Description

Technical Field

[0001] This invention relates to the field of cargo picking device technology, specifically cargo picking devices for logistics transportation. Background Technology

[0002] Goods picking devices used in logistics transportation are efficient and automated equipment primarily used to quickly and accurately select target goods from large quantities of cargo. The working principle of goods picking devices is mainly based on automatic identification, control, and sorting technologies. Specifically, it first identifies and locates the barcodes and labels on the cartons using an identification system. Then, according to instructions from the control system, it uses sorting devices to remove the target cartons from the conveyor system and deliver them to the designated destination. Existing goods picking devices generally use a scanner to scan the cartons and then push them out from the corresponding exit using a cylinder at one end, allowing them to fall onto the corresponding low-level conveyor belt for final transport and consolidation for packing and shipping.

[0003] However, existing logistics picking devices still have significant shortcomings in practical applications. For example, most existing logistics picking devices use a single speed conveyor belt with fixed baffles to sort goods, which makes it difficult to effectively solve the problems of goods stacking, offset, or excessive spacing. This leads to multiple items entering the barcode scanning area at the same time, causing recognition failure or misjudgment. After the goods are identified, they usually need to be temporarily stored in the corresponding collection box. Existing collection systems mostly use a fixed collection position design. When the collection box is full, it must be manually stopped and replaced, which not only interrupts the sorting process and reduces the continuity of the overall operation, but also increases the labor intensity of the operators. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art and provide a goods picking device for logistics transportation. To solve the above problems, by setting up sorting components, the speed difference between the limiting frame, rollers and two conveyor belts can be used to realize the rapid single-row arrangement of goods and increase the spacing, prevent crowding, improve barcode scanning efficiency, and by setting up replacement components, the collection box can be pushed out and replaced with a spare box when it is full, and an alarm can be issued when the collection box is about to run out, ensuring continuous operation.

[0011] Furthermore, one end of the push block passes through the limiting groove and extends into the storage cavity. A threaded hole that mates with the lead screw is provided on one side of the push block, and the lead screw is threadedly connected to the push block.

[0030] This application provides a goods picking device for logistics transportation.

The following provides a detailed description of this goods picking device for logistics transportation. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of embodiments.

[0031] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0032] Please see Figure 1-11This embodiment provides a cargo picking device for logistics transportation, comprising: a conveyor belt support 1, a support 2 on one side of the conveyor belt support 1, and a housing 6 on one side of the support 2; a sorting assembly disposed between the conveyor belt support 1 and the support 2, the sorting assembly comprising: multiple driven conveyor rollers a102 inside the conveyor belt support 1, an active conveyor roller a101 inside the conveyor belt support 1, the other end of the active conveyor roller a101 protruding from one side of the conveyor belt support 1 and fixedly connected to a large pulley 301, a servo motor a3 on one side of the large pulley 301, an active conveyor roller b201 inside the support 2, one end of the active conveyor roller b201 protruding from one side of the support 2 and fixedly connected to a small pulley 302, the large pulley 301 and the small pulley 302... A belt 303 is provided between the conveyor belt support 1 and the support 2. Two limit frames 401 are provided between the two limit frames 401 and multiple rollers 402 are rotatably connected inside the two limit frames 401 via a rotating shaft. A replacement component is provided on one side of the support 2 and the box 6. The replacement component includes: a storage cavity 602 is opened inside the box 6, and multiple collection boxes 603 are provided inside the storage cavity 602. A base 7 is fixedly installed on one side of the box 6. A servo motor b701 is fixedly installed on the top of the base 7. A lead screw 704 is provided on one side of the box 6. A driven bevel gear 703 is fixedly connected to the outside of the lead screw 704. The servo motor b701 is driven by a drive bevel gear 702 via a rotating shaft. A push block 705 is provided on the outside of the lead screw 704. An electric push rod 205 is fixedly installed at the bottom of the support 2.

