United States Patent 1 2,861,783; METHOD AND APPARATUS FOR SPINNING BOTTLES Josef Steinle, Augsburg, Germany, assignor to Certus Maschinenbau G. in. b. H., Augsberg, Germany, a corporation of Germany Application August 31, 1955, Serial No. 531,747 Claims priority, application Germany October 12, 1954 26 Claims. (Cl. 25954) This invention concerns a method and apparatus for spinning bottles by turning them over from top to bottom by means of a carrier which rotates about a horizontal axis while the bottle is slid along and guided at the bottom and top by means of a screw thread guiding arrangement.
In the case of all known constructions of this kind, the turning of the bottle over from top to bottom takes place about an axis of rotation lying outside the bottle, so that the bottle stands off radially from this axis of rotation. According to the present invention, the turning of the bottle from top to bottom takes place as a screw motion of the bottle by rotation about an axis of rotation lying intermediate the ends of the bottle. It is clear that, for the most part, the effect desired for the mixing of the contents of the bottle is exactly the same, but that the space required for this purpose and accordingly also the technical expenditure for a machine for carrying into practice the new method can be reduced to about a quarter. The power requirement is also, of course, consequently reduced; the cost of installation and operation are considerably cheapened. The advantages obtainable with the invention are thus very significant.
The method can be carried out in various manners; likewise numerous forms for a machine for carrying out the method are possible. In the preferred form of the invention the turning from top to bottom takes place about an axis of rotation lying on the line of bisection of the length of the bottle.
In one embodiment of bottle spinning machine constructed in accordance with the invention, the screw thread guiding arrangements for the top and bottom of the bottle run beside one another on the inner wall of a cylindrical housing. The rotating carrier or carriers is or are fastened each on an arm or annular disc of only narrow area interrupting the stationary screw thread guiding arrangement, which arm or disc is mounted on a rotating ring whose interior diameter allows the length of the bottle to pass through. Such a narrow break of the stationary guiding arrangement does not interrupt the ordered passage of the bottle; however, as a safeguard,
an inwardly-lying bridge guiding member fastened on the main screw thread guide may be provided at the break, and may have a restricted lateral projection under which may pass a rotating angle bracket carried inside the main screw thread guiding arrangement by the interrupted narrow part of the rotating ring, the latter rotating outside said bridge guide member.
In this embodiment, two diametrically opposed carrier jaws are suitably provided, between which the bottles are carried on both sides. The rotating ring may be formed as a belt pulley, preferably a V-belt pulley. It has as small a wall thickness as possible, so that a housing for the screw thread guiding arrangement may be situated only a little above the conveyor belt and the bottles only need to be raised slightly on entering the machine or lowered slightly on leaving. I
According to another embodiment of the invention, the rotating carriers revolve outside the screw thread guiding arrangement. In this case the rotary drive requires no interruption of the screw thread guiding arrangement. It is to be regarded as a further advantage of this embodiment that the rotating carriers may possess a collar sup- ICE porting the bottom of the bottle during the lower half of the top to bottom rotation. The necessity for the construction of a supporting housing member is thus reduced to a minimum; the whole machine contains in addition only a supporting framework and may be completely inspected, since transparent material can be used as a cover. In case the fore part of the bottle provides an insufficient supporting base on the stationary screw thread guide during the upper half of the spinning motion, perhaps on account of an over-slender bottle neck, such as may occasionally happen, a supporting collar for the top of the bottle and lying opposite to the supporting collar for the bottom of the bottle may be rotated therewith.
The supporting collars of the rotating carriers may conveniently extend only over the axial distance between stationary entrance and exit guide members for the bottom of the bottle, which members approach from the plane of the conveyor belt or a little above or below it respectively, to the imaginary axis of rotation of the carrier, advantageously curving through substantially According to a further feature of the invention a spiral segment is arranged between the two ingoing edges of the rotating carriers outside their inlet aperture, which acts as a keep-off rail for the entrance of the bottle, and with which any undesirable locking at the bottle inlet is avoided, independently of the kind of bottle which is put in, and without special control members being required for this purpose. To this extent also the invention ofiers a considerable simplification and cheapening as compared with known devices.
