DETAILED DESCRIPTION

[0028] The present invention provides a combined material receiving rack. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0029] See also Figure 1 The present invention provides a combined material receiving rack, comprising a plurality of material receiving mechanisms 10 arranged at intervals and a material receiving assembly 20 arranged between the material receiving mechanisms 10; see Figure 5 The plurality of material receiving mechanisms 10 each include a base 1, a movable plate 2 which is escalably disposed on the base 1, a lifting driving member 3 for driving the movable plate 2 to rise or fall, a material receiving plate 4 whose one end surface is rotatably connected to the upper portion of the movable plate 2, and a material receiving driving member 5 which is fixed to the movable plate 2 and is used to drive the material receiving plate 4 to tilt horizontally or downward; see Figure 2, the multiple material receiving components 20 all include a frame 6, a driving wheel 71 and a driven wheel 72 rotatably arranged on the frame 6, and a transport chain 73 wound between the driving wheel 71 and the driven wheel 72, a plurality of material limiting blocks 74 are arranged on the outer surface of the transport chain 73, and a material storage bayonet is formed between two adjacent material limiting blocks 74, and the driving wheels 71 on the multiple material receiving frames are connected by transmission shafts 75, and the transmission shafts 75 are connected by driving to the rotation drive device 8; the material receiving drive member 5 is used to transfer the pipes located on the material receiving plate 4 to the material storage bayonet located upstream, and the rotation drive device 8 is used to drive the transport chain 73 and the pipes in the material storage bayonet to be transported in the downstream direction.

[0030] Specifically, the driving wheel 71 is a first sprocket, and the driven wheel 72 is a second sprocket.

[0031] As shown in the figure, multiple material receiving components 20 and multiple material receiving mechanisms 10 are arranged at intervals and located in the material receiving area. The arranged multiple material receiving components 20 and multiple material receiving mechanisms 10 can start the corresponding material receiving mechanisms 10 and material receiving components 20 according to the length of the pipe. In actual application, the lifting drive member 3 drives the movable plate 2 to rise and fall with the pipe, thereby changing the height of the receiving plate 4 relative to the pipe (especially for non-round pipes). When the pipe needs to be supported, the receiving drive member 5 drives the receiving plate 4 to be in a horizontal state, and then the movable plate 2 and the receiving plate 4 move up and down; when the pipe needs to be unloaded, the receiving drive member 5 drives the receiving plate 4 to be in an inclined state, thereby guiding the pipe placed on the receiving plate 4 to the upstream position of the frame 6, in this embodiment, that is, to the position of the driven wheel 72. Since the storage bayonet provided on the transport chain 73 can be used to limit the movement of the pipe, as the pipe is unloaded, under the action of the rotating drive device 8, the driving wheel 71 and the driven wheel 72 are used to make the transport chain 73 rotate from the upstream direction to the downstream direction, so that the pipes on each storage bayonet can be transported one by one in the downstream direction. When the pipe is transported to the downstream end, wait for the pipe on the storage bayonet to be unloaded.

[0032] In the above arrangement, by separating the material receiving mechanism 10 and the material receiving assembly 20, the space occupied by the combined material receiving rack can be reduced, the manufacturing cost is low, and it is also convenient for shipment and transportation. Furthermore, by setting the lifting drive member 3, the movable plate 2 and the material receiving plate 4 can be lifted and lowered with movement, and the follow-up support can be realized; the material receiving drive member 5 is set, so that the material receiving plate 4 is used to support the pipe when it is horizontal, and is used for unloading the pipe when it is tilted downward; in addition, the material storage bayonet formed by the transport chain 73 and the material limiting block 74 is used to store the pipe, so as to avoid displacement of the pipe when the pipe is transported, and to realize smooth transportation and unloading of the pipe.

[0033] See also Figure 2In some embodiments, the frame 6 includes a crossbeam 61 parallel to the pipe conveying direction, a first vertical beam 62 fixedly connected to the lower surface of the crossbeam 61 in the upstream direction, and a second vertical beam 63 fixedly connected to the lower surface of the crossbeam 61 in the downstream direction; a plurality of the second vertical beams 63 are connected by a connecting rod 66; a fixing plate 613 is provided on the side wall in the upstream direction of the crossbeam 61, and the fixing plate 613 is used to fix the frame 6 to the side wall of the bed; a slot 611 is provided in the upstream direction of the crossbeam 61, and the driven wheel 72 is rotatably arranged in the slot 611. Specifically, a bottom plate 13 is also provided on the lower surface of the second vertical beam 63, and an adjusting foot cup is provided on the bottom plate 13. The waist-shaped holes on the fixing plate 613 are used to drive screws, so that the frame 6 is fixed to the side wall of the bed one by one, and installation and disassembly are very convenient. In addition, the cross beam 61, the first vertical beam 62 and the second vertical beam 63 are all made of square tubes, which are easy to obtain and low in cost. The slotted hole 611 is provided to provide an installation space for the driven wheel 72.

