Description

Technical Field

[0001] The present invention relates to the technical field of packaging machinery, and particularly relates to a cap aligning machine for bottle caps. Background Art

[0002] The bottle caps of beer and beverage bottles are usually round bottle caps, including metal bottle caps, plastic bottle caps, and crown bottle caps. Usually, their specification feature is that the height h of the bottle cap < the diameter d of the bottle cap. In the bottle cap production and processing or the beer and beverage filling industries, in order to achieve large-scale automated production, the requirements for the output speed and stability of the bottle cap material flow are relatively high. Usually, a cap aligning machine is used to sort out the disordered round bottle caps into an arrangement with the cap openings facing the same direction and output them in sequence, so as to meet the working requirements of subsequent production or filling equipment. The existing cap aligning equipment usually adopts mechanisms such as a vibrating disk and an attitude adjustment slideway. By driving the bottle caps to move along the attitude adjustment slideway one by one and gradually adjusting the attitude, the orientations of the bottle caps are adjusted to be consistent.

[0003] However, the existing cap aligning equipment has a relatively complex structure. The attitude adjustment slideway needs to be strictly matched with the bottle caps of corresponding specifications and cannot be compatible with bottle caps of multiple specifications. When changing the bottle caps, the corresponding cap aligning mechanism needs to be replaced, and the equipment utilization rate is low. Summary of the Invention

[0004] Aiming at the defects of the existing technology, the present invention provides a cap aligning machine, which is a rotary disk type multi-station cap aligning equipment. With this equipment, round bottle caps with a height dimension h less than the diameter dimension d can be quickly and efficiently sorted from a disordered state into an arrangement with the cap openings facing the same direction and output in sequence. Only by adjusting the settings of individual components of the equipment can it adapt to bottle caps of different specifications, and the applicability is greatly improved.

[0005] The overall technical solution of the present invention is as follows:

[0006] A cap aligning machine, including a frame assembly,

[0007] A main shaft assembly is fixedly installed on the upper part of the top plate of the frame assembly, and a motor assembly is installed below the frame assembly. The main shaft assembly includes a main shaft and a turntable. With the axis of the main shaft as the center of the circle, a plurality of core shaft assemblies are evenly distributed on the circumference of the turntable. The motor assembly drives the main shaft to rotate, driving all the core shaft assemblies to rotate together;

[0008] A cylindrical cam is fixedly installed above the top plate of the frame assembly. The turntable is provided with a positioning disk and a linear bearing at each core shaft assembly. Under the combined action of the cylindrical cam and the positioning disk, the core shaft assembly can slide up and down in the linear bearing while revolving around the axis of the main shaft;

[0009] Above the turntable, a rotating disk is fixedly connected. The rotating disk has a convex conical structure. Above the rotating disk, there is a hopper assembly. The hopper assembly is supported on the upper end of the main shaft and is fixedly connected to the side of the frame assembly at the same time. A vibrating screen is arranged between the rotating disk and the hopper assembly;

[0010] An annular dial is fixedly installed on the outer edge above the turntable. The inner circumference of the dial is connected to the outer circumference of the rotating disk. A number of semi-circular card slots are evenly distributed along the circumference of the dial. A boss is arranged in the middle of the positions of every two semi-circular card slots. Below the position of each semi-circular card slot, a corresponding core shaft assembly is provided. A positioning block is arranged at the top of each core shaft assembly; Along the circumference of the dial, there are a cover inlet point, a front cover outlet point, and a rear cover outlet point. A guiding plate is arranged inside the dial at the cover inlet point. The distance between the guiding plate and the dial is slightly greater than the height of the bottle cap; At the front cover outlet point and the rear cover outlet point, a front cover outlet channel and a rear cover outlet channel are respectively arranged outside the turntable;

[0011] When the bottle cap unscrambling machine works, the bottle caps in the hopper assembly fall onto the upper surface of the rotating disk through the vibration of the vibrating screen and slide to the inner edge of the circumference of the dial; At the cover inlet point, the bottle caps with the cover opening facing vertically upward or vertically downward enter the space between the lower surface of the guiding plate and the upper surface of the dial, and then enter the position of a semi-circular card slot at the cover inlet point. The outer bottom surface of the bottle cap with the cover opening facing vertically upward is lifted by the corresponding positioning block, and the bottle cap with the cover opening facing vertically downward falls, and the inner bottom surface of the bottle cap contacts the corresponding positioning block; The bottle cap moves with the turntable to the front cover outlet point, and the corresponding core shaft assembly is at a high position. The bottle cap with the cover opening facing vertically upward is exported from the front cover outlet channel; The bottle cap moves with the turntable to the rear cover outlet point, and the corresponding core shaft assembly is at a low position. The bottle cap with the cover opening facing vertically downward is exported from the rear cover outlet channel; The front cover outlet channel and the rear cover outlet channel are respectively connected to the bottle cap conveying channels. One of the bottle cap conveying channels is used to flip the attitude of the bottle cap material flow by 180°, and then the bottle cap material flow is merged with the bottle cap material flow of the other bottle cap conveying channel.

