Description

  The present invention relates to a sewing machine for performing sewing such as embroidery sewing on a curved heel of a hat, and further relates to a sewing machine suitable for sewing other curved objects to be sewn. The present invention relates to a holding frame for holding a body, and further to a sewing machine using the holding frame.

Hat collars are made by sandwiching and sewing a thick core made of urethane, etc., approximately the same shape between the front and back fabrics. An industrial sewing machine is used for the sewing, and the front fabric, the back fabric, and the core material are sewn together by simple running stitches as shown in FIG. The form of the core material may be a flat plate or may be pre-curved into an arc shape, but in any case, a special material that integrally holds the front fabric, the back fabric, and the core material. The sewing operation is performed manually by the sewing machine operator using a simple attachment.
By the way, in recent years, various decorations have been popular on the upper surface of the hat collar, and one of the decoration methods is to give embroidery with excellent design. When embroidery is to be performed, the structure composed of the front fabric, the core material, and the back fabric is converted into embroidery data of a predetermined embroidery pattern within a plane perpendicular to the reciprocating movement direction (vertical direction, up and down direction) of the sewing needle of the sewing machine. It is necessary to control the movement in the XY direction based on this. However, if the core material is flat, that is, if the structure composed of the front fabric, the back fabric, and the core material is flat, it can be implemented in an existing embroidery machine, but the core material is curved. There is no conventional sewing machine that can be embroidered in a curved state when it is a material, that is, when a constituent body composed of a front fabric, a back fabric, and a core material is curved.
On the other hand, in order to perform automatic embroidery sewing on the cap part of the cap and other tubular objects, it can be rotated around the hook base (cylinder bed containing the hook) and linearly in the direction of the rotation axis. There are known sewing machines in which a holding frame is mounted on a movable drive ring, and a cylindrical workpiece is set on the holding frame to perform embroidery sewing (for example, Japanese Patent No. 3190500 and Japanese Patent Laid-Open No. 2000-2000). 355867). However, such a conventionally known holding frame is suitable for setting the cap portion of the hat and other cylinders because it covers the sewing object, but it has other shapes, that is, It cannot be applied to a curved shape that is less than the entire circumference.
The type of cap hat such as a baseball cap is more expensive because a type in which a flat heel is appropriately bent by a user by hand is preferentially bent into an ideal curved shape at the manufacturing stage. . In addition, an item in which an arbitrary embroidery is applied to the heel portion is preferred by the user as a higher quality product. However, in the case where the heel is formed in an ideal curved shape in advance at the manufacturing stage, as described above, conventionally, embroidery can only be performed manually, which takes time and manufacturing cost. There was a problem of becoming expensive.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and is intended to provide a sewing machine that can easily perform sewing such as embroidery sewing on a curved heel of a hat. It is intended to provide a holding frame suitable for holding. Furthermore, the present invention is intended to provide a holding frame suitable for holding other curved objects to be sewn and a sewing machine using the same, without being limited to the hat collar.
A holding frame according to the present invention is a holding frame for holding a sewing object so as to be rotatable around a pot base of a sewing machine and to be linearly movable in the direction of the rotation axis, A receiving frame portion for holding a curved sewing object to be sewn within a range that is less than the circumference, and a fixing means for fixing the sewing object held by the receiving frame portion to the receiving frame portion. It is characterized by comprising. In addition, the sewing machine according to the present invention includes such a holding frame.
According to the present invention, the receiving frame portion of the holding frame is configured to hold the curved sewing target object to be sewn within a range that is less than the entire circumference. Thereby, the to-be-sewn body that is the object to be sewn can be securely held by fitting to the object to be sewn that is not a cylinder. And, by providing a fixing means for fixing the sewing object held by the receiving frame part to the receiving frame part, the sewing object held by the receiving frame part is fixed and a sewing operation is performed. Sometimes the holding frame can be moved without inconvenience.
In a preferred embodiment, the receiving frame portion has a plurality of holding members that hold the sewing body by fitting or gripping the edges of the sewing body at predetermined positions, and are surrounded by the holding members. The receiving frame portion is opened in a space to be opened. Thereby, since the receiving frame portion is opened in the space surrounded by the holding members, a wide embroidery range is ensured. That is, the embroidery can be performed up to the periphery of the body to be sewn.
A curved body to be sewn, which is an object to be sewn, is, as a typical example, a cap hat collar, and includes a front fabric, a back fabric, and a core material curved with a predetermined curve sandwiched therebetween. By performing the sewing operation while the holding frame is driven biaxially (linear driving and rotational driving) based on the embroidery data, it is possible to perform desired embroidery sewing on the curved heel component held by the holding frame. it can. If this embroidery stitching operation is performed with the heel component temporarily fixed or temporarily fixed with an adhesive or the like, sewing work for integrating the heel component and decorative sewing (embroidery sewing or special thread) Can be used at the same time. Therefore, the process can be simplified. Of course, since the embroidery sewing for the curved heel can be automated, the process can be simplified in this respect as well.
As one embodiment, the holding member can adjust its arrangement position in the receiving frame portion in accordance with the shape of the sewing object. As a result, it is possible to cope with large and different shape ridges.
As one embodiment, the fixing means includes a lock member for locking the sewing body to the receiving frame portion, and the lock member is selected to one of a lock position and an unlock position according to driving of the actuator. Controlled. As a result, it is possible to automatically lock the hook held on the holding frame so as not to be released and to release (unlock) this lock by driving the actuator without human intervention, thereby improving work efficiency. .
