  In the devices of Patent Document 1 and Patent Document 2 described above, the rope is pressed by rollers on the four sides of the joinery, and is press-fitted into the fixed groove with the net interposed therebetween. Thus, smooth pressing was performed over the four sides of the joinery by rolling the roller onto the rope.

However, in these devices, since the roller for press-fitting the rope is circular and the radius thereof is larger than the depth of the fixed groove, the end of the fixed groove (the start end of the press-fitting side and the end of the press-fitting side) An area that cannot be pushed by the roller is generated at the end. As a result, there is a problem that the rope cannot be sufficiently press-fitted into the fixed groove at the start and end of the fixed groove.
In Patent Document 1, a member (bead restraint) for pressing the rope is provided separately from the roller. This rope holding member is effective in preventing the rope from lifting when the roller is changed because it only pushes the rope at a point, but it contributes to the secure press-fitting of the rope at the start and end of the fixed groove. is not.

The main purpose of the present invention is to provide a screen door production equipment that rope can be reliably press-fitted in beginning and end of the fixing groove.
Another object of the present invention is to press-fitting ropes continuously on the four sides of the joinery, automating the rope cut, automating the size change of the joinery, automating the net pulling and cutting, preventing deformation of the joinery due to the net tension, and to provide a capable screen door production equipment prevent misalignment.

The screen door manufacturing apparatus of the present invention is a screen door manufacturing apparatus for fixing the net to the joinery by press-fitting a rope into the fixing grooves formed on the four sides of the frame-shaped joinery, and fixing the net to the joinery. A pushing roller capable of pushing the rope into an intermediate portion of the groove; a pushing block capable of inserting the rope at a starting end and a terminal end of the fixing groove; and surfaces of the fitting on both sides of the pressing groove on both sides of the fixing groove. And a pair of rope guides for pressing the net between them.

In the present invention, the pushing roller can continuously push the rope at the intermediate portion of the fixed groove. Furthermore, the push block which can be inserted into the start and end of the fixed groove can push the rope into the start and end of the fixed groove. At this time, the pushing block can be formed into an arbitrary shape that can be pushed to the end of the fixed groove and the end of the fixed groove, and insufficient push of the rope at the end of the fixed groove can be avoided.
Therefore, according to the screen door manufacturing apparatus of the present invention, the rope can be reliably press-fitted even at the start and end of the fixed groove.
Moreover, when the pushing block press-fits the rope into the fixed groove, the rope can be guided from both sides, and the press-fitting operation of the rope at the start end and the end of the fixed groove can be performed more reliably.

  In the screen door manufacturing apparatus of the present invention, the screen door manufacturing apparatus includes a table on which the joinery is placed, a joinery holding mechanism for holding the joinery placed on the table, and the net on the upper surface side of the joinery. A net feeding mechanism for feeding, and a rope insertion mechanism for pushing the rope into the fixed groove from the upper surface side of the net, the rope insertion mechanism, the rope feeding mechanism for feeding the rope, and the rope feeding A rope pushing head that press-fits the rope from a mechanism into the fixing groove of the joinery placed on the table, and a moving mechanism that moves the rope pushing head, the rope pushing head, A pressing roller unit that supports the pressing roller so as to be movable up and down; and a pressing block unit that supports the pressing block so as to be movable up and down. Desirable.

In the present invention, the above-described push roller and push block of the present invention can be equipped as a push head. The joinery holding mechanism holds the joinery on the table. A net supply mechanism supplies a net. A rope insertion mechanism press-fits the rope and fixes the net to the joinery.
At this time, in the rope insertion mechanism, while the rope is supplied from the rope supply mechanism, the rope pushing head is moved along the fixing groove of the joinery by the moving mechanism, so that the rope continues to the fixing groove extending over the entire circumference of the joinery. Can be press-fitted.

Therefore, the rope can be press-fitted continuously on the four sides of the joinery by the rope pushing head and the moving mechanism.
The rope cutting can be automated by providing a rope cutter in the rope pushing head.
Furthermore, by providing the joinery holding mechanism with a size adjustment function, a drawer function, and a net cutter, it is possible to automate the size change of the joinery, and to automate the net drawing and cutting.

