Description

Technology Field

[0001] The present invention relates to a roll weight inversion device having a clamping structure. More specifically, the invention relates to a roll weight inversion device having a clamping structure capable of stably fixing a roll weight without damaging external raw materials and maintaining a stable operating state through a mechanical interlocking operating structure. Background Technology

[0002] Recently, various process equipment is being installed in manufacturing plants for the production processes of various products.

[0003] A wide variety of process equipment is being developed depending on the products being manufactured or the objects being handled, and reversal devices that reverse the placement direction of products on a manufacturing production line are also being developed in diverse ways depending on the type of product.

[0004] These inversion devices are primarily being developed for small or lightweight products, and development of such devices for large or heavy products is currently almost non-existent due to the difficulty of handling them.

[0005] Recently, roll-shaped heavy materials are widely used as raw materials for various products. Roll-shaped heavy materials generally consist of a core pipe in the center, with a disc used as a raw material wound around the outer surface of the core pipe.

[0006] In the production process of products using such rolled weights, a reversal device capable of reversing the placement direction of the rolled weights according to the manufacturing process is required.

[0007] Since rolled heavy loads are large and heavy, making them difficult to handle, it is challenging to implement a reversing mechanism for them using reversing structures applied to small products. In particular, because raw materials are wound around the outer surface of a core shaft, implementing a reversing mechanism is even more difficult as methods such as gripping and towing the roll from the outside can cause damage to the raw materials.

[0008] Therefore, the development of inversion devices for such rolled heavy loads is currently very limited, and research and development in this regard is urgently required. Prior art literature

[0011] The present invention provides a roll weight inversion device for receiving a roll-shaped weight having a core pipe in the center and reversing the arrangement direction of the received weight to transfer it to the outside, comprising: a base frame; a weight receiving module rotatably coupled to the base frame, receiving a weight in one direction from a separate transfer device, and pushing the weight out in the opposite direction of the receiving direction to transfer it to the outside; and a weight discharging module rotatably coupled to the base frame, receiving a weight discharged from the weight receiving module, and pushing the weight out in the opposite direction of the receiving direction to transfer it to the outside, wherein the weight receiving module and the weight discharging module are each provided with a clamp module formed to allow the core pipe of the weight to be inserted and operating to fix the inner surface of the core pipe by pressing it while the core pipe is inserted.

[0014] In addition, the clamping operating module is coupled to the insertion guide body so as to be linearly movable in the forward and backward directions along the longitudinal direction, and the clamping block can be protruded or retracted in conjunction with the linear movement of the clamping operating module.

[0015] Additionally, the clamping block has an inclined surface formed thereon, and the clamping operating module includes an operating rod coupled to the internal space of the insertion guide body so as to be linearly movable in the front-rear direction; and a pressure inclined block coupled to the outer circumference of the operating rod and having an inclined surface formed thereon to make surface contact with the inclined surface of the clamping block, and as the pressure inclined block moves linearly in the front-rear direction together with the operating rod while the pressure inclined block and the clamping block are in surface contact through the inclined surface, the clamping block can move along the inclined surface and protrude or be retracted.

[0016] In addition, the clamping operating module is formed such that the clamping block protrudes when the operating rod moves backward from a reference position and the clamping block retracts when the operating rod moves back to a reference position, and the operating rod can move backward a certain distance by the push transfer module.

[0017] Additionally, the clamping operating module may further include: a rod connecting body coupled to the rear end of the operating rod and moving together with the operating rod, with both ends exposed to the outside of the insertion guide body; a guide bar coupled to the base rotating body so as to be movable in the forward and backward directions and coupled through both ends of the rod connecting body to guide the movement path of the rod connecting body; and a first spring disposed between the rod connecting body and the base rotating body to apply an elastic force in the forward direction to the rod connecting body, and may be formed so that the rod connecting body moves backward by the push transfer module.

[0018] Additionally, the clamping operating module further includes a second spring positioned so that both ends are supported by a flange portion formed at the front end of the guide bar and by the rod connecting body, and the guide bar may be moved backward by the push transfer module, and the rod connecting body may be formed to move backward by the elastic force of the second spring in accordance with the backward movement of the guide bar.

Specific details for implementing the invention

[0021] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, 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.

