Description

Matt lockstitch device {STITCHED DEVICE FOR MAT}

The present invention relates to a mat lockstitch device.

In general, in the case of a mat installed to prevent contamination of the floor, it is produced according to the shape of the floor surface. Therefore, the rim of the mat is formed in various shapes, and the rim member supplied for the finish is sewn to the rim of the mat. In this regard, the prior art patent document 1 (Republic of Korea Patent No. 1135545) and the prior patent document 1 (Republic of Korea Patent No. 1558155) disclose a mat member lock-stitching apparatus according to the prior art.

In the prior patent document 1, the rim cloth 90 is supplied from the rim cloth binder 50, and the tooth member 60 and the rear presser foot in a state in which the front presser foot 20 presses the sewing material 80 with the largest area as far as possible. With the action of (30), the border cloth (90) is transferred to the sewn sewing material (98), and the first needle (71) is a border cloth (50) supplied from the border cloth binder (50) to the edge of the sewing material (80) 90). And in the prior patent document 2, when the upper mat 110 is pushed in a certain direction, the first guide 310 enters the rim member 200 into the upper mat 110, and the needle 330 is sewn.

On the other hand, since various types of mats are used in recent years, in order to automatically lock the rim member on the rim of the mat, it is necessary to perform the lockstitch by switching the conveying direction of the mat according to the rim shape. In this regard, prior patent document 3 (Japanese Patent Publication No. 1995-96901) discloses a technique for stitching a border portion such as a mat by a conventional technique.

Referring to the prior patent document 3, conventionally, the detection bar 28 is fixed to the swinging arm 27 in a state in contact with the periphery of the rug 7, and the rotary angle of the swinging arm 27 is rotated by the rotary encoder 25. Detects. Therefore, in the related art, when the rug 7 is conveyed by the rollers 10 and 17, the detection bar 28 rotates according to the position of the rim of the rug 7 according to a predetermined trajectory, and the detection bar 28 ) The rotary encoder 25 detects the rotation angle of the swinging arm 27 that rotates in conjunction with the rotation, and substantially detects the position of the rim of the rug 7.

However, according to the mat lock-stitch device according to the related art, the following problems occur.

First, referring to the prior patent documents 1 and 2, conventionally, the first guide 310 to guide the border cloth binder 50 or the border member 200 for supplying the border cloth 90 is the direction in which the stitching is performed It is fixed to be positioned in front of the needle or needle. Therefore, in the related art, when the shape of the rim of the mat or the like is complicated, the distance between the tip and the mat to which the rim member is supplied may vary, and the worker must move the rim member with respect to the rim of the mat as much as the distance. .

In addition, in the prior patent documents 1 and 2, after the stitching of the border fabric 90 or the border member 200 to the border of the mat or the like is completed, the worker stitches the border fabric 90 or the border using a tool such as scissors. The member 20 should be cut from the rim cloth 90 or the rim member 20 wound in the form of a reel. Therefore, conventionally, there is a disadvantage in that the finishing work is cumbersome after the frame member is sewn to the edge of the mat.

Then, as disclosed in the prior patent document 3, in the prior art, the detection bar 28 substantially touching the rug 7 rotates along the vertical axis. In other words, conventionally, the trajectory formed by the rim of the rug 7 according to the transport of the rug 7 and the trajectory formed by the tip of the detection bar 28 that rotates in connection with the rug 7 are positioned on the same phase. On the other hand, in order for the detection bar 28 to detect the position of the rim of the rug 7, the state in contact with the rim of the rug 7 must be maintained, and for this, the trajectory and the detection bar formed by the rim of the rug 7 The trajectories formed by the tip of (28) should cross each other. By the way, as described above, the trajectory formed by the rim of the rug 7 and the trajectory formed by the tip of the detection bar 28 are located on the same plane, thereby detecting the detection bar according to the shape of the rim of the rug 7 ( The tip of 28) may not be in contact with the rim of the rug (7). That is, when the rim of the rug 7 is rapidly changed, for example, when a part of the rug 7 is recessed inside, the tip of the detection bar 28 fits the rim of the rug 7 It may become out of reach. Then, if the tip of the detection bar 28 does not come into contact with the rim of the rug 7, the rug 7 is not substantially detected by the detection bar 28 continuously. The detection of the rim of the rim becomes impossible, whereby there is a fear that the sewn to the rim of the rug 7 cannot be made accurately.

