A support having a progress section that bends upward on the normal trajectory and proceeds along the upper trajectory in an inverted state while being guided by the support, and then bends downward again and returns to the normal trajectory, and proceeds in an inverted state on the upper trajectory of the support. It consists of an adsorbent removal unit installed in the section to remove the adsorbent that is not adhered to the support, and an adsorbent recovery fan installed below the adsorbent removal unit to collect the adsorbent that falls downward as it is removed by the adsorbent removal unit. It is a characteristic.

Here, the adsorbent removal unit may be comprised of an air blower that sprays air toward the support and blows out the non-adherent adsorbent using the pressure of the air, or a recovery part vibrator that applies vibration to the support and shakes off the non-adherent adsorbent with vibration force.

It may further include a chamber installed as a.

At this time, the section that progresses in an inverted state in the upper trajectory of the support overlaps above the section that proceeds along the normal trajectory of the support before the upper trajectory, so that the adsorbent falling downward by the adsorbent removal unit moves before the upper trajectory. (Previously) Can be re-adhered onto the support.

The non-adherent adsorbent recovery device of this filter manufacturing facility may further include a pressure roller installed at the front end of the adsorbent removal unit to press the adsorbent applied on the support before removing the non-adherent adsorbent to the adsorbent removal unit. , It may further include a suction pipe that extends to the inside of the adsorbent recovery fan and recovers the adsorbent collected in the adsorbent recovery fan by suction.

In a preferred embodiment, the adsorbent adhesion device of the filter manufacturing facility is disposed at the front and rear ends of the line, respectively, and includes a primary unwinder and a primary rewinder for supply, recovery, and transfer of the primary support, and the primary The primary hot melt spray and primary scatter parts are placed on top of the primary support that progresses along the forward working flow between the unwinder and the primary rewinder and apply the hot melt and adsorbent respectively, and are placed at the upper end of the line. A secondary unwinder for supplying the secondary support is placed at the upper part of the reverse working flow section of the secondary support, which proceeds along the reverse working flow and the forward working flow between the secondary unwinder and the first rewinder. secondary hot melt spray and secondary scatter parts that apply hot melt and adsorbent, respectively, and upper and lower secondary supports and primary parts disposed in the forward working flow section of the primary and secondary supports and onto which hot melt and adsorbent are applied.

Hereinafter, the present invention will be described in detail with reference to the attached drawings.

Figure 1 is a front view showing a scatter part and an adsorbent recovery part in a non-bonded adsorbent recovery device of a filter manufacturing facility according to an embodiment of the present invention, and Figure 2 is a front view showing a non-bonded adsorbent recovery device of a filter manufacturing facility according to an embodiment of the present invention. It is an enlarged view showing the scatter part in the adsorbent recovery device, and FIGS. 3A and 3B are enlarged views showing the adsorbent recovery part in the non-adherent adsorbent recovery device of the filter manufacturing facility according to an embodiment of the present invention.

As shown in FIGS. 1 and 2, 3A and 3B, the adsorbent adhesion device of the filter manufacturing equipment fails to adhere to the hot melt among the adsorbents applied to the support and forces the unadhered adsorbent floating on it with air or vibration. In addition to shaking off, the adsorbent that falls down at this time is made to adhere to the support again, and the adsorbent that is pushed to the side on the support and falls down from the edge in the width direction is collected in a fan and recovered.

For this purpose, the adsorbent adhesion device of the filter manufacturing facility includes a scatterer part 10 as a means for applying the adsorbent onto the support on which the hot melt is applied.

The scatter part 10 includes an adsorbent reservoir 28 having an upper inlet 26 and a lower outlet 27 for storing a certain amount of adsorbent, and a plurality of grooves 29 on the outer peripheral surface of the adsorbent reservoir. An adsorbent transport roller 30 and a roller drive motor 31 that are installed in a rotatable structure at the bottom of the outlet 27 at (28) to transport the adsorbent filled in the adsorbent reservoir 28 downward, and the adsorbent It receives the adsorbent transferred from the transfer roller 30 and drops it on the support below, and includes a vibrator 32 equipped with a mesh net (not shown).

