Is tiltably mounted. Then, on the left side of the cart 26 of the dispensing cart C3, the chain 31
(See FIG. 7 (B)) are connected and driven by the same drive system as that of the loading carriage C1. This structure is the same for the dispensing cart C4. Although the basic configuration of the recovery carriage C5 is the same as that described above, the drive chain is connected to any one location such as the lower end of the carriage 26 because it travels on the recovery lane 9 with only one drive. Good. The push-up device 35, which is a mechanism for tilting the swing top plate 31, has a discharging station S7 and a collecting station S8.
It will be described later in detail.

10 to 11 are a plan view and a sectional view of the discharging station S7. Turntable 7
Is a turntable having a known structure, and turns in both directions indicated by arrows a and b. Further, a carry-out conveyor 8 is installed on the upper surface thereof. The carry-out conveyor 8 is composed of two chain conveyors 8a and 8b, and is driven by a motor (not shown). The end portions of the transport lanes 5 and 6 are discharge positions for discharging the residual rolls to the discharge conveyor 8, and a push-up device 35 for tilting the top plate 31 of the carry-in carriages C3 and C4 is installed at this discharge position.

The push-up device 35 comprises a cylinder 36 and a push rod 37 connected to its piston rod. When the cylinder 36 is extended, the swing top plate 31 is pushed up from a horizontal position shown by an imaginary line to an inclined position shown by a solid line. The remaining roll that has been conveyed can be sent onto the discharge conveyor 8. Then, the remaining roll is conveyed to the center of the turntable 7 by the discharge conveyor 8 and, at the same time, the turntable 7 is turned 90 ° in the arrow a direction or the arrow b direction so that the remaining roll can be discharged to the recovery lane 9.

Next, the recovery device will be described with reference to FIG. On the recovery lane 9, a recovery carriage C5 is designed to travel back and forth, and a swing top plate 31 of the recovery carriage C5.
Has the same structure as the dispensing carts C3 and C4. And
A push-up device 35 is installed on the side opposite to the recovery pit 10 at the end of the recovery lane 9. Further, a fixed stopper 38 is installed on the side of the recovery lane 9 corresponding to each turntable 7 on the side opposite the table so that the residual roll r sent from the discharge conveyor 8 does not get over the recovery carriage C5. Collection cart C that received the remaining roll r
5 travels in the recovery lane 9 and when it reaches the front of the recovery pit 10, it stops there, and then the swing top plate 31 is tilted by the push rod 37 of the thrust device 35, and the remaining roll r is paid out to the recovery pit 10. .

Next, the operation of the feeding / discharging device A having the above structure will be described. In FIG. 13, assuming that the mill roll R1 loaded on the left roll support arm RA of the mill roll stand MS is being used, the new roll R2 mounted on the right roll support arm RA is waiting, Further, new rolls R3, R4 loaded on the loading carriages C1, C2
And the new roll R5 at the receiving station S1 is also waiting. Therefore, four new rolls are on standby, and two new rolls R3 and R4 among them are ready to be loaded immediately by one-way traveling of the loading carriages C1 and C2. Therefore, even if rolls are frequently changed in high-mix low-lot production, new rolls will not be delayed in supply.

Next, considering the case where the roll R1 is unloaded and the new roll is used, it goes without saying that one of the new rolls R2 loaded in the mill roll stand MS can be immediately used, but the unrolled remaining roll r1. Since it can be quickly discharged from the machine, there is an advantage that there is no delay in the supply of the next new roll R3. That is, the remaining roll r1 is immediately sent to the discharge station S7 by the delivery cart C3,
From there, it is discharged through the turntable 7 and the recovery lane 9 as described above, but this route is a separate system from the supply route. Therefore, at the same time when the delivery cart C3 receives the remaining roll r1 and starts traveling, the loading cart C1 loaded with the new roll R3 can start traveling. The same applies to the second transportation lane 6 side. For the above reason, according to the feeding / discharging device A of the present embodiment, there is no delay in the supply of the new roll, and no unnecessary waiting time occurs on the corrugator side.

Next, the supply and discharge situation of the new and old rolls R and r in the entire corrugator will be described with reference to FIG. 1. Since the three mill roll stands MS are individually provided with the supply and discharge devices A, the above-mentioned new and old rolls are provided. The feeding / discharging operation is performed for each mill roll stand MS. In this case, as can be seen from FIG. 1, the supply of the new roll is shown by a solid arrow and the discharge of the remaining roll is shown by a dotted arrow.
Feeding is a one-way movement on one side of the machine,
Ejection is a one-way movement on the other side of the machine and does not interfere with each other. Therefore, according to this embodiment, the supply and discharge of the old and new rolls can be performed quickly and smoothly. In addition, since the transfer to each dolly can be performed mechanically, the labor-saving effect is high.

[0030]

According to the present invention, it is possible to eliminate the waiting time on the machine side and efficiently perform the production of small lots of a wide variety of products , and at the same time , the labor is greatly saved and the supply and discharge of the mill roll with a low equipment cost. Facilities can be provided.
