Description

Technical Field

[0001] This utility model relates to the field of absorbent material production equipment, and in particular to an automatic feed tape peeling device for absorbent material production. Background Technology

[0002] Absorbent products are a class of products whose core function is to absorb and contain liquids or semi-fluids (such as human body fluids, secretions, excretions, etc.), and they are widely used in personal hygiene, maternal and infant care, medical care, and daily household scenarios.

[0003] The final product needs to be made from multiple sets of semi-finished products of different materials through processes such as compounding, molding, and cutting on the main line. Each set of semi-finished products of different materials needs to be made from at least three different raw materials through processes such as feeding, gripping, pulling, and peeling. Each raw material is made up of multiple rolls of material stacked together. Each roll of material is covered with tape, and the release paper of the tape is located on the outside of the roll of material. In the existing technology, all of the above actions are done manually, which is inefficient and has high labor costs. Moreover, the material is easily damaged during the pulling and peeling of the tape, and the production quality of the semi-finished products and the final product cannot be guaranteed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic feeding tape peeling device for the production of absorbent materials that can achieve uninterrupted feeding, full-process automation, high-precision peeling, and high production efficiency.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An automatic feed tape peeling device for the production of absorbent articles includes

[0007] A material feeding and transpositioning mechanism, comprising a horizontal conveying unit and at least three trays, wherein the horizontal conveying unit is provided with at least three material stations, and each material station is provided with one tray, the tray being used to place multiple materials to be pulled.

[0008] The main production line is located on one side of the horizontal conveying unit. The main production line includes a main feeding area, a tape peeling area, and a negative pressure suction plate. The negative pressure suction plate is located on one side of the tape peeling area and is used to adsorb and fix the material after traction.

[0009] An automatic material feeding and tape peeling fixture includes a picking component, a feeding component, a feeding component, and a tape peeling component. The picking component picks up a piece of material to be pulled from the tray. The feeding component places the material to be pulled into the main unit's loading area. The feeding component pulls the material to be pulled to the tape peeling area. The tape peeling component peels the tape off the material.

[0010] A robotic arm, connected to the automatic feeding tape peeling fixture, is used to drive the automatic feeding tape peeling fixture to move between the horizontal conveyor unit and the main production line.

[0011] Furthermore, the material handling assembly includes a clamp body, a clamp body air expansion shaft, a sliding shaft, and a linear bearing seat. The linear bearing seat is mounted on the clamp body, the sliding shaft is slidably mounted on the linear bearing seat, and the clamp body air expansion shaft is sleeved outside the sliding shaft for extending into the core of the material to be pulled, so as to tighten and handle the material.

[0012] Furthermore, the feeding assembly includes a servo electric cylinder, a connecting plate, and a pusher plate.

[0013] Furthermore, the material feeding assembly includes a negative pressure adsorption body and a contact plate. The negative pressure adsorption body is mounted on the clamp body and has a vacuum chamber. The contact plate covers the bottom of the vacuum chamber and is used to adhere the release paper of the adhesive tape. The contact plate has a plurality of suction cup holes evenly distributed on it. The suction cup holes are connected to the vacuum chamber and are used to transfer the negative pressure of the vacuum chamber to the surface of the release paper, thereby adsorbing the release paper.

[0014] Furthermore, the tape peeling assembly includes a cylinder and peeling grippers. The cylinder is mounted on the negative pressure adsorption body. One end of the peeling gripper is hinged to the output shaft of the cylinder, and the other end is hinged to the negative pressure adsorption body.

[0016] Furthermore, the feeding and switching mechanism also includes a feeding conveying unit and a lifting conveying unit. The feeding conveying unit has a material starting station for conveying the pallet. The horizontal conveying unit also has two switching empty stations. The material stations are continuously arranged, and the number of material stations is equal to the number of pallets. The material station includes a target material station. The two switching empty stations are located on both sides of the material station. The lifting conveying unit is connected to the feeding conveying unit and extends to the target material station. It is used to lift the pallets sequentially to the same height as the horizontal conveying unit and convey them to the target material station. It also lowers the empty pallets on the target material station to the same height as the feeding conveying unit and returns them to the material starting station. The horizontal conveying unit places the pallets on the corresponding material stations through the switching empty stations and conveys the empty pallets to the target material station.

