Description

Technology Field

[0001] The present invention relates to a squid eye removal device. More specifically, the present invention relates to a squid eye removal device having a clamp for extracting the eyes of a squid. Background Technology

[0002] The content described in this section merely provides background information regarding the present invention and does not constitute prior art.

[0003] Squid, which is widely used as a food ingredient, is supplied in a live state, or in a frozen, refrigerated, or dried state without processing, but is also supplied after being processed appropriately for use. As shown in FIG. 1, the squid (2) has organs such as a mantle (body: 2a), head (2b), tentacles (2c), neck (2d: a narrow part at the boundary between the mantle and the head), fins (2e: also called 'ears'), internal organs (2f), and eyes (2g).

[0004] Squid (2) is processed in various ways according to the intended use, such as processing the mantle (2a) to be cut, processing the eyes (2g) from the head (2b) to be removed, processing the internal organs (2f) from the mantle (2a) to be separated, processing the head (2b) to be cut, processing the mantle (2a) to be separated from the legs (2c), processing the fins (2e) from the mantle (2a) to be separated, and processing the mantle (2a) to be cut. Various devices for processing squid are widely developed in conjunction with this.

[0005] Generally, the processing of squid can be said to begin with the process of gutting the mantle, and the inventor has developed a 'squid gutting device' as described in Korean Patents No. 10-0713581, No. 10-1609044, No. 10-1767462, and No. 10-1863663.

[0006] Prior art related to the removal of eyes from squid includes: Korean Published Patent No. 10-2013-0117943, 'Device for removing squid eyeballs and mouths'; Korean Patent No. 10-1252788, 'Squid leg processing machine'; Korean Patent No. 10-0253163, 'Squid gutting device'; Korean Published Patent No. 10-2001-0100151, 'Squid processing machine'; Korean Published Patent No. 10-2004-0042124, 'Automatic squid gutting machine'; Korean Registered Utility Model No. 20-0152052, 'Squid gutting and internal organ removal device'; Korean Registered Utility Model No. 20-0303989, 'Internal organ removal device of automatic squid gutting machine'; and Korean Registered Utility Model No. 20-0303990, 'Automatic squid gutting machine' There are devices such as the 'squid eye removal device' for the slaughterhouse.

[0007] However, these conventional squid eye removal devices had shortcomings, such as unsatisfactory working speed for removing eyes per unit of time, frequent failures in removing eyes completely requiring additional manual processing by the operator, and excessive damage to the squid tissue adjacent to the eyes during the eye extraction process, which lowered the marketability of the squid. The problem to be solved

[0008] The present invention is based on the aforementioned necessity, and the squid eye removal device of the present invention can remove eyes from a squid more quickly and reliably.

[0009] The problems that the present invention aims to solve are not limited to those mentioned above, and other unmentioned problems will be clearly understood by a person skilled in the art from the description below. means of solving the problem

[0011] According to one embodiment of the present invention, a squid eye removal device is provided, characterized by comprising: a tray having a support plate on which a squid is placed, and a fixing member formed on the leading edge of the support plate and into which the neck portion between the mantle and head of the squid is inserted to fix the squid on the support plate; and an eye extraction device having a clamp for picking up and extracting the squid eye placed on the tray. Effects of the invention

[0016] Hereinafter, some embodiments of the present invention will be described in detail with reference to the exemplary drawings. It should be noted that in assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the present invention, if it is determined that a detailed description of related known components or functions could obscure the essence of the invention, such detailed description is omitted.

[0017] In describing the components of an embodiment according to the present invention, symbols such as first, second, i), ii), a), b), etc., may be used. These symbols are intended only to distinguish the component from other components, and the essence, order, or sequence of the component is not limited by the symbols. When a part in the specification is described as 'comprising' or 'having' a component, this means that, unless explicitly stated otherwise, it does not exclude other components but may include additional components.

