[0035] As illustrated in FIGS. 1 to 13, a conveyor for a food quick-freezing device according to an embodiment of the present invention comprises a front frame (100), a rear frame (200), a front rotation shaft (300), a rear rotation shaft (400), a driving motor (500), a front sprocket (600), a rear sprocket (700), a chain (800), a tray (900), a heating unit (1000), a pin pressurizing unit (1100), a first striking unit (1200), and a second striking unit (1300).

[0036] As illustrated in FIGS. 1 and 2, the conveyor of the present invention is installed to pass through the food quick-freezing device (10) from front to back. Accordingly, the conveyor of the present invention feeds food supplied from the front of the quick-freezing device (10) into the quick-freezing device (10), freezes the food, and then transports the food to the rear of the quick-freezing device (10) and discharges it.

[0037] The front frame (100) is installed at the front of the rapid freezing device (10). As shown in Fig. 4, the front frame (100) includes two front side plates (110) that are installed spaced apart from each other on the left and right so as to support both ends of the front rotation shaft (300).

[0038] The rear frame (200) is installed at the rear of the rapid freezing device (10). As shown in FIGS. 4 and 5, the rear frame (200) includes two rear side plates (210) that are installed spaced apart from each other on the left and right so as to support both ends of the rear rotation shaft (400).

[0039] The front rotation shaft (300) is installed on the inside of the front frame (100), as shown in FIGS. 3 and 4. The front rotation shaft (300) is arranged to extend left and right, and both ends are rotatably supported on the two front side plates (110), respectively.

[0040] The rear rotation shaft (400) is installed on the inside of the rear frame (200), as shown in FIGS. 3 to 5. The rear rotation shaft (400) is arranged to extend left and right, and both ends are rotatably supported on the two rear side plates (210).

[0041] The above driving motor (500) is connected to the front rotation shaft (300) or the rear rotation shaft (400), as shown in FIGS. 4 and 5, and rotates the front rotation shaft (300) or the rear rotation shaft (400).

[0042] As shown in Fig. 4, two front sprockets (600) are provided and installed at each end of the front rotation shaft (300).

[0043] As shown in FIGS. 4 and 5, two rear sprockets (700) are provided and installed at each end of the rear rotation shaft (400).

[0044] As shown in FIGS. 4 and 5, the above chain (800) is provided in two pieces and is arranged spaced apart from each other on the left and right. One of the two chains (800) is installed to connect the front sprocket (600) installed at one end of the front rotation shaft (300) and the rear sprocket (700) installed at one end of the rear rotation shaft (400), and the other of the two chains (800) is installed to connect the front sprocket (600) installed at the other end of the front rotation shaft (300) and the rear sprocket (700) installed at the other end of the rear rotation shaft (400).

[0045] Ultimately, the two chains (800) are installed to be wound around the front sprocket (600) and the rear sprocket (700) and rotated, and accordingly, each chain (800) forms a transfer section (S1) in which it moves from the upper end of the front sprocket (600) to the upper end of the rear sprocket (700), a discharge section (S2) in which it rotates from the upper end of the rear sprocket (700) to the lower end of the rear sprocket (700), and a return section (S3) in which it moves from the lower end of the rear sprocket (700) to the lower end of the front sprocket (600) and then rotates to the upper end of the front sprocket (600), as shown in FIG. 3.

[0046] As shown in FIGS. 3 to 5, the above trays (900) are provided in multiple numbers and arranged along the two chains (800). Each tray (900) is formed with a receiving portion (910) for containing food. The receiving portion (910) may be formed to be divided into two or more compartments.

[0047] Each of the above trays (900) is connected at both ends to the two chains (800), and thus, the chains (800) rotate to circulate through the transport section (S1), discharge section (S2), and return section (S3).

[0048] As shown in FIGS. 6 and 7, the bottom of the receiving portion (910) of the tray (900) is provided with an insertion hole (930) formed vertically and penetratingly, and a discharge pin (940) inserted into the insertion hole (930) so as to be movable up and down. The insertion hole (930) and the discharge pin (940) are provided in multiple numbers so as to be spaced apart from each other along the length direction and width direction of the tray (900).

[0049] The above discharge pin (940) is raised by the pin pressurizing portion (1100) when the tray (900) reaches the discharge section (S2) to push up the food contained in the receiving portion (910).

[0050] The above tray (900) can be made of stainless steel. Stainless steel is hygienic and has excellent thermal conductivity, allowing food contained in the receiving portion (910) to be frozen and thawed smoothly, making it a suitable material for the tray (900).

[0051] If necessary, a support plate (950) made of polytetrafluoroethylene material may be installed on the bottom of the receiving portion (910). Accordingly, frozen food can be easily separated and discharged from the bottom of the receiving portion (910).

[0052] The heating unit (1000) is installed in the rear frame (200) as shown in FIGS. 3 to 5, and is intended to heat the surface of food contained in the tray (900) that has passed through the rapid freezing device (10). That is, the heating unit (1000) thaws the surface of food frozen on the inner wall and bottom of the receiving portion (910) of the tray (900), thereby enabling food to be smoothly discharged from the tray (900) arranged in the discharge section (S2).