[0017] Furthermore, the lifting and conveying unit includes a base, a lifting drive assembly, and a base plate assembly. The lifting drive assembly includes multiple linear bearings and multiple sliding shafts. The base plate assembly includes two base plates, two conveyor belts, and a central cross brace. The multiple linear bearings are vertically mounted on the base, and each sliding shaft is slidably mounted on one of the linear bearings. The two base plates are arranged relatively parallel to each other.

Multiple feeding and switching areas are arranged inside the capsule along the extension direction of the internal channel. Each feed inlet is directly opposite a feeding and switching area. Each feeding and switching area is equipped with a horizontal conveying unit. Each robotic arm is positioned between a horizontal conveying unit and the main production line. Each automatic feeding tape peeling fixture is located at the end of a robotic arm. The discharge port is located on the side of the capsule for outputting the final finished hygiene product.

[0020] Compared with existing technologies, the automatic feed tape peeling device for the production of absorbent articles of this invention has the following advantages:

[0021] (1) This application can realize the cyclic feeding from material loading and changing, grabbing, transferring, traction to tape peeling, and can realize uninterrupted feeding and full-process automation, improve equipment utilization and production efficiency, and ensure the production quality of semi-finished products and final products.

[0022] (2) This application integrates multiple processes of "material picking-feeding-guiding-stripping" into the same fixture device, realizing no manual intervention in the whole process and coordinated control of parameters of each process, so as to solve the core problems such as low connection efficiency, large positioning error and poor coordination of manual operation or decentralized equipment, and improve production efficiency.

[0023] (3) This application divides the vacuum chamber inside the adsorption body into three independent sections, and opens the vacuum system of the corresponding section as needed, so that the suction cup hole of the section generates negative pressure. By using the "internal and external air pressure difference", materials of different widths are firmly adsorbed onto the contact plate, so as to achieve flexible adaptation and stable adsorption of "narrow, medium and wide" materials.

[0024] (4) This application, through the cooperation of at least three pallets and continuous material stations, allows the loading pallets to be transported sequentially to each material station to supply materials to the production line, while empty pallets are returned through the target material station. The entire process does not require machine downtime, thus completely eliminating the production idle period. This application sets up an independent empty station for pallet exchange. When pallets are exchanged, their positions are adjusted through the empty station before entering the target material station, avoiding direct collisions or offsets between multiple pallets and greatly reducing the risk of material jamming.

[0025] (5) Due to the wide variety of material specifications in the main line, this application designs a corresponding pallet structure, namely, a pallet for vertical material placement and a pallet for horizontal material placement. The pallet can be adjusted arbitrarily according to different sizes and widths, which is highly compatible and greatly improves applicability.

[0026] (6) This application integrates all the mechanisms into a closed space capsule. The space capsule adopts a modular structure design. The two ends use a unified module that remains unchanged, while the middle unit is added in groups. Moreover, the modular structure facilitates assembly and maintenance, adapts to existing production processes, and ensures design quality while controlling manufacturing costs and improving production efficiency during the material and manufacturing process.

[0065] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0066] Figures 1-18 The present invention relates to an automatic feeding tape peeling device for the production of absorbent articles, comprising a feeding and switching mechanism 20, an automatic feeding tape peeling fixture 30, a main production line 40, and a robotic arm 50.

[0067] In this embodiment:

[0068] like Figure 1-2 As shown, the space capsule 10 is equipped with a feed inlet, an internal channel 11, a feeding and switching area, and a discharge outlet. The feeding and switching area is located inside the internal channel 11. The feed inlet is connected to the discharge outlet through the internal channel 11. The horizontal conveying unit 23 is located inside the feeding and switching area. The main production line 40 is set inside the internal channel 11 and is located on one side of the feeding and switching mechanism 20. The robotic arm 50 is located between the feeding and switching mechanism 20 and the main production line 40.

[0069] The space capsule 10 in this application adopts a modular structure design. The two ends use a unified module that remains unchanged, while the middle unit is added in groups. Moreover, the modular structure facilitates assembly and maintenance, adapts to existing production processes, and ensures design quality while controlling manufacturing costs and improving production efficiency in the use of materials and manufacturing process.

