Since both of the first and second shading members are continuous members, a picture can be drawn easily on the entire surface thereof.

Description

TECHNICAL FIELD The present invention relates to a shielding device, a manufacturing method thereof, and a manufacturing device thereof

The present invention relates to a shielding device, a method of manufacturing the same, and a manufacturing device thereof, and more particularly, to a shielding device such as a blinder cordion curtain, a manufacturing method, and a manufacturing device thereof. Background art

In recent years, with increasing interest in interiors, interior-like colors have become deeper in blinds and room partitions, and high design is required. For this reason, blinds using, for example, nonwoven fabrics have been put into practical use instead of conventional aluminum materials.

An example of this blind is shown in FIGS. 15 to 17.

The blind 60 shown in FIG. 15 has a plurality of blind members ₆₃ each of which extends in the direction perpendicular to the paper surface and is provided with sheets 61 and 62 arranged opposite to each other. Is made of non-woven fabric, for example, and the opposite left and right end portions 64 and 65 are joined by pressure bonding or application of an adhesive. Further, each of the blind members 63 is vertically stacked, and the contact portions 66 with the adjacent blind members are joined by pressure bonding or application of an adhesive. As a result, the blind 60 can expand and contract vertically. FIG. 6 shows a state in which the blind 60 is folded. An end cap 67 is attached to the blind member 63 at the end.

The blind 70 shown in FIG. 17 includes a plurality of hexagonal prism-shaped blind members 7I extending in a direction perpendicular to the plane of the paper. Each of the blind members 71 is made of, for example, a nonwoven fabric, and is vertically stacked. The bent portion 71 a at the end of each blind member 71 is joined to the adjacent blind member 71. '

In the conventional blind, a vertical load such as an automatic load acts on the joint when used. The accordion curtain shown in Fig. 15 to Fig. 17 is used as an accordion curtain. When used, a lateral load acts on the joint in the same way when opening and closing. For this reason, high bonding strength is required at the bonding portion. If the strength is insufficient, problems such as detachment of each blind member may occur.

Also, due to design requirements, it may be desired to paint a picture, such as a landscape painting, over the entire blind. However, in the above-described conventional configuration, since a plurality of blind members are used, after each of the blind members is joined, a drawing force using a color spray or the like, or an entire image is disassembled and drawn on each of the blind members. Later, each blind member must be joined so as to compose one picture as a whole. In each of these cases, the work is very tedious and time-consuming.

An object of the present invention is to provide a shielding device having high strength and capable of easily improving the design, a method for manufacturing the same, and a device for manufacturing the same. Disclosure of the invention

A shielding device according to an aspect of the present invention includes first and second shielding members and a plurality of connecting members. The first shielding member is an elastic bellows-shaped member. The second shielding member is a member that is disposed to face the first shielding member and that can extend and contract. The connecting member is disposed between the first and second shielding members, and connects the two shielding members.

Here, since the first and second shielding members themselves are in a bellows shape with the expansion and contraction I, the load during use directly acts on the first and second shielding members. Therefore, the strength in the load action direction is high. Further, since both the first and second shielding members are continuous members, a picture can be easily drawn on the entire surface. For example, the design can be easily improved by adding a patterned fabric.

A method for manufacturing a shielding device according to another aspect of the present invention includes the following steps.

◎ A step of preparing a sheet-shaped first shielding member and a second shielding member.

◎ A step of arranging the first and second shielding members facing each other at a predetermined interval.

◎ A connecting step of connecting the opposing portions of the first shielding member and the second shielding member at predetermined intervals by a connecting member.

Here, in a state where the first and second shielding members are arranged to face each other, the connection is performed by the connecting member. Is tied. Thereby, the shielding device can be easily manufactured. In addition, the load on the shielding member directly acts on the first and second shielding members, and the durability is improved. In addition, since a continuous shielding member is used, for example, it is possible to reduce the raw material of the pattern, and it is possible to provide a shielding device with high design.

