Description

Technical Field

[0001] This application relates to the field of bottle handling technology, and more particularly to airbag-type bottle gripping devices and case packers. Background Technology

[0002] After filling, the bottles are often packed into boxes using a case packer. A case packer consists of a robotic arm and grippers mounted on the robotic arm. The grippers include multiple bottle gripping devices, such as airbag grippers. When the case packer is in use, the robotic arm moves the grippers above the bottles to be packed, the grippers grab the bottles, and then the robotic arm moves the grippers above the boxes, where the grippers place the bottles into the boxes.

[0003] In existing technology, some bottle caps are aluminum-plastic caps, which consist of an aluminum part and a plastic part. The aluminum part forms the side wall of the cap, and the plastic part forms the top wall. When the airbag-type bottle gripping device grips the aluminum-plastic cap, the inflated airbag squeezes the plastic part, causing it to detach. Utility Model Content

[0004] This application provides an airbag-type bottle gripping device and a case packing machine to solve the problem of the plastic part of the aluminum-plastic cap falling off due to the pressure of the airbag.

[0005] To achieve the above objectives, in a first aspect, this application provides an airbag-type bottle gripping device, comprising:

[0006] A housing having a lower opening and an accommodating space communicating with the lower opening;

[0007] An airbag is disposed within the accommodating space. The lower end of the airbag is connected to the inner wall of the outer shell, dividing the accommodating space into a gas chamber formed between the airbag and the outer shell, and a bottle-gripping space formed between the airbag and the lower opening.

[0008] A venting component, disposed within the housing, having a gas passage, one end of which is connected to a gas source, and the other end of which communicates with the gas chamber; and

[0009] A bottle cap cover is disposed within the bottle gripping space and is fixedly connected to the ventilation component through the airbag. The bottle cap cover has a bottle cap receiving groove on the side facing the downward opening.

[0010] Secondly, this application provides a case packer, including the airbag-type bottle gripper as described in the first aspect.

[0011] Compared with the prior art, this application includes at least the following beneficial effects:

[0012] In this application's airbag-type bottle gripping device, the plastic portion of the aluminum-plastic cap is located within the cap receiving groove of the cap cover during bottle gripping. Therefore, when the airbag inflates, compression occurs between the airbag and the cap cover, avoiding the compression between the airbag and the plastic portion of the aluminum-plastic cap as in the prior art. Consequently, the airbag-type bottle gripping device of this application does not cause the plastic portion of the aluminum-plastic cap to detach during bottle gripping, reducing product scrap rates.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] like Figure 1 As shown, the airbag-type bottle gripping device provided in this application includes a housing 1, an airbag 3, a ventilation component 2, and a bottle cap cover 7.

[0029] like Figure 1 As shown, the outer casing 1 has a lower opening and an accommodating space communicating with the lower opening. Specifically, the outer casing 1 may include a top wall 1.3 and a side wall 1.4. The upper end of the side wall 1.4 is connected to the top wall 1.3, and the lower end of the side wall 1.4 extends downward, forming the lower opening. The side wall 1.4 and the top wall 1.3 together enclose the accommodating space. The diameter of the lower opening is larger than the diameter of the bottle cap (using an aluminum-plastic cap 4 as an example in this embodiment) and the diameter of the bottle neck, so that the bottle cap and the bottle neck can enter the accommodating space.

[0030] like Figure 1 As shown, the airbag 3 is disposed within the accommodating space. The lower end of the airbag 3 is connected to the inner wall of the outer shell 1, dividing the accommodating space into a gas chamber formed between the airbag 3 and the outer shell 1, and a bottle-gripping space formed between the airbag 3 and the lower opening. Gas can be introduced into or discharged from the gas chamber. When gas is introduced into the gas chamber, the airbag 3 inflates and the bottle-gripping space contracts; when gas is discharged from the gas chamber, the airbag 3 contracts and the bottle-gripping space expands.

