Example two

As shown in fig. 10-17, this embodiment provides another forward sorter that is substantially identical to the apparatus of the first embodiment, except for the tilt reset assembly.

As shown in fig. 10, the tilt reset assembly comprises a support member 6, the support member 6 being rotatably connected to the swivel 2, the support member 6 having a first position and a second position when rotated, the sorting carriage 4 being in a horizontal position when the support member 6 is in the first position; the sorting carriage 4 is in a tipped state when the support assembly 6 is in the second position.

Further, the supporting assembly 6 comprises a deflector rod 61 and a supporting wheel 62, the supporting wheel 62 is mounted on the deflector rod 61, the deflector rod 61 is rotatably arranged on the swivel 2, when the supporting assembly 6 is positioned at the first position, the supporting wheel 62 is in contact with the lower surface of the vehicle body 41, the supporting effect is achieved on the sorting vehicle 4, the sorting vehicle 4 is in a horizontal state, and the objects to be sorted are convenient to convey.

The tipping reset assembly further comprises an unloading mechanism 7, the unloading mechanism 7 being used for driving the deflector rod 61 to rotate. Specifically, the unloading mechanism 7 includes an unloading body 71 and an unloading telescopic end 72, the unloading body 71 is mounted on the frame 1, the unloading telescopic end 72 can drive the shift lever 61 to rotate, and the axis of rotation of the shift lever 61 is along the vertical direction. The unloading mechanism 7 has two states of a tipping position and a normal position, when the unloading mechanism 7 is in the normal position, the unloading telescopic end 72 is retracted, and the unloading mechanism 7 does not influence the rotation of the swivel 2 and the sorting vehicle 4; when the unloading mechanism 7 is in the tipped position, the unloading telescoping end 72 is extended until the unloading telescoping end 72 is in contact with the lever 61. The swivel 2 continues to rotate with the sorting carriage 4, the unloading telescopic end 72 blocks the rotation of the shift lever 61, so that the shift lever 61 rotates around the vertical direction, and the shift lever 61 drives the supporting wheel 62 to rotate, so that the supporting wheel 62 gradually breaks away from the carriage body 41. When the support wheels 62 are completely clear of the body 41, the sorting carriage 4 starts to tip over to complete the unloading of the objects to be sorted.

In particular, the support assembly 6 further comprises a mounting 63, the mounting 63 being fixed to the swivel 2 for rotation with the swivel 2. The mounting frame 63 comprises a mounting column, and the deflector rod 61 is rotatably arranged on the mounting column, so that the swivel 2 can conveniently drive the deflector rod 61 to rotate.

The support assembly 6 further comprises a return member 64, the return member 64 being adapted to return the lever 61, which is driven in rotation by the unloading mechanism 7. In the present embodiment, the return member 64 is a spring, and the lever 61 returns by the elastic force of the spring.

As shown in fig. 11-13, the process of tipping the sorting carriage 4 is as follows:

the unloading mechanism 7 is in the tilt position, in which the unloading telescopic end 72 is in contact with the lever 61. The swivel 2 continues to rotate with the sorting carriage 4, the unloading telescopic end 72 blocks the rotation of the shift lever 61, so that the shift lever 61 rotates around the vertical direction, and the shift lever 61 drives the supporting wheel 62 to rotate, so that the supporting wheel 62 gradually breaks away from the carriage body 41. When the support wheel 62 is completely disengaged from the body 41, the sorting carriage 4 loses the support of the support wheel 62 and starts to rotate anticlockwise about the connecting hinge shaft 431, i.e. the sorting carriage 4 starts to tip over, so as to complete the unloading of the objects to be sorted.

The tipping reset assembly further includes a reset member 8, the reset member 8 being configured to reset the tipped sorting cart 4. Specifically, the restoring member 8 includes a restoring body mounted on the frame 1 and a restoring telescopic end capable of contacting the lower surface of the vehicle body 41.

