The operation of the paper feeding device I will be described. This paper receiving guide member 73, 73a of this paper receiving guide frame 72
In inserting and feeding the paper T into the space and the gap between the members 73b and 73c, first, as shown in FIG. 2, the fluid pressure cylinder 36 of the paper take-out means K is in the retracted position, and the shelf member of the paper storage device H. The sheets T, T, ... Placed on the sheet 39 are pushed toward the uppermost surface by a driving device (not shown), and the upper surface of the uppermost sheet Ta is lowered to reach the lowermost end by vacuum suction. It stops at a position where it contacts the lower surface of the pack 37.

When the piston rod is extended by the operation of the fluid pressure cylinder 36 and the vacuum suction pack 37 descends, the uppermost paper Ta is sucked and held by the vacuum suction pack 37. When the piston rod of the fluid pressure cylinder 36 is in the retracted state, the paper Ta rises and the next paper Tb remains on the shelf member 39 of the paper storage device H (see FIG. 3). At this time, the fluid pressure cylinder 36 and the bracket 38 of the paper take-out means K are at the uppermost position, and the piston rod of the fluid pressure cylinder 36 is in the retracted state.

While maintaining this state, the paper moving means M is

When the paper Ta conveyed by the paper moving means M approaches the position of the paper holding means L corresponding to the paper receiving guide frame 72, it is decelerated by the operation of a limit switch (not shown). Since the motor 31 with a machine stops and the vacuum suction pad 37 releases the suction state, it falls on the support member 49. The actuator 54 is actuated in response to a time-lapse signal from a timer (not shown) that is activated when the suction state is released, and the arms 48 and 48a are angularly displaced by 90 degrees. In this state, one end of the paper Ta is stopped by the side walls 55, 55a and remains on the support members 49, 49a. Then, in response to the completion signal of the 90-degree angular displacement of the arms 48, 48a, the fluid pressure cylinders 51, 51a move in unison, and the supporting members 49, 49a move outward in the span direction. It falls onto the paper receiving guide frame 72.

This paper Ta is a paper receiving guide member 73,
It falls from the front end side edge into the gap with 73a and stays on the shutter member 56 at the intermediate position of the paper holding means L. Further, when the fluid pressure cylinder 57 operates and the piston rod retracts and the shutter member 56 is opened, the paper Ta is
It drops further down and rests on the stopper 60 (see FIG. 9).

On the other hand, the vacuum suction pad 37 is retracted by the operation of the fluid pressure cylinder 36, and the reverse rotation of the motor 31 with a speed reducer causes the paper take-out means K to return to the retracted position above the paper storage device H. . Subsequently, the vacuum suction pad 37 is lowered by the operation of the fluid pressure cylinder 36. Then, the vacuum suction pad 37 presses the second most recent paper Tb placed on the support shelf of the paper storage device H from the previous time, and the upper surface of the paper Tb comes into contact with the vacuum suction pad 37 and is suction-held. It Then, the fluid pressure cylinder 36 is operated and the vacuum suction pad 37 is retracted.

While holding the paper Tb by the vacuum suction pad 37 in the retracted position, the paper moving means M drives the motor 31 with a speed reducer to rotate the chain 31 counterclockwise.
The sliders 24, 24a are moved to the right in FIG.
The bracket 35 and the bracket 3 that support the fluid pressure cylinder 36 that moves the vacuum suction pad 37 up and down.
3 is moved to the right to a position where the limit switch cam 45a and a limit switch (not shown) interfere with each other and stop due to the operation of the limit switch. in this case,
Although passing through the cam 45b on the way, a control device (not shown)
Since a sequence for invalidating the output signal is incorporated by the, the motor 31 with a reducer does not stop and operate.

The second sheet Tb from the previous top conveyed by the sheet moving means M is the sheet receiving guide frame 72a.
When approaching the position of the paper holding means L corresponding to, the motor 31 with a speed reducer is stopped by the operation of a limit switch (not shown), and the vacuum suction pad 37 releases the suction state. To fall. The actuator 54 is actuated in response to a lapse of time signal from a timer (not shown) that is activated when the suction state is released, and the arm 4
8, 48a are angularly displaced by 90 degrees. In this state, this paper T
b is supported at one end by the side walls 55 and 55a and is supported by the support member 4
It remains at 9, 49a. And the arms 48, 48a
In response to the completion signal of the 90 degree angular displacement of the fluid pressure cylinders 51 and 51a, the fluid pressure cylinders 51 and 51a are simultaneously actuated, and the support member 49,
Since 49a moves outward in the span direction, the paper Tb falls on the paper receiving guide frame 72a.

This paper Tb is a guide member 73 for receiving this paper.
It falls from the edge of the leading end into the gap between b and 73c and stays on the shutter member 56a at the intermediate position of the paper holding means L. Further, when the fluid pressure cylinder 57a operates and the piston rod retracts and the shutter member 56a is opened, the paper Tb falls further downward and is placed on the stopper 60a (see FIG. 9).

In this state, the fluid pressure cylinder 5
9, 59a are actuated to press the paper Ta, Tb against the signature stack W by the paper pressing metal fittings 58, 58a, and in that state, the fluid pressure cylinder 77 connected to the pusher 76 from the signature stacking section B is released. By operating to extend the piston rod, the signature stack W and the paper Ta, Tb are moved to the fluid pressure cylinders 59, 59a and the paper press fittings 58, 58.

The signature stack W is sandwiched between the two sheets Ta, Tb in order to be moved to 9b and 79c.

The paper Ta, Tb is moved from the signature stacking section B of the signature stacking body W to the binding section C, and the portions protruding from the bottom of the signature stacking body W are endless belts 63, 63.
Since the endless belts 63 and 63a, which are initially in the vertical state, are twisted by 90 degrees to be in a horizontal state by being sandwiched between a and the guides 64 and 64a, the papers Ta and Tb also move accordingly. . This paper Ta, Tb
From the ends of the guides 64, 64a to the notches 20, 20
At a, the endless belts 63, 63a are sandwiched between the signature stack W and moved, and are folded so as to contact the bottom of the signature stack W (see FIGS. 14A, 14B, and 14C).

The signature stack W in the signature stacking unit B
The front side Wa and the rear side Wb of the paper are applied with the papers Ta and Tb, respectively. When the band 13 is used to bind the signature stack W in the binding portion C, the portion protruding from the upper surface of the signature stack W is folded onto the upper surface of the signature stack W. The signature stack W has a front surface Wa and a rear surface Wb on which the paper Ta, T
The band 13 is bound by the band 13 at the binding portion C with b being applied. Therefore, the signature stacks W, W, ... Are normally bundled and are prevented from being damaged by the band 13.
The operation of each part is performed based on sequence control by a control device (not shown). The form of these signature delivery paths and the direction of travel of the signatures are not limited to this embodiment, and may be the configuration described in the prior art 1.
