[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] The core of this invention is to provide a conveying system that can improve product purification effect and enhance product quality.

[0050] For a specific embodiment of the conveying system provided by this utility model, please refer to the following: Figures 1 to 17 The system includes a detection device 3, a purging device 8, and a conveying device 4. The detection device 3 and the purging device 8 are arranged sequentially along a first direction X. The top of the conveying device 4 has a first conveying surface 42, on which multiple clamps 41 are sequentially arranged along the first direction X. Each clamp 41, driven by the first conveying surface 42, passes sequentially through the detection device 3 and the purging device 8. Specifically, the conveying direction of the first conveying surface 42 is parallel to the first direction X.

[0051] The purging device 8 includes an air blowing device 81 and an air suction device 84. The air blowing port of the air blowing device 81 and the air suction port of the air suction device 84 both face the clamp 41 that passes through the preset purging area.

[0052] It should be noted that product 10 can be a bag or a box. For the conveying system in this embodiment, for ease of explanation, it is used as a powder-liquid dual-chamber bag conveying system as an example. In this case, the conveyed product 10 is a powder-liquid dual-chamber bag, and correspondingly, the detection device is a light inspection device. In other embodiments, it can also be applied to the detection and conveying of other products 10 that require purification effects, as needed.

[0053] The powder-liquid dual-chamber bag is a fully enclosed infusion preparation structure. Drug powder and injectable solvent are placed in two chambers (liquid chamber 101 + powder chamber 102) within the same package using a partial welding technique. It can be opened by gently pressing before use. The production process of the powder-liquid dual-chamber bag mainly includes: bag making and sealing – light inspection of liquid chamber 101 – ventilation and sterilization – post-sterilization conveying – powder dispensing – light inspection before aluminum foil welding – aluminum foil welding – leak detection of powder chamber 102 and liquid chamber 101 – logistics packaging. In this embodiment, the conveying system is mainly used in the steps of light inspection before aluminum foil welding and transfer to the aluminum foil welding station.

[0054] Based on the setting of the purging device 8, after the detection device 3 detects the product 10, it can be placed on the clamp 41 for fixation. In this embodiment, manual conveying and fixing are adopted. Accordingly, the clamp 41 is a manual bag hanging structure, which can be used to horizontally fix the powder and liquid double chamber bag. In other embodiments, it can also be completed automatically by a robot arm. After the product 10 on the clamp 41 moves to the preset purging area under the drive of the first conveying surface 42, it is blown by the blowing device 81 and sucked by the suction device 84 to realize the purging and absorption of impurities on the surface of the product 10, which can improve the purification effect of the surface of the product 10 and improve the quality of the product 10.

[0055] Furthermore, such as Figure 2 As shown, the conveying system also includes a main frame 1, which is supported on the ground. The conveying device 4 is mounted on the main frame 1. The main frame 1 provides support, ensuring that the height of the first conveying surface meets the requirements for human operation. Alternatively, the main frame 1 can also be a height-adjustable structure.

[0056] Furthermore, in the purging device 8, such as Figure 13 and Figure 14 As shown, the blowing device 81 can specifically blow out ionized air. The blowing device 81 includes a blower rod 82, which is fixed to the main frame 1 by a blower rod mounting plate 83. The suction device 84 includes a collection tube 85, which is fixed to the main frame 1 by a collection tube fixing plate 86.

[0057] The first conveying surface 42 is provided with an air blowing device 81 and an air suction device 84 on its upper and lower sides, respectively. It should be noted that, in order for the air blowing device 81 and air suction device 84 below the first conveying surface 42 to blow a larger area, the product 10 can extend beyond the first conveying surface 42 on both sides in the second direction Y, where the second direction Y can correspond to the width direction of the first conveying surface 42, specifically perpendicular to the first direction X; and / or, the clamp 41 or the first conveying surface 42 is provided with ventilation holes, so that the air blowing device 81 and air suction device 84 below the first conveying surface 42 can blow at least a portion of the bottom surface area of ​​the product 10.

[0058] Among them, such as Figure 14As shown, the air outlet of the blowing device 81 and the air inlet of the suction device 84 are strip-shaped openings extending along the second direction Y, and respectively extend from both ends of the first conveying surface 42 in the second direction Y, so as to ensure the blowing capacity and area.