Here, a portion of the outer circumferential surface of the adsorbent transport roller 30 is in contact with the outlet 27 of the adsorbent reservoir 28, and accordingly, the adsorbent filled inside the adsorbent reservoir 28 is on the outer circumferential surface of the adsorbent transport roller 30. As it piles up, it enters the groove (29), and eventually only the adsorbents inserted into the groove (29) of the adsorbent transport roller (30) can exit the adsorbent reservoir (28).

And, the vibrator 32 of the scatter part 10 is supported on the side of the vibrator driving motor 33 and driven according to the operation of the vibrator driving motor 33.

For example, a vibrator driving motor 33 is vertically installed on the part frame 34 of the scatter part 10, and a rod 36 is installed on the axis of the vibrator driving motor 33. , At the lower end of the rod 36 installed in this way, a cam follower 43 (CF10UUR) is installed that is eccentric with the center of the rod.

In addition, a block 37 having a cam follower groove 42 is disposed at the bottom of the rod 36, and the cam follower 43 is inserted into the cam follower groove 42 of the block 37. .

Accordingly, when the rod 36 rotates, the cam follower 43 rotates eccentrically, and as a result, the block 37 sliding with the cam follower 43 reciprocates in the left and right directions.

At this time, a vibrator 32 is installed on the block 37 through a bracket 38.

In addition, the entire bracket 38 including the vibrator 32 can move back and forth in the left and right directions (for example, in a direction at 90° with respect to the direction in which the support moves) while being guided by the LM guide 41.

Therefore, by the operation of the vibrator driving motor 33, the vibrator 32 moves back and forth left and right by interlocking between the cam follower 43 and the block 37 (that is, the rotational motion is converted to a reciprocating motion). It vibrates, and eventually the adsorbent supplied thereon falls downward through the mesh network of the vibrator 32 due to this vibration.

If the vibrator 32 is installed on the scatter part 10 in this way, the uniformity of the adsorbent scatterer improves.

This scatter part 10 is installed on one side of the adsorbent transport roller 30 and includes an adsorbent brush 35 that drops the adsorbent inserted into the groove 29 of the adsorbent transport roller 30.

At this time, the adsorbent brush 35 can be installed in a structure supported on the bracket 38 that supports the vibrator 32.

In addition, a scrap bar 39 is installed on one side of the lower end of the adsorbent storage tank 28, that is, on one side of the outlet 27, and the end of the scrap bar 39 installed in this way is connected to the adsorbent transport roller 30. It comes into contact with the outer circumferential surface, and eventually the adsorbent that cannot enter the groove (29) and accumulates around the outer circumferential surface of the adsorbent transport roller (30) is filtered by the scrap bar (39) and cannot escape.

In addition, the scrap bar 39 can move its position in the forward and backward directions (e.g., closer to the adsorbent transport roller side or away from the adsorbent transport roller side) and/or in the up and down direction, and thus depending on the type and size of the adsorbent. The gap between the scrap bar 39 and the adsorbent transfer roller 30 can be adjusted.

Therefore, in a state where the adsorbent reservoir 28 is filled with adsorbent, when the adsorbent transport roller 30 is rotated by the operation of the roller drive motor 31, the adsorbent moves into each groove 29 of the adsorbent transport roller 30. The adsorbent contained in the groove (29) of the adsorbent transfer roller (30) is then transferred while being inserted into the adsorbent brush (35) and falls on the vibrator (32) below as it is interfered with by the adsorbent brush (35). ) The adsorbent falls downward due to the vibration of the vibrator 32 and can be applied on the support.

In addition, the non-adherent adsorbent recovery device of the filter manufacturing facility includes a pressure roller 22 as a means to press and adhere the adsorbent onto the hot melt applied to the surface of the support 100.

The pressure roller 22 is installed at the front end of the adsorbent recovery part 11 (e.g., the rear end of the scatter part) and is placed on the support 100 before removing the unadhered adsorbent with the adsorbent recovery part 11. It plays the role of holding down the applied adsorbent.

