Abstract
Description
Technical Field
[0001] This application relates to the field of ampoule production equipment technology, and in particular to a fully automatic labeling device. Background Technology
[0002] An ampoule is a type of heat-sealed hard glass container, commonly used to store injectable drugs, vaccines, serums, and also for packaging injectable liquids and oral liquids; its capacity is generally 1 to 25 ml.
[0003] Currently, in pharmaceutical manufacturing plants, after ampoules are filled with liquid or preparation drugs and sealed, a labeling machine is used to affix labels with relevant information to the outside of the ampoules. Typically, ampoules are arranged along the width of the conveyor belt and placed at intervals on the conveyor belt. As the conveyor belt passes through the working area of the labeling machine, after the labels are affixed, the ampoules are transported by the conveyor belt to the receiving position, where they fall into the collection box.
[0004] However, current labeling machines have problems such as ampoules being easily damaged and labels being easily scratched during the labeling process, which urgently need to be solved. Utility Model Content
[0005] To achieve the above objectives, this application proposes a fully automatic labeling device, comprising: a frame and a feeding mechanism, a labeling mechanism, a conveying mechanism, and a discharging mechanism disposed on the frame; the labeling mechanism includes a bottle roll and a bottle stop block; a groove adapted to the width of the label to be applied is formed on the bottle roll; two horizontal bars are provided on the contact surface between the bottle stop block and the ampoule, and the distance between the horizontal bars is the same as the width of the groove.
[0006] The above technical solution involves creating a groove on the bottle roll that matches the width of the label to be applied, which can accurately accommodate and position the label, facilitating subsequent labeling operations. The distance between the two horizontal bars of the bottle stop block is the same as the width of the groove, ensuring that the ampoule accurately aligns with the label during the labeling process and guaranteeing the accuracy of the labeling position.
[0007] Specifically, the groove depth is the same as the thickness of the label to be affixed.
[0008] With the above technical solution, the groove depth is the same as the thickness of the label to be applied. This design further improves the positioning accuracy of the label in the groove, prevents the label from shaking or shifting in the groove, ensures the stability of the label during the conveying and application process, and thus improves the labeling quality.
[0009] Specifically, the groove depth is 1.5mm.
[0010] Specifically, a silicone buffer layer is set at the bottom of the groove.
[0011] The above technical solution involves setting a silicone buffer layer at the bottom of the groove, which acts as a buffer during the label's entry into the groove and during conveying, preventing the label from being damaged by excessive impact. It also reduces friction between the label and the bottom of the groove, extending the service life of the label and the bottle roll.
[0012] Specifically, the crossbars are made of stainless steel.
[0013] Specifically, the surface roughness of the contact surface between the crossbar and the ampoule is Ra≤0.8μm.
[0014] Specifically, the labeling mechanism also includes a tensioning unit; the tensioning unit is connected to the bottle roll and is configured to apply a preload when the label contacts the ampoule.
[0015] By adjusting the tensioning unit, you can ensure that there is a suitable adhesion between the label and the ampoule, avoiding damage to the label or breakage of the ampoule due to excessive pressure, and also preventing the label from not adhering firmly due to insufficient pressure.
[0016] Specifically, the preload is 0.05 to 0.15 MPa.
[0017] In the above technical solution, the pre-tightening force between the label and the ampoule is kept constant at 0.05-0.15MPa, which provides a precise pressure control range for the labeling process, making the labeling effect more stable and reliable, and ensuring that the label is firmly attached to the ampoule.
[0018] Specifically, the distance between the two horizontal bars is 23mm ± 0.5mm.
[0019] The above technical solution provides specific values and tolerance ranges for the horizontal spacing, ensuring the positioning accuracy of ampoules during the labeling process and ensuring that ampoules from different batches can be accurately affixed to the labels.
[0020] Specifically, the space between the groove and the two horizontal bars is symmetrically arranged.
[0021] The above technical solution, with its symmetrical arrangement of space between the groove and the two horizontal bars, ensures that the ampoule is subjected to uniform force during labeling, further improving the accuracy of the labeling position and the stability of the labeling quality, and reducing deviations and errors in the labeling process.
[0022] Compared with the prior art, the advantages of this application are:
[0023] (1) The precise fit between the groove and the horizontal bar of the bottle stop (such as groove depth 1.5mm, spacing tolerance ±0.5mm) ensures the accuracy of label positioning and ampoule alignment, avoiding label offset or bottle damage.
[0024] (2) A silicone buffer layer is added to the bottom of the groove to protect the label from impact and reduce friction loss; the crossbar is made of stainless steel with a surface roughness of ≤0.8μm, which takes into account both durability and bottle protection.
