Definitions

  • the invention relates to the equipment for processing printed and folded polygraphic products of the newspaper type and relates in particular to grippers for the piece-wise removal of these products.
  • grippers are used in conveyor systems for the transportation of newspaper or book and magazine printed products for the piece-by-piece removal of these products, which either represent a forceps gripper brought out by the Swedish company "WAMAC” or a clamping tongue gripper according to DA, A, 25 19 561.
  • This known gripper contains an immovable clamping tongue and a movable clamping tongue attached to a drive shaft.
  • the movable and the immovable clamping tongue are arranged at an angle of 90 ° to one another above the scale stream before the removal of a copy of the newspaper, the movable clamping tongue being rigidly attached to the shaft and lying in a plane which is parallel to the arrangement plane of the immovable Clamping tongue runs.
  • the shaft is lowered until it touches the scale in front of the newspaper to be gripped, the movable clamping tongue is pivoted through 90 ° and guided under the newspaper, and then the shaft, while the movable clamping tongue with the immovable clamping tongue in the same vertical plane is raised to the starting position, so that the newspaper is clamped between the clamping tongues.
  • the movable clamping tongue is pivoted through 90 ° and returned to the starting position. This kinematics is achieved with the help of a series of springs, cams and locks.
  • the known gripper ensures that the newspapers are released piece by piece from the stream of shingles, but is structurally difficult because its devices for guiding the movable and the immovable clamping tongue into the same vertical plane have a complicated kinematics, and are labor-intensive to produce because the union complicated parts in a plant require special equipment and technology for their manufacture.
  • the invention has for its object to develop a gripper for the batch removal of folded printed products, in which the movable clamping tongue and its mounting and fixing are designed so that the gripper should be simple in terms of construction and manufacture.
  • the movable clamping tongue is designed in the form of a two-armed lever pivoted on a shaft in the plane running through the plane of the immovable clamping tongue, one arm of which for driving under the copy of the printed products to be detached from the shingled stream Lowering of the shaft is determined and its second arm cooperates with a lock attached to the shaft to hold this clamping tongue under the detached copy of the printed products, a limiter of the removal of the movable clamping tongue from the immovable being arranged on the shaft.
  • the movable clamping tongue for return to the swing limiter is cushioned when it is released.
  • the grippers 1 according to the invention are attached at certain intervals to the traction element of a spatially guided conveyor 2 which moves synchronously with a conveyor track 3 carrying newspapers 4 deposited in a scale-like manner.
  • Each gripper 1 contains an immovable clamping tongue 5 (FIG. 2) and a movable clamping tongue 6, which is designed in the form of a two-armed lever articulated on a shaft 7.
  • the axis 8 of the joint runs through the fork 9 of the shaft 7 and carries a spring 10.
  • One of the ends of the spring 10 cooperates with the cheek of the fork 9 and the other with the movable clamping tongue 6 and thus ensures that it is pressed against a pivot limiter 11 which is on the cheeks the fork 9 is fastened and carries a roller 12 located behind the fork 9.
  • a spring-loaded lock 13 is attached, in which one of the ends 14 is inserted into the fork as far as it will go into the swiveling zone of the movable clamping tongue 6 and the other end 15 interacts with stops (not shown in FIG. 2), which are arranged along the lines of the conveyor 2 at the newspaper drop points.
  • the immovable 5 and the movable clamping tongue 6 are arranged in the same vertical plane.
  • the arm 16 of the movable clamping tongue 6 lies in the starting position at an angle to the axis of the shaft 7 and interacts with the newspapers when the shaft 7, which moves in a bushing 17 fastened to the conveyor (FIG. 3), in cooperation with the Roll 12 goes down with a template 18, while the arm 19 of the movable clamping tongue 6 cooperates with the end 14 of the lock 13.
  • the return of the shaft 7 to the starting position takes place under the action of the spring 20.
  • the gripper according to the invention works as follows.
  • the shaft 7 begins to lower and bring the arm 16 of the movable clamping tongue 6 closer to the newspapers which accumulate in the shingled stream. Then, in the course of the lowering of the shaft 7, the end of the arm 16 abuts the newspaper 4, which precedes the one to be detached from the stream of shingles by the gripper 1 in question. With the further lowering of the shaft 7, the arm 16 of the movable clamping tongue 6 begins to deflect down to the side of the immovable clamping tongue 5 and to travel under the newspaper to be detached until the arm 19 of this clamping tongue is snapped in by the end 14 of the arrester 13. Then begins to move the roller 12 upwards on the template 18, the shaft will go up under the action of the spring 20 and lift the movable clamping tongue 6 held by the arrester 13 and the edge of the newspaper 4 lying thereon.
  • the design of the movable gripping tongue in the form of a two-armed lever, which is pivoted on the shaft in the plane of arrangement of the immovable clamping tongue for driving one end under the newspaper to be detached and holding the other end after completion of this process, enables the construction of the gripper and to simplify its manufacturing technology.
  • the present invention can be used in spatially guided conveyors for the transportation of newspaper or book and magazine printed products.

Abstract

La pince comporte des mâchoires fixe (5) et mobile (6). La mâchoire mobile (6) est composée d'un levier à deux bras montés de manière articulée sur une tige (7) avec la possibilité d'effectuer des rotations dans un plan traversant le plan de la mâchoire fixe. L'un des bras (16) dudit levier est conçu pour être placé sous le produit imprimé à séparer de la cascade pendant l'abaissement de la tige (7), alors que l'autre bras (19) coopère avec un élément de fixation (13) monté sur la tige (7) et conçu pour retenir ladite mâchoire sous le produit séparé.
