It is related with the nonwoven fabric winding apparatus for filter molded bodies, and the nonwoven fabric winding method for filter molded bodies.

  Conventionally, as a filter attached to a water treatment device for removing contaminants such as chlorine and dust from water, there is a filter provided with a filter body formed as a cylindrical filter formed by solidifying activated carbon. It is used. In this filter, water passes through the filter body from the outer peripheral side of the cylindrical shape to the inside, and at that time, chlorine, small dust, and the like are removed by the adsorption function of the activated carbon. As such a filter, a filter in which a nonwoven fabric is wound around and fixed to the outer periphery of the filter body is known (see, for example, Patent Document 1 and Patent Document 2). In the filters disclosed in Patent Document 1 and Patent Document 2, when water passes from the outer peripheral side to the inside of the filter body, relatively large dust is first removed by the nonwoven fabric wound and fixed around the outer periphery.

A hole is formed at the center of one cap 104a, and the cap 104a is attached to the filter body 102 so that the hole and the through hole 102a of the filter body 102 communicate with each other.

  The filter 100 configured as described above is attached to, for example, the water treatment device 101 shown in FIG. The water treatment device 101 includes, for example, a water purifier main body 106 attached to a faucet 105 for home water supply. And the filter 100 is fixed inside the water purifier main body 106 formed hollow. The filter 100 is disposed so that the cap 104a faces downward, and is fixed in a state where the through hole 102a communicates with a water purification port 108 formed to open downward from the water purifier main body 106.

A switching plate 107 is provided. By this switching plate 107, the flow path of the water supplied from the faucet 105 is between the flow path that flows out without passing through the filter 100 and the flow path that flows out through the filter 100 as shown in FIG. 3. Switch with.

  In a state where the switching plate 107 is switched to the position shown in FIG. 3, the water supplied from the faucet 105 flows as indicated by the dashed arrow in the figure. That is, the water from the faucet 105 reaches the outer periphery of the filter 100 through the flow path inside the water purifier main body 106, passes through the nonwoven fabric 103, further passes through the filter main body 102, and flows to the inside thereof. And it flows through the water purification port 108 from the through-hole 102a, and water flows out outside. As the water passes through the filter 100 in this way, contaminants such as chlorine and dust are removed from the water. In addition, the water treated by the filter 100 first removes relatively large dust by passing through the nonwoven fabric 103, and then passes through the filter main body 102 so that chlorine, small dust, and the like are caused by the adsorption action of the activated carbon. Will be removed.

  In addition, the filter 100 is not restricted to what is directly attached to a faucet like the water purifier 101 mentioned above, It can attach and use with respect to the water purifier of various forms. For example, the filter 100 may be installed in a water purifier that is disposed in a sink and connected to a faucet and a hose, and in the water purifier that is also configured as a shower handle, You may attach in the state accommodated in the container.

  Next, the nonwoven fabric winding method for filter molded bodies according to the first embodiment of the present invention (hereinafter also simply referred to as “winding method”) will be described. In addition, the winding method of this embodiment will be implemented by operating the nonwoven fabric winding apparatus 1 for filter molded bodies mentioned above.

  The winding method of this embodiment is used when manufacturing the filter 100, and is configured as a winding method for winding and fixing the nonwoven fabric 103 around the outer periphery of the filter body 102. In the manufacture of the filter 100, as a pre-process of the winding method of the present embodiment, a filter body 102 forming step (filter forming body forming step) is performed. Moreover, the cap attachment process which attaches a cap (104a, 104b) to the both ends of the filter main body 102 around which the nonwoven fabric 103 was wound and fixed is performed as a post process of the winding method of this embodiment.

FIG. 11 is a process diagram illustrating the winding method of the present embodiment. As shown in FIG. 11, the winding method of the present embodiment includes a nonwoven fabric placing step S101, a start-time heat welding step S102, a rotational movement step S103, and an end-time heat welding step S104. Has been. By performing these steps (S101 to S104) in order, the work of winding and fixing the nonwoven fabric 103 around the filter body 102 is performed. And whenever each process (S101-S104) is complete | finished once, the nonwoven fabric 103 is wound and the filter 102 fixed by winding will be manufactured, and each process (S101-S104) will be performed repeatedly. Thus, the filter 102 around which the nonwoven fabric 103 is wound and fixed is repeatedly manufactured.

  The nonwoven fabric placement step S101 is configured as a step of placing the nonwoven fabric 103 on the nonwoven fabric placement surface 11a in the base 11 having the nonwoven fabric placement surface 11a. That is, in this nonwoven fabric placement step S101, as shown well in FIG. 7, the rectangular nonwoven fabric 103 is placed in a state where the nonwoven fabric placement surface 11a between the pair of guide portions 12 is spread. Become. At this time, the nonwoven fabric 103 is placed so that each of the four sides is arranged along the corresponding first to third heaters (13 to 15). In addition, before this nonwoven fabric mounting process S101 is performed, or before the nonwoven fabric mounting process S101 is performed and the start time heat welding process S102 is performed, the power supply of the winding apparatus 1 is turned on. The first to third heaters (13 to 15) are energized by the controller 17 based on an operation by the operator so that the temperature of the first to third heaters (13 to 15) becomes a predetermined target temperature. The current will be adjusted.

