Description

Technical Field

[0001] The present disclosure relates to the field of intelligent logistics loading, and particularly to the technical field of an end loader for an automatic swing arm trolley. Background Art

[0002] The automatic swing arm trolley is one of the components of the automatic loading system. The automatic loading system can be used in the automated loading operations for round-trip transportation between the logistics distribution centers of production bases in industries such as tobacco, medicine, retail, mechanical electronics, automotive, food and beverage, wine, electricity meters, and chemical industries. Among them, the end loader is connected to the automatic swing arm trolley through a connecting part, and by controlling the connecting part on the automatic swing arm trolley, the end loader conveys goods from the end of the production line or the indoor warehouse to the truck carriage for stacking.

[0003] However, the trucks used for logistics distribution are usually van trucks of different models, and van trucks of different models have differences in the length, width, and height of the carriage. As a result, the end loader will be restricted by the three-dimensional space inside the carriage during transportation. Therefore, it is a difficult problem for the end loader to adapt to different types of trucks during operation and stack the goods correctly in the carriage.

[0004] To solve the above-mentioned problems, in the related art, Chinese Patent CN201510064044.5 provides a container rapid automatic loading and stacking machine, which has an automatic walking frame-shaped rack, a conveyor belt is installed at the bottom of the frame-shaped rack, left and right lifting guide rails are installed at the front end of the frame-shaped rack, a lifting platform is installed on the two lifting guide rails, and a box pushing mechanism that moves up and down together with the lifting platform, a lifting drive mechanism equipped with the lifting platform and the box pushing mechanism, and a left and right transverse movement mechanism is also installed on the lifting platform; and a flipping type material pushing mechanism is installed on the upper part of the frame-shaped rack. This mechanism includes left and right horizontal guide rails arranged in the front-rear direction, a sliding seat is installed on the horizontal guide rails, a drive mechanism for the forward and backward movement of the sliding seat is equipped, a flipping mechanism and a flipping box pushing plate are installed on the sliding seat, and a PLC controller is equipped to control the automatic walking mechanism, conveyor belt, box pushing mechanism, lifting drive mechanism, transverse movement mechanism, and each power machine in the flipping type material pushing mechanism in the frame-shaped rack.

[0005] However, when the inventor specifically implemented the above solution, it was found that there were the following defects:

[0006] 1. It is not stable enough during use. The lifting platform is controlled by a power machine to control the lifting drive mechanism and the transverse movement mechanism to achieve upward or downward, left or right movements respectively. When conveying along the direction of the carriage, it adapts to the stacking positions in the height dimension of the carriage and the width dimension. For the stacking position in the length dimension, the PLC controller is required to control the automatic walking frame-shaped rack to complete forward or backward movement along the conveying direction, which may cause the goods on the automatic walking frame-shaped rack to jolt and fall.

[0007] 2. It is not flexible enough during use. Both the lifting drive mechanism and the transverse movement mechanism are installed on the frame-shaped rack, and the conveyor belt installed on the frame-shaped rack and the lifting drive mechanism are not on the same horizontal line. The degree of freedom of the lifting drive mechanism is not high, so it cannot convey goods while lifting. It can only lift the goods first and then push the lifted goods onto the conveyor belt for conveying, and the operation process is complex.

[0008] It will occupy a large amount of internal space of the carriage during use. The lifting drive mechanism is equipped with a lifting platform, the transverse movement mechanism is installed on the lifting platform, and a box-pushing mechanism is also installed on the lifting platform. The connection structure of each component of such an automatic loading and stacking machine is relatively complex, and the overall structure is huge.

[0009] Therefore, how to design the end loading machine in the automatic swing arm trolley is of great significance for improving the utilization rate of the carriage space and ensuring the flexibility and stability of controlling the end loading machine during operation. Summary of the Invention

[0010] The purpose of the present disclosure is to address the above defects: design an end loading machine for an automatic swing arm trolley, which is applicable to different types of freight carriages, and at the same time has the characteristics of stable conveying, simple operation, and compact structure without occupying space.

