The present invention provides a separate piece feed device for supplying an individual piece to a needle site of an embroidery machine, a quilting machine or a sewing machine according to the preamble of claim 1, and with such a device. A embroidery machine, a quilting or sewing machine, and a method for embroidering individual pieces according to the preamble of claim 13.

In the following description, it should be understood that the term "embroidery machine" means an embroidery machine, a quilting machine, a sewing machine and a small embroidery machine. The device is especially designed for a Shipley embroidery machine having a plurality of needles on a needle line. The device is, for example, a known type of device for embroidery machines for preparing sequins, laces and the like, and is capable of sewing pieces prepared by means such as needles and threads to the embroidery surface. To be.

According to the prior art, the so-called sequin heads are disclosed, for example, in EP 1 561 849. Here a decorative member, such as a sequin in the form of a curled ribbon, is supplied to the suture zone and sutured to the embroidery surface. In the meantime, in each case the topmost sequin is separated from the subsequent sequin during embroidery. The sequin head described above is characterized in that when the sequin to be embroidered is penetrated by the needle, it is separated from the ribbon.

According to the prior art, European Patent Publication No. 1 764 434 embroiders or quilters with ornament devices such as sequins or decorative heads with couplings operated by coupling needle tappets. Is disclosed. The jewelry device also has a restoring device controlled by a machine controller to separate the device.

Swiss patent 669 715 discloses a machine for applying a decorative member on a face. Such a machine has a device for discharging individual decorative members and a device for fixing each decorative member on a face. Herein, the fixing device is designed as an embroidery machine-sewing machine having at least one needle, for example in the form of an embroidery machine or a sewing machine. The apparatus for discharging the individual decorative member mentioned above has a device for supplying the decorative member at a position where the individual decorative member is separated from the subsequent decorative member, and a separate decorative member in a guide channel to the fixing device. A subsequent device for coming is provided. In the position accessible to the fixing device, in particular the needle, which is hereafter designated as an individual piece holder, the decorative member is fixed between the elastic tongue and the base of the guide channel. Semicircular notches are formed on both the distal end of the base and on the tongue. In the forward position, the sequin is secured between the tongue and the base of the guide channel such that half of the sequin protrudes from the feed device. The outer half of the sequin is engaged between the resilient tongue and the base of the guide channel, and the opening in the sequin is exposed by a semicircular notch so that the needle of the fastening device can penetrate the decorative member. After stitching the decorative member, the embroidery surface must move downward to guide the decorative member out of the semi-circular notch. A disadvantage of the device described above is that the embroidery surface must always move in a very specific direction, ie downward, in order to guide the decorative member out of the guide device. As a result, the relative movement between the device and the face after embroidering the decorative member is very limited.

Fabrics with embroidered sequins and ornamental surgery are very popular. There is a need to spread a wide variety of fabrics with embroidered individual pieces, and to produce more rich and colorful fabrics.

Accordingly, it is an object of the present invention to provide a method and apparatus by which individual pieces can be embroidered without the above limitations. In particular, it is aimed at being able to move the embroidery surface about all sides while embroidering on an individual piece. It is also an object to provide a feed device that can remain stationary during all embroidery processes.

The above object is achieved by the technical features of the independent claims. Preferred embodiments are proposed from the technical features of the dependent claims.

The individual piece feed device according to the invention corresponding to the independent claim 1 has the following technical features in the general features of the prior art according to Swiss patent 669 715. The individual piece feed device comprises a rear side which is preferably arranged parallel to the embroidery surface when the device is mounted to the embroidery machine-sewing machine. In addition, a separate piece holder is provided for holding the individual pieces in place and embroidering them on an embroidery surface, ie fabric, using an embroidery-sewing machine. The device may comprise a magazine or a connection point for attaching the magazine. The magazine has a space for receiving a plurality of individual pieces to be embroidered. The individual piece holder is designed to hold one individual piece in place. The feed mechanism is designed to move the individual pieces present in the magazine into the individual piece holders or along the feed path to the individual piece holders, for example using a conveying action by a tappet. In the scope of the present invention, it is to be understood that the term "embroidery machine" also means sewing machines, quilting machines and small embroidery machines. Correspondingly, the term "embroidery surface" means "sewing surface" when the device according to the invention is used in connection with a sewing machine.

