Description

Technical Field

[0001] This application relates to the field of pharmaceutical technology, and particularly to a tablet automatic inversion laser drilling and inspection machine, and a drilling method.

Background Art

[0002] Oral osmotic pump tablets with sustained release can be made by utilizing the osmotic pressure principle, and thus it is possible to uniformly release drugs in the body over a long period of time. The oral osmotic pump tablet coats a semi-permeable membrane outside the tablet core, makes holes in the membrane by laser, and after oral ingestion, the water in the body enters the tablet core through the semi-permeable membrane, dissolves the drug or osmotic pressure generator to generate osmotic pressure, and continuously extrudes the drug, which is also called an osmotic pump tablet. There are various types of osmotic pump tablets, and common ones include single-chamber osmotic pump tablets, double-chamber osmotic pump tablets, etc.

[0003] In a single-chamber osmotic pump tablet, the osmotic pressure generator and the drug are mixed, and there is no need to distinguish the front and back of the tablet. By making one hole on each of the front and back of the tablet, the drug is released. On the other hand, a double-chamber osmotic pump tablet has a two-layer structure. One layer is the drug storage part, and the other layer is the osmotic pressure generator. The osmotic pressure generator absorbs water and expands to generate a propelling force to extrude the drug from the hole. Therefore, in such a controlled-release tablet, holes must be made on the surface of the coating layer of the drug storage part, otherwise, the drug cannot be released. Currently, the drilling device for double-chamber osmotic pump tablets has low drilling efficiency and cannot meet the requirements of industrial production. Therefore, improving the drilling efficiency of double-chamber osmotic pump tablets has become an urgent technical problem to be solved in this field.

Many specific details are included below to facilitate a complete understanding of the present application.

[0021] Furthermore, where the terms “first” and “second” appear, they are merely descriptive and should not be understood as expressing or implying relative importance or implicitly specifying the number of technical features described. This expresses or implies that features limited by “first” and “second” include at least one such feature. Where the term “plural” appears in this description, “plural” means at least two, for example, two or three, unless otherwise specifically and clearly defined.

[0022] In this application, unless otherwise explicitly defined and limited, terms such as “attachment,” “connection,” “linking,” and “fixing” should be understood broadly. For example, these may be fixed connections, removable connections, or integrated connections; they may be mechanical connections, electrical connections, direct connections, indirect connections via an intermediate medium, connections within two elements, or interactions between two elements.

[0025] This application provides an automatic tablet reversal laser perforation and inspection machine, which, as shown in Figures 1 to 4, may include a transport device 1000, a reversal device 2000, and a perforation device 3000. In addition, the automatic tablet reversal laser perforation and inspection machine may be further provided with a return device 4000 and one or more removal devices 5000 as needed. The automatic tablet reversal laser perforation and inspection machine can be used for perforation processing of objects such as a two-layered twin-chamber osmotic pump tablet. In the twin-chamber osmotic pump tablet shown in Figure 2, one side is a shaded portion and the other side is an unshaded portion, which means that one layer of the twin-chamber osmotic pump tablet is a drug reservoir and the other layer is an osmotic pressure generating agent. Since a hole needs to be made on the coated layer side of the drug reservoir, in order to easily explain the technical means, the state in which the drug reservoir side of the twin-chamber osmotic pump tablet faces upward is limited to the state in which the surface of the object faces upward and is indicated by the unshaded portion of the surface, while the state in which the drug reservoir side of the twin-chamber osmotic pump tablet faces downward is limited to the state in which the back surface of the object faces upward and is indicated by the shaded portion of the surface. In addition, those skilled in the art may, as necessary, apply the tablet automatic reversal laser perforation and inspection machine to other perforation methods, but are not limited thereto.

[0026] The conveying device 1000 is a device for conveying an object. The conveying device 1000 may have a clearly defined conveying trajectory 1000a predetermined in advance. The conveying trajectory 1000a includes at least an initial work area, a reversal work area, a drilling work area, and a finishing work area. The conveying device 1000 conveys the object along the conveying trajectory 1000a by its own active conveying so that the object located in the initial work area passes sequentially through the reversal work area, the drilling work area, and the finishing work area, undergoing different processing in each work area. Therefore, the conveying trajectory 1000a is predetermined and fixed in the conveying device 1000, and the positions of the multiple work areas, such as the initial work area, reversal work area, drilling work area, and finishing work area, which are sequentially divided along the conveying trajectory 1000a, are also fixed. The conveying device 1000 is driven to move the object along the conveying trajectory 1000a to multiple different areas, so that it passes through each area in order, such as the initial work area, the reversal work area, the drilling work area, and the finishing work area.

