DESCRIPTION:
BRIEF SUMMARY
The invention relates to a device for placing objects, in particular filled bags, in a row comprising: a substantially horizontal transport plane; substantially horizontal transport plane, angularly distanced from each other and cam means between said pockets to provide the space for a subsequent object on the discharge means, direction of the discharge means, as disclosed in GB-A-343,586.
Mechanisms for forming a row from objects such as filled bags in such a way that said objects overlap are known. In general, these mechanisms work in such a way that the objects overlap slanting forward, viewed in the direction of feed, on a conveyor belt: each object is placed or pushed on another object. It has been found that a row of overlapping objects slanting forward formed in this way will often have irregularities when they are moved to an upright position, due to the fact that the top edges of the objects are not lying at the same height. In the case of smooth filled bags this disadvantage is aggravated by one or more bags sliding up when the row is being placed in the upright position.
The device described in GB-A-343,586 does not give a solution for this problem since the packet shaped objects are deposited in a vertical direction on the discharge means and do not overlap each other.
The object of the invention is to avoid the abovementioned disadvantage and to provide a device with which objects can be placed coordinated in such a way in a row that they overlap slanting backwards, viewed in their feed direction, and if a row of bags is swept together to an upright position, the top edges of the objects lie essentially in one plane.
According to the invention, the device mentioned in the preamble to this end is characterized in that the discharge end of the infeed means and the infeed end of the discharge means extend within the active rotational path of the rotational transfer mechanism, and to provide said space for a subsequent object on the discharge means, the diameter of the cam means--as viewed in the rotation direction decreases gradually from one pocket to the next pocket where there is a diameter jump such that the objects are deposited in a slanting backwards overlapping position.
The infeed and discharge means can be driven conveyor belts.
In order to prevent the objects placed in a row from slipping, the conveyor belts for discharge of objects placed in a row can be provided with a profile.
The device can have two rotors placed on one shaft, in which case the infeed means extend with its discharge end and the discharge means extend with its feed end between the two rotors.
There is a possibility of the device having two adjacent feed belts and two adjacent discharge belts extending with their discharge ends and feed ends respectively on either side of the rotor or rotors.
The device can also be provided with means for pushing a number of backward slanting bags on the discharge conveyor belt(s) in the upright position against a stop.
Said means can comprise a partition and a mechanism for successively moving the partition upwards near the rotor, in a direction away from the rotor, downwards, and in a direction towards the rotor.
The invention will now be explained in greater detail with reference to the figures.
FIG. 1 shows a perspective schematic view of a part of a first embodiment of the device according to the invention.
FIG. 2 shows a perspective schematic view of a part of a second embodiment.
FIG. 3 shows a side view of the device according to FIG. 2, also provided with means for pushing objects collected in a row into an upright position against a stop.
FIG. 4 shows a side view corresponding to that of FIG. 3, in which a row of objects is pushed into the upright position against a stop.
The device according to FIG. 1 has two conveyor belts 1 placed next to each other some distance apart for the infeed of objects to be placed in a row, two conveyor belts 2 placed next to each other some distance apart for the discharge of overlapping objects arranged in a row slanting backwards, and a roto
