Abstract
Description
Technical Field
[0001] This utility model relates to the field of production material transportation devices, and in particular to a production line workstation. Background Technology
[0002] During the processing of factory production lines, the handling of workpieces or materials usually requires multiple processes, and most production lines use belt conveyors to transport workpieces.
[0003] In garment production, materials need to be cut, sewn, sized, and packaged. Typically, a single workstation handles only one process, while multiple processes require transfer between them. To improve garment production efficiency, overhead conveyor systems are commonly used to transport garments, not only finished garments but also unfinished items and various raw materials, thereby increasing production efficiency.
[0004] In existing overhead conveyor systems, self-driven carrier robots can move along tracks to transport materials. During transport, the robots pass through various processing stations and enter the stations for processing. The carrier robots and materials usually fall naturally along the tracks to the processing stations by gravity. During the fall, the materials are prone to shaking and may derail, resulting in the loss or damage of production materials. Utility Model Content
[0005] Purpose of the utility model: The purpose of this utility model is to provide a production line workstation that can improve the stability of material conveying and reduce material loss and damage.
[0006] Technical solution:
[0007] A production line workstation includes a mounting frame and a main track connected to the mounting frame. The main track has a discharge port and a loading port. Material conveying devices are connected to the discharge port and the loading port, respectively. The material conveying devices include guide rails fixedly connected to the mounting frame and inclined, and a conveying component that drives a carrier robot to move along the guide rails. A buffer rail is connected between the ends of the two guide rails that are away from the discharge port and the loading port, respectively. The height of the buffer rail is lower than the height of the main track.
[0008] Preferably, the conveying assembly includes a housing fixedly connected to a mounting frame, with a drive wheel and a driven wheel rotatably connected to both ends of the housing, a drive motor for driving the drive wheel to rotate mounted on the housing, and a belt that is simultaneously sleeved on the drive wheel and the driven wheel inside the housing, with multiple levers connected to the belt, and the belt between the drive wheel and the driven wheel is parallel to the guide rail.
[0009] Preferably, photoelectric sensors are provided on the outer casing and the buffer track.

[0017] Beneficial effects:
[0018] When a carrier robot carrying materials needs to enter a workstation for processing, the carrier robot enters the guide rail from the loading port of the main track. The conveying component then moves the carrier robot down the guide rail to the buffer rail, where it stays and waits for processing. After the material processing is completed, another conveying component lifts the carrier robot up to the loading port along the guide rail and then it enters the main track to continue moving. The material conveying device guides the descent and lifting of the carrier robot, reducing the occurrence of collisions and slippage, as well as the loss and damage of production materials.

[0026] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] A production line workstation, such as Figure 1 As shown, it includes a mounting bracket 1 and a main track 2 fixed to the mounting bracket 1 by angle brackets.
[0028] Mounting frame 1 is made of hollow tubing and is equipped with an electrical box 3. By connecting the mains power cable along the main rail 2 and inside the mounting frame 1 to the electrical box 3, the electrical box 3 can output either mains power or low-voltage DC power. The electrical box 3 provides power control for the processing equipment and components at the workstation. An emergency stop button 4 can be installed on the mounting frame 1, coupled to the electrical box 3, for emergency disconnection of power supply to all equipment at that workstation.
[0029] like Figure 2 As 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 discharge port 6 and a loading port 7 are provided on one side of the main track 2. A branch groove 8 is provided between the loading port 7 and the discharge port 6 and the chute 5. The branch groove 8 connects the chute 5 with the loading port 7 or the discharge 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 on the side away from the discharge port 6 into the branch chute 8 and then moves to the discharge port 6.
[0031] After the production materials are processed at this station, the carrier robot enters the chute 5 in the main track 2 from the feed port 7 through the branch groove 8, and continues to run along the main track 2 on the side away from the feed port 7.
[0032] like Figure 3 and Figure 4 As shown, both the unloading port 6 and the loading port 7 are connected to a material conveying device 9, which is used to guide the robot and the materials it carries as they fall and rise.
[0033] The material conveying device 9 includes a guide rail 10 fixedly connected to the mounting frame 1. The guide rail 10 is inclined, and two sets of guide rails 10 located at the loading port 7 and the unloading port 6 are arranged in parallel. A conveying component 11 is provided above the guide rail 10, which 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 docks with the guide track 10. The extension track 12 has the same structure as the main track 2 and also has a chute 5. The end of the extension track 12 away from the guide track 10 is covered and 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 briefly buffered on the extension track 12 when it moves from the main track 2 to the processing station, reducing the impact on the normal operation of other carrier robots.
