Abstract
Description
Technical Field
[0001] The invention relates to paintbrush production equipment, in particular to a brush tip loading system. Background Art
[0002] The paintbrush consists of a brush head and a pen holder. In the process of mass production of pens, the brush heads and pen holders need to be classified and assembled. Since the pen holders are long, they can be neatly stacked in the pen holder bin by the operator in advance; but the brush head has a bundle of hairs at one end and a metal sleeve at the other end. The overall size is relatively short, which is not convenient for the operator to sort in advance. Many brush heads are dumped in the huge brush head bin and are bound to be in a disordered state. The premise of industrial assembly is to take out many messy and disordered brush heads from the brush head bin one by one and then transport them to the assembly station.
[0003] Existing technologies such as Figure 7 As shown, the pen tips coming out of the silo are stored on the V-groove belt 100, and are transmitted to the end of the feeding device through the belt transmission. The positioning push rod 101 arranged on the side extends from the outer end face of the V-groove belt to push the pen tips to the assembly station for assembly with the pen holder. At this time, the positioning push rod is in the V-groove belt. The V-groove belt can only move forward after the positioning push rod is completely retracted from the V-groove belt. The whole process takes a long time, which affects work efficiency. In addition, the transmission rigidity of the V-groove belt is poor. After a period of use, the V-groove belt is easy to deform, resulting in misalignment between it and the positioning push rod, unstable feeding, and affecting production. Summary of the invention
[0004] The purpose of the present invention is to provide a pen tip loading system with stable feeding and improved pen tip and pen holder assembly efficiency in view of the deficiencies in the prior art.
[0005] To achieve the above purpose, the technical solution adopted by the pen tip loading system of the present invention is:
[0006] A pen tip loading system comprises a frame, wherein the frame is provided with a vibrating plate for orienting the pen tip, the discharging end of the vibrating plate is connected with a secondary conveying mechanism through a primary conveying mechanism, the pen tip is transferred to the secondary conveying mechanism through the primary conveying mechanism, the secondary conveying mechanism comprises a fixed plate fixed to the frame in the middle, a moving plate is sleeved on the outer side of the fixed plate, the moving plate is provided with a driving device for driving it to rotate, the driving device drives the moving plate to intermittently index and rotate around an axis, a plurality of V-shaped supporting plates for carrying the pen tip are equally divided on the upper end surface of the moving plate, the V-shaped supporting plate is provided with a first cylinder for driving it to reciprocate up and down, a fence fixed to the frame is provided on the outer side of the moving plate, the fixed plate is provided with a positioning mechanism corresponding to the fence, the positioning mechanism pushes the pen tip toward the fence for positioning the radial position of the end of the pen tip on the moving plate, a clamping mechanism fixed to the fixed plate is provided at the station after the positioning mechanism, the clamping mechanism comprises a slider and a second cylinder driving the slider to move up and down, the downward pressed slider and the raised V-shaped supporting plate fix the pen tip for assembling the pen holder. The metal sleeve at the tail of the pen tip is heavier than the hair bundle at the head. Under the action of the vibration disk, the tail of the pen tip is transported to the primary conveying mechanism in an orderly manner, and then transferred to the inner end of the V-shaped support plate of the secondary conveying mechanism through the primary conveying mechanism. The pen tip rotates intermittently with the driving device around the axis of the moving disk. When the pen tip is rotated to the in-position position, the in-position mechanism pushes the pen tip to the edge of the moving disk, and the pen tip rotates to the assembly position along the enclosure. The first cylinder lifts the V-shaped support plate, and the second cylinder presses down the slider. The pressed slider and the lifted V-shaped support plate fix the pen tip for assembling the pen holder. After the pen tip and pen holder are assembled, the slider and the V-shaped support plate are retracted at the same time, and the pen tip and pen holder continue to move forward without hindrance. The vertical movement distance of the slider and the V-shaped support plate is much smaller than the horizontal movement distance of the in-position push rod in the prior art, which greatly improves the assembly efficiency of the pen tip and pen holder. At the same time, the pen head rotates intermittently and indexedly around the axis of the disk along with the driving device, forming a rigid connection. After debugging, there will be no problem of pen head misalignment, the feeding is stable, and it does not affect production.

