Description

Technical Field

[0001] This invention relates to the field of fiber composite material manufacturing technology, specifically a sheet molding compound cutting and winding device. Background Technology

[0002] Sheet molding compounds are an important type of thermosetting molding compound. Due to their excellent mechanical properties, electrical properties, and corrosion resistance, they are widely used in the automotive industry, rail transportation, electrical insulation, and construction engineering. In actual production and processing, sheet molding compounds are usually supplied in roll form. They need to be unwound, conveyed to a fixed length, and cut into sheets of specific sizes before subsequent molding or lamination. Traditional sheet molding compound cutting processes often use offline cutting methods or set up fixed cutting stations on continuous production lines. In these processes, in order to ensure cutting accuracy and prevent the material from being pulled or piled up during the cutting process, the sheet molding compound raw material usually needs to be temporarily stopped or run at low speed at the moment of cutting. The normal conveying speed is resumed after the cutting blade has completed its action.

[0003] However, with the improvement of industrial automation and the continuous increase in the requirements for production efficiency, this traditional "walk-stop-walk" intermittent cutting method has revealed obvious limitations. First, frequent start-stop actions increase the inertial impact and energy consumption of the mechanical system, reducing the service life of the equipment. During frequent acceleration and deceleration, material tension fluctuations are easily caused, leading to cutting position deviation or uneven cuts, which seriously affects the dimensional accuracy and stacking regularity of the finished sheet material, increasing the scrap rate. Frequent shutdown actions greatly limit the operating speed of the entire production line, becoming a bottleneck restricting capacity improvement. Therefore, how to achieve non-stop cutting of sheet molding compounds under continuous conveying conditions has become a key technical problem that urgently needs to be solved in the industry. Summary of the Invention

[0004] The purpose of this invention is to provide a sheet molding compound cutting and winding device to solve the problem that the cutting process in the prior art requires machine downtime.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sheet molding compound cutting and winding device, comprising an adjustable frame assembly, a guiding and conveying component, a swing arm cutting component, and a loading platform, wherein the guiding and conveying component is disposed on the adjustable frame assembly, the loading platform is located below the adjustable frame assembly, and the swing arm cutting component comprises a synchronous swing arm and a cutting roller assembly;

[0006] The cutting roller assembly includes an elastic cutting roller and a pressure roller. The elastic cutting roller includes a fixed roller body, cutting blades, a blade holder, an elastic connecting assembly, and a coaxial pull rope drive module. Both the fixed roller body and the cutting roller assembly are mounted on a synchronous swing arm. The fixed roller body has a blade outlet groove. The cutting blades are mounted on the blade holder, which is movably installed inside the fixed roller body via the elastic connecting assembly. The coaxial pull rope drive module is rotatably mounted on the fixed roller body and connected to the blade holder. The synchronous swing arm is rotatably mounted on a guide conveyor component.

[0007] Before the device is put into operation, the operator introduces sheet molding compound raw material. Then, through the control system, the guide conveyor moves on the adjustable frame assembly. The swing arm cutting component moves synchronously with the guide conveyor. After the guide conveyor and the swing arm cutting component reach the preset working position, the operator drives the guide conveyor to operate through the control system. The guide conveyor transports the sheet molding compound raw material to the swing arm cutting component. The sheet molding compound raw material is transported to the loading platform between the synchronous swing arms. During the transportation process, the synchronous swing arms swing back and forth at a uniform speed, and the left and right swing angles are the same. This makes the landing point of the sheet molding compound raw material fall evenly laterally with the uniform swing of the synchronous swing arms. The sheet molding compound raw materials falling at different times are then neatly stacked laterally. The stacked outline and arrangement of all sheet molding compound raw materials are consistent, achieving uniform and neat stacking of materials.

[0008] During the raw material transportation process, the coaxial pull rope transmission module operates, and the coaxial pull rope transmission module pulls the knife holder to retract in the knife slot. The elastic connecting component undergoes elastic deformation under the pressure of the knife holder. While the knife holder is moving, it drives the cutting blade to retract synchronously, so that the cutting blade is completely retracted inside the fixed roller during the raw material transportation process, preventing the cutting blade from scratching the sheet molding compound raw material during the raw material transportation process.

