Abstract: This invention pertains to load forming systems, especially those designed to place cased product on e.g. a pallet. The invention contemplates receiving cases at a high rate of input, and fragmenting the input, sending it to parallel processing elements of the load forming system. A layer creating subsystem has parallel processing elements, and preferably has sufficient designed throughput capacity to continue processing cases at the overall rated capacity of the case loading system when any one of the parallel processing elements in the layer creating subsystem fails. The case loading subsystem also can incoroporate parallel layer transfer elements and load forming elements.

Abstract: Palletizers and methods of palletizing are disclosed. The palletizers are adapted to receive and arrange units of material and to concurrently fabricate first and second layers therefrom; or to place them in layers at either of first and second delivery support areas; or both. A plurality of layer forming stations can be vertically spaced, horizontally spaced, or both. Plural load forming stations can be horizontally spaced, vertically spaced, or both. Pallets can be sequenced into the load forming stations when empty or partially empty; and can be sequenced out of the load forming stations when empty, partially empty, or full. A given layer may be a hybrid layer comprised of the sum of partial layers fabricated separately. In some embodiments, the transfer apparatus can transfer layers to more than one of more than one load forming stations.

Abstract: This invention pertains to removing a row or layer of material from a supporting surface, with the row or layer advancing on a removal conveyor in a line abreast, and converting the row or layer into a line, advancing single file. Apparatus and methods are disclosed. Each unit of material is moved in turn, longitudinally out of its line abreast, and into sole occupation of a discrete length of the converting conveyor assembly. The units so moved longitudinally are moved, as necessary, transversely across the accelerating conveyor and into an alignment zone, and are then assembled into a line advancing single file.

Abstract: This invention is a novel load forming system, including a layer forming station, a load forming station, and a transfer vehicle for transferring to a load forming station, a layer at a time, units of material which have been formed into layers at a layer forming station. The transfer vehicle, including transfer plate and support frame, is mounted on underlying support wheels, which are preferably mounted on an underlying track whose length is generally confined within the load forming system.

Abstract: Material handling equipment includes an in-feed conveyor having a sweep arm for traversing across the in-feed conveyor to thus sweep off the conveyor units of material disposed thereon. The sweep arm includes a brush, having bristles extending downwardly into spaces between the carrying elements of the conveyor, whereby thin-section materials on the conveyor are engaged by the bristles and swept off the conveyor. The sweep arm can optionally also sweep the materials onto and across the in-feed station of a palletizer positioned adjacent the in-feed conveyor. The in-feed station can have channels in its upper surface, extending in the direction of sweep of the sweep arm.

Abstract: Palletizing apparatus of the invention comprises a load forming station, a device for placing a layer on a pallet, devices for forming and placing a cap on the layer, and devices for applying restraint to formed edge panels of the cap. A formable cap sheet is received into the palletizing system as a flat sheet, and leaves the palletizing system as a formed cap on a load layer. The resulting pallet loads are preferably stretch wrapped. Methods of operating the apparatus are also disclosed.

Abstract: A novel spacing sheet is used in place of a conventional tie sheet in layered material loads, such as pallet loads. The spacing sheet generally comprises a plurality of spaced apart surface elements and intervening channels, on its top surface, which generally facilitate handling of the material on the sheet. The channels especially facilitate removal of material from the spacing sheet. The spacing sheets are generally thicker than a conventional paper tie sheet while being thinner than a conventional pallet.

Abstract: This invention pertains to handling of material on a supporting surface, preferably a pallet (74). It is addressed especially to the handling of material in pallet loads. The invention provides material handling systems and methods for placing material on a supporting surface by a palletizer (10) and removing it from that supporting surface by a depalletizer (210); and wherein the common element necessary to make the system function resides in the use of a special spacing sheet under each layer (178) of material in the load. Supporting members include spacing sheets (161) and (166) having novel characteristics in their top and bottom surfaces, and novel tacky spacing sheets (300) which are lightly and temporarily bonded to the underlying layer or pallet.

Abstract: This invention pertains to handling of material on a supporting surface, preferably a pallet 74. It is addressed especially to the handling of thin-sectioned sheet material such as loose newspaper and magazine products in pallet loads. The invention provides material handling system and method for placing the material on a supporting surface by means of a palletizer 10 and removing it from that supporting surface by means of a depalletizer 180; and wherein the common element necessary to make the system function resides in the use of a special supporting member under each layer 178 of material in the load. Supporting members include spacing sheets 166 having novel characteristics in their top and bottom surfaces and novel pallets 216 having novel characteristics in their top surfaces.

Abstract: Material handling apparatus and methods, especially for use with loose stacks of paper and the like in pallets. The invention includes depalletizing apparatus, distributing apparatus, and hopper loading apparatus; and material handling apparatus for transporting material between the depalletizing apparatus, the distributing apparatus, and the hopper loading apparatus. The depalletizing operation includes lateral sliding of layers of a pallet load onto a removal conveyor and then away from the pallet. Significant advantages are achieved by using a special spacing sheet in the pallet load instead of slip sheets and tie sheets. Fingers on the pusher extend below individual layers of the load and into the channels in a spacing sheet, effecting the removal of even the bottom layer of papers in a stack. Similar use of fingers and channels applies to operation of the hopper loader and its control of the bottom papers in the stack.

Abstract: A palletizing apparatus usable for depositing material on an underlying surface, and particularly an underlying layer of compressible material. The apparatus comprises a frame, a plate means mounted on the frame for vertically and horizontally moving the plate means relative to the frame, the plate means including an upwardly facing surface adapted for carrying a stack of material and a downwardly facing surface having therein a plurality of recesses extending in the direction of the horizontal movement of the plate means. Projections mounted on the frame extend upwardly into the recesses for preventing a previously deposited layer of materials from moving with the plate means as the plate means is withdrawn from under the stack. The palletizer further comprises means for withdrawing the plate means from under the stack while an underlying layer of compressible material is under compression.
