Multi-head embroidery machine

A multi-head embroidery machine according to the citation of claim 1 of the present invention.

By Fried Sch Ner and Klaus Freier's book "Embroidery Technology" (VEB Science and Technology Press, Leipzig, 1982, 1st edition), embroidery machines can be classified according to different points of view: the first classification is for the number of line systems involved in the embroidery process: In the case of some machines, embroidery is only produced with a one-line system. Other machines require two line systems, that is, another second line is required: the lower line, the rear line, the line axis, the shuttle line, or the yarn tube line (Bobinenfaden, English) :bobbin thread).

The second classification is for the number of needles that work simultaneously: examples of single needle embroidery machines are Singer, Adler and crank embroidery machines. The multi-needle or Rapport embroidery machine (Rapportstickmaschine) is a shuttle type embroidery machine and a hand embroidery machine.

In addition to these two groups, there are also multi-head embroidery machines, which are not in the above two groups. The principle of this machine is to install 3, 4, 6, 10 or 12 Singer embroidery heads onto a large platen. These embroidery heads are driven by a common drive shaft. It is necessary for the synchronized operation of the head thus achieved so that all the needles are simultaneously pierced into the embroidery base cloth (Stickboden, English: embryo ground) or simultaneously from the embroidery base cloth. Here, for each head, the embroidery base fabric can be individually sandwiched in an embroidery frame (Stickrahmen, English: embroidery frame). These embroidery frames are screwed to a structure like a creel, which is controlled in the horizontal plane by a small automatic device (Antomat). In an embroidery robot with six heads, the embroidery field area is approximately 240 x 240 mm. The components for forming the embroidery and the procedure for forming the embroidery are the same as those of the Singer embroidery machine, and the only difference from the latter is that a cloth presser is provided in each of the above, which holds the embroidery base fabric firmly in the embroidery. If the embroidery frame moves further, the presser is often raised. In addition, individual embroidery heads typically have a line monitoring system that automatically turns off the machine when the line is broken.

The first batch of multi-head embroidery machines was sold by De Singer Sewing Machine Factory 100 years ago (see The Art of Embroidery, Coleman, Schneider, 1991). The first automatic multi-head embroidery machine was launched in 1927 (also known as "W "rker-Automat") For further literature, see the general textbook "Technology and Production Engineering" Klaus Freier, VEB Science Press, Yebir, 130~131.

The present invention relates to the above-described multi-head embroidery sewing machine in which each of the embroidery heads is provided with a plurality of needle positions. Hereinafter, in order to clearly distinguish them in the specification, the multi-head embroidery sewing machine is also referred to as a "multi-head multi-needle embroidery machine". Here, in general, each needle position has a line monitor (optional), a wire guide (also referred to as a wire take-up bar in the literature), and a wire guiding device, which includes a wire tensioning device for compensating the stitch. Position (for the line), and a needle on the needle (Nadelst) The needle on the ssel, English: needle tappet, which can move up and down and be driven by a drive unit. The above-described elements forming the stitches are also referred to as "online unit" as a whole in the specification. The embroidery head of the multi-head embroidery machine is supported on a carrier arm and can be moved laterally. Below the embroidery heads, there is a stitch board (needle board), and a pinhole is provided in the stitch board for inserting a needle, and the stitch board defines the position of the embroidery position. Each of the needles of an embroidery head can move laterally to the embroidery position, and in operation, the embroidery base fabric (which is stretched over a tent frame movable in the x and y directions) rests on the embroidery position . The needles in the embroidered position pass through the embroidered base fabric into the pinholes as the needle moves. Here, the upper thread passes through the embroidered base fabric and a loop is formed on the back side of the embroidered base fabric by means of the associated needle movement (Schlauf, loop:). Then go offline through this loop. When the needle is pulled back, the upper thread is pulled and a so-called stitch (stitch, stitch) is formed in the embroidery base fabric (Stich, English: stitch). When embroidering, only one of the needle positions is active, that is, the needle position at the embroidery position. The embroidery head of the above-described multi-head embroidery machine is disposed in a specific ratio along the arm in a conventional manner.

Therefore, one of the characteristics of these multi-head multi-needle embroidery sewing machines is that each embroidery head has a plurality of needle positions. This has the advantage that another line can be placed at each needle position, so that multi-color embroidery can be done, and often only the relevant needle is in motion.

