Description

 The invention relates to the field of devices for finding a specific place in reference publications and protective equipment for them.

 A device for cutting holes in the stack of paper (A.S. N 825356, class B 42 F 21/12, 04/30/81) is known. This device provides cutting holes, but is able to process book blocks only in small quantities, as it was invented as a manual device for this operation, and therefore cannot be used in mass production.

A printing-punching device is also known (A.S. N 104899, class B 42 D 05/00 of 10/17/1955), in which there is a table for fixing blanks on it, a knife for carving an alphabetical path, a printing apparatus. The movement of the plate is communicated by a crank mechanism. The mechanism of knives is designed to clamp the leaf of the block on which the character is imprinted and the alphabetical path is cut out. Cutting the alphabetical path is carried out by two upper knives, set at 90 ^{o to} each other, performing reciprocating motion and interacting with the lower movable knives.

 Using this device, you can cut index ledges (alphabetical path), but its work includes manual operations associated with a significant investment of time, and, as a result, the inability to process a large number of book blocks. The design and principle of operation of this device cannot provide processing of several book blocks at the same time, which also indicates the impossibility of using this device in continuous production, in addition, the design and principle of operation of the cutting device (knives) does not provide for cutting smooth and even ledges.

 Also known is the production line for cutting holes in print media, adopted as the closest analogue, containing a conveying device, automatic page counters and a cutting device with a cutting element (application WO 93/24286, A1, class B 26 D 3/14, publ. 09.12 .93). Unlike the previous analogue, this device provides cutting holes, and not index ledges, which, due to their twisting during use, do not provide the necessary product quality. However, the production line according to the application WO 93/24286 has a low productivity due to the need for sequential processing of publications. In addition, the use of cutting elements of the cutting type makes this system very energy intensive.

 The objective of the invention is the creation of a production line for cutting holes, having small dimensions at high productivity, working both with book blocks in the process of their production, and with finished print media (in hard cover), producing high-quality products with low labor and energy costs.

 To achieve this technical result, in a production line for cutting holes in print media containing a conveying device, automatic page counters, a cutting device with a cutting element, the conveying device is designed as a rotating table mounted on a fixed support and divided into sectors with mounted on them loading trolleys equipped with automatic counters mounted on them, and the cutting device is rigidly connected to the fixed support and mounted above raschayuschimsya table, while its cutting member is a rotary cutter provided with a curved feeding mechanism, i.e. with curvilinear vertical feed describing the profile of the hole.

 Distinctive features of the proposed production line from the known one described above, closest to it (prototype), is that the conveying device is made in the form of a rotating table with a fixed pitch, divided into sectors, in which loading trolleys with automatic page counters are located. And the cutting device is located above the rotating table in the place of its fixation, and the cutting element of the cutting device works on the principle of a cutter, is located on its shaft and describes the path profile of the hole when feeding down.

 In FIG. 1 shows a front view of a production line; in FIG. 2 shows a top view of a production line; in FIG. 3 shows a general view of a cutting device.

 The production line (in Fig. 1,2) contains: a rack with a frame and guides for cutting devices (1), a cutting device for cutting holes installed on a guide rail located on the frame (2), a loading trolley with work tables (3) , automatic page counters located on the loading trolley (4), a rotary table with guides for loading trolleys and clamps for fixing them in the working position (5), the main rotary assembly with a working position lock (6), mounting support (7), clamp for a book block for a load trolley (8), an inlet conveyor for loading a trolley with blanks (9), an outlet conveyor for a trolley with finished products (10).

 The cutting device (Fig. 3) contains: a vertical feed mechanism (11), a curved feed mechanism (12), a chuck with a cutting element (13), a pressure table (14).

The production line is as follows:
Loading trolleys (3) with book blocks mounted on them in a horizontal position, clamped by clamps (8), are fed to the rotary table (5) from the conveyor (9) in the table step mode and are automatically locked there in the working position. When the trolley (3) is fixed in the working position, the cutting device (2) using the vertical feed mechanism (11) in this device automatically brings a cartridge with a cutting element (13) and a pressure table (14) to the edge of the book block, and after the pressure table (14) presses part of the pages of the block with a certain force, the mechanism of the curved feed (12) of the cartridge is turned on, and the cutting element operating according to the cutter principle cuts the hole along the profile defined by this curved feed, and the hole is cut in the direction from last pages to first. Next, the cartridge with the cutting element (13) and the clamping table (14) rises to its original position, and the table (5) rotates a step, while turning the table, a page is searched for the next index automatically with a page counter (4), table sector with loading the trolley approaches the next cutting device (2), set to the next index, and when the search for the desired page by the automatic page counter (4) ends, the operation is repeated, but for the next index. Next, the process is repeated until the hole is cut to the last index, and the cutting devices (2) are configured so that for a full revolution of the table, the number of holes on the book block is cut equal to the number of steps in the table (in our case, holes for 4 indexes are cut out of the table), therefore, in the general case, in order to cut out all the holes on a book block, you need to make the corresponding number of revolutions of the table (5) (on the book block, 20 holes are cut out for 5 revolutions of the table). As, after a certain number of revolutions, the trolley approaches the outlet conveyor (1) and the hole is cut to the last index, the hinged part of the frame (1) with the cutting device (2) located on it rises and the trolley with finished products is unloaded conveyor (10), and after turning the table (5) a step, the free sector of the table approaches the inlet conveyor (9) and a cart with new products is loaded on it, the cutting device (2) located above this sector of the table is automatically rebuilt odnoe position under the first index and the process repeats.

 It should be noted that the rotary table drive (5) of the cutting devices (2) and automatic meters (4) is provided by electric motors of the corresponding power.

 The whole process is set and monitored by a special program.

 Due to the fact that the device has small dimensions and one axis of the support, it is mounted and does not require special preparation of the room (level floor, foundation). In addition, the conveying device is made in the form of a rotating table, cutting holes for one index at a time on several book blocks located on the loading trolley in several rows, several rotating devices, so the line with very small dimensions is able to handle large runs of book publications.

 Also, due to the fact that the principle of a high-speed cutter is applied here, the design of the cutting tool of which provides a curved feed during cutting, it became possible to produce high-quality products. The power of the motors to drive this cutter is quite low, and the total energy consumption of the entire line is comparable to the consumption of household appliances. Due to the design of the device as a whole, it became possible to combine table movement operations (5) and page search by automatic counters (4). Also, a flexible module scheme, a multiple of 4, is used here, and, finally, due to the location of the book blocks at the workplace, the proposed line can work both with blanks and with finished editions in hard cover.
