Description

Technical Field

[0001] The present invention relates to the technical field of transportation production lines, and particularly to a guiding and stopping device and a hoisting and transportation production line. Background Art

[0002] In the painting production line of working machinery, a hanging transmission device, a loading robot and an unloading robot are usually provided. During the spraying production operation, workpieces such as steel pipes are hung on the transmission device by the loading robot and spraying operations are carried out. After the spraying operation is completed, the transmission device transports the workpiece to the stop position, and then the unloading robot grabs the workpiece to the next process. After the workpiece is transported to the stop position, it will continue to shake for a period of time due to inertia. In the prior art, a stopping structure such as a cylinder is usually provided to quickly stop the workpiece so that the unloading robot can quickly grab the workpiece and improve production efficiency. However, this kind of stopping structure has a high cost and is prone to failure. Summary of the Invention

[0003] The present invention provides a guiding and stopping device and a hoisting and transportation production line to solve or improve the problems of high cost and high failure rate of the existing stopping structure.

[0004] According to a first aspect of the present invention, a guiding and stopping device is provided, comprising:

[0005] A support and guiding assembly;

The guiding groove is arranged along the transportation direction of the workpiece. The stopping mechanism is arranged inside the guiding groove.

[0008] According to a guiding and stopping device provided by the present invention, the guiding frame includes a main guiding body.

[0009] Among them, the main guiding body includes a first side plate and a second side plate. The first side plate and the second side plate are respectively connected to both sides of the support baffle. The first side plate and the second side plate are parallel to each other. A guiding groove is formed between the first side plate and the second side plate. Both ends of the connection end of the heavy side and the light side are rotatably connected to the first side plate and the second side plate respectively.

[0010] According to a guiding and stopping device provided by the present invention, the guiding frame further includes a secondary guiding body.

[0011] Among them, the secondary guiding body includes a first secondary side plate and a second secondary side plate. One end of the first secondary side plate is connected to one end of the first side plate close to the workpiece transportation inlet, and the other end of the first secondary side plate extends in a direction away from the outer wall of the first side plate. One end of the second secondary side plate is connected to one end of the second side plate close to the workpiece transportation inlet, and the other end of the second secondary side plate extends in a direction away from the outer wall of the second side plate. A secondary guiding groove is formed between the first secondary side plate and the second secondary side plate. The secondary guiding groove communicates with the guiding groove.

[0012] According to a guiding and stopping device provided by the present invention, the secondary guiding body further includes a first auxiliary guiding wheel set and a second auxiliary guiding wheel set. The first auxiliary guiding wheel set is arranged on one side of the first secondary side plate close to the secondary guiding groove. The second auxiliary guiding wheel set is arranged on one side of the second secondary side plate close to the secondary guiding groove.

[0013] According to a guiding and stopping device provided by the present invention, the support guiding assembly further includes a main telescopic support frame and a secondary telescopic support frame.

[0014] The main telescopic support frame is supported and connected to the lower side of the main guiding body to support and adjust the height of the main guiding body; the secondary telescopic support frame is connected to the lower side of the secondary guiding body to support and adjust the height of the secondary guiding body.

[0015] According to a guiding and stopping device provided by the present invention, the support guiding assembly further includes a driving mechanism. The driving mechanism is connected to the main telescopic support frame and the secondary telescopic support frame to synchronously adjust the heights of the main telescopic support frame and the secondary telescopic support frame.

[0016] According to a guiding and stopping device provided by the present invention, a plurality of the heavy blocks are arranged at intervals along the transportation direction of the workpiece in the guiding groove.

[0017] According to a guiding and stopping device provided by the present invention, a buffer protection layer is arranged on the upper side surface of the heavy block.

[0018] According to a second aspect of the present invention, there is provided a lifting and transporting production line, comprising a transmission device, a rotating device, a primary lifting device, a secondary lifting device and the guide stop device as described above.

[0019] The transmission device is arranged along the transmission direction of the workpiece. The slewing device is rotatably connected to the transmission device. The primary hoist is connected to the slewing device. The secondary hoist is connected to the primary hoist. The secondary hoist is used to be movably connected to the workpiece. The guide stop device is arranged at the end position of the hoisting and transporting production line.

