[0002] More specifically, the method and apparatus according to the present invention comprises a method for removing an object produced in a mold from the mold. Transporting objects by moving them between the This makes it possible to do so.

[0003] The method and device according to the invention are adapted to remove objects having protruding edge bands, e.g. in the form of flanges. and / or an object bounded by flared side walls, i.e., gradually toward the opening of the object It is particularly suitable for transporting objects with diverging side walls. Examples of these objects include: Powdered or granular substances, such as coffee, that are arranged to prepare beverages or other edible fluids or capsules that have been subjected to a blow molding or stretch blow molding process. A specific type intended to be used to form a container or receptacle such as a cup, jar, or bowl. Examples of preforms include

[0004] However, the method and apparatus according to the invention can be used to make other types of tyres, e.g. caps. It can also transport objects of different sizes. [Background technology]

[0005] Apparatuses are known whose task it is to produce objects by compression moulding doses of polymeric material. The prior art apparatus includes a number of dies. Each die has a male part with a punch and a cavity. The molds are located in the peripheral area of ​​a molding carousel that is rotatable about a vertical axis. Also, the prior art device includes a transport carousel that provides a plurality of transport elements, each of which The material is transported away from the forming carousel, e.g., to an outfeed conveyor. Therefore, it is suitable for receiving the object that has just been molded and extracted from the mold.

[0006] Each transfer element has a base capable of receiving an object to be transferred and two side walls separating the base. A fixed guide may be provided, and a C-shaped conveying portion may be provided having a protrusion. The fixed guides work in conjunction with the transfer elements to continue guiding the objects during transport towards the outgoing conveyor. In particular, while the objects are being conveyed towards the outfeed conveyor, each object is Each object is in contact with a transfer element. In the lateral regions of the guide there is further contact.

[0007] The objects are usually delivered to the transfer elements from the top downwards because they are formed the part of the mold that is in contact with the object being moved away from the support of the transfer device; The object is then released onto the support disk. Thus, the transfer element is inserted between the conveying portion and the fixed guide, and then the transfer element is inserted into the delivery conveyor. will be transported towards

[0008] A transport carousel of the above type may be used to transport objects, as occurs in the case of caps. provides superior performance when the axial direction is bounded by a generally cylindrical lateral surface. The object being conveyed may have a protruding edge band, e.g., in the form of a flange protruding from the side wall of the object. or when the object being conveyed is a capsule of coffee or a similar product. The sidewall may have a truncated cone-shaped or more general sidewall that widens toward the end. In some cases, the object to be conveyed may be moved between the transport element and / or between the object to be conveyed and a fixed guide. This can result in mechanical interference between the object and the transport device. , objects cannot be transported accurately, and in the worst case scenario, this can lead to jams that shut down the machine. There is a drawback to this.

[0009] Examples of prior art devices are disclosed in US Pat. No. 5,399,623 and US Pat. No. 5,499,623. [Prior art documents] [Patent documents]

[0010] [Patent Document 1] US Patent Application Publication No. 2012 / 171319 [Patent Document 2] US Patent Application Publication No. 2012 / 201920 Summary of the Invention [Problem to be solved by the invention]

[0011] The object of the present invention is to provide a method for removing objects which must be moved away from a molding device, in particular by compression molding. The object is to improve the method and apparatus for transporting manufactured objects.

[0012] A further object is to provide a method and apparatus for moving an object away from a mold, whereby the object The object of the present invention is to reduce the risk of the object being inaccurately positioned when it is released from the mold. .

[0013] Another object is to provide a method for manufacturing an object having a protruding edge band, such as an object having a flange-like shape. Moreover, a method and apparatus that can be used to successfully move the mold away from the mold is provided. This is what we should do.

[0014] Another object is to provide an object having a sidewall that gradually widens toward the end of the object, e.g., a frusto-conical sidewall. Method and apparatus that can be used to successfully move even a body away from a mold - Patent 7326633 The purpose of this project is to provide [Means for solving the problem]

[0015] In a first aspect of the present invention, a method for transporting a concave object having a sidewall away from a die includes: The method includes the following steps. Providing a transport element and a guide element movable along a path. While the transfer element is spaced from the object, the object is extracted from the mold, and the transfer element and the guide element are Releasing the object in the clamped position onto the support surface. The transfer element is displaced towards the object so that the transfer element contacts the side wall. A step in which a transfer element moves along a portion of the path to convey the object toward a delivery position. Top.

