Definitions
- the invention relates to a device for transporting flat mail items in an upright position according to the preamble of claim 1.
- Such systems can only be used for larger and thicker formats and mailpieces that have a very low bendability if very large gaps and lower speeds are used.
- U-channel systems EP 0 444 177 B1
- U-channel systems EP 0 444 177 B1
- U-channel system with moving base and side belts consists of transport channels the width of the thickest consignment.
- the program 'without any relative movement to each other are transported safely.
- extremely thin, flaccid consignments can collapse in the up to 50mm wide channels (collapse) and can no longer be erected from this state in order to be shown to a scanner over the entire surface.
- the invention has for its object to provide a reliable device for transporting flat mail items in different formats in an upright position with the least possible transport slip of the mail items to each other and to the transport device, which feed the mail items in a defined position to process devices. According to the invention the object is achieved by the features of claim 1.
- the distance between the side guide belts at the module ends is greater than the thickest consignment to be transported.
- the height of the first lateral guide band is made smaller than that of the second lateral guide band.
- an elastic, narrow, endless pressure belt Arranged below the first guide belt is an elastic, narrow, endless pressure belt, which is pressed resiliently against the lower part of the second guide belt by means of pressure deflection rollers and pressed away from the second guide belt by the mail items in accordance with their thickness.
- On the brackets of the pressure guide pulleys there are guide rails that run obliquely to the direction of transport and tangentially to the pressure guide pulleys and absorb the consignments of the consignments with a low coefficient of friction compared to the consignments. This ensures that both the thick consignments are transported gently and the thin consignments with low intrinsic stiffness are securely gripped, preventing them from collapsing.
- the pressure deflection roller which presses against the second guide belt with the pressure belt, and the rear deflection roller are rotatably mounted on lever arms which are pivotably mounted in a pivot point in which the third deflection roller, which is located furthest forward in the transport direction, is rotatably attached.
- the pressure deflection roller with the pressure belt is pressed against a force by an incoming mail item according to the mail item thickness from the second guide tape. This force is generated solely by the corresponding deflection of the pressure belt running over the rear deflection roller against a tension roller of the inlet area without an additional spring element.
- a further pressure deflection roller which is pressed with the pressure belt against the deflection roller of the second guide belt in the outlet area, and via a rear deflection roller of the outlet area.
- These two deflection rollers are each rotatably attached to a lever arm.
- the two lever arms with their other ends are fastened at a pivot point and diverging therefrom, which is located approximately centrally between them in the transport direction in front of the two deflection rollers.
- the belt tension is also used to generate the pressure force.
- a particularly gentle transport of the mail items can be achieved if a lever arm is connected to an actuator in the entry and exit area, which temporarily moves the pressure roller in question according to the measured mail item thickness, position and length away from the second conveyor belt, as long as the Shipment is located on the pressure guide roller.
- the second lateral guide belt on the pro- metering device is divided into two sub-bands by means of additional deflecting rollers and if a pressure roller is arranged in front of the process device, which presses the first lateral guide band and the pressure band against the second lateral guide band.
- FIG. 1 shows a schematic sectional illustration of the outlet area of a transport module
- FIG. 2 shows a schematic plan view and an associated sectional illustration of a transport module
- FIG. 5 shows a plan view of the adjacent parts of two transport modules with active adjustment of the pressure belt.
- the lower narrow pressure belt 4 is arranged by means of a special swing combination at the entrance and exit of a belt group in such a way that it passively evades thicker mail items 6 without any negative influence (transport slip) and in doing so orientates them towards the second guide belt 2.
- the use of the lower pressure belt 4 ensures that these mail items 6 are supported in the lower area.
- the second lateral guide belt 2 takes on the function of a guide element, which, however, does not move relative to the mail item 6. This provides optimal transport for the mail items 6 with a large thickness spectrum. In addition, this transport is particularly suitable for feeding to process devices (scanners, etc.).
- the length of the transport modules is determined exclusively by the function required in each case and not by gaps between the mail items 6. With regard to the gaps, only the arrangement of additional pressure rollers 7, which the first lateral guide belt 3 and the pressure belt 4 against the second lateral one, is determined Press guide band 2. The number and the spacing of the additional pressure rollers 7 results from the spacing at which a mail item 6 of maximum thickness can follow a mail item 6 of maximum thickness, without influencing the lower pressure tape 4 in such a way that the support function for thin, limp mail items 6 is abandoned.
- the second lateral guide belt 2 on the process device is divided into two sub-belts by means of additional deflection rollers and an additional pressure roller 7 is arranged in front of the process device. which presses the first lateral guide belt 3 and the pressure belt 4 against the second lateral guide belt 2.
- an infeed swing arm consisting of three deflection rollers 12, 13, 14 arranged in the corner points of a pivotable triangle, via which the pressure belt 4 is guided and deflected.
- the pressure deflection roller 13, which presses with the pressure belt 4 against the second guide belt 2, and the rear deflection roller 14 are rotatably mounted on a pivot point at a pivot point in which the third deflection roller 12, which is located furthest forward in the transport direction, is pivotally mounted.
- Guide rails 8 are fastened to the lever arm of the pressure deflection roller 13 by means of vibration-damping elements 11. This dampens the opening shock of the rocker, particularly for thick mail items 10 with low internal damping (high hardness).
- the pressure deflection roller 13 with the pressure belt 4 and the guide rail 8 is pressed against a force by an incoming mail 10 corresponding to the mail thickness from the second guide belt 2.
- This adjustable force is generated solely by the corresponding deflection of the elastic pressure belt 4 running over the rear deflection roller 14 against a displaceable tensioning roller 9 of the inlet area without an additional spring element.
- the infeed rocker has a low moment of inertia in the sense of a low transport slip and a possibly low pressure on the consignment 6, 10.
- the triangular shape ensures that the entry angle ( ⁇ ) and so that the difference between the speed components of the pressure belt 4 in the transport direction is kept small.
- the coefficients of friction of the pressure belt 4 running over the guide rail 8 are to be chosen to be low on both sides, because when thick mail items 6, 10 arrive, the friction between the pressure belt 4 and the guide rail 8 is briefly introduced into the pressure belt 4 as additional power. On the transport side, a slight friction with the consignment 6, 10 is required because the speed of the incoming consignment 10, depending on the angle ⁇ , is greater than that of the pressure belt 4 running at the angle. In the running-in phase, there is a relative movement between the consignment 10 and lower pressure band 4.
- the second lateral guide belt 2 on the transport side and, as far as possible, the base belt 1 is provided with a high coefficient of friction compared to the mail items 6, 10.
- the outlet rocker (FIG. 4), similar to the inlet rocker, consists of a fulcrum 15 in which two diverging lever arms are attached, a further pressure roller 16 and a rear deflection roller 17 of the outlet area, both of which are rotatably attached to the free ends of the lever arms , and a displaceable tensioning roller 18 of the outlet area.
- a guide rail is also attached to the lever arm of the pressure roller 16 by means of damping elements.
- any desired rocking force can be achieved and the vibration behavior can be adjusted by the tensioning roller 18 and a suitable band selection.
- a lever arm is connected in each case to an actuator 19 in the inlet and outlet area, which temporarily presses the relevant pressure deflection roller 13, 16 over the rocker in accordance with the measured mail item thickness, position and length second guide belt 2 moves away, as long as the consignment 6, 10 is on the pressure deflection roller 13, 16.
