Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a double-bottle testing machine. Background Technology

[0002] The production process of horizontal ampoules involves the entire process from glass tubes to ampoule forming, annealing, and packaging, requiring a long production line. When the glass tubes are produced as semi-finished bottles (double ampoules) on the horizontal ampouling machine, the critical dimensions of the product are typically only checked by cold-end inspection equipment after annealing. If a problem is found, the entire semi-finished bottle from the forming stage to the cold-end inspection stage must be discarded. Even after adjustments are made to the double-ampoule forming process, the formed double-ampoules still need to undergo cold-end inspection to determine if the process at the forming station is properly adjusted. This process wastes a significant number of double ampoules. Currently, the market urgently needs timely inspection of the critical dimensions of semi-finished products (double ampoules) without affecting production efficiency (inspection speed less than 0.7 seconds) to reduce waste.

Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0032] This embodiment describes a double-bottle inspection machine, which can be installed at the station of a horizontal ampoule production line that produces semi-finished bottles (double-bottles) to inspect the key dimensions of each semi-finished bottle.

[0033] like Figure 1 As shown, the inspection machine includes a frame 1, a bottle-dispensing mechanism 2, a dial mechanism 3, a light source 4, a camera 5, a first detection sensor 6, a second detection sensor 7, a first alarm 8, a second alarm 9, and a positioning sensor 11 (see...). Figure 3 The frame 1 is installed at the end of the production line of the molding station to be inspected. The bottle-dispensing mechanism 2, the wheel-dispensing mechanism 3, the light source 4, the camera 5, the second detection sensor 7, the second alarm 9, and the positioning sensor 11 are respectively installed on the frame 1. The first detection sensor 6 and the first alarm 8 are respectively installed on the front frame in front of the inspection machine.

[0034] like Figure 2 and Figure 3 As shown, the end of the production line at the molding station to be inspected is connected to the dial wheel mechanism 3 via an input plate. The input plate is inclined downwards from the end of the production line towards the dial wheel mechanism 3. The input plate has a groove that matches the drive wheel 3.2 of the dial wheel mechanism 3 to prevent the input plate from obstructing the rotation of the drive wheel 3.2. Bottles 10 that have moved to the end of the production line at the molding station to be inspected roll down to the bottom of the input plate by gravity.

[0035] The bottle-dispensing mechanism 2 is installed inside the frame 1 above the end of the production line at the forming station to be inspected. It is used to guide the bottles 10 conveyed to the end of the production line toward the guide wheel mechanism 3, increasing the speed at which the bottles 10 fall onto the input plate. The bottle-dispensing mechanism 2 includes a bottle-dispensing motor 2.1, a rotating shaft, and guide plates 2.2. The rotating shaft is installed inside the frame 1 in the conveying direction of the production line, with its two ends mounted on the left and right side plates of the frame 1, respectively. The bottle-dispensing motor 2.1 is installed on the outside of one side plate of the frame 1, and its output shaft is connected to the rotating shaft. Multiple guide plates 2.2 are evenly distributed around the rotating shaft. The bottle-dispensing motor 2.1 drives the rotating shaft to rotate, and the guide plates 2.2 guide the bottles 10 that have moved to the bottom of the bottle-dispensing mechanism 2 on the production line to the bottom of the input plate. Then, the guide wheel mechanism 3 drives the bottles 10 into the inspection station.

[0036] The dial mechanism 3 is located below the bottle-dispensing mechanism 2 and includes a dial motor 3.1, a drive wheel 3.2, and a driven wheel 3.3. Both the drive wheel 3.2 and the driven wheel 3.3 are grooved wheels. The dial motor 3.1 is mounted on the outside of one side plate of the frame 1. The drive wheel 3.2 and the driven wheel 3.3 are mounted inside the frame 1 along the conveying direction of the production line via axles. The axles of the drive wheel 3.2 and the driven wheel 3.3 are mounted on the left and right side plates of the frame 1, respectively, and are connected by a transmission structure (such as a synchronous belt or chain). The drive wheel 3.2 and the driven wheel 3.3 are arranged alternately, forming an intersection area, which is the inspection station for the bottles 10. The output shaft of the dial motor 3.1 is connected to the axle of the drive wheel 3.2, and the dial motor 3.1 drives the driven wheel 3.3 to rotate through the drive wheel 3.2. The input plate is connected to the drive wheel 3.2, and the driven wheel 3.3 is connected to the output production line via the output plate. The output plate is inclined downwards from the driven wheel 3.3 toward the output production line. Preferably, the output plate has a convex plate, and the width of the convex plate is smaller than the middle gap of the driven wheel 3.3, so that the convex plate can be inserted into the middle of the driven wheel 3.3 to support the bottle 10 that has rotated to this position, so that the bottle 10 can detach from the driven wheel 3.3 and roll onto the output production line.