[0016] According to a first aspect of the invention, between the object and the transport element and / or between the object and the guide element The object extracted from the mold can be conveyed toward the delivery position without unnecessary interference from the The interference prevents the object from being accurately positioned between the transport element and the guide element, thereby It may be difficult to transport the object towards the delivery position. When the transport element is located between the transport element and the object, the transport element is more stable than the prior art. At a distance from the inductive element such that a gap exists between the object and / or between the object and the inductive element. In practice, the actuator is in a more recessed position and therefore does not interfere with the transport and / or guidance elements. The object can be positioned between the transport element and the guide element without the need for a guide. This reduces the risk of the object being inaccurately positioned between the transport element and the guide element.

[0017] In one embodiment, during the step of extracting the object from the mold, the extraction element couples the object with the transfer element. The object is brought into contact with the support surface by passing it between the guide elements.

[0018] In addition to transferring the object from the mold, the extraction element also transfers the object away from the mold. The extraction element is attached to the object from the moment the object contacts the support surface. The object's position is controlled while it moves toward the support surface, thereby allowing the object to fall freely onto the support surface. Free fall can adversely affect the positioning accuracy of an object on a supporting surface. There is.

[0019] In one embodiment, the transfer element holds the object while the extraction element moves away from the support surface.

[0020] The transfer element therefore performs further functions in addition to transporting the object towards the transfer position. That is, the transfer element aids in accurately separating the object from the extraction element.

[0021] In one embodiment, the article includes a protruding edge band that protrudes outwardly from one end of the side wall.

[0022] During the step of displacing the transfer element toward the object, a portion of the protruding edge band is provided on the transfer element. It is received in a concave band.

[0023] In this way, the transfer element can abut the side wall of the object without interfering with the protruding edge band. This allows the side walls of the object to be used to center the object relative to the transfer element. This makes it possible to improve the accuracy of object positioning.

[0024] In one embodiment, the transfer element acts on the protruding edge band to hold the object and to move the object away from the support surface. Prevent movement between the

[0025] This is an effective way to ensure that the object is detached from the extraction element.

[0026] In one embodiment, the object is directed to the delivery position by contacting a sidewall of the object with a guide element. The material continues to be guided between the transfer element and the guide element while being transported by the transport element.

[0027] This prevents unwanted movement of the object.

[0028] In one embodiment, a portion of the protruding edge band is received in a recess provided in the guide element.

[0029] This may further aid in detaching the object from the extraction element.

[0030] In a second aspect of the present invention there is provided an apparatus comprising: At least one mold for forming the object. At least one transfer element movable along a path to move the object away from the mold. - Works in conjunction with the transfer element to continue guiding the object as it moves away from the mold Inducing elements intended for. a positioning device for positioning the transfer element at a variable distance along the path from the guide element; Thus, when an object is received between the transport element and the guide element, the transport element is separated from the object. and directing the transport element toward the guide element so that the transport element contacts the side wall of the object. The positioning device is further configured to move the positioning device by

[0031] The apparatus according to the second aspect of the invention is described above with reference to the method according to the first aspect of the invention. This makes it possible to obtain the advantages described above. [Brief description of the drawings]

The intermediate support 21 is arranged so that the transfer element 19 is supported by the support disk 17 beforehand. While displacing the object 2 stationary on the conveyor 20 toward the outgoing conveyor 20, the object 2 is temporarily Suitable for support.

[0052] Each transfer element 19 conveys the object 2 from the mold 9 towards the outfeed conveyor 20. The conveying portion 22 may be C-shaped, The base 23 is capable of receiving the object 2. The base 23 is supported by two side projections 24. So it is separated.

[0053] Each transfer element 19 also has an extension portion 25 that projects from the conveying portion 22 toward the axis Z. The extension portion 25 may be disposed generally radially with respect to the axis Z.

[0054] The transfer element 19 is located above the support disk 17. As shown in FIG. are spaced apart from the support disk 17 at least near the respective conveying portions 22.

[0055] The device 1 further comprises a guiding element 26. The guiding element 26 is arranged to guide the object 2 by the transport element 19. The object 2, in particular the object 3, is guided while being conveyed towards the outfeed conveyor 20. The guide element 26 is adapted to interact with the side wall 3 of the guide member 2. The guide element 26 may be arch-shaped. , on the outside of the conveying section 22, i.e., at the position furthest from the axis Z with respect to the conveying section 22 .

