Description

Technical Field

[0001] The utility model relates to the technical field of material feeding, in particular to an automatic directional feeding device for non-end cap screws with mounting holes at the ends. Background Art

[0002] Vibratory feeding, currently, usually refers to the process of using vibration equipment to transport materials from storage bins or containers to downstream equipment or processes. Vibratory feeding helps to improve the efficiency and uniformity of material transportation, and is common in various industrial production and processing fields. In industrial production, vibratory feeding is usually an important part of the automated production line, which can improve production efficiency, reduce labor costs, and ensure the stability and accuracy of material transportation. Through reasonable design and selection of appropriate vibration equipment, efficient material transportation and processing can be achieved, thereby improving the overall efficiency and quality of the production line.

[0003] During the vibration feeding process, it is usually required that the workpiece must be output in a predetermined posture after the vibration feeding, which is usually achieved by setting a sorting mechanism in the vibration feeder. There are two traditional sorting mechanisms: gravity sorting mechanism and height sorting mechanism. The gravity sorting mechanism is to set an adjustment structure on the track of the feeding channel to adjust the width of the track to a predetermined width. When the workpiece passes through the adjustment structure, the workpiece with a compliant posture passes, and the workpiece with an uncompliant posture falls on the track under the action of gravity to participate in vibration and sorting again. However, when this method encounters workpieces with similar width and height, identification becomes very difficult; the height sorting mechanism is to set an air sorting structure at a predetermined height on the side wall of the feeding channel, and blow air from the side wall to the outside of the track. When the workpiece passes through the air sorting structure, the workpiece with a compliant posture passes, and the workpiece with an uncompliant posture is blown off to participate in vibration and sorting again, or, by setting a height limit block at a predetermined height on the side wall, the workpiece with a compliant posture passes, and the workpiece with an uncompliant posture hits the height limit block and falls to participate in vibration and sorting again.

[0004] The traditional sorting mechanism has a low screening rate for incorrect postures of workpieces during vibration feeding, and the sorting efficiency is low, especially when the workpieces are cylindrical, octagonal, hollow cylindrical and hollow octagonal. For screws without end caps, due to their uniform overall thickness, it is very difficult to use traditional vibration feeding to screen.

[0005] For screws without end caps and with an inward mounting hole at one end of the screw, in order to facilitate subsequent installation of the screw, the screw needs to be loaded in a predetermined direction during the loading process. Obviously, the traditional loading method cannot meet this requirement.

[0006] Since vibration feeding produces a lot of noise, the efficiency of vibration feeding is also an important issue that needs to be addressed.

[0007] Therefore, it is necessary to develop and design a corresponding feeding device with higher efficiency for screw materials without end caps and with an inward mounting hole at one end. Utility Model Content

[0008] The utility model aims to provide an automatic directional feeding device for a capless screw with a mounting hole at the end. By means of the feeding device, the special screw can be efficiently fed in a predetermined direction.

[0009] Specifically, the utility model adopts the following technical solutions:

[0010] An automatic directional feeding device for endless cap screws with mounting holes at the ends, comprising a base, a vibrating feeder arranged on the base, the vibrating feeder having a vibrating feeding tray, a discharge port at the top side of the vibrating feeding tray, a sorting mechanism arranged at the discharge port, the sorting mechanism comprising an infeed guide frame for leading the screw workpiece out of the discharge port of the vibrating feeding tray and two discharge guide frames for conveying the screw workpiece backwards, a sorter arranged between the infeed guide frame and the discharge guide frame; channels for the screw workpiece to slide are arranged on the infeed guide frame and the discharge guide frame, the infeed guide frame and the discharge guide frame are both inclined from top to bottom so that the material can slide from high to low along the channels of the infeed guide frame and the discharge guide frame;

[0011] The sorter includes a rotating disc-shaped main body, on which a number of workstations for carrying screw workpieces are symmetrically arranged at the center; in the central direction of each workstation, a mounting column matching the mounting hole of the screw workpiece is arranged; a supporting chassis is arranged at the bottom of the main body, and the supporting chassis has a notch relative to the main body, wherein the first discharge guide frame is arranged at a position corresponding to the notch, and the second guide frame is arranged at a position corresponding to the subsequent workstation of the first discharge guide frame.

[0012] In this device, the purpose of the vibrating loader is to arrange the screw workpieces in sequence. The purpose of the sorting mechanism is to screen and classify the workpieces that meet the orientation and those that do not.

[0013] The two discharging guide frames are used to guide the workpieces in two directions respectively, and utilize the height difference to enable the workpieces to slide in the channels therein.

[0014] The disc-shaped body is used to sort the two types of workpieces one by one; the purpose of the mounting column is to cooperate with the workpiece with the mounting hole facing inward, so that the workpiece can be clamped by the mounting column and will not fall easily. The workpiece with the mounting hole facing outward will fall down at the gap of the bearing base and enter the first discharge guide frame, while the workpiece that adheres to the second discharge guide frame with the help of the mounting column will enter the second guide frame.

[0015] Preferably, a flip plate is provided at the workstation, and the flip plate is arranged on the main body on both sides of the workstation through a flip axis. The flip plate naturally flips outwards due to unequal moments on both sides of the flip axis.

[0016] The purpose of the flip plate is to sort the two types of workpieces more smoothly.

