Large area vacuum fixture system meets personalized needs

Germany Fresenius scarby Pharmaceutical Co., Ltd. needs to stack 5 layers for each pallet, 9 full cartons for each layer, and each carton filled with infusion bags weighs 8 kg. In this way, a total of 10.6 pallets are required for 480 cartons, and the full pallets are transported out of the loading station through the conveyor belt. In other words, 11 pallets must be supplied to the stacking station every hour to meet the capacity needs. This means that the palletizing robot needs to perform many processes: it needs to carry not only 480 cartons, but also 11 pallets. Conversely, if mechanical fixtures are used, they must be replaced frequently, at least 11 times per hour within the same functional range, to handle these two different workpieces. If it takes a few seconds to change each time, the total time consumption under the multi shift system is considerable. This is obviously not conducive to the utilization of pallets; If you use a set of mechanical clamps that can clamp pallets and cartons at the same time, not only will the clamp be large and very heavy, which will seriously affect the motion speed of ABB robots, and even require robots with larger loads and more expensive. How can the robot break through the bottleneck and complete the whole palletizing work with higher speed and efficiency? SCHMALZ, a professional manufacturer of vacuum systems, has provided an effective solution to this tearing problem

with years of experience in palletizing system design, SCHMALZ company has equipped ABB palletizing robot with SCHMALZ large-area vacuum fixture system. The fixture system consists of five modules: the external four modules adopt SCHMALZ large-area vacuum fixture fx-400/120 SV, which is used to clamp three cartons for stacking each time, which is equivalent to one-time 3 × Total handling weight of 8kg; The pallet is clamped by a SCHMALZ large-area vacuum fixture fx-600/80 SW module in the middle of the fixture system

the reason why two different vacuum fixture modules are selected to form a fixture system is that the number and technology of vacuum units of these two vacuum fixture modules are different. The vacuum fixture with "SV" (check valve) system can better handle cartons, because all its vacuum units will automatically close when they do not contact the loaded workpiece (only 40% coverage is required, all vacuum units contacting the loaded workpiece can achieve their maximum suction), so as to ensure the vacuum degree of other vacuum units; The vacuum fixture system with "SW" (throttle valve) technology is the best choice for handling pallets with rough and porous surfaces, and the vacuum unit is also less likely to be blocked by wood chips and debris of the pallet

schmalz intelligent large area vacuum fixture system. On the one hand, it is designed and configured according to the modular standard, on the other hand, it is configured with a fast transfer switch between two different fixture systems. The customer only needs to set the program in the operating system of ABB palletizing robot. When the robot controller starts to start, the robot can automatically convert the vacuum suction module according to the setting instruction and its detection system, so as to absorb pallets or cartons and move them to the designated station without losing operation time

the multifunctional design of the vacuum fixture system, combined with the multi-stage vacuum generator of s future chmalz, is more compact and lightweight than the mechanical fixture, and can make full use of the power of ABB Robot, especially when the robot moves under no-load state

seeing the greatly improved production efficiency and the sharp drop in production management costs, German Fresenius scarby Pharmaceutical Co., Ltd. is very satisfied with this new robot vacuum fixture system that can handle cartons and pallets at the same time. Including handling pallets, abb palletizing robots must perform about 200 work cycles per hour to complete the process of stacking up to 5 layers of 9 cartons per layer on pallets (3 cartons are handled at the same time each time). Without the perfect and close cooperation between SCHMALZ large-area vacuum fixture system and ABB Robot, such work efficiency is completely impossible to achieve in practical application

the person in charge of Fresenius kabi Pharmaceutical Co., Ltd. in Germany said that this set of palletizing system solution combines the technical and experience advantages of ABB and SCHMALZ, and its efficient and stable characteristics far exceed their expectations and successfully meet their requirements. Fresenius kabi Pharmaceutical Co., Ltd. in Germany has begun to plan to purchase another set of similar flexible automation system, so as to completely liberate employees from boring stacking operations and turn to more challenging jobs
