This package type can exist before filling-flat and sealed. Thus the sterilization of the chamber of the package is related to the production and by being kept sterile the package can be dispensed to - for example, the filling of the dairy field. It is known that the produced rolls are composed of the interconnected packaging rolls of the above type, which are wound up on a bobbin) and the roller is placed in the filling machine in the filling machine. The coiled material is fed out of Hi:;, the package arrives for removal of the end seal by the = station cold pack-fill station, and arrives for closing the fill pack: 密: 145205.doc -4 - 201028339 The removal of this end seal can be achieved in many different ways. One method of removing the end seal is by using a device that includes a rotating cut-off wheel having a cutting edge. For example, such a device can be found in European Patent No. 1997596. The cutter cooperates against a plane of the wheel. The shaft of the cutting wheel can be slightly inclined to the abutment wheel to obtain a -cut nip' where shearing/cutting occurs for the removal of the terminal (four) port. It has been shown that the removal of the end seals of packages made by this technique can sometimes lead to difficulties in subsequent production stages in which the walls of the filling grooves are separated from each other to allow for the introduction of a true-fill nozzle. This is caused by the fact that the walls of the filling groove tend to stick to the cutting surface in some cases. One of the factors contributing to this phenomenon is the packaging material; the plaque & / plaque is produced in the (iv) surface associated with the removal of the end seal. Another effect that causes these phenomena is due to (iv) a cold weld that is created in the cut surface between the sidewalls of the package. The cold welding is produced as a result of compression of the packaging material associated with the cutting, that is, all of the cutting surfaces of the sides of the package are pressed against each other and form molecular bonds that cause the sides (faces) (4) At the beginning. The term cold welding is used to express that the temperature at which the adhesion occurs is substantially lower than the temperature at which the packaging material melts. An alternative method of removing the end seal is to use a crushing knife having a circumference, one of the peripheral cutting edges being disposed by a rotatably disposed knife relative to a fixed post to form a nip. It is introduced therein for removing the end seal. Even when the end seal is removed in this way, the above problem (i.e., the stain of the packaging material and one of the cold welding of the surface of the cut 145205.doc 201028339) may still occur. Another alternative (method) is the use of a bayonet blade type - fixed knife. The removal of the end seal is thereby accomplished by the fact that there is substantially no cold welding of the (four) wall of the pure groove of the (4) surface of the packaging material. Another problem that arises in this respect is the wear resistance of the knife. This same point is always caused by the cut so that the knife is quickly worn and needs to be replaced, and the beans cause frequent production interruptions. 〃

The cut-off trains are arranged in an overlapping arrangement with respect to the vehicle. A gap is disposed between the cutting wheel and the offset. If the device is to be used for removal - one of the foldable packages - the end seal will then be removed by a similar or a sharp cut, instead of a shear-like method, This method of similarity (4) or milling, will obviously cause the formation of dust. There is thus a need to provide a reliable and simple method for removing one of the end seals of a foldable package. This method also allows for subsequent easy and reliable separation of the walls of the open fill groove. SUMMARY OF THE INVENTION In view of the above, it is an object of the present invention to provide a device for reliably and simply removing one of the end seals of a foldable package. Another object of the present invention is to reliably and simply remove the foldable one of the end seals of the stacked package, which also allows for the subsequent simple and reliable separation of the open fill groove. Waiting for the wall. In order to accomplish the above designations and other non-designated 145205.doc -6 - 201028339 objects that will appear in the following description, the present invention relates to a device as in the prior art. Embodiments of the device will appear in the technical solutions 2 to 14. In accordance with a first aspect of the present invention, the present invention is directed to an apparatus for an end seal of a removable-foldable package having an end closure closing a groove, the groove being by the two opposite sides of the package The side walls are delimited. The device includes a cutting wheel (which has a circumferential configuration, pointed teeth) and an abutment wheel. The teeth of the cutting wheel collectively define a cutting wheel cutter that extends continuously in a circle. The breaker is further rotatably disposed about a first axis of rotation. The conviction wheel is also rotatably disposed about a second axis of rotation. The second axis of rotation is parallel to the first axis of rotation. In addition, the cutting wheel