  • Patent number: 6655903
    Abstract: The invention considerably reduces the danger of deformation for containers made from a thermoplastic material during the transfer to a stacking magazine or into a locally fixed catch plate. This deformation danger results from the fact that the formed stack must be displaced within a short time by the stack distance, either through the transferred containers themselves or by components of a catch plate that is moved forward with each cycle. This is achieved through displacing the stacks in the stacking magazines or the locally fixed catch plate with a displacement device. The displacement device can be combined with the stack removal device or can be a separate displacement device. According to a modification of the invention, the method is intended to improve the cooling of the stacked containers.

  • Publication number: 20030021668
    Abstract: An apparatus and method for discharging sheets from a starwheel assembly and creating stacks of a desired number of sheets without interrupting the rotation of the starwheel assembly. The present invention separates sheets such that one separated sheet completes a stack and the other separated sheet is supported by a separator to begin a new stack. The completed stack is preferably transported away from the starwheel assembly by a conveyor as the new stack supports additional sheets that are discharged from the starwheel assembly. The new stack will preferably move away from the starwheel assembly to provide clearance for the accumulation of additionally discharged sheets. The apparatus can allow for cyclical repetition of the separation of sheets, the stacking of sheets, and the transportation of stacks such that continual rotation of the starwheel assembly is not interrupted.

  • Patent number: 5971590
    Abstract: In a method for manipulating paper roll heads by a multi-axis robot (8), heads are picked-up and transferred by the robot (8) from multiple stacks in accordance with stored data concerning the height and position of each stack as well as the dimension characteristics of the articles in the stack. At initial start-up, or immediately after a shut-down, previously stored information on the position or height of the stacks is considered not known by or otherwise unreliable by the robot (8) controller. That is, when the operation of the robot (8) is halted to accommodate replacement or replenishment of the head stacks, the stored parameter data for all stacks is set unknown. In accordance with its operating program, the system operation is restarted, the robot performs a slow-speed approach toward an uncalibrated stack, measures the stack data, that is, calibrates the stack height and position, and thus can perform the next stack approach through a normal transfer cycle on the basis of the measured data.

The method comprises lifting an item to a position above a stacking position, securing the item in its lifted position, delivering a succeeding item into a position beneath the lifted item, lifting the succeeding item to a position immediately beneath the lifted item, releasing the secured item to drop onto the succeeding item, lifting the item and succeeding item together, and repeating the steps until reaching a desired stacking height.

  • Patent number: 5924840
    Abstract: Machine and method for extracting the contents from envelopes for presentation to an operator. The envelopes are stacked at an input station and fed one at a time from the input station to a cutting station. At the cutting station, the envelopes are severed along their edge portions to provide access to the contents. From the cutting station, the envelopes are transported to a separating station, where the contents are separated from the envelopes. The contents from one envelope at a time are conveyed to a pick-up station for presentation to an operator at a work station. When the operator removes the contents of one envelope from the pick-up station, the contents of another envelope are conveyed to that station and presented to the operator. As each envelope leaves the separating station, it is checked to verify that the contents have been removed.

  • Patent number: 5842827
    Abstract: A method and apparatus for stacking newspapers is disclosed which obviates the need to fasten individual stacks. Once ejected from a stacking device, stacks of newspapers pass through an assembly station where they are arranged into groups of three, called slugs, and compressed. The slug then enters a collector where a layer consisting of four slugs is positioned on a sliding table. This positioning requires lateral movement of slugs. Lateral support is provided throughout this movement to prevent the stacks from toppling over. Once a full layer has been accumulated, the sliding table is retracted, and the layer of newspapers falls onto a floating table below. This floating table, which serves as the bottom floor of the container in which it is housed, is automatically lowered by discrete amounts as layers are received. Extendible cylinders located below the collector vertically move the floating table.

  • Patent number: 5810550
    Abstract: Manufactured products, for example those produced by a die press, may be cleaned, separated, randomized and stacked with the apparatus of the present invention. A first conveyor system removes contaminants from the products. A second conveyor system separates and randomizes the products, for example, by allowing the products to cascade down an inclined conveyor belt. The conveyor is segmented to capture a portion of the products as they are pulled downward by gravitational forces. The products are aligned on a shaker table with any of several operator stations. In one embodiment the products pass through a funneling array, a slot and into a stacking tube from which operators may remove stacks of the product in preparation for shipping.