[0035] RFID readers or electronic tags are installed on the main track 2 and the extended track 12. If the vehicle robot is equipped with an electronic tag, an RFID reader is installed on the main track 2 or the extended track 12 accordingly. If the vehicle robot is equipped with an RFID reader, an electronic tag is installed on the main track 2 or the extended track 12. The location of the vehicle robot can be obtained by reading information between the main track 2 or the extended track 12 and the vehicle robot.
[0036] A buffer track 13 is connected between the ends of the two guide tracks 10 that are away from the discharge port 6 or the loading port 7. The buffer track 13 is fixedly connected to the mounting frame 1, and the height of the buffer track 13 is lower than the height of the main track 2, so that the workers at the workstation can pick up and place materials from the carrier robot.
[0037] The transmission assembly 11 includes a housing 14 fixedly connected to the mounting frame 1, a drive wheel 15 and a driven wheel 16 rotatably connected to the housing 14, a belt 17 sleeved on the drive wheel 15 and the driven wheel 16, a drive motor 18 fixed to the housing 14 for driving the drive wheel 15 to rotate, and a plurality of levers 19 fixedly connected to the belt 17.
[0038] The outer casing 14 is a thin-walled structure with an open bottom. The drive motor 18 is fixedly mounted on the outer casing 14, and the output shaft of the drive motor 18 passes through the outer casing 14 and connects to the drive pulley 15. The belt 17 between the drive pulley 15 and the driven pulley 16 is parallel to the guide rail 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 drive pulley 15 and the driven pulley 16, and the two levers 19 are located at the two ends of the belt 17 that are furthest apart. The running path of the levers 19 between the drive pulley 15 and the driven pulley 16 is parallel to the guide rail 10. When one lever 19 is located near the extension rail 12, the other lever 19 is located near the buffer rail 13.
[0039] like Figure 4 and Figure 5 As shown, the guide rail 10 includes two guide rods 20 arranged in parallel with a gap. Several sets of symmetrically arranged connecting pieces 21 are fixedly connected to the bottom of the housing 14. The two guide rods 20 are fixedly connected to the housing 14 through several connecting pieces 21 located on the same side. There is a space between the guide rods 20 and the housing 14 that can support the passage of the vehicle robot drive unit.
[0040] In order to reduce the impact of external impurities on the operation of the vehicle robot on the guide rail 10, a guard plate 22 is provided above the two guide rods 20. The distance between the two guard plates 22 is greater than the width of the vehicle robot drive unit, and the guard plate 22 is fixedly connected to multiple connecting pieces 21 on the corresponding side.
[0041] The buffer track 13 includes an arc-shaped rail 23 connected to two guide rails 10 respectively and a connecting rail 24 connected between the two arc-shaped rails 23. The buffer track 13 is also provided with a chute 5 for the vehicle robot to pass through. The end of the arc-shaped 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 vehicle robot.
[0042] Photoelectric sensors 25 are respectively installed on the outer shell 14 and the buffer track 13. The photoelectric sensor on the outer shell 14 is used to detect the position of the lever 19, and the photoelectric sensor 25 on the buffer track 13 is used to detect the position of the vehicle robot.
[0043] In this embodiment, a photoelectric sensor 25 is provided on the outer shell 14 located at the feed port 6. The photoelectric sensor 25 is used to detect whether the lever 19 passes by and approaches the extension rail 12.
[0044] A photoelectric sensor 25 is installed on the buffer track 13 located near the feeding port 7. That is, the photoelectric sensor 25 is installed on the arc track 23. 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 installed on the outer casing 14 located at the feed port 7. The photoelectric sensor 25 is used to detect whether the lever 19 passes by and approaches the extension rail 12.
[0046] Since there are two levers 19 symmetrically distributed on the belt 17, when one lever 19 is located at the connection between the guide rail 10 and the extension rail 12 on the same belt 17, the other lever 19 is located at the buffer rail 13 and the guide rail 10. Therefore, the photoelectric sensor 25 on the housing 14 can be set near the extension rail 12 to detect the position of the lever 19, or it can be set near the buffer rail 13 to detect the position of the lever 19.
[0047] In this embodiment, if an RFID reader is installed on the vehicle robot, an electronic tag is installed on the main track 2 located on the side of the unloading port 6 away from the loading port 7; and electronic tags are also installed on the extended tracks 12 at both 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 extended track 12 through the branch groove 8 at the unloading port 6.