According to the invention, the individual piece holder has a discharge opening for the individual piece, the axis of the discharge opening extending substantially parallel to the direction of movement of the needle. Unlike the prior art, the individual piece holder of the device has an outlet for the individual piece facing the rear side of the feed device. That is, the individual pieces are not laterally discharged from the individual piece holder but deviate in the axial direction of the discharge opening. Here, when the individual piece feed device is mounted on the sewing machine or the embroidery machine, the side opposite to the embroidery surface forms the rear side of the original device. On the other side, the front side, a mechanism is provided, for example, a punch, for providing reciprocating motion. The outlet has a discharge opening defining a discharge direction of the individual piece, the direction being formed substantially perpendicular to the rear side of the individual piece feed device. Thus, the individual pieces are preferably laterally fixed to the individual piece holders in at least two or three positions, and falling off from the individual piece holders on the front side is suitably prevented. In contrast, the rear face of the base plate with guide tracks for attaching the individual pieces is provided with passages for the individual pieces. The individual pieces are secured laterally to the individual piece holder so that the individual pieces are properly prevented from falling off by a cover covering the side spaced apart from the embroidery surface. The individual pieces embroidered can have substantially any geometric shape, and generally their width or diameter is considerably greater than their height. Preferably the individual pieces have a flat base area which abuts on the embroidery surface during substantially embroidering. The diameter of the outlet opening corresponds to the diameter of the flat individual piece of embroidery. The diameter of the outlet corresponds to the diameter of a flat single piece embroidered on the embroidery surface.

According to the device of the invention, as soon as the individual pieces are sewn on the needles, they can exit the individual piece holders in the direction of movement of the needles and can be sewn onto the embroidery surface using a first suture. Compared with the prior art first mentioned, there is no need to move the embroidery surface to remove the individual pieces from the feed device. This saves time. The feed path is also designed as a guide channel having a substantially rectangular cross section. The outlets are arranged parallel to the sides of the individual piece holders.

In the device according to the invention, the head can be arranged away from the sewing or embroidery surface. By this, the individual pieces already embroidered can be located between the sewing or embroidery surface and the individual piece holder. Since the individual pieces have already left the individual piece holders, the sewing or embroidery surface for the head is given a degree of freedom for immediate movement after the first fixed suture.

According to a preferred embodiment of the present invention, blocking or clamping means are provided at the end of the feed path to detachably secure the most individual piece in the feed path. This configuration has the advantage that the individual pieces do not slide automatically into the individual piece holders. Thus, it is possible to continue the normal sewing or embroidery process without removing the feed device from the needle path immediately after the individual piece has been sewn. In contrast to the conventional apparatus, the feed apparatus can be placed in a stationary state on the sewing machine or the embroidery machine during the entire embroidery operation. Blocking or clamping means are arranged so that the individual pieces housed in the individual piece holders are preferably further secured.

Preferably, additional lateral or other directional fixing means are provided in the individual piece holders or in the individual piece holders for securing the individual pieces. The fastening means can be used depending on the shape of the individual piece. The fastening means may comprise at least one clamping or fastening member for enabling the fastening of the individual pieces in the correct position within the individual piece holder. Preferably the securing means is formed by a movable slider located at the outlet in the forward position and ejected from the outlet in the reverse position. According to this embodiment, there is an advantage that the individual pieces do not fall away from the individual piece holders. This makes it possible to escape the outlet opening only after the individual pieces have been penetrated by the needle. Preferably the slider has a fork shaped end to allow the needle to be penetrated through the individual piece holder without being disturbed.

During embroidering, the individual pieces can be pulled out of the individual piece holder by pulling the thread. However, preferably the apparatus is equipped with an ejector in order to separate the individual pieces from the individual piece holders. The ejector may be formed on the needle or placed on a needle tappet of a sewing or embroidery machine to push the individual piece located in the individual piece holder to the outlet using movement of the needle in the discharge direction. Thus, while the first fixed suture is performed, the individual pieces have already left the individual piece holder so that the subsequent fixed sutures can be performed completely freely in that direction and length.

Preferably the head adjusts to secure the individual pieces in a ready state. This adjustment ensures that each individual piece of embroidery is fixed to an individual piece holder, and the holes formed in the individual pieces or the penetrable positions formed in the individual pieces are arranged in position so that they are arranged parallel to the discharge direction and the direction of movement of the needle. Thus, the individual pieces are circular and not only have a central hole like the sequins, but can also be fixed separately to the embroidery surface, such as, for example, covered buttons that can be sewn. After embroidering, the individual pieces may be tilted 90 ° so that the holes provided therein may lie parallel to the embroidery surface, and the surface of the individual pieces may lie approximately parallel to the embroidery surface.

