Description

Technical Field

[0001] The utility model relates to liquid filling equipment, in particular to a clamping claw type filling equipment capable of replenishing and sucking liquid. Background Art

[0002] Liquid filling equipment is an automated machine that puts liquid into a container and covers the container. It is usually used to produce canned items such as packaged cans and liquid cosmetics.

[0003] In the prior art, the steps of the liquid filling equipment are generally to first convey the container to the filling position for filling, and then the container after filling is covered with the container cover by the component for conveying the container cover, and then the container cover is tightened on the container intactly by the component for detecting and tightening the cover, and finally the filling of the liquid is completed. However, the liquid filling equipment in the prior art often fills containers one by one, which is inefficient.

[0004] On the other hand, existing liquid filling equipment usually uses conveyor belts or card slots for conveying, but in the process of conveying containers, it usually undergoes the conversion of multiple components to facilitate filling in a limited space. This also requires that when the conveyor belt or card slot is fixed on the container, in order to facilitate the conversion of the container, it is necessary to leave room to avoid the container being too tightly fixed and unable to switch to the next component. In other words, the fixing method of existing liquid filling equipment is not stable enough, and the container may be offset or fall down as a whole, affecting the subsequent filling and capping processes.

[0005] In addition, during filling, since the liquid flow is controlled by fixing the opening and closing time of the valve, part of the liquid may be blocked by the valve or the pipe and not injected into the container, and then injected into the next container during the next filling process. Therefore, the error of the liquid capacity inside the container may exceed the predetermined error. In other words, the liquid capacity inside the container may be less than or greater than the predetermined amount. If it is less than the predetermined amount, the product will be short in weight, and if it is more than the predetermined amount, it may make it difficult for the container cap to block the container opening.

[0032] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0033] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0034] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0035] refer to Figures 1 to 6A clamp-type filling device with replenishable liquid suction according to a preferred embodiment of the utility model will be described in detail below. The clamp-type filling device with replenishable liquid suction is used to fill liquid into the container 80 from the container mouth 801 of the container 80, and tighten the container cover 90 on the container 80 to seal the container mouth 801 of the container 80.

[0036] like Figure 1 As shown, the clamp-type filling device capable of replenishing liquid includes a device body 10, a plurality of clamping jaw components 20, a liquid injection assembly 30, a replenishing suction assembly 40 and a capping assembly 50.

[0037] like Figure 1 As shown, the device body 10 includes a plurality of conveying members 11, a rotating table 12 and at least one first driving member 13, wherein the plurality of first driving members 13 are drivably connected to the conveying members 11 and the rotating table 12, respectively. The conveying member 11 has a conveying space 1101, and the conveying space 1101 is adapted to the container 80. The rotating table 12 is rotatably arranged at a position adjacent to the conveying member 11, so that the container 80 is transferred from the conveying member 11 to the rotating table 12, and then rotated to a predetermined position.

[0038] As an example, the conveying member 11 is implemented as a conveyor belt. The first driving member 13 is implemented as a driving motor.

[0039] like Figure 1 and Figure 2 As shown, each of the clamping jaw members 20 is installed on the side of the rotating table 12 corresponding to one of the conveying members 11, so that the clamping jaw member 20 clamps the container 80 from the conveying space 1101 of the conveying member 11 and rotates to the predetermined position following the rotating table 12.

[0040] It can be understood that, when the turntable 12 rotates under the drive of the first driving member 13, the clamping member 20 approaches one end of the conveying space 1101 so as to clamp and rotate the container 80 conveyed from one end of the conveying space 1101 to the other end. After the container 80 rotates through the liquid injection assembly 30, the supplementary suction assembly 40, and the screw cap assembly 50 to perform a series of filling operations, the container 80 is rotated to the predetermined position by the turntable 12.