The stationary screw thread guide, according to yet another feature of the invention, is formed of two spirals, supported outside the area of rotation of the carriers, and each having the same pitch, but of a spacing or interval so displaced relative to the centre of the pitch that a space corresponding to the thickness of the fore part of the bottle is opposite to a space corresponding to the thickness of the foot of the bottle. It has been found surprisingly that with this extremely simple screw thread guiding arrangement a satisfactory guiding of the bottle on an axially progressing path while the bottle is being turned over from top to bottom is automatically obtained.
According to a still further feature of the invention, both the spirals forming the screw thread guiding arrangement consist each of a pair of spirals, of which in each case the one spiral is of a larger diameter than the other spiral, and are axially adjustable in stationary supports. It is .thus possible to alter the desired intervals corresponding to the thicknesses of the foot and fore part of the bottle and to adjust it to the most varied sizes of bottles. While this is possible, namely, by means of a suitable axial displacement of the one spiral in the one direction and of the other spiral in the opposite direction, the inevitable dependence of an increase in spacing on the one hand on a decrease in spacing on the other hand in the case of only two spirals is avoided. The stationary ingoing and outgoing guide members may conveniently be attached to the end of one spiral only; the end of the other spiral can then be displaced relative to the ingoing and outgoing guide plates.
The carrier may also conveniently be a two-part construction and the space between its two jaws made adjustable, so that a good fitting and reliable operation are also ensured by means of the accommodation of this space to the thickness of the foot of the bottle.
For an increase in the speed of operation, another feature of the invention is preferred, in which the supporting collars for the top of the bottle lie opposite to the rotating carriers provided with the supporting collars for the bottom of the bottle; the two diametrically opposed supporting collars are fixed so that they are adjustable in 3 height so that different lengths of bottle can also be taken into account.
The new bottle spinning machine is thus largely adjustable to any shape and length of bottle. Naturally, the possibility of variable fitting cannot be carried to an indefinite extent without the guiding function sufiering thereby. Nevertheless, the basic unit, which includes the supporting framework and the rotating ring together with its driving mechanism, can be designed for bottles of all lengths, so that a single basic unit can be used, into which, for bottles of widely variable sizes, different guiding units, consisting of rotating carriers and a stationary screw thread guide together with the ingoing and outgoing guiding members, can be inserted. In order with such a construction, to enable even the shortest bottles normally used easily to be received with their imaginary axes of rotation coinciding with the imaginary spinning axis of the machine, the base of the latter is adapted to be lowered below the plane of the conveyor belt, and the belt is interrupted in the region where the bottles are turned.
A particular further advantage of this feature of the invention is that, because of the fact that the carrier revolves outside the screw thread guide it is possible for three or more carriers to be distributed around the circumference, whereby the pitch of the screw thread guide must accordingly be kept such that a bottle following a preceding one may follow the first after the latter has turned through an angle of revolution of 120 or 90. The plurality of carriers than corresponds to a corresponding plurality of supporting collars for the top, inasmuch as there is any value attached thereto. For the same number of revolutions, the output of the bottle spinning machine can in this way be multiplied.
The invention will be described further, by way of example, with reference to the accompanying drawing in which:

In the bottle-spinning machine illustrated in Figs. l-7, an ingoing guide member or respectively an outgoing guide member 2 of a cylindrical housing 3 is attached to extend laterally of a conveyor belt 1 at the inlet side and correspondingly also at the outlet side, either at the same height in each case, or the ingoing guide member may be a little below the outgoing member. Coincident with the longitudinal axis of the housing 3 there lies the imaginary axis of rotation of two carriers 4, which are situated diametrically opposite to each other, and which leave between them a longitudinal gap of the same width from top to bottom, through which a bottle a can move irrespective of whether it is in the position shown in the drawings or in a position displaced by 180 with respect thereto. At their ingoing end the carriers 4 are provided with projections 5 curved in the direction of rotation, which first function actively as carriers by seizing the bottle, and relative to which the set back contour of the edge 6 effects a delaying of the forward motion of the bottle, so that the acceleration of the bottle is moderated. The bottle begins its spinning movement with its base in a screw thread guiding member 7 and with its top in a screw thread guiding member 8 running beside the member 7. The axis of rotation of the bottle thus passes through the line bisccting its length. In this way the bottle travels forward with repeated turning over from top to bottom, through the two longitudinal slots which the two carriers 4 leave free between them.