[0033] By setting up the sorting component, the goods can be quickly sorted into a single column and spaced apart according to the automatic arrangement effect formed by the guide frame 401 and roller 402 and the speed difference between conveyor belt a103 and conveyor belt b203, thus avoiding the goods from crowding into the scanning area and improving the efficiency of goods barcode scanning. Secondly, by changing the component settings, the collection box 603 can be pushed out when it is full and the spare collection box 603 can be moved into place. At the same time, an alarm can be issued to remind the operator to replenish the collection box 603 when it is about to run out, thereby ensuring the continuity of operation. Next, by setting the ejection component, when the scanner 901 fails to read the barcode of the goods, the electric telescopic rod 501 is triggered to drive the push plate 502 to push the abnormal goods into the recycling bin 204, so as to realize the goods picking.

[0034] Among them, one end of the active conveyor roller a101 is connected to the conveyor belt support 1 through a bearing, the servo motor a3 is connected to the large pulley 301 through a drive shaft, the support 2 is provided with multiple driven conveyor rollers 202, one end of the active conveyor roller b201 is connected to the support 2 through a bearing, both ends of the multiple driven conveyor rollers 202 are respectively connected to the support 2 through bearings, and a conveyor belt b203 is provided between the active conveyor roller b201 and the driven conveyor rollers 202; two fixed rods 4 are fixedly connected to one side of each of the two limit frames 401, and one end of the two fixed rods 4 is respectively connected to the conveyor belt support 1 and the support 2; both ends of the multiple driven conveyor rollers a102 are respectively connected to the conveyor belt support 1 through bearings, and a conveyor belt a103 is provided between the active conveyor roller a101 and the driven conveyor rollers a102.

[0035] In operation, the servo motor a3 is started by the controller located on one side of the conveyor belt support 1. The servo motor a3 drives the large pulley 301 to rotate, which in turn drives the small pulley 302 and the belt 303 to rotate. This rotation of the large pulley 301 and the small pulley 302 drives the active conveyor rollers a101 and b201 to rotate, which in turn drives multiple driven conveyor rollers a102, multiple active conveyor rollers b201, the conveyor belt a103, and the conveyor belt b203 to rotate. Because the diameter of the large pulley 301 is larger than that of the small pulley 302, when the large pulley 301 drives the small pulley 302 to rotate via the belt 303, the rotation speed of the small pulley 302 will be faster than that of the large pulley 301, and the rotation speed of the conveyor belt a103 will be slower than that of the conveyor belt b203. At this point, goods are placed one by one at intervals on top of the conveyor belt a103, with the barcodes facing upwards. The conveyor belt a103 transports the goods towards the scanner 901. When the goods move between the two limit frames 401, the multiple rollers 402 on the inclined sides of the two limit frames 401, in conjunction with the conveyor belt a103, cause the goods to move between the two limit frames 401 and arrange themselves one by one in the channel formed by the two limit frames 401 until the goods at the front enter the top of the conveyor belt b203. Since the rotation speed of the conveyor belt b203 is faster than that of the conveyor belt a103, when the goods move onto the conveyor belt b203, the goods will accelerate forward, widening the distance between the goods still at the top of the conveyor belt a103 and moving to the bottom of the scanner 901. At this time, the displacement sensor c902 located on one side of the bracket 2 senses the goods, generates an electrical signal, and transmits the electrical signal to the industrial microcontroller 505. The industrial microcontroller 505 shuts down the servo motor a3 and turns on the scanner 901 to scan the barcode on the goods.

[0036] The collection box 603 has multiple wheels at its bottom, and slots 605 are opened on both sides of the box body 6. A limit groove 604 is opened on one side of the inner wall of the storage cavity 602. A displacement sensor b802 is installed on one side of the inner wall of the storage cavity 602. An equipment box b8 is fixedly connected to one side of the box body 6. A buzzer 801 is installed inside the equipment box b8. A pressure sensor 601 is installed on one side of the inner wall of the storage cavity 602. An equipment box a504 is fixedly installed on one side of the bracket 2. An industrial microcontroller 505 is installed inside the equipment box a504. One end of the push block 705 passes through the limit groove 604 and extends into the storage cavity 602. A threaded hole is opened on one side of the push block 705 to cooperate with the lead screw 704. The lead screw 704 is threadedly connected to the push block 705. One end of the lead screw 704 is connected to the box body 6 through a bearing, and the other end of the lead screw 704 is connected to the base 7 through a bearing. The driving bevel gear 702 and the driven bevel gear 703 are meshed together.