In the screen door manufacturing apparatus according to the present invention, it is preferable that the rope pushing head has an auxiliary block that pushes the net adjacent to the pushing block.
In the present invention as described above, the tension of the net can be adjusted by the following operation. First, it is set as the state by which one side was fixed to the fixing groove among a pair of edge which the net | network fixed to joinery opposes. In this state, in order to fix the net on the other side, an operation of pressing the rope into the fixing groove is performed. In this operation, the auxiliary block adjacent to the push-in block for press-fitting presses the net in the portion along the inside of the joinery, and temporarily tightens the net.

That is, the net tension is increased by pressing the net with the auxiliary block against the tension applied to hold the net along the joinery before the rope is pushed. At this time, the pressing by the auxiliary block is desirably performed at a portion of the net held along the joinery as close as possible to the joinery, that is, a portion along the inside of the joinery. Can be effectively enhanced.
In this way, with the net tension temporarily strengthened, the adjacent pushing block presses the rope into the fixing groove and fixes the other side of the net. As a result, the net is fixed between the pair of edges. Here, when the auxiliary block is retracted, the temporary tension applied to the net is also released, and the tension of the net between the pair of edges is tensioned with a looser tension.

Therefore, the auxiliary block of the present invention can relieve the tension of the net. Accordingly, it is possible to prevent the deformation of the joinery due to the tension of the net and the misalignment of the net.
Furthermore, in the present invention, the net can be adjusted at the start and end of the fixed groove where the auxiliary block is adjacent to the push block and the press-fitting by the push block is performed. At this time, the auxiliary block presses the net in a state where it does not move with respect to the net at the start end and the end of the fixed groove.For example, when the pressing roller continuously presses the rope at the intermediate portion of the fixed groove, There is no difficulty of moving relative to the net while pressing the net. And an auxiliary block and a pushing block can be collectively installed in a rope insertion mechanism, and it is suitable also for simplification of an apparatus structure.

According to the screen door manufacturing apparatus and the screen door manufacturing method of the present invention, the pushing roller can continuously push the rope at the intermediate portion of the fixed groove, and the push block can reach the end of the fixed groove at the start and end. Pushing of the rope can be performed reliably.
Further, according to the screen door manufacturing apparatus and screen door manufacturing method of the present invention, it is possible to press the rope continuously on the four sides of the joinery, automate the rope cut, automate the size change of the joinery, automate the net drawing and cut, and the net tension. It is possible to prevent the deformation of the joinery and the misalignment of the net.

  In such a unit 72, the rope 5 is guided by the pair of rope guides 721 so that the rope 5 fits in the fixed groove 4 before the rope 5 is press-fitted into the fixed groove 4 by the push-in block 711 (see FIG. 8). be able to. That is, when the pair of rope guides 721 is positioned at the lower limit position, the rope 5 is disposed between the respective 721s. Thereby, the rope 5 is positioned so as to be located immediately below the pushing block 711.

  Further, when the rope 5 is press-fitted into the fixed groove 4 by the pushing block 711, the rope guide unit 72 uses the elasticity of the coil spring of the support mechanism 722 to press-fit the net 3 into the fixed groove 4. Can be pressed against the upper surface of the joinery 2. Thereby, it is possible to prevent the net 3 from being wrinkled.

  Here, since the support mechanism 722 elastically supports the pair of rope guides 721, the amount of movement in the vertical direction can be changed for each rope guide 721. That is, the pair of rope guides 721 can be displaced according to the step and press the net 3 even when there is a step on the upper surface of the fitting 2 with the fixed groove 4 as a boundary (see FIG. 7).

The auxiliary block unit 73 is disposed adjacent to the side of the rope guide unit 72 (see FIGS. 6 to 8). The auxiliary block unit 73 includes an auxiliary block 731 and an auxiliary block lifting cylinder 732.
The auxiliary block 731 is a plate-like member arranged horizontally.
The auxiliary block elevating cylinder 732 is a device for elevating the auxiliary block 731 and is supported by a bracket fixed to the side of the third base 55.

In the auxiliary block 731, the other side portion opposite to the one side portion is fixed by the pushing block 711 in the state where one side portion of the edge of the net 3 fixed to the fitting 2 is already fixed to the fixing groove 4. When fixed to the groove 4, the net 3 is pressed against the table 10 together with the pressing of the net 3 by the rope guide 721 (see FIGS. 7 and 8).
Thereby, the auxiliary block 731 can adjust the tension of the net 3.

