Technical Field

[0001] The present invention relates to a track module for a linear motor conveying system, a linear motor conveying system and a method for manufacturing the track module. The linear motor conveying system comprises one or more track modules and one or more carriers to be guided in the one or more track modules. Background Art

[0002] Linear conveyor systems, such as linear motor conveyor systems, are used in various applications, for example in industrial applications. For example, they are used in the field of high-speed conveyor solutions for transport within and between machines. Such solutions include inverted linear motor systems, which can precisely and dynamically control small workpiece carriers. The carriers themselves can be passive. Summary of the Invention

[0003] According to the invention, a track module, a linear motor conveying system and a method for producing a track module are proposed having the features of the independent claims. Advantageous embodiments are the subject matter of the dependent claims and the following description.

[0004] The present invention relates to a linear motor conveying system and a track module used therein. Such a linear motor conveying system comprises one or more track modules and one or more carriers to be guided in the one or more track modules. The track modules can be standardized modules, several of which can be connected to each other to form a track system. For example, the track module has or defines at least one conveying path, i.e. the path along which the carrier module is guided and moved. These track modules can be of different types, such as straight modules, curved modules and switch modules. Depending on specific requirements, the required number of such different modules can be connected to form a track system. While straight modules and curved modules usually have one conveying path, a switch module can have at least two conveying paths, or one conveying path divided into two conveying paths.

[0005] The present invention relates in particular to track modules having a curved track geometry, i.e., track modules in which at least a portion of the track guiding the vehicle is curved rather than straight. Such track modules are in particular curved modules and switch modules (e.g., a switch module may have both straight and curved track sections).

[0006] One embodiment of the present invention relates to such a track module. The track module comprises a track component and the track module has a curved track geometry as explained above. The track module further comprises at least two support structures, preferably rods. Each support structure is configured to serve as one of at least two bearing surfaces for a wheel, preferably a wheel of the carrier module. Each of the at least two support structures is arranged in a corresponding one of the at least two recesses of the track component. Furthermore, the at least two support structures are made of a harder material than the track component. In one embodiment, the track component is made of aluminum, preferably extruded aluminum. In one embodiment, the at least two support structures are made of steel, preferably hardened steel.

[0007] In a linear motor conveyor system, multiple carrier modules move within a track module or several connected track modules, using wheels to support the weight of the carrier modules, the payload, and any forces acting on the carrier modules. Within a linear motor conveyor system, the carrier modules can be moved through curves or lane changes. The wheels of the carrier modules need to run on a surface (support surface) that can withstand high forces while also providing a long service life for the guidance system (track module). This has proven to be achieved by making the wheel contact surfaces from hard materials such as (hardened) steel or (hardened) stainless steel. However, making the entire track module from such materials would be prohibitively expensive and difficult to manufacture. Therefore, the track components can be made from other, less hard materials, such as aluminum. Thus, an aluminum base frame can be used with (hardened) stainless steel inlays (support structures or rods) as the running or support surface. The track components can also be formed as a single piece. It is important to note that the track components can be constructed with struts, etc., to further reduce weight and increase stability.

[0008] This allows for lightweight and easy production of the track components (base frame) and also a strong running surface for the carrier wheels, which provides a long service life. Both advantages are achieved in curves and switches.

[0009] It is to be noted that track modules having a straight geometry, ie track modules of the straight module type, may also have such a support structure in such a recess of the track component.

[0010] In one embodiment, the track component includes a first side portion, a second side portion, and a bottom portion along at least a portion of the conveyor path, wherein the first side portion and the second side portion are arranged relative to each other. The bottom portion is preferably configured to rest on and / or be oriented toward and / or be mounted to a ground surface. Thus, the bottom portion may be oriented substantially horizontally, and the first and second side portions may be oriented substantially vertically. The track component may be U-shaped, for example, when viewed in a cross-section through the conveyor path or along the conveyor path (wherein the first and second side portions are legs of the U-shape).

[0011] At least a first of the at least two supporting surfaces is arranged at the first side portion, and at least a second of the at least two supporting surfaces is arranged at the second side portion, so that the at least one first supporting surface and the at least one second supporting surface face each other. The track module may also include more than two supporting surfaces, for example, two or three first supporting surfaces and two or three second supporting surfaces. This requires more than two support structures. The number of supporting surfaces should generally match the number and / or arrangement of the wheels of the carrier module.

