Description

Technical Field

[0001] This invention relates to the field of transport racking technology, and in particular to a multi-layer transport racking for parts boxes. Background Technology

[0002] In the vehicle manufacturing process, parts boxes are typically used to hold vehicle components. These boxes are then transferred to the vehicle assembly line so that workers can retrieve the components from them. To improve the efficiency of this transfer, transport racks are usually used to move the parts boxes to pallets located next to the assembly line. Workers then retrieve the components from the boxes placed on the pallets. However, vehicles have a wide variety of components. When a part box containing one type of component occupies the pallet, the transport racks cannot transfer a part box containing another type of component to the pallet, resulting in low transport efficiency. Therefore, it is necessary to add multiple transport racks to transport multiple parts boxes simultaneously to improve efficiency. However, existing transport racks are large and occupy a large area, and setting up multiple transport racks further reduces the space utilization rate of the workshop. Summary of the Invention

[0033] This invention proposes a multi-layer transport rack for parts boxes.

[0034] This embodiment provides a multi-layer transport rack 100 for component boxes. The multi-layer transport rack 100 includes a support mechanism 10 and a conveying mechanism 20. The support mechanism 10 includes a base frame 11 and multiple support platforms 12 for supporting component boxes. The multiple support platforms 12 are arranged sequentially on the base frame 11 along a first direction and are vertically spaced. Each support platform 12 has a loading area 121 and a unloading area 122 arranged side by side along a second direction. Both the first and second directions are transverse and perpendicular to each other. The number of conveying mechanisms 20 is the same as the number of support platforms 12 and they are arranged in a one-to-one correspondence. The conveying mechanism 20 includes a first drive assembly 21 and two conveyor frames 22 for conveying component boxes. The two conveyor frames 22 are arranged side by side along a second direction and both extend along a first direction. One conveyor frame 22 is connected to the loading area 121 and is inclined upward from the loading area 121 in a direction away from the support platform 12. The other conveyor frame 22 is connected to the unloading area 122 and is inclined downward from the unloading area 122 in a direction away from the support platform 12. The first drive assembly 21 is mounted on the base frame 11 and is used to drive the component boxes supported on the support platform 12 to move from the loading area 121 to the unloading area 122.

[0035] like Figure 1 and Figure 2 As shown, multiple support platforms 12 are installed on the base frame 11. The multiple support platforms 12 are arranged at intervals in the vertical direction and sequentially arranged in the first direction, which is the left-right direction. That is, the multiple support platforms 12 are distributed in a stepped manner on the base frame 11. The support platforms 12 are used to support the component boxes, and the support platforms 12 have a loading area 121 and a unloading area 122 for placing the component boxes. The loading area 121 and the unloading area 122 are arranged side by side in the second direction, which is the front-back direction. Two parallel conveyor frames 22 are connected to the support platform 12. The two conveyor frames 22 are respectively set to the loading area 121 and the unloading area 122. The conveyor frame 22 set to the loading area 121 is inclined upward from the support platform 12, and the conveyor frame 22 set to the unloading area 122 is inclined downward from the support platform 12. It should be noted that the multi-layer transport rack 100 of the present invention can be used to transport and place various materials. In this embodiment, only the transport of parts boxes by the multi-layer transport rack 100 is used as an example for illustration. The parts boxes are used to hold parts.

[0036] When transporting parts boxes containing components, the parts boxes are first placed on the conveyor frame 22 set in the corresponding loading area 121. The parts boxes slide down from top to bottom along the extension direction of the conveyor frame 22 to the loading area 121 on the support platform 12. The support platform 12 serves to stably support the parts boxes so that the parts boxes containing components are placed in the loading area 121, making it convenient for operators to take the components from the parts boxes. Understandably, after the components in the parts boxes are used up, the first drive assembly 21 drives the parts boxes to move from the loading area 121 to the unloading area 122 along the support platform 12. The operators push the parts boxes from the unloading area 122 onto the conveyor frame 22 set in the corresponding unloading area 122 so that the parts boxes slide down from top to bottom along the extension direction of the conveyor frame 22 to the end away from the support platform 12, making it convenient for operators to retrieve the empty parts boxes.

