Description

  The present invention relates to a stretch net collector, and more particularly to a stretch net collector that collects floating dust.

  In factories such as paint shops for automobiles, furniture, food manufacturing factories, precision machine manufacturing factories, electrical component manufacturing factories, etc., there is a collection net that collects dust, dust, paint mist, etc. in order to keep the manufacturing environment hygienic. It is extended. As disclosed in Japanese Patent Application Laid-Open Nos. 2002-233800, 3959485, 3131820, and 2007-6722, patent applicants can use a net substrate as a collection net. A product with a pressure-sensitive adhesive applied was developed.

  In order to extend these collection nets to the installation location, for example, as shown in FIG. 8, the wires 91 are extended from opposing wall portions near the indoor ceiling, and the mesh of the collection net 90 and the wires 91 are expanded. The catching net 90 is attached to the wire 91 by locking the hook 92 with a fine pitch, but the meshes of the catching net 90 and the wire 91 are sewn together with a thin string or the like. The collection net 90 is evenly attached to the wire 91.

  On the other hand, it is also conceivable to apply the method of attaching the screen door to the frame for the collection net. Specifically, as shown in FIG. 9, after the collection net 90 is accommodated in a frame body 95 extending in a rod shape, an elongated rubber 94 is pushed into the frame body 95 so that the collection net 90 is connected to the frame body 96. It is sandwiched between the pressing rubber 94. A lip portion 95a is attached to the open end portions of both side standing walls of the frame body 95 to hold the pressing rubber 94. When the frame body 95 to which the collection net 90 is attached is fixed to the wall near the ceiling in the room, the collection net 2 is extended in the extending direction of the frame body 96.

  By the way, if the collection net is extended indoors, it gradually becomes dirty with dust. For this reason, it is necessary to replace it with a new one periodically.

  However, in the first method, when replacing the collection net, it is necessary to remove the hooks 92 attached directly from the collection net 90 one by one, which is troublesome. In addition, since the collection net 90 is not correctly extended, vertical wrinkles may enter the collection net 90, the mesh may not be sufficiently opened, and the entire net may be wavy. In such a collection net that is not properly deployed, dust collection efficiency was low.

  In the second method, since the pressing rubber 94 is held by the lip portion 95 a attached to the frame body 95, the work of entering and removing the pressing rubber 94 into the frame body 95 is troublesome. In addition, since the screen has four sides of the net held by the frame, the net is not easily detached, and the load applied to the pressing rubber is not so large. On the other hand, when the frame body 95 used in the screen door is applied to the extension of the collection net 90, the frame 95 holding the upper portion of the collection net 90 has a collection net 90. Therefore, the large and heavy collection net 90 is easily detached from the frame body 95 and the pressing rubber 94, and cannot be reliably suspended. Originally, the collection net 90 is large in size, and is used while partitioning a large factory space. For this reason, it is impossible to sandwich and extend the four sides of the collection net 90 between the long pressing rubber 94 and the frame body 95, and it takes a lot of trouble to replace the collection net 90. It was almost impossible, and it was impossible to open the collection net 90 properly and expand it.

  Accordingly, the inventor has eagerly searched for a stretched net collector that can be easily replaced by utilizing the characteristics of a collection net formed by applying an adhesive to a net base material.

  The present invention has been made in view of such circumstances, and is to provide a stretched net collector that can simply perform a replacement operation of a collection net and can correctly expand the collection net. Let it be an issue.

  (1) The stretch net collector of the present invention includes a collection net formed by applying a pressure-sensitive adhesive to a net base material having a mesh, and a stretch tool for holding the collection net in a correctly stretched state. An extension net collector, the extension tool extending along an arrangement direction of the mesh of the net base material, and a frame having an accommodation recess for accommodating the collection net; and an extension direction of the frame body And an accommodating member that enters the accommodating recess and sandwiches the collection net with the frame, and the accommodating recess of the frame includes an inner bottom surface and both end portions of the inner bottom surface The housing member has a pair of outer side surfaces facing the pair of inner side surfaces of the frame body, and the pair of inner side surfaces of the frame body And the pair of outer side surfaces of the housing member are the collection Characterized in that in close contact with the slip effect adhesive strength of the pressure-sensitive adhesive of the net as by uneven network structure of the net base.

