2 and the bottom 3 roll feeds for moving the strip or belt to the area of the punch die 4, the correct 5 and the winding 6 with the expanding device 7, the folding table 8, the device 9 for lifting, moving the laying on the folding top of the lanes, loading trolley 1C for rolls with a device 11 for centering the rolls, a control panel 12 for controlling the installation of a roll and charging the end of the belt 12, a freely programmable controller 13 and a main control 14 for controlling the system.

The pusher 2 and t nusha 3 roller feeds are installed at the cutting position of the press machine 1. Each of them has (Fig. 2) a lower and upper shaft 20 ki. The lower roll is placed in a stationary housing 15, and the upper roll is in two cheeks 16 connected by an axis 17 with the housing 15. The upper roll with cheeks 16 is pressed against the lower roll by a pneumatic 25 cylinder 18. If the rolls have an entom or strip, then the upper roll it is raised by its thickness, and the cheeks are rotated at a certain angle (pas 2 is shown by dotted line). Sensors 19 and 20 are mounted on housings 15–30, flags 21, which interact with these gauges, are mounted on swiveling cheeks 16. The roller of the bottom feed 3 has an annular groove 22 in the middle, in which there is a stripper of the remainder of the strip or belt, consisting of a horizontal pneumatic cylinder 23 with a rod 24 with a spring-loaded pawl 25. The pushing and pulling roller feeds are kinematically connected with drive (not shown) of the automatic press, for example by means of levers and overrunning clutches (not shown). Moreover, on the lower rollers, the hubs of the 45 additional overrunning clutches (not shown) are fixedly mounted, and their clips interact with the rods of the pneumatic cylinders 26 of the mechanisms of the additional rotation of the rolls. Between the pushing and pulling shaft- feed feeds, a cutting die 4 is installed along the cutting position axis.

The turntable (Fig. 3) is made in the form of guides 27 mounted on brackets 28, mounted cantilever on the horizontal axis 29. Pneumatic cylinder 30 with its stem interacts with lever 31, which is fixed on axis 29. Pneumatic cylinder 32, on the rod of which is fixed the gripper 33 in the form of an adjustable stop, intended to move the strips during refueling in a roller feed. On the guides 27, a sensor 34 of the front position of the gripper 33 is mounted. The gripper 33 is a sliding setting element.

A device 9 for lifting, moving perpendicularly to the feed direction and laying on the turntable of strips (Figs. 1 and 3) consists of a movable carriage 35 driven by a horizontal pneumatic cylinder 36 and pneumatic cylinders 37 installed on it, with the vacuum clamps 38 fixed on the rods. 35 is moved on columns 39 fixed to frame 40, on which is also installed a cassette 41 with a bundle of strips. The extreme positions of the carriage 35 are controlled by sensors 42 and 43. The cylinder 44 moves the piston of the vacuum cylinder 45, the cavity of which is connected to the vacuum grippers 38. The sensor 46 monitors the position when vacuum is created in the grips 38, i.e. vacuum cylinder piston down. The sensors 47 control the lifting of the suction cups in the presence of vacuum in the suction cups (the signal from the sensor 46). The unwinding device 6 serves to install a roll of tape on its expanding mandrel 7 (FIG. 1). The mandrel is driven by an electric motor. A pressure roller 48 (Fig. 4) is provided to prevent flaking of the roll, which can be rotated by means of a pneumatic cylinder 49.

The bent end of the roll tape is mounted on an axis 50 fixed on the body of the correct device 5 (Fig. 4) and consists of a pneumatic cylinder 51 fixed on the body of a correct device, a guide 52 connected at one end to the axis 50, and the second pivotally with a rod of the pneumatic cylinder 51 a pneumatic cylinder 53 fixed on a guide 52, a movable guide 54 moving along the surface of a naphap 52, by means of a pneumatic cylinder 53, a scraper 55 connected by a single axis to the movable guide 54 and with a rod of a pneumatic cylinder 53.

