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

[0002] The collection of bar materials usually requires a fixed weight for binding.

The overall process is cumbersome, time-consuming and labor-intensive, and the bar materials themselves have the characteristic of being easy to roll, which greatly increases the difficulty of manual work. In addition, when the bar materials fall from the assembly line into the collection hook, due to the large height difference of the fall and the properties of the bar materials themselves, the bar materials may be damaged.

[0026] The present invention describes that after the rods are fed through the assembly line 1, the collecting hook 21 at the end collects the rods. Since the rods need to be tied with a fixed weight after being collected, 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 rods. Due to the large height difference of the rods falling and the properties of the rods themselves, they may be easily broken or damaged. Therefore, an electric push rod 23 and a sensor are added to achieve multi-level height descent of the rods. When tying the tape, the rods need to be round and in a tightened state. Then, when the rods completely fall into the collecting hook 21, the rounding mechanism 3 tightens the rods into a round circle. On the clamping fixture 4, a clamping jaw is used, which is fixed while moving, so that the rods are slowly collected upwards under the drive of the moving jaws 43. Finally, the two halves of the jaws are closed to tighten the rods, and then the tying of the tapes on both sides is performed.

[0027] See also Figure 1-5 The bar rounding and receiving system of the present invention comprises an assembly line 1, a receiving mechanism 2, a rounding mechanism 3, a clamping fixture 4 and a tie-tying machine 5. The receiving mechanism 2 is arranged at the end of the assembly line 1 in the transport direction, the tie-tying machine 5 is arranged at the side of the end of the assembly line 1, and the clamping fixture 4 is arranged above the end of the assembly line 1. The bar flows through the assembly line 1 to the receiving mechanism 2 at the end, and the bar is quantitatively collected and rounded by the receiving mechanism 2. The clamping fixture 4 grabs the rounded bar and then transports it to the tie-tying machine 5 for tying.

[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, and the blocking mechanism includes baffles provided on both sides of the conveying direction of the assembly line 1 and a blocking block at the end of the assembly line 1, wherein the baffles on both sides of the conveying direction of the assembly line 1 are used to limit the incoming shape of the bar material, and the bar material enters the receiving mechanism 2 after being limited by the baffles to prevent it from falling to the ground; the blocking block at the end of the assembly line 1 is controlled by a cylinder, and when enough bar materials are collected in the receiving mechanism 2, the cylinder drives the blocking block to block the bar materials 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 sheets 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 arranged 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 bar push plate to move up and down; the first photoelectric switch 24 is arranged above the collecting hook 21, and 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 induction sheets 26 are arranged in sequence from top to bottom in the induction 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 rods can be achieved through the electric push rod 23 and the photoelectric switch, which can avoid the risk of splashing or breaking of the rods due to directly falling to the high height of the weighing plate 27, thereby providing good protection for the rods. 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 material to fall onto the weighing plate 27; the weighing sensor 28 is arranged below the weighing plate 27 to weigh the rod material on the weighing plate 27, and the required weight of the rod material is set for the weighing sensor 28. When it is sensed that the rod material on the weighing plate 27 reaches the set weight, a signal is sent to the blocking mechanism on the assembly line 1, and the blocking block of the blocking mechanism blocks the rod material on the assembly line 1 to prevent excess rod material from falling into the weighing plate 27 and causing inaccurate weight.

[0030] The full circle mechanism 3 is arranged outside the weighing plate 27, and includes a rotating block 31, a plurality of thin sheets 32 and a fixed block 33. The rotating block 31 is an annular structure, and the fixed block 33 is an annular structure. The fixed block 33 is arranged in the middle of the annular rotating block 31; one end of the plurality of thin sheets 32 is fixed on the rotating block 31, and the other end is fixed on the fixed block 33. The thin sheets 32 are arc-shaped near the middle part of the fixed block 33, and the plurality of thin sheets 32 are evenly spaced, and the arc part in the middle forms a circle. When the rotating block 31 rotates, the fixed block 33 is fixed, and one end of the thin sheet 32 ​​fixed on the rotating block 31 moves, so that the arc part of the thin sheet 32 ​​is offset, thereby changing the size of the middle circle, so that the two ends of the bar are tightened in a full circle when the circle is reduced. In this embodiment, five thin sheets 32 are fixed on the rotating block and the fixed block. In another embodiment, multiple thin sheets 32 are fixed on the rotating block and the fixed block.

[0031] Preferably, the rounding mechanism 3 is also provided with a double-rod cylinder 34, which is arranged at the bottom of the rotating block 31. The rounding 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 rounding mechanism 3 is moved in a direction away from the bar to prevent the bar from falling into the collecting hook 21 for collection. After collecting enough bar on the weighing plate 27, the double-rod cylinder 34 moves the rounding 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 full circle. The rounding mechanism 3 is used to tighten the bar falling into the collecting hook 21 in a full circle, so that bars of different diameters and equal weight can be rounded, which is conducive to the clamping of the clamping fixture 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, the movable jaw 43 is mounted on the mounting plate 41 through the guide rail 44, the rodless cylinder 45 is connected to the movable jaw 43, drives the movable jaw 43 to slide on the guide rail 44, and reciprocates toward the fixed jaw 42; the fixed jaw 42 and the movable jaw 43 are semicircular jaws respectively, and 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, connected to the mounting plate 41, and drives the mounting plate 41 to move. After the rounding mechanism 3 tightens the bar in a round shape, 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 clamped by the clamping claws that are tightened in a full circle by the full circle mechanism 3 and closed in a round shape is well suited to the needs of 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 multi-level height descent of the electric push rod 23 until the bar material falls on the weighing plate 27, thereby 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 rounding mechanism 3 to approach the two ends of the bar material, and drives the thin sheet 32 ​​to open and close by rotating the rotating block 31, so as to tighten the two ends of the bar material in a rounded manner; 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, with one side fixed and the other side moving. After the clamped product is closed, the product is almost round, avoiding damage to the shape of the bar material after the rounding mechanism 3 is rounded. 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 uses a weighing sensor 28 to weigh the bars on the weighing plate 27 to achieve fixed weight receiving; a blocking mechanism is used to block the bars on the assembly line 1, so that the robot 46 carrying the clamping fixture 4 for clamping is not affected. At the same time, when the weighing sensor 28 reaches a certain weight, the blocking mechanism is blocked, which can avoid inaccurate weight; the electric push rod 23 is used to cooperate with the sensor to lift and lower, and the multi-level height changes are used to protect the bar product to avoid the risk of the bar breaking due to the falling height being too high; the rounding mechanism 3 is used to tighten the bars falling into the collecting hook 21, so that the rounding of bars of different diameters and equal weights can be achieved, which is conducive to the clamping of the clamping fixture 4 and the subsequent cable tie operation; the clamping fixture 4 uses a double clamping form, one side is fixed and the other side is moved. After the clamped product is closed, the product is nearly circular, avoiding the destruction of the shape of the bar after the rounding mechanism 3 is rounded, and it is well suitable for the needs of cable tie operation 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-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and the present invention is also intended to include these modifications and modifications.
