[0028] The following describes a folding device according to a first embodiment of the present invention and a handle production apparatus according to a second embodiment of the present invention, with reference to the accompanying drawings. It should be noted that, for ease of description and understanding, in the embodiments of the present invention, the front-to-back direction is referred to as the first direction, the left-to-right direction is referred to as the second direction, and the up-to-down direction is referred to as the third direction. The first direction is the direction in which the handle is conveyed, and the first, second, and third directions are mutually perpendicular.

[0029] The first embodiment of the present invention provides a folding device 100 for folding the connecting portion 210. Figures 1 to 3 As shown, the folding device 100 includes a body 110 and a folding mechanism 120. The body 110 is the main body of the folding device 100 and is used to support various mechanical components. The body 110 has a support surface 1111 along the vertical direction, which is used to place and transport the handle 200. The body 110 defines a receiving groove 113 on both sides of the body 110 along the front-to-back direction, namely the left and right sides.

[0030] The folding mechanism 120 includes a rotating member 121 and a pressing block assembly 122. The rotating member 121 is rotatably connected to the body 110 and is located in the receiving groove 113. The rotating member 121 has an abutment surface 1212 in the vertical direction. The abutment surface 1212 is arranged below the support surface 1111 in the vertical direction. That is, the height of the abutment surface 1212 is lower than the height of the support surface 1111 in the vertical direction. When the handle 200 is placed on the support surface 1111 and is not folded, the handle 200 does not contact the abutment surface 1212. The pressure block assembly 122 includes a first pressure block 1221 and a second pressure block 1222. The first pressure block 1221 and the second pressure block 1222 are driven by driving components such as a cylinder or a motor, so that they can move in the up and down directions and left and right directions relative to the body 110 and the rotating member 121. The first pressure block 1221 and the second pressure block 1222 are arranged above the body 110 and the rotating member 121 in the up and down directions. The first pressure block 1221 corresponds to the abutment surface 1212 in the up and down directions, and the second pressure block 1222 corresponds to the support surface 1111 in the up and down directions.

[0031] Specifically, see Figure 4 and Figure 5 As shown, handle 200 includes a handle 220 and a connecting portion 210. Connecting portions 210 are located at both ends of handle 220. Initially, both handle 220 and connecting portion 210 are strip-shaped. When handle 200 is used for lifting, connecting portion 210 needs to be folded to accommodate the container. Handle 200 includes a first adhesive surface 211, and connecting portion 210 includes a second adhesive surface 212, a third adhesive surface 213, a fourth adhesive surface 214, and a fifth adhesive surface 215, which are sequentially connected.

[0032] In one example, see Figures 1 to 5 As shown, when the connecting portion 210 is folded, the handle 200 is placed on the support surface 1111. At this time, the handpiece 220 is supported by the support surface 1111, and the connecting portion 210 extends beyond the support surface 1111 to correspond vertically with the abutment surface 1212. During folding, the first pressing block 1221 moves downward. Since both the first pressing block 1221 and the connecting portion 210 correspond to the abutment surface 1212, during the descent of the first pressing block 1221, the first pressing block 1221 applies pressure to the connecting portion 210, causing the connecting portion 210 to descend along with the first pressing block 1221, thereby allowing the connecting portion 210 to enter the receiving groove 113 and abut against the rotating member 121 located in the receiving groove 113. At this time, due to the height difference between the abutting surface 1212 and the supporting surface 1111, the first pressing block 1221 acts to cause a bend between the connecting portion 210 and the handle 200, i.e., the second adhesive surface 212 bends downward relative to the first adhesive surface 211. In this embodiment, when the first pressing block 1221 moves downward, the first pressing block 1221 also moves toward the second pressing block 1222 to press the second adhesive surface 212, causing the second adhesive surface 212 to bend relative to the first adhesive surface 211 when attached to the side wall of the body 110, thereby improving the bending efficiency of the connecting portion 210.

