Description

Technical Field

[0001] The invention relates to the technical field of liquid addition processing of an absorption bottle, and in particular to a liquid addition self-service labeling device and a labeling system for an absorption bottle. Background Art

[0002] An atmospheric absorption bottle is a glass container that uses a solution absorption method to collect pollutants in the atmosphere. Compared with ordinary glass containers, it has a complex structure. When in use, it is necessary to fill the bottle with an absorption liquid of a specific composition and ensure that the atmospheric absorption bottle has a qualified bottle resistance. After the absorption liquid is added to the absorption bottle, a label needs to be attached to the bottle body of the absorption bottle for identification. The current labeling device is difficult to attach the label to the round bottle body of the absorption bottle, and the label needs to be attached manually, which is difficult to meet the needs of automation. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a self-service labeling device and a labeling system for liquid filling of an absorption bottle, which has the advantage of being able to realize automatic labeling on the body of the absorption bottle.

[0004] To achieve the above object, the technical solution of the present invention is as follows:

[0005] A self-service labeling device for adding liquid to an absorption bottle, comprising:

[0006] A mounting bracket, wherein a printing device for printing a label is provided on the mounting bracket;

[0007] a label pressing component carried by the mounting bracket and used for pressing the label belt to keep the label in a vertical state; and

[0008] The labeling mechanism is carried by the mounting bracket and is used to take out the label from the label belt and attach it to the body of the absorption bottle. The labeling mechanism includes: a movable label taking seat, an elastic labeling component arranged at the front end of the movable label taking seat, a label taking component carried by the movable label taking seat and used to press against the elastic labeling component to adsorb the label, a first transfer driving mechanism used to drive the movable label taking seat to reciprocate to take out the label from the label belt or attach the label to the body of the absorption bottle, and a second transfer driving mechanism used to drive the movable label taking seat to move from the printing device to the labeling station, the elastic labeling component is provided with a plurality of first adsorption holes, the label taking component is provided with second adsorption holes corresponding to the first adsorption holes, the second adsorption holes are connected to the negative pressure adsorption device, and the elastic labeling mechanism can undergo elastic deformation to cover the body of the absorption bottle.

[0009] To implement the above technical solution, when labeling, the printing device prints the labels one by one, and each time a label is printed, the label pressing component presses the label once, at this time, the second transfer drive mechanism drives the first transfer drive mechanism to move until the elastic labeling component is aligned with the label belt, and then the first transfer drive mechanism drives the movable label picking seat to move forward until the elastic labeling component is fitted with the label, and then the elastic labeling component is pressed against the label by the label picking component, and negative pressure is generated by the negative pressure adsorption device. At this time, since the first adsorption hole corresponds to the second adsorption hole, the label can be adsorbed on the front end of the elastic labeling component, and then the second transfer drive mechanism drives the movable label picking seat to move forward until the elastic labeling component is aligned with the label belt, and then the movable label picking seat .... The movable assembly drives the movable label picking seat to move backward, removes the label from the label belt, and then releases the label pressing assembly to print the next label; the second transfer driving mechanism then drives the movable label picking seat to move to the labeling station corresponding to the absorption bottle, and then the first transfer driving assembly drives the elastic labeling assembly again to make the label adhere to the absorption bottle. When the label is tightly attached to the absorption bottle, the label picking assembly retreats and the first transfer driving assembly continues to drive the movable label picking seat forward. At this time, the elastic labeling assembly undergoes elastic deformation and gradually covers the body of the absorption bottle, thereby completely attaching the label to the absorption bottle, realizing automatic labeling and meeting the needs of automatic detection.

[0010] As a preferred solution of the present invention, the elastic labeling assembly includes: an elastic support plate fixed to both sides of the front end of the movable label picking seat, and an elastic adsorption plate fixed to the front end of the elastic support plate, and the first adsorption hole is arranged in the middle of the elastic adsorption plate.

[0011] As a preferred solution of the present invention, the label picking assembly includes: a label picking cylinder fixed to the movable label picking seat, and a label picking pressure head fixed to the piston rod of the label picking cylinder, and the second adsorption hole is arranged in the middle of the label picking pressure head.

