Description

Technical Field

[0001] The present invention relates to the technical field of logistics sorting equipment, and in particular to a sorting trolley based on monorail power supply. Background Art

[0002] At present, the existing track-powered sorting trolleys usually rely on brushes set at the bottom of the trolley to draw power from the power supply track. The conductive rails of the power supply track are composed of multiple parallel conductive rails. Brushes corresponding to each conductive rail are set at the bottom of the trolley. The running wheels on both sides of the trolley are set on both sides of the trolley to clamp the trolley on the power supply track.

[0003] Since the trolley is wrapped around the power rail, the size of the trolley is relatively large, and due to the size of the trolley, the curvature of the power rail cannot be too small, otherwise the trolley will easily get stuck when turning. Therefore, the sorting system composed of the existing sorting trolleys needs to occupy a large area, making the entire sorting system too large. Summary of the invention

[0008] The guide mechanism includes a flange sleeve fixed on the chassis, the flange sleeve extends into the U-shaped groove of the power supply guide rail, and is sleeved with a plurality of guide wheels and two conductive brush heads arranged back to back, the conductive ends of the conductive brush heads extend into the conductive rails arranged on the groove walls on both sides of the power supply guide rail, and are in sliding electrical contact with the conductive rails.

[0009] Optionally, the guide mechanism is provided with a lifting mechanism, and the lifting mechanism comprises a telescopic shaft, a top plate and an electromagnet;

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Please refer to the instruction manual Figure 6 In an embodiment of the present invention, a sorting trolley based on monorail power supply is proposed, which is applied to a U-shaped power supply rail 2.

[0028] like Figure 5 As shown, the power supply guide rail includes a groove-type guide rail 21, and the center of the upper end bearing surface of the groove-type guide rail 21 has a U-shaped groove 2a, and the U-shaped groove 2a divides the upper end bearing surface of the groove-type rail into two. Conductive rails 22 are respectively provided on the groove walls on both sides of the U-shaped groove 2a to supply power to the sorting trolley used on the power supply guide rail 2.

[0029] like Figure 1As shown, the sorting trolley 1 includes a frame body 111, and a small conveyor belt device 12 is provided on the upper side of the frame body 111. The small conveyor belt device 12 includes an active roller 121 and a passive roller 122. The active roller 121 and the passive roller 122 are connected through a synchronous belt (not shown).

[0030] A chassis 112 is provided at the bottom center area of ​​the frame body 111, and a driving device 12 is provided on the chassis 112 to drive the sorting trolley to run on the power supply rail 2. The driving device slot 3 includes a main driving mechanism 131 and a slave driving mechanism 132, and the main driving mechanism 131 and the slave driving mechanism 132 are respectively provided with a guide mechanism 14 vertically arranged below the chassis 112.

[0031] Specifically, Figure 3 As shown, the main driving mechanism 131 includes a first bearing seat 1311, a second bearing seat 1312 and a third bearing seat 1313, which are arranged in sequence, a transmission shaft 1318 and a driving motor 1319. A first rotating shaft 1314 is provided between the first bearing seat 1311 and the second bearing seat 1312, a second rotating shaft 1315 is provided between the second bearing seat 1312 and the third bearing seat 1313, the first rotating shaft 1314 and the second rotating shaft 1315 are coaxially arranged, and active walking wheels (1316, 1317) are provided on the first rotating shaft 1314 and the second rotating shaft 1315, respectively.

[0032] One end of the first rotating shaft 1314 close to the first bearing seat 1311 extends outward and is provided with a first gear 13141. One end of the second rotating shaft 1315 close to the third bearing seat 1313 extends outward and is provided with a second gear 13151. The transmission shaft 1318 is parallel to the first rotating shaft 1314 and the second rotating shaft 1315, and third gears (13181, 13812) are respectively provided at both ends of the transmission shaft 1318. The first gear 13141 and the second gear 13151 are respectively meshed with the third gears (13181, 13812) at both ends of the transmission shaft 1318 for transmission.

