Description

Technical Field

[0001] The utility model belongs to the technical field of logistics sorting equipment, and particularly relates to a sorting trolley adapted to an inclined track. Background Art

[0002] The loop cross-belt sorter includes a trolley system and a track system. The trolley system consists of several sorting trolleys connected end to end. The sorting trolleys are connected end to end through rod end spherical plain bearings to form a closed loop. Most loop cross-belt sorters adopt a single-layer structure, which can achieve rapid processing of goods; however, when dealing with multi-scene sorting types, in order to increase the number of bays, the floor area is very large.

[0003] The multi-layer loop cross-belt sorter can make full use of the vertical space to increase the number of bays within a limited floor area and achieve a greater sorting and processing capacity. The patent application with the publication number of CN112499145 A provides a linear cross-belt sorter; it connects multiple layers of tracks into a large three-dimensional loop track structure; however, when the sorting trolley goes uphill or downhill in this three-dimensional loop track structure, it will tilt, thereby bringing the risk of goods falling.

Detailed Embodiments

[0028] The present utility model will be further described below with reference to the accompanying drawings.

[0029] Embodiment 1

[0030] AsFigure 1 As shown in the figure, a sorting trolley adapted to an inclined track includes a vehicle frame 1, a secondary plate 2, a support and guiding roller set 3, an inclination stabilizing assembly 4, and a cargo carrying and output mechanism 5. The cargo carrying and output mechanism 5 is mounted on the vehicle frame 1 through the inclination stabilizing assembly 4.

[0031] In this embodiment, the cargo carrying and output mechanism 5 adopts a conveyor belt structure, making the sorting trolley a cross-belt trolley. Since the conveyor belt structure outputs a conventional structure, the Figure 1 conveyor belt structure in the figure is simplified and replaced by a dashed-line frame.

[0032] The secondary plate 2 is mounted at the bottom of the vehicle frame and is used to cooperate with the linear motor to provide power to the sorting trolley in a non-contact manner. The inclination stabilizing assembly 4 is used to cooperate with an auxiliary track additionally provided on the annular track of the sorter. When the vehicle frame 1 is inclined, the cargo carrying and output mechanism 5 is maintained in a horizontal posture.

[0033] The support and guiding roller set 3 includes two traveling wheels 3-1 and a guiding wheel 3-2; the vehicle frame 1 is in a T shape and includes a longitudinal beam and a cross beam at the tail end; the two coaxial traveling wheels 3-1 are respectively rotatably connected to both sides of the tail end of the vehicle frame 1. The guiding wheel 3-2 with a vertically arranged axis is rotatably connected to the bottom of the tail end of the vehicle frame 1.

[0034] The traveling wheels 3-1 are used to cooperate with the support rail groove in the annular track of the sorter to provide support for the sorting trolley. The guiding wheel 3-2 is used to cooperate with the guiding and limiting surface in the annular track of the sorter to provide guiding for the sorting trolley 3 in the horizontal direction. The support rail groove and the guiding and limiting surface in the annular track are the same as those in the prior art and will not be elaborated here.

[0035] The inclination stabilizing assembly 4 includes a support 4-1, a horizontal beam 4-2, and a horizontal auxiliary wheel 4-3. The bottom end of the support 4-1 is fixed to the front end of the top of the vehicle frame 1; one end of the horizontal beam 4-2 is rotatably connected to the top end of the support 4-1. Both sides of the other end of the horizontal beam 4-2 are rotatably connected with the horizontal auxiliary wheels 4-3.

[0036] As Figure 2 shown, during the working process, the horizontal auxiliary wheels 4-3 are supported in the auxiliary rail groove above the annular track of the sorter; both ends of the horizontal beam 4-2 are supported by the support 4-1 and the horizontal auxiliary wheels 4-3 (specifically, a support structure based on a hinge support); by adjusting the position and shape of the auxiliary rail groove, the relative position between the rotation axis between the horizontal beam 4-2 and the support 4-1 and the rotation center of the horizontal auxiliary wheels 4-3 can be kept unchanged, so that the posture of the horizontal beam 4-2 remains unchanged during the entire uphill or downhill process of the sorting trolley; ensuring the horizontal posture of the cargo carrying and output mechanism 5 during the uphill and downhill processes.

[0037] Among two adjacent sorting carts, the tail end of the frame 1 of the previous sorting cart and the head end of the frame 1 of the subsequent sorting cart form a spherical pair through a spherical eye bearing.

[0038] The rotation center of the spherical pair between the frames 1 of two adjacent sorting carts is on the rotation axis of the traveling wheels 3-1 of the previous sorting cart; thus, relative rotation can occur at the change of the climbing inclination angle of the two sorting carts, and the distance between the axes of the traveling wheels in two adjacent sorting carts will not change, so as to achieve the effect that each sorting cart approximately has two sets of front and rear traveling wheels; it can avoid the change of the inclination angle of the frame caused by the change of the distance between the axes of the traveling wheels, and ensure that the cargo carrying and output mechanism 5 on the horizontal beam 4-2 can be stable in a horizontal posture.

[0039] The working principle of the present utility model is as follows:

[0040] Multiple connected sorting carts circulate in a three-dimensional annular track with an uphill and downhill structure, and the received goods are sent to the specified sorting compartments. During the uphill and downhill process, the horizontal auxiliary wheels 4-3 are used in cooperation with the auxiliary track added above the sorting machine annular track to keep the horizontal posture of the cargo carrying and output mechanism 5, and avoid the goods from falling due to the inclination of the cargo carrying and output mechanism 5.