A manufacturing apparatus for a shielding device according to still another aspect of the present invention includes a transport mechanism, a concave / convex portion forming mechanism, a connecting member supply mechanism, and first and second joining mechanisms. The carrying mechanism is a mechanism capable of delivering the sheet-shaped first shielding member and the second shielding member in a first direction approaching each other. The concavo-convex portion forming mechanism is a mechanism for alternately forming a convex portion and a concave portion extending in a second direction intersecting the first direction at predetermined intervals on each of the first shielding member and the second shielding member. It is. The connection member supply mechanism is a mechanism for supplying a connection member having a predetermined width onto the first shielding member conveyed by the conveyance mechanism. The first joining mechanism is a mechanism for joining one end of the connecting member to the concave portion of the first shielding member. The second joining mechanism is configured such that the first shielding member and the second shielding member are arranged at a position close to each other by a predetermined distance by the transport mechanism, and the other end of the connecting member having one end joined to the first shielding member. This is a mechanism for joining to the concave portion of the second shielding member.

Using this manufacturing apparatus, the shielding device can be easily manufactured. In particular, since the connecting member can be joined to each shielding member while transporting each shielding member, continuous work becomes possible, and mass production is facilitated. These and other objects and advantages of the present invention will become more apparent from the following detailed description. BRIEF DESCRIPTION OF THE FIGURES

Blind composition

FIG. 1 shows a blind according to one embodiment of the present invention.

The blind 1 includes an extendable blind member 2 arranged vertically. The blind member 2 has shielding members 3 and 4 that are arranged at predetermined intervals in a vertical direction. Each of the shielding members 3 and 4 is a member extending in the up-down direction and the left-right direction, and is made of, for example, a nonwoven fabric, a natural material, a leather fabric, or a chemical fiber. As shown in FIG. 2, the shielding members 3 and 4 are formed with concave folds 3a and 4a and convex folds 3b and 4b, respectively. The concave folds 3a and 4a of the shielding members 3 and 4 and the convex folds 3b and 4b are opposed to each other. In addition, a connecting member for connecting the two members 3 and 4 is provided on the opposing portion of each of the concave folds 3a and 4a by a general bonding, a laminating process, an impulse process, a soldering process, an ultrasonic process, or the like. They are joined by pressure bonding or adhesive. Folded portions 5 a are formed at both ends of each connecting member 5, and the turned portions 5 a are joined to the inner surfaces of the shielding members 3 and 4. A picture 6 is drawn on the shielding member 3 or 4 of the blind member 2. As described above, when drawing a picture or a pattern on the shielding members 3 and 4, it is sufficient to use a patterned fabric as the shielding members 3 and 4, thereby easily designing the surface of the blind 1. be able to.

Above the blind member 2, a rail 7 is provided. The upper ends of the shielding members 3 and 4 are fixed to the lower part of the rail 7. Brackets 8 are provided at both ends of the rail 7. The rail 7 is attached to the wall of the window frame, for example, by the bracket 8. End caps 9 are fixed to the lower ends of the shielding members 3 and 4. c In addition, hanging strings 10 (FIG. 2) are vertically arranged at both ends in the left-right direction in the blind member 2. The lower end of each hanging string 10 is attached to an end cap 9 as shown in FIG. The upper end of each hanging string 10 is connected to an operation rod 11 provided outside. By pulling the operating rod 11, the end cap 9 can be raised and the blind member 2 can be folded (see FIG. 4).

As described above, since each of the shielding members 3 and 4 constituting the blind member 2 is formed of a member extending in the up-down direction and the left-right direction, the vertical direction acting on the blind member 2 (see the arrow in FIG. 2) ) Does not act on the connecting member 5 but acts on each shielding member 3 and 4 itself. For this reason, the strength of the blind member 2 is improved.

Blind member manufacturing equipment

FIG. 5 shows an outline of an apparatus for manufacturing a blind member.

