Description

Technical Field

[0001] The present invention relates to the technical field of automatic bagging, and particularly relates to an automatic device and its working method for automatically picking up bags, expanding bags, and discharging materials for material products such as nuts. Background Art

[0002] In the mass production environment of modern industrial assembly lines, the packaging process of nut products includes multiple steps such as bag picking, bag opening, discharging, and putting back. The whole process is extremely cumbersome. Since these steps are all completed manually, not only does the labor cost remain high, but also the working efficiency of bagging nut products such as melon seeds is severely restricted. When workers pick up bags, it may be difficult to quickly obtain them due to the random placement of paper bags, and even the bags may stick to each other due to factors such as static electricity, further increasing the operation difficulty and time cost. In the bag opening link, it is difficult for workers to hold open plastic bags with one hand, especially for larger-sized bags, which is even more difficult to control with one hand, affecting the smoothness of production. During the discharging process, workers need to frequently shovel melon seeds with a shovel and put them into the bag. The arm needs to be continuously lifted up and down, and at the same time, the increase and decrease of melon seeds need to be accurately controlled. The operation is complex and prone to errors.

[0003] Chinese Patent CN108792047A discloses "an automatic melon seed bagging machine", which includes a material transfer mechanism, a plastic bag opening mechanism, and a plastic bag transportation mechanism. The material transfer mechanism pushes melon seeds into the plastic bag opened by the plastic bag opening mechanism, and the plastic bag transportation mechanism transports the plastic bag to the plastic bag opening mechanism. This technical solution can achieve automatic bagging of melon seeds through the coordinated operation of the mechanisms, but this disclosed technology is not an independent device and needs to be installed on an existing device to complete the corresponding work, causing inconvenience to on-site installation and operation; it cannot perform paper bag packaging on melon seeds; the process of expanding and storing bags is relatively complex; it cannot achieve the transportation of melon seeds after bagging, which is not convenient for the next step of bag sealing operation. It needs to be used in conjunction with other devices when in use, which is cumbersome to use, not easy to operate, and not conducive to popularization in the factory production process of melon seeds; the existing technology also has the problem that it cannot monitor equipment abnormalities and perform repairs in a timely manner. Summary of the Invention

[0004] The purpose of the present invention is to provide a material automatic bagging machine and its working method to solve the problems raised in the above background art.

[0005] The first aspect embodiment of the present application proposes a working method for a material automatic bagging machine, and this working method includes the following steps:

[0006] Step 1, power on the machine;

[0007] Step 2, determine whether the bag storage mechanism, bag expanding mechanism, bagging mechanism, transportation mechanism, and pneumatic device are reset. If all are reset, then enter Step 3;

[0008] Step 3: The motor gear of the bag-supporting mechanism rotates to drive the grasping mechanism to move upward until the suction cup adsorbs the paper bag in the paper bag storage box. After the grasping mechanism reaches the preset specified position, the solenoid valve of the suction cup is opened, and the suction cup uses negative pressure to suck the paper bag. Then, the motor gear rotates in reverse to drive the grasping mechanism to move downward.

[0009] Step 4: After the grasping mechanism moves downward with the paper bag to a certain position, the motor gear drives it to rotate counterclockwise by 90° to adjust the direction of the paper bag. The grasping mechanism moves towards the adsorption mechanism driven by the motor gear. After reaching the adsorption mechanism, the solenoid valve of the adsorption mechanism is opened, and its suction cup sucks on the other side of the paper bag to achieve the operation of adsorbing and pulling open the paper bag.

[0010] Step 5: After the suction cup of the adsorption mechanism holds the packaging bag, the grasping mechanism moves backward and cooperates with the adsorption mechanism to pull open the paper bag. When the paper bag is pulled open to the preset position, the bag-supporting mechanism moves downward driven by the motor gear to fully open the paper bag. After the bag-supporting action is completed, the bag-supporting mechanism moves upward to return to the initial position.

[0011] Step 6: The bag-pushing mechanism pushes the opened paper bag onto the running transport device, and the paper bag starts to be transported forward. When the paper bag moves below the feeding mechanism, the sensor under the feeding mechanism detects that the opened packaging bag reaches the preset distance to prepare for material filling.

