Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1, a material turning apparatus 100 is shown for implementing a turning operation on a material that needs to be changed in spatial posture in various industries to meet processing requirements. For example, in the construction industry, the material may refer to rebar mesh 50. In order to facilitate welding of the reinforcing mesh 50, the material overturning device 100 can overturn the reinforcing mesh 50, and it can be understood that two opposite side surfaces of the reinforcing mesh 50 can be sequentially adjusted to a processing operation surface (the processing operation surface can be located above or below the reinforcing mesh 50) through overturning, so that welding and consolidation of longitudinal bars and transverse bars by the welding device are facilitated.

It should be noted that, for convenience of describing the technical solution, the material is taken as the reinforcing mesh 50 as an example for explanation. That is to say that material tipping arrangement 100 is used for realizing the upset of reinforcing bar net piece 50 in this scheme.

Referring to fig. 1, in detail, the material turning apparatus 100 in the embodiment includes: a support 10, a first-stage overturning actuating mechanism 20, a second-stage overturning actuating mechanism 30 and a bearing frame 40. The support 10 can be directly installed on the ground or other auxiliary fixing devices, and as a supporting base of the whole material turnover device 100, the support can be used for installing and fixing the first-stage turnover executing mechanism 20, the second-stage turnover executing mechanism 30, the bearing frame 40 and the reinforcing mesh sheet 50 placed on the bearing frame 40, so that the whole material turnover device 100 can work stably and reliably.

Alternatively, the support 10 is formed by welding or splicing steel structural members, and may be rectangular, circular, triangular, and the like. In order to ensure that the support 10 is installed more stably, a supporting plate can be additionally arranged at the bottom of the support to increase the supporting area and improve the supporting stability.

With reference to fig. 1, in addition, the primary flipping actuator 20 is rotatably disposed on the support 10, and the primary flipping actuator 20 includes a primary flipping driving member 23; the first-stage overturning driving part 23 is connected with the second-stage overturning executing mechanism 30 and can drive the second-stage overturning executing mechanism 30 to rotate, and the second-stage overturning executing mechanism 30 comprises a second-stage overturning driving part 32; the secondary turnover driving element 32 is connected with the bearing frame 40 and can drive the bearing frame 40 to rotate, and the bearing frame 40 is used for loading materials; the first-stage turnover executing mechanism 20 and the second-stage turnover executing mechanism 30 can sequentially or synchronously output rotary power to drive the bearing frame 40 to drive the material to turn over.

It can be understood that material tipping arrangement 100 still includes the controller, and the controller respectively with one-level upset actuating mechanism 20 and second grade upset actuating mechanism 30 electric connection, can control one-level upset actuating mechanism 20 and second grade upset actuating mechanism 30 respectively and successively or accomplish in step and open and stop the action, not only can promote the automation level of material tipping arrangement 100, change in the upset precision of guaranteeing reinforcing bar net piece 50 simultaneously.

Optionally, the controller may be a PLC, a micro-control computer, a numerical control system, or the like, and may be specifically selected according to actual needs.

In summary, the implementation of the technical solution of the present embodiment has the following beneficial effects: the material overturning equipment 100 is used for overturning materials in space to change the pose so as to meet the processing requirement. Specifically, the support 10 is used for bearing and fixing the first-stage turnover actuator 20, the second-stage turnover actuator 30 and the bearing frame 40, so as to ensure that the whole material turnover device 100 can reliably work. During production, the material is firstly installed on the bearing frame 40 and fixed, then the first-stage turnover executing mechanism 20 and the second-stage turnover executing mechanism 30 are started, and at the moment, the first-stage turnover executing mechanism 20 and the second-stage turnover executing mechanism 30 can output rotary power successively or synchronously, so that the bearing frame 40 can be synchronously driven to drive the material to complete turnover operation in space, and the purpose of changing the material pose is achieved. Compared with the mode that the material is lifted firstly and then overturned by traditional equipment, the scheme can effectively shorten the overturning action time, improve the operating efficiency of material overturning and improve the economical efficiency due to the fact that the height adjustment and the posture rotation synchronous adjustment can be realized.

In some embodiments, the primary turnover actuator 20 further includes a turnover arm 21 and a hinge seat 22, the turnover arm 21 is rotatably mounted on the hinge seat 22, the hinge seat 22 is disposed on the support 10, the primary turnover driving member 23 is disposed on the support 10 and is in driving connection with the turnover arm 21, and the turnover arm 21 can rotate relative to the support 10.

