Description

Transmission device with jacking mechanism and label sleeving equipment

Technical Field

The utility model belongs to the technical field of product packaging, and particularly relates to a transmission device with a jacking mechanism and label sleeving equipment.

Background

The heat shrinkable film label can shrink along the outer contour of the container after being heated, clings to the surface of the container, and is widely applied to many industries at present. In particular, in the case of food and beverage packaging and packaging of various consumer products, manufacturers often choose to wrap a heat shrinkable film label around the outer surface of the product. Some devices for automated labeling have also been disclosed in the prior art. However, these labeling devices usually only can cover the heat shrinkable film on the bottle body, and cannot or need a very complicated mechanism to cover the bottom of the bottle. However, for some products (such as shampoo, cosmetics, etc.), it is desirable that the label at least partially cover the bottom of the bottle for aesthetic or hygienic reasons.

For example by chinese utility model patent CN212606105U discloses a spacer formula cover mark package end device, including cover mark conveyor and carriage install between cover mark conveyor and the carriage and lift up the device, wherein lift up the device and include that driving motor, belt pulley, two sets of centre gripping conveyer belts pass through the centre gripping conveyer belt that driving motor and belt pulley drove both sides and move for the product through two sets of centre gripping conveyer belt supports can be transmitted to the link joint conveyer belt after by two sets of centre gripping conveyer belt centre gripping. That is, in the solution disclosed in CN212606105U, the container with the label is lifted by the lifting device and the chain-link conveyor belt, and then the container is placed on the chain-link conveyor belt with the fixed cushion block, thereby the bottom of the container is lifted and conveyed through the thermal shrinkage furnace for shrinkage and bottom-wrapped label wrapping is realized.

However, the mechanism for lifting the container in the prior art is complex in structure and expensive in cost, and the mechanism participating in the coordination action is too many, so that the overall efficiency is low and the error rate is high. Therefore, it is desirable to provide a novel conveying mechanism which can lift the bottom of the container and realize a bottom-wrapped sleeve label on a sleeve label production line with a simple structure.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a transmission device with a jacking mechanism and label sleeving equipment, which can solve one or more technical problems in the prior art.

According to one aspect of the utility model, the above object is achieved by a conveyor device with a lifting mechanism, comprising a slat conveyor, a drive mechanism and a machine frame, the slat conveyor comprising a slat conveyor formed by a plurality of links connected in series one behind the other, which is supported on the machine frame and can be operated continuously in a circulating manner under the drive of the drive mechanism, wherein at least a part of the links is designed as a first link which is provided with a through-opening in a supporting surface for supporting a container and to which the lifting mechanism is fastened on the side opposite the supporting surface, the lifting mechanism comprising a push rod and an at least partially flexible connecting piece which is fixedly connected to the first link on the one hand and which directly or indirectly supports the push rod on the other hand, wherein the lower end of the push rod is fixedly connected to a roller mechanism, the conveying device further comprises a fixedly arranged rolling support rail which is at least partially convex in the vertical direction and extends between the encircling chain conveyors in the movement direction of the chain conveyors, wherein the push rod is pushed upwards and protrudes out of the through hole from the support surface of the first chain conveyor when the roller of the roller mechanism contacts the convex section of the rolling support rail. The first link plate is a link plate in which a through-opening is formed and to which a lifting device is fastened, which link plate serves to support the container during operation.

Advantageously, at least one second link plate is connected between two adjacent first link plates. That is, the link plate conveyor also has a second link plate that does not include any through holes and functions only to connect adjacent first link plates. In principle, it is also possible to form the link plate conveyor belt solely by the first link plate without any second link plate. However, by adjusting the distance between the first link plates, which are to carry the products, by connecting the second link plates in between, it is advantageously possible to match the operating speed of the link plate conveyor to the feed speed of the loading mechanism.

In the solution according to the utility model, the lifting of the container in a given position is achieved in a purely mechanical manner by using a lifting mechanism in cooperation with a rolling bearing rail. Therefore, a complex detection mechanism and a driving mechanism are avoided, the reliability of the transmission device is greatly improved, and the cost is reduced.

Preferably, the jacking mechanism further comprises a spring element, one end of the spring element abuts against the first chain plate, and the other end of the spring element abuts against the lower end of the ejector rod or the roller mechanism. When the roller contacts the convex part of the rolling support rail, the ejector rod is jacked upwards, and the spring is compressed. When the roller leaves the convex part of the rolling supporting rail, the compressed spring enables the mandril to quickly reset to the retraction position below the supporting surface.

Advantageously, at least one fixing hole is further provided in the first link plate for fixing the connecting element of the lifting device.

Preferably, two fixing holes are provided on the first link plate symmetrically with respect to the through hole. The lifting means can be fixed to the first link plate, for example, by screwing or riveting.

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.

As shown in fig. 1, a link plate conveyor 1 is formed by connecting a plurality of link plates in series in this order. Here, the link plate conveyor includes two types of link plates, i.e., a first link plate 2 and a second link plate 3. The first chain plate 2 is used for carrying a labeling container, and a through hole 4 is preferably arranged in the center of the first chain plate 2, so that a top rod of a jacking mechanism can protrude out of a bearing surface 5 of the first chain plate 2 in a jacking state. Two second chain plates 3 are connected between the first chain plates 2, and the first chain plates 2 and the second chain plates 3 are connected in series to form a chain plate conveyor belt 1. In principle, any number of second chain plates can also be arranged between the first chain plates 2 or none at all. The second link plate 3 has the same structure as the first link plate 2 except that it does not have the through-hole 4 and the fixing hole 6. Fig. 1 also shows that two fastening holes 6 are provided symmetrically with respect to the through-opening 4. This is for illustration purposes only, and one or more than two fixing holes may be provided. These fixing holes may not be arranged symmetrically with respect to the through-hole 4. The embodiment shown is preferred. In addition, although the fixing hole is shown in fig. 1, the jacking mechanism may be fixed to the first link plate 2 by other means, such as welding or bonding, instead of the fixing hole.

