Embodiment of the sorting carriage

As shown in fig. 1 to 4 and fig. 9, in the present embodiment, the sorting cart 13 of the present invention is provided on the frame of the sorting machine for conveying and sorting packages. The sorting trolley 13 comprises: a vehicle body 131, a sorting conveyance mechanism 132, and a control mechanism. The sorting conveyance mechanism 132 is provided to the vehicle body 131. The control mechanism includes a controller 21 and a data acquisition module. The controller 21 is electrically connected to the sorting conveying mechanism 132, and is configured to control the sorting conveying mechanism 132 to convey the package 4. The data acquisition module is electrically connected to the controller 21, and is configured to acquire first position information of the parcel 4 at the initial position and send the first position information to the controller 21, and the controller 21 is configured to control the sorting and conveying mechanism 1 to adjust the parcel 4 according to the first position information.

The initial position is a position where the parcel 4 is placed on the sorting trolley 13 and is not yet conveyed, or is placed on another mechanism capable of conveying the parcel to the sorting trolley 13, such as the parcel feeding rack 31.

Through the design, the sorting trolley 13 provided by the invention is provided with the controller 21, and the controller 21 can independently control the sorting conveying mechanism 132 of each sorting trolley 13 to transport the packages 4, so that the adjustment of the sorting trolley 13 to the positions of the packages 4 is accurately controlled, meanwhile, the mechanical adjustment is avoided, the noise is reduced, and the running speed of the belt of the sorting trolley is improved.

As shown in fig. 5, in the present embodiment, the sorting conveying mechanism 132 of the sorting cart 13 includes a driving roller 1321, a tension roller 1322, and a belt 1323. The driving roller 1321 is provided on the vehicle body 131, and is connected to the controller 21, and the controller 21 controls the driving roller 1321. Specifically, the start and stop, the rotation speed, and the rotation direction of the driving roller 1321 may be controlled. The tension roller 1322 is provided on the vehicle body 131, and is spaced apart from the driving roller 1321. A belt 1323 is wound around the drive roller 1321 and the tension roller 1322 for carrying the package 4. When the package 4 is transported to the drop-out bay, the controller 21 controls the drive roller 1321 to be activated and the belt 1323 to move to drop the package 4 out of the drop-out bay. Further, the direction in which packages 4 are conveyed along sorter frame 11 is defined as a first horizontal direction F1, the direction in which packages 4 are tossed is defined as a second horizontal direction F2, and second horizontal direction F2 is perpendicular to first horizontal direction F1. In addition, the controller 21 in the present invention is electrically connected to the sorting and conveying mechanism 131, and may be in a wired connection, such as through a USB interface, or in a wireless connection, such as through bluetooth or NFC (near field communication), infrared, and the like, as long as the signal transmission between the controller 21 and the sorting and conveying mechanism can be realized, which is not limited herein.

Further, as shown in fig. 1 and 5 to 8, in the present embodiment, the data acquisition module includes a position sensor 222 electrically connected to the controller 21, and the position sensor 222 is configured to detect first position information of the package 4 at the initial position. Wherein the controller 21 independently controls the sorting conveyor 132 of each cart 13 to adjust the position of the parcel 4 based on the first position information of the parcel 4.

Specifically, in the present embodiment, the position sensor 222 can read the first position information of the package 4. The first position information is a position parameter when the parcel has not been transported, and may include a size of the parcel 4, a size offset from a center line of the cart 13 in the first horizontal direction F1 (i.e., the parcel is in a skewed state), and the like. The position sensor 222 sends the first position information to the controller 21, and the controller 21 independently controls the movement of the sorting conveyor 132 carrying the packages 4 in the second horizontal direction F2 according to the first position information. As shown in fig. 8, the controller 21 controls the actuation of the drive rollers 1321 of the respective sorting carriages 13 according to the first position information and adjusts the rotation speed, the rotation direction and the displacement of the movement of the conveyor belt in the second horizontal direction F2 of the respective drive rollers 1321 to move the parcel 4 to the intermediate position of the carriage 13, i.e. the centre line of the parcel 4 coincides with the centre line of the carriage 13 in the first horizontal direction F1.