[0027] The conveying device 1000 includes a conveying platform 1100, which has a plurality of storage grooves 1100a. The storage grooves 1100a store objects so that they are arranged regularly on the conveying platform 1100 according to a pre-set arrangement rule for the storage grooves 1100a. The storage grooves 1100a include a storage area 1120a and an airflow area 1110a that communicate with each other. The diameter of the holes in the storage area 1120a allows objects to enter, while the diameter of the holes in the airflow area 1110a prohibits objects from entering. By making the diameter of the holes in the airflow area 1110a larger than the diameter of the holes in the storage area 1120a, objects are restricted to the storage area 1120a. Therefore, objects are stored within the storage grooves 1100a mainly by the space of the storage area 1120a.

[0028] In one embodiment, the transport platform 1100 further includes a base platform 1110 and a mobile platform 1120. A storage hole area 1120a is provided in the mobile platform 1120, and an airflow hole area 1110a is installed in the base platform 1110. A drive unit 1200 is provided on the base platform 1110 and drives the mobile platform 1120 to rotate relative to the base platform 1110, thereby enabling different storage hole areas 1120a to communicate with different airflow hole areas 1110a in sequence.

[0029] For example, as the mobile platform 1120 rotates, the storage hole area 1120a of the mobile platform 1120 also rotates, and if one or more storage hole areas 1120a pass through multiple work areas such as the initial work area, inversion work area, return work area, drilling work area, removal work area, and finishing work area, the storage hole area 1120a is formed so that its vertical position corresponds to that of storage hole areas 1120a located in different work areas such as the initial work area, inversion work area, return work area, drilling work area, removal work area, and finishing work area, and furthermore, a state is formed in which they communicate with each other under this correspondence.

[0030] Therefore, as the mobile platform 1120 rotates relative to the base platform 1110 on the transport platform 1100, each storage hole area 1120a passes sequentially through an initial work area, a reversal work area, a return work area, a drilling work area, a removal work area, and a finishing work area along the transport trajectory 1000a, thereby moving the object within the storage hole area 1120a along the transport trajectory 1000a. The mobile platform 1120 may be provided with two or more storage hole areas 1120a in a direction perpendicular to the transport trajectory 1000a, and accordingly, the base platform 1110 may be provided with two or more compatible airflow hole areas 1110a in a direction perpendicular to the transport trajectory 1000a, so that two or more storage hole areas 1120a pass through each work area simultaneously, making it possible to perform corresponding processing on two or more objects in different work areas in a single operation.

[0031] In one embodiment, the transport trajectory 1000a may be a circular trajectory having a central axis. The drive unit 1200 drives the mobile platform 1120 to rotate around the central axis. For example, the drive unit 1200 is a rotary motor, and the rotary motor drives the mobile platform 1120 to rotate around the central axis. The transport platform 1100 may or may not be circular. It is sufficient that it can be driven to move the object along a circular trajectory. As a result, each storage hole area 1120a can pass through the initial work area, inversion work area, return work area, drilling work area, removal work area and finishing work area in order along the transport trajectory 1000a, and after completing one rotation, it is possible to repeat passing through multiple work areas such as the initial work area, inversion work area, return work area, drilling work area, removal work area and finishing work area again.

[0032] The automatic tablet reversing laser perforation and inspection machine generates fumes and dust during operation, requiring cleaning at the end of the operation. Since the components of the automatic tablet reversing laser perforation and inspection machine, such as the light source, camera, laser transmitter, solenoid valve, and turntable, cannot all be disassembled for cleaning, normal cleaning is not thorough. Referring to Figure 5, in one embodiment, the conveying device comprises a lifting platform 1130 and a lifting means 1130a. The lifting platform 1130 has a circular recess 1130b on its side edge, and the moving platform is a circular platform that fits into the circular recess 1130b and can also rotate relative to the lifting platform 1130. The lifting means 1130a is mounted on a base platform and is drivably connected to the lifting platform 1130, driving the lifting platform 1130 to move up and down relative to the base platform.

