Therefore, a set of cross-belt sorting lines requires 5 to 10 sets of automatic bag supply tables. The sorting equipment configured in this way not only has a high equipment cost, but also increases the floor area and reduces the effective bag dropping openings. Content of the Utility Model

[0019] The following uses specific specific examples to illustrate the embodiments of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model.

[0020] Referring to Figure 1 and Figure 2 As shown, the present utility model provides a side flat intersection multi-station automatic continuous bag feeding table system for cross-belt sorters, including: a conveying mechanism 1, a positioning plate 2, a first sensor, and a phase-locked controller.

[0021] [[ID=2�]]In this embodiment, the cross-belt sorter (loop-shaped or linear) is a prior art, and its specific structure will not be described in detail here.

[0022] The conveying mechanism 1 includes a multi-station conveyor belt 11, an intermediate conveyor belt 13, and a trapezoidal conveyor belt 12.

[0023] Specifically, the multi-station conveyor belt and the intermediate conveyor belt are respectively linear belt conveyors. The multi-station conveyor belt 11 is arranged at an angle with the cross-belt sorter.

[0024] The output end of the trapezoidal conveyor belt 12 is inclined and attached to the cross-belt sorter. The output end of the trapezoidal conveyor belt 12 is horizontally butted against the cross-belt sorter for finally delivering the packages onto the sorter trolleys.

[0025] The intermediate conveyor belt is arranged between the multi-station conveyor belt and the trapezoidal conveyor belt. The input end of the trapezoidal conveyor belt 12 is aligned with the output end of the intermediate conveyor belt.

[0026] As a preferred embodiment, the trapezoidal conveyor belt 12 includes a plurality of second belts 21. The second belts 21 are arranged in the same direction as the first belt 111. The plurality of second belts 21 are arranged along the width direction of the first belt 111. The lengths of the plurality of second belts 21 gradually increase from one side of the first belt 111 to the other side of the first belt 111. The input ends of the plurality of second belts 21 are aligned.

[0027] In this embodiment, the number of positioning plates 2 is multiple. A plurality of positioning plates 2 are formed on the first belt 111 of the multi-station conveyor belt 11. The positioning plates are integrally formed with the first belt. The positioning plates 2 are arranged along the width direction of the first belt 111. The positioning plates extend throughout the width direction of the first belt. The plurality of positioning plates 2 are arranged at equal intervals. A limiting space for placing packages is formed between two adjacent positioning plates.

[0028] The first sensor is installed on the multi-station conveyor belt 11. The first sensor is used to sense the positioning plate 2. Preferably, the first sensor is a position sensor, and preferably, the first sensor is a photoelectric switch sensor.

[0029] The phase-locked controller is connected to the first motor of the multi-station conveyor belt 11, the first sensor, and the control system of the cross-belt sorting machine.

[0030] Based on the first running speed of the sorting trolley of the cross-belt sorting machine and the second running speed of the positioning plate 2, the phase-locked controller makes the multi-station conveyor belt 11 keep the same phase as the sorting trolley through the first motor of the multi-station conveyor belt 11.

[0031] In this embodiment, a second sensor is installed on the cross-belt sorting machine. The second sensor is used to sense the sorting trolley. The second sensor is connected to the control system of the cross-belt sorting machine. Preferably, the second sensor is a position sensor, and preferably, it is an infrared communication sensor.

[0032] As a preferred embodiment, the side flat-intersection multi-station automatic continuous bag feeding table system for a cross-belt sorting machine of the present invention further includes a belt-type electronic weighing device for weighing. The belt weighing device is arranged between the output end of the multi-station conveyor belt 11 and the input end of the trapezoidal conveyor belt 12.

[0033] In this embodiment, the belt-type electronic weighing device is a belt-type electronic scale 3.

[0034] A light curtain sensor 4 is installed above the intermediate conveyor belt. The light curtain sensor 4 is used to obtain the position of the package on the intermediate conveyor belt (i.e., the center point of the package). The number of intermediate conveyor belts can be multiple. The intermediate conveyor belt is signal-connected to the phase-locked controller. The light curtain sensor is signal-connected to the phase-locked controller.

[0035] The multi-station conveyor belt and the trapezoidal conveyor belt are respectively controlled by independent motors to run at different speeds. While the phase-locked controller controls the phase-synchronous operation of the multi-station conveyor belt and the sorting trolley of the cross-belt sorter, it controls the motors of the trapezoidal conveyor belt and the intermediate conveyor belt according to the package position information detected by the light curtain sensor.

[0036] Based on the position of the above-mentioned package on the intermediate conveyor belt, the phase-locked controller controls the running speeds of the intermediate conveyor belt and the trapezoidal conveyor belt to convey the package to the middle position of the sorting trolley.

[0037] The light curtain sensor is responsible for detecting the length, width of the package and the distance to the left or right on the conveyor belt, that is, detecting the center position of each package. If the speeds of the sorting trolley and the trapezoidal conveyor belt are fixed, as long as the center positions of the packages are different, they will be sent to different position points on the trolley, or even to the junction of two trolleys.

