Description

Technical Field

[0001] This utility model relates to the field of shelving technology, and in particular to a shelving and material transport device. Background Technology

[0002] In the automobile production process, multiple parts need to be assembled, and each part needs to be transported from its respective production line or storage location to the assembly line for assembly.

[0003] In existing technology, workers transport empty boxes onto trolleys to shelves containing components. They then need to dismount the trolley, lower the bridge to connect it to the shelf, push the empty boxes onto the shelf, walk to the shelf with full boxes, push the full boxes into the transport trolley, and finally retract the bridge. The workers then return to the trolley and drive it to the assembly line. During this process, workers must get on and off the trolley to complete the exchange, making the entire transportation process cumbersome and time-consuming. Furthermore, the workers operate in confined spaces, increasing the risk of injuries such as pinching and collisions.

[0004] Therefore, it is necessary to provide a new type of shelving and material handling device to solve the above-mentioned technical problems. Utility Model Content

[0005] The main purpose of this utility model is to propose a shelf and material transportation device, which aims to improve the technical problems of the cumbersome and time-consuming process of transporting components in the prior art, and the easy injury of operators.

[0006] To achieve the above objectives, according to one aspect of the present invention, a shelf is provided, comprising:

[0007] The transport platform includes two empty box areas and a material area spaced apart along the length of the shelf;

[0008] A drive assembly, the drive assembly being mounted on the transport platform;

[0009] A photoelectric switch is installed on the transport platform and is used to detect the positional relationship between the shelf and the transport trolley.

[0010] The controller, the photoelectric switch and the drive component are both signal connected to the controller;

[0011] The first telescopic frame is slidably installed on the transport platform and is located below the empty box area. The extension shaft of the drive assembly is connected to the first telescopic frame to drive the first telescopic frame to extend along the width direction of the shelf to abut against the transport trolley.

[0012] The second telescopic frame is slidably mounted on the transport platform and is located below the material area. The extension shaft of the drive assembly is connected to the second telescopic frame to drive the second telescopic frame to extend along the width direction of the shelf until it abuts against the transport trolley.

[0013] In one embodiment, both the empty container area and the material area are inclined, with the height of the empty container area near the transport trolley being higher than the height of the empty container area away from the transport trolley, and the height of the material area near the transport trolley being lower than the height of the material area away from the transport trolley.

[0014] In one embodiment, both the first telescopic frame and the second telescopic frame are inclined, with the first telescopic frame inclined in the same direction as the empty box area, and the second telescopic frame inclined in the same direction as the material area.

[0015] In one embodiment, the empty box area includes a plurality of first tracks spaced apart along the length of the shelf, each first track being provided with a plurality of first rollers spaced apart along the width of the shelf, the first rollers being used to roll into contact with the empty boxes; the material area includes a plurality of second tracks spaced apart along the length of the shelf, each second track being provided with a plurality of second rollers spaced apart along the width of the shelf, the second rollers being used to roll into contact with boxes containing materials.

[0016] In one embodiment, the bottom of the second telescopic frame is provided with a plurality of traveling wheels, which are arranged in a square shape and are all used for rolling contact with the ground.

[0017] In one embodiment, the drive assembly includes two telescopic cylinders, both of which are connected to the photoelectric switch signal. The cylinder bodies of both telescopic cylinders are mounted on the transport platform. The extension shaft of one telescopic cylinder is connected to the first telescopic frame, and the extension shaft of the other telescopic cylinder is connected to the second telescopic frame.

[0018] In one embodiment, the shelf further includes a first blocking component, which includes a blocking cylinder and a first blocking rod. The cylinder body of the blocking cylinder is mounted on the transport platform, and the extension shaft of the blocking cylinder is connected to the first blocking rod. The blocking cylinder drives the first blocking rod to rise or fall vertically to block or allow the passage of boxes containing materials. The blocking cylinder is also signal-connected to the controller.

[0019] According to another aspect of the present invention, the present invention also provides a material transport device, including a transport trolley and the aforementioned shelf. The transport trolley includes a first platform and a second platform. The first platform is used to place empty boxes, and the second platform is used to place boxes containing materials. The first platform is used to abut against the first telescopic frame, and the second platform is used to abut against the second telescopic frame.

