Description

Technical Field

[0001] The present invention relates to the technical field of bundling equipment, and particularly to a grid frame rod packaging equipment. Background Art

[0002] As the main load-bearing members, the transportation and storage of grid frame rods need to ensure stability and safety. Traditional bundling methods such as ropes or plastic tapes have problems such as insufficient strength and easy loosening. Due to its high strength, corrosion resistance and tensile properties, steel belts have become a more reliable bundling material. In the production process of grid frame rods, after manufacturing, these grid frame rods need to be efficiently transported to the designated bundling area. The bundling operation is to stack multiple grid frame rods in an orderly manner and tightly fix them with bundling belts for subsequent storage and sales. However, the three key links of conveying, precise placement and bundling involved in this process significantly affect the overall processing efficiency.

[0003] The Chinese patent document with the authorization announcement number CN107738773B discloses an automatic steel pipe bundling equipment, which relates to the technical field of steel pipe bundling. It includes a transportation device for transporting steel pipes, a support device for supporting steel pipes, a bundling device arranged above the transportation device, and a control device. The control device is respectively connected to the transportation device, the support device and the bundling device. The long axis of the steel pipe is parallel to the movement direction of the bundling device, and the movement direction of the bundling device is perpendicular to the transportation direction of the transportation device. The automatic steel pipe bundling equipment provided in this patent document realizes multi-pass bundling in the length direction of the steel pipes stacked in a certain shape without movement by moving the movable bundling device along the long axis direction of the steel pipes.

[0004] Existing pipe bundling devices usually use a steel belt to wind around one end of a pipe stack during bundling, then cut the steel belt, and then connect the head and tail of the steel belt by welding or buckling to bundle the pipe stack. When it is necessary to disassemble the pipe stack, since the pipe above has a large gravitational potential energy, after cutting the steel belt, the pipes collapse, and it is easy to cause the pipes to roll a long distance. Therefore, the pipes need to be placed in an open space or on a professional support frame to avoid the pipes hitting other objects and causing damage to the pipes or other equipment. In summary, when removing the steel belt, a suitable site or professional equipment is required, so there are great limitations when removing the steel belt. Summary of the Invention

[0005] The present invention provides a grid frame rod packaging equipment, aiming to solve the problem that when removing the steel belt on a pipe stack in the related art, the pipes will roll a long distance.

[0006] A grid bar packaging device includes a conveying device for conveying a stack of grid bars and a bundling device for bundling steel belts on the stack of grid bars. It also includes a plurality of fixing members arranged between the first layer of grid bars and the second layer of grid bars. The fixing member includes two arc-shaped plates that are staggered front and back and face different directions. The curvature of the arc-shaped plates is adapted to the grid bars. The two arc-shaped plates are separably connected, and an elastic band is connected between the two arc-shaped plates. An elastic piece is slidably mounted front and back at the top of the arc-shaped plate. A card slot is provided at the upper part of the elastic piece. The left, right, and rear ends of the card slot are open, and the height of the card slot is the same as the thickness of the steel belt. A check structure is provided between the elastic piece and the arc-shaped plate to prevent the elastic piece from sliding in the reverse direction after the card slot is stuck on the steel belt. In the initial state, in the front view projection plane, the tops of the two elastic pieces are both located in the middle above the stack of grid bars. After the steel belt is bundled, the card slots on the two elastic pieces are respectively stuck on two adjacent steel belts and are respectively located on the left and right sides of the connection of the steel belts.