[0018] The squid eye (2g) removal device according to the present invention, illustrated exemplarily in FIGS. 1 to 8, is a device for extracting and removing the eye (2g) from the head (2b) of the squid (2) illustrated in FIG. 1. For example, it is a device that can be applied to the processing of removing the eye (2g) from the head (2b) of the squid (2) by installing it downstream of a slaughtering device (e.g., a slaughtering device according to the present inventor’s patent No. 10-1767462, etc.) that slaughters the mantle (2a) of the squid (2) being transported with the legs (2c) leading from the leg (2c) to the fin (2e). Conversely, the squid eye (2g) removal device according to the present invention may also be applied to the processing of removing the eye (2g) before slaughtering the squid (2) by installing it upstream of the slaughtering device.

[0019] The squid eye (2g) removal device according to the present invention can be applied independently without being connected to the above-mentioned squid cutting device, or can be applied in conjunction with other squid processing devices other than the squid cutting device, and can be applied in various ways depending on the situation.

[0020] The squid eye (2g) removal device according to the present invention can be installed together with a conveyor (10) on a stand (3: frame) formed for easy operation, and basically includes all or part of a conveyor (10), a tray (20), a restraining mechanism (30), and an eye extraction mechanism (40). The conveyor (10) is a conveying mechanism that transports a squid (2) to a processing location for removing eyes. The conveyor (10) is not limited to any form and can be applied as long as it is configured to transport the squid (2) to the location for extracting eyes (2g). As for the conveyor (10), for example, a circulating rotating chain type conveyor can be applied, which can install a plurality of trays (20) at regular intervals and move the installed trays (20) from upstream to downstream at a constant speed, and a conventional conveyor widely applied in automated machinery can be appropriately applied to suit the present invention. The above tray (20) is a plate-shaped member for setting the squid (2) in a state suitable for removing the eyes (2g), and can be installed on a conveyor (10) to be transported by, for example, a conveyor (10), as exemplarily illustrated in FIGS. 2 and 3.

[0021] While it is not excluded to apply only one tray (20) to the conveyor (10), multiple trays (20) may be installed at regular intervals to improve productivity through continuous operation. When multiple trays (20) are applied to a single conveyor (10), as the conveyor (10) rotates, the trays (20) pass through the position of the snow removal mechanism (40) at a constant speed and time interval, thereby continuously removing snow, which is desirable as it can increase work productivity.

[0022] The tray (20) includes a base plate (21) and a fixing member (22). The base plate (21) is a plate-shaped member that supports the squid (2) from below by placing the squid (2) on it, and, for example, a rectangular plastic synthetic resin plate may be used. To prevent the squid (2) set on the base plate (21) from unintentionally sliding or moving, the base plate (21) may be made of a material with high surface friction resistance, have a non-slip treatment on its surface, or have a non-slip uneven pattern formed thereon. The squid (2) may be set on the base plate (21), for example, such that the mantle (2a) and head (2b) are placed on the base plate (21) and the legs (2c) hang down below the tip of the base plate. That is, in the case of the illustrated specific example, the squid (2) set on the base plate (21) has its mantle (2a) and head (2b) placed on the base plate (21), while its legs (2c) are not placed on the base plate (21) and hang down naturally due to its own weight, and is transported from upstream to downstream along the conveyor (10) with the legs (2c) leading, together with the tray (20).

[0023] The above fixing member (22) is a member that fixes the squid (2) set on the base plate (21) so that the squid does not easily move out of place unintentionally. The fixing member (22) is formed on the front end of the base plate (21), and the narrow neck portion (2d) between the mantle (2a) and the head (2b) of the squid (2) is inserted into the fixing member (22), so that the squid (2) does not easily move out of place on the base plate (21). Therefore, the fixing member (22) is not particularly limited as long as it is configured to restrain the neck portion (2d) of the squid (2) so that the squid (2) set on the base plate (21) does not unintentionally move out of place.