Fig. 2 shows a possible embodiment of the lifting device 8. The jacking mechanism 8 is fixed to the side of the first link plate 2 opposite to the bearing surface 5. As shown in fig. 2, the jacking mechanism 8 includes a ram 9, and the ram 9 is fixedly connected to a bearing 10 at a lower end thereof. The roller 11 is rotatably supported on the bearing 10 by a shaft. The bearing 10 is supported by a connecting member 12. The connecting member 12 is designed to be flexibly and fixedly secured at the upper end at the fixing hole 6 of the first link plate 2 by screwing or riveting. The connecting element 12 is made for example of leather or fabric or other flexible material. That is, the ram 9 is floatingly supported by the connecting member 12. When the roller 11 comes into contact with the projecting convex section of the rolling contact rail, the carrier rod 9 is pushed upward and projects beyond the first link plate 2. Thereby lifting the containers arranged on the first link plate 2. Preferably, a spring element 13 is arranged around the carrier rod 9, which spring element 13 bears on the one hand against the first link plate 2 and on the other hand against a shoulder at the lower end of the carrier rod 9. It is also possible to abut the spring element 13 against the bearing housing. When the ram 9 is raised, the spring element 13 is compressed. When the roller 11 leaves the rolling support rail, the mandril 9 descends. At this time, the spring force of the spring element 13 accelerates the return of the carrier rod 9 to a position below the first link plate 2, so that the containers are smoothly transported into the subsequent station. Of course, the spring element 13 is not necessary here, since the ram will also return to below the bearing surface 5 after the roller 11 has left the rolling bearing rail under the influence of the weight of the container and ram itself. However, this process can be accelerated by the provision of the spring element 13 and jamming can be avoided.

Figure 3 shows the conveyor 15 installed in the heat-shrinking oven 14. The conveyor 15 comprises a link plate conveyor belt 1 formed by connecting a first link plate 2 and a second link plate 3 in series. The link belt 1 is supported on a frame 7 and can be driven by a drive mechanism, not shown, to run continuously in a circulating manner. In operation, the label container is supported on the support surface 5 of the first chain plate 2. The jack-up mechanism 8 fixed to the first link plate 2 moves together with the first link plate 2. Below the link belt 1, a roller bearing rail is provided, the top face of which is at a distance from the bottom face of the link belt 1 (i.e. the face opposite the top face of the roller bearing rail) which is less than the overall height of the lifting device 8 in the non-lifted state. Therefore, when the roller 11 of the lifting mechanism 8 rolls on the convex section of the rolling support rail, the lifting mechanism 8 is lifted upward as a whole and the push rod 9 protrudes outward through the through hole 4 of the first link plate 2, so that the label container supported on the support surface 5 of the first link plate 2 is lifted. After the bottom of the sleeve label container is lifted, the label slides downward by gravity or with the assistance of, for example, a brush or beater mechanism and beyond the bottom of the container. After being jacked, the sleeve label container remains in this jacked condition and is conveyed through the heat shrink oven 14. The label made of the heat shrinkable film is heat shrunk in the heat shrinking furnace 14 to be attached to the outer contour of the container, thereby realizing the coating of the bottom of the container. It is noted here that the coating of the bottom may be a partial coating or a complete coating.

As shown in fig. 3, the frame 7 extends through the cavity of the heat shrinking oven 14. The rolling support rails also extend at least from the entrance of the furnace chamber to the exit of the furnace chamber, in particular at least the raised sections of the rolling support rails extend from the entrance of the furnace chamber to the exit of the furnace chamber. That is, the rolling support rail may include a convex section and a non-convex section, which is not in contact with the roller 11 but merely functions to support and fix the entire rolling support rail. Preferably, a ramp-like or arc-like transition is provided between the non-protruding section and the protruding section, so that the link belt 1 runs smoothly. In the simplest case, the rolling bearing rail can, of course, have only a projecting part.

In order to stabilize the lifted containers, the conveying device also has a pressing belt, which is arranged parallel to the rolling bearing rails above the link conveyors 1 and moves synchronously with the link conveyors 1 in order to hold the lifted containers pressed between the pressing belt and the link conveyors 1 during the operation of the link conveyors 1. The raised containers are pressed by the pressing belt, so that the containers can be kept stable even when the chain-link conveyor runs at a high speed. Advantageously, the transmission device further comprises a photosensor in the form of a grating scale or encoder and a control device. The belt is synchronized with the link belt 1 by means of a photoelectric sensor in combination with a control device.

The utility model also relates to a label sleeving device which comprises a feeding mechanism, a label sleeving mechanism and a heat shrinkage furnace, wherein a conveying device with a jacking mechanism according to any embodiment of the utility model is further arranged in the heat shrinkage furnace. Here, the furnace body configurations of the feeding mechanism, the labeling mechanism and the heat shrinking furnace are well known in the art and will not be described herein.

In the solution of the present application, the lifting of the containers is achieved in a purely mechanical manner by fixing the lifting means 8 with the rollers 11 below the first link 2 and by providing the rolling bearing rails with the raised sections below the link conveyor 1. The scheme is safe and reliable, and has fewer mechanisms for realizing the scheme, thereby reducing the cost of the whole equipment and improving the efficiency and the reliability.
