Description

Technical Field

[0001] The utility model relates to the technical field of pill packaging equipment, and particularly relates to a detection mechanism for spherical pills. Background Art

[0002] The plastic spherical shell of traditional Chinese medicine pills can protect the medicine from external pollution, such as the influence of dust, air, etc. on the medicine. Moreover, since the production of traditional Chinese medicine pills is relatively troublesome, the produced traditional Chinese medicine pills often need to be transported to pharmacies in other cities for sale. And during the whole sales process, the traditional Chinese medicine pills need to be protected from moisture, mildew, etc. Only by using a plastic spherical shell can their integrity be ensured.

[0003] During the packaging process of pills, it is necessary to detect whether there is a pill placed inside the pill shell and whether the shell is properly closed to ensure the quality of the pills. However, in the prior art, it is generally detected manually. Employees are prone to miss detection, misdetection, etc. after working for a long time, resulting in a significant increase in defective products. Content of the Utility Model

[0004] To solve the technical problems in the background art, the utility model provides a detection mechanism for spherical pills.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A detection mechanism for spherical pills includes a test seat for placing the pill shell, a closing measurement structure for measuring the height of the pill shell, and a weight detection structure for measuring the weight of the pill shell;

[0007] The closing measurement structure includes a probe assembly and a lifting module for driving the probe assembly to lift and lower. The measurement probe assembly includes a measurement bracket, a test needle movably arranged on the measurement bracket, and a detection sensor for calculating the lifting height of the test needle;

[0008] The weight detection structure includes a weighing rod, a weighing unit arranged at the bottom of the weighing rod, and a moving module for driving the weighing unit to move up and down. And a weighing hole for the weighing rod to be inserted is formed on the test seat.

[0009] Preferably, the detection sensors are arranged on both sides of the measurement bracket, and a pair of shooting grooves are formed on the test needle. The test needles are paired through the pair of shooting grooves. Through the above improvement, when in the initial state, the test probes on both sides can be paired through the pair of shooting grooves. When testing, the test needle presses the pill shell, the test needle rises, and the pair of shooting grooves also rise accordingly. After rising to a specified height, the test needles cannot be paired through the test needle, thereby sending out a non-conforming signal. If the test needles can still be paired after rising a certain height, it indicates that the pill shell is properly closed, realizing the detection of the closing of the pill shell.

[0010] Preferably, a first mounting plate and a second mounting plate are provided on the measuring bracket, the test needle is inserted on the first mounting plate and the second mounting plate, a limiting convex portion is formed on the outer periphery of the test needle, the limiting convex portion abuts against the upper surface of the second mounting plate, and an elastic element is sleeved on the test needle, one end of the elastic element abuts against the limiting convex portion, and the other end abuts against the lower surface of the first mounting plate. Through the above improvement, the elastic element acts on the limiting convex portion, so that the test needle always has a tendency to move downward, so that after the test needle is separated from the pill shell, the test needle will automatically reset to improve the test efficiency.

[0011] Preferably, an adjusting rod is movably arranged in the test needle, a part of the adjusting rod is placed in the opposed slot, and the adjusting rod moves up and down along the opposed slot to adjust the size of the opposed slot. Through the above improvement, the stroke of the opposed slot can be adjusted according to the size of different pill shells. When it is necessary to test a large-sized pill shell, the stroke of the adjusting rod extending into the opposed slot can be reduced. On the contrary, when it is necessary to test a small-sized pill shell, the stroke of the adjusting rod extending into the opposed slot can be increased, so as to cooperate with pill shells of different sizes.

[0012] Preferably, a first arc surface that fits the outer surface of the pill shell is formed at the bottom of the test needle. Through the above improvement, since the pill shell is spherical, the first arc surface can better fit the pill shell to improve the stability during the test.

[0013] Preferably, the covering and measuring structure further includes an adjusting bracket, an adjusting block is movably arranged on the adjusting bracket, and the adjusting block is connected to the measuring bracket. Through the above improvement, the height of the entire covering and measuring structure can be adjusted according to the size of the pill shell to cooperate with different pill packages.

[0014] Preferably, a second arc surface that fits the outer contour of the pill shell is formed at the top of the weighing rod. Through the above improvement, the stability during the pill weight detection is improved.

[0015] Preferably, a connecting rib is formed on the pill shell, and a limiting groove for the connecting rib to be inserted is formed on the test seat. Through the above improvement, the limiting groove limits the connecting rib, and the stability of the pill shell during the measurement is improved.

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

[0029] It should be understood that although terms such as upper, middle, lower, top, one end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, rather than for defining any directional or sequential limitations.

[0030] As Figure 1-7 shown, a detection mechanism for spherical pills includes a test seat 1 for placing the pill shell, a closing measurement structure 2 for measuring the height of the pill shell, and a weight detection structure 3 for measuring the weight of the pill shell.

[0031] Specifically, the closing measurement structure 2 includes a probe assembly 101 and a lifting module 102 for driving the probe assembly 101 to lift and lower. The measurement probe assembly 101 includes a measurement bracket 111, a test needle 112 movably arranged on the measurement bracket 111, and a detection sensor 113 for calculating the lifting height of the test needle 112.

