Definitions

  • a presettable counting device such as is usable in a copying apparatus includes a rotating element set to rotate through a certain angle for each cyclic operation of the device.
  • a presettable counting wheel is spaced from the rotating elements and their axis are disposed in parallel relationship. Number panels in a numbered sequence are provided on the circumferential periphery of the counting wheel commencing from a zero position.
  • a spring drive member biases the counting wheel toward the zero position.
  • a toothed locking wheel is connected to the counting wheel and locking levers extend between the toothed locking wheel and a multiple cam on the rotating element for holding the counting wheel and effecting its stepwise return to the zero position.
  • a signalling device can be incorporated into the counting device to indicate when the counting wheel has returned to the zero position.
  • the preferred embodiment relating to copying apparatus, is based on the fact that occasionally several copies must be made from one original, and this number of copies may vary from one original to another. Although it is known to provide a comparatively complicated device which controls automatically the manufacture of several copies, particularly in apparatus in which the original may remain on the exposure plate, this solution is very expensive and requires a type of apparatus in which the original fulfills no switching function.
  • the rotating element has a multiple cam, and preferably a twin cam arrangement with at least one raised cam on adjacent cam tracks, and collaborating with at least one raised cam on adjacent cam tracks, and collaborating with at least two alternatively disengageable locking levers which free a counting wheel with at least one associated locking wheel intermittently from its toothing, wherein the assembly of counting wheel and locking wheel is spring biased in the direction of resetting the counting wheel into a zero position and the free rotation of the counting wheel against the spring drive by means of the engaging locking levers is provided.
  • the invention requires only one rotating element because the locking wheels and the counting wheel, having number panels on its circumference, may be made in one piece so that only a locking lever arrangement and a spring for driving the counting wheel must be additionally provided.
  • this construction is very complex and particularly suitable for copying apparatus because the counting wheel may protrude with one part of its periphery through an opening in a housing wall, which is provided with a pointer, permitting a number panel to be selected, wherein the operating element is the protruding section of the periphery of the wheel which may be provided with a knurling.
  • the toothing of the at least one locking wheel is substantially sine shaped, and permits an adjustment under the locking levers in differentdirections, wherein the force of the locking levers is so dimensioned, by weight or spring, that they retain the counting wheel against the spring drive.
  • the toothing of the at least one locking wheel is sawtoothed shape and blocks the random rotation of the counting wheel with engaging locking lever in the direction of a resetting of the counting wheel by the spring drive.
  • the invention provides a resetting by means of a one way coupling between the said at least one locking wheel and the counting wheel, wherein the coupling remains in engagement under the bias of the spring drive, but permits the adjustment of the counting wheel between the two elements of the coupling in the direction of the spring drive.
  • this one way coupling is a spring-loaded toothed coupling with saw-toothed-shape teeth in which the sloping flank permits the adjustment in-the direction of the spring drive, and wherein the coupling spring is strong enough to maintain the engagement under the force of the spring drive in a slip-free condition.
  • the rotational path comprising one or two teeth of a locking wheel corresponds to one number panel of the counting wheel, the periphery of which carries several successive number panels. If only one locking wheel with a single toothing is used for two locking levers, each panel comprises two tooth divisions.
  • the raised cams for the different locking levers are offset relative to each other, for example in the case of two locking levers and two locking wheels by half the angle through which the rotating element rotates with each working stroke. In the case of several elements, the offset would amount to a corresponding fraction.
  • the construction with two locking levers is the particularly preferred embodiment of the invention, in which the movement of the counting wheel through one panel, occurs in two steps.
  • the number of steps for one number panel would correspond to the chosen number of elements.
  • this construction may have special advantages where certain control steps are to be performed during one working stroke.
  • the locking levers have lateral crossmembers directed towards the counting wheel or a disk connected therewith and provided with cams for the crossmembers in a position such that after the passage of the digit 1 during the counting, they lift the locking levers out of engagement with the associated locking wheel or wheels; a stop is provided which stops the rotation of the counting wheel in the zero position.
  • the abutment on the counting wheel cooperates with a stop which engages when the locking wheel reaches a zero position.