As the lockstitch unit 400, various methods widely known in the related art may be applied. However, in the present embodiment, the lockstitch unit 400 is located behind the moving block 211 in a direction in which the mat M is transferred by the transfer unit 300. Practically, the transfer speed of the mat M by the transfer unit 300, that is, the position detection of the rim of the mat M by the detection unit 201 and thus the transfer unit 300 The distance between the moving block 211 and the lockstitch unit 400 in the conveying direction of the mat M will be determined in consideration of the time difference between the varying of the conveying direction of the mat M.

In addition, the supply unit 500 supplies the frame member D that is sewn to the edge of the mat M by the lockstitch unit 400. In this embodiment, the rim member D released from the rim member reel R is supplied by the supply unit 500. For example, the supply unit 500, the rim member reel (R) is seated on the reel seating portion 510 and the reel seating portion 510 seated on the reel member R is released from the The rim member D may include a supply roller 520 that rotates by a driving force provided in a state in contact with its outer circumferential surface.

To this end, the guide unit 600 may include a fixed guide 610, a moving guide 620, a contact bracket 630, and a pusher member 640.

More specifically, the fixing guide 610 is fixed to the upper surface of the support plate 100. Here,'fixed' means that the position is fixed irrespective of the rim shape of the mat M transferred by the transfer unit 300, as well as the support plate 100 as well as the support plate 100. It may be secured to the lockstitch unit 400 fixed to the or other configuration. Practically, the rim member D supplied from the supply unit 500 flows through a space formed inside the fixing guide 610 and is transferred to the moving guide 620.

In addition, the movement guide 620 is installed on the support plate 100 to be able to move linearly in a direction adjacent or spaced apart from the fixed guide 610. Here,'move' means that the position is changed according to the shape of the rim of the mat M transferred by the transfer unit 300. For example, the movement guide 620 may be fixed to another configuration movably installed on the support plate 100 or movably installed on the support plate 100. In this embodiment, the movement guide 620 is fixed to the movement block 211. A lead-out opening 621 is defined at the tip of the movement guide 620. The withdrawal opening 621 is a place where the rim member D is withdrawn, and the rim member D may be formed in a cross section of a'┏┓' shape so as to surround the rim of the mat M. Substantially, the rim member D that flows inside the fixing guide 610 will flow out of the moving guide 620 and then withdraw through the take-out opening 621.

On the other hand, the contact bracket 630, which is in contact with the rim of the mat (M), is provided on one side of the movement guide 620. Of course, substantially, a part of the movement guide 620 may protrude or extend so as to contact the rim of the mat M to define the contact bracket 630.

In addition, in the pusher member 640, the contact bracket 630 is attached to the edge of the mat M so that the drawing opening 621 is spaced at a predetermined distance from the edge of the mat M. An external force in a contacting direction is applied to the moving guide 620. For example, as the pusher member 640, both ends of the support plate 100 and the moving guide 620 are supported, and a coil spring or the like that provides elastic force to the moving guide 620 may be used. In this embodiment, the elastic member 221 substantially functions as the pusher member 640. However, the pusher member 640 may be used as a separate member from the elastic member 221.

The cutting unit 700 cuts the rim member D which is sewn into the rim of the mat M from the rim member reel R. As the cutting unit 700, a heating wire heated to a predetermined temperature and burning one side of the frame member D may be used. Practically, the cutting unit 700 may be installed on the upper surface of the support plate 100 corresponding to the fixing guide 610 and the moving guide 620 so as to contact the rim member D.

And the control unit 800, according to the edge position of the mat (M) detected by the sensing unit 201, the transfer of the mat (M) and the frame member (D) of the mat (M) The operation of the transfer unit 300 and the lockstitch unit 400 is controlled so that the lockstitch is made at the rim. In other words, the control unit 800 determines the shape of the rim of the mat M according to the rim position of the mat M detected by the sensing unit 201, and the mat M is The transfer unit 300 and the operation of the lockstitch unit 400 are controlled so that the rim member D is sewn to the rim of the mat M while being transported. In addition, in this embodiment, the control unit 800 controls the operation of the cutting unit 700 so that the rim member D is cut from the rim member reel R.