[0032] The weight detection structure 3 includes a weighing rod 201, a weighing unit 202 arranged at the bottom of the weighing rod 201, and a moving module 203 for driving the weighing unit 202 to move up and down, and a weighing hole 204 for the weighing rod 201 to be placed is formed on the test seat 1.

[0033] By measuring the height of the pill shell through the closing measurement structure 2, it is possible to detect whether the pill shell is properly closed. And by detecting the weight of the entire pill shell through the weight detection structure 3, it is possible to identify whether a pill is placed inside the pill shell and to determine whether the weight of the internal pill meets the standard. Compared with manual detection, the accuracy and efficiency are greatly improved, and the labor intensity of employees can be reduced.

[0034] As Figures 1 to 4 shown, for a further explanation of the height detection by the detection sensor 113 in this embodiment, wherein, the detection sensor 113 is arranged on both sides of the measurement bracket 111, and a through slot 114 is formed on the test needle 112, and the test needle 112 forms a through beam through the through slot 114.

[0035] When in the initial state, the test probes on both sides can perform opposite shooting through the opposite shooting groove 114. When testing, the test needle 112 squeezes the pill shell, the test needle 112 rises, and the opposite shooting groove 114 also rises accordingly. After rising to a specified height, the test needle 112 cannot perform opposite shooting through the test needle 112, indicating that the pill shell is not tightly covered, resulting in too high a height, and thus an unqualified signal is sent. If after rising a certain height, the test needle 112 can still form opposite shooting, it indicates that the pill shell is tightly covered and the height meets the requirements, then it shows that the pill shell is properly covered, realizing the automatic detection of the covering of the pill shell.

[0036] Specifically, a first mounting plate 115 and a second mounting plate 116 are provided on the measuring bracket 111. The test needle 112 is inserted on the first mounting plate 115 and the second mounting plate 116. A limiting convex portion 117 is formed on the outer periphery of the test needle 112, and the limiting convex portion 117 abuts against the upper surface of the second mounting plate 116. And an elastic element 118 is sleeved on the test needle 112. One end of the elastic element 118 abuts against the limiting convex portion 117, and the other end abuts against the lower surface of the first mounting plate 115.

[0037] When testing, the test needle 112 will move up and down along the first mounting plate 115 and the second mounting plate 116. Due to the action of the elastic element 118 on the limiting convex portion 117, the test needle 112 always has a tendency to move downward, so that after the test needle 112 disengages from the pill shell, the test needle 112 will automatically reset to improve the test efficiency.

[0038] In addition, an adjusting rod 119 is movably arranged in the test needle 112. A part of the adjusting rod 119 is placed in the opposite shooting groove 114, and the adjusting rod 119 moves up and down along the opposite shooting groove 114 to adjust the size of the opposite shooting groove 114.

[0039] The stroke of the opposite shooting groove 114 can be adjusted according to the sizes of different pill shells. When it is necessary to test a large-sized pill shell, the stroke of the adjusting rod 119 extending into the opposite shooting groove 114 can be reduced. On the contrary, when it is necessary to test a small-sized pill shell, the stroke of the adjusting rod 119 extending into the opposite shooting groove 114 can be increased, so as to cooperate with pill shells of different sizes.

[0040] Among them, the adjusting rod 119 is threadedly connected in the test needle 112, so that the adjusting rod 119 can be rotated to move up and down to adjust the stroke of the opposite shooting groove 114.

[0041] Preferably, the bottom of the test needle 112 is formed with a first arc surface 120 that fits the outer surface of the pill shell. Since the pill shell is spherical, the first arc surface 120 can better fit the pill shell to improve the stability during the test.

[0042] Preferably, an installation groove 208 communicating with the opposed groove 114 is formed on the second mounting plate 116, and the detection inductor 113 is threadedly connected to the installation groove 208, improving the convenience of installing the detection inductor 113.

[0043] Preferably, the covering and measuring structure 2 further includes an adjusting bracket 121. An adjusting block 122 is movably arranged on the adjusting bracket 121, and the adjusting block 122 is connected to the measuring bracket 111. The height of the entire covering and measuring structure 2 can be adjusted according to the size of the pill shell to cooperate with different pill packages.

[0044] As Figure 1 , Figure 5 , Figure 7 As shown in [figures], for further explanation of the weighing rod 201 in this embodiment, a second arc surface 205 conforming to the outer contour of the pill shell is formed at the top of the weighing rod 201, improving the stability during the detection of the pill weight.

[0045] A non-slip pad 209 is attached to the top of the weighing rod 201, and non-slip protrusions 210 are formed on the non-slip pad 209, further improving the stability of the pill during the measurement.

[0046] As Figure 6 As shown in [figures], in addition, connecting ribs 206 are formed on the pill shell in this embodiment, and limiting grooves 207 for placing the connecting ribs 206 are formed on the test seat 1. The limiting grooves 207 limit the connecting ribs 206, improving the stability of the pill shell during the measurement.

[0047] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