[0020] In the guide stop device provided by the present invention, a support guide assembly and a stop mechanism are included. The support guide assembly can provide a supporting connection function for the stop mechanism. The stop mechanism includes a biased weight block and a support baffle. The biased weight block includes a biased weight side and a biased light side. The weight of the biased weight side is greater than the weight of the biased light side. The biased weight side is set at a side close to the workpiece transportation entrance, and the biased light side is set at a side away from the workpiece transportation entrance. The biased weight side is connected to the biased light side, and the connecting ends of the two are rotatably connected to the support guide assembly. For example, a rotating shaft is provided at the connecting end of the biased weight side and the biased light side, and the rotating shaft is rotatably connected to the support guide assembly. In the absence of external force, the biased weight side can always press down and lift the biased light side. A support baffle connected to the support guide assembly is provided below the biased weight side. The support baffle is used to limit the support of the biased weight side. That is, the support baffle is used to limit the downward pressure limit of the biased weight side. In the absence of external force, the downward pressure of the biased weight side is greater than the downward pressure of the biased light side. The heavy stopper will rotate with the connection end between the heavy side and the light side as the rotation axis, pressing the heavy side downward and tilting the light side upward until the end of the heavy side away from the light side presses against the support baffle. In actual use, the lower end of the workpiece should be located between the upper and lower ends of the light side when there is no external force, so that when the workpiece moves from the transport entrance to the transport exit, the lower end of the workpiece can press and push the light side to flip downward and pass over the heavy stopper. When the workpiece passes over the heavy stopper, the light side can rotate and stop the workpiece.

[0021] During the transportation of the workpiece, when the workpiece has not moved to the stop mechanism, the heavy side is pressed downward, the light side is tilted upward, and the end of the heavy side is pressed against the support baffle. When the workpiece moves to the stop mechanism, first, the lower end of the workpiece presses against the light side to cause the heavy block to rotate, and the light side flips downward, and the heavy side flips upward, until the workpiece passes over the light side. Subsequently, under the action of gravity on the heavy side, the heavy side flips downward, and the light side flips upward, and the heavy block rotates back to the position where the heavy side presses against the support baffle. At this time, when the workpiece suddenly stops and shakes, the light side stops the workpiece, so that the workpiece quickly stops shaking and remains stationary at the stop position, thereby enabling the unloading robot to quickly grab the workpiece to the next process, thereby improving production efficiency.

[0022] With this structural arrangement, a weight block including a heavier side and a lighter side is rotatably arranged on the support and guiding assembly, so that the weight block cooperates with the support baffle to achieve a rapid stopping effect during the transportation of the suspended workpiece. Its structure is simple, the failure rate is relatively low, and the cost is also relatively low.

[0023] Furthermore, since the hoisting and transportation production line includes the guiding and stopping device as described above, it also has all the advantages described above. Description of the Drawings

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0039] The following will be combined with Figures 1 to 7 to describe a guiding and stopping device and a hoisting and transportation production line provided by an embodiment of the present invention. It should be understood that the following is only a schematic embodiment of the present invention and does not constitute any special limitation to the present invention.

[0040] An embodiment of the first aspect of the present invention provides a guiding and stopping device, as Figures 1 to 6 shown. The guiding and stopping device includes:

[0041] A support guiding assembly 100;

[0042] A stopping mechanism 200, the stopping mechanism 200 includes a heavy-biased block 210 and a support baffle 220. The heavy-biased block 210 includes a heavy-biased side 211 and a light-biased side 212. The heavy-biased side 211 is connected to the light-biased side 212, and the connection end between the two is rotatably connected to the support guiding assembly 100. The heavy-biased side 211 is arranged on the side close to the workpiece 700 input port, and the light-biased side 212 is arranged on the side far from the workpiece 700 input port. The support baffle 220 is connected to the support guiding assembly 100 and is located below the heavy-biased side 211 to limit and support the heavy-biased side 211.