When the first sensor at the tail end detects the metal sleeve, the clamp grabs the pen tip, the rotating cylinder does not rotate, and is transported to the secondary conveying mechanism through the third cylinder. If the first sensor detects a bundle of fine hairs at the set position, the clamp grabs the pen tip and is first rotated 180° by the rotating cylinder, and then is transported to the secondary conveying mechanism through the third cylinder.
[0008] Preferably, the secondary conveying mechanism is provided with a plurality of workstations, including a feeding station, a positioning station, an assembly station and a material returning station.

[0010] Preferably, the positioning mechanism includes a push block and a fourth cylinder driving the push block to move left and right, and a guide block aligned with the V-shaped support plate is provided at the bottom of the push block. The push block pushes the pen tip toward the enclosure, shortens the distance before the pen tip and the pen holder are assembled, reduces the displacement of the pen holder after assembly, and prevents it from falling from the conveying device.

[0012] Preferably, a displacement sensor is provided at the lower side of the second sensor. When there are more than one pen tip in the V-shaped support plate at the in-position position, the pen tip pushed by the fourth cylinder will push the second sensor to displace, and the displacement sensor at the lower side will send out a signal when detecting the displacement of the second sensor. At this time, when the V-shaped support plate at the in-position position arrives at the assembly position, the first and second cylinders will not perform invalid actions, saving time and improving efficiency.

After debugging, there is no problem of pen tip misalignment, and the feeding is stable without affecting production.
[0017] 2.

[0020] 5. When there is more than one pen tip in the V-shaped pallet in the in-position position, the pen tip pushed by the fourth cylinder will push the second sensor to move.

[0032] The specific working process and principle of a pen tip feeding system: the metal sleeve at the tail of the pen tip is heavier than the hair bundle at the head. Under the action of the vibrating disk, the tail of the pen tip is transported to the conveyor belt in an orderly manner in front, and moves forward along the positioning guide groove fixed on the conveyor belt. When it reaches the set position, the first sensor detects the metal sleeve, the clamp clamps the pen tip, the rotating cylinder does not rotate, and is transferred to the secondary conveying mechanism through the third cylinder. If the first sensor detects the hair bundle at the set position, the clamp clamps the pen tip and is first rotated 180° by the rotating cylinder, and then transferred to the secondary conveying mechanism through the third cylinder. The clamp transfers the pen tip to the inner side of the V-shaped support plate at the moving disk feeding position to prevent the pen tip from being thrown out of the moving disk before it rotates to the positioning position. After the V-shaped support plate rotates intermittently with the moving disk, it reaches the pen tip positioning position, and the fourth cylinder is started. The push block cooperates with the guide block to push the pen tip to the set position. When the second sensor detects the metal sleeve, the pen tip rotates along the enclosure to the assembly position. When the pen tip is in the in-position position, the first cylinder lifts up the V-shaped support plate, and the second cylinder presses down the slider at the same time. The pressed slider and the lifted V-shaped support plate fix the pen tip for assembling the pen holder. After the pen tip and pen holder are assembled, the V-shaped support plate and the slider are retracted at the same time, and the pen tip and pen holder continue to move forward without hindrance; if the second sensor detects the hair bundle or does not detect the object, a signal is sent. At this time, when the V-shaped support plate in the in-position position arrives at the assembly position, the first and second cylinders will not perform invalid actions, saving time and improving efficiency; if there are more than one pen tip in the V-shaped support plate in the in-position position, the pen tip pushed by the fourth cylinder will push the second sensor to move, and when the displacement sensor on the lower side detects the displacement of the second sensor, a signal is sent. At this time, when the V-shaped support plate in the in-position position arrives at the assembly position, the first and second cylinders will not perform invalid actions, saving time and improving efficiency; if there are pen tips with their heads and tails reversed in the V-shaped support plate, the V-shaped support plate will be cleared out by the air blowing pipe at the material withdrawal position. The vertical moving distance of the V-shaped support plate and the slider is much smaller than the horizontal moving distance of the positioning push rod in the prior art, which greatly improves the assembly efficiency of the pen tip and the pen holder. At the same time, the pen tip rotates intermittently and indexingly around the axis of the disk with the driving device, forming a rigid connection. After debugging, there is no problem of pen tip misalignment, and the feeding is stable without affecting production.
