Description

Known devices for supplying cardboard and similar sheets to cutting punch presses, made in the form of transporting sheets of paired receiving drums, connected by transmission with the same exhaust drums, periodically rotated from the cam to the press shaft by means of a ratchet gear.

The proposed device has the peculiarity that for the purpose of automatically shifting the sheets during the transition of the cabin from row to row, swing-guides and springs controlled from the press are used to periodically feed the sheet to the gripping discs of the transporting drums.

FIG. 1 shows a front view of the device in an exemplary form of its implementation; in fig. 2 is a side view of the device of FIG. 1 and in FIG. 3 is a top view of the fixture of FIG. one.

A sheet, cardboard transporting paired take-up drums / presses of the Albeco type are connected by a gear or chain drive with the same paired lead drums, not shown in the drawing, and controlled from the cam on the press shaft via an adjustable ratchet gear. The drums automatically feed the sheet to the amount required for cutting from it in rows of insoles and the like. Before the reels 1 is installed supporting sheet table (not shown). Before the whole sheet passes through the drums /, a new sheet 2 is superimposed on it, the front edge of which interacts with the stops 3, and the rear edge - with the strip 4, loaded with springs 5 towards the drums /. The shift of the springs of the new sheet along the table for refueling into the drums 1 occurs only after the trailing edge of the sheet in the process of cutting through the same drums passes and the stops 3 are lifted automatically. These stops are pivotally pointed to the ple20T

Cham 6 roller 7. To control the inclusion of the roller 7 in the kinematic connection with the lever 8, turning the axis 9 and driven back in rotation from the punch of the press, serves as a probe 10, supported between two edge disks of the lower drum I and freely attached to the roller 7. The bushing of the probe 10 is provided with a shoulder 11 connected by an earring 12 with a double-arm lever 13 swiveling on an axis 9. The second shoulder of the lever 13 is connected with a pawl 15, swiveling on the finger 18 of the lever 8 and installed by the leash 14 on the finger 16 of the lever 17 with turn the lever System //, 12, 13, 14 from lowering the probe 10. Installing the pawl 15 on the way of the finger 16 of the lever 17 causes longitudinal reciprocating movement of the lugs 3, sufficient to promote the new sheet by the force of the springs 5 and to load it into the drums /. The new sheet is advanced by the amount necessary for cutting the punch of the press of the first row of insoles, with the calculation of the location of their edges and the established distance from the sheet edge.
