Description

Technical Field

[0001] This invention relates to the technical field of tobacco processing stem manufacturing equipment, specifically to an automatic box-turning and feeding device for bagged cardboard packaging of tobacco stems. Background Technology

[0002] In tobacco processing stem manufacturing production lines, the process of manually cutting plastic bags to feed the bagged cardboard-packaged tobacco stems is generally carried out. Some companies, even with the use of mechanical equipment, still cannot avoid cutting the plastic bags before feeding the tobacco stems. This method of feeding by cutting plastic bags can cause a type of foreign matter to enter the tobacco stems, resulting in quality accidents.

[0003] Currently, tobacco stem manufacturers generally use a pre-compression method to bundle tobacco stem boxes. Sometimes, the inner plastic bag is squeezed into the gaps in the box lid and is difficult to remove. Furthermore, some manufacturers have paper pads at the bottom of the tobacco stem packaging boxes that are larger than the opening of the box. After feeding, the paper pads cannot be removed from the tobacco stem box, which will cause a series of problems such as difficulty in recycling the boxes and related equipment failures.

[0004] Although the Chinese patent CN116081043A document can realize the feeding of tobacco stems, there are still problems such as the paper pads inside the tobacco stem box not falling out after feeding is completed, which often causes the subsequent cardboard box folding, stacking and recycling equipment to malfunction; plastic bags are also stuck between the box lids and cannot be removed, causing the subsequent cardboard box folding, stacking and recycling equipment to malfunction. It requires constant manual monitoring and handling, resulting in low equipment reliability and a poor user experience.

[0005] Therefore, the key to solving the above-mentioned technical problems lies in developing a practical automatic box-turning and feeding device for bagged cardboard packaging of tobacco stems. Summary of the Invention

[0018] The beneficial effects of this invention are:

[0019] 1. This invention can replace manual labor to meet the process requirements of tobacco processing enterprises for automatic feeding of tobacco stems for bagged cardboard packaging in the stem manufacturing production line;

[0020] 2. This invention uses a box-turning and unloading method for feeding tobacco stems, which effectively avoids the impact of impurities generated by cutting plastic bags on the quality of tobacco stems.

[0021] 3. This invention uses a rotating clamping and lifting mechanism combined with a film-grabbing mechanism to grab and send out stuck plastic bags for recycling, which effectively solves the problem of difficult recycling of plastic bags due to sticking and eliminates the problem of subsequent carton folding, palletizing and recycling equipment failure caused by the inability to recycle plastic bags;

[0023] 5. The box-carrying mechanism used in this invention can effectively solve the problem of tobacco stems falling out during the process of picking up and lifting the tobacco stem box due to the movement of tobacco stems and the opening of the bottom cover of the box;

[0024] 6. The damping mechanism used in this invention can prevent the tobacco stems wrapped in plastic bags from slipping out of the cardboard box during the process of the tobacco stems falling over, thus preventing the tobacco stems from being difficult to separate from the plastic bags;

[0025] 7. The nailing mechanism used in this invention effectively solves the problem of tobacco stems being difficult to separate from plastic bags during the feeding process;

[0026] 8. During the process of turning over and feeding the boxes, this invention uses a box-carrying mechanism to tap the bottom of the box and a box-tapping mechanism to tap the sides of the box, which solves the problem of not being able to empty the plastic bags completely due to the folds that trap tobacco stems.

[0027] 9. After the tobacco stems are turned over and fed into the box, the left and right clamping arms need to be loosened a certain distance in order for the paper pad to fall smoothly. The limiting mechanism can effectively prevent the carton from slipping and deflecting during the loosening of the clamping arms, which may cause subsequent carton folding and stacking equipment malfunctions.

[0028] 10. After the tobacco stems are turned over and fed, the left and right clamping arms need to be loosened a certain distance in order for the paper pad to fall smoothly. During the loosening process, the precise position of the clamping arms opening and closing can be detected in real time to control the tightness of the clamping arms when the paper pad is released, thereby improving the reliability of the paper pad release.

