Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention removes excess pile from a flocked product (hereinafter referred to as a work) in which piles are flocked, for example, a work such as a grass run or a door trim and removes excess pile. The present invention relates to a collecting method and a surplus pile removing and collecting device.

[Prior Art] In the manufacturing process of works such as glass runs and door trims in which a large number of piles of hair are planted on the surface of the base material, after the piles are transplanted onto the base material, they are not adhered to the base material but adhered between the piles. A surplus pile remains. Then, it is necessary to remove and collect the surplus pile in order to improve the product appearance and to improve the pile yield. Therefore, as shown in FIG. 4, the conventional surplus pile removing and collecting apparatus supplies air to the air blower 32 by the air compressor 31, and the air nozzle 33
An air blow method is adopted in which air is ejected from the air to blow away excess pile adhering to the work W, and the excess pile blown is collected by the dust collector.

Further, in Japanese Patent Publication No. 57-56378, as shown in FIG. 5, a strip-shaped partition plate 36 extending in the longitudinal direction is arranged on the inner peripheral surface of the cylindrical drum 35 so as to be divided into equal parts. In the drum 35, put a pile between the partition plates 36 and rotate the drum 35,
There is disclosed a pile collecting and conveying device of a type in which piles are dropped and the work W passing through the drum 35 is flocked, and excess piles that have not been flocked are dropped onto the partition plate 36 and the piles are reused.

[Problems to be Solved by the Invention] However, in the air blow method, the air ejected from the air nozzle 33 diffuses until it reaches the surface of the work W, and a sufficient excess pile removing pressure cannot be obtained. Therefore, it is conceivable to increase the pressure, but since there is a limit to the increase in the air ejection pressure from the viewpoint of cost or the amount of pile collection, the conventional apparatus reliably removes the excess pile adhering to the work W. I couldn't. For this reason, the appearance quality of the work W is deteriorated, and the amount of excess pile collected is decreased, which causes a problem in pile yield. Further, there is a problem that the surplus pile blown off by the air blow is scattered to the outside of the device by the air leakage from the dust collector 34 itself or due to the air leakage from the dust collector 34 itself, which deteriorates the environment in the factory.

The apparatus disclosed in Japanese Patent Publication No. 57-56378 does not have any means for removing the surplus pile adhering to the work W.

An object of the present invention is to provide a surplus pile removing and recovering method which can surely remove surplus piles attached to a work, improve the yield of piles, and do not deteriorate the environment in the factory.

Another object of the present invention is to reliably remove the surplus pile adhering to the work, and also improve the yield of the pile,

It comprises a step of spraying pressured water to wash the work to remove the excess pile from the work, and a step of collecting the wash water and collecting the excess pile in the wash water with a filter.

The surplus pile removing / collecting device of the second invention is to remove the surplus pile from the work by spraying pressure water from a plurality of nozzles arranged so as to surround the work to which the flock is applied, to wash the work. A pressure water jetting device having a plurality of nozzles for cleaning, and a filter located below the pressure water jetting device for filtering the washing water through a filter to collect an excess pile in the washing water. And a pump device for pumping the water in the storage tank to the pressure water jetting device.

[Operation] In the first invention, the pressure water removes the excess pile from the work by cleaning the work, and
The filter filters and collects the excess pile from the wash water containing the excess pile.

In the second invention, the pump device pumps the water in the storage tank to the pressure water injection device, and the pressure water injected from the nozzle of the pressure water injection device cleans the work to remove the excess pile from the work. The filter of the filtering device filters and collects the excessive pile from the wash water containing the excessive pile, and a water circulation path is formed in which the water that has passed through the filtering device is stored again in the storage tank.

[Embodiment] A surplus pile removing and collecting apparatus according to an embodiment of the present invention will be described below with reference to FIGS. In this device, for example, as shown in FIG. 3, a continuous flocked product in which a large number of piles P are planted (flocked grass run in this example).
The excess pile of the work W is removed and collected.

