Definitions

  • the invention relates to a separating device for mail items such as letters, receipts and the like according to the preamble of claim 1.
  • the invention has for its object to improve the state of the art and in particular to create a separating device for letters, receipts, receipts, checks, punch cards, that is mail items of all kinds up to a predetermined size and thickness, which the arriving in any irregular sequence with each other disorderly mail items aligned on a longitudinal or transverse edge.
  • a separating device for letters, receipts, receipts, checks, punch cards that is mail items of all kinds up to a predetermined size and thickness, which the arriving in any irregular sequence with each other disorderly mail items aligned on a longitudinal or transverse edge.
  • the individual consignments should be able to be offered to the downstream units (reading unit, stamping device, coding device, buffer stack and similar units) in a predetermined suitable position at irregular intervals or at an approximately constant distance from one another, ie with a constant gap, for example.
  • deflecting rollers mentioned therein are preferred in practice, but can in principle be realized by different deflecting means and in the sense of claims 17 and 18.
  • the items mentioned in the subclaims are to be understood as flat objects according to the main claim, the length of which is large compared to their thickness.
  • FIG. 1 The basic principle of a separating device used in an automatic letter sorting system is shown in FIG. 1 in top view.
  • the mail items - such as letters or receipts, check cards and the like - are there in any order, preferably essentially in a vertical position in the direction of entry 9 of the separating device fed.
  • the feed can take place, for example, from a pre-distribution channel, in which the mail items are disorganized in an approximately vertical position.
  • the separating device essentially contains a take-off device 4, a guiding unit 3 and a transport device 1.
  • the transport device 1 for example a base belt rotating around two rollers, is preferably arranged in relation to the deflection roller 6 and thus also to the take-off belt 8 of the take-off device 4 in such a way that the transport direction 5 occurs approximately tangentially to the take-off belt 8 when the consignment enters the take-off area, the consignment 10 closest to the take-off belt 8 is in contact with the take-off point P from the take-off belt and is deflected from the infeed direction 9 into the take-off direction 11 within a sheet length predetermined by the change in the direction of transport of the shipment and the radius of the deflecting means 6, which is preferably in the form of a deflecting roller.
  • the mail items assume an approximately vertical position during the entire take-off process, in particular in the take-off area of the take-off device 4.
  • the separating device advantageously contains a guide unit 3 forming a passage gap for the consignment with the take-off device 4.
  • the control unit 3 consists of a part 12, 13 lying essentially to the right and left of the incoming mail items. Furthermore, these parts 12, 13 become a right-hand control unit 12 or left-hand control unit 13 called.
  • the right-hand control unit 12, the control plane 17 of which is perpendicular, begins in the entry area of the mail items, preferably in front of the take-off area at a distance from the take-off area which corresponds at least to the maximum mail item length occurring (see FIG. 2).
  • the right-hand guide unit 12 is preferably equipped with a pressure element 18 which shifts the right-hand guide unit 12 so far parallel to the take-off belt 8, until the guide unit 12 exerts an optimal pressure on the mail items lying in the take-off area and thus also on the take-off belt 8 for pulling off the mail item by the take-off belt 8 (see FIG. 2).
  • the passage gap In order to be able to pull off mailpieces with very different thicknesses, for example 0.1 mm to 10 mm, the passage gap must be designed to be variable at least within this thickness range, in such a way that the pressure element 18 preferably has a constant contact pressure within this range for the pulling off of the mailpieces the shipments and thus caused on the take-off belt 8 via the control unit 12.
  • the left-hand guide unit 13 is designed, for example, in the form of a metal plate, the level of which serves as a well-slidable guide level 15 and is thus arranged in a fixed position in a vertical position towards the trigger device 4, so that the consignments closest to this guide level 15 depend on the takeover point P (this corresponds to the occurring line of contact of the front edge of the shipment with the trigger belt 8 at the beginning of the trigger process) are forced to run tangentially to the trigger belt 8 into the trigger area.
  • Existing mail items that are parallel to the mail items closest to the take-off belt are also forced to run into the take-off area to the take-off belt due to the frictional forces occurring between the mail items.
  • the contact pressure of the guide unit 12 on the right is to be chosen so large that the take-off belt 8 can quickly pull off the next consignment without great slippage.
  • the right-hand guide unit 12 is advantageously equipped with a pressure element 18 which engages the guide unit 12 by means of a tension spring (for example also in the form of a weight) and the guide unit 12 to rotate a vertical axis 16 causes when consignments arrive in the withdrawal area.
  • FIG. 2 shows how specifically a tension spring acts on the guide unit 12 lying on the right, which is rotatably mounted about the axis of rotation 16.
  • the distance of the take-off belt 8 from the guide level 17 of the guiding unit 12 on the right in the take-off area must be selected to be at least as small as the smallest occurring mail item thickness, so that these items also enter the take-off area - by means of the conveyor of the transport device 1 - Experience a sufficient contact pressure for the take-off belt 8 by the guide unit 12 for the take-off process.
  • the passage gap in the trigger area is preferably not significantly larger selected as, for example, 5 times the maximum mailing thickness that occurs.
  • the right-hand control unit 12 rotates correspondingly far from the initial position - this preferably means that the predetermined maximum is exceeded Consignment thickness via the occurring angular rotation of the right-hand control unit 12 is registered by means of a switching unit 19 (for example a microswitch).
  • a switching unit 19 for example a microswitch.
  • the switch - for example, operating state "on" when the maximum mail item thickness is exceeded - switches off the transport device and the units 40 in front of it delivering mail items until the maximum mail item thickness is again undershot.
  • a so-called wiper 14 is preferably arranged in the end area of the take-off device 4, after the guide unit 12 on the right, to avoid double and multiple take-offs parallel to the take-off belt 8, which adjusts itself to the take-off belt by means of a compression spring 114 in accordance with the thickness of the consignment to be removed currently in the wiper area and for an orderly moderate deduction of the consignment lying between the take-off belt and the scraper from the take-off device 4.
  • Other letters lying parallel to it are retained due to the skid shape of the scraper, which is preferably formed in the inlet area.
  • a scraper as described in P 27 04 045 can be used here advantageously.
  • this stripper 14 is shown in FIG. 3A.
  • the scraper 14 presses the letter, for example by means of at least one compression spring 114 (for further suitable forms of training see P 27 04 045), while pulling on the pull-off belts 20 in the region of the deflection roller 7 and thus prevents double and Multiple deductions; at the same time, the runner 141 on the letter side or a guide fence arranged in front of it facilitates entry into the passage gap formed by the pulling belt 20 and wipers 14 up to the detection area of the subsequent conveyor section 66.
  • the springs or weights causing the mailpiece to be pressed onto the take-off belt 8 in connection with the guide unit 12 should be designed to be bounce-free, i.e. damped, so that the optimal contact pressure can be set as quickly as possible.
  • FIG. 3A shows a guiding unit 12 on the right, designed as a bounce-free rocker, which is designed in the form of an inlet wedge 21 with a comb 22 firmly connected at the wedge end.

