Description

Technical Field

[0001] The invention belongs to the technical field of wind chime processing equipment, and in particular relates to a wind chime pipe assembly machine. Background Art

[0002] Wind chimes are objects that can make sounds when the wind blows, and are mostly used as ornaments. They can make sounds through the collision of various bells or other objects when the wind blows. There are many types of wind chimes, such as Japanese wind chimes, octagonal wind chimes, etc. Wind chimes have both visual beauty and pleasant auditory enjoyment.

[0003] Wind chimes are generally composed of several wind chime tubes suspended on connectors by ropes. At present, the wind chime tubes on the market are usually drilled with holes to insert the pins for tying the ropes, or directly install plastic air eyes at the holes, and connect the ropes to the plastic air eyes. However, drilling holes will leave marks on the outer wall of the wind chime tube, destroying the overall appearance of the outer wall of the wind chime tube and affecting the aesthetics. After drilling the holes, the edges of the holes need to be polished, which is time-consuming and labor-intensive. In the bolt-type wind chime, the rope will be displaced on the bolt, which will affect the tone of the wind chime, and the bolt is easy to fall off during the shaking of the wind chime, posing a safety hazard.

[0004] To solve the above problems, a device for making a new type of wind chime tube has appeared on the market. The patent number of the device is CN202210432516.8, and the name is a Chinese invention patent of an assembly machine for installing a retaining spring in a wind chime tube. It discloses an assembly machine for installing a retaining spring in a wind chime tube, which includes a frame and a loading mechanism, a conveying mechanism, an inner groove digging mechanism, a spring loading mechanism and a discharging mechanism installed on the frame. The conveying mechanism is used to transport the wind chime tube from the loading structure to the discharging mechanism. The inner groove digging mechanism and the spring loading mechanism are sequentially arranged on the conveying stroke of the wind chime tube. The inner groove digging mechanism includes a groove cutter control pushing device, a groove positioning device and a three-jaw chuck. The spring loading device includes a vibration disk, a retaining spring tube assembly, a retaining spring grabbing and pushing device, a flipping auxiliary device and a driving device. However, in the above scheme, it is necessary to first groove the inner wall of the wind chime tube through the inner groove digging mechanism, and then push the retaining ring into the hook groove. This method is not only cumbersome and inefficient, but also requires more components and has a relatively high failure rate. Therefore, a wind chime tube assembly machine with simple procedures, high work efficiency and low failure rate is needed. Summary of the invention

The adjusting frame is slidably connected through the cooperation of the guide rail and the slider.

[0038] Through the above technical solution, compared with the prior art, the present invention has the following beneficial effects: A wind chime tube assembling machine is composed of a tube body feeding mechanism, a conveying mechanism, a buckle feeding mechanism, a pressing-in mechanism and a discharging mechanism. The tube body feeding mechanism is installed at the initial end of the machine frame, and includes a feeding rack for storing the wind chime tube bodies, a lifting device for sequentially pushing out the wind chime tubes in the feeding rack, a material distributing device for receiving the wind chime tubes at the lifting device and conveying them to the lower part of the tube body gripping device, and a tube body gripping device for gripping and placing the wind chime tubes separated by the material distributing device on the conveying mechanism. The conveying mechanism includes two groups of oppositely arranged sprocket assemblies, which are driven by a sprocket driving motor. There are tube seats on the chains of the sprocket assemblies, and the tube seats on the two chains correspond to each other. After the tube body gripping device grabs the wind chime tube body from the material distributing device and places it on the tube seat, the wind chime tube body located on the tube seat will move to between the buckle feeding mechanism and the pressing-in mechanism along with the transmission direction of the chain. The buckle feeding mechanism includes a vibrating plate, a buckle pushing module and a buckle gripping device. The vibrating plate is used for storing and conveying the buckles. The buckle gripping device is used for clamping and placing the buckles in the output groove of the vibrating plate at the pushing end of the buckle pushing module. The buckle pushing module pushes the buckles in front of its pushing end into the tube body of the wind chime tube. The pressing-in mechanism plays a role in limiting and abutting against the buckles.

