The lindra 12 and the guides 15 are connected to the bed 1 by means of studs 16. The pneumatic actuators 12 are powered in a known manner with the shop line of compressed air and are equipped with well-known control valves (not shown). A trolley 18 is located on the rails 17, moving between the repacking station and OK-I machines. On the uprights, the trolleys are from a support 19, which correspond to the legs 20 of a candlestick package 21 consisting of the bottom 22 (collector) and the top 3 plates, and st. with nuts 25 connecting the lower and upper plates, freely covering the straps 24 columns 26, mounted on the upper plate 23 with the possibility of vertical movement relative to the tie bars and the upper plate and limited from turning by the sliding key 27. The columns are designed as T- form th projection 28, and the cylindrical portion columns are made sloping shoulders 29 formed lys- kami tymi removed from opposite sides of the diameter. On the top plate, wedge valves 30 are mounted that can be rotated around an axis 31. A massive handle-weight 32 is loosely seated on the same axis. The wedge valve 30 is equipped with a finger 33 and a wedge 34 made in two parallel sections of the helix 35 between which have a through groove 36 in which the lower part of the column 26 is located with the flats. At one end, the groove 36 has an extension 37, corresponding to the diameter of the cylindrical part of the column. 26. The T-shaped protrusions 28 of the columns 26 are located in the grippers 5. Between the lower and upper plates of the bag are placed a candle set 38 with cake cakes 39 collected in stacks on perforated candles 40 fixed on a tray 4 1. Between the bottom plate and the pallet there is a rubber seal 42, reinforced in the bottom plate.

Repacking point works as follows.

The OK-I machine installs the finished package 21 on the trolley 18, on the vertical posts of which there are supports 19 corresponding to the legs of the candle package 20. On rails 17, the trolley is moved from the OK-I car to the repacking station, with this

The second arm of the rocker arm 7 is lowered by the hydraulic actuator 9 in such a position that the T-shaped protrusions 28 of the columns 26 enter the expanded part of the grippers 5. After that, by the hydraulic actuator 9, the right shoulder of the rocker arms 7 rises, the grippers 5 engage the T-shaped protrusions of the 28 columns 26 and the entire bag is lifted up to the stop of the upper plate 23 into the bed 1 of the repacking point.

At the upper position of the bag (Figs. 1, 3, 5, 6, 9 and 10), the finger 33 of the wedge valve 30 is located on the path of movement of the slider-pusher 14, which in the initial position (Fig. 3, 4 and 12) is extended by the pneumatic cylinder 12 to the left extreme position. In this position, air is supplied to the left cavity of the pneumatic cylinder 12, and the piston will move the slider 14 to the right. The latter then engages with the finger 33 (FIG. 6) of the wedge valve 30 and turns it to the right around the axis 31 until the expansion 37 of the groove 36 stops in the column 26. With this turn of the valve 30, its wedge part 34 will come out from under the inclined shoulders 29 columns 26 and thereby disassociate it from the upper plate 23. After switching the crane 10, the oil from the pump station is fed into the upper cavity of the upper cylinder of the hydraulic actuator 9, while the right arm of the rocker arm 7 is lowered, supporting frame 6 with the roller 6, also lowering this from horizontal the frame 4 is secured by the rollers 3 sliding in the vertical guides 2. The grips 5 fixed to the frame 4 are also lowered, while under their own weight the whole package 21 held by the grippers 5 by the T-shaped protrusions 28 of the columns 26 also drops to the contact between the paws 20 of the upper plate 23 and the supports 19 (Lig. 7) of the uprights of the trolley 18, after which the movement of the upper plate 23 of the bottom stops.