[0033] The driving motor 1319 is fixed on the chassis 112 , and its output shaft is parallel to the transmission shaft 1318 . An output tooth 13191 is provided on the output shaft, and the output tooth 13191 meshes with a third gear 13181 at one end of the transmission shaft 1318 for transmission.

[0034] like Figure 2As shown, the slave drive mechanism 132 includes a fourth bearing seat 1321, a fifth bearing seat 1322 and a sixth bearing seat 1323 which are arranged in sequence. A third rotating shaft 1324 is provided between the fourth bearing seat 1321 and the fifth bearing seat 1322, and a fourth rotating shaft 1325 is provided between the fifth bearing seat 1322 and the sixth bearing seat 1323. The third rotating shaft 1324 and the fourth rotating shaft 1325 are respectively provided with driven running wheels (1326, 1327), and the two driven running wheels (1326, 1327) correspond to the two active running wheels (1316, 1317) one by one and are in the same straight line. Thus, the running wheels on both sides of the main drive mechanism 131 and the slave drive mechanism 132 can be arranged on the bearing surfaces on both sides of the U-shaped groove 2a of the power supply guide rail 2.

[0035] like Figure 4 As shown, the guide mechanism 14 includes a flange sleeve 141 fixed to the chassis 112, the flange sleeve 141 extends into the U-shaped groove 2a of the power supply rail 2, and is sleeved with a plurality of guide wheels 142 and two conductive brush heads 143 arranged opposite to each other, and the conductive ends of the conductive brush heads 143 extend into the conductive rails 22 arranged on the groove walls on both sides of the power supply rail 2, and are in sliding electrical contact with the conductive rails 22. Thus, it is possible to draw power from the two conductive rails 22 in the power supply rail 2 through the conductive brush heads 143 arranged on the flange sleeve 141, and supply power to the driving motor 1319 that drives the small conveyor belt device 12 and the main driving mechanism 131. At the same time, the guide wheels 142 sleeved on the flange sleeve 141 can also provide guiding support for the steering of the sorting trolley 1 on the power supply rail 2.

[0036] By arranging the conductive brush head 143 and the guide wheel 142 for collecting electricity on the flange sleeve 141, the guide mechanism 14 can play both a guiding role and a power collection role, and is arranged in the center of the frame body 111, which facilitates the miniaturization of the overall sorting trolley 1.

[0037] By respectively arranging guide mechanisms 14 on the main drive mechanism 131 and the slave drive mechanism 132, it is possible to provide a good guiding effect for the operation of the sorting trolley 1 on the conductive guide rail, and the two guide mechanisms 14 can also independently draw power from the power supply rail 2 to achieve a dual power supply effect, thereby ensuring the stability of the sorting trolley 1 drawing power from the power supply rail 2.

[0038] The present invention arranges a chassis 112 at the bottom center of the frame body 111, and arranges a main drive mechanism 131 and a slave drive mechanism 132 on the chassis 112, so that the driving part of the sorting trolley 1 is concentrated in the bottom center area of ​​the frame body 111, so as to miniaturize the sorting trolley 1 so that it can be used on the U-shaped power supply rail 2.

[0039] Accordingly, a guide mechanism 14 is provided on the main drive mechanism 131 and the slave drive mechanism 132 to provide guide support for the turning and shape of the sorting trolley 1 on the power supply rail. Since the guide mechanism 14 is concentrated in the central area of ​​the chassis 112, the volume of the sorting trolley 1 will not be increased, so that the sorting trolley 1 can be miniaturized as a whole.

[0040] Moreover, each traveling wheel in the main driving mechanism 131 and the slave driving mechanism 132 adopts independent rotation as support, so as to facilitate setting the guide mechanism 14 at the center position of the main driving mechanism 131 and the slave driving mechanism 132, which can provide convenience for the setting of the guide mechanism 14.

