Description

Technical Field

[0001] The present invention relates to the technical field of glass bottle production and manufacturing, and in particular to a weight detection and control process for glass bottles of a row machine. Background Art

[0002] The row machine is mainly used in the glass bottle and can manufacturing industry. The invention of the row machine has realized the automated production of the glass bottle and can industry, thereby improving production efficiency, reducing labor costs and accelerating industry development.

[0003] The glass raw materials are fired in a kiln to form molten glass liquid, and the molten glass liquid flows through a material channel to a material basin of a glass feeding device, and molten glass droplets flow out from a material outlet of the material basin, and the material basin is made of refractory and high-temperature resistant materials; after the glass droplets are cut by the shearing mechanism, they enter the dividing mechanism of the glass bottle forming device, and the glass droplets are distributed to each material guide trough in sequence by the dividing mechanism, and then pass through the corresponding primary mold mechanism, turning mechanism, molding mechanism, bottle moving mechanism, air cooling mechanism, bottle shifting mechanism, and glass bottle conveyor belt mechanism in sequence; the primary mold mechanism is used to process the glass droplets into a prototype blank, the turning mechanism is used to turn the prototype blank from the primary mold mechanism into the molding mechanism, the molding mechanism is used to blow the prototype blank into a glass bottle, the bottle moving mechanism is used to move the glass bottle from the molding mechanism to the air cooling mechanism, the air cooling mechanism is used to cool the glass bottle, the bottle shifting mechanism is used to move the glass bottle from the air cooling mechanism to the glass bottle conveyor belt mechanism, and the glass bottle conveyor belt mechanism transports the glass bottle to the annealing furnace.

[0004] The weight of the glass droplets flowing out of the material box is determined according to the actual specifications of the glass bottles to be produced. Due to factors such as machine damage, aging, and loss of glass droplets during transportation, the glass liquid reaching the molding mechanism may not meet or exceed the blowing requirements, making the blown glass bottles too thin or too thick, resulting in the weight of the finished glass bottles not meeting the standards or defects on the bottle body, thereby increasing production costs. Generally, the material discharge method of the material basin is manually adjusted, and the glass feeding device has to stop working during manual adjustment, which is inefficient.

[0005] Therefore, after the glass bottles are manufactured by the array machine, it is necessary to check whether the weight of the glass bottles meets the standards to ensure the production quality of the glass bottles. When the weight of the glass bottles does not meet the standards, it is necessary to quickly control the weight of the glass droplets flowing out of the discharge port of the material basin. The more glass droplets flowing out of the material basin, the heavier the glass droplets, and the fewer glass droplets flowing out of the material basin, the lighter the glass droplets.

[0059] An embodiment of the present invention provides a weight detection and control process for glass bottles of a row machine, which overcomes the shortcomings of the background technology that the weight of the finished glass bottles does not meet the standards and the production cost is high. It realizes the technical effect of detecting the weight of the glass bottles, comparing whether they meet the standards, and controlling the weight of the glass droplets flowing out of the discharge port of the material basin, thereby ensuring the production quality of the glass bottles and reducing production costs.

[0060] The overall idea of ​​the technical solution of the embodiment of the present invention is as follows:

[0061] The discharge control mechanism of the glass feeding device is used to control the glass droplets flowing out of the discharge port of the material basin. After the shearing mechanism cuts off the glass droplets, the glass droplets pass through the dividing mechanism, the initial mold mechanism, the flipping mechanism and the molding mechanism in sequence, and are formed into glass bottles in the molding mechanism. The glass bottles pass through the bottle moving mechanism, the air cooling mechanism, and the bottle pushing mechanism in sequence and enter the glass bottle conveyor belt mechanism. The glass bottle grabbing device grabs the glass bottle from the glass bottle conveyor belt mechanism and places it on the electronic scale for weighing. The weighing value of the electronic scale, the upper limit threshold of the glass bottle weight, the lower limit threshold of the glass bottle weight, and the standard value of the glass bottle weight are compared. When the weight of the glass bottle is too heavy, the discharge control mechanism reduces the weight of the glass droplets. When the weight of the glass bottle is too light, the discharge control mechanism increases the weight of the glass droplets.

[0062] When the weighing value of the glass bottle is between the set upper and lower weight thresholds of the glass bottle, the weight of the glass bottle meets the standard; when the weighing value of the glass bottle is not between the set upper and lower weight thresholds of the glass bottle, the weight of the glass bottle does not meet the standard.