In FIG. 5, rolls 15 and 16 around which a nonwoven fabric sheet serving as a raw material is wound are disposed at both left and right ends of the apparatus. The spindles I7 and 18 of the rolls 15 and 16 are rotatable in the directions of the arrows, respectively. Also, above the rolls 15 and 16, the sheets 15 a and 16 a (corresponding to the shielding members 3 and 4) wound around the π-rolls 15 and 16 are sent out, respectively. A delivery π-layer 19 and 20 is provided. Each of the feed rollers 19 and 20 is rotatable by a drive mode (not shown). Between the rolls 15 and 16, there are provided support blocks 21 and 22 for supporting the respective sheets 15 3 and 16a sent from the rolls 15 and 16 in the horizontal direction from below. I have. Each support block 21 and 22 Each of the members is a member extending in the front-rear direction, and is disposed at a predetermined interval in the horizontal direction. Both ends 2 la and 22 a of the support blocks 21 and 22 are formed at acute angles (see FIG. 6). Further, concave portions 23 and 24 and convex portions 25 and 26 extending in the front-rear direction are formed on each of the support blocks 21 and 22 respectively. Between the rolls 15 and 16, the crimp block 30 for crimping by ultrasonic processing, impulse processing, ゥ elder processing, etc. is provided on the rear side of the rolls 15 and 16 (the back side of the paper in FIG. 5). And folding blocks 31 and 32 arranged on both sides thereof. The crimp block 30 is arranged between the support blocks 21 and 22. The crimp block 30 is connected to a drive source (not shown) via a converter. At the center of the lower part of the crimping block 30, there is formed a projection 30a (FIG. 6) projecting downward and extending forward and backward. On the other hand, the connecting member 5 is supplied from a supply device (not shown) to the opposing portions of the support blocks 21 and 22. The connecting member 5 is placed on each of the sheets 15a and 16a between the support blocks 21 and 22. The crimping block 30 can be advanced and retracted by a driving device such as a cylinder or the like, and can slide on the connecting member 5 in the front-rear direction in a state where the protrusion 30 a is pressed against the connecting member 5. As a result, both ends of the connecting member 5 are bent and pressed onto the respective sheets 15a, 16a to be joined. When a natural material, leather cloth, cotton fabric product, or a sheet made of chemical fiber is used as the raw material, for example, an adhesive is applied between both ends of the connecting member 5 and the raw material. At the lower part of the bending block 31, a convex portion 34 and a concave portion 35 (FIG. 6) which can be engaged with the concave portion 23 and the convex portion 25 of the support block 21, respectively, are formed. Similarly, a lower portion of the bending block 32 is formed with a convex portion 35 and a concave portion 36 which can be engaged with the concave portion 24 and the convex portion 26 of the support block 22, respectively. Further, each of the bending blocks 31 and 32 can be advanced and retracted by a driving device such as a cylinder similarly to the crimping block 30 (see FIG. 5—dashed line).

At the time of manufacturing, first, the rolls 15 and 16 and the feed π-rollers 19 and 20 are rotated to send out the sheets 15 a and 16 a, and the fed sheets 15 a and The respective end surfaces of 16a are arranged to face each other on the support blocks 21 and 22. Next, the connecting member 5 is supplied by a supply device (not shown), and the sheets 15a and 16a are opposed to each other. To be placed. From this state, the cylinder is driven to slide the crimping block 30 and the bending blocks 31 and 32 forward. When the crimp block 30 is moved, the protrusion 30 a at the lower portion of the crimp block is pressed against the connecting member 5. Thereby, the folded portions 5a are formed at both ends of the connecting member 5, and the folded portions 5a are pressed against the sheets 15a and 16a, respectively. On the other hand, when crimping is performed by, for example, ultrasonic processing, mechanical energy from a converter (not shown) is supplied to the crimping block 30 by driving the cylinder, and ultrasonic vibration is applied. Due to the ultrasonic vibration of the crimp block 30, frictional heat is generated between the folded portion 5a of the connecting member 5 and each of the sheets 15a, 16a pressed against the folded portion 5a from below, and the folded portion 5a And the respective sheets 15a and 16a are fused.