  In the start-time heat welding step S102, the filter main body 102 is disposed from the end of the nonwoven fabric 103 on the first heater 13 disposed at the rotational movement start position, and is placed on the nonwoven fabric placement surface 11a. This is configured as a process in which the nonwoven fabric 103 and the filter body 102 are heated and thermally welded. In the start-time heat welding step S102, the operator causes a part of the outer periphery along the axial direction of the filter main body 102 to contact the stopper 16 on the nonwoven fabric placement surface 11a between the pair of guide portions 12. The filter body 102 is disposed on the surface. As a result, the filter main body 102 is disposed at the rotational movement start position and is positioned on the first heater 13. Then, the operator presses the filter main body 102 from above and urges the filter main body 102 toward the first heater 13 through the end of the nonwoven fabric 103, so that the heat transmitted from the first heater 13 The end of the nonwoven fabric 103 and a part of the outer periphery along the axial direction of the filter body 102 are heated and thermally welded. At this time, in the filter body 102, the polyester having a low melting point is melted without melting the polyester, so that the filter body 102 and the end portion of the nonwoven fabric 103 are thermally welded.

  In the rotational movement process S103, between the pair of guide portions 12, each of both end portions of the filter main body 102 arranged on the nonwoven fabric placement surface 11a is made into parallel opposing surfaces (21a, 21b) in the pair of guide portions 12. The filter main body 102 is configured to rotate and move while being in sliding contact with the filter body 102. In this rotational movement step S102, the operator rotates the filter body 102 in the rotational movement direction indicated by the arrow C in FIG. Move to rotate. Thereby, the nonwoven fabric 103 is wound around the outer periphery of the filter body 102 as the filter body 102 rotates. In addition, during this rotational movement step S103, the nonwoven fabric 103 is wound around the outer periphery of the filter body 102, and the outer periphery of both ends of the nonwoven fabric 103 and the filter body 102 by the pair of third heaters 15 (15a, 15b). Are heated and welded. In FIG. 8, the position of the filter main body 102 in the middle of the rotational movement and the position of the filter main body 102 disposed on the second heater 14 after the winding of the nonwoven fabric 103 by the rotational movement is finished are shown in the figure. This is indicated by a two-dot chain line.

In the end heat welding step S104, both ends of the nonwoven fabric 103 are heated with respect to the filter main body 102 in a state where the ends of the nonwoven fabric 103 wound around the outer periphery of the main body filter 102 are overlapped on the second heater 14. It is comprised as a process of heat-welding. When the operator rotates the filter body 102 over the second heater 14 while winding the nonwoven fabric 103 around the outer periphery thereof, the rotation movement of the filter body 102 is stopped on the second heater 14. Then, in this end heat welding step S104, the operator presses the filter main body 102 from above, and biases the filter main body 102 toward the second heater 14 through the end of the overlapped nonwoven fabric 103. The heat transferred from the second heater 14 heats the ends of the nonwoven fabric 103 and a part of the outer periphery along the axial direction of the filter main body 102 to be heat-welded. At this time, as described above, in the filter main body 102, only polyethylene is melted, and the end portions of the filter main body 102 and the nonwoven fabric 103 are thermally welded. Since the polyester remains in a fibrous state without melting, the water permeability in the heat-sealed portion is sufficiently ensured in a state where the heat-sealing is finished and fixed.

  When the end heat welding step S104 is completed, the operator rotates the filter body 102 around which the nonwoven fabric 103 is wound and fixed, and passes over the second heater 14 so as to pass between the pair of guide portions 12. Let it escape. And the filter main body 102 with which the nonwoven fabric 103 was wound and fixed was taken out from the base 11, and the winding method of this embodiment is complete | finished. Further, when the nonwoven fabric 103 is wound and fixed on the new filter body 102, the above steps (S101 to S104) are repeated.

