[0001] The invention belongs to the technical field of production lines, and in particular relates to a small packet flow shuttle vehicle used for material transportation in a small packet flow intelligent production line. Background Art

[0002] For many years, the production and manufacturing of the garment industry has generally adopted the "bundling" operation method, that is, several pieces of clothing or semi-finished products are bundled and moved and sewn in the processing order, and each process is completed by one or a group of workers. This traditional method has many disadvantages: there are many work-in-progress in the workshop, the finished products are slow to be produced, quality problems are not easy to be discovered in time, the production department cannot correctly formulate production plans, rush work is frequent, and the workshop is seriously wasted.

[0003] To solve the above problems, intelligent production lines for small packet flows have emerged in recent years. For example, the invention patent with application number CN202410974002.4 discloses an intelligent production line for small packet flows, which has the following features: 1. Conveying and circulation mechanism: including tracks and feeding trolleys that can move between working units; 2. Feeding trolley structure: It has a feeding trolley base that supports the material box, a trolley head, a telescopic feeding mechanism and a travel drive mechanism; 3.

[0013] As a further improvement of the present invention, the first driving unit is configured as a DC cylinder, which is connected to the connecting plate. The DC cylinder drives the connecting plate to move forward and backward along the first guide rod, thereby driving the vehicle body shift plate to move forward and backward synchronously.

[0014] As a further improvement of the present invention, the second driving unit is configured as a second servo motor and a second reducer, and the transmission assembly includes a connecting shaft, a synchronous wheel and a synchronous belt, wherein: The connecting shaft is connected to the output end of the second reducer through a coupling; The synchronous wheels are provided in a pair, one of which is mounted on the connecting shaft, and the pair of synchronous wheels are respectively located at two ends of the synchronous belt; The connecting shaft is driven to rotate by the second servo motor, thereby realizing the rotation of the synchronous wheel and the synchronous belt.

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical method of the present invention, but the present invention is not limited to these embodiments.

[0021] like Figure 1-13 As shown, the present invention provides a small packet flow shuttle vehicle, comprising: A feeding trolley 100 that can move along a conveying track 500 to any placement station 510, and a mounting base plate 210 is provided on the feeding trolley 100; The lifting mechanism 200 includes a lifting gallows 220 and a carrying platform 230. The lifting gallows 220 is arranged on the mounting base plate 210 and can be lifted up and down in the vertical direction. The carrying platform 230 is arranged on the lifting gallows 220 and is used to carry the feed box. The left and right lateral movement mechanism 400 is used to drive the lifting mechanism 200 to move and switch between the left and right side workstations.

[0022] When the feeding trolley 100 moves to a certain placement station 510, the lifting mechanism 200 is adjusted to the position directly below the placement station 510 through the left and right transverse movement mechanism 400, and then the lifting mechanism 200 is lifted up and down to place the feed box on the placement station 510 or remove the feed box on the placement station 510.

[0023] This jacking-type feeding trolley 100 structure can directly pick up and place the supply box from the bottom of the storage station 510 by jacking up and down. In actual application, compared with the solution of transferring material boxes to both sides of the production line in the prior art, it greatly reduces the lateral footprint of the production line, thereby greatly reducing the space occupation cost of the factory.

[0024] Preferably, the feeding trolley 100 is also provided with a front and rear shifting mechanism 300, which includes a mounting frame 310, a first driving unit, and a vehicle body shifting plate 320. The mounting frame 310 is provided with a pair and is respectively connected to the front and rear sides of the mounting base 210. The first driving unit is used to drive the vehicle body shifting plate 320 to move along the front and rear directions.

[0025] Preferably, the left and right transverse movement mechanism 400 includes a linear guide rail 410, a second drive unit, a transmission assembly and a drive plate 420. The linear guide rail 410 and the bottom plate of the mounting frame 310 are connected via a slider. The second drive unit drives the drive plate 420 to move left and right along the axis direction of the linear guide rail 410 via the transmission assembly. The drive plate 420 is connected to the bottom plate of the mounting frame 310. The movement of the drive plate 420 drives the mounting frame 310 and the mounting bottom plate 210 to move left and right synchronously, that is, drives the lifting mechanism 200 and the front and rear toggle mechanism 300 to move left and right.

