It should be noted that, first, the motor driving the rotating disc 121 to rotate may be a stepping motor, and the purpose of the motor is to control the rotation of the rotating disc 121, so that the rotating disc 121 can intermittently rotate relative to the frame 110, and an angle of each rotation is an angle difference between two adjacent stations 123, in such a way, each rotation of the rotating disc 121 can enable the station 123 to rotate to a position corresponding to a next feeding unit along a rotation direction of the rotating disc 121; so that a single rotation of the rotary disc 121 can enable the containers at each station 123 to be sequentially rotated to the corresponding positions of the plurality of feeding units of the feeding assembly 130 along the rotation direction of the rotary disc 121.
Secondly, in this embodiment, the feeding unit includes a first feeding unit 131, a second feeding unit 132, and a third feeding unit 133 for illustration, and in this embodiment of the present invention, the feeding assembly 130 may further include a fourth and a fifth feeding units, and so on;
the operating principle of the packaging machine 100 is:
referring to fig. 1-4, the packaging machine 100 includes a frame 110, a rotating assembly 120, a loading assembly 130, a metering assembly, and a gripper robot 150;
wherein the position of each station 123 can be switched by the rotation of the rotary disc 121 relative to the frame 110; moreover, each station 123 is provided with a clamp 122 for clamping a container, and then the position of the container on the rotating disc 121 can be switched through the rotation of the rotating disc 121, so that the material adding efficiency of the container clamped on the rotating disc 121 can be improved in such a way, and the containers in each station 123 can be loaded at the same time. The feeding unit is used for adding materials to each rotating container, and the feeding assembly 130 comprises a plurality of feeding units, so that the materials can be fed step by step through the plurality of feeding units, and the feeding precision of the materials can be improved. And the gripper robot 150 is used to transfer containers to and from the rotating disk 121.
Specifically, in the process that the rotary disc 121 rotates relative to the frame 110, the containers on the rotary disc 121 rotate synchronously, so that each station 123 on the rotary disc 121 sequentially passes through the first feeding unit 131, the second feeding unit 132 and the third feeding unit 133, and further, in such a manner, the containers on each station 123 pass through the first feeding unit 131, the second feeding unit 132 and the third feeding unit 133, and can be loaded according to the weight of the container in each station 123 measured by the metering assembly; in this way, the containers clamped in the stations 123 on the rotating disc 121 can be circulated relative to the feeding assembly 130 through the rotation of the rotating disc 121, and the feeding accuracy of the materials can be improved through this way;
in the case of the charging step, the object is to add a target weight of the material to the container; since the addition of each material is not accurate, the material of the target weight to be added into the container can be added step by step in the adding process, that is, the sum of the first preset weight and the second preset weight is less than or equal to the target weight, and the third preset weight is a material supplementing step; for example, as the rotating disc 121 rotates, after the container passes through the first feeding unit 131 and the second feeding unit 132 in sequence, the first preset weight and the second preset weight of the material are added to the container; meanwhile, the weight of the container is measured through the metering assembly, so that the difference between the actual weight of the material in the container and the target weight can be determined, and the different material can be supplemented into the container through the third feeding unit 133; because the single-time feeding weight of the third feeding unit 133 is the third preset weight, the number of times that the third feeding unit 133 adds the material to the container can be determined according to the weight difference of the material, and then the material can be fed for many times by the third feeding unit 133, thereby completing the material adding work;
the target weight may also be a multiple of the sum of one or more of the first preset weight, the second preset weight, and the third preset weight, that is, since the first preset weight, the second preset weight, and the third preset weight are fixed values, one or more of the first feeding unit 131, the second feeding unit 132, and the third feeding unit 133 may feed the container one or more times along with the rotation of the rotating disc 121 until the target weight is reached; in this feeding manner, the container can be circulated through the first feeding unit 131, the second feeding unit 132 and the third feeding unit 133 by the rotation of the rotary disc 121, so that the addition of the material can be completed in this manner.
When the working principle of the feeding assembly 130 is as follows: so that the sum of the first preset weight and the second preset weight is less than or equal to the target weight, and the third preset weight is a material supplementing step; for example, as the rotating disc 121 rotates, after the container passes through the first feeding unit 131 and the second feeding unit 132 in sequence, the first preset weight and the second preset weight of the material are added to the container; meanwhile, the weight of the container is measured through the metering assembly, so that the difference between the actual weight of the material in the container and the target weight can be determined, and the different material can be supplemented into the container through the third feeding unit 133; the packaging machine 100 operates as follows:
firstly, determining preset weights of all feeding units in the feeding assembly 130 according to a target weight for adding materials into the container, namely, determining a first preset weight, a second preset weight and a third preset weight according to the target weight, and sequentially reducing the first preset weight, the second preset weight and the third preset weight; and wherein the sum of the first predetermined weight and the second predetermined weight is less than or equal to the target weight;
subsequently, the container with the added material is placed in the station 123 of the rotating disc 121 closest to the gripper robot 150 by the gripper robot 150, and the station 123 close to the gripper robot 150 is replaced along with the rotation of the rotating disc 121, so that the gripper robot 150 can sequentially add the container to the gripper 122 in each station 123 on the rotating disc 121 according to the intermittent rotation manner of the rotating disc 121;
when one of the stations 123 with containers rotates to a position corresponding to the first feeding unit 131 along with the rotation of the rotating disc 121, the rotating disc 121 stops rotating, and the first feeding unit 131 starts feeding; after the first feeding unit 131 finishes feeding, the weight of the materials in the container is measured;
then, rotating to a position corresponding to the second feeding unit 132, feeding, and after the second feeding unit 132 finishes feeding, measuring the weight of the material in the container;
determining whether the third feeding unit 133 needs to add the material into the container according to the difference between the actual weight of the material in the container and the target weight, and determining the number of times the third feeding unit 133 needs to add the material into the container;
until the weight in the container reaches the target weight, or the difference between the actual material weight in the container and the target weight meets the requirement.
