Definitions

  • the present invention relates to a device according to the preamble of patent claim 1.
  • Such a device is known, for example, from DE-OS 25 18 374 (IPC B 65 H, published on December 11, 1975), which is essentially identical in content to US Pat. No. 4,274,623.
  • stable, coiled stacks can be produced from the flat structures, even if they occur in very rapid succession, the capacity of which is many times greater than that of conventional, essentially cuboid stacks.
  • Another advantage of the coiled stacks is that the scale formation, even if deformed, remains in the stack itself, which makes it possible to restore the scale formation immediately when the stack is dismantled.
  • the stacks that can be produced with the known device become comparatively very high, so that their handling, for example their internal transport and storage, is made more difficult.
  • the capacity of the stacks produced with the known device is not yet sufficient to accommodate, for example, the largest part of an edition of preliminary products of a newspaper or magazine.
  • the proposed device has the features defined in the characterizing part of patent claim 1.
  • each turn of the helix in turn consists of a spiral that runs alternately from the inside to the outside and from the outside in, preferably with several turns ( Spiral windings).
  • the diameter of the stack is increased, but its height is significantly smaller, while its content is enlarged on individual flat structures.
  • the device 10 shown in FIGS. 1, 1A and 2 are supplied with flat structures, here newspapers 11, by means of a single conveyor 12, which is only indicated schematically.
  • the individual conveyor 12 is described, for example, in CH-PS 592,562, which is largely identical in content to US-PS 3,955,667, so that a more detailed description is unnecessary here, especially since the individual conveyor 12 only shows its discharge end 13.
  • the newspapers 11 released at the discharge end 13 arrive at a transfer belt 14 which is driven in the same direction and essentially at the same speed as that of the individual conveyor 12.
  • a shingled stream is formed on the transfer belt 14 from the newspapers 11, in which the leading edge of each newspaper is its bundle or fold, which overlaps the trailing edge (flower) of the preceding newspaper.
  • the empty, returning run of the conveyor 15 leads vertically downward from the deflection roller 19 via a roller 21 arranged in the vicinity of the deflection roller 18, around a drive roller 22 and from there vertically upward around a further deflection roller 23 and again to the deflection roller 16 .
  • the deflecting rollers 18 and the roller 21 are mounted on a frame 24, from which frame also a boom (not shown) carrying the deflecting roller 19 at the outlet 20 starts.
  • the frame 24 is vertically guided, so corresponds in this regard to the auxiliary frame described with reference to FIG. 3A of DE-OS 25 18 374.8 with the reference number 58.
  • the vertical guide rails for the frame 24 are not shown.
  • the drive roller 22 for the conveyor 15 is connected via a chain 28 to a drive unit 29, the speed of which (in the embodiment of FIG. 1) is infinitely variable in a manner to be described and controlled.
  • the drive roller 27 is via a chain 30 coupled to a reversible drive unit 31, the control of which will be described later.
  • Both drive units 29, 31 are mounted on a platform 32 which projects laterally at the lower end of a vertical column 33 and is fastened to the latter.
  • the column 33 is rotatably supported at 34, 35 and 36.
  • a boom 37 is attached, the vertical guide rails (not shown) for the frame 24 extending between the latter and the platform 32.
  • a pressure belt 38 is also mounted in the extension arm 37, which serves primarily to press the newspapers 11 onto the vertical section of the conveyor 15 that is active between the deflection rail 17 and the deflection roller 18. Since this section of the active conveyor strand is of variable length, the pressure belt runs around a length compensation device. As can be seen in FIGS.
  • the band 38 runs around the deflection roller 18 which can be displaced vertically with the frame 24, then around a roller 39 which is fixedly but rotatably mounted in the extension arm 37 and from there around a first deflection roller 40 a second deflecting roller 41, around a third deflecting roller 42 and finally around a larger fourth deflecting roller 43 arranged above the start region of the conveying active run of the conveyor 15 40, 42 rotatably mounted in a roller frame 45 which can be displaced horizontally in the boom 37 against the action of a gas spring 44.
