Description

Technical Field

[0001] The present disclosure relates to an assembly for an edge detection device. Background Art

[0002] In the production process of cigarette products, especially in the tobacco warehouse, automatic guided vehicles (AGVs), especially AGV forklifts, are often used to place cigarette boxes. The AGV forklift can usually place the cigarette boxes in multiple rows and columns using its forks.

[0003] However, when stacking cigarette boxes up and down using an AGV forklift, the cigarette boxes are often placed crookedly. One important reason is that the edge detection device used to detect the edge position of the cigarette box is crooked.

[0004] When using an AGV forklift to stack cigarette boxes, the AGV forklift usually places them according to the detection results of the edge detection device used to detect the edge position of the cigarette box. Therefore, before using the AGV forklift to place the cigarette box, the edge detection device is usually calibrated to ensure that the detection rays of the edge detection device are irradiated vertically downward, so that the edge of the object directly below can be detected. In this way, it can be ensured that when using the AGV forklift to stack cigarette boxes, the AGV forklift can stack the cigarette boxes neatly without deviation.

[0005] However, at present, although the fixing method of the edge detection device on the fork of the AGV forklift is convenient for calibrating the edge detection device, this fixing method is not stable. For example, since the fork of the AGV forklift is easily hit by the cigarette box next to it during the process of picking up and placing the cigarette box, the edge detection device fixed on the fork may be offset, resulting in the inability to stack the cigarette boxes neatly when the AGV forklift is used to put the cigarette boxes into storage. If the untidy stacked cigarette boxes are not discovered in time, there is a risk of the cigarette boxes falling. Even if crookedly stacked cigarette boxes are found, it may take a lot of time to adjust the position of the cigarette boxes because the positions of some cigarette boxes are difficult to correct (this is because the cigarette boxes are placed in rows, and there are multiple columns of cigarette boxes in a row).

[0006] Therefore, it is necessary to develop an assembly assembly for an edge detection device to prevent the edge detection device from being skewed, for example, due to impact. Utility Model Content

[0007] In view of this, the purpose of the present disclosure is to provide an assembly assembly for an edge detection device, which can at least reduce or even eliminate the possibility of positional displacement of the edge detection device, for example, due to impact, etc. At the same time, the assembly assembly can also enable the edge detection device to be conveniently adjusted for calibration.

[0008] One aspect of the present disclosure relates to an assembly component for an edge detection device, wherein the assembly component is capable of adjustably assembling the edge detection device on the side of an object, and is characterized in that the assembly component includes: a support plate, the support plate is constructed as a U-shaped support plate and has a first leg plate and a second leg plate and a first connecting plate connecting the first leg plate and the second leg plate, and the edge detection device can be fixedly connected to the first connecting plate of the support plate; and a protective cover, the protective cover is constructed as a U-shaped support plate and has a third leg plate and a fourth leg plate and a second connecting plate connecting the third leg plate and the fourth leg plate, and the free ends of the third leg plate and the fourth leg plate are respectively connected with a first flange plate and a second flange plate, the first flange plate and the second flange plate extend in the same plane and extend parallel to the second connecting plate, the protective cover can be fixedly connected to the side of the object using the first flange plate and / or the second flange plate, wherein the protective cover can be externally sleeved on the support plate so that the first leg plate and the second leg plate of the support plate are respectively adjacent to the third leg plate and the fourth leg plate of the protective cover and can be adjustably connected to each other.

[0009] Therefore, when the edge detection device is assembled on the side of an object using the assembly assembly according to the present disclosure, since the protective cover can be externally mounted on the support plate, the support plate carrying the edge detection device will not be directly exposed to the surrounding environment, thereby greatly reducing the possibility of the support plate being affected by the surrounding environment. Therefore, for example, when the fork of the AGV forklift is hit by the cigarette box next to it during the process of picking up and placing the cigarette box, the possibility of the edge detection device assembled on the fork being displaced is at least reduced or eliminated. At the same time, since the support plate carrying the edge detection device and the protective cover are adjustably connected to each other, the assembly assembly can also make the edge detection device conveniently adjusted for calibration.

[0010] In some embodiments, the edge detection device is fixedly connected to the first connecting plate of the support plate by bolts, and a first hole for the bolts to pass through is provided in the first connecting plate of the support plate, thereby simply realizing the fixed connection between the edge detection device and the support plate.

