Description

Technical Field

[0001] The present application relates to the field of transmission equipment, and in particular to an intelligent suspension conveying system. Background Art

[0002] With the continuous development of automation technology, robots are increasingly being used to replace manual labor in loading and unloading or transporting materials in assembly lines in the surface treatment industry, logistics, machinery manufacturing and other industries.

[0003] In the hot rolling technology of plates, a suspension conveyor system is usually required to realize the loading and unloading and transportation of plates. The plates are hoisted by the suspension conveyor system, and then the suspension conveyor system drives the plates to the required loading or unloading position, and then the plates are separated from the suspension conveyor system, so as to facilitate the transportation of the plates.

[0004] However, when the suspension conveying system hoists two or more large plates (or other workpieces), the plates hoisted at the same time may collide with each other during the conveying process, causing damage to the plates. Summary of the invention

[0005] In order to reduce the occurrence of collisions between workpieces that are hoisted at the same time during the transportation process, the present application provides an intelligent suspension transportation system.

[0006] The intelligent suspension conveying system provided in this application adopts the following technical solution: An intelligent suspension conveying system comprises a fixed track, on which two or more conveying mechanisms are installed, each conveying mechanism comprises a roller that rolls with the track, a driving shaft is coaxially fixedly connected to the roller, an end of the driving shaft away from the roller is rotatably connected to a support plate, the bottom end of the support plate is fixedly connected to a mounting plate, each mounting plate is installed with a lifting mechanism for lifting workpieces, a driving motor is fixedly connected to the support plate in one of the conveying mechanisms, the driving motor is used to drive the driving shaft in the conveying mechanism to rotate, and a reciprocating mechanism for driving the two adjacent conveying mechanisms to move closer to or away from each other is installed between each two adjacent conveying mechanisms.

[0007] By adopting the above technical solution, the workpiece is hoisted by the corresponding hoisting mechanism under each mounting plate, and then the two adjacent conveying mechanisms are driven by the reciprocating mechanism to move in the direction of moving away from or approaching each other, until the workpieces hoisted by the adjacent conveying mechanisms do not collide with each other, and the distance between the adjacent conveying mechanisms is adjusted. Then the drive motor is started, and the drive motor drives the corresponding drive shaft and roller to rotate. The rotation of the roller drives the rollers in other conveying mechanisms to move along the track together, so as to facilitate the transportation of the workpiece. By adjusting the distance between adjacent conveying mechanisms by the reciprocating mechanism, the collision of the workpieces hoisted at the same time during the transportation process is reduced.

[0008] Preferably, the reciprocating mechanism includes a reciprocating motor fixedly connected to one of the support plates, a reciprocating screw penetrating the support plate and rotatably connected to the support plate is coaxially fixed on the output shaft of the reciprocating motor, and the reciprocating screw is threadedly connected to the adjacent support plate.

[0009] By adopting the above technical solution, the reciprocating motor is started, the reciprocating motor drives the reciprocating screw to rotate, and the rotation of the reciprocating screw drives the adjacent support plates to move, thereby adjusting the adjacent conveying mechanisms to move away from or towards each other.

[0010] The transmission gear is meshed with the driving gear of the driving gear, and the transmission gear meshes with the driving gear. A pair of fixed blocks are also fixedly connected to a side of the support plate on which the reciprocating motor is installed, and a transmission shaft is coaxially fixedly connected to the transmission shaft and a driving plate, and the transmission gear meshes with the transmission gear. A toggle lever is fixedly connected to the circumferential side of the driving plate, and the mounting plate is fixedly connected to the support frame, and a locking rod is vertically slidably connected to the support frame, and the upper end of the locking rod is fixedly connected to a locking block, and the upper end of the locking block is provided with a locking groove, and the rotation of the driving plate drives the toggle lever to toggle the locking rod to rise, so that the locking groove in the locking block is tightly engaged with the adjacent driving shaft.

[0011] By adopting the above technical solution, when the reciprocating motor is started, the reciprocating motor drives the reciprocating screw and the driving gear to rotate, the driving gear rotates to drive the transmission gear 1 and the transmission gear 2 to rotate, the transmission gear 2 rotates to drive the transmission shaft and the driving disk to rotate, and the driving disk rotates to drive the toggle rod to rotate. The rotation of the toggle rod toggle the locking rod and the locking block to rise, and the locking groove in the locking block is tightly engaged with the adjacent driving shaft, thereby locking the driving shaft and the corresponding roller. In the process of continuous rotation of the driving disk, the locking groove is always clamped with the driving shaft, that is, the locking between the conveying mechanism installed with the reciprocating motor and the track is completed, which is convenient for adjusting the distance between adjacent conveying mechanisms.

