Description
- This application claims the benefit of priority under 35 U.S.C. §119 of European
Patent Application EP 10 160 122.7 filed Apr. 16, 2011, the entire contents of which are incorporated herein by reference. - The present invention pertains to a device for filling processing stations with a pumpable working material (operating substance). The present invention pertains, furthermore, to an arrangement for filling processing stations with a pumpable working material, with a central tank for the working material and with two or more processing stations and a feed line for feeding the working material to one of the processing stations.
- Even though the present invention is suitable for all pumpable working materials, i.e., bulk materials, gel-like or pasty substances or liquids, a concrete application of the present invention is the preparation of hot-melt adhesives for a heat-sealing means, for example, in packaging machines. The heat-sealing means is thus a processing station in this case. The hot-melt adhesive is provided as bulk material, especially in the form of granular material, also designated as pellets, and is usually stored in tanks directly at the heat-sealing means. Each heat-sealing means has its own tank with a corresponding capacity, into which the granular material is filled. The drawback in this case is that the environment of the tank is very hot, such that the personnel may be burned while filling the tank. Moreover, in the case of high-performance heat-sealing means, the tank has to be refilled very frequently, which requires a corresponding workforce. There is also the risk that sufficient granular material is not present in the tank, which may lead to defects in the bond and to production rejects as well as to production losses. Furthermore, it occurs that granular material is spilled during the refilling of the tank and the environment becomes contaminated with it. It should be taken into consideration here that spilled material is always also mixed with dust because of abrasion, which contaminates the environment as well. Moreover, spilled granular material may come into contact with hot parts of the heat-sealing means and then melt. The heat-sealing means is further contaminated as a result of this. This is always undesirable. Contaminations are especially of special concern in packaging machines for food.
- To avoid these drawbacks, in practice the granular material was already prepared in drums and the tank of the heat-sealing means was refilled from the drum via a corresponding refill line. Exactly one tank is assigned to each drum in this case. The workforce is reduced here, since the drum has a greater capacity than the tank. However, the personnel must still always monitor that the drums are replaced in a timely manner. Moreover, the conveying track, via which the granular material is conveyed, is highly limited in this variant, such that drums have to be set up close to the respective heat-sealing means. These drum locations are often not easily accessible sites. Moreover, it has been shown in practice that the granular material easily becomes lumpy in the drums.
- The arrangement according to the present invention includes a device with a transfer chamber that is assigned to a central tank for the working material. the transfer tank of the invention may be provided in a combination with features according to DE 20 2009 005 561 U1 which is hereby incorporated by reference in its entirety. The transfer chamber is assigned to the processing station, in such a way that the working material can be conveyed at first from the central tank into the transfer chamber and from there to the processing station.
- By the working material at first transferring from the central tank to a transfer chamber, i.e., a preportioning of the working material is performed so to speak, greater conveying paths can also be accommodated. For this reason, the central tank may be arranged at an easily accessible site as well, such that it can be refilled in a simple manner. Therefore and because of a greater capacity, the central tank can be refilled almost free from contaminations and arranged at a distance from the processing stations, i.e., mainly the heat-sealing stations, such that the risk of injury, especially the risk of getting burned, is avoided. Contaminations that may still possibly occur involve contaminants that pass at a distance from the processing station and can be easily removed. In this case exactly one processing station may be present that is supplied from the central tank. However, the present invention is mainly intended for supplying a plurality of the processing stations, including a heat-sealing means according to the above example, from a common central tank with the working material, granular material of the hot-melt adhesive. In this way, only one more central tank needs to be monitored, as a result of which the operating cost is considerably reduced.
- An object of the present invention is to provide an effective transfer chamber for an arrangement for supplying processing stations with pumpable substances, and especially for processing stations according to DE 20 2009 005 561 U1.
- For this purpose, a bottom surface deepening towards a sump in a funnel-like manner is provided at the bottom of the transfer chamber. The sump may be provided in the center in the bottom of the transfer chamber, but also off-center, for example, laterally. The sump should be embodied as a blind hole and have a diameter that corresponds approximately to the internal diameter of the discharge opening or of the feed tube. Also, as a result of this, the working material can be easily blown out of the transfer chamber. Conveying tracks (paths) of about 100 m and a height difference of up to 25 m can be overcome with such an equipped pilot plant. This alternative embodiment of the transfer chamber is also conceivable independent of the device and arrangement according to the present invention.
