[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, the cargo boxes are clamped front and back by the clamping pieces in the tallying components, and the output rod of the servo cylinder extends to push the two active racks to move. The movement of the active rack drives the driven gear meshing therewith to rotate clockwise, and drives the torsion shaft to rotate clockwise together. During the clockwise rotation of the torsion shaft, the flip bar is driven to rotate clockwise together, and the clamped multiple cargo boxes are flipped upward. When the flip bar is just rotated to be perpendicular to the top of the cargo cart, the downward gravity of the cargo box drives the sliding seat to slide downward along the light rod through the clamping piece, and the cargo box is placed on the top of the cargo cart. At the same time, the stacking and palletizing of the cargo boxes are realized, the tallying purpose of the cargo boxes is achieved, the manpower input is reduced, and the efficiency of cargo transportation at the terminal is improved.

[0021] 2. In the present invention, when the sliding seat slides downward along the light rod due to the gravity of the cargo box, the deceleration spring will be compressed, causing the deceleration spring to generate a rebound force, thereby slowing down the falling speed of the cargo box, preventing the cargo box from hitting the top of the cargo cart, and also preventing the upper layer of cargo boxes from hitting the top of the lower layer of cargo boxes, thereby preventing damage to the cargo, which is more beneficial for some fragile goods. It should be noted that the elastic force of the multiple deceleration springs in the device decreases one by one as it moves away from the torsion axis. The advantage of this is that when the flip bar is perpendicular to the top of the cargo cart, the latch component is released. In addition to the limiting effect on the sliding seat, the deceleration spring located at the bottom has the strongest elastic force. Therefore, the total weight of multiple cargo boxes in an upright state will not quickly compress the deceleration spring located at the bottom, ensuring that the deceleration spring at the bottom has sufficient deceleration effect on the bottom cargo box, avoiding the bottom cargo box from hitting the top of the cargo cart. At the same time, since the deceleration spring at the end farthest from the torsion axis has the weakest elastic force, it is ensured that the gravity of the top cargo box can overcome the elastic force of the deceleration spring and move downward, thereby compressing the deceleration spring to decelerate the top cargo box.

[0022] 3. In the present invention, during the clockwise rotation of the flip bar, the lock pin in the latch component is inserted into the inside of the lock head hole, so that when the flip bar does not reach a position perpendicular to the top of the cargo cart, the insertion effect of the lock pin and the lock head hole causes the sliding seat to not slide along the light rod, thereby preventing the cargo box from sliding down prematurely and interfering with the end of the cargo cart.

[0023] 4. In the present invention, the output shafts of the two servo motors drive the two ball screws to rotate, and the two ball screws drive the two bases to move axially along the two guide rods through the connection with the ball screw sleeves connected to their own threads. The movement of the two bases causes the two flip bars and the clamped cargo boxes to translate along the top of the cargo cart, and the cargo is moved to one end of the top of the cargo cart, so that the cargo boxes can be stacked and palletized in various areas on the top of the cargo cart.

[0037] A deceleration spring 2010 is fixedly installed between the fixed angle bracket 206 and a sliding seat 208 adjacent thereto, and a deceleration spring 2010 is also fixedly installed between two adjacent sliding seats 208. The deceleration springs 2010 are all located on the periphery of the polished rod 207.

[0038] The tally component also includes a plurality of key blocks 2011 fixedly mounted on the outer wall of the torsion shaft 204, the plurality of key blocks 2011 are distributed at equal angles, and the plurality of key blocks 2011 are located between the base 201 and the bearing seat 2017, a driven gear 2012 is slidably mounted on the outer wall of the torsion shaft 204, the driven gear 2012 is rotatably connected to the cylinder fixing seat 202 via a plane bearing, a key slot 2013 is provided on the inner wall of the driven gear 2012, the inner wall of the key slot 2013 is slidably connected to the outer wall of the key block 2011, and the base A thrust seat 2014 is fixedly installed at one end of 201, and a servo cylinder 2015 is fixedly installed on a side of the thrust seat 2014 away from the base 201. The output rod of the servo cylinder 2015 movably passes through the thrust seat 2014, and an active rack 2016 is fixedly installed at the end of the output rod of the servo cylinder 2015. The bottom of the active rack 2016 is slidably connected to the top of the base 201, and the active rack 2016 is located at the bottom of the key slot 2013, and the active rack 2016 and the key slot 2013 are meshed with each other;

