Based on the above, the utility model provides the pushing device, the length and the diameter of the material can be measured while the material is conveyed, so that the material with the size can be conveyed to the stacking area of the corresponding size interval, the material size does not need to be manually measured and the material does not need to be distinguished during subsequent stacking, the working efficiency is effectively improved, and the labor cost is reduced.

Some embodiments of the utility model are described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic structural view of a material pushing device according to an embodiment of the present invention, and the first direction is an X direction and the second direction is a Y direction, taking the placement view of fig. 1 as an example. As shown in fig. 1, a material pushing apparatus 10 according to an embodiment of the present invention includes a first measuring mechanism 100 and a second measuring mechanism 200 spaced apart from each other in the X direction; the first measuring mechanism 100 can move along the X direction, and the first measuring mechanism 100 and the second measuring mechanism 200 can clamp the material together to obtain the length dimension of the material; the second measuring mechanism 200 includes a first pair of clamping plates 211 and a second pair of clamping plates 212 that are oppositely disposed in the Y direction; the first pair of jaws 211 and the second pair of jaws 212 can be moved towards each other simultaneously to clamp the material together and obtain the radial dimension of the material.

It should be noted that the material includes, but is not limited to, material or profile, if the cross section of the material is square, the radial dimension is the side length of the material, and if the cross section of the material is circular, the radial dimension is the diameter of the material. The material pushing device 10 measures the length of the material through the first measuring mechanism 100, and then measures the diameter or the side length of the material through the second measuring mechanism 200.

In this embodiment, after the material enters the material pushing device 10, the first pair of clamping plates 211 and the second pair of clamping plates 212 move towards each other, so that the material cannot pass through between the second measuring mechanisms 200, and the second measuring mechanisms 200 can function as a material stop. Then, the first measuring mechanism 100 moves in a direction close to the second measuring mechanism 200, so that the first measuring mechanism 100 abuts against one end of the material first, and with the continued movement of the first measuring mechanism 100, pushes the other end of the material to abut against the second measuring mechanism 200. Recording the distance between the first measuring mechanism 100 and the second measuring mechanism 200 before movement as a first initial distance; when the material is moved to abut against the second measuring mechanism 200, the moving distance of the first measuring mechanism 100 is recorded as a first moving distance. At this point, the length of the material is equal to the first initial distance minus the first travel distance. In other embodiments, the length of the material may also be directly obtained by the distance between the first measuring mechanism 100 and the second measuring mechanism 200 after the movement.

After the length of the material is measured, the first pair of clamping plates 211 and the second pair of clamping plates 212 are reset, that is, the first pair of clamping plates 211 and the second pair of clamping plates 212 are restored to the position before the movement, so that the material can pass through the second measuring mechanism 200. The distance between the first pair of jaws 211 and the second pair of jaws 212 after repositioning is recorded as a second initial distance. When the material moves between the first pair of jaws 211 and the second pair of jaws 212, the first pair of jaws 211 and the second pair of jaws 212 move towards each other at the same time until the material is clamped. The distance to move the first pair of clamping plates 211 or the second pair of clamping plates 212 is the second moving distance. At this point, the diameter of the material is equal to the second initial distance minus twice the second travel distance. In other embodiments, the first pair of jaws 211 may be moved in a direction closer to the second pair of jaws 212, and the second pair of jaws 212 may be stationary, wherein the diameter of the material is the second initial distance minus the distance moved by the first pair of jaws 211.

