For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0089] 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.

[0090] refer to Figures 1 to 8 The present application provides a frame disassembly device 1, comprising: a main body 10, a frame inlet 21, a frame outlet 22, a first transmission part 30, a first limit part 40 and a second limit part 41. The main body 10 has a receiving part 20, which is located on the support part 1a of the main body 10, and a roller 1b is provided at the bottom of the support part 1a. In the present application, the receiving part 20 is arranged along the first direction ( Figures 1 to 7 The first direction is the depth direction of the main body 10, that is, the height direction of the main body 10.

[0091] The frame inlet 21 is located at the top of the main body 10, and the frame inlet 21 is connected to the receiving portion 20. The frame outlet 22 is located at the side of the main body 10, and the frame outlet 22 is connected to the receiving portion 20. In the present application, the receiving portion 20 is in a square shape. The first transmission portion 30 is located at the bottom of the receiving portion 20, and the first transmission portion 30 is used to carry the empty frame 2 and transmit the empty frame 2 along the second direction ( Figures 1 to 6The empty frame 2 is output from the frame outlet 22 (as shown in the Y direction in the middle), and the second direction is perpendicular to the first direction. Equivalently, the empty frame 2 can be collected from the frame inlet 21 into the receiving portion 20 of the frame dismantling device 1, and then the empty frame 2 is output from the frame outlet 22 by the first transmission unit 30, for example, to the security inspection machine for passengers to take.

[0092] In addition, the first limit portion 40 and the second limit portion 41 are installed on the main body 10, and along the first direction, the second limit portion 41 is located below the first limit portion. In the present application, the first limit portion 40 can be switched between the first position and the second position, and the second limit portion 41 can be switched between the third position and the fourth position.

[0093] Among them, when the first limiting portion 40 is in the first position, the first limiting portion 40 can be against the empty frame 2 inserted from the frame entry port 21 to limit the empty frame 2 from moving downward along the first direction. The empty frame 2 against the first limiting portion 40 can stack more than one empty frame 2 inserted from the frame entry port 21.

[0094] That is, when the first limiting portion 40 is at the first position, after the empty frame 2 is transferred from the frame entry 21 to the receiving portion 20 (for example, through the second transfer portion 50 described later (refer to Fig.14 ) to the frame inlet 21), the empty frame 2 falls into the accommodating portion 20 along the first direction and can abut against the first limiting portion 40. The first limiting portion 40 supports the empty frame 2, and the empty frame 2 will not continue to move downward along the first direction (toward the direction of the first transporting portion 30). When the empty frame 2 is continuously transported from the frame inlet 21 to the accommodating portion 20, subsequent empty frames 2 can be stacked in the empty frame 2 abutting against the first limiting portion 40.

[0095] For example, Figure 4 and Figure 7 As shown, the first limiting portion 40 abuts against an empty frame 2, and three empty frames 2 are stacked in the first direction in the empty frame 2. Equivalently, the first limiting portion 40 supports a total of four empty frames 2, and the first limiting portion 40 abuts against the bottom empty frame 2 among the four empty frames 2. Therefore, when the first limiting portion 40 is in the first position, the first limiting portion 40 can play the role of collecting and storing the empty frames 2.

[0096] When the first limiting portion 40 is at the second position, the first limiting portion 40 can be separated from the empty frame 2 inserted from the frame entry opening 21, so that the empty frame 2 moves downward along the first direction.

[0097] That is, when the first limiting portion 40 switches from the first position to the second position, the first limiting portion 40 can be separated from an empty frame 2 abutting against it, so that the empty frame 2 abutting against the first limiting portion 40 and all the empty frames 2 stacked in the empty frame 2 will move downward along the first direction. It is also equivalent to that the first limiting portion 40 will not continue to support the empty frame 2. After the empty frame 2 abutting against the first limiting portion 40 is separated from the first limiting portion 40, it will move downward along the first direction and can abut against the second limiting portion 41 in the third position, as described below.

[0098] When the second limiting portion 41 is at the third position, the second limiting portion 41 can abut against the empty frame 2 inserted from the frame entry opening 21 to limit the empty frame 2 from moving downward along the first direction.

[0099] That is, when the second limiting portion 41 is in the third position, after the empty frame 2 is transferred from the frame entry 21 to the receiving portion 20, the empty frame 2 falls into the receiving portion 20 along the first direction and abuts against the second limiting portion 41. When the second limiting portion 41 is in the third position, the first limiting portion 40 can be controlled from the first position to the second position. In this position state, there are at least two sources of the empty frame 2 abutting against the second limiting portion 41:

[0100] One possible implementation is that the frame removing device 1 is in an initial state, and the first limiting portion 40 does not support any empty frame 2, that is, when the first limiting portion 40 is switched from the first position to the second position, no empty frame 2 separated from the first limiting portion 40 will fall downward along the first direction and abut against the second limiting portion 41; the first limiting portion 40 is in the second position and will not block the empty frame 2 from moving downward along the first direction, so that an empty frame 2 or multiple stacked empty frames 2 can be manually or automatically placed into the accommodating portion 20 from the frame entry 21, and one or more stacked empty frames 2 move downward along the first direction until they are supported by the second limiting portion 41, and the bottom empty frame 2 abuts against the second limiting portion 41.

[0101] In this embodiment, when no empty frame 2 is collected in the receiving portion 20, the first limiting portion 40 is controlled to be in the second position, and the second limiting portion 41 is controlled to be in the third position. The staff manually puts an empty frame 2 into the receiving portion 20 to abut against the second limiting portion 41, that is, the second limiting portion 41 supports an empty frame 2; and then manually or automatically transfers the empty frame 2 into the receiving portion 20, which may be a plurality of stacked empty frames 2 transferred together, or one by one. Since an empty frame 2 is placed on the second limiting portion 41 in advance, the subsequently transferred empty frame 2 can conveniently fall into the pre-placed empty frame 2.