The upper roller 56 of the correct device can be pressed against the lower

double action 57. The rise of the upper roll is monitored by a sensor 58, which is connected via a program-controller-scooter in the control circuit of the motor of the mandrel of the unwinding device. The control lever 59 of the size of the belt loop between the correct device and the roller feed 2 (Fig. 1) is driven by the pneumatic cylinder 60 and can be raised to the position indicated by the dotted line or released and lowered freely down depending on the size of the belt loop. The sensors 61 and 62 are designed to signal the switching on and off of the electric motor of the correct device at the maximum and minimum size of the tape loop. The loading trolley 10 for rolls (Fig. 1) is used to set in height and move the roll of tape installed before it to the expanding mandrel 7.

The console 12 serves to control the installation of the roll and to feed the end of the tape into the roll feed of the automatic machine 1. The main console 14, located on the press machine, serves to control the entire complex. A freely programmable controller 13 on microprocessors performs the role of a control circuit, and the data on the interaction of the mechanisms are entered into it using a programmer (not shown).

The gripper 33 is fixed on the rod 82 5 of the cylinder 32 with the possibility of adjusting movement along it to move along the guide plate 83. The dogs 25 are spring-loaded with springs 84.

Position 85 designates the cassette at the initial position, 86 - the cassette without material, 87 - the receiver (roller), electrical connections 93 - the rod.

Work from the roll tape originated

The roll 63 is placed on the table 64 25 dit as follows (Fig. 5), which is adjusted in height with the help of screw and screw gears so that the axis of the roll coincides with the axis of the mandrel 7 (Fig. 1). The alignment of the axes is achieved with the help of 30 mechanism 11 (Fig. 1), which is made in the form of two rack gears, gears 65 and 66 of which with a ratio of diameters of 2: 1) are mounted on the same axis 67 of the housing 68 fixed to the bracket 69 mounted on the housing carts 70. Driven gear rack 71 is engaged with small gear 66. At the lower end

On the lift table 64 of the loading carriage 10, a roll of tape is installed so that it appears in the sector formed by the pressure roller 48 and scraper on the end of the tape 55 (Fig. 4). Then, pressing the button on the remote control 12 includes the Roll installation program. From the commander 5 of the controller 13, a command is given to the air distributor (not shown) of the air motor 77 and the lever 76 is turned in the horizontal plane to the position Above the roll. The closure 71 closes the flag 72, which acts 4o with the sensor circuit 78 and sends a signal to the sensor 73 mounted on the air distributor (not shown) on the bracket 69.

The drive rack 74, which is in engagement with gear 65, is connected to a rod of a pneumatic cylinder 75 mounted on a table 64.

The lever 76 is connected to the casing of the half-rotary air motor 77, the shaft of which is fixed to the rod of the pneumatic cylinder 75. On the rod of the pneumatic cylinder 75 on the radial bracket there is a sensor 78t which is attached to the flag 79, which is rigidly connected to the body of the pneumatic engine 77.

Limiters 80 on the expansion frames 55 than the stroke of the rail 74. Since all system 7 serves to prevent us from being set up in such a way that the edges of the ribbon creep from the mandrel are lower than the lower position of the table 64, the edge of the shears 81 are intended for higher position lever 76 and shredding waste (cut ribbon). flag 72 in the sensor slot

In this case, the cylinder rod 75 moves the rail 74 downwards, and it by means of gear 65, roller 67 and gear 66 lowers rail 71 by an amount two times smaller than Hopsm of rail 74 (since the diameters of the initial circles of gears 65 to 66 correlate as 2: 1).

On the lift table 64 of the loading carriage 10, a roll of tape is installed so that it appears in the sector formed by the pressure roller 48 and scraper on the end of the tape 55 (Fig. 4). Then, pressing the button on the remote control 12 includes the Roll installation program. From the controller 5 of the controller 13, a command is given to the air distributor (not shown) of the air motor 77 and the lever 76 is turned in the horizontal plane to the position Above the roll. It closes the sensor circuit 78 and sends a signal to the air distributor (not shown).

