Definitions
- the invention relates to a roller conveyor for piece goods with two side supports and with a plurality of cylindrical support rollers, which are arranged a substantially horizontal conveying plane for the cargo rotatably between the side supports and stored or suspended end in the side supports.
- the invention further relates to a casting casting machine for castings with such a roller conveyor.
- Roller conveyors of the kind in question are known from the prior art, including, for example, the patents DE 43 09 222 A1, GB 1, 118,846 A and US 4,325,473 A.
- roller conveyors known from the prior art are exposed to heavy wear, in particular in the case of heavy and / or angular general cargo. Furthermore, there is sometimes a considerable amount of noise.
- the invention has for its object to provide a roller conveyor of the kind in question, which does not have at least one associated with the prior art disadvantage or at least only to a reduced extent.
- roller conveyor according to the invention with the features of claim 1.
- the invention also extends to a cast-washing system comprising at least one roller conveyor according to the invention.
- the roller conveyor according to the invention is characterized in that it has at least one section or conveying section within which the carrying rollers are resiliently mounted or suspended in the side supports and thus can deflect away in the vertical direction down.
- the respective support sheets are not rigidly mounted on or in the side supports, but yielding, so that these support rollers, starting from a zero or initial position down, preferably only down, spring or . and then finally spring back to their original position.
- This spring movement is made possible only by a corresponding storage of otherwise rigid in itself support rollers.
- the spring-mounted or suspended carrying rollers can also be referred to as spring-loaded carrying rollers.
- the spring-mounted support rollers can, for example, be mounted in the side supports by means of end or end bearing journals (such as shown in GB 1, 1 18,846 A), wherein the journals in the side supports from below by means of springs, ie by at least a spring, for example.
- a coil spring and / or gas spring can be supported.
- the resilient support can be direct or indirect (eg. With the help of bearing elements, see below). The suspension and damping characteristics can be adjusted based on the springs used and thereby, for example, be adapted to the weight of the piece goods. Due to the resilient support on the bearing journal, the respective support rollers are biased upwards and are thereby held at no load in its initial position.
- the side members can, at least in the relevant section, be designed as a ladder-like frame, with an upper side rail, a lower side rail and rung-like between the upper side member and lower side member arranged vertical Stützträgem, wherein the springs for the resilient mounting of the support rollers are arranged in these vertical support beams ,
- the vertical support beams are preferably designed for this purpose as a hollow profile carrier. Due to the ladder-like side support, the roller conveyor is very stable and thus also suitable for large and / or heavy piece goods (eg castings, see below). The positioning of the springs inside the support beams allows a space-saving and protected arrangement.
- the spring-mounted support rollers can be supported by means of bearing elements (in the example.
- the bearing pins engage) in the support beams, wherein the bearing elements are longitudinally displaceable attached to the support beams and biased by arranged inside the support beams springs upwards.
- the support beams may, for example, be formed with vertical longitudinal grooves in which the bearing elements are guided.
- the bearing elements are made of light metal or plastic.
- the bearing elements on guide areas, with which they are attached to the support beams, eg. In the vertical longitudinal grooves, undercut and guided.
- the bearing elements can be formed with inside spring pockets in which the springs (preferably one spring each) are arranged or accommodated.
- a spring pocket creates space for the arrangement of at least one spring.
- End stops for the bearing elements are preferably provided, which limit their movement paths and thereby also the spring travel of the support rollers down. By the end stops to be prevented in particular that used as spring elements coil springs are compressed during compression to block length and thereby damaged.
- the conveying plane formed by the Tragroilen roller conveyor of the invention may have a slope, in particular a slight slope with an inclination of less than 2 °, and at least one formed with spring-loaded support rollers section which forms a stop or braking device for the cargo and which is located in particular at the end or before the end of the roller conveyor. If the piece goods reach the relevant section, they are stopped or at least braked by compression or sinking of the carrying rollers (stop or braking function). It also prevents the piece goods located in the section in question from rolling away in spite of inclines (holding function).
- the support rollers of the roller conveyor according to the invention at least the spring-mounted support rollers, in the axial direction continuous roller body.
- the support rollers or roller bodies thus have a cylindrical or roller-like shape.
- the axial length of the continuous roller body substantially corresponds to the width of the conveying plane.
- At least the spring-mounted support rollers or their roller body may have a sheath or a protective cover, for example.
- a sheath or a protective cover for example.
- Such sheathing or protective coatings are useful for sensitive cargo, eg. Castings with sealing surfaces, but can be easily damaged, the damaged support rollers then consequential damage to the cargo, for example. At the sensitive sealing surfaces of castings, can cause. So far, such support rollers must therefore be replaced after a short period of use.
- the inventive resilient mounting of the support rollers sheathing or protective coatings are spared and therefore, especially in heavy and / or angular cargo, only little wear exposed. The service life is extended considerably.
- the casting washing system according to the invention (for example for gearbox housing) comprises at least one washing station for the castings or parts and at least one roller conveyor according to the invention, this roller conveyor preferably being provided on the part. Casting outlet of the washing station is arranged.
- This roller conveyor has in particular a trained with spring-loaded support rollers section in which the cast pieces are blown off manually or automatically with compressed air and thereby turned.
- Fig. 1 shows schematically a roller conveyor in a side view.
- FIG. 2 shows a section through the roller conveyor according to the sectional profile indicated in FIG. 1.
- FIG. 3 shows a further section according to the sectional profile indicated in FIG. 2.
- Fig. 1 shows a trained with feet roller conveyor 100 for piece goods with rotatably mounted cylindrical support rollers or rollers 110, which form a horizontal conveying plane for the piece goods, and with two parallel side supports or side frames 120, where the rotatable support rollers 110 stored or are suspended (in Fig. 1, only one of the side support 120 is visible).
- the support rollers 110 are arranged parallel to each other. These are passive carrying rollers without drive. In principle, the support rollers 110 or at least some of the support rollers 110 may also be equipped or connected to a drive.
- the roller conveyor 100 is used, for example, for the conveyance of castings in a casting washing plant.
- the roller conveyor 100 has a portion A, in which the support rollers 110 are resiliently mounted and thereby in the vertical direction (V) can wegfedern down.
- all support rollers 110 of the roller conveyor 100 can be resiliently mounted or suspended.

- Fig. 1 shows the roller conveyor 00 only in a schematic side view.
- the roller conveyor 100 has a fundamentally identical construction on the other support carriers 123.
- the side frame 120 is constructed of profile carriers, which, for example, purchased as semi-finished, cut to length and joined in a suitable manner.
- profile carriers which, for example, purchased as semi-finished, cut to length and joined in a suitable manner.
- it is aluminum profiles.
- the support carrier 123 which is arranged with vertical alignment between lower profiled carrier 122 and upper profiled carrier 121, has a longitudinal groove 124 facing the carrying roller 11, in which a bearing element 130 is attached in an undercut manner and guided longitudinally or vertically displaceably.
- Plastic bearing member 130 is for this purpose formed with a guide portion 131 which, in particular with respect to its guide width (see Fig. 3), has a relatively large guide length.
- the bearing element 30 further has a bearing bore or bushing 135 into which a bearing journal 115 of a support roller 110 engages.