The carriers 4 are held and rotated by means of a V-belt pulley 9, which is driven via a V-belt it) by the motor 11, and which is mounted between two bearing discs 12 connected with each other by distance pieces 13 and firmly secured to the two parts of the cylindrical housing 3. The V-belt pulley 9 carries a narrow annular disc 14, which interrupts the path of the screw thread guide members at 15. An angle bracket or segment formed from two pieces 16 and 17 connects the annular disc 14 with the carrier 4. The piece 16 is so dimensioned and arranged that it can rotate inside the paths of the screw thread guiding arrangement and thereby travels externally under a bridging guide member 18, which is attached at a suitable interval b at 19 to the interrupted ends of the main screw thread guiding arrangement. The length 0 of the piece 16 for this purpose is made somewhat larger than the lateral projection c of the bridging guide member 13 extending across the break 15. If, however, as is entirely possible, allowance is made for the break 15 and a bridging guide member 18 is not used, then the angle pieces 16, 17 are not necessary; the annular discs 14 can extend directly up to the carriers 4; since they rotate with them, they do not interfere at all with the passage of the bottles.
The belt pulley 9 is thin-walled, so that as can be seen in particular in Fig. l, the cylindrical housing 3 fits closely above the conveyor belt 11. The pulley may alternatigely be formed as a gear wheel, worm gear or the l' e.
Since the bottle only has to be supported during the lower half of its top to bottom rotation, the cylindrical housing 3 need not be carried completely round, or it may have a transparent cover on the upper half. If it is not desirable for the bottle to rest on its stopper, supports 21 for the shoulders of the bottle may be provided on the rotating carriers 4 or may be arranged in a fixed position, as indicated in Figs. 6 and 7, which in the latter case are effective at least in the lower half of the top of bottom rotation; if the supports 2:) are attached to the carriers 4, the latter can only take the bottles along in one position relative to said carriers.
In the case of the embodiments shown in Pig. 8 et seq., an ingoing guide member 2 is also attached to extend laterally of the bottle conveyor belt 1 travelling in the direction of the arrow A, at the inlet side a little above the plane of the belt, which member approaches the imaginary axis of rotation of the carrier in a curved sect10n of about and therewith lifts the battle a slightly out of the plane of the belt ll. On the opposite side, at the outlet end, is a corresponding outgoing guide member, not visible in Fig. 8, but readily seen in Fig. 11.
A sprocket wheel 41 is driven by an electric motor 11 by way of a transmission gear including a slipping clutch 42 tensioned by a spring 43, and from it is driven via a chain 10 a sprocket wheel 40 formed on the outer surface of a ring 9. On the inner surface of the ring 9 are provided flange attachments 44 on which, inter alla, are attached the carriers 4 of Fig. 8.
At their inlet end, the carriers 4 possess projections S curved in the direction of rotation shown by the arrow D, which on seizing the bottle first actively function as carriers and relative to which the set back contour of the edge 6 efiect's a delay to the forward motion of the bottle, so that the acceleration of the bottle is moderated. The
7 bottle begins its spinning movement with its base on the ingoing guide member 2, with its lower part in an approximately dimensioned broad space 7 between two spirals 30 and 31, and with its neck in the correspondingly dimensioned narrow space 8 between the two spirals 130 and 131. As the ingoing guide plate 2 approximates towards its upper end more and more to the imaginary axis of rotation, the bottle is inserted so far into the windings of the spiral that it is supported during the upper part of its top to bottom rotation with its fore part already on the spirals at their narrow interval 8. The two additional attachments 30 and 31' serve only for an easier insertion of the bottle. Otherwise the two spirals only efiect the screw thread guiding action on the fore part and lower part of the bottle. In the position marked the bottle a has accomplished three-quarters of a turn. At the bottom the bottle is supported during the lower part of its spinning motion by means of the supporting collars 4" of the carriers 4'. As may be seen from Fig. 8, the two jaws of the carriers 4' are separated from each other and each of itself is equipped with a supporting collar. They may be removably screwed on to the flange attachments 44, as well as over the longitudinal slots in such a way that the width of the space between the two jaws of the carriers is adjustable.
