In this embodiment, the diversion module 200 includes a frame 201 for supporting, an endless conveyor chain 202 disposed on the frame 201, a first driver 209, and a guide module disposed inside the endless conveyor chain 202, wherein,

In order to prevent the supporting member 206 from rotating relative to the sliding rod 205, in practice, the supporting member 206 may be configured with at least two through holes 207 so as to be sleeved on at least two sliding rods 205 at the same time, as shown in fig. 5-7, so that the supporting member 206 can be effectively prevented from rotating relative to the sliding rods 205, and the purpose of conveying the detected object smoothly can be achieved.

In order to make the endless conveying chain 202 rotate circularly, in this embodiment, transmission mechanisms are symmetrically disposed on two sides of the frame 201, respectively, and each transmission mechanism includes a transmission wheel rotatably mounted on the frame 201 and an annular transmission member adapted to the transmission wheel, the annular transmission members are tensioned on the two transmission wheels, and two ends of the endless conveying chain 202 are connected to the annular transmission members of the two transmission mechanisms, for example, two ends of each sliding rod 205 can be connected to the annular transmission members on the corresponding sides, respectively; and the first drive 209 may be in driving connection with at least one of the drive wheels, such that the first drive 209 may drive the endless drive member to rotate cyclically about the drive wheel, and thereby drive the endless conveyor chain 202 to rotate cyclically.

In practice, the first driver 209 may employ an electric motor, a pneumatic motor, or the like.

In this embodiment, since the endless conveying chain 202 can drive each supporting component 206 to be conveyed linearly along the direction from the input end 203 to the output end 204, so as to form a conveying line, and in order to divert the articles to be inspected, another conveying line needs to be formed by using a guiding module so as to achieve the purpose of diverting, in the implementation, the guiding module has various embodiments, as an example, the guiding module includes a first rail 301, a diverting mechanism 302 and a second driver 305, as shown in fig. 8-10, wherein the first rail 301 may be disposed at a position corresponding to the upper portion of the endless conveying chain 202 and fixed to the frame, as shown in fig. 8, one end of the first rail 301 may be disposed at a position adapted to the diverting mechanism 302, and the other end may extend to the output end 204, and the first rail 301 includes at least a partially bent segment, as shown in fig. 8 and 9, so that the first rail 301 cannot be formed into a straight shape, thereby achieving the purpose of diverting effectively. Meanwhile, in the present embodiment, the shunting mechanism 302 is configured with a guide rail 303 adapted to the first rail 301, and the second driver 305 is in transmission connection with the shunting mechanism 302, so that the second driver 305 can control whether the guide rail 303 is butted with the first rail 301 by driving the shunting mechanism 302 to move transversely; specifically, the shunt mechanism 302 is movably constrained to the frame 201 and has a degree of freedom to move in a lateral direction of the frame 201; the second driver 305 has various embodiments, for example, the second driver 305 may be an air cylinder, an electric cylinder, a hydraulic cylinder, a linear module, or the like, as shown in fig. 8 and 9 by way of example, in this embodiment, the second driver 305 is an air cylinder, the air cylinder includes a cylinder body fixed to the frame 201, and a push rod disposed on a rod body, and the push rod is connected to the flow dividing mechanism 302 so as to drive the flow dividing mechanism 302 to move laterally by using the extension/contraction of the push rod.

In practice, the shunt mechanism 302 may be a block structure or the like.

In order to allow the support member 206 to be engaged with the guide rail 303 and the first rail 301, the lower end of the support member 206 is configured with a sliding portion 208 that is fitted to the guide rail 303 (also fitted to the first rail 301), as shown in fig. 5 to 7, so that the support member 206 can be brought into sliding engagement with the guide rail 303 and the first rail 301 through the sliding portion 208 to guide the support member 206 to move along the guide rail 303 and the first rail 301, so that the support member 206 can be moved exactly along the conveyance route formed by the first rail 301. In practice, the sliding portion 208 may be configured to fit the guide rail 303 and the first rail 301, for example, the sliding portion 208 may be a restraining bar vertically disposed at the bottom of the supporting member 206, in this case, the guide rail 303 and the first rail 301 may be respectively a guide groove, as shown in fig. 8 and 9, in the case that the guide rail 303 is abutted to the first rail 301, when the supporting member 206 passes through the diversion mechanism 302, the restraining bar at the lower end of the supporting member 206 may smoothly slide into the guide rail 303, and may slide into the first rail 301 under the guidance of the guide rail 303, so that the restraining bar and the supporting member 206 may strictly run along the first rail 301 under the restraining and guiding effects of the first rail 301.

