Description

Technical Field

[0001] This invention relates to a roll shuttle and a suspended roll shuttle, specifically in combination with the suspended roll shuttle, and more specifically in combination with the operation of a frame system and a conveying system for handling the rolls. Background Technology

[0002] In existing storage systems, forklifts and stacker cranes form the basis for inserting and removing items from storage areas. However, this type of forklift and stacker crane typically requires a considerable amount of space and is limited in terms of storage flexibility.

[0003] Furthermore, known forklifts typically require a considerable amount of maneuvering space, which reduces the available storage capacity. Summary of the Invention

[0004] In view of the above statements, the technical problem of the present invention is to improve the flexibility and workload of roller storage and conveying systems.

[0005] According to the present invention, this problem is solved by a roller shuttle for conveying rollers in a rack system, the roller shuttle comprising: a base frame on which wheels are mounted to allow the roller shuttle to move along a travel guide laid in the storage plane of the rack system; a running slide mounted on the base frame to be movable in one direction relative to the travel direction of the roller shuttle, the direction deviating from the travel direction of the roller shuttle by a predetermined angle greater than zero; and a loading mandrel for conveying at least one roller to be stored, the loading mandrel being pivotally fixed to the running slide in a plane substantially parallel to the storage plane of the rack system, wherein the loading mandrel is equipped with a chain conveyor to position the roller to be stored along the loading mandrel.

[0006] Furthermore, this technical problem is solved by a suspended roller shuttle for conveying the rollers, which is used to transport the rollers along the suspended guide system and through distribution stations to different receiving and distribution points (which are combined with multiple suspended guides), as well as for further transport between or within a rack system.

[0007] Furthermore, the stated technical problem is solved by a rack system for storing and conveying rollers, wherein at least one roller shuttle according to the invention is present, and preferably a suspended roller shuttle according to the invention is also present, for intermediate conveying between the described different positions.

[0008] Finally, this technical problem was solved by the method used to operate the rack system.

[0009] Within the scope of this invention, rollers can be inserted into or removed from a storage area at one or more depths using a mandrel system. For this purpose, the mandrel system is equipped with a chain conveyor and preferably includes stops to ensure orderly positioning of the rollers during conveying and storage.

[0010] By appropriately designing the length of the mandrel system, one or more depths of the rollers within the frame system can be manipulated. Within the scope of this invention, the mandrel system can be designed as a roller shuttle or a suspended roller shuttle. In the case of a roller shuttle, the mandrel system is movably and pivotally mounted on the base frame, while in the case of a suspended roller shuttle, the mandrel system is mounted on a suspended slider that can be pushed back and forth on a travel guide.

[0011] Preferably, multiple rollers with increasing diameters or multiple rollers of the same diameter are positioned on the mandrel system such that the rollers can be received and processed through a sleeve at the center of the rollers.

[0012] Furthermore, it should be noted that in the case of roller shuttles, the dual mounting of the spindle system (i.e., movable in the lateral direction relative to the travel direction of the base frame, and pivotable relative to the spindle's suspension) allows for the handling of the spindle system, ensuring that even when the spindle pivots from one side of the base frame to the opposite side, it is always guided and does not extend beyond the side of the base frame. This makes the roller shuttle design particularly compact and allows for overlapping operating modes, in which the roller shuttle can move longitudinally while simultaneously changing the position of the rollers relative to the storage area.

[0026] Figure 12 Further construction of some components of the shelving system according to the invention is shown by way of example. Detailed Implementation

[0027] Figure 1 This is a perspective view of the roller shuttle according to the present invention.

[0028] like Figure 1 As shown, the roller shuttle 10 according to the invention for conveying rollers in a rack system includes a base frame 12 on which wheels 14-1, ... 14-3 are mounted to enable the roller shuttle to move along a travel guide laid in the storage plane of the rack system.

