Description

Technical Field

[0001] The present invention relates to the technical field of material transfer equipment, and in particular to a horizontal transfer equipment with a spare workstation. Background Art

[0002] Material transfer equipment is widely used in the chemical, food, mining, pharmaceutical, logistics and other industries. It is a commonly used conveying equipment in production, especially in production lines with a high degree of automation. For example, it is used to convey blanks, semi-finished products and finished products in automatic loading and unloading CNC machine tools, and to convey materials between auxiliary material warehouses, finished product storage and finished product outbound warehouses in tobacco automated logistics systems. It has multiple functions such as conveying, sorting and diversion.

[0003] In automated production lines, material transport often involves a "many-to-one" or "one-to-many" process. During the transport process, materials must be combined (moving materials to a single main line) or split (moving materials to multiple branch lines). This requires moving materials to other tracks or locations. Due to the different tracks or routes, additional transfer equipment (such as transfer robots or transfer platforms) is required to meet the material transfer requirements.

[0004] The transfer equipment commonly used in automated production lines today consists of a robotic arm and a transfer station. A motor drives the robotic arm, which uses an end effector (a mechanical gripper, pneumatic gripper, or magnetic suction cup) to grasp the material and then transport it to the target location. Because this multi-axis robotic arm requires a large space, it's not suitable for use in confined spaces. Other types of transfer equipment are also available on the market, including RGV / AGV transfer carts, orienting mechanisms used in automated parts assembly, and conveyor mechanisms.

[0005] The existing vanadium nitride automatic packaging production line involves a series of processes, including raw material crushing, screening, conveying, weighing, and canning. Even with the use of dust removal equipment, dust particles are still generated during the production process, creating a harsh production environment. The vanadium nitride automatic packaging production line requires material conveying and has two material filling ports. After filling, the production line is combined and the filled material is transferred to the main line. If one of the filling ports of the existing transfer equipment on this production line fails or is deactivated, normal circulation will be affected. The influence of dust particles will greatly reduce the service life of the more precise components used in the transfer equipment, such as cylinders, linear guides, and ball screws. Seals, ball sliders, etc. are prone to wear and damage, resulting in high equipment maintenance costs. Summary of the Invention

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] A horizontal transfer device with a spare station, combined with Figure 1 As shown, it includes A material port transfer platform, B material port transfer platform, C horizontal transfer platform, No. 1 transfer trolley 1 and No. 2 transfer trolley 2, among which A material port transfer platform and B material port transfer platform are arranged opposite to each other; C horizontal transfer platform is arranged between A material port transfer platform and B material port transfer platform and forms a cross with A material port transfer platform and B material port transfer platform; A material port transfer platform, B material port transfer platform and C horizontal transfer platform are all provided with support legs at the bottom, and the support legs are used to support the corresponding A material port transfer platform, B material port transfer platform or C horizontal transfer platform.

[0033] A drop port 6 is provided on the A drop port transfer platform in area A, near the C horizontal transfer platform. A drop port 8 is provided on the B drop port transfer platform in area B, near the C horizontal transfer platform. A first guide rail assembly is provided on each of the A drop port 6 and the B drop port 8, with the two sets of first guide rail assemblies positioned opposite each other.

[0034] A second guide rail assembly, perpendicular to the first, is installed on the horizontal transfer platform C. Transfer trolley No. 3 is connected to the second guide rail assembly. A first set of third guide rail assemblies is installed on transfer trolley No. 3 in Zone C 9, near transfer platforms A and B for material port A and B. This first set of third guide rail assemblies can dock with both sets of first guide rail assemblies. Transfer trolley No. 1 and transfer trolley No. 2 are connected to the first guide rail assembly and move between material port A 6, material port B 8, and Zone C 9 via the first set of third guide rail assemblies, which moves with transfer trolley No. 3.

[0035] The end of transfer trolley No. 3, opposite zone C 9, is a standby workstation, zone D 10. Zone D 10 is equipped with a second set of third rail assemblies, which can dock with the two sets of first rail assemblies. Transfer trolley No. 4 is connected to the second set of third rail assemblies. Transfer trolley No. 1, transfer trolley No. 2, and transfer trolley No. 4, driven by transfer trolley No. 3, move between material port A 6, material port B 8, zone C 9, and zone D 10 via the first and third rail assemblies.

[0036] like Figures 4 to 7 As shown, a push plate 11 is provided on the end of the transfer platform A and the transfer platform B, which are away from the horizontal transfer platform C. The push plate 11 is used to push the transfer trolley to move. The bottom of the transfer trolley No. 3 and the bottom of each push plate 11 are respectively connected to a drive mechanism, which includes a drive motor 12 and a transmission assembly 13, wherein the output end of the drive motor 12 is connected to the input end of the transmission assembly 13; the transmission assembly 13 is a chain transmission assembly or a synchronous belt transmission assembly; the bottom of the push plate 11 and the bottom of the transfer trolley No. 3 are respectively connected to the chain of the corresponding chain transmission assembly or the synchronous belt of the synchronous belt transmission assembly. When in use, the corresponding drive motor 12 is driven to drive the chain or synchronous belt on the corresponding transmission component 13 to rotate, thereby driving the No. 3 transfer trolley 3 to move; the corresponding drive motor 12 is driven to drive the chain or synchronous belt on the corresponding transmission component 13 to rotate, thereby driving the push plate 11 to push the other transfer trolleys to move, so that the other transfer trolleys have no power, electrical wires, etc., can shuttle freely, and switch between multiple guide rail assemblies.