As shown in FIG. 1, a cylindrical casing 1 is divided by a partition wall 2 into two chambers, an injection chamber 3 and a drying chamber 4, and the central portion of each of the right wall 1a, the left wall 1b and the partition wall 2 of the casing 1. An introduction hole 5, a lead-out hole 6 and a transport hole 7 for inserting the work W are formed therein. A sealing structure (not shown) such as a curtain made of rubber pieces is provided in at least the introduction hole 5 among the introduction holes 5, the derivation holes 6, and the transport hole 7 so that the pile P is not scattered from the casing 1. ing. In the injection chamber 3, two hollow ring-shaped pressure water injection devices 8 each having an insertion hole 9 for inserting the work W in the center are arranged side by side in the longitudinal direction of the casing 1. Each pressure water injection device 8 has a ring portion 11 having an introduction chamber 10 therein, and six nozzles 12 arranged at equal intervals in the circumferential direction of the ring portion 11 on the introduction hole 5 side of the casing 1. Consists of. Each nozzle 12 is the introduction chamber 10
And is directed to the work W as shown in FIG.

The pipe 15 of the first pump 14 submerged in the water A stored in the storage tank 13 is connected to the introduction chamber 10 of the ring portion of each pressure water injection device 8, and the water in the storage tank 13 is The pump 1 is pressure-fed to the introduction chamber 10 through the pipe line 15, and this water A is jetted from each nozzle 12 as pressure water to wash and remove the excess pile adhering to the work W.

A water tank 17 is provided below the injection chamber 3 of the casing 1 via a duct 16 that also serves as a bottom wall of the casing 1, and a first filter 18 made of, for example, a nylon cloth bag is provided in the water tank 17. The cleaning water D, which is disposed and contains the excess pile removed from the work W, receives the duct 16 and the first filter.
It passes through 18 and is stored in the water tank 17. A second pump 19 is immersed in the wash water D in the water tank 17, and the second pump 19 is connected via a pipe 20 to a second filter 21 located above the storage tank 13. Furthermore, the second
A third filter 22 and a fourth filter 23 are left below in order between the filter 21 and the storage tank 13. As the filters 18, 21, 22, 23, those having a narrower mesh are used in the order from the first filter 18 to the fourth filter 23.
For example, the rate of removing and collecting the excess pile of the work W in which the 3-denier pile P (length 0.8 mm) is planted, the first filter 18 is 60 mesh, the second filter 21 is 80 mesh, and the third filter is
The filter 22 is 100 mesh, and the fourth filter 23 is 150 mesh.

The water tank 17 and the first to fourth filters 18, 21, 22, and 23 constitute a filtering device F that filters and collects the excess pile from the cleaning water D containing the excess pile removed from the work W.

In the drying chamber 4 of the casing 1, the pressure water jetting device 8
Two air blowers 24 having the same configuration as the above, each having an insertion hole 25 for inserting a workpiece W and an air nozzle 26, are arranged side by side in the longitudinal direction of the casing 1, and each air blower 24 has a conduit 27.
The air compressor 28 is connected via. Then, air is supplied from the air compressor 28 to the pipe 27 and the air blower.
The work W is sprayed through the 24 air nozzles 26, and the water droplets adhering to the work W are blown off to perform drying.

Next, a method for removing and collecting the excess pile from the work W by using the excess pile removing and collecting apparatus configured as described above will be described.

First, the work W on which continuous flocking is applied is introduced into the casing 1 from the introduction hole 5 of the casing 1, and the insertion holes 9 of both pressure water jetting devices 8, the conveying hole 7, and the insertion holes 25 of both core blowers 24 are inserted. The work W is led out to the outside of the casing 1 from the lead-out hole 6 via the lead-out hole 6. Then, the work W is conveyed by the conveying means (not shown).
Is conveyed from the introduction hole 5 side of the casing 1 to the discharge hole 6 side, and the first pump 14 is driven. Then, the storage tank
The water A of 13 is introduced through the pipe 15 into the introduction chamber 10 of the pressure water injection device 8.
It is pressure-fed inward, and pressure water is jetted from the nozzle 12 toward the work W, and the excess pile adhering to the work W is washed and removed by this pressure water.

