Description

[0001] Equipment of Continuous Flocking Process [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flocking carpet flocking process system, and more particularly, to a flocking carpet flocking process in which, during a flocking carpet manufacturing process, a series of flocking processes for planting yarns on a substrate is continuously performed Flocking process equipment.

Flocking carpet means a carpet manufactured by a flocking method in which a fiber made of nylon is vertically erected on a substrate made of glass fiber or nonwoven fabric by using static electricity and densely molded (see, for example, Patent Document 1 Reference).

The manufacturing process of the flocking carpet includes a flocking process for manufacturing a carpet fabric by largely inserting a yarn on the base material, a printing process for printing a predetermined color and pattern on the surface of the fabric, (See, for example, Patent Document 2).

The flocking step during the manufacturing process of such a flocking carpet includes a step of vertically standing a yarn using static electricity to form an adhesive on an adhesive applied to the substrate, a step of putting the fabric (base + yarn) A process of fixing the formed yarn by hardening, a process of cooling the fabric heated in the dryer, and a process of winding the fabric on the core after cooling.

As in the general manufacturing process, the sequencing of the flocking process leads to productivity improvement by eliminating the neck process, and productivity improvement is advantageous to lower the cost of the carpet to secure price competitiveness, It is also meaningful that it can be offered at a price.

However, since the characteristics of the carpet flocking process are very different from each other and the time required for each process is greatly different as in the process described above, it is difficult to carry out the carpet flocking process at a constant speed throughout the entire process.

Particularly, the conventional cooling process is performed in such a manner that the raw material from the dryer is left at room temperature as it is and is cooled naturally. However, such a cooling method requires more time than other processes, which is one reason why the sequencing process is not possible. There is also a case where a large area is required to cool the fabric.

Further, in the conventional flocking process, in the process of placing the yarn on the substrate (hereinafter referred to as " electrodeposition process "), the yarn falling from the hopper toward the substrate must be uniformly distributed at all times, You can get carpet of. Therefore, in the electrodeposition step, it is necessary to appropriately adjust the time required to uniformly distribute and drop the yarn and the time required for the dropping yarn to be stuck to the adhesive layer on the surface of the fabric, Product quality can also be improved.

1, the flocking process equipment according to the present invention includes a far-end feeding stage 100 having a feed roller 110 wound with a substrate 1, a base material 1 An adhesive application stage 140 for applying an adhesive to the surface of the base material 1 while transferring the base material 1 to the base material 1; A drying stage 300 for drying the fabric (base material + yarn) on which the yarn is stuck to the substrate 1 to fix the yarn by hardening the adhesive layer, and a drying stage 300 for passing the dried fabric 2 through the cooling unit 420 A forced cooling stage 400 for forced cooling by a separate coolant and a winding stage 500 for winding the cooled fabric 2 around the core tube 510 are sequentially arranged so that the material 2 ) Is repeated for a series of steps It is.

Between the feed roller 110 and the adhesive application stage 140 there are provided an ejector 120 for pulling out the substrate 1 wrapped around the feed roller 110 as shown in Figure 1, It is possible to smoothly carry out the continuous process by arranging the lowering device 130 which accumulates the product before being conveyed to the stage 200 to smooth the supply, maintains the appropriate tension, and prevents the process from stopping during the change of the substrate.

Further, when a low-tension machine 600 is disposed between the forced cooling stage 400 and the winding stage 500 to accumulate the raw fabric 2 before it is conveyed to the winding stage 500, Thereby helping to realize the sequencing process.

With reference to Figs. 2 to 6, the construction of each stage constituting the continuous flocking process equipment will be described.

As shown in FIG. 2, the far-ulteed feeding stage 100 is provided with a feed roller 110 wound with the substrate 1.

The substrate 1 wound around the feed roller 110 is unwound by the ejector 120 and introduced into the lower tray 130 and accumulated.

A plurality of rollers 131 are vertically arranged in a zigzag manner on the lower machine 130. The base material 1 is accumulated by a predetermined length while passing between the plurality of rollers 131, so that the process can be prevented from being stopped when the base material 1 is exchanged.

3, the adhesive application stage 140 applies an adhesive to the upper surface of the substrate 1 to a predetermined thickness before the substrate 1 enters the electrophoretic deposition stage 200. As shown in Fig. The adhesive application stage 140 has a knife and an adhesive supply nozzle capable of adjusting the thickness of the adhesive layer through adjustment of the gap with the upper surface of the substrate 1. [

The electrophoretic deposition stage 200 includes a device for transferring a substrate 1 to which an adhesive is applied, a device for dropping the yarn on the upper surface of the substrate 1 as snow, a charging device for charging a dropped yarn by generating static electricity, An electrostatic induction device for erecting the yarn, and a vibration device for assisting the formation of the yarn.

