[0076] This embodiment provides a cigarette box opening system, such as Figure 1 As shown, along the conveying direction of the cigarette box, it includes a center seam cutting device 1, an upper cover opening device 2, a lower cover opening device 3, an upper and lower cover flipping device 4 and a cigarette pushing device 5 which are arranged in sequence. The center seam cutting device 1 is used to cut the tape on the cigarette box from the middle, the upper cover opening device 2 is used to suck up a gap in the upper cover, and then cut the bonded tape at the upper cover flange, so that the upper cover and the tape are completely separated, the lower cover opening device 3 is used to suck up a gap in the lower cover, and then cut the bonded tape at the lower cover flange, so that the lower cover and the tape are completely separated, the upper and lower cover flipping device 4 is used to flip the upper and lower covers to an open state, and the cigarette pushing device 5 is used to push the cigarettes from the cigarette box to the next process.

[0077] like Figure 2-Figure 4As shown, the center seam device 1 includes a first conveying unit 1-1, which is used to convey the cigarette box along a first direction. The first conveying unit 1-1 adopts a powered roller conveyor line or a belt transmission mechanism, etc. Those skilled in the art can set it according to actual needs. In this embodiment, the first conveying unit 1-1 adopts a first powered roller conveyor line.

[0078] like Figure 5-Figure 6 As shown, the first conveying unit 1-1 is provided with two blocking mechanisms 1-2 on the conveying path for blocking the movement of the cigarette box. The blocking mechanism 1-2 includes a blocking member connected to a lifting element to block the cigarette box.

[0079] like Figure 7-Figure 8 As shown, in this embodiment, the blocking member adopts a blocking plate 1-2-1, and the lifting element adopts a lifting cylinder 1-2-2. The lifting cylinder 1-2-2 is fixed on the frame of the first conveying unit, and the piston rod of the lifting cylinder 1-2-2 is connected to the blocking plate 1-2-1. The blocking plate 1-2-1 can extend through the gap between adjacent power rollers to above the power roller conveyor line to block the cigarette box.

[0080] Furthermore, the blocking plate 1-2-1 is provided with a guide shaft 1-2-3, and the guide shaft 1-2-3 passes through the linear bearing 1-2-4 provided on the frame of the conveying unit and is slidably connected to the linear bearing to guide the lifting movement of the blocking plate.

[0081] Photoelectric detection elements 1-3 are also provided at set positions on both sides of the first conveying unit frame to detect whether the cigarette box is in place on the first conveying unit 1-1. When the photoelectric detection element 1-3 detects that the cigarette box is in place, the first conveying unit 1-1 stops working, and at the same time the lifting cylinder 1-2-2 drives the blocking plate 1-2-1 to rise to block the cigarette box.

[0082] A centering base 1-4 is provided on both sides of the first conveying unit 1-1. The centering base 1-4 is connected to a first bidirectional driving mechanism. The first bidirectional driving mechanism can drive the two centering bases 1-4 to move toward or away from each other synchronously, and the movement direction is perpendicular to the first direction.

[0083] In this embodiment, the centering base 1-4 is slidably connected to a guide rail 1-6 installed at the bottom of the centering device frame 1-5 to guide the movement of the centering base 1-4.

[0084] The first bidirectional driving mechanism includes a first cylinder 1-7, which is arranged along a second direction perpendicular to the first direction. The cylinder body of the first cylinder 1-7 is connected to the centering device frame 1-5, and its piston rod is connected to the centering base 1-4 on one side. The two centering bases 1-4 are both connected to the synchronous belt mechanism 1-8 installed at the bottom of the centering device frame 1-5, and the two centering bases 1-4 are respectively connected to the two parts of the synchronous belt with opposite movement directions. The first cylinder 1-7 can drive one of the centering bases 1-4 to move, and through the transmission action of the synchronous belt, the two centering bases 1-4 are able to make synchronous movements toward or away from each other.

[0085] Centering bases 1-4 on both sides are equipped with centering mechanisms.

[0086] The center seam cutting mechanism includes a telescopic component, a parallelogram connecting rod mechanism, a smoke pressing plate and a blade.

