Description

Technical Field

[0001] This utility model relates to the technical field of sanitary material production equipment, specifically to an online non-stop roll material labeling device and a roll material production line. Background Technology

[0002] In the field of hygiene materials, especially for deep-processed products such as diapers, the surface material is produced using specific roll-shaped materials, which are supplied by upstream manufacturers. During production, due to the characteristics of roll-shaped materials, it is difficult to control the real-time roll diameter data during the unwinding process, resulting in significant deviations. This can lead to the following two situations: (1) a large amount of leftover material, resulting in waste; (2) the entire roll is unwound, causing the production line to stop due to the unwinding of the roll.

[0003] Since it is difficult for equipment computing power and human intervention to accurately identify the reasonable roll diameter data of the final used roll material, one proposed solution is to attach colored or metallic adhesive to the core of the roll material. Visual recognition or metal sensing can accurately identify the state of the tail material when it is about to end, which helps to achieve continuous production without stopping the machine to receive materials.

[0004] For roll materials that require a consistent inner looseness and outer tightness during production, when an identification tag needs to be affixed to the core, the machine needs to be started to produce a few meters first, and then stopped for affixing. However, frequent stops severely impact production efficiency. Secondly, for materials with high requirements for bulkiness, frequent starts and stops during winding can cause abnormalities in the roll material, such as collapse, chrysanthemum-like core formation, and uneven end faces, affecting usability and quality. Furthermore, for deeply processed products, specific bulge and perforation shapes are formed through die pressing at a certain melting temperature. When the machine stops, a portion of material will inevitably remain in the die roller's pressed state for an extended period, leading to problems such as melting, hardening, and breakage, seriously affecting product quality. Affixing identification tags (such as tape) after stopping and then restarting can cause tension changes, affecting product width and feel, and the ultrasonic waves will continue to operate at the stopped point, causing the product to harden and posing a risk of puncture.

[0043] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0044] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity and not intended to limit the scope of implementation. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0045] In one embodiment, this application proposes an online non-stop roll material labeling device, such as... Figure 1 , 2 As shown in Figures 3 and 4, the system includes a base 101, a drive mechanism 102, a marker adsorption mechanism 103, a toothed plate 206, a fixed base 104, a locking pin 203, a mounting base 201, and a connecting shaft 105. The base 101 and the fixed base 104 are rotatably connected. Specifically, the connecting shaft 105 is fixedly connected to the base 101, and the connecting shaft 105 is connected to the fixed base 104 via a bearing. In this case, as... Figure 6 As shown, the base 101 can rotate relative to the fixed base 104, and the axis of rotation of the base 101 is the axis of the connecting shaft 105.

[0046] The drive mechanism 102 is connected to the base 101. It should be noted that the drive mechanism 102 can be directly mounted on the base 101 or indirectly mounted on the base 101 through other components.

[0047] The marker adsorption mechanism 103 is connected to the drive mechanism 102. The drive mechanism 102 can drive the marker adsorption mechanism 103 to move linearly. Specifically, the drive mechanism 102 can drive the marker adsorption mechanism 103 to move closer to the sanitary material 402 and to move further away from the sanitary material 402.

[0048] For the drive mechanism 102, a cylinder can be selected, or other existing mechanisms capable of driving the marker adsorption mechanism 103 to perform reciprocating linear motion can be selected. These are relatively mature technologies and will not be elaborated or limited here. Preferably, the drive mechanism 102 shown in the accompanying drawings of this application is a cylinder. The cylinder body is mounted on the base 101, and the piston rod end of the cylinder is connected to the marker adsorption mechanism 103.

[0049] The label adsorption mechanism 103 functions to adsorb the identification material affixed to the sanitary material 402. It should be noted that the label adsorption mechanism 103 is not limited to adsorbing labels; it can also adsorb colored or metallic adhesive materials. The label 401 can be adhesive tape, such as… Figure 5 As shown, the adhesive surface of the marker 401 is away from the marker adsorption mechanism 103. The marker adsorption mechanism 103 is driven by the driving mechanism 102 to move toward the sanitary material 402. After the adhesive surface of the marker 401 contacts the sanitary material 402, the marker 401 can be pasted on the sanitary material 402.

