Definitions

  • the invention relates to an apparatus and a method for weighing an article, in particular a flat postal item, during transport.
  • a device with the features of the preamble of claim 1 and a method with the features of the preamble of claim 10 are known from DE 202007016722 Ul.
  • a weighing object is temporarily clamped in a clamping area between two horizontal endless conveyor belts and led away from the rotating conveyor belts via a scale.

  • the damping element comprises two brushes which are pressed from two sides against the object held in the clamping area. Also possible are other types of guide elements between which the article is passed.
  • EP 2040049 Al a letter scale with calming section is described. This calming zone is provided in front of or behind the scale, so that a mail item passes through this calming zone before or after it is weighed. In this calming zone, the mail piece is guided without lateral clamping.

  • Fig. 1 shows the weighing device with a feeding conveyor 8 and a wegshiftden conveyor 9 in plan view.
  • the feeding conveyor 8 comprises two lateral endless conveyor belts 11, 13 which are guided around rollers. The axes of rotation of these rollers are perpendicular to the plane of Fig. 1.

  • the feeding Conveyor forms a U-shaped transport channel.
  • the mail items are not clamped between the two conveyor belts 11, 13, but lean against only one of these conveyor belts. This causes the weight force aligns the mail items on their lower edges and that the mail items are transported with little slippage.
  • the carrying away conveyor 9 is designed as a U-shaped transport channel. It comprises two lateral endless conveyor belts 18, 19 and an underfloor conveyor belt 10.
  • the weighing device 1 is arranged between the feeding conveyor 8 and the conveying away conveyor 9.
  • the weighing device comprises in the exemplary embodiment two elastic endless conveyor belts 15, 16. These are arranged so that between them a clamping area for temporarily grasping a mail piece is formed.
  • endless conveyor belt 16 the counter-conveying element can also be configured in other ways, for. B. as a role or as a sliding plane, d. H. as an immovable component with a smooth surface.
  • the mail items When passing through the weighing device 1, the mail items are temporarily clamped between two elastic endless conveyor belts 15, 16. Once a mail item has reached the end of the feeding conveyor 8, it is caught by the two endless conveyor belts 15, 16 and is temporarily located between these conveyor belts. These conveyor belts rotate at the same speed and have a rough surface. The mail items are transported with little slippage.
  • Each of the two endless conveyor belts 15, 16 is guided around several rollers.

  • the remaining rollers around which the endless conveyor belts 15, 16 are guided are non-driven rollers.
  • the endless conveyor belts 15, 16 are elastic and tightly guided around the rollers.
  • FIG. 1 by way of example, a thick postal item 5 and a thin postal item 7 are shown.
  • the thin mail item 7 is located just above a scale 17 of the weighing device 1.
  • the thick mail item 5 has already been weighed and is on the way to the conveying conveyor 9 leading away. Both mail items 5, 7 are captured by the two conveyor belts 15, 16.
  • the scale 17 is designed to weigh moving mailpieces.
  • the two conveyor belts 15, 16 are therefore not stopped as soon as a mail item is above the scale 17, but continue to move.
  • the mail item to be weighed is not even slowed down.
  • the weighing device 1 further comprises a damping element 6 which has a curved surface.
  • the endless conveyor belt 15 lies flat against this curved surface of the damping element 6.
  • the damping element 6 preferably has a smooth surface, so that only a slight friction occurs between the conveyor belt 15 or an adjacent mail item and the curved surface. Also, the conveyor belt 16 is flat on this curved
  • the damping element 6 is preferably formed as a solid body. This is connected via a mechanical coupling with that base on which the rollers are mounted, around which the endless conveyor belts 11, 13, 15, 16, 18, 19 are guided around.
  • the mechanical coupling is configured to absorb vibration energy that exerts a mail item on the damping element.
  • Fig. 2 shows the weighing device of Fig. 1 in a side view in the plane B - B.
  • the conveyor belt 15 is omitted. Shown are three endless conveyor belts 13, 16, 19 and a plurality of rollers around which these conveyor belts are guided. The curvature of the Damping element 6 is not shown in the side view. Furthermore, the underfloor conveyor belts 10, 12 are indicated.
  • the thin mail item 7 to be weighed is higher than the endless conveyor belt 16 is wide. This causes a piece of mail to be weighed in a strip on the two endless conveyor belts 15, 16 and in two further strips bears directly on the curved surface.
  • the two endless conveyor belts 15, 16 cause the mail item to be curved.
  • the mail item lies flat against the curved surface of the damping element 6.
  • This configuration has the effect that vibrations which the thin mail item 7 carries out are transmitted directly to the damping element 6 and are damped thereby. As a result, the thin postal item 7 carries out almost no more vibrations when it reaches the scale 17.
  • Fig. 3 shows the weighing device from the front, so a view in the plane A - A of Fig. 2. From the front, the curved damping element 6 appears as a rectangle. Because the movement of the curved mail item 7 is guided past the curved surface, the air resistance causes the item of mail to be pressed in an upper and a lower strip against the curved surface and lies flat against it. Here, the mail piece is slightly curved about its longitudinal axis - as seen in the transport direction. The areal effect causes oscillations of the mail item to be transmitted particularly well to the damping element 6. In a middle strip, the thin mail piece 7 is held by the two endless conveyor belts 15, 16.

Abstract

L'invention concerne un dispositif et un procédé de pesage d'un objet, en particulier d'un envoi postal plat, pendant son transport. Un dispositif de transport constitué d'une bande transporteuse sans fin (15) et d'un élément de transport antagoniste (16) peut saisir temporairement un objet (5, 7) dans une zone de serrage et de le transporter dans une direction de transport (4). La balance (17) peut peser un objet (5, 7), tandis que cet objet (5, 7) est saisi dans la zone de serrage. L'élément d'amortissement (6) est conçu pour amortir des vibrations produites par un objet (5, 7) saisi dans la zone de serrage. L'élément d'amortissement (6) présente une surface courbée dans la direction de transport (4). La bande transporteuse sans fin (15) est guidée autour de la surface courbée, de sorte que ladite bande transporteuse sans fin (15) repose à plat contre la surface courbée dans une zone d'amortissement. De plus, la bande transporteuse sans fin (15) et la bande transporteuse antagoniste (16) sont conçues pour amener un objet (7) saisi dans la zone de serrage devant la surface courbée.
