Description

  The present invention relates to a back plate receiving apparatus.

  Conventionally, there is an apparatus shown in FIG. 4 for reversing the front and back of a plate material. The apparatus shown in FIG. 4 is arranged between the first conveying apparatus 1 and the second conveying apparatus 2, and includes a guide 4 that slides and conveys the plate material 3, and conveyance of the guide 4. And a fixed inclined plate 5 provided at the front and lower side of the direction. In this case, the guide 4 includes a first piece portion 4a inclined downward from the upstream side toward the downstream side, and a second piece portion 4b inclined downward from the lower end edge of the first piece portion 4a toward the upstream side. Prepare. And the fixed inclination board 5 is arrange | positioned substantially parallel with a predetermined space | interval with respect to the 2nd piece part 4b. The plate member 3 in this case is a back plate having a substantially meniscal cross section having a flat surface portion 3b and an arc surface portion 3a. The flat surface portion is called the back surface, and the circular arc surface portion is called the front surface.

  Next, the inversion operation using the apparatus shown in FIG. 4 will be described. The back plate 3 is transported from the first transport device 1 to this device with the flat surface portion 3b facing upward. In this apparatus, first, the first piece 4a of the guide 4 is slid. Then, after sliding on the first piece 4 a, it collides with the fixed inclined plate 5. As a result of this collision, the back plate 3 rotates clockwise around the collision portion and is reversed, and then guided by the fixed inclined plate 5 and the second piece 4b of the guide 4 so as to be the second transport device. Will drop to 2.

  In this method, in order to reverse the back plate 3 by a collision, the speed of the back plate 3 at the time of the collision needs to satisfy a predetermined condition. Since the plate 3 has different weight and frictional resistance when the size is different, it is very difficult to cause the plate 3 to collide with the fixed inclined plate 5 in an optimal state. Therefore, there is a problem that the probability that the plate 3 is inverted is low.

  When the plate material 3 collides with the fixed inclined plate 5, there is a problem that the plate material 3 is broken by the impact. Since such a broken plate material cannot be used as a product, the yield is reduced. In order to remove the cracked plate material, it is necessary to stop the sawing line, resulting in a decrease in productivity.

  Therefore, an apparatus for improving the conventional method as shown in FIG. 4 has been proposed (Patent Document 1). The device described in Patent Document 1 is shown in FIG. Similar to the apparatus shown in FIG. 4, this apparatus is also arranged between the first conveying apparatus 1 and the second conveying apparatus 2, and includes conveying means 10 for conveying the back plate 3, and the back plate 3. And an inverting unit 11 for inverting the.

  The transport means 10 is a conveyor that tilts downward from the first transport device 1 toward the second transport device 2. The reversing unit 11 includes a receiving member 13 and a folding member 14 projecting from the receiving member 13, and is rotatable about a shaft portion 15 provided at the lower portion of the receiving member 13. Further, the receiving member 13 of the reversing part 11 is provided with a returning means 16 for the reversing part. The return means 16 includes a support member 17 and a resilient member 18 attached to the support member 17.

  In this apparatus, the back plate 3 collides with the receiving member 13 of the reversing unit 11 by being conveyed as indicated by an arrow through the conveying means 10. By this collision, the back plate 3 presses the receiving member 13, and the reversing portion 11 rotates around the shaft portion 15 as indicated by a virtual line. At this time, the receiving member 13 of the reversing part 11 contacts the stopper 19 and its rotation is restricted.

Due to the rotation of the reversing unit 11, the back plate 3 received by the folding member 14 is reversed and supplied to the second transport device 2. When the reversing unit 11 is in an empty state without the back plate 3, the reversing unit 11 is restored to the state indicated by the solid line by the return means 16 and can receive the next back plate 3. It becomes. Thereafter, the above-described steps are repeated, and the back plate 3 from the first transfer device 1 can be sequentially reversed and transferred to the second transfer device 2.
JP 2006-150531 A

  In the back plate receiving device described in Patent Document 1, the reversing unit 11 rotates at the time of collision with the receiving member 13 of the reversing unit 11, and the rotation of the reversing unit 11 can also be received by the stopper 19 made of an elastic material. Therefore, the impact on the back plate 3 can surely be reduced. However, although the probability of reversal is higher than that of the apparatus shown in FIG. 4, the reversal of the back plate 3 uses the impact force from the back plate 3 to the reversal unit 11, and the probability is still high. I can't say that. Moreover, even if the impact is alleviated, the back plate 3 collides with the receiving member 13 of the reversing part 11, so that the back plate 3 may be damaged or the reversing part 11 may be damaged.

  In view of the above-described problems, the present invention provides a back plate receiving apparatus that is highly accurate in changing the posture so that the flat portion faces downward and can prevent the back plate from being damaged.
