Definitions

  • the invention relates to a roller conveyor for conveying or positioning goods to be transported, with two side cheeks extending parallel in the conveying direction, between which roller elements with driven support rollers are arranged transversely and at a radial distance, which are non-rotatably coupled with at least one driving toothed pulley and takes the priority of the German one Patent application 199 63 430.0-22, to which reference is made in terms of content.
  • roller conveyor is described in German Offenlegungsschrift 41 26 822.
  • the roller elements each have an axis which is firmly screwed to the side walls on the end face.
  • Almost the entire length of the axle is enclosed by a support tube, which can be rotated by means of roller bearings and is fixed on the axle in the axial direction.
  • tubular drive elements are pushed in each case.
  • These drive elements are non-rotatably connected to the support tube with feather keys and tension rings. Snap rings ensure that the drive elements maintain their axial position on the support tube.
  • the outer ends of the drive elements have external toothing in which toothed belts transmitting the torque of a drive motor engage.
  • the idlers On the remaining length sections of the drive elements are the idlers, the internal teeth of which correspond to the corresponding external teeth of the drive elements intervene so that these parts are non-rotatably connected.
  • Flanges for the lateral guidance of the goods to be transported are arranged on a support roller on both end faces.
  • the idlers and flanged disks also hold snap rings that are inserted in the drive elements in their axial positions.
  • This roller conveyor has the major disadvantage that its production is very complex. This is partly due to the large number of individual parts and also due to their relatively complicated shapes. Multi-part clamping rings with wedge surfaces, internal and external toothing, parallel keys and parallel keyways as well as many grooves for snap rings must be made to size. The great outlay associated therewith causes correspondingly high production costs, in particular if such roller tracks have a large length, which requires many roller elements and correspondingly many individual parts. Because of the numerous components of each roller element, assembly is also particularly complex and therefore expensive. But not only the assembly, but also the disassembly is cumbersome, time-consuming and therefore also expensive.
  • Disassembly is important here because the moving parts of such roller conveyors - for example when transporting sharp-edged goods - are subject to considerable wear and tear and must therefore be replaced more often.
  • the known roller conveyor With the known roller conveyor, however, not only do high manufacturing, assembly and dismantling costs arise, but also long downtimes of the roller conveyor and thus the associated overall system.
  • Another disadvantage is the fact that in the known roller conveyor, the existing construction can only be adapted poorly and with great effort to other local conditions, to other track widths, other weights of the goods to be transported, other drives and the like.
  • the invention is based on the problem of creating a roller conveyor which is simple in design and manufacture, is easy to assemble or disassemble and can be adapted to different conditions.
  • This problem is solved according to the invention in that the roller elements in the side cheeks have rotatably mounted shafts, onto which the supporting rollers, the toothed disks and individual parts are pushed directly by them and coupled non-rotatably to the shafts by non-round shaft and bore cross sections and by means of shaft shoulders and / or releasable retaining rings are held axially.
  • roller conveyor that is particularly simple and can be produced with little effort.
  • the shafts replace the well-known axles that are firmly screwed to the side bolsters.
  • the idlers, toothed lock washers and a few other individual parts are arranged directly on the shafts. Since the shafts are rotatably mounted, the same applies to the idlers, toothed lock washers and other individual parts that are pushed onto the shafts without any additional storage effort.
  • the known support tubes and drive elements, but also other individual parts, are omitted. This eliminates their manufacture and the manufacturing costs of the roller conveyor decrease considerably.
  • each roller element also enables easy assembly and disassembly and thus quick replacement of individual wearing parts. Even converting existing roller conveyors, for example to other track widths and for other drives with other traction devices, is possible with little effort in many cases. The short downtimes of the entire system that can be achieved thereby keep the production failure during repairs and conversions is low. Finally, support rollers pushed directly onto the shafts mounted in the side walls simplify the discharge of electrical interference fields and electrostatic charges.
  • Each roller element need only have a rotatably mounted shaft onto which at least one toothed disc and at least two idler rollers arranged at an axial distance are pushed.
  • the idlers, toothed lock washers and individual parts can be arranged on their shaft in any order and can have any desired axial distance from one another. They are non-rotatably coupled to one another via the rotatable shaft and the peripheral speed of the idlers, which is important for perfect transport, is always maintained.
  • each roller element it is also possible for each roller element to have two or more rotatably mounted shafts which are rotatably supported with their mutually facing ends in intermediate cheeks extending between the side cheeks and parallel to these.
  • Such a design is particularly suitable for roller conveyors with a particularly large width.
  • the advantages according to the invention also result here and the support rollers, toothed lock washers and individual parts can be arranged in any way distributed on the shafts.
  • the shafts are supported at their ends in bearing housings which can be inserted in the radial direction in recesses in the side or intermediate cheeks.
  • the individual roller elements with all of their parts such as idlers, toothed disks, shafts and the bearing housings, can preferably be lifted upwards out of the recesses in the side or intermediate cheeks without expensive disassembly work.
  • the bearing housings, in which the shafts are expediently stored in roller bearings can be pulled off the shaft ends and then each part that is mounted on the shafts is pushed. It is quick and easy to replace individual or all parts.
  • the subsequent installation of modified or repaired roller elements can only be done without screwing them down simply by inserting them, preferably from above into the recesses in the side or intermediate cheeks, the roller elements being automatically aligned and centered.
  • An expedient embodiment consists in the fact that two support rollers of a roller element each consist of a bushing for carrying the goods to be transported and a flanged wheel as a side guide for the goods to be transported. Each idler roller then guides the goods to be conveyed on its side of the roller conveyor and prevents it from falling sideways there. It is advisable to arrange the flanged wheels of both idlers on different end faces of the idlers.
  • the flanged wheels can be designed as separate individual parts which, like the other parts, are pushed onto the shafts and coupled to them in a rotationally fixed manner.
  • one of the support rollers of a roller element has a flanged wheel on both end faces, and each additional support roller is merely designed as a bushing for carrying the goods to be transported.
  • each additional support roller is merely designed as a bushing for carrying the goods to be transported.
  • only one support roller of each roller element takes over the lateral guidance of the transport goods to both sides, for which purpose this should have a rail-like guide element on its underside.
  • skid frames which are used as assembly platforms in the assembly line production of motor vehicles and are moved with them over a roller conveyor.
  • the carrying rollers for carrying the goods to be transported have a bandage covering their circumferential surface, which has on at least one side a radially projecting wheel flange serving as a flanged wheel.
  • a bandage can also consist of a suitable plastic. This can be opened directly apply the idler. With such a bandage, separate flanged wheels and thus also other individual parts can be saved. Additional individual parts can be saved if the support rollers and the flanged wheels for the lateral guidance of the transported goods are made in one piece.

  • the flanged disc 9 is used to guide the goods to the side and, with its flat attachment 9a, also to reject the traction means.
  • the flanged disk 9 is designed as a separate part. In many cases, however, it is more advantageous to form the flanged wheel 9 in one piece with the support roller 8 shown on the left in FIG. 1 as a bushing, which is the case in FIG. 1 on the right for a second support roller 10 in the region of the side cheek 3. There, however, the toothed disc 7 is missing.