[0102] Another possible embodiment is, as mentioned above, the first limiting portion 40 supports one or more empty frames 2 when in the first position, and when the first limiting portion 40 is controlled to switch from the first position to the second position, all the empty frames 2 that are against the first limiting portion 40 are separated from the first limiting portion 40, and then move downward along the first direction until they are supported by the second limiting portion 41, and the empty frame 2 at the bottom is against the second limiting portion 41.

[0103] Regardless of whether the empty frame 2 that abuts the second limiting portion 41 is an empty frame 2 separated from the first limiting portion 40 or an empty frame 2 that falls directly from the frame entry 21, when the second limiting portion 41 abuts against an empty frame 2, the remaining empty frames 2 stacked in the empty frame 2 are supported by the first limiting portion 40. That is, the second limiting portion 41 is controlled to remain in the third position, and the first limiting portion 40 is controlled to switch from the second position to the first position. At this time, refer to Figure 6 and Figure 7 As shown, the second limit portion 41 abuts against an empty frame 2, and the first limit portion 40 abuts against an empty frame 2 above the empty frame 2. Figure 7 As shown, the first limiting portion 40 supports four empty frames 2, and the second limiting portion 41 supports one empty frame 2 to abut against each other.

[0104] This is equivalent to that, of all the empty frames 2 placed from the frame entry 21 into the accommodating portion 20, the bottommost empty frame 2 is supported by the second limiting portion 41, and the remaining empty frames 2 are supported by the first limiting portion 40. At this time, the second limiting portion 41 can be controlled to switch from the third position to the fourth position to perform frame removal, as described below.

[0105] Exemplarily, when the first limit portion 40 supports at least one empty frame 2 and the second limit portion 41 supports one empty frame 2, the frame removal operation can be performed. At this time, the second limit portion 41 is controlled to switch from the third position to the fourth position, the first limit portion 40 is located in the first position, and the second limit portion 41 can be separated from the empty frame 2 inserted from the frame entry 21, so that one empty frame 2 moves downward along the first direction until it is carried by the first transmission portion 30.

[0106] That is, when the frame is removed, the first limit portion 40 is located at the first position, the second limit portion 41 is located at the fourth position, and an empty frame 2 supported by the second limit portion 41 moves downward along the first direction until it is carried by the first transmission portion 30, and the first transmission portion 30 moves downward along the second direction ( Figures 1 to 6 An empty frame 2 separated from the second limiting portion 41 is output from the frame outlet 22 (as shown in the Y direction).

[0107] The first limiting portion 40 is continuously controlled to switch between the first position and the second position, and the second limiting portion 41 is controlled to switch between the third position and the fourth position. When the frame dismantling condition is met (the first limiting portion 40 supports at least one empty frame 2, and the second limiting portion 41 supports one empty frame 2), the empty frames 2 collected from the frame entry 21 into the accommodating portion 20 of the frame dismantling device 1 are dismantled one by one, and then the empty frames 2 are output from the frame exit 22 by the first transmission portion 30, and the empty frames 2 are transmitted to passengers one by one for the passengers to take and place their luggage for security inspection.

[0108] Therefore, in the present application, in the process of de-framing using the de-framing device 1, the accommodating portion 20 collects and stores the empty frames 2 after the passengers have completed the security check, and the first limiting portion 40 supports at least one empty frame 2. When the second limiting portion 41 also supports an empty frame 2, the second limiting portion 41 is controlled to be located at the fourth position to perform the de-framing operation, and the stacked empty frames 2 are de-framed. What is transmitted to the passengers is the separated empty frames 2 one by one, rather than the stacked empty frames 2, which is convenient for passengers to use the empty frames 2 to place their luggage for security checks, thereby improving the security check efficiency. In addition, the labor intensity of the security check staff is also reduced, and the empty frame 2 collection and de-framing operations are completed by the de-framing device 1, thereby improving the work efficiency.

[0109] In addition, the first limit part 40 is located at the first position, and the empty frames 2 can be continuously collected; and the second limit part 41 switches positions to complete the frame removal operation, so that the frame removal device 1 of the present application has both the empty frame storage function and the frame removal function. There is no need to collect the empty frames 2 one by one and then remove the frames one by one; the frame removal process does not affect the empty frame collection process, and the frame removal process and the empty frame collection process can be performed simultaneously, which improves the efficiency of empty frame collection and frame removal.

[0110] In some possible embodiments, when the second limiting portion 41 is in the third position, the second limiting portion 41 can abut against the empty frame 2 separated from the first limiting portion 40; when the second limiting portion 41 is in the fourth position, the second limiting portion 41 can separate from an empty frame 2 separated from the first limiting portion 40. That is, when the first limiting portion 40 is in the first position, the bottom empty frame 2 supported by the first limiting portion 40 is separated from the first limiting portion 40 and moves downward along the first direction to abut against the second limiting portion 41 in the third position. When the second limiting portion 41 is switched from the third position to the fourth position, the bottom empty frame 2 is separated from the second limiting portion 41 and moves downward along the first direction to be carried by the first transmission portion 30, and the first transmission portion 30 transmits the bottom empty frame 2 out of the frame outlet 22. Repeat the above operation, and the bottommost empty frames 2 supported by the first limiting portion 40 fall into the second limiting portion 41 one by one, completing the frame removal operation of all the empty frames 2 supported by the first limiting portion 40 .

[0111] In some possible embodiments, the second limiting portion 41 is in the third position, the second limiting portion 41 can be offset against an empty frame 2, and another empty frame 2 can be stacked in the empty frame 2; the second limiting portion 41 is in the fourth position, the second limiting portion 41 can be separated from an empty frame 2; the first limiting portion 40 is in the first position, the first limiting portion 40 can be offset against another empty frame 2, and more than one empty frame 2 inserted from the frame entry 21 can be stacked in the other empty frame 2; the first limiting portion 40 is in the second position, the first limiting portion 40 can be separated from the other empty frame 2, so that the other empty frame 2 and the empty frames 2 stacked in the other empty frame 2 move downward along the first direction, and the other empty frame 2 can be offset against the second limiting portion 41.