[0024] The fixing member (22) of the illustrated embodiment is an example in which a pair of fixing pins (22a) are formed protruding upward at a certain distance from the front end of the base plate (21) and spaced apart from the rear end. In the illustrated embodiment in which the fixing pins (22a) are applied, if the gap between the fixing pins is wide, it is advantageous for inserting the neck (2d) between them, but if it is too wide, the small-sized squid may move unintentionally. Conversely, if the gap between the fixing pins is narrow, the inserted neck is well fixed to the fixing pins (22a), but if it is too narrow, the insertion of the neck between the fixing pins may fail. Therefore, the gap between the two fixing pins (22a) can be appropriately set to match the size of the squid being processed. In addition, a plurality of trays (20) equipped with fixing pins (22a) of different specifications may be provided, and a tray (20) equipped with a fixing pin (22a) that fits the size of the squid (2) to be processed may be selected and assembled on a conveyor (10) for use. The fixing pin (22a) may be formed in a roughly L-shape, with a vertical section (22b) extending vertically at the bottom and a horizontal section (22c) bent horizontally from the vertical section (22b) toward the tip at the top.

[0025] According to the tray (20) of the exemplary embodiment, the squid (2) is set on the base plate (21) with the neck (2d) fixed by the fixing member (22), so that the squid (2) does not easily move out of place, and the legs (2c) are naturally hanging down below the tip of the base plate (21), while the head (2b) is placed on the base plate (21) in front of the fixing member (22) and the mantle (2a) is placed on the base plate (21) in the rear of the fixing member (22), thereby minimizing the disruption of the eye removal process caused by the legs (2c) being scattered or the unintended damage to parts of the legs during the eye removal process, which reduces the marketability of the squid.

[0026] At the tip of the base plate (21), a recessed seating portion (23) can be formed inwardly between the fixed member (22). The seating portion (23) acts to keep the legs (2c) hanging down from the left and right from scattering. With this seating portion (23), interference with the snow removal process or a decrease in marketability caused by leg cutting, which can be caused by 'legs being scattered and parts of the legs being unintentionally placed on the base,' can be further minimized.

[0027] The tray (20) may include a fastener (24) for connecting the base plate (21) to the conveyor (10). That is, the fasteners (24) are installed parallel to each other at regular intervals, for example, at two locations on the lower surface of the base plate (21), and by connecting both ends of each fastener (24) to the conveyor (10), the tray (20) can be transferred from upstream to downstream along with the rotation of the conveyor (10) while connected to the conveyor (10).

[0028] The restraint mechanism (30) may include a longitudinal pressure mechanism (31) and a transverse pressure mechanism (32). The longitudinal pressure mechanism (31) restrains the head (2b) of the squid (2) so that the eye (2g), which is positioned in front of the fixing member (22) by inserting the neck portion (2d) into the fixing member (22) as exemplarily illustrated in FIGS. 2 and 3, is positioned without vertical movement relative to the tray (20). The longitudinal pressure mechanism (31) works in cooperation with the fixing member (22) to restrain the head (2b) of the squid (2) more firmly. With the neck portion (2d) inserted into the fixing member (22), the eye (2g) located on the head (2b) of the squid (2) is positioned directly in front of the fixing member (22). The longitudinal pressure mechanism (31) restrains the head (2b) of the squid (2) so that the position of the eye (2g) is accurately positioned on the driving path of the eye extraction mechanism (40) described later. As a result, the eye (2g) is reliably extracted without failure by the eye extraction mechanism (40) as described later. In the exemplary embodiment where a conveyor is applied, the tray (20) on which the squid (2) is set is in a 'waiting state' where the longitudinal pressure mechanism (31) does not pressurize the head (2b) before the tray (20) on which the squid (2) is set approaches the eye removal device of the present invention.

