[0001] The utility model relates to the technical field of weighing and coding of assembly line packaging boxes, in particular to a packaging weighing and coding device. Background Art

[0002] After the products are packed, the boxes need to be weighed and unqualified products that do not reach the standard weight need to be removed to ensure the quality of the company's products. The boxes can then be coded.

[0003] At present, the weighing and rejection process is mainly carried out through a belt-type weighing platform, and then a rejection device is used to reject unqualified products. The rejection devices on the market mainly include air-blowing type, flip-plate type, push rod type, etc. For these rejection devices, the air-blowing type cannot be used to reject large and heavy products, the flip-plate type is difficult to connect with the subsequent production line in the assembly line, and the push rod type has high requirements for the positioning of unqualified products. Improper coordination of weighing and rejection on the assembly line often leads to unqualified products entering the next process. The existing push rod type conveyor belt weighing and rejection devices lack a calibration mechanism.

[0004] In addition, during the production, transportation and packaging of product packaging boxes, dust will inevitably adhere to the surface. When entering the inkjet printing process, the dust will adhere to the inkjet printer's nozzle and cause nozzle blockage. At present, manual cleaning is mainly used to solve the nozzle blockage problem, which not only affects production efficiency and reduces production capacity, but also increases labor costs and is very inconvenient to operate.

[0005] Therefore, it is necessary to improve and optimize the existing weighing and inkjet printing device so that it can better meet user needs. Therefore, it is necessary to improve the existing technology. Utility Model Content

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0022] See Figure 1 As shown, an embodiment of the utility model proposes a packaging weighing and inkjet coding device, which includes a main belt-type weighing platform 1, a first conveying roller 2, a second conveying roller 3, a pushing assembly 4, a conveyor belt 5, and an inkjet printer 6.

[0023] The conveyor belt 5, the belt-type weighing platform 1 and the first conveyor roller 2 are connected in sequence from front to back.

[0024] The belt weighing platform 1 is a conventional belt weighing platform, on which a gravity sensor and an electric transmission belt are arranged.

[0025] The first conveying roller 2 is a powered roller, which is horizontally arranged and connected to the belt-type weighing platform 1 .

[0026] The inkjet printer 6 is arranged on one side of the first conveying roller 2 .

[0027] The conveyor belt 5 is provided with a brush assembly and a support plate 51 for constraining the boundary of the product on the conveyor belt on the same side as the inkjet printer 6 of the first conveyor roller 2.

[0028] The backing plate 51 is a vertically arranged unpowered roller, and the conveyor belt is also provided with a finishing assembly for allowing the products on it to be conveyed against the backing plate. In a preferred embodiment, the finishing assembly is a trumpet-shaped baffle 52 arranged at the head of the conveyor belt.

[0029] The brush assembly includes a brush head 54 mounted on a frame 53, and the brush head 54 is located above the support plate 51. On a horizontal projection plane, the brush head 54 passes through the support plate 51 into the conveying area of ​​the conveyor belt 5, and corresponds to the nozzle position of the inkjet printer 6.

[0030] The second conveyor roller 3 is a non-powered roller, which is arranged on one side of the first conveyor roller 2 and is perpendicular to the axis of the first conveyor roller 2. The second conveyor roller 3 is arranged obliquely downward, and its upper end is flush with the conveying surface of the first conveyor roller 2. In addition, bell-shaped baffles 31 are arranged on both sides of the second conveyor roller 3.

[0031] The push assembly 4 is a conventional push rod type rejection mechanism, including a push block 41 and a driving mechanism for driving the push block to intermittently extend to push the product on the first conveyor roller 1 to the second conveyor roller 3. In a preferred embodiment, the driving mechanism is a cylinder 42, and the push block 41 is fixedly connected to the piston of the cylinder 42. Of course, push rod devices of other structures such as electric push rods can also be applied here.

[0032] In addition, the packaging weighing and coding equipment also includes a first photoelectric sensor 7, a second photoelectric sensor 8 and a PLC module. The first photoelectric sensor 7 senses toward the first conveyor roller 2 located behind the second conveyor roller 3 to detect whether there is a product passing on the first conveyor roller; the second photoelectric sensor 8 senses toward the second conveyor roller 3 to detect whether there is a product passing on the second conveyor roller 3.

[0033] In a preferred embodiment, the first photoelectric sensor 7 includes a diffuse reflection sensor and a reflector, which are installed on both sides of the first conveyor roller 2 and located behind the second conveyor roller 3.

[0034] The PLC module connects the conveyor belt 5, the first photoelectric sensor 7, the second photoelectric sensor 8, the gravity sensor and the electric transmission belt of the belt-type weighing platform 1, the first conveyor roller 2 and the driving mechanism.

[0035] The gravity sensor continuously collects and sends product weight data to the PLC module. When the product weight data is lower than the threshold, the PLC module delays and controls the pushing block 41 of the pushing assembly 4 to extend, pushing the unqualified products from the first conveyor roller 1 to the entrance of the second conveyor roller 3.

[0036] If the unqualified products are normally rejected, the first photoelectric sensor does not detect that there are products passing through within the set time, while the second photoelectric sensor detects that there are products passing through. The packaging weighing and coding equipment continues to allow, and the unqualified products are stored in the second conveyor roller 3 to wait for processing.

[0037] If the unqualified products are not removed normally, the first photoelectric sensor can detect the passing of products at the set time, while the second photoelectric sensor cannot detect the passing of products. At this time, the PLC module controls the electric conveyor belt, conveyor belt 5, and first conveyor roller 2 of the belt weighing platform 1 to stop to prevent unqualified products from flowing into the next process. After the operator handles it, the operation is resumed.

[0038] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model proposes a packaging weighing and coding equipment, in which a brush is arranged to pre-clean the coding part of the packaging box, which greatly reduces the cycle of cleaning and unblocking the nozzle, and realizes the rejection and verification functions by arranging two rollers and two photoelectric sensors, thereby improving the rejection efficiency and success rate of products on the assembly line.
