Description

Technical Field

[0001] The present invention relates to the technical field of bottle cap feeding, and specifically to an automatic feeding device for the production of plastic anti-counterfeiting wine bottle caps. Background Art

[0002] Bottle cap feeding refers to the process of transporting bottle caps from the storage area to the processing or assembly equipment during the production or packaging of bottle caps. In modern production, bottle cap feeding mostly uses automated equipment to improve efficiency and reduce manual intervention.

[0003] Bottle caps mainly include two categories: metal bottle caps and plastic bottle caps. For metal bottle caps, in order to ensure the firmness of the seal, a downward pressing and assembling form is generally used. For plastic bottle caps with relatively low self-strength, the stamping and assembling form may damage their appearance, so plastic bottle caps mostly use the method of rotating and tightening for assembly.

[0004] The existing structures applied to plastic bottle cap feeding mostly combine a bottle cap conveying and transferring structure with a cap screwing structure. The bottle caps on the conveying line are grabbed and transferred to the bottle mouth for tightening operations. For plastic bottle caps, anti-counterfeiting marks or expiration date marks are marked on their surfaces. It is difficult to avoid direct contact with these marks during the cap screwing process, so some marks may be damaged due to the rotational force. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic feeding device for the production of plastic anti-counterfeiting wine bottle caps to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: An automatic feeding device for the production of plastic anti-counterfeiting wine bottle caps, including a bottle body conveying mechanism, a bottle cap conveying mechanism, and a tightening mechanism. The bottle body conveying mechanism is used to convey bottles. The bottle cap conveying mechanism is arranged on the input side of the bottle body conveying mechanism and is used to convey bottle caps to the tightening mechanism. The tightening mechanism is arranged on one side of the bottle body conveying mechanism and is used to transfer the bottle cap to the bottle mouth and tighten it.

[0007] According to the above technical solution, the tightening mechanism includes a first frame. A transverse moving component is installed on the first frame. The driving end of the transverse moving component is installed with a longitudinal moving component. A tightening component is installed on the longitudinal moving component. The transverse moving component and the longitudinal moving component are respectively used to drive the tightening component to move horizontally and vertically. The tightening component is used to tighten the bottle cap.

[0008] According to the above technical solution, the tightening assembly includes a rotating shaft, a first motor, and a claw clip. One end of the rotating shaft is connected to the first motor, and the other end of the rotating shaft is connected to the claw clip. The claw clip is used for clamping the bottle cap. Several long inclined edges are arranged at intervals on the clamping surface of the claw clip. The long inclined edges include a column body, a guiding slope, and a pressing head. The height of the column body is higher than the surface of the clamping surface of the claw clip. The pressing head is arranged at the top of the column body, and the guiding slope is closely arranged against the pressing head, so that one side of the top of the pressing head is inclined.

[0009] According to the above technical solution, several straight rib strips are arranged on the circumference of the bottle cap surface. The marks on the bottle cap are generally located at the circumferential position, that is, at the top of the straight rib strips and at the gaps between two straight rib strips.

[0010] According to the above technical solution, a set of adjusting grooves are formed on the clamping surface of the claw clip. Sliders are slidably arranged in the adjusting grooves. Several short inclined edges are arranged at intervals on the sliders. The short inclined edges have the same structure as the long inclined edges, and the length of the short inclined edges is shorter than that of the long inclined edges.

[0011] According to the above technical solution, several springs are connected to one side of the slider, and the other ends of the springs are connected to the inner wall of the adjusting groove. An adsorption box is connected to the other side of the slider. The adsorption box is open towards the inner wall of the adjusting groove. A magnetic adsorption module is laid inside the adsorption box. An electromagnetic block is arranged on the inner wall of the adjusting groove corresponding to the adsorption box. The adjusting groove is slidably matched with the electromagnetic block.

[0012] According to the above technical solution, in the initial state, the slider is located at the center position of the clamping surface of the claw clip; the electromagnetic block is used to attract the adsorption box to drive the slider to move. When the electromagnetic block is energized, it generates a magnetic force to attract the magnetic adsorption module in the adsorption box, and the adsorption box moves towards the electromagnetic block, thereby driving the short inclined edges to deviate from the center position, so that the two short inclined edges can avoid the marked position in the middle of the bottle cap and only clamp the upper or lower edge position of the bottle cap; when the electromagnetic block is powered off, the attraction between the adsorption box and the electromagnetic block is released, and the spring pulls the slider back.

[0013] According to the above technical solution, the bottle cap conveying mechanism includes a second frame. A vibrating disk is arranged on the second frame. A linear vibrator is arranged on the outlet side of the vibrating disk. A feeding rail is connected to the outlet side of the linear vibrator. A bottle cap conveying component is arranged on the outlet side of the feeding rail.

