2. Description of the Related Art Conventionally, this type of air conveying apparatus has been used for conveying a plate-like work having a flat surface. As an example, there is an air transfer device disclosed in Japanese Utility Model Laid-Open No. 41107728.

This air transfer device has a first hole on the transfer plate whose transfer direction is changed and which blows out compressed air inclined in the direction in which the work is transferred, and a new hole different in inclination angle from the first hole. Altering the conveying direction of a work by alternately opening second holes having an inclination angle in the conveying direction and controlling the supply amount of compressed air blown out from the first holes and the second holes of the conveying plate. Is characterized by.

[0004]

However, in the above-described air carrying device, the carrying direction is uniquely determined by the tilt angle of the second hole, and it cannot be changed to various directions unless the tilt angle of the second hole is changed. There is a drawback that. Further, although a large number of holes are formed in the vertical and horizontal directions, it is a national difficulty to uniformly control the amount of compressed air blown out from each hole, and in some cases, there is a possibility that a deviation occurs in the carrying direction and the work falls from the carrying plate. Further, this air carrying device has a limited direction changing function but no stopping function. Therefore, when the work is continuously conveyed, it is difficult to smoothly convey the work because the work is stagnant or the work is dropped.

Therefore, an object of the present invention is to advance the work,
An object of the present invention is to provide an air transfer device that can be smoothly moved by reversely moving or stopping and changing the transfer direction of any work.

Which is a plate-shaped member having a hollow portion 13 and which wraps and holds the disc portion 11b at the other end of the pipe 3 so that the pipe 3 can be swung in the direction perpendicular to the direction of the arrow A and the air vent from the hollow portion 13 A manifold plate 2 is provided on the surface corresponding to the recess 12a and has an opening for exposing 3b. The manifold plate 2 is connected to the transfer table 1 via a pipe 3. An XY moving mechanism 4 for moving over relatively flat against Le 1, and a pneumatic control device 5 for adjusting the air pressure of compressed air supplied to the cavity 13.

A well-known technique is used for the XY moving mechanism of the manifold plate 2, and the drive mechanism for rotating the feed screws 7a, 7b by the motors 6a, 6b to move the manifold plate 2 with the engaging nuts, and the manifold plate 2 And a guide mechanism configured by guides 8a and 8b for planarly restricting the movement of the. The XY drive mechanism 4 is operated to move the manifold plate 2 in the X direction or the Y direction with respect to the transport table, and the pipe 3 is tilted in any direction to set the moving direction of the work 10. The conveyance speed is adjusted by the pressure of compressed air.

Although not shown in the drawing on the transfer table 1, it is desirable to embed a sensor such as a CCD in order to recognize the position of the work 10 and always recognize the position of the work. The plate 2 is moved so that the outlet 3a is tilted in the correction direction. In addition, it is desirable that the inclination of the air outlet 3a can be adjusted within a range of at least 60 degrees. The diameter of the outlet 3a is 0.
A range of 1 to 0.5 mm is reasonable, and the pneumatic control device 5 allows adjustment in the range of 1 to 5 kg / mm ² .

In the above-described air transfer device, while recognizing with the sensor, it is possible to move forward and backward in one direction or stop and change the direction while controlling the inclination and air pressure of the pipe 3, but the position recognition and the inclination control of the pipe are frequently performed. Must be done. For this reason, there is a limit in increasing the transport speed. Therefore, the air transfer apparatus of this embodiment has a function of maintaining the work at the center of the transfer line.

That is, as shown in FIG. 3, the air carrying device 14 of FIG. 1 is arranged in three rows in the carrying direction to form an air carrying device having one carrying table 1a. And
The inclination of the pipe of the central transport table of the transport table 1a is such that the pipe is tilted in the workpiece transport direction or is set up vertically so that the workpiece is moved forward or backward and stopped in the transport direction. The work can be maintained at the center of the work transfer line by directing the inclination of the blowout direction to the center. Therefore, if the air delivery devices arranged in the center all have the air outlets in the same direction all at once, the work can be fed in that direction at a high speed or at a desired speed by adjusting the tilt angle or the air pressure.

When it is desired to completely stop the work,
The outlet of the carrying table at the position to be stopped may be made vertical, and the outlets of the carrying table around the carrying table may be inclined toward the center.
