Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pharmaceutical packaging equipment, in particular to a vacuum attenuation leak detection equipment. BACKGROUND

[0002] The vacuum attenuation leak detection machine is a kind of equipment for detecting the integrity or sealing of packaging, which mainly uses the principle of vacuum attenuation leak detection. This detection method is mainly aimed at BFS, glass ampoule, pre-filled needle, and vial injection products. Taking a medicine bottle as an example, during the leak detection operation, the medicine bottle is first placed in a mold cavity in the equipment, and then a vacuum is applied to the mold cavity. The vacuum will cause the gas in the medicine bottle to overflow through the leakage hole. If the medicine bottle contains liquid medicine, when the vacuum degree is lower than the vapor pressure of the liquid, the liquid in the leakage channel will be vaporized. Therefore, if the pressure in the mold cavity increases, it is caused by packaging leakage, and this pressure will be detected by the sensor in the mold cavity.

[0041] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left" and "right" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated position or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0042] Please refer to Figure 1 and Figure 2 The embodiments of the present application provide a vacuum attenuation leak detection equipment for detecting whether the bottle-shaped material 1 is qualified, which comprises an upper and lower feeding device, an annular conveying assembly, a leak detection assembly and a sorting assembly.

[0043] The upper and lower feeding device comprises a feeding device 01 and a discharging device 02, the feeding device 01 is used for conveying undetected materials 1, and the discharging device 02 is used for outputting materials 1 after detection;

[0044] The annular conveying assembly is arranged between the feeding device 01 and the discharging device 02, and comprises an annular synchronous belt 21, a plurality of detection mold cavities 22 and a servo motor 23. The annular synchronous belt 21 is of an annular structure and is sleeved between the feeding device 01 and the discharging device 02. The detection mold cavity 22 is of a cylindrical structure with open ends, and a plurality of detection mold cavities 22 are arranged on the outer side of the annular synchronous belt 21. The servo motor 23 is used for providing power for the operation of the annular synchronous belt 21.

[0045] The leak detection assembly is arranged on the leak detection frame 31 between the feeding device 01 and the discharging device 02 and close to the feeding device 01, and comprises a detection mechanism and a sealing mechanism. The detection mechanism comprises a standard mold cavity 32 and a detection instrument 33. The standard mold cavity 32 is a detection mold cavity 22 in which a standard material 1 is arranged. The sealing mechanism comprises a fixed sealing plate 34 and a movable sealing plate 35. The detection instrument 33 is arranged on the fixed sealing plate 34. The fixed sealing plate 34 can seal one end of the standard mold cavity 32 and the detection mold cavity 22 and is in communication with the detection instrument 33. The movable sealing plate 35 can seal the end of the standard mold cavity 32 and the detection mold cavity 22 away from the fixed sealing plate 34.

[0046] The sorting assembly is arranged on the sorting frame 41 between the leak detection assembly and the discharging device 02 and comprises a rejection mechanism and a collection mechanism. The rejection mechanism is arranged on the sorting frame 41 and is used for pushing out the unqualified material 1 in the detection mold cavity 22. The collection mechanism is arranged on the sorting frame 41 corresponding to the position of the material 1 pushed out by the rejection mechanism and is used for collecting the rejected unqualified material 1.

[0047] It can be understood that the leak detection frame 31 and the sorting frame 41 can be assembled into an integral whole and arranged between the feeding device 01 and the discharging device 02. The vacuum attenuation leak detection equipment sequentially comprises the feeding device 01, the leak detection assembly, the sorting assembly and the discharging device 02 in sequence. The two ends of the annular conveying assembly are arranged on the feeding device 01 and the discharging device 02 respectively and circulate along the length direction of the leak detection frame 31 and the sorting frame 41. The several detection mold cavities 22 arranged thereon pass through the feeding device 01, the leak detection assembly, the sorting assembly and the discharging device 02 in sequence.

