Description

TECHNICAL FIELD

[0001] The present application relates to the field of die casting production conveying line, in particular, to a conveying line and method for die casting machine unloading. BACKGROUND

[0002] In the field of die casting production processing, after the die casting machine completes the die casting of the casting, the processed pieces and the edge materials, such as sprue and runner waste, after unloading need to be conveyed to the subsequent processing link through the conveying line. However, the die casting machine unloading conveying line in the prior art has the following problems. On the one hand, the traditional conveying line is a single transmission channel, which cannot effectively separate the processed pieces and the edge materials, and the two are often mixed and conveyed. Additional manpower is needed for subsequent sorting, which not only increases the operation process and the labor intensity of the operator, but also easily causes the conveying channel to be congested due to material accumulation, seriously affecting the overall unloading efficiency and failing to meet the high output of the die casting machine in the prior art. On the other hand, a large amount of metal waste is often attached to the surface of the edge material unloaded from the die casting machine, and the edge material is high in temperature immediately after unloading, so the waste is easily adhered to the surface of the edge material. The existing conveying line lacks a targeted cleaning structure and can only rely on subsequent manual cleaning, which is low in cleaning efficiency and poor in effect. At the same time, the waste is easily scattered to the periphery of the equipment or the workshop floor during the conveying process, which not only increases the cleaning workload of the workshop, but also may affect the normal operation of the equipment due to waste accumulation and damage the production environment of the workshop. On the other hand, although some conveying lines are provided with lifting mechanisms to convey the processed pieces to high-position processes, the conveying belt is easily deviated or jammed during the lifting process, causing the processed pieces to slide or be stuck in the equipment. Frequent downtime is needed to handle the fault, which reduces the work efficiency and increases the labor intensity.

[0003] Therefore, the technical personnel in the field are committed to providing a conveying line and method for die casting machine unloading which can effectively solve the above technical problems. SUMMARY

[0005] Further, the material separation and transmission mechanism comprises a transmission unit, and the transmission unit is used for transmitting the processed pieces or the edge materials to the input end of the processed piece conveying mechanism or the edge material cleaning mechanism. A push-separation unit is provided on the outside of the transmission unit. The push-separation unit is located in the middle section of the transmission unit and is used to push the edge material into the edge material cleaning mechanism. A material identification unit is installed above the conveyor belt of the material distribution and conveying mechanism. The material identification unit includes an industrial camera and an AI recognition module. The industrial camera is used to collect image information of the material on the conveyor belt and transmit it to the AI ​​recognition module. The AI ​​recognition module identifies the material type through a pre-trained material classification model and sends the identification result to the control system of the push separation unit.

[0007] Furthermore, the push separation unit includes a lifting cylinder that is detachably connected to the transmission base via a lifting cylinder positioning seat. The piston rod of the lifting cylinder is fixed to the connecting piece and drives the connecting piece to move up and down. The connecting piece is slidably connected to the outer wall of the upright plate. A separation cylinder is provided on the connecting piece, and the output end of the separation cylinder is connected to the separation piece.

The upper end of the upright plate is provided with a push port that works in conjunction with the push plate. The inner end of the rear baffle extends toward the edge cleaning mechanism. The rear end of the push plate is connected to the inner end of the front baffle. The front baffle and the rear baffle are parallel to each other.

[0008] Furthermore, the connecting member includes a displacement seat, the inner side of which is slidably mounted on two slide rails, each of which is mounted on the vertical plate. A horizontal plate is provided on the outer side of the displacement seat, and the output end of the lifting cylinder is connected to the lower end of the horizontal plate. There are two separation cylinders, and the output ends of the two separation cylinders are simultaneously connected to the push plate.

[0009] Furthermore, a track is provided along the length of the front baffle, and the front baffle is slidably connected to one side of the displacement seat via a slide block and the track.