[0012] Preferably, the groove wall of the locking groove is provided with a plurality of elastic raised strips.

[0013] By adopting the above technical solution, the locking block can better limit the rotation of the driving shaft, thereby better quickly fixing the driving shaft and the roller.

[0014] Preferably, the diameters of the driving gear, transmission gear one and transmission gear two decrease sequentially.

[0015] By adopting the above technical solution, when the reciprocating screw drives the driving gear to rotate, the rotation of the driving gear can drive the driving plate to rotate rapidly through the transmission gear 1 and the transmission gear 2, thereby accelerating the driving plate and ensuring that during the rotation of the reciprocating screw, the driving plate can always be engaged with the driving shaft by toggling the locking block through the toggle rod.

[0016] Preferably, a guide rack having the same length as the track is fixedly connected to the track, and the roller is a guide gear meshing with the guide rack.

[0017] By adopting the above technical solution, when the roller rotates, the roller can move along the guide gear more smoothly.

[0018] Preferably, there are two tracks, and each of the conveying mechanisms includes two rollers, one roller corresponds to one track, and the roller and the track are in rolling cooperation.

[0019] By adopting the above technical solution, the same conveying mechanism cooperates with the track through two rollers in rolling manner, thereby ensuring that the conveying mechanism and the lifting mechanism can stably transport the workpiece.

[0020] Preferably, the locking rod is a counterweight rod.

[0021] By adopting the above technical solution, when the reciprocating motor stops rotating, the driving block stops rotating, and the toggle rod on the driving block is controlled to stop directly below the driving block, at which time the toggle rod is disengaged from the locking stem. The locking rod can be smoothly lowered by its own gravity, and the locking rod drives the locking block to disengage from the driving shaft, and the locking block releases the lock on the driving shaft.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The distance between adjacent conveying mechanisms is adjusted by the reciprocating mechanism, which reduces the collision of workpieces hoisted at the same time during the conveying process; 2. When adjusting the distance between adjacent conveying mechanisms, the conveying mechanism equipped with a reciprocating motor can achieve automatic locking with the track; 3.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0028] The present application embodiment discloses an intelligent suspension conveying system. Figure 1 and Figure 2 The intelligent suspension conveying system includes two tracks 1 fixed on the roof plate, and the two tracks 1 are arranged parallel to each other. Two or more conveying mechanisms 2 are installed on the track 1, and the embodiment of the present application includes two conveying mechanisms 2.

[0029] Each conveying mechanism 2 includes a roller 21 that rolls with each track 1, and each roller 21 is coaxially fixedly connected to a drive shaft 22. One end of each drive shaft 22 away from the roller 21 is rotatably connected to a support plate 23, and two support plates 23 in the same conveying mechanism 2 are commonly fixedly connected to the same mounting plate 24. A hoisting mechanism for hoisting workpieces is installed on each mounting plate 24.

[0030] In order to drive the conveying mechanism 2 to move along the track 1, a driving motor 25 is fixedly connected to each support plate 23 in one of the conveying mechanisms 2, and each driving motor 25 is used to drive a corresponding driving shaft 22 in the conveying mechanism 2 to rotate. In order to reduce the collision of workpieces hoisted at the same time during the conveying process, a reciprocating mechanism 3 is installed between each two adjacent conveying mechanisms 2 to drive the two adjacent conveying mechanisms 2 to move closer to or away from each other.

[0031] The inner bottom wall of each track 1 is fixedly connected with a guide rack 11, and the guide rack 11 is the same length as the track 1. The roller 21 is a guide gear 211 meshed with the guide rack 11 on the track 1. In this way, the roller 21 can move more smoothly along the guide rack 11 when rotating, further improving the movement stability of the conveying mechanism 2.

[0032] Reference Figure 1 and Figure 2 The reciprocating mechanism 3 includes a reciprocating motor 31 fixedly connected to each support plate 23 in one of the conveying mechanisms 2. A reciprocating screw 32 penetrating the support plate 23 and rotatably connected to the support plate 23 is coaxially fixed on the output shaft of each reciprocating motor 31, and the reciprocating screw 32 is threadedly connected to a support plate 23 of the adjacent conveying mechanism 2.

