Definitions

  • the invention pertains to a supply station for positioning enclosures on an enclosure-collating path of a mail-processing installation.
  • Known supply stations contain in a housing or in a frame part of the installation a magazine housing for inserting a stack of enclosures.
  • the magazine housing has in its lower front region in the enclosure withdrawal direction a cutout through which the lower and, relative to the enclosure withdrawal direction, front part of a stack of enclosures is uncovered.
  • the particular lowermost enclosure is bent downward, provided that it is flexible enough, at its front part in the enclosure withdrawal direction, and then assumes a position in which it is gripped by a gripper of a supply arrangement, for example, the gripper claws of a gripping arm that can be swiveled back and forth, and is then pulled out in an arc-like movement of the gripper under the remaining stack of enclosures and can be placed upon an enclosure compartment of an enclosure collating path of a mail-processing installation.
  • a gripper of a supply arrangement for example, the gripper claws of a gripping arm that can be swiveled back and forth, and is then pulled out in an arc-like movement of the gripper under the remaining stack of enclosures and can be placed upon an enclosure compartment of an enclosure collating path of a mail-processing installation.
  • enclosures with relatively little flexibility are to be processed in the supply station, then such enclosures, e.g., booklets, thin books, catalogs, folders made of fine cardboard, etc., cannot be bent downward by a vacuum sucker arrangement at the lower end of the magazine housing.
  • known supply stations are therefore used in which the base of the magazine housing is inclined in accordance with the direction in which the mouth of the gripper that is ready to withdraw the enclosure opens, and the comparatively inflexible enclosure is pushed forward by means of pushing arrangements or pusher arrangements acting upon the back of the lowermost enclosure in the enclosure withdrawal direction so that the front edge, in the enclosure withdrawal direction, of the particular enclosure can be gripped by the gripper.
  • the problem that is to be solved by the invention is to create a supply station for the positioning of enclosures on a enclosure-collating path of a mail-processing installation, in which comparatively flexible enclosures and, following a changeover with few manual operations, enclosures that possess little or even no flexibility can be processed,
  • Fig. 1 is a schematic, perspective, partially cutaway illustration of a supply station in a first setting for the processing of flexible enclosures.
  • Fig. 2 is a depiction similar to Fig. 1, whereby in Fig. 2 the supply station is shown in a setting for the processing of non-flexible enclosures.
  • Fig. 3 is a schematic, partially sectional side view of another embodiment of a supply station of the type suggested here, whereby two different operating positions are indicated.
  • Fig. 4 is a highly schematized and partially sectional side view of an embodiment of a supply station, of the type shown in Figures 1 and 2, for example, in order to clarify a useful detail.
  • Fig. 1 shows an enclosure-collating path 1 on which enclosure compartments are formed, by means of conveying finger pairs 2 mounted on conveyor belts or conveyor chains, for example, in which enclosures are collated for forming stacks of such enclosures 3, each stack differing from the others.
  • enclosure-collating path 1 is directed past individual supply stations, one of which is designated by 4 in Fig. 1,
  • Supply station 4 comprises a supply station housing or a supply station frame, whereby in Fig. 1 only the supply station housing side wall 5 that is furthest from the observer is shown as part of a supply station housing.
  • a magazine housing 6 Supported between the side walls 5 of the supply station housing is a magazine housing 6 for the insertion of a stack of enclosures 7, each consisting of same and similar enclosures.
  • the magazine housing is provided in a lower region facing the enclosure-collating path 1 with a cutout 8 that is open in the downward and forward directions. It should be mentioned at this point that the magazine housing 6 and the stack of enclosures 7 inserted therein are shown as a cutaway in a vertical plane parallel to the housing side wall 5 in order to make details of the design more discernible.
  • the base 9 of the magazine housing 6 is lengthened in the rearward direction opposite the enclosure withdrawal direction, and bears a drive 10 of a pushing arrangement or pusher arrangement 11, whereby the drive 10 serves to actuate a pusher element 12 with a strip-like form.
  • the function and mode of operation of the pushing arrangement or pusher arrangement 11 will be explained in detail below,
  • a vacuum sucker arrangement 13 Installed underneath the base 9 of the magazine housing 6 is a vacuum sucker arrangement 13 that exhibits a pivot axle or pivot shaft, which is symbolized by a dot-dash line 14 and which is supported or mounted either on the base 9 of the magazine housing 6 or on the side walls 5 of the supply station housing in such a way that by means of a suitable drive, not shown in Figures 1 and 2, a link rod 15 that bears vacuum suckers 16 can be pivoted back and forth around the pivot axle or pivot shaft.
  • the vacuum suckers 16 are affixed on a given link rod 15 at a position such that when the vacuum sucker 16 is exposed to a vacuum and the link rod 15 pivots counterclockwise relative to the position of Fig.
  • the vacuum sucker 16 grips a particular lowermost flexible enclosure of the stack of enclosures 7 near its front region in the enclosure-withdrawal direction and, with the subsequent pivoting of the link rod 15 in the clockwise direction, bends this region of the enclosure downwards into the position shown in Fig. 1.
  • the magazine housing 6 can be pivoted relative to the receiving station housing around a geometric axis 21, which is oriented parallel to the conveying direction of the enclosure-collating path 1 and the pivot axle 19 of the gripper arm 18.