[0043] In the guide stop device provided by the present invention, a support guide assembly 100 and a stop mechanism 200 are included. The support guide assembly 100 can provide a supporting connection function for the stop mechanism 200. The stop mechanism 200 includes a biased weight block 210 and a support baffle 220. The biased weight block 210 includes a biased weight side 211 and a biased light side 212. The weight of the biased weight side 211 is greater than the weight of the biased light side 212. The biased weight side 211 is set at a side close to the transport entrance of the workpiece 700, and the biased light side 212 is set at a side away from the transport entrance of the workpiece 700. The biased weight side 211 is connected to the biased light side 212, and the connecting ends of the two are rotatably connected to the support guide assembly 100. For example, a rotating shaft is provided at the connecting end of the biased weight side 211 and the biased light side 212, and the rotating shaft is rotatably connected to the support guide assembly 100. In the absence of external force, the biased weight side 211 can always press down and lift the biased light side 212. A support baffle 220 connected to the support guide assembly 100 is provided below the heavy side 211. The support baffle 220 is used to limit the support of the heavy side 211. That is, the support baffle 220 is used to limit the downward pressure limit of the heavy side 211. In the absence of external force, the downward pressure of the heavy side 211 is greater than the downward pressure of the light side 212. The heavy block 210 will rotate with the connection end between the heavy side 211 and the light side 212 as the axis of rotation, the heavy side 211 is pressed downward, and the light side 212 is tilted upward, until the end of the heavy side 211 away from the light side 212 is pressed against the support baffle 220. In actual use, the lower end of the workpiece 700 should be located between the upper and lower ends of the light side 212 when no external force is applied, so that when the workpiece 700 moves from the transport entrance to the transport exit, the lower end of the workpiece 700 can press and push the light side 212 to flip downward and pass over the heavy stopper 210. When the workpiece 700 passes over the heavy stopper 210, the light side 212 can rotate and stop the workpiece 700.

[0044] During the transportation of the workpiece 700, when the workpiece 700 has not moved to the stop mechanism 200, the heavy side 211 is pressed downward, the light side 212 is tilted upward, and the end of the heavy side 211 is pressed against the support baffle 220. When the workpiece 700 moves to the stop mechanism 200, first, the lower end of the workpiece 700 presses against the light side 212 to rotate the heavy stop block 210, the light side 212 is turned downward, and the heavy side 211 is turned upward, until the workpiece 700 passes over the light side 212. Subsequently, under the action of gravity of the heavy side 211, the heavy side 211 is turned downward, and the light side 212 is turned upward, and the heavy stop block 210 is rotated back to the position where the heavy side 211 is pressed against the support baffle 220. At this time, when the workpiece 700 suddenly stops and shakes, the lighter side 212 stops the workpiece 700, so that the workpiece 700 quickly stops shaking and remains still at the stop position, thereby enabling the unloading robot to quickly grab the workpiece 700 to the next process, thereby improving production efficiency.

[0045] With this structural arrangement, a weight block 210 including a heavier side 211 and a lighter side 212 is rotatably arranged on the support and guide assembly 100, so that the weight block 210 cooperates with the support baffle 220 to achieve a rapid stopping effect during the transportation of the suspended workpiece 700. Its structure is simple, the failure rate is relatively low, and the cost is also relatively low.

[0046] In addition, the structure of the guide and stop device is simple and compact, without the need for maintenance, and its maintenance cost is also low. Through experimental verification, the stopping time of the guide and stop device does not exceed 2 seconds, and its stopping reliability is high.

[0047] For example, in an embodiment of the present invention, the weight block 210 is a square block, and the lengths, widths, and heights of the heavier side 211 and the lighter side 212 are all equal, and the density of the heavier side 211 is greater than that of the lighter side 212. Alternatively, the density of the heavier side 211 is equal to that of the lighter side 212, and the widths and heights of the heavier side 211 and the lighter side 212 correspond to be equal. The length of the heavier side 211 is greater than the length of the lighter side 212.

[0048] In an embodiment of the present invention, the support and guide assembly 100 includes a guide frame. A guide groove 113 is provided on the guide frame. The guide groove 113 is arranged along the transportation direction of the workpiece 700. The stop mechanism 200 is arranged inside the guide groove 113.

[0049] For example, a guide groove 113 is arranged on the guide frame along the transportation direction of the workpiece 700. The stop mechanism 200 is arranged in the guide groove 113. The guide and stop device can be arranged at a position close to the end of the transmission device 300. When the workpiece 700 moves to a position close to the end of the transmission device 300, it can enter the guide groove 113 and move along the guide groove 113. During the movement of the workpiece 700 in the guide groove 113, it can push the lighter side 212 of the weight block 210 to turn downward and cross over the weight block 210. When the transmission device 300 stops transporting operations, the already rotated lighter side 212 can stop the workpiece 700 from shaking. During this process, when the workpiece 700 moves in the guide groove 113, the guide groove 113 can form a constraint on the workpiece 700, reducing the shaking direction of the workpiece 700. Furthermore, it can assist the weight block 210 to quickly stop the workpiece 700.

