Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a signature bundling pre-processing device, specifically, to bundle a large number of signatures discharged from a rotary press and bind them with bands. Pre-processing is carried out to make it easier to use, in other words, the signatures are stacked in a small bundle of a certain number of copies in what is called a stack, and then the folds are sequentially turned over so that the fold side occupies the opposite side. The present invention relates to a device for performing a pressing process.

It is more advantageous to pre-process the binding of signatures by piling them up in a pile than by arranging them one after the other in an upright manner, as it occupies less floor space. Furthermore, it is obvious that it is preferable that the device for accumulating small signature bundles, including the signature reversing device, be connected to the press device for stacking the signature stack via a stacking means for stacking the small signature bundles as a pre-process. be.

However, the implementation of said connections may depend on whether the stations for accumulating the signatures into bundles and the stations for pressing the stacks of signatures are economical in practice.
Whether these stations are actually economical or not will determine whether they are suitable for practical use.

Prior Art and Problems Theretofore, no signature binding pre-processing device for stacking signatures in a stack that satisfies the above-mentioned points has yet been developed.

Incidentally, until now, it has not been seen that the small signature stacking station has been improved so as to double as a station for preliminary pressing before the press processing by the machine that presses the small signature bundle, and when it comes to the signature stacking press machine, The only structure known is one in which the stack of signatures is pressed entirely on the top surface by a press plate, but this type of press does not effectively expel air between the signatures during pressing, resulting in poor press processing. is not suitable for practical use.

The invention disclosed in Japanese Unexamined Patent Application Publication No. 115211/1983 was proposed as a new stack of folded stack press apparatus. The device of this proposed invention includes a central pressing member for pressing an intermediate area of a stack of signatures, and a central pressing member that presses the left and right end areas of a stack of signatures, which is pivotally connected at one end to both left and right ends of the central pressing member. The central pressing member is attached to the lower cylinder of the telescopic pressing cylinder with a built-in coil spring, and the central pressing member is attached to the upper end of the upper cylinder of the pressing cylinder as a driving device. A bracket that is pressed down by an air cylinder plunger device is fixed, one end of a link that rotates the pressing member is connected with a pin to the tips of the left and right pressing members, and the other end of the link is connected to the bracket on the upper cylinder. It has a pin-coupled configuration.

However, in this proposal, after the center pressing member hits the stack of signatures due to the lowering of the telescopic push-down tube as the bracket is pushed down, the bracket is further moved against the lower tube of the telescopic push-down tube, that is, the central push member. On the other hand, by descending together with the upper cylinder of the push-down cylinder, the left and right pressing members are swiveled downward to press the pile of signatures. Therefore, in the proposed proposal,
If the center pressing member does not firmly press the middle area of the stack of signatures before pressing the left and right pressing members, the stack of signatures may have different heights at the left and right ends (folds). (For example, when the number of small bundles of signatures stacked is an odd number), when the left and right pressing members compress the ends of the stack of signatures, the stack of signatures is curved laterally.
In other words, the pressing process of the pile of signatures becomes defective.

In this proposal, the following restrictions must be met in order to ensure that the above-mentioned advance pressing of the central pressing member is performed.

As is well known to those skilled in the art, the stack of folds has a substantially concave intermediate region;
Before the left and right pressing members press the left and right ends of the stack of signatures, in order for the center pressing member to press the stack of signatures, the left and right pressing members must move upwards considerably relative to the center pressing member. It is necessary to take a tilted position. This means that the left and right pressing members have to pivot through a considerable angle in order to press the ends of the stack of signatures, and the telescopic push-down tube has to be shortened considerably. do. Thus,
The coil spring in the push-down tube must also be compressed fairly short.

Furthermore, in order to achieve the above pre-pressing of the central pressing member, the coil spring needs to be of a fairly strong spring. If,
If the spring is weak, the telescopic press-down tube will begin to shorten before the central pressing member is sufficiently pressed, and there is no guarantee that effective preliminary pressing of the central pressing member will be achieved.

Such strong coil springs are not economically available. Moreover, in order to compress a strong spring in a fairly short amount of time, the air cylinder/plunger device used as the driving device needs to be particularly large and have a high output.
This is also not something that can be obtained economically.

In other words, in order to ensure that the central pressing member is pressed first and then the left and right pressing members are pressed reliably, a particularly large and high-output air cylinder/plunger device must be used. It has not yet reached the point where the preceding press and subsequent press can be achieved economically.

Therefore, there is a big problem in putting the press device of the proposed invention into practical use, and even if a conventionally known small bundle stacking device is added to the press device as a pre-process, it is said to be far from practical. obtain.

It is an object of the present invention to economically realize a small signature stacking station including a signature reversing means and a signature pile stack press station, and to provide a signature pile stack means as a pre-process to the signature stack press station. An object of the present invention is to provide a signature bundling preprocessing device which can be used for the purpose of connecting signature small bundle accumulation stations through a signature bundle accumulation station.

