Description

Detailed Description of the Invention (Field of Industrial Application) The present invention automatically inserts insert paper pieces used for sales slips or order slips into books displayed in a bookstore by inserting them between the middle few pages of a bound book. Concerning mechanical devices that are set in

(Prior Art) In the past, inserting paper pieces into a bound book was mainly done manually. That is, the insertion piece, which has been folded in half in advance, is inserted into the middle several pages of the opened bound book, but this operation is extremely labor-intensive and is therefore inefficient.

Therefore, as a means of automating this process, we opened a bound book with its spine facing down to the left and right with several sheets in the center standing upright, and inserted the pieces of paper into the area through which the upright portions passed and placed the pieces of paper in a horizontal position. It has been proposed to leave the piece of paper facing up, and as it passes, fold the piece of paper in half from the middle, insert it so that it is exposed to both sides of this upright part, and then close the bound book again. .

(Problems to be Solved by the Invention) By the way, as a conventional method for inserting pieces of paper into a bound book, manual work is extremely inefficient, and conventionally proposed automatic devices do not allow the back of the bound book to be inserted. Since it is unfolded downward, it is necessary for this unfolded state to pass under the inserted piece of paper placed horizontally with the upright part left fully open to the left and right, and it is necessary to close it again. For this reason, it was necessary to lengthen the travel path for the bound book to allow this unfolding and closing.1 This had the disadvantage that the overall length of the processing machine was long, resulting in a long rope. According to the conventional method, since the book must be opened with the back facing down and a portion of the book must remain upright, the back needs to be stabilized, which has the disadvantage that it cannot be applied to thin books.

Therefore, it is an object of the present invention to provide an automatic insertion device that can reduce the bulk of the mechanical device and can be applied to thin bound books, and that can perform efficient work.

(Means for Solving the Problems) Therefore, in the present invention, first, a device configuration means is adopted that processes the bound books in the horizontal position with the bound book lying in its thickness direction, and some of the bound books are half-opened in the horizontal position. A slit fitting is provided to hold the leaf, a discontinuous part is provided on this fitting, a piece of paper is placed facing the discontinuous position, and a piece of paper is placed facing the discontinuous position. It is configured to obtain a sandwiched state while being pushed in using the subsequent slit metal fittings in the latter half.

(Function) According to the present invention, since the bound book is transported in a horizontal position,
During transport, the bound book is transferred stably under stress by a means such as pinching the back of the bound book. During this time, the bound book is held by the slit metal fittings and left in a half-open state with a few separated leaf portions remaining. (Specifically, the teacher's part held between the slit fittings and the state along both outside sides of the fittings) are maintained.

The inserted piece of paper waiting in the discontinuous part of the slit fitting is
It hits the edge of the bound book that has moved in the half-open state, and is pushed into the slit fitting in the latter half along with the bound book. The second half of the slit fittings act to push the invading paper pieces into both sides of the several-leaf section of the bound book, which also intrudes, while turning them in a curved manner.

As a result, the inserted paper piece is forcefully inserted into the small gap between the pair of parallel flat plates of the slit fitting. Then, the bound book passes through the slit fitting and closes naturally due to its own weight from the half-open state, thus completing the pinching operation.

(Embodiments) Preferred embodiments of the apparatus of the present invention will be described below.

Fig. 1 is a perspective view showing the configuration of the main parts of the device of the present invention, and Fig. 2 is a perspective view showing the feeding mechanism for inserting paper pieces in the device of the present invention. Consists of an endless belt, with two protrusions at the
is installed.

This protrusion 2 has a height that is sufficiently low for the thickness of a book 3 stacked flat on the mounting table 1 with the backs aligned to one side, so that when the endless belt is activated, the height of the bound book 3 is sufficiently low. Pass through the regulating rod 4 that hangs down from the tip area to a height corresponding to the thickness of one book from the base surface, and while pushing the rear end of one book at the bottom of the stacked books 3, move the next receiver. Send it towards table 5.

