[0005]

The apparatus shown in FIGS. 1 and 2 presses and discharges three pressed plates together, so that they can be efficiently pressed and discharged. However, when the number of stages of the multi-stage press is large, the take-out time of the plate to be pressed becomes longer than the press time of the multi-stage press, and the take-out time of the plate to be pressed limits the number of sheets manufactured per unit time. Therefore, it is required that the pressed plate be discharged from the unloader shelf more quickly.

The time required to discharge the plate to be pressed from the unloader shelf can be reduced by increasing the speed of the unloading conveyor. However, when the speed of the unloading conveyor is increased, there is a disadvantage that the posture of the plate to be pressed discharged from the unloader shelf shifts, and the plate cannot be transferred to an accurate position. For this reason, the transfer speed of the unloading conveyor is limited and cannot be so high.

The present invention has a unique structure and has been developed for the purpose of quickly discharging a plate to be pressed from a multi-stage unloader shelf.

[0008]

The multi-stage press take-out apparatus according to the present invention has the following arrangement to achieve the above object. The unloading device is the press plate 2 of the adjacent multi-stage press 1
And a multi-stage unloader shelf 4 from which a plurality of pressed plates 3 are transferred. Further, the take-out device of the present invention
The unloader shelf 4 is provided with a stepped portion 4B that is formed low on the discharge side of the plate 3 to be pressed. Further, in order to transfer the pressed plate 3 to the step portion 4B, the unloader shelf 4
Is inclined downward toward the step portion 4B. Pressed plate 3 supplied to unloader shelf 4 from press plate 2
Is advanced on the unloader shelf 4 inclined downward and is stacked on the step portion 4B. The overall width of the stacked pressed plates 3 is reduced. For example, when three pressed plates 3 are stacked, the width becomes 1/3. Pressed plate 3 with narrow width
Is transported in the width direction and is quickly discharged.

Embodiments of the present invention will be described below with reference to the drawings. However, the embodiments described below exemplify a multi-stage press take-out device for embodying the technical idea of the present invention, and the present invention does not specify the multi-stage press take-out device as follows.

Further, in this specification, in order to make it easier to understand the claims, the numbers corresponding to the members shown in the embodiments will be referred to as “claims” and “ In the column of “means”. However, the members described in the claims are not limited to the members of the embodiments.

FIGS. 3 and 4 are a side view and a plan view, respectively, showing an outline of a multi-stage press 1 for producing flooring materials and a take-out device therefor.
FIG. 5 is a side view of the multi-stage press 1 and the take-out device shown in these figures. The unloading apparatus shown in these figures is a multi-stage unloader in which three pressed plates 3 are horizontally transferred and supplied from a press plate 2 of an adjacent multi-stage press 1 in a state of being arranged in front and rear. It has a shelf 4.

The unloader shelf 4 includes a step portion 4B and an unloader shelf main body 4A. The step portion 4B is located on the left side of the unloader shelf main body 4A in FIGS. The step portion 4B stacks the pressed plates 3 supplied from the unloader shelf main body 4A. Therefore, the step 4B is disposed on the discharge side of the unloader shelf main body 4A. The step portion 4B is
It is arranged at a lower position with respect to the unloader shelf main body 4A. The apparatus shown in the figure has three pressed plates 3 at the step portion 4B.

The unloader shelf 4 is inclined forward and downward so as to transfer the supplied pressed plate 3 forward. The unloader shelf 4 is a roller conveyor in which a plurality of freely rotatable rollers are arranged in parallel. The roller conveyor can quickly transfer the plate 3 to be pressed forward at a gentle inclination angle. However, the unloading device of the present invention does not specify the unloader shelf 4 as a roller conveyor. The unloader shelf can also transfer the plate to be pressed forward by microvibration, for example. Further, the plate to be pressed may be slid and transferred forward by using a sliding surface made of fluororesin or the like having a small frictional resistance.

Since the stepped portion 4B is formed by laminating three pressed plates 3, it is designed to have a width on which one pressed plate 3 can be placed.
