Description

[Detailed Description of the Invention] [Object of the Invention] 1. The present invention corrects sheets that have been printed, cut, glued, and folded at right angles, stacks them, and uses the weight of the sheets and pressure from above to The present invention relates to a method and device for receiving sheets in a squaring section that ensures gluing and discharges stacked sheets to a counter ejector.

Conventional technology Conventionally, the first sheet fed by rollers, belts, etc. from previous processes such as printing, cutting, gluing, folding, etc., does not easily enter the sheet receptacle even if there is inertia, so it is difficult to manually handle the first sheet. This has had drawbacks such as the sheet being flattened, the amount of stacking at the rectangular correction section being inconsistent, and the sheet standing on end, especially in the case of short sheets.

Problems to be Solved by the Invention The present invention automatically supports the first 1 to 3 sheets fed from the previous process by rollers, belts, etc. on the front upper and lower sheet holders and the rear upper and lower sheet holders. In addition, the sheets are straightened at right angles, and the sheets are pressed by their own weight and air is blown from above the sheets to ensure gluing, and the top edge position of the stacked sheets is kept constant. It is an object of the present invention to provide a sheet receiving method and device for stacking fed sheets on top of stacked sheets.

[Structure of the invention]

Means for Solving the Problems In view of the above, the present invention corrects the right angle, and after supporting the first 1 to 3 sheets on a horizontal sheet holder, the horizontal sheet holder is moved back. The seats are supported by the front upper and lower seat holders and the rear upper and lower seat holders, and the front and rear upper and lower seat holders are moved up and down to keep the upper end of the stacked sheets at a constant position, and to prevent the weight of the seats and the weight from above the seats. The sheet receiving method presses the sheet by blowing out air, and a pair of right-angle straightening plates are installed on the left and right sides of the hopper, and in front of the right-angle straightening plates, there is a front vertical sheet holder that can move up and down, and a rear vertical sheet holder that can be moved up and down. An attempt has been made to solve the above-mentioned drawbacks by providing a sheet receiving device in which a seat I/receiver is installed, a horizontally slidable horizontal sheet receptacle is installed on the leading edge, and an air blower and an image sensor are separately installed. It is.

Function The present invention straightens the sheets fed from the folding section using the right angle straightening plate, and after supporting the first 1 to 3 sheets on the horizontal sorting tray, the horizontal sheet tray is moved back. The sheets are supported and set by the front upper and lower sheet holders and the rear upper and lower sheet holders, and the front and rear upper and lower sheet holders are moved up and down to keep the upper end of the stacked sheets at a constant position, and the sheets are placed above the hopper section. The stacked sheets are pressed and bonded using the installed air blower and the sheets' own weight to ensure gluing.

Below, one embodiment of the present invention will be described based on the drawings. 1 is a squaring part (right angle correction part) connected to the folding part which is the previous process, and below the squaring part 1. A sheet ejecting section 2 is arranged in a row so as to extend further forward, and a counter ejector 3 is arranged in a row in front of the sheet ejecting section 2.

First, to explain the squaring part 1, there is a hopper part between a rear base 5 having a feed roller 4.4a connected to the folding part above and a front base 6 disposed in front of the rear base 5. A pair of right angle straightening plates 8 are installed on the left and right sides of the hopper section 7 so as to hang down from the upper part of the tip of the rear base 5 through an L-shaped flange 9. At the front, vertically installed front upper and lower seat receivers 10 and rear upper and lower seat receivers 11 are installed vertically, which can be adjusted steplessly by a motor drive, etc., and horizontally slidable horizontally above the hopper section 7 are installed on the front base 6. A horizontal sorting receiver 12 is installed.

Further, an air blower 13 and an image sensor 14 are installed above the hopper section 7, and a rear light plate 15 is installed below the rear base 5 so as to be able to slide forward. A front light plate 16 is installed.

Next, the sheet discharging section 2 will be described. Reference numeral 17 is a sheet discharging belt that is stretched below the hopper section 7 and is stretched higher in front toward the counter ejector 3 than the rear edge position of the hopper section 7. The speed of the ejection heald 17 is made higher than the belt speed of the folding section by one sheet M.
A pressing belt 18 is stretched above the sheet ejection heald 17 to correspond to the above.

Further, a rotating delivery roller 19 is installed below the hopper section 7 at the rear edge of the hopper section 7 and above the sheet discharge belt 17, and a rotating delivery roller 19 is installed at the front edge of the hopper section 7 below the hopper section 7. And sheet ejection heald 17
A timing cam 20, which is an eccentric cam that is directly driven by a pulse motor or connected to a drive device via a clutch and a brake, is installed at approximately the same height as the sheet ejector [7] and the sheet M. has been achieved.

Next, the counter ejector 3 will be explained. Reference numeral 21 is a base that is installed upright at the base end of the counter ejector 3.
A sheet ejection heald 17 is extended, and a sheet introduction heald 22 is stretched in front of the sheet ejection bell eye 7 and is inclined from the sheet ejection heald 17 so that the front side is higher. A push-up cam 23 having a convex portion is provided near the lower part of the seat introduction heald 22 at approximately the center thereof, and a push-up member movable up and down approximately at the same height as the seat belt 22 is provided in front of the seat introduction heald 22. 24, and a stopper 25 higher than the sheet introduction heald 22 is installed in front of the push-up member 24.