[0012] The specific structures of the components of the present invention are introduced as follows:

[0013] The main shaft assembly is installed and fixed on the upper part of the top plate of the frame assembly through the bearing seat inside it; The motor assembly is installed and fixed inside the lower part of the frame assembly and drives the main shaft to rotate through gears or belts, chains, friction wheels, etc. or other transmission methods, and then drives all the components fixed on the main shaft to rotate together.

[0014] The turntable is fixedly connected to the main shaft; the positioning disk is fixed to the outside of the lower disk of the turntable, and a number of positioning grooves in the shape of an inverted "U" are evenly arranged on the circumference of the positioning disk; on the lower disk of the turntable, with the center of the disk as the center of the circle, a number of the linear bearings and the core shaft assemblies are evenly arranged. The linear bearings are fixed to the lower disk of the turntable, and each linear bearing is internally provided with one core shaft assembly; when the main shaft drives the turntable to rotate, under the combined action of the cylindrical cam and the positioning disk, all the core shaft assemblies can revolve around the axis of the main shaft while sliding up and down in the linear bearings.

[0015] The rotating disk is fixedly connected to the turntable as a whole; the hopper assembly is supported at the upper end of the main shaft by a bearing at the lower part, and is fixedly connected to the frame assembly through a side connecting plate at the same time.

[0016] Further, the core shaft assembly includes a mounting seat, on which an outer bearing, an inner bearing and a core shaft are fixedly installed, and the positioning block is fixed to the top of the core shaft by screws; the inner bearing cooperates with the cam groove on the outer circumferential surface of the cylindrical cam. When the turntable rotates, under the action of the cam groove of the cylindrical cam, the core shaft assembly slides up and down in the linear bearing; the outer bearing cooperates with the inverted "U" - shaped structure positioning groove at the circumferential position of the positioning disk, and the outer bearing slides up and down in the positioning groove to prevent the core shaft assembly from generating a self - rotation phenomenon around the axis of the core shaft while sliding up and down.

[0017] Further, the bottle cap aligning machine of the present invention is provided with a compressed air blowing device at the bottle cap feeding point, and the air outlet of the compressed air blowing device is aligned with the semi - circular card slot position of the dial.

[0018] Further, inner and outer fork plates are arranged in both the front bottle cap outlet channel and the rear bottle cap outlet channel for guiding the bottle caps out.

[0019] Further, the bottom surface of the front bottle cap outlet channel is flush with the upper surface of the dial, the bottom surface of the rear bottle cap outlet channel is flush with the upper surface of the turntable, and the bottom surface of the front bottle cap outlet channel is higher than the bottom surface of the rear bottle cap outlet channel, and the height difference is greater than the height of the bottle cap.

[0020] Further, the guiding plate is provided with a height - adjusting mechanism for adjusting the distance between the guiding plate and the dial.

[0021] The working principle of the bottle cap aligning machine of the present invention is:

[0022] During operation, pour the round bottle caps into the hopper assembly, and a part of the bottle caps first flow into the vibrating sieve. When the vibrating sieve vibrates, some of the bottle caps in the vibrating sieve fall onto the surface of the rotating disc. Under the action of the centrifugal force generated by the rotation of the rotating disc, all the bottle caps on the surface of the rotating disc flow outward in a circular motion. When the bottle caps pass through the guiding plate, the bottle caps with the cap openings facing vertically upward or vertically downward can enter directly below the guiding plate and are pushed into the indexing plate, while the bottle caps in other postures are blocked by the guiding plate and cannot enter directly below the guiding plate; as the rotating disc rotates, the bottle caps slide backward in the direction of rotation, are pushed and adjusted in posture by the new bottle caps, and after sliding one week, they are ready to enter below the guiding plate again.

