Description

Technical Field

[0001] The invention relates to the technical field of packaging, and in particular to a capping device and a capping equipment for closing a one-piece cap. Background Art

[0002] One-piece cap refers to a bottle cap in which the cap and the cap base are connected together through the side. The cap base of the one-piece cap is a sealing component, which is used to be fully assembled with the bottle body after being closed with the cap.

[0003] When the one-piece cover is closed, the pressure head presses down for the first time, and the cover seat is pressed against the positioning seat by the pressure head to prevent the cover seat from tilting up when the cover is flipped over. After the cover is flipped over to a certain angle, the pressure head needs to be separated from the cover seat to prevent the pressure head from hindering the cover from continuing to flip toward the cover seat. At this time, since a force needs to be applied to the cover seat toward the cover seat, the cover seat is not easy to tilt up. When the cover is flipped over and is about to be closed with the cover seat, the pressure head presses down for the second time, and the pressure head presses against the cover cap, thereby pressing the cover cap tightly against the cover seat. In order to avoid the pressure head from damaging the cover cap and the cover seat, the pressure head needs to adapt to the thickness of the cover seat when pressing down for the first time, so that the pressure head just presses on the cover seat, and the pressure head needs to adapt to the superimposed thickness of the cover cap and the cover seat when pressing down for the second time, so that the pressure head just presses on the cover cap. Therefore, the heights of the first and second pressing down of the pressure head are different, and the height difference between the first and second pressing down of the pressure head matches the thickness of the cover cap.

[0004] At present, the pressing head is usually guided by the groove of the cam plate to press down for the first time and the second time, so that the pressing head can be pressed down to different heights. The groove is designed in advance during production so that the height difference between the pressing head at the first time and the pressing head at the second time matches the thickness of the cap. However, for different one-piece caps, the thickness of the cap may be different, and the groove of the cam plate is finalized during production and can only be applied to the thickness of the cap. Moreover, it is difficult to disassemble and assemble when installed on the machine, which makes it difficult to change the height difference between the pressing head at the first time and the pressing head at the second time, resulting in one device being able to adapt to caps of one thickness and having a small scope of application.

[0049] See also Figures 1 to 3 One embodiment of the present invention provides a capping device, including: a capping device for closing a connected cover.

[0050] Wherein, the capping device for closing the one-piece cover comprises:

[0051] A machine platform 10, on which a first track 11 and a second track 12 are arranged;

[0052] A plurality of positioning seats 20, the positioning seats 20 are movably arranged on the machine platform 10, and the positioning seats 20 are used to support the cover seat 81 of the one-piece cover 80;

[0053] A first slide 30, the first slide 30 is slidably matched with the first track 11, a pressing head assembly 31 is detachably provided on the first slide 30, and the pressing head assembly 31 is movably connected to the first slide 30;

[0054] A second slide seat 40, the second slide seat 40 is slidably matched with the second track 12, and a pressure rod 41 is detachably provided on the second slide seat 40;

[0055] The driving assembly 50 is drivingly connected to the positioning seat 20, the first slide 30 and the second slide 40. The positioning seat 20 is driven by the driving assembly 50 to move to the first capping station, the flipping station and the second capping station in sequence. The first slide 30 is driven by the driving assembly 50 to move to the first capping station, the flipping station and the second capping station along the first track 11 in sequence. The second slide 40 is driven by the driving assembly 50 to move to the first capping station, the flipping station and the second capping station in sequence along the second track 12;

[0056] When the first slide 30 is located at the first capping station, the first slide 30 is at the first capping position relative to the positioning seat 20, and the pressing head assembly 31 presses the cover seat 81 of the one-piece cover 80 located on the positioning seat 20, thereby preventing the cover seat 81 of the one-piece cover 80 from tilting relative to the positioning seat 20 when the cover is flipped. At this time, since the relative positions of the first slide 30 and the positioning seat 20 are determined, according to the different thicknesses of the cover seat 81, different pressing head assemblies 31 can be replaced, so that when the first slide 30 reaches the first capping position, the pressing head assembly 31 can be adapted to stably press the cover seat 81 without damaging the cover seat 81.

