Description

Technical Field

[0001] This invention relates to the field of automotive interior parts technology, specifically to a computer-controlled cutting bed surface lifting device and its lifting method. Background Technology

[0002] Currently, the factory's existing storage racks require frequent manual switching between the outer skin and kraft paper. The outer skin and kraft paper are quite heavy, and the operators frequently have to lift the outer skin, resulting in high labor intensity.

[0003] The outer skin weighs approximately 30 kg, and the kraft paper weighs approximately 25 kg. The original storage rack used two vertical forks fixed to the computer cutting table, 1 meter high. Two operators lifted the outer skin onto the storage rack. After the fabric cutting machine cuts the outer skin, the operators need to remove the outer skin and then place the kraft paper on the storage rack. This process is repeated.

[0004] However, the existing skin support lacks a skin positioning device, causing the skin to move left and right on the support rod, which makes it impossible to effectively cut rectangles of the specified size, resulting in a large amount of skin waste during cutting on the cutting bed. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the above-mentioned technologies by providing a computer cutting bed surface lifting device and its lifting method, which realizes automatic lifting and layering of the surface and kraft paper, and avoids the phenomenon of non-perpendicular cuts when cutting fabric at subsequent workstations, thereby improving the utilization rate of the surface.

[0006] To achieve the above objectives, the computer cutting bed surface lifting device designed in this invention includes a device platform and a rotation lifting device. The device platform is provided with two vertical support rods, and each support rod has a horizontal first support rod at its top. The two first support rods are parallel. The support rod is provided with a second support rod parallel to the first support rod below it. The length of the second support rod is greater than that of the first support rod.

[0007] The rotating lifting device has two triangular curved arms on both sides. The top ends of the two triangular curved arms are respectively hinged to the outer end of a second support rod. The outer end of the triangular curved arm is recessed to form a first V-shaped groove. The inner end of the triangular curved arm is connected to a swing arm cylinder, which drives the triangular curved arm to rotate around the top end.

[0008] The device platform is equipped with a vertical lifting device, which includes two temporary bases located on the outside of the upper second support rod. The temporary bases are provided with a second V-shaped groove and are connected to a lifting cylinder that drives them to move up and down.

[0009] The first support rod has a hinged flap at its end. The flap has a blocking protrusion at the upper part of its outer end and a limiting groove. The first support rod has a limiting post at its end that extends into the limiting groove. The first support rod also has a flap spring at its end that resets the flap.

[0010] The flap is located directly above the second V-shaped groove.

[0011] Preferably, it also includes a rotating rod for fitting the paper tube, wherein both ends of the rotating rod are provided with adjustable limiting rings for limiting the paper tube, and limiting discs are provided on the rotating rod outside the adjustable limiting rings.

[0012] Preferably, both the first and second support rods are provided with a third V-shaped groove for placing the rotating rod.

[0013] Preferably, the first support rod and the second support rod are provided with rolling bearings on both sides of the third V-shaped groove.

[0014] Preferably, the outer ends of the first and second support rods are higher than their inner ends, forming an angle of 2 to 4 degrees with the horizontal plane.

[0015] Preferably, the rotating rod is provided with a scale for adjustment by the adjustable limiting ring.

[0016] A lifting method for the computer cutting bed surface lifting device includes lifting a paper tube wrapped with kraft paper and a paper tube wrapped with a surface layer. Lifting the paper tube wrapped with kraft paper includes the following steps:

[0017] A) Remove the limiting plate and adjustable limiting ring from one end of the rotating rod, pass the rotating rod through the paper tube rolled with kraft paper, lock the adjustable limiting ring against the paper tube, install the limiting plate on the rotating rod, align the limiting plates at both ends with the inner side of the triangular curved arm, and place the rotating rod in the first V-shaped groove.

[0018] B) Activate the swing arm cylinder to rotate the triangular curved arm around the top until the arm on which the rotating rod is placed forms a straight line with the second support rod;

[0019] C) Push the rotating rod so that it enters the second V-shaped groove of the temporary storage base;

[0020] D) Activate the lifting cylinder, and then drive the rotating rod to rise through the temporary storage base, so that the rotating rod pushes the flip plate to rotate upward. The rotating rod continues to rise until the rotating rod separates from the flip plate. At this time, the flip plate spring drives the flip plate to reset, and the temporary storage base drives the rotating rod to fall down, so that the rotating rod falls onto the flip plate and pushes the rotating rod onto the first support rod.

[0021] Lifting a paper roll with a sheath involves the following steps:

[0022] E) Remove the limiting plate and adjustable limiting ring from one end of the rotating rod, pass the rotating rod through the paper tube with the outer skin rolled up, lock the adjustable limiting ring against the paper tube, install the limiting plate on the rotating rod, align the limiting plates at both ends with the inner side of the triangular curved arm, and place the rotating rod in the first V-shaped groove.

[0023] F) Activate the swing arm cylinder to rotate the triangular curved arm around the top until the arm on which the rotating rod is placed forms a straight line with the second support rod, and push the rotating rod onto the second support rod.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. Two manual pneumatic valves are used to control the double-layer independent lifting mechanism. The lifting mechanism drives the outer skin and kraft paper to rise and fall, so as to achieve separate layer storage.

[0026] 2. One end of the rotating rod has a detachable limiting plate and an adjustable limiting ring, which fixes the position of the replaced outer skin and kraft paper to prevent the cut from being non-perpendicular when cutting the fabric in subsequent work stations.