[0112] That is, when the second limiting part 41 supports two empty frames 2 (one empty frame and another empty frame), the first limiting part 40 is controlled to be in the first position and abut against the other empty frame 2, and then the other empty frame 2 supported by the first limiting part 40 can collect more than one empty frame 2 from the frame inlet 21, and the second limiting part 41 can be separated from one empty frame 2 to complete the frame removal. Then the first limiting part 40 is controlled to switch to the second position to separate from the other empty frame 2 abutting against it, so that the other empty frame 2 and the empty frames 2 stacked in the other empty frame 2 move downward along the first direction, and the other empty frame 2 abuts against the second limiting part 41 again. Then repeat the above operation, control the first limiting part 40 to switch from the second position to the first position, and abut against the empty frame 2 above the other empty frame 2; the second limiting part 41 is switched to the fourth position to separate from the other empty frame 2. The above operation is continuously performed to complete the frame removal process.

[0113] refer to Figure 7 Combined with Figure 4 and Figure 8 As shown, in some possible implementations, the first limiting portion 40 is in the first position, and the first limiting portion 40 abuts against an empty frame 2; the second limiting portion 41 is in the third position, and the second limiting portion 41 abuts against an empty frame 2; an empty frame 2 abutting against the first limiting portion 40 is located in an empty frame 2 abutting against the second limiting portion 41. Before the first limiting portion 40 is switched from the second position to the first position, more than one empty frame 2 can be stacked in an empty frame 2 abutting against the second limiting portion 41. When the first limiting portion 40 is switched to the first position, it directly abuts against the empty frame 2 located in the empty frame 2 abutting against the second limiting portion 41, so that the empty frame 2 below the empty frame 2 abutting against the first limiting portion 40 can be separated from the second limiting portion 41 to complete the frame removal operation.

[0114] Continue to refer Figures 1 to 7 , and combined with Figures 8 to 13 As shown, along the third direction ( Figure 2 , Figure 3 , Figure 7 , Fig.12 The receiving portion 20 includes a first portion 211 and a second portion 212 that are arranged opposite to each other, and the first portion 211 and the second portion 212 extend along the first direction respectively. The first portion 211 and the second portion 212 of the receiving portion 20 are equivalent to two oppositely arranged side walls of the receiving portion 20. In the present application, the first portion 211 of the receiving portion 20 is provided with a first through hole 213, and the second portion 212 of the receiving portion 20 is provided with a second through hole 214, and the first direction, the second direction and the third direction are perpendicular to each other.

[0115] In a possible embodiment, the first limiting portion 40 includes: a first electric cylinder 401, which is installed on the side of the main body 10 opposite to the first part 211, and the first electric cylinder 401 has a first telescopic member 403, and the first telescopic member 403 is provided with a first clamping member 404, and the first clamping member 404 is located at the first through hole 213; a second electric cylinder 411, which is installed on the side of the main body 10 opposite to the second part 212, and is spaced apart from the first electric cylinder 401 along a third direction, and the second electric cylinder 411 has a second telescopic member, and the second telescopic member is provided with a second clamping member 407, and the second clamping member 407 is located at the second through hole 214.

[0116] Fig. 9 The structure of the first electric cylinder 401, the first telescopic member 403 and the first clamping member 404 is shown. The structure of the second electric cylinder 411 is the same as that of the first electric cylinder 401, the structure of the second telescopic member is the same as that of the first telescopic member 403, and the structure of the second clamping member 407 is the same as that of the first clamping member 404. The first electric cylinder 401 works to drive the first telescopic member 403 to extend and retract, thereby driving the first clamping member 404 to extend and retract at the first through hole 213. Correspondingly, the second electric cylinder 411 works to drive the second telescopic member to extend and retract, thereby driving the second clamping member 407 to extend and retract at the second through hole 214.

[0117] In the present application, the second limiting part 41 includes: a third electric cylinder 402, which is installed on the side of the main body 10 opposite to the first part 211, and the third electric cylinder 402 has a third telescopic member 405, and the third telescopic member 405 is provided with a third clamping member 406, and the third clamping member 406 is located at the first through hole 213; a fourth electric cylinder 412, which is installed on the side of the main body 10 opposite to the second part 212, and is spaced from the third electric cylinder 402 along the third direction, and the fourth electric cylinder 412 has a fourth telescopic member, and the fourth telescopic member is provided with a fourth clamping member 408, and the fourth clamping member 408 is located at the second through hole 214. Figure 4 As shown, the first clamping member 404 and the third clamping member 406 are both located at the first through hole 213. Figure 8As shown, the second clamping member 407 and the fourth clamping member 408 are both located at the second through hole 214 .

[0118] Fig. 9 The structure of the third electric cylinder 402, the third telescopic member 405 and the third clamping member 406 is shown. The structure of the fourth electric cylinder 412 is the same as that of the third electric cylinder 402, the structure of the fourth telescopic member is the same as that of the third telescopic member 405, and the structure of the fourth clamping member 408 is the same as that of the third clamping member 406. The third electric cylinder 402 works to drive the third telescopic member 405 to extend and retract, thereby driving the third clamping member 406 to extend and retract at the first through hole 213. Correspondingly, the fourth electric cylinder 412 works to drive the fourth telescopic member to extend and retract, thereby driving the fourth clamping member 408 to extend and retract at the second through hole 214.

[0119] Exemplarily, when the first position-limiting portion 40 is in the first position, the first clamping member 404 extends out of the first through hole 213, and the second clamping member 407 extends out of the second through hole 214. When the first position-limiting portion 40 is in the second position, the first clamping member 404 is in a retracted state, and the second clamping member 407 is in a retracted state. Exemplarily, when the first position-limiting portion 40 is in the second position, the first clamping member 404 is retracted to the outside of the first portion 211, and the second clamping member 407 is retracted to the outside of the second portion 212.