[0057] In this embodiment, the cover closing device further includes a plurality of flip cover push rods 60 and a telescopic assembly for driving the flip cover push rods 60 to move. The flip cover push rods 60 are arranged on one side of the positioning seat 20. When the positioning seat 20 is in the first capping station, the flip cover push rods 60 extend and push the cap 82 of the one-piece cover 80 to flip until the cap 82 rotates to one side of the pressure head. The telescopic assembly can be a cylinder, an electric cylinder or a hydraulic cylinder, etc., and its output shaft is connected to the flip cover push rods 60.

[0058] When the first slide 30 is located at the flipping station, the first slide 30 is in the first avoidance position relative to the positioning seat 20, and the press head assembly 31 is separated from the cover seat 81 of the one-piece cover 80 on the positioning seat 20, so as to avoid the press head assembly 31 from interfering with the cover cap 82 of the one-piece cover 80 from covering the cover seat 81 of the one-piece cover 80. In this embodiment, the cover closing device further includes a flip plate 70, which is fixedly arranged on the machine 10 and located at the flipping station. When the positioning seat 20 passes through the flipping station, the press head assembly 31 is separated from the cover seat 81 and avoids the flip plate 70, so that the flip plate 70 can pass between the positioning seat 20 and the press head assembly 31, and the cover cap 82 abuts against the flip plate 70. As the positioning seat 20 moves, the cover plate is restricted by the flip plate 70 and flips toward the cover seat 81. When the positioning seat 20 leaves the flipping station, the cover cap 82 has flipped to a position close to the cover seat 81, or the cover cap 82 is roughly covered with the cover seat 81.

[0059] When the second slide 40 is located at the second capping station, the second slide 40 is in the second capping position relative to the positioning seat 20, and the pressing rod 41 abuts against the pressing head assembly 31 and drives the pressing head assembly 31 to move toward the positioning seat 20, so that the pressing head assembly 31 presses against the cap 82 of the one-piece cover 80 located on the positioning seat 20, so that the cap 82 is pressed against the cover seat 81 to achieve the closing of the cover. At this time, since the relative position of the second slide 40 and the positioning seat 20 is determined, according to the different thicknesses of the cap of the cover seat 81, different pressing rods 41 can be replaced, so that when the second slide 40 reaches the second capping position, the pressing rod 41 can push the pressing head assembly 31 to a suitable distance, so that the pressing head assembly 31 can adapt to stably press the cap 82 without damaging the cap 82 and the cover seat 81.

[0060] In the prior art, due to the groove limitation of the cam plate 13, the position where the pressure head can be lowered during the first and second capping is fixed, but the position difference between the two capping is fixed. For example, for the one-piece cover a, the distance between the position where the cover seat 81 of the one-piece cover a bears the pressure of the pressure head assembly 31 and the positioning seat 20 is 2 cm, and the distance between the position where the cover cap 82 of the one-piece cover a bears the pressure of the pressure head assembly 31 and the positioning seat 20 is 3 cm. During the first capping, the pressure head moves to a position 202 cm away from the positioning seat, and the position difference between the two capping is 1 cm. During the second capping, the pressure head moves to a position 203 cm relative to the positioning seat, but for the one-piece cover a, the pressure head moves to a position 203 cm away from the positioning seat. Cover b, the distance between the position where the cover seat 81 of the one-piece cover b is pressed by the pressure head assembly 31 and the positioning seat 20 is 2 cm, and the distance between the position where the cap 82 of the one-piece cover b is pressed by the pressure head assembly 31 and the positioning seat 20 is 2.9 cm. Since the position difference between the two capping operations is 1 cm, the cap 82 will be over-tightened during the second capping operation, causing damage to the cap 82, and it is impossible to replace the pressure head so that the pressure head can just press the cap 82 during the second capping operation. The only way to adjust the position difference between the two capping operations is to replace the cam plate 13. However, the cam plate 13 is large in size and is connected to multiple components, making it difficult to disassemble. Therefore, it cannot adapt to caps 82 of different thicknesses.

