- the punch press 76 has a drive 77.
- This drive 77 may, as is well known to those skilled in the art, comprise an electric motor having a crankshaft or a shaft with eccentric discs.
- This crankshaft or eccentric disc is in drive connection with a connecting rod 78.
- a plunger 79 is articulated.
- the plunger 79 carries an upper tool 80, which is thus moved up and down in operation of the punch press 76.
- the upper tool 80 is equipped with machining tools, e.g. Stamp 81 equipped. Further, the upper tool 80 is equipped with gripping pins 82, each having a conical head portion 83.
- the catch pins 82 moved into pre-punched holes in the blank 11 in order to precisely center this.
- the upper feed roller 8 is briefly lifted by the lower feed roller 10 by a small Strekke, so that no clamping force is exerted on the band-shaped blank 11. This position of the upper feed roller 8 is referred to as insectslmontsburg.
- the control device of the entire feed device ie for all drives thereof, is generally designated by the reference numeral 86.
- control devices 85, 86 of the feed device and the punch press 76 communicate with one another, since the operation of the feed device must be coordinated with the operation of the punch press 76.
- the positions of the schematically illustrated parts of the feed device are shown during continuous operation.
- the first, upper feed roller 8 and the second, lower rotate Feed roller 10 which are driven by the servo motor 2 ago intermittently, so that the band-shaped blank 11 as is well known, is gradually advanced.
- the (electronic) control device of the feed device cooperates with the (electronic) control device of the punch press 76, see FIG. 10.
- the punch press 76 has a moving upper tool 80 and a stationary lower tool 84.
- the upper tool 80 is connected to a plunger 79.
- the plunger 79 is driven by a rotating drive 77, such as electric motors and crankshaft or eccentric shaft, via a connecting rod 78, wherein the connecting rod 78 purely schematically represents the drive connection between the drive 77 and the plunger 79.
- the plunger is movable between a top dead center position and a bottom dead center position.
- the thickness of the strip-shaped blank 11 and, correspondingly, the distance between the first, upper feed roller 8 and the second, lower feed roller 10 when they rest on the blank are indicated in FIG. 7 by the letter E.
- the upper feed roller 8 In order to insert a new strip-shaped blank 11, so for example a metal strip between the first, upper feed roller 8 and the lower feed roller 10, the upper feed roller 8 must be raised so that it has a predetermined distance D from the second lower feed roller 10 which is greater than the distance E. This distance D and the raised position of the first, upper feed roller 8 are shown in FIG.
- This position of the first, upper feed roller 8 is referred to in the art as a high-lift position (Fig. 8).
- the control devices 86 and 85 of the feed device and the punch press 76 are actuated such that the Plunger 79 of the punch press is located from the bottom dead center position and that the connecting rod 45 (FIG. 2) is away from the top dead center position.
- the advancing device and punch press controls 86 and 85 are actuated such that the ram 79 of the punch press 76 is in the top dead center position and the connecting rod 45 is in the bottom dead center position. The following description is based on these latter dead center positions.
- the bolt 43 is due to the force exerted by the compression spring 72 via the rocker 14 and the lever devices 40 and 52 at the lower end of the elongated hole 44 at.
- the upper feed roller 8 For continuous operation, the upper feed roller 8 must rest on the band-shaped blank 11, wherein by the first, upper feed roller 8 and the second, lower feed roller 10 a clamping force for a frictional engagement on the band-shaped blank 11 must be exercised.
- This clamping force is generated by the compression spring 72. So the bolt 43 may no longer rest on the lower end of the slot 44.
- the adjusting nut 39 is lowered by rotating the threaded spindle 30 from the high-lift position until the first, upper feed roller 8 rests on the band-shaped blank 11.
- the first double-armed lever 40 is forced to perform a pivoting movement, since the rocker stops moving because the first, upper feed roller 8 is supported by the compression spring 72 on the band-shaped blank 8 resting.
- Said pivotal movement causes the first arm 41 to pivot upward with the bolt 43, so that the bolt 43 is located in the slot 44 between its ends. This means that the connecting rod 45 can in principle perform lifting movements, without an action on the pin 43 takes place.
- an upper tool 80 of a punch press can be equipped with gripping pins 82 for precise positioning of the strip-shaped blank 11.
- the ribbon blank 11 must be exposed for a short period of time. This means that the first, upper feed roller 8 has to be briefly lifted off the band-shaped blank 11 in an intermediate release position.
- This intermediate release position is effected by the connecting rod 45.
- the stamping press 76 is moved into the lifting position, in which the intermediate ventilation should take place and in which position the conical head sections 83 of the gripping pins 82 are partially retracted into the positioning holes. This position can be seen in FIG.
- the plunger 79 of the punch press 76 is in an angular position before the lowest dead center position. Between this angular position and the bottom dead center position thus an angular distance is present.
- the connecting rod 45 of the feed device has now been simultaneously moved up by the actuation of its drive motor 48 in a position before its top dead center position.
- This angular position and the top dead center position.
- the angular distance referred to in connection with the punching press is equal to the angular spacing present in the feeding device.
- the adjusting nut 39 is moved downward by rotating the threaded spindle 30.
- the adjusting nut 57 is then moved further downwards, so that due to the now occurring pivotal movements of the lever devices and the rocker 14, the first, upper feed roller 8 releases the band-shaped blank. In this released state of the band-shaped blank is manually detectable loose.
- This position of the adjusting nut 39 is stored together with the respective angular positions in the control devices 85 and 86.
- the connecting rod 45 can move freely with the slot 44 relative to the bolt 43, without the bolt is affected, with the exception that when the connecting rod 45, the above angular position before the top dead center of the connecting rod 45th reached, the lower end of the elongated hole 44, the bolt 43 engages, lifts him and After the top dead center position has been passed through, the bolt 43 is released again.
- rocker 14 is arranged on one side, cantilever-shaped, can be built by two of the feed devices described a twin feed device by two such feed devices are arranged facing each other with respect to the feed rollers.
- FIG. 1 A first embodiment of a twin feed device is shown in FIG. 1
- Figure 12 shows an embodiment of a twin feed device used for extreme bandwidths. Again, the units corresponding to Figure 1 are identified with the letters A and B.
- the wide metal band 11 is taken at both longitudinal edges by the corresponding feed rollers of the feed devices arranged facing each other, which feed devices obviously operate synchronously.