The cleaning water D containing the excess pile washed and removed from the work W passes through the duct 16 to the first filter 18 in the water tank 17, and at that time, most of the excess pile is removed by the coarsest first filter 18. Preliminarily filtered and recovered. Next, the second
When the pump 19 is driven, the wash water D which has passed through the first filter 18 and still contains the excess pile is supplied to the second passage via the pipe 20.
It is discharged to the filter 21, passes through the third filter 22 and the fourth filter 23, and is stored in the storage tank 13. The surplus pile contained in the wash water D is reliably filtered and collected while passing through the second to fourth filters 21 to 23 whose meshes are gradually narrowed, and the fresh water A containing no surplus pile in the storage tank 13. Is stored.

Thereafter, the same procedure as described above is repeated to form a circulation path for the water A in the storage tank 13 to be stored again in the storage tank 13 via the pressure water injection device 8 and the filtering device F.

On the other hand, the work W from which the excess pile has been removed by the pressure water jetting device 8 is conveyed to the drying chamber 4 of the next stage, and is driven at the same time as the driving of the first pump 14 by the air compressor 28.
The high-pressure air ejected from the air blower 2 via the air nozzle 26 scatters and removes water droplets adhering to the work W, and the work W is dried. And the work W after drying
Is led out of the casing 1 through the lead-out hole 6, and the work of removing and collecting the surplus pile of the work W is completed.

In the method for removing and recovering the excess pile, the excess pile is removed by the pressure water whose degree of diffusion is lower than that of air, so that a sufficient excess pile removal pressure can be obtained. The surplus pile attached to the work W can be reliably removed. Therefore, the appearance quality of the flocked product can be improved.

In addition, the excess piles contained in the wash water D are sequentially collected by filtration by the first to fourth filters 18, 21, 22, 23, so that the filters 18, 21, 22, 23 are clogged. None, and the surplus pile in the wash water D is reliably collected by filtration. Therefore, the yield of piles is remarkably improved as compared with the conventional air blow method.

Further, since the surplus pile in the cleaning water D can be reliably filtered and recovered by the first to fourth filters 18, 21, 22, 23, a circulation path of the water A that circulates from the storage tank 13 to the storage tank 13 again is formed. Therefore, the cost for removing and collecting the excess pile can be reduced.

In addition, since the excess pile is removed and recovered by using the water A, the excess pile removed from the work W does not scatter to the outside of the excess pile removing and recovering device, and the environment in the factory does not deteriorate. .

The present invention is not limited to the above-described embodiments, but may be modified and implemented as follows, for example, without departing from the spirit of the invention.

(1) In the above embodiment, the air blower 24 is used as a means for drying the work W. However, a heat drying device such as a heater is used, or a special means for drying the work W is provided. Alternatively, the work W may be naturally dried.

(2) In the above embodiment, the filter F having the first to fourth filters 18, 21, 22, and 23 having four-level coarseness is used, but the excess pile is completely removed without causing clogging. The number of filters is increased or decreased as appropriate within the range where filtration and recovery are possible. Alternatively, the coarseness of each filter is changed appropriately.

(3) In the above embodiment, the first filter in the filtering device F
18 and the second to fourth filters 21 to 23 are arranged at different positions, and a pipe for sending the cleaning water D by using the second pump 19 is shown between them. If it is formed by superposition and positioned below the pressure water jetting device 8, the water tank 17
And the storage tank 13 can be shared, the second pump 19 and the pipeline 20 can be eliminated, and the surplus pile removing and collecting apparatus can be made compact and can be manufactured at low cost.

(4) The number of pressure water jetting devices 8 or the number of nozzles 12 of each pressure water jetting device 8 is appropriately changed.
