Definitions

  • the present invention relates to a multi-head embroidery machine according to the preamble of claim 1 and a tenter according to the preamble of claim 14.
  • a first type of classification is based on the number of thread systems involved in the embroidery process: in some machines, the embroidery is produced by only one thread system, other machines require two thread systems, namely, in addition a second sub, Hind, spool, shuttle or bobbin thread.
  • a second type of classification is based on the number of needles working at the same time:
  • the one-needle embroidery machines include the Singer, Eagle and Crank embroidery machines.
  • Multi-needle or rapport embroidery machines are shuttle embroidery machines and the hand embroidery machine.
  • the multi-head embroidery machine which can be assigned to neither of the above two groups.
  • the principle of this machine is based on a large table top 3, 4, 6, 10 or 12 Singer embroidery machine heads are mounted, which are set by a common drive shaft in motion. The synchronization of the heads thus achieved is necessary so that all needles simultaneously pierce or are out of the embroidery ground.
  • the embroidery bottom can be clamped individually for each head in an embroidery hoop.
  • These hoops are fastened by means of screw connections to a gate-like structure, which is controlled by a small automaton in the horizontal plane.
  • the embroidery field is approx. 240 x 200 mm.
  • the stitch formation organs and the stitch formation process are identical to those of the Singer embroidery machine. The only difference to these is that on each needle still a presser is provided which holds the embroidery bottom during stitch formation. The presser foot is raised whenever the hoop moves.
  • individual embroidery heads are usually equipped with a thread monitor system, which automatically shuts off the machine when the thread breaks.
  • the first multi-head embroidery machines were offered 100 years ago by the German Singer sewing machine factory (see “ The Art Of Embroidery, Coleman, Schneider, 1991 ).
  • the first automatic multi-head embroidery machine was launched on the market in 1927 (also known as the "Würker Automat”). Technology and Product Theory, Klaus Freier, VEB book publisher, für, 1991, pages 130 to 131 ).
  • each needle point comprises a thread monitor (optional), a thread guide (also referred to in the literature as thread take-up lever), thread guide devices, including stitch-compensating thread tension parts, for the upper thread and a needle arranged on a needle plunger which moved up and down and from a drive unit is driven.
  • the aforementioned stitch-forming components are also referred to in the present description as an upper thread unit.
  • the embroidery heads of the multi-head embroidery machines are mounted laterally displaceable on a support arm.
  • each stick head below each stick head is a throat plate in which a needle hole is provided for the needle and which locally defines the point of embroidery.
  • Each needle of an embroidery head is displaceable laterally to the mentioned embroidery point, on which the embroidered embroidery material spanned in a clamping frame which can be displaced in the x- and y-direction during operation rests.
  • the needle which is located at the embroidery site, penetrates through the embroidery material and into the needle hole during the movement of the needle.
  • the upper thread is passed through the embroidery material and formed by a corresponding needle movement, a loop on the back of the embroidery material. Through this loop then the lower thread is guided.
  • the upper thread is tightened and formed in the embroidery a so-called stitch.
  • embroidering only one of the needle points is active, namely the one which is located at the embroidery point.
  • the embroidery heads of the mentioned multi-head embroidery machines are arranged in a known manner in a specific Rapportlie along the support arm.
  • a characteristic of these multi-head multi-needle embroidery sewing machines is therefore that there are a plurality of needle locations per embroidery head. This has the advantage that each needle point can be equipped with a different thread and therefore colored embroidery can be performed by always only the corresponding needle is put into action.
  • the needle tappet and their assigned thread levers of a group of needles are usually stored in a carrier, which brings the selected needle tappet and the associated thread lever before a stationary mounted drive for the purpose of changing the thread by moving.
  • a conventional multi-head multi-needle embroidery sewing machine is exemplary in the FIGS. 1 and 2 shown.
  • This comprises a frame 201, an embroidery table 203 arranged on the frame 201 and a plurality of embroidery heads 205 arranged in series above the embroidery table FIG. 2 it can be seen, each embroidery head 205 has a plurality of needle points equipped with a needle 215 each.
  • Each needle point includes stationary thread guide elements 207 or thread brakes, an up and down movable thread receiving lever resp. Thread guide 209, Fadenumlenkmaschine 211 and one on a needle cancer 213 with needle tappet 214 arranged needle 215.
  • each needle plunger 214 is equipped with a presser 217.
  • the embroidery frames 219 can be inserted into a large clamping frame 221 which extends across the width of the embroidery table 203.
  • the clamping frame 221 is displaceable in a known manner in the x and y directions.
  • the embroidery heads are arranged on a linear guide 223 and displaceable along it in the x-direction.
  • the tenter of the conventional multi-head multi-needle embroidery sewing machines comprises two spaced-apart fabric holding elements, between which the fabric is fastened.
  • the material which is also referred to in the jargon as the embroidery ground, this must be stretched and clamped sections.
  • the embroidery is also stretched and clamped.
  • the entire clamping frame is movable by means of known guide devices and drive means in the x and y directions in order to be able to embroider the entire surface of the embroidery material.
  • the bobbin thread for the embroidery head is provided by a bobbin respectively, which is accommodated in a housing as used in any conventional sewing machine.
  • On the spool can be wound up to 100 m thread. This has the consequence that in the multi-head embroidery machines, the spools are changed relatively of. If the thread supply is used up, the spool must be changed.
  • a disadvantage of the known multi-head multi-needle embroidery sewing machines is that they have a relatively large space requirement, which corresponds in one direction to twice the depth (y-direction) of the clamping frame.
  • the large clamping frame also brings the disadvantage that during operation of the machine, the spool with the lower thread is poorly accessible. It is often necessary to crawl under the tenter to replace the spool to advance to the spool, or it may need to be climbed on the machine to fix upper thread breaks.
  • the large clamping frame thus leads to a significant disability in the operation of the embroidery machine.
  • the publication DE-A-37 20 907 discloses a shuttle embroidery machine in which two panels are arranged one above the other.
  • a convertible belt tensioning lever which is arranged at the free end of the drive shaft, either the upper or lower belt can be moved and thus a forward or return transport of the fabric can be accomplished. From the DE-A-37 20 907 does not show how the fabric could be stretched or curled in a stretched state.
  • the EP-A-0 148 127 discloses a gate for a large embroidery machine, in which the fabric waves are connected to each other via a traction means, in such a way that the pulp waves remain rotatable only in the untensioned state.
  • a drive for tensioning the wound on the fabric waves Stickereig serves a relative to the gate freely displaceable motor.
  • the pulp shafts have frontally each have a toothing in the form of a ring gear in which a pivotally mounted pawl can engage. With loose material the rear end of the pawl comes into abutment with a plate, whereby the pawl disengages from the teeth and the shafts are freely rotatable.
  • a disadvantage of this gate is that under tension not nachgewellt, ie material can be transferred from one to the other shaft, since the interposed motor limits the displacement.
  • Object of the present invention is to propose a multi-head embroidery machine, which does not have the disadvantages mentioned above.
  • it is an object to provide a multi-head embroidery machine which is more efficient than conventional machines.
  • Another aim is to provide a machine in which larger embroidery grounds can be embroidered than with conventional multi-head embroidery sewing machines with a smaller footprint.
  • Yet another goal is to provide a machine that has a small footprint.
  • the present invention relates to a multi-head embroidery machine.
  • This has at least one embroidery head, which has a plurality of needle locations.