[0034] See also Figure 1 and Figure 2 In some embodiments, the slot 611 divides the crossbeam 61 into an extension section and a material receiving section; the extension section is located upstream of the slot 611, and the material receiving section is located downstream of the slot 611. As described above, a material receiving mechanism 10 is provided between the two material receiving assemblies 20, and the material receiving mechanism 10 is located upstream of the two material receiving assemblies 20. The purpose of providing the extension section is to enable the frame 6 to form a stable connection with the bed, and the pipe material received on the material receiving mechanism 10 is transferred to the upstream position of the transport chain 73 through the material receiving mechanism 10 and then transported.

[0035] See also Figure 2 In some embodiments, a reinforcing beam 64 is fixedly connected to the side wall of the first vertical beam 62. The reinforcing beam 64 is perpendicular to the extension direction of the cross beam 61, and the reinforcing beam 64 is used to fix the frame 6 to the reinforced side seat of the bed. In this embodiment, the upstream of the cross beam 61 forms a connection relationship with the bed, and the provided reinforcing beam 64 forms a connection relationship with the reinforced side seat on the bed again, thereby further strengthening the connection stability between the material receiving frame and the bed.

[0036] See also Figure 3In some embodiments, the driving wheel 71 is sleeved on the rotating shaft 711, the rotating shaft 711 is connected to the crossbeam 61 through two seat bearings 712, and one end of the rotating shaft 711 is connected to the transmission shaft 75 through a universal joint coupling 76. That is, when one of the rotating shafts 711 rotates, the power is transmitted to the other rotating shaft 711 through the universal joint coupling 76, the transmission shaft 75 and the universal joint coupling 76 in sequence. The universal joint coupling 76 can compensate for the misalignment problem caused by a certain angle deviation or displacement between the axes of the two rotating shafts 711, so that the two rotating shafts 711 can maintain mutual connection and transmit torque, reducing the strict requirements for axis pairing.

[0037] See also Figure 3 In some embodiments, the rotation drive device 8 includes a motor bracket 81, a driving motor 82 disposed on the motor bracket 81, a driving sprocket 83 disposed on the output end of the driving motor 82, a driven sprocket 84 sleeved on one of the rotating shafts 711, and a driving chain 85 wound between the driving sprocket 83 and the driven sprocket 84. When transporting pipes, the driving motor 82 drives the driving sprocket 83 to rotate, and under the transmission of the driving chain 85 and the driven sprocket 84, the rotating shaft 711 is driven to rotate, and then the driving wheel 71 on the rotating shaft 711 is driven to rotate, providing power for the transport chain 73.

[0038] See also Figure 4 In some embodiments, the driven wheel 72 is arranged on the adjustment support shaft 842 through a bearing 841, and a stop plane 8421 is provided on the circumferential wall at both ends of the adjustment support shaft 842, and a tightening threaded hole is provided on the stop plane 8421. A fixing block 843 is provided on each side surface of the crossbeam 61, and a tightening screw 844 matching with the tightening threaded hole passes through each fixing block 843, and the head of the tightening screw 844 presses against the fixing block 843 and the screw portion of the tightening screw 844 is connected with the tightening threaded hole. A tightening nut 845 is threadedly connected to the tightening screw 844, and the tightening nut 845 and the head of the tightening screw 844 clamp the fixing block 843 together. The cooperation between the tightening screw 844 and the tightening threaded hole allows the operator to adjust the position of the driven sprocket 84 by rotating the tightening nut 845, thereby finely adjusting the tension of the transport chain 73. This ensures that the transport chain 73 can maintain proper tension after long-term use, and avoids slipping caused by too loose transport chain 73 or extra wear caused by too tight transport chain 73.