[0063] The glass feeding device, glass bottle forming device and glass bottle grabbing device are first in the debugging state. After the weight of the glass bottle is adjusted and corrected between the upper and lower weight thresholds of the glass bottle, the glass feeding device, glass bottle forming device and glass bottle grabbing device enter the normal working state.

[0064] The computer obtains the weighing value of the electronic scale, saves it automatically, compares the weighing value of the electronic scale in real time, and automatically controls the glass dripping out of the material basin through the discharge control mechanism of the glass feeding device, automatically corrects the weight of the glass bottle, and ensures the quality of the glass bottle.

[0065] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0066] See Figures 1 to 12 , a preferred embodiment of the present invention.

[0067] A process for detecting and controlling the weight of glass bottles of a row machine includes the following steps:

[0068] S1. Set an upper weight threshold, a lower weight threshold, and a standard weight value for the glass bottle; input the upper weight threshold, the lower weight threshold, and the standard weight value for the glass bottle into a computer 33; the standard weight value for the glass bottle is the average of the upper weight threshold and the lower weight threshold for the glass bottle.

[0069] S2, the glass feeding device 1 is in the debugging state;

[0070] The glass feeding device 1 includes a material basin 11, a discharge control mechanism 12 and a shearing mechanism. The discharge control mechanism 12 causes the molten glass drop 5 to flow out of the discharge port of the material box, and the shearing mechanism shears the glass drop 5 at the discharge port of the material box. The more glass drop 5 flows out of the material basin 11, the heavier the glass drop 5, and the less glass drop 5 flows out of the material basin 11, the lighter the glass drop 5.

[0071] S3, the glass bottle forming device 2 is in the debugging state;

[0072] The glass bottle forming device 2 includes a material distribution mechanism 21, a blank mold mechanism 22, a turning mechanism 23, a molding mechanism 24, a bottle moving mechanism 25, an air cooling mechanism 26, a bottle pushing mechanism 27 and a glass bottle conveyor mechanism 28. The cut glass drop material 5 passes through the material distribution mechanism 21, the blank mold mechanism 22, the turning mechanism 23 and the molding mechanism 24 in sequence, and is formed into a glass bottle 51 in the molding mechanism 24. The glass bottle 51 passes through the bottle moving mechanism 25, the air cooling mechanism 26 and the bottle pushing mechanism 27 in sequence and enters the glass bottle conveyor mechanism 28.

[0073] S4, the glass bottle grabbing device 4 is in the debugging state;

[0074] The glass bottle grabbing device 4 grabs the glass bottle 51 from the glass bottle conveyor belt mechanism 28 and then places the glass bottle 51 on the electronic scale 32;

[0075] S5. The electronic scale 32 displays the weighing value; the computer 33 is electrically connected to the electronic scale 32, and the display screen of the computer 33 displays the weighing value of the electronic scale 32. The computer 33 compares the weighing value with the lower limit threshold of the glass bottle weight and the upper limit threshold of the glass bottle weight;

[0076] The display screen of the computer 33 displays the weighing value of the electronic scale 32, and the computer 33 automatically saves the weighing value; the electronic scale 3232 sends the weighing value to the computer 33, and the computer 33 obtains and displays the current weight value of the glass bottle 51. After seeing the display screen of the computer 33, the staff can determine whether the weight of the glass bottle 51 meets the standard.

[0077] S6. When the weighing value is lower than the lower limit threshold of the glass bottle weight, go to S7; when the weighing value is higher than the upper limit threshold of the glass bottle weight, go to S8; when the weighing value is between the lower limit threshold of the glass bottle weight and the upper limit threshold of the glass bottle weight, go to S9;

[0078] S7, the computer 33 is electrically connected to the discharge control mechanism 12, and the discharge control mechanism 12 increases the weight of the glass gob 5. The increased weight is the difference between the standard weight value of the glass bottle and the weighed value. The computer 33 calculates the difference between the standard weight value of the glass bottle and the weighed value, and then goes to S2;

[0079] S8, the computer 33 is electrically connected to the discharge control mechanism 12, and the discharge control mechanism 12 reduces the weight of the glass gob 5. The reduced weight is the difference between the weighing value and the standard weight value of the glass bottle. The computer 33 calculates the difference between the standard weight value of the glass bottle and the weighing value, and then goes to S2;

[0080] S9. Set parameters for glass bottle grabbing and spot checking and a threshold for the number of unqualified products. Input the parameters and threshold into the computer 33. The parameters for glass bottle grabbing and spot checking can be set to grab and weigh one glass bottle every six bottles passed. The parameters for glass bottle grabbing and spot checking depend on specific production conditions. The threshold for the number of unqualified products can be set based on actual production conditions, for example, three.

