DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate material supply mechanism, and more particularly to a plate material supply mechanism for sequentially transporting stacked thin plate materials one by one.

[0002]

2. Description of the Related Art Conventionally, in order to supply a plate of this type, an operator manually removes and transports a required number of plates from a top of a plate stacked on a table or the like, and supplies the plate to each device. I was However, this work imposes a burden on workers and is a major obstacle in improving work efficiency. A plate material supply device that solves such a problem is disclosed in Japanese Patent Application Laid-Open No. 2-117519.

FIGS. 3 and 4 show Japanese Patent Application Laid-Open No. 2-117519.
FIG. 1 is a perspective view and a partial view for explaining a plate material supply device disclosed in Japanese Unexamined Patent Application Publication No. H10-110,026. As shown in FIG. 3, this plate body supply device includes a lifter 11 that can place a plurality of suitably stacked plate bodies 9 and move up and down by one pitch according to the plate thickness.
An engaging claw formed by forming a notch 15 on the lower surface of the distal end of the rotating member 14 attached to the base member 13 of the engaging portion 12 engaging with one side edge 9b of the plate 9 shown in FIG. 16 and a pusher A17 and a pusher B18 for sending out the plate 9 to each device.

[0004] The operation of the plate material supply apparatus is such that the stacked plate materials 9 are placed on a lifter 11, and one side edge 9 b of the uppermost plate material 9 among these plate materials 9 and a pusher A 17.
After engaging the engaging claw 16 of the engaging portion 12 located at the tip end portion of the pusher B18, the pusher A17 and the pusher B18 are extended, and the engaging claw 16 is pushed forward to thereby make the uppermost plate material. 9 is sent to each device side. Then, after the pushers A17 and B18 are retracted to their original positions, the lifter 11 is raised by the thickness of one plate material 9, and the uppermost plate material 9 is sent out by the pushers A17 and pushers B18 in the same manner as described above. Such an operation was sequentially repeated to supply the plate material 9.

[0005]

However, in the above-mentioned conventional plate supply mechanism, the thickness of the thin plate is less than, for example, t = 1 mm due to the structure of the claw portion engaging with the plate. In this case, there is a problem that two claws are simultaneously engaged and supplied.

Further, when such thin plate members are stacked one upon another, the plate members are in close contact with each other, and the adhesion force is strong, and most of the pressing force is lost to the peeling force. as a result,
When trying to feed one sheet at a time, even if the depth of the claws is made shallower than the plate thickness and pressed by the claws, the area of the engaging part is small and the pressing force of the claws is insufficient, and the plate material to be fed and its If the lower plate does not separate from the lower plate, the claws may swing over the plate to be fed, causing a scratch on the surface of the plate.

In any case, there is a problem that the plate material cannot be stably and automatically conveyed and supplied one by one. Also,
The surface finish of this type of plate material can have a significant effect on quality. In such a case, when the plate material is extruded with a pusher, the upper and lower plate materials slide with each other, causing abrasion on the surface and causing a serious defect in quality. In particular, dust and the like easily adhere to the surface of such a plate material, and this abrasion frequently occurs.

SUMMARY OF THE INVENTION An object of the present invention is to provide a plate material supply apparatus which can reliably carry out and supply plate materials one by one without causing abrasion on the surface.

[0009]

A feature of the present invention is that a plurality of plate members are stacked and placed in a state where the plate members are inclined so as to be directed forward with respect to the direction in which they are horizontally conveyed, and the thickness of the plate members is reduced. A table lifter that can be raised at a corresponding pitch, and a rear end portion of the uppermost plate material loaded on the table lifter is pressed by an inclined surface at the tip to generate a lever action to lift the front end portion of the plate material and lift the plate material. A pusher that makes the plate material substantially horizontal, an ascending and descending sending-out roller that comes into contact with the rear end portion of the plate material and feeds the plate material in the transport direction, and the tip end portion is floated by the pusher and sent by the sending-out auxiliary roller. A brush roller, on which the plate material is placed and rotated to feed the plate material in the transport direction and densely surround the outer periphery, in which brushes are buried and air outlets are provided at regular intervals between the brushes; In the transport direction to rotate pinching the sheet with a brush roller which is supplying mechanism of the plate and a pressing roller for feeding the plate material.

[0010] It is preferable that a means is provided for blowing air between the plate material floated and sent in the transport direction and the plate material thereunder. Further, it is preferable that a sensor for detecting that the plate material, which is floated at the tip end by the pusher, becomes horizontal is provided.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIGS. 1 (a) and 1 (b) are views showing a plate material supply apparatus according to an embodiment of the present invention. As shown in FIG. 1, the plate material supply device is arranged so that a plurality of the plate materials 9 are stacked and placed in a slanted manner with respect to the forward direction of the plate material 9 in the feed direction (pass line), and corresponds to the thickness of the plate material 9. A table lifter 1 capable of jogging at a pitch, and a rear end of the uppermost plate 9 loaded on the table lifter 1 being pushed by an inclined surface 2 to be moved in the feed direction by leverage.
a pusher 3 that floats the leading end of the sheet material 9a, a sending-out auxiliary roller 5 that descends, contacts the rear end of the sheet material 9a, rotates to send the sheet material 9a in the transport direction, and the tip of the plate material 9a whose other end is lifted and sent out. The plate member 9a whose tip is lifted by air blowing from an air outlet interposed between the brushes 4a, which is received densely around the outer periphery and which is interposed between the outer peripheral brushes 4a, and the plate member 9 therebelow. A brush roller 4 that rotates while pulling apart and feeds the plate material 9a;
A pressing roller 6 is provided to rotate the plate material 9a placed on the brush roller 4 and to convey the plate material 9a in the direction of the arrow.