[0033] During operation, the lifting mechanism 1130a controls the lifting platform 1130 to a height parallel to the moving platform 1120, causing the circular platform and the circular recess 1130b to fit together. At the end of the operation, the lifting mechanism 1130a can be controlled to raise the lifting platform 1130 so that it is higher than the moving platform 1120. At this time, the moving platform 1120 can be removed and cleaned separately. In the automatic tablet reversal laser perforation and inspection machine, the storage groove hole 1100a for storing the object is where the most dust accumulates, making it an important area to clean.

[0034] Continuing with Figures 1 and 2, the inversion device 2000 is located in the inversion work area and performs an inversion process on objects that arrive in the inversion work area. More precisely, it performs an inversion process on objects that are facing upwards so that objects that are facing upwards have their front surfaces facing upwards. This is because, during the transport device 1000's transport of objects from the initial work area to the inversion work area, all objects that arrive in the inversion work area include objects with their back surfaces facing upwards and objects with their front surfaces facing upwards. Objects with their front surfaces facing upwards can be directly perforated, eliminating the need for an inversion process. Therefore, the inversion device 2000 primarily performs an inversion process on objects that are facing upwards.

[0035] The identification device 6000 installed in the automatic tablet reversal laser perforation and inspection machine can identify whether the object is in a state where the back side is facing upwards or the front side is facing upwards. The identification device 6000 identifies the orientation status information, perforation status information, etc. of the object as needed, and instructs the corresponding operation of the automatic tablet reversal laser perforation and inspection machine based on the acquired information. The identification device 6000 can acquire necessary information by employing a device such as a camera capable of acquiring image data. For example, the identification device 6000 includes a first information acquisition unit 6100, which is a camera. The first information acquisition unit 6100 is located in the reversal work area and acquires orientation status information of the object that has arrived in the reversal work area. Based on the orientation status information of the object, it identifies whether the object is in a state where the back side is facing upwards or the front side is facing upwards. At this time, the reversal device 2000 identifies the object that has arrived in the reversal work area based on the orientation status information acquired by the first information acquisition unit 6100 and performs a reversal process on the object that is in a state where the back side is facing upwards.

[0036] The perforating device 3000 is located in the perforating work area and performs perforation on objects that arrive in the perforating work area. The perforating device 3000 can perform perforation on objects in multiple ways; for example, a laser processing machine may be used, and a water-cooled 100W carbon dioxide laser processing machine can be selected as needed. Such a laser processing machine operates stably, has adjustable and displayable output, can satisfy large production volumes, and can be set to automatically delay the start of the laser processing machine by 5 minutes after being switched on, effectively protecting the laser processing machine and extending its service life. While the conveying device 1000 is conveying the object from the initial work area to the inversion work area, the inversion device 2000 has already performed inversion on the object whose back surface is facing upwards. Therefore, when the conveying device 1000 conveys the object that has passed through the inversion work area to the perforating work area, the object whose back surface is facing upwards is inverted to a state where the front surface is facing upwards, and the object is ready for perforation.

[0037] In the process described above, the objects supplied to the initial work area may be in a state where the front surface is facing upwards and a state where the back surface is facing upwards. After all the objects are transported to the inversion work area by the transport device 1000, the inversion device 2000 identifies the objects with the back surface facing upwards and performs an inversion process on them, thereby preparing them for the drilling process. After all the objects have been transported to the drilling work area, the drilling device 3000 can directly perform the drilling process. This process significantly improves the drilling efficiency of the objects and satisfies industrial requirements.

[0038] In addition, in one embodiment, the automatic tablet reversal laser perforation and inspection machine is further equipped with a return device 4000, so the transport trajectory 1000a includes a return work area located between the reversal work area and the perforation work area. The return device 4000 is located in the return work area and performs a return process on objects that arrive in the return work area. This is because, after the transport device 1000 transports the object from the initial work area to the reversal work area, the reversal device 2000 performs a reversal process on objects with their back surface facing upwards. However, considering the problem of the reversal success rate by the reversal device 2000, there is a possibility that objects that have not been reversed or whose reversal failed may be transported to the perforation work area. Therefore, by constructing a return work area between the reversal work area and the perforation work area, all objects that arrive in the return work area are re-inspected by the return device 4000.