[0061] In the present invention, at the first capping station, the first slide 30 drives the pressing head assembly 31 to press the cover seat 81 of the one-piece cover, and the pressing head assembly 31 can be replaced to adapt to cover seats 81 of different thicknesses; and at the second capping station, the pressing head assembly 31 is driven by the pressing rod 41 on the second slide 40 to press the cover cap 82 of the one-piece cover, and the pressing head assembly 31 can be adapted to cover caps 82 of different thicknesses by replacing different pressing rods 41. For example, for one-piece cover a, the distance between the position where the cover seat 81 of one-piece cover a bears the pressure of the pressure head assembly 31 and the positioning seat 20 is 2 cm, the distance between the position where the cover cap 82 of one-piece cover a bears the pressure of the pressure head assembly 31 and the positioning seat 20 is 3 cm, the pressure head assembly 31 moves to a position 202 cm away from the positioning seat in the first capping station, and moves to a position 203 cm relative to the positioning seat in the second capping station; for one-piece cover b, the distance between the position where the cover seat 81 of one-piece cover b bears the pressure of the pressure head assembly 31 and the positioning seat 20 is 2 cm, the distance between the position where the cover cap 82 of one-piece cover b bears the pressure of the pressure head assembly 31 and the positioning seat 20 is 2.9 cm, and only different pressure rods 41 need to be replaced so that The pressure rod 41 is slightly longer by 0.1 cm, so that in the second capping station, the pressure rod 41 can push the pressure head assembly 31 to move to a position 202.9 cm relative to the positioning seat; and for the one-piece cover c, the distance between the position where the cover seat 81 of the one-piece cover c bears the pressure of the pressure head assembly 31 and the positioning seat 20 is 2.1 cm, and the distance between the position where the cap 82 of the one-piece cover c bears the pressure of the pressure head assembly 31 and the positioning seat 20 is 3.1 cm. Different pressure heads can be replaced to make the pressure head slightly shorter by 0.1 cm, so that in the first capping station, the pressure head assembly 31 moves to a position 202.1 cm away from the positioning seat, and in the second capping station, the pressure rod 41 pushes the pressure head assembly 31 to still move to a position 203.1 cm relative to the positioning seat. In summary, the pressure head assembly 31 of different lengths is replaced according to the specifications and shape of the cover seat 81, so that the pressure head assembly 31 can stably press against the cover seat 81, and the pressure rod 41 of different lengths is replaced according to the specifications and shape of the cap 82, so that after the pressure rod 41 pushes the pressure head assembly 31, the pressure head assembly 31 can stably press against the cap 82, so that the cap 82 and the cover seat 81 of the one-piece cover can be better adapted to be pressed tightly.

[0062] The method of guiding the first slide 30 or the second slide 40 to approach the positioning seat 20 can be appropriately designed according to actual needs. For example, the first slide 30 or the second slide 40 can be driven by a cylinder to move toward the positioning seat 20, or a third track can be set on the machine 10 to guide the positioning seat 20 to approach the first slide 30 or the second slide 40 by the third track; in this embodiment, when the first slide 30 moves to the first capping station, the first slide 30 moves to the first capping position relative to the positioning seat 20 under the guidance of the first track 11; when the first slide 30 moves to the flipping station, the first slide 30 moves to the first avoidance position relative to the positioning seat 20 under the guidance of the first track 11; when the second slide 40 moves to the second capping station, the second slide 40 moves to the second capping position relative to the first slide 30 under the guidance of the first track 11.

[0063] See also Figure 1 , Figure 4 and Figure 5 The formation mode of the first track 11 and the second track 12 can select a suitable design according to actual needs. For example, in some optional embodiments, a cam plate 13 is provided on the machine 10, and the first track 11 and the second track 12 are arranged around the cam plate 13. The driving assembly 50 includes a rotating seat 51 and a driving motor 52. The rotating seat 51 is rotatably provided on the machine 10, and the driving motor 52 is drivingly connected to the rotating seat 51. The positioning seat 20, the first slide seat 30 and the second slide seat 40 are all connected to the rotating seat 51. In this embodiment, the first track 11 is a first groove formed on the cam plate 13, the second track 12 is a second groove formed on the cam plate 13, the first slide seat 30 is provided with a roller movably connected to the first groove, and the second slide seat 40 is provided with a roller movably connected to the second groove.