As may be seen, he carrier rotates round the stationary screw thread guiding arrangement, which is attached to the supporting framework 0 by means of the pillars 32, a two-part housing cover 12 for the rotating ring 9, which also carries the motor 11, also being fixedly secured to the framework 0.
The supporting collars 4" do not extend as far as the region of the ingoing and outgoing guide members 2, but only intermediate them. A similar supporting collar 45 (Fig. for the top of the bottle can be disposed diametrically opposite to them on the ring 9, if this is desired for the purpose of increasing the speed of rotation.
Fig. 9 illustrates a construction of the fixed screw' thread guide member including a pair each of spirals 30, 130 and 31, 131, the spirals 3t), 31 being of a larger diameter than the spirals 130, 131. Consequently one pair of spirals can be axially displaced relatively to the other pair in longitudinal slots 33 in the fixed pillar supports 32,
in order for example, to obtain a larger space 7 for the 7 lower part of the bottle for thicker bottles without this being of necessity combined with a reduction of the space 8 for the fore part of the bottle, as would be the case with the single spirals according to Fig. 8; on the contrary, by means of the opposite displacement of the other spirals a larger space 8 can also be obtained for the fore part of the bottle.
Figs. 10 to 12 show a bottle spinning machine constructed with double spirals. From these figures it may further be seen that between the two inlet edges of the rotating carriers 4' a spiral segment 46 may be provided outside their inlet opening which serves as a keep-off rail for the purpose of eifectively maintaining the inlet for the bottles outside the inlet opening. It may be additionally supported by means of rods 46' on the flanges 44 of the rotating ring 9.
It may further be seen from Figs. 11 and 12 that lateral guiding arms 2' of the inlet and outlet plates 2, which 'are omitted altogether in Fig. 10, are formed, in contrast to the simplified construction according to Fig. 8, as attachments of the spirals 30, 31. Connecting arms 102 form the bridge for this purpose (Fig. 12). Only one of them is welded to the plate 2, at 102", so that the axial dis,- placement remains possible.
Fig. 12 allows the longitudinal slots 50 and 51 for fastening the carriers 4' to the flanges 44 of the rotating ring 9 to be seen, s0 that the carriers can be adjusted in height and with reference to the lateral space for bottles of different thicknesses and lengths.
Fig 13 illustrates the possibility of allowing thebottles to follow one another after turning 120, inasmuch as games i the pitch of the screw thread guide member is suitably constructed so that succeeding bottles are at a sufficient distance from one another in theaxial direction. It is also possible to provide supports 45 for the tops of very narrow bottles, which can also be adjusted in height at longitudinal slots 145 on the flanges 44 of the rotating ring 9. In this case three pairs of carriers 4 are provided. Four pairs of carriers can also be provided if no top supports are provided; the bottles then follow one another after a turn of with a corresponding pitch of the screw thread.
Finally, Fig. 14 illustrates diagrammatically the possibility of interrupting the bottle conveyor belt 1 in order to be able to lower the rotating ring 9 together with its basic unit below the plane of the belt, as the left-hand half of the figure indicates. It is possible by this means to be able to use the same basic unit with bottles of very different lengths (compare that on the left-hand side and that on the right-hand side of the figure), and nevertheless to bring the centre of the bottle to the centre of the spiral. In such a case, the fixed screw thread guide member is made available in two different sizes of diameter, and is adapted to be interchanged in the basic unit. If need be, a third screw thread spiral of still smaller diameter, which can be inserted'for very small-sized bottles by means of corresponding axial displacement, can also be provided at the same time.
It is thus apparent that this exceedingly small and simple bottle spinning machine can be assembled in numerous variations for bottles of all normally utilised thicknesses and lengths. 1