[0038] The phase-locked controller controls the multi-station conveyor belt and the sorting trolley of the cross-belt to be in the same phase.

[0039] According to the signal of the light curtain sensor, the phase-locked controller controls the speed of the trapezoidal conveyor belt motor to adjust the position of the package conveyed to the trolley. At the same time, according to the signal of the light curtain sensor, the phase-locked controller controls the intermediate conveyor belt to adjust the position between consecutive packages. On the one hand, it cooperates with the packages on the trapezoidal conveyor belt, and on the other hand, it ensures that two packages do not appear on the trapezoidal conveyor belt simultaneously during the continuous feeding of packages.

[0040] Therefore, the phase-locked control only controls the phase of the multi-station conveyor belt and the trolley to be consistent, and controls the speeds of the other two motors to be adjusted according to the different center points of the packages to ensure that the center of the package is conveyed to the middle position of the trolley.

[0041] The multi-station automatic continuous package feeding table system for the cross-belt sorter of the present utility model is to continuously feed packages. If the position is incorrect, it is necessary to control and catch up. Moreover, this kind of catching up can only be at one speed for one package. Therefore, it is necessary to control the package speed by the intermediate conveyor belt, and the length of the intermediate conveyor belt is the same as the distance between the center points of two adjacent sorting trolleys.

[0042] The phase-locked controller has a phase-locked speed range and mode selection function. Specifically: the multi-station conveyor belt has a speed upper limit. According to the conditions of manually placing packages, it is generally not advisable to exceed 2M / S. That is to say, when the running speed of the cross-belt sorter is below 2M / S, the controller automatically controls the speed of the multi-station conveyor belt to be consistent with the speed of the sorter and the phase to be consistent. At this time, only one set of multi-station package feeding table device needs to be configured for the cross-belt sorter.

[0043] Once the running speed of the cross-belt sorter exceeds 2 m / s, the speed of the multi-station conveyor belt will no longer increase, and the phase-locked controller will perform selective phase-locked control by means of a motorized docking cart.

[0044] While meeting the maximum efficiency of continuous bag loading at multiple stations, empty carts are reserved for the cross-belt sorter to increase the single-station bag loading platform or use two sets of multi-station bag loading platforms to further improve the unit production capacity.

[0045] Of course, the maximum speed limit of the phase-locked controller can also be set by the user himself.

[0046] In some embodiments, a dynamic weighing device, i.e., a belt-type electronic scale, is installed between the output end of the multi-station conveyor belt 11 and the input end of the trapezoidal conveyor belt 12.

[0047] The side flat-intersection multi-station automatic continuous bag feeding platform system for a cross-belt sorter of the present utility model automatically maintains phase synchronization between the second running speed of the multi-station conveyor belt (i.e., the positioning plate) and the first running speed of the sorting cart of the cross-belt sorter. As long as the multi-station conveyor belt is full of express packages, the sorting cart of the cross-belt sorter can be kept fully loaded, maximizing the production capacity of the cross-belt sorter. The phase-locked controller compensates the speed according to the left and right positions of the express packages to cooperate with the trapezoidal conveyor belt to accurately feed the packages to the center of the belt of the corresponding sorting cart.

[0048] The side flat-intersection multi-station automatic continuous bag feeding platform system for a cross-belt sorter of the present utility model realizes the function of horizontally conveying express packages from the side to the sorting cart through the trapezoidal conveyor belt.

[0049] The side flat-intersection multi-station automatic continuous bag feeding platform system for a cross-belt sorter of the present utility model is provided with a multi-station conveyor belt, and positioning plates are equidistantly arranged on the first belt of the multi-station conveyor belt.

[0050] In addition, the setting of the positioning plate is beneficial for the bag loading personnel to clearly see the bag loading position and is beneficial for limiting the position of the express packages during movement. And a first sensor for sensing the positioning plate is installed on the multi-station conveyor belt. The first sensor is connected to the phase-locked controller to facilitate the control of phase synchronization.

[0051] The side flat-intersection multi-station automatic continuous bag feeding platform system for a cross-belt sorter of the present utility model adopts a phase-locked controller with a phase-locked function to always keep the phase of the positioning plate of the multi-station conveyor belt consistent with that of the sorting cart of the sorter. Only on the basis of realizing this function can continuous alignment of multiple-station express packages be sent onto each sorting cart running at high speed. The prior art feeds bags by means of intermittent conveying of single express packages and intermittent speed regulation for alignment, so continuous bag feeding cannot be achieved.

[0052] When the speed of the cross-belt sorting machine is within 2 m / s, the hourly production capacity is 12,000 pieces. Only one set of the side flat-cross multi-station automatic continuous bag-feeding table system of the present utility model for the cross-belt sorting machine needs to be configured to maximize the production capacity. If the speed exceeds this value, two sets of the side flat-cross multi-station automatic continuous bag-feeding table system of the present utility model for the cross-belt sorting machine need to be configured. Therefore, the sorting equipment with a cross-belt sorting machine configured with a side flat-cross multi-station automatic continuous bag-feeding table system has low cost and small floor area. The position is vacated to set up bag-drop compartments, improving the sorting efficiency.