[0020] In one embodiment, the transport trolley further includes a second blocking component disposed on the first platform, and the shelf further includes an adjusting rod disposed on the first telescopic frame. The adjusting rod is capable of abutting against the second blocking component to allow the second blocking component to release the empty box.

[0021] In one embodiment, the second blocking component includes a touch rod, a pulley system, an elastic line, and a second blocking rod. The touch rod is telescopically mounted on the first platform, and the second blocking rod is telescopically mounted on the first platform in a vertical direction. One end of the elastic line is connected to the touch rod, and the other end of the elastic line is connected to the bottom of the second blocking rod. The elastic line is also slidably connected to the pulley system. When the adjusting rod abuts against the touch rod, it pushes the touch rod to move away from the shelf and pulls the second blocking rod downward through the elastic line to allow the empty box to pass.

[0022] In the above scheme, the rack includes a transport platform, a drive assembly, a photoelectric switch, a controller, a first telescopic frame, and a second telescopic frame. The transport platform includes two empty box areas and a material area spaced apart along the length of the rack. The drive assembly is installed on the transport platform, and the photoelectric switch is located on the transport platform. The photoelectric switch is used to detect the positional relationship between the rack and the transport trolley. Both the photoelectric switch and the drive assembly are connected to the controller signal. The first telescopic frame is slidably installed on the transport platform and is located below the empty box area. The extension shaft of the drive assembly is connected to the first telescopic frame to drive the first telescopic frame to extend along the width of the rack until it abuts against the transport trolley. The second telescopic frame is slidably installed on the transport platform and is located below the material area. The extension shaft of the drive assembly is connected to the second telescopic frame to drive the second telescopic frame to extend along the width of the rack until it abuts against the transport trolley. Specifically, operators drive a transport trolley along a fixed route. Photoelectric switches on the shelving continuously monitor the positional relationship between the trolley and the shelving, transmitting the signal to the controller. When the photoelectric switches detect that the positional relationship matches the preset position in the controller, it indicates that the trolley has reached its designated position. At this point, the controller activates the extension shaft of the drive assembly, causing the first telescopic frame to contact the first platform of the transport trolley, and the second telescopic frame to contact the second platform. This allows operators to push empty boxes from the first platform onto the first telescopic frame, and then continue pushing empty boxes into the empty box area, thus arranging the shelving. The boxes containing materials are pushed from the material area to the second telescopic frame, and then further pushed to the second platform of the transport trolley. This completes the exchange between empty and filled boxes. The operator then continues to drive the transport trolley along the track to the assembly area to remove the materials for assembly. In this invention, the photoelectric switch, drive assembly, and controller work together to achieve automatic connection and disconnection between the transport trolley and the shelf, realizing the exchange between empty and filled boxes. This simplifies the material transportation process, improves transportation efficiency, and eliminates the need for operators to walk to the filled box shelf to push the filled boxes into the transport trolley, thus preventing operator injury.