[0050] Preferably, when the adhesive surface of the label 401 contacts the sanitary material 402, the driving mechanism 102 can further drive the label adsorption mechanism 103 to move a certain distance toward the sanitary material 402, thereby pressing against the label 401 and ensuring that the label 401 is firmly adhered to the sanitary material 402. When the label 401 is completely adhered to the sanitary material 402, the driving mechanism 102 can drive the label adsorption mechanism 103 to move away from the sanitary material 402.

[0051] The chainring 206 is fixedly connected to the base 104, meaning that when the base 101 rotates, the chainring 206 will not rotate with the base 101. The fixed connection between the chainring 206 and the base 104 can be a bolt connection, welding, or integral molding, etc.

[0052] The crankset 206 has an arc-shaped limiting groove 206-1 and a fixing groove 206-2, and one end of the locking pin 203 is rotatably connected to the base 101. It should be noted that one end of the locking pin 203 can be directly rotatably connected to the base 101, or a mounting base 201 can be installed on the base 101, and then one end of the locking pin 203 can be rotatably connected to the mounting base 201, i.e., one end of the locking pin 203 is indirectly connected to the base 101. Figure 2 As shown, one end of the locking pin 203 is rotatably connected to the base 101. The rotation axis of the locking pin 203 is perpendicular to the rotation axis of the base 101. The locking pin 203 can be moved so that the locking pin 203 rotates clockwise or counterclockwise around the center point with one end as the center point.

[0053] like Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown, when the locking pin 203 is rotated so that its other end is inserted into the arc-shaped limiting groove 206-1, the base 101 can rotate within the arc range of the arc-shaped limiting groove 206-1. When the other end of the locking pin 203 is inserted into the fixed locking groove 206-2, the base 101 can be restricted from rotating, that is, the base 101 cannot rotate relative to the fixed base 104 at this time.

[0054] Before affixing the label 401 to the sanitary material 402, first move the locking pin 203 to disengage it from the arc-shaped limiting groove 206-1. Then rotate the base 101 so that the adsorption surface of the label adsorption mechanism 103 faces the worker. The worker then places the label 401 on the adsorption surface of the label adsorption mechanism 103. During the placement of the label 401, the other end of the locking pin 203 can be inserted into the fixing slot 206-2, such as... Figure 7 As shown, the base 101 is fixed at this time and cannot rotate. The marker adsorption mechanism 103 is also fixed, which makes it easier for staff to place the marker 401 on the adsorption surface of the marker adsorption mechanism 103.

[0055] Then, move the pin 203 so that it leaves the fixed slot 206-2, rotate the base 101 so that the adhesive surface of the label 401 adsorbed on the label adsorption mechanism 103 faces the sanitary material 402, and at the same time insert the other end of the pin 203 into the arc-shaped limiting groove 206-1.

[0056] The label adsorption mechanism 103 is driven by the driving mechanism 102 to move towards the sanitary material 402. Once the adhesive surface of the label 401 contacts the sanitary material 402, the label 401 can be adhered to the sanitary material 402. For example... Figure 9As shown, since the base 101 and the label adsorption mechanism 103 can rotate, when the sanitary material 402 is rolled up, the moving sanitary material 402 can drive the label adsorption mechanism 103 and the base 101 to rotate, and the label 401 can be attached to the moving sanitary material 402, that is, the label 401 can be attached to the rolled sanitary material 402 without stopping the machine.

[0057] Once the labeling is complete, the label adsorption mechanism 103 removes the label 401, at which point the label 401 is fully adhered to the sanitary material 402. Then, the drive mechanism 102 drives the label adsorption mechanism 103 to move away from the sanitary material 402, and the base 101 rotates in the opposite direction to return to its original position, ready for the next application of the label 401.

