Description

TECHNICAL FIELD

[0001] The present application relates to the field of presses, in particular to a press waste conveying device. BACKGROUND

[0002] As the core equipment in metal stamping and forming processing, presses are widely used in the manufacturing industry of automobile parts, home appliance hardware, electronic components, etc. During the stamping process of the press, metal waste (such as corner scraps, blanking waste, etc.) is continuously generated. If these waste materials cannot be timely and orderly processed, not only will they occupy the production site and affect the cleanliness of the workshop environment, but also may cause the press die to be stuck, the stamping precision to be reduced, and even equipment failure or safety accidents to the operators. Therefore, an efficient and stable waste conveying system is a key supporting equipment for the automatic operation of the press production line.

[0003] Currently, the industry mainly uses the following two technical solutions to process press waste, but both have obvious limitations.

[0004] 1. Manual cleaning method: relying on the operator to clean the waste from the workbench to the waste basket during the press stamping interval, and then manually transporting it to the centralized recycling point. ① The degree of automation is extremely low, and a dedicated person is needed, which is high in labor cost; ② The cleaning needs to be done when the press is stopped or running at low speed, interrupting the production process and reducing the overall efficiency of the production line; ③ The operator needs to be close to the high-speed running press, which has safety hazards such as hand injury and waste splashing.

[0005] 2. Conventional belt conveyor conveying method: the motor drives the belt to run, continuously conveying the waste generated by the press to the remote collection point. The belt is easily worn and deviated by metal waste, and needs to be frequently replaced and adjusted, which is a large maintenance workload.

[0006] In view of the above related technologies, the inventors propose a new press waste conveying device. SUMMARY

[0007] In order to improve the above problems, the present application provides a press waste conveying device.

[0008] The press waste conveying device provided by the present application adopts the following technical solution:

[0009] A press waste conveying device, comprising:

[0010] a support frame;

[0011] a conveying plate, the conveying plate is inclinedly arranged, the conveying plate has a feeding end and a discharging end, the feeding end of the conveying plate is rotationally connected with the support frame, one end of the conveying plate with a higher position is the feeding end, and one end of the conveying plate with a lower position is the discharging end;

[0012] The centralized material collecting and discharging mechanism has the effect of collecting waste materials and then discharging them;

[0013] The telescopic mechanism is hinged at one end to the support frame and at the other end to the lower end of the conveying plate, and is used to drive the conveying plate to swing;

[0014] The centralized material collecting and discharging mechanism includes a rotating shaft, which is rotatably connected to the support frame, and a plurality of hoppers are formed on the rotating shaft in the circumferential direction of the rotating shaft; a plurality of elastic protrusions are arranged on the rotating shaft corresponding to the hoppers; a limiting piece is fixed on the support frame; the elastic protrusions abut against the limiting piece, and after the hoppers collect waste materials, the rotating shaft rotates with the elastic protrusions due to the gravity of the hoppers overcoming the resistance of the limiting piece, so that the hoppers dump the waste materials to the feeding end of the conveying plate.

[0015] By adopting the above technical scheme, the waste materials are automatically conveyed after being collected in a centralized manner; the telescopic mechanism is used to drive the conveying plate to rotate; the conveying plate is inclined to rely on the self-weight of the waste materials to slide and convey; the telescopic mechanism can adjust the inclination angle of the conveying plate to achieve the best conveying effect.

[0016] The telescopic mechanism is in a retracted state during the waste material discharging process, so that the inclination angle of the conveying plate is larger and the waste materials are less likely to be jammed; when the waste materials accelerate to slide close to the lower end, the telescopic mechanism is extended, and at this time, the inclination angle of the conveying plate is reduced, so that the inclination angle of the conveying plate is reduced, and the conveying plate has a longer horizontal length, so that the waste materials are conveyed farther away from the centralized material collecting and discharging mechanism (punching machine), and the safety is higher. Moreover, due to the intermittent movement of the telescopic mechanism, jamming will not occur. Here, jamming refers to the situation that the waste materials cannot slide due to large friction between the waste materials and the conveying plate. The multi-hopper design can collect waste materials in batches, avoid the scattering of waste materials discharged from the press as production proceeds, and reduce the workload of frequent manual cleaning; the gravity triggering mechanism (the rotating shaft is rotated after the hopper is filled with waste materials) of the elastic protrusions and the limiting piece realizes automatic discharging of the waste materials to the conveying plate without manual intervention, greatly improves the automation degree of the material collecting link, and has low energy consumption.

[0017] Optionally, the contact surface of the elastic protrusions and the limiting piece is an arc surface, and the position of the arc surface when the hopper stops forms a buffer portion abutting against the limiting piece.

