Abstract

The method involves movably arranging a device for knitting decoration materials of a spangle-or soutache supply device at a machine frame, and moving the device from a resting position into a sticking position in which a drive wheel of the device stays in engagement with a stationary drive shaft for coupling the device with a drive unit. The knitting device is moved from the sticking position into the resting position for decoupling the device from the drive unit, where the drive wheel is externally engaged with the stationary drive shaft in the resting position. An independent claim is also included for a device for knitting decoration materials of a spangle-or soutache supply device.

Description

The invention relates to a method for operating a device for holding decorative materials according to the preamble of claim 1, as well as a device for holding decorative materials according to the preamble of claim 4.

State of the art

Devices for embroidering decorative materials have been around for a hundred years. In the literature, a distinction is made between so-called soutache and pearl and bauble embroidery. In the Soutachestickerei cord or band-shaped material is embroidered in the desired decorative form on the embroidery floor. Pearl and bauble embroidery is about embroidering small objects, such as sequins, beads and the like ( Schöner, Freier, Stickereitechniken, Leipzig, 1982, p. 309, 329 . FR 467 481 . CH 563 486 ).

From the prior art, for example, from the EP-A 1 561 849 so-called sequin heads and from the EP-A 1 764 435 so-called soutache heads known, which are used in Schiffli embroidery machines. With these devices, tape-like parts can be supplied to an embroidery point and sewn on the embroidery base, wherein a band is separated with contiguous sequins when embroidering into individual sequins. A freshly separated sequin is already penetrated by a needle and is immediately embroidered with a few stitches.

From the prior art is also the EP 1 764 434 known, which describes and claims a particular aspect of the above-mentioned heads. According to the EP 1 764 434 Each sequin and Soutachekopf has an actuatable by the needle ram coupling for engaging the devices and a return device for disengaging the devices. The restoring device comprises a cylinder / piston unit, by means of which over the entire length of the machine extending shift rod can be actuated. The shift rod has at each Sequin resp. Soutachekopf a gripper, which disengages the sequin head on actuation of the return device. If a sequin resp. Soutachekopf turned off by the clutch wheel is disengaged from the drive shaft, a tooth engages the clutch wheel to block it. This has the advantage that the sequin tape is held in the position from which then the feed to be embroidered sequin is brought to the embroidery at a feed.

The from the EP 1 764 434 known devices are stationary on a support, that is not pivotable, arranged on the embroidery machine frame. To turn on a sequin or Soutachekopfs only one coupling wheel is pivoted, the remaining parts of the devices are not moved. A peculiarity of the devices described is that the sequin head is not driven directly, but via the coupling described. Another special feature is that to turn on a sequin resp. Soutachekopfes no separate actuator is necessary, as this is caused by the needle plunger.

Since the devices described above are not suitable for use with small-size knitting machines, in particular multi-head embroidery machines, it is an object of the present invention to propose a device for holding decorative materials, such as sequins, cords, cords, strands, bead cords and similar materials, which can be individually switched on and off. Another object is to propose a device which is inexpensive to manufacture. The device should also be retrofittable to existing embroidery machines. Another object is to propose a device by means of which simultaneously different sequins or sequins and a string can be embroidered on a stick bottom. Yet another goal is to propose a device by means of which several sequins can be stitched on top of each other. The aim is also to propose a corresponding method for operating a device.

This object is solved by the subject matters of the independent claims.

Advantageous embodiments will become apparent from the features of the dependent claims.

According to the invention, in a method according to the preamble of claim 1 for coupling with a drive unit, the whole apparatus for holding decorating materials is moved from a rest position to an embroidering position in which a drive wheel of the device with the stationary drive unit, for example, a drive shaft, engages. For decoupling in turn, the device is preferably moved by the same actuator from the embroidery position to the rest position in which the drive wheel is out of engagement with the stationary drive unit or drive shaft. The method according to the invention has the advantage that the devices for holding decorative materials can be individually and simply coupled to a drive shaft. Another advantage is that the accessibility of the needle site is not significantly limited by the attachment of the device to the embroidery machine because it is removed from the needle site when not in use. This in contrast to the sequin and Soutacheköpfen the above-mentioned EP-A-1 764 435 , which are fixed stationary on the machine frame.

