Description

Technical Field

[0001] The invention belongs to the technical field of feeder equipment, in particular to a feeder device for fastener production. Background Art

[0002] Fasteners are a type of mechanical parts used for fastening connections and are extremely widely used. They usually include bolts, studs, screws, nuts and other types. In the production process of fasteners, loading devices are often required to transport the fasteners. The loading device can automatically transport the fasteners from one process to the next for subsequent assembly, weighing and other processes.

[0003] The invention patent with announcement number CN114955369B discloses an automatic feeding device for heat-resistant fasteners, including a cylinder, a discharge body is installed on the right side of the cylinder, the cylinder and the discharge body can rotate slowly, a discharge port is opened inside the discharge body, the cavity of the cylinder is connected to the discharge port, and an air film is fixedly installed on the wall of the discharge body. The invention arranges the cylinder and the deflection member, utilizes the cylinder that rotates slowly and tilts, and then causes the fasteners sliding down in the cylinder to be driven and diverted by the cylinder, so that under unit conditions, the amount of material sliding down is reduced, and the discharge port is not easy to be blocked by backlog. At the same time, the rotating cylinder will drive the deflection member to rotate, so that the deflection member forms a convex structure in the cylinder, and through this structure, a certain degree of obstruction is generated on the material sliding down in the cylinder, so that the sliding speed of the material is slowed down, thereby reducing the probability of backlog and blockage at the discharge port due to the fast sliding speed of the material.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] The fasteners are loaded by placing them into a cylinder and then using a discharge port to drop them onto a conveyor belt. However, when the fasteners are nuts, after the nuts fall onto the conveyor belt, they will roll and may roll from the edge of the conveyor belt to the ground, affecting the loading process. In addition, the nuts that fall onto the conveyor belt may be in a stacked or upright state, and the stacked nuts need to be separated one by one during subsequent assembly, which increases the complexity and time of pre-assembly preparations and reduces assembly efficiency. The upright nuts may require additional work to lay them flat during assembly, which increases the complexity and time of assembly. For example, when the nuts need to be visually inspected before assembly, the stacked and upright nuts will affect the normal visual inspection, and the above situation will occur.

[0006] To this end, the present invention provides a feeding device for fastener production. Summary of the invention

[0045] Specifically, fasteners are a type of mechanical parts used for fastening and connection and are extremely widely used. They usually include bolts, studs, screws, nuts and other types. In the production process of fasteners, a feeding device is often required to transport the fasteners. The feeding device can automatically transport the fasteners from one process to the next process for subsequent assembly, weighing and other processes. When the existing fastener feeding device is used, the fasteners are placed in the barrel and then the fasteners are dropped onto the conveyor belt through the discharge port 8 to achieve the feeding of the fasteners. However, when the fasteners are nuts, the nuts fall to the conveyor belt. After being put on the conveyor belt, the nuts may roll and then roll down from the edge of the conveyor belt to the ground, affecting the loading process. In addition, the nuts that fall onto the conveyor belt may be in a stacked or upright state, and the stacked nuts need to be separated one by one during the subsequent assembly, which increases the complexity and time of the pre-assembly preparation work and reduces the assembly efficiency. The upright nuts may require additional work to lay them flat during assembly, which increases the complexity and time of assembly. For example, when the nuts need to be visually inspected before assembly, the stacked and upright nuts will affect the normal visual inspection, and the above situation will occur.

[0046] Therefore, in order to solve the above problems, when the present embodiment is in use, the base 1 is placed on one side of the conveyor belt, and the two side edges of the base 1 are kept parallel to the conveyor belt, and the direction from baffle 1 6 to baffle 2 9 is the conveying direction of the conveyor belt, and then the electric push rod 10 is started to drive the lifting plate 3 to descend, so that the slide rod 5 slides downward, and the baffle 1 6 can be lowered, so that the lower end surface of the baffle 1 6 is in a state of being about to contact with the upper surface of the conveyor belt, and the gap between the lower end surfaces of the baffle 1 6 and the baffle 3 16 and the upper surface of the conveyor belt is less than the thickness of the nut, and then the motor 17 is started to drive the threaded rod 4 45 to rotate, so that the connecting rod 7 and the baffle 2 9 are lowered at the same time, so that the distance between the lower end surface of the baffle 2 9 and the upper surface of the conveyor belt is greater than the thickness of the nut and less than the height of the nut standing up, and then according to the width of the conveyor belt, the electric push rod 20 is started to drive the lifting block 19 to rise. The baffle plate 3 16 is lowered, and the baffle plate 3 16 is slid on the baffle plate 2 9 under the action of the connecting rod 18, so that the baffle plates 3 16 on both sides are close to or away from each other, and the spacing of the baffle plates 3 16 is adjusted so that the spacing of the two baffle plates 3 16 is smaller than the width of the conveyor belt. While adjusting the spacing of the two baffle plates 3 16, the motor 6 43 is started to drive the threaded rods 3 44 on both sides to rotate, so that the push rod 2 35 extends from the inner cavity of the push rod 1 34, so that the end surfaces of the two push rods 2 35 that are away from each other are flush with the end surfaces of the two T-shaped rods 15 that are close to each other, and the threaded rod 2 39 is driven to rotate by starting the motor 5 38, so that the limit rod 40 slides up and down, and the height of the T-shaped rod 15 is adjusted so that the lower surface of the T-shaped rod 15 is flush with the lower surfaces of the push rod 1 34 and the push rod 2 35, and when the push rod 1 34, the push rod 2 35, and the T-shaped rod 15 are translated, they can touch the erected nut;