[0037] In this embodiment, the driving wheel 3.2 and the driven wheel 3.3 each have a V-groove, the opening size of which is no larger than the outer diameter of the bottle 10. The driving wheel 3.2 uses the V-groove to carry the bottle 10 from the bottom of the input plate, and the bottle 10 rotates together with the driving wheel 3.2 until it reaches the detection station. When the driving wheel 3.2 and the driven wheel 3.3 rotate, the bottle 10 rotates through the arc portion of the driving wheel 3.2 and the driven wheel 3.3 until the driven wheel 3.3 uses the V-groove to carry the bottle 10 away from the detection station. After the bottle 10 contacts the output plate, it rolls off the output plate and onto the output production line by gravity.

[0038] Two cameras 5 are symmetrically mounted at an angle inside the frame 1 above the bottle-dispensing mechanism 2. The lenses of the cameras 5 face the inspection station to the side and are connected to the central control unit. When the bottle 10 rotates at the inspection station, the two cameras 5 take pictures of both ends of the bottle 10 and transmit the pictures to the central control unit for processing and analysis to inspect the appearance and size of both ends of the bottle 10.

[0039] Two light sources 4 are installed at an angle inside the frame 1 below the driven wheel 3.3, and are respectively aligned with the two cameras 5. The light source surface of the light source 4 faces the detection station to enhance the light source at the detection station, thereby improving the image clarity of the camera 5 and avoiding shadows at the detection station that would affect the detection accuracy.

[0040] In this embodiment, the first detection sensor 6, the second detection sensor 7, and the positioning sensor 11 are, but are not limited to, photoelectric sensors and fiber optic sensors. The first detection sensor 6, the second detection sensor 7, the positioning sensor 11, the first alarm 8, and the second alarm 9 are respectively connected to the central control unit.

[0041] A first detection sensor 6 and a first alarm 8 are respectively installed on the front frame of the inspection machine. The first detection sensor 6 is used to detect whether a bottle blockage has occurred on the production line and transmits the blockage signal to the central control unit. When the central control unit determines that a bottle blockage has occurred based on the detection signal transmitted by the first detection sensor 6, the central control unit controls the first alarm 8 to sound an alarm.

[0042] A second detection sensor 7 is installed on the frame 1 at the end of the production line of the molding station to be inspected, located below the bottle-dispensing mechanism 2. It is used to detect whether the bottle 10 has reached the end of the production line of the molding station to be inspected and whether bottle blockage has occurred. A second alarm 9 is installed on the frame 1. When the central control unit receives the signal from the second detection sensor 7 that the bottle 10 has arrived, it controls the bottle-dispensing mechanism 2 to start, which dispenses the bottle 10 through the dispensing plate 2.2. When the central control unit receives the bottle blockage signal from the second detection sensor 7, it triggers a bottle blockage alarm through the second alarm 9.

[0043] When the inspection machine is installed in a horizontal ampoule production line, the positioning sensor 11 is installed on the frame 1 and connected to the central control unit at the forming station to be inspected, and is used to locate the forming station where the bottle 10 is located.

[0044] The double-bottle inspection machine of this embodiment is installed in a horizontal ampoule production line. Its operation is as follows: When the second detection sensor 7 senses the bottle 10, the double-bottle inspection machine starts. The dial motor 2.1 drives the dial plate 2.2 via a rotating shaft to move the bottle 10 towards the dial wheel mechanism 3. Driven by the dial wheel motor 3.1, the drive wheel 3.2 uses a V-groove to bring the bottle 10 to the inspection station. The drive wheel 3.2 and the driven wheel 3.3 rotate the bottle 10 at the inspection station via an arc section. Simultaneously, during the rotation of the bottle 10, the camera 5 continuously and evenly takes multiple pictures of the end of the bottle 10 and transmits the images to the central control unit. After the V-groove of the driven wheel 3.3 rotates to the inspection station, the driven wheel 3.3 uses the V-groove to move the bottle 10 away from the inspection station and sends it to the output production line via the output plate. During the above inspection process, the central control unit determines the forming station where the bottle 10 is located based on the detection signal from the positioning sensor 11 and records the corresponding inspection data.

[0045] In this embodiment, the bottle-feeding mechanism and the wheel-feeding mechanism are combined with the detection sensor and the central control unit to automatically detect the slot, thereby improving the detection speed to as fast as 0.5s. In this embodiment, the semi-finished bottles pass through the inspection machine in a horizontal manner. That is, the inspection machine only needs to ensure that the inner diameter of the frame is not less than the length of the semi-finished bottle along the production line direction. Therefore, the width of the inspection machine along the production line direction can be as small as less than 300mm, which is small in size and easy to arrange on the production line.

[0046] Although the principles of this utility model have been described in detail above with reference to preferred embodiments, those skilled in the art should understand that the above embodiments are merely illustrative explanations of the implementation of this utility model and are not intended to limit the scope of this utility model. The details in the embodiments do not constitute a limitation on the scope of this utility model. Any obvious changes, such as equivalent transformations or simple substitutions, based on the technical solution of this utility model without departing from its spirit and scope fall within the protection scope of this utility model.
