Definitions

  • the present invention relates to a method and an apparatus for packaging plate-shaped workpieces, which are combined into workpiece stacks and introduced into a package.
  • a packaging board is provided at the end of a conveying path on which the plate-shaped workpieces are conveyed, in which the workpieces are conveyed directly and individually one above the other.
  • the workpieces fall depending on the degree of filling of the packaging by different drop heights in the carton, which can lead to insufficient alignment of the workpieces and possibly damage to the workpieces or the carton.
  • this procedure is relatively time consuming and clock-dependent. As soon as a carton with the desired number of workpieces is filled, it must be transported out of the filling position and it must be transported an empty carton in the filling position.
  • the workpieces are combined into stacks and slid on an inclined conveyor line inserted into a prepared box.
  • the cardboard in particular its side wall, is damaged by the impact of the workpiece stack.
  • the same applies to the workpieces themselves.
  • no satisfactory alignment of the workpieces is achieved.
  • US-A-3 479 795 discloses a device according to the preamble of claim 6.
  • the present invention is based on the idea that the collecting and aligning of the plate-shaped workpieces on the one hand and the insertion of the workpieces in a package on the other hand done spatially and temporally decoupled.
  • the advantages achieved by the method according to the invention and the device according to the invention are, for example, that an extremely high packaging capacity or packaging speed is made possible.
  • By decoupling the collecting and aligning of the workpieces on the one hand and the insertion of the workpieces in a package on the other hand it is ensured that the packaging process itself as well as the infeeding and outfeeding of the packaging, the collection and alignment of the workpieces not in time or clockwise or in 'other ways restrict. This ensures that continuously a very high number of workpieces can be conveyed by means of a conveyor line. This not only allows a higher than in the prior art increased packaging capacity or packaging speed, but also a trouble-free flow of the packaging process, which also contributes to a consistently high effective packaging capacity or packaging speed.
  • the picking up and simultaneous alignment of the at least one workpiece stack take place simultaneously with the alignment of the provided packaging with respect to the workpiece stack.
  • a parallelization of said method steps is achieved, which allows a considerable time savings and thus a further increase in the packaging capacity or packaging speed.
  • the at least one stack of workpieces is placed for insertion into the package on a movable in the direction of insertion device, which preferably passes through openings in the packaging.
  • This loading or lifting device allows, in particular when it passes through the openings in the packaging, a smooth insertion of the at least one stack of workpieces in the packaging, which increases the reliability and freedom from interference of the packaging process and at the same time contributes to a further increase in packaging capacity.
  • a separating element is inserted between adjacent workpiece stacks.
  • a reliable and rapid insertion of a plurality of workpiece stacks into a package is provided.
  • the insertion of a plurality of workpiece stacks can be advantageous in numerous situations, for example in order to be able to continue to use a specific packaging with changing workpiece dimensions.
  • the alignment station has a first gripping device, which can be moved between the collecting position and the packaging position. It is further provided that by means of the first gripping device, the at least one stack of workpieces from the collecting station is receivable, while at the same time is alignable. Accordingly, the gripping device according to the invention fulfills a number of tasks with a single constructive element, namely picking up the at least one stack of workpieces from the collecting station, aligning the at least one stack of workpieces and finally moving the at least one stack of workpieces into the packaging position. In this way, the device according to the invention obtains a simple construction, which nevertheless can perform a large number of functions.
  • the alignment station additionally comprises a second gripping device, by means of which the introduced packaging movable and in particular with respect to the at least one stack of workpieces can be aligned.
  • first and second gripping devices are preferably formed in each case by opposing, U-shaped devices, in particular by a pair of pliers.
  • the pair of pliers may be formed in a variety of ways, provided a gripping and aligning the at least one stack of workpieces or the packaging is possible.
  • a configuration has proved to be particularly advantageous which is designed in such a way that the pair of pliers themselves has a substantially unchangeable shape, and the gripping and alignment takes place in that the pliers are moved towards the end of the at least one workpiece stack or the packaging.
  • the surfaces of the pair of pliers, which come to rest with the at least one stack of workpieces taper slightly in the direction of contact in order to ensure secure gripping and alignment.
  • the first and second gripping devices in particular the first and second pair of pliers, are in fixed positional relationship to one another, and in particular can be moved together. This ensures that with the approach of the gripping devices to the at least one workpiece stack or the packaging a defined, aligned state is brought about, which remains unchanged until the gripping devices release the at least one workpiece stack or the packaging again.
  • the first gripping device comprises means for introducing the at least one stack of workpieces in the packaging. It has proved to be particularly advantageous that the device for insertion through pivotable expansion straps is formed, which are preferably provided on the first pair of pliers.
  • these expansion tabs can be swung out to abut against and spread open the edge portions of the packaging, thereby avoiding jamming of the at least one stack of workpieces on the packaging.
  • a rapid, cyclic packaging process also requires that the stacks of workpieces brought into a package be quickly conveyed out of the packaging position in order not to hinder the further course of the process.
  • the alignment station according to a development of the device according to the invention, a third gripping device, in particular a third pair of pliers, which is movable between the collection position and an output position.
  • This third gripping device makes it possible for a packaging filled with at least one workpiece stack to be picked up immediately after the packaging process and moved into the dispensing position, where it does not disturb the subsequent packaging process.
  • the third gripping device with the first and / or second gripping device is coupled.
  • the packaging process itself can be further simplified and accelerated by the packaging station having a lifting device by means of which the at least one stack of workpieces can be moved in the packaging position and, in particular, inserted into the packaging.
  • a lifting device by means of which the at least one stack of workpieces can be moved in the packaging position and, in particular, inserted into the packaging.
  • the first and optionally also the second gripping device of relieves additional process tasks, and the linear process of the at least one stack of workpieces into the packaging can be efficiently performed by a separate lifting device, which contributes to a further acceleration and improvement of the reliability of the process.
  • the lifting device is formed by plunger or telescopic bolt, which are linearly extendable.
  • the first gripping device has at least one further pair of pliers, which is preferably coupled to the first pair of pliers.
  • the individual workpiece stacks can each be picked up, aligned and moved by means of a corresponding pair of pliers.
  • the at least one further pair of pliers to the first pair of pliers to and from this wegfahrbar. In this way, the distance between the individual workpiece stacks can be varied, for example, to bring them into the desired arrangement for the packaging and possibly clamp separating elements between the workpiece stacks.
  • the device further comprises a separating element means for introducing at least one separating element, in particular a strip of cardboard or the like, between adjacent workpiece stacks.
  • a separating element means for introducing at least one separating element, in particular a strip of cardboard or the like, between adjacent workpiece stacks.
  • the separating element device has a device for cutting the separating elements and / or expanding cheeks for holding or releasing a separating element. This allows a fully automatic and rapid operation of the device.