[0047] Then the nuts are added through the feed barrel 4, and fall to the upper surface of the conveyor belt after passing through the discharge port 8. The baffle 1 6 and the baffle 3 16 can be used to block the nuts that fall to the upper surface of the conveyor belt to prevent the nuts from rolling down from the edge of the conveyor belt. In addition, under the action of the conveyor belt, the nuts begin to move. When the nuts are stacked or upright, the nuts will not pass through the bottom of the baffle 2 9, while the nuts that are not stacked and laid flat can pass through the bottom of the baffle 2 9. In addition, the upright nuts may cling to the front end surface of the baffle 2 9 and cannot continue to move. Therefore, the nuts can be By starting the motor 3 28, the crank 29 rotates, and when the displacement block 46 makes a circular motion, the displacement block 46 slides inside the slide plate 1 30, so that the slide plate 1 30 moves back and forth, and the L-shaped plate 33 slides back and forth on the slide rod 5 31, so that the push rod 1 34 and the push rod 2 35 can pass through the groove 27, and the nut that is in contact with the front end surface of the baffle plate 2 9 can be pushed to tilt and lay flat, and then it can pass through the bottom of the baffle plate 2 9 and continue to be transported, thereby avoiding the situation where the nut is in contact with the front end surface of the baffle plate 2 9, resulting in the nut being unable to move normally with the conveyor belt;

[0048] The polygonal face of the nut is regarded as the front face, and the rest are the side faces. When the nut is erected and the front face contacts the baffle plate 29, the push rod 1 34 and the push rod 2 35 can easily push the nut down. However, when the side face of the nut contacts the baffle plate 29 and the thickness of the nut is large, the nut will slide on the surface of the conveyor belt instead of tipping over. Therefore, after the push rod 1 34 and the push rod 2 35 complete a push-down action and reset, and before the next push-down action is performed, the electric push rod 3 23 is started and drives the paddle plate 25 to descend, so that the slide rod 4 24 slides on the upper end of the L-shaped rod 22, so that the paddle plate 25 is lowered. The lever 25 is lowered, and the lower end surface of the lever plate 25 is flush with the lower end surfaces of the push rod 1 34 and the push rod 2 35, and the rear end surface of the lever plate 25 is fitted with the front end surface of the baffle plate 2 9. Then the motor 21 is started, and when the threaded rod 1 26 rotates, the L-shaped rod 22 moves horizontally on the slide rod 3 14 and the threaded rod 1 26, so that the lever plate 25 moves horizontally. When the lever plate 25 moves horizontally, it can contact the front of the nut that is not easily pushed down by the push rod 1 34 and the push rod 2 35, so that the nut is pushed again until the nut is tilted and laid flat, and the lateral movement distance of the lever plate 25 does not exceed the distance between the end surfaces of the two T-shaped rods 15 that are close to each other. , and the minimum spacing between the paddle 25 and the T-bar 15 is not less than the maximum width of the nut, so as to prevent the paddle 25 from being deformed due to being squeezed by the nut. When the paddle 25 realizes a push-down action, the paddle 25 is driven to rise. At this time, the push rod 1 34 and the push rod 2 35 extend from the groove 27 again, and the push-down action can be performed alternately without interfering with each other. When the side surface of the nut contacts the baffle 2 9 and is at the angle between the baffle 2 9 and the baffle 3 16, the front face of the nut abuts against the baffle 3 16, and the movement of the paddle 25 is not enough to push the nut at the angle. Therefore, when the dial plate 25 moves horizontally, the motor 437 starts and drives the slide plate 241 to rotate. The slide plate 241 drives the T-bar 15 to slide on the limit rod 40 by using the guide column 42. The T-bar 15 pushes the nut between the angle of the baffle plate 29 and the baffle plate 3 16, and the nut can be pushed down again, thereby further avoiding the dead angle of pushing down, so that the nut can be in a flat state; and, according to the above, the T-bar 15, the push rod 1 34, the push rod 2 35, and the dial plate 25 can only contact with the upright or stacked nuts, and will not touch the square nuts;

