Description

Technical Field

[0001] This utility model relates to the field of automatic loading technology, and more specifically to an automatic loading machine for material packages. Background Technology

[0002] In chemical and grain processing plants, after products are processed, bagged, and then loaded onto trucks for transportation, the current practice is generally to use forklifts to transport goods to the trucks, then manually move the goods into the trucks and stack them neatly layer by layer. This operation is time-consuming and labor-intensive, and can significantly increase the workload for workers, especially in harsh environments, presenting certain drawbacks. With the continuous development of automation, automated loading machines have now replaced manual labor in directly transporting and stacking goods into trucks, greatly improving the efficiency of loading bagged goods and reducing labor costs.

[0003] However, the inventors discovered that currently common automatic loading machines have the following technical problems to varying degrees: 1. Some loading machines have a high degree of automation but complex structures and high investment costs, making them unsuitable for large-scale promotion; 2. Some loading machines have simple structures and low prices but low automation levels, still requiring manual assistance for loading and placement; 3. Some loading robots use rigid grippers to pick up and transfer packaging bags to transport vehicles, but rigid grippers are prone to tearing packaging bags, resulting in significant material loss, and packaging bags are also prone to falling off during the gripping process; 4. Some equipment can only load open trucks, making it difficult to meet the loading requirements of box trucks and to achieve orderly stacking of goods in the upper and middle layers of box trucks.

[0004] Therefore, in response to the problems existing in current loading machines and the current needs of factory material loading, the inventors designed an automatic loading machine with a simple structure and principle, high safety and automation, and low manufacturing cost. Utility Model Content

[0005] The purpose of this invention is to provide an automatic loading machine to solve the problem of automatic loading in the prior art.

[0006] This utility model provides the following technical solution: an automatic loading machine, including a control system and a robot platform. A material robot is fixedly installed on the top of the robot platform. A pair of pneumatic suction cups for gripping materials are installed at the end of the robotic arm of the material robot. A movable support is provided on the front side of the robot platform. A telescopic conveyor is installed on the movable support. Material platforms for stacking materials are provided on the robot platform located on both sides of the material robot. The power drive mechanisms of the material robot, pneumatic suction cups, movable support, and telescopic conveyor are respectively connected to the control system via signals.

[0007] As a preferred embodiment of the above technical solution, a set of anti-collision switches is installed at the front end of the telescopic conveyor, and the anti-collision switches are connected to the control system signal.

[0008] As a preferred embodiment of the above technical solution, the front end of the telescopic conveyor is equipped with a displacement sensor for detecting the distance between the front end of the conveyor and the material that has been fed in.

[0009] As a preferred embodiment of the above technical solution, the front end of the movable support is provided with left and right displacement sensors. The left and right displacement sensors are located on both sides of the telescopic conveyor and are equidistant from the telescopic conveyor. The left and right displacement sensors are connected to the control system.

[0010] As a preferred embodiment of the above technical solution, a first fence is provided on the outside of the robot platform to protect the material robot.

[0011] As a preferred embodiment of the above technical solution, a second fence is provided on the outside of the robot platform and the movable support.

[0012] As a preferred embodiment of the above technical solution, a safety light curtain is installed on the side of the robot platform away from the movable support.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention solves the problem of manual operation by using automatic clamping and feeding, realizes automated operation, reduces labor costs, and avoids the risk of personnel being crushed by forklifts or goods on forklifts when forklifts deliver goods into containers.

[0014] This utility model's material handling robot arm is equipped with a pair of pneumatic suction cups at its end, enabling it to simultaneously grasp two bags of materials. These bags are then transported by a telescopic conveyor to a vehicle for single-pass stacking. By using the suction cups to grip the packaging bags, damage to the materials is avoided, ensuring the quality of the goods is not affected, while simultaneously improving loading efficiency.

[0015] The robot platform of this utility model has material platforms set on both sides of the material robot. During the interval between the alternating transfer of the two material platforms, the forklift continues to replenish the materials with pallets without stopping the machine, which greatly improves the efficiency of material transfer and loading.

[0016] The anti-collision switch and displacement sensor installed at the front end of the telescopic conveyor of this utility model can detect the distance between the conveyor and the carriage and material bag in real time and transmit it to the control system so as to adjust the position of the telescopic conveyor in a timely manner.

[0017] The movable support of this utility model has left and right displacement sensors at the front end to detect the distance to both sides of the vehicle and transmit the detection data to the control system. This allows for timely adjustment of the left and right movement distance of the movable support, facilitating the loading of the telescopic conveyor into the vehicle in sequence.

[0018] The robot platform of this utility model has a safety light curtain installed on the side away from the movable support. When a person accidentally enters the light curtain or a forklift places a pallet, the safety light curtain will sense the light curtain, and the system will then alarm and the machine will stop performing the loading task.

