Description

Technical Field

[0001] The invention relates to the technical field of automatic material dividing and feeding of screw machines, and in particular to a rotary disc material dividing device for screw machines. Background Art

[0002] A screw machine is a tool or equipment used to automatically tighten screws or bolts. It usually includes main parts such as an electric drive system and an automatic feeding system. The commonly used automatic feeding system is a turntable feeder, which can arrange the screws neatly and transport them to the feeding part of the screw machine.

[0003] At present, the turntable material dividing and feeding machine arranges the screws neatly by the rotation and vibration of the turntable, and then feeds the screws to the screw machine through the moving slide. The announcement number CN109335594B discloses a vibrating disc screw feeder, which includes a machine fixing plate, a bottom plate, a vibrating disc base, a disc cover plate, a cover plate bracket, a front cover group, a front section material dividing mechanism, a disc group, a rear cover group and a pressing plate group. The pressing plate group includes a transparent pressing plate, a pressing plate connecting plate, a micro switch, a pressing plate bracket, a spring hinge, a cover plate, and a pressing plate fixing seat.

[0004] The above-mentioned vibration disc screw feeder adopts a precision vibration disc base with stable vibration. The disc and track are installed on the upper part of the entire machine. There is no obstruction above, and the entire feeding process is visible. The jamming point can be observed intuitively, and the screws in the disc are easy to remove, which speeds up the replacement of screws. The pressing plate adopts a flip-up type. When a jam occurs, the pressing plate can be directly opened to remove the jammed screws. The front-end dividing mechanism adopts a groove wheel mechanism with four-division precise positioning, and when a jam occurs, the motor can be reversed. The entire machine structure is simple, easy to assemble, and later maintenance and repair are convenient and quick.

[0005] However, when the vibrating disc screw feeder is used, the neatly arranged screws vibrated by the vibrating disc will slide in the groove. Since the sliding thrust is provided by the pressure of the screws at the rear and the groove is inclined at an angle, the gravity separation in the horizontal direction will provide thrust to make the screws slide in the groove. This will cause the screws in the vibrating disc to accumulate at the front end entering the groove, resulting in reduced feeding efficiency. At the same time, some unqualified screws will also be fed to the screw machine through the groove, and unqualified screws will also cause blockage in the groove. In addition, unqualified screws cannot be removed, affecting the normal operation of the screw machine.

[0006] Therefore, a novel screw machine turntable material dividing device can be adopted to solve the shortcomings of the prior art. Summary of the invention

[0016] Preferably, the chain is composed of multiple chain links, and the transmission assembly includes a mounting block installed between two adjacent chain links, each chain link is rotatably connected to the mounting block, a support rod is fixedly mounted on the mounting block, a material receiving plate is rotatably mounted on the support rod, a reset mechanism is installed between the material receiving plate and the support rod, and a limiting mechanism that cooperates with the corresponding multiple material receiving plates is installed on the mounting frame.

[0017] Preferably, the reset mechanism comprises a baffle fixedly mounted on the support rod, and a plurality of arc springs are fixedly mounted between the baffle and the receiving plate.

[0018] Preferably, the limiting mechanism comprises two support rods fixedly mounted on the mounting frame, and a limiting stopper rod cooperating with the material receiving plate is fixedly mounted on the two support rods, and the end of the limiting stopper rod away from the vibration plate is in an inverted trapezoidal shape.

[0019] Preferably, the detection component includes a detection bracket fixedly mounted on the material transfer bracket, a detection probe fixedly mounted on the detection bracket, a sensor controller fixedly mounted on the detection probe, and two sets of unloading mechanisms cooperating with corresponding material receiving plates are mounted on the detection bracket.

