Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a device for separating a calendar.

(Conventional Technology) Conventionally, a calender has a binding tool attached to one end by a winding machine, and the binding tool is sent from the winding machine through a chute with the binding tool as a tip, and the calender is placed on the product stand against the product stand. It is dropped from an oblique direction and can be stacked in sequence,
Twenty-five volumes are usually stacked in a bundle and then removed from the product table. Then, a bundle of 25 books is alternately stacked so that the binding metal part does not weigh, and is housed or packaged in units of 50 books or 100 books.

(Problems to be Solved by the Invention) In the above-mentioned prior art, since the calender is delivered obliquely onto the product stand with the binding metal fitting as the tip, it follows the preceding calendar already on the product stand. The calendar's binding metal hits and scratches the preceding calendar,
The other end of the calendar (the side that is not bound by the binding metal fitting) rolls up due to the recoil of the binding metal fittings, and the subsequent calendar is sent on top of it and stacked, and the calendar where the curling up has occurred. The other end of may be bent.

Therefore, a pair of left and right receiving plates that receive the left and right sides of the calendar from the top are provided, and the left and right outer end sides of these left and right receiving plates are rotatably supported around the front-rear axis. The calenders sent out forward are temporarily received by the receiving plates, and then the left and right receiving plates are rotated downward to drop the calendars on the left and right receiving plates. It is conceivable to stack one by one without failing to damage the calendar.

However, if the width of the left and right receiving plates is formed to be the same across the front-rear direction and the distance between the left and right inner end edges of the left and right receiving plates is constant over the front-rear direction, the left and right receiving plates are moved downward. When rotating and dropping the calender on the receiving plate, the calender drops in a substantially horizontal state, so the drop may become unstable due to air resistance received on the lower surface of the calender, and the drop position may vary.

If the falling positions vary, it is troublesome to properly arrange the stacked calenders after stacking a predetermined amount of calenders and before storing or packaging in the case.

In view of the above problems, it is an object of the present invention to provide a calender separating device that can stack the calenders without damaging the calenders, and that can favorably stack the calenders.

(Means for Solving the Problem) The technical means taken by the present invention to achieve the above-mentioned object is to receive on the upper surface both left and right sides of the calendar H sent forward one by one with the binding metal fitting as the tip. It is provided with a pair of left and right receiving plates 33 to be stopped, and the left and right outer end sides of these receiving plates 33 are rotatably supported around the front-rear axis. It is a calendar volume separating device in which the calendars H that are sequentially sent out are stacked one by one by repeating the operation of dropping. The left and right receiving plates 33 are arranged in the left and right direction of the left and right receiving plates 33. The point is that the width between the edges is narrowed toward the front so that the distance between the edges gradually increases toward the front.

(Operation) In FIG. 1, the calender H to which the binding metal fittings are attached by the winding machine 3 is discharged from the chute 87 with the binding metal fittings as the tips. The calendar H is delivered to the pair of left and right receivers 5 via the delivery mechanism 4, and both sides of the calendar H are received on the receiving plate 33 located at the position of the calendar receiving portion A of the receiving body 5. At this time, the calendar H is detected by the proximity switch 6, the count value is counted up by the detection signal, and the drive mechanism 7 is driven. By the drive of the drive mechanism 7, each receiver 5 is rotated 1/4 in the directions of arrows E and F in FIG. As a result, the receiving plate at the position of the calendar receiving portion A
33 moves to the lower position in the vertical direction of the receiver 5, and the calendar H
The receiving plate 33 is retracted from the projection area of, and the calender is dropped onto the transfer mechanism 8. At this time, the receiving plate 33 at the vertically upper position of the receiving body 5 moves to the position of the calendar receiving portion A and waits for the next calendar H. By repeating the above operation, the calenders H are stacked on the transfer mechanism 8 from directly above, while the transfer mechanism 8 is stopped. When the number of the stacked calendars H reaches the required number, the transfer mechanism 8 is driven by the required amount to transfer the stacked calendars H. Then, the calenders H stacked by repeating the above operation are sent in series on the transfer mechanism 8, and the stacked calenders H are stocked on the transfer mechanism A and separated.

