"Device for transferring piece goods fed on roller conveyors, conveyor belts or the like"

"Device for transferring piece goods fed on roller conveyors, conveyor belts or the like "

The invention relates to a device for transferring piece goods of the type specified in the preamble of claim 1.

There are a number of applications in which piece goods, e.g. packages or similar, have to be distributed. It is necessary to separate the packages conveyed on feed conveyors and then distribute them to further conveyor systems, which is done using transfer devices. For example, so-called tilting sorters are used, in which a conveyor element either remains at rest so that the piece goods can be fed straight across the sorter, or a lateral tilting movement takes place in order to move the piece goods to the left or right onto further conveyor belts, roller conveyors or similar.

Such devices are known, for example, from the applicant's DE-U-297 00 107 or AT-E-24 461-B, DE-A-32 15 744 or FR-A-2 704 844, to name just a few such examples.

The disadvantage of the known solutions is that they

usually cannot be operated in continuous flow, i.e. the relevant sorting conveyor is briefly stopped for sideways swinging or tipping. This inevitably leads to delays in distribution.

The object of the invention is to create a solution that makes it possible, in particular, to synchronously distribute such piece goods to different, additional conveyor tracks, with a robust design and optimal control options.

With a device of the type described at the outset, this object is achieved according to the invention in that two turntables equipped with driven rollers, essentially corresponding to the width of the feed track, are provided one behind the other and can be adjusted at a lateral angle to the straight feed direction, with conveyors, such as roller conveyors, belts or the like, being arranged next to the turntables as the start of further conveying means.

With the possibility of turning two turntables sideways at an angle, it is possible to enable a passage through the device with the turntables not turned, while at the same time diverting to other conveyor systems to the right or left of the device according to the invention is possible.

·

Device possible.

With the adjustable turntables, which have driven rollers, it is possible to achieve a distribution of the transported goods in a simple but extremely cost-effective design. The intermittent distribution according to the state of the art (driving onto the distribution element, stopping, moving sideways, exiting) is made unnecessary with the present invention, which naturally leads to a very high distribution speed.

Further embodiments of the invention emerge from the subclaims, whereby it can be particularly expedient to adjust the turntables either synchronously in pairs or in quick succession, whereby the turntables themselves can also be rotated at different angles of attack, for example when a sensor detects a relatively long piece of goods which needs to be moved sideways.

Driven conveyor rollers can be provided parallel to the conveying direction in the corner areas resulting from the turntables, as the invention also provides in a further embodiment.

It is particularly useful to have in addition to the turntables in

At least one lateral, driven longitudinal roller must be provided in the longitudinal direction of the two turntables. Here, pairs of rollers or the like can also be provided.

According to the invention, the turntable adjustment is computer-controlled with underfloor servomotors, whereby a light barrier, a scanner or similar can be arranged in the short range in front of the first turntable to trigger an actuating pulse.

The invention is explained in more detail below with reference to the drawing, which shows in

Fig. 1 is a plan view of the device according to the invention in a simple representation with turntables arranged in pairs,

Fig. 2 is a front view approximately according to arrow II in Fig. 1,

Fig. 3 a top view in the representation according to Fig. with the turntables not adjusted for straight running and in

Fig. 4 is a top view of the system with additional lateral conveyors arranged on the left and right.

The device, generally designated 1 in the figures, consists of a pair of turntables 3 equipped with driven rollers 2, designated 3a and 3b, which are rotatably arranged in a common frame 4.

Fig. 1 shows that the two turntables 3a and 3b are pivoted laterally to the right, relative to the feed direction indicated by arrow 5. This adjustment position is also shown in Fig. 4, while Fig. 3 shows the unadjusted position of the turntables relative to the feed direction 5.

In the dead spaces or corner areas formed by the turntables 3a and 3b, rollers 6 are arranged, positioned transversely to the conveying direction 5, and are also driven, whereby the respective drives are only indicated in Fig. 2 via belts 7. The rollers on the turntables are driven by a central drive belt 7a, which is only partially indicated in Fig. 1 at the turntable 3b.

As can also be seen from Fig. 1 to 3, in the longitudinal direction of the frame 4 carrying the two turntables, there is a longitudinal conveyor roller or roller 8 on the outer edge.

arranged. Pairs of rollers can also be provided here, which is not shown in more detail.

As can be seen in particular from Fig. 4, the mode of operation of the device is as follows:

A piece of goods, e.g. a package 9, is transported via a feed track

10 of the device 1. The package, a transport basket or the like, is equipped with a code that is read by a scanner, a light barrier or the like, in Fig. 4 with

11, the information is fed to a computer system 12, which in turn controls the underfloor servomotors of the turntables 3, for example in such a way that they move to the right, as indicated in Fig. 4, in order to move the package 9 sideways onto a right-hand adjacent roller conveyor 13, the driven rollers of which then move the package 9 onto a further conveying means, e.g. a belt 14.

If the turntables 3 are pivoted to the left, the left roller conveyor 13b and thus the further conveyor 14b are acted upon, which is not shown in more detail.

A distribution to the right-hand conveyor 14, the middle conveyor 14a or the left-hand conveyor 14b can be seen, each with reference to Fig. 4, in

·

Throughput possible/ there is no stopping or halting of the packages or object distribution from the feed track C to the further conveyors 14, 14a or 14b.

As can be seen in particular from Fig. 4, the further roller conveyors arranged laterally next to the device 1 are equipped with driven rollers 15, which are arranged at a slight outward angle relative to the feed direction 5, the angular position of the rollers 15 being smaller than the angle of attack of the turntables 3.

Of course, the described embodiments of the invention can be modified in many ways without abandoning the basic idea. For example, a first device according to the invention can also have additional distribution turntables assigned to the right and left side continuation positions, and so on.