[0029] The lateral pressure mechanism (32) is installed at the rear of the head so as to be displaceable to the left and right, and restrains the head to the left and right so that the left and right positions of the eyes are positioned at the position of the pincers (41). The lateral pressure mechanism (32) may include a pair of plate-shaped members (32b) each positioned on both sides of the head. A squid on the tray (20) may be placed at the position where the pair of plate-shaped members (32b) face each other. A squid may be placed between the lower parts of the pair of plate-shaped members (32b), and a gear for displacement of the plate-shaped members (32b) may be coupled to the upper part of the plate-shaped members (32b). A gear may be coupled to each plate-shaped member (32b), and each gear may be installed to rotate by meshing with each other. The pair of gears mesh and rotate in opposite directions. Accordingly, the lower ends of the plate-shaped members (32b) may move further apart from each other or closer together. Before the squid approaches the eye extraction device (40), a pair of plate-shaped members (32b) are positioned in a standby position that is spaced apart from each other. When the squid enters the eye extraction device (40), the pair of plate-shaped members (32b) move closer together and restrain the left and right sides of the squid. Accordingly, it is possible to prevent the left and right positions of the squid from changing during the process of extracting the squid's eyes (2g).

[0030] In describing the illustrated squid eye removal device, up and down refers to the direction of arrow A in FIG. 2, and forward and backward refers to the direction of arrow B.

[0031] The longitudinal pressure mechanism (31) applied to the present invention is not particularly limited as long as it is a mechanism capable of restraining the head (2b) so that the position of the eye (2g) is accurately located on the driving path of the eye extraction mechanism (40). Here, the fixing member (22) may be an L-shaped fixing pin (22a) having the aforementioned vertical portion (22b) and horizontal portion. In the exemplary embodiment, the longitudinal pressure mechanism (31) may include, for example, a plate-shaped longitudinal pressure piece (31a) that is inserted between the base plate (21) and the head (2b) and installed to be displaceable up and down. The longitudinal pressure piece (31a) restrains the head (2b) by pushing it upward, thereby ensuring that the vertical position of the eye (2g) is accurately located on the driving path of the clamp (41) without movement.

[0032] In the illustrated embodiment, the neck portion (2d) of the squid (2) is inserted between the fixing pins (22a), so the left-right movement of the head (2b) is constrained by the vertical portions (22b) on both sides of the fixing pins (22a). When the tray (20) approaches the eye extraction mechanism (40) of the eye removal device according to the present invention, the longitudinal pressure piece (31a) pushes the head (2b) upward, thereby constraining the head (2b) by being squeezed between the longitudinal pressure piece (31a) and the horizontal portion of the fixing pins (22a), and here the upper and lower position of the eye (2g) corresponds to the upper and lower position of the clamp (41). In addition, the lateral pressure mechanism (32) holds both sides of the head (2b), thereby more reliably preventing the head (2b) of the squid (2) from unintentionally moving left and right.

[0033] The eye extraction mechanism (40) includes all or part of a clamp (41), a displacement mechanism (42a), an opening / closing mechanism (42b), a rotation mechanism (42c), a position sensor (60), and a controller (70). The clamp (41) can grasp or release the eye (2g) of the squid (2) depending on the opening / closing. The eye extraction mechanism (40) may have a pair of clamps (41) corresponding to each of the pair of eyes (2g) of the squid (2). The pair of clamps (41) may be driven to remove the squid eye (2g) on ​​the corresponding side. The clamps (41) may be placed on the side of the squid (2) placed on the tray (20). Specifically, a clamp (41) for removing the right eye (2g) can be placed on the right side of the squid (2), and a clamp (41) for removing the left eye (2g) can be placed on the left side of the squid (2).

[0034] Referring to FIG. 4(a), the displacement mechanism (42a) may be configured to move the claw (41) in a linear motion toward or toward the squid (2). A pair of claws (41), each positioned on the left and right sides of the squid (2), may advance or retract toward the squid (2) by means of the displacement mechanism (42a). The configuration of the displacement mechanism (42a) is not particularly limited as long as it is intended to move the claw (41) in a linear motion. The displacement mechanism (42a) may include, for example, an air cylinder and piston or a gear and a cam to convert the rotational motion of a motor into linear motion. By means of the displacement mechanism (42a), the claw (41) may advance toward the squid's eye (2g) and be inserted into the squid's eyelid (2h).