[0010] Furthermore, the edge material cleaning mechanism includes a conveyor frame, on which a conveyor belt is provided and the conveyor belt has several through holes; the conveyor belt is wound around the conveyor roller, the conveyor roller is provided on the conveyor frame, the outer side of the conveyor frame has a chain disc connected to the conveyor roller, the chain disc is connected to the drive motor in the drive box through a chain, and an outer cover is provided on the conveyor frame above the conveyor belt, and several fans are provided along the length of the outer cover; Below the conveyor belt is a first guide plate connected to the conveyor frame. The first guide plate is inclined and its lower end is located at an opening on the conveyor frame. The opening has a collection box connected to the outer wall of the conveyor frame and facing upward. The collection box is used to collect waste debris blown down by the blower. Extension plates are provided on both sides of the first guide plate, and second guide plates are provided on both sides of the extension plates. A high-pressure airflow nozzle assembly is provided inside the outer cover. The high-pressure airflow nozzle assembly is connected to a high-pressure air pump. The surfaces of the first and second guide plates are coated with polytetrafluoroethylene. The processing part conveying mechanism has the same structure as the edge material cleaning mechanism.

[0011] Furthermore, the unloading and lifting mechanism includes an unloading frame, on which an unloading conveyor belt is provided. A baffle is provided around the outer surface of the conveyor belt. Two anti-jamming protrusions are provided on the inner side of the unloading frame. The unloading conveyor belt is located between the two anti-jamming protrusions. Weight reduction holes are provided on the baffle. Notches are provided on both sides of the baffle, and each baffle is located at each of the notches.

[0012] Furthermore, a rear baffle is provided at the lower rear end of the unloading rack. Two adjustment holes are provided on the rear baffle, and a positioning screw is inserted into each adjustment hole. The outer half of the positioning screw is positioned on the rear baffle by a locking nut. The front half of the positioning screw is connected to the extension seat. The extension seat has a weight reduction port. Several limiting strips are hinged to the lower end of the extension seat. Each limiting strip extends along the length direction of the extension seat and is spaced apart. The rear end of each limiting strip has a T-shaped limiting block connected to the extension seat. Each T-shaped limiting block is used to limit the backward swing of the limiting strip.

[0013] Conveying methods for unloading materials from die-casting machines include: The transmission motor of the material distribution and transmission mechanism is started. The transmission motor drives the transmission roller on the transmission base to rotate through the chain, which in turn drives the transmission belt to run. The unloaded processed parts or edge materials are transported onto the transmission belt and move towards the tail end with the transmission belt. When the material moves to the push-separation unit in the middle of the transmission unit, if it is a workpiece, the lifting cylinder is activated, and its piston rod pushes the connecting piece to slide upward along the slide rail on the outer wall of the vertical plate until the lower end of the separating piece is higher than the workpiece. At this time, the workpiece is not obstructed and is transported to the next process through the workpiece conveying mechanism. If it is edge material, the horizontal plate of the connector drives the two separating cylinders to move synchronously. The output end of the separating cylinder pushes the push plate to move towards the edge material cleaning mechanism. The front baffle slides along the track on the displacement seat through the slide block, blocking the subsequent material. The push plate passes through the push port at the top of the vertical plate and pushes the edge material on the conveyor belt to the input end of the edge material cleaning mechanism. After the edge material enters the edge material cleaning mechanism, it falls onto the conveyor belt on the conveyor frame. The drive motor in the drive box drives the chain to rotate through the chain. The chain is connected to the conveyor roller, driving the conveyor belt to move. The fan is started and blows air downwards to blow off the waste on the surface of the edge material, which also has a cooling effect. Since there are several through holes on the conveyor belt, the waste falls through the through holes into the first guide plate or the second guide plate below and then falls into the collection box through the opening to complete the collection. The cleaned edge material is output with the conveyor belt. After the workpiece enters the unloading and lifting mechanism, it falls onto the unloading conveyor belt on the unloading rack. The unloading conveyor belt starts and transports the workpiece upwards. Two anti-jamming protrusions on the inner side of the unloading rack are located on both sides of the unloading conveyor belt to prevent the unloading conveyor belt from deviating or jamming during operation. The T-shaped limit block at the rear end of the limit bar restricts the limit bar from swinging backward to prevent edge material from falling after passing through the limit bar. At the same time, the limit bar will not obstruct the stop bar. After the workpiece is lifted to the top of the unloading rack by the unloading conveyor belt, it leaves the conveyor line and enters the next process, completing the entire die-casting machine unloading and conveying process.

