Abstract

An apparatus for conveying and storing objects arranged in a hanging manner has conveying sections, storage sections running perpendicularly thereto and driven conveying trucks for the objects, which trucks can be moved on the conveying sections. The objects are arranged in a hanging manner on slides which can be connected to the conveying trucks and can be displaced on roller tracks and which, by means of dogs, can be brought positively into engagement with driven, endless toothed belts and, by this means, can be displaced. Such roller tracks and toothed belts are arranged both on the conveyor trucks and on the storage sections. Stop means are used to bring the dogs out of engagement with the toothed belts in order, in this way, to release the driving connection between the slides and the toothed belt.

Description:

Device for conveying and storing suspended objects

The invention relates to a device for conveying and storing suspended objects Conveyor lines, storage lines running transversely to them and with driven ones running on the conveyor lines Trolley for the objects.

In known devices of this type, the trolleys are on their rails, for example by driven chains with which the car can be temporarily connected positively. The to Objects to be transported and stored are attached directly to the trolleys. The trams with the objects hanging on it are removed from the conveyor lines They are directed via remote-controlled switches to the storage sections, where they remain until they are returned when needed can be accessed. In this device, the trolleys can at least on the storage routes only in a single Direction, which is often a disadvantage. Another disadvantage is that the necessary switches make the device as a whole complex and prone to failure. Finally, the stored on the storage lines can Trolleys are not used for other purposes, in particular for transport on the conveyor lines.

FIG. 1 shows a schematic plan view of a magazine for the automatic storage and retrieval of objects. The magazine is at least partially enclosed by a conveyor track 1, on which conveyor carriage 2 in the direction of the arrows P revolve. The remotely controllable trolleys 2 can be carried out individually in a manner known per se driven or, if necessary, movable by latching into a conveyor chain running parallel to the conveyor line 1. Between two branches 3, 4 of the conveyor line 1 running through in opposite directions from the trolley 2 are transverse branches Storage sections 5 are provided, which form the actual magazine for storing objects.

In a manner yet to be described, the objects to be stored are not directly attached to the trolley 2 but rather rather, it is suspended from the carriage 6, which in turn can be detachably connected to the trolley. The carriage 6 with the attached objects are from the trolley 2 in a manner also to be described on the Passed storage sections 5, where they are stored until later removal. After separating the slide 6 from trolley 2 this is immediately available again for further use. The storage sections 5 are shown in FIG partly still empty, partly filled with carriage 6. The suspension of an object 7 on a carriage 6 results from Figure 2, left. One or more preferably similar objects can be detachably attached to each slide 6 will.

In Figure 2 and 3 is the structural design of the conveyor lines 1, the trolley 2 and the storage lines 5 shown in principle. The conveyor lines consist of 8 on a ceiling running rails 11 fastened by means of supports 9.

The trolleys 2 are on with the help of rollers 12, 13 and 14 the running rail 11 is supported and by electric motor 15, dit. connected to rollers 12 in a conventional manner

driven. The rollers and the motors are attached to a conventional supporting structure surrounding the running rail 11, which merges into a frame-shaped support bracket 16 downwards. In the support bracket 16 is a driven by a further electric motor 17, guided over toothed rollers 18,19, on both sides Toothed toothed belt 21 is arranged, which extends transversely to the direction of travel (arrow P in Fig. 1) of the trolley. in the Tzagbügel 16 is also a roller conveyor for receiving and moving the carriage 6 is arranged. This roller conveyor comprises rollers 22 which support the carriage 6 from below and rollers 23 which engage laterally on the carriage 6.

Each storage section 5 also includes a roller conveyor, which is arranged in the same way as the roller conveyor in the trolley 2 Rolls 22 and 23 includes (see. Also FIG. 6, in which the mounting of these rollers on an angled profile rail 24 is shown is ^ l In further analogy to the trams are also within the storage sections 5 above the roller conveyors individually driven toothed belts 25,26 and 27 are provided, which together are attached to the roller tracks by support 28 on the ceiling 8 (Fig. 2).

