Background Art

[0002] In today's automated pipe bending production line technology, common pipe bending machines can usually only produce and process serpentine bends of one specification and length, so they have gradually become unable to adapt to the development of contemporary society. Since most contemporary industries require that a pipe bending production line can produce serpentine bends of at least two specifications and lengths, engineers need to set different inlets at the feeding end of the pipe bending unit to distinguish pipes of different specifications. Therefore, a device must be set between the incoming roller and the feeding end of the pipe bending unit to automatically complete the transfer of pipe materials and automatically separate pipe materials of different specifications, and enter the subsequent pipe bending unit through different inlets. Therefore, it has become an inevitable trend for technicians in this field to develop a material separation and loading device. Summary of the Invention

[0022] The following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are intended to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention. That is, the present invention is not limited to the preferred embodiments described, and the scope of the present invention is defined by the claims.

[0023] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified, “perpendicular” and “parallel” do not just have absolute meanings in a mathematical sense, but can be understood as “approximately perpendicular” and “approximately parallel”.

[0024] Figure 1 It is a schematic diagram of the basic structure of the overall layout of an embodiment of the present invention.

[0025] Figure 2 It is a structural schematic diagram of the material distribution device f according to an embodiment of the present invention.

[0026] like Figure 1 and Figure 2As shown, this embodiment provides a device that can automatically transfer pipe materials between an incoming material conveyor and the feed end of a pipe bending unit, automatically sorting pipe materials of different specifications, and feeding them into subsequent pipe bending units through different entrances. This device improves upon a conventional chain-type feeding device by dividing it into a lifting device and a material sorting device. The lifting device and the material sorting device cooperate to complete the material sorting and loading of the pipe materials. A specific embodiment of the device structurally includes an inlet conveyor r and a base d, the inlet conveyor r being disposed adjacent to the base d. A lifting device t and a material sorting device f are also disposed on the base d. A first inlet r1 and a second inlet r2 are also disposed behind the material sorting device f, at two different heights. The inlet conveyor r is configured as a conventional material conveying device equipped with multiple rolling rollers, and the pipe-shaped material w is transported by the rolling of the rollers. The lifting device t is arranged vertically, and the material sorting device f is arranged horizontally. The lifting device t is configured as a sprocket structure, equipped with a driving pulley tzp, a driven pulley tcp, and a lifting chain tlp. The lifting chain tlp is externally mounted on the driving pulley tzp and the driven pulley tcp. The driving pulley tzp is positioned below, and the driven pulley tcp is positioned above. The driving pulley tzp actively rotates to drive the lifting chain tlp to rotate around the driving pulley tzp and the driven pulley tcp. The lifting device t is also equipped with lifting blocks tb extending outward from the outer surface of the lifting chain tlp. The lifting blocks tb are fixedly mounted on the outer side of the lifting chain tlp and are evenly distributed. The lifting blocks tb have an inclined surface q, and the angle formed between the inclined surface q and the adjacent outer surface of the lifting chain tlp is acute. This acute angle prevents the tubular material w from slipping outward when the lifting device t is transporting the tubular material w. In addition, preferably, the lifting device t can also be provided with a lifting tensioner tpp, and the lifting chain tlp can be outsourced to the lifting driving wheel tzp, the lifting driven wheel tcp and the lifting tensioner tpp. The lifting tensioner tpp can keep the lifting chain tlp in a taut state at all times without loosening.

[0027] The material distribution device f is configured as a sprocket structure, on which a material distribution driving wheel fzp, a material distribution driven wheel fcp and a material distribution chain flp are provided. The material distribution driving wheel fzp is provided at the first end of the material distribution device f, and the material distribution driven wheel fcp is provided at the second end of the material distribution device f. The material distribution chain flp is outsourced to the material distribution driving wheel fzp and the material distribution driven wheel fcp. The material distribution device f is further provided with a material distribution block fb extending outward along the outer surface of the material distribution chain flp. The material distribution block fb is fixedly provided on the outer side of the material distribution chain flp and multiple blocks are evenly distributed. Preferably, a telescopic device can be further provided between the material distribution driving wheel fzp and the material distribution driven wheel fcp. The telescopic device can realize the change of the mutual distance between the material distribution driving wheel fzp and the material distribution driven wheel fcp through a telescopic action. By changing the mutual distance between the material distribution driving wheel fzp and the material distribution driven wheel fcp, it is ensured that the material distribution chain flp is always in a taut state and does not relax.