[0053] As illustrated in FIG. 8, the heating unit (1000) comprises: a discharge chamber (1010) that is installed to extend along the longitudinal direction of the tray (900) and has a plurality of discharge holes (1011) formed on the upper surface; a hot air blower (1020) for supplying hot air to the discharge chamber (1010); and a duct (1030) that connects the discharge chamber (1010) and the hot air blower (1020). Accordingly, the heating unit (1000) is installed to be disposed on the lower side of the tray (900) arranged in the transport section (S1) and is configured to discharge hot air toward the tray (900) that has passed through the rapid freezing device (10).

[0054] And as illustrated in FIGS. 6 and 7, a plurality of ventilation holes (920) are formed on the bottom of the receiving portion (910) of the tray (900) to allow hot air discharged from the heating portion (1000) to flow into the receiving portion (910). With this configuration, the hot air discharged from the heating portion (1000) can smoothly flow between the bottom of the receiving portion (910) and the food, thereby allowing the inner wall of the receiving portion (910) and the surface of the food frozen on the bottom to be quickly thawed.

[0055] In the above heating unit (1000), the duct (1030) is connected to one side of the discharge chamber (1010), and the discharge chamber (1010) is configured such that its vertical width narrows from one side to the other. Accordingly, the hot air discharged from each discharge hole (1011) can be discharged at a uniform pressure.

[0056] The above pin pressurizing unit (1100) is installed on the inside of the rear frame (200) to raise the discharge pin (940) of the tray (900) arranged in the discharge section (S2), and as shown in FIGS. 6 and 7, comprises a plurality of pressure plates (1110) arranged to be spaced apart from each other along the longitudinal direction of the rear rotation shaft (400); and a plurality of spacers (1120) coupled to the rear rotation shaft (400) so as to be arranged between each of the pressure plates (1110).

[0057] The above pressure plate (1110) is connected to the rear rotation shaft (400) at the center and rotates together with the rear rotation shaft (400). The outer circumferential surface of the pressure plate (1110) is arranged close to the lower surface of the tray (900) arranged in the discharge section (S2).

[0058] The above spacer (1120) maintains the spacing of each pressure plate (1110) so that the spacing of each pressure plate (1110) corresponds to the spacing of each discharge pin (940) arranged along the length direction of the tray (900).

[0059] According to the pin pressurizing unit (1100) configured as described above, after the outer surface of the pressurizing plate (1110) comes into contact with the discharge pin (940) of the tray (900) that has reached the discharge section (S2), the discharge pin (940) is gradually raised, and the discharge pin (940) raised in this way pushes up the food contained in the receiving section (910) of the tray (900), so that the food can be easily poured out and discharged from the receiving section (910) while the tray (900) is rotated and turned over in the discharge section (S2).

[0060] The first striking portion (1200) is installed on the rear frame (200) and strikes the tray (900) arranged in the discharge section (S2), and as shown in FIGS. 9 to 11, comprises two rotary tables (1210) rotatably installed on both sides of the rear frame (200); an operating wheel (1220) installed on each end of the rear rotation shaft (400) to contact the rotary table (1210) and rotate together with the rear rotation shaft (400) to repeatedly rotate the end of the rotary table (1210) up and down; a crossbar (1230) installed to connect the ends of the two rotary tables (1210); And it comprises a striking member (1240) installed on the crossbar (1230) and striking the upper surface of the tray (900) arranged in the discharge section (S2) by rotating the end of the rotating member (1210) from the upper side to the lower side.

[0061] The above-mentioned rotary table (1210) is configured in the shape of a rod extending forward and backward, such that the front end is rotatably connected to the rear frame (200), and the other end is extended so as to be placed on the upper side of the tray (900) placed in the discharge section (S2). At this time, the other end of the rotary table (1210) is formed to be bent downward, so as to be placed so as to enter the discharge section (S2) and face the tray (900) placed obliquely.

[0062] The above-described turntable (1210) is provided with a protrusion (1211) protruding toward the operating wheel (1220), and a roller (1212) that is rotatably installed at the end of the protrusion (1211) and comes into contact with the outer surface of the operating wheel (1220). The turntable (1210) is repeatedly rotated up and down as shown in [A] and [B] of FIG. 9 by the roller (1212) rolling along the outer surface of the operating wheel (1220).

[0063] The above crossbar (1230) is configured in the shape of a bar extending left and right, and both ends are connected to the other ends of the two rotating stands (1210).

[0064] As illustrated in Fig. 10, the above striking member (1240) is provided in multiple numbers and installed spaced apart from each other along the length direction of the crossbar (1230). The striking member (1240) is configured in the shape of a bar extending vertically and is coupled to penetrate the crossbar (1230). A rubber bumper (1241) is mounted on the lower end of the striking member (1240). The bumper (1241) reduces noise generated when the striking member (1240) strikes the upper surface of the tray (900) and prevents damage to the striking member (1240) and the tray (900).

