The production rates of carbon fiber reinforced plastic (CFRP) parts are rising constantly which in turn drives research to bring a higher level of automation to the manufacturing processes of CFRP. Resin transfer molding (RTM), which is seen as a production method for high volumes, has been accelerated to a high degree. However, complex net-shape preforms are necessary for this process, which are widely manually manufactured. To face these challenges a new concept for the manufacturing of carbon fiber preforms with a form-flexible gripping, draping and joining end-effector is presented and discussed. Furthermore, this paper investigates the application of this concept, describes the initial build-up of a demonstrator, focusing on material selection and heating technology, and discusses test results with the prototype. This prototype already validates the feasibility of the proposed concept on the basis of a generic preform geometry. After a summary, this paper discusses future in-depth research concerning the concept and its application in more complex geometries.

“…Since the MPR provides varied equipment, such as a coupler, stirrer, reactive and separation meters, and a scrubber, the MPR is able to conduct all the processing tasks depending on a station. It is not impractical to assume this kind of a multifunctional robot, as suggested in [30] and [31]. As for the discharging of a final product and cleaning of the empty vessel of the MHR, these are requisite processes in one production batch; therefore, exclusive stations are set up for each of them.…”

In this paper, we focus on a batch manufacturing system with multiple industrial robots. In this system, material-handling robots (MHRs) and material-processing robots (MPRs) are operating. Since various operations are conducted at certain places, one of them might include a localized bottleneck. A localized bottleneck is a constraint that dominates the maximum amount of production in a system, that is, the productivity. In addition, the bottleneck induces congestion; as a result, the productivity declines. For these issues, there are two primary challenges: bottleneck prevention and restraint. To solve them, suitable operational techniques with respect to the MHRs and MPRs are needed in order for them to operate appropriately while relating to each other. In this paper, a constructive approach toward multi-robot coordination problems is taken. In this approach, we propose applicable operational techniques for the robots. Through simulation experiments, we examine the effectiveness of the proposed techniques and their combinations and, finally, show an integrated operational technique. Each of the operational techniques solves a localized bottleneck and the congestion, and the integrated technique successfully improves the productivity and results in the most efficient system.Note to Practitioners-The primary motivation for this study was the pursuit of answers to the problems associated with production operations for a pipeless batch plant system in chemical process industries. These solutions will also apply to other manufacturing systems for high-mix low-volume production with a number of machines or robots. In many previous studies, scientists addressed the optimization problem of production scheduling; in this study, however, we focus on a simulation study and aim to develop an applicable integration technology for the coordination of operating robots in the interest of the automation of a highly flexible production activity. In practical batch manufacturing systems, as an entire operational strategy, it is necessary to equalize the flow of products, i.e., bottlenecks, throughout the system. Furthermore, once a localized bottleneck appears, its harmful effect on the system has to be restrained. Therefore, we suggest efficient operational techniques to tackle these challenging issues. Through various simulation experiments, we show that some good combinatorial techniques enable to improve productivity. The results of this paper are feasible and sufficient for flexible batch manufacturing systems, but the application is limited to a system in which the safety of production operations and processes is guaranteed. In future research, we will address design problems regarding safety and reliability in a plant system.

Robotics has been introduced in industry to replace humans in arduous and repetitive tasks, to reduce labour costs and to ensure consistent quality control of the process. Nowadays robots are cheaper, can work in hostile and dirty environments and they are able to manipulate products at high speed. High speed and reliability and low robot gripper costs are necessary for a profitable pick and place (P&P) process. However, current grippers are not able to handle these products properly because they have uneven shapes, are flexible and irregular, have different textures and are very sensitive to being damaged. This review brings together the requirements and phases used in the process of manipulation, summarises and analyses of the existing, potential and emerging techniques and their possibilities for the manipulation of fresh horticultural products from a detailed study of their characteristics. It considers the difficulties and the lack of engineers to conceive of and implement solutions. Contact grippers with underactuated mechanism and suction cups could be a promising approach for the manipulation of fresh fruit and vegetables. Ongoing study is still necessary on the characteristics and handling requirements of fresh fruit and vegetables in order to design grippers which are suitable for correct manipulation, at high speed, in profitable P&P processes for industrial applications.Additional key words: food manipulation; horticulture grasp; postharvest science and technology; robotic product handling. ResumenRevisión. Tecnologías en garras robotizadas para operaciones de coger y dejar productos hortofrutícolas frescos La robótica ha sido introducida en la industria para reemplazar a los humanos en tareas arduas y repetitivas, reducir mano de obra y para asegurar una calidad constante de los procesos. Actualmente los robos son más baratos, capaces de manipular productos a alta velocidad y de trabajar en ambientes hostiles. Por tanto, los robots pueden trabajar en operaciones de "coger y dejar" (pick & place, P&P) con frutas y hortalizas frescas. Para un proceso rentable de P&P, son necesarias una alta velocidad y fiabilidad, así como un bajo coste de los sistemas de agarre. Este artículo de revisión recopila las necesidades y fases empleadas en el proceso de manipulación, reuniendo y analizando las técnicas existentes, potenciales y emergentes y sus posibilidades de aplicación para la manipulación de productos hortofrutícolas frescos a partir del estudio detallado de sus características. Considera las dificultades y la falta de ingenieros para concebir e implementar soluciones. Los autores proponen las alternativas más prometedoras para acometer este difícil problema y consideran la necesidad de seguir estudiando las características de frutas y vegetales frescos y las necesidades de manipulación. Las garras de contacto con mecanismos infra-actuados y ventosas o agarrar el producto sin contacto pueden ser las alternativas más prometedoras para manipular frutas y vegetales frescos. Es necesario continuar e...
