With the improvement of mechanical automation technology, the conveying modes between equipment and a rack body through a material pushing mechanism are increasing day by day. Theoretically, pushing equipment can realize the distance detection through setting up range sensor, but range sensor has with high costs, and occupation space is big, and detection range is limited, the relatively poor scheduling problem of commonality. In the prior art, the pushing mechanism induces the position state information of the moving part by arranging the sensor at the moving end, wires are inevitably required to be arranged at the moving end, and the wires are arranged at the moving end, so that the cost is increased, the installation time is prolonged, and the interference to the movement of the device is also caused.
As shown in fig. 1, in order to solve the above problem, the present embodiment provides a pushing mechanism. The pushing mechanism comprises a mounting frame 100, a sensing assembly 200, a driving assembly 300, a moving assembly 400 and a pushing member 500. Wherein, the sensing assembly 200 includes two signal sensing pieces 210, along pushing away the material direction, two signal sensing pieces 210 are coaxial setting respectively at the both ends of mounting bracket 100, and can send the preset signal when the light beam that two signal sensing pieces 210 sent communicates, drive assembly 300 sets up on mounting bracket 100, motion assembly 400 sets up the output at drive assembly 300, drive assembly 300 is used for driving motion assembly 400 along pushing away material direction reciprocating motion, it sets up on motion assembly 400 to push away material 500, after motion assembly 400 moved the extreme position who pushes away the material direction, it can the motion assembly 400 motion of drive to push away material 500 so that the light beam that two signal sensing pieces 210 sent communicate. Specifically, the preset signal is a signal indicating that the pushing mechanism reaches the limit position.
The pushing mechanism only enables the light beams of the two signal sensing pieces 210 to be communicated through the reaction force of the pushing piece 500, so that the pushing mechanism can be sent to reach the limit position, and corresponding operation is facilitated. This pushing equipment avoids laying the inductor moving the end, and the effectual drawback of avoiding the above-mentioned inductor of laying moving the end still reduces installation space, saves wiring cost and time except avoiding the wiring to the interference that the device motion caused at the moving terminal pair, and this device simple structure, small and exquisite convenient, easily installation. Meanwhile, the pushing mechanism has no blind area of detection range, which is beneficial to expanding the detection range, further expanding the application range and improving the universality. Therefore, compared with the conventional distance measuring sensor and the conventional wiring belt sensor, the sensing assembly of the pushing mechanism has the advantages of low cost and small space, the detection range of the pushing mechanism is large, a detection blind area does not exist, and the universality of the pushing structure is favorably improved. Illustratively, pusher 500 contacts the product to participate in the pushing of the product.
Illustratively, the sensing component 200 is preferably a coaxial optical fiber sensor, and the structure is sensitive to sensing, and can meet the structural requirements of the present embodiment, and simplify the structure of the pushing mechanism.
As shown in fig. 1, specifically, the mounting bracket 100 includes a first support plate 110, a second support plate 120, and a mounting seat 130. The first support plate 110 and the second support plate 120 are disposed at two ends of the mounting seat 130 to form a stable support structure, so that the pushing mechanism can stably push materials and bear other structures. It can be understood that the two signal sensing parts 210 are respectively disposed on the first support plate 110 and the second support plate 120, and the two signal sensing parts 210 are disposed at corresponding positions, so that the light beams emitted by the two signal sensing parts 210 can emit sensing signals when they are communicated.
With continued reference to fig. 1, in particular, the driving assembly 300 includes a cylinder body 310, a stainless steel tube 320, and an end cap 330. The stainless steel tube 320 extends along the pushing direction and is disposed on the mounting block 100, the cylinder body 310 is sleeved on the stainless steel tube 320, and the end caps 330 are disposed at two ends of the stainless steel tube 320 and are connected to the mounting block 100. Illustratively, the driving assembly 300 may be a magnetic coupling cylinder, which is simple and easy for the operator to assemble and maintain.
As shown in fig. 1, the moving assembly 400 may alternatively include a first moving member 410 and a second moving member 420. The first moving member 410 is connected to the output end of the driving assembly 300, the second moving member 420 is disposed on the first moving member 410, and the pushing member 500 is disposed on the second moving member 420. The driving assembly 300 drives the first moving part 410 and the second moving part 420 to move, so that the pushing part 500 is driven to move for feeding, the structure is simple, and the assembly and maintenance are convenient.
