Description

METHOD FOR CONTAMINATION-AVOIDING DRAINING RELATING TO FILLING A CONTAINER

The invention relates to a method for the contamination-avoiding emptying or filling of a container of the type mentioned in claim 1. Further, the invention relates to a clamping device for carrying out the method according to claim 13.

The starting materials, such as raw materials or components, for industrially produced products are increasingly demanding. These concern

for example, the purity of the starting materials and / or, in particular for active ingredients, their concentration. Highly concentrated starting materials can also be toxic. For a transport of such starting materials, these are filled into correspondingly tight containers and the containers are emptied again at the place of use. In doing so, it is necessary to ensure contamination-avoiding emptying as well as filling to protect the user and the environment. From WO 2010/052489 A1 a method for the contamination-avoiding emptying or filling of a container is known, wherein the container and the container each have a sleeve-shaped connection region. Here, a transfer sleeve is used, which has a sleeve-shaped base body with a first free, open end and with a second free, open end and with two side sleeves which protrude laterally from the main body and are open to this.

The first end of the base body is slipped over the closed with a closure portion connecting portion of the container and fixed by a clamp at this. The second end of the base body is slipped over the closed with a closure portion connection area of the container and also fixed by a clamp at this. By the side arms, the closure sections are removed from the connection areas and in the

Pulled in side arms. Subsequently, the transfer sleeve is moved in the direction of the container and in the direction of the container until the areas with the side arms each come to lie at the height of the respective connection area. After emptying or filling of the container, the end regions of the transfer sleeve are displaced again, so that the side arms outside the connection region of the container and the container to are coming. The transfer sleeve is closed in the areas between the side arms and the free ends of the connection areas, each with a closure element. The closure elements are then severed, so that the connection areas of the container and the container are closed again. The remaining, also closed middle section of the transfer sleeve is disposed of.

A disadvantage of this known solution is that this method for

Contamination-avoiding emptying or filling of a

Container with a flexible, sleeve-shaped connection area, such as a Big-Bag or FIBC (Flexible Intermediate Bulk Container), is not suitable.

From EP 1 708 941 B1, a method for the contamination-avoiding emptying or filling of a container with a flexible, sleeve-shaped connection region is known. On the container is a

Hose film reservoir provided. For connecting the free end portion of the tubular film portion of the tubular film storage container with the free end portion of the terminal portion of the container is first the

Hose film section fixed by means of an Axialdichtrings at the free end of the rigid connection portion of the container. Then the free end of the

Tubular film portion passed through an annular Blähringaufnahme and guided the free end of the terminal portion of the container through a mating ring and wrapped around this. Subsequently, the counter ring is pushed into the Blähringaufnahme and emptied or filled the container. The further handling essentially corresponds to the procedure as it is in

Related to the aforementioned WO 2010/052489 A1 has been set forth. A disadvantage of this known solution is that a tubular film storage container must be provided on the container. In addition, this method requires a variety of complex steps, which in a non-compliance with the exact procedure cause the tightness between the

Hose film section and the connection area of the container created connection is not guaranteed.

Object of the present invention is thus to provide a method for

Contamination-avoiding emptying or filling of a

To provide containers with a flexible, sleeve-shaped connection area, which does not have the aforementioned disadvantages and which in particular ensures easy handling with a high degree of safety for the user and the environment.

This object is solved by the features of independent claim 1. Advantageous developments are in the figures and in the dependent

Claims set forth.

According to the invention, the method for the contamination-avoiding emptying or filling of a container with a flexible sleeve-shaped connection region comprises: the creation of a sleeve connection between the connection region of the container

Container and a transfer sleeve having a sleeve-shaped base body having a first free, open end and a second free, open, the first end opposite end. In this case, a mounting ring is provided.

Subsequently, the free end region of the connection region of the container is passed through the mounting ring. Then the free end of the

Connection area of the container folded around the mounting ring. Subsequently, the first end of the main body of the transfer sleeve is slipped over the folded end portion of the terminal portion of the container and the mounting ring, so that the main body of the transfer sleeve partially with the

Terminal area of the container overlaps with an overlap length. Now, in the region of the mounting ring, a fixing element, for example a clamping ring or a clamping ring, is provided, which covers the overlapping end region of the

Basic body of the transfer sleeve comprises. For fixing the transfer sleeve to the connection region of the container and thus the connection created, the fixing element is clamped.

