Description

  The present invention is a filter element that is installed inside an air conditioner in an automobile interior and is used by being mounted on a cabin filter for purifying outside air and inside air, or an air conditioner in a living environment such as a domestic air purifier or an air conditioner. For the purpose of removing gases such as package filters, fan coil units, central air conditioning filter units used in filters for the purpose of dust removal and deodorization, etc., or air purifiers installed in buildings, factories, offices, etc. The present invention relates to a filter element manufacturing method suitable for a gas removal filter and the like, and a filter element manufacturing jig used for manufacturing the filter element.

  Conventionally, a filter element that is installed inside an air conditioner in a car interior to clean the outside and inside air, or a filter element that is used by installing it in an air conditioner in a living environment such as a home air purifier or air conditioner. For the purpose of removing gas from package filters, fan coil units, central air-conditioning filter units, etc. used in filters for the purpose of dust removal and deodorization, or air purifiers installed in buildings, factories, offices, etc. A filter element used for a gas removal filter or the like includes a tape-like frame member fixed to an outer peripheral edge of a filter medium on which a pleat is formed, or a pleat and a linear separator with a pleat interval. Is known in which a tape-like frame material is fixed to the outer peripheral edge of the filter medium held by the above.

  These filter elements need to be replaced when their filter media reaches the end of their life. Filter elements or filter media constituting the filter elements are required to have various forms and sizes according to various applications and models. The Therefore, when manufacturing such a filter element, various types of filter elements must be produced with high accuracy and efficiency. In particular, in the process of manufacturing a filter element in which the frame material is fixed to the end face of the filter medium folded into a zigzag shape, the quality of the filter element depends on how accurately and efficiently the frame material is fixed to the end face of the filter medium. Because it is determined, there is a need for a way to do that.

  Conventionally, a method shown in FIG. 16 is known as a method for fixing a frame material to an end face of a filter medium that is folded into a zigzag shape in a filter element manufacturing process (see Patent Document 1). In this method, the filter medium 1 is formed into a continuous body which is folded into a zigzag shape, and the lateral strips 4a and 4b are supplied to the side of the filter medium 1 from the two rolls 2a and 2b via the pressing rollers 3a and 3b. At the same time, the side strips 4a and 4b are fixed to the side surfaces of the filter medium 1 by heat-pressing the side strips 4a and 4b to the side of the filter medium 1 by the pressing rollers 3a and 3b.

  However, according to this method, in addition to the step of fixing the side strips 4a and 4b to the side of the filter medium 1, the reinforcing strip on the upper plate of the filter medium 1 that is folded using the pressing rollers 6a and 6b. The filter element is manufactured through steps such as bonding of the pieces 5a and 5b, bonding of a rectangular strip (not shown), and attachment of an annular foam material sealing device (not shown). While it has the merit that the strips 4a and 4b can be fixed continuously, it requires various steps different from the fixing step of the side strips 4a and 4b to the side of the filter medium 1 described above, and further increases the productivity. There was a need for improvement.

  On the other hand, a method shown in FIGS. 17 and 18 is also known as a method for manufacturing a filter element (see Patent Document 2). In this method, a filter base material 11 pleated in a cross-sectional waveform is held between a pair of holding plates 15, the holding plate 15 is rotated to rotate the filter base material 11, and the rotating filter base 11 is rotated. By applying the application roller 14 to the outer peripheral edge of the material 11, the application roller 14 is driven to rotate in accordance with the rotation of the filter base material 11, and an adhesive is provided between the application roller 14 and the filter base material 11. The belt-shaped frame material 12 coated with the above is supplied, whereby the belt-shaped frame material 12 is wound around and bonded to the outer periphery of the filter base material 11 to manufacture a filter element.