More specifically, the control unit 800, the linear encoder 231 is detected from the continuous change in the position of the border of the mat (M) according to the change in the movement distance of the movement block 211 detected by the linear encoder 231 The shape of the rim of the mat M is judged. And the control unit 800, the transfer unit so that the frame member (D) is sewn to the edge of the mat (M) by the lock-stitching unit 400 according to the determined shape of the rim of the mat (M). Control the operation of 300.

For example, as shown in FIG. 2, in the straight section of the rim of the mat M, the movement of the moving block 211 is not made even when the mat M is transferred, so the linear encoder 231 There will be no change in the moving distance of the moving block 211 detected by ). In this case, the control unit 800 determines the rim shape of the mat M as a straight line shape.

In addition, when the edge shape of the mat M is determined to be a straight line, the control unit 800 may include the first upper roller 311 and the first lower roller 321, and the second upper roller 312. ) And the second lower roller 322 and the third upper roller 313 and the third lower roller 323 are controlled to rotate at the same speed. Thus, as shown in Figure 2, the first upper roller 311 and a portion of the mat (M) in contact with the outer peripheral surface of the first lower roller 321 and the second upper roller 312 and the second lower Another part of the mat M contacting the outer circumferential surface of the roller 322 and another part of the mat M contacting the outer circumferential surface of the third upper roller 313 and the third lower roller 323 Since each has the same displacement, while the mat M is conveyed in a straight line, the rim member D is sewn to the rim of the mat M by the lockstitch unit 400.

On the other hand, in the case of a curved section among the rims of the mat M, when the mat M is transferred, the moving block 211 moves according to the shape of the rim of the mat M, and the linear encoder The moving distance of the moving block 211 detected by 231 will be varied. And the control unit 800, in consideration of the movement direction of the movement block 211, the shape of the edge of the mat (M) in accordance with the movement distance of the movement block 211, a curved shape such as an edge or protrusion or depression. You can judge.

In addition, the control unit 800, when the edge shape of the mat (M) is determined to be a curve, the first upper portion so that the mat (M) is conveyed in a curve so that the mat (M) is conveyed in a curve The roller 311 and the first lower roller 321, the second upper roller 312, the second lower roller 322, and the third upper roller 313 and the third lower roller 323 are all different speeds. Or the first upper roller 311 and the first lower roller 321 are stationary while the second upper roller 312 and the second lower roller 322 and the third upper roller 313 and The third lower roller 323 is controlled to rotate. For example, in the case of a curved section as shown in FIG. 3 among the rims of the mat M, the first upper roller 311 and the first lower roller 321 may include the second upper roller 312. ) And the second lower roller 322 rotates at a relatively high speed, and the second upper roller 312 and the second lower roller 322 are the third upper roller 313 and the third lower roller 323 When controlled to rotate at a relatively high speed compared to ), a portion of the mat (M) in contact with the outer peripheral surface of the first upper roller 311 and the first lower roller 321, the second upper roller 312 And the second lower roller 322 has a relatively large displacement compared to the other portion of the mat (M) in contact with the outer peripheral surface, the second upper roller 312 and the outer peripheral surface of the second lower roller 322 The other part of the mat M in contact has a relatively large displacement compared to another part of the mat M in contact with the outer circumferential surfaces of the third upper roller 313 and the third lower roller 323. do. In other words, a part of the mat M in contact with the outer circumferential surfaces of the first upper roller 311 and the first lower roller 321 is the outer circumferential surface of the second upper roller 312 and the second lower roller 322. The mat (M) that moves relative to the other part of the mat (M) that is in contact with the trajectory of a relatively large radius of curvature, and contacts the outer circumferential surfaces of the second upper roller (312) and the second lower roller (322) The other portion of the third upper roller 313 and the third lower roller 323 by moving relative to the other portion of the mat (M) in contact with the trajectory of the relatively large radius of curvature, the mat ( M) is transferred in a curve.