In each case, the individual piece holder is preferably provided with a limit stop so that the individual piece is exactly positioned where the needle of the embroidery machine strikes the hole or the penetrating position. The blocking member is provided at the front end of the individual piece holder when viewed in the transport direction. During the process, the resistant member is configured such that the individual pieces can be fixed in the correct position. Preferably, the resistant member is constituted by partially circular segments positioned to face each other. As a result, the individual pieces are accurately fixed to the individual piece holders and can be pushed out of the individual piece holders in the direction of movement of the needle, rather than falling away from the individual piece holders.

In order to keep the movement of the feed mechanism as short as possible, and to keep the space required for the device small in the area of the needle, the feed mechanism can stop the transport operation at a constant distance from the individual piece holder, which distance is preferred. Preferably corresponding to the dimensions of one or more individual pieces, preferably corresponding to the dimensions of three individual pieces. In other words, multiple individual pieces may be present in the feed path and may be transported together in the feed mechanism. According to this configuration, the individual pieces at the foremost of the pieces with respect to the position of the feed mechanism can be placed in the individual piece holders, or just in front of the individual piece holders, and can be pushed into the individual piece holders as the next piece. The feed mechanism with the stop surface is adjacent to the individual piece furthest from the farthest individual piece of the pieces in the feed path. In addition, individual pieces naturally lie in the magazine. However, one of these subsequent individual pieces enters the feed path as the individual pieces in the feed path are pushed forward and the feed mechanism releases the feed path.

In addition, the clamping device, which allows the individual pieces to be fixed at an external position of the individual piece holder, is preferably in the feed path. Such a device ensures that the best individual piece does not fall from the individual piece holder before the feed mechanism is activated. Such a clamping device may be formed by the above-mentioned clamping portion of the individual piece holder or other clamping device.

If the clamping device is formed independently from the additional clamping portion of the individual piece holder, the clamping device preferably has a spring member, for example a flexible tongue, that narrows the feed path. Such a flexible tongue narrows the feed path, for example in a direction parallel to the discharge direction, thus squeezing the individual pieces against the base or cover of the feed path. However, the spring means may also be coupled to the lateral direction of the feed path or feed channel.

In contrast, the clamping portions of the individual piece holders are formed in the same plane and are formed by two resilient, opposing tongues or jaws that narrow the recessed portion of the distal individual piece holder perpendicularly to the discharge direction. Thereby, the individual pieces are fixed towards the sides of the individual piece holders, and there are no mechanical parts disposed between the individual pieces and the outlet or blocking the outlet.

The tongue of the clamping portion preferably has a blocking surface, which is arranged in contact with the periphery of the individual pieces in order to place the piece on the blocking surface. If necessary, in order to obtain a large blocking surface, the blocking surface may be curved to correspond to the perimeter.

The feed device preferably comprises a guide device for the individual piece. Such a guide device can form a feed path and a magazine. Such a guide device is preferably formed of three layers, an intermediate layer defining at least partially a guide track that matches the dimensions of the base, the individual piece and the individual piece holder corresponding to the outlet, and at least partially covering and partially covering the guide track. A cover layer or cover that closes the individual piece holder on the front side. The cover and the intermediate layer or the base and the intermediate layer can be joined, and the guide track and the individual piece holder must recess into the channel shape from this joined layer. In the case of having separate intermediate layers, the width and height of the transport track can be defined without changing the dimensions of the cover or base layer. Preferably, the different layers can each be formed by a single plate punched or laser processed of the steel sheet.

Preferably the flexible tongue is formed separately from the individual piece holder in the cover. Also, in the cover, in at least one area of the individual piece holder, the recess is formed so as to be accessible solely at the individual piece of the sewing machine or the embroidery machine.

Preferably the feed mechanism comprises a tappet or punch. The feed mechanism moves the punch back and forth to transport the individual pieces in the feed path in the direction of the distal individual piece holder. This punch is preferably at least partially engaged with the feed path and is preferably guided to an intermediate layer between the lid and the base layer. According to this embodiment, the magazine is integrated in the base plate.