[0012] Such a track module, having two side sections, allows for receiving a carrier module between a first side section and a second side section. Such a carrier module may include at least two wheels. In one embodiment, the track module is configured such that the at least one first support surface mates with at least a first wheel of the carrier module, and the at least one second support surface mates with at least a second wheel of the carrier module. If more support surfaces are provided on the track module, more corresponding wheels may be provided on the carrier module. With respect to support surfaces and wheels, mate means that the wheels can be guided by and roll on the corresponding support surfaces.

[0013] In one embodiment, the track module further comprises two electromagnetic motor components, each of which preferably comprises one or more electrical coils. A first electromagnetic motor component of the two electromagnetic motor components is arranged at a first side portion, and a second electromagnetic motor component of the two electromagnetic motor components is arranged at a second side portion, such that the first electromagnetic motor component and the second electromagnetic motor component face each other. Preferably, the track module is configured such that the first electromagnetic motor component mates with a first corresponding electromagnetic motor component of the carrier module, the first corresponding electromagnetic motor component preferably comprising one or more permanent magnets, and the second electromagnetic motor component mates with a second corresponding electromagnetic motor component of the carrier module, the second corresponding electromagnetic motor component preferably comprising one or more permanent magnets.

[0014] In one embodiment, the first electromagnetic motor component is fixed to the first side part by means of gluing and / or screwing, and / or the second electromagnetic motor component is fixed to the second side part by means of gluing and / or screwing. This allows for simple, fast and safe fixing.

[0015] In one embodiment, the bottom portion includes one or more holes facing the ground surface. This allows small debris to be removed. In addition, it also allows water to be drained when used in an IP65 type environment, for example.

[0016] Another embodiment of the present invention relates to a linear motor conveyor system comprising one or more track modules as described above, and one or more carrier modules to be received and guided within the one or more track modules. Each of the carrier modules is received or receivable within the track module or modules, wherein each of the carrier modules comprises a carrier component and at least two wheels. Suitable connection means (e.g., screws or a form fit) may be provided for mechanical connection of the track modules. Furthermore, electrical connections for the electromagnetic motor components should be provided.

[0017] In one embodiment, the linear motor transport system further comprises a control system for controlling the linear motor transport system to move the carrier or each of the carriers within the one or more track modules. This may include controlling (and energizing) the electromagnetic motor components, such as coils, of the track modules in an appropriate manner.

[0018] Such a carrier module may include a carrier member and at least two wheels. The carrier module may be configured to be received between a first side member and a second side member of a track module (such as the track module described above). At least a first wheel of the two wheels and at least a second wheel of the two wheels are arranged relative to each other on the carrier member such that, when received in the track module, the at least one first wheel faces the first side member and the at least one second wheel faces the second side member.

[0019] In one embodiment, the carrier module may further include two corresponding electromagnetic motor components. A first corresponding electromagnetic motor component of the two corresponding electromagnetic motor components and a second corresponding electromagnetic motor component of the two corresponding electromagnetic motor components are arranged opposite each other at the carrier component, such that when received in the track module, the first corresponding electromagnetic motor component faces the first electromagnetic motor component of the track module, and the second corresponding electromagnetic motor component faces the second electromagnetic motor component of the track module.

[0020] Another embodiment of the present invention relates to a method for manufacturing a track module for a linear motor conveyor system, preferably the track module is a track module as described above. The track module has a curved track geometry. The method comprises the following steps. A track component is provided, wherein the track component comprises at least two recesses and preferably has a curved geometry. At least two support structures are provided, preferably rods. Preferably, at least one of these support structures is provided with a curved geometry (i.e. the rod is curved). Each of these support structures is intended to serve as one of at least two bearing surfaces for a wheel. The at least two support structures are made of a harder material than the track component. For example, the at least two support structures are made of (hardened) steel or stainless steel and the track component is made of aluminum. Each of the at least two support structures is arranged in a corresponding one of the at least two recesses.

[0021] The track components (which take the form of profiles) can be extruded from aluminum. They are produced by heating an aluminum ingot and pushing it through a specially designed die. This die should have the contours of the track component (base frame), within which the support structure (e.g., stainless steel inlays) can be arranged or placed. To create an appropriate interface for the support structure, a recess (or cavity) can be milled after extrusion to accommodate the support structure. The support structure can be pushed into this recess and clamped in place by the aluminum extrusion.

