Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer device for glass articles, particularly for a large-sized cathode ray tube funnel,
The present invention relates to a carrier device suitable for transferring glass articles having a special shape.

[0002]

2. Description of the Related Art Generally, a glass article manufactured in a factory is subjected to various inspections before the packaging process. Therefore, the glass article is often used for inspection while being conveyed by the conveyor, but it may be necessary to transfer the glass article from the conveyor to another conveyor during the inspection.
Conventionally, such transfer is often performed manually, but in the case of a heavy glass article, it is a heavy burden.

Under these circumstances, various devices for transferring glass articles have been studied, and for example, an apparatus for chucking and transferring a part of a glass article has been put into practical use. For example, in the case of a funnel for a cathode ray tube, a device for chucking the nose part or the neck part, placing the chuck part on top, and suspending and transferring the device has been put into practical use.

[0004]

However, in a transfer device that chucks the nose part or neck part of the funnel for a cathode ray tube, the moment of inertia, which increases at the time of starting and stopping as the transfer speed increases, causes a moment of inertia. There is a problem that it concentrates on and is easily damaged. There is also a problem that the funnel for the cathode ray tube shakes during transfer, comes into contact with other equipment, and is easily damaged.

An object of the present invention is to provide a transfer device capable of transferring glass articles such as funnels for cathode ray tubes at high speed and stably, and also to measure dimensions during transfer. It is to provide a transfer device.

[0006]

The glass article transfer device of the present invention comprises two bases arranged at regular intervals.
Two rails mounted in parallel on each base so that they are located on the extension lines of each other, two movable carriages that can move along each rail, and an air cylinder attached to each movable carriage It is characterized by comprising a movable support plate and a plurality of glass receiving bars which are attached so as to connect the respective support plates and on which glass articles can be placed.

Another aspect of the glass article transfer device of the present invention is two bases arranged at a constant interval, and two bases are provided on each base so as to be located on the extension lines of each other. Rails mounted in parallel, two movable carriages that can move along each rail, a support plate that can be moved up and down by an air cylinder attached to each movable carriage, and mounting so that each support plate is connected It is characterized by comprising a plurality of glass receiving bars on which glass articles can be placed and a dimension measuring device arranged between each base.

[0008]

When the glass article transfer device of the present invention is used,
For example, when a glass article conveyed by a roller conveyor reaches above a plurality of glass receiving bars, the glass receiving bar is raised to pick up the glass article, and then the glass receiving bar is moved forward and downward to separate another glass receiving bar. It is possible to stably transfer to a roller conveyor.

Moreover, if a dimension measuring device is arranged between the bases, it is possible to measure the dimension of the glass article during the transfer. As a dimension measuring instrument to be used, a measuring instrument having a form that can be inserted into an automated line is suitable for measuring the outer circumference and unevenness of the joint of the funnel for a cathode ray tube, the center deviation of the yoke part, the center deviation of the neck tube and the inclination.