The feed mechanism may have its own drive means. However, the feed mechanism may preferably be designed to be connected to the drive means in the embroidery machine and may be designed to be detachable from the drive means. By this, all connected feed devices can be controlled by one control command transmitted from the embroidery machine. Preferably the shut off operation takes place in a known manner using a mechanism to shut down all devices. The connection is preferably made in a known manner using the movement of the needle or needle tappet.

Preferably a side opening is provided in the individual piece holder in addition to the rear opening. Thereby, the needle thread of the embroidery position does not need to be pulled through the individual piece holder for each suture, so that the embroidery surface does not bend against the individual piece holder while the embroidery surface is moving and no longer loosen. This has the significant advantage that the needle thread does not need to be cut as a result. The resistant member of the individual piece holder is preferably two jaws. This allows the individual piece holder to be formed open between the two jaws of the resistant member.

Ejectors can be formed in different ways. For example, it may be formed by a shoulder formed or disposed on a shaft or a needle. Shoulders formed on the needles require specially manufactured needles. Therefore, it is preferable to arrange the shoulder on the needle. Substantially the diameter of the shoulder or the dimension of the portion at least perpendicular to the needle direction is smaller than the diameter of the individual piece being ejected and larger than the diameter of the hole formed or punched by the needle in the individual piece. A cost-effective ejector is a sleeve that can be attached onto a needle. The shoulder is formed by a sleeve attached to the shaft of the needle. Such a sleeve may be a piece cut from a tube. In addition, the ejector may be formed to be disposed separately from the needle in the needle tappet. Preferably, the ejector has a length shorter than at least the thickness of the individual piece, less than the distance from the embroidery surface to the top needle tappet. The lengths are preferably shorter, placed on top of each other and applied to the embroidery surface, so that the stone, appliqued fabric requiring a very large offset between the advancing tappet and the embroidery surface. ), Allow redundancy to be formed for new sutures and the like. The pulling in of the individual pieces until the individual pieces are placed on the embroidery surface is achieved by tightening the needle thread and the reciprocating thread.

In the embroidery machine, the shoulder is preferably formed on the needle for discharging the individual pieces in the individual piece holder of the head out of the individual piece holder.

Connection portions for magazine connection may be provided on the base plate and the front side of the guide track. Preferably the magazine can be integrated at least partially into the base plate.

Preferably, the feed mechanism is designed to be coupled to the drive means of the embroidery machine and is detachable from the drive means. This configuration is for example made using a corresponding coupling device for coupling the actuator to the drive means by the coupling device means.

It is an object of the present invention to provide an embroidery machine, sewing machine or quilting machine having at least one individual piece feed device according to the invention. Embroidery machines, sewing machines or quilters having such a device, more particularly, the Shipley embroidery machine, include needle lines with at least one needle or a plurality of needles, tension-holding devices and needles for embroidery backgrounds, in particular frames; And a controller for controlling the movement of the tension-holding device. The drive means for the needle and tension-holding device are controlled and adjusted by the controller. A drive means for the above-mentioned device or the feed mechanism of the device is provided, the drive means being controlled by the controller.

In the embroidery machine mounted in this way, in contrast to the button feed device for the sewing machine, the head is disposed on its rear side away from the plane of the embroidery base to allow movement of the embroidery base and the piece embroidered thereon.

The machine controller is also designed to adjust the insertion of the individual pieces into the individual piece holder by means of a feed mechanism for the movement of the needle. Thus, the feed mechanism only works when the individual pieces are sewn. Between the step of embroidering the individual pieces and the step of embroidering the next individual piece, the embroidery machine can make a plurality of sutures at this embroidery position. During the time between the steps of embroidering two individual pieces, there are no individual pieces in the individual piece holder and the feed mechanism remains stationary.

The present invention also relates to a method of embroidering individual pieces by means of an embroidery machine, in particular a Shipley embroidery machine means. The method is characterized in that a single, loose individual piece is introduced into an individual piece holder, the individual piece is fixed in a ready state in the individual piece holder, and the individual piece in the ready state is penetrated by a needle through the hole in the individual piece. , A known step of embroidering on the embroidery ground using needles and threads. In contrast to the first described Swiss patent 669 715, a new step is that the individual pieces move from the individual piece holders to the embroidery base and are placed on the needle.