The distance between the sensor 73 and the flag 72 when installing a roll of smaller size is equal to the difference of the radii of these rolls (value, Fig. 5). Simultaneously with the team l, (

the lowering of the unit (with a delay of JQ each other. With the same activation signal) a command is given to turn on the electric motor for raising the table 64, which moves up to the flag 72 with the sensor 73, i.e. to align the axis of the installed shaft - J5 with the axis of the expanding mandrel 7 (Fig. 1). After that, a giggle comes in to enable the motor to move the loading car 10 K expanding mandrel, which Q moves until the axis of the tape roll coincides with the cutting axis of the press automaton 1, which is limited by a sensor (not shown) mounted on rails the carriage 10 moves. 25 From it, the control circuit gives commands to retract the lever 76 from the roll and return it to its original position to lower the table 64 and the carriage 10, which leaves 30 from the expansion mandrel 7 and returns to its original position the position, as well as the air diffuser of the mandrel 7, the cams of which are consumed, unclamping the roll. The same air distributor with the help of the pneumatic cylinder 49 presses the roller 48 to the roll, which prevents the roll up of the roll. This completes the roll installation program .40

The cutting of the ribbon tying coil and the installation of the stops 80 (Fig. 1) in a vertical position is done manually.

Then the matched corresponding. 45 buttons on the remote control 12 include the program Automatic ribbon filling. In this case, the software controller 13 (Fig. 1) outputs a signal to an air distributor (not shown) supplying compressed air to the pneumatic cylinders 51 and 53 (Fig. 4) of the bend end of the tape, which is pressed to the roll by the pointed end of the scraper 55. At the same time, compressed air is fed into top ,,. the cavity of the pneumatic cylinder 60, which rotates the control lever 59 and it is above the level of movement of the belt, into the upper cavity of the pneumo35

The motor of the correct device 5 (Fig. 1 and 4), the correct driver and pull rolls start to rotate (lower clockwise, upper against, Fig. 4), simultaneously a variable signal is sent from the program controller 13 to the air-distributing bodies of the pneumatic cylinders of the cylinders. rolls 26 (Fig. 2) and air are fed alternately into the upper and lower cavities, so that the rolls receive a periodic rotational motion at a certain angle (lower counterclockwise, upper clockwise, fig. 2). Thereafter, the software controller issues a second signal — the expanding mandrel motor 7 is turned on (Fig. 1) and it is rotated with the roll clockwise on it (Fig. 4). At the same time, the end of the belt slides along the bending tool - the scraper 55 (Fig. 4) and when approaching the setting rolls 56 is pulled in by them (they rotate), the upper roll rises by the thickness of the tape, and the sensor circuit 58 (Fig. 4) breaks - electric the motor of the mandrel 7 of the unwinding device is switched off. Next, the tape is moved by the correct device. On leaving it, the end of the belt slides along the guides 27 (Fig. 3) of the folding table 8 (Fig. 1), and is tightened by rollers of the pushing 2 roller feed (Fig. 1, 2), with the upper roller rising by the thickness of the tape, and the flag 21 breaks the circuit of the sensor 19. At the same time, the control unit, having received information from the sensor 19 on the pushing roller feed 2, gives a signal to retract the scraper 55 (FIG. 4) from the roll and lower the guides 52 and 54 of the tape end, to lower the folding table 8 (Fig. 1) with guides 27 (Fig. 3) and the control lever 59 (Fig. 4) to the original (lower) polo ix.

The motor of the correct device 5 (Fig. 1 and 4), the correct driver and pulling rolls begin to rotate (lower clockwise, upper against, Fig. 4), simultaneously a variable signal is sent from the program controller 13 to the air distributors of the pneumatic cylinders of the additional rollers of the rollers 26 (FIG. 2) and the air is alternately supplied to the upper and lower cavities, so that the rolls receive a periodic rotational motion at a certain angle (lower counterclockwise, upper clockwise, fig. 2). Thereafter, the software controller issues a second signal — the expanding mandrel motor 7 is turned on (Fig. 1) and it is rotated with the roll mounted on it clockwise (Fig. 4). At the same time, the end of the belt slides along the bending tool - the scraper 55 (Fig. 4) and when approaching the setting rolls 56 is pulled in by them (they rotate), the upper roll rises by the thickness of the tape, and the sensor circuit 58 (Fig. 4) breaks the motor of the mandrel 7 of the unwinding device is switched off. Next, the tape is moved by the correct device. On leaving it, the end of the belt slides along the guides 27 (Fig. 3) of the folding table 8 (Fig. 1), and is tightened by rollers of the pushing 2 roller feed (Fig. 1, 2), with the upper roller rising by the thickness of the tape, and the flag 21 breaks the circuit of the sensor 19. At the same time, the control unit, having received information from the sensor 19 on the pushing roller feed 2, gives a signal to retract the scraper 55 (FIG. 4) from the roll and lower the guides 52 and 54 of the tape end, to lower the folding table 8 (Fig. 1) with guides 27 (Fig. 3) and the control lever 59 (Fig. 4) to the original (lower) polo ix.

