Definitions

  • the invention relates to an embroidery machine with a directly or indirectly the movement of the electrically or hydraulically actuable drive elements, at least for the punch card triggering the embroidery gate.
  • a device for quilting or embroidering fabric webs or the like is already known, in which the otherwise customary embroidery hoop is formed from two carriages, one carriage being displaceable in the horizontal and the other in the vertical direction, so that the resulting movements make the necessary movements for the embroidery process.
  • the control is carried out by a programmer, which is provided with a jacquard tape, which is perforated according to a certain key in several rows according to the desired pattern, the tape passing a number of buttons, each time triggering a hole in the tape pulses .
  • a direct reading of the punched card strip is therefore provided, which can result in significant malfunctions, for example as a result of damaged punched cards or through punched-over punched cards.
  • a drive for adjusting embroidery frames on embroidery machines has also become known, in which the adjustment movement of the embroidery frame is generated both in the horizontal and in the vertical direction by known hydraulic actuators which are connected to actual value transmitters and via electrohydraulic control valves by a setpoint transmitter controlled by punch cards are controllable.
  • a control device is provided here, which represents a large reduction in the size of the known mechanical automatic control system for embroidery machines, the movements for the direction of rotation and the size of the two drive directions being generated in the conventional manner in a greatly reduced mechanical system and for the electrical one Setpoint generator is transmitted.
  • Such an arrangement can of course only be used with new embroidery machines, since all parts of an already existing control machine can no longer be required.
  • such a mechanism is very expensive, which must mechanically adjust the setpoint adjuster.
  • the invention has set itself the task of avoiding these disadvantages and to provide a punch card control for an embroidery machine, which is simple in its construction and yet functional.
  • the punch card controller from a corresponding number of the holes of the punch card scanning, known per se and directly responding to the movement and / or standstill of the boards, electrical and / or electronic switching elements, for example one with the number The number of channels equipped with electrical and / or electronic readout devices, corresponding to the circuit boards, as well as a control device known per se that interconnects the setpoint adjustment, from which the control impulses lead to the drive elements.
  • a simple conversion of existing embroidery machines can also be carried out, since only electrical and / or electronic switching corresponding to the already existing boards for scanning the punch card elements must be assigned. Furthermore, drive elements for the gate movement are then to be provided. It has been shown that a design according to the invention can eliminate a large part of the mechanical parts otherwise required, namely approximately 350 such parts, which makes up approximately 50 to 60% of the mechanical parts provided in a conventional embroidery machine. This not only enables the possibility of a higher speed and thus a faster sequence, but also results in a significant reduction in noise. This noise reduction results both in the case of new embroidery machines equipped in this way and in the case of old embroidery machines converted in the manner according to the invention. In addition, wear, repairs, lubrication and maintenance costs are significantly reduced and the service life is increased considerably.
  • FIG. 1 shows a schematic arrangement of a scanning roller with a scanning board in a side view
  • Fig. 2 is a plan view of this arrangement.
  • the punch card control is shown schematically.
  • the endlo Sen tape existing punch card 2 drawn, on this scanning roller mandrels 3 are provided which engage for the exact transport of the punch card 2 in corresponding transport holes 4.
  • slidable boards 6 are provided in their longitudinal direction. These boards are held in their front rest position by a spring 7, in which they are supported on a stop 8.
  • the scanning roller 1 When the embroidery machine is operating, the scanning roller 1 is rotated step by step in the direction of the arrow 9, with an approximately horizontal movement of the scanning roller in the direction of the arrow 10 taking place after each step. This movement causes the boards 6 to be pushed back in the direction of the arrow 11, with the exception of those boards to which a hole 5 of the punch card 2 is assigned in this position. These boards 6 remain in their rest position due to the action of the spring 7. Then the scanning roller 1 is again returned to the front rest position against the direction of the arrow 10, so that the boards 6 pushed backwards also reach their front rest position as a result of the spring 7. These movements take place at continual intervals in accordance with the advance of the punch card 2.
  • the thread roller can be assigned a drive element that can be actuated by the punch card controller. Since the size of the adjustment of the embroidery hoop is given in the control device 13, a corresponding thread advance can also take place during the movement of the embroidery hoop or shortly before the movement of the embroidery hoop, so that there is a substantial reduction in the number of thread breaks.
  • impulses can be superimposed, which cause the thread roller to run forwards and backwards.