For this purpose, a roller bracket 25 is installed on one wall of the part frame 34, and a roller cylinder 40 is installed in a vertical position on the upper plate of the roller bracket 25, and the roller cylinder installed in this way ( A pressure roller 22 is installed on the rod of 40) in a rotatable structure.

At this time, the pressure roller 22 has a length corresponding to the width of the support 100 and is disposed across the width direction of the support 100.

In addition, bearing rollers 24 for guiding and supporting the transport of the support 100 are arranged side by side below the pressure roller 22, and accordingly, the pressure roller 22 is positioned between the bearing rollers 24 and the bearing roller 24. It is possible to press the adsorbent on the support 100 passing through, and as a result, most of the adsorbent is firmly fixed on the support 100, making it possible to minimize the amount of unadhered adsorbent.

In addition, the non-adherent adsorbent recovery device of the filter manufacturing facility includes an adsorbent recovery part (11) as a means of forcibly removing the adsorbent that has not adhered to the hot melt applied to the surface of the support and then applying and recovering it again on the support. do.

The adsorbent recovery part 11 includes a support 100 that is transported along a predetermined curved trajectory, an adsorbent removal unit 13 that removes unadhered adsorbent from the support to which hot melt and adsorbent are applied, and re-adhesion on the support. It consists of an adsorbent recovery fan (14) that recovers the unused adsorbent.

The support 100 includes a plurality of guide rollers 12, for example, two guide rollers 12 respectively disposed on the entry and exit sides in contact with the normal trajectory, and arranged in an approximately square trajectory above the normal trajectory. It proceeds along a predetermined trajectory while being guided by a total of six guide rollers (12), including four guide rollers (12).

This support 100 is then bent upward from its normal trajectory (eg, a straight horizontal section between the unwinder and the rewinder). It proceeds along the upper trajectory in an inverted and upright state, then bends downward again and is transported along a progress section that returns to the normal trajectory.

At this time, the section in which the support 100 progresses in an inverted state in the upper trajectory is overlapped and placed immediately above the section in which the support 100 proceeds along the normal trajectory before entering the upper trajectory.

Accordingly, the non-adhered adsorbent removed from the support 100 moving along the upper trajectory by the adsorbent removal unit 13 can fall and adhere to the support 100 before the upper trajectory.

The adsorbent removal unit 13 serves to remove the non-adhered adsorbent on the support 100 from the support 100 using air pressure or vibration.

This adsorbent removal unit 13 is installed in a section that proceeds in an inverted state (e.g., with the adsorbent facing downward) among the entire section of the upper trajectory of the support 100 and is not adhered to the support 100. The adsorbent can be removed.

Here, the adsorbent removal unit 13 is an air blower 13a that sprays high-pressure air on the support 100 side to blow out and remove the non-adherent adsorbent with the pressure of the air, and is in contact with the support 100 side to generate vibration. This can be done with a recovery part vibrator (13b) that shakes off and removes the non-adhered adsorbent using the vibration force at this time.

Accordingly, when the air pressure of the air blower 13a or the vibration of the recovery part vibrator 13b is applied to the support 100, the non-adhesive adsorbent on the support 100 turned upside down falls from the support 100. It comes out and falls down, and the adsorbent that falls in this way can be re-applied and adhered to the support 100 passing below. At this time, it is not able to adhere to the support 100 and is pushed to both sides of the width of the support 100. The unadhered adsorbent that falls off can be collected in the adsorbent recovery pan (14).

In addition, a chamber 47 is installed around the adsorbent removal unit 13 to create a predetermined internal space, thereby preventing the non-adherent adsorbents removed from the support 100 from scattering in all directions.

This chamber 47 has a support inlet 44 on one side through which the support 100 enters, a support outlet 45 on the other side through which the support 100 exits, and a lower adsorbent outlet 46 through which the adsorbent exits downward. It is installed in a structure surrounding the periphery of the adsorbent removal unit 13.

Here, the chamber 47 can be installed in a structure supported on a device frame (not shown) on which guide rollers 12 are installed.