A preferred embodiment of the method includes the step of discharging the individual pieces from the individual piece holders by the shoulders involved in the movement of the needle tappet. If a slider is provided in the feed device, the individual pieces are ejected only after the slider has retracted. In addition, the method is improved such that the moment of insertion of the individual pieces into the individual piece holder is adjusted by the stroke of the movement of the needle tappet, and the backward of the slider has the effect of embodied with the movement of the needle, On the one hand, the slider is preferably improved to have the effect of moving backwards fast enough to avoid collision with the needle, no matter how late.

In short, the present invention provides that the individual piece is penetrated by the needle end and sewed on the needle, moved from the individual piece holder according to the direction of movement of the needle, and the head of the head in the correct position arranged with the needle of the embroidery machine to move towards the embroidery surface. It can be said to be fixed to the individual piece holder ready. To achieve this, the head has a separate piece holder in which the individual pieces can be ejected solely to one side of the device, ie towards the embroidery base.

The invention is explained in more detail using the drawings.

The exemplary embodiment described below is designed to be driven by a drive means of a sewing machine or an embroidery machine. The drive means is driven using a shaft 3 with a gear or splined shaft (FIG. 4). The shaft 3 extends over the entire length or part of the length of the embroidery machine and can be rotated in one direction or the other by a motor (not shown).

In order to turn the drive means on or off, a switching mechanism or coupling device is provided in the individual piece feed device according to the invention, for example as disclosed in EP 1 764 434. The content of EP 1 764 434 is incorporated by reference in this detailed description. Such conventional switching mechanisms not included in the present invention allow for example a sequin head or a decorative surgical head connected by a needle tappet.

The practical configuration of the feed mechanism 13 of the feed device according to the invention is the feed path 17 and the punch 35 which act as actuators for the transport of the individual pieces 30 in the feed path (FIG. 1). The punch 35 is hinged to a slad 39 which can be driven by the lever 37. The lever 37 is connected to the shaft 157 and rotatably fixed. Gear 153 is disposed on shaft 157 and is rotatably fixed, and can be aligned to engage pivot coupling wheel 151 (FIG. 4). The gear 153 can be driven through the coupling wheel 151 using the spline shaft 3 (FIG. 4). The coupling wheel 151 can rotate about the axis 29 of the gear 153, so that it can be aligned to engage the spline shaft 3 in the first pivot position and then not to engage in the second pivot position. To be installed. A more detailed description of the coupling process is given in the description of FIG. 17 below.

The head 11 shown in FIGS. 1 to 4 may be arranged on an installation rail 5 which preferably extends over the length of the embroidery machine (FIG. 4). For this purpose, a positioning pin 21 and a fixing screw 23 or fixing hole are provided in the fixing plate 20 of the head 11. By this, the head 11 can be located at any embroidery position of the sewing machine or the Shipley embroidery machine, and can be driven using the spline shaft 3. According to a preferred embodiment, the mounting rails 5 can be shifted or rotated so as to allow unobstructed access to the needle position.

According to the embodiment shown in FIGS. 1 and 2, the head 11 has a magazine 15 for an individual piece 30 that is open. In the illustrated embodiment, the individual pieces are, for example, rhinestones of the Swarovski compony of Wattens, Austria, which are specially embroidered. However, the individual pieces may be simple plastic pieces, thick squins or other decorative pieces. Also, for example, transceiver and / or ski lift subscriptions for light reflectors or avalanche survey devices, RFID chips, photovoltaic cells, electronic devices, contact fields, GSM antennas, and other It may also be a technical piece, such as a microelectronic component. The magazine 15 is connected to the upper side of the feed path 17. The individual piece holder 19 is provided behind the feed path 17.

The head 11 has a guide track 50 arranged in a position which is mounted on a machine in a substantially vertical or vertical plane (FIG. 1). In the upper region, this guide track 50 forms a magazine 15. The magazine-part of the guide track 50 leads to the tappet or punch 35 of the feed mechanism 13. During operation, this punch 35 moves up and down from the first reverse position to the second forward position and repeats. In the outward movement, the punch 35 delivers the individual pieces 30 separated from the magazine 15 into the feed path 17 in the direction of the individual piece holder 19 (FIG. 2). Here, the stroke movement of the punch 35 corresponds approximately to the diameter of the individual piece. In the advanced position, the punch 35 blocks access to the feed path 17 (FIG. 12). In the regression movement, the punch 35 opens the access to the feed path 17 (FIG. 11). Thereby, the next individual piece 30 from the magazine 15 can be introduced into the feed path 17.

