TRANSPORT-SYSTEM

Description

[0001] The invention relates to a transport element system for controlling systems in a wide variety of technical areas, including heavy-duty areas, for example for freight and passenger lifts, material transport in high-bay warehouses and associated transport means, such as conveyor belts, forklifts, cable cars, overhead conveyors, etc.

[0002] US 4,991,516 A discloses a transport system for workpieces, comprising longitudinally extending rail segments that continue along an original path at a branch or change in the direction of the curve only by reversing the track, and further longitudinally extending rail segments that branch off from the first segments at a branch, as well as a workpiece transport carriage mounted on the rails and displaceable along the rail. The object of the invention is to provide an improved transport system in which the rail system can remain passive, so that all elements and controls for diverting the carriages onto a branch or into a differently oriented curve can be controlled by reversible movement back on the main track section and then further into the branching section.The disadvantage of this solution is that the rail system is only made up of two straight and curved elements on one plane (see Fig. 7). This means that curves can only be made in one direction. In order to travel in other directions, the carriage must be steered by reversing along a straight line and then in another direction. Reversing is necessary for junctions with two rail elements (see Fig. 4b). The transport system cannot move vertically (z) in three dimensions. Due to the rigid design of the rail elements, two transport rails are required for junctions. The rail system can only move in one plane in two directions: forwards (x) and backwards (y), in a straight line and in a curved manner. This means that the transport system can only be used for the transport of goods (not for the transport of people).

[0003] WO 2022 / 042870 A1 discloses a linear inverted tooth chain drive with a flexible inverted tooth chain toothed on both sides. The tooth flanks of the inverted tooth chain mesh with receiving openings on the output side of a conveyor element, and the tooth flanks of the inverted tooth chain wheels with involute toothing on the drive side. The inverted tooth chain is equipped with involute tooth flanks on the output side and combined with the tooth flanks of the involute toothing on the drive side. The tooth flanks of the involute toothing roll in receiving openings of a conveyor element that are symmetrical even in curved areas and are directed towards the inverted tooth chain on the output side.The conveyor element is a largely rigid belt with, on the one hand, symmetrical receiving openings open inwards or outwards and, on the other hand, spaced slots running transversely to the running direction on the opposite outer surface, which are formed in an outer surface of a polygonal profile part and form the conveyor element. The disadvantage of this solution is that the conveyor element with its receiving openings and slots can only be arranged separately in a horizontal or vertical direction on an outer surface, and the linear chain drive can only be moved thereon. The switches mentioned in the publication, which are intended to enable the linear chain drive to change from a horizontal to a vertical movement and vice versa, are not recognizable in a technically, fundamentally recognizable design for a person skilled in the art, either in the text or in the drawings.

[0004] One of the disadvantages of conventional linear drive technologies is that the gears on the output side are often guided in racks, with fine toothing allowing only one tooth, or a maximum of 1.5 or 2 teeth, to mesh at a time. Roller chains have excessive play between the chain links in the teeth, causing the chains to wear and expand at the joints, which in turn leads to inaccuracies in adjustments. For example, ropes in cable cars stretch and can break. Regular safety inspections are required, during which chains or ropes, etc., must be replaced, resulting in time-consuming, material-intensive, and costly processes.

[0005] The particular disadvantage of this state of the art is that the drive devices guided on an outer surface of a transport element, such as linear tooth chain drives, concentric gear motors, etc., must be arranged in separate housings and stored and transported outside the transport element, which requires additional work space and external transport.

[0006] It was therefore an object of the invention to find a transport element system in which all necessary drive devices, power supplies and coupling elements can be moved continuously in a housing in simple or three-dimensional directions, as required depending on the application, and enable spatial, cylindrical or square or such combined movement, have a high degree of efficiency and a high degree of structural simplicity, which do not require any additional stationary storage spaces for drives, etc. and ensure considerable savings in material and time expenditure.