The push roller unit 74 includes a push roller 741 and a push roller lifting cylinder 742. The pushing roller unit 74 supports the pushing roller 741 so as to be movable up and down.
The pushing roller 741 is a disk having a thickness that can be inserted into the fixing groove 4 of the joinery 2, is disposed on the rear side on the extension line of the pushing block 711, and can rotate around a rotation axis that intersects the pushing block 711. .
The push roller lifting cylinder 742 is a device that lifts and lowers the push roller 741, and is installed on the lower surface of the third base 55.

The rope cutter unit 75 has a pair of rope cutters 751 and a rope cutter drive cylinder 752.
The rope cutter 751 is a member having blades at opposite ends of each other, and the rope 5 can be cut by approaching each other.
The rope cutter driving cylinder 752 moves the pair of rope cutters 751 to a position approaching and a position separating from each other.

As described above, the rope pushing head 70 of the present embodiment reliably press-fits the rope 5 supplied from the rope supply mechanism 60 into the end portion of the fixed groove 4 of the fitting 2 by the pushing block unit 71. Can do.
At this time, the net presser unit 72 can smoothly guide the rope 5 and the net 3 into the fixed groove 4 by appropriately guiding the rope 5 and pressing the net 3 around the fixed groove 4.

Further, the auxiliary block unit 73 can adjust the tension of the net 3.
The pushing roller unit 74 can continuously press-fit the rope 5 and the net 3 into the intermediate portion of the fixed groove 4 after the rope 5 and the net 3 are press-fit into the end of the fixed groove 4.
The rope cutter unit 75 can cut the rope 5 after the rope 5 is press-fitted into the fixing groove 4 on the entire circumference of the joinery 2.

The control device 90 controls the operation of the moving mechanism 50, the rope supply mechanism 60 and the rope pushing head 70 by executing a program stored in advance, and presses the rope 5 into the fixed groove 4 on the entire circumference of the joinery 2. Then, the net 3 is fixed to the joinery 2.
In FIG. 1, the control device 90 can be housed inside an equipment case installed at the bottom of the table 10. The control device 90 may be connected to an existing control panel or a portable computer system for the operator to operate.

The operation in this embodiment is as follows.
First, as shown in FIG. 1, the joinery 2 is placed on the table 10. At this time, the joinery 2 is held on the upper surface of the table 11 of the table 10. And the net | network 3 is supplied to the upper surface of the mounting base 11, and is arrange | positioned so that the upper surface of the fitting 2 may be covered. Next, as shown in FIG. 10, the rope pushing head 70 moves so as to go around the entire circumference of the joinery 2 (four sides of the first side E1 to the fourth side E4), and enters the fixing groove 4 of each side E1 to E4. The rope 5 and the net 3 are press-fitted respectively. Thereby, the screen door in which the net 3 is fixed to the joinery 2 is manufactured.

In FIG. 11, when starting the manufacturing procedure, the worker carries the joinery 2 into the table 10, causes the control device 90 to read the joinery type from the barcode of the joinery 2, and starts a series of processes (process S1). .
The control device 90 controls the joinery holding mechanism 20 and adjusts the positions of the first movable side holder 23 and the 224 according to the dimensions and specifications of the joinery 2. Thereby, the joinery 2 is clamped by the first fixed side holder 21, the second fixed side holder 22, the first movable side holder 23, and the second position 224, and is held at the reference position (processing S2).

The control device 90 activates the net supply mechanism 30 after the joinery 2 is held. The net supply mechanism 30 pulls out the net 3 on the joinery 2, cuts the net 3 with a required length, and clamps the net 3 along the four sides of the joinery 2 (Process S3).
At this stage, the joinery 2 and the net 3 are in the state shown in FIG. That is, the joinery 2 is placed on the table 10 and held by the joinery holding mechanism 20. Further, the net 3 is pulled out above the joinery 2 by the net supply mechanism 30 and is clamped along the four sides of the joinery 2.
In this state, the rope pushing head 70 is placed at the standby position of the table 10 (near the fourth edge E14).

