Description

Material transport and assembly system Technical Field

[0001] This invention relates to the field of compression molding technology, and more specifically to a material transport and assembly system. Background Technology

[0002] In the field of compression molding technology, common material conveying and assembly systems include a material conveying device and a material assembly device that are disc-shaped when viewed from above. As shown in Figure 1, the material conveying device 100 is provided with multiple sets of material conveying mechanisms 101 spaced apart along the circumference, and the material assembly device 200 is provided with multiple sets of molding molds spaced apart along the circumference. After the material conveying mechanism picks up the material, it sends the material to the mold cavity or insert of each molding mold for assembly processing.

[0003] Ideally, the material picked up by the material conveying mechanism should be placed concentrically into the mold cavity of the forming mold or the assembly point of the insert. However, due to the very narrow overlap area of ​​the material conveying and assembly devices during rotation (the overlap area can be understood as the tangent point of two tangent circles), the material can only be released at the moment when the material on each material conveying mechanism coincides with the mold cavity or insert trajectory of the forming mold during rotation. The timing of material feeding is difficult to grasp (feeding too early or too late will result in misalignment), which directly affects the feeding accuracy and assembly quality.

[0004] To improve material feeding accuracy in existing material conveying and assembly systems, one approach is to enhance the design, manufacturing, and assembly levels of related system components, and to equip them with precise and rapid industrial control systems. This improves the operational accuracy and synchronization of the material conveying and assembly devices, thereby increasing feeding accuracy. However, as the required feeding accuracy increases (for example, when the product size is very small, the mold cavity and insert openings will be very small, requiring even higher feeding accuracy), the cost of these methods increases exponentially. Alternatively, one can reduce the rotation speed of the material conveying and assembly devices (stopping briefly at the aligned position to feed material, then continuing to rotate after feeding) to extend the time for the material to overlap with the mold cavity or insert, thus improving feeding accuracy. However, this significantly impacts production efficiency.

[0005] In traditional compression molding technology, a material extrusion device (commonly known as a turret) is typically used in conjunction with a material conveying and assembly system. The material extrusion device is fixed in position and has an extrusion orifice at its top. Molten material is uniformly extruded through the orifice at a preset speed for pickup by the material conveying mechanism. A typical material conveying mechanism includes a cutter that, as it rotates and passes over the extrusion orifice, quantitatively scrapes off the material.

[0006] To improve material feeding accuracy, existing material conveying and assembly systems attempt to shorten the height distance between the material and the mold cavity or insert during feeding, thereby reducing accuracy errors caused by the material's free fall time. Existing systems shorten this height distance by moving the material conveying mechanism, which can move up and down, lowering it closer to the mold cavity or insert during feeding. The disadvantage is that over time, the accuracy of the material conveying mechanism's vertical movement can deviate, leading to decreased accuracy in the cutter's scraping of material (too high a cutter results in less material, too low a cutter results in more material). Furthermore, the distance between the cutter and the material extrusion device is already very close during normal scraping; if the cutter's stroke is too low, it can easily rub against the extrusion device, damaging the cutter edge (cutters are typically made of aluminum, while the extrusion device is made of steel), increasing maintenance costs and downtime during production. Summary of the Invention

[0007] The purpose of this invention is to provide a material transportation and assembly system.

[0008] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0009] A material transport and assembly system includes a material conveying device and a material assembly device. The material conveying device has multiple sets of material conveying mechanisms spaced circumferentially, and the material assembly device has multiple sets of forming molds spaced circumferentially. The material conveying device includes a first gear and a first rotating shaft, and the material assembly device includes a second gear and a second rotating shaft. The first gear meshes with the second gear. The material conveying device also includes a first track plate and a slider. The material conveying mechanisms are correspondingly disposed on the slider. The first track plate has a track groove to limit the running trajectory of the slider.

[0010] The track groove includes a synchronization section located near the material assembly device. The synchronization section is an arc concentric with the material assembly device, so that when the slider passes through the synchronization section, the material on the material conveying mechanism coincides with the trajectory of the mold cavity or insert on the forming mold.

[0011] As a further improved technical solution of the present invention, the material conveying device further includes a slider guide plate and a slider support plate. The slider guide plate is connected to the first rotating shaft to drive the slider to rotate. The slider guide plate is provided with a guide groove in the radial direction so that the slider has a radial movement space and can run along the track groove when the slider rotates.

[0012] The track groove is equipped with a first bearing, which is connected to the slider.