[0059] Furthermore, to improve feeding efficiency, the conveying system also includes a feeding device 2, and the feeding device 2 and the conveying device 4 are arranged sequentially along the second direction Y. The top of the feeding device 2 has a second conveying surface 24, which has the same conveying direction as the first conveying surface 42, and the second conveying surface 24 passes through the detection device 3.

[0060] Specifically, the product 10 is fed onto the second conveyor surface 24. Specifically, the second conveyor surface 24 is located in the conveyor belt, and the product 10 can be directly and freely placed onto the second conveyor surface 24; or, the second conveyor surface 24 includes a conveyor chain, and a feeding groove can be provided on the conveyor chain to place one or more products 10.

[0061] Based on the feeding device 2 in this embodiment, the feeding device 2 can feed materials to the detection device 3. Workers take materials from the second conveying surface 24 of the feeding device 2, place them on the detection device 3 for detection, and after detection, the workers place the product 10 onto the clamp 41 on the first conveying surface 42 for fixation. This facilitates material retrieval by workers in different positions. Of course, in other embodiments, loading carts can also be set up at various designated locations, for example, one loading cart near each worker, for each worker to retrieve materials.

[0062] In order to increase the production speed, for example, 3000 bags / hour, the conveying system is a mirror-symmetrical structure relative to a plane perpendicular to the second direction Y. For example, the symmetrical plane can be located in the middle of the feeding device 2. Relative to the symmetrical plane, the conveying device 4 and the detection device 3 are respectively arranged on both sides. In addition, the operation of the conveying system on both sides of the symmetrical plane can be carried out synchronously or asynchronously.

[0063] It should be noted that the first conveying surface 42 of the conveying device 4 and the second conveying surface 24 of the feeding device 2 can both be annular conveying mechanisms, including a top, a bottom, and two sides respectively connected to the top and bottom ends. The conveying direction of the first conveying surface 42 and the second conveying surface 24 mainly refers to the conveying direction of the areas where the first conveying surface 42 and the second conveying surface 24 are used for conveying the product 10, usually the top conveying direction, while the bottom is usually used for resetting and no longer holds the product 10.

[0064] The conveying device 4 includes a ring-shaped conveying body, such as a conveyor belt or conveyor chain, with a first conveying surface 42 being the portion of the conveying body that moves to the top. The conveying body can be driven by a conveyor motor 43. The feeding device 2 includes a ring-shaped feeding body, such as a conveyor belt or conveyor chain, with a second conveying surface 24 being the portion of the feeding body that moves to the top. The feeding body can be driven by a feeding motor 27. All conveyor belts can be belts. To ensure that the first conveying surface 42, where the conveying body moves to the top, has clamps 41 evenly distributed throughout the conveying body.

[0065] Furthermore, the testing device 3 includes a testing groove 33, the bottom of which has a testing opening 331. The testing opening 331 is located above the second conveying surface 24, and there is a material passage gap between them. At this time, the worker can directly take material from the second conveying surface 24, move it upwards through the testing opening 331 into the testing groove 33, and perform the testing operation, which is convenient. Of course, in other embodiments, a bottom sealing plate can be provided at the testing opening 331, allowing the worker to place the product 10 into the testing groove 33 from the side for testing.

[0066] In some embodiments, such as Figure 6 As shown, the detection device 3 is a lamp inspection device, with the detection slot 33 formed in the lamp inspection cover 31, and an inspection lamp can be installed in the detection slot 33. Under backlighting, impurities and foreign objects in the powder chamber of the powder-liquid dual-chamber bag can be clearly seen by the human eye or a magnifying glass, thereby preventing the missed detection of unqualified products and thus rejecting unqualified products.

[0067] In some embodiments, the assembly of the feeding device 2 and the detection device 3, such as Figures 2 to 4 , Figure 9 As shown, the starting section 25 of the feeding device 2 in its conveying direction is located on the side of the main frame 1 and is supported on the ground by the side legs 22. The remaining main feeding section 26 of the feeding device 2 is located directly above the main frame 1 and is supported on the main frame 1 by the support legs 21, for example, 5 support legs 21. The support legs 21 and the side legs 22 are all fixed to the side frame 23 of the feeding device 2. The second conveying surface 24 can move relative to the side frame 23 for conveying. At this time, the product 10 can be placed in the starting section 25 of the feeding device 2 for feeding.