[0035] Referring to FIG. 4(b), the opening / closing mechanism (42b) drives the clamp (41) to open or close the mouth of the clamp (41). The clamp (41) may be installed such that a pair of clamp (41) pieces are arranged vertically. The clamp (41) opens or closes as the squid-side ends of the pair of clamp (41) pieces move further apart or closer together. The opening / closing mechanism (42b) may include a rotating member configured to rotate each clamp (41) piece. However, the configuration of the opening / closing mechanism (42b) is not particularly limited as long as it is configured to open and close the clamp (41). By means of the opening / closing mechanism (42b), the clamp (41) can open and close the eyelids (2h) of the squid or grasp the eyes (2g) of the squid.

[0036] Referring to FIG. 4 (c), the rotating mechanism (42c) is configured to rotate the tongs (41) about the longitudinal axis of rotation of the tongs (41). By rotating the tongs (41) while the tongs (41) is gripping the squid eye (2g), the squid eye (2g) can be reliably extracted from the squid head (2b).

[0037] Referring to FIG. 5, the position sensor (60) recognizes the position of the squid eye (2g). The position sensor (60) may be an image sensor that analyzes pixels of input image information to derive the position of the squid eye (2g). However, the type of position sensor (60) is not particularly limited as long as it recognizes the position of the squid eye (2g). The position sensor (60) can transmit information about the position of the squid eye (2g) to the controller (70).

[0038] In addition, the position sensor (60) may be configured to recognize the position of the tray (20). Using the position information of the tray (20) obtained by the position sensor (60), the controller (70) may drive the lateral pressure mechanism (32) described above. Alternatively, referring again to FIGS. 2 and 3, the driving of the restraining mechanism is not achieved by the coordinated operation of the position sensor (60) and the controller (70), but by a physical structure. Specifically, an air cylinder (32a) is installed on the plate-shaped member (32b) so that a pair of plate-shaped members (32b) become close to or apart from each other by the extensional movement of the air cylinder (32a), and the timing of supplying air to the ports of the air cylinder (32a) can be linked to the position of the support plate (21) being transported from upstream to downstream by the conveyor (10). For example, a timing sprocket (not shown) that rotates in engagement with a conveyor (10) may be installed, and a timing cam (55a) that rotates integrally with the timing sprocket may be installed, wherein the contour of the timing cam (55a) is designed to match the time when the head of a squid enters and passes through the position of the eye extraction mechanism (40), and a limit switch (55b) for opening and closing a (solenoid) valve (55c) that controls the air supplied to the air cylinder (32a) may be installed adjacent to the timing cam (55a).

[0039] Referring to FIG. 6(a), before the tray (20) enters the position of the eye extraction mechanism (40), the controller (70) controls the driving mechanism (40) so that the clamp (41) is positioned in a standby position separated from the transport path. The controller (70) can control the opening / closing mechanism (42b) so that the clamp (41) is in a closed state in the standby position. Here, the lateral pressure mechanism (32) may be separated from the squid (2) transport path by the mechanism described above. Additionally, the longitudinal pressure mechanism (31) may be in a standby state that does not press the squid upward.

[0040] Referring to FIG. 6(b), thereafter, when the tray (20) enters the position of the eye extraction mechanism (40), the controller (70) controls the driving mechanism (40) to advance the clamp (41) to the position of the squid's eye (2g) recognized by the position sensor (60) in order to insert the clamp (41) into the squid's eyelid (2h). Here, the clamp (41) is inserted into the squid's eyelid (2h) in a closed state. Here, so that the squid's eye (2g) is accurately positioned at the position of the clamp (41), the longitudinal pressure mechanism (31) pushes the squid's head (2b) upward, and the lateral pressure mechanism (32) restrains the left and right sides of the squid (2). Thus, the squid's eye (2g) is accurately positioned in the direction facing the claw (41), and the squid's head (2b) is prevented from moving unintentionally during the process of extracting the eye (2g).

