Description

Technical Field

[0001] This invention relates to the field of fabric spreading machine technology, specifically a functionally decoupled rotary fabric spreading machine. Background Technology

[0002] To address the issue that traditional fabric spreading machines cannot meet the requirements for spreading fabrics with directional requirements, the applicant filed a Chinese utility model patent (CN202222886630.6) on November 1, 2022, for a rotary fabric spreading machine. This machine includes a fabric guiding assembly, a pressing and dispensing assembly, a first moving assembly, and a rotating assembly. The first moving assembly includes a first moving support frame and a first moving drive body. The fabric guiding assembly, pressing and dispensing assembly, and rotating assembly are mounted on the first moving support frame. The rotating assembly includes a rotating support seat and a rotating drive body. The fabric guiding assembly and pressing and dispensing assembly are mounted on the upper surface of the rotating support seat, which is rotatably connected to the upper surface of the first moving support frame. The rotating drive body drives the rotating support seat to rotate. By setting the rotating drive body to drive the rotating support seat, which in turn rotates the fabric guiding assembly and pressing and dispensing assembly, reverse fabric spreading can be performed. However, although this rotary fabric spreading machine can achieve 180° rotation and reversal, it cannot move the fabric laterally, resulting in the inability to adjust the position of the fabric on both sides after rotation.

[0003] In order to achieve lateral movement and facilitate the adjustment of the position of the fabric on both sides, the applicant applied for Chinese utility model patent CN202320830298.3 on April 14, 2023, for a stable rotating lateral movement device. The device is equipped with a rotating support frame including a middle frame and an upper frame, and a reciprocating motion mechanism is set between the upper frame and the middle frame. However, because the pressing and feeding component (i.e. the feeding wheel component) is set on the middle frame, the feeding wheel component cannot move laterally when the upper frame moves the fabric laterally, which causes the fabric to wrinkle during lateral movement.

[0004] To address the problem of fabric wrinkling during lateral movement, the applicant filed a Chinese invention patent (CN202310900388.X) on November 28, 2023, for a rotary fabric spreading machine to prevent fabric wrinkling. The machine includes a main support frame, a rotating assembly, a rotating fabric hopper, a lifting assembly, a fabric feeding wheel assembly, and a lateral movement assembly. The bottom of the rotating fabric hopper is connected to the rotating assembly. The fabric feeding wheel assembly is connected to the rotating fabric hopper via the lifting assembly, which drives the assembly to move up and down. The lateral movement assembly is positioned between the main support frame and the rotating assembly, and drives the rotating fabric hopper and the fabric feeding wheel assembly to rotate together via the rotating assembly. The lateral movement assembly also drives the rotating assembly, the rotating fabric hopper, and the fabric feeding wheel assembly to move laterally together. However, the above-mentioned rotary fabric spreading machine still has the following problems in actual use: Due to the need for correction, the cutting component moves laterally along with the fabric feeding wheel assembly. After the cutting component cuts the fabric, the fabric may adhere to the cutting component, causing the fabric subsequently released by the fabric feeding wheel assembly to not fall down normally. In addition, in some cases, it may be necessary to fold the fabric back and forth, so a fabric gripping component or fabric folding device may also be provided on the output side of the cutting component. When the fabric gripping component or fabric folding device acts on the fabric, if the cutting component moves laterally along with the fabric feeding wheel assembly, the fabric may still be prone to wrinkles. In addition, the fabric correction mechanism (i.e., the fabric edge correction mechanism) is set on the main support frame, and the correction function can only be achieved by illuminating the edge of the fabric from the back of the fabric, which limits the scope of use of the fabric correction mechanism. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a functionally decoupled rotary fabric spreading machine, which solves the problem that existing rotary fabric spreading machines are still prone to fabric wrinkling during actual fabric spreading, and the application range of the fabric correction mechanism is limited.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A functionally decoupled rotary fabric spreading machine includes a main unit, a fabric bucket assembly, a fabric feeding wheel assembly, a cutting assembly, a first support member, a second support member, and a lifting assembly;

[0008] The main unit includes a frame, a translation component, and a rotation component. The translation component is located between the frame and the rotation component, and the rotation component is connected to the fabric hopper component. Both ends of the fabric feeding wheel component are connected to first support members. Each first support member is connected to the fabric hopper component through a lifting component. A second support member is provided below each first support member. The bottom of the first support member is slidably connected to the second support member. Both ends of the cutting component are supported on the second support members. Each second support member is provided with a limiting component for contacting the inner side of the frame and the fabric hopper component to achieve a limiting position.