Accordingly, the non-adhered adsorbents that come off the support 100 due to the air pressure of the air blower 13a or the vibration of the recovery part vibrator 13b are trapped inside the chamber 47 and are not scattered in all directions, but are stored below. It can fall downward through the adsorbent outlet (46).

The adsorbent recovery pan 14 serves to collect the non-adherent adsorbents that are not re-adhered to the support 100 and are pushed to the side and fall out of the non-adhered adsorbents that are removed by the adsorbent removal unit 13 and fall downward. .

This adsorbent recovery fan 14 is installed below the adsorbent removal unit 13, that is, below the section that proceeds along the normal trajectory of the support 100 before entering the upper trajectory, and this adsorbent recovery fan ( 14) can receive and collect the non-adherent adsorbent (unrecycled non-adhesive adsorbent) that cannot be re-adhered to the support 100 and falls on both sides of the width of the support.

In a preferred embodiment, the adsorbent recovery fan 14 includes a suction pipe 23, where the suction pipe 23 is a means for forcibly recovering the unadhered adsorbent that has fallen off the support, and is operated by a vacuum motor (not shown). ), etc., is extended to the inside of the adsorbent recovery fan 14, and the suction pipe 23 installed in this way can suction and recover the adsorbent gathered in the adsorbent recovery fan 14.

Accordingly, the support 100, which was transported along a normal trajectory after application of the hot melt and adsorbent, is bent upward from the position of the first guide roller 12 of the adsorbent recovery part 11, and at the same time, the microstructure on the support 100 is moved. The adhesive adsorbent is separated from the support 100 by the adsorbent removal unit 13, and the non-adhesive adsorbent that has come off is re-attached to the support 100 passing below, and the non-adherent adsorbent that has not been attached at this time is released into the adsorbent recovery fan. The adsorbent collected in (14) continues to be collected in the adsorbent recovery pan (14) and can be recovered and reused through the suction pipe (23).

Figures 4a to 4c are schematic diagrams showing the overall working flow of the filter manufacturing equipment to which the non-adherent adsorbent recovery device according to an embodiment of the present invention belongs.

As shown in FIGS. 4A to 4C, the filter manufacturing equipment advances the primary support and the secondary support to which the hot melt and the adsorbent are applied, respectively, along their respective working flows, for example, the primary support moves in the forward direction. In addition to proceeding along the flow, the secondary support includes a complex laminating process to manufacture a filter in the form of a second support being laminated on top of the primary support while proceeding along a reverse working flow and a forward working flow.

To this end, the filter manufacturing equipment includes a primary unwinder 15 and a primary rewinder 16 as means for supplying, recovering, and transporting the primary support 100a.

The first unwinder 15 and the first rewinder 16 are disposed at the front end and the rear end of the line (e.g., a process line for filter manufacturing), respectively, and the first unwinder 15 disposed in this way The primary support (100a) is caught between the primary rewinders (16).

Accordingly, when the primary unwinder 15 and/or the primary rewinder 16 is driven, the primary support 100a is unwound from the primary unwinder 15 and moves to the rear end along the forward working flow. It progresses toward and is wound around the primary rewinder (16).

Here, the primary support 100a may be made of a breathable material such as non-woven fabric (e.g., LM (low melting PET non-woven fabric), LM + electrostatic MB).

In addition, the filter manufacturing equipment includes a primary hot melt spray 17 and a primary scatter part 10a as means for applying the hot melt 200 and the adsorbent 400, respectively, on the primary support 100a.

The first hot melt spray 17 and the first scatter part 10a are located on the upper part of the first support 100a, which proceeds along a forward working flow between the first unwinder 15 and the first rewinder 16. are placed in order, and the first hot melt spray 17 and the first scatter part 10a sequentially apply the hot melt and adsorbent to the upper surface of the first support 100a.

That is, the hot melt in a molten state is first applied by the first hot melt spray 17, and then an adsorbent (e.g., activated carbon, etc.) is applied on top of it by the first scatter part 10a. Accordingly, the adsorbent is used as a hot melt. It is attached to the upper surface of the primary support 100a.

