Description

Technical Field

[0001] The invention belongs to the field of truss processing, and particularly relates to a full-automatic disassembly-free truss screw assembly machine. Background Art

[0002] A truss is a structure composed of members connected at both ends by hinges. Common trusses are typically composed of straight rods, typically triangular units, forming a planar or spatial structure. Truss members primarily bear axial tension or compression, fully utilizing the material's strength. For larger spans, this can save material, reduce weight, and increase stiffness compared to solid beams. Trusses are typically fabricated into wall panels by welding feet to their base, then casting the structure, and finally removing the feet. A new type of non-detachable truss exists that retains its base structure after casting. This base structure, rather than a traditional footing, serves as a base formwork. Currently, the most common base formwork consists of three layers: galvanized sheet metal, sponge board, and cement fiber board, from top to bottom. Because this type of non-detachable truss has only recently been around, specialized processing equipment is not available. Currently, base formwork fabrication is typically performed manually using outdated equipment. For example, the sheets are manually positioned, then punched using a punch, and finally screwed with screws. This production method is inefficient and will inevitably fall short of meeting the expected high demand for this type of non-detachable truss. Summary of the Invention

DETAILED DESCRIPTION

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] Example

[0022] like Figure 1-Figure 5 As shown, the embodiment is sequentially connected with a main feed track 1, a punching and locking wire device 2, a main discharge track 3, an auxiliary feed track 4 located beside and parallel to the main feed track 1, and an auxiliary discharge track 5 located beside and parallel to the main discharge track 3. A transfer device 6 is provided above the main feed track 1 and the auxiliary feed track 4. In simple terms, the main feed track 1 is used to transport sponge boards and galvanized sheets, and the auxiliary feed track 4 is used to transport cement fiber boards. The function of the transfer device 6 is to transfer the cement fiber boards on the auxiliary feed track 4 to the sponge boards and galvanized sheets that have been placed on the main feed track 1 in advance, so that the three are in a fixed placement state and transported to the subsequent punching and locking wire device 2 for punching and locking to complete fixation.

[0023] like Figure 1-Figure 2 As shown, the transfer device 6 includes a transfer frame 61 mounted above the main feed track 1 and the auxiliary feed track 4, a transfer slide 62 arranged on the transfer frame 61, a first lifting cylinder 63 installed on the transfer slide 62 and movable along the transfer slide 62, and a suction cup structure 64 fixed to the bottom of the first lifting cylinder 63 and movable in the vertical direction under the drive of the first lifting cylinder 63. The suction cup structure 64 is used to adsorb the cement fiber board. The moving path of the first lifting cylinder 63 on the transfer slide 62 passes above the main feed track 1 and above the auxiliary feed track 4 respectively. Specifically, the first lifting cylinder 63 moves along the transfer slide 62 to above the auxiliary feed track 4, and then drives the suction cup structure 64 to move downward until the suction cup structure 64 absorbs the cement fiber board that moves to the designated position along the auxiliary feed track 4. After the suction cup structure 64 rises with the cement fiber board to a preset height, the first lifting cylinder 63 moves along the transfer slide 62 to above the main feed track 1. At this time, the sponge board and the galvanized sheet have been placed on the main feed track 1 in the required order. The suction cup structure 64 moves downward until the cement fiber board sticks to the sponge board. The suction cup structure 64 stops working, releases the cement fiber board, and then rises. Finally, it moves back to above the auxiliary feed track 4 with the first lifting cylinder 63 to wait for the next cement fiber board.

[0024] like Figures 1-4As shown, the main feed track 1 is used to transport the sponge board and the galvanized sheet to the designated position, and after the transfer device 6 transfers the cement fiber board to the top of the sponge board and the galvanized sheet, the three are output to the punching and locking wire device 2 at one end of the main feed track 1 in the order of galvanized sheet at the bottom and cement fiber board at the top for subsequent processing. A limiting device is provided below the main feed track 1, and the limiting device includes a first slide rail 12 fixed below the main feed track 1 and in the same direction as the main feed track 1, a limiting base 13 provided on the first slide rail 12 and movable along the first slide rail 12, and a plurality of limiting clamps 10 are provided on the limiting base 13. The function of the limiting clamp 10 is to align the cement fiber board, sponge board and galvanized sheet in the left-right direction to prevent misalignment that causes the finished product to need to be cut when in use. The limiting fixture 10 includes a limiting platform 14 fixed on a limiting base 13 and located below the main feed track 1, a group of second slide rails 15 provided at both ends of the limiting platform 14 and located on both sides of the main feed track 1, and a limiting block 16 is provided on the second slide rail 15, the upper half of which passes through the main feed track 1 and is located above the main feed track 1. The limiting block 16 can move along the second slide rail 15 to change the distance between it and the main feed track 1. Specifically, before the cement fiber board, sponge board, and galvanized sheet are placed on the main feed track 1, the limiting block 16 moves along the second slide rail 15 until the distance between it and the main feed track 1 reaches the maximum. After the cement fiber board, sponge board, and galvanized sheet are placed, the limiting block 16 moves along the second slide rail 15 toward the main feed track 1 until one side thereof is in contact with the outer side of the cement fiber board, sponge board, and galvanized sheet, so that the cement fiber board, sponge board, and galvanized sheet are aligned in the left-right direction.

