Definitions

  • the present invention relates to a gripper device on a ring spinning or ring twisting machine for grasping empty and / or spooled tubes by means of pins attached to a carrier extending along the machine, which pins can be immersed in the cylindrical interior spaces of the tubes by a predetermined movement of the carrier.
  • a pin is provided for each sleeve and the pins are tapered at their front ends when immersed and the detected sleeves are held by pressing one sleeve against the other and the pin immersed in the interior thereof.
  • cores or bobbins are automatically detected in various operations in order to be moved from one location to another location.
  • a large number of such sleeves or bobbins often have to be detected simultaneously, particularly in ring spinning or ring twisting machines.
  • gripping members attached to a carrier are inserted into the cylindrical interior spaces of the sleeves or coils and the sleeves are gripped by pressing these gripping members together and the inner sleeve wall.
  • This is characterized in that a cylindrical extension made of elastically flexible material is provided on each pin, which extends away from the front, conically tapered pin end.
  • the front end of the extension abuts against this sleeve edge in the embodiment according to the invention.
  • the extension and then the pin slide along the edge of the sleeve; whereby the sleeve is pushed sideways and damage is avoided.
  • the pin either plunges into the sleeve or bumps past it outside of the sleeve.
  • a large number of spindles are usually lined up along their length on ring spinning and ring twisting machines.
  • a conveyor belt and a carrier with gripping members extend the length of the machine.
  • the carrier serves to move sleeves from the conveyor belt to the spindles or coils (spooled sleeves) from the spindles to the conveyor belt.
  • FIG. 1 shows such a carrier 11.
  • a pin 13 is fastened to it by means of a screw 12. This consists of a hard material, e.g. Metal.
  • a screw 12 In the longitudinal direction of the beam 11, i.e. perpendicular to the plane of the drawing, there are a large number of such pins 13 at intervals from one another.
  • a flexible hose 14 also extends in the longitudinal direction of the support 11. This is fastened to the support 11 and to a support member.
  • An extension 17 is inserted into a bore that is coaxial with the longitudinal axis 16 of the journal 13. This consists of an elastic, flexible material. 18 with a sleeve is designated, in which the pin 13 is immersed. The pin 13 is tapered at its front end when immersed in the sleeve 18.
  • the carrier 11 In order, for example, to lift sleeves from the conveyor belt (not shown) and place them on the spindles, the carrier 11 is moved against the sleeves located on the conveyor belt in such a way that a pin 13 is inserted into the cylindrical interior of each sleeve 18. After the pin 13 has reached its maximum immersion position, the air pressure inside the hose 14 is increased. The latter thus expands against the pin 13, as a result of which the latter and the sleeve 18 are pressed against one another. As a result, the sleeve 18 of the pin 13 and this held adjacent piece of tubing. In this way, all the sleeves placed on the conveyor belt of the spinning or twisting machine can be gripped at the same time and placed on the spindles by a corresponding movement of the carrier 11.
  • extension 17 has the result that, in the circumstances just described, incorrect positioning of the extension 17 on the upper edge of the sleeve can occur. In this case, as the carrier 11 sinks further, the extension bends through in its free part. He pushes the sleeve 18 either in its correct position or to the side. As a result, costly damage cannot occur.
  • FIG. 2 shows a carrier 21 which carries a row of pins running perpendicular to the plane of the drawing, all of which are identical to the pin 23.
  • the pins are fastened by means of screws 22.
  • a portion extends away from the front, conically tapered section 26 Extension 27 further forward.
  • the extension consists of a coil spring.
  • the pin 23 is also surrounded by a jacket 28, the surface of which has a relatively strong adhesive power. This is intended to ensure that a sleeve pressed onto the pin 23 is held stronger than in a system, for example on a smooth metal surface.
  • FIG. 1 shows a carrier 21 which carries a row of pins running perpendicular to the plane of the drawing, all of which are identical to the pin 23.
  • the pins are fastened by means of screws 22.
  • a portion extends away from the front, conically tapered section 26 Extension 27 further forward.
  • the extension consists of a coil spring.
  • the pin 23 is also surrounded by a jacket
  • FIG. 3 in turn shows a carrier 31, a pin 33 fastened with a screw 32, a hose 34 and a support member 35 forms a uniform piece of material, is surrounded.
  • a unitary piece of material has the advantage of being relatively simple to manufacture.
  • the end of the extension 37 is rounded, so that when the end of the extension 37 strikes the edge of the sleeve, the extension 37 slides away and thus the sleeve moves away more safely.
  • FIG. 4 shows a carrier 41. Pins are fastened to this, each of which, like the pin 43 shown, has a cavity 46 delimited by a cylinder made of elastic material.
  • the pin 43 and the extension 47 also consist of a single piece of material in this embodiment.
  • the carrier 41 has a chamber 44 extending over its entire length.
  • Each of the cavities 46 of the pins 43 arranged in the longitudinal direction of the carrier is connected to the chamber 44 via the channel 45.
  • the front end of the extension 47 is delimited by a surface which is oblique to its longitudinal axis. With this last-mentioned embodiment, the sliding of the extension 47 is again facilitated.
  • the pins 43 are immersed in the cylindrical interior of the sleeves. D a-raufhin the air pressure is increased in chamber 44, thereby also increases the air pressure in the cavity 46: Since the walls of the pins 43 are elastic, they expand thereby laterally so far out that they are on the inner walls of the sleeves, in which the pins 43 are immersed, come to rest and pins and sleeves are pressed together. These sleeves can thus be gripped and transported.
  • the extension 47 results in the mode of operation described with reference to the preceding exemplary embodiments. However, this embodiment is not primarily about avoiding damage to the carrier. An impact of the front end of the pin 43 on the upper edge of a sleeve in the absence of an extension 47 primarily results in the formation of cracks on the pin 43. As a result, the excess pressure in the chamber 44 also collapses, which among other things entails costly business interruptions.
  • the extensions 17, 27, 37, 47 preferably have the following characteristics: the length of the piece, which from the front apfenende Z extends away to the front, is at least equal to 1/10 and at most equal to half the stem length. Their elasticity is between 25 ° and 90 ° shore. They are advantageously made of rubber or thermoplastics.