In practical use, when the guide rail 303 is not abutted to the first rail 301, the supporting member 206 (and the article to be inspected thereon) can be driven by the endless conveying chain 202 to move forward to the output end 204 in a straight line, so that a first conveying path can be formed; when the guide rail 303 is abutted against the first rail 301, the supporting member 206 can deviate from the original moving direction through the matching of the sliding portion 208 and the guide rail 303 and move to the output end 204 along the first rail 301, so that a second conveying line can be formed, the conveying direction of the second conveying line is consistent with that of the first conveying line, as shown in fig. 3 and 9, and the second conveying line can be juxtaposed with each other and can be used for conveying normal inspected articles and inspected articles needing to be rechecked respectively, so that the aim of separating the rechecked articles from articles without the need of rechecking is achieved, and the rear-end workers can carry out bag opening and rechecking conveniently. Compared with the prior art, the safety inspection system does not need to transversely shunt the articles to be re-inspected independently and vertically, so that the articles to be re-inspected can be synchronously separated in the forward conveying process, the two articles in the front and at the back with a short effective separation distance are not easy to jam and make mistakes, the efficiency can be improved by improving the conveying speed, and the shunting efficiency is higher than that of the prior art.

It is understood that, since the supporting member 206 can move laterally, the width of the endless conveying chain 202 (or the length of the sliding bar 205) should be greater than or equal to the width of the supporting member 206, while in a preferred embodiment, the width of the sliding bar 205 can be greater than or equal to twice the width of the supporting member 206, as shown in fig. 1 and 10, so that the inspected articles can be output side by side at the output end 204.

In order to make the supporting members 206 have the same initial position at the input end 203 of the endless conveying chain 202, in a more sophisticated scheme, the frame 201 is further provided with a guiding mechanism 400, the guiding mechanism 400 can be arranged at one side of the endless conveying chain 202, as shown in fig. 8-10, the guiding mechanism 400 can be arranged inside the endless conveying chain 202, or at the lower part of the endless conveying chain 202, as shown in fig. 8-10, the guiding mechanism 400 is mainly used for guiding the supporting members 206 to converge at the same position at the front end of the diversion mechanism 302, and the position can correspond to the outlet end of the security inspection machine 100, as shown in fig. 1, that is, the supporting members 206 can converge at the same position when turning back from the lower part of the endless conveying chain 202 to the diversion mechanism 302, so that the supporting members 206 can move to the guiding mechanism 400 along the same track, as shown in fig. 10. Because the supporting member 206 can circularly rotate along with the circulating conveying chain 202, and the supporting member 206 has a degree of freedom of transverse movement, in the process of shunting the detected articles, the supporting member 206 can transversely deviate from the original conveying direction; therefore, by providing the guide mechanism 400, the support members 206 can be converged at the same position at the front end of the flow dividing mechanism 302 under the constraining and guiding effects of the guide mechanism 400, so that the support members 206 can move to the flow dividing mechanism 302 along the same track, so as to achieve flow division or non-flow division at the flow dividing mechanism 302, and meanwhile, the support members 206 are converged at the same position at the front end of the flow dividing mechanism 302 and correspond to the outlet end of the security inspection machine 100, so that the detected articles departing from the security inspection machine 100 can be smoothly transferred to the support members 206, can be continuously conveyed backwards under the driving of the support members 206, achieve flow division or non-flow division at the flow dividing mechanism 302, and achieve accurate matching of the security inspection machine 100.

In practice, the guide mechanism 400 may include a guide member 401 for contacting and guiding the support member 206, and a plurality of brackets 402, the guide member 401 may be fixed to the frame 201 by the brackets 402, one end of the guide member 401 may be disposed at an edge of the endless conveying chain 202, as shown in fig. 8-10, the other end may extend to one side of the flow dividing mechanism 302, and the guide member 401 is disposed obliquely or has a certain arc, when the support member 206 moves forward under rotation of the endless conveying chain 202, especially when the support member 206 rotates to a lower portion of the endless conveying chain 202, an end of the support member 206 may contact and press against the guide member 401, and due to the freedom of the support member 206 to move laterally relative to the sliding rod 205, the support member 206 may move laterally under the constraint of the guide member 401, so that the support members 206 may converge at the same position at the front end of the flow dividing mechanism 302.