[0037] The multi-layer transport rack 100 of this embodiment includes multiple support platforms 12. Each support platform 12 is connected to a conveyor frame 22 that communicates with the loading area 121 and a conveyor frame 22 that communicates with the unloading area 122. The conveyor frame 22 that communicates with the loading area 121 is used to transport the component boxes to the support platform 12. The first drive component 21 is used to move the component boxes from the loading area 121 of the support platform 12 to the unloading area 122. The conveyor frame 22 that communicates with the unloading area 122 is used to transport the component boxes to a position away from the support platform 12. The multiple support platforms 12 and the conveyor frames 22 connected to the support platforms 12 can realize the synchronous transport of multiple component boxes without unloading the component boxes from the support platforms 12. This not only makes it easier for operators to pick up parts, but also improves the transport efficiency of component boxes. In addition, the multiple support platforms 12 are arranged vertically at intervals, which makes the multi-layer transport rack 100 occupy a small area and improves the space utilization rate.

[0038] In this embodiment, the first driving component 21 includes a first driving member 211 and a vertically arranged push rod 212. The support platform 12 has a slide groove 123 extending in a second direction corresponding to the loading area 121. The first driving member 211 is located below the support platform 12. The lower end of the push rod 212 is connected to the first driving member 211. The push rod 212 passes through the slide groove 123 and the upper end of the push rod 212 is located above the support platform 12. The first driving member 211 is used to drive the push rod 212 to slide relative to the support platform 12 along the extension direction of the slide groove 123, so that the push rod 212 pushes the component box from the loading area 121 to the unloading area 122.

[0039] like Figures 3 to 6 As shown, the loading area 121 of the support platform 12 has a chute 123 extending towards the loading area 122. The first drive member 211 is installed below the support platform 12, and a push rod 212 is connected to the first drive member 211 at the position corresponding to the chute 123. The push rod 212 extends upward and passes through the chute 123. The first drive member 211 can drive the push rod 212 to slide back and forth in the chute 123 along the extension direction of the chute 123. When it is necessary to transport the part box from the loading area 121 to the unloading area 122, the first drive member 211 drives the push rod 212, which abuts against one side of the part box, to slide towards the loading area 122, so that the push rod 212 pushes the part box to the unloading area 122. It can be understood that the first drive member 211 drives the push rod 212 to slide in the opposite direction away from the unloading area 122, so that the push rod 212 is reset. There is no need for manual handling of the part box, which further improves the transportation efficiency of the part box.

[0040] Furthermore, there are multiple slide grooves 123, which are spaced apart along the first direction. A connecting plate 213 is provided on the first driving member 211, and multiple push rods 212 spaced apart along the first direction are connected to the connecting plate 213. The number of push rods 212 is the same as the number of slide grooves 123, and they slide in a one-to-one correspondence. Figures 3 to 6 As shown, a connecting plate 213 is connected to the first driving component 211, and multiple push rods 212 are connected to the connecting plate 213. Slide grooves 123 are provided on the support platform 12 corresponding to the positions of each push rod 212. The multiple push rods 212 can push the part box synchronously, ensuring the stable delivery of the part box. Furthermore, the first driving component 211 can be a rodless cylinder in the prior art. The connecting plate 213 is connected to the slider of the rodless cylinder. The slider drives the connecting plate 213 and the multiple push rods 212 on the connecting plate 213 to move synchronously along the guide rail of the rodless cylinder.

[0041] In this embodiment, the conveyor frame 22 includes multiple conveyor rods 221, which are spaced apart along a second direction, and each conveyor rod 221 extends along a first direction and is connected to the support platform 12. Each conveyor rod 221 has a mounting groove 222, the extension direction of which is consistent with the extension direction of the conveyor rod 221. Multiple rollers 223 are disposed within the mounting groove 222, spaced apart along the extension direction of the mounting groove 222. Each roller 223 is rotatably connected to the side wall of the mounting groove 222, and the outer edge of each roller 223 protrudes from the opening of the mounting groove 222.

