Description

1 2707271

  The present invention relates to a device for the controlled guidance of objects, in particular containers, on or by a conveyor which is constituted by running rails comprising rollers arranged therein, the running rails being oriented in the rolling direction of the objects to be transported and the rollers of

  bearing perpendicular to the direction of travel of the objects to be transported, and the carrier being inclined in the rolling direction.

  Such carriers have a generally broad field of use. In addition, containers, crates,

  Cartons or the like to be transported are moved on freely rotating rollers. After the containers have been loaded onto the higher loading side of the trans-

  carrier, they move, under the action of gravity, on the rollers to the discharge side of the carrier, o the first container is stopped, for example by a stop, for the purpose of evacuation. The following containers accumulate behind the first container to be evacuated. For evacuation, the stop is lowered, whereby the container is released and the following containers are stopped,

  so that the simultaneous release of several containers is avoided.

  Such a device for the automatic evacuation of objects by a transporter is known, for example, from patent EP-0 398 349. The device comprises a pivotable rocker, which carries, at its outlet end, a device for stop

  for containers on a roller train. By pivoting the rocker, the stop device is lowered, so that the first container can be removed from the roller train.

  At the same time, an output device at the other end of the scale is raised, so that the following containers are prevented from moving. After evacuation of the container, the rocker pivots back to its initial position, so that the next container can be transported to the stop device at the end of the container.

roller train.

  In devices known from the state of the art, insofar as they are based on the principle of displacement by gravity, it can be disadvantageous that containers, because of the inclination of the carrier, stop during their transport on the conveyor or that the accumulated containers can not restart when they have been stopped by the stop in order to evacuate the first container. These disadvantages can not be

  avoided by optimizing the construction of the transpor-

  for example a special adjustment of the inclination of the conveyor, in particular when containers having different shapes and weights have to be transported. So,

  such a system can also be automated only difficult-

  because the disadvantages indicated can not be

palliated only manually.

  Accordingly, the purpose of the invention is to provide a

  for the controlled guidance of objects on or through

  carrier, in which the disadvantages indicated are avoided and, in particular, a controlled restart of the accumulated containers is possible through simple construction means. For this purpose, the device for the controlled guidance of objects, in particular containers, on or by a conveyor, of the type indicated above, is remarkable, according to the invention, in that, under the running rails, each time, a carriage is provided on which are provided, for

  influence the rotation of the rollers, the training elements

  and in that the carriage is movable horizontally, under the respective rolling rail, by means of a pulse mechanism, to bring the elements of driving and stopping in contact with the rollers or off contact thereof.

  Advantageously, the carriage is arranged in the area between the rollers and the bottom portion of the respective rail. In order to improve the guiding of the carriage, in a particular embodiment of the invention, the running rail is formed in the form of a U. The driving and stopping elements preferably consist of an elastic material, such as rubber or the like. By moving the carriage, the elastic driving and stopping elements can be brought into contact with the rollers on which the container (s) or the like are transported, whereby the rollers and thus the containers carried by them20 are trained. A stopping of the rolls is obtained when the driving and stopping element is moved across its width below the respective roller and is held there. Since the height of the driving and stopping elements according to the invention is slightly greater than the distance between the rolling rollers and the carriage, the driving and stopping element is at the contact, in a compressed state. If, after the evacuation process, the accumulated containers have to be restarted, the truck is moved again. This movement is transmitted, via the driving and stopping elements, onto the rollers, which are

driven in rotation.

  Due to the fact that, on the elongated carriage, a plurality of spaced-apart driving and stopping elements are arranged, which in each case come into contact with a rolling roller, the result is that the rotation of the rollers and, thus, the movement of the containers can be triggered at each point of the action zone

of the trolley, in a simple way.

  In a particular embodiment of the invention, the conveyor consists of two running rails, which run parallel to each other in the

  rolling direction of the object to be transported. naturally

  It is also conceivable to use more than two running rails. In addition, the number of running rails

  depends, for example, on the type of objects to be transported.

  The use of several running rails is particularly

  significant effect when objects of different

  shapes, sizes, and weights, must be transported.

