The invention is based on the packing gripper system as per definition in the generic term of claim 1, wherein a load carrying device is part of a carrying and handling station by means of which gripping, clamping, lifting as well as vertically directed depositing of individual plate and individual sheet packages into suitably sized and only slightly larger sized container openings of holding and storage containers can be carried out.
For this purpose, the load carrying device must be equipped with an expedient and fail-safe motion drive, which enables the gripper fingers to perform horizontally directed gripping and clamping and vertically directed lifting and setting down operations. In this case, the load carrying device is to be designed as an outside gripper provided with vertical clamping faces on the inner sides of its gripper fingers.
The state of the art in such load carrying devices is characterized by motion drives of different types and designs as well as different clamping jaw and gripper finger arrangements. As examples of further, in particular load-dependently designed load carrying devices, some of the published outside gripper solutions are described in the invention disclosures indicated hereinafter.
Subject matter of
is a gripping device for battery modules and publication
relates to a carrying device for lifting and lowering loads, in particular electromechanical or electrical components, with their vertical movements requiring attachment of their center ring lugs to a crane hook or to a separate load suspension gear with hooks of a crane and the horizontal gripping element adjustment and movement of which require manual operator action. The crossbeam arrangements make a stepped or pivoting gripping element configuration necessary and necessitate large space requirements for these load carrying devices.
The load handling system for packaged piece goods as per description in
has a space-saving design of its gripper fingers. The load suspension gear for attachment to a crane has an elaborate and multi-component structure and cannot be steplessly adjusted.
Subject matter in
is a pair of tongs for lifting heavy loads, with the individual workpiece or workpiece package being gripped via a scissors-type lever system making use of swiveling grippers with a steplessly adjustable gripper spacing. This gripper system is provided with a hydraulic motion cylinder that moves the grippers in the vertical main stroke direction and so-called gas pressure cylinders for the horizontal as well as the pivoting movement of the grippers in their auxiliary stroke direction as autonomous and independent energy sources of the movement drive. Its structure is therefore complex and of multi-component design. The arrangement and movement of the gripping elements of this load carrying device occupy a great amount of space.
The drive element of an electrically self-sufficient load handling gear as described in
is a spindle driven by an electric motor for the closing and opening movement of the gripping means designed as gripper tongs with pivoting gripper jaws. The electrical power source for this load carrying device are accumulators arranged on a separate crossbeam.
Disadvantages of these prior-art load carrying devices are summarized as follows:
The objective that must be accomplished is to design the load carrying devices in packing gripper systems in such a way that they
The problems described hereinbefore of prior-art systems relating to the design of load lifting means and load carrying devices as outside grippers for vertical clamping surfaces on plate and sheet packages consisting of individual plates and individual sheets and for comparable individual components and component packs that need to be lifted are solved by the characteristics stated against patent claim 1.
The load carrying device, herein referred to as packing gripper system, is designed for the vertically directed depositing of previously gripped, clamped and lifted packages or stacks of plates and sheets into holding and storage containers provided with suitably sized and only slightly larger sized container openings. The packing gripper system consists of a frame rack with a drive module being arranged on the upper side of this rack. The drive module is designed in the form of an electric cylinder and comprises a linear drive which is powered by an electric motor and moving in vertical direction back and forth between two end positions. This linear drive is motionally connected to a gripper finger load carrying device via the scissor joint lever assemblies which are symmetrically arranged below each other and attached to the front of the frame rack. The gripper finger load carrying device is attached to the underside of the frame rack. Said device is equipped with two horizontally directed gripper finger carriers which project over a holding and storage container and are movable in the horizontal direction. The gripper finger carriers each support at least three slat- or rod-shaped bend-resistant rigid gripper fingers, which are arranged on both sides, vertically oriented and attached to them, and by means of which a plate and sheet package or stack, resting flat against and between the gripper fingers, is clamped between them at the retaining and pressing force exerted by the drive module, held vertically and horizontally oriented and accurately lowered into position and secured in the holding and storage container.
