[0061] Example 1

[0062] See also Figures 1 to 2In order to design an automatic swing arm trolley 100 that can be applied to different types of truck compartments, when the automatic swing arm trolley 100 is put into use, it can achieve the effects of stable transportation, simple operation, compact structure and space saving. In the first aspect, this embodiment 1 provides an automatic swing arm trolley 100.

[0063] First, the automatic swing arm trolley 100 mainly includes three parts: a trolley body 10 , a first telescopic conveying part 20 and a loader 30 .

[0064] In order to make the structure of the automatic swing arm trolley 100 more compact, the first telescopic conveying part 20 is arranged on the top of the trolley body 10 along the conveying direction of the goods 200, wherein the first telescopic conveying part 20 includes a slewing bearing device 2001, a transition conveyor 2002, a movable conveyor 2003 and an end conveyor 2004. One end of the end conveyor 2004 is connected to the trolley body 10 through the slewing bearing device 2001, and one end of the movable conveyor 2003 is slidably connected to the other end of the end conveyor 2004 through a linear guide rail 2005. When the linear guide rail 2005 is driven to move, the movable conveyor 2003 slides on the end conveyor 2004 to extend or retract within the length dimension of the freight car 300, and at the same time, one end of the transition conveyor 2002 is connected to the other end of the movable conveyor 2003 through the slewing bearing device 2001, and the transition conveyor 2002 The other end is welded to the loader 30 so that the loader 30 can rotate relative to the first telescopic conveying part 20.

[0065] Secondly, the loader 30 mainly includes a second telescopic conveying part 1 connected to the other end of the transition conveyor, a connecting part 2 movably connected to the second telescopic conveying part 1, a turning conveying device 3 connected to the connecting part 2, and a steering assist conveying device 4 rotatably installed on the turning conveying device 3. A driving component 40 is connected to the bottom of the second telescopic conveying part 1, and the driving component 40 is connected to the trolley body 10. The second telescopic conveying part 1 is connected to the turning conveying device 3 through the connecting part 2, and is used to control the turning conveying device 3 to swing in the height dimension of the truck compartment 300, swing in the width dimension of the truck compartment 300, and swing in the length and width dimensions of the truck compartment 300 at the same time, thereby further improving the activity space of the loader 30 inside the truck compartment 300, and having good flexibility in controlling the movement of the loader 30.

[0066] Finally, the drive assembly 40 is installed in the trolley body 10. The drive assembly 40 includes a turntable mechanism 4001 and a mechanical swing arm 4002. The mechanical swing arm 4002 is connected to the second telescopic conveying part 1 and is used to control the tilting and swinging of the second telescopic conveying part 1. The turntable mechanism 4001 is connected to the mechanical swing arm 4002. The slewing support device 2001 at the connection between the transition conveyor 2002 and the second telescopic conveying part 1 rotates along the same axis as the turntable mechanism 4001, so that when the turntable mechanism 4001 is driven to rotate, the second telescopic conveying part 1 can be controlled to produce a yaw swing relative to the first telescopic conveying part 20, thereby further expanding the activity space of the loader 20 in the truck compartment 300.

[0067] Further details and specific implementation of the connection part 2 are provided in the following. Figure 3 arrive Figure 4 The connecting part 2 mainly includes two parts: a U plate 201 and a joint gear assembly 202.

[0068] First, the articulated gear assembly 202 is movably connected to the second telescopic conveying part 1. When the second telescopic conveying part 1 is controlled, the articulated gear assembly 202 movably connected to the second telescopic conveying part 1 is driven to rotate. At this moment, the rotation direction of the articulated gear assembly 202 shows a downward or upward movement trend relative to the conveying direction of the goods 200, thereby making the directional conveying device 3 swing upward or downward.

