[0035] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application will be described clearly and completely below in combination with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0036] In this document, "illustrative" means "serving as an example, instance, or illustration" and should not necessarily be construed as "preferred" or "advantageous" over other embodiments.

[0037] To keep the drawings concise, only the parts relevant to this application are shown schematically in each drawing, and they do not represent the actual structure of the product. In addition, to make the drawings concise and easy to understand, in some drawings, only one of the components with the same structure or function is shown schematically, or only one of them is labeled.

[0038] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0039] Figure 1 An exploded view illustrating an illustrative embodiment of the movable hook assembly of the filling machine gripper. Figure 2 Used to explain Figure 1 The diagram shows the structure of the movable hook assembly of the filling machine gripper.

[0040] Figure 1 and Figure 2 A pair of filling machine grippers 30 are shown for use on a filling machine. The pair of grippers 30 are movable relative to each other along the gripping direction X indicated by the arrow in the figure. Those skilled in the art will understand that, depending on actual needs, only the left gripper 30 may move, or only the right gripper 30 may move, or both grippers 30 may move simultaneously, as long as the pair of grippers 30 can move relative to each other.

[0041] Each of the pair of filling machine grippers 30 is equipped with a sealing device 40 (the sealing device on the left gripper 30 in the figure is obscured) for heat sealing and other operations on the packaging. When the pair of filling machine grippers 30 move relative to each other in the clamping direction to a clamping position, in order to enable the sealing devices 40 on the pair of filling machine grippers 30 to cooperate with each other to clamp the packaging, a set of hook components can be provided on each side of the sealing device 40 to help achieve a tight clamping state.

[0042] exist Figure 1 and Figure 2 In the pair of filling machine grippers 30 shown, the left filling machine gripper 30 is provided with fixed hooks 20 on both sides of the sealing device 40, and the right filling machine gripper 30 is provided with movable hook assemblies 10 on both sides of the sealing device 40. Each movable hook assembly 10 includes a movable hook 12 and a fixing member 14. The fixed hooks 20 and movable hooks 12 are arranged opposite to each other. When the pair of filling machine grippers 30 move relative to each other to the clamping position along the clamping direction, the fixed hooks 20 and movable hooks 12 can engage with each other to maintain the clamping state.

[0043] The right-side filling machine gripper 30 is also equipped with a drive member 32 capable of reciprocating along the gripping direction on its gripping side, and a movable hook 12 is rotatably mounted on the drive member 32. In the embodiment shown in the figure, the movable hook 12 can be connected to the drive member 32 via a connecting shaft 126, and can rotate relative to the drive member 32 about the connecting shaft 126 as a rotation axis when the drive member 32 moves along the gripping direction. The movable hook 12 is integrally formed and has a hook portion 122 and a movable connecting portion 124, both of which rotate together with the movable hook 12 about the rotation axis.

[0044] The fixing member 14 is fixedly disposed on the clamping side of the filling machine gripper 30, and the movable connecting part 124 of the movable hook 12 can be connected to the fixing member 14. During the reciprocating movement of the driving member 32 relative to the fixing member 14 in the clamping direction, the moving driving member 32 drives the movable hook 12 to move. Due to the connection relationship between the movable connecting part 124 of the movable hook 12 and the fixing member 14, the movable hook 12 can only rotate around the connection point between the movable connecting part 124 and the fixing member 14 and cannot move. As a result, the hook part 122 of the movable hook 12 rotates, so that the hook part 122 can reach the engagement position with the fixed hook 20 and can also disengage from the engagement position. During this process, the movable hook 12 can also rotate around the connecting shaft 126 under the action of the driving member 32. The rotation axis around which the movable hook 12 rotates around the connection point between the movable connecting part 124 and the fixing member 14 is parallel to the connecting shaft 126.

[0045] For detailed work procedures, please refer to [link / reference]. Figures 3 to 5 .exist Figures 3 to 5 In the illustrated embodiment, the movable connecting portion 124 of the movable hook 12 has two opposing abutment walls 125, and a connecting groove is defined between the two opposing abutment walls 125. The fixing member 14 is an abutment shaft received in the connecting groove and contacts the two abutment walls. Depending on the design requirements, the movable connecting portion 124 may also define a connecting elongated hole to receive the fixing member 14.

