Description

The present invention relates to a machine for stuffing slats on the sheaves of batches in which a known device is used for making wire from wire, K-shaped brackets and clogging them in connected parts of the cloth and the bar fed by an endless conveyor. According to the invention, the slats are fed from the magazine to the nests of the conveyor and are fed to the fixture for the backwater during the period of driving the brackets into it, corresponding to the instant of automatic shutdown of the conveyor; this stop is made by the impact of a knuckle disk on the pulley, disengaging the clutch discs placed on the screw shaft, telling the movement to the conveyor; The cam disk is driven, in turn, by a flywheel that sits freely on the same shaft with a jammed cam disk and transmits movement through the clutch of a cam on a disk with a roller on the flywheel pin.

In the drawing of FIG. 1, a diagram of the general form of the machine for stuffing the slats on the sheaves of rungs; FIG. 2 is a scheme for transmitting movement from the flywheel to the conveyor; FIG. 3 is a schematic of a device for coupling and disengaging a coupling on a screw shaft communicating movement to a conveyor; Fig, 4-scheme of the mechanism

for switching on the cam shaft and control system of the levers for feeding the wires from the coil and for activating or stopping the conveyor; FIG. 5 and 6 is a diagram of the general view and vertical section of the device. for making V-shaped brackets and inserting them into the joining parts.

The proposed machine is driven from a driving belt by means of a pulley 33 (FIG. 2) attached to a fly wheel 32, freely rotated, on a shaft QZ- With the help of two pairs of conical gears 34-35 and 36-37, the worm rotates in rotation 38, connected to the worm gear 38 (Fig. 1), mounted on the drive shaft Q of the conveyor (Figs. 1 and 2); The conveyor chain rests on two valuable teeth mounted on the shafts Oi; To tension the conveyor chain, the tension roller 61 serves. A web attached to the bar coming from the magazine 6 and clamped in the cells of the conveyor chain thus receives movement along with the latter.

The web from the roll fits through the roller b and a number of supporting wooden plates 13 to the knives that make the edges of the feed conveyor web. Next, the last with curved edges, bend rollers T

and 8, fits into the stapler 15, gradually being laid on strips fed from the magazine 16 into the slots of the conveyor. Between rollers 7 and 8, three brackets 7 are placed, smoothing the edges of the web and serving simultaneously for the sake of being.

When the conveyor, and hence the web, moves, the shaft of Oz is at rest; At the same moment, when the conveyor brings the bar under the device 15. The K-brackets with the K-brackets, the pins 42, which are on the conveyor chain (Fig. 4), periodically act on the lower end of the pivoting lever 41, as a result of which the upper end of the lever 41 disengages with the fist 49. The freed fist 49 under the action of the spring 51 rotates about its axis O so that its protrusion 4 moves away from the center: shaft Oa, on which the cam 25 is jammed, connected with the finger to the fist 49- Protrusion 4 of the latter when the center of Oz is removed enters intermittently There is a clutch with the roller 50 fixed on the trunnion of the flywheel 32, which is free to sit on the axis Oz and receive a constant rotation.

This produces a clutch of Oz's cam shaft with a continuously rotating flywheel 32. A periodic clutch 49 coupling with a roller aims to drive a cam plate 25 controlling the movement of the lever 23 connected with the belts 22 and 40. The clutch of the roller 50 on the axle pin: Vika 32 with a protrusion of the fist 49 does not occur immediately after the last is disengaged from the upper end of the lever 41; roller 50 may not reach protrusion 4 of cam 49 by 350 °. As long as there is no engagement of the flywheel 32 with shaft 02, the latter does not rotate: and the web does not stop moving. The transponder pin 42 is disengaged from the lower end of the lever 41, the latter is driven to the initial position by the action of the spring 41, and the rotation of the disk 25 with the shaft Oz is not excluded, since the fist 49 is retracted by the spring 51 to the operating position. Thus, the shaft can only make one revolution, at the end of which the fist 49 is removed from the working position above the end of the lever 41, and

the clutch of the roller 50 with the protrusion 4 of the cam 49 is broken.

At the beginning of the rotation of the shaft Og, the roller 24 rises upwards, as a result of which the lever 23 rotates, lowering the connecting rods 40 and 22 (Fig. 4). A ha 40 acts on the coupling coupling 17 placed on the shaft of the screw 38, which informs the movement of the conveyor, separates it and the screw to 38 stops.

The latter is turned off by the time when the bar in the conveyor nest is in the position required for driving the brackets, and is done when the pull 40 is lowered (Fig. 3), so that the latter acts on the lever 39, lowering it down. The lever 39 controls the spring stop 42, which periodically engages the spring cam 44, rotates it about the axis Or, one of the disks of the coupling coupling 17 (Fig. 2), as a result of which the cam 44 separates from the finger 46 on the other disk 46 of the same the clutches 17. By the end of the shaft shaft Oa turn, the lever 40 rises, the stop 42 under the action of the spring 60 rises with the right end upwards and the cam 44 is put by the spring 45 into the working position (Fig. 2 and 3).

A ha of 22, serving to actuate the mechanism for feeding the wire 18, while lowering, also lowers the dog 20, which slides over the ratchet 21. By the end of the shaft rotation Oz, the ha 22 rises with the lever 23, pulling up and the dog 20. Last, clinging to the ratchet 21, rotates the rollers 19 between which the wire 18 is clamped (Fig. 1) and feeds it into the device 15 for the manufacture of brackets (Fig. 1). The wire 1 goes down, passes through guides 57, feed rollers 19, second guides 57 and enters device 15 for making F-shaped staples and inserting them into connected parts.

Two cam discs 1 and 2 are wedged on the shaft Oz, of which the first 1, 1 lower part 28 through rollers and rods, while the second 2, 2 lower part 29 through rollers and rods 27. Upward movement of parts 28 and 29 is carried out springs 48 by means of levers 47, wherein the up and down movements of parts 28 and 29 are supported by the same cam disks 1 and 2.

From parts 28 and 29 there are a series of 30 and 31 to the bracket device 15, which perform the necessary operations with the wire.

T ha 31 acts on the drummer 54 (Fig. 5 and 6), which, when moving down, cuts off the wire 18, which is sharp at the left end of the strap 3, and which is advanced at the end of the previous working turn through the matrix 56 and. somewhat lowers the cut piece of wire 18 down to the anvil 53. Simultaneously with the drummer 54, the plate 55 is lowered and pressed, which receives movement from the part 28 through the pull of 30. When the wire 18 is lowered onto the anvil 53, the plate 55 stops, and the drummer 54 continues to descend , bending the wire through the anvil 53 into the K-shaped brace 52. When the latter is made, the anvil 63 extends the wedge 53 outward, freeing the way for the brace -52 to move downwards, in order to insert the latter into the connected parts. After the anvil 53 is removed, the pressure plate 55 continues downward, displacing the bracket 52 beyond the limits of the device 15 attached to the square 14 (Fig. 1). The drummer 54 reaches its lowest position before the bracket 52 begins to exit the device 15. The upward movement of the drummer 54 and the pressing plate 55 occurs simultaneously.

From the bottom of the upper branch of the conveyor, a device is placed for backing the lanka during the period of driving brackets into it, consisting of a block 9, which levers up when the conveyor is stopped, pressing the bar to the canvas and to the bracket device 15. This lift is achieved by means of the lever 47, which when its movement from the fist disk on the axis 0 lowers down tgu 12, turning the crank arm 11. The latter is connected by the pull 11 to the wedge 10, which, in turn, while moving, resting on the roller 61, lifts the pad 9.

The subject matter of the invention.
