Description

Technical Field

[0001] This utility model belongs to the field of gripping mechanism technology, specifically relating to a bottle and can gripping mechanism. Background Technology

[0002] Bottle and can gripping mechanisms are common end effectors in industrial automation, particularly in the food, beverage, chemical, and pharmaceutical industries. Their core task is to efficiently, stably, and without damage grip and move various bottles and cans on the production line. Bottle and can gripping mechanisms are a crucial link in automated production lines. From simple and reliable pneumatic grippers to efficient and non-destructive vacuum suction cups, and advanced and flexible adaptive grippers, each solution has its unique advantages and applicable scenarios. The correct selection can greatly improve production efficiency, stability, and product qualification rate. The main types of bottle and can gripping mechanisms include pneumatic grippers, pneumatic internal support grippers, vacuum suction grippers, flexible adaptive grippers, and hybrid grippers. Among these, the most common is the pneumatic gripper type. Its working principle uses compressed air to drive a cylinder, causing two or more "fingers" to simultaneously open and close, gripping the bottle from the outside of the bottle body or neck.

[0003] However, pneumatic gripper-type bottle and can grasping mechanisms have requirements on the diameter and shape of the bottles and cans, and can only grasp bottles and cans of a single product, resulting in poor versatility and inability to grasp various types of bottles and cans. Therefore, there is an urgent need to design a bottle and can grasping mechanism to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a bottle and can gripping mechanism to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bottle and can gripping mechanism, comprising:

[0006] The mounting frame includes mounting plate one, mounting plate two, and mounting plate three arranged sequentially from top to bottom.

[0017] The technical effects and advantages of this utility model are as follows: This bottle and can gripping mechanism features an advanced design, compact structure, ease of use, and reliable operation. Through the coordinated cooperation of the mounting frame, bottle cap positioning component, gripper lifting component, and gripper gripping component, it can achieve efficient, stable, and non-destructive gripping of bottles and cans of various diameters and shapes.

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

[0026] This utility model provides, for example Figure 1-4 The bottle and can gripping mechanism shown includes:

[0027] The mounting frame 100 includes mounting plate 101, mounting plate 2 102 and mounting plate 3 103 arranged sequentially from top to bottom. The four corners of mounting plate 101, mounting plate 2 102 and mounting plate 3 103 are connected by sliding rods 104. A flange mounting platform 105 is fixed to the top of mounting plate 2 102 and a flange joint 106 is fixed to the top of flange mounting platform 105.

[0028] The bottle cap positioning assembly 200 includes a bottle cap positioning sleeve 201 and a capping cylinder mounting platform 202 fixed to the top of the mounting plate 3 103. The capping cylinder mounting platform 202 has a capping cylinder 203 fixed to its top and a positioning sleeve mounting plate 204 at its bottom. The top end of the bottle cap positioning sleeve 201 passes through the mounting plate 3 103 and is fixedly connected to the positioning sleeve mounting plate 204. The piston rod of the capping cylinder 203 passes through the capping cylinder mounting platform 202 and is fixedly connected to the positioning sleeve mounting plate 204.

[0029] The gripper lifting assembly 300 includes lifting cylinders 301 fixed at the four corners of the bottom of the mounting plate 2 102, and the piston rod of the lifting cylinder 301 is fixedly connected to the mounting plate 3 103.

[0030] The gripper assembly 400 includes a gripper cylinder 401 disposed on the top of the mounting plate 3 103 and grippers 402 disposed on both sides of the mounting plate 3 103. The piston rod of the gripper cylinder 401 is movably connected to the top end of the gripper 402.

[0031] For example, see Figures 1-2 As shown, the slide rod 104 is provided with a slide rod protective sleeve 107. The slide rod protective sleeve 107 is fixedly connected to the mounting plate 102 via a flange. A solenoid valve 108 is fixed on one side of the top of the mounting plate 102, and an electronic connector 109 is fixed on one side of the mounting plate 102.