[0011] To achieve the above purpose, in an embodiment of the present disclosure, an end loading machine for an automatic swing arm trolley is provided, including a telescopic conveying part provided on the automatic swing arm trolley along the goods conveying direction, and a connecting part connected to the end loading machine for controlling the swing of the end loading machine. The connecting part is movably connected to the telescopic conveying part, and the telescopic conveying part is connected to a direction-adjusting conveying device on the same conveying line through the connecting part. The connecting part includes a U-shaped plate and a joint gear assembly. The joint gear assembly is movably connected to the telescopic conveying part for controlling the direction-adjusting conveying device to swing upward or downward. The open end of the U-shaped plate is movably connected to the joint gear assembly, and the closed end is fixedly connected to the direction-adjusting conveying device for controlling the direction-adjusting conveying device to swing left or right. A steering boost conveying device that rotates along the same conveying line is connected to the direction-adjusting conveying device.

[0012] Through the above embodiments, the steering and conveying device connects the telescopic conveying part to the same conveying line through the U-shaped plate, and controls the telescopic conveying part to extend forward or retract backward along the cargo conveying direction, so as to adapt to the position in the dimension of the carriage length, so that the end loading machine can be stably conveyed along the direction of the carriage length to the stacking place when in use.

[0013] At the same time, the steering and conveying device is connected to the telescopic conveying part, and the steering boost conveying device is also rotatably connected to the steering and conveying device, and the steering and conveying device, the telescopic conveying part and the steering boost conveying device are all located on the same conveying line. Therefore, when the telescopic conveying part performs the action of extending forward or retracting backward, the steering and conveying device and the steering boost conveying device both move together, so that when the end loading machine works in the freight car carriage, it will not occupy the use space in the carriage due to the existence of a complex and variable conveying line, and the structures of the components of the end loading machine are distributed in a single linear manner, with a compact structure and a small overall volume, thereby further improving the utilization rate of the internal space of the carriage.

[0014] Drive the connecting part connected to the telescopic conveying part to move. When the articulated gear assembly movably connected to the telescopic conveying part moves, at this time, the steering and conveying device and the rotating boost device connected to the steering and conveying device move upward or downward.

[0015] When the U-shaped plate movably connected to the articulated gear assembly moves, at this time, the steering and conveying device fixedly connected to the closed end of the U-shaped plate moves left or right.

[0016] When the articulated gear assembly and the U-shaped plate move simultaneously, at this time, the steering and conveying device simultaneously moves upward or downward, left or right, so that the end loading machine is more flexible and variable during use.

[0017] In order to more completely and clearly present the core technical solution on the basis of the inventive concept, additional features are added to the core technical solution and further refinement is carried out. Therefore, there are also the following different embodiments:

[0018] In some embodiments, the telescopic conveying part includes a fixed conveying bracket, a linear driving mechanism, and a movable conveying bracket. The movable conveying bracket is connected to the fixed conveying bracket through the linear driving mechanism. On both sides of the movable conveying bracket, a first driving source, a second driving source, and a first transmission member are respectively provided. The first driving source is connected to one end of the articulated gear assembly through the first transmission member, and the second driving source is connected to the other end of the articulated gear assembly through the first transmission member. When the first driving source is driven, the articulated gear assembly moves upward or downward. When the second driving source is driven, the U-shaped plate moves left or right. When the first driving source and the second driving source are driven simultaneously, the articulated gear assembly moves upward or downward while the U-shaped plate also moves left or right.

[0019] Through the above embodiments, the articulated gear assembly is connected to the first driving source and the second driving source on both sides of the movable conveying bracket through the transmission member. When the articulated gear assembly is driven by the first driving source and / or the second driving source, the connecting part can achieve 8 different movement directions, so that the effect of multi-directional steering can be achieved, making the end loader more flexible during operation.

[0020] In some embodiments, the articulated gear assembly includes a shaft group and a bevel gear transmission box. The bevel gear transmission box is fixed on the shaft group. The two end parts of the bevel gear transmission box are movably connected to the U-shaped plate. The two ends of the shaft group are movably installed on the movable conveying bracket. One end of the shaft group is connected to the first driving source through the first transmission member for driving the bevel gear transmission box to move, and the other end of the shaft group is connected to the second driving source through the first transmission member for driving the U-shaped plate to move.

[0021] Through the above embodiments, the shaft group on the articulated gear assembly is fixedly connected to both sides of the gear transmission box, further ensuring the connection stability of the U-shaped plate connecting piece during the steering process.