However, this method has the following problems. That is,
(1)
Since the belt-like frame material 12 is fixed to the outer peripheral edge of the filter base material 11 by the pressing force of the sticking roller 14, sufficient heating and pressure cannot be applied to the frame material 12.
(2)
In order to hold the filter base material 11 between the pair of holding plates 15, first, the arm of the sticking roller 14 is raised to release the pressing force, and then the interval between the holding plates 15 is widened, and the filter base material 11 is interposed therebetween. And then the interval between the holding plates 15 is narrowed, and then the arm of the sticking roller 14 is lowered to apply a load to the outer peripheral edge of the filter base 11, and the filter The holding plate 15 corresponding to the filter base material 11 must be replaced each time depending on the shape and size of the base material 11, which requires a lot of labor and the holding plate according to the type of the filter base material 11. There was a problem that had to be prepared.
(3)
It is difficult to insert the filter base material 11 from the side into the gap between the pair of holding plates 15 provided in a standing state, and the filter base material 11 may be accidentally dropped. There is a problem that it is difficult to obtain a filter element with high dimensional accuracy because the weight easily shifts downward with respect to the holding plate 15.
(4)
Since a load is applied from the upper surface side of the holding plate 15, the holding plate 15 to be used needs to be made of a sturdy material. In addition, it is necessary to attach a large number of protruding pieces 13 to each pair of holding plates 15 with high accuracy, and there is a problem that the manufacturing cost of the holding plates 15 increases, resulting in an increase in product cost.

First, the jig used in the method of the present invention will be described.

  The jig 30 shown in FIGS. 3 to 11 is used when manufacturing the filter element 20 in which the tape-shaped frame material 22 is fixed to the outer peripheral edge of the filter medium 21 on which the pleats shown in FIGS. 1 and 2 are formed. The filter medium storage container 31 that stores the filter medium 21 and the lid member 32 that covers the upper surface opening of the filter medium storage container 31.

  The filter medium 21 is not particularly limited as long as pleats can be formed. For example, a nonwoven fabric, a woven fabric, a knitted fabric, paper, or a composite nonwoven fabric in which a reinforcing material is laminated can be used. As the non-woven fabric, for example, a binder-bonded non-woven fabric, a hydroentangled non-woven fabric, a needle punched non-woven fabric, a fiber-bonded non-woven fabric, a spunbonded non-woven fabric, a melt blown non-woven fabric, or paper can be used alone or as a non-woven fabric appropriately combined with these. . In the case of a melt blown nonwoven fabric, the fiber diameter is desirably 10 μm or less.

  The material of the nonwoven fabric is not particularly limited, and examples thereof include polyester fibers such as polyethylene terephthalate and polybutylene terephthalate, polyamide fibers such as nylon 6 (registered trademark) and nylon 6, 6 (registered trademark), polyethylene, and polypropylene. In addition to polyolefin fibers, acrylic fibers such as polyacrylonitrile, polyvinyl alcohol fibers, or synthetic fibers such as synthetic pulp, semi-synthetic fibers such as rayon, natural fibers such as cotton, pulp fibers and hemp, glass fibers, Ceramic fibers, metal fibers, and the like can be used alone or in combination as appropriate.

  Further, the filter medium 21 can be made multifunctional by including a functional material such as activated carbon, catalyst particles, or a deodorizing agent. The functional material is contained in a form that is kneaded or adhered to the fibers constituting the filter medium, or that is contained by a conventionally known method, such as bonding the fiber surface or between the fibers via a binder. It can be taken.

  As a method of forming pleats on the filter medium 21, there are a conventionally known method using a pleating machine such as a reciprocating type or a rotary type, and a method of pressing with a pressing die formed in a zigzag shape.

  The pleat height of the filter medium 21 is preferably 5 to 150 mm, more preferably 8 to 65 mm. The pitch of the filter medium 21 is preferably 1 to 100 mm, more preferably 2 to 50 mm.

  Further, the filter medium 21 can form pleats and can hold the interval between the pleats by a linear separator 21a. As the separator 21a, for example, a foamed or non-foamed resin solid material such as a hot melt resin or a urethane resin is used, and this resin solid material is the surface of the filter medium 21 (which may be one or both sides). It can form by apply | coating so that the fold line of pleat may be crossed. One, two or more separators 21 a can be formed in the width direction of the filter medium 21 according to the size of the filter medium 21. The separator 21a may be continuous or discontinuous, and may be formed on both the fluid inflow side and the outflow side of the filter medium 21, or may be formed only on one surface side.

