[0020]
The upper suction conveyance belt means 3 as the second suction conveyance belt means receives the tip of the band 1 just before the rotary cutter 4 cuts the band 1 and pulls it together with the first suction conveyance belt means 2. When 4 cuts the strip 1, the separated sheet 1 a is conveyed in the right direction in FIG. 1. The upper suction conveyance belt means 3 is driven slightly faster than the first suction conveyance belt means 2. As shown in FIG. 3B, the upper suction / conveying belt means 3 includes a thin endless belt 16 in which a large number of ventilation holes 16a are formed, and the belt 16 is along the traveling direction of the belt-like object 1. As shown in FIG. These belts 16 are arranged between a drive shaft 17 and a driven shaft 18 that are arranged in a direction perpendicular to the traveling direction so that the lower traveling portion thereof is in contact with the upper surfaces of the strip 1 and the sheet 1a. And is driven at a speed slightly higher than the traveling speed of the belt 7 of the first suction conveyance belt means 2.

[0021]
As shown in FIG. 3A, a suction box 19 is arranged for each belt 16 of the upper suction conveyance belt means 3, and suction ports 19a, 19b, 19c, 19d formed on the lower surface of each suction box 19. However, the upper suction conveyance belt means 3 faces the portion of the belt 16 to be in contact with the sheet 1a from the back side. The suction ports 19a, 19b, 19c, and 19d are sequentially arranged along the traveling direction of the sheet 1a, and are formed so that the opening area becomes smaller from upstream to downstream. Specifically, the suction ports 19a, 19b, and 19c are long holes that are formed so that the opening area gradually decreases between them, and the suction ports 19d are arranged so that the pitch gradually increases between them. Round holes. For this reason, the suction force of the upper suction conveyance belt means 3 is reduced toward the downstream side, and the restraining force on the single wafer 1a is gradually relaxed. Each suction box 19 is connected to a blower (not shown) and exhausted by a suction action by the blower.
[0022]
As shown in FIG. 1, the peeling member 5 is disposed on the downstream side of the upper suction conveyance belt means 3, and as shown in FIG. 4, the single wafer 1a conveyed by the upper suction conveyance belt means 3 is provided. Is peeled downward from the belt 16 of the upper suction conveying belt means 3. The peeling member 5 is specifically constituted by a brush, and is intermittently disposed on the drive shaft 20 passed between the left and right frames (not shown) so as to enter between the suction boxes 19 of the upper suction conveyance belt means 3. Yes. The peeling member 5 can also be constituted by a member such as a cam other than a brush. The peeling member 5 rotates at the same rotational speed as the plate cylinder of the printing press. When the sheet 1a is conveyed by the upper suction conveyance belt means 3, the rear end portion of the sheet 1a is conveyed. In this case, the rear end portion is peeled off from the surface of the belt 16 of the upper suction conveyance belt means 3 against the suction force of the upper suction conveyance belt means 3. Since the suction ports 19c and 19d of the suction box 19 are small in the vicinity of the peeling member 5, the suction force of the upper suction conveyance belt means 3 is reduced, and the rear end of the sheet 1a is the upper suction. It is easily peeled off from the belt 16 of the conveying belt means 3. The rear end portion of the peeled sheet 1a is received and conveyed by the lower suction conveyance belt means which is the third suction conveyance belt means 6.
[0023]
In order to transfer the sheet 1a from the upper suction conveyance belt means 3 to the lower suction conveyance belt means 6 more smoothly and reliably, the contact portion of the peeling member 5 with the sheet 1a is set to the sheet 1a. It is desirable to change slightly according to the material, speed, etc. Therefore, a phase changing means for shifting the phase of the peeling member 5 with respect to the sheet 1 a is provided in the driving portion of the peeling member 5. The phase changing means adopts a known configuration, and detailed description thereof is omitted.
[0024]
As shown in FIGS. 1 and 4, the lower suction conveyance belt means 6 includes an endless belt 21, and a drive shaft 22 and a driven shaft 23 that stretch the belt 21 in the traveling direction of the sheet 1 a.