[0058] In this embodiment, the locking pin 203 and the toothed plate 206 serve as guides when the base 101 rotates. When the marker 401 is placed on the adsorption surface of the marker adsorption mechanism 103, they also restrict the rotation of the base 101. The above functions can be achieved by operating only one locking pin 203, making it convenient to use.

[0059] Since the other end of the locking pin 203 can only move within the arc range of the arc-shaped limiting groove 206-1, the rotation angle of the base 101 is limited, and the base 101 can only rotate within the set arc range, thus limiting the rotation amplitude of the base 101. Specifically, limiting the rotation of the base 101 within the set range ensures that when the label 401 is attached, the adsorption surface of the label adsorption mechanism 103 is always in contact with the sanitary material, which is beneficial for the label 401 to be attached to the sanitary material 402.

[0060] If the rotation angle of the base 101 is unrestricted, the sanitary material 402 will cause the label adsorption mechanism 103 to rotate when it is rolled up. When the linear velocity of the label adsorption mechanism 103 is large, the label adsorption mechanism 103 will rotate away from the sanitary material 402 to a height where it cannot adhere to the sanitary material 402. Then, under the action of gravity, the label adsorption mechanism 103 will rotate towards the sanitary material 402, eventually colliding with the sanitary material 402 and causing damage to the sanitary material 402.

[0061] In addition, since the base 101 can only rotate within a set arc range, it can be ensured that only the position of the marker adsorption mechanism 103 adsorbing the marker 401 is in contact with the sanitary material 402. That is, the position of the sanitary material 402 that is squeezed by the marker adsorption mechanism 103 will be covered by the marker 401, while the area of ​​the sanitary material 402 that is not covered by the marker 401 will not be squeezed by the marker adsorption mechanism 103, thereby avoiding damage to the bulges and other structures provided on the sanitary material 402.

[0062] As an optional implementation, the axis of the crankset 206 coincides with the rotation axis of the base 101. In this case, the central angle of the arc-shaped limiting groove 206-1 provided on the crankset 206 is the range of rotation angles of the base 101. Preferably, the central angle of the arc-shaped limiting groove 206-1 is 10° to 30°, for example, 10°, 13°, 15°, 22°, or 30°.

[0063] The fixed slot 206-2 can be provided at least one, for example, two, three or four, etc. Preferably, the included angle between the fixed slot 206-2 and the arc-shaped limiting groove 206-1 is 100° to 160°, for example, 100°, 110°, 115°, 130°, 142°, 160°, etc. When the base 101 rotates to the position where the locking pin 203 corresponds to the fixed slot 206-2, the end of the locking pin 203 can be inserted into the fixed slot 206-2. Since the size of the fixed slot 206-2 is approximately the same as the end size of the locking pin 203, the locking pin 203 cannot move within the fixed slot 206-2. At this time, the base 101 cannot rotate and is fixed. At this time, the marker adsorption mechanism 103 is fixed, which makes it convenient to place the marker 401 on the adsorption surface of the marker adsorption mechanism 103.

[0064] In addition, since the included angle between the fixed card slot 206-2 and the arc-shaped limiting slot 206-1 is 100° to 160°, when the base 101 rotates to the position where the card pin 203 corresponds to the fixed card slot 206-2, the adsorption surface of the marker adsorption mechanism 103 is roughly facing upward, which makes it easy to place the marker 401 on the adsorption surface of the marker adsorption mechanism 103.

[0065] As an optional embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a first handle 202 is also connected to the base 101. The first handle 101 can be directly connected to the base 101, or indirectly connected to the base 101 through the mounting base 201. Preferably, a locking pin 203 is located between the first handle 202 and the base 101, and the axial direction of the first handle 202 is approximately parallel to the length extension direction of the locking pin 203. The base 101 can be manually rotated by holding the first handle 202.