[0007] The object is achieved with the features of claim 1, in that, on the basis of the underlying prior art, a transport element system is formed, comprising a transport element consisting of a polygonal profile part, on one longitudinal surface of which a largely rigid belt is arranged, and a carriage, which engage with each other in such a way that the carriage can be guided and moved within the transport element and can be moved outside the transport element with a respectively adapted connecting element for connecting and controlling applications, and the transport element is composed of hollow profile parts which have a linear shape and a curved shape, each of which is equipped in a profile surface with a guide opening running continuously along the running direction, in which, on an inner surface opposite the guide opening, a transport belt and a conductor rail are arranged parallel to each other,which run continuously according to the shape of the profile parts, that in the transport element the conveyor belt has symmetrical receiving openings in which a linear toothed chain drive with a double-sided toothed and flexible toothed chain, which is combined on the output side with tooth flanks of an involute toothing and on the drive side with tooth flanks of a pointed toothing and whose output-side tooth flanks engage and roll in the symmetrical receiving openings and the toothed chain drive is to be moved in the transport element, and the conveyor belt is mounted in a non-slip support and the transport element, in addition to the hollow profile parts in linear and curved form, also has counter-rotating torsional shapes, that the carriage consists of a cover surface with legs that are vertically angled on both sides, the outer surface of which has a connecting element adapted for coupling with the respective application and to which a one-sided vertical,centrally arranged and T-shaped partition wall, on which, horizontal to the direction of travel, brackets with rollers arranged on both sides, opposite each other in a vertical and horizontal direction, are held and guided, and that after insertion of the carriage into the transport element, the cover surface with the legs and the adapted connecting element of the carriage protrudes above the transport element, the partition wall protrudes into the guide opening of the transport elements arranged vertically to the direction of travel and is movably guided by the rollers at the end on the inner surface between the support with the conveyor belt and the conductor rail.

[0008] Particularly noteworthy is the considerable variability of the transport element system according to the invention, which is provided by the interlocking of a transport element with a carriage, the structural design of which allows the spatially direct contact of a linear toothed chain drive with a compact, concentric gear motor, the current-carrying elements and their contact securing with application systems of any kind and which can be moved and transported in all directions within the transport element with all the devices arranged therein, which can be moved in three-dimensional direction depending on the guide direction of the conveyor belt.Since the connecting element is adapted to the respective application and variably arranged on the outer surface of the ceiling section of the carriage protruding from the transport element, no additional stationary storage spaces or housings for drives and their interaction with the respective application systems are required. This also achieves greater efficiency and ensures significantly lower material and time expenditure.

[0009] The construction according to claim 2 is also advantageous in that the unequipped carriage on the partition wall and its holders are equipped with a linear toothed chain drive, a compact concentric gear motor, a power supply and a servo controller, cooperating with each other on both sides, and are three-dimensionally movable within the transport element in the horizontal direction, in the vertical direction or in a direction facing away from the horizontal or vertical plane in the respective running direction.

[0010] Another advantage of the structural design according to claim 3 is that the loaded carriage is equipped with two additional horizontal rollers on both sides at the front and rear ends, between the inner surface of the legs and the two opposite outer surfaces of the transport element, which ensure smooth movement. The movement of the loaded carriage is guided and maintained by the rollers arranged horizontally to the direction of travel on the brackets of the partition wall, opposite each other in the vertical and horizontal direction, on both sides. In combination with the rollers arranged on the partition wall of the carriage, which ensure smooth movement inside the transport element, the rollers between the outer wall of the transport element and the inner surfaces of the legs on the carriage ensure a stable running line for the carriage outside the transport element.

[0011] Also worth highlighting is the structural design according to claim 4, characterized in that the linear toothed chain drive arranged on the partition wall of the carriage with its toothed chain toothed on both sides engages in the receiving openings of the conveyor belt, which is mounted in the support of the conveyor belt, that magnets are to be received between the conveyor belt and the support and that they are to be driven and moved by the toothed chain drive and the compact concentric gear motor also arranged in the carriage.

[0012] Particularly noteworthy is the structural design of the transport element modified according to the invention, according to claim 5, in which the transport element is to be used via the guide opening with the conveyor belt arranged in it on the opposite inner surface and the power rail to determine the forward and backward movement and its direction and to control and maintain the contacting of all devices to be moved for power supply and to connect them to one another and to the respective application via the respective connecting element.

[0013] The interaction of the drive components within a housing consisting of a transport element and a carriage eliminates the need for an additional housing for the drive components, as well as their combination and movement, which was previously required outside the transport element and required considerable additional space. Furthermore, with the transport system according to the invention, the drive elements are always available on site, depending on the application, and can be carried along with the carriage in the transport element when changing direction.

