Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a three-dimensional multi-shelf transport device for cooling and drying books.

In the conventional general bookbinding process, modern high-speed wireless bookbinding involves spraying adhesive on the part corresponding to the spine of the book, fixing the folded printed papers that make up the tree, and at the same time adding the cover to the spine of the tree. During the flow production process, electric heat, high frequency, 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. there were.

Therefore, the books discharged from the perfect binding machine are usually placed on their side, stacked in a certain number by a stacker, 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. .

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-sided cutting machine is usually placed behind this perfect binding machine.
The wood from the previous process is finished and cut within about -L,
The maximum thickness that can be cut at one time with a three-sided cutting machine is usually 100~
120+u+, and the cutting speed is approximately 45 times per minute.In order to increase the cutting efficiency and save the length of the necessary cooling and drying conveyor, a stacker is used at the discharge section of the perfect binding machine to stack the sheets at a height of 100 to 12 o1. As shown in FIG. 1, the material is allowed to flow slowly on a long flat conveyor and is automatically fed into a three-sided cutting machine.

The space occupied by this long flat conveyor is increasing as the speed of the perfect binder increases, reaching 20 to 30 meters, and the cost of floor space is extremely high in the bookbinding industry, which is an urban industry. Moreover,
Routing long conveyors within a factory greatly impedes the transportation of materials and work efficiency. For this reason, for example, even if a conveyor running overhead is used, it is not possible to achieve much savings, and on the contrary, it causes other problems.

As mentioned above, the purpose of the present invention is to maximize the three-dimensional space so that the floor space occupied by the cooling and drying sub conveyor can be reduced to a minimum of 175 mm or less compared to the conventional one, and to improve material transportation and workability. The aim is to

Another object of the present invention is to attach a presser plate to the upper side of each receiving shelf board for pressurizing the pile of books from above, to ensure smooth transportation of the pile of books and to ensure the gluing of the wood. It is.

The present invention will be explained based on the embodiments shown in the figures below.
The transport device has a pair of upper and lower sprockets 1 and 2 installed at different heights on both the left and right sides, and endless chains 3 and 4 of equal length are attached to the pair of sprockets 1 and 2, respectively.
is suspended. 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 3.4.

In addition, two sets of levers 6.7 are rotatably connected at intervals equal to the distance between the receiving shelf boards 5 over the entire length of each chain 3.4, and one set of levers 6.7 on the left and right sides Each receiving shelf board 5 is held.

A total of four connecting bosses 8, two on the upper and lower sides, are provided at relative positions on the outside of both end faces of each receiving shelf board 5, and all the levers 6 on one chain 3 side are on the upper boss, and the levers 6 on the other side are connected to the upper boss. The levers 7 on the fourth side are all rotatably connected to the lower boss.

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 receiving shelf board 5 to stably hold the receiving shelf board 5 and move it up and down. ing.

When the left and right sprockets 1.2 are simultaneously driven by a known method (not shown), all of the catch shelves 5 connected to the chain 3.4 move in the sprocket driving direction while remaining horizontal.

Further, in front of the conveyance device, there is an entrance conveyor 9 for feeding a plurality of stacked wood piles 12 to the receiving shelf board 5, and a plurality of wood piles 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. Additionally, there is a pushing device 11 that operates in a known manner to push the pile of wood 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 pile of wood 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, there is a counter and a counter that calculates the piles of books 12 that continuously flow from the previous process, and prevent the following piles from entering as soon as a predetermined number of piles enter the entrance conveyor 9. There are gates, all of which are operated by known photoelectric and pneumatic methods.

Furthermore, a stopper is provided at the end of the entrance conveyor 9 to stop the pile of wood 12 carried onto the conveyor and align it to the - line.

Since the present invention has the above-mentioned configuration, each receiving shelf board 5 moves downward on the front side, moves upward on the back side, and circulates around the upper and lower sprocket pairs 1 and 2 continuously or intermittently.

First, a predetermined number of wood piles 12 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 has passed through the counter gate in front of the entrance conveyor 9, the gate is activated and subsequent stacks 12 of books are prevented from entering.

As mentioned above, the stack of books 12 waiting to be lined up is pushed onto the shelf board 5 at once by the pushing device 11 at the moment the shelf board 5 descends and stops in response to the continuous or intermittent drive of the tin rocket pairs 1 and 2. Then, the gate at the front of the entrance conveyor 9 is opened, and the next stack of books 12 is carried into the conveyor 9-[1 in a predetermined number.

As mentioned above, as soon as the receiving shelf board 5 comes to rest, the entrance conveyor 9
On the discharge conveyor 10 installed at the top of the machine, the piles of wood 12 on the receiving shelf board 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 are placed in a fixed position. Runs away in the direction of the next process.

When the pushing and pushing into the receiving shelf board 5 is completed, the sprocket pairs l and 2
is driven, the receiving shelf board 5 moves rapidly, and when it comes to rest again, the above-mentioned process is repeated. In this case, each conveyor 9 at the inlet section and the discharge section. The interval of lO and the interval of the receiving shelf board 5 are equal,
The stationary parts of the receiving shelf board 5 are the entrance and the discharge conveyor 9.1.
The fact that it is on the same level as 0 does not require any explanation.