has an L-long extending, peripheral cutting wheel surface that partially defines the cutting wheel. The cutting wheel has a controlled extending abutment wheel surface facing the first cutting wheel surface. . The cutting wheel surface of the cutting wheel and the abutment surface of the abutment wheel are provided with an overlapping contact for the formation of a cutting nip. This is provided as a π-load & which allows for a reliable and simple removal of a foldable and 51-package-end closure. The removal of the end seal caused by the skirt also allows for the subsequent removal of the tip seal of the open cutter groove by simply and reliably separating the open fill groove. Behavioral pulsation cut. In the test, it has been shown that the removal of the end seal by the above-mentioned device can prevent the stain of the packaging material, and the cold of the wall of the filling groove of the cutting 矣 & a & i _ In addition, it has also been shown that when the end seal is removed, a smaller air pocket is formed between the opposite side walls of the package when the device according to the invention is removed. 'The teeth are joined to the package. These air pockets allow air to simply penetrate between the opposite side walls of the package when the two opposing side walls of the 145205.doc 201028339 package are separated. When the package is The fact that the air can simply flow into the package when the side walls are separated means that the separation of the side walls is very easy to achieve. This is accompanied by the fact that the packaging material is not smeared or does not stick together in the lateral portions of the side walls of the package. Allowing the groove of the package to be simply and reliably opened after the end seal is removed. Each of the teeth of the cutting wheel can have an angled tip at a right angle to the first axis of rotation Flat If the package (with its end seal to be removed) is fed into the cutting nip substantially parallel to the plane of the first and second axes of rotation, then a full angle is allowed between the package and the tip Thus, when the end seal is removed, a minimum contact surface is obtained between the package and the tip. The tip can be located at a maximum distance from one of the centers of rotation of the cutting wheel. At least one of the breaking wheels may be axially biased against the other of the abutting wheel and the S-shaped cutting wheel. Thus, a better cutting effect/shearing effect can be achieved in the nip 45. The arrangement can be completed by means of a spring for causing one of the first or second shafts to be pressed against the surface of the cutting wheel of the cutting wheel and the abutment wheel surface of the abutting wheel Axial displacement occurs in the direction of the same. It should be understood that the abutment wheel can be biased against the cutting wheel, or the cutting wheel can be biased against the abutment wheel. Alternatively, the abutment wheel can be biased Abutting the cutting wheel, the cutting wheel can be biased against the abutting wheel. And comprising a circumferentially extending abutting wheel cutting edge, the abutting wheel surface portion defining the abutting wheel cutting edge. The abutting wheel also has a 145205.doc 201028339 cutting edge, meaning - better boundary ^ The cutting gap can be obtained. The device can further include a driving member configured to rotate the at least one of the abutting wheel and the cutting wheel. The driving member can be rotated from the m And rotating the (four) wheel at the same time. The driving member can be configured to rotate the (four) broken wheel and the abutting wheel in opposite directions. Thus, the cutting wheel and the abutting wheel move direction (the Φ two The wheel overlaps in this direction) substantially in the same direction of movement as the package being fed into the device, the end seal of which is to be removed. The cutting wheel surface and the abutment wheel surface may be complementary to allow for the overlapping contact. In particular, the cutting wheel surface and the abutment wheel surface may be flat. The cutting wheel and the abutment wheel can thus be rotated simply. The cutting wheel cutter can have a number between 10 and 60. The angle of the cutting edge within the range. The abutment wheel cutting edge can have a range of 20 to 90. The cutting edge angle in the range is 10 degrees. When the cutting wheel cutter and the abutting wheel cutting edge have a sharp cutting edge angle, a well defined nip is obtained, wherein the cutting/shearing is achieved, and thereby the shearing effect is improved. The sharper the cutter, the better the nip obtained, which means that a better shearing effect can be obtained. However, the sharpness must weigh the life of the various cutting edges. The sharper the cutter, the shorter the service life. The cutting wheel has a cross-sectional surface in the shape of a truncated cone. The cutting wheel may have a first cutting wheel main surface and a second cutting wheel main 145205.doc 201028339 surface (which is opposite to the first cutting wheel main surface), and - a radially outer cutting wheel side And connecting the main surface of the first cutting wheel to the main surface of the second cutting wheel. The side of the cutting wheel can be slotted. The teeth of the cutting wheel can be simply formed by the milling of the grooves on the side of the cutting wheel. The abutment wheel has a cross section that is shaped like a cone. [Embodiment] The embodiments of the present invention will now be described with reference to the illustrative purposes of the drawings. 