Description

Technical Field

[0001] This invention relates to the field of transport for optical lens processing, and more specifically to a raw material transport device for optical lens processing. Background Technology

[0002] An optical lens is a light-transmitting element made of optical materials (such as glass, resin, or crystal). Its surface is usually spherical or aspherical, and it is used to refract, focus, diverge, or correct light. It is a core component of optical systems and is widely used in imaging, lighting, measurement, and communication.

[0003] The manufacturing process of optical lenses includes steps such as blank preparation, precision machining, coating and post-processing, inspection and packaging. Among them, the blank of optical lenses refers to the semi-finished material used to process optical lenses, which is usually glass or resin blank that has not been ground, polished and coated.

[0004] For resin-based optical lens blanks, efficient transportation is essential to ensure a smooth production process before they enter the precision machining stage. However, traditional transportation methods are inefficient and reliant on manual labor, especially in the unloading stage, where blanks often need to be removed manually one by one. This not only increases labor costs but also reduces transportation efficiency.

[0005] Based on the above problems, there is an urgent need for a blank transport device for optical lens processing to optimize the unloading steps, achieve the effect of automatically pushing out the blank, make it easier for workers to pick up, and thus optimize the operation process. Summary of the Invention

A pressure rod is fixedly connected to the bottom of the pedal, the pressure rod passing through the transport vehicle from bottom to top and being built into the guide post. The upper end of the pressure rod extends out of the guide post and beyond the top of the rotating frame. Two symmetrically distributed L-shaped rods are fixedly connected to the top of the pressure rod. Two symmetrically distributed fixing frames are keyed to the top of the guide post. The fixing frames correspond one-to-one with the L-shaped rods. One end of each fixing frame is fixedly connected to a telescopic component II. The telescopic ends of the two telescopic components II are jointly fixedly connected to a pushing frame. A return spring is provided between the pushing frame and the telescopic component II.

[0011] Preferably, an annular guide frame is fixed to the top surface of the lifting plate, and the rotating frame is rotatably connected to the annular top surface of the guide frame. Two symmetrically distributed rotating rods are rotatably connected to the transport vehicle. The ends of the two rotating rods penetrate the lifting plate and are fixed to the side wall of the rotating frame. A gear ring is connected through and keyed to both rotating rods. A straight column is rotatably connected to the transport vehicle. A one-way gear is keyed to the top of the straight column. The one-way gear meshes with the gear ring. Turntables are keyed to both the upper and lower ends of the one-way gear. The two turntables are respectively pressed against the upper and lower sides of the meshing area between the one-way gear and the gear ring. A threaded section is provided in the middle of the straight column, and the upper and lower ends of the straight column are smooth sections. The end of the pedal is rotatably connected to the straight column.

[0012] Preferably, the receiving frame is provided with a placement cavity for placing the blank, and the side wall of the receiving frame is connected to a flip cover that covers the top of the blank and stabilizes the blank in the placement cavity, and a torsion spring is provided between the flip cover and the receiving frame.

[0013] Preferably, the upper surface of each rotating frame except the top layer is provided with evenly distributed placement units, and each placement unit is slidably connected with a receiving frame. The lower surface of each rotating frame except the bottom layer is fixed with a pressing member corresponding to each placement unit, and the pressing member is pressed into contact with the top surface of the flip cover.

[0014] Preferably, each of the receiving frames is fixed with two sets of symmetrically distributed limiting block groups at the top. Each limiting block group consists of two fixing blocks with through holes arranged front and rear. Two magnetic suction devices are installed on the top of the receiving frame. The two magnetic suction devices are distributed one-to-one with the two sets of limiting block groups and are located on the front side of the limiting block groups. Two magnets corresponding to the limiting block groups are fixed to the end of the pushing frame.

[0015] Preferably, each rotating frame except the top layer has multiple pins fixed to its top. The pins are symmetrically distributed on the left and right sides of each receiving frame. Each pin has a T-shaped pressing member slidably connected to it. A pressure spring is provided between the T-shaped pressing member and the rotating frame and is wound around the adjacent pin.