[0039] The re-inspection of the object can be performed by the identification device 6000 installed in the tablet automatic reversal laser perforation and inspection machine. The identification device 6000 identifies the orientation status information, perforation status information, etc. of the object as needed, and based on the acquired information, instructs the corresponding operation of the tablet automatic reversal laser perforation and inspection machine. The identification device 6000 employs a device such as a camera capable of acquiring image data and can acquire the necessary information. For example, the identification device 6000 is equipped with a second information acquisition unit 6200, which is a camera. The second information acquisition unit 6200 is located in the return work area and acquires the orientation status information of the object that has arrived in the return work area. Based on the orientation status information of the object, it identifies whether the back surface of the object is facing upwards or whether the front surface is facing upwards. At this time, the return device 4000 re-identifies the object that has arrived in the return work area based on the orientation status information acquired by the second information acquisition unit 6200. If the presence of an object with its back surface facing upward is detected, the return process is performed to return the object with its back surface facing upward to the initial work area. The transport device 1000 then transports the object again from the initial work area along the transport trajectory 1000a, and the above steps are repeated.

[0040] In addition, in one embodiment, the tablet automatic reversal laser perforation and inspection machine further comprises at least one removal device 5000, and the transport trajectory 1000a includes at least one removal work area. For example, if there is one removal work area, it may be located between the perforation work area and the finishing work area, and the removal device 5000 will be located in the removal work area. If there are two or more removal work areas, the multiple removal work areas may be located between the perforation work area and the finishing work area, and by arranging the multiple removal work areas sequentially along the transport trajectory 1000a, the objects can pass through each removal work area in sequence.

[0041] Since the removal devices 5000 are installed in the same quantity to suit the removal work area, multiple removal devices 5000 can be located in different removal work areas. The removal devices 5000 perform removal processing on objects that arrive in the removal work area. This is because the transport device 1000 transports the objects sequentially from the initial work area to the inversion work area and the drilling work area, performs drilling processing on each object, collects the objects after drilling processing, and sends them out as finished products in the finishing work area. The finished product storage device 8000 receives and stores the objects that arrive in the finishing work area.

[0042] However, given the issue of the perforation pass rate of the perforation device 3000, it is not guaranteed that all objects will be perforated or that objects after perforation will perfectly conform to the perforation standards. Therefore, a removal work area can be established between the perforation work area and the finishing work area, and all objects that arrive at the removal work area by the removal device 5000 can be reinspected.

[0043] Regarding the re-inspection of the target object, identification is possible using the identification device 6000 installed in the automatic tablet reversal laser perforation and inspection machine. The identification device 6000 identifies the orientation status information, perforation status information, etc. of the target object as needed, and instructs the corresponding operation of the automatic tablet reversal laser perforation and inspection machine based on the acquired information. The identification device 6000 employs a device such as a camera capable of acquiring image data and can acquire the necessary information. For example, the identification device 6000 is equipped with a third information acquisition unit 6300, which is a camera, and the third information acquisition unit 6300 is located in the removal work area and acquires perforation status information of the target object that has arrived in the removal work area. The perforation status information of the target object indicates whether or not the target object has been perforated, whether or not the size of the perforation conforms to the standard, whether or not the position of the perforation is off-center, etc. By comparing this with the perforation standard, defective products of the target object that do not conform to the perforation standard are selected.

[0044] At this time, the removal device 5000 re-identifies the objects that have arrived in the removal work area based on the perforation status information acquired by the third information acquisition unit 6300, and if a defective object that does not conform to the perforation criteria is found, it performs a removal process on it.

