Description

Technical Field

[0001] This utility model relates to a lifting mechanism, and more particularly to a lifting mechanism on a conveyor line for lifting a vehicle. Background Technology

[0002] Conveyor lines are used to transport components that make up a product. In the garment manufacturing industry, the main components are fabric pieces. To transport the product, a carrier is needed to move the components. The structure of a conveyor line generally includes a conveyor rail and a flexible drive mechanism adapted to the direction of the rail. The carrier has a traveling unit that attaches to the conveyor rail and moves forward on the rail under the drive mechanism to achieve long-distance transport of components. Conveyor lines generally need to be elevated, while the loading of components usually needs to be done at a lower level, which involves the problem of lifting the carrier loaded with components from a lower to a higher level. In the garment manufacturing industry, this is usually achieved through a lifting arm structure. A shell-shaped lifting arm is inclined at the fabric piece loading station, with a flexible drive belt on the lifting arm. The drive belt has extended push rods, and inclined rails are arranged parallel to the outside of the lifting wall. Driven by a motor, the push rod lifts the hanger holding the fabric piece upwards, allowing it to enter the conveyor rail of the conveyor line. This type of lifting arm is generally only suitable for hangers with single rollers and is not applicable to more complex carriers. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a vehicle lifting mechanism on a conveyor line, which can effectively realize the lifting of relatively complex vehicles and is well adapted to the loading of parts.

[0004] To solve the aforementioned technical problem, the present invention provides the following technical solution: a vehicle lifting mechanism on a conveyor line, installed at the break in the conveyor rail, for lifting a vehicle with a walking mechanism. The structure includes a frame, a lift on the frame, and a connecting frame connected to the lift. The connecting frame has a guide rail section, the outer contours of the guide rail section and the conveyor rail corresponding in cross-section, and the length of the guide rail section corresponding to the break length. The guide rail section supports the walking mechanism. Driven by the lift, the connecting frame moves up and down along the height of the frame, sending the guide rail section into or out of the break position.

[0005] The aforementioned corresponding outer contours generally refer to the fact that their outer contours are identical, but local differences are not excluded. Both the conveyor rail and the guide rail section can adapt to both supporting the traveling part of the vehicle and meeting the traveling requirements of the traveling part. After the vehicle loaded with product parts enters the guide rail section, the guide rail section will rise under the drive of the elevator to enter the aforementioned break position. The guide rail section can bridge the break, thus allowing the vehicle to pass smoothly through the break position. Under normal circumstances, the guide rail section can remain at the break position, forming a passage for other vehicles on the conveyor rail to pass through. It only descends when a new vehicle needs to enter the conveyor rail, but at this time, the drive motor in the conveyor line must stop operating to prevent other vehicles from falling from the break position. Alternatively, the break can be filled by setting a transition rail section to allow other vehicles to pass smoothly through the break position under normal circumstances. The lengths of the guide rail section and transition rail section are generally slightly shorter than the length of the break. When the guide rail section and transition rail section mate with the break, a certain gap will remain, but this gap is generally measured in millimeters and will not affect the normal passage of the vehicle's traveling section. The engagement of the guide rail section and transition rail section with the break can be achieved by using position sensors or by utilizing the end point of the corresponding power structure's stroke, ensuring the guide rail section and transition rail section are properly aligned.

[0006] Furthermore, a translational mechanism is provided on the outer side of the conveyor rail, and a transition section is provided on the translational mechanism. The cross-section of the transition section corresponds to the cross-section of the conveyor rail, and the lengths of the transition section and the guide rail section correspond. The translational mechanism is used to drive the transition section into the break position, or to disengage from the break to make room for the guide rail section to engage with the break. By driving the movement of the transition section through the translational mechanism, the break is filled, so that when it is necessary to lift the carrier loaded with parts, the drive mechanism in the conveyor line does not need to stop working, thereby effectively improving the working efficiency of the conveyor line.

[0007] Furthermore, the translational mechanism is fixedly connected to the upright frame. Directly fixing the translational mechanism to the upright frame facilitates installation, improves the overall integrity of the lifting mechanism, and makes it easy to move the lifting mechanism.

