Description

Technical Field

[0001] The utility model relates to the technical field of soft bag detection, in particular to a quality detection device for infusion soft bags. Background Technique

[0002] A soft bag is an infusion bag. To ensure infusion safety, it is necessary to detect foreign matters in the liquid in the bag and detect the appearance of the bag. Due to the plastic material of the infusion soft bag, its processing technology and shape, it is very easy for foreign matters to adhere to the infusion soft bag. At present, manual lamp inspection is usually used to detect soft bags, but the manual inspection has low efficiency, the personnel are prone to fatigue, and the quality of the soft bags is uncontrollable; there is also a form of automatically detecting soft bags by using a soft bag lamp inspection machine, but a single detection background is likely to cause missed detection. For example, foreign matters with colors similar to the background are difficult to be detected. Therefore, there is an urgent need for a device that can detect the quality of infusion soft bags, which can not only improve the detection efficiency but also ensure the detection accuracy. Content of the Utility Model

[0003] The purpose of the utility model is to provide a quality detection device for infusion soft bags, which can solve the technical problems mentioned in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A quality detection device for infusion soft bags, including: at least two inclined conveyor lines, the shorter side of the conveyor line forms a predetermined angle with the horizontal plane, and a detection station is provided on the conveyor line. Adjacent conveyor lines are set with background colors of different depths; it also includes a lamp inspection part corresponding to the detection station, and the lamp inspection part is used for lamp inspection of infusion soft bags.

[0005] In an embodiment, the inclination angle α of the conveyor line is set between 10° and 45°. This angle can not only ensure the stable placement of the infusion soft bag but also make the liquid in the bag concentrate and fill in one direction.

[0006] In an embodiment, the lamp inspection part includes a first lamp inspection part and a second lamp inspection part. The first lamp inspection part corresponds to the detection station of the conveyor line, and the second lamp inspection part corresponds to the connection gap position between two adjacent conveyor lines. The second lamp inspection part is used to detect the infusion soft bag at the middle gap where two conveyor lines are connected.

[0007] In an embodiment, the lamp inspection part includes a shooting piece and a light source. The light source of the second lamp inspection part is placed on the front and / or back of the conveyor line, and the shooting piece of the second lamp inspection part is placed on the front and / or back of the conveyor line. Different combination forms correspond to different shooting focuses.

[0008] In one embodiment, two adjacent conveying line bodies form a conveying line body group. The infusion soft bag quality detection device further includes an attitude adjustment part arranged between two adjacent conveying line body groups. The attitude adjustment part is used to adjust the attitude of the infusion soft bag, so that the infusion soft bag and the liquid inside it shake during the conveying process, avoiding foreign objects from adhering to the side of the soft bag, which is beneficial to the identification of foreign objects.

[0009] In one embodiment, the inclination angles of two adjacent conveying line body groups are different. During the transfer of the infusion soft bag between the two conveying line body groups, its attitude will change with the inclination angle.

[0010] In one embodiment, among two adjacent conveying line body groups, the inclination angle of one conveying line body group is an acute angle, and the inclination angle of the other conveying line body group is an obtuse angle. This setting can make the liquid in the infusion soft bag tilt and fill in two directions, with a large shaking amplitude, avoiding foreign objects from adhering to difficult-to-identify positions such as the side of the soft bag.

[0011] In one embodiment, the infusion soft bag quality detection device further includes a rejection conveyor connected to the end conveying line body. The rejection conveyor can swing so as to be connected to the qualified product conveying line and the unqualified product conveying line respectively.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The infusion soft bag quality detection device provided by the present utility model inclines the conveying line body, so that the liquid in the infusion soft bag is concentrated on one side, which is beneficial to fully detecting foreign objects in the liquid. At the same time, it can also reduce the shaking of the liquid in the bag, further ensuring the detection accuracy. On the other hand, the inclination setting method of the shorter side of the conveying line body has better stability compared with the inclination setting method of the longer side. Any abnormal situation such as dropping of an infusion soft bag will not affect other infusion soft bags, and this inclination setting method can also accommodate more infusion soft bags, effectively improving the detection efficiency;

[0014] 2. By setting two adjacent conveying line bodies to two background colors of white and black respectively, the appearance and foreign objects of the infusion soft bag can be detected more accurately;

[0015] 3. By setting the second lamp inspection part and the third lamp inspection part corresponding to the connection position of two adjacent conveying line bodies, soft bag images in bright field, dark field and gap positions can be obtained simultaneously, making the detection result more accurate;

[0016] 4. By providing an attitude adjustment part between two adjacent conveyor line groups, the attitude of the infusion soft bag can be adjusted, causing the infusion soft bag and the liquid inside it to shake during the conveying process, avoiding foreign objects from adhering to the side of the soft bag, which is beneficial to the identification of foreign objects; at the same time, the attitude adjustment part is also used to connect the two conveyor line groups to enable the smooth transition of the infusion soft bag.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0030] Embodiment 1

[0031] First, refer to Figure 1 and Figure 2 , in the first embodiment, the infusion soft bag quality detection device includes at least two conveying line bodies 1 for conveying the infusion soft bags. A detection station 2 is provided on the conveying line body 1. The infusion soft bag quality detection device further includes a lamp inspection unit corresponding to the detection station 2 for lamp inspection of the infusion soft bags.

