It should be understood that when the absolute position of the described object changes, the relative positional relationships they represent may also change accordingly. Therefore, these directional terms should not be construed as limiting the invention.

[0051] When using expressions such as "at least one of A, B, and C," the expression should generally be interpreted in accordance with the meaning commonly understood by a person skilled in the art (e.g., "a system having at least one of A, B, and C" should include, but is not limited to, systems having A alone, having B alone, having C alone, having A and B, having A and C, having B and C, and / or having A, B, and C, etc.). Similarly, when using expressions such as "at least one of A, B, or C," the expression should generally be interpreted in accordance with the meaning commonly understood by a person skilled in the art (e.g., "a system having at least one of A, B, or C" should include, but is not limited to, systems having A alone, having B alone, having C alone, having A and B, having A and C, having B and C, and / or having A, B, and C, etc.).

[0052] Figure 1 This is a perspective view of a transmission device according to an illustrative embodiment of the present invention.

[0053] An illustrative embodiment of the present invention provides a transmission device, such as... Figure 1As shown, the device includes a first conveying mechanism 11, at least one second conveying mechanism 12, a support mechanism, and a drive mechanism. The first conveying mechanism 11 is configured to convey an article along a first direction. The second conveying mechanism 12 is pivotally disposed at the input and / or output of the first conveying mechanism 11 and is configured to rotate between a first position extending along the first direction and a second position forming an angle with the first direction, such that the article is conveyed by the first conveying mechanism or by the first conveying mechanism and at least one second conveying mechanism. The support mechanism is adapted to hold the second conveying mechanism 12 in the first or second position. The drive mechanism is connected to the support mechanism and drives the second conveying mechanism 12 to oscillate between the first and second positions via the support mechanism.

[0054] In one illustrative embodiment, the first direction is characterized as the horizontal direction.

[0055] In detail, the first conveying mechanism 11 is arranged in a horizontal direction, and the items are conveyed along the upper surface of the first conveying mechanism 11.

[0056] Figure 2 yes Figure 1 The side view of the second conveying mechanism 12 in the first position state in the schematic embodiment shown.

[0057] In one illustrative embodiment, when the second conveying mechanism 12 is in the first position, the upper surface of the second conveying mechanism 12 is flush with the upper surface of the first conveying mechanism 11.

[0058] In detail, the second conveying mechanism 12 is configured to convey items along the first direction.

[0059] Furthermore, the length of the second transmission mechanism (e.g.) Figure 2 The L1 shown is greater than the thickness (e.g., L1) Figure 2 As shown in L2). This makes it possible to achieve the desired effect in the first direction (e.g., ...). Figure 2 The second direction (as shown in the horizontal direction) is orthogonal to the horizontal direction (e.g.) Figure 2 In the projection of the vertical direction shown, the distance between the edge of the second conveying mechanism 12 near the first conveying mechanism 11 and the edge away from the first conveying mechanism 11 in the second position state is smaller than the distance in the first position state.

[0060] In this embodiment, in the first position, the second conveying mechanism 12 extends along a first direction to input or output articles. In the second position, the second conveying mechanism 12 rotates relative to the first conveying mechanism 11, such that the end of the second conveying mechanism 12 away from the first conveying mechanism 11 (e.g., ...) Figure 1The upper right and lower left ends shown are closer to the first transmission mechanism 11 in the projection of the second direction than in the first position. Thus, in usage scenarios where the input and / or output ends of the transmission device are close to other external devices, the distance between the outer edge of the second transmission mechanism 12 and other devices can be adjusted by adjusting the relative angle between the second transmission mechanism 12 and the first transmission mechanism 11.

[0061] According to embodiments of this disclosure, such as Figure 1 As shown, the input and output ends of the first transmission mechanism 11 are both equipped with a second transmission mechanism 12.

[0062] In one illustrative embodiment, such as Figure 1 As shown, with Figure 1 The upper right end is used as the input end, with Figure 1 The bottom left end is the output end, and the items are from... Figure 1 The data is transmitted from the upper right to the lower left. It should be understood that the embodiments disclosed herein are not limited thereto.

[0063] For example, the second transmission mechanism 12 is only located at the input end of the first transmission mechanism 11.

[0064] For example, the second transmission mechanism 12 is now located at the output end of the second transmission mechanism 12.

[0065] In this implementation, the conveying mechanism can be configured with appropriate positions and numbers of second conveying mechanisms 12 according to specific usage scenarios to meet the requirements for spacing adjustment with other external devices. This improves the adaptability of the conveying mechanism.

[0066] Figure 3 yes Figure 2 A side view of the second conveying mechanism 12 in the second position state in the schematic embodiment shown;

[0067] According to embodiments of this disclosure, Figure 3 As shown, when the second transmission mechanism 12 is in the second position, the angle between the second transmission mechanism 12 and the first transmission mechanism 11 (as shown) Figure 3 The α shown includes, but is not limited to, 90°. It should be understood that the embodiments of this disclosure are not limited thereto.

