Description

[Technical field]

[0001] The invention belongs to the technical field of automatic labeling equipment, and in particular relates to automatic labeling equipment for water transfer labels of utensil products, a labeling production line and a labeling method. [Background technology]

[0002] The labeling machine is a common equipment in the non-standard automation industry. It is a device that uses a labeling head to take the label and then sticks the label to the product. At present, the conventional label is peeled off from the release paper and the adhesive surface of the label is directly pasted on the surface of the target product using a suction nozzle. This type of label is suitable for product surfaces with a certain surface roughness requirement. However, for the surface of glass bottles, in order to ensure the firmness of the label, a specific label is generally used. The label has a layer of backing paper. Before pasting, it needs to be soaked in water to peel the label from the backing paper and then pasted.

[0003] Patent CN218892817U in the prior art discloses a fully automatic labeling equipment for round bottles, which uses a conveyor line to continuously supply bottles in a row, and then uses a loading and transporting mechanism to transport a group of bottles to a water spraying station and a labeling station in turn. At the water spraying station, a water spraying unit is used to spray water on the labeling position on the bottle. At the labeling station, a label feeding module, a plurality of arranged label immersion modules, a bottom paper rubbing module and a labeling carrier are sequentially arranged. A label taking and transporting module, a label placing and transporting module and a labeling pressing module are arranged above. The label taking and transporting module takes out a group of labels from the label feeding module and places them in the label immersion module. The label placing and transporting module takes out the immersed labels from the label immersion module and then transports them to the bottom paper rubbing module position to remove the bottom paper and then moves them to the top of the labeling carrier, and pastes the labels on the bottles in the labeling carrier. Finally, the labels are pressed by the label pressing module to complete the labeling. The equipment has the following disadvantages:

[0004] (1) A group of bottles are transported from the water spraying station to the labeling station and then to the unloading conveyor line through the loading and transporting mechanism. The bottle position transfer speed is slow, which affects the labeling efficiency of the entire equipment;

[0005] (2) The label handling module is driven by the linear transfer module to sequentially take out labels, rub the base paper and apply labels. The walking rhythm also has certain limitations and cannot meet the labeling requirements of higher rhythms;

[0006] (3) The label pressing module can only perform the label pressing operation after the label handling module completes the labeling action. There is a waiting time, which reduces the labeling speed.

[0007] Therefore, it is necessary to provide a new automatic labeling equipment, labeling production line and labeling method for utensil products to solve the above technical problems. [Summary of the invention]

[0026] S1. The feeding conveyor line conveys the bottles for feeding, and the bottles are introduced into the corresponding labeling equipment by the feeding mechanisms in the multiple labeling equipment;

[0027] S2. Complete bottle labeling in various labeling equipment:

[0028] S21, the feeding mechanism includes an angle recognition and adjustment module; the angle recognition and adjustment module includes a rotating support seat and a first camera arranged above or below the rotating support seat; the bottle is placed on the rotating support seat in a standing state, the first camera takes a picture of the bottle to obtain the initial position of the labeling surface on the bottle, and the rotating support seat is driven to rotate with the bottle according to the initial position information, and the labeling surface is rotated and adjusted to a set angle position;

[0034] S3, the unloading conveyor line receives all the bottles with labels output by the labeling equipment and unloads them uniformly.

[0035] Compared with the prior art, the beneficial effects of the automatic labeling equipment, labeling production line and labeling method for utensil products of the present invention are: greatly improving the labeling efficiency of water transfer labels and meeting the process requirements of higher production rhythm.