  According to the winding device 1 described above, when performing the work of winding and fixing the nonwoven fabric 103 around the outer periphery of the filter body 102, which is a cylindrical filter molded body formed by solidifying activated carbon, The nonwoven fabric 103 is placed on the nonwoven fabric placement surface 11 a of the base 11, and the filter body 102 is placed and pressed from above the nonwoven fabric 103 on the first heater 13 provided at the rotational movement start position. Thereby, the nonwoven fabric 103 and the filter main body 102 are heat-welded. Then, by rotating the filter body 102 on the nonwoven fabric placement surface 11 a between the pair of guide portions 12, both ends of the filter body 102 are in sliding contact with the opposing surfaces (21 a, 21 b) of the pair of guide portions 12. The rotational movement direction of the filter body 102 is guided in a predetermined direction, and the nonwoven fabric 103 is wound around the outer periphery of the filter body 102 in a state where the filter body 102 is pulled appropriately without generating wrinkles. For this reason, the work of winding the nonwoven fabric 103 around the outer periphery of the filter body 102 in a state in which the nonwoven fabric 103 is appropriately pulled without causing wrinkles, regardless of the difference between workers and the situation of the worker, By simply rotating and moving 102, the process can be performed very easily and quickly. Then, the operator presses the filter main body 102 toward the second heater 14 in a state where the filter main body 102 is rotationally moved above the second heater 14, and thereby the nonwoven fabric wound around the outer periphery of the filter main body 102. It is possible to perform heat welding to the filter main body 102 in a state where the end portions of 103 are overlapped. Thereby, the operation | work which winds and fixes the nonwoven fabric 103 around the outer periphery of the filter main body 102 is complete | finished. Therefore, since the nonwoven fabric 103 is easily wound and fixed around the outer periphery of the filter body 102 in a state of being pulled as appropriate without causing wrinkles, regardless of the difference in worker and the situation of the worker, the appearance quality varies. Is suppressed, and the appearance quality is improved. Then, after placing the nonwoven fabric 103 on the base 11, the filter body 102 is rotationally moved between the pair of guide portions 12 and pressed against the heaters (13, 14) at the start and end of the rotational movement. Therefore, the work time can be greatly shortened regardless of the difference in worker and the situation of the worker. As a result, variations in work efficiency are suppressed, and work efficiency is improved.

Therefore, according to the nonwoven fabric wrapping apparatus 1 for a filter molded body, it is possible to suppress the appearance quality variation and the work efficiency variation from occurring due to the difference in the worker or depending on the situation of the worker, thereby improving the appearance quality and the work efficiency. Can be planned.

  In addition, according to the winding device 1, the first heater 13 that thermally welds the nonwoven fabric 103 to the filter body 102 at the start of the rotational movement is arranged extending in a direction orthogonal to the rotational movement direction, so that the rectangular heater The nonwoven fabric 103 can be easily wound around the outer periphery of the filter body 102 while pulling without generating wrinkles. For this reason, the edge part of the nonwoven fabric 103 heat-welded with respect to the filter main body 102 is arrange | positioned in parallel with the axial direction of the filter main body 102, without arrange | positioning spirally. As a result, the tensile force acting on the nonwoven fabric 103 in the outer circumferential direction of the filter body 102 can be made more uniform in the direction parallel to the axial direction of the filter body 102, and the appearance quality can be further improved. Can do.

  Further, according to the winding device 1, since the second heater 14 for thermally welding the nonwoven fabric 103 to the filter body 102 at the end of the rotational movement is arranged extending in a direction orthogonal to the rotational movement direction, The nonwoven fabric 103 can be easily wound around the outer periphery of the filter body 102 while pulling without generating wrinkles. For this reason, the edge part of the nonwoven fabric 103 heat-welded with respect to the filter main body 102 is arrange | positioned in parallel with the axial direction of the filter main body 102, without arrange | positioning spirally. As a result, the tensile force acting on the nonwoven fabric 103 in the outer circumferential direction of the filter body 102 can be made more uniform in the direction parallel to the axial direction of the filter body 102, and the appearance quality can be further improved. Can do.

  Further, according to the winding device 1, since the third heater 15 disposed along the rotational movement direction is provided inside the pair of guide portions 12, the filter main body 102 even during the rotational movement of the filter main body 102. The nonwoven fabric 103 can be thermally welded to the filter body 102 over the circumferential direction. For this reason, wrinkles are less likely to occur during the rotational movement of the nonwoven fabric 103 wound around the outer periphery of the filter body 102. As a result, the appearance quality can be further improved.

  Further, according to the winding device 1, since the pair of third heaters 15 (15 a, 15 b) are provided so as to be adjacent to the inside of the pair of guide portions 12, the filter main body 102 is rotated during the rotational movement of the filter main body 102. It is possible to prevent an unstable force from being generated in a direction parallel to the axial direction of the filter body 102 on the nonwoven fabric 103 wound around the outer periphery of the filter 102. For this reason, wrinkles are less likely to occur during the rotational movement, and the appearance quality can be further improved.

  Further, according to the winding device 1, the filter main body 102 is disposed at the rotational movement start position only by positioning and arranging the filter main body 102 so as to abut the stopper 16, and the work is further facilitated. Will be planned. For this reason, the work efficiency can be further improved.

  Moreover, according to the winding device 1, the side opposite to the rotational movement start position between the pair of guide portions 12 is formed in an open state so that the filter body 102 around which the nonwoven fabric 103 is wound can pass. For this reason, the operator rotates the filter body 102 to wind the nonwoven fabric 103 around the outer periphery, and after performing heat welding on the second heater 14, the filter body 102 to which the nonwoven fabric 103 is wound and fixed is wound. It can be rotated as it is and taken out between the pair of guide portions 12. Thereby, the winding and fixing work and the taking-out work of the nonwoven fabric 103 can be performed quickly and continuously, and the work efficiency can be further improved.