[0039] Among them, the ejector rod in the pressing-in mechanism and the push rod in the buckle pushing module are oppositely arranged. When the tube seat with the wind chime tube body moves to between the buckle pushing module and the pressing-in mechanism, the ejecting module in the pressing-in mechanism will be started. The ejector rod on the ejecting module moves forward and extends into the tube body. After the ejector rod is in place, the buckle gripping device grabs the buckles at the output groove of the vibrating plate and places them on the buckle fixture.

[0040] When the sensor at the buckle fixture senses the buckle, the buckle pushing module is activated. The push rod in the buckle pushing module drives the buckle to move forward and enter the tube body. The buckle that has just entered the tube body does not contact the inner wall of the tube body. When the push rod pushes the buckle until it abuts against the ejector rod, it will continue to exert pressure on the buckle. At this time, the two sides of the buckle that were originally bent will expand outwards until they abut against the inner wall of the tube body to form a clamped state, realizing the fixed installation of the tube body and the buckle. After the buckle is installed in place, the ejector rod and the push rod withdraw from the tube body in sequence. Then, the sprocket assembly drives the assembled wind chime tube to continue moving to the discharging mechanism. The blanking and grasping cylinder in the discharging mechanism grabs the wind chime tube on the tube seat and puts it into the bin to complete the entire composition process of the wind chime tube.

[0041] The above technical solution assembles the buckle into the wind chime tube in a fully automatic manner, saving the existing multiple assembly processes to one process. At the same time, there is no need to use an inner groove digging mechanism and a spring loading mechanism, streamlining the entire installation process, reducing the overall failure rate, thereby increasing the production efficiency of the equipment. Moreover, the produced wind chime tube has higher firmness, solving the technical problems of the existing wind chime tube assembly equipment, such as cumbersome processes, low work efficiency, a large number of required components, and high failure rates.

[0061] As Figures 1-12 shown: A wind chime tube assembly machine includes a frame 1, on which a tube body feeding mechanism, a conveying mechanism, a buckle feeding mechanism, a pressing-in mechanism, and a discharging mechanism are installed. In this embodiment, an outer frame 100 is provided on the frame 1, and the outer frame 100 has a feeding port and a discharging port. The tube body feeding mechanism and the discharging mechanism are respectively arranged corresponding to the feeding port and the discharging port. A main control device 110 is provided on the outer frame 100, and the main control device 110 has a touch panel for human-machine interaction. The main control device 110 controls the tube body feeding mechanism, the conveying mechanism, the buckle feeding mechanism, the pressing-in mechanism, and the discharging mechanism through a PLC to realize the fully automated conveying of wind chime tubes and the positioning and installation of buckles, with a very high degree of automation.

[0062] The tube body feeding mechanism is installed at the initial end of the frame and is used for storing and feeding the wind chime tubes.

[0063] The conveying mechanism is used to receive the wind chime tubes output from the tube body feeding mechanism and convey the wind chime tubes to the discharging mechanism. During the conveying process of the wind chime tubes, they will pass between the buckle feeding mechanism and the pressing-in mechanism.

[0064] The buckle feeding mechanism includes:

[0065] A vibrating disk 2, which is used for storing and outputting buckles;

[0066] A buckle pushing device 3, which is used to push the buckle into and snap it into the wind chime tube;

[0067] A buckle grasping device 4, which is used to grasp the buckle from the discharging groove of the vibrating disk 2 and place it at the pushing end of the buckle pushing device 3;

[0068] The pressing mechanism and the buckle pushing device 3 are arranged opposite to each other. The pressing mechanism extends from the pipe orifice of the wind chime tube far away from the buckle pushing device 3 for abutting and limiting the buckle.

[0069] The discharging mechanism is used to output the wind chime tube with the assembled buckle.