[0060] like Figure 1 , Figure 13 and Figure 14As shown, the automatic box-turning and feeding device for bagged cardboard packaging of tobacco stems of the present invention includes: a tobacco stem separation device 1, a rotating clamp 2, a column 3, a clamping drive device 4, a support rod 5, a top rod mechanism 7, a film gripping mechanism 11, and a lifting device. A column 3 is mounted on one side of the tobacco stem separation device 1. Two linear guide rails 301 are mounted on the column 3 facing the tobacco stem separation device 1. The clamping drive device 4 is mounted on the two linear guide rails 301. The lifting device is mounted at the bottom end of the column 3. One end is fixed to the clamping drive device 4, allowing the clamping drive device 4 to move up and down along the column 3. The rotating clamp 2 is mounted on the clamping drive device 4 and is located above the tobacco stem discharge separation device 1. A support rod 5 is fixed on the column 3 at the upper end of the two linear guide rails 301, extending upwards and parallel to the tobacco stem discharge separation device 1. Two mounting seats 6 are mounted on the upper end of the support rod 5. The push rod mechanism 7 is fixed on the two mounting seats 6. The push rod mechanism 7 and The column 2 extends parallel to and towards the rotating clamp 2. The push rod mechanism includes: a swing rod 701, a locking nut 702, a rotating shaft 703, a sleeve 704, a crossbar 705, a connecting flange 706, and a rotary actuator 707. Two rotary actuators 707 are respectively fixed on two mounting seats 6. At least one crossbar 705 is welded between two parallel sleeves 704. Two connecting flanges 706 are respectively welded to the upper ends of two sleeves 704. The two connecting flanges 706 are fixed to the support by screws. At the lower end of rod 5, two rotating shafts 703 pass through two sleeves 704 respectively. The upper end of the rotating shaft 703 is connected to the rotary drive 707, and the lower end of the rotating shaft 703 extends out of the sleeve 704. One end of the swing rod 701 is fixed to the lower end of the rotating shaft 703 by two locking nuts 702. The rotary drive 707 rotates, driving the swing rod 701 to rotate. On the other side of the tobacco stem separation device 1, a film grabbing mechanism 11 is installed. The film grabbing mechanism 11 grabs away the plastic bags that fall on the tobacco stem separation device 1.

[0061] After the tobacco stems 8 are fed in, the tobacco stem box 10 is rotated and lifted. During the lifting process, the push rod mechanism 7, located directly above the tobacco stem box 10, pushes in through the gap in the long cover at the bottom of the tobacco stem box. As the tobacco stem box 10 is lifted to a higher position, the large-sized paper pad 12 is gradually pushed out of the cardboard box opening by the swing rod 701 and falls onto the material separation device 1 for vibration and recycling. Simultaneously, as the tobacco stem box 10 is gradually lifted, the rotary driver 707 drives the rotating shaft 703 to rotate. The rotating shaft 703 drives the swing rod 701 to rotate and swing. As the swing rod 703 swings and the tobacco stem box 10 gradually rises, the large-sized paper pad 12 cannot be flipped or deformed inside the cardboard box and is eventually swept downwards and pushed out of the cardboard box opening for recycling. A top view of the push rod mechanism 7 in its working state is shown below. Figure 14 As shown.

[0062] like Figure 8As shown, the film-gripping mechanism 11 includes: a guide rod 1102, a finger actuator 1103, a finger 1104, a mounting plate 1105, and a sixth actuator 1106. The bracket 1101 is fixed on the other side of the tobacco stem discharge separation device 1 opposite to the column 3. There is a fixing plate on the bracket 1101. The sixth actuator 1106 is fixed on the fixing plate on both sides of the sixth actuator 1106. The guide rod 1102 is respectively mounted on the fixing plate on both sides of the sixth actuator 1106. The mounting plate 1105 is fixed on the end of the sixth actuator 1106 and the two guide rods 1102. The finger actuator 1103 is fixed on the mounting plate 1105. The finger 1104 is mounted on the front end of the finger actuator 1103. The actuator 1106 drives the finger actuator 1103 and the finger 1104 to extend and retract. The finger actuator 1103 drives the finger 1104 to open and close. The finger actuator 1103 can be a pneumatic actuator to grip the plastic bag. During the packing and packaging of tobacco stems, plastic bags 9 are sometimes squeezed into the gaps at the bottom of the carton lid. After the cartons are turned over and the material is fed, the plastic bags 9 become stuck and cannot fall out. A film-gripping mechanism 11 is used to hold the plastic bags 9, and during the rotation, gripping, and lifting process, the plastic bags 9 are pulled and dropped into the vibrating conveyor recycling device 1. The film-gripping state is as follows: Figure 10 As shown.