The control device 90 activates the rope insertion mechanism 40 after the joinery 2 and the net 3 are arranged on the table 10. The rope insertion mechanism 40 starts the operation of press-fitting the rope 5 into the fixing grooves 4 on the four sides of the fitting 2.
Prior to the execution of the rope press-fitting operation, the control device 90 activates the moving mechanism 50. The moving mechanism 50 moves the rope pushing head 70 (moving MA in FIG. 10). Thereby, the rope pushing head 70 is introduced from the standby position to the press-fitting operation region above the joinery 2 (processing S4 in FIG. 11).

Subsequently, the control device 90 rotates the rope pushing head 70 along the first side E1 to the fourth side E4 of the fitting 2. At this time, the rope pushing head 70 sequentially executes a rope press-fitting operation on the first side E1 to the fourth side E4 of the joinery 2.
That is, the processes S11 to S14 illustrated in FIG. 11 are performed on the first side E1 of the joinery 2. Next, processes S21 to S24 shown in FIG. 11 are performed on the second side E2 of the joinery 2. Next, processes S31 to S34 shown in FIG. 11 are performed on the third side E3 of the joinery 2. Next, processing S41 to S44 illustrated in FIG. 11 is performed on the fourth side E4 of the joinery 2.

Here, as shown in FIG. 10, the rope pushing head 70 divides each side En (n = 1 to 4) into a start end portion, an intermediate portion, and a termination portion in the rope press-fitting operation of each side E1 to E4. In each case, the start push Pnt, the continuous push Mn, and the end push Pne are performed.
Among these, the pushing block unit 71 (the pushing block 711) is used for the start pushing Pnt and the termination pushing Pne. For the continuous pushing Mn at the intermediate portion, the pushing roller unit 74 (the pushing roller 741) is used.

Further, the rope pushing head 70 is connected to the end pushing Pne of the previous side En-1 and the next pushing so that the end pushing operation by the pushing block unit 71 can be continuously performed at the corners C1 to C4 where the sides intersect. The start end push Pnt of the side En is made a series of operations, and the push block unit 71 is changed in direction during the push operation of each end. That is, the rope pushing head 70 rotates so that the pushing block unit 71 is displaced from the position above the side En-1 to the position above the side En-1.
Therefore, the rope press-fitting operation is started from the end push P4e at the end of the fourth side E4 of the joinery 2.

That is, in FIG. 11, the rope press-fitting operation with respect to the first side E1 is performed by changing the direction at the corner C1 (processing S12) following the end pushing P4e (processing S11) of the fourth side E4. After performing the start end pushing (processing S13), the middle portion of the first side E1 is continuously pushed (processing S14).
When the rope pushing head 70 reaches the end of the first side E1, the rope pushing head 70 performs a rope press-fitting operation on the second side E2, which is the next side.

The rope pushing head 70 repeatedly executes the rope press-fitting operation with the second side E2 (processing S21 to S24), the third side E3 (processing S31 to S34), and the fourth side E4 (processing S41 to S44).
In addition, when the last process S44 is complete | finished, the rope pushing head 70 will go around the fitting 2 and will return to the terminal of the 4th edge | side E4.

  The rope press-fitting operation at each of the sides E1 to E4 described above is common. The detailed procedure of the rope press-fitting operation repeated at each side is as shown in FIG.

As shown in FIG. 12, the rope press-fitting operation of the side En includes the end pushing P (n-1) e of the previous side (processing S51 to S56), the direction change Tn at the corner Cn (processing S57), and the side En It is performed in the order of the start end push Pnt (processes S61 to S66) and the continuous push Mn (processes S67 to S60) in the middle of the side En.
As an example, in the rope press-fitting operation on the first side E1, the following procedure is executed.

First, the rope pushing head 70 performs the end pushing P4e (processing S51 to S56) of the fourth side E4.
The control device 90 arranges the rope pushing head 70 at the end position of the fourth side E4 (processing S51).
Thereby, the rope pushing head 70 is moved to the corner C1 of the joinery 2 (see FIG. 10, the intersection of the first side E1 and the fourth side E4). And the rope pushing head 70 is arrange | positioned in the terminal part of the 4th edge | side E4, and is made into the state (state which turned the intermediate part and start end part of the 4th edge | side E4 back) toward the opposite side to the corner C4. .

