Definitions

  • the present invention relates to a method and a device for packaging plate-shaped Workpieces that are combined into workpiece stacks and in packaging is brought in.
  • the present invention is based on the idea that collecting and aligning the plate-shaped workpieces on the one hand and the insertion of the workpieces into packaging on the other hand, they are decoupled in space and time.
  • the at least one workpiece stack for insertion into the Packaging on a movable in the direction of insertion Device is stored, which is preferably through openings in reaches through the packaging.
  • the alignment station a has first gripping device which between the Collection position and the packaging position is movable. It is particularly preferred that the first Gripping device of the at least one workpiece stack from the Collection station is recordable, and in particular at the same time can be aligned. Accordingly, the gripping device according to the invention with a number of tasks one constructive element, namely recording the at least one workpiece stack from the collecting station, aligning the at least one workpiece stack and finally the procedure of at least one Workpiece stack in the packaging position. In this way the device according to the invention receives a simple one Construction that still has a high number of functions can execute.
  • the alignment station additionally has a second gripping device, by means of which the inserted packaging can be moved and in particular in relation to can be aligned on the at least one workpiece stack.
  • the pair of pliers can be designed in various ways, provided that Gripping and aligning the at least one workpiece stack or the packaging is enabled.
  • a configuration has proven to be advantageous is designed such that the pair of pliers itself a Has essentially unchangeable shape, and gripping and aligning is done by having the pliers face up to the at least one workpiece stack or the packaging be brought up.
  • the Areas of the pair of pliers that match the at least one Work piece stacks come to the plant, in the plant direction taper slightly to ensure a secure grip and alignment to ensure.
  • the first and the second gripping device especially the first and second pair of pliers, in fixed Positional relationship to each other, and in particular are movable together. This ensures that with the approach of the gripping devices to the at least a workpiece stack or the packaging a defined, aligned state is brought about, unchanged is maintained until the gripping devices at least one stack of workpieces or the packaging again release.
  • the first gripping device is a device for inserting the at least one workpiece stack into the Has packaging. It has proven to be particularly advantageous proved that the device for insertion through pivotable expansion tabs is formed, which is preferably on the first pair of pliers are provided. These spreading tabs can, as soon as the at least one to be packed Workpiece stack and packaging for insertion stand ready to be pivoted out to edge sections the packaging comes to the plant and spread it open, so that the at least one stack of workpieces cant the packaging is avoided.
  • a fast, intermittent packaging process also requires that the stack of workpieces placed in a package are quickly conveyed out of the packaging position to the not to impede further process flow.
  • a third gripping device especially a third pair of pliers, which between the Collection position and an output position is movable.
  • This third gripping device enables one with packaging filled with at least one workpiece stack recorded immediately after the packaging process and in the dispensing position can be moved to where it is subsequent packaging process does not interfere.
  • the work cycle is automatically coordinated the third gripping device on the first and second To achieve gripping device, it is according to the invention preferred that the third gripping device with the first and / or second gripping device is coupled.
  • the packaging process itself can thereby be further simplified and accelerated that the Packaging station has a lifting device, by means of which the at least one workpiece stack in the Movable packaging position and especially in the Packaging can be inserted.
  • a lifting device by means of which the at least one workpiece stack in the Movable packaging position and especially in the Packaging can be inserted.
  • the Lifting device is formed by plungers or telescopic bolts, which can be extended linearly.
  • the first gripping device has at least one has another pair of pliers, preferably with the first Pair of pliers is coupled. That way they can individual workpiece stack each by means of a corresponding pairs of pliers recorded, aligned and be moved. It is particularly preferred that the at least one additional pair of pliers on the first pair of pliers can be moved to and from this. This allows the distance be varied between the individual workpiece stacks, for example to put them in the desired order for the Bring packaging and if necessary separating elements between the Pinch workpiece stacks.
  • the device at least a separating element device for insertion a separating element, in particular a strip of cardboard or the like, between adjacent workpiece stacks having. Taking into account the extremely fast Work cycle by the device according to the invention is left to insert the separating element only a very short time interval.
  • Separating element device ensures that the Efficiency and operational safety of the device there are no time constraints when inserting the separating elements is affected.
  • the separating element device is a device for cutting the separating elements and / or spreading cheeks for holding or Release a separating element. This will make a fully automatic and rapid operation of the device allows.
  • step A the workpieces are first checked with regard to on quality features such as surface quality, Dimensions, etc.
  • step B are based on the workpiece inspection Workpieces of poor quality (second Choice) and removed in step B '. Those Workpieces that are of sufficient quality are collected in step C and to Workpiece stacks summarized.
  • Process step B ' a packaging box laterally conveyed. The packaging box was previously from a Cardboard stack removed with a suitable device folded and placed in a cardboard buffer. Subsequently the tool stack formed in method step D in inserted the packaging box in this way The package formed is transported out in method step E.