[0026] The shuttle provided in this embodiment has integrated lifting, forward and backward movement, and left and right lateral movement functions in its structure, so that the shuttle can be flexibly operated in a narrow space to complete the actions of picking up and placing supply boxes, reducing the need for additional operating space, and is particularly suitable for compact intelligent production line environments.

[0027] The specific working principle is as follows: 1. When the feeding trolley 100 moves to a certain placement station 510, the lifting mechanism 200 and the front-back shifting mechanism 300 are driven to the position directly below the placement station 510 by the left-right lateral movement mechanism 400; 2. The forward and backward toggle mechanism 300 is actuated to open the placement station 510, so that the feed box can pass upward or downward through the placement station 510; 3. The lifting mechanism 200 drives the carrying platform 230 to rise and fall by lifting the lifting gallows 220, so as to achieve the purpose of the feeding trolley 100 taking and placing the feeding box from the bottom of the storage station 510.

[0028] Further, the lifting mechanism 200 is supplemented as follows: Preferably, the lifting gallows 220 comprises: The driving rocker arm 221 and the crank rocker arm 222 are hinged to form a linkage mechanism; A plurality of gallows rods 223 are arranged crosswise, with one group arranged on each side and the two groups connected by a pulling rod 224. At the same time, one end of the crank rocker arm 222 away from the driving rocker arm 221 is connected to the pulling rod 224. The mounting base 210 is provided with a hinge seat 211 and a sliding seat 212 distributed front and back; The end of a gallows rod 223 at the bottom of the lifting gallows 220 is hinged to the hinge seat 211; The end of another gallows rod 223 at the bottom of the lifting gallows 220 is connected to the sliding seat 212 through a roller bearing 225; Specifically, the operating principle is as follows: when the lifting gallows 220 is lifted up and down, one gallows rod 223 rotates around the hinge seat 211 , and the other gallows rod 223 moves forward and backward along the sliding seat 212 through the roller bearing 225 .

[0029] The structure of the lifting gallows 220 adopts a combination of an articulated seat 211 and a sliding seat 212, which not only provides a stable support point, but also allows the gallows rod 223 to flexibly adjust its position as needed. Through the synergy between the driving rocker arm 221, the crank rocker arm 222 and the pulling rod 224, precise motion control of the gallows rod 223 is achieved, which greatly enhances the stability of the entire lifting mechanism 200 during the lifting process and improves the safety and accuracy of material handling.

[0030] Preferably, the lifting mechanism 200 also includes a first servo motor 240 and a first reducer 250 connected to each other, and the output end of the first reducer 250 is connected to an end of the driving rocker arm 221 away from the crank rocker arm 222. The first servo motor 240 drives the driving rocker arm 221 and the crank rocker arm 222 to rotate in coordination, thereby pulling the pulling rod 224 downward or pushing it upward to achieve the lifting and lowering of the lifting gallows 220.

[0031] Further, the front and rear toggle mechanism 300 is supplemented as follows: Preferably, the front and rear toggle mechanism 300 further includes: The first guide rod 330, both ends of which are fixed and arranged on the mounting frame 310, serves as a guide track for the vehicle body shift plate 320 to move forward and backward; The connecting plate 340 and the first linear bearing 350 are sleeved on the first guide rod 330 , the connecting plate 340 is arranged on the first guide rod 330 , and the vehicle body shifting plate 320 is arranged at both ends of the connecting plate 340 .

[0032] Among them, the first driving unit is set as a DC cylinder 360, which is connected to the connecting plate 340. The DC cylinder 360 drives the connecting plate 340 to move forward and backward along the first guide rod 330, and drives the vehicle body shift plate 320 to move forward and backward synchronously. The moving trajectory of the connecting plate 340 is controlled by the DC cylinder 360, thereby realizing precise control and stable movement of the vehicle body shift plate 320.

[0033] The supplementary description of the left and right lateral movement mechanism 400 is as follows: Preferably, the second driving unit is configured as a second servo motor 430 and a second reducer 440, and the transmission assembly includes a connecting shaft 450, a synchronous wheel 460 and a synchronous belt 470, wherein: The connecting shaft 450 is connected to the output end of the second reducer 440 through a coupling; A pair of synchronous wheels 460 is provided, one synchronous wheel 460 is installed on the connecting shaft 450, and the pair of synchronous wheels 460 are respectively located at both ends of the synchronous belt 470; Specifically, when the second servo motor 430 is started, it transmits power to the connecting shaft 450 through the second reducer 440, and the connecting shaft 450 drives the synchronous wheel 460 installed thereon to rotate, and then makes another synchronous wheel 460 rotate synchronously through the synchronous belt 470. The movement of the synchronous belt 470 finally drives the driving plate 420 to move left and right along the axial direction of the linear guide rail 410, thereby realizing the action of the left and right transverse movement mechanism 400.