[0014] According to the above technical solution, the bottle cap conveying component includes a conveyor belt, a set of rotating wheels, a second motor, and a centering module. The rotating wheels are respectively rotatably arranged on the first frame and the second frame. The conveyor belt is sleeved on the rotating wheels. The second motor is connected to one of the rotating wheels.

[0015] According to the above technical solution, the centering module includes a mounting frame. The mounting frame is arranged in a concave structure and the lower surface is located below the conveyor belt. The upper surface of the mounting frame is higher than the surface of the conveyor belt. A first guiding piece and a second guiding piece are fixed on the upper side of the mounting frame. The first guiding piece and the second guiding piece are respectively used for centering the bottle cap in the left and right directions.

[0016] According to the above technical solution, a slide rail is provided on the mounting bracket. An electric push rod is fixed on one side inside the slide rail, and a moving block is slidably arranged inside the slide rail. A push plate is connected to the lower side of the moving block. A separation plate is arranged on one side of the second guide piece. The distance between the separation plate and the second guide piece is greater than the diameter width of the bottle cap. One end of the separation plate is guided to the edge of the conveyor belt. A micro camera is arranged on the slide rail for observing the surface state of the bottle cap.

[0017] According to the above technical solution, the bottle body conveying mechanism includes a third rack. A conveyor belt and a transmission component cooperating therewith are arranged on the third rack. A baffle is arranged on the conveyor belt relative to the tightening mechanism. The baffle is cooperatively provided with a cylinder, and a limit clamp is arranged at the driving end of the cylinder for cooperatively limiting the bottle body with the baffle.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: In the present invention, by providing the long inclined edges on the claw clip, when the bottle cap is clamped, under the guidance of the inclined abutting head and the guiding slope, the side surface of the straight rib on the surface of the bottle cap is abutted by the abutting head, avoiding the direct contact between the marked position and the clamping surface of the claw clip, effectively ensuring the integrity of the mark. By providing the short inclined edges with adjustable positions, the clamping position of the short inclined edges relative to the bottle cap can be adjusted according to the mark type, further avoiding the damage of the mark on the surface of the bottle cap during the tightening process and improving the quality of the processed finished product. By providing the alignment module, while assisting in adjusting the moving direction of the bottle cap, defective bottle caps can be effectively excluded and collected, improving the quality of bottle cap feeding.

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 - 13, the present invention provides a technical solution: an automatic feeding device for producing plastic anti-counterfeiting wine bottle caps, including a bottle body conveying mechanism 1, a bottle cap conveying mechanism 2, and a tightening mechanism 3. The bottle body conveying mechanism 1 is used for conveying bottles. The bottle cap conveying mechanism 2 is arranged on the input side of the bottle body conveying mechanism 1 and is used for conveying bottle caps to the tightening mechanism 3. The tightening mechanism 3 is arranged on one side of the bottle body conveying mechanism 1 and is used for transferring the bottle cap to the bottle mouth and tightening it.

[0036] The tightening mechanism 3 includes a first frame 31. A transverse moving component 32 is installed on the first frame 31. A driving end of the transverse moving component 32 is installed with a longitudinal moving component 33. A tightening component is installed on the longitudinal moving component 33. The transverse moving component 32 and the longitudinal moving component 33 are respectively used for driving the tightening component to move horizontally and vertically. The tightening component is used for tightening the bottle cap.

[0037] As Figures 2 - 6 shown, the tightening component includes a rotating shaft 34, a first motor 35, and a claw clip 36. One end of the rotating shaft 34 is connected to the first motor 35, and the other end of the rotating shaft 34 is connected to the claw clip 36. The claw clip 36 is used for clamping the bottle cap. Several long inclined edges 37 are arranged at intervals on the clamping surface of the claw clip 36. The long inclined edge 37 includes a column body 371, a guiding slope 372, and a resisting head 373. The height of the column body 371 is higher than the surface of the clamping surface of the claw clip 36. The resisting head 373 is arranged at the top of the column body 371, and the guiding slope 372 is arranged on one side of the resisting head 373, so that one side of the top of the resisting head 373 is inclined.

[0038] Based on the above structure, the supplementary description is as follows: Several straight rib strips 4 are arranged circumferentially on the surface of the bottle cap. The marks on the bottle cap are generally located at the circumferential position, that is, at the top of the straight rib strips 4 and at the gaps between two straight rib strips 4. When the bottle cap is clamped, under the guidance of the inclined resisting head 373 and the guiding slope 372, the side surface of the straight rib strip 4 is resisted by the resisting head 37, avoiding the direct contact between the marked position and the clamping surface of the claw clip 36, effectively ensuring the integrity of the mark. The structures of the transverse moving component 32 and the transverse moving component 32 are not unique. In this application, the form of screw rod movement is preferably adopted.