  • This engagement may be direct or indirect. Stopping of the counting wheels indicates at least the completion of the required number of strokes by means of the pointer to a certain number panel. The stop may, however, also block the connected apparatus.
  • the signalling equipment mentioned in the following may be optical or acoustic and actuable as a function of the counting wheel running into the zero position.
  • a preferably acoustic signalling device in the shape of a bell mounted, for example, on a wall of the housing in which the clapper, spring loaded by a spring or by the weight distribution so as to return into the starting position, is a pivoting lever and extends either into the path of the stop or may be actuated by a cam of the rotating element in conjunction with a cam plate on the counting wheel.
  • the clapper has an elastic leg and the stop forms an abutment for a rigid leg of the clapper which engages the abutment after striking the bell and thereby stops the counting wheel.
  • the cam disk is provided in concentric arrangement to the counting wheel and has a step-shaped recess corresponding to the zero position of the counting wheel and adapted to receive a lug of the elastic clapper guided by spring force along the revolving element and along the cam disk, causing to strike the bell when running into the recess and being released by its cam.
  • the locking levers are pivoting levers and are biased by springs pulling them into engagement.
  • the cam is provided with two raised cams in two parallel cam tracks, offset circumferentially through 180, and in which case two locking wheels and two locking levers are provided.
  • FIG. 1 shows a side elevation of the counting device according to the invention, with one wall of an apparatus being sectionalized along the line [-1 in FIG. 2;
  • FIG. 2 is a plan view of FIG. 1 with some parts omitted;
  • FIG. 3 is a side elevation of another embodiment of the invention, showing merely the parts necessary for explaining the same;
  • FIG. 4 is a plan view of FIG. 3;
  • FIG. 5 shows diagrammatically an apparatus and explains the arrangement of the counting mechanism in a copier
  • FIG. 6 shows diagrammatically the construction of an apparatus and explains the arrangement of the counting mechanism.
  • a mounting arrangement 1 comprises, in integral construction, a counting wheel 2 and locking wheels 3 and 4.
  • the locking wheels are shown to have different diameters, it is, of course, equally possible to use locking wheels with the same diameters.
  • the locking wheel 4 has a shaft extension 5 which is affected by a spring drive 6, the spring being, for example, wound by means of a band 7 about the shaft extension and being fixed at 8. As may be seen from FIG. 2, the counting wheel is not in the zero position and the spring 6 is therefore tensioned. The other end of the spring is fixed to a frame as at 8.
  • the actuating arrangement by means of the spring 6 has merely the object of rotating the counting wheel through the maximum counting distance, that is to say, once through 360.
  • the circumference of the counting wheel is provided with number panels, 9, 10, 11.
  • the dimensions of these number panels in the direction of the circumference is related to the spacing between the teeth of the locking wheels.
  • One tooth spacing of the toothing 12, I3 corresponds to the length of a number panel in the direction of the circumference, for example the distance between the teeth 14 and 15.
  • the toothing l2, 13 is so toothed shaped so that the steep flank of a tooth is leading during the actuation by the spring 6.
  • Two pivotable locking levers 17, 18 are mounted in a mounting 16 in a frame and have at their free ends pawls 19, 20 which engage into the toothing and may be formed in accordance with the recesses between the teeth.
  • the locking levers are affected by springs 21, 22 which pull the locking levers against a double cam 23 arranged on the intermittently rotating element 24, for example a shaft, and rotating in this embodiment through 180 for each working stroke.
  • the twin cam has two camtracks 25, 26 each with a raised portion 27, 28 which are offset relative to each other through 180.
  • the counting wheel protrudes with a portion 29 from an opening 30 of a housing wall 31. Adjacent to the opening 30 there is a marker, such an arrow 32, indicating one number panel.
  • the number panels may be located between two knurled strips 33, 34 acting simultaneously as actuating elements for selecting the number of working strokes or for setting the number wheel 2.
  • the number wheel has a stop 35, e.g., in the shape of a pin, and corresponding to the zero position.
  • a collaborating abutment is provided in this embodiment in conjunction with a signaling device to be described further below.
