Control and separation device
of moving products, such as bottles or the like.,
in a continuously operating system

The invention relates to a device for the automatic control and separation of moving products, such as
Bottles or the like, in a continuously operating system
and in particular to a device for checking the filling level
and the closure of bottles that are filled and corked in such a continuously operating system, so-
! as for the removal of poorly filled and poorly

f cork bottles.

The continuously operating processing plants, ie the
Processing plants in which products are continuously and with
constant speed, and at which

the work processes also affect the moving products \

are due to the increased production \

speed for filling and corking bottles every- j

common in action. Because of this increased production speed |

The control to be carried out during operation, such as |

you when weeding out defective products, a serious 1

Problem. Κ

In the known systems for filling and corking bottles with a relatively low production speed, the filling level and the proper corking are checked visually, so the operating staff must be careful and manually remove poorly corked bottles from the machine, which is continuous with the use of modern working systems has become practically impossible, for example when the production speed exceeds ten bottles per second.
(.)

The invention is therefore based on the object of a device to make available who control the products and allows the removal of defective products from a continuously operating plant at a very high rate Production speed works, with the control being done safely and precisely and without using complicated and more expensive devices are to be made possible.

This task is solved by adding the in the license plate of claim 1 specified features to those of the preamble.

The partial axial section shown in Fig. 1 shows a control housing 1. It is arranged on a base 2 on which a support 3 is fixed, which contains a vertical central bore 4 in which a vertical shaft 5 with the longitudinal axis 0-0 is wedged. A cam drum B is wedged tight above the support 3. The rotating part of the control housing is mounted between the support 3 and the cam drum 6. This rotating part of the control housing has a hollow shaft 9, two disks 10 and 11 and a crown 12. The hollow shaft can be rotated centered around the longitudinal axis 0-0 via bearings 7 and B. This also applies to the plates 10 and 11 fixed on the hollow shaft 9. The crown 12 is bolted to the disk 11 via carrier 13. These rotatable parts, consisting of the hollow shaft 9, the disks 10 and 11 and the crown 12, are around the Longitudinal axis 0-0 by means of an inner ring gear 14 which is positively connected to the disk 10, a gear 15 and a shaft 1B _{3 can be driven} by a motor (not shown), mounted in the base 12.

The disc 10 has support 17 which is uniform over the outer periphery of the control housing 1 are distributed, in which the bottles to be controlled 18 are arranged, as on the right part of Fig. 1 can be seen. In this position, a bottle 1B is held in the carrier 17 by a pressure piece 19, Wblches are pressed against the bottle wall by a leaf spring 20 will.

Sliding piece 24 seated on it, a bottle can be picked up to continue from the lower position in which the bottle is located 18 is located in the right part of Fig. 1, in an upper layer, shown on the left side of Fig. 1. Each .Gleitstück 24 is connected via a boom 25 to a linkage 2B, guided in the disks 10 and 11 and in one Linkage bearing 27, which is connected to disk 11 by a support 28. A body 29 is with each linkage 26 is connected and carries a control roller 3D, which moves in a way that will be explained later is described, in a groove 31 of the cam drum 6. The Linkage 26 is provided with a ramp 32 which actuates the rocker arm 21 via a roller 33, as described later Wise. A control device 35 is visible on the upper part of FIG. 1, connected to the base 2 via a support 34. On the one hand, it consists of a control device for the presence of its bottle closure, in particular consisting of a control shaft 36 with a head 37 and a Proximity detector 38, and on the other hand, consisting in particular of a control device for the filling height of the bottle from an optical emitter 39 and 40, symbolically by arrows shown, and the optical receivers 41 and 42. The numeral 43 denotes an electronics housing with the reading circuits of the signals delivered by a proximity detector 38 and the receivers 41,42.

The function of the mechanism is described below. Bottles 18, filled and closed, which come from the filling and closure system, are automatically placed in the moving carriers 17 in the position shown in the right-hand part of FIG. 1. In the known manner, this can be done adjusting the bottles 18 in

During this rotation of the control housing 1, each roller 30 is displaced in the groove 31 of the stationary cam drum 6 The action of each body 29 in its upper position with entrainment of the linkage 26, the boom 25 and the slider '24 associated with him. By means of the plunger 22 and the spring 23, the slide 24 lifts and guides each bottle 1B into the upper position, as shown on the left-hand side of FIG. To facilitate the transport of the bottles 16 from f the carrier 17 controls the ramp 32 of the linkage 26 via the roller 33, the two-armed rocker arm 21 and thus the leaf spring 20, so that the pressure piece is released from the corresponding bottle.