Fig. 2 is a partially enlarged view of a portion a shown in fig. 1, and fig. 3 is a schematic view of the first measuring mechanism 100 shown in fig. 1. Further, as shown in fig. 1 to 3, the first measuring mechanism 100 includes a first moving assembly 110 and a push plate 130 connected to an output end of the first moving assembly 110, and the first moving assembly 110 is configured to drive the push plate 130 to move along the X direction, so as to drive the materials to move synchronously. Thus, the first initial distance is the distance from the push plate 130 to the second measuring mechanism 200, and the first moving distance is the moving distance of the push plate 130, so that the length of the material can be obtained by subtracting the first moving distance from the first initial distance. In this embodiment, the first moving assembly 110 may include a first driving member 111 and a first gear 112 connected to a power output end of the first driving member 111, wherein the first driving member 111 is used for driving the first gear 112 to rotate around its axis. The material pushing device 10 further comprises a rack 300, wherein a feeding groove is formed in the rack 300 and used for placing materials, the feeding groove can be a V-shaped groove or a rectangular groove, and a first rack 311 is installed on the rack 300. Therefore, the first gear 112 can be driven to rotate by the first driving member 111, and since the first gear 112 is meshed with the first rack 311 and the first rack 311 is fixed, the first gear 112 and the first driving member 111 move along the extending direction of the first rack 311, thereby driving the push plate 130 to move synchronously. The first driving member 111 may be a first motor, and the first gear 112 is sleeved on an output rotating shaft of the first motor. In other embodiments, the first moving element 110 may also be a first linear module.

As shown in fig. 2, in order to make the movement of the first driving member 111 smoother, the frame 300 is further provided with a first guide rail 312 and a first slider 313 slidably connected to the first guide rail 312, and the first driving member 111 is fixedly connected to the first slider 313. The movement of the first driving member 111 and the first gear 112 can be guided by providing the first guide rail 312 and the first slider 313, and the driving force for the movement of the first gear 112 in the X direction can be reduced, so that the movement of the first measuring mechanism 100 is more smooth, thereby ensuring the measuring accuracy.

As shown in fig. 3, in an alternative embodiment, the first measuring mechanism 100 further includes a material pushing frame mounted on the frame 300, and a first telescoping assembly 120 mounted on the material pushing frame, wherein an end of the first telescoping assembly 120 away from the material pushing frame is connected to the pushing plate 130. The first telescopic assembly 120 can perform telescopic motion relative to the material pushing frame. First retraction assembly 120 has an initial position with first sensor 123 mounted therein and a compressed position with second sensor 124 mounted therein. When the first telescopic assembly is in the first state, namely the initial position, the first moving assembly 110 can be controlled to move through the first sensor 123, and when the first telescopic assembly is in the second state, namely the compression position, the first moving assembly 110 is controlled to stop through the second sensor 124. Thus, the first initial distance is the sum of the distance from the push plate 130 to the second measuring mechanism 200 and the compression amount of the first telescopic assembly 120 when the first telescopic assembly 120 is in the initial position. The first telescopic assembly 120 may be a cylinder, and includes a first cylinder 121 and a first piston rod 122, the first piston rod 122 is fixedly connected to the push plate 130, and the first sensor 123 and the second sensor 124 may be photoelectric switches. When the first piston rod 122 extends relative to the first cylinder 121, the position of the end of the first piston rod 122 away from the push plate 130 in the first cylinder 121 is the initial position. When the first piston rod 122 retracts relative to the first cylinder 121, the position of the end of the first piston rod 122 away from the push plate 130 in the first cylinder 121 is the compression position. The first and second photoelectric switches are respectively installed at the initial position and the compression position of the first cylinder 121, and a magnetic ring is disposed on the first piston rod 122.

In this embodiment, when the magnetic ring is in the initial position, the first photoelectric switch sends a signal, and the first moving component 110 operates, so that the first moving component 110 and the cylinder move towards the second measuring mechanism 200 simultaneously. During the movement process, when the magnetic ring moves to the compression position, it indicates that the material abuts against the second measuring mechanism 200, and therefore, the second photoelectric switch sends out a signal, so that the first moving assembly 110 stops moving. This is because when the material contacts the second measuring mechanism 200, as the first moving assembly 110 continues to move in a direction approaching the second measuring mechanism 200, the material applies a force to the push plate 130 opposite to the moving direction thereof, thereby retracting the first piston rod 122 which is initially extended. The advantage of using the cylinder is that the cylinder stable in structure, the telescopic link can move along fixed direction. More importantly, the cylinder can control the moving resistance of the telescopic rod by controlling the air pressure, so that the telescopic rod is suitable for pushing materials with different weights. Because the material is placed in the feeding groove, friction force exists between the material and the groove wall of the feeding groove in the moving process. When the weight of the material is light, the friction force is small, and the resistance air pressure of the air cylinder can be correspondingly set to be small, so that the push plate 130 can push the material to be abutted against the second measuring mechanism 200; when material weight is heavier, frictional force is great, and the resistance atmospheric pressure of cylinder can set up relatively great, when guaranteeing that second photoelectric switch signals, the material has leaned on with second measuring mechanism 200, and not because frictional force leads to the compression of cylinder piston rod. In other embodiments, first retraction assembly 120 may be a spring.

