Description

Technical Field

[0001] This utility model relates to the field of labeling technology, and more specifically, to a label backing paper tearing structure. Background Technology

[0002] In the automated labeling process of water transfer printing labels, the existing labeling machines generally adopt a single suction nozzle structure for the bottom paper removal device, which is used to process two labels as a group. The working process is as follows: the mechanical gripping module first grabs the water transfer printing label that has been soaked in water to the bottom paper removal suction nozzle. After the suction nozzle adsorbs the bottom paper of the label, the gripping module generates friction through relative movement with the suction nozzle, so that the label and the bottom paper are separated. After the separation is completed, the suction nozzle discharges the bottom paper into the waste paper frame by back-blowing.

[0003] Existing technology suffers from unstable waste removal of the bottom paper. Because the waste is removed by using a suction nozzle backflushing method, the backflushing air pressure is easily affected by factors such as air source fluctuations and changes in pipeline resistance, resulting in unstable backflushing force. This will cause incomplete removal of the bottom paper, and the residual bottom paper may interfere with subsequent labeling operations. If the backflushing force is too large, it may also cause the bottom paper to splatter, affecting the cleanliness of the surrounding environment of the equipment.

[0004] Meanwhile, the separation process between the label and the backing paper is prone to failure because the labels are in pairs. The single suction nozzle structure can only provide suction support for the backing paper of one label, while the backing paper of the other label is unsupported during separation. This results in uneven stress on the backing paper of the two sets of labels when friction is generated during relative motion. The backing paper on the unsupported side is prone to tearing due to excessive local tension, and the separation interface is unstable. Some labels may not be able to completely separate from the backing paper, thereby increasing the scrap rate and affecting the continuity of production. Utility Model Content

[0006] The embodiments of this utility model are implemented as follows:

[0007] This utility model embodiment provides a label-tearing backing paper structure, which includes a label transfer component, a dual-station label peeling component, and a backing material channel;

[0008] The aforementioned dual-station label peeling assembly is rotatably mounted above the aforementioned bottom material channel, and the aforementioned label transfer assembly is movably located above the aforementioned dual-station label peeling assembly.

[0009] The label transfer assembly described above has a first fixed suction head and a second rotating suction head, and the first fixed suction head and the second rotating suction head are respectively connected to a cylinder.

[0010] The aforementioned dual-station label peeling assembly has a first suction head plate and a second suction head plate for suctioning and blowing the label backing paper.

[0011] In use, the first fixed suction head and the second rotating suction head of the label transfer assembly pick up the labels with backing paper after they have been soaked in water. The label transfer assembly places the labels with backing paper into the first suction head plate or the second suction head plate of the dual-station label peeling assembly. The label transfer assembly adopts a horizontal friction peeling method, and the label is separated from the backing paper by the lateral translational movement of the label transfer assembly, ensuring the stability and reliability of the peeling process. After peeling, the dual-station label peeling assembly rotates 180 degrees to facilitate blowing the peeled backing paper into the bottom material channel for centralized collection.

[0012] The label-tearing backing paper structure disclosed in this embodiment, having the aforementioned label transfer component, dual-station label peeling component, and backing material channel, facilitates the adsorption and lateral movement of the label by the first fixed suction head and the second rotating suction head of the label transfer component, peeling the label off the backing paper. This achieves efficient peeling and labeling, resulting in a label-tearing backing paper structure with the beneficial effects of thorough backing paper waste removal, low label scrap rate, low production cost, high labeling quality, ensuring production efficiency, and improving product qualification rate.

[0013] Optionally, the label transfer assembly has a rotatable telescopic rod, and the label transfer assembly is connected to a first robotic arm via the telescopic rod.

[0014] With this configuration, the first robotic arm can move the label transfer component to pick up the soaked label with backing paper, so as to place the soaked label with backing paper onto the first or second suction head plate of the dual-station label peeling component. The cooperation between the telescopic rod and the first robotic arm enables the label transfer component to be adjusted upwards and at an angle.

[0015] Optionally, the bottom of the first robotic arm is bolted to a first support frame for support, and the first support frame is bolted to the workstation.

[0016] With this configuration, the first support frame is used to support the first robotic arm, so that the first robotic arm has sufficient height to move the label transfer component, thereby facilitating the label transfer component to pick up the label with the backing paper. At the same time, it keeps the first robotic arm away from the ground to avoid damage.