[0039] Furthermore, as Figures 7 - 9 shown, a set of adjusting grooves 361 are formed on the clamping surface of the claw clip 36. A slider 362 is slidably arranged in the adjusting grooves 361. Several short inclined edges 363 are arranged at intervals on the slider 362. The short inclined edges 363 have the same structure as the long inclined edges 37, and the length of the short inclined edges 363 is shorter than that of the long inclined edges 37.

[0040] Further, several springs 364 are connected to one side of the slider 362, the other ends of the springs 364 are connected to the inner wall of the adjustment groove 361, an adsorption box 365 is connected to the other side of the slider 362, the adsorption box 365 is open towards the inner wall of the adjustment groove 361, a magnetic adsorption module is laid inside the adsorption box 365, an electromagnet 366 is arranged on the inner wall of the adjustment groove 361 corresponding to the adsorption box 365, and the adjustment groove 361 is in sliding fit with the electromagnet 366.

[0041] It should be supplemented and explained that: in the initial state, the slider 362 is located at the center position of the clamping surface of the claw clip 36. The electromagnet 366 is used to attract the adsorption box 365 to drive the slider 362 to move. When the electromagnet 366 is energized, it generates a magnetic force to attract the magnetic adsorption module in the adsorption box 365, and the adsorption box 365 moves towards the electromagnet 366, so as to drive the short inclined edge 363 to deviate from the center position, so that the two short inclined edges 363 can avoid the marked position in the middle of the bottle cap and only clamp the edge position on the upper side or the lower side of the bottle cap; when the electromagnet 366 is powered off, the attraction between the adsorption box 365 and the electromagnet 366 is released, and the spring 364 pulls the slider 362 back.

[0042] As Figure 10 shown, the bottle cap conveying mechanism 2 includes a second frame 21, a vibrating disk 22 is arranged on the second frame 21, a linear vibrator 23 is arranged on the outlet side of the vibrating disk 22, a feeding rail 24 is connected to the outlet side of the linear vibrator 23, and a bottle cap conveying component 25 is arranged on the outlet side of the feeding rail 24.

[0043] In one embodiment, as Figure 11 shown, the bottle cap conveying component 25 includes a conveyor belt 251, a set of rotating wheels 252, a second motor 253 and a centering module. The rotating wheels 252 are respectively rotatably arranged on the first frame 31 and the second frame 21, the conveyor belt 251 is sleeved on the rotating wheels 252, and the second motor 253 is connected to one of the rotating wheels 252. In actual operation, the conveyor belt 251 is arranged in cooperation with the outlet side of the feeding rail 24 and the tightening mechanism 3, and is used to transfer the sorted bottle caps to the tightening mechanism 3.

[0044] As Figure 12 shown, the centering module includes a mounting frame 26. The mounting frame 26 is arranged in a concave shape and the lower surface is located below the conveyor belt 251. The upper surface of the mounting frame 26 is higher than the surface of the conveyor belt 251. A first guiding piece 261 and a second guiding piece 262 are fixed on the upper side of the mounting frame 26. The first guiding piece 261 and the second guiding piece 262 are respectively used for centering the bottle cap in the left and right directions.

[0045] Further, a slide rail 263 is provided on the mounting bracket 26. An electric push rod 264 is fixed on one side inside the slide rail 263. A moving block 265 is slidably arranged inside the slide rail 263. A push plate 266 is connected to the lower side of the moving block 265. A separation plate 267 is arranged on one side of the guide piece II 262. The distance between the separation plate 267 and the guide piece II 262 is greater than the diameter width of the bottle cap. One end of the separation plate 267 is guided to the edge of the conveyor belt 251. A micro camera 268 is arranged on the slide rail 263 for observing the surface state of the bottle cap.

[0046] It should be further noted that: the space between the separation plate 267 and the guide piece II 262 is the rejection channel. When the micro camera 268 detects that the surface state of the moving bottle cap does not meet the standard or there are defects in the marks on the bottle cap, the defective bottle cap is transferred to the rejection channel by controlling the push plate 266. The defective bottle cap falls from the edge of the conveyor belt 251 to the lower surface of the mounting bracket 26 for temporary storage. By default, the position set at the end of the separation plate 267 does not block the bottle cap moving on the side of the guide piece II 262, so that the qualified bottle cap enters the rejection channel. On the other hand, the guide piece I 261 is used for rough positioning of the bottle cap, and the push plate 266 is used to assist the guide piece II 262 to perform further fine positioning of the bottle cap. That is, after the bottle cap is restricted in the area between the guide piece I 261 and the guide piece II 262, the push plate 266 advances towards the guide piece II 262, so that the bottle cap is close to the surface of the guide piece II 262. According to different types of bottle caps, the advancing distance of the push plate 266 is different, which improves the flexibility of the limit.

