Description

Technical Field

[0001] The invention relates to the technical field of bundling equipment, and in particular to a grid rod packaging device. Background Art

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

[0003] A Chinese patent document with authorization announcement number CN107738773B discloses an automatic steel pipe bundling device, which relates to the technical field of steel pipe bundling, and includes a transport device for transporting steel pipes, a support device for supporting steel pipes, a bundling device arranged above the transport device, and a control device, wherein the control device is respectively connected to the transport 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 transport direction of the transport device. The automatic steel pipe bundling device provided in the patent document realizes that steel pipes stacked into a certain shape can be bundled in multiple passes in the length direction without moving by adopting a movable bundling device to move along the long axis direction of the steel pipe.

[0004] Existing pipe bundling devices usually use steel straps to wrap around one end of a pipe pile during bundling, then cut the steel straps, and then connect the ends of the steel straps by welding or snapping, so as to bundle the pipe pile. When the pipe pile needs to be disassembled, the pipes above have large gravitational potential energy, so after the steel straps are cut, the pipes collapse, which easily causes the pipes to roll a long distance. Therefore, the pipes need to be placed in an open area or on a professional support frame to prevent the pipes from colliding with other objects, causing damage to the pipes or other equipment. In summary, when removing the steel straps, a suitable area or professional equipment is required, so there are greater restrictions on removing the steel straps. Summary of the invention

[0005] The present invention provides a grid rod packaging device, aiming to solve the problem in the related art that when the pipes are disassembled and stacked on steel strips, the pipes will roll a long distance.

[0006] A grid rod packaging device comprises a conveying device for conveying a grid rod pile, a bundling device for bundling steel strips on the grid rod pile, and a plurality of fixing members arranged between a first layer of grid rods and a second layer of grid rods, wherein the fixing members comprise two arc-shaped plates staggered front and back and facing in different directions, the curvature of the arc-shaped plates being adapted to the grid rods, the two arc-shaped plates being detachably connected, and an elastic strip being connected between the two arc-shaped plates, an elastic sheet being slidably mounted on the top of the arc-shaped plates, a clamping groove being arranged on the upper part of the elastic sheet, the left, right and rear end of the clamping groove being open, and the height of the clamping groove being the same as the thickness of the steel strip, a non-return structure being arranged between the elastic sheet and the arc-shaped plates, for preventing the elastic sheet from sliding in the opposite direction after the clamping groove is stuck on the steel strip, and in the initial state, on the front projection plane, the top ends of the two elastic sheets are both located in the upper middle part of the grid rod pile, and after the steel strips are bundled, the clamping grooves on the two elastic sheets are respectively stuck on two adjacent steel strips, and are respectively located on the left and right sides of the connection of the steel strips.

[0007] The effect is that: in the process of stacking the grid poles, when the second layer is stacked, the fixing parts are installed on the second layer of grid poles, and then the first layer of grid poles are placed, so that the arc plate is fixed between the first layer and the second layer of grid poles, and then according to the position of the arc plate, the steel belt is fastened and tied to the grid pole pile at a suitable position by using the binding device, and finally the card slot is clamped on the steel belt, so that the fixing parts and the steel belt are connected together, and when the grid pole pile moves to the destination, the grid pole pile is placed on the ground, and then cut. The connection of the broken steel belt is away from one end of the card slot, and two adjacent cut steel belts are connected by elastic parts, arc plates and elastic belts. When the grid rod pile collapses, the broken part of the steel belt moves to both sides, thereby stretching the elastic belt to deform and elongate the elastic belt, thereby limiting the position of the arc plate, making the arc plate close to the hooked grid rod, avoiding the arc plate from falling off, thereby limiting the rolling range of the grid rod, and at the same time reducing the speed of grid rod collapse, reducing the impact force between the grid rods, and avoiding damage caused by collision between the grid rods.

[0008] Preferably, a slide groove is provided on the arc plate, and a sliding part matched with the slide groove is provided at the bottom end of the elastic sheet, and the slide groove limits the freedom of the sliding part so that the elastic sheet can only move forward and backward relative to the arc plate.

