Definitions
- the invention relates to a sheet leading edge separator with several double suction cups arranged side by side for cyclical conveying von Bogen, the double suction cups by a cam coupling gear driven movements on a closed path in the conveying direction run the bow and back while doing the double suction in one movement cycle comprising two work cycles by one work cycle successively moves into the area of the leading edge of a stack of sheets get a sheet with a suction pad the cam coupling gear, on which a double suction cup is fixed, the suction coupling is articulated to two cam drives, so that the double suction cup can be moved essentially vertically and horizontally is drivable.
- Such a sheet leading edge separator is known from DE 42 20 399 A1. Because the cam mechanism of this well-known leading edge separator can only produce one vertical and one horizontal movement, this occurs during the lifting movement of the double suction device Tilting the double suction cup that its lower suction surface at its in Direction of conveying end is raised less than that in the conveying direction rear end. Due to this tilting movement, the lower suction surface is contrary to the extension of the double suction on the sheet stack drooping rear arch part inclined so that the bow can easily unintentionally detach from the double suction cup. This danger is particularly large for stiff sheets such as cardboard boxes, since the sheet is then also towards most of the weight of his over the sheet stack the conveying direction extending rear area a releasing Moment on the front area covered by the double suction cup.
- the object of the invention is therefore a sheet leading edge separator to create the type mentioned, which at least with a simple structure largely vertical lifting of the double vacuum cleaner at the same time defines stronger lifting of the front area in the conveying direction allows its lower suction surface opposite the rear area.
- This object is achieved in that the suction pad along a tilting movement of the double suction cup around itself horizontally transverse to the sheet conveying direction extending axis of the Double suction cup defining curve contour is guided.
- the both cam drives the vertical lifting of the double suction cup and thus a perfect slipping over the front edge of the sheet over one usually on the front edge of the stack.
- the course of the curve contour By choosing the course of the curve contour, the course of the Tilting movement can be determined.
- the curve contour can be part of the first Be cam gear.
- the first cam mechanism can be essentially horizontal have horizontal couplings which can be driven and moved horizontally, which is hinged at one end to the suction coupling, wherein advantageously the pivot axis of the articulation of the horizontal coupling forms the tilt axis at the suction coupling.
- the first cam mechanism can be used to generate the horizontal movement have a substantially vertically extending rocker which supported at one end region so as to be pivotable about a fixed pivot axis and is pivotable by a rotatable cam is drivable, the horizontal coupling with the double suction opposite end area at a distance from the first Swivel axis is articulated on the rocker.
- the curve contour can be fixed be connected to the rocker, preferably the curve contour extends approximately radially away from the pivot axis.
- the second cam mechanism has, in a simple embodiment, an essentially vertically extending coupling which can be driven approximately vertically movably by a second rotatable cam.
- the coupling can be articulated at one end to the suction coupling and at the other end from the second cam be acted upon vertically movable.
- roller rocker near the second cam on the coupling hinged.
- Another vertical guide can also be that the coupling articulated at one end to the suction paddle and at its second The end of a double-armed swing arm can be moved approximately vertically can be acted upon, the double-armed rocker around a second fixed Swivel axis is freely pivotable, with the free end of one Swing arm articulated at the second end of the paddock and one at the free end of their second swing arm freely rotatable second roller on the radial circumferential contour of the cam disc second cam mechanism is in plant.
- a particularly low-component construction and a particularly small installation space is achieved when the first and second cams on a common rotatably drivable drive shaft are rotatably arranged.
- the sheet leading edge separator shown consists of at least two spaced apart units, like one of them in figure 1 or 3 is shown.
- These units each have a double suction device 1 and 1 'on which an essentially horizontally extending suction coupling 6 is arranged.
- the suction coupling 6 is opposite to the double suction device 1 End in a guide 15 of a curve contour guided freely movable.
- the Guide 15 is fixed with a substantially vertically extending Swing arm 9 connected with its one end region around a fixed Pivot axis 10 is pivotally mounted, the guide 15 approximately extends radially away from the pivot axis 10.
- a roller 12 freely rotatably mounted with its radially rotating Shell 13 on the radially circumferential contour 14 a cam 11 of a first cam mechanism is in contact.
- the rocker 9 on the cam 11, the rocker 9 is corresponding acted upon by a spring 24.
- the first cam mechanism continues to be essentially horizontal extending horizontal coupling 7, which has one end on the suction coupling 6 near the double suction cup 1 and with its other end in middle area of the rocker 9 is articulated and for the horizontal Movement drive of the double suction device 1 ensures.
- the pivot axis of the articulation of the horizontal coupling 7 on the suction coupling 16 simultaneously forms a tilt axis 8 around which the suction coupling 6 when moving their opposite end of the double suction cup 1 in the Guide 15 can pivot and so a tilting movement of the double suction cup 1 causes.
- a coupling 16 articulated which is substantially vertical extends downwards and on the suction pad 6 facing away End carries a freely rotatably mounted second roller 18.
- This role is 18 with its radially circumferential surface 19 on the radially circumferential Contour 20 of a cam 17 of a second cam mechanism in the system, the second cam 17 next to the first cam 11 is also rotatably arranged on the drive shaft 23 and the Coupling 16 and with it the suction coupling 6 and the double suction 1 in drives essentially vertically movable.
- the coupling 16 is corresponding acted upon by a spring 25.
- roller rocker 22 articulated to the coupling 16
- roller rocker 22 freely about a second fixed pivot axis 21 is pivotally mounted.
- the coupling 16 is also with one end articulated to the suction coupling 6, the coupling 16 extends substantially vertically downward. At its second end the coupling 16 can be moved approximately vertically by a double-armed rocker 29 acted upon, the double-armed rocker 29 by a second fixed pivot axis 21 is freely pivotable. With the free end their one swing arm 30 is the double-arm swing arm 29 am second end of the coupling 16 and articulated via one at the free end of the second swing arm 31 freely rotatably mounted second roller 18 ' the radially circumferential contour 20 of the cam plate 17 of the second Cam gear held by a spring 25 'held in plant.
- the first cams 11 and second cams 17 of the two juxtaposed units of the same structure as in FIG. 1 and Figure 3, are arranged offset by 180 ° to each other. This leads to a movement cycle involving two work cycles of the sheet leading edge separator the double suction cup 1 first with its lower suction surface 26 the top sheet 2 in the area the stack leading edge 4 of a sheet stack 5 is detected and at least largely upright.
- the double suction cup 1 is tilted so that its lower one Suction surface 26 from its position parallel to the surface of the sheet stack 5 pivoted in a higher position in the direction of conveyance 3 at the front than at the rear becomes.
- the suction surface 26 adjusts approximately to the natural extension course the one with the rear area still on the sheet pile 5 hanging bow 2, which makes the bow 2 more secure is held by the double suction cup and not unintentionally by the suction surface 26 releases.
- the double suction device 1 moves over the front area of the sheet stack 5 upwards, so that the double suction cup 1 'is then under the sheet 2 raised by the double suction device 1 over the sheet stack 5 move and can capture another sheet 2 "'.
- the double suction device 1 ' carries out the inputs for the double suction device 1 described lifting movement, while the double suction device 1 the input described movement of the double suction device 1 'is carried out.
