Description

Technical Field

[0001] The invention relates to a blow-fill-seal device and a production method thereof, and in particular to a multi-specification mold system and a production method of the blow-fill-seal device. Background Art

[0002] like Figure 1 As shown, the continuous blowing, filling and sealing equipment continuously extrude the molten plastic tube embryo without cutting it off and convey it to a set of vertically running forming molds. The forming mold mainly includes a bottle body forming mold and a sealing mold. The forming mold opens and closes the mold in the center on the left and right. The downward speed of the forming mold lifting mechanism is consistent with the speed of the parison extrusion to ensure that the plastic ampoule completes the forming, filling and sealing processes at one time under sterile conditions. The entire cycle is completed within 7-10 seconds. The detailed working principle of the continuous blowing, filling and sealing equipment is disclosed in Chinese patent document CN114835078A, a continuous production blowing, filling and sealing equipment and its use method, a blowing, filling and sealing mold device and forming method, and a continuous blowing, filling and sealing equipment and its use method. The plastic ampoule bottle sheet obtained by continuous forming is conveyed to the punching station through a mesh belt. The punching station is equipped with a punching die for punching the sheet, thereby separating the plastic ampoule bottle from the waste.

[0003] Continuous BFS equipment is usually equipped with multiple sets of molds of different specifications (including forming molds and punching molds). The length of the forming sheet and the filling capacity of molds of different specifications are different. Therefore, each set of molds is equipped with an independent motion curve (taking the forming mold as an example, including the speed and time of the mold lifting, when the mold is opened and closed, etc.) and alarm logic (for example, the actual motion curve of the mold does not match the set motion curve due to equipment failure, etc.). However, since the size of the mold and the internal bottle style are very similar, manual identification can easily cause the mold to match the motion curve and alarm logic incorrectly, resulting in the risk of damage to the mold or filling needle during equipment operation. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a multi-specification mold system for a blow-fill-seal device which is beneficial to reducing the risk of human operation, preventing damage to the mold and the filling needle, and improving the production efficiency.

[0005] The present invention further provides a method for producing a multi-specification mold system of the above-mentioned blow-fill-seal equipment.

[0006] A multi-specification mold system for a blow-fill-seal device comprises an identification component and at least two molds of different specifications, wherein the identification component is used to determine whether the specifications of the retrieved molds match the specifications required for production by the blow-fill-seal device and whether the molds with matching specifications are accurately installed on the blow-fill-seal device.

[0007] As a further improvement of the above technical solution: the identification component includes a first detection component for identifying mold specifications, a second detection component for detecting whether the mold is accurately installed on the blow-fill-seal device, and a control module of the blow-fill-seal device, the second detection component is arranged on the mold, and the positions of the second detection components on molds of different specifications are different. The blow-fill-seal device is provided with a positioning part corresponding to each of the second detection components one by one, the control module stores motion curves and alarm logic of molds of different specifications, and the first detection component and the second detection component are both connected to the control module signal.

[0008] As a further improvement of the above technical solution: each of the molds and the first detection member is arranged in a mold storage warehouse.

[0009] As a further improvement of the above technical solution: the mold includes a forming mold, the forming mold includes a mold frame, a sealing mold and a plurality of bottle body forming molds of different specifications, the mold frame and the sealing mold are arranged on a blow-fill-seal device, the identification component includes a first detection component for identifying the specifications of the bottle body forming mold, a second detection component for detecting whether the installation position of the bottle body forming mold on the mold frame is accurate, and a control module of the blow-fill-seal device, the second detection component is arranged on the bottle body forming mold, and the positions of the second detection components on bottle body forming molds of different specifications are different, the mold frame is provided with a positioning part corresponding to each of the second detection components, the control module stores motion curves and alarm logic of molds of different specifications, and the first detection component and the second detection component are both connected to the control module signal.

[0010] As a further improvement of the above technical solution: each of the bottle body forming molds and the first detection component is arranged in a mold storage library.

[0011] As a further improvement of the above technical solution: the mold storage warehouse is provided with a warehouse door and a third detection member for detecting the switch status of the warehouse door.

[0012] As a further improvement of the above technical solution: the positioning portion is a positioning groove.

[0013] A method for producing a multi-specification mold system for the above-mentioned blow-fill-seal equipment comprises the following steps:

[0014] S1. Retrieving molds: Before the BFS equipment is put into production, the control module sets the mold motion curve and alarm logic required for production, and the mold storage warehouse retrieves the mold. The first detection component identifies the specifications of the retrieved mold and sends the specifications to the control module. The control module determines whether the retrieved mold specifications match the motion curve and alarm logic required for production. If they match, step S2 is executed. If not, the system alarms.

[0015] S2, installing the mold: the retrieved mold is installed on the BFS equipment. If the second detection element detects the corresponding positioning part, step S3 is executed. If the corresponding positioning part cannot be detected, the system alarms.

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] Embodiment 1

[0034] like Figures 1 to 3 As shown, the multi-specification mold system of the blow-fill-seal device of this embodiment includes an identification component and at least two molds 2 of different specifications (including a forming mold 21 and a punching mold 22). The identification component is used to determine whether the specifications of the retrieved mold 2 match the specifications required for production by the blow-fill-seal device 4 and whether the mold 2 with matching specifications is accurately installed on the blow-fill-seal device 4.

[0035] The multi-specification mold system of this embodiment includes an identification component. The identification component is used to determine whether the specifications of the retrieved mold 2 match the specifications required for production by the BFS device 4 on the one hand, and to determine whether the mold 2 with matching specifications is accurately installed on the BFS device 4 on the other hand. If the specifications do not match or the installation position is incorrect, an alarm is given to stop the machine in time, and manual intervention is performed, thereby ensuring that the retrieved mold 2 has accurate specifications and is accurately installed on the BFS device 4. The system has a high degree of automation, high efficiency, and good reliability, reduces the risk of human operation, and is conducive to preventing the mold 2 and the filling needle from being damaged by collision.