[0025] like Figures 1-4 As shown, in the same limiting clamp 10, a lifting block 17 is provided at the top of one of the limiting blocks 16. The lifting block 17 is connected to a second lifting cylinder 18 provided on the back side of the limiting block 16. The lifting block 17 can change its vertical height under the drive of the second lifting cylinder 18. Specifically, before the limiting blocks 16 are clamped, the lifting block 17 can be driven by the second lifting cylinder 18 to rise until the distance between it and the top of the limiting block 16 where it is located reaches the maximum. When the limiting blocks 16 are clamped, the lifting block 17 moves downward until the bottom surface of the lifting block 17 contacts the upper surface of the cement fiber board. At this time, the lifting block 17 plays a role in limiting the plate materials placed on the main feed track 1 in the vertical direction, preventing these plate materials from bouncing during the early movement process.

[0026] like Figure 1 、 Figure 3As shown, the main feed track 1 is also provided with feed rails 81 located on both sides of the main feed track 1, and a first stepping device 82 that can move along the feed rails 81 is provided on several of the feed rails 81. The first stepping device 82 is used to clamp the plate to prevent the plate from being displaced in the vertical direction. The first stepping device 82 includes a stepping base 83 provided on the feed rails 81 and movable along the feed rails 81, a stepping rail 84 provided on the stepping base 83, a connecting platform 85 provided on the stepping rail and movable along the stepping rail 84 to change the distance between the main feed track 1, an upper clamping block 86 provided above the connecting platform 85 and capable of changing the vertical height, and a lower clamping block 87 provided on the stepping base 83 and capable of changing the vertical height. The upper clamping block 86 and the lower clamping block 87 can clamp the plate between them by changing in vertical height. Specifically, in the initial state, the connecting platform 85 moves on the stepping slide 84 to the end away from the main feeding track 1, the upper clamping block 86 moves upward to the upper end, and the lower clamping block 87 moves downward to the lower end. At this time, the distance between the upper clamping block 86 and the lower clamping block 87 reaches the maximum distance. When the transfer device 6 transfers the cement fiber board to above the sponge board and the galvanized sheet, the first stepping device 82 moves to the side of the plate along the feeding slide 81, and the plate is limited by the limit clamp 10. After the plate is aligned in the left and right directions, the connecting platform 85 moves on the stepping slide 84 toward the main feed track 1 until one side of the plate is located between the upper clamping block 86 and the lower clamping block 87 of the first stepping device 82, and the upper clamping block 86 and the lower clamping block 87 move toward the upper surface and the lower surface of the plate respectively until the upper clamping block 86 and the lower clamping block 87 clamp the plate. When all the first stepping devices 82 complete clamping, the first stepping device 82 moves along the feed slide 81 toward the punching and locking device 2, thereby carrying the plate toward the punching and locking device 2 until the plate enters the punching and locking device 2.

[0027] In this embodiment, the lower clamping block 87 is located directly below the upper clamping block 86 and has a tooth pattern 88 on the side facing the upper clamping block 86. The lower surface of the upper clamping block 86 also has a tooth pattern 88 corresponding to that of the lower clamping block 87. The tooth patterns 88 serve to enhance the friction between the upper and lower clamping blocks 86, 87, and the plate, preventing vibration and displacement of the plate during movement.

