Definitions

  • the present invention relates to a conveyor chain, in particular a gripper chain, with at least one gripper tappet, at least one link plate receiving the gripper tappet and a spring means acting between the link plate and the gripping tappet, wherein the gripping tappet has a guide pin and a gripping head.
  • a widely used conveyor chain for transporting film webs is known from DE 30 25 967 C2, in which the film webs are gripped by means of the gripper tappet and moved further by means of the chain and optionally tensioned.
  • conveyor chains are also used, for example, in soldering systems and in the production of printed circuit boards.
  • This conveyor chain consists essentially of a commercial roller chain, in which an outer flap is replaced by a so-called strap (U-shaped) with outwardly facing legs. Both the upper and the lower U-leg each have a slot through which extends the hook-shaped gripping tappet.
  • helical compression spring is arranged, which surrounds the gripper plunger.
  • the upper end of the helical compression spring is supported on the underside of the upper U-leg.
  • the lower end of the helical compression spring is supported on the gripper tappet, whereby the gripper tappet is always pressed into its closed position (gripping position).
  • the lower end of the gripper rams over and can be pushed by means of a cam surface or actuation ramp upwards, so that the gripper tappet opens and the product to be conveyed can be inserted into the open gripper.
  • This type of gripper chains has been well proven in use, however, the cost of producing the individual matched components is high. In particular, the hook-shaped gripper tappet can only be produced in a multi-stage stamping and bending process. Also, the assembly for the production of the conveyor chains is relatively expensive.
  • DE 30 22 075 C3 shows a gripper tappet, which is constructed rotationally symmetrical and is guided only in an opening of an L-shaped bracket.
  • the gripping tappet consists of a substantially cylindrical pin which is provided with a mushroom-shaped head, wherein the film webs between the edge of the mushroom-shaped head and the top of the L-leg is fixed.
  • the mushroom-shaped head is riveted on the bolt.
  • the bolt is provided with a collar bushing, on which a helical compression spring is arranged.
  • the one-piece gripper tappet used in this generic conveyor chain is also constructed rotationally symmetrical, but is performed in the upper and lower legs of a U-shaped bracket plate.
  • the one-piece rotationally symmetrical gripper tappet has, in addition to the mushroom-shaped head with a circumferential gripping edge in the ram shank on a circumferential groove into which a one-sided slotted cup-shaped disc is inserted, against which the lower end of the helical compression spring is supported.
  • the peripheral around the head gripping edge cooperates with a circular groove in the top of the upper strap strap, so that the gripping plunger can rotate in its recording and still always engages in the groove.
  • the film or the gripping material is detected only by the front part of the gripping head, while most of the gripping blade remains ineffective. Due to the complexity of the shape of the gripper plunger and the rotationally symmetrical structure of this is usually made as a costly rotary part.
  • the known from the prior art conveyor chains are used successfully for many years, for example in the packaging industry when transporting film webs.
  • the gripping elements of the conveyor chains for the most part consist of cost-intensive special parts which, due to their shape and the necessary precision, must be manufactured partly in successive work steps.
  • the opening gap between the gripping element and the gripping surface on the upper side of the strap is limited in a U-shaped design by the distance between the U-legs and the space requirement by the helical compression springs.
  • a further disadvantage in particular in the case of stiff film webs or only short insertion sections of the film, is the covering of the support region for the film by the opened gripper element. Therefore, there is also a need for suitable improvements of existing disadvantages as well as generally a reduction in manufacturing costs in the case of conveyor chains which have hitherto proven themselves in operation.
  • the gripping head is hinged about a pivot bearing hinged to the link plate, in particular on the longitudinal side of the link plate, and the guide pin and the gripping head in a movable bearing relative to each other are slidably connected together.
  • the hinged arrangement of the gripping head on the link plate allows for an unchanged by means of a cam surface or actuation ramp generated stroke of the guide pin a significantly enlarged opening gap for insertion of the Greifguts.
  • the guide pin is usually taken up by two openings in the laterally extending legs of the link plate and guided linearly.
  • the sliding movement of the gripping head in the sliding bearing or movable bearing allows the necessary balance between the linear movement of the guide pin and the pivoting movement of the gripping head.
  • the relative movement of the gripping head relative to the guide pin prevents wear in the connection between the guide pin and the gripping head and in the first place allows the combination of the linear movement of the guide pin with the folding or pivoting movement of the gripping head.
  • An expedient embodiment provides that the pivot bearing between link plate and gripping head is fixedly arranged on the link plate and at a distance from the floating bearing between the gripper head and guide pin.
  • the gripping head opens with respect to the link plate, which simultaneously retracts the pivot bearing opposite the front edge of the gripping head when opening against the support surface of the film on the link plates, so that a film or other Gripping goods are easier to insert.
  • the distance between the pivot bearing and floating bearing between 20 and 40%, preferably between 25 and 35% of the width of the gripping head correspond.
  • Such a lever ratio causes a correspondingly large opening of the gripping head relative to the link plate or a corresponding bearing surface of the gripping head.
  • the floating bearing between gripping head and guide pin may comprise a pivot pin which is connected to the guide pin.
  • the round shape of the pivot pin allows a relative movement to the gripping head or a corresponding floating bearing receptacle on the gripper head even with a rigid connection with the guide pin.
  • the pivot pin also be rotatably anchored in the guide pin, the friction between the pivot pin and a corresponding floating bearing guide can be minimized by a relative rotation of the pivot pin, thereby virtually preventing wear.
  • a variant of the present invention provides that at least one link guide is provided on the gripping head, in which the pivot pin is received and guided.
  • a link guide which, for example, as a surrounded by a lever or web slot, which protrudes on the underside of the gripping head is a relatively simple solution for the leadership in a floating bearing, which allows a sliding attachment with a simultaneous fixation of the gripping head on floating bearing.
  • a floating bearing in the form of an open guide portion is conceivable in which the fixation of the gripping head is realized at the floating bearing by acting on the gripper plunger spring means. For a uniform distribution of the force applied by the guide pin force two slide guides can be provided.

  • the rotation of the guide pin reduces the degrees of freedom of the connection between the guide pin and gripper head in the floating bearing. Without such a rotation lock a much more complex recording of the guide pin in the gripping head would be necessary to prevent rotation of the movable bearing relative to the pivot bearing.
  • the guide section may be formed as a flattened section on an end of the guide pin facing the gripping head and the gripping head has a recess for receiving and interacting with the guide section, i. the head of the guide pin with flattened portion having. Due to the coordinated design of the guide section on the guide pin with the recess in the gripping head no additional components or additional processing stations are required for the rotation in the production.
