Description

Technical Field

[0001] This application relates to the technical field of automated equipment, and in particular to a valve cutting device. Background Technology

[0002] In the production process of aerosol valves, the cutting of valve guide tubes mainly relies on manual operation. Operators typically use hand tools or simple jigs to position, measure, and cut the valves to shorten long valves to meet assembly requirements.

[0003] This method can meet the production needs of small batches and multiple varieties to a certain extent, but the overall process is cumbersome, the efficiency is limited, and it is highly dependent on the experience and proficiency of the operators. It cannot achieve continuous and batch operations, and has become the main bottleneck restricting the improvement of production efficiency and capacity. Summary of the Invention

The track is adapted to the shape of the main body of the valve so that the main body of the valve can enter the track.

[0009] In one embodiment, the inner wall of the hopper is provided with an adsorption section, which is arranged circumferentially along the turntable and is used to adsorb the main body part.

[0010] In one embodiment, the hopper is arranged at an angle, with one end of the track located at the top of the bottom surface of the hopper and arranged along the side wall of the hopper, so that the valve can output under the action of gravity.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0040] As a key component for controlling the release of contents, aerosol valves often involve a cutting process during their manufacturing. Specifically, valves manufactured to uniform specifications typically have a relatively long conduit, but this conduit needs to be cut to a specific length according to the design requirements of the final product (such as aerosol cans of different capacities, cartridge gas canisters, etc.).

[0041] Currently, this process mainly relies on manual measurement and cutting using tools. This method suffers from low efficiency and inconsistent results, with cutting lengths varying from person to person, potentially affecting subsequent assembly. Furthermore, repetitive manual work also carries certain safety risks and high labor costs.

[0042] To address the aforementioned issues, this application provides a valve cutting device designed to automate the entire process from feeding messy valves to precise cutting of conduits, and automatic separation of finished products from waste, thereby improving cutting efficiency, ensuring cutting accuracy, and reducing reliance on manual labor.

[0043] The following is in conjunction with the appendix Figure 1-10 The embodiments of this application will be described in further detail.

[0044] See Figure 1 , Figure 1 A three-dimensional structural schematic diagram of the valve cutting device in one embodiment of this application is shown. Figure 2 A three-dimensional structural schematic diagram of a valve in one embodiment of this application is shown.

[0045] One embodiment of this application provides a valve cutting device, including a frame 1 as an integral support structure. The frame 1 has a dedicated area for performing the cutting operation of the conduit 52 of the valve 5, namely the cutting station 11. Along the transmission direction of the valve 5 from feeding to completion of cutting, the valve cutting device also includes a feeding assembly 2, a straightening assembly 3, a shearing assembly 4, and an electrical control system (not shown) that coordinates and controls the operation of the entire device, arranged sequentially on the frame 1.

[0046] Combination Figure 3 and Figure 4 As shown, Figure 3 This diagram illustrates a feeding assembly in a non-operating state according to one embodiment of the present application. Figure 4 The diagram illustrates a feeding assembly in a working state according to an embodiment of this application. The working state refers to the operational state after sequential startup under the control of the electronic control system, while the non-working state refers to the state where operation has ceased under the control of the electronic control system.

[0047] Specifically, the feeding assembly 2, as the starting point of the automated process, is used to organize the randomly piled valves 5, arranging them in an orderly manner and adjusting them to a predetermined posture suitable for transmission and subsequent processing. The valves 5 are then transported one by one or continuously to the cutting station 11. The feeding assembly 2 includes a sorting unit 21 and a track 22. The sorting unit 21 is the mechanism for initial posture selection and orderly output.

[0048] In some embodiments, the sorting unit 21 is specifically a vibration sorting mechanism. The sorting unit 21 has a conveying channel and a screening structure inside. Vibration causes the valve 5 to gradually adjust its direction during movement, ultimately ensuring that only valves 5 in the correct posture are output. In this embodiment, the correct posture refers to... Figure 2 The valve 5 shown is positioned with its main body 51 on the right and the conduit 52 on the left.

[0049] In some other embodiments, the sorting unit 21 may also be a gravity feeder with a mechanical screening track or a rotary drum sorter, which can also sort and orient the valve 5 through gravity, centrifugal force and specific mechanical structures.

[0050] See Figure 1As shown in the embodiment of this application, the sorting unit 21 includes a hopper 211 and a turntable 212 rotatably installed in the hopper 211. A gap is formed between the inner wall of the hopper 211 and the periphery of the turntable 212, and this gap constitutes a groove 7 for the main body 51 of the valve 5 to be accommodated.

