Definitions
- the machine-readable postcodes to be specified on postal items such as letters, postcards, small parcels and the like, as an identification number for a location, a delivery area, a mailbox or a bulk recipient, enable a quick mechanical distribution of the post.
- the incoming mail items are sorted, for example, with the aid of controllable general cargo carriers, each of which is loaded with a mail item in special loading places, and then deliver this mail item to a sorting container assigned to the respective zip code or a corresponding sorting compartment. Since the sorting containers or sorting compartments can be arranged on different levels, the piece goods carriers rotating on conveying devices may also have to be able to bridge different altitudes.
- the empty general cargo carriers can be loaded again with a mail item when passing through a loading place.
- the general cargo carriers are loaded, for example, with the aid of a rotating impeller, the blades of which form cells which receive the individual cargo that has already been separated and arrives on a conveyor device and deliver it to the rotating general cargo carriers.
- the separation and transfer of the piece goods to the conveying device leading to the impeller must be carried out with a relatively high degree of accuracy adapted to the processing speed of the entire sorting device.
- Comparable sorting tasks also result from the so-called remission of magazines or newspapers.
- the publications that are not sold by retailers are returned to the wholesaler here, where they are recorded and used for sale. not sorted out or re-sorted for return to the respective publishers.
- the invention specified in claim 1 is based on the problem of creating, with little effort, a rapidly and reliably working device for separating and transferring flat piece goods, in particular the safe handling of magazines, newspapers, catalogs and the like guarantee.
- a device according to the invention can be used in the remission of magazines or newspapers, in public post offices or in the company mail centers of large companies.
- a device according to the invention can also be used, for example, in storage systems or automatic picking devices for comparable tasks, in which flat, stackable piece goods are to be separated and transferred to a conveyor.
- the invention is based on the finding that the rotation movement of a drum provided with a feeding opening or several suction openings is very well suited for the separation and transfer of magazines or newspapers. If the spine or fold of the printed matter is at the rear as viewed in the direction of rotation of the drum, non-stitched printed matter is held together and any loose inserts which may be present cannot fall out. Through the the upright position of the piece goods is favored because the piece goods provided in the pick-up position are pulled upwards, while the next piece goods counteracts the pulling force by its own weight. Since the piece goods do not have to be pulled off against an edge, a separation of piece goods with different thicknesses is also made possible.
- the embodiment according to claim 2 enables a particularly simple stacking of the piece goods to be separated.
- the provision of the piece goods on a belt conveyor can be realized with a significantly lower construction expenditure than the provision in magazines.
- the refinement according to claim 4 enables, by means of the deflectors which can be switched on and off, a targeted take-away of the piece goods provided in the pick-up position at the respectively desired time.
- the development according to claim 5 ensures absolutely secure guidance of the piece goods between the pick-up position and the drop-off point, this guidance according to claim 6 being able to be implemented in a particularly simple manner by means of an endless belt.
- the development according to claim 7 enables a coordination of the entire device for the separation and for the transfer of piece goods to a division of the conveyor device receiving the piece goods.
- two or three devices is then occupied by one device only every second or third division of the conveyor.
- the device can also be matched to an uneven division of a conveyor.
- two or more separations and transfers can be made per revolution of the drum.
- the embodiment according to claim 9 enables complete compensation of any slip that may occur when the piece goods are gripped by simple means.
- Figure 1 is a side view of a device for separating and transferring magazines and newspapers and
- FIG. 2 shows a top view of the device according to FIG. 1.
- FIGS. 1 and 2 show a highly simplified schematic illustration of a device for separating and transferring piece goods S to a conveyor device designated F in a side view and in a top view.
- a device designated E is provided to accommodate the piece goods S present here in the form of magazines and newspapers, in different formats and different weights, and to provide this piece goods S in a front collection position A.
- This device E not shown in FIG. 2, is a horizontally oriented belt conveyor that can be driven step by step in the direction of the pick-up position A, on which the piece goods S are stacked by hand in an upright, slightly inclined forward direction Position is applied.
- a drum T is provided above the conveyor device F so as to be rotatable about its longitudinal axis LA, in the jacket of which a total of three suction openings SO lying side by side are introduced.
- the pocket-shaped suction openings SO can be connected via suction channels SK to the interior of a hollow shaft HW on which the drum T rotates.
- the interior of the hollow shaft HW is in turn connected to a vacuum source, not shown in the drawing.
- the segment-shaped opening of the hollow shaft HW in the area of the suction channels SK which can be seen in FIG. 1, creates a type of rotary slide valve, via which the suction openings SO are connected to the vacuum source when the pick-up position A is reached.
- the piece goods S provided in the pick-up position A are thus gripped by the drum T by the suction effect of the suction openings SO and are pulled slightly obliquely upward in the tangential direction of the drum T.
- the aforementioned rotary slide formed by the hollow shaft HW interrupts the connection of the suction openings SO to the vacuum source and the individual piece S is transferred to the Conveyor F dropped.
- the magazines or newspapers set up as piece goods S on the conveyor belt of the device E with the back or fold downward and slightly inclined towards the drum T can be prevented from touching the drum T by two deflectors AW arranged at a distance from one another be held. If the piece goods S provided in the pick-up position A are then to be gripped via the intake openings AO, the two deflectors AW are withdrawn into the associated groove-shaped depressions V of the drum T. The deflectors AW attached to the shaft WE are engaged and disengaged by corresponding rotations of the shaft WE.
- a guide device FE for the piece goods S is assigned to the drum T.
- This guide device FE is formed by an endlessly revolving belt B, which is guided over three guide rollers UR in such a way that it wraps around the drum T in the desired guide area.
- the direction of rotation of the belt B is shown in FIG. 1 by an arrow PF.
- the belt B can be driven or can also be frictionally entrained by the drum T rotating at the speed n.
- Band B which is only shown in FIG. 1, is divided into a plurality of belts running in parallel.
- an optical sensor SS can be arranged in the area between the three deflecting rollers UR, which detects the beginning and / or end of the piece goods S carried along by the drum T at this point between two belts.
- the signal SI from the sensor SS is fed to a control device SE.
- This control device SE in turn influences via an output signal AS a drive motor AM which drives the drum T via a belt drive RT and the drum shaft labeled TW.
- the bearing of the drum shaft TW is indicated in FIG. 2 by ball bearings KL.
- the sensor SS thus detects the position of the piece goods S detected by the suction openings SSO on the drum T. Any slippage determined by the sensor SS when gripping and carrying the piece goods S can thus be made via the control device SE by a corresponding change the speed n of the drum T can be compensated.
- the conveyor device F receiving the individual piece goods S is a belt conveyor, the conveyor belt (not shown) of which moves at the speed u in the direction of transport.
- transverse ribs QR create a division t for the reception and further transport of the piece goods S.
- the speed u of the conveyor device F and the The rotational speed n of the drum T are coordinated with one another in such a way that the piece goods S are transferred to the conveyor F at each division t or an integral multiple of the division t of the conveyor F.
- the above-described device for separating and transferring piece goods S leads to a rotating vane wheel, the cells formed by the individual wings of which receive the piece goods S arriving on the conveying device F and, after a corresponding rotation, to one of the rotating piece goods carriers Submit sorting device.