[0020] Preferably, the unloading mechanism comprises an electric push rod fixedly mounted on the detection bracket, the electric push rod is electrically connected to the sensor controller, and a push plate matching with a material receiving plate is fixedly mounted on the telescopic end of the electric push rod.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. When the screw machine rotary table material distribution device is performing the screw supply operation, the neatly arranged screws on the vibration plate can be transmitted by setting the chain, the mounting block and the receiving plate. Since the chain operates smoothly and will not get stuck, and the use of the arc spring can enable the two receiving plates to clamp and transport the screws to prevent the screws from falling and reduce the probability of blockage in the screw transportation.

[0024] 3. When the screw machine rotary table dividing device is performing the screw feeding operation, a detection probe is set to monitor the quality of the screws in the transportation process, mainly to detect the appearance defects of the screws, and then the electric push rod drives the push plate to move, and the push plate drives the receiving plate to rotate, thereby expanding the distance between the two receiving plates, so that the screws clamped between the two receiving plates fall from the receiving plates, and the screws with appearance defects can be divided and screened to prevent defective screws from entering the feeding area. At the same time, with the use of the limit stopper, the receiving plate can be automatically rotated when the receiving plate rotates to the bottom, so that the distance between the two receiving plates is larger than the size of the screw, thereby preventing the screw from falling onto the receiving plate at the bottom and causing the receiving plate to be stuck.

[0025] In summary, the present invention uses chains and receiving plates to transport the arranged screws, which not only has high stability, but also reduces the probability of screw blockage. In addition, screws of different sizes can be transported by changing the spacing between the receiving plates, thereby expanding the scope of application. At the same time, the screws in transit can be inspected and removed to ensure that the screws transported to the screw machine for use are all qualified products in appearance, thereby ensuring the normal operation of the screw machine.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Example 1: Reference Figure 1-Figure 3 , a screw machine turntable material distribution device, including a vibration plate 3 and a screw 13, and also includes a material transfer bracket 6 fixedly mounted on the vibration plate 3;

[0045] The vibration plate 3 can automatically bring the screws 13 at the bottom of the vibration plate 3 to the top of the vibration plate 3 through vibration and rotation, and arrange them neatly. This is an existing feeding arrangement device, and its working principle will not be specifically described here.

[0046] The driving part is installed at the bottom of the vibration plate 3, and is used to drive the vibration plate 3 to rotate and also drive the vibration plate 3 to vibrate. The bottom of the vibration plate 3 is installed with a chassis 2 through a driving component, and a plurality of legs 1 are fixedly installed at the bottom of the chassis 2.

[0047] The driving assembly includes a motor 7 fixedly mounted on the upper part of the chassis 2, a driving end of the motor 7 being slidably connected to the vibration disk 3, a plurality of vibration rocker arms 4 being rotatably mounted on the chassis 2, a vibration sleeve being commonly mounted on the plurality of vibration rocker arms 4, each vibration rocker arm 4 being rotatably connected to the vibration sleeve, and a driving motor matching the plurality of vibration rocker arms 4 being mounted inside the chassis 2.

[0048] The driving motor drives the vibration rocker arm 4 to rotate back and forth rapidly, thereby driving the vibration sleeve to rotate. While the vibration sleeve rotates, it also moves back and forth up and down, thereby driving the vibration disk 3 to move back and forth up and down to produce a vibration effect. At the same time, the motor 7 drives the vibration disk 3 to rotate. The reason for the sliding connection between the vibration disk 3 and the driving end of the motor 7 is to reduce the impact of the up and down vibration of the vibration disk 3 on the motor 7, thereby ensuring the operating efficiency of the motor 7.

[0049] A boss 5 is fixedly installed at the bottom of the vibration disk 3. The cross-sectional shape of the boss 5 is truncated cone-shaped, and the bottom of the vibration disk 3 is truncated cone-shaped. The function of the boss 5 and the truncated cone-shaped bottom of the vibration disk 3 is to make the screws 13 in the vibration disk 3 close to the inner wall of the vibration disk 3, which can effectively improve the arrangement efficiency of the screws 13.

