Description

Technical Field

[0001] This invention relates to the field of wire processing, specifically a wire threading processing device. Background Technology

[0002] Silicone wire is a special type of wire that uses silicone rubber as its insulation material. It is renowned for its excellent resistance to high and low temperatures (typically ranging from -60℃ to 200℃), superior flexibility, good insulation, and chemical stability. These properties make it particularly suitable for the new energy field (such as high-voltage wiring harnesses inside battery packs and charging systems in new energy vehicles), internal wiring of various electrical motors, and circuit connections in harsh environments, heat sources, or frequent bending in industrial machinery and equipment. It is a key component ensuring the stable and safe operation of equipment under extreme conditions.

[0003] In the wire harness processing of silicone wires, in order to meet the requirements of mechanical protection, insulation enhancement and easy installation of the above application scenarios, it is often necessary to integrate multiple silicone wires into a silicone sleeve or high-temperature corrugated pipe, which is called "threading" or "pipe threading". Commonly used equipment for threading processing includes semi-automatic threading machines. The specific operation is as follows: the operator fixes the sleeve to one end of the equipment, puts the wire end into the guide port or clamping device, and then pushes the wire into the sleeve through the friction wheel or simple push rod by step switch or button.

[0004] During use and observation, it was found that in order to prevent the wire from exceeding the end of the sleeve due to excessive length during the above-mentioned wire threading process, i.e., to prevent "over-threading", two limiting measures are generally adopted. One is manual intervention, in which the operator visually judges the progress of wire threading and manually controls the start and stop of the machine through a foot switch or similar device. The other is to pre-install physical limiting components (such as wire lugs or clips) at the end of the wire. When the component moves to the sleeve entrance, it is mechanically blocked because its size is larger than the sleeve opening, thereby preventing the wire from going further. However, the manual intervention method relies too much on human visual inspection and is difficult to synchronize with the stable and high-speed working rhythm of the machine. Pre-installing structural components requires additional installation operations for the limiting components. For detachable limiting components, disassembly operations are also required, increasing the complexity of the wire threading operation.

[0005] Therefore, a wire threading processing device is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A wire threading processing device of this invention includes a base, on which a vertical plate is fixedly mounted; the two sides of the vertical plate are a processing side and an equipment side, respectively; the processing side is provided with a sleeve and multiple wires; the equipment side is provided with a first cylinder, the output end of which is fixedly connected to a first rack, which is slidably connected to the top of the base; the first rack meshes with a first gear, which is rotatably connected to the equipment side; a second conveying roller is rotatably connected to the processing side, and the second conveying roller is concentrically arranged with the first gear; a one-way transmission mechanism is provided between the first gear and the second conveying roller for... One-way intermittent rotational power is transmitted to the second conveyor roller; a first conveyor roller is provided above the second conveyor roller, and a second gear is fixedly connected to the end of the first conveyor roller; a third gear meshes with the bottom of the second gear; the third gear is fixedly connected to the second conveyor roller; a second cylinder is provided on the side of the equipment to drive the first conveyor roller to move closer to or away from the second conveyor roller; the upright plate is also provided with a limiting component for constraining the wire and a fixing component for clamping the sleeve; by controlling the start of the first cylinder through the meshing action of the first rack and the first gear, a fixed length of wire can be conveyed each time, thereby making the entire wire threading process controllable and predictable, and reducing the risk of over-threading the wire during wire threading.

[0008] Preferably, the unidirectional transmission mechanism includes a first circular plate fixed to the first gear, and a plurality of abutments with arc-shaped surfaces fixed to the outer wall of the first circular plate; a second circular plate is fixed to the end of the second conveying roller; the second circular plate is connected to a pressure plate by a spring, and the pressure plate is provided with a protrusion that cooperates with the second circular plate, the protrusion being used to restrict the axial displacement of the pressure plate along the second circular plate.