In the upper position, which is shown on the left side of FIG. 1, the upper end of the bottle 18 is brought under the action of the tension spring 23 via the elastic stop on r, a lower stop surface 44 of the crown 12, which the control shaft 36 raises.

If a bottle is properly closed, the control shaft 36 moves it up into the position on the left Side of Fig. 1 is shown, i. H. if the bottle is not closed by a cap, the remains Control shaft 36 in its lower position, which is shown on the right side of FIG. 1, with its head 37 on the upper side of the crown 12 seated.

the control shaft 36 in the upper position (bottle with Shutter), then his head 37 moves very close under the proximity detector 313, causing a pulse to the electrical Causes the reading circuit, which is located in the electronics housing 43.

In the manner as described in detail below, these circuits control the lowering of slide 24 and plunger 22, this causes bottles to be carried along

16 in the carriers 17, whereby by lifting the pressure piece their exit is facilitated, the triggering takes place through the ramp 32. The in this way on their place in the carrier

17 remaining bottle 18 is through the chain from the carrier to another control housing of the continuously operating System, e.g. a control housing for labeling.

lower position with his head too far from the detector to cause excitation and no pulse is applied routed to the evaluation circuitry.

The control operations and the eventual rejection relating to the closure of the bottles will now be described. the Control and possibly the sorting out in relation to the filling of the bottles take place in an analogous manner simultaneously checking the bottle cap. Then every bottle that was put in its upper tier goes (left part of Fig. 1) between the optical emitter 39 and the optical Receiver 41 through which the lower filling level is determined, and also between the optical emitter 40

and the optical receiver 41, whereby the upper filling level is determined, the height of the bottle contents is recorded in the following way: If a bottle is correctly filled, the liquid level lies between the lower filling level corresponding to a horizontal light beam that goes from the emitter 3D to the receiver 41 and the upper filling level corresponds to a horizontal light beam that runs from emitter 40 to receiver 42. Hence the light beam 39-41 at least partially darkened, the light beam 40-42 is unchanged.

If too much has been added, the liquid level will exceed the plane of the upper bundle 40-41, then the two bundles 39-41 and 40-42 are at least partially darkened.

If too little liquid was poured in, it is Liquid level below the lower bundle 39-41, then neither bundle is darkened. The corresponding Luminescent flux, received by the receivers 41 and 42, is im Electronics housing 43 in electrical voltage proportional converted to the intensities of this flux and becomes adjustable. At the output this voltage has been set so that the voltage signal in the presence of an empty bottle is excited by the bundles 40-42.

These two voltage signals are in the electronics housing 43, which are suspected in the event of a positive exit, connected to an additional circuit with one another after the Voltage signal corresponding to the lower bundle 39-41 was converted into a negative value. In this state it becomes Exit signal of the additional circuit can be as follows:

Near zero if a bottle is not filled correctly, i.e. if the filling level is below the bundles 39-40 or below the Bundles 40-42 lies.

A clearly positive exit signal from the auxiliary circuit is transformed into an electrical impulse, which is reflected in the evaluation circles located, mounted in the housing 43 and this brings the same consequences as the given impulse, since one him through the proximity detector for exercising control of the bottle cap sees much higher, d. H. a bottle 18 remains in the carrier 17 and then becomes another control housing spent.

On the other hand, there is an exit signal near zero of the additional circuit due to the absence of an impulse, then becomes the removal of the bottle 18, when it is still in its upper position, is effected in the same way as in the previous one Case where the absence of the bottle cap stuck.; is caused by the lack of a pulse from the proximity detector, which results in the bottle being removed from its top layer Has.

3a to 3d are partial sections in the area of the linkage 26. A part of the cam drum 6, the rollers, can be seen there 3D and the body 29. A slider 50 is located in a bore 51 of the body 29 in which, without being rotated, can slide. A spiral spring or the like 52 presses the slider 50 against the cam drum 6. At its the cam drum 6, the slider 50 carries the freely rotatable roller 30, freely rotatably mounted on a bearing journal 55. A counter roller 54 extends perpendicular to the bearing journal of the roller 30, which is also connected to said end of the Slider 50. A flat piece 56, pivotable about a horizontal axis 57 and by a spiral spring or the like 58 constantly kept pivoted upwards, can be pivoted back down by an electro-magnet 59 r.3ch if a coil 60 this electro-magnet 59 has current flowing through it. The flat piece 56 carries a pawl 61 on its upper side, which - Under the action of the spiral spring 58, when the electro-magnet is not excited - into the recesses 62 and 63 of the slider 50 can intervene.

