Definitions

  • the invention relates to a device for aligning flat Shipments according to the preamble of claim 1.
  • An input device for mail items has become known from US-A-3 598 400, in which a standing stack of items by means of an underfloor belt and Cutting knives, which are driven separately, are fed to a separator.
  • a separator To avoid skewed positions that negatively affect the deduction process influence, there are two resilient sensors shortly before separation, the lower via a switch the drive of the underfloor belt and the upper controls the drive of the cutting knife. If the respective switch is over the sensor is not needed by the frontmost shipment, so it stays associated drive switched on until the foremost shipment with your upper or lower part actuated the respective switch via the sensor. Thereby skewing is avoided.
  • the disadvantage here is the necessity of the separately controlled drive of the underfloor belt and cutting knife.
  • the object of the present invention is therefore a device for quick and safe alignment of flat, to the conveyor belt level a separating device inclined shipments with respect to the State of the art to create less control and drive effort.
  • the object is achieved by the teaching specified in claim 1.
  • the coupling of the switch signals of the two sensors means that independent transport with the associated control of the upper and lower parts of the mail item is no longer necessary, so that only one funding with one drive is sufficient.
  • Further configurations can be found in the subclaims.
  • the configuration according to claim 4 prevents the stack pressure from increasing unintentionally in the case of thick mail items in the rear area and the sensor not being actuated as a result. Only when the support rollers have returned to their normal position and the thick letters are isolated, is the funding switched on again and the sensors can start functioning again. If the inclination of the mail items exceeds the range that can be corrected by the sensors, then according to the lining of the invention according to claim 5, the removal process is stopped via distance sensors and the speed of the conveying means is increased. The transport at the increased speed takes until this great incline has disappeared. By increasing the speed, this process is carried out as quickly as possible.
  • the increase in the speed of the funding are advantageously carried out depending on the inclination of the consignment, d. H. the greater the incline, the greater the speed.
  • Fig. 1 the top pulley 1 and the top trigger 2 is closed detect. Furthermore you can see the upper sensor 3, the tip of which Band level protrudes.
  • the sensor 3 is by means of pivot 5, spring 6 and Stop 7 resiliently mounted and adjusted.
  • the switches for sensors 3 and 4 are not shown in detail. Suspended support rollers 8 can also be seen, their movement to recognize one-sided thick mail items in the form of letters is being used.
  • Fig. 2 shows in section the take-off belt 2 and the suction openings contained therein 9.
  • the mail items 10 lie with their longitudinal edge on a support surface 11 on.
  • the funding consists of a not shown Cutting knife that pushes the stack of items to the point of departure and one moving belt as a support surface 11. Both movements are coupled together.
  • the funding can only come from the moving cutting knife consist.
  • the fixed contact surface 11 must have a low coefficient of friction exhibit.
  • the tips of sensors 3 and 4 protrude from the Conveyor belt level and counteract the stack of items with spring force. After the deduction of programs 10, the sensor 3 u. 4th to the shipment stack and switch on the funding.
  • the consignment stack can be used Trigger belt level inclined to the trigger point.
  • the lower sensor 4 is up to the switching point operated.
  • the upper sensor since the upper sensor has not yet been operated, it is transported the funding continues the stack of items to the point of departure and directs the Stack up. This also switches the upper sensor 3 and the funding is stopped. If the stack is inclined in the opposite direction, the switch first upper sensor 3 and only then the lower one. In this case, too Stack at the trigger point.
  • the switching point of the Sensor 3 u. 4 be tracked.
  • the trigger tapes 2 are scanned. Via an associated spring-loaded lever device on which the Switches with adjustable stops are attached to this requirement solved.
  • the separating device can have different positions in the Have space.
  • the shipments are vertical standing on a long edge to the side, there is also one 3 has proven to be advantageous.
  • this sensor 3 If this sensor 3 is actuated, it takes off after a certain time a on the driving lever 14 and a driving pin 15 of the sensor 4 on the Stop surface 13 with this, so that after a path b the switching point of both Switch is reached and the funding is stopped.
  • the switching points of the two sensors 3 and 4 are in accordance with the respective specific conditions such as B. consignment quality, spatial orientation.
  • the switching point of the upper sensor is present in the example according to FIG. 4 that of the lower sensor, because this has the lowest double withdrawal rates with high throughput.

Abstract

Le dispositif est utilisé pour l'alignement d'articles expédiés plats qui sont inclinés, par rapport au plan d'enlèvement d'un système de séparation individuelle, et qui sont transportés par des moyens convoyeurs se déplaçant vers un point d'enlèvement, tout en étant maintenus en piles, par un bord, au moyen d'une surface d'appui, et alignés sur une surface d'arrêt. Le système de séparation individuelle présente au moins deux bandes d'enlèvement (2), ainsi que des ouvertures d'aspiration agissant, sous l'effet de la friction et de l'air d'aspiration, sur chacun des articles expédiés (10) à enlever. Le dispositif selon l'invention est caractérisé en ce qu'il comporte, entre deux bandes d'enlèvement (2), deux détecteurs (3, 4) chargés par ressort en direction de la pile d'articles expédiés, placés à distance l'un de l'autre et en saillie par rapport à ces bandes, chacun de ces deux détecteurs étant relié à un commutateur connecté au système commandant l'entraînement des convoyeurs, le point de commutation se trouvant directement devant les bandes d'enlèvement (2), et les convoyeurs étant mis hors circuit dès que les commutateurs des deux détecteurs émettent un signal de commutation à la commande d'entraînement des convoyeurs.