[0007] The effect is as follows: During the stacking process of the grid bars, when stacking to the second layer, install the fixing member on the second layer of grid bars, and then place the first layer of grid bars, so that the arc-shaped plates are fixed between the first layer and the second layer of grid bars. Subsequently, according to the position of the arc-shaped plates, use the bundling device to tightly bundle the stack of grid bars with the steel belt at a suitable position. Finally, insert the card slots onto the steel belts, thus connecting the fixing member and the steel belts together. When the stack of grid bars moves to the destination, place the stack of grid bars on the ground, and then cut one end of the connection of the steel belt away from the card slot. The two adjacent cut steel belts are connected by the elastic member, the arc-shaped plates, and the elastic band. When the stack of grid bars collapses, the fracture of the steel belt moves to both sides, thereby stretching the elastic band and causing the elastic band to deform and elongate, further limiting the position of the arc-shaped plates, making the arc-shaped plates closely adhere to the hooked grid bars, avoiding the arc-shaped plates from falling off, thereby limiting the rolling range of the grid bars, while weakening the collapse speed of the grid bars, reducing the impact force between the grid bars, and preventing damage caused by mutual impact between the grid bars.

[0008] Preferably, a sliding groove is provided on the arc-shaped plate, and a sliding part adapted to the sliding groove is provided at the bottom end of the elastic piece. The freedom degree of the sliding part is restricted by the sliding groove, so that the elastic piece can only move back and forth relative to the arc-shaped plate.

[0009] Preferably, an easily breakable part is provided in the middle of the arc-shaped plate. The easily breakable part divides the elastic piece into upper and lower parts. A protruding part protruding above the easily breakable part is provided on the lower part. The elastic band is connected to the protruding part. When the grid bars are scattered, the fracture of the steel belt moves to both sides, and the two arc-shaped plates are separated from each other. The elastic band applies a pulling force to the arc-shaped plates, and the lower part of the arc-shaped plate bends towards its concave surface direction, so that the lower part of the arc-shaped plate closely adheres to the lower part of the grid bars, thereby avoiding the arc-shaped plates from detaching from the grid bars and being able to prevent the grid bars from rolling down too fast.

[0010] Preferably, one end of each of the two arc-shaped plates close to each other is adhesively bonded. When the two arc-shaped plates are subjected to a large tensile force, the tensile force causes a tendency for them to separate, resulting in the disconnection of the connection between the two arc-shaped plates and thus their separation from each other.

[0011] Preferably, a tapered block for positioning between two grid bars is provided at the bottom end of the arc-shaped plate, enabling the arc-shaped plate to be better stuck on the second-layer grid bar and preventing the arc-shaped plate from shifting when the first-layer grid bar is placed and the grid bar comes into contact with the elastic sheet.

[0012] Preferably, the conveying device includes a plurality of conveying rollers arranged in an array in the front-rear direction. The bundling device is installed between the conveying rollers, and the conveying rollers are divided into a front roller group and a rear roller group with the bundling device as the boundary. The grid bars are stacked on the rear roller group and then conveyed forward to the front roller group. During this process, the bundling device bundles the grid bar stack with steel straps at intervals.

[0013] Preferably, a material blocking device for keeping the shape of the grid bar stack is installed between the conveying rollers of the front roller group. The material blocking device stacks the grid bars into a certain shape, thus facilitating subsequent bundling and transportation.

[0014] Preferably, the material blocking device includes multiple pairs of material blocking rollers respectively arranged between the conveying rollers. Each pair of material blocking rollers is symmetrically arranged, and an included angle of 60° is formed between the material blocking rollers and the conveying rollers, enabling the grid bar stack to be stacked between the material blocking rollers and approximately forming a hexagon in the front view projection plane.

[0015] Preferably, the material blocking device further includes an adjusting device for adjusting the distance between each pair of material blocking rollers. The distance between the material blocking rollers is adjusted through the adjusting device to adapt to different situations.

[0016] Preferably, the adjusting device includes a driving seat arranged in the left-right direction. The bottom end of the material blocking roller is slidably installed on the driving seat. The driving seat is used to drive each pair of material blocking rollers to approach or move away from each other. The driving seat makes the two material blocking rollers approach or move away from each other to adjust the distance between them to adapt to grid bars of different sizes or different stacking quantities.

