Description

Technical Field

[0001] This utility model relates to the technical field of rotary labeling machines, and in particular to an active drive device for a rotary labeling machine bottle holder. Background Technology

[0002] In the production and packaging processes of products in the food, pharmaceutical, and daily chemical industries, labeling machines are key equipment for automating label application. Their operating efficiency and structural design directly affect the production rhythm and packaging quality of products, and they have become an indispensable core component of modern production lines.

[0003] Existing labeling machines typically include a drive unit for conveying products to be labeled (such as bottles) along a preset path. This drive unit is equipped with several bottle holders at intervals for positioning and placing the bottles. Through the continuous operation of the drive unit (such as a chain drive mechanism, belt drive mechanism, etc.), the bottles can be conveyed sequentially to the corresponding work stations of the labeling mechanism. When the bottle arrives at the labeling station, in order to ensure that the label can be accurately and flatly affixed to the bottle's perimeter, the bottle holders need to drive the bottle to rotate around its own axis, so that the label output by the labeling mechanism can complete the affixing action synchronously with the rotation of the bottle, thereby achieving the operational requirements of stable circumferential labeling or labeling at a specified angle.

[0004] To achieve the self-rotation function of the bottle holder, the industry currently adopts a technical solution of setting additional transmission components (such as gear sets, friction wheels, synchronous belt pulleys, etc.) in the transmission path of the drive device. Through the direct contact or meshing of the transmission component with the bottom or side wall of the bottle holder, the power of the drive device is transmitted to the bottle holder, thereby driving the bottle holder to rotate around its own axis. However, this direct drive method has significant drawbacks: in order to ensure effective power transmission between the transmission component and the bottle holder, a connecting structure adapted to the transmission component (such as a drive shaft, meshing gear ring, etc.) needs to be extended at the bottom end of the bottle holder, resulting in a significant increase in the overall length of the bottle holder.

[0005] The increase in bottle tray length directly results in a significant increase in the vertical space occupied by the drive unit. This not only makes it difficult to reduce the overall size of the labeling machine, but also restricts its installation and use in production scenarios with limited space (such as small production lines and workshops with densely packed multi-equipment layouts). It cannot meet the current industry's development needs for miniaturization and compactness of equipment. At the same time, the additional transmission components may also increase the structural complexity of the drive unit, increase the manufacturing and maintenance costs of the equipment, and hinder the improvement of the labeling machine's economy and practicality. Utility Model Content

[0006] The purpose of this invention is to provide an active drive device for a rotary labeling machine bottle holder, which can reduce the length of the bottle holder, thereby reducing space occupation and making it suitable for device miniaturization.

[0007] The objective of this utility model is achieved through the following technical solution:

When the bottle is conveyed to the external labeling mechanism, it can rotate to complete the labeling.

Detailed Implementation

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. These descriptions are intended to aid in understanding the utility model but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] See Figure 1 and Figure 2 This embodiment relates to an active drive device for a rotary labeling machine bottle holder, including a bracket 1, a rotatable conveyor mounted on the bracket 1, a rotatable bottle holder mounted on the conveyor, a rotatable bottle pressing device mounted above the bottle holder, and a drive unit that drives and connects the conveyor and the bottle holder respectively.

[0027] During labeling, the bottle is placed on the bottle holder and pressed and fixed by the bottle pressing component. Driven by the drive component, the conveyor can rotate relative to the bracket 1 and convey the bottle along the preset path in a revolution manner. At the same time, the bottle holder can rotate relative to the conveyor so that the bottle can be labeled in a rotation manner when it is conveyed through the external labeling mechanism. The bottle pressing component rotates accordingly with the revolution and rotation of the bottle.

[0028] Specifically, the conveying component includes a main shaft 2 and a turntable 3 mounted on the main shaft 2; the main shaft 2 is vertically mounted on the bracket 1 via a first bearing seat 4, and the bracket 1 has a shaft hole that can mate with the first bearing seat 4; when the main shaft 2 is mounted on the bracket 1, the top end of the main shaft 2 extends out of the top of the bracket 1 and connects to the turntable 3, and the bottom end of the main shaft 2 extends out of the bottom of the bracket 1 and is connected to the drive component via a first transmission mechanism; the first bearing seat 4 contains a first bearing, which is sleeved on the main shaft 2; when the drive component is started, it generates torque, which is transmitted through the first transmission mechanism, and the rotational motion of the main shaft 2 drives the turntable 3 to rotate relative to the bracket 1.

[0029] The turntable 3 has a circular disc structure and at least two bottle-holding stations are provided on the turntable 3. The bottle-holding stations are arranged at equal intervals around the center of the turntable 3, and each bottle-holding station is provided with a corresponding bottle holder. When the turntable 3 rotates, it forms a circular conveying path so that the bottle can revolve under the drive of the turntable 3 and pass through the labeling mechanism to complete the labeling.

[0030] The bottle holder includes a support shaft 5 and a tray 6 mounted on the support shaft 5. The support shaft 5 is vertically mounted at the bottle-holding position of the turntable 3 via a second bearing seat 7. The turntable 3 has a shaft hole at the bottle-holding position that can mate with the second bearing seat 7. When the support shaft 5 is mounted on the turntable 3, the top end of the support shaft 5 extends out of the top of the turntable 3 and connects to the tray 6. The bottom end of the support shaft 5 extends out of the bottom of the turntable 3 and is connected to the drive component via a second transmission mechanism. The second bearing seat 7 contains a second bearing, which is sleeved on the support shaft 5. When the drive component is started, it generates torque, which is transmitted through the second transmission mechanism. The rotational movement of the support shaft 5 causes the tray 6 to rotate relative to the turntable 3.

