Definitions
- the invention relates to a coupling device for textile machines according to the preamble of claim 1.
- Coupling devices of this type are known.
- This coupling device contains coupling elements which are brought into and out of engagement by means of spring force.
- the coupling process takes place during the switching phase of the dobby.
- the switching times provided for the coupling process are very short in the case of snow-bearing dobby machines. So very strong springs have to be used.
- the coupling element is engaged or disengaged, the strong spring force must be overcome.
- the object of the invention is to provide a coupling device which does not have the disadvantage mentioned above and which works reliably with few and simple elements at a high working speed.
- the object is achieved by the features listed in claim 1.
- the pawl is actively brought into and out of engagement with the main shaft by means of the device depending on the pattern data.
- the positive actuation of the pawl advantageously improves the engagement and disengagement, so that the device can be used in snowing dobby machines.
- the coupling device is simple and therefore inexpensive to manufacture and use energy.
- FIG. 1 shows a side view of an embodiment of a coupling device according to the invention
- Fig. 6 shows a first embodiment of a
- FIG. 7 shows a second embodiment of a device for actuating the slide
- Fig. 8 shows a third embodiment of a
- Fig. 9 is a side view of another embodiment of an inventive
- the coupling device in question 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 an eccentric disk 3 which is mounted on the main shaft 1.
- a pawl 4 two slides 5, 5 ', two guide members 21 and a toggle 6 are arranged.
- the slides 5, 5 ' are arranged diametrically opposite one another and are guided in the guide members 21 so as to be radially displaceable.
- the one slider 5 is articulated to the pawl 4 and the other slider 5 'to the toggle 6.
- the slider 5 ' are each provided with a coupling portion 11, 11 ⁇ .
- the device contains a connecting rod 7, which on the one hand is rotatably arranged on the eccentric disc 3 and on the other hand is connected to the lever system 8 and a device 10 for actuating a slide 5 or 5 1 , which is mounted on the connecting rod 7 via a carrier 19.
- the device has a locking device 12 known per se for the pawl 4. The operation of the device is described below.
- 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, which is connected to the device 10 via the slide 5, is held outside the coupling groove 2, so that when the main shaft 1 continues to rotate, the coupling device cannot move. If the device 10 is now operated 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 by 180 °, the eccentric disc 3 with the latched pawl 4 doing this rotation and thereby the connecting rod 7 leading into the other end position and thereby the shaft via the lever system 8
- Figure 2 shows the coupling device after a half rotation of the main shaft 1 with the pawl 4 by 180 °.
- FIG. 10 shows a coupling device in the standstill phase of the main shaft 1.
- the pawl 4 is engaged in the coupling groove 2, 2 '.
- the pawl 4 is locked by the device 10 via the interposed slide 5.
- Figure 4 shows a coupling device in a phase of movement of the main shaft 1.
- the pawl 4 is engaged in the coupling groove 2, 2 • and
- Coupling device is set into an eccentric movement.
- the locking device 12 locks the
- Figure 5 shows a coupling device after a half rotation of the main shaft 1 with pawl 4 by 180 °.
- the slider 5 ' which is connected to the pawl 4 via a lever 6, is connected to the device 10 and the pawl 4 is thereby locked.
- the figure shows the pawl 4 drawn from the coupling groove 2, 2 '.
- the pawl 4 is actuated via the slide 5', which is connected to the pawl 4 via a lever 6.
- the device has a device 10 for actuating the pawl 4.
- the pawl 4 is articulated to the slide 5, which is guided in the guide member 21 ( Figure 6).
- the device 10 can have various embodiments.
- an electrical control is provided, the device 10 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 has at the free end a section 24, which can be brought into and out of engagement with the coupling section 11, 11 'of the slide 5, 5'.
- control takes place pneumatically or hydraulically.
- a double-acting working cylinder 26 is provided, the piston rod of which has at the free end of section 24.
- the device 10 is a piezoelectric element 28, the free end of the section 24.
- the device contains two pawls 4, 4 ', which are arranged in mirror image on the eccentric disc 3 and with the opposite grooves 2, 2' in and out
- Intervention can be brought.
- the mode of operation corresponds to the device according to FIG. 1.
- the device contains an eccentric disc 3 on which at least one pawl 4 is arranged to couple the eccentric disc to a main shaft 1 and a slide 5, 5 * is arranged, which is articulated to the pawl 4 and a connecting rod 7 which is on the eccentric disc is stored and is provided with a device for the slide 5, 5 '.
- the pawl 4 is actively operated via slide 5, 5 'and brought into and out of engagement with the main shaft.