[0039] See also Figure 4In some embodiments, the left and right side walls of the crossbeam 61 are respectively provided with U-shaped grooves 612 connected to the slot hole 611, and the two ends of the adjustment support shaft 842 pass through the corresponding U-shaped grooves 612; the left and right side walls of the crossbeam 61 are respectively provided with a second stop block 846 detachably, and the two second stop blocks 846 are both located above the ends of the adjustment support shaft 842. The upper part of the U-shaped groove 612 is designed to be open, so that the adjustment support shaft 842 can be easily placed into the U-shaped groove 612 and the slot hole 611 from top to bottom, which is convenient for installation. Then, the second stop block 846 is used to limit the movement of the upper part of the adjustment support shaft 842 to prevent the driven wheel 72 rotatably connected to the adjustment support shaft 842 from falling off from the slot hole 611.

[0040] See also Figure 3 In some embodiments, a limiting plate 65 is provided at the downstream end of the cross beam 61, and the limiting plate 65 is used to prevent the pipe from continuing to be transported downstream. The limiting plate 65 can prevent the pipe from sliding out of the receiving rack easily due to the inertia of the pipe moving downstream, so that the pipe is limited to the downstream end.

[0041] See also Figure 2 and Figure 3 In some embodiments, a stroke sensing mechanism 9 for sensing the pipe is also provided near the downstream end of the cross beam 61; the stroke sensing mechanism 9 includes a support plate 91 fixed on the side wall of the cross beam 61, a travel switch 92 provided on the support plate 91, and a material arrival pressure plate 93 provided on the output end of the travel switch 92. In order to automatically detect whether the pipe is transported to the set position, the stroke sensing mechanism 9 is provided. When the pipe triggers the stroke sensing mechanism 9, it means that the pipe is transported to the position. At this time, the stroke sensing mechanism 9 feeds back a signal to the control system, and the control system controls the rotation drive device 8 to stop working until the pipe is unloaded. The rotation drive device 8 restarts to realize the automatic material receiving and transportation of the next pipe. Specifically, when the pipe is transported to the position of the material arrival pressure plate 93, the material arrival pressure plate 93 is pressed down, triggering the travel switch 92, and the control system controls the rotation drive device 8 to stop the transportation of the pipe. After the pipe is unloaded and transferred to leave the rack 6, the rotation drive device 8 will run again.

[0042] See also Figure 3In some embodiments, a photoelectric sensor 94 is further provided upstream of the material arrival pressing plate 93 (the figure indicates a mounting plate of the photoelectric sensor 94), and a plurality of sensing sheets 95 corresponding to the material storage bayonet are fixedly connected to the transport chain 73, and the photoelectric sensor 94 is used to sense the sensing sheets 95. When the sensing sheets 95 pass the position of the photoelectric sensor 94, the transport chain 73 stops moving, and the material receiving mechanism 10 will transfer the next pipe on the receiving plate 4 to the upstream of the transport chain 73 after the pipe in the material storage bayonet at the downstream end of the transport chain 73 is unloaded.

[0043] See also Figure 1 In some embodiments, a receiving box 30 is provided next to the receiving frame near the laser cutting assembly, and the receiving box 30 is used to receive the tailings / short tubes. This position is within the cutting area, and the short tube receiving structure is used to support and receive the tailings / short tubes, so that the tailings / short tubes can be transferred to the receiving box 30 without being transported through the receiving assembly 20.

[0044] See also Figure 6 In some embodiments, the base 1 includes a plurality of vertical square tubes 11 arranged vertically, a plurality of horizontal square tubes 12 arranged horizontally, and a bottom plate 13; the plurality of horizontal square tubes 12 are used to connect the plurality of vertical square tubes 11, and the back of the bottom plate 13 is fixedly connected to the front of the vertical square tubes 11 and the horizontal square tubes 12. The frame structure composed of the vertical square tubes 11 and the horizontal square tubes 12 can ensure the stability of the base 1, and the base 1 can be made by welding a plurality of square tubes, which is convenient to obtain materials, has low manufacturing difficulty, and is lightweight.

[0045] See also Figure 6 In some embodiments, the vertical square tubes 11 are arranged in multiple groups in front and back, and a through hole 111 is provided on the side wall of the vertical square tube 11 at the rear, and a waist-shaped mounting hole 112 extending along its height direction is provided on the back of the vertical square tube 11 at the rear, and the waist-shaped mounting hole 112 is used to fix the base 1 on the bed. The multiple groups of vertical square tubes 11 can change the width of the base 1 in the front and back directions / upstream and downstream, so that the material receiving assembly 20 is more suitable for laser processing scenarios. The setting of the through hole 111 makes it easy to put the tool into the square tube, and drive the screws / bolts into the corresponding waist-shaped mounting holes 112, so as to realize the installation of the material receiving mechanism 10 on the bed. The setting of the waist-shaped mounting hole 112 can fine-tune the height position of the material receiving mechanism 10 relative to the bed, which is convenient for installation.

