Abstract

Abstract There is disclosed a method and an apparatus for loading containers with single pieces by which a plurality of single pieces are stacked on top of each other and subsequently several stacks are assembled into a block having a size substantially corresponding to the dimensions of the freight space of the container. In one embodiment, the pieces are enveloped in plastic sheet prior to stacking. Two containers may be loaded alternately. The apparatus comprises one or several stacking devices for stacking the single pieces, a packing device if desired and various conveyors and transfer devices for feeding the stacks to a tilting frame on which the container may be mounted. Loading of the assembled blocks of single pieces into the container is effected by tilting the tilting frame. The drive means of the various devices may be coupled through control means to a common program controller.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 229 words
An apparatus for stacking and subsequently loading pieces into a container, comprising, in combination, a first conveyor operable for feeding successive pieces in one direction, a stacking device disposed near the first conveyor and being operable for lifting a piece from the feeding conveyor and stacking it on another piece; control means operative for controlling the operation of the stacking device in response to the position on the conveyor in its movement in said one direction of a succeeding piece prior to its reaching the stacking device, a second conveyor cooperating with a discharging part of the first conveyor to receive therefrom succeeding stacks and to move the stacks in a direction at an angle to said one direction, at least one support movable between a transfer poSition in which it is operable to receive at one portion stacks from the second conveyor and, respectively, a loading position at an angle to said transfer position, and transfer means operable for transferring the stacks from the second conveyor onto said one portion of the support when the support is in the transfer position, said support being adapted to support at another portion a container, whereby during movement of said support from said transfer position to said loading position, the stacks will be shifted from said one portion of the support towards said other portion and be loaded into the container.
Claim 2
Independent Claim 229 words
An apparatus for stacking and subsequently loading pieces into a container, comprising, in combination, a first conveyor operable for feeding successive pieces in one direction, a stacking device disposed near the first conveyor and being operable for lifting a piece from the feeding conveyor and stacking it on another piece; control means operative for controlling the operation of the stacking device in response to the position on the conveyor in its movement in said one direction of a succeeding piece prior to its reaching the stacking device, a second conveyor cooperating with a discharging part of the first conveyor to receive therefrom succeeding stacks and to move the stacks in a direction at an angle to said one direction, at least one support movable between a transfer poSition in which it is operable to receive at one portion stacks from the second conveyor and, respectively, a loading position at an angle to said transfer position, and transfer means operable for transferring the stacks from the second conveyor onto said one portion of the support when the support is in the transfer position, said support being adapted to support at another portion a container, whereby during movement of said support from said transfer position to said loading position, the stacks will be shifted from said one portion of the support towards said other portion and be loaded into the container.
Claim 3
Dependent Claim 330 words
An apparatus according to claim 1, wherein said first conveyor is a roller conveyor, said stacking device being arranged adjacent the roller conveyor and comprising a frame, a lifting platform vertically movable in said frame, lifting forks on said lifting platform at the end of the platform facing the roller conveyor and adapted to be lowered between the rollers of the roller conveyor when the lifting platform is in its lowered position, said control means including control devices arranged adjacent the stacking device in the path of movement of the single pieces on the roller conveyor and adapted to be actuated by the single pieces, the control devices coupled to drive means for lifting and lowering the lifting platform; said second conveyor being a transfer and storage conveyor arranged transversely of the roller conveyor at the discharge side of the roller conveyor, and including a pair of roller tracks arranged one behind the other with an intermediate spacing corresponding substantially to the width of said first roller conveyor adjacent the stacking device, and transfer devices for the stacks formed of two single pieces one on top of the other whereby said roller tracks are mounted in carriage type frames movable by means of drive means transversely of said first roller conveyor; said support including a pair of tilting frames tiltable about their mid portions and arranged such that each tilting frame is opposite to an outer end portion of one roller track of said pair of roller tracks of said transfer and storage conveyor and extends transversely thereof, each tilting frame including a first frame section facing the transfer and storage conveyor and connected at its lower side to a lifting device, a roller track in said first section having rollers extending parallel to the rollers of said pair of roller tracks and a second frame section in the extension of the tilting frame roller track and which is arranged in the form of a support plate for a container.
Claim 4
Dependent Claim 16 words
An apparatus as in claim 1 wherein several stacking devices are arranged adjacent the first conveyor.
Claim 5
Dependent Claim 65 words
An apparatus as in claim 2 wherein the rollers of the pair of roller tracks of the transfer and storage conveyor are mounted in the movable carriage type frames such that when moving said pair of roller tracks these rollers may pass between the rollers of the first-mentioned roller conveyor which extends intermediate of said pair of roller tracks of said transfer and storage conveyor.
Claim 6
Dependent Claim 43 words
An apparatus as in claim 1 further including a device for packing the single pieces in synthetic sheet or heat shrinkable thermoplastic sheet, said device being mounted upstream of the first conveyor and operable for supplying a succession of packed single pieces thereon.
Claim 7
Dependent Claim 88 words
An apparatus as in claim 2 wherein the drive means of the stacking device, of the pair of movable roller tracks of the transfer and storage conveyor, of the tilting frames with the containers, of the transfer devices for transferring the stacks from the movable roller tracks of the transfer and storage conveyor onto the roller tracks of the tilting frames, and of the first-mentioned roller conveyor are coupled to additional control means for controlling the various movements, and the control means are combined in a program controller.
Claim 8
Dependent Claim 18 words
An apparatus as in claim 2 wherein the rollers in said pair of rolLer tracks are individually power-driven.