[0033] When the distance between adjacent conveying mechanisms 2 needs to be adjusted, two reciprocating motors 31 are started at the same time, and each reciprocating motor 31 drives the corresponding reciprocating screw 32 to rotate. Since each reciprocating screw 32 is threadedly connected to the support plate 23 on the adjacent conveying mechanism 2, the rotation of the reciprocating screw 32 can drive the adjacent support plate 23 and the corresponding conveying mechanism 2 to move toward or away from the reciprocating motor 31 until the workpieces hoisted on the adjacent conveying mechanisms 2 do not collide with each other.

[0034] Reference Figure 2 and Figure 3 In order to facilitate locking between the conveying mechanism 2 with the reciprocating motor 31 and the track 1, a locking mechanism 4 is installed on the conveying mechanism 2 with the reciprocating motor 31. A mounting groove 231 is provided on one side of each support plate 23 with the reciprocating motor 31 installed. A driving gear 41 arranged in the mounting groove 231 is coaxially fixedly connected to each reciprocating screw 32. A transmission gear 1 42 is rotatably connected in the mounting groove 231, and the transmission gear 1 42 is meshed with the driving gear 41. A pair of fixed blocks 43 are also fixedly connected to one side of the support plate 23 with the reciprocating motor 31 installed. A transmission shaft 44 is rotatably connected between the pair of fixed blocks 43, and a transmission gear 2 45 and a driving disk 46 are coaxially fixed on the transmission shaft 44, and the transmission gear 1 42 is meshed with the transmission gear 2 45.

[0035] A toggle rod 47 is fixedly connected to the peripheral side of the driving disk 46, and two support frames 5 are fixedly connected to the upper surface of one of the mounting plates 24. A locking rod 48 is vertically slidably connected to each support frame 5, and a locking block 49 is fixedly connected to the upper end of the locking rod 48. A locking groove 491 is provided on the upper surface of the locking block 49. When the driving disk 46 rotates, the driving disk 46 drives the toggle rod 47 to rotate, and the toggle rod 47 pushes the locking rod 48 and the locking block 49 to rise, so that the locking groove 491 in the locking block 49 is tightly engaged with the adjacent driving shaft 22, and the driving shaft 22 engaged with the locking groove 491 is locked. That is, the conveying mechanism 2 equipped with the reciprocating motor 31 is locked with the track 1, so that another conveying mechanism 2 can move relative to the conveying mechanism 2.

[0036] In order to facilitate the lifting and lowering of the locking rod 48, the locking rod 48 is a counterweight rod. When the reciprocating motor 31 stops rotating, the driving disk 46 also stops rotating. At this time, the toggle rod 47 will stay just below the driving disk 46 and no longer contact the locking rod 48. Since the locking rod 48 is a counterweight rod, the locking rod 48 is smoothly lowered by its own gravity, thereby driving the locking block 49 to separate from the driving shaft 22, thereby releasing the lock on the driving shaft 22.

[0037] In order to realize that the driving plate 46 can always engage with the driving shaft 22 by driving the locking block 49 through the toggle rod 47 during the process of the reciprocating screw 32 driving the driving gear 41 to rotate, the diameters of the driving gear 41, the transmission gear 1 42 and the transmission gear 2 45 are reduced in sequence. When the reciprocating screw 32 drives the driving gear 41 to rotate, since the driving gear 41, the transmission gear 1 42 and the transmission gear 2 45 are meshed in sequence and their diameters are reduced in sequence, the rotation of the driving gear 41 can drive the driving plate 46 to rotate quickly through the transmission gear 1 42 and the transmission gear 2 45, thereby accelerating the driving plate 46.

[0038] In order to ensure that the locking block 49 can better limit the rotation of the drive shaft 22, the groove wall of the locking groove 491 is provided with a plurality of elastic protrusion strips 6. The elastic protrusion strips 6 can increase the friction between the locking groove 491 and the drive shaft 22, thereby improving the locking effect of the locking block 49 on the drive shaft 22.

[0039] The implementation principle of the intelligent suspension conveying system of the embodiment of the present application is: according to the size of the workpiece to be hoisted, the distance between the two conveying mechanisms 2 is adjusted. One hoisting mechanism corresponds to one workpiece, and the workpiece is hoisted by the hoisting mechanism, and then the two driving motors 25 are started at the same time, and the driving motors 25 drive the rollers 21 to rotate. The two rollers 21 rotate at the same time to drive the conveying mechanism 2 and the other conveying mechanism 2 to move along the track 1, thereby completing the transportation of the workpiece.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