[0064] In some optional embodiments, when the first slide 30 is located at the second capping station, the first slide 30 is in the third capping position relative to the positioning seat 20. When the first slide 30 is in the third capping position, the distance between the first slide 30 and the positioning seat 20 is greater than the distance between the first slide 30 and the positioning seat 20 when the first slide 30 is in the first capping position, thereby allowing the first slide 30 to move to a suitable position so that the pressure head assembly 31 is close to the positioning seat 20 and will not be driven by the first slide 30 to squeeze the cap 82. It is convenient for the pressure rod 41 to push the pressure head assembly 31 a short distance to drive the pressure head assembly 31 to press the cap 82. Of course, the first slide 30 can also maintain its position relative to the positioning seat 20 without approaching the positioning seat 20.

[0065] In some optional embodiments, the positioning seat 20 is driven by the driving component 50 to move to the first capping station, the flipping station, the second capping station and the discharging and feeding station in sequence, the first slide 30 is driven by the driving component 50 to move to the first capping station, the flipping station, the second capping station and the discharging and feeding station in sequence along the first track 11, and the second slide 40 is driven by the driving component 50 to move to the first capping station, the flipping station, the second capping station and the discharging and feeding station in sequence along the second track 12. In this embodiment, the first track 11 and the second track 12 are ring-shaped, and the discharging and feeding stations are arranged in a circular shape. The material station is connected to the first capping station, so that the positioning seat 20, the first slide 30 and the second slide 40 all move in a cycle along the first capping station, the flipping station, the second capping station and the discharging and feeding stations in sequence; when the first slide 30 is located at the discharging and feeding station, the first slide 30 is in the second avoidance position relative to the positioning seat 20, and an avoidance space is formed between the pressure head assembly 31 and the positioning seat 20, so that the one-piece cover 80 can be smoothly detached from the positioning seat 20 and the next one-piece cover 80 can be smoothly positioned by the positioning seat 20, avoiding the pressure head assembly 31 from interfering with the loading and unloading of the one-piece cover 80.

[0066] In some optional embodiments, a positioning channel 32 is provided on the first slide 30, and part of the second slide 40 or part of the pressure rod 41 is movably inserted into the positioning channel 32. The positioning channel 32 can position the second slide 40 or the pressure rod 41 relative to the first slide 30, so that the pressure rod 41 can accurately press the pressure head assembly 31, and during the movement of the first slide 30 and the second slide 40, the second slide 40 or the pressure rod 41 is prevented from being offset from each other with respect to the first slide 30, thereby facilitating the maintenance of the position between the pressure rod 41 and the first slide 30.

[0067] See also Figure 6 and Figure 7 In order to prevent the pressing head assembly 31 from impacting the cover seat 81, in some optional embodiments, a first guide rail 33 and a first movable seat 34 are provided on the first slide seat 30, the first movable seat 34 slides with the first guide rail 33, a first elastic member 35 is provided between the first movable seat 34 and the first slide seat 30, the pressing head assembly 31 is detachably connected to the first movable seat 34, and the pressing head assembly 31 is movably connected to the first movable seat 34, and the first slide seat 30 can drive the pressing head assembly 31 to move through the first movable seat 34.

[0068] When the first slide 30 is located at the first capping station, the first slide 30 is in the first capping position relative to the positioning seat 20, and the first slide 30 drives the pressure head assembly 31 to press against the cover seat 81 of the integrated cover 80 located on the positioning seat 20 through the first movable seat 34. When the pressure head assembly 31 initially contacts the cover seat 81, the pressure head assembly 31 stops moving, and the first slide 30 and the first movable seat 34 cooperate to drive the first elastic member 35 to produce elastic deformation. The elastic force of the first elastic member 35 can play a buffering role, so that the force applied by the first slide 30 to the pressure head assembly 31 through the first movable seat 34 gradually increases, thereby avoiding the pressure head assembly 31 from generating a strong impact on the cover seat 81. In addition, when the pressure head assembly 31 is separated from the cover seat 81, the first elastic member 35 can also play a role in resetting the first movable seat 34.

