Description

Technical Field

[0001] The present invention relates to a guiding device and its control method in the technical field of feeding control of a press. Background Art

[0002] With the in-depth development of industrial automation, the synchronous use of a feeder and a press has become increasingly frequent. After the existing feeder loads materials, the materials are sent into the feeding port of the press and then enter the die area, and the raw materials are processed and formed through the cooperation of the upper die and the lower die. However, when the feeder feeds materials into the press, due to reasons such as vibration, the raw materials sometimes shift, etc. It often requires manual intervention to straighten the raw materials so that they can be smoothly sent into the feeding port. This is both time-consuming and laborious, and there are certain safety hazards. Summary of the Invention

[0003] The purpose of the present invention is to provide an automatic secondary guiding device for coiled materials of a press and its control method, which does not require manual intervention during the production process, improves production efficiency, and ensures the effective organization of safe production.

[0004] To achieve the above purpose, the present invention provides an automatic secondary guiding device for coiled materials of a press, including a top mechanism. The top mechanism is equipped with an adjustment mechanism; the top mechanism includes an upper fixing seat, which is installed on the upper outer side of the feeding port of the press. A leveling plate is horizontally installed on the upper fixing seat, and the leveling plate is flush with the top of the feeding port of the press; the adjustment mechanism includes a fixed support seat, which is arranged on the lower outer side of the feeding port of the press. A longitudinal lifting mechanism is arranged at the bottom of the fixed support seat, and the longitudinal lifting mechanism is connected to a platform seat. A transverse guiding mechanism is arranged on the platform seat, and the platform seat matches the lower part of the discharging port of the feeder.

[0005] Compared with the prior art, the beneficial effect of the present invention is that the whole device is located between the press and the feeder. The platform seat is lifted to a height matching the feeding port of the feeder and the feeding port of the press through the longitudinal lifting mechanism, and then the transverse guiding mechanism is adjusted to a suitable position, so that the raw materials can pass through the transverse guiding mechanism and reach the feeding port of the press, avoiding the problem of left and right deviation during the movement of the raw materials. The leveling plate can prevent the raw materials from warping and can be smoothly sent into the feeding port. There is no need for manual intervention during the production process, which improves production efficiency and ensures the effective organization of safe production.

[0006] As a further improvement of the present invention, the longitudinal lifting mechanism includes a longitudinal lifting cylinder. The longitudinal lifting cylinder is connected to a longitudinal air path, and the longitudinal air path is connected to the main air path. The telescopic end of the longitudinal lifting cylinder is connected to the bottom of the platform seat. The fixed support seat is of an L-shaped structure. The tail of the longitudinal lifting cylinder is connected to the horizontal part of the bottom of the fixed support seat. Both sides of the platform seat are connected to the upper sides of both vertical parts of the fixed support seat via linear bearings. Limit blocks are also provided on both sides of the fixed support seat, and the limit blocks are located below the platform seat.

[0007] In this way, when the longitudinal lifting cylinder acts, it drives the platform seat to rise, so that the platform seat can reach a height that matches the feeding port of the feeder and the feeding port of the press. The platform seat is connected to the fixed support seat via linear bearings, and the limit blocks play a role in protecting the stroke limit.

[0008] As a further improvement of the present invention, the lateral guiding mechanism includes a positioning cylinder and an adjusting cylinder. The positioning cylinder is connected to a positioning air path, and the adjusting cylinder is connected to an adjusting air path. The positioning air path and the adjusting air path are connected to the main air path via a lateral one-way valve. The positioning cylinder and the adjusting cylinder are respectively arranged on both sides of the platform seat. The telescopic end of the positioning cylinder is connected to a positioning guide block, and the telescopic end of the adjusting cylinder is connected to an adjusting guide block. The positioning guide block and the adjusting guide block are respectively located on both sides of the feeding port of the press.