As an embodiment, the sewing machine has a drive ring that can rotate around the pot base and linearly move in the direction of the rotation axis, and the holding frame is detachably attached to the drive ring. By doing so, it can be attached to and detached from the sewing machine. As a result, the holding frame is detachable. For example, at least two holding frames are prepared and removed from the sewing machine when one holding frame is set on the sewing machine and embroidery sewing is performed on the bag. The heel for the next embroidery sewing work can be attached to the other holding frame. When the embroidery sewing is completed, the holding frame is removed from the sewing machine and the heel for the next embroidery sewing work is already attached. Since the frame can be attached to the sewing machine and the next embroidery sewing operation can be performed immediately, the efficiency is improved. In particular, a multi-head sewing machine having a plurality of sewing heads and a plurality of pot bases (cylinder beds) is very effective. When the holding frame is detachable as described above, if it is difficult to separate the holding frame from the actuator that controls the locking member, the locking member should be manually locked or unlocked without using the actuator. Good.
As one embodiment, the fixing means biases the lock member in a direction to release the fixation of the sewing body with respect to the receiving frame portion and a lock member for locking the sewing body to the receiving frame portion. A biasing means for locking the structural member to the receiving frame portion by the lock member, locking the resist against the biasing force of the biasing means, and releasing the lock The lock member is moved in a direction to release the fixation of the sewing body by the urging force of the urging means. Accordingly, when the lock by the lock member is released, the urging means moves the lock member in the direction to release the fixation of the sewing object, so that the trouble of manually operating the lock member is saved, and the receiving frame of the sewing object is eliminated. Can be easily fixed to and removed from the unit with a single touch.
As one embodiment, the fixing means includes a clamp member attached to the receiving frame portion, and the clamp member holds a position where the edge of the sewing object set on the receiving frame portion is held and the holding portion. It is possible to switch to any one of the positions to cancel.
In one embodiment, the body to be sewn is a heel structure for a heel of a hat. In this case, the holding frame may be configured such that the heel structure can be set on the receiving frame portion with the heel front portion of the heel structure facing rearward, and conversely, the heel structure You may comprise so that this heel structure may be set to the said receiving frame part with the heel front part facing forward. In the latter case, the receiving frame portion includes a holding member that holds at least one of the front edge portions of the set saddle structure, and engages both ends of the rear edge portion of the set saddle structure. In order to stop, it is good to further provide a pair of stoppers. Thus, by holding both ends of the rear edge portion of the saddle structure with stoppers, it is possible to hold the front edge portion of the saddle structure set by the holding member only by holding the front edge portion of the saddle structure. The structure can be stably supported.

First, an embodiment in which the present invention is applied to a single-needle single-head embroidery sewing machine will be described with reference to FIGS.
FIG. 1 is a perspective view of the entire single needle single head embroidery sewing machine. A sewing arm 2 is installed on the upper surface of the sewing table 1. The front part of the sewing machine table 1 is divided, and the front table 1a is lowered downward by a predetermined height. Below the sewing machine arm 2 is installed a cylinder bed (pot base) 4 whose upper surface is set to be substantially the same as the height of the upper surface of the sewing machine table 1. A rotary hook that performs main sewing by cooperating with the needle bar is housed inside the tip of the cylinder bed (pot base) 4, and its upper surface is covered with a needle plate 9. In addition, the hole 1b long drilled in the front and rear in the center of the front table 1a is for letting the cylinder bed (pot base) 4 escape when the front table 1a is set at the same height as the sewing machine table 1. One needle bar is supported on the sewing machine head 3 provided at the front end of the sewing machine arm 2 so as to be vertically movable.
A Y-direction driver 5 is provided on the table 1 below the sewing machine arm 2. The left and right ends of the Y-direction drive body 5 are respectively coupled to carriers of a Y-direction drive unit (not shown) installed on the lower surface of the sewing machine table 1, and are driven in the Y direction (front-rear direction) by driving both drive units. It is designed to move. An X-direction drive unit is incorporated in the Y-direction drive body 5, and an X-direction drive plate 6 (see FIG. 2) supported so as to be movable in the X direction inside the Y-direction drive body 5 The X-direction drive motor 7 fixed to the right end is driven to move in the X direction. A holding frame 8 for holding a curved body to be sewn that is a sewing target is attached to the lower surface of the substantially central portion of the Y-direction driving body 5. In the present embodiment, the curved body to be sewn, which is a sewing target, is a hat collar structure V as shown in FIGS. 7 (a) and 7 (b). As described above, the heel component V is formed by sandwiching the core material between the front fabric and the back fabric as shown in the perspective view of FIG. As shown, it is curved in advance to a predetermined curve as a whole. In addition, for example, the front and back fabrics are overlapped, and the edges excluding the rear edge of the heel (the part sewn on the hat) are stitched together, and the curved core material is put into the bag-shaped one. The saddle construction V is constructed.
2 is an enlarged plan view showing a portion of the holding frame 8, and FIG. 3 is a front view thereof. 2 is a cross-sectional view taken along line AA in FIG. 2, that is, a view of the holding frame 8 seen from the side, and FIG. 5 is a cross-sectional view taken along line BB in FIG. It is shown. FIG. 6 is a perspective view of the holding frame 8.
As shown in FIGS. 2 to 5, a pair of mounting plates 11 located on both sides of the cylinder bed (pot base) 4 are attached to the lower surface of the Y-direction drive body 5. Move in the direction. A support plate 12 is fixed to the front end of the mounting plate 11, and the drive ring 10 is rotatably supported on the front surface of the support plate 12. A linear guide 14 is fixed to the rear surface of the support plate 12, and the linear guide 14 is slidably fitted to a linear rail 16 fixed to the lower surface of the cylinder bed 4. As a result, the support plate 12 (and the drive ring 10) stably moves back and forth in the Y direction, but does not move in the X direction.
