Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of fabric conveying technology, specifically to a front-end fabric conveying device for ceiling molding. Background Technology
[0002] In the rapid development of the automotive manufacturing industry, the headliner, as one of the core components of automotive interiors, directly affects the quality and production cycle of the entire vehicle interior through the quality and efficiency of its molding process. In the headliner molding process, the conveying, positioning, and state adjustment (such as flipping) of the front-end fabric are key preliminary steps, ensuring that the fabric remains flat, accurately positioned, and conforms to the process orientation requirements before entering the molding die.
[0003] Currently, the conveying of the headliner front-end fabric relies heavily on traditional conveyor belt mechanisms. These conveyor belts often employ single-belt drive or dual-belt asynchronous drive. During conveying, the fabric is prone to shifting due to uneven force on both sides, leading to misalignment between the fabric edges and the mold during subsequent molding, affecting molding accuracy. Some fabrics require 180° flipping according to process requirements, such as distinguishing the front and back sides or adjusting the texture direction. Existing flipping mechanisms mostly use single-clamping-point flipping or manual-assisted flipping. Single-clamping-point flipping easily causes wrinkles in the fabric due to concentrated force, while manual flipping is inefficient and makes it difficult to ensure consistent flipping angles. The width of headliner fabrics varies between different car models, and the fixed or cumbersome adjustment of the conveyor belt spacing in traditional conveying mechanisms (requiring disassembly and reassembly) makes it difficult to quickly adapt to multiple fabric specifications, restricting the flexible production capacity of the production line. At the same time, the low level of automation means that the linkage between fabric arrival detection, clamping, flipping, and conveying relies heavily on manual judgment, lacking closed-loop control of sensors and actuators. This makes it easy for human error to cause process interruptions, affecting production continuity. Utility Model Content

[0030] See attached document Figures 1-5 A front-end fabric conveying device for ceiling molding includes a workbench 1, a conveying mechanism 4 on the workbench 1 for conveying the front-end fabric of the ceiling, a vertically fixed lifting linear module 2 on the workbench 1, the fixed end of the lifting linear module 2 being fixedly connected to the workbench 1 via a frame, and a flipping mechanism 3 on the moving end of the lifting linear module 2, the flipping mechanism 3 being positioned above the conveying mechanism 4, and the flipping center axis of the flipping mechanism 3 being parallel to the conveying direction of the conveying mechanism 4.
[0031] The flipping mechanism 3 includes a lifting plate 31, which is fixedly connected to the moving end of the lifting linear module 2. A double-headed cylinder 32 is fixed in the middle of the bottom surface of the lifting plate 31. A mounting plate 33 is fixed to the ends of the two piston rods of the double-headed cylinder 32. A rotary cylinder 36 is fixed to the outside of each mounting plate 33. A clamping block 37 is fixed to the end of the output shaft of the rotary cylinder 36. A clamping groove 38 adapted to the fabric thickness is opened on the side of the clamping block 37 facing the other clamping block 37. The clamping grooves 38 of the two clamping blocks 37 are arranged opposite to each other.
[0032] The bottom surface of the lifting plate 31 is fixed with a guide rail 34 along the conveying direction of the conveying mechanism 4. Two sliders 35 are slidably connected on each guide rail 34. The two piston rods of the double-headed cylinder 32 extend along the length of the guide rail 34 respectively. The mounting plate 33 is fixedly connected to the corresponding slider 35.
[0033] The conveying mechanism 4 includes a first conveyor belt 401 and a second conveyor belt 402 arranged symmetrically. The fabric is mounted on the first conveyor belt 401 and the second conveyor belt 402. A photoelectric sensor 403 for detecting the position of the fabric is installed on the second conveyor belt 402.
[0034] A lifting cylinder 404 is provided between conveyor belt 1 401 and conveyor belt 2 402. The fixed end of the lifting cylinder 404 is fixed on the worktable 1, and the output end of the lifting cylinder 404 is fixedly connected to the lifting plate 405.
[0035] The drive pulleys 406 of conveyor belt 1 401 and conveyor belt 2 402 are both fixed on a hexagonal shaft 407. A motor base 413 is fixedly installed on the worktable 1. A motor 408 is fixedly installed on the motor base 413. The motor 408 is fixedly connected to the hexagonal shaft 407. The hexagonal shaft 407 is rotatably mounted on the motor base 413.
