Description

Technical Field

[0001] The present invention belongs to the technical field of material conveying equipment, and in particular relates to a conveying mechanism for intelligent loading of bagged materials by robots. Background Art

[0002] In the process of loading bagged cement, automatic transportation is often achieved through conveyor belts, but in the final unloading and loading steps, or the transportation process from one conveyor belt to another, manual transportation is often required. With the continuous development of industrial automation, it has become a reality for robots to imitate manual labor to complete part of the work. In the existing technology, conveying mechanisms are used in conjunction with robots to achieve automatic loading of bagged cement, which can replace people's heavy labor and realize mechanization and automation of production.

[0003] The existing unloading robot for bagged cement usually uses a conveying mechanism to transport the bagged cement on the vehicle to the bottom during use, and drives the robot to drive the mechanical arm to control the clamping of the bagged cement, and installs a set program to complete intelligent stacking. However, the cement powder in the bagged cement is not completely full, so that the cement powder is unevenly distributed in the bag. During the unloading process, the bagged cement has an irregular volume due to the uneven distribution of cement powder inside. When unloading and stacking after clamping, the actual stacking of the bagged cement with uneven volume is unstable. As the stacking height increases, the stacked bagged cement is prone to tipping and overturning. Moreover, the volume of cement powder inside the cement bag is limited, and a large amount of cement powder is attached to the surface of the packaging bag. Under the effects of impact and vibration, the cement powder on the surface of the bagged cement is easy to disperse and rise. In fact, when the loading robot clamps and stacks, when the falling bagged cement collides with the bagged cement at the bottom, a relatively serious dust situation will occur, which reduces the environmental quality of the unloading site, and the surface of the unloading robot collects dust seriously, which will cause the robot to malfunction in the long run. Summary of the invention

[0004] The purpose of the present invention is to provide a conveying mechanism for intelligent loading of bagged materials by robots, so as to solve the problem that bagged materials such as cement are easily stacked unstably during loading by robots, resulting in dumping and dust.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A conveying mechanism for intelligent loading of bagged materials by a robot, the conveying mechanism comprising a conveyor belt and a material leveling mechanism and a controller thereof arranged at one end of the conveyor belt, the material leveling mechanism comprising an outer frame and an inner frame slidably sleeved in the outer frame, a bearing platform with a lifting function is arranged in the inner frame, the bagged materials are transferred to the inner frame through the conveyor belt, and after being leveled, are transferred to the upper end of the inner frame through the bearing platform, and the bagged materials are transferred from the conveying mechanism to the vehicle to be loaded through a robotic arm;

[0007] A distance sensor for monitoring the sliding distance of the inner frame and a vibration component for driving the inner frame to vibrate in the vertical direction are provided at the sliding joint between the outer frame and the inner frame. An air port and a dust removal component connected to the air port are provided on the side wall of the inner frame.

[0008] An air curtain tube is arranged on the top of the inner frame, and a nozzle is opened on the air curtain tube, and the nozzle is connected with an air pipe through an external air pump;

[0009] When the bagged material falls into the inner frame until the inner frame moves down to a preset distance value, the distance sensor transmits a signal to the controller, and the controller controls the vibration component, the dust removal component and the air pump to work. The vibration component drives the inner frame to move upward along the outer frame, thereby vibrating and leveling the bagged material in the inner frame. When the dust removal component is working, it collects the dust generated in the inner frame. When the air pump is working, it transports air into the air curtain tube, and the air is sprayed out from the nozzle on the side of the air curtain tube to form an air curtain. The air curtain can block the dust in the inner frame from entering the outside air, thereby avoiding pollution of the external air of the conveying mechanism.

[0010] As a further optimization solution of the present invention, a first channel and a second channel are respectively provided on the outer frame and the inner frame corresponding to the ends of the conveyor belt, and the caliber of the first channel is smaller than that of the second channel.

[0011] As a further optimization solution of the present invention, a buffer airbag is provided in the outer frame corresponding to the lower end surface of the inner frame, and the buffer airbag is connected to the air pump through air pipe 2.

[0012] As a further optimization scheme of the present invention, the side of the inner frame is slidably arranged on the side of the outer frame through a support plate, and the side of the outer frame facing the inner frame is also provided with a mounting frame for installing the vibration component, and a damping spring is provided between the mounting frame and the support plate.

[0013] As a further optimization solution of the present invention, the vibration assembly includes a rotating motor arranged on the mounting frame and a cam arranged at the output end of the rotating motor, and the support plate is arranged on the rotation path of the cam.

[0014] As a further optimization scheme of the present invention, the dust removal assembly includes a cover plate installed on the side of the inner frame, a collection bin connected to the interior of the cover plate, an air port is provided in the inner frame and the covering space of the cover plate, and an exhaust fan is provided on the connecting pipe between the cover plate and the collection bin.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1) In the present invention, the controller is used to realize the operations of conveying, vibrating and leveling the bagged materials, recovering dust, etc., so as to realize the automatic conveying of the bagged materials, reduce the manpower cost of the enterprise, and make it easier for the robot arm to transfer and load the materials;

[0017] 2) The present invention removes dust from bagged materials by vibration, and cooperates with an air pump to form an air curtain at the upper end of the open inner frame, which can prevent dust in the inner frame from entering the outside air and avoid polluting the outside air of the conveying mechanism. It is obviously more suitable for the transfer and conveying of bagged powders;

[0018] 3) In the present invention, the air curtain is formed by the air pump, and the air pump can be linked to inflate the buffer airbag between the inner frame and the outer frame. The inflated buffer airbag can produce a buffering effect on the connection between the inner frame and the outer frame, preventing the inner frame from suddenly falling and causing damage to the outer frame, thereby improving the safety performance of the entire conveying mechanism.