This device described in FIGS. 3a to 3d operates as follows:

The starting point is FIG. 3d, in which the sliding block 50 engages in the bore 51 and compresses the spiral spring 52, It is held in this position by the pawl 61, which engages in recesses 62. The counter roller 54 is then not in engagement with the cam drum 6. In the position shown in Fig. 3d there is a bottle in the upper position, has not yet reached the control device 35 and the proximity detector 38 (FIGS. 1 and 2). The bottle that resulted of the revolution of the control housing 1 approaches the control device 35 and the proximity detector 38, shifts due to a slight Increase in the radius of the cam drum 6 slightly on the left, because the counter roller 54 now moves the slide shoe 50 (FIG. 3a). This releases the pawl 61 from the left one

vertical surface of the recess 62. and can now easily solve from the recess 62, whereupon the flat piece 56 by the electro-magnet 59 is pulled down. One also sees on Fig. 3a that the slight increase in the radius of the cam drum 6 is accompanied by an increase in the depth of the groove 31 of this cam drum 6 in which the roller 30 engages.

Due to the constant rotation of the control housing 1, the bottle is then in front of the control device 35 and the proximity detector 3B, which act simultaneously to control the bottle closure and its filling. When closure and filling are correct, electrical pulses run simultaneously through the proximity detector 38 and the auxiliary circuit of the signals from the Receivers 41 and 42 opens accordingly. Two relays 61 and 62 arranged in the housing 43 are mounted parallel to one another (Fig. 3b) in the circuit of the coil 60 of the electric magnet slot 59, and that has the interruption of the supply current from the coil 60 during the common duration of these two pulses Consequence.

By means of a switch, not shown, controlled by the revolving control housing 1, the supply circuit for Coil 60 energized during the time interval in which the aforementioned common impulses persist inside. Since relays 61A and 62A are open, no current flows through the coil 60. If, on the other hand, the existing bottle is incorrectly closed or incorrectly filled, or both, then at least one of the relays 61A and 62A remains closed and the pulse 60 is energized for a short time interval set.

The electro-magnet 59 is then excited and the flat piece 56 is pulled down, causing the pawl 61 from the Recess 62 is pulled out and thus released from the slide shoe 50.

Under the action of the spiral spring 52, the sliding shoe 50 then printed to the right and thus onto the roller 30. The power supply to the coil 60 is interrupted, the excitation dgs electro-magnet 59 stops and the flat piece 59 becomes swings in the upward direction by the spiral spring 5B. The The control housing 1 continues to rotate, the radius of the upper part of the cam drum B decreases and the slider 5G is displaced consequently to the right until the pawl 61 engages in the recess 63 of the slider 50 and blocks it. The radius of the cam drum 6 is reduced somewhat in such a way that to break the contact between it and the counter roller 54 and ends in the position shown in Fig. 3b.

If one now looks at the development of the grooves in the cam drum 6, which is shown in a view in Fig. 4, it can then be seen that the groove 31 divides between the points A and B, namely in an upper groove 311 and a lower groove 312. The upper groove 311 and also two small sections of the groove 31, placed on the outside of the section AB correspond to the maximum depth D shown in Figures 3a, 3b and 3c is, while the rest of the groove 31, as well as the lower groove 312 represent the minimum depth d_, as noted in Fig. 3d is.

In the event of a fault in the bottle cap and / or in the filling the roller 30 reaches the position which is shown in FIG. 3b C depth D). It is then a little higher above the Point A in the sense of a movement in the direction of arrow G [Fig. $ 4. As soon as it gets to point A, it moves in of the upper groove 311, which causes the bottle in the upper Position is held to allow removal by the rejection drum 48.

The groove 311 now meets again with the groove 31 at point B, whereby the punch 22 is brought into a lower position.

At this moment the radius of the cam drum increases again, whereby the slide shoe 5D over the counter roller 54 is shifted to the left, which causes the pawl 61 from the recess 63 of the slide shoe in the Recess 62 engages [Fig. 3c). The radius of the cam drum 6 is again reduced somewhat, which corresponds to the position according to FIG. 3d.

On the other hand, if the bottle is properly closed and properly filled, then relays 61A and 62B are on during the short time interval opened, the electro-magnet 59 is not excited and the slide shoe 50 remains in the pawl 61 through the Blocked position, as shown in Fig. 3a. The roller 30 then runs at point A into the lower groove 312 CFig. 4), connects then again with the groove 31 at B. So the bottle, which is still in the carrier, is guided into its lower position.

The control of the bottles and their release became the foregoing described according to two criteria! Closing and filling. It is clear, without departing from the scope of the invention, that control and discarding could also be done according to a different number of criteria, with being selected could, in addition to capping and filling, according to other criteria that are applicable to products other than bottles.

Generally speaking, the invention is not limited to the exemplary embodiment explained. So starting from this, you can designs and other types of embodiment can also be selected without departing from the scope of the invention.