[0017] Preferably, the bearing chassis is located at the notch and is provided with an inclined guide portion for guiding the flip plate to return to its original position. Since the flip plate will flip downward, it needs to be returned to its original position so that it can be retracted into the station of the main body for transporting workpieces in the next cycle.

[0018] Preferably, the length of the turning plate inside the turning shaft is shorter than that outside the turning shaft, so as to ensure that the turning plate will automatically turn outward at the notch without support at the bottom to unload the workpiece.

[0019] Preferably, the thickness of the main body is greater than the outer diameter of the screw workpiece, so as to facilitate accommodating the workpiece.

[0020] Preferably, a guide frame for guiding the screw workpiece into the channel in the discharging guide frame is provided at the entrance of the discharging guide frame. The guide frame is used to guide the workpiece into the channel.

[0021] Preferably, the main body has arc-shaped edges on both sides of the workstation outlet.

[0022] Preferably, a direction adjustment mechanism is also provided at the first discharge guide frame; the direction adjustment mechanism includes a first direction channel and a second direction channel, the second direction channel is located below the first direction channel, and a hook is provided at the outlet of the first direction channel, the hook is hingedly arranged, and the hook matches the inner mounting hole of the screw workpiece.

[0023] Since the direction of the screw workpiece entering the first discharge guide rack is inconsistent with the direction of the workpiece entering the second discharge guide rack, it is necessary to adjust the direction of the screw workpiece through a direction adjustment mechanism so that the directions of the two screw workpieces are consistent.

[0024] Compared with the prior art, the beneficial effects of the utility model are: the device can quickly sort and feed screw workpieces with an inner mounting hole at one end and a uniform outer diameter as a whole; and the feeding device is different from the traditional method of feeding workpieces that meet the direction and returning those that do not meet the direction to the vibration plate; after the workpieces in this case come out of the vibration plate, they are all used for feeding, which improves the feeding efficiency, thereby reducing the use of vibration feeders and reducing working noise.

DETAILED DESCRIPTION

[0031] The representative embodiments shown in the accompanying drawings will now be further refined. It should be understood that the following description is not intended to limit the embodiments to a preferred embodiment. On the contrary, it is intended to cover alternatives, modifications and equivalents that may be included in the essence and scope of the embodiments defined by the appended claims.

[0032] The complete solution of this application is as follows:

[0033] An automatic directional feeding device for endless cap screws with mounting holes at the ends, such as Figure 1 As shown, it includes a base 1, on which a vibrating loader 2 is arranged. The vibrating loader 2 has a vibrating loading tray 3, and the top side of the vibrating loading tray 3 has a discharge port 4, and a sorting mechanism 5 is arranged at the discharge port 4.

[0034] like Figure 2 As shown, the sorting mechanism 5 includes a feed guide frame 6 for leading the screw workpiece out from the discharge port 4 of the vibrating loading tray 3 and two discharge guide frames 7 for conveying the screw workpiece backwards, and a sorter 8 is arranged between the feed guide frame 6 and the discharge guide frame 7; channels for the screw workpiece to slide are arranged on the feed guide frame 6 and the discharge guide frame 7, and the feed guide frame 6 and the discharge guide frame 7 are inclined from top to bottom so that the material can slide from high to low along the channels of the feed guide frame 6 and the discharge guide frame 7;

[0035] The sorter 8 includes a rotating disc-shaped main body 9, which is driven by an additional driving motor (omitted here). The thickness of the main body 9 is greater than the outer diameter of the screw workpiece, so as to facilitate the accommodation of the screw workpiece. A plurality of workstations 10 for carrying the screw workpiece are centrally symmetrically arranged on the main body 9; the main body 9 has arc-shaped edges on both sides of the exit of the workstation 10.

[0036] In the center direction of each workstation 10, a mounting column 11 matching the mounting hole of the screw workpiece is provided; a bearing chassis 12 is provided at the bottom of the main body 9, and a notch 13 is formed in the bearing chassis 12 relative to the main body 9, wherein the first discharge guide frame 7 is provided at a position corresponding to the notch 13.

[0037] like Figure 3 and Figure 4 As shown, after further improvement, a flip plate 14 is provided at the station 10, and the flip plate 14 is provided on the main body 9 on both sides of the station 10 through a flip shaft 15. The flip plate 14 is naturally flipped outwards due to the unequal torque on both sides of the flip shaft 15. The supporting chassis 12 is located at the notch 13, and is provided with an inclined guide portion 16 for guiding the flip plate 14 to return to its original position upwards. The length of the flip plate 14 on the inner side of the flip shaft 15 is less than the outer side.

[0038] In the above structure, a guide frame for guiding the screw workpiece into the channel inside the discharging guide frame 7 is also provided at the entrance of the discharging guide frame 7 .

After the screw workpiece is discharged from the first direction channel 19, its inner mounting hole is hooked by the hook, and the screw workpiece continues to move forward until its tail falls from the first direction channel 19 and falls into the second direction channel 20, at which time, the direction of the entire screw workpiece changes and slides downward.

[0040] The device can quickly sort and feed screw workpieces with hexagonal mounting holes at one end and the same outer diameter as a whole; and the feeding device is different from the traditional one that feeds workpieces that meet the direction and returns those that do not meet the direction to the vibration plate; after the workpieces in this case come out of the vibration plate, they are all used for feeding, which improves the feeding efficiency, thereby reducing the use of the vibration loader 2 and reducing the working noise.

[0041] It is obvious to those skilled in the art that certain modifications, combinations and variations can be made based on the above teachings.