  • the roller frame 45 can be up to the position shown in dashed lines in FIGS. 1 and 1A move and thereby releases as much length of the pressure belt 38 as is necessary to follow the downward movement of the frame 24, while the gas spring 44 ensures a shortening of the active length of the pressure belt 38 during its upward movement.
  • a stack carrier 46 in the form of a turntable is located under the outlet 20 of the conveyor 15. On its underside, the stack carrier 46 is provided with rollers 47 arranged at uniform circumferential intervals and with laterally effective guide rollers 48 which are supported or guided by a guide rail 49 which describes a circular path and is L-shaped in cross section. So far essentially the construction common to the embodiments of FIGS. 1 and 1A.
  • a sprocket 50 is mounted in the middle of the underside of the stack carrier 46, which is coupled via a chain 51 to a stationary drive unit 52, the speed of which - as will be described later - can be varied continuously in a controlled manner and which rotates the stack support 46 in the direction of arrow 53 about the axis 54.
  • the upper side of the stack carrier 46 is flat and serves to receive the stack 55 shown in FIGS. 1 and 1A with its outline in full height, which was produced from the newspapers 11 fed by the conveyor 15.
  • both the platform 32 with the drive units 29, 31 and the boom 37 together with the conveyor 15 and the pressure belt 38 and the frame 24 with the column 33 can be rotated or pivotable.
  • a gear 56 is seated on the column 33 in the area of its lower end, which meshes with the output pinion 57 of an angular gear 58, to which a reversible motor 59, for example a stop motor or a stepper motor, is flanged.
  • the gear ratio between the pinion 57 and the gear 56 is selected such that the pinion 57 is given the intended rotation of the column 33 in one and in the other direction by a given by the limited pivoting angle of the conveyor 15 (see FIG. 2) Angle of rotation less than one revolution.
  • the current rotational position of the column 33 can thus also be clearly derived from the respective rotational position of the pinion 57.
  • the pinion 57 is therefore connected in a rotationally fixed manner to a cam disk 60, the position of which is sensed by a stationary electrical signal transmitter 61, for example a potentiometer.
  • a swing arm 63 which is only indicated schematically and has a freely rotatable wheel 62 at its end, is articulated on the frame 24 and scans the current height of the stack 55.
  • the rocker arm 63 actuates an electrical height transmitter 64, which in turn switches on or stops the drive unit 31 for the height adjustment of the frame 24 in one or the other direction of rotation via a line 65 and a reversing switch 66.
  • a speed sensor 67 e.g. a tachometer generator, which detects the conveying speed of the individual conveyor 12.
  • the rotational speed of the stack carrier 46 is preferably the conveying speed of the individual conveyor 12 adjusted. Therefore, in FIG. 1, the signal from the speed sensor 67 reaches a guide control circuit 69 via a line 68, which in turn controls the drive unit 52 via a control line 70 and determines its speed. With a constant conveying speed of the individual conveyor 12, the speed of the stack carrier 46 is also constant in FIG. 1.
  • the peripheral speed of the stack carrier 46 is considerably greater in the vicinity of its circumference than in the vicinity of its axis of rotation 54. This means that the scale formation deposited by the outlet 20 in the area of the circumference of the stack carrier is loosened (stretched) in the sense that the distance successive fabrics (scale spacing) is enlarged. In the area of the axis of rotation 54, however, the scale formation is compressed, i.e. the distance between the scales is reduced.
  • the drive unit 29 for the conveyor 15 is coupled via a control line 71 to a second guide control circuit 72, which controls the speed of the Drive unit 29 determined.
  • the signal of the position sensor 61 as the command variable is fed via a line 73 to the input of the guide control circuit 72, while the signal of the speed sensor 67 is fed as a disturbance variable to a further input of the circuit 72 via a line 74.
  • the rotational speed of the drive unit 29 is thus dependent both on the instantaneous distance of the outlet 20 from the rotational axis 54 and on the conveying speed of the individual conveyor 12 and in the course of the conveyance on the conveyor 15 the scale distance is adjusted in the desired manner in a controlled manner before the scale flow is deposited on the stack 55 via the outlet 20.
