Description

Technical Field

[0001] The invention relates to the field of logistics mechanical equipment, and in particular to an automatic loading device for trucks. Background Art

[0002] With the improvement of modern mechanization and the popularization of unmanned factories and smart factories, more and more companies are adopting automated storage, management and turnover of goods, which can improve space utilization and management efficiency and reduce labor costs.

[0003] However, when it comes to the turnover of goods, the existing turnover method still uses the traditional turnover method. For example, when loading goods for transportation, manual handling and loading are still used. This method has low work efficiency, poor safety, high labor costs for enterprises, and is difficult to connect with automated equipment. In view of this, it is particularly important to develop and design an automatic loading system that can solve the above problems.

[0004] For example, a bagged material loading system in the prior art (patent application number: CN201922284092.1) includes a laser vision system, a conveying system, a robot system and a control system. The robot system includes a six-axis industrial robot, a walking guide rail and a robot fixture set on the six-axis industrial robot. The industrial robot is set on the walking guide rail. The industrial robot is set at the end of the conveying system to load the bagged materials on the conveying system. The laser vision system includes two sets of line laser sensors installed on the ground fixed bracket and two sets of point laser sensors installed on the robot's six-axis end fixture. The line laser sensor and the point laser sensor are connected to the control system in communication. The control system receives information from the laser vision system and controls the conveying system and the robot system to realize the automatic loading of materials. The loading system can realize the automatic loading and stacking of materials, simplifying the requirements for manual control. However, when loading, the loading system can only load a small amount of materials at a time, and can only grab three bags of materials for loading each time; and the loading system uses a robot system for grabbing and loading, which is mainly aimed at loading bagged materials, and cannot be adapted to the loading of more materials in different packaging forms; and when the system uses a smaller robot system, its reliability is insufficient when grabbing heavier goods, but if a larger robot system is used, there will be problems such as high cost and a large overall footprint of the system; the loading system cannot be adapted to vehicles of various sizes. If the vehicle is too small, the robot system will easily lead to reduced accuracy in placing the goods when loading; if the vehicle is too large, the robot system will have goods that cannot be loaded into the vehicle when loading. Summary of the invention

[0005] In order to solve the above problems, the primary purpose of the present invention is to provide an automatic loading device, which can more accurately place the goods into the truck during loading, so that the goods can be placed more neatly in the truck.

[0006] Another object of the present invention is to provide an automatic loading device, which can load goods of different packages, different sizes and different weights into a truck.

[0007] Another object of the present invention is to provide an automatic loading device, which can be adapted to trucks of different sizes, making the loading device easier to promote.

[0008] In order to achieve the above object, the technical solution of the present invention is as follows.

[0009] An automatic loading device, characterized in that the loading device includes a loading mechanism for pushing goods into a truck, a conveying device for conveying goods, and a position adjustment mechanism for adjusting the angle between the conveying device and the loading mechanism, the loading mechanism is connected to the conveying device, a loading position for placing the goods to be pushed is provided on the loading mechanism, and a loading path for transporting goods to the loading position to push the goods into the truck is formed from the conveying device to the loading mechanism; the loading mechanism and the conveying device are both connected to the position adjustment mechanism, so that the position adjustment mechanism can adjust the angle between the loading mechanism and the conveying device. In the loading device, the goods are transported to the loading mechanism by the conveying device, and the goods are pushed into the truck by the loading mechanism; the conveying device can be an advance and retreat conveying device to realize retractable transportation, and can drive the loading mechanism to move forward and backward when the goods are transported to the loading mechanism, so that the loading mechanism can move in the truck, and then the loading mechanism can better load the goods into the truck. In the loading device, the loading mechanism pushes the goods into the truck, so that it can adapt to the loading of goods of different packages, different sizes and different weights; to solve the problem of the prior art that the goods are restricted by the shape and weight of the goods due to the clamping loading; and when the loading mechanism pushes the goods for loading, the angle between the loading mechanism and the conveying device is adjusted based on the position adjustment mechanism, and the angle between the loading mechanism and the truck can be adjusted. When there is a certain inclination between the conveying device and the truck (the space in the truck cargo box for loading goods), the goods can be accurately placed in the truck, so that the goods are neatly stacked in the truck. The conveying device is a prior art, such as a structure preferably for conveying by a conveyor belt, or a structure for conveying by a roller.