[0087] In this embodiment, the telescopic structure adopts a smoke compression cylinder 1-9, the cylinder body of the smoke compression cylinder 1-9 is hinged to the centering base 1-4, and its piston rod is hinged to the vertical rod 1-10 on one side of the parallelogram linkage mechanism through a Y-type joint 1-12. The Y-type joint can use an existing joint and will not be described in detail here. The bottom ends of the vertical rods 1-10 on both sides are hinged to the centering base 1-4, and the upper cross bar is hinged between the top ends of the vertical rods 1-10 on both sides, and the middle cross bar 1-11 is also hinged between the middle parts of the vertical rods 1-10 on both sides. A telescopic driving member is installed on the middle cross bar, and the telescopic driving member adopts a blade cylinder 1-13. The blade cylinder 1-13 is set along the second direction, and the cylinder body of the blade cylinder 1-13 is fixed to the middle cross bar 1-11, and its piston rod is connected to the blade 1-14 through the blade seat 1-15. The upper cross bar is provided with a cigarette pressing plate 1-16, which is used to contact the top surface of the cigarette box to apply pressure to the cigarette box.

[0088] A cigarette moving mechanism is also provided above the first conveying unit 1-1. Figure 9 As shown, the cigarette plucking mechanism includes a cigarette plucking plate conveying mechanism 1-17 provided above the first conveying unit. The conveying direction of the cigarette plucking plate conveying mechanism 1-17 is parallel to the conveying direction of the first conveying unit 1-1. The cigarette plucking plate conveying mechanism 1-17 is connected to a cigarette plucking plate 1-18. The cigarette plucking plate 1-18 rotates unidirectionally on the cigarette plucking plate conveying mechanism 1-17 so that the cigarette plucking plate can only rotate toward the smoke outlet side of the first conveying unit 1-1.

[0089] In this embodiment, the cigarette prying plate conveying mechanism adopts a rodless cylinder 1-17-1 fixed on the upper part of the center seam device frame, the rodless cylinder 1-17-1 is connected to the slider 1-17-2, the slider 1-17-2 is slidably connected to the guide shaft 1-17-3 fixed to the center seam device frame, and can move in a first direction. The slider is rotatably connected to the cigarette prying plate. Along the conveying direction of the cigarette box, a limit plate is provided on the rear side of the cigarette prying plate, so that the cigarette prying plate can only rotate toward the front along the conveying direction and not toward the rear.

[0090] The working principle of the mid-slit scoring device of this embodiment is as follows:

[0091] The first conveying unit 1-1 conveys the cigarette box, and the cigarette moving plate 1-18 rotates to allow the cigarette box to pass. When the photoelectric detection element 1-3 detects that the cigarette box is in place, the first conveying unit 1-1 stops working, and the two blocking plates 1-2-1 rise to block the cigarette box.

[0092] The first bidirectional driving mechanism drives the two centering bases 1 - 4 to move toward each other, contact the two side surfaces of the cigarette box, and center the cigarette box.

[0093] The smoke pressing cylinder 1-9 works, driving the smoke pressing plate 1-16 to press on the upper surface of the cigarette box, and at the same time the blade cylinder 1-13 extends out, and the blade 1-14 contacts the middle position of the tape.

[0094] The rodless cylinder 1-17-1 works to drive the cigarette plucking plate 1-18 to move. Since the cigarette plucking plate 1-18 can only rotate in one direction, the cigarette plucking plate 1-18 pushes the cigarette box forward and the blade 1-14 cuts the tape.

[0095] After the cigarette box leaves the first conveying unit 1 - 1 , the blocking mechanism, the centering mechanism, the centering base and other structures are reset.

[0096] like Figure 10-14 As shown, the upper cover opening device 2 includes a second conveying unit 2-1, and the second conveying unit 2-1 is used to receive the cigarette box delivered by the first conveying unit 1-1.

[0097] The second conveying unit 2 - 1 adopts a powered roller conveyor line or a belt transmission mechanism, preferably adopts the existing second powered roller conveyor line.

[0098] like Figure 15-17 As shown, a blocking mechanism 2-2 is provided at a setting position on the discharge side of the second conveying unit 2-1. The blocking mechanism 2-2 adopts a blocking plate, which is connected to the piston rod of the lifting cylinder. The lifting cylinder is installed on the second conveying unit frame. A photoelectric detection element 2-3 installed on the second conveying unit frame is provided in front of the blocking plate to detect the position of the cigarette box in the second conveying unit.