[0022] FIG. 1 is a perspective view schematically illustrating the external appearance of a roll heavy object inversion device according to one embodiment of the present invention, FIG. 2a to 2d are drawings illustrating, in stages, the operating state of performing a roll heavy object inversion function for a roll heavy object inversion device according to one embodiment of the present invention, FIG. 3 is a perspective view schematically illustrating the external appearance of a heavy object receiving module and a heavy object shipping module according to one embodiment of the present invention, and FIG. 4 is a side view schematically illustrating the external appearance of a heavy object receiving module and a heavy object shipping module according to one embodiment of the present invention.

[0023] A roll weight inversion device according to one embodiment of the present invention is a device that receives a roll-shaped weight (30) having a core pipe (31) in the center and inverts the arrangement direction of the received weight (30) to transmit it to the outside, and comprises a base frame (10), a weight receiving module (20a), and a weight output module (20b).

[0024] The base frame (10) forms the support structure of the entire device and can be formed as a rectangular frame structure. A heavy object receiving module (20a) and a heavy object releasing module (20b) can be coupled to the upper part of the base frame (10).

[0025] The heavy material receiving module (20a) receives a heavy material (30) supplied in one direction from a separate transfer device (not shown) in a manner in which a core pipe (31) is inserted, and operates to deliver the supplied heavy material (30) to the outside by pushing it in the opposite direction to which the core pipe (31) is inserted.

[0026] The heavy object discharge module (20b) receives the heavy object (30) discharged from the heavy object receiving module (20a) in a manner in which the core pipe (31) is inserted, and operates to deliver the supplied heavy object (30) to the outside by pushing it in the opposite direction to which the core pipe (31) is inserted.

[0027] The heavy load receiving module (20a) and the heavy load releasing module (20b) are each rotatably coupled to the base frame (10) and rotated so as to be positioned opposite each other or parallel to each other.

[0028] These heavy load receiving modules (20a) and heavy load releasing modules (20b) can be formed to have the same shape and configuration as each other, and can be arranged symmetrically with respect to each other and spaced apart by a certain distance on the upper surface of the base frame (10) as shown in FIG. 1.

[0029] At this time, a rotation synchronization module (400) that synchronizes and rotates the heavy object receiving module (20a) and the heavy object releasing module (20b) so that the heavy object receiving module (20a) and the heavy object releasing module (20b) rotate simultaneously in directions facing each other or parallel to each other may be mounted on the base frame (10). The detailed structure of the rotation synchronization module (400) will be described later.

[0030] The heavy load receiving module (20a) includes a base rotating body (100), a clamping module (200), and a push transfer module (300).

[0031] The base rotating body (100) is configured to be rotatably coupled to the upper surface of the base frame (10) and may be configured to include a horizontal body part (110) rotatably coupled to the base frame (10) around a vertical axis and a vertical body part (120) extending vertically from one end of the horizontal body part (110). That is, the base rotating body (100) may be formed in an approximate "L" shape when viewed from the side.

[0032] The clamping module (200) is coupled to the base rotating body (100) and is formed to allow the core pipe (31) of the heavy object (30) to be inserted, and operates to fix the inner surface of the core pipe (31) by pressing it while the core pipe (31) is inserted. This clamping module (200) includes an insertion guide body (210) that is mounted in a hollow cylindrical shape and protrudes into the central area of ​​the vertical body part (120) of the base rotating body (100) so that the core pipe (31) of the heavy object (30) can be inserted. In addition to the insertion guide body (210), the clamping module (200) may further include a clamping block (220) and a clamping operation module (230), and the detailed structure of this clamping module (200) will be described later.

[0033] Meanwhile, a clamping module (200) capable of fixing a weight (30) while it is inserted may be coupled to the base rotating body (100), but instead of the entire configuration of the clamping module (200) being provided, it may be configured in a form where an insertion guide body (210) into which the weight (30) can be inserted is simply mounted.

[0034] The push transfer module (300) is coupled to the upper part of the vertical body portion (120) of the base rotating body (100) and operates to push out a weight (30) inserted into the insertion guide body (210). The detailed structure of the push transfer module (300) will be described later.

[0035] The insertion guide body (210) and the push transfer module (300) may be positioned to protrude horizontally from one of the two sides of the vertical body part (120) facing the horizontal body part (110). Accordingly, the heavy load receiving module (20a) may be formed in a roughly "T" shape when viewed from the side, as shown in FIG. 4.

[0036] Accordingly, when the heavy load receiving module (20a) rotates around a rotation axis coupled to the base frame (10), the radius of rotation (R), which is the distance from the center of rotation (C) to the outermost point, is relatively small, and thus the overall space efficiency can be improved.

