In the rise/fall section, an intake port is provided in a front part and an exhaust port is provided in a rear part, separately, and in the wrist section, an intake port is provided at a side close to the end effecter, and an exhaust port is provided at a side far from the end effecter, separately.

The disclosure relates to an overpressure encapsulation system for explosion protection, comprising the following: a device (1), in particular a painting robot (1), an overpressure-encapsulated device housing (2) comprising a housing outlet (6) for discharging gas out of the device housing (2), a compressed air system (3, 4) for operating the device (1), said compressed air system (3, 4) being arranged within the device housing (2), a sensor assembly (7, 8, 9) for measuring at least one fluid variable (Q, PI, PA), and an analysis unit (11) which analyzes the fluid variable (Q, PI, PA) measured by the sensor assembly (7, 8, 9), in particular in order to detect a leakage of the device housing (2). The disclosure proposes that, when a leakage of the device housing (2) starts, the analysis unit (11) ascertains a remaining run time until a required maintenance operation or until a system failure on the basis of the measured fluid variable (Q, PI, PA) and/or detects a fault (14, 16) of the compressed air system (3, 4) on the basis of the measured fluid variable (Q, PI, PA). The disclosure further relates to a corresponding operating method.

A painting robot which can prevent the introduction of air from the nozzles into paint during the color change of paint and filling of paint and can prevent the acceleration of wear of the pump, and sufficiently remove dissolved gas from the paint. The painting robot includes a paint supply path connected to the paint supply side of the nozzle head and a return flow path configured to recover the paint not discharged from the nozzles. Further, the painting robot includes a first filter configured to remove foreign matter in the paint and a second filter configured to separate dissolved gas from the paint. When paint is not discharged from the nozzle head, the control unit opens the on-off valve and circulates the paint to the bypass flow path.

A seal belt includes inner and outer belt sections. The inner belt section revolves according to the movable member movement. The outer belt section includes, between the inner belt section and an opening, a first portion in which a first end is retained at a movable member inside section portion, the portion being closer to the opening lower end, and the remaining portion extends along the opening and is retained at a third space position, and a second portion in which a first end is retained at an inside section portion, the portion being closer to the lower end, and the remaining portion extends to a fourth space position along the opening and is retained at the fourth space position. The first portion and second portions lengths are changed in a complementary manner according to the movable member movement. The drive mechanism is surrounded by the inner belt section.

A protective drape for a robotic system is provided. The protective drape may be used with robotic systems that are required to operate in varied environments that illustratively include industrial applications, a sterile surgical suite for patient care, and a clean room for manufacturing sensitive electronic components. In each of these applications, there is a need to prevent contaminants from infiltrating from the environment to the robot and affecting operation of the robot itself or the robotic system, as well to prevent contaminants from the robot from infecting a patient or contaminating an assembly or process product.

An air purge mechanism includes: a plurality of containers accommodating electrical connection parts; and a cable connecting the containers. One of the containers is provided with an air supply port through which compressed air is supplied to the container. The cable includes a wire bundle formed by bundling a group of wires connected to the electrical connection parts, and a sheath covering an exterior surface of the wire bundle. The interior spaces of two of the containers are connected to each other via gaps between the wires inside the sheath.

Provided is a joint structure for a robot which can prevent leakage of a lubricant which is charged to the interior of the joint structure while improving a drip-proof property. The joint structure for the robot includes: a first arm which is hollow; a second arm which is rotatably mounted to the first arm; a power transmission mechanism which is provided adjacent to the outside of the first arm, the power transmission mechanism including a gear and an inner space which houses the gear and is charged with a lubricant; a booster section which increases a pressure in an interior of the first arm to be higher than an outside pressure; and a one-way communication section which allows the interior of the first arm and the inner space to communicate with each other and a gas in the interior of the first arm to flow into the inner space, while preventing the lubricant in the inner space from flowing out to the interior of the first arm.

An object is to exhibit a higher sealing performance against an external pressure, to more reliably prevent breakage of a sealed state established by an inner seal member, and to maintain the soundness of inner mechanical components. Provided is a joint structure including two joint members, a driving mechanism that rotationally drives the two joint members about a predetermined axis relative to each other, two seal members forming a seal between the joint members at positions doubly surrounding the outside of a lubricant storing part in the driving mechanism, and a pressure-applying means that makes the air pressure in a space provided between the two seal members, higher than the pressure of the outside air.

A manipulator includes an arm, a plurality of servo motors, a plurality of servo amplifiers, and at least one bellows container. The arm includes a plurality of joints and links. The plurality of the servo motors are disposed in a first space in the arm and capable of driving each of the plurality of the joints. The plurality of the servo amplifiers are disposed in the first space and each of the plurality of the servo amplifiers controls each of the plurality of the servo motors. The at least one bellows container with one closed end which is positioned away from the arm and another open end includes a second space which is connected to the first space at the open end. In the manipulator, each of the first space and the second space is filled with oil, and each of the plurality of the servo amplifiers is connected with a cable for serial communication or power-line carrier communication.