Scraper 55, guides 54 and 52 of the stubby tape, table 8 with its pneumatic cylinders 27 guides down immediately, and control lever 59 with some delay (because it descends only under its own weight, but in the cavity of its cylinder 60 there is a throttle and the air is released slowly). The roller of the control lever 59 is lowered onto the belt, which at this moment is located

horizontal position. Since the tape is moved by the rollers of the correct device 5 (Figs. 1 and 4) at a higher speed than by periodically turning the rolls of the bottom and 15 pushing feeds, between the device 5 and feed 2 a loop is formed downward from the horizontal, followed by the lever 59 The tape moves through die 4 (Fig. 2) and is pulled down by 20 rollers of the underflowing feed 3, the upper roller rising by the thickness of the tape, and the flag 21 breaks the sensor circuit 20. As soon as the flag 21 (Fig. 2) breaks the sensor circuit 20 , to the command- the controller 13 issues a signal also on the terminate periodic alternate supply of compressed air in the cavity of the pneumatic cylinders 26 of the mechanism of additional twisting of the rolls of the pushing and pulling feeds 2 and 3 (Fig. 1 and

the formation of a sufficient size of the compensation loop (information about this to the commander comes from the sensor 61 (Fig. 4) of the lower position of the control lever) .40

This completes the automatic ribbon feeding program.

Pressing the Work from the ribbon button, the machine on the main control panel turns on the press machine. The kinematically connected roller feeds 2 and 3, which are connected with its drive, periodically move the belt. The cutting slider (not shown) of the press machine moves the punch of the cutting punch 4, piercing the cut in the belt, the cut-through billet falls down and is transported to the forging positions with a clamshell feed. As the ribbon moves, its loop between roller feed 2 and the correct device 5 decreases, and the control lever 59 rotates. When approaching the extreme upper position, it closes the sensor 62, which gives a signal to turn on the motor of the correct device 5. The correct rollers of the device begin to rotate, right and moving the belt. Since the belt moving speed of the device 5 is set somewhat higher than the roller feeds, the loop again gradually increases until the motor of the correct device is turned off. This continues throughout the stamping process until the end of the roll. When the end of the tape comes out of the rolls of the correct device, the lever 59 is lowered down, turning off its electric motor. When the belt has been used up and the end of it comes out of the pushing rolls 2, the upper roll lowers to its thickness until it comes into contact with the lower roll. When this flag 21 on it closes the sensor 19 and the controller 13 outputs a signal to the pulse counting relay (RSI), which counted the required number of strokes of the automatic press (feed steps 3), will turn on the mechanism 3 additional feed spin - the tape will move with the enlarged y step at a time when the end of her l & whale on the die die 4, which will prevent incomplete logging in the tape. Then, the remainder of the ribbon from the cutting punch 4 moves with a normal pitch until it comes out of the bottom supply rolls 3. When this happens, the flag 21 on the supply 3 closes the sensor 20, through the controller 13 the command will go to the air distributor (not shown) dropper tape residue. His cylinder 23 will move the rod 24 with the dog 25 to the left along the belt. Dog 25 will hit the end of the tape. And} since it is located in the annular groove of the lower roll and can move beyond the axis of the rolls to the left along the belt, throws it (the remainder of the belt) behind the scissors. This eliminates the need to remove the remainder of the belt between the manual and roller feed and the scissors manually. The same sensor 20 gives a signal to stop the drive of the automatic press 1. The punching of the booth is over. Further work from the next roll is performed in the same order.

The work of the complex on the strip material is as follows.