[0056] The inductive element 26 is mounted in a fixed position on the device 1 .

[0057] The transport device 15 further comprises a positioning device. The positioning device is adapted to move the transport element 19 around the axis Z. Depending on the angular position of the positioning device, the transfer element 19 is positioned at a variable distance from the axis Z. can be provided with a cam element 27, which is arranged at a fixed position on the device 1. In the embodiment, the cam element 27 is located above the support disk 17 and the transfer element 19. 7 has a cam track 28. The cam track 28 extends along a center line LC shown in FIG. The center line LC is a closed loop line extending around the axis Z. The points of the center line LC are different from the axis Z. It's in the distance.

[0058] The center line LC lies in a plane that is transverse to, and in particular perpendicular to, the axis Z.

[0059] The cam element 27 shown in FIG. 3 is not identical to the cam element 27 shown in FIG. They differ in that the shape of the center line LC is slightly different, but they operate according to the same principle.

[0060] The cam track 28 may be shaped like a groove. In the illustrated example, as shown in FIG. The cam track 28 faces downwards and faces the transfer element 19 .

[0061] The positioning device is arranged to engage the cam track 28 for each transport element 19. Each cam follower 29 is freely rotatable about an axis parallel to axis Z. The cam track 28 may be shaped like a roller and adapted to be received within the cam track 28. Each cam follower 29 is mounted on a corresponding transfer element 19, e.g. On the upper surface, i.e. on the surface of the transfer element 19 located opposite the support disk 17. This can be done.

[0062] The transfer element 19 is supported by the support disk 17 so as to be slidable relative to the support disk 17. and adapted to move towards axis Z or, alternatively, away from axis Z. In particular, the transfer elements 19 are arranged in such a way that they are aligned in the respective radial directions with respect to the support disk 17. In order to allow the transfer element 19 to slide on the support disk 17, a sliding guide is provided. The sliding guide 30 may be shaped like a groove, for example. 3 and 4. The transfer element 19 engages with a corresponding projection therein.

[0063] Each transport element 19 is movable along a closed path P shown in FIG. is the path of the center point.

[0064] Each of the transfer elements 19 includes a concave band 34 as shown in FIGS. 4-7, and is adapted to move the object 2 when the object 2 is resting on the support surface 18. The recessed band 34 is positioned to receive a portion of the protruding edge band 5 when the support disk 1 is in the 7, and in the illustrated example is formed on the underside of the transport element 19. The concave band 34 supports the support disk 17 by means of a stop surface 36 transverse to the axis Z. The stop surface 36 is, for example, a flat surface that is perpendicular to the axis Z. It can be a surface.

[0065] The guide element 26 is defined in plan view by an inner contour which may have a lead-in extension 38. Along the lead-in stretch 38, the distance between the guide element 26 and the axis Z gradually decreases. The lead-in extension 38 allows the object 2 to gradually begin to interact with the guide element 26. Downstream of the inlet extension 38, the inner contour of the guide element 26 substantially copies the path P of the transport element 19. , and is offset by a substantially constant amount relative to the path P.

[0066] A depression 35 is provided on the guide element 26. The depression 35 may be, for example, a step. shaped and diametrically opposite the portion of the protruding edge band 5 that is received within the recessed band 34. The recess 35 is disposed to receive a further portion of the protruding edge band 5. On the surface of the guide element 26 facing the support disk 17, i.e., on the underside of the guide element 26 It is being done.

[0067] The recess 35 is bounded by an abutment surface 37 and is located transversely to the axis Z. That is, it faces the support disk 17. The abutment surface 37 may be flat, for example, It can be positioned perpendicular to the

[0068] During operation, the central body 16 and, with it, the support disk 17 rotate continuously about the axis Z. The transfer element 19 supported by the support disk 17 also rotates about the axis Z. A cam follower 29 associated with the cam element 27 moves along the cam track 28 of the cam element 27. The distance from axis Z of each cam follower 29 as it moves along cam track 28 Therefore, the conveying element 19 guided by the sliding guide 30 is moved in a direction parallel to the support disk 17, e.g. , and moves radially relative to the

[0069] In this way, each transport element 19 moves along a closed path P, which is shown diagrammatically in FIG.

