Definitions

  • CH 660 892 shows a solution for switching the needles and drills, in which needles and drills are driven by one and the same shaft.
  • This solution has the major disadvantage that each time you switch from embroidery to drilling and from drilling to embroidery, all needles or drills have to be disconnected and all drills or needles used have to be connected. This switching through of all needle couplings or drill couplings is repeated twice with each drilling process, even if work continues in the same repeat or in the same combination of embroidery sites. This results in a large number of interconnections of all embroidery points with a corresponding loss of time and energy, especially in the case of drilled goods.
  • CH 651 081 shows a solution in which the needles and drills of all embroidery points are driven by separate shafts. Not only needles and drills, but also other embroidery tools (thread brake, thread monitor, ...) are coupled with a single actuator for each embroidery point. When changing from embroidery to drilling and vice versa, only the corresponding drive shaft is driven or stopped. A coupling or uncoupling of the tools of different embroidery sites only takes place when changing the combination of active and inactive embroidery sites.
  • This solution requires a powerful actuator with appropriate power consumption, or a power amplifier. Since the tools of an embroidery site must be arranged separately, the solution with only one actuator (per embroidery site) requires corresponding mechanical connecting elements for coupling / decoupling the various tools or restrictions in the arrangement of the tools.
  • the aim of the invention is to maintain the advantage of the low number of switching operations by separate drives of the different tools (needle, drill), but to eliminate the complex mechanical switching transmissions and to gain complete freedom in the arrangement of the tools.
  • This is achieved by using several actuators (magnets, pneumatic cylinders, hydraulic cylinders) for each embroidery location, all of which are brought into one or the other end position at the same time with only one switching element per embroidery location.
  • These individual actuators can each be arranged directly on the tool to be switched, which on the one hand gives complete freedom in the arrangement of the tools and on the other hand allows the use of actuators with low power.
  • the connections from the common switching element to the individual actuators (cables, hoses, ...) can be easily implemented without any effort.
  • Actuators are used that have two fixed end positions, in which they can be held optionally. This means that there is a clear status (engaged or disengaged) for all tools in an embroidery site.
  • FIG. 1 schematically shows an embroidery site with such an embroidery site circuit.
  • the needle (2) or drill (3) are held in the needle carrier (4) or drill carrier (5) and guided axially.
  • the needle pawl (6) or the drill pawl (7) they can be coupled or uncoupled to the needle drive tube (15) or drill drive tube (16).
  • Fig. 1.1 shows the pawls in the coupled
  • Fig. 1.2 in the uncoupled state.
  • the drive tubes (15, 16) are firmly connected to the corresponding drive shaft (13, 14) by means of supports (17, 18). In the coupled state, the oscillating movement of the drive shaft (13, 14) is converted into a linear movement of the corresponding tool (2, 3).
  • the embroidery thread (1) is fed to the needle (2) via a thread brake roller (22) and the thread guide (20).
  • the thread brake roller (22) is coupled to the thread brake shaft (21) passing through all the embroidery points via pinion (26) and gear (25).
  • the thread brake shaft (21) can be braked or driven centrally so as to regulate the thread tension and thread delivery.
  • the thread brake roller (22) is mounted on the one-armed thread brake lever (23). In Fig. 1.1 the thread brake roller (22) is coupled to the thread brake shaft (21).
  • the actuator (24) the thread brake lever (26) is raised and the pinion (26) and gear (25) are disengaged, whereby the thread brake roller (22) is decoupled from the thread brake shaft (21).
  • further actuators of an embroidery location can be activated or deactivated, or coupled or uncoupled to their respective drives, by further actuators.
  • One switching element (12) is provided for each embroidery point, which is connected to the actuators (8, 9, 24) by means of appropriate connections (19) (electrical cables, compressed air or hydraulic hoses, ). With a switching of the switching element (12) all actuators (8, 9, 24) of this embroidery point are actuated simultaneously and in the same direction, ie the embroidery point is switched on or off as a whole.
  • the connections (19) can be arranged very flexibly, so that no consideration of the common switching has to be taken into account when arranging the tools in an embroidery location.
  • Line A represents the beginning of the linearly arranged embroidery points numbered from 1. Depending on the machine length, the number is approximately 100 to 700 embroidery points.
  • Line B shows a specific repeat circuit, in this case a three repeat (in embroidery terms a 12/4 repeat), whereby only the first of three needles is embroidered. If you now switch from needle combination A to needle combination B, all the previous embroidery positions had to be reset to a basic position (ON or OFF). Only then could the new combination (eg B) be switched. With the new solution with actuators with fixed end positions, it is first determined in a simple program by comparing combination B and combination C which embroidery points can remain in their switching state (eg embroidery points No. 1, 2, 6, 7, 8, 12 .. .), or which must be switched on (No. 3, 5, 9, 11) or switched off (4, 10). This procedure results in a much shorter changeover time to a different combination of embroidery positions. At the same time, the number of switching operations and thus the necessary switching energy is significantly reduced.
  • switching element is understood to mean a pure switching element without force, such as, for example, actuating elements which serve to switch and control a material or energy flow, such as, for example, hydraulic or pneumatic reusable valves, electrical switches and the like.