[0070] As Figures 1-5 shown in the figure: The pipe body feeding mechanism includes a feeding rack 5, a lifting device 6, a material distributing device 7 and a pipe body grasping device 8;

[0071] The feeding rack 5 is used to store the pipe body of the wind chime tube; in this embodiment, the feeding rack 5 is installed on one side of the feeding port, and a support rack for supporting the feeding rack 5 is arranged below the feeding rack 5.

[0072] As Figure 6 shown in the figure: The lifting device 6 includes a mounting frame 601, a plurality of movable ejector rods 602 that are longitudinally offset and arranged side by side in the transverse direction and installed on the mounting frame 601, a lifting cylinder 603 for driving all the movable ejector rods 602 to move up and down synchronously, and an obliquely arranged guide plate 604 for the wind chime tube to slide down;

[0073] In this embodiment, the mounting frame 601 includes a fixed plate 605. The lifting cylinder 603 is installed at the lower end of the fixed plate 605. The upper end of the fixed plate 605 is connected with a connecting plate 606. A plurality of movable top plates 607 are fixedly arranged at the upper end of the connecting plate 606. A plurality of movable ejector rods 602 are all installed above the movable top plates 607. A partition plate 608 is arranged between the movable ejector rods 602. The upper end surfaces of the partition plate 608 and the movable ejector rods 602 are both inclined and smoothly transition with each other. The partition plate 608 is fixedly installed on the mounting frame 601.

[0074] The lifting cylinder 603 is fixed through the fixed plate 605 and is used to drive the connecting plate 606 to move up and down. When the connecting plate 606 moves upward, it will drive the movable top plate 607 to move upward, and then drive the movable ejector rod 602 to move upward. Since the upper end surfaces of the partition plate 608 and the movable ejector rod 602 are both inclined, the wind chime tube entering the upper end surface of the partition plate 608 will roll to the upper end surface of the movable ejector rod 602. The partition plate 608 is used for limiting. And when the movable ejector rod 602 moves upward to abut against the upper end surface of the next partition plate 608, the wind chime tube will continue to move and roll to the upper end surface of the next partition plate 608, and so on. Finally, the wind chime tube will be gradually conveyed close to the material distributing device 7.

[0075] The material distributing device 7 includes a material distributing plate 701 for conveying the wind chime tube below the pipe body grasping device 8 and a top material module for pushing the wind chime tube upward;

[0076] As Figure 7As shown in the figure: In this embodiment, the ejector module includes an ejector block 702 and an ejector cylinder 703. At the upper end of the material distribution plate 701, there are a first material distribution card slot 704 and a second material distribution card slot 705. After being guided by the guide plate 604, the wind chime tube will first be clamped in the first material distribution card slot 704. The ejector cylinder 703 drives the ejector block 702 to move upward, thereby pushing up the wind chime tube. At this time, the wind chime tube will cross the first material distribution card slot 704 and enter the second material distribution card slot 705. When the wind chime tube enters the second material distribution card slot 705, the tube body grasping device 8 will pick up the wind chime tube here. And the ejector module is fixedly installed on both sides in the conveying direction of the wind chime tube through the mounting seat. In this embodiment, a first sensor for triggering the ejector cylinder 703 is provided between the two first material distribution card slots 704, and a second sensor for triggering the tube body grasping device 8 is provided between the second material distribution card slots 705.

[0077] As Figure 7 shown: The tube body grasping device 8 includes a manipulator module 801 and a linear drive module 802 for driving the activity of the manipulator module 801. The driving manipulator module 801 is used to grasp and move the wind chime tube located on the material distribution plate 701 to the conveying mechanism. In this embodiment, the linear drive module 802 includes a guide rail mounting plate 803 and a first tube body grasping drive cylinder 804. A guide rail is provided on the guide rail mounting plate 803, and a slider is movably provided on the guide rail. A drive plate is installed on the slider. The first tube body grasping drive cylinder 804 is used to drive the drive plate to move on the guide rail.

