the comb teeth 5 that protrude at an angle of inclination to the brush 1.

In this case, the comb teeth 5 are arranged in a direction A perpendicular to the rotational direction so that the tip end 5a is closer to the upper side of the rotation of the rotary scraping brush 1 than the base end 5b.
Brush 1
The brush rubs against the other brushes, increasing the downward scraping force and powerfully removing long and thin pieces of debris entangled with the brushes.

The elongated debris removed from the rotating scraping brush 1 by the comb teeth 5 is sucked into the debris guide duct 7 provided along the space below the brush 1, and then blown toward the debris container 6. Sent.

<Effect of the invention> Since the elongated waste is scraped off from the rotating scraping brush with the comb teeth and removed to the waste guide duct, the elongated waste does not stay in the rotating brush or the comb teeth, and is constantly refluxed and removed from the rotating scraper. A removal brush can be used to remove debris from the flocked surface of flocked floor mats.

For this reason, long and thin pieces of waste such as lint, hair, etc. entangled in the pine can be removed continuously and strongly for a long period of time.
Floor mats can be finished easily, efficiently, and neatly.