The primary turnover driving member 23 may be a cylinder, an electric push rod, or other power equipment capable of outputting telescopic power. Preferably, the primary tumble drive member 23 is provided as a cylinder in this embodiment. Because the turning arm 21 is rotatably connected with the hinged support 22, when the piston rod of the air cylinder extends out, the hinged support 22 can be used as a rotation fulcrum to drive the turning arm 21 to rotate, so that the purpose of driving the secondary turning actuator 30, the bearing frame 40 and the reinforcing mesh 50 placed on the bearing frame 40 to turn greatly (in a large angle) is achieved. The step of operation can also be understood as an operation of lifting the originally low-position steel mesh 50 to a high position, and aims to enable the overturning operation height to meet the inherent size of the steel mesh 50 and avoid collision and interference with the support 10 or other peripheral components when the subsequent steel mesh 50 is overturned.

With continued reference to fig. 1, it should be noted that the hinge base 22 is disposed at the side of the stand 10, and the hinge base 22 is hinged to a portion of the flip arm 21 near one end. This arrangement prevents interference with the support 10 when the invert arm 21 is inverted. The first-level overturning driving part 23 is arranged close to the free end of the overturning arm 21 so as to ensure that the piston rod can effectively drive the overturning arm 21 to overturn.

With reference to fig. 1, in addition, the two turning arms 21, the hinge base 22, the first-stage turning driving member 23, and the second-stage turning actuating mechanisms 30 are respectively disposed in a one-to-one correspondence manner, the two turning arms 21 are respectively disposed on two opposite sides of the bearing frame 40, and the two second-stage turning actuating mechanisms 30 are both connected to the bearing frame 40 in a rotation driving manner.

By adopting the structural arrangement, the two opposite sides of the bearing frame 40 can be limited at the same time, and the bearing frame 40 is ensured to be stressed evenly; on this basis, bear frame 40 and carry out more steadily when one-level upset, can avoid reinforcing bar net piece 50 to take place the landing, carry out the second grade drive upset to bearing frame 40 in step with the help of two second grade upset actuating mechanism 30 simultaneously, control reinforcing bar net piece 50's upset precision and the stability of upset in-process more easily.

It should be noted that, the process of posture transformation after the first-stage overturning executing mechanism 20 and the second-stage overturning executing mechanism 30 overturn the steel mesh 50 can be briefly described as follows: the mesh reinforcement 50 is mounted to the carrier 40, and in this initial state, the mesh reinforcement 50 is in a horizontal position with one side facing upward, and the welding surface (i.e., the welding device) is above the mesh reinforcement 50. In order to turn the other opposite side of the mesh reinforcement 50 to the upper side, the first-stage turnover actuator 20 starts to drive the turnover arm 21 to rotate in the counterclockwise direction, and at the same time, the second-stage turnover actuator 30 starts to drive the carriage 40 to rotate in the clockwise direction. When one side of the steel mesh 50 reaches the lowest point position (that is, the steel mesh 50 is in the vertical posture), the overturning arm 21 starts to rotate clockwise, and the bearing frame 40 continues to rotate clockwise under the driving of the second-stage overturning executing mechanism 30 until the originally lower side of the steel mesh 50 is adjusted to be above. Under the action mode of the two-stage linkage overturning, the requirement of the reinforcing mesh 50 on the space required by overturning is low, and meanwhile, the overturning operation efficiency of the reinforcing mesh 50 can be greatly improved.

Considering that the total weight of the loading frame 40 and the reinforcing mesh 50 is large, the overturning arms 21 arranged in a suspended structure may be unstable in structure and even break, and further, the primary overturning actuator 20 further comprises a reinforcing rod 24, and two ends of the reinforcing rod 24 are respectively connected with the two overturning arms 21. The reinforcing bar 24 can increase the strength and rigidity of the connection of the two invert arms 21, thereby avoiding the above-mentioned problems.

With reference to fig. 1, the material turning apparatus 100 further includes a flexible supporting column 60, and the flexible supporting column 60 is disposed on the support 10 and can abut against the turning arm 21. The flexible supporting seat is specifically installed at one end of the support 10 far away from the hinged support 22, and when the reinforcing mesh 50 is processed and the overturning arm 21 falls and resets, the flexible supporting seat can play a role in buffering and supporting the overturning arm 21.

