Definitions

  • the invention relates to a device of the type mentioned in the preamble of claim 1.
  • Such a device is used to receive the sheet to be printed, to feed it to the printing unit line by line and to bring it back into a removal position.
  • Vibratory drives represent very simple mechanical assemblies which make it possible to achieve the opposite movements of the slide with a drive motor rotating in one direction of rotation, as will be explained in more detail further on.
  • the drive motor is also used to actuate the actuating means for releasing the clamping when the carriage is in its initial position in which the sheet can be inserted or removed.
  • the construction according to the invention accordingly enables a fully automatic clamping, drawing in and pushing out of the sheet for the printing process with a single drive motor, which can also be the drive for the actual printing device, as is also explained in more detail.
  • the oscillating drive has at least one oscillating toothed segment which engages in at least one toothed rack formed on the slide.
  • the oscillating drive has at least one oscillating toothed segment which engages in at least one toothed rack formed on the slide.
  • two toothed racks running parallel to one another are preferably provided, each of which is assigned a toothed segment.
  • the slide is provided with at least one leaf spring bearing against a bearing surface of the slide as a clamp for the form and that a lifting pin is arranged on the leaf spring, which extends through a hole running from the rear of the rack into the toothing area protrudes into a tooth space and is displaced by a tooth of the toothed segment in the position corresponding to the initial position of the slide in the sense of lifting the spring. If the form is pushed out to its initial position after printing, the clamp is released in this way and the form is released for removal.
  • the oscillating drive is coupled via a control gear to a drive motor rotating in one direction of rotation.
  • the control gear comprises a cam disc with a closed, approximately heart-shaped control cam, wherein a control pin connected to a rocker arm engages in the cam and the rocker arm is fastened to a rocker shaft which is connected to the rocker drive of the feed device.
  • the control curve has two separate areas, namely a first area corresponding to the retraction movement of the slide and a second area corresponding to the pushing-out movement of the slide, which are run through in succession during each printing process.
  • the cam disc rotates continuously until the carriage is in its lower, fully retracted position.
  • the push-out movement takes place discontinuously from line to line and back to the starting position.
  • a tooth of the toothed segment presses on the lifting pin and in this way releases the clamp so that the form can be removed and a new one inserted.
  • the oscillation axis which carries the toothed segment
  • the cam disc carries a cam which interacts with the end of the oscillation axis on the curve side and which displaces it at least at the beginning of the first region of the control curve in such a way that the toothed segment provides the lifting pin the leaf spring releases. Only after the lifting pin has been released does the slide move in.
  • the control gear comprises a coupling device, via which the control gear can be coupled to the existing motor drive of the pressure device.
  • the Coupling device is preferably designed as a wrap spring clutch. This is structurally very simple and therefore inexpensive.
  • a magnetic switch or the like is used to actuate the coupling device.
  • the control gear has a locking mechanism, the locking mechanisms in each case corresponding to certain line positions of the feed device or of the form.
  • the locking pawl of the locking mechanism can also be actuated by the magnetic switch in such a way that the locking pawl disengages when the coupling device is engaged.
  • the magnetic switch By actuating the magnetic switch, the locking mechanism is released at the same time and the clutch is engaged, so that the control gear and the carriage connected to it perform the intended movement.
  • the clutch is released and the control gear is stopped precisely by engaging the pawl in one of the line positions provided.
  • an electronic control device is provided according to the invention, which in turn can be controlled by the signal transmitter.
  • the printing device shown in Fig. 1 has an essentially conventional basic structure.
  • the form receptacle 6 is located between two side chassis walls 2 and 4. In the present case, this is essentially formed by a rear wall 8 and the platen roller 10.
  • the form lies with the side to be printed against the rear wall 8, which is broken through in the area of the platen roller 10 for the passage of the printing unit, not shown here.
  • a stop 12 on which the form rests is used for precise line adjustment of the form.
  • the height of this stop 12 can be adjusted via a latching device 14, so that different row heights can be set. This adjustment of the stop 12 need not be described in more detail here; However, it can be seen that the process is cumbersome, since the cover of the device, which is not shown in more detail here, has to be removed.
  • Baffles 16 serve to facilitate the introduction of the form into the receptacle 6.
  • Swiveling stops 18 can be attached to the side surfaces 2 and 4, only one of which is shown. These each comprise guide plates 22 which can be pivoted about an axis 20 and which laterally close the receptacle 6 in a pivoted-in position, but in the position shown leave them open for accommodating wider forms.
  • a clamp described in more detail below detects the form, so that it moves with the carriage 26.
  • the carriage 26 is driven by two toothed racks 28, 30 formed thereon, in which toothed toothed segments 32, 34 each engage in a swinging manner. These toothed segments are fastened on an oscillation axis 36, which is rotatably mounted in the side walls 2 and 4 and is oscillatingly driven via an oscillation lever 38 in accordance with the arrow 40.