The guide track 30 (FIG. 3) is formed in the base plate 51. The base plate 51 is preferably formed of three layers. The bottom 53 forms a backside layer for the guide track 50, which is oriented towards the embroidery base when the feed device is installed (FIG. 4). An outlet or outlet opening 91 is also formed in this lower portion 53 (FIG. 9). The individual piece 30 can be transferred to the individual piece holder 19 through this outlet opening 91 only. Thus, since the diameter of the outlet opening 91 of the individual piece holder 19 is slightly larger than the individual piece 30 itself, the individual pieces can be accommodated in the individual piece holder 19 with slight movement. This reduces the risk of needle brake, since the individual pieces housed in the individual piece holder 19 are movable. The intermediate intermediate layer 57 (FIG. 4) forms the boundary of the guide track 50, thereby forming the width and depth, and linearly advancing the guide track 50. The recess 40 in the intermediate layer 57 also forms a guide for the punch 35 of the feed mechanism 13. In addition, individual piece holders 19 are formed in the intermediate layer 57. This individual piece holder has a recess for accommodating the individual piece 30. The recess is formed so that the individual pieces can be received at an angle therein. With the vertical alignment of the feed device, the individual pieces are fixed at their peripheral ends and separation is prevented. Preferably, the individual pieces are received in the recesses with slight lateral movement. The individual pieces may pass through the cylindrical recess in the axial direction through the outlet opening 91.

The lid 59 (FIG. 2) covers the guide track 50 to the extent that the individual pieces 30 are not separated from the magazine 15 or the feed path 17. Preferably, the lid 59 has openings and can see the level of filling of the magazine 15. The lid 59, which covers the individual piece holder 19 and at the distal end disposed across the needle, preferably has a U-shaped recess 65, so that during operation, the needle may be separated from the individual piece holder ( It may penetrate the central opening of the individual pieces 30 disposed in 19. The U-shaped recess 65 is preferably smaller than the diameter of the individual piece housed in the individual piece holder, so that the piece does not slip through the recess 65 (FIG. 2).

The feed mechanism 13 has a lever 37 driven by a gear 153, which is disposed at a first end that is rotatably attached to the shaft 157. In addition, the gear 153 is rotatably attached to the shaft 157. The lever 37 is hinged to the sled 39. In the sled 39, the punch 35 is arranged to move up and down by the sled. The bolt 41 is received in a bore hole in the sled 39, where the bolt engages a slot formed in the longitudinal direction of the lever 37, or an elongated hole 43 in the lever 37 (FIG. Mesh with 4). Through this engagement, the sled 39 moves up and down within the guide plate 51 when the lever 37 moves up and down together with the gear 153. The sled 39 is guided in the recess 40 of the lid 39 of the base plate 51 (FIGS. 1 and 2). The punch 35 is disposed on the inner surface of the lid 59 and the sled 39 lies on the outer surface of the lid 59. For installation, the holes may be formed in the base plate 53 in the region of the punch 35. In addition, a coating with reduced friction may be provided.

In a preferred embodiment, the flexible tongue 61 is formed in the lid 59. This flexible tongue 61 lies underneath and presses the individual pieces 30 at the foremost end of the feed path 17, thereby holding them in position. Thus, the fixed individual pieces are pushed to the individual piece holder 19 only when the punch advances.

In FIG. 3, it can be appreciated that the punch 35 is preferably formed narrower than the feed path 17. Thereby, during reloading, the punch 35 can be guided past the highest individual piece in the magazine 15 without pushing the piece again. Due to the reversing punch 35, the individual pieces slide forward in the magazine and consequently lean on each other. During this process, the individual pieces at the top of the magazine 15 extend into the feed path 17. Since the punch 35 is formed narrower than the feed path 17, failure and damage to the punch and the individual pieces 30 can be avoided during reload.

In each case, a pivotable clamping portion 95 (FIG. 3) is arranged on the side of the feed path 17 and the individual piece holder 19. The clamping portion 95 is received in the recess 96 in the intermediate intermediate layer 57 and is pre-tensioned with respect to the feed path 17 by the spring 94. In the process, the front end of the clamping portion 95 extends into the feed path 17 and the individual piece holder 19, so that the individual pieces 30 are fixed in the feed path or the individual piece holder 19.

