The embodiments will be described in detail below with reference to the accompanying drawings.
For a better understanding of the technical solutions and effects of the present application, specific embodiments will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, a first aspect of the present application provides a bearing device 100, including: the support assembly 1, slide rail 2 and pressure-bearing assembly 3. The slide rail 2 is arranged on one side of the support component 1; the bearing component 3 is arranged on one side of the support component 1 departing from the slide rail 2, one end of the bearing component 3 far away from the support component 1 is provided with a groove 31, the groove 31 comprises a first surface 311 and a second surface 312 used for supporting a coil stock, and the spacing distance between the first surface 311 and the second surface 312 is gradually increased along the direction from the support component 1 to the bearing component 3.
The depth of the groove 31 and the angle between the first surface 311 and the second surface 312 of the groove 31 are not limited in the present application, and an appropriate groove 31 may be selected according to the size of the roll to be actually received. It will be appreciated that when the web size is larger, the grooves 31 may be selected to have a greater depth, and/or the grooves 31 may be selected to have a greater angle between the first surface 311 and the second surface 312.
One end of the pressure bearing component 3, which is far away from the support component 1, is provided with a groove 31, and the groove 31 is used for bearing materials. The groove 31 includes a first surface 311 and a second surface 312, and a spaced distance between the first surface 311 and the second surface 312 is gradually increased in a direction from the support assembly 1 to the bearing assembly 3. Alternatively, the first surface 311 and the second surface 312 may have a V-shaped slope therebetween. The V-shaped inclined surface can better adapt to roll materials with different sizes. The first surface 311 and the second surface 312 may be flat surfaces that are obliquely disposed.
Referring to fig. 2, the first surface 311 and the second surface 312 may be curved surfaces protruding outward. The web rolls on the first surface 311 and the second surface 312 after contacting the groove 31 due to the influence of gravity, and when the gravity of the web and the pressure exerted by the web on the first surface 311 and the second surface 312 are balanced, the web stops moving on the first surface 311 and the second surface 312. When the first surface 311 and the second surface 312 are curved surfaces protruding outward, the friction force generated when the first surface 311 and the second surface 312 receive the roll material can be reduced. When the gravity of the roll material and the pressure applied by the roll material on the first surface 311 and the second surface 312 reach an equilibrium, the center of gravity of the roll material and the center point of the groove 31 coincide on the same extension line. Thereby realizing the function of automatic deviation rectification of the pressure-bearing device 100.
Optionally, anti-slip bumps may be disposed on the first surface 311 and the second surface 312, and the bumps can increase friction between the roll material and the first surface 311 and the second surface 312, so that the roll material can be prevented from slipping to some extent, and the positioning effect is improved.
Referring to fig. 1, the pressure-bearing device 100 includes a slide rail 2, the slide rail 2 is disposed on one side of the support assembly 1, and the pressure-bearing assembly 3 is disposed on one side of the support assembly 1 away from the slide rail 2. The sliding rail 2 and the pressure-bearing assembly 3 are respectively arranged at two opposite sides of the supporting assembly 1, and the pressure-bearing device 100 can slide through the sliding rail 2. During the process of receiving the coil by the pressure-bearing assembly 3, the coil is in contact with the first surface 311 and the second surface 312, and if the coil is accurately abutted with the first surface 311 and the second surface 312, the pressures applied by the coil on the first surface 311 and the second surface 312 are the same, so that the component forces of the first surface 311 and the second surface 312 in the horizontal direction are the same, and the relative positions of the pressure-bearing assembly 3 and the slide rail 2 are kept unchanged. When the pressure applied by the coil material to the first surface 311 and the second surface 312 is not uniform, the component force of the first surface 311 and the second surface 312 in the horizontal direction is different, and under the component force in the horizontal direction, the pressure-bearing assembly 3 moves along the slide rail 2 until the first surface 311 and the second surface 312 are balanced in stress. When the pressure-bearing device 100 stops moving, the pressure applied by the coil materials on the first surface 311 and the second surface 312 reaches balance, and the acting force between the pressure-bearing device 100 and the coil materials automatically corrects the deviation, so that accurate butt joint is realized.
The pressure-bearing device 100 provided by the embodiment of the application can automatically correct the deviation generated by butt joint through the gravity of the coil stock, can reduce the manual deviation correction operation, and is more convenient to use. Compared with the realization of deviation correction by a laser scheme, the pressure-bearing device 100 provided by the embodiment of the application has the advantages of simple structure and low manufacturing cost, and compared with the realization of deviation correction by a visual scheme, the pressure-bearing device 100 provided by the embodiment of the application has higher butt joint precision.