[0009] Preferably, the vertical plate processing side is provided with a braking system; the braking system includes a rotatably arranged third conveyor roller and a fourth conveyor roller, with the third conveyor roller located above the fourth conveyor roller; a triggering mechanism is provided at the end of the fourth conveyor roller, and a braking actuator is provided between the fourth conveyor roller and the second conveyor roller; the triggering mechanism is linked with the braking actuator, and when the wire is disengaged from the third and fourth conveyor rollers, the triggering mechanism brakes the second conveyor roller through the braking actuator; the triggering mechanism includes a connecting block fixedly disposed at the end of the fourth conveyor roller and a second rack fixedly connected to the connecting block; the connecting block and A spring rod is fixedly connected between the top of the base; the braking actuator includes a fourth gear rotatably connected to the vertical plate and a lever fixedly connected to the fourth gear; the fourth gear and the lever are eccentrically arranged; the fourth gear meshes with the second rack; the lever is provided with a third rack, and a fifth gear meshing with the third rack is fixedly connected to the second conveying roller; through the cooperation of the third rack and the fifth gear, when the lever is reset under the meshing action of the second rack and the fourth gear, the third rack can move closer to the fifth gear and mesh with the fifth gear, so as to forcibly brake the fifth gear and the second conveying roller directly connected to it.

[0010] Preferably, the limiting component includes at least one first fixing plate fixedly disposed on the surface of the upright plate; the first fixing plate has multiple through slots separated by partitions; the shape of the partitions can be adjusted according to the number of wires, that is, the first fixing plate can be replaced as a whole. The figure shows three wires as an example. The partitions can forcibly isolate adjacent wires to reduce friction, entanglement and other situations caused by contact during wire threading, thereby improving the threading quality of the device.

[0011] Preferably, the top of the first fixing plate has a channel; the inner wall of the first fixing plate has multiple sliding grooves; the end of the partition is rotatably connected to a guide wheel, and the guide wheel and the sliding groove are in sliding fit; the first fixing plate is also provided with a locking mechanism for locking the position of the guide wheel; by setting the channel and the rotatably set partition, when the wire length is short, the limiting component can be appropriately added, that is, the length between the multiple first fixing plates is slightly shorter than the wire. When feeding the wire, the wire is placed above the channel of the multiple first fixing plates, and the wire is put into the empty slot in the first fixing plate through the channel. As the wire is continuously put into the channel, the partition can rotate and separate the wire, which can simplify the cumbersome operation of aligning and passing the wire through the slot in the first fixing plate when feeding the wire in the traditional way.

[0012] Preferably, the locking mechanism includes a first electromagnet fixed to the bottom of a first fixed plate; a cavity is provided in the first fixed plate, and a locking plate is slidably fitted in the cavity; a spring is fixed between the locking plate and the cavity; a magnetic core is fixed to the bottom of the locking plate; the magnetic core and the first electromagnet are magnetically repelled; at least one pointer is fixed to the outside of the partition, and the pointer is used to position the guide wheel; the locking plate can extend out of the cavity under magnetic force and engage with the guide wheel; when the wire is short, it can be directly fed from top to bottom. After feeding, the operator can observe whether the pointer on the outside of the partition is aligned with the center line on the first fixed plate. If it is not aligned, the operator can manually adjust it. After alignment, the first electromagnet can be energized. Multiple first electromagnets are connected in series. After the first electromagnet is energized, the magnetic core can be driven by the magnetic force to push the locking plate out. The locking plate can constrain the guide wheel on the partition to fix the partition as a whole, which can improve the stability of the partition when the wire is transported.

[0013] Preferably, a second electromagnet is provided on the top of the connecting block, and the second electromagnet and the connecting block are magnetically attracted to each other; the second electromagnet is connected in parallel with the first electromagnet and driven by the same control circuit, which is configured to supply power to the first electromagnet and the second electromagnet in a time-sharing manner; by setting the second electromagnet, the third conveying roller and the fourth conveying roller are initially separated. After the operator completes the constraint of the wire and starts the first electromagnet, the second electromagnet will also start and apply magnetic force to the connecting block, which can move the connecting block upward and reduce the gap between the fourth conveying roller and the third conveying roller to only the wire remains. This setting simplifies the operation of manually moving the fourth conveying roller downward when initially feeding the wire.

