Description

Roll-blind manufacturing device {Manufacturing device for roll-blind}

The present invention relates to a blind manufacturing apparatus that integrates cutting, winding, and connecting strip attaching processes for manufacturing a roll blind, particularly a large roll blind.

The roll blind refers to a blind having a function of shielding a window or the like in such a way that the blind fabric is wound or unwound in a cylindrical shape on the outer circumferential surface of the rotatable roller. In particular, in recent apartments and offices, the use of combination blinds that take into account the ventilation of wind while selectively blocking sunlight as the fabric part and the mesh part are woven alternately is increasing.

In other words, when the blind screen is installed double and the fabric part and the mesh part overlap in a zigzag manner, the sun blocking and blackout function is strengthened, and when each part overlaps at the same time, the ventilation function through the mesh part is strengthened. Compared to the existing blind method, the length of the blind fabric is doubled, and the height and width between floors are increasing in line with the recent trend of luxury apartments.

Under such circumstances, blinds tend to be enlarged, and a wide working space is required to cut the blind fabric to a predetermined length.

1 is an apparatus for cutting a conventional roll blind fabric. As shown in Figure 1, when the blind fabric is supplied to the work bench 210 through the fabric feeder, the main body 200 provided with a processing hole 212 on one side of the work bench, and the lower circular blade 314 rotated by motor power. With this attached fabric cutter 300, the blind fabric is cut in the width direction of the fabric, the blind fabric cut in the width direction is spread again on the work table, rotated in the up and down direction to fit the fabric in the longitudinal direction, and then the fabric in the predetermined longitudinal direction. Cutting is performed using a cutter, and then, a connecting strip is attached to the fabric and inserted into the winding rod, and the winding rod is manually wound and cut with a roll blind.

However, in the process of cutting the blind fabric using a conventional circular blade, it is easy to cut the blind supplied to the fabric feeder in the width direction, but for cutting in the longitudinal direction, the blind fabric must be widely spread and rotated and then adjusted to the cutter. It requires a workbench of a size suitable for the width and length of the blind, and in particular, a cutting workbench of at least 4Mx4M is required in line with the recent double blind method and the trend of larger size.

Moreover, in the case of a blade cutting the fabric, the circular blade used is a compression cutting method using pneumatic pressure, and there is a problem that the side of the cut fabric is not constant. A problem is occurring.

In addition, in the case of a circular blade, the unit price is high, and the replacement period is required more than once a month. It takes at least 30 minutes to unscrew and assemble, which is a factor that lowers work productivity.

In addition, for the cut blind fabric, select a large, medium, and small size connecting strip and winding rod suitable for the size and thickness of the fabric, attach a connecting strip to the bottom of the blind, insert it into the winding rod, and manually wind the blind to complete the blind. In this process, there is a problem of inefficiency of work through manual work and non-uniform winding of the fabric.

As shown in FIG. 2 , a cutter assembly 430 including a cutter 431 , a pressing member 433 , and a holder for screwing the cutter is formed on a plurality of rails to perform cutting of the fabric.

However, this type of fabric cutting device requires a complicated process of pressing the roller on which the fabric is wound to the bottom to cut the fabric and pressing the pressure bar formed at the most end of the frame to contact the roller and the cutter assembly, and the cutter blade As it protrudes toward the direction of the worker, there is a risk of safety accidents during work.

In addition, since the cutter blade is fixed to the holder through a screw, it is time-consuming and cumbersome to replace it due to wear of the blade, and only the process for cutting the fabric is described thereafter. and the process of continuously performing the winding operation with the winding rod is not disclosed.

3 is another prior art, the present applicant's prior art roll blind manufacturing apparatus is disclosed. As shown in Figure 3, it is composed of a cutting base portion 81 composed of a rotating body with a blade mounted thereon, an elastic return member, and a handle member. It is placed on the outside of the fabric and the fabric is cut while the winding roll rotates, and when the handle is released after cutting is finished, the rotating body is spaced apart from the winding roll by the restoring force of the elastic return member and the blade is spaced apart.

However, in this method, the blade is always loaded, so a situation occurs in which the handle part is pressed by the operator's movement or mistake during work. there is a problem that

In addition, although the mounting blade is detachable, it causes trouble when replacing it because it is a method of unscrewing the screw for firewood.

Therefore, the present invention solves the problems of the prior art as described above in the process of manufacturing the roll blind, minimizes the working space, and efficiently cuts the blind fabric in the width and length directions while inserting the winding rod to make the blind It is to provide a roll blind manufacturing apparatus that collectively performs a series of work processes for winding the.

At this time, when the user inputs the desired fabric length to the control unit 20, the measuring roller 31 of the length measuring unit 30 rotates to measure the fabric length, and the length to which the feed length of the fabric 71 is input. When reaching , the control unit 20 receiving the measured value by the sensor unit 35 of the length measuring unit 30 stops the operation of the first motor unit 50, so that the rotation of the winding roll 64 is also stopped. do.

Thereafter, after cutting in the width direction of the original paper 71 that has been transferred to the take-up roll 64 up to a predetermined length of the fabric, one end of the original paper 71 is fixed with a tape. The transverse cutting of the original paper 71 may be performed manually using scissors, or may be automatically performed using an automatic cutting device.

The guide frame 40 is provided with a scale part 41 for measuring the size of the fabric, and the base member 101 is moved left and right by a predetermined length of the fabric to adjust the size.

At this time, when the required cutting length of the fabric is input to the display unit of the control unit and the base member is moved left and right automatically or manually, the guide member connected to the base member and the scale display unit 46 move.

The scale display part 46 is positioned as much as the actual fabric length excluding the necessary dimensions such as the closing cap of the roll bar from the width direction length of the entire required fabric, and the cutter holding bar 109 of the cutting winding part is positioned corresponding to this position. Therefore, cutting is performed by inserting a cutter in an ideal state.

After the cutter is mounted, the first motor 50 is operated by the control signal of the controller 20 to rotate the winding roll 64 . At the same time, the cutter blade 400 of the cutter 110 is in contact with the original paper 71 of the winding roll 64 rotating at the same time, and the cutter blade penetrates into the original fabric by rotation to cut the fabric.

At this time, since the cutter is supported and fixed between the base member and the rotating support, neat cutting is performed without shaking of the cutter.

The cut-out fabric 71 is attached by drawing a connecting band, which is a plastic strip, from the connecting band bundle of the connecting band supply member at the end, for example, the slit 124 of the large-sized roll bar 120 . It is inserted into the mounting groove 122 through.

Sequentially, insert up to the engaging projection 104 so that the mounting groove 122 of the roll bar 120 into which the connecting strip is inserted is seated on the coupling protrusion 106 of the rotation support 102, and insert it into the rotation support 102. , Similarly, the other end of the roll bar 120 is also inserted into the rotation support part of the other side. At this time, in the case of using the small size roll bar 121, it is inserted into the small size rotation support unit 103 through the same process.

Then, when the second motor 10 connected to one side of the base member in which the rotation support part is formed in the cutting winding part formed on the left end side of the roll blind manufacturing apparatus through the operation of the control unit 20 is operated, the driving force of the motor is cut As the rotation support part is transmitted to the rotation support part of the winding part and the rotation support part fitted with the roll bar is rotated, the fabric 71 wound on the take-up roll 64 is wound on the roll bar. Since it is wound as it is released from the coil, an appropriate tension is applied to wind it and it is tightly wound on the roll bar.

As a follow-up operation, the roll blinds are manufactured by assembling the accessories of the roll blinds.