Reference numeral 26 denotes a kicker installed on the base 21, and a cylinder 27 is connected to the kicker 26.
The tip of 6 is designed to be able to actuate diagonally downward forward force,
Also, both sides of the kicker 26 have a forward and upward movement of approximately 180 mm.
Two pairs of sort receiving claws 28.28a, 2 with different degrees of phase
9.29a is installed.

Note that 30 is a sheet ejection belt that is horizontally stretched in front of the stopper 25 and slightly higher than the stopper 25.

Next, the operation of the sheet receiving method and apparatus according to the present invention will be explained. The sheet M fed from the folding section via the feeding roller 4.4a of the squaring section 1 is transferred to the hopper section 7.
At the same time, the horizontal sheet receiver 12 is slid forward to be positioned above the hopper section 7, and the first one to three sheets M are supported on the horizontal sheet receiver 12. Horizontal sheet receiver 1 after tightening
2 is moved backward, and the seat M is supported by the front upper and lower sheet receivers 10 and the rear upper and lower sheet receivers 11. 11 is moved up and down to keep the upper end position of the stacking sea 1-M constant, and the air blower 13 is installed above the hopper section 7.
Then, the stacked sheets M are pressed and bonded by the weight of the sheets M to ensure gluing.

Next, the sheets M are stacked up, and the sheets M that have been glued and crimped are discharged from the lower part of the hopper section 7. As the timing cam 20 rotates, the sheet discharge belt 17 and the sheets M come into contact with each other and are separated, and the sheets M are discharged intermittently. Specifically, when the convex portion of the timing cam 20 presses the sheet M upward and the sheet ejection belt 17 and the sheet M are separated, the sheet M
When the sheet M is not ejected and the convex portion of the timing cam 20 is positioned downward and the sheet ejecting heald 17 is in contact with the sheet M, the sheet M is ejected by the action of the sheet ejecting heddle 7 and the delivery roller 19. Therefore, since the sheet ejection belt 17 and the sheet M come into contact with each other, the ejected sheet M
There is a gap between the two.

Next, the sheet M discharged from the hopper section 7 is introduced into the counter ejector 3 by the sheet discharge belt 17 and the sheet introduction heald 22, comes into contact with the stopper 25 and stops, and the push-up cam 23 rotates. The convex part lifts the sheet M, and the rear end of the sheet M is lifted and held upward by one of the sheet receiving claws 28.28a moving forward and upward, and when the push-up cam 23 further rotates, the rear end of the sheet M is lifted up and held upward. Stacked sea) M
The sheet M passes below, the next sheet M is introduced under the stacked sheets M, and the push-up cam 23 and the other sheet receiving claw 29.29a are activated to stack the next sheet M together with the next new sheet M. The sheets M held above are stacked from below, and a predetermined number of sheets 1-M are stacked by sequentially repeating the operation of the push-up cam 23 and the sheet receiving claws 28, 28a and 29, 29a.

Next, the kicker 26 will be activated, but at this time, the timing cam 20 of the sheet ejecting section 2 will be activated so that the sheet M
While preventing one sheet from being ejected, the push-up member 24 is operated to raise the leading end of the stacked sheet M above the stopper 25.

Next, the trigger 26 is operated diagonally downward to receive the lowest end of the seat M, and after receiving the lowest end of the seat M, the lowermost end of the seat M is placed horizontally with the forward position in the direction of travel of the seat M. While lifting the kicker 26 so that the sheet M stacked up to a predetermined number is sent out, the kicker 26 moves backward while maintaining its horizontal position and descends downward at the retreat limit.

In the above case, the lower end of the kicker 26 moves in the direction away from the rear end of the sheet M by lowering it, so the lower end of the kicker 26
[Effect of the Invention] In short, the present invention achieves right angle correction, so that the sheet M that is deviated when folding the sheet M at the folding section can be corrected. In order to straighten the right angle, it is possible to achieve even gluing and crimping, smooth conveyance through the sheet ejection section 2 and counter ejector 3, eliminate distortion when bundling and packaging a predetermined number of sheets, and also prevent the first 1 Since approximately 3 to 3 sheets M are supported by the horizontal sheet receiver 12, automation can be performed without requiring human intervention at the start of operation, and by retracting the horizontal sheet receiver 12, the sheets M can be transferred to the front upper and lower sheet receivers 10. and supported by the rear upper and lower seat receivers 11, and the front upper and lower seat receivers 10.
Since the rear upper and lower sheet receivers 11 are moved up and down to maintain a constant upper end position of the stacked sheets M, the sheets M sequentially fed from the folding section can be neatly stacked on top of the stacked sheets M, and Since M does not stand on its head, it can accommodate sheets M of various sizes, and since it presses the sheet M using its own weight and air is blown out from above the sheet 1-M, it is possible to apply adhesive pressure evenly. The practical effects are enormous.
