Description

Technical Field

[0001] This utility model belongs to the field of feeding equipment, and in particular relates to a roller-type feeding machine. Background Technology

[0002] During the product assembly process, bolts or screws are required. The current workpieces are often loaded using a vibratory feeder. However, the vibratory feeder has a complex structure and high cost. In addition, the vibratory feeder is limited by vertical space, resulting in a limited holding space and a small number of workpieces that can be held. Workers need to replenish the vibratory feeder at short intervals, which results in high labor costs and slow loading efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a roller-type feeder, which aims to solve the technical problem of low feeding efficiency in the prior art.

[0004] To achieve the above objectives, this utility model provides a roller-type feeder, comprising: a frame; a roller mounted on the frame and rotatable relative to the frame, the roller's axis extending in a front-rear direction, and an internal receiving cavity for holding a plurality of workpieces to be fed. Multiple claws are arranged circumferentially around the roller's axis within the receiving cavity, the claws being configured to rotate synchronously with the roller. The lower part of the receiving cavity is a picking position, and the upper part is a discharging position. When the roller rotates, a portion of the workpieces to be fed located at the picking position can roll into the claws located at the picking position and... As the pawl gradually moves upward, when the pawl moves from the material-taking position to the material-discharging position, the workpiece to be loaded, supported inside the pawl, slides down from the pawl. A loading track, installed on the frame, extends in the front-rear direction and gradually slopes downward from back to front. The rear end of the loading track extends into the material-bearing cavity, and the front end is located in front of the roller. The rear end of the loading track can receive the workpiece to be loaded sliding down from the pawl at the material-discharging position. A vibrator is used to generate vibration so that the workpiece to be loaded on the loading track can gradually move forward along the inclined direction of the loading track.

[0005] Optionally, it also includes a hopper, which is disposed in front of the roller and is used to hold a number of the workpieces to be loaded. The hopper is connected to the receiving cavity, and the internal space of the hopper is larger than the space of the receiving cavity.

[0006] Optionally, the hopper is an arc-shaped plate surrounding the bottom of the roller, and the hopper gradually tilts upward from back to front.

[0007] Optionally, guide plates are provided on both the left and right sides of the rear end of the feeding track. The two guide plates form flared inlets from bottom to top. The inlets are configured to receive the workpiece to be fed from the claw at the feeding position and guide the workpiece to be fed into the rear end of the feeding track. A vertically arranged end plate is also installed at the rear end of the feeding track. The end plate is connected to the feeding track, and both guide plates are installed on the end plate.

[0008] Optionally, at least one of the guide plates is adjustable in the left-right direction relative to the end plate.

[0009] Optionally, the claw is hook-shaped with a curved surface, and the curved surface is a minor arc surface.

[0010] Optionally, the frame is further provided with a driving gear and a driven gear, as well as a driving component for driving the driving gear to rotate. The driving gear and the driven gear mesh with each other, and the driven gear is coaxially arranged with the roller and rotates synchronously with the roller.

[0011] Optionally, the driven gear consists of a plurality of teeth surrounding the outer circumference of the roller, and the outer diameter of the driven gear is larger than the outer diameter of the driving gear.

[0012] Optionally, the rear end of the feeding track is a cantilever end and is not connected to the roller, and the feeding track can vibrate freely under the drive of the linear vibrator.

[0013] Optionally, the roller includes an annular body and a base plate. A plurality of claws are circumferentially arrayed on the inner surface of the annular body. The base plate is vertically arranged and blocks the annular body from the rear. The area with a front opening formed by the annular body and the base plate is the material receiving cavity. A boss is provided in the center of the base plate. A plurality of grooves are provided on the edge of the boss. The grooves fit into the partial edge contour of the claws. The plurality of claws are correspondingly embedded in the plurality of grooves.

