Description

Technical Field

[0001] The present invention relates to the technical field of production material transportation devices, and particularly to a production line workstation. Background Art

[0002] During the processing of factory production lines, the processing of workpieces or materials usually requires multiple processes. Most production lines use belts for the transportation of workpieces.

[0003] When carrying out clothing production and processing, it is necessary to cut, sew, size and package the materials. Usually, a single workstation only performs a single process, and transfer processing is required between multiple processes. In order to improve the production efficiency of clothing, hanging conveying equipment is usually used to convey clothing. Not only finished clothes, but also unfinished and various unprocessed materials can be transported through the hanging conveying equipment, thereby improving the production efficiency.

[0004] In the existing hanging transportation equipment, a self-driven carrier robot can move in the track to achieve the transportation of materials. During transportation, it will pass through each processing station and enter the processing station for processing. The carrier robot and the materials usually naturally fall along the track under the action of gravity to the processing station. During the falling process, the materials are prone to shaking and may deviate from the track, resulting in the loss and damage of production materials. Summary of the Invention

[0005] Object of the Invention: The object of the present invention is to provide a production line workstation, which can improve the transportation stability of production materials and reduce the loss and damage of production materials.

Detailed implementation manners

[0026] To make the technical solutions of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments.

[0027] A production line workstation, as Figure 1 shown, includes a mounting frame 1 and a main track 2 fixed to the mounting frame 1 through angle codes.

[0028] The mounting frame 1 is made of a hollow pipe, and an electrical box 3 is provided on the mounting frame 1. By connecting the municipal wire cable along the main track 2 and inside the mounting frame 1 to the electrical box 3, the electrical box 3 can output municipal power or low-voltage direct current. The electrical box 3 provides power control for the station processing equipment and each component. And an emergency stop button 4 can be provided on the mounting frame 1, and the emergency stop button 4 is coupled to the electrical box 3 for emergently cutting off the power supply of all electrical equipment at this station.

[0029] As Figure 2 shown, a chute 5 is provided on the main track 2, and the carrier robot runs along the chute 5. At the processing station, a blanking port 6 and a loading port 7 are opened on one side of the main track 2. A fork slot 8 is provided between the loading port 7 and the blanking port 6, and the fork slot 8 communicates the chute 5 with the loading port 7 or the blanking port 6.

[0030] When the production materials need to be processed, the carrier robot carries the materials from the chute 5 in the main track 2 away from the material discharge port 6 into the fork slot 8 and then moves to the material discharge port 6;

[0031] After completing the processing of the production materials at the workstation, the carrier robot enters the chute 5 in the main track 2 from the loading port 7 through the fork slot 8 and continues to run along the main track 2 away from the loading port 7.

[0032] like Figure 3 and Figure 4 As shown, both the unloading port 6 and the loading port 7 are connected with a material conveying device 9, and the material conveying device 9 is used to guide the falling and lifting of the carrier robot and the carried materials.

[0033] The material conveying device 9 includes a guide rail 10 fixedly connected to the mounting frame 1. The guide rail 10 is arranged at an angle, and two sets of guide rails 10 located at the loading port 7 and the unloading port 6 are arranged in parallel. A conveying assembly 11 is arranged above the guide rail 10, and the conveying assembly 11 is used to drive the carrier robot to move along the guide rail 10.

[0034] The main track 2 is also fixedly connected to an extension track 12 that is docked with the guide track 10. The structure of the extension track 12 is the same as that of the main track 2. The extension track 12 also has a slide groove 5. The end of the extension track 12 away from the guide track 10 covers and is connected to the loading port 7 or the unloading port 6. The carrier robot moves from the main track 2 to the extension track 12 and then to the guide track 10, so that the carrier robot can be temporarily cached on the extension track 12 when moving from the main track 2 to the processing station, thereby reducing the impact on the normal operation of other carrier robots.

[0035] RFID readers or electronic tags are provided on the main track 2 and the extended track 12. If the carrier robot is installed with an electronic tag, an RFID reader is installed on the main track 2 or the extended track 12 accordingly. If the carrier robot is installed with an RFID reader, an electronic tag is installed on the main track 2 or the extended track 12. The position of the carrier robot can be acquired by reading information between the main track 2 or the extended track 12 and the carrier robot.

[0036] A cache rail 13 is connected between the ends of the two guide rails 10 that are respectively away from the unloading port 6 or the loading port 7. The cache rail 13 is fixedly connected to the mounting frame 1, and the height of the cache rail 13 is lower than the height of the main rail 2, which is convenient for workers at the workstation to take and place materials from the carrier robot.

