Description

Technical Field

[0001] The invention belongs to the technical field of needle cylinder forming machines, in particular to a program-controlled multifunctional needle cylinder forming machine and a forming method. Background Art

[0002] Most of the syringe forming machines currently in use are composed of Part A and Part B mounted on the machine body, and a corresponding revolution drive assembly and rotation drive assembly mounted on the lower part of the machine body for controlling the revolution and rotation of Part A and Part B chucks. The bottle unloading position of Part A corresponds to the bottle receiving position of Part B. Part A includes the Part A chuck assembly mounted on the machine body, and the Part A heating assembly, sizing and pressing assembly, bottle length setting assembly, and explosive breaking assembly mounted on the chuck body of the Part A chuck assembly; Part B includes the Part B chuck assembly mounted on the machine body, and the bottle receiving assembly, Part B heating assembly, flanging assembly, edge straightening assembly, trimming assembly, flat bottom assembly, and Part B bottle unloading assembly mounted on the chuck body of the Part B chuck assembly. This forming machine completely controls the syringe production process using mechanical transmission control. This completely mechanical transmission control method has the following disadvantages:

[0003] One issue is the low positioning accuracy of the mechanical components. Because all drive control mechanisms utilize mechanical transmission, the machining positioning accuracy of parts A and B is low, as is the positioning accuracy of the revolution indexing lock and rotation drive. This impacts machining positioning accuracy and results in low overall product quality.

[0004] The second is low production efficiency. The mechanical transmission control method is not suitable for the production needs of fully automatic program control, resulting in low output and low production efficiency.

[0005] The third is that the overall structure is complex, the machining of parts requires high precision, and production and manufacturing are difficult.

[0006] Fourth, the mechanical components have poor adjustability. Due to the mechanical transmission control method, it is difficult to flexibly adjust parts A and B, as well as the various components involved in revolution and rotation. It is also difficult to adjust the precision of each drive component, making the assembly and debugging of the entire equipment difficult. Summary of the Invention

[0029] The servo cylinder driving the chuck A to open sends a feedback signal to the control unit, which then controls the fixed-length drive servo cylinder to reset via the fixed-length drive.

[0030] When the fixed-length drive servo cylinder returns to its position, the fixed-length drive sends a feedback signal indicating that it has returned to its position to the control unit.

[0064] Due to the adoption of the above technical solution, the program-controlled multifunctional needle forming machine of the present invention has the following beneficial effects compared with the prior art:

[0065] (1) The present invention is an improvement to the existing needle cylinder forming machine. The main improvement is to improve the mechanical transmission control method of the original needle cylinder forming machine for part A, part B, and revolution and rotation to a program-controlled drive control method. The program-controlled drive control method has the following advantages:

[0066] First, it facilitates high-precision setup and adjustment of various drive components. This includes setting and adjusting the speed and position of the revolution indexing lock and rotation, the speed of the cutter, spray, and knocking during the explosive-breaking process, the lifting speed and opening and closing position of the chuck during bottle reception in Section B, the depth and angle of the flanging, the closing speed of the trimming mold, the trimming position, the opening and closing time of the chuck during bottle unloading in Section B, and the positioning and speed of the robot gripper. Furthermore, these settings and adjustments provide a convenient and intuitive display of the setup and adjustment parameters, greatly facilitating the installation and commissioning of the needle forming machine.

[0067] Secondly, the drive positioning accuracy of each drive mechanism is high. By controlling the servo cylinder, servo motor or solenoid valve through the controller, high-precision drive positioning control of the syringe production process is easily achieved. At the same time, the high-precision coordination between the drive control mechanisms is also improved, thereby greatly improving the accuracy of the entire syringe forming machine and effectively ensuring the quality of the syringe barrel.

[0068] The third is to improve production efficiency. The program-controlled control method is adopted to meet the production needs of fully automated program control, increase product output, and greatly improve production efficiency.