[0070] While the transfer element moves along the closed path P, the die 9 moves along a trajectory PS. The mold is heated to a temperature sufficient to allow the object 2 to be handled without being damaged. Once cooled within 9, the male and female parts 10 and 11 can be moved relative to each other, In the example shown in FIG. 1, the male part 10 is moved downward so that the mold 9 is at the maximum opening position PA. It is now possible to extract the object 2 from the mold 9.

[0071] In the illustrated example, the object 2 remains associated with the female part 11 after the mold 9 is opened as shown in FIG. There is even one.

[0072] The female part 11 includes an annular forming element 31. The annular forming element 31 extends about a forming axis S, It is suitable for shaping the outside of the side wall 3 of the object 2. The female part 11 further comprises an extraction element 32. The extraction elements 32 are delimited by forming surfaces 33 and form the lateral walls 4 of the object 2 from the outside. The extraction element 32 is adapted to rotate along the forming axis S between the forming position PF and the extraction position shown in FIG. The extraction element 32 is movable along the support surface 18 so as to bring the object 2 into contact with the support surface 18. At the forming position PF, the extraction element 32 separates from the annular forming element 31 and the male part 11. 10 to form the object 2. At the same time, the extraction element 32 moves along the molding axis S towards the male part 10. When this happens The extraction element 32 presses against the lateral wall 4 of the object 2, which causes the object 2 to be pulled out of the annular forming element 31. A force is applied to object 2 that enables it to be detached from the object.

[0073] When the mold 9 is at the maximum opening position PA, a transport device 13 is provided between the male part 10 and the female part 11. The transport element 14 of the transport device 15 and the transport element 19 of the transport device 15 are inserted. As shown in FIG. 4, the transfer element 19 is located at a higher position than the step 14. The distance D1 is greater than the maximum lateral dimension Dmax of the object 2. In the particular example shown, the maximum lateral dimension Dmax is the outer diameter of the protruding edge band 5. On the other hand, the distance D1 is on the central plane of the transfer element 19, i.e., on the plane passing through the center of the base portion 23. It will be taken.

[0074] Here, the extraction element 32, to which the object 2 is firmly fixed, is aligned along the molding axis S with the male 10, detaching the object 2 from the annular forming element 31. At the same time, the cam element 27 and cam follower 29 move the transfer element 19 towards the guide element 26 .

[0075] FIG. 5 shows the moment when the extraction element 32 is moving towards the male part 10 and has already reached the object 2. The object 2 is separated from the annular forming element 31 and sandwiched between the transport element 19 and the guide element 26. The object 2 is still firmly fixed to the extraction element 32. Here, the transport element 19 is at a distance D2 from the guide element 26. The distance D2 is smaller than the distance D1. However, it is still larger than the maximum lateral dimension Dmax of the object 2. 2, the protruding edge band 5 of the object 2 is prevented from interfering with the transport element 19 and / or the guide element 26. , the object 2 can be caused to pass between the transport element 19 and the guide element 26 .

[0076] The extraction element 32 is directed toward the support surface 18 until the protruding edge band 5 of the object 2 rests on the support surface 18. At the same time, the transfer element 19 moves toward the object 2 as shown in FIG. 3, the protruding edge band 5 of the object 2 is at least partially inside the concave band 34 of the transport element 19. Here, the stop surface 36 of the transport element 19 is at least partially received by the projection 34 of the object 2 . It is located above the chime band 5.

[0077] During the rotation of the central body 16 about the axis Z, the positioning device moves the transfer element 19 towards the object 2. 3, the transport element 19 comes into contact with the side wall 3 of the object 2 .

[0078] When the object 2 approaches the end of the lead-in extension 38 of the guide element 26, the protrusions facing the guide element 26 A portion of the chime strip 5 is received in the recess 35 .

[0079] Furthermore, due to the shape of the guide element 26 , the side wall 3 of the object 2 comes into contact with the guide element 26 .

[0080] After positioning the object 2 on the support surface 18, the extraction element 32 moves back, i.e. along the forming axis. The transfer element 19 and / or the guide element 2 move along the line S towards the annular forming element 31. 6 engages the object 2 and holds it close to the support surface 18. As a result, the object 2 is held in place by the extraction The stop surface 36 and / or the support disk 17 are separated from the element 32 and remain stationary on the support disk 17. The abutment surface 37 blocks the protruding edge band 5 of the object 2, thereby preventing the object 2 from contacting the extraction element 32. Together they prevent it from moving back towards the annular forming element 31 .

[0081] In this way the object 2 is released onto the support surface 18 .

