Since labeling is required to be performed with the container upright, prior art labeling devices are generally only suitable for use with free-standing containers such as various standing bottles or jars. For some containers which cannot stand alone, such as flexible packaging containers or elongated containers, such as popsicles and the like, sleeve labeling cannot be realized by the existing sleeve labeling equipment. In fact, such packaging containers, unlike traditional bottles or cans, are increasingly used, as nowadays more and more attention is paid to the individualization of the packaging.
Therefore, it is desirable to provide a new labeling device and labeling method that can automatically label containers or products that cannot or cannot easily stand.
SUMMERY OF THE UTILITY MODEL
The object of the present invention is to provide a labeling device for labeling containers that are not easy to stand, by means of which one or more of the technical problems of the prior art can be solved.
According to one aspect of the utility model, the above object is achieved by a labeling apparatus for labeling containers that are not easily standing, comprising a transport device and a labeling device, wherein the transport device comprises a first and a second conveyor belt that can be operated continuously in a circulating manner, a plurality of container receiving means for receiving individual containers being arranged fixedly on the outside of the first and second conveyor belt, respectively, wherein the first conveyor belt serves for transporting the containers through the labeling device, the second conveyor belt is arranged downstream of the labeling device in a locally adjoining manner to the first conveyor belt, wherein the first conveyor belt is assigned a tilting mechanism and a holding mechanism, which tilting mechanism is designed to tilt at least a part of the first conveyor belt about its direction of movement and to bring the containers through the labeling device in an upright state by means of the holding mechanism, wherein the labeling apparatus further comprises an ejector mechanism arranged in the region of abutment of the first and second conveyor belts for ejecting labeled containers from the receiving members of the first conveyor belt into the receiving members of the second conveyor belt, wherein the second conveyor belt is provided with a stop at the side facing away from the first conveyor belt.
The first conveyor belt and the second conveyor belt are preferably of identical design, particularly preferably move synchronously. But may be unsynchronized so long as it is ensured that the container receiving members of both belts are substantially aligned in the abutment region when they are running, e.g. only keeping the running speeds of both belts substantially the same. On the outer circumference of the two conveyor belts, i.e. on the side facing away from the drive mechanism, container receiving members are preferably arranged uniformly at the same distance. In this application, a "conveyor belt" is to be understood in a broad sense, and includes not only a belt for conveyance, but also a conveyor chain and the like. The outside of the conveyor belt refers to the side that is directed outward during the conveying operation. The moving direction of the conveyor belt refers to the moving direction of the conveyor belt along the horizontal direction when the conveyor belt runs, and the moving direction generally corresponds to the longitudinal direction of the labeling device. Accordingly, the standing force state is that the finger label device stands in the height direction.
Advantageously, the container receiving means are designed as U-shaped channels, which are evenly distributed on the outside of the first and second conveyor belts. Obviously, the container receiving member may also have other suitable shapes, such as semi-circular, C-shaped, etc., depending on the shape of the container to be labeled, as long as it is capable of receiving a single container.
The tilting mechanism is advantageously designed as a guide surface that is arched in the lateral direction, on which the first conveyor belt is guided, which guide surface extends over the labeling means and is designed to be vertical at the same time as the guide surface at the labeling position of the labeling means. That is, the guide surface is designed as a curved surface that is reversed, along which the first conveyor belt moves, so as to be also reversed following the curved surface. It is also conceivable to design the tilting mechanism as a movable mechanical mechanism, for example as a tilting bar or a tilting plate which can be driven electrically, pneumatically or hydraulically. But a curved surface designed to be stationary is preferred.
Preferably, the holding mechanism comprises a support and a pressing element, wherein the pressing element is fixed on the support, and the support is fixedly connected with a frame of the labeling device. The function of the retaining mechanism is to ensure that in the erected state the container does not fall out or slide off the container receiving member.
Advantageously, the pressing element is shaped to conform to the outer contour of the container. For example, the outer contour of the ice-lolly is rod-shaped with a pronounced depression, so that the pressing element can be designed as a press rod which can engage in the depression of the outer contour of the ice-lolly and thus reliably remain free from falling even in the upright position.
Preferably, the ejector mechanism comprises a fixed support and an ejector fixed to the fixed support, wherein the ejector is designed as a curved plate that gradually protrudes towards the second conveyor belt. The ejector is arranged in the adjacent area of the first conveyor belt and the second conveyor belt. In the region of the output end of the first conveyor, the containers which have been labelled (while the labels are still in the temporary first position) come into contact with a curved plate of the ejector which projects towards the second conveyor, so that the containers are pushed towards the second conveyor until they are pushed into the container receiving members of the second conveyor.
