Description

Technical Field

[0001] This utility model relates to the field of automobile roof production technology, and in particular to an automatic material switching device for an automobile roof production line. Background Technology

[0002] In the automotive headliner manufacturing industry, products are typically made from multiple layers of composite materials. Current processing techniques involve a two-step process, with each step combining two specific materials. These materials are supplied in roll form, with varying diameters ranging from 300 to 600 mm.

[0003] In the specific production process: Workers place each layer of raw material rolls on their respective racks. Then, after completely overlapping each layer, the workers pull it to the feeding roller assembly. This assembly consists of an upper roller and a lower roller. The upper roller is raised and lowered using a cylinder, while the lower roller is fixed in a specific position, with one side of its shaft connected to a drive motor. During operation, one end of the overlapped raw material is first pulled between the two rollers. The upper roller is then lowered to press the material down. Next, the drive motor is started, causing the lower roller to rotate. The upper roller moves synchronously with the material, allowing it to be conveyed forward. Following this, the material continues forward after passing the cutting blade until its front end is gripped by the material-pulling jaws. At this point, the conveying rollers continue feeding. When the material conveying length reaches a set value, the material-pulling jaws and the conveying rollers stop synchronously. Subsequently, the profile directly above the cutting blade lowers to press the material down, the cutting blade cuts the material, and after cutting, the profile returns to its original position. The material-pulling jaws then pull the cut material to a designated position and return to their initial waiting position, preparing for the next material pull.

[0004] However, the existing process has significant drawbacks: after each roll of raw material is used up, the equipment must be stopped for roll changing, with each downtime lasting approximately 10-15 minutes. At least 10 roll changes are required daily, accumulating to 100-150 minutes of downtime. This not only necessitates a large number of staff for roll changing and auxiliary operations, increasing production costs, but also severely restricts production efficiency due to the frequent and prolonged downtime, making it difficult to meet the demands of large-scale production.

[0005] Therefore, it is necessary to improve existing technologies. Utility Model Content

[0006] This utility model aims to at least partially solve one of the problems existing in the prior art. To this end, this utility model proposes an automatic material switching device for an automobile roof production line, which can achieve the effect of automatic material switching and improve production efficiency.

[0007] The above objective is achieved through the following technical solution:

[0008] An automatic material switching device for an automotive roof production line cuts raw materials and includes a material preparation mechanism, a cutting mechanism, a storage mechanism, and an electrical control system. The material preparation mechanism is located in front of the cutting mechanism, and the storage mechanism is located behind the cutting mechanism. After the raw materials are installed on the material preparation mechanism, they are pulled onto the cutting mechanism for cutting. After the raw materials are cut, they are placed in the storage mechanism for storage. The material preparation mechanism, the cutting mechanism, and the storage mechanism are all electrically connected to the electrical control system.

[0009] In some embodiments, the material preparation mechanism includes a first frame, an electric hoist, mounting chucks, and air shafts. The electric hoist is disposed on the upper side of the first frame, a plurality of mounting chucks are disposed on the lower side of the first frame, and a plurality of air shafts are inserted into the rolled raw material. The electric hoist lifts the rolled raw material, and both ends of the air shafts are inserted into the mounting chucks. The rolled raw material rotates freely between the mounting chucks, and the raw material is transmitted from the material preparation mechanism to the cutting mechanism.

[0010] In some embodiments, the material preparation mechanism further includes a non-powered roller assembly, which is disposed at the rear side of the first frame. The non-powered roller assembly includes an upper non-powered roller and a lower non-powered roller, and the raw material passes between the upper non-powered roller and the lower non-powered roller.

[0011] In some embodiments, the cutting mechanism includes a second frame, a feeding section, a feeding roller mechanism, a cutting mechanism, and a pulling mechanism. The feeding section is located on the front side of the second frame, the feeding roller mechanism is located on the rear side of the feeding section, the cutting mechanism is located on the rear side of the feeding roller mechanism, and the pulling mechanism is located on the storage mechanism. The raw material is pulled from the unpowered roller assembly onto the feeding section and enters the feeding roller mechanism, and is then cut by the cutting mechanism under the action of the feeding roller mechanism and the pulling mechanism.

[0012] In some embodiments, bearings are provided on both sides of the second frame, and the feeding roller mechanism includes a first roller group and a second roller group. The first roller group and the second roller group are respectively mounted on the bearings, and the first roller group is located at the rear end of the second frame.

