Description

Technical Field

[0001] The invention relates to a bag dropping control method of a sorting trolley, and in particular to a bag dropping control method of a flip-plate type sorting trolley. Background Art

[0002] In the prior art, the sorting trolley driving the tray to flip and drop the package is usually contact-driven or electromagnetic-driven. When electromagnetic-driven, the sorting trolley stops moving after the delivery position, and the tray is driven to flip after the electromagnetic drive device is powered on. The efficiency is low and the control will be intermittent. At the same time, the line connection is required, and the line will be chaotic during the movement of the sorting trolley. When contact-driven, the sorting trolley contacts the driving part and tilts the driving part to flip the tray, which is noisy and wears a lot, resulting in frequent maintenance. Therefore, a bag drop control method for a flip-plate sorting trolley is proposed. Summary of the invention

[0003] The purpose of the present invention is to solve the above problems and to provide a bag dropping control method for a flip-plate sorting trolley.

[0004] In order to achieve the above object, the present invention provides the following technical solution: a bag drop control method for a flip-plate sorting trolley, which is characterized by: 1) The scanning module identifies the package information and sends it to the control system. The control system knows the location where the package is to be delivered based on the obtained package information; 2) The control system controls the driving mechanism to move the sorting trolley with the parcel according to the delivery location of the parcel. The real-time position of the sorting trolley during its movement is monitored in real time by the position information monitoring module. The real-time position of the sorting trolley combined with the parcel delivery location information is used to determine whether the sorting trolley is close to or has reached the delivery location. 3) When the sorting trolley is close to or at the delivery position, the trigger device drives the first magnet to approach the second magnet on the sorting trolley. When the first magnet approaches the second magnet, the first magnet and the second magnet are in a state of repulsion of the same poles. The repulsion of the same poles is used to push the locking rod of the sorting trolley to rotate based on a fulcrum, so that the locking rod is disengaged from the locking hook on the tray of the sorting trolley. After the locking hook is disengaged, the tray is flipped by the weight of the tray and the package on the tray, thereby realizing contactless package drop.

[0005] In one embodiment, it further includes: 4) After the sorting trolley moves out of the delivery position, the control system controls the trigger device to drive the first magnet to reset and move to the sleep position. At the sleep position, the first magnet and the second magnet on the sorting trolley will not trigger the sorting trolley to drop the package.

[0006] Further preferably, the position where the sorting trolley is running is obtained by calculating the initial position of the sorting trolley in combination with the running speed and running time of the sorting trolley driven by the driving mechanism or by sensing with a position sensor.

[0007] Further preferably, the first magnet is switched between the trigger position and the sleep position by a trigger device through rotation or linear movement. When the first magnet is in the trigger position, the sorting cart passes by and triggers the tray to flip over and drop the package. When the first magnet is in the sleep position, the sorting cart passes by and does not trigger the flip.

[0008] The present invention also proposes another control method. In this method, when the sorting trolley is close to or at the delivery position, the electromagnet is energized, the sorting trolley drives the second magnet to move to the electromagnet and makes the electromagnet and the second magnet in a state of like-pole repulsion. The like-pole repulsion is used to push the locking rod of the sorting trolley to rotate based on a fulcrum, so that the locking rod is disengaged from the locking hook on the tray of the sorting trolley. After the locking hook is disengaged, the tray is flipped by the weight of the tray and the package on the tray, thereby realizing contactless package dropping.

[0009] The beneficial effects of the present invention are as follows: through the configuration of the present invention, it is used to control the precise dropping of packages on the sorting trolley, and at the same time, by switching the position of the first magnet on the contactless trigger device between the trigger position and the sleep position, when the package on the sorting trolley is close to the delivery position where the package needs to be delivered, the control system automatically controls the first magnet to move to the trigger position to trigger the sorting trolley to drop the package, and if the package on the next sorting trolley is not the package delivered to the delivery position, the control system controls the trigger device to drive the first magnet to move to the sleep position or the first magnet in the sleep position does not move, so as to avoid mis-triggering and causing the wrong delivery of the package; BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Next, we will further illustrate the bag dropping control method of the flip-plate sorting trolley described in the present invention with reference to the accompanying drawings.