[0014] Preferably, the fixing assembly includes a second fixing plate and a third fixing plate fixedly mounted on the upright plate; the second fixing plate is slidably provided with a plurality of first sliders with support plates fixed to their ends, the support plates being used to expand the inner wall of the sleeve; the third fixing plate is slidably provided with a plurality of second sliders with arc-shaped ends, the second sliders being used to clamp the outer wall of the sleeve; when initially fixing the sleeve, the operator can first put the end of the sleeve onto the support plates of the plurality of first sliders, and then control the plurality of first sliders to move outward and the second sliders to move inward respectively. The outward movement of the first sliders can pre-expand the support plates on the inlet end of the sleeve, facilitating the subsequent insertion of the wire, and the inward movement of the second sliders can clamp the outer wall of the sleeve, so that the sleeve is fixed in a fixed state when the wire is inserted.

[0015] Preferably, a threaded sleeve is provided between the second and third fixing plates, and a screw is threadedly connected to one side of the threaded sleeve via an ear plate; the screw and the second and third fixing plates are rotatably connected; the threaded sleeve is rotatably connected to the first and second sliders via a connecting rod; rotating the screw can drive the first and second sliders to move in opposite directions; after the end of the sleeve is pressed against the outside of multiple support plates, the operator can rotate the screw to drive the threaded sleeve to move laterally under the action of threaded transmission. When the threaded sleeve moves, the connecting rod can be used to coordinately control the second and first sliders on both sides, driving the second and first sliders to move in opposite directions, improving the convenience of the operator in adjusting the second and first sliders.

[0016] Preferably, a crossbar is fixedly connected between the second fixing plate and the third fixing plate; the threaded sleeve is slidably connected to the crossbar through an ear plate; by setting the crossbar, the crossbar and the threaded sleeve form a sliding pair, which can further improve the constraint effect on the threaded sleeve during thread transmission and improve the stability of the threaded sleeve during movement.

[0017] The advantages of this invention are:

[0018] 1. The wire threading processing device of the present invention, by controlling the start of the first cylinder through the meshing action of the first rack and the first gear, can achieve the feeding of a fixed length of wire each time, thereby making the entire threading process controllable and predictable, and reducing the risk of over-threading of wires.

[0019] 2. The wire threading processing device of the present invention involves a second rack meshing with a fourth gear, which drives a lever to deflect, thereby enabling the lever to brake the second conveying roller via a control component. 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 examples are given below.

[0035] Please see Figures 1 to 11As shown in the embodiment of the present invention, a wire threading processing device includes a base 1, on which a vertical plate 12 is fixedly mounted; the two sides of the vertical plate 12 are a processing side and an equipment side, respectively; a first cylinder 13 is provided on the equipment side, and a first rack 17 is fixedly connected to the output end of the first cylinder 13, the first rack 17 being slidably connected to the top of the base 1; the first rack 17 meshes with a first gear 18, the first gear 18 being rotatably connected to the equipment side; a second conveying roller 111 is rotatably connected to the processing side, the second conveying roller 111 being concentrically arranged with the first gear 18; a one-way transmission mechanism is provided between the first gear 18 and the second conveying roller 111 for transmitting the intermittent rotational power of the first gear 18 to the second conveying roller 111 in one direction; a first conveying roller 16 is provided above the second conveying roller 111, the first conveying roller 16 having an end A second gear 181 is fixedly connected to the first gear 181; a third gear 182 meshes with the bottom of the second gear 181; the third gear 182 is fixedly connected to the second conveying roller 111; a second cylinder 15 is provided on the side of the equipment for driving the first conveying roller 16 to approach or move away from the second conveying roller 111; the upright plate 12 is also provided with a limiting component for constraining the wire a and a fixing component for clamping the sleeve b; the one-way transmission mechanism includes a first circular plate 19 fixedly connected to the first gear 18, and a plurality of arc-shaped abutment plates 110 are fixedly connected to the outer wall of the first circular plate 19; a second circular plate 112 is fixedly connected to the end of the second conveying roller 111; a pressure plate 113 is connected to the second circular plate 112 by a spring, and the pressure plate 113 is provided with a protrusion that cooperates with the second circular plate 112, the protrusion being used to limit the axial displacement of the pressure plate 113 along the second circular plate 112;

