Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a three-dimensional multi-shelf transport device for cooling and drying books in a bookbinding process.

Conventional technology Conventionally, books discharged from a perfect binding machine are placed on their side, stacked in a certain number by a stacker device, and a long flat conveyor is installed in the factory and run for 2 to 3 minutes in order to cool and solidify the books. It was then cooled and dried.

In recent years, the speed of perfect binding machines has continued to increase, reaching from 6,000 books per hour to 13,000 books per hour. A three-way cutter is usually placed behind this perfect binding machine, and the book from the previous process is finished cut during the flow process, but the maximum thickness that the three-way cutter can cut at one time is usually 100 to 120 mm. Yes, 45 per minute
In order to increase the cutting efficiency due to the speed of about 100 times, and to save the required length of the cooling and drying conveyor, a stacker is used at the discharge section of the perfect binding machine.
The sheets are stacked to a height of ~120 mm, and as shown in Figure 1, they are passed slowly on a long flat conveyor and automatically fed into a three-sided cutting machine.

Problems to be Solved by the Invention In the conventional general bookbinding process, adhesive is sprayed on the part corresponding to the spine of the book, and the folded printed sheets that make up the book are fixed together, and at the same time the cover is attached to the spine of the book. During the modern high-speed wireless binding flow production process, electric heat, high frequency or gas heating, etc. are used to melt or solidify the adhesive.

For this reason, the spine of the book that is automatically discharged from the bookbinding machine is extremely hot, and the sprayed adhesive has not sufficiently cooled and solidified, making it difficult to immediately move on to the next finishing process, which is the three-sided cutting process. It was hot.

In order to cool and solidify this, a long flat conveyor was installed in the factory and run for 2 to 3 minutes to cool and dry, but the space occupied by this long flat conveyor was used by the wireless binding machine. It is increasing with the speed increase of 20 to 30 m.
In the bookbinding industry, which is an urban industry, the cost of floor space is extremely high.

Moreover, running a long conveyor around the factory greatly impedes the transportation of materials and work efficiency, and even if a conveyor that runs overhead is used, for example, it is not possible to achieve much savings, and on the contrary, other costs are reduced. This caused problems.

SUMMARY OF THE INVENTION The present invention was made to solve the above-mentioned problems, and consists of suspending a receiving shelf board on an endless chain suspended from sprockets arranged at arbitrary intervals, and connecting the receiving shelf board to a continuous or continuous chain of sprockets. Intermittent drive allows it to rotate in the same direction while keeping it horizontal, and a pile of books stacked from the outside is pushed onto the receiving shelf board, or a pile of books that have completed one cycle is pushed out from the receiving shelf board. In order to reduce the floor space occupied by the cooling and drying transport equipment to at least one-fifth of the conventional space, the three-dimensional space can be maximized, and the transport of materials and work efficiency can be improved. An object of the present invention is to provide a three-dimensional multi-shelf transport device for cooling and drying books.

The device 11 is provided with an extrusion device 13 on the discharge conveyor 10,
A stack of books 12 stacked from the outside is pushed onto the shelf board 5, or a stack of books 12 that has completed one circulation is pushed out from above the shelf board 5. .

Function The present invention has the above configuration, so that each receiving shelf board 5 moves downward on the front side, moves upward on the rear side, and circulates around the upper and lower sprocket pair 1, 2 continuously or intermittently.

First, a predetermined number of piles 12 of books carried onto the entrance conveyor 9 are stopped by a stopper, and then lined up in a line to wait. As soon as a predetermined number of books passes through the counter gate in front of the entrance conveyor 9, the gate is activated and the following stack of books 12
intrusion is prevented.

As mentioned above, the stack of books 12 waiting to be lined up is placed on the shelf board 5.
responds to the continuous or intermittent drive of sprocket pairs 1 and 2, and at the moment when it stops, it is pushed all at once onto the receiving shelf board 5 by the pushing device 11, and then the gate at the front of the entrance conveyor 9 opens, and the next A predetermined number of piles 12 of books are carried onto the conveyor 9.

