Summary of the Invention
Problems to be Solved by the Invention
[0004] However, when the automatic conveyance facility fails (such as a power outage), it is difficult for an operator to manually take out articles from the article placement shelf installed at a high place, and the weight of the articles often cannot be easily manually conveyed by the operator.
Means for Solving the Problems
[0005] The present invention provides an article placement shelf and a lifter that can easily take out articles by the operation of an operator.
[0006] The article placement shelf for placing articles of the present invention includes a frame member and a shelf board member installed on the frame member for placing the articles. At least one pair of engaging portions protruding toward the frame member are provided on the shelf board member. The frame member is provided with at least one pair of engaged portions protruding toward the shelf board member and corresponding to the engaging portions. The engaging portion engages with the engaged portion from above to below in the vertical direction to constitute an engaged state between the shelf board member and the frame member. The connection line of the at least one pair of engaged portions constitutes an engaging direction, and the shelf board member moves in an engaging release direction perpendicular to the engaging direction in the horizontal plane to release the engaged state with the frame member.
[0007] The lifter for taking out articles on the article placement shelf of the present invention includes a cart portion movable in a horizontal plane constituted by the front-rear direction and the left-right direction, a lifting portion installed on the cart portion and movable in the vertical direction, a placement portion installed on the lifting portion for placing the shelf board member on which the articles of the article placement shelf are placed, and a slide portion installed between the placement portion and the lifting portion for making the placement portion movable relative to the lifting portion in the horizontal plane. The placement portion moves in the vertical direction through the lifting portion to place the shelf board member on which the articles are placed below the article placement shelf, and the placement portion moves in the horizontal direction through the slide portion to take out the shelf board member and the articles together.
Advantages of the Invention
[0008] Based on the above, in the article placement shelf of the present invention, the shelf board member moves in the engagement release direction perpendicular to the engagement direction in the horizontal plane to release the engagement state with the frame member. Correspondingly, in the lifter of the present invention, the placement part moves horizontally through the slide part to take out the shelf board member and the articles together. In this way, when the automatic conveying equipment fails (such as a power outage), the articles on the article placement shelf installed at a high place or relatively heavy articles can be easily taken out through the article placement shelf and the lifter of the present invention. Thereby, the article placement shelf and the lifter of the present invention can easily take out the articles by the operation of the operator.

Modes for Carrying Out the Invention
[0010] Here, exemplary embodiments of the present invention will be referred to in detail, and examples of the exemplary embodiments will be shown in the drawings. Among them, FIG. 1 is a perspective explanatory view of an article placement shelf according to an embodiment of the present invention, FIG. 2 is a perspective explanatory view of placing an article in one placement area of the article placement shelf shown in FIG. 1, FIG. 3 is a partially enlarged explanatory view of one placement area of the article placement shelf shown in FIG. 1, FIG. 4 is an exploded explanatory view of one placement area of the article placement shelf shown in FIG. 3, FIG. 5 is an operation explanatory view of the application of the lifter to taking out an article on the article placement shelf according to an embodiment of the present invention, and FIG. 6 is a perspective explanatory view of the placement part used in the lifter shown in FIG. 5. Hereinafter, with reference to FIGS. 1 to 6, the article placement shelf 100 and the lifter 200 of this embodiment will be described, and the spatial coordinate system XYZ will be described as the front-rear direction X, the left-right direction Y, and the up-down direction Z. However, this is only an example of the present invention and does not limit the present invention thereto.
[0011] Referring to FIGS. 1 and 2, in this embodiment, the article placement shelf 100 for placing the article 50 is an article placement shelf installed at a high place, for example, a hanging shelf installed on the ceiling C, and the article 50 can be transported to or taken out from the hanging type article placement shelf 100 by an automatic conveying facility (not shown). In this way, the upper space of the building (that is, near the ceiling C) can be effectively utilized to store articles, and by combining the automatic conveying facility with the article placement shelf 100, automatic management (storage or taking out) of the article 50 can be performed, and the management of the article 50 can be made more efficient. However, when the automatic conveying facility fails (such as a power outage), it is difficult for the operator to manually take out the article 50 from the article placement shelf 100 installed at a high place, and the weight of the article 50 often cannot be easily manually transported by the operator. In contrast, the article placement shelf 100 has a structural arrangement as described below, and the article 50 can be easily taken out by the operation of the operator.
