DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings.

[0026] like Figure 1 and 5 As shown, a sorting machine grid parcel automatic output device includes multiple automatic grid pushing devices. Multiple automatic grid pushing devices are arranged in sequence at each output port of the parcel sorting machine, and are used to receive parcels sorted by the parcel sorting machine, and when the storage upper limit is reached, the stored parcels are output in the form of a pile. The automatic grid pushing device includes a frame 1, a belt conveyor mechanism 3, a parcel quantity detection component 4 and a flip door panel component 2. The frame 1 includes a base 1-1, and two grid side panels 1-2, an end closing plate 1-5, a tail end guide plate 1-4, a support frame 1-6, a door panel mounting frame 1-7 and a belt 3-1 side beam 1-8 installed on the base 1-1; a support seat is installed at the bottom of the four legs of the base 1-1. The support seat and the base 1-1 form a sliding pair that slides in the vertical direction. A height adjustment mechanism is provided between the support seat and the base 1-1. The height adjustment mechanism includes a support stud and a support nut. The bottom end of the support stud is fixed on the support seat, and the support nut is threadedly connected to the support stud; the bottom of the support foot of the base 1-1 is supported on the support nut. The height of the support foot of the base 1-1 can be adjusted by rotating the support nut.

[0027] The two belt 3-1 side beams 1-8 are respectively installed on both sides of the top of the base 1-1. The belt conveyor mechanism 3 is installed between the two belt 3-1 side beams 1-8. The support frame 1-6 is fixed on the two belt 3-1 side beams 1-8, and is used to support the grid side panels 1-2, the end closing panels 1-5 and the tail end guide panels 1-4; the two grid side panels 1-2 are fixed on both sides inside the support frame 1-6; the two ends of the support frame 1-6 are the closed end and the side output end respectively. The vertically arranged end closing panel 1-5 is fixed to the closed end of the support frame 1-6, and the edges on both sides are fixed to the edges of the two grid side panels 1-2. The door panel mounting frame 1-7 is fixed to the top of the side output end of the support frame 1-6. The top of the door panel 1-3 is rotatably connected to the door panel mounting frame 1-7. The door panel mounting frame 1-7 is installed with an anti-collision strip on the side facing the door panel 1-3, which is used to buffer and limit the return of the door panel mounting frame 1-7. The belt conveyor mechanism 3, the end closing plate 1-5, the door plate 1-3, and the two side panels 1-2 together form a package storage chamber with an open top. Only the door plate 1-3 of the side of the package storage chamber can be opened to facilitate the output of the package. The top edge of the end closing plate 1-5 is installed with a tail end guide plate 1-4. The top of the tail end guide plate 1-4 extends out of the package storage chamber, and the bottom is fixed to the top edge of the end closing plate 1-5; in the conveying direction of the belt conveyor mechanism 3, the inclined surface of the tail end guide plate 1-4 gradually decreases.

[0028] like Figure 1 and 2 As shown, the package quantity detection component 4 is arranged at the top of the side plate 1-2 of the grid close to the parcel sorting machine, and is used to detect the amount of packages piled on the belt conveyor mechanism 3. The package quantity detection component 4 includes a photoelectric sensor 4-1 and a reflector. 4-2 The photoelectric sensor 4-1 and the reflector are respectively fixed on the top of the opposite sides of the two grid side plates 1-2. When the parcels stored in the storage chamber reach the upper limit, the light beam emitted by the photoelectric sensor 4-1 to the reflector is blocked, so that the photoelectric sensor 4-1 cannot receive the reflected light beam. The automatic grid pushing device triggers the grid lock, and the parcel sorting machine stops the continued fall of the parcel.

[0029] like Figure 2 and 3As shown, the flip door panel assembly 2 includes a flip drive assembly and a transmission assembly. The flip drive assembly includes a flip drive motor 2-1, a transmission rod 2-2 and a flip connecting rod 2-3. The transmission rod 2-2 is rotatably connected to the frame 1. The two ends of the flip connecting rod 2-3 are rotatably connected to the outer end of the transmission rod 2-2 and the middle of the door panel 1-3 respectively. The flip connecting rod 2-3 adopts a hexagonal rod. A door panel connecting piece 2-6 is fixed in the middle of one side of the door panel 1-3. A spherical bearing 2-4 is fixed to the outer end of the flip connecting rod 2-3. The spherical bearing 2-4 is rotatably connected to the door panel connecting piece 2-6 through a bearing stop pin 2-5. The flip drive motor 2-1 is fixed to the frame 1, and drives the transmission rod 2-2 to rotate through the transmission assembly.