A chain belt 6 and a guide rail 7 are arranged parallel to each other along the edge of one side of the receiving table 5, and the delivered bound book 3 has its back connected to the chain belt 6. It is inserted between the guide rail 7 and is transferred while sliding on the pedestal 5.

A slit fitting 8 is placed on the receiving table 5 on which the bound book 3 moves along the moving range of the open end of the bound book 3, floating from the upper surface of the table 5. That is, this slit fitting 8 is made of two parallel plates arranged in parallel with a small gap between them, specifically a metal plate bent into a U-shaped cross section, and is made of a metal plate bent into a U-shaped cross section.
The tip portion in the direction in which the binding book 3 moves is formed into an inclined surface 9 that is cut diagonally from the opening of the bound book 3 toward the back, and
At the tip of the surface 9, a separation fitting 10 made of particularly thin blades and having a slit groove structure made of two parallel plates is attached.

While the slit fitting 8 is placed on the pedestal 5, it has a rear slit fitting 11 with a partially cut discontinuous portion interposed therebetween.

Further, a cut groove 12 is provided in the pedestal 5 at this discontinuous portion, and an insert piece of paper 13 is vertically dropped from above the pedestal 5 through the cut groove 12, so that the middle part of the paper piece 13 meets the gap of the slit fitting 8. Place it on the bottom plate metal fitting 14 so as to face the continuous end, and make it stand up.

This inserted piece of paper 13 is inserted into the stocker 1 as shown in FIG.
5, and the lower end of the frame of the stocker 15 is supported and held by a claw-like engaging part 16 that slightly protrudes inward. An air valve mechanism that has a cylinder 17 and has several intake holes 18 arranged in tandem on its outer circumferential surface, and takes in air from the vent hole 18 only during a substantially half rotation range including a state where the row of intake holes 18 is in a position directly above. It is connected to an electric pump (not shown) under the control of.

Furthermore, this rotary cylinder 17 is supported by a support rod 19 that moves up and down at a constant period in synchronization with the rotational movement of the rotary cylinder 17.

That is, when the cylinder 17 rotates and the row of intake holes 18 reaches the position directly above it, the support rod 19 is also in the uppermost position, and the outer peripheral surface of the core portion 17 is held in the stocker 15. When it comes into contact with the lower surface of the insert paper piece 13, the air intake hole 1
3 starts suction, and by the subsequent rotation of the rotary cylinder 17 and the downward movement of the support rod 19, one piece of inserted paper 13 is pulled away from the claw-like engaging part 16 of the stocker 15 and moved to the side of the cylinder 17. The intake operation is cut off when the core 17 rotates until the row of intake holes 18 reaches the position directly below it. The inserted paper piece 13, which has fallen away from the tube 17 due to its own weight, rides on the delivery roller 20 directly below it.

A suction hole 21 is also provided on the outer peripheral surface of the feed roller 20, and in synchronization with the operation of the roller 20, the fallen piece of paper 13 is attracted to the roller surface side by the suction force of the suction hole 21. , and send it out to the pinch roller 22 side.

At the time when the leading end of the inserted paper piece 13 that has been fed out is pinched between the feeding roller 20 and the pinch roller 22, the suction force of the feeding roller 20 to the intake hole 21 is cut off by the valve action, and after that, the pinch roller -22
By the pinching action, the inserted paper piece is sent to the upright position as described above. FIG. 3 shows the positional relationship between the transport path of the bound book 3 and the feeding of the inserted paper piece 13.

During the feeding of the inserted paper piece 13, the bound book 3 is transported along the receiving table 5, and its leading edge reaches the end region of the discontinuous part of the slit fitting 8, and by the subsequent transport,
The inserted paper piece 13 facing perpendicularly to this discontinuous part is pushed onto several sheets of the bound book 3 which is sandwiched between the slit fittings 8 and separated, and is moved to the next latter half of the slit fitting 11 by rolling it up. do.