[0014] Compared with the prior art, the above-mentioned one or more technical solutions of the roller-type feeder provided by this utility model embodiment have at least one of the following technical effects: During processing, several workpieces to be fed are first placed in the material receiving cavity of the roller, and then the feeder is started, so that the roller rotates around the axis extending in the front-back direction. During the rotation of the roller, the workpieces to be fed in the material receiving cavity can be supported and lifted upward by the claw in the material taking position. As the roller continues to rotate, the claw can rotate to the material releasing position in sequence. When the claw is in the material releasing position, the workpieces to be fed supported on the claw can slide down and finally fall into the rear end of the feeding track. Under the vibration of the direct vibrator, the workpieces to be fed on the feeding track can gradually move along the inclined feeding track, realizing the arrangement and feeding of several workpieces to be fed. Compared to traditional vibratory feeders, the roller-type feeder of this invention has a larger material-bearing space in the vertical direction, that is, the material-bearing cavity has a larger space in the vertical direction, which can increase the number of workpieces to be fed by the feeder, thereby reducing the number of times the workpieces to be fed are manually added to the feeder, and can significantly improve the sorting and feeding efficiency.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0034] like Figures 1 to 6 As shown, this utility model provides a roller-type feeder, including a frame 100, rollers 200, a feeding track 300, and a direct vibrator 400.

[0035] The roller 200 is mounted on the frame 100 and can rotate relative to the frame 100. The axis of the roller 200 extends in the front-to-back direction. The roller 200 has a receiving cavity 210 inside, which is used to hold several workpieces to be loaded. Multiple claws 221 are arranged in a circular array around the axis of the roller 200 inside the receiving cavity 210. The claws 221 are configured to rotate synchronously with the roller 200. The lower part of the receiving cavity 210 is the picking position 211, and the upper part is the discharging position. When the roller 200 rotates, some of the workpieces to be loaded located at the picking position 211 can roll into the claws 221 located at the picking position 211 and gradually move with the claws 221. When the claw 221 moves from the picking position 211 to the discharging position, the workpiece to be loaded supported in the claw 221 slides down from the claw 221. The loading track 300 is installed on the frame 100. The loading track 300 extends in the front-back direction and gradually slopes downward from back to front. The rear end of the loading track 300 extends into the receiving cavity 210. The front end of the loading track 300 is located in front of the roller 200. The rear end of the loading track 300 can receive the workpiece to be loaded sliding down from the claw 221 at the discharging position. The vibrator 400 is used to generate vibration so that the workpiece to be loaded on the loading track 300 can gradually move forward along the inclined direction of the loading track 300.

[0036] Understandably, during processing, several workpieces to be loaded are first placed in the receiving cavity 210 of the roller 200, and then the loading machine is started, causing the roller 200 to rotate around the axis extending in the front-back direction. During the rotation of the roller 200, the workpieces to be loaded in the receiving cavity 210 can be supported and lifted upward by the claw 221 at the picking position 211. As the roller 200 continues to rotate, the claw 221 can rotate to the discharging position 212 in sequence. When the claw 221 is at the discharging position 212, the workpieces to be loaded supported on the claw 221 can slide down and finally fall into the rear end of the loading track 300. Under the vibration of the vibrator 400, the workpieces to be loaded on the loading track 300 can gradually move along the inclined loading track 300, realizing the arrangement and loading of several workpieces to be loaded. Compared to traditional vibratory feeders, the roller-type feeder of this invention has a larger material-bearing space in the vertical direction, that is, the material-bearing cavity 210 has a larger space in the vertical direction, which can increase the number of workpieces to be fed by the feeder, thereby reducing the number of times the workpieces to be fed are manually added to the feeder, and significantly improving the sorting and feeding efficiency.

[0037] It should be noted that the feeding machine in this utility model is applicable to various types of workpieces, especially fasteners with similar shapes such as bolts and screws. Specifically, the feeding track 300 can be composed of two parallel support plates. When the bolt slides onto the feeding track 300, the bolt thread can extend between the two support plates, and the bolt nut can be secured on the two support plates.

[0038] Furthermore, when a workpiece to be loaded does not fall into the two parallel support plates of the loading track 300 in the above-described form, the vibration of the direct vibrator 400 provided in this utility model can cause the workpiece to be loaded on the loading track 300 to change into the above-described form, or cause it to fall back into the receiving cavity 210.

[0039] like Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment of this utility model, a hopper 500 is also included. The hopper 500 is disposed in front of the roller 200. The hopper 500 is used to hold a number of workpieces to be loaded. The hopper 500 is connected to the receiving cavity 210. The internal space of the hopper 500 is larger than the space of the receiving cavity 210. The hopper 500 can expand the space of the receiving cavity 210 to hold more workpieces to be loaded.