[0041] Referring to Fig. 6(c), the controller (70) controls the driving mechanism (40) so that the clamp (41) opens to open the squid's eyelid (2h). Then, referring to Fig. 6(d), the controller (70) controls the driving mechanism (40) so that the clamp (41) grasps the squid's eye (2g). By grasping the squid's eye (2g) while it is inserted into the squid's eyelid (2h), damage to the external tissue of the squid's eyelid (2h) can be minimized. Then, referring to Fig. 6(e), the clamp (41) is separated from the head (2b) to extract the grasped squid's eye (2g) from the head (2b). At the same time, in order to extract the squid eye (2g) more reliably, the controller (70) may control the rotation mechanism (42c) so that the clamp (41) rotates at a predetermined angle inside the squid's eyelid (2h).

[0042] Afterward, the controller (70) controls the driving mechanism (40) so that the clamp (41) returns to the standby position. Before the next tray (20) is supplied so that the squid eye is removed from the clamp (41) in the standby position, the controller (70) may open and close the clamp (41) once. Afterward, when the clamp (41) is closed again and a new tray (20) is supplied to the eye extraction mechanism (40), the process from (a) of FIG. 6 can be repeated. Accordingly, the eye removal device of the present invention can continuously remove the eyes (2g) of the squid (2), thus having a fast processing speed.

[0043] Although FIGS. 1 to 6 illustrate the tongs approaching or moving away from the squid's eyes in a direction perpendicular to the squid, the angle at which the tongs approach or move away from the squid is not limited to the vertical direction. For example, the tongs may be positioned so that the end of the tray on which the squid is placed is gathered inward, and may move at a predetermined angle that is not perpendicular to the squid to approach or move away from the squid's eyes.

[0044] The squid eye removal device according to the present invention may be constructed to operate when the tray (20) on which the squid (2) is set is stationary and not being transported, or it may be constructed to remove the eyes (2g) while the tray (20) on which the squid (2) is set is being transported from upstream to downstream along a conveyor so that productivity can be increased through continuous operation.

[0045] In the latter case, the squid eye removal device according to the present invention can be constructed to move from upstream to downstream at a speed corresponding to the transport speed of the tray (20) to remove eyes from the squid in the preceding tray (20), and after completing the removal of eyes for one tray (20), to move back to the original upstream position to remove eyes from the squid in the subsequent tray (20). The mechanisms required for the reciprocating movement of the squid eye removal device according to the present invention are not directly related to the features of the present invention, and since related prior art can be applied to the present invention, a detailed description thereof is omitted.

[0046] FIG. 7 is a perspective view showing a clamp, etc., according to a second embodiment of the squid eye removal device of the present invention.

[0047] FIG. 8 is a side view showing a clamp, etc., according to a second embodiment of the squid eye removal device of the present invention.

[0048] FIGS. 1 to 6 illustrate a clamp (41, see FIGS. 1 to 6) and the like according to a first embodiment. Hereinafter, a clamp (210, see FIGS. 7 and 8) and the like according to a second embodiment will be described with reference to FIGS. 7 and 8. The clamp (210) and the like according to the second embodiment can be applied to the squid eye removal device of the present invention in place of the clamp (41) and the like illustrated in FIGS. 1 to 6. In FIGS. 7 and 8, U indicates the upstream direction and D indicates the downstream direction.

[0049] Referring to FIGS. 7 and 8, a clamp (210) according to a second embodiment of the present disclosure comprises a lower gripping portion (212) and an upper gripping portion (211) positioned above the lower clamp (210). A squid eye (2g) is positioned between the lower gripping portion (212) and the upper gripping portion (211), and the lower gripping portion (212) and the upper gripping portion (211) can grip the squid eye (2g). Two clamps (210) may be provided on both the left and right sides so that each clamp extracts a different squid eye (2g).