[0049] Therefore, by utilizing the push-down and lay-flat blocking mechanism, the rolling nut can be blocked when the nut falls onto the conveyor belt through the discharge port 8, so that the movement range of the nut is limited to prevent the nut from rolling down through the edge of the conveyor belt, and the upright or stacked nuts can be pushed down so that the nuts all pass through the bottom of the baffle 2 9 in a flat state, and the pushing down action is completed through mutual cooperation in multiple directions, which effectively avoids pushing down dead corners and improves the pushing down effect, thereby avoiding the need for the stacked nuts to be separated one by one during subsequent assembly, which increases the complexity and time of the pre-assembly preparation work, improves the assembly efficiency, and avoids the need for extra work to lay the upright nuts flat during assembly, thereby reducing the complexity and time of assembly.

[0050] In this embodiment, Figure 2 As shown, an electromagnetic vibrator 11 is provided at one end of the upper side of the feed barrel 4;

[0051] Specifically, when nuts are added through the feed barrel 4, the electromagnetic vibrator 11 can be started, and with the cooperation of the spring damper 12, the feed barrel 4 can be vibrated to intensify the falling of the nuts, thereby avoiding the situation where the nuts are blocked at the discharge port 8 and affecting the feeding effect.

[0052] Working principle: place the base 1 on one side of the conveyor belt, and keep the two side edges of the base 1 parallel to the conveyor belt, and the direction from baffle 1 6 to baffle 2 9 is the conveying direction of the conveyor belt, then start the electric push rod 10 to drive the lifting plate 3 to descend, so that the slide rod 5 slides downward, and the baffle 6 can be lowered, so that the lower end surface of the baffle 1 6 is about to contact the upper surface of the conveyor belt, and the gap between the lower end surface of the baffle 1 6 and the upper surface of the conveyor belt is less than the thickness of the nut, then start the motor 17 to drive the threaded rod 4 45 to rotate, so that the connecting rod 7 and baffle 2 9 descend at the same time, so that the distance between the lower end surface of the baffle 2 9 and the upper surface of the conveyor belt is greater than the thickness of the nut, and less than the height of the nut standing up, and then start according to the width of the conveyor belt. The electric push rod 20 drives the lifting block 19 to rise and fall, and under the action of the connecting rod 18, the baffle plate 3 16 slides on the baffle plate 2 9, so that the baffle plates 3 16 on both sides are close to or away from each other, and the spacing of the baffle plates 3 16 is adjusted so that the spacing of the two baffle plates 3 16 is smaller than the width of the conveyor belt. While adjusting the spacing of the two baffle plates 3 16, the motor 6 43 is started to drive the threaded rods 3 44 on both sides to rotate, so that the push rod 2 35 extends from the inner cavity of the push rod 1 34, so that the end surfaces of the two push rods 2 35 that are away from each other are flush with the end surfaces of the two T-shaped rods 15 that are close to each other, and the threaded rod 2 39 is driven to rotate by the starting motor 5 38, so that the limit rod 40 slides up and down, and the height of the T-shaped rod 15 is adjusted so that the lower surface of the T-shaped rod 15 is aligned with the push rod 1 34, The lower surface of the push rod 2 35 is flush, and when the push rod 1 34, the push rod 2 35, and the T-bar 15 are translated, they can touch the erected nuts; then the nuts are added through the feed barrel 4, and fall to the upper surface of the conveyor belt after passing through the discharge port 8. During this period, the electromagnetic vibrator 11 can be started, and with the cooperation of the spring damper 12, the feed barrel 4 can be vibrated to intensify the falling of the nuts, so as to avoid the nuts being blocked at the discharge port 8 and affecting the feeding effect. The baffle 1 6 and the baffle 3 16 can be used to block the nuts that fall to the upper surface of the conveyor belt, so as to avoid the nuts rolling off the edge of the conveyor belt, and under the action of the conveyor belt, the nuts start to move. When the nuts are in a stacked or erected state, the nuts will not pass through the bottom of the baffle 2 9, and the nuts will not be stacked. The stacked and flat nuts can pass through the bottom of the baffle plate 29, and the erected nuts may be tightly attached to the front end surface of the baffle plate 29 and cannot continue to