Definitions

  • the invention relates to a multi-needle sewing machine with at least one needle bar and fastening devices for the individual needles and with at least one hook shaft, on which hook hook holders are fastened with the hook hooks.
  • Multi-needle sewing machines for sewing large-scale material are equipped with a large number of needles up to 120 needles or even up to 140 needles per needle bar. If a plurality of needle bars, in particular two or three needle bars common to the row of needles, are provided, the number of needles increases accordingly.
  • the individual needles include hooks which, together with the needles, represent the essential parts of the sewing organs.
  • the gripper hooks are attached to common back and forth oscillating gripper shafts via gripper hook holders.
  • the invention has for its object to provide a multi-needle sewing machine that allows a quick and easy changeover to another sewing pattern.
  • the object is achieved in that manually operable quick-locking devices are provided between each needle or a needle holder for each needle and the needle bar and / or between the hook hook holder of each hook hook or each hook hook and the hook shaft.
  • the main advantage is that the quick locking devices for the previously mentioned sewing organs can be released quickly and easily by hand and can be locked again by hand after the sewing organs have been moved to another location.
  • FIG. 1 illustrates, for the sake of clarity, the most important parts of a multi-needle sewing machine, which in a known manner has an upper crosshead 1, an upper machine frame part 2 and a driven needle bar holder 3.
  • the needle bar holder 3 carries three needle bars 4, 5, 6 which run parallel to one another and to which rows of needles are fastened perpendicular to the image plane in FIG. Accordingly, only the front individual needles 7, 8 and 9 are visible in FIG. 1.
  • the needles work together with upper threads, of which, for the sake of simplicity, only the upper thread 10 is shown for the needle 7.
  • the reference numeral 11 designates the presser foot
  • the reference numeral 12 shows a part of the sewing material support plate or the needle hole plate through which the needles can reach in upward and downward movement, as well as by the sewing material, which is not shown for the sake of simplicity.
  • the needles work together with gripper hooks 16, 17, 18, which are attached to the needles on gripper shafts 13, 14 and 15 in rows perpendicular to the image plane of FIG. 1.
  • the gripper shafts are on a lower one Machine frame 19 mounted, which is built on a lower crosshead 20.
  • a lower thread 21 is guided in each looper hook, only the lower thread for the looper hook 16 being indicated in FIG. 1 for the sake of simplicity.
  • the quick-locking device has for each needle a longitudinal guide 27 for the needle holder 28 provided on the needle bar 4 and an actuating bolt 32 which can be pivoted transversely to the longitudinal guide on the needle holder 28 and finally a locking point 31 for the actuating bolt 32.
  • the needle holder 28 In the inclined swivel position of the actuating bolt 32 shown in the middle of FIG. 5, the needle holder 28 can be inserted into the longitudinal guide 27 from below.
  • the actuating bolt 32 is locked together with the needle holder 28 in the longitudinal direction, that is to say in the direction perpendicular to the image plane of FIG. 5.
  • the longitudinal guide 27 is advantageously formed from a notch in the needle bar 4, which is approximately triangular in cross section, and from a locking plate 29 covering the notch, the locking plate 29 advantageously being screwed to the needle bar 4 via a spacer 30.
  • the needle holder 28 is held on three longitudinally extending, ie perpendicular to the image plane of Figure 5 and distributed circumferential lines, so that the needle holder 28 is tight and there is no movement.
  • the locking plate 29 has a laterally open semicircular recess 31, which forms the actual locking point.
  • a slot 34 connects to the recess 31, whereby a somewhat resilient web 35 is formed so that the actuating bolt 32 is held in the recess and in the locking position adjacent to the web 35, specifically in the position shown on the left in FIG. 5.
  • a stop piece 33 is attached at a distance below the actuating bolt 32 and laterally projecting, which is located in the locking position just below the web 35.
  • the stop piece 33 advantageously has a thread guide eyelet 41 for the upper thread 10.
  • At least one storage rail 22 for the needles 23 which are not in operation is arranged together with the needle holder and the respective upper thread 10 in the upper region of the machine frame. If a plurality of needle bars are provided, it is expedient to also provide a plurality of storage rails accordingly, with a distance above one another in order to obtain a better overview.
  • the main advantage of these storage rails is that the upper thread can remain in the needle eyelet when the needle holder is deposited on the storage rail after the needle holder has been quickly released and is thus immediately available for later use in the operating position.
  • the storage rail 22 is provided with suitable clamps, snap-in or insert holders 24.
  • a quick locking device is also provided between the gripper hook holder 36 and the gripper shaft 13.
  • An embodiment is shown in Figure 7.
  • the quick locking device has a locking bracket 38 which is articulated on the gripper hook holder 36 by means of a pivot pin 37 and which engages around part of the gripper shaft 13.
  • the outer region of the locking bracket 38 is expediently designed to be resilient, so that it resiliently abuts the rounded surface 40 of the gripper shaft 13.
  • the end of the locking bracket 38 is provided with a handle 39.
  • the quick locking device is provided between the gripper hook holder 36 and the gripper shaft 13.
  • a manually operated plug-in locking device for example in the manner of a bayonet lock, can also be provided between the gripper hook 16 and the gripper hook holder 36.
  • At least one storage rail 25 for the gripper hooks 26 and 16, which are not in operation, is arranged in the lower region of the machine frame.
  • the looper hook or the looper hook holder, together with the respective lower thread 21, can also be put down on this storage rail, so that a cutting of the lower thread before the dismantling of the looper hook or looper hook holder is not necessary and the lower thread is immediately available for reassembly Available.
