Description

Technical Field

[0001] The utility model belongs to the technical field of logistics sorting equipment, and particularly relates to a sorting machine double-sided turnover trolley and a double-sided turnover sorting machine. Background Technique

[0002] In modern logistics and automated production lines, a sorting machine is a crucial piece of equipment used to automatically separate and convey items according to a predetermined classification method. Among them, the double-sided turnover trolley and its sorting machine are widely used in multiple fields such as postal parcels, express logistics, and warehouse management because they can perform sorting operations from both sides simultaneously, greatly improving the sorting efficiency and flexibility. However, there are some technical problems and limitations in the design of existing double-sided turnover trolleys and sorting machines: Since the tray needs to be flipped to both sides, it is difficult to achieve under-package control through the under-package triggering structure installed on the track. For example, in the patent application with the publication number CN221092289U, the tray flipping control of the sorting trolley is achieved by installing a motor and a transmission system on the sorting trolley, but this method greatly increases the equipment cost.

[0003] In addition, sorting compartments are installed on both sides of the double-sided turnover sorting machine; this results in the fact that the size of the under-package triggering structure along the width direction of the track cannot be too large, otherwise, it will cause the situation that the under-package triggering structure blocks the package from entering the sorting compartment.

[0027] The present utility model will be further described below with reference to the accompanying drawings.

[0028] In the following embodiments, the rear end refers to the end departing from the traveling direction of the bilateral turnover trolley.

[0029] As Figure 1 and 2 shown, a bilateral turnover trolley of a sorting machine includes a vehicle frame 1, a guiding and supporting wheel set 2, a bilateral flipping structure, a bilateral limiting and buffering structure 8 and a tray 3. The guiding and supporting wheel set 2 is installed at the bottom of the vehicle frame 1 and is used to realize the guiding and supporting of the bilateral turnover trolley on the annular track 11. The guiding and supporting wheel set 2 includes a guiding wheel with a vertically arranged axis and a supporting wheel with a horizontally arranged axis. The tray 3 is connected to the vehicle frame 1 through the bilateral flipping structure.

[0030] The bilateral flipping structure can lock the tray 3 in a horizontal state and can flip to either side after unlocking. The tray 3 has a symmetric structure with a concave middle part and raised left and right sides. The front and rear sides of the tray 3 are provided with upwardly folded edges to prevent the goods from falling off the tray 3.

[0031] The bilateral flipping structure includes a supporting base 4, a locking rod 5, a flipping base 6, a limiting and locking member 7, a reset spring and a triggering member 9. The supporting base 4 includes two spaced-apart support plates. The bottom ends of the two support plates are both fixed to the vehicle frame 1 (integrally formed in this embodiment). The two support plates are spaced apart along the traveling direction of the bilateral turnover trolley. The two ends of the locking rod 5 are respectively fixed to the two support plates.

[0032] Two spaced-apart flipping rods 6-1 are fixed to the bottom of the flipping base 6. The bottom ends of the two flipping rods 6-1 of the flipping base 6 and the top ends of the two support plates are respectively formed into coaxial first rotating pairs through hinge shafts. The common axis of the first rotating pairs is parallel to the arrangement direction of the two support plates.

[0033] The trigger member 9 and the bottom of the rear end of the flipping base 6 form a second rotating pair. The rotation axis of the second rotating pair is perpendicular to the rotation axis of the first rotating pair. The trigger member 9 is provided with two inclined trigger plates respectively located on both sides of the support base 4. In the initial state, along the traveling direction of the double-sided turnover 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 structures 14 installed on the inner and outer sides of the sorting machine track to unlock the flipping base 6 and the tray 3.

[0034] The limit locking member 7 is fixed on the lower surface of the trigger member 9 and is located directly above the locking rod 5. A limit groove 7-1 is opened at the bottom of the limit locking member 7. The two ends of the limit groove 7-1 are respectively located on the two side surfaces of the limit locking member 7. In the initial state, the limit groove 7-1 is clamped with the locking rod 5 to lock the position of the flipping base 6. When the limit locking member 7 flips upward along with the trigger member 9, the limit groove 7-1 is disengaged from the locking rod 5. The two ends of the return spring are respectively fixed to the trigger member 9 and the flipping base 6. The return spring is used to provide elastic force for the rotating transmission plate member, so as to drive the limit locking member 7 to have a downward flipping trend, so that the limit locking member 7 abuts against the locking rod 5.