[0046] See also Figure 6In some embodiments, the lifting drive member 3 includes a lifting drive motor 8231, a transmission gear 32 connected to the output end of the lifting drive motor 8231, and a transmission rack 33 arranged on the front side of the bottom plate 13; the output end of the lifting drive motor 8231 passes through the front and rear side walls of the movable plate 2; the transmission rack 33 is vertically extended and arranged on the bottom plate 13; the transmission gear 32 is meshed with the transmission rack 33. When in use, when the lifting drive motor 8231 rotates forward, it drives the transmission gear 32 to rotate forward, and under the guidance of the transmission rack 33, the movable plate 2 and the receiving plate 4 are synchronously raised. On the contrary, when the lifting drive motor 8231 rotates reversely, it drives the transmission gear 32 to rotate reversely, so that the movable plate 2 and the receiving plate 4 are synchronously lowered. The above structure has high transmission efficiency and high transmission accuracy.

[0047] Specifically, the lifting drive motor 8231 is a servo motor, which has a brake function, which can prevent the pipe from falling and causing safety hazards due to a sudden power failure of the lifting drive motor 8231 when the pipe is cut, supported or connected.

[0048] See also Figure 7 In some embodiments, a vertically extending lifting rail 34 is disposed on the front side of the bottom plate 13, a lifting slider 35 is slidably disposed on the lifting rail 34, and the front side of the lifting slider 35 is fixedly connected to the rear side of the movable plate 2. The above arrangement can ensure that the movable plate 2 maintains linear motion, reduces friction and vibration during motion, and thus ensures the follow-up support effect of the receiving plate 4 on the pipe.

[0049] See also Figure 7 In some embodiments, two buffer blocks 36 are fixedly connected to the rear side of the movable plate 2, and the transmission gear 32 is located between the two buffer blocks 36; two first limit blocks 37 are fixedly connected to the front side of the bottom plate 13, and the two buffer blocks 36 are respectively located between the two first limit blocks 37. When the movable plate 2 shakes or moves to a large extent due to unexpected circumstances during the lifting process, the buffer blocks 36 can play a buffering and protective role to protect the transmission components. In addition, it can also play a role in limiting the movement of the movable plate 2.

[0050] See also Figure 7In some embodiments, the receiving drive member 5 is an inclined receiving cylinder, the cylinder body of the receiving cylinder is hinged to the lower part of the movable plate 2 through a first hinge seat 51, and the piston of the receiving cylinder is hinged to the free end of the lower surface of the receiving plate 4 through a second hinge seat 52. The receiving cylinder rises when the movable plate 2 rises and falls when the movable plate 2 falls. When the output end is in a fully extended state, the receiving plate 4 is in a horizontal state to support the cutting of the pipe or assist in the unloading of the pipe; when the output end is in a fully retracted state, the receiving plate 4 is tilted downward to provide guidance for the pipe to be dropped into the unloading rack.

[0051] See also Figure 5 In some embodiments, the receiving plate 4 is provided with an avoidance hole extending along its width direction, and a bearing 841 seat 41 is provided at both ends of the avoidance hole, and a heavy-duty roller 42 is rotatably provided between the two bearing 841 seats 41, and the upper part of the heavy-duty roller 42 protrudes out of the avoidance hole. The avoidance hole is provided for installing the bearing 841 seat 41 and the heavy-duty roller 42, and by limiting the height of the heavy-duty roller 42, it plays a role in supporting the cutting of the pipe and reducing the friction of the large and heavy pipe when the pipe moves in the axial direction or left and right direction.

[0052] In summary, the present invention can reduce the space occupied by the combined material receiving rack by splitting the material receiving mechanism 10 and the material receiving assembly 20, with low manufacturing cost and convenient shipment and transportation. Furthermore, by setting the lifting drive 3, the movable plate 2 and the material receiving plate 4 can be lifted and lowered with movement, and can be supported with movement; the material receiving drive 5 can be used to support the pipe when the material receiving plate 4 is horizontal, and to discharge the pipe when it is tilted downward; in addition, the material storage bayonet formed by the transport chain 73 and the material limiting block 74 can be used to store the pipe, so as to avoid displacement of the pipe when the pipe is transported, and to achieve smooth transportation and discharge of the pipe.
