Description

Technical Field

[0001] The present invention relates to the technical field of bar material collection, in particular to a bar material rounding and collecting system. Background Art

[0002] The collection of bar stock typically requires a fixed weight for tying with tape. The existing collection method typically involves transporting the bar stock along an assembly line, placing a collection hook at the end of the line to collect the bar stock, and then weighing the collected bar stock. The bar stock must also be manually shaped into a nearly circular shape before being manually removed with the tying tape. This cumbersome, time-consuming, and labor-intensive process is also labor-intensive, as the bar stock itself is prone to rolling, significantly increasing the difficulty of manual labor. Furthermore, when the bar stock falls from the assembly line onto the collection hook, the large height difference and inherent properties of the bar stock can lead to damage. Summary of the Invention

[0003] Based on this, the object of the present invention is to provide a bar rounding and material collection system.

[0004] A bar rounding and receiving system includes an assembly line, a receiving mechanism and a rounding mechanism; the receiving mechanism is arranged at the end of the assembly line, and includes a collecting hook, and the collecting hook is provided with a groove for collecting incoming materials on the assembly line; the rounding mechanism is arranged outside the collecting hook, and includes a rotating block, a plurality of thin sheets and a fixed block, a circular through hole is provided in the middle of the rotating block, the fixed block is fixed in the middle of the rotating block, the fixed block is provided with a circular through hole, the rotating block can rotate relative to the fixed block, one end of the plurality of thin sheets is fixed to the rotating block, and the other end is fixed to the fixed block, the thin sheets are arc-shaped near the middle of the fixed block, and the plurality of thin sheets are evenly spaced, and the arc part in the middle forms a circle.

[0005] The bar rounding and collecting system described in the present invention utilizes a rounding mechanism to perform rounding operations on the bar material that falls into the collecting hook, and can realize the rounding of bars of different diameters and equal weights, which is beneficial to the clamping of the clamping jig and the subsequent cable tie operation, and can save time and efficiently perform clamping and material collection, greatly saving time and liberating labor.

[0006] Furthermore, the full circle mechanism also includes a double-rod cylinder, which is arranged at the bottom of the rotating block and is used to drive the full circle mechanism as a whole to move toward or away from the collecting hook.

[0007] Furthermore, a guide plate is provided at one end of the collecting hook close to the outside of the assembly line.

[0008] Furthermore, the material collection mechanism also includes a bar support plate, an electric push rod, a first photoelectric switch, a second photoelectric switch, and several sensor plates; the bar support plate is arranged at the end of the assembly line to support the bar stock; the collection hooks are arranged on both sides of the bar support plate; the electric push rod is connected to the bar support plate to control the up and down movement of the bar push rod; the first photoelectric switch is arranged above the collection hook, and when the bar on the collection hook reaches the height of the first photoelectric switch, the first photoelectric switch sends a signal, and the electric push rod descends; the second photoelectric switch is arranged on the bar push plate, and the sensor plates are arranged in the sensing direction of the second photoelectric switch from top to bottom. When the second photoelectric switch senses the sensor plate, it sends a signal to stop the electric push rod. After the electric push rod completely stops, it resumes its descent until it completely falls into the groove of the collection hook. The electric push rod is used to cooperate with the sensor to rise and fall, and the multi-level height change protects the bar product and avoids the risk of the bar breaking due to falling too high.

[0009] Furthermore, the material receiving mechanism further includes a weighing plate and a weighing sensor; the weighing plate is disposed at the bottom of the groove of the collecting hook, and the weighing sensor is disposed at the bottom of the weighing plate for weighing the bars on the weighing plate. The weighing sensor weighs the bars on the weighing plate, thereby achieving fixed weight material receiving.

[0010] Furthermore, a blocking mechanism is provided on the assembly line, comprising a blocking block at the end of the assembly line. The required weight of the bar is set for the weighing sensor. When the bar on the weighing plate reaches the set weight, a signal is sent to the blocking mechanism on the assembly line, and the blocking block of the blocking mechanism blocks the bar on the assembly line. The blocking mechanism can effectively block the bar, preventing excess bar from falling onto the weighing plate, resulting in inaccurate weight, and preventing it from affecting subsequent clamping operations.

