TECHNICAL FIELD
[0001] The utility model belongs to the technical field of sleeve label packaging, especially relates to a double -deck label buffer rack and sleeve label equipment. BACKGROUND
[0002] The sleeve label equipment can automatically cut off the label band and accurately sleeve, and cooperate with the subsequent heat shrinkage process to fix the label on the cylindrical container. The sleeve label machine has excellent high-speed stability. Today, the automatic high-speed sleeve label equipment has been widely applied in various fields.
[0003] The label band usually exists in the form of a roll. However, the length of the label band in a roll is limited, and it often needs to be replaced for a high-speed sleeve label machine. This results in the need to stop the entire sleeve label assembly line for replacement. Some buffer devices have been designed to avoid stopping during the replacement of the roll. Some sleeve label machines already exist, in which a buffer mechanism for storing part of the label band is provided between the feeding mechanism and the sleeve label mechanism. The label band output by the feeding mechanism needs to pass through the buffer mechanism for transmission before reaching the sleeve label mechanism. Since the buffer mechanism can store part of the label band, it can replenish the feeding mechanism without stopping.
[0004] However, as the speed of the sleeve label machine becomes faster, the existing buffer device cannot meet the requirements or needs a larger structure space to realize non-stop during the replacement of the roll.
[0005] Therefore, it is urgent to improve the buffer mechanism and sleeve label equipment in the prior art to better adapt to the above problems with a simple structure. UTILITY MODEL CONTENT
[0006] The utility model aims at providing a double -deck label buffer rack and sleeve label equipment, which can be used as a buffer device to realize non-stop during the replacement of the roll with a simple structure and a small structure space, and make the entire buffer device movable and flexible to adapt to various sleeve label assembly lines.
[0007] The above technical problem is solved by a double-layer label buffer magazine, comprising a base, a guide rail, a first roller unit and a second roller unit, the first roller unit and the second roller unit are both arranged on the guide rail, the guide rail is fixed on the base and extends in the vertical direction, the first roller unit and the second roller unit are arranged on the guide rail and extend in the horizontal direction transverse to the vertical direction, wherein the first roller unit and the second roller unit respectively comprise a back plate and two rows of rollers fixed on one side of the back plate at different heights, the label tape is alternately wound through each roller in the first roller unit and the second roller unit, wherein at least the lower second roller unit has a sliding block fixed on the back plate on the side away from the roller, and the second roller unit is engaged with the guide rail in a way that can slide up and down on the guide rail by means of the sliding block. Here, by designing both the first roller unit and the second roller unit with double-layer rollers, each row of rollers, for example, respectively comprises 6-12 rollers, so that the winding times of the label tape are at least doubled under the premise of basically the same structure space. More label tapes can be stored in the buffer mechanism. In addition, due to the more winding times of the label tape, the force acting on the label tape due to the gravity of the second roller unit is smaller, so that even in a high-speed running assembly line, the label tape is not easy to be twisted and deformed due to excessive tension. This further improves the labeling quality.
[0008] According to an advantageous embodiment, the first roller unit is fixedly arranged at the upper end of the guide rail. Here, the first roller unit is designed to be fixed in position, thereby achieving a simple structure.
[0009] In a preferred scheme, the first roller unit also has a sliding block and is engaged on the guide rail in a way that can slide up and down, wherein the first roller unit also has a locking mechanism for locking the first roller unit relative to the guide rail. Here, the first roller unit is also designed to be movable up and down along the guide rail, which enables flexible adjustment of the height of the first roller unit or the maximum label tape storage capacity according to specific needs.
[0010] Advantageously, the guide rail comprises a first track and a second track parallel to each other, and the first roller unit and the second roller unit comprise two sliding blocks and are engaged on the first track and the second track in a way that can slide up and down by means of the sliding blocks. By providing two tracks and two sliding blocks, the entire double-layer label buffer magazine is more stable in structure, ensuring reliability even in high-speed running and vibrating working scenarios.
[0011] It is also preferred that the first track and / or the second track are designed as an "H" beam extending in the vertical direction, and the slider is able to be inserted into the two lateral openings of the "H" beam. By designing at least one track as an "H" beam and the slider as a structure to be inserted into the "H" beam, the structural reliability of the entire rack is improved, so that the adverse effects such as the inclination of the roller unit caused by the transfer of the rack or other external influences can be resisted by the structure itself.