[0011] In some embodiments, a first corresponding hole aligned with the first hole on the first connecting plate is provided in the second connecting plate of the protective cover, and the area of ​​the first corresponding hole is larger than the area of ​​the first hole, thereby facilitating tightening the bolts connecting the edge detection device and the support plate from the outside.

[0012] In some embodiments, the protective cover can be fixedly connected to the side of the object by bolts using the first flange plate, and flange plate holes for the bolts to pass through are provided in the first flange plate, thereby making it easy to achieve a fixed connection between the protective cover and the object.

[0013] In some embodiments, the first flange plate extends toward between the third leg plate and the fourth leg plate of the protective cover; the first supporting plate corresponding hole and the first protective cover corresponding hole aligned with the flange plate hole are respectively provided in the first connecting plate of the supporting plate and the second connecting plate of the protective cover, and the area of ​​the first supporting plate corresponding hole and the first protective cover corresponding hole are both larger than the area of ​​the flange plate hole. This makes it easy to tighten the bolts connecting the protective cover and the object from the outside.

[0014] In some embodiments, the protective cover can be adjustably connected to the side of the object by bolts using the second flange plate, and the second flange plate is provided with a first long hole for the bolts to pass through. This makes it easy to achieve an adjustable connection between the protective cover and the object, especially in the direction of the long axis of the first long hole.

[0015] In some embodiments, the second flange plate extends toward between the third leg plate and the fourth leg plate of the protective cover; a second supporting plate corresponding hole aligned with the first long hole and a second protective cover corresponding hole are respectively provided in the first connecting plate of the supporting plate and the second connecting plate of the protective cover, and the area of ​​the second supporting plate corresponding hole and the second protective cover corresponding hole are both larger than the area of ​​the first long hole. This makes it easier to tighten the bolts connecting the protective cover and the object from the outside.

[0016] In some embodiments, the long axis of the first long hole extends parallel to the side of the object. Thus, the relative position of the protective cover and the object can be adjusted in the vertical direction, and thus the relative position of the edge detection device relative to the object can be adjusted.

[0017] In some embodiments, the first leg plate and the second leg plate of the support plate can be connected to the third leg plate and the fourth leg plate of the protective cover respectively by bolts and nuts, and the first leg plate and the second leg plate of the support plate are provided with second holes for the bolts to pass through, and the third leg plate and the fourth leg plate of the protective cover are provided with second long holes for the bolts to pass through. In this way, the adjustable connection between the support plate and the protective cover can be simply realized.

[0018] In some embodiments, the long axis of the second long hole extends perpendicular to the side of the object. Thus, the relative position of the support plate and the protective cover can be adjusted in the horizontal direction and thus the relative position of the edge detection device relative to the object can be adjusted.

[0026] As mentioned at the beginning of this article, AGV forklifts are often used to place cigarette boxes in the production process of cigarette products, especially in tobacco warehouses. AGV forklifts usually place cigarette boxes according to the detection results of edge detection devices used to detect the edge positions of cigarette boxes. In particular, when using AGV forklifts to stack cigarette boxes up and down, the edge detection device will emit detection rays pointing vertically downward for detection. For this reason, before using AGV forklifts to place cigarette boxes, the edge detection device is usually calibrated to ensure that the detection rays of the edge detection device are irradiated vertically downward. However, if the edge detection device is skewed when the AGV forklift moves, the detection rays emitted at the edge detection position will also be skewed, resulting in errors in the detection results, which makes it impossible to stack the cigarette boxes neatly when using AGV forklifts to put the cigarette boxes into storage.

[0027] At present, the edge detection device is usually adjustably connected to an L-shaped bracket by means of a support plate, and the L-shaped bracket is fixedly connected to the side of the fork of the AGV forklift. In this fixing method of the edge detection device, the support plate carrying the edge detection device is directly exposed to the surrounding environment. Therefore, for example, when the fork of the AGV forklift is hit by the cigarette box next to it during the process of taking and placing the cigarette box, the edge detection device mounted on the fork will easily shift its position, thereby causing errors in the detection results. Therefore, in view of the problem that the edge detection device mounted on the AGV forklift used in the existing tobacco warehouse is prone to position shift, the present disclosure is dedicated to providing an assembly component that can protect the edge detection device to prevent the edge detection device from shifting its position, and at the same time, the edge detection device can be adjusted and calibrated by using the assembly component as needed without disassembling the assembly component.

