Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a quilting assembly, particularly a mattress fabric quilting assembly. Background Technology

[0002] Quilting of mattress fabric is a key process in mattress manufacturing, directly affecting the appearance, feel, and user experience.

[0003] Existing quilting equipment, such as the continuous feeding multi-head quilting equipment and method disclosed in the Chinese Patent Database (application number: 202411405507.5), includes a feeding mechanism, a quilting mechanism, and a control mechanism. The feeding mechanism includes a feeding frame and a feeding roller, with the feeding roller pivotally connected to the feeding frame and used for reciprocating conveying of the material to be processed. The quilting mechanism includes a frame, a conveying assembly, and at least two quilting assemblies. The conveying assembly includes a first driving roller and a first driven roller, both pivotally connected to the frame. The first driving roller and the first driven roller cooperate to reciprocate conveying the material to be processed along the vertical direction of the frame. The first driving roller, the first driven roller, and the feeding roller rotate synchronously to reciprocate conveying the material to be processed. Each quilting assembly includes a needle head and a shuttle head. The shuttle head and the needle head are respectively disposed on both sides of the frame, and the needle head and the shuttle head correspond to the two sides of the material to be processed to sew the material; the needle head and the shuttle head slide synchronously along the lateral side of the frame; each of the quilting components can move independently of each other; the control mechanism is used to control the operation of the feeding mechanism and the quilting mechanism; it also includes a material guiding mechanism, which is installed on the side of the feeding mechanism away from the quilting mechanism. The material guiding mechanism includes a support base, a material bar, a pressure plate base and a material stop base. The material bar is detachably connected to the support base and the material bar passes through the material roll; there are two pressure plates bases and two material stop bases, and they correspond one to one; the two pressure plates bases are respectively inserted into the two ends of the support base, one end of the material stop base slides on the pressure plate base, and the other end is fixed to fix one end of the material roll.

[0004] After the fabric is processed by the aforementioned quilting equipment, it is generally necessary to inspect the appearance quality of the finished fabric, such as skipped stitches, stains, bulges, holes, wrinkles, splices, unfinished edges, and discoloration. In actual use, the above appearance inspections are entirely done manually, which results in low efficiency and inconvenience. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a convenient and efficient mattress fabric quilting assembly.

[0006] The objective of this utility model can be achieved through the following technical solution: a mattress fabric quilting assembly, comprising a quilting machine, a visual inspection mechanism for inspecting the appearance of the finished quilted fabric, and a fabric cutter disposed at the rear of the quilting machine, characterized in that a frame is disposed at the rear of the fabric cutter, and a conveyor belt one and a conveyor belt two are horizontally disposed on the frame, with the conveyor belt one located between the conveyor belt two and the fabric cutter; the aforementioned visual inspection mechanism is disposed directly above the conveyor belt one, and the input end of the conveyor belt one is connected to the output end of the fabric cutter; the conveyor belt two is connected to the output end of the conveyor belt one, and a material gripping mechanism for gripping the finished quilted fabric on the conveyor belt two is disposed at the conveyor belt two, and the visual inspection mechanism is used to control the opening and closing of the material gripping mechanism.

[0007] In use, the finished quilted fabric output from the quilting machine enters the fabric cutting machine, is cut to a set length, and then inputs to conveyor belt 1. After visual inspection by the visual inspection mechanism, it is input to conveyor belt 2. If the visual inspection fails, the finished quilted fabric is directly output from conveyor belt 2. Conversely, if the visual inspection passes, the material grabbing mechanism grabs the finished quilted fabric from conveyor belt 2.

[0008] With the cooperation of a vision inspection mechanism, a material gripping mechanism, and a conveyor belt, the appearance quality of the finished fabric can be automatically detected and the quilted fabric can be automatically delivered to the designated workstation according to the detection structure, realizing machine-to-human operation. It has the advantages of being easy to use, simple, and highly efficient.

[0009] In the aforementioned mattress fabric quilting assembly, the material gripping mechanism is a palletizer, used to stack qualified quilted fabric products vertically for easy subsequent operations.

[0010] As an alternative, in the aforementioned quilted fabric finished product, the material gripping mechanism is a robotic arm.

[0011] In the aforementioned mattress fabric quilting assembly, conveyor belt one is a straight conveyor, and conveyor belt two includes a straight strip section that connects to the output end of conveyor belt one. The conveying directions of the strip section and conveyor belt one are perpendicular. The aforementioned material gripping mechanism is used to grip the finished quilted fabric on the strip section. This design reduces the overall length of the quilting assembly and minimizes space requirements.