With continued reference to fig. 1-4, optionally, the motion assembly 400 further includes a light-transmitting rod 430 and a closure 440. The light-transmitting rod 430 is arranged on the second moving part 420 along the material pushing direction, the light-transmitting rod 430 is of a hollow structure, the first moving part 410 is provided with the extending hole 412, the closing part 440 can close the extending hole 412, the closing part 440 is provided with the light-transmitting hole, the reaction force of the material pushing part 500 can drive the second moving part 420 to move towards the first moving part 410, the light-transmitting rod 430 can penetrate through the light-transmitting hole, no external force is applied, the light-transmitting hole is in a closed state, and light beams emitted by the two signal sensing parts 210 can penetrate through the center of the light-transmitting rod 430 and communicate with each other, so that corresponding signals can be emitted. This simple structure avoids laying the inductor at the removal end, and the effectual drawback of avoiding the above-mentioned inductor of laying at the removal end, except avoiding the wiring to the interference that the device motion caused at the removal end, still reduces installation space, saves wiring cost and time. Illustratively, the closure member 440 is preferably made of a highly elastic material so as to achieve a closed state of the light-transmitting hole without external force, and the light-transmitting hole can be opened by external force.
Referring to fig. 1, in operation, the cylinder body 310 drives the first moving member 410 to move along the material pushing direction, and drives the second moving member 420 to push the material pushing member 500 to move. When the pushing member 500 pushes the material to the limit position, the pushing member 500 cannot move continuously, that is, the pushing member 500 and the second moving member 420 cannot move continuously along the pushing direction, so that the material is not stopped, but the first moving member 410 is connected to the cylinder body 310, and the cylinder body 310 still drives the first moving member 410 to move continuously along the axial direction of the first guiding shaft 451, so that the second moving member 420 is not moved, and the first moving member 410 moves continuously, so that the distance between the first moving member 410 and the second moving member 420 is reduced. Since the light-transmitting rod 430 is fixed on the movable member, the distance between the second movable member 420 and the first movable member 410 decreases, and the end of the light-transmitting rod 430 facing the first movable member 410 contacts the high-elasticity sealing member 440, and as the distance between the first movable member 410 and the second movable member 420 decreases, the light-transmitting rod 430 deforms the sealing member 440, and the light-transmitting hole in the sealing member 440 deforms to become larger. After the light hole is enlarged, the optical fiber bundle sent by the coaxially arranged signal sensing piece 210 can sense an optical fiber signal, so that the pushing mechanism is sensed to reach the pushing termination position, and the device can be judged to complete pushing.
With continued reference to fig. 1, further, the position of the light-transmitting rod 430 along the material pushing direction is adjustable, that is, the position of the light-transmitting rod 430 disposed on the second moving member 420 is adjustable. The material jamming and material sensing sensitivity is controlled by adjusting the position of the light-transmitting rod 430. That is, the closer the light-transmitting rod 430 is to the first moving member 410, the smaller the distance between the second moving member 420 and the first moving member 410 is, the light-transmitting rod 430 can touch and deform the closing member 440, so that the coaxially disposed signal sensing member 210 senses the optical fiber signal, thereby determining that the relative position between the pushing member 500 and the first moving member 410 is changed.
Referring to fig. 1 to 4, the moving assembly 400 further includes a first guiding element 450, and the first guiding element 450 is used for providing guidance for the moving assembly 400 to move along the material pushing direction, so as to improve the moving accuracy of the moving assembly 400. Specifically, the first guide 450 includes a first guide shaft 451 and a first bearing 452. The first guide shaft 451 passes through the first moving part 410 and the second moving part 420 along the pushing direction, and two ends of the first guide part 450 are disposed on the mounting block 100, so as to provide guidance for the movement of the moving assembly 400, ensure the smoothness of the moving process of the moving assembly 400, and avoid the occurrence of jamming. One of the first bearings 452 is disposed between the first guide shaft 451 and the first moving member 410, and the other first bearing 452 is disposed between the first guide shaft 451 and the second moving member 420, so that friction between the first moving member 410 and the second moving member 420 and the first guide shaft 451 is reduced, which is beneficial to ensuring the service life of the first moving member 410, the second moving member 420 and the first guide shaft 451, and improving the movement accuracy of the movement assembly 400.
As shown in fig. 2 to 4, the moving assembly 400 further includes a first connecting element 460, the first connecting element 460 is disposed along the pushing direction, the first connecting element 460 is configured to connect the first moving element 410 and the second moving element 420, and the relative positions of the first moving element 410 and the second moving element 420 are adjustable, that is, the connection between the first moving element 410 and the second moving element 420 is achieved, and the relative movement between the second moving element 420 and the first moving element 410 is also ensured.