[0065] The above-mentioned operating wheels (1220) are provided in two numbers and are installed at each end of the rear rotation shaft (400). The operating wheels (1220) are provided with a number of operating projections (1221) that protrude along the outer circumference and come into contact with the rollers (1212) of the rotating table (1210).

[0066] The above-mentioned operating projection (1221) is formed to include an inclined surface (1222) formed on a side facing the direction in which the operating wheel (1220) rotates to push up the roller (1212); and a drop surface (1223) formed on a side opposite to the direction in which the operating wheel (1220) rotates to cause the roller (1212) passing through the inclined surface (1222) to rapidly descend.

[0067] Finally, the end of the rotary table (1210) is rotated upward as shown in [A] of FIG. 9 by the roller (1212) rolling along the inclined surface (1222) when the operating wheel (1220) rotates, and then is rotated downward as shown in [B] of FIG. 9 by the roller (1212) passing through the inclined surface (1222) rapidly descending along the falling surface (1223). Then, the striking member (1240) strikes the upper surface of the tray (900) arranged in the discharge section (S2) as the end of the rotary table (1210) is rotated downward, and the food contained in the tray (900) can be easily discharged by the impact caused by this striking by being separated from the tray (900).

[0068] As illustrated in FIGS. 9 and 11, the operating wheel (1220) is coupled to the rear sprocket (700) by a plurality of bolts (1250) that penetrate through the operating wheel and are fastened to the rear sprocket (700). Accordingly, the operating wheel (1220) is formed with a plurality of bolt insertion holes (1224) through which each of the bolts (1250) passes. Each of the bolt insertion holes (1224) is formed to extend in an arc shape with the rear rotation axis (400) as the center. According to this configuration, when the operating wheel (1220) is coupled to the rear sprocket (700), the angle at which each of the operating protrusions (1221) is arranged can be adjusted and fixed, thereby controlling the timing at which the striking member (1240) strikes the tray (900).

[0069] The second striking unit (1300) is installed on the rear frame (200) and strikes the tray (900) arranged in the return section (S3), and as shown in FIGS. 12 and 13, comprises: a central shaft (1310) installed on the upper side of the tray (900) arranged in the return section (S3) so as to extend along the longitudinal direction of the tray (900); a striking motor (1320) connected to the central shaft (1310) and rotating the central shaft (1310); and a striking mechanism (1330) installed on the central shaft (1310) so as to protrude radially and strike the tray (900) by rotating together with the central shaft (1310).

[0070] And the above striking mechanism (1330) comprises, as illustrated in FIG. 13, a rotating plate (1331) coupled to the central axis (1310); a plurality of mounting portions (1332) formed on the outer surface of the rotating plate (1331) to protrude radially from the rotating plate (1331); and a striking roll (1333) rotatably installed on the mounting portions (1332) to strike the tray (900) arranged in the return section (S3) by the rotation of the rotating plate (1331).

[0071] The above striking mechanism (1330) is provided in two or more pieces and arranged along the longitudinal direction of the central axis (1310). The striking rolls (1333) provided in each striking mechanism (1330) may be arranged with their phases different.

[0072] Each striking mechanism (1330) is provided with a pair of rotating plates (1331) spaced apart along the longitudinal direction of the central axis (1310).

[0073] The above striking roll (1333) is configured in the shape of a pipe connecting a pair of rotating plates (1331).

[0074] The above-mentioned striking roll (1333) is installed so as to be fitted to the outer side of the roll shaft (1334) that is horizontally fixed to the above-mentioned mounting portion (1332). At this time, the inner diameter of the striking roll (1333) is formed to be larger than the diameter of the roll shaft (1334), so that the striking roll (1333) can move up and down around the roll shaft (1334). According to this structure, by adjusting the gap between the tray (900) and the striking mechanism (1330) so that the striking roll (1333) can strike the tray (900) only when it moves downwards of the roll shaft (1334), the striking mechanism (1330) can be prevented from directly hitting the tray (900), and accordingly, the tray (900) can be prevented from being deformed by the striking mechanism (1330).

[0075] Finally, the second striking portion (1300) strikes the tray (900) placed in the return section (S3) to shake off food residue stuck to the receiving portion (910) of the tray (900).

[0076] According to the conveyor for a food quick-freezing device according to the embodiment of the present invention configured as described above, since a tray (900) capable of accommodating noodle-type food is integrally provided on the conveyor, a separate device for managing the tray (900) for containing noodle-type food and the tray (900) is not required, and accordingly, equipment costs can be reduced and the operation and management of the conveyor are facilitated.

[0077] While the present invention has been described above with reference to limited embodiments and drawings, these are merely illustrative, and it will be apparent to those skilled in the art that various modifications are possible within the scope of the technical concept of the present invention. Accordingly, the scope of protection of the present invention should be determined by the description of the claims and their equivalents.