[0013] As a further improved technical solution of the present invention, the material conveying mechanism includes a cutter, a feeding rod, a second bearing, a bearing seat, and a first connecting rod. The cutter is fixedly connected to the slider through the first connecting seat and the connecting column. The feeding rod is fixedly connected to the first connecting rod, the bearing seat, and the second bearing as an integral structure through the second connecting seat. A return spring is provided between the bottom of the bearing seat and the top of the slider to provide an upward return thrust for the feeding rod.

[0014] The material conveying device also includes a second track plate. The bottom of the second track plate is provided with a first guide surface that cooperates with the second bearing, so as to press the feed rod downward when the slider passes through the synchronization section, and push the material on the cutter down.

[0015] As a further improved technical solution of the present invention, the material assembly device includes an assembly plate and a third track plate, and the forming mold is provided with a third bearing that cooperates with the third track plate;

[0016] The assembly plate is connected to the second rotating shaft to drive the molding die to rotate.

[0017] The third track plate is provided with a second guide surface to control the opening and closing action of the molding mold when the molding mold rotates with the assembly plate, so that the molding mold opens when it is close to the synchronous section and closes when it is far away from the synchronous section.

[0018] As a further improved technical solution of the present invention, the material assembly device further includes a pressure feeder, a second connecting rod, a pressure spring, a fourth bearing, and a fourth track plate. The pressure feeder is correspondingly arranged with the forming mold and is used to press and fix the inserts on the forming mold.

[0019] The pressure feeder is connected to one end of the second connecting rod, the fourth bearing is connected to the other end of the second connecting rod, and the two ends of the pressure spring are respectively in abutting contact with the assembly plate and the second connecting rod to provide pressure for the pressure feeder to press and fix the insert on the molding die;

[0020] The fourth track plate is provided with a third guide surface to control the pressing action of the pressure device when the pressure device rotates with the assembly plate.

[0021] As a further improvement of the present invention, the material conveying mechanism further includes an air supply pipe, the air outlet of which leads to the bottom of the feed rod, so as to blow the material on the cutter down with the assistance of airflow.

[0022] As a further improvement of the present invention, an anti-wear pad is fixedly provided on the top of the slider at the point where it cooperates with the reset spring, and the anti-wear pad is detachably connected to the slider.

[0023] As a further improvement of the present invention, the third track plate is disposed at the bottom of the forming mold, and the bottom of the lower mold of the forming mold is provided with a third bearing that cooperates with the third track plate.

[0024] As a further improvement of the present invention, the second guide surface is provided with an upwardly protruding approach section, so that the lower mold of the forming mold moves upward when it approaches the feeding point, thereby shortening the feeding distance.

[0025] As a further improvement of the present invention, the first guide surface is an arc-shaped surface with a lower middle section and higher ends.

[0026] Compared with the prior art, the technical advantages of the present invention are as follows:

[0027] This invention utilizes a synchronous section on the track groove that works in conjunction with a slider. As the slider passes through the synchronous section, it causes the material conveying mechanism to adjust its radial position within the material conveying device. This results in a longer trajectory overlap between the material on the conveying mechanism and the mold cavity or insert on the forming die. This extends the overlap time between the material and the mold cavity or insert, allowing for better control of the feeding timing (feeding only needs to occur within the trajectory overlap range), thus improving feeding accuracy and assembly quality. Furthermore, improving feeding accuracy by extending the trajectory overlap range is relatively low-cost, and feeding does not require interruptions, thus not affecting production efficiency.

[0028] By setting a proximity section on the second guide surface of the third track plate, the lower die of the forming mold moves upward as it approaches the feeding point, thereby shortening the material feeding distance and reducing accuracy errors caused by feeding time. The fixed height of the cutter prevents deviations in the accuracy of its vertical movement after prolonged use, which could lead to decreased accuracy in material scraping and damage to the cutter blade due to friction between the cutter and the material extrusion device. This improves the operational stability of the material transport and assembly system, and reduces maintenance costs and downtime. Attached Figure Description

[0045] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0046] Please refer to Figures 2 to 16. A material transport and assembly system includes a material conveying device 100 and a material assembly device 200. The material conveying device 100 has multiple sets of material conveying mechanisms 101 spaced circumferentially, and the material assembly device 200 has multiple sets of forming molds spaced circumferentially. The material conveying device 100 includes a first gear 1 and a first rotating shaft 2, and the material assembly device 200 includes a second gear 3 and a second rotating shaft 4. The first gear 1 and the second gear 3 mesh. When the material transport and assembly system is running, the first rotating shaft 2 and the second rotating shaft 4 drive the material conveying device 100 and the material assembly device 200 to rotate synchronously in opposite directions. The material conveying mechanisms 101 are paired with the forming molds one by one to complete the assembly work.

