  • Patent number: 11926486
    Abstract: According to an embodiment, a conveyance assisting apparatus includes a placement portion, a base portion, a support portion, a moving device, and a projecting portion. The placement portion has a placement surface on which a package is placed. The base portion is fixed to a conveyance apparatus including a door portion to be opened/closed between a closed-position and an open-position. The support portion is on the base portion and supports the placement portion so that the placement portion is movable in a first-direction between a first-position where the placement portion covers the door portion and a second-position where the placement portion uncovers the door portion. The moving device is on the base portion and configured to move the placement portion. The projecting portion is on the placement surface and extends in a second direction intersecting the first direction.

  • Patent number: 11440744
    Abstract: System and methods for estimating the number of packages in a measurement zone to gauge package flow. A linear array of distance-measuring sensors measures the height profile of a mass of packages conveyed past. The profile is differentiated, and steps in the differentiated profile are counted to detect package edges and to produce an estimate of the number of packages in the measurement zone. The estimate can be used to adjust the speed of the conveyor to provide a constant package flow.

  • Patent number: 6848568
    Abstract: A method, apparatus and software product for moving bulk materials effectively through a path gate in a distribution system provides at least two independently operable conveyors aligned in series such that the end of the first conveyor is adjacent to the beginning of the second conveyor with a pass gate positioned downstream of the two conveyors. In cases where the bulk material has formed into a cohesive block, the first conveyor is operated to bring the block near the second conveyor. Then, the first conveyor is slowed or stopped while the second conveyor is operated at a higher speed than the first conveyor. This action causes the portion of the cohesive block adjacent to the second conveyor to topple or break down, thereby breaking down the cohesiveness of the block and directing a portion of this toppled bulk material forward onto the second conveyor. Then, the second conveyor urges this portion of the bulk material toward the downstream path gate.

  • Patent number: 6812426
    Abstract: A method and apparatus for automatic spacing and diverting of packages on a conveyor system ensures an adequate gap between packages deposited onto a loading conveyor for subsequent inspection. A speed ratio between the loading conveyor and an inspection conveyor, a package detector disposed between the loading conveyor and the inspection conveyor, an interruption device controlling the loading conveyor and a controller to permit a signal from the package detector to command the interrupting device to temporarily halt the loading conveyor are used to ensure proper spacing between packages passed to a scanner. The apparatus may also include a package diverter for diverting a package to another area for further inspection.

  • Patent number: 6484066
    Abstract: An image lift tunnel scanner uses extended depth of field cameras in order to view objects of various shapes and sizes on a conveyor system. The image lift tunnel scanner operates by passing a package first through a dimensioning device, such light curtain that determines the package's height, width, length, orientation and position on the conveyor belt. A bottom scan camera takes a fixed focus image and requires only a trigger and length information from the light curtain. The length information determines the duration of the scan after the camera receives the trigger signal. A top scan camera also requires a trigger and the length information along with the height information so that it can set its focus. Each of two side cameras also receives trigger and length information. If the package is registered on the conveyor belt, the only additional information required is the package width and the package position on the conveyor belt so that the start and stop of the image scan can be calculated.

  • Patent number: 6390282
    Abstract: A conveyor system comprises pairs of vertically spaced and horizontally oriented pulleys and belts that are positioned on opposite sides of a conveyor path. The belts wrap around the pulleys and engage with opposite sides of an object being conveyed by the conveyor, for example an empty plastic blow molded bottle, and convey the object along the conveyor path between the belts. A vertical adjustment mechanism quickly adjusts the vertical positioning of the pairs of pulleys and belts on each side of the conveyor path to quickly adapt the conveyor for conveying different sized objects.

  • Patent number: 6352252
    Abstract: A conveyer device for bookbinding machines having a number of processing stations and having plate or cleated chains or the like which take over book blocks and convey them intermittently to the processing stations. The plate or cleated chains are driven in a circulating manner and have chain beams that act in opposite directions to one another. The chain beams include longitudinal bearers and longitudinal guides on which strands of the plate or cleated chains are supported. In order to shorten the set-up time, the distance of the chain beams of the plate or cleated chains from one another is varied by a setting drive via setting members for the purpose of adapting to different thicknesses of book blocks. The thickness of a particular book block is automatically determined in the setting-up operation via a measuring arrangement in the intake.

  • Patent number: 6273240
    Abstract: A control system is provided for a vibratory conveyor including a detector applicable to detect when the depth of product on the conveyor is at a determined minimum value. The product-conveying rate of the conveyor is adjusted so that the depth is maintained at or around the minimum value. This is done by logging the total time, during a given period, for which the depth of the product exceeds, or falls below, the determined minimum value, and varying the product-conveying rate depending upon whether the total time that product is detected is more or less than a given percentage of the period.

  • Patent number: 6237427
    Abstract: A flow rate measuring system for conveyed material includes a conveyor including a frame and a material supporting surface moveably supported by the frame. The flow rate measuring system utilizes height measurement devices which are responsive to the height of the material supported on the material supporting surface of the conveyor for taking material height measurements. A signal generating device provides an output signal in response to the height measurement device. The height of the material on a conveyor of known width and known speed allows the calculation of volume or mass flow rates. The height measurement device typically comprises a deflection impact surface which is a finger or paddle assembly. The flow rate measuring system for conveyed material additionally may include a signal processing device such as computer for taking and recording height measurements as specific intervals.