The upper first roller is connected to the first synchronous rack. The raw material is located between the upper second roller and the lower second roller, and between the upper first roller and the lower first roller.

[0034] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0035] like Figures 1 to 12 As shown, this embodiment proposes an automatic material switching device for an automotive headliner production line. The device cuts raw materials and includes a material preparation mechanism 1, a cutting mechanism 2, a storage mechanism 3, and an electrical control system. The material preparation mechanism 1 is located in front of the cutting mechanism 2, and the storage mechanism 3 is located behind the cutting mechanism 2. After the raw material is loaded onto the material preparation mechanism 1, it is pulled onto the cutting mechanism 2 for cutting. After cutting, the raw material is placed in the storage mechanism 3. The material preparation mechanism 1, the cutting mechanism 2, and the storage mechanism 3 are each electrically connected to the electrical control system. The electrical control system controls the material preparation mechanism 1, the cutting mechanism 2, and the storage mechanism 3 respectively, achieving automated operation.

[0036] This utility model proposes an automatic material switching device for an automotive roof production line, which achieves automatic material switching, not only reducing reliance on manpower and lowering production costs, but also solving the problem of continuous machine downtime for manual material changing, thus improving production efficiency.

[0037] Specifically, the material preparation mechanism 1 includes a first frame 11, an electric hoist 12, mounting chucks 13, and air shafts 14. The electric hoist 12 is positioned on the upper side of the first frame 11, and several mounting chucks 13 are positioned on the lower side of the first frame 11. Several air shafts 14 are inserted into the rolled raw materials. The electric hoist 12 lifts the rolled raw materials, and both ends of the air shafts 14 are inserted into the mounting chucks 13, allowing the rolled raw materials to rotate freely between the mounting chucks 13. The raw materials are transmitted from the material preparation mechanism 1 to the cutting mechanism 2. Thus, workers can easily place multiple heavy rolls of raw materials onto the first frame 11. Furthermore, the mounting chucks 13 and air shafts 14 form two sets of feeding rollers, enabling the automatic switching of different raw materials, such as base materials and top layers, on a single machine. Based on current technology, with 10 hours of production per day and a material change interval of 1.5 hours (each change taking 10 minutes), the total downtime is 10 / 1.5 * 10 minutes = 65 minutes. An automatic material changer, on the other hand, reduces downtime for material changes by 1.05 hours per day. With the production line producing one product per minute, it can produce 60 products per hour, representing an estimated 10% increase in efficiency. Therefore, the automatic material changer not only ensures a smoother production line speed but also eliminates the need to stop equipment for material changes, enabling rapid material switching and thus improving production efficiency.

[0038] Preferably, the material preparation mechanism 1 further includes a non-powered roller assembly 15, which is disposed on the rear side of the first frame 11. The non-powered roller assembly 15 includes an upper non-powered roller 151 and a lower non-powered roller 152, through which the raw material passes. The non-powered roller assembly 15 allows different raw materials to be stacked neatly and prevents the already stacked raw materials from scattering during operation.

[0039] Furthermore, the cutting mechanism 2 includes a second frame 21, a feeding section 22, a feeding roller mechanism 4, a cutting mechanism 5, and a pulling mechanism 6. The feeding section 22 is located in front of the second frame 21, the feeding roller mechanism 4 is located behind the feeding section 22, the cutting mechanism 5 is located behind the feeding roller mechanism 4, and the pulling mechanism 6 is located on the storage mechanism 3. The raw material is pulled from the unpowered roller assembly 15 onto the feeding section 22 and enters the feeding roller mechanism 4. Then, under the action of the feeding roller mechanism 4 and the pulling mechanism 6, it is cut by the cutting mechanism 5. Through a series of operations, the stacked raw materials can be cut neatly and accurately.

[0040] Preferably, bearings 23 are provided on both sides of the second frame 21. The feeding roller mechanism 4 includes a first roller group 41 and a second roller group 42. The first roller group 41 and the second roller group 42 are respectively mounted on the bearings 23, and the first roller group 41 is located at the rear end of the second frame 21. The second roller group 42 includes an upper second roller 421 and a lower second roller 422, and is located between the feed section 22 and the first roller group 41. A second synchronous rack 423 is provided on the bearing 23 of the lower second roller 422 to prevent the lower second roller 422 from jamming during movement. The second synchronous rack 423 prevents the second roller group 42 from jamming due to asynchronous forward and backward movement, thereby maintaining smooth movement of the second roller group 42.