When the bending block 31 is moved, the concave portion 35 and the convex portion 34 at the lower portion of the bending block 31 are engaged with the corresponding support block 21 side convex portion 25 and concave portion 23, respectively. As a result, the sheet 15a is bent between the concave portions and the convex portions. Similarly, the convex portion 35 and the concave portion 36 at the lower part of the bent block 32 are engaged with the corresponding support block 22 side concave portion 24 and convex portion 26, respectively. As a result, the sheet 16a is bent. The shape of the bottom of each of the recesses 23, 24, 35, 36 of the support blocks 21, 22, and the bent blocks 31, 32, and the tip of each of the recesses 25, 26, 34, 35 The shape of the part may be an R shape. As a result, as shown in FIG. 7, each of the folds 3a, 3b and 4a, 4b formed in each of the shielding members 3 and 4 after bending can be rounded, and the entire blind can be made to have a sense of volume and volume. It can give a feeling of foot.

Next, the spindles 17, 8 and the feed rollers 19, 20 are rotated, and the sheets 15a, 16a are fed from the rolls 15, 16 respectively. The feed amount of each sheet 15 a. 16 a is set so that each convex fold 40, 41 is arranged at each end 2 la, 22 a of each corresponding support block 21, 22. Is done. From this state, the connecting member 5 is supplied in the same manner as described above, and the joining and bending of the connecting member 5 are performed by moving the pressure bonding block 30 and the bending blocks 31 and 32.

Hereinafter, similarly, each sheet 15a, 16a is gradually removed from each roll 15 and 16. The joining of the connecting member 5 by the crimping block 30 and the bending of each of the sheets I5a and 16a by the bending blocks 31 and 32 are performed continuously. Thereafter, the blind member 2 is formed by attaching the hanging string 10.

When the blind member 2 is manufactured, if an end cap 9 is attached to a lower portion of each of the shielding members 3 and 4 at an early stage of the manufacturing (see FIG. 6), the weight of the end cap 9 is reduced. The sheets 15a and 16a can be easily sent out. C In this case, for example, an original material of a patterned material is used as each of the sheets 15a and 16a constituting the shielding members 3 and 4. In this case, the painting on the blind member 2 can be easily performed.

(Modified example)

In the manufacturing apparatus shown in FIGS. 5 and 6, the crimping block 30 and the bending blocks 31 and 32 are arranged on the rear side between the rolls 15 and 16 so as to be slidable. The application of this is not limited to this.

As shown in FIG. 8, the width of each block 30, 31, 32 in the front-rear direction is substantially the same as the width of the seats 15 a, 16 a in the front-rear direction, and each block 30, 31, 3 2 may be arranged above the rolls 15 and 16 so as to be able to move up and down. In this case, the connection of the connecting members 5 and the folding of the sheets 15a and 16a are performed by pressing from above the blocks 30, 31 and 32. Also, in this case, the force that requires a large block according to the width of each sheet 15a and 16a in the front-rear direction ^{: The} sheet becomes wrinkled because it is not necessary to slide each block. Hateful.

Next, a method of manufacturing the blind member 2 will be described.

The raw sheet supply rolls 102, 103 are attached to the support portions 105, 106 of the apparatus main body 101, respectively. The sheet of each roll 102.103 is fed by a conveying device 111,112,115,116 and a bonding device 113,114. At the time of this conveyance, the folds are formed on the sheets 102 a and 103 a by the fold forming devices 109 and 110. That is, the sheets 102 a, 103 a are sandwiched between the support blocks 120, 122 of each fold forming apparatus 109, 110 and the pressing members 122, 123. A concave fold and a convex fold are alternately formed on each of the sheets 102a and 103a. The folded sheets 10 2 a and 10 3 a are respectively conveyed to the bonding devices 1 13 and 1 14 by the conveying devices 111 and 112.

On the other hand, the connection member 5 is supplied from the connection member supply unit 104 in synchronization with the conveyance of the sheets 102a and 103a. Note that a thermoplastic adhesive is applied to the entire surface of the connecting member 5 on the surface to be bonded to each sheet. The distal end of the connecting member 5 is gripped by the hand 144 c of the hand mechanism 144, and is cut to a predetermined length by the cutting device 144. Next, the hand mechanism 144 is rotated 90 °, and the cut connecting member 5 is sent to the first bonding apparatus 113 side. Here, one end of the connecting member 5 (corresponding to the folded portion 5a in FIG. 2) is guided on the upper surface of the block 125, and comes into contact with the sheet 102a. Then, the heating and pressing members 126 are pressed from above and heated. As described above, since the surface of the connecting member 5 is coated with a thermoplastic adhesive, the portion in contact with the heating and pressing members 126 is melted by heating, and the folded portion of the connecting member 5 is heated. 5a will adhere to sheet 102a. Since the block 125 rotates, the rotation causes the sheet 102 a to be transported inside the apparatus main body 101.