Accordingly, the distance between the first upper roller 311 and the first lower roller 321 and the second upper roller 312 and the second lower roller 322 and the second upper roller 312 and the second lower Considering the distance between the roller 322 and the third upper roller 313 and the third lower roller 323, the first upper roller 311 and the first lower roller 321 and the second upper roller 312 ) And the difference in the rotation speed of the second lower roller 322 and the rotation of the second upper roller 312 and the second lower roller 322 and the third upper roller 313 and the third lower roller 323 By adjusting the difference in speed, the rim member D is sewn to the rim of the mat M by the lockstitch unit 400 while the mat M is transported according to various rim shapes of the mat M. Will be. For example, the difference in rotational speed between the first upper roller 311 and the first lower roller 321 and the second upper roller 312 and the second lower roller 322 and the second upper roller 312 ) And the curvature radius of the curve through which the mat M is conveyed will be reduced in proportion to the difference in rotational speed between the second lower roller 322 and the third upper roller 313 and the third lower roller 323. .

On the other hand, the control unit 800, after the frame member (D) released from the frame member reel (R) is sewn to a part of the frame of the mat (M) by the lock unit 400, the frame member ( The operation of the cutting unit 700 is controlled so that D) is cut from the rim member reel R. In other words, the control unit 800, when the rim member (D) is sewn to a part of the rim of the mat (M), by applying power to the cutting unit 700 is heated, the rim member (D) Is controlled to be cut from the rim member reel (R).

However, as described above, the cutting unit 700 is located between the fixed guide 610 and the moving guide 620. Accordingly, the control unit 800, when the rim member (D) is cut from the rim member reel (R) by the cutting unit 700, the rim member (D) the rim of the mat (M) The operation of the lockstitch unit 400 is controlled to lock the rest.

Hereinafter, a mat lock-stitch apparatus according to a second embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

Figure 4 is a front view showing a mat lock-stitch device according to a second embodiment of the present invention. Among the components of the present embodiment, for the same components as the first embodiment of the present invention described above, reference numerals in FIG. 1 are used, and detailed description thereof will be omitted.

Referring to FIG. 4, in the mat lockout apparatus 2 according to the present embodiment, a through slot 120 is formed in the support plate 100. The through slot 120 is formed by cutting a part of the support plate 100. Practically, the through slot 120 is formed in correspondence with a trajectory formed by the sensing rod 212 to be described later while rotating in association with the movement of the position of the rim of the mat M. In addition, in this embodiment, the sensing unit 202 includes a sensing rod 212, an elastic member 222 and a rotary encoder 232.

More specifically, the sensing rod 212 is interlocked with the movement of the position of the edge of the mat M according to the transfer of the mat M while at least one side is in contact with the edge of the mat M. Rotate. In this embodiment, the sensing rod 212 is rotated around an axis extending parallel to the upper surface of the support plate 100. Accordingly, a plane on which the trajectory formed by the sensing rod 212 that rotates in association with the movement of the position of the rim of the mat M is positioned will be orthogonal to the upper surface of the support plate 100. In other words, in this embodiment, the plane on which the trajectory formed by the rim of the mat M to be transferred is located, and the sensing rod 212 that rotates in association with the movement of the rim of the mat M are formed. The plane where the said trajectory is located will be orthogonal. In this way, even when the shape of the mat M is excessively complex, the plane where the trajectory formed by the rim of the mat M is located and the plane where the trajectory where the sensing rod 212 is formed are orthogonal are orthogonal are formed. , It is possible to maintain the state in which the sensing rod 212 is in contact with the rim of the mat (M). In addition, when the sensing rod 212 remains in contact with the edge of the mat M, it is possible to continuously sense the position of the edge of the mat M.

Further, in the present embodiment, in the state where the tip of the sensing rod 212 penetrates the through slot 120, it rotates in association with the movement of the position of the rim of the mat M. That is, substantially, the sensing rod 212 is rotated in connection with the transfer of the mat M in a state where the tip is located below the support plate 100, that is, below the mat M. will be. Therefore, in this embodiment, even when the thickness of the mat M is excessive, the phenomenon that the sensing rod 212 rides on the mat M can be prevented.

Meanwhile, the elastic member 222 imparts elastic force in the direction in contact with the rim of the mat M to the sensing rod 212. Therefore, in the state in which the sensing rod 212 is in contact with the edge of the mat M by the elastic force of the elastic member 222, the position of the edge of the mat M according to the transfer of the mat M It rotates continuously in connection with movement.

The rotary encoder 232 detects the rotation angle of the sensing rod 212. Practically, the rotary encoder 232 rotates the angle of rotation of the sensing rod 212 in both directions, that is, in the forward/reverse direction, based on the position where the sensing rod 212 contacts the edge of the mat M.
