Hereinafter, preferred embodiments of a food transport device and a food packaging system including the same according to the present invention will be described in detail with reference to the attached drawings. In the following description of the present invention, if it is determined that a detailed description of a known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. Throughout the specification, when a part is said to "include" a certain component, this does not mean that other components are excluded, but that other components can be further included, unless specifically stated otherwise.

Referring to FIGS. 1 to 8, a food transport device (1) according to one embodiment of the present invention includes a transport mechanism (11) that grips and transports a bag (100), a transport rail (13) along which the transport mechanism (11) is supported and moves, and a driving unit (15) that drives the transport mechanism (11).

The transport device (1) according to the present invention is a device that automatically grips a bag (100) containing food and transports it for packaging, and in particular, enables the unfolding of the bag (100), the supply of food to the bag (100), and the packaging work after transporting the bag (100) to be performed automatically without a worker by only the operation of a driving unit (15) that moves a transport mechanism (11). The transport device (1) can be applied to a food packaging system that mixes food and supplies it to the bag (100), and transports the bag (100) containing the food to a packaging device to automatically perform packaging. In the food packaging system described below, it will be explained assuming that the side where the food is contained in the bag (100) is the front side, and the side of the packaging device where the bag (100) is transported is the rear side.

The above-described transport mechanism (11) is configured to move by gripping a bag (100) containing food, and moves in the forward and backward directions along the transport rail (13). The transport mechanism (11) presses the upper side of the bag (100) from both sides to grip it, and in the gripped state moves toward the banding packaging device (3) forward along the transport rail (13), and automatically seals the moved bag (100) by the banding packaging device (3). In particular, the transport mechanism (11) automatically performs the unfolding of the bag (100) supplied by the bag supply device (5) described below, the rotation of the rotating housing (23), and the packaging work by the banding packaging device (3) as it moves. Accordingly, the present invention automatically performs the unfolding of the envelope (100), the rotation of the rotating housing (23), and the packaging operation by the banding packaging device (3) by simply moving the transport mechanism (11) in the forward and backward directions by the driving unit (15), thereby simplifying the configuration of the device and minimizing the power consumption while allowing all operations to be performed automatically without a worker. To this end, the transport mechanism (11) may include a gripping unit (111), a moving roller (112), and a gear unit (113).

The above gripping part (111) is configured to grip an envelope (100) and grips the envelope (100) by pressing it on both sides of the envelope (100). As shown in Fig. 5, the gripping part (111) may include a gripping body (111a), a gripping arm (111b), a gripping roller (111c), a tension supporting means (111d), and a tension adjusting means (111e).

The above-mentioned phage main body (111a) is configured to support the configuration of the phage section (111), and phage arms (111b) are rotatably fixed on both sides, and are supported and moved on a transport rail (13).

The above-mentioned phage arm (111b) is configured such that one end is rotatably connected to the phage body (111a), and the other end has a phage roller (111c) formed to press the envelope (100), and a pair is formed on both sides of the phage body (111a). The above-mentioned phage arm (111b) can be formed by dividing into a first arm (111b-1), a second arm (111b-2), and a third arm (111b-3) to form a certain angle, thereby enabling strong pressing and stable phage of the envelope (100).

The first arm (111b-1) is formed to be supported by the transport rail (13), more precisely, the grip adjustment rail (131) described later, and is connected to the second arm (111b-2) at a certain angle. To this end, a rail insertion member (111b-11) is formed at the end of the first arm (111b-1) so that the transport mechanism (11) moves forward and backward while inserted into the grip adjustment rail (131), and the compression and release of the grip roller (111c) for the envelope (100) can be controlled depending on the position at which it is inserted into the inner or outer side of the grip adjustment rail (131). Accordingly, when the transport mechanism (11) moves toward the banding packaging device (3) by gripping the envelope (100), the gripping rollers (111c) on both sides are pressed against the envelope (100), and when the transport is completed and the device moves toward the envelope supply device (5), the pressing is released so that another envelope (100) can be pressed again.

The second arm (111b-2) is connected at one end to the first arm (111b-1) at a certain angle and is rotatably connected to the grip body (111a). In addition, the other end of the second arm (111b-2) is rotatably connected to the third arm (111b-3), and a tension support means (111d) is formed on the second arm (111b-2) to pull the third arm (111b-3).

