ABSTRACT:
FIELD OF THE INVENTION
This invention is concerned with means for inserting objects being carried on a conveyor into cartons which move along with the conveyor. A standard mechanism for this purpose has a series of pushers which are moved across the conveyor to move objects into the respective cartons, the pushers then being carried around to the start end of the conveyor to locate on to further objects to be inserted. This mechanism has a large number of moving parts in view of the fact that several independent moving pushers are employed and occupies a substantial width to one side of the conveyor, for location of the pushers in their extended state.
SUMMARY OF THE INVENTION
According to the present invention there is provided a carton filling device comprising a conveyor for moving cartons and objects to be located in the cartons simultaneously down a track with the objects respectively facing opposite to open ends of the cartons located at one side of the conveyor, and a control arm situated in a start position at the other side of the conveyor and carrying pushers for engaging the objects and pushing them towards and into the open ends of the cartons under control of a control mechanism adapted to move the control arm not only across the conveyor, but also down the conveyor at the same speed of movement as the conveyor and to return the control arm back to the start position once the objects have been inserted into the cartons.
With such an arrangement the pushers are moved by means of the control arm essentially diagonally across the track followed by the conveyor and are then brought back, along the same diagonal line, to the start position. Pushers are not carried around with the conveyor as in the previous mechanism.
In the preferred arrangement the pusher arm will carry two to four pushers for engaging respective objects. These pushers are carried by a single control arm of the control mechanism so that the number of relatively moveable parts is kept to a minimum. Preferably the control mechanism is designed to cause the pusher arm to be raised for the return journey back to the start position. This ensures that there is no fouling with parts of the conveyor or further objects to be moved. A support body can be situated beside the conveyor to support the control mechanism which controls the movement of the control arm.
