Definitions
- the invention relates to a dispensing device for containers, in particular for bottles for use in container cleaning machines.
- Dispensing devices are known per se in numerous designs and are used in particular in bottle cleaning machines to remove the cleaned bottles from a dispensing area formed on the machine from bottle baskets of this machine and to deposit them on a depositing surface along the contact and sliding surfaces formed by the slide guides, from which the bottles are then pushed onto a conveyor adjacent to the depositing surface by a transfer device.
- a delivery device (DE-OS 27 08 935) is particularly known in this case, in which this transfer device is formed by the sliding guides in that they can be pivoted about a horizontal axis lying above the upper reversal point of the movement of the pick-up fingers of the pick-up fingers, namely synchronously with the movement of the pick-up fingers by a second gear arrangement from a rest or starting position in a push-over position and from this push-over position back to the starting position.
- the pivoting movement of the slide guides is achieved in this known device in that the arrangement formed by the slide guides is attached to the two longitudinal sides of the dispenser on a pivot lever which engages with a cam roller in a control or link curve of a control disk and both control disks are there provided on a rotating drive shaft, the horizontal axis parallel to the pivot axis of the sliding guide gene lies.
- the pick-up fingers are provided in this known delivery device on a common lifting or swivel beam, which is attached at both ends to one end of a coupling formed by a lever, which is hinged at its other end to a crank pin.
- the crank pin the axis of which is parallel to the axis of the drive shaft but is radially offset from it, rotates around the axis of the drive shaft.
- each coupling is connected in its central region to one end of an articulated lever or link which is articulated at its other end to a machine-fixed articulation point.
- a disadvantage of the known dispensing device is, inter alia, that whenever the pick-up fingers or their pick-up persons start the downward stroke after returning to the upper reversal point, the sliding guides must be pivoted back to their starting position, ie the return stroke of the overturning movement must be essentially completed: This means in particular that within a full work cycle, which is determined by a full revolution of the drive shaft and includes a downward stroke and a return stroke of the pick-up fingers, only a relatively small part is available for the overtravel stroke and the return stroke. With larger machine outputs, the bottles are greatly accelerated and moved quickly when pushed over.
- the object of the invention is to provide a delivery device which ensures that the containers are safely pushed over from the depositing surface onto the adjacent conveyor or onto an intermediate plate of this conveyor, even with high machine outputs without the risk of the containers falling over.
- a dispenser is designed according to the characterizing part of claim 1.
- a special feature of the dispensing device is that the slide guides are each formed in two parts and consist of an upper, first section and a lower, second section.
- the second sections have the function of the pushover device and are accordingly movable for the pushover stroke and the return stroke; while the first sections are provided fixed on the machine frame of the dispenser.
- This enables the movement sequence for the pick-up fingers and the lower second sections of the slide guides to be controlled in such a way that the downward stroke for the pick-up fingers or their fetching ends has already been initiated before the second sections of the slide guides have returned to their starting position.
- the latter must in any case be the case when the pick-up fingers or their pick-up ends have reached the transition area between the first and second sections of the sliding guides during the downward stroke.
- the part of the work cycle available for the push-over stroke and return stroke is thus extended by a part of the downward stroke of the pick-up fingers, so that, in particular, a significantly greater time is also required for the push-over stroke Is available and here, even with high machine output, excessively fast movements or high accelerations can be dispensed with.
- the length of the upper, first sections of the sliding guides is equal to or slightly greater than the length of the lower, second sections of these sliding guides, so that in this embodiment the time available for the overtravel and return stroke is almost half Downward stroke extended.
- the second gear arrangement with which the second sections of the slide guides are moved for the overtravel stroke and return stroke, is designed in such a way that, at least during the overrun stroke, the second sections of the slide guides are moved in space, their orientation, i.e. but also maintain their inclination in relation to the settling surface, so that when they are pushed over, the contact of the containers does not change against the contact and sliding surfaces formed in the second sections, and here with a corresponding design of these contact and sliding surfaces also for a largely large area Plant the container when pushed over is taken care of.
- 1 is the dispensing device of a bottle washer that is otherwise not shown in detail.
- this dispensing device 1 which is provided on the bottle dispenser or on a dispensing area 3 of the cleaning machine, the cleaned bottles 2 are essentially in an upright position, i.e. with its bottle axis only slightly inclined with respect to the vertical and with its bottom first set down on a setting surface 4 formed by a sliding plate and then pushed upright by this to a transporter or conveyor 5 adjacent to the setting surface 4, with which the cleaned bottles 2 are transported away and its conveying direction is perpendicular or at an angle to the plane of the drawing in FIGS. 1 and 2.
