Definitions

  • ABSTRACT An arrangement for controlling the speed of conveyors which convey bottles to and from a bottle filling machine in which the conveyors are so supported as to be yieldable under the weight of bottles thereon. Detectors detect the vertical movement of the conveyors and control the speed of the conveyor drive motor so that downward movement of the conveyors slow down the motor while upward movement of the conveyors speed up the motor. The control of the drive motor is such that downward movement of the conveyor taking bottles away from the filling machine will cause the motor to slow down regardless of the vertical position of the conveyor which supplies bottles to the filling machine.
  • the present invention relates to a device for controlling the working speed of bottle treating machines, especially filling machines, which are interconnected by conveyors. in conformity with the weight of the bottles transported on the conveyor.
  • Control devices are disclosed in German Offenlegungsschrift No. 1,954,299 dated May 13, l97l which effect a speed control of the driving motor of bottle treating machines in conformity with the bottle weight while the feeding conveyor preceding the machine or a portion of said feeding conveyor forms a weighing device.
  • German Offenlegungsschrift No. 2,046,280 dated Mar. 23. 1972 discloses a design which starts with the bend of the feeding conveyor and provides a pulse emitter actuated by the bend and is in the form of a pressure measuring device. The pulses thereof bring about a change in the speed of the driving motor.
  • the pressure measuring device is positively arranged between two adjacent supports of the feeding conveyor and statically considered represents a beam on three supports which represents an indefinite system and does not permit a precise speed control. This is due in particular to the fact that the supports of the feeding conveyor are not firmly anchored in the ground and their supporting points are in indefinite positions.
  • an object of the present invention to provide a control device which will overcome the above mentioned drawbacks and which will represent an improvement with regard to its response behavior as well as its ability of being controlled and which with regard to the speed control also takes into consideration the bottles which are being conveyed to the treating machine as well as the bottles which are being withdrawn therefrom.
  • FIG. I diagrammatically illustrates a bottle treating machine with preceding and following conveyor paths and with built-in contact-free pulse emitters
  • FIG. 2 illustrates a pulse emitter associated with the feeding conveyor.
  • FIG. 3 illustrates a pulse emitter associated with the withdrawing conveyor.
  • the present invention starts with a control device with a pulse emitter arranged between two adjacent conveyor supports.
  • This pulse emitter is adapted to be influenced during the bottle transfer by the bend of the input conveyor while the pulse emitter controls the speed electrically or electronically.
  • the device according to the invention is characterized primarily in that contact-free pulse emitters are provided individually or combined into groups with the conveyor in a relationship preceding and following as arranged between two supporting pairs firmly anchored in the ground within the region of a sufficient conveyor path bend.
  • the device according to the invention is furthermore characterized in that there is provided a control element which evaluates the pulses of the pulse emitter of the preceding and following conveyor path and the speed governor is influenced thereby in such a way that when registering pulses of the following conveyor path, the speed of the machine drive is reduced regardless of the pulses emitted from the preceding conveyor or conveyor path.
  • the suggested positive connection of the conveyor path supports with the ground results in a beam on two supports which adopts definite static equilibrium positions and also adopts bends which are dependent only on the bottle weight and are suitable for the control.
  • the withdrawal conveyor of the machine into the control system and to equip the machine with contact-free impulse emitters.
  • one or more contact-free pulse emitters are arranged at the spacing of a plurality of support pairs of the preceding or following conveyor. For evaluating their pulses by the control element, the pulse emitters respectively associated with the conveyors are connected to each other.
  • the pulse emitters are designed as stroke measuring devices which respectively comprise a measuring element.
  • the foregoing in planes of different height are located opposite to each other and which furthermore comprise an actuating element each.
  • the measuring element is arranged on a horizontal beam of the conveyor frame between supports, and that the actuating element is provided on a fixed rail which is independent of the frame beam and is parallel thereto.
  • the actuating element may expediently comprise a head screw which is adjustably connected to the rail, said head screw having its head directed toward the measuring element.
  • the bottle treating machine illustrated in FIG. 1 represents a filling machine 10, which comprises a feed-in conveyor path 11 which feeds the bottles, for instance, from a cleaning machine, and which also comprises a with drawing conveyor path 12 which conveys the filled botties to a connecting machine, for instance, a closing machine.
  • the conveyor paths 11 and 12 are connected to the machine 10, and over their length are provided with supports which are firmly anchored in the ground 13.
  • the illustrated supports of the feed-in conveyor path 11 are designated with the reference numerals l4, 15, 16 whereas the supports for the withdrawing conveyor path 12 are designated with the reference numerals 17,18 and 19.
  • the contact- ,free pulse emitters 20, 21, 22, 23 are expediently designed as stroke measuring devices.
  • These strokes measuring devices each comprise a measuring element 25, which measuring elements face each other in planes of different heights and also each comprises an actuating element 26.
  • the measuring element 25 with which the measuring operation is based on a change in the properties of a magnetic field during the approach of a me tallic article, is fastened to a horizontal beam 27 of a conveyor frame within the region of a sufficient bend between a support pair l4, 15; 15, 16 and 17, 18; 18, 19,
  • the actuating element 26 is expediently arranged for adjustment as to height and is mounted on a fixed rail 28 independently of the frame beam 27.
  • the impulse emitters 20, 21 associated with the input conveyor path 11 have the measuring elements 25 electrically connected to each other and also connected to a control element 30.
  • a control element 30 is connected to each other and connected to the control element 30 to measure elements 25 of the pulse emitters 22, 23 of the withdrawing conveyor path 12.
  • the control element 30 is followed by a speed governor 31 known per se, which acts upon the drive motor 33 ofthe machine 10, which drive motor is equipped with a tacho generator 32.
  • This arrangement operates as follows: During normal operation, the bottles fed on the conveyor path 11 move into the rotating machine 10 and subsequently through the conveyor path 12 move to the next following treating machine.
  • the speed of the motor 33 will be increased or decreased accordingly through the intervention of the control member 30 and the governor 31. If circumstances bring about a back up of the bottles on the withdrawing conveyor path 12, the pulse emitters 22, 23 which operate in the same manner will respond due to the increased bottle weight.
  • the pulses of the pulse emitters 22, 23 are registered by the control element 30 which, independent of the continuing bottle feeding on the feeding conveyor path 11 and the thereby released pulses of the pulse emitter 20, 21, causes the governor 31 to reduce the speed ofthe motor 33.
  • the present invention is, by no means, limited to the specific embodi ment set forth above, but also comprises any modifications within the scope of the appended claims.
  • the device according to the invention is suitable for all vessel treating machines with preceding and following conveyor path and is adapted to be used in connection therewith with one or more contact-free pulse emitters between a support pair as well as between a plurality of support pairs of the feeding-in and withdrawing conveyor means.
