Abstract
To give the reader a tasty incentive for learning, almost all the examples in this book are related to a chocolate machine. The focus here is on MC. This means that only machine elements that involve motion control, such as material transport and packaging, are listed. The system shown in Fig. 2.1 consists of individual modules, each of which can be viewed in separate exercises. Dividing a complex system into individual machine modules is widespread practice, as modularization allows automation solutions to be reused for new projects. Many of the machine module designations listed in this book are widely used, so that they can be found in the general language of machine builders today. These include, for example, designations such as winder or flying saw. As the focus is on the packaging of the chocolates, the actual production process of the chocolates is simplified in a single machine module. As the focus is on the packaging of the chocolates, the actual production process of the chocolates is simplified in a single machine module. A recipe mix is not part of the PLCopen documentation. The individual steps of the packaging system are described in more detail below. Each of the machine modules shown contains a series of motion tasks that can be solved very well with MC according to PLCopen. In the example chapters, the authors go into more detail about some of the machine modules. The modules are arranged in an almost closed loop. The material flow of the individual packaging steps runs counter-clockwise. It begins at the bottom left-hand edge of the picture with the unwinding of packaging material and ends at the left-hand edge of the picture, where the loaded pallets are conveyed out of the system by a rotary table. The production of chocolates (shown here in simplified form) takes place in the Product and Tray Generation machine module. This machine module consists of two parts. At the top, the ingredients for the chocolates are placed on a conveyor belt through three tanks. This completes the simplified production process for the chocolates. At the same time, small packaging units for the chocolates are produced from the unwound packaging material. This is done by forming plastic discs from the packaging material using a tray insert with indentations for the chocolates. Both the chocolates and the trays are fed to the Picker Cell machine module by a separate conveyor belt. In this module, the chocolates are picked from the conveyor belt by a delta robot and placed in the tray on a second conveyor belt. Delta robots are often used in picker cells, as their physical properties enable extremely high pick rates. The individually wrapped chocolates are then transported to the Flow Packer machine module via additional conveyor belts. The conveyor belt track between the Picker Cell and Flow Packer makes it possible to adjust the distance between the trays filled with chocolates. Such a cascade of three or more conveyor belts is also known as a Smart Track. The Flow Packer applies a foil to the trays. To do this, the foil is unwound, glued on and finally cut with a rotary cutter (rotary cross cutter). Cartons are required for further packaging steps. The small cartons can hold three trays. They are assembled by the Case Erector at the right-hand edge of the picture and placed on a conveyor belt. The conveyor belt with the assembled cartons is operated in cycles. This means that it does not move continuously, but moves and stops alternately. Another module, a Magic Track, picks up three trays at a time on its carriage and guides them to a horizontal pusher. The pusher always pushes three trays at a time into an assembled carton. At this point the conveyor belt is stationary. This is a comparatively simple way of cartoning. There are much more complex machines that can also close the flaps on cartons. For our example machine, however, we will make do with a pusher. Further larger cartons are inserted into the packing loop at the top right-hand edge of the image, positioned and then guided parallel to the small cartons to the next machine module. This is known as the Cartoning Robot. The main component of this module is a Scara (abbreviation for Selective Compliance Assembly Robot Arm). In the machine, the Cartoning Robot has the task of filling the large cartons with several small cartons containing the trays. These filled cartons are stacked on a pallet by another robot to save space. This machine module is referred to below as a Palletizing Robot. A special feature of this type of robot is a parallelogram at the back of the arms, which always keeps the hand axis in the same alignment to the floor. The boxed chocolates leave the machine via a rotary table. The special feature of the Rotary Table is that there are always two ways to reach a position. The selected modulo function decides which direction is better.