  Next, the frame member 22 fixed to the outer peripheral edge of the filter medium 21 on which the pleats are formed will be described. As shown in FIGS. 5 and 10, the frame member 22 is fixed to the outer peripheral edge of the filter medium 21 formed with pleats, and fixes the pleat shape of the filter medium 21. For example, a sheet-like material such as a nonwoven fabric, a woven fabric, a knitted fabric, a film, a foamed resin plate, a resin thin plate, or a metal thin plate can be used. For example, if a non-woven fabric or a foamed resin plate is used as the frame material 22, the thickness of the frame material 22 becomes high and the cushioning property is obtained while maintaining a certain level of strength. When the element 30 is attached to a rigid frame for attachment (not shown), there is an advantage that high adhesion with the rigid frame can be secured. In addition, when a material having excellent cushioning properties such as a nonwoven fabric or a foamed resin plate is used as the frame member 22, there is an advantage that it is easy to adhere to the filter medium 21 containing a functional material such as activated carbon.

  The frame member 22 has a thermoplastic resin layer 22a on one surface thereof. Such a frame member 22 can be obtained by attaching an adhesive to the sheet material or laminating an adhesive sheet on the sheet material. When an adhesive is attached to the sheet material, the frame material 22 is made of hot-melt adhesive made of thermoplastic rubber such as ethylene vinyl acetate, thermoplastic polyurethane, polyamide, polyester, polyolefin, or styrene block polymer. It can be obtained by applying or spraying the agent on the sheet material. When laminating an adhesive sheet, it can be obtained by laminating a hot melt resin sheet on the sheet material.

  After the frame material 22 is manufactured as described above, the frame material 22 is cut into a tape shape corresponding to the pleat height of the filter medium 21 so that the outer peripheral edge of the filter medium 21 can be sealed without a gap. It is used for fixing to the outer peripheral edge.

  The jig 30 of the present invention is used when the filter element 20 is manufactured by fixing the frame material 22 to the filter medium 21, and the jig 30 shown in FIGS. 3 to 7 has the pleat shown in FIG. It is used when manufacturing the filter element 20 in which the frame material 22 is fixed to the outer peripheral edge portion of the formed filter medium 21, and the jig 30 shown in FIGS. 8 to 11 forms the pleats shown in FIG.

The material of the lid member 32 is preferably a metal such as iron, aluminum or stainless steel, or a plastic such as ABS, and particularly preferably lightweight aluminum or plastic. A comb tooth portion 33 is provided on the inner surface side of the lid member 32.

  The comb tooth portion 33 has a shape corresponding to the pleat shape of the filter medium 21 to be held, that is, the pleat height and the pleat pitch of the filter medium 21. For this reason, when the cover member 32 is put on the filter medium storage container 31 containing the filter medium 21, the filter medium 21 is engaged with the pleats of the filter medium 21 and comes into contact therewith, and the filter medium 21 is sandwiched between the bottom plate 31 a of the filter medium storage container 31 The pleated shape of the filter medium 21 is maintained. There may be at least one comb tooth portion 33 as long as it is on the inner surface side of the lid member 32, and the position and number thereof are not particularly limited. However, since the pleated shape of the filter medium 21 is held by the comb teeth 33 as described above, it is preferably provided at both ends on the inner surface side of the lid member 32 as shown in FIGS. 4, 5, and 6. Good. More preferably, the cover member 32 is provided at three positions, that is, both end portions on the inner surface side and the central portion. Thus, by providing the comb teeth portion 33 at both ends on the inner surface side of the lid member 32, or both ends and the center portion, the filter medium 21 is more reliably held.

  The lid member 32 may take a form having a wall 32a provided so as to be parallel to the fold line of the pleats of the filter medium 21 when the lid member 32 is put on the filter medium storage container 31. In such a form, for example, as shown in FIGS. 4 and 5, the filter medium 21 is arranged such that both ends of the filter medium 21 are outside the wall 31 b of the filter medium storage container 31, or the filter medium 21. Is placed so that both ends of the filter medium 21 are outside the wall 32a of the lid member 32, and is placed in the filter medium storage container 31, and the lid member 32 is covered in this state, so that both ends of the filter medium 21 are covered.