[0011] Furthermore, the blocking mechanism also includes baffles arranged on both sides of the conveying direction of the assembly line, which are used to limit the shape of the incoming bars and prevent the bars from falling.

[0012] Furthermore, it also includes a clamping jig, which includes a mounting plate, a fixed jaw, a movable jaw, a guide rail, a rodless cylinder and a robot; the fixed jaw is fixedly mounted on the mounting plate, the movable jaw is mounted on the mounting plate via the guide rail, the rodless cylinder is connected to the movable jaw, and drives the movable jaw to slide on the guide rail and move back and forth in the direction close to the fixed jaw; the fixed jaw and the movable jaw are respectively semicircular jaws, and when the fixed jaw and the movable jaw are closed, the closed state is circular; the robot is a six-axis robot, connected to the mounting plate, and drives the mounting plate to move. The clamping jig utilizes a double clamping form, with one side fixed and the other side moving. After the clamped product is closed, the product is nearly circular, avoiding damage to the shape of the bar material after the rounding mechanism, and is well suited for the needs of cable tie operations in cable tie machines.

[0013] Furthermore, it also includes a cable tie machine, wherein the clamping fixture clamps the rounded bar material and then moves it to the cable tie machine for cable tying.

[0026] The present invention describes that after the bar material passes through the assembly line 1, the collecting hook 21 at the end collects the bar material. Since the bar material needs to be tied with a fixed weight after collection, a weighing sensor 28 is added at the bottom of the collecting hook 21. When a certain weight is reached, the assembly line stops and the blocking mechanism blocks the bar material. Due to the large height difference of the bar material falling and the properties of the bar material itself, it may be easily broken or damaged. Therefore, an electric push rod 23 and a sensor are added to realize the multi-level height drop of the bar material. When tying the band, the bar material needs to be round and in a tightened state. Then, when the bar material completely falls into the collecting hook 21, the rounding mechanism 3 tightens the bar material into a full circle. On the clamping fixture 4, a clamping jaw is used, which is fixed and moved at the same time, so that the bar material is slowly collected upward under the drive of the moving jaw 43. Finally, the two halves of the jaws are closed, the bar material is tightened, and then the banding operation on both sides is performed.

[0027] See also Figure 1-5 The bar rounding and collection system of the present invention includes an assembly line 1, a collection mechanism 2, a rounding mechanism 3, a clamping fixture 4, and a tie-tying machine 5. The collection mechanism 2 is located at the end of the assembly line 1 in the direction of transport, the tie-tying machine 5 is located to the side of the end of the assembly line 1, and the clamping fixture 4 is located above the end of the assembly line 1. Bars flow through the assembly line 1 into the collection mechanism 2 at the end. After the collection mechanism 2 collects and rounds the bars in a certain quantity, the clamping fixture 4 grabs the rounded bars and then transports them to the tie-tying machine 5 for banding.

[0028] The assembly line 1 is a common assembly line 1 in the prior art. Preferably, a blocking mechanism is provided on the assembly line 1, comprising baffles provided on both sides of the assembly line 1 in the transport direction and a blocking block at the end of the assembly line 1. The baffles provided on both sides of the assembly line 1 in the transport direction are used to limit the shape of incoming bar stock, so that the bar stock passes through the baffles and enters the receiving mechanism 2 to prevent it from falling to the ground. The blocking block at the end of the assembly line 1 is controlled by a cylinder. When sufficient bar stock is collected in the receiving mechanism 2, the cylinder drives the blocking block to block the bar stock on the assembly line 1.

