Description

Technical Field

[0001] The present invention relates to the field of automatic labeling technology, and in particular to an automatic labeling device for a casting production line. Background Art

[0002] In the current foundry industry, with the continuous expansion of production scale and the increasing requirements for product quality traceability and management, the labeling of foundry products such as aluminum ingots has become increasingly important. However, the traditional labeling method has many problems that need to be solved.

[0003] In the past, labeling work on casting production lines mainly relied on manual operation. Before casting production, workers need to print labels for the batch of products to be produced in advance, or print finished product labels after the products are packaged and weighed, and then label the aluminum ingots one by one. This manual labeling method is extremely inefficient. It not only consumes a lot of manpower and time, but also the labeling position is difficult to ensure accuracy and position deviation is prone to occur. At the same time, due to the uncertainty of manual operation, the firmness of label pasting is also uneven, and labels are prone to fall off, which not only affects the appearance of the product, but may also cause product information loss, causing great trouble to subsequent quality traceability and logistics management.

[0004] In addition, although there are some laser marking equipment on the market that can be used for product identification, these equipment have obvious limitations in the field of casting production. The laser marking speed is relatively slow and cannot meet the large-scale and high-efficiency production needs of the casting production line. Moreover, the laser-printed labels are poor in clarity and fineness, especially for some scenes that require printing fine information such as QR codes, it is difficult to achieve the ideal effect. In addition, after laser marking, the surface of aluminum products is prone to oxidation, causing the label to become blurred in a short time, affecting the reading of information. At the same time, the laser-printed labels are single in color and cannot meet the needs of some companies that have special requirements for the appearance of the label. More importantly, for products that require double-sided marking, the cost of laser marking is relatively high, which further limits its wide application in the casting industry.

[0005] It is worth noting that many downstream ingot product demand companies explicitly require that the ingot products they provide must be equipped with paper labels to facilitate information identification and recording in different environments. This makes it impossible to meet the needs of such customers by relying solely on laser marking technology. In order to meet customer requirements, non-ferrous metallurgical companies have to arrange special personnel for secondary labeling, which undoubtedly further increases the production costs and management difficulties of the companies.

[0049] The label supply mechanism includes a label printing head 240, a peeling mechanism 250 and a label retracting mechanism 260. The label retracting mechanism 260 includes a label backing paper recovery roll 263 and a label reel 265. The label reel 265 is wound with a label backing paper 261, and a label 262 is arranged on the label backing paper 261. The label reel 265 unwinds the label backing paper 261. The label backing paper 261 passes through the label printing head 240 and the peeling mechanism 250 in sequence. The label printing head 240 is used to print the data information of the aluminum ingot 500 on the label 262 on the label backing paper 261. The peeling mechanism 250 is used to peel off the label 262 after the data information is printed, and absorb the label 262 through the labeling mechanism, and rewind the label backing paper 261 after the label 262 is peeled off through the label backing paper recovery roll 263.

[0050] The labeling mechanism is disposed on one side of the peeling mechanism 250 on the label supply mechanism, and is used to absorb the peeled label 262 and attach the absorbed label 262 to one side of the aluminum ingot 500 .

[0051] When in use, the conveyor line 100 is responsible for conveying the aluminum ingot 500 to be labeled, the label reel 265 in the label supply mechanism on the labeling machine 200 unwinds the label backing paper 261, the label backing paper 261 passes through the label printing head 240 and the peeling mechanism 250 in sequence, the label printing head 240 prints the data information of the aluminum ingot 500 on the label 262, the peeling mechanism 250 peels off the label 262 after the data information is printed, and the labeling mechanism absorbs the peeled label 262 and attaches it to one side of the aluminum ingot 500, thereby realizing automatic labeling of the aluminum ingot 500 on the conveyor line. The automation of aluminum ingot labeling in the casting production line is realized, replacing manual labeling, improving labeling efficiency, and reducing labor costs and human errors.

[0052] In some embodiments, the label supply mechanism and the labeling mechanism are both disposed on the mounting seat 230, and the labeling mechanism is disposed on one side of the label supply mechanism. The label 262 is printed and peeled off by the label supply mechanism, and the peeled label 262 is sucked by the labeling mechanism on one side and attached to one side of the aluminum ingot 500;

[0053] The label printing head 240 adopts the Epson TM-H6000 model to print the data information of the aluminum ingot 500, wherein the data information of the aluminum ingot 500 includes inspection data, product weight data and other information.