[0051] During the operation of the sorting unit 21, since the main body 51 of the valve 5 is heavier than its conduit 52, the main body 51 will be thrown out of the turntable 212 and fit into the groove 7 as the turntable 212 rotates. Then, as the turntable 212 continues to rotate, it will enter the track 22 in sequence, thereby completing the sorting and posture adjustment of the valve 5.

[0052] Furthermore, in some embodiments, the inner wall of the hopper 211 is formed with an adsorption section 2111 for adsorbing the main body portion 51. Specifically, the adsorption section 2111 is made of magnetic material and is arranged circumferentially along the turntable 212 to apply an adsorption force to the main body portion 51 when it is thrown out, so that the main body portion 51 can smoothly enter the groove 7.

[0053] In some other embodiments, the sorting unit 21 further includes at least one agitator 213 disposed within the hopper 211, with all agitators 213 spaced apart and arranged perpendicular to the bottom surface of the hopper 211. During the rotation of the turntable 212, the agitators 213 can agitate the intertwined and stacked valves 5, thereby facilitating the sorting, arrangement, and orientation adjustment of the valves 5.

[0054] The valve 5 output from the sorting unit 21 then enters the track 22. In this embodiment, the hopper 211 is inclined relative to the frame 1, and the track 22 is a transmission channel connecting the outlet of the groove 7 and the cutting station 11. The entrance end of the track 22 is located at the top of the bottom surface of the hopper 211 and is arranged along the side wall of the hopper 211. Specifically, the cross-sectional shape of the track 22 is constructed to match the contour of the valve 5, to guide and constrain the valve 5 to slide smoothly along a predetermined path to the cutting station 11. It can be understood that, depending on the actual transmission requirements, the track 22 can have a certain inclination angle to assist in the conveying with gravity; it can also be combined with a drive mechanism such as a vibrator or belt to achieve a more controllable conveying speed.

[0055] See Figure 1 , Figure 5 and Figure 6 As shown, Figure 5 This diagram illustrates the straightening component in its working state according to one embodiment of the present application. Figure 6A schematic diagram of the clamping member and the straightening drive member in one embodiment of this application is shown. After the valve 5 is conveyed by the feeding assembly 2 and positioned at the cutting station 11, the straightening assembly 3 is activated and straightens the conduit 52 of the valve 5, which may be in a bent state, to ensure the accuracy of the subsequent cutting length.

[0056] Specifically, the straightening assembly 3 includes a clamping member 31 and a straightening drive member 32. The clamping member 31 is the part that directly acts on the conduit 52, and its structural design needs to adapt to the shape and size of the conduit 52. The clamping member 31 can be one or more pairs of pneumatically or electrically driven jaws. In this embodiment, the illustration only shows an example of the clamping member 31 including a pair of jaws.

[0057] In some other embodiments, the gripping surface of the gripper (not shown) may be designed as an arcuate surface that matches the outer diameter of the catheter 52 to provide a stable and uniform gripping force and avoid damage to the catheter 52.

[0058] The straightening drive 32 serves as a power source, driving the clamping member 31 to the frame 1. Specifically, the straightening drive 32 can be any one or a combination of several linear motion mechanisms, such as a linear cylinder, an electric push rod, or a servo cylinder. When the electronic control system issues a command, the straightening drive 32 starts, driving the clamping member 31 to move along the axial direction of the guide tube 52, i.e., the direction in which it needs to be straightened. During the movement, the clamping member 31 applies an axial traction force to the guide tube 52 through the friction or clamping force between the clamping member 31 and the guide tube 52, thereby gradually stretching the bent guide tube 52 to a straight state.

[0059] Combination Figure 5 and Figure 7 As shown, Figure 7 A schematic diagram of the support member and support drive member in one embodiment of this application is shown. To further optimize the straightening effect and ensure that the conduit 52 is sufficiently taut and does not slip near the cutting point, the straightening assembly 3 may further include a support member 33 and a support drive member 34. Along the axial direction of the conduit 52, the support member 33 is arranged opposite to the clamping member 31, that is, the support member 33 is located at the other end of the section of the conduit 52 that needs to be straightened, so as to straighten the conduit 52.

