[0043] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0044] See also Figure 1 and Figure 2, are schematic diagrams of the overall structure of the luggage lifting device provided by the present invention in the first stereoscopic perspective and the second stereoscopic perspective. The luggage lifting device 100 includes a housing 101 and a conveying inlet 102 and a conveying outlet 103 of a luggage tray 200 opened on the housing 101, and is mainly used in the luggage tray Huikuang system.

[0045] The conveying entrance 102 is located at a lower position of the whole machine, while the conveying exit 103 is located at a higher position of the whole machine. After the luggage tray 200 enters the luggage lifting device 100 through the conveying entrance 102, the input assembly, the lifting assembly and the output assembly can be used to complete the input action, the lifting action and the output action of the luggage tray 200.

[0046] It can be understood that a frame (not shown) is provided inside the housing 101, and the input assembly, the lifting assembly and the output assembly are all arranged on the frame.

[0047] See also Figure 3 and Figure 4 , respectively, are schematic diagrams of partially disassembled structures of the luggage lifting device provided by the present invention in the first operating state at the first stereoscopic viewing angle and the second stereoscopic viewing angle. Figure 1 , Figure 2 The input assembly 104 includes a side plate extending toward the rear side of the luggage lifting device 100 and a rolling carrier 1041 arranged between the side plates. Here, the rolling carrier 1041 may specifically include a plurality of electric rollers, which are arranged side by side. The electric rollers arranged side by side can constitute an input path for conveying the luggage tray 200 from the conveying entrance 102 to the preset area direction, so as to support the lifting assembly 105 to lift the luggage tray 200 located in the preset area position. The preset area can be set at the end of the input path.

[0048] The lifting assembly 105 includes a lifting fork arm 1051 disposed at the rear of the luggage lifting device 100 and a lifting driving member 1052 for driving the lifting fork arm 1051 to rise and fall in the height direction, and the lifting driving member 1052 can be specifically a linear driver. The lifting fork arm 1051 includes two support rods, a connecting rod connecting the two support rods, and a movable block for connecting the connecting rod and the lifting driving member 1052, and the movable block is movably disposed on the lifting driving member 1052. When the luggage tray 200 is transported to the preset area position, the two support rods of the lifting fork arm 1051 are respectively located below the two opposite short side edges of the luggage tray 200, and the connecting rod can be in contact with, or not in contact with, the outer side wall of the luggage tray 200. It can be understood that the two support rods are arranged at the same height.

[0049] The output assembly 106 includes a telescopic drive member and a support member, wherein the telescopic drive member can adopt a compression chain transmission device 1061, and the support member includes a first support plate 1062 and a first driver 1063 for driving the first support plate 1062 to move, a second support plate 1064 and a second driver 1065 for driving the second support plate 1064 to move, and the distance between the first support plate 1062 and the second support plate 1064 is adjusted by the corresponding driver 1063, and the plate surfaces of the first support plate 1062 and the second support plate 1064 are both vertically arranged, and the upper plate edges of the two are arranged at the same height for the luggage tray 200 to slide.

[0050] The compression chain transmission device 1061 is arranged between the first support plate 1062 and the second support plate 1064, and the compression chain transmission device 1061 includes a telescopic hook 1066. Specifically, the compression chain transmission device 1061 can adopt a Tsubaki Zip Chain transmission device. The first driver 1063 and the second driver 1065 can both adopt linear drivers, and the two can be respectively arranged on the chain storage cylinder of the compression chain transmission device 1061.

[0051] Here, the support member is used to: when the lifting fork arm 1051 lifts the luggage tray 200 to the first preset height, move to the bottom of the luggage tray 200, that is, under the driving action of the first driver 1063 and the second driver 1065, by shortening the distance between the first support plate 1062 and the second support plate 1064, the luggage tray 200 can be placed on the upper plate edges of the two; when the lifting fork arm 1051 lifts the luggage tray 200 to the second preset height, the luggage tray 200 contacts the upper plate edges of the two and can be slidable. Here, the first preset height is greater than the second preset height. Here, the first preset height and the second preset height are both measured by the height of the position where the highest part of the luggage tray 200 is located.