[0022] In one embodiment, a track component having a curved geometry is provided by manufacturing the track component with a straight geometry, preferably by extrusion. The track component is then bent to obtain the curved geometry. The desired form or radius of the curved geometry can be selected, for example, depending on whether a curved module or a switch module is being manufactured.

[0023] In a further embodiment, the rail component with the curved geometry is provided in that the rail component is directly produced with the curved geometry, preferably by means of milling.

[0024] Both embodiments for obtaining curved geometries have specific advantages. The embodiment for the curved track part has an easier and faster manufacturing of the track part. The embodiment for directly manufacturing the curved geometry may provide for a more precise shaping of the recess.

[0025] In another embodiment, the track member may be configured as a straight track member, and the at least two support structures may be configured as straight support structures. Each of the straight support structures may be disposed in a corresponding one of the at least two recesses of the straight track member. Thereafter, the track member and at least one of the at least two support structures are bent together.

[0026] Further advantages and embodiments of the invention are apparent from the description and the drawings.

[0027] It goes without saying that the features mentioned above and those still to be explained below can be used not only in the combination specified in each case but also in other combinations or on their own, without departing from the scope of the present invention.

[0028] The invention is schematically illustrated using exemplary embodiments in the drawings and is described in detail below with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] Figure 1 A linear motor conveyor system 100 according to an embodiment is schematically illustrated in perspective view. As an example, the linear motor conveyor system 100 includes several track modules. Depending on the specific application requirements of the linear motor conveyor system, different types and quantities of track modules can be provided, and the track modules can be connected to each other to form a track system. Examples of track modules include straight modules, curved modules, and switch modules.

[0031] As an example, two track modules 101 are straight modules and four track modules 102.1, 102.2, 102.3, 102.4 are curved modules. Figure 1 In the example shown in FIG, the straight modules 101 are both identical. However, it is noted that the straight modules can have different lengths, wherein the lengths vary along the conveying path P (for Figure 1 The straight module 101 is shown in the moving or conveying direction.

[0032] exist Figure 1 In the example shown, bending modules 102.1, 102.2, 102.3, and 102.4 are different from one another. For example, bending modules 102.1, 102.2, 102.3, and 102.4 have different radii and / or curved shapes. However, it should be noted that these four different bending modules are merely illustrative. Different bending modules with different radii and / or shapes may be provided as needed. However, these bending modules all have in common that they provide, or in particular, only provide, a curved track.

[0033] Will describe in more detail Figure 1 The straight module 101 at the lower left side of the middle. The track module 101 includes a track component and at least two support surfaces 131, 132. As an example, Figure 1 Six bearing surfaces are shown in FIG, but only two of them are indicated with reference numerals.

[0034] Furthermore, the rail member includes a first side portion 111, a second side portion 112, and a bottom portion 113, wherein the first side portion 111 and the second side portion 113 are arranged opposite each other. As an example, the rail member and each of the first side portion 111, the second side portion 112, and the bottom portion 113 are formed to have a structure with struts or ribs, rather than an all-material structure. This allows for the use of less material while still providing a stable structure.

[0035] At least a first supporting surface of the at least two supporting surfaces (here, for example, supporting surface 131) is arranged at the first side portion 111 or is formed integrally with the first side portion 111, and at least a second supporting surface of the at least two supporting surfaces (here, for example, supporting surface 132) is arranged at the second side portion 112 or is formed integrally with the second side portion 112, so that the at least one first supporting surface 131 and the at least one second supporting surface 132 face each other.

[0036] By way of example, these bearing surfaces are formed by support structures, such as rods, which are arranged in or inserted into recesses in the first and second side parts 111, 112. However, in general, such bearing surfaces can also be formed by the first and second side parts 111, 112, for example by having a specific shape.

[0037] It should be noted that this way of forming track modules is not only applicable to the straight module 101, but also to other types of modules, such as curved modules 102.1, 102.2, 102.3, 102.4.

[0038] Figure 1 Each of the straight and curved modules shown in FIG. 1 has a conveying path from a respective first end to a respective second end, although only one straight module 101 is shown. When the track modules are connected to each other, the individual track paths also connect to form a cumulative conveying path along which the carrier module is guided and conveyed. Note that the carrier module can be moved or conveyed in both directions of the conveying path, as indicated by the arrows indicating the conveying path P.