[0081] S10, the glass feeding device 1 and the glass bottle forming device 2 are both in normal working condition;

[0082] S11, the computer 33 is electrically connected to the glass bottle grabbing device 4, the glass bottle grabbing device 4 is in normal working condition, grabs glass bottles from the glass bottle conveyor mechanism 28 according to the glass bottle grabbing and spot checking parameters, and then places the glass bottles on the electronic scale 32;

[0083] S12, when the weighing value of the electronic scale 32 is not between the lower limit threshold of the glass bottle weight and the upper limit threshold of the glass bottle weight, the number of glass bottles with unqualified weight is recorded;

[0084] S13. When the number of glass bottles with unqualified weight does not exceed the unqualified number threshold, go to S10; when the number of glass bottles with unqualified weight exceeds the unqualified number threshold, go to S14;

[0085] S14: The glass feeding device 1, the glass bottle forming device 2, and the glass bottle grabbing device 4 all stop running and finally enter a debugging state.

[0086] In an embodiment of the present invention, the glass bottle weighing device 3 includes an operating table 31, an electronic scale 32, a computer 33, a weight increase button 34 and a weight decrease button 35. The operating table 31 is adjacent to the glass bottle conveyor belt mechanism 28. The electronic scale 32 is fixedly installed on the operating table 31. The electronic scale 32 is electrically connected to the computer 33. The display screen of the computer 33 displays the weighing value of the electronic scale 32. The computer 33 automatically saves the weighing value. The weight increase button 34 and the weight decrease button 35 are both fixedly set on the operating table 31. The weight increase button 34 and the weight decrease button 35 are both electrically connected to the discharge control mechanism 12. When the staff presses the weight increase button 34 once, the weight increase button 34 sends a pulse signal to the discharge control mechanism 12, and the discharge control mechanism 12 increases the unit weight of the glass gob 5 by one unit. When the weight increase button 34 is pressed multiple times, the glass gob 5 increases multiple unit weights. The unit weight depends on the actual situation, for example, the unit weight is one gram. When the operator presses the weight reduction button 35 once, the weight reduction button 35 sends another pulse signal to the discharge control mechanism 12, thereby reducing the weight of the glass gob 5 by one unit. The weight increase button 34 and the weight reduction button 35 are used by the operator to manually control the discharge control mechanism according to actual conditions.

[0087] The glass bottle grabbing device 4 is used to grab a glass bottle 51 from the glass bottle conveyor belt mechanism 28, move the glass bottle 51 to the top of the weighing hole 311, and then place the glass bottle 51 on the electronic scale 32. The electronic scale 32 sends the weighing value to the computer 33, which obtains and displays the current weight value of the glass bottle 51. After viewing the display screen of the computer 33, the staff can determine whether the weight of the glass bottle 51 meets the standard. If the weight of the glass bottle 51 does not meet the standard, the staff operates the weight increase button 34 and the weight decrease button 35 to send a signal to the discharging control mechanism 12, which quickly controls the weight of the glass gob material 5 flowing out of the discharging port of the material basin 11, thereby adjusting and correcting the weight of the glass bottle 51. The operation is convenient.

[0088] In one implementation of the present invention, the glass bottle grasping device 4 is a pair of tweezers 41. The operating table 31 includes a weighing table having a communicating weighing hole 311 and a cavity 312. The electronic scale 32 is placed in the cavity 312. The weighing hole 311 can accommodate one glass bottle 51, and the tweezers 41 can be placed on the weighing table. A staff member uses the tweezers 41 to grasp the glass bottle 51 for weighing, manually checking the weight of the glass bottle 51.

[0089] In another implementation of the present invention, the glass bottle grasping device 4 includes a guide rail 42, a clamping claw 43, a clamping control mechanism 44, a support frame 45, a lifting control mechanism 46, a movement control mechanism 47, and a slide 48. One end of the guide rail 42 is fixedly disposed above the glass bottle conveyor belt mechanism 28, and the other end of the guide rail 42 is fixedly disposed above the electronic scale 32. The slide 48 is connected to the guide rail 42 via the movement control mechanism 47, the support frame 45 is connected to the slide 48 via the lifting control mechanism 46, and the clamping claw 43 is connected to the support frame 45 via the clamping control mechanism 44. The clamping claw 43 is used to grasp the glass bottle 51. The clamping control mechanism 44 is a pneumatic finger, the lifting control mechanism 46 is a telescopic cylinder, and the movement control mechanism 47 is a ball screw.

