Device for presenting decorative materials and method for operating the same

The present invention relates to a method for operating a device for presenting a decorative material according to the preamble of claim 1 and a device for presenting a decorative material according to item 4 of the patent application.

Devices for embroidery with decorative materials have been available for nearly a hundred years. In the technical literature, there is a difference between the so-called sash embroidery and the beaded embroidery glitter embroidery. In sash embroidery, a string or ribbon-like material is sewn to the embroidery base in the desired decorative form. For beaded embroidered glitter embroidery, small objects such as beads, beads and the like are sewn up (Schöner, Freier, Embroidery Techniques, Leipzig, 1982, p. 309, 329, FR 467 481, CH 563 486) .

From the prior art, for example, EP-A 1 561 849 discloses a so-called bead head, and EP-A 1 764 435 discloses a garnish head in which a shuttle embroidery machine is used. With these devices, strip-like components are supplied to the embroidery dots and sewn to the embroidery base, wherein when stitched in place, a strip of joined beads is separated into individual beads. The newly separated beads have been pierced by the needles and are therefore firmly attached with new stitches.

The prior art also includes EP 1 764 434, which describes and claims a particular aspect of the above mentioned head. According to EP 1 764 434, each bead and the sash head have a connector and a resetting device which can be activated by a needle stalk for coupling into the device, the reset The device is then used to separate the device. The reset device contains a cylinder/piston An assembly by means of which a connecting rod extending the entire length of the machine can be operated. For each bead or sash head, the connecting bar has a grip that unlocks the bead head when the resetting device is operated. When the bead or sash head is disengaged and the splicing wheel does not engage the drive shaft, one tooth will engage the splicing wheel to block the splicing wheel. This has the advantage that the bead strip can be securely held in place from which the sewn pieces can be brought into the correct position for the stitching during advancement.

The device known from EP 1 764 434 is mounted in a stationary manner, i.e., cannot be rotated on a carrier on the frame of the embroidery machine. In order to snap the beads or the sash head, the connecting wheels are only rotated, and the other parts of the device cannot move. A feature of the described device is that the bead head is not driven directly, but rather is driven by the connector. Another feature is that it is not necessary to have separate actuators to engage the beads or the sash head, since the snap-on beads or the sash head are achieved by the needle stalks.

Since the device described above is not suitable for use on a small embroidery machine, particularly on a multi-head embroidery machine, it is an object of the invention to provide a device for presenting decorative materials, such as can be individually joined Or detached beads, braids, strings, ribbons, stringed beads, and similar materials. Another project is to propose a device that is economical to manufacture. Such a device can also be mounted on an existing embroidery machine. Another project is to propose a device by means of which different beads or beads and The string can be sewn to the embroidery base at the same time. Another item is to propose a device by means of which a plurality of beads can be sewn to each other. It is an object of the invention to further propose a corresponding method for operating the aforementioned device.

This project was achieved by means of the target area of the patent application scope of the independent item. Advantageous embodiments can be derived from the features of the scope of the patent application.

According to the invention, in the method according to the preamble of claim 1, in order to be combined with a drive unit, the entire device for presenting the decorative material is moved from a rest position to an embroidery position, wherein a drive wheel of the device It becomes into engagement with a stationary drive unit, such as a drive shaft. For re-separation, it is preferred to use the same actuator that moves from the embroidered position to the rest position in which the drive wheel is disengaged from the stationary drive unit or the drive shaft. The method according to the invention has the advantage that the means for presenting the decorative material can be individually and easily integrated into a drive shaft. Another advantage is that the accessibility of the needle position is substantially unrestricted by the attachment of the device to the embroidery machine because the device is removed from the needle position when not in use. This is in contrast to the sequins and sash heads of the EP-A 1 764 435 which are fixed in a fixed manner to the machine frame.

Advantageously, the device can be rotated from a rest position to an embroidery position and vice versa. The rotational movement can be easily achieved by pivotally coupling the device to the embroidery machine frame accordingly. Here the drive wheel can be fixed in a rest position to prevent it from moving further without being controlled.

The subject matter of the present invention is also a method for presenting, for example, a sequin strip and/or a string. The device of decorative materials. Such a device has a chassis or carrier profile, and a transport mechanism or gear assembly for transporting the decorative material is disposed on the chassis or carrier profile. A gear assembly or a drive member of the transport mechanism can be combined with an embroidery machine, a sewing machine or a drive shaft of the lining machine.