[0099] A movable base 2-4 is provided on both sides of the second conveying unit 2-1. The movable base 2-4 is slidably connected to the upper cover opening device frame 2-5 through the guide rail at the bottom of the upper cover opening device frame 2-5. The movable bases 2-4 on both sides can move toward or away from each other synchronously along the second direction.

[0100] like Figure 18-19 As shown, the two mobile bases 2-4 are connected to a second bidirectional driving mechanism, which can drive the two mobile bases to move toward or away from each other synchronously.

[0101] The second bidirectional drive mechanism has the same structure as the first bidirectional drive mechanism, and includes a second cylinder 2-17. One end of the second cylinder 2-17 is connected to the upper cover opening device frame 2-5, and the other end is connected to the movable base 2-4 on one side. The two movable bases 2-4 are respectively connected to the parts of the synchronous belt mechanism with opposite movement directions. The synchronous belt mechanism is installed at the bottom of the upper cover opening device frame 2-5.

[0102] The portion of the upper cover opening device frame 2-5 connected to the second bidirectional driving mechanism is connected to the remaining portion of the upper cover opening device frame 2-5 via a lifting cylinder to achieve the lifting of the movable base 2-4.

[0103] A first cigarette sorting plate 2-6 is installed on the movable base 2-4, and the first cigarette sorting plate 2-6 is used to contact the lower cover of the cigarette box.

[0104] Two first suction cups 2-7 are provided above the first cigarette sorting plate 2-6. The first suction cup 2-7 is connected to the first suction cup driving component. The first suction cup driving component adopts a first suction cup cylinder 2-8 arranged along the second direction. The cylinder body of the first suction cup cylinder 2-8 is connected to the movable base 2-4, and its piston rod is connected to the first suction cup 2-7. The first suction cup 2-7 is connected to the vacuum generator 2-9 installed on the movable base.

[0105] Two first cutters 2-10 are provided on the outer side of the first cigarette sorting plate 2-6. The first cutters 2-10 are connected to the cutter lifting member. The cutter lifting member adopts a cutter lifting cylinder 2-11. The cutter lifting cylinder 2-11 is installed on the cutter seat. The two cutter seats are slidably connected to the guide rail installed on the mobile base and arranged along the first direction. The cutter seat is connected to the third bidirectional drive mechanism. The third bidirectional drive mechanism drives the two first cutters to move toward or away from each other synchronously along the first direction.

[0106] The third bidirectional drive mechanism includes a third cylinder 2-12, the cylinder body of the third cylinder 2-12 is connected to the movable base 2-4, the piston rod of the third cylinder 2-12 is connected to a cutter seat, the two cutter seats are respectively connected to the two parts of the synchronous belt of the synchronous belt mechanism 2-13 with opposite movement directions, and the synchronous belt mechanism 2-13 is installed on the movable base 2-4.

[0107] The first suction cup 2-7, the first cutter 2-10, the third bidirectional driving mechanism, and the cutter lifting cylinder 2-11 together constitute the upper cover opening mechanism.

[0108] A box pressing mechanism 2-14 is also provided above the second conveying unit. The box pressing mechanism 2-14 is installed on the top of the upper cover opening device frame 2-5. The box pressing mechanism 2-14 is connected to the box pressing plate 2-15 and can drive the box pressing plate 2-15 to move up and down. The box pressing plate 2-15 is used to cooperate with the upper surface of the cigarette box.

[0109] The box pressing mechanism can adopt existing technology, and its specific structure will not be described in detail here.

[0110] like Figure 20-22 As shown, the pressure box plate 2-15 passes through a spring telescopic rod 2-16, and the spring telescopic rod 2-16 includes a fixed tube, which is fixed to a tube seat, and the tube seat is fixed to the upper surface of the pressure box plate. The fixed tube is telescopically connected with a telescopic rod, and a spring is provided between the telescopic rod and the fixed tube. The bottom end of the telescopic rod is used to contact the upper surface of the smoke box, and the top end of the telescopic rod is provided with a detection piece 2-20. Correspondingly, the upper surface of the pressure box plate 2-15 is provided with a bracket, and the bracket is provided with a smoke compression stop photoelectric detection element 2-18 and a smoke compression deceleration photoelectric detection element 2-19 distributed up and down.