In conjunction with the punch 35 action, the punch presses the individual pieces 30 placed at the foremost end in the feed path 17 through the two clamping members 95, which will move in the direction of stop 93. Can be. When the individual piece passes through the front end of the two clamping members 95, the clamping members 95 retreat again and stay on the stop surface relative to the individual piece 30 received in the individual piece holder 19. Thereby, the clamping members 95 and the jaws hold the individual pieces 30 in the individual piece holder 19. This makes contact with the interface of the individual pieces parallel to the hole direction of the individual pieces. At the same time, the clamping members 95 abut the feed path 17 and prevent the individual piece 30 from sliding downward. The clamping members 95 are preferably composed of a non-elastic material, but are pretensioned using a spring means, for example a pressure spring 94. The clamping members are preferably installed in the intermediate intermediate layer so that they can pivot in small angles. Alternatively, the clamping members can be formed directly from the spring member.

Using FIGS. 5 to 10, the embroidery process on individual pieces, known to those skilled in the art, will be briefly described, with particular emphasis on the inventive process. In the position according to FIG. 9, embroidery can generally proceed using an embroidery machine, since no individual piece is present in the individual piece holder. Unlike known feed devices, it can be appreciated that the individual piece feed device is arranged in the needle path and in each case the individual pieces are removed parallel to the embroidery surface. Embroidery patterns and positions, where individual pieces, for example rhinestones 30, are embroidered in a manner specified by a program stored in the machine controller. If the needle 97 is in the position according to FIGS. 9 and 10, when a certain position is reached during the preset stitching, the rhinestone is pushed into the individual piece holder 19 using the punch 35. This rhinestone is then sewn by the needle 97, which moves towards the embroidery surface 67, through which sewing is done (FIGS. 5 and 6).

In the case of a Shipley embroidery machine, the needle 97 forms an intermediate stroke, so that a loop is formed in the needle thread, through which a shuttle can slide (FIG. 8). In this process, the needle thread is woven together with the rear thread. The needle 97 is pulled back and the thread is tightened around the rhinestone by sewing (FIG. 10). The individual piece holder 19 is now empty. The punch 35 retracts again, and as soon as the punch 35 opens the feed path 17, the leading rhinestone of the magazine descends into the feed path 17. Since the frontmost rhinestone of the feed path 17 is fixed by the spring means 61 and / or the clamping member 95, the rhinestone reaches the individual piece holder 19 under the influence of gravity. As a result, the punch 35 is in a state capable of pushing the rhinestone forward. The embroidery machine performs the necessary stitching to firmly embroider rhinestones, the embroidery base is held under tension, and the frame moves in the x and y directions. The embroidery machine embroiders the pattern further until the next rhinestone is embroidered.

The peculiarity of this method is that after separation the individual pieces are fixed by the individual piece holders 19 and are independent of the remaining individual pieces and are seated on the needle until they move, without mechanical coupling with the other individual pieces, the individual piece holders Is ejected from and immediately guided in the direction of movement of the needle into the intermediate intermediate space between the head 11 and the embroidery base 67.

The second embodiment shown in FIGS. 13 to 15 differs from the first embodiment in that extended recesses 101, 103 are provided in the base plate 53, where the slider 105 is extended. Can be movably guided in the recesses. Another difference is that the magazine is not present in the base plate but is disposed in the base plate 51. For this purpose, the cylindrical engagement piece 107 is arranged on the guide channel 50. The joining piece 107 has a joining flange 109, with the individual pieces stacked on top of each other, a magazine can be connected to the joining flange 109 (not shown). 13A, 14A and 15A, it should be noted that the engagement piece is not shown for clarity. In FIGS. 13B, 14B and 15B, the joining pieces 107 are shown in longitudinal section to represent the individual pieces 30 received therein. The flexible tube in which the individual pieces are housed can be used as a magazine. Preferably the individual pieces are pretensioned in the direction of the guide channel by a spring, and once the individual pieces are removed, the next individual pieces slide into the feed path.

Another difference of the embodiment according to FIGS. 1 to 4 is that the clamping portion 95 is arranged further rearward, fixing only the individual pieces at the foremost end of the feed path. In contrast, the individual pieces received in the individual piece holders are not fixed by the clamping portion 95. This has the advantage that the individual pieces can be ejected from the individual piece holder without resistance. In FIG. 16, this modified embodiment of the clamping device 95 is shown in more detail.

