Definitions

  • the invention relates to a device for separating stacked flat workpieces, preferably stacked hose pieces, consisting of a web-like support frame rotatably mounted in a frame and provided with a drive, in which a row of suction cups is provided at a constant angle on a circular line concentric to its axis of rotation Rollers are rotatably mounted, the drive gears of which are driven via intermediate wheels mounted in the support frame by a central wheel fixed to the frame with the direction of rotation opposite to the direction of rotation of the support frame, from a stacked cassette so set on the envelope cylinders described by the suction rows that each suction row of each roller contains an exposed workpiece withdraws, and from a conveying device attached to the enveloping cylinder, which removes and further conveys the individual workpieces.
  • the stack-receiving stack cassette is located above the envelope cylinder described by the suction rolls, the stack to be separated being arranged on the suction rolls and additional support rolls arranged between the suction rolls, the same Support the envelope cylinder as described by the suction rollers.
  • This type of support is necessary in the known rotary feeder, so that each suction roll from the stack a lower exposed workpiece can be removed.
  • Rotary feeders are connected upstream of the sack making floor laying machines. Modern floor-laying machines have a high output, so that the rotary feeders must also be operated at a higher speed in order to feed the individual pieces of hose to the floor-laying machine with a correspondingly increased number of cycles. At higher speeds, however, the stack supported on the suction and back-up rolls of the rotary feeder vibrates so strongly that it is no longer guaranteed that the suction rows of each suction roll suck the lowest hose section safely at its front edge area, so that there is no separation or the piece of hose to be separated is only incompletely and possibly pulled off in an inclined position.
  • this object is achieved in that the stacking cassette completely holds the stack to be separated.
  • Such a complete holder is to be understood as one in which the stacks in the stacking cassette are no longer supported by the suction rolls and intermediate rolls themselves, but are held in the stacking cassette without support.
  • the stacking cassette is arranged below the supporting frame supporting the suction rolls, so that each row of suction cups sucks in the uppermost exposed workpiece of the stack to separate it. Since the stack is completely held in the stacking cassette, it remains at rest without vibrations, so that each continuous row of suction cups can suck in the upper exposed workpiece safely and in the correct position.
  • the base of the cassette supporting the stack is expediently designed to be liftable, so that the stack can be raised in accordance with the decrease in its height as a result of the separation of the workpieces.
  • the stacking cassette consists of a vertical shaft into which two pairs of rust-like tines protrude from opposite sides, of which the tines of each pair lie in the same horizontal plane and which penetrate each other in a lifting manner. and lowerable and out of the shaft and retractable into it. A new stack to be separated is placed on the lower tines of the pair of tines. This stack is then raised until it is in abutment with the upper stack in the singulation.
  • the tines supporting the upper stack are moved out of the shaft and lowered and retracted into the shaft so that they are ready to receive the next stack.
  • the guides carrying the rust-like tines and their drives are expediently arranged on the vertical strands of endless and reversibly driven traction means.
  • the stack of vertical sheets are arranged, at least two of which are opposite one another and provided with a drive which vibrates them.
  • the vibrating metal sheets align the individual workpieces of the stack in a straight line so that the upper workpiece can be sucked in the correct position by the continuous suction roll. Since the suction rows of the suction rolls move on cycloids, the passage of the suction rolls can be matched to the stack in such a way that the suction rows suck the workpieces to be separated, for example at reversal points where they have zero speed, on their front edges. In this way, a smooth and shock-free separation is guaranteed.
  • the conveying device which removes and further promotes the individual workpieces, consists of at least one rotatably mounted row of suction cups, which is driven intermittently in such a way that it sucks the workpieces approximately at a standstill when the row of suction cups rotating on a cycloid Suction rollers also pass through rest points in their reversal points.
  • the conveying device it is also ensured in the case of the further conveying device that the separated workpieces decreases almost at a standstill from the rotary feeder and takes over the further funding.
  • pulleys are freely rotatably mounted on the shaft of the suction row, which form the deflection pulleys of a family of parallel endless belts of a double belt conveyor, which conveys the isolated workpieces.
  • the endless belts running around the deflection pulleys interact with endless belts of a second conveyor belt which is clamped against the first set of endless belts.
  • the rotary feeder 1 shown in FIG. 1 consists of a support star 3 rotatably mounted in a machine frame, not shown, about the axis 2 and provided with a rotary drive, not shown, for example consisting of side disks of a web-like support frame, on which eight intermediate wheels 4 are freely rotatably mounted which mesh on the one hand with a fixed central wheel 5 and on the other hand with gears 6, which mesh on the shafts of the suction rollers 7, which are freely rotatably mounted in the support star 3.
  • Each of the suction rolls 7 is provided with a series of suction devices 8 along surface lines.
  • the rotary feeder corresponds to the rotary feeder known from DE-PS 12 77 655, to which reference is made for further illustration.
  • a stacking cassette 10 for receiving the stacks 11 to be separated is arranged in the machine frame below the rotary feeder.
  • the stacking cassette 10 consists of a stacking shaft, on the sides of which endless traction rollers are arranged around deflection rollers and driven rollers, on the strands 12, 12 'and 13, 13' facing the stacking shaft, guides 14, 14 'and 15, 15' for the Stacking shaft retractable and extendable rust-like tines 16, 16 'and 17, 17' are held.
  • the rust-like tines are provided with drives, not shown, on the basis of which they can be moved into and out of the stacking shaft 10 in the direction of the double arrows A.
  • the dreams of the endless conveying means carrying the guides are reversibly drivable in the direction of the double arrows B, so that the upper stack 11 is raised in accordance with the decrease in the stack height as a result of the separation and the lower stack 11 is placed against the upper stack and the upper rust-like tines are downward can be moved to accommodate a new batch to be created.
  • lateral vertical plates 20, 21 are arranged, which are set in vibration in the direction of the double arrows C by vibration drives, not shown, so that the ascending stack 11 are aligned straight.
  • the support star 3 rotates in the direction of arrow D, while the individual suction rolls are driven in the direction of arrow E.
  • the geometric relationships matched to one another in such a way that the rows of suction pads rotating on cycloids, in their reversal points, at which they have approximately zero speed, suck in the workpieces to be separated in the region of their front edges, as is indicated in FIG. 3.
  • the workpieces separated by the rotary feeder are transferred by the rotary feeder to the further conveyor 24.
  • This consists of a shaft 25 mounted in the machine frame, not shown, which is provided with two suction bores 26, 27, which are connected to a vacuum source via a rotary leadthrough, not shown. Rows of suction cups 28, 29 are placed on the shaft 25, offset from one another by 180 °, and the tubes carrying the suction cups are connected to the suction bores 26, 27.
  • the shaft 25 is driven via a belt 30 by a servo motor 31 whose speed can be controlled.
  • Pulleys 32 are freely rotatably mounted on the shaft 25, over which the endless belts 33 of the upper part of a double belt conveyor run, which interact with the belts 34 of the lower part of the double belt conveyor.
  • the servo motor 31 controls the shaft 25 in such a way that the suction rows 28, 29 remove the individual workpieces from the suction rolls 7 of the rotary feeder 1 at times in which the suction rows 8 in the reversal points of the cycloid on which they revolve, just about that Have zero speed. In this way, the workpieces can be removed from the suction rolls at approximately zero speed, so that a bumpless transfer is guaranteed.
  • the servo motor 31 accelerates the shaft 25 from standstill to the rotational speed of the double conveyor belt, so that the Workpieces can be taken along by the double belt conveyor in the correct position and without acceleration.