- the cleaned bottles 2 are fed to the delivery area 3 in that these bottles 2 are each arranged in bottle cells of bottle baskets 6. These are provided on a transport element 7 and are moved with this transport element 7 through the various treatment areas of the bottle washing machine, but also past the delivery area 3, specifically in the direction of arrow A in the illustration selected for FIGS. 1 and 2.
- Each bottle basket 6 forms in the direction perpendicular to the direction of movement A, ie perpendicular to the plane of the drawing in FIGS. 1 and 2, a plurality of bottle cells next to one another for receiving a bottle 2 each, these bottle cells pointing downwards with their open side before reaching the delivery area 3.
- the bottles 2 are in the bottle baskets 6 or whose bottle cells are secured against falling out by a sliding plate 8 on which the bottles 2 slide up with their bottom. With each bottle basket 6, one bottle group is moved to the delivery area 3. The number of bottles of each bottle group standing one behind the other in the direction perpendicular to the plane of the drawing in FIGS. 1 and 2 is equal to the number of bottle cells in each bottle basket 6.
- the dispensing device 1 To lower a group of bottles from the dispensing area 3 onto the depositing surface 4, the dispensing device 1 has channel-like slide guides 9 which are open towards the transport device 5; which each form an arcuate, for the transport device 5 convexly curved contact or sliding surface for the bottles 2 and the number of which is again the number of bottle cells of each bottle basket 6 and thus the number of bottles of the bottle groups to be lowered. Furthermore, the dispensing device 1 has 2 pick-up fingers 10 for lowering the bottles, of which one pick-up finger 10 is assigned to each slide guide 9 and protrudes with a pick-up end 11 from the slide surface 9 of the relevant slide guide 9 facing the transport device 5.
- the slide guides 9 each consist of two plastic guide strips 12, which form a slot 13 for the pick-up fingers 10 between them.
- This embodiment has each slide guide 9 both on its upper section 9 'adjoining the dispensing area 3 and on its lower section 9' adjacent to the placement surface 4.
- the slide guides 9 and their sections 9 'and 9 ⁇ have such a curvature that when lowering (arrow B) with their peripheral surface on the slide guides 9 or guide rails 12 sliding bottles 2 with their bottle axis in the drawing planes of Figures 1 and 2 , ie are arranged in the vertical plane including the lowering stroke B and the transport device A and with their axis with respect to the vertical includes an acute angle opening upwards, ie an angle less than 30 ° .
- a delivery roller or segment shaft 14 which is provided in the transport direction A following the sliding plate 8 at the delivery area 3 and is driven to rotate about its axis running perpendicular to the plane of the drawing in FIGS. 1 and 2, the bottles 2 move out of the delivery area 3 located bottle basket 6 downwards.
- Each bottle 2 stands here with its bottom on the pick-up end 11 of a pick-up finger 10 and rests with its peripheral surface against the sliding surface 9 formed by section 9 'of a sliding guide. With the downward stroke B of the pick-up fingers 10, the bottles 2 are lowered and finally reach the section 9 ⁇ of the sliding guides 9.
- the return stroke B 'of the pick-up fingers 10 takes place from its lowest position (lowest reversal point), in which the pick-up ends 11 are at the level of the setting surface 4 or below this setting surface in the upper lifting position of the pick-up fingers, namely counter to the arrow B, so that after a group of bottles or a row of bottles has been pushed onto the transport device 5, a further group of bottles can already be picked up by the pick-up fingers 10 at the delivery area 3.
- the lifting movements of the pick-up fingers 10 and the sections 9 ⁇ are of course coordinated with one another in such a way that at least when the pick-up fingers 10 have reached the transition region between the sections 9 'and 9hub during the downward stroke B, the sections 9 ⁇ in their in FIG 2 starting position shown have returned. Furthermore, of course, the movement strokes of the pick-up fingers 10 and the sections 9 ⁇ , as well as the rotary movement of the segment shaft 14 and the movement of the bottle baskets 6 are synchronized, which is achieved in the simplest case in that all movements are derived from a single drive motor.
- the two-part design of the slide guides 9 with the fixed sections 9 'and the movable section serving as a pushing device 9 ⁇ thus has the advantage that even with a large pushing stroke C a high output can be achieved for the dispensing device 1, with the lowest possible acceleration forces for the Pick-up fingers 10 and the sections 9 ⁇ and for the pick-up fingers 10 and sections 9 ⁇ carrying elements of the dispensing device 1.