  • the geometric axis 21 runs at a very specific height above the level of the base 9 of the magazine housing 6, as well as at a specific distance opposite the enclosure withdrawal direction behind the front wall of the magazine housing 6.
  • axle pieces which are coaxial to the geometric axis 21 and one of which is indicated by 22, reach from the side walls 5 of the supply station housing to the particular opposite side wall of the magazine housing 6.
  • a securing arrangement 23 which can be formed by a spring-loaded index pin that is placed on the magazine housing side wall and can be moved perpendicular to same, and index recesses in the side wall 5 of the supply station that interact with it.
  • a securing arrangement 23 can be formed by a spring-loaded index pin that is placed on the magazine housing side wall and can be moved perpendicular to same, and index recesses in the side wall 5 of the supply station that interact with it.
  • many kinds of different designs of securing arrangements can also be used here.
  • the drive 10 which presses the pusher element 12 against the rear edge, relative to the withdrawal direction, of the lowermost enclosure of the stack of enclosures 24, and pushes this enclosure into the position indicated by the dot-dash lines at 25.
  • the gripper 17 can grip with its open gripper claws the front edge, relative to the withdrawal direction, of the lowermost enclosure, whereby because of the oblique position of the magazine housing 6 corresponding to the angle ⁇ , this enclosure is aligned toward the opening of the mouth of the gripper claws, and in addition, protrudes sufficiently for gripping by the gripper claws that their upper part does not come into contact against the enclosures of the stack of enclosures 24 that are still in the stack and lying above.
  • the position of the pivoting axis 21 of the magazine housing 6 is accordingly to be selected in such a way that the base 9 of the magazine housing is placed obliquely enough according to the alignment of the opening of the gripper mouth in order to be able to grip a non-bendable lowermost enclosure, and in addition, in such a way that the bottom region of the stack of enclosures 24 is drawn back to an adequate extent relative to the gripper claws in their maximum position,
  • the pushing arrangement or pusher arrangement 11 can be mounted on the base 9 of the magazine housing 6 so it can be moved and fixed in a particular position in order to adjust to different enclosure formats.
  • side wall parts of the magazine housing 6 can be designed to be adjustable to different enclosure formats. Designs in this regard are completely familiar to the person skilled in the art, so a detailed description is unnecessary here.
  • FIG. 3 which shows another embodiment of a supply station of the type suggested here
  • the same reference symbols are used for all parts that correspond to those of the embodiment according to Figures 1 and 2.
  • the design and function of such parts correspond to those of the corresponding parts according to Figures 1 and 2, whereby a detailed description is to that extent unnecessary.
  • a securing arrangement 23 assigned to the magazine housing 6 has been left out of Fig. 3 for the sake of simplifying the representation, but such a securing arrangement with a function corresponding to a securing arrangement 23 according to Figures 1 and 2 is in any event provided for the magazine housing 6 according to Fig. 3.
  • the position of the magazine housing 6 for the processing of a stack of enclosures 7 comprised of flexible, comparatively thin enclosures is shown in continuous lines, while the position of the magazine housing 6 for the processing of less flexible or completely inflexible, thick enclosures of a stack of enclosures 24 is drawn in dot-dash lines.
  • a rotary feeder 27 which bears on its circumference a gripper 28 and is of a design that is, for example, known in the art, and which is installed underneath the magazine housing 6 and the rotational axis 29 of which runs parallel to the above-mentioned geometrical axis 21, the track of which is also designated by 21 in Fig. 3 and which is oriented perpendicular to the conveying direction of an enclosure-collating path 30, which here runs perpendicular to the front edge, relative to the enclosure withdrawal direction, of the enclosures.
  • a drive that is not shown in Fig. 3 serves to put the rotary feeder 27, which forms the supply arrangement here, into rotation in the direction of the arrow R.
  • the pushing arrangement or pusher arrangement 11 then pushes the lowermost, less flexible or completely inflexible enclosure of the stack of enclosures 24 forward in the withdrawal direction directly into the mouth opening of the gripper 28, so that when the movable claw of the gripper 28 closes, it can be gripped, withdrawn and inserted into an enclosure compartment of the enclosure-collating path 30,
  • the geometric axis 21 can be a virtual pivot axis that is realized in such a way that the guiding and mounting arrangement on the inside of the side walls 5 of the supply station housing or on the outside of the side walls of the magazine housing 6 includes arcuate guides 31 and guide rollers 32 which interact with them and which are accordingly provided on the outside of the magazine housing 6 or on the inside of the side walls 5 of the supply station housing respectively, whereby the center points of curvature of the arcuate guides 31 lie on the mentioned geometric axis 21.
  • the track of the geometric axis is again designated by 21 in Fig. 4 and is shown there,
  • FIG. 4 While the enclosure-collating path 1 is shown schematically cut away in Fig. 4, it is understood that the design of the guiding and mounting arrangement for the magazine housing that was just explained above can also be provided for the embodiment according to Fig. 3 with a rotary feeder as the supply arrangement. It should also be noted with regard to the representation of Fig, 4 that a supply arrangement with a gripper provided at the end of a gripper arm of the type shown in the representation of Figures 1 and 2 has been left out here for the sake of simplifying the representations.