Optionally, the pressure-bearing assembly 3 includes a pressure-bearing seat and a pressure plate 32, the groove 31 is disposed on the pressure-bearing seat, and the pressure-bearing seat and the pressure plate 32 may be an integral piece, which may reduce the production cost of the pressure-bearing apparatus 100. Or, the bearing seat and the pressing plate 32 are detachably connected by a bolt, and when the bearing device 100 is used for bearing various sizes of coil materials, the bearing seat more conforming to the size of the coil material can be replaced aiming at the coil materials with different sizes, so that the precision of the bearing device 100 is improved. And the pressure-bearing seat can be dismantled with clamp plate 32 and be connected, can not change clamp plate 32 when changing the pressure-bearing seat, multiplicable pressure-bearing device 100's practicality can also reduce pressure-bearing device 100's cost.
In some embodiments, the support assembly 1 includes a base 11 and a lift assembly 12, the lift assembly 12 connecting the pressure bearing assembly 3 with the base 11.
In these alternative embodiments, the lifting assembly 12 connects the bearing assembly 3 with the base 11. The lifting assembly 12 supports the pressure containing assembly 3 for movement relative to the base 11. It can be understood by those skilled in the art that when the bearing assembly 3 receives the roll material, the bearing assembly 3 moves toward the base 11, and when the bearing assembly 3 unloads the roll material, the bearing assembly 3 resets toward the direction away from the base 11.
In some embodiments, the lifting assembly 12 includes a sliding member 121 and a fixing shaft 122, the sliding member 121 is sleeved on the fixing shaft 122 and moves axially along the fixing shaft 122, the sliding member 121 is connected to the base 11, and the fixing shaft 122 is connected to the pressure-bearing assembly 3.
The fixed shaft 122 is connected with the pressure bearing assembly 3, and the fixed shaft 122 is used for bearing the force applied by the coil stock to the pressure bearing assembly 3. The sliding member 121 can reduce the friction generated during the loading of the roll by the pressure bearing device 100. The sliding member 121 is sleeved on the fixed shaft 122 and moves along the fixed shaft 122 axially, and the fixed shaft 122 can guide the sliding member 121. The sliding member 121 is connected to the base 11, and when the sliding member 121 moves along the fixed shaft 122, the base 11 also moves along with the sliding member 121.
Alternatively, the sliding member 121 may be a ball spline, which has excellent structural rigidity and extremely low sliding resistance and can withstand a large load. Therefore, when the ball spline moves axially relative to the fixed shaft 122, the resistance in the vertical direction is small, so that the pressure bearing assembly 3 can completely bear the gravity of the roll material. In this way, the slider 121 can reduce the influence of the resistance on the accuracy of the pressure receiving apparatus 100, thereby improving the reliability of the pressure receiving apparatus 100. Further, when the volume and the weight of the coil materials loaded by the pressure-bearing device 100 are large, the rigid structure of the ball spline is good, and the service life of the sliding part 121 can be prolonged by using the ball spline as the sliding part 121.
Alternatively, when the weight of the coil stock received by the pressure receiving device 100 is small, a ball bearing may be selected as the sliding member 121, and the ball bearing reduces the friction force during the force transmission process and improves the force transmission efficiency in a rolling manner when moving axially along the fixed shaft 122.
The lifting assembly 12 can be multiple, and the lifting assembly 12 can reduce the resistance in the vertical direction, so that the force applied to the pressure bearing device 100 by the coil stock is more uniform, and the accuracy of the pressure bearing device 100 is improved.
It will be appreciated by those skilled in the art that the lifting assembly 12 further includes a reset member (not shown) for resetting the slide 121.
In some embodiments, the lifting assembly 12 includes a baffle 123, the baffle 123 is disposed on a side of the fixed shaft 122 away from the bearing assembly 3, and the baffle 123 is used for limiting the axial movement of the sliding member 121 along the fixed shaft 122. When the sliding element 121 moves axially along the fixed shaft 122 to the end of the fixed shaft 122, the baffle 123 limits the position of the sliding element 121, so that the sliding element 121 is prevented from being separated from the fixed shaft 122.
In some embodiments, the bearing device 100 further includes a sensor 33, and the sensor 33 is disposed on a side of the base 11 adjacent to the bearing assembly 3.
Optionally, the sensor 33 is disposed between the bearing assembly 3 and the support assembly 1, and the sensor 33 is disposed on one side of the base 11 close to the bearing assembly 3. When the coil stock is placed on the pressure-bearing assembly 3, the pressure-bearing assembly 3 is pressed by the coil stock to move downwards along the vertical direction, or when the base 11 is driven by the vertical upward driving force to move upwards, the sensor 33 and the pressure-bearing assembly 3 are close to each other, and the sensor 33 can be used for detecting the weight of the coil stock borne by the pressure-bearing device 100.