[0037] When material 21 falls to the A drop port 6 of area A 5 and the B drop port 8 of area B 7, the No. 1 transfer trolley 1 is used to carry the material 21 at the A drop port 6, and the push plate 11 on the A drop port transfer platform is used to push the No. 1 transfer trolley 1 to move to the C area 9 of the No. 3 transfer trolley 3; at the same time, the empty No. 2 transfer trolley 2 on the C area 9 of the No. 3 transfer trolley 3 moves to the B drop port 8 to prepare to carry the material 21. In this process, the No. 1 transfer trolley 1 pushes the No. 2 transfer trolley 2 to move, and the transfer of the No. 1 transfer trolley 1 and the No. 2 transfer trolley 2 is completed. The No. 3 transfer trolley 3 moves to the designated position, and the material bag in the No. 1 transfer trolley 1 on the C area 9 is taken away by other equipment. At this time, the second group of third guide rail components on the No. 3 transfer trolley 3D area 10 are aligned with the first guide rail components on the A drop port 6 and the B drop port 8. Drive the No. 3 transfer trolley 3 back to its initial position, and the first set of the third guide rail assembly on the C zone 9 of the No. 3 transfer trolley 3 is aligned with the first guide rail assembly on the A drop port 6 and the B drop port 8. At this time, the No. 2 transfer trolley 2 on the B drop port 8 carries the material 21, and the push plate 11 on the transfer platform of the B drop port pushes the No. 2 transfer trolley 2 to move. The No. 2 transfer trolley 2 pushes the No. 1 transfer trolley 1 back to the A drop port 6, and the No. 2 transfer trolley 2 stays in the C zone 9 of the No. 3 transfer trolley 3. This process is the normal working mode, and the No. 1 transfer trolley 1 and the No. 2 transfer trolley 2 work alternately and reciprocatingly. The process is as follows Figure 2 shown.

[0038] When a material drop port needs to be repaired, transfer trolley No. 4 in zone D 10 of transfer trolley No. 3 needs to be activated. For example, when material drop port B 8 needs to be repaired (without affecting the transfer equipment) and material drop port A 6 can operate normally, after transfer trolley No. 1 of material drop port A 6 carries material 21, the push plate 11 on the transfer platform of material drop port A pushes transfer trolley No. 1 to zone C 9 of transfer trolley No. 3. At this time, transfer trolley No. 2 in zone C 9 of transfer trolley No. 3 moves to material drop port B 8. Transfer trolley No. 3 advances to the designated position and waits for other equipment to remove material 21 from transfer trolley No. 1. At this time, the second set of third guide rail assemblies on zone D of transfer trolley No. 3 are aligned with the first guide rail assemblies on material drop ports A 6 and B 8. The push plate 11 on the transfer platform of the B blanking port pushes the No. 2 transfer trolley 2 to move to the D zone 10 of the No. 3 transfer trolley 3. The No. 4 transfer trolley 4 on the D zone 10 of the No. 3 transfer trolley 3 moves to the A blanking port 6 and waits at the A blanking port 6 to carry the material 21. The No. 3 transfer trolley 3 is driven back to the initial position, and the first set of the third guide rail assembly on the C zone 9 of the No. 3 transfer trolley 3 is aligned with the first guide rail assembly on the A blanking port 6 and the B blanking port 8. The No. 4 transfer trolley 4 moves to the C zone 9, the No. 2 transfer trolley 2 moves to the A blanking port 6, and the No. 1 transfer trolley 1 moves to the D zone 10. The three transfer trolleys circulate and stay in the four areas of the A blanking port 6, the B blanking port 8, the C zone 9 and the D zone 10 to complete the work. The process is as follows Figure 3 shown.

[0039] Transfer trolley No. 1, transfer trolley No. 2, transfer trolley No. 3, and transfer trolley No. 4 are all provided with a U-shaped track wheel 14 on one side of their bottoms, and a T-shaped track wheel 15 on the other side of their bottoms. The first guide rail assembly, the second guide rail assembly, and the third guide rail assembly each include a linear guide rail A 16 and a linear guide rail B 17. The linear guide rail A 16 and the linear guide rail B 17 are parallel to each other, wherein the linear guide rail A 16 is adapted to and connected to the U-shaped track wheel 14; the linear guide rail B 17 is adapted to and connected to the T-shaped track wheel 15. For details, please refer to Figures 5 to 7 The transfer trolley uses U-shaped and T-shaped rail wheels to move on two types of linear guides. It can be used in a certain dusty environment and has a certain degree of accuracy.