  • the reversible motor 59 which swivels the conveyor 15 back and forth, is controlled in terms of speed and direction of rotation or - if it is a stepper motor - in terms of step sequence and step direction by a special, programmed guide control circuit 75 via a line 76.
  • This guide control circuit is supplied with the signal of the position transmitter 61 as a command variable via a line 77 and the signal of the speed transmitter 67 as a disturbance variable via a line 78.
  • the master control circuit is now programmed (possibly via a separate program generator 80) so that the motor 59 rotates more slowly in both directions of rotation or executes a step sequence the slower the further the outlet 20 is from the axis 54 and vice versa.
  • dashed dashed line 79 in FIG. 2 this leads to the fact that the individual spiral windings of one and the same spiral winding overlap laterally the further the outlet 20 from the axis of rotation 54 is removed and the less the closer the outlet 20 comes to lie to the axis 54. This guarantees that the upper surface of the stack 55 that is being formed remains essentially flat.
  • a friction wheel 150 also engages on the underside of the stack carrier 46 and is rotatably mounted on the free end of an arm 151 anchored to the platform 32.
  • the friction wheel 150 is positively connected to the drive roller 22 via two chains 152.
  • the circumferential speed of the friction wheel 150 is therefore always strictly proportional - or, with appropriate transmission ratios - even the same as the conveying speed of the conveyor 15.
  • the friction wheel 150 drives the stack carrier 46 and the stack 55 formed thereon in the direction of the arrow 53 about the vertical axis of rotation 54. As will be shown, however, the speed at which the stack carrier 46 is driven depends on the current position of the outlet 20 and thus of the friction wheel 150 with respect to the axis of rotation 54.
  • the speed of rotation in FIG Stack carrier 46 variable. This speed is higher, the smaller the distance of the friction wheel 150 from the axis of rotation 54 and vice versa.
  • the current rotational speed of the stack carrier 46 or the stack 55 at the point immediately below the outlet 20 of the conveyor 15 is adapted to the conveying speed of the latter. 1A that the distance between successive newspapers 11, the so-called "scale spacing" in the stack 55 remains constant, regardless of whether the scale formation in the region of the circumference of the stack carrier or in the vicinity of its axis of rotation on the stack 55 is filed.
  • the motor 59 can be controlled by a program generator (not shown in FIG. 1A), which ensures that the column 33 is rotated by an angle per revolution of the stack carrier 46 which corresponds to an arc at the height of the outlet 20, the length of which is approximately the same or a little smaller than the format dimension of the delivered newspapers 11 measured transversely to the conveying direction of the conveyor 15.
  • control circuits 69, 72 and 75 of FIG. 1 are thus omitted.
  • the outline of a spiral of the stack is indicated by the dashed line 79, which in turn corresponds to a turn of the spiral stack 55.
  • the fold (collar) of each newspaper forms (seen in the direction of rotation 53 of the stack) its leading edge, which comes to lie over the trailing edge (flower) of the preceding newspaper.
  • This formation depending on the manner and the means by which the stack 55 is dismantled, may not be the cheapest.
  • 3 and 4 indicate two possibilities of how the outlet 20 can be designed in order to achieve a different formation on the stack 55 which is being formed.
  • a stop 81 is arranged after the guide roller 19 and at a distance from it, and under the guide roller 19 there is a short connecting belt 82 driven in opposite directions, which ends immediately above the stack 55, which now rotates in the direction of arrow 53 ' .
  • the newspapers leaving the deflecting roller 19 first strike the stop 81 with their fold and then fall on the opposing connecting band 82. On this the leading edge of each newspaper is the cut edge or flower and this comes to lie over the fold of the preceding newspaper.
  • a roller 84 driven in the direction of arrow 83 connects to the deflection roller 19.
  • the roller 84 together with a partially looped around this endless pressure belt 85 a by a circular arc of about 180 0 descriptive conveying gap which receives the the pulley 19 leaving imbricated stream and this turns around 0 180 downward.
  • the fold of each newspaper has its leading edge, which, however, does not come to rest above but below the trailing edge of the preceding newspaper.
