Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, a medicine bag opening shape detecting device, a medicine bag 2 is fixed in a medicine bag movable frame 1 to receive medicine falling; one end of the medicine bag 2 is provided with a medicine bag vertical edge 8, and the end part of the medicine bag vertical edge 8 is provided with a vertical edge detection sensor 6 so as to detect the qualified medicine bag vertical edge 8; a height detection sensor 3 is installed at the other end of the medicine bag 2 to detect the height of the medicine bag 2 extending out of the medicine bag movable frame 1; according to the medicine falling region, a qualified detection region (medicine falling equipment is not shown in the figure) at the opening of the medicine bag 2 can be determined, and radian detection sensors are respectively installed on two sides of the vertical edge 8 of the medicine bag so as to detect the deformation of the medicine bag 2 in the qualified detection region.
The vertical limit 8 of medicine bag is located the guide membrane groove 11 of medicine bag adjustable shelf 1 under the normal condition, but can be accidentally sent the condition that the vertical limit 8 of medicine bag did not stretch into guide membrane groove 11 completely, through the tip installation vertical limit at medicine bag vertical limit 8 and detect sensor 6, whether the detection has the signal of sheltering from and judges whether medicine bag vertical limit 8 stretches into guide membrane groove 11 completely. The other end of the medicine bag 2, namely one end without the vertical edge 8 of the medicine bag, is provided with a height detection sensor 3 for detecting the height of the medicine bag 2 to judge whether the height of the medicine bag 2 is within a set height threshold value, and if the height is within the height threshold value, the medicine bag is qualified.
It should be noted that, the one end of installing height detection sensor 3 is not installed radian detection sensor and is detected the deflection of medicine bag 2, because observe through a large amount of experiments, the medicine bag 2 of this tip is out of shape and is taken place seldom, and the deformation of medicine bag 2 almost all takes place in the both sides of medicine bag vertical edge 8, for the consideration of cost and emergence probability, it can to propose installing radian detection sensor in the both sides of medicine bag vertical edge 8. Of course, if the deformation of the medicine bag is to be detected accurately, the radian detecting sensors may be installed on both sides of the installation end of the height detecting sensor 3 to detect the medicine bag 2.
Radian detection sensors are respectively arranged on two sides of the vertical edge 8 of the medicine bag and used for detecting the radian deformation of the medicine bag 2 and judging whether the radian deformation is saturated or not, and qualified detection areas are arranged at the openings of the medicine bag 2 and are determined by medicine falling areas as shown in figure 3. Because each production line, the difference of the process flow and the difference of the size of the medicine falling regulating head can cause the size of the medicine falling area to be different, the medicine falling area is determined in advance according to the process equipment, and then the qualified detection area at the opening of the medicine bag 2 is determined. After the qualified detection area at the opening of the medicine bag 2 is determined, the radian detection sensor can detect the deformation of the medicine bag 2 and judge whether the deformation is in the qualified detection area. As shown in fig. 3, if the radian of the light 7 emitted by the radian detection sensor exceeds the edge contour line of the medicine falling region 12, the unqualified medicine bag is determined.
In this embodiment, a vertical edge qualified detection area is preset at the position of the vertical edge 8 of the medicine bag, and the vertical edge detection sensor 6 detects the vertical edge 8 of the medicine bag in the vertical edge qualified detection area, which is the qualified vertical edge 8 of the medicine bag.
In general, the widths of the vertical edges 8 of the medicine bag are different, the extending ranges in the film guide groove 11 are different, and the vertical edges are folded and do not completely extend. Therefore, at the position of the vertical edge 8 of the medicine bag, i.e. the position of the film guiding groove or other structures, as shown in fig. 3, the qualified detection area of the vertical edge is preset according to the process requirements, when the vertical edge detection sensor 6 detects the vertical edge 8 of the medicine bag in the qualified detection area of the vertical edge, the vertical edge 8 of the medicine bag is qualified, and the width of the vertical edge 8 of the medicine bag extending into the vertical edge 8 meets the process requirements. The vertical edge detection sensor 6 does not detect the vertical edge 8 of the medicine bag in the vertical edge qualified detection area, namely the vertical edge 8 of the unqualified medicine bag, and the extending width of the vertical edge 8 of the medicine bag does not meet the technological requirements.
