摘要： An apparatus for limiting range of motion of an industrial robot in accordance with the invention includes an indicating section (7) for indicating e.g. angles of rotation provided on a stationary side (1) of the swivel portion of an axis about which swiveling motion is possible. A range limiting member (6) having a dog and a stopper is movably disposed on the indicating section (7). When the industrial robot attempts to rotate beyond a stipulated range of rotation during operation, a limit member (81) provided on a movable side (2) of the axis portion contacts the dog (61) on the stationary side (1) to detect overtravel, whereby a warning is issued to the effect that the stipulated range of rotation has been exceeded. When the robot attempts to rotate further due to inertia, a shock absorber (82) strikes a stopper mechanism (62) to prevent excessive rotation.

摘要： An apparatus for setting an industrial robot at the standard position comprises a block (19) to be measured, which is attached to a top end portion (18) of a wrist of the industrial robot, and a supporting member (23) for the measurement, which is attached to a fixing base (11) of the industrial robot. The block has three planes (20, 21, 22), orthogonal to one another, to be measured, and the block is positioned to the top end portion of the wrist so that the three planes to be measured are set at predetermined positions relative to the top end portion of the wrist. The supporting member has three frames (24, 25, 26) orthogonal to one another, and the supporting member is positioned relative to the fixing base so that the three frames take predetermined positions relative to three-axis orthogonal coordinates predetermined on the basis of the fixing base. By a plurality of dial gauges (27 through 32; 37 through 42), the positions of the planes of the block are measured. The dial gauges display predetermined values only when the planes to be measured of the block are set at predetermined positions relative to the frames of the supporting member.

摘要： The industrial robot comprises a lower arm (13) provided on a robot body (12) pivotably about a first horizontal axis (C1). The lower arm (13) has provided thereon a forearm (14) pivotably about a second horizontal axis (C2). The forearm (14) is rotationally driven by a drive such as a motor (16). The robot body (12) has provided thereon a rotating disk (17) interlocked with the pivoting of the forearm (14) about the second axis (C2) and rotatable about the first axis (C1). Also the rotating disk (17) has secured thereon a first wheel (18) and coaxial therewith, the diameter of which is smaller than that of the disk. There is further provided a tension spring assembly (19) having one end thereof connected to the robot body (12) and which has rotatably mounted at the other end thereof a second wheel (21) having nearly the same diameter as that of the first wheel. Also provided is a chain (22) having one end thereof connected to the rotating disk (17) and the other end engaged on the first wheel (18). This chain (22) is engaged on the outer circumference of the second wheel (21) while pulling the tension spring assembly (19). The one end of the chain (22) is so disposed on the rotating disk (17) that when the upper end of the forearm (14) is directed normally downward, the chain portion (22b) between the rotating disk (17) and the second wheel (21) is substantially parallel to the chain portion (22c) between the first and second wheels (18) and (21).

摘要： An apparatus for guiding a cable of an industrial robot having a support casing and a swivel casing axially supported by a swivel shaft bearing includes a cable guide. The guide has an end of an upper arm axially supported on a swivel axis inside the swivel casing, and an end of a lower arm axially supported on the swivel axis inside the support casing. A back column formed between the upper and lower arms guide passes through first and second arcuate cut-out portions provided in the swivel casing and support casing. A cable is passed from the support casing into the swivel casing along the cable guide back column, and moves proportionately to angular movement of the swivel casing.

摘要： An industrial robot is able to automatically set the operating conditions thereof depending on a position of installation. The motion of a robot unit is input and controlled by a robot control unit. A first data storage portion of the robot control unit is provided with a storage region preliminarily storing (a) data about installation positions of the robot unit with respect to a reference installation position of the same robot unit, and (b) date about operating conditions with respect to the positions of installation. When data about an installation position upon the use of the robot is input to the robot control unit, the data of the operating conditions, in response to the input data of the position of installation, is read from the first data storage unit, and is automatically set in a second data storage unit to control the motion of the robot unit in accordance with the operating conditions set in the second data storage unit.

摘要： A sealing gun (31) of a sealant application unit, which controls the flow of the sealant in accordance with the value of an input signal, is attached to the end of a robot arm. The value of a signal applied to the sealant application unit (30) is controlled in association with acceleration/deceleration control of the moving speed of the sealing gun. The moving speed (TSA) of the sealing gun and the flow (SC) of the sealant discharged from the sealing gun are in direct proportion; therefore, the bead width becomes uniform independently of the moving speed (TSA) of the sealing gun.