[0018] By adopting the above technical scheme, the arc surface design can convert rigid abutment into smooth contact, reduce the friction loss of the elastic protrusions and the limiting piece, and prolong the service life of the components; the buffer portion precisely abuts against the limiting piece when the hopper stops, can absorb the impact force when the hopper rotates, avoids noise caused by collision, and ensures that the hopper stays at the preset material collecting position to prevent discharging deviation.

[0019] Optionally, a one-way rotation structure is arranged between the rotating shaft and the support frame, so that the hopper above the rotating shaft can only rotate towards the conveying plate.

[0020] By adopting the above technical scheme, the hopper above the rotating shaft can only rotate towards the conveying plate, which prevents the hopper from reversing due to vibration or accidental touch, ensures that the waste is always accurately unloaded into the feeding end of the conveying plate, and reduces waste and secondary cleaning costs.

[0021] Optionally, a blocking device is fixed on the support frame, the blocking device comprises a transmission shaft rotatably connected with the support frame, a cam portion mounted on the transmission shaft, and a blocking plate movably matched with the cam portion; the transmission shaft is linked with the rotating shaft through a transmission structure; the support frame forms a mounting portion for mounting the blocking plate, and a slow-release reset mechanism for slowly resetting the blocking portion is mounted in the mounting portion.

[0022] By adopting the above technical scheme, the blocking plate mainly ensures that the hopper only rotates one station each time, that is, after the previous hopper is fully collected and then unloaded, another empty hopper is located below the unloading port of the press, and the transmission structure is used to realize the operation of the blocking device without the need for other control devices.

[0023] Optionally, the slow-release reset mechanism comprises an elastic reset member and a damping member, one end of the elastic reset member is connected with the mounting portion, and the other end is connected with the blocking plate, and the damping member is located on the extension path of the elastic reset member.

[0024] Optionally, the transmission structure is one of belt transmission, chain transmission and gear transmission.

[0025] By adopting the above technical scheme, the three transmission modes have their own advantages: belt transmission has low noise and low cost (suitable for light load working conditions); chain transmission has high load capacity and wear resistance (suitable for heavy load working conditions); gear transmission has high precision and high efficiency (suitable for working conditions with high synchronization requirements);

[0026] Optionally, a movable plate is hinged at the discharging end of the conveying plate, a guide plate is fixedly connected to the support frame, the inner side surface of the guide plate is an arc surface, the center of the arc surface coincides with the rotation point of the conveying plate and the support frame, a limiting rod is fixed to the conveying plate, and the limiting rod is located on the inner side of the conveying plate relative to the movable plate; the movable plate tends to be perpendicular to the conveying plate during the downward swinging of the conveying plate.

[0027] By adopting the technical scheme, when the conveying plate is lowered, the arc surface (the center of which coincides with the rotating point of the conveying plate) of the guide plate can keep the movable plate between the guide plate and the limiting rod, and the movable plate tends to be perpendicular to the conveying plate. In this way, even if the waste material slides down too fast, it will be blocked by the movable plate, and after the movable plate is not limited by the guide plate during the lifting of the conveying plate, the movable plate will be flipped outward due to its own gravity and the pushing force of the waste material, and the waste material will pass over the movable plate and enter the collecting box.

[0028] Optionally, the telescopic mechanism is one of an electric push rod, an air cylinder and an oil cylinder.

[0029] By adopting the technical scheme, the three telescopic mechanisms are suitable for different working conditions: the electric push rod has high control precision and no oil stains (suitable for light load / clean workshop); the air cylinder has fast response and low cost (suitable for medium / light load / high-frequency adjustment working condition); and the oil cylinder has large pushing force and high pressure resistance (suitable for heavy load / large-angle adjustment working condition, such as thick plate waste material conveying).

[0030] Optionally, a locking mechanism for locking the centralized material collecting and discharging mechanism is further installed on the support frame, the locking mechanism comprises a locking rod and an operating rod, the middle part of the operating rod is hinged to the support frame, the locking rod is provided with a through slot, the upper end of the operating rod passes through the through slot, a compression spring is installed between the locking rod and the support frame, and a lock slot is formed in the rotating shaft corresponding to the locking rod, and a plurality of lock slots are arranged corresponding to the hoppers.

[0031] By adopting the technical scheme, when the equipment is maintained (such as cleaning the hopper and overhauling the rotating shaft) or stopped, the locking rod can be clamped into the lock slot of the rotating shaft to prevent the rotating shaft from rotating accidentally (to avoid the hopper from falling or the waste material from hurting people), and the safety hazard is eliminated.

[0032] The plurality of lock slots correspond to the plurality of hoppers, the rotating shaft can be locked at any hopper position, targeted overhauling (such as cleaning only one blocked hopper) is facilitated, the operating rod is easily unlocked through the lever principle, the compression spring ensures that the locking rod can be reliably clamped, and safety and operation efficiency are considered.

[0033] Optionally, a controller is further installed on the support frame, and the controller is used to control the action of the telescopic mechanism.

