Description

Technical Field

[0001] This utility model relates to the technical field of strip profile production, specifically to a multi-station turntable mechanism. Background Technology

[0002] For the production process of long strip-shaped workpieces, since the length of the strip is generally quite long, each process means that the length and area of ​​the entire production line will be greatly expanded. Also affected by its length, it is easy to twist or bend during the transfer process, and relying on manual operation will greatly reduce work efficiency. Utility Model Content

[0003] This utility model proposes a multi-station turntable mechanism that integrates several processes into one. Each position is equipped with a dedicated auxiliary mechanism, allowing for simultaneous processing without interruption. Multiple processing operations can be achieved through a single station, eliminating the need for transfer and greatly improving production efficiency while saving equipment space.

[0004] Therefore, the technical solution adopted is as follows: A multi-station turntable mechanism for supporting and limiting strip profiles includes several coaxially spaced support discs that rotate synchronously in the vertical direction. Each support disc has several locking grooves at equal angles around its central axis, matching the shape of the profile. Each support disc has a feeding platform and a discharging platform on its two sides. The feeding platform has a robotic arm, and the discharging platform has a discharging hook, a pusher plate, and a conveyor chain that reciprocate along a direction perpendicular to the length of the profile. The discharging hook can penetrate the inner side of the support disc, deeper than the locking grooves, and pull the profile onto the conveyor chain. The end point of the conveyor chain is located within the working stroke of the pusher plate, and the end point of the pusher plate's stroke is located at the discharging edge of the discharging platform.

[0005] A further technical solution includes a locking assembly, which includes an arc-shaped locking rod that fits the shape of the support plate. The locking rod has several locking teeth that match the shape of the profile. The locking rod is driven by a locking cylinder to approach or move away from the locking groove, so that the locking teeth engage or disengage from the opening of the sheath current collector. The number of locking teeth is equal to the number of locking grooves 11 that need to be inserted to fix the inner sheath, and their positions correspond.

[0006] A further technical solution is that the discharge platform has a discharge support arm below its edge, and a discharge conveying roller is located below the discharge support arm. The discharge conveying roller has a clearance opening to allow the discharge support arm to descend below its conveying surface. The discharge conveying roller is connected to the feed port of the packaging machine.

[0007] A further technical solution is that one side of the feeding platform has a material shaping platform, and a sliding truss is erected between the material shaping platform and the feeding platform, and the robotic arm slides on the sliding truss.

[0008] A further technical solution is that the feeding platform also has a limiting component, which includes a limiting plate vertically fixed on the limiting platform. The limiting plate has a rotating plate on the side near the support plate. The rotating plate is driven by an elastic element to move closer to the limiting plate around the rotation axis. There is a placement gap between the limiting plate and the rotating plate to accommodate the profile and match the profile's external dimensions. The feeding platform also has a push rod, which moves back and forth in a direction perpendicular to the profile's length. The distance between the starting point of its stroke and the support plate is greater than the distance between the limiting plate and the support plate, and the ending point is close to the surface of the support plate.

[0009] A further technical solution is that the push rod is horizontally arranged, and vertically arranged support rods are symmetrically fixed at both ends. The support rods are driven to move by a push cylinder. An insertion plate matching the profile shape is fixed on the side of the push rod that is close to the support plate. An auxiliary baffle is fixed on the top of the push rod.

[0010] A further technical solution is that the discharge platform also has a chip removal component, which includes a chip removal brush and a drive mechanism for rotating the chip removal brush. The discharge platform has a chip removal push plate arranged in the same direction as the conveyor chain. When the profile falls from the conveyor chain onto the discharge platform, it enters the stroke of the chip removal push plate. The chip removal component is located at the end of the stroke of the chip removal push plate and has two sets arranged opposite to each other and located at both ends of the profile. At the same time, the two chip removal brushes contact the two end faces of the profile respectively.