[0039] Furthermore, as an example, the linear motor transport system 100 includes several carrier modules 150 ( Figure 1 Six carrier modules are shown, of which only one is indicated by a reference numeral). The track module 101 is configured to receive such a carrier module 150 between the first side portion 111 and the second side portion 112, in particular such that the at least one first bearing surface 131 mates with at least a first wheel of the carrier module 150 and such that the at least one second bearing surface 132 mates with at least a second wheel of the carrier module 150. Figure 1 shown in the figure, but will be referred to later. Figures 3a to 3c Illustrated and described in more detail.

[0040] Furthermore, in one embodiment, the linear motor transport system 100 includes a control system 190 for controlling the linear motor transport system 100 to move the carrier module 150 within the track modules 101, 102.1, 102.2, 102.3, 102.4, i.e., along the track modules 101, 102.1, 102.2, 102.3, 102.4. Figure 1 The linear motor conveying system 100 is operated in the direction of movement or conveying R indicated in FIG. It should be noted that the conveying direction R is a straight line for the straight modules, but a curve for the curved modules. In order to operate the linear motor conveying system 100, it is necessary to control the electromagnetic motor components at the track modules, for example, by means of the control system 190. Such electromagnetic motor components are not Figure 1 shown in the Figure 3a 、 3b Shown in.

[0041] Figure 2A perspective view schematically illustrates a track module 203 according to an embodiment. The track module 203 is a switch module, i.e., a switch-type track module. Unlike a straight module or a curved module, the carrier module is not limited to moving from one of its two ends to the other, i.e., entering the track module at the first end and exiting the track module at the second end (thus having a single transport path). Instead, the carrier module can enter the switch module at the first end 215.1 and exit the switch module at the second end 215.3 or the third end 215.3. The switch module 203 has two transport paths P1 and P2, with transport path P2 diverting from transport path P1.

[0042] To control a linear motor conveying system including such a switch module, an electromagnetic motor component, for example, at the track module (not shown here), is controlled so that the carrier module is moved to the second end 215.2 or the third end 215.3, so that the carrier module exits using conveying path P1 at the second end 215.2 or the third end 215.3 using conveying path P2. If the carrier module enters the switch module at the second end 215.2 or the third end 215.3, in both cases, the carrier module will exit the switch module 203 at the first end 215.3. In other words, the two conveying paths P1 and P2 merge.

[0043] and Figure 1 Similar to the straight and curved modules shown in FIG, the switch module 203 includes a track component for a conveying path (eg, P1). The switch module 203 also includes at least two support surfaces 231, 232. As an example, Figure 2 Six bearing surfaces are shown in FIG, but only two of them are indicated with reference numerals.

[0044] Furthermore, the rail member includes a first side portion 211, a second side portion 212, and a bottom portion 213 along conveying path P1, wherein the first side portion 211 and the second side portion 213 are arranged opposite each other. Note that due to the turn of conveying path P2, the second side portion 211 is interrupted along conveying path P1. Similar to conveying path P1, the rail member includes a first side portion, a second side portion, and a bottom portion (not indicated by reference numerals here) along conveying path P2.

[0045] As an example, with Figure 1 Unlike the track module shown in , the track member and each of the first side portion 211, the second side portion 212 and the bottom portion 113 are formed with a full material structure. Depending on how the support surfaces are formed (e.g., their inclination), the wheels of the carrier module may need to have a corresponding inclination or arrangement.

[0046] At least a first supporting surface of the at least two supporting surfaces (here, for example, supporting surface 231) is arranged at the first side portion 211 or is formed integrally with the first side portion 211, and at least a second supporting surface of the at least two supporting surfaces (here, for example, supporting surface 232) is arranged at the second side portion 212 or is formed integrally with the second side portion 212, so that the at least one first supporting surface 231 and the at least one second supporting surface 232 face each other.

[0047] As an example, and with Figure 1 , these support surfaces are formed by the first side portion 211 and the second side portion 212 by having a specific shape or geometric configuration. However, such a turnout module may also include a Figure 1 The support surface formed by the track module shown in FIG. In addition, such a switch module may also include a Figure 1 The track modules shown in FIG are formed, ie formed, as track components with a strut or rib structure.

