[0051] Figures 4 and 5 are drawings showing the schematic configuration of the shock absorber of Figure 3.

[0052] Referring to FIGS. 4 and 5, an impact cushioning member (430) according to one embodiment of the present invention includes an installation groove (431), an installation frame (432), a belt fastening rail (433), a cushioning module (434), and a module cover (435).

[0053] The installation groove (431) is formed as a recess on the upper side of the conveyor table (410) to provide a space for installing the components of the shock absorber (430). The size and shape of the installation groove (431) are determined according to the size and arrangement of the components of the shock absorber (430).

[0054] The installation frame (432) is formed in a "□" shape with a left-right length corresponding to the left-right width of the conveyor belt (420) and is installed along the upper edge of the installation groove (431).

[0058] An impact cushioning member (430) according to one embodiment of the present invention having the configuration described above comprises an installation groove (431), an installation frame (432), a belt fastening rail (433), a cushioning module (434), and a module cover (435) that are organically connected to each other to stably support the conveyor belt (420) and effectively cushion the impact generated when the molded product (1) is placed. In particular, a uniform cushioning effect can be provided over the entire area of ​​the conveyor belt (420) through a plurality of cushioning modules (434), and stable transport can be ensured by preventing the conveyor belt (420) from coming off through the belt fastening rail (433).

[0060] Figures 6 and 7 are drawings showing the schematic configuration of the buffer module of Figure 4.

[0061] Referring to FIGS. 6 and 7, a buffer module (434) according to one embodiment of the present invention includes a module support (4341), a support head (4342), a buffer spring (4343), a support plate (4344), a nozzle installation groove (4345), a spray nozzle (4346), and an exhaust passage (4347).

[0062] The module support (4341) is installed upright on the lower side of the installation groove (431) and serves to support the overall structure of the buffer module (434). The module support (4341) is made of a sturdy material such as metal and has sufficient rigidity to withstand the load of the conveyor belt (420) and the molded product (1).

[0063] The support head (4342) is installed to cover the upper side of the module support (4341) and to enable vertical movement. The support head (4342) moves up and down along the module support (4341) and performs a vertical movement in response to an impact applied to the conveyor belt (420).

[0064] The cushioning spring (4343) is installed on the inner side of the support head (4342) and serves to support the support head (4342) while simultaneously cushioning the impact transmitted to the support head (4342). The cushioning spring (4343) uses elastic force to absorb the impact applied to the conveyor belt (420) and dampen vibrations.

[0065] The support plate (4344) is a flat plate-shaped member installed on the upper side of the support head (4342) to support the conveyor belt (420). The support plate (4344) is in direct contact with the conveyor belt (420) and stably supports the conveyor belt (420).

[0066] The nozzle installation groove (4345) is formed at the center of the upper surface of the support plate (4344) to provide a space for installing a spray nozzle (4346). The size and shape of the nozzle installation groove (4345) are determined according to the size and shape of the spray nozzle (4346).

[0067] A flexible tube extending from an external air compressor (not shown) passes through the bottom or side of the support head (4342) and is connected to the injection nozzle (4346).

[0068] The spray nozzle (4346) is installed inside the nozzle installation groove (4345) and serves to receive and spray compressed air. The spray nozzle (4346) sprays compressed air toward the lower part of the conveyor belt (420) to create an air cushion effect that separates the conveyor belt (420) from the support plate (4344) and supports it.

[0069] The discharge passage (4347) is formed to extend along the upper surface of the support plate (4344) from the nozzle installation groove (4345) so that compressed air can be discharged when the conveyor belt (420) covers the nozzle installation groove (4345). The discharge passage (4347) serves as a passage for the compressed air sprayed from the spray nozzle (4346) to be discharged to the outside and contributes to regulating the air cushion pressure formed between the conveyor belt (420) and the support plate (4344).

[0070] A cushioning module (434) according to one embodiment of the present invention having the configuration described above can effectively cushion the impact applied to the conveyor belt (420) by simultaneously applying a mechanical cushioning method using a cushioning spring (4343) and an air pressure cushioning method using a spray nozzle (4346). In particular, by forming an air cushion between the conveyor belt (420) and the support plate (4344) through the spray nozzle (4346), friction is minimized and smooth transport is enabled, and the cushioning spring (4343) can stably respond to large impacts.

[0072] In one embodiment, the conveyor belt (420) may have perforations (421) repeatedly formed so as to discharge a portion of the compressed air sprayed from the spray nozzle (4346).

[0073] The conveyor belt (420) can be configured in the form of a flat belt or a timing belt, etc., which are generally used to transport injection-molded products (1). The material of the conveyor belt (420) can be selected considering wear resistance, heat resistance, chemical resistance, etc., and a pattern or coating can be applied to the surface to prevent slipping of the molded product (1).

[0074] The perforated holes (421) are repeatedly formed at regular intervals along the length and width directions of the conveyor belt (420). The size, shape, and arrangement of the perforated holes (421) are determined by considering the injection pressure of the injection nozzle (4346), the speed of the conveyor belt (420), and the type of molded product (1) being transported. The perforated holes (421) serve to regulate the air cushion pressure formed between the conveyor belt (420) and the support plate (4344) and prevent the conveyor belt (420) from lifting by discharging a portion of the compressed air injected from the injection nozzle (4346) to the outside.

[0075] A conveyor belt (420) according to one embodiment of the present invention having the configuration described above efficiently discharges compressed air through perforated holes (421), thereby optimizing the air cushion effect and enabling stable transport. In addition, foreign matter can be easily discharged through perforated holes (421), making maintenance of the conveyor belt (420) convenient and extending its lifespan.

[0078] Referring to FIG. 8, a support head (4342) according to one embodiment of the present invention includes a first head (4342a), a support insertion groove (4342b), a connecting sphere (4342c), and a second head (4342d).

[0079] The first head (4342a) is positioned on the upper side of the module support (4341) to form the lower structure of the support head (4342). The first head (4342a) is made of a rigid material such as metal and is connected to the module support (4341) to guide the up-and-down movement of the support head (4342).

[0080] The support insertion groove (4342b) is formed on the lower side of the first head (4342a) to provide space for the module support (4341) to be inserted and supported by the cushioning spring (4343). The support insertion groove (4342b) has a size and shape such that the upper part of the module support (4341) can be inserted, and secures sufficient space for the cushioning spring (4343) to be installed.

[0081] The connecting sphere (4342c) is formed in a circular spherical shape and is installed on the upper side of the first head (4342a). The connecting sphere (4342c) acts as a joint connecting the first head (4342a) and the second head (4342d), and enables the second head (4342d) to rotate and tilt relative to the first head (4342a).

[0082] The second head (4342d) is rotatably connected to the connecting sphere (4342c) and fixedly installed on the lower side of the support plate (4344). The second head (4342d) rotates and tilts around the connecting sphere (4342c) and flexibly responds to changes in the inclination of the conveyor belt (420).

[0083] A support head (4342) according to one embodiment of the present invention having the configuration described above can provide stable support by flexibly responding to changes in the inclination of the conveyor belt (420) or uneven load of the molded product (1) through a connecting sphere (4342c) so that the second head (4342d) can freely rotate and tilt relative to the first head (4342a).