As mentioned above, as soon as the receiving shelf 5 comes to rest, the discharge conveyor 10 provided above the entrance conveyor 9
At the top, the piles 12 of books on the receiving shelf 5 that have already been circulated through the device, cooled and dried are extruded from the inside by the extrusion device 13 all at once, and run away in the direction of the predetermined next process.

When the pushing and extrusion into the receiving shelf board 5 is completed, the sprocket pair 1 and 2 are driven, the receiving shelf board 5 moves rapidly, and when it comes to rest again, the above-mentioned process is repeated. In this case, the distance between the conveyors 9 and 10 at the entrance and discharge sections is equal to the interval between the receiving shelves 5, and the resting point of the receiving shelf 5 is at the same level as the entrance and discharge conveyors 9 and 10. No explanation required.

The sequence and speed of the operation of each part are controlled by a well-known electrical control method, and are carried out continuously and repeatedly in a fully automatic manner.

If the number of book piles 12 to be introduced into the entrance section is less than a predetermined number or interrupted, a selection switch determines whether the device continues the sequence or stops and waits for the arrival of book piles 12. You can choose.

Next, when the receiving shelf board 5 with the presser plate 20 which is currently holding down and pressurizing the pile of books 12 approaches the book ejection station during its descending cycle, the holding plate 5 is moved by the lifting claw 27 waiting in a fixed position. 20 is in the lifted state, and the receiving shelf board 5 continues the lowering cycle while leaving the presser plate 20 at the position of the lifting claw 27.

The locking claw 22, which is attached to the side plate 23 and descends as the receiving shelf board 5 descends, passes the stationary lifting claw 27 and comes to the lower side of the holding plate 20, and at the same time, the locking claw 22 is attached to the lifting claw 27. The mounted roller 28 is pushed by the fixed cam 21, and the lifting claw 27 is moved to the fulcrum 32.
The holding plate 20 is opened from the center, the holding plate 20 is removed from the lifting claw 27, and is in a state where it can be received by the locking claw 22 on the lower side, and then the receiving shelf board 5 stops.

The receiving shelf board 5 stops at the book ejection station,
Once the pile of books 12 has been ejected, the shelf board 5 moves downward again, and a new pile of books 12 is placed at the next station.
However, during this time, the holding plate 20 remains lifted by the locking claw 22.

As soon as the receiving shelf board 5 receives a new book and moves further down by continuous or intermittent movement, the roller 30 attached to the lever 29 waiting in the fixed position hits the pin 31 in the locking pawl 22 and locks it. The claw 22 is tilted around the fulcrum of the connecting shaft 25, and the presser plate 20 is attached to the stack of books 12.
fall on top of.

In this way, the presser plate 20 circulates through the device of the present invention while pressing the stack of books 12 with its own weight, is lifted just before the book ejection station, and is dropped immediately after the book insertion station, and the process is automatically repeated. It turns out.

At the end of the production process, a new pile of books 12 is placed on the receiving shelf 5.
If the lever 29 is automatically retracted by a well-known electromagnetic method when the latch is no longer supplied, the presser plate 20 will move forward while being supported by the locking pawl 22.
There will be no problem when work resumes.

Embodiment The present invention will be explained below based on an embodiment shown in the figures.A pair of upper and lower sprockets 1 and 2 are installed on a conveying device at different heights on both left and right sides, that is, with their installation positions shifted. Endless chains 3 and 4 of equal length are suspended from sprocket pairs 1 and 2, respectively.

A plurality of concave receiving shelf boards 5 are arranged at equal intervals around the entire circumference so as to bridge between the left and right chains 3 and 4.

Further, two sets of levers 6, 7 are provided at intervals equal to the distance between the receiving shelf boards 5 over the entire length of each chain 3, 4.
are rotatably connected, and one lever 6 on the left and right,
Each receiving shelf board 5 is held by 7.

Above, on the outer side of both end surfaces of each receiving shelf board 5, upper and lower 2
A total of four connecting bosses 8 are provided at relative positions, and the levers 6 on one chain 3 side are all rotated to the upper boss 8, and the levers 7 on the other chain 4 side are all rotated to the lower boss 8. freely connected.

