DETAILED DESCRIPTION

[0031] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0032] Reference Figure 1-9 A continuous marshaling device at the end of a conveyor line comprises a first conveyor line 1 and a second conveyor line, wherein a predetermined angle exists between the first conveyor line 1 and the second conveyor line, and a cargo reversing device 3 is arranged between the first conveyor line 1 and the second conveyor line to attach Figure 1 For example, there is a 90° angle between the first conveyor line 1 and the second conveyor line. The goods on the second conveyor line need to be reversed by the goods reversing device 3 and conveyed to the upper end of the first conveyor line 1 for grouping. Finally, the grouped goods are transferred by a mechanical arm on one side to realize the terminal stacking process. It should be noted here that most of the goods are rectangular and are placed on pallets in a horizontal and vertical orientation. Finally, they need to be stacked in the same direction in the carriage. Therefore, the direction of the goods on the pallet that do not meet the requirements needs to be adjusted so that they can meet the needs of terminal stacking.

[0033] Please refer to the attached Figure 6 - Attachment Figure 8; The cargo reversing device 3 includes a reversing mounting frame 301, the inner wall of the reversing mounting frame 301 is rotatably connected to a reversing conveying roller 302, the upper end of the reversing mounting frame 301 is provided with a reversing accommodating opening, a negative pressure component 305 is arranged inside the reversing accommodating opening, the negative pressure component 305 is close to the inner wall of the first side of the reversing mounting frame 301, and there is a predetermined spacing between the two, and a jacking component 306 is arranged inside the reversing mounting frame 301, wherein the negative pressure component 305 is controlled to move linearly through the jacking component 306 to pass through the accommodating opening, when the direction of the cargo needs to be adjusted, the reversing conveying roller 302 is used to control the cargo to move to a predetermined position at the upper end of the cargo reversing device 3, and the direction of cargo transportation is defined as the front end, that is, the corner of the front end of the cargo is opposite to the position of the negative pressure component 305, and the negative pressure component 306 is used to control the negative pressure component 305 to move linearly through the negative pressure component 305. 5 The corners of the goods are adsorbed and fixed; then the reversing conveying roller 302 is controlled to rotate, and the side of the reversing conveying roller 302 away from the corner of the goods will rotate around the negative pressure component 305 during the rotation process, and finally the goods are rotated 90° to realize the reversing process of the goods; it should be noted here that when the corners of the goods are limited, the edges of the goods will continue to move under the action of friction, and the negative pressure component can rotate around its own axis. At this time, the goods can rotate with the negative pressure component 305 as the axis to realize the reversing process. Compared with the conventional method of setting two conveyor belts to move in different directions, the effect of this reversing method will not be affected by the posture and size of the goods, and the reversing process is fast, which improves the efficiency of cargo grouping and transportation.

[0034] A first electric control device is arranged in the reversing mounting frame 301, wherein the rotation of the reversing conveying roller 302 is controlled by the first electric control device, and the cargo reversing device 3 also includes a central controller, which is electrically connected to the first electric control device and the jacking assembly 306, wherein the first control device and the jacking assembly 306 are connected and controlled by the central controller, and the action process of the two is coordinated to quickly realize the reversal of the cargo; it should be noted here that compared with the traditional jacking mechanism for lifting and reversing the cargo, this method does not need to lift the cargo, and only needs to limit and fix the corners of the cargo during the transportation of the cargo, and then continue to control the rotation of the reversing conveying roller 302 to realize the reversal process of the cargo; compared with the traditional reversing method, this method is simple and convenient, does not require the jacking work process, improves the work efficiency, and can reverse the cargo of different weights, reducing the requirements for equipment load.

