Description

Technical Field

[0001] The present invention relates to the technical field of glass bottle production, and specifically to a concave body detection device for a glass bottle body. Background Art

[0002] In the production process of glass bottles, first, the molten glass liquid is injected into an in-line machine and blown through a specific glass production mold. After blowing, a series of subsequent treatment processes such as cooling and tempering are required to finally obtain glass bottle products that meet certain quality standards. Due to the relatively complex and special production process of glass bottles, there are various factors that may cause defects during the key blowing process. For example, during the blowing process, factors such as the temperature and pressure of the glass liquid and the accuracy of the mold may cause uneven blowing of the glass bottle. This unevenness will result in situations such as inconsistent thickness and width of the bottle body, and may even lead to abnormal bottle body shapes, and there may also be various minor defects on the surface. Once these defects enter the market, they will seriously affect the normal use of the product and thus fail to meet customer requirements.

[0003] In terms of defect detection of glass bottles, the existing detection methods mainly involve taking multi-angle photos of glass bottles through an inspection machine. Subsequently, a computer detection program is used to deeply analyze the taken photos, and by carefully comparing the differences between the glass bottle image and the detection frame, it is determined whether the glass bottle meets the established quality standards. For example, in a concave body detection system for a flat glass bottle production line disclosed in the existing application No. 202310176052.3, the measured data is compared with the set data to obtain a comparison result, and according to the comparison result, it is determined whether the flat glass bottle is qualified. If the flat glass bottle is unqualified, a bottle blocking signal is generated and output. This detection method can effectively detect most glass bottle defects to a certain extent. However, for some special-shaped glass bottles, especially flat-shaped special-shaped bottles and glass bottles with a wide front and back sides and a narrow side of the bottle body, the existing detection methods have obvious limitations. Since such glass bottles are prone to slight depressions on the bottle body during molding, and this slight depression is difficult to accurately identify for the existing image comparison-based detection methods. This results in some glass bottles with small defects not being discovered in time, thereby reducing the qualified rate of product delivery.

[0004] Therefore, a concave body detection device for a glass bottle body is now proposed. Summary of the Invention

Detailed implementation manners

[0034] In the present invention, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and the like shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0035] 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 of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 - 8 , in this embodiment, a concave body detection device for the bottle body of a glass bottle includes a conveying mechanism 1, which includes a main body of the machine base 11 and a conveyor belt 12 installed on the main body of the machine base 11;

[0037] Four sets of guide mechanisms 2 are arranged on the top of the conveyor belt 12, and two opposite sets of guide mechanisms 2 are arranged symmetrically, and are used for conveying and guiding glass bottles;

[0038] The protection mechanism 3 is arranged at the middle of the top side of the conveyor belt 12, and includes a first fixing plate 31 and a second fixing plate 32, and the second fixing plate 32 is provided with a detection port 35 and a limit port 36;

[0039] A plurality of adjusting mechanisms 4 installed on the conveying mechanism 1, for adjusting the horizontal position of the guiding mechanism 2 or the protecting mechanism 3;

[0040] A mounting base 5 connected to one side of the conveying mechanism 1 and a control box 6 on the other side, wherein an alarm light 7 is installed on the control box 6; the alarm light 7 can be directly driven by a digital output port of the control component, and when the solenoid valve is actuated, the alarm light 7 lights up, indicating that the defective bottle is intercepted, and notifying personnel to take out the defective bottle;

[0041] A limiting mechanism 8 mounted on the top of the mounting seat 5 corresponding to the limiting opening 36, used to clamp the concave defective bottle; and

[0042] The detection mechanism 9 includes a mounting block 91 mounted on the top of the mounting seat 5, a proximity switch 92 mounted on the mounting block 91, and a dial indicator 93 arranged on the top of the mounting seat 5. The contact end of the dial indicator 93 is equipped with a contact piece that contacts the body of the glass bottle, and a moving piece for adjusting the horizontal position of the dial indicator 93 is installed on one side of the second retaining plate 32; the signal line of the proximity switch 92 is connected to the digital input port of the control component, and the power line is powered by a 24V DC power supply. When the dial indicator feeler rod 932 is compressed to 0.2-0.3mm due to contact with the bottle body, the metal sheet at the end of the feeler rod enters the sensing range of the proximity switch 92, the switch is closed, and the signal is fed back to the control component;

[0043] With the above solution, the glass bottles are transported at a constant speed through the conveyor belt 12, and the four sets of symmetrical guide mechanisms 2 cooperate to flexibly guide the glass bottles to ensure that they move in a straight line to avoid deviation or collision damage. The glass bottles enter the detection channel formed by the first retaining plate 31 and the second retaining plate 32 in the protection mechanism 3. Normal bottles can pass smoothly. The product presses against the contact piece at the contact end of the dial indicator 93, and the entire rod of the contact end of the dial indicator 93 retreats (0.2-0.3mm) and touches the proximity switch 92. The proximity switch 92 lights up, and the bottle passes smoothly. The product is regarded as a qualified product.