[0012] To implement the above technical solution, when removing the label, the label removing pressure head is driven by the label removing cylinder to extend to fit with the elastic adsorption plate. When the elastic adsorption plate and the label removing pressure head are pressed against the label, the label can be sucked out by the negative pressure generated by the negative pressure adsorption device. When labeling, the label removing pressure head and the elastic adsorption plate are first kept in a fit state. After the label is attached to the absorption bottle, the label removing cylinder drives the label removing pressure head to retract and separate from the elastic adsorption plate. Then the first transfer drive mechanism continues to drive the elastic adsorption plate forward. At this time, the elastic support plate and the elastic adsorption plate gradually undergo elastic deformation, and the elastic adsorption plate gradually wraps around the adsorption bottle, thereby attaching the label to the adsorption bottle.

[0013] As a preferred solution of the present invention, the front end surface of the label removing pressure head is arc-shaped, and the middle part of the elastic adsorption plate is arc-shaped to match the front end surface of the label removing pressure head.

[0014] To implement the above technical solution, when the label removal pressure head and the elastic adsorption plate press the label, they undergo elastic deformation to form a plane. After the label is adsorbed, during the process of the label removal pressure head and the elastic adsorption plate retreating, the label removal pressure head and the elastic adsorption plate gradually undergo elastic reset from both sides to the center, so that the label can be peeled off from the edge, making it easier to detach the label from the label tape.

[0015] As a preferred solution of the present invention, the label pressing assembly includes: a label pressing plate connected to the printing outlet of the printing device and in contact with the label tape, a label pressing cylinder fixed to the mounting bracket, and a piston rod fixed to the label pressing cylinder for pressing the label tape against the pressure claw of the label pressing plate.

[0016] To implement the above technical solution, the label tape can be pressed against the label plate by driving the label pressing claw through the label pressing cylinder, so that the label tape can be pressed for label removal.

[0017] As a preferred solution of the present invention, the first transfer drive mechanism and the second transfer drive mechanism are selected from the following structures, either alone or in combination: a servo electric cylinder, a servo screw mechanism or a belt drive mechanism.

[0018] On the other hand, an embodiment of the present invention further provides a self-service labeling system for adding liquid to an absorption bottle, comprising:

[0019] A working machine, wherein a supporting plate is provided on the working machine, and a servo motor for driving the supporting plate to rotate is also provided on the working machine;

[0020] A plurality of spacer rings are arranged on the supporting plate, a first clamping mechanism and a second clamping mechanism for clamping the absorbent bottle to be labeled; and,

[0021] In the labeling device as described in any of the above technical solutions, the first clamping mechanism and the second clamping mechanism can be rotated to positions corresponding to the elastic labeling assembly.

[0022] To implement the above technical solution, when working, the absorption bottle is clamped on the first clamping mechanism and the second clamping mechanism. Since the commonly used absorption bottles have two structures, it is necessary to adopt the first clamping mechanism and the second clamping mechanism to clamp them respectively. Then, the servo motor drives the supporting plate to rotate, and the absorption bottle is rotated to the labeling station in turn, which corresponds to the elastic labeling component. Then, the labeling component can perform automatic labeling operation to improve the labeling efficiency.

[0023] As a preferred solution of the present invention, the first clamping mechanism includes: a first clamping frame fixed to the supporting carrier, a first clamping seat rotatably assembled on the first clamping frame, a supporting insert carried by the first clamping seat, a first air clamp carried by the first clamping seat for clamping the liquid adding bottle, and a first angle adjustment cylinder hinged at one end to the supporting carrier and at the other end to the first clamping seat.

[0024] To implement the above technical solution, the absorption bottle is inserted into the supporting insert for pre-fixation, and then the absorption bottle is clamped by the first air clamp. The absorption bottle is adjusted to a vertical state when labeling through the first angle adjustment cylinder, and the absorption bottle is adjusted to a corresponding angle when performing other operations, thereby meeting different operational requirements.

[0025] As a preferred solution of the present invention, the second clamping mechanism includes: a second clamping frame fixed to the supporting plate, a second clamping seat rotatably assembled on the second clamping frame, a second air clamp carried by the second clamping seat for clamping the liquid inlet of the absorption bottle, a positioning component for locating the position of the liquid inlet of the absorption bottle, and a second angle adjustment cylinder hinged at one end to the supporting plate and at the other end to the second clamping seat.

[0026] As a preferred solution of the present invention, the positioning assembly includes: a positioning cylinder fixed to the second clamping seat, a movable guide rail arranged on the clamping jaws of the second air clamp, and a positioning plate fixed to the positioning cylinder and movably connected to the movable guide rail; the second clamping seat is also provided with an auxiliary air clamp for clamping the absorption bottle.