The utility model discloses in, in radian detection sensor detects and obtains medicine bag opening deflection and be in the region of passing through, it is qualified that the width is stretched into to medicine bag vertical side 8, and the high data that high detection sensor 3 detected simultaneously is in high threshold value, and then 2 opening shapes of medicine bag are promptly qualified, otherwise are unqualified.
In an alternative embodiment, the height detection sensor 3 is fixedly mounted on the first bracket 9, and the vertical edge detection sensor 6 and the two radian detection sensors are fixedly mounted on the second bracket 10. The medicine bag moving frame 1 can drive the medicine bag 2 to move between the first support 9 and the second support 10. On height detection sensor 3, vertical edge detection sensor 6 and two radian detection sensors fixed bolster respectively, medicine bag 2 is in medicine bag adjustable shelf 1, along with medicine bag adjustable shelf 1 removes, and a medicine bag 2 detects and accomplishes, and medicine bag adjustable shelf 1 removes, and another medicine bag 2 reachs the detection position and continues to detect, and it is convenient to detect. The 4 sensors are respectively arranged on the bracket, so that the detection of the opening shape of the medicine bag 2 can be completed through detecting key points of the medicine bag 2, and the occupied space is small. In this embodiment, 4 sensors are taken as an example to briefly explain the effect of detection, and if it is necessary to further ensure the accuracy of the detection data of each end, the number of sensors may be increased, and the present embodiment is not limited to 4 positions and the corresponding 4 sensors.
In this embodiment, the vertical edge detection sensor 6 is fixed above any one of the two arc detection sensors, and any one of the two arc detection sensors can detect the height of the medicine bag 2.
For convenience of introduction, the radian detecting sensors are divided into a lower left radian detecting sensor 4 and a lower right radian detecting sensor 5 according to the installation position. The vertical edge detection sensor 6 is installed and fixed above any one of the lower left radian detection sensor 4 and the lower right radian detection sensor 5, so that the occupied space of the whole sensor can be further reduced, and meanwhile, the emission point of the emission light 7 of the vertical edge detection sensor 6 is easier to adjust due to the fact that the position is heightened.
Any one of the lower left arc detection sensor 4 and the lower right arc detection sensor 5 can detect the height of the medicine bag 2, so as to ensure that the height of the end of the vertical edge 8 of the medicine bag is equal to or within a predetermined difference range with the height data of the height detection sensor 3, that is, the opening height of the medicine bag 2 at the end of the vertical edge 8 of the medicine bag is parallel to and level with the height of the other end, and the opening shape of the medicine bag 2 can be further ensured. One of the left lower radian detection sensor 4 and the right lower radian detection sensor 5 is selected to have the function of detecting the height, so that the equipment cost with few functions can be further reduced, and the setting work of equipment parameters can be reduced if the same sensors are selected.
In an optional embodiment, the vertical edge detection sensor 6, the height detection sensor 3 and the radian detection sensors on two sides all select reflective photoelectric sensors, and the same sensor is selected at the position 4, so that the installation process can be universal, and the classification work is reduced.
The reflection photoelectric sensor emits light 7 to the emitting path of the medicine bag and the vertical edge of the medicine bag, the reflection path receives a reflection signal, the interior of the sensor processes the received signal, and then whether the vertical edge of the medicine bag extends into a qualified area or not and whether the two sides of the vertical edge of the medicine bag are saturated or not can be judged, and if the vertical edge of the medicine bag is not saturated, the inward sinking distance of the medicine bag can be measured. At present, the sensor is developed rapidly, data processing can be carried out in the sensor, and whether a detection result is qualified or not can be directly fed back in the detection process through presetting parameters of the sensor, so that the detection work of the opening shape of the medicine bag is realized.