[0033] The rotating member 121 then flips toward the body 110. When the contact surface 1212 contacts the side wall of the body 110, the second adhesive surface 212 and a portion of the third adhesive surface 213 are affixed. At this point, the fourth adhesive surface 214 and the fifth adhesive surface 215 are located above the support surface 1111. Finally, the second pressing block 1222 moves downward to press against the fourth adhesive surface 214 and the fifth adhesive surface 215, causing the fourth adhesive surface 214 to bend relative to the third adhesive surface 213. When the second pressing block 1222 descends to contact the support surface 1111, the fifth adhesive surface 215 is pressed by the second pressing block 1222 and bends relative to the fourth adhesive surface 214, thereby causing the fifth adhesive surface 215 to affix to the first adhesive surface 211. At the same time, when the second pressing block 1222 moves downward, the second pressing block 1222 will gradually move toward the first pressing block 1221 , so that the fourth adhesive surface 214 is attached to the third adhesive surface 213 , thereby achieving the folding of the connecting portion 210 .

[0034] In one example, when the rotating member 121 is flipped relative to the body 110 so that the second bonding surface 212 and the third bonding surface 213 are in contact, the rotating member 121 returns to its initial position. The first pressing block 1221 moves downward again to abut the third bonding surface 213. At this time, the connecting portion 210 is clamped between the first pressing block 1221 and the body 110. When the second pressing block 1222 presses the fourth bonding surface 214 to abut the third bonding surface 213, the second pressing block 1222 moves toward the second pressing block 1222 until the second pressing block 1222 abuts the first pressing block 1221. The third bonding surface 213 and the fourth bonding surface 214 are clamped together between the first pressing block 1221 and the second pressing block 1222 for contact. The first pressing block 1221 provides support for the contact between the two bonding surfaces, thereby improving the contact effect of the bonding surface of the connecting portion 210.

[0035] In the related art, when folding the connecting portion 210, it is often necessary to adjust the folding position of the connecting portion 210, which results in low folding efficiency of the connecting portion 210 and low production efficiency of the handle 200. Moreover, after adjusting the folding position, it is easy to cause the folding positions of each handle 200 to be inconsistent, thereby reducing the stability of the handle 200. Compared with the related art, the folding device 100 of the embodiment of the present application causes the first pressing block 1221, the second pressing block 1222 and the rotating member 121 to perform specified movable operations, and through the mutual cooperation between the three, the connecting portion 210 of each handle 200 is folded at the same position during the folding process, thereby reducing quality problems caused by folding position deviation of the connecting portion 210 and improving the stability and folding efficiency of the handle 200.

[0036] In some embodiments, see Figures 3 to 6As shown, the rotating member 121 also includes an abutting portion 1211 and a bent portion 1213. The abutting portion 1211 is rotatably connected to the body 110, and the abutting surface 1212 is provided on the abutting portion 1211. The bent portion 1213 is connected to the abutting portion 1211 and extends upward relative to the abutting portion 1211. The direction in which the abutting surface 1212 is provided is the same as the direction in which the bent portion 1213 extends. Specifically, when the abutting portion 1211 is flipped relative to the body 110, the connecting portion 210 of the handle 200 rotates along with the abutting portion 1211, and the third adhesive surface 213 and the second adhesive surface 212 are abutted against each other and clamped by the abutting portion 1211 and the side wall of the body 110. Since the bent portion 1213 extends upward, an angle is formed between the bent portion 1213 and the abutting portion 1211. The length of the connecting portion 210 in the left-right direction is greater than the length of the rotating member 121 in the left-right direction, that is, the connecting portion 210 partially extends beyond the rotating member 121. When the abutting surface 1212 contacts the side wall of the body 110, the connecting portion 210 bends under the action of the bending portion 1213, thereby bending the fourth adhesive surface 214 relative to the third adhesive surface 213, so that the fourth adhesive surface 214 and the fifth adhesive surface 215 are located above the support surface 1111 in the vertical direction. The bending portion improves the bending efficiency of the connecting portion 210 and enables the second pressing block 1222 to better contact the fourth adhesive surface 214 and the fifth adhesive surface 215, thereby improving the folding efficiency of the connecting portion 210.