[0028] Refer to the following Figure 1 , Figures 2A-2C as well as Figures 3A-3C An assembly component for an edge detection device according to an embodiment of the present disclosure is described.

[0029] First refer to Figure 1 According to the embodiment of the present disclosure, the assembly assembly 30 for the edge detection device 20 can adjustably assemble the edge detection device 20 on the side 11 of the object. The object in this embodiment is the fork 10 of the AGV forklift. When the detection device 20 is assembled on the side 11 of the fork 10 using the assembly assembly 30, the edge detection device 20 can emit a vertical downward (i.e., at the edge of the object). Figure 1 In addition, it can be seen that the cable 21 for the edge detection device 20 can extend from the assembly component 30 through the hole of the assembly component 30.

[0030] The assembly component 30 according to an embodiment of the present disclosure may include a support plate 100 and a protection cover 200 .

[0031] Continue to refer to Figure 1 Also refer to Figures 2A-2C The support plate 100 may be configured as a U-shaped support plate and may therefore have a first leg plate 120 and a second leg plate 130 and a first connecting plate 110 connecting the first leg plate 120 and the second leg plate 130. The edge detection device 20 may be fixedly connected to the first connecting plate 110 of the support plate 100.

[0032] Continue to refer to Figure 1 Also refer to Figures 3A-3C , the protective cover 200 can be configured as a U-shaped support plate and has a third leg plate 220 and a fourth leg plate 230 and a second connecting plate 210 connecting the third leg plate 220 and the fourth leg plate 230. In addition, the first flange plate 240 and the second flange plate 250 are connected to the free ends of the third leg plate 220 and the fourth leg plate 230, respectively. In addition, it can also be noted that the first flange plate 240 and the second flange plate 250 extend in the same plane and extend parallel to the second connecting plate 210. The protective cover 200 can be fixedly connected to the side of the object 10 using the first flange plate 240 and / or the second flange plate 250.

[0033] Especially if Figure 1 As shown, the protective cover 200 can be externally mounted on the support plate 100, so that the first leg plate 120 and the second leg plate 130 of the support plate 100 are respectively adjacent to the third leg plate 220 and the fourth leg plate 230 of the protective cover 200 and can be adjustably connected to each other. It can also be seen that the first connecting plate 110 and the second connecting plate 210 can extend parallel to each other at a distance.

[0034] Therefore, when the edge detection device 20 is assembled on the side 11 of the fork 10 using the assembly assembly 30, since the protective cover 200 can be externally mounted on the support plate 100, the support plate 100 carrying the edge detection device 20 will not be directly exposed to the surrounding environment, thereby greatly reducing the possibility that the support plate 100 is affected by the surrounding environment. In addition, since the first connecting plate 110 and the second connecting plate 210 are spaced apart, the influence of the external protective cover 200 has a smaller effect on the internal support plate 100 and the edge detection device 20 fixed thereon. Therefore, for example, when the fork of the AGV forklift is hit by a cigarette box next to it during the process of picking up and placing a cigarette box, the possibility of the edge detection device assembled on the fork being offset is at least reduced or eliminated.

[0035] According to some embodiments of the present disclosure, in particular, referring to Figure 1 and Figures 2A-2C, the edge detection device 20 can be fixedly connected to the first connection plate 110 of the support plate 100 by bolts (not shown). To this end, a first hole 111 for the bolt to pass through can be provided in the first connection plate 110 of the support plate 100. In this way, the fixed connection between the edge detection device 20 and the support plate 100 can be simply achieved.

[0036] In this regard, preferably, in particular with reference to Figure 1 and Figures 3A-3C , a first corresponding hole 211 aligned with the first hole 111 on the first connecting plate 110 may be provided in the second connecting plate 210 of the protective cover 200. The area of ​​the first corresponding hole 211 may be larger than the area of ​​the first hole 111. This makes it easier to tighten the bolts connecting the edge detection device 20 and the support plate 100 from the outside.

