Description

[0001] Drive arrangement for a conveyor device

[0002] The invention relates to a drive arrangement for a conveyor device, a conveyor device comprising such a drive arrangement and a method for removing and inserting a drum motor from or into such a conveyor device.

[0003] Conveying devices in the form of belt conveyors or belt conveyors are known from the prior art, on which objects can be transported on a moving conveyor belt or belt. The conveyor belt is usually driven by a drive unit comprising a drive motor that transmits torque to the conveyor belt in the area of ​​a deflection pulley. Gear motors or drum motors located outside the pulley are usually used as drive motors.

[0004] In the event of a drum motor repair or replacement, unlike geared motors, the conveyor belt usually has to be opened or removed, as conventional drum motors are permanently installed in the belt conveyor. This results in lengthy setup times, as the conveyor belt must be reinstalled and tensioned after removal.

[0005] The invention is therefore based on the object of providing a drum motor for a belt conveyor which can be repaired in a simple manner.

[0006] The object according to the invention is achieved by a drive arrangement for a conveyor device, comprising a drum motor and comprising a receiving device for receiving the drum motor, wherein the receiving device is designed to transmit a torque from the drum motor to a conveyor belt of the conveyor device and wherein the drum motor is detachably fastened in the receiving device.

[0007] The conveyor device is, in particular, a belt conveyor or a band conveyor. The receiving device advantageously makes it possible to design the drum motor so that it can be replaced or detached from the conveyor device without having to remove or detach a conveyor belt of the conveyor device, since the torque transmission and thus the driving contact between the drive arrangement and the conveyor belt is realized via the receiving device.

[0008] Preferably, the receiving device is arranged in the conveyor device in a non-detachable manner. When the drum motor is detached from the receiving device, the receiving device preferably remains in the conveyor device.

[0009] Accordingly, the receiving device is preferably designed such that the conveyor belt can be arranged on the receiving device in a tensionable manner. In this case, the tension of the conveyor belt is absorbed exclusively by the receiving device and not by the drum motor.

[0010] The drum motor preferably has a housing. In this case, the housing is in particular not the receiving device. A housing of the drum motor is preferably also releasably received in the receiving device, in particular together with the drum motor. The drum motor can preferably be attached to the receiving device on the housing. For example, the housing of the drum motor can be a rotor or part of the rotor of the drum motor. Accordingly, the receiving device is not part of the rotor of the drum motor.

[0011] Furthermore, it is preferably possible for an outer element of the drum motor, for example an outer or surrounding tube, via which the torque was previously transmitted to the conveyor belt in known drum motors, to be omitted and for the drum motor to be connected to the receiving device via at least one internal component, for example a gear or gear element or a motor component. The connection between the internal component and the receiving device is made in particular in the manner described below. In particular, the internal component can be connected to the receiving device in a force-fitting or form-fitting manner, for example via the engagement elements and receiving recesses described below.

[0012] In order to drive the conveyor belt, the torque is transmitted from the drum motor to the conveyor belt via the receiving device, wherein the torque is transmitted from the drum motor to the receiving device and / or the torque is transmitted from the receiving device to the conveyor belt directly or indirectly, for example via gear elements.

[0013] Preferably, the receiving device is designed to be rotatable, with the receiving device and the drum motor sharing a common axis of rotation. In particular, the receiving device is arranged concentrically with the drum motor or the rotor of the drum motor. During operation of the conveyor device or the drive arrangement, the drum motor and the receiving device rotate, in particular, at the same angular velocity.

[0014] The receiving device is arranged in particular between the drum motor and the conveyor belt.

[0015] Preferably, the torque transmission from the drum motor to the conveyor belt occurs exclusively indirectly via the receiving device. In other words, there is no direct mechanical or drive connection between the drum motor or its rotor and the conveyor belt. The receiving device therefore represents, in particular, a gear for the drum motor.

[0016] Preferably, the drum motor is arranged in the drive assembly such that, when the drive assembly is installed in the conveyor device, the drum motor does not contact the conveyor belt. In particular, the rotor of the drum motor does not contact the conveyor belt.

[0017] The drum motor is preferably connected to the receiving device in a form-fitting manner to transmit the torque. Alternatively, the torque can be transmitted non-positively. The form-fitting or non-positive connection preferably occurs exclusively in the circumferential direction and, viewed in the radial direction, with respect to the drum motor or its rotor. Preferably, there is no form-fitting or non-positive connection in the axial direction with respect to the connection between the drum motor and the receiving device. This advantageously allows the drum motor to be removed from the receiving device and inserted or pushed in in the axial direction. Axial fixation is preferably also possible, as described below.