[0017] Optionally, the bottom flange of the telescopic rod is connected to a horizontal plate, and the ends of the first fixed suction head and the second rotating suction head near the horizontal plate are fixed side by side on the side of the horizontal plate away from the telescopic rod.

[0018] With this configuration, the first fixed suction head and the second rotating suction head can be arranged side by side via the aforementioned horizontal plate, facilitating the simultaneous horizontal peeling of two labels, effectively reducing production costs and improving production efficiency.

[0019] Optionally: The first fixed suction head is connected to a fixed suction head seat at one end near the horizontal plate, and the fixed suction head seat is externally connected to a cylinder for driving the first fixed suction head to pick up the suction. The fixed suction head seat is fixed on the horizontal plate.

The rotating suction head seat is externally connected to a cylinder for driving the second rotating suction head to pick up food. The rotating suction head seat is fixed to the horizontal plate.

[0021] With this configuration, the fixed suction head holder provides the driving source for the first fixed suction head to pick up the label, making it easy for the cylinder to control the first fixed suction head through the fixed suction head holder. The rotating suction head holder enables the second rotating suction head to have four-way rotation adjustment function, which is used to adjust the suction head posture when mechanical interference occurs, ensuring obstacle avoidance and reliable label picking. At the same time, it is easy for the cylinder to control the second rotating suction head through the rotating suction head holder.

[0022] Optionally: One end of the dual-station label peeling assembly is provided with a servo motor, the servo motor has a rotating shaft, and the end of the rotating shaft near the dual-station label peeling assembly is fixed to one end of the dual-station label peeling assembly.

[0023] With this configuration, the dual-station label peeling assembly can be rotated 180 degrees by the rotating shaft of the servo motor, so that the first or second suction plate with the backing paper can be aligned with the bottom material channel. This facilitates the removal of the backing paper from the first or second suction plate and its feeding into the bottom material channel below. By adding a transfer mechanism, this dual-station panel can label two products simultaneously, significantly improving production capacity.

[0024] Optionally: the servo motor is connected to a support column, the support column is bolted to the workstation, and several reinforcing ribs are welded to the side of the support column.

[0025] With this configuration, the support column provides support for the dual-station label peeling assembly, allowing the dual-station label peeling assembly to be suspended above the bottom material channel. At the same time, the reinforcing ribs help to improve the strength of the support column, thereby making the suspension of the dual-station label peeling assembly more stable.

[0026] Optionally: An air valve body is provided between the first suction head plate and the second suction head plate of the dual-station label peeling assembly. The first suction head plate and the second suction head plate are respectively bolted to the two sides of the air valve body. The adsorption areas of the first suction head plate and the second suction head plate are provided with several small holes. The end of the air valve body away from the servo motor has a first air inlet and a second air inlet. The first air inlet is connected to the small hole of the first suction head plate, and the second air inlet is connected to the small hole of the second suction head plate.

[0027] With this configuration, after the label is peeled off, the first or second suction head plate continues to absorb the backing paper. Subsequently, the rotating shaft drives the dual-station label peeling assembly to rotate 180 degrees, so that the first or second suction head plate with the backing paper aligns with the bottom material channel. At this position, the control system blows air into the first or second air inlet of the air valve body, and the gas will be discharged from several pin holes on the first or second suction head plate, so as to detach the backing paper from the first or second suction head plate and send it into the bottom material channel below.

[0028] Optionally: The above-mentioned bottom material channel has a guide bucket.

[0029] With this configuration, the aforementioned feed hopper is used to receive and discharge the waste label backing paper blown off from the aforementioned dual-station label peeling assembly.

[0030] Optionally, a flared opening is welded to one end of the feed hopper near the dual-station label peeling assembly.

[0031] With this configuration, the aforementioned flared opening makes it easy for the material guide hopper to receive the waste label backing paper blown off by the dual-station label peeling component, preventing the waste label backing paper from falling outside the material channel and facilitating reliable collection of the backing paper.

[0043] Example

[0044] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This embodiment proposes a label-tearing backing paper structure, including a label transfer component 1, a dual-station label peeling component 2, and a backing material channel 3;

[0045] The dual-station label peeling assembly 2 is rotatably mounted above the bottom material channel 3, and the label transfer assembly 1 is movably located above the dual-station label peeling assembly 2.

