  • movable second gripper part can also be exerted pressure on the object. Shifts of the held objects during and after the opening of the gripper are thus avoided.
  • the grippers according to the invention can be realized, for example, on the basis of conventional grippers with substantially equal gripper jaws.

  • the conveyor track is preferably curved in the transfer area. In the view transverse to the conveying direction of the second gripper part is thus oriented approximately tangentially to a circular path, which has the same center as the conveyor track, but a larger radius.
  • Controllable second gripper parts can be realized mechanically simple: Since the gripper jaws are normally spaced from their conveying member, a change in the Barmkrümmung the conveyor path to the fact that change the distances between two arbitrary reference points on adjacent grippers. Such a change in distance also occurs, for example, between a reference point on a gripper and the conveying member, e.g. a subsequent chain link, on.

  • the second gripper part can roll due to its shape on the object to be dispensed or on the conveying surface respectively to roll off.
  • the second gripper part can therefore interact flatly and not only at points or along a line with the object.
  • the second gripper part has an elasticity which is greater than that of the first gripper part.

  • the main difference lies in a flexible extension 90, which is connected to the pivotable second gripper part 14 of the extended first gripper jaw 11.
  • the extension 90 is a thin, rectangular in plan view element, which is flexible by suitable choice of the form or the material.
  • the extension 90 consists for example of spring steel.
  • an extension 90 is located on the outer lateral edge of that edge of the second gripper part 14, which faces the hinge 15.
  • the extension 90 points to the gripper mouth or stop 16 and aligned with the second gripper part
  • the extension 90 rests on the first gripper part 13.
  • the top 91 of the extension 90 does not protrude from the support surface, but aligned with this, the second gripper part 13 has a region 13c of reduced thickness, in which its top is slightly curved.
  • Fig. 7 shows the state in which first and second gripper parts 13, 14 are pivoted relative to each other from the straight position (Fig. 6). The extension 90 is now lifted from the first gripper part 13.
  • the second gripper part 13 in contrast to FIG. 1, is not rectangular but designed to be laterally bulging towards the outer end. 2009/000231
  • the function of the extensions 90 will be explained with reference to FIGS. 9a and b.
  • the articles 100 are deformed when they are transferred to the removal device 50, since their leading edge 102 is still held between the first gripper part 13 and the second gripper jaw 12 and bent upwards while the trailing part of the article 100 already rests on the horizontal conveying surface 51 and is pressed by the second gripper part 14 against the conveying surface 51.
  • the lifted front edge 102 provides a surface for attacking the airstream. It can therefore happen that the object 100 is not filed clean, but shifts when depositing. This is undesirable.
  • the projections 90 counteract the lifting of the conveying surface 51 by also pressing the leading part of the article after opening the gripper 10 on the conveying surface 51. As a result, a gap between the article 100 and the conveying surface 51 is closed immediately after opening the gripper 10. In the closed state of the gripper 10 of the extension 90 is bent because of its flexibility as the gripped object 100. In the open state he takes his rest position shown in Fig. 6 and 7 a.

Abstract

L'invention concerne un dispositif servant à transporter et délivrer des objets plats (100), de préférence flexibles, en particulier des produits imprimés, et un procédé de fonctionnement correspondant. Le dispositif comprend une pluralité de pinces (10) qui peuvent être déplacées dans un sens de transport (F) le long d'une bande transporteuse (U) fermée définie par un organe de transport (20). Les pinces (10) comprennent une première et une deuxième mâchoire de pince (11, 12) qui peuvent prendre une position de serrage et une position d'ouverture l'une par rapport à l'autre. La première mâchoire de pince (11) est allongée par rapport à la deuxième mâchoire de pince (12) et comprend une première partie de pince (13) qui coopère dans la position de serrage avec la deuxième mâchoire de pince (12) et une deuxième partie de pince (14) qui fait saillie dans la position de serrage au-dessus de la deuxième mâchoire de pince (12). L'orientation des première et deuxième parties de pince (13, 14) de la première mâchoire de pince (11) l'une par rapport à l'autre est variable et peut être réglée par un dispositif de commande (40). De ce fait, la deuxième partie de pince (14) peut coopérer, par exemple, avec un support de transport (51) d'un dispositif de transport (50) pour stabiliser les objets (10) lors de la délivrance sur le dispositif de transport et pour délivrer ainsi les objets de manière contrôlée.
