Description

Technical Field

[0001] This invention relates to the field of pharmaceutical filling and pressing equipment technology, specifically to a combined molding device and filling and pressing method for an integrated pharmaceutical filling and pressing machine. Background Technology

[0002] As pharmaceutical filling and pressing production moves towards automation and continuous operation, filling, pressing, and testing processes are gradually being integrated into multi-station production equipment. Compared with traditional manual or semi-automatic production methods, multi-station equipment allows different processes to be carried out sequentially according to a predetermined rhythm. However, products need to be transferred between multiple stations. The tooling not only bears the responsibility of clamping and supporting the products, but also needs to adapt to the operational requirements of different processes. Therefore, the stability of the tooling during station transfer and the consistency of the product's position between different processes directly affect the continuous connection between each process.

[0003] In the existing production process, for products that require sequential filling and pressing, the working position of the product may need to be reconfirmed or established when switching between different processes. When there is relative displacement of tooling or products during the transfer process, it may be difficult to maintain the positional state formed in the previous process in the subsequent process, thereby increasing the adjustment work in the process connection and affecting the stability of continuous operation. Especially when multiple filling and pressing are required, the above problems will become more prominent with repeated process switching.

[0004] In addition, the filling amount and pressing pressure are process parameters that need to be monitored during the filling and pressing process. Different processes have different operating conditions and testing requirements. When the product is transferred between workstations, if the testing position or testing relationship needs to be re-established, it is easy to increase the connection between the testing process and the process, which is not conducive to continuous and stable process monitoring of the filling and pressing process.

[0005] Therefore, it is still necessary to further improve the positioning and operational status of products during the transition between different processes in the existing drug filling and pressing operations, and to enhance the continuity between filling, pressing and process parameter detection. Summary of the Invention

[0006] The purpose of this invention is to provide a combined molding device and a filling and pressing method for an integrated pharmaceutical filling and pressing machine, so as to solve the problems mentioned in the background art, such as the difficulty in maintaining the positioning and working status of the product when switching between different work stations, and the lack of continuity between filling, pressing and process parameter detection.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] In a first aspect, a combined molding device for a pharmaceutical filling and pressing machine is provided, comprising a guide mold base and a guide mold sleeve sleeved on the upper part of the guide mold base;

[0009] The guide mold sleeve is provided with an upper bushing, and the guide mold base is provided with a lower bushing; when the product shell is installed in the combined molding device, the product shell passes through the upper bushing and the lower bushing.

[0010] The outer side of the guide mold base is fitted with a ring screw, which is threadedly connected to the guide mold sleeve. The inner side of the ring screw is provided with a limiting step, which abuts against the guide mold base axially to lock the guide mold base and the guide mold sleeve. The outer periphery of the ring screw is provided with a flange, which is pressed by the fixing parts on the multi-station turntable of the integrated drug filling and pressing machine.

[0011] A filling funnel is fixedly connected to the upper part of the guide mold sleeve. When the product shell is installed in the combined molding device, the central hole of the filling funnel is connected to the inner hole of the product shell. The central hole is used to introduce the medicine into the product shell and to allow the pressing punch to pass through and guide the pressing punch.

[0012] A sensor holder is provided inside the guide mold base, and an integrated sensor is placed inside the sensor holder; when the product shell is installed in the combined molding device, the product shell is in contact with the integrated sensor, and the integrated sensor is used to detect the filling amount during the filling process and the pressing pressure during the pressing process.

[0013] As a further technical solution of the present invention, the flange is stepped, the fixing member includes a quick-change fixing screw, the quick-change fixing screw presses the flange axially; the bottom of the guide mold base is provided with a positioning hole, and the multi-station turntable is provided with a positioning pin inserted into the positioning hole.

[0014] As a further technical solution of the present invention, the outer periphery of the guide sleeve is provided with a threaded portion that is threadedly connected to the ring screw, and an O-ring is fitted at the root of the threaded portion. The O-ring is located between the guide sleeve and the ring screw and is compressed when the ring screw is tightened.

[0015] As a further technical solution of the present invention, the upper end of the guide sleeve is provided with a stepped hole, the lower part of the filling funnel extends into the stepped hole, and is fixedly connected to the guide sleeve by the funnel fixing screw; the central hole of the filling funnel includes a conical hole section and a cylindrical hole section that are interconnected.