[0070] like Figure 4-9 As shown, the feeding and transposition mechanism 20 includes a feeding conveying unit 21, a lifting conveying unit 22, a horizontal conveying unit 23, and at least three pallets.

[0071] The material feeding and conveying unit 21 is equipped with a material starting station 211 for conveying pallets, which are used to place sanitary products materials.

[0072] The horizontal conveying unit 23 has multiple material stations and two empty interchange stations. The material stations are arranged continuously, and the number of material stations is equal to the number of pallets. The material stations include the target material station 232, and the two empty interchange stations are located on both sides of the material stations. In this embodiment, the length direction of the horizontal conveying unit 23 is perpendicular to the length direction of the feeding conveying unit 21.

[0073] The lifting conveyor unit 22 is connected to the feeding conveyor unit 21 and extends to the target material station 232. On one hand, it sequentially lifts the pallets to a height level with the horizontal conveyor unit 23 and conveys them to the target material station 232. On the other hand, it lowers the empty pallets on the target material station 232 to a height level with the feeding conveyor unit 21 and returns them to the material starting station 211. The horizontal conveyor unit 23 places the pallets on the corresponding material stations by switching empty stations and sequentially conveys the empty pallets to the target material station 232. In this embodiment, the horizontal conveyor unit 23 is a chain conveyor, a synchronous belt conveyor, or a roller conveyor.

[0074] In this embodiment, there are three pallets and material stations. The horizontal conveying unit 23 is provided with a first vacant exchange station 234, a first material station 231, a target material station 232, a second material station 233, and a second vacant exchange station 235 along its length.

[0075] The lifting conveying unit 22 is used to convey a pallet to the target material station 232 and to return an empty pallet on the target material station 232 to the material origin station 211. The horizontal conveying unit 23 moves in a first direction to move the pallet on the target material station 232 to the second empty station 235. The horizontal conveying unit 23 moves in a second direction to move the pallet on the target material station 232 to the first material station 231. At this time, the pallet on the original second empty station 235 is conveyed to the second material station 233. The horizontal conveying unit 23 moves in a first direction to move the pallet on the first material station 231 to the target material station 232. The horizontal conveying unit 23 moves in a second direction to move the pallet on the second material station 233 to the target material station 232. At this time, the pallet on the original first material station 231 is conveyed to the first empty station 234. The first direction and the second direction are opposite.

[0076] The lifting and conveying unit 22 includes a base 223, a lifting drive assembly 221, and a base plate assembly 222.

[0077] The lifting drive assembly 221 includes multiple linear bearings 2211 and multiple sliding shafts 2212. The multiple linear bearings 2211 are vertically mounted on the base 223, and each sliding shaft 2212 is slidably mounted on a linear bearing 2211. Two base plates 2221 are arranged relatively parallel to each other, and a cross brace 2222 is installed between the two base plates 2221 with its two ends fixedly connected to the base plates 2221 respectively.

[0078] The base plate assembly 222 includes two base plates 2221, two conveyor belts 2225, a cross brace 2222, an adjusting plate 2223, a tensioning roller 2224, an adjusting bolt 2226, and a drive device 2227.

[0079] Each base plate 2221 is fixedly connected to the top of a sliding shaft 2212, and each conveyor belt 2225 is rotatably mounted on a base plate 2221. The two conveyor belts 2225 move synchronously to transport the pallet.

[0080] The conveyor belt 2225 is wound around the tension roller 2224, the adjusting plate 2223 is installed on both sides of the tension roller 2224, and the adjusting bolt 2226 is used to adjust the position of the tension roller 2224 to change the tension of the conveyor belt 2225.

[0081] The drive unit 2227 includes a servo motor 2227a, a drive shaft 2227c, a coupling 2227d, a mounting bearing seat 2227b, and a side plate 2227e.

[0082] Two base plates 2221 are respectively mounted on the drive shaft 2227c. The drive shaft 2227c is connected to the servo motor 2227a through the coupling 2227d. The servo motor 2227a drives the drive shaft 2227c to rotate and drives the conveyor belt 2225 to rotate.