[0034] By adopting the technical scheme, the controller can preset parameters, such as automatically controlling the telescopic mechanism to work according to the punching frequency of the press machine, or adjusting in real time through sensor feedback (such as the waste material accumulation amount of the conveying plate).

[0035] In summary, the present application has at least one of the following beneficial technical effects:

[0036] 1. By centrally collecting waste material through the hopper, the working frequency of the telescopic mechanism can be reduced.

[0037] 2. The centralized material receiving and discharging mechanism realizes automatic material receiving and discharging by means of multiple hoppers and gravity of waste materials, and has no energy consumption.

[0038] 3. The centralized material discharging and the swing setting of the conveying plate can prevent material blockage. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0048] The present application will be further described below in conjunction with the accompanying drawings. Figures 1-8

[0049] Embodiment 1: The present application discloses a press waste conveying device. It comprises a support frame 1, a conveying plate 2, a centralized material receiving and discharging mechanism, and a telescopic mechanism 11. ​​​​​

[0050] The support frame 1 is an aluminum profile skeleton structure or a stainless steel skeleton structure, which is high at one end and low at the other end. The cross section of the conveying plate 2 is U-shaped, and the conveying plate 2 has side plates on both sides.

[0051] The conveying plate 2 is arranged obliquely, and the conveying plate 2 has a feeding end and a discharging end. The end of the conveying plate 2 that is higher in position is the feeding end, and the end of the conveying plate 2 that is lower in position is the discharging end; the feeding end of the conveying plate 2 is rotationally connected with the support frame 1.

[0052] The centralized material collecting and discharging mechanism has the effect of collecting waste materials and then discharging. The centralized material collecting and discharging mechanism comprises a rotating shaft 3 rotationally connected with the support frame 1, and a plurality of hoppers 4 are formed on the rotating shaft 3 in the circumferential direction of the rotating shaft 3. The hopper 4 has a large opening and a small bottom. In this application, the end of the rotating shaft 3 has a hollow groove, and a plurality of elastic protrusions 5 are arranged on the rotating shaft 3 corresponding to the hoppers 4, that is, one hopper 4 corresponds to one elastic protrusion 5. The elastic protrusions 5 are uniformly distributed in the hollow groove along the circumferential direction of the rotating shaft 3, and the elastic protrusions 5 are mainly made of rubber material. A limiting piece 6 is fixed on the support frame 1, and the limiting piece 6 comprises a shaft part 7 inserted into the hollow groove and a limiting part 8 integrally formed with the shaft part 7. The shaft part 7 is a cylindrical structure coaxial with the rotating shaft 3. The contact surface between the elastic protrusion 5 and the limiting piece 6 is an arc surface, and the position of the arc surface when the hopper 4 stops forms a buffer part 9 abutting against the limiting piece 6. The buffer part 9 is integrally formed with the elastic protrusion 5, and the cross section of the buffer part 9 is a figure close to a semicircle. In order to facilitate the deformation of the elastic protrusion 5, a deformation groove 10 is formed at the position close to the end of the elastic protrusion 5.

[0053] When the elastic protrusion 5 abuts against the limiting piece 6 and after the hopper 4 collects waste materials, the rotating shaft 3 rotates with the elastic protrusion 5 overcoming the resistance of the limiting piece 6 due to the gravity of the hopper 4, so that the hopper 4 pours the waste materials to the feeding end of the conveying plate 2.

[0054] A one-way rotation structure is arranged between the rotating shaft 3 and the support frame 1, so that the hopper 4 above the rotating shaft 3 can only rotate towards the conveying plate 2. The one-way rotation structure can be a ratchet structure, and a one-way bearing (not shown in the figure) is used in this embodiment; that is, the inner ring of the one-way bearing is in interference fit with the rotating shaft 3, and the outer ring is in interference fit with the bearing mounting hole on the support frame 1.

[0055] The telescopic mechanism 11 is hinged at one end to the support frame 1 and at the other end to the discharging end of the conveying plate 2, and is used to drive the conveying plate 2 to swing; the telescopic mechanism 11 is one of an electric push rod, an air cylinder and an oil cylinder. An air cylinder is used in this application; that is, the cylinder body of the air cylinder is hinged to the support frame 1, and the telescopic rod of the air cylinder is hinged to the lower part of the conveying plate 2 close to the discharging end.

[0056] The support frame 1 is further provided with a locking mechanism for locking the centralized material loading and unloading mechanism, which comprises a locking rod 12 and an operating rod 13, the middle part of the operating rod 13 is hinged to the support frame 1, the locking rod 12 is provided with a through slot 14, the upper end of the operating rod 13 passes through the through slot 14, a compression spring 15 is arranged between the locking rod 12 and the support frame 1, the rotating shaft 3 is provided with a locking slot 16 corresponding to the locking rod 12, and a plurality of locking slots 16 are arranged corresponding to the hoppers 4, i.e. one hopper 4 is provided with one locking slot 16.