According to the invention, the device is fitted with an actuator. The device is designed or prepared to establish a carrier profile at different locations on the machine frame, i.e., a working position near the embroidery point and a rest position away from the embroidery point. For this purpose, the device has a securing mechanism that first connects the actuator to the embroidery head or the embroidery machine frame and secondly connects the carrier contour to the embroidery head or the embroidery machine frame. This means that the device can be first connected to the machine frame by means of a first fastening mechanism acting on the actuator and by means of a second fastening mechanism acting on the contour of the carrier. Preferably, the first securing mechanism creates a rigid (fixed) connection to the machine frame, and preferably the second securing mechanism creates a mobile connection to the machine frame. Thus when the actuator is activated - the actuator does not change its position relative to the machine frame - the device moves from the rest position to the embroidery position, in which the drive train is mounted on the embroidery machine, A combination of a sewing machine or a fixed drive shaft on a cotton lining machine. Conversely, when the same actuator is repeatedly activated, the device moves away from the drive shaft. This is another difference from the device of EP-A 1 764 435. In the device of EP-A 1 764 435, the actuator is only used to separate the beads and the band head from the connector and to effect the joining action. It happens through the needle weaving. In contrast to EP-A 1 764 435, the individual drive gears and the axis of rotation of the drive wheels are It is stationary relative to the carrier profile and cannot change position. The device according to the invention can be configured to be very compact, for example arranged on the side of the embroidery head of the multi-head embroidery machine.

Advantageously, the securing mechanism is implemented by a securing device disposed on the actuator and a rotating lever disposed on the contour of the carrier. This is a simple and low cost construction for achieving local variations in the overall device. However, instead of using a rotating lever, a fixed lever can also be used, the carrier profile being mounted on the fixed lever in a displaceable manner. This means that in the context of the present invention, it is conceivable to arrange the device for presenting the decorative material on the machine frame by means of a combination of fixing and guiding mechanisms, so that the device can be moved integrally from the rest position to the embroidery position, and vice versa.

An advantageous embodiment provides that the actuator is a piston/cylinder assembly that is configured on the cylinder of the piston/cylinder assembly and that acts on the carrier contour. As a result, with cylinders that are configured securely relative to the machine frame, it is possible to create displacement of the carrier profile by actuating the actuator.

The device according to the invention is equipped with at least one bead device or a soutache device. However, it is preferred that in accordance with another independent aspect of the present invention, two means for presenting a decorative material such as a bead strip and/or a string are disposed on the mounting contour. A bead device and a sash device or two bead devices can be placed on one and the same carrier profile. In the presence of two bead devices, two guiding channels for the bead strip, the guiding channels being configured such that one channel is on the other Fang, this has the great advantage that two beads can be sewn at the same time. The appearance and/or size of the beads to be sewn may be different.

Advantageously, a mobile locking element is provided on the device that blocks the gear assembly in the rest position of the device and releases the gear assembly in the embedding position. The locking element allows the transport mechanism to be locked in a predetermined position. Advantageously, the locking element is pretensioned in the locked position by the action of a spring element. This allows the locking element to be moved or rotated, wherein the locking element cooperates with a fixed stop. The stop can be mounted on the embroidery machine and configured such that when the device is moved into the embroidery position, the locking element can be automatically moved.

A feature of the sash device is that it has a garnish wheel with a radial opening. This allows the sash device to be incorporated or taken out without the upper thread or the needle thread that needs to be cut. In order to make it possible to drive the belt wheel, it is mounted with teeth on its circumference and can be driven by two separate auxiliary gears. These auxiliary gears can thus be driven by a central gear.

In order to cut the string and the braid, it is preferred to have a movable cutter disposed on the ribbon device, the cutter being configurable by an actuator disposed on the contour of the carrier, for example compression The air cylinder is moving. Advantageously, a clamping spring is disposed on the sash device and the string can be clamped by the clamping spring after cutting. Preferably, the clamping spring can be activated by the cutter. An advantageous embodiment provides that the clamping spring is disposed on the underside of the fascia head and can be provided by a projection disposed on the cutter start up.