[0009] Preferably, an easy-folding portion is provided in the middle of the arc-shaped plate, and the easy-folding portion divides the elastic sheet into two parts, an upper and lower part. A protrusion protruding to the top of the easy-folding portion is provided on the lower part, and the elastic belt is connected to the protrusion. When the grid rods are scattered, the broken part of the steel belt moves to both sides, and the two arc-shaped plates are separated from each other. The elastic belt applies a pulling force to the arc-shaped plate, and the lower part of the arc-shaped plate is bent toward its concave direction, so that the lower part of the arc-shaped plate is close to the lower part of the grid rod, thereby preventing the arc-shaped plate from detaching from the grid rod and preventing the grid rod from rolling down too fast.

[0010] Preferably, the two arc-shaped plates are bonded to each other at their ends that are close to each other. When the two arc-shaped plates are subjected to a large tensile force, the tensile force causes the two arc-shaped plates to have a tendency to separate, thereby disconnecting the connection between the two arc-shaped plates and separating them from each other.

[0011] Preferably, a conical block for positioning between two grid rods is provided at the bottom end of the arc plate, so that the arc plate can be better stuck on the second layer of grid rods, avoiding displacement of the arc plate due to contact between the grid rods and the elastic sheet when the first layer of grid rods are placed.

[0012] Preferably, the conveying device includes a plurality of conveying rollers arranged in an array along the front-to-back 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 rods are stacked on the rear roller group, and after stacking is completed, they are conveyed forward to the front roller group, and during this process, the bundling device bundles the grid rod stack with steel belts at intervals.

[0013] Preferably, a material blocking device for keeping the shape of the grid rod stack is installed between the conveying rollers of the front roller group. The material blocking device allows the grid rod stack to be stacked into a certain shape, thereby 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 are symmetrically arranged, and a 60° angle is formed between the material blocking rollers and the conveying rollers, so that the grid rods are stacked between the material blocking rollers, and are approximately hexagonal on the front projection plane.

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

[0016] Preferably, the adjustment device includes a driving seat arranged along the left and right directions, and the bottom end of the material blocking roller is slidably mounted on the driving seat. The driving seat is used to drive each pair of material blocking rollers to move closer to or away from each other. The driving seat makes the two material blocking rollers move closer to or away from each other and adjusts the distance between them to adapt to grid rods of different sizes or different stacking numbers.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are as follows: When stacking the grid poles, firstly, the fixing parts are placed between the first and second layers of grid poles, and then the steel belt is fastened in the appropriate position according to the layout of the arc plate, and then the slot is moved to nest one side of the steel belt connection. When disassembling, the steel belt loop is cut from the other side of the steel belt connection. Each pair of adjacent steel belts is connected by the arc plate and the elastic belt. Once the grid poles are scattered, the breaking point of the steel belt will move to both sides, and the lower part of the arc plate will bend in the direction of its concave, so as to ensure that the arc plate will not be separated from the grid poles. When the grid pole pile collapses, the elastic belt will be stretched to its elastic limit and finally break. At this time, when the grid pole pile collapses and tends to be stable, there is no need to cut the elastic belt additionally, and at the same time, the grid poles are effectively prevented from rolling over a long distance.

[0027] Embodiments of the present invention are 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 intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] like Figure 1-Figure 7 As shown, a grid rod packaging device includes a conveying device 1, a bundling device 2 and a plurality of fixing members 3. The grid rods are stacked on the conveying device 1 by a hoisting device, the two ends of the grid rods are aligned, and the grid rods are stacked to form a shape similar to a hexagonal prism. When the stacking reaches the preset second layer from the top to the bottom, the fixing members 3 are placed above between the two middle grid rods (can be placed manually, preferably automatically by a mechanical gripper). After the placement is completed, the hoisting device hoists the last layer of grid rods on the second layer of grid rods, so that the fixing members 3 are fixed between the grid rods.