[0009] In this way, the two cylinders respectively push the corresponding guide blocks to move, and finally make the distance between the guide blocks slightly wider than the width of the raw material. When the raw material passes through between the guide blocks, it can basically move straight forward, avoiding large left and right offsets, so as to play a good guiding role.

[0010] As a further improvement of the present invention, the main air path includes an air source. The air source is connected to a main ball valve, the main ball valve is connected to a main filter, the main filter is connected to a main pressure relay, and the main pressure relay is connected to a main pressure gauge; A displacement sensor is provided on the adjusting cylinder. The adjusting cylinder is connected to an adjusting three-way solenoid valve. The adjusting three-way solenoid valve is equipped with an adjusting silencer. The adjusting three-way solenoid valve is connected to an adjusting speed control valve. The adjusting speed control valve is connected to an adjusting one-way valve. The adjusting one-way valve is connected to a lateral ball valve. The lateral ball valve is connected to the main pressure gauge; A displacement sensor is provided on the positioning cylinder. The positioning cylinder is connected to a positioning three-way solenoid valve. The positioning three-way solenoid valve is equipped with a positioning silencer. The positioning three-way solenoid valve is connected to a positioning speed control valve. The positioning speed control valve is connected to a positioning one-way valve. The positioning one-way valve is connected to a lateral ball valve. The lateral ball valve is connected to the main pressure gauge; A magnetic detection switch is set on the vertical lifting cylinder. The vertical lifting cylinder is connected to a vertical three-position five-way solenoid valve. The vertical three-position five-way solenoid valve is equipped with a vertical silencer. The vertical three-position five-way solenoid valve is connected to a vertical speed control valve. The vertical speed control valve is connected to a vertical one-way valve. The vertical one-way valve is connected to a vertical ball valve. The vertical ball valve is connected to a main pressure gauge.

[0011] In this way, the air can be filtered through the filter, the pressure relay can feedback the pressure information of the pipeline, the pressure gauge can observe the pressure state, and the three three-position five-way solenoid valves can independently control three branches to prevent the air circuit from flowing back. Three one-way valves are used to ensure the constancy of the air pressure, and the cylinder pressure is controlled through the ball valve and the speed control valve.

[0012] As a further improvement of the present invention, a photoelectric sensor is provided on the outer end of the horizontal part at the bottom of the fixed support seat.

[0013] In this way, the photoelectric sensor can be used to sense whether the transported material is sent out from the discharge port of the feeder.

[0014] In order to achieve the above object, the present invention also provides a control method for automatic secondary guiding of the coiled material of a press, including the following steps: Step 1, set the actual height of the fixed seat; Step 2, set the positions of the guiding block and the photoelectric sensor; Step 3, feed and guide the operation.

[0015] Compared with the prior art, the beneficial effect of the present invention is that according to the actual situation, the moving distance of the guiding block of the device and the rising height of the platform seat are preset in advance, and then the corresponding raw material is selected, and then the normal feeding operation is carried out according to the set mode, so that the raw material can be smoothly fed into the feeding port of the press, and no manual intervention is required during the production process, which not only improves the production efficiency but also ensures the effective organization of safe production.

[0016] As a further improvement of the present invention, the specific content of Step 1 is as follows: According to the height of the discharge port of the feeder, the height of the platform seat is adjusted by the action of the vertical lifting cylinder so that the height of the platform seat is the same as that of the discharge port. Then, this height is corresponded to the magnetic detection switch, so that during subsequent normal operation, when the vertical lifting cylinder drives the platform seat to rise to this height, it will automatically stop acting.

[0017] In this way, the rising height of the vertical lifting cylinder can be preset, so that when starting up and running, the platform seat can be automatically lifted to the set height and maintained unchanged, and only when the height of the discharge port of the feeder changes, it is preset and adjusted again.

