Description

Technical Field

[0001] The utility model relates to the technical field of blank position adjustment, and more specifically, to a blank center position adjustment device. Background Art

[0002] The bathroom industry has flourished with the improvement of people's living standards. Current common bathroom products include smart toilets, bathtubs, squat toilets, etc. Squat toilets are popular among consumers because of their low price, quality and good flushing effect.

[0003] In the manufacturing process of squat toilets, there is a blank trimming step, which is generally carried out in the factory. After the blank is trimmed, it is generally necessary to transport the blank over a long distance and place it on a shelf. In order to save manpower and improve work efficiency, it is necessary to produce equipment that can transport the blank over a long distance and move it to the shelf. When the equipment is transported over a long distance, since it is a manual operation to move the blank to the transportation line after trimming, there will be many cases of incorrect placement of the blank, which makes it very inconvenient for other devices to take and place the blank later.

[0004] In order to make it more convenient for other devices behind to carry the blank, designing an adjustment device that can adjust the center position of the blank has become an urgent problem to be solved. Summary of the invention

[0005] In view of the existing technical problems, the purpose of the utility model is to provide a device for adjusting the center position of the blank, which adjusts the position of the center of the blank on the transport platform through the cooperation of the transport platform, the double-acting cylinder and the compression plate, thereby facilitating the subsequent removal and placement of the blank.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A device for adjusting the center position of a blank comprises a transport platform, the transport platform comprises a frame, a conveyor chain for conveying the blanks is arranged on the frame, a horizontally placed double-acting cylinder is fixedly connected to the frame, the double-acting cylinder comprises a cylinder body, a piston rod is inserted into the cylinder body, a first compression plate is fixedly connected to one end of the piston rod away from the cylinder body, the first compression plate is connected to a synchronous connecting rod, one end of the synchronous connecting rod is connected to the first compression plate, and the other end is connected to a second compression plate, the first compression plate and the second compression plate are parallel to and opposite to each other, the first compression plate and the second compression plate are respectively located on both sides of the blank conveyed by the conveyor chain, and the distance from the plate surface of the first compression plate to the center conveying line of the transport platform is equal to the distance from the plate surface of the second compression plate to the center conveying line of the transport platform.

[0008] By adopting the above technical solution: at the beginning, the piston rod extends out of the cylinder body, so that the first compression plate is away from the transport platform. When the first compression plate is away from the transport platform, under the action of the synchronous connecting rod, the second compression plate will also move away from the transport platform with the first compression plate. A larger space is left between the first compression plate and the second compression plate for the blank conveyed by the conveying chain to pass through. When the blank is transported to the first compression plate by the conveying chain, the piston rod contracts into the cylinder body, so that the first compression plate approaches the transport platform. When the first compression plate approaches the transport platform, under the action of the synchronous connecting rod, the second compression plate will also move closer to the transport platform with the first compression plate. Under the simultaneous pushing action of the first compression plate and the second compression plate, the blank moves closer to the central transport line of the transport platform until the center of the blank is on the central transport line of the transport platform. Then the piston rod extends out of the cylinder body again, so that the first compression plate and the second compression plate are both away from the transport platform, and the first compression plate and the second compression plate return to their initial states.

[0009] Furthermore, a first elastic rubber pad is fixedly connected to a surface of the first compression plate facing the transport platform.

[0010] By adopting the above technical solution: the provision of the first elastic rubber pad makes it less likely for the first compression plate to cause contact damage when pushing the blank to move closer to the central transport line of the transport platform.

[0011] Furthermore, a second elastic rubber pad is fixedly connected to a side of the second compression plate facing the transport platform.

[0012] By adopting the above technical solution: the provision of the second elastic rubber pad makes it less likely for the second compression plate to cause contact damage when pushing the blank to move closer to the central transport line of the transport platform.

[0013] Furthermore, a first horizontal rod is arranged between the first compression plate and the piston rod, a plurality of vertical rods are fixedly connected to a side of the first horizontal rod away from the piston rod, the vertical rods are fixedly connected to the first compression plate, and the first horizontal rod is fixedly connected to an end of the piston rod away from the cylinder body.