[0036] Specific:

[0037] (1) The original round bottle labeling equipment cannot realize the parallel connection of multiple labeling equipment, resulting in limited labeling efficiency. This solution optimizes the structure of the labeling equipment and adopts a disc-type rotating structure to transport bottles for position switching between various workstations. It cooperates with the loading and unloading conveyor lines and the loading and unloading mechanisms in the labeling equipment, so that multiple labeling equipment can be connected in parallel, thereby greatly improving the labeling efficiency of water transfer labels for container products;

[0038] (2) In the original round bottle labeling equipment, the label placement and label pressing operations must be performed in sequence and cannot be performed simultaneously, which limits the labeling efficiency. In the labeling equipment of this solution, a turntable transfer mechanism is used to realize a disc-type conveying method, and the bottles are conveyed to transfer between the loading station, the label placement station, the label pressing station and the unloading station. The operations of each station can be performed simultaneously, and the label placement operation and the label pressing operation are separated and divided into two stations for simultaneous operation, which further improves the labeling efficiency;

[0039] (3) At the label placement station, the structure of the label soaking module is optimized. The label soaking module is arranged on the second direction side of the label feeding module and has a plurality of soaking components. Each soaking component soaks only one label. The plurality of soaking components are arranged along the first direction, shortening the transfer path of the soaking and transporting module from the label feeding module to the soaking component after the label is adsorbed. On the one hand, the overall space occupation of the label feeding and pasting mechanism is reduced, and on the other hand, the production cycle is improved;

[0040] (4) At the label pressing station, the water-absorbing strip circulation feeding module is optimized. By configuring two material roll supply and receiving components, a supply and receiving structure with one unwinding and one rewinding is realized. A drying box is configured on the material strip inlet and outlet sides of the two material roll supply and receiving components. After the water-absorbing strip absorbs water and before it is rewound, it is dried with hot air so that the water-absorbing strip can be rewound in a dry state to achieve recycling.

[Specific implementation method]

[0067] Embodiment 1:

[0068] Please refer to Figure 1-Figure 15The present embodiment is an automatic labeling production line 100 for water transfer labels for utensil products, which includes a loading conveyor line 1 and a unloading conveyor line 2 arranged in parallel, a loading and bottle separation mechanism 3 arranged in sequence along the loading conveyor line 1, and a plurality of labeling devices 4.

[0069] In this embodiment, by sequentially arranging a plurality of labeling devices 4 along the feeding conveyor line 1, a plurality of bottles can be synchronously labeled at the same time, thereby improving the labeling production efficiency. Each labeling device 4 is provided with a feeding mechanism 41 for transferring bottles on the feeding conveyor line 1 to the labeling device 4, and a unloading mechanism 42 for transferring the labeled bottles from the labeling device 4 to the unloading conveyor line 2. The feeding conveyor line 1 supplies bottles to the plurality of labeling devices 4, and the unloading conveyor line 2 receives the labeled bottles output by all the labeling devices 4 and outputs them uniformly.

[0070] In order to prevent the bottles from colliding with each other on the feeding conveyor line 1 and causing the risk of damage, the bottle feeding in this embodiment is carried out by having the operator place the bottles one by one on the feeding bottle separation mechanism 3, and then using the feeding bottle separation mechanism 3 to output the bottles to the feeding conveyor line 1 at a certain interval. Therefore, the bottles input to the feeding conveyor line 1 will have a certain interval, which greatly reduces the risk of damage caused by collision. In other embodiments, the bottles can also be directly placed on the feeding conveyor line 1 in an interval manner by an operator or an automatic manipulator.

[0071] In this embodiment, the loading and bottle separating mechanism 3 includes a first motor 31, a first turntable 32 driven by the first motor 31 to rotate around the Z axis, a plurality of first carriers 33 arranged in a ring on the first turntable 32, and a limit stop bar 34 fixedly arranged on the outer periphery of the first turntable 32. The limit stop bar 34 is an unclosed circular ring structure and a discharge port 35 is formed in the unclosed section. The discharge port 35 is connected to the loading conveyor line 1. A guide plate 36 is provided at the discharge port 35 to guide the bottles 200 in the first carrier 33 moved to this place on the first turntable 32 into the loading conveyor line 1. A plurality of first carriers 33 are arranged at equal angles on the circumferential edge of the first turntable 32. The first carrier 33 has a first carrying groove 331 for carrying the bottle 200. The side of the first carrier 33 away from the center of the first turntable 32 is set as an open structure and is formed with a disengagement port 332. When the first carrier 33 moves to the discharge port 35, the bottle 200 in the first carrier 33 is guided by the guide plate 36 to disengage from the first carrier 33 from the disengagement port 332, and then is output from the discharge port 35 to the loading conveyor line 1.