[0011] A further technical solution includes several auxiliary components, the angular interval between every two auxiliary components being the same as or a multiple of the angular interval between every two snap-fit ​​slots, the auxiliary components being cutting components, including a cutting disc that moves back and forth toward the profile to be cut and a second driving mechanism that drives the cutting disc to rotate, the cutting disc being perpendicular to the profile.

[0012] A further technical solution includes several auxiliary components, the angular interval between every two auxiliary components being the same as or a multiple of the angular interval between every two snap-fit ​​slots, the auxiliary components being grinding components, including a grinding wheel and a drive mechanism for driving the grinding wheel to rotate, the outer edge of the grinding wheel abutting against the chamfered position on the end face of the profile.

[0013] A further technical solution is that the discharge edge of the discharge platform has a receiving rod that extends and retracts along the discharge direction, and the receiving rod is located above the discharge support arm.

[0014] The working principle and beneficial effects of this application are as follows: 1. This mechanism is mainly used in the production of strip profiles such as sliding contact lines. It integrates several processes into one, and each position is equipped with a dedicated auxiliary mechanism, which can process simultaneously without stopping the machine in between. Multiple processing can be achieved through one workstation without the need for transfer, which greatly improves production efficiency and saves the space occupied by the equipment.

[0015] 2. The material is hooked out by the discharge hook, pusher plate and conveyor chain. The discharge hook is stably conveyed by the chain to ensure that the direction of the material does not change. The conveyor chain holds the material at the pusher plate position. By controlling the pushing frequency of the pusher plate, it is possible to control how many material profiles are loaded. It can achieve the discharge effect of multiple material profiles laid flat and stacked layer by layer. The material groups stacked as required can be directly sent to the packaging machine, saving packaging operations and improving packaging efficiency.

[0016] 3. By using the limiting component, after the robotic arm grabs the profile, it is placed on the limiting component to maintain the orientation angle. Then, the pusher rod pushes it into the corresponding clamping groove to ensure the accurate feeding position of the profile and prevent it from being deformed due to the influence of material and length, which would affect subsequent processing and improve the stability of equipment production.

[0017] 4. The chip removal component removes metal dust from the edges of the profiles, making it easier to pack them directly without the need for manual chip removal. This improves the production process of strip profiles and ensures fully automated operation and production of the equipment. Attached Figure Description

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] like Figures 1-11 As shown, a multi-station turntable mechanism for supporting and limiting strip profiles 100 includes several coaxially spaced support disks 1 that rotate synchronously in the vertical direction. Each support disk 1 has several locking grooves 11 at equal angles around its central axis, matching the shape of the profile 100. Each support disk 1 has a feeding platform 12 and a discharging platform 13 on its two sides. A robotic arm 14 is located at the feeding platform 12 and can perform work by being mounted on a sliding truss 40. The discharging platform 13... Platform 13 has a discharge hook 15, a pusher plate 16, and a conveyor chain 17 that move back and forth along the length direction perpendicular to the profile 100. The discharge hook 15 can penetrate into the inner side of the support plate 1, deeper than the snap-fit ​​groove 11, and pull the profile 100 onto the conveyor chain 17. The conveying end point of the conveyor chain 17 is located within the working stroke of the pusher plate 16, and the stroke end point of the pusher plate 16 is located at the discharge edge of the discharge platform 13. The discharge hook 15, the pusher plate 16, and the conveyor chain 17 are all driven by corresponding power sources.

[0023] In use, a profile 100 is secured in several corresponding snap-fit ​​slots 11 on several support plates 1. Components can be arbitrarily matched with the snap-fit ​​slots 11 to achieve the desired work pattern at that position. By synchronously rotating several support plates 1, the profile 100 is sequentially transferred to the next process position for further processing. As long as the number of snap-fit ​​slots 11 is greater than the required number of processes, simultaneous work can be achieved for each process without mutual interference.