[0013] It should be noted that all directional indications such as up, down, left, right, front, back, etc. in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly. Example 1

[0014] See also Figure 1-Figure 3 As shown in, a bag drop control method for a flip-plate sorting trolley is characterized by: The package information is identified by the scanning module and sent to the control system. The control system learns the delivery location of the package based on the obtained package information. The package is scanned by a grayscale meter or other scanning equipment such as a barcode scanner. After scanning, the package information is bound to the information of the sorting trolley. In the subsequent delivery process, the control system determines the location of the package by monitoring the location of the sorting trolley. The control system controls the drive mechanism for driving the sorting trolley to start according to the placement position of the package, and drives the sorting trolley with the package to move; the drive mechanism can be an independent drive mechanism that drives the sorting trolley to move alone or an overall drive mechanism that drives several sorting trolleys to move; the drive mechanism can be a motor; During the movement of the sorting trolley, the control system controls the position information monitoring module to monitor the position of the sorting trolley in real time, and at the same time calculates the distance between the sorting trolley and the delivery position in real time in combination with the delivery position information of the package in the delivery position information module; the position of the sorting trolley during operation is obtained by calculating the initial position of the sorting trolley and the running speed and running time of the sorting trolley driven by the driving mechanism or by sensing the position sensor; When the sorting trolley is close to or at the delivery position, the control system controls the trigger device to operate, driving the first magnet 1 to approach the second magnet 2 on the sorting trolley, so that the first magnet 1 moves to the trigger position. When the first magnet 1 is close to the second magnet 2, the first magnet 1 and the second magnet 2 are in a state of same pole relative to each other. At the same time, due to the principle of like poles repelling each other, the locking rod 5 of the sorting trolley is pushed to rotate based on a fulcrum, so that the locking rod 5 is disengaged from the locking hook on the tray of the sorting trolley. After the locking hook is disengaged, the tray is flipped by the weight of the tray and the package on the tray to realize contactless bag dropping; wherein, the sorting trolley is always moving during the process of re-triggering the bag dropping, so as to realize non-stop and contactless bag dropping; of course, according to the working situation, it can also be set that when the sorting trolley arrives at the delivery position, the bag is dropped by controlling the trolley to stop moving, and the trolley is controlled to move after the bag dropping is completed.

[0015] After the sorting trolley moves out of the delivery position, the control system controls the trigger device to drive the first magnet 1 to reset and move to the sleep position. In the sleep position, the first magnet 1 and the second magnet 2 on the sorting trolley will not trigger the sorting trolley to drop the package.

[0016] In one embodiment, the first magnet 1 is switched between a trigger position and a sleep position by a trigger device through rotation or longitudinal movement. When the first magnet 1 is in the trigger position, the sorting trolley will trigger the tray to flip and drop the package when passing by. When the first magnet 1 is in the sleep position, the sorting trolley will not trigger the flip when passing by. The trigger position and the sleep position are both obtained through experiments before use. When in the trigger position, the first magnet 1 and the second magnet 2 can trigger the locking rod 5 to move and unlock the tray through the repulsion of the same poles, so that the tray can be flipped by its own weight and the weight of the package on the tray. When in the sleep position, there is no magnetic relationship between the first magnet 1 and the second magnet 2, so the locking rod 5 will not be triggered to rotate, and the tray will not be flipped. When the rotary switching method is adopted, the trigger device can be any one of the rotary drivers 3 such as a servo, a motor, and a rotary motor. When the upright switching method is adopted, the trigger device can be any one of the other upright drivers 4 such as an electromagnet, an electric push rod, a cylinder, and a hydraulic cylinder. Example 2

[0017] See also Figure 4 As shown in , the difference between this embodiment and embodiment 1 is that in this embodiment, the first magnet 1 is replaced by an electromagnet 6. When dropping a package, when the sorting trolley is close to or at the delivery position, the control system controls the electromagnet 6 to be energized, and the sorting trolley drives the second magnet 2 to move to the electromagnet 6 and makes the electromagnet 6 and the second magnet 2 in a state of like-pole repulsion. The principle of like-pole repulsion is used to push the locking rod of the sorting trolley to rotate based on a fulcrum, so that the locking rod is disengaged from the locking hook on the tray of the sorting trolley. After the locking hook is disengaged, the tray is flipped by the weight of the tray and the package on the tray, thereby realizing contactless package dropping.
