Definitions

  • the invention relates to a device for reducing the impact speed of printed products in the base of a delivery paddle wheel of printing machines according to the preamble of claim 1.
  • cam disks are arranged on double-lever-like arms rotatably mounted about the bucket wheel axis, in each case between the bucket wheel disks.
  • rings are attached to a rotatable shaft.
  • This shaft is mounted in a frame enclosing the extension impeller which, together with the double-lever arms, can be adjusted about the axis of the extension impeller by means of an adjusting device.
  • This adjustment is used to ensure that when converting production to a product with a different format, which has an impact on the delivery paddle wheel in the form of different product lengths, the product is detected and braked at the trailing end and before it hits the blade base.
  • it is necessary to additionally adjust the cam disks in the new position. This additional adjustment of the cam discs makes adjustment in the course of the machine and automation of the adjustment more difficult.
  • the object of the invention is to provide a device for reducing the impact speed of printed products in the base of a delivery paddle wheel, which allows easy adjustment even with the machine running to different format lengths of the printed products, and in which the position of the cam disks with respect to the printed products for each Position is optimal.
  • the position of the leading edge with respect to the delivery paddle wheel is always the same, regardless of the length of the printed product. It is achieved with the device according to the invention that when the position of the cam disks is adjusted, which must be aligned with the trailing end of the printed product, which depends on the length of the printed product, the position of the cams with respect to the printed products always remains optimal. Starting from a set position of the cam disks, in which one of the cams is directed against the axis of the extension bucket wheel, when the position of the cam disks is adjusted when the machine is at a standstill, this cam is always directed against the axis of the extension bucket wheel. This is achieved by the practical correspondence of the ratios of the effective length of the lever to the effective length of the swivel lever and the ratio i (drive elements to camshaft shaft) to i-1.
  • lever lengths and drive ratio exist with a ratio in the order of two. This does not result in an excessively large swivel angle for the levers and the drive elements also have no oversized dimensions.
  • the longitudinal guide for the pivoting lever is advantageously arranged on the connecting straight line between the axis of the extension bucket wheel and the cam disk shaft when the cam disks are in the middle of their adjustment range.
  • the longitudinal guides for the pivot of the pivot lever are also arranged so that the pivot moves in the straight line mentioned. A symmetrical behavior is thus achieved for the setting both for the printed products with the shortest length and for the printed products with the greatest length.
  • a further advantageous embodiment of the device is that the levers arranged on both sides of the extension impeller are extended beyond the extension impeller with respect to the cam disks and are connected to one another by a web. Also connected to this web are the roller levers bearing the roller, which are pivotably mounted on the axle between the disk-shaped blade portions of the extension blade wheel, and their rollers, which, in cooperation with the cam disks, form the printed product brake, their position with respect to the cam disks even when adjusted maintained.
  • the delivery paddle wheel 1 can be rotated about the axis 2 according to FIGS. 1 to 3 and is driven in the direction of the arrow 3.
  • the vanes 4 are attached, which form pockets 5, into which the printed products 6 delivered by the folder are inserted, in order then to be laid out in the form of a scale.
  • the levers 7 are pivotally mounted on both sides of the extension bucket wheel 1 about the axis 2.
  • a shaft 8, on which the cam disks 9 are seated, is rotatably mounted in the levers 7.
  • Each cam disk 9 is equipped with cams 10.
  • the shaft 8 is equipped with a toothed belt wheel 11, which is driven via a toothed belt 12 in the direction of arrow 21.
  • a pivot lever 13 is hinged at one end 14.
  • a pin 16 On this pin 16, a drive element 17, designed as a toothed belt wheel, is rotatably mounted, which the Timing belt 12 drives.
  • the pin 16 is guided by longitudinal guides 18 (FIG. 4), which allow the pin 16 to move back and forth in the radial direction to the delivery paddle wheel 1.
  • the toothed belt wheel 17 is connected via a coupling 19 (FIG. 4) to a drive device 20 fixed to the machine frame.
  • the drive device 20 is coupled to the machine drive in a known manner.
  • the cam disks 9 interact with rollers 22.
  • the rollers 22 are arranged between the disk-shaped blade parts 23 (FIG. 4) and are each set in rotation individually via a drive 24.
  • the printed products 6 arrive in time with the delivery paddle wheel 1 in the pockets 5 formed by the blades 4. The time at which the printed product 6 dips into the pocket 5 always remains the same for the front edge 25 of the printed product 6, regardless of its length .
  • the printed products 6 entering the delivery impeller 1 at high speed are briefly held between the cam disc 9 and the roller 22 by the arriving cam 10 at their trailing end 26, braked, released by the cam 10 and reach the bottom 27 at a reduced speed immediately after being released the pocket 5, where they are braked to the final speed at which the delivery paddle wheel 1 is driven. Since the last speed difference is only small, the printed products 6 reach the bottom 27 of the pocket 5 without being damaged and without rebounding, which then enables a perfect scale delivery.
  • Fig. 1 shows the position of the cam disks 9 for a printed product 6 of medium length.
  • Fig. 2 the position of the cam disks 9 for a printed product 6 with the smallest length is shown, with the same position of the delivery impeller 1 as in Fig. 1.
  • the cam disks 9 with the associated rollers 22 are pivoted into the position shown.
  • the design according to the invention ensures that the cams 10 remain in the optimal position with respect to the trailing end 26 of the short printed product 6.
  • the pin 16 is displaced along the longitudinal guides 18 in the radial direction to the extension impeller 1.
  • the cam disks 9 are rotated back somewhat by the selected dimensions, i.e.
  • the cam 10 shown in engagement always points against the axis 2 of the extension bucket wheel.
  • the axis 2 of the extension bucket wheel 1 is held in the bearing 29.
  • a schematically illustrated drive 30 sets the delivery paddle wheel 1 in rotation.
  • the levers 7 are arranged pivotably about the axis 2 on both sides of the extension bucket wheel 1; only one side is shown in FIG. 4.
  • the shaft 8 is held in the lever 7 by bearings 31.
  • the pivot lever 13 is seated with its one end 14 on a bearing bush 32 and is pivotable. Its other end 15 is provided with the pin 16 which, on the one hand, is guided in the longitudinal guides 18, which are fastened to the side wall 28 with a bracket 33, and on the other hand carries the timing wheel 17, which is freely rotatable.
  • the clutch 19 connects the toothed belt wheel 17 with the machine frame-fixed drive device 20.
  • the coupling 19 can transmit rotary movements of offset shafts synchronously.
  • the levers 7 are extended on the side opposite the shaft 8 beyond the extension paddle wheel 1.
  • a web 34 connects the two levers 7.
  • the roller levers 35 which carry the rollers 22 and are also pivotable about the axis 2, are fastened between the disk-shaped blade portions 23, 23 '.
  • cam disks 9 and rollers 22 form a unit, regardless of the position they occupy.
  • Each of the rollers 22 is driven separately by a drive unit 36, coordinated with the rotation of the cam disks 9.
  • the pivoting of the levers 7 about the axis 2 of the delivery bucket wheel is carried out by known means, not shown, which can be actuated both automatically and by hand.
  • the swiveling can take place while the machine is running or at a standstill.
