Definitions

  • the invention relates to a stacking device for letters and similar flat, flexible conveyed goods according to the preamble of claim 1.
  • the items are transported individually on a conveyor line for the purpose of automatic reading of the destination and later sorting and assigned and stacked over a specialist line with switches corresponding to the postcode areas to a large number of stacking compartments.
  • the spindle wheel drive per stacking compartment is very complex and costly.
  • the complex spindle wheel solution was therefore attempted to be avoided by stacking the items in the stacking compartments and using gravity to take advantage of the preceding item due to its weight and bending rigidity lowers the fact that the following program pushes itself over the preceding program. Difficulties arise here, however, when the items, such as airmail letters, are very soft and the sorting performance should not fall below a predetermined value.
  • the invention has for its object to avoid the difficulties mentioned in a stacking device of the type mentioned in the preamble of claim 1.
  • the stacking is to be made operationally reliable, so that, even in the case of mail items with low bending stiffness, the stacking speed of mail items destined for the same stacking compartment is achieved with the highest possible stacking speed.
  • the additional guide device attached to the inlet bracket can consist entirely or partially of resilient material.
  • the additional guide device can be biased by means of a spiral spring or can perform its function in a very simple manner using gravity.
  • Fig. 1 shows the side view of two sections of a fine letter distribution system, which consists of a large number of stacked compartments 10 arranged next to each other and small capacity.
  • the stacking compartments have an inclination above the horizontal by the angle ⁇ , around the items such as Cards and letters - in the following abbreviated "letters" - to give a stable rest position on the stop page 6.
  • the letters are conveyed by means of conveyor belts with their surface perpendicular to the image plane coming from the right in the direction of the arrow in switches to the stacking compartments assigned to their postcodes.
  • a single stacking compartment 10 is shown in FIG.
  • the letter assigned to the stacking compartment is fed to the stacking compartment by a so-called shroud system, consisting of a transport belt 3, a transport roller 4 assigned to the stacking compartment 10, and with a corresponding rack ten switch 5 forced to leave the conveyor belt 3.
  • a so-called shroud system consisting of a transport belt 3, a transport roller 4 assigned to the stacking compartment 10, and with a corresponding rack ten switch 5 forced to leave the conveyor belt 3.
  • the letter 11 then runs into the stacking compartment, slides along the ceiling of the stacking compartment and the lower edge of an inlet bracket 1, normally over the rear edge of the preceding letter 9 onto the letters 8 already stacked due to the inclination of the stacking base 7 and thus the Stacking compartment 10 by the angle ⁇ to the horizontal ensures that the letters slide properly up to the stop wall 6.
  • the inlet bracket 1 presses with its flattened end 15 at a distance from the stop wall 6 on the stacked letters, so that the last letter received is caused due to its bending stiffness to lower onto the already stacked letters.
  • the lowering of the trailing edge of the letter has an undesirable effect, the air cushion to be displaced and the adhesion of the letters to the inlet bracket 1 as a result of electrostatic charges.
  • the inlet bracket 1 In order to be able to properly stack even large-area mail items with low bending stiffness and low weight, such as air mail items, the inlet bracket 1 has an angle-iron-shaped cross section, the leg ends of which point in the direction of the staple space. On the one hand, this prevents the letters from sticking to the inlet bracket. Furthermore, an additional guide device 2 is provided in the space formed by the legs of the inlet bracket 1 with an angle iron-shaped cross section, which is fastened in the inlet bracket 1 in the area of its bearing 13, has a certain angle ⁇ to the inlet bracket 1 in the rest position and in the space of the angle iron Cross section of the inlet bracket 1 is pivotable.
  • the additional tension of the letters is sufficient to not only let the respective front edge of the letter slide along the stacking compartment ceiling, but also after the additional guide device 2 has been pressed in on the lower edge of the Let inlet bracket 1 slide along.
  • the force of the additional guide device 2 acts on the rear part of the letter and lowers it to such an extent that the front edge of the subsequent letter, when the additional guide device 2 is again pressed into the inlet bracket 1, properly over the preceding shipment arrives.
  • the desired deflecting force of the additional guide device 2 can be realized in that when the additional guide device 2 is fastened on one side near the inlet bracket 13, the additional guide device 2 consists entirely or partially of resilient material and without the external force the win shown in FIG. 2 kel ⁇ between inlet bracket 1 and additional guide device 2 takes.
  • FIG. 3 Another simple embodiment is shown enlarged in FIG. 3. It provides that the additional guide device 2 and the inlet bracket 1 have the same axes of rotation 13.
  • the additional guide device 2 and the inlet bracket 1 are two-sided levers, each with a short lever arm 22 or 14.
  • the short lever arm 22 of the additional guide device 2 is now shaped such that when the angle ⁇ between the additional guide device 2 and inlet bracket 1 is taken, the short lever arm 22 the additional guide device 2 rests on the inlet bracket and thereby determines the angle ⁇ .
  • a spiral spring deflecting the additional guide device 2 can be provided on the bearing 13.
  • Another embodiment of the additional guide device 2 does not require an additional spiral spring and uses gravity as the deflection force.
  • FIG. 4 shows the section AA of the stacking compartment, as can be seen from FIG. 2.
  • the same parts are provided with the same reference numerals, so that no further explanation is necessary.
  • the inclined rear wall which carries the stacking compartment 10 and, by its inclination, provides 16 for the second defined position of the stacked letters 8.
  • the effect of the additional guide device 2 is supported by the design of the long end 15 of the inlet bracket 1. It is advantageously flattened to form a sliding surface, the sliding surface being directed almost parallel to the surface of the stacked letters. A slight curvature of the sliding surface in the direction of the longitudinal axis of the inlet bracket advantageously brings about a uniform frictional force on further incoming letters, regardless of the height of the stacked letters.