[0012] Specifically, in the present embodiment, as shown in FIGS. 1 and 2, the article placement shelf 100 includes a frame member 110 and a shelf board member 120. The frame member 110 is composed of a plurality of stays. For example, it includes a plurality of vertical stays 112 installed on the ceiling C and extending in the vertical direction Z (i.e., the direction of gravity), and a plurality of horizontal stays 114 forming an arrangement region R on the horizontal plane. The shelf board member 120 is installed on the frame member 110. For example, it is installed in the arrangement region R of the frame member 110 to place the article 50. Here, the frame member 110 of the article placement shelf 100 forms a plurality of arrangement regions R (three in the example), and a plurality of shelf board members 120 (three in the example) are correspondingly provided in the plurality of arrangement regions R, so that one or more articles 50 can be correspondingly placed. For example, one article 50 can be correspondingly placed on one shelf board member 120 (see FIG. 2), and the other shelf board members 120 may be empty without articles placed thereon, or a plurality of articles can be placed on the same shelf board member 120, or some of the shelf board members 120 can all have articles correspondingly placed thereon. Also, the frame member 110 may form only one arrangement region R and only one shelf board member 120 may be arranged on the frame member 110. The present invention does not limit the specific structures of the frame member 110 and the shelf board member 120, nor does it limit the application of the article 50, and can be adjusted as needed.
[0013] Also, in this embodiment, one arrangement region R of the article placement shelf 100 is described as an example. As shown in FIGS. 3 and 4, at least one pair (for example, two pairs) of engaging portions 122 protruding toward the frame member 110 are provided on the shelf board member 120, and at least one pair (for example, two pairs) of engaged portions 116 protruding toward the shelf board member 120 and corresponding to the engaging portions 122 are provided on the frame member 110. That is, the shelf board member 120 is arranged in the arrangement region R formed by the frame member 110 and is located inside the frame member 110. Therefore, at least one pair of engaging portions 122 protruding toward the frame member 110 of the shelf board member 120 preferably extend outward from both opposite ends (for example, both opposite ends in the left-right direction Y) of the shelf board member 120, and at least one pair of engaged portions 116 protruding toward the shelf board member 120 of the frame member 110 preferably extend inward from the frame member 110. Accordingly, the engaging portions 122 of the shelf board member 120 engage with the engaged portions 116 from above to below in the vertical direction (that is, the vertical direction Z) to constitute the engaged state of the shelf board member 120 and the frame member 110. Therefore, the shelf board member 120 is restricted to the horizontal plane where the arrangement region R of the frame member 110 is located. In this case, the connection line of at least one pair of engaged portions 116 constitutes the engaging direction (here, it is parallel to the left-right direction Y, but is not limited thereto).
[0014] Furthermore, in the present embodiment, as shown in FIG. 3, the shelf board member 120 includes a pair of frames 124 extending along the engagement direction (here, parallel to the left-right direction Y), and a plate body 126 installed above the pair of frames 124 (here, parallel to the horizontal plane composed of the front-rear direction X and the left-right direction Y, but not limited thereto). The length of the frame 124 in the engagement direction (here, parallel to the left-right direction Y) is longer than the length of the plate body 126 in the engagement direction, and engagement portions 122 protruding toward the frame member 110 are formed at both opposite ends of the frame 124. Also, as shown in FIG. 4, since the engaged portion 116 is formed as a convex portion protruding from the inner surface of the frame member 110 toward the shelf board member 120 along the engagement direction (here, parallel to the left-right direction Y), when the shelf board member 120 is placed on the frame member 110 from above in the up-down direction (i.e., the up-down direction Z), the engagement portion 122 of the shelf board member 120 engages with the engaged portion 116 from above in the up-down direction (i.e., the up-down direction Z), constituting the engaged state of the shelf board member 120 and the frame member 110. Therefore, the lower part of the shelf board member 120 is supported by the frame member 110, the upper part of the shelf board member 120 can place the article 50, and the weight of the article 50 is dispersed from the shelf board member 120 to the frame member 110. The article 50 can be conveyed to or taken out from the suspended article placement shelf 100 via an automatic conveyance facility (not shown), and the article 50 is placed on the shelf board member 120 from above in the up-down direction (i.e., the up-down direction Z).