Furthermore, the method comprises arranging the second end of the main body of the transfer sleeve on a connecting element, in particular on one

Discharge nozzle or on a filling nozzle of a container. Subsequently, the container is emptied or filled. With this method, a simple connection between the container and the container is created, which reliably prevents contamination of the environment. In addition, this method includes only a small number of simple to be executed steps, which are executable after a brief introduction by a user.

The recessed, remaining on the container section additionally secures the

Closure of the container, which is particularly advantageous after a filling of the container and for subsequent transport for a sufficiently tight closure of the container.

Transfer sleeves already on the market can be used in this process, which consist essentially only of film material. The

Arrangement of endless tubular films, which are expensive and have a large footprint, is unnecessary with the inventive method.

The overlap length preferably corresponds to 0.5 times to 3.0 times the inner diameter of the transfer sleeve, with the first end of the main body of the transfer sleeve being slipped over the folded end region of the connection region of the container until this overlap length is reached. This results in a sufficiently large overlap, which ensures a tight sleeve connection. Advantageously, for example, provided on the base body of the transfer sleeve, spaced from the first end of the same a mark indicating the minimum overlap.

Preferably, before the slipping over of the first end of the main body of the transfer sleeve, the free end of the connection region of the container is at least partially folded back, whereby the corresponding end region of the container

Connection region of the container on the outside of the mounting ring is double-layered.

The free end of the connection region of the container is remote from the container.

By this additional process step, the safety and tightness of the created sleeve connection is further improved.

The folding back of the free end of the connection region of the container advantageously takes place about a free end of an auxiliary mounting ring whose free end advantageously faces the container. By means of the auxiliary mounting ring, the refolding can be carried out easily and with a high quality, which has an advantageous effect on the safety and tightness of the created sleeve connection.

Preferably, a sealing element, for example an O-ring made of an elastic material, provided in the region of the mounting ring, which is the Tightness and thus the safety of the created sleeve connection additionally improved. Advantageously, such a sealing element is provided between the outside of the main body of the transfer sleeve and the fixing element, so that at the same time the sealing element is fixed in the desired position during clamping of the fixing element.

Preferably, a connection portion is provided at the second end of the base body of the transfer sleeve, wherein the connection portion is slipped over the free end of the discharge nozzle or the filling nozzle and fixed thereto. The connection portion is advantageously designed such that a secure and tight connection is created in this area. This connection is advantageously formed non-positively and / or positively.

Preferably, at the discharge nozzle or on the

Filling nozzle provided at least one receptacle for the connection portion of the transfer sleeve, in which the connection portion is fixed. This ensures a secure connection of the second end of the main body of the transfer sleeve to the discharge nozzle or on the

Filling adapters. Advantageously, the recording runs circumferentially around the

Discharge nozzle or the filling nozzle. Also advantageous are at least two mutually spaced receptacles for receiving the

Connecting section of the transfer sleeve on the discharge nozzle

or provided on the filling neck, so that the

Connecting portion of the transfer sleeve in two different positions on the discharge nozzle or on the filling nozzle is securely fixed. Preferably, the discharge nozzle or the filling nozzle is closed with a closure portion and on the transfer sleeve is at least one of the main body of the transfer sleeve laterally projecting and to this

Base body provided open side sleeve. After setting the

Transfer sleeve on the discharge nozzle or on the

Filling nozzle, the closure portion by means of an access through the

Side sleeve removed from this and pulled into the side sleeve. By this measure, a contamination of the environment in the arrangement of the container at the discharge nozzle or at the filling nozzle is reliably prevented at each step. Advantageously, then the Side sleeve closed in a region between the outside of the base body of the transfer sleeve and the closure sleeve located in the side sleeve with a closing element, so that during the subsequent emptying or filling of the container, the removed closure portion does not obstruct the corresponding operation or no abzufüllendes

Material remains in the side sleeve. The second mentioned point is essential in particular for expensive starting materials or materials to be filled.