[0034] The entire transmission assembly adopts a compact layout, and all components are highly integrated, which saves space and is easy to install and maintain.

[0035] It should be noted that racks 471 are provided on the inner and outer surfaces of the synchronous belt 470, and a tooth groove 421 is provided on the bottom surface of the driving plate 420. The driving plate 420 and the synchronous belt 470 are connected by meshing racks 471 and tooth grooves 421. The design of the racks 471 on the inner and outer surfaces of the synchronous belt 470 provides extremely high transmission accuracy, ensuring that the moving distance and position of the driving plate 420 are accurate, thereby ensuring the precise movement of the lifting mechanism 200 and the front and rear toggle mechanism 300.

[0036] In addition, in order to further improve the stability of the feeding trolley when taking and placing the feed box, left and right guide plates 231 are provided on the left and right sides of the load-bearing platform 230, and front and rear guide columns 260 are provided on the mounting base 210. The front and rear guide columns 260 are respectively on the front and rear sides of the load-bearing platform 230, wherein the left and right guide plates 231 and the front and rear guide columns 260 are both provided with guide slopes, and the left and right guide plates 231 and the front and rear guide columns 260 together enclose a space for placing the feed box, and the setting of the guide slopes enables the feed box to fall smoothly onto the load-bearing platform 230 without problems of deflection or jamming, thereby improving the stability and reliability of subsequent actions.

[0037] To better illustrate the application scenarios of the above-mentioned lifting type small packet flow shuttle vehicle, the following is a description of the intelligent production line using the lifting type small packet flow shuttle vehicle: The production line includes: The conveying track 500 is provided with at least two lines arranged on the left and right along the length direction, and each line is provided with a plurality of placement stations 510, each placement station 510 is used to place a feed box, and a track system is provided at the bottom of the conveying track 500 and is used for the feed trolley 100 to move forward and backward; The placement station 510 has a pair of relatively movable placement plates 520 for placing the feed box, wherein: The feeding trolley 100 moves the lifting mechanism 200 and the front-back shifting mechanism 300 to the bottom of the placement station 510 through the left-right lateral movement mechanism 400; The feeding trolley 100 lifts the feeding box upwards and moves up and down through the lifting mechanism 200; The feeding trolley 100 moves the pair of storage plates 520 away from each other through the forward and backward shifting mechanism 300, so that the pair of storage plates 520 are separated to have enough space for the supply box to pass through.

[0038] The specific working principle is as follows: 1. When the feeding trolley 100 moves to the designated placement station 510, the left and right lateral movement mechanism 400 accurately positions the lifting mechanism 200 and the front and rear shifting mechanism 300 directly below the placement station 510; 2. The forward and backward shifting mechanism 300 is actuated to shift the pair of storage plates 520 in a direction away from each other, so that the two plates are separated to form a space large enough for the feed box to pass through; 3. The lifting mechanism 200 drives the carrying platform 230 to rise by moving the lifting gallows 220 up and down, and lifts the feed box from the bottom of the storage station 510 and lifts it to an appropriate height; 4. After the pick-up and place operation is completed, the lifting mechanism 200 is lowered, the front and rear toggle mechanism 300 is reset, and the storage plate 520 is restored to the initial position, ready for the next operation.