[0036] The lower end of conveyor belt 401 is mounted on workbench 1 via a fixed base 412. Two guide rails 409 are mounted on workbench 1. Two sliders 410 are fixedly mounted on the lower end of conveyor belt 402. Each slider 410 is slidably mounted on one guide rail 409. A locking mechanism 411 is provided on each slider 410. The locking mechanism 411 can be a knob-bolt type or a pin type.
[0037] Working principle:
[0038] Based on the width specifications of the fabric at the front of the canopy, operate the slider 410 of conveyor belt 402, release the locking mechanism 411 on slider 410, and allow slider 410 to slide along guide rail 409 on worktable 1, thereby adjusting the distance between conveyor belt 401 and conveyor belt 402 until it matches the fabric width. After adjustment, fix slider 410 to guide rail 409 using locking mechanism 411 to ensure a stable distance between conveyor belt 401 and conveyor belt 402.
[0039] Place the fabric at the front end of the canopy onto conveyor belts 401 and 402, ensuring both ends of the fabric are positioned on the two conveyor belts and the front ends are aligned along the conveying direction. Start motor 408, which drives hexagonal shaft 407 to rotate. Since the drive pulleys 406 of both conveyor belts 401 and 402 are fixed to hexagonal shaft 407, the hexagonal shaft 407 drives the two drive pulleys 406 to rotate synchronously, causing conveyor belts 401 and 402 to run synchronously. The fabric is then conveyed along the conveyor belts towards the turning mechanism 3.
[0040] When the front end of the fabric moves to the detection area of the photoelectric sensor 403 on the second conveyor belt 402, the photoelectric sensor 403 triggers a signal, which is fed back to the control system. The control system controls the motor 408 to stop running, and the first conveyor belt 401 and the second conveyor belt 402 stop conveying. The fabric stops precisely under the flipping mechanism 3.
[0041] The control system drives the lifting cylinder 404 to move. The output end of the lifting cylinder 404 drives the lifting plate 405 to rise. The lifting plate 405 lifts the middle of the fabric from the gap between the first conveyor belt 401 and the second conveyor belt 402, so that the fabric is kept flat and avoids sagging due to its own weight, which would cause it to be not firmly clamped.
[0042] The moving end of the lifting linear module 2 is activated, which drives the lifting plate 31 to descend, causing the flipping mechanism 3 to move down as a whole until the clamping block 37 reaches the clamping height on both sides of the fabric.
[0043] The two piston rods of the double-headed cylinder 32 retract along the guide rail 34, pulling the mounting plate 33 connected to the piston rods. The mounting plate 33 moves smoothly along the guide rail 34 via the slider 35, causing the two rotary cylinders 36 to synchronously approach the fabric. When the clamping grooves 38 of the two clamping blocks 37 are aligned with the sides of the fabric, the double-headed cylinder 32 stops moving, and the clamping grooves 38 clamp the sides of the fabric, completing the clamping process.
[0044] The moving end of the lifting linear module 2 drives the lifting plate 31 to rise, and the rotary cylinder 36 is activated. Its output shaft drives the clamping block 37 and the clamped fabric to rotate around the "turning center axis parallel to the conveying direction of the conveying mechanism 4". If it is turned 180° according to the process requirements, the fabric can be turned over. During the turning process, since the clamping block 37 is stably supported by the slider 35 along the guide rail 34, and the rotation axis is parallel to the conveying direction, the turning angle can be accurately guaranteed and the fabric will not deviate.
[0045] The moving end of the lifting linear module 2 lowers the lifting plate 31, stopping the rotary cylinder 36 and keeping the fabric in its flipped state. The piston rod of the double-headed cylinder 32 extends, causing the mounting plate 33, rotary cylinder 36, and clamping block 37 to move in the opposite direction along guide rail 34, releasing the fabric. The moving end of the lifting linear module 2 then raises the lifting plate 31 and flipping mechanism 3 as a whole, returning to the initial high position. The output end of the lifting cylinder 404 retracts, causing the lifting plate 405 to descend, detaching from the fabric and returning to the initial position between conveyor belt 401 and conveyor belt 402.
[0046] The control system restarts the motor 408, driving the hexagonal shaft 407 and conveyor belts 401 and 402 to run again, continuing to convey the flipped fabric forward until it is sent to the next process of molding on the ceiling, completing one conveying-flipping cycle.
[0047] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, 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 modifications and improvements 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.