[0008] Furthermore, the translational mechanism includes a fixed frame, which is fixedly connected to the upper end of the upright frame. A sliding structure is provided between the fixed frame and the transition rail section, and a pushing structure is provided between the sliding structure and the fixed frame. The pushing structure is connected to the sliding structure in a transmission manner, and the pushing structure enables the transition rail section to enter the break position or disengage from the break position by staggering it from the guide rail section. The pushing structure can be a cylinder or a hydraulic cylinder, a screw drive structure, or a gear or rack drive structure.

[0009] Furthermore, there are at least two sets of traveling units, arranged at intervals. Each traveling unit has a movable limiting structure on the guide rail section, used to limit the vehicle's position on the guide rail section from the intervals of the traveling units when the vehicle enters the guide rail section. By setting the limiting structure, the vehicle is effectively limited, resulting in good positional stability of the vehicle on the guide rail section.

[0010] Furthermore, the limiting structure includes a limiting head, which is connected to the power structure via a transmission connection. Driven by the power structure, the limiting head is used to extend into or disengage from the interval of the traveling part. The limiting head effectively limits the movement of the vehicle; the structure is simple and facilitates the operation of the limiting head.

[0011] Furthermore, the limiting structure consists of two sets, with limiting heads on each set used to correspondingly limit the movement of the traveling parts at both ends of the interval. When limiting the vehicle on the guide rail section, the movement range of the vehicle on the guide rail section is small, thus the length of the guide rail section does not need to be too large, thereby facilitating the lifting and lowering of the guide rail section and the vehicle.

[0012] Compared with existing technologies, this utility model has the following advantages: By setting a lifting mechanism on the conveyor line, product components can be loaded at a low position and transported over long distances at a high position, resulting in high work efficiency. By setting a connecting frame on the upright frame and a guide rail section on the connecting frame, the carrier can enter the conveyor rail through the cooperation of the guide rail section with the break on the conveyor rail, achieving long-distance transport of product components. It can well adapt to the need for lifting relatively complex carriers, resulting in good stability of the carrier during the lifting process. Attached Figure Description

[0018] Referring to the accompanying drawings, the vehicle lifting mechanism on this conveyor line is located at the break in the conveyor rail and is used to lift the vehicle 5, which has a walking section 51. The lifting mechanism includes a frame 4, which is a frame structure and is vertically mounted on the ground. A lifting mechanism is mounted on the frame 4. The lifting mechanism shown in the figure is a chain and sprocket structure; however, it can also be a cylinder, hydraulic cylinder, or lead screw structure.

[0019] A connecting frame 2 is connected to the lifting platform. The connecting frame 2 is connected to the chain 1. A motor drives the sprocket to rotate, causing the chain 1 to pull the connecting frame 2 up and down on the upright frame 4. Driven by the lifting platform, the connecting frame 2 moves up and down along the height direction of the upright frame 4, sending the guide rail section 3 into or out of the break position. For the stability of the connecting frame 2, a slide rail is generally installed vertically on the upright frame 4. A slider is fixed to the back side of the connecting frame 2, and the slider slides onto the slide rail. The connecting frame 2 is provided with a guide rail section 3, which is installed horizontally. The length of the guide rail section 3 corresponds to the length of the break, and the length of the guide rail section 3 is usually slightly shorter than the length of the break, so that the guide rail section 3 can be directly embedded into the break. Of course, the length of the guide rail section 3 can also be slightly longer than the length of the break. In this case, recesses need to be formed at both ends of the guide rail section 3 to receive the end of the conveyor rail at the break. The outer contours of the cross sections of the guide rail section 3 and the conveyor rail correspond to each other. The guide rail section 3 supports the traveling part 51, which can move forward on the guide rail section 3 and the conveyor rail.

[0020] To ensure that loading product components onto carrier 5 does not impede the smooth passage of other carriers 5 on the conveyor rail through the break point, a translational mechanism is provided on the outer side of the conveyor rail. A transition section 9 is provided on this mechanism. The transition section 9 is generally identical to the guide rail section 3 described earlier in terms of structure, size, and orientation. When the guide rail section 3 leaves the break point, the transition section 9 fills the break point, providing support and passage for other carriers 5 on the conveyor rail. Before the guide rail section 3 enters the break point, the transition section 9 disengages from the break point, providing space for the guide rail section 3 to fill the break point. Limit switches can be installed at the corresponding height of the upright 4. The elevator can be started manually. When the connecting frame 2 descends to the limit switch position, the connecting frame 2 will touch the limit switch from the top. The limit switch will then instruct the translation mechanism to work, so that the transition section 9 fills the break position. When the elevator drives the connecting frame 2 to rise to the limit switch position, the connecting frame 2 will touch the limit switch from the bottom. The limit switch will then instruct the translation mechanism to work in the opposite direction and move the transition section 9 to the outside of the conveyor rail to make way.