  • Each needle point comprises organs, such as thread guides, thread guiding devices, and a needle plunger, to each of which a needle can be fastened.
  • the needle plungers can be moved back and forth in the z-direction.
  • the aforementioned organs are collectively referred to as upper thread unit.
  • Each embroidery head is assigned a lower thread unit. Between the upper thread unit and the lower thread unit, a clamping frame for clamping an embroidery material is arranged.
  • the clamping frame has two in the y-direction spaced from each other first and second fabric holding elements.
  • multi-head embroidery machines have a transmission, e.g. with a central drive shaft to synchronously drive the upper and lower thread unit.

  • the embroidery machine according to the invention has the great advantage over the conventional multi-head multi-needle embroidery sewing machines that it requires much less space than the conventional ones. Thanks to the fabric shafts, the depth of the tenter can be reduced to about half the original dimensions. Nevertheless, larger fabrics can be embroidered, because a large fabric surface can be undulated on the fabric waves Another advantage is that the machine is more accessible, eg for a thread change, and that the embroidery ground can be easily waved, since the fabric always remains clamped.

  • the coupling with each other on a form-fitting cooperating coupling parts is a simple, inexpensive and robust design.
  • the coupling is designed as a slip clutch. It is particularly advantageous if the clutch can slip in the torque transmission in a particular direction of rotation, but not in the torque transmission in the opposite direction of rotation.