[0120] Exemplarily, when the second position-limiting portion 41 is in the first position, the third clamping member 406 extends out of the first through hole 213, and the fourth clamping member 408 extends out of the second through hole 214. When the second position-limiting portion 41 is in the second position, the third clamping member 406 is in a retracted state, and the fourth clamping member 408 is in a retracted state. Exemplarily, when the second position-limiting portion 41 is in the second position, the third clamping member 406 is retracted to the outside of the first portion 211, and the fourth clamping member 408 is retracted to the outside of the second portion 212.

[0121] Specifically, combined Figure 7 As shown, when the first limiting portion 40 is in the first position described in the above embodiment, the first telescopic member 403 and the second telescopic member can move in a direction toward the accommodation portion 20 ( Figure 7 The first clamping member 404 extends from the first through hole 213 into the accommodating portion 20 to abut against one side of an empty frame 2, and the second clamping member 407 extends from the second through hole 214 into the accommodating portion 20 to abut against the other side of an empty frame 2, so as to limit the downward movement of the empty frame 2 along the first direction. That is, when the first limiting portion 40 is in the first position, the first clamping member 404 and the second clamping member 407 respectively support the opposite sides of the same empty frame 2.

[0122] When the first limiting portion 40 is at the second position described in the above embodiment, the first telescopic member 403 and the second telescopic member can move in a direction away from the accommodation portion 20 ( Figure 7 The first clamping member 404 is moved in the direction of C and D in the middle (as shown in the direction of C and D in the middle), so that the first clamping member 404 is retracted from the first through hole 213 and separated from one side of an empty frame 2, and the second clamping member 407 is retracted from the second through hole 214 and separated from the other side of an empty frame 2, so that the empty frame 2 moves downward along the first direction. That is, when the first limiting portion 40 is in the second position, the first clamping member 404 and the second clamping member 407 are separated from the opposite sides of the same empty frame 2 respectively.

[0123] When the second limiting portion 41 is at the third position as described in the above embodiment, the third telescopic member 405 and the fourth telescopic member can move in a direction toward the accommodation portion 20 ( Figure 7 The third clamping member 406 extends from the first through hole 213 into the accommodating portion 20 and abuts against one side of the empty frame 2, and the fourth clamping member 408 extends from the second through hole 214 into the accommodating portion 20 and abuts against the other side of the empty frame 2, so as to limit the downward movement of the empty frame 2 along the first direction. That is, when the second limiting portion 41 is at the third position, the third clamping member 406 and the fourth clamping member 408 respectively support the opposite sides of the same empty frame 2.

[0124] When the second limiting portion 41 is at the fourth position described in the above embodiment, the third telescopic member 405 and the fourth telescopic member can move in a direction away from the accommodation portion 20 ( Figure 7 The third clamping member 406 is retracted from the first through hole 213 and separated from one side of an empty frame 2, and the fourth clamping member 408 is retracted from the second through hole 214 and separated from the other side of an empty frame 2, so that an empty frame 2 moves downward along the first direction until it is carried by the first transmission part 30. That is, when the second limiting part 41 is at the fourth position, the third clamping member 406 and the fourth clamping member 408 are respectively separated from the opposite sides of the same empty frame 2 to complete the frame disassembly, and are output from the frame outlet 22 by the first transmission part 30 for passengers to take and place their luggage for security inspection.

[0125] It should be noted that the structures of the first limiting portion 40 and the second limiting portion 41 of the present application are not limited thereto, and any limiting portion structure capable of switching between the first position, the second position, the third position and the fourth position mentioned above belongs to the protection scope of the present application. For example, the first limiting portion 40 and the second limiting portion 41 are electric push rod structures respectively.

[0126] Continue to refer Figure 7 In the present application, the first clamping member 404 is arranged parallel to the third clamping member 406 , and the second clamping member 407 is arranged parallel to the fourth clamping member 408 .

[0127] In some possible implementations, the first clamping member 404 and the third clamping member 406 are respectively arranged along the fourth direction ( Figure 7 The second clamping member 407 and the fourth clamping member 408 extend along the fifth direction ( Figure 7 The fourth direction is shown in the direction A in the middle) and extends toward the top of the accommodating portion 20. The fourth direction is consistent with the first direction ( Figure 7 The angle between the fifth direction and the first direction is the first acute angle, the angle between the fifth direction and the first direction is the second acute angle, and the first acute angle is equal to the second acute angle. After such arrangement, when the first clamping member 404, the second clamping member 407, the third clamping member 406 and the fourth clamping member 408 are in the extended state, they can well support the corresponding empty frame 2. Exemplarily, the values ​​of the first acute angle and the second acute angle are between 0° and 45°.

[0128] In some possible implementations, such as Figure 4 , Figures 7 to 9 As shown, the first clamping member 404, the second clamping member 407, the third clamping member 406 and the fourth clamping member 408 of the present application are in sheet shape. When the first position-limiting portion 40 is in the first position, the first clamping member 404 and the second clamping member 407 can abut against the outer edge of an empty frame 2; when the second position-limiting portion 41 is in the third position, the third clamping member 406 and the fourth clamping member 408 can abut against the outer edge of an empty frame 2.

[0129] As mentioned above, the first limiting portion 40 is in the first position, and the first limiting portion 40 abuts against an empty frame 2; the second limiting portion 41 is in the third position, and the second limiting portion 41 abuts against an empty frame 2; an empty frame 2 abutting against the first limiting portion 40 is located inside an empty frame 2 abutting against the second limiting portion 41. In the present application, along the first direction, the distance between the first clamping member 404 and the third clamping member 406, and the distance between the second clamping member 407 and the fourth clamping member 408 satisfy: the outer edge of the lower empty frame 2 of any two adjacent stacked empty frames 2 can abut against the third clamping member 406 and the fourth clamping member 408, and the outer edge of the upper empty frame 2 can abut against the first clamping member 404 and the second clamping member 407.

