It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device, are only exemplary and should not constitute any limitation on the present application.

[0040] As used herein, "a number of" means two or more (including two).

[0041] In the medicine filling production line, the medicine bottle is conveyed to the filling station by the conveying belt, and the filling needle needs to be accurately inserted into the bottle mouth to complete the filling. However, the medicine bottle mainly exists in the following three postures during the conveying process: upright state (bottle mouth upward, vertical standing), side-down state (bottle body horizontal, bottle mouth sideways) and overturning state (bottle mouth downward, vertical standing), only the medicine bottle in the upright state can be normally filled, and the medicine bottle in the side-down state and the overturning state cannot be filled, in addition, the medicine bottle in the overturning state will cause the filling needle to be bent, damaged or broken when the filling needle moves downward to fill and collides with the bottle bottom.

[0042] The filling production line of the related art is usually equipped with a side-down medicine bottle screening device, which uses mechanical baffles, photoelectric sensors or visual detection to identify and reject the horizontal state medicine bottle. However, the overturning state medicine bottle is difficult to be accurately identified by the screening device in the related art because the bottle body still remains vertical and is similar to the normal medicine bottle in height and profile, resulting in that the overturning state medicine bottle enters the filling station, causing the filling needle to be bent by colliding with the bottle bottom, affecting the production efficiency and the equipment life.

[0043] At present, the related art mainly realizes the detection of the side-down medicine bottle based on the sensing module such as the photoelectric sensor, which installs the opposite-acting photoelectric sensor on both sides of the conveying belt to judge whether the medicine bottle is side-down (the horizontal state medicine bottle blocks the light beam abnormally) by detecting the height change of the medicine bottle. The above scheme can only identify the side-down medicine bottle, and has limitations because the photoelectric sensor cannot distinguish the upright height of the overturning medicine bottle from that of the upright state medicine bottle. In addition, part of the schemes in the related art use baffles to correct the posture of the medicine bottle, but the overturning medicine bottle may be misjudged as the upright state, which cannot adapt to the requirements of different bottle types or high-speed production lines.

[0044] Embodiments of the present application aim at the above-mentioned defects of the related art, and propose an automatic overturning screening device for upside-down bottles, which forcibly converts the overturning medicine bottle into the horizontal state through a poking device, and then realizes full coverage detection of the conveying state of the medicine bottle to be filled by combining with the subsequent use of existing visual or depth sensors, solves the problem that the overturning medicine bottle is difficult to identify, avoids conveying the abnormal medicine bottle to the filling station, guarantees continuous production, thereby improving the production efficiency and the yield, and ensuring the stable output of qualified products.

[0045] Please refer to Figure 1 and Figure 2 , Figure 1 is a top view of the automatic overturning screening device for upside-down bottles provided by the present application, Figure 2 is a front view of the automatic overturning screening device for upside-down bottles provided by some embodiments of the present application.

[0046] The application provides an automatic overturning and screening device for bottles, which is suitable for screening of bottles 5 to be filled with liquid medicine and mainly comprises a conveying device 1, a poking device 2 and a limiting piece 3. The conveying device 1 is used for conveying the bottles 5 to be filled with liquid medicine. The poking device 2 is fixedly installed with the conveying device 1, blocks the passage of the bottles 5 in an overturned state through the poking device 2, and converts the bottles 5 in the overturned state into a horizontal state. The limiting piece 3 is fixedly connected with the conveying device 1 and is distributed on both sides above the conveying device 1 along a first direction X. The limiting piece 3 is used for limiting the displacement of the bottles 5 in the first direction X, so that the bottles 5 are transmitted along a second direction Y. The limiting piece 3 is provided with a guide structure 31 arranged on the front side of the poking device 2 along the transmission direction, which is used for guiding the bottles 5 in the horizontal state to be separated from the conveying device 1.

[0047] The conveying device 1 is a transmission platform of the bottles 5, which can continuously convey the bottles 5 to be filled with liquid medicine. The conveying device 1 can adopt the form of a conveyor belt, a conveyor chain or the like to ensure that the bottles 5 move along the transmission direction.