[0010] Furthermore, telescopic supporting feet with supporting functions are fixedly arranged under the conveying device and the loading mechanism, and a telescopic motor is arranged in the telescopic supporting feet to drive the telescopic supporting feet to extend and retract. The arrangement of the telescopic supporting feet makes the conveying device and the loading mechanism more stable when transporting or grabbing goods, and can carry heavier objects for transportation, grabbing or pushing and loading. The telescopic supporting feet are retractable, so that when the loading mechanism is extended into the truck driven by the conveying device, the corresponding telescopic supporting feet are shortened to avoid blocking the loading mechanism from entering the truck, and can adapt to the bottom surface of the truck, so that the loading mechanism can also be supported by the telescopic supporting feet in the truck. The principle of the arrangement in which the telescopic motor drives the telescopic supporting feet to extend and retract is the prior art, such as being realized by a telescopic motor and a screw rod.

[0011] Furthermore, the loading mechanism is provided with a first sensor assembly for detecting a specific position of the loading mechanism in the truck.

[0012] Furthermore, the loading mechanism is also provided with a second sensor assembly for detecting the position of the truck so that the loading mechanism can smoothly enter the truck. The second sensor assembly is preferably composed of two sensors, which are used to scan the length, width and height of the truck cargo box where the truck is located, and obtain the approximate outline of the cargo box so that the loading mechanism can smoothly enter the truck, and after the loading mechanism enters the truck, the position of the loading mechanism is fine-tuned through the subsequent first sensor assembly. The two sensors of the second sensor assembly are set in the prior art.

[0013] Furthermore, the first sensor assembly includes two transverse sensors and two longitudinal sensors, the two transverse sensors are respectively arranged on both sides of the loading mechanism, and the two longitudinal sensors are respectively arranged at both ends of the front side of the loading mechanism. The arrangement of the two longitudinal sensors and the two transverse sensors enables the loading mechanism to know the distance between its left and right sides and the inner side surfaces of the left and right sides of the truck and the specific distance between its front end and the inner side surface of the front side of the truck, as well as the tilt degree of the loading mechanism in the truck; thus, it can help adjust the position and tilt degree of the loading mechanism in the truck.

[0014] Furthermore, the loading mechanism includes a loading component for pushing the goods into the truck, a buffer adjustment component for receiving the goods delivered by the conveying device and adjusting the position of the goods, and a buffer pushing component for pushing the goods on the buffer adjustment component to the loading component; the loading position is located on the loading component, the buffer adjustment component is connected with the conveying device, the loading component is connected with the buffer adjustment component, and the buffer pushing component is fixedly arranged on the buffer adjustment component. The setting of the buffer adjustment component can adjust the position of the goods delivered from the conveying device, and then push the goods with adjusted position to the loading component through the buffer pushing component, and the goods are preliminarily leveled when the buffer pushing component pushes the goods to the loading component; so that the further pushing of the goods by the loading component can push the goods into the truck more neatly.

[0015] Furthermore, the conveying device is radially arranged, and a buffer belt for transporting goods is transversely arranged on the buffer adjustment component, and one side of the buffer belt is connected to the conveying device; the buffer pusher component is located on one side of the buffer belt, and the loading component is located on the other side of the buffer belt. After the goods on the conveying device radially enter the buffer belt in sequence, the goods move transversely along the buffer belt, and the goods placed in a row transversely are pushed to the loading component by the buffer pusher component; this design allows individual goods to be adjusted into a row for pushing, so that a row of goods can be pushed at a time, and the number of goods pushed at a single time is greater, making the cargo loading efficiency higher.