[0037] In some embodiments, see Figures 1 to 6As shown, the body 110 includes a guide member 112 and a main body 111. The guide member 112 is provided on both sides of the main body 111 in the front-to-back direction, i.e., on the left and right sides. The guide member 112 and the main body 111 are spaced apart, and the two together define a receiving groove 113. The receiving groove 113 is located between the guide member 112 and the main body 111. The spacing between the main body 111 and the guide member 112 is the width of the receiving groove 113 in the left-right direction. The guide member 112 is recessed in the left-right direction toward one side of the rotating member 121 to form a guide groove 1121. The guide groove 1121 corresponds to the abutment surface 1212 in the left-right direction. Specifically, when the connecting portion 210 contacts the rotating member 121 under the pressure of the first pressing block 1221, due to the length of the connecting portion 210 and the pressure of the first pressing block 1221, the third bonding surface 213 and the second bonding surface 212 of the connecting portion 210 are bent, so that the third bonding surface 213 contacts the abutting surface 1212, and the fourth bonding surface 214 and the fifth bonding surface 215 extend out of the rotating member 121. The connecting portion 210 extending out of the rotating member 121 is then accommodated in the accommodating groove 113. The accommodating groove 113 can limit the position of the connecting portion 210 to ensure the corresponding relationship between the connecting portion 210 and the abutting surface 1212, thereby preventing the position of the connecting portion 210 in the front-to-back direction from being offset relative to the rotating member 121, which would affect the rotation of the rotating member 121 to bend the fourth bonding surface 214.

[0038] In some embodiments, see Figure 2 and Figure 3 As shown, the pressure block assembly 122 also includes a fixed plate 1223. The number of fixed plates 1223 is adapted to the number of pressure blocks. Since the functions and movement directions of the first pressure block 1221 and the second pressure block 1222 are not exactly the same when the first pressure block 1221 and the second pressure block 1222 move to fold the connecting portion 210, the first pressure block 1221 and the second pressure block 1222 are respectively provided with a fixed plate 1223. A first channel 1224 and a second channel 1225 are provided on the fixed plate 1223. The first channel 1224 and the second channel 1225 are connected. After the first pressure block 1221 and the second pressure block 1222 are connected to the fixed plate 1223, they will slide along the path of the first channel 1224 and the second channel 1225, thereby moving in the up and down directions and the left and right directions relative to the body 110 and the rotating member 121.

[0039] Specifically, when the first pressing block 1221 moves downward, it also needs to move toward the second pressing block 1222 so that the second adhesive surface 212 contacts the side wall of the body 110 and bends relative to the first adhesive surface 211. Furthermore, when the second pressing block 1222 moves downward, it also needs to move toward the first pressing block 1221 so that the fourth adhesive surface 214 adheres to the third adhesive surface 213. Therefore, an angle is formed between the first channel 1224 and the second channel 1225, allowing the second channel 1225 to be offset relative to the first channel 1224, i.e., offset to the left or to the right. This allows the first pressing block 1221 and the second pressing block 1222 to move along the second channel 1225, either downward or gradually in the left-right direction, thereby satisfying the requirement for the connection portion 210 to fold. Furthermore, by utilizing the offset of the second channel 1225 , the left-right movement of the first pressing block 1221 and the second pressing block 1222 is gradual, thereby improving the bending and fitting accuracy between the bonding surfaces, thereby improving the molding quality of the handle 200 .

[0040] In some embodiments, see Figures 7 to 9 As shown, the folding device 100 further includes a creasing mechanism 130, which is disposed upstream of the folding mechanism 120 in the front-to-back direction. The creasing mechanism 130 includes a first clamping block 131 and a second clamping block 132 disposed in an opposed vertical direction. The first clamping block 131 is connected to the body 110, and the second clamping block 132 is disposed above the first clamping block 131. The second clamping block 132 is movable in the vertical direction relative to the first clamping block 131, thereby enabling the first clamping block 131 and the second clamping block 132 to jointly clamp the connecting portion 210 of the handle 200 to form an indentation on the connecting portion 210. The indentation formed by the first clamping block 131 and the second clamping block 132 facilitates the bending of the connecting portion 210 when the connecting portion 210 is conveyed to the folding mechanism 120 for folding, thereby improving the bending efficiency of the connecting portion 210 and the production efficiency of the handle 200.