Preferably, the sleeve connection is pushed over the free end of the discharge nozzle or the filling nozzle before emptying or filling of the container until the sleeve connection and advantageously the mounting ring on the discharge nozzle or on the

Filling connection is present. The mounting ring is advantageously designed such that it bears non-positively in the pushed-state on the discharge nozzle or on the filling nozzle. The between the

Sleeve connection and the second, arranged at the discharge nozzle or at the filling nozzle end of the transfer sleeve existing portion of the transfer sleeve is in the aforementioned displacement of the

Sleeve connection pushed together outside of the drainage nozzle or the filling nozzle. The connection between the

Transfer sleeve and the discharge nozzle or the

Filling nozzle is unloaded. The flexible connection area of the container is connected directly to the discharge nozzle or to the filling nozzle. A big bag or FIBC as a whole and thus also its flexible connection area is usually made of a robust, durable foil. Therefore, this type of connection between the container and the discharge nozzle or the filling nozzle has a high

Compressive strength of the system during emptying or during filling on. In addition, the transfer sleeve serves here only as a contamination limit when arranging or when removing the container and is in

Substantially hardly or during the emptying process or filling not material contact. Therefore, the transfer sleeve can be made of a comparatively favorable material.

Preferably, an outgoing from the free end of the drainage nozzle or the filling neck mounting ring receiving on the discharge nozzle or provided on the filling nozzle for receiving the sleeve connection or the mounting ring to ensure a secure connection in this area. Advantageously, the mounting ring receiving the outside of the drainage nozzle or the filling nozzle and arranged circumferentially, which allows a simple sliding of the sleeve connection or the mounting ring and avoids hindering the subsequent emptying or filling process through the sleeve connection.

Alternatively or in addition to the aforementioned mounting ring receiving a sealing device on the discharge nozzle or on the

Filling nozzle provided for sealing between the pushed sleeve connection and the discharge nozzle or the filling nozzle. The sealing device is advantageously on the outside of the discharge nozzle

or arranged of the filling nozzle and is for example of an O-ring or a z. B. formed by means of air or fluid expandable element.

Preferably, the sleeve connection is pushed by means of a tensioning device over the free end of the discharge nozzle or the filling nozzle to the system of the sleeve connection or the mounting ring on the discharge nozzle or on the filling nozzle. The clamping device ensures a safe investment of the sleeve connection or the mounting ring on the discharge nozzle or on the filling nozzle. Since by means of the clamping device, a higher force than in a manual displacement of the sleeve connection can be applied, the tolerances between the sleeve connection or the mounting ring and the discharge nozzle or the filling nozzle can be kept small, resulting in a tight and secure connection of the container to the discharge nozzle or on the Filling nozzle ensured. Advantageously, when clamping the clamping device, the sleeve connection or the mounting ring at least partially to the

Discharge nozzle or pressed against the filling nozzle. This clamping device is advantageous in the area of the drainage nozzle

or the filling nozzle provided on the container. Further advantageously, by means of this clamping device, the sleeve connection is fixed to the discharge nozzle or to the filling nozzle, whereby an additional assurance of the connection of the transfer sleeve in the region of the drainage nozzle or the filling nozzle is given. Preferably, after the emptying or filling of the container, the sleeve connection is pushed in the direction of the free end of the discharge nozzle or the filling nozzle, so that it comes to rest outside the discharge nozzle or the filling nozzle. This simplifies the further handling of the transfer sleeve and / or the container.

Preferably, after the emptying or after the filling of the container, the transfer sleeve is closed on both sides of the sleeve connection by means of at least one closure element and then the

Closing element is severed in such a way that a partial closure element closing the corresponding sections remains on both sides. This ensures a secure closure of the sections of the transfer sleeve and the middle section of the transfer sleeve remaining on the discharge nozzle or on the filling nozzle and on the container.

Alternatively or additionally, in each case two closure elements are arranged on both sides of the sleeve connection and the transection of the transfer sleeve is made between two adjacent closure elements. With this measure, a secure closure of all separated sections of the transfer sleeve and thus also of the container is ensured.

A clamping device for carrying out the aforementioned method comprises a mounting plate, a projecting from the mounting plate guide means and guided by the guide means receiving plate which aligned parallel to a plane spanned by the mounting plate level, relative to the mounting plate slidably and with a receptacle for the

Sleeve connection is provided. This clamping device is simple in construction and operation. In addition, higher forces can be applied to the arrangement of the sleeve connection with such a tensioning device than is the case with a merely manual arrangement. The fastening plate has, for example, fastening openings through which fastening means for fixing the tensioning device to a container or to a substrate can be passed. Alternatively or additionally, suitable fastening means are provided directly on the mounting plate for the corresponding fastening.

