Description

Apparatus for Grappling Seafood The present invention relates to a fish and shellfish gripping device, and more specifically, to a fish and shellfish gripping device capable of safely gripping fish and shellfish without damaging them. Generally, the processing of seafood, such as fish, shellfish, and mollusks, relies entirely on manual labor for various stages of the manufacturing process, including pretreatment, sorting, processing, and packaging, because automation is difficult due to the flexible and irregular nature of the seafood. However, as the sustainability of the workforce and processed seafood products is gradually declining due to factors such as the decrease and aging of the fishing population, active technological development is currently underway to automate seafood processing using robots and IoT technologies to address these issues. Among these, the development of a shellfish gripping device capable of safely gripping shellfish and safely transferring them to subsequent processes is essential. However, existing shellfish gripping devices had limitations in that they could not stably grip shellfish without damage, as gripping was achieved by lifting both sides of the shellfish, causing them to easily break or slip and fall out. FIG. 1 is a perspective view of the use state of a fish and shellfish grasping device according to the present invention. FIG. 2 is an exploded perspective view of a fish and shellfish holding device according to the present invention. FIG. 3 is an exploded perspective view of a gripper constituting the present invention. FIG. 4 is a cross-sectional view along line IV-IV of FIG. 1, showing the operating state of the gripper. Figure 5 is a cross-sectional view along V-V of Figure 1. The features and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments based on the accompanying drawings. Prior to this, terms and words used in this specification and claims must be interpreted in a meaning and concept consistent with the technical spirit of the invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention. Furthermore, the terms and words used in this specification and claims are used merely to describe specific embodiments and are not intended to limit the invention. For example, a singular expression includes a plural expression unless the context clearly indicates otherwise. Furthermore, terms such as "include," "equip," or "have" are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Furthermore, when a part such as a layer, membrane, region, or plate is said to be "above" another part, this includes not only the case where it is "directly above" the other part, but also the case where there is another part in between. Conversely, when a part such as a layer, membrane, region, or plate is said to be "below" another part, this includes not only the case where it is "directly below" the other part, but also the case where there is another part in between. In addition, terms including ordinal numbers, such as "first," "second," etc., used in this specification may be used to describe various components, but said components are not limited by said terms, and said terms are used solely for the purpose of distinguishing one component from another. Hereinafter, in describing an embodiment of the present invention in detail with reference to the drawings, the same reference numerals are used for identical components, and for clarity, only the different parts are described primarily to avoid duplication as much as possible. The shellfish grasping device of the present invention can be applied to a grasping robot that grasps shellfish moving sequentially along a conveyor and moves the grasped shellfish to a sorting pallet. In addition, the objects to be grasped may include, for example, fish, shellfish, and mollusks, and it is particularly advantageous for grasping oyster meat from which the shell has been removed among shellfish. As illustrated in FIGS. 1 to 5, the fish and shellfish gripping device (100) of the present invention comprises a body part (110), a pair of grippers (120), a driving unit (130) that provides reciprocating movement force to the grippers (120), and a detachment prevention barrier (140) mounted on the grippers (120) to prevent the gripped fish and shellfish from detaching from the grippers (120). The above body part (110) is fixed to the gripping robot (R), and a gripper (120) is installed at the bottom. A pair of the above-mentioned grippers (120) are installed so that they can move back and forth a certain distance in the left and right directio
