Description

Technical Field

[0001] This invention relates to a feeding mechanism and a bar stock feeding device, belonging to the field of feeding tooling technology. Background Technology

[0002] In the manufacturing processes of many industries, shafts are used for connection. Shafts are also made of bar stock. If the bar stock is not sorted and arranged before shipment, it cannot be used directly in production. Therefore, it is necessary to arrange the bar stock on trays. These materials are small in volume, cylindrical in shape, difficult to arrange manually, and time-consuming.

[0003] In related technologies, material is distributed using a feeding fixture, which includes a hopper with a discharge port and a tray with several grooves. The hopper moves along the tray, and when the discharge port aligns with a groove, the bar stock falls into the groove. This feeding fixture has a simple structure and low cost. However, because the bar stock slides freely to the discharge port, jamming can easily occur near the discharge port. Summary of the Invention

[0004] The purpose of this invention is to provide a feeding mechanism and a bar stock feeding device to solve the problem of material jamming during the unloading process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A feeding mechanism is used to load a pile of bar stock into a loading component. The loading component includes a support surface and a plurality of material troughs recessed inward from the support surface. The plurality of material troughs are equally spaced, and a plurality of bar stock are correspondingly housed in the plurality of material troughs. The feeding mechanism includes:

[0007] A hopper having a storage chamber and a discharge port, the discharge port communicating with the storage chamber; and

[0008] A feeding assembly includes a feeding member rotatably connected to the hopper. The feeding member has a feeding portion and a protrusion. During the movement of the hopper along the material-carrying component under external force, the protrusion has a first state and a second state. In the first state, the protrusion abuts against the support surface of the material-carrying component, so that the feeding portion extends into the storage cavity and agitates the stacked bar stock, and the bar stock located at the discharge port also abuts against the support surface. In the second state, the protrusion extends into the trough, so that the feeding portion extends out of the storage cavity, and the bar stock falls from the discharge port into the trough.

[0009] As a further improvement of the present invention, the feeding assembly includes a first shaft, the hopper has a first mounting groove for receiving the feeding component, the first mounting groove is connected to the storage cavity, the first shaft is connected to the hopper, and the feeding component is rotatably connected to the first shaft.

[0010] As a further improvement of the present invention, along the length direction of the hopper, there is a first distance between the protrusion and the discharge port, and a second distance between two adjacent material troughs, wherein the first distance and the second distance are equal.

[0011] As a further improved technical solution of the present invention, the hopper includes a first inclined surface and a first bottom surface. The first inclined surface is the outer surface of the storage cavity. The first mounting groove passes through the first inclined surface. The feeding part includes a second inclined surface and a second bottom surface. The second inclined surface faces the storage cavity. The second bottom surface and the first bottom surface both face the support surface of the material-carrying component. The included angle between the second inclined surface and the second bottom surface is not greater than the included angle between the first inclined surface and the first bottom surface.

[0012] As a further improvement of the present invention, the feeding assembly further includes an elastic element, and the hopper is provided with a groove for receiving the elastic element, and the two ends of the elastic element respectively abut against the bottom of the groove and the feeding element.

[0013] As a further improvement of the present invention, the feeding assembly further includes a second shaft connected to the hopper. A notch is formed between the feeding part and the protrusion to accommodate the second shaft, so that the feeding component can rotate relative to the second shaft.

[0014] As a further improvement of the present invention, the feeding mechanism further includes a baffle assembly, which includes a baffle plate rotatably connected to the hopper.

[0015] During the process of dispensing the bar stock into the hopper, an external force drives the baffle plate to rotate away from the hopper to open the discharge port and keep it in a normally open state. During the process of transferring the hopper, an external force drives the baffle plate to rotate closer to the hopper to block the discharge port and keep it in a normally closed state.

[0016] As a further improvement of the present invention, the material blocking assembly includes a first shaft connected to the hopper, and the material blocking plate is rotatably connected to the first shaft.

[0017] The baffle plate includes a baffle portion and a bent portion, the bent portion being connected to the baffle portion. The baffle assembly further includes a first magnetic element and a second magnetic element, the first magnetic element being connected to the bent portion. The hopper includes a first inclined platform and a second inclined platform opposite to the first inclined platform. The first inclined platform includes a first inclined surface and a first bottom surface. At least the first inclined platform is a metal element capable of being attracted by the first magnetic element. The second magnetic element is disposed on the first bottom surface. At least the baffle portion is a metal element capable of being attracted by the second magnetic element.