As shown in FIG. 3, three rollers 15 are rotatably attached to the front surface of the support plate 12 in a predetermined arrangement along the inner peripheral surface of the drive ring 10. The inner peripheral surface of the drive ring 10 is supported by the three rollers 15 so as to be freely rotatable. Specifically, a protrusion 15a is provided on the outer periphery of each roller 15 and is fitted into a groove 10a provided on the inner periphery of the drive ring 10, so that the drive ring 10 extends along the circumference of the ring. It can be rotated. A wire 17 is wound around the outer periphery of the drive ring 10 and both ends thereof are connected to the X-direction drive plate 6 of the X-direction drive unit via a pair of fixing members 18. Therefore, when the X-direction drive plate 6 moves in the X direction by driving the X-direction drive motor 7, the drive ring 10 is rotationally driven via the wire 17 accordingly. The holding frame 8 of this embodiment is attached to the front end of the drive ring 10 with a plurality of bolts 20. Thereby, the holding frame 8 rotates and linearly moves in the Y direction in accordance with the rotational movement according to the X direction driving of the driving ring 10 and the linear movement along the rotation axis according to the Y direction driving.
The holding frame 8 is configured by a receiving frame portion 27 having a generally cylindrical shape and holding members 21a, 21b, and 21c attached to the receiving frame portion 27, and further includes a pressing member 28 (that is, a lock member). It is out. That is, the main part of the holding frame 8 is constituted by a receiving frame part 27, and the holding frame 8 is attached to the driving ring 10 by attaching the receiving frame part 27 to the driving ring 10 by a plurality of bolts 20. It has been. Although the receiving frame portion 27 has a cylindrical shape as a whole, the receiving frame portion 27 is not a complete cylinder, and a part of a side peripheral surface of the cylinder is relatively largely removed to form an opening. The structural body V to be sewn is set on the receiving frame portion 27 so as to cover the opening, and holding members 21a, 21b, 3 provided at three locations on the receiving frame portion 27 as described below. 21c is fitted and held. This opening is for allowing the needle fed out from the sewing machine head 2 toward the shuttle in the cylinder bed 4 to the structural body V to be sewn set in the receiving frame portion 27. Therefore, the spread of the opening defines the embroidery range for the sewing structure V set on the receiving frame 27. Therefore, if this opening is a shape to be sewn that is held by the receiving frame 27 and substantially conforms to the shape of the heel, the embroidery range can be widened, and the heel can be as much as possible. This is preferable because embroidery can be applied over a wide range.
In the receiving frame portion 27, three holding members 21a, 21b, and 21c are provided on the peripheral portion of the opening. The mounting positions of the holding members 21a, 21b, and 21c with respect to the receiving frame portion 27 can be adjusted as will be described later. One holding member 21a is arranged at the center of the front end of the opening of the receiving frame 27, and the other two holding members 21b and 21c are arranged at symmetrical positions of the opening.
As shown in FIG. 6, FIG. 2, etc., each holding member 21a-21c is comprised with the board | substrate 22 used as the attaching part to the receiving frame part 27, and a pair of guide plate 23 attached so that this might be pinched | interposed from both sides Has been. A groove formed between the pair of guide plates 23 becomes a fitting groove 125 that fits and holds the edge portion of the ridge structure V.
Fig.7 (a) is a top view of the structure V of the bag which consists of a front fabric, a back fabric, and a core material. As shown in the figure, when the curved saddle structure V is set on the receiving frame 27, the front edge of the collar fits into the fitting groove 125 of the holding member 21a on the front edge, and the left and right edges of the basket Are fitted in the fitting grooves 125 of the holding members 21b and 21c at the left and right edges, respectively. The edge of the substrate 22 forms the bottom of the fitting groove 125. The saddle structure V fitted in the fitting groove 125 is locked in three directions by a pair of guide plates 23 forming both side walls of the groove 125 and the edge of the base plate 22 forming the bottom. As a result, the receiving frame 27 is held immovably.
In each of the pair of left and right holding members 21b and 21c, a long hole H (see FIGS. 4 to 6) for bolt attachment is formed in the substrate 22 at two locations, and the bolt passed through the long hole H 24, the holding members 21b and 21c are attached to the receiving frame portion 27 by being screwed into the screw holes of the receiving frame portion 27. At this time, the long holes H with the bolts 24 loosened. By appropriately moving the holding members 21b and 21c along the direction, the arrangement of the holding members 21b and 21c with respect to the receiving frame portion 27 (description position) can be adjusted. The length direction of the long hole H is along the circumferential direction of the drive ring 10, that is, the rotational direction of the receiving frame portion 27, and both holding members 21 b and 21 c are respectively in the circumferential direction with respect to the receiving frame portion 27. The arrangement position can be adjusted. Thus, the arrangement of the pair of left and right holding members 21b and 21c is adjusted so as to fit the horizontal size (x in FIG. 7A) of the heel structure V to be sewn. The receiving frame 27 can be securely held. In this embodiment, the arrangement of the holding member 21a that holds the front edge portion of the saddle structure V is fixed at a predetermined position and cannot be adjusted. This is done by setting the front edge portion of the heel component V in a state where the front edge portion is fitted into the fitting groove 125 of the holding member 21 a and pressed against the bottom thereof, and the rear edge portion is set to the press member 28 at the tip of the press arm 25. This is because it is possible to prevent backlash associated with the front and rear of the bag structural body V by pressing and locking with the (locking member). However, the present invention is not limited to this, and the arrangement of the holding member 21a that holds the front edge portion with respect to the receiving frame portion 27 may be adjusted as necessary.
The above-described three holding members 21a to 21c are prevented from moving by the pair of left and right holding members 21b and 21c with respect to the movement of the sewing structure V set in the receiving frame portion 27 in the left-right rotation direction. It is firmly held by the holding member 21a that holds the front edge of the structure V and is firmly fixed to one movement in the linear direction along the rotation axis (movement toward the rear of the table 1). And held. Moreover, it is hold | maintained firmly with respect to the motion of the up-down direction perpendicular | vertical to the surface of the to-be-sewn structure V so that it may not rattle by each holding member 21a-21c.
