Abstract

Disclosed is a conveyor roller (1) which comprises a shaft (2), a roller body (3) which is mounted such that it can be rotated about the shaft (2), and a protective cap (4). The protective cap (4) has a disk-shaped first section (5) for covering the interior of the roller body (3), which is arranged fixedly with respect to the shaft (2) and is oriented normally with respect thereto, and a channel-like or roof-like second section (6) which is arranged obliquely with respect to the shaft (2) and runs over a part length of the roller body (3) such that it is spaced apart radially from the latter. Furthermore, a conveyor system (12) with a conveyor roller (1) is disclosed, in which conveyor system a connecting cable (7) of the conveyor roller (1) is run in a curve or a loop to an electrical interface (8, 17) with a connector box (15) of the conveyor system (12), wherein the lowest point of the curve/the loop is located below said interface (8, 17).

Claims

1. Conveyor roller (1), comprising a shaft (2) and a roller body (3) mounted so as to be rotatable about the shaft (2), a motor for driving the roller body (3) disposed in the roller body (3) and a protective cap (4), which protective cap (4) comprises a disk-shaped first portion (5) for covering the interior of the roller body (3), which is disposed fixedly relative to the shaft (2) and oriented normally thereto, wherein

a connecting cable (7) is provided, which is connected to the motor by a first end and is threaded through an orifice provided in the protective cap (4), and

a channel-like or roof-like second section (6) comprising the protective cap (4) is disposed at an angle with respect to the shaft (2) and extends across a part length of the roller body (3) spaced radially at a distance apart therefrom and the second section (6) comprises a laying device and/or fixing device, in particular a groove (9), in which the connecting cable (7) is laid/fixed.

2. Conveyor roller (1) according to claim 1, wherein the second section (6) extends underneath the roller body (3) when the conveyor roller (1) is in a mounted position.

3. Conveyor roller (1) according to claim 1, wherein the laying device and/or fixing device is disposed on the bottom of the second section (6), and in particular the groove (9) is open towards the bottom when the conveyor roller (1) is in the mounted position.

4. Conveyor system (12), comprising a conveyor roller (1) according to claim 1, comprising

two frame profiles (13) extending at a distance apart between which the conveyor roller (1) is disposed,

a power supply and/or data line (14) running along a frame profile (13), and

a connector box (15) disposed on the frame profile (13) which is electrically connected to the power supply and/or data line (14) and to the connecting cable (7) of the conveyor roller (1).

5. Conveyor system (12) according to claim 4, wherein an electrical interface (8, 17) between the connecting cable (7) and connector box (15) is disposed underneath the channel-like or roof-like second section (6) of the protective cap (4).

6. Conveyor system (12) according to claim 5, wherein the electrical interface (8, 17) between the connecting cable (7) and connector box (15) is provided in the form of a plug and socket connection.

7. Conveyor system (12) according to claim 4, wherein the connector box (15) has a roof-like projection (16) and the electrical interface (8, 17) between the connecting cable (7) and connector box (15) is disposed underneath said projection (16).

8. Conveyor system (12) according to claim 7, wherein said projection (16) of the connector box (15) is disposed underneath the channel-like or roof-like second section (6) of the protective cap (4).

9. Conveyor system (12) according to claim 4, wherein the connecting cable (7) is run in a curve or a loop to the electrical interface (8, 17) of the connector box (15) and lowest point of the curve/loop lies underneath said interface (8, 17).

10. Conveyor system (12), comprising

a conveyor roller (1) having a shaft, a roller body (3) mounted so as to be rotatable about the shaft (2), a motor for driving the roller body (3) disposed in the roller body (3), a protective cap (4) and a connecting cable (7) running out of the roller body (3) and electrically connected to the motor, and the protective cap (4) comprises a disk-shaped first section (5) for covering an interior of the roller body (3), which is disposed fixedly relative to the shaft (2) and oriented normally thereto, and a channel-like or roof-like second section (6) which is disposed at an angle with respect to the shaft (2) and extends across a part length of the roller body (3) spaced radially at a distance apart therefrom,

two frame profiles (13) extending at a distance apart between which the conveyor roller (1) is disposed,

a power supply and/or data line (14) running along a frame profile (13) and

a connector box (15) disposed on the frame profile (13) which is electrically connected to the power supply and/or data line (14) and to the connecting cable (7), and which is disposed underneath the roof-like second portion (6) of the protective cap (4),

the connecting cable (7) is provided with a plug (8) or socket (17) at one end and the connecting cable (7) is run in a curve or a loop to a socket (17) or a plug (8) on the connector box (15), and the plug/socket connection forms an electrical interface (8, 17), and a lowest point of the curve/loop lies underneath said interface (8, 17) wherein the connector box (15) comprises a roof-like projection (16) and the electrical interface (8, 17) between the connecting cable (7) and connector box (5) is disposed underneath the roof-like projection.