The needle tappet of a needle set and its associated wire rod are generally supported in a carrier which, by movement, brings the selected needle bar and each of its associated wire rods to a positionally fixed manner The front of the drive is to replace the line.

For example, a conventional multi-head multi-needle embroidery sewing machine is shown in FIGS. 1 and 2, which comprises a frame (201), an embroidery table (203) provided on the frame (201), and a plurality of embroidery heads ( 205) [They are arranged in a row above the embroidery table], as shown in Fig. 2, each of the embroidery heads (205) has a plurality of needle positions each having a needle (215). Here, each needle position comprises a fixed line guide element (207) or a line brake. An up and down line take-up lever or wire guide (209), and a wire steering member (211), and a needle (215) [the needle is disposed on a needle (213) having a needle tappet (214) (Nadelkreb) on]. As further shown in Fig. 2, each of the needle tappets (214) is provided with a presser (217), and an embroidery frame (219) is provided below the embroidery head (205), and the embroidery base fabric to be embroidered can be stretched on the embroidery In the box. The embroidery table (203) can be placed in a large tenter frame (221) that extends over the width of the embroidery table (203). The tenter frame (221) can be moved in the x and y directions in a conventional manner. As described above, the embroidery head is disposed on a linear guide (223) and is movable along the guide in the x direction.

For example, the conventional multi-needle multi-needle embroidery machine has the disadvantage that the pressure applicator is directly disposed on the needle tappet, so that it is coupled with the movement of the needle tappet (cannot be unhooked), and another disadvantage is that each needle requires a separate presser. .

In US 2007/0261621 a multi-head embroidery machine is disclosed in which each embroidery head has only one presser foot. Here, the presser foot, the needle bar and the large wire guide are each driven by a separate motor. Another motor is used to move the needle bar housing laterally along a guide rail, each coupling a certain needle position to the driver.

The presser is placed on a rod that can be vertically moved by a guide. The two positioning elements are fixed at a distance from each other on the rod in a central section. A connecting member is disposed between the two positioning members, and is disposed on the rod. The connecting member is coupled to the shaft of the press driving motor by a connecting arm and a "drive rod". A roller is provided on one of the positioning elements and is embedded in a guiding groove of the guiding portion. The guiding groove has an upper guiding section and a lower straight guiding section which are connected to each other by means of a slanted guiding section. During the sewing operation, the roller moves up and down in synchronization with the needle drive in the lower guiding section. Here, a pinhole of the applicator foot is exactly positioned above the pinhole of a pin plate.

To change the needle, the drive shaft of the drive motor is rotated for a period of time, so that the roller is moved to the end of the upper guide section via the oblique guide section. Thus, the rod rotates (the presser is placed on the rod) so that the pinhole of the presser foot and the pinhole of the stitch plate are separated by a distance.

German publication DE-OS-10 2008 004855 discloses a device in which the presser of a multi-head embroidery machine is raised. Here, the apparatus includes a "drive cam" disposed on a drive shaft that cooperates with a transmission member to produce the latter's vibratory motion. The driving component is pivotally connected to a first end of a "driving lever", the driving lever is rotatable about a turning point, and the second end of the driving lever is pivotally connected to a driving block member, and the driving block member can be guided along The rod moves vertically. The drive block guides a "connector". The connection holder is fitted in a shape-fitting manner with a "driver holder". The drive holder can be guided in axial movement on a needle tappet. A presser drive shaft is disposed on the drive holder parallel to the needle guide shaft and separated by a small distance. There is also a presser foot height adjuster to move the point of rotation of the presser drive lever so that the height of the presser foot can be adjusted.

In particular, it can be seen from German Patent Publication DE-OS-10 2008 012 846 [which is a further development of the embroidery machine of DE-OS-10 2008 004855] that a spring is provided between the drive block and the connection holder, which Apply the joint pre-stress to the joint. As such, the force of the presser against the pin plate can be limited. Furthermore, the embodiment of DE-OS-10 2008 012 846 is characterized in that the needle bar and the presser foot are all operated by means of a further drive mechanism. This has the advantage that the path of the presser foot can be freely generated, so that the stroke or lower end of the presser foot can be freely produced. The disadvantage is that complicated control is required to synchronize individual drivers, and a disadvantage is that a large number of motors are required for each needle position, the number of which is equivalent to the number of needle positions. This makes the above-mentioned embroidery machine not only expensive, but also often repaired.