[0035] See attached drawings Figure 3 - Attachment Figure 5; Wherein the second conveyor line includes a cargo positioning conveyor line 4, the cargo positioning conveyor line 4 includes a positioning mounting frame 401, a cargo steering assembly 405 is provided at the first end of the cargo positioning conveyor line 4, the cargo steering assembly 405 includes a steering mounting frame 4051, and the inner wall of the steering mounting frame 4051 is rotatably connected to a plurality of steering conveying rollers 4053, a belt conveyor line 402 is provided in the positioning mounting frame 401, the belt conveyor line 402 extends toward the direction of the cargo steering assembly 405 and partially extends out, and a accommodating groove 4052 for accommodating the belt conveyor line 402 is provided on the side wall of the cargo steering assembly 405, wherein the conveying direction of the belt conveyor line 402 is inconsistent with the conveying direction of the steering conveying roller 4053, and the goods can be conveyed to the upper end of the cargo steering assembly 405 through the belt conveyor line 402, and the subsequent belt conveyor line 402 descends, and the goods are conveyed to the upper end of the cargo reversing device 3 through the cargo steering assembly 405 for reversing operation; wherein the belt conveyor The first end of the line 402 is movably connected to the positioning mounting frame 401, and the second end of the belt conveyor line 402 is provided with a lifting control unit 404. The lifting control unit 404 can adopt a common lifting hydraulic rod and an elastic sliding support, and its elastic sliding support is connected to the second end of the belt conveyor line 402, so as to realize the lifting and lowering control of the second end of the belt conveyor line 402, thereby allowing the belt conveyor line 402 to enter and exit the accommodating groove 4052; when the surface of the belt conveyor line 402 is higher than the steering conveyor roller 4053, the goods move synchronously on the belt conveyor line 402 during the conveying process to realize transmission; when the surface of the belt conveyor line 402 is lower than the top of the steering conveyor roller 4053, the goods are against the upper end of the steering conveyor roller 4053, and the goods can be transmitted through the steering conveyor roller 4053 to realize the transmission process, wherein the lifting control unit 404 controls the movement of the upper end of the belt conveyor line 402, which is a prior art and does not involve improvement, and will not be repeated here.

[0036] It should be noted here that the belt conveyor line 402 extends toward the direction of the cargo turning component 405 and is relatively long, so multiple cargoes can be conveyed simultaneously without affecting the efficiency of cargo conveying. When the detection element detects that the cargo at the top of the belt conveyor line 402 is located at a predetermined position above the cargo turning component 405, the lifting control unit 404 is controlled to drive the belt conveyor line 402 to descend, thereby realizing the cargo dropping process. During the dropping process, the belt conveyor line 402 can still control the movement of the cargo and control the cargo not to exceed the range and collide with the cargo turning component 405. In addition, an auxiliary supporting roller 403 can be installed on the inner wall of the positioning mounting frame 401. The auxiliary supporting roller 403 is against the inner wall of the surface of the belt conveyor line 402, so that the cargo at the upper end of the belt conveyor line 402 can be supported to ensure the stability of cargo transportation.

[0037] A positioning mounting plate is fixedly connected to the upper end of the steering mounting frame 4051, and a baffle 406 is installed on the side wall of the positioning mounting plate. An elastic member is arranged between the baffle 406 and the positioning mounting plate, and the elastic member can be selected as a sponge pad. The baffle 406 is located at the end of the belt conveyor line 402. By arranging the above components, the goods can be limited and blocked to prevent them from exceeding the working range, and the posture of the goods can also be corrected at the same time. In the process of the belt conveyor line 402 driving the goods to move, the end of the goods contacts and abuts against the side wall of the baffle 406, so that the surface of the goods is flush with the baffle, which is convenient for subsequent transportation.

[0038] A cargo temporary storage platform 5 is provided at the end of the second end of the cargo positioning conveyor line 4. The cargo temporary storage platform 5 includes a temporary storage mounting frame 501. The inner wall of the temporary storage mounting frame 501 is rotatably connected to a plurality of temporary storage conveying rollers 502. The outer wall of the temporary storage mounting frame 501 is provided with a second electric control device 503 for controlling the rotation of the temporary storage conveying rollers 502. The rotation of the temporary storage conveying rollers 502 is controlled by the second electric control device 503 to achieve control of the cargo. By providing the cargo temporary storage platform 5, the cargo can be temporarily stored. When the conveying speed of the cargo at the end is inconsistent, the cargo can be installed in an orderly manner at a certain distance and moved to the upper end of the belt conveyor line 402 by controlling the different rotations of the temporary storage conveying rollers 502, so as to ensure the continuous transportation of the cargo and improve the efficiency of cargo transportation.