[0068] In addition, the detection device 3 is suspended directly above the feeding device 2, specifically, as follows: Figure 6 As shown, the detection device 3 is fixed above the side frame 23 of the feeding device 2 by the support frame 32. There is a suitable material passage gap in the height direction between the detection device 3 and the main feeding section 26 of the second conveying surface 24, for example, about three times the thickness of the product 10, to allow workers to pick up materials from the main feeding section 26 and place them into the detection device 3, while ensuring that the product 10 can move smoothly on the second conveying surface 24 without interference from the detection device 3.

[0069] Furthermore, since the staff may take materials from the feeding device 2 and the feeding speed of the feeding device 2 may vary, the conveying system also includes a collection device to promptly collect products 10 that have not been taken away for inspection and then put them back on the second conveying surface 24 for feeding.

[0070] like Figure 2 and Figure 10 As shown, the collection device includes a guide channel 6 and a collection box 5. The guide channel 6 is located at the end of the second conveying surface 24 in the first direction X. The top port of the guide channel 6 is connected to the end of the second conveying surface 24. The collection box 5 is located below the bottom port of the guide channel 6. After the product 10 moves to the end of the second conveying surface 24, it can fall directly into the guide channel 6 and be guided and conveyed to the collection box 5 through the guide channel 6.

[0071] In some embodiments, in the first direction X, the end of the second conveying surface 24 is located between the detection device and the purging device. In this case, the feeding device 2 passes through the entire detection device 3, and the feeding device 2 is too long, which can avoid affecting production efficiency.

[0072] In some embodiments, such as Figure 10 As shown, the guide channel 6 includes multiple guide slides, which can be fixed to the main frame 1. Specifically, the guide slides include a first guide slide 61 and a second guide slide 62. The first guide slide 61 gradually slopes downwards along the first direction X, away from the end of the second conveying surface 24. The second guide slide 62 gradually slopes downwards along the first direction X, near the end of the second conveying surface 24. A portion of the second guide slide 62 is located below the first guide slide 61, while the remaining portion is at the same height as the first guide slide 61 and arranged sequentially along the first direction X, away from the end of the second conveying surface 24. When the product 10 conveyed by the second conveying surface 24 moves to the first guide slide 61 and slides down, it is blocked by the second guide slide 62 during its descent to prevent flying material. Upon reaching the second guide slide 62, it continues to slide down until it reaches the collection box 5. The collection box 5 is then pulled out from the main frame 1 to process the product 10 inside.

[0073] In some embodiments, such as Figure 10As shown, the bottom of the collection box 5 is equipped with rollers 51, for example, four, and the side of the collection box 5 has handles 52, allowing the staff to move the collection box 5 to a suitable position. Alternatively, the collection box 5 may have a driver to automate its operation. For example, it may periodically move to the collection position below the guide channel 6, and then periodically or quantitatively (e.g., by detecting the pressure on the bottom surface of the collection box 5) move to the set position at the feeding end (the starting end of the first direction X) of the feeding device 2, so that the staff can place the undetected product 10 from the collection box 5 back onto the second conveyor surface 24.

[0074] Furthermore, the conveying system also includes a manual controller 12 electrically connected to the conveying device 4. The manual controller 12 is used to control the start and / or stop of the first conveying surface 42. At this time, the start and / or stop of the first conveying surface 42 can be controlled at any time as needed via the manual controller 12. Specifically, the operation of the first conveying surface 42 can be controlled according to the progress of manual operation on the detection device 3.

[0075] For example, the manual controller 12 can only control the start of the first conveyor surface 42, while the stop of the first conveyor surface 42 can be automatically controlled by a pre-stored program. Optionally, the first conveyor surface 42 can start running for a set length or a set time and then automatically stop running. For example, when the first conveyor surface 42 stops running, during this process, after manually inspecting one or more products 10, the manual controller 12 can be operated to control the first conveyor surface 42 to start running a certain distance, such as the length of a set number (e.g., 3 or 6) of fixtures 41. The worker can then operate the manual controller 12 again, and the first conveyor surface 42 will start running again. At this time, the application of the manual controller 12 can prevent the first conveyor surface 42 from running idle, and when the first conveyor surface 42 is paused, the product 10 can be placed on the fixture 41, making the operation convenient.

