The invention relates to the woodworking industry, in particular to equipment for the manufacture of containers.

The purpose of the invention is to increase productivity and expand technological capabilities.

FIG. 1 shows a press with fixed punches, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - device for filing nails for punches, general view; in fig. 4 - the same, top view; in fig. 5 and 6 are the interrelationships of all the elements of the device in dynamics, at the time of simultaneous filing of several nails from the vibrating hopper to the pressing blocks, arranged in a checkerboard pattern.

The press (Fig. 1) consists of a bed 1, guide columns 2, sleeves 3 with a board 4 fixed on them, a carriage with rollers 5 for rolling nails.

Wooden workpieces 6 are placed on the rollers. The gearbox and electric motor 7 are connected to cams 8 and 9 and wedge 10. Punches 11 are fixed, rigidly fixed on crossbars 12, enter into the body of block 13 of pressing in nails with clamps 14 by tray 15.

A device mounted on the press for the simultaneous selection and filing of nails (FIG. I) is provided with an annular ferrule 16 (FIG. 3). In its bottom part, the axis 17 is rigidly fixed vertically on which the bevel gear 18 is attached, paired with the horizontal bevel gear 19, having at the end of the connecting roller passing through the axis 17 a coupling 20 (for connecting with the engine), a rotary disk 21 with internal 22 and external 23 cams, having grooves 24 for the passage of nails 25. The number of grooves 24 coincides with the number of simultaneously supplied nails into the pressing blocks for punches 11. The taper shchesthern 18 and the rotary disk 21 are fixed on the axis 17 by a nut 26. Inside the gear wheel 18 in special bore IO displacements plunger-stopper 27 with the spring 28 bearing against a stationary cam 29 on fixed on the axis 17.

In the lower part of the disk 21 made the lugs 30, and under the grooves 24 and the grooves 31 in the case of the holder 16 fixed trays 32.

The bolts 33 fasten to the annular cage 16 of the housing clamps 34, where the guide sleeve 35 is mounted for nails 25 with grooves, which include the ends of the clamps 36, which are kept from moving by flat springs 37 fixed in the housing by screws 38, as well as levers clamps 39 on the axles 40, pressed against the movable cams 22 and 23 by pins 41 by means of springs 42 supported on nuts 43. The cam 44 of the movement of the entire system is mounted on a bevel gear 18. The rod 45 of the vibrating hopper 46 is housed in the housing 17.

The device works as follows. Interrelation of all elements of the device with simultaneous filing of several nails from the vibrating hopper 46 through the tray 32,

The tray 15 of the body of the pressing-in unit of the nail 13 is shown in FIG. 5 and 6.

Through special grooves in the hopper 46, the nails 25 fall into the guide sleeve 35, where they are placed one above the other. Electric motor switched on

(not shown), and through the coupling 20, the movement is transmitted to the horizontal bevel gear 19 and then to the bristle 18 rotating around the fixed axis 17. The plunger-stopper 27 slides along the fixed

5, the cam 29 of the axle 17, compressing the spring 28, rises up and comes into contact with the anvil 30 of the disc 21. From this moment on, the actual operation of the device begins.

0 FIG. 3 and 5, an option is given when eight housings-locking clamps 34 are mounted on the annular cage 16 (one of eight is shown), i.e. eight nails are simultaneously fed in 45 ° turn

5 movable cams 22 and 23. The rotation of the disk 21 begins. Let us go 5iB2. The stop 30, the cams 22 and 23, the disk 21 are kinematically rigidly connected to each other (Fig. 5, line B), therefore, when according to Fig. The 6 points A, the movable cams 22 and 23 will approach the locking levers 39, the lifting will begin, they rotate around the axes 40, and simultaneously at the AI points of the maximum lifting of the cams 22 and 23 the fixture 36 is moved, compressing the flat spring 37, and clamping the nail standing over

5 nail 25, not allowing it to move down. The movement of the cams 22 and 23 continues, after the passage of the AiAs line, nails are fixed. Bottom nail with its tip on the disk surface

d 1, and the nail above it is compressed with clips Groove 24 goes, after the passage of the BiB2 path, the free bottom nail falls into th & 24, then into groove 31, tray 32 and further into tray 15. At cams 22 and 23 fall, locking levers 39 are spent, releasing nails 5, which fall down along the guide bushing 35, loading for the next feed, onto disk 21. At this point, the recession and on the fixed cam 29. The plunger-stopper 27 is returned by the spring 28 to its original position. But the rotation of the brush 0 or 18 continues until the cam 44 turns off the electric motor (not shown), the cycle for nailing under the fixed punches is completed. In the future, the cycle of issuing nails is repeated.