[0041] The first roller assembly 41 includes an upper first roller 411 and a lower first roller 412. A first synchronous rack 413 is provided on the bearings 23 of both the upper and lower first rollers 411 and 412. A drive motor 414 is connected to one bearing 23 of the lower first roller 412, driving the lower first roller 412 to rotate. The upper first roller 411 can follow suit. The upper first roller 411 is connected to the first synchronous rack 413. The raw material is located between the upper second roller 421 and the lower second roller 422, and between the upper first roller 411 and the lower first roller 412. The first synchronous rack 413 prevents the first roller assembly 41 from jamming due to asynchronous lifting, lowering, left, and right movements, ensuring smooth operation of the first roller assembly 41.

[0042] Furthermore, the material storage mechanism 3 includes a third frame 31, on which a raw material placement section 32 is provided. Slide rails 33 are respectively provided on the third frame 31 and on both sides of the raw material placement section 32, and the material pulling mechanism 6 is disposed on the slide rails 33. This arrangement allows the material pulling mechanism 6 to pull the raw material onto the raw material placement section 32.

[0043] Preferably, the material pulling mechanism 6 includes a pull rod 61 and material pulling claws 62, with a plurality of material pulling claws 62 disposed on the pull rod 61, and both ends of the pull rod 61 respectively on the slide rail 33. The material pulling claws 62 can move above the raw material placement part 32 through the slide rail 33.

[0044] Furthermore, the cutting mechanism 5 includes a clamping assembly 51 and a cutting blade 52. The clamping assembly 51 includes a pressure plate 511 and a clamping rod 512. After the raw material exits from the first roller group 41, it passes through the cutting mechanism 5 and is then gripped by the pulling claw 62. The pulling claw 62 grips the raw material and slides it on the slide rail 33. Under the action of the first roller group 41 and the pulling claw 62, after the raw material is pulled to a specified length, the clamping rod 512 can drive the pressure plate 511 to press the raw material downwards, and the cutting blade 52 cuts the raw material. This ensures that the raw material is cut to a uniform specification.

[0045] Furthermore, the cut raw material is pulled into the raw material placement section 32 by the pulling gripper 62. The cut raw material is stored in the raw material placement section 32 and then conveyed to the next process.

[0046] Preferably, the raw material can be fiberglass or non-woven fabric. Other materials that are easily cut by the cutting blade 52 can also be used, thereby expanding the application scenarios of the automatic material switching device.

[0047] The working principle is as follows: The worker uses an air shaft 14 to pass through the roll of material (the raw material is purchased in rolls, with a hollow paper drum in the middle whose diameter matches that of the air shaft 14). The air shaft 14 passes through the middle of the paper drum. After the air shaft 14 is aligned with the roll of material, it is inflated. The air shaft 14 can then clamp the inner wall of the paper drum. Then, an electric hoist 12 is used to lift it onto a safety chuck 13. The safety chuck 13 can hold both ends of the air shaft 14 and can rotate freely, thus unpacking the roll of material. The outermost material head is pulled to the feeding roller mechanism 4. Bearings 23 are installed at both ends of each roller of the material roller mechanism 4. The shaft end of the lower first roller 412 is connected to the drive motor 414 to pull one end of the raw material into the space between the upper first roller 411 and the lower first roller 412. The upper first roller 411 descends and presses the raw material, allowing the motor drive 414 to drive the lower first roller 412 to rotate. The upper first roller 411 follows, and the raw material moves forward under the roller drive. After passing the position of the cutter 52, it continues to move forward to the material pulling claw 62. The material pulling claw 62 clamps the front end of the raw material and moves forward. The feeding roller mechanism 4 continuously feeds out the raw material. When it reaches the set length, the material pulling claw 62 and the feeding roller mechanism 4 stop synchronously. The pressure plate 511 above the cutter 52 descends and presses the raw material. The cutter 52 cuts the raw material, the pressure plate 511 resets, and the material pulling claw 62 continues to pull the raw material to the designated position and then returns to the original waiting position for the next material pulling.

[0048] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
