Description

Technical Field

[0001] The present invention relates to the technical field of case packing machines, and in particular to a case packing machine with weighing and intelligent screening. Background Art

[0002] A case packer is a device that semi-automatically or automatically loads unpackaged or small-packaged products into transport packaging. Its operating principle is to arrange the products into a box (corrugated box, plastic box, pallet) in a certain arrangement and quantity, and then close or seal the box opening. According to the requirements of a case packer, it should be able to form the box (or open the box), measure the items, and pack the items. Some also have sealing or strapping functions.

[0003] During use, the cartoning machine in the existing technology is unable to screen the qualified status of raw materials, which may cause some unqualified products to be packed into the packaging box, resulting in the need to re-inspect the entire box of products, and unpack and repack them, and the number of boxes cannot be automatically adjusted according to the size of the packaging box. In order to solve the above problems, a cartoning machine with weighing and intelligent screening is needed. Summary of the Invention

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid blurring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0005] In view of the problems existing in the existing case packing machines, the present invention is proposed.

[0006] Therefore, the purpose of the present invention is to provide a case packing machine with weighing and intelligent screening. The machine grabs the raw materials through a suction plate, and then uses a first weighing sensor to detect the weight of the raw materials. When the weight is qualified, the case packing robot will put the raw materials into the box. When the weight of the raw materials is unqualified, the case packing robot will put the raw materials on the defective product conveyor belt, and the defective products will be transported to the defective product processing area through the defective product conveyor belt. The box weighing platform can be used to detect the weight of the empty box. After the detection is completed, the weight of the empty box is recorded by the central processor, and the size of the box is determined according to the weight. Different quantities of raw materials are loaded according to the size of the box. The raw materials are loaded into the box by the packing robot, and the box is weighed a second time through the packing weighing platform. When the box weight reaches the preset value, the box conveyor belt transports the box to the re-inspection weighing platform, and the box is re-inspected by the re-inspection weighing platform. When the re-inspected weight is qualified, the box conveyor belt transports the box to the sorting machine. The sorting machine transports the box to the first finished product conveyor belt or the second finished product conveyor belt according to the weight. When the re-inspected weight is unqualified, the raw materials are added to the box for a second time according to the weight difference.