[0083] Side plates 2227e are installed on both sides of the end of the conveyor belt 2225, and bearing housings 2227b are installed on the side plates 2227e. The drive shaft 2227c is connected to the coupling 2227d through the bearing housings 2227b.

[0084] like Figure 8 As shown, in this embodiment, at least one of the trays is a material vertical placement tray 24. The material vertical placement tray 24 includes a vertical material base 241 and multiple partitions 242. The multiple partitions 242 are vertically installed on the vertical material base 241 at intervals. A slot 243 for placing materials is formed between two adjacent partitions 242. The partitions 242 can be disassembled as needed to accommodate materials of different widths.

[0085] In other embodiments, such as Figure 9As shown, at least one of the pallets is a material horizontal placement pallet 25. The material horizontal placement pallet 25 includes a horizontal material base 251 and multiple baffles 252. The multiple baffles 252 are installed on the horizontal material base 251 and surround to form an area for placing materials.

[0086] like Figure 3 As shown, the main production line 40 is located on one side of the horizontal conveyor unit 23. The main production line 40 includes a main feeding area 41, a tape peeling area 42, a negative pressure suction plate 43, a main line air shaft 44, a limit retaining ring 45, and a bearing seat 46.

[0087] The negative pressure suction plate 43 is located on one side of the tape peeling area 42 and is used to adsorb and fix the material after traction. The negative pressure suction plate 43 uses a micro suction cup to evenly adsorb the material and prevent the material from shifting during the peeling process. The peeling accuracy of the tape 73 (the length of the residual tape 73 is ≤0.5mm) is much higher than that of traditional equipment.

[0088] The main air shaft 44 is located in the main machine loading area 41 and is mounted on the bearing seat 46.

[0089] The limiting ring 45 is installed on the main line air shaft 44 and is used to limit the material to be pulled.

[0090] The robotic arm 50 is connected to the automatic feeding tape peeling fixture 30 and is used to drive the automatic feeding tape peeling fixture 30 to move between the horizontal conveying unit 23 and the main production line 40.

[0091] Waste recycling box 60 is located between horizontal conveyor unit 23 and main production line 40.

[0092] like Figure 10-18 As shown, the automatic feeding tape peeling fixture 30 includes a material picking component 31, a feeding component 32, a feeding component 33, a tape peeling component 34, a pneumatic gripper 35, and a camera 36.

[0093] The material handling assembly 31 is used to pick up a material to be pulled on the pallet. The material handling assembly 31 includes a clamp body 311, a clamp body air shaft 312, a sliding shaft 313, and a linear bearing seat 314.

[0094] A linear bearing housing 314 is mounted on the clamp body 311, and a sliding shaft 313 is slidably mounted on the linear bearing housing 314. An air-expansion shaft 312 of the clamp body is sleeved outside the sliding shaft 313 and is used to extend into the core 71 of the material to be pulled, thereby tightening and gripping the material. This differs from the rigid clamping method often used in traditional feeding mechanisms, making it less likely to cause compression damage to the material.

[0095] The feeding assembly 32 is used to place the material to be pulled into the host loading area 41. The feeding assembly 32 includes a servo electric cylinder 321, a connecting plate 322, and a pusher plate 323.

[0096] The connecting plate 322 is installed at the end of the servo electric cylinder 321 and is fixedly connected to the pusher plate 323, which is sleeved on the outside of the air shaft 312 of the fixture body.

[0097] The servo electric cylinder 321 drives the pusher plate 323 and moves the material along the axis of the clamp body air expansion shaft 312 to transfer the material to the main machine loading area 41. At this time, the axes of the main air expansion shaft 44 and the clamp body air expansion shaft 312 are on the same straight line.

[0098] The material feeding assembly 33 is used to guide the material to be pulled to the tape peeling area 42. The material feeding assembly 33 includes a negative pressure adsorption body 331 and a contact plate 332.