[0036] During operation, the position of wire a can be manually constrained sequentially using the limiting component, and the sleeve b can be clamped and fixed using the fixing component. After the end of wire a is introduced into the sleeve b, the second cylinder 15 can be activated to control the first conveying roller 16 to descend. The first conveying roller 16 can move the second gear 181 down together, and the second gear 181 and the third gear 182 are engaged. At the same time, wire a will be tightly placed between the first conveying roller 16 and the second conveying roller 111. Then, the first cylinder 13 can be activated to drive the first rack 17 to move laterally. Here, we take the retraction of the first rack 17 controlled by the first cylinder 13 as an example. Figure 4 As shown, when the first rack 17 moves, it can mesh with the first gear 18, causing the first gear 18 to drive the first circular plate 19 to rotate. The first gear 18 rotates counterclockwise. When the first circular plate 19 rotates, the power is transmitted sequentially to the second circular plate 112, the third gear 182, and the second conveying roller 111 through the pressing engagement between the abutment plate 110 on its surface and the rectangular protrusion on the pressure plate 113. Here, the states of the second circular plate 112, the pressure plate 113, and the spring are as follows: Figure 5As shown, the spring can drive the pressure plate 113 to press against the first circular plate 19. Simultaneously, since the pressure plate 113 does not slide out of the second circular plate 112, when the abutment plate 110 applies power to the pressure plate 113, the pressure plate 113 can transmit the power to the second circular plate 112. When the third gear 182 rotates, it can mesh with the second gear 181, allowing the second gear 181 to drive the first conveying roller 16 to rotate. At this time, the first conveying roller 16 and the second conveying roller 111 can convey the wire a through rotation and friction, driving the wire a into the sleeve b. When the first cylinder 13 is activated to push the first rack 17, as... Figure 5 As shown, the first circular plate 19 can rotate in the opposite direction with the first gear 18, specifically clockwise. Due to the arc-shaped structure of the surface of the abutment plate 110, "slippage" occurs between the abutment plate 110 and the pressure plate 113. That is, the pressure plate 113 can only move laterally along the second circular plate 112 under the squeezing action of the abutment plate 110. During this process, the spring is intermittently compressed so that when the first cylinder 13 controls the first rack 17 to reciprocate, the second conveying roller 111 and the first conveying roller 16 can only perform a "forward" motion to convey the wire a. The conveying stroke of the wire a is the second conveying roller 111. The arc length of the rotation amplitude of the first conveying roller 16, taking the first gear 18 rotating one revolution when the first rack 17 is reset and the first cylinder 13 completing the push and retraction of the first rack 17 as a start-stop action, can be achieved by rhythmically controlling the opening and closing of the first cylinder 13 to realize the intermittent fixed-length threading of the wire a; by controlling the start of the first cylinder 13 through the meshing action of the first rack 17 and the first gear 18, a fixed length can be conveyed to the wire a each time, thereby making the entire threading process controllable and predictable, reducing the risk of over-threading of the wire a.

[0037] Please see Figure 6 and Figure 7 As shown, the processing side of the vertical plate 12 is equipped with a braking system; the braking system includes a third conveying roller 2 and a fourth conveying roller 22 that are rotatably arranged, with the third conveying roller 2 located above the fourth conveying roller 22; a triggering mechanism is provided at the end of the fourth conveying roller 22, and a braking actuator is provided between the fourth conveying roller 22 and the second conveying roller 111; the triggering mechanism is linked with the braking actuator, and when the wire a is disconnected from the third conveying roller 2 and the fourth conveying roller 22, the triggering mechanism brakes the second conveying roller 111 through the braking actuator;

[0038] The triggering mechanism includes a connecting block 24 fixedly disposed at the end of the fourth conveying roller 22 and a second rack 26 fixedly connected to the connecting block 24; a spring rod 23 is fixedly connected between the connecting block 24 and the top of the base 1; the braking actuation mechanism includes a fourth gear 27 rotatably connected to the vertical plate 12 and a lever 25 fixedly connected to the fourth gear 27; the fourth gear 27 and the lever 25 are eccentrically arranged; the fourth gear 27 and the second rack 26 mesh; a third rack 3 is provided on the lever 25, and a fifth gear 32 meshing with the third rack 3 is fixedly connected to the second conveying roller 111;