[0052] The telescopic driving member is used to move to the bottom of the luggage tray 200 when the lifting fork arm 1051 lifts the luggage tray 200 to the first preset height, that is, at this time, the telescopic hook 1066 extends to the bottom of the luggage tray. When the lifting fork arm 1051 lifts the luggage tray 200 to the second preset height, the telescopic hook 1066 hooks and pulls the luggage tray 200 to slide along the upper plate edge of the first support plate 1062 and the second support plate 1064 to hook the luggage tray 200 away from the lifting fork arm 1051.

[0053] It is understandable that the first preset height can also be equal to the second preset height. In this case, the difference between the first preset height and the upper edge height of the first support plate 1062 and the second support plate 1064 is equal to the difference between the highest part and the lowest part of the luggage tray 200.

[0054] Figure 3 and Figure 4 The action shown is: the luggage tray 200 is transported to the preset area by the rolling carrier 1041 of the input assembly 104. At the preset area position, the lifting fork arms 1051 of the lifting assembly 105 can be inserted into both sides of the luggage tray 200, and the height of the lifting fork arms 1051 is the initial height. When the lifting driving member 1052 drives the lifting fork arms 1051 to lift, the lifting fork arms 1051 abut against the edge of the luggage tray 200, forming a fork holding the luggage tray 200.

[0055] See also Figure 5 and Figure 6 , are schematic diagrams of partially disassembled structures of the luggage lifting device provided by the present invention in a second action state at a first stereoscopic viewing angle and a second stereoscopic viewing angle, respectively. Figure 5 and Figure 6 The action shown is: the luggage tray 200 is forked and fixed by the lifting fork arm 1051, and the lifting fork arm 1051 is lifted up under the drive of the lifting drive member 1052.

[0056] It can be understood that in the first action state and the second action state, the distance between the first support plate 1062 and the second support plate 1064 is sufficient for the luggage tray 200 driven by the lifting fork arm 1051 to pass through.

[0057] See also Figure 7 and Figure 8 , are schematic diagrams of partially disassembled structures of the luggage lifting device provided by the present invention in the third action state at the first stereoscopic viewing angle and the second stereoscopic viewing angle, respectively. Figure 7 and Figure 8 The action shown is: the luggage tray 200 is lifted by the lifting assembly 105 to a first preset height position, where the first preset height position is the height of the luggage tray 200 held by the lifting fork arm 1051 when the lifting fork arm 1051 is at the maximum stroke position.

[0058] See also Fig. 9 and Fig.10 , are schematic diagrams of partially disassembled structures of the luggage lifting device provided by the present invention in the fourth action state at the first stereoscopic viewing angle and the second stereoscopic viewing angle, respectively. Fig. 9 and Fig.10The action shown is: after the luggage tray 200 is lifted to the first preset height position by the lifting assembly 105, the compression chain transmission device 1061 drives the telescopic hook 1066 to extend and extend to the position of the luggage tray 200 close to the lifting drive member 1052, and the projections of the luggage tray 200 and the telescopic rod of the telescopic hook 1066 on the horizontal plane coincide with each other, and the hook action surface of the telescopic hook 1066 is closer to the lifting path or the extension line of the lifting path of the lifting drive member 1052 than the luggage tray 200, thereby supporting: when the luggage tray 200 is lowered by the lifting drive member 1052 to the point where its bottom surface abuts against the upper plate edges of the first support plate 1062 and the second support plate 1064, the luggage tray 200 is on the retraction path of the telescopic hook 1066; when the telescopic hook 1066 retracts, it can move the luggage tray 200 out of the lifting fork arm 1051.

[0059] It can be understood that after the luggage tray 200 is lifted to the first preset height position by the lifting assembly 105, the first driver 1063 drives the first support plate 1062 and the second driver 1065 drives the second support plate 1064, and the distance between the first support plate 1062 and the second support plate 1064 is shortened, so that the projections of the first support plates 1062 and the second support plates 1064 on the horizontal plane coincide with the projections of the bottom surface of the luggage tray 200 on the horizontal plane, thereby supporting the luggage tray 200 to be placed on the upper edges of the first support plates 1062 and the second support plates 1064.