[0009] Furthermore, it also includes a fabric correction mechanism;

[0010] The fabric correction mechanism includes a support rod located above the cutting assembly, a detection assembly located on the support rod, and a connector. A fabric passage is formed between the support rod and the fabric feeding wheel assembly, and the detection end of the detection assembly faces the fabric passage. Both ends of the support rod are connected to a second support member through the connector.

[0011] Furthermore, the frame includes a connecting frame and first support main plates disposed at both ends of the connecting frame; the hopper assembly has second support main plates on both sides; the limiting assembly includes at least two limiting rollers distributed vertically, each limiting roller being rotatably connected to a second support member via a connecting shaft; when the lifting assembly drives the first and second support members to descend to their positions, each limiting roller is in rolling contact with the inner surface of the first support main plate; when the lifting assembly drives the first and second support members to rise to their positions, each limiting roller is in rolling contact with the inner surface of the second support main plate; at any moment during the lifting assembly's lifting movement of the first and second support members, at least one limiting roller is in rolling contact with the inner surface of either the first or second support main plate.

[0012] Furthermore, a horizontal support plate is formed in the middle of each of the second support members along the horizontal direction, and a support beam is provided between the bottoms of the two first support members; at least two first guide rails are provided at the bottom of both ends of the support beam along the length direction, and at least one first slider is provided on the top of the horizontal support plate corresponding to each first guide rail, and the first slider is slidably connected to the first guide rail.

[0013] Furthermore, each of the lifting components includes a lifting support plate, a lifting rack, a first drive motor, a first drive gear, a second guide rail, and a second slider; the lower end of the lifting support plate is connected to the first support member, the lifting rack is vertically mounted on the lifting support plate, the first drive motor is mounted on the hopper assembly, the first drive gear is connected to the output end of the first drive motor, and the first drive gear meshes with the lifting rack; the second slider is slidably connected to the second guide rail, and the lifting support plate is connected to the hopper assembly through the second slider and the second guide rail.

[0014] Furthermore, it also includes a synchronous shaft; the first drive gears of the two lifting components are connected through the synchronous shaft, and the two lifting components share a first drive motor.

[0015] Furthermore, the translation component includes a second drive motor, a second drive gear, a horizontal rack, a third guide rail, and a third slider; the horizontal rack is located at the bottom of the rotating component, the second drive motor is located on the frame, the second drive gear is connected to the output end of the second drive motor, and the second drive gear meshes with the horizontal rack; the third slider is slidably connected to the third guide rail, and both sides of the bottom of the rotating component are connected to the frame through the third slider and the third guide rail.

[0016] Furthermore, the rotating assembly includes a main support plate, a rotary gear disk, a third drive gear, and a third drive motor; the rotary gear disk has an inner bearing ring for connecting with the main support plate and an outer bearing ring for connecting with the cloth bucket assembly; the third drive motor is mounted on the main support plate; the third drive gear is connected to the output end of the third drive motor; and the third drive gear meshes with the outer bearing ring.

[0017] Furthermore, the detection component is a color mark sensor, a vision component, or a photoelectric sensor.

[0018] Furthermore, the output side of the cutting component is also equipped with a fabric gripping component or a fabric folding device.

[0019] By adopting the above-described technical solution of the present invention, at least the following beneficial effects are achieved:

[0020] 1. The rotary fabric spreading machine is designed to include a first support and a second support, with the bottom of the first support slidably connected to the second support. Both ends of the fabric feeding wheel assembly are connected to the first support, and both ends of the cutting assembly are supported on the second support. A limiting component is provided on the second support to achieve a limiting function. This allows for several adjustments during use. Firstly, when rotational reversal is required, the lifting assembly can be used to raise the fabric feeding wheel assembly, cutting assembly, first support, and second support to the desired position. Then, the rotary assembly can be used to move the fabric hopper assembly, lifting assembly, fabric feeding wheel assembly, first support, second support, and cutting assembly together. After rotating 180°, the lifting component drives the fabric feeding wheel assembly, cutting component, first support component, and second support component to descend to the desired position, thereby realizing the rotation reversal function. On the other hand, when the translation component drives the rotation component, fabric bucket assembly, lifting component, fabric feeding wheel assembly, and first support component to move laterally together, the second support component and cutting component will not move laterally with the fabric feeding wheel assembly due to the limiting effect of the limiting component. This decouples the fabric feeding wheel assembly and the cutting component, which can effectively solve the problem of fabric wrinkles that easily occur in the actual fabric laying process of existing rotary fabric laying machines, and can ensure the fabric laying effect of the rotary fabric laying machine.

[0021] 2. The fabric correction mechanism is designed with a support rod above the cutting assembly, a detection component on the support rod, and a connector between the support rod and the second support member. A fabric passage is formed between the support rod and the fabric feeding wheel assembly, with the detection end of the detection component facing the passage. This allows the detection component to detect the fabric from the front, facilitating the configuration of different detection components based on actual needs. For example, the detection component can be a color mark sensor to detect inner alignment stripes, or a vision component to identify inner alignment stripes, the front and back of the fabric, etc. Therefore, it can effectively meet the correction needs of various scenarios, expanding the scope and flexibility of application beyond simply detecting the edge of the fabric. Furthermore, both ends of the support rod are connected to the second support member via connectors, decoupling the detection component from the fabric feeding wheel assembly for easier correction. Additionally, the overall fabric correction mechanism is simpler, reducing overall implementation costs. Attached Figure Description

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see the appendix Figures 1 to 7As shown, this invention provides a functionally decoupled rotary fabric spreading machine 100. The rotary fabric spreading machine 100 includes a main unit 1, a fabric hopper assembly 2, a fabric feeding wheel assembly 3, a cutting assembly 4, a first support member 5, a second support member 6, and a lifting assembly 7. The main unit 1 is used to meet the support requirements of each component and to drive the fabric hopper assembly 2 to rotate and move laterally. The fabric hopper assembly 2 is used to hold rolled fabric. The fabric feeding wheel assembly 3 is used to feed the fabric. The cutting assembly 4 is used to cut the fabric. The first support member 5 is used to support the fabric feeding wheel assembly 3. The second support member 6 is used to support the cutting assembly 4. The lifting assembly 7 is used to drive the fabric feeding wheel assembly 3, the cutting assembly 4, the first support member 5, and the second support member 6 to move up and down together. It should be noted that the fabric hopper assembly 2, the fabric feeding wheel assembly 3, and the cutting assembly 4 are all conventional components that are required in existing rotary fabric spreading machines 100; therefore, this invention will not provide a detailed description of the fabric hopper assembly 2, the fabric feeding wheel assembly 3, and the cutting assembly 4 thereafter.

[0042] The main unit 1 includes a frame 11, a translation component 12, and a rotation component 13. The translation component 12 is located between the frame 11 and the rotation component 13. The rotation component 13 is connected to the fabric hopper component 2. During operation, the translation component 12 can drive the rotation component 13, the fabric hopper component 2, the lifting component 7, the fabric feeding wheel component 3, and the first support member 5 to move laterally together. The rotation component 13 can drive the fabric hopper component 2, the lifting component 7, the fabric feeding wheel component 3, the first support member 5, the second support member 6, and the cutting component 4 to rotate 180° together. Both ends of the fabric feeding wheel component 3 are connected to the first support member 5, and each first support member 5 is connected to a lifting component. 7 is connected to the cloth bucket assembly 2. Each first support member 5 is provided with a second support member 6 below it. The bottom of the first support member 5 is slidably connected to the second support member 6, so that the first support member 5 can move laterally relative to the second support member 6. The two ends of the cutting assembly 4 are supported on the second support member 6. Each second support member 6 is provided with a limiting component 61 for contacting the inner side of the frame 11 and the cloth bucket assembly 2 to achieve a limiting position. Through the limiting function of the limiting component 61, on the one hand, the second support member 6 can be prevented from moving laterally with the first support member 5, and on the other hand, it can be ensured that the second support member 6 and the cutting assembly 4 will not be thrown out during rotation.