[0050] In an embodiment of the present invention, a plurality of weight blocks 210 are arranged at intervals along the transportation direction of the workpiece 700 in the guide groove 113.

[0051] In an embodiment of the present invention, the guide frame includes a main guide body 110.

[0052] Among them, the main guiding body 110 includes a first side plate 111 and a second side plate 112. The first side plate 111 and the second side plate 112 are respectively connected to both sides of the support baffle 220. The first side plate 111 and the second side plate 112 are parallel to each other. A guiding groove 113 is formed between the first side plate 111 and the second side plate 112. Both ends of the connection end of the heavier side 211 and the lighter side 212 are respectively rotatably connected to the first side plate 111 and the second side plate 112.

[0053] Furthermore, in an embodiment of the present invention, the guiding frame further includes a secondary guiding body 120.

[0054] Among them, the secondary guiding body 120 includes a first secondary side plate 121 and a second secondary side plate 122. One end of the first secondary side plate 121 is connected to one end of the first side plate 111 close to the workpiece 700 input port, and the other end of the first secondary side plate 121 extends in a direction away from the outer wall of the first side plate 111; one end of the second secondary side plate 122 is connected to one end of the second side plate 112 close to the workpiece 700 input port, and the other end of the second secondary side plate 122 extends in a direction away from the outer wall of the second side plate 112. A secondary guiding groove 123 is formed between the first secondary side plate 121 and the second secondary side plate 122. The secondary guiding groove 123 communicates with the guiding groove 113.

[0055] For example, as Figures 1 to 6 shown, in this embodiment, 4 heavyweight stoppers 210 are arranged at intervals in the guiding groove 113. The number of heavyweight stoppers 210 can be flexibly adjusted according to the number of workpieces 700 stopped for transportation each time. The first side plate 111 and the second plate are arranged at intervals and in parallel. The support baffle 220 is connected between the first side plate 111 and the second side plate 112. Among them, the support baffle 220 can be an integral plate-like structure covering the entire guiding groove 113, or a split plate-like structure respectively provided for the heavyweight sections corresponding to each heavyweight stopper 210. Or, a connecting plate is arranged between the first side plate 111 and the second side plate 112. The support baffle 220 is connected to the upper side of the connecting plate.

[0056] A guiding groove 113 is formed between the first side plate 111 and the second side plate 112. The guiding groove 113 is a long-strip guiding groove 113. A first auxiliary side plate 121 is connected to the inlet end of the first side plate 111, and a second auxiliary side plate 122 is connected to the inlet end of the second side plate 112. Wherein, the outer ends of the first auxiliary side plate 121 and the second auxiliary side plate 122 extend along the direction away from each other. That is to say, the first auxiliary side plate 121 and the second auxiliary side plate 122 form a structure similar to an inverted V shape. A guiding sub-groove 123 is formed between the first auxiliary side plate 121 and the second auxiliary side plate 122. The guiding sub-groove 123 communicates with the guiding groove 113. When the workpiece 700 moves to a position close to the end of the conveying device 300, it first enters the guiding sub-groove 123 with a larger guiding range, and then moves from the guiding sub-groove 123 into the guiding groove 113 with a smaller guiding range.

[0057] In an embodiment of the present invention, a rotating shaft is provided at the connection end of the heavy side 211 and the light side 212 of the heavy bias block 210. Both ends of the rotating shaft are rotatably connected to the first side plate 111 and the second side plate 112 respectively. Bushings can be provided between the rotating shaft and the first side plate 111 and the second side plate 112. Alternatively, waist-shaped holes are provided on both the first side plate 111 and the second side plate 112. The waist-shaped holes are arranged along the conveying direction of the workpiece 700, and both ends of the rotating shaft pass through the waist-shaped holes on the first side plate 111 and the second side plate 112 respectively, and are locked and connected through a locking member. Wherein, the locking member includes but is not limited to a nut. Thus, the positions of the respective heavy bias baffles can be flexibly adjusted according to actual needs.

[0058] In an embodiment of the present invention, the guiding sub-body 120 further includes a first auxiliary guiding wheel group 131 and a second auxiliary guiding wheel group 132. The first auxiliary guiding wheel group 131 is arranged on the side of the first auxiliary side plate 121 close to the guiding sub-groove 123, and the second auxiliary guiding wheel group 132 is arranged on the side of the second auxiliary side plate 122 close to the guiding sub-groove 123.