[0046] The label transfer assembly 1 has a first fixed suction head 4 and a second rotating suction head 5, and the first fixed suction head 4 and the second rotating suction head 5 are respectively connected to cylinders (not shown in the figure).

[0047] The dual-station label peeling assembly 2 has a first suction head plate 6 and a second suction head plate 7 for suctioning and blowing the label backing paper.

[0048] In use, the first fixed suction head 4 and the second rotating suction head 5 of the label transfer component 1 pick up the labels with backing paper after they have been soaked in water. The label transfer component 1 places the labels with backing paper into the first suction head plate 6 or the second suction head plate 7 of the dual-station label peeling component 2. The label transfer component 1 adopts a horizontal friction peeling method. The label is separated from the backing paper by the lateral translation movement of the label transfer component 1, which ensures the stability and reliability of the peeling process. After peeling is completed, the dual-station label peeling component 2 rotates 180 degrees, which makes it easier to blow the peeled backing paper into the bottom material channel 3 for centralized collection.

[0049] The label-tearing backing paper structure disclosed in this embodiment is equipped with a label transfer component 1, a dual-station label peeling component 2, and a backing material channel 3. This facilitates the label to be picked up by the first fixed suction head 4 and the second rotating suction head 5 of the label transfer component 1 and moved laterally to peel the label off the backing paper. This achieves efficient peeling and labeling, resulting in a label-tearing backing paper structure with the beneficial effects of thorough backing paper waste removal, low label scrap rate, low production cost, high labeling quality, ensuring production efficiency, and improving product qualification rate.

[0050] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The label transfer assembly 1 has a rotatable telescopic rod 8. The label transfer assembly 1 is connected to a first robotic arm 9 via the telescopic rod 8. The first robotic arm 9 can move the label transfer assembly 1 to pick up the soaked label with backing paper, so as to place the soaked label with backing paper onto the first suction plate 6 or the second suction plate 7 of the dual-station label peeling assembly 2. The cooperation between the telescopic rod 8 and the first robotic arm 9 enables the label transfer assembly 1 to be adjusted upwards and at an angle.

[0051] The bottom of the first robotic arm 9 is bolted to a first support frame 10 for support. The first support frame 10 is bolted to the workstation and is used to support the first robotic arm 9, so that the first robotic arm 9 has enough height to move the label transfer component 1, thereby facilitating the label transfer component 1 to pick up the label with the backing paper. At the same time, it keeps the first robotic arm 9 away from the ground to avoid damage.

[0052] The bottom flange of the telescopic rod 8 is connected to a horizontal plate 11. The first fixed suction head 4 and the second rotating suction head 5 are fixed side by side on the side of the horizontal plate 11 away from the telescopic rod 8. The horizontal plate 11 can be used to arrange the first fixed suction head 4 and the second rotating suction head 5 side by side, which makes it convenient to peel off two labels horizontally at the same time, effectively reducing production costs and improving production efficiency.

[0053] The first fixed suction head 4 is connected to a fixed suction head seat 12 at one end near the horizontal plate 11. The fixed suction head seat 12 is externally connected to a cylinder (not shown in the figure) for driving the first fixed suction head 4 to pick up the label. The fixed suction head seat 12 is fixed on the horizontal plate 11. The second rotating suction head 5 is rotatably connected to a rotating suction head seat 13 at one end near the horizontal plate 11. The rotating suction head seat 13 is externally connected to a cylinder (not shown in the figure) for driving the second rotating suction head 5 to pick up the label. The rotating suction head seat 13 is fixed on the horizontal plate 11. The fixed suction head seat 12 provides the driving source for the first fixed suction head 4 to pick up the label, so that the cylinder can control the first fixed suction head 4 through the fixed suction head seat 12. The rotating suction head seat 13 enables the second rotating suction head 5 to have a four-way rotation adjustment function, which is used to adjust the suction head posture when mechanical interference occurs, to ensure obstacle avoidance and reliable label picking. At the same time, it is convenient for the cylinder to control the second rotating suction head 5 through the rotating suction head seat 13.