The guide device advantageously comprises at least two guide rods and along the same displaceable guide elements, such as associated with the receiving plate guide sleeves. Such a guide device prevents when moving the receiving plate relative to

Mounting plate can tilt or block this. The guide means may also comprise more than two guide rods and guide elements of corresponding number, which is advantageous in particular in a clamping device with large dimensions.

The receiving plate is connected according to the configuration of the guide means with the guide elements. Next is the recording for the

Sleeve connection advantageously designed such that the sleeve connection is easy and under different orientation of the clamping device can be arranged at this. Advantageously, the receiving plate has a substantially annular

Design on. Particularly advantageous are provided on the inner circumference of the annular receiving plate opposing insertion recesses. This creates a free space through which the sleeve connection can be introduced from the side of the receiving plate facing away from the mounting plate into the space between the receiving plate and the mounting plate. By tilting the sleeve connection this comes inside, d. H. at the

Mounting plate facing side of the receiving plate, at least during

Move the mounting plate with the same in plant. The inner diameter of the annular receiving plate outside the insertion recesses is smaller than the outer diameter of the usable with the clamping device

Sleeve connection selected. Preferably protrudes from the mounting plate in the direction of the receiving plate from a discharge nozzle or a filling nozzle. Thus, the terminal portion of the transfer sleeve with respect to this defined

Discharge nozzle or filling nozzle are formed and it does not have a variety of different transfer sleeves for different configured emptying nozzle or filling nozzle are provided. This tensioning device is advantageously located above the outlet on the

Container arranged.

Preferably clamping elements are provided for clamping the receiving plate to the mounting plate, whereby the sleeve connection and / or the

Transfer sleeve securely on the discharge nozzle or on the

Filling nozzle is fixed. The clamping elements comprise, for example, a combination on eyelets and hooks, which are relative to each other z. B. by means of a

Clamping levers are braced.

FIGS. 1 to 6 show individual process steps of the process according to the invention for contamination-avoiding emptying or

Filling a container 16.

The container 16 has a flexible, sleeve-shaped connection region 17 with a free end region 18.

The transfer sleeve 21 has a sleeve-shaped base body 22 with a first free, open end 23 and with a second free, open end 24, which is opposite to the first end 23. At the second end 24 of the main body 22 of the transfer sleeve 21, a connection portion 25 is provided. The connection section 25 is formed in this example by a thickening of the material at the second end 24 of the main body 22. Alternatively, an advantageously elastic element may be provided as a connection section at the second end 24 of the main body 22. From the base body 22 of the transfer sleeve 21 projects laterally from a side sleeve 26, which is open to the base body 22 out. At its free, the body 22

remote end 27, the side sleeve 26 is closed.

To create a sleeve connection 31 between the connection region 17 of the container 16 and the transfer sleeve 21, a mounting ring 32 is first provided. The mounting ring 32 is made of cardboard in this example. The free end portion 18 of the terminal portion 17 of the container 16 is then passed through the mounting ring 32 and folded around the mounting ring 32 so that the free end of the folded end portion 18 is aligned in the direction of the container 16 (Figure 1). Subsequently, the first end 23 of the main body 22 of the transfer sleeve 21 slipped over the folded end portion 18 of the connection portion 17 of the container 16 and the mounting ring 32. The base body 22 of the transfer sleeve overlaps in regions with the connection region 17 of the container 16 with an overlap length L, which in this example is approximately 1 times that of FIG

Inner diameter of the transfer sleeve 21 corresponds.

In the region of the mounting ring 32, a fixing element 36 is provided, which comprises the overlapping end region of the main body 22 of the transfer sleeve 21. The fixing element 36 comprises two semi-circular partial elements 37, which can be connected to one another and clamped to the connection region 17 of the container 16 by means of a clamping mechanism, not shown here, for fixing the transfer sleeve 21. Each sub-element 37 has on its coming into contact with the transfer sleeve 21 in page 38 has a recess which is formed for receiving area by area of the mounting ring 32. Between the outside of the main body 22 of the transfer sleeve 21 and the fixing element 36, a sealing element 41 is provided in the region of the mounting ring 32. The sealing element 41 is formed in this example as an O-ring made of an elastic material.

