[0023] In the existing sleeve labeling pipeline, the containers to be sleeved usually need to be kept standing or upright during the conveying process and the sleeving process. For some containers that are not easy to stand, they are prone to overturning or position deviation during the conveying and sleeving process. There are some solutions in the prior art for sleeving the two-section symmetrical containers that are not easy to stand, but there is no good solution for the asymmetrical containers without an intermediate clamping part. Therefore, the purpose of the utility model is to provide a standing auxiliary device for containers and a sleeve labeling equipment, which can ensure that the containers that are not easy to stand keep standing at least in the sleeving position, or even during the entire conveying process, so as to ensure that the containers are sleeved in the best posture, thereby ensuring the accuracy and speed of sleeving.

[0024] Figure 1 A schematic view of a container conveying pipeline provided with a plurality of standing auxiliary devices for containers is shown. For the sake of simplicity, only a module 1 schematically represents the conveying device including a conveying chain or belt and a support and the necessary adjustment mechanism in Figure 1 In the conveying direction of the containers, the conveying chain or belt conveys the containers in turn through a sleeve labeling mechanism and a heat shrinkage furnace, which are not shown here. According to the design of the existing sleeve labeling equipment, it is required to ensure that the containers stand or stand upright in the sleeve labeling mechanism.

[0025] As Figure 1 shown, a plurality of standing auxiliary devices 2 for containers are provided on the conveying belt or chain of the conveying device. Each standing auxiliary device 2 here includes three support pieces 3 and is fixed to the conveying belt or chain by means of bolts. The support pieces 3 are designed to be elastic and respectively open upward from below. These standing auxiliary devices 2 are preferably arranged in turn on the conveying chain or belt at equal intervals. When the conveying device is running, one container to be sleeved is placed in each standing auxiliary device 2. In the standing auxiliary device 2, the top of the container to be sleeved faces the conveying belt or chain, and the bottom faces upward, and the whole is in an inverted state. In the sleeve labeling position, the label is sleeved from the cylindrical bottom of the container and is advantageously held on the peripheral surface of the container by the support pieces 3 of the standing auxiliary device 2. Of course, the container to be sleeved can also be kept standing in the standing auxiliary device 2, depending on which posture is more convenient for sleeving.

[0026] Figure 2 A perspective view of the standing auxiliary device 2 is shown. By Figure 2It can be seen that the standing aid 2 has a base 4, a mounting plate 5 and three support pieces 3. However, the standing aid 2 can comprise more support pieces 3, for example four or five support pieces. Here, the base 4 and the mounting plate 5 are designed as circles of the same diameter. However, it is obvious that the base 4 and the mounting plate 5 can be designed in other suitable shapes. On the mounting plate 5 and the base 4 at least one corresponding screw hole 6 is provided, through which a screw for fixing the mounting plate 5 relative to the base 4 is passed. In the middle of the base 4 and the mounting plate 5 a central through hole is formed. In the central through hole a height-adjustable boss 7 is arranged, which projects from the base and the mounting plate in the direction towards the container and forms a support for the container. The base 4 has on the side facing away from the container a support flange 8 surrounding the central through hole, which is supported on a conveyor belt or a conveyor chain. In the centre of the boss 7 a through hole 9 is provided. A fixing bolt is passed through the through hole for fixedly connecting the standing aid 2 with the conveyor belt or the conveyor chain.

That is, the receiving holes of the same group of receiving holes are distributed on a circle of the same diameter. The receiving holes of different groups of receiving holes are at different distances from the centre of the base. Thus, different sizes of containers can be adapted to by arranging the support pieces 3 in different groups of receiving holes 10. It is advantageous if each group of receiving holes comprises three receiving holes which are distributed uniformly in the circumferential direction around the centre of the base. Three support pieces 3 which are arranged at an angle of 120° to each other enable a good stability of the container.

[0028] In Figure 2 In the shown solution the support pieces 3 have a vertical portion and an outward portion, wherein the vertical portion projects vertically upwards from the mounting plate and the outward portion is connected to the vertical portion and projects obliquely outwards relative to the vertical portion. However, it is also preferred that the support pieces 3 are designed as arcs and project gradually outwards upwards from the mounting plate.

By Figure 3It can be seen that the container 11 is clamped at the circumference by the support sheet 3 and thus can be held in a standing or upright position. In addition, the container 11 is supported at one end by the boss 7. The boss 7 is designed here to be height-adjustable and has a cylindrical overall profile. An internal thread is designed in the central through-hole of the base 4. An external thread is designed on the outer circumference of the boss 7, which is screwed into the central through-hole designed as a threaded hole and thus enables the height of the boss protruding from the base or mounting plate to be adjusted by rotation of the boss 7 relative to the base 4. However, the boss can also be designed in other forms, for example as a partially truncated cylinder. It is also conceivable to provide a scale on the end side protruding from the boss 7, thereby facilitating precise adjustment. The boss itself has a through-hole 9, which is designed here as a stepped hole. The standing aid 2 is passed through this through-hole 9 and its bolt head rests against the step of the through-hole 9. The base 4 has a support flange 8 on the side facing away from the container 11, which surrounds the central through-hole. The support flange 8 is supported on a conveyor belt or conveyor chain.