[0012] Step 7: The feeding mechanism opens the solenoid valve switch of the feeding port, and the follower baffle opens, and the material in the storage bin falls into the paper bag below. After the preset delay time of the time relay, the feeding port closes and stops material filling.

[0013] Step 8: The controller controls the motor of the transport device to operate at a preset increased power, and the paper bag filled with material continues to be transported forward driven by the belt conveyor and leaves the bagging area.

[0083] This embodiment also includes a working method of a material automatic bagging machine, which is applied to a material automatic bagging machine of any of the above technical solutions, and the above material automatic bagging machine is realized through the working method of the material automatic bagging machine.

[0084] A working method of a material automatic bagging machine according to this embodiment, the working method includes the following steps:

[0085] Step 1, power on;

[0086] Step 2, determine whether the bag storage mechanism, the bag supporting mechanism, the bagging mechanism, the transportation mechanism, and the pneumatic device are reset. If all are reset, enter Step 3;

[0087] Step 3, the motor gear of the bag supporting mechanism rotates, driving the grasping mechanism to move upward until the suction cup adsorbs the paper bag in the paper bag storage box. After the grasping mechanism reaches the preset specified position, the solenoid valve of the suction cup is opened, and the suction cup uses negative pressure to suck the paper bag; then, the motor gear rotates in reverse, driving the grasping mechanism to move downward;

[0088] Step 4, after the grasping mechanism moves downward with the paper bag to a certain position, the motor gear drives it to rotate counterclockwise by 90° to adjust the direction of the paper bag; the grasping mechanism moves towards the adsorption mechanism driven by the motor gear. After reaching the adsorption mechanism, the solenoid valve of the adsorption mechanism is opened, and its suction cup sucks on the other side of the paper bag to realize the adsorption and pulling operation of the paper bag;

[0089] Step 5, after the suction cup of the adsorption mechanism sucks the packaging bag, the grasping mechanism moves backward and cooperates with the adsorption mechanism to pull the paper bag; when the paper bag is pulled to the preset position, the bag supporting mechanism moves downward driven by the motor gear to fully open the paper bag; after the bag supporting action is completed, the bag supporting mechanism moves upward and returns to the initial position;

[0090] Step 6: The bag pushing mechanism pushes the opened paper bag onto the running transport device, and the paper bag starts to be transported forward. When the paper bag moves below the feeding mechanism, the sensor under the feeding mechanism detects that the opened packaging bag reaches the preset distance, preparing for material filling.

[0091] Step 7: The feeding mechanism turns on the solenoid valve switch of the feeding port, and the follower baffle opens. The material in the storage bin falls into the paper bag below. After the preset delay time of the time relay, the feeding port closes and the material filling stops.

[0092] Step 8: The controller controls the motor of the transport device to run at a preset increased power. The paper bag filled with material continues to be transported forward under the drive of the belt conveyor and leaves the bagging area.

[0093] Specifically, the specific implementation process is as follows:

[0094] Step 1: Preparation before bagging: The operator first neatly places the stacked paper bags in the paper bag storage bins on both sides to provide packaging materials for bagging; pours materials such as nuts into the storage bin to complete material reserve. After completing the above preparations, the operator presses the start button on the control cabinet to start the entire bagging process.

[0095] Step 2: Equipment startup and initial state confirmation: After the start button is pressed, the motor of the belt conveyor enters the running state, and the transport device starts to run, preparing for subsequent transportation of the bagged materials; the air pump starts and enters the standby state, ready to supply air to the relevant pneumatic mechanisms at any time. Subsequently, the controller detects the states of the bag storage mechanism, bag stretching mechanism, bagging mechanism, transport mechanism, and pneumatic device to determine whether each mechanism is reset. If there is an unreset mechanism, the control device performs a reset operation to return it to the initial state; if all mechanisms are reset, proceed to the next step.

[0096] Step 3: Packaging bag grasping operation: After confirming that the mechanism state is normal or after completion of reset, the motor gear of the bag stretching mechanism rotates, driving the grasping mechanism to move upward until the suction cup adsorbs the paper bag in the paper bag storage bin. After the grasping mechanism reaches the preset specified position, the solenoid valve of the suction cup is opened, and the suction cup uses negative pressure to suck the paper bag. Then, the motor gear rotates in reverse, driving the grasping mechanism to move downward.