[0068] For example, the angle between the second transmission mechanism 12 and the first transmission mechanism 11 can be configured to be any angle between 90° and less than 180° and 180° and less than 270°.

[0069] In one illustrative embodiment, in the second position, the angle between the second transmission mechanism 12 and the first transmission mechanism 11 is configured to be 170°.

[0070] In another illustrative embodiment, in the second position, the angle between the second transmission mechanism 12 and the first transmission mechanism 11 is configured to be 160°.

[0071] In this implementation, based on the relative angle between the second conveying mechanism 12 and the first conveying mechanism 11, in addition to adjusting the distance between the outer edge of the second conveying mechanism 12 and other devices, the conveying direction of the second conveying mechanism 12 relative to the first conveying mechanism 11 can also be adjusted so that the items on the conveying device are conveyed upward or downward along the second conveying mechanism 12 relative to the first direction.

[0072] According to embodiments of this disclosure, such as Figure 3 As shown, the second conveying mechanism 12 is configured to rotate to the second position in a direction away from the conveying surface of the first conveying mechanism 11.

[0073] In one illustrative embodiment, the conveying surface is characterized as the surface of the first conveying mechanism 11 that is in close contact with the article (e.g., Figure 3 (The upper surface shown).

[0074] In detail, the second conveying mechanism 12 is configured to rotate downwards to reach the second position. It should be understood that the embodiments of this disclosure are not limited thereto.

[0075] For example, the second conveying mechanism 12 is configured to rotate upwards to reach the second position. See below and appendix for details. Figure 4 and appendix Figure 5 .

[0076] In this implementation, the rotation direction can be set according to the specific usage scenario of the conveying device. Specifically, for example, in a scenario where other structures are located below the first conveying mechanism 11, the second conveying mechanism 12 can be configured to rotate upwards. As another example, in a scenario where there is a height restriction above the first conveying mechanism 11, the second conveying mechanism 12 can be configured to rotate downwards. This can effectively further improve the adaptability of the conveying device.

[0077] According to embodiments of this disclosure, such as Figure 1 As shown, the first conveying mechanism 11 includes a main support frame 111, a drive motor, a plurality of first transmission rollers 113, and a plurality of conveying components 117. The drive motor 116 is mounted on the main support frame 111, and the plurality of first transmission rollers 113 are mounted parallel to and rotatably on the main support frame 111. The plurality of conveying components 117 are respectively disposed between two adjacent first transmission rollers 113 and between the output shaft of the drive motor 116 and a first transmission roller 113, so that the drive motor 116 drives the plurality of first transmission rollers 113 to rotate synchronously.

[0078] In one illustrative embodiment, the transmission assembly includes a sprocket disposed at the end of the first transmission roller and a chain disposed between the sprockets.

[0079] In detail, two or more adjacent drive rollers are connected by a chain 13 and a sprocket to drive at least a portion of the rollers to rotate in the same direction.

[0080] Furthermore, the rotation of the drive rollers at the same speed or at a different speed can be achieved by setting the outer diameter ratio of the sprockets of each first drive roller 113. It should be understood that the embodiments of this disclosure are not limited thereto.

[0081] According to embodiments of this disclosure, such as Figure 1 As shown, the first transmission mechanism 11 also includes a plurality of auxiliary support frames 115, each of which is disposed between two adjacent first transmission rollers 113 and is adapted to cover at least a portion of the gap between the two adjacent first transmission rollers 113 to prevent items from falling through the gap.

[0082] In one illustrative embodiment, the auxiliary support frame 115 is configured as, but is not limited to, a cubic structure, the upper surface of which is lower than the conveying surface formed by the upper end of the first drive roller 113.

[0083] According to embodiments of this disclosure, such as Figure 2 and Figure 3 As shown, the second conveying mechanism 12 is pivotally mounted on the first drive roller 113 at the edge of the roller conveyor and is configured to rotate about the axis of the first drive roller 113.

[0084] In one illustrative embodiment, the second conveying mechanism 12 includes a base 122, which is pivotally disposed on the same side end of the first conveying mechanism 11 via a rotation axis.

[0085] In detail, the rotating shaft is sleeved inside the first transmission roller 113, and the two ends of the rotating shaft extend from the ends of the first transmission roller 113 on the same side, so as to rotatably connect the machine base 122 to the main support frame 111.

[0086] According to embodiments of this disclosure, such as Figure 2 and Figure 3 As shown, the second conveying mechanism 12 is provided with at least one second transmission roller 121. The second transmission roller 121 is arranged parallel to and spaced apart from the first transmission roller 113 and is axially connected to the first transmission roller 113 so that the second transmission roller 121 and the first transmission roller 113 rotate in the same direction.