[0066] To facilitate one-handed operation, the distance between the first handle 202 and the locking pin 203 is denoted as H. The value of H ranges from 2cm to 5cm, such as 2cm, 2.5cm, 3cm, 4cm, 4.5cm, or 5cm, etc. After holding the first handle 202 with one hand, the locking pin 203 can be moved by the finger to lift the locking pin 203 out of the fixed slot 206-2 and the arc-shaped limiting slot 206-1, or insert it into the fixed slot 206-2 and the arc-shaped limiting slot 206-1.

[0067] As an optional embodiment, the online non-stop roll material labeling device proposed in this application further includes a locking pin driving mechanism. The locking pin driving mechanism drives the locking pin 203 to rotate, causing the locking pin 203 to insert into and / or leave the arc-shaped limiting groove 206-1 and the fixed locking groove 206-2. At this time, the locking pin driving mechanism replaces the manual operation of the locking pin 203, or works together with the manual operation of the locking pin 203 to achieve the function of the locking pin 203 inserting into and / or leaving the arc-shaped limiting groove 206-1 and the fixed locking groove 206-2.

[0068] For the pin drive mechanism, in one implementation scheme, spring 204 can be selected, such as... Figure 2 As shown, one end of the spring 204 is connected to the locking pin 203, and the other end of the spring 204 can be connected to the mounting base 201, the base 101, or the first handle 202. When the locking pin 203 is manually moved, causing it to disengage from the arc-shaped limiting groove 206-1 and the fixed groove 206-2, the spring 204 is in a stretched state. When the finger releases the locking pin 203, under the tension of the spring 204, the locking pin 203 can automatically return to its original position and re-insert into the arc-shaped limiting groove 206-1 and the fixed groove 206-2.

[0069] For the card pin drive mechanism, in another implementation scheme, magnetic attraction can be used, such as... Figure 4 As shown, a magnet is installed on the locking pin 203, and a corresponding iron block is installed on the mounting base 201 or the base 101. Alternatively, this sticker is installed on the mounting base 201 or the base 101, and a corresponding iron block is installed on the locking pin 203. Manually moving the locking pin 203 disengages it from the arc-shaped limiting groove 206-1 and the fixed locking groove 206-2. The iron block adheres to the magnet. At this point, the finger can release the locking pin 203, but the locking pin 203 will not automatically return to its original position, i.e., it will not automatically insert into the arc-shaped limiting groove 206-1 or the fixed locking groove 206-2.

[0070] In another implementation scheme, a cylinder or electric push rod can be used for the locking pin drive mechanism. In this case, the cylinder body is hinged to the base 101 or the mounting base 201, and the piston rod end is hinged to the locking pin 203. The locking pin 203 can be inserted into and removed from the arc-shaped limiting groove 206-1 and the fixed groove 206-2 by the cylinder or electric push rod. In this case, there is no need to manually move the locking pin 203.

[0071] It should be noted that the pin drive mechanism is not limited to the above structure. Other existing mechanisms that can enable the pin 203 to be inserted into and / or removed from the arc-shaped limiting groove 206-1 and the fixed groove 206-2 are also applicable to this application, and will not be described or limited here.

[0072] As an optional embodiment, the online non-stop roll material labeling device proposed in this application further includes a second handle 205, such as... Figures 1-9 As shown, the second handle 205 is connected to the base 101. The second handle 205 can be directly connected to the base 101, or it can be indirectly connected to the base 101 through other components. The connection method can be bolt connection, welding, or integral molding, etc.

[0073] Preferably, the second handle 205 is approximately arc-shaped, such as... Figure 7 As shown, when the base 101 needs to be rotated 100° to 160° so that the base 101 is rotated to the position corresponding to the locking pin 203 and the fixing slot 206-2, it would be inconvenient to use the base 101 by simply holding the first handle 202. By setting the arc-shaped second handle 205, it is convenient to rotate the base 101 100° to 160° by holding the second handle 205.