[0059] For example, as Figure 1 、 Figure 3 and Figure 4 shown, the structures of the first auxiliary guiding wheel group 131 and the second auxiliary guiding wheel group 132 are the same, and both include a fixed bracket and a plurality of guiding wheel bodies. The fixed bracket is fixed to the inner side of the first auxiliary side plate 121 or the second auxiliary side plate 122, that is, the fixed bracket is fixed to the side of the first auxiliary side plate 121 or the second auxiliary side plate 122 close to the guiding sub-groove 123. The plurality of guiding wheel bodies are spaced apart and rotatably connected to the fixed bracket. The rotating shaft of the guiding wheel body is perpendicular to the conveying direction of the workpiece 700. Thus, during the transportation of the workpiece 700, when the workpiece 700 shakes and impacts on the guiding wheel body, the guiding wheel body can provide an auxiliary guiding force for the workpiece 700, assist the workpiece 700 to return to its position as soon as possible, and smoothly enter the guiding groove 113.

[0060] In one embodiment of the present invention, the support and guiding assembly 100 further includes a main telescopic support frame 140 and an auxiliary telescopic support frame 150.

[0061] The main telescopic support frame 140 is supported and connected to the lower side of the main guiding body 110 to support and adjust the height of the main guiding body 110; the auxiliary telescopic support frame 150 is connected to the lower side of the auxiliary guiding body 120 to support and adjust the height of the auxiliary guiding body 120.

[0062] Further, in one embodiment of the present invention, the support and guiding assembly 100 further includes a driving mechanism. The driving mechanism is connected to the main telescopic support frame 140 and the auxiliary telescopic support frame 150 to synchronously adjust the heights of the main telescopic support frame 140 and the auxiliary telescopic support frame 150.

[0063] As Figure 1 and Figure 6 shown, a plurality of main telescopic support frames 140 are arranged at intervals on the lower side of the main guiding body 110. The main telescopic support frame 140 includes a first main column, a second main column and a main support cross beam. Among them, the first main column is located outside the first side plate 111, and the second main column is located outside the second side plate 112, and both are arranged along the vertical direction. Both the first main column and the second main column are telescopic structures. The two ends of the main support cross beam are respectively connected to the upper ends of the first main column and the second main column. A waist-shaped hole is arranged on the main support cross beam along the direction perpendicular to the guiding groove 113. Both the first side plate 111 and the second side plate 112 are connected to the main support cross beam through fasteners passing through the waist-shaped hole. Thereby, the distance between the first side plate 111 and the second side plate 112 can be adjusted, and further the width of the guiding groove 113 can be adjusted.

[0064] An auxiliary telescopic support frame 150 is arranged on the lower side of the auxiliary guiding body 120. The auxiliary telescopic support frame 150 includes a first auxiliary column, a second auxiliary column and an auxiliary support cross beam. The first auxiliary column is located outside the first auxiliary side plate 121, and the second auxiliary column is located outside the second auxiliary side plate 122, and both are arranged along the vertical direction. Both the first auxiliary column and the second auxiliary column are telescopic structures.

The primary lifting tool 500 is connected to the slewing device 400. The secondary lifting tool 600 is connected to the primary lifting tool 500. The workpiece 700 is hung on the secondary lifting tool 600.

[0070] During the working process, the loading robot first hoists the workpiece 700 onto the secondary lifting tool 600, and the conveyor chain drives the primary lifting tool 500 to drive the secondary lifting tool 600 and the workpiece 700 to move along its transmission direction and perform spraying operations. During the spraying process, the slewing device 400 can also drive the primary lifting tool 500 to drive the secondary lifting tool 600 and the workpiece 700 to rotate to achieve omnidirectional rotary spraying. After spraying is completed, the transmission device 300 transports the workpiece 700 to the stop position at the end of the hoisting and transportation production line and stops the transmission. The guiding and stopping device can quickly stop the swaying workpiece 700, so that the unloading robot can quickly and accurately grab the workpiece 700 to the next process. Through experimental verification, the time for the guiding and stopping device to stop the workpiece 700 does not exceed 2 seconds, greatly improving the production efficiency.

[0071] Furthermore, since the hoisting and transportation production line includes the guiding and stopping device as described above, it also has the above-mentioned various advantages.
