Abstract
The invention relates to an accumulating conveyor for use in body manufacturing of the motor vehicle industry, for example for conveying body parts on pallets. The movement of the pallets is restricted in the region of the relevant reversing station and said pallets are conveyed from the top strand to the bottom strand and from the bottom strand to the top strand in a form-fitting manner by means of driver wheels via driver pins, wherein the driver pins are automatically coupled and decoupled again to the driver wheels.
Claims20
Accumulating conveyor for conveying parts on pallets, comprising a motor driven, flexible tension element, which is guided in the region of reversing stations via first and second gearwheels, the first gearwheel being arranged on a first shaft and the second gearwheel being arranged on a second shaft, wherein the first gearwheel is connected in terms of drive to the first shaft for conjoint rotation, and said first shaft is driven, by an electric motor which is controllable or regulatable in the rotational speed thereof, and the second gearwheel is mounted on the second shaft via a freewheel on said second shaft, and said second shaft in the freewheel can be switched on as required by a controllable or regulatable electric motor for activating at least one predetermined angle of rotation for the purpose of driving the second shaft and can be stopped at least one angle of rotation position, with driver wheels arranged on at least the second shaft for conveying pallets.
Accumulating conveyor for conveying parts on pallets, comprising a flexible tension element which is motor-driven and which is guided in the region of reversing stations via gearwheels respectively arranged on shafts, wherein the end regions of each shaft are each assigned a driver wheel which is drivable in a slip free manner by the relevant shaft, wherein the driver wheels have radially running openings which are arranged at an angular distance from one another over the circumference of said driver wheels and in each of which a driver pin which is spring loaded towards the periphery is arranged, said driver pins automatically engaging in a form fitting manner in the relevant reversing station in driver openings arranged on opposite sides on the pallets and also being automatically released again on the opposite strand, wherein, on the loading or unloading side, the one gearwheel is arranged in a freely rotatable manner on the associated shaft via a freewheel, and said shaft is driven by an electric motor which can be switched on and off and is controllable or regulatable in the rotational speed thereof, in such a manner that, on entry into the associated reversing station, the relevant pallet passes a sensor which detects the position of the pallet and transmits a switching pulse, whereupon the electric motor sets the shaft into rotation and, on further rotation, passes a further sensor which then decelerates the rotation speed of the electric motor and, on a further rotational movement which corresponds to the loading or removal station of the pallet, switches off the energy supply to the electric motor and brings the electric motor into a stopping position, whereupon the relevant angular position of the driver wheels of the shaft is mechanically locked and, after the loading or unloading of the relevant pallet and after the mechanical unlocking, the energy supply to the electric motor is switched on again and the shaft is set into rotation and, after reaching the starting position, by the energy supply to the electric motor being switched off, the driver wheels are rotated again into the starting position thereof by stopping of the shaft.
