A method for loading a sling having a bottom and sidewalls comprises placing the sling bottom on a raised platform and rolling the sidewalls down into a gutter surrounding the raised platform so that the sidewalls form a negative angle with the sling bottom. Bagged product is then loaded onto the bottom of the sling to form a stack. The sling sidewalls are then rolled up the sidewalls up the stack sides so that the sidewalls form a positive angle with the sling bottom and the sling now encloses the stack of product. The sling jig assembly includes a raised central platform on which is adapted to rest the bottom of the sling. A gutter formed about the periphery of the central platform is adapted to receive the rolled-down sidewalls of the sling.

A modular split palletizer for loading layers of articles on stackable pallets. The palletizer has a frame supporting first, second, and third sections. The first section includes a layer build area and a first portion of a stacker transfer track. The second section includes a tier sheet bin, a top frame bin, and a second portion of the track. The third section includes a pallet build area and a third portion of the track. Each of the first, second, and third sections can be disassembled, moved individually and independently, and re-assembled at a new location to form the complete palletizer. Also disclosed is a method of relocating the modular split palletizer. With the palletizer at one location, the utilities connected to the palletizer are disconnected, the fasteners holding the sections together are released, and the sections are separated. The disassembled sections are moved to the new location and reassembled.

A rotary vacuum wicketting arrangement has a rotary hub body positioned on a shaft or spindle and supporting a number of pickup arms, and a non-rotating vacuum spinning head that provides vacuum to the rotating hub body and pickup arms over a portion of their arcuate travel. The rotary hub body is provided with a lock ring formed or a pair of half rings with hand levers so that the position of the hub body on the shaft can be adjusted toollessly. The pickup arms are held in place in their sockets by ball and spring detents, so that they can be pulled out for cleaning and reinserted without tools. A friction fitted plug closes off the end of each arm.

A bale accumulator and method in which a plurality of hay bales can be accumulated and arranged into a cluster of ten bales (a “ten stack”). The accumulator first collects a bale in each of two angled bale receivers at the rear of the accumulator. These remain in position as four columns having two bales each are collected in a more forward collection. The result is two angled bales being dragged to the rear of a conventional “eight stack.” As the device releases all ten bales, gate mechanisms rotate the two rear bales 90 degrees so that they lie transverse to the eight bales comprising the “eight stack.” The two rear bales are pressed against the rear of the eight stack in order to form a ten stack.

A new type of pallet stacking assembly line. Two pick-and-place robots are used. The first robot has a relatively low position. The second robot is in an elevated position. A pallet dispenser dispenses a first pallet onto a pallet conveyor. The pallet conveyor then moves the first pallet to a first build position in front of the first robot. The first robot then begins picking products from a first pick position and stacking them on the first pallet. Once the products on the first pallet reach approximately half the finished height, the pallet conveyor carries the first pallet over to a second build position in front of the second robot. At the same time, the pallet dispenser dispenses a second pallet which is carried to the first build position. The second robot picks products from a second pick position and places them on the upper portion of the first pallet in order to complete the stack. Meanwhile, the first robot is picking and placing products on the lower portion of the second pallet. The process continues indexing, with both robots ideally being busy all the time. Each robot only has to build half the pallet. Thus, overall line speed is increased.

A bundle gripper for a palletizing machine for picking up respectively at least one bundle and depositing the bundle on a pallet. The bundle gripper including a frame, an adjustable end stop, and at least one gripper finger such that the gripper finger has a front end and is adjustable on the frame. The gripper finger being movable between a first position and a second position. The bundle gripper also including a hold-down clamp coupled to the frame and positioned against the end stop for clamping the bundle against the gripper finger such that a distance between the end stop and the front end of the gripper finger in the second position is changeable to adapt to different lengths of the bundles. The end stop and the gripper finger are each movable to change the distance and the hold-down clamp is correspondingly adjustable to accommodate different lengths of the bundles.

A method for stacking firewood which comprises the steps of supplying an elongated strap, securing a first end portion of the strap about a piece of firewood, laying a first portion of the strap along a substrate, placing a plurality of logs in a side by side relationship to form a first row on top of the first portion of the strap, wrapping the strap about an end of the first row and then extending the strap on top of the first row, stacking further objects in a second row on top of the strap and first row, and wrapping the strap about a second end of the second row and again extending the strap on top of the second row. The steps are repeated until the desired amount of firewood is stacked.

A grabber for automatically grabbing and placing packing units of different dimensions and configurations includes a frame with a support, a hold-down device and a stripper attached to the frame. The support supports a bottom portion of a respective packing unit, and is generally horizontally movable with respect to the frame. The hold-down device is downwardly movable toward the support to clamp the respective packing unit between the support and the hold-down device. The stripper is disposed above the support and is generally horizontally movable. The respective packing unit is substantially immobilized by the hold-down device and the stripper as the support is retracted.

A unit for forming packs of products for a packaging machine comprises at least three feed surfaces (3, 4, 5) for layers of products (2) and a receiving station (6) for the layers of products (2). The receiving station (6) comprises an elevator (7), mobile only between a position for loading the products (2) and a position for releasing the products (2), to transfer the layers of products (2) to a packaging machine (8). The three feed surfaces (3, 4, 5) comprise synchronization means so that they simultaneously release the respective layers of products (2) onto the elevator (7).
摘要:
A rotary die cut stacking system for use with a rotary die cutter having a rotary die configured to output die-cut sheets of material, the system including a stacker and a layboy for carrying die-cut sheets of material in a first direction from the die cutter to the stacker, wherein, the layboy has upper arms and lower arms defining a nip region therebetween for receiving the die-cut sheets, at least some of the upper arms and at least some of the lower arms being moveable transversely to the first direction, the layboy including at least one optical beam generator configured to direct an optical beam against a portion of the rotary die cutter so that a position of the arms relative to the rotary die can be determined based on the location of the optical beam on the portion of the rotary die cutter.
