Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a wall hanging manufacturing apparatus that cuts threads into short lengths and plants them on a mesh-like base fabric. In particular, the present invention relates to an apparatus capable of manufacturing a wall hanging by planting threads in a pattern similar to an image inputted from an image reading means.

[Conventional technology]

Wall hangings, which are made by cutting threads of different colors and densities into fixed lengths and planting them on a base fabric to display paintings and designs, have a unique aesthetic and can beautifully decorate a room. This wall hanging can be made by planting thread on the base fabric using a hook gun. That is, it can be manufactured by fixing the outer periphery of the base fabric to a frame and stretching it flat, holding a hook gun in your hand, and planting threads of different colors and densities on the base fabric. This device prints a pattern on the base fabric to make it easier to see where the threads are planted.

[Problem to be solved by the invention]

With this structure, the hook gun is held in the hand and the yarn is planted on the base fabric, so wall hangings with various patterns can be manufactured. However, this device has the drawback that the more complicated the design, the more time and effort it takes to manufacture a single wall hanging, and the manufacturing cost increases significantly. In addition, since the threads are actually planted by hand, it is difficult to produce wall hangings with very complex designs. A carpet manufacturing apparatus has been developed in which the movement of a hook gun in a horizontal plane, the control of a trigger, and the vertical movement are controlled by an NC device (Japanese Patent Publication No. 1-33585). This manufacturing device uses an NC device to automate the movement of the hook gun and the control of the trigger, which were previously performed manually. This device can automatically plant yarn instead of manually. However, since this device merely automates the operation of a conventional hook gun, it has the disadvantage that yarn cannot be implanted with a clear resolution that exceeds the capability of a conventional hook gun. The reason is that conventional hook guns adjust the planting of thread by controlling the rotation of the motor on and off, which prevents the thread from being planted accurately in a narrow area. That is, since the amount of yarn planted is adjusted by adjusting the time when a switch, which is a trigger, is turned on, the yarn cannot be planted accurately in an extremely narrow area. Furthermore, with hook guns that control the rotation of the drive motor with a trigger, it takes time for the motor to rotate at a constant speed after the switch is turned on, and the motor rotates a certain amount due to inertia after the switch is turned off. Since the threads are then planted, it is difficult to accurately plant the threads in a small area, resulting in uneven planting areas. Furthermore, the conventional hook gun cannot bend a single cut thread into a U-shape and plant it on the base fabric, as shown in FIG. That is, as shown in FIG. 2, the conventional device has a structure in which the minimum planting amount is at least 1.5 threads on the base fabric. This is because the hook gun is equipped with a cutter that cuts the thread at the tip of the needle. The resolution of the resulting pattern is different depending on whether the minimum number of threads to be planted is three, as shown in FIG. 2, or two threads, as shown in FIG. Furthermore, conventional hook guns have the disadvantage that the thread planting speed cannot be changed. The reason for this is that the rotational speed of the motor that drives the hook gun and plants the yarn cannot be controlled. For this reason, there was a drawback that the thread density could not be controlled by moving the hook gun at a constant speed in a horizontal plane. That is, there was a drawback that it was not possible to densely plant the threads in an extremely narrow area or to make the density of the threads coarse. By the way, wall hangings require extremely high resolution compared to carpets. This is because it is smaller than a carpet and requires a clear pattern. In order to increase the resolution of the wall hanging pattern and clearly express various colors, it is necessary to reduce the minimum number of plants to be planted, accurately control the number of plants, and partially control the density of the threads. What you can do is required. For wall hangings, the middle part of the thread that has been bent and planted is glued to the back of the base fabric, so as shown in Figure 1, the minimum unit is one thread that can be bent and planted. becomes. Furthermore, as shown in FIG. 2, the threads planted in a straight line without being U-bent have the disadvantage that they tend to move before the back side is fixed with adhesive. In addition, in the manufacturing process, there is a drawback that the upper and lower positions in the diagram tend to be misaligned. For this reason, after the threads are planted, it is necessary to cut the protruding parts of the threads on the back and front surfaces of the base fabric so that the heights of the threads are on the same plane. If the threads protrude from the back side of the base fabric, unevenness will be created on the lining fabric that is adhered to the backside, and if the threads protrude from the front side, the surface of the wall hanging will be uneven. The wall hanging manufacturing device of this invention is capable of manufacturing one thread by U 1111
This invention was developed for the purpose of efficiently manufacturing wall hangings with clear patterns of various designs that can be planted accurately. To provide a wall hanging manufacturing device capable of manufacturing wall hangings and efficiently mass producing them at low cost.