[0027] 3. Place the outer cover and kraft paper in layers in an orderly manner to avoid repeated switching;

[0028] 4. It can quickly switch between different widths of skin, improving the overall skin utilization rate in subsequent cutting processes;

[0029] 5. The operation can be completed by one person, which is simple and reduces the labor intensity of the operator. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] like Figure 1As shown, a computer-controlled cutting bed surface lifting device includes a device platform 1 and a rotating lifting device 2. The device platform 1 has two vertical support rods 3, each with a horizontal first support rod 4 at its top. The two first support rods 4 are parallel. Below the first support rods 4, a second support rod 5, parallel to the first support rods 4, is located on the support rod 3. The length of the second support rod 5 is greater than that of the first support rod 4. The rotating lifting device 2 has two triangular curved arms 6 on both sides. The tops of the two triangular curved arms 6 are respectively hinged to the outer end of a second support rod 5. The outward-facing end of the triangular curved arm 6 is recessed to form a first V-shaped groove 7. The inward-facing end of the triangular curved arm 6 is connected to a swing arm cylinder 8. The swing arm cylinder 8 drives the triangular crank arm 6 to rotate around the top; the device platform 1 is provided with a vertical lifting device 9, which includes two temporary bases 10 located on the outside of the upper second support rod. The temporary base 10 is provided with a second V-shaped groove 11, and the temporary base 10 is connected to a lifting cylinder 12 that drives it to move up and down; the end of the first support rod 4 is hinged with a flap 13, the upper part of the outer end of the flap 13 is provided with a blocking protrusion 14, the flap 13 is provided with a limiting groove 15, the end of the first support rod 4 is provided with a limiting post 16 that extends into the limiting groove 15, and the end of the first support rod 4 is also provided with a flap spring 17 that resets the flap 13; the flap 13 is located directly above the second V-shaped groove 11.

[0037] In addition, it also includes a rotating rod 19 for fitting the paper tube 18. The two ends of the rotating rod 19 are provided with adjustable limiting rings 21 to limit the paper tube 18. Limiting discs 20 are provided on the outside of the adjustable limiting rings 21 on the rotating rod 19.

[0038] In this embodiment, the process includes lifting a paper tube 18 with kraft paper wound on it and a paper tube 18 with a sheath wound on it. Lifting the paper tube 18 with kraft paper wound on it includes the following steps:

[0039] A. Disassemble the limiting plate 20 and adjustable limiting ring 21 at one end of the rotating rod 19, pass the rotating rod 19 through the paper tube 18 wrapped with kraft paper, lock the adjustable limiting ring 21 against the paper tube 18, install the limiting plate 20 on the rotating rod 19, align the limiting plates 20 at both ends with the inner side of the triangular curved arm 6, and place the rotating rod 19 in the first V-shaped groove 7;

[0040] B starts the swing arm cylinder 8, causing the triangular crank arm 6 to rotate around the top until one arm with the rotating rod 19 is placed in a straight line with the second support rod 5;

[0041] C pushes the rotating rod 19, causing it to enter the second V-shaped groove 11 of the temporary storage base 10;

[0042] D starts the lifting cylinder 12, which in turn drives the rotating rod 19 to rise through the temporary base 10. The rotating rod 19 pushes the flap 13 to rotate upward. The rotating rod 19 continues to rise until the rotating rod 19 separates from the flap 13. At this time, the flap spring 17 drives the flap 13 to reset, and the temporary base 10 drives the rotating rod 19 to fall down, so that the rotating rod 19 falls onto the flap 13 and pushes the rotating rod 19 onto the first support rod 4.

[0043] Lifting the paper tube 18 with its outer sheath includes the following steps:

[0044] E. Disassemble the limiting plate 20 and adjustable limiting ring 21 at one end of the rotating rod 19, pass the rotating rod 19 through the paper tube 18 with the outer skin rolled up, lock the adjustable limiting ring 21 against the paper tube 18, install the limiting plate 20 on the rotating rod 19, align the limiting plates 20 at both ends with the inner side of the triangular curved arm 6, and place the rotating rod 19 in the first V-shaped groove 7;

[0045] F starts the swing arm cylinder 8, causing the triangular crank arm 6 to rotate around the top until one arm with the rotating rod 19 is aligned with the second support rod 5, pushing the rotating rod 19 onto the second support rod 5.

[0046] In addition, in this embodiment, both the first support rod 4 and the second support rod 5 are provided with a third V-shaped groove 22 for placing the rotating rod 19, which facilitates the positioning of the rotating rod 19. Furthermore, both the first support rod 4 and the second support rod 5 are provided with rolling bearings 23 on both sides of the third V-shaped groove 22, which facilitates the rotation of the rotating rod 19.

[0047] In other embodiments, the outer ends of the first support rod 4 and the second support rod 5 may be higher than their inner ends, forming an angle of 2 to 4 degrees with the horizontal plane, which facilitates pushing.

[0048] The rotating rod 19 can also be equipped with a scale for adjustment by the adjustable limit ring 21, which is beneficial for precise control of the position of the paper tube 18 on the rotating rod 19.

[0049] This invention relates to a computer-controlled cutting bed surface lifting device and its lifting method. It uses two manual pneumatic valves to control a double-layer independent lifting mechanism. The lifting mechanism drives the surface and kraft paper to rise and fall, achieving separate layered storage. One end of the rotating rod 19 has a detachable limiting plate 20 and an adjustable limiting ring 21, fixing the position of the replaced surface and kraft paper and preventing non-perpendicular cuts during subsequent fabric cutting. Layered and orderly placement of the surface and kraft paper avoids repeated switching. It enables rapid switching between surface widths, improving the overall surface utilization rate in subsequent cutting processes. One person can complete the operation, simplifying the process and reducing the labor intensity of operators.