Further, the presser arm 25 is pivotally supported by the shaft 26 and is swingably disposed on the receiving frame portion 27. The presser arm 25 and the presser member 28 attached to the tip end portion of the presser arm 25 function as a fixing means for fixing the sewing component V held by the receiving frame portion 27 to the receiving frame portion 27. In the receiving frame portion 27, a support surface 27a is formed at a position facing the holding member 21a at the front edge portion, and a presser member 28 (that is, a lock member) at the distal end portion of the presser arm 25 is above the support surface 27a. To position. The presser member 28 is attached by a long hole provided in the presser arm 25 so that the position in the front-rear direction (the axial direction of the receiving frame portion 27) can be adjusted. Since the mechanism for adjusting the position may be the same as the mechanism for adjusting the position of the holding members 21b and 21c described above, detailed description thereof will be omitted. As a result, the arrangement of the presser member 28 is adjusted so as to fit the size (y in FIG. 7A) in the front-rear direction of the heel structure V to be sewn. And can be held.
As shown in FIGS. 4 and 5, an actuator 31 such as an air cylinder is disposed outside the receiving frame 27 on the opposite side of the opening, and its base end is swingably connected to the drive ring 10. Yes. The tip of the drive rod 32 of the actuator 31 is pivotally supported by a drive arm portion 30 that is integrally connected to the presser arm 25. For example, the air cylinder that is the actuator 31 is connected to an air pressure supply source (not shown) via a direction switching valve (not shown), and the rod of the actuator 31 is pushed each time a foot switch (not shown) installed at the sewing operator's foot is pressed. 32 projecting motions and retreating motions operate alternately. When the rod 32 is protruded, the drive arm portion 30 of the presser arm 25 rotates around the shaft 26 in the clockwise direction in FIG. 4, and the presser member 28 at the tip of the presser arm 25 is moved in the direction of the bearing surface 27a. The presser arm 25 as a whole assumes a posture shown by a solid line in FIG. As a result, the collar member V in which the presser member 28 is held by the receiving frame portion 27 is pressed from above at the place of the support surface 27a, and is sandwiched between the presser member 28 and the support surface 27a and fixed. (Lock). On the other hand, when the rod 32 is retracted, the drive arm portion 30 of the presser arm 25 is rotated counterclockwise in FIG. 4 around the shaft 26, and the presser arm 25 assumes the posture shown by the imaginary line in FIG. The lock of the structure V is released.
When setting the collar member V to be sewn to the frame 27, the center of the front edge of the collar member V is fitted into the fitting groove 125 of the holding member 21a, and the left and right edges are respectively held by the holding members. It is made to fit in the fitting groove 125 of 21b, 21c. Then, when the foot switch is turned on, the presser arm 25 is rotated in the clockwise direction in FIG. 4, and the center portion where the rear edge portion of the heel component V is depressed is pressed by the presser member 28 at the tip. As shown in FIG. 5, the details of the pressing member 28 are configured by a contact piece 28 a for pressing the heel component V held by the receiving frame portion 27 from above and a guide piece 28 b protruding slightly from the tip edge. In particular, the anchor structure V held by the receiving frame portion 27 is fixed (locked) by pressing by the abutting piece 28a. In this way, the hook structure V held by the receiving frame portion 27 is securely held and attached to the receiving frame portion 27 so as not to flutter.
FIG. 7C is an enlarged cross-sectional view illustrating a state in which the heel component V having the core material Vc between the front fabric Va and the back fabric Vb is pressed and locked by the presser member 28. Has been. As shown in the drawing, the rear edge ends of the front fabric Va and the back fabric Vb are appropriately longer than the rear edge ends of the core material Vc sandwiched therebetween, and the abutting piece 28a of the pressing member 28 is formed of the core material Vc. The portion consisting only of the front fabric Va and the back fabric Vb is pressed from above so as to lock the rear edge of the rear fabric. Therefore, the abutting piece 28a of the pressing member 28 has a thickness that substantially corresponds to the thickness of the core material Vc. Of course, the portion including the core material Vc can be appropriately pressed from above by the guide piece 28b protruding slightly from the abutting piece 28a.
In this way, when holding the saddle structure V on the receiving frame 27, the holding members 21a to 21c and the pressing member 28 (lock member) only hold a very small portion of the peripheral edge of the saddle structure V. For this reason, all other parts of the heel structure V can be subjected to embroidery sewing. That is, as described above, the range of the receiving frame portion 27 other than the holding members 21a to 21c and the pressing member 28 can be formed wide so as to be as open as possible, and a wide embroidery range can be secured. Can do.
When performing embroidery stitching and other sewing operations, the X-direction drive unit and the Y-direction drive unit are driven in accordance with a desired sewing pattern in synchronization with the vertical movement of the needle so that the drive ring 10, that is, the holding frame 8 is moved. By rotating and linearly moving in the axial direction, the desired sewing pattern is sewn up on the heel structure V held by the holding frame 8.
The pressing member 28 is not limited to the example in which the actuator 31 performs the lock / unlock control, but may be configured to perform the lock / unlock control by a manual operation. An embodiment in that case will be described with reference to FIGS.
As shown in the plan view of FIG. 8 and the side view of FIG. 9, a slider 41 is supported by a guide member 40 fixed to the upper surface of the receiving frame portion 27 so as to be slidable in the front-rear direction. Is fixed. The slider 41 is urged forward (in a direction away from the holding member 21a) by the elastic force of the coil spring 43 attached between the end surface of the guide member 40. A ratchet gear 41 a is formed on the upper surface of the slider 41. The ratchet lever 44 pivotally supported on the upper side of the ratchet lever 44 is urged by a torsion spring (not shown) in the direction in which the claw 44a at the tip engages with the ratchet gear 41a. As described above, in the second embodiment shown in FIGS. 8 to 10, the fixing means for fixing the to-be-sewn component V held by the receiving frame portion 27 is for manually operating the presser member 28. The slider 41, the ratchet mechanism, the coil spring 43, and the like are included.