[0074] Optionally, such as Figure 3 As shown, the second handle 205 is provided with a radial through groove 205-1, and the other end of the locking pin 203 passes through the radial through groove 205-1. The radial through groove 205-1 can guide the rotation of the locking pin 203 and also prevent the end of the locking pin 203 from bending and deforming.

[0075] Specifically, when the end of the locking pin 203 is inserted into the arc-shaped limiting groove 206-1 and the fixed locking groove 206-2, and the base 101, the drive mechanism 102, and the marker adsorption mechanism 103 rotate together, the locking pin 203 will collide with the groove walls of the arc-shaped limiting groove 206-1 and the fixed locking groove 206-2. At this time, the end of the locking pin 203 is subjected to a large force and is prone to bending and deformation. In this embodiment, by setting a radial through groove 205-1, the end of the locking pin 203 passes through the radial through groove 205-1. At this time, the groove wall of the radial through groove 205-1 contacts the side wall of the locking pin 203, thereby preventing the end of the locking pin 203 from bending and deforming when it collides with the groove walls of the arc-shaped limiting groove 206-1 and the fixed locking groove 206-2.

[0076] In addition, when the base 101 is rotated by holding the second handle 205, the other end of the locking pin 203 passes through the radial through groove 205-1, which makes it easy for the fingers to move the locking pin 203, so that the locking pin 203 can be inserted into and removed from the arc-shaped limiting groove 206-1 and the fixed groove 206-2.

[0077] As an optional embodiment, the marker adsorption mechanism 103 includes a negative pressure tube. The length of the negative pressure tube extends approximately parallel to the rotational axis of the base. The negative pressure tube is connected to an air pipe, allowing a negative pressure environment to be created inside the tube. The adsorption surface of the negative pressure tube is provided with multiple air holes. When a negative pressure environment is created inside the tube, the marker 401 is placed on the adsorption surface and can be adsorbed. Note that at this time, the adhesive surface of the marker 401 faces away from the adsorption surface. When the marker 401 is adhered to the sanitary material 402, the negative pressure tube is inflated to restore normal pressure, at which point the marker 401 adheres to the sanitary material 402.

[0078] By making the length extension direction of the negative pressure tube approximately parallel to the rotation axis of the base, and by making the adsorption surface of the negative pressure tube have multiple air holes, a marker 401 of a corresponding size can be placed on the adsorption surface according to the different widths of the sanitary material 402.

[0079] The sanitary material 402, located below the online non-stop roll labeling device, rests on a conveyor roller. The roller surface is arc-shaped, making the adsorption surface arc-shaped as well. The label 401 is also arc-shaped. When the sanitary material 402 drives the label adsorption mechanism 103 and the base 101 to rotate, the arc-shaped surface of the label 401 is tangent to the arc-shaped surface of the sanitary material 402, allowing the label 401 to adhere firmly to the sanitary material 402. Furthermore, the arc-shaped adsorption surface prevents other parts of the adsorption surface from contacting the surface of the sanitary material 402 when the label is applied, thus avoiding pressure on any bulges or other structures on the surface of the sanitary material 402.

[0080] Optionally, the online non-stop roll labeling device further includes a guiding mechanism for moving the label adsorption mechanism 103 in the radial direction of rotation along the base. As an optional embodiment, the guiding mechanism includes a guide rail 302 and a slider 301 that can slide along the guide rail 302. One of the guide rail 302 and the slider 301 is connected to the base 101, and the other is connected to a negative pressure pipe. The guiding mechanism improves the stability of the label adsorption mechanism 103 during movement and enhances the accuracy of label application 401.

[0081] Optionally, the base 101 can be electrically driven to rotate. For example, the base 101 can be connected to an electric drive mechanism, which drives the base 101 to rotate. The electric drive mechanism can be a transmission system consisting of a motor, a reducer, and a drive shaft. Such transmission mechanisms are relatively mature in the prior art and will not be described or limited here.