[0009] After the sheet molding compound material is stored, when it needs to be cut, the coaxial pull rope transmission module instantly releases the tension on the cutter holder, and the elastic connecting component instantly elastically resets, ejecting the cutter holder and cutting blade from the cutter slot. Because the synchronous swing arm rotates coaxially, the elastic cutting roller and the pressure roller are always in the corresponding position. The ejected cutting blade, in conjunction with the pressure roller, cuts the sheet molding compound material in one go. After the cutting operation is completed, the coaxial pull rope transmission module pulls the cutter holder back, and the cutting blade resets and retracts, waiting for the next cutting operation command.

[0010] The coaxial pull rope transmission module includes a double-groove coaxial pulley, a pull rope, and an outer power unit. The double-groove coaxial pulley is rotatably mounted on a fixed roller body. Two winding grooves are symmetrically opened on the double-groove coaxial pulley. One end of the pull rope is wound around the winding groove, and the other end of the pull rope is connected to the cutter holder. The outer power unit passes through the fixed roller body and is connected to the double-groove coaxial pulley. The outer power unit consists of a servo motor, a reducer, and an electromagnetic clutch. The output end of the servo motor is connected to the reducer. The output shaft of the reducer is fixedly connected to the driving hub of the electromagnetic clutch, and the driven hub of the electromagnetic clutch is rigidly connected to the shaft of the double-groove pulley.

[0011] During the raw material conveying process, the outer power unit drives the double-groove coaxial pulley to rotate. The pull rope continuously winds around the winding groove, maintaining tension on the cutter holder and causing the cutting blade to continuously retract inside the fixed roller, preventing scratch damage to the sheet molding compound raw material during the conveying process. When a cutting operation is required, the outer power unit instantly reverses its rotation, quickly releasing the pull rope. After losing tension constraint, the elastic connecting component instantly resets, pushing the cutting blade to pop out and complete the cutting operation. After the cutting is completed, the outer power unit rotates forward again to retract the pull rope, pulling the cutter holder and cutting blade back to their original positions, ready for the next operation.

[0012] The pressure roller includes a roller shaft and an elastic sleeve. The roller shaft is rotatably mounted on a synchronous swing arm. The surface of the roller shaft is fitted with an elastic sleeve, which is made of wear-resistant and resilient materials such as cast polyurethane or high-elastic natural rubber. During the cutting process, when the cutting blades pop out, the blades can cut into the elastic sleeve to a certain depth, ensuring that the blades completely cut the sheet molding compound material and preventing incomplete cutting or material sticking. At the same time, the elastic sleeve can buffer the impact force of the cutting blades, reduce the impact damage to the cutting blades, and extend the service life of the cutting blades.

[0013] The synchronous swing arm includes a swing arm assembly, a rotating component, and a drive source. The rotating component is rotatably connected to the guiding and conveying component. The output end of the drive source passes through the guiding and conveying component and is connected to the rotating component. The swing arm assembly is mounted on the rotating component. The drive source is a drive motor. During the transportation of sheet molding compound raw materials, the drive source drives the rotating component to rotate back and forth at a uniform speed, so that the swing arm assembly maintains synchronous swinging. This drives the elastic cutting roller and the pressure roller to shift left and right synchronously and uniformly, allowing the falling sheet molding compound raw materials to be evenly spread laterally. This ensures that the overall outline of the stacked raw materials is regular and that there are no problems such as excessive local stacking or skewing.

[0014] The swing arm assembly includes swing arm one and swing arm two, which are synchronously linked. Swing arm one is connected to the fixed roller body, and swing arm two is connected to the pressure roller. During material transportation, swing arm one and swing arm two maintain a fixed relative position to ensure that the elastic cutting roller and the pressure roller are always in corresponding contact and will not be misaligned during the swinging process, thus avoiding cutting failure caused by the mismatch between the blade and the pressure roller during cutting.