[0078] The manipulator module 801 includes a support frame 805. The support frame 805 is installed on the drive plate. Above the support frame 805, a second tube body grasping drive cylinder 806 is installed. At least one third tube body grasping drive cylinder 807 is installed in the support frame 805. A clamping jaw 808 is provided at the lower end of the third tube body grasping drive cylinder 807. The third tube body grasping drive cylinder 807 is used to drive the clamping jaw 808 to work. The second tube body grasping drive cylinder 806 is used to drive the support frame 805 to move up and down, and finally convey the wind chime tube clamped by the clamping jaw 808 to the conveying mechanism.

[0079] It should be noted that the above-mentioned material distribution plate 701, guide rail mounting plate 803 and their corresponding structures are all symmetrically installed front and back to ensure that the wind chime tube can be displaced and conveyed smoothly.

[0080] Here, a feeding sensor is generally provided between the tube body grasping device 8 and the conveying mechanism. When the feeding sensor does not detect that a wind chime tube is placed on the conveying mechanism, it will automatically alarm. Generally, there is a problem in one of the processes of the tube body feeding mechanism, and the machine failure can be checked in time.

[0081] As Figures 3-5As shown in the figure: The conveying mechanism includes at least two sprocket assemblies 9 arranged along the conveying direction of the wind chime tube and running synchronously, a sprocket drive motor 901 for driving the sprocket assemblies 9 to work, and tube seats 902 evenly spaced and installed on the chains of the sprocket assemblies 9. The tube seats 902 on different sprocket assemblies 9 are respectively in one-to-one position correspondence along the axial direction of the wind chime tube, and are jointly used to support and place the wind chime tube.

[0082] Generally, the sprocket assembly 9 includes a driving sprocket and multiple driven sprockets. Among them, the driving sprocket is connected to the sprocket drive motor 901, and the driving sprocket and the driven sprockets are connected by a transmission rod. Generally, there are two groups of chains, which are symmetrically arranged front and back. All sprockets on the chains except the above-mentioned driving sprocket are driven sprockets. When one of the driving sprockets is driven to rotate by the sprocket drive motor 901, through the transmission of the transmission rod, it will drive the rotation of its corresponding driven sprocket 4, and the driven sprockets on the same chain as the driving sprocket will also rotate, and then drive the rotation of both chains. Moreover, the rotation of the two chains is synchronous. Furthermore, the tube seats 902 installed on the two chains will also be driven synchronously to ensure the stable and directional conveyance of the wind chime tube.

[0083] As Figures 9-10 shown in the figure: The buckle pushing device 3 includes a pedestal 301 arranged on one side of the sprocket assembly 9 and a buckle pushing module 302 installed on the pedestal 301. A push rod seat 303 is provided at the pushing end of the buckle pushing module 302, and a push rod 304 corresponding to the tube seat 902 is provided on the push rod seat 303. A buckle placement rack 305 is also provided on the pedestal 301. The buckle placement rack 305 is located at the front end of the buckle pushing module 302. A buckle fixture 306 is provided on the buckle placement rack 305, and a guide groove 307 is opened on the buckle fixture 306. The guide groove 307 is correspondingly arranged with the push rod 304, and the guide groove 307 is used for the placement of the buckle and the pushing of the push rod 304.

[0084] In this embodiment, the buckle pushing module 302 includes a mold frame. A pushing end is movably provided on the mold frame. A servo motor for driving the pushing end to move horizontally along the mold frame is provided on one side of the mold frame, and a sensor is provided at the guide groove 307.

[0103] In addition, the buckle in the present invention includes a suspension portion and abutting portions located on both sides of the suspension portion. The abutting portions have a number of upwardly bent abutting claws, and the abutting claws contact and fit with the inner wall of the tube to limit the buckle in the tube. When the buckle is in the initial state, its abutting portions are folded together. When the push rod 304 pushes the buckle into the tube, at first the buckle is still in an unfolded state, and the abutting portions on both sides do not contact the inner wall of the tube. When the suspension portion at the rear of the buckle abuts against the top rod 13, the push rod 304 still continues to apply pressure, so as to force the folded abutting portions to extend to both sides until the abutting claws provided on the abutting portions abut against the inner wall of the tube, thereby realizing the fixed installation of the buckle.