[0016] As a further technical solution of the present invention, the sensor fixing seat is located at the bottom of the inner hole of the guide mold seat, and the sensor fixing seat is provided with a stepped hole for accommodating the integrated sensor; the bottom of the guide mold seat is provided with a through hole corresponding to the stepped hole, and the circuit of the integrated sensor is led out through the through hole.

[0017] As a further technical solution of the present invention, the outer periphery of the upper bushing is clearance-fitted with the inner hole of the guide mold sleeve, and the side wall of the guide mold sleeve is threaded with an upper bushing limiting screw. The upper bushing limiting screw extends into the guide mold sleeve and abuts against the upper bushing to restrict the movement of the upper bushing relative to the guide mold sleeve.

[0018] The outer periphery of the lower bushing is clearance-fitted with the inner hole of the guide mold base. The side wall of the guide mold base is threaded with a lower bushing limiting screw. The lower bushing limiting screw extends into the guide mold base and abuts against the lower bushing to restrict the movement of the lower bushing relative to the guide mold base.

[0019] As a further technical solution of the present invention, both the upper bushing and the lower bushing are made of polytetrafluoroethylene material, and both the upper bushing and the lower bushing are provided with a tapered hole section at one end for guiding the product housing into place.

[0020] The filling funnel, the upper bushing, and the lower bushing are all detachable, and can be adapted to different specifications of product housings by replacing the filling funnel with different center hole sizes and the upper and lower bushings with different inner hole sizes.

[0021] Secondly, a filling and pressing method for a combined molding device used in an integrated pharmaceutical filling and pressing machine is provided, comprising:

[0022] The product housing is inserted into the assembly molding device, and the product housing is brought into contact with the integrated sensor inside the assembly molding device;

[0023] The combined molding device carrying the product shell is fixed on the multi-station turntable of the integrated pharmaceutical filling and pressing machine;

[0024] The multi-station turntable drives the assembly molding device to the filling station, and the agent is filled into the product shell through the central hole of the filling funnel of the assembly molding device, and the amount of agent filled is detected by the integrated sensor.

[0025] While keeping the product housing installed on the assembly molding device and in contact with the integrated sensor, the multi-station turntable drives the assembly molding device to move from the filling station to the pressing station.

[0026] At the pressing station, the pressing punch enters the product housing through the central hole to press the agent inside the product housing, and the pressing pressure is detected by the integrated sensor.

[0027] As a further technical solution of the present invention, when the combined molding device is fixed to the multi-station turntable, the positioning pin provided on the multi-station turntable is inserted into the positioning hole at the bottom of the guide mold base of the combined molding device, and the quick-change fixing screw provided on the multi-station turntable presses the flange on the outer periphery of the ring screw of the combined molding device.

[0028] As a further technical solution of the present invention, after completing one drug pressing, the pressing punch is withdrawn from the center hole of the filling funnel, and while keeping the product shell installed in the assembly molding device, the multi-station turntable drives the assembly molding device to move to the subsequent filling station, repeating the drug filling and drug pressing until the drug filling and pressing of the product shell is completed.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] This invention uses a guide mold base, a guide mold sleeve, and upper and lower bushings disposed within the two to support and position the product shell. The guide mold base and the guide mold sleeve are locked together by ring screws, allowing the product shell to move together with the assembly molding device between different stations on a multi-station turntable. During the transfer from the filling station to the pressing station, the product shell does not need to be removed from the assembly molding device and re-clamped, which helps to maintain the installation state and positioning relationship of the product shell between different processes, reduces the impact of repeated clamping and re-establishing positioning relationships during station switching, and improves the continuity and stability of the filling and pressing processes.

