Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a thin plate conveying device that automatically takes out one thin plate from a stack of thin plates such as printed wiring boards and supplies it to a predetermined position. be.

Conventional structure and its problems A conventional conveying device of this type is structured as shown in FIG. That is, the movable part 1 is capable of vertical and horizontal movement, and the suction cup 2 provided on the movable part 1 sucks up the topmost thin plate 4 of the stacked thin plate group 3, and the movement of the movable part 1 causes the thin plate 4 to be lifted up. was being conveyed to a predetermined supply position 4a. However, with this configuration, the suction cup 2 may suck up the thin plate 4 with two or more thin plates stuck together due to the static electricity generated between the thin plates, the vacuum state, and the fusion brush generated on the cut surface of each book board. There is.

In order to prevent this situation, conventionally, as shown in FIG. 2, the timing at which the suction cup 2 rises is shifted from side to side, and the thin plate 5 stuck to the thin plate 4 is released.
However, with this method, the thin plate 5 does not reliably separate from the thin plate 4, and there are problems in which the thin plate 5 separates while the thin plate 4 is being conveyed, or the thin plate 4 is conveyed while the thin plate 5 remains stuck to the thin plate 4. there were. Purpose of the Invention In view of the above-mentioned drawbacks, the present invention provides a method for removing thin sheet 1 from a group of stacked sheets.
To provide a thin plate conveying device that can reliably convey a sheet to a predetermined position.

Structure of the Invention In order to achieve the above object, the present invention provides a positioning part that fixes the thin plate sucked up by the movable part suction cup in the vertical direction, and the lower part of the thin plate fixed by the positioning part is fixed to the thin plate. A separating rod is provided which moves in parallel to the fixed thin plate by a pressing part and pushes the displaced part of the unnecessary thin plate downward.

With this configuration, one thin plate can be reliably taken out from a group of stacked thin plates and fed to a predetermined supply position.

DESCRIPTION OF EMBODIMENTS A thin plate conveying apparatus according to an embodiment of the present invention will be described below with reference to FIGS. 3 to 8.

As shown in the figure, a group of thin plates 7 is loaded inside the stocker 6, a movable part 8 moves vertically and horizontally, and a suction cup 9 provided below the movable part 8 holds the group of thin plates. 7 is conveyed from the top one. An L-shaped main body bracket 12 having a support groove 11 provided below the positioning part 10 and a positioning part 10 fixed above is attached to the outside of one side surface of the stocker 6 provided with the inclined surface 6a. . Note that the positioning portion 10 is in a state of protruding above the stocker 6. Further, a pressing portion 15 is slidably inserted into the support groove 11 and operated by a cylinder 4 horizontally fixed to an L-shaped cylinder bracket 13 attached to the lower surface of the main body bracket 12. The holding hole 15a at the center of the pressing part 15 has a positioning part 1.
A pin 16 that slides in a sliding groove 10a provided at 0 is vertically erected, and above the tip of the pressing part 15 there is a pin 16 that is thicker than the thickness of one of the thin plates to be conveyed between it and the lower surface of the positioning part 10. , the recess 15 is formed so that a gap thinner than the thickness of the two sheets is created.
b is provided. Then, on the upper surface of the positioning section 10,
A microswitch 17 is fixed, which a pin 16 comes into contact with when the pressing portion 15 slides. Above the other side of the stocker 6, a steel plate guide 20 to which an L-shaped cylinder bracket 19 is attached via a side plate 18 is provided with an inclined surface 20a facing inward of the stocker 6.

A cylinder bracket 19 is vertically fixed to a sear cylinder 22 that moves the separation rod 21 in the vertical direction. The operation of this embodiment will be described below with reference to FIGS. 4 to 8. As shown in FIG. 4, the suction cup 9 of the movable part 8 comes into contact with the top thin plate 23 of the group of thin plates 7 loaded inside the stocker 6.

Next, as shown in FIG.
When the thin plate 24 stuck to is pulled up, the thin plate 23 comes into contact with the lower surface of the positioning part 10, and the thin plate 23 is positioned in the vertical direction. Then, as shown in FIG.
5 is actuated by the cylinder 14 and the pressing part 15 presses against the thin plate 24 until the pin 16 actuates the microswitch 17.
Continue to press so that it deviates from the thin plate 23. At this time, the book board 23 is inserted into the recess 15b of the pressing part 15, so it remains stationary. Next, as shown in FIG. 7, the separating rod 21 is moved downward by the cylinder 22 to drop the thin plate 24 that has shifted from the thin plate 23. As shown in FIG. 8, the position of the dropped thin plate is regulated by the inclined surface 20a of the steel plate guide 20 and the inclined surface 6a of the stocker 6, and it rides on the upper surface of the stacked thin plate group 7. When the thin plate 24 is dropped, the movable part 8 moves horizontally and conveys the thin plate 23 to a predetermined supply position. In this way, by affixing it to the thin plate 23, shifting the book board 24 with the pressing part 15, and pushing it down with the separation lever 21,
Only one thin plate 23 can be reliably picked out and conveyed from the stacked thin plate group 7.

In addition, in the description of the above embodiment, the thin plate 2 attached to the thin plate 23 is
4, however, even if a plurality of thin plates are attached to the thin plate 23, this embodiment has the same effect.

Effects of the Invention As described above, the present invention provides a separating rod in which the pressing part presses the lowermost thin plate fixed by the positioning part and pushes down the displaced thin plate by the pressing part. One thin plate can be reliably taken out from a group of thin plates and transported to a predetermined supply position.