[0039] Please refer to the attached Fig. 9; The lifting component 306 includes a lifting installation cylinder 3061, the inner wall of the lifting installation cylinder 3061 is slidably connected with a lifting piston 3064, the side wall of the lifting piston 3064 is fixedly connected with a lifting support rod 3062, the end of the lifting support rod 3062 passes through the lifting installation cylinder 3061 and is sealed and slidably connected thereto, the negative pressure component 305 is installed at the end of the lifting support rod 3062, a first chamber is formed between the lifting piston 3064 and the inner wall of the lifting installation cylinder 3061, the first chamber is connected with a negative pressure device, the first chamber is connected with the negative pressure component 305, an elastic element 3063 is connected between the lifting piston 3064 and the inner wall of the lifting installation cylinder 3061, wherein the negative pressure generated by the negative pressure device can reduce the pressure in the first chamber, thereby controlling the lifting piston 3064 to move upward so that the negative pressure component 305 at the upper end can It can move upward and press against the goods so that the negative pressure component 305 and the lower end of the goods are fixed by negative pressure. It should be noted here that the air hole diameter of the negative pressure suction cup 3051 is relatively small. When the negative pressure device generates negative pressure, its air extraction rate is greater than the air intake rate at the negative pressure suction cup 3051. The pressure difference generated at this time can drive the lifting piston 3064 to rise to realize the fixing process; and when the negative pressure component 305 rises to a predetermined position, the negative pressure device stops working after the fixation with the goods is completed; compared with the control of the traditional telescopic rod through the above-mentioned lifting component 306, its control process is simpler, and the negative pressure component 305 can be pressed against the lower end of the goods, and its control process is simpler. The control process can be realized by the negative pressure device, which is simple and reliable. The electrical control process in this article is all existing technology without improvement, and will not be repeated.

[0040] The negative pressure component 305 includes a negative pressure mounting plate 3052, and a plurality of negative pressure suction cups 3051 are fixedly connected to the upper end surface of the negative pressure mounting plate 3052, and the negative pressure suction cups 3051 are communicated with the first chamber, and the lower end of the negative pressure mounting plate 3052 is rotatably connected to the jacking support rod 3062 via a rotating connection 3053, and the rotating connection 3053 can be selected as a bearing, and a torsion elastic component is arranged between the jacking support rod 3062 and the negative pressure mounting plate 3052, and the torsion elastic component can be selected as a torsion spring, and under the action of the torsion spring, the negative pressure mounting plate 3052 can be in a predetermined position, and after the negative pressure suction cup 3051 is fixed to the cargo and the reversing conveying roller 302 is rotated, the cargo can rotate around the negative pressure component 305, thereby realizing the cargo reversal process.

[0041] A second chamber is formed between the lifting piston 3064 and the inner wall of the lifting installation cylinder 3061. The second chamber is connected to a storage box through a connecting pipe. Electrorheological fluid is arranged in the storage box. A conductive component is arranged at the bottom of the second chamber. The conductive component can be selected as two metal protrusions, which can conduct electricity to the electrorheological fluid. The current changes from liquid to solid under the conductive state, and the state conversion can be realized. The electrorheological fluid is an existing liquid; wherein the lifting support rod 3062 can suck the electrorheological fluid from the storage box into the second chamber during the lifting process, and the lifting piston 3064 and the lifting support rod 3062 can be fixed after the lifting component 306 is lifted and fixed, and the electrorheological fluid is controlled to be solid, so as to ensure the stability of the terminal negative pressure component 305 in the vertical position, and ensure its stable state, so as to avoid the negative pressure component 305 from being separated from the cargo during the turning process, resulting in the inability to turn the cargo; by arranging the electrorheological fluid in the second chamber, the stability of the lifting component 306 after lifting can be ensured.

[0042] The inner wall of the reversing mounting frame 301 is rotatably connected with a first posture correction roller 303 and a second posture correction roller 304, and the surfaces of the first posture correction roller 303 and the second posture correction roller 304 are fixedly connected with serpentine friction strips, which will generate tangential friction force during the rotation process; the first posture correction roller 303 and the second posture correction roller 304 are respectively located on both sides of the negative pressure component 305, wherein the first posture correction roller 303 and the second posture correction roller 304 are respectively controlled by the third electric control device and the fourth electric control device; by controlling the second posture correction roller 303 and the second posture correction roller 304, the first posture correction roller 303 and the second posture correction roller 304 are respectively controlled by the third electric control device and the fourth electric control device; The rotation of the correction roller 304 can control the distance between the goods before reversing and the inner wall of the reversing mounting frame 301, so that it is located at the upper end of the negative pressure component 305 at a suitable position, thereby ensuring the stability of the goods reversing; by controlling the rotation of the first posture correction roller 303, the goods after reversing can be adjusted, and the goods after reversing can be adjusted to correct the goods with deviations in the reversing angle; both of them play a role in assisting reversing; it should be noted here that when reversing, the corners of the goods are located at the inner wall of the reversing mounting frame 301 with a distance, which can ensure the stability of the goods when reversing.

