Definitions

• the present invention is concerned with a collecting carriage for picking up a certain number of boxes from a sta k consisting of boxes placed one above the other, Jhe said stacks being placed one after the other on storage tracks placed one alongside the other.
• Collecting carriages of the type concerned are used, e.g., in forwarding departments, such as wholesale companies and equivalent, from which several different types of merchandise are delivered to retail stores as packed into boxes. Each type of merchandise has been packed into boxes so that each box contains the same quantity of the merchandise concerned.
• the boxes are stacked to stacks of several boxes placed one above the other, and the said stacks are placed one after the other on a warehouse conveyor, such as gently forwards slanting roller track, on which they travel towards the collecting device.
• Each type of merchandise is placed on a track of its own, and the said tracks are placed side by side as parallel to each other.
• the collecting carriage has been arranged so that it runs bacTc and forth along a track placed transversely in front of the storage tracks.
• the col ⁇ lecting carriage is run either as manually controlled or as programmed, in accordance with the orders to be delivered, to positions facing the different lines of box stacks, from which lines the collecting carriage picks up the desired number of boxes from each selected stack.
• the collecting carriage is provided with appro ⁇ priate grasping members, such as a pair of grasping arms, whose arms can be pushed to the sides of a stack of boxes and pulled towards each other so as to grasp a box.
• the pair of grasping arms is supported by an appropriate lifting device, by means of which the pair of grasping
• This lifting- device usually also includes a conveyor device, which receives the boxes lifted and pulled out of the stack from the pair of grasping arms as well as delivers the boxes further to an exit conveyor for carriage forwards. It is drawback of the prior-art collecting carriages that the conveyor receiving the stack of boxes from the grasping members must be lowered to the level of the receiving conveyor and that the stack of boxes must be run from it onto the receiving conveyor before the grasping members can be run to a new grasping posi ⁇ tion. This of course imposes its limitations on the speed of operation of the apparatus.
• the receiving conveyor must be parallel to the storage conveyor, whereat the collecting carriage must always be driven to the posi ⁇ tion facing this conveyor for the delivery of the stack of boxes picked up.
• the drawing shows a construction of a collecting carriage, of a basic construction in itself known, which consists of a carriage 6 moving back and forth along rails or a corresponding guiding base as controlled in respect of its location.
• the carriage includes a sledge controllably movable in the vertical direction, and on that sledge are supported a pair of grasping arms 3 forming the grasping member as well as a conveyor 4, so-called delivery conveyor. receiving the stack of boxes from the pair of grasping — arms.
• a receiving member 5 receiving the stack of boxes from the conveyor 4 is installed on the carriage, which said receiving member can be raised and ⁇ ,lowered as controlled in support on its own support device 7.
• the receiving member 5 can be turned around its vertical axis at least over about 90 degrees.
• exit conveyor 2 may be placed as parallel to the track of running of the carriage, whereat the quantities of boxes collected from the storage stacks can be placed onto the conveyor concerned as stacks placed one after the other.
• the receiving member 5 preferably comprises two fork-shaped support arms, onto which the stack of boxes can be run off the delivery conveyor.
• the top face of " the forks is preferably outwardly slanting, whereat, when the receiving member has been lowered onto the exit conveyor and turned so as to be parallel to the said conveyor, the stack of boxes remains on the exit conveyor when the carriage continues its movement or when the exit conveyor is started.