[0024] Several locking slots 11 correspond to several auxiliary components. The angular interval between every two auxiliary components is the same as or a multiple of the angular interval between every two locking slots 11. Each auxiliary component can be adjusted and changed according to different strip profile 100 production processes. When the strip profile 100 is a sliding contact line, the auxiliary components are a cutting component 7 and a grinding component 8. The cutting component 7 includes a cutting disc 71 that moves back and forth toward the profile 100 to be cut and a second driving mechanism 72 that drives the cutting disc 71 to rotate. The cutting disc 71 is perpendicular to the profile 100. The grinding component 8 includes a grinding wheel 81 and a first driving mechanism 82 that drives the grinding wheel 81 to rotate. The outer edge of the grinding wheel 81 abuts against the end face of the profile 100 at the position to be chamfered.

[0025] In this embodiment, a turntable mechanism is used to insert sheaths onto the steel-aluminum composite profile 100 during the production of the sliding contact line. The sheath insertion process requires at least four stations. Considering work efficiency, it is preferable to design eight locking slots 11. This ensures that the locking slots 11 for the sheath feeding process and the locking slots 11 for the discharging process are positioned opposite each other and both can operate horizontally. For example, this embodiment... Figure 5 As shown, each side of the support plate 1 has a locking groove 11 corresponding to the height of the feeding platform 12 and the discharging platform 13, respectively, which facilitates the entry or exit of the sheath or sliding contact line. There are also three locking grooves 11 symmetrically arranged vertically between the two locking grooves 11. Counting according to the rotation direction of the support plate 1, the first locking groove 11 is used to accommodate the sheath to be processed, the second is used to insert the composite part into the sheath and cut the steel strip, and the third is used to chamfer the end face of the sliding contact line. The purpose of setting eight locking grooves 11 is to ensure that the five stations, including the feeding and discharging processes, work continuously. At the same time, it ensures that the angles of the locking grooves 11 are evenly distributed so that the locking grooves 11 at the feeding and discharging positions are at the same height, that is, on the same horizontal plane. The feeding platform 12 and the discharging platform 13 are set at the same height to facilitate horizontal feeding and discharging.

[0026] During the process, the feeding platform 12 has a material table 4 on one side for placing the sheath profile 100. The robotic arm 14 grabs the sheath profile 100 for loading, places the sheath on the feeding platform 12, and then pushes it into the snap-fit ​​groove 11, which is located at the same horizontal plane as the feeding platform 12, through a horizontal pushing mechanism. The horizontal pushing mechanism can be a working component such as a cylinder. After entering the snap-fit ​​groove 11, the sheath profile 100 rotates with the support plate 1 to the next processing station to prepare for the next sheath insertion. At this time, a new empty snap-fit ​​groove 11 is also available at the previous feeding position. The position awaits feeding. After the sleeve insertion process is completed in the next snap-fit ​​groove 11 and the steel strip is cut off by the downward cutting disc 71, the support disc 1 continues to rotate so that the snap-fit ​​groove 11 in the original processing position is aligned with the composite mechanism to become a new sleeve insertion station. Sleeve insertion and steel strip cutting operations are performed. This cycle is repeated. In the next step, the sliding contact line continues to chamfer the steel strip through the chamfering wheel. Finally, it rotates to the discharge station to discharge the material. Each time the support disc 1 rotates, each process performs work synchronously. After all the work is completed, the support disc 1 rotates again to allow the workpiece in each snap-fit ​​groove 11 to proceed to the next process.

[0027] During discharge, a discharge support arm 19 is located below the edge of the discharge platform 13. Below the discharge support arm 19 is a discharge conveyor roller 18. The discharge conveyor roller 18 has a clearance opening 190 to allow the discharge support arm 19 to descend below its conveying surface. The discharge conveyor roller 18 is connected to the feed port of the baler 3. First, the discharge hook 15 pulls out the sliding contact line and moves it onto the conveyor chain 17. The conveyor chain 17 conveys the sliding contact line into the working stroke of the pusher plate 16. After accumulating a certain number, such as 5, the pusher plate 16 pushes it off the edge of the discharge platform 13 onto the discharge support arm 19 to wait. This is the stacking process. The first layer continues in this manner. After accumulating 5 more on the discharge platform 13 within the working stroke of the pusher plate 16, the discharge support arm 19 descends to the corresponding height, and the pusher plate 16 pushes down the new 5 sliding contact lines to pile them onto the first layer until the number and height of the stacks meet the requirements. At this time, the discharge support arm 19 drives the entire structure back to the discharge conveyor roller 18 and gradually descends from the clearance opening 190 to below the conveying surface of the discharge conveyor roller 18. At this time, the sliding contact lines will be directly mounted on the discharge conveyor roller 18 and then fed into the packaging machine 3 for packaging. After packaging, they can be placed on the finished product platform by the robotic arm or conveying mechanism.