[0041] like Figure 2As shown, each of the clamping jaw members 20 includes a trunk 21, a first clamping member 22, a second clamping member 23, a push-pull member 24 and a second driving member 25, wherein the trunk 21 is drivably connected to the second driving member 25 so that the trunk 21 can move up and down. The trunk 21 has a mounting end 211, and the trunk 21 is mounted on the side of the rotating platform 12 through the mounting end 211, and the other end of the trunk 21 extends away from the rotating platform 12, so that when the rotating platform 12 rotates, the other end of the trunk 21 can approach the conveying member 11, so that the clamping jaw member 20 can clamp the container 80 located in the conveying space 1101 and rotate the container 80 to the predetermined position.

[0042] By way of example, the second drive element 25 is implemented as a hydraulic cylinder.

[0043] The trunk 21 has a fixed claw end 212, one end of the first clamp 22 is fixed to the fixed claw end 212 of the trunk 21, and one end of the second clamp 23 is rotatably connected to the fixed claw end 212 of the trunk 21, so that the other end of the second clamp 23 is configured to be close to or separate from the end of the first clamp 22 away from the fixed claw end 212, thereby forming a clamping space 201 between the first clamp 22 and the second clamp 23, and the clamping space 201 is used to clamp the container 80. When the rotating table 12 rotates the clamping member 20 to be close to the conveying member 11, the clamping space 201 is connected to the conveying space 1101, so that the container 80 located in the conveying space 1101 is clamped by the clamping member 20 and rotated to the predetermined position.

[0044] One end of the push-pull member 24 can be telescopically fixed to the trunk 21, and the other end of the push-pull member 24 can be rotatably connected to the second clamp 23, so that the second clamp 23 rotates with one end connected to the fixed claw end 212 as the rotation point, so that when the push-pull member 24 is extended, it abuts against the first clamp 22, and when the push-pull member 24 is shortened, it moves away from the first clamp 22, thereby adjusting the size of the clamping space 201 so that the container 80 can be better clamped.

[0045] By way of example, the push-pull member 24 is implemented as a hydraulic cylinder.

[0046] It can be understood that, during the pushing and pulling process of the push-pull member 24, the container 80 can be clamped by the clamping claw member 20, and because the push-pull member 24 presses against the second clamping member 23, the container 80 is firmly clamped in the clamping space 201, and there is no possibility that the container 80 will be displaced or fall down as a whole.

[0047] like Figure 3 As shown, the injection assembly 30 includes a plurality of injection parts 31, which are installed above the rotation path of the container 80 so that when the container 80 moves below the injection part 31, the clamping jaw member 20 moves upward so that each injection part 31 is inserted into the container mouth 801 of the container 80 to inject liquid into the interior of the container 80.

[0048] By way of example, the filling piece 31 is implemented as a liquid tank with a valve pipeline.

[0049] like Figure 4 As shown, the replenishing and sucking assembly 40 includes at least one measuring member 41, a plurality of liquid replenishing members 42 and a plurality of liquid absorbing members 43, wherein the measuring member 41 can measure the amount of liquid in the container 80. The liquid replenishing members 42 and the liquid absorbing members 43 are installed above the rotation path of the container 80, and when the container 80 rotates to below the liquid replenishing members 42 and the liquid absorbing members 43, one of the liquid replenishing members 42 and the liquid absorbing member 43 are simultaneously inserted into the container 80 from one of the container openings 801. After the measuring member 41 measures the amount of liquid in the container 80, according to a predetermined amount of the standard, when the amount of liquid is less than the predetermined amount, the liquid replenishing member 42 replenishes the container 80; when the amount of liquid is more than the predetermined amount, the liquid absorbing member 43 absorbs the liquid from the container 80, thereby ensuring that the amount of liquid inside the container 80 meets the standard.

[0050] As an example, the liquid replenishing component 42 and the liquid absorbing component 43 are both implemented as a liquid tank with a valve pipeline.

[0051] like Figure 5 and Figure 6 As shown, the screw cap assembly 50 is installed above the rotation path of the container 80. When the container 80 rotates to the bottom of the screw cap assembly 50, the screw cap assembly 50 screws the container cap 90 onto the container mouth 801 of the container 80, thereby completing the filling of the container 80, and then moves to the predetermined position through the rotation of the rotating table 12.