As shown in Figure 2, the container 16 is now ready to be attached to a

Discharge nozzle or filling nozzle 46 to be connected as a connecting element, for example, a container for the emptying process or filling to be performed. The filling nozzle 46 is still closed with a closure portion 51. This prevents that material to be filled can escape undesirably from the container into the environment.

In the following, only the example of filling the container 16 is executed. However, the statements made in this context also apply to a method in which the container 16 is emptied, by analogy.

FIG. 3 shows the method step in which the second end 24 of the main body 22 of the transfer sleeve 21 has been arranged on the outside of the filling neck 46. On the outside of the filling nozzle 46 are spaced from the free end 47, two spaced apart receptacles 48, 49 are provided. The receptacles 48, 49 are formed as grooves and run circumferentially. Further, on the outside of the filling neck 46, a mounting ring receiving end 50 extending from the free end 47 of the filling neck 46 is provided, which is designed as a circumferential groove open towards the free end 47.

The free end 52 of the closure portion 51, which closes the filling nozzle 46, has a connection portion which lies in the receptacle 48 which is closer than the receptacle 49 to the free end 47 of the filling nozzle 46. The second end 24 of the main body 22 is over the free end 47 of the

Befüllungsstutzens 46 and the closure portion 51 slipped until the

Connecting portion 25 comes to rest in the receptacle 49, which is provided more remote than the receptacle 48 of the free end 47 of the filling nozzle 46.

In the method step illustrated in FIG. 4, the closure section 51 is gripped by hand, for example, through the side sleeve 26 of the transfer sleeve 21 and removed from the filling connection 46. The closure portion 51 is pulled in the direction of the arrow 54 in the side sleeve 26 of the transfer sleeve 21. Since the side sleeve 26 has a closed free end 27, no contamination of the environment or the material to be filled 14 can occur in this process. Subsequently, the side sleeve 26 is closed in a region between the outside of the main body 22 of the transfer sleeve 21 and the closure portion 51 located in the side sleeve with a closing element 53.

After the removal of the closure portion 51 and before filling the container 16, the sleeve connection 31 via the free end 47 of

Befüllungsstutzens 46 pushed until the mounting ring 32 of the sleeve connection 31 in the mounting ring receiving 50 comes to rest and thus on the

Filling nozzle 46 abuts (Figure 5). The section 28 of the

Base body 22 of the transfer sleeve 21 between the sleeve connection 31 and the second end 24 of the base body 22 of the transfer sleeve 21 accordion-like folded.

The container with the material to be filled 14 is now opened and the container 16 is filled with this material 14. If the filling process of the container 16 is completed, the container or its dispensing opening is closed again. After filling the container 16, the sleeve connection 31 is pushed in the direction of the free end 47 of the filling nozzle 46 until the

Sleeve connection 31 is no longer applied to the filling nozzle 46 (Figure 6). The transfer sleeve 21 is displaced in the same direction, so that the

Connecting portion 25 comes to rest on the second end 24 of the base body 22 of the transfer sleeve 21 in the lower, the free end 47 of the filling nozzle 46 closer receptacle 48.

The transfer sleeve 21 is connected by means of a first closure element 56 between the sleeve connection 31 and the second end 24 of the main body 22 of the

Transfer sleeve 21 and by means of a second closure element 59 between the sleeve connection 31 and the first end 23 of the main body 22 of the

Transfer sleeve 21 closed. The transfer sleeve 21 is thus closed on both sides of the sleeve connection 21. The closure elements 56 and 59 are each formed as a two-part clip, as set forth in the not yet published Swiss patent application with the application number CH 2173/10. The entire content of this Swiss patent application is hereby incorporated by reference and thus forms an integral part of this patent application.

Subsequently, the first closure element 56 is severed in such a way that a partial closure element 57 or 58 closes the corresponding sections of the transfer sleeve 21 on both sides. Then the second

Closing element 59 is severed in such a way that both sides a closing the corresponding portions of the transfer sleeve 21 partial closure element 60 and 61 remains. Instead of first severing the first closure element 56, first the second closure element 59 and then the first

Closing element 56 are severed. In the illustration according to FIG. 6, the state after the severing of the closure elements 56 and 59 is shown.

