Description

Technical Field

[0001] The invention relates to the technical field of packaging machinery, and in particular to a double-station positioning case packing conveyor. Background Art

[0002] The automated packaging production line consists of the following process steps: automatic carton opening, automatic packing, and automatic sealing. After the carton is opened by the carton opener, it needs to be transported and fixed at the exact position of the packing station. The packing robot then packs the carton according to the set position coordinates, and finally transports it to the carton sealing machine for sealing. When there are two production lines for products of different specifications in the automated packaging workshop, each production line needs to be equipped with a carton opener, carton packer, and carton sealing machine. This not only has high equipment costs and large investments, but also increases the workload of repair and maintenance, and occupies a large amount of workshop space resources. Summary of the invention

[0003] The technical problem to be solved by the present invention is: in view of the shortcomings of the existing multiple independent packaging production lines, such as high cost, large investment and large space resource occupation, the online conveying structure is designed and modified to provide a double-station positioning packing conveyor that can realize the parallel operation of two production lines of products of different specifications and share a set of unpacking, packing and sealing equipment.

[0004] The double-station positioning packing conveyor comprises a machine frame, a double-station switching mechanism fixedly connected to the frame, a double-station conveying mechanism slidably connected to the double-station switching mechanism, and a controller for controlling the actions of the double-station switching mechanism and the double-station conveying mechanism, wherein:

[0005] The double-station switching mechanism includes: a guide rail fixed on the machine base and arranged perpendicular to the carton conveying direction, a driver fixed on the machine base and used to drive the double-station conveying mechanism to reciprocate, and a conflict buffer fixed on the machine base and used to limit the end position of the reciprocating motion of the double-station conveying mechanism;

[0006] The double-station conveying mechanism comprises: a slide slidably mounted on the guide rail and fixedly connected to the output end of the driver, a first conveyor and a second conveyor arranged side by side on the slide; the first conveyor and the second conveyor each comprise a frame, a plurality of conveying rollers arranged on the frame for conveying cartons, a lifting baffle arranged on the frame for blocking cartons, a translation clamping plate on the frame for fixing cartons, and three sets of position sensors arranged on both sides of the frame for sensing the position of cartons;

[0007] The input end of the controller is electrically connected to the three groups of position sensors respectively, and the output end of the controller is electrically connected to the conveying roller, the lifting baffle, the translation clamping plate and the driver respectively.

[0008] In order to realize the reciprocating translation of the double-station conveying mechanism on the machine base, the conveying channel formed by the first and second conveyors has been alternately aligned in the unpacking, packing and sealing equipment. The driver is a servo motor or a hydraulic cylinder, and the output shaft of the servo motor or the cylinder rod of the hydraulic cylinder is fixedly connected to the slide.

[0009] In order to limit the terminal position of the first and second conveyor-shaped translation, the abutment buffer comprises an angle steel piece and a tightening bolt fixed on the machine base, and an elastic rubber cap is sleeved on the tightening bolt.

[0010] In order to realize automatic control of carton conveying, the conveying roller is a motorized roller pivotally connected to the frame.

[0011] In order to stop and align the carton at the packing position, the lifting baffle includes a lifting motor installed on the frame and a baffle body fixedly connected to the output shaft of the lifting motor.

[0012] In order to achieve fixed positioning of the carton at the packing position, the translation clamp includes a clamp body slidably mounted on the frame and a translation motor for driving the clamp body to translate.

[0013] In order to realize a series of automatic controls such as starting the conveying after the carton enters, fixing the carton at the packing position, and alternating the conveyor after the carton is transported out, the position sensor is a photoelectric sensor, including a first sensor arranged at the upstream carton entrance end of the rack, a second sensor arranged at the position of the lifting baffle on the rack, and a third sensor arranged at the downstream carton exit end.

[0014] After the carton is sent out from the carton unpacking machine outlet to the conveyor, the first position sensor is electrically connected to the first input terminal of the driver, and the first input terminal of the driver is electrically connected to the motor in the conveyor roller and the lifting motor corresponding to the output terminal. The first position sensor generates an induction signal and transmits it to the controller, which drives the conveyor roller motor and the lifting motor to start, and the conveyor roller conveys the carton forward and the baffle body rises.

[0015] The carton is stopped when it is transported to the baffle body. The second sensor is electrically connected to the second input terminal of the driver. The corresponding output terminal of the second input terminal of the driver is electrically connected to the motor in the conveying roller and the translation motor. The second sensor generates an induction signal and transmits it to the controller. The controller drives the conveying roller motor to stop and the translation motor to start. The transport stops, the clamping body clamps the carton in place, and the packing robot packs the carton.

[0016] After the packing is completed, the baffle body and the clamp body return, and the conveyor roller continues to convey the carton to leave the conveyor and enter the entrance of the packaging machine. The third position sensor is electrically connected to the third input terminal of the driver, and the third input terminal of the driver corresponds to the output terminal and is electrically connected to the motor in the conveyor roller and the driver. The third position sensor generates an induction signal and transmits it to the controller. The controller drives the conveyor roller motor to stop and the driver to start, driving another conveyor to move horizontally into the conveying position and dock with the exit of the carton opener and the entrance of the carton sealer.

[0017] The double-station positioning case packing conveyor of the present invention realizes the parallel operation of two production lines of products with different specifications and the sharing of a set of unpacking, packing and sealing equipment by designing and modifying the online conveying structure, thereby overcoming the defects of the existing multiple independent packaging production lines such as high equipment cost, large investment, increased maintenance workload, and large occupation of workshop space resources, and is widely used in workshops with multiple independent packaging production lines for equipment modification and technology upgrade.

It is used to limit the end position of the first and second conveyors when they are aligned and translated. The conveying roller 35 is an electric roller pivotally connected to the frame 34. It is used to realize automatic control of carton conveying.

[0032] The lifting baffle 36 includes a lifting motor 361 mounted on the frame 34 and a baffle body 362 fixedly connected to the output shaft of the lifting motor 361. It is used to stop and align the carton at the packing position.
