  • Patent number: 7002135
    Abstract: Printed products are accurately detected, counted and tracked as they move from a gripper conveyor to a lay down conveyor. The printed products are further tracked from a position where they reach a sensor upstream of the stacker where the position of selected printed products is provided to the stacker, together with a flag for those selected printed products, to assure that all of the stacker operations, including product stream interception, turntable rotation and bundle ejection, are performed with precision. Counting and tracking are performed by different sensors upstream relative to the stacker and the tracking function is transferred to the stacker when a flagged signature reaches a nip of the stacker infeed. Counting of printed products by the stacker is eliminated.

  • Patent number: 6876716
    Abstract: Printed products, such as newspapers are fed past a counting station arranged in imbricated fashion, preferably folded edges passing downstream first. A high intensity light source is arranged so that its light beams are oriented at an angle which, while illuminating upper surfaces of the newspapers, causes the forward folded edges to cast a shadow upon the upper surface of a downstream newspaper that the forward edge of the newspaper creating the shadow rests upon. An image sensing device creates an image of a given region which includes the leading edge of the newspaper creating the shadow. This image is compared with stored criteria to determine if the “shadow” is due to a leading edge of a newspaper and to thereby discriminate a newspaper leading edge from other spurious conditions which, although they may create a “shadow”, fail to meet the criteria of a leading edge of a newspaper.

  • Patent number: 6086308
    Abstract: Wheeled carts are pushed onto an inlet end of a conveyor and are automatically advanced, one at a time, to a cross conveyor for delivery to a cart loader conveyor. A cart loader is provided near the outlet end of the cart loader conveyor for automatically loading bundles into a wheeled cart. The input conveyor advances wheeled carts one cart position at a time. Cart positions along the input conveyor are monitored by sensors to automatically control advancement of wheeled carts therealong. A cart delivered from the outlet end of the input conveyor to the cross conveyor activates a cross conveyor limit switch advancing the cart delivered thereto to a position for feeding a wheeled cart onto the cart loader conveyor. A limit switch is actuated when the wheeled cart reaches this position where upon a push bar pushes the cart activating the limit switch onto the cart loader conveyor. The conveyor system in cart handling are preferably operated by hydraulic devices due to their compactness.

  • Patent number: 5930975
    Abstract: Bottom wrap/three-quarter wrap apparatus having an automatic web feeder for safely advancing a web fed from a supply roll to a main web feeder. The main feed rollers advance one length of the web and a cutter cuts the advanced length, completing one cycle of operation, after which the bottom wrap/three-quarter wrap apparatus is placed under control of a bundle feeder. The main feed roller pair are displaced from one another when the web passes between creasing rollers. When a predetermined length of web has been advanced to the creasing rollers a cutter cylinder moves a blade mounting plate in the cutting direction. A resilient clamping assembly arranged on the mounting plate momentarily clamps the web between the mounting plate and a web guide just prior to severing of the web by the blade, maintaining the web taut during cutting. The cutting blade is rapidly moved back to a position displaced from the web in preparation for a subsequent cutting operation.

  • Patent number: 5772391
    Abstract: Signatures are delivered to a stacker by a gripper conveyor, each gripper delivering a signature thereto. The grippers follow a curved path adjacent to the stacker, substantially aligning the signatures with the stacking platform receiving signatures as they are released. A plurality of stacking platforms are moved about a closed loop path, each independently driven by an associated drive motor. The speed of each stacking platform is variable and is synchronized with the throughput of the gripper conveyor as well as signature thickness. When a predetermined quantity of signatures has been collected, an upstream stacking platform is moved between the last signature of the preceding stack and the first signature of the next stack. When a stack has been completed, the stacking platform is quickly pulled away from the signature stack allowing it to fall by gravity into a collector, and is thereafter moved quickly to the ready position in preparation for forming a subsequent signature stack.

  • Patent number: 5274983
    Abstract: Method and apparatus for wrapping a signature bundle by moving a wrapping sheet into the path of movement of a bundle, said sheet being maintained in self-supporting fashion by imparting a bend thereto as it is fed to the wrapping station. The bundle "crashes" into the sheet causing it to collapse and wrap itself about the bundle. When the wrapping operation is completed, the wrapping sheet is wrapped around three contiguous surfaces of the bundle. The sheet is automatically cut and a new wrapping operation is initiated. The wrapping sheet may be printed upon by an ink jet printing characters "on the fly". The characters are printed backwards and "bleed through" the wrapping sheet to appear in normal manner.

  • Patent number: 5226780
    Abstract: A dual drive signature stacker having side-by-side stacker sections, each of substantially identical design and including a stepper motor for driving a pair of buckets for receiving signatures secured at spaced intervals along a drive chain driven by the stepper motor. The buckets have intercept blades supported by brackets joined to the drive chain to position one of the intercept blades of each drive assembly in front of the adjacent drive assembly so that all of the buckets of the dual drive assembly are in alignment with one another and with the signature stream. The side-by-side arrangement greatly simplifies the design cost and assembly. A microprocessor-based control system permits stacking of stacks having as few as two signatures and is further capable of forming successive signature stacks of differing count in a precision manner and compatible with the speeds of any signature flow rate.

  • Patent number: 5181820
    Abstract: In an automatic loading system and method wheeled carts receive five or six layers of newspaper bundles of four to six bundles per layer. A waist-high conveyor and an inclined ramp conveyor move bundles to a roller platform of independently operated roller sections selectively halted upon receipt of a bundle. When the desired number of bundles have been delivered to the roller platform, a pusher laterally moves the bundles to a split roller platform. A second group of bundles are delivered to the roller platform and the split roller platform. The sections of the split roller platform are then abruptly pulled apart causing the bundles to drop upon a fork-like platform extending into one side of a cart receiving the bundles. The pusher is retracted to the start position and the fork-like platform is lowered to receive the next layer of bundles in a like manner.

  • Patent number: 5135102
    Abstract: A bundle distribution system is comprised of tilt tray carriers coupled in tandem forming a continuous loop, each carrier being a link in the loop. A top loader which is positioned above the track so as to minimize the space required therefor, is capable of dropping signature bundles onto the desired tray with great accuracy. The top loader also orients bundles delivered thereto at an angle which compensates for tilting of the bundle as it leaves the top loader thereby assuring that bundles are dropped upon each carrier in a predetermined orientation, without tumbling.