[0029] 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 transmission device for self-rotation (for example, a sprocket chain mechanism, a sprocket is connected to the conveying roller 11, the chain is meshed with the sprocket, the driving shaft of the rotating driving source is the sprocket shaft, so that the chain is meshed with the driving shaft of the rotating driving source, and the rotating driving source is started to rotate the chain with the sprocket, so that the conveying roller 11 rotates to convey the grid rods, which are not shown in the figure), so as to make the grid rod pile move in the front-to-back direction, the mounting frame 12 is arranged in the front-to-back direction, and a plurality of pull rods for enhancing the strength of the mounting frame 12 are fixedly installed between the left and right sides of the mounting frame 12, and the plurality of conveying rollers 11 are divided into a front roller group and a rear roller group, and the material blocking device is installed between the rear roller group, so that the grid rod pile can maintain an approximately hexagonal shape, and the grid rods are stacked on the rear roller group, and after stacking, they are transported forward to the front roller group.

[0030] The material blocking device includes multiple pairs of material blocking rollers 13 and an adjusting device 14, wherein every two material blocking rollers 13 form a pair and are symmetrically arranged on the left and right. A 60° angle is formed between the material blocking rollers 13 and the conveying rollers 11, so that the angle between each pair of material blocking rollers 13 is 60°, so that the grid rods are stacked between the material blocking rollers 13, and are approximately hexagonal on the front projection plane. The adjusting device 14 is used to adjust the distance between each pair of material blocking rollers 13 to accommodate grid rods of different sizes.

[0031] The adjusting device 14 includes a driving seat, and the bottom end of the material blocking roller 13 is slidably mounted on the driving seat, and a bidirectional lead screw is installed in the driving seat. The bidirectional lead screw has two sections of threads with opposite rotation directions, and is respectively located on the left and right parts (not shown in the figure). The bottom ends of a pair of material blocking rollers 13 are respectively engaged with the two sections of threads, and one end of the lead screw is installed with a motor for driving it to rotate (not shown in the figure). The motor is started, and the output end of the motor drives the bidirectional lead screw to rotate. Since the material blocking roller 13 is slidably connected to the driving seat, the rotational freedom of the material blocking roller 13 is limited, thereby converting the rotational motion of the bidirectional lead screw into a linear motion in the left and right directions to control the material blocking roller 13, so that the two material blocking rollers 13 are moved closer or farther away from each other, and the distance between them is adjusted to adapt to grid rods of different sizes or different stacking numbers.

[0032] The bundling device 2 is arranged between the front roller group and the rear roller group. When the grid rod stack moves forward and passes through the bundling device 2, the bundling device 2 unwinds the steel belt 21, so that the steel belt 21 wraps around the grid rod stack once, forming an overlapping part above the grid rod stack, and then tightens the steel belt 21. Thereafter, the overlapping parts of the steel belt 21 are fixed together (they can be fixed by steel belt buckles, welding or riveting, preferably by riveting). Every time the grid rod stack moves forward a certain distance, two circles of steel belt 21 are fixed to form a steel belt group, and there is a certain distance between the two circles of steel belt 21.