[0046] like Figure 3 As shown, at this time, the two filling machine grippers 30 have not yet reached their gripping positions, and the hook portion 122 of the movable hook 12 has not yet reached its engaging position, causing the two filling machine grippers 30 to move relative to each other along the gripping direction X indicated by the arrow in the figure until they reach their gripping positions. Figure 4 The clamping position is shown.

[0047] like Figure 4As shown, at this time, the control drive 32 moves to the right side of the filling machine gripper 30, as indicated by the arrow. The drive 32 will pull the movable hook 12 to move synchronously. Since the fixed part 14 acts as the abutment shaft against the abutment wall 125 of the movable connecting part 124, the movable hook 12 will rotate around the fixed part 14 as the fulcrum and rotate counterclockwise around the connecting shaft 126, so that the hook part 122 rotates towards its fastening position until the fastening action with the fixed hook 20 is completed.

[0048] like Figure 5 As shown, at this time, the hook portion 122 of the movable hook 12 and the fixed hook 20 are engaged with each other, fixing and tightening the relative position between the pair of filling machine grippers 30. In this state, the subsequent heat sealing process can be completed by the sealing device 40. If it is necessary to release the engagement, the control drive 32 moves to the left, i.e., toward the left side of the filling machine gripper 30, as indicated by the arrow. The drive 32 will push the movable hook 12 to move synchronously. Since the fixed member 14 acts as abutting shaft against the abutting wall 125 of the movable connecting part 124, the movable hook 12 will rotate around the fixed member 14 as a fulcrum, and at the same time rotate clockwise around the connecting shaft 126, causing the hook portion 122 to disengage from its engagement position and return to the original position. Figure 4 The state shown.

[0049] The aforementioned movable hook assembly has a simple structure and stable and reliable fastening action. It replaces the elastic component with the structural cooperation between the fixed part and the movable connecting part, thus avoiding equipment failure caused by damage to the elastic component.

[0050] exist Figures 3 to 5 In the structural fit between the movable connecting part 124 and the fixing member 14 shown, the fixing member 14, which serves as the abutment shaft, can be either a completely fixed shaft or a rotatable shaft structure. Furthermore, although the abutment shaft shown in the figure is cylindrical, those skilled in the art will understand that, depending on design requirements, the abutment shaft may not be cylindrical, such as a hexagonal shaft. To reduce sliding friction, rolling elements, such as rollers or bearings, can also be fitted onto the abutment shaft.

[0051] Those skilled in the art will understand that, depending on the design requirements, the movable connection 124 and the fastener 14 may also adopt other structural mating relationships.

[0052] Please see Figure 6 ,exist Figure 6 In the illustrated embodiment, the fastener 14 has two spaced-apart fastening portions 142, and the movable connecting portion 124 can extend between the two fastening portions 142 and contact the two fastening portions. Its clamping and fastening process is similar to... Figures 3 to 5The similarities shown will not be repeated. The two fixed parts 142 are abutment posts. Similarly, the abutment posts can be either completely fixed structures or rotatable shaft structures. Furthermore, although the abutment shaft shown in the figure is cylindrical, those skilled in the art will understand that, depending on design requirements, the abutment posts may not be cylindrical, such as hexagonal posts. To reduce sliding friction, rolling elements, such as rollers or bearings, can also be fitted onto the abutment posts.

[0053] Figure 1 and Figure 2 The illustrated embodiment also provides a gripper device for a filling machine, comprising a pair of filling machine grippers 30 capable of relative movement along the gripping direction X. Of the pair of grippers 30, the left gripper 30 has a fixed hook 20 on its gripping side, and the right gripper 30 has a driving member 32 capable of reciprocating along the gripping direction and the aforementioned movable hook assembly 10 on its gripping side. In the movable hook assembly, a fixed member 14 is fixedly disposed on the gripping side of the filling machine gripper, and a movable hook 12 is rotatably disposed on the driving member 32 about a rotation axis. In the gripping position of the pair of grippers 30, when the driving member 32 reciprocates along the gripping direction, the movable hook 12 can be driven to rotate around the connection point between the movable connecting part 124 and the fixed member 14, thereby causing the hook part 122 to reach an engaged position with the fixed hook 20 or disengage from the engaged position.

[0054] This application also provides a filling machine having the above-described gripper device and a sealing device disposed on the gripper device for heat sealing the packaging.

[0055] The above description is merely a specific embodiment of this application. Under the teachings of this application, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of this application, and the scope of protection of this application should be determined by the scope of the claims.