[0072] The limit stop bar 34 is arranged around the top of the first turntable 32, and the area around the limit stop bar 34 body forms a manual loading area or a robot automatic loading area; the limit stop bar 34 is used to limit and block the bottle 200 on the first carrier 33 within the loading area to prevent the bottle 200 from sliding out of the escape port 332 in the first carrier 33 as the first turntable 32 rotates.

[0073] The labeling device 4 includes a turntable transfer mechanism 43, a feeding mechanism 41, a label feeding and pasting mechanism 44, a label pressing mechanism 45 and a discharge mechanism 42 which are sequentially arranged around the turntable transfer mechanism 43. The feeding mechanism 41 is used to import bottles from the feeding conveyor line 1 and transport them to the turntable transfer mechanism 43; the turntable transfer mechanism 43 is used to carry the bottles and move them to the subsequent mechanisms in sequence; the label feeding and pasting mechanism 44 is used to complete label feeding, water soaking, rubbing off the base paper and label pasting; the label pressing mechanism 45 is used to press the label firmly; the discharge mechanism 42 is used to export the labeled bottles to the discharge conveyor line 2. The turntable transfer mechanism 43 is used to realize the circulation of bottles between various workstations, so that subsequent workstations can operate simultaneously, thereby improving the labeling efficiency; in addition, the entire process of bottle labeling is divided into four main operations: loading, label placement, label pressing, and unloading. The loading mechanism 41, the label feeding and pasting mechanism 44, the label pressing mechanism 45, and the unloading mechanism 42 are configured accordingly, so that the two key actions of label placement and label pressing can be performed simultaneously, further improving the labeling production efficiency.

[0074] The turntable transfer mechanism 43 includes a second motor 431, a second turntable 432 driven by the second motor 431 to rotate around the Z axis, and a plurality of second carriers 433 arranged in an annular manner on the second turntable 432. The plurality of second carriers 433 are arranged at equal angles on the circumferential edge of the second turntable 432 and have second bearing grooves 4331 for bearing the bottles 200. The bottles 200 are placed in the second bearing grooves 4331 in a semi-lying state, so that the labeling surface 201 on the bottle 200 is in a horizontal state, so as to better paste the label.

[0075] The feeding mechanism 41 includes an angle recognition and adjustment module 411, a feeding input module 412, and a feeding transport module 413. The angle recognition and adjustment module 411 is mainly used to recognize the circumferential angle position of the bottle 200 when it is fed, so as to obtain the angle position of the labeling surface 201, and then adjust the labeling surface 201 to the set angle position; the feeding input module 412 is used to guide the bottle 200 on the feeding conveyor line 1 into the angle recognition and adjustment module 411; the feeding transport module 413 is used to transport the bottle 200 after the angle is adjusted to the second turntable 432, and place it in the second carrier 433 in a set lying posture.

[0076] The angle recognition and adjustment module 411 includes a rotating support seat 4111, a first camera 4112 disposed below the rotating support seat 4111, and a third motor 4113 driving the rotating support seat 4111 to rotate around the Z axis. The rotating support seat 4111 is provided with an escape hole (not marked in the figure) that passes through from top to bottom, so that the first camera 4112 can take pictures of the bottle on the rotating support seat 4111. The first camera 4112 takes pictures of the bottle 200 through the escape hole to obtain the initial position of the labeling surface 201. The third motor 4113 adjusts the rotating support seat 4111 to rotate with the bottle 200 according to the initial position information, and adjusts the labeling surface 201 on the bottle 200 to a set angle position, so that when the loading and transporting module 413 transports the bottle to the second carrier 433, the labeling surface 201 is placed facing upward.