[0021] The translational mechanism includes a fixed frame 8, which is fixedly connected to the upper end of the upright frame 4. A sliding structure is provided between the fixed frame 8 and the transition section 9. The sliding structure generally includes a slide rail, and the slider is slidably engaged with the slide rail. The transition section 9 is connected to the slider. The slide rail is generally horizontally arranged. A pushing structure 7 is provided between the sliding structure and the fixed frame 8. The pushing structure 7 shown in the figure is a cylinder. The cylinder body is fixedly connected to the fixed frame 8 or the upright frame 4, and the piston rod in the cylinder is connected to the slider. The cylinder enables the transition section 9 to move out of the guide rail section 3 and into the break position or to disengage from the break position. Under normal circumstances, the transition section 9 moves within the limit stroke range of the piston rod in the cylinder, thereby changing the position of the transition section 9.

[0022] Figure 1 In this system, the carrier 5 has two sets of traveling parts 51, arranged at intervals. The traveling parts 51 are located on the upper side of the carrier 5 and include traveling wheels for rolling support on the conveyor rail, transition rail section 9, and guide rail section 3. A movable limiting structure is provided on the guide rail section 3 to prevent the carrier 5 from sliding off the guide rail section 3 due to component swaying during elevator operation. The limiting structure limits the position of the carrier 5 on the guide rail section 3 at the intervals between the traveling parts 51 when the carrier 5 enters the guide rail section 3, and disengages when the carrier 5 leaves the guide rail section 3. Figure 3 It shows Figure 2 Enlarged view of part A in the image. Figure 3The diagram shows that the limiting structure includes a limiting head 6, which is connected to a power structure. The power structure can be a motor or a cylinder. Under the action of the power structure, the limiting head 6 extends into the interval by deflection or axial extension to limit the travel part 51 of the carrier 5. After the guide rail section 3 reaches the break position, the limiting head 6 disengages to the outside of the interval, and the carrier 5 can enter the conveyor rail from the guide rail section 3 under the push of the drive mechanism.

[0023] Figure 1 As shown in the diagram, there are two sets of walking parts 51 on the vehicle 5, and correspondingly, there are two sets of limiting structures. The limiting heads 6 on the two sets of limiting structures are used to limit the walking parts 51 at both ends of the interval, respectively. Figure 3 The limiting head 6 shown in the figure extends into the gap between the traveling parts 51 in a deflected manner. The end of the limiting head 6 is used to abut against the corresponding traveling part 51 to limit the carrier 5 on the guide rail section 3.

[0024] Figure 4 In the middle, two connecting frames 2 are shown on the upright 4. In fact, there is only one connecting frame 2, and it only lifts one set of vehicles 5 at a time. Figure 4 The loading system, including a robotic arm, is also shown. The upper robotic arm 12 clamps the clamps 52 one by one from the exit end of the guide head 14, and then moves the clamped clamps 52 downwards to the worktable 13. At the worktable 13, the clamps 52 clamp the fabric pieces 10. Then, the lower robotic arm 11 loads the clamps 52 containing the fabric pieces 10 into the carrier 5 located on the guide rail section 3. After the carrier 5 is full of clamps 52, a button is manually pressed to start the elevator, causing the guide rail section 3 to rise with the carrier 5. After pressing the button, the elevator can move according to a fixed stroke, so that the guide rail section 3 is precisely embedded at the break point; alternatively, a limit switch or position sensor can be installed at the break point so that the elevator stops working after the guide rail section 3 has risen to its designated position. The empty vehicle 5 is usually placed near the workbench 13. When it is necessary to load the fabric pieces 10, the guide rail section 3 is lowered into place, and the traveling part 51 on the vehicle 5 is attached to the guide rail section 3, thereby completing the loading preparation work for the fabric pieces 10.
