[0001]. Field of the invention
[0002]. The present invention relates to a roller, as well as to a roller conveyor, as well as to a roller maintenance method, a method for managing a roller conveyor, and a method for managing a plurality of roller conveyors.
[0003]. Background art
[0004]. Roller conveyors are known among the systems for moving loads and goods.
[0005]. Roller conveyors usually comprise a support frame onto which there are connected at least one motorized roller or motoroiler or motor, a plurality of idle rollers, a plurality of driven rollers, and a motion transmission system, e.g., at least one transmission belt or chain, which allows transferring the motion from said at least one motorized roller, directly or indirectly, to the plurality of driven rollers by means of said at least one belt or chain.
[0006]. In particular, the motorized roller or motoroiler comprises a hollow cylinder, in which a motor is arranged, which allows rotating the hollow cylinder with respect to the frame by means of an already known transmission system.
[0007]. In some known solutions, the motorized roller comprises a motorized roller transmission member, such as a pulley, for example, adapted to transmit the motion to the adjacent members or rollers and firmly constrained, under rotation, to the hollow cylinder. Each driven roller comprises a driven roller tube which is rotatable with respect to the frame and a respective driven roller transmission member, such as a pulley, for example, firmly constrained, under rotation, to the driven roller tube. The motorized roller transmission member is directly connected at least to the driven roller transmission member, for example by means of a transmission belt so as to directly transfer the motion of the motorized roller to the driven roller.
[0008]. As known, idle rollers are mounted to the frame of the roller conveyor and are configured to slide goods or loads moved by a motorized roller or a driven roller. Each idle roller comprises an idle roller tube which is rotatable with respect to the frame without being connected to the motorized roller or to other driven rollers.
[0009]. In order for the roller conveyors to operate correctly, the transmission members and the transmission belts connecting them must be carefully positioned so as to correctly transmit the motion from the motorized roller to the driven rollers, and further allow the correct movement of the loads on the idle rollers, without damaging the motor of the motorized roller and the transmission belts.
[0010]. It should be noted that the roller conveyors of the known type, once installed, if a position replacement of a driven roller or an idle roller with a motorized roller is needed, for example to slow down or speed up the pieces/goods in specific points of the roller conveyor where motorized rollers were not included, it is necessary to stop the roller conveyor, at least partially disassemble the transmission system, separate the motorized roller to be displaced from the frame, separate the driven roller or idle roller to be displaced from the frame, invert the positions of the motorized roller and the driven roller or idle roller, reassemble the transmission system, and calibrate it correctly. Such operations are highly complex and very time consuming in terms of intervention. [0011]. Furthermore, in case of maintenance or faults with a motorized roller, the roller conveyor must be stopped and the motorized roller must be separated from the frame, fixed, or replaced with a replacement motorized roller.
[0012]. According to some solutions, whenever a motorized roller is separated from the roller conveyor, it is necessary to disassemble at least partially and simultaneously the motion transmission system, i.e., disconnect at least the transmission belts connecting the motorized roller to the first close driven rollers and separate such first close driven rollers from the frame to create enough space to remove the motorized roller.
[0013]. Therefore, the operations of maintenance or replacement of the rollers, and in particular of the motorized rollers, imply a considerable expenditure of time, labor, and skills required to remove not only the drive roller, but also at least some components of the first close driven rollers, and to remove the transmission belts connecting them to the motorized roller. Furthermore, whenever a motorized roller is replaced with a new one, it is necessary to correctly position the transmission members of the new motorized roller and the first close driven rollers, and position the transmission belts correctly, by pre-stressing them, which operations are particularly time consuming in terms of work.
[0014]. Therefore, a need is strongly felt in the field to reduce, as much as possible, machine stoppages in case of programed maintenance and special maintenance.
[0015]. In particular, the need is strongly felt to reduce machine stoppage times and conceive technical solutions which allow replacing the motor of a motorized roller, intervening as little as possible and in as short a time as possible, on the kinematic connection chain between the motorized roller and the driven rollers, so that it does not need to be positioned and calibrated whenever a motor is replaced or maintenance is carried out on a motorized roller.
[0016]. Furthermore, it is known that in some cases, a plurality of roller conveyors is present inside the same production plant, with rollers having axial roller extensions, i.e., different roller lengths along an axial direction about which the roller rotates, depending on the dimensions of the loads/goods to be conveyed. For example, the plurality of roller conveyors comprises a first roller conveyor with rollers having a first roller length, and a second roller conveyor with rollers having a second roller length.
[0017]. Therefore, in such plants, it is necessary to keep different rollers in the warehouse having different lengths for each of the plurality of roller conveyors so as to quickly replace the rollers if a fault occurs and to minimize the duration of the machine stoppages. Therefore, it is necessary to provide warehouses with adequate dimensions and a correct planning of the stockpiles in the warehouse, which activities can be particularly expensive. Furthermore, if sufficient pieces are not present in the warehouse, it is necessary to order the production of new replacement rollers, which can have lengthy delivery times, thus significantly impacting on the duration of the machine stoppages of the roller conveyor.
[0018]. Therefore, the need is strongly felt to increase the modification versatility of a roller conveyor, reducing the machine stoppage and the intervention times.
[0019]. Furthermore, the need is strongly felt to reduce the warehouse costs, while reducing the times for ordering and retrieving new rollers, not present in the warehouse.
[0020]. Therefore, the problem underlying the present invention is the development of a roller and a roller conveyor which have such structural and functional features to meet the aforesaid needs, while obviating the drawbacks mentioned with reference to the prior art and meeting the aforesaid needs.
[0021]. Solution
[0022]. It is the object of the present invention to provide a roller, a roller conveyor, a plurality of roller conveyors, a roller maintenance method, a method for managing a roller conveyor, and a method for managing a plurality of roller conveyors. [0023]. These and other objects and advantages are achieved by a roller according to claim 1, as well as a roller conveyor according to claim 32, as well as a plurality of roller conveyors according to claim 35, as well as a roller maintenance method according to claim 36, as well as a method for managing a roller conveyor according to claim 39, and a method for managing a plurality of roller conveyors according to claim 40.
[0024]. Some advantageous embodiments are the subject of the dependent claims.
[0025]. From an analysis of this solution, it has emerged how the suggested solution allows carrying out maintenance activities on motorized rollers, or driven rollers, or idle rollers with significantly shorter times than the solutions of the prior art, thus it allows a reduction in the duration of the machine stoppages necessary for the maintenance of a motorized roller, or a driven roller, or an idle roller, and in particular a reduction in the intervention operations on the kinematic connection chain between motorized rollers and driven rollers.
[0026]. Furthermore, the suggested solution allows separating a first roller portion, without intervening and/or stressing a second roller portion which can remain connected to a frame of a roller conveyor.
[0027]. Where the second roller portion comprises a transmission member, it is possible to reduce the times required for the maintenance of a roller without needing to intervene, at least partially, on the transmission system of the roller conveyor. [0028]. According to some solutions, the first roller portion comprises a motor adapted to rotate the roller, allowing a reduction in the maintenance times of a motorized roller, replacing the first roller portion without intervening on or stressing the second roller part.
[0029]. Furthermore, the suggested solutions allow increasing the reliability and versatility of the roller conveyors and allow a drastic reduction in machine stoppages.
[0030]. Still further, the suggested solutions allow the owner of a roller conveyor to standardize the first roller portion, in particular by fixing an axial first roller portion extension, independently of the total length of the roller to be mounted to a specific roller conveyor, thus allowing the use of the same first roller portion with a plurality of second roller portions having customized axial lengths, thus optimizing the necessary spare parts.