[0032] During operation, a number of infusion soft bags are sequentially and orderly placed on the conveying line body 1. The conveying line body 1 drives the infusion soft bags to move forward. When they move forward to the detection station 2, the lamp inspection unit performs quality detection on the infusion soft bags. Exemplarily, the lamp inspection unit can adopt a shooting member 5 and a light source 6. The two cooperate to collect pictures of the infusion soft bags, and perform quality detection and analysis on the infusion soft bags according to the collected pictures. For example: performing appearance detection on the infusion soft bags or detecting foreign objects in the infusion soft bags.

[0033] Specifically, the conveying line bodies 1 are connected end to end and arranged in a straight line. In this embodiment, the conveying line bodies 1 are inclined. Specifically, the shorter side m of the conveying line body 1 forms a predetermined angle α with the horizontal plane, and the inclination angles of all the conveying line bodies 1 are the same, so as to facilitate the smooth connection of the infusion soft bags between adjacent conveying line bodies 1. During conveying, the infusion soft bags are placed along the width direction of the conveying line body 1. By inclining the conveying line body 1, the liquid in the infusion soft bag is concentrated on one side, which is beneficial to fully detecting foreign matters in the liquid. At the same time, compared with the way of placing the infusion soft bag flat, the inclined placement can also reduce the shaking of the liquid in the bag, further ensuring the detection accuracy. On the other hand, this inclined setting method has better stability than the method of inclining the longer side n. Any abnormal situation such as the dropping of an infusion soft bag will not affect other infusion soft bags, and this inclined setting method can also accommodate a larger number of infusion soft bags, effectively improving the detection efficiency.

[0034] In a preferred embodiment, the inclination angle α of the conveying line body 1 is set between 10° and 45°. This angle can not only ensure the stable placement of the infusion soft bag, but also make the liquid in the bag concentrate and fill in one direction.

[0035] Exemplarily, the conveying line body 1 can adopt existing conveying structures such as belt conveyors or conveying chain plates, which are selected according to actual needs. By fixedly connecting multiple groups of angle support parts in the length direction of the frame of the conveying line body 1, it can be set to an inclined structure. The angle support part preferably adopts a tripod structure with stable structure. By replacing tripods with different specifications and angles, the inclination angle of the conveying line body 1 can be adjusted.

[0036] More specifically, in this embodiment, the adjacent two conveying line bodies 1 are set with background colors of different depths: preferably white or black. The conveying line body 1 with a white background is used to detect dark foreign matters under bright field, and the conveying line body 1 with a black background is used to detect reflective foreign matters under dark field. The light source 6 illuminates the infusion soft bag at the detection station 2, and the imaging device 5 captures the picture of the infusion soft bag to detect the appearance of the infusion soft bag and foreign matters in the bag. By using the cooperation of the white background and the black background for the conveying line body 1, various colors of foreign matters in the bag can be recognized more accurately, and the cooperation with the imaging device 5 and the light source 6 can perform more accurate detection on the appearance and foreign matters of the infusion soft bag.

[0037] In a preferred embodiment, as Figure 1 shown, each conveying line body 1 can be provided with two or more groups of detection stations 2 according to its conveying length to further improve the detection accuracy.

[0038] In another preferred embodiment, to prevent the soft bag from slipping off the conveyor line 1 in an inclined state, the belt or chain plate of the conveyor line 1 can be made of anti-slip material or structure. For example, anti-slip particles can be coated. More preferably, a baffle is further provided on the bottom side of the conveying surface of the conveyor line 1 to block the infusion soft bag.

[0039] Embodiment 2

[0040] The following refers to Figures 3 - 5 to describe the second embodiment of the present invention. The infusion soft bag quality inspection device provided by the second embodiment has substantially the same structure as the infusion soft bag quality inspection device provided by the first embodiment. Therefore, for the sake of brevity, only the differences will be described in detail here.

[0041] In the second embodiment, the lamp inspection part includes a first lamp inspection part 3 and a second lamp inspection part 4. The first lamp inspection part 3 corresponds to the inspection station 2 of the conveyor line 1, and the second lamp inspection part 4 corresponds to the connection gap position between two adjacent conveyor lines 1, and is used to inspect the infusion soft bag at the middle gap where two conveyor lines 1 are connected. The gap inspection can avoid the influence of the dirt on the surface of the conveyor line 1 on the imaging of the infusion soft bag.

[0042] In the second embodiment, there can be various combination forms for the orientation of the shooting member 5 and the light source 6 in the second lamp inspection part 4:

[0043] Exemplarily:

[0044] In one combination form, as Figure 3 shown, in the second lamp inspection part 4, both its shooting member 5 and light source 6 are placed above the conveyor line 1, that is, in the front. In this embodiment, the shooting member 5 of the second lamp inspection part 4 uses a line-scan camera to trigger and take pictures at different times, and can obtain bright-field, dark-field and soft bag images at the gap position at the same station, making the detection range larger and the detection result more accurate.

