Definitions

• a generic feeder is shown in EP 2 110 341 A1. Similar feeders are also known from DE 299 19 242 IM, DE 299 02 419 U1, DE 298 11 212 U1, DE 298 12 115 U1, DE 297 15 467 U1, DE 295 17 342 U1 or DE 200 20 945 U1 known.
• Pavers are used to apply on a course, a path or a road a pavement of Einbaumischgut, for example, concrete, bituminous Einbaumischgut or asphalt.
• a paver usually has a Gutbunker to store a certain amount of Einbaumischgut.
• a feeder in working direction is placed in front of the road paver.
• This feeder comprises a further goods bunker as well as a conveying device for transporting built-in material from the feeder bin into the hopper of the road paver.
• the conveyor may be provided as further working units, for example, scrapers, vibrators or a heater to improve the delivery process and to prevent the premature cooling and solidification of the usually hot Einbaumischgutguts.
• the unit is always running with pre-set parameters, for example preset at the factory.
• the working units comprise one or more delivery units, a scraper, a cleaning brush, a spray, a vibrator and / or a heater. Conveying belts, screw conveyors or other linear be provided. All these working units support the conveying capacity of the feeder.
• the ease of use of the feeder can be further increased if not only individual operating parameters are adjustable, but if directly the ratio of individual operating parameters of one or different working units to each other is adjustable.
• the throughput of a sprayer could be changed in proportion to the feed rate of the feeder in order to spray more or fewer additives per unit of the delivered built-in batches.
• a group of operating parameters of one or more working units is stored as a common operating program in the memory and retrievable.
• programs for a low, a medium and a high or maximum feed rate of the feeder can be stored by storing and linking the group of operational parameters that are appropriate for this purpose.
• a display field is provided on the operating area.
• information about the activity and operating parameters of the individual work aggregates could be displayed to the operator.
• a menu guide could be provided, via which the operator can retrieve the corresponding information.
• the display could also send warnings to the operator.
• an override switch is provided. When or as long as this override switch is operated, the feed rate of the feeder is set to a maximum value that can be set in advance. In particular, the delivery rate can be set to 100% of the possible delivery rate. An appropriate programming of the control ensures that all units involved in the delivery are involved in this short-term increase in delivery.
• control element is provided on the control panel, for example a rotary or sliding control, by means of which the delivery capacity of the feeder can be changed proportionally.
• the delivery rate could be changed by this factor by a certain factor.
• the control of the feeder ensures that all units involved in the delivery automatically contribute to the desired change in the delivery rate.
• FIG. 1 is a side view of a feeder according to the invention.
• Figure 2 is a view of the control panel of the feeder.
• FIG 1 shows a feeder B for supplying, for example, road pavers with tacky and / or prone to solidifying conveyed material, in particular hot bituminous mixed or built-in, concrete property or gravel, sand or the like.
• the feeder B is self-propelled, has a chassis 1 on a substructure 2 and a front bunker 3 in the direction of installation, which can be filled from the front or top or side.
• a conveyor belt M In the substructure 2 extends from the Gutbunker 3 a conveyor belt M to the rear or back and up, the conveyor belt M is oriented substantially in the longitudinal direction of the feeder B and optionally raised or lowered or can be pivoted laterally.
• Gutbunker 3 cross conveyor Q can be arranged, which bring close to the lower deflection wheels 7 conveyed onto the conveyor belt M.
• the transverse conveyors Q may be screw conveyors engaged with trays with drive shafts 8 which are supported in bearings 9.
• the cross conveyors Q is another working aggregate.
• heaters 10, scrapers, a cleaning brush, a spray unit and / or a vibrator may be provided in the goods bunker 3 or along the conveyor belt M (not shown).
• an operating area 12 On a control station 11 of the feeder B is an operating area 12, for example, as the surface of a control panel.
• This operating area 12 is shown in FIG.
• the operating area 12 comprises a display field 13, for example an LCD display.
• the operator can move through a menu on the display 13 to retrieve certain information there, as well as operating conditions and operating parameters of various work units M, Q, 5, 10, to select and set.
• a main conveyor switch 15 On the operating area further controls are provided, in particular a main conveyor switch 15, an override button 16 and a rotary knob 17th
• the operator Before switching on the conveying process, the operator first activates the operating area 12.
• the operator sets the operating state of the individual working units M, Q, 5, 10 via the display keys 14. For each unit, it can choose between the three settings OFF / ON / AUTOMATIC.
• the OFF operating state the relevant working unit remains out of operation.
• the working unit In the operating state ON, the working unit always runs with predefined parameters which, for example, can be predetermined at the factory.
• the AUTOMATIC operating state the unit runs with previously set parameters when or as long as the delivery main switch 15 is actuated.
• a store is provided on the feeder B (not shown). The operating parameters are stored in this memory.
• the override button 16 gives the operator the opportunity to temporarily override the conveying process or to go to a maximum capacity of the feeder B to bridge any material bottlenecks.
• the maximum delivery rate achieved in this case does not have to correspond to the technically achievable maximum delivery rate of the feeder B. Rather, a percentage of the technically feasible delivery rate can be set and when the override button is pressed
• the invention can be modified in many ways.
• further work units may be present be, for example, a setting for the inclination of the conveyor belt M.
• the chassis or the drive of the entire feeder B can be controlled as a working aggregate.
