Abstract

PURPOSE:To certainly perform lapping in a reverse inserted state without generating the mutual interference of the end parts of both printed books by pushing up the rear end of the preceding printed book in synchronous relation to the movement of the front end of the succeeding printed book and allowing the front end of the succeeding printed book to get under the rear end of the preceding printed book to lap both printed books in a mutually reverse inserted state. CONSTITUTION:The front end of the printed book supported and fed by a feed conveyor 1 catches up with the lag 22 of a chain conveyor 2 running at a speed lower than that of the feed conveyor 1 with the movement of the printed book to collide with said lag 22 and fed at the speed same to the running speed of the lag 22. Thereafter, the lag catches up with the rear end of the preceding book moved at a low speed in a state held between feed-out rollers 3 and gets under said printed book while raises the same and the printed book advancing in contact with the lag at the front end thereof gets under the preceding printed book. When the printed books are further sent out to reach the holding positions due to the rolls, they advance at the speed same to the peripheral speed thereof this time to transfer to a reverse inserted state. By this method, the bodies S not aligned at a width direction position fed from the collapse part B of a perforator part B of a perforator are aligned to be lapped in the reverse inserted state and can be transferred to the body feed conveyor C of a case- marking machine.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method and device for reverse-wrapping printed books during transport, and in particular to supplying printed books to a cover pasting machine etc. that uses a stream feed method. The present invention relates to a method and device for reverse-wrapping printed books suitable for.

[Conventional technology]

In a cover pasting machine that uses a stream feed method, when feeding the printed text to the cover pasting machine, the main text that is cut off one by one after the sewing machine is conveyed is placed upside down. It is necessary to wrap it and send it to the cover pasting machine.

Conventionally, there is no text reverse wrapping device suitable for this kind of use, but one possible method for wrapping the text is to wrap the rear end of the preceding text using a cam 01 as schematically shown in Figure 4. , as shown schematically in Figure 5, the rear end is also pushed up using solenoid 02,
As schematically shown in Fig. 6, a pair of left and right screws 03
Possible methods include a method of scooping up the water with a vacuum cleaner, a method of sucking it up with a suction cup 04 as schematically shown in FIG.

[Problem to be solved by the invention]

By the way, the following conditions are required for the book reverse lapping device.

fl) Be able to accommodate changes in the length of the text (290-500mrIJ).

(2) It must be able to accommodate changes in the width of the text (120 to 350 mm).

(3) Even if the thickness (number of sheets) of the main text changes, it should be easy to adjust accordingly.

(4) Variation in pitch after lapping is small (within 2 mm).

(5) The operating speed of the lapping device shall be synchronized with that of the line.

Looking at each of the above methods in light of these conditions, the cam type requires a mechanism to move the cam position according to the length of the text, and this mechanism must be operated in synchronization with the line operating speed. Since it is difficult to do so, the timing at which the rear end of the text is flipped up by the cam tends to be misaligned. Similarly, the solenoid type requires a mechanism to move the position of the solenoid, and requires sensing of the timing of flip-up. The screw type has the disadvantage that it is difficult to move the screw according to the length of the text, and if the text is wide, the scooping becomes unstable, and the operation is less reliable for thin objects. Also, even with the suction cup type, it is necessary to move the suction cup as the length changes.
If the width is wide, there is a high possibility of end sag, and if the material is multi-layered, the end sag will increase.

It is an object of the present invention to provide a method and apparatus for reverse-wrapping a printed book, which can essentially avoid the problems of each of the above-mentioned methods.

[Means to solve the problem]

In order to solve the above-mentioned problems, the method of the present invention wraps the printed books conveyed one by one from the previous process in an inverted state and sends them to the next process. While transporting the printing book at the feeding speed to the process, the following printing book is transported at a speed higher than the feeding speed, and the trailing edge of the preceding printing book is pushed up in synchronization with the movement of the front end of the following printing printing book. The method is characterized in that the front end of the following printing book is inserted below the rear end of the preceding printing book, so that both printing books are wrapped in an inverted state with respect to each other.