[0039] The actions of the front and rear toggle mechanism 300 and the lifting mechanism 200 are adjusted in sequence according to the picking up and placing of the feed box, for example: When the feeding trolley 100 takes the feeding box from the storage station 510, the positions of the lifting mechanism 200 and the front-back toggle mechanism 300 are adjusted by the left-right lateral movement mechanism 400, and then the lifting gallows 220 is raised, and the carrying platform 230 lifts the feeding box upwards, and finally the front-back toggle mechanism 300 is actuated to toggle the pair of storage plates 520 in a direction away from each other, and the lifting gallows 220 is lowered, completing the action of taking the feeding box; On the contrary, when the feeding trolley 100 needs to place the feed box at a certain storage station 510, the positions of the lifting mechanism 200 and the front-rear sliding mechanism 300 are first adjusted by the left and right transverse movement mechanism 400, and then the front-rear sliding mechanism 300 is actuated first and moves a pair of storage plates 520 away from each other, the lifting gallows 220 rises again and allows the feed box to pass upward from the storage station 510, the front-rear sliding mechanism 300 is reset and the storage station 510 is reset, the feed box is successfully set up on the storage station 510, and finally the lifting gallows 220 is reset.

[0040] In other words, the entire intelligent production line only needs to reserve space for the feeding trolley 100 to move at the bottom of the conveying track 500, and no additional space needs to be reserved on both sides of the production line, which has the beneficial effect of improving space utilization.

[0041] In addition, the description of how the front-rear shifting mechanism 300 shifts the pair of storage plates 520 in the direction away from each other is as follows: Preferably, a material box paddle 521 is provided on the outer side of the storage plate 520. After the material box paddle 521 is buckled with the vehicle body paddle 320, the movement of the vehicle body paddle 320 drives the material box paddle 521 and the storage plate 520 to move. When the feeding trolley 100 moves forward and backward along the track system, the body shifting plate 320 and the material box shifting plate 521 are kept in a staggered arrangement; When the feeding trolley 100 moves to the bottom of the placement station 510 and the front and rear shifting mechanism 300 is driven by the left and right lateral movement mechanism 400 to move left and right to the bottom of the placement station 510 , the vehicle body shifting plate 320 is engaged with the material box shifting plate 521 .

[0042] That is to say, when the feeding trolley 100 moves in a straight line along the track system, the body paddle plate 320 and the material box paddle plate 521 will not interfere with each other, and the feeding trolley 100 always moves between the two storage stations 510. Once the feeding trolley 100 is moved into place, the front and rear paddle mechanism 300 is driven to move left and right to the bottom of the storage station 510 through the left and right transverse movement mechanism 400. At this time, the body paddle plate 320 and the material box paddle plate 521 will be automatically engaged, and then the material box paddle plate 521 can be smoothly pulled outward through the action of the body paddle plate 320, thereby achieving the purpose of opening the storage station 510.

[0043] Furthermore, the installation structure of the storage plate 520 is described as follows: First, the conveying track 500 is provided with a second guide rod 530 along its conveying direction, and a second linear bearing 540 is provided on the guide rod. At the same time, the two ends of the storage plate 520 are integrally connected with a bending plate 522, and the bending plate 522 is connected to the second linear bearing 540, that is, the storage plate 520 can move along the second guide rod 530 through the bending plate 522 and the second linear bearing 540, so as to achieve the purpose of opening or closing the storage station 510; It also includes a return spring 550, one end of which is fixed and the other end is connected to the bending plate 522. When the pair of storage plates 520 move away from each other and open the storage station 510, the return spring 550 is in a stretched state. Therefore, when the vehicle body paddle plate 320 is separated from the material box paddle plate 521, the pair of storage plates 520 can be automatically reset under the action of the return spring 550.

[0044] Preferably, the conveying track 500 is also provided with a manual button 560 on the side of each storage station 510. When the trolley is needed to pick up and place the feed box, the staff located next to the storage station 510 only needs to press the manual button 560, and the control system will automatically control the feeding trolley 100 to move to the storage station 510 and pick up and place the feed box. This manual button 560 combined with the control system's way of issuing instructions to the feeding trolley realizes a seamless connection from manual triggering to automatic execution, embodies the concept of intelligent production, improves the system's degree of automation, and thus improves work efficiency.

[0045] Preferably, the conveying track 500 is also provided with a loading guide plate 570 arranged vertically downward at each placement station 510, and its bottom has a guiding slope. The loading guide plate 570 plays the same role as the left and right guide plates 231 and the front and rear guide columns 260 on the feeding trolley 100, and is mainly used for guiding when the feeding trolley 100 lifts the supply box upward and places it on the placement station 510.

[0046] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above technical means, but also include technical schemes composed of any combination of the above technical features. The above is a specific implementation of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.

[0047] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0048] In addition, in the present invention, descriptions such as "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.