[0104] The beneficial effects of the present invention are as follows:

[0105] A wind chime tube assembly machine is composed of a tube body feeding mechanism, a conveying mechanism, a buckle feeding mechanism, a pressing-in mechanism and a discharging mechanism. The tube body feeding mechanism is installed at the initial end of the frame 1, and includes a feeding rack 5 for storing the tube bodies of the wind chime tubes, a lifting device 6 for sequentially ejecting the wind chime tubes in the feeding rack 5, a material distributing device 7 for picking up the wind chime tubes at the lifting device 6 and conveying them to the lower part of the tube body grasping device 8, and a tube body grasping device 8 for grasping the wind chime tubes separated by the material distributing device 7 and placing them on the conveying mechanism. The conveying mechanism includes two sets of oppositely arranged sprocket assemblies 9, and the sprocket assemblies 9 are driven by a sprocket driving motor 901. Tube seats 902 are provided on the chains of the sprocket assemblies 9, and the tube seats 902 on the two sets of chains correspond to each other. After the tube body grasping device 8 grasps the wind chime tube body from the material distributing device 7 and places it on the tube seat 902, the wind chime tube body located on the tube seat 902 will move along with the transmission direction of the chain to between the buckle feeding mechanism and the pressing-in mechanism. The buckle feeding mechanism includes a vibrating disk 2, a buckle pushing module 3 and a buckle grasping device 4. The vibrating disk 2 is used for storing and conveying the buckles. The buckle grasping device 4 is used for clamping the buckles in the output groove of the vibrating disk 2 and placing them at the pushing end of the buckle pushing module 3. The buckle pushing module 3 pushes the buckles in front of its pushing end into the tube body of the wind chime tube. The pressing-in mechanism plays a role in limiting and abutting against the buckles.

[0106] Among them, the ejector rod 13 in the pressing-in mechanism and the push rod 304 in the buckle pushing module 3 are oppositely arranged. When the tube seat 902 with the wind chime tube body moves to between the buckle pushing module 3 and the pressing-in mechanism, the ejecting module 10 in the pressing-in mechanism will be started. The ejector rod 13 on the ejecting module 10 moves forward and extends into the tube body. After the ejector rod 13 is in place, the buckle grasping device 8 grasps the buckles at the output groove of the vibrating disk 2 and places them on the buckle fixture 306.

[0107] When the sensor at the buckle fixture 306 senses the buckle, the buckle pushing module 3 is started. The push rod 304 in the buckle pushing module 3 drives the buckle to move forward and enter the tube body. The buckle just entering the tube body does not contact the inner wall of the tube body. When the push rod 304 pushes the buckle to abut against the ejector rod 13, pressure will continue to be applied to the buckle. At this time, the two sides of the buckle that were originally in a bent state will expand outwards until they abut against the inner wall of the tube body to form a clamping state, realizing the fixed installation of the tube body and the buckle. When the buckle is installed in place, the ejector rod 10 and the push rod 304 withdraw from the tube body in sequence. Then, the sprocket assembly 9 drives the assembled wind chime tube to continue moving to the discharging mechanism. The blanking grasping cylinder 3006 in the discharging mechanism grasps the wind chime tube on the tube seat 902 and puts it into the bin to complete the entire composition process of the wind chime tube.

[0108] The above technical solution assembles the buckle into the wind chime tube in a fully automatic manner, saving the existing multiple assembly processes to one process. At the same time, there is no need to use an inner groove digging mechanism and a spring loading mechanism, streamlining the entire installation process and reducing the overall failure rate, thereby increasing the production efficiency of the equipment. Moreover, the produced wind chime tube has higher firmness, solving the technical problems of the existing wind chime tube assembly equipment, such as cumbersome processes, low work efficiency, more components required, and high failure rate.

[0109] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
