Description

[Technical Field]

[0001] The present invention relates to a road paving machine comprising a material hopper for receiving production material according to claim 1, a combination of a feeder vehicle and a road paving machine according to claim 13, and a method for feeding into the material hopper of a road paving machine according to claim 14. [Background Art]

[0002] Road paving machines are well known from the prior art. A road paving machine comprises a material hopper, into which production material for producing a road surface can be fed using a feeder vehicle such as, for example, a truck. To this end, the material hopper is filled with production material, which is conveyed from the material hopper to a screed in the road paving machine and supplied there as a road surface.

[0003] It is known that the production material needs to have a certain minimum temperature when being spread, otherwise it becomes difficult to produce the road surface. In order to avoid or at least reduce cooling of the production material in the material hopper, it is also known to configure the boundary surface of the material hopper to be foldable or generally movable, which allows the production material to be fed into the material hopper in an open position, after which the material hopper or the side walls thereof can be moved to a closed position, in which heat conduction from the production material to the ambient air is at least partially reduced.

[0004] However, conventionally known foldable material hoppers have the disadvantage that a loading truck may collide with the side walls of the material hopper. This is particularly the case when the truck comprises a trailer coupling, which is usually located lower than the loading area of the truck on which the production material is loaded. [Summary of the Invention] [Problem to be Solved by the Invention]

[0005] Based on conventional technology, the technical challenge to be addressed is to provide a road paving machine that enables reliable feeding of materials while reducing the risk of damage to the material hopper. [Means for solving the problem]

[0006] This problem is solved by the road paving machine described in claim 1, the combination of a feeder vehicle and a road paving machine described in claim 13, and the method of feeding material into the material hopper of the road paving machine described in claim 14. Further advantageous embodiments of the present invention are included in the dependent claims.

[0007] The road paving machine according to the present invention includes a material hopper for receiving material to be made, the material hopper includes an outer boundary that at least partially isolates the interior of the material hopper from the surroundings, the material hopper can be fed with material to be made, for example, by a feeder vehicle, and the outer boundary includes a multi-part flap for closing the material hopper, the first movable part of the multi-part flap in the open position being lower than the second movable part of the multi-part flap in the open position, and the movement of the first and second movable parts from the open position to the closed position where the material hopper is closed is at least partially operationally coupled.

[0008] Considering the example of a cubic material hopper, the multi-part flap may, for example, be part of the side of the cube. In the open position, the multi-part flap extends outward from the volume of the cube, and in the closed position, it forms part of the side. Thus, it can be understood that the multi-part flap defines a larger area of ​​internal space in the closed position than in the open position. In general, the internal space can be understood as the volume defined by the material hopper when the multi-part flap is in the closed position, and, where applicable, the volume defined by the material hopper when other movable parts of the outer boundary are in the closed position.

[0009] In the present invention, the fact that the first movable part in the open position is lower than the second movable part of the multi-part flap in the open position should be understood to mean that at least a portion of the first movable part, preferably a portion of the first movable part facing away from the internal space of the material hopper, has a lower upper boundary than the second movable part. In this case, the first movable part in the open position does not need to be completely lower than the second movable part; it may be at least partially lower.

[0010] By positioning the first movable part lower than the second movable part, reliable feeding into the material hopper is ensured with a reduced risk of damage, while the material hopper is reliably closed with reduced heat loss of the manufactured material.

[0011] It is conceivable that the first movable part has a first upper end of the first outer interface, and the second movable part has a second upper end of the second outer interface, and in the open position, the first upper end is lower than the second upper end. The first or second upper end may be straight or curved. In the case of a curved upper end, preferably the second upper end may be higher than the first upper end at all points, or at best at the same height. This prevents the fabricated material from falling from the vicinity of the second upper end.

[0012] In one embodiment, a first movable part is mounted to be rotatable about a first pivot axis for movement from an open position to a closed position, and a second movable part is mounted to be rotatable about a second pivot axis for movement from an open position to a closed position. By rotating the first and second movable parts from the open position to the closed position, it is possible to prevent the material from falling, in particular when the rotation causes the first and second movable parts to move upward, causing the material to slide into the internal space of the material hopper.

[0013] The first and second axes of rotation may be parallel, or they may be at an angle to each other, or they may be the same. By configuring the first and second axes of rotation to be parallel, the second movable part can be moved more reliably together with the first movable part. A configuration in which the first and second axes of rotation are at an angle to each other may be preferable in order to prevent the fabricated material from falling.