[0012] In the aforementioned mattress fabric quilting assembly, the quilting machine includes a material guiding mechanism, which includes a row of material bars distributed front to back. The quilting assembly also includes a second robotic arm and a support. The support has two horizontally rotating rocker arm shafts, which are arranged side by side. Each rocker arm shaft has a long plate fixed on it, and the axes of the long plate, the rocker arm shaft, and the material bars are parallel. The support also has two driving components for driving the two rocker arm shafts to swing. By swinging the rocker arm shafts, a bearing area for supporting the fabric upward can be formed between the two long plates. The second robotic arm is used to grab the fabric and place it horizontally into the bearing area. The support can slide back and forth, and the bearing area can be moved above the material guiding mechanism by sliding the support.

[0013] In use, the second robotic arm grabs the fabric roll from the hopper and places it horizontally into the carrying area. When the fabric roll on one of the material bars is used up and needs to be replaced, the material bar is removed first. Then, the support is moved to move the carrying area to the roll replacement point. Then, the drive unit drives the rocker arm shaft to swing so that the two long plates move away from each other to unload the fabric roll. Finally, the material bar is inserted into the fabric roll and put back in.

[0014] With the cooperation of components such as the robotic arm, drive unit, rocker arm shaft, and long plate, a transfer space is formed above the material guiding mechanism, which effectively reduces the travel distance for operators to change fabric rolls and has the advantages of being convenient and easy to use.

[0015] In the aforementioned mattress fabric quilting assembly, the support frame has a frame structure. Long, horizontally arranged support members are located on both sides of the material guiding mechanism. These support members are fixed in place, and their length extends along the distribution direction of the material rollers. The two ends of the support frame are slidably mounted on the two support members. This design ensures smooth sliding of the support frame and facilitates material roll replacement.

[0016] In the aforementioned mattress fabric quilting assembly, the support component is a floor rail, and each end of the support has at least one roller adapted to the floor rail. This design offers advantages such as simple structure and easy installation.

[0017] In the above-mentioned mattress fabric quilting assembly, the driving component includes a cylinder. The piston rod of the cylinder is connected to the end of the corresponding rocker arm shaft through a fisheye connector. The cylinder body is hinged on the bracket through a rotating shaft, and the axes of the rotating shaft and the material bar are arranged parallel to each other.

[0018] In the aforementioned mattress fabric quilting assembly, each drive component includes two cylinders, which act on the two ends of the corresponding rocker arm shaft to more stably support the material roll and improve working stability.

[0019] Compared with existing technologies, this mattress fabric quilting assembly has the following advantages:

[0020] 1. With the cooperation of a vision inspection mechanism, a material gripping mechanism, and a conveyor belt, the appearance quality of the finished fabric can be automatically detected and the quilted fabric can be automatically delivered to the designated workstation according to the detection structure, realizing machine-to-human operation. It has the advantages of being easy to use, simple, and highly efficient.

[0021] 2. With the cooperation of components such as the robotic arm, drive unit, rocker arm shaft, and long plate, a transfer space is formed above the material guiding mechanism, which effectively reduces the travel distance for operators to change fabric rolls and has the advantages of being convenient and easy to use.

Detailed Implementation

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] Example 1

[0028] This mattress fabric quilting assembly includes a quilting machine 1, a visual inspection mechanism 2 for inspecting the appearance of the finished quilted fabric, and a fabric cutter 3 located behind the quilting machine 1. In the actual product, the quilting machine 1, visual inspection mechanism 2, and fabric cutter 3 are all existing products, and their specific structures will not be described in detail here. The visual inspection mechanism 2 is used to detect defects such as skipped stitches, stains, bulges, holes, wrinkles, splices, unsealed edges, and discoloration.

[0029] Specifically

[0030] A frame 4 is installed behind the fabric cutter 3. A first conveyor belt 5 and a second conveyor belt 6 are horizontally mounted on the frame 4, with the first conveyor belt 5 positioned between the second conveyor belt 6 and the fabric cutter 3. A vision inspection mechanism 2 is located directly above the first conveyor belt 5, and the input end of the first conveyor belt 5 is connected to the output end of the fabric cutter 3. The second conveyor belt 6 is connected to the output end of the first conveyor belt 5, and a material gripping mechanism 7 is installed at the second conveyor belt 6 to grab the finished quilted fabric on the second conveyor belt 6. The vision inspection mechanism 2 is used to control the opening and closing of the material gripping mechanism 7.

[0031] In use, the finished quilted fabric output from the quilting machine 1 enters the fabric cutter 3, is cut to a set length, and then inputs to conveyor belt 5. After visual inspection by the visual inspection mechanism 2, it is input to conveyor belt 6. If the visual inspection fails, the finished quilted fabric is directly output from conveyor belt 6. Conversely, if the visual inspection passes, the material grabbing mechanism 7 grabs the finished quilted fabric on conveyor belt 6.

