Embodiment 1

• Ein Etikettenglättungsmechanismus einer vollautomatischen Etikettiermaschine für Profilflächen umfasst Montagesäulen 2, die spiegelsymmetrisch an den beiden Seiten eines Fördermechanismus 100 angeordnet sind und deren Mittelachse senkrecht zur Förderebene ist, wobei um die Außenseite der Montagesäulen 2 mehrere gleichmäßig verteilte radiale Teleskopstangen 3 vorgesehen sind, wobei ein Ende der Teleskopstange 3 fest mit der Montagesäule 2 verbunden und das andere Ende der Teleskopstange fest mit einer Stützwalze 4 verbunden ist, wobei die Mittelachsen der Stützwalzen und die Mittelachsen der Montagesäulen parallel zueinander sind, wobei die Stützwalzen 4 gemeinsam von einem Etikettenglättungsband 1 umschlossen sind, wobei das Etikettenglättungsband 1 mit den Stützwalzen 4 in Eingriff steht, um sie anzutreiben, wobei das Etikettenglättungsband 1 an der dem Fördermechanismus 100 abgewandten Seite mit einer Aufspanneinheit 5 versehen ist, wobei die Aufspanneinheit 5 fest mit dem Maschinenkörper verbunden ist.

As in 1 to 5 shown, the teachings provide the following technical solution:

• A label smoothing mechanism of a fully automatic labeling machine for profile surfaces comprises mounting columns 2 that are mirror-symmetrical on both sides of a conveyor mechanism 100 are arranged and whose central axis is perpendicular to the conveyor plane, with around the outside of the mounting columns 2 several evenly distributed radial telescopic rods 3 are provided, one end of the Telescopic pole 3 firmly to the mounting column 2 connected and the other end of the telescopic rod fixed to a support roller 4th is connected, wherein the central axes of the support rollers and the central axes of the mounting columns are parallel to each other, the support rollers 4th together from a label smoothing tape 1 are enclosed, with the label smoothing tape 1 with the backup rolls 4th is engaged to drive it, the decalfing tape 1 on the funding mechanism 100 remote side with a clamping unit 5 is provided, the clamping unit 5 is firmly connected to the machine body.

In this embodiment are around the outside of the mounting column 2 several telescopic poles 3 evenly arranged. One end of the telescopic pole 3 is fixed to the mounting column 2 connected and the other end of the telescopic rod is fixed to a support roller 4th connected. The backup rolls 4th are shared by a label smoothing tape 1 enclosed. As a result, a label smoothing mechanism is formed which consists of at least the label smoothing tape 1 , the mounting column 2 , the telescopic poles 3 and the backup rolls 4th consists. The label straightening tape 1 encloses the support rollers 4th , whereby a roller structure is formed. In use, it can roll along the outside of the packaging bottle to flatten the label. If the outside of the packaging bottle has an uneven profile surface, the telescopic rods 3 be retracted or extended according to the uneven part of the profile surface, so that the label smoothing tape 1 always rests against the outside of the packaging bottle so that the label can be flattened. Compared to the conventional smoothing roller or smoothing plate, the label smoothing mechanism for profile surfaces of the gauges has a better smoothing effect. Therefore, the feature of the invention is that the label can be smoothed on the profile surface of the packaging bottle.

The mounting column 2 has a core rod 21st and a socket 22nd which is arranged coaxially and movably around the core rod with the core rod. The core rod 21st is firmly connected to the machine body. The socket 22nd is frictionally engaged with the core rod 21st connected and encloses the core rod 21st . A sleeve can be rotated due to the frictional connection. The ends of the telescopic poles 3 are firmly attached to the outside of the socket 22nd attached. In use, the labeling mechanism brings 200 a label on the packaging bottle. Then the packaging bottle is removed from the conveyor mechanism 100 transported to the label flattening mechanism. The outer label straightening tape 1 is in contact with the packaging bottle. The friction force causes the bushing 22nd relative to the core rod 21st rotated so that the outer label smoothing tape 1 is pressed continuously against the packaging bottle in order to flatten the label.

The telescopic pole 3 has a sleeve 31 , a support rod 32 and a feather 33 that are coaxial. The sleeve 31 is on the outside of the can 22nd attached. One end of the support rod 32 is fixed to the backup roller 4th connected. The other end of the support rod extends into the sleeve 31 and is slidable with the sleeve 31 connected. The feather 33 is in the sleeve 31 attached. The sleeve 31 and the support rod 32 are by the pen 33 elastically connected. The sleeve 31 who have favourited the support rod 32 and the pen 33 form the telescopic pole. This allows the support rod 32 elastic into the sleeve 31 and be pushed out of it. The support rod 32 has a delimiting structure in the sleeve 31 on. The boundary structure is similar to the structure of an existing spring-loaded telescopic pole. For example, at the end of the sleeve 31 an end cap with a smaller diameter is provided. The support rod 32 is provided with a washer that is in the sleeve 31 can slide, whereby a delimiting structure is formed. This type of structure is a conventional technical solution and is not described in detail in the teachings. This restraining structure can prevent the support rod 32 out of the sleeve 31 falls out. The support rod pushes when it comes into contact with the packaging bottle 32 the backup roll 4th against the surface of the packaging bottle and can be telescoped according to the unevenness of the surface of the packaging bottle, so that the outer label smoothing tape 1 can always rest on the surface of the packaging bottle.