[0111] After the spring telescopic rod 2-16 contacts the cigarette box, the spring force is overcome, and the box pressing plate 2-15 continues to move downward. When the detection piece 2-20 cooperates with the smoke compression deceleration photoelectric detection element 2-19, the box pressing mechanism begins to decelerate. When the detection piece cooperates with the smoke compression stop photoelectric detection element 2-18, the box pressing mechanism stops moving. At this time, the box pressing plate contacts the top surface of the cigarette box.

[0112] This setting method can apply pressure to smoke boxes of different heights to achieve box pressing operation, thereby improving applicability.

[0113] The working principle of the upper opening device of this embodiment is as follows:

[0114] The second conveying unit 2-1 drives the cigarette box to move. When the photoelectric detection element 2-3 detects that the cigarette box is in place, the second transmission unit 2-1 stops moving and the blocking plate rises to block the movement of the cigarette box.

[0115] The second bidirectional driving mechanism drives the movable base 2-4 to move toward each other, and the cigarette box is centered through the first cigarette sorting plate 2-6, and then the second bidirectional driving mechanism drives the movable base 2-4 to move away from each other.

[0116] The box pressing mechanism 2-14 works, driving the box pressing plate 2-15 to press the cigarette box, and then the second bidirectional driving mechanism drives the first cigarette sorting plate 2-6 to press the lower cover.

[0117] The first suction cup cylinder 2-8 extends, and after the first suction cup 2-7 absorbs the upper cover, the first suction cup cylinder 2-8 retracts, sucking a gap in the upper cover.

[0118] The two first cutters 2-10 rise simultaneously and move away from each other after the rise is completed, cutting the tape pasted on the flange of the upper cover of the cigarette box, and then each mechanism returns to the initial position, and the second conveying unit 2-1 conveys the cigarette box to the lower cover opening device.

[0119] like Figure 23-25 As shown, the structure of the lower cover opening device 3 is similar to that of the upper cover opening device, including a third conveying unit 3-1, which is used to receive the cigarette box conveyed by the second conveying unit 2-1. Sliding bases 3-2 are provided on both sides of the third conveying unit 3-1, and the sliding bases 3-2 are connected to the fifth bidirectional driving mechanism. The structure of the fifth bidirectional driving mechanism is the same as that of the second bidirectional driving mechanism, and will not be repeated here. The fifth bidirectional driving mechanism can drive the two sliding bases to move toward or away from each other synchronously along the second direction.

[0120] The structure of the fifth bidirectional driving mechanism is the same as that of the second bidirectional driving mechanism, including a fifth cylinder 3 - 3 and a synchronous belt mechanism, which will not be described in detail here.

[0121] The fifth bidirectional driving mechanism is not connected to the lifting cylinder. A second cigarette sorting plate 3-4 is installed on the sliding base 3-2. The second cigarette sorting plate 3-4 is used to contact the upper cover. Two second suction cups 3-5 are provided under the second cigarette sorting plate 3-4. The second suction cups 3-5 are connected to the sliding base through the second suction cup cylinder 3-6. The second suction cups 3-5 are connected to the vacuum generator 3-9 installed on the sliding base 3-2.

[0122] Two second cutters 3-7 are also provided on the inner side of the second cigarette sorting plate 3-4. The two second cutters 3-7 are connected to the cutter seat through the cutter lifting cylinder 3-8. The two cutter seats are connected to the fourth bidirectional drive mechanism installed on the sliding base 3-2. The fourth bidirectional drive mechanism can drive the two cutter seats to move toward or away from each other synchronously along the first direction. The structure of the fourth bidirectional drive mechanism is the same as that of the third bidirectional drive mechanism, and will not be repeated here.

[0123] The second suction cup 3-5, the second suction cup cylinder 3-6, the second cutter 3-7, and the cutter lifting cylinder 3-8 together constitute the lower cover opening mechanism.

[0124] In this embodiment, no box pressing mechanism and box pressing plate are provided above the third conveying unit.