[0014] The present invention has the following beneficial effects: 1. The material distribution and conveying mechanism in this invention works in conjunction with the conveying unit and the pushing and separating unit to accurately push the separating component to the edge material cleaning mechanism when the edge material is being processed, effectively avoiding material mixing. 2. The cooperative design of the front baffle and the rear baffle in the pushing and separating unit can block the subsequent material during the pushing of the edge material, prevent the conveying congestion, and ensure the continuous transmission process. This effectively improves the overall unloading conveying efficiency of the invention and meets the high output requirements of the die casting machine. 3. In the edge material cleaning mechanism, multiple fans installed along the length of the outer cover can blow air from all directions onto the edge material on the conveyor belt. This not only quickly blows off the waste on the surface of the edge material, but also cools down the hot edge material that has just been unloaded from the die-casting machine, preventing the hot waste from sticking together and affecting subsequent processing. At the same time, several through holes in the conveyor belt, together with the first guide plate, extension plate and second guide plate installed at the bottom, prevent waste from accumulating and facilitate collection. This prevents waste from scattering around the equipment or on the workshop floor, reducing cleaning workload and improving the workshop environment. 4. The unloading lifting mechanism of this invention has two anti-jamming protrusions on the inner side of the unloading frame, and the unloading conveyor belt is located between the protrusions, which can effectively limit the left and right deviation of the conveyor belt during operation and avoid material jamming; the design of the baffle can prevent the processed parts from slipping during the upward lifting process, and the weight-reducing holes opened on the baffle can reduce the load on the conveyor belt while ensuring the structural strength, further improving the conveying stability and reducing the loss of the processed parts during the lifting process; at the same time, it also has the beneficial effects of simple operation, improved work efficiency, reduced labor intensity of operators and less damage.

[0043] Conveying methods for unloading materials from die-casting machines include: Start the transmission motor 15 of the material distribution and transmission mechanism 1. The transmission motor 15 drives the transmission roller on the transmission base 11 to rotate through the chain, thereby driving the transmission belt 13 to run. The unloaded processed parts or edge materials are transported to the transmission belt 13 and move towards the tail end with the transmission belt 13. When the material moves to the push-separation unit 10 in the middle of the transmission unit, if it is a workpiece, the lifting cylinder 17 is activated, and its piston rod pushes the connecting piece 18 to slide upward along the slide rail 37 on the outer wall of the vertical plate 12 until the lower end of the separating piece 20 is higher than the workpiece. At this time, the workpiece is not obstructed and is transported to the next process through the workpiece conveying mechanism 3. If it is edge material, the horizontal plate 38 of the connector 18 drives the two separating cylinders 19 to move synchronously. The output end of the separating cylinder 19 pushes the push plate 21 to move towards the edge material cleaning mechanism 2. The front baffle 35 slides along the track 39 on the displacement seat 36 through the slide 50, blocking the subsequent material. The push plate 21 passes through the push port 34 at the upper end of the vertical plate 12 and pushes the edge material on the conveyor belt 13 to the input end of the edge material cleaning mechanism 2. After the edge material enters the edge material cleaning mechanism 2, it falls onto the conveyor frame 51. On the conveyor belt 52; the drive motor in the drive box 57 drives the chain disc 55 to rotate through the chain 56. The chain disc 55 is connected to the transmission roller, driving the conveyor belt 52 to move. The fan 59 is started and blows air downwards to blow off the waste on the surface of the edge material, which also has a cooling effect. Since the conveyor belt 52 has several through holes 53, the waste falls through the through holes 53 onto the first guide plate 60 or the second guide plate 65 below, and then falls into the collection box 62 through the opening 61 to complete the collection. The cleaned edge material is output with the conveyor belt 52. After the workpiece enters the unloading and lifting mechanism 5, it falls onto the unloading conveyor belt 67 on the unloading rack 66. The unloading conveyor belt 67 starts and transports upward. The two anti-jamming protrusions 69 on the inner side of the unloading rack 66 are located on both sides of the unloading conveyor belt 67 to prevent the unloading conveyor belt 67 from deviating or jamming during operation. The T-shaped limit block 80 at the rear end of the limit bar 79 restricts the limit bar 79 from swinging backward to prevent edge material from falling after passing through the limit bar 79. At the same time, the limit bar 79 will not obstruct the stop bar 68. After the workpiece is lifted to the top of the unloading rack 66 along with the unloading conveyor belt 67, it leaves the conveyor line and enters the next process, completing the entire die-casting machine unloading and conveying process.