[0045] The inversion process by the inversion device 2000, the return process by the return device 4000, and the removal process by the removal device 5000 can all be carried out in multiple ways, such as gripping with a robot arm, fluid collision, and other feasible methods. In one embodiment, the inversion device 2000, return device 4000, and removal device 5000 of the present invention can each perform the corresponding process based on the principle of pneumatics. As shown in Figure 2, in one embodiment, each storage groove hole 1100a includes an airflow hole area 1110a and a storage hole area 1120a, and when the transport platform 1100 is designed as a separable structure including a base platform 1110 and a mobile platform 1120, the storage hole area 1120a is opened in the mobile platform 1120 and the airflow hole area 1110a is installed in the base platform 1110. The shape of the airflow vent area 1110a is not particularly limited, as long as it can be guaranteed that the gas passes through stably and that the object does not fall from the airflow vent area 1110a.

[0046] Based on the airflow vent area 1110a, it is possible to apply airflow to an object, invert the object, or move the position of the object. For example, in one embodiment, the inversion device 2000 is equipped with a first fluid control unit 2100, which applies a positive pressure drive gas or a negative pressure drive gas to an object located in the storage groove hole 1100a via the airflow vent area 1110a, and based on the design of the position and angle of application, the object changes from a state where the back surface is facing upward to a state where the front surface is facing upward within the storage groove hole 1100a. For example, during the inversion process, by applying a positive pressure drive gas or a negative pressure drive gas to the object, it is possible to synergistically coordinate with the centrifugal force during the movement of the object. If the transport trajectory 1000a is circular, the transport device 1000 is driven to periodically rotate the object along the circular trajectory, and in doing so, it is possible to generate an outward centrifugal force and a forward impact force along the circular trajectory on the object. At this time, the first fluid control unit 2100 can apply a positive pressure drive gas or a negative pressure drive gas to an object located in the storage groove hole 1100a via the airflow hole area 1110a. By setting the positive pressure drive gas or negative pressure drive gas to be applied for a certain time, at a certain angle, and at a certain magnitude, it is possible to quickly and accurately invert the object, and the success rate of inversion is also increased. Parameters such as the strength of the applied positive pressure drive gas or negative pressure drive gas can be controlled by solenoid valves or logic controllers, and can be set by those skilled in the art according to their actual needs, and are not particularly limited here.

[0047] Continuing with Figure 3, in one embodiment, the return device 4000 comprises a return pipe 4100 and a second fluid control unit 4200. The return pipe 4100 has an injection pipe port that communicates with the return work area and a discharge pipe port that communicates with the initial work area. The number of return pipes 4100 may be set to one or more, and by fixing the injection pipe port of the return pipe 4100 to a passable position in the storage groove hole 1100a as needed, the injection pipe port of the return pipe 4100 can accurately communicate with the storage groove hole 1100a when the transport device 1000 transports an object in the storage groove hole 1100a. If the corresponding object needs to be returned, the second fluid control unit 4200 can apply a positive pressure drive gas to the object located in the storage groove hole 1100a via the airflow hole area 1110a. The positive pressure drive force causes the object to detach from the storage groove hole 1100a and move along the return pipe 4100, so that the object returns to the initial work area via the return pipe 4100.

[0048] Continuing with Figure 3, in one embodiment, the removal device 5000 comprises a removal pipe 5100 and a third fluid control unit 5200. The removal pipe 5100 has an injection pipe port that communicates with the removal work area and a discharge pipe port that communicates with the removal storage cavity. The number of removal pipes 5100 may be set to one or more, and by fixing the injection pipe port of the removal pipe 5100 to a passable position in the storage groove hole 1100a as needed, when the conveying device 1000 conveys an object in the storage groove hole 1100a, the injection pipe port of the removal pipe 5100 can accurately communicate with the storage groove hole 1100a. When removing the corresponding object, the third fluid control unit 5200 can apply a positive pressure driving gas to the object located in the storage groove hole 1100a via the airflow hole area 1110a. This positive pressure driving force detaches the object from the storage groove hole 1100a and moves it along the removal pipe 5100, causing the object to enter the removal storage cavity via the removal pipe 5100.