[0018] Preferably, the torque is transmitted to the conveyor belt via an outer circumferential surface of the receiving device. The outer circumferential surface of the receiving device contacts the conveyor belt, in particular directly or indirectly. The torque is transmitted, in particular, by positive locking or frictional locking. Preferably, the outer circumferential surface of the receiving device is therefore designed identically to an outer circumferential surface of known drum motors, so that the outer circumferential surface can drive the conveyor belt in the same way as previously achieved by a drum motor. Thus, the drive arrangement can advantageously be used in the same way as conventional drum motors and is therefore also suitable as a retrofit solution.

[0019] Preferably, the receiving device is rotatable exclusively via the drum motor and the drive arrangement does not comprise any further drive devices for driving the receiving device.

[0020] Preferably, an outer circumferential surface is configured for torque transmission by frictional engagement or positive engagement with the conveyor belt, wherein the outer circumferential surface preferably has a surface comprising plastic, in particular rubber, and / or wherein the surface has a structure. The structure is configured in particular for engagement with the conveyor belt.

[0021] Furthermore, one or more sprockets, for example two, three, four, five, or more, can preferably be formed on the outer circumferential surface of the receiving device, in particular axially evenly spaced, for engagement with a conveyor belt, which is designed as a modular belt or link belt. The sprocket is formed in particular by teeth arranged along the circumference, which form a sprocket due to the essentially round cross-sectional shape of the receiving device.

[0022] Preferably, the receiving device essentially completely surrounds an outer circumferential surface of the drum motor. This applies in particular when viewed in the circumferential direction. When viewed in the axial direction, the drum motor can be arranged partially or completely within the receiving device. For example, axial end regions of the drum motor can protrude from the receiving device.

[0023] The receiving device is preferably sleeve-shaped. A rotational axis of the receiving device preferably corresponds to a central axis of the sleeve. The drum motor is arranged in particular within the sleeve, so that a lateral surface of the sleeve surrounds the outer circumferential surface of the drum motor.

[0024] The sleeve shape can preferably be a cylinder or a prima.

[0025] A radial cross-section of the receiving device can be round, annular, or polygonal. In particular, an inner and / or outer circumferential surface is essentially circular or polygonal when viewed in cross-section, preferably with the exception of engagement elements or engagement structures for torque transmission, which will be described below.

[0026] Preferably, the radial cross-sections of the inner and outer circumferential surfaces can be different. For example, a radial cross-section of the outer circumferential surface can be round, while a radial cross-section of the inner circumferential surface is polygonal, or vice versa.

[0027] Preferably, the drum motor can be inserted axially into the receiving device via an axial end-side receiving opening of the receiving device. The receiving device can preferably have one or two axial end-side receiving openings. If the receiving device is sleeve-shaped, one or both of the circular end surfaces of the sleeve form the receiving openings. Furthermore, the receiving device can have a receiving opening at each of the axial end regions, so that the drum motor can be removed from the receiving device from both sides. Alternatively, the receiving device can be closed at one axial end region.

[0028] Preferably, the drum motor can be inserted into the receiving device in such a way that, during insertion, a positive connection is established between the receiving device and the drum motor, at least in some areas. In particular, this results in engagement of the drum motor with the receiving device, or vice versa.

[0029] Preferably, the receiving device is connected to the drum motor in the region of the outer circumferential surface of the drum motor. The outer circumferential surface of the drum motor is formed in particular by the rotor.

[0030] Preferably, at least one receiving recess is arranged on the drum motor or on the receiving device for transmitting torque from the drum motor to the receiving device, with an engagement element for engaging in the receiving recess being arranged on the other of the drum motor and the receiving device. The engagement is effected in particular in such a way that the drum motor is fixed relative to the receiving device, in particular exclusively, in the radial direction and in the circumferential direction.

[0034] The fastening element preferably comprises plastic or is made of plastic. This advantageously allows the fastening element to be manufactured in a simple manner, and in particular, the receiving recess or the engagement element can be formed in a simple manner, for example, by producing the fastening element using an injection molding process.

[0035] Preferably, the fastening element is arranged on an inner circumferential surface of the receiving device or in an outer circumferential surface of the drum motor.

[0036] Preferably, a fastening element is provided for each engagement element or each receiving recess. Alternatively, several engagement elements or receiving recesses can be grouped in a common fastening element, or all engagement elements or receiving recesses can be arranged in a single fastening element.

[0037] Preferably, the receiving recess and the engagement element extend parallel to the rotational axis of the drum motor. This advantageously allows a positive connection between the receiving device and the drum motor to be achieved by axially inserting the drum motor into the receiving device.

[0038] Preferably, the receiving recess and / or the engagement element extend partially or completely over an axial length of the drum motor.

[0039] Preferably, the at least one receiving recess is a groove, and the engagement element is preferably a spring or a key.

[0076] Figures 1 and 2 show perspective views of a conveyor device 200 comprising a conveyor belt 201, which is accommodated in a frame 201. A drive arrangement 100 is provided for driving the conveyor belt 201, which is arranged on a side facing away from a support surface of the conveyor belt 201.

