Definitions

  • PATENTEDJANISIQH M 3556518 INVENTQRS Friedrich F'rnz BROCKMULLER goyke J NEMANN theirATTQRNEY lh machines for processing paper and plastics material sheeting, e.g. in tube-making machines,which are used in the manufacture of bags, it is usual to supply counted sets of work pieces, which exit from the machine at a high speed, to upper and lower delivery stations in alternation. To this end, the sections are caused to move over a deflector, which suppliessets of the desired number of workpieces in alternation to upper and lower belt conveyor systems.
  • the deflector must be shifted at very high speed.
  • the shifting operation must be initiated while the end of the preceding workpiece has left the deflector and must be terminated before the next workpiece reaches the deflector.
  • the shifting operation In a high-duty tube-making machine, e.g., the shifting operation must be performed within less than l /l second. Besides, the shifting operation must be most precisely the lever toward the other deflector position and said lever is I synchronized with the cycle of the machine, independently of the speed ofthe machine;
  • This object is accomplished according to the invention in that a clutch which is engageable electromagnetically, hydraulically or pneumatically is provided between the lever for shifting the deflector and a mechanical shifting means which performs a shifting I movement in each machine cycle, and said clutch when engaged transmits the shifting movement to the lever for shifting the deflector.
  • the clutch is engaged, e.g., in response to an electric pulse, which isdelivered from a settable repeating counter, which is coupled to the machine.
  • a device for engaging the clutch e.g., a solenoid
  • a solenoid is preferably arranged to change the position of a driver in such a manner that the linkage connected to the lever for shifting the deflector engages the driver of the shifting device during the next following shifting movement of the shifting device.
  • the clutch can be shifted at any time during the cycle and such shifting will not involve a shifting of the deflector at an improper time.
  • the shifting of the clutch could begin one half of a cycle before the time when the deflector is to be shifted.
  • the shifting of the deflector may be initiated by a solenoid or an electric clutch or a hydraulic or pneumatic piston-cylinder unit of normal type although such means operate with a relatively long delay or a long stroke time.
  • the lever for shifting the deflector is under the action of a work storage device urging locked by a latch, which is releasable by the shifiing movement.
  • the deflector is not shifted by the shifting member, which performs its shifting movements in synchronism with the cyclic operation of the machine, but the shifting of the deflector is only initiated by said shifting member and the linkage which is connected to the lever for shifting the deflector, which initiation releases the latch which is in locking position at the time.
  • the actual shifting movement can then be performed at very high speed by the work storage device, e.g., by one or more tension springs which are highly prestressed.
  • the deflector can be pivotally moved into position 1' shown in dash-dot lines by a deflector shifting lever 3, which is also secured to the shaft 2.
  • a deflector shifting lever 3 which is also secured to the shaft 2.
  • the tube sections 38, 39 move in the direction of the arrow over the deflector from the left to the right.
  • the conveyor rollers or belts required for this movement of the tube sections are not shown.
  • the deflector must be shifted from position 1 to 1 or vice versa at the instant at which a gap x between successive tube sections is just over the tongue of the deflector l and must be terminated before the leading edge of the following section has reached the tip of the tongue of the deflector l.
  • the lever 3 is operated by a rod 6 and a lever 4, which is pivoted to the machine frame by the pin 5.
  • the mechanical operation of the deflector is initiated by an eccentric disc 7, which revolves in the direction of the arrow in synchronism with the cyclic operation of the machine so as to perform exactly one revolution for each tube section 38 or 39 travelling over the deflector l.
  • the amount of the eccentricity of the crankpin 8 is adjustable in known manner by a groove 7 which consists preferably of a dovetail groove.
  • the crankpin.8 is shown in four positions 8a, 8b, 8c, and 8d, which are spaced 90 apart in the direction of revolution of the eccentric disc 7, and in a position 8 on the left of position 8a.
  • the angular position of the eccentric disc relative to the cyclic shaft of the machine is preferably selected so that the pin 8 is in position So when the trailing edge of the tube section 39 is just over the tip of the deflector tongue 1, i.e., at the time when the shifting operation must be initiated. in this position, the rod 9 and with it the entire shifting device has the highest velocity.