[0130] After such arrangement, when multiple empty frames 2 are supported by the third clamp 406 and the fourth clamp 408 in the third position, the third clamp 406 and the fourth clamp 408 abut against the outer edge of the bottom empty frame 2 (i.e., the lower empty frame 2) of the multiple empty frames 2. At this time, when the first clamp 404 and the second clamp 407 are controlled to switch to the first position, the first clamp 404 and the second clamp 407 can just abut against the outer edge of an empty frame 2 (i.e., the upper empty frame 2) above the bottom empty frame 2 (i.e., the lower empty frame 2).

[0131] Alternatively, when there is no empty frame 2 abutting against the third clamping member 406 and the fourth clamping member 408, the first clamping member 404 and the second clamping member 407 abut against the outer edge of the bottom empty frame 2 (i.e., the lower empty frame 2) of the plurality of empty frames 2, and when the first clamping member 404 and the second clamping member 407 are controlled to switch to the second position, the plurality of empty frames 2 move downward along the first direction to be supported by the third clamping member 406 and the fourth clamping member 408 located at the third position; the third clamping member 406 and the fourth clamping member 408 abut against the outer edge of the bottom empty frame 2 (i.e., the lower empty frame 2) of the plurality of empty frames 2, and when the first clamping member 404 and the second clamping member 407 are controlled to switch to the first position, the first clamping member 404 and the second clamping member 407 can just abut against the outer edge of an empty frame 2 (i.e., the upper empty frame 2) above the bottom empty frame 2 (i.e., the lower empty frame 2). This facilitates the above-mentioned frame removal operation.

[0132] Exemplary, reference Figure 8 and Fig. 9 , the first electric cylinder 401 of the present application is installed on the side of the main body 10 opposite to the first part 211 through the first mounting portion 4011, and the third electric cylinder 402 is installed on the side of the main body 10 opposite to the first part 211 through the second mounting portion 4021. Similarly, the second electric cylinder 411 of the present application is installed on the side of the main body 10 opposite to the second part 212 through the third mounting portion (with the same structure as the first mounting portion 4011), and the fourth electric cylinder 412 is installed on the side of the main body 10 opposite to the second part 212 through the fourth mounting portion (with the same structure as the second mounting portion 4021).

[0133] Specifically, the first electric cylinder 401 is mounted on the first mounting portion 4011 through the first gasket 4012, and the third electric cylinder 402 is mounted on the second mounting portion 4021 through the second gasket 4022. The second electric cylinder 411 is mounted on the third mounting portion through the third gasket (having the same structure as the first gasket 4012), and the fourth electric cylinder 412 is mounted on the fourth mounting portion through the fourth gasket (having the same structure as the second gasket 4022).

[0134] By changing the number of first gaskets 4012 (increasing or decreasing), the height at which the first electric cylinder 401 is installed on the first mounting portion 4011 can be changed, that is, the distance of the first electric cylinder 401 in the first direction can be changed. This is equivalent to adjusting the distance of the first electric cylinder 401 in the first direction (increasing or decreasing) by adjusting the number of first gaskets 4012, thereby changing the height of the first clamping member 404 in the first direction. By changing the number of third gaskets (increasing or decreasing), the height at which the second electric cylinder 411 is installed on the third mounting portion can be changed, that is, the distance of the second electric cylinder 411 in the first direction can be changed. This is equivalent to adjusting the distance of the second electric cylinder 411 in the first direction (increasing or decreasing) by adjusting the number of third gaskets, thereby changing the height of the second clamping member 407 in the first direction.

[0135] This means that the height of the first position-limiting portion 40 in the first direction is adjustable. With this arrangement, it can be ensured that when the first position-limiting portion 40 is in the first position, the first clamping member 404 and the second clamping member 407 can abut against the outer edge of an empty frame 2. The first clamping member 404 and the second clamping member 407 will not fail to abut against the outer edge of an empty frame 2 due to a processing error of the empty frame 2 or a processing error of the first position-limiting portion 40.

[0136] Similarly, by changing the number of second gaskets 4022 (increasing or decreasing), the height at which the third electric cylinder 402 is installed on the second mounting portion 4021 can be changed, that is, the distance of the third electric cylinder 402 in the first direction can be changed. This is equivalent to adjusting the distance of the third electric cylinder 402 in the first direction (increasing or decreasing) by adjusting the number of second gaskets 4022, thereby changing the height of the third clamping member 406 in the first direction. By changing the number of fourth gaskets (increasing or decreasing), the height at which the fourth electric cylinder 412 is installed on the fourth mounting portion can be changed, that is, the distance of the fourth electric cylinder 412 in the first direction can be changed. This is equivalent to adjusting the distance of the fourth electric cylinder 412 in the first direction (increasing or decreasing) by adjusting the number of fourth gaskets, thereby changing the height of the fourth clamping member 408 in the first direction.

[0137] This means that the height of the second position-limiting portion 41 in the first direction is adjustable. After such arrangement, when the second position-limiting portion 41 is in the third position, the third clamping member 406 and the fourth clamping member 408 can abut against the outer edge of an empty frame 2. The third clamping member 406 and the fourth clamping member 408 will not fail to abut against the outer edge of an empty frame 2 due to a processing error of the empty frame 2 or a processing error of the second position-limiting portion 41.

[0138] Furthermore, it can be ensured that, along the first direction, the distance between the first clip 404 and the third clip 406, and the distance between the second clip 407 and the fourth clip 408 satisfy: the outer edge of the lower empty frame 2 in any two adjacent stacked empty frames 2 can abut against the third clip 406 and the fourth clip 408, and the outer edge of the upper empty frame 2 can abut against the first clip 404 and the second clip 407.

[0139] Continue to refer Figure 2 and Fig.13 , the frame disassembling device 1 of the present application further includes: a first detection hole 51, a second detection hole 52, a third detection hole 53, a fourth detection hole 54 and a fifth detection hole 55. The first detection hole 51, the second detection hole 52, the third detection hole 53, the fourth detection hole 54 and the fifth detection hole 55 are all connected to the accommodating portion 20, and the first detection hole 51, the second detection hole 52, the third detection hole 53, the fourth detection hole 54 and the fifth detection hole 55 can respectively expose the empty frame 2 at the corresponding position in the accommodating portion 20. Exemplarily, the first detection hole 51, the second detection hole 52, the third detection hole 53, the fourth detection hole 54 and the fifth detection hole 55 are respectively provided on the first part 211 and the second part 212 of the accommodating portion 20.