- The transfer chamber can be closed upwards towards the central tank by means of a ball valve. As a closing means, such ball valves have a ball provided with a passage hole. If this ball is brought into its closed position, the granular material remains behind in the passage hole, which then becomes lumpy already at room temperature and consequently clogs the passage hole even in the open position. To avoid this, provisions are made according to a variant that the closing means is also open towards the transfer chamber even in the closed position. As a result of this, granular material remaining behind in the closing means can always flow out into the transfer chamber and thus not clog the closing means.
- According to the arrangement according to the present invention, two or more transfer chambers may be assigned to the central tank, whereby a processing station is respectively assigned to each transfer chamber. This may result in that a particular line for the working material is always guided to a particular processing station from each of the transfer chambers. Thus, there is a star-shaped connection of the processing stations to the central tank. However, it is also conceivable that the central tank is provided with only one transfer chamber, to which two or more processing stations are then assigned. In this case, the transfer chamber is connected to a concrete processing station by means of switches in the line, respectively, such that only one concrete line is always switched between the transfer chamber and the respective processing station. This variant may be designated as a tree structure, in which, starting from the transfer chamber the trunk, a plurality of branchings arise. Of course, in the tree structure it is also possible to assign two or more transfer chambers to the central tank, such that an own tree structure then starts from each transfer chamber. It is also conceivable to provide transverse connections under the individual tree structures, such that, as an option, two processing stations arranged within the one tree structure may also at the same time be supplied with working material, if this should be necessary. As already indicated above, it is important only that at each point in time only one entirely particular path from one of the transfer chambers is always switched to an entirely defined processing station for the working material. In the simplest case, this can be embodied by a ring line that starts from a transfer chamber and ends in another transfer chamber. Then, a line from the processing station to be filled is always switched to the transfer chamber placed next to it—once around to the right and once around to the left, such that two processing stations can always be filled at the same time.
- According to a variant of the arrangement according to the present invention, provisions are made that the working material is fed from the transfer chamber at first to a means for separating the pressurizing means, i.e., for example, compressed air, and is conveyed from there in an unpressurized manner into the tank of the processing station. In the prior-art process mentioned in the introduction, in which the granular material of the hot-melt adhesive was conveyed from the drum by means of compressed air into the tank of the processing station, this also led to a cooling of the heat-sealing means. As a result of this, the heat-sealing means was partly cooled below the melting point of the hot-melt adhesive, which led to disturbances in the operating sequence. Since, according to the present variant, the compressed air is already separated beforehand and the working material flows into the tank in an unpressurized manner, this risk is avoided.
- The present invention is explained in detail below based on an exemplary embodiment shown in the drawing. The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which preferred embodiments of the invention are illustrated.

FIG. 6 is a perspective view showing a ventilating means for the arrangement according toFIG. 5 ; and -
FIG. 7 is a perspective top view showing a cover for a working material tank of a processing station. - Referring to the drawings in particular, the arrangement shown in
FIG. 1 includes acentral tank 10 withtransfer cartridges 11 arranged under the central tank.Central tank 10 is mounted oncolumns 12 by means ofvibration dampers 13 on abasic frame 14. Furthermore, acontrol box 15 for controlling the device is assigned to thecentral tank 10. -
FIG. 1 shows, as representative of a random number of processing stations, a processing station, in particular a heat-sealing means 16. A working material, a granular material of a hot-melt adhesive in the present case, is fed by means of afeed line 17 at first to a ventilating means 18, the significance of which will still be explained further below. This ventilating means 18 is located above the heat-sealing means 16, specifically above a tank of same, so that the working material can flow in an unpressurized manner from the ventilating means 18 into the tank of the heat-sealing means 16. Thefeed line 17 is connected to thetransfer cartridge 11 via afeed tube 28. -