[0015] Also, in the present embodiment, the direction perpendicular to the engagement direction (here, parallel to the left-right direction Y) in the horizontal plane is defined as the disengagement direction (here, parallel to the front-back direction X, but not limited thereto). When the engaging portion 122 of the shelf plate member 120 engages with the engaged portion 116 from above in the vertical direction (i.e., the up-down direction Z), the shelf plate member 120 moves in the disengagement direction (here, parallel to the front-back direction X) which is perpendicular to the engagement direction (here, parallel to the left-right direction Y) in the horizontal plane (arrow A shown in FIG. 3), and the engagement state with the frame member 110 can be released. That is, the shelf plate member 120 and the frame member 110 can engage or release the engagement state as required.
[0016] Specifically, in the present embodiment, as shown in FIG. 4, at least a part of the engaging portion 122 is formed in an inverted U-shape such that the engaging portion 122 engages with the engaged portion 116 (e.g., a convex portion) from above in the vertical direction (i.e., the up-down direction Z). For example, the inverted U-shaped portion of the engaging portion 122 covers the engaged portion 116. Further, a convex column 116a is provided on the upper surface of the engaged portion 116 in the vertical direction (i.e., the up-down direction Z), an opening 122a is provided on the upper surface of the engaging portion 122 in the vertical direction (i.e., the up-down direction Z), and the convex column 116a of the engaged portion 116 passes through the opening 122a of the engaging portion 122 such that the engaging portion 122 engages with the engaged portion 116 (e.g., a convex portion) from above in the vertical direction (i.e., the up-down direction Z). In this way, the shelf plate member 120 and the frame member 110 engage not only in the engagement direction (here, parallel to the left-right direction Y), but also in the direction perpendicular to the engagement direction in the horizontal plane (here, parallel to the front-back direction X). Therefore, the fixing effect of the shelf plate member 120 and the frame member 110 is improved, and the article 50 can be placed more stably.
[0017] Therefore, when the article 50 cannot be taken out from above the article placement shelf 100 using the automatic conveying equipment, for example, when the automatic conveying equipment breaks down (such as a power outage), as one method of taking out the article 50, preferably, the shelf board member 120 moves upward from below in the vertical direction (i.e., the vertical direction Z) and in the disengagement direction, releases the engagement state with the frame member 110, and thereby takes out the shelf board member 120 and the article 50 placed on the shelf board member 120 together. That is, the operator uses a tool (for example, a lifter described later, but not limited thereto) to support the shelf board member 120 from below the shelf board member 120, moves the shelf board member 120 upward from below in the vertical direction (i.e., the vertical direction Z), first releases the engagement relationship between the inverted U-shaped portion of the engaging portion 122 and the engaged portion 116 (for example, a convex portion), and also releases the engagement relationship between the opening 122a of the engaging portion 122 and the convex column 116a of the engaged portion 116. Then, the shelf board member 120 moves in the disengagement direction (here, parallel to the front-rear direction X) (arrow A shown in FIG. 3), thereby releasing the engagement state between the shelf board member 120 and the frame member 110, and taking out the shelf board member 120 and the article 50 placed on the shelf board member 120 together. At this time, since at least one pair of engaged portions 116 are respectively installed on the inner surface of the frame member 110 and are not connected to each other (see FIG. 4), at least one pair of engaged portions 116 do not interfere with the movement of the tool in the disengagement direction (here, parallel to the front-rear direction X). In this way, even for the article placement shelf 100 installed at a high place or the article 50 with a relatively heavy weight, the above arrangement method of the article placement shelf 100 (in particular, the arrangement of the shelf board member 120 movable in the disengagement direction) can assist the operator to easily take out the article 50.
[0018] However, the method of taking out the above-mentioned article 50 is only one of the exemplary explanations made according to the structure of the article placement shelf 100. In other embodiments not shown, the engaging method of the engaging portion 122 and the engaged portion 116 may only adopt the inverted U-shaped portion, and it is not necessary to provide the combination of the opening 122a and the convex column 116a. Or only the combination of the opening 122a and the convex column 116a may be adopted, and it is not necessary to provide the inverted U-shaped portion. Alternatively, a U-shaped portion may be provided on the convex portion as the engaged portion 116, and the engaging portion 122 may be placed in the U-shaped portion of the convex portion as the engaged portion 116 and engaged with the engaged portion 116. As one of the methods of taking out the article 50 in the above structure, the method described above can be referred to, that is, the shelf board member 120 moves from below to above in the vertical direction (i.e., the vertical direction Z) and in the disengaging direction (here, parallel to the front-rear direction X), but the present invention is not limited thereto.
