  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a state in which the sewn product moving apparatus of the present invention is attached to a sewing machine. In the drawing, the sewing machine M1 is composed of an upper structure and a lower structure, the upper structure is a sewing arm M1a for sewing a sewing product, and the lower structure is a sewing bed M1b for fixing the sewing product. The sewn product moving device 10 translates and rotates the sewn product during sewing of the sewing machine. The sewing product moving apparatus 10 is installed between the sewing machine arm M1a and the sewing machine bed M1b.

  FIG. 2 is a perspective view showing a state in which the sewing product moving apparatus 10 is not installed on the sewing machine M1. The sewing machine M1 shown in this figure does not rotate the sewing product, but only carries it in the X and Y directions, and the coordinates of the clamp device 101 for holding the sewing product are shown by the conveyance device 102 having a conveyance motor. This is a device that can be automatically sewed with a desired sewing pattern by conveying it in the X direction and the Y direction and moving it relative to the sewing needle 103.

  The sewing machine arm M1a includes a sewing needle 103, a needle bar 104 that holds the sewing needle 103 and moves it up and down in the Z direction, a presser device 105 that prevents the cloth from being lifted by pulling a thread during sewing, and a sewing needle 103. And a balance mechanism 106 that pulls up the upper thread that has been passed through.

  The sewing machine bed M1b is passed through a clamping device 101 that holds a sewing product, a conveyance device 102 that conveys the sewing product to an arbitrary position in the X direction and the Y direction, a sliding plate 107 that is a sewing processing plane, and a sewing needle 103. A hook 108 that entangles the upper thread with the lower thread.

  As described above, the clamp device 101 of FIG. 2 can be replaced with the sewing product moving device 10 of FIG.

  FIG. 3 is a perspective view showing a detailed structure of the sewn product moving apparatus 10 according to the first embodiment. In the figure, a sewing product moving device 10 is installed in a frame member 31 that is translated by a conveying motor of a conveying device 102 provided in the sewing machine M1, and is rotatably installed on the frame member 31. And a mounting table 32 on which an object is mounted.

  Further, a separate drive device 40 is provided so that the relative position with respect to the sewing machine does not change even when the frame member 31 and the mounting table 32 are translated by driving the transport motor of the transport device 102. Further, a transmission means 20 </ b> A for transmitting the driving force of the driving device 40 to the mounting table 32 to rotate the mounting table 32 is provided.

  The transmission means 20A includes a first rail 22a connected to at least a part of the mounting table 32, a second rail 22b disposed at a position perpendicular to or twisted from the first rail 22a, and a second rail A connecting portion 22c that slidably connects the first rail 22a to the rail 22b.

  Furthermore, it has the 1st pulley 24 and the arm-shaped base (grip part) 21 which connects the 2nd rail 22b to this 1st pulley 24. As shown in FIG.

  One or both of the connecting portion 22c and the arm-shaped base 21 slidably connect the second rail 22b, and are suspended by the first pulley 24 to rotate the first pulley 24. Have a belt.

  A first pulley 24 is fixed on the arm-shaped base 21. Further, the first rail 22 a is fixed to the mounting table 32. Alternatively, it may be formed integrally with the mounting table 32.

  The attachment of the frame member 31 to the sewing machine is completed by removing the clamping device 101 of FIG. 2 and fixing the position indicated by A in FIG. 3 of the frame member 31 to the conveying device 102 of FIG. 2 with screws.

  The drive device 40 of the sewn product moving apparatus 10 includes a drive motor 41 and a second pulley 42 that is connected to or directly connected to the rotation shaft of the drive motor 41 and suspends a belt to transmit a driving force. The second pulley 42 is connected to the first pulley 24 via the belt 25 of the transmission means 20 </ b> A, and the power of the drive motor 41 is transmitted to the first pulley 24.