[0017] Adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0018] When stacking grid bars, first place a fixing member between the first layer and the second layer of grid bars. Subsequently, according to the layout of the arc-shaped plate, fasten the steel belt at a suitable position. Then, move the card slot to nest one side of the connection of the steel belt. When disassembling, cut the steel belt loop from the other side of the connection of the steel belt. Each pair of adjacent steel belts is connected by an arc-shaped plate and an elastic belt. Once the grid bars are scattered, the breaking point of the steel belt will move to both sides, and the lower half of the arc-shaped plate will bend towards its concave direction to ensure that the arc-shaped plate does not break away from the grid bars. When the stack of grid bars collapses, the elastic belt will be stretched until its elastic limit and finally break. At this time, when the collapse of the stack of grid bars tends to be stable, there is no need to cut the elastic belt additionally, and it effectively prevents the grid bars from rolling over a long distance.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Embodiments of the present invention will be described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] As Figures 1-7 shown, a grid bar packaging device includes a conveying device 1, a bundling device 2, and a plurality of fixing members 3. The grid bars are stacked on the conveying device 1 by a hoisting device, with the two ends of the grid bars aligned, and the grid bars are stacked to form an approximately hexagonal prism shape. After stacking to the second layer from top to bottom as preset, the fixing member 3 is placed above the two grid bars in the middle (which can be placed manually, preferably automatically by a mechanical gripper). After placement, the hoisting device hoists the last layer of grid bars onto the second layer of grid bars, so that the fixing member 3 is fixed between the grid bars.

[0031] The conveying device 1 includes: a plurality of conveying rollers 11, a mounting frame 12, and a material blocking device. The conveying rollers 11 are rotatably mounted on the mounting frame 12, and some of the conveying rollers 11 are connected with a driving device for their self-rotation (such as a sprocket and chain mechanism, where the sprocket is connected to the conveying roller 11, the chain meshes with the sprocket, and the driving shaft of the rotary driving source is the sprocket shaft, so that the chain meshes with the driving shaft of the rotary driving source. By starting the rotary driving source, the chain drives the sprocket to rotate, thereby rotating the conveying roller 11 to convey the grid bars, which are not shown in the figure), so as to make the stack of grid bars move in the front-rear direction. The mounting frame 12 is arranged in the front-rear direction, and a plurality of tie rods for enhancing the strength of the mounting frame 12 are fixedly installed between the left and right sides of the mounting frame 12. The plurality of conveying rollers 11 are divided into a front roller group and a rear roller group. The material blocking device is installed between the rear roller group and is used to keep the stack of grid bars in an approximately hexagonal shape. The grid bars are stacked on the rear roller group and are conveyed forward to the front roller group after stacking.

[0032] The material blocking device includes a plurality of pairs of material blocking rollers 13 and an adjusting device 14. Every two material blocking rollers 13 form a pair and are symmetrically arranged left and right. The material blocking rollers 13 form a 60° angle with the conveying rollers 11. Therefore, the angle between each pair of material blocking rollers 13 is 60°, so that the stack of grid bars is stacked between the material blocking rollers 13 and is approximately hexagonal in the front view projection plane. The adjusting device 14 is used to adjust the distance between each pair of material blocking rollers 13 to adapt to grid bars of different sizes.

[0033] The adjusting device 14 includes a driving seat. The bottom end of the material baffle roller 13 is slidably installed on the driving seat. A bidirectional lead screw is installed in the driving seat. The bidirectional lead screw has two threads with opposite helix directions, and are respectively located on the left and right parts (not shown in the figure). The bottom ends of a pair of material baffle rollers 13 are respectively engaged with the two threads. One end of the lead screw is installed with a motor (not shown in the figure) for driving its rotation. When the motor is started, the output end of the motor drives the bidirectional lead screw to rotate. Since the material baffle roller 13 is slidably connected to the driving seat, the rotational freedom of the material baffle roller 13 is restricted. In this way, the rotational motion of the bidirectional lead screw is converted into a linear motion for controlling the material baffle roller 13 in the left and right directions, so that the two material baffle rollers 13 approach or move away from each other, and the distance between them is adjusted to adapt to grid frame bars of different sizes or different stacking quantities.

