Abstract: 1475473 Apparatus for the deposition of stacked goods on to pallets KOMBINAT UNFORMTECHNIK VEB 1 Sept 1975 [6 Sept 1974] 35889/75 Heading B8C An apparatus for the correctly positioned deposition of goods layered in stacks on to pallets during loading and transloading comprises a support 2 upon which a pallet 3 can be lowered, bracing elements 4 arranged at right angles to the support 2 and adapted to protrude through perforations in the pallet, the upper ends of the bracing elements constituting a common bracing plane 5 for the stack, and guide elements 8, for the pallet, on the support 2, at least two of the guide elements 8 being provided which are arranged on mutually adjacent sides of the support and with which adjustable stack stops 10, mounted horizontally above the bracing plane, co-operate. A substantially rectangular frame of profile iron sections provides a base frame which forms the support 2 to which the bracing elements are adjustably secured in several spaced-apart rows. The guide elements 8 in the form of vertical bars and with outwardlyinclined upper ends 8À1, are connected to three sides of a substantially rectangular frame 7 which surrounds the support 2, a horizontally adjustable stack stop 10 being arranged between each pair of guide elements 8. Each stop comprises a stop plate 12 fixed to rods 13 which are slidably guided in a basic element 11 the plate 12 being movable towards, and away from, the element 11 by a spindle 14, Fig. 2, and secured in its selected position by clamping screws 15. The basic element 11 is fixed to a rocking shaft 16 mounted upon the frame 7, two rocking arms 17 being fixed to the shaft 16 so that, in the inoperative position of the stack stop, wherein a support surface 11À2 of the element is in abutment with the frame 7, they project into the pallet capacity space 9, as shown by chain dotted lines, Fig. 3. In the operative position, a support surface 11À1 of the element 11  rests upon the frame 7 and the stop plate 12 extends vertically within the space 9. The rocking arms 17 are associated with spring units 18- 21 which urge the element 11 into one of its two limit positions. In operation, with the stack stops 10 rocked out to their inoperative positions so that the rocking arms 17 protrude into the space 9, an empty pallet 3, centred by the inclined guide ends 8À1, is lowered, by means of a crane or fork lift truck, on to the support 2, the pallet striking the rocking arms 17, during lowering, to rotate the stack steps 10 into their operative positions. A stack of metal sheets 6, guided by the stop plates 12, is then lowered, by crane or fork lift, on to the tops 5 of the bracing elements 4 so that support timbers 24 for the stack 6 and support ropes, or forklift fork can be removed without obstruction. The pallet 3 is then raised during which it first strikes counter surfaces 11.3 on the basic elements 11 and rocks out the stack steps 10 and then lifts the stack of sheets 6 from the bracing plane 5, the rocking arms 17 again projecting into the space 9 for the reception a fresh pallet 3. A scale 22 is provided on one of the guide rods 13.