[0019] Furthermore, in other embodiments not shown, the engaging portion 122 and the engaged portion 116 do not necessarily need to be provided with an inverted U-shaped portion and the combination of the opening 122a and the convex column 116a. As an alternative method, although not preferred, the engaging portion 122 of the shelf board member 120 is placed on the upper surface of the engaged portion 116 from above to below in the vertical direction (i.e., the vertical direction Z), and the two are engaged by frictional force to constitute the engaged state of the shelf board member 120 and the frame member 110. At this time, as one of the methods of taking out the article 50 in the above structure, preferably, the shelf board member 120 moves in the disengaging direction (here, parallel to the front-rear direction X) to release the engaged state with the frame member 110. That is, when the shelf board member 120 and the frame member 110 are engaged only in the engaging direction (here, parallel to the left-right direction Y) and not engaged in the direction perpendicular to the horizontal plane in the engaging direction (here, parallel to the front-rear direction X), the shelf board member 120 only needs to move in the disengaging direction, and it is not limited whether the shelf board member 120 moves from below to above in the vertical direction (i.e., the vertical direction Z), and can be adjusted as needed. In this way, for the article placement shelves 100 with different structures, as long as the shelf board member 120 of the article placement shelf 100 can move in the disengaging direction, the article 50 can be easily taken out.
[0020] Further, in the present embodiment, as shown in FIGS. 3 and 4, a spacer 130 may be provided between the engaging portion 122 and the frame member 110. When there may be a gap between the engaging portion 122 and the frame member 110 due to a tolerance or a design requirement, the spacer 130 restricts the movement of the shelf plate member 120 relative to the frame member 110 in the engaging direction. That is, after the engaging portion 122 of the shelf plate member 120 engages with the engaged portion 116 from above in the vertical direction (i.e., the vertical direction Z), the spacer 130 can be inserted between the engaging portion 122 and the frame member 110 as needed (see FIG. 3). Further, when the spacer 130 is provided, the spacer 130 can be removed from between the engaging portion 122 and the frame member 110 by moving it in the disengaging direction (here, parallel to the front-rear direction X) (see FIG. 4), making it easier for the shelf plate member 120 to move in the disengaging direction (here, parallel to the front-rear direction X). However, the present invention is not limited to the presence or absence of the installation of the spacer 130 and can be adjusted as needed.
[0021] Next, referring to FIGS. 5 and 6, in the present embodiment, the lifter 200 for taking out the article 50 on the article placement shelf 100 includes a cart portion 210, a lifting portion 220, a placement portion 230, and a slide portion 240. Here, the article placement shelf 100 is, for example, the above-described suspended article placement shelf, but is not limited thereto. Further, in the lifter 200, the cart portion 210 is movable on a horizontal plane (for example, the ground G) constituted by the front-rear direction X and the left-right direction Y. The lifting portion 220 is installed on the cart portion 210 and is movable in the vertical direction Z. The placement portion 230 is installed on the lifting portion 220 and places the shelf board member 120 on which the article 50 of the article placement shelf 100 is placed. The slide portion 240 is installed between the placement portion 230 and the lifting portion 220, and the placement portion 230 is movable relative to the lifting portion 220 on a horizontal plane (for example, the plane where the placement portion 230 is located). The movement includes moving along the front-rear direction X, moving along the left-right direction Y, or rotating in the rotation direction θ on the horizontal plane, but is not limited thereto. Therefore, the lifter 200 has a function of moving the placement portion 230 in four axial directions, namely, the front-rear direction X, the left-right direction Y, the vertical direction Z, and the rotation direction θ. The placement portion 230 moves in the vertical direction Z via the lifting portion 220 (which has a function of moving in the vertical direction Z), places the shelf board member 120 on which the article 50 is placed below the article placement shelf 100, and the placement portion 230 moves horizontally (for example, the above-described engagement release direction, and here, parallel to the front-rear direction X) via the slide portion 240 (which has a function of moving in the front-rear direction X, the left-right direction Y, and the rotation direction θ), and takes out the shelf board member 120 and the article 50 placed on the shelf board member 120 together.
