Definitions

  • the invention relates to an arrangement for pre-separating print carriers, in particular letters stacked upright one after the other as a stack of letters, which are fed laterally away from the stack of letters to a separating device and then to a successor device, such as a franking machine.
  • the letters are usually either one above the other or one behind the other and can have different thicknesses and the permissible formats in an irregular sequence.
  • the processing of letters stored in this way is referred to as mixed mail operation.
  • the forces counteracting the transport are difficult to manage in such a system, since in particular the force applied to the stack of letters must not be greater than the force applied by the means of transport or guides of the successor devices to the individual letter. In this way, when the forces are distributed differently, letters are no longer fed, but pressed and jammed in the facility.
  • a device for separating mail pieces, which are stored in an upright orientation as a stack of letters in a receiving area, is described, for example, in US Pat. No. 4,615,519.
  • the stack of letters is pressed by means of spring force against a pull-off device by a thrust element guided on a carrier.
  • the take-off device consists of a drive roller made of rubber disks spaced one above the other on an axis. A part of the roller body protrudes over a guide plate opposite the receiving area and lies flat against the letter side surface of the foremost letter of a stack.
  • the guide plate engages tooth-like in the gaps between the rubber washers Due to the spring force, there is an approximately constant force between the stack of letters and the drive roller.
  • force is first applied to the stack of letters by means of the first pair of cushions, in order to separate the foremost letter from the stack and to bring it forward in such a way that the rear edge of the letter in the transport direction comes in the area of the stop plate.
  • the second pair of cushions in turn prefers a letter and at the same time the letter lying on the stop plate becomes gripped on the edge of the letter by the bevelled side surfaces of the upholstery and pushed into the separating device.
  • the disadvantage of this solution is that the application of force over the edge of the letter can lead to puffing, crumpling, breaking out or jamming of the letter in subsequent devices, and thus automatic operation is not guaranteed. There is also a risk of rapid wear on the upholstery.
  • the purpose of the invention is to increase functional reliability.
  • the invention has for its object to provide an arrangement with which the stack of letters is loosened so that the letters can be easily and safely removed from the stack.
  • a maximum stroke results from the distance of the tangent of adjacent projections to the envelope level of the drive roller. It is advisable to distribute the projections evenly over the circumference of the drive roller. Other settings, such as thickness and format adjustment, as well as a pre-sorting of the letters are not necessary.
  • a further drive roller can be arranged in the guide plate in order to achieve better agitation in the case of large-format letters, in order to better overcome the acting friction and adhesion forces.
  • a synchronous mode of operation of the drive rollers must be set so that the projections of the respective rollers simultaneously transfer impacts to the stack of letters.
  • a stable preferred position of the stack of letters is achieved by the inclination of the guide plate.
  • the axis of the drive roller is parallel to the guide plate.
  • FIG. 1 shows a perspective view of an arrangement according to the invention.
  • a stack of letters is placed upright in the filling area delimited by a stop plate 5 between the pressure bracket 3 and the guide plate 2.
  • the pressure bracket 3 protrudes from the deck and is arranged parallel to the guide plate 2 opposite a drive roller 1.
  • the pressure bracket 3 is guided in a spring-loaded manner and can be moved in the directions indicated by the arrows.
  • the pressure bracket 3 presses the letter stack constantly in the direction of the guide plate 2 against the drive roller 1. This increases the normal force between the drive roller 1 and the foremost letter, so that the stack of letters can slide and is always against the drive roller 1.
  • the influence of the pressure bracket 3 depends on the weight of the stack of letters.
  • the influence of the pressure bracket 3 on the normal force is less, if there are many thin letters on the drive roller 1, the influence is greater.
  • the pressure force is generated by a spring, which must be set so that the stack of letters can slide without building up excessive frictional forces between the guide plate 1 and the stack of letters. It is advantageous to design the surface of the pressure bracket 3 facing the drive roller 1 such that this surface is adapted to the roller enveloping circle in order to ensure that a last thin letter is carried along.
  • the drive roller 1 protrudes through an opening 21 in the guide plate 2 and is provided with at least one projection 11 located on the outer contour of the drive roller, see also FIG. 4.