[0037] That is, since the push transfer module (300) that pushes the heavy object (30) outward is arranged to extend forward rather than backward from the vertical body part (120), the radius of rotation (R) from the center of rotation (C) is reduced, and accordingly, even if the heavy object receiving module (20a) rotates during the process of reversing the heavy object (30), the radius of rotation (R) is small, so the rotation space is reduced during the rotation process, thereby improving the overall space efficiency of the process line.

[0038] In this heavy object receiving module (20a), a heavy object (30) is supplied from an external transfer device and inserted into an insertion guide body (210) while the push transfer module (300) is positioned at a reference position. The heavy object (30) is supplied in such a way that the core pipe (31) of the heavy object (30) is inserted into the insertion guide body (210). When the heavy object (30) is inserted, the heavy object receiving module (20a) pushes the heavy object (30) outward along the insertion guide body (210) through the push transfer module (300). The heavy object (30) discharged outward from the heavy object receiving module (20a) is inserted into the heavy object discharge module (20b).

[0039] The heavy object outgoing module (20b) has the same configuration as the heavy object receiving module (20a) as described above. That is, the heavy object outgoing module (20b) includes a base rotating body (100), a clamping module (200), and a push transfer module (300), and since the configuration and operating structure of each are the same as those described in the heavy object receiving module (20a), a detailed description thereof is omitted.

[0040] When looking at the process of reversing the heavy object (30) through the heavy object receiving module (20a) and the heavy object releasing module (20b), first, as shown in FIG. 2a, the heavy object (30) is supplied to the heavy object receiving module (20a) from a separate external transfer device.

[0041] At this time, the heavy material (30) is a roll-shaped heavy material, and a shaped portion (32) is formed at one end of the axial direction of the raw material wound on the core pipe (31). For convenience, the shaped portion (32) is defined as a part different from the rest of the raw material. When the heavy material (30) is inserted into the heavy material receiving module (20a) in a direction in which the shaped portion (32) of the heavy material (30) is exposed to the front based on FIG. 2a, when the inversion process is completed, the shaped portion (32) of the heavy material (30) is inverted and positioned in a direction in which it is exposed to the rear, as shown in FIG. 2d.

[0042] As shown in FIG. 2a, during the process of supplying a heavy object (30) to the heavy object receiving module (20a), the heavy object receiving module (20a) and the heavy object releasing module (20b) maintain a parallel arrangement facing the same direction. That is, the insertion guide bodies (210) of the heavy object receiving module (20a) and the heavy object releasing module (20b) are arranged parallel to each other facing forward.

[0043] Subsequently, as illustrated in FIG. 2b, the heavy load receiving module (20a) and the heavy load discharging module (20b) rotate in a direction facing each other. Each can rotate clockwise or counterclockwise by 90°, and this can be achieved through the rotation synchronization module (400). When the rotation process is completed in this manner, the insertion guide bodies (210) of the heavy load receiving module (20a) and the heavy load discharging module (20b) are positioned coaxially with each other.

[0044] In this state, as illustrated in FIG. 2c, the push transfer module (300) of the heavy object receiving module (20a) operates to push the heavy object (30) outward along the insertion guide body (210). As the heavy object (30) is pushed outward from the heavy object receiving module (20a), it is simultaneously inserted into the insertion guide body (210) of the heavy object discharging module (20b). When the push transfer module (300) completely pushes out the heavy object (30), the heavy object (30) is fully inserted into the insertion guide body (210) of the heavy object discharging module (20b).

[0045] In this state, when the heavy object receiving module (20a) and the heavy object discharging module (20b) are rotated so that they are positioned parallel to each other as shown in FIG. 2d, the heavy object (30) inserted into the insertion guide body (210) of the heavy object discharging module (20b) has the shaped part (32) positioned on the rear side, and the arrangement direction of the heavy object (30) is reversed compared to the state shown in FIG. 2a.

[0046] Afterwards, the push transfer module (300) of the heavy object release module (20b) operates to push the heavy object (30) along the insertion guide body (210) and transfer it to a separate transfer device in an inverted state.