[0030] The transmission assembly includes a driving pulley 2-7, a connecting shaft, a driven pulley 2-9 and a transmission belt 2-8. The driving pulley 2-7 is fixed to the output shaft of the flip drive motor 2-1. The connecting shaft is rotatably connected to the frame 1 through a bearing seat. The driven pulley 2-9 is fixed to the outer end of the connecting shaft. The driving pulley 2-7 and the driven pulley 2-9 are connected by a transmission belt 2-8. The inner end of the transmission rod 2-2 is fixed to the connecting shaft. Among them, the driving pulley 2-7 and the driven pulley 2-9 are both synchronous pulleys; the transmission belt 2-8 is a synchronous belt.

[0031] like Figure 1 and 2 As shown, the door panel 1-3 is driven to rotate by the flip drive assembly and has two extreme positions, namely the closed extreme position and the conveying extreme position. When the door panel 1-3 is at the closed extreme position, the two side edges of the door panel 1-3 are in contact with the edges of the two grid side panels 1-2 facing away from the parcel sorting machine, and the door panel 1-3, the end closing panel 1-5 and the two grid side panels 1-2 constitute a parcel storage chamber with an open top to store the parcels output by the parcel sorting machine. When the door panel 1-3 is at the conveying extreme position, the side of the parcel storage chamber facing away from the parcel sorting machine is open. The bottom edge of the door panel 1-3 is higher than or parallel to the detection position of the parcel quantity detection component 4. The parcels stored in the parcel storage chamber are output from the side facing away from the parcel sorting machine through the belt conveyor mechanism 3.

[0032] like Figure 2 and 4 As shown, the belt conveyor mechanism 3 includes a belt 3-1, a driving roller, a driven roller, a conveying drive motor 3-2 and a tensioning mechanism. The driving roller and the driven roller are both rotatably connected to the frame 1 and are connected by the belt 3-1. The conveying drive motor 3-2 is fixed to the frame 1. The conveying drive motor 3-2 is connected to the driving roller by a belt transmission. Both ends of the driven roller are provided with a tensioning mechanism for adjusting the distance between the driven roller and the driving roller, thereby preventing the belt 3-1 from being loosened.

[0033] In some embodiments, the tensioning mechanism includes an adjusting plate 3-3 and an adjusting bolt 3-4. Adjusting rods are fixed at both ends of the driven roller. The adjusting plate 3-3 is slidably connected to the frame 1, and the sliding direction is parallel to the conveying direction of the belt conveyor mechanism 3. A clearance hole is provided on the side surface of the adjusting plate 3-3 facing the driven roller. The outer end of the adjusting rod extends into the clearance hole. A threaded hole is provided on the adjusting plate 3-3. The axis of the threaded hole is parallel to the sliding direction of the adjusting plate 3-3. The adjusting bolt 3-4 is rotatably connected to the frame 1, and the inner end and the threaded hole on the adjusting plate 3-3 form a threaded pair.

[0034] The working principle of the utility model is as follows:

[0035] In the initial state, the door panel 1-3 is in the closed limit position, and together with the end closing plate 1-5 and the two grid side panels 1-2, a storage chamber with an open top is formed. The parcels output from the parcel sorting machine fall into the storage chamber one by one. When the fallen parcels accumulate until they block the light beam emitted by the photoelectric sensor 4-1 to the reflector, a lock grid command is sent to the parcel sorting machine to stop the parcel from falling further. The flip drive motor 2-1 drives the transmission rod 2-2 to rotate through the belt transmission assembly, thereby driving the flip connecting rod 2-3 to move, pushing the door panel 1-3 to flip outward until it reaches the conveying limit position. The parcels stored in the storage chamber are centrally output through the belt conveyor mechanism 3.