1 illustrates an example of a method for producing a foldable package, which is not limiting for the present invention. The package is produced by a -folded packaging web 2 comprising two opposing side wall forming portions & η and a folded bottom wall forming portion 3 disposed therebetween. The packaging web 2 is preferably produced from a flexible, laminated packaging material. The packaging material may comprise a core layer of a polyolefin material. The core layer may further comprise a mineral material fill which may advantageously consist of chalk (calcium carbonate). For the formation of a package 1, the two side wall forming portions 2a, the holes and the bottom forming portion 3 are gathered together in a tool. The tool joins the portions 2a' 2b, 3 along a connecting portion 4 for delimiting a chamber 5. For example, the tool 1 can connect the connecting portions 4 by means of heat, pressure, ultrasonic waves or a combination thereof. The finished package 1 has a sealed chamber 5. The franchise packs 1 are connected to each other. Thus, a long coil of packaging is formed. For example, the remaining material that does not form part of the package can be removed in a roller press (not shown) of 145205.doc -10 - 201028339. The elongate web of package 1 can then be rolled onto a spool to form a newspaper wheel containing interconnected empty packages! One of the coils. This comparison wheel can therefore be assigned to a filling plant for use in a filling machine. One of the above types of packages 1 is illustrated in FIG. The package includes two opposing side walls 6a, 6b and a bottom wall 7 which are folded into a double wall shape. The side walls 6a, ❿ of the package collectively define a groove 8 which is closed in the illustrated unfilled state of the package φ. By the removal of one of the end seals 9 of the package i, the groove 8 is opened' by which the chamber 5 of the package can be connected to the outside via the groove 8 to allow the package to be filled. By way of example 5, the groove 8 is configured to be reclosed, for example by heat sealing, after filling. The present invention relates to a device 12 for removing an end seal 9 of a foldable package and an embodiment of the invention of the invention will be described below. Referring to Figures 3 through 6, an embodiment of a device 12 for removing the end closure 9 of a foldable pack® 1 is shown in accordance with the present invention. The groove 8° bounded by the side walls 6a, 6b - the device 12 includes a cutting wheel 20 and an abutment wheel 30. Referring in particular to Fig. 5, in the illustrated embodiment, the cutting wheel 2 has a cross section in the shape of a truncated cone. Referring particularly to Figure 5, in the illustrated embodiment, the abutment wheel 3〇 also has a cross section in the shape of a truncated cone. The cutting wheel 2 is supported by a second jaw and is configured to rotate symmetrically about a first axis of rotation 26. . The abutment wheel 30 is supported by a first rod and is configured to rotate symmetrically about a second rotation 145205.doc 201028339 axis 36. The second rotating shaft 36 is parallel to the first rotating shaft 26. In the illustrated embodiment, the first and second rods extend along the first and second axes of rotation 26, 36, respectively. The cutting wheel 20 has a cutting wheel cutting edge 22 that extends continuously in a circle. The cutting wheel 20 further has a radially extending, peripheral and circumferential cutting wheel surface 24. The cutting wheel surface 24 partially defines the cutting wheel cutting edge 22. The abutment wheel 30 has a radially extending 'perimeter and circumferential abutment wheel surface 34. The abutment wheel surface 34 faces the first cutting wheel surface 24. Additionally, the cutting wheel surface 24 of the cutting wheel 20 and the abutment wheel surface 34 of the abutment wheel 3 are configured with an overlapping contact for the formation of a cutting/shearing nip 45. To allow for the overlapping contact, the cutting wheel surface 24 and the abutment wheel surface 34 are complementary. Advantageously, the cutting wheel surface 24 and the abutment wheel surface are "flat." In the embodiment shown in Figures 3 to 6, the cutting wheel 20 is disposed below the abutment wheel 30. However, it should be understood The cutting wheel 2〇 and the abutting wheel 3〇 can be changed in position. In order to complete the necessary cutting effect/shearing effect on the nip 45, the cutting wheel surface 24 of the cutting wheel 2 and the abutment The abutment wheel surface 34 of the wheel 30 is configured with load overlapping contacts, which means that the wheels are pressed against each other by at least one of the abutment wheel 30 and the cutting wheel 20 relative thereto. The axial offset is accomplished against the other of the wheel 30 and the cutting wheel 2 . This biasing can be accomplished by means of a spring that seeks the first 145205.doc • 12- 201028339 or the second One of the rods is axially displaced in a direction in which one of the cutting wheel surface 24 of