[0016] Furthermore, the buffer pushing assembly includes more than two buffer pushing cylinders, the more than two buffer pushing cylinders are fixedly arranged on the buffer adjustment assembly, and the output shafts of the more than two buffer pushing cylinders are provided with buffer pushing parts, and the more than two buffer pushing parts are located on one side of the buffer belt. The arrangement of more than two pushing cylinders can make the pushing of goods more accurate.

[0017] Further, the buffer adjustment assembly includes a buffer adjustment body and a buffer belt telescopic part, the buffer belt telescopic part is movably arranged at one end of the buffer adjustment body, the buffer belt is arranged on the buffer adjustment body and the buffer belt telescopic part, and the buffer belt telescopic part is moved on the buffer adjustment body to adjust the length of the buffer belt between the buffer belt telescopic part and the buffer adjustment body for driving the movement of goods; the buffer belt telescopic part is movably arranged at one end of the buffer adjustment body through a slide rail slider structure. More than one buffer push cylinder is fixedly arranged on the buffer belt telescopic part. More than one buffer push cylinder is fixed on the buffer belt telescopic part, and can move with the movement of the buffer belt telescopic part. After the length of the buffer belt used for conveying goods increases, it can also correspond to one end of the buffer belt to push goods; and the adjacent parts of the two or more buffer push parts are overlapped to adapt to the buffer belt. The activity between the buffer adjustment body and the buffer belt telescopic part can increase the length of the buffer belt used for conveying goods, so as to increase the number of goods that can be accumulated on the buffer belt, so as to control the number of goods pushed and loaded each time. The buffer belt is specifically a conveyor belt. The movement between the buffer adjustment body and the buffer belt telescopic member can be adjusted manually or by using a cylinder or a motor.

[0018] Furthermore, the cache adjustment body is provided with a first cache roller and a second cache roller, the cache belt telescopic member is provided with a third cache roller and a fourth cache roller, the cache belt is movably provided on the first cache roller, the third cache roller, the second cache roller and the fourth cache roller in sequence, the first cache roller and the third cache roller are located in the same plane and the cache belt between the two is the part used to transport goods, the cache belt passes through the third cache roller, obliquely passes around the fourth cache roller downward, and then obliquely passes around the second cache roller downward. That is, the cache belt is sleeved on the first cache roller, the second cache roller, the third cache roller and the fourth cache roller, because of the relative movement between the cache adjustment body and the cache belt telescopic member, the length of the cache belt between the first cache roller and the third cache roller can be increased, while the length of the cache belt between the second cache roller and the fourth cache roller can be correspondingly reduced. The drive of the cache belt is the existing technology, such as using a motor or other structure to drive the rotation.

[0019] Furthermore, a cache connection component for grabbing the goods conveyed by the conveying device to the cache belt is also provided between the cache adjustment component and the conveying device; the cache connection component includes two cache clamping members, and the two cache clamping members are movably arranged on both sides of the conveying device to clamp the goods on the conveying device and drive them to the cache belt; the cache connection component also includes two cache connection motion cylinders, two cache connection motion members and two cache clamping cylinders, and the two cache connection motion cylinders, two cache connection motion members and two cache clamping cylinders are also respectively arranged on both sides of the conveying device; the cache connection motion cylinder is fixedly connected to the conveying device, the cache connection motion member is movably connected to the conveying device through a slide rail slider structure, the cache clamping cylinder is fixedly arranged on the cache connection motion member, the cache clamping member is fixedly arranged on the output shaft of the cache clamping cylinder, and the cache connection motion member is fixedly arranged on the output shaft of the cache connection motion cylinder. The setting of the cache connection assembly makes it more convenient to transport goods from the conveying device to the cache adjustment assembly. The two cache clamping cylinders drive the two cache clamping parts to clamp the goods, and the two cache connection moving cylinders simultaneously drive the two cache connection moving parts to move, so that the goods are clamped by the two cache clamping parts to the cache adjustment assembly.