[0014] By adopting the above technical solution: the first horizontal rod is fixedly connected to the piston rod and the vertical rod at the same time, and the vertical rod is fixedly connected to the first compression plate, so that the first compression plate and the piston rod are indirectly fixedly connected, and the first compression plate and the synchronous connecting rod are indirectly connected through the first horizontal rod and the vertical rod. At the same time, since the first compression plate and the piston rod and the synchronous connecting rod are separated by the first horizontal rod and the vertical rod, the distance between the first compression plate and the piston rod and the synchronous connecting rod is pulled apart, so that the piston rod and the synchronous connecting rod can be arranged below the table surface of the transport platform, and the first compression plate and the second compression plate can be arranged above the table surface of the transport platform, and the position where the first compression plate and the second compression plate are close to each other is staggered with the position of the double-acting cylinder, so that when the center position adjustment device of the blank is used on the transport platform, the overall space is more reasonable.

[0015] Furthermore, a second horizontal rod is fixedly connected to the frame, a slide rail is fixedly connected to the upper side of the second horizontal rod, the slide rail is parallel to the double-acting cylinder, and a sliding block is fixedly connected to the lower side of the first horizontal rod, the slide rail cooperates with the sliding block.

[0016] By adopting the above technical solution: since the sliding block cooperates with the sliding rail, and the sliding rail is parallel to the double-acting cylinder, and the sliding block is fixedly connected to the first horizontal rod, when the piston rod of the double-acting cylinder is extended or retracted, it will be restricted by the sliding rail and the sliding block, and the movement trajectory of the piston rod is stable, thereby improving the stability of the equipment.

[0017] Furthermore, the double-acting cylinder is connected to a solenoid valve, and the solenoid valve is electrically connected to a PLC controller.

[0018] By adopting the above technical solution, the solenoid valve is used to control the air intake and exhaust of the double-acting cylinder, thereby controlling the extension and contraction of the piston rod, and the PLC controller controls the solenoid valve, so automatic operation can be achieved by setting the program on the PLC controller to automatically control the extension and contraction of the double-acting cylinder.

[0019] Furthermore, a photoelectric sensor is provided on the frame, and the photoelectric sensor is used to sense whether there is a blank at the place where the first compression plate and the second compression plate are close to each other, and the photoelectric sensor is electrically connected to the PLC controller.

[0020] By adopting the above technical solution: when the photoelectric sensor senses that there is a blank where the first compression plate and the second compression plate are close to each other, a signal indicating the presence of the blank is sent to the PLC controller, and the PLC controller controls the extension and contraction of the piston rod by controlling the solenoid valve.

[0021] Furthermore, a blocking column is fixedly connected to the transport platform surface for blocking the blank at the position where the first compression plate and the second compression plate are close to each other from continuing to move forward.

[0022] When the blank is transported by the conveyor chain to the place where the first compression plate and the second compression plate are close to each other, if the transport platform is not closed, the conveyor chain will continue to transport the blank forward, so that when the first compression plate and the second compression plate are close to each other, the blank is no longer at the first compression plate, resulting in failure to adjust the center position of the blank. By adopting the above-mentioned technical solution: the setting of the blocking column, even if the transport platform is not closed, the blank at the place where the first compression plate and the second compression plate are close to each other will not continue to move forward, until the first compression plate and the second compression plate have adjusted the center position of the blank, and then other blank-taking and transportation equipment is used to lift away the blank with the adjusted center position.

[0023] Further, the synchronous connecting rod includes a third horizontal rod fixed to the frame, a vertically placed first column is fixed to the upper side of the third horizontal rod, a fourth horizontal rod is arranged at the first column, the center of the fourth horizontal rod is rotatably connected to the first column, one end of the fourth horizontal rod is fixed to a vertically placed second column, and the other end is fixed to a vertically placed third column, the second column is connected to a fifth horizontal rod, one end of the fifth horizontal rod is rotatably connected to the second column, and the other end is rotatably connected to the first compression plate, the third column is connected to a sixth horizontal rod, one end of the sixth horizontal rod is rotatably connected to the third column, and the other end is rotatably connected to the second compression plate.

[0024] By adopting the above technical solution: when the piston rod extends and pushes the first compression plate to move in a direction away from the transport platform, the movement of the first compression plate will cause the fifth horizontal rod to rotate, and the rotation of the fifth horizontal rod will cause the fourth horizontal rod to rotate, and the rotation of the fourth horizontal rod will cause the sixth horizontal rod to rotate, and the rotation of the sixth horizontal rod will push the second compression plate to move synchronously in a direction away from the transport platform. When the piston rod contracts and pulls the first compression plate to move in a direction close to the transport platform, the movement of the first compression plate will cause the fifth horizontal rod to rotate in another direction, and then cause the fourth horizontal rod and the sixth horizontal rod to rotate accordingly, thereby pulling the second compression plate to move synchronously in a direction close to the transport platform.

