This paper deals with an industrial problem of plastic wrapper removing. This trends to given a new innovation in the field of recycling. From this contribution all kind of water bottles having eligible to remove the unwanted labels for further reconstruction. Thus, this paper focus on the design of label wrapper machine to remove the PVC 38&40-Micron label around the specially shaped cool drinks bottles. The metal brush through the power of electric motor can remove the label effectively. Recycle process which plays virtual role in all over application but, reuse and recycle process is only thing of plastics application. However modern technology food and cool drinks are contain inside of plastics container. But, our aim is to be recycle the plastic without any additional of colour, odour and taste. Human source never fulfil maximum efficiency work. Hence, in this project which utilized new trends and reduce the human work for further implementation from its construction. Hence hear by the high power machine to solving the above issue with addition of metal brush to remove the labels constantly.

Abstract The ongoing tendency toward the electrification of hydraulic systems, mainly in the form of self-contained solutions, poses design challenges in high-power applications. An electric motor drives positive-displacement machines used to control the motion of the hydraulic actuator (nonhybrid systems encompassing one or two pumps exist in the technical literature). All the power managed by the actuator passes through the electric motor, which leads to often oversized arrangements. These detrimental characteristics are especially pronounced when the power level increases approximately above 35–40 kW. Therefore, this research paper presents and studies a self-contained, electro-hydraulic, hybrid architecture intended to downsize the electric motor while maintaining the high-power output of the nonhybrid counterpart. After introducing the sizing process for the energy storage device and developing a suitable control strategy for the hybrid subsystem, the proposed concept is validated via high-fidelity dynamic models. The rated power of the electric prime mover can be cut by 70% in the considered application (a mid-size, knuckle-boom crane with an installed power of about 46 kW) without altering the performance in terms of motion control. The additional mass (about 310 kg) of the hybrid system is not expected to affect the load-carrying capacity significantly. As a result, the hybridization of self-sufficient systems is technically feasible for high-power applications. Drawbacks related to the system cost-effectiveness might, however, be experienced. An application-driven cost analysis should be conducted before implementing such a solution.

High Power Efficiency

In work theoretical bases of an adaptive robotics are stated. The adaptive robotics considers creation, research and designing of robots with adaptive electric drives of modules. The adaptive drive contains the electric motor and the adaptive gear mechanism possessing property independently to change output speed of movement depending on loading. This property of adaptation is named by self-regulation. Self-regulation is carried out only for the account of mechanics and does not demand management. The adaptive drive demands smaller capacity, overcomes emergency overloads, is structurally simple, has small dimensions and weight. These advantages are especially important for intermediate modules of the manipulator. Use of adaptive drives procures high power efficiency of the robot.

Load Modulation

This paper presents an approach to power added efficiency (PAE) increase for Quasi-Doherty power amplifier (Q-DPA) design. For this aim, active feedback is utilized instead of a passive quarter wavelength transmission line (TL) usage, which is conventionally used in the DPA schematic. PAE increase can be done by applying an accurate load modulation to the main amplifier (PAmain), especially for technologies in which output impedance of the main power amplifier (Zout,main) considerably varies in both low and high power regions. Because such precise modulation is still based on a modified TL, this approach suffers from the inherent narrowband behavior of that TL. As a consequence, expecting a wideband DPA may not be satisfied in all cases. To deal with this issue, active feedback is used to play a role in reaching PAmain, which is not saturated before, to its maximum efficiency at the highest level of received input power (Pin) in the high power region. Following Zout,main trajectories in power and frequency sweeps simultaneously just by a passive TL are not needed anymore. Still, for the sake of preventing total PAE degradation due to the consummated power by the feedback path’s power amplifier (PAfeedback) should be limited, analytical confinement is provided in this work. A comparison is made between GaAs pHEMT 0.25um MMIC technology-based conventional DPA and the proposed revised approach based-DPA to verify the mentioned approach. The proposed PA shows maximum output power of 33.4 dBm, maximum PAE of 41.6, fractional bandwidth of 11%. The Q-DPA works with a maximum power gain of 24.16.

In Ukraine, the number of farms, private land users and protected soil structures has increased significantly in recent years. To increase the efficiency of vegetable production, small-sized mobile units in the form of motoblocks with internal combustion engines of domestic and foreign production have been widely used. However, during the operation of mobile units with internal combustion engines in greenhouses and hotbeds, the noise level and air pollution increase, which negatively affect not only people but also plants. The disadvantages of motoblocks with internal combustion engines should also include a fairly high specific consumption of liquid fuel, which has a high cost, difficulties in starting and stopping the unit, as well as the relatively low reliability of the internal combustion engine. More promising for work in protected soil structures are mobile units with traction motors, called electric motors, as environmentally friendly units that do not have these shortcomings. The main technical characteristics of the experimental sample of a small-sized electrified soil-cultivating motoblock are given in the work. The structural scheme of the power energy channel of the electric motor unit is substantiated, which clearly demonstrates the processes of energy conversion in it. The equation of energy balance of the electric motor unit and the main energy ratios that determine the properties of the traction motor in the drive of the electric motor unit are obtained. The algorithm of optimal control of a direct current traction motor by the maximum efficiency for direct current motors of serial and mixed excitation is substantiated. The results of field tests of the prototype of the electric motor unit are presented. The analysis of the obtained results of experimental researches of the electrified tillage motor-drive driven by the direct current motor of sequential excitation testifies to the reduction of specific energy consumption for the main types of tillage by 12-15%.