[0140] Specifically, a first sensor is provided at the first detection hole 51 of the present application, and the first sensor is used to detect whether there is an empty frame 2 at a first height, and along the first direction, the first height is higher than the height at the position of the first limit portion 40. That is, the first sensor is used to detect whether the number of empty frames 2 supported by the first limit portion 40 exceeds the allowed number. In other words, the first sensor is used to detect whether the empty frames 2 collected in the accommodating portion 20 overflow, and if so, an alarm is issued. This prevents the second limit portion 41 from being unable to remove the frame in time or the frame removal is abnormal, resulting in more and more empty frames 2 supported by the first limit portion 40.

[0141] Exemplarily, in the process of collecting the empty frames 2 in the receiving portion 20 of the present application, the staff can manually put the empty frames 2 into the receiving portion 20. For example, after the first limit portion 40 supports five empty frames 2, the first height is reached. At this time, if the first sensor detects that there are empty frames 2 at the first height, the empty frames 2 cannot be manually put into the receiving portion 20. If the first limit portion 40 supports four empty frames 2, at this time, the first sensor detects that there are no empty frames 2 at the first height, then one empty frame 2 can be manually put into the receiving portion 20. The number of empty frames 2 collected at the first height is not limited to this, and the corresponding setting is made according to actual needs.

[0142] The second detection hole 52 is provided with a second sensor, and the second sensor is used to detect whether there is an empty frame 2 at a second height, the second height is less than the first height, and the second height is higher than the height at which the first limit portion 40 is located. In the present application, the second sensor also detects whether the number of empty frames 2 supported by the first limit portion 40 exceeds the allowed number. The difference is that if the second sensor detects that there is an empty frame 2 at the second height, the empty frame 2 can no longer be automatically placed into the accommodating portion 20.

[0143] For example, the second transmission part 50 described later is controlled to stop transmitting the empty frame 2 into the receiving part 20. For example, after the first limit part 40 supports four empty frames 2, the second height is reached. At this time, if the second sensor detects that there is an empty frame 2 at the second height, the empty frame 2 cannot be automatically placed into the receiving part 20. If the first limit part 40 supports three empty frames 2, at this time, the second sensor detects that there is no empty frame 2 at the second height, then one empty frame 2 can be automatically placed into the receiving part 20. The number of empty frames 2 collected at the second height is not limited to this, and the corresponding setting is made according to actual needs.

[0144] The third detection hole 53 is provided with a third sensor, and the third sensor is used to detect whether there is an empty frame 2 that abuts against the first limit portion 40. On the one hand, when the third sensor detects that there is an empty frame 2 that abuts against the first limit portion 40, the first limit portion 40 can be controlled to switch from the first position to the second position to provide the empty frame 2 to the second limit portion 41 for the frame removal operation. On the other hand, when the third sensor detects that there is no empty frame 2 that abuts against the first limit portion 40, the second transmission portion 50 can be controlled to continue to transport the empty frame 2 to the accommodating portion 20; the first limit portion 40 can also be controlled to switch from the second position to the first position to abut against the empty frame 2.

[0145] The fourth detection hole 54 is provided with a fourth sensor, and the fourth sensor is used to detect whether there is an empty frame 2 that abuts against the second limiter 41. When the fourth sensor detects that there is an empty frame 2 that abuts against the second limiter 41, the second limiter 41 can be controlled to switch from the third position to the fourth position to perform the frame removal operation. When the fourth sensor detects that there is no empty frame 2 that abuts against the second limiter 41, the second limiter 41 can be controlled to switch from the fourth position to the third position to receive a new empty frame 2 to complete the frame removal operation.

[0146] A fifth sensor is provided at the fifth detection hole 55, and the fifth sensor is used to detect whether the area corresponding to the first transmission part 30 and the receiving part 20 carries the empty frame 2. Exemplarily, the area corresponding to the first transmission part 30 and the receiving part 20 is the area where the downward projections of the first transmission part 30 and the receiving part 20 along the first direction overlap.

[0147] When the second position-limiting part 41 is controlled to switch from the third position to the fourth position, the empty frame 2 separated from the second position-limiting part 41 will fall onto the first transmission part 30 along the first direction. When the fifth sensor detects that the area corresponding to the first transmission part 30 and the receiving part 20 carries an empty frame 2, it means that the empty frame 2 has not been completely transmitted out. At this time, the second position-limiting part 41 is controlled to be in the third position without removing the frame. When the fifth sensor detects that the area corresponding to the first transmission part 30 and the receiving part 20 carries no empty frame 2, the second position-limiting part 41 can be controlled to be in the fourth position for removing the frame.

[0148] In some possible implementations, each sensor can emit a laser line to the outer edge of the empty frame 2 to perform corresponding detection. This arrangement can improve the detection accuracy of each sensor.

[0149] In some possible implementations, such as Fig.13 As shown, the number of the above-mentioned fifth detection holes 55 is two, and a fifth sensor is provided at each fifth detection hole 55. The two fifth sensors are arranged at intervals along the second direction and correspond to the areas corresponding to the first transmission part 30 and the accommodating part 20; along the second direction, the detection distance between the two fifth sensors is a first value, the width of the area corresponding to the first transmission part 30 and the accommodating part 20 is a second value, and the difference between the first value and the second value is within a set range.

[0150] It is equivalent to that two fifth sensors are arranged on the frame dismantling device 1. After such arrangement, it can accurately detect whether the area corresponding to the first transmission part 30 and the receiving part 20 carries an empty frame 2. It prevents the existence of a detection blind spot, which causes the fifth sensor to feedback that the area corresponding to the first transmission part 30 and the receiving part 20 does not carry an empty frame 2, but actually carries an empty frame 2, causing the second limit part 41 to erroneously dismantle the frame, and collide with the empty frame 2 on the first transmission part 30 that has not been completely transmitted from the frame outlet 22, causing the frame dismantling device 1 to malfunction.