[0018] During the process of dispensing the bar stock in the hopper, an external force drives the baffle to separate from the second magnetic component to loosen the discharge port, so that the first magnetic component is attracted to and connected to the first inclined platform and remains in a normally open state. During the transfer of the hopper, an external force drives the baffle to attract and connect to the second magnetic component to block the discharge port and remain in a normally closed state.

[0019] To achieve the above objectives, the present invention also adopts the following technical solution:

[0020] A bar stock feeding device includes a feeding mechanism and a material carrying component.

[0021] As a further improvement of the present invention, the material-carrying component is provided with an end ramp, the feeding mechanism includes a baffle assembly, the baffle assembly includes a baffle plate and a second magnetic component, the baffle plate includes a baffle portion, the baffle portion is in an inclined state after being separated from the second magnetic component, the material-carrying component is provided with a slot for accommodating the baffle portion, the baffle portion is in a horizontal state after being attracted and connected to the second magnetic component, and the inclined surface of the end ramp abuts against the baffle portion, so that the baffle portion is adjusted from an inclined state to a horizontal state.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] The automatic sorting of bar stock is achieved through the feeding mechanism, so that the stacked bar stock can fall into the material trough of the loading component one by one, thereby improving work efficiency.

[0024] By setting up a feeding component, when the protrusion abuts against the support surface of the material-carrying component during the movement of the hopper along the material-carrying component, the feeding component rotates upward around the hopper at a certain angle, so that the feeding part extends into the storage cavity and agitates the stacked bar stock, rearranging the bar stock and preventing it from getting stuck at the discharge port; when the protrusion extends into the trough, the feeding component rotates downward around the hopper at a certain angle, so that the feeding part extends out of the storage cavity. At this time, the discharge port is exactly opposite to another trough, and the bar stock falls from the discharge port into the trough, completing the unloading. Attached Figure Description

In this invention, the term "several" means two or more.

[0043] Please refer to Figures 1 to 15 As shown, the present invention discloses a bar stock feeding device, including a feeding mechanism and a loading component 40. The feeding mechanism is used to load a pile of bar stock into the loading component 40. The loading component 40 includes a support surface 401 and a plurality of material grooves 402 recessed inward from the support surface 401. The plurality of material grooves 402 are arranged at equal intervals, and a plurality of bar stocks are correspondingly stored in the plurality of material grooves 402.

[0044] See Figure 1 The feeding mechanism includes a hopper 1 and a feeding assembly 2 connected to the hopper 1. The hopper 1 has a storage chamber 101 for storing stacked bar stock. See also... Figure 3 The hopper 1 also has a discharge port 10a, which is connected to the storage chamber 101. The bar stock in the storage chamber 101 is discharged through the discharge port 10a. (See also...) Figure 2The discharge port 10a is located at the lower end of the hopper 1, and the upper end of the hopper 1 is provided with a feed port 10b. The bar stock is placed into the storage chamber 101 through the feed port 10b. Since the bar stock slides freely to the discharge port 10a, it is easy for the bar stock to get stuck at the discharge port 10ac. The material feeding component 2 is used to push the stuck bar stock, so that the bar stock can be discharged again and the bar stock can be discharged smoothly.

[0045] See Figure 2 The hopper 1 includes a first inclined platform 11, a second inclined platform 12 opposite to the first inclined platform 11, a first side plate 13 connecting one end of the first inclined platform 11 and one end of the second inclined platform 12, and a second side plate 14 connecting the other end of the first inclined platform 11 and the other end of the second inclined platform 12. The first inclined platform 11 and the second inclined platform 12 are spaced apart, that is, there is a gap between the end of the first inclined platform 11 near the material-carrying component 40 and the end of the second inclined platform 12 near the material-carrying component 40 to form a discharge port 10a.

[0046] In some implementations, see Figure 2 and Figure 3 The first side plate 13 is connected to one end of the first inclined platform 11 and one end of the second inclined platform 12 by the first screw 151, and the second side plate 14 is connected to the other end of the first inclined platform 11 and the other end of the second inclined platform 12 by the second screw 152, thereby realizing the detachable connection between the first inclined platform 11, the second inclined platform 12, the first side plate 13 and the second side plate 14.