  According to the above configuration, the collection net is held between the frame and the housing member. The accommodation recess formed in the frame body accommodates the collection net and the accommodation member, and the collection net is sandwiched between the frame body and the accommodation member. The collection net is a net base material coated with an adhesive. For this reason, the inner surface of the frame and the outer surface of the housing member are in close contact with each other due to the adhesive force of the adhesive of the collection net and the anti-slip effect due to the uneven network structure of the net substrate. Therefore, the collection net is held by the frame body and the housing member, so that the net is correctly opened in a state of opening the mesh.

  The housing recess of the frame body is surrounded by an inner bottom surface and a pair of inner side surfaces extending in the vertical direction from the inner bottom surface, and the housing member has a pair of outer side surfaces along the pair of inner side surfaces of the frame body. . For this reason, it becomes easy to advance and retract the collection net and the accommodation member in the accommodation recess, and the workability for replacing the collection net is good. In addition, the contact area of the housing member with the frame increases, and the collection net can be firmly fixed.

  In addition, in order to replace the collection net with a new one, one end of the housing member is gripped and removed from the housing recess. Then, the whole storage member is removed from the storage recess. After the housing member is removed, the collection net can be easily removed from the housing recess. Then, a new collection net is accommodated in the accommodating recess of the frame, and the collection net is pressed against the frame by the accommodating member. As a result, the new collection net is fixed between the frame body and the housing member by the adhesive force of the adhesive and the anti-slip effect due to the uneven mesh structure of the net substrate.

  In the present invention, the adhesive strength of the pressure-sensitive adhesive and the concavo-convex network structure of the net substrate can be obtained without any structural ingenuity for integration of the frame, the housing member, and the collection net. It is integrated by. Therefore, the shapes of the frame and the housing member can be simplified, the collection net can be correctly extended, and the collection net can be easily replaced.

  (2) The frame body has the U-shaped housing recess that is surrounded by the inner bottom surface and the pair of inner side surfaces and opens on one side, and the housing member includes an outer bottom surface and both end portions of the outer bottom surface. A U-shaped space portion that is surrounded by a pair of outer surfaces extending in the vertical direction from one side and that opens on one side, and the inner bottom surface of the frame body is disposed on the opening side of the space portion of the housing member. It is preferable that

  In this case, it becomes easy to advance and retract the collection net and the accommodation member to the accommodation recess. In addition, when fitting a fitting such as a hook or locking tool into the bottom of the frame, a part of the fixture can be projected into the housing recess without interfering with the housing member. The tool can be securely fixed to the frame.

  (3) It is preferable that the collection net is sandwiched by the entire portion of the pair of inner side surfaces of the frame body and the pair of outer side surfaces of the housing member facing each other. In this case, the collection net is disposed on the entire portion of the pair of inner side surfaces of the frame body and the pair of outer side surfaces of the housing member facing each other. For this reason, it is possible to firmly adhere the entirety of the mutually facing portions of the pair of inner side surfaces of the frame body and the pair of outer side surfaces of the housing member by the adhesive force of the adhesive and the uneven network structure of the net base material. it can.

  (4) It is preferable that the extension tool holds a pair of opposite end edges of the collection net. In this case, since the pair of opposite edge portions of the collection net are held by the extension tool, the entire collection net can be nicely extended.

  (5) The net base material has net legs that pass through arcs adjacent to each other while the monofilament made of thermoplastic resin draws an arc, and has a loose space formed by the arc, and between the net legs. It is preferable that a network is formed by connecting in parallel with thermoplastic monofilaments, and the inside of the network is partitioned into an oblique shape, a parallel shape or an X shape with the thermoplastic monofilament.

  In this case, the pressure-sensitive adhesive film has a large area, and the pressure-sensitive adhesive film area can be formed efficiently and widely. For this reason, adhesion of minute dust and the like is improved, and the amount of captured dust and the like that passes is increased. Further, since the adhesive film is randomly generated, the amount of collected dust and the like increases as a whole regardless of the size of the dust and the like.