[0076] In some embodiments, the manual controller 12 includes a touch-sensitive switch, allowing direct control of the first conveying surface 42 via touch, making operation convenient. In other embodiments, the manual controller 12 may also include buttons or knobs.

[0077] In some embodiments, such as Figure 2 As shown, along the first direction X, the detection device 3 sequentially includes multiple manual controllers 12, such as 3, 5, or 6. When at least two manual controllers 12 simultaneously receive a start signal or simultaneously receive a stop signal, they correspondingly control the first conveyor surface 42 to start or stop, which can improve operational safety and reduce the start-stop frequency of the first conveyor surface 42.

[0078] It should be noted that, in actual operation, the number of manual controllers 12 actually put into use, requiring simultaneous operation to control the start or stop of the first conveyor surface 42, can be set as needed. Specifically, all can be used, or only some can be used, and the number can be two or more. For example, the selection can be based on the number of workers; each worker can be assigned two manual controllers 12, controlled by both hands. In this case, when one person performs a detection operation, two manual controllers 12 are used; when two people perform a detection operation, four manual controllers 12 are used, and so on. Manual controllers 12 not in use are in a disabled state, for example, through power-off or short-circuit methods.

[0079] In addition, the number and location of the manual controllers 12 put into use can be set to be selectable as needed, for example, on the field control panel, in the background control system, or on the mobile terminal connected to the conveyor system.

[0080] Of course, in other embodiments, the start and stop control of the first conveyor surface 42 can be achieved by setting only one or only one manual controller 12. Alternatively, the start and stop of the first conveyor surface 42 can also be automatically controlled by a preset degree, such as timed control.

[0081] In some embodiments, such as Figure 9 As shown, a mounting bracket, specifically an inverted U-shaped frame, is also fixed on the main frame 1. The mounting bracket is located above the first conveying surface 42, which can pass through the lower channel of the mounting bracket. The manual controller 12 is located on the top surface of the mounting bracket. When the worker places the product 10 on the fixture 41, he can operate the manual controller 12 by raising his hand, which can prevent the worker from being injured by approaching the rotating first conveying surface 42.

[0082] In some embodiments, the main frame 1 is also provided with a handle 11 for workers to hold. Optionally, in the first direction X, a handle 11 is provided between two adjacent manual controllers 12. During the operation, the worker is positioned facing a handle 11 and can operate the manual controllers 12 on both sides of the handle 11.

[0083] Furthermore, the conveying system also includes a punching device 7. In the first direction X, the punching device 7 is located between the detection device 3 and the purging device 8. The punching device 7 includes a punching driver 72 and a punching die 73. The punching driver 72 drives the punching die 73 to reciprocate along a preset punching direction, specifically, to extend and retract along the second direction Y. When applied to the processing of a powder-liquid double-chamber bag, the powder chamber 102 and the liquid chamber 101 of the powder-liquid double-chamber bag are arranged sequentially along the second direction Y. A small hole is punched in the welding area in the middle of the tail of the powder-liquid double-chamber bag, specifically in the edge area of ​​the powder chamber 102 away from the liquid chamber 101. This facilitates the flow of inert gas in the hollow portion between the upper and lower layers and the aluminum film of the powder-liquid double-chamber bag under the coverage of the upper and lower aluminum films, ensuring the residual oxygen content.

[0084] In some embodiments, such as Figure 11 and Figure 12 As shown, the punching device 7 includes a fixed plate 71, a punching driver 72 mounted on the fixed plate 71, and a punching die 73 connected to the output end of the punching driver 72. The fixed plate 71 is fixed to the main frame 1. The punching die 73 has a punch that can move up and down, specifically driven by a cylinder. The punching driver 72 can be a pneumatic cylinder or a hydraulic cylinder. Driven by the punching driver 72, the punching die 73 can move along the second direction Y. Specifically, the first conveying surface 42 stops moving, and a clamp 41 aligns with the punching die 73 in the second direction Y. By extending to a suitable position, such as the positioning groove on the punching die 73 clamping the edge of the product 10, the punch punches a vent hole into the clamped edge of the product. Through the upward movement of the punch and the retraction movement of the punching die 73, the punching device 7 moves away from the product 10, preventing the movement of the clamp 41 in the first direction X from impacting the punching die 73.