The label straightening tape 1 has a rubber layer 11 and a contact layer 12 on. The contact layer 12 sticks to the outside of the rubber layer 11 . The rubber layer 11 is on the inside with several first teeth 13 Mistake. The contact layer 12 consists of fleece or leather. On the outside of the support roller 4th are second teeth 41 provided that with the first teeth 13 are engaged. The rubber layer 11 and the first teeth 13 are made of rubber material, which has good toughness and is suitable for multiple bending and folding. The contact layer 12 made of fleece or leather can protect the surface of the product to avoid friction damage. The first teeth provided on the inside 13 can with the second teeth 41 on the outside of the backup roll 4th are engaged. This can cause the label smoothing tape to slip 1 be avoided in the power transmission, so that the label smoothing tape 1 and the backup rolls 4th can be moved synchronously. In the event of a deformation of the label smoothing tape due to the telescopic movement of the telescopic rods, the first teeth and the second teeth in the recessed part can separate from one another. Because the decaling tape is pressed and the recessed portion is only a relatively small part of the overall interlocking structure, most of the portion will still remain engaged, allowing the decaling tape to be reset and not come loose.

The clamping unit 5 includes a spring-loaded telescopic rod 51 , a first turning bar 52 and two second pivot bars 53 . The central axis of the spring-loaded telescopic rod is vertical to the central axis of the mounting column. The central axes of the first rod and the second rotating rods are parallel to the central axis of the mounting column. One end of the sprung telescopic rod 51 is attached to the machine body. The other end of the sprung telescopic rod is with the first pivot rod 52 rotatably connected (the rotary connection is made by a bearing). The first rotating rod can be moved back and forth by the spring-loaded telescopic rod along the central axis of the spring-loaded telescopic rod in the direction of the mounting column. The telescopic movement of the spring-loaded telescopic rod can be driven by a conventional small cylinder or adjusted by the spring extension. The two second rotating rods are rotatably connected to the machine body (the second rotating rods 53 are rotatably connected to the machine body by a bearing connection) and symmetrically on both sides of the first rotating rod 52 arranged. The first turning pole 52 lies on the outside of the label straightening tape 1 . The two second turning bars 53 lie on the inside of the label smoothing tape 1 . The first turning pole 52 and the second pivot bars 53 are each rotatable with the label smoothing tape 1 connected. Through the clamping unit 5 can occur during the movement of the decaling tape 1 the length of the label straightening tape 1 by stretching the spring-loaded telescopic rod 51 be compensated so that the label smoothing tape 1 always with the back-up rollers 4th can be held in the engaged state to avoid loosening.

The angle between two adjacent telescopic poles 3 is 5 ° to 45 ̊ and can be adjusted according to the degree of curvature of the outer contour of the packaging bottle so that the label smoothing tape 1 under the action of the telescopic rods 3 can fit snugly against the outside of the packaging bottle.

Embodiment 2

As in 6th shown, the second embodiment differs from the first embodiment only in that the ends of the telescopic rods 3 each fixed with a support plate 4a are connected. The support plates 4a are arched. The outside of each support plate 4a is with second teeth 41 provided with the label smoothing tape 1 are engaged. The curvature of the support plates 4a is larger than that of the backup rolls 4th which makes them suitable for packaging bottles with a lesser degree of unevenness in the outer contour.

The functioning and application of the invention are as follows: In use, the labeling mechanism brings 200 a label on the packaging bottle. Then the packaging bottle is removed from the conveyor mechanism 100 transported to the label flattening mechanism. The outer label straightening tape 1 is in contact with the packaging bottle. The friction force causes the bushing 22nd relative to the core rod 21st rotated so that the outer label smoothing tape 1 continuously presses against the packaging bottle to flatten the label. The sleeve 31 who have favourited the support rod 32 and the pen 33 form the telescopic pole. This allows the support rod 32 elastic into the sleeve 31 and be pushed out of this. The support rod 32 has a delimiting structure in the sleeve 31 on that can prevent the support rod 32 from the rod sleeve 31 falls out when in contact with the packaging bottle. The support bars 32 and the backup rolls 4th can continuously press against the surface of the packaging bottle and can be telescoped to match the unevenness of the surface of the packaging bottle, so that the outer label smoothing tape 1 can always lie close to the surface of the packaging bottle.

Finally, it should be noted that the preceding description only represents preferred exemplary embodiments of the teachings and is not intended to restrict the teachings.