[0041] Further, see Figures 7 to 9As shown, a first pressing rib 1311 and a second pressing rib 1312 are provided along the vertical direction on the side of the first clamping block 131 facing the second clamping block 132. A first protrusion 1321 and a second protrusion 1324 are provided along the vertical direction on the side of the second clamping block 132 facing the first clamping block 131. The first protrusion 1321 and the second protrusion 1324 are provided along the horizontal direction between the first pressing rib 1311 and the second pressing rib 1312. The handle 200 has two opposing sides along the vertical direction. When the handle 200 is conveyed between the first clamping block 131 and the second clamping block 132, the two sides of the handle 200 contact the first clamping block 131 and the second clamping block 132, respectively. The first pressing rib 1311 and the second pressing rib 1312 form an indentation on the lower side of the handle 200, while the first protrusion 1321 and the second protrusion 1324 form an indentation on the upper side of the handle 200.

[0042] Specifically, see Figures 1 to 9 As shown, the handle 200 has a first indentation 231, a second indentation 232, a third indentation 233, a fourth indentation 234, a fifth indentation 235, and a sixth indentation 236. The first indentation 231 is formed by extrusion of the first indentation rib 1311, and the sixth indentation 236 is formed by extrusion of the second indentation rib 1312. The first indentation 231 and the sixth indentation 236 are located on different sides of the handle 200 from the other four indentations. For ease of description and illustration, the indentations are shown on the same side in the figures. The second indentation 232 and the third indentation 233 are formed by extrusion of the first raised portion 1321, and the fourth indentation 234 and the fifth indentation 235 are formed by extrusion of the second raised portion 1324.

[0043] In one embodiment, see Figures 1 to 9As shown, when the handle 200 is folded, the second adhesive surface 212 bends downward relative to the first adhesive surface 211 along the first indentation 231. The third adhesive surface 213 bends upward relative to the second adhesive surface 212 along the second indentation 232 and the third indentation 233, and is bonded to the second adhesive surface 212. The fourth adhesive surface 214 bends relative to the third adhesive surface 213 along the fourth indentation 234 and the fifth indentation 235, and is bonded to the third adhesive surface 213. Finally, the fifth adhesive surface 215 bends relative to the fourth adhesive surface 214 along the sixth indentation 236, and is bonded to the first adhesive surface 211. During the folding process of this embodiment, when the second adhesive surface 212 and the fifth adhesive surface 215 are bent, they are bent toward the outer side surface (lower side surface) of the connecting portion 210, and when the third adhesive surface 213 and the fourth adhesive surface 214 are bent, they are bent toward the inner side surface (upper side surface) of the connecting portion 210. Only in this way can the adhesive surfaces be bent to form a closed structure. Therefore, it is necessary to set the first indentation 231 and the sixth indentation 236 on different sides of the handle 200 from the other four indentations. The first indentation 231 and the sixth indentation 236 are located outside the closed structure, thereby improving the folding efficiency of the connecting portion 210, further promoting the unification of the folding position of the connecting portion 210, and ensuring the stability of the handle 200.

[0044] Further, see Figure 8 As shown, in some embodiments, the first protrusion 1321 and the second protrusion 1324 are spaced apart. The first protrusion 1321 includes a third pressure rib 1322 and a fourth pressure rib 1323 connected thereto, and the second protrusion 1324 includes a fifth pressure rib 1325 and a sixth pressure rib 1326 connected thereto. The third pressure rib 1322 and the fourth pressure rib 1323 are connected to the second clamping block 132 at one end and spaced apart at the other end. Specifically, the third pressure rib 1322 and the fourth pressure rib 1323 are spaced apart in the vertical direction, away from one end of the second clamping block 132. Similarly, the fifth pressure rib 1325 and the sixth pressure rib 1326 are connected to the second clamping block 132 at one end and spaced apart at the other end. Specifically, the fifth pressure rib 1325 and the sixth pressure rib 1326 are spaced apart in the vertical direction, away from one end of the second clamping block 132.

[0045] Specifically, when the handle 200 is folded, a gap forms between the adhesive surfaces. Therefore, a reinforcement member 240 is positioned in the gap formed between the adhesive surfaces to enhance the strength of the connecting portion 210. By spacing the third and fourth ribs 1322, 1323, and the fifth and sixth ribs 1325, 1326, away from the end of the second clamping block 132, adjacent indentations are formed on the connecting portion 210. Specifically, the second and third indentations 232, 233 are positioned adjacent to each other, and the fourth and fifth indentations 234, 235 are positioned adjacent to each other. When the connecting portion 210 is folded, the adjacent indentations separate the third adhesive surface 213 from the second and fourth adhesive surfaces 212, 214, respectively, thereby reserving space for the reinforcement member 240. Furthermore, the adjacent indentations increase the thickness of the reinforcement member 240, thereby enhancing the structural strength of the connecting portion 210 and preventing damage to the connecting portion 210 when lifting objects.