Further, in the present embodiment, the data acquisition module further includes a detection sensor (not shown in the figure) configured to detect second position information of the parcel 4 at the adjustment position, where the parcel 4 is transported to the adjustment position after being adjusted at the initial position, and the position adjustment is performed again. The controller 21 is electrically connected to the detection sensor and controls the sorting conveyor 132 according to the second position information of the package 4 to assist in adjusting the position of the package 4. The detecting sensor is used for collecting the position parameters of the adjusted parcel again, and sending the second position information to the controller 21, and if the controller 21 judges that the parcel 4 is still in a skew state, the corresponding driving roller 1321 is further adjusted to adjust the parcel 4 to the middle position of the belt 1323. If the parcel is still in a skew state after readjustment, the parcel can be manually corrected or thrown in advance or in a delayed mode.

The adjusted position is a position where the parcel 4 is transported for a certain time from the initial position. The certain time is not a specific value, and can be adjusted according to actual conditions.

For example, in one embodiment, the position sensor 222 may be disposed on the bag supply rack 31 of the sorting machine, the package 4 is first placed on the bag supply belt 32 (initial position), and the position sensor 222 collects the position parameter (first position information) of the package 4 and transmits the position parameter to the controller 21. The plurality of sorting carts 13 located on the sorter frame 11 may be divided into a conditioning zone and a transport zone along a first horizontal direction F1. The packs 4 are transported via the supply belts 32 to the adjustment zone (adjustment position) and the controller 21 controls the motorized rollers of the respective sorting carriages 13 to adjust the position of the packs 4 in the adjustment zone. Thereafter, the detection sensor detects the adjusted position parameter (second position information) of the package 4, and if the adjusted position parameter meets the requirement for the package 4 to be aligned, the controller 21 controls the transport mechanism 1 to transport the package 4 to the transportation area. If the adjusted position parameter does not meet the parcel-setting requirement, the controller 21 controls the motorized pulley to adjust the position of the parcel 4 again according to the adjusted position parameter (second position information). In the present embodiment, the detection sensor may be a detection camera, which is disposed directly above the adjustment area, photographs the parcel 4, and sends the image information to the controller 21. Alternatively, the detection sensor may be an encoder provided on each sorting trolley 13 for detecting a position parameter of the packages on the sorting trolley 13 and sending the position parameter to the controller 21. Therefore, the sorting trolley 13 can automatically adjust the placing position of the packages, so that the throwing is more accurate, and the labor amount is saved.

Further, referring to fig. 1, in the present embodiment, the control mechanism further includes an external antenna 228. The external antenna 228 is electrically connected to the controller 21 for transmitting signals between the controller 21 and the data acquisition module.

Further, referring to fig. 1, in the present embodiment, the control mechanism further includes a trolley wire 226, which is disposed on one side of the rack 11, which may be the side opposite to the external antenna 228, and is connected to the power source, and configured to provide power to the sorting and conveying mechanism 132 and the control mechanism. Referring to fig. 5, the bottom of the sorting cart 13 is provided with a power extractor 227, which is in contact with the trolley line 226 to extract power from the trolley line 226, and transmit the power to the sorting and conveying mechanism 132 and the control mechanism. Of course, power lines can be provided between a plurality of sorting carriages 13, and the supply of power to a plurality of sorting carriages 13 is effected via one sorting carriage 13. Referring to fig. 6, a signal transceiver 229 is disposed at the bottom of sorting cart 13, the signal transceiver 229 may be an encoder, and the signal transceiver 229 may cooperate with an external antenna 228 to transmit and receive command signals from controller 21, so that sorting cart 13 can communicate with controller 21. Of course, it is also possible that one of the sorting carts 13 is provided with a signal transceiver. Referring to fig. 7, an actuator 230 is disposed at the bottom of the sorting cart, and of course, an actuator 230 may be disposed at the bottom of at least one sorting cart 13 of all the sorting carts 13, and may receive a command signal from the controller 21 to control the start and stop of the driving roller 1321.