[0032] In this technical solution, the slide bar protective sleeve 107 can provide effective protection for the slide bar 104, preventing it from being damaged by external factors during operation and extending the service life of the slide bar 104. The solenoid valve 108 is used to control the opening and closing of the air circuit, thereby precisely controlling the action of each cylinder and ensuring that the entire bottle and can gripping mechanism can operate stably according to the predetermined program. The electronic connector 109 is used to realize the transmission of electrical signals and connect with the external control system, accurately transmitting the instructions of the control system to each actuator, thereby realizing the automated control of the bottle and can gripping mechanism.

[0033] For example, see Figures 2-4 As shown, the positioning sleeve mounting plate 204 and the mounting plate 3103 are connected by limiting posts 205. The four limiting posts 205 pass through the four corners of the positioning sleeve mounting plate 204 respectively, and the positioning sleeve mounting plate 204 and the limiting posts 205 are slidably connected.

[0034] In this technical solution, the limiting post 205 provides a stable guide for the positioning sleeve mounting plate 204, ensuring its smooth operation during lifting and lowering without deviation or wobbling. This guarantees the positioning accuracy of the bottle cap positioning sleeve 201 and improves the accuracy and stability of bottle gripping. When the capping cylinder 203 drives the positioning sleeve mounting plate 204 to lift and lower, the positioning sleeve mounting plate 204 slides up and down along the limiting post 205. This sliding connection method ensures both the flexibility of movement of the positioning sleeve mounting plate 204 and restricts its direction of movement, allowing it to lift and lower only in the vertical direction, avoiding horizontal deviation. This ensures that the bottle cap positioning sleeve 201 can accurately position itself to the bottle cap, providing a reliable guarantee for subsequent gripping actions.

[0035] For example, see Figure 4 As shown, the gripper gripping assembly 400 also includes a gripper cylinder mounting base 403 and a gripper mounting base 404. The gripper cylinder mounting base 403 is fixed to the top of the mounting plate 3 103 and is hinged to one end of the gripper cylinder 401. The gripper mounting base 404 is fixed to one side of the mounting plate 3 103 and is hinged to one end of the gripper 402.

[0036] In this technical solution, the gripper cylinder mounting base 403 provides a stable mounting foundation for the gripper cylinder 401 and is connected to the gripper cylinder 401 via a hinge, allowing the gripper cylinder 401 to rotate flexibly within a certain range. Similarly, the gripper mounting base 404 is connected to the gripper 402 via a hinge. This design ensures that the piston rod of the gripper cylinder 401 can drive the gripper 402 to rotate when it extends or retracts, allowing the gripper 402 to support the bottle or can being gripped, thus improving the safety and stability of the gripping process. During actual operation, after receiving instructions from the control system, the gripper cylinder 401 drives the gripper 402 to open and close through the extension and retraction of its piston rod, thereby achieving the gripping and release of the bottle or can. This design enables the gripper gripping assembly 400 to efficiently and stably complete the bottle or can gripping task, improving the overall efficiency and reliability of the bottle or can gripping mechanism.

[0037] For example, the bottle cap positioning sleeve 201 has a positioning cavity (not shown in the figure) that is adapted to the shape of the bottle cap, and the inner wall of the positioning cavity has an elastic buffer layer (not shown in the figure).

[0038] In this technical solution, the design of the positioning cavity ensures that the bottle cap falls accurately into the predetermined position during the positioning process and fits tightly with the shape of the bottle cap, thereby improving the positioning accuracy and stability. The setting of the elastic buffer layer further enhances the reliability and safety of the positioning process. It can play a buffering role when the bottle cap falls into the positioning cavity, avoiding damage to the bottle cap or the bottle cap positioning sleeve 201 due to excessive impact force.

[0039] For example, see Figures 1-2 As shown, a rectangular opening is provided on the mounting plate 2 102. The position of the rectangular opening corresponds to the position of the cover cylinder 203, and the size of the rectangular opening is not smaller than the size of the cover cylinder 203.

