Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paperboard feeding apparatus for automatically feeding paperboard such as corrugated paper and cardboard to a box making machine, a printing machine and the like.

[0002]

2. Description of the Related Art A device for stacking and feeding paperboard, such as corrugated paperboard, cut into a predetermined size and stacked on a hopper for the purpose of printing or making a box is already disclosed in Japanese Patent Laid-Open No. No. 48664, Japanese Patent Publication No. 52-27898
Gazette, Japanese Patent Application Laid-Open No. 54-149176, and Shokai 61
No. 15940 is known. These devices sequentially feed paperboard in a state of being folded on a belt conveyor.

In a conventional storage conveyor in which the paperboard is dropped from the carry-in conveyor onto the carry-out conveyor in order to align the paperboard and change the direction in which the paperboard is folded, the paperboard is greatly inclined forward (turning forward) on the carry-in conveyor. , The subsequent paperboard falls further forward and tilts, and the paperboard rises on the carry-out conveyor, causing trouble.
For this reason, in the past, unless a certain number of leading paperboards were manually aligned and stacked on a carry-out conveyor, the succeeding paperboards could not be successfully stacked, and this required a lot of trouble.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a paperboard supply apparatus which improves the above and does not cause trouble even without human intervention.

[0005]

For this purpose, a paperboard feeding apparatus according to the present invention comprises a carry-in conveyor for moving a paperboard in a state of being folded on a conveyor belt, and a gate board facing the conveyor belt. In a state in which the paperboard is folded by receiving the paperboard dropped from the front edge of the carry-in conveyor by movement and flowing out the paperboard from the gap between the gate plate and the conveyor belt. A paperboard supply device to be moved further,
A flap capable of temporarily supporting the front edge of the paperboard that falls in a state inclined forward from the front edge of the carry-in conveyor at the lower edge of the gate plate during the fall thereof is provided so as to be able to stand up and down freely. . Further, the present invention is characterized in that, in the paperboard supply device, the gate plate is provided so as to be able to adjust a set height, and the gate plate is provided so as to be able to adjust a set position in a longitudinal direction of the carry-out conveyor. Further, the present invention is characterized in that in the above-mentioned paperboard supply apparatus, a pusher is provided below the front edge of the carry-in conveyor to press and align the paperboard dropped on the carry-out conveyor in the gate plate direction.

[0006]

Embodiments of the present invention will now be described with reference to the drawings. 1 and 2 show the entire paperboard supply apparatus according to the present invention. In the figure, reference numeral 1 denotes a machine provided with a carry-in conveyor 2, and the carry-in conveyor 2 is a belt conveyor composed of four endless belt-shaped conveyor belts 3a to 3d, the base end of which is located on the machine 1 The edge is pivotally supported by a bearing 4 with a bearing 4. Reference numeral 5 denotes a drive motor for driving the carry-in conveyor 2. Reference numeral 6 denotes a turning frame pivotally supported by a bearing 7 provided at the rear upper edge of the machine base 1. The turning frame 6 comprises a cylinder 8
1 is tilted with the bearing 7 as a fulcrum,
From the vertical upright state as shown by the broken line in FIG. Two tracks 9 are provided in the revolving frame 6, and the paperboard 10 is moved from the revolving frame 6 into the conveyor 2 by driving the tracks.
It is configured so that it can be transported in a state of being folded up. Although the configuration of this portion has conventionally been various, it is not directly related to the present invention, so the detailed description is omitted.

Reference numeral 11 denotes an unloading conveyor fixedly mounted on the machine base 1 so that the base end 12 is located below the distal end of the unloading conveyor 2, and 13a to 13d denote four endless conveyors constituting the unloading conveyor. A belt-shaped transport belt, 14 is the unloading conveyor 1
1 is a driving motor. 15 is a gate-type support frame 16
Is a gate plate supported so as to straddle the conveyor belts 13a to 13d. The gate-type support frame 16 has rail bases 17 at both ends of which are provided on both sides of the unloading conveyor 11.
It is slidably supported on the upper side, and is provided so as to be movable along the longitudinal direction of the carry-out conveyor by pulling a motor by an endless chain 19. In this way, the gate plate 15 is provided so that the set position can be adjusted in the longitudinal direction of the carry-out conveyor 11.

As shown in FIGS. 3 to 5, a pair of support plates 20 are fixed to the gate-type support frame 16, and guide shoes 21 provided on the support plate 20 are attached to both side edges of the gate plate 15. The gate plate 15 is supported so as to be vertically movable by matching the guide rail 22 provided. Reference numeral 23 denotes a motor provided for moving the gate plate 15 up and down. The rotation of the motor is transmitted to a transmission shaft 25 via a transmission chain 24, and a gear 26 fixed to the transmission shaft 25 is connected to the gate plate 1 by a gear.
5 is engaged with a rack 27 fixed to the rear surface. Thus, the gate plate 15 is provided so that the set height can be adjusted.

A bearing 30 is provided at the lower edge of the gate plate 15 to rotatably support the flap 31, and a lever 32 and a cylinder 3 projecting from the back of the flap 31.
3 via a pin 34, and the cylinder 3
The flap 31 is provided so as to be able to stand up and down by extending and retracting the flap 3.

Reference numeral 35 denotes a pusher provided below the front edge of the carry-in conveyor 2 to push and align the paperboard forward, and 36 denotes a cylinder for operating the pusher forward and backward.

In the paperboard feeding apparatus configured as described above, before the leading one of the paperboards 20 folded and transported by the carry-in conveyor 2 falls from the front edge of the carry-in conveyor 2, the flap 31 is moved to the position shown in FIG. As shown by a solid line in FIG.
The front edge of the paperboard 20, which falls in a forwardly inclined state from the front edge of the paperboard 20, can be temporarily supported by the flap 31 during the fall. For this reason, when the paperboard 20 is appropriately stacked on the flap 31, the cylinder 33 is contracted to make the flap 31 drip as shown in FIG. 6 so that the paperboard 20 is conveyed to the base end of the unloading conveyor 11. Accepted on belt. Then, the paperboard 20 received on the transport belt of the unloading conveyor 11 is gradually folded in a state of being folded through the gap g between the lower edge of the flap 31 and the transport belt by driving the transport belt. , And are successively sent out to a printing machine or a box making machine in an aligned state opposite to the case where the folding direction is on the carry-in conveyor 2.

The pusher 35 is connected to the carry-out conveyor 11.
The gate board 15 moves forward and backward in the direction of the flap 31 in order to press and align the plurality of paperboards 20 dropped on the transport belt at the base end of the gate board 15 in a straight stacked state.

Since the gap g can be adjusted by providing the gate plate 15 so that the set height can be adjusted, the folded state of the paperboard fed onto the carry-out conveyor 11 can be freely adjusted. In addition, since the gate plate 15 is provided so as to be able to adjust the set position in the longitudinal direction of the carry-out conveyor 11, setting according to the size of the paperboard becomes possible.

[0014]

As described above, the paperboard supply apparatus of the present invention is
If the flap is in the upright state, even if the leading paperboard falls forward from the front edge of the carry-in conveyor, it can be temporarily supported during the fall, so that the paperboard stands up on the carry-out conveyor. Since subsequent paperboards can be stacked without fail, there is a beneficial effect of eliminating the risk of causing trouble without requiring human intervention.