[0020] Furthermore, the loading component includes a loading cache component for lateral transportation of the goods pushed from the cache adjustment component to accumulate the goods, and is used to push the goods on the loading cache component to the loading and pushing component in the truck when the goods on the loading cache component accumulate to a certain extent; the loading position is located on the loading cache component, the loading and pushing component is fixedly arranged on the loading cache component and corresponds to the loading position, and the loading cache component and the cache adjustment component can be slidably connected up and down; the loading component also includes a loading movable component, the loading movable component is fixedly arranged on the cache adjustment component, and the loading movable component is fixedly connected to the loading cache component, and is used to drive the loading cache component to move on the cache adjustment component; the loading cache component and the cache adjustment component are movably connected through a slide rail slider structure. The implementation principle of the loading movable component is the existing technology, such as using a cylinder or a motor to drive the loading cache component to move on the cache adjustment component. The setting of the loading cache component is that when the goods at the cache adjustment component are pushed to the cache adjustment component, the goods are transported and accumulated horizontally so that multiple goods can be pushed at a single time; specifically, although the loading cache component and the cache adjustment component both transport goods horizontally, the transportation directions of the two are opposite; when the goods are transported to one end of the cache adjustment component, a cache pushing piece pushes the goods to the loading cache component, and transports the goods in the other direction of the loading cache component, and after the goods on the loading cache component are accumulated enough, the loading pushing piece pushes the goods to the truck; while the loading pushing piece pushes the goods, the goods continue to be transported on the cache adjustment component, at this time the cache pushing piece does not push the goods, and the goods accumulate on the cache adjustment component; when the loading pushing piece completes pushing the goods, two or more cache pushing pieces push the goods at the same time, and all the accumulated goods are pushed to the loading cache component, and then a cache pushing piece continues to deliver a single good to the loading cache component.

[0021] The loading cache component and the cache adjustment component can be connected in a sliding manner up and down, so that the loading cache component can be moved up and down to adjust its position so as to load goods at different heights in the truck, so as to facilitate the stacking of goods in multiple layers in the truck; and the loading movable component can automatically drive the loading cache component to move on the cache adjustment component.

[0022] Furthermore, the loading assembly further includes a loading slide plate, the buffer adjustment assembly is connected to one side of the loading buffer assembly, the loading slide plate is connected to the other end of the loading buffer assembly, and the loading slide plate is tilted.

The setting of the first loading cache component, the second loading cache component and the third loading cache component can expand the width of the loading cache component so that the loading cache component can push more goods at one time. The movement between the first loading cache component, the second loading cache component and the third loading cache component can be manually controlled or driven by a motor or a cylinder. The setting of the first loading cache component, the second loading cache component and the third loading cache component, combined with the setting of the cache adjustment body and the cache belt telescopic part, can adapt to trucks of different sizes, which is more convenient for promotion.

[0024] Furthermore, the first loading cache assembly, the second loading cache assembly and the third loading cache assembly are all provided with a plurality of rollers, and the first loading cache assembly, the second loading cache assembly and the third loading cache assembly are all provided with roller driving belts for driving the rollers to rotate. The principle of belt driving the rollers is the prior art.

[0025] Furthermore, the cargo loading and pushing assembly includes a cargo loading and pushing board and a cargo loading and pushing driving assembly, wherein the cargo loading and pushing board is arranged on the cargo loading and pushing driving assembly, and the cargo loading and pushing board pushes the cargo into the truck under the drive of the cargo loading and pushing driving assembly.

The loading push plate is covered on the loading push driving assembly before the oblique push plate pushing cylinder is pushed to prevent it from causing obstruction to the buffer pushing assembly when pushing goods. When the oblique push plate pushing cylinder is pushed, the loading push plate assembly stands up until it is vertically on the loading push driving assembly. At this time, the radial push plate pushing cylinder output shaft extends out to fix the position of the loading push plate assembly, so that the loading push driving assembly pushes the loading push plate to push the goods.

[0027] Furthermore, the position adjustment mechanism includes a first adjustment component and a second adjustment component, one end of the first adjustment component and one end of the second adjustment component are respectively hingedly arranged on both sides of the conveying device, the other end of the first adjustment component and the other end of the second adjustment component are both hinged on the loading mechanism, the loading mechanism is movably connected to the conveying device, and the first adjustment component and the second adjustment component control and adjust the angle between the loading mechanism and the conveying device.

