In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
Fig. 1 to 5 are schematic views of a transmission structure according to an embodiment of the present invention.
Referring to fig. 1 and 2, fig. 1 is a front view of a transfer structure, and fig. 2 is a left view of the transfer structure, the transfer structure including a driving device 1 for releasing a wire 2 to be transferred and a traction device 3 for drawing the released wire 2.
In this embodiment, the conveying structure includes a driving device 1 and a carrying device 21, and the driving device 1 realizes the release of the wire 2 by driving the carrying device 21. Specifically, the wire 2 is wound around the bearing device 21, the bearing device 21 can rotate around the axis thereof, the driving device 1 includes a first rotating wheel 11 and a second rotating wheel 12, the first rotating wheel 11 is a driving wheel, the second rotating wheel 12 is a driven wheel, and the second rotating wheel 12 is engaged with the bearing device 21, so that when the first rotating wheel 11 rotates, the bearing device 21 engaged with the second rotating wheel 12 can correspondingly rotate around the axis thereof, and when the rotating direction of the bearing device 21 is the same as the winding direction of the wire 2, the wire 2 wound on the bearing device 21 can be released.
The shape and the carrying manner of the carrying device 21, the form and the material of the wire 2 can be adjusted according to actual needs without additional restrictions. For example, the carrier 21 may be cylindrical or flat, the wire 2 may surround the carrier 21 or be stacked on the surface of the carrier 21, the cross section of the wire 2 perpendicular to the conveying direction thereof may be circular, square, circular, etc., and the material of the wire 2 may be various materials such as steel, copper, aluminum, and alloys thereof.
In this embodiment, the traction device 3 includes a third rotating wheel 31, the third rotating wheel 31 is in close contact with the wire 2, and the third rotating wheel 31 can drive the wire 2 by rotating, so as to realize the transmission of the wire 2; furthermore, the traction device 3 further comprises a clamping device 32, and the clamping device 32 clamps the wire and moves to realize the transmission of the wire.
In this embodiment, the transmission structure includes a sliding groove 5 horizontally disposed, the step pulley 4 includes a movable pulley slidably disposed in the sliding groove 5, and the wire 2 is wound around the step pulley 4 from a first side of the step pulley 4; the segment difference wheel 4 is connected with a resetting device 6. In this embodiment, the resetting device 6 includes a suspended weight 61, a guide shaft 62 and a connecting cable 63, the step pulley 4 is connected to the weight 61 via the connecting cable 63, the weight 61 can move up and down along the guide shaft 62 penetrating the weight 61, and the weight 61 applies a pulling force toward the first side to the step pulley 4, so that the step pulley 4 can move toward the first side when the releasing speed is greater than the pulling speed and the wire 2 is loosened.
In the present embodiment, the level difference wheel 4 is movable according to the speed difference between the releasing speed and the pulling speed of the wire 2.
The specific moving mode is as follows:
when the releasing speed of the wire 2 is the same as the pulling speed, the length of the wire 2 on the conveying path between the bearing device 21 and the pulling device 3 is unchanged, the force exerted by the counterweight 61 on the segment difference wheel 4 enables the segment difference wheel 4 to tension the wire 2 on the conveying path, so that the wire 2 is always in a tensioned state, and meanwhile, the tension of the wire 2 on the segment difference wheel 4 on the conveying path is equal to the tension of the counterweight 61 on the segment difference wheel 4, so that the segment difference wheel 4 is in a balanced state. In this way, the wire 2 can be prevented from being stuck to other parts of the conveying structure or other structures adjacent to the conveying structure due to scattering.
Referring to fig. 3, when the wire 2 is released at a speed lower than the pulling speed, the length of the wire released per unit time is less than the length of the wire pulled out, and this missing length of wire needs to be compensated by the wire 2 between the carrier 21 and the pulling device 3. In this way, the wire 2 between the bearing device 21 and the traction device 3 is gradually shortened along with the advancement of time, and a larger pulling force is applied to the step pulley 4, at this time, the pulling force of the wire 2 on the conveying path to the step pulley 4 is larger than the pulling force of the counterweight 61 to the step pulley 4, and the step pulley 4 moves to one side (the moving direction is shown by an arrow a in the figure).
Referring to fig. 4, when the wire 2 is released at a speed greater than the drawing speed, the length of the wire released per unit time is greater than the length of the wire drawn out, and the excess wire 2 is temporarily left between the carrier 21 and the drawing device 3. Due to the fact that the wire 2 between the bearing device 21 and the traction device 3 is continuously increased, the pulling force of the wire 2 on the stepped wheel 4 on the conveying path is reduced, and the stepped wheel 4 moves towards the other side (the moving direction is shown by an arrow B in the drawing) under the pulling force of the balancing weight 61, so that the increased wire 2 is still in a tight state. In this embodiment, set up the sliding tray 5 that the level was placed for poor wheel 4 of section slides in the sliding tray, be favorable to avoiding poor wheel 4 of section to rock because of receiving the external factor influence, and then avoid poor wheel 4 of section to exert non-uniform stress to wire rod 2 when rocking and cause the wire rod performance to change, guarantee that the 2 performances of wire rod that convey was gone out are not influenced.