  In addition, by using a thermoplastic synthetic resin monofilament, the surface of the monofilament can be smooth and exhibit rigidity. In addition, the collection net can be correctly developed into a desired mesh shape by being correctly extended with an extension tool attached to the upper and lower end edges thereof. By these things, the permeability | transmittance of the air of a collection net | network becomes favorable and the amount of dust collection can be increased, without inhibiting the passage of air.

  According to the stretch net collector of the present invention, the collection net formed by applying an adhesive to the net base material is housed in the housing recess formed in the frame body, and is sandwiched between the frame body and the housing member. The collection net is fixed integrally with the frame body and the housing member in the vertical direction by the adhesive strength of the adhesive and the rugged mesh structure of the net base material. For this reason, the collection net can open a mesh in a desired shape, and a new exchange of the collection net can be easily performed. In addition, the entire collection net can be correctly extended to improve dust collection efficiency, and the used collection net with dust attached can be easily replaced with a new one.

It is principal part sectional drawing of the expansion | deployment net collection body concerning another prior art example.

  Embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, a plurality of stretch net collectors 1 according to this embodiment are arranged in series at a factory installation location. Each extension net collector 1 includes a collection net 2 and an extension tool 3 provided on the upper and lower edge portions of the collection net 2. The collection net 2 is correctly extended by the extension tool 3. Here, “correctly stretched” means that the net of the collection net 2 is not distorted, and in a state where the net is unfolded, there is no wrinkle, and no wavy irregularities are produced. It means that the net 2 is extended.

  As shown in FIG. 2, the collection net 2 includes a net substrate 21 having a mesh 20 and an adhesive 28 applied to the net substrate 21.

  The net base material 21 has a desired width and is long and flexible. In the present embodiment, the width and height of the net base material 21 are 2 m and 3 m. The net substrate 21 is knitted with monofilaments, multifilaments, or aggregates (twisted yarns) of thermoplastic resin such as vinyl chloride, vinylidene chloride, polyolefin, nylon, and the like. Among synthetic resins, thermoplastic resins are relatively easy to reuse (recycle). Among them, when using vinyl chloride or vinylidene chloride nets, even if dust or the like adheres to nylon or polyolefin, etc. The reusability is not hindered and the reusability is extremely easy and has the highest utility value. On the other hand, the use of a net such as polyolefin or nylon improves the handling and strength.

  As the network structure of the net base material 21, for example, a flat weave, a raschel weave, a cocoon or weave found in a fish net, a knotless weave, a twisted net, or the like may be used. Any of the rhombuses which are squares whose corners are not right angles may be used. Preferably, the mesh of the net base material 21 is square.

The adhesive 28 is applied to the net base material 21. As the adhesive 28, acrylic, natural rubber, SBR, block SIS, silicon rubber, or the like is preferably used because of high adhesive force and a long adhesive force duration. The performance of the adhesive 28 is preferably in the following range.
Adhesive strength (g) 200-700 (conforms to JIS Z0237)
P. Tack (g) 200-700 (conforms to JIS Z0237 reference column)
Peeling force (g) 5-20 (conforms to JIS Z0237)
Ball tack 5-20 (conforms to JIS Z0237)
The mesh size in the net substrate 21 will be described. As shown in FIG. 3, for example, one mesh 20 is usually formed by four mesh legs 25, and the length of a pair of mesh legs 25 facing each other is L, and the mesh legs 25 When the apparent diameter (diameter) is D, the length of the other pair of opposite mesh legs 25 is L ′, and the apparent diameter of the mesh legs 25 is D ′, the area is surrounded by L and L ′. The gap K becomes the mesh 20. Here, (1) 0.1 mm ≦ D <2.5 mm, (2) 2.0 mm ≦ L <8.0 mm, and (3) 2 <L / D <35 is preferable. In this case, the trapping net 2 has good air permeability, and air including dust and the like is effectively filtered by the net legs 25 of the net base material 21, so that the trapped amount of floating dust and the like is reduced. Can greatly increase.