Advantageously, above said second conveyor belt there is provided a smoothing mechanism for the labels, comprising a smoothing plate. In particular, a smoothing mechanism is provided above the portion of the second conveyor belt adjacent to the first conveyor belt to prevent the labels from creasing.
Preferably, the labeling apparatus further comprises a feeding device for placing the non-standing containers one by one into the container receiving members of the first conveyor.
Preferably, a heat-shrinking oven is arranged downstream of the labeling device, wherein the second conveyor belt extends through the heat-shrinking oven.
The label sleeving equipment with any one of the variants realizes label sleeving through the following steps: placing the containers seriatim into container receiving members of the first conveyor; turning at least a portion of the first conveyor belt from a horizontal state to a vertical state about a conveying direction of the first conveyor belt while the first conveyor belt is circulating, so that the containers in the container receiving members are in an upright state while passing through a labeling station of a labeling device; labeling the container in the vertical state, and sleeving a label at the middle position of the container; inverting at least a portion of the first belt or chain back to a horizontal state; ejecting the labeled containers from the first conveyor container receiving members into the container receiving members of the second conveyor and applying the labels at the final positions of the containers; and conveying the complete set of target containers to a thermal shrinkage furnace for thermal shrinkage treatment.

Detailed Description
The following detailed description of embodiments of the utility model refers to the accompanying drawings. It is obvious that the described embodiments are only a part of the possible embodiments of the utility model, but the utility model is not limited thereto.
Fig. 1 shows a schematic illustration of a labeling device according to a preferred embodiment of the utility model. As shown in fig. 1, the label sleeving apparatus 100 mainly includes a feeding device 1, a conveying device 2, a label sleeving device 3, and a heat shrinking furnace 4. The loading device 1 is designed here as a lifting roller device for transporting containers, for example, filled containers in a stack, one by one onto the conveyor device 2. In particular into the container receiving members of the first conveyor belt 5 of the conveyor 2. As is clearly shown in fig. 1, the conveyor 2 comprises two endless belts, namely a first belt 5 and a second belt 6. The first conveyor belt 5 is used to receive the containers to be labeled from the loading device 1 and to convey them through the labeling station of the labeling device 3. After extending past the labeling device 3, the first conveyor belt 5 adjoins the second conveyor belt 6 at the output end. That is, the output end of the first conveyor belt 5 and the input end of the second conveyor belt 6 are arranged in parallel close to each other in the abutment region. In the adjoining area there is also provided a not shown ejector mechanism comprising a curved plate (not shown) protruding from the first conveyor belt 5 towards the second conveyor belt 6. The curved plate is fixed on a frame of the label sleeving equipment or other static devices through a fixing support. At the output end of the first conveyor 5, i.e. the abutment area, the containers that have been labelled (while the labels are still in the temporary first position) come into contact with the curved surface of the curved plate that projects towards the second conveyor, so that the containers are pushed towards the second conveyor 6 until they are pushed into the container receiving means of the second conveyor 6. It is obvious that the ejector mechanism can also be designed in other forms, such as a pneumatic or hydraulic ejector cylinder, an electric ejector rod, etc.
Although not shown in detail for the sake of clarity, the first conveyor belt 5 is also provided with a turning mechanism and a holding mechanism, the turning mechanism being designed to turn at least a part of the first conveyor belt 5 (via that part of the labeling device 3) around its direction of movement and to bring the containers in an upright state via the labeling station of the labeling device 3 via the holding mechanism. The labeling device 100 may be designed according to the prior art for labeling upright containers. When the label is being applied, the containers are held in an upright position by the U-shaped container receiving members and the holding mechanism of the first conveyor 5. That is, the compression members of the retention mechanism, such as compression rods or compression plates, compressively retain the containers in the container receiving slots. At this point, the label can only fit over the container in the portion above the pinch plate or pinch bar, as the pinch plate or pinch bar is pressed against the container body. The tilting mechanism can be designed as a guide surface that is arched in the lateral direction, on which the first conveyor belt 5 is guided, which extends over the labeling means 3 and is designed to be vertical at the same time as the labeling position of the labeling means. That is, the guide surface is designed as a curved surface that is curved and twisted, and that is first gradually inverted from the horizontal state to the vertical state, and then returns from the vertical state to the horizontal state. Since the first conveyor belt 5 is guided on the curved surface, it also changes according to the change of the curved surface. Other forms of flipping mechanisms, such as a motor-driven flipping toggle arrangement, are also contemplated. The retaining means may be arranged to press against the containers at least from the position where the first conveyor belt 5 starts to turn over.