[0039] Specifically, in this embodiment, the dock workers first place the cargo boxes on the dock floor one by one, and place them between the two flip bars 205. At the same time, each cargo box is placed between the front and rear clamping pieces 209 (see FIG. Figure 1 As shown in the figure, at the same time, another dock worker pushes the cargo cart 5 to the top of the loading platform 1 and starts the front and rear electric cylinders 203. The output rods of the two electric cylinders 203 push the two torsion shafts 204 toward the middle. During the movement of the two torsion shafts 204 toward the middle, the front and rear flip bars 205 and each clamping piece 209 are driven to move toward the middle together. After the front and rear clamping pieces 209 complete the front and rear clamping of the cargo box, the electric cylinder 203 is stopped, and the front and rear servo cylinders 2015 are started immediately. The output rods of the two servo cylinders 2015 extend. The two active racks 2016 are pushed to move, and the active rack 2016 moves to drive the driven gear 2012 meshing therewith to rotate clockwise, and the driven gear 2012 is torque-limited between the key slot 2013 and the key block 2011 and the torsion shaft 204, so the rotation of the driven gear 2012 drives the torsion shaft 204 to rotate clockwise together, and the two torsion shafts 204 rotate clockwise while the two flip bars 205 rotate clockwise together, flipping the clamped multiple cargo boxes upwards, when the flip bar 205 just rotates perpendicular to the top of the cargo cart 5 (as shown in the attached figure), the cargo cart 5 is turned to the left and right sides of the cargo cart 5. Figure 2As shown in the figure, the downward gravity of the cargo box drives the sliding seat 208 to slide downward along the light rod 207 through the clamping piece 209, and the cargo box is placed on the top of the cargo cart 5, and at the same time, the stacking and palletizing of the cargo boxes are realized, and the purpose of tallying the cargo boxes is achieved, which reduces manpower input and improves the efficiency of cargo transportation at the terminal. In addition, while the sliding seat 208 slides downward along the light rod 207, the deceleration spring 2010 is compressed, causing the deceleration spring 2010 to generate a rebound force, thereby slowing down the speed of the cargo box falling, preventing the cargo box from hitting the top of the cargo cart 5, and also preventing the cargo box on the upper layer from hitting the top of the cargo box on the lower layer, thereby avoiding damage to the cargo, which is more beneficial for some fragile goods. It should be noted that the elastic force of the multiple deceleration springs 2010 in the device increases as it moves away from the torsion axis 204. The one end of the cargo cart 5 is gradually reduced. The advantage of this is that when the flip bar 205 is perpendicular to the top of the cargo cart 5, after the latch component releases the limiting effect on the sliding seat 208, the deceleration spring 2010 located at the bottom has the strongest elastic force. Therefore, the total weight of multiple cargo boxes in an upright state will not quickly compress the deceleration spring 2010 located at the bottom, ensuring that the deceleration spring 2010 at the bottom has sufficient deceleration effect on the bottom cargo box, avoiding the bottom cargo box from hitting the top of the cargo cart 5. At the same time, since the deceleration spring 2010 at the end farthest from the torsion shaft 204 has the weakest elastic force, that is, ensuring that the gravity of the cargo box at the top can overcome the elastic force of the deceleration spring 2010 and move downward, thereby compressing the deceleration spring 2010 to decelerate the top cargo box.

[0040] In the second embodiment, a latch component is rotatably provided at one end of the loading platform 1, and the latch component is used to limit the position of the goods;

[0041] The latch component includes two guide seats 301 fixedly mounted at both ends of a side away from the two flip bars 205, a slide bar 302 is slidably mounted inside the two guide seats 301, a side of the flip bar 205 close to the slide bar 302 is penetrated with a plurality of equally spaced telescopic square grooves 2001, a locking pin 303 is slidably mounted inside the telescopic square groove 2001, a rectangular groove 304 is penetrated through a side of the locking pin 303 facing the guide seat 301, the slide bar 302 movably penetrates the rectangular groove 304, a first magnetic block 305 is fixedly mounted on the inner wall of the rectangular groove 304 away from the clamping sheet 209, and a plurality of second magnetic blocks 305 are fixedly mounted on the side of the slide bar 302 away from the flip bar 205 06 and a plurality of third magnetic blocks 307, the magnetism of the second magnetic block 306 is opposite to that of the first magnetic block 305, and the magnetism of the third magnetic block 307 is the same as that of the first magnetic block 305, a U-shaped groove 3010 is provided at one end of the slide bar 302 close to the torsion shaft 204, a guide wheel 3011 is rotatably installed inside the U-shaped groove 3010, a convex ring 309 is fixedly installed on one side of the bearing seat 2017 close to the cylinder fixing seat 202, the convex ring 309 is located on the periphery of the torsion shaft 204, the outer wall of the guide wheel 3011 abuts against the outer wall of the convex ring 309, a locking hole 2008 is provided on one side of the sliding seat 208 away from the clamping sheet 209, and the locking pin 303 is inserted into the locking hole 2008;

[0042] The first magnetic block 305 and the second magnetic block 306 are alternately distributed on the side of the slide bar 302, and the outer surface of the lock pin 303 is fixedly installed with a limit block 308;

[0043] A spring support plate 3013 is fixedly installed at one end of the flip bar 205 away from the torsion shaft 204. The spring support plate 3013 is located at the end of the slide bar 302, and a return spring 3014 is fixedly installed between the spring support plate 3013 and the end of the slide bar 302.