[0060] In this embodiment, the support member 33 provides a support point to hold and support the end of the conduit 52 away from the clamping member 31. The support drive member 34 drives the support member 33 to the frame 1 and can drive the support member 33 into or out of the cutting station 11 to avoid interference between the support member 33 and the transmission path of the valve 5.

[0061] When the valve cutting device is in operation, the support drive 34 first moves the support 33 to the cutting station 11, bringing it into contact with the end of the guide tube 52 and providing support. Then, the clamping member 31 moves away from the support 33 under the drive of the straightening drive 32. At this time, the guide tube 52 is constrained between the clamping member 31 and the support 33 and subjected to axial tensile force, and is straightened on the cutting station 11. This two-point tension method ensures that the guide tube 52 remains straight at the cutting station, thereby improving the subsequent cutting accuracy.

[0062] See Figure 1 , Figure 5 and Figure 8 As shown, Figure 8 A schematic diagram of the shearing assembly in operation is shown in one embodiment of this application. After the guide tube 52 is straightened and fixed, the shearing assembly 4 performs a cutting action. The shearing assembly 4 includes a cutting drive 41 and a cutting element 42. The cutting element 42 is a tool that directly performs the cutting, usually a pair of scissor blades, one of which is a moving blade and the other is a fixed blade; in some other embodiments, the cutting element 42 may also be a single-edged blade that cooperates with an anvil. The cutting drive 41, as a power source, is mounted on the frame 1 and is connected to the moving blade of the cutting element 42 via a linkage, slider, or other mechanism to achieve control over the opening and closing of the cutting element 42.

[0063] In this embodiment, the cutting drive 41 can be any one of a cylinder, a hydraulic cylinder, or a linear motor. Upon receiving a cutting signal, the cutting drive 41 moves rapidly, driving the moving blade of the cutting piece 42 to rotate and engage with the fixed blade or anvil to complete the cutting of the guide tube 52. Then, it resets and opens to prepare for the next work cycle.

[0064] In some other embodiments, to accurately trigger the cutting action, the shearing assembly 4 may also include a position sensor (not shown). The position sensor is located at the cutting station 11 and electrically connected to the aforementioned electronic control system. The shearing assembly 4 is used to detect in real time whether the predetermined cutting point on the valve 5, particularly the conduit 52, has reached the precise cutting position, so as to trigger the cutting action in a timely manner.

[0065] In this embodiment, the position sensor can be any one of a photoelectric sensor, fiber optic sensor, or vision sensor, as long as it can accurately locate the cutting position. This application does not impose any restrictions on this. During actual operation, when the position sensor detects that valve 5 is accurately positioned, it sends a trigger signal to the electronic control system. The electronic control system then instructs the cutting drive component 41 to operate, thereby effectively avoiding cutting length errors caused by feeding position deviations.

[0066] See Figure 8 and Figure 9 As shown, Figure 9 A schematic diagram of the shearing assembly in one embodiment of this application is shown. In some embodiments, to meet the diverse needs of valves 5 for different applications in cutting the length of conduits 52, the shearing assembly 4 further includes an adjusting drive 43 and a mounting base 44. In this configuration, the cutting drive 41 is not directly fixed to the frame 1, but is mounted on a movable mounting base 44.

[0067] The adjustment drive 43 is located on the frame 1 and is connected to the mounting base 44. It can drive the mounting base 44 and the cutting drive 41 and the cutting piece 42 located on the mounting base 44 to move as a whole along the axial direction and / or radial direction of the guide tube 52, thereby realizing the position adjustment of the cutting piece 42 in the horizontal direction.

[0068] Specifically, the adjustment drive component 43 includes a first adjustment part 431 and a second adjustment part 432. The first adjustment part 431 is mounted on the frame 1, the second adjustment part 432 is driven by the first adjustment part 431, and the mounting base 44 is driven by the second adjustment part 432. Driven by the first adjustment part 431, the mounting base 44 can move axially along the guide tube 52 to adjust the preset cutting length of the cutting piece 42. Driven by the second adjustment part 432, the mounting base 44 can move radially along the guide tube 52, specifically entering or exiting the cutting station 11 under the drive of the second adjustment part 432. This ensures that the cutting piece 42 can promptly enter the cutting station 11 when cutting the guide tube 52 is required and promptly exit the cutting station 11 after cutting, avoiding interference with the transmission of the valve 5 after cutting.

[0069] In this embodiment, the first adjustment unit 431 can be a manually adjustable screw and nut mechanism, or an automated mechanism such as a ball screw slide driven by a servo motor. The second adjustment unit 432 can have the same structure as the first adjustment unit 431, or it can directly use a cylinder as the driving component to achieve linear drive.