[0043] Please refer to the attached Figure 1 , Attachment Figure 2 ; The first conveyor line 1 includes a conveyor mounting frame 101, and a plurality of load-bearing rollers 102 are rotatably connected to the inner wall of the conveyor mounting frame 101. A predetermined gap 103 is provided between two adjacent load-bearing rollers 102, and the size of the gap 103 is adapted to the size of the material fork at the end of the robot arm, so that the material fork can enter to realize the transfer and stacking of the goods; the load-bearing rollers 102 are all powered rollers, which can be controlled separately so that the goods can move at the upper end of the first conveyor line 1.

[0044] In the traditional setting mode, the robot arm can only realize the action and transfer the goods collectively after the goods at the upper end of the first conveyor line 1 are grouped. This often results in the phenomenon that the robot arm waits for the goods, or the goods wait for the robot arm. In order to overcome the above problems and improve the transportation efficiency of the goods; a temporary storage component 2 is arranged on one side of the first conveyor line 1, and the temporary storage component 2 includes a temporary storage mounting plate 202, a temporary storage material fork 201 is fixedly installed on the first side of the temporary storage mounting plate 202, and a first movable joint 203 and a second movable joint 204 are arranged on the second side of the temporary storage mounting plate 202, wherein the temporary storage mounting plate 202 is controlled by the first movable joint 203. The mounting plate 202 moves linearly in a first direction, and the first movable joint 203 is controlled to move linearly in a second direction through the second movable joint 204, wherein the first movable joint 203 and the second movable joint 204 can select common electric-controlled telescopic devices to control the temporary storage mounting plate 202 and the temporary storage material fork 201 to move in two directions to realize the control process; by setting the temporary storage component 2, after the goods are grouped at the upper end of the first conveyor line 1, the temporary storage material fork 201 is used to lift and temporarily store the goods to ensure the continuous transportation of subsequent goods and the continuous transfer of the robot arm, thereby improving the efficiency of goods transfer and stacking.

[0045] During the working process of the present invention, the goods that need to be stacked pass through the goods temporary storage platform, the goods positioning conveyor line, the goods reversing device, and the first conveyor line in sequence. The goods are conveyed, reversed, and grouped, and finally neatly stacked on the upper end of the first conveyor line. The robotic arm on one side of the first conveyor line can synchronously lift the neatly stacked goods, and quickly stack the goods at a predetermined position through the robotic arm to realize unmanned automatic and rapid stacking.

[0046] First, the goods are transported through the belt conveyor line from the upper end of the goods temporary storage platform to the predetermined position on the upper surface of the goods turning component. When the goods are at the predetermined position on the upper end of the goods turning component, the end of the belt conveyor line is controlled to descend by the lifting control unit. At this time, the end of the belt conveyor line enters the receiving groove and shrinks. The surface of the belt conveyor line is lower than the upper end surface of the steering conveyor roller. At this time, the goods are transferred and transported by the steering conveyor roller, so that the goods are turned to move toward the direction of the goods reversing device.

[0047] Then the goods are moved to the predetermined position under the drive of the reversing conveyor roller, that is, the corners of the front end of the moving goods are at the corresponding position of the negative pressure component. At this time, the negative pressure equipment works to control the lifting component to lift the negative pressure component at the top to make it against the lower end of the goods, and under the action of negative pressure, the negative pressure component fixes and limits the corners of the lower end of the goods to prepare for the subsequent reversal of the goods.

[0048] After the negative pressure component and the front corner of the goods are firmly attracted, the reversing conveyor roller is controlled to rotate again. Since the front corner of the goods is fixed, the rotating reversing conveyor roller can control the goods to move away from the corner, allowing it to rotate around the negative pressure component as the center. After rotating 90°, the goods are transformed from the first posture to the second posture that meets the stacking requirements. At this time, the negative pressure equipment and negative pressure components and other workpieces stop working, and the limit on the corners of the goods disappears.

[0049] Finally, the goods are linearly moved along the predetermined direction as needed and neatly placed at the upper end of the first conveyor line to complete the grouping process. The grouped goods can be temporarily stored through the temporary storage component, and the subsequent robotic arm can transfer the goods at the upper end of the temporary storage component.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