[0032] With the cooperation of the visual inspection mechanism 2, the material gripping mechanism 7 and the conveyor belt 6, the appearance quality of the finished fabric can be automatically detected and the finished quilted fabric can be automatically sent to the designated work station according to the detection structure, realizing machine-to-human operation, and has the advantages of convenient use, ease and high efficiency.

[0033] In this embodiment,

[0034] Material handling mechanism 7 is a palletizer, used to stack qualified quilted fabric products vertically for easy subsequent operations. The palletizer is an existing product and can be purchased on the market, so it will not be described in detail here.

[0035] Conveyor belt 5 is a straight conveyor, and conveyor belt 6 includes a straight strip section 6a. Strip section 6a connects to the output end of conveyor belt 5, and the conveying directions of strip section 6a and conveyor belt 5 are perpendicular. The material gripping mechanism 7 is used to grip the finished quilted fabric on strip section 6a. This design reduces the overall length of the quilting assembly and minimizes space requirements.

[0036] like Figure 2 and Figure 3As shown, the quilting machine 1 includes a material guiding mechanism 1a, which includes a row of material bars 1b arranged in a front-to-back pattern. The material bars 1b are horizontally positioned, and their axes extend left and right. The quilting assembly also includes a robotic arm 8 and a support 9. The support 9 has two horizontally rotatable rocker arm shafts 10, arranged side-by-side. Each of the two rocker arm shafts 10 has a long plate 11 fixed to it, and the axes of the long plate 11, rocker arm shafts 10, and material bars 1b are parallel. The support 9 also has two driving components for driving the two rocker arm shafts 10 to swing, causing the two long plates 11 to move closer or further apart. By swinging the rocker arm shafts 10, a bearing area 12 for supporting the fabric upwards can be formed between the two long plates 11. The robotic arm 8 is used to grab the fabric and place it horizontally into the bearing area 12. The support 9 can slide back and forth, and by sliding the support 9, the bearing area 12 can be moved above the material guiding mechanism 1a.

[0037] In use, the robotic arm 2 8 grabs the fabric roll from the hopper and places it horizontally into the carrying area 12. When the fabric roll on one of the material bars 1b is used up and needs to be replaced, the material bar 1b is removed first. Then, the support 9 is moved to move the carrying area 12 to the roll replacement position. Then, the drive unit drives the rocker arm shaft 10 to swing so that the two long plates 11 move away from each other to unload the fabric roll. Finally, the material bar 1b is inserted into the fabric roll and put back in.

[0038] With the cooperation of components such as the robotic arm 28, drive unit, rocker arm shaft 10, and long plate 11, a transfer space is formed above the material guiding mechanism 1a, which effectively reduces the travel of operators when changing fabric rolls and has the advantages of being convenient and easy to use.

[0039] In this embodiment,

[0040] The robotic arm 2.8 is an existing structure and can be customized on the market.

[0041] Both ends of the rocker arm shaft 10 are supported on the bracket 9 by bearings to improve the swing stability of the rocker arm shaft 10.

[0042] The support frame 9 has a frame structure. Long, horizontally shaped support members 13 are provided on both sides of the material guiding mechanism 1a. The support members 13 are fixedly installed, and their length extends along the distribution direction of the material bar 1b. The two ends of the support frame 9 are slidably mounted on the two support members 13. This design ensures smooth sliding of the support frame 9 and facilitates material roll replacement. Furthermore, the support members 13 are ground rails, and at least one roller 15 adapted to the ground rail is installed at each end of the support frame 9. This design has advantages such as simple structure and convenient installation.

[0043] The driving component includes a cylinder 14. The piston rod of the cylinder 14 is connected to the end of the corresponding rocker arm shaft 10 via a fisheye joint 16. The cylinder body of the cylinder 14 is hinged to the bracket 9 via a rotating shaft, and the axes of the rotating shaft and the material bar 1b are parallel. Further, each driving component includes two cylinders 14, and the two cylinders 14 act on the two ends of the corresponding rocker arm shaft 10 respectively, to more stably support the material roll and improve working stability.

[0045] The structure and principle of this embodiment are basically the same as those of embodiment one, except that the material gripping mechanism 7 is a robotic arm.

[0046] Example 3

[0047] The structure and principle of this embodiment three are basically the same as those of embodiment one. The difference is that the support member 13 is a linear guide rail, and at least one slider matching the linear guide rail is installed at each end of the bracket 9.