[0025] Compared with the prior art, the beneficial effects of the utility model are: 1. Through the cooperation of the transport platform, double-acting cylinder, synchronous connecting rod and compression plate, the position of the center of the blank on the transport platform is adjusted, so as to facilitate the later placement of the blank; 2. Through the cooperation of the slide rail and the sliding block, the direction of contraction and extension of the piston rod is more stable; 3. The setting of the elastic rubber pad makes it difficult to cause contact damage when adjusting the center position of the blank. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] See also Figures 1 to 4 As shown, a device for adjusting the center position of a blank comprises a transport platform 1, the transport platform 1 comprises a frame 2, a conveying chain 3 is arranged on the frame 2, a horizontally placed double-acting cylinder 4 is fixedly connected to the frame 2, the double-acting cylinder 4 is connected to a solenoid valve 15, and the solenoid valve 15 is electrically connected to a PLC controller 16. The double-acting cylinder 4 comprises a cylinder body 41, a piston rod 42 is inserted into the cylinder body, a first compression plate 5 is fixedly connected to one end of the piston rod 42 away from the cylinder body 41, the piston rod 42 and the first compression plate 5 are fixedly connected through a first horizontal rod 10 and a vertical rod 11, that is, a first horizontal rod 10 is arranged between the first compression plate 5 and the piston rod 42, two vertical rods 11 are welded to the side of the first horizontal rod 10 away from the piston rod 42, the vertical rod 11 is welded to the first compression plate 5, and the first horizontal rod 10 is screwed to one end of the piston rod 42 away from the cylinder body 41. The first compression plate 5 is also connected to a synchronous connecting rod 7, and the first compression plate 5 and the synchronous connecting rod 7 are connected through a first horizontal rod 10, that is, two vertical rods 11 are welded to the side of the first horizontal rod 10 away from the piston rod 42, and the vertical rods 11 are welded to the first compression plate 5. In addition to one end of the synchronous connecting rod 7 being connected to the first compression plate 5, the other end of the synchronous connecting rod 7 is also connected to the second compression plate 6. The connection method of the synchronous connecting rod 7 and the second compression plate 6 can refer to the connection method of the synchronous connecting rod 7 and the first compression plate 5, and the first compression plate 5 and the second compression plate 6 are parallel to each other and face each other. The first compression plate 5 and the second compression plate 6 are respectively located on both sides of the blank conveyed by the conveyor chain 3. The plate surface of the first compression plate 5 and the plate surface of the second compression plate 6 are parallel to the central transportation line of the transport platform 1, and the distance from the plate surface of the first compression plate 5 to the central transportation line of the transport platform 1 is equal to the distance from the plate surface of the second compression plate 6 to the central transportation line of the transport platform 1.

[0039] For more intelligent operation, a photoelectric sensor 17 is also provided on the frame 2 , and the photoelectric sensor 17 is used to sense whether there is a blank where the first compression plate 5 and the second compression plate 6 are close to each other. The photoelectric sensor 17 is electrically connected to the PLC controller 16 .

[0040] In order to make the position of the blank relatively stable when adjusting the center position of the blank, a blocking column 18 can be fixed to the frame 2, and the blocking column 18 is used to stop the blank at the position where the first compression plate 5 and the second compression plate 6 are close to each other from continuing to move forward.