[0054] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The dual-station label peeling assembly 2 is equipped with a servo motor 14 at one end. The servo motor 14 has a rotating shaft 15. The end of the rotating shaft 15 near the dual-station label peeling assembly 2 is fixed to one end of the dual-station label peeling assembly 2. The dual-station label peeling assembly 2 is driven to rotate 180 degrees by the rotating shaft 15 of the servo motor 14, so that the first suction plate 6 or the second suction plate 7 with the backing paper can be aligned with the bottom material channel 3. This facilitates the removal of the backing paper from the first suction plate 6 or the second suction plate 7 and its feeding into the bottom material channel 3 below. With the addition of a set of transfer mechanisms, this dual-station assembly can label two products at the same time, significantly improving production capacity.

[0055] The servo motor 14 is connected to a support column 16, which is bolted to the workstation. Several reinforcing ribs 17 are welded to the side of the support column 16. The support column 16 provides support for the dual-station label peeling assembly 2, making it easier for the dual-station label peeling assembly 2 to be suspended above the bottom material channel 3. At the same time, the several reinforcing ribs 17 help to improve the strength of the support column 16, thereby making the dual-station label peeling assembly 2 more stable.

[0056] A valve body 18 is provided between the first suction head plate 6 and the second suction head plate 7 of the dual-station label peeling assembly 2. The first suction head plate 6 and the second suction head plate 7 are respectively bolted to the two sides of the valve body 18. The adsorption areas of the first suction head plate 6 and the second suction head plate 7 are provided with several small holes 19. The end of the valve body 18 away from the servo motor 14 has a first air inlet 20 and a second air inlet 21. The first air inlet 20 is connected to the small hole 19 of the first suction head plate 6, and the second air inlet 21 is connected to the small hole 19 of the second suction head plate 7. When the label is peeled off... After removal, the first suction plate 6 or the second suction plate 7 continues to absorb the backing paper. Subsequently, the rotating shaft 15 drives the dual-station label peeling assembly 2 to rotate 180 degrees, so that the first suction plate 6 or the second suction plate 7 with the backing paper corresponds to the bottom material channel 3. At this position, the control system blows air into the first air inlet 20 or the second air inlet 21 of the air valve body 18. The gas will be discharged from several pin holes 19 on the first suction plate 6 or the second suction plate 7, so as to remove the backing paper from the first suction plate 6 or the second suction plate 7 and send it into the bottom material channel 3 below.

[0057] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The bottom material channel 3 has a guide bucket 22, which is used to receive and discharge the waste label backing paper blown off from the dual-station label peeling assembly 2.

[0058] The guide hopper 22 has a flared mouth 23 welded to one end near the dual-station label peeling component 2. The flared mouth 23 makes it easy for the guide hopper 22 to receive the waste label backing paper blown off by the dual-station label peeling component 2, preventing the waste label backing paper from falling to the outside of the material channel 3, and facilitating the reliable collection of the backing paper.

[0059] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the tag transfer component 1 adopts the form of a first robotic arm 9 + a fixture. The fixture is equipped with a first fixed suction head 4 and a second rotating suction head 5 (vacuum). The second rotating suction head 5 has four-way adjustment function (up, down, left, and right) to adjust the suction head posture when mechanical interference occurs, so as to ensure obstacle avoidance and reliable tag picking.

[0060] In this embodiment, both the first fixed suction head 4 and the second rotating suction head 5 can be driven by a cylinder to extend and retract to pick up the label, and the second rotating suction head 5 can be driven by a cylinder to pick up the label. A label with a backing paper has two labels. When one label is damaged, the corresponding first fixed suction head 4 or second rotating suction head 5 retracts and does not pick up the label. When both labels are damaged, both the first fixed suction head 4 and the second rotating suction head 5 retract and do not pick up the two labels.

[0061] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the dual-station label peeling assembly 2 adopts a high-efficiency double-sided design. For example, the first suction plate 6 is responsible for adsorbing and fixing the label backing paper during operation, while the second suction plate 7 is responsible for receiving and transferring the waste backing paper after peeling. During operation, the first suction plate 6 of the dual-station label peeling assembly 2 adsorbs the backing paper, and the label transfer assembly 1 adsorbs the label. The label is separated from the backing paper by lateral relative movement (friction). Compared with the traditional vertical tearing, this horizontal peeling method can effectively reduce the risk of label deformation, tearing or displacement, thereby greatly reducing the generation of waste labels due to poor peeling.