SUMMARY OF THE INVENTION An object of the present invention is to provide a multi-head multi-needle embroidering machine which has absolutely no such disadvantages, and in particular has an object to provide a multi-head multi-needle embroidering machine. It is more efficient than traditional machines. Another object is to provide a machine in which the cloth can be independently moved without being affected by the movement of the needle tappet. A further object is to provide an embroidery machine whose drive is strong and inexpensive to manufacture.

The present invention relates to a multi-head embroidery machine. It has at least one embroidery head with a plurality of needle positions. The needle position is located on a carrier and is movable in the x direction (i.e., lateral direction) relative to an embroidery position. Each needle position includes components such as a wire guide, a wire guide, and a needle tappet (one of which can be attached thereto), and the needle lifter reciprocates in the z direction. The above components are also collectively referred to as an upper line unit. There is a lower line unit that mates with each embroidery head. A tenter is provided between the upper unit and the lower unit to set up an embroidery. The tenter has two first and second cloth holding members spaced apart in the y direction.

As is generally known, a multi-head embroidery machine has an actuator (e.g., having a central drive shaft) to drive the upper and lower wire units in synchronism.

In an embroidery machine according to the citation of the first paragraph of the patent application, this object is achieved according to the invention in that the coupler of the presser unit is driven by a common presser drive shaft. This has the advantage that it can be synchronized with the needle movement. As with the need to use individual motors, the drive can be manufactured inexpensively. Here, the motor of the main drive shaft of the embroidery machine can also be used to drive the drive shaft of the presser by coupling the main drive shaft to the drive shaft of the press. The main drive shaft and the drive shaft of the press should extend over the entire length of the embroidery machine.

The same drive shaft should be used for the driving action of the needle tappet and the press (and the driving action of the large conductor). In this way, the manufacturing cost can be further reduced. For the driving of the needle tappet and the use of a coupler for the large wire guide, it will be described in the following description of the presser.

In an advantageous manner, the axially movable applicator is arranged at a distance from a needle fixed to the needle tappet. Therefore, unlike the prior art, in a multi-needle embroidering machine, the presser is no longer directly placed on the needle tappet, but is defined as a separately driven unit that is completely separate from the needle driver. This has the advantage that each embroidery head requires only a presser. Another advantage is that the presser is no longer directly coupled to the movement of the needle tappet. There is another big advantage to this: the presser does not have to be shaped according to the movement of the needle, and can even contain a motion model that is completely his own. Therefore, the multi-needle embroidering machine of the present invention, which is constructed on the Singer embroidery sewing machine which has been conventionally known for decades, is based on a completely new concept. Since the distance of the applicator from the needle is larger than in the prior art, the stitch formation procedure is not obstructed. In the conventional embroidery machine described above, the cloth press is very close to the needle. Generally, the distance between the needle and the presser is between 2 and 4 mm. This means that the maximum stitch length is limited to a distance of 2 to 4 mm. Otherwise, especially when the stitches are formed, the upper thread will be caught between the presser and the stitch plate, which will cause the wire to break.

The presser unit preferably comprises a presser pusher, and the presser finger is preferably releasably secured thereto, wherein the presser finger is located at a distance from a needle disposed on the needle lifter Distance. Here, the distance of the applicator finger from the needle is preferably greater than 5 mm, and preferably greater than 10 mm, particularly preferably 12 mm or more.

Each of the presser units is preferably driven by a separate actuator. This has the advantage that it is not necessary to exercise a larger mass. In an advantageous embodiment, the presser unit can be driven using a common drive shaft. This has the advantage that it is relatively simple to synchronize with the needle movement. The drive shaft can be placed on the carrier and extends over the entire length of the machine. Furthermore, the driver of the presser unit can be coupled to the central drive shaft.

The pusher unit can be driven separately by a different actuator than the needle drive unit. To drive the presser unit, conventionally known actuators of different designs, such as a coupling or curved coupling, can be used. According to an embodiment, the coupler includes a pivoting lever that pivots about a pivot axis and drives the presser unit. Such a pivoting lever is preferably provided on a shaft in a fixed position and in a non-rotatable manner. To create a vibrating motion, use a curved disc, an eccentric, a cam, and the like. One solution is to use a coupler with a curved disk that converts the rotational motion of the drive shaft into a reciprocating motion of the presser. If this is not the case, the coupler can have a lever mechanism and an eccentric link to create a reciprocating motion of the presser. An inexpensive solution is to couple the drive shaft for generating the vibratory motion to the main drive shaft of the embroidery machine. This can be achieved with a toothed belt, chain or other means. In this way, the cloth press moves in full synchronism with the needle driver.