[0069] Fourth, it improves product quality. That is, after the cylinder enters the B part, it undergoes flanging, trimming, trimming, bottom flattening, and multiple heating processes, which increases the product's process performance and effectively ensures product quality.

[0070] Fifth, it can be used in the production of a variety of syringes, such as prefilled or cartridge bottles.

[0071] (2) The present invention sets a secondary fixed-length assembly and sets a fixed-length process after the cylinder is input into the B chuck and before the cylinder is processed. This can effectively avoid the situation where part of the cylinder fails to accurately fall to a specific position in the clamping claw of the B chuck due to the influence of friction and centripetal force. It can effectively ensure that the length of the cylinder falling into the B chuck is consistent, and ensure the accuracy of the position of the cylinder clamped by the B part, thereby ensuring the processing accuracy of the cylinder in subsequent processing steps, improving product quality, and reducing unqualified products.

[0072] The invention is used for producing glass bottles for medicine packaging, such as pre-filled or cartridge bottles. BRIEF DESCRIPTION OF THE DRAWINGS

[0085] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and understand the present invention and are not intended to limit the present invention.

[0086] Example 1 A program-controlled multifunctional needle forming machine

[0087] The present invention is an improvement to the existing needle cylinder forming machine. The main improvement is to change the mechanical transmission control mode of the original needle cylinder forming machine for part A, part B, revolution and rotation into a program-controlled drive control mode.

[0088] This embodiment includes a mechanical transmission structure and a program control system.

[0089] 1. Mechanical transmission structure

[0090] The mechanical transmission structure includes Part A 1 and Part B, which are correspondingly mounted on the machine body, and a revolution drive assembly and a rotation drive assembly which are correspondingly mounted on the lower part of the machine body. The bottle unloading position of Part A corresponds to the bottle receiving position of Part B. Part A 1 includes the Part A chuck assembly mounted on the machine body, and the Part A heating assembly, sizing and pressing assembly, bottle body length-fixing assembly, and explosive breaking assembly which are correspondingly mounted on the controlled chuck body of the Part A chuck assembly; Part B includes the Part B chuck assembly mounted on the machine body, and the bottle receiving assembly, secondary length-fixing assembly, Part B heating assembly, flanging assembly 2, edge straightening assembly 3, trimming assembly 10, flat bottom assembly 101, and Part B bottle unloading assembly 4 which are correspondingly mounted on the controlled chuck body of the Part B chuck assembly. The axes of the Part A chuck and the Part B chuck are both vertical lines, which is a vertical needle forming machine. The composition and mutual connection relationship of the above-mentioned parts are described in detail below:

[0091] (1) Revolution drive assembly and rotation drive assembly

[0092] The revolution drive assembly can utilize the existing structure used to control the revolution of parts A 1 and B. It consists of a part A revolution drive mechanism and a part B revolution drive mechanism. The outputs of the part A revolution drive mechanism and the part B revolution drive mechanism are connected to the control inputs of the part A chuck assembly and the part B chuck assembly, respectively. The part A revolution drive mechanism utilizes the existing direct indexing drive device of a neutral bottle control machine. During operation, the part A direct-drive indexing servo motor 111 directly indexes the part A chuck plate and controls the working position. The part B indexing drive motor 241 also indexes the part B chuck plate and controls the working position.

[0093] The rotation drive assembly can adopt the structure used to control the rotation of part A 1 and part B in the existing technology, and is composed of a part A rotation drive mechanism and a part B rotation drive mechanism. When working, the part A 1 rotation servo motor and the part B rotation servo motor 251 respectively realize the control of the rotation of part A 1 and the rotation of part B.

[0094] (II) Part A 1

[0095] The components of part A 1, including the part A chuck assembly, the part A heating assembly, the bottle body length fixing assembly, the diameter-making and pressing mouth assembly, and the explosive breaking assembly, can adopt existing technologies.