the cutting wheel 20 and the abutting wheel 3's abutting wheel surface 34 are pressed against each other. It should be understood that the abutting wheel 3〇 Can be biased relative to the cutting wheel 2 or the cutting wheel 20 can be biased relative to the abutment wheel 30. Alternatively, the abutting wheel 30 can be phased The cutting wheel 2 is biased while the cutting wheel 2 is biased relative to the abutment wheel 30. However, if the cutting wheel 20 and the abutment wheel 30 are fixed Preferably, the vertical direction is obtained, whereby a cutting height that is better than φ is obtained. Further, the cutting wheel 2 has a circumferential arrangement and pointed teeth 21. The teeth are common to the circumference Continuously extending cutting wheel cutters π. Each of the teeth 21 has an angled tip 23 in a plane at right angles to the first axis of rotation 26. This is illustrated in Figures 3-6. In an embodiment, the tip is located at a maximum possible distance from the center of rotation of the cutting wheel 20. In the illustrated embodiment shown in Figures 3 to 6, the continuous extension of the cutting rim & 22% of the waveform. See below, other types of configurations of the teeth 21 and the cutting wheel cutting (4) are also possible. As described above, the cutting wheel 20 has a cross section of a truncated cone shape and thus Having a first cutting wheel main surface 27 and a second cutting wheel main surface 28 (which is opposite to the first cutting wheel main surface 27) And a radially outer cutting wheel side 29 that connects the first cutting wheel main surface 27 to the second cutting wheel main surface 28. As in the illustrated embodiment of Figures 3-6, The cutting wheel side 29 can be slotted. In the illustrated embodiment, the recess can be formed by the method of producing the teeth 21 of the cutting wheel 20. ciscut 145205.doc • 13- 201028339 The teeth 21 of the broken wheel 20 can be simply formed by the milling of the grooves on the side of the cutting wheel. The "Hair cutting wheel cutting edge 22" is defined by the first cutting wheel main surface 27 and the cutting wheel side surface 29. The cutting wheel cutting edge 22 has a sharp cutting edge angle, i.e., the cutting edge angle is less than 9 〇. . Advantageously, the cutting wheel cutter 22 has a cutting edge angle of less than 450. In the embodiment shown in FIGS. 3 to 6, the abutment wheel 3 includes a first abutment wheel main surface 37 and a second abutment wheel main surface 38 (which is opposite to the first abutment wheel main surface) 37 opposite), and a radially outer abutment wheel side 39 that connects the first abutment wheel major surface 37 to the second abutment wheel major surface 38. The abutment wheel side 39 is inclined. The bevel defines a circumferentially extending abutment wheel cutting edge 32. The abutment wheel cutter 32 is sharp. Advantageously, the abutment wheel cutting edge 32 has an angle of 20-90. The angle within the range. Since both the cutting wheel 20 and the abutment wheel 3 have a cutting edge 22, 32 with a sharp cutting edge angle, a well defined nip 45 is obtained (where the cutting/shearing occurs) and Thereby the shearing effect is improved. The sharper the cutting edges 22, 32, the better the nip 45 obtained can be better defined and the better the shearing effect obtained. However, the sharpness must weigh the useful life of the individual cutting edges 22,32. The sharper the cutting edge, the shorter the service life. For example, the service life of the abutment wheel cutting edge 32 can be extended by the above-described bevel angle, which means that the cutting edge angle is sharper. Since the abutment wheel 30 includes the bevel, it is possible to obtain one of a larger cutting edge angle against the wheel cutting edge 32, the cutting edge angle being greater than the cutting edge angle of the abutting wheel side 39. 145205.doc •14· 201028339 Furthermore, the device 12 includes a drive member 40 that is configured for rotation of the abutment wheel 30 and the cutting wheel 20. The drive member 40 can be a motor, particularly an electric motor. The drive member 40 is configured to rotate the cutting wheel 2 about the first axis of rotation 26 and to rotate the abutment wheel 30 about the second axis of rotation 36. The drive member 40 can rotate both the cutting wheel 20 and the abutment wheel 30 because its rotating shafts 26, 36 are coupled together by a first and a second large tooth 25, 35. However, it should be understood that the abutment wheels 3 〇 and φ the cutting wheels 20 can be rotated by their respective drive members. The driving member 40 is configured to rotate the cutting wheel 20 and the abutting wheel 30 in opposite directions. The moving direction of the cutting wheel 20 and the abutting wheel 30 (the two wheels overlap in the direction) The movement direction of the package 1 to be removed from the end seal 9 is substantially the same. This feed of the packaging web can be effected intermittently, which causes acceleration and deceleration of the same web so that the feed rate is not constant. Alternatively, the packaging web can be continuously fed at a constant feed rate. φ The circumferential speed of the cutting wheel and the abutment wheel should be slightly higher or at least equal to the maximum feed speed. In the case of continuous feed at a constant