[0022] In some embodiments, the direction-adjusting conveying device includes a first frame, two first conveying parts arranged side by side at a certain interval on the first frame, and a suction cup rotating mechanism arranged between the two first conveying parts. The adsorption surface of the suction cup rotating mechanism is in the same direction as the conveying surface of the first conveying part.

[0023] Through the above embodiments, when the goods are conveyed from the end of the production line or the indoor warehouse to the position where the orientation of the goods identification needs to be rotated and adjusted, it only needs to drive the suction cup rotating mechanism located between the two first conveying parts arranged side by side at a certain interval. Moreover, the adsorption force is large, and the goods can be firmly adsorbed and then rotated and adjusted. And the adsorption surface of the suction cup rotating mechanism is in the same direction as the conveying surface of the conveying part, so there is no need to worry about the problem of the goods falling, further increasing the stability during the process of rotating and adjusting the identification.

[0024] In some embodiments, the suction cup rotating mechanism includes a vacuum suction cup, a rotating shaft, and a lifting cylinder. A plurality of vacuum suction cups are connected to the lifting cylinder and are used to drive the vacuum suction cups to move upward or downward. The rotating shaft is connected to the lifting cylinder and is used to drive the vacuum suction cups to rotate.

[0025] Through the above embodiments, when the goods are conveyed to the orientation conveying device, the lifting cylinder is driven to move upward at this time, so that the adsorption surfaces of the plurality of vacuum suction cups connected to the lifting cylinder are in contact with the bottom surface of the goods. At this time, the lifting cylinder continues to move upward until the goods are lifted away from the conveying surface of the orientation conveying device. Then, the vacuum suction cups adsorb and fix the bottom of the goods. Next, the rotating shaft is driven to rotate, so that the lifting cylinder connected to the rotating shaft rotates together. At the same time, the vacuum suction cups connected to the lifting cylinder rotate the adsorbed and fixed goods together, thereby adjusting the orientation of the goods label by rotation, and improving the stability of the goods during rotation and orientation.

[0026] In some embodiments, hinge swing arms mounted on the first frame are provided on both sides of the suction cup rotating mechanism.

[0027] Through the above embodiments, after the orientation of the goods is adjusted by rotation, the hinge swing arms provided on both sides of the suction cup rotating mechanism will perform the action of clamping and straightening the goods, so as to further increase the stability of the end loader during subsequent conveying.

[0028] In some embodiments, the hinge swing arm includes a swinging portion, a driving mechanism, and a second transmission member. The second transmission member passes through the first frame. A driving mechanism is provided on the first frame. The swinging portions are two groups and are respectively arranged on both sides of the first frame. The driving mechanism is connected to the swinging portions through the second transmission member, so that the swinging portions on both sides swing synchronously and towards each other relative to the frame.

[0029] Through the above embodiments, the two swinging portions are respectively installed on the first frame, and the driving mechanism is connected to the swinging portions through the second transmission member. When the driving mechanism is driven, the swinging portions on both sides of the first frame move synchronously and towards each other, so as to prevent the goods from falling off both sides of the conveyor belt after rotation and orientation by the end loader, thereby further improving the stability of the end loader during the conveying process.

[0030] In some embodiments, the steering boost conveying device includes a second frame, a second conveying portion provided on the second frame along the conveying direction, a rotating and joint portion connected to one end of the second conveying portion opposite to the conveying direction, and a third driving source coaxially connected to the rotating joint portion. When the third driving source does not drive the rotating joint portion, the second frame is in a horizontal state. When the third driving source drives the rotating joint portion to rotate 90° clockwise or counterclockwise, the frame is in a vertical state.

[0031] Through the above embodiments, during the process of driving the rotating joint portion by the power source to rotate 90° clockwise or counterclockwise, the conveying portion coaxially connected to the rotating joint portion is fixed on the second frame, further making the structure of the steering boost conveying device compact. Thus, the second frame rotates with the rotating joint portion to achieve a horizontal or vertical state of motion, so that the goods on the second frame rotate together with the second frame, thereby realizing the synchronous flipping and orientation adjustment of the goods to adapt to different stacking methods.

