Description

Technical Field

[0001] The present invention relates to the technical field of passenger security inspection systems, and in particular to a device and method for continuously and automatically supplying baskets. Background Art

[0002] Airport security is an important part of airport safety. Passengers need to conduct security checks on their luggage before entering the airport. The general practice is that passengers or security inspectors take out the empty tray from the bottom of the sorting table in front of the security inspection machine and place it on the sorting table, and put the hand luggage and scattered items on the tray. The tray passes through the security inspection system, and the security inspector uses the security inspection machine (X-ray inspection) to determine whether the luggage is safe. This process requires passengers or security inspectors to bend down and take the basket from the lower basket system by themselves, which increases the workload of passengers or security inspectors. Patent No. CN114408502B discloses an automatic tray supply device and a tray sorting table and security inspection system with it, which can not only reduce the situation of passengers looking for trays, making the service more humane, but also avoid passengers bending down to take trays. However, this solution needs to wait for the previous luggage basket to enter the conveying channel before starting to complete the supply action of the next luggage basket. The process takes a long time, and the basket supply efficiency cannot meet the use needs of passengers. Summary of the invention

[0041] Furthermore, if Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the guide plate 6 is located between the empty basket return module assembly 2 and the upper conveying assembly 4, and the guide plate 6 includes an upper transverse plate 61, a lower transverse plate 62 and an inclined plate 63.

A side plate 64 is fixedly connected between the end of the upper transverse plate 61 and the end of the lower transverse plate 62, and the side plate 64 is connected to the vertical support rod 12. It should be noted that the "outside" here refers to the side away from the empty basket when the empty basket is limited and corrected, and the "inside" refers to the side close to the empty basket; the distance between the two opposite inclined plates 63 gradually decreases from bottom to top, so as to correct the position of the empty basket in the process of lifting the empty basket; the guide plate 6 is connected to the vertical support rod 12 through the side plate 64, and the side plate 64 is provided with bolt holes, and the side plate 64 is fixed to the vertical support rod 12 by bolts.

[0042] Furthermore, if Figure 2 As shown, two guide plates 6 are located between two first synchronous belts 34 on the same side to facilitate installation of the first synchronous belts 34 . At this time, a long rod is connected to one side of the side plates 64 away from each other, and the other end of the long rod passes through the first synchronous belt 34 and is fixedly connected to the vertical support rod 12 .

[0043] Furthermore, L-shaped connecting plates 211 are symmetrically connected to both ends of the bottom U-shaped support plate 21, and the L-shaped connecting plates 211 are fixedly connected to the vertical support rod 12.

[0044] Furthermore, if Figure 2 , Figure 3 and Fig.11 As shown, a cross bar is provided in the rectangular frame 11 at the bottom, and a first motor 39 is fixed on the cross bar.

The second transmission shaft is rotatably connected to the rotating seat. The first motor 39 is started to drive the first transmission shaft to rotate, so that the second synchronous wheel rotates, and drives the corresponding bottom rotating rod 31 to rotate. By engaging with the first gear 36, the second gear 37 rotates in the opposite direction, thereby driving the second transmission shaft to rotate.

A push-pull plate 421 is connected between the two sliding plates 43, and a pull rod 51 is hinged between the two ends of the rocker 5 and the two push-pull plates 421. When the second motor is started, the rocker 5 can be driven to rotate, and the rotation of the rocker 5 changes the positions of the two ends of the rocker 5, thereby pulling the pull rod 51, so that the push-pull plate 421 moves under the action of the pull rod 51, so that the sliding plate 43 connected to the push-pull plate 421 slides on the fixed rod 42.

[0047] Furthermore, if Figures 7 to 10 As shown, the conveying mechanism includes a third motor 71 and two fixed plates 72. The inner side of the fixed plate 72 is a straight edge.

The rotating column is rotatably connected to the fixed plate 72. A second pulley 74 is coaxially fixedly connected to the rotating column. A belt 75 that can contact the empty basket is transmission-connected to the first pulley 73 and the second pulley 74. Combined with the above Figure 4 As shown, the fixed plate 72 is tilted and fixed at the lower end of the sliding plate 43 so that the belt 75 can clamp the empty basket. When the third motor 71 is started, it drives the rotating column to rotate, thereby rotating the second pulley 74 and driving the belt 75 to move. At this time, the first pulley 73 rotates, and the belts 75 on both sides move, thereby transporting the empty basket clamped therewith from one side to the next work surface; the belt passes through the inner side of one of the first pulleys 73 to tension the belt 75.

[0050] S2, the empty basket lifting assembly 3 lifts the empty basket on the drum 22 upward, the first motor 39 drives the bottom rotating rod 31 to rotate through the first gear 36, the second gear 37, the second synchronous belt 38, etc., so that the first synchronous belt 34 moves, and the supporting plate 35 on the first synchronous belt 34 drives the empty basket to lift upward. During the lifting process, the guide plate 6 is used for guidance and limiting, and the next step is executed;

[0051] S3, when the distance between the bottom of the lowest empty basket and the roller 22 is greater than the height of the empty basket, step S1 is repeated, and when the highest empty basket reaches the upper conveying position, that is, the height position at which the upper conveying assembly 4 is conveying, the empty basket lifting assembly 3 stops working, and the conveying mechanism is in the avoidance position, and the next step is executed;

[0052] S4, the upper conveying component 4 drives the conveying mechanism to convey the empty basket horizontally, the second motor drives the rocker 5 to rotate, driving the two sliding plates 43 to approach each other, so that the conveying mechanism interacts and approaches, and the belt 75 of the conveying mechanism clamps the two sides of the empty basket, and then the third motor 71 is started to control the movement of the belt 75, so as to convey the empty basket to the next work surface. After the conveying is completed, repeat step S2 to convey the next empty basket.