When the heel structural body V is locked, the operation portion 41b at the end of the slider 41 is pushed and slid until the presser member 28 contacts the structural body V, and the claw 44a engages with the ratchet gear 41a at that position. Thus, the lock is completed at that position (FIG. 10B). When the lock is released, the ratchet is released by pressing the pressing portion 44b of the ratchet lever 44, and the slider 41 slides forward by the elastic force of the coil spring 43 to release the lock (FIG. 10A). As described above, when the lock is released, the slider 41 is immediately slid forward by the extension restoring force of the coil spring 43 that has been compressed simply by performing a one-touch operation of pressing the ratchet lever 44. The presser member 28 is automatically slid in the unlocking direction. Therefore, the manual operation of locking / unlocking can be performed easily and quickly with one touch.

FIG. FIG. 13 and FIG. 14 are a plan view and a front view showing an extracted configuration related to the backing plate 201. Since the configuration other than the configuration related to the receiving plate 201 is the same as that shown in FIGS. 8 to 10, only the configuration related to the receiving plate 201 will be described.
As shown in FIG. 13 and FIG. 14, two stays 200 are attached to the front surface of the support plate 12, and a receiving plate 201 that is curved in a semi-cylindrical shape is attached to the upper surface of the tip of the stay 200. A mounting hole 204 is provided in the receiving plate 201, and the receiving plate 201 is fixed by screwing the mounting hole 204 through a screw 202 to the upper surface of the tip of the stay 200. An elongated through hole 203 is formed in the front and rear in the center portion of the receiving plate 201. This through-hole 203 corresponds to the position of the hook provided in the cylinder bed 4 (pot base), and allows the sewing needle to pass through the needle hole 205 of the needle plate 9 from the upper sewing head 3. It is.
11 and 12, the receiving plate 201 is inserted into a substantially cylindrical space in the receiving frame portion 27 of the holding frame 8, and is fixed to the support plate 12 as described above. The holding frame 8, that is, the receiving frame portion 27 can be moved linearly but is not rotated together. The upper surface of the receiving plate 201 is hardly in contact with the heel component V set on the receiving frame portion 27, and may be partly touched when the needle is inserted. If not, it is not intended to support the saddle construction V. Rather, by covering the opening of the receiving frame portion 27 with the receiving plate 201 at the lower side, when the saddle structure V is set on the holding frame 8, the saddle structure V is prevented from falling off from the relatively large opening. In addition, it plays the role of facilitating the installation work of the bag structure V.
In each of the embodiments described above, the holding frame 8 is fixed to the drive ring 10 so that it cannot be easily removed via the plurality of bolts 20, but the present invention is not limited thereto, and the holding frame 8 is detachably attached. It may be. Further, the present invention may be applied to a multi-head sewing machine having a plurality of sewing heads 3. Further, the present invention is not limited to a sewing machine specialized for embroidery (sewing) on the curved heel structural body V, and a drive frame body for attaching and moving an object to be sewn can be used for various types of drive frame bodies. The present invention can also be applied to a versatile sewing machine that can be arbitrarily replaced with one of them. The embodiment shown in FIGS. 15 to 17 is one in which such various modifications are applied, that is, an example in which the present invention is applied to a multi-head sewing machine, and an example in which the holding frame 8 is detachably attached. FIG. 15 is a plan view, and FIG. 16 is a cross-sectional view taken along the line C-C in FIG. 15. 15 to 17 show examples in which these modified examples are implemented together, but the present invention is not limited to this example, and these modified examples may be alternatively employed as appropriate. Of course.
FIG. 15 shows a four-headed embroidery sewing machine in which four cylinder beds (pot bases) 104 are installed at predetermined intervals in the X direction corresponding to each of a plurality of (four) sewing heads (not shown). 2 shows a state in which the frame driving unit 100 according to the embodiment of the present invention is attached, and the holding frames 118 are set on the four driving rings 107 installed in the frame driving unit 100, respectively.
A long Y-direction drive body 105 extends in a direction crossing each cylinder bed 104 and is linearly driven in the Y direction (front and back) on the sewing machine table 101 in the same manner as the Y-direction drive body 5 described above. In addition, as shown in FIG. 16, an X-direction slide body 106 that is slidably driven in the X direction inside the Y-direction drive body 105 is provided.
As shown in FIG. 16, a support plate 108 similar to the above-described support plate 12 is provided for each cylinder bed 104, and each support plate 108 has a drive ring 107 similar to the above-described drive ring 10 in the same manner as described above. Each is attached to be freely rotatable. Each support plate 108 is attached to a pair of attachment plates 111 in the same manner as the support plate 12 is attached to the pair of attachment plates 11. A pair of mounting plates 111 for each of the support plates 108, that is, for each drive ring 107, is connected to one connecting plate 110 that is long in the X direction. On the upper surface of the connecting plate 110, one driving plate 112 that is also long in the X direction is engaged so as to be slidable in the X direction. Similarly to the wire 17 described above, both ends of the wire wound around each drive ring 107 are connected to the front edge of the drive plate 112, and each drive is driven according to the linear movement of the drive plate 112 in the X direction. The ring 107 is rotated. Similar to the holding frame 8, a holding frame 118 for holding the body to be sewn, that is, the heel component V, can be freely attached to and detached from each drive ring 107. The connecting plate 110 is fixed to the base of the Y-direction drive body 105 by tightening screws 115, and the drive plate 112 is fixed to the X-direction slide body 106 by tightening screws 116. Therefore, when the X-direction slide body 106 moves linearly in the X direction, the connecting plate 110 and each support plate 108 fixed thereto do not move, and the drive plate 112 moves linearly in the X direction and drives accordingly. The ring 107 and each holding frame 118 attached thereto are rotated. Further, when the Y-direction drive body 105 moves linearly in the Y direction, the elements (including the drive ring 107 and the holding frame 118) shown in FIGS. 15 and 16 except for the cylinder bed 104 are linear in the Y direction. Moving.
