Behind the packaging machines are the system components: highly flexible components such as robots for special tasks, the Vision System, our Transmodul transport robot, the Flowmodul flow-wrapping machine and the VMS packaging machine control system, which Schubert is continuously developing further.
The F2 robot has its origins in the legendary SNC-F2 robot built in 1984, and has been used several thousand times since. Controlled by two servomotors, the TLM-F2 can carry out any movements in a two-dimensional working field of 1.2 x 0.8 m. The F2 robot can be used to erect, fill and close boxes. The hand of the robot is designed as a tool exchanger which has all of the devices necessary to control tools. The robot arm can be accelerated at 3.6 G, reaching speeds of up to 2.4 m/s. Its lifting capacity is 40 kg.
The F3 robot was specially developed to remove packaging materials from magazines. Its three axes allow it to carry out this task efficiently. Once a few parameters have been entered, it can independently peel a box blank or plastic tray from the stack. The robot arm has a lifting capacity of 15 kg. A pneumatic clamping device at the wrist ensures the exact placement of the suction or gripper tool. Occasionally, the F3 robot is also used for diverse functions within other machine processes.
The F4 robot is a four-axis pick-and-place robot which in co-operation with the TLM Vision System picks products from a continuously running product belt and groups them in a box, tray or onto a Transmodul. If there are two F4 robots working in a single machine frame with one control unit and one Vision System, this is referred to as an F44 picker station. The F4 arm can accelerate with 10 G, reaching speeds of up to 4.7 m/s with a noise level of only 70 dB. F4 robots can work together as a team and mutually pursue the objective of guaranteeing packages which have been filled completely.
Due to the wide ranges of products in picker lines, the Vision System works together with the TLM scanner which was specifically developed for packaging tasks. Scanners are built at 200 mm steps up a length of 1,800 mm.
There are transmitted light scanners which record a shadow image of the products and reflected light scanners which look at the products. Reflected light scanners are also offered in a 3D design to evaluate height information. The TLM Vision System can evaluate up to 4,000 products per minute while carrying out an individual quality check.
The Transmodul is the world’s first transport robot for packaging machines. It has an inductive power supply. This allows the Transmodul to move freely. Data and signals are transmitted wirelessly. To hold cartons and products in place during transport, the Transmodul is equipped with a vacuum blower that generates a vacuume of 0.04 bar. The maximum acceleration is 3 G. This allows it to reach speeds of up to 4.5 metres per second. The Transmodul runs on a rail system that passes through all the sub-machines. The Transmodul has made it possible to build redundancy into packaging machines for the first time. If one Transmodul fails, the availability of the machine is not affected. Transport tools are exchanged for a size change. A maximum of 32 Transmoduls can move on a rail section.
The Flowmodul, the world’s first fully integrated packaging machine for flow-wraps, making it possible to package confectionery, food, cosmetics and pharmaceutical items into flowpacks is as simple as never before.
The flow-wrapping component is fully integrated into the tried and tested top-loading packaging machine system, setting new standards for quality control, efficiency, space requirements and flexibility.
The operator guidance system is the master computer of a TLM packaging line. It contains the blueprints for the machine and knows all the spare parts, so it can provide information on all the components at any time. The complete operating manual including information regarding operation, format change-over and maintenance. It is the human/machine interface. There are only two operating buttons to switch it on and off. Several operator guidance systems can be installed in one TLM machine.
The machine frame, which is welded from sheet-metal parts, is the torsion-resistant machine cell used to house all the components. Large safety doors provide good access to all the machine’s functions. Operating elements are located in the hinges, while modern LED lamps signal the operating mode of the individual sub machines. These machine frames are available in 40 different dimensions. They are either coated or made of stainless steel plate.