[0090] The gripping control mechanism 44 of the glass bottle grabbing device 4 causes the gripping claw 43 to grip and release the glass bottle 51. The lifting control mechanism 46 is used to lift and lower the glass bottle 51. The movement control mechanism 47 is used to move the gripped glass bottle 51 from the glass bottle conveyor mechanism 28 to the electronic scale 32, thereby achieving automatic gripping and weighing. According to pre-set control instructions, the glass bottle grabbing device 4 first moves above the glass bottle conveyor mechanism 28. The gripping claw 43 then grips the glass bottle 51 downward. The gripping claw 43 then lifts the glass bottle 51 and moves it from the glass bottle conveyor mechanism 28 to the electronic scale 32. The glass bottle 51 is then placed on the weighing hole 311. During the weighing process on the electronic scale 32, the gripping claw 43 releases the glass bottle 51. After weighing is completed, the gripping claw 43 re-grabs the glass bottle 51, lifts it from the electronic scale 32, removes it, and finally discards it into the glass bottle disposal port 36.

[0091] The glass bottle grabbing device 4 also includes a glass bottle detection sensor 49, a counter 410, and a grabbing controller 411. The glass bottle detection sensor 49 is mounted on the glass bottle conveyor mechanism 28 and is electrically connected to the counter 410, which is in turn electrically connected to the grabbing controller 411. The grabbing controller 411 controls the operating states of the clamping control mechanism 44, the lifting control mechanism 46, and the movement control mechanism 47. The glass bottle detection sensor 49 may be a photoelectric sensor. Each time a glass bottle 51 passes through the glass bottle detection sensor 49, the sensor sends a signal to the counter 410, which counts the number of bottles that have passed. When the number reaches a glass bottle grabbing and spot-checking parameter, the counter 410 triggers the grabbing controller 411, which activates the glass bottle grabbing device 4 to perform a weight check of a fixed number of glass bottles. The grabbing controller 411 is a PLC controller. The parameters for the random inspection of glass bottles can be set to grab one glass bottle for weighing every six glass bottles passed; the parameters for the random inspection of glass bottles depend on the specific production situation.

[0092] The operating table 31 is also provided with a glass bottle discarding port 36, and the glass bottle grabbing device 4 is also used to throw the weighed glass bottles 51 into the glass bottle discarding port 36. The glass bottle discarding port 36 is communicated with the waste field outside the production workshop through a conveying pipeline.

[0093] The discharging control mechanism 12 includes a punching head 121, a punching arm 122, a punching box 123, a punching servo motor 124, a steering controller 125, a driving wheel 126, a driven wheel 127, a transmission belt 128, a nut screw pair 129, a transmission frame 1210, a main shaft 1211 and a guide shaft 1212. The punching box 123 is provided with a lifting hole and a guide hole. The main shaft 1211 is slidably connected to the lifting hole, and the guide shaft 1212 is slidably connected to the guide hole. The upper end of the main shaft 1211 and the upper end of the guide shaft 1212 are fixedly connected to the punching arm 122. The punching arm 122 is also fixedly connected to the punching head 121. The screw of the nut screw pair 129 is rotatably connected to the inside of the punching box 123. The nut 129 is fixedly connected to one end of the transmission frame 1210, the other end of the transmission frame 1210 is fixedly connected to the main shaft 1211, the screw of the nut screw pair 129 is fixedly connected to the center of the driven wheel 127, the output shaft of the punching servo motor 124 is fixedly connected to the center of the driving wheel 126, the body of the punching servo motor 124 is fixedly connected to the punching box 123, the driving wheel 126 and the driven wheel 127 are connected through the transmission belt 128, the steering controller 125 is electrically connected to the punching servo motor 124, the weight increase button 34 and the weight reduction button 35 are both electrically connected to the steering controller 125, and the punching head 121 is used to punch out the molten glass in the material basin 11 to form the glass drop material 5.