[0039] When the device delivers wire a, such as Figure 5 As shown, there is a gap between the fourth conveying roller 22 and the third conveying roller 2 for conveying wire a, that is, the spring rod 23 is in a compressed state, and the lever 25 is also in a deflected state. When the length of the last segment of wire a is less than the arc length of the rotation of the second conveying roller 111 and the first conveying roller 16, as shown... Figure 6 As shown, after the wire a is disconnected from the third conveyor roller 2 and the fourth conveyor roller 22, the fourth conveyor roller 22 can be reset under the elastic force of the spring rod 23. During the process, the second rack 26 can move upward with the connecting block 24 and mesh with the fourth gear 27, causing the fourth gear 27 to drive the lever 25 to deflect. When the lever 25 is reset under the meshing action of the second rack 26 and the fourth gear 27, it can cause the third rack 3 to move closer to the fifth gear 32 and mesh with the fifth gear 32, so as to forcibly brake the fifth gear 32 and the second conveyor roller 111 directly connected to it, to prevent the wire a from excessively penetrating into the sleeve b. Here, since the lever 25 and the fourth gear 27 are deflected, the slight movement of the connecting block 24 during the process... Small displacements can be amplified by lever 25 to ensure stable operation of the control components. It is worth mentioning that after lever 25 brakes the second conveying roller 111, the piston of the first cylinder 13 will also stop accordingly. Therefore, a pressure sensor should be installed at the air inlet of the first cylinder 13 to monitor the pressure in the air inlet chamber. When the pressure sensor detects that the pressure exceeds the preset safety threshold, the PLC can receive the signal sent by the pressure sensor and cut off the power supply to the solenoid valve. In addition, the tension of the wire a should be kept stable during the conveying process to avoid misjudgment by the triggering mechanism. At the same time, the airflow speed in the first cylinder 13 can be controlled by the throttle valve to slow down the conveying speed of the wire a, thereby reducing the response error caused by the power chain of the braking system.

[0040] Please see Figure 1 , Figure 8 and Figure 9 As shown, the limiting component includes at least one first fixing plate 4 fixedly disposed on the surface of the upright plate 12; the first fixing plate 4 is provided with a plurality of through slots separated by partition plate 42.

[0041] The shape of the partition 42 can be adjusted according to the number of wires a, that is, the first fixing plate 4 can be replaced as a whole. The figure shows three wires a as an example. The partition 42 can forcibly isolate adjacent wires a to reduce friction, entanglement and other situations caused by contact during the wire a threading process, thereby improving the threading quality of the device.

[0042] Please see Figure 9 As shown, a channel 5 is provided on the top of the first fixing plate 4; a plurality of sliding grooves 52 are provided on the inner wall of the first fixing plate 4; a guide wheel 53 is rotatably connected to the end of the partition plate 42, and the guide wheel 53 and the sliding groove 52 are in sliding fit; the first fixing plate 4 is also provided with a locking mechanism for locking the position of the guide wheel 53.

[0043] By setting up the channel 5 and the rotating partition 42, when the length of the wire a is short, the limiting component can be appropriately added. That is, the length between the multiple first fixing plates 4 is slightly shorter than that of the wire a. When feeding the wire a, the wire a is placed above the channel 5 of the multiple first fixing plates 4, and the wire a is put into the empty slot in the first fixing plate 4 through the channel 5. As the wire a is continuously put into the channel 5, the partition 42 can rotate and separate the wire a, which can simplify the cumbersome operation of aligning and passing the wire a through the slot in the first fixing plate 4 when feeding the wire a in the traditional way.

[0044] Please see Figure 9 As shown, the locking mechanism includes a first electromagnet 6 fixed to the bottom of the first fixed plate 4; the first fixed plate 4 has a cavity, and a locking plate 63 is slidably fitted inside the cavity; a spring is fixed between the locking plate 63 and the cavity; a magnetic core 62 is fixed to the bottom of the locking plate 63; the magnetic core 62 and the first electromagnet 6 are magnetically repelled; at least one pointer 64 is fixed to the outside of the partition plate 42, and the pointer 64 is used to position the guide wheel 53; the locking plate 63 can extend out of the cavity under the action of magnetic force and engage with the guide wheel 53.