[0035] To achieve the above objectives, according to one aspect of this utility model, please refer to... Figure 1 and Figure 2This utility model proposes a shelf 100, including a transport platform 1, a drive assembly 2, a photoelectric switch 3, a controller 4, a first telescopic frame 5, and a second telescopic frame 6. The transport platform 1 includes two empty box areas 11 and a material area 12 spaced apart along the length of the shelf 100. The drive assembly 2 is installed on the transport platform 1. The photoelectric switch 3 is installed on the transport platform 1 and is used to detect the positional relationship between the shelf 100 and the transport trolley 101. Both the photoelectric switch 3 and the drive assembly 2 are signal-connected to the controller 4. The first telescopic frame 5 is slidably installed on the transport platform 1 and is located below the empty box area 11. The extension shaft of the drive assembly 2 is connected to the first telescopic frame 5 to drive the first telescopic frame 5 to extend along the width of the shelf 100 to abut against the transport trolley 101. The second telescopic frame 6 is slidably installed on the transport platform 1 and is located below the material area 12. The extension shaft of the drive assembly 2 is connected to the second telescopic frame 6 to drive the second telescopic frame 6 to extend along the width of the shelf 100 to abut against the transport trolley 101.Specifically, the operator drives the transport trolley 101 along a fixed route. The photoelectric switch 3 on the shelf 100 detects the positional relationship between the transport trolley 101 and the shelf 100 in real time and transmits the positional relationship signal to the controller 4 in real time. When the photoelectric switch 3 detects that the positional relationship between the transport trolley 101 and the shelf 100 matches the preset positional relationship in the controller 4, it indicates that the transport trolley 101 has reached its position. At this time, the controller 4 controls the extension shaft of the drive assembly 2 to extend, so that the first telescopic frame 5 abuts against the first platform 101a of the transport trolley 101, and the second telescopic frame 6 abuts against the second platform 101b of the transport trolley 101. In this way, the operator can push the empty boxes on the first platform 101a of the transport platform 1 onto the first telescopic frame 5, and then continue to push the empty boxes into the empty box area 11. The operator can then push the boxes containing materials on the material area 12 of the shelf 100 onto the second telescopic frame 6, and then continue to push the boxes containing materials onto the transport trolley 101. On the second platform 101b, the exchange between empty boxes and boxes filled with materials is completed. Then, the operator continues to drive the transport trolley 101 along the track to the assembly area, removes the materials, and assembles them. After the transport trolley 101 moves away from the shelf 100, when the photoelectric switch 3 detects that the positional relationship between the transport trolley 101 and the shelf 100 does not conform to the preset positional relationship in the controller 4, the controller 4 controls the extension shaft of the drive component 2 to retract. In this way, the first telescopic frame 5 will retract to below the empty box area 11, and the second telescopic frame 6 will retract to below the material area 12. In this embodiment, the photoelectric switch 3, the drive component 2, and the controller 4 cooperate to realize the automatic connection and disconnection of the transport trolley 101 and the shelf 100, realizing the exchange between empty boxes and full boxes. This simplifies the material transportation steps, improves transportation efficiency, and eliminates the need for operators to walk to the full box shelf 100 to push the full boxes into the transport trolley, thus preventing operator injuries.

[0036] Please see Figure 1 and Figure 2In one embodiment, both the empty box area 11 and the material area 12 are inclined. The height of the end of the empty box area 11 near the transport trolley 101 is higher than the height of the end of the empty box area 11 away from the transport trolley 101, and the height of the end of the material area 12 near the transport trolley 101 is lower than the height of the end of the material area 12 away from the transport trolley 101. Operators drive the transport trolley 101 along a fixed route. The photoelectric switch 3 on the shelf 100 detects the positional relationship between the transport trolley 101 and the shelf 100 in real time and transmits the positional relationship signal to the controller 4 in real time. When the photoelectric switch 3 detects that the positional relationship between the transport trolley 101 and the shelf 100 matches the preset positional relationship in the controller 4, it indicates that the transport trolley 101 has reached its position. At this time, the controller 4 controls the extension shaft of the drive assembly 2 to extend, so that the first telescopic frame 5 abuts against the first platform 101a of the transport trolley 101, and the second telescopic frame 6 abuts against the second platform 101b of the transport trolley 101. Since the empty box area 11 and the material area 12 are inclined and the inclination directions are opposite... Conversely, the operator pushes the empty box on the first platform 101a of the transport platform 1 onto the first telescopic frame 5, and then continues to push the empty box into the empty box area 11. The empty box will continue to slide due to its own weight until it comes into contact with the previous empty box or the side of the shelf 100. At the same time, the material area 12 is tilted, and the boxes containing materials in the material area 12 will slide due to their own weight onto the second telescopic frame 6, and then continue to slide onto the second platform 101b of the transport trolley 101. This completes the exchange between the empty box and the box containing materials. By tilting the empty box area 11 and the material area 12, the operator does not need to push the empty box or the box containing materials throughout the entire process, thereby reducing the labor intensity of the operator.