[0037] After the goods are scanned, the conveyor belt b203 continues to transport the goods to the other end of the support 2, where they continuously fall into the collection box 603 located on one side of the support 2. When the collection box 603 is full, the operator controls the electric push rod 205 to extend via the controller on one side of the conveyor belt support 1. This, in conjunction with the wheels at the bottom of the collection box 603, pushes the collection box 603 out of the box body 6 through the slot 605. Then, the operator controls the electric push rod 205 to reset and starts the servo motor b701 via the controller. The servo motor b701 rotates the drive bevel gear 702, causing... The driven bevel gear 703 and lead screw 704 rotate, driving the push block 705 to move along the direction of the lead screw 704. This, in conjunction with the wheels at the bottom of the collection box 603, pushes the collection box 603 inside the storage cavity 602, causing the collection box 603 closest to the bracket 2 inside the storage cavity 602 to move to the side of the pressure sensor 601 and come into contact with the pressure sensor 601. At this time, the pressure sensor 601 is subjected to pressure, generates an electrical signal, and transmits the electrical signal to the industrial microcontroller 505. The industrial microcontroller 505 then shuts down the servo motor b701, thereby realizing the replacement of the collection box 603.

[0038] Furthermore, the pressure sensor 601 is a piezoelectric pressure sensor, model number 8507C-1. When external pressure is applied to the sensor, the piezoelectric element inside the pressure sensor 601 deforms, thereby generating a corresponding charge. These charges are detected and amplified through appropriate electronic circuits, ultimately resulting in a voltage or current signal output proportional to the input pressure, thereby shutting down the servo motor b701. The pressure sensor 601 is a mature and conventional technology in this field, and this solution does not improve the circuit or program of the pressure sensor 601. Therefore, the circuit and signal connection relationships of the pressure sensor 601 will not be described in detail.

[0039] The bracket 2 has a push-out assembly on one side, which includes: a mounting bracket 9 on the top of the bracket 2, a scanner 901 fixedly mounted on the top of the inner wall of the mounting bracket 9, and multiple displacement sensors c902 fixedly mounted on both sides of the inner wall of the bracket 2; a mounting platform 5 fixedly mounted on one side of the bracket 2, an electric telescopic rod 501 fixedly mounted on the top of the mounting platform 5, a push plate 502 fixedly connected to one end of the electric telescopic rod 501, and a displacement sensor a503 fixedly mounted on one side of the push plate 502; a recycling trough 204 is opened on one side of the bracket 2, and a recycling box 506 is placed on one side of the bracket 2.

[0040] When goods move to scanner 901, scanner 901 attempts to read the barcode. If the reading is successful, industrial microcontroller 505 marks the goods as valid and simultaneously controls servo motor a3 to start normally, allowing the goods to continue to be transported normally without triggering displacement sensor a503. If the barcode cannot be read, industrial microcontroller 505 marks it as another type or a certain type, simultaneously controls servo motor a3 to start normally, and triggers displacement sensor a503. At this time, displacement sensor a503 generates an electrical signal and transmits it to industrial microcontroller 505. Industrial microcontroller 505 controls servo motor a3 to shut down and controls electric telescopic rod 501 to fully extend, driving push plate 502 to push the goods through recycling trough 204 and drop them into recycling bin 506. Then, it controls electric telescopic rod 501 to reset and restarts servo motor a3.

[0041] Furthermore, displacement sensors a503, b802, and c902 are laser displacement sensors, model number JGWY3. In use, these sensors measure the target object and output electrical signals based on the measurement results. These raw electrical signals are input into the industrial microcontroller 505, which processes the signals and compares them with preset thresholds or target values. This solution does not modify the circuitry or program of displacement sensors a503, b802, and c902; therefore, the circuitry and signal connections of displacement sensors a503, b802, and c902 will not be described in detail.