[0087] In one illustrative embodiment, the second conveying mechanism 12 includes, but is not limited to, two second drive rollers 121.

[0088] In detail, two second drive rollers 121 are rotatably mounted on the base 122.

[0089] In detail, the end of the second drive roller 121 is provided with a sprocket and is meshed with the first drive roller 113 through a chain 13, which is suitable for transmitting the rotational speed output by the first drive roller 113 to the second drive roller 121 so as to drive the second drive roller 121 and the first drive roller 113 to rotate in the same direction and at the same speed.

[0090] In another illustrative embodiment, the second conveying mechanism 12 includes a plurality of second transmission rollers 121, which are arranged in parallel at intervals on the base 122.

[0091] In detail, each of the second drive rollers 121 is provided with a sprocket at the same end.

[0092] Furthermore, two or more adjacent second drive rollers 121 are connected to a sprocket via a chain 13 to drive at least a portion of the rollers to rotate in the same direction. It should be understood that the embodiments of this disclosure are not limited thereto.

[0093] For example, the first conveying mechanism 11 includes, but is not limited to, a belt conveyor, and the second conveying mechanism 12 includes a roller conveyor.

[0094] Specifically, the rotating shaft is sleeved inside the first belt pulley on the same side of the belt conveyor and the roller conveyor.

[0095] Furthermore, sprockets are provided on the same side ends of the first belt pulley and the second transmission roller 121, and are engaged and connected by a chain 13.

[0096] For example, the first conveying mechanism 11 includes, but is not limited to, a roller conveyor, and the second conveying mechanism 12 includes a conveyor belt machine.

[0097] Specifically, the rotating shaft is sleeved inside the first transmission roller 113.

[0098] Furthermore, a pulley is provided on the same side end of the second belt pulley of the first transmission roller 113 and the second transmission mechanism 12, and is connected by a pulley plate.

[0099] According to embodiments of this disclosure, such as Figure 2 and Figure 3 As shown, the support mechanism includes a first link 123 and a second link 124. One end of the first link 123 is pivotally connected to the second transmission mechanism 12. One end of the second link 124 is pivotally connected to the other end of the first link 123, and the other end of the second link 124 is pivotally connected to the first transmission mechanism 11.

[0100] According to embodiments of this disclosure, such as Figure 2 and Figure 3As shown, one end of the drive mechanism is pivotally mounted on the first transmission mechanism 11, and the other end of the drive mechanism is pivotally mounted on the second link 124.

[0101] In one illustrative embodiment, the end of the first link 123 that is not connected to the second link 124 (e.g.) Figure 2 The upper end shown is pivotally mounted on the same side end face of the base 122 (e.g., the upper end). Figure 2 The lower end face shown), the first end of the second link 124 that is not connected to the first link 123 (as shown in the figure). Figure 2 The lower end shown is pivotally mounted on the drive mechanism bracket 114 located below the first transmission mechanism 11 (the drive mechanism bracket 114 can be connected to the first transmission mechanism 11 or disposed on the working surface below the first transmission mechanism 11).

[0102] In detail, the first transmission mechanism 11 also includes a longitudinal beam 112 perpendicular to the bottom surface of the main support frame 111.

[0103] In one illustrative embodiment, the drive mechanism includes, but is not limited to, an electric actuator 125.

[0104] In detail, the two ends of the electric push rod 125 are pivotally disposed at positions other than the pivots on the longitudinal beam 112 and the second connecting rod 124 that are pivotally connected to the first connecting rod 123.

[0105] In this embodiment, when the electric push rod 125 is retracted, the distant ends of the first link 123 and the second link 124 converge towards each other, causing the second conveying mechanism 12 to rotate downward to the second position. When the electric push rod 125 is extended, the distant ends of the first link 123 and the second link 124 expand away from each other, keeping the second conveying mechanism 12 in the first position. Thus, the electric push rod 125 deflects at a relatively small angle during retraction and extension. Furthermore, when the second conveying mechanism 12 is in the second position, the electric push rod 125 is approximately parallel to the first direction, and the extension directions of the first link 123 and the second link 124 are approximately the same. At this time, the load borne by the electric push rod 125 is smaller than the load of lifting the second conveying mechanism 12 vertically, which is beneficial for the second conveying mechanism 12 to be stably maintained in the second position. It should be understood that the embodiments of this disclosure are not limited thereto.

[0106] For example, the drive mechanism includes, but is not limited to, at least one of hydraulic cylinders, oil cylinders, and other drive devices with telescopic functions.

[0107] Figure 4 This is a schematic diagram of the second conveying mechanism 12 of a conveying device according to another illustrative embodiment of the present invention, in a first position state. Figure 5yes Figure 4 The schematic diagram shown illustrates the second conveying mechanism 12 in its second position state in the exemplary embodiment.