[0018] As a further improvement of the present invention, the specific content of Step 2 is as follows: When the raw material is sent out from the discharge port of the feeder and always adheres to the left side of the discharge port and is sent out, the photoelectric sensor is set on the left side of the outer end of the bottom horizontal part of the fixed support seat, and the positioning cylinder is set on the left side of the platform seat, and the adjusting cylinder is set on the right side of the platform seat; then, according to the distance between the left guide block and the left side of the discharge port of the feeder, the value of the displacement sensor on the positioning cylinder is set, so that when the left guide block moves to a position 5 mm away from the left side of the discharge port of the feeder driven by the positioning cylinder, the positioning cylinder stops operating; finally, according to the width of the raw material, the moving distance of the displacement sensor on the adjusting cylinder on the right side is set. Therefore, if there are n kinds of raw materials with different widths, there will be n corresponding moving distances of the displacement sensor on the adjusting cylinder, and each moving distance will make the right guide block stop operating when it moves to a position 5 mm away from the right side of the raw material driven by the adjusting cylinder. In this way, one moving distance sets one working condition, and n moving distances set n working conditions; When the raw material is sent out from the discharge port of the feeder and always adheres to the right side of the discharge port and is sent out, the photoelectric sensor is set on the right side of the outer end of the bottom horizontal part of the fixed support seat, and the positioning cylinder is set on the right side of the platform seat, and the adjusting cylinder is set on the left side of the platform seat; then, according to the distance between the right guide block and the right side of the discharge port of the feeder, the value of the displacement sensor on the positioning cylinder is set, so that when the right guide block moves to a position 5 mm away from the right side of the discharge port of the feeder driven by the positioning cylinder, the positioning cylinder stops operating; finally, according to the width of the raw material, the moving distance of the displacement sensor on the adjusting cylinder on the left side is set. Therefore, if there are n kinds of raw materials with different widths, there will be n corresponding moving distances of the displacement sensor on the adjusting cylinder, and each moving distance will make the left guide block stop operating when it moves to a position 5 mm away from the left side of the raw material driven by the adjusting cylinder. In this way, one moving distance sets one working condition, and n moving distances set n working conditions.

[0019] In this way, the moving position of the positioning guide block and the installation position of the photoelectric sensor can be preset according to the actual situation, and then the moving working conditions of the adjusting guide block can be set according to raw materials of different specifications, so that the corresponding working conditions can be selected according to the situation of different raw materials. When changing raw materials, the operation is more convenient and simple.

[0020] As a further improvement of the present invention, the specific content of step 3 is as follows. Step 3.1, select the corresponding working condition according to the width of the raw material; Step 3.2, the raw material is sent out from the feeding port of the feeder, the photoelectric sensor senses the raw material and sends a signal to the controller, and the controller makes the feeder pause. Step 3.3, the adjusting cylinder operates, pushing the adjusting guide block to move towards the raw material until the moving distance reaches the value corresponding to the selected working condition and then stops moving. In step 3.4, the controller controls the feeder to act again, so that the raw material continues to move, passes through between the positioning guide block and the adjustment guide block, and enters the feed port of the press.

[0021] In this way, by selecting the corresponding working condition according to the actual situation, the raw material can be smoothly guided and transported to the feed port of the press, avoiding the problem of left - right deviation, and no manual intervention is required during the operation, which is convenient and simple to operate.

The positioning guide block 4 and the adjusting guide block 5 are respectively located on both sides of the feeding port of the press.

[0031] The main air path includes an air source 27, the air source 27 is connected to a main ball valve 28, the main ball valve 28 is connected to a main filter 29, the main filter 29 is connected to a main pressure relay 30, and the main pressure relay 30 is connected to a main pressure gauge 31.

[0032] A displacement sensor is arranged on the adjusting cylinder 6. The adjusting cylinder 6 is connected to an adjusting three-way solenoid valve 23. The adjusting three-way solenoid valve 23 is equipped with an adjusting silencer 24. The adjusting three-way solenoid valve 23 is connected to an adjusting speed control valve 25.