[0040] Furthermore, in one embodiment of this utility model, the hopper 500 is an arc-shaped plate surrounding the bottom of the roller 200. Preferably, the hopper 500 surrounds the lower half of the roller 200. In addition, the hopper 500 gradually tilts upward from back to front, and several workpieces to be loaded into the hopper 500 can gradually slide downward and backward and fill the bottom of the receiving cavity 210.

[0041] Reference Figure 4 In one embodiment of this utility model, guide plates 310 are provided on both the left and right sides of the rear end of the feeding track 300. The two guide plates 310 form flared inlets from bottom to top. The inlets are configured to receive the workpiece to be fed from the claw 221 of the feeding position and guide the workpiece to be fed into the rear end of the feeding track 300. A vertically arranged end plate 320 is also installed at the rear end of the feeding track 300. The end plate 320 can block the rear end face of the feeding track 300 to prevent the workpiece to be fed from sliding backward out of the feeding track 300. The end plate 320 is connected to the feeding track 300, and the two guide plates 310 are installed on the end plate 320.

[0042] In one embodiment of this utility model, at least one guide plate 310 is adjustable in the left-right direction relative to the end plate 320. When it is necessary to feed workpieces of different sizes, the left-right distance between the two support plates of the feeding track 300 can be adjusted to adapt to the current workpiece size. At the same time, the position and size of the feed port can be adjusted synchronously by adjusting the distance between the two guide plates 310, so that the feeding machine in this utility model can be used for workpieces of different sizes.

[0043] like Figure 3 , Figure 4 and Figure 6 As shown, in one embodiment of this utility model, the claw 221 is a hook-shaped surface with a curved surface. The curved surface is a minor arc surface, that is, the angle between the center of the curved surface and the line connecting the two ends of the curved surface is less than 180°. When the curvature of the curved surface is too small, the number of workpieces that the claw 221 can support will be reduced, which will reduce the feeding efficiency. When the curvature of the curved surface is too large, the workpiece is not easy to slip off the claw 221 at the feeding position 212, which also affects the feeding efficiency.

[0044] Reference Figure 5 In one embodiment of this utility model, the frame 100 is further provided with a driving gear 600, a driven gear 240, and a driving member 700 for driving the driving gear 600 to rotate. The driving gear 600 and the driven gear 240 mesh with each other, and the driven gear 240 is coaxially arranged with the roller 200 and rotates synchronously with the roller 200. The driving member 700 can be a motor. The driving gear 600 can directly mesh with the driven gear 240 for transmission, or it can indirectly mesh with the driven gear 240 for transmission by adding other gears.

[0045] Reference Figure 5 In one embodiment of the present invention, the driven gear 240 is composed of a plurality of teeth surrounding the outer circumference of the roller 200. The outer diameter of the driven gear 240 is larger than the outer diameter of the driving gear 600 to reduce the rotational speed of the driven gear 240, thereby reducing the rotational speed of the roller 200.

[0046] like Figure 2 As shown, in one embodiment of the present invention, the rear end of the feeding track 300 is a cantilever end and is not connected to the roller 200. The rear end of the feeding track 300, which is not connected to other structures, can vibrate freely under the drive of the straight vibrator 400, so that the vibration of the straight vibrator 400 will not affect other components except the feeding track 300.

[0047] like Figure 6 As shown, in one embodiment of this utility model, the roller 200 includes an annular body 220 and a base plate 230. Multiple claws 221 are arranged circumferentially on the inner surface of the annular body 220. The base plate 230 is vertically arranged and blocks the annular body 220 from the rear. The area with a front opening formed by the annular body 220 and the base plate 230 is a material receiving cavity 210. A boss 231 protrudes forward from the center of the base plate 230. Multiple grooves 2311 are provided on the edge of the boss 231. The grooves 2311 fit into the partial edge contours of the claws 221, and the multiple claws 221 are correspondingly embedded in the multiple grooves 2311. When the roller 200 rotates around its central axis, the rotational force is transmitted from the center of the roller 200 to the periphery, thereby causing the roller 200 to rotate as a whole. Specifically, the boss 231 in the middle of the roller 200 can increase the wall thickness of the middle part of the roller 200, making the transmission of rotational force more reliable and the bottom 230 less prone to deformation. In addition, by setting the groove 2311 to cooperate with the pawl 221, some of the rotational force can be transmitted through the contact surface at the position where the groove 2311 and the pawl 221 cooperate, which can further increase the stability of the roller 200 when rotating.

[0048] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0049] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