[0015] The guiding and conveying component includes an active conveying element and a driven conveying element. The active conveying element includes an active roller, a roller frame, and a second drive source. The roller frame is mounted on an adjustable frame assembly, and the active roller is rotatably mounted on the roller frame. The output end of the second drive source passes through the roller frame and is connected to the active roller. The driven conveying element is slidably connected to the adjustable frame assembly. The second drive source is a drive motor. Before operation, the sheet molding compound is introduced into the guiding and conveying component by the operator. The second drive source is activated through the operation control system, which drives the active roller to rotate. The material is conveyed by friction, and the sheet molding compound raw material is steadily conveyed forward. The position of the driven conveying element on the adjustable frame assembly can be adjusted according to different working positions to adapt to different conveying needs.

[0016] The adjustable frame assembly includes a frame and a moving module. The moving module is mounted on the frame, and the roller frame is mounted on the moving module. The frame has a moving groove, and the driven conveying element is slidably mounted on the moving groove. The moving module is a screw and nut moving mechanism. The moving module can drive the roller frame to move stably along the frame, thereby driving the guide conveying component and the swing arm cutting component to move as a whole and adjust the working position. At the same time, the length of the conveying section can be changed by adjusting the position of the driven conveying element in the moving groove to adapt to the production needs of raw materials of different lengths.

[0017] It also includes a control system. The adjustable frame assembly, guide conveyor components, synchronous swing arm and coaxial pull rope transmission module are all electrically connected to the control system. The staff can uniformly control the operating status of each component through the control system, realize the adjustment of conveying position, the control of swing speed and the synchronous control of cutting timing, ensure smooth connection of each process, improve the automation level of cutting and winding operations, reduce the intensity of manual operation and ensure stable operation accuracy.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention achieves non-stop impact cutting through the cooperation of a coaxial pull rope transmission module, an elastic connecting component, and a blade and pressure roller. During the normal material conveying stage, the outer power unit operates, and the double-groove coaxial pulley continuously winds up the pull rope, pulling the blade holder to compress the elastic connecting component. The cutting blade is completely retracted and stored inside the blade groove of the fixed roller, preventing the blade from contacting the moving material and scratching the surface of the sheet molding compound during the conveying stage. When cutting is required, there is no need to stop feeding. Simply disconnect the electromagnetic clutch to quickly release the pull rope tension. The elastic connecting component instantly rebounds, pushing the cutting blade out at high speed. The blade cuts into the elastic pad to complete a full-width cut. After cutting, the power unit quickly winds up the rope to reset the blade. Material conveying does not need to be interrupted, truly realizing dynamic non-stop cutting during continuous feeding, balancing product yield and equipment continuous production capacity.

[0020] 2. This invention utilizes an adjustable frame assembly, guiding and conveying components, synchronous swing arms, and a loading platform in a coordinated manner. During the raw material conveying process, the drive source continuously drives swing arms one and two to swing synchronously and uniformly at a constant speed, causing the falling point of the sheet molding compound to shift laterally evenly. The material is then stacked neatly and uniformly on the loading platform, eliminating the need for repeated start-stop operations to adjust the material stacking. This significantly shortens production intervals, improves the continuous processing efficiency of the entire production line, and avoids defects such as localized thickening, skewing, and inconsistent stacking contours. It ensures that each batch of materials to be cut has uniform specifications and reduces subsequent cutting dimensional deviations. Attached Figure Description

[0033] The technical solutions of 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.

[0034] Specific Implementation Example 1: As shown in the example Figure 1 - Figure 10 As shown, the present invention provides a technical solution: a sheet molding compound cutting and winding device, including an adjustable frame assembly 1, a guide conveying component 2, a swing arm cutting component 3, and a loading platform 4. The guide conveying component 2 is disposed on the adjustable frame assembly 1, and the loading platform 4 is located below the adjustable frame assembly 1. The swing arm cutting component 3 includes a synchronous swing arm 31 and a cutting roller group 32.

[0035] The cutting roller assembly 32 includes an elastic cutting roller 33 and a pressure roller 34. The elastic cutting roller 33 includes a fixed roller body 331, a cutting blade 332, a blade holder 333, an elastic connecting component 334, and a coaxial pull rope transmission module 335. Both the fixed roller body 331 and the cutting roller assembly 32 are mounted on the synchronous swing arm 31. The fixed roller body 331 has a blade outlet groove 3331. The cutting blade 332 is mounted on the blade holder 333. The blade holder 333 is movably mounted inside the fixed roller body 331 through the elastic connecting component 334. The coaxial pull rope transmission module 335 is rotatably mounted on the fixed roller body 331 and is connected to the blade holder 333. The synchronous swing arm 31 is rotatably mounted on the guide conveyor component 2.