[0033] A displacement sensor is provided on the positioning cylinder 3. The positioning cylinder 3 is connected to the positioning three-way solenoid valve 18. The positioning three-way solenoid valve 18 is equipped with a positioning silencer 19. The positioning three-way solenoid valve 18 is connected to the positioning speed control valve 20.

[0035] Such as Figures 1-5 shown, a control method for automatic secondary guiding of coiled materials of a press includes the following contents. Step 1, set the actual height of the fixed seat. According to the height of the discharge port of the feeder, the height of the platform seat 7 is adjusted by the action of the longitudinal lifting cylinder 10 so that the height of the platform seat 7 is the same as the height of the discharge port. Then, this height is corresponded with the magnetic detection switch, so that during subsequent normal operation, when the longitudinal lifting cylinder 10 drives the platform seat 7 to rise to this height, it will automatically stop acting.

[0036] Step 2, set the positions of the guiding blocks and the photoelectric sensor 11. If the raw material is always sent out along the left side of the discharge port of the feeder when it is sent out from the discharge port of the feeder, then the photoelectric sensor 11 is set on the left side of the outer end of the bottom horizontal part of the fixed support seat 9, and the positioning cylinder 3 is set on the left side of the platform seat 7, and the adjusting cylinder 6 is set on the right side of the platform seat 7. Then, according to the distance between the left guiding block and the left side of the discharge port of the feeder, the value of the displacement sensor on the positioning cylinder 3 is set so that when the left guiding block moves to a position 5 mm away from the left side of the discharge port of the feeder driven by the positioning cylinder 3, the positioning cylinder 3 stops acting. Finally, according to the width of the raw material, the moving distance of the displacement sensor on the right adjusting cylinder 6 is set. Therefore, if there are n kinds of raw materials with different widths, there will be n corresponding moving distances of the displacement sensor on the adjusting cylinder 6. Each moving distance will make the right guiding block stop acting when it moves to a position 5 mm away from the right side of the raw material driven by the adjusting cylinder 6. In this way, one moving distance sets one working condition, and n moving distances set n working conditions. When the raw material is sent out from the discharge port of the feeder, if it always adheres to the right side of the discharge port and is sent out, then the photoelectric sensor 11 is set on the right side of the outer end of the horizontal part at the bottom of the fixed support base 9, and the positioning cylinder 3 is set on the right side of the platform base 7, and the adjusting cylinder 6 is set on the left side of the platform base 7; then, according to the distance between the right guide block and the right side of the discharge port of the feeder, the value of the displacement sensor on the positioning cylinder 3 is set, so that when the right guide block moves to a position 5 mm away from the right side of the discharge port of the feeder driven by the positioning cylinder 3, the positioning cylinder 3 stops operating; finally, according to the width of the raw material, the moving distance of the displacement sensor on the left adjusting cylinder 6 is set. Therefore, if there are n kinds of raw materials with different widths, there will be n corresponding moving distances of the displacement sensor on the adjusting cylinder 6, and each moving distance will cause the left guide block to stop moving when it moves to a position 5 mm away from the left side of the raw material driven by the adjusting cylinder 6. In this way, one moving distance sets one working condition, and n moving distances set n working conditions.

[0037] Step 3, feeding and guiding operation.

[0038] Step 3.1, select the corresponding working condition according to the width of the raw material; Step 3.2, the raw material is sent out from the feeding port of the feeder, the photoelectric sensor 11 senses the raw material and sends a signal to the controller, and the controller then makes the feeder pause. Step 3.3, the adjusting cylinder 6 operates, pushing the adjusting guide block 5 towards the raw material until the moving distance reaches the value corresponding to the selected working condition and then stops moving; Step 3.4, the controller controls the feeder to operate again, so that the raw material continues to move, passes through the space between the positioning guide block 4 and the adjusting guide block 5, and enters the feeding port of the press.