[0046] In some embodiments, see Figure 1 and Figure 9 As shown, the folding device 100 also includes a second feeding mechanism 140. Currently, the material of the handle 200 has gradually changed from plastic to paper. When the handle 200 is folded, gaps will form between the various bonding surfaces of the connecting portion 210 due to the folding of the connecting portion 210. Therefore, a reinforcement member 240 is often provided in the gaps formed between the bonding surfaces to enhance the strength of the connecting portion 210. The reinforcement member 240 is also made of paper and is provided in the gaps between the third bonding surface 213 and the second bonding surface 212 and the fourth bonding surface 214, respectively. One side of the reinforcement member 240 is in contact with the third bonding surface 213, and the other side is in contact with the second bonding surface 212 and the fourth bonding surface 214. The second feeding mechanism 140 is used to transport the reinforcement member 240. The second feeding mechanism 140 is provided upstream of the folding mechanism 120 in the front-to-back direction. When the handle 200 is conveyed to the second feeding mechanism 140, the reinforcement 240 will be placed on the connecting portion 210 to be conveyed together with the handle 200. When the connecting portion 210 is folded, the reinforcement 240 will be wrapped by the adhesive surface, thereby improving the strength of the connecting portion 210 and extending the service life of the connecting portion 210.

[0047] Specifically, in one of the examples, see Figure 9As shown, the second feeding mechanism 140 includes an adsorbent 141 and a moving member 142. The moving member 142 is a driving device (e.g., a motor or cylinder). The moving member 142 is connected to the adsorbent 141 to drive the adsorbent 141 relative to the body 110. When the handle 200 is conveyed to the second feeding mechanism 140, the adsorbent 141 adsorbs the reinforcement member 240 and, driven by the moving member 142, moves the reinforcement member 240 toward the handle 200. The reinforcement member 240 is then placed on the third adhesive surface 213, and the reinforcement member 240 is conveyed along with the handle 200 toward the folding mechanism 120. When the connecting portion 210 is folded, the second adhesive surface 212 first bends relative to the first adhesive surface 211 to begin the folding process, and the fifth adhesive surface 215 finally abuts against the first adhesive surface 211 to complete the folding process. The bonding surfaces together form a closed structure, and the reinforcing member 240 is located in the gaps between the third bonding surface 213 and the second bonding surface 212 and the fourth bonding surface 214 .

[0048] In some embodiments, see Figure 10 and Figure 11 As shown, the conveyor belt 150 is provided with a plurality of partitions 151. The partitions 151 are provided on a side of the conveyor belt 150 facing away from the support platform 510 and protrude upward. The plurality of partitions 151 are spaced apart in the front-to-back direction, thereby providing the conveyor belt 150 with a plurality of separately arranged receiving slots 152 for receiving the handles 200.

[0049] Specifically, the handle 200 is placed in the receiving groove 152 and sequentially undergoes the steps of folding, conveying, and pressure holding. By providing the partition 151, the safety and efficiency of the conveying of the handle 200 can be improved, the possibility of damage to the handle 200 can be reduced, and the subsequent sorting work can be simplified. At the same time, since the connecting portion 210 of the handle 200 enters the pressure holding cavity of the support plate 523 and the pressure holding plate 522, the connecting portion 210 will contact the support plate 523 or the pressure holding plate 522. Under the conveyance of the conveyor belt 150, the connecting portion 210 will be affected by friction, so that the conveying speed of the handle 200 is affected to a certain extent. By separating the handles 200 by the partition 151, it is possible to prevent the handles 200 from stacking or contacting and entangled with each other during the conveying process, thereby affecting the discharge and conveying of the handles 200.

[0050] In some embodiments, the partitions 151 may be detachable, and the user may adjust the distance between adjacent partitions 151 or replace the partitions 151 with different heights and shapes according to the size of the transported handles 200 to accommodate the transportation requirements of handles 200 of different sizes.

