摘要： A workpiece transport system for an automated assembly line has a rail guide (11) with conductor rails (18) that extend along at least part of its straight sections (17). Current collectors (19) associated to the conductor rails (18) are arranged on a transport carriage (14), ensuring the current supply of the electric drive of the transport carriage (14) and/or acting as charging contacts (16) for the accumulator (33) of the transport carriage (14). The transport carriage (14) has control means (32) which switch the current supply of the electric drive from an external energy supply to a supply by the accumulator and vice-versa and/or which selectively use the external current supply to charge the accumulator (33). Alternatively, the rail guide (11) has at least one branch (20) which forms a buffer-station (21) for the transport carriage (14), charging contacts for the accumulator of the transport carriage (14) being provided in the area of the buffer-station (21).

摘要： Proposed is a transport system with self-powered workpiece carriers in the form of trolleys and with a branched rail network, the system enabling workpiece-transfer times to be reduced to the minimum. This is done by collecting trolley movement data and external signals using sensors (30, 52, 53) and switching means (50, 54). A microprocessor (10) is linked to the trolley drive unit (12) and brake system, and accelerates and decelerates the trolley, powering it to give the shortest possible workpiece-transfer time. In order to achieve the highest possible rates of acceleration and deceleration, the microprocessor (10) determines, from the speed pick-up characteristics of the trolley, the instantaneous mass of the trolley. By modifying the response threshold (27) of the trolley-separation sensor (30) to the prevailing situation, it is possible to maintain a high trolley frequency. Timely processing of the signals (31) from the trolley-separation sensor (30) by the microprocessor (10) enables several trolleys travelling one behind the other to be accelerated almost simultaneously. From the sequencing logic of the trolley-movement and control signals fed to the microprocessor (10), the microprocessor determines the position of a trolley in a line of trolleys waiting to approach a stopping point.

摘要： In systems of the kind described, each transport trolley (14, 14a) is fitted with sensors which scan the surface (20) of the trackway supports (22, 24) and block the trolley drive unit (16) if the trolley runs off the trackway. This arrangement does not, however, permit system conformity to be monitored with sufficient certainty, nor does it prevent unauthorized use of the trolleys (14, 14a). In order to increase safety, it is proposed that at least one trackway wall surface (28, 42) scanned by the sensors (40, 70) on the trolleys (14, 14a) is located on a trackway support (22, 24), next to a running surface (20) and at an angle to the running surface. The preferred field of application is in systems with flexible trackway or assembly networks in industrial manufacturing facilities.

摘要： Described is a device and process for charging the battery of a self-powered electric transport vehicle, in particular self-powered transport trolleys in workpiece-transfer systems. The device is characterized in that a charge-control unit (15) is fitted in the transport vehicle (11), the charge-control unit including a processor (24) connected to at least one memory unit (23), a device (33) for determining the battery charge status and a device (25) for regulating the charging. In the process disclosed, the charge status is compared by the processor (24) in the transport vehicle (11) with at least one reference level and the result used by the processor (24) to control the charging in such a way that the battery (14) is charged at least to the reference level stored in the memory unit (23), in particular to the minimum level required for the vehicle to reach the next charging station (16) or to a pre-determined maximum level.

摘要： Proposed is a transport system comprising a branched rail network on which autonomous workpiece carriers in the form of trolleys can move. The system exhibits a high degree of safety in non-regulation operational situations. Several independent devices are used for this purpose, but designed to function particularly well together. One embodiment includes a signal-processing logic circuit based on a microprocesser (10), the logic circuit monitoring for plausibility the flow of trolley movement data and external signals and halting the trolley if necessary. In a second embodiment, the tilting front end (13) of the trolley is designed as a two-stage buffer, the first buffer state (34) being produced by a light impact, the second (35) by a hard (non-regulation) impact. Another embodiment calls for the trolley to be fitted with a shock sensor (24) responsive to a hard (non-regulation) impact. Another embodiment calls for an energy-consumption monitoring device (40) which determines the amount of energy taken from the batteries during a particular time interval T and compares it with a pre-determined threshold value (46), halting the trolley if the threshold value (46) is exceeded for too long a period of time.