[0022] Specifically, in the present embodiment, as shown in FIG. 5, since a plurality of wheels 212 are provided below the carriage portion 210, the carriage portion 210 is movable on a horizontal plane (for example, the ground G) configured in the front-rear direction X and the left-right direction Y. However, the present invention does not limit the specific structure and moving means of the carriage portion 210. The lifting portion 220 includes a lifting means 222 movable in the vertical direction Z and a lifting handle 224 that drives the vertical movement of the lifting means 222 in the vertical direction Z by rotation. Therefore, an operator can operate the lifting means 222 via the lifting handle 224, thereby controlling the vertical movement of the lifting portion 220 in the vertical direction Z. Similarly, the slide portion 240 includes a slide means 242 movable on a horizontal plane (for example, the plane where the placement portion 230 is located) and a slide handle 244 that drives the movement of the slide means 242 on the horizontal plane by rotation. Therefore, an operator can operate the slide means 242 via the slide handle 244, thereby controlling the movement of the slide portion 240 on the horizontal plane. Here, the purpose of providing the slide portion 240 is to drive the placement portion 230 to move in the horizontal direction (for example, the above-described engagement release direction, and here, parallel to the front-rear direction X) to take out the shelf board member 120 and the articles 50 placed on the shelf board member 120 together. However, since the slide portion 240 has functions of moving in the front-rear direction X, the left-right direction Y, and the rotation direction θ, the position of the placement portion 230 can be finely adjusted through the movement of the slide portion 240 in the left-right direction Y and the rotation direction θ. However, in other embodiments not shown, other means may be used as the lifting portion 220 and the slide portion 240, and the movement of the lifting portion 220 and the slide portion 240 may be automatically controlled using automated means. The present invention is not limited thereto.
[0023] Also, in the present embodiment, as shown in FIGS. 5 and 6, the placement portion 230 is provided with a placement surface 232 for placing the shelf board member 120 on which the article 50 of the article placement shelf 100 is placed, a protrusion 234 installed around the placement surface 232, and a notch 236 installed around the placement surface 232 and adjacent to the protrusion 234. Here, the protrusion 234 is provided with an inclined surface 234a that inclines inward from top to bottom. When the placement portion 230 places the shelf board member 120 on which the article 50 is placed below the article placement shelf 100, the protrusion 234 can pass through the gap S between the shelf board member 120 and the frame member 110 of the article placement shelf 100 (see FIG. 3), and guides the position of the shelf board member 120 on the placement surface 232 via the inclined surface 234a. Further, when the placement portion 230 places the shelf board member 120 on which the article 50 is placed below the article placement shelf 100, the engaging portions 122 provided at both opposite ends of the shelf board member 120 protrude outside the placement surface 232 through the notch 236 and do not interfere with the protrusion 234. That is, the protrusions 234 installed around the placement surface 232 do not surround the entire outer periphery of the placement surface 232, but a plurality of protrusions 234 are separately installed, thereby forming a notch 236 between two adjacent protrusions 234. However, the present invention does not limit the specific structures and presence or absence of installation of the protrusion 234 and the notch 236, and can be adjusted as necessary.
[0024] Therefore, when it is impossible to take out the article 50 from above the article placement shelf 100 using the automatic conveying equipment, for example, when the automatic conveying equipment breaks down (such as a power outage), or when the engaging method between the engaging portion 122 and the engaged portion 116 of the article placement shelf 100 adopts the reverse U-shaped portion and / or the combination of the opening 122a and the convex column 116a described above, as one of the methods for taking out the article 50, preferably, the operator uses the lifter 200 to drive the shelf board member 120 to move upward from below in the vertical direction (i.e., the vertical direction Z) and in the disengaging direction (here, parallel to the front-rear direction X), and releases the engaged state with the frame member 110, thereby taking out the shelf board member 120 and the article 50 placed on the shelf board member 120 together. That is, the operator uses the lifter 200 to support the shelf board member 120 from below the shelf board member 120, moves the shelf board member 120 upward from below in the vertical direction (i.e., the vertical direction Z), first releases the engagement relationship between the reverse U-shaped portion of the engaging portion 122 and the engaged portion 116 (for example, the convex portion), and also releases the engagement relationship between the opening 122a of the engaging portion 122 and the convex column 116a of the engaged portion 116, and then moves the shelf board member 120 in the disengaging direction (here, parallel to the front-rear direction X) (arrow A shown in FIG. 3), thereby releasing the engaged state between the shelf board member 120 and the frame member 110, and taking out the shelf board member 120 and the article 50 placed on the shelf board member 120 together.