[0047] See Figure 5 The first inclined platform 11 is positioned and connected to the first side plate 13 and the second side plate 14 through the first connecting shaft 16, and the second inclined platform 12 is positioned and connected to the first side plate 13 and the second side plate 14 through the second connecting shaft 17. The first connecting shaft 16 and the second connecting shaft 17 make the structure of the silo 1 more stable.

[0048] In the embodiments illustrated in the present invention, see... Figure 5 and Figure 6 The first side plate 13 is provided with two first slots 131, and the second side plate 14 is provided with two second slots 141. The two ends of the first inclined platform 11 are respectively inserted into one of the first slots 131 and one of the second slots 141, and the two ends of the second inclined platform 12 are respectively inserted into the other first slot 131 and the other second slot 141.

[0049] See Figure 8The first inclined platform 11 includes a first inclined surface 112 and a first bottom surface 113, and the second inclined platform 12 includes a third inclined surface 121. Both the first inclined surface 112 and the third inclined surface 121 are outer surfaces of the storage cavity 101. By setting the first inclined surface 112 and the third inclined surface 121, the bar stock can automatically slide downwards. In this invention, the first inclined surface 112 and the third inclined surface 121 can be inclined planes or inclined arc surfaces, as long as the bar stock can roll down along the inclined surface.

[0050] See Figure 4 The hopper 1 includes a protruding edge 130, which extends downward from the first side plate 13 and / or the second side plate 14 and protrudes beyond the first inclined platform 11 and the second inclined platform 12. See also Figure 7 The material-carrying component 40 is provided with a chute 404, and the protruding edge 130 cooperates with the chute 404 to make the hopper 1 move along the chute 404.

[0051] See Figure 5 The feeding assembly 2 includes a feeding element 21 and a first shaft 22. The hopper 1 has a first mounting groove 111 for receiving the feeding element 21. The first mounting groove 111 communicates with the storage cavity 101 and extends through the first inclined surface 112 of the first ramp 11. The first shaft 22 is connected to the hopper 1, and the feeding element 21 is rotatably connected to the first shaft 22. Specifically, the first mounting groove 111 is recessed inward from the first bottom surface 113 of the first ramp 11.

[0052] See Figure 5 and Figure 11 The feeding component 21 is provided with a feeding part 212 and a protrusion 213. During the movement of the hopper 1 along the loading component 40 under the action of external force, the protrusion 213 has a first state and a second state, such as... Figure 11 As shown, in the first state, the protrusion 213 abuts against the support surface 401 of the material-carrying component 40, so that the feeding part 212 extends into the storage cavity 101 and agitates the stacked bar stock, and the bar stock located at the discharge port 10a also abuts against the support surface 401; as Figure 8 As shown, in the second state, the protrusion 213 extends into the material trough 402, so that the feeding part 212 extends out of the storage cavity 101, and the bar stock falls from the discharge port 10a into the material trough 402. That is, the protrusion 213 can both enter the material trough 402 and abut against the support surface 401 between adjacent material troughs 402.

[0053] In some implementations, see Figure 15The material feeding component 21 includes a main body 211, a material feeding part 212 connected to the main body 211, and a protrusion 213 connected to the main body 211. The main body 211, the material feeding part 212, and the protrusion 213 are integrally formed. The main body 211 is provided with a first through hole 2111, and a first shaft 22 passes through the first through hole 2111 of the main body 211. In addition, the first shaft 22 passes through the first inclined platform 11, and both ends of the first shaft 22 are fixedly connected to the first side plate 13 and the second side plate 14, respectively.

[0054] See Figure 8 Along the length L of the hopper 1, there is a first distance A1 between the protrusion 213 and the discharge port 10a, and a second distance A2 between two adjacent troughs 402. The first distance A1 and the second distance A2 are equal. This arrangement ensures that when the protrusion 213 extends into the trough 402 of the first station, the discharge port 10a is exactly opposite to the trough 402 adjacent to the first station.