[0048] The poking device 2 is fixed above the conveying device 1, which can be a baffle, a poking wheel, a mechanical arm or the like. The poking device 2 can block the passage of the bottles 5 in the overturned state. When the overturned bottles 5 pass through the poking device 2, the poking device 2 comes into contact with the bottom of the bottles 5. The overturned bottles 5 are intercepted and fall onto the conveying device 1, so that the overturned bottles are adjusted to the horizontal state and then continue to be conveyed to the second direction Y by the conveying device 1.

[0049] Continuing to refer to Figure 1 The limiting piece 3 extends along the second direction Y. Optionally, the limiting piece 3 is two guide rails or two guide plates or two guardrails. The limiting piece 3 adopts a double guardrail structure to provide accurate guidance for the transmission of the bottles 5, so as to ensure the straight-line transmission of the bottles 5. Optionally, the limiting piece 3 is arranged in the same length as the conveying device 1. Two limiting pieces 3 are respectively fixed on both sides of the conveying device 1 along the first direction X. Taking the conveying device 1 as an example, the limiting piece 3 is fixed on the two side supports of the conveyor belt. The height difference between the limiting piece 3 and the conveying device 1 is slightly greater than the maximum diameter of the bottles 5. The width of the limiting piece 3 is slightly greater than the diameter of the bottles 5, so as to effectively block the bottles 5. A conveying space is formed between the limiting piece 3 and the conveying device 1 to ensure the stable conveying of the bottles 5 along the transmission direction.

[0050] The stopper 3 is equipped with a guide structure 31, located behind the shifting mechanism 2 along the conveying direction, forming a continuous guide path to prevent bottle collisions or jams. The guide structure 31 is connected to the conveying mechanism 1 and guides horizontal bottles 5 out of the conveying mechanism 1 while ensuring that upright bottles 5 can continue to be transported smoothly through the guide structure 31. As the bottles 5 are conveyed by the conveying mechanism 1, the shifting mechanism 2 intercepts the inverted bottles 5 and corrects them to a horizontal position, where they are then guided out in an orderly manner by the guide structure 31 of the stopper 3.

[0051] The embodiment of the present application provides an automatic flipping and screening device for inverted bottles. The medicine bottles 5 in the flipped state can be identified by the toggle device 2 and blocked and intercepted. The intercepted medicine bottles 5 fall on the conveying device 1. When passing through the guide structure 31, the medicine bottles 5 that fall to a horizontal state are removed and output, and the remaining upright medicine bottles 5 continue to be conveyed to ensure that only qualified medicine bottles 5 enter the filling position, thereby realizing automatic identification of flipped medicine bottles, reducing manual intervention, thereby improving the filling success rate, saving raw materials, and avoiding damage to the filling needle due to collision with the bottom of the bottle, or frequent shutdowns caused by leakage of liquid medicine. In addition, the toggle device 2 and the limiter 3 in the present application are integrated into the conveying device 1, with a compact structure, small space occupation, adaptability to existing production lines, small modifications, high reliability, and mechanical correction without the need for complex sensors, low failure rate, and easy maintenance.

[0052] like Figure 3 As shown, combined with Figure 2 In a specific embodiment, the toggle device 2 includes a fixing member 21 and a toggle member 22. The fixing member 21 is a rigid connecting member extending along the third direction Z (i.e., the vertical direction). The bottom fixed end of the fixing member 21 is fixedly connected to the conveying device 1 (such as a conveyor belt frame) to ensure overall stability. The top of the fixing member 21 is fixedly connected or movably connected to the toggle member 22.

[0053] The toggle member 22 is arranged on the upper part of the fixing member 21. The toggle member 22 is arranged on one side of the conveying device 1. The toggle member 22 is provided with a toggle part 221. The toggle part 221 is arranged above the conveying device 1. The toggle part 221 acts on the bottom of the medicine bottle 5 in the flipped state, to toggle the bottom of the bottle. The bottom of the medicine bottle 5 in the flipped state contacts the conveying device 1 and is conveyed forward. The bottom of the bottle at the top is toggled by the toggle part 221, so that the medicine bottle 5 becomes unstable and falls onto the conveying device 1. In this way, the medicine bottle 5 in the flipped state is converted to a horizontal state and continues to be conveyed forward through the conveying device 1.