[0047] The operating state of the heavy object receiving module (20a) and the heavy object releasing module (20b) can be controlled via a separate control unit (not shown). That is, when the heavy object (30) is fully inserted into the heavy object receiving module (20a), the heavy object receiving module (20a) and the heavy object releasing module (20b) can be controlled to rotate in opposite directions. Additionally, when this rotation is completed and they are positioned in opposite directions, the heavy object (30) can be controlled to be pushed into the heavy object releasing module (20b) via the push transfer module (300) of the heavy object receiving module (20a). When the heavy object (30) is fully inserted into the heavy object releasing module (20b), the heavy object receiving module (20a) and the heavy object releasing module (20b) can be controlled to rotate in a direction in which they are positioned parallel to each other.

[0048] At this time, a weight detection sensor (240) capable of detecting whether a weight (30) is inserted can be mounted on both ends of the insertion guide body (210) as shown in FIG. 4. Various sensors such as proximity sensors, optical sensors, and ultrasonic sensors can be applied to the weight detection sensor (240). The control unit can determine the location of the weight (30) by combining the detection signal values ​​of the two weight detection sensors (240), and based on this, can control the operation of the weight receiving module (20a) and the weight releasing module (20b).

[0049] That is, if a detection signal detecting a weight is generated at both the front and rear weight detection sensors (240), it can be seen that the weight (30) has been successfully inserted into the corresponding insertion guide body (210). If a detection signal is generated only at the front weight detection sensor (240), it can be seen that the weight (30) is being pushed out of the insertion guide body (210) or is being inserted. If no detection signal is generated at both the front and rear weight detection sensors (240), it can be seen that the weight (30) has been completely discharged to the outside.

[0050] A roll weight inversion device according to one embodiment of the present invention can invert a weight (30) and deliver it to the outside in this manner. At this time, the weight receiving module (20a) and the weight releasing module (20b) are configured to allow the core pipe (31) of the weight (30) to be inserted and to deliver it to the outside by pushing out the core pipe (31) of the weight (30). Since the raw material portion of the weight (30) is not gripped or towed, the weight (30) can be inverted and delivered stably without damage to the raw material.

[0051] Next, we will examine the detailed configuration of the inversion device for a roll weight according to one embodiment of the present invention in more detail.

[0052] FIG. 5 is a perspective view schematically illustrating the internal structure of a push transfer module according to one embodiment of the present invention.

[0053] A push transfer module (300) according to one embodiment of the present invention is configured to push a heavy object (30) inserted into an insertion guide body (210) outward, and may include a main body housing (310), a push moving body (320), and a push driving unit (330).

[0054] The main body housing (310) has a structure having an internal receiving space and is coupled to the upper part of the vertical body portion (120) of the base rotating body (100), and horizontal guide rails (311) are formed on both sides. As shown in FIG. 3, an upper cover (312) is coupled to the upper surface of the main body housing (310), and FIG. 5 shows the state with the upper cover (312) removed. A push drive unit (330) is disposed in the internal space of the main body housing (310).

[0055] The push drive unit (330) is configured to be positioned inside the main body housing (310) and to move the push moving body (320) along the guide rail (311), and may be configured to include a lead screw (331) coupled inside the main body housing (310) in a direction parallel to the guide rail (311), a linear moving block (332) that moves linearly along the lead screw (331), and a push drive motor (333) that rotates the lead screw (331).

[0056] In this way, the push drive unit (330) is coupled to the vertical body part (120) of the base rotating body (100) so as to protrude forward, and is configured to drive via a lead screw (331) so as to minimize the space protruding backward from the vertical body part (120). Accordingly, as described above, the rotation radius (R) is reduced when the heavy material receiving module (20a) and the heavy material outgoing module (20b) rotate, thereby improving the space efficiency of the process line.

[0057] The push moving body (320) is movably coupled along the guide rail (311) of the main body housing (310) and is positioned so that its lower end penetrates the insertion guide body (210). More specifically, the push moving body (320) is configured to include a push body portion (321) positioned to penetrate the insertion guide body (210) in a flat shape, and a push wing portion (322) whose upper end is coupled to the linear moving block (332) and moves together with the linear moving block (332), and whose lower end is coupled to the push body portion (321).

[0058] Since the push moving body (320) has a push body portion (321) that penetrates the insertion guide body (210), when the push moving body (320) moves forward, the push body portion (321) moves forward along the insertion guide body (210) and can push the heavy object (30) inserted into the insertion guide body (210) outward.

[0059] FIG. 6 is a horizontal cross-sectional view illustrating the structure of a clamp module according to one embodiment of the present invention, FIG. 7 is a horizontal cross-sectional view illustrating the clamping operation process of a clamp module according to one embodiment of the present invention, and FIG. 8 is a horizontal cross-sectional view illustrating the operation process of transporting a heavy object in a clamp module according to one embodiment of the present invention.