[0025] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Example 1

[0027] like Figure 1-5 As shown, a conveying mechanism for intelligent loading of bagged materials by a robot is shown. The conveying mechanism includes a conveyor belt 3 and a material leveling mechanism and a controller thereof arranged at one end of the conveyor belt 3. The material leveling mechanism includes an outer frame 31 and an inner frame 32 slidably sleeved in the outer frame 31. A carrying platform 18 with a lifting function is arranged in the inner frame 32. The bagged materials are transferred to the inner frame 32 through the conveyor belt 3, and are transferred to the upper end of the inner frame 32 through the carrying platform 18 after being acted upon by the material leveling mechanism. The bagged materials are transferred from the conveying mechanism to the vehicle 2 to be loaded through the robot arm 1.

[0028] It should be noted that the present application does not limit the transfer location of the bagged materials, and the transfer process that is mainly protected is the leveling process of the bagged materials.

[0029] The present application aims at the problem that the bagged materials are easily unevenly distributed in the bag during the prior art when the bagged materials are transferred and loaded or transferred and stored. When the bagged cement with uneven volume is unstacked after clamping, the actual stacking is unstable. As the stacking height increases, the stacked bagged materials are prone to tipping and overturning. Specifically:

[0030] A distance sensor 10 for monitoring the sliding distance of the inner frame 32 and a vibration component for driving the inner frame 32 to vibrate in the vertical direction are provided at the sliding joint between the outer frame 31 and the inner frame 32. An air port 21 and a dust removal component connected to the air port 21 are provided on the side wall of the inner frame 32.

[0031] An air curtain tube 15 is provided on the top of the inner frame 32, and a nozzle 25 is provided on the air curtain tube 15. An air pump 13 is provided on the outer frame 31, and the air pump 13 is connected to the air curtain tube 15 through an air pipe 14.

[0032] The output end of the distance sensor 10 is connected to the input end of the controller, and the output end of the controller is respectively connected to the control ends of the conveying component, the air pump 13, the vibration component, and the dust removal component.

[0033] When the conveying mechanism is in use, the conveyor belt 3 transfers the bagged materials into the inner frame 32 and drops them onto the carrying platform 18. When multiple bagged materials fall into the inner frame 32 until the inner frame 32 moves down to a preset distance value, the distance sensor transmits a signal to the controller, and the controller controls the vibration component, the dust removal component and the air pump to work. The vibration component drives the inner frame 32 to move up along the outer frame 31, thereby vibrating and leveling the bagged materials in the inner frame 32, so that the materials in the belt tend to be regular, so as to facilitate the stability of the stacking in the later stage. In this process, the bagged materials are prone to generate dust due to vibration. At this time, the dust collection component can collect the dust generated in the inner frame 32; in order to overcome the open design of the upper end of the inner frame 32, the present application is provided with an air pump 13. When the air pump 13 is working, the air is transported to the air curtain tube 15, and finally sprayed out from the nozzle 25 on the side of the air curtain tube 15 to form a wind curtain. The wind curtain can prevent the dust in the inner frame 32 from entering the outside air, thereby avoiding pollution of the external air of the conveying mechanism.

[0034] To further facilitate the transfer of bagged materials from the conveying mechanism to the inner frame 32 , a first channel 19 and a second channel 20 are respectively provided on the outer frame 31 and the inner frame 32 corresponding to the ends of the conveyor belt 3 , and the diameter of the first channel 19 is smaller than that of the second channel 20 .

[0035] In order to further protect the inner frame 32 and the outer frame 31 during the vibration and leveling process of the inner frame 32, a buffer airbag 17 is provided in the outer frame 31 corresponding to the lower end surface of the inner frame 32, and the buffer airbag 17 is connected to the air pump 13 through the air pipe 16. During the vibration and leveling process of the bagged material, the buffer airbag 17 can also be inflated in the process of the air pump 13 driving the air curtain to form. The inflated buffer airbag 17 can produce a buffering effect on the connection between the inner frame 32 and the outer frame 31 to prevent the inner frame 32 from suddenly falling and causing damage to the outer frame 31.

[0036] In the present application, a pressure sensor is provided inside the cushioning airbag 17, and a solenoid valve is provided on the air pipe 16. When the internal pressure value exceeds a preset value, the solenoid valve on the connecting pipeline cuts off the air supply.

[0037] In order to further improve the stability of the inner frame 32 when the bagged material is transferred into the inner frame 32, the side of the inner frame 32 is slidably arranged on the side of the outer frame 31 through the support plate 7, and the side of the outer frame 31 facing the inner frame 32 is also provided with a mounting frame 9 for installing the vibration component, and a damping spring 8 is provided between the mounting frame 9 and the support plate 7.

[0038] The specific structure of the vibration component in the present application is: the vibration component includes a rotating motor 11 arranged on the mounting frame 9 and a cam 12 arranged at the output end of the rotating motor 11, and the support plate 7 is arranged on the rotation path of the cam 12. The cam 12 is driven to rotate by the rotating motor 11, and the rotating cam 12 hits the support plate 7 to drive the inner frame 32 to vibrate up and down.

[0039] The specific structure of the vibration component in the present application is: the dust removal component includes a cover plate 22 covered on the side of the inner frame 32, and a collection bin 24 connected to the inside of the cover plate 22. The inner frame 32 is provided with an air port 21 in the covering space of the cover plate 22, and an exhaust fan 23 is provided on the connecting pipeline between the cover plate 22 and the collection bin 24.

[0040] It should be noted that the conveying mechanism in the present application is not limited to the use for loading and transporting bagged cement, and the method of using the device to load and transport other materials should also be covered within the protection scope of the present application.

[0041] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