[0032] In some embodiments, the second conveying portion includes a conveying structure and a suction cup mechanism. The suction cup mechanism is provided in two groups and symmetrically arranged on both sides of the conveying structure respectively, and the conveying structure is connected to one end of the rotating joint portion.

[0033] Through the above embodiments, before rotating and orienting the goods, the suction cup mechanism adsorbs and fixes the bottom of the goods, thereby preventing the goods from falling, and further improving the stability of the steering boost conveying device during the rotation and orientation adjustment.

[0034] In some embodiments, the conveying structure includes a boosting mechanism and a transporting mechanism. The boosting mechanism is provided in two groups and arranged on both sides of the transporting mechanism respectively, and the transporting mechanism and the boosting mechanism convey the goods on the second frame.

[0035] Through the above embodiments, with the change of the motion state of the second frame, the boosting mechanism and the transporting mechanism can work collaboratively, thereby further improving the stability of the steering boost conveying device during the conveying process.

[0036] In summary, compared with the prior art, when implementing the technical solution of the present disclosure, there are at least the following beneficial effects:

[0037] 1. It has the effect of good stability during use; in the first aspect, the telescopic conveying part is improved so that the telescopic conveying part, the direction-changing conveying device, and the steering boosting conveying device are arranged on the same conveying line. When the telescopic conveying part is driven to extend forward or retract backward along the cargo conveying direction, the direction-changing conveying device and the steering boosting conveying device can move together and can complete the conveying work of the cargo simultaneously during the movement of the telescopic conveying part. The cargo will not jolt during transportation and can be stably conveyed to the carriage stacking place.

[0038] In the second aspect, the connecting part is improved so that the shaft group of the articulated gear assembly is fixedly connected to both sides of the gear transmission box, thus ensuring the stability of the direction-changing conveying device during the swinging process.

[0039] In the third aspect, the suction cup rotating mechanism and the hinge swing arm of the direction-changing conveying device are improved to further increase the stability during the rotation adjustment marking process.

[0040] 2. It has the effect of good flexibility during use; the connecting part is improved so that the articulated gear assembly is connected with a first driving source and a second driving source, and different driving sources control different movements, so that the end loader is more flexible and changeable during use.

[0041] 3. It has the effect of improving the utilization rate of the internal space of the carriage during use; the steering boosting conveying device, the direction-changing conveying device, and the telescopic conveying part are connected on the same conveying line, and the structures of each component part are distributed in a single linear manner, making the structure of the end loader compact and the overall volume small. Therefore, during use, it will not occupy the internal use space of the carriage, thus improving the utilization rate of the internal space of the carriage. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] The following description provides many different embodiments, or examples, for implementing different features of the present disclosure. The elements and arrangements described in the following specific examples are only used to concisely express the present invention, which is only used as an example and is not intended to limit the present invention.

[0068] In addition, the "conveyor direction" mentioned throughout the text refers to the direction in which the goods are conveyed to the stacking area of the truck carriage. Since the position of the truck is not fixed, the "conveyor direction" can change according to the change in the position of the truck.

[0069] In addition, when words indicating directions such as "up", "down", "front", and "back" appear throughout the text, they are all described based on the positions shown in the drawings. This is only for the sake of simplifying the description and does not refer to a specific fixed position. Specifically, as shown in the attached Figure 1 figures, nouns such as "up", "down", "front", and "back" are all described based on the "conveyor direction" of the goods as the reference. Those skilled in the art can determine the "conveyor direction" of the goods according to the actual position of the truck, and further determine the installation or arrangement direction of each component. Therefore, all the nouns used to indicate directions throughout the text cannot be used to limit the present invention.

[0070] It should be noted that the "first", "second", and "third" that appear throughout the text all represent the serial numbers of the elements, used to mark elements with the same name, only for distinguishing different elements, rather than implying their importance.

[0071] Embodiment 1

[0072] Please refer to Figure 1 When the end loader conveys the goods located at the end of the production line or in the indoor warehouse to the truck carriage for stacking, it can greatly improve the space utilization rate of the truck carriage, and can be flexibly controlled and stably operated. In this embodiment, an end loader of an automatic swing arm trolley is provided. On the one hand, it includes a telescopic conveying part 1 arranged on the automatic swing arm trolley along the goods conveying direction. When the telescopic conveying part 1 is driven to move, it can extend forward or retract backward along the goods conveying direction, so as to adapt to the length dimension of the carriage and can be applied to truck carriages of different types of lengths.