Of course, the signal transceiver 229 and the actuator 230 may not be separately provided, and the controller 21 may be provided with modules having functions of these two devices to directly control the controller 21. The skilled person can realize how to realize the transmission of signals among the controller 21, the actuator 230, and the signal transceiver 229, for example, the controller 21 may be a microprocessor, and the functions thereof may be realized according to internal programs thereof, which will not be described herein again.

It should be noted that the chain 12 is connected to the bottom of the trolley 13 through the connecting member 17, and the term "bottom" in the present invention means that the side close to the chain 12 is the bottom when the trolley 13 runs on the upper rail 111 in the first horizontal direction F1. When the trolley 13 travels in the first horizontal direction F1 on the lower rail 112, the "bottom" of the trolley 13 is still the side near the chain 12, not the bottom side.

Further, as shown in fig. 14 to 17, the roller 15 of one of the two

rollers

15,16 of the transfer mechanism 1 is an active roller 151, and the other roller 16 is a passive roller 161. The passive drum 161 includes: tension sprocket 1611, tension axle 1612, and tension assembly 1613. Tensioning sprocket 1611 engages chain 12. Tensioner shaft 1612 is disposed through the center of tensioner sprocket 1611. Tension assembly 1613 is connected to an end of tension axle 1612 and is configured to adjust the degree of tension of chain 12 by adjusting the displacement of tension axle 1612 in first horizontal direction F1.

Further, as shown in fig. 14-17, the tension assembly 1613 includes: a slide rail 16131, a tension spring 16134, a tension lever 16136, and a spring force adjustment assembly 16137.

The slide rail 16131 is fixedly disposed on the frame 11 along the first horizontal direction F1, as shown in fig. 12, in an embodiment, the slide rail 16131 is connected to the frame 11 by bolts. The slide rail 16131 is provided with a slide slot 16132 penetrating along the second horizontal direction F2, and an end of the tension axle 1612 penetrates through the slide slot 16132 along the second horizontal direction F2. An opening 16133 is further formed at an end of the slide rail 16131 away from the driving roller 151, and the opening 16133 is communicated with the slide slot 16132.

Further, as shown in fig. 15 and 16, the tensioning assembly 1613 further includes a blocking plate 16138 connected to an end surface of the tensioning axle 1612, the blocking plate 16138 is disposed on a side of the slide rail 16131 away from the tensioning sprocket 1611, and a dimension of the blocking plate 16138 in the vertical direction is greater than a width of the slide slot 16132. The purpose of the stop plate 16138 is to prevent the tension axle 1612 from sliding out of the side of the chute 16132, and the stop plate 16138 acts as a guide. Specifically, as shown in fig. 15 and 16, the blocking plate 16138 has a C-shaped cross section, and two guide grooves are provided on both upper and lower sides of the slide groove 16132 of the slide rail 16131, for engaging with both ends of the blocking plate 16138. In the present embodiment, the vertical direction refers to a direction perpendicular to and away from the ground.

The tension spring 16134 is connected to one end of the slide rail 16131 having an opening 16133 along a first horizontal direction F1, and the tension spring 16134 has a cavity 16135 extending therethrough along the first horizontal direction F1, the cavity 16135 communicating with the opening 16133.