[0048] like Figure 2 The turnout module shown in FIG can be used with Figure 1 The straight modules shown in are used together with curved modules in order to create (complex) track systems and linear motor conveyor systems. It should be taken into account that the bearing surfaces of the different track modules should be of the same type.

[0049] Figure 3a A track module 301 and a carrier module 350 according to an embodiment are illustrated in a perspective view. Figure 3b The cross-section in the xy plane is shown Figure 3a track module 301 and carrier module 350 . Figure 3c A perspective view Figure 3a The carrier module 350 is not included in the track module. Figure 3a 、 3b , 3c.

[0050] As an example and to explain the basic structure and composition of the track module, the track module 301 is a straight module. The track module 301 may correspond to Figure 1 The track module 101 of FIG. 1 is shown, however, with additional components. The following explanation is also applicable to other types of track modules.

[0051] The track module 301 comprises a track component 310 and six supporting surfaces 331.1, 331.2, 331.3, 332.1, 332.2, 332.3 as an example. In addition, the track component 301 comprises a first side portion 311, a second side portion 312 and a bottom portion 313 along a conveying path, wherein the first side portion 311 and the second side portion 312 are arranged opposite each other. The conveying path is not marked in FIG3 but extends in the y direction and can be connected to Figure 1 The conveying path P shown in FIG is similar or identical to that in FIG.

[0052] By way of example, the rail member 310 and each of the first side portion 311, the second side portion 312, and the bottom portion 313 are formed to have a structure with struts or ribs, rather than a solid structure. This allows for the use of less material while still providing a stable structure. For example, a portion of the bottom portion 313 and each of the first side portion 311 and the second side portion 312 may have a double-walled structure with a supporting rib between the two walls.

[0053] Three first bearing surfaces (here, for example, bearing surfaces 331.1, 331.2, 331.3) are arranged on or integrally formed with first side portion 311, and three second bearing surfaces (here, for example, bearing surfaces 332.1, 332.2, 332.3) are arranged on or integrally formed with second side portion 312, such that first bearing surfaces 331.1, 331.2, 331.3 and second bearing surfaces 332.1, 332.2, 332.3 face each other, i.e., are oriented toward each other. In other words, all bearing surfaces are provided on the inner side of the respective first and second side portions forming the conveying path.

[0054] By way of example, these bearing surfaces are formed by support structures, such as rods, which are arranged in or inserted into recesses in the first side portion 311 and the second side portion 312. However, in general, such bearing surfaces can also be formed by the first side portion 311 and the second side portion 312, for example by having a specific shape.

[0055] In one embodiment, track 301 further includes two electromagnetic motor components, namely a first electromagnetic motor component 340.1 and a second electromagnetic motor component 340.2. First electromagnetic motor component 340.1 and second electromagnetic motor component 340.2 extend along the conveying path (here: in the y-direction). First electromagnetic motor component 340.1 is arranged at first side portion 311, and second electromagnetic motor component 340.2 is arranged at second side portion 312, such that first electromagnetic motor component 340.1 and second electromagnetic motor component 340.2 face each other.

[0056] In one embodiment, first electromagnetic motor component 340.1 includes one or more electrical coils 341.1; the number of such coils may depend on how the coils are manufactured. Furthermore, first electromagnetic motor component 340.1 may include one or more magnetic or ferromagnetic cores or structured magnetic cores 342.1, made, for example, of iron. Such magnetic or ferromagnetic cores increase the magnetic force generated by the electrical coils. Furthermore, first electromagnetic motor component 340.1 may include a retaining or fixing structure 343.1 for securing the coils and magnetic cores to first side portion 311. First electromagnetic motor component 340.1 may be secured to first side portion 311, for example, by gluing and / or screwing.

[0057] Similarly, second electromagnetic motor component 340.2 includes one or more electrical coils 341.2; the number of such coils may depend on how the coils are manufactured. Furthermore, second electromagnetic motor component 340.2 may include one or more magnetic or ferromagnetic cores or structured magnetic cores 342.2, made, for example, of iron. Such magnetic or ferromagnetic cores increase the magnetic force generated by the electrical coils. Furthermore, second electromagnetic motor component 340.2 may include retaining or fixing structures 343.2 for securing the coils and magnetic cores to second side portion 312. Second electromagnetic motor component 340.2 may be secured to second side portion 312, for example, by gluing and / or screwing.