  • the counter wheel 2 is rotated in a clockwise direction, as viewed in FIG. 1, until the desired number of strokes appears opposite the marker 32.
  • the pawls 19, 20 slide over the toothing l2, [3.
  • the twin cam 23 is rotated through 360. During this, first the pawl 17 is released enabling it to engage in front of the tooth 36. Next the raised cam 28 lifts the pawl lever l8, so that the assembly of counting wheel 2 and locking wheels 3, 4 is rotated until the tooth 36 engages. During the further rotation the raised cam 28 releases the locking lever 18 which engages in front of the tooth 37.
  • the counting wheel 2 has cams 38, 93 and the locking levers 17, 18 have crossmembers 89, extending laterally towards the counting wheel and into the path of the earns 38, 93. It should be noted that these earns 38, 93 are on a smaller radius than the stop 35.
  • the cams 38, 93 are so located that when the number panel 1 has passed the marker 32 the pawls 19, 20 are lifted out of engagement with the locking wheels, enabling the spring 6 to rotate the counting wheel until the stop 35 meets its abutment and the whole device is stopped.
  • the abutment 91 is formed in conjunction with an acoustic signaling device which is triggered off when the number panel 0 is released at the marker 32.
  • the signalling device is a bell 39 arranged on the housing wall 31, and having a clapper 40 in the shape of a two-armed angled lever. This lever is mounted at 41 and is acted upon by a spring 42 tending to pull the clapper into a starting position against a stop 92.
  • the clapper has one elastic leg 43 which is held in front of the bell 39 in the inoperative position. The end of the other leg 40, remote from the leg 43 and made of a rigid material, projects into the path of the stop 35.
  • this embodiment comprises a unit consisting of a counting wheel 58, a locking wheel 59 and a one way coupling 60, mounted rotatably on a spindle 62, located, for example, in a housing 61.
  • This unit is pushed axially by a spring 63 against an abutment 64 on the spindle 62.
  • the counting wheel 58 is also provided with a cam plate 64, serving to actuate a clapper 65 for a bell 66.
  • a spring drive 67 is provided in connection .with a disk 68 and tends to return thecounting wheel into the zero position.
  • the coupling halves 69, 70 of the coupling 60 engage by means of saw-toothed-shape coupling teeth, the shape of which is such that when the locking wheel 59 is standing still, the counting wheel can be rotated in the direction of the spring drive 67 so as to return an excessive adjustment.
  • the spring 63 yields.
  • this construction comprises a cam 71 with two raised cams 72, 73 arranged on parallel tracks and cooperating with two locking levers 74, 75 which are pivotable in a mounting 76 and are pulled by springs 77, 78 (not shown in FIG. 4), into engagement with the locking wheel 59 or the raised earns 72, 73.
  • the locking pawls 79, 80 of the locking levers are offset relative to each other by half a tooth spacing, so that they engage successively and during one revolution of the cam or of the shaft 71 the counting wheel 58 is advanced by one tooth spacing.
  • the clapper 65 pivotable about a pivot 81, is associated with a raised cam 82 on the shaft which pivots it against the force of a spring 83 during the passage of each number panel.
  • the spring 83 pulls a lug 84 arranged on the clapper 65, against the cam plate 64. During this the resilient clapper may be deflected.
  • the cam plate has a recess 85 with a radially stepped flank 86 and a shallow rise 87.
  • the connected apparatus When the counting wheel 58, with the number panels, is adjusted in a clockwise direction, causing the spring drive 67 to be tensioned, the connected apparatus is in the starting position in which the raised cam 82 holds the clapper outside the cam plate 4, permitting the stepped flank 86 to bypass the lug 84.
  • the lug comes to rest on the periphery of the cam plate 64, so that the clapper 88 does not reach the bell.
  • the step flank 86 has passed the lug and the clapper, released by the cam 82, engages into the recess and strikes the bell.
  • the lug 84 may also be used as end stop if the recess 85 is suitably shaped.
  • the shaft 24 in FIGS. 1 and 2, or 71 in FIGS. 3 and 4 corresponds to the so-called switching roller 44 in front of a stack 45 of sheets of copying paper.