[0012] It is also advantageous that a turning mechanism is fixed on the back plate of the first roller unit by means of a cantilever, and the turning mechanism comprises an adjusting assembly for swinging the turning mechanism to a predetermined angle relative to the first roller unit. Thereby, the double-layer label buffer rack can be flexibly adapted to various pipeline arrangements, for example, it can be arranged at an angle with the upstream mechanism or the downstream mechanism.
[0013] It is also preferred that the guide rail is able to be displaced relative to the base in the transverse direction and / or that rollers are provided on the bottom of the base. Thereby, the adjustability of the entire double-layer label buffer rack is provided, so that it can be flexibly adapted to various application scenarios.
[0014] It is preferred that the rollers in the two rows of rollers of the first roller unit and / or the second roller unit are arranged staggered relative to each other in the horizontal direction perpendicular to the vertical direction. Thereby, the possibility of interference of the wound label bands with each other can be avoided.
[0015] It is also advantageous that a distance measuring sensor is provided on the second roller unit and the base, respectively, or between the first roller unit and the second roller unit. By providing the distance measuring sensor, the amount of label bands stored in the double-layer label buffer rack can be determined in real time, and the measured data can be transmitted to a higher-level controller, which can adjust the running speed of the feeding system or the downstream according to the data, so as to ensure that there is a sufficient amount of label bands stored in the double-layer label buffer rack at least before the roll is about to be replaced.

[0021] In order to make the purpose, technical scheme and advantage of the utility model more clear, the following combines the drawing and example, and further detailed explanation is made to the utility model. It should be understood that the specific example described here is only used to explain the utility model, and is not used to limit the utility model.
[0022] In the existing sleeve label assembly line, in order to avoid the process of changing label material roll to make the whole sleeve label assembly line continue to run, usually set up buffer mechanism between the label tape supply mechanism and sleeve label mechanism. However, with the increase of sleeve label speed of modern sleeve label equipment, the existing buffer mechanism already can not satisfy the demand. In addition, the existing buffer mechanism occupies the structural space is bigger and not easy to adjust, it is difficult to adapt to various production scenes. Therefore, the application proposes a new double -deck label buffer material frame, with simple structure, less structural space reliably realizes the function of changing label without stopping and with flexible adjustable mode realizes the matching with various production scenes.
[0023] Figure 1A perspective view of a double label buffer magazine 100 according to the present application is shown. The double label buffer magazine 100 comprises a base 1, a guide rail 2 and a first roller unit 3 and a second roller unit 4. The guide rail 2 extends in vertical direction and is fixed on the base 1 in a way that it can be displaced in horizontal direction. That means, the guide rail 2 can be moved in horizontal direction relative to the base 1 and can be locked in the position after the movement. For this purpose, a locking mechanism for locking the relative position of both is provided on the guide rail or the base. Additionally, in order to improve the mobility of the whole double label buffer magazine 100, a plurality of rollers can be provided below the base 1. For example three or four rollers. Such rollers are for example rollers with a self-locking mechanism or a brake mechanism, so that after the movement the double label buffer magazine 100 can be reliably stopped in a defined position.
[0024] By Figure 1 It can be seen that the first roller unit 3 comprises a back plate and two rows of rollers fixed on the same side of the back plate at different heights, here each row of rollers has 10 rollers. However, other numbers of rollers are also possible, for example 6-12 rollers. Each roller here functions like a pulley, for example can rotate around a strut fixed on the back plate. The first roller unit 3 can be fixed positionally on the guide rail 2. But it can also be designed to be movable up and down along the guide rail 2 and to be locked at any selected height by means of a locking member. The locking mechanism can be for example a locking bolt or the like similar device.
