Description

[0001] The invention relates to an automatic bottle filler for refilling bottles using liquid detergent, comprising a bottle washing and cleaning unit, a filling device and a label applicator, all controlled by a central control unit, and further comprising a customer operable control unit.

[0002] One important part of protecting the environment is to reduce the amount of packaging material that is normally thrown away after a single use. This is particularly true for bottles that are designed for reuse. Re-use is preferable to recycling of excess materials, which in all cases involves energy consumption and low environmental impact. These findings are particularly true for plastic bottles.

[0003] In the case of re-use, it must also be ensured that there are strict requirements for the correct labelling of the products purchased, in particular the indication of the manufacturer, the date of manufacture and guarantee and the composition of the contents, and that these conditions cannot easily be guaranteed in the case of re-use.

[0004] The Hungarian patent 231,312 discloses a bottle filler which takes adequate care of refilling bottles, but at the same time its design is space-consuming, the bottle is moved between the process stations for refilling, and therefore it has a separate bottle receiving and dispensing compartment. The equipment receives bottles without caps, i.e. old caps that are still in perfect condition have to be unscrewed from the used bottle and discarded by the owner, as the equipment always provides the bottle with a new cap. Not only represents this a waste of material, but in many cases the cap is so tightly clamped to the bottle that the average user does not have the strength to remove it, or, if forcefully unscrewed, both the cap and the bottle get damaged, making refilling impossible.

[0005] That bottle filler also has a problem with proper labelling because the space available in the equipment is not sufficient to print in sufficient quality.

[0006] Despite the drawbacks outlined here, that solution has been a major step forward from the state of the art at the time, as earlier solutions could not even satisfy the conditions for reuse to this extent.

[0007] The object of the invention is to create an automatic bottle filler for refilling bottles of liquid detergent, which eliminates the disadvantages of the known machine, i.e. it can refill bottles with caps, it requires less space, i.e. it does not have separate loading and unloading compartments, and the label it applies satisfies all the requirements in terms of quality and accuracy.

[0008] The task was solved by creating a bottle filler of the design specified in the attached claims.

[0009] The automatic bottle filler according to the invention is described in more detail below, with reference to the drawing. The drawing shows:

[0010] In Figures 1 and 2 the side and front cross-sectional views of the automatic bottle filler 10 according to the invention are shown, in which only the structural units necessary to perform and illustrate the main functions thereof are shown, because showing the complete design would unnecessarily complicate understanding. In terms of its intended use and main functions, the automatic bottle filler 10 is very similar to the machine described in HU 231312. The difference lies in that in the cited patent the bottle was placed in the bottle receiving compartment of that automatic filling machine, and was carried by a conveyer line in lateral direction to the adjacent process stations, and finally, in the last operation step, the bottle was transferred to a bottle discharge compartment remote from the receiving compartment, from where it could be removed by the customer. In the present solution, the rectangular bottle 11 remains in place until the filling process is completed. A further difference is that in the solution referred to, the cap had to be removed from the bottle to be filled beforehand, and a new cap was always applied to the bottle at the time of filling. The solution according to the invention ensures that the cap is removed, cleaned and replaced after filling. This makes a significant difference, because suitable caps are not cheap, are not usually damaged during use and can be reused. Their unnecessary disposal and replacement would result in environmental pollution and waste.

[0011] Figure 2 shows a support plate 12 behind the receiving compartment, which is not shown, and behind the receiving compartment a small scale 13 is arranged on the support plate 12, which latter provides a receiving and support surface for the bottle 11. The design of the bottle 11 is preferably identical to the one forming the subject of the Community design 006189031-001, and the internal volume of the bottle 11 is preferably 2 litres, to be filled with liquid household detergent or a similar cleaning liquid.

[0012] In the following, the structural elements that implement the various technological steps of the bottle filling machines 10 and their ways of operation are described.