With continued reference to fig. 1, in some embodiments, the secondary flipping actuator 30 further includes a mounting bracket 31, a transmission assembly 33, and a flipping driving shaft 34, wherein the secondary flipping driving member 32 is disposed on the flipping arm 21 through the mounting bracket 31, the transmission assembly 33 is in transmission connection with both the secondary flipping driving member 32 and the flipping driving shaft 34, and the flipping driving shaft 34 is rotatably disposed on the flipping arm 21 and connected to the carriage 40.

In this embodiment, the operation mode that reinforcing bar net piece 50 realized the upset specifically has two kinds: firstly, when the primary overturning executing mechanism 20 drives the overturning arm 21 to drive the reinforcing mesh sheet 50 to overturn greatly, the secondary overturning driving part 32 outputs the rotating power at the same time, and the transmission assembly 33 transmits the rotating power to the overturning driving shaft 34, so that the overturning driving shaft 34 can synchronously drive the bearing frame 40 to rotate by taking the axis as the center, and finally the pose overturning adjustment of the reinforcing mesh sheet 50 is completed. Secondly, the overturning actuating mechanism 20 drives the overturning arm 21 to drive the reinforcing mesh sheet 50 to overturn greatly, and then the second-stage overturning driving part 32 outputs rotating power, so that the overturning driving shaft 34 can further drive the bearing frame 40 to rotate with the axis being medium, and finally the pose overturning adjustment of the reinforcing mesh sheet 50 is completed.

In this embodiment, the secondary invert drive 32 and the transmission assembly 33 are both mounted to the outside of the invert arm 21 to avoid interference with the carriage 40 and to help reduce the lateral size of the material inverting apparatus 100.

It should be noted that, in the present embodiment, the turnover driving shaft 34 is preferably rotatably connected to the middle of the supporting frame 40, so as to not only ensure more uniform stress on the supporting frame 40, but also reduce the height space required for turnover, reduce the time consumption of turnover, and improve the turnover efficiency.

On the basis of the above embodiments, in some embodiments, the transmission assembly 33 includes a driving sprocket connected to the power shaft of the secondary tumble driving member 32, a chain connected coaxially to the tumble driving shaft 34, and a driven sprocket sleeved on the driving sprocket and the driven sprocket.

Accordingly, the secondary tumble drive 32 is provided as a motor. The driving sprocket is connected with a power shaft of the motor and can reliably transmit rotary power to the driven sprocket through a chain, the driven sprocket drives the coaxially connected overturning driving shaft 34 to rotate, and finally the purpose of driving the bearing frame 40 and the reinforcing mesh 50 on the bearing frame to overturn is achieved. By adopting the transmission structure of the chain and the chain wheel, the power transmission is stable and reliable, the driving efficiency and the reliability of the heavy bearing frame 40 and the reinforcing mesh 50 are higher, and the failure problems of slipping and the like can be effectively avoided.

Of course, in other embodiments, the above-mentioned chain and sprocket transmission structure can be replaced by a synchronous pulley structure in the prior art, and the like, and is also within the protection scope of the present application.

In particular, on the basis of any of the above embodiments, the material turning device 100 further comprises an inclination sensor, which is arranged on the turning arm 21. Through the installation of the tilt angle sensor, the position information of the reinforcing steel bar net piece 50 can be fed back in real time in the overturning process, and the first-stage overturning executing mechanism 20 and the second-stage overturning executing mechanism 30 are assisted to finish automatic action control, so that the overturning position precision of the reinforcing steel bar net piece 50 is guaranteed.

Specifically, during normal operation, the controller reads the position information output by the tilt sensor, compares the position information with the target position information, calculates the action information required to be executed by the first-stage overturning driving member 23, completes the execution of the action in a telescopic mode of the first-stage overturning driving member 23, and completes the first-stage overturning action.

In addition, on the basis of any of the above embodiments, the material turning device 100 further includes a clamping mechanism, which is disposed on the carrier 40 and is used for clamping and fixing the material. Thereby can effectively avoid bearing frame 40 slope or when inverting reinforcing bar net piece 50 take place the pine to take off the landing, influence the upset operation and normally go on.