[0039] In the present invention, as Figures 1-4 shown, the top mechanism and the adjustment mechanism are connected to the press through fixing bolts to ensure the relative position between the device and the press remains unchanged. The top mechanism includes an upper fixing seat and a leveling plate 2 to ensure that the raw material does not jump when entering. The adjustment mechanism includes a platform base 7 and a fixed support base 9. The adjusting cylinder 6 and the positioning cylinder 3 are respectively arranged on both sides of the platform base 7. The adjusting cylinder 6 and the positioning cylinder 3 are respectively connected to the adjusting guide block 5 and the positioning guide block 4. After the raw material is sent out from the discharge port of the feeder, the two guide blocks move to the corresponding positions under the action of the cylinders, and the distance between the two guide blocks will position and guide the incoming raw material to ensure the position of the raw material remains unchanged.

[0040] A linear bearing 8 and a limit block 12 are arranged inside the fixed support base 9. The lifting of the platform base 7 is realized by adjusting the longitudinal lifting cylinder 10. The platform base 7 is connected to the fixed support base 9 through the linear bearing 8, and the limit block 12 plays a role in protecting the stroke limit. An optoelectronic sensor 11 is also arranged at the outer end of the horizontal part at the bottom of the fixed support base 9. When the raw material enters from above the optoelectronic sensor 11, it effectively feeds back that the raw material has been discharged.

[0041] As Figure 5 shown in the pneumatic circuit system, it includes a gas source 27 and a main ball valve 28 on the main air path, a main filter 29 for filtering air. The main air path is also provided with a main pressure relay 30 for electrically signaling and feedbacking the air pipeline pressure, and a main pressure gauge 31, which uses a shock-resistant pressure gauge to observe the pressure state. In order to achieve stable control of the device, the air pressure sizes of the main and branch circuits are respectively controlled independently by the main ball valve 28, the transverse ball valve 22, and the longitudinal ball valve 16. In order to achieve independent control of the cylinder air pressure, the longitudinal lifting cylinder 10, the adjusting cylinder 6, and the positioning cylinder 3 are respectively independently controlled by a longitudinal three-way solenoid valve 13, an adjusting three-way solenoid valve 23, and a positioning three-way solenoid valve 18; in order to prevent air path backflow, a longitudinal check valve 15, a positioning check valve 21, and an adjusting check valve 26 are adopted, so as to ensure the constancy of the air pressure. The pressure control of the three cylinders can be achieved not only through the longitudinal ball valve 16 and the transverse ball valve 22, but also through the longitudinal speed control valve 14, the positioning speed control valve 20, and the adjusting speed control valve 25.

[0042] During operation, the whole device is located between the press and the feeder. The rising height of the longitudinal lifting cylinder 10 is preset, so that when starting up and running, the platform base 7 can be automatically lifted to the set height and maintained unchanged. Only when the height of the discharge port of the feeder changes, it needs to be preset and adjusted again.

[0043] The moving position of the positioning guide block 4 and the installation position of the optoelectronic sensor 11 are preset according to the actual situation, and then the moving working conditions of the adjusting guide block 5 are set according to different specifications of raw materials, so that the corresponding working conditions can be selected according to the situation of different raw materials. When changing raw materials, the operation is more convenient and simple.

[0044] Select the corresponding working conditions according to the actual situation, and the raw materials can be smoothly guided and transported to the feed port of the press, avoiding the problem of left and right deviation, and no manual intervention is required during the operation process, and the operation is convenient and simple.