[0055] In some implementations, see Figure 15 The feeding part 212 includes a second inclined surface 2121 and a second bottom surface 2122. The second inclined surface 2121 faces the storage cavity 101, and the second bottom surface 2122 and the first bottom surface 113 of the first inclined platform 11 both face the support surface 401 of the material carrying component 40. The included angle between the second inclined surface 2121 and the second bottom surface 2122 is not greater than the included angle between the first inclined surface 112 and the first bottom surface 113. In this way, the feeding part 212 can be inserted into the storage cavity 101 when the feeding component 21 rotates at a small angle, which is easy to adjust.

[0056] See Figure 8 The feeding assembly 2 also includes an elastic element 23. The hopper 1 has a groove 114 for receiving the elastic element 23. The two ends of the elastic element 23 abut against the bottom of the groove 114 and the body 211 of the feeding component 21, respectively. During the process of the protrusion 213 moving from the trough 402 to the support surface 401, the feeding component 21 compresses the elastic element 23. When the protrusion 213 moves from the support surface 401 to the trough 402, the elastic element 23 rebounds, causing the feeding component 21 to reset. At the same time, the elastic element 23 applies a spring force to the feeding component 21, so that the feeding component 21 can better maintain its reset state. The reset state of the feeding component 21 is also the feeding state of the hopper 1. Specifically, the elastic element 23 is a spring, and the groove 114 is formed by recessing inward from the bottom of the first mounting groove 111.

[0057] See Figure 11The feeding assembly 2 also includes a second shaft 24, which is connected to the hopper 1. A notch 210 is formed between the feeding part 212 and the protrusion 213. The second shaft 24 is housed through the notch 210 so that the feeding part 21 can rotate relative to the second shaft 24. The second shaft 24 limits the feeding part 21 to prevent it from rotating downwards excessively and to avoid the feeding part 21 from colliding with the material carrier 40.

[0058] See Figure 2 The feeding mechanism also includes a baffle assembly 3, which is used to block the discharge port 10a when transferring the material hopper 1. See also Figure 4 The baffle assembly 3 includes a baffle plate 31, which is rotatably connected to the hopper 1. During the process of dispensing the bar stock in the hopper 1, an external force drives the baffle plate 31 to rotate away from the hopper 1 to loosen the discharge port 10a and keep it in a normally open state. During the process of transferring the hopper 1, an external force drives the baffle plate 31 to rotate closer to the hopper 1 to block the discharge port 10a and keep it in a normally closed state.

[0059] Specifically, the baffle assembly 3 includes a first shaft 22 connected to the hopper 1, and a baffle plate 31 rotatably connected to the first shaft 22. The hopper 1 has a second mounting groove 115, and the baffle plate 31 is at least partially located in the second mounting groove 115. The first shaft 22 passes through the baffle plate 31 at the second mounting groove 115. That is, the baffle plate 31 and the feeder 21 share the first shaft 22, reducing the number of parts.

[0060] See Figure 5 The baffle plate 31 includes a baffle portion 311 and a bending portion 312, with the bending portion 312 connected to the baffle portion 311. The baffle assembly 3 also includes a first magnetic element 32 and a second magnetic element 33. The first magnetic element 32 is connected to the bending portion 312, and at least the first inclined platform 11 is a metal element that can be attracted by the first magnetic element 32. The second magnetic element 33 is disposed on the first bottom surface 113, and at least the baffle portion 311 is a metal element that can be attracted by the second magnetic element 33. During the dispensing of bar stock in the hopper 1, an external force drives the baffle portion 311 to separate from the second magnetic element 33 to loosen the discharge port 10a, allowing the first magnetic element 32 to be attracted and connected to the first inclined platform 11 and remain in a normally open state. During the transfer of the hopper 1, an external force drives the baffle portion 311 to be attracted and connected to the second magnetic element 33 to block the discharge port 10a and remain in a normally closed state. The external force can be a force applied manually.

[0061] Since the material loading component 40 is provided with multiple material troughs 402, each material trough 402 includes several material troughs 402. When the material hopper 1 needs to be transferred to another material trough 402 after the material is finished being loaded in one material trough 402, the material blocking part 311 blocks the discharge port 10a to prevent the bar material from falling out.

[0062] In the embodiment illustrated in the present invention, the first inclined platform 11, the second inclined platform 12, the first side plate 13, and the second side plate 14 are all metal parts. Of course, in other embodiments, only the first inclined platform 11 may be a metal part.