  The trolley pulse mechanism is advantageously designed as a lever, which on the discharge side of the conveyor is articulated to the carriage and which is rotatably mounted about an axis of rotation provided on the outside of the carriage.

rolling track.

  To simplify the manipulation, the individual impulse mechanisms can be coupled to each other, according to the invention, to ensure a synchronous displacement of

  carriages in the respective tracks.

  In this way, it is guaranteed a simple manual manipulation of the device according to the invention. Moreover, such

  device can be automated without problems.

  Finally, the device of the invention can be used without problems in already existing systems, without these having to be modified, from a constructive point of view, in

a particular measure.

  The figures of the annexed drawing will make clear how

the invention can be realized.

  FIG. 1 is a perspective view from above of a partial zone of the device according to the invention in the vicinity of

  evacuation side of the carrier.

  FIG. 2 is a schematic side view of the device according to the invention in the vicinity of the discharge side of the

  carrier, along line I-I of Figure 1.

  FIG. 3 is a section of a running rail of the arrangement

  according to the invention along line II-II of FIG.

  With reference to FIG. 1, the conveyor 1 consists of two running rails 2, in which rollers 3 are arranged each time. The containers 4 to be transported (see FIG. 2) are put in place, on the loading side (not shown) of the conveyor 1, on the rollers 3 and move, due to

  the inclination of the transporter 1, under the action of gravity

  to the evacuation side.

  carrier 1 can be carried out either manually or by a

  conventional loading device (not shown).

  Under the rails 2, it is provided, each time,

  a carriage 6 on which training elements are arranged.

  and stop 7 spaced apart from each other. In the present example, the carriage 6 is made in the form of flat steel and the driving and stopping elements 7 in the form of skates

slip type rubber.

  As can be seen from Figures 2 and 3, the carriage 6 is arranged, with the driving and locking elements 7 therein, between the rollers 3 and the bottom portion 8 of the rail of 2. The carriage 6 can be moved horizontally in the running rail

  2 by means of a pulse mechanism 9.

  The driving and stopping elements 7 are distributed over the entire length of the carriage 6 and have a spacing from one another which corresponds to that of the rollers of

  bearing 3 or a multiple of it.

  The driving and stopping elements 7 have a height which is slightly larger than the distance A

  between the rollers 3 and the carriage 6.

  The respective carriages 6 of the individual running rails 2 are coupled to each other by a connecting element 10, to ensure the synchronous displacement of the carriages 6 in the running rails 2. This movement is effected via a lever 11, which is articulated, on the discharge side 5 of the conveyor 1, to the carriage 6. In the exemplary embodiment, the lever 11 according to FIG. 2 is connected to the carriage 6, but this can also be attached to the connecting element 10. The lever 11 is rotatably mounted outside the running rail 2 about a separate axis of rotation D. The lever can be adjusted manually or automatically via

  of a usual training (not shown).

  When a container 4 reaches the discharge side 5 of the conveyor 1, the respective carriage 6 is moved in the direction of the arrow B according to FIG. 2, horizontally, in the rails 2, when the lever is actuated. 11. The driving and stopping elements 7 on the carriage 6 come into contact with the

7 2707271

  rollers 3, whereby their rotation is influenced. First, the rotation of the rollers 3 and thus the movement of the containers 4 are braked. At the moment when the driving and stopping elements 7 are in contact with the rollers 3 over their whole width, the rotation of the rollers 3 is stopped, whereby the containers 4 go

  finding on carrier 1 stop. So, the

  in the area of the evacuation side 5 of the conveyor 1 can be evacuated. To rotate the rollers 3 again for the subsequent transport of the containers 4, after the evacuation, the carriages 6 are again moved in the running rails 2, until the driving and stopping elements 7 are brought out of contact with the rolling rollers 3. By moving the driving and stopping elements 7 below the rollers 3, a rotation is imposed on them. As a result, the containers 4 on the rollers 3 are again activated to continue their path on the conveyor 1 under the action of gravity, until the next container 4

reach the evacuation side 5.

  The subsequent return of the carriages can be carried out, for example, by means of a return device (no

  shown) or by means of springs.