- the pick-up fingers 10 are fastened to a walking beam 15 formed by a hollow box section, which is arranged with its horizontal longitudinal axis perpendicular to the plane of the drawing in FIGS. 1 and 2.
- the lifting beam 15 is fastened at both ends to one end of an angled, plate-like lever 16.
- Each lever 16 is hinged at its other end to the crank pin 17 of a disk 18.
- Each disk 18 is provided on a shaft 19, the horizontal axis of which runs perpendicular to the plane of the drawing in FIGS. 1 and 2. It is understood that the axis of each crank pin 17 is arranged parallel to the axis of the shaft 19 and radially offset from it.
- the shaft 19 is rotatably mounted about its axis on a device frame of the dispenser 1, in the embodiment shown Form on two parallel and spaced vertical machine walls 20, which are arranged in planes perpendicular to the drawing plane of FIG. 3 and thus in planes parallel to the drawing plane of FIGS. 1 and 2. At each end, the shaft 19 protrudes beyond the machine wall 20 there and in each case over that side of this machine wall 20 which (side) points outwards or faces away from the other machine wall 20. At these ends projecting outward beyond the machine walls 20, the shaft 19 carries the disks 18.
- the lifting beam 15 is also guided through corresponding openings in the two machine walls 20 and projects outwards at each end via a machine wall 20, although this on the Walking beams 15 attached, substantially radially projecting from this walking beam, plate-like pick-up fingers 10 are provided on a length of the walking beam 15, which are located between the machine walls 20. Accordingly, the slide guides 9 are arranged between the machine walls 20.
- Each of the two levers 16 of the same design is connected between its two ends via a hinge pin 21 to one end of a lever or link 22, which at its other end by means of a hinge pin 23 on a stationary part of the machine frame, ie on the adjacent machine wall 20 is articulated.
- the axes of the hinge pins 21 and 22 lie parallel to the axis of the shaft 19.
- the shaft 19 or the disk 18 rotates counterclockwise, ie in the direction of the arrow D, lies the axis of the crank pin 17 both in the uppermost stroke position of the pick-up fingers 10 and in the region of the downward stroke B, which (region) corresponds approximately to the end of the sections 9 ', on a line L which represents the axes of the shaft 19 and the Hinge pin 23 cuts, in the uppermost stroke position of the pick-up finger between the shaft 19 and the hinge pin 23 and in the end of the sections 9 'corresponding position of the pick-up finger 10 at the downward stroke B on the side of the shaft 19 facing away from the hinge pin 23 total movement stroke of the pick-up fingers 10 or of the walking beam 15 and the lever 16, the hinge pin 21 is always on the side of the line L facing the walking beam 15.
- the sections 9 ⁇ of the slide guides 9 or the guide strips 12 forming these sections are each fastened to plate-like arms 24 which, like the plate-like pick-up fingers 10, are edged, i.e. with their sides arranged in vertical planes parallel to the drawing plane of FIGS. 1 and 2.
- the arms 24 are each fastened at their other end to a walking beam 25 which extends through openings in the machine walls 20 at both ends.
- the walking beam 25 formed by a hollow box section is connected to one end of a plate-shaped support arm 26 which, like the coupling or lever 16, is edged, i.e. is arranged with its sides in vertical planes parallel to the drawing plane of Figures 1 and 2.
- Each support arm 26 is articulated at its end remote from the walking beam 25 by means of two hinge pins 27 and 28 on the one end of a double-armed lever 29 or a link or lever 30.
- the lever 29 is in its central region by means of a hinge pin 31 on a stationary part of the machine frame of the dispensing device 1, i.e. hinged to the adjacent machine wall 20.
- the lever 30 is articulated on the hinge pin 23 at its other end.
- the axes of the hinge pins 27, 28 and 31 are in turn parallel to the axis of the shaft 19.
- each of the two levers 29 has a cam roller 32 which, from the side, has a closed, kidney-shaped shape Control cam 33 engages, which is designed as a self-contained groove on the side of the adjacent machine wall 20 of each disc 18.
- the axes of the hinge pins 23 and 31 are arranged in a common horizontal plane EH1.