[0029] The material receiving mechanism 2 includes a collecting hook 21, a bar support plate 22, an electric push rod 23, a first photoelectric switch 24, a second photoelectric switch 25, a plurality of induction plates 26, a weighing plate 27, and a weighing sensor 28. The bar support plate 22 is arranged at the end of the assembly line 1, and the collecting hook 21 is arranged on both sides of the bar support plate 22. A guide plate 211 is provided at one end of the collecting hook 21 close to the outer side of the assembly line 1. The collecting hook 21 is provided with a groove. When the bar is transported to the end of the assembly line 1, it enters the guide plate 211 for guidance and first falls on the bar support plate 22. The bar support plate 22 supports the bar and drives the bar to fall into the groove of the collecting hook 21. The electric push rod 23 is connected to the bar support plate 22 to control the up and down movement of the bar push plate; the first photoelectric switch 24 is arranged above the collecting hook 21. When the bar on the collecting hook 21 reaches the height of the first photoelectric switch 24, the first photoelectric switch 24 sends a signal to the electric push rod 23, and the electric push rod 23 descends; the second photoelectric switch 25 is arranged on the bar support plate 22, and the plurality of sensor sheets 26 are arranged in sequence from top to bottom in the sensing direction of the second photoelectric switch 25. When the electric push rod 23 descends to a certain height, The second photoelectric switch 25 senses the sensor sheet 26 and sends a signal to the electric push rod 23 to stop moving. The electric push rod 23 starts to descend again after completely stopping. The second photoelectric switch 25 senses the sensor sheet 26 below and stops the electric push rod 23 again. The process is repeated until it completely falls into the groove of the collecting hook 21. The multi-level height descent of the bar material can be achieved through the electric push rod 23 and the photoelectric switch, which can avoid the risk of splashing or breaking of the bar material due to directly falling to the high height of the weighing plate 27, thereby having a good protective effect on the bar material. The weighing plate 27 is arranged at the bottom of the groove of the collecting hook 21, and the electric push rod 23 drives the rod to fall onto the weighing plate 27; the weighing sensor 28 is arranged below the weighing plate 27 to weigh the rod on the weighing plate 27. The required weight of the rod is set for the weighing sensor 28. When it is sensed that the rod on the weighing plate 27 reaches the set weight, a signal is sent to the blocking mechanism on the assembly line 1. The blocking block of the blocking mechanism blocks the rod on the assembly line 1 to prevent excess rod from falling into the weighing plate 27 and causing inaccurate weight.

[0030] The circular mechanism 3 is located outside the weighing plate 27 and includes a rotating block 31, several thin plates 32, and a fixed block 33. The rotating block 31 is annular, and the fixed block 33 is also annular. The fixed block 33 is located in the center of the circular shape of the rotating block 31. The thin plates 32 are fixed to the rotating block 31 at one end and to the fixed block 33 at the other end. The thin plates 32 are arc-shaped near the center of the fixed block 33, and the thin plates 32 are evenly spaced, forming a circle. When the rotating block 31 rotates, the fixed block 33 remains stationary, while the ends of the thin plates 32 fixed to the rotating block 31 move, causing the arc portions of the thin plates 32 to shift, thereby changing the size of the circle in the middle. As the circle shrinks, the ends of the bar stock are tightened in a circular manner. In this embodiment, five thin plates 32 are fixed to the rotating block and the fixed block. In another embodiment, multiple thin plates 32 are fixed to the rotating block and the fixed block.

[0031] Preferably, the circular mechanism 3 is further provided with a double-rod cylinder 34, which is provided at the bottom of the rotating block 31. The circular mechanism 3 is controlled by the double-rod cylinder 34 as a whole, and moves in a direction away from the bar or close to the bar. In the initial state, the circular mechanism 3 is moved in a direction away from the bar to prevent the bar from being blocked from falling into the collecting hook 21 for collection. After sufficient bar is collected on the weighing plate 27, the double-rod cylinder 34 moves the circular mechanism 3 in a direction close to the bar, and the two ends of the bar extend into the circle in the middle of the fixed block 33, and then the thin sheet 32 ​​is tightened to tighten the two ends of the bar in a circular manner. By using the circular mechanism 3 to tighten the bar that falls into the collecting hook 21 in a circular manner, the circular arrangement of bars of different diameters and equal weight can be achieved, which is beneficial to the clamping of the clamping jig 4 and the subsequent cable tie operation.