In addition, the filter manufacturing equipment includes a secondary unwinder 18 as a means of supplying a secondary support 100b that is laminated and coupled to the primary support 100a.

The secondary unwinder 18 is disposed at the upper part of the rear end of the line, for example, above the primary rewinder 16 installed at the rear end of the line, and the secondary unwinder 18 arranged in this way The secondary support body 100b is caught between the primary rewinders 16.

In addition, the secondary support 100b proceeds along a reverse working flow while following a predetermined trajectory by a plurality of idlers, and then proceeds along a forward working flow together with the primary support 100a to the primary rewinder 16. It gets cold.

Here, the secondary support 100b can also be made of a breathable material such as non-woven fabric (eg, LM, LM+MB).

By adopting the method of placing the secondary support 100b above the rear end of the line and proceeding along the reverse working flow and forward working flow, space utilization related to the linked arrangement of devices such as hot melt spray, scatter parts, etc. There is an advantage in that the factory layout can be designed efficiently.

In addition, the filter manufacturing equipment includes a secondary hot melt spray 19 and a secondary scatter part 10b as means for applying hot melt and adsorbent on the secondary support 100b, respectively.

The secondary hot melt spray (19) and secondary scatter part (10b) are secondary supports ( The secondary hot melt spray 19 and the secondary scatter part 10b are arranged sequentially at the upper part of 100b), for example, at the upper part of the section running along the reverse working flow of the secondary support 100b. The hot melt and the adsorbent are sequentially applied to the bottom of the secondary support 100b (e.g., the side facing downward when laminated on the primary support).

That is, the hot melt in a molten state is first applied by the secondary hot melt spray 19, and then an adsorbent (e.g., activated carbon, etc.) is applied thereon by the secondary scatter part 10b. Accordingly, the adsorbent is applied to the hot melt. It is attached to the bottom of the secondary support 100b.

In addition, the filter manufacturing equipment includes a press roller 20 as a means for pressing and fixing the secondary support 100b and the primary support 100a stacked up and down.

The press rollers 20 may be composed of a pair positioned above and below the path of the support, and the press rollers 20 move in a state in which the primary support 100a and the secondary support 100b are combined. It is placed in the forward working flow section to compress the upper and lower secondary supports 100b and primary supports 100a to which hot melt and adsorbent are applied.

Here, it is preferable that at least one press roller 20 among the pair of press rollers 20 is a roller with a built-in heater (not shown).

In addition, the filter manufacturing equipment includes a tertiary unwinder 21 as a means of supplying the protective nonwoven fabric 300 attached to the upper surface of the secondary support 100b.

The 3rd unwinder 21 is placed at the upper part of the rear end of the line and serves to supply the protective nonwoven fabric 300. At this time, there is a gap between the 3rd unwinder 21 and the 1st rewinder 16. The protective nonwoven fabric 300 is caught.

In addition, the protective nonwoven fabric 300 supplied from the tertiary winder 21 can be adhered to the upper surface of the secondary support 100b while proceeding along the reverse working flow and the forward working flow.

At this time, the path of the forward walking flow of the protective nonwoven fabric 300 is the point where the path of the forward walking flow of the secondary support 100b begins (e.g., the point where the primary support and the secondary support are combined) and the press roller ( It can be started at any point in the section between the points where 20) is located.

Accordingly, the laminating work process for manufacturing a filter in a filter manufacturing facility including the non-adherent adsorbent recovery device is as follows.

After the first support (100a) is hung on the first unwinder (15), the second support (100b) is also hung on the second unwinder (18), and the first support (100a) and the second support are hung in this way. Extend (100b) to the primary rewinder (16) and hang it.

In this state, when the first rewinder 16 is operated, the first support 100a and the second support 100b are released from the first unwinder 15 and the second unwinder 18, respectively. and is wound on the primary rewinder (16) side.