[0060] A clamp module (200) according to one embodiment of the present invention is mounted on a heavy object receiving module (20a) and a heavy object outgoing module (20b) as described above, is formed to allow the core pipe (31) of the heavy object (30) to be inserted, and operates to fix the inner surface of the core pipe (31) by pressing it while the core pipe (31) is inserted.

[0061] This clamp module (200) is mounted so as to protrude forward on the front surface of the vertical body portion (120) of the base rotating body (100) so that the core pipe (31) of the heavy object (30) can be inserted, and includes an insertion guide body (210) that is mounted protrudingly on the base rotating body (100) in a hollow cylindrical shape so that the core pipe (31) can be inserted as described above. In addition, it may include a clamping block (220) that is movably mounted inside the insertion guide body (210) so as to protrude or be retracted from the outer surface of the insertion guide body (210), and a clamping operation module (230) that moves the clamping block (220) to protrude or be retracted.

[0062] The clamping operating module (230) is coupled to the insertion guide body (210) so as to be linearly movable in the forward and backward directions along the longitudinal direction, and the clamping block (220) can be configured to protrude or retract in conjunction with the linear movement of the clamping operating module (230). That is, the clamping block (220) can be configured to protrude or retract in conjunction with the clamping operating module (230), which operates mechanically rather than by a separate electrical configuration.

[0063] At this time, the clamping block (220) can protrude from the insertion guide body (210) to press and fix the inner surface of the core pipe (31). That is, when the clamping block (220) protrudes from the insertion guide body (210), it presses the inner surface of the core pipe (31), and the heavy object (30) can be fixed by this pressing force. Conversely, when the clamping block (220) is inserted into the insertion guide body (210), the pressing force of the clamping block (220) on the inner surface of the core pipe (31) is released, so the heavy object (30) is released from fixation.

[0064] These clamping modules (200) can operate to secure a weight (30) inserted into an insertion guide body (210) while the weight receiving module (20a) and the weight releasing module (20b) rotate from the state of FIG. 2a to the state of FIG. 2b or from the state of FIG. 2c to the state of FIG. 2d.

[0065] For example, when a heavy object (30) is inserted into the insertion guide body (210) of the heavy object receiving module (20a), if the heavy object receiving module (20a) rotates without securing the heavy object (30), there is a risk that the heavy object (30) may be dislodged from the insertion guide body (210) due to centrifugal force or other external forces generated during the rotation process. Therefore, it may be desirable for the clamp module (200) to operate to secure the heavy object (30) inserted into the insertion guide body (210) during the rotation process of the heavy object receiving module (20a).

[0066] Of course, the clamping module (200) operates to release the fixed state of the heavy object (30) during operations such as pushing the heavy object (30) by the push transfer module (300).

[0067] To examine the operating structure of the clamping module (200) in more detail, first, as shown in FIGS. 6 to 8, an inclined surface (221) is formed on the inner side of the clamping block (220).

[0068] The clamping operation module (230) may include an operation rod (231) coupled to the internal space of the insertion guide body (210) so as to be linearly movable in the forward and backward directions, and a pressure inclined block (232) coupled to the outer surface of the operation rod (231) and having an inclined surface (2321) formed on its outer surface so as to make surface contact with the inclined surface (221) of the clamping block (220).

[0069] According to this structure, when the pressure inclined block (232) and the clamping block (220) are in mutual surface contact through the inclined surface (221, 2321) and the pressure inclined block (232) moves in a straight line in the forward and backward direction together with the operating rod (231), the clamping block (220) moves along the inclined surface (221) and protrudes or retracts.

[0070] At this time, the inclined surfaces (221, 2321) of the pressure inclined block (232) and the clamping block (220) may be formed so that the clamping block (220) protrudes when the operating rod (231) moves backward from the reference position (X0), and the clamping block (220) is retracted when the operating rod (231) moves back to the reference position (X0). In this case, the operating rod (231) may be configured to move backward a certain distance by the push transfer module (300).

[0071] Additionally, the clamping operation module (230) may further include a rod connecting body (233), a guide bar (234), a first spring (235), and a second spring (236).

