Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical bottle production technology, specifically a large-capacity pharmaceutical bottle testing line. Background Technology

[0002] Pharmaceutical glass bottles are widely used due to their advantages such as smooth transparency, ease of sterilization, corrosion resistance, high temperature resistance, and good sealing performance. Currently, pharmaceutical glass bottles remain the preferred packaging containers for common infusion solutions, antibiotics, powders, lyophilized products, vaccines, blood, and biological agents.

[0003] After production, pharmaceutical glass bottles need to be inspected for their dimensions, such as their total length. However, there are many types of pharmaceutical glass bottles, ranging from small bottles with a volume of 1 ml to large bottles with a volume of over ten liters. The volume of pharmaceutical bottles varies greatly, and the inspection methods are also different. For small-volume pharmaceutical bottles, they can be directly gripped by grippers and placed at a vision inspection device to inspect the total length of the bottle. However, for large-volume pharmaceutical bottles, it is more difficult to use the above method because they are harder to grip. At the same time, the accuracy of vision inspection for the total length of large-volume pharmaceutical bottles is not high. Therefore, a new method is needed to inspect the total length of large-volume pharmaceutical bottles. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a large-capacity medicine bottle inspection line that can inspect the entire length of large-capacity medicine bottles. The entire length inspection process does not employ visual inspection, resulting in high accuracy. Furthermore, the inspection can be performed on the conveyor track, eliminating the need to remove the medicine bottles from the conveyor track.

[0005] The technical solution is as follows: a large-capacity medicine bottle testing line, which includes a conveying track and a full-length testing station, characterized in that: multiple bearing blocks are provided on the conveying track, a bearing groove is provided in the middle of the bearing block, the bearing groove is used to place large-capacity medicine bottles horizontally, and the two ends of the bearing groove along the length of the medicine bottle are open respectively.

[0006] The full-length inspection station includes an inspection mechanism and a limiting plate. The inspection mechanism and the limiting plate are located on both sides of the carrier block on the conveying track. The inspection mechanism includes a displacement sensor, a double-rod cylinder, and a mounting bracket. The displacement sensor and the double-rod cylinder are respectively mounted on the mounting bracket. The double-rod cylinder includes a piston rod one and a piston rod two capable of bidirectional constant speed movement. The piston rod one is used to contact the displacement sensor, and the piston rod two is used to contact the large-volume medicine bottle to be inspected on the carrier block. The piston rod two can push one end of the large-volume medicine bottle in its length direction and make its other end abut against the limiting plate.

[0007] Furthermore, the mounting bracket includes a base, a horizontal position adjustment mechanism, and a mounting seat. The horizontal position adjustment mechanism is mounted on the base. The horizontal position adjustment mechanism includes a guide rail, a slider, and a locking bolt. The slider is mounted on the guide rail and can move along the straight line along the length of the large-capacity medicine bottle. The locking bolt is used to fix the slider on the guide rail. The mounting seat is mounted on the slider and is used to fix the displacement sensor and the double-rod cylinder.

[0008] Furthermore, the testing line also includes an inner diameter testing station, which includes a visual inspection device located on one side of the support block and a light source located on the other side of the support block, with the mouth of the large-capacity medicine bottle facing the visual inspection device.

[0009] Furthermore, the visual inspection device includes a second horizontal position adjustment mechanism and a camera. The second horizontal position adjustment mechanism includes a second base and an adjustment seat. The camera is mounted on the adjustment seat, and the second base is connected to the adjustment seat via a lead screw pair.

[0010] Beneficial effects: By setting a support block on the conveyor track, large-capacity medicine bottles are placed horizontally on the support block, which facilitates the placement and transportation of large-volume bottles. The specific structure of the full-length detection station, combined with this placement method, allows the large-capacity medicine bottle to be pushed against the limiting plate by piston rod two during detection. The displacement sensor is triggered by piston rod one, which moves at the same speed as piston rod two, to obtain the pushing distance. By comparing this distance with the reference distance obtained by placing standard parts, it is possible to detect whether the full length of the bottle meets the requirements.