[0027] To implement the above technical solution, the liquid inlet of the absorption bottle is brought into contact with the positioning plate to position the absorption bottle at a corresponding angle, and then the liquid inlet of the absorption bottle is clamped by the second air clamp. When performing other operations, such as liquid adding operations, the positioning plate can be driven to move by the positioning cylinder to expose the liquid inlet of the absorption bottle, and the absorption bottle can be adjusted to a vertical state during labeling through the second angle adjustment cylinder, and adjusted to a corresponding angle during other operations, thereby meeting different operational requirements. At the same time, the absorption bottle can be clamped by the auxiliary air clamp when the absorption bottle rotates, thereby making the rotation of the absorption bottle more stable and reducing damage to the liquid inlet of the absorption bottle.

[0028] In summary, the present invention has the following beneficial effects:

[0029] The embodiment of the present invention provides a self-service labeling device and a labeling system for adding liquid to an absorption bottle. When labeling, a printing device prints the labels one by one. Each time a label is printed, the label is pressed once by a label pressing component. At this time, the first transfer driving mechanism drives the first transfer driving mechanism to move to the elastic labeling component to align with the label belt. Then, the first transfer driving mechanism drives the movable label picking seat to move forward to the elastic labeling component to fit the label. Then, the label picking component presses the elastic labeling component to the label, and a negative pressure is generated by a negative pressure adsorption device. At this time, since the first adsorption hole corresponds to the second adsorption hole, the label can be adsorbed on the elastic labeling component. At the front end, the second transfer driving component then drives the active label picking seat to move backward, removes the label from the label belt, and then releases the label pressing component to print the next label; the second transfer driving mechanism then drives the active label picking seat to move to the labeling station corresponding to the absorption bottle, and then the first transfer driving component drives the elastic labeling component again to make the label adhere to the absorption bottle. When the label is tightly attached to the absorption bottle, the label picking component retreats and the first transfer driving component continues to drive the active label picking seat forward. At this time, the elastic labeling component undergoes elastic deformation and gradually covers the body of the absorption bottle, thereby completely attaching the label to the absorption bottle, realizing automatic labeling and meeting the needs of automatic detection.

[0045] The liquid inlet of the absorption bottle is pressed against the positioning plate 643 to position the absorption bottle at a corresponding angle, and then the liquid inlet of the absorption bottle is clamped by the second air clamp 63.

At the same time, the absorption bottle can be clamped by the auxiliary air clamp 66 when the absorption bottle rotates, so that the rotation of the absorption bottle is more stable and damage to the liquid inlet of the absorption bottle can be reduced.

[0046] The labeling device includes: a mounting bracket 1, on which a printing device 11 for printing labels is provided; a label pressing component 2 carried by the mounting bracket 1 and used to press the label belt so that the label is in a vertical state; and a labeling mechanism 3 carried by the mounting bracket 1 and used to take the label out of the label belt and attach it to the body of the absorbent bottle.

[0047] The labeling mechanism 3 includes: a movable labeling seat 31, an elastic labeling component 32 arranged at the front end of the movable labeling seat 31, a labeling component 33 carried by the movable labeling seat 31 and used to press against the elastic labeling component 32 to adsorb the label, a first transfer driving mechanism 34 used to drive the movable labeling seat 31 to move back and forth to remove the label from the label belt or attach the label to the body of the absorption bottle, and a second transfer driving mechanism 35 used to drive the movable labeling seat 31 to move from the printing device 11 to the labeling station. The elastic labeling component 32 is provided with a plurality of first adsorption holes 323, and the labeling component 33 is provided with second adsorption holes 333 corresponding to the first adsorption holes 323. The second adsorption holes 333 are connected to the negative pressure adsorption device, and the elastic labeling mechanism 3 can undergo elastic deformation to cover the body of the absorption bottle.

[0048] The elastic labeling component 32 includes: an elastic support plate 321 fixed to both sides of the front end of the movable label picking seat 31, and an elastic adsorption plate 322 fixed to the front end of the elastic support plate 321, the first adsorption hole 323 is arranged in the middle of the elastic adsorption plate 322, and the elastic support plate 321 and the elastic adsorption plate 322 can be made of elastic metal material; the label picking component 33 includes: a label picking cylinder 331 fixed to the movable label picking seat 31, and a label picking pressure head 332 fixed to the piston rod of the label picking cylinder 331, the label picking pressure head 332 is made of rubber material, the second adsorption hole 333 is arranged in the middle of the label picking pressure head 332, and a plurality of adsorption grooves can be further arranged in the front section of the label picking pressure head 332, the second adsorption hole 333 is located in the adsorption groove, so that the adsorption force can be increased through the adsorption groove.