[0037] The transmission assembly 11 includes a shell 14 fixedly connected to the mounting frame 1, a driving wheel 15 and a driven wheel 16 rotatably connected to the shell 14, a belt 17 simultaneously sleeved on the driving wheel 15 and the driven wheel 16, a driving motor 18 fixed to the shell 14 for driving the driving wheel 15 to rotate, and a plurality of levers 19 fixedly connected to the belt 17.

[0038] The housing 14 is a thin-walled structure with an opening at the bottom. The drive motor 18 is fixedly mounted on the housing 14, and the output shaft of the drive motor 18 passes through the housing 14 and is connected to the driving wheel 15. The belt 17 between the driving wheel 15 and the driven wheel 16 is parallel to the guide track 10. In this embodiment, two levers 19 are provided. The two levers 19 are located on the side of the belt 17 away from the driving wheel 15 and the driven wheel 16, and the two levers 19 are respectively located at the two ends of the belt 17 that are farthest apart. The running path of the lever 19 between the driving wheel 15 and the driven wheel 16 is parallel to the guide track 10. When one lever 19 is located near the extended track 12, the other lever 19 is located near the cache track 13.

[0039] like Figure 4 and Figure 5 As shown, the guide rail 10 includes two guide rods 20 that are spaced apart and arranged in parallel, and a plurality of groups of symmetrically arranged connecting plates 21 are fixedly connected to the bottom of the outer shell 14. The two guide rods 20 are respectively fixedly connected to the outer shell 14 through a plurality of connecting plates 21 located on the same side, and there is a space between the guide rods 20 and the outer shell 14 that can support the passage of the carrier robot driving unit.

[0040] In order to reduce the impact of external impurities on the carrier robot when it runs on the guide rail 10, a guard plate 22 is arranged above the two guide rods 20. The distance between the two guard plates 22 is greater than the width of the carrier robot driving part, and the guard plate 22 is fixedly connected to multiple connecting plates 21 on the corresponding side.

[0041] The cache rail 13 includes an arc rail 23 respectively connected to the two guide rails 10 and a connecting rail 24 connected between the two arc rails 23. The cache rail 13 is also provided with a slide groove 5 for the carrier robot to pass through. The end of the arc rail 23 away from the connecting rail 24 is inclined upward and the upper surface is flush with or slightly lower than the contact surface between the guide rail 10 and the carrier robot.

[0042] Photoelectric sensors 25 are respectively provided on the housing 14 and the cache track 13 . The photoelectric sensor on the housing 14 is used to detect the position of the lever 19 , and the photoelectric sensor 25 on the cache track 13 is used to detect the position of the carrier robot.

[0043] In this embodiment, a photoelectric sensor 25 is provided on the housing 14 located at the material discharge port 6, and the photoelectric sensor 25 is used to detect whether the lever 19 passes through and approaches the extended track 12;

[0044] A photoelectric sensor 25 is provided at the buffer track 13 near one side of the loading port 7, that is, the photoelectric sensor 25 is arranged on the arc track 23, and the photoelectric sensor 25 is used to detect whether there is a carrier robot that needs to be lifted to the main track 2;

[0045] A photoelectric sensor 25 is provided on the outer shell 14 at the loading port 7, and the photoelectric sensor 25 is used to detect whether the lever 19 passes by and approaches the extension track 12.

[0046] Since two levers 19 are provided and symmetrically distributed on the belt 17, that is, on the same belt 17, when one lever 19 is located at the connection of the guiding track 10 and the extension track 12, the other lever 19 is located at the buffer track 13 and the guiding track 10. Therefore, the position of the photoelectric sensor 25 on the outer shell 14 can be set near the extension track 12 to detect the position of the lever 19, or can be set near the buffer track 13 to detect the position of the lever 19.

[0047] In this embodiment, it is set that an RFID card reader is installed on the carrier robot, and an electronic tag is installed on the main track 2 on the side of the unloading port 6 away from the loading port 7; and electronic tags are installed on the extension tracks 12 at the loading port 7 and the unloading port 6.