According to a preferred embodiment, the applicator is pivotally attached to a first end of the pivoting lever and the coupler is fitted to the second end thereof.

This is a simple and reliable construction which can be manufactured inexpensively. Preferably, a first continuous portion and a second continuous portion are provided on the second end of the pivoting lever at a distance from each other. The first and second continuations are disposed on opposite sides of a plane that passes through a pivot axis of the pivoting lever and a rotational axis of the drive shaft. Here, a first eccentric is embedded in the first continuous portion to generate a movement of the pivoting lever in one direction, and a second eccentric is embedded in a second eccentric to generate the pivoting lever in the opposite direction. motion. Such an embodiment allows the pivoting lever to vibrate virtually without play. Preferably, the applicator includes a presser pusher having a first end pivotally coupled to the first end of the pivoting lever and a presser finger secured to the second end thereof. This can be inexpensively manufactured from steel sheets using deformation techniques.

Preferably, the applicator member is coated with plastic at its portion in contact with the cloth. This has the advantage that on the one hand, a thin and easily damaged cloth can be processed, and on the other hand, a good attachment to a common cloth can be achieved. Preferably, the presser fingers are configured to move axially relative to the presser tappet. This has the advantage that differently high embroidery and/or different thick cloths can be held firmly. Unlike conventional multi-head multi-needle embroidering machines (one of which is placed on each needle tappet and can be moved laterally). The presser is placed on the embroidery machine in a positionally fixed manner, that is, it does not move laterally. Even though substantially only one embroidery head having a plurality of needle positions can be provided, in the preferred embodiment, a plurality of embroidery heads are provided on the carrier rail in a laterally movable manner. Here, another needle position is selected to move the embroidery head laterally relative to a drive member until the needle position is engageable with the drive member.

As is known in the art, an embroidery frame is provided, and the driver forming the components of the pins is preferably provided in a positionally fixed manner. Here, the embroidery head having a plurality of needle positions can be moved laterally with respect to the driver. It is best to have a large number of embroidery heads.

An embodiment of the multi-head multi-needle embroidering machine of the present invention will be described below with reference to the drawings.

The presser unit (11) shown in the drawing mainly comprises a presser (13) which is movable up and down in the axial direction, and a coupler (15) which is used to generate the movement of the presser. The presser (13) is composed of a presser tappet (17), a compensating link (19) is pivotally connected at its first end, and a presser finger (21) is releasably secured thereto. On its second end. The presser tappet (17) is guided in such a manner as to be axially movable by means of one or several bearings or guide sleeves not shown.

The presser finger (21) has a lower section (22). It has a flattened foot (23) which rests on the embroidery during operation of the embroidery machine and at the bottom dead center of the press (see Figures 3 and 5). An upper section (24) of the applicator finger (21) is designed in a U-shape and is intended to be attached to the presser tappet (17). A recess (29) (31) is provided in the mutually parallel legs (25) (27) of the U-shaped section through which the second end of the presser tappet (17) can extend. The presser finger (21) is releasably secured to the presser tappet (17) by a clamping block (35). The clamping block (35) is fixed to the presser tappet (17) by a fixing screw (37).

The presser finger (12) is held in the elongated hole by a pin (31) projecting by the clamping block (35) so that it does not rotate. The pin (33) projects through an elongated hole (35) in the base leg of the U-shaped section of the applicator finger. The longitudinal extent of the elongated hole limits the maximum path of the pusher finger (21) relative to the presser tappet (17). There is a spring (28) [which is placed on the presser tappet (17) between the clamping block (35) and the leg (25)] to press the leg (25) down and pull the leg (27) To the stop portion (26), the stop portion is preferably made of a cushioning material. For example, a plastic underpad can be used as the stop (26). The plastic material for the stopper (26) may be an elastomer. By making the fabric finger (21) elastic and flexible, on the one hand, the embroidery of different heights can be firmly held on the embroidery board under the cloth embroidery, and the thickness can be different. The cloth is firmly held on the embroidery board.

This foot (23) is provided on the leg (25) of the applicator finger (21) by means of a joint (28). The foot (23) is designed in the form of a flat reclining plate, preferably of a generally rectangular shape, which extends substantially parallel to the legs (25) (27) and is preferably aligned with the legs (25) (27). Unlike the conventional presser foot, the presser here has no gaps or openings for the needle to pass because it is located at a large distance from the needle.