[0099] The negative pressure adsorption body 331 is installed on the clamp body 311. The negative pressure adsorption body 331 has a vacuum chamber 3311. The contact plate 332 covers the bottom of the vacuum chamber 3311 and is used to adhere the release paper 731 of the tape 73. Multiple suction cup holes 3321 are evenly distributed on the contact plate 332. The suction cup holes 3321 are connected to the vacuum chamber 3311 and are used to transfer the negative pressure of the vacuum chamber 3311 to the surface of the release paper 731, thereby adsorbing the release paper 731 and preventing the material from shifting during the traction process.

[0100] like Figure 15-17 As shown, in this embodiment, the vacuum chamber 3311 consists of multiple segmented vacuum chambers 3311 that are not interconnected and are independently controlled. The corresponding segment is selected according to the width of the material to avoid most of the suction cup holes 3321 being exposed to the air when adsorbing narrow materials, which would continuously leak negative pressure, resulting in insufficient negative pressure and insufficient suction (materials are easy to fall off); when adsorbing wide materials, if the suction is concentrated in a local area, it will cause uneven force on the material and deformation.

[0101] like Figure 18 As shown, the tape peeling assembly 34 is used to peel the tape 73 of the material. The tape peeling assembly 34 includes peeling grippers 341, cylinder 342, and pin 343.

[0102] The cylinder 342 is mounted on the negative pressure adsorption body 331. One end of the peeling gripper 341 is hinged to the output shaft of the cylinder 342, and the other end is hinged to the negative pressure adsorption body 331 through the pin 343. The peeling gripper 341 is provided with a clamping part 3411. A clamping area is formed between the clamping part 3411 and the negative pressure adsorption body 331. The clamping area is used to accommodate the release paper 731 of the tape 73. The cylinder 342 drives the peeling gripper 341 to rotate to clamp the release paper 731 of the tape 73, and drives the clamp to move through the robotic arm 50, thereby peeling off the release paper 731.

[0103] The pneumatic gripper 35 is mounted on the clamp body 311 and is used to clamp and send the core 71 left on the main air shaft 44 to the waste recycling box 60.

[0104] The camera 36 is mounted on the clamp body 311 and is located on the same side as the pneumatic gripper 35. It is used to detect whether the material is pulled to the tape peeling area 42 and to send a position signal to the external control system to trigger the tape peeling assembly 34 to operate.

[0105] In this embodiment, the top of the clamp body 311 is provided with a connecting part for connecting with the robotic arm 50. The pneumatic gripper 35 and the clamp body air expansion shaft 312 are located on opposite sides of the clamp body 311. The negative pressure adsorption body 331 is installed on the side of the clamp body 311 and is located between the pneumatic gripper 35 and the clamp body air expansion shaft 312.

[0106] In this embodiment, there are multiple and equal numbers of inlets, feeding and switching areas, feeding and switching mechanisms 20, automatic feeding tape peeling clamps 30, and robotic arms 50. Multiple inlets are arranged along the length of the space capsule 10 on the front of the space capsule 10 for simultaneously conveying raw materials of different materials for hygiene products. Multiple feeding and switching areas are arranged inside the space capsule 10 along the extension direction of the internal channel 11. Each inlet is directly opposite a feeding and switching area. Each feeding and switching area is provided with a horizontal conveying unit 23. Each robotic arm 50 is arranged between a horizontal conveying unit 23 and the main production line 40. Each automatic feeding tape peeling clamp 30 is arranged at the end of a robotic arm 50. The outlet is arranged on the side of the space capsule 10 for outputting the final finished hygiene products.

[0107] In this application, the roll material 70 is a raw material for the production of absorbent articles, including a core 71, a material roll 72, and an adhesive tape 73. The adhesive layer 732 of the adhesive tape 73 is in direct contact with the material layer, and the release paper 731 covers the adhesive layer 732 and extends to the outside of the material roll 72.

[0108] The workflow for this application is as follows:

[0109] The pallet containing hygiene products is transported from the external loading area to the material starting station 211 of the feeding and conveying unit 21, and the feeding and conveying unit 21 transports the pallet to the lifting and conveying unit 22.

[0110] Linear bearing 2211 drives base plate 2221 and conveyor belt 2225 to rise to be flush with horizontal conveying unit 23, and servo motor 2227a drives conveyor belt 2225 to rotate to transport the loading tray to target material station 232.