As shown in fig. 1, in an alternative embodiment, the material pushing device 10 further includes a third sensor 400, the third sensor 400 is mounted on a side of the frame 300 close to the first measuring mechanism 100, and when the material falls into the chute, the third sensor 400 is pressed down, so that the third sensor 400 sends a signal, and the first pair of clamping plates 211 moves close to the second pair of clamping plates 212, and the length of the material is measured by the stopping function of the second measuring mechanism 200.

Fig. 4 is a schematic view of the second measuring mechanism 200 shown in fig. 1. Further, as shown in fig. 4, the second measuring mechanism 200 further includes a fixing base 213 and a second driving member 214 mounted on the fixing base 213, and the first pair of clamping plates 211 is mounted on a power output end of the second driving member 214. The second driving member 214 is specifically a second cylinder, and a piston rod of the cylinder is connected with the first pair of clamping plates 211, so that the first pair of clamping plates 211 are close to or far away from the second pair of clamping plates 212 through the reciprocating motion of the piston rod, and the material blocking function and the diameter measuring function of the second measuring mechanism 200 are realized. In other embodiments, the second drive member 214 may also be a linear motor.

With reference to fig. 4, the second measuring mechanism 200 further includes a driving plate 224, one end of the driving plate 224 is fixedly connected to the piston rod of the second cylinder, and the other end of the driving plate 224 is fixedly connected to the first pair of clamping plates 211, and the driving plate 224 is driven by the piston rod to move, so as to drive the first pair of clamping plates 211 to move. Further, the second measuring mechanism 200 further includes a first sensing assembly 223 fixedly connected to the driving plate 224, and the first sensing assembly 223 can acquire the moving distance of the first pair of clamping plates 211. Specifically, the first sensing member 223 is a displacement sensor that detects a moving distance of the object to be detected by detecting a moving distance of a portion of the sensor. The main body of the displacement sensor is fixedly connected with the cylinder body of the second cylinder, the movable end of the sensor is fixed on the driving plate 224, and the driving plate 224 is fixed with the first pair of clamping plates 211, so that when the piston rod moves relative to the cylinder body, the driving plate 224 drives the first pair of clamping plates 211 and the movable end of the sensor to synchronously move, the second moving distance of the first pair of clamping plates 211 is the moving distance of the movable end of the displacement sensor, and the size of the clamped material can be obtained through the second initial distance and the second moving distance.

In this way, the movement of the first pair of clamping plates 211 and the second pair of clamping plates 212 can be guided by the second guide rail 215 and the third guide rail 218, respectively, so that the reliability of the device can be improved.

In order to better realize that the first pair of clamping plates 211 and the second pair of clamping plates 212 move towards each other at the same time, the second measuring mechanism 200 further comprises a second driving rack 217 and a second gear 221 in meshing transmission with the second driving rack 217, the second driving rack 217 is installed on the second sliding block 216, and the first pair of clamping plates 211 are installed on the second driving rack 217; and a second driven rack 222 in meshed transmission with the second gear 221, the second driven rack 222 being mounted on the third slider 219, and the second pair of clamping plates 212 being mounted on the second driven rack 222. Therefore, the vibration of the second driving rack 217 and the second driven rack 222 is reduced through the sliding block, and meanwhile, when the first pair of clamping plates 211 and the second pair of clamping plates 212 move towards each other simultaneously, the moving distance is guaranteed to be consistent, so that the measuring precision is guaranteed.