[0044] When a product with a slightly sunken glass bottle body (0.3 - 0.5 mm) passes through the guard plate, the contact end of the dial indicator 93 contacts the concave surface, and the entire rod part of the contact end of the dial indicator retreats backward (0.4 - 0.5 mm). The distance between the entire rod part of the contact end and the proximity switch 92 is too far, and the proximity switch 92 cannot sense and the light does not turn on, without receiving a signal. At the same time, the solenoid valve is powered on and works normally. The limit mechanism 8 catches the defective bottle with a sunken body, and the alarm lamp 7 simultaneously displays an alarm. The product on the conveyor belt 12 cannot pass through normally. At this time, the operator will come to the site to press the push-button switch, take out the defective bottle and use special equipment to detect whether the bottle is a qualified bottle. If it is unqualified, it will be scrapped according to the mold number and the production personnel will be notified for handling.

[0045] Combining mechanical contact detection and an electric control system to achieve the detection of sunken glass bottle bodies, significantly improving detection efficiency and consistency, and reducing manual misjudgment.

[0046] Please refer to Figure 1 and Figure 6 As shown in FIGS. 10 and 11, the guiding mechanism 2 includes a support frame 21 and a protective pad 22 installed on the support frame 21. The protective pad 22 is installed on the side of the support frame 21 close to the glass bottle. The support frame 21 is connected to a support rod 23 on the side away from the protective pad 22. At least two groups of support rods 23 are connected to each group of support frames 21; several rolling wheels 24 that can roll on the conveyor belt 12 are connected to the bottom of the support frame 21; the glass bottle is conveyed between the two groups of support frames 21. The setting of the protective pad 22 reduces the wear of the bottle body, and the setting of the rolling wheels 24 reduces the friction between the support frame 21 and the conveyor belt 12.

[0047] Please refer to Figure 5 As shown in FIGS. 12 and 13, one side of the first fixing plate 31 is connected to a short rod 33, and the side of the second fixing plate 32 away from the first fixing plate 31 is connected to a short rod 33 and a long rod 34. The short rod 33 and the long rod 34 are both arranged parallel to the support rod 23. The distance between the first fixing plate 31 and the second fixing plate 32 is 0.1 mm greater than the total thickness of the glass bottle body; specifically, the distance between the first fixing plate 31 and the second fixing plate 32 is designed to avoid squeezing the normal bottle body and at the same time sensitively capture the sunken defect.

[0048] Please refer to Figure 1 and Figure 6, the adjustment mechanism 4 includes a base plate 41 which is fixedly connected to one side of the machine base main body 11. A guiding column 42 is installed on the top of the base plate 41, and a guiding column 42 is also installed on the top of the mounting block 91. A guiding hole is provided on the guiding column 42. A locking screw 43 is threadedly connected to the top of the guiding column 42. The top of the locking screw 43 is fixedly connected to a locking knob, and an anti-slip pad is connected to the bottom of the locking screw 43. The support rod 23, the short rod 33 and the long rod 34 are all in sliding fit with the guiding hole. Specifically, when the support frame 21 is adjusted, the support rod 23 slides in the guiding hole. After the position of the support frame 21 is adjusted, the corresponding locking knob is rotated so that the bottom end of the locking screw 43 presses against the support rod 23 to limit the sliding of the support rod 23. When the first fixing plate 31 and the second fixing plate 32 are adjusted, the corresponding short rod 33 slides in the guiding hole of the guiding column 42, and the long rod 34 of the second fixing plate 32 slides in the guiding hole of the guiding column 42 on the top of the mounting block 91. The corresponding locking knob is rotated so that the bottom end of the locking screw 43 presses against the short rod 33 and the corresponding long rod 34.

[0049] The design of the adjustment mechanism 4 also facilitates the replacement of modules such as the guiding mechanism 2 and the protection mechanism 3.

[0050] Please refer to Figure 3 , a counting switch 37 is installed on the top of the second fixing plate 32. The counting switch 37 can count when the glass bottle passes through the channel of the protection mechanism 3. The signal line of the counting switch 37 is connected to the digital input port of the control component in the control box 6, and the power line is connected to the positive pole of the 24V DC power supply in the control box 6, and the common terminal is connected to the negative pole of the power supply. When the bottle passes through the detection port 35, the bottle body blocks the photoelectric signal of the counting switch 37 and sends a signal to the control component for counting.