[0028] Based on this, such as Figure 2As shown, the discharge platform 13 also has a chip removal component 6, which includes a chip removal brush 61 and a drive mechanism 62 for rotating the chip removal brush 61. The discharge platform 13 has a chip removal pusher plate 63 arranged in the same direction as the conveyor chain 17. When the profile 100 falls from the conveyor chain 17 onto the discharge platform 13, it enters the stroke of the chip removal pusher plate 63. The chip removal component 6 is located at the end of the stroke of the chip removal pusher plate 63, and has two sets arranged opposite to each other and located at both ends of the profile 100. At the same time, the two chip removal brushes 61 contact the two end faces of the profile 100 respectively. After the surface of the profile 100 is generally cut or processed, burrs or metal chips will be generated or adsorbed. The chip removal component 67 sweeps away the metal chip powder and polishes the surface of the profile 100, which facilitates direct packaging in the later stage. There is no need for manual chip removal operation. This improves the production process of the profile 100 in detail and ensures the fully automated operation and production of the equipment.

[0029] In addition, the discharge platform 13 has a receiving rod 191 at its discharge edge that extends and retracts along the discharge direction. The receiving rod 191 is located above the discharge support arm 19. The receiving rod 191 is used to receive the pushed-down profile 100, playing a role in buffering and stabilizing.

[0030] Therefore, as a whole, when the profiles 100, such as the sliding contact line, fall from the conveyor chain 17 onto the discharge platform 13, they first enter the stroke of the chip removal pusher 63. The chip removal pusher 63 then pushes them into the range of the chip removal assembly 6 for fixation and chip removal. The chip removal assembly 6 has a pressing mechanism on one side, which can use a cylinder to fix the profiles 100 located at the chip removal position for easy grinding and chip removal. When the profiles 100 in this position are stacked in a row and accumulate to a specified number and the chip removal is completed, the pusher plate 16 pushes them to the discharge edge of the discharge platform 13 and they fall. At this time, the receiving rod 191 extends and catches the falling row of profiles 100. The receiving rod 191 is close to the discharge platform 13, which buffers and stabilizes the profiles 100. The receiving rod 191 retracts after the profile 100 is stabilized, and the discharge support arm 19, located at the bottom of the receiving rod 191, finally catches the profile 100. Since the diameter of the receiving rod 191 is small and it is close to the upper surface of the discharge support arm 19, the falling distance of the entire row of profiles 100 is shortened, so that they can fall stably onto the discharge support arm 19, forming the first layer of the profile stack. The above operation is repeated so that the profiles 100 are stacked layer by layer on the discharge support arm 19. After the required number of layers for packaging and transportation is reached, the discharge support arm 19 drives the entire stack of profiles to be transported to the discharge conveyor roller 18 and falls to place them on the conveying surface for transmission to the subsequent packaging machine 3.