[0014] The first movable part may include a follower, which engages with a second movable part so that the second movable part is driven by the first movable part. In this way, the second movable part can move mechanically in conjunction with the movement of the first movable part, thereby potentially reducing the risk of failure.

[0015] The second movable part may include two flap elements positioned on either side of the first movable part. This minimizes the risk of damage during insertion and prevents accidental dropping of fabricated material into the outer area of ​​the first movable part, as the lower-positioned first movable part is surrounded by the higher-positioned flap elements.

[0016] The movement of the first movable part and / or the second movable part may be performed by a drive element. The drive element may include a fluid pressure drive element, a mechanical drive element, or an electric drive element. In this embodiment, the motion coupling between the first movable part and the second movable part may be achieved with the assistance of a control device, for example, in the form of a computer with associated storage, particularly by a suitable controller. This makes it possible to move the first movable part and the second movable part from an open position to a closed position in a more flexible manner, and allows for flexible adaptation to, for example, various types of feeder cars and their corresponding requirements.

[0017] The maximum distance from the ground to the point of the first movable part in the open position may be less than 50 cm, less than 45 cm, less than 40 cm, or less than 30 cm. The distance from the ground is measured here with the road paving machine normally positioned on a flat surface. The small distance between the highest point and the ground ensures that feeder car components, such as trailer couplings, extend above the first movable part and enter the internal space of the material hopper. This prevents collisions between the feeder car or its components and the material hopper, thus avoiding damage.

[0018] In one embodiment, a first movable part and a second movable part are operationally linked to each other such that the movement of the first movable part along a first distance from an open position to a closed position is performed without the movement of the second movable part simultaneously, while the movement of the first movable part over a second distance after moving the first distance from the open position to the closed position is performed with the movement of the second movable part simultaneously.

[0019] The first distance may be selected, for example, so that after moving this distance, the first movable part is at the same height as the second movable part. Then, when the two are moved together in the direction of the closed position, the fabricated material is prevented from falling. In this embodiment as well as in all other embodiments, in particular, the first movable part and the second movable part may be positioned relative to each other such that there is no gap between them through which the fabricated material can pass at any position between the open position and the closed position, including the open position and the closed position.

[0020] The first movable part may include a flexible or movable element that extends at least partially vertically in the open position of the first movable part and is capable of being tilted by force toward the internal space of the material hopper. The flexible element may be, for example, a rubber strip. The movable element may be, for example, a flap, a rotatable metal plate, or a plate made of another material, preferably the same material as the material of the material hopper. The flexible or movable element can, on the one hand, prevent the material being produced from falling, and on the other hand, further reduce the risk of damage.

[0021] The first and / or second movable parts may include a surface that inclins toward the internal space when in the open position. This surface can be understood, for example, as the base of each part. By configuring this surface to inclin toward the internal space when in the open position (i.e., to slope downward toward the internal space), it is ensured that any material laid toward this surface falls into the internal space of the material hopper, or at least falls into the internal space of the material hopper as the first or second movable part moves.

[0022] According to the present invention, a combination of a feeder vehicle and a road paving machine according to one of the above embodiments is also provided, the feeder vehicle being able to supply material to a material hopper, and the multi-part flap being able to be positioned open while supplying material and closed after supplying material. Such a combination of feeder vehicle and road paving machine ensures reliable feeding of material into the material hopper while reducing the risk of damage to the feeder vehicle and the material hopper.

[0023] Furthermore, a method for feeding material into a material hopper of a road paving machine according to one of the above embodiments is provided, which includes positioning a multi-part flap in the open position, then positioning a feeder vehicle to supply the material to the material hopper, moving the feeder vehicle away from the material hopper at least partially, and then moving the multi-part flap in the closed position. This method ensures reliable feeding of material into the material hopper while reducing the risk of damage to the feeder vehicle and the road paving machine, particularly the material hopper. [Brief explanation of the drawing]

[0024] [Figure 1] This figure shows a road paving machine according to one embodiment. [Figure 2] This is a schematic diagram of the material hopper. [Figure 3]It is a diagram showing an embodiment of a movement sequence when moving a multi-component flap from an open position to a closed position. [Figure 4] It is a diagram showing an embodiment of a movement sequence when moving a multi-component flap from an open position to a closed position. [Figure 5] It is a diagram showing an embodiment of a movement sequence when moving a multi-component flap from an open position to a closed position. DESCRIPTION OF EMBODIMENTS

[0025] FIG. 1 is a schematic diagram showing a combination of a road paver 100 and a feeder truck 180. In the embodiment shown herein, the feeder truck 180 is configured as a truck having a receiving area 182 that accommodates production material 181 to be supplied to the road paver 100. Other embodiments are also conceivable.

