Description

The subject of the invention is an automatic rolling machine for marks on cylindrical articles, which, however, are fed to one of the bunker on the support rollers and processed by a stamp placed on a slider that performs a reciprocating motion. However, such machines are usually not compact enough and complex 1 during assembly.

In the described automatic machine, these disadvantages are eliminated by the fact that the body of the rolling mechanism, which includes the slide, its supports and support rollers for processing) 3. products made prefabricated of two plates, shtable by screws. For the direction of the slider during its reciprocating motion in the machine, rollers are used, which interact with their conical surfaces with slant bevels. In addition, the support rollers for machining (the wired products are provided with steps that are intended to restrict the movement of products in the axial direction when being fed by levers controlled by slider bevels.

FIG. 1 shows the kinematic scheme of the described machine; in fig. 2 - machine in vertical section; in fig. 3 is a section along A-A in FIG. 2

Arranged machine as follows.

The motor / (Fig. 1), the belt drive 2 and the gearbox 5 are designed to drive the camshaft 4, which makes one revolution per cycle, during which one product is processed. From the cam 5, through the lever 6 and the hinge rod 7, it is driven into a reciprocating slider 8 carrying glue 9. The slide of the slider is reversed by means of a load 10 connected to the slider 8 by a cable (or chain) 11 thrown through the rollers 12 rotating on the axles 13. The cam 14 through the lever 15 and the pusher 16 of the workpiece 17 is removed after processing from the working position.

No. 133785

The slider 8 moves along two rollers 18, 1 located above it, the masses of conical guiding surfaces, corresponding to the bevels in the upper part of the slider. To the upper rollers, the scroller is pressed by the lower spring-loaded rollers 19. to rotate the bifurcated dog 22, which regulates the supply of blanks through the loading tray 23, leading from the loading cassette 24. The dog is rotated in the opposite direction by means of the spring 25. The rail 21 when the slider moves through the pusher 26 27 flushes haymaker, intended to break the arch in the loading cassette 24.

In the windows of the slider 8 installed boot 28 (Fig. 2) and reception iibiii 29 trays. When rolling, the workpiece is wound on the rollers 30 supported through the axles 31, the pad 32, the bracket 33 and the molded rack 34 on the package of prestressed poppet springs. The pusher U5, mounted inside the rack 54, carries an insert 35 extending between the rollers 30. Near the stamp 9, the slider has bevels 36 (Fig. 1), by means of which the spring-loaded lever 37 is rotated, pressing its workpiece with the base end a (Fig. 3) to ledges b rollers. The rollers 12 and 18 (Fig. 2) are mounted in plates 5 with spacers 39, In the receiving tray 40 leading to the receiving cassette 41. There is a spring-loaded pawl 42, which prevents the return movement of the leached blanks. The bracket 43, which has a groove for feeding 3ArOiBOK to the rollers 30, prevents an arbitrary falling out of blanks 28 and 29. The plates 38 and the trays have windows and slots for observing the blanks in the working position and as they move along the trays. The machine is equipped with an electropulse counter of machined parts with a sensor 46 and light forms, which are included in the usual circuits.

At the beginning of the cycle, which corresponds to the extreme left position of the slider 8 (Fig. 2), the workpiece from under the pawl 22 falls into the loading tray 28 of the slider. Overlying blanks are held by the upper tooth of the pawl 22. When the slider moves, the lower blank from the loading chute 28 of the slider falls onto the rollers 30. When the skid 36 moves to the lever 37, the lever turns and sends the blank all the way to the ledges of the six rollers 30.

Next, the impression is rolled by stamp 9, then snarling - 37 is retracted from the workpiece by another bevel 36. approaching the rightmost position, cam 20 rotates pawl 22, B resulting in the upper protrusion of the pawl and the lower protruding. The tick-blank in tray 25 is lowered onto the lower lip (tooth) of the dog. In the extreme right position of the slider, the receiving tray 29 of the slider is installed above the machined workpiece between it and the receiving tray 40. The processed workpiece insert 55 of the pusher 16 but fits into the receiving tray 29, while the entire column of workpieces in the receiving tray rises and the top the harvesting of this post rises above the dog 42 and is cut off by it. The wall of the receiving tray 29 has a small gentle bevel, through which the workpiece is moved when the tray is in the axial direction. The pusher 16 lowers and stops in the intermediate FIO application so that the bottom blank from the slider's receiving tray does not get stuck when the slide moves backward between it and the bracket 43 and at the same time that the stamp 9 does not catch on the insert 5.5.

The length of the receiving channel of the slide must be a multiple of the diameter of the workpiece.

During the reverse movement of the slide, the cam 20 releases the pawl 22 (after passing the receiving tray 29 under the loading tray 23). The dog from the workpiece is turned in the opposite direction. Blanks in tray 23 occupy their original position. At the end of the return stroke, the plunger 16 lowers and returns to its original position. Then the cycle repeats.