[0013] In Figure 2, above the flask 11, two structural units are schematically sketched, which can be moved both laterally, i.e. left-right in Figure 2 and up-down in Figure 2, by a moving mechanism not shown in the drawing, and their movement is controlled by a central control unit 90 shown in Figure 10.

[0014] After inserting the bottle 11 and identifying the customer, the first technological task is to remove the cap from the bottle 11. The cap remover (and applicator) 20 used for this purpose is illustrated in its different height positions in Figures 3a and 3b, and in its lowered operating position in a side view in Figure 3c. The cap remover 20 has a fixed height stator 21 and a moving part 28 vertically guided therein. The stator 21 has two spaced apart cylindrical guide columns 24, 25 mounted between two spaced apart support plates 22, 23 and a central guide cylinder 26, which are responsible for guiding the moving part 28 in vertical direction in a stable way.

[0015] In the moving part 28 there are two supporting columns 29, 30 at its ends, which are guided for vertical displacement in the guide columns 24, 25, and a horizontal supporting plate 31 connected to the top of these, a central cylindrical guide bushing 32 mounted on this, and a rod 33 journalled in the bushing 32 and projecting in downward direction out of the lower end thereof. The top of the rod 33 guided inside the guide bushing 32 protrudes above the guide bushing 32, and the support plate 22 is rigidly connected to a belt pulley 34. In the side view of Figure 3c, it can be seen that a motor 35 is laterally attached to the support plate 31 and its rotor terminates at the top in a driving belt pulley 36. The pulleys 34 and 36 are connected by a belt 37, whereby the rotation of the motor 35 directly drives the rod 33. The lower end of the rod 37 is connected by means of a vertically guided spring connection 38 to a vacuum controlled bushing 39 that has a task of squeezing the cap and has a downwardly open inner chamber.

[0016] The operation of the cap remover 20 is as follows. After the insertion of the bottle 11, from the initial position of the cap remover 20 as shown in figure 3a, it is moved in the direction of the bottle 11 by a lateral movement not shown in the drawing, so that the axis of the rod 33 will arrive in the extension of the axis of the bottle 11. Then, by the pressure of the hydraulic fluid in the guide cylinder 26 and/or in the guide rods 24, 25, the moving part 28 moves downward in vertical direction until it arrives in the position shown in Figures 3b and 3c, where the bushing 39 is clamped by a pressure on the top of the cap 40a of the bottle 11, sketched in Figure 3c. The pressure is provided by the spring connection 38. The central control unit 90 then establishes a vacuum inside the bushing 39 to a given extent, thereby creating a tight contact between the bushing 39 and the cap 40a. The motor 35 is of a special design and has a high starting torque, the amount of which can be varied in a controlled manner between a minimum and a maximum value. For the removal of the cap, the rotational torque is varied in a very dense and pronounced, jerky manner in the direction opposite to the direction of the cap thread, and this has the effect of releasing the cap even if it has been twisted by the maximum amount to the top of the bottle 11. When the control senses that there is no longer any perceptible resistance of the cap 40, the motor 35 will unscrew the cap from the bottle 11 after a given number of complete turns, and the lifting is provided by the previously tightened spring connection 38. This completes the unscrewing operation of the cap 40 and the cap remover 20 moves away from the line of the bottle 11 while retaining the cap 40.

[0017] Note that until the filling of bottle 11 is completed, there is sufficient time to treat the inside of cap 40 with an ozone disinfectant, and then, after the filling the bottle 11 is completed, the cap remover 20 moves back to the position above bottle 11 and the winding of cap 40 is done by rotating the motor 35 in the opposite direction, and here the control is dimensioned so that the winding is completed after a prescribed torque is reached. When the vacuum is released, the moving part 28 is lifted and the cap 40b closes the bottle 11 in the position shown in Figure 3c.

[0018] The next technological step of the bottle filling machine 10 is the washing of the bottle 11, which follows the removal of the cap 40.