Advantageously, the device is pivoted from the rest position to an embroidering position, and vice versa. A pivoting movement can be realized by a corresponding articulated coupling of the device on the embroidery machine frame in a simple way. In this case, the drive wheel can be determined in the rest position to prevent it from moving on in an uncontrolled manner.

The subject of the present invention is also an apparatus for holding decorative materials, such as a sequin ribbon and / or a cord. Such a device has a chassis or support profile on which a transport mechanism or gear for the transport of the decorative material is arranged. A drive member of the transmission or transport mechanism can be coupled to a drive shaft of an embroidery, sewing or quilting machine.

According to the invention, the device is equipped with an actuator. The device is designed or prepared to set the support profile in different positions, namely an embroidery near working position and an embroidery remote position, the machine frame. For this purpose, the device has fastening means which on the one hand connect the actuator and on the other hand the support profile with the embroidery head or embroidery machine frame. This means that the device can be connected to the machine frame by means of first fastening means acting on the actuator and second fastening means acting on the supporting profile. In this case, preferably by the first fastening means a rigid (fixed) Connected to the machine frame and preferably realized by the second fastening means a movable connection with the machine position. As a result, when the actuator is actuated-this does not change its position relative to the machine frame-the device is moved from a rest position to an embroidering position, in which the drive wheel is coupled to a stationary drive shaft provided on the embroidery, sewing or quilting machine. Conversely, in the second operation of the same actuator, the device can be moved away from the drive shaft. This is another difference to the devices of the EP-A-1 764 435 where the actuator is used only for decoupling the sequin and Soutacheköpfe and the coupling is done by the needle plunger. In contrast to EP-A-1 764 435 the axes of rotation of the individual drive gears and drive wheels are stationary relative to the support profile and not positionally changeable. The inventive device can be arranged to save space, for example, laterally on the embroidery head of a multi-head embroidery machine.

The fastening means are advantageously realized by a fastening device arranged on the actuator and a pivot lever which can be arranged on the support profile. This is a simple and inexpensive construction to achieve a local displacement of the whole device. Instead of a pivot lever but could also be used a stationary lever on which the support profile is slidably disposed. That is, it is conceivable within the scope of the present invention to arrange the devices for holding decorating materials by a combination of fastening and guiding means on the machine frame, so that the devices is movable from a rest position to an embroidery position, and vice versa.

An advantageous embodiment provides that the actuator is a piston / cylinder unit, that the fastening device is arranged on the cylinder of the piston / cylinder unit, and the piston engages the support profile. This makes it possible to effect a displacement of the support profile by an actuation of the actuator when the cylinder is fixedly arranged relative to the machine frame.

The inventive device is equipped with at least one sequin device or a Soutachevorrichtung. Preferably, however, according to another independent aspect of the invention, two devices for holding decorative materials, such as a sequin ribbon and / or a cord arranged on the mounting profile. Thus, either a sequin device and a Soutachevorrichtung or two sequin devices may be provided on one and the same support profile. In the case of the presence of two sequin devices, two guide channels are provided for the sequin bands, which are arranged one above the other. This has the great advantage that two sequins can be embroidered at the same time. The aufzufichenden sequins can be different in appearance and / or size.

Advantageously, a movable locking member is provided on the device, which blocks the transmission in the rest position of the device, and releases in the embroidery position. By the locking member of the transport mechanism can be locked in a defined position. Conveniently, the locking member is biased by a spring element in the locking position. This makes it possible to move or pivot the locking member by cooperating with a stationary stop. This stop can be mounted on the embroidery machine and arranged so that when moving the device into the embroidery position, the locking member is automatically moved.

A special feature of the Soutachevorrichtung is that this has a Soutacherad with a radial opening. This makes it possible to connect and disconnect the Soutachevorrichtung without the upper resp. Needle thread would have to be cut. So that the Soutacherad can be driven, the same is equipped on the periphery with a toothing and drivable by two spaced apart auxiliary gears. These auxiliary gears can in turn be driven by a central gear.

For cutting the cords and cords, a movable knife is preferably arranged on the Soutachevorrichtung, which is actuated by an actuator arranged on the support profile, for example a compressed air cylinder. Advantageously, a clamping spring is arranged on the Soutachevorrichtung, by means of which a cord can be clamped after cutting. Preferably, the clamping spring is actuated by the knife. An advantageous embodiment provides that the clamping spring is arranged on the underside of the Soutachekopfs and actuated by a cam arranged on the knife.