[0050] Embodiment 2: The technical solution of this embodiment is different from that of Embodiment 1 in that, referring to Figure 1-Figure 6 , Fig.12The material transfer part is installed on the material transfer bracket 6 and is used in conjunction with the vibration plate 3 to transfer the neatly arranged screws 13 of the vibration plate 3 to the feeding part. The material transfer part includes two mounting frames 8 slidably installed on both sides of the material transfer bracket 6 through multiple limit sliding columns 9, and a linkage component is installed between the two mounting frames 8.

[0051] The linkage assembly includes a fixed frame 27 fixedly mounted on the bottom of the material transfer bracket 6, and a gear cylinder 28 is rotatably mounted on the fixed frame 27. A tooth plate 15 meshing with the gear cylinder 28 is fixedly mounted on one of the mounting frames 8, and a tooth plate 26 meshing with the gear cylinder 28 is fixedly mounted on the other mounting frame 8. The tooth plate 26 and the tooth plate 15 are respectively located on the upper and lower sides of the gear cylinder 28, and a one-way locking mechanism matching the gear cylinder 28 is installed on the fixed frame 27.

[0052] The rotation of the gear cylinder 28 will drive the tooth plate 1 15 and the tooth plate 2 26 to move in different directions. The tooth plate 1 15 and the tooth plate 2 26 will drive the corresponding mounting frame 8 to move in different directions, thereby driving the chain 12 and the receiving plate 19 to move. This can change the distance between the corresponding receiving plates 19 on the two chains 12, thereby achieving the purpose of clamping and transporting screws 13 of different sizes. It is suitable for screws 13 of different sizes and has high stability during transportation.

[0053] The one-way locking mechanism includes a rotating shaft fixedly mounted on the gear cylinder 28, the central axis of the rotating shaft and the central axis of the gear cylinder 28 are located on the same horizontal line, the rotating shaft and the fixed frame 27 are rotatably connected, the ratchet 16 is fixedly mounted on the rotating shaft, a rotating shaft 29 is rotatably mounted on the fixed frame 27, a clamping rod 31 matching the ratchet 16 is slidably mounted on the rotating shaft 29, a spring roll 30 is fixedly mounted between the rotating shaft 29 and the fixed frame 27, the spring roll 30 can ensure that the clamping rod 31 is always stuck in the tooth groove of the ratchet 16, and a pull rod 32 is fixedly mounted on the clamping rod 31.

[0054] When the pull rod 32 is pulled, the clamping rod 31 will be driven to move on the rotating shaft 29, thereby disengaging the clamping rod 31 from the ratchet 16. The ratchet 16 loses the restriction of the clamping rod 31 and can rotate freely. If the ratchet 16 needs to be limited, the pull rod 32 can be pushed to insert the clamping rod 31 into the tooth groove of the ratchet 16 to lock the ratchet 16. When the ratchet 16 is locked, the gear cylinder 28 can still rotate, but the rotation direction is limited. At this time, the gear cylinder 28 rotates, and the tooth plate 15 and the tooth plate 26 will only move to the side close to each other. Due to the restriction of the screw 13, the tooth plate 15 and the tooth plate 26 will not move, and will not affect the overall operation. This design can effectively reduce the impact of mechanical vibration.

[0055] Embodiment 3: The technical solution of this embodiment is different from that of Embodiment 2 in that, referring to Figure 4-Figure 10 , Figure 13-Figure 15Two shafts are rotatably mounted on the two mounting frames 8, and a motor 2 10 is fixedly mounted on the two mounting frames 8. The driving ends of the two motors 2 10 are fixedly connected to the corresponding shafts respectively. A toothed disc 17 is fixedly mounted on each shaft. A chain 12 is commonly sleeved between the two mutually cooperating toothed discs 17, and a transmission component cooperating with a screw 13 is installed on the chain 12.