[0049] At this time, the vehicle robot reads the electronic tag on the extended track 12, locates its own position, and stops moving to wait. At the same time, the drive motor 18 in the material conveying device 9 corresponding to the discharge port 6 starts. The lever 19 moves with the belt 17, passes the photoelectric sensor 25, and approaches the connection between the guide track 10 and the extended track 12. After the photoelectric sensor 25 is triggered by the passing lever 19, the time it takes for the lever 19 to move to the connection between the guide track 10 and the extended track 12 can be obtained according to the rotation speed of the drive motor 18. Based on this time and the moving speed of the vehicle robot, the start time and start speed of the vehicle robot are confirmed, so that the vehicle robot lands exactly on the lever 19, driving the vehicle robot to slide down the guide track 10 at a constant speed to the bottom of the guide track 10. Based on the rotation speed of the drive motor 18, the vehicle robot can start when it enters the buffer track 13 and move to the corresponding position to wait for material processing.
[0050] After the material carried by the carrier robot is processed, the carrier robot moves towards the guide rail 10 at the loading port 7 and triggers the photoelectric sensor 25 at the buffer rail 13. The drive motor 18 in the material conveying device 9 corresponding to the loading port 7 starts, and the lever 19 drives the carrier robot to rise along the guide rail 10. When the lever 19 triggers the photoelectric sensor 25 at the extension rail 12 near the outer shell 14, the rotation speed of the corresponding drive motor 18 is used to determine the time it takes for the lever 19 to move from the photoelectric sensor 25 to the connection between the guide rail 10 and the extension rail 12. When this time is reached, the carrier robot starts. The carrier robot reads the electronic tag at the extension rail 12 at the loading port 7 to confirm the position of the carrier robot and subsequent movement instructions. The drive unit of the carrier robot starts, passes through the loading port 7 and the branch groove 8, and enters the slide 5 of the main rail 2.
[0051] In this embodiment, the vehicle robot and the photoelectric sensor 25 communicate with the backend server, and the backend server can control the operation, scheduling and adjustment of the drive motor 18 and the vehicle robot.
[0052] The carrier robot enters the extension track 12 from the main track 2, and then enters the guide track 10. As the carrier robot enters the guide track 10, one of the levers 19 is located in front of the drive unit of the carrier robot and supports the drive unit. The drive unit of the carrier robot is mounted between two guide rods 20. Since the guide rods 20 are inclined, the carrier robot slides down the guide rods 20 by gravity. However, due to the obstruction of the lever 19, the carrier robot slides down the guide rods 20 at a stable speed and enters the buffer track 13, thereby keeping the carrier robot stable during the downward slide, reducing the shaking of materials, and reducing the probability of the carrier robot derailing from the track.
[0053] like Figure 6 As shown, a connecting frame 26 is fixedly connected to the mounting frame 1. The connecting frame 26 is fitted outside the connecting rail 24, but the connecting frame 26 does not interfere with the setting of the slide 5. That is, the vehicle robot can move smoothly in the slide 5 of the connecting rail 24. The vertical side wall of the connecting frame 26 is separated from the side wall of the connecting rail 24. A viewing window 27 is opened on the side of the connecting frame 26 away from the mounting frame 1. The area of the viewing window 27 is larger than the projected area of the vehicle robot drive unit. The viewing window can expose the connecting rail 24.
[0054] A maintenance port 28 is provided on the side wall of the connecting rail 24 away from the main rail 2. A connecting groove 29 is provided on the connecting frame 26, which communicates with the maintenance port 28 and extends through the bottom of the connecting frame 26. The maintenance port 28 is connected to the slide groove 5 and the viewing window 27 of the connecting rail 24. A maintenance block 30 is inserted into the maintenance port 28. The upper surface of the maintenance block 30 is flush with the walking surface of the connecting rail 24 for the vehicle robot. An abutment block 31 is fixedly connected to the side of the maintenance block 30 away from the slide groove 5. The abutment block 31 is integrally set with the maintenance block 30 and is placed between the outer wall of the connecting rail 24 and the inner wall of the connecting frame 26. The width of the abutment block 31 is greater than the width of the maintenance block 30. When the maintenance block 30 and the abutment block 31 are removed from the viewing window 27, the drive unit and the connecting unit of the vehicle robot pass through the maintenance port 28.
[0055] The buffer track is covered with a hatch 32, and multiple wireless charging transmitters 33 are installed on the hatch 32 and the side wall of the buffer track. When the vehicle robot moves to the connecting track 24, the wireless charging transmitters 33 can charge the vehicle robot equipped with wireless charging receivers, ensuring the vehicle robot's endurance.
[0056] like Figure 1 As shown, an accessory rack 34 is also fixedly connected to the mounting bracket 1. According to actual production needs, the accessory rack 34 is equipped with at least one of the following: a lamp tube interface, a flat mounting bracket, and a socket.
[0057] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