[0031] Since the driving component is driven by the first transmission mechanism and the second transmission mechanism, when the driving component is started, it can simultaneously drive the turntable 3 and the tray 6 to rotate. This not only enables the bottle to revolve around the center of the turntable 3 to be conveyed through the labeling mechanism, but also enables the bottle to rotate around its own axis during the conveying process to cooperate with the labeling mechanism to complete the labeling.

[0032] The driving component is a stepper motor 8 as in the prior art. The motor is located at the bottom of the bracket 1. The output shaft of the stepper motor 8 is equipped with a drive gear 9 and a drive pulley 10. The drive gear 9 is connected to the main shaft 2 through a first transmission mechanism, and the drive pulley 10 is connected to the support shaft 5 through a second transmission mechanism. When the output shaft of the stepper motor 8 rotates, it is simultaneously driven by the first and second transmission mechanisms to drive the turntable 3 and the tray 6 to rotate.

[0033] The first transmission mechanism includes a gear seat 11, a rotatable gear shaft 28 mounted on the gear seat 11, a first driven gear 12 and a second driven gear 13 mounted on the gear shaft, and a third driven gear 14 mounted on the bottom end of the main shaft 2. The gear seat 11 is fixedly mounted on the bracket 1. A sleeve 29 is mounted on the gear shaft. The sleeve 29 is connected to the first driven gear 12 and the second driven gear 13 so that a gap is formed between the first driven gear 12 and the second driven gear 13, and the two drive gears rotate synchronously. The first driven gear 12 and the driving gear 9 mesh with each other to form a first-stage gear transmission, and the second driven gear 13 and the third driven gear 14 mesh with each other to form a second-stage gear transmission. When the output shaft of the stepper motor 8 rotates, it drives the main shaft 2 to rotate through the two-stage gear transmission.

[0034] The second transmission mechanism includes a pulley seat 15, a pulley shaft 16 rotatable on the pulley seat 15, a first driven pulley 17 and a second driven pulley 18 on the pulley shaft 16, and a third driven pulley 19 on the bottom end of the support shaft 5. The pulley seat 15 is fixedly mounted on a bracket 1, and the bracket 1 has a through hole that can mate with the pulley seat 15. The bottom end of the pulley shaft 16 extends through the pulley seat 15, passes through the bottom surface of the bracket 1, and connects to the first driven pulley 17. The top end of the pulley shaft 16 extends through the top surface of the pulley seat 15 and connects to the second driven pulley 18. A first synchronous belt 20 is wound between the driving pulley 10 and the first driven pulley 17 to form a first-stage synchronous belt drive. A second synchronous belt 21 is wound between the second driven pulley 18 and the third driven pulley 19 to form a second-stage synchronous belt drive. When the output shaft of the stepper motor 8 rotates, it drives the support shaft 5 to rotate through the two-stage synchronous belt drive.

[0035] The bracket 1 has a first tensioning pulley 22 on its bottom surface, which is close to the first driven pulley 17 to tension the first synchronous belt 20. A second tensioning pulley 23 is provided on the pulley seat 15, which is close to the second driven pulley 18 to tension the second synchronous belt 21. By tensioning the two synchronous belts, slippage between the synchronous belts and the pulleys is avoided, thereby ensuring transmission stability. To further improve stability, a third tensioning pulley 27 can be provided near the turntable 3 as needed. The first tensioning pulley 22, the second tensioning pulley 23, and the third tensioning pulley 27 have the same structure.

[0036] In this embodiment, the bottle-holding stations are arranged at equal intervals around the center of the turntable 3. The third driven pulley 19 on the support shaft 5 at each bottle-holding station forms a circular conveying path when the turntable 3 rotates. The tail end of the second synchronous belt 21 is located on the second driven pulley 18. The head end of the second synchronous belt 21 passes around the third driven pulley 19 on the conveying path in sequence, and then returns to the second driven pulley 18 to connect with the tail end of the second synchronous belt 21 to form a closed loop.

[0037] In this embodiment, the second transmission mechanism adopts a two-stage synchronous belt drive, which can complete the labeling by driving the bottle to rotate via the tray 6 while the turntable 3 drives the bottle to revolve. Since the first driven pulley 17 and the second driven pulley 18 are not installed on the turntable 3, they can be replaced without disassembling the entire turntable 3. By replacing the first driven pulley 17 and the second driven pulley 18 with different sizes, different transmission ratios can be formed, thereby flexibly changing the rotation speed of the tray 6 so that the rotation speed of the bottle can match the labeling speed of the labeling mechanism. At the same time, it avoids interference with the components or structures on the turntable 3 due to the selection of different sizes of driven pulleys. Since the transmission is carried out on the side of the turntable 3, the length of the support shaft 5 can be reduced, the space occupied can be reduced, and it is suitable for device miniaturization.

[0038] The bottle pressing component includes an electric rotating frame 24 mounted on a support 1, a bottle pressing head 25 mounted on the electric rotating frame 24 that can rotate and move up and down, and a cylinder 26 that drives and connects to the bottle pressing head 25. The bottle pressing head 25 is arranged one-to-one with the tray 6. When the bottle is placed on the tray 6, the cylinder 26 drives the bottle pressing head 25 to move downward and engage with the bottle mouth to form a fixing force at both ends of the bottle's axial direction, thereby completing the pressing and fixing of the bottle. When the turntable 3 drives the bottle to revolve and be conveyed, the rotation of the electric rotating frame 24 drives the bottle pressing head 25 to rotate accordingly. When the tray 6 drives the bottle to rotate, the bottle pressing head 25 can rotate accordingly with the rotation of the bottle.

[0039] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