speed, it is important that the peripheral speed is slightly higher or at least equal to the constant feed rate. The circumferential speed of the cutting wheel 20 and the abutment wheel 30 will thus be slightly higher than the maximum feed rate of the packaging web. As a non-limiting example, the peripheral speed of the cutting wheel 20 and the abutment wheel 30 is 5-10% higher than the feed rate of the packaging web. This is because if the peripheral speed of the cutting wheel 20 and the abutment wheel 30 is equal to or lower than the speed at which the packaging web is fed, the nip 45 produces a resistance. This means that, subsequently, the position of the shear in the vertical direction of the package is uncontrolled. In order to obtain a vertically controllable shear cut, the peripheral speed of the cutting wheel 2 and the abutment wheel 3 must be slightly higher or at least equal to the maximum feed speed of the packaging web. A typical feed speed of one of the packaging rolls is _2 5_2 m/s. The end seal 9 is to be removed from the package 1 to be fed into a cutting nip 45 substantially parallel to the plane of the first and second axes of rotation 26,36. As a non-limiting example, it can be provided that the abutment wheel 3 and the cutting wheel 2 can be constructed to have a diameter in the range of 40 to 80 mm. A method of selecting the diameter of the wheels 20, 30 is used for the diameter to be selected such that the cutting wheel 20 and the peripheral speed of the abutment wheel 30 (which is given by the drive member 40) The rotational speed) slightly exceeds the feeding speed of the package 1 to which the end seal 9 is to be removed. According to a practical embodiment, the cutting wheel 2 and the abutment wheel 30 have been constructed to have a diameter of 60 mm. Furthermore, as a non-limiting example, it is also stipulated that the abutment wheel 3 and the cutting wheel 20 can be constructed to have a thickness in the range of 2 to 8 mrn. According to a practical embodiment, the cutting wheel 20 and the abutment wheel 3 have been constructed to have a thickness of 4 mm. As a non-limiting example, it is also possible to specify that the number of teeth 21 in each unit length of the cutting wheel 2 is between 0.1 and 2 teeth per millimeter. In a practical embodiment, the cutting wheel has been constructed to have 72 teeth ', i.e., about 4 teeth per mm, along the circumference of the wheel having a diameter of -6 mm. Since the peripheral cutting edge 22 of the cutting wheel 20 has a sharpened tooth, a snapping pulsation shear can be achieved at the removal of the end seal 9. 145205.doc •16- 201028339 In the test, it has been shown that the removal of the end closure 9 of the package made by the above defined device 12 prevents staining of the packaging material and minimizes the filling of the cut surface. Cold welding of the wall. In addition, referring to Fig. 7, it has also been shown that when the field end seal 9 is removed by the device 12 according to the present invention, the small air pockets 50 are formed on the two opposite side walls of the package 1; between. These air pockets 50 are formed in relation to the gear teeth η engaged with the package magazine. The air pockets 50 allow air to simply penetrate between the opposite side walls of the package when the two opposing side walls of the package are separated from each other. One method of separating the side walls 6a of the package 1 is to provide a jaw member that first grasps the side walls of the package by means of a clamp arm having a suction cup and then the jaw arms are separated The side walls 6a, 6b for separating the package cassettes. Due to the air pockets 50, the fact that air can simply flow into the package j when the side walls 6a, 6b of the package 1 are separated means that the side walls This separation of 6a, 6b is easier to achieve. This, together with the fact that the packaging material in the portion transverse to the side walls 6a, 6b of the package 1 is subjected to Φ a reduced stain and cold welding allows the package 1 to be removed after the end closure 9 has been removed. The groove 8 is opened simply and reliably. In the illustrative embodiment described above, the apparatus 12 has been described as having a cutting wheel 20' having a circumferential configuration, pointed teeth 21 that collectively define a circumferentially extending wavy cutting wheel cutting Knife 22. As mentioned above, other configurations of the teeth 21 and the cutting wheel cutting edge 22 are also possible. An example of an alternative configuration of one of the teeth 21 and a cutting wheel cutter 22 can be seen in Figure 8a. In this case, each of the teeth 21 has two mutually opposite angled tips 23a, 23b' which are in a plane at a right angle to the first axis of rotation 26, 145205.doc -17 - 201028339. The tips 23a, 23b may have a curvature that is directed to the center of the cutting wheel 2''. Other examples of possible embodiments of the teeth 21 are wheels #21 having a shark fin shape, an angular shape, a square shape, and the like. Some possible embodiments of the teeth 21 are illustrated in Figures 6, 8a-f. It will thus be appreciated that the invention is not limited to the described embodiments. Many modifications and variations are possible, so that the scope of the invention is defined only by the scope of the claims.