[0077] In other embodiments, the first camera 4112 may also be disposed above the rotating support seat 4111. If disposed above the rotating support seat 4111, the rotating support seat 4111 does not need to have the avoidance through hole.

[0078] In this embodiment, the feeding input module 412 includes a branch feeding channel 4121 connected to the feeding channel in the feeding conveyor line 1 at the side of the feeding conveyor line 1, a material shifting plate 4122 for transferring the bottle 200 from the feeding conveyor line 1 to the branch feeding channel 4121, and a first two-axis driving assembly 4123 for driving the material shifting plate 4122 to move horizontally and move up and down along the Z axis; the rotating support seat 4111 is embedded at the end of the branch feeding channel 4121. The first two-axis driving assembly 4123 drives the material shifting plate 4122 to move, shifting the bottle 200 from the feeding conveyor line 1 to the branch feeding channel 4121, and the bottle 200 is pushed to the rotating support seat 4111 in sequence to realize feeding and conveying.

[0079] In other embodiments, the loading input module 412 may be a two-axis handling robot that directly grabs bottles from the loading conveyor line 1 and places them in the rotating support seat 4111 .

[0080] The loading and handling module 413 includes a second two-axis driving assembly 4131 for horizontal driving and Z-axis up and down movement, a first cylinder 4132 arranged at the movable end of the second two-axis driving assembly 4131, a first support plate 4133 driven by the first cylinder 4132 to rotate around the horizontal axis, and a first clamping claw assembly 4134 fixed on the first support plate 4133. The second two-axis driving assembly 4131 drives the first clamping claw assembly 4134 to clamp the bottle 200 in a standing state on the rotating support seat 4111, and then moves it to the top of the second turntable 432, and drives the first clamping claw assembly 4134 to rotate around the horizontal axis by a set angle through the first cylinder 4132, so that the bottle 200 is in an inclined posture of a set angle, and then placed in the second carrier 433, completing the loading of the bottle in a specific posture.

[0081] The label feeding and pasting mechanism 44 includes a label feeding module 441, a label soaking module 442 located at one side of the label feeding module 441, a soaking and transporting module 443 that sucks the label in the label feeding module 441 and places it in the label soaking module 442 for soaking, a label pasting robot 444 that sucks the soaked label in the label soaking module 442, a base paper removal module 445 arranged within the activity range of the label pasting robot 444, a second camera 446 for obtaining the label position information on the label pasting robot 444, and a third camera 447 for obtaining the position information of the labeling surface 201 on the bottle to be labeled. The immersion and handling module 443 absorbs the dry label in the label feeding module 441, and then places it in the label immersion module 442 for immersion in water. After the set soaking time, the label pasting robot 444 takes it out, and then moves it to the top of the base paper removal module 445, and cooperates with the base paper removal module 445 to remove the base paper on the label; then moves it to the top of the second camera 446, and obtains the label position information on the label pasting robot 444 through the second camera 446. At the same time, the second carrier 433 carries the bottle and rotates with the second turntable 432 to the position of the label feeding and pasting mechanism 44. The third camera 447 is located above the second carrier 433 at this position. The label pasting robot 444 obtains the position information of the labeling surface 201 on the bottle 200 through the third camera 447. In combination with the label position information obtained by the second camera 446 and the labeling surface position information obtained by the third camera 447, the label pasting robot 444 accurately pastes the label on the labeling surface 201 to complete the preliminary labeling.