[0069] Secondly, the open end of the U-plate 201 is movably connected to the articulated gear assembly 202, and the closed end is fixedly connected to the direction-adjusting conveying device 3. When the U-plate 201 is controlled, the U-plate 201 movably connected to the articulated gear assembly 202 moves in a direction perpendicular to the movement direction of the articulated gear assembly 202. At this time, the U-plate 201 moves to the left or right along the conveying direction of the goods 200. At the same time, the direction-adjusting conveying device 3 fixed on the U-plate 201 swings to the left or right.

[0070] Finally, a steering-assisting conveying device 4 that rotates along the same conveying line is connected to the steering conveying device 3. When the goods 200 are conveyed on the steering conveying device 3, they will first undergo a steering process to achieve the direction of the outer packaging label of the goods 200, so that the outer packaging of the goods 200 finally stacked on the truck compartment has the same orientation. After the goods 200 are adjusted in orientation, when they are conveyed to the steering-assisting conveying device, the steering-assisting conveying device 4 is driven to rotate, and the goods 200 on the steering-assisting conveying device 4 change direction to adapt to different stacking methods.

[0071] Further, the second telescopic conveying part 1 is further refined and implemented. Please refer to Figures 3 to 4From the structural composition of the second telescopic conveying part 1, the second telescopic conveying part 1 mainly includes three parts: a fixed conveying bracket 101, a linear drive mechanism 102 and a movable conveying bracket 103, wherein the movable conveying bracket 103 is connected to the fixed conveying bracket 101 through the linear drive mechanism 102, and a first driving source 5, a second driving source 6 and a first transmission member 7 are respectively provided on both sides of the movable conveying bracket 103, wherein the first driving source 5 is connected to one end of the joint gear assembly 202 through the first transmission member 7, and the second driving source 6 is connected to the other end of the joint gear assembly 202 through the first transmission member 7.

[0072] From the motion state of the second telescopic conveying part 1, there are: first, the linear drive mechanism 102 on the second telescopic conveying part 1 is driven to work, so that the movable conveying bracket 103 is driven by the linear drive mechanism 102 to extend forward or retract backward along the fixed conveying bracket 101. Through the telescopic process of the second telescopic conveying part 1, when the goods 200 are transported along the stacking direction of the truck compartment 300, it can adapt to different types of truck compartment 300 lengths.

[0073] Secondly, when the first driving source 5 installed on one side of the movable conveying bracket 103 on the second telescopic conveying portion 1 is driven, the joint gear assembly 202 moves upward or downward.

[0074] When the second driving source 6 installed on the other side of the movable conveying bracket 103 on the second telescopic conveying portion 1 is driven, the U plate 201 moves to the left or right.

[0075] When the first driving source 5 and the second driving source 6 mounted on the movable conveying bracket 103 on the second telescopic conveying portion 1 are driven simultaneously, the joint gear assembly 202 moves upward or downward while the U plate 201 also moves leftward or rightward.

[0076] Further details and specific implementations of the joint gear assembly 202 are available in the following. Figure 4 , wherein the joint gear assembly 202 mainly includes two parts: a shaft group 2021 and a bevel gear transmission box 2022.

[0077] First, in order to ensure the structural stability of the articulated gear assembly 202 during operation, thereby further improving the stability of the loader 30 during operation, the bevel gear transmission box 2022 is fixed on the shaft group 2021, and the two ends of the bevel gear transmission box 2022 are movably connected to the U plate 201.

[0078] Secondly, both ends of the shaft group 2021 are movably mounted on the movable conveying bracket 103, and one end of the shaft group 2021 is connected to the first driving source 5 through the first transmission member 7. When the first driving source 5 is driven, the force is transmitted to the shaft group 2021 at this time through the first transmission member 7, so that the shaft group 2021 starts to rotate, and drives the bevel gear transmission box 2022 fixed on the shaft group 2021 to rotate together, so that the bevel gear transmission box 2022 as a whole can move upward or downward under the push of the first driving source 5.

