Description

The invention relates to automated punching lines for sheet products and, in particular, can be used for punching crown caps for bottle closures.

The known line of stamping products from sheet blanks, contains, and the areas of pretreatment of the afterbirth: EIH, stopping the SHEETS and loading the presses, interconnected by a transporting cart.

Odiako In a well-known line there are several transport carts, which also entails an increase in the production area.

In order to reduce vehicles and production areas at the loading area of each of the presses, a forklift is installed, which ensures the removal of the SHEET feet from the trolley and the feeding press with sheet blanks.

FIG. 1 given total line; in fig. 2 shows the area of loading presses, VIEW side; in fig. 3 is a view along arrow A in FIG. 2; on fit. 4 - stop collector; in fig. 5 is a diagram of the removal of the front guide stopper when the cart is rolling out; in fig. 6-section on B - B in FIG. four.

A typical sheet production line usually includes a preprocessing area, which in this case is limited to an automatic feeder 1 standard SHEETS, DISK scissors 2 for trimming (calibrating) sheets and a conveyor 3. In many cases, this area

may include masking for lubrication, varnishing, inspection, sorting, etc. sheets.

The products are equipped with two presses 4. A single sheet feeding into the teress is carried out using vacuum tubes 5.

A trolley 6 designed for rails 7, laid between the loading zones of both presses 4, is intended for the sheets and sheets from the pre-treatment area, more precisely from the conveyor belt 3. In the loading area of the presses, fork lifts 8 are repaired, for example, pneumatic, forks 9 of which face the loading area of the trolley, i.e. the end of the tranporter 3. On the basis of the bearing surface 10 of the trolley 6, grooves 11 are made (FIG. 3 4) 9 lifts 8.

For stopping the sheets directly onto the trolley 6 at the end of the conveyor 3, a stop pan consisting of side

guides 12 (fig. 4) and face guides 13 (figs 2, 4, 5).

Some of the lateral guides 12 (fig. 4) are rigidly attached to the base of the conveyor 3, while others are rigidly attached to the uprights 14, which abut at one end

the floor, and the corners 15 are rigidly attached to their other ends. The other Ends of the corners 15 are pivotally attached to the conveyor 3.

The bars 15 (Fig. 4 and 5) serve to receive sheets of the conveyor 3, more precisely from its discharge rolls 16 (Fig. 4). From the corners 15, the sheet falls down onto the trolley 6 under the action of a sub-weight and, thus, a stack of sheets is collected on the cart.

The end guides 13 are installed in the lugs 17 (Figs. 2, 4, 5), and the lugs 17 are hingedly connected to the brackets 18 (Figs. 2, 5), which are fixedly mounted on the half-floor. At the lower end, the guides 13 have milled flats 19 (Fig. 6), which are inserted into the grooves 20 made in the upper part of the bracket 18 and can be rotated in them, i.e., to fix the guides in a vertical position.

The lugs 17 have stop surfaces 21 (FIGS. 2, 5) made of rubber for fixing the carriages 6 to the loading position. This fixation occurs when the guides 13 are raised to a vertical position.

During the operation of the line, the feeder 1 feeds standard sheets of gauge scissors 2, from which the sheets of the belt conveyor 3 enter the carriage 6, where they stop between the guides 12 and 13, falling onto the carriage from the corners 15 (Fig. 5).

When the cart is loaded with a stack of sheets of the required size, one of the side guides 12 (fig. 4 left) together with the uprights 14 and the corners 15 are folded up towards the conveyor 3, so as not to move the stack of sheets when the cart 6 leaves

and the end guides 13 rotate in the groove 20 of the bracket 18, they unlock and fold to a horizontal position along the rail 7 (Fig. 5), along which the carriage 6 pulls back and moves to the lift 8.

The forks 9 enter the grooves AND and appear under the foot. After turning on the lift, the forks raise the stack to the suction cups 5, which feed the sheets into the press. After the release of cart 6, she again

rolls over to conveyor 3, guides 12 are lowered, and guides 13 are raised, fixing the trolley. Produced next loading carts.