FIGS. 2 and 3 show atransfer chamber 42 according to the invention, which replaces thetransfer cartridge 11 in the arrangement according toFIG. 1 . Thistransfer chamber 42 is embodied as a cylindrical, specifically a circular cylindrical, hollow body. Thetransfer chamber 42 has a bottom 43, which forms abottom surface 44, which deepens towards the center in a funnel-like manner and then passes over into acentral sump 45, embodied as a blind hole in the present case. Thetransfer chamber 42 is closed by acover 46, which has ascrew socket 47, at the top, i.e., at an end opposite the bottom 43. In the present case, thescrew socket 47 is provided with amale thread 48 on its outside, but may, in addition or as an alternative, also be embodied with a nut on its inside. Furthermore,screw socket 47 has apassage hole 49, which communicates with the internal cavity of thetransfer chamber 42. - A
ball valve 50, which has for this purpose anut 51 communicating with themale thread 48 of thescrew socket 47, is screwed onto thescrew socket 47. If thescrew socket 47 should have a female thread, theball valve 50 is, of course, provided with a corresponding male thread. All other prior-art connecting techniques, for example, a bayonet catch between the transfer chamber 41 andball valve 50, are also possible. Otherwise, the ball valve is embodied in the commercially available manner and is actuated via a motor actuation means 52. - At the bottom 43 of the
transfer chamber 42 is arranged adischarge tube 53, which communicates with a pressurizing means in the form of acompressed air nozzle 54, with pressurized air source, which is arranged in thesump 45 of the bottom 43. Thecompressed air nozzle 54 may be designed as a venturi nozzle and protrudes with its opening up to into thedischarge tube 53. Theend 59 visible inFIG. 2 within thesump 45 bends and extends downwards and communicates with a compressed air connection. The diameter of thesump 45 is approximately and preferably exactly as large as the internal diameter of thedischarge tube 53. -
FIG. 4 shows a bottom view of acentral tank 55, which is equipped with thetransfer chambers 42. In the bottom 58 of thecentral tank 55 there is provided a number of openings 57, to which thetransfer chambers 42 can be connected via theball valves 50. Furthermore, a vibrating means 60, with which thiscentral tank 55 is also equipped. - In the variant according to
FIGS. 2 to 4 as well, thetransfer chamber 42 is filled with a volume of the granular material, which corresponds to the volume that can be accommodated by the tank of the heat-sealingstation 16. For this purpose, theball valve 50 is opened in a time-controlled manner or via corresponding filling level sensors in thetransfer chamber 42, until the respective filling level in thetransfer chamber 42 is reached and theball valve 50 is then closed again. Now, a pressurizing means is sent to thecompressed air nozzle 54. The duration of the pressure surge is again measured in a time-controlled manner, so that thetransfer chamber 42 is completely emptied and the granular material is fed to the tank of the heat-sealingstation 16. Due to the pressure surge the granular material, as described above based on thetransfer chambers 42, is conveyed from thetransfer chamber 42. In this case, the flow in thetransfer chamber 42 is facilitated (the material breaks down) because of the special shape of the bottom 43 in thetransfer chamber 42, so that the granular material is accelerated at a high speed. In a pilot arrangement equipped with thistransfer chamber 42, the granular material could be conveyed a distance of approximately 100 m, and a height difference of 25 m could be overcome. - Ordinary ball valves have a ball provided with a passage hole as closing means. It has been shown that granular material may remain behind (in the valve) when the ball valve is closed. Therefore, in the present case, the
ball valve 50 is provided with a ball, which is provided with an opening, which is open towards thetransfer chamber 42 even in the closed position of the ball valve, such that the granular material can always flow from the ball into thetransfer chamber 42. For this, the ball can be provided with a corresponding groove or be embodied as a shell. - The device according to the present invention and arrangement according to the present invention were described above based on the example of supplying heat-sealing means with heat-sealing granular material, i.e., a bulk material. However, the present invention is suitable for all pumpable working materials, i.e., not only for bulk materials, but also for gel-like or pasty substances and liquids. The device according to the present invention and arrangement according to the present invention are also suitable for any other type of processing stations as heat-sealing means.