  The adhesive 28 is attached to the net legs 25 of the net base material 21. An adhesive 28 is attached to the periphery of the mesh 20 of the net base material 21 and the central portion of the mesh 20 is opened. Air passes through the central portion opened in the mesh 20. At this time, dust floating in the air is caught by the mesh legs 25 attached around the mesh 20 and collected by the adhesive 28.

The adhesion amount of the adhesive 28 to the net base material 21 is preferably 50 to 180 g per 1 m ² of the net base material, and more preferably 100 to 150 g. In this case, a sufficient amount of the adhesive 28 adheres to the net base material 21 so that the frame 5 and the housing member 6 can be firmly adhered.

  Further, as shown in FIG. 4, a pair of opposite mesh legs 25 may be connected by a bridging portion 26 that crosses the mesh 20 in a parallel shape, an oblique shape, or an X shape. In this case, dust collection efficiency is further improved. Moreover, the adhesion amount of the adhesive 28 with respect to the unit area of the net base material 21 is increased, and the collection net 2 can be more firmly adhered to the frame body 5 and the housing member 6.

  The net base material 21 has a mesh leg 25 having a loose space formed by an arc formed by a thermoplastic resin monofilament passing through adjacent arcs. A plurality of mesh legs 25 are connected in parallel with thermoplastic monofilaments to form a mesh, and the inside of the mesh is a relatively narrow bridge portion that is slanted, parallel, or X-shaped with thermoplastic monofilaments. May be. In this case, the adhesive film has a large area, the adhesion of fine dust and the like is improved, and the trapped amount of dust and the like that passes through becomes large. Furthermore, since the adhesive film is randomly generated, the amount of dust and the like captured increases as a whole regardless of the size of the dust and the like. In addition, by using monofilament made of thermoplastic synthetic resin, the surface of the monofilament can be made smooth and exhibit rigidity, which improves the air permeability and obstructs the passage of air in areas other than desired. There is nothing to do. Since the filament has rigidity, it can form the loop shape of the mesh leg portion, and can be easily held, and can form the coating film area of the adhesive efficiently and widely.

  As shown in FIG. 5, the spreader 3 includes a frame body 5 and a housing member 6. The frame 5 is made of an aluminum material, extends linearly, has a U-shaped cross-sectional shape, and has an accommodating recess 50 inside. As shown in FIG. 1, the frame 5 is disposed along the arrangement direction L of the mesh 20 of the net base material 21. That is, the frame body 5 is disposed along the extending direction of the mesh legs 25 constituting the mesh 20. Here, “along the arrangement direction of the mesh 20” includes not only a direction parallel to the arrangement direction L of the mesh 20 but also a case where the mesh 20 is slightly inclined. For example, an error within ± 20 °, preferably within ± 10 ° with respect to the arrangement direction of the mesh 20 is allowed. Similarly, a slight inclination with respect to the direction in which the net legs 25 extend is allowed “along the direction in which the net legs 25 extend”.

  As shown in FIG. 5, the frame 5 has a U-shaped cross-sectional shape, and includes an inner bottom surface 5b and a pair of inner side surfaces 5a provided upright from both ends of the inner bottom surface 5b. The width, height, and length of the outer shape of the frame 5 are, for example, 15 mm, 15 mm, and 2 m, and the thickness of the frame 5 is 2.0 mm.

  The housing member 6 is made of an aluminum material and has a U-shaped cross-sectional shape having a size that can be housed in the housing recess 50 of the frame body 5. The housing member 6 includes an outer bottom surface 6b and a pair of outer side surfaces 6a erected from both ends of the outer bottom surface 6b. The width, height, and length of the outer shape of the housing member 6 are 10 mm, 10 mm, and 2 m, and are almost similar to the frame body 5. The entire pair of outer surfaces 6 a erected from both ends of the outer bottom surface 6 b of the housing member 6 face the entire pair of inner surfaces 5 a of the U-shaped frame 5. Between the pair of outer side surfaces 6 a of the housing member 6 and the pair of inner side surfaces 5 a of the frame body 5, there is an interval substantially equal to the thickness of the collection net 2. In the present embodiment, a gap with a thickness A of 0.5 mm is provided between the outer side surfaces 6 a on both the left and right sides of the housing member 6 and the inner side surfaces 5 a on the left and right sides of the frame 5. The collection net 2 is disposed in this gap.