[0052] It can be understood by those skilled in the art that when the clamping member 20 on the rotating table 12 is rotated and approaches the conveying space 1101, the container 80 is conveyed by the conveying member 11 from one end of the conveying space 1101 to the other end close to the rotating table 12, so that the container 80 is clamped by the clamping member 20 and is driven to rotate by the rotating table 12; when the container 80 is rotated to below the liquid injection member 31, the clamping member 20 moves up so that the liquid injection member 31 is inserted into the container port 801 to inject liquid into the container 80; after the liquid injection is completed, the clamping member 20 moves down and continues to drive the container 80 to rotate , the container 80 is rotated to below the liquid replenishing part 42 and the liquid absorbing part 43, the clamping jaw member 20 moves up, so that the liquid replenishing part 42 and the liquid absorbing part 43 are inserted into the container mouth 801, and after the measuring member 41 measures the amount of liquid in the container 80, the container 80 is replenished or absorbed according to the standard liquid amount; after the liquid replenishment or absorption is completed, the clamping jaw member 20 moves down, and the container 80 is rotated to below the screw cap assembly 50, and the screw cap assembly 50 places the container cover 90 on the container 80 and tightens it to block the container mouth 801; after the screw cap is completed, the container 80 is rotated to the predetermined position.

[0053] Preferably, the device body 10 further includes at least one output member 14, the output member 14 is drivably connected to the first driving member 13, and each output member 14 is arranged corresponding to one of the clamping members 20. The output member 14 has an output space 1401, and the output space 1401 is adapted to the container 80. The output member 14 is installed at an adjacent position of the rotating table 12, and when the clamping member 20 is close to the output member 14, the output space 1401 is connected to the clamping space 201, so that the container 80 transferred from the conveying member 11 to the rotating table 12 is rotated to the output space 1401 of the output member 14, and then transferred to the predetermined position, so as to facilitate subsequent processing operations.

[0054] By way of example, the output element 14 is implemented as a conveyor belt.

[0055] In an equally preferred embodiment, one end of the push-pull member 24 is fixed to the first clamp 22, the other end of the push-pull member 24 is fixed to the second clamp 23, and the first clamp 22 is rotatably connected to the fixed claw end 212 of the trunk 21, so that the push-pull member 24 can simultaneously drive the first clamp 22 and the second clamp 23 during the pushing and pulling process to clamp the container 80.

[0056] Preferably, if Figure 3As shown, the injection component 30 also includes at least one third driving member 32, and the third driving member 32 is drivably connected to the injection member 31, so that the injection member 31 is driven to move up and down. In this way, the container 80 can be injected without moving up, and when the injection member 31 and the container 80 are close to each other, the speed of the injection process is accelerated.

[0057] By way of example, the third drive element 32 is implemented as a hydraulic cylinder.

[0058] Preferably, if Figure 4 As shown, the replenishing and suction component 40 also includes at least one fourth driving member 44, and the fourth driving member 44 is drivably connected to the liquid replenishing member 42 and the liquid absorbing member 43, so that the liquid replenishing member 42 and the liquid absorbing member 43 are driven to move up and down. In this way, the container 80 can replenish or absorb liquid without moving up, and when the liquid replenishing member 42 and the liquid absorbing member 43 are close to the container 80, the speed of the liquid replenishing or liquid absorbing process is accelerated.

[0059] Preferably, the measuring member 41 is implemented as a load-bearing device, and when the container 80 is below the fluid replenishing member 42 and the fluid absorbing member 43, the measuring member 41 is installed directly below the container 80, and the clamping member 20 moves downward to drive the container 80 to be placed on the measuring member 41, and at the same time the clamping member 20 releases the container 80, so that the measuring member 41 can accurately measure the amount of liquid in the container 80, thereby allowing the fluid replenishing member 42 and the fluid absorbing member 43 to perform fluid replenishment or fluid absorbing operations on the container 80.