The subject matter of the invention may also be an embroidery machine, a sewing machine or a cotton lining machine, in particular a multi-head embroidery machine, with a machine frame, and the device for presenting the decorative material according to the invention is arranged on the machine frame. The device is configured to be rotatable about a rotational axis on the machine frame. Alternatively, the device can be configured to be displaced in a straight line. For this purpose, a corresponding guiding mechanism can be provided between the mounting profile and the carrier profile and an actuator, such as a stepper motor, for moving the carrier profile.

Conveniently, there is a drive shaft extending parallel to the row of knitting needles. The drive shaft can be formed as one piece or from a plurality of component segments. It is advantageous to provide the device with a carrier profile that is preferably detachably secured to the machine frame. The drive shaft can be received in the bearing bushing into the mounting plate.

The device for presenting decorative materials according to the invention is particularly suitable for mounting on a multi-head embroidery machine. For each embroidery head, one or two means for presenting the decorative material may be provided. These devices can each be placed on the side of the embroidery head. The positioning of the device can be rotated by means of a rotary motion to the outermost needle position of the embroidery head.

The present invention is generally related to a device for embroidering a decorative material, such as in the form of a bead and/or wire. The means for stitching on the decorative material can be placed on an embroidery or sewing machine, in particular a multi-head embroidery machine.

Figure 1 shows an embroidery head 11 of a multi-head embroidery machine. This multi-head embroidery machine is characterized in that it is provided with a plurality of knitting needle positions 13 for each embroidery head 11, wherein only one single knitting needle position is driven in operation. This embroidery head can therefore be referred to as a multi-needle embroidery head. Each needle position 13 includes a large wire guide 15, various additional wire guiding devices 17, a needle needle lifter 19 that is movable upwardly and downwardly, and a woven fabric that is detachably secured to the needle lifter 19. Needle 21. According to an exemplary embodiment shown. There are a total of six knitting needle positions 13 (No. 1 to No. 6), in which the third knitting needle position from the right is in operation, that is, effective. In order to change the effective needle position, the embroidery head 11 can be moved to the side in the direction of the arrow 22 by a driver (not shown in detail) to engage another needle position. The working principle of such a multi-head embroidery machine is well known to those of ordinary skill in the art and need not be described in greater detail herein. The side of the embroidery head 11 is provided with a means 23 for feeding a decorative material formed in the form of a bead strip 24 (shown in Figure 7).

As further shown in Figures 2a and 3a, the device 23 includes a carrier profile 25 on which the actuator 27 is disposed. In this example, the actuator 27 is comprised of a piston/cylinder unit having a piston 29 and a cylinder 31 (Fig. 3). The piston 29 is securely screwed to the carrier profile 25 with its front end (Fig. 3c: screw 33). The cylinders 31 are sequentially and fixedly disposed on the embroidery head 11 or the embroidery machine frame. For this purpose, as shown in the exemplary embodiment, the embroidery head 11 is provided with a mounting plate member 35 which is disposed on the mounting plate member 35 (Fig. 2c and Fig. 3c). The mounting plate member 35 has an arm portion 37 that protrudes at an angle, the end of the arm portion The system is provided with a fixing device 39, which in one embodiment is a clamping device 39. The clamping device 39 preferably has a circular recess 41 in which a bolt 43 is rotatably held (Fig. 2c and Fig. 3c). The bolt 43 can be fixed to resist axial sliding by a clamping screw 45. The bolt 43 belongs to a clamping ring 47 which surrounds and clamps the cylinder 31. The bolt 43 defines a first pivot point 49 (corresponding to the axis of rotation).

A second pivot point 51 is given by a rotary lever 53 that connects the embroidery head 11 and pivots with the carrier profile 25 at a distance from the axis of rotation 57. The rotary lever 53 is configured to rotate on an extension portion 55 (rotation shaft 57) of the attachment plate member 35. Since the device 23 is pivotally mounted on the embroidery machine, by means of the switching element element 27, the device 23 can be rotated away from a rest position (Fig. 2) into an embroidery position (Fig. 3) and vice versa. The carrier profile 25 and the components mounted thereon are rotated by the actuator 27 about the axis of rotation 57.

