Description

Technical Field

[0001] The utility model relates to the technical field of automatic detection of express transit bags, in particular to an automatic detection device for express transit bags. Background Art

[0002] At present, during the collection and transfer of express parcels, small-volume express parcels are usually put into a transfer bag. When sorting express parcels at the express transfer station, all the express parcels in the transfer bag need to be taken out and then sorted according to the express address. During the express parcel sorting process, if the express parcels in the transfer bag are not all taken out, the express parcels left in the transfer bag may be lost or the express delivery may be delayed. In order to ensure that all the express parcels in the transfer bag are taken out, it is necessary to check and confirm whether there are any express parcels left in the transfer bag. At present, manual methods are usually used to check each transfer bag after picking up the parcels to see if there are any express parcels left inside. This method of manually checking transfer bags is inefficient, has high labor costs, and is highly subjective, and cannot meet the requirements of the increasingly developed express industry for transfer efficiency, cost control, accuracy, etc. Utility Model Content

[0015] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0016] Example 1

[0017] like Figure 1-3 As shown, this embodiment provides an automatic detection device for express transit bags, which includes two connected conveying mechanisms 7 arranged along a set running direction and an imaging detection system 1, with a gap left between the two conveying mechanisms 7, and the upper surfaces of the two conveying mechanisms 7 are used to convey the express transit bags 3, and the imaging detection system includes a signal transmitter 11 and a signal receiver 12.

[0018] like Figure 1 As shown, when the signal transmitter 11 and the signal receiver 12 of the imaging detection system 1 are located on the same side, the signal transmitter 11 and the signal receiver 12 are both placed in the gap between the two conveying mechanisms 7, and an interference shielding device 2 supported by a support frame is provided directly above the imaging detection system 1. The interference shielding device 2 is located above the conveyed express transit bag 3, and an imaging detection area is constituted directly above the imaging detection system 1. The left and right sides of the interference shielding device 2 extend out of the corresponding left and right sides of the gap between the two conveying mechanisms 7 to cover the imaging detection area.

[0019] In this embodiment, the upper surface of the imaging detection system 1 is lower than the upper surface of the conveying mechanism 7 or the upper surface of the imaging detection system 1 is flush with the upper surface of the conveying mechanism 7, so that the position of the imaging detection system 1 does not affect the passage of the express transfer bag 3 on the conveying mechanism 7.

[0020] The interference shielding device 2 is made of a material with strong wave absorption, and is used to shield the interference of external signals on the imaging detection system, and to absorb the signal passing through the express transfer bag 3, so as to stabilize the imaging environment and imaging effect. The support frame supporting the interference shielding device 2 can be fixed on the ground next to the conveying mechanism 7 or fixed on the supporting structure of the conveying mechanism 7.

[0021] like Figure 2As shown, when the signal transmitter 11 and the signal receiver 12 of the imaging detection system 1 are located on opposite sides, the signal receiver 12 is placed in the gap between the two conveying mechanisms 7, and the signal transmitter 11 is supported by a support frame just above the gap between the two conveying mechanisms 7 and above the conveyed express transfer bag 3, and an imaging detection area is formed between the signal transmitter 11 and the signal receiver 12. The support frame supporting the signal transmitter 11 can be fixed on the ground next to the conveying mechanism 7 or fixed on the support structure of the conveying mechanism 7.

[0022] In this embodiment, the upper surface of the signal receiver 12 is lower than the upper surface of the conveying mechanism 7 or the upper surface of the signal receiver 12 is flush with the upper surface of the conveying mechanism 7, so that the position of the signal receiver 12 does not affect the passage of the express transfer bag 3 on the conveying mechanism 7.

[0023] like Figure 3 As shown, when the signal transmitter 11 and the signal receiver 12 of the imaging detection system 1 are located on opposite sides, the signal transmitter 11 is placed in the gap between the two conveying mechanisms 7, and the signal receiver 12 is supported by a support frame just above the gap between the two conveying mechanisms 7 and above the conveyed express transfer bag 3, and an imaging detection area is formed between the signal transmitter 11 and the signal receiver 12. The support frame supporting the signal receiver 12 can be fixed on the ground next to the conveying mechanism 7 or fixed on the support structure of the conveying mechanism 7.

[0024] In this embodiment, the upper surface of the signal transmitter 11 is lower than the upper surface of the conveying mechanism 7 or the upper surface of the signal transmitter 11 is flush with the upper surface of the conveying mechanism 7, so that the position of the signal transmitter 11 does not affect the passage of the express transfer bag 3 on the conveying mechanism 7.