The axial length extension [arrow (39)] of the coupler (15) for generating the motion of the presser includes a pivot lever (43) pivotable about a pivot axis (41), the pivot lever The first end of (43) is pivotally connected to the presser (13) or the compensating link (19) (Fig. 3). A first continuous portion (45) and a second continuous portion (47) are formed on the second end of the pivoting lever (43), and a first roller (49) is rotatably supported on the pivoting lever ( 43) On the first end, the roller is engageable with a first cam (51) of the coupler (15), and a second roller (53) is rotatably supported in the second continuous portion (47) Upper, the roller cooperates with a second cam (55) of the coupler (15). An eccentric curved trajectory is defined around the two cams (51) (55). These curved trajectories are designed such that when the cam (51) (55) is rotated one turn, the pivot lever (43) is engaged by the cam (51) (55) and the roller (49) (53) to guide the gapless manner. Progress. This is achieved by positioning a curved roller (cam) on a slightly eccentric pin and rotating the pin until the pivoting lever runs in a play-free manner. The cam (51) (55) is disposed on a drive shaft (59) in a relatively non-rotatable manner, and the drive shaft (59) is rotatable about a rotary shaft (57). This drive shaft (57) is used to drive all of the fabrics of the multi-head embroidery machine of the present invention. For example, instead of a peripherally curved disc cam (Kurvenscheibe), another conventional motion conversion mechanism can be used, which converts the rotational motion of a drive shaft into a vibrating motion of a stitch-forming component such as a press. For example, it can be a stereoscopic cam (Nocken) having an endless cam slot or track that is disposed on the drive shaft in a relatively non-rotatable manner. A cam pusher is guided in the cam track, which converts the rotational motion of the drive shaft into a reciprocating motion.

Figure 6 shows a perspective partial view of an embroidery head (61). This view shows the needle at the bottom dead center where the stitches form motion. The illustrated embroidery head (61) has a total of six needle positions (63), each of which is provided with a large wire guide (65), some wire guiding devices (67) and a needle tappet (70). The needle (69) on it, as can be seen in the figure, each embroidery head (61) is provided with only a single presser (13), and the presser is fixed in position (ie, cannot move laterally) It is placed on a carrier (71). A (and preferably several) guides (73) (only one shown in Fig. 6) are provided on the carrier (71), and the embroidery head (61) having the needle position is movable along the guide rails. In other words, the embroidery head (61) is designed in the form of a carriage that is movably supported on the guide member (73). The carrier (71) is placed in a positionally fixed manner on an embroidery frame (72) (not shown).

A stitching plate (75) is provided under the embroidery head (61), and an embroidery base cloth is placed on the stitching plate (75) during embroidery. The pin plate (75) has a pinhole (77) which guides the needle thread through the pinhole (77) to the back of the embroidered base fabric. There is a distance a between the needle (69) and the foot (21) of the cloth which is greater than 5 mm, and preferably greater than 8 mm, and more preferably greater than 12 mm.

To select a particular needle position for the embroidery process, the embroidery head (61) is moved relative to the carrier (71) all the way to the needle position where the desired line is positioned in front of a drive member (not shown). In this position, the drive element is coupled to the needle tappet so that a rotating drive shaft and an associated coupler can be used to cause the vibrating motion of the needle tappet. Unlike the needle driver, the presser pusher can be permanently coupled. On the drive.

An embroidery machine (especially a multi-needle embroidery machine) has at least one embroidery head provided on a carrier (71) having a plurality of needle positions (63). These needle positions (63) are arranged in such a manner that they can be moved along the side edge carrier (71) in a moving direction with respect to an embroidery position. Each needle position (63) contains all of the major stitch forming elements as defined, such as a wire guide (65), a different wire guide (67), and a needle disposed on a needle lifter (70). . The needle tappet (70) and the needle (69) disposed thereon can each be moved back and forth in the first direction by a needle drive unit. Each of the lower line units cooperates with each of the embroidery heads, and the lower line unit provides a lower line. A coupler (72) disposed on a frame (72) is used to synchronize the movement of the upper wire unit with the stitch forming member of the lower wire unit. The multi-needle embroidering machine is characterized in that at least one presser unit (11) is provided on each of the embroidery heads on the frame (72), and has an axially movable presser (13) disposed at a distance from the needle The tappet (70) is at a distance.