Means for Solving the Problems The above objects of the present invention are achieved by an apparatus having the following configuration.

A small signature bundle accumulation station that stacks the signatures discharged one after another from a rotary press into a small bundle of a certain number of copies by an appropriate means, and a folding station that stacks the small bundle of signatures from the station into a small bundle of a certain number of copies by an appropriate means. The component includes a press station for pressing the stack of signatures, which is connected downstream to the signature small bundle stacking station via a stack stacking station, and the small signature bundle stacking station is connected to the signature stacking position and outside the signature stacking range. a signature stacking shelf that can be driven between the latter positions, a stopper that cooperates with the movement of the shelf to the latter position and discharges the small bundle of signatures on the shelf downward, and a signature stacking unit. It can be driven in the vertical direction and reversed in the horizontal direction so that the fold side of the small stack of signatures is placed in the opposite position one by one with the small stack of signatures. The turntable is equipped with a turntable that is driven upward to compress the stack of small bundles of signatures on the upper surface between it and the signature stacking shelf at the signature stacking position, and the press station is attached to a bracket that is moved up and down by a drive device. a first pressing plate for pressing an intermediate region of the stack of signatures; one end of the first pressing plate is rotatably connected to both left and right ends of the first pressing plate; pressing the left and right end areas of the stack of signatures; Components include a second pressing plate for rotating the second pressing plate, arms disposed on the left and right for rotating the second pressing plate, and an air cylinder plunger device for driving the arm, and the air cylinder - Plunger devices are arranged on the left and right above the first press plate and are installed on the bracket, the plungers of the air cylinder plunger devices are oriented laterally outward, and the left and right air cylinder plungers A signature bundling preprocessing device characterized in that an intermediate portion of the left and right arms is pivotally attached to the tip of a plunger of the device, and the tips of the arms are pivotally attached to the base end portions of the left and right pressing plates.

Function In the present invention, a small bundle of signatures is stacked on a shelf at the signature stacking position of the stacking station by an appropriate means, such as an appropriate mechanical force system or obtained. When the shelf moves out of the signature stacking range, the shelf is ejected from the station in cooperation with the stopper and placed on the turntable below. In this case, if a magazine that substantially surrounds the front, rear, left, and right sides of the small bundle of signatures is installed on the top surface of the turntable, the small bundle of signatures can be dropped onto the turntable without collapsing.

Then, the shelf is returned to its position and the turntable is raised. In this way, the small bundle of signatures on the turntable is compressed between the table and the shelf, the folds of the signatures are folded more tightly, the air trapped in the small bundle of signatures is forced out, and the bulk is reduced. It gets lower.

That is, in the present invention, the turntable, in cooperation with the shelf, contributes to pre-pressing the small signature bundle stack before the pressing process described later. It also serves as a preliminary press station for small bundles. Therefore, the turntable and signature bundle accumulation station can be advantageously implemented in terms of economy.

After the small bundles of signatures have been compressed, they are turned over so that the fold side of each small bundle of signatures is successively in the opposite position in preparation for stacking. This purpose is achieved by releasing the pressure on the stack of signatures by the turntable and the shelf and horizontally turning the turntable by 90° or 180° in the desired direction.

After completing the above processing, the small bundle of signatures is sent to a stacking station for stacking a certain number of bundles by suitable means, such as a suitable mechanical system known per se or by means of procurement, to a stacking press station for stacking signatures. Pressing is performed.

In the present invention, in the signature stack pressing station, by pushing down the bracket by its drive, the first or central pressing plate is lowered to first press the intermediate area of the signature stack, and then condition, then the left and right air cylinders
By driving the left and right arms by the plunger of the plunger device, the second, left and right pressing plates pivot to press the left and right end regions of the pile of signatures. Therefore, by pressing this intermediate region and then pressing the left and right end regions, air trapped in the signatures is effectively expelled, and the pile of signatures is also effectively pressed.

In this way, the present invention uses an air cylinder, which is a drive system separate from the drive device that drives the central press plate.
Since the structure is such that the left and right pressing plates are driven by a plunger device, when the central pressing plate presses the middle area of the pile of signatures, the left and right pressing plates can be pressed without further lowering the central pressing plate pressing bracket. The press plate can perform a press operation. For this reason, there is no need for a particularly large or high-output drive device to operate the central pressing plate, and the central pressing plate only needs to perform a press suitable for expelling air from the pile of signatures. output stuff,
In other words, it is sufficient to use a general size and output that can be obtained economically, and therefore it is possible to economically advantageously press the central pressing plate first and then press the left and right pressing plates. .

In other words, the present invention guarantees that very good results of pressing the stack of signatures can be achieved economically.

Effects of the Invention As described above, according to the present invention, the small signature stacking station including the turntable which is the signature reversing means, and the signature pile stacking press station can be economically advantageously realized. In view of the fact that very good results can be obtained from the press processing of the signature stack, it is purposeful to connect the signature pile stack press station to the signature small bundle accumulation station via the signature stack means as a pre-process. A tangible effect is brought about.
