A system is disclosed for assigning stitch patterns that are to be automatically sewn on workpieces presented to an automatic sewing machine. The system is capable of receiving a number of communications that identify separate stitch patterns that are to be sewn on a workpiece. The system analyzes these communications and either accepts or rejects the communications as valid stitch pattern assignments. In the event that a communication is accepted, it is stored in a recallable sequence of stitch patterns that are to be sewn on the workpiece.

Pattern assignment system

For determining a path of movement of a tool along shoe bottom marginal portions a series of points along such path is selected and information regarding such points stored in the form of digitized co-ordinate axis values by a computer, from which information the path can subsequently be derived. The selected points are spaced by a predetermined distance (which may be the same for each pair of adjacent points) regardless of shoe bottom contour. To this end, when each point is digitized, the tool and shoe bottom are relatively moved apart by the predetermined distance along a first axis, extending heightwise of the shoe bottom. Thereafter in returning the tool and shoe bottom into engagement along said one dimension under operator control, appropriate compensating movement also takes place automatically along a lengthwise axis and/or along widthwise axis. In addition, relative movement may also be effected between the tool and surface under operator control along said widthwise axis, compensating movement then automatically taking place along said lengthwise axis. In either case, the compensating movement serves to maintain the predetermined distance between the tool and the workpiece surface.

A system is disclosed for automatically processing workpieces requiring more than one stitch pattern. The system is operative to automatically select one of a number of previously assigned stitch patterns when a workpiece is presented for sewing. The automatic selection is accompanied by an incremental pointing to the next stitch pattern which is to be sewn when the workpiece is again presented for sewing.

System for processing workpieces for sewing

A sewing machine system possesses an interactive communication capability allowing for the assignment of stitch patterns with respect to workpieces to be sewn. The workpieces are arranged within pallets having binary codes impressed thereon. The stitch pattern assignments are made in conjunction with the sensing of the binary codes. The workpieces are automatically processed from a location wherein the binary codes are sensed, to a location wherein the pallets are attached to an automatic positioning system. The workpieces are furthermore processed through to an output position when the respectively assigned stitch pattern has been sewn.

A system for processing workpieces prearranged within pallets that are to be sewn by a sewing machine. The system includes apparatus for automatically processing a pallet from an input location to a location wherein the pallet can be automatically attached to a positioning system. The positioning system moves the attached pallet into position underneath the sewing machine head for subsequent sewing of a stitch pattern. The sewn workpiece is returned to a location where the pallet can be detached from the positioning system. An ejector mechanism automatically moves the detached pallet to a location which does not interfere with the automatic processing of another pallet loaded at the input location.

Sewing machine having automatic pallet handling

A computer-controlled machine for progressively roughing marginal portions of shoe bottoms comprises a tool support arm, on which two rotary roughing brushes are carried side-by-side, and a shoe support between which and the arm relative movement takes place lengthwise, widthwise and heightwise of the shoe bottom. The relative lengthwise movement is fore-and-aft, and the left hand tool is arranged to operate along the right hand side of the shoe bottom as relative movement takes place in one direction, and vice versa in the opposite direction. For effecting such relative lengthwise movement, furthermore, the shoe support is mounted for movement along an arcuate path about an axis extending transversely of the shoe bottom. Conveniently, two shoe supports are provided, arranged side-by-side, the tool support arm being aligned alternately with each shoe support.

Machine adapted for use in the manufacture of shoes

Apparatus for the combined marginal roughing and toe scouring of shoe bottoms has a shoe support movable in an arcuate path past marginal roughing tools and a scouring tool, the roughing tools being movable widthwise and heightwise of the shoe bottom, and the scouring tool heightwise. All the movements are under the control of n.c. motors. The scouring tool thus follows a pre-determined path, giving enhanced control of the degree of scouring. To assist in accuracy, the shoe support has height datum means which, after use and subsequent to toe support means being locked in adjusted position, are moved out of the way so as not to impede the roughing and scouring.

A control system for a shoe upper conforming machine, more especially a pulling over and toe lasting machine, includes a computer control which supplies control signals sequentially, according to a programmed instruction, to actuating means for the various operating elements of the machine. In particular, the release of the grippers is controlled in relation to the movement of the wiper means. Furthermore, the power supply to the actuating means for effecting gripping and pulling is independent of that for the actuating means for wiping over and securing the lasting margin to the insole, the arrangement being such that the power supply to the latter is operatively connected only after the operation of the former is completed.