[0151] In some possible implementations, the first value is equal to the second value, that is, the detection distance between the two fifth sensors is equal to the width of the area corresponding to the first transmission portion 30 and the accommodation portion 20 .

[0152] In some possible implementations, the first transmission unit 30 includes: a plurality of electric rollers 31 distributed along the second direction. The electric rollers 31 are connected to each other through belts 311. The empty frame 2 separated from the second limiting unit 41 falls onto the electric rollers 31 and is transmitted by the electric rollers 31.

[0153] In some possible implementations, reference Fig.14 The de-framing device 1 further includes a second transmission unit 50, which transmits the second transmission unit 50 along the first direction ( Fig.14The second transmission part 50 is used to transmit the empty frame 2 (shown in the X direction) to the frame inlet 21. Fig.14 2. The M direction shows the transmission direction). Exemplarily, the structure of the second transmission part 50 is the same as that of the first transmission part 30, that is, the second transmission part 50 includes: a plurality of electric rollers 50a distributed along the second direction.

[0154] The present application also provides a security inspection system, comprising the frame removal device described in any of the above embodiments.

[0155] refer to Fig.15 The present application also provides a de-framing method, using the de-framing device 1 described in any of the above embodiments. The de-framing method of the present application includes the following steps:

[0156] S101: Control the first limiting portion 40 to be in the second position and the second limiting portion 41 to be in the third position.

[0157] In the present application, when the frame removal device 1 is in the original state (i.e., when the frame removal operation is not performed), the first limit portion 40 is in the first position, and the second limit portion 41 is in the third position. For example, the first clamping member 404, the second clamping member 407, the third clamping member 406, and the fourth clamping member 408 are all in the extended state.

[0158] When the frame removal operation is required, the first limiting portion 40 is controlled to be in the second position and the second limiting portion 41 is controlled to be in the third position, and the empty frame 2 is transferred to the frame entrance 21 of the accommodating portion 20, and the second limiting portion 41 and an empty frame 2 inserted from the frame entrance 21 are abutted against each other, and at least one empty frame 2 is stacked against the second limiting portion 41.

[0159] Exemplarily, a staff member manually places an empty frame 2 into the receiving portion 20 in advance, and the empty frame 2 is supported on the second limiting portion 41. Then, the second transmission portion 50 is controlled to convey the empty frame 2 to the receiving portion 20. At this time, the first limiting portion 40 is in the second position, and at least one empty frame 2 transmitted by the second transmission portion 50 to the frame inlet 21 moves downward along the first direction and is stacked in the empty frame 2 that abuts against the second limiting portion 41. Placing an empty frame 2 in the receiving portion 20 in advance facilitates subsequent empty frames 2 to stably fall into the receiving portion 20 and be stacked in a pre-placed empty frame. In other words, a pre-placed empty frame plays a role in guiding the collection of empty frames.

[0160] S102: Control the first limiting portion 40 to be in the first position and the second limiting portion 41 to be in the third position.

[0161] After the second limiting portion 41 supports at least two empty frames 2, the first limiting portion 40 is controlled to be in the first position and the second limiting portion 41 is controlled to be in the third position. Exemplarily, the first limiting portion 40 abuts against the empty frames 2 stacked in the empty frames 2 abutting against the second limiting portion 41. The second transporting portion 50 can continue to transport the empty frames 2 to the frame entry 21, and the empty frames 2 abutting against the first limiting portion 40 can stack more than one empty frame 2 put in from the frame entry 21.

[0162] At this time, the first limiting portion 40 supports at least one empty frame 2, and the second limiting portion 41 supports one empty frame 2, so that the frame removal operation can be performed.

[0163] S103: Control the first limiting portion 40 to be in the first position and the second limiting portion 41 to be in the fourth position.

[0164] When removing the frame, the first limiting portion 40 is located at the first position, the second limiting portion 41 is located at the fourth position, and an empty frame 2 abutting against the second limiting portion 41 is separated from the second limiting portion 41, and moves downward along the first direction until it is carried by the first transmission portion 30. The first transmission portion 30 outputs the empty frame 2 from the frame outlet 22 along the second direction, completing a frame removing operation.

[0165] S104: Control the first limiting portion 40 to be in the first position and the second limiting portion 41 to be in the third position.

[0166] When the second limiter 41 is in the fourth position, after the frame removal operation is completed, a new frame removal operation needs to be continued. At this time, the first limiter 40 is controlled to be in the first position and the second limiter 41 is in the third position. After the second limiter 41 is switched to the third position, it can receive the empty frame 2 supported by the first limiter 40 again, that is, it is necessary to control the first limiter 40 to transfer a new empty frame 2 to the second limiter 41.

[0167] S105: Control the first limiting portion 40 to be in the second position and the second limiting portion 41 to be in the third position.

[0168] The first limiting part 40 is controlled to be in the second position, and the second limiting part 41 is controlled to be in the third position, and all the empty frames 2 that are against the first limiting part 40 are separated from the first limiting part 40, and move downward along the first direction to be against the second limiting part 41. At this time, all the empty frames 2 supported by the first limiting part 40 are supported by the second limiting part 41. The second limiting part 41 is against the bottom empty frame 2 of all the empty frames 2, and the next step is to remove the bottom empty frame 2, and the remaining empty frames 2 need to continue to be supported by the first limiting part 40. Therefore, it is necessary to control the first limiting part 40 to switch to the first position.

[0169] S106: Control the first limiting portion 40 to be in the first position and the second limiting portion 41 to be in the third position.