[0049] Continuing with reference to Figures 1 and 6, in one embodiment, the tablet automatic reversal laser perforation and inspection machine includes a dispensing device 7000, which includes a supply container 7100 having a supply cavity inside, and an opening communicating with the supply cavity is provided at the bottom of the supply container 7100. The supply container 7100 is positioned so that the opening faces the transport platform 1100 of the transport device 1000, and the opening can cover the initial work area, the covered area may be the entire initial work area or at least a part of the initial work area. The dispensing device 7000 includes a pushing means for introducing the object into the storage groove hole 1100a, for example, a brush for scraping the object. Otherwise, a person skilled in the art may provide a means equivalent to the pushing means for the object, and is not limited thereto as long as the object can be actively introduced into the storage groove hole 1100a.

[0050] Therefore, after the object falls into the supply container 7100, the provided pushing means actively introduces the object into the storage groove holes 1100a, ensuring that after the object is introduced into the storage groove holes 1100a, it can be precisely positioned in each of the fixed storage groove holes 1100a and moved to the inversion work area. Positioning the object in each of the fixed storage groove holes 1100a facilitates subsequent inversion, return, drilling, and removal processes.

[0051] Referring to Figure 6, the dispensing device 7000 further comprises a storage hopper 7200 and a weight sensor 7200a. The storage hopper 7200 stores the object and needs to communicate with the supply container 7100 in order to dispense the object to the supply container 7100. For example, the storage hopper 7200 is located above the supply container 7100 and automatically dispenses the object to the supply container 7100 by gravity, or it actively transports the object to the supply container 7100 by other mechanical structures, but is not limited thereto.

[0052] The storage hopper 7200 is assembled and fixed by a support frame 7200b, and assembly parts 7200c may be provided on the storage hopper 7200, and the storage hopper 7200 is assembled to the support frame 7200b by the assembly parts 7200c. A weight sensor 7200a is provided on the storage hopper 7200 to detect the weight of objects in the storage hopper 7200. Therefore, if the number of objects in the storage hopper 7200 changes, the weight sensor acquires the change in the total weight of the objects, and if the weight data is less than a predetermined value, objects may be automatically added to the storage hopper 7200 using a suitable filling device, or objects may be added manually, but are not limited thereto.

[0053] The present invention provides a perforation method having a transport trajectory 1000a including at least an initial work area, an inversion work area, a return work area, a perforation work area, a removal work area and a finishing work area, and the method includes the step of transporting an object along the transport trajectory 1000a such that the object located in the initial work area passes sequentially through the inversion work area, the return work area, the perforation work area, the removal work area and the finishing work area.

[0054] For at least a portion of the objects that arrive in the inversion work area, an inversion process is performed so that objects with the back side facing upwards have the front side facing upwards, and objects with the back side facing upwards have the front side facing upwards, and then a perforation process is performed on the objects that arrive in the perforation work area and an inversion process is performed on them. If the objects that arrive in the return work area have the back side facing upwards, a return process is performed so that the objects with the back side facing upwards are returned to the initial work area, and if the objects that arrive in the removal work area do not conform to the perforation criteria, a removal process is performed on those objects.

[0055] In the perforation method described above, the objects supplied to the initial work area may be in a state where the front surface is facing upwards or the back surface is facing upwards. After all objects are transported to the inversion work area by the transport device 1000, the inversion device 2000 identifies the objects with the back surface facing upwards and performs an inversion process on these objects, thus preparing them for perforation. After all objects have been transported to the perforation work area, the perforation process can be directly performed by the perforation device 3000. This process significantly improves the perforation efficiency of the objects and satisfies industrial requirements. Furthermore, by re-inspecting the objects before perforation, the perforation process is avoided for objects with the back surface facing upwards. At least one re-inspection is performed before collecting the finished objects, thus avoiding the collection of objects that do not meet the perforation criteria. The above embodiment guarantees a 100% completion rate and effectively improves the perforation efficiency of the objects.

[0056] The technical features of the embodiments described above can be combined in any way. For the sake of brevity, not all combinations of the technical features in the embodiments described above have been explained, but these combinations of technical features should be considered to fall within the scope described herein, as long as they are not contradictory.

[0057] The embodiments described above are merely examples of some embodiments of the present application, and although their descriptions are specific and detailed, they should not be interpreted as limiting the scope of protection of the invention. Furthermore, a person skilled in the art can make some modifications and improvements as long as they do not deviate from the spirit of the present application, and these too fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be the same as that of the claims. [Explanation of Symbols]