The sea fence and speed of the operation of each part are controlled by a well-known electrical control method, and are continuously and repeatedly performed fully automatically.

If the number of piles of wood that should flow into the entrance part is less than a predetermined number or is interrupted, the selection switch allows the device to select whether to continue sea fencing or to stop and wait for the arrival of the pile of books. I can do it.

Next, what is shown in FIGS. 4 to 6 shows an embodiment for attaching a presser plate that presses a pile of wood from above to the upper side of each receiving shelf board, and is arranged on each receiving shelf board 5. A holding plate 20 made of a heavy material such as a piece of iron plate is placed on the wood pile 12, and pressurizes the wood pile 12 with its own weight.

Two small fixed cams 21 and two locking claws 22 are installed in parallel on the outside of both sides of each receiving shelf board 5, and the tips of the locking claws 22 are connected to the opening holes 22 provided in the side panels 23.
It looks into the inside of the receiving shelf board 5. The two locking claws 22 are rotatably attached to the side plate 23 by a mounting body 26 via a connecting shaft 25. Furthermore, presser plate 2
The longitudinal width of 0 is configured to be wider than the longitudinal width of the side plate 23, and the holding plate 20 projects from the front and rear of the receiving shelf plate 5.

A support frame 33 is provided on both sides of each shelf board 5, and a support frame 33 is provided with a holding claw 27 via a mounting frame 34.
is rotatably mounted. Below the lifting claw 27, rollers 30 are provided, and thousands of rollers 30 are mounted on the support frame 33 so as to be movable forward and backward by a known electromagnetic method.

In the figure, 28 is a roller provided on the lifting claw 27, 31 is a pin provided on the locking claw 22, 32 is a fulcrum, and 35 is a spring.

When the receiving shelf board 5 with the presser plate 20 which is currently holding down and applying pressure to the pile of wood 12 approaches the book ejection station during its descending cycle, the presser plate 20 is held down by the lifting claw 27 waiting in the fixed position. In the lifted state, the receiving shelf board 5 continues the descending cycle while leaving the holding 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 installed roller 28 is the fixed cam 2
1, the lifting claw 27 opens around the fulcrum 32, the presser plate 20 comes off the lifting claw 27, and the locking claw 2 on the lower side opens.
2, the receiving shelf board 5 becomes ready to be received, and then the receiving shelf board 5 stops. When the receiving shelf board 5 stops at the wood discharging station and the wood pile 12 is ejected, the receiving shelf board 5 moves downward again and receives a new wood pile 12 at the next station, but 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 tree and moves further down in continuous or intermittent motion, the roller 30 attached to the lever 29 waiting in the fixed position hits the bin 31 in the locking pawl 22,
The locking pawl 22 is tilted about the fulcrum of the connecting shaft 25, and the holding plate 20 falls onto the pile of wood 12.

In this way, the presser plate 20 automatically circulates through the device of the present invention while pressurizing the pile of wood 12 with its own weight, is lifted just before the tree discharge station, and is dropped immediately after the tree insertion stage. will be repeated.

At the end of the production process, when a new pile of wood 12 is no longer supplied to the receiving shelf board 5, the lever 29 is automatically retracted by a known electromagnetic method, so that the presser board 20 is engaged with the locking pawl 22. The work progresses with support, and there is no problem when work resumes.

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, the catch shelves collide and interfere with each other when transitioning from vertical motion to rotational motion centered on the sprocket. It is necessary to leave a wide gap between the receiving shelves in advance, which greatly limits the number of receiving shelves that can be installed within the effective height range. 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 centered on the sprocket, only the catch shelf plate located in the sprocket rotating part 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, the gap temporarily increases, and the chains 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 15 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 shelf board are rotatable. In the vertical motion section, this bearing roller guide 15 runs along the cam guide 14. 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 shelf board, so the pile of wood on the shelf board will not collapse. do not have.

Furthermore, since the inlet and discharge parts are provided above and below the front part adjacent to the front part, it is possible to save floor space and all the receiving shelves of the present invention device are always filled with piles of wood and circulated. Therefore, cooling and drying can be performed efficiently without waste.

Furthermore, if the rotating part of the receiving shelf board of the device 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, increasing the speed of cooling and drying. You can also do that.

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

In the case of a conventional long flat conveyor, 1. The weight of the pile of trees causes a lot of friction between the belt and the conveyor support plate, which requires a considerable amount of driving energy, but in the case of the device of the present invention, the weight of the books is distributed between the front side and the back side. It is economical because it requires very little driving energy.

Furthermore, having a presser plate on each shelf board that presses the pile of wood 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 wood.

Especially if the book is made of light wood, 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 do not add weight from above. is preferred.

Furthermore, for books that have line drawings applied to the edge of the cover in addition to the spine, the wooden cover that is stacked on top often stands out and does not adhere properly to the main text. It has an adhesive effect.