[0070] See Figure 1 and Figure 10 As shown, Figure 10 The diagram shows a valve cutting device after cutting, according to an example of this application. After cutting, the cut valve body (i.e., the finished valve) and the excess guide pipe section (i.e., the waste guide pipe) usually fall together. In some embodiments, to achieve automated collection and sorting, the valve cutting device further includes a separation component located downstream of the cutting assembly 4. The separation component is used to automatically separate and collect the finished valve and the waste guide pipe separately.

[0071] Specifically, the separation component includes a sieve disc 6. The sieve disc 6 is configured to be inclined, and a plurality of sieve holes 61 are formed on the sieve disc 6. In the embodiments of this application, the size of the sieve holes 61 is specially designed, and its aperture is configured to be larger than the cross-sectional size of the conduit waste but smaller than the minimum cross-sectional size of the valve finished product body. When the mixture of valve finished product and conduit waste falls onto the sieve disc 6, under the action of gravity, the smaller conduit waste can pass through the sieve holes 61 and fall down, while the larger valve finished product is blocked by the sieve holes 61 and slides to one side along the inclined surface of the sieve disc 6.

[0072] In some other embodiments, to facilitate collection, the separation assembly also includes a waste collection hopper (not shown) and a finished product collection box (not shown). The waste collection hopper is located directly below the screen plate 6 to collect the waste material falling through the screen holes 61, facilitating centralized processing. The finished product collection box is located at the outlet end of the lower side of the screen plate 6, aligned with the sliding direction of the screen plate 6. Because the screen plate 6 is inclined, the blocked valve finished product automatically slides into the finished product collection box under gravity, thus achieving unpowered, continuous finished product collection. The entire separation process requires no manual intervention, making it highly efficient and reliable.

[0073] See Figure 1 As shown, the electrical control system is the core of the entire valve cutting device. In some embodiments, the electrical control system includes a PLC controller, an electrical cabinet, a solenoid valve assembly, a time relay, a counter, and interface circuits for various sensors and drivers. The electrical control system is electrically connected to the vibration controller or drive motor of the feeding assembly 2, the straightening drive 32 and support drive 34 of the straightening assembly 3, the cutting drive 41 and adjustment drive 43 of the shearing assembly 4, and the position sensor.

[0074] The electrical control system coordinates the orderly operation of each component according to the preset program logic: it controls the feeding component 2 to continuously supply material; after the valve 5 reaches the cutting station 11, it controls the straightening component 3 to straighten the guide tube 52; after receiving the position sensor signal, it controls the shearing component 4 to perform cutting; at the same time, the production quantity can be recorded by the counter. The entire work cycle is carried out automatically and continuously until the task is completed.

[0075] In actual operation of the valve cutting device described above, the operator pours a large batch of messy aerosol valves 5 into the hopper of the vibration sorting unit 21 of the feeding assembly 2. The sorting unit 21 is activated, and through vibration, it sorts and arranges the valves 5 and adjusts them so that the guide tubes 52 face upwards, and outputs them sequentially to the connecting rail 22. The valves 5 on the rail 22 slide smoothly to the cutting station 11 under gravity or auxiliary drive.

[0076] Upon reaching the cutting station 11, the support drive 34 of the straightening assembly 3 pushes the support 33 to hold and clamp the free end of the conduit 52. Subsequently, the straightening drive 32 drives the clamping member 31 to move, straightening the conduit 52 between the support 33 and the clamping member 31. Simultaneously, the position sensor of the shearing assembly 4 confirms the accurate position of the valve 5 cutting point. The electrical control system issues a command, and the cutting drive 41 of the shearing assembly 4 quickly moves, driving the cutting member 42 to cut the conduit 52.

[0077] The cut valve and conduit waste fall together into the screen plate 6 below. The conduit waste falls through the screen holes 61 into the waste collection hopper, while the valve slides down the inclined surface of the screen plate 6 into the finished product collection box. The counter in the electrical control system records the completion of one cycle. The support 33 and clamping 31 reset, and the next valve 5 on the track 22 enters the cutting station 11 to start the next cycle. By adjusting the adjusting drive 43 of the shearing assembly 4, the position of the cut piece 42 can be easily changed, thereby adjusting the cutting length of the conduit 52 to meet the production needs of different specifications of products.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