[0054] The poking part 221 in the embodiment can precisely interfere with the conveying state of the inverted medicine bottle 5, quickly convert the inverted medicine bottle 5 into a horizontal state, and then remove the medicine bottle 5 from the conveying line, so that the state of the medicine bottle 5 is automatically screened and corrected through mechanical linkage, the qualified rate before filling is significantly improved, and the high-speed production line in the pharmaceutical, food and other industries is suitable.

[0055] The poking member 22 in the embodiment can be provided as a structure with adjustable extension length to adapt to medicine bottles 5 of different sizes.

[0056] Specifically, in the first specific embodiment, the poking part 221 is fixedly connected to the side of the poking member 22 away from the fixing member 21, the outer periphery of the poking member 22 is provided with a first external thread, the fixing member 21 is provided with a first internal thread, and the poking member 22 and the fixing member 21 are connected through the first external thread and the first internal thread, allowing only the poking member 22 to move in the first direction X, thereby adjusting the position of the poking part 221, with high adjustment accuracy, self-locking of the threaded connection, and arbitrary locking of the adjustment position, thereby meeting the long-distance adjustment requirement.

[0057] In the second specific embodiment, the position of the poking part 221 in the first direction X is adjustable. Specifically, one of the poking part 221 and the poking member 22 is provided with a second external thread, and the other is provided with a second internal thread. The poking part 221 and the poking member 22 are connected through the second external thread and the second internal thread to form a screw pair, and the rotational motion is converted into linear movement of the poking part 221 through threaded connection. When the poking part 221 is rotated, the poking part 221 moves in the first direction X towards or away from the direction of the medicine bottle 5, thereby adjusting the position of the poking part 221 to meet the position adjustment requirement of the poking part 221. Compared with the first specific embodiment, the present embodiment is suitable for fine adjustment of the position of the poking part 221. Of course, the combination of the above two threaded connections can be used to realize long-distance and large-range coarse adjustment and small-distance fine adjustment of the poking part 221.

[0058] Further, a first adjustment part can be arranged on the fixing member 21, and the first adjustment part is distributed in the third direction Z. The poking device 2 further comprises a first locking member, such as a bolt and a nut, a screw, a pin, a clamping mechanism, etc. The first locking member is arranged on the first adjustment part, and the first locking member connects and fixes the fixing member 21 and the conveying device 1, and realizes locking and fixing of the two.

[0059] The first adjusting part can be a long strip-shaped hole, a sliding groove or a guide rail structure, which can provide a space for position adjustment. The first locking member penetrates or is embedded into the first adjusting part of the fixing member 21 and is connected with the corresponding interface (such as a long strip-shaped hole, a threaded hole, a guide member) of the conveying device 1. When the first locking member is in a loosening state, the fixing member 21 can move along the first adjusting part to adjust the position with the conveying device 1. After the position adjustment is completed, the fixing member 21 is rigidly connected with the conveying device 1 by locking with the first locking member, thereby forming a stable structure. Therefore, by cooperation of the first adjusting part and the first locking member, the height adjustment of the fixing member 21 and the poking member 22 connected thereto is realized, which is suitable for different sizes of the medicine bottle 5.

[0060] Further, the fixing member 21 is further provided with a second adjusting part in the third direction Z. The second adjusting part is arranged on the upper side of the first adjusting part and can adjust the displacement of the poking member 22 in the third direction Z. The poking device 2 further comprises a second locking member. The poking member 22 is slidingly connected to the second adjusting part, and the second locking member is arranged on the second adjusting part. The second locking member is used to lock and connect the poking member 22 and the fixing member 21. In this way, by cooperation of the second adjusting part and the second locking member, the height adjustment of the poking member 22 is realized. On the basis of the above-mentioned height-adjustable scheme of the fixing member 21, the height adjustment range is further increased, and the adjustment is more flexible and convenient.

[0061] In order to reduce the risk of scratching the surface of the medicine bottle 5, the contact surface of the poking part 221 can be made of flexible material or arc-shaped transition. A protective structure can also be arranged on the poking part 221. The protective structure can be bonded, detachably fastened or sleeved on the outer peripheral surface of the poking part 221. The protective structure can be made of soft material such as rubber or silicone, so as to avoid scratches on the surface of the medicine bottle 5 and protect the integrity of the medicine bottle 5.