[0026] The road paver 100 includes a material hopper 101 into which production material 181 can be loaded from a feeder truck. The production material is accommodated in this hopper and supplied to a screed 102 at the other end of the road paver 100, for example, for spreading onto a road under construction. The exact configuration of the road paver 100 is not limited and may be of any known type.

[0027] The material hopper 101 is substantially configured to include an outer boundary 111 that at least partially isolates the internal space 110 of the material hopper from the surroundings. The internal space of the material hopper should be understood as the volume of the material hopper surrounded by the outer boundary 111 in a closed state, as described below. The outer boundary may, for example, be formed from or include a plurality of movable and / or non-movable (fixed) metal plates. In this case, the material hopper need not be configured such that the internal space 110 is completely surrounded by the outer boundary 111, and may include an opening at the top, for example.

[0028] According to the present invention, the outer boundary may include a multi-part flap 112, which is shown schematically here and will be described in more detail in further embodiments, and can be used as part of a boundary that at least partially closes the material hopper. The multi-part flap 112 is configured to be movable, and in the open position shown herein, preferably at least a portion of the multi-part flap (a first movable part of the multi-part flap, as described later) is positioned at a height h from the ground or is configured to end at a height h from the ground, where the height h is lower than the height at which a second part of the multi-part flap is positioned in the open position. This allows a component 183 of the feeder car 180 to enter the material hopper without damaging the material hopper, particularly the multi-part flap. The component 183 of the feeder car 180 may be, for example, a trailer coupler, which extends to the rear of the feeder car 180 and is typically positioned below the receiving area 182 for the fabrication material 181.

[0029] The multi-component flap 112 according to the present invention allows the feeder car 180 to approach the road paving machine 100 as closely as possible without damaging the material hopper 101, thereby enabling the material to be fed into the material hopper with the least possible loss without damaging the material hopper or the feeder car.

[0030] Figure 2 is a schematic diagram of the material hopper 201. The material hopper includes several components that are at least partially movable, forming an outer boundary 220. For example, sides 236 and 237 are provided, which can move along the directions of the double arrows shown to open and close the material hopper. These sides 236 and 237 may be configured to move up and down and / or rotate (pivot) in the direction of the internal space of the material hopper, for example, to lift the material towards the center of the material hopper 201 and ensure that the material is supplied to the discharge area 295 where an auger or scraper belt may be positioned.

[0031] The outer boundary 220 may also include the blade surfaces 234 and 235 shown herein in part 210 of the material hopper facing a feeder car, which is not shown herein. This configuration is not mandatory and should be understood as merely an example. These blade surfaces may be movable and, in particular, may be configured to be foldable and / or rotatable so that they can be moved from an open position to a closed position that defines the internal space of the material hopper.

[0032] According to the present invention, the material hopper 201 further includes a multi-part flap 230. The multi-part flap is formed here by a first movable part 231 and at least one second movable part 233. The first movable part may be configured as a central part, such as a central plate, and the second movable part may include at least two flap elements 232 and flap elements 233 located on either side of the first movable part. Hereinafter, the second movable part will be referred to by two reference numerals, but it will be understood that the second movable part may be configured as a single unit, for example, the second movable part may include only one flap element 232 or flap element 233.

[0033] According to the present invention, the first movable part 231 of the multi-part flap 230 is positioned lower in the open position shown herein than the second movable parts 232 and 233 of the multi-part flap in the open position, i.e., the position in which the multi-part flap is not closing the material hopper.

[0034] Furthermore, the present invention provides that the multi-part flap 230 is configured to be movable such that the movement of the first movable part and the second movable part from the open position to the closed position can be performed in an operationally coupled manner. Operational coupling means that the first movable part 231 and the second movable parts 232, 233 move at least partially together, i.e., simultaneously, throughout the entire movement from the open position to the closed position or vice versa. This may also include the movement of the first movable part causing the movement of the second movable part. Although at least partially simultaneous movement is provided, this does not necessarily mean that the first movable part and the second movable part move by the same amount. Therefore, the first movable part and the second movable part may move different distances, for example, despite the coupling of the movements.