Each drive ring 107 is provided with a lock mechanism 121 at two upper portions thereof, and a corresponding holding frame 118 is mounted via the two lock mechanisms 121. A retainer portion 120 is fixedly formed at the base of the holding frame 118. When the holding frame 118 is attached to the drive ring 107, the retainer portion 120 is manually held and pushed into the drive ring 107 to hold the retainer frame 118. A lock member (not shown) provided on the base portion or the retainer portion 120 is engaged and locked with the lock mechanism 121, and thus the holding frame 118 is fixed to the drive ring 107. When removing the holding frame 118 from the drive ring 107, the release levers 122 of the lock mechanisms 121 on both sides are pushed down to release the lock, and the holding frame 118 is pushed forward by the elastic force of the spring member 123, and can be easily removed. It is like that. Since the lock mechanism 121 itself may be a known lock mechanism of this kind, its detailed description is omitted.
The structure of each holding frame 118 may be substantially the same as the structure of the holding frame 8 described above. However, in the multi-head system, the overall weight increases, so the load on the driving source increases. In addition, as shown in FIG. 16, it is preferable that the opposite side (that is, the lower side) of the opening portion of the receiving frame portion 127 constituting the holding frame 118 is greatly cut out. Of course, such a large notch on the opposite side (that is, the lower side) may be provided also in the receiving frame portion 27 in the above-described embodiment. In addition, the presser member 28 (lock member) for locking the collar structure V held by the receiving frame portion 127 is provided with a spring-biased slider 41 and a ratchet, as in the embodiment shown in FIGS. A manual operation type composed of a mechanism and a ratchet lever 44 may be used. This is because the use of the actuator 31 complicates the attachment / detachment structure of the holding frame 118. In the example shown in FIG. 16, the holding members (21b and 21c in FIG. 2 and others) provided at the left and right edges of the opening of the receiving frame 127 are provided with two holding members 21b1 and 21b2 per side. Yes. Thus, when the holding members 21b1 and 21b2 divided into two per side are used, there is an advantage that it is easy to adapt to a change in the shape of the sewing object, that is, the heel structure V.
In FIG. 17, the frame drive unit 100 including the connecting plate 110 formed by connecting the four drive rings 107 via the support plate 108 and the mounting plate 111 and the driving plate 112 slidingly engaged with the connecting plate 110 is removed from the sewing machine body. In addition, a state in which the holding frame 118 is removed from each drive ring 107 is shown. When attaching / detaching the frame driving unit 100 to / from the sewing machine, it is easy to perform the attaching / detaching work with the holding frames 118 removed from all the driving rings 107 as shown in FIG. When the unit 100 is attached to the sewing machine, the coupling plate 110 is placed on the cylinder bed 104 so that each cylinder bed 104 is fitted in each drive ring 107, and a screw 115 (FIG. 16) is attached to the lower surface of the Y-direction drive body 105. Fix by tightening (see). Next, the upper drive plate 112 is fixed to the X-direction slide body 106 of the Y-direction drive body 105 by tightening with a screw 116 (see FIG. 16). Then, the holding frames 118 on which the body to be sewn, that is, the heel component V is set in advance, are fitted into the drive rings 107 and fixed via the lock mechanism 121.
Thus, since the holding frame 118 is detachable from the drive ring 107, the following efficient work can be performed. While performing embroidery stitching on the heel component V held by the holding frame 118 set on each drive ring 107, the heel component V to be embroidered next is mounted on another holding frame 118. Keep it. When the embroidery is completed, each holding frame 118 is removed from the driving ring 107, the other holding frame 118 on which the collar V is already mounted is set on the driving ring 107, and the holding frame 118 set on the driving ring 107 is set. The next embroidery sewing operation is immediately performed on the heel structure V held by the heel. While this embroidery is being executed, the embroidery heel component V held by the holding frame 118 that has been removed from the drive ring 107 is removed and replaced with an unembroidered heel component V. By exchanging the holding frame 118 in this way, the embroidery work can be performed extremely efficiently.
When the sewing machine is used for other purposes such as normal flat embroidery or embroidery on a cylinder such as a hat or bag, each holding frame 118 is removed from each drive ring 107 and the screws 115 and 116 described above are attached. The frame drive unit 100 including the connecting plate 110 formed by connecting the plurality of driving rings 107 via the support plate 108 and the mounting plate 111 and the driving plate 112 slidingly engaged therewith is removed from the sewing machine. Instead, a frame unit having a desired function, such as a normal flat embroidery frame unit or a tubular embroidery frame unit such as a hat or bag, is attached to the sewing machine and tightened via the screws 115 and 116 described above. Fix it. That is, the frame units having various functions can be exchanged by being fastened and fixed at the same location via the screws 115 and 116 described above.
In each embodiment, it is preferable that the bottom of the fitting groove 125 of the holding members 21a, 21b, 21c, 21b1, and 21b2 provided on the receiving frame portions 27 and 127 can be always protruded by spring bias. Then, even if the size of the sewing structure V to be fitted in the fitting groove 125 is slightly changed, the bottom of the fitting groove 125 is always in contact with the edge of the sewing structure V by the spring bias. It will be adjusted and convenient.
Note that the present invention is not limited to the hat collar, and various other types having a curved shape in advance and having a size that is less than the entire circumference of the holding frame 8 or 118 attached to the drive ring. It can also be applied to embroidery stitches, decorative stitches, and other sewing operations. Further, in that case, the body to be sewn does not necessarily have to be composed of a plurality of fabrics or core materials, and may consist of a single material.
The structures or configurations of the holding members 21a, 21b, 21c, 21b1, 21b2 and the lock member 28 provided on the receiving frame portions 27, 127 are not limited to those shown in the above-described embodiment, and the main point is that the structure to be sewn is used. Any structure or configuration that can be held and fixed to the receiving frame portion may be used.