The subject matter of the present invention is also an embroidery sewing or quilting machine, in particular a multi-head embroidery machine, with a machine frame and a device arranged on the machine frame for holding decorative material. In this case, the device is preferably arranged pivotably about an axis of rotation on the machine frame. Alternatively, however, the device could be arranged linearly displaceable. This would require corresponding guide means between the mounting profile and the support profile and an actuator, e.g. Stepper motor, be provided to move the support profile.

Conveniently, a drive shaft is provided, which extends parallel to the row of needles. This drive shaft may be formed in one piece or composed of several sub-segments. Advantageously, a support profile for the device is provided, which is preferably releasably attached to the machine frame. In this case, the drive shaft can be accommodated in bearing sleeves, which are embedded in the mounting plate.

The inventive device for holding decorative material is particularly suitable for equipping a multi-head embroidery machine. In this case, one or two devices for holding decorative materials can be arranged per embroidery head. These can each be arranged laterally on the embroidery head. The positioning of the devices is such that they can be pivoted by means of a pivoting movement directly to the respective outermost needle point of the embroidery head.

The present invention generally relates to a device for embroidering decorative materials, which can be present, for example, as sequins and / or cords. The device for embroidering decorative materials can be arranged on an embroidery or sewing machine, in particular on a multi-head embroidery machine.

In FIG. 1 an embroidery head 11 of a multi-head embroidery machine is shown. Such multi-head embroidery machines are characterized by the fact that per embroidery head 11 a plurality of needle locations 13 are present, of which one individual is driven during operation. Such an embroidery head can therefore also be referred to as a multi-needle embroidery head. Each needle point 13 comprises a large thread guide 15, various other thread guiding devices 17, a needle plunger 19 which can be moved up and down, and a needle 21 which is detachably fastened to the needle plunger 19. According to the exemplary embodiment shown, a total of six needle points 13 (numbered 1 to 6) are provided, the third needle point being in operation from the right, ie active. To change the active needle point of the embroidery head 11 can be moved laterally in the direction of arrow 22 to couple another needle point with a drive, not shown. The working principle of these multi-head embroidery machines is well known to the person skilled in the art and therefore need not be explained in more detail here. The side of the embroidery head 11 is a device 23 for feeding decorative materials in the form of sequin tapes 24 (FIG. FIG. 7 shown).

How the next FIGS. 2a and 3a can be removed, the device 23 comprises a support profile 25, on which an actuator 27 is arranged. In the present case, the actuator 27 consists of a piston / cylinder unit with a piston 29 and a cylinder 31 (FIG. Fig. 3 ). The piston 29 is screwed with its front end on the support section 25 ( Fig. 3c : Screws 33). The cylinder 31 in turn is arranged stationary on the embroidery head 11 or embroidery machine frame. For this purpose, as shown in the present embodiment, a mounting plate 35 is provided on the embroidery head 11, on which the cylinder 31 is arranged ( Fig. 2c and Fig. 3c ). The mounting plate 35 has an arm 37 projecting at an angle, at the end of which a clamping device 39 is provided. The clamping device 39 has a preferably circular receptacle 41, in which a bolt 43 is rotatably received ( Fig. 2c and 3c ). The bolt 43 is detected by means of a clamping screw 45 against axial slipping out. The bolt 43 belongs to a clamping ring 47, which surrounds the cylinder 31 and clamps. By the bolt 43, a first pivot point 49 is defined (= axis of rotation).

A second articulation point 51 is given by a pivoting lever 53, which articulates the embroidery head 11 at a distance from the axis of rotation 57 with the support profile 25. The pivot lever 53 is pivotally mounted on an extension 55 of the mounting plate 35 (axis of rotation 57). Due to the described, articulated mounting of the device 23 on the embroidery machine by means of the switching member 27, a pivoting of the device 23 from a rest position ( Fig. 2 ) in an embroidery position ( Fig. 3 ) and vice versa. In this case, the support profile 25 is pivoted with the components mounted thereto by the actuator 27 about the axis of rotation 57.