[0031] The central hole of the filling funnel is used to collect and introduce the agent during the filling process, and also allows the pressing punch to pass through and guide the pressing punch during the pressing process, so that the agent filling channel and the pressing punch guiding channel are formed by the same filling funnel; combined with the structural relationship of the product shell in the assembly molding device during the station change process, it is beneficial to maintain the correspondence between the filling position and the pressing position, reduce the need to re-establish the independent guiding relationship after the transfer to the pressing station, thereby improving the connection stability between the filling process and the pressing process;

[0032] An integrated sensor is installed within the assembly molding device and maintains contact with the loaded product housing. This ensures that the detection relationship is maintained along with the product housing as it is transferred from the filling station to the pressing station. This allows for the separate detection of the filling amount during the filling process and the pressing pressure during the pressing process. Consequently, it eliminates the need to re-establish the detection relationship between the product and the detection element for each filling and pressing process. This facilitates continuous detection during the filling, transfer, and pressing processes and provides a detection basis for process monitoring of the filling amount and pressing pressure.

[0033] The ring screw is threadedly connected to the guide mold sleeve and acts axially on the guide mold base through the limiting step on its inner side to lock the guide mold base and the guide mold sleeve. On the other hand, its outer flange can be pressed by the fixing parts on the multi-station turntable, so that the same ring screw can participate in the locking inside the combined molding device and the fixing between the combined molding device and the multi-station turntable at the same time. This helps to reduce the relative movement between the guide mold base and the guide mold sleeve and limit the axial movement of the combined molding device relative to the multi-station turntable, thereby improving the overall stability of the combined molding device during station switching and filling and pressing processes.

[0034] Positioning is achieved by the positioning pins on the multi-station turntable and the positioning holes at the bottom of the guide mold base. The flange on the outer circumference of the ring screw is axially pressed by the quick-change fixing screws. This allows for the simultaneous positioning and fixing of the assembly molding device on the multi-station turntable, facilitating the loading, fixing, and unfixing of the assembly molding device on the turntable. The O-ring seal between the guide mold sleeve and the ring screw is compressed when the ring screw is tightened. The resulting elasticity helps reduce the possibility of loosening of the threaded connection and further improves the ability to maintain the locking state of the guide mold base and the guide mold sleeve.

[0035] The upper and lower bushings are positioned between the product housing and the guide mold sleeve and guide mold base, and are made of polytetrafluoroethylene (PTFE). The self-lubricating properties of this material can reduce friction during the insertion and removal of the product housing, and help reduce the impact on the outer wall of the product housing. The tapered hole sections provided in the upper and lower bushings also help guide the insertion and removal of the product housing.

[0036] The filling funnel, upper bushing, and lower bushing adopt a detachable structure. By replacing the filling funnel with different center hole sizes and the upper and lower bushings with different inner hole sizes, a filling and pressing channel and guiding and positioning structure that are compatible with product shells of different specifications can be formed. This allows the main structure of the same assembly molding device to be adapted to product shells of different specifications, which helps to improve the specification adaptability of the device and reduce the need to replace the molding tooling as a whole due to changes in product specifications.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figures 1-7 Example 1: A combined molding device for a pharmaceutical filling and pressing machine, comprising a guide mold base 12 and a guide mold sleeve 4 sleeved on the upper part of the guide mold base 12;

[0047] The guide mold sleeve 4 is provided with an upper bushing 5, and the guide mold base 12 is provided with a lower bushing 9. Further, the outer periphery of the upper bushing 5 is clearance-fitted with the inner hole of the guide mold sleeve 4, and the side wall of the guide mold sleeve 4 is threaded with an upper bushing limiting screw 3. The upper bushing limiting screw 3 extends into the guide mold sleeve 4 and abuts against the upper bushing 5 to restrict the movement of the upper bushing 5 relative to the guide mold sleeve 4. The outer periphery of the lower bushing 9 is clearance-fitted with the inner hole of the guide mold base 12, and the side wall of the guide mold base 12 is threaded with a lower bushing limiting screw 31. The lower bushing limiting screw 31 extends into the guide mold base 12 and abuts against the lower bushing 9 to restrict the movement of the lower bushing 9 relative to the guide mold base 12.

[0048] In this embodiment, the upper bushing limiting screw 3 and the lower bushing limiting screw 31 limit the upper bushing 5 and the lower bushing 9 respectively, so as to reduce the possibility of the upper bushing 5 and the lower bushing 9 slipping or falling out during the insertion and removal of the product housing 6 and the transfer of the assembly molding device.

