Description

Technical Field

[0001] The invention relates to the technical field of fruit weighing and canning, and in particular to a traveling combined weighing device and method suitable for fragile fruits. Background Art

[0002] Citrus is one of the main fruits in my country. It has a good taste, high edible rate and rich nutrients. In addition to being eaten fresh, citrus is mainly processed into juice, canned food, cysts, etc. When preparing canned food, it is necessary to ensure that the weight of the orange segments in each can is within a reasonable weight range. The existing canning process is: first can the orange segments and weigh them manually. If there is a weight difference, they are taken out or supplemented manually, and then the cans are packaged. The entire weighing and canning process requires manpower to complete, which is more labor-intensive, labor-intensive, and has high production costs and low work efficiency. The production rhythm cannot keep up with the market supply demand; the production of canned food has very strict hygiene requirements. Manual weighing and canning will cause canned food safety problems due to foreign matter such as sweat stains; manual weighing will also cause problems such as too heavy a piece is too heavy and not enough a piece is too heavy.

[0003] Since orange peels are fragile and easy to stick to the wall of the equipment after being removed from the shell, the common weighing equipment such as multi-head combination weighers has a large drop, which will cause the orange peels to break, and the adhesion to the wall will cause inaccurate weighing and difficulty in feeding. Therefore, the automation of canning weighing for this type of fruit has not been solved. Summary of the invention

[0056] (S01) starting the first transmission device, the weighing assembly, the delivery device and the push-down assembly, and continuously feeding materials into the lower hopper;

[0057] (S02) Controlling the material discharge port of the material discharge hopper in step (S01) to be opened, and when the material falls into the weighing hopper, controlling the material discharge port of the material discharge hopper to be closed;

[0058] (S03) After weighing in step (S02), the weighing bucket transmits the weight information to the controller, and at the same time controls the discharge port of the weighing bucket to open.

The components work, and the weight of materials in different discharge hoppers is summed up through permutations and combinations to reach the built-in weight range of the controller. When the discharge hoppers in the permutations and combinations reach the corresponding conveying channels, the corresponding push-down components above the conveying channels push the corresponding discharge hoppers to discharge materials into the conveying channels. In this way, the total weight of fragile fruits in each conveying channel is the total weight required for the filling container.

[0065] The present invention has the following beneficial effects:

[0066] (1) The first transmission device can drive a plurality of discharge and unloading devices to continuously pass through the weighing component and the conveying channel. The weighing component continuously drops the weighed fragile fruits into the discharge component. The system sets the weight of the fragile fruits to be loaded into each container. Under the transmission of the first transmission device, the discharge device continuously passes through the conveying channel. The system comprehensively combines the weights of the fragile fruits in all the discharge components. When the combined discharge components arrive at the conveying channel, the push-down components at the corresponding positions push the discharge components to pour the fragile fruits in the discharge components into the conveying channel, so that the weight of the fragile fruits arriving at the conveying channel is the weight of the fragile fruits to be canned. This is repeated to automatically and accurately load the fragile fruits of a specified weight into the container. The entire working process has a high degree of automation, low labor intensity, no health hazards, and a relatively uniform weight of the fragile fruits, which is suitable for industrial production.

[0067] (2) Driven by the first transmission device, a plurality of discharge and unloading devices can continuously pass through the location of the weighing component and the delivery device. Each discharge and unloading component corresponds to a single weighing component and a push-down component in a cycle. The fragile fruits falling after being weighed by the weighing component are first stably caught, and then pushed by the corresponding push-down component to completely pour the fragile fruits into the corresponding conveying channel, which has good working stability and flexibility;

[0068] (3) Several weighing components are arranged in parallel on the bracket. According to the system control, the amount of fragile fruits falling down will fall into the unloading component below when the weighing reaches the system set amount, and the weighing is automatic, with good continuity and accuracy; the delivery device can stably deliver the fragile fruits that fall into the conveying channel to the location of the container;

[0069] (4) A number of partitions separate corresponding conveying channels, and the number of conveying channels corresponds to the number of upper push-down mechanisms. The outlet of each conveying channel corresponds to a container, and the fragile fruits after combined weighing are stably delivered to the container, ensuring the stability of the conveying of the fragile fruits to the specified weight in the container after the entire combined weighing; the push-down mechanism operates accordingly under the control of the controller. When the unloading assembly after the system assembly reaches the corresponding conveying channel, the push-down assembly at the corresponding position operates to pour the fragile fruits in the combined frame unloading assembly into the corresponding conveying channel, ensuring the continuous operation of the entire circulation system;

[0070] (5) Under the bottle feeding force of the bottle feeder, the container is sent to the delivery outlet corresponding to the conveying channel, and the fragile fruits falling from the conveying channel are caught in the container to realize automatic canning. The falling fragile fruits can accurately fall into the container, avoiding the fragile fruits falling outside the container after weighing, thereby ensuring the accuracy of the final canned weight; the can delivery device can continuously deliver the empty container to the bottle feeder, and under the guidance of the bottle feeder, the container accurately reaches the delivery outlet corresponding to the conveying channel to realize continuous canning.