  Here, the control device 90 checks the side En currently being processed (processing S52). Then, if the side currently being processed is the third side E3 and the fourth side E4, the control device 90 moves down (step S53) and moves up (step S54) the auxiliary block 731. Here, since the process for the first side E1 is in progress, the process directly proceeds to the process S55.

Next, the control device 90 operates the pushing block unit 71 to lower the pushing block 711 (Process S55).
Thereby, as shown with a dashed-dotted line in FIG. 13 and FIG. 14, the edge part of the rope 5 and the net | network 3 are press-fit in the termination | terminus position of the fixing groove 4 of the 4th edge | side E4.
Thereafter, the control device 90 raises the pushing block 711 and returns it to the original position (processing S56).
Thus, the end push P4e of the fourth side E4 is completed.

Next, the rope pushing head 70 performs the direction change T1 (processing S57) at the corner C1.
The control device 90 turns the rope pushing head 70 in the T1 direction shown in FIG. 14 to place the pushing block 711 at the start end position of the first side E1 (processing S57).
As a result, the pushing block 711 is brought into a state indicated by a solid line in FIGS. In addition, even if it turns, the rear end of the pushing block 711 is maintained at the same position.
Thus, the direction change T1 at the corner C1 is completed.

Next, the rope pushing head 70 performs the start end pushing P1t (processing S61 to S66) of the first side E1.
The control device 90 arranges the rope pushing head 70 at the start end position of the first side E1 (processing S61). Since the rope pushing head 70 is disposed at the start position of the first side E1 by the direction change T1, the control device 90 only needs to confirm the position.

  Here, the control device 90 checks the side En currently being processed (processing S62). Then, if the side currently being processed is the third side E3 and the fourth side E4, the control device 90 lowers (step S63) and rises (step S64) the auxiliary block 731. Here, since the process for the first side E1 is in progress, the process directly proceeds to the process S65.

Next, the control device 90 operates the pushing block unit 71 to lower the pushing block 711 (Process S65).
Accordingly, as shown in FIGS. 15 and 16, the rope 5 continuous from the end of the fixing groove 4 on the fourth side E4 is press-fitted into the starting end position of the fixing groove 4 on the first side E1.
Subsequently, the control device 90 operates the pushing block unit 71 to raise the pushing block 711 and return it to the original position (processing S66). Thereby, the pushing by the pushing block 711 is cancelled | released.
Thus, the start end pushing P1t of the first side E1 is completed.

Next, the rope pushing head 70 performs continuous pushing M1 (processing S67 to S60) of the first side E1.
The control device 90 operates the push roller unit 74 and lowers the push roller 741 while moving the rope push head 70 toward the terminal end side of the first side E1 (Process S67).
As a result, the rope 5 press-fitted into the starting end position of the fixed groove 4 on the first side E1 is pushed into the fixed groove 4 by the push roller 741, as indicated by a one-dot chain line in FIG.

Next, the control device 90 further moves the rope pushing head 70 and moves the pushing roller 741 along the fixed groove 4 on the first side E1 (processing S68).
Thereby, the rope 5 and the net 3 are continuously press-fitted into the fixed groove 4 at the intermediate portion of the first side E1 by the pushing roller 741.
Then, when the push roller 741 reaches the vicinity of the end of the first side E1, the control device 90 stops the movement of the rope push head 70 (Process S69).
Subsequently, the control device 90 operates the push roller unit 74 to raise the push roller 741 and return it to the original position (processing S60). As a result, the pushing by the pushing roller 741 is released.
Thus, the continuous pushing M1 of the first side E1 is completed.

The rope press-fitting operation of the first side E1 is completed by the above-described start end pressing P1t (processing S61 to S66) and continuous pressing M1 (processing S67 to S60).
Note that the end push P1e (steps S51 to S56) for press-fitting the rope 5 to the end of the first side E1 is executed continuously with the start end push P2t (steps S61 to S66) of the next second side E2 rope press-fitting operation. Is done.
That is, as shown in FIGS. 18 and 19, the control device 90 stops the movement of the rope pushing head 70 when the pushing roller 741 reaches the vicinity of the end of the first side E1. Then, the control device 90 raises the pushing roller 741, and the pushing block 711 is lowered again so that the rope 5 is pushed into the end position of the fixed groove 4 on the first side E1.

