[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stack device.

[0002]

2. Description of the Related Art Heretofore, a stacking device has been used in which foams continuously discharged by discharge rollers are sequentially stored in a storage box.

In a stacking apparatus, the foam is continuously and rapidly discharged by a discharge roller. For this reason,
The foam collides with the elevation wall of the storage box and deforms like a wave. The wavy form usually blocks the passage of the following form. For this reason, the foam front end of the succeeding foam discharged by the discharge roller collides with the foam rear end of the preceding foam to cause a jam, and the foams may not be stored neatly in the storage box.

Therefore, conventionally, a hitting lever, which is rotated by a motor and hits the rear end of the foam downward, is provided at a position on the exit side of the discharge roller where the passage of the foam is blocked. The striking lever is rotated in synchronization with the form discharge timing, and strikes the trailing end of the preceding form below the passing path of the succeeding form so that the leading end of the succeeding form collides with the trailing end of the preceding form. This is to prevent occurrence.

[0005]

However, the prior art has the following problems.

It is necessary to synchronize the operation timing of the hitting lever with the discharge timing of the foam, and as a result, it is necessary to adjust the timing according to changes in the type (length) of the foam, the feed speed of the foam, and the like. is there.

[0007] As the form feed speed increases,
The operation timing of the striking lever becomes inappropriate due to a form feeding error or the like, and it is difficult to perform an accurate striking operation. Also, depending on the irregular waving state that occurs when the foam is stored, a state where the hitting cover does not contact the rear end of the foam may occur. Therefore, there is a possibility that the striking lever may hinder the passage of the front end of the foam, or may cause inconvenience such as not appropriately striking the rear end of the foam.

[0008] The present invention is intended for any of the continuous discharge
It is an object of the present invention to surely and sequentially store the forms in the storage box even for the forms of the varieties .

[0009]

According to a first aspect of the present invention, there is provided a stacking apparatus for successively storing foams continuously discharged by discharge rollers in a storage box. At the position where the passage of the foam is interrupted, a striking lever that jumps up due to the collision of the foam tip and knocks down the rear end of the foam by the return after the jumping is installed , engages with the striking lever, and raises the striking lever.
In addition to restricting the initial position before setting, set the initial position.
It is provided with a stopper that can be fixedly changed .

According to a second aspect of the present invention, there is provided the first aspect of the present invention, further comprising a spring for biasing the hitting lever in a recoil direction.

[0011]

[0012]

According to the first aspect of the present invention , the following:
Has the effect of

The striking lever is flipped up by the collision of the leading end of the preceding form discharged from the discharge roller. Then, the hitting lever that has been flipped up hits the rear end of the foam of the preceding form below the passing path of the succeeding form by the subsequent return,
This prevents a jam in which the leading end of the succeeding form collides with the trailing end of the preceding form.

[0014] The hitting lever is in its initial position before it jumps up.
Is regulated by the stopper, and tapping is performed according to the foam type.
