Abstract: An automatic egg tray stacking apparatus turns alternate egg trays through the operation of movable guides at the junction with a loading conveyor before conveying the egg trays toward a stacking mechanism that first stops the egg tray and then lowers the stack on top of the egg tray before re-elevating the partially formed stack to permit the entrance of a new egg tray into the stacking mechanism. Once the stack of egg trays is completed, the stack is allowed to move onto a stack conveyor and is moved forwardly for shipment. The stacking mechanism is operated by a single actuator having dual pneumatic cylinders that provide a three position operation of the lifting function with the stacking mechanism having lifter members engaging all four sides of the lowermost egg tray of the elevated stack. A control mechanism operates the apparatus with input from appropriately positioned sensors.

Abstract: The device includes a stacking surface movable in a substantially vertical direction, on which layers of products to be packaged are superposed, and a pair of conveyors substantially superposed to feed the layers of products to the stacking surface. The device also includes a pair of walls substantially parallel, and substantially vertical, between which the layers of products are inserted by the conveyors when they are stacked on the stacking surface. The walls move reciprocally towards and away from each other to take a position of greater reciprocal distance, in which they do not interfere with the products deposited on the stacking surface, and a position of lesser reciprocal distance, in which they interfere with the products inserted therebetween.
Abstract: A method and device are provided to produce stacks composed of printed products. Printed products are supplied substantially vertically and in an overlapping flow with the aid of a first conveying device continuously to an essentially horizontally extending stack support. A stack is formed at the stack support, where the printed products are at least approximately lined up in an upright position. The stack on the stack support is transported with a second conveying device moving at a forward-feed speed and in a forward-feed direction. The stack is supported along a leading stack end against a support device that also moves in the forward-feed direction. A third conveyor acts upon a region of a lower edge of at least one printed product, which impacts the stack support, to move the at least one printed product in the forward-feed direction of the stack with a speed that corresponds at least to the forward-feed speed of the stack.

Each pushing element is connected with a directing element arranged on the backing side. The directing element includes a sliding surface facing away from the conveying belt. The conveying device contains a guide rail having a guiding surface for the directing elements arranged in a partial section of the conveying belt lying between the deflection pulleys. The sliding surface and the guiding surface are of a complementary shape so that the sliding surface can slide on the guiding surface.
Abstract: An apparatus for transferring an upright tray at high speeds that can sense an entrance and discharge of the tray. The apparatus includes a transferring unit with pulleys driven by a driving source to form a transferring path. The pulleys contact a fixing member, which is attached to a lower edge of a substrate and mask fixed to the tray. The apparatus also includes a sensing unit with a sensor installed beneath the transferring path to detect the entrance and discharge of the tray. The apparatus may also include rollers disposed to contact both sides of the upper portion of the tray, and the rollers may be coupled with moveable members encased within rails along the transferring path so that the rollers can translate when a tray passes between two rollers. The rollers along both sides of the tray can be arranged symmetrically or alternately in a zigzag pattern.
Abstract: There is described a machine for forming groups of ordered products, each group including products disposed according to superposed layers. The machine includes a succession of conveyors aligned according to a principal direction of alignment, with a feed conveyor and a delivery conveyor. The feed conveyor receives single layers of products aligned with and spaced from one another; and the conveyors are disposed and controlled so as to distribute layers of products on a predetermined number of levels at different heights, and to unload onto the delivery conveyor a predetermined number of layers, superposed on one another, equal to the predetermined number of the levels at different heights.
Abstract: A stacking apparatus for a conveyor system raises a two-dimensionally arrayed layer of objects conveyed by the conveyor system and stacks the raised layer of objects on a subsequent layer of objects conveyed by the conveyor system. The apparatus then dispenses the stacked layers of objects from the apparatus, whereby the stacked layers of objects can be received by a palletizer for loading on a pallet in a more time efficient manner.