[0025]
The belt 21 of the lower suction conveyance belt means 6 is a tough thin belt provided with a large number of ventilation holes at a constant pitch in the width direction and the length direction, like the belt 16 of the upper suction conveyance belt means 3. A plurality of strips 1 are arranged in parallel along the traveling direction of the strip 1. These belts 21 are arranged so as to receive the sheet 1a from the lower surface thereof, and are hung between a driving shaft 22 on the start end side and a driven shaft 23 on the rear end side arranged in a direction perpendicular to the traveling direction. Then, the vehicle travels at a speed of, for example, about 1/10 to 1/20, which is lower than the traveling speed of the belt 16 of the upper suction conveyance belt means 3.
[0026]
The drive shaft 22 on the start end side is formed as a suction roller, and a number of suction holes 22a are formed on the surface thereof. The drive shaft 22 is disposed directly below the peeling member 5. The drive shaft 22 is connected to a blower via a rotary joint (not shown), and sucks air from the suction hole 22a so as to attract the sheet 1a on the belt 16 of the upper suction conveyance belt means 3. As shown in FIG. 4, when the peeling member 5 peels off the sheet 1 a from the belt 16 of the upper suction conveyance belt means 3, the rear end of the sheet 1 a is the belt 21 of the lower suction conveyance belt means 6. It is adsorbed on the surface of the drive shaft 22 via
[0027]
Further, a suction box 24 is disposed at a position surrounded by the endless belt 21 of the lower suction conveyance belt means 6, and although not shown, its suction port faces the upper travel path of the belt 21 of the lower suction conveyance belt means 6 from its rear surface. It is out. The suction port is a long hole extending along the traveling direction of the sheet 1a, and the opening area is reduced toward the downstream side. Therefore, the suction force of the sheet 1a is also reduced toward the downstream. The suction box 24 is exhausted by a blower (not shown). The belt 21 of the lower suction conveyance belt means 6 travels at a lower speed than the belt 16 of the upper suction conveyance belt means 3, receives the sheet 1 a peeled off from the upper suction conveyance belt means 3, and decelerates it. 1 is discharged onto the pallet 26 of the deposition unit 25 shown in FIG.
[0028]
As shown in FIG. 1, the accumulation unit 25 includes a pallet 26 that is suspended by a chain 27 and the like so as to be movable up and down. The pallet 26 is controlled by a control device (not shown) and descends as the amount of sheets 1a deposited increases.
[0029]
In addition, joggers 28 a and 28 b and a temporary receiving device 29 are provided on the upper portion of the deposition unit 25.
[0030]
The joggers 28a and 28b apply vibration to the single-piece 1a discharged from the lower suction conveyance belt means 6 onto the mountain 1b of the single-piece 1a to align their edges.
[0031]
When the peak 1b of the sheet 1a reaches a certain height, the temporary receiving device 29 advances the fork-shaped receiving member 29a from below the lower suction conveyance belt means 6 onto the peak 1b of the sheet 1a. It is made to receive the sheet 1a which falls. While receiving the succeeding sheet 1a with this temporary receiving device 29, the pile 1b of the already stacked sheets 1a is carried out of the machine, and a new pallet 26 is raised to just below the receiving member 29a. Then, the receiving member 29a is moved back to the original position, and the temporarily received single wafer 1a is dropped onto the pallet 26. Thereafter, the sheet 1a is deposited on the pallet 26 in the same manner as the previous time.
[0032]
When the temporary receiving device 29 is provided in the stacking portion 25 in this way, a space for the receiving member 29a of the temporary receiving device 29 to enter and exit from the stacking portion 25 must be provided. The drop H from the means 6 until the sheet 1a drops onto the peak 1b of the sheet 1a is increased, and the sheet 1a is simply released from the lower suction conveyance belt means 6 onto the stacking portion 25. It cannot be properly stacked due to bending or breaking.
[0033]
Therefore, as shown in FIG. 1, a Coanda box 30 is installed above the accumulation unit 25 so as to be continuous with the belt 16 of the upper suction conveyance belt means 3.