The structural design of the slide 6 is shown in FIGS. 4, 5 and 6. On each carriage 6 is one down protruding and between the rollers 22 of the roller conveyors running through carrier 29 for hanging the goods 7 is fixedly arranged. The carriages 6 consist of a tube 31 of rectangular cross-section, on the lower and laterally located outer surfaces attack the rollers 22, 23 of the roller conveyors (Figs. 3 and 6).

For the positive connection of the carriage 6 with the toothed belts 21, 25, 26 and 27 arranged above the roller conveyors Provided on the upper sides of the slides facing the toothed belts are pivotable cams A1, A2, B1, B2, which in the In the manner evident from FIG. 4, each two adjacent teeth of a toothed belt, e.g., toothed belt 21, engage and thereby the entrainment of the carriage 6 by the leading one

Toothed belt 21 advances in the direction of arrow L (to the left in FIG. 4), presses the flank of the cam A2 engaging Tooth this against the weight of the projection 33 down into the interior of the tube 31, so that the toothed belt runs freely over the carriage 6 without taking it with you. In a corresponding manner, the cam A1 connected to the cam A2 by the connecting rod 34 also becomes ineffective made. If, on the other hand, the toothed belt 21 advances in the direction of arrow R (ie to the right in FIG. 4), the attempted The tooth flank acting on cam 2 is also the cam A2 to pivot upwards due to the torque exerted with respect to the pivot axis 32, but this is achieved by the Contact of the projection 33 on the lower inside of the tube 31 is impossible. As a result, remains in this Direction of travel of the toothed belt 21 in positive engagement with the cams A1, A2, so that the carriage 6 is carried along in Direction of arrow R is ensured.

In any case, the cams A1 and A2 are used exclusively to entrain the carriage 6 by the toothed belt in question in one direction (to the right), while the cams B1 and B2 only entrain in the opposite direction (to the left) ensure. On the other hand, as already mentioned, the spikes a prevent the one following on the left from being carried along Slide to the right, as cams A1, A2 are drawn in through the mandrels a. The spikes b prevent in corresponding Way, a sledge following from the right is taken along to the left, since the cams B1 and B2 are ineffective due to the spikes b be made.

This property of the cams and the mandrels cooperating with them as lifting means can be used for loading and unloading Emptying a storage section can be used practically in the following way:

In Fig. 1, 2 and 3 there is in the (left) trolley 2 a carriage 6 with an object 7 attached to it corresponding (remote-controlled) actuation of the toothed belts 21 and 25, the carriage 6 from the trolley 2 to the adjacent

Storage range 5 moved below tooth girder 25 will. By appropriate further actuation of the toothed belts 26 and 27, the slide can finally be attached to the opposite one The end of the storage section 5 can be transported, where it is returned by an empty trolley 2 (shown on the right in FIG. 1) can be picked up. When you pick up the toothed belts 2 7 of the storage section 5 and 21 of the trolley 2 in the appropriate Way operated.

If, as shown in FIG. under the toothed belts 26 and 27, the subsequent introduction of further slides from the left by actuating the Toothed belt 26 easily possible, since the cams of the carriage located under the toothed belt 26 and 27 in the previously described manner are all ineffective, .sodaß the toothed belt can be moved without the carriage located under it to take with you. In this way, the storage section 5 can be filled tightly with the carriage 6.

A carriage can be removed from a storage section 5 in both directions, that is to say also in FIGS. 1 and 2 to the left. In this case, only the toothed belts 21 and 25 need to be actuated accordingly.

With the help of the construction described, it is thus possible to use the same or the same carriage as desired in the opposite direction in the storage sections without back pressure to store and retrieve. This is a major advantage compared to conventional conveying and storage devices, because there a conveyance of the storage material in the storage sections only was possible in one direction and under considerable back pressure.

In FIG. 1, only one level of a magazine with storage sections 5 located in this level is shown. Storage lines 5 can of course be provided one above the other in different levels of the magazine. In this case
