Description

Technical Field

[0001] The utility model relates to the technical field of capping equipment, in particular to a capping equipment capable of automatically capping. Background Art

[0002] After the material is filled, the bottle body containing the material needs to be capped. When the current screw capping equipment is in use, the bottle cap moves from the high end of the upper cover device to the low end with the cap opening facing downward. The bottle cap at the low end is tilted at a predetermined angle as a whole and partially suspended. The suspended part of the bottle cap can be hooked by the bottle body that moves below the low end through the belt conveyor, so that the bottle cap is driven by the moving bottle body and moves away from the upper cover device. Then the bottle body pre-installed with the bottle cap is conveyed by the belt conveyor to the cap screwing device, and the cap screwing device screws the bottle cap onto the bottle body.

[0003] When designing some bottle caps, the cap body extends downward to form a tube body. Such bottle caps need to be assembled with the bottle body in a manner that the tube body is inserted into the bottle body and the cap body is screwed onto the bottle body. Due to the design of the tube body, the current capping device is not suitable for such bottle caps. Usually, the staff needs to manually cap the bottle cap, which has a high labor cost.

The first detection member 512 is used to detect whether the signal radiation direction passes through a bottle body. The first interception assembly 513 includes a first interception member 5131 and a first belt-moving member 5132. The first interception member 5131 is installed on the first belt-moving member 5132 and can be driven by the first belt-moving member 5132 to move to or away from the direction in which the bottle body is transported by the conveying device 20 and moves to the bottom of the distribution assembly 121. The first limiting member 5111 and the first interception member 5131 are spaced apart and the spacing distance is adapted to the size of the outer diameter of a bottle body. The automatic capping device further comprises a controller 60, the first detection member 512 is communicatively connected to the controller 60, the first belt-moving member 5132 is controllably connected to the controller 60, and the controller 60 can control the operation of the first belt-moving member 5132 according to the feedback of the first detection member 512 so that the first belt-moving member 5132 drives the first intercepting member 5131 to move to or away from the direction where the bottle is transported by the conveying device 20 and moves to the direction below the dispensing assembly 121. When the first detection member 512 detects the bottle and the dispensing mechanism 12 performs the pre-installation operation, the first limiting member 5111 and the first intercepting member 5131 both remain on the trajectory of the bottle being transported by the conveying device 20 and confine a bottle between the two.

[0069] After the dispensing mechanism 12 completes a round of pre-installation operation, the first limiting member 5111 is driven by the first driving member 5112 to move the bottle body pre-installed with the bottle cap away from the bottom of the dispensing assembly 121 by the conveying device 20 and move toward the direction of the cover body rotating device 30, so that the bottle body pre-installed with the bottle cap on the side of the first limiting member 5111 close to the first limiting member 5111 can be driven by the conveying device 20 to move toward the cover body rotating device 30 to transfer the bottle body pre-installed with the bottle cap in time, and then the first limiting member 5111 is driven to move back to the direction in which the bottle body pre-installed with the bottle cap is conveyed by the conveying device 20, and at the same time, the first detection member 512 does not detect the bottle body, and the controller 60 receives feedback and controls the first belt moving member 5132 to operate so that the first belt moving member 5132 drives the first intercepting member 5131 to move 5131 moves away from the bottle body being conveyed by the conveying device 20 and moves toward the direction below the distribution assembly 121. The bottle body located on the side of the first intercepting member 5131 away from the first limiting member 5111 is driven by the conveying device 20 to make a bottle body move through the direction of the radiation signal of the first detection member 512. The first detection member 512 detects the bottle body and feeds back to the controller 60. The controller 60 controls the first belt moving member 5132 to operate so that the first belt moving member 5132 is driven to move back to the direction in which the bottle body is conveyed by the conveying device 20, so as to confine a bottle body between the first limiting member 5111 and the first intercepting member 5131, thereby intermittently transferring material to the distribution mechanism 12 individually, so that the bottle caps can correspond to the bottle bodies one by one, effectively avoiding the invalid delivery of bottle caps and the situation that the bottles are conveyed away without bottle caps.

[0070] Preferably, the first detection element 512 is implemented as an infrared sensor.

[0071] Preferably, the first driving member 5112 and the first belt shifting member 5132 are both implemented as cylinders.

[0072] refer to Figure 1 , Figure 2 and Fig. 9, the limiting device 50 also includes a second limiting mechanism 52, which is located between the first limiting mechanism 51 and the cover body rotating device 30. The second limiting mechanism 52 is used to limit the bottles pre-installed with bottle caps transmitted by the conveying device 20, so that multiple bottles pre-installed with bottle caps can be transmitted to the cover body rotating device 30 one by one, so as to prevent the bottles pre-installed with bottle caps transmitted by the conveying device 20 and moved to the cover body rotating device 30 from interfering with the operation of the cover body rotating device 30 during the process in which the cover body rotating device 30 fixes a bottle body with the first bottle fixing mechanism 31 and the cover body rotating mechanism 32 drives the cover body covered on the top of the bottle body to rotate and tighten it on the bottle body. In this way, by setting the second limiting mechanism 52, the capping operation can be carried out smoothly. In addition, during this process, the conveying device 20 does not need to be stopped, and the operation is simpler than the method of controlling the operating state of the conveying device 20.