[0043] This invention designs a rotary fabric spreading machine 100 including a first support member 5 and a second support member 6, with the bottom of the first support member 5 slidably connected to the second support member 6. The two ends of the fabric spreading wheel assembly 3 are connected to the first support member 5, and the two ends of the cutting assembly 4 are supported on the second support member 6. Simultaneously, the second support member 6 is provided with a limiting component 61 for limiting the movement. This allows for efficient operation during use. When rotational reversal is required, the lifting assembly 7 can be used to raise the fabric spreading wheel assembly 3, the cutting assembly 4, the first support member 5, and the second support member 6 to the desired position. Then, the rotating assembly 13 can be used to move the fabric hopper assembly 2, the lifting assembly 7, the fabric spreading wheel assembly 3, the first support member 5, the second support member 6, and the cutting assembly 4 together. The components rotate 180° together, and finally, the lifting component 7 drives the fabric feeding wheel component 3, the cutting component 4, the first support component 5, and the second support component 6 to descend to the required position, thereby realizing the rotation reversal function. On the other hand, when the translation component 12 drives the rotation component 13, the fabric bucket component 2, the lifting component 7, the fabric feeding wheel component 3, and the first support component 5 to move laterally together, the second support component 6 and the cutting component 4 will not move laterally with the fabric feeding wheel component 3 due to the limiting effect of the limiting component 61. This decouples the fabric feeding wheel component 3 from the cutting component 4, which can effectively solve the problem of fabric wrinkles that easily occur in the actual fabric laying process of existing rotary fabric laying machines, and can ensure the fabric laying effect of the rotary fabric laying machine.

[0044] Please refer to the following in some embodiments of the present invention. Figure 6 As shown, the rotary fabric spreading machine 100 also includes a fabric correction mechanism 8;

[0045] The fabric correction mechanism 8 includes a support rod 81 positioned above the cutting assembly 4, a detection assembly 82 mounted on the support rod 81, and a connecting member 83. A fabric passage 9 is formed between the support rod 81 and the fabric feeding wheel assembly 3. The detection end of the detection assembly 82 faces the fabric passage 9, enabling the detection assembly 82 to detect the front side of the fabric. Both ends of the support rod 81 are connected to a second support member 6 via the connecting member 83, so that the second support member 6 can meet the support requirements of the fabric correction mechanism 8. In specific implementations of this invention, one or more detection assemblies 82 can be installed on the support rod 81 according to actual usage needs.

[0046] In actual use of the rotary fabric spreading machine 100, the fabric surface may be printed, or the fabric may be a composite fabric. These fabrics require alignment of the inner alignment stripes near the edge, not the edge itself. This makes existing fabric correction mechanisms inadequate for some special scenarios. Therefore, this invention designs a fabric correction mechanism 8 including a support rod 81 above the cutting assembly 4, a detection component 82 on the support rod 81, and a connector 83 connecting the support rod 81 and the second support member 6. A fabric passage channel 9 is formed between the support rod 81 and the fabric feeding wheel assembly 3, with the detection end of the detection component 82 facing the fabric passage channel 9. This allows the detection component 82 to detect the fabric from the front during use. This also allows for the convenient configuration of different detection components 82 according to actual needs; for example, the detection component 82 can be a color mark sensor to detect the inner alignment stripes. Alternatively, the detection component 82 can be configured as a vision component to identify inner alignment stripes, the front and back of the fabric, etc. Therefore, it can well meet the correction needs of various scenarios, so that the fabric correction mechanism 8 is no longer limited to detecting the edge position of the fabric to achieve correction, thereby improving the scope of use and flexibility of use. At the same time, both ends of the support rod 81 are connected to the second support member 6 through the connector 83. This design also decouples the detection component 82 from the fabric feeding wheel assembly 3, thereby facilitating the actual correction operation. In addition, the entire fabric correction mechanism 8 is also simpler, which helps to reduce the overall implementation cost.