At the rear end of the feed path 17, a clamping portion 104 is preferably provided in the recess 106 of the intermediate intermediate layer 57 (FIG. 16). This clamping portion 104 also extends into the feed path 17 and is pretensioned with the spring 108. During disassembly of the individual piece feed device, the clamping portion 104 prevents the individual pieces 30 present in the feed path 17 from being separated.

At the rear end, the slider 105 is connected to the sled 39. This allows the slider to move up and down with the tappet 35 using the gear 153 and the shaft 157. The slider 105 is only used when individual pieces are embroidered in a very small area, and these pieces can easily be flipped over and easily separated from the individual piece holder. However, the slider 105 makes it possible to use the feed device according to the invention even in the horizontal position. The front end of the slider 105 is formed of a fork 111. The fork 111 forms a recess 113 between combs (tines) through which the needle can penetrate.

In FIG. 13A, the individual piece feed device is shown at a position where the individual pieces are received in the individual piece holder 19 and the needle 97 is at a distance from the support surface. The slider 105 is in the forward position and closes the outlet of the individual piece holder for the individual piece. In the second position, the needle 97 already penetrates through the central opening 113 of the individual piece 30 located in the individual piece holder (FIGS. 14A and 14B). Here, the slider 105 is still in the forward position. In the third position (FIGS. 15A and 15B), the slider 105 is in the reverse position and the needle 97 removes the individual pieces from the individual piece holder 19. The slider 105 should only open when the needle is in safe contact with the individual piece, preferably only when it touches the fiber.

4 and 17, the coupling for coupling the machine-side drive disclosed in patent EP 1 764 434 will be described in detail below.

To each needle tappet 96, an individual piece feed device is assigned, a switching cam 135 is fixed, and an individual piece feed device is engaged. The individual piece feed device can, for example, be joined and separated in a braid head fashion with the decorative metal plate shown in EP 1 764 434. Thus, the device can be easily changed to known decorative metal plates and braid heads according to the specifications of the pattern to be embroidered, and can be used together in the same machine. However, other coupling devices can also be used.

The coupling 149 includes a coupling wheel 151, which then comes into contact with the spline shaft 3 shown in FIG. 4 and the gear 153 (FIG. 17) of the drive shaft 157. The coupling wheel 151 is installed on the lever 155 and may be pivoted on the drive shaft 157. The spring 156 holds the lever 155 in a position where the coupling wheel 151 abuts against the spline shaft 3 (FIG. 4). Preferably, the coupling wheel 151 is in continuous contact with the gear 153 provided on the drive shaft 157.

The lever 155 has two arms 159 and 161. The coupling wheel 151 is pivotally mounted to the arm 159 and, on the other arm 161, to the gripper and needle tappet of the recovery device for switching the coupling 149 on-off. There is a swinging member 165 that can be driven by.

Although the coupling 149 can be driven directly by the needle tappet, it is preferable to use the switching member 165 to drive the coupling 149. The switching member 165 is designed to firmly hold the lever 155 with the spring 156 force in the engaged position.

As shown in FIG. 17, the switching member 165 includes a drive lever 167, on which a switching arm 168 is disposed. The drive lever 167 can be pivoted in one rotational direction by the needle tappet and in another rotational direction by the recovery device, although not shown in detail, it can be controlled by the machine controller. The drive lever 167 is connected to the cam disk 169 via the shaft 166 and is pressed by the spring 173 against the stopper 171. The cam disk 169 can rotate between two positions that determine the switching on or off position of the coupling 149. The cam track 172 increases from one of these positions to the center between the positions and decreases back to the other position. The cam disk 169 is fixed at these respective positions by the spring 173.

Movement of the cam disk 169 generated by the needle tappet causes movement of the lever 155, and the coupling wheel 151 is engaged with the spline shaft 3 (Fig. 4). If the cam disk 169 is moved in the opposite direction by the recovery device, the coupling wheel 151 is engaged with the spline shaft, but the tooth 175 is engaged with the coupling wheel 151 to prevent this. (FIG. 17). By this, the drive shaft is interrupted via the gear 153. In the individual piece feed device according to the invention, this results in the feed mechanism being fixed at the determined position.