It should be noted that, in other embodiments, the resetting device may also be a spring connected to the segment difference wheel, and the resetting function is realized by the tensile force or pressure of the spring deformation; in addition, the slide groove 5 may be provided vertically, and the moving direction of the stepped pulley 4 may be vertical. When the moving direction of the segment difference wheel is vertical, a reset device is not arranged, and the reset effect is realized only by the gravity of the segment difference wheel.
It should be noted that, in the process of releasing the wire 2, a point separated from the carrier 21 is a wire releasing point, in this embodiment, the conveying device further includes a first limiting device 101, the first limiting device 101 is located on a side of a line connecting the releasing point of the wire 2 and the step pulley 4, the side being close to the sliding groove 5, and the first limiting device 101 is configured to receive the wire 2 released by the driving device 1 and transmit the wire 2 to the step pulley 4. So, be favorable to reducing the spatial position that wire rod 2 occupied, avoid wire rod 2 to touch other structures at the in-process that removes along with the poor wheel 4 removal of section, guarantee wire rod 2's safety. Referring to fig. 5, in the present embodiment, the sliding slot 5 includes an initial position 52, and a first position 51 and a second position 53 located at two opposite sides of the initial position 52, the sensing and controlling device 7 includes a controller 72 and a sensing module 71 located at the first position 51 and the second position 53, the controller 72 is connected to the sensing module 71, the sensing module 71 is used for sensing whether the stepped wheel 4 is located at its own position, and the controller 72 is used for controlling the driving device 1 and/or the traction device 3 according to a sensing result of the sensing module 71 to eliminate the speed difference.
For example, when the conveying structure is in a state of being just started, the segment difference wheel 4 is in the initial position 52, and the releasing speed and the drawing speed of the wire rod are the same; at a certain moment, the traction speed increases while the release speed is unchanged, so that the stepped pulley 4 moves to the first position 51; when the stepped difference wheel 4 moves to the first position 51, the sensing module 71 at the first position 51 reports sensing information to the controller 72 to represent that the stepped difference wheel 4 is sensed, and after receiving the sensing information, the controller 72 can judge that the traction speed of the stepped difference wheel 4 is greater than the release speed according to the position of the sensing module 71 which sends out the sensing information, and further, the controller 72 can reduce the traction speed and/or increase the release speed to eliminate the speed difference according to actual needs.
In this embodiment, the transmission structure further includes a power device 8 and a brake device 9, the brake device 9 is selectively locked on the surface of the first rotating wheel 11 of the driving device 1 or separated from the first rotating wheel 11 under the control of the power device 8, the power device 8 is respectively connected with the driving device 1, the traction device 3 and the brake device 9, and the power device 8 is used for controlling the brake device 9 to be separated from the first rotating wheel 11. In this way, when the power device 8 stops the wire transmission by no longer powering the driving device 1 and the traction device 3, the brake device 9 can automatically block and lock the first rotating wheel 11, thereby preventing the bearing device 21 from releasing the wire 2 due to slipping.
In this embodiment, the conveying device further includes a second limiting device 102, and the second limiting device 102 is located on a side of the first position 51 away from the initial position 52 and/or the second position 53 away from the initial position 52, and is located on a moving path of the step wheel 4. Thus, when the pulling speed and the releasing speed are different and the speed cannot be adjusted, or the wire 2 is accidentally broken, the second limiting device 102 can block the segment difference wheel 4 from further moving, and the segment difference wheel 4 is prevented from sliding out of the sliding groove 5.
In this embodiment, the controller 72 may eliminate the speed difference by a single speed adjustment. For example, the release speed and the traction speed each have two selectable speed parameters and the selectable speed parameters are the same, in particular, the release speed has both a first speed and a second speed and the traction speed also has both a first speed and a second speed. When the traction speed is higher than the release speed, the speed difference can be eliminated only by adjusting the traction speed down or the release speed up.
In this embodiment, the sensing and controlling device 7 further includes a timer 73, the timer 73 is connected to the controller 72 and the sensing module 71, and the timer 73 is used for recording a time length from the last sensing of the stepped difference wheel 4. That is, the sensing module 71 resets the timer 73 each time it detects the stepped wheel 4. As such, after the controller 72 eliminates the speed difference between the release speed and the pull speed, the release speed and/or the pull speed may be adjusted again to move the stepped pulley 4 toward the initial position 52 until between the first position 51 and the second position 53, such that subsequent movement states of the stepped pulley 4 may be indicative of the speed difference in the release speed and/or the pull speed.