[0036] Before the device is put into operation, the staff introduces the sheet molding compound material. Then, through the control system, the guide conveyor 2 moves on the adjustable frame assembly 1. The swing arm cutting component 3 moves synchronously with the guide conveyor 2. After the guide conveyor 2 and the swing arm cutting component 3 reach the preset working position, the staff drives the guide conveyor 2 to run through the operation control system. The guide conveyor 2 transports the sheet molding compound material to the swing arm cutting component 3. The sheet molding compound material is transported to the loading platform 4 between the synchronous swing arms 31. During the transportation process, the synchronous swing arms 31 swing back and forth at a uniform speed, and the left and right swing angles are the same. This makes the falling point of the sheet molding compound material fall from between the synchronous swing arms 31 and shift laterally evenly with the uniform swing of the synchronous swing arms 31. The sheet molding compound material falling at different times is then neatly stacked in the lateral direction. The stacked outline and arrangement of all sheet molding compound materials are consistent, so as to achieve the material's shape, uniformity and neatness in stacking.

[0037] During the raw material transportation process, the coaxial pull rope transmission module 335 operates, pulling the cutter holder 333 to retract within the cutter groove 3331. The elastic connecting component 334 undergoes elastic deformation under the pressure of the cutter holder 333. Simultaneously, the cutter holder 333 drives the cutting blade 332 to retract synchronously, ensuring that the cutting blade 332 is completely retracted inside the fixed roller 331 during the raw material transportation process, preventing the cutting blade 332 from scratching the sheet molding compound raw material during the material conveying process.

[0038] After the sheet molding compound material is stored, when it needs to be cut, the coaxial pull rope transmission module 335 instantly releases the tension on the cutter holder 333, and the elastic connecting component 334 instantly and elastically resets, ejecting the cutter holder 333 and the cutting blade 332 from the cutter slot 3331. Because the synchronous swing arm 31 rotates coaxially, the elastic cutting roller 33 and the pressure roller 34 are always in the corresponding position. The ejected cutting blade 332, together with the pressure roller 34, cuts the sheet molding compound material in one go. After the cutting operation is completed, the coaxial pull rope transmission module 335 pulls the cutter holder 333 back, and the cutting blade 332 resets and retracts, waiting for the next cutting operation instruction.

[0039] The coaxial pull rope transmission module 335 includes a double-groove coaxial pulley 3351, a pull rope 3352, and an outer power unit 3353. The double-groove coaxial pulley 3351 is rotatably mounted on the fixed roller body 331. Two winding grooves 3354 are symmetrically opened on the double-groove coaxial pulley 3351. One end of the pull rope 3352 is wound on the winding groove 3354, and the other end of the pull rope 3352 is connected to the cutter holder 333. The outer power unit 3353 passes through the fixed roller body 331 and is connected to the double-groove coaxial pulley 3351. The outer power unit 3353 consists of a servo motor, a reducer, and an electromagnetic clutch. The output end of the servo motor is connected to the reducer. The output shaft of the reducer is fixedly connected to the driving hub of the electromagnetic clutch, and the driven hub of the electromagnetic clutch is rigidly connected to the double-groove coaxial pulley 3351.

[0040] During the material conveying process, the outer power unit 3353 drives the double-groove coaxial pulley 3351 to rotate, and the pull rope 3352 continuously winds around the winding groove 3354, maintaining the tension on the cutter holder 333, so that the cutting blade 332 continuously retracts inside the fixed roller 331, preventing scratch damage to the sheet molding compound material during the conveying process. When a cutting operation is required, the outer power unit 3353 instantly reverses its rotation, quickly releasing the pull rope 3352. After losing the tension constraint, the elastic connecting component 334 instantly resets, pushing the cutting blade 332 to pop out and complete the cutting operation. After the cutting is completed, the outer power unit 3353 rotates forward again to retract the pull rope 3352, pulling the cutter holder 333 and the cutting blade 332 back to their original positions, waiting for the next operation.