When the package 21 goes down, the finger 33 on the valve 30 will be disengaged from the slider 14 (Fig. 7), and the latter will move the pneumatic cylinder 12 to the right to its extreme position (Fig. 8). When lowering the rocker arm 7, the frame 4 and the grippers 5 upper plate 23 remains stationary, lowering the columns 26 and resting on these columns with nuts 25 of the stitch 24 with a bottom plate 22 hanging on the peak and a candlestick set 38 placed on it, thus creating a gap between the bottom of the upper plate 23 and the top of the cake 39, which allows candlestick set 38 of package 21. This operation is performed with a special automatic reloader (Application constituting a) or according to the scheme of operation, existing at present in the chemical fiber industry, auxiliary hand truck with forks. When changing the candlestick set, the lower cylinder of the hydraulic actuator 9 is also used, but this part of the movement of the rocker arm 7 and the elements associated with it does not directly affect and is not driven. Instead of the finished candlestick set 38, a set with unfinished cakes is placed, which in a free state are raised above the top edge of the candles 40, after which

of the slider 14 (FIGS. 9 and 10), and the inclined shoulders 29 of the columns 26 are located above the screw surface 35 of the valves 30, which are in the right extreme position. Air supply in the right cavity of the pneumatic cylinder 12 moves the slider 14 to the left. In this case, the slide blocks 14 will engage with the fingers 33 (Fig. 10) and with further movement to the left, the valve 30 rotates around the axis 31 until the screw surfaces 35 with oblique shoulder 29 of the columns 26 are jammed, thereby fixing the bag in the pressed state. In this case, the rotation angle of all four valves will be different due to the fact that the inclined collars 29 of columns 26 are located at different heights from the screw surfaces 35 of the valves 30. This is due to the fact that the straps 24 and other elements of the package, the design of the repacking point and the rubber seal

Crane 10 switches the flow of oil into the lower cavity of the upper cylinder of hydraulic actuator 9, while the right shoulder of the rocker arm 7 rises, dragging up the frame 4 and the claws 5, which re-engage with the T-shaped protrusions 28 of the columns 26 and further up the movement up through the station 24 is transmitted to the bottom plate 22 and the candle set 38 arranged thereon.

The slight angle of the screw surfaces (-8) determines a rather perceptible difference in the rotation angles of the wedge valves 30 in each of the four columns 26. With the difference in the height position of the inclined shoulders 29 of the columns 26, the position of the finger 33 along the stroke of the slide 14 for each of the four valves 30 different, i.e. The stroke (the most merest lifting) is combined with the finger 33 before it is wedged with each plate until it stops in a stack from the columns on one packet of the rasen 1, after which the upper plate is lifted. This difference in the magnitude of the scan 23 stops, and the bottom plate 22 continues to move up to the stop

The rooms of each finger 33 (the angle of rotation of the valve 30) is different and for each candle 40, the lower surface of the upper 45 ° pack (in the OK-H2 unit) is curled 23, as a result, Easter cakes 39 will be compressed (pressed in). Thereafter, the bottom plate will pass some more distance due to compression of the rubber seal 42 and some elastic deformation (tension) of the string 24 and deflection of the pallet 41.

Further movement of the right shoulder of the rocker arm 7 will cease, as there will be a balance between the force developed by the hydraulic actuator 9 and the resistance to the pressed package. In this position, the finger 33 of the valve 30 is again located on the path of the transfer

of the slider 14 (FIGS. 9 and 10), and the inclined shoulders 29 of the columns 26 are located above the screw surface 35 of the valves 30, which are in the right extreme position. Air supply in the right cavity of the pneumatic cylinder 12 moves the slider 14 to the left. In this case, the slide blocks 14 will engage with the fingers 33 (Fig. 10) and with further movement to the left, the valve 30 rotates around the axis 31 until the screw surfaces 35 with oblique shoulders 29 of the columns 26 are wedged, thereby fixing the bag in the pressed state. In this case, the rotation angle of all four valves will be different due to the fact that the inclined collars 29 of columns 26 are located at different heights from the screw surfaces 35 of the valves 30.

racks of the cart 18 (Fig. 11). Further movement of the grippers 5 downwards releases the T-shaped protrusions 28 of the columns 26, disconnecting the bag and repacking station by this, after which the cart 18 together with the bag is taken along the rails to the OK-I machine. When the bag is lowered, the sliders 14 are disengaged from the fingers 33 of the valves 30 (Fig. 11) and the sliders 14 by means of pneumatic cylinders 12 are moved to the leftmost position (Figs. 2-5 and 12), i.e. occupy the initial position in the position of waiting for the arrival of the next package for wedging (repressing).

The present invention allows to improve the operational properties of the repacking point due to the mechanization of the operations of fixation and unfolding of candle packages with the complete exception of manual labor.