[0058] In one embodiment, the bottom portion 313 is configured to be placed on and / or oriented toward and / or mounted to a ground surface. Figure 3a 、 3b When viewed in the z-direction, the floor surface will be below the bottom portion 313. In one embodiment, the bottom portion 313 includes one or more holes 314 facing the floor surface. This allows for the removal of small debris. It also allows for the drainage of any fluids, such as water, when used in an IP65 environment, for example.

[0059] The track module 301 is configured to receive the carrier module 350 between the first side portion 311 and the second side portion 312, and is preferably configured so that the first supporting surfaces 332.1, 332.2, 332.3 match the corresponding first wheels of the carrier module 350, and so that the second supporting surfaces 332.1, 332.2, 332.3 match the corresponding second wheels of the carrier module 350.

[0060] Although Figure 3a 、 3b The carrier module 350 is shown received in the track module 301, but Figure 3c Such a carrier module 350 is shown. Figure 3cSix bearing surfaces 331.1, 331.2, 331.3, 332.1, 332.2, 332.3 are shown (in this example, these are rods). The carrier module 350 comprises a carrier part 353 and, as an example, six wheels, namely three first wheels 351.1, 351.2, 351.3 and three second wheels 352.1, 352.2, 352.3 (note that wheel 352.2 is Figure 3c The carrier module 350 is configured to be received between the first side portion 311 and the second side portion 312 of the track module 301 .

[0061] As an example, three first wheels 351.1, 351.2, 351.3 and three second wheels 352.1, 352.2, 352.3 are arranged opposite one another at the carrier part 353 so that when received in the track module 301, the three first wheels 351.1, 351.2, 351.3 face the first side part 311 and the three second wheels 352.1, 352.2, 352.3 face the second side part 312. This can be Figure 3a 、 3b Each of the wheels 351.1, 351.2, 351.3, 352.1, 352.2, 352.3 matches a corresponding one of the six bearing surfaces 331.1, 331.2, 331.3, 332.1, 332.2, 332.3. This can be seen in Figure 3c As seen in [1] . With respect to bearing surfaces and wheels, matching means that the wheel can be guided by and roll on the corresponding bearing surface. Therefore, the bearing surface can also be called a rolling surface. For example, these wheels may include grooves that match the bearing surface.

[0062] In one embodiment, the carrier module 350 further includes two corresponding electromagnetic motor components, namely a first corresponding electromagnetic motor component 356 ( Figure 3c ) and a second corresponding electromagnetic motor component ( Figure 3c ). For example, each of such corresponding electromagnetic motor components may include one or more permanent magnets. The first corresponding electromagnetic motor component 356 and the second corresponding electromagnetic motor component 356 are arranged opposite each other at the carrier component 353 so that when received in the track module 301, the first corresponding electromagnetic motor component 356 faces the first electromagnetic motor component 340.1 of the track module 301 and the second corresponding electromagnetic motor component faces the second electromagnetic motor component 340.2 of the track module 301. This can be Figure 3a Seen in.

[0063] First corresponding electromagnetic motor component 356 mates with first electromagnetic motor component 340.1, i.e., the two components electromagnetically interact with each other to form a linear electromagnetic motor. This typically requires an appropriately sized air gap between the two components. Similarly, second corresponding electromagnetic motor component 356 mates with second electromagnetic motor component 340.2, i.e., the two components electromagnetically interact with each other to form a linear electromagnetic motor. This typically requires an appropriately sized air gap between the two components. Thus, track module 301 allows for a suspended state of carrier module 350 to be received between the two side portions of track module 301; this reduces cogging.

[0064] Figure 4a A track module 402 is schematically illustrated at a stage of a manufacturing process according to an embodiment. Figure 4b Schematically illustrates another stage of the manufacturing process Figure 4a Track module 402. Track module 402 includes track component 410 and has a curved track geometry. For example, track module 402 can be or can correspond to a curved module, such as Figure 1 Any one of the bending modules 102.1, 102.2, 102.3, 102.4 shown in FIG. Figure 1 、 3a As mentioned in FIG3b, the structure of the curved module can be substantially the same as that of the straight module, except that it has a curved geometry instead of a straight geometry. Therefore, the track module 402 has similar or identical parts or components as the straight module.