[0019] For washing, as shown in Fig. 1 the 11 bottle 11 is turned by 180° about an axis perpendicular to the plane of the drawing by a gripping device not shown. In Figure 4, the bottle 11 is shown in the initial, partially rotated and fully rotated positions. Figure 2 shows a step motor 14 mounted on the bottom of the support plate 12 to provide the torque required for rotation. Figure 4 shows the same in enlarged scale. In the initial position we see bottle 11a, in the intermediate position bottle 11b and finally in the washing position bottle 11c. The rotation in this case is towards the inside of the automatic bottle filler 10 and not laterally as in the solution described in the earlier cited patent HU231312, and thus the utilization of space is now much more favorable. The washing itself is carried out in the same way as in the known solution, i.e. by spraying detergent into the opening of the bottle 11 and then rinsing. After washing, the bottle 11 is rotated back to its original position, as shown by the bottle position 11a.

[0020] The next technological step is the filling of the 11 bottles, which is carried out by the filling device 50 shown in Figures 2, 5 and 6.

[0021] Prior to filling, the customer decides which of the liquid options of the filler 10 must be selected. Accordingly, the filler 10 stores as many different cleaning liquids as most customers need. In the exemplary case, four different filling liquids are available and the corresponding filling liquids are stored in respective containers located at the bottom of the bottle filler 10. In figure 2, containers 51, 52 are shown, the other two containers are located behind the containers 51, 52 and are therefore not visible. Containers 51, 52 in the exemplary case have a capacity of 20 liters. For the filling step the central control unit 90 moves the filling device 50 into the axis line of the bottle 11 to be filled.

[0022] The filling device 50 has a stationary part 53 and a driven moving part 54. It is noted that the stator 53 can be combined with the support plate 23 of the cap remover 20, which simplifies the design. The purpose of the movement is to ensure that the filling liquid is always introduced into the bottle 11 below the momentary liquid level, to avoid foaming which would prevent filling. The movement is carried out by a motor 55 associated with the stationary part 53, which rotates a threaded spindle 58 driven by a belt 57 in accordance with the desired direction of movement. The moving part 54 is associated with a long filling stem 59 guided by a guide bush 60. The components of the stationary part 53 are held together by a support 56.

[0023] A top view of the filling stem 59 is shown in Figure 6, to which respective flexible tubes from each liquid tank are connected via respective valves not shown in the drawing and respective pump are built into the tubes, which are also not shown. The ends of the four pipes are connected to the pipe stubs A, B, C and D on the top of the filling stem 59. The filling is carried out in such a way that the motor 55 of the filling device 50, which is positioned in the axis line of the filling stem 59, moves the filling stem 59 downwards till the bottom of the bottle 11 to be filled, when the central control unit 90 opens both the valve and the pump in the tube which leads to the selected liquid tank by the user, and the filling process of the bottle 11 is initiated. The weight of the bottle 11 is measured by the scale 13 shown in Figure 2, which also supports the bottle 11. As the filling progresses, the filling stem 59 gradually moves upwards, but its bottom remains always 10 to 15 mm under the surface of the liquid. When the required fill is reached (as checked by the scale 13), the fill control pump and its associated valve are closed, and the motor 56 moves the valve stem 59 to its highest position again, after which the filling device 50 can be moved out of the space above the flask 11.

[0024] The next step is to screw the cap 40 back onto the 11 bottle as described above, following the disinfection of the cap 40 with ozone.

[0025] During the technological operations described so far, the bottle 11 stayed always in its initial position and during filling, it was possible to apply the required label 15 to the outer surface of the bottle 11 (Figure 2) containing the indication of the type of the filled liquid, the end of the guarantee period and other data relevant for use.

