Description

There are known devices for perforation of years, cards, items of stamping, etc., containing a mechanism for feeding the carrier material, a matrix, and nunsons that can be controlled by electromagnets.

The proposed ycTpoiicTBo from.hmchatsl from known than. that in order to increase the speed of perforations and reduce the dpnamic loads, the punch holder and Maipima are made in the form of cylindrical drums, one of which has matrix holes, and another 1-adjustable iansons .- To synchronize control of nuance. mn with the rotation speed of the cylinders of the matrix ij It contains clock scales located on a drum with nuansons, a photoelectric reading device and an accumulator with a daily accumulator. In order to synchronize the moment of switching on the mechanism for supplying the material to the carrier 1, there is a photoelectronic device connected electrically to the stop mechanism for activating the carrier mechanism at the time of the clock pulse.

FIG. 1 is provided) on the onstable device; neither FIG. 2 - an anonymous drum with an installation and damping device (side view), as well as part of a matrix drum; in fig. 3) but less than separate units and parts of the device, directly in the process of non-perforation; on fng. 4-weathered weft cumulative block.

An onsiped device consists of a dongle. matrix drum 2, the mechanism 3 feeding the carrier material, mouth

NEW DEVICE 4, locking and extinguishing device i n prome, exactly. 0 storage 6, mounted on the frame 7.

The punch drum / consists of two cylinders 8 inserted one into the other and I have carrying punches 10. For ease of mounting punches / Outer cylinder 9 is divided into several segments. Between cylinders 8 and 9, locking and extinguishing movable strips 11 and 12 for punches 10 are installed. Several sets (fields) of punches 10 are located around the entire drum circumference. This reduces the time between perforation of individual cards 43, as well as the idle time to minimum. In accordance with the vertical rows of the cards 13 to be punched, magnets 14 are rigidly fixed inside the punch drum, each of which is connected to the corresponding hammer / 7 by levers 15 and 16. The latter is transferred to the working position (presses the corresponding punch) by the adjusting device 4, which, in turn, is controlled by means of the gear 18 in such a way that with each horizontal row of one set it performs one working stroke.

On one of the face sides of the punch drum, the clock facets 19 and 20 are located, which, using photocells 21, generate two different pulse sequences. A clock scale 19 shortly before the punching process begins for each set produces a pulse that synchronizes the flow of cards through the stopper 22 at the peripheral speed of the drums / and 2. The touch bar 20 produces a pulse for each row of punches so that the magnets 14 will transfer the hammers 17 at exactly the exact time. in working position. The feeding and withdrawal of the cards are carried out by friction rollers 23. The rotation of the matrix drum is precisely synchronized with the rotation of the punch drum.

Intermediate drive 6 is designed to ensure continuity of the perforation process and stores the output data of the computer. The drive is made on the relay, but can be built on other elements, such as ferrites. The described device operates as follows. The cards 13 to be punched are transported by the feed mechanism 3 to the stopper 22, where they are held until the clock pulse of the clock scale 19 closes the second contact of the circuit 24. The first contact of this circuit is closed by the photocell current 25, which is activated when there is a card at the stopper 22. When the closure of the second contact of the circuit triggers the magnet of the stopper, and the punch card enters the gap between the drums. The first clock pulse pzhaly 20 includes a relay 26 of the circuit 27, through which information from is transmitted to the corresponding magnets 14. excited elements accumulator. The magnets transfer the hammers / 7 to the working position, at the same time the installation bridge extends the corresponding punches by means of these hammers. The second clock pulse of the scale 20 switches on the relay 28, as a result of which the current circuit of the first row of the accumulator with magnets is interrupted, and the current circuit for the excited elements of the second | 1 and the accumulator with the corresponding magnets 14 is closed, and then the second punches of the set are installed similarly described. Similarly, the installation of punches in the following sets of sets and in subsequent sets. During the time of the installation process described in the card 13, the corresponding rows of a pre-installed set of punches are perforated.

Since the installation process of the subsequent set rows ends before the end of the perforation time of the previous rows of the previously placed set, the idle time in the described device is completely absent. After the end of the certification process, an extinguishing magnet is activated; shifting the locking or damping bar, with the result that the punches under the action of the springs 29 are reset.

The described device increases the rate of perforation of the carrier material and reduces the dynamic loads.