[0063] See Figure 7 After the material blocking part 311 is separated from the second magnetic component 33, it is in an inclined state. Correspondingly, the material carrying component 40 is provided with a slot 405 for accommodating the material blocking part 311, so that the material blocking part 311 in the inclined state can move smoothly on the material carrying component 40, and the material blocking part 311 does not contact the material carrying component 40, thereby reducing the moving resistance of the material blocking part 311.

[0064] The slot 405 divides the material trough 402 into two parts. Correspondingly, two material feeding components 21 are also provided. The two material feeding components 21 cooperate with the two parts of the material trough 402. The material bin 1 is provided with two first mounting slots 111, and the two material feeding components 21 are correspondingly located in the two first mounting slots 111. The baffle plate 31 is located between the two material feeding components 21.

[0065] See Figure 9 Along the height direction H of the hopper 1, the first magnetic element 32 is located above the second magnetic element 33. By lifting the bending part 312 upward, the material blocking part 311 can be separated from the second magnetic element 33, and the first magnetic element 32 can be attracted and connected to the first inclined platform 11, thereby enabling the material blocking part 311 to be in an inclined state; by pressing the bending part 312 downward, the material blocking part 311 and the second magnetic element 33 can be connected. By positioning the first magnetic element 32 above the second magnetic element 33, the automatic closing of the baffle plate 31 or the sealing of the discharge port 10a can be better achieved.

[0066] For details, see Figure 9 The bending portion 312 includes a vertical portion 3121 and a horizontal portion 3122, with the vertical portion 3121 connecting the baffle portion 311 and the horizontal portion 3122. The baffle plate 31 has a second through hole 3120, through which the first shaft 22 passes. The second through hole 3120 is located at one end of the vertical portion 3121 near the horizontal portion 3122.

[0067] See Figure 13 The horizontal portion 3122 is provided with a first fixing groove 31221, and the first magnetic element 32 is installed in the first fixing groove 31221. The hopper 1 is provided with a second fixing groove 116, which is recessed inward from the first bottom surface 113, and the second magnetic element 33 is installed in the second fixing groove 116. In some embodiments, two second magnetic elements 33 are provided, and the two second magnetic elements 33 are spaced apart.

[0068] In some embodiments, the baffle plate 31 is a single piece, and the baffle member 31 is a metal part. Of course, in other embodiments, the baffle part 311 and the bending part 312 are separately provided, and only the baffle part 311 is a metal part.

[0069] See Figure 1 and Figure 9 Both ends of the material-carrying component 40 are provided with end ramps 403. After the material-blocking part 311 is separated from the second magnetic component 33, it is in an inclined state. After the material-blocking part 311 is attracted and connected to the second magnetic component 33, it is in a horizontal state. The inclined surface 4031 of the end ramp 403 abuts against the material-blocking part 311, so that the material-blocking part 311 is adjusted from the inclined state to the horizontal state.

[0070] The working process of the bar stock feeding device of the present invention is as follows: The operator pushes the hopper 1 to move along the loading component 40. When the protrusion 213 extends into the trough 402, the feeding component 21 rotates downward around the first axis 22 at a certain angle, so that the feeding part 212 extends out of the storage cavity 101. At this time, the discharge port 10a is exactly opposite to another trough 402, and the bar stock falls from the discharge port 10a into the trough 402. When the protrusion 213 abuts against the support surface 401 of the loading component 40, the feeding component 21 rotates upward around the first axis 22 at a certain angle, so that the feeding part 212 extends into the storage cavity 101 and moves the stacked bar stock, rearranging the bar stock to prevent the bar stock from getting stuck at the discharge port 10a. At this time, the bar at the discharge port 10a also abuts against the support surface 401, preventing the bar from falling out. After all the material in this row of troughs 402 is assembled, the inclined surface 4031 of the end ramp 403 abuts against the baffle part 311, adjusting the baffle part 311 from the inclined state to the horizontal state. At this time, when the baffle part 311 is attracted and connected to the second magnetic component 33, the operator manually moves the other row of troughs 402 of the hopper 1. Then, the operator lifts the bending part 312 upward to separate the baffle part 311 from the second magnetic component 33, so that the first magnetic component 32 is attracted and connected to the first ramp 11, thereby enabling the baffle part 311 to be in an inclined state and opening the discharge port 10a.
