Definitions

  • the present invention relates to an embroidery machine with a main shaft, on which there is at least one eccentric for actuating one of the thread guides.
  • the eccentrics for actuating the thread guides were fastened to the main shaft with the aid of screws.
  • the eccentric for example, had a hub made of two shells that surrounded the main shaft. After the position of the eccentric required for the embroidery machine to work was determined, the screws on the hub were tightened and the position of the eccentric was fixed on the main shaft.
  • the embroidery machine first had to be stopped, the aforementioned screws loosened, the eccentric adjusted for trial purposes, the screws retightened, the machine started up and the position checked of the eccentric is correct. If not, then the machine had to be stopped, screws loosened, etc. This procedure was not only time-consuming, it also did not make it possible to optimally adjust the position of the respective eccentric. The consequences of an insufficient adjustment of the eccentrics on an embroidery machine are from the Practice well known.
  • the object of the present invention is to eliminate these and still further disadvantages of the known embroidery machine.
  • the present embroidery machine can be, for example, a shuttle embroidery machine of a known type. Therefore, only that section of such an embroidery machine in which the invention is implemented is shown here.
  • the embroidery machine has a stand 1 on which the individual parts of the machine are attached. In the stand 1 bearings 2 for the main shaft 3 of the embroidery machine are attached. The main shaft 3 is connected to a known drive device, which is therefore not shown here.
  • the eccentric 5 for the large thread guide (not shown) and the eccentric 6 for the small thread guide (likewise not are located on the main shaft 3 shown).
  • These eccentrics 5 and 6 are assigned eccentric rollers (not shown) which are mounted in push rods and which convey the movement of the thread guides required for the function of the embroidery machine.
  • the eccentrics 5 and 6 are firmly connected to each other so that the temporal cooperation between the two thread guides is ensured.
  • the first spacer 9 contains two shell-shaped halves 13 and 14 which surround the main shaft 3. Screws (not shown) pass through these shells 13 and 14 perpendicular to the shaft axis, with the aid of which shaft 3 can be clamped between the two shells 13 and 14.
  • the eccentrics 5 and 6 which serve to drive the thread conductors, are loosely seated on the main shaft 3. This means that these eccentrics 5 and 6 would rotate freely on the main shaft 3 if no measures were taken against them.
  • the eccentrics 5 and 6 are connected to a wheel 15 with the interposition of a disc 16. This second wheel 15 and the intermediate disc 16 are also loosely seated on the main shaft 3.
  • the connection mentioned is made with the aid of screws 17 which extend through the parts 5, 6, 15 and 16 of such a group.
  • This group 5, 6 and 15 to 17 thus sits loosely on the main shaft 3 as a whole. However, this group must not move along the main shaft 3 if the function of this machine required to solve the given task is to be achieved. This is achieved, for example, with the aid of adjusting rings 31 and 32 which are attached to the main shaft 3 on both sides of this group.
  • An intermediate piece 20 is provided, which brings about the connection between the main shaft 3 and the group 5, 6 and 15 to 17 which is loosely seated thereon.
  • this intermediate piece 20 is designed as a pinion which meshes with the wheels 10 and 15. Since these wheels 10 and 15 have the same diameter in the example shown sen, the pinion 20 is cylindrical.
  • the peripheral portion of the pinion 20 is provided with bevel teeth which divide the surface of the pinion 20 into two halves 21 and 22. In the first pinion half 21 shown on the left, the sections 23 of the angular teeth run downwards, while the tooth sections 24 in the second pinion half 22, shown on the right, are ascending.
  • the peripheral portions of the wheels 10 and 15 are also provided with teeth 25 and 26, the shape and course of which are such that the respective wheel 10 or 15 can be in engagement with one of the halves 21 or 22 of the pinion 20. For this purpose, the teeth 25 on the first gear 10 ascend and the teeth 26 on the second gear 15 descend.
  • the first gear 10 is coupled to the main shaft 3 so that it rotates with the shaft 3 when the machine is in operation.
  • the fixed pinion 20, ie not rotatable about the Haput shaft 3, is driven by this first wheel 10.
  • the second wheel 15 is in engagement with the second half 22 of the pinion 20, which is otherwise freely rotatably mounted on the main shaft 3 but rotates around the main shaft 3 at the same speed as the first wheel 10 because of the coupling via the pinion 20 the pinion 20 at a certain position in the direction of the main shaft 3 retains, the angular position of the two wheels 10 and 15 relative to the main shaft 3 is the same.
  • the angular position of the eccentrics 5 and 6 can also be adjusted while the embroidery machine is in operation if the pinion 20 is mounted in such a way that it can be moved during the operation of the machine.
  • the present machine is provided with a device 35 for displacing the pinion 20 in the longitudinal direction of the main shaft 3.
  • This device 35 has a fork-shaped guide 36 for the pinion 20, the tines of which lie at the two ends of the pinion 20.
  • the pinion 20 itself is rotatable on an auxiliary shaft 37 and is slidably mounted along it. This shaft 37 is fastened in the stand 1 and it runs practically parallel to the main shaft 3.
  • the main body of the guide 36 is provided with a threaded sleeve 38, which is seated on a threaded spindle 39.
  • This spindle 39 is in the frame 1 the machine is rotatably mounted and it can either be rotated by hand, for example by means of a crank, or with the aid of a drive device (not shown). The operation of this drive device can also be preprogrammed by the punch cards used to control the embroidery machine.