[0047] The material conveying device 100 also includes a first track plate 5 and a slider 6. Each set of material conveying mechanisms 101 is correspondingly mounted on a slider 6. The first track plate 5 is provided with a track groove 51 to limit the running trajectory of the slider 6. Specifically, when the material conveying mechanism 101 rotates under the drive of the first rotating shaft 2, it follows the slider 6 along the track groove 51 on the first track plate 5.

[0048] The track groove 51 includes a synchronization section 511 located near the material assembly device 200. The synchronization section 511 is an arc shape concentric with the material assembly device 200 (and concentric with the second rotating shaft 4), so that when the slider 6 passes through the synchronization section 511, the material (not shown) on the material conveying mechanism 101 coincides with the trajectory of the mold cavity or insert (not shown) on the molding die. Whether the assembly is completed by the mold cavity or the insert on the molding die depends on the type of product produced by compression molding. When the product produced by compression molding is a pure plastic one-time molding product, such as a sealing ring, the molding is completed by pressing through the mold cavity. When the product produced by compression molding is a plastic part processed on a semi-finished product, such as a sealing ring processed on a bottle cap, the insert (e.g., the bottle cap) is placed and fixed on one side of the molding die, and the material falling into the insert is pressed by the mold on the other side to complete the molding.

[0049] The track groove 51 is specifically divided into a synchronous section 511, a transition section 512, and a traveling section 513. The traveling section 513 is an arc shape concentric with the material conveying device 100 (and concentric with the first rotating shaft 2). The transition section 512 is located at both ends of the synchronous section 511 and is used for a smooth transition between the traveling section 513 and the synchronous section 511. When the slider 6 enters the transition section 512 from the traveling section 513, it will carry the material conveying mechanism 101 to move radially in the material conveying device 100 until it enters the synchronous section 511, adjusting the movement trajectory of the material on the material conveying mechanism 101 to be directly above the movement trajectory of the mold cavity or insert on the molding die. Because the material can be kept directly above the mold cavity or insert within the stroke range of the synchronous section 511, the timing of feeding is easier to control. Even if the material is fed a little earlier or later, as long as the slider 6 is still in the synchronous section 511, the material can be accurately fed into the assembly point of the mold cavity or insert. Preferably, the feeding point of the material conveying mechanism 101 is aligned with the middle of the synchronization section 511.

[0050] The material conveying device 100 also includes a slider guide plate 7 and a slider support plate 8. The slider guide plate 7 is connected to the first rotating shaft 2 to drive the slider 6 to rotate. The slider guide plate 7 is provided with a guide groove 71 along the radial direction so that the slider 6 has a radial movement space. When the slider 6 rotates, it can run along the track groove 51.

[0051] Preferably, the slider support plate 8 is also connected to the first rotating shaft 2 and rotates with the first rotating shaft 2 to reduce frictional loss with the slider 6.

[0052] The track groove 51 is equipped with a first bearing 9, which is correspondingly connected to the slider 6. Specifically, the first bearing 9 and the slider 6 are arranged in a one-to-one correspondence, the axis of the first bearing 9 is vertical, and it is fixed to the bottom of the slider 6 by bolts. The first bearing 9 is used to make rolling contact with the side wall of the track groove 51, so that the slider 6 runs more smoothly along the track groove 51.

[0053] The material conveying device 100 also includes a fixed plate 10 and an air duct plate 11. The fixed plate 10 is used to install the second track plate 12 described below. The position of the fixed plate 10 is fixed, just like the first track plate 5, and does not rotate with the first rotating shaft 2. The air duct plate 11 is provided with an air duct to provide an air passage connection for the air supply pipe 13 described below. Preferably, the air duct plate 11 is connected to the first rotating shaft 2 and rotates with the first rotating shaft 2.

[0054] Furthermore, the material conveying mechanism 101 includes a cutter 14, a feeding rod 15, a second bearing 16, a bearing seat 17, and a first connecting rod 18. The cutter 14 is fixedly connected to the slider 6 through a first connecting seat 19 and a connecting column 20.