  The housing member 6 extends in parallel with the extending direction of the frame body 5 and enters the housing recess 50 to sandwich the collection net 2 with the frame body 5. The pair of inner side surfaces 5 a of the frame body 5 and the pair of outer side surfaces 6 a of the housing member 6 are due to the adhesive force of the adhesive 28 of the collection net 2 and the anti-slip effect due to the concavo-convex network structure of the net base material 21. It is in close contact. The net base material 21 is formed with a concavo-convex shape by a mesh 20 and a knitting leg 25 surrounding the mesh 20. Due to this uneven shape, the collection net 2 is securely held between the frame 5 and the housing member 6 without slipping, and even if the collection net 2 is pulled by hand in a direction away from the frame 5 and the housing member 6. The frame body 5 and the housing member 6 are firmly held to such an extent that they do not slide out.

  The net 2 for collection is anti-slip by the adhesive force of the adhesive 28 adhering to the net base material 21 and the concavo-convex network structure of the net base material 21 with respect to the upper stretcher 3 and the lower stretcher 3. Held by the effect. For safety, the upper edge of the collection net 2 may be tied to the stretcher 3 with an insulation lock or a string.

  As shown in FIGS. 1 and 5, the extension tool 3 provided at the upper edge of the collection net 2 has hook members 58 formed in an endless shape at two locations on the upper portion of the frame 5. ing. Each hook member 58 is connected to a locking tool 59 that is curved in a semicircular arc shape. Both ends of the locking device 59 are inserted into the mounting holes 5m formed in the frame body 5 and protruded from the inner bottom surface 5b of the frame body 5 to the receiving recess 50 by about a few millimeters. It is fixed by bolt fastening. The inner bottom surface 5 b of the frame body 5 is disposed on the opening side of the space portion 66 formed inside the housing member 6. For this reason, the locking tool 59 slightly protruding from the inner bottom surface 5 b of the frame body 5 does not interfere with the housing member 6 and can be reliably fixed to the frame body 5.

  A wire 7 having a diameter of about 3 mm is fixed to the wall of the room. The stretch net collector 1 is attached to the wire 7 by the hook member 58 being extrapolated to the wire 7. A plurality of stretch net collectors 1 are attached to the wire 7 in series. A pipe may be used in place of the wire 7.

  Next, the manufacturing method of a stretch net base material is demonstrated. First, as shown in FIG. 6, the upper edge of the collection net 2 is applied to the opening side of the housing recess 50 of the frame 5. The extending direction of the frame 5 is aligned in parallel with the mesh arrangement direction L of the net base material 21 of the collection net 2. At this time, the collection net 2 is preferably arranged so as to protrude from the frame 5 by a slight width (for example, about 20 mm).

  Next, the housing member 6 is caused to enter the housing recess 50 to which the net base material 21 is applied, and the housing member 6 is pressed toward the inner bottom surface of the frame body 5. Thereby, the collection net 2 is sandwiched between the housing member 6 and the frame body 5, and the pair of inner side surfaces 5 a of the frame body 5 and the pair of outer side surfaces 6 a of the housing member 6 are collected by the collection net. The adhesive 28 is adhered and fixed by the adhesive force of the adhesive 28 and the anti-slip effect of the net substrate 21 having an uneven mesh structure. It should be noted that the appearance of the collection net 2 protruding from the frame 5 is cut off with scissors or a knife.