[0125] The working principle of the lower cover opening device is:

[0126] The third conveying unit 3-1 conveys the cigarette box. After it is in place, the two sliding bases 3-2 move toward each other and the cigarette box is centered by the second cigarette sorting plate 3-4. After the centering is completed, the two second cigarette sorting plates 3-4 press the upper cover, the second suction cup cylinder 3-6 extends, the second suction cup 3-5 absorbs the lower cover, and then the second suction cup cylinder 3-6 retracts to suck a gap in the lower cover. After the two second cutters 3-7 descend, they move away from each other in the first direction to cut the tape stuck on the flange of the cigarette box upper cover. Then all the mechanisms return to their initial positions, and the third conveying unit conveys the cigarette box to the upper and lower cover flipping device.

[0127] The fourth conveying unit 4-1 of the flip cover device 4 is used to receive the cigarette box conveyed by the third conveying unit. Figure 31 As shown, the fourth conveying unit adopts a powered roller conveyor line or a belt transmission mechanism. In this embodiment, the fourth conveying unit adopts a powered roller conveyor line.

[0128] The fourth conveying unit is also provided with a blocking mechanism 4-2 and a photoelectric detection element. The blocking mechanism 4-2 and the photoelectric detection element are arranged in the same manner as the blocking mechanism and the photoelectric detection element of the third conveying unit 3-1, and are not described again here.

[0129] like Figures 26-30 As shown, a flip plate 4-3 is provided on one side of the fourth conveying unit 4-2, and a push plate 4-6 is provided on the other side. The flip plate 4-3 and the push plate are arranged opposite to each other, the flip plate 4-3 is connected to the first telescopic member, and the push plate is connected to the second telescopic member. The first telescopic member and the second telescopic member can drive the flip plate and the push plate to move toward or away from each other synchronously. In this embodiment, the first telescopic member adopts a flip plate cylinder 4-4 whose axis is arranged along the second direction, and the second telescopic member adopts a push plate cylinder 4-7 whose axis is arranged along the second direction. The flip plate 4-3 and the push plate can move toward each other and contact the two sides of the cigarette box, thereby centering the cigarette box.

[0130] The flip cover plate cylinder 4-4 is fixed to a cylinder base, which is connected to a lifting member. The lifting member can drive the flip cover plate 4-3 to move up and down through the cylinder base. In this embodiment, the lifting member is a lifting cylinder 4-5 fixed to the frame of the flip cover device. The cylinder body of the lifting cylinder 4-5 is connected to the frame of the flip cover device, and its piston rod is connected to the cylinder base, which can drive the flip cover plate 4-3 to move up and down.

[0131] A first pressing plate is further provided above the fourth conveying unit 4 - 1 , and the first pressing plate is connected to a first pressing mechanism. The first pressing mechanism can drive the first pressing plate to contact the top surface of the cigarette box, thereby pressing the cigarette box.

[0132] In this embodiment, the first pressing mechanism adopts a first pressing cylinder, the cylinder body of the first pressing cylinder is fixed on the frame of the upper and lower cover flipping device, and the piston rod thereof is connected to the first pressing plate.

[0133] The working principle of the flip cover device is:

[0134] The fourth conveying unit 4 - 1 conveys the cigarette box. When the photoelectric detection element detects the cigarette box, the blocking plate of the blocking mechanism rises and the fourth conveying unit stops working.

[0135] The flip plate 4-3 is lowered to correspond to the push plate, and the flip plate 4-3 and the push plate move toward each other to center the cigarette box.

[0136] Then the first lower pressing plate moves downward, and the first lower pressing plate presses the cigarette box.

[0137] The flip plate rises to open the upper cover, and the flip plate 4-3 falls to open the lower cover. In this embodiment, in order to avoid damaging the cigarette box, the flip plate does not move straight up and down when moving up and down. Instead, during the up and down movement, when it approaches the flange of the box cover, the flip plate cylinder has a backward movement, and then extends forward after retreating, so as to avoid tearing the box cover of the cigarette box straight up and down.

[0138] After the upper and lower covers are flipped, the various components of the upper and lower cover flipping device return to their original positions.

[0139] like Figure 31-Figure 35 As shown, the cigarette pushing device 5 includes a fifth conveying unit 5-1, which is used to receive the cigarette box conveyed by the fourth conveying unit 4-1. The fifth conveying unit 5-1 adopts a belt transmission mechanism or a powered roller conveyor line. In this embodiment, the fifth conveying unit 5-1 adopts a powered roller conveyor line.