Optionally, one side of the pressure bearing assembly 3 close to the sensor 33 includes a pressing sheet, the pressing sheet is butted with the sensor 33, the pressing sheet transmits the weight of the coil stock to the sensor 33, and the sensor 33 acquires the weight of the coil stock. The surface of the tablet is hardened, so that deformation such as indentation generated on the surface of the tablet can be reduced, and the accuracy of the pressure signal transmitted to the sensor 33 by the tablet is improved.
In some embodiments, the number of the support assemblies 1 is two, and the two support assemblies 1 are arranged at intervals along the extending direction of the slide rail 2.
A pressure device 100 comprises two support assemblies 1, and the coil stock carried by the pressure device 100 is placed between the two support assemblies 1, and the two support assemblies 1 can improve the stability and the balance of the pressure device 100. Two supporting component 1 set up along the extending direction interval of slide rail 2, and when the pressure of the coil stock that two supporting component 1 received had the size difference, pressure-bearing device 100 was followed slide rail 2 and removed by the influence of pressure, and when the pressure balance of the coil stock that two supporting component 1 received, and when no external force drive pressure-bearing device 100 removed, then pressure-bearing device 100 stopped to remove.
In some embodiments, the first surface 311 and the second surface 312 are arranged in mirror image along the symmetry axis of the two support members 1.
Optionally, the first surface 311 and the second surface 312 are arranged in a mirror image along the symmetry axis of the two support assemblies 1, and the pressure of the roll material received by the first surface 311 and the second surface 312 can be uniformly applied to the two support assemblies 1, so that the stability and accuracy of the pressure-bearing device 100 in the use process can be improved.
Referring to fig. 3, a transportation vehicle 200 is provided in a second aspect of the present application, and includes any one of the pressure-bearing devices 100 provided in the first aspect of the present application, and a driving assembly 4, where the driving assembly 4 is connected to the sliding rail 2, and the driving assembly 4 is used for driving the pressure-bearing device 100 to move in a vertical direction.
The transport vehicle 200 is used for receiving materials on the emptying device. Fig. 4 shows a partial emptying device, which comprises a reel 5, a roll of material 6 wound on the reel 5, and an air shaft 7. An air shaft 7 is placed inside the spool 5 to support the spool 5. The discharging device can comprise two inflatable shafts 7 arranged at two opposite ends of the winding drum 5, and after the inflatable shafts 7 are deflated and contracted, the inflatable shafts 7 are drawn out from two ends of the winding drum 5 to complete a discharging process. Alternatively, the discharging device can comprise an air expansion shaft 7, and the winding drum 5 is sleeved on the air expansion shaft 7.
Optionally, the transport vehicle 200 may be an automatic transport vehicle that receives the instruction signal, the transport vehicle 200 is electrically connected to the scheduling device, the scheduling device is electrically connected to the signal terminal, the signal terminal sends the coil material demand information to the scheduling device, the scheduling device analyzes the received coil material demand information, and then the scheduling device sends an instruction for transporting the coil material to the transport vehicle 200 that is located near the coil stock bin and in an idle state, and plans a traveling path of the transport vehicle 200, so that the transport vehicle 200 transports the coil material from the coil stock bin to a place where the coil material is needed. The user can also directly send an instruction to the dispatching equipment through the signal terminal, so that the transport vehicle 200 can transport the coil materials required by the user.
Optionally, the transportation vehicle 200 may also be manually operated, and when the scheduling device or the signal terminal has a fault, the transportation vehicle 200 may also be manually operated, so as to increase the application range of the transportation vehicle 200. The transport vehicle 200 may include one or more pressure-bearing devices 100, and when one pressure-bearing device 100 receives the roll material 6, it is necessary to align the pressure-bearing device 100 with the central point of the roll material 6, so as to avoid the situation that the roll material 6 slides down obliquely. Two pressure-bearing devices 100 can be arranged at the two symmetrical ends of the coil stock 6, thereby improving the stability of the bearing.
Optionally, the driving assembly 4 can be a hydraulic driving part, the overall structure of the hydraulic driving part is simple, the force is large, the working performance is stable, and the manufacturing cost is low.
The transportation vehicle 200 may include a sliding groove corresponding to the sliding rail 2, and a driving member driving the pressure receiving device 100 to move along the sliding groove. The driving member can drive the pressure-bearing device 100 to move along the chute to the position below the coil stock 6.