[0072] The rod connecting body (233) is coupled to the rear end of the operating rod (231) and can be positioned so that it moves together with the operating rod (231) and both ends are exposed to the outside of the insertion guide body (210). An opening (211) is formed on the side of the insertion guide body (210) so that the rod connecting body (233) passes through and is exposed to the outside, and the opening (211) can be formed in a slot shape that is long for a certain distance in the front-rear direction to allow the rod connecting body (233) to move back and forth. That is, the rod connecting body (233) can move in the front-rear direction by the distance of the opening (211), and the operating rod (231) connected to the rod connecting body (233) can also move in the front-rear direction by that distance.

[0073] The guide bar (234) is coupled to the base rotating body (100) so as to be movable in the forward and backward directions, and is coupled through both ends of the rod connecting body (233) to guide the movement path of the rod connecting body (233). The push transfer module (300) can be configured to move the guide bar (234) backward.

[0074] The first spring (235) is positioned between the rod connecting body (233) and the base rotating body (100) and is formed to apply an elastic force in the forward direction to the rod connecting body (233). The first spring (235) is positioned in a manner that penetrates the guide bar (234) and is guided by the guide bar (234).

[0075] The second spring (236) is positioned in a manner that penetrates the guide bar (234) and is guided by the guide bar (234), and is positioned so that both ends are supported by the flange portion (2341) formed at the front end of the guide bar (234) and the rod connecting body (233).

[0076] In this case, the guide bar (234) can be configured to move backward by the push transfer module (300), and the rod connecting body (233) can be configured to move backward by the elastic force of the second spring (236) in accordance with the backward movement of the guide bar (234), and as the operating rod (231) moves backward together with the backward movement of the rod connecting body (233), the clamping block (220) is protruded.

[0077] This clamp module (200) can be configured so that the operating rod (231) moves backward by the operation of the push transfer module (300), and more specifically, the push body part (321) of the push transfer body (320) of the push transfer module (300) moves backward and moves the operating rod (231) backward.

[0078] The push body part (321) is coupled through the insertion guide body (210) and is configured to move back and forth along the insertion guide body (210). Since the rod connecting body (233) of the clamp module (200) is positioned to protrude from the outer surface of the insertion guide body (210), when the push body part (321) moves backward, the rod connecting body (233) is pressed by the push body part (321) and moves backward. During the process of the push body part (321) moving backward, it may directly engage with the rod connecting body (233) to press the rod connecting body (233), but in one embodiment of the present invention, it is configured to press the rod connecting body (233) by the elastic force of the second spring (236).

[0079] Meanwhile, the push transfer module (300) performs the function of pushing a heavy object (30) by moving the push transfer body (320) forward from the reference position (X0) shown in FIG. 6 to the X2 position as shown in FIG. 8, and in addition, it can move backward to the X1 position as shown in FIG. 7 to operate the fixing function of the clamping module (200). The operating state of this push transfer module (300) can be controlled by the control unit. That is, the push transfer body (320) can be controlled to move forward while pushing the heavy object (30), and to move backward for the operation of the fixing function of the clamping module (200).

[0080] As shown in FIG. 6, when the push moving body (320) is positioned at the reference position (X0) and then moves backward to the X1 position as shown in FIG. 7, the push moving body (320) presses the guide bar (234) backward, and accordingly, the second spring (236) is compressed and presses the rod connecting body (233) backward by elastic force. As the rod connecting body (233) presses backward, the operating rod (231) moves backward and the first spring (235) is compressed. As the operating rod (231) moves backward, the pressure inclined block (232) moves backward, and the clamping block (220) in contact with the pressure inclined block (232) and the inclined surface protrudes from the insertion guide body (210) to press and fix the core pipe (31) of the heavy object (30).

[0081] As shown in enlarged views (a) and (b) of FIG. 7, a gap (t) may exist between the inner surface of the core pipe (31) of the weight (30) and the outer surface of the insertion guide body (210) for smooth movement of the weight (30), and as the clamping block (220) moves outward by the pressure inclined block (232), the clamping block (220) presses and fixes the inner surface of the core pipe (31).

[0082] At this time, the protrusion height of the clamping block (220) corresponding to the movement distance of the push moving body (320) can be designed to be larger than the gap (t) between the inner surface of the core pipe (31) and the outer surface of the insertion guide body (210). In this case, during the intermediate process of the push moving body (320) moving backward, the clamping block (220) comes into contact with and pressurizes the inner surface of the core pipe (31). As the push moving body (320) moves backward further in this state, the first spring (235) and the second spring (236) are compressed, and the pressurized state of the clamping block (220) against the core pipe (31) is maintained by the elastic force of the extruded first spring (235) and the second spring (236).