[0037] Please see Figure 1 and Figure 2In one embodiment, both the first telescopic frame 5 and the second telescopic frame 6 are inclined. The inclination direction of the first telescopic frame 5 is the same as the inclination direction of the empty box area 11, and the inclination direction of the second telescopic frame 6 is the same as the inclination direction of the material area 12. The operator drives the transport trolley 101 along a fixed route. The photoelectric switch 3 on the shelf 100 detects the positional relationship between the transport trolley 101 and the shelf 100 in real time and transmits the positional relationship signal to the controller 4 in real time. When the photoelectric switch 3 detects that the positional relationship between the transport trolley 101 and the shelf 100 matches the preset positional relationship in the controller 4, it indicates that the transport trolley 101 has reached its position. At this time, the controller 4 controls the extension shaft of the drive assembly 2 to extend, so that the first telescopic frame 5 abuts against the first platform 101a of the transport trolley 101, and the second telescopic frame 6 abuts against the second platform 101b of the transport trolley 101. The operator then moves the first platform 101a of the transport platform 1... The empty boxes are pushed onto the first telescopic frame 5. Since the first telescopic frame 5 and the empty box area 11 are both tilted in the same direction, the empty boxes will slide under their own weight until the empty box area 11 comes into contact with the previous empty box or with the side of the shelf 100. At the same time, the material area 12 and the second telescopic frame 6 are tilted in the same direction. The boxes in the material area 12 containing materials will slide onto the second telescopic frame 6 under their own weight and continue to slide onto the second platform 101b of the transport trolley 101. This completes the exchange between the empty boxes and the boxes containing materials. By further tilting the first telescopic frame 5 and the second telescopic frame 6, the labor intensity of the operators can be further reduced.

[0038] Please see Figure 1 and Figure 2In one embodiment, the empty box area 11 includes a plurality of first tracks 111 spaced apart along the length of the shelf 100. Each first track 111 is provided with a plurality of first rollers 111a spaced apart along the width of the shelf 100. The first rollers 111a are used for rolling contact with empty boxes. The material area 12 includes a plurality of second tracks 121 spaced apart along the length of the shelf 100. Each second track 121 is provided with a plurality of second rollers 121a spaced apart along the width of the shelf 100. The second rollers 121a are used for rolling contact with boxes containing materials. Rolling contact significantly reduces friction compared to sliding contact, which makes the movement of empty boxes or boxes containing materials smoother in the empty box area 11 or the material area 12, preventing empty boxes or boxes containing materials from getting stuck in the empty box area 11 or the material area 12. The roller design allows empty or loaded containers to move faster and more efficiently along the tracks, especially when tilted. Gravity-assisted rolling is smoother than direct sliding, improving overall material handling efficiency. Multiple tracks and rollers provide more support points for empty or loaded containers, allowing for better load distribution and ensuring stability during movement, reducing the risk of tipping due to imbalance. Because the tracks and rollers are spaced at specific intervals, pallet size and weight limits can be adjusted as needed, increasing system flexibility and adaptability to different pallet sizes.

[0039] Please see Figure 1 and Figure 2 In one embodiment, the bottom of the second telescopic frame 6 is provided with multiple traveling wheels 61. The multiple traveling wheels 61 are arranged in a square shape and are all used for rolling contact with the ground. Since the box containing materials is relatively heavy, the traveling wheels 61 are provided at the bottom of the second telescopic frame 6 so that when the second telescopic frame 6 extends, it can support the heavy box containing materials and prevent it from being crushed.

[0040] Please see Figure 1 and Figure 2 In one embodiment, the drive assembly 2 includes two telescopic cylinders 21, both of which are signal-connected to a photoelectric switch 3. The cylinder bodies of both cylinders 21 are mounted on the transport platform 1. The extension shaft of one cylinder 21 is connected to a first telescopic frame 5, and the extension shaft of the other cylinder 21 is connected to a second telescopic frame 6. By connecting the two telescopic cylinders 21 to the first telescopic frame 5 and the second telescopic frame 6 respectively, independent control of the empty box area 11 and the material area 12 can be achieved. This allows for individual operation of either telescopic frame according to actual needs, improving operational flexibility and accuracy. Simultaneously, the two cylinders 21 can also work simultaneously, extending or retracting at the same time, to speed up the entire loading and unloading process and improve work efficiency.