[0014] Also noteworthy is the structural design of the transport element according to the invention, as defined in claims 6 and 7, in which several single-rail transport elements are interconnected in a predetermined sequence, consisting of profiled parts of linear and curved shapes and counter-rotating torsional shapes. One or more drives are movably mounted in the transport elements, which can also be moved in a three-dimensional direction via arranged switches. The switches are arranged through, above, or below the linear area of ​​the respective transport element and, as required, additionally control individual drives in an arcuate or Y-shaped direction via the associated carriages.

[0015] Depending on the application, the linear inverted tooth chain drive with multiple synchronized drives can be easily moved vertically and horizontally without any transitions. The necessary transport elements can be created by assembling linear, curved, or torsionally shaped hollow profile sections as required. With intermittent tooth engagement, the inverted tooth chain can move freely in the x, y, and z directions. With a torsionally shaped, single-rail hollow profile section, the existing play between the chain plates can easily compensate for the skew of the chain. By rotating the torsionally shaped hollow profile section by 90°, the inverted tooth chain can be brought into the positive convex position when traveling around curves, which tensions the inverted tooth chain.

[0016] Finally, a constructive form according to claim 8 is to be emphasized, in that several transport element systems, the transport elements of which have a uniform line guidance by arranging a respective identical sequence of specific single-rail profile shapes as well as further, individually adapted multi-rail profile shapes with a guide opening, and from each of which a carriage with a connecting element protrudes, which are arranged at a distance to be defined from one another, which in the case of the multi-rail profiles form a helix and overall a free space, wherein the carriage is to be moved inside the respective transport element via the linear toothed chain drive into the receiving openings of the conveyor belt on the respective inner surface in the transport elements and via the concentric gear motor and a spatial, square or cylindrical, to be closed on both sides,Transport box with a rotating top section and bottom section connected by connecting elements to the carriage in a continuously vertical position, held by the carriage and spirally rotatable within the free space and simultaneously vertically movable.

[0018] An embodiment, according to Fig.1, shows a front view of a transport element system 0, with, for example, a square transport element 2 and a carriage 3 inserted into the transport element 2. The transport element 2 is equipped with a continuously open guide opening 2.7, the edges of which are formed, for example, on both sides inwards in a straight line in the vertical direction and from there at right angles to the partition 3.4 of the transport element 2. In the interior of the transport element 2, on an inner surface 2.8 opposite the guide opening 2.7, a conveyor belt 2.9 is arranged. The conveyor belt has receiving openings 2.1 and is non-slip fastened, for example, on magnets 2.12 and an underlying support 2.11. Parallel in a plane next to the conveyor belt 2.9 is a current guide rail 2.10, also in the direction of the guide opening 2.7 and the conveyor belt 2.9, which together form the unloaded transport element 2. The carriage 3 has a T-shaped basic form. A cover surface 3.1 is equipped at both ends with preferably integrally formed, vertically extending legs 3.2 and 3.3, to the outer surface of which a connecting element 4 adapted to the respective application is preferably firmly welded to the cover part 3.1.

[0019] In the same vertical direction, a central T-shaped partition 3.4 is arranged, which is also preferably welded to the ceiling part 3.1. Brackets 3.4.1, 3.4.2, 3.4.3, 3.4.4, 3.4.5 and 3.4.6 are attached to the partition 3.4 horizontally to the running direction, for example, detachably screwed, which are directed away from the partition 3.4 on both sides at the same width. The length of the partition 3.4 corresponds approximately to the inner length of the respective transport element 2. Rollers 3.5 arranged opposite one another in the vertical and horizontal directions are held and guided on both sides of the brackets 3.4.1, 3.4.2, 3.4.2, 3.4.3, 3.4.4, 3.4.5 and 3.4.6. The carriage 3 is now, according to Fig. 2 and Fig.3with a linear toothed chain drive 1, a concentric gear motor 5, a servo controller 5.1 and a power supply 5.2 as well as with the rollers 3.5, preferably mechanically screwed. When the loaded carriage 3 is inserted into the transport element 2, the cover part 3.1 comes to rest on the outside of the upper part of the transport element 2 in the direction of movement. The angled, molded legs 3.1 and 3.3 run vertically to the right and left from the cover part 3.1 to the transport element 2. The loaded partition 3.4 is inserted from the front in the direction of movement into the guide opening 2.7 of the transport element 2, whereby the linear toothed chain drive 1, the connected concentric gear motor 5, the servo controller 5.1 and the power supply 5.2 and the rollers 3.5 to the right and left of the partition 3.4 are inserted into the cavity of the transport element 2. It is important during insertion that, according to Fig. 3, the teeth of the double-sided toothed chain 1.1 on the drive side engage with the receiving openings 2.1 of the conveyor belt 2.9 of the transport element 2, with the involute toothing engaging with the gears of the concentric gear motor 5, and from this the linear tooth chain drive 1 is driven on the drive side, and a selected application is driven on the output side. All transport movements and forward movements for the carriages 3 with the devices to be moved and a transport box 7 are controlled by the power supply and connection elements, not shown in detail in the drawings. The seal 3.6 must then be inserted into the groove of the guide opening 2.7 to prevent moisture and dust from penetrating the interior of the transport element systems 0.

