Abstract
Abstract An automatic industrial robot is provided with an autoadaptive tactile device connected to a tool for performing at least one operation upon a workpiece. The tool is carried by a working head including a toolholder, and control means for effecting relative movement between the workpiece supporting means and the working head so as to bring a tool in the toolholder into a predetermined position relative to the workpiece subject to a certain tolerance. The toolholder is connected to the working head by a coupling which can be selectively freed to allow limited shifting of the toolholder relative to the working head and clamped so as to clamp the toolholder relative to the working head.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
251 words
In an autoadaptive working center for programmable automation having at least one operating head for performing work on a workpiece, servomotor means for moving said operating head along a predetermined path in at least two coordinates, a central processing unit comprising a program unit for storing the working center program and a processing unit for executing the working center program, said program unit additionally storing position data for defining the path of said operating head and process data for defining the operations to be performed by said operating head at predetermined points along the path of said operating head, and a control unit responsive to the position and process data in said program unit for controlling the operation of said servomotor means, wherein the improvement comprises: a plurality of transducers mounted on said operating head for sensing abnormal operating conditions at said operating head different than the operating conditions anticipated by the working center program and generating signals representative of these abnormal operating conditions; and transmitting means connected to said plurality of transducers for transmitting the signals representative of abnormal operating conditions to said central processing unit, wherein said processing unit further comprises addressing means connected to said transmitting means for generating addresses corresponding to the signals representative of abnormal operating conditions, said addressing means being connected to said program unit for addressing rescue subroutines stored in said program unit corresponding to the different abnormal operating conditions to enable said processing unit to execute a rescue operation on said operating head.
Claim 2
Dependent Claim
251 words
In an autoadaptive working center for programmable automation having at least one operating head for performing work on a workpiece, servomotor means for moving said operating head along a predetermined path in at least two coordinates, a central processing unit comprising a program unit for storing the working center program and a processing unit for executing the working center program, said program unit additionally storing position data for defining the path of said operating head and process data for defining the operations to be performed by said operating head at predetermined points along the path of said operating head, and a control unit responsive to the position and process data in said program unit for controlling the operation of said servomotor means, wherein the improvement comprises: a plurality of transducers mounted on said operating head for sensing abnormal operating conditions at said operating head different than the operating conditions anticipated by the working center program and generating signals representative of these abnormal operating conditions; and transmitting means connected to said plurality of transducers for transmitting the signals representative of abnormal operating conditions to said central processing unit, wherein said processing unit further comprises addressing means connected to said transmitting means for generating addresses corresponding to the signals representative of abnormal operating conditions, said addressing means being connected to said program unit for addressing rescue subroutines stored in said program unit corresponding to the different abnormal operating conditions to enable said processing unit to execute a rescue operation on said operating head.
Claim 3
Dependent Claim
76 words
A working center according to claim 1 wherein said servomotor means comprises a plurality of stepping motors associated with different coordinates for moving said operating head along a predetermined path in response to a number of position pulses supplied by said control unit proportional to the desired movement in each of the different coordinates, said control unit including pulse generating means responsive to the position data provided by said program unit for generating the position pulses.
Claim 4
Dependent Claim
126 words
A working center according to claim 2 further comprising: manual control means connected to said control unit and said stepping motors on said operating head for inactivating said control unit to manually control the movement of said operating head; signalling means associated with said stepping motors for supplying signals representative of the manual operation of said stepping motors to said processing unit, wherein said processing unit further comprises position data generating means for generating position data from the signals representative of the manual operation of said stepping motors; and a recording unit connected to said processing unit for recording the position data generated by said position data generating means, said recording unit being connected to said program unit for supplying position data to said program unit.
Claim 5
Dependent Claim
70 words
A working center according to claim 1 further comprising a plurality of operating heads each controlled by a different control and program units, each of said program units storing position and duration of operation data for each of said operating heads, wherein said processing unit further comprises coordinating means responsive to the position and duration of operation data in said program units for coordinating the operation of said control units.