[0017] Beneficial effects: Compared with existing technologies, this device, through the adjustment of the lifting plate, pedal, one-way gear, and gear ring, gradually positions the receiving frame containing the blank material onto a working plane flush with the pusher frame. The pusher assembly then pushes the frame, automatically ejecting the receiving frame, making it easier for workers to handle and thus optimizing the unloading process. The cooperation between the pressing component and the top of the flip cover stabilizes the blank material within the receiving frame, ensuring stability during transport. The cooperation of the shielding component, shielding curtain, and winding assembly enables the winding and unfolding of the shielding curtain. When the curtain is rolled up, it facilitates the use of the device; when unfolded, it covers and protects the internal components, achieving equipment enclosure and protection.

Detailed Implementation

[0025] Next, combine Figures 1-6 A specific embodiment of the present invention will be described in detail below.

[0026] refer to Figure 1 and Figure 6 An optical lens processing blank transport device includes a freely movable transport vehicle 1 for transferring blanks to a designated workstation. A controlled lifting plate 12 is slidably mounted on the transport vehicle 1. The lifting plate 12 is equipped with a multi-layered rotating frame 14 with controlled rotation. Multiple rotating frames 14 are stacked and layered vertically in a disassembly manner to form a multi-level blank bearing structure, which can flexibly adjust the number of layers according to actual loading requirements. The rotating frame 14 is equipped with uniformly distributed placement units 15. Each placement unit 15 has a receiving frame 3 for carrying blanks slidably mounted inside. The transport vehicle 1 is equipped with a controlled-moving pushing component. The pushing component acts on the receiving frame 3 and can push out the receiving frame 3 along with the blanks loaded inside it during the unloading stage to achieve automatic unloading.

[0027] Initially, the blank is placed in the receiving frame 3 of the placement unit 15 on the rotating frame 14. Multiple rotating frames 14 are stacked layer by layer in the vertical direction and fixed by disassembly and connection structure to form an integrated multi-level rotating frame 14. After loading, the mobile transport vehicle 1 is moved to the target processing station.

[0028] During the unloading stage, the lifting plate 12 is raised and lowered to elevate the rotating frame 14, placement unit 15, and receiving frame 3 containing the blanks to a suitable working height for manual material handling. Then, the pushing component is activated to automatically push the receiving frame 3 and the blanks inside it out of the transport vehicle 1, making it easy for operators to pick up the materials directly and in an orderly manner, significantly improving material handover efficiency, reducing manual intervention, and optimizing the work process.

[0029] refer to Figure 2 , Figure 3 , Figure 4 The pushing assembly includes a pedal 2 slidably attached to one side of the transport vehicle 1. A compression spring 21 is provided between the pedal 2 and the transport vehicle 1 to provide automatic restoring force after being stepped on. A hollow guide post 25 is fixedly connected to the top axis of the transport vehicle 1. The guide post 25 passes through the axis of the lifting plate 12 and the rotating frame 14 and extends upward. A pressure rod 26 is fixedly connected to the bottom of the pedal 2. The pressure rod 26 passes through the transport vehicle 1 from bottom to top and is built into the guide post 25. The upper end of the pressure rod 26 extends out of the guide post 25 and beyond the top of the rotating frame 14.

[0030] refer to Figure 3 The top of the pressure rod 26 is fixed with two symmetrically distributed L-shaped rods 273, which move with the pressure rod 26. The top of the guide post 25 is keyed with two symmetrically distributed fixing frames 27, which correspond one-to-one with the L-shaped rods 273. One end of each fixing frame 27 is fixed with a telescopic member 28. The telescopic ends of the two telescopic members 28 are jointly fixed with a push frame 210. A return spring 29 is provided between the push frame 210 and the telescopic member 28. The return spring 29 is wound around the telescopic end of the adjacent telescopic member 28 to provide a return base for the push frame 210.

[0031] refer to Figure 3 The height of the pusher 210 is optimized and positioned at an ergonomic height that facilitates the operator's handling of the blank. The ejection of the blank depends on the directional movement of the pusher 210. Therefore, the device is designed with the following linkage: each fixed frame 27 is hinged to a connecting rod 271 at the end away from the telescopic member 28. Each connecting rod 271 is hinged to a connecting rod 272. The ends of the connecting rods 272 are hinged to one side of the pusher 210. The L-shaped rod 273 compresses the hinge point of the connecting rods 271 and 272, thereby realizing the movement of the connecting rods 271 and 272, and ultimately causing the pusher 210 to push.