When the working principle of the feeding assembly 130 is as follows: the target weight is a multiple of the sum of one or more of the first preset weight, the second preset weight and the third preset weight, that is, because the first preset weight, the second preset weight and the third preset weight are constant values, one or more of the first feeding unit 131, the second feeding unit 132 and the third feeding unit 133 can feed the container one or more times along with the rotation of the rotating disc 121 until the target weight is reached; in such a feeding manner, the container can be circulated through the first feeding unit 131, the second feeding unit 132 and the third feeding unit 133 by the rotation of the rotating disc 121, so that the addition of the material can be completed in such a manner; the operation of the packaging machine 100 is as follows:
firstly, determining preset weights of all feeding units in the feeding assembly 130 according to a target weight for material addition of a container, that is, determining a first preset weight, a second preset weight and a third preset weight according to the target weight, and feeding times of the first feeding unit 131, the second feeding unit 132 and the third feeding unit 133; it should be noted that the first preset weight, the second preset weight and the third preset weight are sequentially reduced, and the target weight is a multiple of the sum of one or more of the first preset weight, the second preset weight and the third preset weight;
taking the target weight as twice of the sum of the first preset weight, the second preset weight and the third preset weight as an example; after the material clamping mechanical arm 150 starts to add containers to the rotating disc 121, along with the rotation of the rotating disc 121, when one of the stations 123 filled with the containers rotates to a position corresponding to the first material loading unit 131, the rotating disc 121 stops rotating, and the first material loading unit 131 starts to load materials; after the first feeding unit 131 finishes feeding, the weight of the materials in the container is measured;
then, rotating to a position corresponding to the second feeding unit 132, feeding, and after the second feeding unit 132 finishes feeding, measuring the weight of the material in the container; rotating to a position corresponding to the third feeding unit 133, feeding, and after the third feeding unit 133 finishes feeding, measuring the weight of the material in the container;
and then circulating according to the steps until the weight in the container reaches the target weight or the difference between the actual material weight in the container and the target weight meets the requirement.
Further, referring to fig. 1 to 6, in the present embodiment, the material clamping robot 150 is used to transfer the containers to the rotating disc 121 or to remove the containers on the rotating disc 121; in order to improve the working efficiency of the packaging machine 100, the material clamping mechanical arm 150 is used for transferring the containers to the rotating disc 121, the rotating disc 121 is provided with a plurality of blanking channels 124, the plurality of blanking channels 124 correspond to the plurality of stations 123 one by one, and the clamps 122 on the same station 123 are all located right above the blanking channels 124. That is, the clamping robot 150 may be used to transfer the containers to the rotating disk 121, and the blanking may be performed through the blanking passage 124. Thus, the feeding and discharging of the packaging machine 100 are independent from each other in such a manner, so as to improve the working efficiency.
The packaging machine 100 further includes a blanking conveyor assembly 160 located below the rotating disc 121, the blanking conveyor assembly 160 being configured to receive all of the containers output by the blanking lanes 124.
Therefore, by the arrangement mode, after the containers in each station 123 are completely loaded, the containers can fall into the blanking conveying assembly 160 from the blanking channel 124 in the station 123, and the blanking efficiency can be improved.
Specifically, when the blanking conveying assembly 160 is arranged, the blanking conveying assembly 160 includes a first conveying belt 161 and a second conveying belt 162, the first conveying belt 161 is arc-shaped and is arranged around the rotation axis of the rotating disc 121 and is located below all the blanking channels 124, and the first conveying belt 161 is used for receiving containers output by all the blanking channels 124; the feed end of the second conveyor belt 162 communicates with the discharge end of the first conveyor belt 161, and the second conveyor belt 162 serves to output the containers to the outside.
Further, referring to fig. 1 to 6, in the present embodiment, since a certain height difference exists between the first conveyor belt 161 of the blanking conveyor assembly 160 and the rotation, in order to prevent the containers from being impacted too much and prevent the rotating disc 121 from interfering the containers on the first conveyor belt 161 to move along with the first conveyor belt 161, the packaging machine 100 further includes a plurality of buffer units 170, the plurality of buffer units 170 are connected to the plurality of stations 123 in a one-to-one correspondence, and each buffer unit 170 is located right below the blanking channel 124 of the corresponding station 123 and located between the blanking conveyor assembly 160 and the rotating disc 121;