[0023] The bottle caps that are shunted and enter below the guiding plate are blown by compressed air to the semi-circular slot positions of the indexing plate at the cap inlet point. Since there are bosses arranged between every two semi-circular slot positions, the bottle caps can only enter the slot positions. A mandrel assembly is arranged below each semi-circular slot position. When caps are being fed in, all the mandrel assemblies are in the high position, and the top surface of the positioning block is flush with the upper surface of the indexing plate.

[0024] When the bottle cap with the cap opening facing upward enters the semi-circular slot of the indexing plate, the bottom of the bottle cap contacts the top surface of the positioning block, and the bottle cap will not fall, and the bottle cap is in the high position on the surface of the positioning block. When the bottle cap with the cap opening facing downward falls into the slot of the indexing plate, due to the gap between the circular positioning block and the periphery of the semi-circular slot of the indexing plate, the bottle cap falls, and the cap wall inserts into this gap, and the inner bottom surface of the bottle cap contacts the top surface of the positioning block, and the bottle cap is in the low position.

[0025] Under the control of the cam groove of the cylindrical cam, within the area from the cap inlet point to the front cap outlet point, the mandrel assemblies are in the high position. When the bottle cap moves to the front cap outlet point, the inner and outer fork plates arranged in the front cap outlet channel are used to sequentially guide the bottle caps with the cap openings facing upward and in the high position into the front cap outlet channel one by one. Within the area from the front cap outlet point to the rear cap outlet point, the mandrel assemblies descend from the high position to the low position, and the bottle caps fall with the positioning blocks at the tops of the mandrel assemblies and stop falling when the mouth of the bottle cap contacts the upper surface of the turntable. When the bottle cap moves to the rear cap outlet point, the inner and outer fork plates arranged in the rear cap outlet channel are used to sequentially guide the bottle caps with the cap openings facing downward and in the low position into the rear cap outlet channel one by one.

[0026] When the main shaft rotates counterclockwise, a material flow of bottle caps with the cap openings facing upward is output inside the front cap outlet channel, and a material flow of bottle caps with the cap openings facing downward is output inside the rear cap outlet channel. The front and rear cap outlet channels are respectively connected to the bottle cap conveying channels. Use one of the conveying channels to flip the posture of the bottle cap material flow by 180°, and then converge it with the bottle cap material flow of the other conveying channel. After the combined material flow of the bottle caps, the cap openings all face the same direction and enter the subsequent process.

[0027] Compared with the prior art, the beneficial effects brought by the present invention include:

[0028] 1. This equipment is applicable to the work of sorting circular bottle caps with height h < diameter d. Using this equipment, the caps can be sorted from a disorderly state into an arrangement with the cap openings facing the same direction and output in sequence. By simply adjusting the height adjustment structure of the guiding plate, it can adapt to bottle caps of different height specifications as long as the height h of the bottle cap < diameter d, greatly improving the applicability.

[0029] 2. This equipment is equipped with two cap output channels. Through ingenious design, it outputs bottle caps in two postures, with the cap openings facing up and the cap openings facing down respectively. Then, using the conveying channel, one of the cap material flows is flipped 180° and merged with the caps from the other conveying channel to complete the work of sorting bottle caps. The entire equipment does not involve a posture adjustment slideway with overly complex structure, is easy to maintain, has a large processing capacity per unit time, and high working efficiency.

Detailed Implementation Modes

[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments, but it shall not be used as a basis for limiting the present invention.

[0041] See Figures 1-9 , the present invention provides a bottle cap aligning machine, which includes a frame assembly 2. A main shaft assembly 3 is fixedly installed on the upper part of the top plate of the frame assembly 2. A motor assembly 1 is installed below the frame assembly 2.

[0042] A cylindrical cam 30 is fixedly installed above the top plate of the frame assembly 2. The turntable 33 is provided with a positioning disc 34 and a linear bearing 39 at each mandrel assembly 4. Under the combined action of the cylindrical cam 30 and the positioning disc 34, the mandrel assembly 4 can slide up and down in the linear bearing 39 while revolving around the axis of the main shaft 32;

[0043] A rotating disc 36 is fixedly connected above the turntable 33. The rotating disc 36 has an upwardly convex conical structure. A hopper assembly 37 is provided above the rotating disc 36. The hopper assembly 37 is supported at the upper end of the main shaft 32 and is fixedly connected to the frame assembly 2 on its side. A vibrating screen 38 is provided between the rotating disc 36 and the hopper assembly 37;