[0033] The fixing part 3 corresponds to the steel belt group one by one. The fixing part 3 includes two arc plates 31, two elastic sheets 32 and an elastic belt 33. The curvature of the arc plate 31 is the same as the outer curvature of the truss rod, so that the arc plate 31 can be tightly attached to the truss rod. The two arc plates 31 have different orientations, and the concave surface of the arc plate 31 on the left side faces the left. The concave surface of the arc plate 31 located on the right side faces the right side, and the two arc plates 31 are staggered in the front-to-back direction, and the staggered distance is equal to the staggered distance of the two steel belts 21 in the steel belt group. The two arc plates 31 can be detachably connected (for example: by magnetic attraction, by snap-fitting through a slot, by bonding through an adhesive material, preferably bonding, which has a lower cost). When the two arc plates 31 are subjected to a large force that separates the two arc plates 31, the connection between the two arc plates 31 is disconnected, and thus they are separated from each other. A recessed portion is formed at the bottom of the two arc plates 31, which is used to be mounted on the grid rods in the middle of the second layer. The bottom ends of the two arc plates 31 are respectively against two adjacent grid rods, so that the fixing member 3 is positioned in the middle of the second layer, and then the grid rods of the first layer are stacked, so that the fixing member 3 is fixed between the grid rods; The elastic sheet 32 is made of elastic metal (such as spring steel). The two elastic sheets 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 sheets are symmetrical left and right. A through chute 311 is formed in the arc-shaped plate 31 in the left-right direction. The bottom of the elastic sheet is provided with a U-shaped sliding portion 321 that cooperates with the chute 311, so that the sliding portion 321 can slide back and forth along the chute 311. In order to make the sliding portion 321 located at the front end of the chute 311 in the initial state and prevent the sliding portion 321 from sliding forward again after sliding to the rear end of the chute 311, a check structure is provided in the chute 311. When the fixing members 3 are placed at equal intervals in the middle position above the second-layer grid bars, the top ends of the elastic sheets 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 sheets 32; The check structure is an elastic protrusion 3111 that is inclined backward in the chute 311. The elastic protrusion 3111 is a piece stamped and cut out from the middle top wall of the chute 311 and is inclined backward and downward. When the sliding portion 321 is located at the front end of the chute 311, the rear end of the sliding portion 321 contacts the elastic protrusion 3111, and the elastic protrusion 3111 hinders the sliding portion 321 from sliding backward in the chute 311. When a backward sliding force is applied to the sliding portion 321, the elastic protrusion 3111 retracts, and the sliding portion 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 portion 321, thereby preventing the sliding portion 321 from sliding forward in the chute 311; A card slot 322 is provided in the upper part of the elastic sheet 32. The left, right, and rear ends of the card slot 322 are open, and the height of the card slot 322 is the same as the thickness of the steel strip 21, so that the card slot 322 can slide backward and be stuck on the steel strip 21. The card slots 322 of the two elastic sheets 32 belonging to the same fixing member 3 are respectively stuck on the two steel strips 21 of the steel strip group, and the two card slots 322 are respectively located on the left and right sides of the connection of the steel strips 21. That is, when one card slot 322 is stuck on the left side of the connection of one steel strip 21, the other card slot 322 is stuck on the right side of the connection of the other steel strip 21; A cutting groove 312 is provided in the middle of the arc plate 31 along the front-to-back direction, the rear end of the cutting groove 312 passes through the rear end of the arc plate 31, the front end of the cutting groove 312 is located in the middle of the arc plate 31, and a strip-shaped easy-folding portion 313 is provided between the front end of the cutting groove 312 and the front end of the arc plate 31 and along the front-to-back direction, so that the middle of the arc plate 31 is easy to deform, and the easy-folding portion 313 divides the arc plate 31 into two parts, an upper and lower part, and a convex portion 314 protruding above the easy-folding portion 313 is provided on the lower part of the arc plate 31, and the convex portion 314 is not connected to the upper part of the arc plate 31, so that when the convex portion 314 is subjected to tension, the lower part of the arc plate 31 rotates toward its concave surface. In order to enable the arc plate 31 to be more stably stuck on the second layer of grid rods, a conical block 315 for positioning between the two grid rods is provided at the bottom end of the arc plate 31. The left and right sides of the conical block 315 are both arc-shaped and can be attached to the second layer of grid rods, so that the arc plate 31 can be better stuck on the second layer of grid rods, avoiding the grid rods and the elastic sheet 32 ​​from contacting and causing the arc sheet to shift when the first layer of grid rods are placed.

[0034] The elastic band 33 is made of rubber, and the two ends of the elastic band 33 are respectively connected to the top ends of the protrusions 314 on the two elastic sheets 32, so that when the spring is tightened and stretched, the elastic band 33 applies a pulling force to the protrusions 314, so that the lower part of the elastic sheet 32 ​​rotates toward its concave surface. Assume that the bottom side length of the hexagon formed by the steel belt 21 is x, and when the elastic band 33 is stretched to 0.7xx, the elastic band 33 breaks. Therefore, when the grid rods are disassembled, the side of the connection of all steel belts 21 away from the slot 322 is cut off, and the upper grid rods roll to both sides. At this time, one side of the slot is against the connection of the steel belt 21, so the slot 322 cannot be separated from the steel belt 21. When the cut end of the steel belt 21 moves to both sides, the elastic band 33 is stretched, thereby preventing the arc plate 31 from being separated from the grid rod (such as Figure 8 As shown in the figure), before the grid rod pile completely collapses, the elastic band 33 is stretched to exceed the elastic limit and the elastic band 33 breaks. Therefore, there is no need to cut the elastic band 33 separately, and the grid rod can be prevented from rolling to a distant position.