[0054] In some embodiments, the peeling mechanism 250 includes a pressing block 252 and a rotating roller 253, one end of the pressing block 252 is arranged on one side of the rotating roller 253, the pressing block 252 and the rotating roller 253 are arranged in a gap, the label backing paper 261 passes through the pressing block 252 and the rotating roller 253, the other end of the pressing block 252 is rotatably arranged on the mounting seat 230 through a rotating shaft 254, and a tensioning mechanism is arranged on one side of the pressing block 252 for pushing one end of the pressing block 252 to rotate around the rotating shaft 254;

[0055] The tensioning mechanism includes a telescopic cylinder 255 fixedly mounted on the mounting seat 230, a telescopic rod 259 being slidably connected inside the telescopic cylinder 255, a push block 257 being arranged at the end of the telescopic rod 259, a spring 256 being sleeved on the telescopic rod 259, one side of the push block 257 being in contact with the clamping block 252, and being used for pushing the clamping block 252 to rotate around the rotating shaft 254, so that one end of the clamping block 252 is in contact with the rotating roller 253 through the label backing paper 261, and the side of the clamping block 252 in contact with the rotating roller 253 is arranged in an arc shape, and is adapted to the rotating roller 253.

[0056] When in use, the label backing paper 261 passes through the pressing block 252 and the rotating roller 253, and the telescopic cylinder 255 in the tensioning mechanism pushes the push block 257 through the internal telescopic rod 259 and the spring 256, so that the push block 257 pushes the pressing block 252 to rotate around the rotating shaft 254, so that one end of the pressing block 252 contacts the rotating roller 253 through the label backing paper 261, and the friction force is used to keep the label backing paper 261 in a tensioned state, which is convenient for subsequent label peeling and transportation. The tensioning mechanism ensures the tension of the label backing paper 261, ensures the stability of the label during transportation, and prevents the label backing paper 261 from loosening or running off, thereby improving the accuracy of label peeling and labeling.

[0057] In some embodiments, the stripping mechanism 250 further includes a stripping block 251, the stripping block 251 is provided with a rotating roller 253 and one side of a pressing block 252, and is used to strip the label 262 on the label backing paper 261, and a stripping plate 258 is fixedly installed on the side of the pressing block 252 close to the stripping block 251, and a gap is provided between the stripping plate 258 and the stripping block 251, and the label backing paper 261 passes through the gap between the stripping plate 258 and the stripping block 251, and the label 262 on the label backing paper 261 is stripped by the stripping block 251;

[0058] The cross section of the label stripping block 251 is arranged in a trapezoidal shape, and the contact end of the label stripping plate 258 and the label backing paper 261 is arranged in an arc shape.

[0059] When in use, the label backing 261 passes through the gap between the label stripping plate 258 and the label stripping block 251. Since the cross section of the label stripping block 251 is set in a trapezoidal shape, and the contact end of the label stripping plate 258 and the label backing 261 is set in an arc shape, when the label backing 261 passes, the label 262 is separated from the label backing 261 under the action of the label stripping block 251 and the label stripping plate 258, and the label is stripped. The special shape design of the label stripping block 251 and the label stripping plate 258 makes the label stripping smoother and more thorough, reduces the situation of label residue and damage, and improves the success rate and quality of label stripping.

[0060] In some embodiments, a blow pipe 270 is provided at the front side of the label stripping block 251, and a plurality of second air holes 272 are provided on the blow pipe 270. The plurality of second air holes 272 are opened toward the label stripping block 251, and are used to blow dry the label 262 on the label backing paper 261, and blow the label 262 to make it adsorbed on the labeling mechanism;

[0061] A second connector 271 is disposed at one end of the air blowing pipe 270 , and the second connector 271 is connected to an air source.

[0062] When in use, the air blowing tube 270 is connected to the air source through the second joint 271, and the air provided by the air source is blown out from the plurality of second air holes 272 on the air blowing tube 270 toward the label stripping block 251 to dry the label 262 on the label backing paper 261, thereby removing impurities such as moisture or oil on the surface of the label. At the same time, the blowing of the air makes it easier for the label 262 to be adsorbed on the labeling mechanism. Blowing the label dry can prevent the label from being loosely adhered due to moisture or oil, thereby improving the quality of the label's adhesion. At the same time, the blowing of the air helps the label to be quickly and accurately adsorbed on the labeling mechanism, thereby further improving the labeling efficiency.

[0063] In some embodiments, the label retracting mechanism 260 further includes a plurality of tensioning rollers 264 , which are disposed on the mounting seat 230 and are used to allow the label backing paper 261 to pass between the label printing head 240 and the peeling mechanism 250 .

[0064] When in use, a plurality of tension rollers 264 are mounted on the mounting base 230. When the label backing paper 261 passes between the label printing head 240 and the peeling mechanism 250, the tension rollers 264 play a role in tensioning and guiding the label backing paper 261, so that the label backing paper 261 remains flat and stable during the conveying process. The label backing paper 261 is ensured to be conveyed smoothly between the label printing head 240 and the peeling mechanism 250, and wrinkles, distortions, etc. of the label backing paper 261 are avoided, thereby ensuring the accuracy of label printing and peeling.