[0051] Please refer to Figure 4 , the limiting mechanism 8 includes an actuating cylinder 81 installed on the top of the mounting seat 5 and a limiting ejector rod 82 connected to the movable end of the actuating cylinder 81. The limiting ejector rod 82 extends to the limiting port 36.

[0052] Please refer to Figure 4 , the dial indicator 93 includes a dial indicator main body 931 and a contact rod 932 installed on the dial indicator main body 931. The contact member includes a wheel frame 934 and a contact wheel 935 rotatably installed on the wheel frame 934. One side of the wheel frame 934 is fixedly connected to a sleeve 936 that can be sleeved on the contact rod 932, and the sleeve 936 is fixed to the end of the contact rod 932 by screws.

[0053] Please refer to Figure 3 and Figure 4, the moving part includes clamps 94 connected to both sides of the dial indicator body 931. The top of the clamp 94 is connected to a positioning ring 96 through a connecting rod 95. The positioning ring 96 is slidably connected to the long rod 34. A positioning screw 97 is threadedly connected to the positioning ring 96. The top end of the positioning screw 97 is connected to a positioning knob, and the bottom end of the positioning screw 97 extends into the positioning ring 96 and is connected to an anti-slip pad. By releasing the pressing of the positioning screw 97 on the long rod 34, the positioning ring 96 can slide and adjust its position on the long rod 34, which also facilitates subsequent disassembly.

[0054] Please refer to Figure 2 , a push-button switch is provided on the control box 6. The normally open contact of the push-button switch is connected to the digital input port of the control component. When the operator presses the push-button switch, the control component executes a reset program to clear the alarm status, and the actuating cylinder 81 is in a retracted state. A power supply, a relay, a solenoid valve, and a control component are installed in the control box 6. The solenoid valve drives the actuating cylinder 81 to work. The solenoid valve coil is connected to the control component through the relay. When the proximity switch 92 is triggered, the solenoid valve is de-energized, and the actuating cylinder 81 is in a retracted state, and the limit ejector rod 82 does not participate in the conveying. When the proximity switch 92 is not triggered, the solenoid valve is energized, the actuating cylinder 81 works and is ventilated, and the actuating cylinder 81 extends to intercept defective bottles. Detection, alarm, and limit actions are integrally controlled by the control box 6.

[0055] Among them, the power supply can be a Delta 24V switching power supply, the alarm lamp 7 is a rotating warning lamp LTE-1101J-DC24V red, the proximity switch 92 is a proximity switch E2E-X2E1-Z DC24V Omron, and the intermediate relay NU4N-GSDC24V with a base PYF14A-E Omron.

[0056] Furthermore, the thickness of the first fixing plate 31 and the second fixing plate 32 is 0.6 - 1 mm; taking into account both lightweight and strength, reducing vibration interference with the detection accuracy.

[0057] The working principle of the present invention is as follows: During normal production, the glass bottles are transported uniformly through the conveyor belt 12. The four groups of symmetric guiding mechanisms 2 cooperate to flexibly guide the glass bottles to ensure that they move in a straight line, avoiding deviation or collision damage. The glass bottles enter the detection channel formed by the first fixing plate 31 and the second fixing plate 32 in the protection mechanism 3. A normal bottle body can pass through smoothly. The product presses against the contact part at the contact end of the dial indicator 93, and the overall rod part at the contact end of the dial indicator 93 retracts backward (0.2 - 0.3 mm), touches the proximity switch 92, and the proximity switch 92 lights up. The bottle passes through smoothly, and this product is regarded as a qualified product;

[0058] When a product with a slightly sunken glass bottle body (0.3 - 0.5 mm) passes through the guard plate, the contact end of the dial indicator 93 contacts the concave surface. The entire rod part of the contact end of the dial indicator retreats backward (0.4 - 0.5 mm). The distance between the entire rod part of the contact end and the proximity switch 92 is too far, and the proximity switch 92 cannot sense it, so the light is off and no signal is received. At the same time, the solenoid valve is energized and works normally. The limiting mechanism 8 catches the defective bottle with a sunken body, and the alarm lamp 7 displays an alarm simultaneously. The product on the conveyor belt 12 cannot pass through normally. At this time, the operator will come to the site and press the push button switch, take out the defective bottle and use special equipment to detect whether the bottle is a qualified one. If it is unqualified, it will be scrapped according to the mold number and the production personnel will be notified for handling;

[0059] The present invention can detect regular square bottles and special-shaped bottles, and is applicable to industries such as beverages, medical treatment, and cosmetics.

[0060] The above are only the preferred embodiments of the present invention, and are not limitations to the present invention in other forms. Subsequently, an AI vision detection system can be upgraded and added for automatic rejection, and a digital system can be used to achieve higher precision, higher efficiency, and intelligence, improving the detection accuracy of glass bottle defects and realizing fully automated control detection. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