[0041] The synchronous swing arm 31 includes a swing arm assembly 311, a rotating component 312, and a drive source 313. The rotating component 312 is rotatably connected to the guide conveying component 2. The output end of the drive source 313 passes through the guide conveying component 2 and is connected to the rotating component 312. The swing arm assembly 311 is mounted on the rotating component 312. The drive source 313 is a drive motor. During the transportation of sheet molding compound raw materials, the drive source 313 drives the rotating component 312 to rotate back and forth at a uniform speed, so that the swing arm assembly 311 maintains synchronous swinging. This drives the elastic cutting roller 33 and the pressure roller 34 to shift left and right synchronously and uniformly, so that the falling sheet molding compound raw materials can be evenly spread out laterally, ensuring that the overall outline of the stacked raw materials is regular and that there will be no problem of excessive local stacking or skewing.

[0042] The swing arm assembly 311 includes a swing arm 3111 and a swing arm 3112. The swing arm 3111 and the swing arm 3112 move synchronously. The swing arm 3111 is connected to the fixed roller body 331, and the swing arm 3112 is connected to the pressure roller 34. During the material transportation process, the swing arm 3111 and the swing arm 3112 maintain a fixed relative position to ensure that the elastic cutting roller 33 and the pressure roller 34 are always in corresponding contact and will not be misaligned during the swing process, thus avoiding cutting failure caused by the mismatch between the blade and the pressure roller 34 during cutting.

[0043] The guiding and conveying component 2 includes an active conveying element 21 and a driven conveying element 22. The active conveying element 21 includes an active roller 211, a roller frame 212, and a second drive source 213. The roller frame 212 is mounted on the adjustable frame assembly 1. The active roller 211 is rotatably mounted on the roller frame 212. The output end of the second drive source 213 passes through the roller frame 212 and is connected to the active roller 211. The driven conveying element 22 is slidably connected to the adjustable frame assembly 1. The second drive source 213 is a drive motor. Before operation, the sheet molding compound is introduced into the guiding and conveying component 2 by the operator. The second drive source 213 is started by the operation control system. The second drive source 213 drives the active roller 211 to rotate. The material is conveyed by friction, and the sheet molding compound raw material is steadily conveyed forward. The position of the driven conveying element 22 on the adjustable frame assembly 1 can be adjusted according to different working positions to adapt to different conveying needs.

[0044] The adjustable frame assembly 1 includes a frame 11 and a moving module 12. The moving module 12 is mounted on the frame 11, and the roller frame 212 is mounted on the moving module 12. The frame 11 has a moving groove 111. The driven conveying element 22 is slidably mounted on the moving groove 111. The moving module 12 is a screw and nut moving mechanism. The moving module 12 can drive the roller frame 212 to move stably along the frame 11, thereby driving the guide conveying component 2 and the swing arm cutting component 3 to move as a whole and adjust the working position. At the same time, the length of the conveying section can be changed by adjusting the position of the driven conveying element 22 in the moving groove 111 to adapt to the production needs of raw materials of different lengths.

[0045] It also includes a control system. The adjustable frame assembly 1, the guide conveyor component 2, the synchronous swing arm 31 and the coaxial pull rope transmission module 335 are all electrically connected to the control system. The staff can uniformly control the operating status of each component through the control system, realize the adjustment of the conveying position, the control of the swing speed and the synchronous control of the cutting time, ensure the smooth connection of each process, improve the automation level of the cutting and winding operation, reduce the intensity of manual operation and ensure the stability of the operation accuracy.

[0046] Specific Implementation Example 2: As shown in the example Figure 11 As shown, a pressure roller 34 different from that in Embodiment 1 is provided. The difference is that in this embodiment, an elastic sleeve 342 made of highly elastic and wear-resistant material is provided on the outer surface of the roller shaft 341. During cutting, the high-speed impact of the blade can be buffered, and the blade can be prevented from directly hitting the metal roller shaft, which greatly reduces the problems of chipping and curling, and extends the service life of the blade.