[0020] In a second embodiment, according to Fig. 4, a single-rail linear three-dimensional application of the inventive transport element system 0 is shown, for example, with three drives, whose carriages 3 protrude from the continuous guide openings 2.7. In this example, a system is composed of differently designed transport elements 2 with the aid of exemplary single-rail base profiles 2.3, 2.4, 2.5 and 2.6, which are shown in the Fig. 4.1, 4.2, 4.3, 4.4are shown. These are assembled in the following sequence: curved profiles 2.4, torsion-shaped with left-hand twist 2.5, torsion-shaped with right-hand twist 2.6, again curved 2.4 and straight 2.3. In the three-dimensional single-rail application, for example, a straight hollow profile 2.3 is guided vertically along a y-axis, followed by an arc-shaped profile 2.4 in a horizontal direction along an x-axis, followed by two torsion-shaped profiles 2.6 and 2.5, then another arc-shaped profile 2.4 in a direction opposite to the horizontal shape along a z-axis with a straight profile section 2.3. The torsion-shaped profile sections are available with a left-hand twist or a right-hand twist by rotating them through 90°, as required. In all of the transport element parts 2 arranged in a row, guide openings 2.7 are arranged continuously in an outer surface of each transport element 2.Inside the transport elements 2, on the inner surface 2.8, which is opposite the guide opening 2.7, there is a conveyor belt 2.9 with incorporated receiving openings 2.1, which is arranged, for example, on magnets 2.12 and then on a support 2.11 in a non-slip manner on the inner surface 2.8 and parallel to it a busbar 2.10, which is shown in the drawings . Fig. 4 . 1 to 4.4 are marked with hidden numbers.

[0021] In a third embodiment, a straight switch 8, according to Fig. 5 This switch shape can also be curved, according to Fig.5.1be used. In the example, only single-rail straight profiles 2.3 and curved profiles 2.4 are connected to each other. For example, four complete transport element systems 0, in which preferably 8 drives are arranged, whose carriages 3 protrude from the guide openings 2.7, are assigned to each other in such a way that they form, for example, a square cavity 6, in which, according to Fig. 5 , a transport box 7 can be moved vertically in a straight line. Fig. 5.1 shows that the linear transport element systems 0 are each combined with an arcuate transport element system 0, into which the respective transport boxes 7 can be controlled in an arcuate manner by the drives. A Y-shaped switch connection is also possible in this way.

[0022] Finally, a fourth embodiment according to claim 8 in Fig.6shown. In this example, four transport element systems are preferably used, the transport elements 2 of which have a uniform line layout by arranging a respective identical sequence of specific single-rail profile shapes 2.3 and multi-rail profile shapes 2.13, 2.13.1, 2.13.2 and 2.13.3, right-hand or left-hand twist, with a guide opening 2.7, from each of which a carriage 3 with a connecting element 4 protrudes, which are arranged at a defined distance from one another. In the present exemplary embodiment, multi-rail profile parts 2.13, 2.13.1, 2.13.2 and 2.13.3, preferably right-hand twist, are arranged vertically between the single-rail profiles 2, 3, the guide openings 2.7 of which must each be machined individually depending on the application conditions, such as transport path, curve angle, etc., and which form a helix.Within the transport element systems 0, a hollow space 6 is formed over the entire length, with the carriage 3 inside the respective transport element 2 being moved via the linear chain drive 1 into the receiving openings 2.1 of the conveyor belt 2.9 on the respective inner surface 2.8 in the transport elements 2 and via the concentric gear motor 5. The spatially square or cylindrical transport box 7, which can be closed on both sides and is guided in the free space 6 and has a rotatable top part 7.1 and a base part 7.2, is connected to the carriage 3 in a continuously vertical position by connecting elements 4, wherein it is held by the connecting elements 4 and is spirally and simultaneously vertically movable within the free space 6.