[0037] In the illustrated embodiment, the edge detection device 20 can be fixedly connected to the first connection plate 110 of the support plate 100 by two bolts and corresponding two first holes 111 and corresponding two first corresponding holes 211. However, it is conceivable that the edge detection device 20 can be fixedly connected to the first connection plate 110 of the support plate 100 at an appropriate position by any number of bolts and corresponding number of first holes 111 and corresponding number of first corresponding holes 211 as required.

[0038] According to some embodiments of the present disclosure, in particular, referring to Figure 1 and Figures 3A-3C The protective cover 200 can be fixedly connected to the side surface 11 of the fork 10 by means of a first flange plate 240 through bolts (not shown). To this end, a flange plate hole 241 for the bolts to pass through can be provided in the first flange plate 240. In this way, the protective cover 200 can be simply fixedly connected to the fork 10.

[0039] In this regard, preferably, in particular with reference to Figure 1 and Figures 3A-3C When the first flange plate 240 extends toward between the third leg plate 220 and the fourth leg plate 230 of the protective cover 200, the first supporting plate corresponding hole 112 and the first protective cover corresponding hole 212 aligned with the flange plate hole 241 may be respectively provided in the first connecting plate 110 of the supporting plate 100 and the second connecting plate 210 of the protective cover 200. The areas of the first supporting plate corresponding hole 112 and the first protective cover corresponding hole 212 may be larger than the area of ​​the flange plate hole 241. This makes it easier to tighten the bolts connecting the protective cover 200 and the fork 10 from the outside.

[0040] In the illustrated embodiment, the protective cover 200 can be fixedly connected to the side 11 of the fork 10 by two bolts and corresponding two flange plate holes 241 and corresponding two first support plate corresponding holes 112 and corresponding two first protective cover corresponding holes 212. However, it is conceivable that the protective cover 200 can be fixedly connected to the side 11 of the fork 10 at an appropriate position by any number of bolts and corresponding number of flange plate holes 241 and corresponding number of first support plate corresponding holes 112 and corresponding number of first protective cover corresponding holes 212 as required.

[0041] According to some embodiments of the present disclosure, in particular, referring to Figure 1 and Figures 3A-3C The protective cover 200 can be adjustably connected to the side surface 11 of the fork 10 by means of bolts (not shown) using the second flange plate 250. For this purpose, a first long hole 251 for the bolt to pass through can be provided in the second flange plate 250. In this way, the protective cover 200 can be easily connected to the fork 10, especially in the direction of the long axis of the first long hole 251.

[0042] In this regard, preferably, in particular with reference to Figure 1 and Figures 3A-3C When the second flange plate 250 extends toward between the third leg plate 220 and the fourth leg plate 230 of the protective cover 200, the first connecting plate 110 of the support plate 100 and the second connecting plate 210 of the protective cover 200 may be respectively provided with a second supporting plate corresponding hole 113 and a second protective cover corresponding hole 213 aligned with the first long hole 251. The areas of the second supporting plate corresponding hole 113 and the second protective cover corresponding hole 213 may be larger than the areas of the first long hole 251. This makes it easier to tighten the bolts connecting the protective cover 200 and the fork 10 from the outside.

[0043] In the illustrated embodiment, the protective cover 200 can be adjustably connected to the side 11 of the fork 10 by two bolts and corresponding two first long holes 251 and corresponding two second support plate corresponding holes 113 and corresponding two second protective cover corresponding holes 213. However, it is conceivable that the protective cover 200 can be adjustably connected to the side 11 of the fork 10 at an appropriate position by any number of bolts and corresponding number of first long holes 251 and corresponding number of second support plate corresponding holes 113 and corresponding number of second protective cover corresponding holes 213 as required.

[0044] Furthermore, in this context, it is preferred that the long axis of the first long hole 251 can extend parallel to the side surface 11 of the fork 10 and thus can be extended in particular in the vertical direction (ie in the Figure 1The edge detection device 20 extends in a direction perpendicular to the paper surface in the drawings. Thus, the relative position of the protective cover 200 and the fork 10 can be adjusted in the vertical direction, and thus the relative position of the edge detection device 20 relative to the fork 10 can be adjusted.