[0028] like Figure 1 、 Figure 5As shown, the punching and locking wire device 2 is arranged at one end of the main feed track 1. Its function is to punch holes in the plates transported into the punching and locking wire device 2 along the main feed track 1 and lock the plates with screws, so that they become the bottom template that can be directly used in the subsequent non-disassembly truss production. The punching and locking wire device 2 includes a body 21 arranged at one end of the main feed track 1, a processing track 22 arranged in the body 21 and corresponding to the main feed track 1, a processing slide 23 arranged on both sides of the processing track 22, a plurality of second stepping devices 89 arranged on the processing slide 23 and movable along the processing slide 23, a punching component and a locking wire component arranged directly above the processing track 22 and capable of changing the distance between the processing track 22 and the locking wire component under drive. The punching component is closer to the main feed track 1 than the locking wire component, that is, the plates are first punched by the punching component and then screwed by the locking wire component. Both the punching component and the locking wire component are structures that can be realized by the existing technology and will not be described in this embodiment. The positions of the punching components and the wire locking components on the plate are preset before processing, and the preset method can be controlled by an operating panel connected to the machine body 21. The structure of the aforementioned second stepping device 89 is the same as that of the first stepping device 82, and its function is also to clamp the plate on the processing track 22 to prevent the plate from being displaced due to vibration during the punching or wire locking process, resulting in deviation in the placement position. Specifically, when the plate enters the processing track 22 from one end of the main feed track 1, the second stepping device 89 moves to both sides of the plate. Before this, the second stepping device 89 is in the initial state (see the initial state of the first stepping device 82 for details). After the second stepping device 89 clamps the plate, the first stepping device 82 releases the plate, and then the second stepping device 89 moves the plate toward the punching component and the wire locking component to complete the subsequent punching and wire locking.

[0029] like Figure 1As shown, the main discharge track 3 is connected to the other end of the punching and locking wire device 2. The height of the main discharge track 3 corresponds to that of the processing track 22. A flipping device 7 is provided between the main discharge track 3 and the auxiliary discharge track 5. The function of the main discharge track 3 is to transport the bottom template that has been punched and locked with holes and wires output from the punching and locking wire device 2 to the flipping device 7. The flipping device 7 transfers the bottom template to the auxiliary discharge track 5 and flips the bottom template so that it is in a state that can be directly used later. The auxiliary discharge track 5 then transports the bottom template to the plate stacking location. The flipping device 7 includes a flipping base 71 provided between the main discharge track 3 and the auxiliary discharge track 5, flipping slides 72 provided at both ends of the flipping base 71, and a flipping shaft 73 provided on the flipping slide 72 and parallel to the main discharge track 3. The flipping shaft 73 can be driven to move along the flipping slide 72 to change the distance between the flipping shaft 73 and the main discharge track 3 and the auxiliary discharge track 5. A number of equally spaced limiting members 74 are fixed on the flip shaft 73, and limiting grooves 75 are provided in the limiting members 74. The limiting members 74 can rotate with the flip shaft 73 to the top of the main discharge track 3 or the auxiliary discharge track 5. Specifically, before the flip device 7 works on the fully automatic disassembly-free truss screw assembly machine, the limiting member 74 rotates with the flip shaft 73 to the side of the main discharge track 3, and at the same time, the flip shaft 73 moves on the flip slide 72 to the end away from the main discharge track 3. At this time, the limiting groove 75 faces the main discharge track 3; when the bottom template that has completed punching and locking the wire moves to the side of the flip device 7, the flip shaft 73 moves along the flip slide 72 toward the main discharge track 3. As the limiting member 74 approaches the bottom template, one side of the bottom template will enter the limiting groove 75. When the flip shaft 73 moves to one end close to the main discharge track 3, the limiting member 74 completes the limiting of the bottom template. Then the flip shaft 73 rotates, and the limiting member 74 rotates with the bottom template until the limiting member 74 rotates to the side of the auxiliary discharge track 5. Then the flip shaft 73 moves along the flip slide 72 toward the auxiliary discharge track 5 until the flip movement is away from the main discharge track 3. At this time, the bottom template is directly above the auxiliary discharge track 5. Finally, the flip shaft 73 moves on the flip slide 72 to the end away from the auxiliary discharge track 5. The bottom template falls off from the limiting groove 75 to the auxiliary discharge track 5, completing the transfer and flipping of the bottom template. In addition, the outer side of the limiting groove 75 is provided with an arc surface. The setting of the arc surface can prevent the limiting groove 75 from colliding when moving toward the bottom template, making it easier for the limiting groove 75 to clamp the bottom template.

[0030] It should be noted that, in the accompanying drawings of this embodiment, there are two flip shafts 73 , but in fact there is only one flip shaft 73 on the flip base 71 . The two flip shafts 73 are used in the accompanying drawings only to help readers understand the position changes of the flip shaft 73 in the two states on the main discharge track 3 or the auxiliary discharge track 5 .

[0031] In this embodiment, a number of evenly spaced stepping rollers are provided on the auxiliary feed track 4, the main discharging track 3, and the auxiliary discharging track 5. These stepping rollers can rotate to make the plates placed on the auxiliary feed track 4, the main discharging track 3 or the auxiliary discharging track 5 move in a specified direction, thereby ensuring the efficiency of the equipment during the processing.