[0049] When removing the label, the label removing pressure head 332 is driven by the label removing cylinder 331 to extend to fit with the elastic adsorption plate 322. When the elastic adsorption plate 322 and the label removing pressure head 332 are pressed against the label, the label can be sucked out by the negative pressure generated by the negative pressure adsorption device; when labeling, the label removing pressure head 332 is first kept in a fit state with the elastic adsorption plate 322. After the label is attached to the absorption bottle, the label removing cylinder 331 drives the label removing pressure head 332 to retract and separate from the elastic adsorption plate 322. Then the first transfer drive mechanism 34 continues to drive the elastic adsorption plate 322 to move forward. At this time, the elastic support plate 321 and the elastic adsorption plate 322 gradually undergo elastic deformation, and the elastic adsorption plate 322 gradually wraps around the adsorption bottle, thereby attaching the label to the adsorption bottle.

[0050] In this embodiment, the front end surface of the label removal pressure head 332 is arc-shaped, and the middle part of the elastic adsorption plate 322 is arc-shaped to match the front end surface of the label removal pressure head 332. When the label removal pressure head 332 and the elastic adsorption plate 322 press the label, the label removal pressure head 332 and the elastic adsorption plate 322 are elastically deformed to form a plane. After the label is adsorbed, in the process of retreating the label removal pressure head 332 and the elastic adsorption plate 322, the label removal pressure head 332 and the elastic adsorption plate 322 gradually elastically reset from both sides to the center, so that the label can be peeled off from the edge, so that the label can be more conveniently detached from the label belt.

[0051] The label pressing component 2 includes: a label pressing plate 21 connected to the printing outlet of the printing device 11 and fitted with the label tape, a label pressing cylinder 22 fixed to the mounting bracket 1, and a piston rod fixed to the label pressing cylinder 22 for pressing the label tape against a pressing claw 23 of the label pressing plate 21. The pressing claw 23 is U-shaped and arranged horizontally, and the label pressing plate 21 is located between the pressing claws 23. The label pressing cylinder 22 drives the pressing claw 23 to press the label tape against the label pressing plate 21, so that the label tape can be pressed for label removal.

[0052] The first transfer drive mechanism 34 and the second transfer drive mechanism 35 are selected from the following structures alone or in combination: a servo electric cylinder, a servo screw mechanism or a belt drive mechanism. In this embodiment, the first transfer drive mechanism 34 and the second transfer drive mechanism 35 are both servo screw mechanisms.

[0053] During operation, the absorption bottle is clamped on the first clamping mechanism 5 and the second clamping mechanism 6. Since the commonly used absorption bottles have two structures, the first clamping mechanism 5 and the second clamping mechanism 6 are required to be clamped respectively. Then, the servo motor drives the supporting plate 41 to rotate, and the absorption bottle is rotated to the labeling station in turn, corresponding to the elastic labeling component 32. Then, the labeling component can perform automatic labeling operation to improve the labeling efficiency.

[0054] During labeling, the printing device 11 prints the labels one by one. Each time a label is printed, the label pressing component 2 presses the label once. At this time, the second transfer driving mechanism 35 drives the first transfer driving mechanism 34 to move to the elastic labeling component 32 to align with the label belt. Then, the first transfer driving mechanism 34 drives the movable label picking seat 31 to move forward to the elastic labeling component 32 to fit the label. Then, the label picking component 33 presses the elastic labeling component 32 to the label, and negative pressure is generated by the negative pressure adsorption device. At this time, since the first adsorption hole 323 corresponds to the second adsorption hole 333, the label can be adsorbed on the front end of the elastic labeling component 32. Then, the second transfer driving mechanism 35 drives the first transfer driving mechanism 34 to move to the elastic labeling component 32 to align with the label belt. The transport driving assembly drives the movable label picking seat 31 to move backward, removes the label from the label belt, and then releases the label pressing assembly 2 to print the next label; the second transport driving mechanism 35 then drives the movable label picking seat 31 to move to the labeling station corresponding to the absorption bottle, and then the first transport driving assembly drives the elastic labeling assembly 32 again to make the label adhere to the absorption bottle. When the label is tightly attached to the absorption bottle, the label picking assembly 33 retreats and the first transport driving assembly continues to drive the movable label picking seat 31 to move forward. At this time, the elastic labeling assembly 32 undergoes elastic deformation and gradually covers the body of the absorption bottle, thereby completely attaching the label to the absorption bottle, realizing automatic labeling and meeting the needs of automatic detection.
