(54) DEVICE FOR SEPARATION OF A FOOT OF NEWSPAPERS INTO SEPARATE PARTS

12

zet into separate parts, view: in FIG. 2 - conveyor's lodver, in an enlarged scale; on fit. 3 is shown at the moment of interaction of the stoics, located on the suspension, with a fixed stop.

The proposed device contains a periodically rotating drum / (fig. 1), the ao-generators of which are located the rollers 2, which are in contact with the stand 3, which is divided into parts.

The stand 3 is loaded onto the drum by means of a mechanism containing vertically closed, periodically moving chain conveyor 4 with paddle-shaped 5 in the form of combs, teeth 6 of which and (U-shaped logger 7 is installed. Guides 8 are installed along the conveyor 4, preventing rocking suspensions 5.

At the far end of the conveyor, the 4 ends of the drum / stationary stop 9 is installed, the B-shaped and nogib 7 teeth 6 are installed {fig. 2) interaction with him of the stack 3 (fig. 3), as a result of which this stop is transmitted to the drum /.

To facilitate the removal of the stop 3 from the teeth. The linear sections of these teeth are provided with rollers 10.

On the stop 9 is placed the sensor // levels of the remainder of the newspapers from the stack 3 on the drum /.

The device has a mechanism for separating the stacks to be separated from the total flow of identical piles, the folds of each of which are: by, returned to 180 ° relative to the previous one. This mechanism contains a sensor 12, which contacts with / passes through the roller table 13 piles 3 and sends a signal to the odioncore cyclic counter 14. The initial position of the counter 14 with the reset button / 5 is set on the allocated stack when it enters the rollers 16 of the roller table 13, which in the ashes of the interaction of this roller table with pendants 5 of the conveyor 4 are made. Console. A stop 17 is installed behind the sensor 12, placed on the way of the movement 3 of the electromagnet 18 liters about the signals from the counter 14 and the sensor //.

The drum / is driven by the motor 19 by transmission 20. The device operates as follows. Along the live rolls 13 and 21, identical stacks 3 move, the folds of each of which are 180 ° but relative to the previous one, to the device for their combination in packs (not shown in the drawings).

In order to form regular packs of newspapers in the movement path of these stacks, a device is installed for dividing them into separate parts and dispensing the separated parts onto a roller table 21, which is loaded in the following way.

The drum 1 can be loaded with piles, the folds of which are oriented to one side. These strings from the stream are extracted using the counter 14, whose initial position is set by the reset button 15

If the indicated stacks are located on the console rollers 16. After synchronization of the stacks moving in the tray and the states of the counter produced, you can always determine the orientation of the folds at the desk on console rollers 16 which are exposed to the signals at the counter output. the stop 17, in terms of switching the counter, is made from a sensor 12 in contact with the passing stacks.

When the number of newspapers in the stack on the drum / becomes less than the established norm, which is fixed by the sensor //m, the signal from this sensor goes to the COB drop circuit 22, which supplies the commander to turn on the electromagnet 18, which controls the movement of the stack. m 17. O. However, the electromagnet 18 is inserted after the matching circuit 22 in addition to the signal from the sensor // receives a signal from counter 14, fixing the presence on console rollers in front of the stop 17 of the stack, the folds of which newspapers are EFINITIONS manner, ie. e. stack drum suitable for loading /.

Simultaneously with the electromagnet / 5-the actuator (not shown) of the transanter 4 is turned on, the suspension 5 of which passes in the gaps between (Console rollers 16 and removes a stack of newspapers isolated from the stream to feed it to the drum 1.

After that, the electromagnet 18 is turned off, the support 17 is removed and does not interfere with the passage of the same table 3 on the roller table 2 / to the device for their combination in the packing. Conveyor 4 has several positions and is one step further each time, when the level of newspapers on the market does not / is below the established limit.

(When the suspension 5 moves with the drum / stack 3 allocated for loading, the latter is set back by the ear 9 and is taken off the drum / over the remaining newspapers (fi ;.

2.3).

Claims (4)

1. A device for dividing a stack of newspapers into separate parts according to ed. St. 441787, characterized in that, in order to ensure that it can be installed in an automatic production line to form bundles of newspapers, it is equipped with a mechanism for separating a stack of newspapers from the total flow to be separated and mechanisms for loading the first drum with a residue level sensor newspapers on the drum, while the conveyor in the overload zone is made console. 2. The device according to claim 1, wherein the mechanism for allocating the stack is provided with a sensor for the presence of stacks of newspapers connected to the BAT with a single-digit cyclic counter, the initial position of which is tired by the allocated stack upon receipt it on the roller rollers console rollers, and in: poro, m, installed behind the sensor. 3. The device is in PP. 1 and 2, characterized in that the drum loading mechanism with the selected stacks is equipped with a vertically closed conveyor with iB suspensions, in the form of combs and a fixed stop.
