An apparatus and a method for detecting indicia on articles. The indicia act to identify a group of articles, having a common characteristic. The articles may be address panels used in mass mailings. Particular address panels, representing the beginning or end of a zip code or a postal delivery route, are pre-marked with one or more special indicia. The apparatus includes a scanning station, a computerized system controller, and a marking station. The scanning station includes a video camera, a video analyzer, a camera controller, and a video monitor. The video camera is programmable by using the camera controller and the video monitor, to scan only a predetermined operative scanning area of each article. The video analyzer assess each pixel within the scanning area and adds up the total number of pixels having a desired characteristic. If the pixel count satisfies predetermined criteria correlating to the presence of an indicia, the article is electronically tagged by the system controller. Then, the article is inserted into a container. In response to an electronic marking signal from the system controller, the container is physically marked at the marking station, for subsequent identification of the group.

In a mail inserter machine including at least one subassembly with a component driven in reciprocating fashion, an apparatus for inserting a sheet into an envelope. The apparatus comprises a movable gripper jaw assembly, an envelope vacuum cup assembly, an envelope opener assembly including a nozzle in communication with a gaseous fluid supply source, and an insertion assembly. An electrical control circuit is adapted to issue electrical control signals to the respective assemblies, in such manner that the occurrence and duration of the control signals determine relative periods of operation of the assemblies during a cycle of operation of the apparatus and over a range of speeds of the apparatus.

In a mail inserter having a 360 degree operational cycle and a plurality of subassemblies, a computer issues a plurality of electrical control signals having predetermined rotational positions and durations within the operational cycle at a given inserter speed. Solenoids, actuators and other driving devices are responsive to the control signals to determine the operation of the subassemblies. A device measures the operation speed of the inserter, and the computer adjusts the rotational position of each control signal within the operational cycle according to the inserter speed.

Computer controlled apparatus and method for inserting mail into

An apparatus and method for computerized control of a 'Phillipsburg-type' mail insertion machine. The mechanical timing and drive mechanisms of the prior art inserter are replaced with a programmable computer, solenoid valves, and pneumatic cylinders, or other suitable drivers. The computer's software includes a plurality of programmed look-up tables. An operational delay look-up table includes electro-mechanical lag times for the pneumatically driven stations/sub-assemblies of the inserter. Also provided are look-up speed tables, which include start and stop angles for actuation of each of the pneumatic cylinders. A first look-up speed table includes actuation data appropriate for operation of the machine within a relatively slow range of speeds. Four additional look-up speed tables provide correct actuation data for successively higher speed groups, up to 10,000 insertion cycles per hour. An alternative method of determining actuation data is disclosed, requiring ongoing and updated calculations of appropriate values based precisely upon the machine's actual operational speed.

A method of producing at least one control signal data look-up table for a mail insertion machine having a 360 degree cycle of operation and capable of variable operating speeds within a given cycle. The mail insertion machine possesses predetermined electro-mechanical lag times for extending and retracting mechanical components. The method entails creating a baseline control signal data look-up table for a first operating speed based upon pre-determined electro-mechanical lag times. The look-up table comprises a start angle and a stop angle within the 360 degree cycle of operation. The start and stop angles are then compensated for a second operating speed based upon the pre-determined electro-mechanical lag times for extending and retracting mechanical components and the first operating speed. A second control signal data look-up table is then created by writing the compensated start and stop angles that correspond to the second operating speed into the second control signal data look-up table. Look-up table data is stored in computer memory. Additional control signal data look-up tables can be instantaneously created upon selection of a different desired operating speed.

An apparatus and method for singulating sheets from a stack of sheets and transporting individual ones of them to a conveyor. A picker arm is mounted at its upper end to a rotatable shaft, for reciprocating movement between first and second positions. A lower end of the arm includes a foot and a movable gripper jaw. When the arm is rotated into the first position, it grasps a segregated sheet. As the arm reverses direction and rotates toward the second position, it draws the sheet away from the stack. A sensor, provided within the foot, produces an electrical signal corresponding to the thickness of the sheet. The digital output signal is compared to a reference, or calibration value stored in a computer. If the output signal falls unacceptably outside the reference value, a signal is stored to effect later outsorting. Just before the arm reaches the second position, the jaw is opened, dropping the sheet upon the conveyor. The conveyor is successively indexed to other picking arm stations, collating sheets for subsequent insertion into an envelope. The computer effects a downstream outsort of any envelopes containing a defective load.

An interfacing device for collating from a printer and transferring to post-printer receiving equipment, as a document packet, a complete designated document having one or more printed document pages is disclosed. The device comprises a collating tray positioned to accept from the printer each document page, a solenoid initiated system for transferring the document packet from the collating tray to post-printer receiving equipment, and an electronic information control system for tracking documents and informing the solenoid initiated transferring system that the complete designated document is printed and within the collating tray ready for transferring to the post-printer receiving equipment.