  When the collection net 2 is used for a predetermined period, dust adheres and becomes dirty. Therefore, it is preferable to replace with a new one after a predetermined period. A method for replacing the collection net 2 with a new one will be described. First, as shown in FIG. 7, the end 60 of the housing member 6 is gripped and removed from the frame body 5. Since the housing member 6 is a rigid body, the entire housing member 6 is detached from the frame body 5 by removing the end 60 of the housing member 6 from the frame body 5. After the housing member 6 is detached, the collection net 2 is removed from the frame 5. Since the adhesive is attached to the collection net 2, when the collection net 2 is removed from the frame body 5, a slight load is applied so that the collection net 2 is pulled out from the frame body 5. It can be easily removed. Thereafter, the spreader 3 is attached to the new collection net 2 according to the above attachment method.

The holding power of the collection net 2 to the spreader 3 was evaluated. In the evaluation, the apparent diameter D of the net legs 25 of the net base material 21 is 0.1 mm or more and less than 2.5 mm, the length L of the net legs 25 is 2.0 mm or more and less than 8.0 mm, and L / D is More than 2 and less than 35. The adhesion amount of the adhesive 28 to the net base material 21 was set to 50 to 180 g per 1 m ² of the net base material. The width, height, and length of the outer shape of the frame 5 of the stretcher 3 were 15 mm, 15 mm, and 2 m, and the thickness of the frame 5 was 2.0 mm. The width, height, and length of the outer shape of the housing member 6 are 10 mm, 10 mm, and 2 m, so that the housing member 6 has a substantially similar shape. The collection net 2 was sandwiched between the frame 5 and the accommodation member 6 by pressing the accommodation member 6 with a hand against the frame 5 to which the collection net 2 was applied. Thereafter, an attempt was made to pull out the collection net 2 from the extension tool 3 by hand, but the collection net 2 could not be pulled out at all. Further, when the extension net collector 1 formed by holding the collection net 2 on the extension tool 3 was extended indoors, the floating dust could be sufficiently collected.

On the other hand, when the adhesion amount of the adhesive 28 to the net base material 21 is changed to less than 50 g per 1 m ² of the net base material, when the collection net 2 is pulled out from the stretcher 3, Net 2 was pulled out slightly. Thus, even if the entire collection net 2 did not fall, the entire shape was distorted, the mesh was not sufficiently stretched, and the dust collection performance was also deteriorated.

  In the present embodiment, the collection net 2 is sandwiched between the rod-shaped frame 5 and the housing member 6. The accommodation recess 50 formed in the frame 5 accommodates the collection net 2 and the accommodation member 6, and the collection net 2 is sandwiched between the frame 5 and the accommodation member 6. The collection net 2 is obtained by applying an adhesive 28 to a net base material 21. For this reason, the inner surface 5 a of the frame 5 and the outer surface 6 a of the housing member 6 are brought into close contact with the adhesive 28 of the collection net 2.

  Furthermore, the net base material 21 has an uneven shape with a network structure. For this reason, the collection net 2 is prevented from coming out between the frame 5 and the housing member 6. Therefore, the collection net 2 is held in a state in which the collection net 2 is correctly extended by the frame body 5 and the housing member 6.

  Further, the pressure-sensitive adhesive 28 attached to the collection net 2 without any structural contrivance for integration of the frame body 5, the housing member 6 and the collection net 2 such as concavity and convexity. And the anti-slip effect due to the mesh irregularity shape of the net base material 21. Therefore, the shapes of the frame 5 and the housing member 6 can be simplified, and the workability for replacing the collection net 2 is excellent.

  Further, the extension tool 3 is installed at both upper and lower end edges of the collection net 2. For this reason, the entire surface of the collection net 2 is almost flattened, the mesh is opened correctly, the entire collection net 2 is properly expanded, and there are few gaps between the expansion net collection bodies 1. It is possible to prevent dust from slipping through the front and back of the stretch net collector 1 with the collector 1 as a boundary.

  In the above embodiment, the spreader 3 is installed at both upper and lower end edges of the collection net 2, but it can also be installed only at the upper end edge.

  The present invention is installed in any place where hygiene is required. For example, it is effectively used in factories such as painting plants for automobiles, furniture, etc., food manufacturing factories, precision machine manufacturing factories, and electrical component manufacturing factories.