[0031] To ensure the connection strength between the profile 100 and the snap-fit ​​groove 11 and to prevent displacement during operation, another embodiment of this application also includes a locking assembly 2. The locking assembly 2 includes an arc-shaped locking rod 21 that fits the shape of the support plate 1. Several locking teeth 22 that match the shape of the profile 100 are fixed on the locking rod 21. The locking rod 21 is driven by a locking cylinder 23 to approach or move away from the snap-fit ​​groove 11, causing the locking teeth 22 to engage or disengage from the opening of the sheath current collector. The number of locking teeth 22 is equal to the number of snap-fit ​​grooves 11 that need to be inserted to fix the internal sheath, and their positions correspond. Thus, when the profile 100 is located inside the locking groove 11, the locking cylinder 23 drives the locking rod 21 to approach the locking groove 11, causing the locking teeth 22 to engage with the groove of the profile 100. When the support plate 1 needs to rotate, the locking cylinder 23 retracts to avoid interfering with the locking groove 11. When the rotation is completed, it engages with the locking groove 11 again to ensure the stability of the profile 100. Referring to the above embodiment, the locking teeth 22 are needed to engage and fix the three corresponding positions of the locking groove 11 for accommodating the sheath to be processed, inserting the composite part into the sheath, cutting the steel strip, and chamfering the end face of the sliding contact line. However, the locking groove 11 corresponding to the feeding and discharging stations does not need to be matched with corresponding locking teeth 22 because it is used for feeding or discharging the sheath or sliding contact line.

[0032] like Figure 7 and Figure 9 As shown, one embodiment of the feeding platform 12 further includes a limiting component 5. The limiting component 5 includes a limiting plate 51 vertically fixed on the limiting platform. The limiting plate 51 has a rotating plate 52 on the side near the support plate 1. The rotating plate 52 is driven by an elastic element to move closer to the limiting plate 51 around the rotation axis. There is a placement gap between the limiting plate 51 and the rotating plate 52 to accommodate the profile 100 and match the external dimensions of the profile 100. The feeding platform 12 also has a push rod 53. The push rod 53 moves back and forth in a direction perpendicular to the length of the profile 100, and the distance between the starting point of its stroke and the support plate 1 is greater than the distance between the limiting plate 51 and the support plate 1, and the ending point is close to the surface of the support plate 1.

[0033] Thus, after the robotic arm 14 grasps the profile 100, it is placed between the limiting plate 51 and the rotating plate 52 to ensure the stable orientation and position of the profile 100 without twisting. The limiting plates 51 and the rotating plate 52 on both sides have a certain guiding and limiting effect on the orientation of the profile 100. When feeding is required, the push rod 53 pushes the profile 100 into the locking groove 11. Since the rotating plate 52 is supported by the elastic element, it will not interfere with the release of the profile 100. It will be pressed down by the profile 100 and then reset and bounced up by the elastic element. Through the limiting component 5, the robotic arm 14 grasps the profile 100 and places it on the limiting component 5 to maintain the orientation angle. Then, the push rod 53 pushes it into the corresponding locking groove 11 to ensure the accurate feeding orientation of the profile 100 and prevent it from being deformed due to the influence of material and length, which would affect subsequent processing and improve the stability of equipment production.

[0034] Based on this, the push rod 53 is horizontally set, and vertically set support rods 531 are symmetrically fixed at both ends. The support rods 531 are driven by a cylinder to move. The support rods 531 are used to support and apply force to the push rod 53, ensuring that the force exerted by the push rod 53 on the profile 100 is uniform and stable. An insertion plate 532 matching the shape of the profile 100 is fixed on the side of the push rod 53 that is close to the support plate 1. The insertion plate 532 is inserted into the profile 100, further ensuring that the angle of each grabbed profile 100 is consistent and that it is locked in place by the insertion plate 532. At the same time, an auxiliary baffle 533 is fixed on the top of the push rod 53. The auxiliary baffle 533 abuts against the profile 100, further ensuring that the profile 100 will not rotate or move.

[0035] Overall, the equipment can integrate several processing steps according to the actual situation, while saving processing space and improving production efficiency by utilizing the support plate 1. It is also equipped with auxiliary accessories such as limit components 5 and chip removal components 6 to ensure that the sliding profile 100 will not cause downtime, require rework by operators, or result in unqualified product quality during the automated production process due to twisting or burrs. It is meticulous in details and perfectly replaces manual labor to realize the automated production of profile 100 and ensure the quality of finished products.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