[0140] The fifth conveying unit 5 - 1 is also provided with a blocking mechanism and a photoelectric detection element. The setting method of the blocking mechanism and the photoelectric detection element is the same as that of the blocking mechanism and the photoelectric detection element on the fourth conveying unit, and will not be repeated here.

[0141] like Figure 36-Figure 37 As shown, a clamping mechanism is provided above the fifth conveying unit 5-1, and the clamping mechanism is connected to the lifting mechanism. The clamping mechanism includes a fifth bidirectional drive mechanism connected to the lifting mechanism, and two clamping plates are connected through the fifth bidirectional drive mechanism so that the two clamping plates move toward or away from each other in a direction parallel to the conveying direction of the fifth conveying unit.

[0142] In this embodiment, the lifting assembly adopts a lifting cylinder 5-2, the cylinder body of the lifting cylinder 5-2 is connected to the frame of the smoke pushing device, the piston rod of the lifting cylinder 5-2 is connected to the lifting plate, and the lifting plate is installed with a sixth bidirectional drive mechanism. In this embodiment, the sixth bidirectional drive mechanism adopts the existing double-headed cylinder 5-3, and the axis of the double-headed cylinder 5-3 is set along the conveying direction of the fifth conveying unit 5-1, and can output synchronous movement toward or away from each other. The piston rods on both sides of the double-headed cylinder 5-3 are respectively connected to the clamping plates 5-4. Through the double-headed cylinder 5-3, the two clamping plates 5-4 can make synchronous movement toward or away from each other.

[0143] A cigarette pushing mechanism is provided on one side of the fifth conveying unit 5-1. The cigarette pushing mechanism can adopt existing technology, including a telescopic mechanism 5-5 located on one side of the fifth conveying unit 5-1. The telescopic mechanism 5-5 is connected to the cigarette pushing component 5-6. The telescopic mechanism and the cigarette pushing component can adopt existing technology and will not be described in detail here.

[0144] The two clamping plates 5 - 4 can be used to center the cigarette box, thereby making the position of the cigarette box correspond to the position of the cigarette pushing mechanism, so that the cigarette pushing component can extend into the cigarette box.

[0145] A second pressing plate 5-7 is provided between the two clamping plates, and the second pressing plate is connected to the second pressing mechanism. The second pressing mechanism adopts a second pressing cylinder 5-8, and the second pressing cylinder 5-8 is fixed to the frame of the cigarette pushing device. The second pressing cylinder can drive the second pressing plate to press the cigarette box.

[0146] The end of the clamping plate close to the telescopic mechanism is provided with a middle cover flip mechanism, which includes a rotating drive member fixed to the clamping plate, the rotating drive member is connected to the suction cup seat, and the suction cup seat is provided with a third suction cup for adsorbing the middle cover.

[0147] In this embodiment, the rotating drive member adopts a rotating cylinder 5-9, the cylinder body of the rotating cylinder 5-9 is fixed to the clamping plate 5-4, and its conveying shaft is connected to the suction cup seat 5-10. The third suction cup 5-11 is installed on the suction cup seat 5-10, and the third suction cup 5-11 is used to be adsorbed and fixed to the middle cover of the cigarette box.

[0148] The working principle of the smoke pushing device is:

[0149] The fifth conveying unit conveys the cigarette box. When the photoelectric detection element detects the cigarette box, the blocking plate of the blocking mechanism rises and the fifth conveying unit stops working.

[0150] The clamping mechanism descends, and the two clamping plates move toward each other to center the smoke box.

[0151] After centering, the second pressing mechanism works, driving the second pressing plate to press the smoke box.

[0152] The rotary cylinder works to absorb the middle cover by the third suction cup, and then the rotary cylinder works again to open the middle cover by the third suction cup.

[0153] The telescopic mechanism works and pushes the cigarettes inside the cigarette box out through the cigarette pushing components to enter the next process.

[0154] After the cigarette pushing is completed, the various components of the cigarette pushing device return to their original positions.

[0155] The piece cigarette unpacking system of this embodiment can center the cigarette box in each process, meeting the smooth transmission and positioning requirements of the cigarette box in each process, thereby realizing the unpacking requirements of cigarette boxes of different specifications with one set of unpacking systems, improving the applicability of the entire piece cigarette unpacking system, and reducing the equipment cost and space occupied by the piece cigarette unpacking process.

Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