  • the oscillation axis 36 is also longitudinally displaceable in the direction of the arrow 42, so that the toothed segments 32, 34 are laterally displaced in the associated toothed racks 28, 30, but always remain in engagement therewith.
  • the rocker arm 38 is driven via the mechanical control gear 44, which in turn is connected to the drive 48 via the drive shaft 46.
  • Fig. 2 shows an enlarged view of the carriage 26, which is mounted in a conventional and therefore not shown manner in the direction of arrow 24.
  • the forks 50 are guided on a connecting rod 52.
  • the carriage 26 assumes its lower position in FIG. 2, in which the form 54 represented by a dashed line is completely drawn into the receptacle, so that the printing unit 56 can print the top line (the form has standard dimensions, so that the guide plate 22 can be pivoted into its folded down position 6 which laterally closes the receptacle).
  • the toothed segments 32 and 34 are pivoted back, the slide 26 is moved upwards, taking the form 54 with it. It is fundamentally possible for the form to be completely drawn into the receptacle first and printed line by line when it is pushed out.
  • the structure of the control gear 44 can be seen from Figures 3 and 4.
  • the entire transmission accommodated between two web walls 58, 60 is fastened to the side wall 4 by means of spacer bolts 62, 64.
  • a gearwheel 70 connected to a coupling shaft 68 engages in the pinion 66 connected to the drive shaft 46.
  • a wrap spring clutch 72 which can be actuated by a magnetic switch 74, is arranged on the coupling shaft 68. Through the wrap spring clutch 72, the clutch shaft 68 can be coupled to the gear 76, which rotates about an intermediate gear 78 transmits to another gear 80, which in turn is attached to the cam shaft 84.
  • the cam disk shaft 82 carries the cam disk 84, which is provided with a closed, approximately heart-shaped control cam 86.
  • the control cam 86 has a first region 90 which corresponds to the continuous retraction movement of the carriage 26, and a second region 92 which corresponds to the row-by-row push-out movement of the carriage and the associated form. If the cam disk 84 in FIG. 4 rotates in the direction of the arrow 95, the control pin 88 passes through the area 92. It takes the positions b, c, d and e one after the other, starting from the position a. Each of these positions corresponds to a print line. Position e also corresponds to the starting position of the carriage, at which the form can be removed and a new one inserted. When the cam 84 continues to rotate in the same direction of rotation, the control pin passes through the area 90, the rocking lever 38 being pivoted back into position a, that is to say the form is drawn in completely.
  • a ratchet mechanism 94 is provided on a part 96 connected to the driven part of the wrap spring clutch 72.
  • a locking toothing 98 is formed, in which a pawl 100 can engage.
  • the pawl 100 is rotatably mounted about an axis 104 via a lever 102 and is held in the locked position by a spring 106, which acts on a lever 108 connected to the lever 102 (FIG. 4).
  • the pawl 100 can be disengaged by the magnetic switch 74 against the force of the spring 106, so that the part 96 can perform a rotary movement.
  • the wrap spring clutch 72 and the pawl 100 are actuated simultaneously by the magnetic switch 74 such that the pawl is disengaged when the clutch is engaged.
  • the wrap spring clutch has a 4x90 ° locking pitch; switching through 90 ° corresponds in each case to a movement of the rocker arm 38 from one position (a, b, etc.) to the next, so that after a revolution of the part 96, the positions from a to e are run through. Accordingly, a further 90 ° switching movement of the part 96 is required to pull in the slide.
  • a cam 110 is arranged on the side of the cam plate 84 which faces the oscillation axis 36 and which cooperates with the end of the oscillation axis 36 or the dome-shaped oscillating lever 38 fastened thereon.
  • the oscillation axis 36 is displaced against the force of the compression spring 112 each time the control pin 88 passes through the region designated by a in FIG. 4.
  • the area a is characterized in that here the control cam runs concentrically to the cam disk axis 82, so that the rocking lever 38 does not move, but remains in its position corresponding to item e.
  • a clamp formed by one or more cranked leaf springs 114 is arranged on the slide 26.
  • a lifting pin 116 is fastened to each leaf spring and projects through a hole running through the toothed racks 28, 30 into a tooth gap 118.
  • the toothed segments are displaced laterally to such an extent that they release the lifting pins 116 and the leaf springs 114 return to their clamping position due to their own spring force, so that the form 54 is retained.
  • the slide 26 does not yet move, since the control pin 88 passes through the concentric control cam region a, as described above.
  • the cam 110 again disengages from the rocker arm 38, the rocker shaft 36 and the toothed segments 32, 34 arranged thereon return to their normal position under the action of the compression spring 112.
  • the entire device is controlled in such a way that a signal generator 120, for example a mechanical sensor or a light barrier, reports that a form has been inserted and emits a corresponding start signal.
  • An electronic control device 122 controls the pressure cycle by repeatedly energizing the drive 48 and the magnetic switch 74, which in turn actuates the wrap spring clutch 72 and the ratchet mechanism 94.
  • the signal generator 120 can be arranged on one of the guide plates 16 and e.g. be designed as a light barrier.