[0170] The de-framing operation is to operate the stacked empty frames 2 one by one, that is, to separate the empty frames from the second limiting portion 41 one by one. That is, when the second limiting portion 41 performs the de-framing operation, it supports one empty frame 2, and the remaining empty frames 2 are supported by the first limiting portion 40. Therefore, the first limiting portion 40 is controlled to be in the first position, and the second limiting portion 41 is controlled to be in the third position, and the first limiting portion 40 and the empty frames 2 stacked in the empty frame 2 abutting against the second limiting portion 41 are abutted. At this time, the second limiting portion 41 supports one empty frame 2, and the remaining empty frames 2 are supported by the first limiting portion 40.

[0171] In this state, the second limiter 41 can continue to perform the frame removal operation, that is, the first limiter 40 is controlled to be in the first position and the second limiter 41 is controlled to be in the fourth position, that is, the above S103 is repeated, and then the above S104 to S106 are repeated.

[0172] Thus, after continuously repeating the above S103 to S106, multiple frame dismantling operations are completed. The first limiter 40 is continuously controlled to switch between the first position and the second position (for example, the first electric cylinder 401 is controlled to drive the first clamping member 404 to extend and retract, and the second electric cylinder 411 is controlled to drive the second clamping member 407 to extend and retract), and the second limiter 41 is switched between the third position and the fourth position (for example, the third electric cylinder 402 is controlled to drive the third clamping member 406 to extend and retract, and the fourth electric cylinder 412 is controlled to drive the fourth clamping member 408 to extend and retract). When the frame dismantling conditions are met (the first limiter 40 supports at least one empty frame 2, and the second limiter 41 supports one empty frame 2), the empty frames 2 collected from the frame inlet 21 to the accommodating portion 20 of the frame dismantling device 1 are dismantled one by one, and then the first transmission unit 30 outputs the empty frames 2 from the frame outlet 22, and the empty frames 2 are transmitted to passengers one by one, so that the passengers can take them and place their luggage for security inspection, thereby improving the security inspection efficiency.

[0173] In a series of possible implementations, when the sensors (first sensor, second sensor, third sensor, fourth sensor and fifth sensor) in the frame removal device 1 described in any of the above embodiments are used:

[0174] When the first sensor detects that there is an empty frame 2 at the first height, the manual transfer of the empty frame 2 to the frame inlet 21 of the receiving portion 20 is stopped. As mentioned above, the first sensor is used to detect whether the empty frames 2 collected in the receiving portion 20 overflow, and if so, an alarm is issued. Manually putting the empty frame 2 into the receiving portion 20 is stopped to prevent the second limiter 41 from removing the frame in time or the frame removal is abnormal, resulting in more and more empty frames 2 supported by the first limiter 40.

[0175] When the second sensor detects that there is an empty frame 2 at the second height, the automatic transmission of the empty frame 2 to the frame inlet 21 of the receiving portion 20 is stopped. As mentioned above, the second sensor is used to detect whether the empty frames 2 collected in the receiving portion 20 overflow, and if so, an alarm is issued. Automatically (for example, by the second transmission portion 50) putting the empty frame 2 into the receiving portion 20 is stopped to prevent the second limiting portion 41 from removing the frame in time or the frame removal is abnormal, resulting in more and more empty frames 2 supported by the first limiting portion 40.

[0176] When the third sensor detects that there is an empty frame 2 abutting against the first position-limiting portion 40, and the fourth sensor detects that there is no empty frame 2 abutting against the second position-limiting portion 41, and the second position-limiting portion 41 is in the third position, the first position-limiting portion 40 is controlled to be in the second position. On the one hand, the first position-limiting portion 40 can be controlled to switch from the first position to the second position to provide an empty frame 2 to the second position-limiting portion 41, for example, the above-mentioned S105 is performed to add a new empty frame 2 to the second position-limiting portion 41 to perform the frame removal operation.

[0177] On the other hand, when the third sensor detects that there is no empty frame 2 that abuts against the first limiting portion 40, the second conveying portion 50 can be controlled to continue conveying the empty frame 2 to the accommodating portion 20. At this time, the first limiting portion 40 can be in the first position, and the empty frame 2 is carried by the first limiting portion 40; or, the first limiting portion 40 is in the second position, and the empty frame 2 is carried by the second limiting portion 41, for example, performing the above-mentioned S101; the first limiting portion 40 can also be controlled to switch from the second position to the first position to abut against the empty frame 2, for example, performing the above-mentioned S102 or S106.

[0178] When the fourth sensor detects that there is an empty frame 2 that abuts against the second limiter 41, the first limiter 40 is controlled to be in the first position. The frame removal operation can be performed, that is, the second limiter 41 is controlled to be in the fourth position, that is, the above S103 is performed. Alternatively, when the empty frame 2 needs to be supported by the first limiter 40, the above S102 is performed.

[0179] When the fourth sensor detects that there is an empty frame 2 abutting against the second limiter 41, and the fifth sensor detects that the area corresponding to the first transmission part 30 and the receiving part 20 does not carry the empty frame 2, the second limiter 41 is controlled to be in the fourth position and the first limiter 40 is controlled to be in the first position. That is, the frame removal operation can be performed at this time, for example, the above-mentioned S103 is performed.

[0180] When the fourth sensor detects that there is an empty frame 2 that abuts against the second limiter 41, the fifth sensor detects that the area corresponding to the first transmission part 30 and the receiving part 20 carries the empty frame 2, and the second limiter 41 is controlled to be in the third position. At this time, the first transmission part 30 has not completely output the removed empty frame 2 from the frame outlet 22, and the second limiter 41 cannot perform the frame removal operation, and the second limiter 41 needs to be controlled to be in the third position.

[0181] When the fourth sensor detects that there is no empty frame 2 abutting against the second limiter 41, the second limiter 41 is controlled to be in the third position. At this time, the second limiter 41 does not support the empty frame 2, and the empty frame 2 can be transferred to the second limiter 41 to perform the frame removal operation, such as performing the above-mentioned S101 and S104.

[0182] In summary, the frame dismantling method of the present application has high frame dismantling efficiency and improves the security inspection efficiency of passengers.