[0035] The working steps of the packaging equipment are as follows: Step 1: Start the motor to control the screw to rotate, and the rotational motion of the bidirectional screw is converted into the linear motion of the material blocking roller 13 in the left and right directions, so that the two material blocking rollers 13 are moved closer or farther away from each other, and the distance between them is adjusted to adapt to the size and number of the stacked grid rods; Step 2: Install the grid rods on the conveying device 1 by means of a hoisting device until the second layer of grid rods is installed, so that the grid rods are stacked between the blocking rollers 13 and are approximately hexagonal in the front projection plane; Step 3: Place multiple fixing members 3 at equal intervals by automated equipment or manually, so that the fixing members 3 are placed in the middle position above the second-layer grid rods, and the conical blocks 315 are inserted into the gaps between the second-layer grid rods, so that the arc plates 31 can be better stuck on the second-layer grid rods, and avoid the grid rods and the elastic sheets 32 from contacting and causing the arc sheets to shift when the first-layer grid rods are placed; Step 4: Place the first layer of grid rods on the second layer of grid rods through the device. At this time, the first layer of grid rods and the second layer of grid rods press the lower part of the arc plate 31, so that the arc plate 31 is fixed between the first layer of grid rods and the second layer of grid rods; Step 5: convey the grid rod pile forward and stop when the curved plate 31 passes the bundling device 2; Step 6: The binding device 2 wraps a circle of steel belt 21 around the grid rod pile, so that the two ends of the steel belt 21 are fixed, and the connection of the steel belt 21 is located in the middle of the top of the grid rod, until a number of steel belts 21 corresponding to the number of arc plates 31 are fixed; Step 7: Manually move all the elastic sheets 32 to move the steel belt 21 corresponding to the elastic sheets 32, and make the card slots 322 face the steel belt 21, so that the card slots 322 are stuck on the steel belt 21, and the grid rod stack bundling work is completed; When the grid poles are transported to the destination and the steel belts 21 need to be disassembled, the steps are as follows: Step 8: Stack the grid poles on the ground or flat surface; Step 9: Use a cutting device to sequentially cut off the side of all the connections of the steel strips 21 away from the slot 322; Step 10: The upper grid rod rolls to both sides. At this time, one side of the groove abuts against the connection of the steel belt 21, so the slot 322 cannot be separated from the steel belt 21. When the cut end of the steel belt 21 moves to both sides, the two arc plates 31 separate from each other, and the elastic belt 33 pulls the arc plate 31, and the lower part of the arc plate 31 bends toward its concave surface, thereby preventing the arc plate 31 from separating from the grid rod and preventing the grid rod from rolling down too fast. Step 11: When the grid rods above are scattered to the bottom, the elastic band 33 is stretched beyond the limit and breaks, so there is no need to cut the elastic band 33, and the grid rods can be prevented from being scattered too far.

[0036] To sum up, when stacking the grid rods, the fixing member 3 is placed between the first layer of grid rods and the second layer of grid rods, and then the corresponding steel belt 21 is tied according to the position of the arc plate 31, and then the slot 322 is pushed so that the slot 322 is stuck on one side of the connection of the steel belt 21. When unbundling the steel belt 21, the steel belt 21 circle is cut from the other side of the connection of the steel belt 21. Two adjacent steel belts 21 are connected by the arc plate 31 and the elastic belt 33. Therefore, when the grid rods are scattered, the broken part of the steel belt 21 moves to both sides, and the lower part of the arc plate 31 is bent toward its concave direction, thereby preventing the arc plate 31 from detaching from the grid rods. When the grid rod pile 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 rod pile is basically completely collapsed, so there is no need to cut the elastic belt 33 separately, and the grid rods can be prevented from rolling to a farther position.

[0037] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