[0045] According to some embodiments of the present disclosure, the first leg plate 120 and the second leg plate 130 of the support plate 100 can be connected to the third leg plate 220 and the fourth leg plate 230 of the protective cover 200 by bolts and nuts. To this end, the first leg plate 120 and the second leg plate 130 of the support plate 100 can be provided with a second hole 121 for the bolt to pass through, and the third leg plate 220 and the fourth leg plate 230 of the protective cover 200 can be provided with a second long hole 221 for the bolt to pass through. In this way, the adjustable connection between the support plate 100 and the protective cover 200 can be simply achieved.

[0046] In the illustrated embodiment, the first leg plate 120 of the support plate 100 and the third leg plate 220 of the protective cover 200 may be connected to each other by two bolts and nuts and corresponding two second holes 121 and two second long holes 221, and the second leg plate 130 of the support plate 100 and the fourth leg plate 230 of the protective cover 200 may be connected to each other by two bolts and nuts and corresponding two second holes 121 and two second long holes 221. However, it is conceivable that the first leg plate 120 of the support plate 100 and the third leg plate 220 of the protective cover 200 may be connected to each other at appropriate positions by any number of bolts and nuts and corresponding numbers of second holes 121 and second long holes 221 as required, and the second leg plate 130 of the support plate 100 and the fourth leg plate 230 of the protective cover 200 may be connected to each other at appropriate positions by any number of bolts and nuts and corresponding numbers of second holes 121 and second long holes 221 as required.

[0047] In this regard, preferably, the long axis of the second long hole 221 can extend perpendicularly to the side surface 11 of the fork 10 and can thus extend in particular in the horizontal direction. As a result, the relative position of the support plate 100 and the protective cover 200 and thus the relative position of the edge detection device 20 relative to the fork 10 can be adjusted in the horizontal direction.

[0048] When the edge detection device 20 is assembled on the fork 10 of the AGV forklift using the assembly assembly 30 according to the present disclosure, the fork 10 of the AGV forklift can be lowered to a suitable position first. Then, the edge detection device 20 is fixedly fixed on the support plate 100 of the assembly assembly 30 by bolts. After that, the support plate 100 of the assembly assembly 30 is non-fixedly connected to the protective cover 200 of the assembly assembly 30 by bolts and nuts. Then, the protective cover 200 of the assembly assembly 30 is fixedly fixed to the side 11 of the fork 10 of the AGV forklift by bolts. After that, by raising and lowering the fork 10, the position of the support plate 100 of the assembly assembly 30 relative to the protective cover 200 of the assembly assembly 30 is adjusted so that the light beam of the edge detection device 20 always remains vertically irradiated during the raising and lowering process of the fork 10. Then, the support plate 100 and the protective cover 200 are fixedly fixed. Thus, the installation of the edge detection device 20 can be completed. During the operation of the AGV forklift, the assembly component 30 can protect the edge detection device 20 to prevent it from being displaced. If the edge detection device needs to be disassembled, only the protective cover 200 and the support plate 100 need to be disassembled to disassemble the edge detection device 20. Therefore, disassembly is also relatively convenient.

[0049] Therefore, the assembly assembly according to the present disclosure can make the edge detection device mounted on the fork of the AGV forklift less affected by the surrounding environment (for example, positional displacement or displacement due to being hit by external cigarette boxes), thereby reducing the possibility of positional displacement of the edge detection device and thus reducing the possibility of the AGV forklift placing the cigarette boxes in an irregular or crooked manner. This can reduce or avoid the risk of, for example, the cigarette box falling, and can also reduce the number and time of correcting the placement of the cigarette box.

[0050] Although the present disclosure has been disclosed as above in the form of a preferred embodiment, it is not intended to limit the present disclosure. Any technical personnel in this field can make possible changes and modifications to the technical solution of the present disclosure by using the methods and technical contents disclosed above without departing from the spirit and scope of the present disclosure. Therefore, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present disclosure without departing from the content of the technical solution of the present disclosure shall fall within the protection scope of the technical solution of the present disclosure.

[0051] The features disclosed in this document may be implemented not only individually but also in any combination. It should also be noted that the various drawings of the present disclosure are schematic and may not be shown to scale. In various embodiments, the number, configuration and / or arrangement of components are also not limited to the examples shown.