[0060] Working process: 1) Preparation work, the advance and retreat conveying device drives the loading device to extend into the truck, and the corresponding telescopic supporting feet on the loading device and the advance and retreat conveying device are shortened to adapt to the truck; two lateral sensors and two longitudinal sensors detect to determine the position of the loading mechanism in the truck (which also determines the width of the truck) and the degree of inclination; the position adjustment mechanism adjusts the position between the loading mechanism and the advance and retreat conveying device according to the degree of inclination of the loading mechanism in the truck; the cache adjustment component adjusts the length of the cache belt used to transport goods through the movement between the cache adjustment body and the cache belt telescopic part to adapt to the width in the truck; the loading cache component is extended through the relative movement between the first loading cache component, the second loading cache component and the third loading cache component to correspond to the cache adjustment component and adapt to the width in the truck.

[0061] When it starts working, the cargo grabbing mechanism grabs the piled cargo and continuously puts the cargo onto the first-level cargo conveyor belt. The first-level cargo conveyor belt conveys the cargo to the second-level cargo conveyor belt. Since the transportation speed of the first-level cargo conveyor belt is lower than that of the second-level cargo conveyor belt, the distance between the cargoes is widened after entering the second-level cargo conveyor belt. The cargoes enter from the side of the advance and retreat conveyor device under the transportation of the second-level cargo conveyor belt, and are driven to the cache connection component by the advance and retreat conveyor device. The cache connection component grabs the cargoes and places them on the cache belt, so that the cargoes are transported from longitudinal direction to transverse direction. The cargoes are driven by the cache belt to move to one side of the cache belt. When the cargoes are transported to the cache belt, When the goods are transported to one end of the belt, a cache pusher pushes the goods to the loading cache component and transports them in the other direction by the loading cache component; when the goods on the loading cache component are accumulated enough, the loading pushing component pushes the goods to the truck; when the loading pushing component is pushing the goods, the goods continue to be transported on the cache belt, and the cache pusher does not push the goods at this time, and the goods are accumulated on the cache adjustment component; when the loading pushing component completes pushing the goods, two or more cache pushers push the goods at the same time, and all the accumulated goods are pushed to the loading cache component, and then a cache pusher continues to deliver a single goods to the loading cache component; the above process of pushing goods continues, and the goods are continuously pushed to the truck. Specifically, each time the loading and pushing component pushes the goods, a row of goods can be placed in the truck; and the loading cache component can move upward on the cache adjustment component, so that when the loading and pushing component pushes the goods on the loading cache component next time, the goods can be placed on top of the goods placed last time, thereby achieving stacking; and when the goods at this position are already stacked full, the forward and backward conveying device drives the loading device backward and continues to push and stack the goods, so that all the goods are finally stacked in the truck.

[0062] The beneficial effect of the present invention is that, compared with the prior art, in the present invention, the goods are transported to the loading mechanism by the conveying device, and the goods are pushed into the truck by the loading mechanism; the conveying device can be an advance and retreat conveying device to realize retractable transportation, and can drive the loading mechanism to move forward and backward when the goods are transported to the loading mechanism, so that the loading mechanism can move in the truck, and then the loading mechanism can better load the goods into the truck. In the loading device, the setting of pushing the goods into the truck by the loading mechanism makes it adaptable to the loading of goods of different packages, different sizes and different weights; to solve the problem of the shape and weight restrictions of the goods caused by the clamping loading in the prior art; and when the loading mechanism pushes the goods for loading, the angle between the loading mechanism and the conveying device is adjusted based on the position adjustment mechanism, and the angle between the loading mechanism and the truck can be adjusted. When there is a certain inclination between the conveying device and the truck (the space for loading in the truck cargo box), the goods can also be accurately put into the truck, so that the goods are neatly stacked in the truck. The conveying device is a prior art, such as a structure that preferably conveys via a conveyor belt, or a structure that conveys via a roller.