[0019] This utility model structure can meet the loading requirements of box trucks, and can also automate the loading of the upper and middle layers of the box truck in an orderly manner, reducing manual stacking. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1 - Figure 3 As shown, this utility model provides a technical solution: an automatic loading machine, including a control system and a robot platform 1. A material robot 2 is fixedly installed on the top of the robot platform 1. A pair of pneumatic suction cups 3 for gripping materials are installed at the end of the mechanical arm of the material robot 2. A movable support 5 is provided on the front side of the robot platform 1. A telescopic conveyor 6 is installed on the movable support 5. Material platforms 4 for stacking materials are provided on the robot platform 1 located on both sides of the material robot 2. The power drive mechanisms of the material robot 2, the pneumatic suction cups 3, the movable support 5 and the telescopic conveyor 6 are respectively connected to the control system signal. The control system and the telescopic conveyor 6 used in this embodiment are commercially available equipment and are not the core technologies to be protected in this application.

[0023] By using automatic clamping and feeding, manual operation is eliminated, automated operation is achieved, labor costs are reduced, and the problem of manual operation during the high temperatures of summer is solved, avoiding heatstroke among workers. At the same time, the risk of personnel being crushed by forklifts or goods on forklifts when forklifts are delivering goods into containers is also avoided.

[0024] For an implementation method described in this embodiment, please refer to [link / reference]. Figure 1 - Figure 3 As shown, a set of anti-collision switches is installed at the front end of the telescopic conveyor 6. The anti-collision switches are connected to the control system signal to control and adjust the position of the telescopic conveyor 6 to avoid collision with the carriage.

[0025] The material platform 4 is fixed to the ground with anchor bolts. The material robot 2 is fixed to the 1800mm high material platform 4 with screws. The telescopic conveyor 6 is fixedly installed on the movable support 5. The conveyor belt on the telescopic conveyor 6 transports the goods to the designated position in the carriage. The safety net is set around the robot platform 1 and the telescopic conveyor 6 platform.

[0026] Furthermore, a displacement sensor is installed at the front end of the telescopic conveyor 6 to detect the distance between the front end of the conveyor and the material that has been placed, so that the control system can control the telescopic conveyor 6 to move back one material bag, which is convenient for subsequent sequential placement.

[0027] Furthermore, the front end of the movable support 5 is equipped with left and right displacement sensors. The left and right displacement sensors are located on both sides of the telescopic conveyor 6 and are equidistant from the telescopic conveyor 6. The left and right displacement sensors are connected to the control system signal to measure the distance to the left and right sides of the vehicle in a timely manner.

[0028] Furthermore, a first fence 8 is provided on the outside of the robot platform 1 to protect the material robot 2.

[0029] Furthermore, a second fence 9 is provided on the outside of the robot platform 1 and the movable support 5.

[0030] Furthermore, a safety light barrier is installed on the side of the robot platform 1 away from the movable support 5 to detect forklifts and people accidentally entering the material being transferred. When the safety light barrier senses an abnormality, the system alarms and the machine stops performing the loading task.

[0031] Furthermore, a power distribution cabinet 7 is fixedly installed on one side of a set of material platforms 4, and the other side of the power distribution cabinet 7 is a wall 10, with a partition 11 vertically installed at the end of the wall 10 away from the material platform 4.

[0032] Working Principle: After the loading van stops at the designated location, the forklift operator uses a forklift to move the goods (with pallets) to be loaded onto material platform 4. The loading operator sets the loading quantity on the control panel. After the forklift places the pallet and exits the enclosure area, the operator sets the number of pallet layers, number of dismantling steps, and suction cup options on the control panel according to the material situation on the pallet (no need to set when the pallet is full). The operator confirms the stack number (left or right stack) using the remote control button for the pallet placement. After the data setting steps are completed, if the system is stopped, the start button needs to be pressed to start the system. If the system is running, this step is not required (the system defaults to prioritizing dismantling the left stack; after dismantling one stack, the system will automatically switch to another stack). Then, the material robot 2 combines with a pair of pneumatic suction cups 3 to remove the goods from the pallet. Two bags are grabbed at a time and placed on the left and right sides of the telescopic conveyor 6 platform. At this time, the telescopic conveyor 6 extends to the front of the container and transports the goods into the container. During the transport of the goods on the conveyor belt of the telescopic conveyor 6, the material bags fall from the left and right sides of the conveyor belt to the left half of the container in turn. Then the conveyor belt moves back one bag's distance, and one bag falls on each side again. If only one bag is left, only one bag is grabbed and the conveyor continues to transport. The conveyor belt moves back in turn until the first two rows of goods on the left half of the container are loaded. Then the movable support 5 drives the telescopic conveyor 6 to move to the right half of the container and load the first layer on the right half of the container in turn. After the first layer is loaded, the conveyor belt returns to the left half of the container to load the second layer, and then moves to the right to load the second layer on the right half, and so on, until the container is full of goods as planned.

[0033] Before the development of this utility model, loading a truckload of goods required 2-3 workers, taking 50 minutes per truck. With 10 truckloads per day, it would take 8 hours to complete the work. During the hot summer months, only 4 truckloads could be completed between 8:00 AM and 11:20 AM. Work was suspended at midday to avoid the high temperatures, and the remaining 4 truckloads were completed between 3:00 PM and 6:20 PM, totaling approximately 10 hours. Even outside of hot weather, each package of goods weighs 25 kg, and continuous work would gradually reduce worker stamina, decrease efficiency, and increase safety risks. With the automatic loading machine of this utility model, each truckload takes only 60 minutes to load, and the total work time is 8 hours, significantly improving loading efficiency and reducing waiting time for both manpower and logistics company vehicles.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