[0026] The printing process directly onto the surface of the bottle, although possible, would be a rather complex task, because under the given conditions, where there are many operations to be performed on the bottle 11and the equipment takes up a lot of space near the bottle 11, there will be no space left for a printer, or a very special printer design would be needed. Therefore, according to the invention, the task of label printing at the bottle filler 10 has been separated from the task of applying the label onto the bottle 11. Since the containers 51, 52 have a given volume Vt and the volume Vf of the bottle 11 is much smaller, one container is suitable for feeding Vt/Vf = n bottles. Among the labels 15, one of the most important pieces of information is the date of manufacture of the liquid in the container and the associated guaranteed expiry date, and this information is available at the manufacturer when the containers are filled. It follows that the simplest way is to produce n-number of sperate self-adhesive labels on a long substrate when a container is filled, by using a suitable printer, and to apply the labels on the pre-made labelled tapes to each bottle as it is filled, using a label applicator 70 device that helps to apply the labels onto the bottles. Figures 7 and 8 show a front view and a top view of the label applicator 70.

[0027] The label applicator 70 has a stationary part 71 and a moving part 72. The stationary part 71, in accordance with the fact that in the exemplary case the flask 11 can be filled with four different liquids, comprises respective separate stationary parts 71a, 71b, 71c and 71d for each liquid, which are of the same configuration and are arranged one behind the other as shown in Figure 8. Each of the four stationary parts 71 listed herein is provided with a label strip 73 for the cleaning fluid in the container to which it is associated (Figure 9), consisting of a carrier tape 74 and a pre-printed n-number of self-adhesive (i.e. adhesive backed) labels 75 applied to it at equal intervals, wherein the number of the labels is n = 10 in the example. The carrier tape 74, which is made of a material such that the adhesive adheres to it only slightly, has a relatively long label-less retracting section 76 at the front.

[0028] As mentioned above, the label strips 73 are produced as each container tank is filled, and the labels 75 assigned to them bear the prescribed inscription specific to the cleaning fluid in the associated container. The application of the labels consists of applying the appropriate labels 75 to the surface of the bottles 11 that are being filled, facing the label applicator 70.

[0029] The construction of the stationary part 71 of the same design is shown for the stationary part 71d, which comprises a Z-shaped vertical plane support plate 78, a brake roller 79 behind it, a belt guide 80 terminating in a pointed wedge in front (left in Figure 8), and a moving roller 81 with a vertical axis positioned behind it, the axis of which is connected to the motor 77 shown in Figure 7, which is purposefully a step-motor. The height of the elements mentioned here is slightly greater than the width of the label tape 73.

[0030] The moving part 72 is shown in Figure 8 in two positions, namely when it is in front of the stationary part 71b in the label-applying position and when it is in front of the stationary part 71d, but only one of these moving parts 72 is present in the label applicator 70. During use, the movable portion 72 is movable in the direction of the double arrow 82 shown in Figure 8, i.e. it can move closer and further away from the bottle 11, and the label is applied to the movable portion 72 in the position opposite the stationary portion corresponding to the cleaning liquid loaded. The moving part 72 comprises a first cylinder 85 with a vertical axis rotated by a motor 83, a fan 84 which has a suction effect, i.e. it directs air in the direction of the arrow 87 shown in Figure 8, and a second cylinder 86 similar to the cylinder 85. The front surfaces of the cylinders 85 and 86 are ribbed, i.e. they consist of a number of discs separated by a space between them, so that the suction effect produced by the fan 84 is also acts through them. The surface of the discs is made of silicone rubber or other flexible soft material so as not to damage the labels on the discs. The opening of the fan 84 is surrounded by a frame 88, the height of which is slightly less than the height of the label 75 and prevents the label 75 from penetrating the mouth of the fan 84. Preferably, this mouth opening is bridged by horizontal wires spaced a given distance apart, which support the rear (printed) surface of the label 25. These are not shown in Figure 7 due to their small size.