[0047] In some embodiments of the present invention, the detection component 82 is a color mark sensor or a vision component. In specific implementations, either color mark sensors or vision components can be installed at both ends of the support rod 81. When the detection component 82 is a color mark sensor, it can be used to detect the inner alignment stripes on the fabric to achieve a correction function. When the detection component 82 is a vision component, it can be used to identify the inner alignment stripes of the fabric, the front and back of the fabric, etc. Furthermore, during actual use, when the detection component 82 detects a fabric offset, it can trigger an alarm to control the fabric feeding wheel assembly 3 for correction. Of course, the above are only some specific embodiments of the present invention, but the present invention is not limited to these. In specific implementations, other sensors can be used to replace the color mark sensor, as long as they can detect the fabric offset to achieve the correction function. For example, the detection component 82 can also be a photoelectric sensor to detect the edge position of the fabric, thereby achieving the correction function.

[0048] In some embodiments of the present invention, the frame 11 includes a connecting frame 111 and a first support main plate 112 disposed at both ends of the connecting frame 111; the cloth bucket assembly 2 has second support main plates 21 on both sides; the limiting assembly 61 includes at least two limiting rollers 611 distributed vertically, each limiting roller 611 being rotatably connected to the second support member 6 via a connecting shaft 612; when the lifting assembly 7 drives the first support member 5 and the second support member 6 to descend to their positions, each limiting roller 611 makes rolling contact with the inner surface of the first support main plate 112, so as to limit the second support member 6 using the first support main plate 112; when the lifting assembly 7 drives the first support member 5 and the second support member 6 to rise to their positions, each limiting roller 611 makes rolling contact with the inner surface of the second support main plate 21. The inner surface of the first support 5 and the second support 6 are in rolling contact, so as to limit the second support 6 by using the second support main board 21. At any moment when the lifting component 7 drives the first support 5 and the second support 6 to move up and down, at least one limiting roller 611 is in rolling contact with the inner surface of the first support main board 112 or the second support main board 21. Since the cloth bucket component 2 can rotate and change direction relative to the host 1, a gap needs to be left between the cloth bucket component 2 and the host 1. If all the limiting rollers 611 are in the gap during the lifting process, the second support 6 may be deflected. Therefore, by adopting the above structural design, it can be effectively ensured that the second support 6 can be limited at any time, so that the second support 6 can only move up and down and cannot move laterally.

[0049] To enable the fabric hopper assembly 2, lifting assembly 7, fabric feeding wheel assembly 3, first support member 5, second support member 6, and cutting assembly 4 to rotate together for reversal, the fabric feeding wheel assembly 3, cutting assembly 4, first support member 5, and second support member 6 need to be able to rise and fall together under the drive of the lifting assembly 7. To this end, the present invention designs a limiting assembly 61 including at least two limiting rollers 611 for rolling contact with the inner surfaces of the first support main plate 112 and the second support main plate 21. This design allows the second support member 6 to move up and down easily to achieve the rotational reversal function, while ensuring that when the lifting assembly 7 drives the fabric feeding wheel assembly 3, cutting assembly 4, first support member 5, and second support member 6 to rise and fall together, the second support member 6 is always limited by the first support main plate 112 or the second support main plate 21. This ensures that the second support member 6 can only rise and fall and cannot move laterally. In particular, it ensures that the second support member 6 and the cutting assembly 4 will not move laterally along with the fabric feeding wheel assembly 3 under the action of the translation assembly 12.

[0050] In some embodiments of the present invention, to ensure the stability of the fabric feeding wheel assembly 3 during lateral movement, a horizontal support plate 62 is formed in the middle of each second support member 6 along the horizontal direction, and a support beam 51 is provided between the bottoms of the two first support members 5; at least two first guide rails 52 are provided along the length direction at the bottom of both ends of the support beam 51, and at least one first slider 63 is provided at the top of the horizontal support plate 62 corresponding to each first guide rail 52, and the first slider 63 is slidably connected to the first guide rail 52. As a specific embodiment of the present invention, two first guide rails 52 are provided along the length direction at the bottom of both ends of the support beam 51, and a first slider 63 is provided at the top of the horizontal support plate 62 corresponding to each first guide rail 52.