[0045] After the presetting is completed, start the machine formally, and select the corresponding working conditions according to the width of the raw material; The longitudinal lifting cylinder 10 operates to drive the platform seat 7 to rise, so that the platform seat 7 can reach a height that matches the feeding port of the feeder and the feeding port of the press. The platform seat 7 is connected to the fixed support seat 9 through a linear bearing 8, and the limit block 12 plays a role in protecting the stroke limit. The positioning cylinder 3 operates to drive the positioning guide block 4 to move a set distance and then stop; then the raw material is sent out from the feeding port of the feeder, and the photoelectric sensor 11 senses the raw material and sends a signal to the controller, and the controller then makes the feeder pause; the adjusting cylinder 6 operates to push the adjusting guide block 5 towards the raw material until the moving distance reaches the value corresponding to the selected working condition and then stops moving; the controller controls the feeder to operate again, so that the raw material continues to move, passes through between the positioning guide block 4 and the adjusting guide block 5, and enters the feeding port of the press.

[0046] During the production process of the present invention, no manual intervention is required, which not only improves the production efficiency but also ensures the effective organization of safe production.

The control method for automatic secondary guiding of coils of a press according to claim 6, characterized in that: The specific contents of step 1 are as follows: according to the height of the discharge port of the feeder, the height of the platform seat is adjusted by the longitudinal lifting cylinder so that the height of the platform seat is consistent with the height of the discharge port. Then, the height is matched with the magnetic detection switch so that during subsequent normal operation, the longitudinal lifting cylinder drives the platform seat to rise to this height and then automatically stops.

8. The control method for automatic secondary guiding of coils of a press machine according to claim 7, characterized in that: The specific contents of step 2 are as follows: If the raw material is always sent out in contact with the left side of the discharge port when it is sent out from the discharge port of the feeder, then the photoelectric sensor is set on the left side of the outer end of the bottom horizontal part of the fixed support seat, and the positioning cylinder is set on the left side of the platform seat, and the adjusting cylinder is set on the right side of the platform seat; then according to the distance between the left guide block and the left side of the discharge port of the feeder, the value of the displacement sensor on the positioning cylinder is set, so that when the left guide block is driven by the positioning cylinder to move to 5mm to the left side of the discharge port of the feeder, the positioning cylinder stops; finally, according to the width of the raw material, the moving distance of the displacement sensor on the right adjusting cylinder is set. Therefore, if there are n kinds of raw materials of different widths, there will be n corresponding moving distances of the displacement sensor on the adjusting cylinder, and each moving distance will cause the right guide block to stop moving when it is driven by the adjusting cylinder to move to 5mm from the right side of the raw material, so that one moving distance sets one working condition, and n moving distances set n working conditions; If the raw material is always sent out from the discharge port of the feeder in line with the right side of the discharge port, then the photoelectric sensor is set on the right side of the outer end of the bottom horizontal part of the fixed support seat, and the positioning cylinder is set on the right side of the platform seat, and the adjusting cylinder is set on the left side of the platform seat; then according to the distance between the right guide block and the right side of the discharge port of the feeder, the value of the displacement sensor on the positioning cylinder is set, so that when the right guide block moves to 5mm to the right side of the discharge port of the feeder under the drive of the positioning cylinder, the positioning cylinder stops moving; finally, according to the width of the raw material, the moving distance of the displacement sensor on the left adjusting cylinder is set. Therefore, if there are n kinds of raw materials of different widths, there will be n corresponding moving distances of the displacement sensor on the adjusting cylinder, and each moving distance will cause the left guide block to stop moving when it moves to 5mm from the left side of the raw material under the drive of the adjusting cylinder. In this way, one moving distance sets one working condition, and n moving distances set n working conditions.

9. A method for controlling the automatic secondary guiding of coils of a press according to claim 8, characterized in that: The specific contents of step 3 are as follows: Step 3.1, select the corresponding working conditions according to the width of the raw material; Step 3.2, the raw material is fed out from the feeding port of the feeder, the photoelectric sensor senses the raw material and sends a signal to the controller, and the controller stops the feeder; Step 3.3, adjust the cylinder action to push the adjustment guide block toward the raw material until the moving distance reaches the value corresponding to the selected working condition and then stop moving; In step 3.4, the controller controls the feeder again so that the raw material continues to move, passes between the positioning guide block and the adjusting guide block, and enters the feed port of the press.