[0097] Step 4: Packaging bag adsorption: After the grasping mechanism moves downward with the paper bag to a certain position, the motor gear drives it to rotate counterclockwise by 90° to adjust the direction of the paper bag. Then, the grasping mechanism moves towards the adsorption mechanism under the drive of the motor gear. After reaching the adsorption mechanism, the solenoid valve of the adsorption mechanism is opened, and its suction cup adsorbs on the other side of the paper bag to achieve the adsorption and stretching operation of the paper bag.

[0098] Step 5, bag stretching operation: After the suction cup of the adsorption mechanism sucks the packaging bag, the grasping mechanism moves backward and cooperates with the adsorption mechanism to pull open the paper bag. When the paper bag is pulled open to an appropriate position, the bag stretching mechanism moves downward driven by the motor gear to fully stretch the paper bag. After the bag stretching action is completed, the bag stretching mechanism moves upward and returns to the initial position to prepare for the next action.

[0099] Step 6, pushing the bag and preparing for material filling: After the bag stretching is completed, the bag pushing mechanism pushes the stretched paper bag onto the running transport device, and the paper bag starts to be transported forward. When the paper bag moves below the feeding mechanism, the sensor under the feeding mechanism detects the approaching of the stretched packaging bag to prepare for material filling.

[0100] Step 7, material filling operation: After the sensor of the feeding mechanism detects the approaching of the stretched packaging bag, the solenoid valve switch of the feeding port of the feeding mechanism is opened, the follow-up baffle is opened, and the material in the storage bin falls into the feeding mechanism by gravity and then into the paper bag below. After the preset delay time of the time relay, the feeding port is closed and the material filling stops.

[0101] Step 8, completing bagging and conveying: After the feeding port is closed, the controller issues an instruction to control the motor of the transport device to operate at increased power. The paper bag filled with material continues to be transported forward driven by the belt conveyor, leaves the bagging area, and completes a complete automatic material bagging process.

[0102] As a technical optimization solution of the present invention, a monitoring unit is further provided. The monitoring unit can monitor the state parameters of the grasping mechanism, the adsorption mechanism, and the bag stretching module. The monitoring unit includes a grasping mechanism monitoring unit and a bag stretching module monitoring unit. The grasping mechanism monitoring unit and the bag stretching module monitoring unit respectively monitor the state parameters of the grasping mechanism and the bag stretching module; the controller is communicatively connected to each detection unit to obtain the state parameters monitored by each monitoring unit;

[0103] The controller analyzes the current state parameter data, where the current parameter data is the state parameters of the grasping mechanism and the bag stretching module; if it is determined according to the pre-set abnormal determination rules that there is an abnormality in the state parameters, the location and type of the abnormality of the material automatic bagging machine are determined; among them, the pre-set abnormal determination rules include that the rotation speed of the grasping mechanism is lower than the first preset rotation speed, the moving speed of the bag stretching module is higher than the second preset threshold, and whether the rotation motor of the grasping mechanism and the transmission motor of the bag stretching module are stopped; the controller sends corresponding control instructions to the indicator light and voice broadcast to achieve monitoring and alarm.

[0104] Further, before receiving the status parameter, it also includes obtaining the historical abnormal status data of the material automatic bagging machine through the Internet; analyzing the historical abnormal status data through an empirical model to obtain the deployment positions of the monitoring units of the automatic bagging machines of the same model, so as to deploy monitoring units at other positions of the same model.

[0105] For example, if monitoring units are provided in the bag pushing mechanism and the bagging mechanism of the automatic bagging machines of the same model, it indicates that the bag pushing mechanism and the bagging mechanism of the automatic bagging machines of the same model are mechanisms prone to failure and need to be monitored key points. Then, in order to improve the safe operation, monitoring units are also provided in the bag pushing mechanism and the bagging mechanism of this automatic bagging machine for key monitoring.

[0106] Further, before receiving the status parameter, it also includes adding a mute control instruction to stop the voice broadcast when the staff is repairing.