[0085] In some embodiments, such as Figure 11 As shown, a limiting plate 74 is provided on the fixed plate 71, and a baffle 75 is fixed to the output end of the punching driver 72. The output end of the punching driver 72 can extend and move until the baffle 75 impacts the limiting plate 74 to limit the length and position of the punch. The limiting plate 74 can be bolted to the fixed plate 71, and its connection position can be adjustable. For example, the limiting plate 74 can be bolted to an elongated hole extending along the second direction Y on the fixed plate 71.

[0086] Furthermore, such as Figure 17As shown, the conveying system also includes a feeding device 9. The detection device 3, the blowing device 8, and the feeding device 9 are arranged sequentially along the first direction X. The feeding device 9 includes a feeding body 95 and a first picking structure 96 and a second picking structure 94 respectively connected to the feeding body 95. The first picking structure 96 and the second picking structure 94 are arranged sequentially along a preset feeding direction and can both be raised and lowered. The feeding body 95 can move along the preset feeding direction, which is specifically the second direction Y. At this time, the feeding device 9 can pick up the material from the clamp 41, and after picking up the material, it can smoothly drive the product 10 away from the first conveying surface 42.

[0087] In some embodiments, the first material handling structure 96 and the second material handling structure 94 are respectively adapted to the shape of the product 10. For example, the first material handling structure 96 is a gripper 92, specifically a pneumatic gripper, and the second material handling structure 94 is a positioning sleeve 91, specifically a positioning female pin, used to cooperate with the positioning pin 411 on the fixture 41, specifically they can be sleeved together. The product 10 is provided with a bag hanging hole. On the fixture 41, it is sleeved in the positioning pin 411. After the bag hanging hole undergoes slight deformation and passes through the locking block at the bottom of the positioning sleeve 91, it resets and overlaps on the top step surface of the locking block, thereby fixing the bag hanging hole on the positioning sleeve 91.

[0088] In some embodiments, such as Figure 17 As shown, to achieve automatic feeding of the clamp 41 to the feeding device 9, the feeding body 95 includes a first lifting part 93, the bottom output end of which is connected to both a first picking structure 96 and a second picking structure 94. A second lifting part 13 and a third lifting part 14 are also provided on the main frame 1, distributed along the second direction Y on both sides of the first conveying surface 42. A first push plate 15 is provided at the top of the second lifting part 13 for pushing the product upwards towards the first picking structure 96. A second push plate 16 is provided at the top of the third lifting part 14 for pushing the product upwards towards the second picking structure 94. The first lifting part 93, the second lifting part 13, and the third lifting part 14 can be either pneumatic cylinders or hydraulic cylinders.

[0089] During use, when product 10 is transferred to the lower bag station, the first lifting part 93 drives the first picking structure 96 and the second picking structure 94 to move downward. When the first picking structure 96 is a gripper 92, the gripper 92 descends in an open state, but maintains a certain distance from the fixture 41. When the second picking structure 94 is a positioning pin, it contacts the positioning pin 411. The second lifting part 13 drives the first push plate 15 to push upward. For example, there are two first push plates 15, which respectively push the pipe opening on one side of the liquid cavity 101 of product 10 and the liquid cavity 101 part, pushing the liquid cavity side of product 10 out of the fixture 41, and enabling the gripper 92 to clamp one end of product 10. The third lifting part 14 drives the second push plate 16 to push the bag hanging hole on the edge of the powder cavity 102 of product 10 out of the positioning pin and push it onto the positioning pin to lock it.

