Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a light weight work arranging apparatus.
[0002]
[Prior art]
Conventionally, it consists of a gripping part that sucks up the workpiece temporarily from the work tray, a placement part that arranges the work from the gripping part, and a moving part that swaps the positions of the work tray and the placement part. A work arranging device having a function of arranging from one to the delivery unit is used. The workpiece is sucked up by a vacuum hole formed in the holding part. When the work is arranged from the gripping part to the transfer part, the vacuum suction is stopped, but a work stuck to the gripping part is generated even if the vacuum air of the gripping part is turned off due to static electricity or dirt. Therefore, until now, when the work is arranged from the gripping part to the delivery part, after the vacuum air is turned off, the compressed air is sent to the vacuum hole for a moment as “vacuum break” to force the work from the gripping part. Was taken off and arranged in the place where it was placed.
[0003]
[Problems to be solved by the invention]
The prior art has the following drawbacks. In order to arrange the workpieces in the delivery section by “vacuum break”, the workpiece needs to be heavy enough to stay on the top surface of the delivery section without being blown away by compressed air. Using the technology, after peeling off with compressed air, it will bounce off at the delivery part and the light weight work will be lost, or if the light weight work is a brittle material, the light weight work will be damaged by the impact when it hits the delivery part, There were problems in terms of quantity and quality.
[0004]
The present invention has been made in view of such a conventional problem, and an object of the present invention is to provide a light-weight workpiece arrangement device that can arrange light-weight workpieces without causing problems.
[0005]
[Means for Solving the Problems]
At least, the workpiece the workpiece and grip portion temporarily sucking from the work tray, and placed passing portion for arranging the workpiece from the gripping portion consists of the mobile unit to switch the position of the placing passing portion and said work tray, a series of operations the in lightweight framework sequences apparatus having a function of sequence into the place pass portion from said work tray,
The gripping part is provided with a suction nozzle for gripping the workpiece by vacuum force,
A vacuum hole for attracting and arranging the workpieces by vacuum force is provided in the delivery unit, and the workpiece gripped by the suction nozzle is replaced by the operation of exchanging the positions of the workpiece tray and the delivery unit. After being arranged at a predetermined position on the upper surface of the delivery unit, the vacuum force of the suction nozzle is turned off, and then the vacuum force of the delivery unit is turned on, whereby the work is attracted to the delivery unit and arranged. A light-weight work arrangement device is used.
[0006]
And lightweight framework sequences device provided with a vacuum air flow rate adjusting function in the vacuum air path of the placing passing portion and the grip portion.
[0007]
A light-weight work arrangement apparatus in which a vacuum pressure sensor is provided in a vacuum air path between the gripping part and the placing part.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a light weight work arranging apparatus which is considered to be most suitable of the present invention will be described with reference to FIGS. FIG. 1 is a schematic perspective view of a light weight work arranging apparatus according to the present invention, FIG. 2 is a top view of FIG. 1, and FIG. 3 is a front view of FIG. In these drawings, the direction in which the work is conveyed to the delivery part by the gripping part is the Y-axis direction, the direction in which the gripping part sucks up the work is the Z-axis direction, and the direction perpendicular to the Y-axis and the Z-axis is the X-axis direction. And
[0009]
First, the workpiece W is a very small plate material, and a preferable shape applied to the light-weight workpiece arrangement apparatus 10 of the present invention has a thickness of 0.5 mm or less, a long side of 15 mm or less, and a short side of 5 mm or less. is there.
[0010]
In FIG. 1 to FIG. 3, a suction nozzle 12 as a gripping part for sucking up a certain number of works W arranged on the work tray 11 in the Z-axis direction, a fixed block 13 for fastening the suction nozzle 12, and in the Z-axis direction. A facing cylinder 14 is arranged. In order to move the work guide 16 as a delivery part for receiving the work W to the lower side of the Z axis of the suction nozzle 12, the single axis robot 15 facing the Y axis direction as the moving part moves the work tray 11 and the work guide 16. It is placed on the upper surface in the Z-axis direction.
[0011]
Furthermore, in the present invention, the vacuum force can be adjusted by connecting the speed controller 17 to the vacuum air path of the work guide 16 and the suction nozzle 12.
[0012]
Further, by connecting a pressure sensor 18 to the vacuum air path between the work guide 16 and the suction nozzle 12, it is possible to detect a pressure abnormality during delivery.
[0013]
The suction nozzle 12 sucks and holds the work W from the work tray 11 through the provided vacuum hole. Thereafter, the cylinder 14 is controlled by a solenoid valve, and the work W is temporarily retracted from the work tray 11 upward in the Z-axis direction by pushing up the fixed block 13 in the Z-axis direction by the cylinder rod.
[0014]
Next, the 1-axis robot 15 moves the work tray 11 and the work guide 16 horizontally in the Y-axis direction under the control of the motor, and the work guide 16 is put on standby to receive the work W below the suction nozzle 12 in the Z-axis direction. .
[0015]
Next, by returning the cylinder rod of the cylinder 14 downward in the Z-axis direction by electromagnetic valve control, the fixed block 13 pushed up by the cylinder rod is moved downward in the Z-axis, and the workpiece W sucked up by the suction nozzle 12 is moved. The work guide 16 is lowered to a position 0.1 to 5 mm above the Z-axis direction. At this time, the height adjustment in the Z-axis direction is provided on the work guide 16 and is performed by an adjustment screw that abuts against the fixed block 13.
[0016]
Next, the vacuum air of the suction nozzle 12 is turned off in accordance with a preset timing, the vacuum air is turned on to the work guide 16, and the work W is sucked to the work guide 16. The work W that does not fall due to static electricity or dirt simply by returning to the atmospheric pressure by the vacuum air OFF of the suction nozzle 12 is configured to be forcibly dropped by being attracted by the vacuum air of the work guide 16 at this time.
[0017]
Next, the dropped work W is transferred to the next process, the suction nozzle 12 is retracted upward in the Z-axis direction, the work tray 11 and the work guide 16 are returned to the initial positions, and the work is repeated.
[0018]
【The invention's effect】
As described above, the light-weight work arranging apparatus according to the present invention includes at least a gripping part that temporarily sucks up the work W from the work tray 11, a placement part that arranges the work W from the gripping part, and the work tray 11. It is composed of a moving part that replaces the position of the transfer part, and can be arranged even with a light work W that cannot be handled by the prior art by the vacuum air of the transfer part. Further, by connecting the speed controller 17 to the vacuum air path between the work guide 16 and the suction nozzle 12, even a fragile work W can be handled softly, and further, it is possible to cope with the change of the work W. Further, by connecting the pressure sensor 18 to the vacuum air path of the work guide 16 and the suction nozzle 12, it is possible to detect the presence of the work W that is not delivered and its location. In addition, since it is possible to handle a non-light workpiece W which has been handled in the prior art, it is also an apparatus capable of producing a variety of products.