For example, in the above embodiment, the holding members 21a, 21b, 21c, 21b1, 21b2 and the lock member 28 provided on the receiving frame portions 27, 127 have different structures, but these have substantially the same structure. It does not matter. For example, the lock member 28 may be formed of a member that forms a movable fitting groove 125 having the same structure as the holding member 21b or 21c. In that case, the movable range of the movable holding member (fitting groove forming member) corresponding to the lock member 28 should be relatively large. And when setting the to-be-sewn component V in the receiving frame 27, the movable holding member (fitting groove forming member) corresponding to the lock member 28 is retracted relatively large, and the to-be-sewn component V is set. The front edge portion and the left and right side edge portions are fitted into the fitting grooves 125 of the holding members 21 a to 21 c to hold the construction member V to be received by the frame portion 27. Finally, the movable member corresponding to the lock member 28 is movable. The holding member (fitting groove forming member) of the type is advanced toward the sewing component V, and the edge of the sewing component V is fitted into the fitting groove, and the movable holding member (fitting) The groove forming member) may be fixed by screwing. In this case, the operation is somewhat troublesome, and the fixing force is not always exhibited sufficiently, but it serves as a fixing means, and is included in the scope of the present invention.
In each of the above-described embodiments, the holding frame (8, 118) has the receiving frame portion (27, 127) so that the cap collar as the sewing object V is set rearward in the holding frame (8, 118). The holding frame (8a to 21c), the presser member (28) and the like are not limited thereto, but the holding frame (8 , 118) may be changed. An embodiment of the holding frame 8A configured to set the hat heel (the heel structure V) forward will be described with reference to FIGS. FIG. 18 is a plan view showing an example of the structure of such a holding frame 8A, FIG. 19 is a front view thereof, and FIG. 20 is a view partially showing a front view similar to FIG. . 21 and 22 show side views of the holding frame 8A with respect to different operating states.
As shown in FIG. 18, the receiving frame portion 301 constituting the main portion of the holding frame 8A is attached to the drive ring 10 (or 107) as in the above embodiments. When the holding frame 8A is configured to be easily attached to and detached from the drive ring 10 (or 107), for example, the mounting structure is the same as that of the above-described embodiment of FIG. 16, but this point is shown in FIGS. 22 is not shown. However, such a design change of the example of FIGS. 18 to 22 can be easily performed from the matters already described with reference to FIG. As in the above embodiments, the drive ring 10 (or 107) is attached to the support plate 12 (or 108) having the attachment plate 11 (or 111). Since the structure for driving the above structure and the holding frame 8A by the support plate 12 (or 108) is the same as that of each of the embodiments already described, the illustration is omitted in FIGS.
As shown in FIGS. 18, 19, 21, and 22, the receiving frame portion 301 has a cylindrical shape, and its tip is formed in an oblique shape. The receiving frame portion 301 has an opening in the upper portion, and a lighter hole for lightness is formed in the lower portion. A holding member 302 is fixed to the central portion on the back side of the opening of the receiving frame portion 301. The holding member 302 is a portion that extends to the opening and presses the center (back) center portion of the heel component V set with the front portion of the heel facing forward with respect to the receiving frame portion 301. As a result, the set heel member V is prevented from floating.
Two clamping mechanisms 303a and 303b are provided on both sides of the receiving frame portion 301 in order to grip the side portions of the saddle structure V at two locations. Since the clamp mechanisms 303a and 303b for each side have the same configuration, the same reference numerals are given for convenience, and only the clamp mechanisms 303a and 303b provided on one side will be described. In addition, the clamp mechanisms 303a and 303b provided on one side have substantially the same configuration even if the specific shapes are somewhat different. Therefore, only the clamp mechanism 303a closer to the front will be described in detail for convenience. The clamp mechanism 303a has a substrate 304a fixed to the receiving frame portion 301 so that the position can be adjusted, and a guide plate 305a is fixed to the tip of the substrate 304a. A support member 306a is fixed to the substrate 304a. On the support member 306a, a clamp member 308a including a clamping piece 307a that clamps the side portion of the saddle structure V with the guide plate 305a is pivotally supported by a shaft 309a. The shaft 309a is provided with a torsion spring 310a, and the clamp member 308a is urged in the rotational direction in which the clamping piece 307a contacts the guide plate 305a. One end of a wire 312 is connected to the clamp member 308a. When the wire 312 is moved by an operation of a lock lever 316 described later, the clamp member 308a guides the clamping piece 307a against the urging force of the torsion spring 310a. It is rotated in a direction away from the plate 305a. It should be noted that the front clamp mechanism 303a is formed so that the tips of the substrate 304a, the guide plate 305a, and the sandwiching piece 307a are slanted so as to correspond to the shape of the saddle structure V (the shape of the front portion of the collar). . The guide plate 305b of the clamp mechanism 303b on the rear side is provided with stoppers 311 for determining (or guiding) the positions of both ends of the base portion of the saddle structure V.