[0034] The bundling device 2 is arranged between the front roller group and the rear roller group. When the stack of grid frame bars moves forward and passes through the bundling device 2, the bundling device 2 unwinds the steel belt 21, so that the steel belt 21 winds around the stack of grid frame bars for one circle, forming an overlapping part above the stack of grid frame bars. Then the steel belt 21 is tightened, and then the overlapping part of the steel belt 21 is fixed together (it can be fixed by steel belt buckles, welding or riveting, preferably by riveting). Every time the stack of grid frame bars moves forward a certain distance, two circles of steel belts 21 are fixed to form a steel belt group, and there is a certain distance between the two circles of steel belts 21.

[0035] The fixing parts 3 correspond to the steel belt groups one by one. The fixing part 3 includes two arc-shaped plates 31, two elastic pieces 32 and an elastic belt 33. The radian of the arc-shaped plate 31 is the same as the outer radian of the grid frame bar, so that the arc-shaped plate 31 can be closely attached to the grid frame bar. The orientations of the two arc-shaped plates 31 are different. The arc-shaped plate 31 on the left has its concave surface facing left. The arc-shaped plate 31 on the right has its concave surface facing right. The two arc-shaped plates 31 are staggered in the front and rear directions, and the staggering distance is equal to the staggering distance between the two steel belts 21 in the steel belt group. The two arc-shaped plates 31 can be detachably connected (for example: attracted to each other by magnetism, engaged by a clamping groove, adhered by an adhesive substance, preferably adhered, with lower cost). When the two arc-shaped plates 31 are subjected to a large force that separates the two, the connection between the two arc-shaped plates 31 is disconnected, so that they are separated from each other. A recessed part is formed at the bottom of the two arc-shaped plates 31 for being placed on the grid frame bar in the middle of the second layer. The bottom ends of the two arc-shaped plates 31 respectively abut against the adjacent two grid frame bars, so that the fixing part 3 is positioned in the middle of the second layer. Then the grid frame bars of the first layer are stacked on top, so that the fixing part 3 is fixed between the grid frame bars;

[0036] The material of the elastic piece 32 is elastic metal (such as spring steel). The two elastic pieces 32 are respectively slidably mounted on the two arc-shaped plates 31 and are respectively located on the left and right sides of the two arcs. Therefore, in the front view projection plane, the two elastic pieces are symmetrical left and right. A through chute 311 is formed in the arc-shaped plate 31 in the left-right direction. A U-shaped sliding part 321 that cooperates with the chute 311 is arranged at the bottom of the elastic piece, so that the sliding part 321 can slide back and forth along the chute 311. In order to make the sliding part 321 located at the front end of the chute 311 in the initial state and prevent the sliding part 321 from sliding forward again after sliding to the rear end of the chute 311, a check structure is arranged in the chute 311. When the fixing pieces 3 are placed at equal intervals in the middle position above the second-layer grid bars, the top ends of the elastic pieces 32 are located exactly in the middle above the second-layer grid bars, so that when placing the first-layer grid bars, the grid bars can be prevented from pressing on the elastic pieces 32;

[0037] The check structure is an elastic protrusion 3111 arranged in the chute 311 and inclined backward. The elastic protrusion 3111 is a piece punched and cut from the middle top wall of the chute 311 and is inclined backward and downward. When the sliding part 321 is located at the front end of the chute 311, the rear end of the sliding part 321 contacts the elastic protrusion 3111, and the elastic protrusion 3111 hinders the sliding part 321 from sliding backward in the chute 311. When a backward sliding force is applied to the sliding part 321, the elastic protrusion 3111 retracts, and the sliding part 321 slides over the elastic protrusion 3111 to the rear end of the chute 311. Finally, the elastic protrusion 3111 pops out, and the rear end of the elastic protrusion 3111 abuts against the front end of the sliding part 321, thereby preventing the sliding part 321 from sliding forward in the chute 311;