[0062] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The workflow of the label-tearing backing paper structure in this embodiment is as follows:

[0063] Step 1: Peeling stage. The label (along with the backing paper) is placed on the surface of the first suction head plate 6. At this time, the first suction head plate 6 adsorbs and fixes the label backing paper. At the same time, the first fixing suction head 4 and the second rotating suction head 5 of the label transfer assembly 1 adsorb the label and move laterally to peel the label off the backing paper.

[0064] Step 2: Backing paper processing stage. After the label is peeled off, the first suction head plate 6 continues to absorb the backing paper. Subsequently, the rotating shaft 15 drives the dual-station label peeling assembly 2 to rotate 180 degrees, so that the first suction head plate 6 with the backing paper corresponds to the backing material channel 3. At this position, the system blows air onto the backing paper through the first air inlet 20 or the second air inlet 21, detaching the backing paper from the first suction head plate 6 and sending it into the lower backing material channel 3. The adjustable second rotating suction head 5 avoids interference risks. Combined with the rotation design and air blowing unloading mechanism of the dual-station label peeling assembly 2, the automated and efficient peeling of the label and the reliable collection of the backing paper are achieved.

[0065] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The specific working principle of the label peeling backing paper structure in this embodiment is as follows: First, when the label transfer component 1 transfers the label with the backing paper to the first suction plate 6 of the dual-station label peeling component 2, the label is placed on the first suction plate 6. The first suction plate 6 adsorbs the backing paper through several small holes 19. After the label is peeled off, the first suction plate 6 remains in the state of adsorbing the backing paper. The rotating shaft 15 drives the whole to rotate 180 degrees. After the rotation, the first suction plate 6 is located at the bottom. The system blows the backing paper to detach it and it falls into the bottom material channel 3. When the first suction plate 6 is in the above-mentioned rotation (unloading stage), the second suction plate 7 has rotated to the upward working position. At this time, another label transfer mechanism (or another pickup unit of the same component) can place the new label on the second suction head plate 7 and immediately carry out the next round of peeling operation. In this way, the peeling operation and the unloading of the backing paper and the preparation of new material are carried out at the same time, which significantly reduces the equipment waiting time and greatly improves the overall efficiency. Secondly, the dual-station label peeling component 2 adsorbs and fixes the label backing paper. Then, the label transfer component 1 adsorbs the label through the first fixed suction head 4 and the second rotating suction head 5 and performs a lateral translation movement (usually moving towards the target carrier). During this translation process, the label is horizontally peeled (friction peeling) off its backing paper.

[0066] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6In this embodiment, a second robotic arm 24 is also provided, with a label transfer component 1 attached to it. During alternating operation: the first robotic arm 9 picks up a label from the immersion tank 25 and places it on the second suction plate 7 of the preparation station of the dual-station label peeling component 2; the second robotic arm 24 then picks up the label from the first suction plate 6 and performs the labeling operation after peeling. During parallel operation: under equipment-permitted conditions, the first robotic arm 9 and the second robotic arm 24 achieve near-synchronous label picking, peeling, and labeling. By flexibly configuring the number of robotic arms, the potential of double-sided labels can be effectively matched, significantly increasing the labeling output per unit time.

[0067] See Figure 6 After the label is soaked in the immersion tank 25, either the first robotic arm 9 or the second robotic arm 24 can pick up the label through the label transfer component 1 and place it on the dual-station label peeling component 2. The first robotic arm 9 or the second robotic arm 24 moves laterally (usually moving towards the target carrier). During this translation process, the label is horizontally peeled off its backing paper. The label without backing paper on the first robotic arm 9 or the second robotic arm 24 is affixed to the labeling area of ​​the bottle 26.

[0068] In summary, the label is peeled off from the backing paper using a horizontal friction peeling method. The label transfer component 1 achieves separation of the label from the backing paper through lateral translation, ensuring the stability and reliability of the peeling process. The first suction plate 6 and the second suction plate 7 work together with a 180-degree rotation design to enable simultaneous peeling, backing paper unloading, and new material preparation operations, significantly reducing equipment waiting time and greatly improving overall efficiency. This achieves efficient label tearing, reduces waste generated during the label tearing process, and facilitates the recycling of label backing paper. This patent has good promotional significance and practical application value for label tearing and labeling equipment.