Pressing the Work Band button, the machine on the main panel 14 turns on the drive of the press machine 1 ". The kinematically associated feed rolls 2 and 3 begin to rotate periodically. Press the power button on the supply of the strip on the remote control unit 12 of the complex. In this case, the compressed air enters the upper cavity of the pneumatic cylinder 30 (Fig. 3), which turns the table 8 (Fig. 1) with guides with its rod and lever 31. 27 (FIG. 3); the horizontal position in which it remains for the entire duration of the operation of the strip. The controller 13, instructing the signal from the sensor 19 pushing Dodaci 2, which is closed, because there are no stripes in the Beams, and the upper roller is lowered, issues a command to switch on the distributor (not shown), v the compressed air enters the upper chambers of the cylinders 37 (FIG. 3) - vacuum suckers are lowered down to the contact with the strip in the cassette 41. From the same team (but with a delay for lowering the suction cups), an air distributor (not shown) is turned on, supplying compressed air to the upper cavity of the cylinder 44 - There is a vacuum cylinder piston. ndra 45, suction air from the pri- foeov 38. The band captured. After creating a vacuum in the suction cups, i.e. after capturing the strip, the sensor 46 will give a signal to the control unit 13, from where a command is given to the air distributor of cylinders 37 — the suction pumps with the strip rise upwards, closes the sensor circuit 47, from which it sends a signal to turn on the air diffuser supplying compressed air to the pneumatic cylinder 36. Pneumatic cylinder 36 moves the carriage 35 with suction cups holding the strip to the position

Above the folding table 8, in which the barge closes the sensor 42. All three signals (from sensors 46, 47 and 42) are transferred to the controller 13 and are converted into a signal of the position of comicity. At this moment, the upper supply roll 2 is in contact with the lower one, and the sensor circuit 19 is closed (if the previous strip already exists in the rolls, then the sensor 19 is closed at its exit from the rolls - the automatic press works). Upon receipt of the signal from sensor 19 and in the presence of a ready position, the controller 13 outputs

a command to the air distributor of the cylinder 44, and the piston of the vacuum cylinder 45 will move to its original position (down) - air from its cavity is fed into the cavities of the vacuum suction cups, the strip is detached from them and the folding table drops (guides 27) - Resetting the strip. Upon receipt of the signal from the sensor 19 and in the presence of a ready position, the commander 13 also issues (with a small delay) a command to raise the upper roll of the pushing feed 2, as well as to move the gripper 33 by the pneumatic cylinder 32 of the slide mechanism to the rollers and the carriage 35 to the initial position . The gripper 33 moves to the rolls, a strip in the rear end, which enters the open feed rolls 2. Upon arrival in the extreme forward position, the gripper 32 closes the sensor 34, which gives a signal to the controller 13 Ready to lower the upper roll. In order to ensure the completeness of the first pitch, the feed rolls 2 must close at the moment when they do not rotate. A signal about this to the controller 13 comes from a sensor in the control unit of the automatic machine 1. By aligning the signal from this sensor to the ready position, the controller gives a signal to lower the upper roll. From this point on, the strip is moved by roller feeds 2 and 3, and the gripper 33 moves to its original position. In order to avoid incomplete punching at the moment when the end of the strip is on the matrix of notch stamp 4, the mechanism of additional twisting of rolls of the lower feed 3 is activated, the command to the air distributor of which comes from the controller 13 after processing the signals from the sensor 19 (when the end of the strip goes out of rolls), a sensor in the press command station (not shown) (signal that the rolls do not rotate

from the drive of the press machine) by counting a certain number of moves (steps) of the pulse counting relay (RSI). At the exit of the end of the strip from the rolls of the underflow feed 3, the sensor 20 on it sends a signal to the controller 13, from which a command is sent to the air distributor (not shown) of the belt remainder (strip). His cylinder 23 will move the rod 24 with the dog 25 to the left, along the belt. Dog 25 will strike the rest of the strip. And, since it is located in the groove of the lower roll and can move beyond the axis of the rolls to the left along the belt, throws it out of the roll housing 3 and scissors 81. As the strip leaves the pushing rollers 2, the controller 13 gives the next command to lower the suction cups stripe and the cycle repeats automatically.