  • the drive roller 1 and Pressure bracket 2 cooperate in such a way that a sufficient force is impulsively applied to an intermediate stack of letters by the protruding outer contour to overcome the frictional and adhesive forces that counteract the transport.
  • the drive roller 1 shakes the stack of letters and feeds letters to the separating device 6, which feeds the letters individually to a downstream device, for example a franking machine.
  • the deck on which the letters are placed falls in the direction of the guide plate 2, the guide plate 2 also being inclined obliquely backwards, preferably arranged at an angle of 18 ° from the plumb line. This enables the stack of letters to be held in a stable position.
  • An advantageous embodiment relates to the pre-separation of large-format letters weighing up to about 1000 g with two spaced drive rollers 1.
  • the distance between the openings 21 in the guide plate 2, through which the drive rollers 1 protrude, should be chosen so that both drive rollers 1, before the letter is pre-isolated, capture the letter area of all permitted large-format letters.
  • the active surfaces of the synchronously rotating drive rollers 1 are always to be arranged in a contour-identical and contour-parallel manner in order to compensate for the larger frictional forces occurring in large-format letters between the guide plate 2 and the stack of letters by means of parallel force introduction. Since the principle of action is identical for both drive rollers, even a large-format letter lifts almost completely from the guide plate 2 and the stack of letters is shaken sufficiently to achieve easy separation and safe transport to the separating device 6.
  • FIG. 2 shows the top view of the arrangement according to the invention with the stack of letters inserted.
  • the stack of letters 4 is formed from a number of unsorted, mixed mail pieces, which are different in relation to letter formats, letter thickness and weight.
  • the stop plate 5 limits the filling area for the stack of letters 4 in the pull-off direction and forms a stop edge for the approximate lateral alignment of the letters.
  • the guide plate 2 supports the letter stack 4 to the front and holds the letter stack 4 in the stable preferred position, supported by the spring-loaded pressure bracket 3, which presses the letter stack 4 against the guide plate 2.
  • the letters are pre-separated by means of the drive rollers 1 and guided to a separating device 6 along a path which is not designated.
  • the drive roller 1 consists of a base body 12 with an outer contour with at least one projection 11 extending over the length of the roller.
  • the projection 11 extends beyond the base body 12 and is arranged parallel to the axis of rotation 13.
  • the projections 11 project wholly or partially from the openings 21 in the guide plate 1, shown in FIG. 1.
  • the projections transfer 11 impacts to the stack of letters and shake it up.
  • at least the foremost letter is grasped by the projections 11 rotating around the axis of rotation 13 and moved laterally to the feed path of the singling.
  • the force to be applied to the stack of letters can be adjusted via the stroke that the drive roller can exert in the direction of the stack of letters.
  • the maximum stroke corresponds to the distance h between the tangent T via two adjacent projections 11 to the envelope plane H of the drive roller.
  • materials or surfaces for the projections 11 are preferably to be selected that allow the letter to be carried along optimally.
  • a polyurethane material is particularly suitable. For example, a slip effect that does not guarantee safe transport can occur when the slip coefficient is too low. If the coefficient of friction is chosen too large, stacking partners are transported safely, but with such great force that the letters can get stuck in the separating device. It is advantageous to arrange protrusions 11 interchangeably.
  • FIG. 4 shows a drive roller according to the invention with recesses for cylindrical shaped parts.
  • Cylindrical segment-shaped recesses 121 larger than a half cylinder, are formed in the cylindrical base body 13 of the drive roller 1.
  • Cylindrical shaped parts 111 are inserted into these recesses in a non-positive and positive manner.
  • the molded parts 111 are preferably to be arranged distributed over the circumference of the base body 13 at the same distance.
  • the geometrical shape of the molded parts 111 is not limited to these versions; various geometrical structures can be used, which should advantageously not have a sharp contour on the friction surfaces.
  • Fig. 5 shows a further embodiment of the attachment of projections on the outer contour of the drive roller. Uniformly spaced and axially parallel shaped cylindrical segment-shaped parts 112 are fastened on the base body 12.