[0048] In the embodiment, the leak detection of the material 1 in the detection mold cavity 22 is performed by the differential pressure method. The fixed sealing plate 34 has a special gas path design, one end of which is connected to the hollow part of the standard mold cavity and the other end is connected to the detection instrument 33. The detection instrument 33 is installed on the fixed sealing plate 34 through a positioning groove. The detection mold cavity 22 containing the material 1 reaches the leak detection assembly station under the action of the annular conveying assembly. The leak detection assembly comprises the standard mold cavity 32. The standard mold cavity 32 contains the standard material 1 with good quality and no leakage. When the detection mold cavity 22 containing the material 1 reaches the leak detection assembly, the detection mold cavity 22 and the standard mold cavity 32 are sealed and vacuumized. The pressure data of the detection mold cavity 22 and the standard mold cavity 32 are measured by the detection instrument 33 and compared. If the data are the same, it means that the detection material 1 is qualified. If the data are different, it means that the material 1 in the detection mold cavity 22 has a leak. In addition, in order to improve the detection rate, a plurality of standard mold cavities 32 and detection instruments 33 matched therewith are arranged in the leak detection assembly. In this way, a plurality of materials 1 can be detected at the same time, and the detection efficiency is effectively improved.

[0049] Specifically, the material 1 passes through the feeding device 01 and is transported to the detection mold cavity 22 of the ring-shaped conveying assembly. The detection mold cavity 22 is installed on the ring-shaped synchronous belt 21, and the ring-shaped synchronous belt 21 transports the material 1 forward under the action of the servo motor 23. When the detection mold cavity 22 containing the material 1 is transported to the leak detection assembly, the detection mold cavity 22 is sealed under the action of the fixed sealing plate 34 and the movable sealing plate 35, and the standard mold cavity 32 of the leak detection assembly is also sealed. The detection instrument 33 installed on the fixed sealing plate 34 simultaneously performs vacuumizing, pressure maintaining and testing, and compares the data of the detection mold cavity 22 and the standard mold cavity 32. Since the standard material 1 is placed in the standard mold cavity 32, when the data of the two is different, it indicates that the material 1 in the detection mold cavity 22 has a leakage. The detection mold cavity 22 that has been detected continues to be transported forward under the action of the conveying assembly, and when it reaches the sorting assembly, the rejection mechanism rejects the unqualified material 1 from the detection mold cavity 22 and collects it through the collecting mechanism. Finally, the remaining detection mold cavity 22 containing the qualified material 1 is transported out through the discharging device 02.

[0050] As preferred, the feeding device 01 comprises a feeding belt conveyor 011, a feeding support assembly, a feeding track assembly, a feeding material collecting frame 014, a feeding conveying assembly and a feeding bottle pushing assembly 016. The feeding support assembly is arranged on the feeding belt conveyor 011, the feeding track assembly is hoisted on the feeding support assembly, the feeding material collecting frame 014 is arranged at the end of the feeding belt conveyor 011 along the conveying direction of the feeding belt conveyor 011, the feeding conveying assembly is arranged on the feeding material collecting frame 014 and is used for conveying the material 1 conveyed in the feeding track assembly to the detection mold cavity 22, and the feeding bottle pushing assembly 016 is arranged on the feeding material collecting frame 014 and is used for pushing the material 1 in the feeding conveying assembly to the detection mold cavity 22 for further processing. The discharging device 02 comprises a discharging belt conveyor 021, a discharging support assembly, a discharging track assembly, a discharging material collecting frame 024, a discharging conveying assembly, a first discharging bottle pushing assembly 026 and a second discharging bottle pushing assembly 027. The discharging support assembly is arranged on the discharging belt conveyor 021, the discharging track assembly is hoisted on the discharging support assembly, the discharging material collecting frame 024 is arranged at the end of the discharging belt conveyor 021 away from the conveying direction of the discharging belt conveyor 021, the discharging conveying assembly is arranged on the discharging material collecting frame 024 and is used for conveying the material 1 in the detection mold cavity 22, the first discharging bottle pushing assembly 026 is arranged on the discharging material collecting frame 024 and is used for pushing the material 1 in the detection mold cavity 22 to the discharging conveying assembly, and the second discharging bottle pushing assembly 027 is arranged at the connection between the discharging belt conveyor 021 and the discharging material collecting frame 024 and is used for pushing the material 1 in the discharging conveying assembly to the discharging track assembly.

[0051] Specifically, the feeding device 01 is used to receive the materials 1 transferred by the upper equipment and deliver them to the leak detection machine for further processing. The feeding rail assembly is hung on the feeding support assembly, which is arranged on the feeding belt conveyor 011. The feeding rail assembly does not directly contact the feeding belt conveyor 011 below. The feeding rail assembly provides a path for the delivery of the materials 1, so that the materials 1 can be delivered along the preset route. The delivery end of the feeding belt conveyor 011 is provided with a feeding material collecting frame 014, on which a feeding transport assembly is installed. The feeding transport assembly can transport the materials 1 delivered by the feeding belt conveyor 011 to the detection mold cavity 22, and push the materials 1 in the transport assembly to the detection mold cavity 22 through the feeding bottle pushing assembly 016 installed at the corresponding position.