[0060] See also Fig.11 and Fig.12 , are schematic diagrams of partially disassembled structures of the luggage lifting device provided by the present invention in the fifth action state at the first stereoscopic viewing angle and the second stereoscopic viewing angle, respectively. Fig.11 and Fig.12 The action shown is: the luggage tray 200 is driven by the lifting driving member 1052 to descend until its bottom surface abuts against the upper edges of the first support plate 1062 and the second support plate 1064, and the lifting driving member 1052 continues to descend and separates the lifting fork arm 1051 from the luggage tray 200. When the lifting fork arm 1051 separates from the luggage tray 200, the height of the luggage tray 200 is the second preset height, and the second preset height is less than the first preset height.

[0061] See also Fig.13 and Fig.14 , are schematic diagrams of partially disassembled structures of the luggage lifting device provided by the present invention in the sixth action state at the first stereoscopic viewing angle and the second stereoscopic viewing angle, respectively. Fig.13 and Fig.14The action shown is: after the luggage 300 is placed in the luggage tray 200 located at the top side, the telescopic hook 1066 contracts to drive the luggage tray 200 to move along the upper plate edges of the first support plate 1062 and the second support plate 1064 to output the luggage tray 200. At the same time, the lifting drive member 1052 drives the lifting fork arm 1051 to descend to the initial position, so as to prepare for lifting the luggage tray 200 input by the conveying assembly 104 again.

[0062] Combination Figures 1 to 14 The luggage tray 200 provided by the present invention includes a bracket 201 for placing luggage and a frame 202 arranged at the opening of the bracket 201. The bracket 201 at least includes two first side walls for forking the lifting fork arm 1051 and a second side wall for hooking the telescopic hook 1066, and the second side wall is located between the two first side walls. Here, the bracket 201 is a square groove, and the frame 202 is a square frame matching the opening of the square bracket. It can be understood that the square groove can be a square groove or a rectangular groove. Here, a luggage tray 200 with a long groove is selected, including two short sides and two long sides.

[0063] After the luggage tray 200 enters the input assembly 104 through the conveying entrance 102, the luggage tray 200 is moved away from the conveying entrance 102 by the rolling carriers 1041 arranged side by side until it reaches the preset area. When the luggage tray 200 is conveyed to the preset area, the two rods of the lifting fork arm 1051 are located at the lower edge of the frame of the luggage tray 200. Here, the path of the luggage tray 200 moving from the conveying entrance 102 to the preset area is the input path, wherein the conveying entrance 102 can be counted as the beginning of the input path, and the preset area can be counted as the end of the input path.

[0064] The lifting drive 1052 drives the lifting fork arm 1051 to lift, so that the two rods of the lifting fork arm 1051 are in contact with the luggage tray 200, and under the further drive of the lifting drive 1052, the luggage tray 200 leaves the preset area until the lifting arm 1051 is lifted to the first preset height position.

[0065] In the initial state of the output assembly 106, the distance between the first support plate 1062 and the second support plate 1064 is greater than the long side edge of the luggage tray 200, that is, the heights of the first support plate 1062 and the second support plate 1064 remain unchanged. The distance between the first support plate 1062 and the second support plate 1064 is changed so that the luggage tray 200 can pass through or be placed on the upper edges of the two support plates.

[0066] After the lifting fork arm 1051 lifts the luggage tray 200 to the first preset height, the first support plate 1062 and the second support plate 1064 move closer to each other so that the distance between them is smaller than the long side of the bottom surface of the luggage tray 200. At the same time, the compression chain transmission device 1061 drives the telescopic hook 1066 to extend, so that the hook action surface of the telescopic hook 1066 is closer to the lifting path of the lifting drive member 1052 or the extension line of the lifting path than the luggage tray 200.

[0067] The lifting driving member 1052 drives the lifting fork arm 1051 to descend, and when the lifting fork arm 1051 drives the luggage tray 200 to descend to the second preset height, the lifting fork arm 1051 separates from the luggage tray 200. The path of the luggage tray 200 moving from the preset area position to the position of the lifting fork arm 1051 at the second preset height is the lifting path, the preset area position can be counted as the beginning of the lifting path, and the position of the luggage tray 200 at the second preset height of the lifting fork arm 1051 can be counted as the end of the lifting path.