This ensures that the letters, supported by the funding, can be arranged and aligned, especially in front of the deduction area.
  • the wedge flank 23 should form an acute angle ⁇ 30 ° with the inlet direction 9 (and thus also with the consignment closest to the take-off belt 20), which is chosen so large that there is room for evasive letters for subsequent letters and thus already with one relatively small number of incoming mail, an early blocking of the inlet wedge 21 is avoided. Even consignments that arrive in bulk can better avoid the wedge flank area.
  • the wedge flank 23 should have as little sliding friction as possible so that the mail items attached to it are not turned up by subsequent letters. Teflon or materials with similar sliding properties are preferred.
  • the take-off belt 20 of the take-off device 4 is advantageously arranged in the form of a plurality of horizontally running one above the other at a predetermined distance from one another Trigger bands 20 are formed (see FIG. 3B).
  • the one that broke at the end of the wedge Te comb 22 preferably reaches with its fingers 24 between the gaps of the trigger tapes 20 when there are no letters in the trigger area (see FIG. 3B). This is the rest position.
  • the immersion depth is selected so that the play of the guide unit 21 designed as a rocker is compensated, ie even the thinnest letter to be drawn off, which runs into the pull-off device 4, experiences the optimum contact pressure for pulling off via the pressing device 25, 16 of the guide unit 21.
  • the tension spring 25 transmits, via the inlet wedge 21, which is rotatably mounted about the axis of rotation 16, the predetermined contact pressure to the mail items located in the withdrawal area.

  • FIG. 3A shows the corresponding case in a top view.
  • the curvature of the guide unit 12, 21 on the right must be adapted to the curvature of the take-off belt 20 in the take-off area.

  • guide plate 30 in this case has an approximately pa parallel to the take-off belts 20 with the take-off belt a starting position forming a passage gap dependent on the consignment thickness occurring.
  • the guide plate 30 is rotated out of its starting position when letters exceed the takeover point P (base belt of the transport device 1 conveys letters directly or indirectly through the friction of the letters among themselves to the takeover point P). As the number of incoming letters increases - several letters run into the withdrawal device at the same time - the guide plate 28 and then the comb 30 give way, corresponding to the letter thickness that occurs.
  • the restoring force of the springs 25, 291 generates an approximately constant contact pressure on the letters via the guide plates 28, 30; in the state of equilibrium, this can be achieved as quickly as possible by means of a bounce-free design of the pressure devices, the letter closest to the pull-off belt 20 is pressed onto the pull-off belt 20 with a predetermined approximately constant contact pressure and is pulled off with a small loss of slip.
  • a second pressing device 129 in the form of one equipped with a spring element 130 (tension spring, for example) is advantageously provided Provided rotatably about the axis 131 guide arm 132, which acts on the comb of the guide plate 30 in the linear withdrawal area in front of the conveyor section 66 (see FIG. 5B).

  • the deflecting body 80 is to be fixed and the pulling belt is driven by means of the other deflecting roller.
  • the web to be traversed during the peeling process must be selected according to the types of items to be separated (in terms of thickness, elasticity, etc.).