  • the rod 9 transmits the movements of the crankpin 8 as reciprocating movements to the lever 10, which is pivoted to the machine frame by a pin 11.
  • the lever 10 transmits the reciprocating movement to the rod 12, which is slidable in the guide 13.
  • the guide 13 is rotatably mounted in the rod head 14, which is secured in the stroke rod of the solenoid 15. The latter is shown in its deenergized condition.
  • the rod 12 carries centrally an enlarged portion having an edge 16, which can freely reciprocate, when the solenoid 15 is in the position shown in the drawing, under the pressure member 17, which is secured to the three-armed lever 18.
  • the latter is pivoted to the machine frame by the pin 19.
  • One arm of the lever engages the stop screw 40, which is secured in the machine frame, so that a rotation to the left is prevented.
  • the rod 12 is moved to the right and the solenoid 12 can attract further at the instant at which the pressure member 17 releases the edge 16 of the rod 12. This is effected approximately at the time at which the pin 8 is between positions and 8b.
  • the rod 12 is displaced to the right and the edge 16 of the rod 12, which is raised by the solenoid, bears on the pressure member 17 and imparts to the pressure rollers 20 and 21 a rotation to the right.
  • a latch lever 22 engages the pressure roller 20
  • the latch lever 22 is rotatably mounted in the machine frame by a pin 28.
  • a tension spring 24 is secured atone end to the latch lever 22 and at the other end to the machine frame and urges the latch lever 22 firmly into engagement'with the pressure roller 20 so that the three-armed lever 18 is urged against the stop screw 40. If the three-armed lever 18 is turned to the right as is described above, it will bear by the roller 20 onto the latch lever 22 so that the latch 26 thereof is raised to release the right upper edge of the lever 4.
  • a pin 34 is secured to the lever 4.
  • the hanger 35 is pivoted to the pin 34 and under the action of two highly stressed tension springs 30, 31.
  • tension springs 30, 31 other work storage devices may be used, such as cylinders containing compressed air, or the like, provided that they operate without inertia and without delay.
  • the tension springs 30, 31 now pull the lever suddenly against the stop screw 36, which is secured to the machine frame.
  • the rod 6 is moved to the right and the tongue of the deflector 1 is shifted upwardly. This operation is performed very fast under the action of the prestressed springs 30, 31 and at the instant which is exactly determined by the position of the eccentric disc 7 and is independent of the time when the solenoid l attracted during the cycle.
  • the tension springs 30,31 are secured to the rocker lever 32, which is pivotally'movable about the pin 33 t0 the position 32a by a gear motor or a hydraulic or pneumatic drive.
  • This operation is performed after the abovedescribed shifting operations and is controlled, e.g., by a timelimit relay, which is controlled by the'pulse that is applied to the solenoid and to said time-limit relay at the same time.
  • the tension springs 30, 31 are stressed in the opposite direction so that the device is now prepared for the downward shifting of the deflector tongue.
  • the latch 27 is lifted in the manner which has been described above so that the rotation of the lever 4 to the right against the stop screw 37 is initiated and results in a downward shift of the deflector 1.
  • the pulses applied to the solenoid 15 may be transmitted by an adjustable repeating counter of knowntype arranged to make contact in response to a desired count.
  • the duration the time of arrival of the pulse may be variable within wide limits.
  • the solenoid 15 may attract although the shifting of the deflector is not initiated until the edge 16 moves from the left to the right for the next time. It will also be sufficient if the solenoid is deenergized at any desired time during the subsequent return movement of the rod 12. The timej'between two shifts of the deflector is available for the shifting of the rocker lever 32 so that this movement may also be slowly performed.
  • Apparatus for shifting a deflector in a machine 7 for processing paper or plastics riiaterial sheeting, preferably a tube-making machine, so as to change thepath of travel of the workpieces having a mechanical shifting means and a lever on which said shifting means acts to move the deflector, characterized in that a clutch which' is engageable electromagnetically, hydraulically or pneumatically is provided between the lever for shifting the deflector and a mechanical shifting means which performs a shifting movement in each machine cycle, and said clutch when engaged transmits the shifting movement to the lever for shifting the deflector.