- Furthermore, according to the above exemplary embodiments, exactly one
transfer chamber 42 is always assigned to each processing station (heat-sealing station 16). As an alternative, it is also possible to assign two ormore transfer chambers 42 to aprocessing station 16. This may be sensible in very fast runningprocessing stations 16 with only a small tank, since then the tank is refilled from one of thetransfer chambers 42 from thecentral tank 10. In this case, an own (dedicated) or a common ventilating means 18 may also be assigned to eachtransfer chamber 42 depending on the needs. It is also possible that two ormore processing stations 16 are assigned to atransfer chamber 42, which are then assigned by means of switches to thetransfer chamber 42. It is important only that only oneprocessing station 16 is always presently assigned to thetransfer chamber 42. Such an arrangement is shown inFIG. 5 , which is based on thecentral tank 55 according toFIG. 4 and has thetransfer chamber 42 fromFIGS. 2 and 3 as a transfer chamber. Specifically, twotransfer chambers 42 are shown. Of course, thecentral tank 55 may also be provided with only onetransfer chamber 42 or even three ormore transfer chambers 42. - At first a
main pipeline 61, which branches into twomain branches first switch 62, starts from thetransfer chamber 42. Theswitch 62 is, like all other switches still to be described further below as well, embodied as a three-two-way ball valve. That is, a total of three lines are assigned to the ball valve, whereby in the present case one inflow and two outflows are provided, respectively, and in particular in the case ofswitch 62 the main pipeline as inflow and themain branches - The
main branch 63 ends at another switch 65.1, from which a branch line 66.1 branches off at an outflow. This in turn opens out in a switch 65.2, one outflow of which ends at a branch line 66.2. This goes on with a selectable number n of switches. In a similar manner, the second and possibly another othermain branch 64 opens out into a first switch 67.1, leads from the one first branch line 68.1 to another switch 67.2 and so forth until a selected number of m switches 67 is reached in this case as well. The respective other outflows of the switches 65 and 67 open out in a ventilating means 69, by means of which the compressed air used for transporting the working material from thetransfer 62 is removed. For this purpose, the ventilating means 69 has a tube-like,cylindrical filter 70, whose jacket surface is made of a filter material, a screen in the simplest case. The mesh size of the screen is such that the working material cannot pass through the screen, but the air transporting the working material can. A funnel-liketapered section 71, which opens out into adown pipe 72, is provided under thescreen 70. The internal diameter of thedown pipe 72 is smaller than the internal diameter of thefilter 70 because of the taperedsection 71. As a result of this, the working material is easily retained in the area of taperedsection 71, is thus slowed down in its speed, without leading to a complete clogging. Because of the easy retaining of the working material in the area of the taperedsection 71, the compressed air escapes through thefilter 70 and the working material flows in an unpressurized manner to theprocessing station 16. - The tanks of the
processing stations 16 are usually closed with a cover. In the case of heat-sealing machines, the cover is even insulated in order to minimize the escape of heat that is used to melt the hot-melt adhesive in the tank. Also within the framework of the present invention, the tank should therefore be closed with a cover, as this is shown schematically by thecover 73 inFIG. 5 . Thecover 73 itself is shown in detail inFIG. 7 . Thecover 73 has an opening (not visible inFIG. 7 ), through which the working material can flow. This opening is closed by acap 74, which in the present case is mounted pivotably about anaxis 75 at thecover 73. Another ventilating means 76, which likewise has acylindrical filter 77 as a jacket, similar to the ventilating means 69, is arranged at thecap 74. The downpipe 72 is connected to this ventilating means 76 at the top. With thecap 74 open, the ventilating means 76 is in alignment with the opening in thecover 73, such that the working material can flow through the opening. As soon as the tank is filled, thecap 74 is pivoted into the closed position under elastic deformation of thedown pipe 72. Thecap 74 now closes the opening in thecover 73. - However, vapors may escape from the tank of the processing station even with the
cap 74 closed. To this end, a collecting means 78, in which vapors are collected and are disposed of, for example, once daily by cleaning the collecting means 78, is assigned to thecap 74 in its closed position. As an alternative, an insulating plug may possibly also be provided here, which is charged into the opening incover 73 withcover 73 insulated from the underside and thus provides for a continuous insulation as much as possible without heat bridges. - The
cap 74 is actuated by apneumatic cylinder 79 in a manner known per se. It is understood that themain branches processing stations 16, but can themselves branch off into other forearms. Also, only a single main branch may be provided, which then connects directly to thetransfer chamber 42. Furthermore, it is, of course, also conceivable to mix the different concepts of the arrangement according toFIG. 1 andFIG. 7 with one another and to assign them to the same central tank. - While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