[0050] A hollow may be formed in the portion where at least one of the upper gripping portion (211) and the lower gripping portion (212) is located. By having a hollow portion, the clamp (210) can operate to extrude the squid eye (2g) from the squid head (2b) beyond simply gripping the squid eye (2g). For example, as shown in FIG. 7, the upper gripping portion (211) and the lower gripping portion (212) may be formed in a U-shape, and the squid eye (2g) may be placed in the empty space of the ring formed by the U-shaped gripping portion.

[0051] The upper gripping part (211) and the lower gripping part (212) move relative to each other in a direction of approaching or separating, and can grip the squid eye (2g) or detach the squid eye (2g). The opening / closing mechanism may include a height adjustment piston (220) for adjusting the height of at least one of the upper gripping part (211) and the lower gripping part (212). The opening / closing mechanism according to the second embodiment has a height adjustment piston (220) for adjusting the height of the lower gripping part (212). The height direction position of the upper gripping part (211) is fixed, and the lower gripping part (212) moves up and down, allowing the squid eye (2g) between the upper gripping part (211) and the lower gripping part (212) to be extracted.

[0052] However, the driving method of the clamp (210) of the present invention is not limited to this embodiment. For example, the clamp (210) may be configured such that the height-direction position of the lower gripping part (212) is fixed and the upper gripping part (211) moves up and down to extract the squid eye (2g).

[0053] The displacement mechanism may be configured to displace the clamp (210) along the longitudinal direction of the clamp (210). The displacement mechanism may include a horizontal displacement control piston (230) configured to extend and shorten in the horizontal direction. The horizontal displacement control piston (230) may be directly or indirectly coupled to the clamp (210) to move the clamp (210) in the horizontal direction, thereby causing the squid clamp (210) to move closer to or further away from the squid eye (2g).

[0054] The height adjustment piston (220) and the horizontal displacement adjustment piston (230) can be connected in a mutually vertical direction. Additionally, a clamp (210) can be connected to the free end of the height adjustment piston (220). Since the horizontal displacement adjustment piston (230) is connected to the free end of the height adjustment piston (220), the horizontal displacement adjustment piston (230) and the clamp (210) can be displaced together as the free end of the horizontal displacement adjustment piston (230) is displaced in the horizontal direction.

[0055] Additionally, a clamp (210) can be attached to the free end of the height adjustment piston (220). Thus, the clamp (210) can move up and down together as the free end of the height adjustment piston (220) moves up and down, and can move horizontally together as the free end of the horizontal displacement adjustment piston (230) moves horizontally.

[0056] A pair of horizontal displacement control pistons (230) are provided, and one horizontal displacement control piston (230) can be connected to each clamp (210). A pair of height control pistons (220) are provided, and one height control piston (220) can be connected to each clamp (210).

[0057] Additionally, the horizontal displacement control piston (230) may be installed to be rotatable about an axis in the height direction. Depending on the rotation angle of the pair of horizontal displacement control pistons (230), the angle at which the ends of the pair of clamps (210) face each other may vary.

[0058] A mounting base (250) may be fixedly installed at a location adjacent to the conveyor (10), and a horizontal displacement control piston (230) may be installed on the mounting base (250) so as to be rotatable about the height direction as an axis. For example, a first connecting member (260) may be fixedly coupled to the lower side of the mounting base (250), and a horizontal displacement control piston (230) may be rotatably coupled to the first connecting member (260).

[0059] In the second embodiment, a lateral pressure piece (240) may be provided as a restraining mechanism. The lateral pressure piece (240) restrains the head (2b) by pushing it laterally backward, thereby ensuring that the front and rear positions of the eye (2g) are accurately positioned at the position of the clamp (210) without movement. A second connecting member (270) may be fixedly coupled to the lower side of the mounting base (250), and the lateral pressure piece (240) may be rotatably coupled to the second connecting member (270).