[0063] like Figure 3 As shown, the limiting mechanism 204 includes: a first driver 2041, a limiting plate 2042, and a base 2043. The bottom surface of the base 2043 is fixed with the upper parts of the left clamping arm 203 and the right clamping arm 206. The first driver 2041 is fixed to the upper end of the base 2043. The limiting plate 2042 is movably installed at the front end of the first driver 2041. The limiting plate 2042 is located at the upper end of the tobacco stem box 10. The first driver 2041 drives the limiting plate 2042 to extend into the tobacco stem box 10. After the tobacco stem box 10 is filled, the cardboard box will shrink and deform during the clamping process, and the paper pad 12 will get stuck and difficult to fall. In order for the paper pad 12 to fall smoothly, the left clamping arm 203 and the right clamping arm 206 need to be relaxed a certain distance. The limiting mechanism 204 can effectively prevent the tobacco stem box 10 from slipping and deflecting during the relaxation of the left clamping arm 203 and the right clamping arm 206, which would cause difficulties in subsequent recycling. Figure 12 The diagram shows the working state of the limit mechanism 204.

[0064] like Figure 9As shown, the clamping drive device 4 includes: a rotating seat 401, a limiting block 402, a slewing bearing 403, a lifting seat 404, and a rotary driver 405. The bottom end of the lifting seat 404 is fixed to one end of the lifting device. The lifting seat 404 is mounted on two linear guide rails 301. The slewing bearing 403 is mounted on the lifting seat 404, and its outer ring is fixed to the lifting seat 404. The rotary driver 405 extends from one end of the slewing bearing 403 into the inner ring of the slewing bearing 403 and is fixed to the inner ring of the slewing bearing 403. The rotating seat 401 is fixed to the inner ring of the slewing bearing 403. The rotating clamp 2 is fixed on the rotating seat 401. The rotation of the rotary driver 405 drives the rotating seat 401 and the rotating clamp 2 to rotate. The two limiting blocks 402 are respectively mounted on the upper and lower ends of the lifting seat 404, and the angle between the line connecting them and the horizontal plane is 40° to 50°. The clamping drive device 4 serves as the power source for the rotating clamp, controlling the rotating clamp 2 to flip and pour materials at any angle, making the box-turning and feeding action more reliable. The limit block 402 works in conjunction with the clamping limit rod 212, providing mechanical limit protection and increasing the safety of the box-turning and feeding action.

[0065] like Figure 15 As shown, the left clamping arm 203 and the right clamping arm 206 include: a side wall 2031, an end plate 2032 and a slider 2033. The side wall 2031 is fixed to one side of the end plate 2032, and the slider 2033 is fixed to the other side of the end plate 2032. The slider 2033 is mounted on the linear guide rail 211. The nailing mechanism 207, the damping mechanism 205, the box mechanism 208, the detection switch 210 and the limit mechanism 204 are all mounted on the side wall 2031.

[0066] like Figure 2As shown, the rotating clamp 2 includes: a mounting frame 201, a drive device 202, a left clamping arm 203, a limiting mechanism 204, a damping mechanism 205, a right clamping arm 206, a nailing mechanism 207, a box-supporting mechanism 208, a box-tapping mechanism 209, a detection switch 210, a linear guide rail 211, and a limiting rod 212. One side of the mounting frame 201 is fixed to the rotating base 401 and equipped with a limiting rod 212, which cooperates with the two limiting blocks 402 mentioned above. The other side has a linear guide rail 211. The left clamping arm 203 and the right clamping arm 206 are movably mounted on the linear guide rail 211. The two ends of the drive device 202 are respectively fixed to the left clamping arm 203 and the right clamping arm 206, controlling the opening and closing of the left clamping arm 203 and the right clamping arm 206. Two sets of box-supporting mechanisms 208 are symmetrically mounted on the outer surfaces of the left clamping arm 203 and the right clamping arm 206. 208 rotatably supports the bottom of the tobacco stem box 10 from the lower ends of the left clamping arm 203 and the right clamping arm 206. A set of box-tapping mechanisms 209 are respectively installed on the middle portion of the outer side of the left clamping arm 203 and the right clamping arm 206. Two sets of nailing mechanisms 207 are symmetrically installed near the bottom ends of the left clamping arm 203 and the right clamping arm 206. The nails of the nailing mechanisms 207 pass through the left clamping arm 203 and the right clamping arm 206 and are inserted into the plastic bag of the tobacco stem box 10. 9. A set of detection switches 210 and two sets of symmetrical limit mechanisms 204 are respectively installed at the upper ends of the left clamping arm 203 and the right clamping arm 206. A capping mechanism 213 is installed at the front end of the left clamping arm 203 and the right clamping arm 206 respectively. The capping mechanism 213 hugs the tobacco stem box 10 inward. A damping mechanism 205 is also provided at the upper part of the right clamping arm 206. The damping mechanism 205 extends into the tobacco stem box 10 to slow down the falling speed of the tobacco stem.