At the same time, the hot melt sprayed from the first hot melt spray 17 and the adsorbent dropped from the first scatter part 10a are sequentially applied on the first support 100a, and in parallel, 2 on the second support 100b. The hot melt sprayed from the primary hot melt spray (19) and the adsorbent dropped from the secondary scatter part (10b) are applied sequentially.

Subsequently, the adsorbent applied on the primary support 100a passes through the pressure roller 22, and at this time, the adsorbent is pressed by the pressure roller 22 and mostly adheres to the hot melt on the primary support 100a. It becomes possible.

In particular, after the hot melt and adsorbent are applied and pressurized on the primary support (100a), the adsorbent on the continuously advancing primary support (100a) bends upward from the normal trajectory, then proceeds along the upper trajectory, and then moves downward again. After being bent, in the process of returning to the normal trajectory, it is subjected to air pressure and/or vibration of the vibrator, and the primary support 100a, which continues to be turned over, i.e. the side on which the adsorbent is applied, faces downward. The non-adhered adsorbent on the primary support 100a, which is in a state, falls off the primary support 100a due to air pressure or vibration of the vibrator, falls on the primary support 100a passing underneath, and is re-adhered, continuing. Therefore, the non-adhered adsorbent that falls off from both sides of the width of the primary support (100a) is collected in the adsorbent recovery pan (14).

Subsequently, the secondary support 100b and the primary support 100a, each coated with hot melt and adsorbent, are stacked up and down and pass through the press roller 20, and are then pressed by the press roller 20. The filter (composite filter medium) with a single-layer structure, which is made integrally by being pressed in a laminated state, is recovered in the primary rewinder (16).

Figure 5 is a cross-sectional view showing single-layer and multi-layer filters manufactured using filter manufacturing equipment including a non-adherent adsorbent recovery device according to an embodiment of the present invention.

As shown in Figure 5, the (A) type filter and (B) type filter are single-layer composite filters that can simultaneously implement both dust collection and deodorization functions, and are used in automobile air conditioner combination filters, air purifier filters, etc. do.

These filters are a combination of LM non-woven fabric (secondary support) + hot melt + adsorbent + hot melt + LM non-woven fabric (primary support), which are layered sequentially from top to bottom, or MB non-woven fabric (protective non-woven fabric) + LM non-woven fabric (secondary support). It is composed of a combination of +hot melt + adsorbent + hot melt + LM nonwoven fabric (primary support).

In addition, the (C) type filter is a chemical filter for HF removal with a multi-layer structure required for clean rooms, and is made up of multiple layers of hot melt and adsorbent repeatedly layered between the upper and lower LM nonwoven fabrics.

Here, the (B) type is capable of both dust collection and deodorization functions, and reference numeral 300 is an MB filter non-woven fabric that functions as a dust collection filter.

Type (A) is a single-layer adsorbent type, and type (C) is a multi-layer type.

Additionally, there is a limit to the amount of adsorbent that can be attached to one layer, so the amount of adsorbent can be increased by raising many layers. In particular, different types of adsorbent can be used to increase the amount of adsorbent, which is advantageous for responding to complex gases.

Type (C) can also function as a dust collection filter by attaching the MB filter non-woven fabric on top.

In this way, in the present invention, the adsorbent that is not adhered to the support is shaken downward with air or a vibrator while guiding upward along the trajectory of the support on which the hot melt and the adsorbent are applied, and the adsorbent that falls in this way is transferred to the support moving from the back. By providing a new non-adhesive adsorbent recovery device with an adsorbent recovery part that not only allows the adsorbent to be re-applied on the support but also recovers the adsorbent that falls off to the side, it is possible to maintain a stable adsorbent application state on the support and improve product yield. At the same time, the quality of the product can be secured, and the non-adhesive adsorbent can be recovered and reused, which is advantageous in terms of economic efficiency.

In addition, in the present invention, a first laminating process is performed while proceeding along a forward working flow at the lower part, and in parallel, a secondary laminating process is performed along a reverse working flow and forward working flow at the upper part. By providing a laminating process, the efficiency of the process can be increased, such as by optimally designing the layout of the laminating process, and the space utilization of the factory can be improved as well as productivity.