The tension rod 16136 is sequentially inserted through the cavity 16135 of the tension spring 16134 and the sliding slot 16132 of the sliding rail 16131 along a first horizontal direction F1, defining one end of the tension rod 16136 located in the sliding slot 16132 of the sliding rail 16131 as a first end and the other end located in the sliding slot 16132 as a second end. The first end of the tension rod 16136 is connected to the end of the tension axle 1612, and when the tension rod 16136 moves in the first horizontal direction F1, the end of the tension axle 1612 is caused to slide in the slide channel 16132 in the first horizontal direction F1, and the second end of the tension rod 16136 extends out of the tension spring 16134. Referring to fig. 12, in the present embodiment, the cross section of the sliding slot 16132 is T-shaped, and specifically, the T-shaped slot is rotated clockwise by 90 °. This runner 16132 may be divided into a first through groove that is a rectangle extending in the first horizontal direction F1 and a second through groove that is a rectangle extending in the vertical direction (the direction perpendicular to the ground), and the first through groove and the second through groove communicate. The width of first logical groove rectangle and the size phase-match of tensioning shaft 1612 for tensioning shaft 1612 can slide along the upper and lower both sides of the rectangle of first logical groove, plays the spacing to tensioning shaft 1612, avoids tensioning shaft 1612 to rock from top to bottom along vertical direction. And the second through slot extends in a vertical direction in order to facilitate assembly of the tension rod 16136 with the tension axle in the second through slot, completing the connection, and moving into the first through slot.

Wherein the surface of the tension rod 16136 is threaded. For example, the tension rod 16136 is a lead screw having one end fixedly connected to the tension axle 1612. The tension rod 16136 may also be a threaded rod. Of course, in one embodiment, the tension rod 16136 may be a non-threaded rod, as long as one end of the rod can be fixedly connected to the axle 9, and is not limited thereto.

A spring force adjustment assembly 16137, disposed at an end of the tension spring 16134 remote from the slide rail 16131, couples the tension rod 16136 with the tension spring 16134 and compresses or stretches the tension spring 16134. The spring force adjustment assembly 16137 may be a nut. As shown in fig. 12, in this embodiment, the tension spring 16134 is initially in a compressed state, providing a pre-load force to the tension rod 16136. The elastic force adjusting component 16137 can adjust the compression length of the spring, so as to adjust the pre-tightening force. When the chain 12 loosens, the tension spring 16134 is stretched, and the tension rod 16136 is moved away from the driving roller 151, and the tension axle 1612 is slid along the sliding slot 16132 to tension the chain 12. In another embodiment, when the tension assembly 1613 is installed in an opposite direction to the first horizontal direction F1 in fig. 16 and 17, it may be configured to stretch the tension spring 16134 to provide a preload force in the same direction. Therefore, the tensioning assembly 1613 of the present invention can automatically perform tensioning compensation after the chain 12 is elongated due to long-term operation, thereby avoiding the occurrence of undesirable phenomena such as tooth disengagement and tooth jumping caused by the slack of the chain 12.

Further, as shown in fig. 15, in the present embodiment, the control system 2 further includes: a tension sensor 224. The tension sensor 224 is disposed on the frame 11, electrically connected to the controller 21, opposite the tension assembly 1613 in the first horizontal direction, configured to detect a distance between the tension assembly 1613 and the tension sensor, and send the distance to the controller 21 in the form of an electrical signal. At the same time, tension sensor 224 is also able to detect the distance X that tension sprocket 1611 has moved due to the slack in chain 12. If a large difference in the distance X between the two sides of the tension sprocket 1611 is detected, indicating that the chain 12 stretches between the two sides is not consistent, the chain 12 needs to be adjusted by the apparatus to prevent further damage to the apparatus.

Further, with continued reference to fig. 15, in the present embodiment, the control system 2 further comprises a sense patch 225. The sensor strip 225 is disposed at a second end of the tension bar 16136; wherein the tension sensor 224 is opposite to the sense piece 225 in the first horizontal direction, and is configured to detect a distance between it and the sense piece 225. The controller 21 determines the amount of deformation of the tension spring 16134 based on the distance, and when the tension spring 16134 is too long and the spring force is reduced, a prompt is issued to notify the operator to make a corresponding adjustment.