[0067] like Figure 4As shown, the damping mechanism 205 includes: a U-shaped rod 2051, a first connecting rod 2052, a first lug 2053, a first crank 2054, a second actuator 2055, a moving stop lever 2056, and a connecting seat 2057. The bottom ends of the three first lugs 2053 are fixed to the upper part of the right clamping arm 206. One end of each of the two first connecting rods 2052 is hinged to one of the two end first lugs 2053, and the other end is fixed to the U-shaped rod 2051. A connecting seat 2057 is fixed on the corresponding U-shaped rod 2051 between the two end first lugs 2053. One end of the first crank 2054 is connected to the middle first lug 2055. 053 is hinged, and the other end is hinged to the connecting seat 2057. The middle part of the first crank 2054 is hinged to the end of the second driver 2055. The second driver 2055 is hingedly installed in the middle of the outer side of the right clamping arm 206. The U-shaped rod 2051 is arranged along one side of the tobacco stem box 10 and is located parallel above the tobacco stem box 10. The two ends of the movable stop lever 2056 are movably connected to the two ends of the U-shaped rod 2051. The second driver 2055 drives the first crank 2054 to extend or shorten, so that the first connecting rod 2052 rotates around the first ear seat 2053 into the tobacco stem box 10 to slow down the falling speed of the tobacco stem. The damping mechanism 205 is mounted on the right clamping arm 206 on the tipping side of the tobacco stem box 10. Before the tobacco stem box 10 begins to tip, the U-shaped rod 2051 of the damping mechanism 205 flips to directly above the edge of the cardboard box opening. During the tipping process, as the tobacco stem box 10 gradually tilts, the tobacco stems 8 flow and squeeze the opening of the plastic bag 9, filling the buffer area formed by the cardboard box and the U-shaped rod 2051. Then, the plastic bag 9 crosses the U-shaped rod 2051 and begins to be fed until feeding is complete. The damping mechanism 205, in conjunction with the tying mechanism 207, increases the resistance to the sliding of the plastic bag 9, effectively preventing the plastic bag 9 from wrapping too many tobacco stems 8 and falling off the tying to the material separation device 1, thus preventing the tobacco stems 8 from being effectively separated from the plastic bag 9.

[0068] like Figure 5 and Figure 10 As shown, the tacking mechanism 207 includes: a third driver 2071, a connecting seat 2072, a tacking nail 2073, and a guide block 2074. The bottom of the connecting seat 2072 is fixed near the bottom of the left clamping arm 203 and the right clamping arm 206. The third driver 2071 is fixed to the connecting seat 2072. One end of the tacking nail 2073 passes through the guide block 2074, and the other end is connected to the front end of the driver 2071. The third driver 2071 drives the tacking nail 2073 to pass through the tobacco stem box 10 and tack the plastic bag 9. During the clamping process, the tacking mechanism 207 works, and the tacking nail 2073 pierces into both sides of the tobacco stem box 10, passes through the plastic bag 9, and fixes the plastic bag 9. During the tipping and feeding process, the tacking nail 2073 hangs on the plastic bag 9 until the feeding is completed. The tacking nail 2073 retracts and releases the plastic bag 9 onto the material separation device 1 for vibration conveying and recycling.