[0014] Figure 4 This is a schematic diagram of the structure at the inner diameter testing station. Detailed Implementation

[0015] like Figure 1 The large-capacity medicine bottle testing line shown includes a conveyor track 1 and a full-length testing station 2. The conveyor track 1 is equipped with multiple... Figure 2The carrier block 101 shown can be installed on a conveyor chain driven by a sprocket or on a synchronous belt driven by a synchronous pulley. The carrier block 101 has a carrier groove in the middle, which is U-shaped or V-shaped. The carrier groove is used to place large-capacity medicine bottles 100 laterally. The two ends of the carrier groove are open along the length of the medicine bottle.

[0016] Combination Figure 3 As shown, the full-length inspection station 2 includes an inspection mechanism and a limiting plate 201, which are located on both sides of the carrier block 101 on the conveying track 1. Figure 3 The detection mechanism has two sets of mechanisms arranged in parallel, including a displacement sensor 202, a double-rod cylinder 203, and a mounting bracket 204. The displacement sensor 202 and the double-rod cylinder 203 are respectively mounted on the mounting bracket 204. The displacement sensor 202 can be a Keyence GT-H10 contact sensor, and the double-rod cylinder 203 can be an SMC CJ2W series double-rod cylinder. The double-rod cylinder 203 includes a piston rod one and a piston rod two capable of bidirectional constant speed movement. The piston rod one is used to contact the displacement sensor 202, and the piston rod two is used to contact the large-capacity medicine bottle 100 to be detected on the support block 101. The piston rod two can push one end of the large-capacity medicine bottle 100 in its length direction and make its other end abut against the limiting plate 201.

[0017] Specifically, the mounting bracket 204 includes a base 205, a horizontal position adjustment mechanism 1, and a mounting seat 206. The horizontal position adjustment mechanism 1 is mounted on the base 205. The horizontal position adjustment mechanism 1 includes a guide rail 207, a slider 208, and a locking bolt 209. The slider 208 is mounted on the guide rail 207 and can move along the straight line along the length of the large-capacity medicine bottle 100. The locking bolt 209 is used to fix the slider 208 on the guide rail 207. The mounting seat 206 is mounted on the slider 208. The mounting seat 206 is used to fix the displacement sensor 202 and the double-rod cylinder 203.

[0018] During the full-length inspection, the double-rod cylinder 203 is activated, and the piston rods at both ends extend at the same speed. One end pushes the bottle body, and the other end squeezes the detection head of the displacement sensor 202 until the end of the large-capacity medicine bottle 100 is pressed against the limiting plate 201 and the extension stops. At this time, the extension distance can be obtained through the displacement sensor 202. By comparing this distance with the reference distance obtained by placing the standard part, it can be determined whether the full length of the bottle meets the requirements.

[0019] In addition, combined Figure 1 , Figure 4As shown, the inspection line also includes an inner diameter inspection station 3. The inner diameter inspection station includes a vision inspection device located on one side of the support block 101 and a light source 301 located on the other side of the support block. The bottle mouth of the large-capacity medicine bottle 100 faces the vision inspection device. The vision inspection device includes a second horizontal position adjustment mechanism and a camera 303. The second horizontal position adjustment mechanism includes a second base 302 and an adjustment seat 304. The camera 303 is mounted on the adjustment seat 304. The second base 302 is connected to the adjustment seat 304 through a lead screw pair 305, so that the relative position of the camera 303 and the large-capacity medicine bottle 100 can be adjusted through the lead screw pair 305.

[0020] Meanwhile, since the large-capacity medicine bottle 100 placed horizontally can have its inner diameter visually detected by photographing its mouth, and this size is smaller than the total length of the bottle, making it more suitable for visual detection, by utilizing the horizontal placement of the large-capacity medicine bottle 100, the light source 301 can illuminate the large-capacity medicine bottle 100 through the bottom of the bottle and the camera 303 can obtain a visual image of the mouth position to determine whether the inner diameter of the mouth meets the requirements.

[0021] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