[0049] With the product housing 6 installed in the assembly molding device, the product housing 6 passes through the upper bushing 5 and the lower bushing 9; furthermore, both the upper bushing 5 and the lower bushing 9 are made of polytetrafluoroethylene material, and both the upper bushing 5 and the lower bushing 9 have a tapered hole section at one end for guiding the product housing 6 into place.

[0050] The inner hole of the upper bushing 5 guides the upper part of the product housing 6, so that the inner hole of the product housing 6 after installation can correspond to the center hole of the filling funnel 2; the lower bushing 9 guides the lower part of the product housing 6, so that the product housing 6 can be stably placed in the guide mold base 12; the tapered hole sections on the upper bushing 5 and the lower bushing 9 facilitate the installation and removal of the product housing 6.

[0051] The upper bushing 5 and the lower bushing 9 are located between the product housing 6 and the guide mold sleeve 4 and the guide mold base 12, so that the product housing 6 is separated from the guide mold sleeve 4 and the guide mold base 12. By utilizing the self-lubricating properties of polytetrafluoroethylene material, the friction between the product housing 6 and the upper bushing 5 and the lower bushing 9 during the insertion and removal of the product housing 6 can be reduced, and it is beneficial to protect the outer wall of the product housing 6.

[0052] A ring screw 8 is fitted on the outer side of the guide mold base 12. The ring screw 8 is threadedly connected to the guide mold sleeve 4. A limiting step is provided on the inner side of the ring screw 8. The limiting step abuts against the guide mold base 12 axially to lock the guide mold base 12 and the guide mold sleeve 4. Furthermore, the outer periphery of the guide mold sleeve 4 is provided with a threaded part that is threadedly connected to the ring screw 8. An O-ring seal 7 is fitted at the root of the threaded part. The O-ring seal 7 is located between the guide mold sleeve 4 and the ring screw 8 and is compressed when the ring screw 8 is tightened.

[0053] Specifically, as the ring screw 8 engages with the guide mold sleeve 4, the ring screw 8 moves axially, causing the limiting step on its inner side to act axially on the guide mold base 12, thereby locking the guide mold base 12 and the guide mold sleeve 4. Through the above locking relationship, the possibility of relative wobbling between the guide mold base 12 and the guide mold sleeve 4 when the combined molding device moves between different stations with the multi-station turntable can be reduced.

[0054] While tightening the ring screw 8, the O-ring seal 7 is compressed, causing the O-ring seal 7 to undergo elastic deformation. This elastic effect can prevent the threaded connection between the ring screw 8 and the guide mold sleeve 4 from loosening, thereby helping to maintain the locked state of the guide mold seat 12 and the guide mold sleeve 4.

[0055] The outer periphery of the ring screw 8 is provided with a flange, which is pressed by the fixing component on the multi-station turntable of the drug filling and pressing machine; further, the flange is stepped, and the fixing component includes a quick-change fixing screw, which presses the flange axially; the bottom of the guide mold base 12 is provided with a positioning hole, and the multi-station turntable is provided with a positioning pin inserted into the positioning hole.

[0056] After the assembly molding device is installed in the corresponding mounting position of the multi-station turntable, the position of the assembly molding device relative to the multi-station turntable is determined by the positioning hole at the bottom of the guide mold base 12 and the positioning pin on the multi-station turntable; the quick-change fixing screw presses the flange of the ring screw 8 axially to limit the axial movement of the assembly molding device relative to the multi-station turntable; thus, the assembly molding device can move between the filling station, the pressing station and the subsequent station with the multi-station turntable while maintaining the installation state.

[0057] A filling funnel 2 is fixedly connected to the upper part of the guide sleeve 4. When the product shell 6 is installed in the assembly molding device, the central hole of the filling funnel 2 is connected to the inner hole of the product shell 6. The central hole is used to introduce the medicine into the product shell 6 and to allow the pressing punch to pass through and guide the pressing punch. Furthermore, the upper end of the guide sleeve 4 is provided with a stepped hole, and the lower part of the filling funnel 2 extends into the stepped hole and is fixedly connected to the guide sleeve 4 by the funnel fixing screw 1. The central hole of the filling funnel 2 includes a conical hole section and a cylindrical hole section that are connected to each other.