[0029] like Figure 1As shown, the roller shuttle 10 according to the invention includes a running slide 16 mounted on a base frame 12, such that the running slide is movable relative to the direction of travel of the roller shuttle. The roller shuttle 10 can move in one or more planes for each case, wherein, in the latter case, the roller shuttle can be offset between different planes by a shuttle repositioning device, so that it can serve the shelving system even with only a small number of roller shuttles 10. Furthermore, the roller shuttle 10 can also travel or run outside the shelving system. For this purpose, the roller shuttle is placed on a travel rail outside the shelving system by a vertical repositioning device, or the roller shuttle is traveled outward from the shelving system via a rail extension to serve a transfer station. At this transfer system, rollers are transferred to or removed from the shelving system.

[0030] Typically, the running slide 16 is movable such that its direction of movement deviates from the travel direction of the roller shuttle 10 by a predetermined angle greater than zero (e.g., 90 degrees). Therefore, the running slide 16 is preferably movable laterally relative to the travel direction of the base frame 12.

[0031] like Figure 1 As shown, the running slider 16 may include a base plate 18 on which various components may be mounted. The base plate 18 moves along the vertical frame of the running slider, for example, via a chain conveyor. For this purpose, an electric motor 20 may be provided to drive the running slider.

[0032] like Figure 1 As shown, the roller shuttle 10 according to the invention further includes a load mandrel 22 for conveying at least one roller to be stored. Within the scope of the invention, the load mandrel 22 is pivotally fixed to the running slide 16, specifically in a plane extending substantially parallel to the base surface of the frame or the storage plane of the shelving system.

[0033] like Figure 1 As shown, the loading mandrel 22 also includes a chain conveyor 24 through which one or more rollers can be received on the loading mandrel 22 and then lowered again.

[0034] like Figure 1As shown, the pivoting of the mounting spindle 22 is carried out by suitable carriers, such as two carrier plates 26 and 28, which are locked to the base plate of the running slider 16 in a dimensionally stable manner by supports 30 and 32.

[0035] Preferably, the loading spindle 22 according to the invention can be mounted on the running slide 16 so that its height can be adjusted, and the height can be changed, for example, by a suitable driven spindle 34 relative to the bottom surface of the base frame 12. This height-adjustable design of the loading spindle 22 simplifies the handling of the rollers when they are received and lowered by the loading spindle 22.

[0036] The length of the loading mandrel 22 is preferably designed such that it is an integer multiple of the width of the roller to be conveyed. Furthermore, a stop is preferably provided to secure the roller during conveying in the scaffold system.

[0037] Furthermore, preferably, at least one support roller and / or mating contact surface may be provided on the lower side of the base frame 12, so that when the loading spindle 22 pivots outward in the lateral direction relative to the roller shuttle 10, the surface tilting force can be introduced into the travel guide rail of the frame system through the support roller and / or mating contact surface.

[0038] Figure 2 It is used for explanation Figure 1 The diagram shows the operating mode of the roller shuttle.

[0039] like Figure 2 As shown, the operation of the roller shuttle 10 in the frame system can preferably be described by a coordinate system, wherein the travel direction forms the x-axis, the storage direction forms the y-axis, and the movement direction in the height direction forms the z-axis.

[0040] like Figure 2 As shown, for the operation of the roller shuttle 10, the positioning of the base frame has one degree of freedom based on the x_s coordinate. The y-position of the running slider relative to the base frame is described by y_s, and the height adjustment of the loading mandrel relative to the base frame is described by z_s. Another degree of freedom for the operation of the roller shuttle is the pivot angle α of the loading mandrel.