[0031] like Figure 1As shown, the venting component 2 is disposed on the outer casing 1, for example, the venting component 2 passes through a through hole in the top of the outer casing 1. The venting component 2 has a gas passage 2.1, one end of which is used to connect to a gas source (not shown), and the other end of the gas passage 2.1 communicates with a gas chamber. When it is necessary to inflate the airbag 3, the gas source can supply compressed air 6 to the gas chamber. The gas source can be an air tank.

[0032] like Figure 1 As shown, the bottle cap cover 7 is disposed within the bottle gripping space and is fixedly connected to the ventilation component 2 through the airbag 3. The side of the bottle cap cover 7 facing downward opening has a bottle cap receiving groove 7.1. When gripping a bottle, the bottle cap is received in the bottle cap receiving groove 7.1.

[0033] like Figure 2 As shown, when the airbag-type bottle gripping device of this application grips the bottle, the aluminum-plastic cap 4 and the neck of the bottle 5 extend into the bottle gripping space, and the plastic part 4.1 of the aluminum-plastic cap 4 is located in the cap receiving groove 7.1. The air source inflates the gas chamber through the gas channel 2.1, causing the airbag 3 to expand. The airbag 3 is squeezed between the bottle cap 7 and the aluminum part of the aluminum-plastic cap 4, thereby fixing the airbag 3 and the bottle 5 together.

[0034] like Figure 2 As shown, in this application, when the airbag-type bottle gripping device grips a bottle, the plastic part 4.1 of the aluminum-plastic cap 4 is located within the cap receiving groove 7.1 of the cap cover 7. Therefore, when the airbag 3 inflates, compression occurs between the airbag 3 and the cap cover 7, avoiding the compression between the airbag 3 and the plastic part 4.1 of the aluminum-plastic cap 4 as in the prior art. Thus, the airbag-type bottle gripping device of this application will not cause the plastic part 4.1 of the aluminum-plastic cap 4 to detach during bottle gripping, reducing the scrap rate of the bottle 5.

[0035] like Figure 1 As shown, the outer shell 1 includes an upper shell 1.1 and a lower shell 1.2. The lower shell 1.2 is connected to the lower end of the upper shell 1.1, and a mounting groove is formed between the upper shell 1.1 and the lower shell 1.2. The outward flange 3.1 of the airbag 3 extends into the mounting groove. Thus, the lower end of the airbag 3 is fixed to the inner wall of the outer shell 1.

[0036] like Figure 1 and Figure 3 As shown, the venting component 2 includes a shaft portion 2.2 and a stepped portion 2.3. The shaft portion 2.2 passes through the outer casing 1, for example, through a through hole in the top wall 1.3. The lower end of the shaft portion 2.2 is located in the accommodating space. The gas passage 2.1 is located in the shaft portion 2.2. The stepped portion 2.3 is connected to the lower end of the shaft portion 2.2 and is located within the bottle-gripping space. The upper end of the airbag 3 surrounds the outer periphery of the shaft portion 2.2 and abuts against the upper side surface of the stepped portion 2.3.

[0037] like Figure 3 As shown, the bottle cap receiving groove 7.1 includes a groove bottom surface 7.2 and a groove peripheral wall 7.3. The groove bottom surface 7.2 is used to abut against the upper surface of the bottle cap. The upper end of the groove peripheral wall 7.3 is connected to the groove bottom surface 7.2, and the lower end of the groove peripheral wall 7.3 extends downward, surrounding the outer periphery of the plastic part 4.1 of the aluminum-plastic cap 4. This prevents the airbag 3 from squeezing the plastic part 4.1 of the aluminum-plastic cap 4 after it inflates.

[0038] like Figure 3 As shown, the bottle cap 7 and the ventilation component 2 can be integrally molded.

[0039] This application also provides a case packer (not shown) that includes the above-described airbag-type bottle gripping device.

[0040] Although this application has been described in detail above with general descriptions, specific embodiments, and experiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this application fall within the scope of protection claimed in this application.