  The first pulley 24 of the transmission means 20A and the second pulley 42 of the driving device 40 are configured to be driven via the belt 25. However, instead of the belt 25, the first pulley 24 is driven by a chain. Alternatively, a configuration in which power is transmitted using gears is also possible. The drive motor 41 here is a stepping motor. The motor cable used in the driving device 40 is connected to a control panel (not shown) from the side surface of the sewing machine arm M1a through the sewing machine bed M1b.

  In the rotation of the sewing product moving device 10, the arm-shaped base 21 is driven by the drive motor of the driving device 40, and the arm-shaped base 21 is connected via the first rail 22a, the second rail 22b, and the connecting portion 22c. Thus, the driving force is transmitted to the mounting table 32 so that the mounting table 32 can rotate.

  Since the driving device 40 is arranged independently of the frame member 31 and the mounting table 32, the weight of the driving device 40 is equal to the load of the conveying motor when the sewing product is translated by the conveying motor of the conveying device 102. In addition, high-speed and high-precision conveyance is possible.

  The transmission means 20A to the sewing machine and the drive device 40 are attached to the support frame 20a indicated by the two-dot chain line in the drawing on a mounting base (not shown) for a flat plate-like extension device provided in advance on the sewing machine arm M1a. The transmission means 20A and the driving device 40 are fixed to the mounting base for the extension device, and the process is completed. This mounting base is provided on the surface of the sewing machine arm M1a facing the sewing machine bed M1b. Alternatively, it may be integrated with the sewing machine arm M1a. The transmission means 20A and the driving device 40 may be attached to any position of the sewing machine as long as they do not interfere with the operation. The shape of the support frame 20a can be changed according to the mounting position, or may not be installed.

  FIG. 4 is a perspective view showing the transmission means 20A and the driving device 40 of the first embodiment. The first pulley 24 is fixed to the arm-shaped base 21 by means such as screws, and a second rail 22b (not shown) installed on the arm-shaped base 21 sandwiches the rotation center of the first pulley 24. It is slidable and gripped. The 2nd rail 22b is connected with the arm-shaped base 21 via the block 22d provided with a bearing.

  Further, the transmission means 20 </ b> A of the sewing product moving apparatus 10 has a base plate 23. The base plate 23 is a fixing plate for the first pulley 24, the driving device 40, and the support frame 20a, and can be attached to the sewing machine arm M1a by integrating the transmission means 20A and the driving device 40.

  Further, the transmission means 20A can be attached with a sensor for detecting the origin position and a detection plate as a detected body.

  FIG. 5 shows a cross-sectional view of the sewn product moving apparatus 10 between BB in FIG. As shown in the figure, the first pulley 24 is held by a cylindrical shaft 44 via a bearing 43. A space is provided in the cylindrical shaft 44 so as not to hinder the movement of the needle bar 104, the presser device 105, and a sewing thread (not shown).

  If the workpiece W (sewn product) in the figure has a size that does not fit within the mounting table 32, the workpiece W (sewing product) contacts the guide roller 31a, the guide roller holder 31b, and the frame member 31 that fix the outer ring 32a of the mounting table 32, and is sewn. May be an obstacle. By installing the workpiece support 33 on the mounting table 32, it is possible to prevent the workpiece W from rotating in a suspended state, and to solve the above-described problems.

  A total of two sets of first rails 22a are attached to the mounting table 32 in parallel with each other. The transmission means 20A is connected to the mounting table 32 via the first rail 22a, the second rail 22b, and the connecting portion 22c, and transmits the driving force of the driving device 40 to the mounting table 32 for rotation.

  Although the first rail 22a and the second rail 22b are arranged so as to be orthogonal to each other in the first embodiment, there is no obstacle even if they are arranged so as to cross each other diagonally, and the first rail 22a. Is composed of two parallel rails, but the number is not limited to this and may be one or any other number.