[0032] The clamping fixture 4 includes a mounting plate 41, a fixed jaw 42, a movable jaw 43, a guide rail 44, a rodless cylinder 45, and a robot 46. The fixed jaw 42 is fixedly mounted on the mounting plate 41, and the movable jaw 43 is mounted on the mounting plate 41 via the guide rail 44. The rodless cylinder 45 is connected to the movable jaw 43, driving the movable jaw 43 to slide on the guide rail 44 and move back and forth toward the fixed jaw 42. The fixed jaw 42 and the movable jaw 43 are respectively semicircular jaws. When the fixed jaw 42 and the movable jaw 43 are closed, the closed state is circular. The robot 46 is a six-axis robot 46, which is connected to the mounting plate 41 and drives the mounting plate 41 to move. After the rounding mechanism 3 tightens the bar in a full circle, the robot 46 drives the mounting plate 41 to move closer to the bar, and then the rodless cylinder 45 drives the moving jaw 43 and the fixed jaw 42 to close to clamp the rounded bar.

[0033] The cable tie machine 5 is a common cable tie machine 5 in the prior art. The robot 46 carries the bar material on the clamping fixture 4 and moves it to the cable tie machine 5 for cable tie. The bar material is tightened in a full circle by the rounding mechanism 3 and the clamping claws of the rounded mechanism 3 are in a round shape, which is well suited for the cable tie operation in the cable tie machine 5.

[0034] During operation, the bar material is transmitted through the assembly line 1, and the baffles on both sides of the assembly line 1 limit the shape of the bar material and prevent the bar material from falling; the bar material passes through the end of the assembly line 1 through the guide plate 211 and enters the collecting hook 21, and first falls on the bar material support plate 22. When the bar material on the collecting hook 21 reaches the height of the first photoelectric switch 24, the first photoelectric switch 24 sends a signal, and the electric push rod 23 drives the bar material support plate 22 to descend. When the second photoelectric switch 25 senses the sensor sheet 26, it sends a signal to the electric push rod 23 to stop moving. After stopping, the electric push rod 23 moves downward again, realizing the descent of the electric push rod 23 at multiple levels until the bar material falls on the weighing plate 27, avoiding the risk of splashing or breaking of the bar material due to directly falling to the high height of the weighing plate 27, which is beneficial to the bar material. Very good protection; the weighing sensor 28 is used to weigh the bar material falling onto the weighing plate 27 to realize the quantitative material collection function, which is simple and convenient. When the bar material reaches the set weight, the blocking block on the assembly line 1 blocks the bar material to prevent excess bar material from falling into the weighing plate 27, resulting in inaccurate weight, and can avoid affecting the subsequent clamping operation; the double-rod cylinder 34 drives the round mechanism 3 to approach the two ends of the bar material, and drives the thin film 32 to open and close by rotating the rotating block 31, and tightens the two ends of the bar material in a full circle; the robot 46 carries the clamping fixture 4 to grab the rounded bar material, and uses two semicircular arc clamps in the form of double clamping, fixing one side and moving the other side. After the clamped product is closed, the product is almost round, avoiding destroying the shape of the bar material after the rounding of the round mechanism 3. Finally, the robot 46 carries the clamping fixture 4 to perform cable tie operations.

[0035] The bar rounding and receiving system of the present invention utilizes a weighing sensor 28 to weigh the bar on the weighing plate 27 to achieve fixed weight receiving; a blocking mechanism is utilized to block the bar on the assembly line 1, so that the robot 46 carrying the clamping fixture 4 is not affected for clamping, and at the same time, when the weighing sensor 28 reaches a certain weight, the blocking mechanism is utilized to block it, so as to avoid weight inaccuracies; an electric push rod 23 is utilized to cooperate with the sensor for lifting and lowering, and multi-level height changes are utilized to protect the bar product and avoid the risk of the bar breaking due to the falling height being too high; a rounding mechanism 3 is utilized to perform a round tightening operation on the bar falling into the collecting hook 21, so that the rounding of bars of different diameters and equal weights can be achieved, which is beneficial to the clamping of the clamping fixture 4 and the subsequent cable tie operation; the clamping fixture 4 utilizes a double clamping form, with one side fixed and the other side moving. After the clamped product is closed, the product is nearly round, avoiding destruction of the shape of the bar after the rounding mechanism 3 is rounded, and is well suited for the needs of cable tie operations in the cable tie machine 5. The present invention can round, collect and clamp bars of different diameters, and can also save time and efficiently perform clamping and material extraction, thereby greatly saving time and liberating labor.

[0036] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the spirit of the present invention, and the present invention is intended to encompass such modifications and variations.