Controller 5 controls the rotation angle of the gun drive servo motor. (2) The gun drive servo motor 7 drives the thread planting machine 4, and the thread planting machine 4 plants the threads on the base fabric B. The gun drive servo motor 7 is angularly controlled by the controller 5, so that it accurately implants the yarn by a predetermined amount.

The wall-mounted manufacturing apparatus shown in FIGS. 3 to 9 includes a manual image reading means 1, and an operation that performs arithmetic processing on the image read by the reading means 1 and decomposes it into a plurality of points of different colors or different densities. means 2, a storage means 3 for storing the processing results of the calculation means 2, a thread transplanter 4 controlled by the image signal stored in the memory means 3, and a moving position and attitude of the thread transplanter 4 and a planting machine.

It is equipped with a servo motor 7. As the reading means 1, an image scanner can be used. An image scanner can read an image and separate it into points with different colors and densities. However, as the reading means 1, a digitizer, mouse, keyboard, television camera, etc. can be used. A microcomputer can be used as the calculation means 2. The images inputted from these reading means 1 are processed by the calculation means 2.
This decomposes it into points, and further converts the color and density of the points into digital signals. The image processed by being separated into points by the calculation means 2 is stored in the storage means 3. As the storage means 3, a floppy disk, a hard disk, an optical disk, a RAM, etc. can be used. The thread transplanter 4 includes a cylindrical needle 8, a yarn delivery member 9, a cutter 10, an air supply member that supplies pressurized air to the cylindrical needle 8,
It is equipped with a thread A delivery member 9. The tube needle 8 is set on the base of the thread transplanter 4 so as to be movable up and down. The cylindrical needle 8 has a cylindrical shape so that the thread A can be passed through it in the axial direction of the center. The lower end of the cylindrical needle 8 is beveled so that it can be smoothly inserted into the stitches of the base fabric B. As shown in FIG. 7, when the beveled needle 8 is moved horizontally, the beveled surface is positioned on the back side. The air supply member includes an air flow tube 11 for drawing the yarn into the tube needle 8. The air flow cylinder 11 is disposed in a straight line above the cylinder needle 8 so that the thread A can be guided linearly with respect to the cylinder @8. The air flow cylinder 11 has a structure that injects air into the interior and pulls the thread A with the air flow. That is, the air flow cylinder 11 is provided with a thread hole 12 passing through the center in the i+d+ direction, and an air hole 13 is opened extending through the center in the radial direction and connected to the thread hole 12. The air hole 13 is arranged in the sending direction of the yarn Δ (
The air is injected downward (in Fig. 4). Therefore, the air hole 13 is opened at an angle so that the tip thereof faces downward, which is the feeding direction of the yarn A. Air hole 1
The air flow injected from 3 to the thread hole 2 flows in the direction of pulling the thread A, and the air flow pulls the thread A and guides it to the side 8. The air pressure supplied to the air holes 13 determines the pulling force on the yarn. If the air pressure is weak, the yarn A will not be sucked into the thread hole 12 of the air flow tube 11 with a sufficiently strong force, and the cut end of the yarn A will not be reliably sucked into the tube needle. Therefore, the air pressure supplied to the air hole 13 is usually 5 to 1
2kg/cm2, preferably 7-10kg/cm2
Adjusted to a range of 2. Although not shown, the air supply member includes an on-off valve and a compressor, and the air pressurized by the compressor is supplied to the air flow cylinder 11 through the on-off valve. The on-off valve is opened and closed in synchronization with the vertical movement of the barrel needle, and is closed when the cutter 10 cuts the thread A, that is, when the barrel needle 8 is raised, and is opened at other positions. Above the cylinder needle and below the air flow cylinder 11 is a cutter 10.
is installed. The cutter 10 cuts the yarn in synchronization with the vertical movement of the cylindrical needle 8. As shown in FIG. 6, the cutter 10 cuts the thread A when the tube needle 8 inserts the thread A into the base fabric B and ascends. The cutter 10 may include a rotary blade that comes into contact with the lower surface of the air flow tube 11 and rotates in a horizontal plane to cut the yarn. The sending unit 9 adjusts the sending amount to the thread by jl'J2.
rollers 35 are provided. The rollers 35 pinch the yarn A and send it out. The roller 35 rotates while holding the yarn A therebetween, and adjusts the amount of yarn A to be sent out based on the radius. One roller 35 is connected to a drive shaft of a gun drive servo motor via a gear (not shown). The diameter of the roller on the side driven by the gun drive servo motor is
Determine the length of the thread to be planted on the base fabric. If the roller is large, the threads planted on the base fabric will be long, and if the roller is small, the threads will be shortened. Although not shown, the roller driven by the gun drive servo motor is set to be replaceable. Adjust the size of the roller and apply the base fabric B.