  FIG. 6 is an exploded perspective view of the sewn product moving apparatus 10. The frame member 31 fixes the guide roller 31a having a groove and a bearing to the guide roller holder 31b with a pin 31c so that the mounting table 32 can be smoothly rotated while holding the outer ring 32a of the mounting table 32. Place around the circumference. A plurality of guide rollers 31a are arranged. When the guide rollers 31a are attached, the center of rotation of the mounting table 32 can be kept constant by finely adjusting the guide roller holder 31b, and the Z direction is perpendicular to the processing plane of the sewing product. This prevents the mounting table 32 from being displaced.

  The mounting table 32 includes a presser frame 34 that holds the placed sewing product (sewing material such as cloth and leather), and an opening S that is arranged in the presser frame 34 and corresponds to a target sewing pattern. In addition, the presser frame 34 and the opening S are provided in the base plate 32 b of the mounting table 32.

  The presser frame 34 can be opened and closed by a hinge 35a, and a magnet 35b is disposed on the back surface of the presser frame 34 so that the sewing product can be held by a magnetic force. In addition to the method of using the magnet 35b, the method of holding the sewing product may be a holding means using a toggle clamp or spring repulsion. In addition, if the sewn product processing space including the holding method is separated from the base plate 32b and is detachable from the base plate 32b, it is possible to flexibly cope with changes in the sewn product and the sewing pattern.

  FIG. 7 is a view for explaining a method for attaching and detaching the sewing product W to the mounting table 32. By transporting the frame member 31 in the X direction and rotating the arm-shaped base 21 of the transmission means 20A in a direction that does not hinder the replacement of the sewing product W, the presser frame 34 can be opened and closed, and the sewing product W can be easily attached and detached. It is possible to

  FIG. 8 is a top view schematically representing rotation of the sewing product moving apparatus 10 according to the first embodiment of the present invention. In the figure, the point C is the center of the sewing needle 103 and is the same as the rotation center of the transmission means 20A, and the point O is the rotation center of the frame member 31 connected to the conveying device 102 (not shown). The state in which the point C and the point O coincide with each other in FIG. 8A is set as a standby state, and from this point, the point C moves to the point S in FIG. 8B, and the point S is centered in FIG. It is a figure which rotates the mounting base 90 degree counterclockwise.

  In FIG. 8B, the transport device 102 transports the frame member 31 to a location where the point C, which is the center of the sewing needle 103, and the point S on the mounting table 32 coincide. Since the transmission means 20A and the mounting table 32 are connected by the first rail 22a and the second rail 22b arranged so as to cross each other, when the frame member 31 moves in parallel on the XY plane, It is possible to make the relative position free.

  Next, the operation when the mounting table 32 is rotated 90 degrees counterclockwise around the point S from the state of FIG. 8B to obtain the state of FIG. 8C will be described. The point S, which is the current position, is a state in which the sewing needle 103 is temporarily stopped with the sewing needle 103 stuck in the sewing product and is being lifted and lowered for the next sewing. If the point C, which is the center of the sewing needle 103, and the point O, which is the rotation center of the mounting table 32, are the same, the frame member 31 remains stopped at the current position, and the transmission means 20A rotates alone by 90 degrees. Then, the rotation operation of the sewing product for the next sewing is completed.

  However, when the point C and the point O are not the same, the point S on the mounting table 32 where the sewing needle 103 is stuck moves with respect to the sewing needle 103, and the needle breaks, the needle is bent, and the processing by the needle is performed. Holes are widened and sewing thread is supplied more than necessary, so that the sewing quality is significantly reduced.

  In order to solve this, as shown in FIG. 8C, while the drive device 40 performs the motion of rotating the point C counterclockwise by 90 degrees with the distance r between the point C and the point O as the rotation radius, The conveying device 102 may move the frame member 31 in parallel so that the point O extends along the arc R up to the point O1. In the sewn product moving device 10 of the present invention as well, the sewn product can be rotated indefinitely with the center of the sewing needle 103 and the point where the sewing needle 103 is stuck coincident at any position on the XY plane by the above-described method. It is possible to make it.