The sheet 102 a to which the one folded portion 5 a of the connecting member 5 is bonded is conveyed to the second bonding device 114, where the other folded portion 5 a of the connecting member 5 becomes the sheet 103 a Adhered to. The operation at the time of bonding is the same as in the case of the first bonding device 113. As a result, the pair of sheets 102 a and 103 a is connected to each other by the connecting member 5 as shown in FIG. The blind member 2 is further transported further downward by the second bonding device 114 and the transport device 116, and cut at a desired position by the cutting device 135.

In such a manufacturing apparatus 100, while continuously conveying the sheets 102a and 103a, forming a fold, cutting the connecting member 5, and bonding the connecting member 5 to the sheet are performed. It is possible to adapt to mass production. In addition, in this manufacturing apparatus 100, since the connecting member 5 is transported while being bonded to the sheets 102a and 103a by the bonding apparatuses 113 and 114, the apparatus is connected. Can be configured as In addition, by changing the interval between the concave portions of the fold forming devices 109 and 110 and the length of one side of the block 125 of the bonding devices 113 and 114, the interval between the folds of the blind member 2 can be easily made. Can be changed to Furthermore, if the shape of the concave portion of the fold forming device 109, 110 and the shape of the tip of the pressing member 122, 223 are, for example, curved surfaces, the fold can be rounded in the same manner as the device described above. It can give the entire blind a sense of volume and softness.

(Modified example)

FIG. 12 shows a modification of the embodiment shown in FIG.

In this example, the raw sheet roll 103, its transport system (including guide rollers 108, transport devices 112, etc.) and the fold forming device 110 are connected to the connecting member supply unit 104. It is located above. In this case, although the dimension in the height direction is increased, the occupied floor space of the device is reduced, and the space can be reduced. In addition, all the supply sections for the sheets and the connecting members are arranged on the right side in FIG. 12 and the left side is the discharge section, so that the work in the factory can be easily performed.

Other embodiments

The accordion force 50 has an accordion member 51. The accordion member 51 has substantially the same configuration as the blind member 2 (FIG. 2), and the points at which the folds of the respective shield members constituting the accordion member 51 are arranged in the vertical direction and the hanging string 1 are provided. The difference is that 0 is omitted. A side cap 52 is attached to one end of the accordion ion member 51. Above the accordion member 51, a guide rail 53 for guiding the movement of the accordion member 51 is provided. Brackets 54 are fixed to both ends of the guide rail 53. The guide rail 53 is attached to, for example, a window frame wall by the bracket 5.

Also in this case, each of the shielding members constituting the accordion member 51 is one sheet. Since each member is composed of continuous members, painting and patterning as shown in Fig. 13 can be easily performed by using, for example, a patterned fabric, and the design can be improved. In use, a tensile load in the left-right direction acts on the accordion member 51 via the guide rail 52, but this tensile load acts on each shielding member itself constituting the accordion member 51. Thereby, the tensile strength can be improved. The accordion member 51 is also manufactured using the same apparatus as the above-described manufacturing apparatus.

(b) In the above-described blind 1 and accordion curtain 50, as shown in FIG. 14, a heat insulating material 60 may be inserted into a space surrounded by the shielding members and the connecting members. By inserting the heat insulating material 60, the heat insulating effect of the blind member 2 and the acoustic curtain 50 is improved. In addition, it can be applied not only to blinds and accordion curtains, but also to a wide range of uses such as partitions. Various changes can be made without departing from the present invention. The foregoing description of the best mode of the present invention has been presented for purposes of illustration and description only, and is not intended to limit the invention, which is defined by the scope of the claims and its equivalents, to those disclosed. There is no intention.