[0025] (3) The symmetrical design of the groove and crossbar space, the adjustable tensioning unit and tolerance control enable the device to adapt to ampoules and labels of different sizes, improving the versatility of the equipment;
[0026] (4) The constant pressure control of the tensioning unit (0.05~0.15MPa) ensures that the label is firmly attached and does not damage the bottle. Attached Figure Description

[0033] In the following detailed description, reference is made to the accompanying drawings, which form part of the detailed description and illustrate illustrative specific embodiments in which the present application may be practiced. In this regard, directional terms such as “top,” “bottom,” “left,” “right,” “up,” “down,” etc., are used with reference to the orientation of the described figures. Because components of the embodiments can be positioned in several different orientations, directional terms are used for illustrative purposes and are by no means limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present application. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present application is defined by the appended claims.
[0034] like Figures 1 to 3 As shown, a fully automatic labeling device includes: a frame 1 and a feeding mechanism 2, a labeling mechanism 3, a conveying mechanism 4, and a discharging mechanism 5 disposed on the frame 1; the labeling mechanism 3 includes a bottle roll 3a and a bottle stop block 3c; a groove 3b adapted to the width of the label to be applied is formed on the bottle roll 3a; two horizontal bars 3d are provided on the contact surface between the bottle stop block 3c and the ampoule bottle, and the distance between the horizontal bars 3d is the same as the width of the groove 3b.
[0035] By creating a groove 3b on the bottle roll 3a that is adapted to the width of the label to be applied, the label can be accurately accommodated and positioned, facilitating subsequent labeling operations; the distance between the two horizontal bars 3d of the bottle stop block 3c is the same as the width of the groove 3b, so that the ampoule can accurately correspond to the label during the labeling process, ensuring the accuracy of the labeling position.
[0036] More specifically, the depth of groove 3b is the same as the thickness of the label to be applied. In addition, this design further improves the positioning accuracy of the label in groove 3b, prevents the label from shaking or shifting in groove 3b, ensures the stability of the label during the conveying and application process, and thus improves the quality of labeling.
[0037] Preferably, the depth of groove 3b is 1.5mm.
[0038] Preferably, a silicone buffer layer 3e is provided at the bottom of the groove 3b.
[0039] By setting a silicone buffer layer 3e at the bottom of the groove 3b, a buffering effect is provided during the label's entry into the groove 3b and during conveying, preventing the label from being damaged by excessive impact. At the same time, it can also reduce the friction between the label and the bottom of the groove 3b, extending the service life of the label and the bottle roll 3a.
[0040] Preferably, the crossbar 3D is made of stainless steel.
[0041] Preferably, the surface roughness of the contact surface between the crossbar 3d and the ampoule is Ra≤0.8μm.
[0042] Preferably, the labeling mechanism 3 further includes a tensioning unit; the tensioning unit is connected to the bottle roll 3a, and the tensioning unit is configured to apply a pre-tightening force when the label contacts the ampoule. Adjusting the tensioning unit can ensure that there is a suitable adhesion force between the label and the ampoule, avoid damage to the label or breakage of the ampoule due to excessive pressure, and also prevent the label from being firmly attached due to insufficient pressure.
[0043] In this embodiment, the preload is 0.05 to 0.15 MPa.
[0044] In the above technical solution, the pre-tightening force between the label and the ampoule is kept constant at 0.05-0.15MPa, which provides a precise pressure control range for the labeling process, making the labeling effect more stable and reliable, and ensuring that the label is firmly attached to the ampoule.
[0045] In this embodiment, the distance between the two horizontal bars 3d is 23mm±0.5mm. The specific value and tolerance range of the distance between the horizontal bars 3d are given, which ensures the positioning accuracy of the ampoule during the labeling process and ensures that ampoules from different batches can be accurately affixed to the label.
[0046] In this embodiment, the space between the groove 3b and the two horizontal bars 3d is symmetrically arranged, which makes the ampoule bottle subjected to uniform force when labeled, further improving the accuracy of the labeling position and the stability of the labeling quality, and reducing deviations and errors in the labeling process.
[0047] In one specific embodiment, the crossbeam located at the front end of the bottle-blocking block is installed at the front end of the bottle-blocking block by welding, thus reducing the modification cost and making it applicable to most existing film-applying equipment.
[0048] In this embodiment, the silicone buffer layer 3e disposed in the groove is also required to have a hardness of 50HA.
[0049] In another specific embodiment, such as Figure 4 As shown, the tensioning unit 7 includes a first servo motor, a second servo motor, a winding machine 7a, and a low-inertia shaft 7c. Specifically, the label 7b is wound around the winding machine 7a and the low-inertia shaft 7c, and extends out from the low-inertia shaft 7c to enter the bottle winding belt 3a. The winding machine 7a is driven by the first servo motor, and the low-inertia shaft 7c is driven by the second servo motor. The first and second servo motors are controlled by a host computer or PLC, so that the rotational speeds of the first and second servo motors are different, thereby ensuring that the preload force when the label 7b contacts the ampoule is constant between 0.05-0.15 MPa.

In this way, this application also aims to cover such modifications and alterations if they fall within the scope of the claims and their equivalents. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims.