[0094] The steering controller 125 is a PLC controller used to adjust the direction and number of revolutions of the punching servo motor 124. For example, when the servo motor outputs forward rotation, the main shaft 1211 moves upward through the driving wheel 126, the transmission belt 128, the driven wheel 127, the nut screw pair 129, and the transmission frame 1210. The more revolutions the servo motor outputs in the forward direction, the more the main shaft 1211 moves upward. When the servo motor outputs reverse rotation, the main shaft 1211 moves downward. The more revolutions the servo motor outputs in the reverse direction, the more the main shaft 1211 moves downward. The punching servo motor 124 drives the main shaft 1211, the punching arm 122, and the punching head 121 to move up and down repeatedly. In this way, the steering controller 125 can adjust the stroke 14 of the main shaft 1211 and the punching head 121, thereby adjusting the outflow of the glass liquid in the material basin 11. When the staff presses the weight increase button 34 once, the weight increase button 34 sends a pulse signal to the steering controller 125, and the steering controller 125 increases the number of revolutions of the forward rotation of the punching servo motor 124 by one unit, so that the upward displacement of the punching head 121 increases by one unit length, the stroke 14 increases, and the glass drop 5 formed after the punching head 121 punches out the molten glass in the material basin 11 increases by one unit weight accordingly; when the staff presses the weight reduction button 35 once, the weight reduction button 35 sends another pulse signal to the steering controller 125, and the steering controller 125 reduces the forward rotation of the punching servo motor 124 by one unit revolution, and the stroke 14 reduces, so that the downward displacement of the punching head 121 reduces by one unit length, and the glass drop 5 formed after the punching head 121 punches out the molten glass in the material basin 11 reduces by one unit weight accordingly.

[0095] The glass bottle weighing device 3 also includes an alarm 37, which is electrically connected to the computer 33. The computer 33 stores an upper and lower weight threshold for the glass bottles. When the weight value of the electronic scale 32 is not between the upper and lower weight thresholds, the computer 33 causes the alarm 37 to sound an alarm. The beneficial effect of this is that the computer 33 automatically compares the weight value of the electronic scale 32 with the upper and lower weight thresholds for the glass bottles, and promptly triggers the alarm 37 to alert the staff of any abnormal glass bottle weight.

[0096] The computer 33 generates and displays a graph showing the weight values ​​changing over time and saves the weight values ​​and weighing time in an Excel spreadsheet. The beneficial effect here is that it is convenient for the staff to understand the weight changes of the glass bottles during the production process and provide a reference for later machine maintenance.

[0097] When the weighing value of the electronic scale 32 is lower than the lower limit threshold of the glass bottle weight, the computer 33 increases the weight of the glass drop 5 through the discharge control mechanism 12, and the increased weight is the difference between the standard value of the glass bottle weight and the weighing value; the computer 33 automatically calculates the increased weight and adjusts the weight of the glass bottle to the standard value of the glass bottle weight, which helps to reduce the number of alarms. The increased weight is converted into a pulse signal in the computer 33 and sent to the steering controller 125 of the discharge control mechanism 12. The steering controller 125 increases the number of forward rotations of the punching servo motor 124 accordingly, increases the upward displacement of the punching head 121 accordingly, and increases the weight of the glass drop 5 accordingly.

[0098] When the weighing value of the electronic scale 32 is higher than the upper limit threshold of the glass bottle weight, the computer 33 reduces the weight of the glass drop 5 through the discharge control mechanism 12, and the reduced weight is the difference between the weighing value and the standard value of the glass bottle weight; the computer 33 automatically calculates the reduced weight and adjusts the weight of the glass bottle to the standard value of the glass bottle weight, which helps to reduce the number of alarms. The reduced weight is converted into another pulse signal in the computer 33 and sent to the steering controller 125 of the discharge control mechanism 12. The steering controller 125 reduces the number of forward rotations of the punching servo motor 124 accordingly, reduces the upward displacement of the punching head 121 accordingly, and reduces the weight of the glass drop 5 accordingly.

[0099] The computer 33 is also electrically connected to the glass bottle grabbing device 4. It stores parameters for checking glass bottle grabbing and random inspections, and the glass bottle grabbing device 4 performs its grabbing operations according to these parameters. A staff member modifies these parameters using the keyboard of the computer 33. The computer 33 then sends these parameters to the grabbing controller 411, which controls whether the glass bottle grabbing device 4 is activated.

[0100] The computer 33 sends the weight increase or decrease signal to the discharging control mechanism in real time, quickly adjusts the weight of the glass bottle 51, and quickly changes the glass bottle grabbing and random inspection parameters by the computer 33, with a high degree of automation.

Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included within the scope of protection of the claims of the present invention.