[0055] Specifically, the cutter 14 is fixed on the first connecting seat 19 with the blade facing downwards. The first connecting seat 19 is fixedly connected to the slider 6 via two connecting posts 20. The cutter 14 only moves horizontally with the slider 6 and does not move vertically.

[0056] The feeding rod 15 is fixedly connected to the first connecting rod 18, the bearing seat 17, and the second bearing 16 as an integral structure via the second connecting seat 21. A return spring 22 is provided between the bottom of the bearing seat 17 and the top of the slider 6 to provide an upward return thrust for the feeding rod 15.

[0057] Specifically, the feed rod 15 is located inside the cutter 14 and is fixedly connected to the second connecting seat 21. The first connecting rod 18 passes through the slider 6 and is fixedly connected at both ends to the bearing seat 17 and the second connecting seat 21 by bolts. The second bearing 16 is fixedly connected to the bearing seat 17. The return spring 22 is sleeved on the first connecting rod 18 and pushes the feed rod 15 upward.

[0058] The material conveying device 100 also includes a second track plate 12, which is fixedly positioned on the fixed plate 10 and aligned with the synchronous section 511. The bottom of the second track plate 12 is provided with a first guide surface 121 that cooperates with the second bearing 16, so as to press the feed rod 15 downward when the slider 6 passes through the synchronous section 511, and push the material on the cutter 14 down.

[0059] Specifically, when the slider 6 passes through the synchronization section 511, the second bearing 16 rolls over the first guide surface 121. The pressure from the first guide surface 121 causes the feed rod 15 to move downward against the push of the return spring 22. When the second bearing 16 rolls to the lowest point of the first guide surface 121, the feed rod 15 also moves to the lowest point, pushing the material on the cutter 14 down.

[0060] During the design process, the downward pressing speed of the feeding rod 15 can be controlled by the curvature of the first guide surface 121. The greater the curvature of the first guide surface 121, the faster the downward pressing speed of the feeding rod 15. The feeding point position of the material conveying mechanism 101 can also be adjusted by selecting the lowest point position of the first guide surface 121.

[0061] Preferably, the first guide surface 121 is an arc-shaped surface with a lower middle section and higher ends. The lowest point of the middle section of the first guide surface 121 is aligned with the middle position of the synchronization section 511 so that the feeding point of the material conveying mechanism 101 is aligned with the middle of the synchronization section 511.

[0062] The material assembly device 200 includes an assembly plate 24 and a third track plate 25. The forming mold is provided with a third bearing 26 that cooperates with the third track plate 25.

[0063] The molding die is set on the assembly plate 24, which is connected to the second rotating shaft 4 to drive the molding die to rotate.

[0064] The third track plate 25 is provided with a second guide surface 251 to control the opening and closing action of the molding mold when the molding mold rotates with the assembly plate 24, so that the molding mold opens when it is close to the synchronization section 511 and closes when it is far away from the synchronization section 511.

[0065] Furthermore, in this embodiment, the third track plate 25 is disposed at the bottom of the molding die, and the bottom of the lower die 27 of the molding die is provided with a third bearing 26 that cooperates with the third track plate 25. The third bearing 26 rolls in contact with the second guide surface 251, and the opening and closing action of the molding die is controlled by the undulation of the second guide surface 251.

[0066] In other embodiments, it is not excluded that the third track plate 25 may be disposed on the top of the forming mold, and the top of the upper mold 28 of the forming mold may be provided with a third bearing 26 that cooperates with the third track plate 25.

[0067] Furthermore, the second guide surface 251 is provided with an upwardly protruding approach section 2511, so that the lower mold 27 of the forming mold moves upward when it approaches the feeding point, thereby shortening the feeding distance.

[0068] It should be noted that the approach section 2511 protrudes upward relative to the second guide surfaces 251 on both sides of the approach section 2511. The second guide surfaces 251 on both sides of the approach section 2511 are lower than the approach section 2511, so that the lower mold 27 is in a fully open state to avoid interference with the material conveying mechanism 101.

[0069] Preferably, the highest point of the approach section 2511 on the second guide surface 251 is aligned with the lowest point of the middle part of the first guide surface 121, so that the lower die 27 moves to the position closest to (without contacting) the cutter 14 at the feeding point, thereby minimizing the material dropping distance.

[0070] When the product produced by compression molding is a one-time molded product made of pure plastic, the material assembly device 200 may not be equipped with a pressure feeder 29.