[0082] The label feeding module 441 includes a second support plate 4411, at least one label bin 4412 disposed on the second support plate 4411, a second cylinder 4413 driving the second support plate 4411 to switch positions between the label replenishment position and the label feeding position, a material separation spring piece group 4414 disposed at the label feeding position to assist in the separation of labels in the label bin 4412, and a lifting assembly 4415 disposed at the label feeding position to lift the labels in the label bin 4412 upward. In this embodiment, two groups of label feeding modules 441 are provided to ensure gapless continuous feeding, and two label bins 4412 are provided in each label feeding module 441. In other embodiments, the number of label feeding modules 441 and the number of label bins 4412 in each label feeding module 441 can be flexibly set. The dividing spring piece group 4414 is fixedly arranged at the label feeding position. After the label silo 4412 moves to the label feeding position along with the second support plate 4411, the dividing spring piece group 4414 is just located at the top outlet of the label silo 4412. When the immersion and transportation module 443 absorbs the label 300 in the label silo 4412, the dividing spring piece group 4414 prevents the labels below from sticking together, thereby ensuring that the immersion and transportation module 443 absorbs only one label at a time.

[0083] The label soaking module 442 is arranged on one side of the label feeding module 441 along the second direction. Figure 7 As shown in . The label soaking module 442 includes a first support seat 4421, a heating pad 4422 arranged on the first support seat 4421, a water tank 4423 arranged on the heating pad 4422, and a plurality of soaking components 4424 arranged along the first direction, and the first direction is perpendicular to the second direction. The water tank 4423 is connected to a water circulation device (not shown in the figure), and the water is automatically replenished according to the water level in the water tank 4423 through the water circulation device, and the water in the water tank 4423 is replaced regularly. The water in the water tank 4423 is heated and heated by the heating pad 4422 to meet the requirements of the label soaking process. By arranging a plurality of soaking components 4424 along the first direction, on the one hand, multiple labels can be soaked at the same time, and each soaking component 4424 is responsible for soaking a label, and each soaked label can be taken away; on the other hand, the plurality of soaking components 4424 are arranged along the first direction, and compared with the original arrangement of a plurality of soaking components along the second direction, the movement path of the soaking and handling module 443 in the second direction can be shortened, the beat can be improved, and the space occupation of the equipment can be reduced.

[0084] The soaking component 4424 can adopt a structure such as the "soaking mechanism 522" in the patent CN218892817U in the prior art, and this embodiment does not limit its structure.

[0085] The immersion and transport module 443 includes a third two-axis driving assembly 4431 for realizing driving in the second direction and the first direction, a third support plate 4432 arranged at the movable end of the third two-axis driving assembly 4431, a third cylinder 4433 fixed on the third support plate 4432, and a first suction nozzle 4434 driven by the third cylinder 4433 to move up and down.

[0086] The label sticking robot 444 is a multi-axis manipulator, and a second suction nozzle (not shown in the figure) for adsorbing labels is arranged at its movable end. In this embodiment, the multi-axis manipulator is a SCARA robot.

[0087] The bottom paper removal module 445 includes a bottom paper suction nozzle 4451 for sucking the bottom paper and a bottom paper collection box 4452 for collecting the bottom paper.

[0088] In order to further improve the labeling efficiency, in this embodiment, two labels are designed on a label (i.e., the label after removing the backing paper), and two label suction nozzles are provided in the label pasting robot 444, which suck the two labels on a label at one time and paste them on the two bottles 200 in turn.

[0089] The label pressing mechanism 45 includes a pressing head 451 and an electric cylinder 452 for driving the pressing head 451 to move up and down, and also includes a water absorbing strip circulation feeding module 453 which is blocked between the pressing head 451 and the label when the pressing head 451 presses the label. The pressing head 451 is made of silicone.

[0090] The pressing head 451 and the electric cylinder 452 form a set of pressing modules. In this embodiment, two sets of the pressing modules are provided to press the labels on two bottles 200 at the same time.

[0091] In this embodiment, the water-absorbing strip circulation feeding module 453 includes a first material roll supply and receiving component 4531 and a second material roll supply and receiving component 4532, a first guide roller group 4533 and a second guide roller group 4534. The water-absorbing strip material belt 400 of the first material roll supply and receiving component 4531 (or the second material roll supply and receiving component 4532) is wound in sequence through the first guide roller group 4533, the second guide roller group 4534, the first guide roller group 4533 and finally returns to the second material roll supply and receiving component. In the material assembly 4532 (or the first material roll supply and receiving assembly 4531); the absorbent strip material belt 400 wound around the second guide roller group 4534 forms a horizontal absorbent sheet 401 under the pressing head 451. When the pressing head 451 moves downward to press the label, the absorbent sheet 401 is pressed downward at the same time. The pressing head 451 presses the label through the absorbent sheet 401, and the absorbent sheet 401 is used to absorb excess water on the label, which helps to reliably and effectively stick the label to the bottle.