[0041] like Figure 8 As shown, when the power supply rails 2 intersect, the U-shaped grooves 2a of the two power supply rails 2 will form a connection area at the intersection. When a single guide mechanism 14 is used, if the guide mechanism 14 enters the connection area, it is easy to cause the sorting trolley 1 to deviate. By adopting two guide mechanisms 14, when one of the guide mechanisms 14 enters the connection area, the other mechanism can be used for guidance to ensure the stability of the sorting trolley 1 along the power supply rail 2. At the same time, the two independent power supply structures formed by the conductive brush heads arranged on the two guide mechanisms 14 can also be used to supply power to the sorting trolley 1 by the conductive brush head on the other guide mechanism 14 when one of the guide mechanisms 14 enters the connection area and the power is cut off, thereby ensuring the power supply stability of the sorting trolley 1 at the intersection of the power supply rails 2, so as to avoid power outages at the intersection of the power supply rails 2.

[0042] Alternatively, if Figure 1 , 4, 6 and 7, in this embodiment, the guide mechanism 14 is provided with a lifting mechanism 15, and the lifting mechanism 15 includes a telescopic shaft 151, a top plate 152 and an electromagnet 153. The telescopic shaft 151 is slidably inserted in the flange sleeve 141, and a guide groove 2b is recessed at the bottom of the U-shaped groove 2a of the power supply guide rail 2. The lower end of the telescopic shaft 151 extends into the guide groove 2b, and its upper end passes through the chassis 112 and the second bearing seat 1312 (or the fifth bearing seat 1322) and extends into the frame body 111. The second bearing seat 1312 and the fifth bearing seat 1322 are respectively provided with through holes (1312a, 1322a) for the corresponding telescopic shaft 151 to pass through. The top plate 152 is vertically arranged at the upper end of the telescopic shaft 151, and the electromagnet 153 is located below the top plate 152 and fixed on the frame body 111. There is a spring (not shown) between the electromagnet 153 and the top plate 152. When the electromagnet 153 is energized, it can absorb the top plate 152 so that the top plate 152 moves downward and drives the lower end of the telescopic shaft 151 to extend downward and insert into the guide groove 2b of the power supply guide rail 2; when the electromagnet 153 is de-energized, the top plate 152 will move upward under the action of the elastic restoring force of the spring, causing the telescopic shaft 151 to retract upward, so that the lower end of the telescopic shaft 151 is pulled out of the guide groove 2b of the power supply guide rail 2.

[0043] Accordingly, if Figure 8 As shown, in the connection area of ​​the power supply rail 2, a stopper 3 is provided at the entrance of the branch rail connected to the original power supply rail 2.

[0044] Therefore, when the sorting trolley 1 runs to the intersection and convergence position of the power supply rail 2, the telescopic shaft 151 can be controlled by the electromagnet 153 to achieve the purpose of changing the rail. Specifically, when it is not necessary to change lanes, the power supply of the electromagnet 153 is disconnected, and the telescopic shaft 151 will always remain in a state of being separated from the guide groove 2b of the power supply rail 2 under the action of the spring, and it can move forward along the original power supply rail 2; when it is necessary to change the rails, the power supply of the electromagnet 153 is turned on, and the telescopic shaft 151 is controlled to extend downward and insert into the guide groove 2b of the power supply rail 2. When the lower end of the telescopic shaft 151 contacts and collides with the block 3, the sorting trolley 1 will deviate into the power supply rail 2 where the block 3 is not set under the action of inertia, thereby completing the forced lane change of the sorting trolley 1.

[0045] By setting up the lifting mechanism 15, the sorting trolley 1 can also be used on the crossed power supply rails 2, and realize lane changing on the crossed power supply rails 2, and the structure is simple. There is no need to set up a track changing mechanism on the power supply rails to realize lane changing. It is only necessary to set a block 3 in the guide groove 2b of the power supply rail 2, which facilitates the simplification of the structure of the power supply rail 2.

[0046] Alternatively, if Figure 5As shown, in this embodiment, the groove walls on both sides of the U-shaped groove 2a of the power supply rail 2 are respectively provided with accommodating grooves 21c, and the conductive rail 22 is arranged in the accommodating grooves 21c. By providing the accommodating grooves 21c on the groove walls on both sides of the U-shaped groove 2a to accommodate the conductive rail 22, the conductive rail 22 is prevented from being directly exposed to the outside, thereby reducing the potential safety hazard of the power supply rail 2.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to be construed as limiting the present invention. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present invention should be included in the protection scope of the technical solution of the present invention.