move. Therefore, the crank 29 can be rotated by starting the motor 3 28. When the displacement block 46 makes a circular motion, the displacement block 46 slides on the inner side of the slide plate 1 30, so that the slide plate 1 30 moves back and forth, and the L-shaped plate 33 slides back and forth on the slide rod 5 31, so that the push rod 1 34 and the push rod 2 35 can pass through the groove 27, and the nut that is in contact with the front end surface of the baffle plate 29 can be pushed to tilt and lay flat, so that it can pass through the bottom of the baffle plate 29 and continue to be transported, thereby avoiding the situation where the nut is in contact with the front end surface of the baffle plate 29, resulting in the nut being unable to move normally with the conveyor belt;The polygonal face of the nut is regarded as the front face, and the rest are the side faces. When the nut is erected and the front face contacts the baffle plate 29, the push rod 1 34 and the push rod 2 35 can easily push the nut down. However, when the side face of the nut contacts the baffle plate 29 and the thickness of the nut is large, the nut will slide on the surface of the conveyor belt instead of tipping over. Therefore, after the push rod 1 34 and the push rod 2 35 complete a push-down action and reset, and before the next push-down action is performed, the electric push rod 3 23 is started and drives the paddle plate 25 to descend, so that the slide rod 4 24 slides on the upper end of the L-shaped rod 22, so that the paddle plate 25 is lowered. The lever 25 is lowered, and the lower end surface of the lever plate 25 is flush with the lower end surfaces of the push rod 1 34 and the push rod 2 35, and the rear end surface of the lever plate 25 is fitted with the front end surface of the baffle plate 2 9. Then the motor 21 is started, and when the threaded rod 1 26 rotates, the L-shaped rod 22 moves horizontally on the slide rod 3 14 and the threaded rod 1 26, so that the lever plate 25 moves horizontally. When the lever plate 25 moves horizontally, it can contact the front of the nut that is not easily pushed down by the push rod 1 34 and the push rod 2 35, so that the nut is pushed again until the nut is tilted and laid flat, and the lateral movement distance of the lever plate 25 does not exceed the distance between the end surfaces of the two T-shaped rods 15 that are close to each other. , and the minimum spacing between the paddle 25 and the T-bar 15 is not less than the maximum width of the nut, so as to prevent the paddle 25 from being deformed due to being squeezed by the nut. When the paddle 25 realizes a push-down action, the paddle 25 is driven to rise. At this time, the push rod 1 34 and the push rod 2 35 extend from the groove 27 again, and the push-down action can be performed alternately without interfering with each other. When the side surface of the nut contacts the baffle 2 9 and is at the angle between the baffle 2 9 and the baffle 3 16, the front face of the nut abuts against the baffle 3 16, and the movement of the paddle 25 is not enough to push the nut at the angle. Therefore, when the dial plate 25 moves horizontally, the motor 437 starts and drives the slide plate 241 to rotate. The slide plate 241 drives the T-bar 15 to slide on the limit rod 40 by using the guide column 42. The T-bar 15 pushes the nut between the angle of the baffle plate 29 and the baffle plate 3 16, and the nut can be pushed down again, thereby further avoiding the dead angle of pushing down, so that the nut can be in a flat state; and, according to the above, the T-bar 15, the push rod 1 34, the push rod 2 35, and the dial plate 25 can only contact with the upright or stacked nuts, and will not touch the square nuts;Thus, by utilizing the push-down flat-laying blocking mechanism, when the nut falls onto the conveyor belt through the discharge port 8, the rolling nut can be blocked, so that the moving range of the nut is limited, and the nut is prevented from rolling down through the edge of the conveyor belt. In addition, the upright or stacked nuts can be pushed down, so that the nuts all pass through the bottom of the baffle plate 2 9 in a flat state. Moreover, the pushing down action is completed through the mutual cooperation of multiple directions, which effectively avoids the push-down dead angle and improves the push-down effect, thereby avoiding the stacked nuts from being separated one by one during subsequent assembly, which increases the complexity and time of the pre-assembly preparation work, improves the assembly efficiency, and avoids the need for extra work to lay the upright nuts flat during assembly, thereby reducing the complexity and time of assembly. ;