[0092] The water-absorbing strip circulation feeding module 453 also includes a second support seat 4535, a movable support plate 4536 slidably disposed on the second support seat 4535, and a counterweight assembly 4537 for pulling the movable support plate 4536 upward, and a second guide roller group 4534 is disposed on the movable support plate 4536. By disposing the second guide roller group 4534 on the movable support plate 4536, the water-absorbing strip material belt 400 is tensioned by utilizing the gravity of the second guide roller group 4534 and the movable support plate 4536, so that the water-absorbing strip material belt 400 is kept in a tensioned state. After the pressing head 451 presses the absorbent strip downward to complete the label pressing, the pressing head 451 will rise to a high position. At this time, the downward pressure on the absorbent strip is cancelled. Under the action of the counterweight assembly 4537, the movable support plate 4536 is pulled up to the initial height. The first material roll supply and receiving assembly 4531 or the second material roll supply and receiving assembly 4532 can rewind the material to straighten the absorbent strip 400 again and realize the transportation of the absorbent strip, so that the subsequent drying area is aligned with the pressing head 451 for the next round of label pressing and water absorption.

[0093] The first material roll supply and receiving assembly 4531 , the second material roll supply and receiving assembly 4532 and the first guide roller group 4533 are installed on the second support seat 4535 .

[0094] In order to realize the recycling of the water-absorbing strip material belt 400, the present embodiment optimizes the design of the water-absorbing strip recycling supply module 453. Specifically, a drying box 4538 is provided between the first material roll supply and receiving component 4531 and the first guide roller group 4533, and between the second material roll supply and receiving component 4532 and the first guide roller group 4533. The water-absorbing strip material belt 400 passes through the drying box 4538, and is dried by the drying box 4538 and then rolled up at the end of the first material roll supply and receiving component 4531 or the end of the second material roll supply and receiving component 4532. After the dried water-absorbing strip material belt on the first material roll supply and receiving component 4531 (or the second material roll supply and receiving component 4532) is used up, the second material roll supply and receiving component 4532 (or the first material roll supply and receiving component 4531) can be made to output the dried water-absorbing strip material belt in reverse to realize recycling.

[0095] In other embodiments, the water absorption strip circulation feeding module 453 may also adopt a structure such as the "labeling pressing module 56" in the prior art patent CN218892817U, wherein the specific number of "labeling silicone pressure heads 565" may be set according to demand, for example, two may be set.

[0096] The unloading mechanism 42 includes a fourth axis driving assembly 421 for horizontal driving and Z axis up and down driving, a fourth support plate 422 provided at the movable end of the fourth axis driving assembly 421, and a second clamping jaw assembly 423 fixed on the fourth support plate 422. In order to ensure that the bottle on the second clamping jaw assembly 423 can stand stably on the unloading conveyor line 2, a first side limit plate 424 is provided on the fourth support plate 422 against one side of the bottle, and the unloading mechanism 42 also includes a second side limit plate 425 against the other opposite side of the bottle and a fourth cylinder 426 for driving the second side limit plate 425 to move horizontally. Since the bottle is in a semi-lying state on the second carrier 433, after the second clamping jaw assembly 423 clamps the bottle, the bottle may not completely return to the standing state even under the action of its own gravity. After the second clamping jaw assembly 423 clamps the bottle, the fourth cylinder 426 drives the second side limit plate 425 to press against one side of the bottle, and cooperates with the first side limit plate 424 to adjust the bottle to the standing state, and then stably places it on the unloading conveyor line 2 to complete the unloading.