The rear end of each limiting strip (79) has a T-shaped limiting block (80) connected to the extension seat (77). Each T-shaped limiting block (80) is used to limit the backward swing of the limiting strip (79).

10. The conveying method for unloading material from a die-casting machine as described in claim 9, characterized in that, include: Start the transmission motor (15) of the material distribution and transmission mechanism (1). The transmission motor (15) drives the transmission roller on the transmission base (11) to rotate through the chain, thereby driving the transmission belt (13) to run. The unloaded processed parts or edge materials are transported to the transmission belt (13) and move towards the tail end with the transmission belt (13). When the material moves to the push separation unit (10) in the middle of the transmission unit, if it is a workpiece, the lifting cylinder (17) is activated, and its piston rod pushes the connecting piece (18) to slide upward along the slide rail (37) on the outer wall of the vertical plate (12) until the lower end of the separation piece (20) is higher than the workpiece. At this time, the workpiece is not blocked, and the workpiece is transported to the next process through the workpiece conveying mechanism (3). If it is scrap material, the horizontal plate (38) of the connector (18) drives the two separating cylinders (19) to move synchronously. The output end of the separating cylinder (19) pushes the push plate (21) to move towards the scrap material cleaning mechanism (2). The front baffle (35) slides along the track (39) on the displacement seat (36) through the slide (50). The front baffle (35) blocks the subsequent material. The push plate (21) passes through the push port (34) at the upper end of the vertical plate (12) and pushes the scrap material on the conveyor belt (13) to the input end of the scrap material cleaning mechanism (2). After the scrap material enters the scrap material cleaning mechanism (2), it falls onto the conveyor frame (51). On the conveyor belt (52); the drive motor in the drive box (57) drives the chain disc (55) to rotate through the chain (56). The chain disc (55) is connected to the transmission roller, driving the conveyor belt (52) to move. The fan (59) is started and blows air downwards to blow off the waste on the surface of the edge material, which also has a cooling effect. Since the conveyor belt (52) has several through holes (53), the waste falls through the through holes (53) onto the first guide plate (60) or the second guide plate (65) below and then falls into the collection box (62) through the opening (61) to complete the collection. The cleaned edge material is output with the conveyor belt (52). After the workpiece enters the unloading lifting mechanism (5), it falls onto the unloading conveyor belt (67) on the unloading rack (66). The unloading conveyor belt (67) starts and transports upward. The two anti-jamming protrusions (69) on the inner side of the unloading rack (66) are located on both sides of the unloading conveyor belt (67) to prevent the unloading conveyor belt (67) from deviating or jamming during operation. The T-shaped limit block (80) at the rear end of the limit bar (79) restricts the limit bar (79) from swinging backward to prevent the edge material from falling after passing through the limit bar (79). At the same time, the limit bar (79) will not block the stop bar (68). After the workpiece is lifted to the top of the unloading rack (66) along with the unloading conveyor belt (67), it leaves the conveyor line and enters the next process, completing the entire die casting machine unloading and conveying process.