[0065] Rail member 410 includes a first side portion 411, a second side portion 412, and a bottom portion 413, wherein first side portion 411 and second side portion 412 are arranged opposite each other. As an example, rail member 410 and each of first side portion 411, second side portion 412, and bottom portion 413 may be formed with struts or ribs, rather than a solid structure. This allows for the use of less material while still providing a robust structure. For example, rail member 410 may have a height h (here, along the z-direction) and a width w (here, along the x-direction).

[0066] Figure 5 A method for manufacturing a track module (such as track module 401) according to an embodiment is schematically illustrated in a flow chart. In the following, Figures 4, 4a and 5 will be described together.

[0067] In step 500, a track member 410 is provided. As an example, the track member 410 has a curved geometry and includes six recesses 416.1, 416.2, 416.3, 417.1, 417.2, 417.3. Three first recesses 416.1, 416.2, 416.3 are provided on a first side portion 411, and three recesses 417.1, 417.2, 417.3 are provided on a second side portion 412. The track member 410 may be made of aluminum.

[0068] In step 510, six support structures, preferably rods, are provided as an example. Figure 4b In FIG. 4 , six rods 418 are shown in the recess, with only one of these rods being indicated by a reference numeral. Note that these support structures or rods 418 may correspond to Figure 1 、 3a , 3b, 3c, and wherein these support structures or rods are described as forming a support surface. Similarly, each of the rods 418 is intended to serve as a support surface for a wheel. One or more or all of the support structures or rods 418 have a curved geometry, as it is intended to have in the final curved module, such as Figure 1 The support structure can be made of (hardened) steel or (hardened) stainless steel. Generally speaking, the support structure should be made of a harder material than the track components.

[0069] In one embodiment, providing the track member 410 with a curved geometry includes manufacturing the track member 410 with a straight geometry, preferably by extrusion, in step 502. This may be similar to Figure 3a The geometry of the track member 310 shown in FIG. For example, the track member 410 (which has the form of a profile) can be extruded from aluminum. The track member 410 can be produced by heating an aluminum ingot and pushing the heated ingot through a specially designed mold. The mold should have the contour of the track member 410, in which the support structure (e.g., stainless steel inlay) can be arranged or placed. These are Figure 4a To create a suitable interface for the support structure, a recess (or cavity) where the support structure is to be placed can be milled after extrusion.

[0070] In step 504, the rail component (having a straight geometry) is bent to obtain a rail component having a curved geometry. For example, a suitable tool or machine for bending can be used. For example, the desired form or radius of the curved geometry can be selected depending on whether or which curved module is to be manufactured. Figure 1 As seen in the figure, different bending modules are available.

[0071] In another embodiment, in step 506, the rail component 410 is directly manufactured with the curved geometry, preferably by means of milling. For example, suitable tools or machines for machining or milling can be used. Also, for example, the desired form or radius of the curved geometry can be selected depending on whether or which curved module is manufactured. As can be seen in Figure 1 As seen in the figure, different bending modules are available.

[0072] Each of the support structures 418 is placed in a corresponding one of the recesses in step 520. The support structures may be pushed into the recesses and clamped in place by an aluminum extrusion.

[0073] The resulting track module 401 comprises a track component 410 comprising said recess. Furthermore, the track module 401 comprises support structures, preferably rods, each of which is configured as one of at least two bearing surfaces for a wheel, and each of the support structures is arranged in a respective one of the recesses, as may be seen in FIG. Figure 4b The support structure is made of a stiffer material than the track member 410. Additionally, for example, the track module 401 may include an electromagnetic motor component as described above with respect to the track module 301; this also applies to the bending module.

[0074] Figure 6a A track module 604 according to an embodiment is schematically illustrated in a perspective view. Figure 6b The diagram shows the Figure 6a The track module will be described below. Figure 6a 、 6b As mentioned above, different types of track modules may be provided, such as straight modules, curved modules, and switch modules. Track module 604 is another type of track module.

[0075] Track module 604 includes a track member 610 and at least two support surfaces; as an example, two support surfaces are shown, namely a first support surface 631 and a second support surface 632. The basic structure or form of track module 604 can be similar to Figure 1 Track Module 101 or Figure 3a 、 3b However, unlike these track modules 101, 301, the track member 610 does not have a support or rib structure, but is made of a solid material, similar to Figure 2 The switch module 203 shown in FIG.