[0041] Embodiment 2

[0042] As Figure 3 shown, a sorting cart adapted to an inclined track. The difference between this embodiment and Embodiment 1 lies in: the structure of the cargo carrying and output mechanism 5 is different. The cargo carrying and output mechanism 5 adopts a passive turnover structure, which includes a turnover mechanism 8 and a tray 9. The turnover mechanism 8 is installed on the horizontal beam 4-2 of the inclination stabilizing assembly 4. The tray 9 is installed on the turnover mechanism 8.

[0043] The turnover mechanism 8 is used to support the tray 9 and is unlocked passively under the drive of the lower package assembly in the sorting machine, so that the tray 9 turns over to complete the lower package.

[0044] As Figure 4 and Figure 5 shown, the turnover mechanism 8 includes a support base 8-1, a locking rod 8-2, a turning base 8-3, a limit locking member 8-4, a return spring, a trigger member 8-5 and a limit buffer structure 8-6. The support base 8-1 includes two vertical plates arranged at intervals. The bottom ends of the two vertical plates are both fixed to the horizontal beam 4-2. The two vertical plates are arranged at intervals along the traveling direction of the sorting cart. The two ends of the locking rod 8-2 are respectively fixed to the two vertical plates.

[0045] Two flipping rods 8-3-1 are fixedly arranged at intervals at the bottom of the flipping base 8-3. The bottom ends of the two flipping rods 8-3-1 of the flipping base 8-3 and the top ends of two vertical plates respectively form coaxial first rotating pairs through hinge shafts. The common axis of the first rotating pairs is parallel to the arrangement direction of the two vertical plates.

[0046] The trigger member 8-5 and the bottom of the rear end of the flipping base 8-3 form a second rotating pair. The axis of rotation of the second rotating pair is perpendicular to the axis of rotation of the first rotating pair. Two inclined trigger plates are arranged on the trigger member 8-5 and are respectively located on both sides of the support base 8-1. In the initial state, along the traveling direction of the sorting trolley, the bottom surface of the inclined trigger plate gradually rises; the two inclined trigger plates are used to cooperate with the lower package trigger components installed on the inner and outer sides of the sorting machine track to unlock the flipping base 8-3 and the tray 9.

[0047] The limit locking member 8-4 is fixed on the lower surface of the trigger member 8-5 and is located directly above the locking rod 8-2. A limit groove 8-4-1 is opened at the bottom of the limit locking member 8-4. The two ends of the limit groove 8-4-1 are respectively located on the two side surfaces of the limit locking member 8-4. In the initial state, the limit groove 8-4-1 is clamped with the locking rod 8-2 to lock the position of the flipping base 8-3. When the limit locking member 8-4 rotates upward with the trigger member 8-5, the limit groove 8-4-1 is disengaged from the locking rod 8-2. The two ends of the return spring are respectively fixed to the trigger member 8-5 and the flipping base 8-3. The return spring is used to provide elastic force for the rotating transmission plate member, thereby driving the limit locking member 8-4 to have a tendency to rotate downward, so that the limit locking member 8-4 abuts against the locking rod 8-2.

[0048] The limit buffer structure 8-6 is installed at the top of the vertical plate near the front end of the sorting trolley. The limit buffer structure 8-6 includes two limit plates 8-6-1. The two limit plates 8-6-1 are respectively fixed at the tops of both sides of the vertical plate. Two limit surfaces are arranged at the tops of the adjacent sides of the two limit plates 8-6-1; the two limit surfaces are arranged in a V shape. The limit surfaces respectively provide limits for the flipping of the flipping base 8-3 to both sides. The distances from the two limit surfaces to the axis of rotation of the flipping base 8-3 are equal to the distances from the side surface of the flipping rod 8-3-1 to the axis of rotation of the flipping base 8-3, thereby ensuring that the flipping rod 8-3-1 and the limit surface can be in surface contact and improving the support stability of the limit surface for the flipping rod 8-3-1.

[0049] As Figure 3 shown, the limit groove 4-1 divides the bottom surface of the limit locking member 7 into two symmetrically arranged guiding parts 4-2.

[0050] The double-sided turnover trolley has three working states, namely the locked state, the inner unlocking state, and the outer unlocking state. When the limit locking member 7 is in the locked state, the locking rod 5 is clamped in the limit groove 4-1; the top surface of the flipping base 6 is in a horizontal state.

[0051] When the limit locking member 7 is in the inner unlocking state or the outer unlocking state, the limit groove 4-1 is separated from the locking rod 5, the locking of the limit locking member 7 to the turning base 6 is released, and the turning base 6 turns to the inner side or the outer side to the extreme state. The turning rod 6-1 at the front end of the turning base 6 contacts the inner or outer limit pad 8-2. The locking rod 5 contacts the middle part of the corresponding guiding part 4-2 on the limit locking member 7.

[0052] During the conversion of the double-sided turnover trolley from the inner unlocking state or the outer unlocking state to the locking state, the locking rod 5 can be re-inserted into the limit groove 4-1.

[0053] In some embodiments, rounded corners are provided at both side edges of the notch of the limit groove 4-1.