It is desirable to provide an air blowing pipe 8 for blowing air between the plate member 9a and the plate member 9 therebelow. By providing this air blowing pipe 8, the plate material 9
Dirt and foreign matter on the surface of the substrate a and the surface of the plate member 9 thereunder are blown away, and abrasion does not occur on the surface during subsequent transportation. In addition, this air blowing
There is an advantage that it effectively acts to separate the plate material 9a from the plate material 9 thereunder.

Further, it is desirable to provide an upper surface detection sensor 7 for checking whether or not the tip end of the plate material 9a is lifted by the pusher 3 and the plate material 9a has reached a horizontal position. By providing the upper surface detection sensor 7, the sequence operation is smoothly controlled. That is, the plate member 9a serves as an interlock as to whether or not the front end portion of the plate material 9a has reliably laid on the brush roller 4.

FIG. 2 is an enlarged sectional view showing the brush roller of FIG. As shown in FIG. 2, the brush roller includes a main body 10 which is an air pipe having air blowing holes 4b formed at equal intervals on the outer periphery, and a brush 4a densely embedded in the outer periphery. . The brush 4a has a function of wiping foreign matter on the back surface of the plate material 9a. When the brush 4a is discharged and transferred to a subsequent conveyor, the brush material 4a is removed by the foreign material interposed between the sliding surface of the transport conveyor and the plate material 9a. To prevent abrasion on the surface. Further, the air from the air blowing hole 4b is supplied to the plate material 9a to be sent.
The plate 9a which is fed while assisting the separation between the plate 4a and the plate under the plate 4a makes the contact force with the brush 4a constant and the plate 9a
It has a role to maintain the level of.

Next, the operation of the sheet supply apparatus of FIG. 1 will be described. First, as shown in FIG. 1A, an appropriate number of plate members 9 are stacked and placed on the table lifter 1. And
The pusher 3 is advanced, and the rear end of the uppermost plate 9 a is pushed by the inclined surface 2. Thus, as shown in FIG. 1B, the tip of the plate 9 a is lifted by the lever action, and the plate 9 a is separated from the brush roller 4 by the air blowing force and becomes horizontal.

Next, the upper surface detection sensor 7 detects that the plate material 9a is horizontal, and air is blown out from the air blowing pipe 8 to blow off dust and foreign matter on the back surface of the plate material 9a and the surface of the plate material 9 therebelow. At the same time, the sending-out auxiliary roller 5 descends, rotates in contact with the surface of the rear end of the plate 9a, and feeds the plate 9a in the transport direction. Board material 9a sent
Is mounted on the brush roller 4 at its tip. Then, the plate material 9 a is fed by the rotation of the brush roller 4, and is sandwiched between the pressing roller 6 and the brush roller 4. And
The plate material 9a is further fed in the transport direction by the rotation of the pressing roller 6 and the brush roller 4. And the plate material 9a
Of the sheet material 9a is separated from the feeding auxiliary roller 5
The plate material is transferred to the conveyor.

Then, the sending-out auxiliary roller 5 rises and returns to the original plate, the table lifter 1 rises by the thickness of the plate 9, and performs the above operation to feed the next plate 9.
By detecting the presence or absence of the plate member 9a by the upper surface detection sensor 7, the plate member 9a and the plate member 9 thereunder can be easily separated by the blowing force of the air from the air outlet of the brush roller 4, so that the conventional long plate member is used. There is no need to provide a simple pusher or the like, and it is sufficient to provide only a roller feeding mechanism that requires a relatively small conveying force for feeding the plate material 9a, and there is an advantage that the apparatus can be made smaller.

[0019]

As described above, according to the present invention, the rear end of the uppermost plate, which is stacked and placed so as to descend in the feed direction, is pushed, and the leading end of the plate is leveraged. The plate material to be fed and the plate material thereunder can be easily separated by providing means for lifting the plate material to level the plate material and an auxiliary roller for feeding the plate material in a horizontal state to a roller feed mechanism, thereby enabling roller feeding. Since the separated plate members can be fed to the mechanism one by one, there is an effect that the automatic supply can be stably and efficiently performed to each device.

Further, when the leading end of the plate material to be fed is lifted, air is blown from right and left directions perpendicular to the plane of the plate material supply direction, so that abrasion due to conveyance and abrasion due to contact between the plate materials can be prevented. There is an effect that the yield of quality can be improved.
