Definitions
- the invention relates to a folding blade drive for a folding machine, with a Folding sword, which at one end of a pneumatic lift drive for an up and down movement driven drive rod is attached, the pneumatic stroke drive a cylinder and one movable up and down in the cylinder Piston covers.
- a folding sword drive is known, on the drive rod a piston is attached, which is guided in a suction cylinder is.
- a suction line is connected to the suction cylinder, which passes through a back and forth movable shut-off valve can be opened or shut off.
- the shut-off valve is connected to a sniffer flask, which is in a sniffer cylinder is guided up and down movable.
- the sniffer flask is moved up when a nozzle provided just before an arc stop is covered by an arc becomes.
- the shut-off valve is opened, which in the suction cylinder in Vacuum is generated, which moves the folding sword down.
- the drive rod is moved back to the starting position by a return spring.
- DE-PS 628 026 describes a folding sword drive in which the folding sword is connected to the piston of a sniffing device, which when closing a control suction opening through an arc brought up to a front stop due to a voltage generated in a suction line together with the Folding sword is moved so that the folding sword is the sheet between folding rollers strikes.
- EP 0 987 210 A2 discloses a folding sword drive in which the folding sword at one end one by a pneumatic lift drive for an opening and closing Movement driven drive rod is attached.
- the pneumatic The linear actuator is located via a suction line and a switching valve with a vacuum generator so connected that the actuator stem with the switching valve open is moved down by negative pressure. There is also a return stall provided that the drive rod moves up when the switching valve is closed.
- the invention has for its object a structurally simple means To create folding sword drive, which ensures an exact folding of a sheet.
- the piston can be moved up and down of the folding blade are each subjected to excess pressure. There are therefore very high pressures possible, which results in a high folding blade speed is achieved. This increases the folding quality.
- the valve device preferably has a first switching valve and a second one Switch valve on, the first line via the first switching valve with the positive pressure generator is connectable, and the second line via the second switching valve can be connected to the pressure generator
- a 5/2-way valve can also be used as the valve device.
- the folding sword can with even higher Speed are moved, so that an exact sheet transfer is guaranteed becomes.
- the switching valves it is possible to change the speed of the folding sword to control conditionally. If, for example the switching valves are switched before the piston reaches its respective end position reached, it is possible to impact the piston without additional damping elements to reduce, which greatly reduces the noise is reduced.
- the switching valves can preferably be switchable in such a way that the first line is connected communicates with the negative pressure generator when the second line is connected to the positive pressure generator is connected, or the first line to the positive pressure generator communicates when the second line is connected to the vacuum generator is.
- a control device can be very simple for a corresponding control be constructed.
- the switching valves are formed by solenoid valves with a control device connected, it is possible to switch the solenoid valves so that an optimal speed curve is achieved.
- Damping elements can be used above and below the piston for shock absorption be provided, which surround the piston rod.
- the folding blade drive 10 shown in the figure comprises an upper housing block 12 and a lower housing block 14 between which a drive cylinder 16 is arranged.
- a drive rod passes coaxially through the drive cylinder 16 18 through, which extends through the upper housing block 12 and through the lower Housing block 14 extends, and is guided in these in slide bearings 20 and 22, respectively the play between the drive rod and the respective slide bearing 20 or 22 Is 0.015 to 0.1 mm.
- a folding sword 24 is arranged at the lower end of the drive rod 18 .
- the upper and lower sides of the piston 26 each border Damping element 32 or 34, which the impact of the piston 26 in the end positions attenuates.
- the upper housing block 12 has a vertical end at its right end in the figure Pad 40 on.
- An upper horizontal bore opens into the connection surface 40 42 and a lower horizontal bore 44 which in the upper housing block 12 are formed.
- a Connection nipple 46 for connecting a vacuum device (not shown) screwed
- a connecting nipple 48 for connection of an overpressure device (not shown) is screwed in.
- Each solenoid valve 52, 54 has a valve body 56 or 57 on, in which a valve piston 58 or 59 is arranged coaxially, wherein each valve piston 58, 59 in the direction of a corresponding valve spring 60 or 61 of the valve connection surface 50 is prestressed such that the piston 58 or 59 abuts the valve connection surface 50 when the solenoid valve 52 or 54 is not is operated.
- the valve pistons 58, 59 are each surrounded by a valve chamber 62, 63 surround.
- first connection bore 68 is provided which is in line with the lower horizontal bore 44 communicates and below the valve piston 59 in the Valve connection surface 50 opens.
- second connecting bore 70 is formed, which is connected to the upper horizontal bore 42 communicates and below the valve piston 58 in the Valve connection surface 50 opens.
- a connection line 72 is also provided, the one end of which on the valve connection surface 50 next to the second Connecting bore 70 in the valve chamber 62 of the solenoid valve 54 and with it the other end opens into the cylinder base 36 below the piston 26.
- Another Connection line 74 opens at one end next to the first connection hole 68 on the valve connection surface 50 in the valve chamber 63 of the solenoid valve 52 and with its other end in the cylinder roof 76 of the drive cylinder 16 above the piston 26.
- the end facing away from the connecting nipple 46 the upper horizontal bore 42 is connected via a connecting line 78 to the Through opening 64 of the solenoid valve 52 in connection, while the connection nipple 48 opposite end of the lower horizontal bore 44 via a further connecting line 80 is connected to the through opening 65.
- the solenoid valves 52, 54 are connected to a control device via contact devices 82, 84 (not shown) electrically connected.
- the folding sword 24 is shown in its uppermost position, in which also the piston 26 is in its uppermost position. In this position they are Solenoid valves 52, 54 are not actuated, so that the valve pistons 58, 59 on the valve connection surface 50 and close the connection bores 68, 70.
- the overpressure generator (not shown) connected to the connection nipple 48 via the lower horizontal bore 44, the connecting line 80, the through opening 65, the valve chamber 62, and the connecting line 72 with the space of the working cylinder 16 below the piston 26 in connection.
- connection nipple 46 connected vacuum generator (not shown) is above the upper horizontal bore 42, the connecting line 78, the through opening 64, the valve space 63 and the connecting line 74 with the space of the working cylinder 16 above of the piston 26 in connection, so that the piston 26 through the under it existing overpressure and the overpressure present above it in its uppermost End position is held.
- two switching valves 52, 54 are used as valve devices used. However, it is also possible to replace the two switching valves to use a 5/2 way valve.
- sufficiently good folding speeds can also be achieved be when the piston 26 for movement in the two end positions only with Overpressure is applied to the corresponding pages.
- a vacuum generator can be dispensed with.