[0044] An annular dial 35 is fixedly installed on the outer edge above the turntable 33. The inner circumference of the dial 35 is connected to the outer circumference of the rotating disc 36. The dial 35 is evenly distributed with a plurality of semi-circular grooves along the circumference. A convex platform is arranged in the middle between the positions of every two semi-circular grooves. The position below each semi-circular groove corresponds to a mandrel assembly 4. A positioning block 45 is provided at the top of each mandrel assembly 4; The dial 35 is provided with a cap inlet point A, a front cap outlet point B, and a rear cap outlet point C along the circumference. A guiding plate 5 is provided inside the dial 35 at the cap inlet point A. The distance between the guiding plate 5 and the dial 35 is slightly greater than the height of the bottle cap; A front cap outlet channel 6 and a rear cap outlet channel 7 are respectively provided outside the turntable 33 at the front cap outlet point B and the rear cap outlet point C;

[0045] When the cap aligning machine of the present invention is working, the caps 8 in the hopper assembly 37 fall onto the upper surface of the rotary disk 36 through the vibration of the vibrating screen 38 and slide to the inner edge of the circumference of the dial 35; at the cap feeding point A, the caps with the cap openings facing vertically upward or vertically downward enter the space between the lower surface of the guiding plate 5 and the upper surface of the dial 35, and then enter a semi-circular card slot position at the cap feeding point. The outer bottom surface of the cap with the cap opening facing vertically upward is lifted by the corresponding positioning block 45, and the cap with the cap opening facing vertically downward falls, and the inner bottom surface of the cap contacts the corresponding positioning block 45; the cap moves with the turntable 33 to the front cap discharging point B, and the corresponding mandrel assembly 4 is at a high position, and the cap with the cap opening facing vertically upward is discharged from the front cap discharging channel 6; the cap moves with the turntable 33 to the rear cap discharging point C, and the corresponding mandrel assembly 4 is at a low position, and the cap with the cap opening facing vertically downward is discharged from the rear cap discharging channel 7; the front cap discharging channel 6 and the rear cap discharging channel 7 are respectively connected to the cap conveying channels, and the attitude of the cap material flow in one of the cap conveying channels is flipped by 180°, and then converges with the cap material flow in the other cap conveying channel.

[0046] Further illustrate the structures of various parts of the present invention.

[0047] See Figure 3 , the main shaft assembly 3 is installed and fixed on the upper part of the top plate of the frame assembly 2 through the bearing seat 31 inside it; the motor assembly 1 is installed and fixed inside the lower part of the frame assembly 2, and drives the rotation of the main shaft through other transmission methods such as gears, belts, chains, friction wheels, etc., and then drives all the components fixed on the main shaft 32 to rotate together;

[0048] The turntable 33 is fixedly connected to the main shaft 32; the positioning disk 34 is fixed on the outer part of the lower disk of the turntable 33, and a number of inverted "U" - shaped positioning grooves are evenly arranged on the circumference of the positioning disk 34; on the lower disk of the turntable 33, a number of linear bearings 39 and mandrel assemblies 4 are evenly arranged with the disk center as the center of the circle. The linear bearings 39 are fixed on the lower disk of the turntable 33, and each linear bearing 39 internally houses a mandrel assembly 4; when the main shaft 32 drives the turntable 33 to rotate, under the combined action of the cylindrical cam 30 and the positioning disk 34, all the mandrel assemblies 4 can slide up and down in the linear bearings 39 while revolving around the axis of the main shaft 32.

[0049] The rotary disk 36 is fixedly connected to the turntable 33 as a whole; the hopper assembly 37 is supported by the bearing at the lower part on the upper end of the main shaft 32, and is fixedly connected to the frame assembly 2 through the side connecting plate at the same time.

[0050] See Figure 4, the mandrel assembly 4 includes a mounting base 40, on which an outer bearing 41, an inner bearing 42 and a mandrel 44 are fixedly installed. A positioning block 45 is fixed to the top of the mandrel 44 by screws. The inner bearing 42 cooperates with the cam groove on the outer peripheral surface of the cylindrical cam 30. When the turntable 33 rotates, the inner bearing 42 slides up and down in the linear bearing 39 under the action of the cam groove of the cylindrical cam 30. The outer bearing 41 cooperates with the inverted "U" - shaped structure positioning groove at the circumferential position of the positioning disk 34, and the outer bearing 41 slides up and down in the positioning groove to prevent the mandrel assembly 4 from rotating around the axis of the mandrel 44 while sliding up and down.