Abstract: A movement and distribution assembly, particularly for products to be packaged, comprising elements for moving products to be wrapped by means of a film, along a feed line of an apparatus that is functionally associated with a dispenser of the film for wrapping the products. At least the end portion of the feed line is constituted by at least two end parts that are substantially functionally parallel and lead to respective compartments of the apparatus for providing the final configuration of the wrapping of the products. Each of the end parts comprises at least one launcher for organizing the flow of products according to preset sequences, on each of the end parts.
Abstract: A system for bundling long ferrous products comprises a roller table for delivering the products longitudinally to a receiving station. A cradle is spaced laterally from the receiving station and is constructed and arranged to receive and accumulate the products in bundle form. A stacker is positioned between the receiving station and the cradle, and a pre-stacker is positioned between the stacker and the receiving station. A transport system laterally advances products from the receiving station to the pre-stacker, and the pre-stacker operates in concert with the transport system to pre-stack multiple layers of the products into sub-bundles and to transfer the sub-bundles to the stacker, which then operates to deposit the sub-bundles in the cradle.
Abstract: In a station for forming a pile of layers of items, a surface receives layers of items to be transferred to a first support plane situated after the receiving surface. The items arranged in layers are moved along the receiving surfaces and the first support plane by driving chains connected by rods set crosswise to the receiving surface and support plane. The support plane is spaced apart from the receiving surface to define a window and a descending ramp is situated below the window. An additional conveyor formed by narrow slats or rolls, is situated at the window and is operated so that one flexible plate moves to cover and uncover the window, so that layers of items are alternately either carried from the receiving surface to the support plane or made to pass through the window and released on the descending ramp. The ramp can change inclination so as to connect the receiving surface to either one or the other of second and third support planes situated below the first support plane.
Abstract: In a station for forming stacks of layers of articles, a horizontal supporting surface has a window for allowing a layer to pass freely therethrough. First pushing bars drive the layers along the support surface. A stationary descending ramp starts from the initial part of the window and extends downstream. A horizontal lower surface is situated after the ramp and under a horizontal upper surface, and forms a part of the support surface situated downstream of the window. An additional conveyor is associated to the window to restore cyclically a continuity in the support surface in the region of the window for the odd layers, and consequently to direct each odd layer toward the upper surface, and to allow the even layers to pass cyclically through the window. The even layers are consequently directed, due to gravity, onto the ramp. Second pushing bars move each even layer to the ramp and convey the even layer to the lower surface.
Abstract: A letters/flats transporting, handling, and sorting system is disclosed for handling an initially random mixed input of letters and flats and for sorting the letters and flats into a delivery address sequence for delivery by postal service personnel as a result of only a single pass of the letters and flats through the system. Sequencing modules include loading trays and storage trays. The storage trays represent individual delivery address destinations and are arranged in delivery address sequence. Incoming letter and flat mail is deposited within the loading trays and the loading trays are individually actuated so as to transfer the letter and flat mail pieces into the proper delivery address storage trays whereupon the completion of the processing of an entire batch of incoming mail, all mail will be sorted in delivery address sequence within the storage trays which may then be emptied for ultimate delivery in their address sequence by the postal service personnel.
Abstract: Cigarettes are formed into groups by a device comprising a hopper through which to direct a flow of cigarettes, a conveyor with pockets moving intermittently past a discharge outlet of the hopper, and a reciprocating pusher located on the side of the hopper opposite from the conveyor by which a portion of the flow corresponding to one group is directed with each forward stroke into a respective pocket. To avoid damage of the kind often associated with sliding contact and axial compression, the cigarettes adjacent to those ejected by the pusher are restrained when their cylindrical surfaces are attracted by suction generated through ports located inside the hopper.
Abstract: An article retention apparatus includes a roller conveyor unit with a plurality of rollers arranged in a horizontal plane and a plurality of ladder-shaped rack units on which articles rest. The roller conveyor unit and rack units are configured such that the rack units may be moved above and below the plane of the conveyor unit rollers without interference between the conveyor unit rollers and the rack units. By lifting the rack units one by one from below the roller plane to emerge above the roller plane, the article is transferred from the roller conveyor unit to the rack unit. The articles are taken aside of a transport system and temporarily retained by the apparatus. A belt conveyor unit can be used instead of the roller conveyor unit.