[0041] When there is no blank at the position where the first compression plate 5 and the second compression plate 6 are close to each other, the piston rod 42 is in a state of extending out of the cylinder body 41. At this time, the first compression plate 5 is far away from the transport platform 1. When the first compression plate 5 is far away from the transport platform 1, due to the action of the synchronous connecting rod 7, the second compression plate 6 is also in a state of being far away from the transport platform 1. A large space is left between the first compression plate 5 and the second compression plate 6 for the blank transported by the conveying chain 3 to pass through. When the blank is transported to the first compression plate 5 by the conveying chain 3, the blank is blocked by the blocking column 18. Before the first compression plate 5 and the second compression plate 6 are brought close to each other to adjust the center position of the blank, the position of the blank is relatively stable. At the same time, the photoelectric sensor 17 senses the presence of the blank, so the photoelectric sensor 17 transmits the signal of the presence of the blank to the PLC controller 16. After receiving the signal, the PLC controller 16 controls the opening and closing of each channel of the solenoid valve 15, thereby controlling the inflow and outflow of gas in the cylinder 41, so that the piston rod 42 contracts into the cylinder 41, so that the first compression plate 5 approaches the transport platform 1. When the first compression plate 5 approaches the transport platform 1, under the action of the synchronous connecting rod 7, the second compression plate 6 will also approach the transport platform 1 along with the first compression plate 5. Under the simultaneous pushing action of the first compression plate 5 and the second compression plate 6, the blank moves closer to the central transport line of the transport platform 1 until the center of the blank is on the central transport line of the transport platform 1. Then, the PLC controller 16 controls the opening and closing of each channel of the solenoid valve 15 again, so that the piston rod 42 extends out of the cylinder body 41. Under the action of the synchronous connecting rod 7, the first compression plate 5 and the second compression plate 6 move away from the transport platform 1 synchronously, and the initial state of the first compression plate 5 and the second compression plate 6 is restored. Finally, the blank with the center position adjusted will be lifted away by other blank removal and transportation equipment.

[0042] See also Figure 1 , Figure 2 As shown, in order to prevent the first compression plate 5 and the second compression plate 6 from causing contact damage when they touch the blank or the tooling plate below the blank, a first elastic rubber pad 8 is bonded to the side of the first compression plate 5 facing the transport platform 1, and a second elastic rubber pad 9 is bonded to the side of the second compression plate 6 facing the transport platform 1.

[0043] See also Figure 3 , Figure 4As shown, in order to make the trajectory of extension and contraction of the piston rod 42 more stable, a second horizontal rod 12 is fixedly connected to the frame 2, a slide rail 13 is fixedly connected to the upper side of the second horizontal rod 12, the slide rail 13 is parallel to the double-acting cylinder 4, and a sliding block 14 is fixedly connected to the lower side of the first horizontal rod 10, and the slide rail 13 cooperates with the sliding block 14.

[0044] When the piston rod 42 is extended, the first horizontal rod 10 screwed to the piston rod 42 will move away from the transport platform 1. Since the sliding block 14 fixed to the lower side of the first horizontal rod 10 cooperates with the slide rail 13, the sliding block 14 can only move along the slide rail 13, thereby limiting the piston rod 42 to only make linear motion in the length direction of the double-acting cylinder 4, and the movement direction of the piston rod 42 is relatively stable.

[0045] See also Figure 5 , Figure 6 As shown, the synchronous connecting rod 7 includes a third horizontal rod 71 fixed to the bracket, a vertically placed first column 72 is fixed to the upper side of the third horizontal rod 71, a fourth horizontal rod 73 is arranged at the first column 72, and the center of the fourth horizontal rod 73 is rotatably connected to the first column 72, one end of the fourth horizontal rod 73 is fixed to a vertically placed second column 74, and the other end is fixed to a vertically placed third column 75, the second column 74 is connected to a fifth horizontal rod 76, one end of the fifth horizontal rod 76 is rotatably connected to the second column 74, and the other end is rotatably connected to the first compression plate 5, the third column 75 is connected to a sixth horizontal rod 77, one end of the sixth horizontal rod 77 is rotatably connected to the third column 75, and the other end is rotatably connected to the second compression plate 6.

[0046] When the piston rod 42 extends and pushes the first compression plate 5 to move in a direction away from the transport platform 1, the movement of the first compression plate 5 will cause the fifth horizontal rod 76 to rotate, and the rotation of the fifth horizontal rod 76 will cause the fourth horizontal rod 73 to rotate, and the rotation of the fourth horizontal rod 73 will cause the sixth horizontal rod 77 to rotate, and the rotation of the sixth horizontal rod 77 will push the second compression plate 6 to move synchronously in a direction away from the transport platform 1. When the piston rod 42 contracts and pulls the first compression plate 5 to move in a direction close to the transport platform 1, the movement of the first compression plate 5 will cause the fifth horizontal rod 76 to rotate in another direction, thereby causing the fourth horizontal rod 73 and the sixth horizontal rod 77 to rotate accordingly, thereby pulling the second compression plate 6 to move synchronously in a direction close to the transport platform 1.