[0047] As Figure 13 shown, the bottle body conveying mechanism 1 includes a frame III 11. A conveyor belt 12 and a transmission component 13 cooperating with it are arranged on the frame III 11. A baffle 121 is arranged on the conveyor belt 12 relative to the tightening mechanism 3. A cylinder 14 is arranged in cooperation with the baffle 121. A limit clamp 15 is arranged at the driving end of the cylinder 14 for limiting the bottle body in cooperation with the baffle 121.

[0048] The form of the transmission component 13 is not unique and can be in the form of a motor driving a gear.

[0049] A test camera 16 is installed on the outlet side of the conveyor belt 12 for detecting the tightening state of the bottle cap.

[0050] The specific implementation method is as follows:

[0051] Step 1: Bottle cap sorting. The vibrating disk 22 sorts the input bottle caps one by one.

[0052] Step 2: Feeding. The linear vibrator 23 conveys the sorted bottle caps to the conveyor belt 251, and at the same time, the bottles are fed at intervals from the conveyor belt 12.

[0053] Step 3: Alignment. During the conveying of the bottle caps, the alignment module adjusts the positions of the bottle caps and rejects the defective bottle caps detected simultaneously.

[0054] Step 4: Limiting. When a certain bottle moves to the tightening mechanism 3, the conveying stops. The cylinder 14 drives the limiting clamp 15 to press the bottle tightly against the side of the baffle 121 for limiting.

[0055] Step 5: Feeding. The tightening mechanism 3 moves to the position of the bottle cap to grab it. During this period, the grabbing state is adjusted according to the different types of marks on the bottle cap, and then it is transferred to the upper side of the bottle.

[0056] Step 6: Tightening. The first motor 35 is started to tighten the bottle cap on the corresponding bottle.

[0057] Step 7: Discharging. The bottle body conveying mechanism 1 moves the processed bottles to the side of the discharging port. After being detected by the test camera 16, they are then classified and collected.

[0058] Step 8: Repeat Steps 1 to 7.

[0059] Specifically, in Step 3, the micro camera 268 needs to detect and classify the bottle cap from the surface state and the mark state respectively. When the micro camera 268 identifies that there are damages on the surface of the bottle cap or the surface marks are unclear, the bottle cap is classified as a defective product and is transferred to the rejection channel through the push plate 266. When the micro camera 268 identifies that the surface of the bottle cap is intact and the surface marks are complete and clear, the bottle cap is a qualified product and can be fed for assembly. After the push plate 266 adjusts the feeding position of the bottle cap, the micro camera 268 feeds back the detected mark position and type to the tightening mechanism 3.

[0060] In Step 5, the tightening mechanism 3 makes adjustments according to the mark position and type: First, determine the mark position and lock the clamping surface of the claw clip 36 that needs to contact it. Then, the mark types are classified into simple types and complex types. Simple types are marks with a small coverage area such as the production date, and complex types are marks with a large coverage area such as pictures.

[0061] For simple type marks, the tightening mechanism 3 can be tightened in the normal state. At this time, the electromagnet block 366 is not powered on, and the short inclined edge 363 is in the middle position and directly contacts the surface of the bottle cap. For complex type marks, after the tightening mechanism 3 positions to the corresponding clamping surface of the claw clip 36, the corresponding electromagnet block 366 is powered on to pull the short inclined edge 363 to both sides, making the middle of the clamping surface facing the mark empty. The corresponding short inclined edge 363 only clamps and limits the upper and lower sides of the bottle cap, avoiding damaging the surface marks of the bottle cap as much as possible and improving the surface quality of the finished product.

[0062] Furthermore, to confirm the gripping status of the bottle cap, several pressure units are added to the surface of the slider 362. In step three, the micro camera 268 first confirms the length and height of the bottle cap, corresponding to the position and contact range of the gripping claw 36. Specifically, the bottle cap should be in a downward-facing position with the opening surface horizontal before loading. The height of the pressure signal distribution determines whether the bottle cap meets the loading requirements. When the bottle cap surface contacts the gripping surface of the gripping claw 36, the height range of the detected pressure signal corresponds to the bottle cap height. Assuming the bottle cap height is H and the detected pressure value distribution height is h, when H=h, the bottle cap surface is completely in contact with the gripping claw 36 surface. When h<H, it indicates that one end of the bottle cap is tilted, so that only a portion of the bottle cap is in contact with the gripping claw 36 surface. In this case, the bottle cap should be reloaded to ensure that the bottle cap is parallel to the ground. When h>H, it indicates that the bottle cap is deformed or the gripping claw 36 has grasped an object other than the bottle cap, and manual confirmation is required.

[0063] Furthermore, based on the above judgment, each column of pressure signals is grouped, and the highest pressure signal and the lowest pressure signal in each group are taken to compare whether the highest pressure signals and the lowest pressure signals are the same. If there is a deviation, it indicates that the claw clamp 36 is over-clamped, causing the bottle cap to deform.