[0040] In this technical solution, the rectangular opening provides sufficient space for the cover cylinder 203, ensuring that the cover cylinder 203 will not interfere with the mounting plate 2 102 during operation. It also helps the cover cylinder 203 dissipate heat, preventing its performance and service life from being affected by excessively high temperature due to long-term operation.

[0041] For example, see Figure 2 As shown, there are several bottle cap positioning sleeves 201, which are equidistantly distributed along the central axis of the positioning sleeve mounting plate 204.

[0042] In this technical solution, the arrangement of multiple bottle cap positioning sleeves 201 enables the bottle gripping mechanism to simultaneously position multiple bottles and cans, significantly improving production efficiency. The equidistant distribution along the central axis of the positioning sleeve mounting plate 204 ensures uniform spacing between the bottle cap positioning sleeves 201, guaranteeing accurate positioning of each bottle and can when gripping multiple bottles and cans, thus avoiding gripping failures or bottle / can damage caused by uneven positioning. In actual production, the number and distribution of the bottle cap positioning sleeves 201 can be flexibly adjusted according to production needs to adapt to gripping tasks of different specifications and quantities of bottles and cans. This design enhances the versatility and flexibility of the bottle gripping mechanism.

[0043] For example, see Figures 3-4 As shown, there are two sets of gripper gripping components 400, and the two sets of gripper gripping components 400 are symmetrically arranged about the central axis of the mounting plate 3 103.

[0044] In this technical solution, two sets of gripper components 400 are symmetrically arranged on both sides of the central axis of the mounting plate 3103. This layout ensures that the entire bottle and can gripping mechanism remains balanced when gripping bottles and cans, preventing tilting or wobbling due to excessive force on one side, thus improving the stability and reliability of the gripping. In actual operation, the two sets of gripper components 400 can grip two bottles and cans simultaneously, greatly improving production efficiency. Moreover, since the two sets of gripper components have identical structures and functions, they can be interchanged during maintenance and repair, reducing maintenance costs and difficulty. Simultaneously, this symmetrical design also makes the overall bottle and can gripping mechanism more neat and aesthetically pleasing, meeting the design requirements of modern production equipment.

[0045] Working Principle: When this bottle and can gripping mechanism is in use, the bottle cap positioning component 200 first precisely positions the bottle cap. Then, the capping cylinder 203 on the capping cylinder mounting platform 202 starts working, its piston rod extending and retracting to drive the positioning sleeve mounting plate 204 to move up and down along the limiting post 205, thereby lowering the bottle cap positioning sleeve 201 to the appropriate position. The positioning cavity inside the bottle cap positioning sleeve 201, thanks to its design that matches the shape of the bottle cap and the effect of the elastic buffer layer, accurately and stably positions the bottle cap within it. Simultaneously, the gripper lifting component 300 comes into play. The lifting cylinders 301 fixed at the four corners of the bottom of the mounting plate 2 102 are activated, their piston rods driving the mounting plate 3 103 to rise and fall, thereby adjusting the height of the gripper gripping component 400 to reach a suitable position for gripping the bottle and can. When it reaches the appropriate position... After reaching the desired height, the gripper assembly 400 begins to operate. Upon receiving instructions from the control system, the gripper cylinder 401 drives the gripper 402 to open and close via the extension and retraction of the piston rod. The two gripper assemblies 400 are symmetrically arranged about the central axis of the mounting plate 3 103, allowing for simultaneous gripping of two bottles / cans and ensuring a balanced and stable gripping process. During gripping, the slide bar protective sleeve 107 outside the slide bar 104 provides protection for the slide bar 104. The solenoid valve 108 precisely controls the operation of each cylinder, ensuring the entire mechanism operates stably according to a predetermined program. The electronic connector 109 transmits electrical signals and connects to the external control system, accurately transmitting instructions to each actuator. Ultimately, this achieves efficient, stable, and damage-free gripping of bottles / cans, meeting the needs of automated production lines in the food, beverage, chemical, and pharmaceutical industries.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