Since the difference between the first speed and the second speed is determined and the distance between the first position 51 and the initial position 52 is determined, the time for moving from the first position 51 to the initial position 52 is determined, and the controller 72 may remove the speed difference after controlling the stepped difference wheel 4 to move for a preset time, so that the stepped difference wheel 4 is exactly at the initial position 52.
In this embodiment, the step wheel 4 whose moving state is affected by the speed difference between the pulling speed and the releasing speed is provided, so that the speed difference between the pulling speed and the releasing speed can be determined by sensing the moving state of the step wheel 4, and then the speed difference is eliminated by adjusting the pulling speed and/or the releasing speed, so as to realize automatic synchronization of the pulling speed and the releasing speed.
The present invention further provides a transmission structure, different from the previous embodiment, in this embodiment, the transmission structure further includes a counter for respectively counting the number of times that each sensing module senses the step wheel. As will be described in detail below with reference to fig. 6, fig. 6 is a schematic diagram of a transmission structure according to another embodiment of the present invention. The same or corresponding structure as that in the previous embodiment may be referred to the corresponding description of the previous embodiment, and will not be described in detail below.
In this embodiment, there is a time difference between the step pulley moving to the first position having the sensing module 271 and the controller 272 adjusting the pulling speed or the releasing speed, and within the time difference, the step pulley moves to a side of the first position away from the initial position. When the controller 272 adjusts the pulling speed or the releasing speed to return the stepped wheel to the initial position, the sensing module 271 at the first position senses the stepped wheel again, and the accumulated value of the sensing module 271 at the first position is 2, and the controller 272 is not required to adjust the speed. As can be seen from the above, when the integrated value of the sensing module 271 at a certain position is an even number, the controller 272 does not adjust the pulling speed or the releasing speed so that the stepped wheel can return to the initial position.
In this embodiment, by setting the counter 274, the speed adjustment of the controller 272 is prevented from being triggered in the process of returning to the initial position by the step pulley, which is beneficial to ensuring that the step pulley can return to the position between the first position and the second position, and further the sensing information of the sensing module 271 can effectively represent the speed difference between the traction speed and the release speed.
In another embodiment of the present invention, a transmission structure is further provided, different from the previous embodiment, in this embodiment, the sensing module includes a plurality of sensors sequentially arranged in the moving direction of the step wheel, and the selectable speed parameters of the pulling speed and the releasing speed have at least three types. As will be described in detail below with reference to fig. 7, fig. 7 is a schematic diagram of a transmission structure according to another embodiment of the present invention. The same or corresponding structure as that in the previous embodiment may be referred to the corresponding description of the previous embodiment, and will not be described in detail below.
In this embodiment, the selectable speed parameters of the pulling speed and the releasing speed are the same and have at least three, and there is no time difference between the step wheel 34 moving to a certain sensor and the controller adjusting the pulling speed and/or the releasing speed.
For example, one side of the initial position 352 has sensors at a first position 354, a second position 355, and a third position 356, and the controller first adjusts the pull speed and/or release speed when the sensor 371 at the first position 354 senses the stepped wheel 34.
If the first speed adjustment has eliminated the speed difference, the step wheel 34 is at the first position 354, and the sensor 371 at the first position 354 continuously reports the information of sensing the step wheel 34. Thus, when the duration recorded by the timer is equal to the time interval between two adjacent times of reporting the sensing information by the sensor 371 before being reset, the speed difference can be considered to have been eliminated. At this point, the controller may again make speed adjustments to return the stepped wheels 34 to the initial position.
If the speed difference is not eliminated in the first time of speed adjustment, the step difference wheel 34 continues to move to the second position 355, the sensor 371 at the second position 355 reports the information of sensing the step difference wheel 34, and the controller reduces the traction speed and/or increases the release speed for the second time; if the second speed adjustment has eliminated the speed differential, the controller may again make the speed adjustment to return the stepped wheel 34 to the initial position 352.
In returning to the initial position 352, when the step difference wheel 34 passes the second position 355, the sensor 371 of the second position 355 senses the step difference wheel 34 for an even number of times, and the controller does not perform the speed adjustment operation; after the stepped wheel 34 passes the first position 354, the controller makes a speed adjustment again to remove the speed difference according to the duration recorded by the timer, so that the stepped wheel 34 stays at the initial position 352.
In this embodiment, the sensing module includes a plurality of sensors in the moving direction of the step wheel 34 to realize a plurality of times of sensing and corresponding speed adjustment, thereby enabling the pulling speed and the releasing speed to be automatically synchronized.
Correspondingly, the embodiment of the invention also provides a transmission system, which comprises the transmission structure.
In this embodiment, the wire rod pulling speed and the releasing speed of the conveying system can be automatically synchronized, and the degree of automation is high.