The other ends of the wires 312 (four wires in total) provided for each of the clamp mechanisms 303 a and 303 b are connected to the arm portion of the sliding member 313 provided at the lower portion of the receiving frame portion 301. A rod 314 is fitted into the sliding member 313, and the sliding member 313 can slide along the rod 314. The rod 314 is provided on the receiving frame portion 301 via a fixing member 315. On the fixing member 315, a lock lever 316 is installed so as to be switchable between two positions in a snap lock manner. The link arm 316 a of the lock lever 316 is engaged with an engagement recess of an engagement member 317 fixed to the sliding member 313. Accordingly, as shown in FIG. 21, when the lock lever 316 is raised to the back side, the sliding member 313 is located on the back side, and the clamp members 308a and 308b of the clamp mechanisms 303a and 303b are connected to the torsion spring 310a. , 310b, the clamping pieces 307a, 307b are positioned at the position where the collar member V is clamped by the guide plates 305a, 305b, that is, the clamping position, as shown in FIG. On the other hand, as shown in FIG. 22, when the lock lever 316 is laid down toward the front side, the sliding member 313 is moved forward by being pulled by the link arm 316a of the lock lever, and the biasing force of the torsion springs 310a and 310b As a result, the wire 312 is pulled and the clamp members 308a and 308b are rotated to the state shown in FIG. 20, and the clamp is released (becomes an unclamp position). In this state, even if a force acts in a direction to return the wire 312 by the urging force of the torsion springs 310a and 310b, the lock lever 316 is locked with respect to the movement in that direction. First, the unclamping position is maintained. On the other hand, if the lock lever 316 is manually rotated so as to be raised toward the back as described above, the lock can be easily released and the lock lever 316 can be switched to the clamp position described above.
A slider 319 is provided on the upper surface of the receiving frame portion 301 so as to be slidable in the front-rear direction by a guide member 318, and a presser arm 320 is fixed to the tip of the slider 319. The slider 319 is urged forward by a coil spring 321 provided between the end of the guide member 318. A ratchet gear 322 is provided on the upper surface of the slider 319, and a tip end of a ratchet lever 323 pivotally supported above the ratchet gear 322 is engaged with the ratchet gear 322. The spring member 324 fixed to the upper surface of the guide member 318 is for urging the tip of the ratchet lever 323 in a direction to engage with the ratchet gear 322. Pins 325 are erected in the vicinity of the left and right ends of the presser arm 320, and a presser tray 326 is provided on the pin 325 so as to freely move up and down. The presser plate 326 clamps the tip of the heel component V (the front end of the heel) with the guide portion 320a of the presser arm 320, and the presser plate 326 is urged downward by a coil spring (not shown). FIG. 22 shows a state in which the presser arm 320 is positioned closer to the front side, while FIG. 21 shows a state in which the presser arm 320 is positioned deeper than that. When the presser arm 320 is slid from the position shown in FIG. 22 to the position shown in FIG. 21 in order to hold the heel component V set on the receiving frame 301, the upper part of both pins 325 is pushed to the back side with a finger. . As a result, the presser arm 320 is slid together with the slider 319 while shifting the engagement position between the ratchet gear 322 and the tip of the ratchet lever 323. On the other hand, when the presser arm 320 is returned from the position of FIG. 21 to the position of FIG. 22, the ratchet lever 323 is rotated to release the engagement between the tip and the ratchet gear 322. As a result, the slider 319 is pulled by the coil spring 321 and returns to the position of FIG. 22 together with the presser arm 320.
What is necessary is just to perform in order of setting the collar structure V to the receiving frame part 301 of 8 A of holding frames shown in FIGS. 18-22 by the following procedure. First, as shown in FIG. 22, the lock lever 316 is laid on the front side to set the unclamp position, and the clamp members 308 a and 308 b of the clamp mechanisms 303 a and 303 b are set to the open positions (state shown in FIG. 20). The ratchet lever 323 is rotated to bring the presser arm 320 back to the front. Next, the bag structure V is received and set in the opening of the frame portion 301. At this time, the base center portion of the saddle structure V is inserted under the holding member 302, and the both ends of the root portion of the saddle structure V are set in a state of being in contact with the stopper 311 of the rear clamp mechanism 303b. To do. In this way, by bringing both ends of the base portion of the heel structure V into contact with the stoppers 311 on both sides, the heel structure V set forward can be set without inclination. Next, the presser arm 320 is slid to the back so that the tip of the heel component V is sandwiched between the guide portion 320 a of the presser arm 320 and the presser plate 326. Then, the lock lever 316 is raised to the back side to set the clamp position, and the clamp members 308a and 308b of the clamp mechanisms 303a and 303b are rotated in accordance with this, thereby holding the clamping pieces 307a and 307b of the clamp members 308a and 308b and the guide plates 305a and 305b. And sandwich both side portions of the heel component V. As a result, as shown in FIG. 21, the heel component V is firmly held by the holding frame 8A.
As described above, according to the embodiment shown in FIGS. 18 to 22, the stopper 311 for positioning both ends of the root portion of the heel structure V is provided with the direction in which the heel structure V made of the hat heel is set as the forward direction. Therefore, by setting both ends of the base portion of the saddle structure V in contact with the respective stoppers 311, the saddle structure V set forward can be easily set without inclination. Furthermore, when the presser arm 320 is slid in order to clamp the front end of the heel structure V, a force is applied in a direction in which both ends of the root portion of the heel structure V abut against the stopper 311, so There is an advantage that the saddle member V does not tilt in preparation.
In the embodiment shown in FIGS. 18 to 22, the sliding member 313 for rotating the clamp members 308a and 308b is moved by manual operation of the lock lever 316, but a drive source such as an air cylinder is provided. The sliding member 313 may be driven automatically. Similarly, the slide of the presser arm 320 (slider 319) may be automatically slid by a driving source such as an air cylinder.
In the embodiment shown in FIGS. 18 to 22, the three rollers 15a to 15c (FIG. 19) that support the inner peripheral surface of the drive ring 10 perform the same function as the roller 15 shown in FIG. However, in this embodiment, the upper two rollers 15a and 15b are of a shape extending long forward unlike the roller 15 shown in FIG. The inner peripheral surface of the frame 301 is supported to guide the rotation of the receiving frame 301 (FIG. 18). Thereby, there exists an advantage that rotation of the receiving frame part 301 comes to be stabilized more.
The holding frame 8A configured according to the embodiment shown in FIGS. 18 to 22 or appropriately modified based on the embodiment is not limited to the case of being applied to the heel structure V composed of the hat heel. Needless to say, the present invention can be applied to other appropriate sewing structures V as appropriate.