- the axes of the hinge pins 27 and 28 lie in the common horizontal plane EH2, the distances between the hinge pins 27 and 31 or 23 and 28 being the same, so that the Hinged bolts 23, 28, 27 and 31 with the intermediate lengths of the levers 29 and 30 form an articulated parallelogram or a parallelogram guide.
- the control cam 33 and the associated cam roller 32 are provided on both ends of the walking beam 25, ie on both longitudinal sides of the dispensing device 1 formed by the machine walls.
- control cam 33 has two areas diametrically opposite each other with respect to the axis of the shaft 19 with a very different radial distance from the axis of the shaft 19, when the shaft 19 rotates and thus the two disks 18 through the control cams 33 and over the Lever 29 a substantially horizontal stroke movement for the walking beam 15 and thus the lifting movement for the sections 9 southe in the direction of arrows C and C 'achieved by the parallel guide formed by the hinge pins 23, 28, 27 and 31 in the form, that the walking beam 25 and the sections 9 ⁇ are only shifted in their position while maintaining the orientation.
- the planes EH1 and EH2 are in each operating position below a horizontal plane EH3 including the axis of the shaft 19, the plane EH1 being above the plane EH2.
- the hinge pins 23 and 31 are provided on the side of this plane facing away from the walking beam 25, namely the hinge pin 31 with a smaller distance from the plane EV and the hinge pin 23 with a larger horizontal plane Distance from this level EV.
- the upper sections 9 'of the slide guides 9 and these sections forming guide rails 12 are attached to plates 34, which in turn are held on a common cross bar 35 formed by a hollow box section.
- the plates 34 are again arranged upright and lie with their sides in planes parallel to the plane of the drawing in FIGS. 1 and 2.
- the transverse bar 35 lies with its longitudinal extent parallel to the longitudinal extent of the walking beams 15 and 25, but also parallel to the axis of the shaft 19.
- the cross beam 35 is fastened at both ends to a machine wall 20.
- the lifting beam 15 In each operating position of the dispensing device 1, the lifting beam 15 is at a level which lies in the vertical direction between the level of the crossbar 35 above and the lifting beam 25 below, the relatively deep arrangement of the lifting beam 25 at a level below the setting surface 4 and due to the essentially horizontal lifting movement of the walking beam 25 between the latter and the crossbeam 35, a relatively large free space remains for a sufficient pivoting or lifting movement of the walking beam 15.
- the walking beam 25 (and accordingly the arrow F) are provided on the latter Sections 9 ⁇ and (corresponding to the arrow G) of the crossbar 35 and thus the sections 9 'provided on this in the horizontal direction, namely the walking beam 25 at each end relative to the support arm 26 there and the crossbar 35 at each end relative to the Machine walls 20.
- the adjusting device 36 for each end of the crossbar 35 is shown in detail in FIG.
- This adjusting device 36 consists of a threaded spindle 37 which is rotatably mounted on the inside of the relevant machine wall 20, ie on the side facing the other machine wall 20, in each case at both ends about the horizontal axis running parallel to the machine walls 20, by means of bearing elements 38 its external thread engages the threaded spindle 37 in an internal thread of an adjusting block 39 which is located between the bearing elements 38 on the threaded spindle 37 and to which the respective end of the crossbeam 35 is fastened.
- the adjusting block 37 is adjacent to the inner surface of the associated machine wall 20 on one side.
- the mounting of the threaded spindle 37 in the bearing elements 38 allows a certain radial displacement of the threaded spindle 37.
- the hexagon 37 'forms in the adjusting devices 36 in each case the end of the threaded spindles 37 facing the sliding guides 9, so that the respective Hexagon 37 'is easily accessible.
- an adjusting device 44 is provided at each end of this lifting beam, which corresponds in its construction to the adjusting device 36, so that the same reference numerals are used for the elements of the adjusting device 44 as for the elements of the adjusting device 36 are.
- the difference between the adjustment devices 36 and the adjustment devices 44 is only in that the bearing elements 38 are provided in each adjusting device 44 on the side of a support arm 26 which faces the other support arm 26, and that the lifting beam 25 is fastened to the adjusting block 39 with its respective end.
- the lifting beam lies with a large number of sliding guides 9 arranged next to one another 25 in its central area, ie in the middle of the machine with a guide piece 45 fastened there to the underside of the walking beam 25 on a support roller 46, which is freely rotatably mounted on a fixed part of the machine frame of the dispensing device 1 about a horizontal axis running parallel to the axis of the shaft 19.
- This very simple and effective support of the walking beam 25 is possible due to the essentially horizontal movement of this walking beam.