[0073] On the other hand, it also includes a connecting part 2 for controlling the swing of the end loader. When the connecting part 2 of the automatic swing arm trolley is controlled, the end loader connected to the connecting part 2 realizes the swing.

[0074] Therefore, in order to ensure the flexibility of the end loader during operation, the connecting part 2 is further improved. The specific improvement method is to movably connect the connecting part 2 to the telescopic conveying part 1, and the telescopic conveying part 1 is connected with a direction-adjusting conveying device 3 on the same conveying line through the connecting part 2. The connecting part 2 mainly includes two parts: a U-shaped plate 201 and a knuckle gear assembly 202.

[0075] First, the knuckle gear assembly 202 is movably connected to the telescopic conveying part 1. When the telescopic conveying part 1 is controlled, the knuckle gear assembly 202 movably connected to the telescopic conveying part 1 is driven to rotate, so that the direction-adjusting conveying device 3 realizes upward or downward swing.

[0076] Secondly, the open end of the U-shaped plate 201 is movably connected to the knuckle gear assembly 202, and the closed end is fixedly connected to the direction-adjusting conveying device 3. When the U-shaped plate 201 is controlled, the U-shaped plate 201 movably connected to the knuckle gear assembly 202 moves along the direction perpendicular to the movement direction of the knuckle gear assembly 202. At this time, the U-shaped plate 201 shows left or right movement along the goods conveying direction. At the same time, the direction-adjusting conveying device 3 fixed on the U-shaped plate 201 realizes left or right swing.

[0077] Finally, a steering boost conveying device 4 rotating along the same conveying line is connected to the direction-adjusting conveying device 3. When the goods are conveyed on the direction-adjusting conveying device 3, they will first go through the direction-adjusting process to realize the direction adjustment of the outer package label of the goods, so that the outer packages of the goods finally stacked on the truck carriage face the same direction. After the label orientation of the goods is adjusted, when they are conveyed to the steering boost conveying device 4, the steering boost conveying device 4 is driven to rotate, and the goods on the steering boost conveying device 4 realize the direction change, so as to adapt to different stacking methods.

[0078] Embodiment 2

[0079] Please refer to Figure 1 , Embodiment 2 is based on Embodiment 1, and further refinement and specific implementation manners of the telescopic conveying part 1 are carried out from two aspects of structural composition and motion state.

[0080] In terms of the structural composition of the telescopic conveying part 1: The telescopic conveying part 1 mainly includes three parts: a fixed conveying bracket 101, a linear driving mechanism 102, and a movable conveying bracket 103. Among them, the movable conveying bracket 103 is connected to the fixed conveying bracket 101 through the linear driving mechanism 102, and a first driving source 5, a second driving source 6, and a first transmission member 7 are respectively arranged on both sides of the movable conveying bracket 103. Among them, the first driving source 5 is connected to one end of the articulated gear assembly 202 through the first transmission member 7, and the second driving source 6 is connected to the other end of the articulated gear assembly 202 through the first transmission member 7.

[0081] In terms of the motion state realized by controlling the telescopic conveying part 1: On the first aspect, driving the linear driving mechanism 102 on the telescopic conveying part 1 to work, so that the movable conveying bracket 103 extends forward or retracts backward along the fixed conveying bracket 101 under the drive of the linear driving mechanism 102. Through the telescopic process of the telescopic conveying part 1, when adapting to the conveyance of goods along the stacking direction of the freight car, it can adapt to the lengths of different types of freight car carriages.

[0082] On the second aspect, when driving the first driving source 5 installed on one side of the movable conveying bracket 103 on the telescopic conveying part 1, the articulated gear assembly 202 moves upward or downward.

[0083] When driving the second driving source 6 installed on the other side of the movable conveying bracket 103 on the telescopic conveying part 1, the U-shaped plate 201 moves left or right.

[0084] When simultaneously driving the first driving source 5 and the second driving source 6 installed on the movable conveying bracket 103 on the telescopic conveying part 1, the articulated gear assembly 202 moves upward or downward while the U-shaped plate 201 also moves left or right.