[0041] Please see Figure 1 and Figure 2 In one embodiment, the shelf 100 further includes a first blocking component 7, which includes a blocking cylinder 71 and a first blocking rod 72. The cylinder body of the blocking cylinder 71 is mounted on the transport platform 1, and the extension shaft of the blocking cylinder 71 is connected to the first blocking rod 72. The blocking cylinder 71 drives the first blocking rod 72 to rise or fall in the vertical direction to block or allow the box containing the material to pass. The blocking cylinder 71 is also signal-connected to the controller 4. The operator drives the transport trolley 101 along a fixed route. The photoelectric switch 3 on the shelf 100 detects the positional relationship between the transport trolley 101 and the shelf 100 in real time and transmits the positional relationship signal to the controller 4 in real time. When the photoelectric switch 3 detects that the positional relationship between the transport trolley 101 and the shelf 100 matches the preset positional relationship in the controller 4, it indicates that the transport trolley 101 has reached its position. At this time, the controller 4 controls the extension shaft of the drive assembly 2 to extend, so that the first telescopic frame 5 abuts against the first platform 101a of the transport trolley 101, and the second telescopic frame 6 abuts against the second platform 101b of the transport trolley 101. At the same time, the controller 4 controls the extension shaft of the blocking cylinder 71 to retract. In this way, the operator can push the boxes containing materials on the material area 12 of the shelf 100 onto the second telescopic frame 6, and then continue to push the boxes containing materials onto the transport trolley 101. On the second platform 101b, the empty boxes on the first platform 101a of the transport platform 1 are pushed onto the first telescopic frame 5, and then the empty boxes are pushed into the empty box area 11. This completes the exchange between the empty boxes and the boxes containing materials. Then, the operator continues to drive the transport trolley 101 to move along the track to the assembly area, remove the materials and assemble them. After the transport trolley 101 moves away from the shelf 100, when the photoelectric switch 3 detects that the positional relationship between the transport trolley 101 and the shelf 100 does not conform to the preset positional relationship in the controller 4, the controller 4 controls the extension shaft of the drive component 2 to retract. In this way, the first telescopic frame 5 will retract to below the empty box area 11, and the second telescopic frame 6 will retract to below the material area 12. At the same time, the controller 4 controls the extension shaft of the blocking cylinder 71 to extend upward, which can prevent the boxes containing materials in the material area 12 from detaching from the material area 12.

[0042] According to another aspect of this utility model, please refer to Figure 3 and Figure 4The present invention also provides a material transport device 200, including a transport trolley 101 and the aforementioned shelf 100. The transport trolley 101 includes a first platform 101a and a second platform 101b. The first platform 101a is used to place empty boxes, and the second platform 101b is used to place boxes containing materials. The first platform 101a is used to abut against the first telescopic frame 5, and the second platform 101b is used to abut against the second telescopic frame 6. The operator drives the transport trolley 101 along a fixed route. The photoelectric switch 3 on the shelf 100 detects the positional relationship between the transport trolley 101 and the shelf 100 in real time and transmits the positional relationship signal to the controller 4 in real time. When the photoelectric switch 3 detects that the positional relationship between the transport trolley 101 and the shelf 100 matches the preset positional relationship in the controller 4, it indicates that the transport trolley 101 has reached its position. At this time, the controller 4 will control the extension shaft of the drive assembly 2 to extend, so that the first telescopic frame 5 abuts against the first platform 101a of the transport trolley 101, and the second telescopic frame 6 abuts against the second platform 101b of the transport trolley 101. In this way, the operator can push the empty box on the first platform 101a of the transport platform 1 onto the first telescopic frame 5, and then continue to push the empty box onto the first platform 101a. The boxes are pushed to the empty box area 11 and placed there. The boxes containing materials on the material area 12 of the shelf 100 are then pushed onto the second telescopic frame 6. The boxes containing materials are then pushed onto the second platform 101b of the transport trolley 101, thus completing the exchange between empty and material-filled boxes. The operator then continues to drive the transport trolley 101 along the track to the assembly area to remove the materials for assembly. After the transport trolley 101 moves away from the shelf 100, the photoelectric switch 3 detects that the positional relationship between the transport trolley 101 and the shelf 100 does not conform to the preset positional relationship in the controller 4. The controller 4 then controls the extension shaft of the drive assembly 2 to retract, causing the first telescopic frame 5 to retract below the empty box area 11 and the second telescopic frame 6 to retract below the material area 12. Since the material transport device 200 includes all the embodiments of the shelf 100 described above, it possesses at least all the beneficial effects of all the above embodiments, which will not be elaborated upon here.