[0056] The chain 12 is composed of multiple chain links, and the transmission assembly includes a mounting block 18 installed between two adjacent chain links. Each chain link is rotatably connected to the mounting block 18. A support rod 21 is fixedly installed on the mounting block 18, and a material receiving plate 19 is rotatably installed on the support rod 21. A reset mechanism is installed between the material receiving plate 19 and the support rod 21.

[0057] The driving end of the motor 2 10 rotates to drive the shaft body to rotate, and the rotation of the shaft body drives the toothed disc 17 to rotate, thereby driving the chain 12 to rotate, and the rotation of the chain 12 will drive the mounting block 18 and the receiving plate 19 to rotate, thereby realizing the transportation of the screw 13.

[0058] The reset mechanism includes a baffle 22 fixedly mounted on the support rod 21, and a plurality of arc springs 23 are fixedly mounted between the baffle 22 and the receiving plate 19. When the screw 13 is transported to the side of the mounting frame 8 away from the vibration disk 3, the receiving plate 19 is transformed into a vertical clamping mode, and the screw 13 is locked by the clamping force alone, and the clamping force is not enough to clamp the screw 13, so the screw 13 will fall from between the two receiving plates 19. When the screw 13 falls from the vibration disk 3 onto the receiving plate 19, it will press against the receiving plate 19 to make the receiving plate 19 rotate around the support rod 21. Under the action of the arc spring 23, the receiving plate 19 will clamp the screw 13. Once the screw 13 is separated from the receiving plate 19, the receiving plate 19 will be reset under the action of the arc spring 23.

[0059] A limiting mechanism that matches the corresponding multiple material receiving plates 19 is installed on the mounting frame 8, and the limiting mechanism includes two support rods fixedly installed on the mounting frame 8. A limiting stop rod 33 that matches the material receiving plate 19 is fixedly installed on the two support rods. The end of the limiting stop rod 33 away from the vibration plate 3 is in an inverted trapezoidal shape.

[0060] As the receiving plate 19 rotates, the receiving plate 19 at the bottom will contact and abut against the limiting stop rod 33. Due to the special shape of the limiting stop rod 33, the receiving plate 19 will automatically rotate around the support rod 21. At this time, the distance between the two matching receiving plates 19 is greater than the maximum diameter of the screw 13, and the screw 13 will fall from between the two receiving plates 19, avoiding the situation where the screw 13 gets stuck in the receiving plate 19 and causes the chain 12 to get stuck.

[0061] Embodiment 4: The technical solution of this embodiment is different from that of Embodiment 3 in that, referring to Figure 4-Figure 9 , Fig.11 A detection component that cooperates with the screw 13 is installed on the material transmission bracket 6, and the detection component includes a detection bracket 11 fixedly installed on the material transmission bracket 6, a detection probe 24 is fixedly installed on the detection bracket 11, and a sensor controller 25 is fixedly installed on the detection probe 24. Two sets of unloading mechanisms that cooperate with corresponding material receiving plates 19 are installed on the detection bracket 11.

[0062] As the screws 13 on the receiving plate 19 move, the detection probe 24 will detect the appearance quality of the screws 13. Once there is a defect in the appearance quality, the detection probe 24 will send a signal to the sensor controller 25 to detect the screws 13 and ensure that the screws 13 put into use are all qualified products.

[0063] The unloading mechanism includes an electric push rod 14 fixedly mounted on the detection bracket 11 , the electric push rod 14 is electrically connected to the sensor controller 25 , and a push plate 20 matched with the material receiving plate 19 is fixedly mounted on the telescopic end of the electric push rod 14 .

[0064] When an unqualified screw 13 is detected, the sensor controller 25 will send a signal to the electric push rod 14 to retract the telescopic end of the electric push rod 14, and the electric push rod 14 will drive the push plate 20 to move toward the side close to the electric push rod 14. The movement of the push plate 20 will drive the corresponding receiving plate 19 to rotate around the support rod 21. The rotation of the receiving plate 19 will increase the distance between the two corresponding receiving plates 19, thereby losing the clamping of the screw 13, and the screw 13 will fall between the two receiving plates 19, so that the unqualified screw 13 is removed.