[0048] According to its own path planning, when the carrier robot reads the electronic tag at the unloading port 6 and confirms that the corresponding processing station is the station that the carrier robot needs to enter, the carrier robot enters the extension track 12 through the fork slot 8 at the unloading port 6;

[0049] At this time, the carrier robot reads the electronic tag on the extension track 12, locates its own position, and stops moving and waits. At the same time, the drive motor 18 in the corresponding material conveying device 9 at the unloading port 6 starts, and the lever 19 moves along with the belt 17 and approaches the connection of the guiding track 10 and the extension track 12 after passing by the photoelectric sensor 25. After the photoelectric sensor 25 is triggered by the passing lever 19, the time for the lever 19 to move to the connection of the guiding track 10 and the extension track 12 can be obtained according to the rotation speed of the drive motor 18, and the start time and start speed of the carrier robot are confirmed according to this time and the moving speed of the carrier robot, so that the carrier robot just lands on the lever 19, drives the carrier robot to slide down along the guiding track 10 at a uniform speed to the bottom end of the guiding track 10, and can start when the carrier robot enters the buffer track 13 according to the rotation speed of the drive motor 18, and moves to the corresponding position to wait for material processing;

[0050] After the material carried by the vehicle robot is processed, the vehicle robot travels towards the guiding track 10 at the loading port 7 and triggers the optoelectronic sensor 25 at the buffer track 13. The drive motor 18 in the corresponding material conveying device 9 at the loading port 7 starts, and the lever 19 drives the vehicle robot to ascend along the guiding track 10. When the lever 19 triggers the optoelectronic sensor 25 near the extension track 12 of the housing 14, the time for the lever 19 to move from the position of the optoelectronic sensor 25 to the connection of the guiding track 10 and the extension track 12 is confirmed according to the rotation speed of the corresponding drive motor 18, and the vehicle robot is started when this time arrives. The vehicle robot reads the electronic tag at the extension track 12 at the loading port 7 to confirm its position and subsequent travel instructions, and the drive part of the vehicle robot starts and enters the chute 5 of the main track 2 after passing through the loading port 7 and the fork slot 8.

[0051] In this embodiment, the vehicle robot and the optoelectronic sensor 25 both communicate with the background server, and the operation, scheduling, and adjustment of the drive motor 18 and the vehicle robot can be controlled through the background server.

[0052] The vehicle robot enters the extension track 12 from the main track 2 and then enters the guiding track 10. When the vehicle robot enters the guiding track 10, one of the levers 19 is located in front of the drive part of the vehicle robot and supports the drive part of the vehicle robot. The drive part of the vehicle robot is mounted between two guiding rods 20. Since the guiding rods 20 are inclined, the vehicle robot slides downward along the guiding rods 20 by gravity. However, due to the blocking of the lever 19, the vehicle robot slides along the guiding rods 20 at a stable speed and enters the buffer track 13, so that the vehicle robot remains stable during the downward sliding process, reducing the shaking of the material and the probability of the vehicle robot deviating from the track.

[0053] As Figure 6 shown, a connection frame 26 is fixedly connected to the mounting bracket 1. The connection frame 26 is sleeved outside the connection rail 24, but the connection frame 26 does not interfere with the setting of the chute 5, that is, the vehicle robot can move smoothly in the chute 5 of the connection rail 24. There is a gap between the vertical side wall of the connection frame 26 and the side wall of the connection rail 24, and a viewing window 27 is opened on the side of the connection frame 26 away from the mounting bracket 1. The area of the viewing window 27 is larger than the projected area of the drive part of the vehicle robot, and the viewing window can expose the connection rail 24.

[0054] An inspection opening 28 is provided on the side wall of the connecting rail 24 away from the main rail 2. A connecting groove 29 communicating with the inspection opening 28 is provided on the connecting frame 26, and the connecting groove 29 penetrates through the bottom of the connecting frame 26. The inspection opening 28 communicates with the chute 5 and the viewing window 27 of the connecting rail 24. An inspection block 30 is inserted at the inspection opening 28. The inspection block 30 is inserted into the inspection opening 28, and the upper surface of the inspection block 30 is flush with the walking surface of the connecting rail 24 for the vehicle robot. A butting block 31 is fixedly connected to the side of the inspection block 30 away from the chute 5. The butting block 31 is integrally provided with the inspection block 30. The butting block 31 is placed between the outer side wall of the connecting rail 24 and the inner wall of the connecting frame 26, and the width of the butting block 31 is greater than the width of the inspection block 30. When the inspection block 30 and the butting block 31 are removed from the viewing window 27, the driving part and the connecting part of the vehicle robot pass through the inspection opening 28.

[0055] A hatch cover 32 is provided on the buffer track. A plurality of wireless charging transmitting devices 33 are provided on the hatch cover 32 and the side wall of the buffer track. When the vehicle robot moves to the connecting rail 24, the wireless charging transmitting device 33 can charge the vehicle robot equipped with a wireless charging receiving device to ensure the battery life of the vehicle robot.

[0056] As Figure 1 shown, a fitting rack 34 is also fixedly connected to the mounting rack 1. According to actual production needs, the fitting rack 34 is provided with at least one of a lamp tube interface, a flat mounting rack, and a socket.

[0057] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