[0057] The lower end of the conveying plate 2 is hinged with a movable plate 17, the support frame 1 is fixedly connected with a guide plate 18, the inner side of the guide plate 18 is an arc surface, and the center of the arc surface coincides with the rotating point of the conveying plate 2 and the support frame 1. The conveying plate 2 is fixedly connected with a limiting rod 19, the limiting rod 19 is located on the inner side of the conveying plate 2 relative to the movable plate 17; the movable plate 17 tends to be perpendicular to the conveying plate 2 during the downward swinging of the conveying plate 2, and the outer side of the movable plate 17 abuts against the arc surface and is located above the conveying plate 2 during the downward swinging of the conveying plate 2.

[0058] The support frame 1 is further provided with a controller 20 for controlling the action of the telescopic mechanism 11, generally, the controller 20 works in cooperation with a sensor, for example, a pressure sensor 21 is arranged on the upper surface of the conveying plate 2, and the pressure sensor 21 is generally arranged at the middle position between the middle part and the lower end of the conveying plate 2. When the waste falls, the inclination of the conveying plate 2 is the largest, at this time, the telescopic mechanism 11 is in the contracted state. One side of the movable plate 17 is limited between the guide plate 18 and the limiting rod 19, and the movable plate 17 is basically perpendicular to the conveying plate 2, at this time, even if the waste is not detected by the pressure sensor 21, it will also be blocked by the movable plate 17. Since the present scheme adopts the centralized material loading mode, when the waste is detected by the pressure sensor 21, the telescopic mechanism 11 immediately makes the stretching action to the maximum through the controller 20, at this time, the movable plate 17 is higher than the guide plate 18 and is turned outward and swings downward under the gravity of the movable plate 17 to abut against the outer wall of the guide plate 18, and the waste enters the waste collecting box without the limitation of the movable plate 17. The sensor can also be an angle sensor arranged on the rotating shaft 3. The sensor can also not be arranged, and the telescopic mechanism 11 is preset to stretch and contract at intervals according to the working capacity of the press. Since the amount of waste to be lowered is determined, and the carrying capacity of the hopper 4 can also be calculated, the telescopic mechanism 11 can be preset to stretch and contract at intervals in the controller 20.

[0059] The embodiment 2 is based on the embodiment 1, and a blocking device is additionally fixed on the support frame 1. The blocking device comprises a transmission shaft 22 rotationally connected with the support frame 1, a cam portion 27 installed on the transmission shaft 22, and a blocking plate 28 cooperatively moved with the cam portion 27. The transmission shaft 22 is linked with the rotating shaft 3 through a transmission structure 23. The transmission structure 23 is one of a belt transmission, a chain transmission, and a gear transmission. In this embodiment, the belt transmission is adopted. The belt wheel of the belt transmission is a toothed belt wheel, so that the transmission synchronization is good.

[0060] The support frame 1 forms a mounting portion 24 for mounting the blocking plate 28. A slow-release reset mechanism for driving the blocking portion to slowly reset is mounted in the mounting portion 24. The slow-release reset mechanism comprises an elastic reset member 25 and a damping member 26. One end of the elastic reset member 25 is connected with the mounting portion 24, and the other end is connected with the blocking plate 28. The damping member 26 is located on the extension path of the elastic reset member 25. In this embodiment, the elastic reset member 25 is a spring. One end of the spring is connected with the mounting portion 24, and the other end is connected with the blocking plate 28. The damping member 26 can be a hydraulic damper, in which case the spring is sleeved outside the hydraulic damper. The damping member 26 can also be a friction sleeve, in which case the spring is sleeved outside the friction sleeve. When the spring is compressed, the spring is in contact with the outer wall of the friction sleeve, so that the spring slowly resets due to the friction between the spring and the friction sleeve.

[0061] When the uppermost hopper 4 collects waste, the rotating shaft 3 rotates due to the gravity of the hopper 4 overcoming the resistance of the limiting member 6. The hopper 4 dumps waste to the feeding end of the conveying plate 2. After the hopper 4 rotates, the blocking plate 28 extends and is inserted into the hopper 4. The blocking plate 28 abuts against the upper plate of the hopper 4, thereby limiting the hopper 4 from continuously rotating, ensuring that the next hopper 4 (empty hopper 4) can replace the position of the previous hopper 4. The function of the blocking plate 28 is similar to that of the buffer portion 9, and the blocking plate 28 and the buffer portion 9 are generally shared. In this way, it is ensured that the hopper 4 can replace the position of the hopper 4 after the hopper 4 dumps waste each time. The hopper 4 one and the hopper 4 two are both the hopper 4. The hopper 4 one and the hopper 4 two are only used for convenient expression and understanding.