[0044] Specifically, in this embodiment, when the flip bar 205 rotates clockwise, the lock pin 303 in the latch component is inserted into the lock head hole 2008. During the clockwise rotation of the flip bar 205, the two guide seats 301 drive the slide bar 302 and the guide wheel 3011 to rotate together, and also drive multiple lock pins 303 to rotate together. When the flip bar 205 rotates perpendicular to the top of the cargo cart 5, the guide wheel 3011 just moves along the outer wall of the convex ring 309 to its top, thereby pushing the slide bar 302 along the two guide seats 301 in the direction away from the convex ring 309, the reset spring 3014 is compressed, and during the slide bar 302 being pushed, it drives the second magnetic block 306 and the third magnetic block 307 to move together. The wheel 3011 moves to the top of the convex ring 309, and the third magnetic block 307 just moves to the inside of the rectangular groove 304 and corresponds to the first magnetic block 305. Since the third magnetic block 307 has the same magnetic property as the first magnetic block 305, a mutual repulsive force is generated between the third magnetic block 307 and the first magnetic block 305, thereby pushing the locking pin 303 along the telescopic square groove 2001 in the direction away from the clamping piece 209, causing the locking pin 303 to be withdrawn from the inside of the lock hole 2008, releasing the limiting effect on the sliding seat 208. Therefore, the downward gravity of the cargo box drives the sliding seat 208 to slide downward along the light rod 207 through the clamping piece 209, and the cargo box is placed on the top of the cargo cart 5, while realizing the stacking and palletizing of the cargo box.

[0045] In the third embodiment, a translation component is provided on the top of the loading platform 1, and the translation component is used for parallel transportation of goods;

[0046] The translation component includes two left and right support seats 401 fixedly installed at the front end of the top of the loading platform 1 and two left and right support seats 401 located at the rear end of the top of the loading platform 1, wherein a ball screw 402 is rotatably installed between the left and right support seats 401, and two ball screw sleeves 404 are threadedly sleeved on the outer walls of the ball screw 402, and the top of the ball screw sleeve 404 is fixedly connected to the bottom of the base 201, wherein a servo motor 403 is fixedly installed on the left side of the left support seat 401, and the servo motor 403 is located at the end of the ball screw 402, and the output shaft of the servo motor 403 is fixedly connected to the end of the ball screw 402 through a coupling;

[0047] A guide rod 405 is fixedly installed between the left and right support seats 401, and a guide hole 406 is formed through the adjacent side surfaces of the two ball screw sleeves 404, and the inner wall of the guide hole 406 is slidably connected to the outer wall of the guide rod 405;

[0048] Specifically, in this embodiment, when the flip bar 205 rotates clockwise, the multiple cargo boxes clamped are flipped upward. When the two flip bars 205 rotate to form a 60° angle with the loading platform 1, the bottom of a cargo box located at one end closest to the torsion shaft 204 is higher than the top height of the cargo cart 5. At this time, the worker continues to start the two servo motors 403. The output shafts of the two servo motors 403 drive the two ball screws 402 to rotate. The two ball screws 402 drive the two bases 201 to move axially along the two guide rods 405 through the connection with the ball screw sleeves 404 threadedly connected to each other. The movement of the two bases 201 causes the two flip bars 205 and the clamped cargo boxes to translate along the top of the cargo cart 5, and move the cargo to one end of the top of the cargo cart 5, so as to facilitate the stacking of cargo boxes in various areas on the top of the cargo cart 5.