[0042] like Figures 3 to 6 As shown, each conveyor frame 22 includes multiple spaced conveyor rods 221. The conveyor rods 221 corresponding to the loading area 121 are inclined upwards from the loading area 121 in a direction away from the loading area 121, allowing the part boxes to slide onto the support platform 12 along the conveyor rods 221 corresponding to the loading area 121. The conveyor rods 221 corresponding to the unloading area 122 are inclined downwards from the unloading area 122 in a direction away from the unloading area 122, allowing the part boxes to slide to a position away from the support platform 12 along the conveyor rods 221 corresponding to the unloading area 122, facilitating the retrieval of empty part boxes by operators. Furthermore, each conveyor rod 221 is equipped with multiple rollers 223, all of which can rotate relative to the part box. This not only assists in transporting the part boxes and improves transport efficiency but also reduces the friction between the part boxes and the conveyor rods 221, thus protecting the part boxes.

[0043] In one embodiment, such as Figures 3 to 6As shown, the conveying mechanism 20 also includes a second drive assembly (not shown) and a plurality of rollers 23, which are spaced apart in the feeding area 121 along a first direction and each roller 23 extends along a second direction. The second drive assembly is used to drive the plurality of rollers 23 to rotate synchronously. The conveying mechanism 20 also includes a plurality of balls 24, which are spaced apart in the unloading area 122. When transporting component boxes onto the support platform 12, the component boxes slide along the conveyor frame 22 corresponding to the loading area 121 towards the support platform 12. The second drive unit drives multiple rollers 23 on the loading area 121 to rotate synchronously relative to the component boxes, so that the multiple rollers 23 roll into contact with the component boxes, thereby assisting in transporting the component boxes from the conveyor frame 22 to the support platform 12, ensuring that the component boxes are transported to the correct position, and further improving the component box transport efficiency. In addition, the unloading area 122 is equipped with multiple ball bearings 24, which are arranged in an array on the support platform 12 and can roll relative to the component boxes, facilitating the transport of the component boxes from the loading area 121 to the unloading area 122 and making it easier for operators to push the component boxes onto the conveyor frame 22, further assisting in the transport of the component boxes.

[0044] Furthermore, the second drive assembly includes a second drive member, a synchronous belt, a drive pulley, and multiple driven pulleys. The number of driven pulleys is the same as the number of rollers 23, and each driven pulley is fitted onto the end of its corresponding roller 23 away from the unloading area 122. The synchronous belt is wrapped around the outer periphery of the drive pulley and the multiple driven pulleys. The second drive member is used to drive the drive pulley to rotate, so that the drive pulley drives the multiple rollers 23 to rotate synchronously via the synchronous belt and the multiple driven pulleys. Each roller 23 has a driven pulley fitted onto the end away from the unloading area 122. The multiple driven pulleys are connected to the drive pulley via the synchronous belt. The second drive member can be a motor as in the prior art. The drive pulley is fitted onto the output shaft of the motor. The motor drives the drive pulley to rotate, so that the drive pulley drives the multiple driven pulleys to rotate synchronously via the synchronous belt. Each driven pulley drives the roller 23 corresponding to it to rotate, thereby realizing the synchronous rotation of the multiple rollers 23. The synchronous rotation of the multiple rollers 23 assists in transporting the part box to the support platform 12.

[0045] In another embodiment, multiple balls 24 can be provided on both the loading area 121 and the unloading area 122. The multiple balls 24 are arrayed on the support platform 12, and each ball 24 can roll relative to the part box, facilitating the transportation of the part box. In yet another embodiment, multiple rollers 23 can be provided on the support platform 12, spaced apart along a first direction. The rollers 23 extend from one end of the support platform 12 to the other end, that is, from the loading area 121 to the unloading area 122. When transporting part boxes onto the support platform 12, the multiple rollers 23 rotate synchronously to assist in transporting the part boxes to their designated positions. When transporting part boxes from the support platform 12 to the conveyor frame 22, the multiple rollers 23 rotate synchronously in opposite directions, eliminating the need for operators to push the part boxes, further improving transportation efficiency.