After labeling is completed, the labeled containers are returned to a horizontal position. At this point, the label is in a temporary first position, covering only a portion of the container and possibly beyond the container. Here, the first position is not a specific one but all positions that have not reached the final position. The labelled containers are brought into contact with the ejector of the ejector mechanism at the end of the first conveyor belt 5, i.e. in the abutment region. As the ejector face of the ejector is gradually convex towards the second conveyor belt, the labeled containers are gradually ejected into the second conveyor belt 6 container receiving members. The second conveyor belt 6 is provided with a stop at the side facing away from the first conveyor belt. The stop stops the label that has passed beyond the container in the end position, while the lower end of the container advances, by the action of the pusher face or in the direction of the second conveyor belt 6, until the label reaches the final position on the container, thus finally completing the labeling. In order to avoid the labels from crumpling up during ejection, a smoothing mechanism, for example in the form of a smoothing plate, is provided above the portion of the second conveyor belt 6 located in the abutment region. The smoothing plate is slightly higher than the second conveyor belt 6 and is positioned right above the label sleeve containers on the second conveyor belt 6. That is, the flattening plate directly above prevents the label from wrinkling.
The containers after the completion of the labeling are conveyed further by a second conveyor 6 to a heat shrinking oven 4 located downstream. The heat shrinking oven 4 can be designed completely according to the prior art. The container after the label set is heated and shrunk in a heat shrinking furnace, so that the label is perfectly attached to the outer contour of the container. The containers subjected to heat shrinkage are conveyed to the subsequent station by the second conveyor 6. Such as blow drying or packaging stations.
Fig. 2 shows a side view of the labeling apparatus 100 shown in fig. 1. As shown in fig. 2, the charging device 1 comprises a hopper 7 and an elevator roller mechanism 8, wherein the elevator roller mechanism 8 is arranged inclined at an angle of approximately 30-60 ° with respect to the ground. The first conveyor belt 5 receives the containers to be labeled one by one from the lift roller mechanism 8 by the container receiving member. The container receiving member is designed as a U-shaped groove. It is obvious that other shapes, such as a C-shape or other shapes adapted to the outer shape of the container, are also possible. The first conveyor belt 5 extends through the labeling device 3. The label sleeving device 3 comprises a label feeding device 9, a control panel 10 and a label sleeving mechanism 11. The containers after the labeling are pushed against the second conveyor belt 6 downstream of the labeling device 3. The second conveyor belt 6 carries the label sleeving container to pass through a thermal contraction furnace 4 for shrinkage sizing. The loading unit 1 and the transport unit 2 are each driven by a motor and are each supported on the floor by a frame 12.
The utility model also comprises a method for labeling a container that is not easy to stand by means of the labeling device 100 according to the utility model. The method flow is briefly described as follows:
first, the operator puts the filled containers in batch into the hopper 7 of the loading device 1. The loading device 1 lifts the containers by means of a lifting roller mechanism 8 to the input end of the first conveyor belt 5. The first conveyor belt 5 receives the containers one by means of container receiving members arranged on the outside thereof and conveys the containers in the direction of the labeling device 3. During the transport, the first conveyor belt 5 together with the containers thereon is turned over from a horizontal position so that the containers are in a vertical position when they pass through the labeling station of the labeling device 3. After the labeling of the containers at the labeling station, the first conveyor belt 5 and the containers are again turned back to the horizontal position and the labeled containers (still in the intermediate state of the labeling, the labels being applied to a portion of the containers) are conveyed further to the output thereof. At this output end, i.e. in the region of the abutment of the first conveyor 5 and the second conveyor 6, the containers are pushed by the pushing mechanism into the container receiving members of the second conveyor 6. During the ejection, the label is also applied to the final position of the container, thus completing the labeling action. After this, the second conveyor 6 transports the complete set of target containers to the heat shrinking oven 4 for shrink-setting. Optionally, label smoothing may be performed in parallel during ejection to avoid possible label wrinkling. In addition, the shrink-molded containers are conveyed to a downstream blow-drying or packaging station for subsequent operations.
In general, in the solution of the utility model, the labeling process for containers that are not easy to stand is ingeniously realized by the turning over of the first conveyor belt and the pushing from the first conveyor belt to the second conveyor belt. The automation degree of the process of the container which is not easy to stand is greatly improved, and the production efficiency is improved.