[0035] In the embodiment shown in Figure 2, the coupling of the movement of the first and second movable parts is achieved by the first movable part 231 having followers 261, 262, the followers 261, 262 engaging with the second movable part 232 or 233, and being able to drive the second movable part while the first movable part is moving. The followers may be configured, for example, as metal fingers extending from the first movable part toward the second movable part. Other configurations are also possible. Although not shown herein, optionally the second movable part may include a guide for the follower 261 or 262, such that the follower moves along the guide. This ensures a secure coupling of movement.

[0036] This type of motion linkage between the first and second movable parts is a purely mechanical linkage of movement, and it can be assumed that the first movable part 231 is actively driven between an open position and a closed position, for example via a drive element 270. Followers 261 and 262 then move the second movable part in motion linkage with the movement of the first movable part.

[0037] However, alternatively, instead of a single drive element 270 for the first movable part 231, a drive element 270 for the first movable part 231 and drive elements (not shown separately here) for the second movable parts 232 and 233 may be provided. In this case, a control unit 280, for example in the form of a computer or a processor with associated memory, may be configured to enable control of each drive element so that the first movable part and the second movable parts can move in a state where they are at least partially operationally coupled. It is particularly advantageous that the movement and configuration of the first and second movable parts ensure that no gap is formed between the first and second movable parts in either the open or closed position, preferably any position in between. This prevents the fabricated material from falling.

[0038] The drive element 270 can be arbitrarily designed, but preferably, embodiments of the drive element are configured as, for example, a fluid pressure drive element in the form of a pneumatic cylinder, as a mechanical drive element in the form of a shaft connected to, for example, the first and second movable parts, or as an electric drive element in the form of an electric drive unit or servo motor. By using separate drive elements for the first and second movable parts and combining them with the corresponding control unit 280, flexible control of movement becomes possible, and in particular, it becomes possible to control the position of the first movable part in the open position according to the height of the trailer coupling of the feeder car. If the trailer coupling or another part of the feeder car extending into the material hopper is located at a higher position, it may be sufficient not to position the first movable part too deeply. In particular, in the case of a rotatable first movable part (see below), this can make it easier to slide the material into the internal space of the material hopper while keeping the risk of damage to the material hopper and feeder car low.

[0039] In principle, the movement of the first and second movable parts between the open and closed positions may occur around the rotation axis 260, which is shown only schematically here. In this case, the first and second movable parts tilt at least around the rotation axis 260 in order to reciprocate between the open and closed positions.

[0040] The first and second movable parts may be mounted so as to be rotatable around the same axis of rotation 260. Alternatively, the axes of rotation of the first and second movable parts may not coincide but be parallel to each other. For example, the axis of rotation of the second movable part may be offset by up to 10 cm or up to 20 cm in the direction of internal space compared to the axis of rotation 260 of the first movable part.

[0041] Alternatively, these axes of rotation may be angled relative to each other. Angle formation is particularly preferable here to avoid gap formation, for example, by partially moving the first or second movable part behind the other part.

[0042] In the embodiment shown in Figure 2, the first movable part 231 is formed from two parts. This is not essential, and other embodiments, particularly an integrated design of the first (and / or second) movable part, are possible. In the embodiment shown herein, the second movable part 231 includes a surface 241, which may extend substantially horizontally or slightly inclined. This surface can function, for example, as a receiving surface for the fabrication material.

[0043] Furthermore, the first movable part includes a flexible or movable element 242, which, in the embodiment shown here in Figure 2, extends substantially perpendicular to the surface 241 and forms the outer boundary of the first movable part 231, so that the material being processed cannot be moved from inside the material hopper 201 beyond this outer boundary. The flexible or movable element 242 may be configured, for example, as a thin metal plate that is rotatably mounted, which can be tilted toward the internal space of the material hopper but cannot move in the opposite direction, i.e., toward the outside, beyond a certain end position. This ensures, for example, that a feeder car can enter the vicinity of the first movable part together with its trailer coupling by tilting the plate 242 toward the internal space. This reduces the distance between the feeder car and the material hopper, thereby reducing the risk of material being processed falling during feeding. At the same time, damage to the material hopper due to the entry of the trailer coupling is prevented.