In the above structure, the upper and lower belts 17 and 18 of the feeding mechanism 4 are circulated in the direction of arrow B in FIG. Calender H discharged from chute 87 of winding machine 3
Is sandwiched between the upper and lower belts 17 and 18 with the binding metal fitting as the tip and is transferred upward and delivered between the receiving members 5. The tip of the calender H sent between the receiving bodies 5 is a contact plate.
While abutting against 44, the abutment plate 44 abuts against the abutment portion 45 and the movement of the calender H is stopped and received on the receiving plate 33 located at the position of the calender receiving portion A. At this time, a detection signal is sent from the proximity switch 6 to the control device 47, the count value is counted up, and at the same time, a drive signal is sent to the drive mechanism 7. The motor 48 of the drive mechanism 7 is constantly rotated, and the transmission shaft 54 is driven by the drive signal from the control device 47.
Connected to 48 output shafts. At this time, the mesh clutch
55 is released. Therefore, the drive arm 58 is rotationally driven in the direction of arrow C in FIG. 1 by the power from the motor 48 via the winding transmission means 49. Then, when the drive arm 58 makes a half rotation, the transmission shaft 54 is disconnected from the motor 48, and the meshing clutch 55 is connected. Rotation of the drive arm 58 causes one drive arm to rotate.
The pin 66 of 48 is engaged with one groove 60 of the Geneva gear 57, and the Geneva gear 57 is rotated 1/4 in the direction of arrow D in FIG. At this time, the stopper pin 59 disengages from the groove 60 against the spring force, and is fitted into the next groove 60 (backward in the rotation direction) by the restoring force of the spring, and the Geneva gear 57 surely stops at 1/4 rotation. To be done. The rotational force of the Geneva gear 57 is transmitted to the receiving body 5 via the rotary shaft 61 and the bevel gears 62 and 63, and the left and right receiving bodies 5 rotate 1/4 in the directions shown by arrows E and F in FIG. 3, respectively. As a result, the receiving plate 33 located at the position of the calendar receiving portion A is moved to the calendar H.
At the same time as the calender H is dropped from the projection area of the above, the receiving plate 33 at the upper position in the vertical direction comes to the position of the calender receiving portion A and stands by. At this time, since the receiving plate 33 is gradually narrowed toward the front, the calender H is sequentially dropped from the tip, and a stable falling state is obtained without receiving much air resistance.

The calender H dropped from the receiver 5 falls on the belt 71 of the transfer mechanism 8 while being regulated by the guide plate 41 and the guide bar 78. In the motor 67 of the transfer mechanism 8, the calendar H is the belt.
The controller is stopped until the required number of books are stacked on the 71
When the count value of the counter reaches the value preset in 47, a drive signal is sent from the control device 47, and the motor 67 is driven. As a result, the belt 71 is driven via the chain 74 and the drive roller 69, and the weighted and stacked calendar H is transferred in the direction of arrow G in FIG. When the required amount is transferred, an engaging portion (not shown) provided on the chain 74 comes into contact with the limit switch 79 and a detection signal is sent to the control device 47, and a reverse drive signal is sent from the control device 47 to the motor 67. To be This causes the motor 67 to rotate in the reverse direction, returning the chain 74 to the initial position and stopping. At this time, power is not transmitted to the drive roller 69. The calendars stacked in the required amount by repeating the above-described operation are sequentially arranged and arranged in series on the transfer mechanism 8 to reach the product stand 82.

The present invention is not limited to the above-mentioned embodiment, and the receiving body 5 may be composed of three, two or one receiving plate 33.

(Effects of the Invention) According to the present invention, the calender sent forward with the binding metal fitting as the tip is received by the pair of left and right receiving plates one by one, and then dropped below the receiving plate. As they are stacked, they can be stacked without damaging the calendar.

Further, particularly in the present invention, the left and right receiving plates are formed to have a narrow width toward the front, and the interval between the left and right inner end edges of the left and right receiving plates is gradually widened toward the front. Therefore, when the left and right receiving plates are rotated downward to drop the calender on the receiving plate, the calender is sequentially dropped from the tip, so that it receives a little air resistance and a stable falling state is obtained. Thus, it is possible to minimize variations in the calender's drop position.