[0082] When the side wall 3 of the object 2 contacts both the transport element 19 and the guide element 26, as shown in FIG. In this configuration, in particular, the transfer element 19 is attached to a part of the side wall 3 of the object 2 . while the guide element 26 is diametrically opposite to the portion of the side wall 3 with which the transport element 19 contacts. , contacting a further portion of the side wall 3 of the object 2 .

[0083] The object 2 is in an upside-down configuration, i.e. the protruding edge strip 5 faces downwards and the lateral wall 4 faces upwards. This configuration is the configuration in which the object 2 is formed in the mold 9. The recess of the object 2 bounded by the side wall 3 and the transverse wall 4 faces the support surface 18. do.

[0084] The recessed band 34 accommodates the protruding edge band 5, so that the transfer element 19 abuts against the side wall 3 of the object 2. 3. The transport element 19 is therefore in contact with the object 2 and ensures that it does not abut against the protruding edge band 5. The side walls 3 are used to transport the objects 2 towards the outfeed conveyor 20, which in turn transports the objects 2 towards the transfer element 19 This ensures greater accuracy and reliability during the transportation of the object 2.

[0085] Furthermore, by accommodating a portion of the protruding edge band 5 opposite the transfer element 19 in the recess 35, Thus, downstream of the gripping position PP, the guide element 26 interacts with the object 2 at the side wall 3 of the object 2. This ensures that the transfer element 19 working in conjunction with the guide element 26 It is possible to further improve the accuracy and reliability during the transportation of the object 2.

[0086] The projection edge band 5 is received within the recessed band 34, so that the object 2 can be held close to the support surface 18. The object 2 can be held so as to be detachable from the extraction element 32. This can be achieved by means of a protruding edge This is facilitated by the interaction of the band 5 with the stop surface 36. In certain circumstances, the guide element 26 may also The object 2 is separated from the extraction element 32 by the interaction of the protruding edge band 5 with the abutment surface 37. can help.

[0087] FIG. 3 shows the location along the centerline LC of the cam track 28 where the transport element 19 reaches along its path. It shows several important points. In particular, the PR shows that the object 2 is a transport element 19 and a guide element 26. 1 and resting on the support surface 18. A cam element 27 operating in conjunction with a cam follower 29 moves the transfer element 19 towards the object 2. 3, thereby bringing the transfer element 19 into contact with the side wall 3 of the object 2. This occurs at position P1.

[0088] During the passage from the receiving position PR to the contact position P1, the point on the center line LC of the cam track 28 and the axis The distance between the line Z and the transfer element 19 gradually increases. Note that this means moving gradually away from axis Z.

[0089] While the object 2 moves along the path P, the shape of the guide element 26 causes the side wall 3 to move against the guide element 26. This occurs at grip position PP shown in FIG.

[0090] Downstream of the gripping position PP, the transport element 19 transfers the object 2 currently in contact with the guide element 26. continues to move towards the outgoing conveyor 20. While this is happening, the object 2 is first The cam element 27 then moves along a portion of the path that may be substantially circular. 9 to move the transport element 19 further away from the axis Z, e.g., in a radial direction. Thus, the object 2 moves gradually toward the periphery of the support disk 17, and then As shown, the support disc 17 is moved to an intermediate support 21 which may be of the same height as the support disc 17. Move.

[0091] The transport element 19 further comprises a conveyor 20 for conveying the object 2 along the delivery axis U of the delivery conveyor 20. , sliding toward the outside of the support disk 17 until the object 2 is positioned on the outgoing conveyor 20. This is done by pulling the object 2 onto the outgoing conveyor 20 as shown in FIG. This occurs at the delivery location PC.

[0092] After delivering the object 2 to the outfeed conveyor 20, the transport element 19 again The cam 29 operates in conjunction with the cam follower 29 until it reaches a receiving position PR where it receives the object 2. It is moved towards the axis Z by the cam element 27.

[0093] Although the above examples always refer to an object 2 having a protruding edge band 5, it is possible to use the above-described method and device The use of the truncated cone-shaped wall or the twisted ... Moving the object away from a mold 9, which typically has walls that narrow upward from a support surface 18. In this case, the transport element 19 is in the retracted position, so that the transport element 19 and the object Receiving the object 2 on the support surface 18 while there is a gap between the side wall 3 of the object 2 and the support surface 18 causes the side wall 3 of the object 2 to move. This helps to avoid interference with the transmission element 19.