[0077] The drive arrangement 100 has a drum motor 10, which is arranged in a receiving device 11. The receiving device 11 is designed to transmit torque from the drum motor 10 to the conveyor belt 201. The drum motor 10 is detachably arranged in the receiving device 11. The drum motor 10 can be pulled out of the receiving device 11 and pushed back in again along its axial extent A, as indicated by the arrows in Figures 1 and 2. As can be seen in Figures 1 and 2, only the drum motor 10 is removed, for example for repair or maintenance purposes, while the receiving device 11 remains in the conveyor device 200. This advantageously eliminates the need to open the conveyor belt 201, so that it can remain taut, in particular.

[0078] Figure 3 shows the receiving device 11, which has the shape of a cylindrical sleeve. The receiving device 11 has an outer peripheral surface 12a, an inner peripheral surface 12b, and two axial end regions 13a, 13b. The receiving device 11 is open in the two axial end regions 13a, 13b, so that the end regions 13a, 13b represent openings through which the drum motor 10 can be inserted into the receiving device 11. Furthermore, the receiving device 11 has a plurality of fastening holes in the region of its peripheral surface 12 for attaching a fastening element 19, which is shown, for example, in Figure 6.

[0079] Figure 4 shows the drum motor 10 in a perspective view. The drum motor 10 also has a substantially cylindrical shape, wherein the drum motor 10 is shaped such that it can be arranged with a substantially precise fit within the sleeve-shaped receiving device 11, except for a small gap in which the engagement components of the drum motor 10 and the receiving device 11 are arranged. Accordingly, the drum motor 10 has an outer circumferential surface 14. Three engagement elements 17 are arranged, evenly distributed in the circumferential direction over the outer circumferential surface 14. The engagement elements 17 are designed as feather keys, which extend in the axial direction between two axial end regions 15a, 15b of the drum motor 10.Furthermore, stator ends 16 are provided in the axial end regions 15a, 15b, by means of which the drum motor 10 is mounted in the conveyor device 200, as will be explained below with reference to Figures 7 and 8.

[0080] Figure 5 shows a cross-sectional view through the drive assembly 100. It shows the drum motor 10, which is arranged within the receiving device 11. Furthermore, the drum motor 10 is attached to the receiving device 11, so that torque can be transmitted from the drum motor 10 via the receiving device 11 to the conveyor belt 201. For this purpose, the engagement elements 17 of the drum motor 10 engage in receiving recesses 18 of the receiving device 11.

[0081] The receiving recesses 18 are each formed in a separate fastening element 19, wherein the fastening elements 19 are fastened to the receiving device 11 on its inner circumferential surface 12b, for example, by means of a screw connection. The fastening elements 19 are designed as fastening projections and as separate components made of plastic.

[0082] Figure 6 shows a fastening element 19, wherein the receiving recess 18, which is designed as a groove, is illustrated, as well as several through-openings for screwing the fastening element 19 to the receiving device 11. Figures 7 and 8 show a first bearing device 20 for supporting the drum motor 10 in the conveyor device 200. The bearing device 20 comprises a first bearing element, which is constructed in two parts from a first bearing element component 21a and a second bearing element component 21b. The first bearing element component 21a and the second bearing element component 21b together form a bearing plate. The first bearing device 20 can comprise a second bearing element at the second axial end region 16 of the drum motor 10.

[0083] The first bearing element component 21a and the second bearing element component 21b each have a semicircular recess which, when the two bearing element components 21a, 21b are assembled, forms an opening for receiving or supporting one of the stator ends 16 of the drum motor 10. To remove the drum motor 10, the first bearing element component 21a can be removed first, as shown in Figure 9, and then the second bearing element component 21b. The bearing element components 21a, 21b are fastened to a central fastening element 23 by means of a screw connection. The central fastening element 23 is in turn fastened to the conveyor device 200 or the frame 202 by means of several screw connections.

[0084] The central fastening element 23 is plate-shaped and further serves to accommodate a second bearing device 24 for mounting the receiving device 11 on the conveyor device 200, as shown in Figure 9. The second bearing device 24 comprises several, here four, second bearing elements 24a to 24d, which are designed as roller bearings. The bearing elements 24a to 24d are arranged around the outer circumferential surface 12a of the receiving device 11, so that the outer circumferential surface 12 rolls over outer circumferential surfaces 25 of the second bearing elements 25 and the receiving device 11 is thus rotatably mounted in the conveyor device 200. Another similarly designed second bearing device 24 is arranged at the further axial end region of the receiving device 11.

[0085] Figure 10 shows a detailed representation of a second bearing element 24a to 24d, wherein on the one hand the outer circumferential surface 25 is shown as well as a radially projecting axial bearing surface 26, which is designed as a flange and axially abuts the end of the receiving device 11 and thus fixes the receiving device 11 with respect to its axial position.