To facilitate the use of the security inspection system, in a more sophisticated solution, the security inspection system further comprises a controller, the controller is electrically connected to the second driver 305, and is used for controlling the second driver 305, so as to control the lateral movement of the shunting mechanism 302 by controlling the second driver 305, thereby achieving the purpose of controlling whether the guide track 303 is in butt joint with the first track 301. For example, when the transport path formed by the first track 301 is used as a diversion path, in the actual operation of the present security check system, each article is detected by the security check machine 100, then sequentially moved onto the support members 206 of the endless transport chain 202, and is transported forward along the endless transport chain 202. It is understood that the number of the supporting members 206 occupied by each article is related to the size of the article, and may occupy one supporting member 206, two supporting members 206, three supporting members 206, etc., when an article to be inspected needs to be shunted, when the supporting member 206 supporting the article moves to the position of the shunting mechanism 302, the controller may control the shunting mechanism 302 to operate such that the guide rail 303 is in abutment with the first rail 301, and thus each supporting member 206 supporting the article may sequentially slide into the first rail 301 via the guide rail 303 under the guiding action of the sliding portion 208, thereby achieving the purpose of successfully shunting the article, and after the sliding portion 208 of each supporting member 206 supporting the article slides into the first rail 301, the controller may control the shunting mechanism 302 to operate such that the guide rail 303 is not in abutment with the first rail 301, so that the subsequent supporting member 206 may be conveyed forward along the endless conveyor chain 202 without being guided onto the first rail 301, thereby avoiding shunting the subsequent supporting member 206. For more specific description, a case is enumerated here, for example, a certain article occupies two adjacent supporting components 206, and neither of two inspected articles adjacent to this article needs to be retested, when the two supporting components 206 move to the front of the diverting mechanism 302 with the article to be retested, the controller controls the diverting mechanism 302 to operate, so that the guiding track 303 is butted with the first track 301, so that the sliding portion 208 of the supporting component 206 can be just matched with the guiding track 303, so that the two supporting components 206 can slide into the first track 301 under the guidance of the guiding track 303, and the purpose of diverting is achieved; then, the controller controls the shunting mechanism 302 to act, so that the guide rail 303 is not butted with the first rail 301, and the subsequent supporting component 206 at the position of the shunting mechanism 302 can only be driven by the circulating conveying chain 202 to continue to be conveyed forwards in a straight line and cannot be shunted.

In a more complete scheme, in order to facilitate that a worker sends an instruction to be retested after judging a diagram through a display, in an embodiment, the controller may be connected to a processor of the security inspection machine 100, a virtual trigger button is provided in the display, when retesting is required, the worker presses the trigger button, the processor receives the trigger instruction and sends the trigger instruction to the controller, and the controller may control the shunting mechanism 302 to act according to the trigger instruction, so as to shunt the current article to be inspected onto the first track 301 for retesting. In another embodiment, the inspection device further includes a trigger button of an entity, the trigger button may be disposed on a center console of the security inspection machine 100, the display may also be disposed on the center console, the trigger button is electrically connected to the controller, when a worker needs to perform a retest after judging a drawing through the display, the worker may send an instruction through the trigger button, and after receiving the instruction, the controller may control the shunting mechanism 302 to act, so as to shunt a current article to be inspected onto the first track 301 for the retest.

In practice, the controller may also be electrically connected to the first driver 209 so as to control the rotation speed, start/stop, etc. of the endless conveying chain 202. The controller has various embodiments, and by way of example, the controller may preferably adopt a PLC, a single chip microcomputer or a PC. Of course, the controller may also be an embedded microprocessor, an embedded DSP processor, etc.

In a more sophisticated solution, a buffer table or buffer conveyor belt or the like is provided at the output end 204 of the endless conveyor chain 202 for buffering articles. Of course, in practice, a transition conveying module may be further disposed between the outlet end of the security inspection machine 100 and the diversion module 200, and the transition conveying module has various embodiments, for example, the transition conveying module may adopt a belt conveying mechanism, a ball conveying mechanism, a chain conveying mechanism, a roller conveying mechanism, or the like.

When the article does not need to be rechecked, the diversion mechanism 302 driven by the second driver 305 moves transversely, so that the guide rail 303 can form a dislocation with the end of the first rail 301, the diversion mechanism 302 is prevented from blocking the supporting component 206, and the supporting component 206 separated from the first rail 301 can be conveyed forwards in a straight line under the driving of the endless conveyor chain 202, as shown in fig. 11.