[0041] Assuming the length of the loading mandrel is L, the position of the tip of the loading mandrel can now be expressed by the following relationship:

[0042] x_d=x_s-L cos α

[0043] y_d=y_s+L sin α

[0044] Within the scope of this invention, it is intended to enable the superposition of the movement of the roller shuttle 10 in the x-direction and the synchronous pivoting of the loading mandrel 22 by operating the sliding member. In this case, the operating conditions are:

[0045] y_l <y_d<y_r

[0046] If we substitute the above relationship between x_d and y_d into the operating conditions and solve according to α, it is clear that the reliable pivot angle α depends on the positioning y_s of the loading mandrel 22 and the length L of the loading mandrel 22, according to:

[0047] arcsin [(y_l-y_s) / L]>α(y_s)>arcsin[(y_r-y_s) / L]

[0048] If this condition is met, the roller shuttle 10 can move parallel to the running direction of the slide rail, and at the same time the loading mandrel 22 can be positioned from one side to the other.

[0049] Typically, in the case of an instruction to insert or remove at least one roller from a storage area, this can be done by initially defining a first position and a second position along the travel guide within the scope of processing the instruction, so as to set the movement of the roller shuttle 10 in the x-direction.

[0050] Subsequently, during the longitudinal movement of the roller shuttle 10, for each case, the position y_s and pivot angle α of the loading mandrel 22 relative to the running slide, as well as the pivoting of the loading mandrel 22, can be controlled to satisfy the above conditions. The superposition of the longitudinal movement and the pivoting movement allows for a particularly efficient design of the operation time for inserting and removing the rollers from the storage area.

[0051] Figure 3 The diagram illustrates the operational state during the superposition of the longitudinal movement of the roller shuttle 10 and the repositioning of the loading spindle 22.

[0052] from Figure 3 It can be seen that when the above operating conditions are met during the longitudinal movement of the roller shuttle 10 along the slide rail, the running slide 16 moves continuously from one side of the roller shuttle 10 to the other side, while the loading spindle 22 pivots synchronously.

[0053] As described above, this achieves superposition of motion, thus ensuring particularly efficient handling of the rollers during insertion into or removal from the storage area of ​​the shelving system. At each point in time, it is ensured that during the longitudinal movement of the roller shuttle 10, the loading mandrel 22 does not protrude beyond the side of the roller shuttle 10 and thus come into contact with other components of the shelving system.

[0054] Figure 4 The operating modes of the roller shuttle 10 for storing rollers in a fixed storage box 36 or a movable storage box 38 at one or more depths are described.

[0055] like Figure 4 As shown, other operating states of the roller shuttle 10 according to the present invention involve the operations of actually inserting the roller into the storage area of ​​the rack system and removing the roller from the storage area of ​​the rack system.

[0056] like Figure 4 As shown, in this configuration, the shelving system may include a fixed storage box 36, which is fixedly mounted on the shelving system. Alternatively, the storage box may also be designed as a movable storage box 38, which can be positioned relative to the roller shuttle 10 by means of steering wheels parallel to and along the travel guide of the roller shuttle 10.

[0057] like Figure 4 As shown, the insertion or removal of rollers from the storage area (in the fixed storage box 36 or the movable storage box 38) is accomplished by the operating slider 16 and the loading mandrel 22. In this case, the operating slider 16 moves along the side edge of the roller shuttle 10 while the loading mandrel 22 pivots, positioning it above the storage box 36 or 38. Then, by adjusting the height of the operating slider 16 and the height of the loading mandrel 22, the rollers can be received onto the loading mandrel 22 via the chain conveyor 24, or conversely, the rollers can be transported from the loading mandrel 22 to the fixed storage box 36 or the movable storage box 38.

[0058] like Figure 4 As shown, the movable storage box 38 increases the flexibility of the storage system because even if the roller shuttle 10 is not moving, the movable storage box 38 can still allow the rollers to be inserted into and removed from the storage area as long as it moves correctly relative to the roller shuttle 10.

[0059] Figure 5 This is a perspective view of the roller shuttle 10 according to the present invention, wherein multiple rollers of different diameters are placed on the loading mandrel 22.

[0060] like Figure 5As shown, the loading spindle 22 of the roller shuttle 10 preferably receives rollers as follows: from the inside to the outside, the number of turns increases or the diameter increases.