Further, in order to realize the above method, the apparatus of the present invention includes a conveyor that supports and conveys printed books, a chain conveyor that drives lugs arranged in parallel with the conveyor at a lower speed than the conveyor. The present invention is characterized in that a delivery roller is provided in front of the transport conveyor and delivers the printed books while being driven at a lower speed than the chain conveyor.

[Effect]

In the apparatus of the present invention, as the front end of the book supported and transported by the transport conveyor catches up with the lug of the chain conveyor, which runs at a lower speed than the transport conveyor, as it moves, it hits the lug, and the book is transported at the same speed as the running speed of the lug. . The lug then catches up with the rear end of the preceding printing book, which is being held by the delivery rollers and is moving at low speed, lifts it and slips under it, and as a result, the front end contacts the lug and advances. A printed copy slips under the preceding printed copy. and,
Furthermore, as the lug travels, the front end of the printing book advances below the preceding printing book, and when it reaches the nipping position of the delivery roller, it now advances at the same speed as the circumferential speed of the delivery roller. Complete the transition to Gyakusashimi state.

〔Example〕

Next, an explanation will be given based on an embodiment in which the present invention is applied to a reverse wrapping device for text in the manufacture of passbooks.

FIG. 1 is a perspective view showing a reverse lapping device according to an embodiment of the present invention. As shown in the figure, this reverse wrapping device A is built into a frame independent from the crushing section B of the sewing machine device and the text feed conveyor C of the cover pasting machine, and includes a conveyor l, a chain conveyor 2, and a delivery roller. It has 3.

First, the conveyor l is a conveyor equipped with a conveyor belt 11 that supports the text S and runs in the center of the conveyance surface of the frame. (The side will be explained as rear and the downstream side will be explained as front.) It is wound around a sprocket 12 and an idler 13 that are supported by a. The rotation shaft of the sprocket 12 is provided with a drive gear 14 for driving the rotation shaft within a gear box 4 attached to the right side of the frame. Note that the drive system for this drive gear will be described later.

A pair of chain conveyors 2 are arranged in parallel on both sides of the transport conveyor 1, and these chains 21 are provided with a plurality of chains (two in each case in the illustrated example) at a pitch corresponding to the length of the printed books S. ) lugs 22 are attached. Each lug 22 is wedge-shaped with its rear side upright and its front side inclined. The chain 21 meshes with a chain sprocket 23 and an idle gear 24 supported at the front and rear of the frame. Chain sprocket 23 is a gear that drives chain 21 and is configured to have a smaller diameter than sprocket 12. An idle gear 25 is supported immediately behind the chain sprocket 23, and cooperates with the rear idle gear 24 to maintain the running surface level of the lug 22. The rotation shaft of this chain sprocket 23 is provided with a drive gear 26 for driving the rotation shaft within a gear box 4 attached to the right side of the frame. Note that the drive system of this drive gear will also be described later.

In front of the transport conveyor 1, there are provided delivery rollers 3 which are driven at a lower speed than the chain conveyor 2 and cooperate with the nip rollers to nip and send out the text S from above and below.

A drive gear 31 that drives the rotating shaft of the delivery roller 3 is also arranged in the gear box 4 on the right side of the frame.

Guides 5 for guiding both sides of the text S are attached to both sides of the conveyance surface of the frame, and furthermore, three nip rollers are provided at the top of the conveyance belt 11 supported by a bracket attached to the left side of the frame. ing. The rear nip roller 6 is for decelerating the main text that is fed in, and the middle nip roller 7 is a roller that is installed at a slight inclination with respect to the direction of movement in order to align the widthwise position of the main text S after wrapping. The text S is horizontally banded and advanced so as to be pressed against the guide 5 on one side, and the front nip roller 8 is used to send the text to the text feed conveyor C of the cover pasting machine.