[0051] See Figure 2 , Figure 5 , this bottle cap aligning machine is provided with a compressed air blowing device at the cap inlet point A, and the air outlet of the compressed air blowing device is aligned with the semi - circular card slot position of the dial 35. Inner and outer fork plates are arranged in both the front cap outlet channel 6 and the rear cap outlet channel 7 for guiding the bottle caps out.

[0052] See Figures 7-9 , the bottom surface of the front cap outlet channel 6 is flush with the upper surface of the dial 35, the bottom surface of the rear cap outlet channel 7 is flush with the upper surface of the turntable 33, the bottom surface of the front cap outlet channel 6 is higher than the bottom surface of the rear cap outlet channel 7, and the height difference is greater than the height of the bottle cap. The guiding plate 5 is provided with a height - adjusting mechanism to adjust the distance between the guiding plate 5 and the dial 35.

[0053] See Figures 1-9 , introduce the working principle of the bottle cap aligning machine of the present invention:

[0054] During operation, the bottle caps 8 are poured into the hopper assembly 37, and part of the bottle caps first flow into the vibrating screen 38. When the vibrating screen 38 vibrates, some of the bottle caps in the vibrating screen 38 fall onto the surface of the rotating disk 36. As the rotating disk 36 rotates, the cap - aligning action is started. When the vibrating screen 38 stops vibrating, the bottle caps in the vibrating screen 38 stop falling, avoiding excessive accumulation of bottle caps on the upper surface of the rotating disk 36, thus affecting the normal cap - aligning action.

[0055] Under the action of the centrifugal force generated by the rotation of the rotating disk 36, all the bottle caps on the surface of the rotating disk 36 flow outward in the circumferential direction. When the bottle caps pass through the guiding plate 5, the bottle caps with the cap openings facing vertically upward or vertically downward can enter directly below the guiding plate 5 and are pushed into the dial 35, while the bottle caps in other postures are blocked by the guiding plate 5 and cannot enter directly below the guiding plate 5. As the rotating disk 36 rotates, the bottle caps slide backward in the rotating direction, are pushed and adjusted in posture by the new bottle caps, and after sliding one week, are ready to enter below the guiding plate 5 again.

[0056] Further specifically introduce the cap - splitting principle of the guiding plate: See Figure 5 , Figure 6, the distance between the lower surface of the guiding plate 5 and the upper surface of the dial 35 is H, and the distance H is set to be slightly greater than the cap height h (the clearance value Δ is generally preferably 0.2 - 1.5 mm). At this time, only the caps with the cap mouth facing vertically upward or vertically downward (i.e., Figure 6 the two cases (a) and (b) in Figure 6 can enter the space between the lower surface of the guiding plate 5 and the upper surface of the dial 35. When the round cap is in any other inclined posture (i.e., Figure 6 the two cases (e) and (f) in

[0057] ), or when the cap mouth is in a horizontal left or right direction posture (limited by the cap diameter d > the cap height h, i.e.,

[0058] the two cases (c) and (d) in

[0059] ), the cap cannot smoothly enter the space between the lower surface of the guiding plate 5 and the upper surface of the dial 35. Furthermore, during the rotation process, it is diverted by the guiding plate 5 to the surface of the rotating disc 36, and as the rotating disc 36 rotates, the cap slides backward. During the sliding process, it converges with the newly dropped caps, adjusts its posture during the rotation, and after rotating one week, it enters the lower part of the guiding plate assembly again.

[0060] When the main shaft 32 rotates counterclockwise, a cap material flow with the cap outlet facing upward is output inside the front cap outlet passage 6, and a cap material flow with the cap outlet facing downward is output inside the rear cap outlet passage 7. The front and rear cap outlet passages are respectively connected to the cap conveying passages. One of the conveying passages is used to flip the posture of the cap material flow by 180°, and then it converges with the cap material flow of the other conveying passage. After the confluence, the cap outlet of the cap material flow faces the same direction and enters the subsequent process.

[0061] So far, all the cap sorting actions of this equipment are completed, and the caps can enter the subsequent production process. This equipment quickly and efficiently sorts circular caps with a height dimension h smaller than the diameter dimension d from a disorderly state into an arrangement with the cap outlets facing the same direction and outputs them in sequence. It has strong applicability, is easy to maintain, and has high efficiency.

[0062] The above description is only a preferred example of the present invention, and does not impose any formal or substantial limitations on the present invention. All technical solutions within the concept of the present invention fall within the protection scope of the present invention. Any equivalent changes and modifications made to the above examples based on the essential technology of the present invention should also be regarded as within the protection scope of the present invention.
