[0002] The present invention ha mo relates to a roller having a data cartridge.

Background Art

[0003] Background technology

[0004] Roller conveyors are known among systems for moving cargo and articles.

[0005] A roller conveyor generally comprises a support frame to which at least one electric roller or motorized roller, a plurality of idler rollers and / or a plurality of driven rollers are connected, and a motion transmission system, for example at least one transmission belt or chain, wherein the means of said at least one belt or chain enables the motion from said at least one electric roller to be transmitted directly or indirectly to the plurality of driven rollers.

[0006] In particular, an electric roller or motorized roller has a hollow cylinder in which a motor is arranged, enabling the hollow cylinder to rotate relative to the frame.

[0007] In some known solutions, the motor is arranged in the hollow cylinder so as to transmit driving torque by frictional coupling. Some solutions of this type are known from EP1656312B1, DE10200609327A1 , DE102016112051, WO2013 / 000006 e WO2016 / 141396 .

[0008] Such solutions assume the use of gaskets or contacts that function by friction to transmit operating torque or rotational torque from the motor to the inner diameter of the roller cylinder or motor-roller cylinder. Since such gaskets have or are made of elastomers, they can lose their effectiveness when they function by friction, damaging the transmission from the motor to the roller cylinder or motor-roller cylinder, i.e., the effectiveness of the transmission from the motor roller to the drive roller is reduced, if not offset. Furthermore, the deterioration of the gasket's effectiveness over time reduces the control of the material being conveyed by the roller conveyor, posing a potential danger to the material being conveyed and to all persons near the roller conveyor. Therefore, in order to overcome the deterioration of such gasket effectiveness, it is necessary to replace the motor from the roller cylinder, even if it is still operational, in order to restore normal transmission of operation from the motor to the roller cylinder. Such work is a significant time consumption in terms of machine downtime and consequently results in economic losses.

[0009] Therefore, a very strong demand in this field is to provide a system for transmitting motion from a motor to a roller cylinder that is effective and innovative compared to prior art, and to reduce the time and cost caused by machine downtime as much as possible.

[0010] In particular, a very strong demand is for a technical solution that would limit motor-related work to routine maintenance and any motor failures as much as possible, thereby significantly reducing the instances in which the motor needs to be removed from the roller.

[0011] Furthermore, there is a very strong demand for the manufacture of motor cartridges that are designed to be inserted into rollers and maintain high operational reliability.

[0012] Therefore, the fundamental objective of the present invention is to devise a roller having structural and functional features that satisfy the aforementioned requirements while simultaneously solving the aforementioned drawbacks by referring to the prior art, thereby satisfying the aforementioned perceived requirements. [Overview of the Initiative]

[0013] solution

[0014] The present invention presents a motor cartridge for rollers and a roller having structural and functional features that satisfy the aforementioned requirements while simultaneously solving the aforementioned drawbacks by referring to the prior art and satisfying the aforementioned perceived requirements.

[0015] This and other purposes and benefits are , request request 1 Related Law Ra Therefore, it is achieved.

[0016] Several advantageous embodiments are subject to dependent claims.

[0017] Analysis of this situation reveals that the proposed solution reduces the likelihood of motor cartridge failure, thereby reducing machine downtime, and demonstrates how it enables the manufacture of end-consumer motor cartridges consisting of a single component compared to prior art.

[0018] Furthermore, the proposed solution makes it possible to manufacture motor cartridges that are self-supported at only one end of the cartridge body.

[0019] According to some solutions, the motor cartridge assumes a single bearing that supports the stator of the motor unit internally and the rotor or gear motor of the motor unit externally, through which the driving torque can be transmitted to the rollers and simultaneously support the rollers, the motor unit, and the cartridge body.

[0020] In addition, the proposed solution makes it possible to increase the reliability and versatility of an electric roller provided with a motor cartridge, and to significantly reduce machine downtime. [BRIEF DESCRIPTION OF THE DRAWINGS]