[0046] The multi-layer transport rack 100 in this embodiment also includes a stop mechanism 30. The stop mechanism 30 includes a third drive member 31 and a stop block 32 connected to the third drive member 31. The third drive member 31 is installed on the base frame 11 on the side near the conveyor frame 22, and the third drive member 31 is set corresponding to the loading area 121. The third drive member 31 is used to drive the stop block 32 to rise and fall relative to the support platform 12, so that the stop block 32 rises above the support platform 12 or falls below the support platform 12.

[0047] like Figure 5 and Figure 6 As shown, each support platform 12 is equipped with at least one stop mechanism 30 at the position corresponding to the loading area 121. The third drive component 31 of the stop mechanism 30 can be a lifting cylinder in the prior art. The cylinder body is connected to the base frame 11, and the output shaft of the cylinder extends upward and is connected to the stop block 32. The output shaft of the cylinder can drive the stop block 32 to rise and fall relative to the base frame 11. When a part box is placed on the support platform 12, the third drive component 31 drives the stop block 32 to rise above the support platform 12, which prevents other part boxes from sliding from the conveyor frame 22 onto the support platform 12. The structure is stable and reliable. When it is necessary to transport a part box containing parts to the support platform 12, the third drive component 31 drives the stop block 32 to fall below the support platform 12, so that the part box can slide along the conveyor frame 22 onto the support platform 12.

[0048] In a preferred embodiment, the support platform 12 is equipped with position sensors 40 for detecting the component boxes, corresponding to both the loading area 121 and the unloading area 122. Figure 5 and Figure 6As shown, two position sensors 40 are installed on the support platform 12. The two position sensors 40 are respectively located in the loading area 121 and the unloading area 122. Both position sensors 40 can be used to detect the position of the parts box. When the position sensor 40 located in the loading area 121 detects that there is no parts box in the loading area 121, the third driving component 31 drives the stop block 32 to descend below the support platform 12, so that the parts box can be transported onto the support platform 12. It can be understood that when the position sensor 40 located in the loading area 121 detects loading... When there is a component box in zone 121, the third drive component 31 drives the stop block 32 to rise above the support platform 12 to prevent other component boxes from slipping, ensuring structural stability and reliability. When the position sensor 40 in the unloading zone 122 detects that there is no component box in the unloading zone 122, the first drive component 211 drives the push rod 212 to push the empty component box into the unloading zone 122. Understandably, when the position sensor 40 in the unloading zone 122 detects that there is a component box in the unloading zone 122, the first drive component 211 drives the push rod 212 to reset. In addition, the multi-layer transport rack 100 also includes a controller, which controls the start and stop of the first drive component 211, the second drive component, and the third drive component 31 based on the detection information from the two position sensors 40. The controller can be a PLC controller as described in the prior art.

[0049] In this embodiment, the base frame 11 includes vertical bars 111 and horizontal bars 112. There are multiple vertical bars 111 arranged in an array, and any two adjacent vertical bars 111 are connected by a horizontal bar 112. Reinforcing components are provided on the base frame 11 at positions corresponding to each conveyor frame 22. Each reinforcing component includes multiple reinforcing rods 113, which are spaced apart along the extension direction of their corresponding conveyor frame 22. Each reinforcing rod 113 extends along a second direction and connects between two adjacent vertical bars 111. Figure 1 and Figure 2 As shown, the base frame 11 is used to install on the ground to fix and install multiple support platforms 12. Multiple vertical bars 111 and multiple horizontal bars 112 cooperate with each other to support multiple support platforms 12. Each conveyor frame 22 is provided with a reinforcing component at its lower end. Each reinforcing component includes multiple reinforcing bars 113 arranged at intervals. The conveyor frame 22 is supported on multiple reinforcing bars 113 that are correspondingly arranged, which further improves the stability of the structure.

[0050] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