One particular feature of the device 23 is that two different bead strips can operate simultaneously. Therefore, two drivers are provided for transporting the beads. Each drive has a drive element 59a, 59b. In one of the embodiments, the drive elements 59a, 59b are drive gears 59a, 59b for driving a lance wheel 61a, 61b (Figs. 2a and 2c, and Figs. 3a and 3c). The drive gears 59a, 59b are coupled to the first drive wheels 63a, 63b, and the lance wheels 61a, 61b are coupled to the second drive wheels 65a, 65b. The first and second drive wheels 63a, 63b, 65a, 65b are each coupled together via a toothed belt 67a, 67b such that the spurs 61a, 61b can be driven via the drive gears 59a, 59b move.

In order to drive the drive gears 59a, 59b, the drive shafts 69a, 69b extend in the longitudinal direction of the embroidery machine. In one embodiment, the drive shafts 69a, 69b are a first and second toothed member 69a. 69b. The toothed rod members 69a, 69b are rotatably held in the passages 71a, 71b of the mounting plate member 35 (Figs. 2c and 3c). The toothed bars 69a, 69b can be driven by a central drive unit (not shown) in accordance with the specifications of the embroidery program stored in a control unit of the embroidery machine. At the position of the device 23 shown in Fig. 3, the drive gears 59a, 59b are engaged with the toothed rod members 69a, 69b. However, instead of a toothed rod, a shaft with a mounted gear can be used.

In order to prevent unnecessary displacement of the drive gears 59a, 59b in the passive position of the device 11, the mobile locking elements 73a, 73b (best shown in Figures 2a, 2c, 3c and 4) are configured to be in the carrier The contour 25 is pivoted, and in one embodiment, the mobile locking elements 73a, 73b are locking levers 73a, 73b. The locking levers 73a, 73b are pretensioned against the gears 59a, 59b by at least one spring 77 and are engageable with locking cams 75a, 75b mounted at the ends in the drive gear (Figs. 1a and 1c). The locking levers 73a, 73b are fastened to a lever 79 which is in turn rotatably arranged on the carrier profile 25. When the device 23 is rotated to the embroidery position, the lever 79 is seated at one end thereof on a fixing pin 81, whereby the lever 79 and the locking levers 73a, 73b disposed thereon are rotated and moved away from the driving gears 59a, 59b. (Figure 4). The fixing pin 81 is fixed to the mounting plate member 35, but can also be supported on the embroidery machine frame.

In order to accurately position the device 23 in the embroidery position, an adjustable pin The 83 series is placed on the carrier profile 25 (Figs. 2c, 3c and 4). The adjustment pin 83 has a thread at one end thereof and is screwed into a screw hole of a bearing 84. A locking nut 86 allows the adjustment pin 83 to be secured once set. The adjustment pin 83 is parked with its free end on the rotary lever 53 in the embroidery position of the device 23 (Figs. 2c and 4). Using the adjustment pin 83, the rotational position of the device relative to the embroidery head can be adjusted such that the opening of the discharged bead is accurately positioned in the axis in which the needle moves up and down. This is important for smooth embroidery operations. Otherwise, there is a risk that the needle 21 will hit the bead and be destroyed.

As is apparent from Figures 2a and 3a, the lancet wheels 61a, 61b are rotatably disposed on the carrier profile 25, but are offset from each other by a slight distance in height. A guiding member 85a, 85b is assigned to each of the spurs 61a, 61b which is pre-tensioned against the assigned spurs 61a, 61b and which in operation operates the beads against the spurs 61a, 61b push down. The position of the guiding elements 85a, 85b can be generated by a spring or other force mechanism such as a magnet. The guiding elements 85a, 85b are preferably rotatable about the axes of rotation 87a, 87b to assist in the screwing of the bead strips to the stab wheels 61a, 61b (Figs. 2a and 3a). Directly adjacent to the guiding elements 85a, 85b are guiding channels 89a, 89b. The guide channels 89a, 89b have outlet openings 90a, 90b that are placed directly above each other. With this design, it is possible to guide the beads having different sizes through the guide passages 89a, 89b to the embroidery dots and simultaneously embroider the beads. Compared to other conventional bead devices, two different beads can be output and attached to the embroidery base by a stitching method, so that the two beads are placed on each other.

The bead strips (not shown in Figures 2 and 3) can be supplied to the lancet wheels 61a, 61b by feed channels 93a, 93b, and the feed channels 93a, 93b are attached to the carrier profile 25 (Fig. 2a and Figure 3a).