[0040] Area A 5, Area B 7, Area C 9 and Area D 10 are respectively provided with baffles 18 symmetrically arranged on both sides of the guide rail assembly. Ball screws 19 are respectively provided at specific positions on the baffles 18. For details, please refer to Figures 5 and 6 , buckles are provided at specific positions on the No. 1 transfer trolley 1, the No. 2 transfer trolley 2, and the No. 4 transfer trolley 4. When the No. 1 transfer trolley 1, the No. 2 transfer trolley 2, and the No. 4 transfer trolley 4 stop at the designated positions of the A drop port 6, the B drop port 8, the C area 9, or the D area 10, the buckles are connected to the ball screws 19, which can ensure that the No. 1 transfer trolley 1, the No. 2 transfer trolley 2, and the No. 4 transfer trolley 4 do not move during the movement of the No. 3 transfer trolley 3 after they stop at the designated positions of the A drop port 6, the B drop port 8, the C area 9, or the D area 10.

[0041] Two electromagnets 20 are respectively provided on the side of area A 5 and area B 7 away from the No. 3 transfer trolley 3. The two electromagnets 20 are respectively located in front of the two sides of the corresponding push plate 11, so as not to affect the movement of the push plate 11. For details, see Figure 4 . The electromagnet 20 is used to stop the transfer trolley No. 1, transfer trolley No. 2 and transfer trolley No. 4 at the designated positions of the A blanking port 6 or the B blanking port 8 when the transfer trolley No. 1, transfer trolley No. 2 and transfer trolley No. 4 move to the designated positions of the A blanking port 6 or the B blanking port 8 respectively, and not to move with the movement of the No. 3 transfer trolley 3. Taking the transfer trolley No. 1 as an example, when the transfer trolley No. 1 moves to the designated position of the A blanking port 6, the electromagnet 20 just contacts the transfer trolley No. 1. At this time, the electromagnet 20 will adsorb the transfer trolley No. 1, making the transfer trolley No. 1 unable to move; when the transfer trolley No. 1 needs to move, the electromagnet 20 is powered off and releases the transfer trolley No. 1.

[0042] At the A blanking port 6 and the B blanking port 8, the ball screw 19 and the electromagnet 20 work together to limit the No. 1 transfer trolley 1, the No. 2 transfer trolley 2 and the No. 4 transfer trolley 4, so that the No. 1 transfer trolley 1, the No. 2 transfer trolley 2 and the No. 4 transfer trolley 4 can be better stopped at the specified position of the A blanking port 6 or the B blanking port 8 without being displaced by the movement of the No. 3 transfer trolley 3.

[0043] When in use, the present invention can be applied to a precise packaging system for vanadium nitride particles based on process control technology, by setting the A drop port transfer platform, the B drop port transfer platform and the C horizontal transfer platform, and the No. 1 transfer trolley 1, the No. 2 transfer trolley 2 and the No. 3 transfer trolley 3 set on the A drop port transfer platform, the B drop port transfer platform and the C horizontal transfer platform, the No. 1 transfer trolley 1 and the No. 2 transfer trolley 2 can be used to alternately transport the materials 21 of the two drop ports A drop port 6 and the B drop port 8. To area C 9 of the No. 3 transfer trolley 3, so that the material 21 can be taken away by other equipment; by adding a spare workstation area D 10 and a No. 4 transfer trolley 4 to the No. 3 transfer trolley 3, it can continue to work relying on only one blanking port, so that the No. 1 transfer trolley 1, the No. 2 transfer trolley 2 and the No. 4 transfer trolley 4 can move between the A blanking port 6, the B blanking port 8 and the D area 10 and transport the material 21 to area C 9 of the No. 3 transfer trolley 3, so that the material 21 can be taken away by other equipment, thereby not affecting production.

[0044] By using a combination of two guide rails and two rail wheels to move the transfer trolley, the production environment requirements are lowered, it can be used in a certain dust environment, and has a certain degree of precision.

[0045] The transfer trolley is pushed by the push plate 11 on the chain or synchronous belt, so that the transfer trolley can move without power, electrical wires, etc., which not only allows the trolley to shuttle freely and switch between multiple tracks, but also has low requirements on the production environment and low maintenance costs.

[0046] By installing the clips at specific positions of the No. 1 transfer trolley 1, the No. 2 transfer trolley 2 and the No. 4 transfer trolley 4 and the ball screws 19 at specific positions of area A 5, area B 7 and area C 9 and area D 10 of the No. 3 transfer trolley 3, the No. 1 transfer trolley 1, the No. 2 transfer trolley 2 and the No. 4 transfer trolley 4 can be stopped at the specified positions of the A drop port 6, the B drop port 8, the C area 9 or the D area 10, ensuring that they will not be displaced during the movement of the No. 3 transfer trolley 3.

[0047] By setting the electromagnets 20 respectively on the side of area A 5 and area B 7 away from the No. 3 transfer trolley 3, they can work together with the ball screw 19 to further make the No. 1 transfer trolley 1, the No. 2 transfer trolley 2 and the No. 4 transfer trolley 4 stop at the specified position of the A blanking port 6 or the B blanking port 8 without moving with the No. 3 transfer trolley 3.