In consideration of actual manufacturing, the facing reinforcing mesh 50 is different in size, and the span of the size may be large. For example, the conventional mesh sheet 50 is rectangular, and the length and width of the mesh sheet vary from a few tenths of meters to several meters, so that the clamping mechanism needs to have better universality and universality. The following three embodiments of clamping mechanism solutions are provided in the present application. Embodiments 1 and 2 can be used to fix a small rebar mesh 50 within a certain size range, and embodiment 3 can be suitable for fixing rebar meshes 50 with large size variation due to the large adjustable stroke.

In the present embodiment, the driver 72 is provided as an air cylinder.

In the initial state, the telescopic rod of the cylinder is retracted, the hinge shaft 73 is located at the end of the first guide hole 41 closest to the cylinder, and the hinge shaft 73 is located at the lowermost end of the second guide hole 42. Due to the constraint action of the hinge shaft 73 and the hole wall of the second guide hole 42, the clamping jaw 74 is in an outward-spreading inclined posture, and can avoid a bearing surface above the bearing frame 40 for loading the reinforcing mesh 50. When the reinforcing mesh sheet 50 is placed on the bearing surface, the cylinder drives the telescopic rod to extend, the hinge shaft 73 slides in the first guide hole 41, is far away from the cylinder and pushes against the hole wall of the second guide hole 42, and the hinge shaft 73 slides upwards in the second guide hole 42 to force the clamping jaw 74 to turn inwards. Finally, the claw hooks of the clamping jaws 74 are buckled on the upper surface of the steel mesh 50, namely the two clamping jaws 74 at the two ends synchronously hook and buckle the longitudinal bars or the transverse bars of the steel mesh 50, so that the purpose of limiting the freedom degree of the steel mesh 50 and ensuring the stable installation is realized.

Further, the clamping assembly 70 further includes a clip 75, and the clip 75 is disposed on the clamping jaw 74. By arranging the clamping pieces 75, the contact area between the clamping jaws 74 and the steel mesh sheet 50 can be increased, so that the purpose of further firmly fixing the steel mesh sheet 50 is achieved.

Alternatively, the clip 75 is a flat piece of sheet metal that may be removably attached to the jaws 74 or may be integrally attached thereto. Furthermore, the side of the clip 75 facing the steel mesh 50 is provided with an array of protruding structures, and the protruding structures can be clamped with the side of the longitudinal bar or the transverse bar, so as to further reliably fix the steel mesh 50.

Example 2

With continuing reference to fig. 5 to 7, the clamping mechanism includes at least one pair of clamping assemblies 70, the clamping assemblies 70 include a fixing plate 71, a driver 72 for outputting telescopic power, a first hinge shaft 76, a second hinge shaft 77 and a clamping jaw 74, the driver 72 is disposed on the carrier 40 through the fixing plate 71, the first hinge shaft 76 is connected to a telescopic rod of the driver 72, the clamping jaw 74 is connected to both the first hinge shaft 76 and the second hinge shaft 77, the carrier 40 is formed with a first guiding hole 41, a second guiding hole 42 and an avoiding notch 43, the second guiding hole 42 is disposed to extend obliquely upward toward the avoiding notch 43, the clamping jaw 74 is formed with a third guiding hole 742 extending vertically, the first hinge shaft 76 is inserted into the first guiding hole 41 and the third guiding hole 742 in a sliding manner, the second hinge shaft 77 is slidably inserted into the second guide hole 42, and the clamping jaw 74 can extend out of the avoiding gap 43 or be hidden under the avoiding gap 43.

The main structure of the present embodiment 2 is substantially the same as that of the embodiment 1, and the difference is only in the mounting structure and the moving manner of the clamping jaw 74. In this embodiment 2, when the air cylinder (i.e., the driver 72) outputs the pushing force, the clamping jaw 74 moves obliquely upward along the second guide hole 42 disposed obliquely through the second hinge shaft 77 and finally extends out of the escape notch 43, so that the claw hook of the clamping jaw 74 is hooked on the side of the mesh sheet 50, thereby achieving the purpose of fixing the mesh sheet 50. The first hinge shaft 76 is inserted into and engaged with the first guide hole 41 and the third guide hole 742 which are vertically arranged, so that the horizontally output telescopic power is converted into a transverse driving force for the clamping jaw 74, and the switching between extending out of the avoidance notch 43 and being hidden below the avoidance notch 43 can be flexibly performed.

Particularly, in the oblique-out and oblique-in manner of this embodiment, the interference between the clamping jaw 74 and the steel mesh 50 can be better avoided, and the clamping jaw 74 can meet the clamping requirement of the steel mesh 50 with a larger area and a larger thickness.