[0061] For example Figure 5 As shown, the roller shuttle 10 may be appropriately equipped with a switch box containing circuit electronics for operating and controlling the drive and servo motor used in the operation of the loading spindle 22.

[0062] Figure 6 This is a schematic diagram of a frame system in which the roller shuttle 10 according to the invention is used in combination with the suspended roller shuttle according to the invention.

[0063] and Figure 4 similar, Figure 6 The roller shuttle 10, fixed storage box 36, and movable storage box 38 according to the present invention are shown. For a description of these units, refer to the above description. Figure 4 Related comments.

[0064] like Figure 6 As further shown, within the scope of the invention, a suspended roller shuttle can be used. Therefore, according to the invention, a support rail 40 is provided laterally relative to the travel direction of the roller shuttle 10. This support rail not only covers the travel area of ​​the roller shuttle, but also the storage area of ​​the storage box (preferably, the movable storage box 38), and the loading area for transporting the rollers and removing them from the storage area.

[0065] like Figure 6 As shown, the material flow proceeds in the following direction: from the loading area, along guide rail 40, for example laterally relative to the direction of travel, towards, for example, the movable storage box 38. Once the rollers are properly stored in the movable storage box 38, they can be moved parallel to the travel guide rail of the roller shuttle 10. Subsequently, the roller shuttle 10 can be positioned relative to the movable storage box 38 to subsequently receive rollers to be stored or remove rollers from the storage area (from the movable storage box 38) and move them in a suitable manner to the fixed storage box 36. In the case of removal from the storage area, the material flow proceeds in the opposite direction, i.e., via the roller shuttle 10 from the fixed storage box 36 to the movable storage box 38, through which it can then be moved from the storage area along the suspension guide rail 40 to the loading area.

[0066] Figure 7 This is a schematic diagram illustrating the operating mode of the suspended roller shuttle according to the present invention.

[0067] like Figure 7As shown, according to the present invention, a suspended roller shuttle 42 is provided for conveying rollers to a transfer station for further conveying in a racking system. The suspended roller shuttle 42 includes a suspension frame 44 on which wheels 46-1, 46-2 are mounted to allow the suspended roller shuttle to move along a suspension guide rail 40 mounted on the upper side of the storage plane of the racking system.

[0068] Then, the loading mandrel 48 is fixed to the suspension frame 44, through which the mandrel roller to be stored can move along the travel direction of the suspension guide 40. Preferably, the loading mandrel 48 of the suspension frame 44 is equipped with a chain conveyor to position the roller to be stored along the loading mandrel, i.e., to receive or lower the roller. Preferably, the length of the loading mandrel 48 is an integer multiple of the width of the roller to be conveyed.

[0069] like Figure 7 As shown, a pivotable stop 50 can be provided on the suspension frame 44, which is used to fix the rollers during the conveying of the suspension guide 40.

[0070] like Figure 7 As shown, once the suspended roller shuttle 42 is positioned, for example, above the mobile storage box 38, roller exchange can be performed between the suspended roller shuttle 42 and the mobile storage box 38. For this purpose, the mobile storage box 38 may preferably be provided with a lifting device 52 to transport rollers from the suspended roller shuttle 42 to the mobile storage box 38, or to transfer rollers from the mobile storage box 38 to the loading mandrel 48 of the suspended roller shuttle 42, after raising the storage surface of the mobile storage box 38.

[0071] Figure 8 This is a perspective view of a suspended roller shuttle 42 according to the present invention, which includes multiple rollers of different diameters mounted on a spindle system.

[0072] like Figure 8 As shown, similar to the case of roller shuttle 10, in the case of suspended roller shuttle 42, the loading mandrel is preferably assembled such that the diameter of the multiple rollers increases from the inside out. A stop 50 secures the rollers to prevent them from slipping off the loading mandrel during transport.