[0043] Please see Figures 3 to 5In one embodiment, the transport trolley 101 further includes a second blocking member 103, which is disposed on the first platform 101a. The shelf 100 also includes an adjusting rod 51, which is disposed on the first telescopic frame 5. The adjusting rod 51 can abut against the second blocking member 103 to allow the second blocking member 103 to release empty boxes. The operator drives the transport trolley 101 along a fixed route. The photoelectric switch 3 on the shelf 100 detects the positional relationship between the transport trolley 101 and the shelf 100 in real time and transmits the positional relationship signal to the controller 4 in real time. When the photoelectric switch 3 detects that the positional relationship between the transport trolley 101 and the shelf 100 matches the preset positional relationship in the controller 4, it indicates that the transport trolley 101 has reached its position. At this time, the controller 4 will control the extension shaft of the drive assembly 2 to extend, so that the first telescopic frame 5 abuts against the first platform 101a of the transport trolley 101, and the second telescopic frame 6 abuts against the second platform 101b of the transport trolley 101. At the same time, the adjusting rod 51 on the first telescopic frame 5 abuts against the second blocking component 103 on the transport trolley 101. In this way, the operator can push the empty box on the first platform 101a of the transport platform 1 onto the first telescopic frame 5, and then continue to push the empty box onto the second platform 101b. The empty boxes are placed in the empty box area 11. The boxes containing materials on the material area 12 of the shelf 100 are pushed onto the second telescopic frame 6. Then, the boxes containing materials are pushed onto the second platform 101b of the transport trolley 101. This completes the exchange between the empty boxes and the boxes containing materials. Then, the operator continues to drive the transport trolley 101 along the track to the assembly area, removes the materials, and assembles them. After the transport trolley 101 moves away from the shelf 100, the photoelectric switch 3 detects that the positional relationship between the transport trolley 101 and the shelf 100 does not conform to the preset positional relationship in the controller 4. The controller 4 controls the extension shaft of the drive component 2 to retract. In this way, the first telescopic frame 5 will retract to below the empty box area 11, and the second telescopic frame 6 will retract to below the material area 12. The adjusting rod 51 separates from the second blocking component 103, and the second blocking component 103 returns to its original state to prevent the empty boxes from falling off the transport platform 1.

[0044] Please see Figures 3 to 5In one embodiment, the second blocking component 103 includes a touch rod 103a, a pulley block 103b, an elastic line 103c, and a second blocking rod 103d. The touch rod 103a is telescopically mounted on the first platform 101a, and the second blocking rod 103d is telescopically mounted on the first platform 101a in a vertical direction. One end of the elastic line 103c is connected to the touch rod 103a, and the other end of the elastic line 103c is connected to the bottom of the second blocking rod 103d. The elastic line 103c is slidably connected to the pulley block 103b. When the adjusting rod 51 abuts against the touch rod 103a, it pushes the touch rod 103a to move away from the shelf 100, and pulls the second blocking rod 103d downward through the elastic line 103c to release empty boxes. When the adjusting rod 51 abuts against the contact rod 103a, the adjusting rod 51 pushes the contact rod 103a to retract. The elastic line 103c moves with the contact rod 103a. The elastic line 103c, through the angle change of the pulley group 103b, pulls the second blocking rod 103d downward to retract, so that the second blocking rod 103d will not block the empty box from moving off the first platform 101a. When the transport trolley 101 separates from the shelf 100, the adjusting rod 51 separates from the contact rod 103a. The elastic line 103c returns to its original deformation, and the elastic line 103c pulls the contact rod 103a to extend to its original position. At the same time, through the angle change of the pulley group 103b, the elastic force of the elastic line 103c pushes the second blocking rod 103d upward to prevent the empty box from detaching from the first platform 101a.