An alternative embodiment of the device for embroidering decorative materials shown in Figure 4 allows for simultaneous feeding and embroidery of the beads and ribbons or wires: in other words, the device comprises a bead device and a sash ( Soutache) devices, by which the beads or sashes (or ropes) can be fed simultaneously. This alternative device is constructed in principle similar to the device described in accordance with Figures 2 and 3, but with the difference that a bead feed device is replaced by a sash device.

The driver for the sash device can be formed primarily like the driver of the bead device. However, the drive wheel 65a is coupled to the first bevel gear 91 instead of the lance wheel. The first helical gear 91 cooperates with a second helical gear 93, and the second helical gear is coupled to the gear 97 via a shaft 95. The gear 97 engages the teeth of the two auxiliary gears 99, which in turn cooperate with the teeth 102 disposed on the periphery of a decorative wheel 101. The decor wheel 101 has an opening 103 that allows the device 23 to be rotated from the embroidered position to the rest position without the need to cut the needle thread. The belt pulley is rotatably mounted in a support member 105 (Fig. 5). In a conventional manner, the belt wheel method has a hole 107 through which a wire can be guided.

Because of the two auxiliary gears 99, the teeth of the belt pulley 101 remain permanently connected to the drive train regardless of their rotational position.

As is apparent from Fig. 6, the guide passage 89b for the bead strip is located below the support member 105. The outlet opening 90b of the guiding passage 89b is determined The central opening of a complete bead 104 that is fully protruded from the guide channel (Fig. 7) is positioned substantially in the center of the decor wheel 101. The combination of a ribbon device and a bead device has the advantage that both the wire and the beads can be embroidered and even embroidered to each other.

Mounted on the side of the support member 105 in which the trimming wheel 101 is mounted is a movable cutter 109. This includes a lever on which a cutting edge 111 is formed. The cutter 109 is rotatably mounted on the support member 105 (the rotating shaft 106 in FIG. 6) and is rotated by a further actuator 113. In one embodiment, the actuator 113 is Driver 113 (eg, a pneumatic cylinder). For this purpose, the cutter 109 is coupled to the piston rod member 112 of the actuator 113 via a lever 110. An additional fixed cutting edge 115 is formed below the support member 105. After the cutter 109 is activated, the cutting edges 111, 115 perform a scissor-like cutting motion.

A clamping spring 117 is attached to the bottom of the support member 105, and the clamping spring is made of, for example, spring steel (refer to Figs. 5 to 8). The clamping spring 117 extends substantially parallel to and adjacent the cutter 109. A nose piece 119 extending from the cutter 109 is placed on top of the clamp spring 117 and lifts the spring when the cutter 109 is open (Figs. 7 and 8). When the cutter 109 is closed, the clamping spring 117 is placed on the bottom of the support member 105. In this position, it can grip the wire protruding from the belt pulley 101 or the end of the ribbon.

To cut a wire, the first cutter 109 is opened with the cutter drive activated. The clamping spring 117 is simultaneously opened because the nose piece 119 carries the spring therewith. Subsequently, the embroidery frame with the clamped embroidery base is moved, thus extending between the belt pulley and the embroidery base The wire portion becomes parked on the moving and fixed cutting edges 111, 115. Once this is done, the drive 113 can be activated again and the cutter 109 is closed. When the cutter 109 is closed, the wire is clamped under the support member 105 by the clamp spring 117 and then cut.

In summary, the method for operating a device 23 (eg, a bead or ribbon feed device) that presents a decorative material provides a combination with a drive unit of the embroidery machine that moves from a rest position relative to the embroidery machine. An embroidery position in which a drive wheel of the device becomes engaged with a stationary drive shaft, and for separation, the device moves from the embroidery position to the rest position, wherein the drive wheel is separated from the stationary drive shaft. An example of a device 23 for carrying out the method is provided with an actuator 27, such as a piston/cylinder assembly. The portion of the piston/cylinder assembly is attached to a carrier profile 25. The securing mechanisms 43, 53 for securing the device to an embroidery or sewing machine first engage the rest of the piston/cylinder assembly and secondly engage the carrier profile 25 so that when the actuator 27 is activated, the device can be The rest position is moved to an embroidery position in which the drive train is coupled to a stationary drive shaft provided in an embroidery, sewing or quilting machine.