[0073] like Figure 8 As shown, the suspended roller shuttle 42 may further include a unit 54, which is provided with a switching device and electronics suitable for operating the suspended roller shuttle 42.

[0074] Figure 9 This is a perspective view of the storage system according to the present invention.

[0075] like Figure 9 As shown, the rack system for storing and conveying rollers according to the invention includes multiple storage planes. Multiple travel rails for conveying the rollers extend in each storage plane. Multiple storage bins are adjacent to corresponding travel rails in each storage plane. According to the invention, the roller shuttle 10 according to the invention can now move along the travel rails for conveying the rollers.

[0076] Preferably, within the scope of the invention, at least one roller shuttle 10 is used in combination with at least one suspended roller shuttle 42, as shown in the reference. Figure 6 As described above. In this case, roller shuttles are used for conveying within the shelving system, while suspended roller shuttles are used for further conveying between shelving systems or between different functional areas within a shelving system. Furthermore, suspended roller shuttles can be used to distribute rollers and other stored goods to widely distributed delivery and receiving stations, and / or to place the rollers from those stations into storage areas.

[0077] like Figure 9 As shown, one or more lifting systems 56 may preferably be provided on the end face of the shelving system. These lifting systems also allow the roller shuttle 10 according to the invention to move vertically across multiple storage planes of the shelving system. Preferably, each lifting system 56 serves one loading area of ​​the shelving system, and the number of roller shuttle sub-10s or suspended roller shuttles 42 used in each storage plane can be freely configured according to usage.

[0078] like Figure 9 As shown, the shelving system according to the invention also includes an inspection platform 58 to allow access to the suspended roller shuttle for maintenance or repair activities. Figure 9 As further shown, the travel rails for the suspended roller shuttle can be guided into the housing 60. This allows for, for example, improved protection against weather or protection of the goods to be transported from external influences.

[0079] Figure 10 An example for accessing the suspended roller shuttle is shown. This illustrates that the inspection platform can also be housed within the housing 60, which improves protection for maintenance personnel. Preferably, the inspection platform is arranged in height to allow maintenance personnel comfortable access to the suspended roller shuttle. This is a preferred embodiment to allow operation of the scaffold components, but also allows handling of the rollers within the scaffold system.

[0080] Figure 11 This illustrates a suspended roller shuttle system used as a conveyor system between various functional units within a frame system. For example... Figure 11As shown, or as an example, the functional units may be provided by delivery receiving stations 62, 64, 66, etc. Figure 9 The shelving system shown comprises the shelving system itself and a temporary storage area 68. According to... Figure 11 The temporary storage area can be equipped with pre-partitioned areas, thus serving as a buffer for inserting and removing goods and rollers from the storage areas of the shelving system. Furthermore, the pre-partitioned areas can store goods, or goods can be transported from the pre-partitioned areas to the corresponding transfer stations 66 via the overhead conveyor system 70. Typically, the overhead conveyor system according to the invention is also suitable for interconnecting the entire shelving system.

[0081] Figure 12 Further construction of some components of the shelving system according to the invention is illustrated by way of example. Figure 12 As shown, the suspended roller shuttle 42 can also be mounted at various heights. For this purpose, a vertical lift is used, which includes a receiving device 72 positioned appropriately close to the distribution station 74. After receiving the roller goods, the vertical lift travels to one or more transfer stations 76, 78, through which the suspended roller shuttle 42 can pass. At the transfer stations 76, 78, the suspended roller shuttle 42 then receives the roller goods for movement within the shelving system. The advantage of providing a maintenance or inspection platform 58 here is that it allows maintenance personnel to access the platform using a ladder 80.

[0082] In summary, this invention allows for the combined use of highly efficient roller shuttles or suspended roller shuttles with scaffolding systems to achieve roller storage at one or more depths. Roller handling is specifically ensured using a loading mandrel system. Regarding the conveying of rollers within the scaffolding system, the rollers can also preferably move on a suspended roller shuttle.