[0045] In one combination form, as Figure 4 、 Figure 5 shown, the light source 6 of the second lamp inspection part 4 is placed in the front or back of the conveyor line 1, and the shooting member 5 is placed on the back of the conveyor line 1 to obtain the soft bag image at the gap position from the back. Since there may be instructions on one side of the infusion soft bag, obtaining the back image according to the actual situation can ensure the accurate identification of foreign objects in the liquid in the bag.

[0046] In one combination form, as Figure 6 shown, two shooting members 5 are provided in the second lamp inspection part 4, one of which is placed in the front of the conveyor line 1 and the other is placed on the back of the conveyor line 1, and the infusion soft bag is photographed from the front and back at the same time to further improve the detection accuracy.

[0047] The above three combination forms are for illustrative purposes only and are not limited to the above three combination forms. Those skilled in the art can understand that if the number of conveying line bodies 1 is large enough, the second lamp inspection parts 4 are provided at the connection gaps of each conveying line body, and the orientations of the shooting parts 5 and the light sources 6 of the second lamp inspection parts 4 can be set in different combination forms at each connection gap position, so as to achieve the multi-dimensional detection effect while saving costs.

[0048] Embodiment 3

[0049] The following refers to Figures 7 - 9 to describe the third embodiment of the present invention. The infusion soft bag quality inspection device provided by the third embodiment has substantially the same structure as the infusion soft bag quality inspection device provided by the second embodiment. Therefore, for the sake of brevity, only the differences will be described in detail here.

[0050] As Figure 7 shown, two adjacent conveying line bodies 1 form a conveying line body group 9. In this embodiment, the infusion soft bag quality inspection device further includes an attitude adjustment part 7 provided between two adjacent conveying line body groups 9. The attitude adjustment part 7 is used to adjust the attitude of the infusion soft bag and also to connect the two conveying line body groups 9 to enable the infusion soft bag to smoothly transition. By means of the attitude adjustment part 7, the infusion soft bag and the liquid therein during the conveying process are shaken, so as to prevent foreign matters from adhering to the side of the soft bag, which is beneficial to the identification of foreign matters.

[0051] In this embodiment, the attitude adjustment part 7 adopts the structure of an existing circular belt conveyor. The circular belt conveyor consists of a number of conveying rollers arranged at different angles and capable of rotating. After the infusion soft bag is conveyed to the attitude adjustment part 7, it is driven forward by each conveying roller. During the forward process, the angle of the infusion soft bag gradually changes with the change of the angle of the conveying roller. The attitude adjustment part 7 can adjust the orientation of the infusion soft bag so that its angles are respectively consistent with those of two adjacent conveying line body groups 9.

[0052] Refer to Figures 7 - 9 and Figure 3 , in an embodiment, the inclination angles of two adjacent conveying line body groups 9 are different. Preferably, among two adjacent conveying line body groups 9, the inclination angle of one conveying line body group 9 is an acute angle, and the inclination angle of the other conveying line body group 9 is an obtuse angle. Exemplarily, if the inclination angle of the previous conveying line body group 9 relative to the horizontal plane is 30°, then the inclination angle of the adjacent subsequent conveying line body group 9 relative to the horizontal plane is 150°. This setting can make the liquid in the infusion soft bag tilt and fill in two directions, with a large shaking amplitude, so as to prevent foreign matters from adhering to difficult-to-identify positions such as the side of the soft bag.

[0053] Exemplarily, the front conveying roller of the attitude adjustment unit 7 has the same inclination angle as that of the previous conveying line group 9, so that the infusion soft bag on the previous conveying line group 9 can smoothly transition to the front conveying roller of the attitude adjustment unit 7. At this time, the infusion soft bag moves forward along with the conveying roller of the attitude adjustment unit 7 until it reaches the rear conveying roller with the same inclination angle as that of the next conveying line group 9. Through the rear conveying roller, the infusion soft bag on the attitude adjustment unit 7 can smoothly transition to the next conveying line 1.

[0054] Those skilled in the art can understand that in other embodiments, the attitude adjustment unit 7 can also adopt a soft bag clamping manipulator to realize the transfer of the infusion soft bag between the two conveying line groups 9.

[0055] Embodiment 4

[0056] Reference Figure 10 , in this embodiment, the infusion soft bag quality inspection device further includes a rejection conveyor 8 connected to the end conveying line 1. The rejection conveyor 8 is swingable. The software analyzes the captured images to determine whether they are qualified products or unqualified products. The qualified products and unqualified products respectively correspond to the qualified product conveying line and the unqualified product conveying line.

[0057] The swinging structure of the rejection conveyor 8 can be realized by the following structure: one end of the rejection conveyor 8 is rotatably connected to the corresponding frame, and the rejection conveyor 8 is driven by a driving structure to swing by a predetermined amplitude so that it corresponds to the qualified product conveying line and the unqualified product conveying line respectively, so as to realize the rejection of unqualified products.

[0058] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and do not limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