[0069] like Figure 6As shown, the pallet mechanism 208 includes: a fourth drive 2081, a second crank 2082, a second connecting rod 2083, a bracket 2084, a roller 2085, and a mounting base 2086. The base plate of the mounting base 2086 is fixed to the left clamping arm 203 and the right clamping arm 206. The upper end of the second crank 2082 is hinged to the front end of the fourth drive 2081, the lower end of the second crank 2082 is hinged to one end of the second connecting rod 2083, and the middle of the second crank 2082 is hinged to the middle of the mounting base 2086. The upper end of the bracket 2084 is hinged to the bottom end of the mounting base 2086, and the middle of the bracket 2084 is hinged to the other end of the connecting rod 2083. A roller 2085 is installed at the front bottom of the bracket 2084. The fourth drive 2081 drives the second crank 2082 to swing, the second crank 2082 drives the second connecting rod 2083 to swing and enter the dead position, and the second connecting rod 2083 drives the bracket 2084 to swing around the mounting base 2086, so that the bracket 2084 inserts into the bottom of the tobacco stem box 10 to support the tobacco stem box 10. During the clamping process, because the tobacco stem box 10 is a nested inner and outer cardboard box, and the cardboard box filled with tobacco stems 8 deforms greatly, the clamping force may not be able to completely overcome the weight of the tobacco stem box 10 itself. The inner box may fall out of the outer box, and during the rotation, clamping and lifting process, the tobacco stems 8 may flow and open the bottom cover of the cardboard box and fall out. Therefore, the box support mechanism 208 can effectively solve the above problems. On the other hand, after the box is turned over and the material is fed, the box-carrying mechanism 208 can tap the bottom of the carton to vibrate and shake out the tobacco stems 8 from the folds of the plastic bag 9, thus solving the problem of the tobacco stems 8 not being completely emptied. In addition, the rollers 2085 installed on the bracket 2084 squeeze and rotate the carton lid during the rotating clamping and lowering process, which can prevent the lid from being torn.

[0070] like Figure 7 As shown, the box-tapping mechanism 209 includes: an upper fixed seat 2091, a second ear seat 2092, a fifth driver 2093, a third connecting rod 2094, a striking plate 2095, and a middle fixed seat 2096. The upper fixed seat 2091 is fixed on the upper side of the left clamping arm 203 and the right clamping arm 206. One end of the fifth driver 2093 is hinged to the upper fixed seat 2091 through the second ear seat 2092, and the other end is hinged to one end of the third connecting rod 2094. The middle part of the third connecting rod 2094 is hinged to the middle fixed seat 2096 fixed on the side of the left clamping arm 203 and the right clamping arm 206. The other end of the third connecting rod 2094 is fixedly connected to the striking plate 2095. The fifth driver 2093 drives the third connecting rod 2094 to swing, so that the striking plate 2095 taps the side wall of the tobacco box 10. The box-tapping mechanism 209 is used to tap the side of the carton during the box-turning and feeding process, increasing the vibration amplitude of the carton and causing the tobacco stems 8 from the folds of the plastic bag 9 to fall out, thus helping to solve the problem of incomplete emptying of tobacco stems. The automatic box-turning and feeding device for bagged carton packaging of tobacco stems of the present invention includes the following working process:

[0071] Initialization: The left clamping arm 203 and right clamping arm 206 of the rotating clamp 2 move outward and open simultaneously. The bracket 2084 of the box-carrying mechanism 208 is in the open state, the rivet 2073 of the rivet mechanism 207 is in the retracted state, the U-shaped rod 2051 of the damping mechanism 205 is in the low position, the striking plate 2095 of the box-tapping mechanism 209 is in the open state, and the limiting plate 2042 of the limiting mechanism 204 is in the retracted state.

[0072] Clamping: Tobacco stems 8, wrapped in plastic bags 9 and placed in tobacco stem boxes 11, are conveyed to the clamping station. The carton lid and plastic bag 9 are fully opened by the upstream equipment. The initialized rotating clamp 2 rotates via the column 3 and descends to the clamping position of the tobacco stem box 11. During the descent of the rotating clamp 2, the four sides of the carton lid are pressed downward by the mounting bracket 201, the lid pressing mechanism 213 (which acts as a guide rod), and the rollers 2085 of the box-supporting mechanism 208. The left clamping arm 203 and the right clamping arm 206 simultaneously retract inward, pressing the lid tightly against the outer side of the tobacco stem box 11 and clamping it. After clamping, the detection switch 210 is triggered, the box-supporting mechanism 208 is activated, and the crank 2082 and connecting rod 2083 are straightened and aligned, entering the dead position. The bracket 2084 rotates to support the bottom of the tobacco stem box 10. The U-shaped rod 2051 of the damping mechanism 205 operates and rotates to directly above the opening of the tobacco stem box 10. The nailing mechanism 207's nailing 2073 action inserts into the tobacco stem box 10 and secures the plastic bag 9. The limiting mechanism 204's limiting plate 2042 is pushed out and presses against the edge of the opening of the tobacco stem box 10.

