Abstract
Abstract A packing machine for transferring articles such as milk cartons and similar objects from a conveyor via a conveyor plate laterally into a crate container or the like such that the cartons will be packed in the container in a uniform pattern, one layer of cartons on top of the other, without any gap forming between the adjacent cartons. The packages are fed onto the conveyor plate between a movable guide edge extending along the conveyor plate discharge edge and a guide edge mounted rigidly on the conveyor plate, and they are thereby prevented from spreading on the conveyor plate but will be positioned thereon closely adjacent each other.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
198 words
An improved packing machine for packing articles, such as milk cartons or similar packages in a container, the machine comprising a conveyor which is arranged at one side of the machine and adapted to forward the milk cartons or other similar packages or articles to be packed, a pusher means, a conveyor plate onto which the pusher means feeds a row of packages laterally from the conveyor, a follower means provided on said conveyor plate, the said conveyor plate being adapted to be moved substantially horizontally into the container, the conveyor plate and the container being arranged to assume different vertical positions relatively each other, and a means for stripping the packages off the conveyor plate when the latter returns to its original position, the improvement comprising a guide edge extending along the edge of the conveyor plate facing the container and being perpendicularly to the conveyor, the said guide edge being arranged to be moved out of the path of movement of the conveyor plate, when the latter is being displaced in over the container, and to be returned to its original position, in which the plate is again ready to receive the articles to be packed.
Claim 2
Dependent Claim
198 words
An improved packing machine for packing articles, such as milk cartons or similar packages in a container, the machine comprising a conveyor which is arranged at one side of the machine and adapted to forward the milk cartons or other similar packages or articles to be packed, a pusher means, a conveyor plate onto which the pusher means feeds a row of packages laterally from the conveyor, a follower means provided on said conveyor plate, the said conveyor plate being adapted to be moved substantially horizontally into the container, the conveyor plate and the container being arranged to assume different vertical positions relatively each other, and a means for stripping the packages off the conveyor plate when the latter returns to its original position, the improvement comprising a guide edge extending along the edge of the conveyor plate facing the container and being perpendicularly to the conveyor, the said guide edge being arranged to be moved out of the path of movement of the conveyor plate, when the latter is being displaced in over the container, and to be returned to its original position, in which the plate is again ready to receive the articles to be packed.
Claim 3
Dependent Claim
79 words
A machine as claimed in claim 1, including a preferably pneumatically operated driving means to control the conveyor plate, wherein the guide edge being pivotable about a transverse shaft and adapted, while the conveyor plate assumes its original position, to be swung up against the discharge edge of the plate so as to extend above the plane of said conveyor plate, control means operable by said driving means and being arranged to control the movement of said guide edge.
Claim 4
Dependent Claim
89 words
A machine as claimed in claim 1, wherein vertically positioned side pieces extend in a horizontal direction forwards, into the container on either side of the conveyor plate above the conveyor plate plane, and inside the short sides of the container, and wherein the pusher means is adapted, when the conveyor plate is completely filled with packages, to be retained in its inner end position at the siDe edge of the conveyor plate, until the said conveyor plate with the packages thereon, has reached its position inside the container.
Claim 5
Dependent Claim
43 words
A machine as claimed in claim 3, wherein the side pieces consist of side plates which are fixedly attached in the machine frame, the side piece remote from the conveyor merging into a stop plate for the packages discharged onto the conveyor plate.