The boss 8 is provided with a bearing roller guide 15, and the guide 15 moves up and down in cam guides 14 provided near both sides of the shelf board 5 to stably hold the shelf board 5 and move it up and down. I'm letting you do it.

When the left and right sprockets 1 and 2 are simultaneously driven by a known method (not shown), all the receiving shelf plates 5 connected to the chains 3 and 4 move in the sprocket driving direction while remaining horizontal.

Further, in the front of the conveyance device, there is an entrance conveyor 9 that sends a plurality of stacks of books 12 to the receiving shelf board 5, and a plurality of stacks of books 12 that have been circulated through the device and have been cooled and dried. Discharge conveyors 10 that receive the liquid from the receiving shelf board 5 are provided vertically adjacent to each other.

Further, there is also a pushing device 11 that operates in a known manner to push the stack of books 12 onto the receiving shelf board 5 from above the entrance conveyor 9 all at once, and a pushing device 11 that operates in a known manner to push the stack of books 12 on the receiving shelf board 5 all at once onto the discharge conveyor 10. An extrusion device 13, which is also driven in a known manner, is provided for extrusion from the inside.

Immediately before the entrance conveyor 9, the piles 12 of books continuously flowing from the previous process are calculated, and as soon as a predetermined number of piles 12 enter the entrance conveyor 9, they prevent the following piles 12 of books from entering. There are counters and gates that operate by known photoelectric and pneumatic methods.

Further, at the end of the entrance conveyor 9, a stopper is provided for stopping the stacks 12 of books carried onto the conveyor 9 and arranging them in a line.

Next, when the receiving shelf board 5 rotates around the upper and lower sprocket pair 1 and 2, in a normal device, when the receiving shelf board 5 moves from vertical motion to rotational motion centered on the sprocket, the receiving shelf boards collide with each other and cause interference. Therefore, it is necessary to set a wide interval between each receiving shelf board in advance, and the number of receiving shelf boards that can be provided within the effective height range is greatly limited.

However, in the device of the present invention, the left and right sprocket pairs 1 and 2 are provided at different heights, so that the receiving shelf board 5 changes from vertical movement to sprocket pairs 1 and 2.
2, only the catch shelf plate 5 located in the sprocket rotation part is moved adjacently by the action of the levers 6, 7 that connect the chains 3, 4 and the boss 8 provided on the catch shelf plate 5. This is advantageous because the shelf plates 5 are pulled apart from each other, temporarily increasing the distance between them, and can smoothly rotate while maintaining their horizontal position without colliding with each other.

Further, in the present invention, the connecting portions between the chains 3, 4 and the levers 6, 7, and the connecting portions between the levers 6, 7 and each receiving shelf board 5 are formed to be rotatable, and the connecting boss 8 of the receiving shelf board 5 has a , a bearing roller guide 15 is provided, and this bearing roller guide 15 runs along the cam guide 14 in the vertical movement section of the receiving shelf board 5. Furthermore, since the chains 3 and 4 themselves are driven vertically along the cam guide 14, there is little vibration in the endless chains 3 and 4, and there is almost no vibration in the receiving shelf board 5. 12 piles of books will not fall down.

Furthermore, since the inlet and discharge parts are provided above and below adjacent to the front of the device, floor space can be saved, and all of the receiving shelves 5 of the device of the present invention can be used at all times.
Since the book stack 12 is filled with books and circulated, cooling and drying can be carried out efficiently without waste.

Furthermore, when the rotating part of the receiving shelf board 5 of the apparatus of the present invention is covered with a compact box-shaped cover 16, except for the openings of the inlet and discharge parts, cold air can also be sent into the cover 16, thereby increasing the cooling and drying speed. It is also possible to increase

Next, what is shown in FIGS. 4 to 6 shows an embodiment for attaching a presser plate to press the stack of books from above on the upper side of each receiving shelf board. A holding plate 20 made of a heavy material such as a piece of iron plate is placed on the stack of books 12, and pressurizes the stack of books 12 with its own weight.