[0051] Please refer to the following in some embodiments of the present invention. Figure 3 , Figure 6 and Figure 7 As shown, each of the lifting components 7 includes a lifting support plate 71, a lifting rack 72, a first drive motor 73, a first drive gear 74, a second guide rail 75, and a second slider 76. The lower end of the lifting support plate 71 is connected to the first support member 5. The lifting rack 72 is arranged vertically on the lifting support plate 71. The first drive motor 73 is arranged on the hopper assembly 2. The first drive gear 74 is connected to the output end of the first drive motor 73 and meshes with the lifting rack 72. The second slider 76 is slidably connected to the second guide rail 75. The lifting support plate 71 is connected to the hopper assembly 2 through the second slider 76 and the second guide rail 75. In specific operation, the lifting assembly 7 of the present invention is driven by the first drive motor 73 to rotate the first drive gear 74. During the rotation, the first drive gear 74 can drive the lifting rack 72 and the lifting support plate 71 to rise and fall, thereby driving the cloth feeding wheel assembly 3, the cutting assembly 4, the first support member 5 and the second support member 6 to rise and fall together. At the same time, by setting the second slider 76 and the second guide rail 75 between the lifting support plate 71 and the cloth bucket assembly 2, the stability of the lifting process can be ensured.

[0052] In one specific embodiment of the present invention, the lifting assembly 7 further includes a synchronous shaft 77; the first drive gears 74 of the two lifting assemblies 7 are connected through the synchronous shaft 77, and the two lifting assemblies 7 share a first drive motor 73. By adopting the above structural design, on the one hand, the synchronicity of the two ends of the fabric feeding wheel assembly 3 and the cutting assembly 4 during lifting can be ensured; on the other hand, only one first drive motor 73 is needed for the two lifting assemblies 7, which can reduce the implementation cost.

[0053] Please refer to the following in some embodiments of the present invention. Figure 4 and Figure 5As shown, the translation component 12 includes a second drive motor 121, a second drive gear 122, a horizontal rack 123, a third guide rail 124, and a third slider 125. The horizontal rack 123 is located at the bottom of the rotation component 13. The second drive motor 121 is located on the frame 11. The second drive gear 122 is connected to the output end of the second drive motor 121 and meshes with the horizontal rack 123. The third slider 125 is slidably connected to the third guide rail 124. Both sides of the bottom of the rotation component 13 are connected to the frame 11 through the third slider 125 and the third guide rail 124. In actual operation, the translation component 12 of the present invention is driven by the second drive motor 121 to rotate the second drive gear 122. During the rotation, the second drive gear 122 can drive the horizontal rack 123 and the rotating component 13 to move laterally together, thereby driving the cloth bucket component 2, the lifting component 7, the cloth feeding wheel component 3 and the first support member 5 to move laterally together. However, the second support member 6 and the cutting component 4 are restricted and will not move laterally together. At the same time, by setting the third slider 125 and the third guide rail 124 between the bottom sides of the rotating component 13 and the frame 11, the stability during lateral movement can be ensured.

[0054] Please refer to the following in some embodiments of the present invention. Figure 4 As shown, the rotating assembly 13 includes a main support plate 131, a rotary gear disk 132, a third drive gear 133, and a third drive motor 134. The rotary gear disk 132 has an inner bearing ring 1321 for connecting to the main support plate 131 and an outer bearing ring 1322 for connecting to the cloth bucket assembly 2. The third drive motor 134 is mounted on the main support plate 131 so that the main support plate 131 can support the third drive motor 134. The third drive gear 133 is connected to the output end of the third drive motor 134 and meshes with the outer bearing ring 1322. In specific operation, the rotating component 13 of the present invention is driven by the third drive motor 134 to rotate the third drive gear 133. When the third drive gear 133 rotates, it can drive the outer gear ring 1322 of the bearing to rotate. Since the cloth bucket component 2 is connected to the outer gear ring 1322 of the bearing, it can drive the cloth bucket component 2, the lifting component 7, the cloth feeding wheel component 3, the first support member 5, the second support member 6 and the cutting component 4 to rotate 180° together to achieve reversal.

[0055] In some embodiments of the present invention, the output side of the cutting component 4 is also equipped with a fabric gripping component or a fabric folding device (not shown). Specifically, the fabric gripping component or fabric folding device can be connected to the cutting component 4. The fabric gripping component or fabric folding device are common components of existing fabric spreading machines, and their specific structures and working principles are well known to those skilled in the art. Therefore, the fabric gripping component or fabric folding device will be described in detail here.