[0085] Embodiment 3

[0086] Please refer to Figures 2 to 3 , Embodiment 3 is based on Embodiment 2, and further refinement and specific implementation manners of the articulated gear assembly 202 are carried out, where the articulated gear assembly 202 mainly includes two parts: a shaft group 2021 and a bevel gear transmission box 2022.

[0087] First, to ensure the structural stability of the joint gear assembly 202 during operation and further improve the stability of the end loader during operation, the bevel gear transmission case 2022 is fixed on the shaft group 2021, and a second transmission shaft 20221 is provided inside the bevel gear transmission case 2022. Bevel gears are installed at both ends of the second transmission shaft 20221, and the second transmission shaft 20221 passes through both ends of the bevel gear transmission case 2022 and is movably connected to the U plate 201.

[0088] Secondly, both ends of the shaft group 2021 are movably installed on the movable conveying bracket 103. One end of the shaft group 2021 is connected to the first drive source 5 through the first transmission member 7. When the first drive 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 case 2022 fixed on the shaft group 2021 to rotate together, so that the entire bevel gear transmission case 2022 moves upward or downward under the push of the first drive source 5.

[0089] And a first transmission shaft 20211 is sleeved inside the other end of the shaft group 2021. The first transmission shaft 20211 can rotate inside the shaft group 2021, and a bevel gear is installed at one end of the first transmission shaft 20211.

[0090] During installation, the bevel gears installed on the first transmission shaft 20211 and the second transmission shaft 20221 are perpendicularly meshed with each other inside the bevel gear transmission case 2022, and the first transmission shaft 20211 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 first transmission shaft 20211 through the first transmission member 7, causing the first transmission shaft 20211 to rotate. At this moment, the bevel gears on the first transmission shaft 20211 and the second transmission shaft 20221 perform meshing transmission, thereby driving the second transmission shaft 20221 to rotate.

[0091] At this time, the U plate 201 connected to the bevel gear transmission case 2022 through the second transmission shaft 20221 moves left or right relative to the bevel gear transmission case 2022.

[0092] In addition, the first transmission member 7 can be a synchronous belt or a connecting rod, so the shaft group 2021 can be connected to the first drive 5 and the second drive source 6 by means of a synchronous belt or a connecting rod.

[0093] Embodiment 4

[0094] Please refer to Figure 4, Embodiment 4 is based on Embodiment 1 and further details and specific implementation of the direction-changing conveying device 3. The direction-changing conveying device 3 mainly includes three parts: a first frame 301, two first conveying parts 302 arranged side by side at intervals on the first frame 301, and a suction cup rotating mechanism 303 arranged between the two first conveying parts 302. To ensure reliable conveying of goods at the end loading machine, the adsorption surface of the suction cup rotating mechanism 303 is oriented the same as the conveying surface of the first conveying part 302.

[0095] Embodiment 5

[0096] Please refer to Figure 5 , Embodiment 5 is based on Embodiment 4 and further details and specific implementation of the suction cup rotating mechanism 303. The suction cup rotating mechanism 303 includes a first vacuum suction cup 3031, a rotating shaft 3032, and a lifting cylinder 3033.

[0097] First, several first vacuum suction cups 3031 are connected to the lifting cylinder 3033. When the lifting cylinder 3033 is driven, the lifting cylinder 3033 moves upward or downward to reset. At the same time, several first vacuum suction cups 3031 connected to the lifting cylinder 3033 move together with the lifting cylinder 3033, thus realizing the upward or downward movement of the first vacuum suction cup 3031.

[0098] Second, 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, and at this moment, the first vacuum suction cup 3031 connected to the lifting cylinder 3033 rotates.

[0099] Embodiment 6

[0100] Please refer to Figure 4 , Embodiment 6 is based on Embodiment 5 and further improves and details the layout around the suction cup rotating mechanism 303. To ensure that after the process of selective loading and direction-changing, the goods do not deviate from the conveying center position, which may cause the phenomenon of box dropping during subsequent conveying. Hinge swing arms 8 are installed on both sides of the suction cup rotating mechanism 303 on the first frame 301. When the goods pass through the end loading machine and the identification is rotated and adjusted to face the correct direction, the hinge swing arms 8 on both sides of the suction cup rotating mechanism 303 move to clamp and straighten the goods after the rotation and adjustment of the identification, so as to ensure that the goods can be conveyed normally along the conveying center.