[0035] As Figure 3 shown, the limit groove 7-1 divides the bottom surface of the limit locking member 7 into two symmetrically arranged guiding portions 7-2. The guiding portion 7-2 includes a guiding section 7-2-1, an unlocking stable section 7-2-2 and an extending section 7-2-3 that are connected in sequence along the direction away from the limit groove 7-1. The unlocking stable section 7-2-2 is connected to the notch edge of the limit groove 7-1 through an arc-shaped guiding section 7-2-1. Along the direction away from the limit groove 7-1, the distance from the guiding section 7-2-1 to the axis of the first rotating pair gradually decreases, and the distance from the extending section 7-2-3 to the axis of the first rotating pair gradually increases. The distance between the unlocking stable section 7-2-2 and the axis of the first rotating pair is equal to the distance between the bottom of the limit groove 7-1 and the axis of the first rotating pair; thus, when the limit locking member 7 is in the inner unlocking position or the outer unlocking position, the unlocking stable section 7-2-2 of the guiding portion 7-2 is supported on the locking rod 5 and remains stable.

[0036] The bilateral limit buffer structure 8 is installed on the top of the support plate near the front end of the bilateral turnover trolley. The bilateral limit buffer structure 8 includes two connecting plates 8-1 and two limit pads 8-2. The two connecting plates 8-1 are respectively fixed on the tops of both sides of the support plate. The two limit pads 8-2 are respectively fixed on the tops of the adjacent sides of the two connecting plates 8-1. The two limit pads 8-2 are respectively located on both sides of the turning rod 6-1 at the front end of the turning base 6, and the adjacent side surfaces are arranged in a V shape. The limit pads 8-2 respectively provide limits for the turning of the turning base 6 to both sides. The distances from the two limit pads 8-2 to the rotation axis of the turning base 6 are equal to the distances from the side surface of the turning rod 6-1 to the rotation axis of the turning base 6, thereby ensuring that the turning rod 6-1 and the limit pads 8-2 can be in surface contact and improving the support stability of the limit pads 8-2 for the turning rod 6-1.

[0037] The bilateral turnover trolley has three working states, namely the locked state, the inner unlocked state, and the outer unlocked state. When the limit locking member 7 is in the locked state, the locking rod 5 is clamped in the limit groove 7-1; the top surface of the turning base 6 is in a horizontal state.

[0038] When the limit locking member 7 is in the inner unlocked state or the outer unlocked state, the limit groove 7-1 is separated from the locking rod 5, the locking of the limit locking member 7 on the turning base 6 is released, and the turning base 6 turns to the extreme state inward or outward. 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 unlocking stable section 7-2-2 of the corresponding guiding portion 7-2 on the limit locking member 7.

[0039] During the conversion of the bilateral turnover trolley from the inner unlocked state or the outer unlocked state to the locked state, the locking rod 5 can be reinserted into the limit groove 7-1.

[0040] In some embodiments, rounded corners are provided at both side edges of the notch of the limit groove 7-1.

[0041] Embodiment 2

[0042] Such as Figure 4 And 5As shown in the figure, a double-sided turnover sorting machine includes a frame 10, a circular track 11, a reset rod 12, a plurality of sorting bays 13 arranged on the inner and outer sides of the circular track 11, a lower package triggering structure 14, and a plurality of double-sided turnover trolleys as described in the embodiments connected in sequence on the circular track 11. The circular track 11 is installed on the frame 10. The lower package triggering structures 14 installed on both sides of the circular track 11 are respectively used to cooperate with the inclined triggering plates on both sides of the trigger member 9 to realize the output of the packages on the tray 3. Each sorting bay 13 corresponds to each lower package triggering structure 14 one by one. The corresponding sorting bay 13 and the lower package triggering structure 14 are respectively arranged on the opposite sides of the circular track 11. Two reset rods 12 are respectively installed on the inner and outer sides of the circular track 11, and are respectively used to guide the double-sided turnover trolleys in the inner unlocking state and the outer unlocking state back to the locked state.