A particular feature of the device 23 is that two different sequin belts can be processed simultaneously. Accordingly, two shoots for the transport of the sequin tapes are available. Each drive comprises a respective drive gearwheel 59a, 59b for driving one respective worm wheel 61a, 61b (FIG. Fig. 2a and 3c and Fig. 3a and 3c ). The drive gears 59a, 59b are coupled to first drive wheels 63a, 63b, and the warp wheels 61a, 61b are coupled to second drive wheels 65a, 65b. In this case, the first and second drive wheels 63a, 63b, 65a, 65b in each case via a toothed belt 67a, 67b with each other, so that about the drive gears 59a, 59b, the Warzenräder 61a, 61b can be driven.

To drive the drive gears 59a, 59b extend in the longitudinal direction of the embroidery machine, a first and a second rack 69a, 69b. The racks 69a, 69b are rotatably received in bushings 71a, 71b of the mounting plates 35 ( Fig. 2c and 3c ). The racks 69a, 69b are drivable by central drive units, not shown, in accordance with the specifications of an embroidery program stored in a control unit of the embroidery machine. In the in FIG. 3 shown position of the devices 23 are the drive gears 59a, 59b into engagement with the racks 69a, 69b. Instead of racks but also waves could be used with attached gears.

In order to prevent an unintentional adjustment of the drive gears 59a, 59b in the passive position of the device 11, locking levers 73a, 73b are arranged pivotably on the carrier profile 25 (best seen in FIGS Fig. 2a, 2c . Fig. 3c and Fig. 4 ). The locking levers 73a, 73b are biased by means of at least one spring 77 against the gears 59a, 59b and can engage with terminal locking cams 75a, 75b in the drive gears 59a, 59b ( Fig. 1a and 1c ). The locking lever 73 a, 73 b are fastened to a lever 79, which in turn is pivotally mounted on the support section 25. When pivoting the device 23 in the embroidery position of the lever 79 comes with one end into abutment with a stationary pin 81, whereby the lever 79 and the locking levers 73a, 73b arranged thereon are pivoted and out of engagement with the teeth of the drive gears 59a, 59b arrive ( Fig. 4 ). The stationary pin 81 is secured to the mounting plate 35, but could also be supported on the embroidery machine frame.

For exact positioning of the device 23 in the embroidery position, an adjustable alignment pin 83 is provided on the support profile 25 ( Fig. 2c . Fig. 3c and Fig. 4 ). The adjusting pin 83 has a screw thread at one end and is screwed into a threaded bore of a bearing 84. A lock nut 86 allows the detection of the adjusting pin 83 in a once set position. With the free end of the adjusting pin 83 is supported in the embroidery position of the device 23 on the pivot lever 53 from ( Fig. 2c and Fig. 4 ). With the help of the adjusting pin 83, the pivotal position of the device can be adjusted relative to the embroidery head, so that the opening of an ejected sequin is positioned exactly in the axis of the needle movable up and down. This is from Meaning for a smooth embroidery operation. Otherwise, there is a risk that the needle 21 hits the paillette and breaks.

Like from the FIGS. 2a and 3a it can be seen, the warts are 61a, 61b successively, but offset in height by a small distance from each other, rotatably mounted on the support section 25. Each warp wheel 61a, 61b is assigned a guide element 85a, 85b, which is prestressed against an associated warp wheel 61a, 61b and in operation presses the sequin belts against the warp wheels 61a, 61b. The position of the guide elements 85a, 85b may be generated by spring or other force means, such as magnets. The guide elements 85a, 85b are preferably pivotable about axes of rotation 87a, 87b in order to facilitate the threading of the sequin bands on the warts 61a, 61b ( Fig. 2a and 3a ). Directly adjacent to the guide elements 85a, 85b are guide channels 89a, 89b. The guide channels 89a, 89b have outlet openings 90a, 90b, which lie directly above one another. By this construction, it is possible through the guide channels 89a, 89b different, in particular different sized sequins supply the embroidery point and at the same time to embroider. In contrast to other known sequin devices so 2 different sequins can be issued and fixed by means of a stitch on the embroidery ground, so that both sequins are arranged one above the other.

The sequin bands (in the Figures 2 and 3 not shown) can be fed through feed channels 93a, 93b, which are fixed to the support profile 25, the cam followers 61a, 61b ( Fig. 2a and 3a ).

