Definitions

  • the shingling conveyor belts revolve in normal operation at a speed which is lower than the machine speed and forward the workpieces to respective upper and lower collecting conveyor belts, which are provided with devices for forming stacks of workpieces.
  • the shingling belts are driven at a low speed, which ensures a satisfactory conveyance to the stack-forming device and is independent of the speed of the machine.
  • Said low speed of the shingling belts is so selected that the workpieces arriving on the shingling belts are spaced apart by a distance d and the workpieces are shingled on the shingling belts when the machine is running at a higher speed
  • the speed of the shingling belts is automatically controlled in such a manner that after an increase of the speed of the machine from a low value almost to a value at which the workpieces would closely succeed each other on the shingling belts the speed of the latter is suddenly reduced to such a value that the workpieces are shingled on the shingling belts, whereas a deceleration of the machine from a high speed almost to a value at which the shingling ofthe workpieces on the shingling belts would cease results in a sudden increase of the speed of the shingling belts to such a value that the workpieces arriving on the shingling belts are spaced apart.
  • FIGJO l C1 C2 1
  • the shingling belts can be driven at a certain minimum speed, which is independent of the machine speed and ensures a satisfactory conveyance for a formation of stacks, even when the bagmaking machine is moving at a low speed.
  • the tube sections moving on the shingling belts in succession are spaced apart whereas they will be shingled on the shingling belt and dropped from the latter in shingled form onto the collecting conveyor belt when the machine is moving at a higher speed, particularly at the usual speed.
  • the workpieces will then be shifted on' the collecting conveyor belt relative to each other as they strike the hinged stop plate.
  • the realization of the abovementioned concept of the invention necessitates an automatic control of the speed of the shingling belts in such a manner that the acceleration of the machine from a low speed results in a sudden reduction of the speed of the shingling belts just before the workpieces closely succeed each other on the shingling belts and this sudden reduction has the result that the workpieces are shingled on the shingling belts, whereas the deceleration of the machine from a high speed results in a sudden increase of the speed of the shingling belts just before the shingling of the workpieces on the shingling belts ceases, and this speed increase results in a deposition of workpieces in spaced apart relation on the shingling belts.
  • the speed of the shingling belts is so high when the machine is running at a low speed that a formation of stacks on the succeeding collecting conveyor belts is ensured, the speed of the shingling belts when the machine is running at a high speed is so low that the paper tube sections discharged at a high velocity are sufficiently braked and a satisfactory formation of stacks is ensured also under this condition, and, particularly, the transition from one speed of the shingling belts to the other will be effected without a disturbance.
  • the change of the speed ofthe shingling belt which is to be changed in speed first must be effected at a time which precedes by a full stack-forming period the time when the close succession of workpieces would be obtained so that the speed of the other conveyor belt can also be changed in time before that condition obtains, or, in accordance with another proposal of the invention, the speed of the machine must be maintained constant from the change of the speed of the first shingling belt to the change of the speed of the second shingling belt. This means that the increase or decrease of the speed of the machine is blocked until the speed of both shingling belts has been changed.
  • the change of the speed of the shingling belts may preferably be initiated by an actuating element, which is controlled by the machine speed and may consist of an electric generator tachometer, which is coupled to the means for driving the machine and cooperates with a suitable electric con troller.
  • the speed of the shingling belts is increased after the sudden deceleration when the speed of the machine is increased further and the speed of the shingling belts in this speed range is always kept below the discharge velocity of the machine.
  • the overlap of the shingled tube sections on the shingling belts will not be so large, even at a very high production rate of the tube-making machine, that the smooth conveyance by the collecting conveyor belts into engagement with the hinged stop plates will be endangered.
  • the drive which is independent of the machine is imparted by an electric motor which operates at a constant, preferably adjustable speed, and the operation of the shingling belts during the highspeed operation of the machine is preferably derived from the means for driving the machine so that additional drive means are not required during normal operation.
  • the operation of the shingling belts may be independent of the operation of the machine when the same is running at a high speed when a predetermined speed of the shingling belts is of primary significance rather than the overlap of the shingled workpieces.
  • the means for driving the shingling belts independently of the machine are connected to the drive pulleys for the shingling belts by clutches, preferably solenoid clutches, which are disengageable and/or engageable by a control signal in response to the machine assuming a limiting speed, and the further drive means are connected to the drive pulleys for the shingling belts by freewheel clutches.
  • clutches preferably solenoid clutches
  • the clutches between the electric motor and the drive pulleys for the shingling belts are disengaged, e.g., in that the solenoid clutches are deenergized by a switching device controlled by an electric generator tachometer, whereafter the drive pulleys for the shingling belts are automatically driven by the freewheel clutches, which previously trans mitted no torque but acted as overrunning clutches.

In the graph of FIG. 6, the ratio of the machine speed v to the belt speed V is still constant. In the graph of FIG. 9 that ratio will change as the machine speed increases.