Adjust the length of thread A to be planted in. A thread guide (not shown) is provided in the path of the thread A to guide the thread A to the rollers. The thread planting machine 4 shown in FIGS. 5 to 9 has the following steps:
Thread A is planted on base fabric B. The gun drive servo motor 7 drives the vertical movement of the barrel needle 8, the rotation of the cutter 10, and the rotation of the roller 35, which is a delivery member, in synchronization with each other. FIG. 10 shows a schematic diagram of the thread planting machine 4 and the gun drive servo motor 7 that drives it. Thread planting machine 4 shown in this figure
a crank 29 connected to the drive shaft 28 of the gun drive servo motor 7 via a bevel gear with a gear ratio of 1:1;
A reciprocating table 31 connected to this crank 29 via a connecting rod 30, and a drive shaft 28 of a gun drive servo motor,
Cutter 1 connected via a gear with a gear ratio of 1=1
0. The reciprocating table 31 is mounted on the base of the thread planting machine so as to be vertically movable. When the crank 29 is rotated once, the reciprocating table 31
It is reciprocated once up and down. On the carriage 31, in order from the bottom, a cylinder needle 8 and a cutter 1 are installed.
0 and an air flow cylinder 11 are attached. Cutter 1
0 is rotatably mounted on a carriage 31. The cutter 10 is a rotary blade that rotates to cut the thread, and is fixed to the lower end of a vertically supported rotary shaft 32. The upper end of a rotating shaft 32 that rotates the cutter 10 is connected to the gun drive servo motor 7 via a gear. The rotating shaft 32 is expanded and contracted when the carriage 31 is moved downward by one inch. Therefore, the rotating shaft 32 is
3, and a spline shaft 34 inserted through the drive cylinder 33. The spline shaft 34 is inserted into the lower end of the drive cylinder 33 so as to be able to move in and out in the axial direction, but not to rotate relative to each other. That is, the inner surface of the drive cylinder 33 is provided with protrusions and grooves that engage with the outer surface of the spline shaft 34. The gun drive servo motor 7 has a crank 29 and a cutter 1.
0 and rotates at the same number of rotations. The position where the cutter 10 cuts the thread is adjusted to the position where the crank 29 moves the carriage 31 to the top. For this reason, the cutter 10 cuts the thread every time the carriage 31 moves to the second most position. The gun drive servo motor makes one reciprocation up and down the carriage 31,
Moreover, each time the cutter 10 rotates once, the tube needle 8 plants the thread cut into a predetermined length in a U-bend on the base fabric. Therefore, each time the drive shaft 28 of the gun drive servo motor 7 makes one revolution, one thread cut to a predetermined length is planted in a U-bend on the base fabric. FIG. 11 shows a cylinder needle 8 driven by a gun drive servo motor.
It is a graph showing the vertical movement of the cutter 10, the operation of the cutter 10, and the air injection state of the air flow cylinder. As shown in this figure, the cylinder needle 8 is reciprocated up and down by a crank 29. When the tube needle 8 moves to the top, the cutter 10 slides on the lower end of the air flow tube and cuts the thread. At this time, the on-off valve of the air flow cylinder is closed and the air injection is temporarily stopped. The wall-mounted manufacturing device of this invention controls the rotation angle of the gun drive servo motor. For this reason, after completing the thread planting,
The stop position of the gun drive servo motor can be specified. The gun drive servo motor 7 stops the two-down movement of the carriage 31, the rotation of the cutter 10, and the rotation of the delivery member 9 at predetermined positions after the yarn is planted on the base fabric on the side 8. The position where the gun drive servo motor stops the carriage 31 and the cutter 10 is set immediately before the cutter 10 cuts the thread, in other words, just before the carriage 31 rises to the highest stage. The stop position of the gun drive servo motor 7 is controlled by the controller 5. The controller 5 controls the rotation angle of the gun drive servo motor 7 to specify the stop position. The wall-mounted manufacturing equipment of this structure is used in the following conditions. The base fabric on which the yarn is to be planted is fixed to a base frame (not shown) by pulling the outer periphery with a predetermined tension. If the tension of the base fabric is weak, the cylinder needle will not be able to reliably penetrate the base fabric. Therefore, the base fabric is pulled with sufficient tension and fixed horizontally below the thread transplanter so that the needle can pass through the thread reliably. (2) As shown in FIG. 5, lower the cylindrical needle 8 and make the tip penetrate the base fabric B. At this time, the cylindrical needle 8 is lowered with the thread inside. The delivery unit 9 is driven by the gun drive servo motor 7,