[0071] When the product produced by compression molding is a plastic part processed on a semi-finished product, the material assembly device 200 also includes a pressure feeder 29, a second connecting rod 30, a pressure spring 31, a fourth bearing 32, and a fourth track plate 33 (the fourth track plate 33 is located on the inner periphery of the third track plate 25). In this embodiment, the pressure feeder 29 is correspondingly arranged with the lower mold 27 of the molding die and is used to press and fix the insert on the lower mold 27.

[0072] The pressure feeder 29 is fixedly connected to one end of the second connecting rod 30, and the fourth bearing 32 is fixedly connected to the other end of the second connecting rod 30. The two ends of the pressure spring 31 are respectively in abutting contact with the assembly plate 24 and the second connecting rod 30, providing downward pressure to the pressure feeder 29 to press and fix the insert on the lower mold 27, preventing the insert from moving or falling off the lower mold 27 during the assembly process.

[0073] The fourth track plate 33 is provided with a third guide surface 331 to control the clamping action of the pressure device 29 as it rotates with the assembly plate 24. The pressure device 29 is raised as the third guide surface 331 rises and lowered as the third guide surface 331 falls. It should be noted that the pressure spring 31 should be designed to provide sufficient downward pressure to the pressure device 29 even when it is at the lowest point of the third guide surface 331.

[0074] It should be noted that the third guide surface 331 in the figure follows the rise and fall of the second guide surface 251, which is used to show the process of the pressure plater 29 and the lower die 27 moving together and pressing the insert on the lower die 27.

[0075] Those skilled in the art will readily recognize that during the process of placing the insert onto the lower die 27, the lower die 27 should be opened before the insert is loaded, and the pressure platen 29 should be positioned above the lower die 27. After the insert is placed onto the lower die 27, the pressure platen 29 moves downward, pressing down on the insert and moving with the lower die 27. The motion control of the lower die 27 and the pressure platen 29 during the process of placing the insert onto the lower die 27 can also be achieved through the design of the height variations of the second guide surface 251 and the third guide surface 331.

[0076] Preferably, the material conveying mechanism 101 further includes an air supply pipe 13 (the connection between the air supply pipe 13 and the air duct plate 11 is not shown in the figure). The air outlet of the air supply pipe 13 leads to the bottom of the feeding rod 15, so as to blow the material on the cutter 14 down with the assistance of airflow. Molten material may occasionally stick to the feeding rod 15 during feeding. Feeding with airflow assistance can make the feeding process smoother. It should be noted that feeding with airflow assistance is a prior art. However, in the prior art, because the feeding time is only a moment, the airflow is designed to be strong. When the material weight is small, it is easy to be blown away by the jet of airflow. In this application, since feeding can be carried out in the entire trajectory overlap range corresponding to the synchronous segment 511, the airflow can be appropriately reduced, which is beneficial to the production of small weight compression molded products.

[0077] Preferably, an anti-wear pad 36 is fixedly provided on the top of the slider 6 at the point where it mates with the return spring 22, and the anti-wear pad 36 is detachably connected to the slider 6. The bottom end of the return spring 22 presses against the anti-wear pad 36 to prevent wear on the slider 6. After the anti-wear pad 36 wears, it can be removed from the slider 6 for replacement.

[0078] Compared with the prior art, the technical advantages of the present invention are as follows:

[0079] This invention utilizes a synchronization section 511 on the track groove 51 to cooperate with the slider 6. As the slider 6 passes through the synchronization section 511, it moves the material conveying mechanism 101 to a radially adjusted position within the material conveying device 100. This results in a longer trajectory overlap between the material on the material conveying mechanism 101 and the mold cavity or insert on the forming mold, thereby extending the trajectory overlap time between the material and the mold cavity or insert. This allows for better control of the feeding timing (feeding only needs to be done within the trajectory overlap range), improving material feeding accuracy and assembly quality. Furthermore, improving feeding accuracy by extending the trajectory overlap range is relatively low-cost, and feeding does not require interruptions, thus not affecting production efficiency.

[0080] By setting a proximity section 2511 on the second guide surface 251 of the third track plate 25, the lower die 27 of the forming mold moves upward when it approaches the feeding point, thereby shortening the feeding distance and reducing the accuracy error caused by feeding time. The fixed height of the cutter 14 avoids deviations in the accuracy of its vertical movement after prolonged use, which could lead to decreased accuracy in scraping material and damage to the cutter's blade due to friction between the cutter 14 and the material extrusion device. This improves the operational stability of the material transport and assembly system and reduces its maintenance costs and downtime.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