[0038] A clamping groove 322 is arranged at the upper part of the elastic piece 32. The clamping groove 322 is open at the left, right and rear ends, and the height of the clamping groove 322 is the same as the thickness of the steel strip 21, so that the clamping groove 322 can slide backward and be clamped on the steel strip 21. The clamping grooves 322 of the two elastic pieces 32 belonging to the same fixing piece 3 are respectively clamped on the two steel strips 21 of the steel strip group, and the two clamping grooves 322 are respectively located on the left and right sides of the joint of the steel strip 21. That is, when one clamping groove 322 is clamped on the left side of the joint of one steel strip 21, the other clamping groove 322 is clamped on the right side of the joint of the other steel strip 21;

[0039] A cutting groove 312 extending in the front-rear direction is formed in the middle position of the arc-shaped plate 31. The rear end of the cutting groove 312 penetrates through the rear end of the arc-shaped plate 31, and the front end of the cutting groove 312 is located in the middle of the arc-shaped plate 31. A strip-shaped breakable portion 313 is arranged in the front-rear direction between the front end of the cutting groove 312 and the front end of the arc-shaped plate 31, so that the middle part of the arc-shaped plate 31 is prone to deformation. The breakable portion 313 divides the arc-shaped plate 31 into upper and lower parts, and a convex portion 314 protruding above the breakable portion 313 is arranged on the lower part of the arc-shaped plate 31. The convex portion 314 is not connected to the upper part of the arc-shaped plate 31. Thus, when the convex portion 314 is subjected to a tensile force, the lower part of the arc-shaped plate 31 rotates towards the direction of its concave surface;

[0040] In order to enable the arc-shaped plate 31 to be more stably clamped on the second-layer grid bars, a tapered block 315 for positioning is arranged at the bottom end of the arc-shaped plate 31 between two grid bars. The left and right side surfaces of the tapered block 315 are both arc-shaped and can be attached to the second-layer grid bars, so that the arc-shaped plate 31 can be better clamped on the second-layer grid bars, avoiding the contact between the grid bars and the elastic sheet 32 when placing the first-layer grid bars, which may cause the arc-shaped sheet to shift.

[0041] The elastic band 33 is made of rubber. The two ends of the elastic band 33 are respectively connected to the top ends of the convex portions 314 on the two elastic sheets 32. Thus, when the spring is tightened and stretched, the elastic band 33 applies a tensile force to the convex portion 314, so that the lower part of the elastic sheet 32 rotates towards the direction of its concave surface. Let the bottom side length of the hexagon formed by the steel strip 21 be x, and when the elastic band 33 is stretched to 0.7x - x, the elastic band 33 breaks. Therefore, when disassembling the grid bars, cut the side of all the connections of the steel strip 21 away from the card slot 322. The upper grid bars roll to both sides. At this time, one side of the slot abuts against the connection of the steel strip 21. Therefore, the card slot 322 cannot be separated from the steel strip 21. When the cut end of the steel strip 21 moves to both sides, the elastic band 33 is stretched, thus preventing the arc-shaped plate 31 from detaching from the grid bars (as Figure 8 shown). Before the grid bar stack completely collapses, the elastic band 33 is stretched beyond the elastic limit and the elastic band 33 breaks. Therefore, there is no need to separately cut the elastic band 33, and it can prevent the grid bars from rolling to a relatively far position.