[0036] Furthermore, in this embodiment, the identification component includes a first detection component 3 for identifying the specifications of the mold 2, a second detection component 5 for detecting whether the installation position of the mold 2 on the blow-fill-seal device 4 is accurate, and a control module of the blow-fill-seal device 4. The second detection component 5 is arranged on the mold 2, and the positions of the second detection components 5 on molds 2 of different specifications are different. The blow-fill-seal device 4 is provided with a positioning portion 41 corresponding to each second detection component 5 one by one. The control module stores the motion curves and alarm logic of molds 2 of different specifications. The first detection component 3 and the second detection component 5 are both connected to the control module signal. Before the BFS device 4 is put into production, the control module sets the motion curve and alarm logic of the mold 2 required for production, the mold storage 1 retrieves the mold 2, the first detection component 3 identifies the specifications of the retrieved mold 2 and sends the specifications to the control module, and the control module can determine whether the specifications of the retrieved mold 2 match the motion curve and alarm logic required for production. If they match, the mold 2 can be installed; the retrieved mold 2 is installed on the BFS device 4, if the second detection component 5 detects the corresponding positioning part 41, it indicates that the retrieved mold 2 is installed in place, the BFS device 4 can be produced, and the reliability is good, which is conducive to preventing the mold 2 and the filling needle from being damaged by collision. Among them, the first detection component 3 can be, for example, visual recognition, barcode, QR code recognition, etc., and the second detection component 5 can be, for example, a position sensor, a travel switch, etc.

[0037] Furthermore, in this embodiment, each mold 2 and the first detection member 3 are arranged in a mold storage 1. The mold storage 1 can provide protection for each mold 2 and the first detection member 3 to avoid contamination and damage, and the first detection member 3 can identify the specifications of the retrieved mold 2 as early as possible.

[0038] Furthermore, in this embodiment, the mold storage warehouse 1 is provided with a door 12 and a third detection member 11 for detecting the opening and closing state of the door 12. When the third detection member 11 detects that the door 12 is opened and then closed again, it indicates that the retrieved mold 2 has been shipped out of the warehouse. At this time, the first detection member 3 sends the specification information of the mold 2 to the control module, further improving the reliability of the system.

[0039] As a preferred embodiment, the positioning portion 41 is a positioning groove, which is convenient for positioning and does not affect the installation of the mold 2 on the blow-fill-seal device 4. Of course, in other embodiments, the positioning portion 41 can also be a positioning protrusion, a positioning hole, etc., which will not be repeated.

[0040] Embodiment 2

[0041] like Figure 4 As shown, in another embodiment of the multi-specification mold system of the blow-fill-seal device of this embodiment, the mold 2 can be retrieved as a whole set, taking the forming mold 21 as an example, or each forming mold 21 can share a mold frame 211 and a sealing mold 212, and the mold frame 211 and the sealing mold 212 are always installed on the blow-fill-seal device 4, so that only the bottle body forming mold 213 of the required specifications for production needs to be retrieved, which is conducive to reducing the cost of the mold 2. Therefore, in this embodiment: the mold 2 includes the forming mold 21, the forming mold 21 includes the mold frame 211, the sealing mold 212 and a plurality of bottle body forming molds 213 of different specifications, the mold frame 211 and the sealing mold 212 are arranged on the blow-fill-seal device 4, the positioning part 41 is arranged on the mold frame 211, each bottle body forming mold 213 and the first detection member 3 are stored in the mold storage 1, and the second detection member 5 is arranged on the bottle body forming mold 213. During operation, the bottle body forming mold 213 of the required specifications for production is first retrieved, and then the retrieved bottle body forming mold 213 is ensured to be accurately installed at the corresponding position of the mold frame 211 .

[0042] Embodiment 3

[0043] like Figure 5 As shown, the production method of the multi-specification mold system of the blow-fill-seal equipment of this embodiment includes the following steps:

[0044] S1. Retrieving mold 2: Before the BFS device 4 starts production, the control module sets the motion curve and alarm logic of the mold 2 required for production. The mold storage 1 retrieves the mold 2. The first detection component 3 identifies the specifications of the retrieved mold 2 and sends the specifications to the control module. The control module determines whether the specifications of the retrieved mold 2 match the motion curve and alarm logic required for production. If they match, step S2 is executed. If not, the system alarms.

[0045] S2, installing the mold 2: the retrieved mold 2 is installed on the BFS device 4. If the second detection member 5 detects the corresponding positioning portion 41, step S3 is executed. If the corresponding positioning portion 41 is not detected, the system alarms.

[0046] S3. The second detection component 5 sends a detection signal to the control module, and the blow-fill-seal device 4 performs production.

[0047] The production method of the multi-specification mold system of the BFS equipment of this embodiment is conducive to ensuring that the specifications of the retrieved mold 2 are accurate, match the scale required for the production of the BFS equipment 4, and are accurately installed on the BFS equipment 4. It has a high degree of automation, high efficiency, and good reliability, reduces the risk of human operation, and is conducive to preventing the mold 2 and the filling needle from being damaged by collision.

[0048] Preferably, in order to further improve reliability, a manual confirmation step may be performed after step S2 to confirm whether the installed mold 2 is consistent with the production requirements of the BFS device 4. When the production requirements after confirmation are inconsistent with the automatic matching mold motion curve and alarm logic, or when no signal is detected, the system alarms, the equipment stops running, and manual intervention is performed; when the production requirements after confirmation are consistent with the automatic matching mold motion curve and alarm logic, the system interlocks and enters the production mode.

[0049] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
