Abstract:
A process for controlling a channeling of parceled goods, comprising:disposing a parcel acceptance conveyor along a first path, said parcel acceptance conveyor moving at a given speed;communicating the given speed of the acceptance conveyor to a control unit;determining the position of a free space which will receive the parcel and communicating the position to the control unit;conveying a parcel along a second path, the second path intersecting the first path at an angle, the conveying taking place by way of a delivery conveyor which moves the parcel to a first transfer point, at least one call-up conveyor which further moves the parcel to a second transfer point, and a channeling conveyor which moves the parcel to the parcel acceptance conveyor;determining the position of the parcel which has stopped on the delivery conveyor and communicating the position to a control unit;determining a speed of the at least one call-up conveyor and communicating the speed to the control unit;measuring a length of a parcel to be channeled as the parcel is moved on the at least one call-up conveyor and communicating the length to the control unit;determining a length of time t2 utilized in measuring the length of the parcel with the control unit;determining a speed of the channeling conveyor to which the parcel will be transferred and communicating the speed to the control unit;calculating the acceleration and deceleration gradient for the at least one call-up conveyor prior to a transfer of the parcel to the channeling conveyor with the control unit;synchronizing a movement of the parcel to the free space by controlling the previously calculated acceleration and deceleration gradient of the at least one call-up conveyor carrying the parcel with the control unit;transferring the parcel from the at least one call-up conveyor to the channeling conveyor which is moving at a constant speed, the transferring occurring at the speed of the channeling conveyor; andsynchronously transferring the parcel to the free space on the acceptance conveyor.