[0062] Continuing to refer to Figure 1 In a specific embodiment, the guide structure 31 can include a first guide part and a second guide part. The first guide part and the second guide part are respectively formed by the two limiting members 3 protruding in the direction of the first direction X and close to the containing bin 4. The first guide part and the second guide part can be arc-shaped or U-shaped. The first guide part and the second guide part form a guide channel for the medicine bottle 5 in the upright state to pass through. The second guide part close to the containing bin 4 forms a blanking gap between the second guide part and the conveying device 1, so that the medicine bottle 5 in the horizontal state can pass through the blanking gap and fall into the containing bin 4. The inverted bottle automatic overturning and screening device further comprises a containing bin 4 arranged outside the guide structure 31 and capable of containing the medicine bottle 5 discharged from the conveying device 1.

[0063] Optionally, the first guide part and the second guide part are both arc-shaped structures, and the curvatures of the first guide part and the second guide part are the same and face the same direction. Thus, the first guide part, the second guide part and the conveying device 1 form a conveying channel. By arranging the first guide part and the second guide part as the same arc-shaped structures, the machining can be facilitated.

[0064] Optionally, the maximum distance between the second guide part near the side of the containing bin 4 and the conveying device 1 in the first direction X is less than the diameter of the medicine bottle 5, corresponding to Figure 1 , a blanking gap is formed between the second guide part and the conveying device 1, and the maximum horizontal distance a between the side wall of the conveying device 1 near the side of the second guide part and the second guide part (i.e. the maximum size of the blanking gap) should be less than the diameter of the medicine bottle 5, so that the medicine bottle 5 in the horizontal state can pass through the blanking gap to separate from the conveying device 1 and enter the containing bin 4, while the medicine bottle 5 in the vertical state can pass normally, thereby achieving the screening of the medicine bottle 5 in the horizontal state. In this way, the medicine bottle 5 in the horizontal state (including the converted overturned medicine bottle) is squeezed out of the conveying path by the curved structure of the limiting part 3, and only the qualified medicine bottle 5 in the vertical state is reserved.

[0065] When the device is started, the conveying device 1 transports the medicine bottle 5 for filling, and the medicine bottle 5 moves to the side of the poking part, and the bottle opening of the medicine bottle 5 in the vertical state does not contact the poking part. At the same time, since the distance between the farthest point of the bending part of the limiting part 3 and the conveying device 1 (i.e. the maximum size of the blanking gap) is less than the diameter of the medicine bottle 5, the medicine bottle 5 in the vertical state does not separate from the conveying device 1 at the bending part of the guide structure 31. When the overturned medicine bottle 5 moves to the side of the poking part 22, the bottom of the medicine bottle 5 contacts the poking part 22 and is poked by the poking part 22 to the horizontal state. The medicine bottle 5 in the horizontal state continues to move forward to the guide channel formed by the first guide part and the second guide part. Since the diameter of the medicine bottle 5 is less than the distance between the limiting part 3 and the conveying device 1, the medicine bottle 5 in the horizontal state directly separates from the conveying device 1 and enters the containing bin 4, thereby achieving the screening of the medicine bottle 5. The medicine bottle 5 in the vertical state is transported by the conveying device 1 to the predetermined position for filling.

[0066] In summary, the overturned bottle automatic overturning and screening device provided by the present application completely removes the overturned medicine bottle and other abnormal medicine bottles that are missed by the traditional method, ensures that all medicine bottles 5 are transported to the filling position with the bottle opening facing upward, ensures that the filling needle is accurately inserted, realizes zero collision risk, prolongs the service life of the filling needle, reduces downtime maintenance time and cost, avoids liquid overflow and pollution of the device or surrounding medicine bottles 5 when the overturned and sideways overturned medicine bottles 5 are filled, and meets the clean production requirements.

[0067] It should be noted that the first direction X, the second direction Y and the third direction Z in the present application are perpendicular to each other. The first direction can be the X direction in Figure 1 and Figure 3 , the second direction is perpendicular to the first direction X, for example, it can be the Y direction in Figure 1 and Figure 2 , and the third direction can be the Z direction in Figure 2 and Figure 3 .

In this paper, specific examples are used to explain the principles and implementation methods of the present application. The above description of the examples is only used to help understand the method of the present application and its core idea. It should be pointed out that for ordinary skilled persons in the technical field, some improvements and modifications can be made to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the present application.