[0045] When wire a is short, it can be fed directly from top to bottom. After feeding, the worker can observe whether the pointer 64 on the outside of the partition 42 is aligned with the center line on the first fixed plate 4. If not aligned, it can be manually adjusted. After alignment, the first electromagnet 6 can be energized. Multiple first electromagnets 6 are connected in series. When the first electromagnet 6 is energized, the magnetic core 62 can be driven by the magnetic force to push out the clamping plate 63. Figure 8 As shown, the clamping plate 63 can constrain the guide wheel 53 on the partition 42 to fix the partition 42 as a whole, which can improve the stability of the partition 42 when the wire a is transported.

[0046] Please see Figure 2As shown, the top of the connecting block 24 is provided with a second electromagnet 7, and the second electromagnet 7 and the connecting block 24 are magnetically attracted to each other; the second electromagnet 7 and the first electromagnet 6 are connected in parallel and driven by the same control circuit, and the control circuit is configured to supply power to the first electromagnet 6 and the second electromagnet 7 in a time-sharing manner.

[0047] By setting the second electromagnet 7, the third conveyor roller 2 and the fourth conveyor roller 22 are initially separated. After the operator completes the constraint of the wire a and starts the first electromagnet 6, the second electromagnet 7 can be started synchronously through the control circuit. The second electromagnet 7 can apply magnetic force to the connecting block 24, and the connecting block 24 can move upward and reduce the gap between the fourth conveyor roller 22 and the third conveyor roller 2 to only the wire a. This setting can simplify the operation of manually moving the fourth conveyor roller 22 downward when the wire a is initially loaded.

[0048] Please see Figure 1 , Figure 10 and Figure 11 As shown, the fixing assembly includes a second fixing plate 8 and a third fixing plate 82 fixedly mounted on the upright plate 12; the second fixing plate 8 is slidably provided with a plurality of first sliders 83 with support plates 84 fixed to their ends, the support plates 84 being used to support the inner wall of the sleeve b; the third fixing plate 82 is slidably provided with a plurality of second sliders 85 with arc-shaped ends, the second sliders 85 being used to clamp the outer wall of the sleeve b;

[0049] When initially fixing the sleeve b, the operator can first place the end of the sleeve b onto the support plate 84 of multiple first sliders 83. Then, the operator can control the multiple first sliders 83 to move outward and the second slider 85 to move inward. The outward movement of the first sliders 83 can pre-expand the support plate 84 on the inlet end of the sleeve b, which is convenient for the subsequent insertion of the wire a. The inward movement of the second sliders 85 can clamp the outer wall of the sleeve b, so that the sleeve b is fixed when threading the wire.

[0050] Please see Figure 11 As shown, a screw sleeve 92 is provided between the second fixing plate 8 and the third fixing plate 82, and a screw rod 9 is threadedly connected to one side of the screw sleeve 92 through an ear plate; the screw rod 9 is rotatably connected to the second fixing plate 8 and the third fixing plate 82; the screw sleeve 92 is rotatably connected to the first slider 83 and the second slider 85 through a connecting rod 93; rotating the screw rod 9 can drive the first slider 83 and the second slider 85 to move in opposite directions;

[0051] After the end of the sleeve b is pressed against the outside of the multiple support plates 84, the operator can rotate the screw 9 to drive the screw sleeve 92 to move laterally under the action of the thread transmission. When the screw sleeve 92 moves, the connecting rod 93 can coordinately control the second slider 85 and the first slider 83 on both sides, driving the second slider 85 and the first slider 83 to move in opposite directions, improving the convenience of the operator in adjusting the second slider 85 and the first slider 83.

[0052] Please see Figure 11 As shown, a crossbar 10 is fixedly connected between the second fixing plate 8 and the third fixing plate 82; the screw sleeve 92 is slidably connected to the crossbar 10 through the lug plate.

[0053] By setting a crossbar 10, which forms a sliding pair with the threaded sleeve 92, the constraint effect on the threaded sleeve 92 during thread transmission can be further improved, and the stability of the threaded sleeve 92 during movement can be improved.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
