Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a feeding device that can feed a plate glass that is propped up in a horizontal state.

[Conventional technology]

In order to sequentially supply a large number of sheets of glass leaning against a pedestal, the pedestal is placed horizontally on a pedestal with a roller conveyor on the top surface, and then the undulating arm provided on the pedestal is rotated in the rising direction. After the glass plate on the pedestal is suctioned by the suction cup, the glass plate is unloaded onto the roller conveyor on the pedestal while rotating the arm in the falling direction.

Thereafter, a roller conveyor is operated to supply the plate glass to the front of the table, for example, to a glass cutting machine.

[Problems to be Solved by the Invention] Since a stand with a roller conveyor is installed close to the front of the glass cutting machine, there is a problem that the stand gets in the way during maintenance and inspection of the glass cutting machine.

Additionally, there was a problem in that the combination of the cutting machine and the stand required a large floor area.

[Means for solving problems]

In order to solve the above problems, this idea
A frame on which a large number of glass plates are propped up and moved forward intermittently at pitches equal to the wall thickness of the glass plates;
An arm is provided on both sides of the front of the glass plate so that the lower end is pivoted so that it can be rotated up and down, and the upper end of this arm is supported, and when the arm is raised, the conveying surface is parallel to the surface of the glass plate that is leaning against it. It consists of a roller conveyor with a drive function, and a suction cup placed at an appropriate position on the roller conveyor so as to move in and out of the conveyance surface.

[Effect]

This idea rotates the arm in the upright direction so that the roller conveyor is parallel to the surface of the glass sheet in the front row, and then moves the suction cup in the protruding direction to press the suction cup against the surface of the glass sheet.

After that, the inside of the suction cup is made to have a negative pressure and the glass plate in the front row is suctioned, and then the glass plate is removed from the pedestal while rotating the arm in the falling direction.

When the unloaded glass plate is in a horizontal state, the arm stops rotating in the falling direction, and then the suction cup is released and moved in the retracting direction while unloading the glass plate onto the roller conveyor, and the roller conveyor is driven. For example, the sheet glass is fed into a glass cutting machine.

〔Example〕

In the figure, reference numeral 1 denotes a pedestal on which a large number of glass plates A are propped up, and on both sides of the front of this pedestal 1,
A pair of left and right undulation arms 2, 2' whose lower ends are pivotally supported are provided.

The above-mentioned up-and-down rotation of the arms 2, 2' is achieved by rotatably connecting both ends of the cylinder 5 to both sides of the seat 3 and the lower part of the arms 2, 2' via pins 4. This is done by the contraction and expansion action of 5.

Furthermore, a plate glass A is placed on the upper end of the arms 2, 2' when the arms 2, 2' are raised.
A roller conveyor 6 with a drive function is provided so that its conveyance surface is parallel to the plate surface of the roller conveyor 6.

The above-mentioned roller conveyor 6 consists of two parallel guide shafts 7, 7' whose ends are fixed to the upper ends of both arms 2, 2' in the case shown in the figure, and two parallel guide shafts 7, 7'.
A plurality of rods 9 are arranged in parallel at a predetermined interval with a cylindrical portion 8 at the end thereof slidably fitted to 7'.
, a rotating shaft 10 supported on the upper surface of each bar 9 when laid down horizontally, and a roller 11 provided at a predetermined distance between both ends of the rotating shaft 10. The two rows of generation shafts 10 are driven by a drive device 12 consisting of a motor and a chain that extends between the output shaft of the motor and the sprocket of the rotating shaft 10 to send out the glass plate A in one direction of the pedestal 1. It may also be sent out in front of the gantry 1.

Furthermore, a suction cup 13 that moves in and out of the conveyance surface is provided at a suitable location on the roller conveyor 6.

The suction cup 13 moves in and out of the cylinder 14 by expanding and contracting the cylinder 14.

As shown in the figure, after loosening the fastener 15 and sliding the cylindrical body 8, the cylindrical body 8 is fixed to the guide shaft 7' by tightening the above-mentioned fastener 15. After sliding the supporting slider 17 of the cylinder 14 using a guide 16 consisting of a dovetail groove and a protrusion fitted into the dovetail groove, the slider 17 is secured to a predetermined position on the guide 16 using a tightening tool 18. By making it possible to fix the suction cup 13, the position of the suction cup 13 can be freely changed according to the size of the glass plate A.

Further, the above-mentioned gantry 1 is adapted to move forward intermittently at a pitch equal to the thickness of the above-mentioned glass plate A after taking out the glass plate A.

In the case shown in the figure, the intermittent advance described above is
The table 20 is expanded by the extension of the cylinder 19 whose both ends are connected to the slide table 20 provided above.
It is now done by sliding the

As shown in the figure, jacks 21 are arranged at both the front and rear corners of the table 20, and both ends of the plate-shaped body 23 are rotatably attached to the protruding and retracting shafts 22 of the jacks 21. By keeping the shaped body 23 in contact, the plate surface of the plate glass A can be accurately paralleled to the suction surface of the suction cup 13 while sliding the pedestal 1 on the table 20 by operating the jack 21 at a predetermined position.

In the figure, reference numeral 24 denotes a protruding member that protrudes on both sides of the bar 9, and a trochanter 25 pivotally supported by this protruding member 24 causes the plate glass A to slide during feeding. 26 is a support shaft of the arms 2, 2'.

Next, the method for supplying glass plates will be explained. First, the pedestal 1 on which a large number of glass plates A are propped up is placed on the table 20.

Next, due to the contraction of the cylinder 5, the arm 2,
After rotating 2' in the rising direction and stopping,
Each suction cup 13 is made to protrude by the expansion action of the cylinder 14, and the suction cup 13 is brought into contact with the plate surface of the glass plate A in the front row on the pedestal 1, and the inside of the suction cup 13 is sucked.

Thereafter, the suction cup 13 is pulled back a little by the contraction action of the cylinder 14, and the first glass plate is peeled off from the second glass plate.

Thereafter, the arms 2 and 2' are rotated in the falling direction (from the chain line position in FIG. 1 to the solid line position) by the extension action of the cylinder 5, and after stopping, the sheet glass A is placed on the roller conveyor 6 by the contraction action of the cylinder 14. At the same time as unloading, the suction of the suction cup 13 is released immediately before unloading.

Then, the drive device 12 starts operating, and the plate glass A on the roller conveyor 6 is sent to the next processing machine.

[Effects] As described above, according to the plate glass supply device according to the invention, an undulating arm is provided on the mounting base of the pedestal on which the plate glass is propped up, and the roller conveyor is attached to this arm, and the roller is retracted from the pedestal. The conveyor is equipped with a suction cup to remove the plate glass.
The arm is raised to pick up the glass plate on the pedestal, and then the arm is folded down so that the glass plate can be unloaded onto the arm's roller conveyor and fed to the next processing machine.

Therefore, it is not necessary to arrange a table having a roller conveyor on the upper surface in front of the processing machine.

In addition, since no stand is required, maintenance and inspection of the processing machine is easy, and a large installation space is not required.