The yarn is sent out by rotating the gun drive servo motor 7. (2) As shown in FIG. 6, the cylindrical needle 8 moves while the air supply member supplies air. Therefore, the part side 8 rises, leaving the thread A penetrated through the base fabric B. When the tube needle 8 rises, the cutter 10 is moved out of the lower end of the air flow tube 11 and does not cut the thread. (2) When the cylinder needle 8 rises to the vicinity of the uppermost part, the air flow cylinder 11 temporarily stops supplying air, and the cutter 10 slides on the lower end of the air flow cylinder 11 to cut the yarn A. ■ As shown in FIG. 7, the thread planting machine 4 is moved by a predetermined amount. (2) As shown in FIG. 8, the cylindrical needle 8 descends again and penetrates the base fabric B. When the cylinder needle 8 is lowered, the air flow cylinder 11
injects pressurized air to guide the thread Δ to the tube needle 8. ■ As shown in Figure 9, when the barrel needle 8 descends to the bottom,
The cut thread A is inserted into the base fabric B in a U-shaped manner. ■ Thereafter, the steps from ■ to ■ are repeated, and the thread planting machine 4 plants the threads on the base fabric B. By the way, after being moved to the planting position of the base fabric B, the yarn seeding machine 4 plants the yarn in the predetermined position of the base fabric I (in steps 1 to 2). With the gun drive servo motor 7,
It is driven in the state of Gun drive servo motor 7 is controlled by controller 5. The controller 5 controls the gun drive servo motor 7 and the position/posture drive means 6 to move the yarn planting machine 4 to a predetermined position on the base fabric B, and sow the yarn Δ onto the base fabric B. After the yarn planting machine 4 is moved to the next planting position one after another,
The gun drive servo motor 7 is driven to plant the yarn A on the base fabric B. When the yarn planting machine 4 is moved, it is raised by the Z-axis drive member 15, moved to a predetermined position by the XY drive member 14 in the raised state, and then lowered by the Z-axis drive member 15 to place the base fabric B. Plant thread A on. The controller 5 drives a position/posture drive means 6 and a gun drive servo motor 7. The position and orientation driving means 6 is
It includes an XY drive member 14 that moves the thread transplanter 4 in a horizontal plane, and a Z-axis drive member 15 that moves the thread transplanter 4 in the upper and lower Z-axes. FIG. 3 shows the XY drive unit 14 and the Z-axis drive member 15. The XY drive member 14 and Z-axis drive member 15 shown here include a threaded rod 17, a motor 18 for rotating the threaded rod 17, and a nut 19. The XY drive member 14 includes a vertically moving table 20 and a horizontally moving table 21. The vertical movement table 20 includes a slide 23 that moves along guide rods 22 fixed in parallel to both sides of the base fabric B. Threaded rod 1 along guide rod 22
A nut 19 screwed into the threaded rod 17 is fixed to a vertically movable table 20. When the threaded rod 17 is rotated by the motor 18, the vertical moving table 20 is rotated by the guide rod 2.
2 in the Y-axis direction. The horizontal movement table 21 is slidably attached to the guide rod 24 of the vertical movement table 20. The vertical moving table 20 has a guide rod 2
A threaded rod 17 is attached parallel to 4. Threaded rod 1
A nut 19 screwed into 7 is fixed to a lateral movement table 21. When the threaded rod 17 is rotated by the motor 18,
The lateral movement table 21 moves along the guide rod 24 in the X-axis direction. The Z-axis drive member 15 includes a vertical guide 25, a vertical table 26 movably set on the vertical guide 25, a threaded rod 17, and a motor 18. The vertical guide 25 extends upward from the horizontal movement table 21,
Fixed vertically. A threaded rod 17 is attached parallel to the vertical guide 25. The vertical table 26 is set on a vertical guide 25 so as to be vertically slidable, and a nut 19 screwed into a threaded rod 17 is fixed thereto. When the threaded rod 17 is rotated by the motor 18, the up-and-down table 26 is moved up and down along the vertical guide 25, that is, in the Z-axis direction. A rotational drive member 16 is attached to the upper and lower stands 26 . The rotational drive member 16 rotates the thread transplanter 4 in a horizontal plane. The rotational drive member 16 includes a gear 27 to which the thread transplanter 4 is fixed, rotatably supported on a horizontal plane by an upper and lower table 26, and a geared motor 18 that rotates the gear 27. When the motor 18 rotates the gear 27, the thread transplanter 4 is rotated in a horizontal plane. The controller 5 controls the gun drive servo motor 7 and the position/posture drive means 6 to move the thread planting machine 4 to a predetermined position, and the thread planting machine 4 plants the yarn A on the base fabric B. Therefore, the controller 5 includes the motor 18 of the XY drive member 14 and the motor 18 of the Z-axis drive unit +, 115.