[0101] Embodiment 7

[0102] Please refer to Figure 6, in this Embodiment 7, on the basis of Embodiment 6, the hinge swing arm 8 is further refined and the specific implementation manners are elaborated. The hinge swing arm 8 includes three parts: a swing portion 801, a driving mechanism 802, and a second transmission member 803.

[0103] First, in terms of the connection relationships of the structures of the hinge swing arm 8: the second transmission member 803 passes through the first frame 301, the driving mechanism 802 is provided on the first frame 301, two groups of swing portions 801 are respectively arranged on both sides of the first frame 301, and the driving mechanism 802 is connected to the swing portions 801 through the second transmission member 803, so that the swing portions 801 on both sides swing synchronously and towards each other relative to the first frame 301.

[0104] To avoid interference between components during the force transmission to the swing portion 801 and affect the working stability of the swing portion 801, the second transmission member 803 is installed by passing through the relief hole provided on the first frame 301. The second transmission member 803 can be in the form of belt drive, or in the form of chain drive, or in the form of link drive. Specifically, it can be in the form of belt drive, and the type of the belt is a synchronous belt.

[0105] Secondly, in terms of the working principle of the hinge swing arm 8: when the goods on the end loader are rotated and then conveyed to a position close to the driving mechanism 802, the driving mechanism 802 is driven at this time, and the force is transmitted to the swing portions 801 on both sides of the first frame 301 through the second transmission member 803, so that the swing portions 801 move synchronously and towards each other to straighten and reset the goods after rotation, thereby preventing the goods from falling during the subsequent conveying process.

[0106] Embodiment 8

[0107] Please refer to Figure 7 , in this Embodiment 8, on the basis of Embodiment 1, the steering boost conveying device 4 is further refined and the specific implementation manners are elaborated from two aspects: the structural composition and connection relationships of the steering boost conveying device 4, and the motion state of the steering boost conveying device 4.

[0108] In the first aspect, regarding the structures and connection relationships of the steering boost conveying device 4: The steering boost conveying device 4 includes 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 one end of the second conveying part 402 opposite to the conveying direction. The rotating joint part 403 is coaxially connected to a third driving source 9. Thus, the overall structure of the steering boost conveying device 4 is more compact, with a small volume ratio, so that the overall structure of the end loader is smaller, enabling it to occupy less space inside the carriage when the end loader is working, thereby further improving the utilization rate of the space inside the carriage.

[0109] In the second aspect, regarding the motion state of the steering boost conveying device 4, when the third driving source 9 does not drive the rotating joint part 403, at this time, 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 on the steering boost conveying device 4 are conveyed in the initial placement direction.

[0110] 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 boost conveying device 4 is in a vertical state relative to the conveying surface of the steering adjustment conveying device 3. At this moment, the goods on the steering boost conveying device 4 are conveyed in a direction perpendicular to the original placement direction.

[0111] Embodiment 9

[0112] This Embodiment 9 is based on Embodiment 8, further refining the second conveying part 402 and elaborating on the specific implementation manner. For details, please refer to Figures 8 to 11 .

[0113] The second conveying part 402 mainly includes a conveying structure 4021 and a suction cup mechanism 4022. Two sets of suction cup mechanisms 4022 are provided, and the two sets of suction cup mechanisms 4022 are symmetrically arranged on both sides of the conveying structure 4021 respectively, so that before the goods are conveyed and redirected on the conveying structure 4021, the suction cup mechanisms 4022 on both sides can adsorb and fix the bottom of the goods.

[0114] Furthermore, in order to ensure that the suction cup mechanism 4022 firmly adsorbs the goods on the conveying structure 4021 and prevent the goods from falling, the conveying surface of the conveying structure 4021 is higher than the adsorption surface of the suction cup mechanism 4022. Due to the height difference between the conveying surface and the adsorption surface, it is convenient to realize the upward lifting action of the suction cup mechanism 4022. During the upward lifting process of the suction cup mechanism 4022, the adsorption surface of the suction cup mechanism 4022 is in close contact with the bottom of the goods, so as to further ensure that the goods can be firmly adsorbed without falling.