[0025] The conveying mechanism 7 can be displaced and moved in a set running direction, and can be, but not limited to, guide rail conveying, chain conveying, synchronous belt conveying, belt conveying, slide conveying, and roller conveying.

[0026] The imaging detection system 1 is a millimeter wave linear array imaging system, a terahertz wave linear array imaging system, a millimeter wave surface array imaging system, or a terahertz wave surface array imaging system.

[0027] When the signal transmitter 11 and the signal receiver 12 of the imaging detection system 1 are located on the same side, the working principle of the automatic detection device is as follows: when working, the conveying mechanism 7 runs along the track running direction 501, and the express transfer bag 3 on the conveying mechanism 7 runs along the track running direction 501. When the express transfer bag 3 passes through the gap between the two conveying mechanisms 7 (i.e., the imaging detection area), the signal transmitter 11 transmits a signal to the express transfer bag 3. The signal can penetrate the express transfer bag 3 and be partially reflected by the express transfer bag 3 and the express items in the bag. The signal receiver 12 receives the reflected signal and performs imaging display by processing the signal information. Due to the different transmission, absorption, and reflection of the signal by the express transfer bag 3 and the express items in the bag, the reflected signal differences at different positions are caused, so that the imaging information can present and distinguish whether there are any express items left in the express transfer bag 3.

[0028] When the signal transmitter 11 and the signal receiver 12 of the imaging detection system 1 are located on opposite sides, the working principle of the automatic detection device is as follows: when working, the conveying mechanism 7 runs along the track running direction 501, and the express transit bag 3 on the conveying mechanism 7 runs along the track running direction 501. When the express transit bag 3 passes through the gap between the two conveying mechanisms 7 (i.e., the imaging detection area), the signal transmitting unit 11 transmits a signal to the express transit bag. The signal can penetrate the transit bag and be partially absorbed and reflected by the transit bag and the express items in the bag. The signal receiving unit 12 receives the transmitted signal and performs imaging display by processing the signal information. Due to the different transmission, absorption, and reflection of the signal by the express transit bag 3 and the express items in the bag, the transmission signal differences at different positions are caused, so that the imaging information can present and distinguish whether there are any express items left in the express transit bag 3.

[0029] Example 2

[0030] like Figure 4 As shown, this embodiment provides an automatic detection device for express transit bags, which includes a conveying mechanism 201 arranged along a set running direction and an imaging detection system 202, the upper surface of the conveying mechanism 201 is used to convey the express transit bags 203, and the imaging detection system 202 includes a signal transmitter and a signal receiver.

[0031] The signal transmitter and signal receiver of the imaging detection system 202 are located on the same side. Both the signal transmitter and the signal receiver are placed in the inner cavity of the conveying mechanism 201. An interference shielding device 204 is provided directly above the imaging detection system 202. The interference shielding device 204 is located above the conveyed express transfer bag 203. An imaging detection area is constituted directly above the imaging detection system 202. The left and right sides of the interference shielding device 204 extend from the corresponding left and right sides of the imaging detection system 202 to cover the imaging detection area.

[0032] The interference shielding device 204 is made of a material with strong wave absorption, and is used to shield the interference of external signals on the imaging detection system, and to absorb the signal passing through the express transfer bag 203, so as to stabilize the imaging environment and imaging effect. The support frame supporting the interference shielding device 204 can be fixed on the ground beside the conveying mechanism 1 or fixed on the supporting structure of the conveying mechanism 1.

[0033] The conveyor belt of the conveying mechanism 201 adopts a wave-transmitting conveyor belt, which includes PVC conveyor belt, PU conveyor belt, felt conveyor belt, silicone conveyor belt, canvas conveyor belt, PVK conveyor belt, rubber conveyor belt, and conveyor belts made of other non-metallic non-polar materials.

[0034] The imaging detection system 202 is a millimeter wave linear array imaging system, a terahertz wave linear array imaging system, a millimeter wave surface array imaging system, or a terahertz wave surface array imaging system.

[0035] When working, the conveying mechanism 201 runs along the direction of the track, and the express transfer bag 203 on the conveying mechanism 201 runs along the direction of the track. When the express transfer bag 203 passes through the imaging detection area, the signal transmitter of the imaging detection system 202 transmits a signal to the express transfer bag 203. The signal can penetrate the express transfer bag 203 and be partially reflected by the express transfer bag 203 and the express items in the bag. The signal receiver of the imaging detection system 202 receives the reflected signal and performs imaging display by processing the signal information. Since the express transfer bag 203 and the express items in the bag have different signal transmission, absorption, and reflection conditions, the reflected signals at different positions are different, so that the imaging information can present and distinguish whether there are any express items left in the express transfer bag 203.