[0065] The specific operation steps of this device are as follows:

[0066] First, a batch of screws 13 are introduced into the vibration plate 3, and then the driving motor is turned on. The driving motor drives the vibration rocker arm 4 to rotate back and forth quickly, thereby driving the vibration sleeve to rotate. While the vibration sleeve rotates, it also moves back and forth up and down, thereby driving the vibration plate 3 to move back and forth up and down to produce a vibration effect. At the same time, the motor 7 drives the vibration plate 3 to rotate, thereby achieving the purpose of vibration arrangement of the vibration plate 3, so that the screws 13 in the vibration plate 3 rise along the inner wall of the vibration plate 3 to the discharge point of the vibration plate 3.

[0067] As the number of screws 13 at the discharge point increases, due to the short stroke at the discharge point, the screws 13 that reach the discharge point will immediately fall onto the material transfer bracket 6, and then fall onto the two material receiving plates 19 through the material transfer bracket 6. At this time, the motor 2 10 drives the driving end of the motor 2 10 to rotate, which drives the shaft to rotate. The rotation of the shaft drives the gear plate 17 to rotate, thereby driving the chain 12 to rotate. The rotation of the chain 12 will drive the mounting block 18 and the material receiving plate 19 to rotate, thereby realizing the transportation of the screws 13.

[0068] As the screw 13 on the receiving plate 19 moves, the detection probe 24 will detect the appearance quality of the screw 13. Once there is a defect in the appearance quality, the detection probe 24 will send a signal to the sensor controller 25, and the sensor controller 25 will send a signal to the electric push rod 14 to retract the telescopic end of the electric push rod 14. The electric push rod 14 will drive the push plate 20 to move to the side close to the electric push rod 14. The movement of the push plate 20 will drive the corresponding receiving plate 19 to rotate around the support rod 21. The rotation of the receiving plate 19 will increase the distance between the two corresponding receiving plates 19, thereby losing the clamping of the screw 13, and the screw 13 will fall between the two receiving plates 19, so that the unqualified screws 13 are removed.

[0069] As the receiving plate 19 rotates, the receiving plate 19 at the bottom will contact and resist the limiting stop rod 33. Due to the special shape of the limiting stop rod 33, the receiving plate 19 will automatically rotate around the support rod 21. At this time, the distance between the two matching receiving plates 19 is larger than the maximum diameter of the screw 13. The screw 13 will fall from between the two receiving plates 19 at the bottom and disengage from the device. A waste collection box can be set to collect and reprocess the rejected screws 13 to avoid the situation where the screw 13 gets stuck in the receiving plate 19 and causes the chain 12 to get stuck. Qualified screws 13 will continue to move with the receiving plate 19.

[0070] When the screw 13 is transported to the side of the mounting frame 8 away from the vibration plate 3, the receiving plate 19 is transformed into a vertical clamping mode, and the screw 13 is locked by the clamping force alone, but the clamping force is not enough to clamp the screw 13, so the screw 13 will fall from between the two receiving plates 19. At this time, the fallen screw 13 can be directly used on the screw machine.

[0071] Adjust the spacing between the two receiving plates 19 according to the size of the screw 13: manually rotate the gear cylinder 28, the rotation of the gear cylinder 28 will drive the tooth plate 15 and the tooth plate 26 to move in different directions, the tooth plate 15 and the tooth plate 26 will drive the corresponding mounting frame 8 to move in different directions, thereby driving the chain 12 and the receiving plate 19 to move, so as to change the spacing between the corresponding receiving plates 19 on the two chains 12, thereby achieving the purpose of clamping and transporting screws 13 of different sizes, and is suitable for screws 13 of different sizes.

[0072] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
