Definitions

  • ABSTRACT third shaft which is coupled to the second shaft and which is provided with at least one gearwheel which can. roll down along a toothed rack path which consists of two parallel toothed racks which are connected by two semi-circular gear rings.
  • the invention relates to a paper stacker, comprising a paper collecting device and a paper feed device which is arranged thereabove and which comprises a rigidly arranged drivable first shaft which is coupled to a second shaft which is capable of performing a swing ing movement with respect to the first shaft.
  • a paper stacker comprising a paper collecting device and a paper feed device which is arranged thereabove and which comprises a rigidly arranged drivable first shaft which is coupled to a second shaft which is capable of performing a swing ing movement with respect to the first shaft.
  • at least the second shaft being provided with at least two paper tractors which are provided with pins which can engage in a perforation track provided in the paper.
  • a paper stacker of the kind set forth is known from US. Patent Specification No. 3,464.6 l 0.
  • the paper feed device consists of two paper tractors which are provided with pins which engage in perforation tracks, the said tractors being guided over two shafts, the first of which is driven and the second of which performs a swinging movement.
  • the swinging movement is achieved by coupling the second shaft, via a cranck drive shaft mechanism, to a wheel which is coupled to thefirst shaft via gearwheels.
  • a relationship is thus produced between .the advancement of the paper andthe swinging movement.
  • This relationship The fixed relationship between paper speed and' swinging movement means that this known device can only process one kind of paper with a given distance between the folds. For paper having a different distance between folds, other gearwheels and a different cranck drive shaft mechanism must be used.
  • the invention has for its object to provide a paper stacker by means of which all distances between folds can be dealt with in a very simple manner.
  • the paper stacker according to the invention is characterized in that the second shaft is connected via at least one lever to a third shaft which is coupled to the second shaft and which is provided with at least one gearwheel which can roll down along a toothed rack path, consisting of two parallel toothed racks which are connected by two semicircular gear rings, the distance between the semicircular gear rings being adjustable.
  • the stroke of the swinging movement of the second shaft can be accurately adjusted, for example, to be equal to the distance between two folds.
  • the swinging frequency is automatically adapted in the correct ratio.
  • FIGS. 1 and 2 diagrammatically show the principle of a paper stacker in two mutually perpendicular crosssectional views.
  • FIGS. 3 and 4 diagrammatically illustrate another embodiment of a paper stacker.
  • the reference 1 in FIGS. 1 and 2 denotes a paper collecting bin.
  • This bin is arranged on a number of springs 2 of a construction such that under the influence of the weight of the collected paper the bin is lowered so that the paper level always remains substantially the same.
  • This mechanism comprises a first shaft 4 which is connected to an electric motor 6 via a coupling 5.
  • the shaft 4 Provided on the shaft 4 are two pulleys 7 and. 8, on which belts 9 and 10 are guided, each of which is provided with a number of pins 11 and 12, respectively.
  • the belts 9 and 10 are further guided over two pulleys l3 and 14, respectively, which are provided on a second shaft 15.
  • the second shaft 15 is journalled on the first shaft by way of two levers 16.
  • Also provided on the second shaft is a pulley on which a belt 18 is guided which further runs over a pulley 19 on a shaft 20.
  • Both ends of this shaft 20 are connected to the shaft 15 by an arm 21, the shaft 20 being provided on both ends with a gearwheel 22.
  • This gearwheel 22 cooperates with a toothed rack path, having inner toothing and consisting of two parallel toothed racks 23 and 24 which are provided in a frame 25, and two semi circular gear rings 26 and 27 which constitute a connection between the ends of the toothed racks 23 and 24.
  • the gear rings 26 and 27 are arranged to be slidable in the frame in the longitudinal direction of the toothed racks 23 and 24, so that the distance between the gear rings can be adjusted as desired.
  • the frame 25 is furthermore provided with a race 28 on which a wheel 29, connected to the gearwheel 22, rolls down.
  • the gearwheel 22, the toothed rack path 25, 24, 25 etc. can be omitted on one side of the shaft 20, so that a guide is present on only one side.
  • the paper denoted in the drawing by a broken line 30 and provided with folds which are situated at a regular distance from each other, engages pins 11, 12 on the belts 9, 10 via perforation tracks.
  • the motor 6 drives the shaft 4.
  • the pulleys 7, 8 drive the belts 9 and 10 which in turn drive the pulleys 13, 14, and hence the second shaft 15.
  • a plate 31 prevents the paper from coming loose from the pins ll, 12.
  • a pulley which is coupled, via a belt 18, to a pulley 19 on the shaft 20.
  • the shaft 20 will also be driven so that gearwheel22 starts to roll down along the toothed racks 23, 24 and the gear rings 26, 27.
  • aswinging movement. is imparted to the second shaft 15, the stroke length thereof corresponding approximately to the distance between the gear rings 26 and 27.
  • the adjustment can be such that the stroke is equal to the distance bet-ween the folds in the paper, so that this paper is neatly folded in the bin 1.
  • the stroke can alternative'ly be slightly smaller than the distance between folds.
  • the stroke and the frequency of the swinging movement can be very readily adapted to this new distance between the folds by readjustment of merely the distance between the gear rings 26 and 27.
  • the stroke as well as the frequency are thus adapted to the newsituation. It is thus possible to handle any kind of paper by means of this device.
  • the adjustment of the rings 26 and 27 can be manually effected or by means of a displacement mechanism such as, for example, a threaded spindle and a nut on each gear ring.
  • H68. 3 and 4 show a slightly different embodiment of a paper stacker in which the components which also form part of the device shown in FIGS. 1 and 2 are denoted by the same reference numerals.
  • This device differs with respect to the device shown in FIG. 1 in that the paper tractors l1 and 12 have a different construction
  • paper tractors 33 and 34 which are provided with pins are guided over pulleys 35 on shaft 15 and pulleys 36 on an auxiliary shaft 37 which is journalled in the arms 16.
  • Another advantage of the mechanism according to the invention is that the paper tractors 9, l and 33, 34,
  • a paper stacker for prefolded paper comprising a paper collecting device and a paper feed device which is arranged thereabove and which comprises a rigidly arranged drivable first shaft which is coupled to a second shaft which is capable of performing a swinging movement with respect to the first shaft.
  • at least the second shaft being provided with at least two paper tractors which are provided with pins which engage in a perforation track provided in the paper, characterized in that the second shaft is connected, via at least one lever, to a third shaft which is coupled to the second shaft and which is provided with at least one gearwheel which can roll down along a toothed rack path consisting of two parallel toothed racks which are connected by two semi-circular gear rings, the distance between the semi-circular gear rings being adjustable.
  • a paper-stacker for prefolded paper comprising a paper collecting device and a paper feed device which is arranged ther'eabove and which comprises a rigidly arranged drivable first shaft; a isecond shaft coupled to said first shaft and, capable" of performing a swinging movement with respect to p I the first shaft; at least two paper tractors provided on at least the second shaft 7 and which are provided with pins engagingin aperfor'ation track in the paper, a third shaft coupled to saidsecond shaft by at least onelever, at least one gearwheel” providedon said third shaft which can roll I r down along a toothed rack path of two parallel toothed racks which are connected by two semi-circular gear rings, the I distance betweenthe semi circular gear rings being adjust.