[0068] After that, the telescopic hook 1066 retracts, so that the telescopic hook 1066 acts on the luggage tray 200 and moves it toward the delivery outlet 103. At the same time, the lifting drive 1052 drives the lifting fork arm 1051 to continue to descend to the initial height. The path from the position of the luggage tray 200 when the lifting fork arm 1051 is at the second preset height to the position of the delivery outlet 103 is the delivery path, and the position of the luggage tray 200 when the lifting fork arm 1051 is at the second preset height can be counted as the starting point of the delivery path, and the position of the delivery outlet 103 can be counted as the end of the delivery path.

[0069] In summary, the luggage lifting device of the present invention includes an input assembly, a lifting assembly and an output assembly, which can recover the luggage tray and transport it to the security entrance, and lift it to the luggage table position. Passengers can directly put their luggage items on the tray, without the need for security personnel to recover and carry the luggage tray, and passengers do not need to bend down to take it themselves.

[0070] The lifting drive adopts a linear drive. The lifting fork arm installed on the linear drive lifts the luggage tray, which is then supported by the support plates on both sides. Finally, the compression chain transmission device (ZIP CHAIN) is used as a telescopic drive to hook and pull the luggage tray for transfer, which is more stable. The whole machine is relatively compact in design, occupies a small space, has a precise lifting position, low noise, and can be used in parallel to improve security inspection efficiency.

[0071] In the present invention, the luggage lifting device 100 can realize the lifting control of the luggage lifting device 100 by the following method:

[0072] S101: After detecting that the luggage tray enters through the conveying entrance, the input assembly is controlled to convey the luggage tray along the input path to the preset area. Specifically, the luggage tray can be sensed by a first sensor disposed at the conveying entrance, and a first sensing signal is output when the luggage tray exists at the conveying entrance. If the first sensor senses the luggage tray, the controller controls the electric roller of the input assembly to rotate according to the first sensing signal to convey the luggage tray to the preset area.

[0073] S102: If it is detected that there is a luggage tray in the preset area, the lifting assembly is controlled to lift the luggage tray to the first preset height along the lifting path. Specifically, a second sensor arranged near the preset area can be used to sense whether there is a luggage tray in the preset area, and when there is a luggage tray in the preset area, a second sensing signal is output. If the second sensor senses the luggage tray, the controller controls the lifting assembly to fork the luggage tray with its lifting fork arm and lift it under the drive of the lifting drive member according to the second sensing signal. In addition, the controller can also control the movement of the support member according to the second sensing signal to provide sufficient space for the luggage tray to be lifted. More specifically, sufficient space for the luggage tray can be provided by increasing the distance between the first support plate and the second support plate of the support member.

[0074] S103: If it is detected that there is a luggage tray at the first preset height, the support member of the output assembly is controlled to move to the bottom of the luggage tray and the telescopic hook is extended to the bottom of the luggage tray. Specifically, a third sensor arranged on the frame can be used to sense whether there is a luggage tray at the first preset height, and when there is a luggage tray, a third sensing signal is output. If the third sensor senses the luggage tray, the controller controls the support member to move to the bottom of the luggage tray and the telescopic hook is extended to the bottom of the luggage tray according to the third sensing signal. More specifically, by shortening the distance between the first support plate and the second support plate of the support member, the luggage tray can be placed on the upper plate edge of the two.

[0075] S104: If it is detected that the support member moves to below the luggage tray, the lifting drive member is controlled to bring the luggage tray to a second preset height position. Specifically, the fourth sensor can be used to sense that the support member is below the luggage tray, and if so, a fourth sensing signal is generated. The controller can control the lifting drive member to drive the lifting fork arm to move downward according to the fourth sensing signal, thereby placing the luggage tray on the support member.

[0076] S105: If the luggage tray is at the second preset height position, the telescopic driving member is controlled to use the telescopic hook to hook the luggage tray and slide it along the support plate along the output path to the delivery outlet. Specifically, the fifth sensor can be used to sense whether there is a luggage tray on the support member, and if so, a fifth sensing signal is generated. The controller can control the telescopic driving member to drive the telescopic hook according to the fifth sensing signal, so that the telescopic hook hooks the luggage tray and slides it along the support member and moves it toward the delivery outlet.

[0077] It is understandable that a start switch may be provided, and after the passenger places the luggage in the luggage tray, the passenger may turn on the start switch to execute the steps in S105.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