[0073] Feeding from the box: After being clamped, the tobacco stem box 10 is lifted and rotated by the column 3 to directly above the material separation device 1. The clamping drive device 4 drives the rotating clamp 2 to slowly rotate at a certain angle to feed the material. During the tilting and flipping process of the tobacco stem box 10, the plastic bag 9 is squeezed and flipped over by the flow of tobacco stems 8 and over the U-shaped bar 2051 of the damping mechanism 205. The tobacco stems 8 are poured out from the plastic bag 9 and fall into the material separation device 1. After being processed by vibrating screening, they are used in subsequent processes. After the tobacco stems 8 are fed, the box-tapping mechanism 209 taps the two sides of the tobacco stem box 10, and the box-supporting mechanism 208 taps the bottom of the tobacco stem box 10, vibrating and dropping the residual tobacco stems 8 accumulated in the folds of the plastic bag 9, thus solving the problem of unclean feeding of tobacco stems 8.

[0074] Plastic bag recycling: During the feeding process, the plastic bag 9 is suspended inside the tobacco stem box 10 under the combined action of the damping mechanism 205 and the tying mechanism 207. After feeding is completed, the tying nail 2073 of the tying mechanism 207 retracts, the U-shaped rod 2051 of the damping mechanism 205 returns to its original position, and the plastic bag 9 is released onto the material separation device 1 and vibrated out for recycling. However, sometimes when the tobacco stems 8 are packed and compressed, the plastic bags 9 may get squeezed into the gaps between the bottom lid of the tobacco stem box 10 and become difficult to fall off. At this time, the film gripping mechanism 11 works, the driver 1106 pushes out the finger driver 1103, the finger driver 1103 drives the fingers 1104 to open and close instantly, clamping the plastic bag 9 between the fingers 1104. Then the driver 1106 drives the finger driver 1103 to retract, and the rotating clamp 2 drives the tobacco stem box 10 to rise. The plastic bag 9 is pulled off and released onto the material separation device 1 for vibration and recycling, which effectively solves the problem of plastic bag 9 breaking and generating a type of debris and the difficulty of recycling.

[0075] Paper pad recycling: After the cigarette pack is turned over and fed, the paper pad 12 in some cigarette packs is smaller than the inner opening of the cigarette stem box 10. When the staples 2073 of the staples 207 retract and release the plastic bag 9, the paper pad 12 also falls onto the material separation device 1 and is vibrated and sent out for recycling. However, sometimes the paper pad 12 in some cigarette packs is larger than the inner opening of the cigarette stem box 10. When the staples 2073 of the staples 207 retract and release the plastic bag 9, the paper pad 12 is stuck and cannot fall. At this time, the cigarette stem box 10 after feeding is lifted by the rotating clamp 2. During the lifting process, the top rod 7 set directly above the cigarette stem box 10 pushes out from the gap of the long cover at the bottom of the cigarette stem box 10. As the cigarette stem box 10 is lifted to a high position, the large paper pad 12 is gradually pushed out of the box opening by the top rod 7 and falls onto the material separation device 1 for vibration and recycling. This effectively avoids the problem of difficulty in automatic folding and recycling of the cigarette stem box later.

[0076] Return to zero position: After the paper pad 12 is recycled, the rotating clamp 2 is rotated by the column 3 to hand over the empty tobacco stem box 10 to the carton recycling equipment. The column 3 rotates to the reset position, the clamping drive device 4 descends to the low position of the column 3, and the clamping drive device 4 drives the rotating clamp 2 to rotate back to a certain angle to reset. All the motion mechanisms of the rotating clamp 2 are reset, and the rotating clamp 2 is rotated by the column 3 to be directly above the incoming tobacco stem box 10 to wait for the next clamping operation.

[0077] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description.