[0044] Furthermore, the plate 242 may be connected to a spring element (not shown) that biases the plate 242 to an upright position as shown herein. In this case, the inclination of the plate 242 toward the internal space of the material hopper is possible against the spring force and can be done, for example, by the trailer coupler described above.

[0045] After the material is removed from the material hopper (for example, after the material hopper is filled), the biasing force on plate 242 returns the plate to the initial position shown here.

[0046] Instead of a plate mounted to be movable, element 242 may be made of or include a flexible material, for example. For example, it may be a polyurethane rubber lip, or it may include at least a polyurethane outer coating. The flexible element may be manufactured to take the position of element 242 shown here when no force is applied, as shown in Figure 2 as an example. The flexible element is then deformed by the application of force by the trailer coupler or the like, and is pushed, for example, in the direction of the internal space of the material hopper, thereby allowing a part of the feeder vehicle, such as the trailer coupler, to enter this area.

[0047] Although this description is limited to the first movable part 231, a corresponding design may also be provided for the second movable part.

[0048] In the embodiments shown herein, the surface 241 of the first movable part in the open position is lower than the corresponding surfaces of the second movable parts 232 and 233. While this may be sufficient to prevent damage to the material hopper, alternatively or additionally, if the first movable part has a non-movable (fixed) outer interface in the form of element 242, this element may include an upper end 291 that is lower or deeper than the corresponding upper end 292 of the second movable part. This can prevent the material being produced from falling while simultaneously reducing damage to the material hopper.

[0049] Figures 3 to 5 schematically illustrate a series of operations for closing a material hopper, particularly for moving a multi-part flap from an open position to a closed position. Figure 3 shows the material hopper 301 in the open position. In this context, this means that a multi-part flap, including a first movable part 331 and second movable parts 332, 333, is positioned in its open position. As already described, the present invention provides that in this open position, the first movable part is positioned lower than the second movable part of the multi-part flap, thereby preventing damage from, for example, parts located below the feeder car.

[0050] When closing the material hopper, the multi-part flap needs to be moved from its open position to its closed position. Figure 4 shows the intermediate stage. In Figure 4, the first movable part 431 is moved from its open position towards the closed position. As already described, this can be done, for example, by rotating the first movable part around a pivot axis. As can be seen from the figure, the position of the second movable part does not change as a result of the movement of the first movable part. Thus, the path or distance that the first movable part moves from Figure 3 to Figure 4, starting from the open position, is achieved in this embodiment without the second movable part moving. The first distance to be moved can be selected, for example, so that the first and second movable parts are at the same height at the end of this distance. At this position, the follower (see Figure 1) can drive the second movable parts 432, 433 so that they follow the movement of the first movable part 431 towards the closed position.

[0051] If no follower is provided, and instead drive elements are considered for the first and second movable parts respectively, the movement of the first and second movable parts is controlled by the operation of the drive elements such that the second movable part moves only after the first movable part has moved a first distance. Then, for a second distance, the first and second movable parts move in conjunction (linked).

[0052] The second distance may include, but does not necessarily include, the total distance traveled by the first and / or second movable parts until they reach the closed position. For example, the second movable part may reach the closed position before the first movable part, in which case the first movable part will continue to move even after the movement of the second movable part has finished. The first movable part 431 may reach its closed position before the second movable parts 432 and 433 reach their closed positions.

[0053] In Figure 4, not only are the second movable parts 432 and 433 not moving, but the wing surfaces 434 and 435, which may be optionally provided as described in Figure 2, also remain in their open positions. As mentioned above, these are merely examples and are not necessarily required. Similarly, these parts do not need to be operationally coupled to the multi-part flap. Therefore, their movement may occur independently of the movement of the parts of the multi-part flap.

[0054] Finally, Figure 5 shows the closed position of the storage bin. As can be seen from the figure, the first movable part 531 and the second movable parts 532, 533 have been moved further in the direction of the internal space of the material hopper around the axis of rotation, starting from Figure 1. The sides 534 and 535 have also been moved to their closed positions, and elements 536 and 537, which have already been described as elements 236 and 237 in relation to Figure 2, have been folded toward the internal space of the material hopper so that the internal space of the material hopper is enclosed as completely as possible so that no material falls out.
