Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a glass bottle transfer device, and particularly to a glass bottle transfer device that can move a group of glass bottles sent over a lehr net onto a bottle conveyor. This invention relates to a bottle transfer device.

[Conventional technology]

Devices for transferring glass bottles on an annealing furnace net onto a bottle conveyor are known (for example, in
60-144237). This type of conventional device is provided with a traveling carriage that can run on a guide frame installed between the lehr net and the bottle conveyor, and a lifting platform that can be raised and lowered is suspended below the traveling carriage. It consists of a bottle gripper that can be opened and closed on the underside of the lifting platform. After the elevator platform is lowered and the bottle grippers grip the openings of a group of glass bottles on the lehr net, the elevator platform is raised and the traveling cart is driven to transport the bottles onto the bottle conveyor.

Furthermore, in this configuration, a drive device for traveling is mounted on the traveling cart, and an opening/closing drive device for the bottle gripper is attached to the lifting platform.

[Problem that the invention seeks to solve]

By the way, this type of device needs to grasp multiple glass bottles in a horizontal row on the lehr net at once and transfer them onto the bottle conveyor at the same time, but in conventional devices, there are many bottle conveyors. When bottles are arranged in rows, there is a problem in that it is difficult to distribute and transfer bottles in multiple rows on each bottle conveyor in an orderly manner.

In addition, conventional devices are configured to always grip all glass bottles in a horizontal row.
If a glass bottle falls over on the lehr net and disrupts the horizontal alignment, the entire apparatus must be stopped, which reduces the efficiency of transfer.

In addition, since the above-mentioned drive device is attached to the traveling part of a traveling cart, the weight of the traveling part increases, making it impossible to increase the transfer speed. There was a problem in that the transfer speed could not be increased because it was carried out after the transfer.

In addition, if the transfer speed cannot be increased in this way, it becomes difficult to adjust the feeding speed of the lehr net, and especially when the glass bottles have large diameters, the gap between the bottles becomes clogged on the lehr net. As a result, there was a problem in that it was difficult to smoothly transfer these horizontal rows of glass bottles onto the bottle conveyor.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above-mentioned problems of the conventional technology, to make it possible to transfer a group of glass bottles on a lehr net to a bottle conveyor in an orderly manner in multiple rows, and to increase the transfer speed. An object of the present invention is to provide a glass bottle transfer device that can be configured.