Referring to fig. 2 to 4, the first connecting member 460 includes a sliding portion 461, a fixing portion 462, and a first limiting portion 463, a through hole 411 is formed on the first moving member 410, the sliding portion 461 passes through the through hole 411, and the first moving member 410 is connected in a sliding manner; the fixing portion 462 is connected to one end of the sliding portion 461, the fixing portion 462 is fixedly connected to the second moving member 420, the first limiting portion 463 is disposed at one end of the sliding portion 461 close to the fixing portion 462, the first limiting portion 463 abuts against the second moving member 420, and when the second moving member 420 moves towards the first moving member 410, the first limiting portion 463 can abut against the second moving member 420, so that the second moving member 420 can push the sliding portion 461 to slide in the through hole 411, and further the second moving member 420 approaches the first moving member 410. In order to prevent the first connecting element 460 from being separated from the through hole 411, the first connecting element 460 further includes a second limiting portion 464, the second limiting portion 464 is disposed at an end of the sliding portion 461 away from the first limiting portion 463, and the second limiting portion 464 can abut against the first moving element 410, so that the second limiting portion 464 can restrict a maximum distance between the second moving element 420 and the first moving element 410, and the first connecting element 460 is prevented from being separated from the through hole 411.
Illustratively, the first connecting member 460 can be a short-head shoulder bolt, which is a finished structure and is convenient to purchase, and the cost increase caused by separate processing is avoided.
As shown in fig. 1 to 4, the moving assembly 400 further includes a reset member 470, the reset member 470 is sleeved on the first connecting member 460, and the reset member 470 is disposed between the first moving member 410 and the second moving member 420, so as to provide a buffer for the relative movement between the second moving member 420 and the first moving member 410, and ensure that the material is pushed to the stop position without rigid collision with the material, thereby damaging the material. And when the distance between the first moving element 410 and the second moving element 420 decreases, the resetting element 470 can drive the second moving element 420 to move away from the first moving element 410, so as to reset the second moving element 420. Illustratively, the return member 470 is preferably a spring, which is of conventional construction, readily available and inexpensive to purchase.
With continued reference to fig. 1 and 2, the moving assembly 400 further includes a second guiding element 480, and the second guiding element 480 is used for guiding the second moving element 420 to move along the material pushing direction, which is beneficial to improving the precision of the movement of the second moving element 420. Specifically, the second guide 480 includes a second guide shaft 481 arranged along the pushing direction, one end of the second guide shaft 481 is slidably connected to the second moving member 420, and the other end is fixedly connected to the first moving member 410, so as to ensure the smoothness of the moving process of the second moving member 420 and avoid the occurrence of jamming.
As shown in fig. 2, further, the second guide 480 further includes a second bearing 482, and the second bearing 482 is disposed between the second guide shaft 481 and the second moving member 420, so that friction between the second moving member 420 and the second guide shaft 481 is reduced, which is advantageous in ensuring the service life of the second moving member 420 and the second guide shaft 481 and in improving the movement accuracy of the second moving member 420.
As an alternative, with continued reference to fig. 2, the pushing mechanism further includes two proximity sensors 600, the two proximity sensors 600 are respectively disposed on the mounting frame 100, and the two proximity sensors 600 can respectively detect two limit positions of the moving assembly 400.
Meanwhile, in the axial movement process of the cylinder body 310 along the stainless steel tube 320, if the material is not pushed to the end position, but the pushing member 500 cannot push the material continuously, the material jamming condition occurs. At this time, the pushing mechanism is in a moving state that the pushing element 500 and the second moving element 420 cannot move continuously along the first guide shaft 451 and are not stopped, but the first moving element 410 is connected to the cylinder body 310, and the cylinder body 310 still drives the first moving element 410 to move continuously along the axial direction of the first guide shaft 451, so that the second moving element 420 is not moved, and the first moving element 410 moves continuously, resulting in a decrease in the distance between the first moving element 410 and the second moving element 420. Since the light-transmitting rod 430 is fixed on the second moving member 420, the distance between the second moving member 420 and the first moving member 410 decreases, and the end of the light-transmitting rod 430 facing the first moving member 410 contacts the sealing member 440, and as the distance between the second moving member 420 and the first moving member 410 decreases, the light-transmitting rod 430 deforms the sealing member 440, and the light-transmitting hole in the sealing member 440 deforms and becomes larger. The optical fiber bundle sent by the coaxially arranged signal sensing element 210 can pass through after the light hole is enlarged, the coaxially arranged signal sensing element 210 can sense an optical fiber signal, and the left side approaching sensing element 600 does not sense that the moving assembly 400 reaches the pushing termination position, so that the device can be judged to have a material blocking condition, and an automatic alarm can be given.