[0025] The second roller unit 4 likewise comprises a back plate 5 and two rows of rollers 6 fixed on the same side of the back plate at different heights, here each row of rollers has 10 rollers. However, other numbers of rollers are also possible, for example 6-12 rollers. The number of rollers in each row of rollers of the second roller unit 4 is preferably the same as the number of rollers in each row of rollers of the first roller unit 3. The label tape is alternately wound through each roller in the first roller unit 3 and the second roller unit 4. The second roller unit 4 is arranged in a way that it can slide up and down along the guide rail 2. For this purpose, a sliding block is provided on the back plate 5 of the second roller unit 4, which can be fitted with the "I" shaped track of the guide rail. In Figure 1In the embodiment shown, the back plate has two sliders, the guide rail has two "H" shaped tracks, and the sliders can be inserted into the two lateral openings of the "H" beam. That is, the guide rail comprises a first track and a second track parallel to each other, and the second roller unit comprises two sliders and is engaged on the first track and the second track in a slidable manner by means of the sliders. Similarly, in the case where the first roller unit 3 is designed to be height-adjustable, the first roller unit also comprises two sliders and is engaged on the first track and the second track in a slidable manner by means of the sliders. However, it is also possible to provide only one track or more than two tracks. The second roller unit 4 can move up and down along the guide rail 2 under the pull of the label tape. That is, in the case of replacing the label roll, the label tape stored between the two roller units can be released by reducing the distance between the first roller unit 3 and the second roller unit 4, thereby achieving label replacement without stopping.
[0026] Figure 2 A top view of the double-layer label buffer rack 100 according to the present application is shown. In Figure 2 The engagement of the sliders on the back plate of the first roller unit 3 with the two tracks is clearly shown. Here, the two rows of rollers in the first roller unit 3 are arranged in alignment. However, it is also preferred that the rollers in the two rows of rollers of the first roller unit 3 and / or the second roller unit are arranged staggered in a horizontal direction perpendicular to the vertical direction. In addition, a turning mechanism 8 is fixed on the back plate of the first roller unit 3 by a cantilever 7. The turning mechanism 8 comprises an adjustment assembly 9 for swinging the turning mechanism to a predetermined angle relative to the first roller unit 3. In this way, the label tape can be flexibly turned to the desired direction.
[0027] Figure 3 is Figure 1 A side view of the double-layer label buffer rack 100 is shown. It can be seen here that the guide rail 2 comprises two tracks 10 parallel to each other. The first roller unit 3 and the second roller unit 4 are arranged at the two ends of the guide rail 2, respectively, wherein the second roller unit 4 can move up and down along the tracks 10 under the pull of the label tape. Each roller unit comprises a back plate and two rows of rollers, for example 10 rollers, fixed on the same side of the back plate at different heights. Here, the two rows of rollers are aligned vertically, but they can also be arranged staggered in a horizontal direction.
[0028] Although not shown, a spacing measurement sensor can also be provided on the second roller unit and the base, respectively, or between the first roller unit and the second roller unit. The spacing measurement sensor is connected to the higher-level controller by a signal, so that the measured spacing can be transmitted to the higher-level controller. By means of the measured spacing, it can be inferred that the amount of label web stored between the first roller unit 3 and the second roller unit 4. In addition, based on the amount of label web stored between the first roller unit 3 and the second roller unit 4, the controller can determine whether the amount of label web is sufficient to ensure continuous operation of the downstream mechanism during the process of replacing the label roll. According to the determination result, for example, if the amount of label web stored is insufficient, the controller can drive the feeding mechanism to increase the feeding speed and / or reduce the consumption speed of the downstream labeling mechanism, so as to increase the amount of label web stored between the first roller unit 3 and the second roller unit 4.
[0029] Overall, the labeling equipment proposed in the present application comprises a feeding mechanism for supplying label web, a conveying mechanism, and a labeling mechanism and a main heat shrinkage furnace, wherein the labeling equipment further comprises the above-mentioned double-layer label buffer rack between the feeding mechanism and the labeling mechanism.
[0030] To sum up, the labeling equipment in the embodiments of the present application realizes the function of label replacement without shutdown during high-speed operation by means of the double-layer label buffer rack. In addition, by designing two rows of rollers for the two roller units, more label web can be stored in the buffer mechanism without increasing the structural space. In addition, since the label web is wound more times, the force acting on the label web due to the gravity of the second roller unit is smaller, so that the label web is not easy to be twisted and deformed due to excessive tension, even in a high-speed operation assembly line, which further improves the labeling quality. Further, the entire double-layer label buffer rack can be adjusted in structure, so that it can be adapted to various production scenes, thereby improving the application range.