The above is the procedure of the rope press-fitting operation with respect to the first side E1.
The rope pushing head 70 performs the same process on the second side E2, the third side E3, and the fourth side E4.
At this time, for the third side E3 and the fourth side E4, a branching process for net tension adjustment is performed in the end pushing process S52 and the starting push process S62. That is, in parallel with the pushing of the rope 5 by the pushing block 711, the pressing of the net 3 by the auxiliary block 731 (processing S53 to S54, processing S63 to S64) is performed.

In FIG. 7, the rope 5 and the net 3 are pushed into the fixed groove 4 by the pushing block 711. At this time, the net 3 is sandwiched between the rope 5 and the bottom surface of the fixed groove 4. At this time, the net 3 is pressed by the auxiliary block 731 at the inner part around the fitting 2.
Specifically, the auxiliary block 731 presses a portion that approaches the third side E3 or the fourth side E4 on the inner peripheral edge of the fitting 2. Thereby, the auxiliary block 731 temporarily strengthens the tension of the net 3. Then, the net 3 is bent by the pressed amount, and the portion sandwiched by the fixing groove 4 is shifted to the inner peripheral edge side around the fitting 2.

  After the rope 5 and the net 3 are pushed in, the auxiliary block 731 moves away from the net 3 in order to release the pressure on the net 3. After the pressing by the auxiliary block 731 is released, the net 3 is in a state of being loosely stretched on the joinery 2. For this reason, it can avoid that the fitting 2 is distorted by the excessive tension | tensile_strength of the net | network 3 (what is called a drum state).

Note that these processes are performed only on the third side E3 and the fourth side E4 in which fixing of the opposing sides (the first side E1 and the second side E2) is completed.
That is, when the pushing block 711 pushes the rope 5 and the net 3 into the fixing groove 4 on the third side E3, the auxiliary block 731 pushes the net 3 at a portion close to the third side E3. Further, when the pushing block 711 pushes the rope 5 and the net 3 into the fourth side E4 fixing groove 4, the auxiliary block 731 pushes the net 3 at a portion close to the fourth side E4.
Even if the auxiliary block 731 presses the net 3 in a state where the opposite side and the net 3 are not fixed in the press-fitting operation of the rope 5 with respect to the first side E1 and the second side E2, the net This is because the tension is not adjusted only by shifting 3.

As described above, when all the press-fitting operations of the rope 5 with respect to the first side E1 to the fourth side E4 (the process of FIG. 12) are completed, the control device 90 executes a predetermined end process.
The control device 90 activates the rope cutter unit 75. The rope cutter unit 75 cuts the rope 5 continuous from the rope pushing head 70 to the joinery 2 (processing S5).
Subsequently, the control device 90 activates the moving mechanism 50. The moving mechanism 50 retracts the rope pushing head 70 located at the end of the fourth side E4 to the aforementioned retracted position (process S6, moving MR in FIG. 10).

Thus, the automatic execution by the control device 90 is completed.
The operator takes out the joinery 2 to which the net 3 is fixed from the table 10 (processing S7).
Thereby, the production for one screen door is completed (processing S8).

Further, in the present embodiment, the rope 5 can be pushed into the fixed groove 4 by the push block 711 at the start and end of the fixed groove 4. At this time, the push-in block 711 can push the rope 5 to the start end and the end of the end of the fixed groove 4, and can avoid insufficient push of the rope 5 into the fixed groove 4.
Therefore, according to this embodiment, the rope 5 can be reliably press-fitted even at the start and end of the fixed groove 4.

  In the present embodiment, since the pair of rope guides 721 are provided on both sides of the push block 711, the rope 5 can be guided from both sides when the rope 5 is press-fitted into the fixed groove 4 by the push block 711. Therefore, in this embodiment, the press-fitting operation of the rope 5 at the start end and the end end of the fixed groove 4 can be performed more reliably.

In the present embodiment, the pushing roller 741, the pushing block 711, the rope guide 721, and the like described above can be collectively provided as the rope pushing head 70.