[0076] Correspondingly, the support surface is similar to Figure 2 The support surface of the turnout module 203 shown in FIG. The arrangement of the wheels of the carrier module (such as the carrier module 650) can be tilted. However, it should be noted that the arrangement of the track components and the support surface can also be as shown in FIG. Figure 1 Track Module 101 or Figure 3a 、 3b One of the track modules 301 has a support or rib structure.

[0077] Track module 610 includes a first side portion 611, a second side portion 612, and a bottom portion 613. For example, a first support surface 631 is disposed on or integrally formed with first side portion 611, and a second support surface 632 is disposed on or integrally formed with second side portion 612. In one embodiment, track module 610 further includes two electromagnetic motor components, namely, a first electromagnetic motor component 640.1 and a second electromagnetic motor component 640.2. The first electromagnetic motor component 640.1 and the second electromagnetic motor component 640.2 extend along the conveying path (here, in the y-direction). The first electromagnetic motor component 640.1 is disposed on the first side portion 611, and the second electromagnetic motor component 640.2 is disposed on the second side portion 612, such that the first electromagnetic motor component 640.1 and the second electromagnetic motor component 640.2 can face each other.

[0078] The first and second electromagnetic motor components may be constructed similarly to Figure 3a 、 3b Shown in and about Figure 3a 、 3b The structure of the track module 301 described in FIG. For example, each electromagnetic motor component may include one or more electrical coils.

[0079] Furthermore, the track module 610 includes a static module portion 661 and a movable module portion 612. The movable module portion 662 includes at least a portion 611' of the first side portion 611 and at least a portion 631' of the first support surface 631. In one embodiment, the movable module portion 661 includes at least a portion 640.1' of the first electromagnetic motor component 640.1.

[0080] The movable module portion 661 is movable relative to the static module portion 662 between a closed state and an open state. Figure 6a The closed state is shown in Figure 6b In the closed state, the first side portion 611 and the second side portion 612 are arranged relative to each other so that the first support surface 631 and the second support surface 632 face each other, in particular along the entire length of the conveying path or track module 604. In this closed state, the track module 604 behaves like Figure 1 Track Module 101 or Figure 3a 、 3b The track module 301 is a straight module.

[0081] However, when in the open state, part 611 ′ of the first side portion 611 , part 631 ′ of the first support surface 631 and part 640 . 1 ′ of the first electromagnetic motor component 640 . 1 are moved away to allow free access to the inside of the track module for inserting and / or removing the carrier module 650 .

[0082] In one embodiment, the movable module portion 661 is hingedly connected to the static module portion 662, for example, via a hinge mechanism 670. In one embodiment, the movable module portion 661 also includes a portion 613' of the bottom portion 613 to allow for better access. In one embodiment, the movable module portion 661 is movable downwardly on the hinge for moving it from a closed state to an open state. Figure 6b As shown in FIG, the movable module portion 661 moves downward (or folds) according to the hinge.

[0083] In one embodiment, the track module 604 further includes a locking mechanism 671 configured to lock or secure the movable module portion 662 relative to the static module portion 661 when in a closed position.

[0084] Figure 7 The method for operating a linear motor conveyor system according to an embodiment is schematically illustrated in a flow chart. Such a linear motor conveyor system may include several track modules, such as Figure 1 Furthermore, the linear motor transport system 100 comprises at least one track module having a movable module portion, such as Figure 6a 、 6b Track module 604.

[0085] In order to insert the carrier module into the track module, the following steps may be performed: In step 700, the movable module part is moved to an open state relative to the static part if it is not already in an open state; this may be as follows: Figure 6a The situation shown in Figure 6b In step 702 the carrier module is inserted into the track module and in step 704 the movable module part is moved again into the closed state relative to the static part. Then, usual operation is possible.

[0086] To remove the carrier module from the track module, the following steps may be performed: In step 710, the movable module portion is moved to an open position relative to the static portion if not already in an open position; this may be as follows: Figure 6a The situation shown in Figure 6bIn step 712, the carrier module is removed from the track module and in optional step 714, the movable module part is moved to a closed state relative to the static part. This step is required when other carrier modules will still be moved in the linear motor transport system.