The rotation of the thread transplanter 4 is controlled to move the thread transplanter 4 to a predetermined position on the base fabric B. Further, the controller 5 controls the rotation of the motor 18 of the rotational drive member 16 to control the attitude of the thread transplanter 4. As shown in FIG. 7, the posture of the thread transplanter 4 is such that when the tube needle 8 moves in a horizontal plane, the oblique cut surface of the lower end of the tube needle 8 faces rearward in the direction of movement. The controller 5 converts the signals stored in the storage means 3 into
The yarn transplanter 4 is moved by inputting it from the calculation means 2 or by directly inputting a signal stored in the storage means 3 (not shown) to control the position/posture driving means 6 and the gun drive servo motor 7. Then, plant thread A. The controller 5 controls the rotation angle of the gun drive servo motor 7. Therefore, the thread density of the base fabric can be adjusted by controlling the rotational speed of the gun drive servo motor. The thread planting density can be adjusted by changing the rotational speed of the gun drive servo motor while moving the thread transplanter as an XY drive member at a constant speed. If the rotational speed of the gun drive servo motor is increased while the XY drive member moves the yarn implanter at a constant speed, the yarn implantation density can be increased. On the other hand, if the rotational speed of the gun drive servo motor is slowed down while the thread planting machine is moved at a constant speed, the thread planting density can be lowered. Controller 5 includes a gun drive servo motor and an XY
Controls the rotation angle of the servo motor of the drive member. By controlling the rotation angles of both the XY drive member servo motor and the gun drive servo motor, yarn can be planted in ideal conditions. For example, the yarn planting density can be adjusted by controlling the ratio of the rotational angular velocity of the XY drive member servo motor to the rotational angular velocity of the gun drive servo motor. The thread planting machine 4 of the present invention plants threads A of different colors or densities on a base fabric B to produce a wall hanging with a pattern of an image manually inputted from the reading means 1. Therefore, 1
Using the actual thread A, plant it in a predetermined position on the base fabric B with the thread planting machine 4 (after planting, replace the thread, and then repeat the operation of planting the thread Δ). A wall hanging is manufactured by planting and felling a plurality of yarns A. [Effects of the Invention] The wall hanging manufacturing apparatus of the present invention uses a yarn planting machine to U-bend a single yarn cut to a predetermined length. In other words, by setting the minimum number of threads that can be planted to one, the resolution of color and density can be increased, and various complex patterns can be expressed with beautiful colors and density to create high-class wall hangings. The thread planting machine has an air flow tube between the upper end of the section side and the feeding section, and this air flow tube pulls the cut yarn into the tube needle. This is because it can be inserted through the base fabric.Furthermore, in the wall-hanging manufacturing device of the present invention, the thread planting machine is driven by a can drive servo motor whose rotation angle is controlled by a controller.In other words, the device of the present invention Unlike conventional hook guns, the thread-planting state is not controlled by controlling the rotation of the drive motor.For this reason, the wall-mounted manufacturing device of the present invention is designed to control the vertical movement position of the tube needle and the cutter. By accurately controlling the cutting position of
It has the advantage of being able to accurately place yarn in a specific area. Therefore, the apparatus of the present invention has the advantage of being able to mass-produce extremely high-resolution wall hangings at low cost. Furthermore, as shown in FIG. 1, the apparatus for manufacturing the wall-shaped fabric of the present invention can plant the yarn in a U-bend manner on the back side of the base fabric. The threads planted in this state are securely fixed to the base fabric. Therefore, the manufacturing apparatus of the present invention has the advantage of being able to accurately plant the threads in fixed positions on the base fabric. Therefore, the effort required to cut and align the threads protruding from the back surface of the base fabric can be reduced, and the number of threads protruding from the front surface of the base fabric can also be reduced. In addition, the wall hanging manufacturing apparatus of the present invention reads a photograph or painting with an image scanner or the like, or reads an actual image with a television camera, divides it into density or color with a calculation means, and uses this as the basis dμ. Since patterns are created by planting a plurality of threads of different colors or densities on the wall hangings, wall hangings with various patterns can be easily and efficiently produced.