[0034]
As shown in FIG. 5, the Coanda box 30 is formed by forming a large number of air ejection holes 30a on the bottom surface so that air flows along the longitudinal direction of the box on the bottom surface of the elongated box. Corresponding to each of the belts 16 of the conveying belt means 3, it is arranged along the traveling direction of the sheet 1a. The air ejection holes 30a are arranged so that the pitch increases from the upstream side to the downstream side of the flow of the sheet 1a, and the flow velocity of the air decreases as it goes downstream. . As shown in FIG. 5 (A), when air is supplied from a blower (not shown) into the Coanda box 30, the air is fed from a large number of air ejection holes 30a along the bottom surface of the ejection box 1a. The sheet 1a is conveyed without fluttering under the Coanda box 30 due to the Coanda effect. Further, since the suction force of the Coanda box 30 decreases toward the downstream side, as shown in FIG. 6, the tip of the sheet 1a gradually descends and comes into contact with the front jogger 28a. Thereby, even when the said head H in the deposition part 25 is large, the sheet 1a is stacked appropriately.
[0035]
The Coanda box 30 may be installed horizontally on the deposition unit 25, but is desirably installed so as to be inclined slightly downward as shown in FIGS. For this reason, the sheet 1a descends at a more appropriate angle and comes into contact with the front jogger 28a.
[0036]
Next, a series of operations of this trimming discharge device will be described.
[0037]
The rotary cutter 4 cuts the strip 1 each time it rotates. At the time of this cutting, the front end of the strip 1 passes through the rotary cutter 4 before entering the cutting state, enters under the belt 16 of the upper suction conveyance belt means 3, and is sucked upstream of the upper suction conveyance belt means 3. The For this reason, the belt-like object 1 is pulled between the upper suction conveyance belt means 3 and the first suction conveyance belt means 2 with an appropriate force. The strip 1 is cut by the rotary cutter 4 immediately after that.
[0038]
The belt 16 of the upper suction conveyance belt means 3 travels at a slightly higher speed than the belt 7 of the first suction conveyance belt means 2, and therefore, between the rear end of the separated sheet 1 a and the front end of the strip 1. There is a gap in it. Thereby, it is possible to prevent the tip of the succeeding sheet 1a from colliding with the rear end of the preceding sheet 1a.
[0039]
When the cut sheet 1a is conveyed by the upper suction conveyance belt means 3 above the lower suction conveyance belt means 6, the peeling member 5 pushes the rear end portion of the sheet 1a to the upper suction conveyance belt means 3. The belt 16 is peeled off from the belt 16 against the suction force and pressed onto the driving roller 22 of the lower suction conveyance belt means 6 as shown in FIG. The rear end portion of the sheet 1a is curved following the surface of the driving roller 22, so that the leading edge of the subsequent sheet 1a does not sink under the preceding sheet 1a but behind the preceding sheet 1a. Pass over the edge. The single wafer 1a adsorbed by the drive roller 22 is also adsorbed on the belt 21 and discharged onto the stacking portion 25 in a decelerated state.
[0040]
The front end portion of the sheet 1 a that comes out from the belt 21 of the lower suction conveyance belt means 6 at a low speed is captured by the Coanda box 30 and travels along the bottom surface of the Coanda box 30. Since the suction force of the Coanda box 30 decreases as it goes toward the tip of the box, the sheet 1a is gradually lowered to fall on the head so that it does not bend or bend over the mountain 1b of the sheet 1a. To deposit.
[0041]
When the crest 1b of the sheet 1a reaches a certain height, the receiving member 29a of the temporary receiving device 29 advances from below the lower suction conveyance belt means 6 onto the crest 1b of the sheet 1a and drops. Receive leaf 1a. While receiving the succeeding sheet 1a with this temporary receiving device 29, the pile 1b of the already stacked sheets 1a is carried out of the machine, and a new pallet 26 is raised to just below the receiving member 29a. Then, the receiving member 29a is moved back to the original position, and the temporarily received single wafer 1a is dropped onto the pallet 26.
[0042]
Thereafter, the sheet 1a is deposited on the pallet 26 in the same manner as the previous time.
[0043]
