Technical Field

The invention belongs to the technical field of automatic tube feeding machines of bottle-making machines, and particularly relates to a tube feeding device and a tube feeding method of an automatic tube feeding machine of a bottle-making machine.

Background

At present, a pipe supply device for an automatic pipe feeding machine of a bottle making machine mainly has the function of automatically replenishing a material pipe for a transfer pipe inserting mechanism of the automatic pipe feeding machine of the bottle making machine, and the related patent application conditions are as follows:

the applicant of the present invention applies application No. 201220075701.8, entitled "tube supply mechanism for automatic tube feeding device of bottle making machine" at 31/10/2012, and this patent disperses the tubes in the storage tube rack to generate extrusion force between the tubes toward the outlet of the tubes, and utilizes the balance adjuster to adjust the storage tube rack to automatically roll down the tubes arranged in the storage tube rack into the storage tube chamber formed by the conveying belt and the retainer plate. Although this technical scheme can effectively carry the material pipe to sending during the pipe hoist mechanism, this scheme still makes the structure of sending the pipe hoist mechanism of automatic top tube device complicated except that the pipe, the intubate time are got to the sending pipe hoist mechanism that has the automatic top tube machine of extension bottle-making, causes work efficiency to descend, very easily causes machinery or electrical apparatus trouble.

In order to provide a pipe supply device of an automatic pipe feeding machine of a bottle making machine, which has stable performance, accurate positioning and automatic pipe conveying, the applicant applies a utility model patent with application number of 201420530894.0 and invented name of "pipe supply mechanism of an automatic pipe feeding device of a bottle making machine" on 16 th 09.2014, and the patent adds a pipe lifting assembly at an output port of the pipe conveying machine on the basis of the original pipe supply mechanism, so that the pushing and lifting mechanism comprises a support, a pipe conveying machine assembled on the support and a pipe pushing and lifting assembly arranged at an output port of the pipe conveying machine. The material pipe lifting assembly can push and lift the material pipe to a pipe grabbing position of a mechanical claw of the transfer pipe inserting mechanism through the working matching among the driving motor, the two pairs of connecting rods, the rocker arm, the transmission shaft and the connecting piece. Although the mechanism can be effectively matched with a pipe supply mechanism of an automatic pipe feeding device of a bottle making machine, the material pipe required by the bottle making machine is stably and effectively conveyed in place. However, the mechanism adopts a transmission mode of the rocker arm and the connecting plate, so that the mechanism is easy to cause a jamming fault when the driving amplitude of the rocker arm is large, and has the defect of low driving and positioning precision.

In order to further provide a pushing and lifting mechanism of a pipe supplying device of an automatic pipe feeding machine of a bottle making machine, which has stable performance and high driving and positioning precision, the applicant applies a utility model patent with application number of 201420675743.4 and invented name of a material pipe pushing and lifting mechanism of a full-automatic pipe feeding machine on 11/13/2014, the material pipe pushing and lifting mechanism is a transmission mode of improving the transmission modes of an original rocker arm and a connecting plate into a transmission mode of a gear and a rack, so that the pushing and lifting mechanism has compact integral structure, flexible transmission and low failure rate. Although the mechanism can be effectively matched with a pipe supplying mechanism of an automatic pipe supplying device of a bottle making machine, the pipe supplying device and the pipe supplying method of the automatic pipe supplying device of the existing bottle making machine have the following defects:

firstly, the product quality of the glass product is influenced. In the prior art, the weight of the material pipes is utilized to act on the material pipes to automatically roll to an output position, so that extrusion force can be generated between the material pipes, and when the number of the material pipes is larger, the extrusion force between the material pipes is larger, so that friction is generated between the material pipes, particularly, friction force can be generated between the material pipes and a pipe storage frame and between the material pipes and pipe grooves of the conveying disc, the surfaces of the material pipes are easily scratched, and the quality of glass products is influenced.

And secondly, the production cost of enterprises is increased, and the production efficiency of the enterprises is reduced. In the process of rolling off the material pipes scattered in the prior art to the transfer disc, the material pipes can collide with each other and fall easily, so that the material pipes are broken and damaged, the material pipes are wasted, and the production cost of enterprises is increased. And for damaged and broken material pipes, operators are easily scratched in the manual removing process, and potential safety hazards exist. More importantly, in the process of removing the damaged material pipe, the machine needs to be stopped, the continuous work of the automatic pipe feeding machine and even the bottle making machine can be seriously influenced, and the production efficiency of enterprises is reduced.

And thirdly, only the material pipes with the same diameter can be transferred. In the prior art, the material pipe with a specific specification can only be transferred, even if the material pipe groove is adjusted according to the specification of the transferred material pipe and the balance adjuster is used for adapting to the transfer of the material pipes with different pipe diameters, the adjusting process is complicated, the labor force and the time cost are greatly increased, and certain limitation is realized during use. And the production requirements of glass products with various specifications cannot be met.