[0032] As described above, after the material is loaded, the blank is stably placed in the receiving frame 3. The transport vehicle 1 is moved to the target work position, and the lifting plate 12 is adjusted to raise the rotating frame 14, the placement unit 15 and the receiving frame 3 loaded with the blank to a working height suitable for manual material handling. That is, the receiving frame 3 of the target layer on the rotating frame 14 and the push end of the push frame 210 are at the same working height.

[0033] Subsequently, the external force lowers the pedal 2, compresses the spring 21, and moves the pressure rod 26 downward. The two L-shaped rods 273 fixed at its top are controlled to move downward synchronously. The downward movement of the L-shaped rods 273 applies downward squeezing force to the hinge point of the adjacent connecting rod 1 271 and connecting rod 272. Based on the presence of connecting rod 1 271 and connecting rod 272, the push frame 210 is controlled to move outward horizontally. The telescopic end of the telescopic component 28 extends, the return spring 29 deforms, and the push frame 210 acts on the side of the receiving frame 3 of the target layer on the rotating frame 14, pushing the receiving frame 3 and the blank loaded inside it out of the transport vehicle 1 as a whole. This makes it convenient and safe for operators to pick up the blanks at an appropriate height, thus completing efficient unloading.

[0034] After releasing pedal 2, pedal 2 and push frame 210 automatically reset under the action of compression spring 21 and return spring 29, and the device returns to standby state, ready for the next operation.

[0035] To ensure the precise ejection of the target layer receiving frame 3 from the pusher frame 210 onto the rotating frame 14, the receiving frame 3 must be positioned at a preset height flush with the working end of the pusher frame 210 before unloading. This positioning is achieved through the controllable lifting and lowering of the lifting plate 12.

[0036] refer to Figure 6 Therefore, the transport vehicle 1 is equipped with an electric push rod 11, the output end of which is connected to the bottom key of the lifting plate 12, in order to provide stable and controllable lifting power for the lifting plate 12.

[0037] During the feeding stage, the electric push rod 11 is activated to drive the lifting plate 12 and the rotating frame 14 connected to it, as well as the placement units 15 and the receiving frame 3 of each layer, to move down synchronously until they reach a low position that is easy for manual operation, and then the blanks are loaded.

[0038] After the billet is loaded, the unloading stage begins. The electric push rod 11 is started again to drive the lifting plate 12 and the rotating frame 14 connected to it, as well as the placement units 15 and the receiving frame 3 of each layer, to move upward synchronously. The stroke of the electric push rod 11 is adjusted through relevant programs to lift the receiving frame 3 of the target layer in the rotating frame 14 to the working height that matches the push end of the push frame 210, thus completing the precise positioning and preparing for the subsequent automatic push-out operation.

[0039] refer to Figure 6To enable workers to efficiently and precisely load materials onto each layer of the rotating frame 14 at fixed positions, thereby improving the overall loading efficiency, the rotating frame 14 is equipped with a controlled rotation function. The specific control method is as follows: the top surface of the lifting plate 12 is fixedly connected to an annular guide frame 13, and the rotating frame 14 is rotated onto the annular top surface of the guide frame 13, which aims to provide stable rotation support and guidance.

[0040] refer to Figure 2 and Figure 6 The transport vehicle 1 is equipped with two symmetrically distributed rotating rods 241. The ends of the two rotating rods 241 pass through the lifting plate 12 and are fixed to the side wall of the rotating frame 14. A gear ring 24 passes through and is keyed to both rotating rods 241. The gear ring 24 is centered between the lifting plate 12 and the rotating frame 14. The rotation of the rotating frame 14 is driven by the rotation of the gear ring 24.

[0041] refer to Figure 2 and Figure 4 To achieve the rotation of the gear ring 24, the following design is made: a straight column 22 is connected to the transport vehicle 1, and a one-way gear 23 is keyed to the top of the straight column 22. The one-way gear 23 meshes with the gear ring 24. Turntables are keyed to both the upper and lower ends of the one-way gear 23. The two turntables are respectively pressed against the upper and lower sides of the meshing area between the one-way gear 23 and the gear ring 24, so that the meshing is stable and the teeth do not disengage during the transmission process.