[0049] In the present invention, a bulk cargo automatic tallying and conveying device for dock operation is used. First, the dock workers place the cargo boxes on the dock floor one by one and place them between two turning bars 205. At the same time, each cargo box is placed between two front and rear clamping pieces 209 as shown in the attached figure. Figure 1 As shown, at the same time, another dock worker pushes the cargo cart 5 to the top of the loading platform 1;

[0050] Then, the front and rear two electric cylinders 203 are started, and the output rods of the two electric cylinders 203 push the two torsion shafts 204 toward the middle. During the movement of the two torsion shafts 204 toward the middle, the front and rear two flip bars 205 and each clamping piece 209 are driven to move toward the middle together, until the front and rear clamping pieces 209 complete the front and rear clamping of the cargo box, and then the electric cylinder 203 is stopped, and the front and rear two servo cylinders 2015 are started immediately, and the output rods of the two servo cylinders 2015 extend out to push the two active racks 2016 to move. The movement of the active rack 2016 drives the driven gear 2012 meshing therewith to rotate clockwise, and the driven gear 2012 is torque-limited between the keyway 2013 and the key block 2011 and the torsion shaft 204, so the rotation of the driven gear 2012 will drive the torsion shaft 204 to rotate clockwise together, and the two torsion shafts 204 rotate clockwise. During this period, the two flip bars 205 are driven to rotate clockwise together, and the multiple cargo boxes clamped are flipped upward. When the two flip bars 205 rotate to form a 60° angle with the loading platform 1, the bottom of a cargo box located at one end closest to the torsion axis 204 is higher than the top height of the cargo cart 5. At this time, the worker continues to start the two servo motors 403. The output shafts of the two servo motors 403 drive the two ball screws 402 to rotate. The two ball screws 402 drive the two bases 201 to move axially along the two guide rods 405 through the connection with the ball screw sleeves 404 threadedly connected to each other. The movement of the two bases 201 causes the two flip bars 205 and the clamped cargo boxes to translate along the top of the cargo cart 5, and move the cargo to one end of the top of the cargo cart 5. When the cargo reaches one end of the top of the cargo cart 5, the flip bar 205 just rotates perpendicular to the top of the cargo cart 5 as shown in the attached figure. Figure 2 As shown, the two servo motors 403 are immediately turned off;

[0051] When the flip bar 205 rotates clockwise, the two guide seats 301 drive the slide bar 302 and the guide wheel 3011 to rotate together, and also drive the multiple lock pins 303 to rotate together. When the flip bar 205 rotates perpendicular to the top of the cargo cart 5, the guide wheel 3011 just moves along the outer wall of the convex ring 309 to its top, thereby pushing the slide bar 302 along the two guide seats 301 in the direction away from the convex ring 309, and the return spring 3014 is compressed. When the slide bar 302 is pushed, it will drive the second magnetic block 306 and the third magnetic block 307 to move together. When the guide wheel 3011 moves to the top of the convex ring 309, the third magnetic block 307 just moves The third magnetic block 307 and the first magnetic block 305 have the same magnetic properties, so a mutual repulsion force is generated between the third magnetic block 307 and the first magnetic block 305, thereby pushing the locking pin 303 along the telescopic square slot 2001 in a direction away from the clamping piece 209, causing the locking pin 303 to be withdrawn from the inside of the lock head hole 2008, releasing the limiting effect on the sliding seat 208. Therefore, the downward gravity of the cargo box drives the sliding seat 208 to slide downward along the light rod 207 through the clamping piece 209, placing the cargo box on the top of the cargo cart 5, and at the same time realizing the stacking and palletizing of the cargo boxes, and realizing the sorting of the cargo boxes. The purpose is to reduce manpower input and improve the efficiency of cargo transportation at the dock. During the period when the sliding seat 208 slides downward along the light rod 207, the deceleration spring 2010 will be compressed, causing the deceleration spring 2010 to generate a rebound force, thereby slowing down the falling speed of the cargo box, preventing the cargo box from hitting the top of the cargo cart 5, and also preventing the upper layer of cargo boxes from hitting the top of the lower layer of cargo boxes, thereby avoiding damage to the cargo, which is more beneficial for some fragile goods. It should be noted that the elastic force of the multiple deceleration springs 2010 in the device decreases one by one as it moves away from the torsion shaft 204. The advantage of this is that when the flip bar 205 is perpendicular to the top of the cargo cart 5, the latch part After the limiting effect of the sliding seat 208 is released, the deceleration spring 2010 at the bottom has the strongest elastic force. Therefore, the total weight of multiple cargo boxes in an upright state will not quickly compress the deceleration spring 2010 at the bottom, ensuring that the deceleration spring 2010 at the bottom has sufficient deceleration effect on the bottom cargo box, avoiding the bottom cargo box from hitting the top of the cargo cart 5. At the same time, since the deceleration spring 2010 at the end farthest from the torsion shaft 204 has the weakest elastic force, it is ensured that the gravity of the top cargo box can overcome the elastic force of the deceleration spring 2010 and move downward, thereby compressing the deceleration spring 2010 to decelerate the top cargo box.

[0052] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
