Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a screen-screening apparatus for setting a insect-proof net on a screen-door frame. The present invention relates to a screen-screening device that can be fixed without loosening or deforming the screen-door frame. 2. Description of the Related Art A screen door is formed by extruding an insect-resistant net made of, for example, a polyvinyl chloride resin on a frame made of, for example, an extruded aluminum alloy material. Usually, the insect screen is put on the screen door frame, and a rubber net holding rope is pushed together with the net into a net receiving groove formed along the inner peripheral portion of the frame. [0003] However, conventionally,
Such screen-screening work of the screen door is performed by hand, and there is no deformation of the screen frame due to excessive tension of the screen, and considerable skill is required to stretch the screen so that the screen is not loose. This was a time-consuming task. [0004] That is, simply press-fitting the insect repelling net together with the net holding rope into the net receiving groove of the net door frame causes the net frame F to be deformed by the tension of the net N as shown in FIG. If such deformation occurs, as shown in FIG. 9B, a gap S is generated between abutting portions of screen doors or a sash vertical frame, and the insect repellent function is impaired. become. Further, for example, when the support rod is inserted between the frames of the screen door frame F to forcibly expand the center part of the frame and the screen holding rope and the insect repelling net are pressed into the screen receiving groove, the screen door frame is used. Although the deformation of F falls within the allowable dimensions, there is a problem that slack occurs near the center of the frame of the insect repellent net and the appearance as a screen door is impaired. A challenge in screen manufacturing has been the development of a screen screen meshing device that can secure the insect screen to the frame without causing slack or deformation of the screen frame in time. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in the conventional screen manufacturing process, and does not require a high level of skill when meshing screens.

Next, together with the rope guide 16 of the first rope press-in device 6, the press-in roller 17 with the wire holding rope R wound thereon as shown in FIG.
As shown in FIG. 5D, the net holding rope R is pressed into the net receiving grooves G of the vertical frames F1 and F2 together with the insect net N, and the starting end of the net holding rope R is released from the rope winding mechanism 18. At the same time, the rope winding mechanism 18 rotates backward in the traveling direction of the screen door frame F. At this time, the adjustment bar 14b, which is a tension adjusting member, is interposed between the insect net N and the screen door frame F, so that the insect net N is given an appropriate bend. The end portion is balanced with the length dimension to be drawn into the net receiving groove G of the frame material together with the net holding rope R so that the net door frame F is not deformed. FIG. 1A shows a situation where the insect-preventing net N is pressed into the net receiving groove G of the screen door frame F. The central part of the insect-preventing net N is specified by the adjusting bar 14b. In the state of being lifted to the height, both edges are pressed into the net receiving groove G together with the net holding rope R by the press-in rollers 17, 17. When the insect repellent net N is pressed into the net receiving groove G, as shown in FIGS. 1A and 1B, the insect repelling net N is inserted into the net receiving groove G by a length substantially equal to the circumference of the net holding rope R. The insect repellent net N is adjusted to a previously determined height position such that the insect repellent net N is supplied extra between the vertical frames F1 and F2 of the frame F by a length corresponding to the retracted length. Since the center portion is lifted by the bar 14b, the tension of the insect repellent net N becomes excessive and the vertical frame F1,
F2 is deformed, and the size of the insect repellent net N is
It is larger than the dimension between 1 and F2, so that the insect repellent net does not become loose. When the tip of the insect repelling net N is fixed to the screen frame F, the arm 22 of the net mounting mechanism 12 is raised by the retracting operation of the cylinder 20. Next, the screen door frame F moves together with the insect repelling net N by the operation of the first work carrier 3b, and accordingly, as shown in FIG. The removal of the surplus portion proceeds. When the screen door frame F moves and the insect repellent net N having a length corresponding to the size of the frame F is drawn out, the net cutting mechanism 13 operates to cut the insect repellent net N. By moving the screen frame F, the vertical frame F

After the insect screen N and the net holding rope R have been pressed into the net receiving groove G of F2, the screen door frame F is transferred by the second conveyor 4a in a direction parallel to the horizontal frames F3 and F4. When the screen door frame F reaches a predetermined position, the vertical frame F2 of the screen door frame F is clamped by the clamper 4d of the second work carrier 4b, and the screen holding rope R is pressed into the vertical frames F1 and F2. In exactly the same manner as above, the second rope press-fitting device 7 is used to
Pressing of the net holding rope R into the net receiving groove G of F4 is started, and press-fitting of the net holding rope R and fusing of the insect repellent net N by the heat cutter progress as in FIG. Removed. When the press-fitting of the net holding rope R into the net receiving grooves G of the horizontal frames F3 and F4 is completed, the rope guide of the second rope press-in device 7 similarly rises, and the screen door frame F is connected to the corner processing device 9 by It reaches the portal frame 8,8. The corner-holding jig 23b is pushed down by the operation of the cylinder 23a of the corner holding mechanism 23 of the corner processing device 9, and the start end and the end of the net holding rope R floating from the net receiving groove G are insect-proof. Each of them is pressed into the net receiving groove G together with the net N. Next, by moving the slide base 8a, the corner cutter 24 of the corner processing device 9 is positioned inside the corner of the screen door frame F, and as shown in FIGS. 8B to 8D,
After the heat cutter 24e is lowered by the pushing operation of the cylinders 24c and 24d, the heat cutter 24e is pushed out toward the corner portion of the insect repellent net N, and the insect repellent net N is provided by the heat cutter provided in the first and second rope press-fitting devices 6 and 7.
The uncut corners are blown. At this time, since the heat from the heat cutter 24e is blocked by the heat insulating material 24f, there is no thermal influence on the insect repellent net N, and deterioration of the material of the insect repellent net N can be prevented. The removal of the surplus portion of the insect repellent net N by the heat cutter 24e and the heat cutter 19 is performed by thermal fusing, so that there is no breakage and no yarn residue is generated, so that a screen door with good appearance quality can be obtained. become. The screen door completed as described above is transferred to the unloading side of the apparatus by the third conveyor 4c, and is transferred to the next step, for example, the inspection step. In the above-described embodiment, an example has been shown in which, at the time of press-fitting of the insect-controlling net N, the substantially central portion of the insect-controlling net N is lifted to a predetermined height by the adjusting bar 14b as a tension adjusting member. Conversely, it is also possible to bend the insect-controlling net N by pushing down the insect-controlling net N and balance it with the length dimension drawn into the net receiving groove G. As described above, in the screen door tying apparatus according to the present invention, the tension adjusting member for lifting or pushing down the central portion of the insect repelling net to a predetermined position, the net holding rope and the insect repelling net are provided. Press-fitting means for press-fitting into the screen receiving groove of the screen door frame.When the screen of the screen door is to be meshed, the edge of the insect screen is lifted to a predetermined position or pushed down to a predetermined position. Since it is made to press-fit into the net receiving groove of the screen door frame together with the net holding rope, extra insect repelling net can be supplied between the frames by the amount corresponding to the size of the insect net that enters with the net holding rope into the net receiving groove. The size of the insect repellent net when the edge of the insect repellent net is inserted into the net receiving groove matches the dimension between the frames of the screen door frame, preventing deformation of the screen door frame and loosening of the net. It is possible to stop the insect repellent net without any loosening or deformation of the frame.