[0090] In this embodiment, the conveying system, in one specific implementation, is applied to a powder-liquid dual-chamber bag, specifically a medicine bag, and its working principle includes:

[0091] based on Figure 1 After the powder is filled in the powder dispensing machine, the powder-liquid dual-chamber bag is conveyed to the feeding device 2 via a conveyor belt. The second conveying surface 42 of the feeding device 2 moves at a uniform speed from right to left at a specified speed, bringing the bag into the area below the detection device 3. At this time, a manual person takes a bag off the second conveying surface 42 and inspects it against the light inspection cover 31 of the detection device 3 to check if there are any foreign objects in the powder cavity. If there are foreign objects, it is judged as unqualified. Another bag is then taken to check if there are any foreign objects in the powder cavity. This process continues until there are no foreign objects, at which point the bag is judged as qualified. The bag without foreign objects is then manually placed into the clamp 41 for hanging. Three clamps 41 are grouped together and can be fixed as one unit. The conveying device includes five areas where bags can be hung. Three workers randomly select one detection area. In this detection area, one or more workers can control one or more manual controllers 12. For example, on a clamp group, the first person hangs a medicine bag on a clamp 41, the second person hangs a medicine bag on an empty clamp 41, and the third person does the same. Then the workers put their hands on the manual controllers 12 on the left and right sides of the clamp group respectively, and then the first conveying surface 42 of the conveying device can rotate once, and so on.

[0092] After the third person hangs the medicine bags, three medicine bags are hung on this set of clamps 41. Then they enter the punching device 7, and the punching mold 73 is pushed out to punch a small hole in the welding area in the middle of the tail of the medicine bag. This facilitates the flow of inert gas in the hollow part between the upper and lower layers of the medicine bag and the aluminum film under the cover of the upper and lower layers of aluminum film, ensuring the residual oxygen content.

[0093] The first transmission surface 42 further conveys the medicine bag, which then enters the blowing device 8 to clean the dust and hair on the medicine bag, thereby improving product quality.

[0094] The first transmission surface 42 continues to convey the medicine bags. This group of medicine bags arrives at the transfer unloading station. The first lifting unit 93 drives the pneumatic gripper and positioning pin downwards. The pneumatic gripper descends in an open state, but maintains a certain distance from the clamp. The positioning pin contacts the positioning pin. The second lifting unit 13 drives the first push plate 15 to push the medicine bag opening tube out of the clamp. The third lifting unit 14 drives the second push plate 16 to push the medicine bag tail off the positioning pin and onto the positioning pin. The second lifting unit 13 and the third lifting unit 14 simultaneously reset. The gripper clamps the medicine bag opening tube, and the positioning pin passes through the bag hanging hole. Then, the unloading device 9 moves along the second direction Y, and the medicine bag enters the subsequent process flow. After the medicine bag leaves the clamp 41, the first transmission surface 42 can continue to operate.

[0095] Additionally, on the second conveyor surface 24 of the feeding device 2, since it moves at a uniform speed from right to left at a specified speed, some medicine bags may not be removed in time for light inspection at the detection device 3 and will fall into the conveyor device 4. The medicine bags will slide into the collection box 5 according to the guidance of the bag guide slide, and then the collection box 5 will be manually pulled out of the equipment. When there are fewer medicine bags in the feeding device 2, these medicine bags will be light inspected and hung up.

[0096] The conveying system in this embodiment, when applied to the bag inspection and conveying process, can solve the problems of easy bag handling failure, multiple equipment, high cost, and low efficiency of automatic light inspection and transfer. The entire production line operates at a fast speed and can effectively connect with upstream and downstream equipment to realize the integrated light inspection function of the entire production line, thereby improving production efficiency. The manual bag hanging method ensures stable operation. The traditional mechanical structure design results in lower cost and higher operating efficiency. Each person performs one light inspection and hangs one medicine bag at a time, reducing labor intensity. The addition of a manual controller 12 as a safety switch ensures high safety.

[0097] The above-described conveying system can be applied to the following conveying methods. Specifically, the conveying method can apply the conveying system provided in any of the above embodiments, and the beneficial effects can be referred to the above embodiments accordingly.

[0098] The conveying method specifically includes the following steps:

[0099] S1: After receiving the start signal from the conveying device 4, control the first conveying surface 42 to convey a preset length and then pause;

[0100] S2: During the pause, control the purging device 8 to start.

[0101] In addition, the punching device 7 and the unloading device 9 can also be started during this pause. With the restart of the conveying device 4, the punching device 7, the blowing device 8, and the unloading device 9 can also stop operating.

[0102] Specifically, in this embodiment, the purging device 8 is only started during the pause of the first conveying surface 42, and is not started during operation; in other embodiments, the purging device 8 may also be always in the started state, regardless of whether the first conveying surface 42 is running or not.