[0028] The upper end of the lifting device t and the first end of the dividing device f overlap with each other on the transportation track of the tube-shaped material w. In this embodiment, preferably, the rotation center line of the lifting driven wheel tcp and the rotation center line of the dividing active wheel fzp are coaxial with each other, and the outer circle diameter of the lifting driven wheel tcp is the same as the outer circle diameter of the dividing active wheel fzp. In this way, the tube-shaped material w can be smoothly transferred from the lifting device t to the dividing device f, and the dividing and loading actions of the tube-shaped material w can be completed through the mutual cooperation of the lifting block tb and the dividing block fb.

[0030] Figure 4 This is a schematic diagram of feeding through the first feeding port r1 in an embodiment of the present invention.

[0031] Figure 5 It is a schematic structural diagram of the directional connecting rod fxp according to an embodiment of the present invention.

[0032] like Figure 3 、 Figure 4 and Figure 5As shown, according to one aspect of the specific implementation of an embodiment of the present invention, a splitter fx is further provided on the material dividing device f between the base d and the material dividing device f, and a splitter push cylinder fxt and a splitter connecting rod fxp are further provided on the splitter fx, and the splitter connecting rod fxp is respectively hinged to the splitter push cylinder fxt and the second end of the material dividing device f. The splitter connecting rod fxp is further provided with a splitter push rod fxpt, a splitter rocker fxpb and a splitter transmission shaft fxpc. Preferably, the splitter push rod fxpt is configured as a rod-shaped connecting rod, and its two ends are respectively hinged to the second end of the material dividing device f and the splitter rocker fxpb, and the splitter rocker fxpb is also configured as a rod-shaped connecting rod, and its two ends are respectively hinged to the splitter push rod fxpt and the base d. The split transmission shaft fxpc and the split swing arm fxpb are fixedly connected to each other, and the axis of the split transmission shaft fxpc is perpendicular to the plane in which the split swing arm fxpb swings, and the axis of the split transmission shaft fxpc is coaxial with the axis of the hinge axis that hinges the split swing arm fxpb to the base d. In this embodiment, the lifting device t, the material distribution device f, and the split connecting rod fxp provided on the base d are typically arranged in multiple groups in parallel directions, and the multiple groups of lifting devices t, material distribution devices f, and split connecting rods fxp operate synchronously to synchronously convey longer tubular materials w. The multiple parallel groups of split connecting rods fxp are connected end to end via the split transmission shaft fxpc. In this structure, only one split push cylinder fxt is required to achieve the synchronous operation of the multiple groups of split connecting rods fxp.

[0033] The telescopic rod of the directional push cylinder fxt is hinged to the hinge axis of the directional push rod fxpt and the directional swing arm fxpb, and the cylinder barrel of the directional push cylinder fxt is hinged to the base d. Under the action of this linkage mechanism, when the telescopic rod of the directional push cylinder fxt extends outward, the directional connecting rod fxp can push the distributing device f upward to the first feed inlet r1, allowing the tubular material w to enter the first feed inlet r1. When the telescopic rod of the directional push cylinder fxt retracts inward, the directional connecting rod fxp can pull the distributing device f downward to the second feed inlet r2, allowing the tubular material w to enter the second feed inlet r2. The directional push cylinder fxt can drive the directional connecting rod fxp to change the position at which the distributing device f discharges the tubular material w.

[0037] like Figure 6 、 Figure 7 and Figure 8 As shown, according to one aspect of a specific embodiment of the present invention, the lifting device t is further provided with a pusher tu, which is further provided with a push plate tub and a push cylinder tug. The pusher tu is arranged horizontally relative to the lifting device t and on the opposite side of the infeed roller r. The infeed roller r is further provided with a material storage trough cc above and outside the lifting device t. The push cylinder tug is capable of driving the pusher tub to push the tubular material w that has entered the lifting device t into the material storage trough cc. The pusher tub is configured as a swing arm structure, with its upper end hingedly connected to the upper end of the lifting device t. The telescopic lever of the pusher cylinder tug is hingedly connected to the lower end of the pusher tub, and the cylinder is hingedly connected to the base d. When the push cylinder tug telescopes, the pusher tub swings toward the tubular material w and pushes unqualified tubular material w that needs to be removed from the lifting device t into the material storage trough cc.
