Definitions
- the invention relates to a method and a device for unloading an open-top mail container according to the preambles of the independent claims.
- the object of the invention is therefore to enable a method for semi-automatic or fully automatic emptying of open-top mail containers with obliquely outwardly extending side walls so that the mail items are unloaded gently while maintaining the orientation and orientation.
- a device in this regard is to be created.
- the corresponding device is shown in independent claim 4.
- the mailings are removed with the steps and means specified in such a way that the aligned position of the mailpieces in the stack is maintained and no mailing and wrinkling forces occur.
- the stack is compressed and clamped between the support brackets with circulating conveyor belts during unloading.
- the conveyor belts are moved in such a way that no other forces are exerted on the mail items touched in addition to the normal force.
- the swiveling and traversing movements are carried out by means of conventional and known handling systems with NC-controlled axes, which are therefore not shown here.
- FIG. 1 a shows a schematic side view of a mailing container loaded with standing mail items
- FIG. 1b shows a schematic side view of the mailing container with compressed mail stack
- FIG. 1c shows a schematic side view of the mailing box with compressed mail stack held between holding supports with conveyor belts
- FIG. 2a-e shows schematic representations according to section BB of FIG of consecutive
- the mail container 1 is shown transparently with side walls that extend obliquely outwards. He is loaded with a loose stack of 2 standing items.
- the stack of mail items is compressed by moving the handle recesses on the side. tels stamps, which are not shown, is pressed against the mail items (indicated by the arrows 3). If necessary, the pressures can also be measured in order to maintain a specified compression pressure.
- the mail container is fixed in a holding and positioning device, not shown.
- support brackets 4 are moved from above to the stack of mail items 2 and into the free space between the stack and the container side wall. During this downward movement of the support brackets 4, the revolving conveyor belts are driven in such a way that the contacting belt sections to the shipments are always motionless. As a result, the shipments are prevented from damaging stresses caused by the holding supports 4. Retaining supports 4 and stamp are coordinated so that they do not interfere with each other when holding the stack of mail 1.
- FIG 2a shows again the state according to FIG lc.
- the mail item container 1 was transported on a transport path 5 designed as a roller conveyor.
- the holding supports 4 each have three conveyor belts.
- the holding and positioning device for the mail container 1 is not shown for the sake of clarity. However, there is a pivot point 7 in a longitudinal axis about which the holding and positioning device with the mail container 1 and the mail items can be pivoted. Furthermore, a movable stop wall 6 can be seen, the function of which will be explained.
- the shipment container 1 with the shipment stack 2 and the support brackets 4 has been pivoted by approximately 95 °. Thereby is secured that in a 'eventual breaking of broadcasts of the stack these STO against the underlying container wall eat.
- stop wall 6 is moved to the other long side of the stack of mail 2 for safety in order to prevent a particularly unstable stack of mail 2, e.g. to be avoided with particularly large differences in the size and thickness of the mailings towards this side (FIG. 2c).
- the stack of mail items 2, base plate 8, support brackets 4 and mail container 1 with holding and positioning device are pivoted back to one another while maintaining the spatial position such that the stack of mail items 2 with the base plate 8 underneath is aligned horizontally.
- the mail item container 1 is released from the holding and positioning device and falls down onto the transport path 5, which transports it to the right (FIG. 2e).
- the base plate 8 with the stack of mail items 2 clamped thereon is at such a distance from the transport path 5 that the mail item containers 1 are not obstructed by the base plate 8 and the stack of items 2 during transport.
- the batch of mail items 2 can now be fed to further processing. This can be sorting in a sorting system.
- the stack of mail items 2 is transported with the base plate 8 onto the material input.
- the holding supports 4 can be moved upwards so that the stack of mail 2 Cutting knife is taken over and can be transported to the separation point.
- a consignment container 1 If a consignment container 1 is not completely filled, the consignments are prevented from tipping over by a holding clamp which is attached to the consignment container.
- the holding clamp is shaped so that the stamp can compress the stack of mail through it.