[0042] The rotation of the gear ring 24 depends on the rotation of the one-way gear 23, and the rotation of the one-way gear 23 depends on the rotation of the straight column 22. In order to avoid setting up an additional independent power source, this device uses the pressing action of the pedal 2 to achieve linkage drive.

[0043] refer to Figure 2 The straight column 22 has a threaded section 221 in the middle, that is, the upper and lower ends of the straight column 22 are smooth sections, and the middle part is a threaded section 221. The end of the pedal 2 is connected to the straight column 22. Initially, the end of the pedal 2 is connected to the smooth section at the top of the straight column 22. At this time, stepping on it only drives the pressure rod 26 to move downward, and the straight column 22 does not rotate.

[0044] Lower pedal 2, the end of pedal 2 gradually moves down, when the end of pedal 2 is at the smooth section at the top of straight column 22, straight column 22 does not rotate, one-way gear 23 and gear ring 24 do not mesh, lifting plate 12 and the components on it gradually move up and are lifted.

[0045] As the pedal 2 gradually moves down, the end of the pedal 2 moves to the threaded section 221, and the straight column 22 is rotated in a controlled manner. At this time, the one-way gear 23 is rotated in a controlled manner. The one-way gear 23 meshes with the gear ring 24, and the gear ring 24 rotates. Then the rotating rod 241 is rotated in a controlled manner. The rotating rod 241 drives the rotating frame 14 and its various layer placement units 15 and receiving frame 3 to rotate synchronously, so that the receiving frames 3 of different layers rotate to the preset feeding position in sequence, realizing fixed-point continuous feeding.

[0046] As the pedal 2 continues to move downward, the end of the pedal 2 disengages from the threaded section 221 and eventually moves to the smooth section at the bottom of the straight column 22. At this point, the straight column 22 stops rotating, and the one-way gear 23 and the gear ring 24 do not mesh. The purpose is to stop the rotating frame 14 from rotating, and the receiving frame 3 and its internal blank are positioned, preparing for the subsequent lifting to the unloading height and the execution of the automatic ejection operation.

[0047] When pedal 2 is pressed down to the end of its stroke and stops, the receiving frame 3 of the target layer is precisely positioned. At the same time, the pressure rod 26 linked with pedal 2 also reaches its lower limit of movement, and the L-shaped rod 273 fixed at its top moves down to the predetermined position, applying a downward squeezing force to the hinge point of the adjacent connecting rod 1 271 and connecting rod 272, driving the pusher frame 210 to push outward in the horizontal direction, acting on the side of the positioned target layer receiving frame 3, pushing it out of the transport vehicle 1 along with the internal blank, thus realizing automated material pushing operation.

[0048] After unloading is completed, the pedal 2 is released and then moved upward to reset under the action of the compression spring 21. That is, the end of the pedal 2 moves along the path of the smooth section at the bottom of the straight column 22, the threaded section 221, and the smooth section at the top of the straight column 22. Based on the design of the one-way gear 23, the one-way gear 23 does not mesh with the gear ring 24 during the upward movement of the pedal 2. The rotating frame 14 does not rotate during this stage, and the rotating frame 14, the receiving frame 3 and the blank inside it continue to maintain the positioning state.

[0049] Under the action of the return spring 29, the push frame 210 automatically resets, and the device returns to the standby state, ready for the next operation.

[0050] Subsequently, the pedal 2 is depressed again. The pedal 2 moves along the path of the smooth section at the top of the straight column 22, the threaded section 221, and the smooth section at the bottom of the straight column 22, so that the one-way gear 23 and the gear ring 24 mesh again. During this stage, the rotating frame 14 rotates again, and the rotating frame 14, the receiving frame 3 and the blank inside it are switched. That is, the receiving frame 3 with the blank removed is moved by the rotation of the rotating frame 14, and the receiving frame 3 with the blank is filled by the rotation of the rotating frame 14.

[0051] At this time, the L-shaped rod 273 of the pressure rod 26 linked to the pedal 2 moves down to the predetermined position. Under the action of the first connecting rod 271 and the second connecting rod 272, the drive push frame 210 is pushed outward again in the horizontal direction, acting on the side of the already positioned target layer receiving frame 3, pushing it out of the transport vehicle 1 along with the internal blank, thus realizing continuous automated material pushing operation.

