Description

one .

The invention relates to the maintenance of flat items and can be used in postal communication for a set of newspapers of different types for one subscriber, in printing for brochures from individual sheets, as well as in paperwork for a set of sets of documents.

A device for a set of printed products is known, which includes accumulators, separators, belt or pushing conveyors and a receiver of the assembled set tl.

However, this device is inefficient and unreliable, and also kinematic difficult, has large dimensions and weight.

It is also known a device comprising a cassette for printed products, an endless belt with a group of holes, a vacuum chamber located under it and a cutter, which has an increased reliability of operation 2.,

However, such a device is applicable for separating flat objects of a single foot, further sorting individual objects from one foot, and further sorting individual npej mets according to various criteria. In the case of its use in devices for recruitment (sets of various feet of flat objects, this device will have decree deficiencies, due to the need to use additional transporting and component mechanisms.

The purpose of the invention is to increase productivity by simultaneously transporting and assembling the kit. printed products, the vacuum chamber is made sectional with a separate supply of vacuum to each section and has longitudinal grooves, the length of each of which is equal to About this, from the corresponding cassette to the cutter, the groups of holes are infinite in its transverse direction; they are placed opposite the slots of the vacuum chamber 1, and in the longitudinal direction they are located at a distance smaller than the width of the printed product sheet. FIG. 1 shows the device, top view; in fig. 2 is a side view of a vacuum chamber and an endless belt (section A-A in FIG. 1); in fig. 3 - vacuum chamber, (section BB in Fig. 1) on. 4 - device, view in vzometriya The device includes a number of accumulators 1, a vacuum chamber 2, an endless band 3 With a group of holes 4 and a shut-off device 5. The vacuum chamber is made sectional with a separate supply of vacuum to each section, each section containing slots 6 from, the corresponding storage ring to the clipper, and the openings 4 of the infinite chucks 3 are shifted in the longitudinal one. relative to each other at a distance less than the width of flat items to be assembled 7. The accumulators 1 are configured to feed flat objects by removing them, for example, using force sensors, and are equipped with rollers 8 rotating in the opposite direction of movement of objects 7 for eliminating the possibility of separation of two flat items.,. The device works as follows. The vacuum is supplied to the necessary sections of the vacuum chamber 2. After separating the flat object from the first accumulator, if the hole 4 coincides with the corresponding groove 6, it moves to the next accumulator by holding onto the endless belt 3. When a separated object enters the next accumulator zone, a detaching flat object is separated by matching the corresponding hole 4 and groove 6. Next, the first and second parts — ie, objects held on the tape 3 by vacuum and displaced relative to each other by an amount less than their width , mix to the appropriate drive, and so on. After the last accumulator, the vacuum is stopped (the end of the grooves 6 of all sections of the chamber 2) and with the help of the shut-off device 5 the objects are combined to form the required set. According to the measure from the boron of objects from the accumulators, the packs of objects are fed to the infinite pouring by means of a special mechanism with a force sensor (shown in the fig.). Rotation of the rollers 8 in the opposite iCTOpoHy of the movement of objects eliminates the possibility of separating objects, objects. Thus, the application of the proposed device allows to increase its performance in comparison with the known one due to the simultaneous transportation and ccmv of the recruitment of the kit. Moreover, with the software set of printing sets, the control system of this device is greatly simplified. Apparatus of the Invention A device for a set of printed products, mainly lyots and newspapers, containing a cassette for printed products, an endless tape with a large hole, a vacuum chamber underneath it, and a cut-off device, characterized in that, in order to increase productivity by simultaneously Of the transport and assembly of the kit, it has additional cassettes for printed products, the vacuum chamber is made sectional with a separate supply of vacuum to each section and has longitudinal grooves, the length azhdogo of which is equal to the distance. This means that from the corresponding cassette to the secatel, the groups of holes of the endless tape in the transverse direction are placed opposite the vacuum chamber, and in the longitudinal direction they are located at a distance smaller than the width of the printed product to be printed.
