Abstract
Abstract A transfer type working system including a transfer line for intermittently conveying workpieces thereon. The transfer line has plural stages of working stations disposed in front and rear relationship. Each of the working stations has at least one machine tool for working on one of the workpieces on that station. Each of the machine tools comprises a ganghead replaceable machine tool having plural gangheads arranged to be selectively operable. Each of the working stations has, at a preceding position thereof, a front sensor for reading the kind of workpiece on a preceding position so that, in the course of conveying any of the workpieces to each of the working stations, one of the gangheads that corresponds to the kind of workpiece read is previously selected for operation by a signal obtained at the front sensor.

Claim 1
Independent Claim
253 words
A transfer type working system comprising a transfer line for intermittently conveying workpieces thereon having plural stages of working stations disposed in front and rear relationship, each of the working stations having at least one machine tool for working upon one of the workpieces on that station, each of the machine tools comprising a ganghead replaceable machine tool having plural gangheads arranged to be selectively operable and each of the working stations having at a preceding position thereof with a front sensor means for reading the kind of workpiece on a preceding position so that, in the course of conveying any of the workpieces to each of the working stations, one of the gangheads that corresponds to the kind of the workpiece read is previously selected for operation by a signal at the front sensor means, a rear sensor means for reading the kind of workpiece which has been conveyed to that particular working station so that, after the correspondence between the kind of the workpiece which has been conveyed to the particular working station and the previusly selected ganghead is confirmed to be correct, the selected ganghead may be brought into a working operation, the rear sensor means being used also for the front sensor means for the next stage working station, and control means connected to the machine tool and operatively coupled to the front and the rear sensor means for selecting the appropriate ganghead, for confirming the same to be correct, and for controlling the operation of the selected ganghead.
Claim 2
Dependent Claim
253 words
A transfer type working system comprising a transfer line for intermittently conveying workpieces thereon having plural stages of working stations disposed in front and rear relationship, each of the working stations having at least one machine tool for working upon one of the workpieces on that station, each of the machine tools comprising a ganghead replaceable machine tool having plural gangheads arranged to be selectively operable and each of the working stations having at a preceding position thereof with a front sensor means for reading the kind of workpiece on a preceding position so that, in the course of conveying any of the workpieces to each of the working stations, one of the gangheads that corresponds to the kind of the workpiece read is previously selected for operation by a signal at the front sensor means, a rear sensor means for reading the kind of workpiece which has been conveyed to that particular working station so that, after the correspondence between the kind of the workpiece which has been conveyed to the particular working station and the previusly selected ganghead is confirmed to be correct, the selected ganghead may be brought into a working operation, the rear sensor means being used also for the front sensor means for the next stage working station, and control means connected to the machine tool and operatively coupled to the front and the rear sensor means for selecting the appropriate ganghead, for confirming the same to be correct, and for controlling the operation of the selected ganghead.
Claim 3
Dependent Claim
50 words
A system as claimed in claim 1 wherein the transfer line further includes, at each interval between every adjacent working station, an orientation changing station so that the workpiece at the orientation changing station may be given an orientation change during the working upon the workpieces at each working station.
Claim 4
Dependent Claim
35 words
A system as claimed in claim 1 further comprising a magazine for gangheads positioned adjacent said machine tools, a runway disposed between said magazine and said tools and means for conveying gangheads on said runway.