[0051] The second embodiment of the present invention provides a handle production device 10, see Figures 1 to 10 As shown, the handle production equipment 10 includes a first feeding mechanism 300, a gluing mechanism 400, and a folding device 100 described in any of the above embodiments. The first feeding mechanism 300 is used to convey the unfolded handle 200. The gluing mechanism 400 is disposed downstream of the first feeding mechanism 300. The gluing mechanism 400 is used to receive the handle 200 conveyed by the first feeding mechanism 300 and apply glue to the connecting portion 210 of the handle 200. The folding mechanism 120 is disposed downstream of the gluing mechanism 400 in the front-to-back direction. The folding mechanism 120 is used to fold the glued connecting portion 210 so that the adhesive surfaces of the connecting portion 210 can be bonded together.

[0052] The handle production apparatus 10 of this embodiment of the present invention utilizes a glue coating mechanism 400 to apply glue to the connecting portion 210, ensuring accurate control of the glue quantity and coating position. Furthermore, the synergistic action of the rotating member 121 and the pressing block assembly 122 ensures that each connecting portion 210 is folded uniformly each time, achieving a seamless connection and forming of the connecting portions 210. This improves the production quality and efficiency of the handle 200.

[0053] Further, in some embodiments, see Figures 1 to 11 As shown, the handle production equipment 10 also includes a pressure-holding mechanism 500 for clamping the connecting portion 210. The pressure-holding mechanism 500 includes a support platform 510 and a pressure-holding assembly 520. The support platform 510 is the main body of the pressure-holding mechanism 500. The pressure-holding assembly 520 includes a driving member 521, a pressure-holding plate 522, and a support plate 523. Since the two ends of the handle 200 are folded to form the connecting portion 210, and the support plates 523 are used to support the connecting portion 210 of the handle 200, in this embodiment, there are two support plates 523. The two support plates 523 are connected to the support platform 510 and are arranged on both sides of the conveyor belt 150 in the front-to-back direction, i.e., on the left and right sides of the conveyor belt 150. In other embodiments, the number of support plates 523 can also be one, three, or four, etc., as long as the support plates 523 can support the connecting portions 210 at both ends of the handle 200.

[0054] Furthermore, the pressure-maintaining plate 522 is arranged in the circumferential direction of the support plate 523 along the front-to-back direction, and the pressure-maintaining plate 522 and the support plate 523 are spaced apart, defining a pressure-maintaining spacing between the two. When the folded and formed handle 200 is conveyed to the pressure-maintaining mechanism 500, the connecting portion 210 of the handle 200 will be located within the pressure-maintaining spacing between the pressure-maintaining plate 522 and the support plate 523, thereby achieving a pressure-maintaining effect on the connecting portion 210. The driving member 521 is connected to the pressure-maintaining plate 522. The driving member 521 can drive the pressure-maintaining plate 522 to move relative to the support plate 523, changing the pressure-maintaining spacing between the pressure-maintaining plate 522 and the support plate 523, thereby changing the tightness of the pressure-maintaining plate 522 and the support plate 523 on the connecting portion 210. At the same time, the driving member 521 can also make the pressure-maintaining plate 522 and the support plate 523 adapt to connecting portions 210 of different thicknesses.

[0055] After the connecting portion 210 is folded and formed, the handle 200 will be driven by the conveyor belt 150 to be transported toward the pressure-keeping assembly 520. In this embodiment, there are multiple pressure-keeping plates 522. Since the bonding surface of the connecting portion 210 has a fitting portion in both the up-down and left-right directions, pressure-keeping plates 522 are provided on the upper side, left side, and right side of the support plate 523, and the pressure-keeping distance formed by the support plate 523 and the pressure-keeping plate 522 is adapted to the fitting portion of the connecting portion 210. During pressure holding, the fitting portion of the first bonding surface 211 and the fifth bonding surface 215 is placed in the pressure-keeping distance between the support plate 523 and the pressure-keeping plate 522 in the up-down direction, and the fitting portion of the second bonding surface 212, the third bonding surface 213, and the fourth bonding surface 214 is placed in the pressure-keeping distance between the support plate 523 and the pressure-keeping plate 522 in the left-right direction. The supporting plate 523 and the pressure-maintaining plate 522 squeeze the fitting portion so that the folded portions of the connecting portion 210 will not separate from each other or become debonded before the connecting portion 210 is conveyed to the discharge port, thereby improving the production efficiency of the handle 200.

[0056] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