In the FIG. 4 shown alternative embodiment of a device for embroidering decorative materials allows the simultaneous feeding and embroidering of sequins and ribbons or cords: In other words, the apparatus comprises a sequin and a Soutachevorrichtung by means of which simultaneously sequins and bands (or cords) can be supplied. This alternative device is basically the same structure as the device described above according to the Figures 2 and 3 , but with the difference that a sequin feeder is replaced by a Soutachevorrichtung.

The drive for the Soutachevorrichtung can be largely the same design as the one the sequin device. In this case, however, the drive wheel 65a is coupled to a first bevel gear 91 instead of a cam wheel. The first bevel gear 91 cooperates with a second bevel gear 93, which is connected via a shaft 95 with a gear 97. The gear 97 engages in the toothing of two auxiliary gears 99, which in turn cooperate with a provided on the circumference of a Soutacherads 101 102 teeth. The Soutacherad 101 has an opening 103, which allows the device 23 to pivot from the embroidery position to the rest position without the needle thread would have to be cut off. The Soutacherad is rotatably mounted in a support 105 ( Fig. 5 ). The Soutacherad has in a known manner a hole 107 through which a string to be embroidered can be performed. Due to the two auxiliary gears 99, the toothing of the Soutacherads 101 remains independent of its rotational position permanently connected to the drive train.

Like from the Fig. 6 The exit opening 90b of the guide channel 89b is positioned so that the central opening of an entire sequin 104 (FIG. Fig. 7 ) is located substantially in the middle of the Soutacherads 101. The combination of a soutache device with a sequin device has the advantage that both cords and sequins, even one above the other, can be embroidered.

Laterally on the support 105, in which the Soutacherad 101 is mounted, a movable knife 109 is provided. This consists of a lever on which a cutting edge 111 is formed. The knife 109 is pivotally mounted on the support 105 (axis of rotation 106 in FIG Fig. 6 ) and can be pivoted by means of an individual drive 113, for example a pneumatic cylinder. For this purpose, the knife 109 is connected by means of a lever 110 with the piston rod 112 of the drive 113 in connection. Another stationary cutting edge 115 is formed on the lower edge of the support 105. The cutting edges 111,115 perform a scissor-like cutting movement during the operation of the knife 109.

On the underside of the support 105, a clamping spring 117, made for example of a spring steel, provided (s. FIGS. 5 to 8 ). The clamping spring 117 extends substantially parallel and adjacent to the knife 109. A cam 119 projecting from the knife 109 abuts the top of the clamp spring 117 and releases the spring when the knife 109 is opened ( Fig.7 and 8 ). When the knife 109 is closed, the clamping spring 117 rests against the underside of the support 105. In this position, she can clamp the end of a projecting out of the Soutacherad 101 cord or a band.

To cut a string, the knife 109 is first opened by the knife drive is actuated. At the same time, the clamping spring 117 opens, since the cam 119 entrains the clamping spring. Then, the embroidery frame with the embroidered embroidery ground is moved so that the between the Soutacherad and the embroidery base extending cord piece between the movable and the stationary cutting edges 111, 115 comes to rest. Once this is the case, the drive 113 can in turn be actuated and the blade 109 closed. When closing the knife 109, the cord is clamped by the clamping spring 117 on the underside of the support 105 and then cut.

In summary, therefore, it can be appreciated that the method of operating a decorating material holding device 23, such as a sequin or soutache feeding device, provides that the entire device is moved from a rest position to an embroidering position relative to the embroidery machine for coupling to a drive unit of an embroidery machine in which a drive wheel of the device engages a stationary drive shaft and for decoupling, the device is moved from the embroidering position to the rest position in which the drive wheel is out of engagement with the stationary drive shaft. An exemplary device 23 for carrying out the method is equipped with an actuator 27, for example a piston / cylinder unit. In this case, a part of the piston / cylinder unit is attached to a support profile 25. Fastening means 43, 53 for fastening the device to an embroidery or sewing machine engage on the one hand on the other part of the piston / cylinder assembly and on the other hand on the support profile 25, so that upon actuation of the actuator (27) the device is movable from a rest position to an embroidery position, in which the drive wheel is coupled to a stationary drive shaft provided on the embroidery, sewing or quilting machine.