[0052] By adjusting the electric push rod 11, each layer of the receiving frame 3 of the rotating frame 14 is sequentially raised to the unloading height level with the working end of the push frame 210. Subsequently, the operation of stepping on the pedal 2 is performed cyclically to achieve continuous and automated material pushing operation of each layer of the receiving frame 3 of the rotating frame 14.

[0053] After the material is loaded, in order to ensure that the optical lens blank is stably fixed in the receiving frame 3 during transportation and automatically released during the pushing process after arriving at the target station, so as to facilitate convenient use by the operator, the following design is made.

[0054] refer to Figure 3 and Figure 5 The receiving frame 3 is provided with a placement cavity for placing the blank. The side wall of the receiving frame 3 is connected to a flip cover 32 that covers the top of the blank and stabilizes the blank in the placement cavity. A torsion spring 33 is provided between the flip cover 32 and the receiving frame 3. The torsion spring 33 causes the flip cover 32 to rotate and open automatically.

[0055] To ensure the stability of the raw material during transportation, the flip cover 32 needs to overcome the torque force of the torsion spring 33 and press against the receiving frame 3. Except for the top layer, the upper surface of each rotating frame 14 is provided with evenly distributed placement units 15. Each placement unit 15 has a receiving frame 3 slidably connected inside. Except for the bottom layer, the lower surface of each rotating frame 14 is fixed with a pressing member 35 corresponding to the placement unit 15. The pressing member 35 is pressed against the top surface of the flip cover 32, so that the flip cover 32 overcomes the torque force of the torsion spring 33 and presses against the receiving frame 3.

[0056] During the feeding stage, the blank is pre-placed in the receiving frame 3 of the placement unit 15 on each layer of rotating frame 14. As multiple rotating frames 14 are stacked layer by layer in the vertical direction, the pressing part 35 of each layer of rotating frame 14 presses down vertically on the top surface of the flip cover 32 on the lower layer of receiving frame 3 as it is installed in place, driving the flip cover 32 to rotate around its axis and close, thereby covering and limiting the blank in the receiving frame 3.

[0057] The detachable connection structure between the rotating frames 14 enables stable assembly between each layer. At the same time, with the help of the pressing component 35 to close the flip cover 32, the overall assembly and loading operation of the multi-level rotating frames 14 is completed, ensuring the stability and safety of the blanks during transportation.

[0058] refer to Figure 5To achieve precise positioning and stable pushing of the receiving frame 3 by the pushing frame 210 during the material pushing process, this device is equipped with limiting components. Each receiving frame 3 has two symmetrically distributed limiting block groups 31 fixed to its top. Each limiting block group 31 consists of two fixed blocks with through holes arranged front and rear. Two magnetic suction devices 311 are installed on the top of the receiving frame 3, corresponding one-to-one with the two limiting block groups 31 and located on the front side of the limiting block groups 31. The ends of the pushing frame 210 are fixed with two... The magnets 211 distributed in the block group 31 are designed to pass through the through holes of the fixing blocks in the corresponding limiting block group 31 in sequence when the push frame 210 moves horizontally during the pushing process, and generate magnetic attraction with the magnetic attraction 311 on the receiving frame 3, so as to realize the automatic centering and fixing between the two. Through the guiding effect of the through holes of the limiting block group 31 and the synergistic effect of magnetic attraction, the push frame 210 and the target receiving frame 3 are accurately aligned, which enhances the stability of the pushing process, prevents off-center loading or slippage, and effectively improves the reliability of automatic pushing.

[0059] refer to Figure 5 To achieve the automatic reset function of the receiving frame 3 after the material is pushed, multiple pins 38 are fixed to the top of each rotating frame 14 except the top layer. The pins 38 are symmetrically distributed on the left and right sides of each receiving frame 3. A T-shaped pressing member 37 is slidably connected to each pin 38. A pressure spring 34 is provided between the T-shaped pressing member 37 and the rotating frame 14 and is wound around the adjacent pin 38, which is intended to provide a reset basis for the T-shaped pressing member 37.