[0111] The horizontal conveying unit 23 is activated and moves in the first direction, delivering a loading pallet from the target material station 232 to the second empty station 235. The horizontal conveying unit 23 then moves in the second direction, delivering a loading pallet from the target material station 232 to the first material station 231. At this time, the pallet originally on the second empty station 235 is conveyed to the second material station 233. The last pallet is conveyed to the target material station 232 by the conveyor belt 2225.

[0112] The processing equipment processes the materials in the three pallets according to user requirements. If the materials on the first material station 231 are used up first, the horizontal conveying unit 23 moves in the first direction and conveys the empty pallet on the first material station 231 to the target material station 232. At this time, the pallet on the original second material station 233 is on the second transfer control station, and the pallet on the original target material station 232 is on the second material station 233. If the materials on the second material station 233 are used up first, the horizontal conveying unit 23 moves in the second direction and conveys the empty pallet on the second material station 233 to the target material station 232. At this time, the pallet on the original first material station 231 is on the first transfer control station, and the pallet on the original target material station 232 is on the first material station 231. The linear bearing 2211 drives the base plate 2221 and the conveyor belt 2225 to descend to be flush with the feeding and conveying unit 21. The empty pallet returns to the material starting station 211 and waits to be reloaded.

[0113] The air shaft 312 of the clamp body of the automatic feeding tape peeling clamp 30 extends into the core 71 of the material to be pulled in order to tighten and pick up the material, and the clamp and the material are transferred to the main machine loading area 41 by the robotic arm 50.

[0114] Servo electric cylinder 321 drives pusher plate 323 and drives material to move along the axis of clamp body air expansion shaft 312. When limit stop ring 45 contacts material, it means that material is placed in place on main air expansion shaft 44.

[0115] The negative pressure adsorption body 331 adsorbs the release paper 731 of the adhesive tape 73 on the material, and the main production line 40 pulls one end of the material to the tape peeling area 42.

[0116] The negative pressure suction plate 43 adsorbs and fixes the material after traction, the cylinder 342 drives the peeling claw 341 to rotate to clamp the release paper 731 of the tape 73, and the mechanical arm 50 drives the clamp to move, thereby peeling off the release paper 731.

[0117] This application enables a cyclical material supply system from material loading and changing, gripping, transferring, and traction to tape 73 peeling. It can achieve uninterrupted material supply and full-process automation, improve equipment utilization and production efficiency, and ensure the production quality of semi-finished products and final products.

[0118] This application integrates multiple processes of "material picking-feeding-guiding-peeling" into a single fixture device, achieving a fully automated process with no manual intervention and coordinated controllable parameters for each process. This addresses core issues such as low efficiency, large positioning errors, and poor coordination in manual operation or decentralized equipment, thereby improving production efficiency. This application divides the vacuum chamber 3311 within the adsorption body into three independent sections. The vacuum system of the corresponding section is activated as needed, generating negative pressure in the suction cup hole 3321 of that section. By utilizing the "internal and external air pressure difference," materials of different widths are firmly adsorbed onto the contact plate 332, achieving flexible adaptation and stable adsorption of "narrow, medium, and wide" materials.

[0119] This application utilizes at least three pallets in conjunction with continuous material stations. Loading pallets can be sequentially transported to each material station to supply materials to the production line, while empty pallets are returned via the target material station 232. The entire process requires no machine downtime, completely eliminating production downtime. This application sets up an independent empty transfer station. When pallets are transferred, their positions are adjusted at the empty transfer station before entering the target material station 232, avoiding direct collisions or offsets between multiple pallets and significantly reducing the risk of material jamming. Due to the wide variety of material specifications on the main line, this application designs corresponding pallet structures, namely, vertically placed material pallets 24 and horizontally placed material pallets 25. These can be adjusted arbitrarily according to different sizes and widths, exhibiting strong compatibility and greatly improving applicability.

[0120] This application integrates all the mechanisms into a closed space capsule 10. The space capsule 10 adopts a modular structure design. The two ends use a unified module that remains unchanged, while the middle units are grouped together. Moreover, the modular structure facilitates assembly and maintenance, adapts to existing production processes, and ensures design quality while controlling manufacturing costs and improving production efficiency in the use of materials and manufacturing process.

[0121] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