[0108] In another illustrative embodiment, the drive mechanism includes a motor and a rotating disk 126.

[0109] In detail, the rotating disk 126 is connected to the output shaft of the motor so that the rotating disk 126 can be driven to rotate by the motor.

[0110] Furthermore, the rotating disk 126 is arranged longitudinally.

[0111] Furthermore, the support mechanism includes a first link 123 and a second link 124. One end of the first link 123 is pivotally connected to the second transmission mechanism 12. One end of the second link 124 is pivotally connected to the other end of the first link 123, and the other end of the second link 124 extends radially outward along the rotating disk 126 and is fixed to the outer edge of the rotating disk 126 in the circumferential direction.

[0112] In this embodiment, the end connecting the second link 124 and the rotating disk 126 rotates around the axis of the motor's output shaft. Since the relative angle between the second link 124 and the rotating disk 126 is limited, the rotating disk 126 can rotate counterclockwise (e.g., ...). Figure 4 Rotate to Figure 5 (at the position), the first link 123 and the second transmission mechanism 12 can be pushed upward, so that the second transmission mechanism 12 is pushed upward from the bottom to the top, so that the second transmission mechanism 12 rotates upward to the second position.

[0113] Figure 6 This is a schematic diagram of a security inspection system according to an illustrative embodiment of the present invention.

[0114] An illustrative embodiment of the present invention also provides a security inspection system, such as... Figure 6 As shown, the system includes a security checkpoint 2, a transfer vehicle 3, a first conveying device 4, and a second conveying device 1. The transfer vehicle 3 is movably installed inside the security checkpoint 2. The first conveying device 4 is located outside the security checkpoint 2 and is used to transfer air cargo from the outside to the inside of the security checkpoint 2. The second conveying device 1 is located inside the security checkpoint 2, between the transfer vehicle 3 and the first conveying device 4, and is used to receive air cargo output from the first conveying device 4 and / or to output air cargo into the transfer vehicle 3.

[0115] In one illustrative embodiment, the security checkpoint 2 defines a security check area inside.

[0116] According to embodiments of this disclosure, such as Figure 2As shown, the second transmission device 1 includes a first transmission mechanism 11, and a second transmission mechanism 12 is provided at both the input and output ends of the first transmission mechanism 11.

[0117] According to embodiments of this disclosure, such as Figure 2 As shown, the security checkpoint 2 includes an openable door 22 located at the entrance 21 of the security checkpoint 2. When the second conveying mechanism 12, which is located at the input end of the first conveying mechanism 11, is in a first position, the second conveying mechanism 12 extends from the entrance 21 to receive the air cargo output by the first conveying device 4. When the second conveying mechanism 12, which is located at the input end of the first conveying mechanism 11, is in a second position, the second conveying mechanism 12 retracts from the entrance 21 so that the door 22 can be closed to seal the entrance 21.

[0118] In one illustrative embodiment, the first conveying device 4 includes at least one of a roller conveyor, a belt conveyor, and other conveying mechanisms for conveying articles.

[0119] In detail, the output end of the first transmission device 4 is located outside the entrance 21 of the security check room 2.

[0120] Furthermore, when the second conveying mechanism 12 on the input side of the second conveying device 1 is in the first position, the second conveying device 1 and the first conveying device 4 are in a substantially adjacent state. This substantially adjacent state means that the gap formed between the first conveying device 4 and the second conveying device 1 will not cause the conveyed air cargo to jam or fall. When the second conveying mechanism 12 on the input side of the second conveying device 1 is in the second position, the gap formed between the first conveying device 4 and the second conveying device 1 is greater than the thickness of the accommodating door 22 and can accommodate the door 22 to pass through, so that the door 22 closes the entrance 21.

[0121] In one illustrative embodiment, the door 22 includes, but is not limited to, a roller shutter door that closes from top to bottom. It should be understood that the embodiments of this disclosure are not limited thereto.

[0122] For example, door 22 includes, but is not limited to, a panel door that is closed from the upper right to the lower right.

[0123] For example, door 22 includes, but is not limited to, sliding doors that open to the left and right.

[0124] According to embodiments of this disclosure, such as Figure 2As shown, it also includes detection equipment. When the second conveyor 12, located at the output end of the first conveyor 11, is in a first position, it outputs air cargo to the transfer vehicle 3. When the second conveyor 12, located at the output end of the first conveyor 11, is in a second position, a gap is formed between the second conveyor 12 and the transfer vehicle 3, allowing the transfer vehicle 3 to move towards the conveying equipment to adjust its position and / or direction of travel until the transfer vehicle 3 passes the detection equipment for air cargo detection.

[0125] In one illustrative embodiment, the detection equipment includes, but is not limited to, an X-ray emitting device and a receiving device.