[0058] During the filling process, the conical hole section of the filling funnel 2 is used to receive and collect the agent supplied by the filling station, so that the agent enters the inner hole of the product shell 6 through the cylindrical hole section connected with the conical hole section; during the pressing process, the pressing punch enters the product shell 6 through the central hole of the filling funnel 2, and the central hole of the filling funnel 2 also guides the pressing punch.

[0059] The filling funnel 2 is positioned by the stepped hole at the upper end of the guide mold sleeve 4 through its lower part, and the two are fixed by the funnel fixing screw 1 so that the filling funnel 2 remains stable relative to the guide mold sleeve 4 when the assembly molding device is transferred between different stations.

[0060] A sensor holder 11 is provided inside the guide mold base 12, and an integrated sensor 10 is placed inside the sensor holder 11. When the product housing 6 is installed in the assembly molding device, the product housing 6 is in contact with the integrated sensor 10. The integrated sensor 10 is used to detect the filling amount during the filling process and the pressing pressure during the pressing process. Furthermore, the sensor holder 11 is located at the bottom of the inner hole of the guide mold base 12, and the sensor holder 11 is provided with a stepped hole for accommodating the integrated sensor 10. The bottom of the guide mold base 12 is provided with a through hole corresponding to the stepped hole, and the circuit of the integrated sensor 10 is led out through the through hole.

[0061] The sensor mounting base 11 is used to accommodate the integrated sensor 10 and provide lead-out conditions for the lines of the integrated sensor 10; after the lines of the integrated sensor 10 are led out through the through hole at the bottom of the guide mold base 12, they can be connected to the corresponding sensor interface in the integrated drug filling and pressing machine.

[0062] During the process of the combined molding device being transferred from the filling station to the pressing station along with the multi-station turntable, the product shell 6 remains installed inside the combined molding device and in contact with the integrated sensor 10, so that the integrated sensor 10 can perform detection during the drug filling process and the drug pressing process respectively; at the filling station, the integrated sensor 10 is used to acquire detection information corresponding to the drug filling amount; at the pressing station, the integrated sensor 10 is used to acquire detection information corresponding to the pressing pressure and transmit the corresponding detection information to the integrated drug filling and pressing machine;

[0063] Furthermore, the filling funnel 2, the upper bushing 5, and the lower bushing 9 are all detachable, and can be adapted to different specifications of product housing 6 by replacing the filling funnel 2 with different center hole sizes and the upper bushing 5 and the lower bushing 9 with different inner hole sizes.

[0064] For product housings 6 with different inner hole sizes or external specifications, a filling funnel 2 with a corresponding center hole size can be selected, and an upper bushing 5 and a lower bushing 9 with corresponding inner hole sizes can be selected; by replacing the above components, the combined molding device can be adapted to the filling and pressing operations of products of different specifications.

[0065] In this embodiment, the assembly molding device can be assembled as follows: First, the integrated sensor 10 is placed in the sensor fixing seat 11, and the sensor fixing seat 11 is placed at the bottom of the inner hole of the guide mold seat 12; the lower bushing 9 is installed in the guide mold seat 12, and the lower bushing 9 is limited by the lower bushing limiting screw 31; the upper bushing 5 is installed in the guide mold sleeve 4, and is limited by the upper bushing limiting screw 3; the lower part of the filling funnel 2 is placed in the stepped hole at the upper end of the guide mold sleeve 4, and fixed by the funnel fixing screw 1.

[0066] Subsequently, the product housing 6 is placed inside the guide mold base 12 equipped with the lower bushing 9, so that the product housing 6 comes into contact with the integrated sensor 10; the guide mold sleeve 4 equipped with the upper bushing 5 is fitted onto the upper part of the guide mold base 12, so that the product housing 6 passes through the upper bushing 5 and the lower bushing 9; the O-ring seal 7 is fitted onto the root of the threaded portion of the guide mold sleeve 4, and then the ring screw 8 is fitted onto the outside of the guide mold base 12 and screwed into the guide mold sleeve 4. The guide mold base 12 and the guide mold sleeve 4 are locked by the limiting step of the ring screw 8, thereby completing the assembly of the combined molding device.

[0067] Example 2: A filling and pressing method for a combined molding device used in a pharmaceutical filling and pressing integrated machine, comprising:

[0068] The product housing 6 is inserted into the assembly molding device and the product housing 6 is brought into contact with the integrated sensor 10 inside the assembly molding device.