[0069] See also Figure 6 and Figure 7 In order to prevent the pressing head assembly 31 from impacting the cover seat 81, in some optional embodiments, a second guide rail 341 and a second movable seat 342 are provided on the first movable seat 34, and the second movable seat 342 slides with the second guide rail 341. A second elastic member 343 is provided between the first movable seat 34 and the second movable seat 342. The pressing head assembly 31 is movably connected with the first movable seat 34 through the second movable seat 342. The first slide seat 30 can drive the second movable seat 342 to move through the first movable seat 34, thereby realizing that the first slide seat 30 drives the pressing head assembly 31 to move, and the pressing head assembly 31 is detachably connected to the second movable seat 342, thereby realizing the detachable assembly of the pressing head assembly 31 and the first slide seat 30.

[0070] When the first slide seat 30 is located at the first capping station, the first slide seat 30 drives the second movable seat 342 to move through the first movable seat 34 , and the second movable seat 342 drives the pressing head assembly 31 to press against the cover seat 81 of the integrated cover 80 located on the positioning seat 20 . When the second slide seat 40 is located at the second capping station, the pressing rod 41 abuts against the second movable seat 342 and drives the pressing head assembly 31 to move toward the positioning seat 20 through the second movable seat 342. When the pressing head assembly 31 initially contacts the cap 82, the pressing head assembly 31 stops moving, and the first movable seat 34 and the second movable seat 342 drive the second elastic member 343 to produce elastic deformation. The first movable seat 34 and the second movable seat 342 cooperate to drive the second elastic member 343 to produce elastic deformation. The elastic force of the second elastic member 343 can play a buffering role, so that the force applied by the first movable seat 34 to the pressing head assembly 31 through the second movable seat 342 gradually increases, thereby avoiding the pressing head assembly 31 from generating a strong impact on the cap 82. In addition, when the pressing head assembly 31 is separated from the cap 82, the second elastic member 343 can also play a role in resetting the second movable seat 342.

[0071] In this embodiment, a first limiting portion 344 is also provided on the first movable seat 34. When the first sliding seat 30 is located at the first capping station, the first limiting portion 344 of the first movable seat 34 cooperates with the side of the second movable seat 342 away from the positioning seat 20 to limit the second movable seat 342 from moving away from the positioning seat 20, thereby maintaining the position of the second movable seat 342 relative to the first movable seat 34, and preventing the second movable seat 342 from moving relative to the first movable seat 34 and affecting the position of the pressing head assembly 31.

[0072] In this embodiment, the first movable seat 34 is also provided with a second limiting portion 345. When the first slide 30 is located at the second capping position and when the pressure rod 41 pushes the second movable seat 342 to move, the first limiting portion 344 cooperates with the side of the first slide 30 away from the positioning seat 20, so that when the pressure rod 41 pushes the second movable seat 342, the position of the first movable seat 34 relative to the first slide 30 is limited and will not move, thereby preventing the first movable seat 34 from moving relative to the first slide 30 and affecting the position of the pressing head assembly 31.

[0073] See also Figure 6 , Figure 7 and Figure 8 In order to adapt to the shape design of the one-piece cover 80 and improve the stability of pressing the one-piece cover 80, in some optional embodiments, the pressing head assembly 31 includes a pressing sleeve 311 and a pressing block 312, the pressing block 312 is located in the pressing sleeve 311, and a part of the pressing block 312 extends out of the pressing sleeve 311, and the pressing sleeve 311 is detachably arranged on the second movable seat 342, so as to achieve a detachable connection with the first slide seat 30. The second movable seat 342 is provided with a third guide rail 3421 and a movable rod 3422, and the movable rod 3422 is slidably matched with the third guide rail 3421, and a third elastic member 3423 is provided between the second movable seat 342 and the movable seat of the movable rod 3422, and the pressing head is detachably arranged on the movable rod 3422, so as to achieve a detachable connection with the first slide seat 30.

