Definitions
- the invention relates to a device for supplying flat Objects such as Letters, large letters, cards, to one Suction singler according to the preamble of the claim 1.
- the levers 3 act statically as a brake between the trigger system and the item to be deducted and reduce the frictional force during the withdrawal process. Furthermore, the lever 3 "measures" at the moment in which the object is sucked against the friction elements, not the stack 4, but only the adjacent object. Only when the object is pulled out of the lever mechanism, the lever 3 can detect the stack 4. In terms of a high take-off performance, the tracking system must be very fast and / or integrate over several cycles.
- the invention is therefore based on the object, a device for feeding flat objects to a friction-suction singulator to be created by the the objects at the take-off point detecting measuring means for controlling the objects transporting to the withdrawal point Promoter no negative effects on the Deduction process done.
- the negative pressure in the Suction trough measures, depending on the measured negative pressure and thus the distance and / or the inclination of the front object, the greater the negative pressure, i. ever lower the absolute pressure, the smaller the distance and / or the inclined position, the funding is controllable, that the foremost object on / at the friction extractor the lowest possible inclination with the lowest possible stacking pressure has, are negative on the removal process impact of measurement, such as the use of feeler levers, avoided.
- the structure of the measuring device simplified.
- the distance of the objects from the friction extraction means, from which they are pulled by the negative pressure to the friction extraction means strongly depends on the mass of the objects, it is advantageous to integrate the measured values of the sensor in the drive control and the conveyor accordingly the current integrated values. In this context, it is particularly advantageous to form average values from the measured values of the sensor, according to which the conveying means is moved.
- the height of the respective object to measure and execute the drive control so that in shipments that are not all due to their height Suction troughs cover, the negative pressure of the not or only partially covered suction cups can not be evaluated.
- a friction-release means a circumferential To provide discharge belt with suction openings, wherein the Negative pressure of the suction trough behind it over the suction openings acting on the respective foremost object.
- a friction-suction-singling device which has a peripheral discharge belt 1 with suction openings as a friction-withdrawal means.
- a suction trough 2 which is connected to a vacuum source 8, directly behind the area of the draw-off strip 1 with a high coefficient of friction.
- the stack 4 flat objects is on a conveyor belt 5 as a conveyor and is supported on the back of a non-illustrated contact surface, which can be moved with the conveyor belt 5 in the direction of separating device.
- the stack 4 is aligned with a stop surface 6 standing laterally on the conveyor belt 5.
- the sensor 7 on the suction trough 2 constantly measures the negative pressure prevailing in the suction trough 2.
- the negative pressure is realized by an externally arranged vacuum source 8 (suction pump).
- suction pump suction pump
- the withdrawal operation is started, and the negative pressure source 8 generates a negative pressure. If an object rests flat against the extraction unit, a specific negative for the Gutspektrum will adjust. If the shipment is not flat, but is in one of the two types mentioned above for the withdrawal unit, a slight negative pressure will form, ie the absolute pressure increases, as a function of the gap size secondary air is drawn.
- the prevailing negative pressure is thus directly an expression of the position of the objects to the deduction unit.
- the sensor 7 registers the negative pressure conditions and signals the controller when the negative pressure in the suction trough 2 becomes too low, ie when the measured absolute pressure exceeds the nominal value.
- the drive control then starts the conveyor belt 5.
- the conveyor belt 5 moves the stack 4 in the direction of the take-off belt 1.
- the next object is transported into the intake area and there grabbed by the suction air and sucked to the discharge belt 1. Because now the object is parallel to the Saugwannenö réelle, the negative pressure increases, ie the absolute measured pressure decreases, the measured value of the sensor 7 reaches an adjustable target value and thus the conveyor belt 5 is switched off by the drive control and the object is subtracted.
- the device described has the advantage over known solutions that the function of the stack tracking has no mechanical elements, levers / springs more. The size required for measurement no longer counteracts the process to be controlled. Instead of the two way / force sensors described in the prior art, only one sensor is now required. The solution is thus compared to the prior art cheaper, easier and easier to maintain.