[0025] More specifically, in this process, the lifter 200 moves below the article placement shelf 100 using the carriage part 210, moves the placement part 230 below the shelf board member 120 using the lifting part 220, supports the shelf board member 120 from below the shelf board member 120 on the placement part 230, moves the shelf board member 120 upward from below in the vertical direction (i.e., the vertical direction Z), first releases the engagement relationship between the inverted U-shaped part of the engaging part 122 and the engaged part 116 (e.g., a convex part), and also releases the engagement relationship between the opening 122a of the engaging part 122 and the convex column 116a of the engaged part 116. Then, the placement part 230 is moved horizontally using the slide part 240. At this time, the lifter 200 is set such that the horizontal direction corresponds to the disengagement direction of the article placement shelf 100. Thereby, the horizontal movement of the placement part 230 moves the shelf board member 120 in the disengagement direction (here, parallel to the front-rear direction X) (arrow A shown in FIG. 3). Therefore, the engagement state between the shelf board member 120 and the frame member 110 is released, and the shelf board member 120 and the article 50 placed on the shelf board member 120 are taken out together. In this way, even for the article placement shelf 100 installed at a high place or the article 50 with a relatively heavy weight, the above arrangement method of the article placement shelf 100 (especially the arrangement of the shelf board member 120 movable in the disengagement direction) and the above arrangement method of the lifter 200 (especially the arrangement of the slide part 240 capable of moving the placement part 230 horizontally) can assist the operator in easily taking out the article 50.
[0026] However, the method by which the above lifter 200 takes out the article 50 is only one of the exemplary descriptions made according to the structure of the article placement shelf 100. In other embodiments not shown, the engaging portion 122 and the engaged portion 116 do not necessarily need to be provided with a combination of an inverted U-shaped portion and an opening 122a and a convex column 116a. The engaging portion 122 may only be placed on the upper surface of the engaged portion 116, and the two may be engaged by frictional force to constitute the engaged state of the shelf board member 120 and the frame member 110. At this time, as one of the methods for the lifter 200 to take out the article 50 in the above structure, preferably, the lifter 200 supports the shelf board member 120 from below the shelf board member 120, moves the shelf board member 120 in the disengaging direction (here, parallel to the front-rear direction X), and releases the engaged state with the frame member 110. That is, when the shelf board member 120 and the frame member 110 are engaged only in the engaging direction (here, parallel to the left-right direction Y) and not in the direction perpendicular to the engaging direction in the horizontal plane (here, parallel to the front-rear direction X), the shelf board member 120 only needs to move in the disengaging direction, and it is not limited whether the shelf board member 120 moves upward from below in the vertical direction (that is, the up-down direction Z), and can be adjusted as needed. In this way, for the article placement shelves 100 with different structures, as long as the shelf board member 120 of the article placement shelf 100 can move in the disengaging direction, the article 50 can be easily taken out using the lifter 200 having the above arrangement method.
[0027] Based on the above, in the article placement shelf of the present invention, the shelf board member moves in the engagement release direction perpendicular to the engagement direction in the horizontal plane, and releases the engagement state with the frame member. Correspondingly, in the lifter of the present invention, the placement part moves horizontally through the slide part, and takes out the shelf board member and the article together. In this way, when the automatic conveying equipment fails (such as a power outage), the article placement shelf installed at a high place or an article with a relatively heavy weight can be easily taken out through the article placement shelf and the lifter of the present invention. Also, for article placement shelves with different structures, as long as the shelf board member of the article placement shelf can move in the engagement release direction, the article can be easily taken out by using the lifter having the above arrangement method. Thereby, the article placement shelf and the lifter of the present invention can easily take out the article by the operation of the operator.
[0028] Finally, it should be noted that the above embodiments are only used for the description of the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can naturally understand that the technical solutions described in the above embodiments can still be modified, or equivalent replacements can be made for some or all of the technical features. However, these modifications or replacements do not deviate from the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
