A conveyor accumulates collapsed, flexible flat tubes into roughly aligned stacks which are transferred to a collator comprising an inclined tray-like receptacle mounted for multidirectional movement. The receptacle is simultaneously rotated and pivoted from a loading station to a discharge station while being rapidly reciprocated to vibrate the roughly stacked tubes. The combined effects of gravity and vibration urge the tubes to shift relative to each other into engagement with adjacent sidewalls of the tray to align the stack. A pallet mounted for multidirectional movement at the discharge station is automatically indexed to allow the aligned stacks to be deposited at preselected locations on the pallet.

Method and apparatus for stacking and collating articles

Apparatus is described for inverting boxes of different heights in conjunction with an in-feed conveyor and an out-feed conveyor. The relative position of two conveyor segments is changed to clamp a box therebetween. The conveyor segments are then inverted and the box released to continue on the out-feed conveyor in the inverted position.

Box inverting apparatus

A device, used for clamping and rotating the object, includes two first rods, one ends of which are respectively connected to one ends of the first plate and the second plate through a linked unit; another ends of the first rods are connected to the third rod that is used for balancing the rotating angles of the first rod and two linked units, such that the heights of two ends of the first rods and the second rods can be kept in step Two second rods are connected to the first plate and the second plate respectively, as well as, another ends of second rods are connected to the fourth rod respectively Accordingly, the fourth rod can be rotated to drive the second rod, such that the first plate and the second plate can be rotated Therefore, due to two plates are used for clamping and rotating synchronously, users can take the advantages while the device is used

Device for clamping and rotating the object

An apparatus for conveying blanks or sheets that are arranged in piles includes a frame that has an input and an output and a pre-section that aligns the piles of blanks along a longitudinal conveying path. The pile of blanks is conveyed to a turn-over grip that swivels around the horizontal axis that extends transversely to the longitudinal conveying path. The turn-over grip includes two conveying units that are juxtaposed to one another with one of them being used to deliver the piles entering the turn-over grip and the other which is used to remove the piles after the turn-over grip has turned the pile upside down. A tightening mechanism presses one of the conveying units towards the other during the rotation of the turn-over grip. A pusher carriage is situated between the two conveying units and driven by a motor.

Device for turning piles of sheet-like material

An apparatus for forming bundles of elongated objects comprises a first member which individually drags the objects, and, after having appropriately oriented said objects, if necessary, about the respective axis, delivers them onto a receiving surface provided in a second member. The distance of said surface from the ground may be varied so as to allow to pile the objects, and the second member itself may be displaced transversally to the dragging direction of the objects, to allow to form adjacent piles of objects. The objects are oriented in such a way that adjacent elements in a pile fit one in the other.