[0042] The working principle is as follows: In operation, the servo motor a3 is started by the controller located on one side of the conveyor belt support 1. The servo motor a3 drives the large pulley 301 to rotate, which in turn drives the small pulley 302 and the belt 303 to rotate. This rotation of the large pulley 301 and the small pulley 302 drives the active conveyor rollers a101 and b201 to rotate, which in turn drives multiple driven conveyor rollers a102, multiple active conveyor rollers b201, the conveyor belt a103, and the conveyor belt b203 to rotate. Because the diameter of the large pulley 301 is larger than that of the small pulley 302, when the large pulley 301 drives the small pulley 302 to rotate via the belt 303, the rotation speed of the small pulley 302 will be faster than that of the large pulley 301, and the rotation speed of the conveyor belt a103 will be slower than that of the conveyor belt b203. At this point, goods are placed one by one at intervals on top of the conveyor belt a103, with the barcodes facing upwards. The conveyor belt a103 transports the goods towards the scanner 901. When the goods move between the two limit frames 401, the multiple rollers 402 on the inclined sides of the two limit frames 401, in conjunction with the conveyor belt a103, cause the goods to move between the two limit frames 401 and arrange themselves one by one in the channel formed by the two limit frames 401 until the goods at the front enter the top of the conveyor belt b203. Since the rotation speed of the conveyor belt b203 is faster than that of the conveyor belt a103, when the goods move onto the conveyor belt b203, the goods will accelerate forward, widening the distance between the goods still at the top of the conveyor belt a103 and moving to the bottom of the scanner 901. At this time, the displacement sensor c902 located on one side of the bracket 2 senses the goods, generates an electrical signal, and transmits the electrical signal to the industrial microcontroller 505. The industrial microcontroller 505 shuts down the servo motor a3 and turns on the scanner 901 to scan the barcode on the goods.

[0043] Furthermore, when the goods move to the scanner 901, the scanner 901 attempts to read the barcode. If the reading is successful, the industrial microcontroller 505 marks the goods as valid and simultaneously controls the servo motor a3 to start normally, allowing the goods to continue to be transported normally without triggering the displacement sensor a503. If the barcode cannot be read, the industrial microcontroller 505 marks it as another type or a certain type, and simultaneously controls the servo motor a3 to start normally and triggers the displacement sensor a503. At this time, the displacement sensor a503 generates an electrical signal and transmits it to the industrial microcontroller 505. The industrial microcontroller 505 controls the servo motor a3 to shut down and controls the electric telescopic rod 501 to fully extend, driving the pusher plate 502 to push the goods through the recycling trough 204 and drop them into the recycling bin 506. Then, the electric telescopic rod 501 is reset and the servo motor a3 is restarted.

[0044] After the goods are scanned, the conveyor belt b203 continues to transport the goods to the other end of the support 2, where they continuously fall into the collection box 603 located on one side of the support 2. When the collection box 603 is full, the operator controls the electric push rod 205 to extend via the controller on one side of the conveyor belt support 1. This, in conjunction with the wheels at the bottom of the collection box 603, pushes the collection box 603 out of the box body 6 through the slot 605. Then, the operator controls the electric push rod 205 to reset and starts the servo motor b701 via the controller. The servo motor b701 rotates the driving bevel gear 702, causing the driven bevel gear 703 and the lead screw 704 to rotate, which in turn drives the push block 705 to move along the direction of the lead screw 704, thereby cooperating with the wheels at the bottom of the collection box 603 to push it. The collection box 603 inside the storage cavity 602 moves the collection box 603 closest to the bracket 2 to the side of the pressure sensor 601 and makes contact with the pressure sensor 601. At this time, the pressure sensor 601 is subjected to pressure, generates an electrical signal, and transmits the electrical signal to the industrial microcontroller 505. The industrial microcontroller 505 shuts down the servo motor b701, thereby realizing the replacement of the collection box 603. When there is only one collection box 603 left in the storage cavity 602, the displacement sensor b802 detects a change in the distance between itself and the object directly in front, generates an electrical signal, and transmits it to the industrial microcontroller 505. The industrial microcontroller 505 controls the buzzer 801 to emit a buzzing sound to remind the operator to replenish the collection box 603.