[0115] Next, connect the conveying structure 4021 to one end of the rotating joint part 403. When driving the rotating joint part 403 to rotate, it drives the conveying structure 4021 to rotate.

[0116] Among them, the conveying structure 4021 mainly includes two parts: a boosting mechanism 40211 and a transporting mechanism 40212. There are two groups of boosting mechanisms 40211, which are respectively arranged on both sides of the transporting mechanism 40212. The suction cup mechanism 4022 includes a second vacuum suction cup 40221, a lifting component 40222, a lifting guide rod 40223, a moving plate 40224, and a moving guide rod 40225. For details, please refer to Figure 11 .

[0117] When driving the rotating joint part 403 to rotate clockwise or counterclockwise by 90°, the second frame 401 is in a vertical state. At this time, the boosting mechanism 40211 and the suction cup mechanism 4022 work together to convey the adsorbed and fixed goods to the stacking place in a direction perpendicular to the initial placement position. For details, please refer to Figure 12 .

[0118] Specifically, first, before the rotating joint part 403 rotates, it is necessary to adsorb and fix the goods on the conveying structure 4021. Therefore, one end of the lifting guide rod 40223 is vertically installed on the moving plate 40224, and the other end is connected to the second vacuum suction cup 40221. A lifting component 40222 is connected between the second vacuum suction cup 40221 and the moving plate 40224, so that when driving the lifting component 40222, the second vacuum suction cup 40221 moves upward under the guidance of the lifting guide rod 40223 until it moves into close contact with the bottom of the goods. At this time, compressed air is connected to the vacuum generator connected to the second vacuum suction cup 40221, and the compressed air is converted to make the second vacuum suction cup 40221 have an adsorption force to adsorb the bottom of the goods.

[0119] Secondly, then convey the adsorbed and fixed goods along the conveying direction. At this time, the moving plate 40224 is slidably connected to the moving guide rod 40225, so that the moving plate 40224 can move forward or backward on the moving guide rod 40225. When the moving guide rod 40225 is driven to move forward, the second vacuum suction cup 40221 connected to the moving guide rod 40225 through the lifting guide rod 40223 conveys the adsorbed and fixed goods along the conveying direction.

[0120] Meanwhile, drive the boosting mechanism 40211 to move forward again. The boosting mechanism 40211 includes two parts, namely a scraper 4021111 and a boosting conveying mechanism 402112. A number of scrapers 402111 are provided on the boosting conveying mechanism 402112.

[0121] Further, coaxially connect the boosting conveying mechanisms 40112 on both sides of the conveying mechanism 40212, and make the positions of the scrapers 402111 on both sides of the conveying mechanism 40212 opposite to each other. Thus, when the boosting conveying mechanism 402112 is driven, the scrapers 402111 provided on the boosting conveying mechanism 402112 can move synchronously, so that when the scrapers 402111 hold both sides of the goods, the forces received on both sides of the goods are balanced, thereby scraping off the goods adsorbed and fixed on the second vacuum suction cup 40221, and finally completing the entire process of adsorption, fixation - rotation and orientation adjustment - conveying and scraping off of the goods.

[0122] When the rotating joint part 403 is not driven to rotate, the second rack 401 is in a horizontal state at this time, and the suction cup mechanism 4022 does not work at this time. The conveying mechanism 40212 and the boosting mechanism 40211 mainly move synchronously. The conveying mechanism 40212 mainly includes a conveyor belt 402122 and conveying rollers 402121. The conveyor belt 402122 is sleeved on the conveying rollers 402121. When the conveying rollers 402121 are driven to rotate, the conveyor belt 402122 conveys along the conveying direction to convey the goods in the initial placement position. For details, please refer to Figure 14 。

[0123] Therefore, the goods after being turned on the second conveying part 402 can be directly conveyed to the carriage for stacking without changing the working station again, without adding an additional conveying line or clamping device on the end loading machine, thereby further simplifying the overall structure of the end loading machine, reducing the volume ratio during the operation of the end loading machine in the internal space of the carriage, and achieving the purpose of improving the space utilization rate of the internal space of the carriage.

[0124] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