[0031] The procedure for applying the label is described for the label strips 73 on the stationary part 71b. When the container associated with the stationary part 71b is filled, the corresponding label strip 73 is attached to the two sides of the strip guide 80 by means of the relatively long retracting section 76 in such a way that, as indicated by the line in bold on the stationary part 71b in the drawing, first that section is inserted between the brake roller 79 and the bottom of the strip guide 80 (as shown in Figure 8 at the bottom but in reality it is in front), and then, proceeding from right to left, pass it in front of the edge of the guide 80 terminating in the tip and there reversing the direction by 180° to the upper (rear) surface of the guide 80 from left to right, and thread the end under and slightly beyond the moving roller 81. This completes the retraction. At this point, the first label has not yet reached the tip of the tape guide 80. When the label is applied to the moving part 72, the fan 84, the motor 83 and the motor 77 are started or stepped. The motor 77 moves the label ribbon 73 in the direction of the left-right arrow outlined above the ribbon guide 80 on the stator 71b, the movement of which is braked by the brake roller 79 to such an extent that the carrier ribbon 74 is stretched but not yet torn when it is turned over the tip of the ribbon guide 80.

[0032] When, during the indicated movement of the label tape 73, the next label 75 in line reaches the leading edge 80 of the tape, the carrier tape 74 is subject to a sharp 180° change of direction due to the high flexibility of the material, but the material of the label 75 on the top of it has a much higher bending resistance (stiffness) and a low adhesion to the carrier tape 74 under it, and therefore comes off, although it is slightly rotated in the direction of the curvature of the carrier tape 74 below. The label 75 is then with its printed, i.e. outer surface outside. At the same time, it is also subjected to the pulling force from the direction of the moving part 72, because the fan 84 exerts a suction effect over a large surface area, and this causes the label 75 to detach from the carrier strip 74 in such a way that it moves towards the first roller 85, and its rotation from right to left causes the detachment process to continue, and the force required for the detachment to increase, because the suction effect is by then acting over a substantial part of the surface area of the label 75. Therefore, the label 75 occupies the entire front surface of the stationary part 72 in such a way that its adhesive-coated surface faces the bottle 11. At this point, the motor 77 is stopped and the label strip 73 is ready for the next filling of the stationary portion 71b to transfer the next label to the moving portion 72 in the manner described herein.

[0033] The labels 75 on the front of the moving part 72 are applied to the bottles 11 by moving the moving part 72 to the bottles 11 and applying a small pressing force. By this time, the fan 84 and the motor 83 are in a stopped state and the adhesion between the surface of the bottle 11 and the adhesive coated surface of the label causes the label 75 to be securely attached to the bottle 11.

[0034] Although the solution has been described for rectangular bottles with a flat surface, there is no reason why the front surface of the 72 moving parts cannot be curved, so that the label can be applied to a cylindrical surface if the radius of the curve of the 72 moving parts is the same as the radius of the curve of the cylindrical bottle.

[0035] The process ends with the 40 caps being screwed back on using the 2cap remover 20.

[0036] We now refer to Figure 10, which shows a block diagram of the control of the bottle filler 10 vending machine. The processes are controlled by the central unit 90 as described and are therefore in control-operating relationship with the cap remover 20, the cleaning unit 100 that operates the step motor 14 and the pumps for washing, the filling device 50, the label applying device 70, and a handling unit 110 and, where applicable, the central system 120 of the store or sales area in which the automatic bottle filler 10 is located. The operations which are or can be carried out by the handling unit 110 are substantially identical to those described in the cited Hungarian patent, namely the operator identifies himself, indicates which cleaning liquid he wishes to be filled, then indicates his payment options, inserts the bottle 11 into the opening compartment of the bottle filler 10 according to the information displayed, and then, waits until the filling is completed, removes the labelled, filled and ready bottle 11 through the open compartment door.

[0037] The operations described here, and the overall filling time is between 1.5 -3 minutes, that worth the waiting to save the environment and reuse the large bottle 11.