In addition to the above-mentioned extrusion and separation of the binding book 3, this relationship is
This will be explained using the operation diagram shown in the figure.

That is, the upper part of FIG. 4 shows a side view of each main part of the movement of the binding book, and the lower part shows the corresponding positional relationship on the plane.

In the bound books 3 stacked on the mounting table 1 at the position (4) in Fig. 4, the bottom book is pushed out by the protrusion 2.
) reach the position. In this (B) position, the thin blade separation fitting 1
0 bites into the bound book 3 from the open end of the moving bound book 3,
Several leaves of the bound book 3 corresponding to between the slits of the metal fitting 10 are guided between the slits and then separated from the narrow leaf portion.

This separation fitting 10 has a slit gap that becomes slightly wider toward the rear, and is connected to the slit fitting 8, so that
When the bound book 3 is transferred to the position shown in FIG. With the narrow leaves of book 3 spread out, move to the next position (D) in the same figure.

(2) Once the bound book 3 has reached the position, the edge of the sheet is placed in the discontinuous portion of the slit fitting 8, and it comes into contact with the hanging insert paper piece 13, and then moves toward the slit fitting 11 in the latter half. Of course, at this time, due to the pinching of the discontinuous portion and the stiffness of the paper sheets of the binding book 3, there is no problem with folding, etc.
A movement is made from the slit fitting 10 to the slit fitting 11.

At the edge of the bound book 3 that has progressed to the slit fitting 11, the same figure @)
As shown in the figure, the inserted paper piece 13 is pushed by the edge of the slit metal fitting 11, and while being reversely curved at this part, as the binding book 3 is moved and pushed in, this reversely curved part is slid in a sequential manner. Roll it up along both sides of the separated leaves.

When the insertion by winding up the inserted paper piece 13 is completed and the bound book 3 passes through the area of the slit metal fitting 11, the bound book 3 that has been released from the separation and push-opening by the metal fitting 11 closes naturally under its own weight, and the inserted paper piece 13 is properly inserted in such a way as to sandwich the previous few separated leaves.

In addition, in the above-described apparatus of the present invention, the height position of the regulating rod 4 of the mounting table 1 and the guide rail 7 are adjusted depending on the thickness of the bound books 3 to be processed.
The position of the bottom plate metal fitting 14 is adjusted according to the clamping pressure of the slit fittings 10 and 11 from the holder 5, and the length of the inserted paper piece 13.In addition, the inserted paper piece 13 is a rotating tube. Since the paper is sent out with the front and back sides reversed by the operation in step 17, it is necessary to set the paper with the printed surface facing downward when storing it in the stocker 15.

(Effects of the Invention) As described above, according to the device of the present invention, by configuring the step of first stacking the bound books flat and then processing them in the horizontal position, it is possible to stack the bound books, and As the number of stacks decreases through processing, it is possible to stack them one after another, allowing continuous operation in automatic processing. In particular, the processing of bound books in the horizontal position in the apparatus of the present invention is advantageous in the following points. In other words, the bound book, which is held horizontally between the guide rail and the chain belt and fed forcefully and stably, can be separated into several pages by the slit metal fittings, and the book can be left in a half-open state with less penetration by the metal fittings. There is no need to fully open the bound book vertically as in the conventional device, and the process stroke for this opening operation can be made extremely short.As a result, the overall length of the device can be shortened and the device can be constructed to be small. can do. In addition, in the vertical position processing of bound books in conventional devices, the back of the bound book is stiff to maintain the vertical position, and it was not possible to process thin bound books, etc., but the present invention The horizontal position processing of the device allows processing of thin books, which is not possible with conventional devices.

As described above, the device of the present invention can reduce the bulk of the device configuration, expand the thickness and shape of bound books that can be processed, and improve work efficiency through continuous processing, making it suitable for practical use. It is extremely useful.