It can be understood that the emptying device can also comprise a rotating arm, and the rotating arm supports the roll material 6 to rotate to the butt joint position, and then the air expansion shaft 7 contracts. The inner diameter D of the winding drum 5 is 3-4mm larger than the outer diameter D of the inflatable shaft 7. Therefore, a gap is formed between the inner diameter D of the spool 5 and the outer diameter D of the air shaft 7. Taking the vertical direction as an example, the upper and lower gaps between the inner diameter D of the winding drum 5 and the outer diameter D of the air expansion shaft 7 are Δ H1 and Δ H2, respectively, and the driving assembly 4 of the transport vehicle 200 drives the pressure-bearing device 100 to move in the vertical direction and is in butt joint with the discharging device to receive the coil stock 6. The abutting state of the coil 6 pressure-bearing device 100 can be judged by comparing the values between the delta H1 and the delta H2. The changes in Δ H1 and Δ H2 may include the following three processes.
First, Δ H1 has a value greater than zero and Δ H2 has a value equal to zero. As the web 6 is wound on the reel 5, the web 6 exerts a pressure on the air-expanding shaft 7. At this time, the clearance Δ H2 between the reel 5 and the inflatable shaft 7 is zero in the vertical direction, and the inner diameter D of the reel 5 is 3-4mm larger than the outer diameter D of the inflatable shaft 7, so the value Δ H1 is larger than zero.
Second, Δ H1 is greater than zero and Δ H2 is greater than zero. The driving assembly 4 drives the pressure bearing device 100 to move upwards along the vertical direction, the winding drum 5 is supported by the pressure bearing device 100 at the moment, the winding drum 5 cannot be in contact with the air expansion shaft 7, the value of the delta H2 is increased, the value of the delta H1 is reduced, and the values of the delta H1 and the delta H2 are both larger than zero in the process.
Third, Δ H1 has a value equal to zero and Δ H2 has a value greater than zero. The driving assembly 4 continues to drive the pressure-bearing device 100 to move upwards in the vertical direction, so that the winding drum 5 applies a vertical upwards force to the air expansion shaft 7, the value of Δ H1 is zero, and the value of Δ H2 is greater than zero.
Alternatively, the driving assembly 4 drives the bearing device 100 to move upward in the vertical direction. At this time, the value of the sensor 33 of the pressure receiving apparatus 100 also changes with changes in Δ H1 and Δ H2. In a first process, the sensor 33 contacts and lifts the web 6, the value of the sensor 33 gradually increasing. In the second process, the sensor 33 now receives the weight of the web 6, so that the value of the sensor 33 does not change. In a third process, the value of the sensor 33 increases as a result of the web 6 exerting a vertical upward force on the air-lift shaft 7.
Referring to fig. 4, a third aspect of the present application provides a coil receiving method applied to a transport vehicle provided in the second aspect of the present application, and the method may include:
s100, controlling a driving assembly to drive a pressure-bearing device to move towards the direction close to a coil stock along the vertical direction;
s200, acquiring a stress value and/or a clearance parameter of the sensor numerical value pressure-bearing assembly, and controlling the driving assembly to stop according to the change of the stress value and/or the clearance parameter, wherein the clearance parameter comprises a clearance value of the winding drum and an air expansion shaft arranged in the winding drum along the vertical direction.
The clearance parameters comprise a first clearance value and a second clearance value, the first clearance value is a clearance value between the inner wall of the winding drum close to the pressure-bearing device and the air expansion shaft along the vertical direction, and the second clearance value is a clearance value between the inner wall of the winding drum far away from the pressure-bearing device and the air expansion shaft along the vertical direction.
As an alternative embodiment, S200, acquiring a stress value and/or a clearance parameter of the pressure-bearing assembly, and controlling the driving assembly to stop according to a change of the stress value and/or the clearance parameter may include: s201, acquiring a first gap value and a second gap value, and controlling the driving assembly to stop when the first gap value is equal to the second gap value.
As an alternative embodiment, before S100, the transport vehicle may be controlled to move to a position below the discharging device in advance, and then the driving assembly is controlled to drive the pressure-bearing device to move in the vertical direction to receive the coil stock. Through the above analysis of the embodiment of the second aspect of the present application, the receiving state between the transport vehicle and the coil stock can be judged through the first gap value and the second gap value, which is not described herein again. Under the condition that the weight of the coil stock is known, when the value of the sensor is not changed, the value of the sensor is equal to the gravity of the coil stock, and the driving assembly is controlled to stop at the moment to finish the butt joint process.
Under the condition that the weight of the coil stock is unknown, and under the condition that the first gap value and the second gap value are equal, the pressure-bearing device completely bears the weight of the coil stock, and at the moment, the driving assembly is controlled to stop, and the butt joint procedure is completed.
It can be understood that, in the case that both the first gap value and the second gap value are greater than zero, the pressure-bearing device also completely bears the weight of the coil, and at this time, the driving assembly is controlled to stop, and the docking procedure is completed.
As an optional embodiment, after S200, S300 may be further included, and the transport vehicle is controlled to move and transport the coil stock.