[0047] The specific content is as follows:

[0048] The pressure roller 34 includes a roller shaft 341 and an elastic sleeve 342. The roller shaft 341 is rotatably mounted on the synchronous swing arm 31. The elastic sleeve 342 is sleeved on the surface of the roller shaft 341. The elastic sleeve 342 is made of wear-resistant and resilient materials such as cast polyurethane and high-elastic natural rubber. When the cutting blade 332 is ejected during the cutting process, the blade can cut into the elastic sleeve 342 to a certain depth, ensuring that the blade completely cuts the sheet molding compound material and preventing incomplete cutting or material sticking. At the same time, the elastic sleeve 342 can buffer the impact force of the cutting blade 332, reduce the impact damage to the cutting blade 332, and extend the service life of the cutting blade 332.

[0049] Working principle of the invention:

[0050] Before the operation starts, the staff introduces the sheet molding compound material into the guide conveyor 2. The control system controls the movement of the moving module 12. The moving module 12 drives the roller frame 212 and the active conveying element 21 to move as a whole. The guide conveyor 2 then moves on the adjustable frame assembly 1, and the swing arm cutting component 3 moves synchronously with the guide conveyor 2.

[0051] After the guide conveyor 2 and the swing arm cutting component 3 are adjusted to the preset working position, the control system starts the second drive source 213. The second drive source 213 drives the active roller 211 to rotate. The active roller 211 cooperates with the driven conveyor element 22 to convey the sheet molding compound material. The sheet molding compound material is conveyed to the swing arm cutting component 3 and passes between the synchronous swing arms 31, and finally falls to the top of the loading platform 4.

[0052] During the continuous material conveying and stacking stage, the drive source 313 drives the rotating component 312 to rotate back and forth at a uniform speed. The rotating component 312 drives the swing arm group 311 to swing synchronously. The swing arm one 3111 and the swing arm two 3112 in the swing arm group 311 are linked synchronously. The swing arm one 3111 drives the fixed roller body 331 and the elastic cutting roller 33 to move. The swing arm two 3112 drives the pressure roller 34 to move. The elastic cutting roller 33 and the pressure roller 34 always maintain a corresponding position. The synchronous swing arm 31 swings back and forth at a uniform speed and the left and right swing angles are consistent. The landing point of the sheet molding compound material falling from the synchronous swing arm 31 is laterally and uniformly offset with the swing. The sheet molding compound material is horizontally and neatly stacked on the loading platform 4, and the stacking outline is uniform.

[0053] During the material conveying and stacking process, the outer power unit 3353 works continuously. The torque output by the servo motor is transmitted to the electromagnetic clutch through the reducer. The electromagnetic clutch engages and drives the double-groove coaxial pulley 3351 to rotate continuously. The pull rope 3352 is continuously wound inside the winding groove 3354. The pull rope 3352 continuously pulls the cutter holder 333. The cutter holder 333 squeezes the elastic connecting component 334 to make it elastically deform. The cutter holder 333 drives the cutting blade 332 to retract. The cutting blade 332 is completely stored inside the fixed roller body 331 to prevent the cutting blade 332 from scratching the sheet molding compound material during the conveying process.

[0054] When the sheet molding compound raw material on the loading platform 4 is stacked to the set size and a cutting operation is required, the electromagnetic clutch of the outer power unit 3353 is disengaged, releasing the constraint on the double-groove coaxial pulley 3351. The elastic connection component 334 is instantly elastically reset, pushing the cutter holder 333 to carry the cutting blade 332 outward at high speed along the cutting groove 3331.

[0055] The cutting blade 332 impacts the sheet molding compound material and presses it against the surface of the elastic sleeve 342 of the pressure roller 34. The elastic sleeve 342 undergoes a slight deformation, and the blade cuts into the elastic sleeve 342 to a certain depth, completing the one-time cutting of the sheet molding compound material. At the same time, the elastic sleeve 342 buffers the impact load of the cutting blade 332 and protects the blade.

[0056] After a single cut is completed, the outer power unit 3353 re-establishes the transmission connection, drives the double-groove coaxial rope wheel 3351 to rotate and wind up the pull rope 3352. The pull rope 3352 pulls the cutter holder 333 back, and the cutting blade 332 is retracted back into the fixed roller body 331. The device enters standby mode, waiting for the control system to issue the next round of cutting instructions.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
