Abstract

Installation for cutting holes in prints, containing a conveying device, a cutting device with a cutting element, characterized in that the conveying device is made in the form of a rotating table with a fixed pitch mounted on a fixed support and divided into sectors with installed work tables, and cutting the device is rigidly connected to a fixed support and mounted above a rotating table, while its cutting element is made in the form of a rotating cutter equipped with a cry mechanism olineynoy supply.

Description

Installation for cutting lznok in print media

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

A device is known for cutting holes in a stack of paper (AS No. 825356, class B 42 F 21/12 of 04/30/81). This device provides holes for holes, but it can only process book blocks in very small quantities, as it was invented as a manual device for this operation, and therefore cannot be used in mass production.

It is also known printing-punching device (AS No. 104899 class. In 42 D 05/00 from 10.17.55), 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 silence 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 pressed. Cutting the alphabetical path is carried out by two upper knives installed at an angle of 90 degrees to each other, performing reciprocating motion and interacting with the lower movable knives.

Using this device, you can cut index ledges (alphabetical paths), but its work includes manual operations associated with significant time costs. The design and principle of this device cannot provide processing of several book blocks at the same time, except for TQro the design and principle of operation of the cutting device (knives) does not provide cutting of smooth and smooth ledges.

Also known is adopted, as a prototype, a device for cutting holes in prints, containing a conveying device, a cutting device with a cutting element (application No. 093/24286 AI C. B 26 D 3/14, publ. 09.12.93,) which provides cutting holes, and not index ledges, which, due to their twisting during use, do not provide the necessary product quality. However, the installation has low productivity due to the need for sequential processing of publications. In addition, the use of cutting elements of the cutting type is not able to provide sufficient purity of cuttings, and also makes the entire system energy-intensive, and the installation also has rather large dimensions.

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

To achieve this technical result, in the installation for cutting holes in print media containing a conveying device, a cutting device with a cutting element, the conveying device is made in the form of a rotating table mounted on a fixed support and divided into sectors with working tables installed in them, and a conveying device rigidly connected to a fixed support and mounted above a rotating table, while the cutting element is made in the form of a rotating mill, equipped with a mechanism curved feed, that is, with a linear stroke describing the profile of the moons

The property is made in the form of a rotating table with a fixed pitch, divided into sectors in which the working tables are located. And the cutting device is located above the rotating table at the place of fixation of the working table, and the cutting element of the cutting device works on the principle of a cutter, is located on its shaft and describes the trajectory of the hole during the downward stroke. The proposed installation is illustrated by drawings:

FIG. 1 shows a front view of the installation;

FIG. 2 shows a top view of the installation:

The installation of FIG. 1 and FIG. 2 comprises: a cutting device (1), a cutting element (2), a rotary table assembly (3), a mounting support (4), work tables with locks for working positions of book blocks (5), a rotary table with table position fixers (6).

The operation of the installation is as follows:

Book blocks are installed on working tables (5) in a step-by-step mode and fixed in the working position, the operator’s place being in the free sector of the table (6) to the sector with the cutting device (1), but as the cutting device (1) with the cutting element (2) automatically selects indexes, alternately on all sectors of the table (6), after passing the first circle, when all book blocks are sampled for the first index, the operator presses the button to shift the cutting device by a step equal to the distance Between adjacent holes, which is predefined on the cutting device, and the process is repeated anew for the next index, it should be noted that the page search process is performed by the operator during the main working time of the cutting device (during the hole production time), the working cycle of which is started by the operator after each fixation the table by pressing a button on the operator's console. As book blocks are processed, they are also unloaded step by step, and new book blocks are put in their place and the process repeats.

Thus, a sufficiently high processing speed of book blocks is achieved, and on the part of the operator there is constant visual control over the page number.

In general, the installation, with all its simplicity, cost-effectiveness and compactness, allows you to process large enough print runs, it can also be inscribed in the main book production process, or it can also process finished prints (in hard cover).