[0042] The working steps of the packaging equipment are as follows:

[0043] Step 1: Start the motor to control the rotation of the lead screw. The rotational motion of the bidirectional lead screw is converted into the linear motion of the control material retaining roller 13 in the left-right direction, so that the two material retaining rollers 13 approach or move away from each other, and the distance between them is adjusted to adapt to the size and quantity of the stacked grid bars;

[0044] Step 2: Use a hoisting device to install the grid bars on the conveying device 1 until the second layer of grid bars is completely installed, and stack the grid bars between the material retaining rollers 13, which is approximately hexagonal in the front view projection plane.

[0045] Step 3: Place multiple fixing parts 3 at equal intervals by means of automated equipment or manually, so that the fixing parts 3 are placed at the middle position above the second layer of grid bars, and insert the conical blocks 315 into the gaps between the second layer of grid bars, so that the arc plates 31 can be better stuck on the second layer of grid bars, avoiding the contact between the grid bars and the elastic pieces 32 when placing the first layer of grid bars, which may cause the arc pieces to shift.

[0046] Step 4: Use the device to place the first layer of grid bars on the second layer of grid bars. At this time, the first layer of grid bars and the second layer of grid bars press the lower part of the arc plate 31, so that the arc plate 31 is fixed between the first layer of grid bars and the second layer of grid bars.

[0047] Step 5: Convey the stack of grid bars forward and stop when the arc plate 31 passes through the bundling device 2.

[0048] Step 6: The bundling device 2 winds a steel belt 21 around the stack of grid bars, fixes the two ends of the steel belt 21, and the connection of the steel belt 21 is located at the middle position of the top of the grid bars. In this way, until multiple steel belts 21 corresponding to the number of arc plates 31 are fixed.

[0049] Step 7: Manually move all the elastic pieces 32 so that the corresponding steel belts 21 move, and make the card slots 322 face the steel belts 21, and make the card slots 322 stuck on the steel belts 21 to complete the bundling work of the stack of grid bars.

[0050] When the grid bars are transported to the destination and the steel belt 21 needs to be disassembled, the steps are as follows:

[0051] Step 8: Place the stack of grid bars on the ground or a flat surface.

[0052] Step 9: Use a cutting device to cut off the side of all the connections of the steel belts 21 away from the card slots 322 in sequence.

[0053] Step 10: The upper grid bars roll to both sides. At this time, one side of the groove abuts against the connection of the steel belt 21, so the card slot 322 cannot be separated from the steel belt 21. When the cut-off ends of the steel belt 21 move to both sides, the two arc plates 31 are separated from each other, and the elastic band 33 pulls the arc plates 31, and the lower part of the arc plates 31 bends towards the concave surface direction, thus avoiding the arc plates 31 from detaching from the grid bars and being able to prevent the grid bars from rolling down too fast.

[0054] Step 11: When the upper grid bars fall to the lower part, the elastic band 33 is stretched beyond the limit and breaks, so there is no need to cut the elastic band 33 anymore, and it can prevent the grid bars from scattering too far away.

[0055] In summary, when stacking the grid bars, place the fixing member 3 between the first layer of grid bars and the second layer of grid bars, then tie the corresponding steel belt 21 according to the position of the arc plate 31. After that, push the card slot 322 so that the card slot 322 is stuck on one side of the connection of the steel belt 21. When untying the steel belt 21, cut the steel belt 21 loop from the other side of the connection of the steel belt 21. The two adjacent steel belts 21 are connected by the arc plate 31 and the elastic belt 33. Therefore, when the grid bars are scattered, the fracture of the steel belt 21 moves to both sides, and the lower part of the arc plate 31 bends towards its concave surface direction, thus preventing the arc plate 31 from detaching from the grid bars. When the grid bar stack collapses, the elastic belt 33 is stretched until the elastic belt 33 is stretched beyond the elastic limit and the elastic belt 33 breaks. At this time, the grid bar stack is basically completely collapsed. Therefore, there is no need to cut the elastic belt 33 separately, and it can prevent the grid bars from rolling to a farther position.

[0056] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