The remaining on the filling nozzle 46 part of the transfer sleeve 21 forms a new closure portion 66, which closes the filling nozzle 46 until the arrangement of a further container to be filled 16. The am

Closure portion 66 remaining sub-element 57 of the first

Closure element 56 ensures a tight closure of the filling nozzle 46. The partial element 61 of the second closure element 59 remaining on the closed container 16 ensures a tight closure of the container 16. The remaining on the container 16 portion 29, the first end 23 of the

Base body 22 of the transfer sleeve 21, additionally ensures a tight closure of the container 16th

In the separated middle part 68 of the transfer sleeve 21 befindliches material 14 can not penetrate to the outside, since the middle part 68 at one end by the

Sub-element 58 of the first closure element 56 and at the other end by the sub-element 60 of the second closure element 59 is closed. Before the disposal of the middle part 68, the sub-elements 37 of the fixing element 36 and the sealing element 41 are removed and reused in the next arrangement of a container 16 to be filled. The mounting ring 32, however, is disposed of with the central part 68 of the transfer sleeve 21.

The sleeve connection 31 is pushed by means of a clamping device 121 over the free end 47 of the filling nozzle 46 until the sleeve connection 31 or the mounting ring 32 abuts the filling connection 46. The clamping device 121 is fixed, for example, on the container. By means of this clamping device 121, the sleeve connection 31 is fixed to the filling nozzle 46. An especially suitable for the aforementioned method clamping device 121 is shown in Figures 9 to 10.

The tensioning device 121 comprises a fastening plate 122, a

Guide means 131, one guided by the guide means 131

Receiving plate 141 and in this example four clamping elements 151 for

Bracing the receiving plate 141 on the mounting plate 122nd

The mounting plate 122 is provided with a plurality of mounting holes 123 for the passage of fastening means, not shown here, by means of which the clamping device 121 can be fixed to a container or on a substrate. The mounting plate 122 biases a plane E. From the side 124 of the mounting plate 122 protrude from two guide rods 132, which along with the same displaceable, and on the

Receiving plate 141 fixed guide sleeves 133, the guide device 131st form. At each guide sleeve 133, a clamping screw 134 for temporarily fixing the guide sleeve 133 is provided on the corresponding guide rod 132. By means of the clamping screws 134, the receiving plate 141 in a plurality of positions along the guide rods 132 relative to the

Fixing plate 122 can be positioned and fixed.

From the side 124 of the mounting plate 122 further protrude from four hooks 153, which together with arranged on the receiving plate 141

Clamping levers 152 form the clamping elements 151. From the same side 124 of the mounting plate 122 also projects from a discharge nozzle or a filling nozzle 166, wherein the free end 167 in the direction of

Receiving plate 141 is aligned. The filling nozzle 166 advantageously has the features of the filling nozzle 46 described above.

The receiving plate 141 is aligned parallel to the plane spanned by the mounting plate 122 plane E, relative to the mounting plate 122 slidably and provided with a receptacle 142 for the sleeve connection 31. The receiving plate 141 has an annular configuration in plan view. At two opposite areas are at the ring inside

Inserted recesses 143 provided. Whose size is chosen such that the sleeve connection 31 inclined to the receiving plate 141 of the

Mounting plate 122 facing away from 144 of the receiving plate 141 in the

Space between the receiving plate 141 and the mounting plate 122 can be inserted. Subsequently, the sleeve connection 31 is again brought into an alignment parallel to the receiving plate 141 and placed on the receiving plate 141.

After fixing the second end 24 of the base body 22 of the transfer sleeve 21 to the filling nozzle 166, the receiving plate 141 is moved in the direction of the mounting plate 122 until the hooks of the clamping lever 152 are inserted into the hooks 153. By turning the clamping lever 152, the clamping device 121 is braced and pushed with the receiving plate 141 co-moving sleeve connection 31 via the filling nozzle 166 and secured to this (Figure 1 1).

In the variant shown in FIG. 7 for creating a sleeve connection 71 between the connection region 77 of the container and the base body 82, the transfer sleeve is the one before the slippage of the first end of the base body 82 free end 78 of the terminal portion 77 of the container at least partially folded back. The connection region 77 is thus arranged in a double-layered manner on the outside of the mounting ring 72 in the region of the mounting ring 72.