[0083] In addition, as the clamping block (220) contacts the inner surface of the core pipe (31), the compression of the first spring (235) and the second spring (236) begins simultaneously, thereby preventing the generation of excessive contact force during the process of the clamping block (220) contacting the core pipe (31) and maintaining a stable operating state. In this respect, the first spring (235) and the second spring (236) act as cushioning materials during the process of the clamping block (220) contacting the core pipe (31).

[0084] Afterwards, when the push moving body (320) returns to the reference position (X0), the rod connecting body (233) and the operating rod (231) move forward by the elastic force of the first spring (235) and return to the reference position, and accordingly, the clamping block (220) moves along the inclined surface and is drawn into the interior of the insertion guide body (210), thereby releasing the fixation of the heavy object (30). Afterwards, as shown in FIG. 8, the push moving body (320) continues to move forward to the X2 position to push the heavy object (30) out.

[0085] FIG. 9 is a perspective view illustrating the configuration of a rotation synchronization module according to an embodiment of the present invention, FIG. 10 is a bottom perspective view illustrating the configuration of a rotation synchronization module according to an embodiment of the present invention, and FIG. 11 is a cutaway perspective view illustrating the configuration of a rotation synchronization module according to an embodiment of the present invention.

[0086] A rotation synchronization module (400) according to one embodiment of the present invention is configured to rotate the heavy object receiving module (20a) and the heavy object discharging module (20b) by synchronizing them so that the heavy object receiving module (20a) and the heavy object discharging module (20b) rotate simultaneously in a direction in which they are positioned opposite each other or parallel to each other.

[0087] The rotation synchronization module (400) may be configured to include a first rotation gear (410), a second rotation gear (420), a driving gear (430), and a driving motor (440) that rotates the driving gear (430).

[0088] The first rotating gear (410) is rotatably coupled to the lower surface of the base frame (10) and is configured to be connected to the heavy load receiving module (20a) to rotate together.

[0089] The second rotating gear (420) is rotatably coupled to the lower surface of the base frame (10) and connected to the heavy-duty delivery module (20b) to rotate together, and is configured to mesh with the first rotating gear (410) to rotate simultaneously.

[0090] The drive gear (430) is rotatably coupled to the lower surface of the base frame (10) and is configured to mesh with the first rotating gear (410) and rotate simultaneously with the first rotating gear (410).

[0091] The drive motor (440) is coupled to the rotation axis of the drive gear (430) and configured to drive the drive gear (430) to rotate.

[0092] According to this structure, when the drive motor (440) drives the drive gear (430) to rotate, the first rotating gear (410) rotates, and the second rotating gear (420) rotates together with the first rotating gear (410). The first rotating gear (410) and the second rotating gear (420) rotate in opposite directions.

[0093] Accordingly, when the heavy material receiving module (20a) and the heavy material discharging module (20b) rotate in directions facing each other or in directions arranged parallel to each other, the heavy material receiving module (20a) and the heavy material discharging module (20b) rotate simultaneously at the same speed by the rotation synchronization module (400).

[0094] In this way, the heavy object receiving module (20a) and the heavy object releasing module (20b) rotate at the same speed and by the same angle, so the alignment state between them is accurately maintained as set.

[0095] Meanwhile, a rotation detection dog (101) (see FIG. 3) is attached to one side of each of the heavy object receiving module (20a) and the heavy object releasing module (20b), and a dog detection sensor (460) is mounted on the base frame (10) to detect the rotation detection dog (101) when the heavy object receiving module (20a) and the heavy object releasing module (20b) are rotated in a direction in which they are positioned facing each other or parallel to each other.

[0096] Through these dog and dog detection sensors, the rotational state of the heavy object receiving module (20a) and the heavy object outgoing module (20b) can be accurately detected, and if an error occurs in the rotational state, it can be controlled to output a separate alarm or warning signal.

[0097] The first rotating gear (410) is coupled to the lower end of the first rotating shaft (411) that penetrates the base frame (10) vertically and rotates together with the first rotating shaft (411), and the heavy load receiving module (20a) is coupled to the upper end of the first rotating shaft (411) and is seated and coupled to the first rotating plate (412) which rotates together with the first rotating shaft (411). The first rotating shaft (411) is rotatably coupled to the base frame (10) through a bearing (401), and the first rotating plate (412) can be configured to be connected to the inner ring portion of the bearing (401) and rotate together with the inner ring.