[0052] The discharging process is opposite to the feeding process, and the discharging device 02 is similar to the feeding device 01. When the materials 1 in the detection mold cavity 22 are re-transported after detection, they are first pushed into the discharging transport assembly by the first discharging bottle pushing assembly 026 installed on the discharging material collecting frame 024. The discharging transport assembly can transport the materials 1 to the discharging belt conveyor 021, and push the materials 1 in the discharging transport assembly to the discharging rail assembly hung above the discharging belt conveyor 021 through the second discharging bottle pushing assembly 027, and then deliver them out under the action of the discharging belt conveyor 021.

[0053] That is, the feeding rail assembly and the discharging rail assembly are hung on the feeding support assembly and the discharging support assembly respectively, and do not contact the feeding belt conveyor 011 and the discharging belt conveyor 021, so as not to affect the operation of the belt conveyor. When the materials 1 are delivered to the feeding belt conveyor 011 and the discharging belt conveyor 021, they will be transported along the route formed by the feeding rail assembly and the discharging rail assembly. During feeding, when the materials 1 reach the feeding belt conveyor 011 along the preset route, the materials 1 will enter the feeding transport assembly under the action of the feeding belt conveyor 011, and be transported to the specified position by the feeding transport assembly, and then be pushed to the detection mold cavity 22 by the feeding bottle pushing assembly 016 for further processing. During discharging, the processed materials 1 will be transported to the discharging transport assembly from the detection mold cavity 22, and be pushed into the discharging transport assembly from the detection mold cavity 22 by the first discharging bottle pushing assembly 026, and then be transported to the discharging rail assembly by the discharging transport assembly, and then be pushed into the discharging rail assembly by the second discharging bottle pushing assembly 027, and then be delivered out under the action of the discharging belt conveyor 021.

[0054] In this way, the material 1 is conveyed to the feeding transport assembly, the feeding transport assembly transports the material 1 to the detection mold cavity 22, and the material 1 is pushed into the detection mold cavity 22 through the feeding bottle pushing assembly 016. When the material 1 completes the processing in the detection mold cavity 22, it is conveyed to the unloading transport assembly of the unloading device 02, the material 1 is pushed from the detection mold cavity 22 to the unloading transport assembly through the first unloading bottle pushing assembly 026, and is transported to the unloading track assembly. The material 1 is pushed into the unloading track through the second unloading bottle pushing assembly 027, and is unloaded under the action of the unloading belt conveyor 021.

[0056] Specifically, the driving pulley 24 is arranged on the feeding material collecting frame 014, and the driven pulley 25 is arranged on the unloading material collecting frame 024. The feeding material collecting frame 014 and the unloading material collecting frame 024 are respectively arranged at two ends of the leak detection frame 31 and the sorting frame 41, and form an integral whole in the order of the feeding material collecting frame 014, the leak detection frame 31, the sorting frame 41 and the unloading material collecting frame 024. The ring-shaped synchronous belt 21 is sleeved between the driving pulley 24 and the driven pulley 25, and flows in the direction of the length of the frame. In this way, the ring-shaped synchronous belt 21 can drive the detection mold cavity 22 installed thereon to circulate from the feeding device 01, pass through the leak detection assembly and the sorting assembly, and finally reach the unloading device 02.

[0057] It should be noted that the ring-shaped transport assembly has a long span, many detection mold cavities 22, large friction and load. The output pulley connected with the servo motor 23 and the driving pulley 24 adopt a specific transmission ratio to reduce the rotating speed and improve the output torque. Meanwhile, the ring-shaped synchronous belt 21 with reinforced tooth shape and high torque is adopted to meet the load demand, realize the accurate conveying and positioning of the detection mold cavity 22, and accurately dock the feeding and unloading, detection and sorting.

[0058] Preferably, the detection mold cavity 22 and the standard mold cavity 32 are symmetrically divided into two cavities along the opening direction of the cavities.

[0059] Specifically, the detection mold cavity 22 and the standard mold cavity 32 are both square cylindrical structures, and are open at both ends along the central axis. The detection mold cavity 22 and the standard mold cavity 32 are provided with a partition plate along the central axis in the cavity, so as to divide the cavity into left and right cavities.

[0060] In this way, two groups of materials 1 can be detected in one detection cavity 22 at the same time, and the detection efficiency of the leak detection assembly can be improved, thereby improving the production efficiency of the materials 1.