[0060] Each set of limiting block groups 31 has a support column 312 fixedly connected to the side away from the receiving frame 3. The T-shaped pressing member 37 has a connecting rod 36 hinged to the side near the support column 312. As the push frame 210 moves, the magnet 211 passes through the through hole of the fixed block in the corresponding limiting block group 31 in sequence, and generates a magnetic attraction with the magnetic attraction 311 on the receiving frame 3, thereby pushing the receiving frame 3 outward as a whole. As the receiving frame 3 moves, the support column 312 moves synchronously. The movement of the support column 312 and the pressing engagement of the connecting rod 36 cause the T-shaped pressing member 37 to move downward in a controlled manner. The pressure spring 34 deforms, and the downward movement of the T-shaped pressing member 37 serves as a movement avoidance for the support column 312.

[0061] As the receiving frame 3 is gradually pushed out, the pressing component 35 gradually cancels its pressing effect on the flip cover 32. Under the action of the torsion spring 33, the flip cover 32 automatically flips open, thereby realizing automatic opening and facilitating material retrieval.

[0062] When the pusher 210 moves in the reverse direction to reset, the magnet 211 disengages from the magnetic attraction 311, and the pusher 210 no longer exerts a pushing force on the receiving frame 3. Under the action of the pressure spring 34, the T-shaped lower pressing member 37 moves upward, and through the connecting rod 36, it drives the support column 312 to move in the reverse direction, thereby pushing the receiving frame 3 to automatically slide back to the initial position along the original path, completing the reset. During the reset process of the receiving frame 3, the pressing member 35 applies a downward pressing force to the flip cover 32 again, overcoming the elastic force of the torsion spring 33, so that the flip cover 32 closes and locks again, preparing for the next transport or loading.

[0063] refer to Figure 6 To achieve dustproof performance when the device is not in use and effectively prevent dust accumulation on the surface of components, the following design is made: a shielding component 4 is detachably installed on the top of the rotating frame 14 at the top layer. A shielding curtain 46 is installed on the shielding component 4. The shielding curtain 46 unfolds and covers downwards, completely enclosing the external structure of the device to form a closed protection, thereby effectively isolating dust in the environment and keeping the internal components clean.

[0064] For ease of use, this device has a winding assembly at the top of the shielding member 4 to roll up the shielding curtain 46. A rotating disk 42 is rotatably connected to the top axis of the shielding member 4. A rotating handle 48 for easy external force drive is keyed to the top of the rotating disk 42. Two symmetrically distributed short columns 45 are fixed to the side wall of the rotating disk 42. Two symmetrically distributed positioning columns 47 are fixed to the top of the shielding member 4. The two positioning columns 47 are distributed on the left and right sides of the rotating disk 42. A rotating ring 44 is slidably connected to the two positioning columns 47. The rotating ring 44 has evenly distributed teeth 441. Each tooth 441 has an inclined surface. A storage spring 43 is wound around the positioning column 47 between the rotating ring 44 and the top of the shielding member 4. The positioning column 47 and the inclined surface of the tooth 441 are pressed together.

[0065] A pull rope 41 is wound around the rotating disk 42, and the two free ends of the pull rope 41 are fixed to the left and right ends of the bottom of the curtain 46, respectively.

[0066] In use, rotating the handle 48 drives the rotating disk 42 to rotate synchronously, the pull rope 41 gradually retracts, and the shielding curtain 46 is controlled to roll upward, exposing the components of the device for easy operation and maintenance.

[0067] As the rotating disk 42 rotates, the short column 45 rotates under control. The rotation of the short column 45 engages with the inclined surface on the tooth 441, and the tooth 441 is pressed to drive the rotating ring 44 to move downward as a whole. The energy storage spring 43 deforms. Based on the inclined surface design of the tooth 441, when the handle 48 rotates in the forward direction, the short column 45 can push the inclined surface of the tooth 441 and drive the rotating ring 44 to move downward. When the handle 48 stops rotating or reverses, the short column 45 abuts against the non-inclined side of the tooth 441, forming a mechanical interlock, thereby realizing the automatic locking of the pull rope 41 winding action and keeping the curtain 46 in the winding state.

[0068] When the device is not in use, manually press down the rotating ring 44 to disengage the tooth 441 from the mechanical lock of the short column 45. Then reverse the handle 48, the rotating disk 42 reverses, the pull rope 41 loosens, and the shielding curtain 46 unfolds downward to cover and protect the internal components of the device, thus achieving the enclosure and protection of the equipment.

[0069] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