[0096] The sizing and notching assembly may include a prior art bottle making machine bottle mouth extrusion control device assembled on the machine body and driven by a mold servo motor 131, left and right half molds of the bottle mouth connected to the power output end of the bottle mouth extrusion control device, and a core driven by a core shaft servo motor 141.

[0097] The explosive-breaking assembly is used to cold-explode the lower end of the material pipe from the upper portion to form a barrel with a finished bottleneck. The explosive-breaking assembly includes a correspondingly assembled cutter connected to the power output of the cutter stepper motor 181 for cutting the barrel, a hydrogen lamp, a pipe-supporting clamp connected to the power output of the rotating bottle-supporting cylinder 191, a spray nozzle controlled by a spray valve 201, and a percussion hammer connected to the power output of the hammer drive cylinder 211. During the explosive-breaking process, the cutter marks the barrel; the pipe-supporting clamp holds the lower portion of the barrel cut by the cutter to prevent it from falling; the nozzle sprays cooling spray onto the barrel, and the percussion hammer strikes the barrel, transferring the barrel, which has been calibrated and notched, into section B.

[0098] (III) Part B

[0099] The components of part B, including the part B chuck assembly, bottle receiving assembly, part B heating assembly, flanging assembly 2, edge trimming assembly 3, trimming assembly 10, flat bottom assembly 101 and part B bottle unloading assembly 4, all adopt existing technologies. The part B processing structure is composed of the bottle receiving assembly, secondary length fixing assembly, part B heating assembly, flanging assembly 2, part B heating assembly, edge trimming assembly 3, part B heating assembly, trimming assembly 10, part B heating assembly, flat bottom assembly 101 and part B bottle unloading assembly 4, which are arranged in sequence.

[0100] The bottle receiving assembly can be a chuck lifting and opening and closing mechanism in the prior art, which controls the controlled B-part chuck in the bottle receiving position to lift and open to take out the barrel through the B-part chuck lifting drive servo cylinder 221 and the B-part chuck opening drive servo cylinder 231 respectively.

[0101] The secondary length-fixing assembly is used to fix the length of the barrel input to Section B before the Section B processing steps. The secondary length-fixing assembly includes a secondary length-fixing chuck control mechanism corresponding to the controlled Section B chuck and a positioning pad 5 fixed within the jaws of the Section B chuck for length-fixing. The secondary length-fixing chuck control mechanism includes a secondary length-fixing servo motor 261, a screw 6 fixedly connected to the power output end of the secondary length-fixing servo motor 261, an opening and closing block 7 fixedly connected to the power output end of the screw 6 for controlling the lifting and closing of the chuck, and a clutch opening block for controlling the clutch opening and closing of the chuck. The opening and closing block 7 is positioned corresponding to the opening and closing control end of the controlled Section B chuck, and the clutch opening block 8 is positioned corresponding to the clutch opening and closing control end of the controlled Section B chuck. When performing the secondary length-fixing process, the secondary length-fixing servo motor 261 drives the screw 6 to rotate, and the screw 6 drives the opening and closing block and the clutch opening block 8 to move in a straight line together to open the B part chuck and the B part chuck clutch respectively, so that the B part chuck opens and stops rotating. At this time, the cylinder is positioned downward on the positioning pad 5 to complete the secondary length-fixing of the cylinder.

[0102] The flanging assembly 2 is used to turn the mouth of the barrel outward. It includes a flanging extension servo motor 271 for driving the linear movement of the flanging shaft, a flanging rotation servo motor 281 connected to the power output of the flanging extension servo motor 271 to control the rotation of the flanging shaft, and a flanging shaft connected to the power output of the flanging rotation servo motor 281. During the flanging process, the flanging extension servo motor 271 drives the flanging shaft into the barrel, while the flanging rotation servo motor 281 rotates the flanging shaft to complete the outward flanging.

[0103] The trimming assembly 3 is used to trim the outward-turned edges after the flanging process.