  In the first embodiment, by using the transmission means 20A for the sewing product moving device 10, it is possible to smoothly move the mounting table 32 by driving of the driving device 40 and to carry it with high accuracy. It is possible to sew by other methods shown in FIG.

  FIG. 9A to FIG. 9D show a process in which an arc pattern is sewn. In the figure, the center of the arc pattern S coincides with the rotation center O of the mounting table 32. In this state, the frame member 31 holds the state stopped on the Y axis in the figure, and the transmission means 20A rotates counterclockwise, so that the rotation center O of the mounting table 32 and the center C of the sewing needle 103 are obtained. It is possible to sew arcs with a radius of the distance between and perfect stitches. However, it should be noted that if the number of stitches is small, the pattern becomes close to a polygon and the stitch formation direction may be outside the θPS region in FIG.

  It is also possible to sew a linear pattern with perfect stitching by applying the sewing method of the arc pattern, and it is conveyed so that the stitch formation direction is a straight line along the X direction during sewing by rotating the sewing product or workpiece. This is realized by performing correction in the Y direction of the apparatus 102.

  In the first embodiment, since the driving device 40 is installed on the sewing machine independently of the conveying device 102, rotation with respect to the sewing needle 103 and conveyance on the processing plane of the sewing product can be made independent during sewing. It is only necessary to drive the mounting table 32 via the transmission means 20A with only the device 40, and efficient sewing is possible.

  The sewn product moving device 10 of the present invention is attached with the center of rotation of the arm-shaped base 21 and the center of the needle bar 104 aligned, but the first rail 22a and the second rail 22b slide. Therefore, it is not necessary to match the centers. In addition to the shape shown in the figure, by changing the configuration around the attachment portion according to the target sewing machine, the sewing machine moving device 10 can be attached to various sewing machines having the conveying device 102. It is also easy to restore the state before installation.

According to the first embodiment, since the drive device 40 is installed independently so that the relative position with respect to the sewing machine does not change even when the frame member 31 and the mounting table 32 are moved in parallel, they do not interfere with each other. It is not necessary to consider the load on the device and the rotation and movement of the wiring, and it is possible to perform efficient conveyance. High quality sewing is possible.

A brake device 26 and a base plate 23 on which the brake device 26 is arranged are provided.

  Here, the first rail 22a is provided with a brake, and the sliding of the first rail 22a can be regulated at an arbitrary position. The brake device 26 and the first rail 22a with a brake are configured by an air cylinder or a solenoid valve.

  In the second embodiment, the frame member 31 is connected to the conveying device 102 by connecting the frame member 31 and the conveying device 102 so that the conveying device 102 is conveyed to an arbitrary position in the X direction and the Y direction by the conveying motor. At the same time, the mounting table 32 moves. However, since the movement of a part of the mounting table 32 is restricted by the restricting means 20B, the moving direction of the mounting table 32 is different from the moving direction of the frame member 31, as shown in FIG. That is, the main body of the mounting table 32 moves in the rotating direction.

  By installing the first rail 22a with a brake on the mounting table 32, the operation of the first rail 22a can be regulated at an arbitrary position, so that the first rail 22a is regulated after the rotation is completed. By releasing, it is possible to shift to pattern sewing, and the sewn product moving device 10 can be rotated indefinitely.

  According to the second embodiment of the present invention, when performing the rotating operation, the conveying device 102 performs a circular motion in both the forward and reverse directions around the sewing needle 103 at a desired rotational angle, whereby the sewing product moving device 10 is moved. , And there is no dedicated power for rotation, and the sewing product can be rotated relative to the sewing needle 103.

  The sewn product moving apparatus of the present invention can be rotated indefinitely with respect to the sewing needle, can be operated independently of the conveying apparatus, and can be practically used for various sewing machines due to the feature that is independently installed on the sewing machine.