[0060] More preferably, the measuring member 41 is drivably connected to the fourth driving member 44, so that the measuring member 41 can move up and down, so that when the container 80 rotates above the measuring member 41, the measuring member 41 moves up to lift the container 80, so that the container 80 can complete the measurement without moving down, and the measurement process is accelerated when the container 80 moves down.

[0061] By way of example, the fourth drive element 44 is implemented as a hydraulic cylinder.

[0062] Preferably, if Figure 5 and Figure 6As shown, the screw cap assembly 50 includes a plurality of cap placing bodies 51, at least one cap pushing member 52, a plurality of cap screwing members 53 and a plurality of fifth driving members 54, wherein the fifth driving member 54 is drivably connected to the cap placing bodies 51, the cap pushing members 52 and the cap screwing members 53. The cap pushing member 52 is mounted on one end of the plurality of cap placing bodies 51, and the container cap 90 can slide from the cap placing bodies 51 to the cap pushing member 52, and the cap pushing member 52 can separate a single container cap 90 from other container caps 90, so that a single container cap 90 can be clamped by the cap screwing member 53, and then the container cap 90 is screwed to the container mouth 801 of the container 80 by the cap screwing member 53.

[0063] As an example, the cap placing body 51 is implemented as a conveyor belt. The fifth driving member 54 is implemented as a driving motor.

[0064] Preferably, the cover placing body 51 has a starting portion 511 and a tail portion 512, and a cover placing channel 5101 is formed between the starting portion 511 and the tail portion 512, and the cover placing channel 5101 is used to convey the container cover 90, so that the container cover 90 placed manually or mechanically on the starting portion 511 is driven to the tail portion 512 through the cover placing channel 5101.

[0065] Preferably, the number of the cover-pushing members 52 corresponds to the number of the cover-placing bodies 51, and each of the cover-pushing members 52 is movably mounted on the rear end portion 512 of one of the cover-placing bodies 51, and the moving direction of the cover-pushing members 52 is different from the extending direction of the cover-placing channel 5101. Each of the cover-pushing members 52 has a lower end portion 521 and a higher end portion 522, and each of the lower end portions 521 can accommodate one of the container covers 90. When the cover-pushing member 52 is not moved, a single container cover 90 slides from the rear end portion 512 of the cover-placing body 51 to the lower end portion 521, and after the cover-pushing member 52 moves, a single container cover 90 is separated. When the cover-pushing member 52 moves, the higher end portion 522 blocks the container cover 90 subsequently located on the rear end portion 512, and when the cover-pushing member 52 is reset, the higher end portion 522 is reset to allow the next container cover 90 to slide to the lower end portion 521 for the next round of pushing.

[0066] It is worth mentioning that the high end portion 522 is higher than the low end portion 521 , so when the container cover 90 moves, the high end portion 522 can block the container cover 90 to prevent the container cover 90 from continuing to slide down.

[0067] Preferably, the number of the screw-on capping members 53 is set to correspond to the number of the cap-placing bodies 51, and each screw-on capping member 53 corresponds to one of the cap-pushing members 52 and is movably arranged above the rotation path of the container 80. The screw-on capping member 53 has a clamping opening 5301, which can be enlarged or reduced. When the screw-on capping member 53 moves to the corresponding container cap 90 on the lower end 521, the clamping opening 5301 is enlarged to cover the container cap 90, and is clamped after being reduced, thereby driving the container cap 90 to move above the container 80, and then tightening the container cap 90 to the container 80.

[0068] It is understood by those skilled in the art that when the container 80 is rotated to below the cover screwing member 53, a single container cap 90 is separated by the cover pushing member 52, and the cover screwing member 53 clamps the separated single container cap 90 and moves it to the container mouth 801 of the container 80, and tightens the container cap 90 at the same time. At this time, the cover pushing member 52 is reset to make the next container cap 90 located on the cap placing body 51 slide to the cover pushing member 52. In this way, the next container cap 90 is further separated by the cover pushing member 52, and the cover screwing member 53 continues the next round of tightening operation, so that the cover screwing process is repeated.

[0069] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized.