[0073] The second limiting mechanism 52 includes a second limiting assembly 521, which includes a second limiting member 5211 and a second driving member 5212. The second limiting member 5211 is mounted on the second driving member 5212 and can be driven by the second driving member 5212 to move to or away from the direction in which the bottle body pre-installed with the bottle cap is transported by the conveying device 20 and moves toward the cap rotating device 30. When the second limiting member 5211 is driven by the second driving member 5212 to move to the direction in which the bottle body pre-installed with the bottle cap is transported by the conveying device 20 to the cap rotating device 30, and the cap rotating device 30 performs the capping operation, the second limiting member 5211 can intercept the remaining bottle body pre-installed with the bottle cap to prevent it from moving toward the cap rotating device 30.

[0074] The second limiting mechanism 52 also includes a second detection member 522 and a second interception assembly 523. The second detection member 522 can radiate a signal to the bottle body pre-installed with a bottle cap transmitted by the conveying device 20, and the second limiting member 5211 is used to detect whether the signal radiation direction moves through a bottle body pre-installed with a bottle cap. The second interception assembly 523 includes a second interception member 5231 and a second belt shifter 5232. The second interception member 5231 is installed on the second belt shifter 5232 and can be driven by the second belt shifter 5232 to move to or away from the direction where the bottle body pre-installed with the bottle cap is conveyed by the conveying device 20 and moves toward the cover body rotating device 30. The second limiting member 5211 and the second interception member 5231 are spaced apart and the spacing distance is adapted to the size of the outer diameter of a bottle body. The second limiting member 5211 is located between the second interception member 5231 and the cover body rotating device 30.

[0075] The second detection member 522 is communicatively connected to the controller 60, and the second belt-moving member 5232 is controllably connected to the controller 60. The controller 60 can control the second belt-moving member 5232 to operate according to the feedback of the second detection member 522 so that the second belt-moving member 5232 drives the second intercepting member 5231 to move to or away from the direction where the bottle body pre-installed with the bottle cap is conveyed by the conveying device 20 and moves toward the cap body rotating device 30. When the second detection member 522 detects the bottle body and the cap body rotating device 30 performs the capping operation, the second intercepting member 5231 and the second limiting member 5211 are both kept on the trajectory of the bottle body pre-installed with the bottle cap conveyed by the conveying device 20 and a bottle body pre-installed with the bottle cap is confined between the two.

[0076] After the cap rotating device 30 completes a round of capping operation, the second limiting member 5211 is driven by the second driving member 5212 to move away from the direction in which the bottle body pre-installed with the bottle cap is conveyed by the conveying device 20 and moves toward the cap rotating device 30, so that the bottle body pre-installed with the bottle cap on the side of the second blocking member 5231 close to the second limiting member 5211 can be driven by the conveying device 20 to move toward the cap rotating device 30, so as to timely supply the bottle body pre-installed with the bottle cap to the cap rotating device 30, and then the second limiting member 5211 is driven to move back to the direction in which the bottle body is conveyed by the conveying device 20, and at the same time, the second detecting member 522 does not detect the bottle body pre-installed with the bottle cap, and the controller 60 receives feedback and controls the second belt moving member 5232 to operate so that the second belt moving member 5232 drives the second intercepting member 5231 to move away from the bottle body pre-installed with the bottle cap being conveyed by the conveying device 20 The conveying device 20 conveys and moves toward the direction of the cap rotating device 30, and the bottle body pre-installed with the bottle cap located on the side of the second intercepting member 5231 away from the second limiting member 5211 is driven by the conveying device 20, so that a bottle body pre-installed with the bottle cap moves through the direction of the radiation signal of the second detecting member 522, and the second detecting member 522 detects the bottle body pre-installed with the bottle cap and feeds back to the controller 60, and the controller 60 controls the second belt moving member 5232 to operate so that the second belt moving member 5232 drives the second intercepting member 5231 to move back to the direction in which the bottle body pre-installed with the bottle cap is conveyed by the conveying device 20, so as to confine a bottle body pre-installed with the bottle cap between the second limiting member 5211 and the second intercepting member 5231, thereby intermittently feeding a single material to the cap rotating device 30, so that the cap rotating device 30 can screw the caps on multiple bottles pre-installed with bottle caps in an orderly manner.

[0077] Preferably, the second detection element 522 is implemented as an infrared sensor.

[0078] Preferably, the second driving member 5212 and the second belt shifting member 5232 are both implemented as cylinders.