[0079] The other end of the shaft group 2021 is connected to the second drive source 6 through the first transmission member 7. When the second drive source 6 is driven, the force is transmitted to the shaft group 2021 through the first transmission member 7. The shaft group 2021 starts to rotate and drives the U-plate 201 connected to the joint gear assembly 202 to move together, so that the U-plate 201 can move upward or downward under the drive of the first drive source 5.

[0080] In addition, the first transmission member 7 can be a synchronous belt or a connecting rod.

[0081] Further details and specific implementation of the directional conveying device 3 are provided in the following. Figure 5 The redirecting conveying device 3 mainly includes three parts: a first frame 301, two first conveying parts 302 arranged side by side on the first frame 301, and a suction cup rotating mechanism 303 arranged between the two first conveying parts 302. In order to ensure that the goods 200 can be reliably conveyed on the loader 30, the adsorption surface of the suction cup rotating mechanism 303 is aligned with the conveying surface of the first conveying part 30.

[0082] Further, the sucker rotating mechanism 303 is further refined and implemented, please refer to Figure 5 The suction cup rotating mechanism 303 includes two parts: a vacuum suction cup 3031, a rotating shaft 3032 and a lifting cylinder 3033.

[0083] First, several vacuum suction cups 3031 are connected to the lifting cylinder 3033. When the lifting cylinder 3033 is driven, the lifting cylinder 3033 realizes the upward lifting or downward movement. At the same time, the several vacuum suction cups 3031 connected to the lifting cylinder 3033 also move together with the lifting cylinder 3033, thereby realizing the upward or downward movement of the vacuum suction cups 3031.

[0084] Secondly, the rotating shaft 3032 is connected to the lifting cylinder 3033. When the rotating shaft 3032 is driven to rotate, the lifting cylinder 3033 connected to the rotating shaft 3032 also rotates, so that the vacuum suction cup 3031 connected to the lifting cylinder 3033 rotates.

[0085] Furthermore, the arrangement around the suction cup rotating mechanism 303 is further improved and implemented. For details, please refer to Figures 5 to 6 In order to ensure that the goods 200 do not deviate from the conveying center position after the rotation and adjustment process, and thus avoid falling during the subsequent conveying process, hinge swing arms 8 are provided on both sides of the suction cup rotation mechanism 303, and the hinge swing arms 8 are installed on the first frame 301. When the goods 200 are rotated and adjusted to the marked direction on the loader 30, the hinge swing arms 8 on both sides of the suction cup rotation mechanism 303 are driven to move, and the goods 200 with the marked direction after the rotation and adjustment are clamped and straightened, so as to ensure that the goods 200 can be conveyed normally along the conveying center.

[0086] The hinge swing arm 8 includes three parts: a swing portion 801 , a driving mechanism 802 and a second transmission member 803 .

[0087] First, from the perspective of the structural connection relationship of the hinge swing arm 8, the second transmission member 803 passes through the first frame 301, the first frame 301 is provided with a driving mechanism 802, the swinging part 801 is divided into two groups and is respectively provided on both sides of the first frame 301, and the driving mechanism 802 is connected to the swinging part 801 through the second transmission member 803, so that the swinging parts 801 on both sides swing synchronously relative to the first frame 301.

[0088] In order to avoid interference between components when transmitting force to the swing part 801 and affecting the working stability of the swing part 801, the second transmission member 803 is installed by passing through the clearance hole provided on the first frame 301, wherein the second transmission member 803 can be a belt, a chain, or a connecting rod. Specifically, a belt can be used for transmission, wherein the type of belt is a synchronous belt.

[0089] Secondly, from the working principle of the hinge swing arm 8: when the goods 200 on the loader 30 are rotated and adjusted, when the goods 200 are transported to the vicinity of the driving mechanism 802, the driving mechanism 802 starts to work, thereby transmitting the force to the swing part 801 through the second transmission member 803, so that the swing part 801 moves synchronously towards each other to straighten and reset the goods 200 after the rotation and adjustment, thereby preventing the goods 200 from falling during the subsequent transportation process.