The swivel 2 carries the sorting carriage 4 to continue to rotate together, the sorting carriage 4 is in a tilting state, and the reset telescopic end hinders the rotation of the sorting carriage 4, so that the sorting carriage 4 rotates clockwise around the connecting hinge shaft 431, that is, the sorting carriage 4 starts to recover to a horizontal state from the tilting state, and the next round of sorting work is facilitated.

As shown in fig. 14 to 17, the resetting process of the sorting carriage 4 is specifically as follows:

the return member 8 is in a return state, the sorting carriage 4 is in a tip-over state, and the return telescopic end starts to contact with the lower surface of the carriage body 41. At this time, the lever 61 is blocked by the side plate 412 of the sorting carriage 4 and cannot return. The swivel 2 continues to rotate with the sorting carriage 4, and the return telescopic end blocks the rotation of the sorting carriage 4, so that the sorting carriage 4 rotates clockwise about the connection hinge 431 until the sorting carriage 4 returns from the tipped state to the horizontal state. The side plate 412 of the sorting vehicle 4 does not block the deflector rod 61 any more, the deflector rod 61 returns under the action of the return piece 64, the supporting wheel 62 contacts with the lower surface of the vehicle body 41, the sorting vehicle 4 has a supporting function, the sorting vehicle 4 can be kept in a horizontal state, and then the next round of sorting work is performed.

In this embodiment, the support assembly 6, the unloading mechanism 7 and the reset member 8 are used to realize the tilting of the sorting carriage 4 and the reset after the tilting, so that the unloading operation can be completed without opening the barrier by an additional mechanism, the structure is simple, the operation is simple and convenient, and the sorting efficiency is improved. The tipping reset assembly drives the sorting carriage 4 to tip towards the pockets in the running direction so that the objects to be sorted slide out of the openings 42 into the respective pockets. The objects to be sorted are unloaded in the forward direction, so that the occupied area of equipment is greatly reduced, and the adaptability is high.

step S2: the sorting vehicle 4 is positioned on the first rail 51, the supporting wheels 62 are in contact with the lower surface of the vehicle body 41, and the sorting vehicle 4 has a supporting function, so that the sorting vehicle 4 is in a horizontal state, and the to-be-sorted objects are placed in the sorting vehicle 4 by manual or automatic object feeding equipment and conveyed along with the rotation of the swivel 2;

step S3: when moving to the site where delivery is required, the unloading mechanism 7 is in the tipping position, and the unloading telescopic end 72 is in contact with the deflector rod 61. The swivel 2 continues to rotate with the sorting carriage 4, the unloading telescopic end 72 blocks the rotation of the shift lever 61, so that the shift lever 61 rotates around the vertical direction, and the shift lever 61 drives the supporting wheel 62 to rotate, so that the supporting wheel 62 gradually breaks away from the carriage body 41. When the supporting wheel 62 is completely separated from the vehicle body 41, the sorting vehicle 4 starts to tilt, and objects to be sorted slide into the grid openings from the openings 42, so that delivery of the objects to be sorted is completed;

step S4: the unloaded sorting carriage 4 is in a tipped state and rotates together with the swivel 2. The return member 8 is in a return state, and the return expansion end starts to contact with the lower surface of the vehicle body 41. At this time, the lever 61 is blocked by the side plate 412 of the sorting carriage 4 and cannot return. The swivel 2 continues to rotate with the sorting carriage 4, and the return telescopic end blocks the rotation of the sorting carriage 4, so that the sorting carriage 4 rotates clockwise about the connection hinge 431 until the sorting carriage 4 returns from the tipped state to the horizontal state. The side plates 412 of the sorting vehicle 4 do not block the deflector rod 61 any more, the deflector rod 61 returns under the action of the return piece 64, the supporting wheels 62 are in contact with the lower surface of the vehicle body 41, the sorting vehicle 4 has a supporting function, the sorting vehicle 4 can keep a horizontal state, and the return action is completed;

step S5: the sorting carriage 4 performs the next round of sorting work.