[0069] After the product housing 6 is installed, it passes through the upper bushing 5 and the lower bushing 9. The upper bushing 5 and the lower bushing 9 guide and position the product housing 6 and keep the product housing 6 in contact with the integrated sensor 10.

[0070] The assembly molding device carrying the product shell 6 is fixed on the multi-station turntable of the pharmaceutical filling and pressing machine; further, when the assembly molding device is fixed on the multi-station turntable, the positioning pin set on the multi-station turntable is inserted into the positioning hole at the bottom of the guide mold base 12 of the assembly molding device, and the quick-change fixing screw set on the multi-station turntable presses the flange on the outer periphery of the annular screw 8 of the assembly molding device.

[0071] The positioning pin and positioning hole are used to determine the installation position of the combined molding device on the multi-station turntable. The quick-change fixing screw restricts the axial movement of the combined molding device relative to the multi-station turntable through the flange of the retaining ring screw 8. After the combined molding device is fixed, the line of the integrated sensor 10 is led out through the through hole at the bottom of the guide mold base 12 and connected to the corresponding sensor interface on the drug filling and pressing integrated machine, so that the integrated sensor 10 enters the detection state.

[0072] The multi-station turntable drives the assembly molding device to the filling station, and fills the agent into the product shell 6 through the center hole of the filling funnel 2 of the assembly molding device, and detects the filling amount of the agent through the integrated sensor 10.

[0073] After the combined molding device reaches the filling station, the filling funnel 2 receives the agent supplied by the filling station. The agent is collected through the conical hole section of the filling funnel 2 and enters the inner hole of the product shell 6 through the central hole. During the process of the agent entering the product shell 6, the integrated sensor 10 acquires the detection information corresponding to the agent filling amount and transmits the corresponding detection information to the agent filling and pressing integrated machine.

[0074] While keeping the product housing 6 installed in the assembly molding device and in contact with the integrated sensor 10, the multi-station turntable drives the assembly molding device to move from the filling station to the pressing station.

[0075] During the above-mentioned transfer process, it is not necessary to remove the product housing 6 from the assembly molding device. The product housing 6 is transferred from the filling station to the pressing station together with the assembly molding device, and continues to be guided by the upper bushing 5 and the lower bushing 9 and in contact with the integrated sensor 10. Thus, the assembly molding device moves together with the product housing 6 between different stations.

[0076] At the pressing station, the pressing punch enters the product housing 6 through the central hole to press the agent inside the product housing 6, and the pressing pressure is detected by the integrated sensor 10.

[0077] After the combined molding device reaches the pressing station, the pressing punch enters the product shell 6 through the central hole of the filling funnel 2, which is used to supply the agent during filling. The central hole of the filling funnel 2 guides the pressing punch during its movement. When the pressing punch acts on the agent in the product shell 6, the integrated sensor 10 acquires the detection information corresponding to the pressing pressure and transmits the corresponding detection information to the integrated agent filling and pressing machine.

[0078] Furthermore, after completing one injection pressing, the pressing punch is withdrawn from the center hole of the filling funnel 2, and while keeping the product shell 6 installed in the assembly molding device, the multi-station turntable drives the assembly molding device to the subsequent filling station, repeating the injection filling and injection pressing until the injection filling and pressing of the product shell 6 is completed.

[0079] Specifically, after one pressing is completed, the pressing punch exits the center hole of the filling funnel 2, and the multi-station turntable continues to rotate, so that the combination molding device enters the subsequent filling station and performs agent filling and agent pressing again; the above filling and pressing process can be repeated according to the product filling and pressing process, and the product shell 6 remains installed in the combination molding device during the repetition process.

[0080] After the predetermined filling and pressing of the reagent is completed, release the quick-change fixing screw from the flange of the ring screw 8 and release the positioning of the assembly molding device on the multi-station turntable. Remove the assembly molding device from the multi-station turntable. Then loosen the threaded connection between the ring screw 8 and the guide mold sleeve 4, release the locking state between the guide mold base 12 and the guide mold sleeve 4, separate the guide mold sleeve 4 from the guide mold base 12, and take out the product shell 6 that has been filled and pressed.

[0081] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
