Definitions

  • the invention relates to a coupling device for textile machines according to the preamble of claim 1 and a dobby with such a device.
  • Known devices of this type have an eccentric disc which is slidably or rotatably arranged on a main shaft, a connecting rod which on the
  • Eccentric disc is mounted, a pawl which is pivotally arranged on the eccentric disc and a device for actuating the pawl, which comprises a plurality of mechanical elements. Furthermore, a locking device is provided to secure the pawl in the engaged state. Several mechanical elements are also required for this.
  • the invention has for its object to provide a coupling device for textile machines, which does not have the disadvantages mentioned.
  • the device and the pawl are arranged in close proximity to one another on the eccentric disc and are directly connected to one another. As a result, the pawl is positively brought into the respective position and held by the device, causing a malfunction of the
  • Coupling device prevented and the switching phase of the coupling device is shortened. With the shorter switching phase, shorter standstill times of the dobby can be realized, which results in a higher working speed.

  • the coupling device in question here is a coupling device for a rotary dobby, which moves the heald frames up and down via a lever system and which has a main shaft 1 on which the device is slidably or rotatably arranged.
  • the main shaft 1 has two grooves 2, 2 ′ which are formed diametrically opposite on the circumference of the main shaft 1.
  • the device contains at least one eccentric disk 3, which is mounted on the main shaft 1.
  • a pawl 4 and a device 6 for actuating the pawl are arranged on the eccentric disc 3 and are directly connected to one another.
  • the device contains a connecting rod 5, which is arranged rotatably on the one hand on the eccentric disc 3 and on the other hand is connected to the lever system 7.
  • the main shaft 1 rotates intermittently and comes to a standstill after each rotation by 180 °.
  • FIG. 1 shows the main shaft in the standstill phase, in which the pawl 4 is held outside the coupling groove 2 by means of the device 6, so that when the main shaft 1 is turned further, the coupling device cannot move. If the device 6 is now actuated in accordance with the pattern in a standstill phase, the pawl 4 is inserted into the coupling groove 2. In the following cycle, the main shaft 1 rotates 180 °, whereby the eccentric disc 3 with the latched pawl 4 follows this rotation and thereby the connecting rod 5 leads to the other end position and thereby moves the shaft 9 via the lever system 8.
  • Figure 2 shows the coupling device according to a
  • Lever system 7 brings the shaft 8 into its low lying position. If the device 6 is now operated according to the pattern in the standstill phase, the pawl 4 is pulled out of the coupling groove 2, 2 * and remains outside the effective range of the coupling groove 2, 2 ', so that the coupling device remains in this rest position.
  • FIG. 3 shows a coupling device in the standstill phase of the main shaft 1.
  • the pawl 4 is engaged in the coupling groove 2, 2 and is locked by the device 6.
  • Figure 4 shows a coupling device in a phase of movement of the main shaft 1.

  • Coupling device is set into an eccentric movement.
  • Figure 5 shows a coupling device after a half rotation of the main shaft 1 with pawl 4 by 180 °.
  • the pawl 4 is connected to the device 6 and is thereby locked.
  • the figure shows the pawl 4 drawn from the coupling groove 2, 2 '.
  • the device has a device 6 for actuating the pawl 4.
  • the device 6 can have various embodiments.
  • an electrical control is provided, the device 6 being either an electromagnet or a linear motor which is controlled by the machine control 22.
  • the armature part of the electromagnet or of the linear motor is connected to the pawl 4
  • control takes place pneumatically or hydraulically.
  • a working cylinder 26 is provided for this purpose.
  • the device 6 is a piezoelectric element 28, the free end of which is connected to the pawl 4.
  • the device contains at least one eccentric disc 3 on which a pawl 4 for coupling the eccentric disc to a main shaft 1 and a device 6 which is directly connected to the pawl 4 and a connecting rod 5 which is mounted on the eccentric disc.
  • the pawl 4 is actuated positively by the device 6 and brought into and out of engagement with the main shaft.