[0090] Furthermore, from the two aspects of the structural composition and connection relationship of the steering-assisting conveying device 4 and the motion state of the steering-assisting conveying device 4, the steering-assisting conveying device 4 is further refined and implemented. For details, please refer to Figure 7 .

[0091] The first aspect is from the perspective of the various structures and connection relationships of the steering-assisting conveying device 4: the steering-assisting conveying device 4 includes three parts: a second frame 401, a second conveying part 402 provided on the second frame 401 along the conveying direction, and a rotating joint part 403 connected to the end of the second conveying part 402 opposite to the conveying direction. The rotating joint part 403 is coaxially connected to the third driving source 9. Because the rotating joint part 403 and the third driving source 9 are coaxially connected on the same conveying line, the overall structure of the steering-assisting conveying device 4 is more compact and the volume occupies a smaller volume, thereby making the overall structure of the loader 30 smaller, so that the loader 30 occupies less space when working, thereby further improving the utilization rate of the internal space of the truck compartment 300.

[0092] Secondly, from the motion state of the steering-assisting conveyor 4, when the third driving source 9 is not driving the rotating joint 403, the second frame 401 and the first frame 301 are on the same horizontal line, and the second frame 401 is in a horizontal state. At the same time, the goods 200 on the steering-assisting conveyor 4 are transported in the initial placement direction.

[0093] When the third driving source 9 drives the rotating joint part 403 to rotate 90° clockwise or counterclockwise, the position of the second frame 401 relative to the first frame 301 is in a vertical state. At this moment, the conveying surface of the steering-assisting conveyor device 4 is in a vertical state relative to the conveying surface of the direction-adjusting conveyor device 3. At this moment, the goods 200 on the steering-assisting conveyor device 4 are conveyed in a direction perpendicular to the original placement direction.

[0094] Further, the second conveying unit 402 is further refined and expanded with specific implementation methods. Figure 8 and Figure 9 The second conveying part 402 includes two parts: a conveying structure 4021 and a suction cup mechanism 4022, and the second conveying part 402 includes a boosting mechanism 40211 and a transportation mechanism 40212. The boosting mechanisms 40211 are divided into two groups and are respectively arranged on both sides of the transportation mechanism 40212.

[0095] In order to ensure that the goods 200 can be fixed on the conveying surface of the conveying structure 4021 before turning, the suction cup mechanisms 4022 are divided into two groups and are symmetrically arranged on both sides of the conveying structure 4021.

[0096] In order to ensure that the goods 200 can carry out the subsequent transportation process synchronously after turning, the transportation structure 4021 is connected to one end of the rotating joint part 403. Before the rotating joint part 403 is driven to rotate, the suction cup mechanism 4022 is first used to adsorb and fix the goods 200, and then the goods 200 is rotated and adjusted. At this time, the goods 200 no longer need to change the work position. It only needs to drive the boosting mechanism 40211 to push the goods 200, and it can be directly transported to the truck compartment 300 for stacking, thereby further simplifying the structure of the loader 30, reducing the volume share of the loader 30 when operating in the internal space of the truck compartment 300, and further improving the space utilization rate inside the truck compartment 300.

In order to ensure the stability and operational flexibility during the use of the automatic swing arm trolley 100, this embodiment 2 provides a method for using the automatic swing arm trolley 100 in the second aspect. This method can be specifically applied to the automatic swing arm trolley 100 in the above embodiment. For details, please refer to Figures 10 to 11 , wherein the method for using the automatic swing arm trolley 100 includes the following steps:

[0099] S1: First place the lifting platform 400 at the cargo entrance of the truck compartment 300, then move the automatic swing arm trolley 100 onto the lifting platform 400, and adjust the height of the lifting platform 400 so that the table top of the lifting platform 400 and the bottom flat plate of the truck compartment 300 are on the same horizontal line, so that the automatic swing arm trolley 100 can be moved to the interior of the truck compartment 300.

[0100] S2: The telescopic belt conveyor 500 at the end of the production line is connected to the end conveyor 2004;