[0074] In this embodiment, the shape of the one-piece cover 80 is as follows: the top of the cover seat 81 is provided with an oil guide ring 83, a cover opening 84 and a sealing plate 85 (refer to the soy sauce bottle cover), the oil guide ring 83 is arranged around the cover opening 84, the sealing plate 85 is arranged in the cover opening 84, and a pull ring is provided on the sealing plate 85, which is convenient for the user to pull the sealing plate 85 off the cover seat 81 to open the cover opening 84, and the cover cap 82 is engaged with the oil guide ring 83 to close the cover.

[0075] When the first slide 30 is located at the first capping station, the first slide 30 drives the second movable seat 342 to move through the first movable seat 34, and the second movable seat 342 drives the pressing sleeve 311 and the movable rod 3422 to move toward the positioning seat 20, so that the pressure heads on the pressing sleeve 311 and the movable rod 3422 press against the cover seat 81 of the one-piece cover 80 located on the positioning seat 20, and the movable rod 3422 and the second movable seat 342 drive the third elastic member 3423 to produce elastic deformation. At the first cover pressing station, the end of the pressing sleeve 311 can abut against the oil guide ring 83 or the part of the cover seat 81 near the oil guide ring 83, thereby achieving stable pressing of the cover seat 81, and the pressing block 312 extends into the cover opening 84 and fits with the sealing plate 85, thereby further achieving stable pressing of the cover seat 81. When the pressing block 312 presses against the sealing plate 85, the pressing block 312 applies force to the third elastic member 3423 through the movable rod 3422, so that the movable rod 3422 cooperates with the second movable seat 342 to make the third elastic member 3423 produce elastic deformation, and the elastic force of the third elastic member 3423 makes the pressing block 312 fit more closely to the sealing plate 85, so that the positioning and pressing of the cover seat 81 is more stable. In addition, since the structure of the pressing sleeve 311 and the cover seat 81, especially the oil guide ring 83, is relatively close, the cover seat 81 is prevented from shaking left and right relative to the pressing sleeve 311. Therefore, when the pressing sleeve 311 is separated from the cover seat 81, the pressing sleeve 311 may drive the cover seat 81 to separate from the positioning seat 20. However, due to the design of the third elastic member 3423, when entering the flip cover station, the first slide seat 30 moves away from the positioning seat 20, so that the first movable seat 34 and the second movable seat 342 move away from the positioning seat 20, and then the pressure head assembly 31 is separated from the cover seat 81. In the process, when the pressing sleeve 311 is initially separated from the cover seat 81, due to the elastic force of the third elastic member 3423, the pressure head is still connected to the sealing plate 85, thereby preventing the pressing sleeve 311 from driving the cover seat 81 to move through the oil guide ring 83. After the pressing sleeve 311 is separated from the cover seat 81 and the oil guide ring 83, the pressure head is separated from the sealing plate 85 again, so that the separation of the pressure head assembly 31 and the cover seat 81 is more stable.

[0076] When the second slide 40 is located at the second capping station, the pressing rod 41 abuts against the second movable seat 342 and drives the second movable seat 342 to move toward the positioning seat 20, and the second movable seat 342 drives the pressing sleeve 311 and the movable rod 3422 to move toward the positioning seat 20, so that the pressing heads on the pressing sleeve 311 and the movable rod 3422 abut against the cap 82 of the one-piece cover 80 located on the positioning seat 20, or so that the pressing block 312 on the movable rod 3422 abuts against the cap 82 of the one-piece cover 80 located on the positioning seat 20. The pressing sleeve 311 may abut against the cap 82, or may not abut against the cap 82. The movable rod 3422 and the second movable seat 342 drive the third elastic member 3423 to produce elastic deformation, and the third elastic member 3423 plays a buffering role and also plays a role in resetting the pressing block 312.