Small fixed cams 2 are provided on the outside of both sides of each shelf board 5.
Two locking claws 1 and two locking claws 22 are installed in parallel, and the tips of the locking claws 22 peek into the interior of the receiving shelf board 5 through an opening 24 provided in the side plate 23.

The two locking claws 22 are rotatably attached to the side plate 23 by a mounting body 26 via a connecting shaft 25. Further, the front and rear width of the presser plate 20 is slightly wider than the front and rear width of the side plate 23, and the presser plate 20 projects from the front and rear of the receiving shelf board 5.

A support frame 33 is provided on both sides of each receiving shelf board 5, and a lifting claw 27 is rotatably attached to the support frame 33 via an attachment frame 34. A lever 29 provided with a roller 30 is attached below the lifting claw 27 to a support frame 33 so as to be movable forward and backward by a known electromagnetic method.

In addition, 28 in the figure is a roller provided on the lifting claw 27,
31 is a pin provided on the locking claw 22, 32 is a fulcrum, 3
5 is a spring.

Effects of the Invention Therefore, according to the present invention, since the intervals between the receiving shelf boards are closely provided, the effective three-dimensional space can be utilized to the maximum.

Next, when the catch shelf rotates around the pair of upper and lower sprockets, in a normal device, when transitioning from vertical motion to rotational motion around the sprocket, the catch shelf boards collide and interfere with each other.
It is necessary to provide a wide interval between the respective receiving shelves in advance, and the number of receiving shelves that can be provided within the effective height range is greatly limited.

However, in the device of the present invention, the left and right sprockets are provided at different heights, so when the catch shelf plate transitions from vertical movement to rotational movement around the sprocket, only the catch shelf plate located in the sprocket rotation part moves. is pulled away from the adjacent shelf board by the action of the lever that connects the chain and the boss provided on the shelf board, and the gap temporarily increases, allowing them to rotate smoothly while maintaining their horizontal position without colliding with each other. This is advantageous because it can be done.

Further, in the present invention, the connecting portion between the chain and the lever, and the connecting portion between the lever and each shelf board are formed to be rotatable, and a bearing roller guide is provided on the connecting boss of the receiving shelf board, so that the connecting part between the chain and the lever and the connecting part between the lever and each receiving shelf board are rotatable. In the vertical movement section, this bearing roller guide runs along the cam guide. In addition, since the chain itself is driven vertically along the cam guide, there is little vibration of the endless chain, and there is almost no vibration of the receiving shelf, which prevents the pile of books stacked on the receiving shelf from falling down. Never.

Furthermore, since the inlet and discharge parts are provided above and below adjacent to the front, floor space can be saved, and all the shelves of the device of the present invention are constantly filled with piles of books and circulated. Therefore, cooling and drying can be performed efficiently without waste.

In addition, since multiple stacks of books are arranged in a line closely adjacent to each other and loaded on a receiving shelf, the unit area is smaller than when the books are conveyed on a long flat conveyor line that runs on a flat surface. The density of the upper book pile is high, which saves a lot of space, and the operating speed of the device of the present invention can be arbitrarily adjusted according to the speed of the production line.

In addition, in the case of a conventional long flat conveyor, the weight of the pile of books causes large friction between the belt and the conveyor support plate, requiring a considerable amount of driving energy, but in the case of the device of the present invention, the weight of the books is It is economical because it is distributed to the rear side and requires very little driving energy.

Furthermore, having a presser plate on each shelf board that presses the pile of books with its own weight gives calmness to books that are rough just after a cover has been attached, and is effective in producing high-quality books.

Especially if the book is light, has a very slippery cover, or has a significantly uneven thickness, there is a risk that the stack of books will collapse even with the slightest vibration, so it is best to avoid adding weight from above. is preferred.

Furthermore, for books that require linear glue to be applied to the edge of the cover in addition to the spine, the cover of the book that is stacked on top often rises and does not adhere properly to the main text. Effective for proper adhesion.