[0043] In this embodiment, reset supporting parts are provided on both sides of the bottom surface of the tray 3; the reset supporting parts are used to cooperate with the corresponding reset rods 12, so that the reset rods 12 can push the inclined tray 3 to turn upward and reset. In some embodiments, elastic pads are provided on the reset supporting parts to reduce the friction noise between the reset supporting parts and the reset rods 12.

[0044] As Figure 6 shown in the figure, the lower package triggering structure 14 includes a lower package bracket 14-1, a cylinder 14-2, a lever 14-3 and a lower package roller 14-4. The lower package bracket 14-1 is fixed on the side of the circular track 11. The cylinder end of the cylinder 14-2 is rotatably connected to the lower package bracket 14-1. The lever 14-3 is provided with a turning fulcrum. The turning fulcrum of the lever 14-3 is rotatably connected to the lower package bracket 14-1. One end of the lever 14-3 is rotatably connected to the outer end of the piston rod of the cylinder 14-2. The outer end of the lever 14-3 is rotatably connected with a lower package roller 14-4. The expansion and contraction of the cylinder 14-2 can drive the lever 14-3 to turn around the turning fulcrum. The axis of rotation of the lever 14-3 around the turning fulcrum is perpendicular to the traveling direction of the double-sided turnover trolley.

[0045] Driven by the cylinder 14-2, the lower package triggering structure 14 has two working states, namely the triggering state and the standby state. When the cylinder 14-2 retracts, the lower package triggering structure 14 is in the standby state, and the outer end of the lever 14-3 turns to the lower limit position. At this time, the lower package roller 14-4 is located below the moving path of the inclined triggering plate on the corresponding side of the double-sided turnover trolley and will not have any impact on the passing double-sided turnover trolley.

[0046] When the cylinder 14-2 extends, the lower package triggering structure 14 is in the triggering state. The outer end of the lever 14-3 flips to the upper limit position, causing the lower package roller 14-4 to be on the moving path of the inclined triggering plate on the corresponding side of the double-sided turnover trolley. At this time, the lower package roller 14-4 can push the inclined triggering plate of the passing double-sided turnover trolley to flip upward, unlocking the tray 3 of the double-sided turnover trolley, and causing the tray 3 to flip to the side away from the lower package roller 14-4 under the push of the lower package roller 14-4.

[0047] In this embodiment, the lower package triggering structure 14 uses the up-and-down flipping of the lever 14-3 to switch states, so that the long side of the lower package triggering structure 14 is arranged along the length direction of the annular track 11, which helps to reduce the space occupied in the width direction of the annular track 11 and avoid the lower package triggering structure 14 occupying the installation space of the sorting grid 13 on the same side, resulting in the situation where the lower package triggering structure 14 blocks the goods from falling into the sorting grid 13.

[0048] In some embodiments, the lower package triggering structures 14 on both sides of the annular track 11 are installed in an inclined shape like an eight-character, specifically, the tops of the two lower package triggering structures 14 are close to each other, and the bottoms are far from each other; thus, when the lower package roller 14-4 flips upward with the lever 14-3, it can move upward and horizontally inward; without increasing the width of the triggering member 9, the lower package roller 14-4 can smoothly reach directly below the inclined triggering plate of the triggering member 9.

[0049] The working principle of this embodiment is as follows:

[0050] Place the goods on the tray 3 of one of the double-sided turnover trolleys on the upper package section of the annular track 11. Transport the logistics goods to the target sorting grid 13 through the double-sided turnover trolley. When approaching the target sorting grid 13, the cylinder 14-2 in the lower package triggering structure 14 corresponding to the target sorting grid 13 extends, driving the lower package roller 14-4 to flip upward with the lever 14-3. During the process of the inclined triggering plate of the double-sided turnover trolley passing through the position where the lower package roller 14-4 is located, it drives the tray 3 to flip, causing the goods placed on the tray 3 to fall to the target sorting grid 13 and slide down, realizing the output of the package.