The conveying conveyor 210 is composed of a mesh conveyor in the form of a net and circulated by the driving source 211 and the sprocket 212. The substrate 1 is placed on the upper surface of the conveying conveyor 210 and conveyed at a predetermined speed.

A feeder 220 for feeding yarn is provided on the conveying conveyor 210 and a hopper 230 is installed below the feeder 220. The hopper 230 guides the yarn fed from the feeder 220 down smoothly.

Inside the hopper 230, a pair of multi-row rotary brushes 240 are arranged side by side. The multirow rotary brush 240 is rotated by the driving source. The yarn is trapped in the same (uniform) amount between the plurality of brushes provided on the outer periphery of the rotating multi-row rotary brush 240, and falls down through the outlet at the lower portion of the hopper 230.

In the present invention, by arranging the two multirow brushes 240 side by side, the phenomenon that the yarn is biased to one side is prevented, and uniform distribution is enabled. It is natural that the quality of the carpet is increased by uniformly distributing the yarn.

In addition, a plurality of beater bars 250 are disposed at a predetermined interval below the conveying conveyor 210 in the form of a net.

The bitter bar 250 has a plurality of protrusions on its outer periphery and rotates at a lower portion of the conveying conveyor 210. Each time the protrusion of the rotating bitter bar 250 passes, the mesh conveyor 210 is struck up and the impact is applied to fasten the yarn to the adhesive layer quickly and firmly.

The raw yarn that does not come into contact with the substrate 1 or falls to the periphery passes through the conveying conveyor 210 in the form of a net and collects in the lower collecting tank 260 and is sucked and reused by a predetermined suction device.

As described above, the electrophoretic deposition stage 200 according to the present invention can uniformly distribute the yarn by the pair of multirow brushes 240, promote the formation of the yarn by the bitter bar 250, This makes it possible to obtain a carpet having uniform yarn densities and to shorten the feeding time of the yarn and freely adjust the yarn in accordance with other processes, thereby facilitating the sequencing of the process.

4, the drying stage 300 is disposed adjacent to the electroforming stage 200 and receives and transports a fabric (substrate + yarn) 2 coming from the electrophoretic casting mold stage 200, The adhesive layer is dried and hardened to securely adhere the yarn.

The drying stage 300 includes a drying chamber 310 through which the fabric 2 passes and a hot air nozzle 311 for spraying hot air to the drying chamber 310. The fabric 2 coming from the electrophoretic deposition stage 200 is dried by the hot air blowing from the hot air nozzle 311 while passing inside the drying chamber 310 by the conveyor.

As shown in Fig. 5, the forced cooling stage 400 can be formed by forcibly cooling the raw material 2 by the coolant without using the conventional cooling method by natural leaving, thereby increasing the cooling effect and shortening the cooling time .

In an embodiment of the present invention, the fabric 2 is forcedly cooled by the refrigerant while continuously passing through the cooling unit 420. This allows the cooling process to be easily combined with other processes in a sequencing process. A connection stage 410 for smoothly transferring the raw fabric 2 to the cooling unit 420 may be provided upstream of the cooling stage 440.

The forced cooling stage 400 includes the cooling unit 420 described above. The towing and guiding devices 400 and 450 may be juxtaposed for guiding and guiding the fabric 2 from the cooling unit 420 in a cushioning manner.

The cooling unit 420 includes a refrigerant drum 430 arranged in a zigzag manner on the frame 421. [ A coolant such as cooling water circulates inside the coolant drum 430. The connection of the refrigerant circulation device and the refrigerant drum 430 is connected by a known rotary connection port.

The plurality of coolant drums 430 can be rotated by a single drive source. Each of the refrigerant drums 430 is provided with a pulley 431 and the driving source 432 and the pulleys 431 are connected to each other by a belt 433. [ An idler pulley 434 may be interposed for connecting the belt 433. [

The fabric 2 is aligned such that the outer peripheries of these coolant drums 430 are alternately passed by way. Thus, the fabric 2 is rapidly and easily cooled while sequentially contacting the refrigerant drums 430. In addition, the cooling effect is maximized by the zigzag arrangement of the coolant drum 430 and the staggered connection of the fabric 2 to contact the inner surface and the outer surface of the fabric 2 in turn with the coolant drum 430.

According to the constitution in which the fabric 2 is forcedly cooled by the cooling drum 430 and the refrigerant drum 430 is continuously aligned, the cooling time can be significantly shortened as compared with the conventional cooling method by natural leaving It is possible to combine the processes with the neighboring processes and the sequencing process.

Next, as shown in FIG. 6, the winding stage 500 has a branch tube 510 around which the fabric 2 is wound. A plurality of guide rollers 520 may be installed in combination to easily guide the fabric 2 to the paper tube 510.