FIG. 2 is a block diagram showing the drive system of this device. As shown in the figure, the drive system of this device is connected to the output shaft 41 for driving the text feed conveyor of the cover pasting machine.
The rotation of the output shaft is transmitted to the sprocket 12, the sprocket gear 23, and the drive gears 14, 26, and 31 of the delivery roller 3 by appropriate means. Note that the text feed conveyor C of the cover pasting machine is not driven directly from the text feed conveyor drive output shaft of the same pasting machine, but is driven from the delivery roller shaft of the reverse wrap device A via a chain (not shown). .

Next, the operation of the reverse wrap device configured as described above will be explained with reference to the operation explanatory diagram of FIG. 3. In addition, to illustrate the operating speed in this device, the conveyor belt 11 is 800 mm/sec, and the lug chain 21 is 800 mm/sec.
is 500mm/see and the peripheral speed of delivery roller 3 is 300m
m/sec. In this device, as shown in Fig. 3 (al.
The reverse wrap operation is performed in the steps shown in ~(e).

That is, (a) the text S is sent from the crushing section B of the sewing machine device to this device at high speed (approximately 1300 mm/5ec).

(b) Then, the main text S1 is placed on the conveyor belt ll,
It is sandwiched between the conveyor belt 11 and the nip roller 6 and is decelerated to the speed of the conveyor belt, and eventually catches up with the lug 22 of the lug chain running at a slower speed than the lug chain, and conveys with its tip abutting the upright surface of the lug 22. It runs at the advancing speed of the lug 22 while sliding on the belt 11.

On the other hand, since the preceding main text S is sandwiched between the delivery roller 3 and the nip roller 8 and is moving at a lower speed, the inclination of the lug 22 increases as its leading edge approaches the rear end of the preceding main text S. Lift up the rear end of the main text S, which has a leading face, and slip under it.

(C) As the lug 22 slips below the preceding text S, the following text S1 gradually slips in from its tip, and at this time, the leftward pressure received from the nip roller 7 is caused by the force It is pressed against the guide 5, its widthwise position is corrected, and it advances while maintaining that state.

(d) Then, the lug 22 gradually begins to escape downward after passing the idle gear 25 position, and when the main body S1 has been wrapped by a predetermined amount, the tip reaches the delivery roller 3 and simultaneously sinks under the conveying surface, Release the engagement state with the tip of the main text S1.

(e) The main text S1 whose tip has reached the delivery roller 3 is now held between the main text S preceding the delivery roller 3 and the nip roller 8 and runs at the delivery speed, and eventually reaches the cover pasting machine. Move to text feed conveyor C.

In this way, according to the reverse wrapping device A of the above-described embodiment, the main text S, which is conveyed from the crushing section B of the sewing machine and whose positions in the width direction are uneven, is wrapped into a reverse valve state with the positions in the width direction aligned. and can be transferred to the text feed conveyor C of the cover pasting machine.

The present invention has been described above by taking the example of supplying passbook text to a cover pasting machine, but the present invention is not limited to the above-described embodiments, and can be handled within the scope of the claims. It goes without saying that the invention can be implemented by variously modifying the object and specific configuration.

〔Effect of the invention〕

The method of the present invention described above wraps the printing books conveyed one by one from the previous process in a reverse valve state and sends them to the next process. When the front end of the book is inserted, the rear end of the preceding book is pushed up in synchronization with the movement of the front end of the following book, so there is no interference between the ends of both books, and the reversing valve is This has the effect of reliably wrapping the state.

Furthermore, the apparatus of the present invention is provided with a conveyor that supports and conveys the printed books, a chain conveyor that is driven at a lower speed than the conveyor, and delivery rollers that send out the printed books while being driven at a lower speed than the chain conveyor. Therefore, by distributing the speed of each of these means, it is possible to reverse wrap the printed book without requiring special synchronization means or sensing means, and it also has the effect of being able to respond to changes in operating speed. It has the characteristics of being excellent.