It can be understood that, if the signal sensing element 210 and the proximity sensing element 600 both sense signals, the material pushing mechanism is in a material pushing completion state; if the signal sensing member 210 senses a signal, the approaching sensing member 600 does not sense the signal, and the material pushing mechanism is in a material clamping state; if the signal sensing piece 210 and the approaching sensing piece 600 cannot sense the signal, the material pushing mechanism is in a material pushing in-process state. In summary, the mechanism can determine the state of the mechanism according to the signals of the signal sensor 210 and the proximity sensor 600.
The specific working process of this embodiment is as follows:
first, the cylinder body 310 drives the first moving member 410 to move in the material pushing direction, and drives the second moving member 420 to push the material pushing member 500 to move. When the pushing member 500 pushes the material to the limit position, the pushing member 500 cannot move continuously, that is, the pushing member 500 and the second moving member 420 cannot move continuously along the pushing direction, so that the material is not stopped, but the first moving member 410 is connected with the cylinder body 310, and the cylinder body 310 still drives the moving member to move continuously along the axial direction of the first guiding shaft 451, so that the first moving member 410 moves continuously, and the second moving member 420 does not move, so that the distance between the first moving member 410 and the second moving member 420 is reduced. Since the light-transmitting rod 430 is fixed on the movable member, the distance between the second movable member 420 and the first movable member 410 decreases, and the end of the light-transmitting rod 430 facing the first movable member 410 contacts the high-elasticity sealing member 440, and as the distance between the first movable member 410 and the second movable member 420 decreases, the light-transmitting rod 430 deforms the sealing member 440, and the light-transmitting hole in the sealing member 440 deforms to become larger. The optical fiber bundle sent by the coaxially arranged signal sensing piece 210 after the light hole is enlarged can pass through the sensing optical fiber signal, and at the moment, the approaching sensing piece 600 senses the cylinder body 310, so that the pushing mechanism is sensed to reach the pushing termination position, and the device can be judged to have pushed materials.
Meanwhile, in the axial movement process of the cylinder body 310 along the stainless steel tube 320, if the material is not pushed to the end position, but the pushing member 500 cannot push the material continuously, the material jamming condition occurs. At this time, the pushing mechanism is in a moving state that the pushing element 500 and the second moving element 420 cannot move continuously along the first guide shaft 451 and are not stopped, but the first moving element 410 is connected to the cylinder body 310, and the cylinder body 310 still drives the first moving element 410 to move continuously along the axial direction of the first guide shaft 451, so that the second moving element 420 is not moved, and the first moving element 410 moves continuously, resulting in a decrease in the distance between the first moving element 410 and the second moving element 420. Since the light-transmitting rod 430 is fixed on the second moving member 420, the distance between the second moving member 420 and the first moving member 410 decreases, and the end of the light-transmitting rod 430 facing the first moving member 410 contacts the sealing member 440, and as the distance between the second moving member 420 and the first moving member 410 decreases, the light-transmitting rod 430 deforms the sealing member 440, and the light-transmitting hole in the sealing member 440 deforms and becomes larger. The optical fiber bundle sent by the coaxially arranged signal sensing element 210 can pass through after the light hole is enlarged, the coaxially arranged signal sensing element 210 can sense an optical fiber signal, and the left side approaching sensing element 600 does not sense that the moving assembly 400 reaches the pushing termination position, so that the device can be judged to have a material blocking condition, and an automatic alarm can be given.
If the signal sensing piece 210 and the proximity sensing piece 600 both sense signals, the material pushing mechanism is in a material pushing completion state; if the signal sensing member 210 senses a signal, the approaching sensing member 600 does not sense the signal, and the material pushing mechanism is in a material clamping state; if the signal sensing piece 210 and the approaching sensing piece 600 cannot sense the signal, the material pushing mechanism is in a material pushing in-process state. In summary, the mechanism can determine the state of the mechanism according to the signals of the signal sensor 210 and the proximity sensor 600.

It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the present invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined by the appended claims and their equivalents.