[0065] In some embodiments, the labeling mechanism includes a suction component and a pushing component, the suction component includes a push plate 222, a suction cup 224 is provided on one side of the push plate 222, a first joint 225 is provided on the other side of the suction cup 224, the first joint 225 is connected to an air source, and a plurality of first air holes 226 are provided on the push plate 222 for sucking the label 262 peeled off by the peeling mechanism 250;

[0066] One side of the label 262 is a label information side, and the other side is an adhesive side. When the push plate 222 absorbs the label 262, the label information side of the label 262 is adsorbed on one side of the push plate 222. The push plate 222 drives the label 262 to one side of the aluminum ingot 500 through the pushing component, and the label 262 is adhered to the aluminum ingot 500 through the adhesive side of the label 262.

[0067] When in use, the push plate 222 in the suction assembly is connected to the air source through the suction cup 224 and the first joint 225 on one side. When the air source provides negative pressure, the first air holes 226 on the push plate 222 generate suction to absorb the label 262 peeled off by the peeling mechanism 250, and the label information surface of the label 262 is adsorbed on one side of the push plate 222. Then the push cylinder 221 in the push assembly pushes the telescopic rod to move, driving the push plate 222 and the label 262 to move to one side of the aluminum ingot 500, and the label 262 is adhered to the aluminum ingot 500 through the adhesive surface of the label 262. Sucking the label through the suction cup is simple and convenient to operate, and can quickly and accurately absorb and transfer the label, thereby improving the efficiency and accuracy of labeling.

[0068] In some embodiments, the pushing assembly includes a pushing cylinder 221, which is fixedly mounted on the mounting seat 230, and the end of the telescopic rod of the mounting seat 230 is fixedly connected to the suction cup 224. The pushing cylinder 221 is connected to an air source to push the telescopic rod to move, so that the push plate 222 pushes the label 262 to move, so that it is adsorbed on the aluminum ingot 500;

[0069] A wire-receiving crawler 223 is disposed on one side of the pushing cylinder 221 , and the wire-receiving crawler 223 is used for arranging cables and air pipes.

[0070] When in use, the push cylinder 221 is fixedly installed on the mounting seat 230, and the end of its telescopic rod is fixedly connected to the suction cup 224. When the air source connected to the push cylinder 221 provides power, the push cylinder 221 pushes the telescopic rod to move, thereby driving the push plate 222 and the label 262 to move to one side of the aluminum ingot 500 for labeling. After the label 262 is posted, the push plate 222 applies pressure to the entire surface of the posted label 262 to ensure the firmness of the posting and effectively prevent the label 262 from falling off. The wire-reeling track 223 is used to arrange cables and air pipes to make them neat and orderly and avoid clutter. The push cylinder 221 provides stable and reliable power and can accurately control the attachment position of the label. The wire-reeling track 223 makes the arrangement of cables and air pipes of the equipment more standardized, which is convenient for the maintenance and management of the equipment.

[0071] In some embodiments, the label supply mechanism is provided with a label supply mechanism dust cover 210, and the labeling mechanism is provided with a labeling mechanism dust cover 220. The label supply mechanism dust cover 210 and the labeling mechanism dust cover 220 are respectively covered on the label supply mechanism and the labeling mechanism to prevent high temperature, oil, dust and other impurities in the casting production line from entering the label supply mechanism and the labeling mechanism, affecting the printing, peeling and attachment effects of the label. The label supply mechanism and the labeling mechanism are effectively protected, the impact of the external environment on the equipment is reduced, the service life of the equipment is extended, and the stability and reliability of the equipment are improved.

[0072] In some embodiments, visual inspection equipment 300 is provided on both sides of the conveyor line 100, and the visual inspection equipment 300 includes at least one position acquisition camera for detecting the position information of the aluminum ingot 500 on the conveyor line 100. A control electrical box 400 is provided on one side of the conveyor line 100 for controlling the conveyor line 100, the labeling machine 200 and the visual inspection equipment 300 to work together.

[0073] When in use, the position acquisition camera in the visual inspection device 300 detects the position information of the aluminum ingot 500 on the conveyor line 100 and transmits the signal to the control box 400. The control box 400 controls the conveyor line 100, the labeling machine 200 and the visual inspection device 300 to work together according to the received position information, so that the label can be accurately attached to the specified position of the aluminum ingot 500. Through the coordinated work of the visual inspection and control system, the precise positioning of the label attachment position is achieved, the labeling quality and accuracy are improved, and the labeling requirements of aluminum ingots of different sizes and shapes are met.

[0074] An automatic labeling device for a casting production line is used:

[0075] The conveyor line 100 is started, and the aluminum ingot 500 to be labeled is conveyed at the set speed and trajectory. The position acquisition camera in the visual inspection device 300 detects the position information of the aluminum ingot 500 on the conveyor line 100 in real time, and transmits the signal to the control box 400. The control box 400 controls the labeling machine 200 to start working according to the information;

[0076] The label reel 265 unwinds the label backing paper 261, which passes through a plurality of tensioning rollers 264 in sequence to ensure its flatness and stability during the conveying process, and then passes through the label printing head 240, which prints the label 262 according to the data information of the aluminum ingot 500.