[0098] The second rotating gear (420) is coupled to the lower end of the second rotating shaft (421) that penetrates the base frame (10) vertically and rotates together with the second rotating shaft (421), and the heavy-duty shipping module (20b) is coupled to the upper end of the second rotating shaft (421) and is seated and coupled to the second rotating plate (422) which rotates together with the second rotating shaft (421). The second rotating shaft (421) is rotatably coupled to the base frame (10) through a bearing (401), and the second rotating plate (422) can be configured to be connected to the inner ring portion of the bearing (401) and rotate together with the inner ring.

[0099] At this time, the first rotating gear (410) and the first rotating shaft (411) may be coupled to rotate together as a single unit, but in one embodiment of the present invention, the first rotating gear (410) and the first rotating shaft (411) may be coupled to each other by a separate friction generating means (450) so that they rotate together by mutual frictional force. Likewise, the second rotating gear (420) and the second rotating shaft (421) may also be coupled to each other by a separate friction generating means (450) so that they rotate together by mutual frictional force.

[0100] That is, the first rotating gear (410) and the first rotating shaft (411) rotate together by the frictional force generated by the friction generating means (450). In this case, if an external force greater than the frictional force is applied, the first rotating gear (410) and the first rotating shaft (411) will slip and will not rotate together. The same applies to the second rotating gear (420) and the second rotating shaft (421).

[0101] In this way, the first rotating gear (410) and the first rotating shaft (411) are coupled through the friction generating means (450), and the second rotating gear (420) and the second rotating shaft (421) are coupled. Therefore, when an unintended large external force is applied during the process of the first rotating gear (410) and the second rotating gear (420) rotating simultaneously, slip of the rotating gear can occur without damaging the rotating gear or other parts, thereby mitigating the impact.

[0102] In particular, it is advantageous in terms of maintenance in that, when the synchronous rotation of the first rotating gear (410) and the second rotating gear (420) is abnormal due to assembly errors or usage errors, the rotation alignment position with respect to the rotation axis of the first rotating gear (410) or the second rotating gear (420) can be adjusted relatively easily.

[0103] It may be configured to include a friction generating means (450), a coupling ring (451), and a friction controlling member (453).

[0104] A coupling ring (451) coupled between the first rotating gear (410) and the first rotating shaft (411) is formed in a ring shape and coupled to the center hole of the first rotating gear (410) to rotate integrally with the first rotating gear (410), and a protruding step (452) protruding inwardly is formed on the upper circumference. According to this structure, an insertion groove space is formed between the inner surface of the coupling ring (451) and the outer surface of the first rotating shaft (411).

[0105] The coupling ring (451) coupled between the second rotating gear (420) and the second rotating shaft (421) is also formed in the same shape, so a description of this is omitted.

[0106] A friction adjustment member (453) coupled between the first rotating gear (410) and the first rotating shaft (411) is formed in a ring shape to be inserted between the inner surface of the coupling ring (451) and the outer surface of the first rotating shaft (411), and is formed so that its radial thickness can be adjusted by user operation. For example, as shown in FIG. 11, by rotating a separate operating bolt (454), the radial thickness (d) of the friction adjustment member (453) can be increased or decreased, and through this change in thickness, the frictional force on the first rotating shaft (411) and the first rotating gear (410) can be adjusted. The radial thickness adjustment structure of the friction adjustment member (453) can be implemented by a method in which a wedge-shaped block expands or contracts radially according to the up-and-down movement caused by the operation of the operating bolt (454). Of course, this is exemplary, and a thickness-adjustable structure can be implemented through various mechanical elements.

[0107] The friction control member (453) coupled between the first rotating gear (410) and the first rotating shaft (411) is also formed in the same shape, so a description thereof is omitted.

[0108] The rotation synchronization module (400) according to one embodiment of the present invention can adjust the frictional force between the rotation axis and the rotation gear through the friction adjustment member (453) in this way, thereby allowing the degree of slip to be adjusted according to the user's needs, preventing damage caused by external forces, and easily adjusting the alignment state even when the alignment state of the rotation gear is misaligned due to errors, etc.

Accordingly, the embodiments disclosed in the present invention are intended to explain, not limit, the technical concept of the present invention, and the scope of the technical concept of the present invention is not limited by these embodiments.