The third arm (111b-3) is configured such that one end is rotatably connected to the second arm (111b-2) and the other end has a phage roller (111c) formed thereon to press down on the envelope (100), and can be pulled by a tension support means (111d) to strongly press down on the envelope (100).

The above-mentioned phage roller (111c) is configured to be pressed against an envelope (100) to form a phage, and is formed at the end of the third arm (111b-3). In particular, as shown in Fig. 7, the phage roller (111c) may be formed such that the first roller (111c-1) and the third roller (111c-2) are alternately formed in the front-back direction, and the first and second rollers (111c-1, 111c-2) may be formed such that they protrude inwardly to different degrees. Accordingly, when the first roller (111c-1) is formed to protrude more toward the envelope (100) than the third roller (111c-2), the envelope (100) is drawn toward the third roller (111c-2) and gripped, thereby allowing the envelope (100) to be pressed more strongly, and the envelope (100) can be gathered in the front-back direction so that the fastening of the banding pin (333) by the banding packaging device (3) can be made easier. In addition, the third roller (111c-2) can be formed in a pair, upper and lower, so that the pressing force for the envelope (100) can be further increased.

The above tension support means (111d) is configured to pull the third arm (111b-3) so that the squeegee roller (111c) can be pressed more strongly against the envelope (100), and as shown in FIGS. 4 and 5, it is formed on the second arm (111b-2) to pull the third arm (111b-3). The tension support means (111d) can have a pulling force for the third arm (111b-3) by fixing an elastic material such as a spring in a pulled state, and the pulling force can be adjusted by the tension control means (111e).

The above tension adjusting means (111e) is configured to adjust the force with which the third arm (111b-3) is pulled by the tension supporting means (111d), and can be configured to adjust the position at which the tension adjusting means (111e) is fixed on the second arm (111b-2). Accordingly, the tension adjusting means (111e) can be formed to be movable along the second arm (111b-2), and the force with which the tension adjusting means (111e) pulls the third arm (111b-3) can be adjusted depending on the position at which it is fixed on the second arm (111b-2). Accordingly, the tension adjusting means (111e) can appropriately adjust the force with which the paper roller (111c) presses the bag (100) depending on the weight of the food contained in the bag (100), the size and thickness of the bag (100), etc.

The above moving roller (112) is configured to be rotatable on the lower side of the body (111a) and moves along the transport rail (13) so that the transport mechanism (11) can move stably along the transport rail (13).

The above gear part (113) is configured to automatically perform the unfolding of the envelope (100), the supply of food, and the operation of the banding packaging device (3) according to the movement of the above transport mechanism (11), and a gear is formed on the body (111a) so that the operation of other devices can be performed in conjunction by engaging with the gear. The gear part (113) may include a bottom gear (113a), a banding gear (113b), and a tightening gear (113c) as illustrated in FIGS. 7 and 8.

The above-described bottom gear (113a) is formed on the bottom side of the body (111a) and rotates the first and second gears (71, 72) of the support frame (7), which will be described later. In other words, the above-described bottom gear (113a) is formed in the shape of gear teeth and meshes with the first and second gears (71, 72), respectively, according to the movement of the transport mechanism (11), thereby rotating the first and second gears (71, 72). The above-described first and second gears (71, 72) are configured to rotate the rotating housing (23) and the envelope unfolding device (6), respectively, and when rotated by the bottom gear (113a), they rotate the rotating housing (23) or the envelope unfolding device (6). A detailed description thereof will be described later.

The above banding gear (113b) is a gear formed on one side of the body (111a) of the gripper, and rotates the banding gear (311) by engaging with the banding gear (311) of the banding packaging device (3), which will be described later. The banding gear (311) is formed in the banding fastening portion (31) and is configured to allow the banding pin (333) to be wound around and fastened to the envelope (100). As the banding gear (311) rotates by engaging with the banding gear (113b), the fastening of the banding pin (333) is achieved, and through this, the fastening operation of the banding pin (333) can be completed by only moving the transport mechanism (11).

The above tightening gear (113c) is a gear formed on one side of the body (111a) of the gripper, and is configured to rotate the tightening gear (371) of the banding packaging device (3) by engaging with the tightening gear (371) described later. The tightening gear (371) is configured to press and tighten the bag (100) according to its rotation, and the bag (100) is tightened along with the movement of the transport mechanism (11), thereby allowing the fastening of the banding pin (333) to occur smoothly.

The above-mentioned transport rail (13) is configured to form a path along which the transport mechanism (11) is supported and moves, and is formed along the front-back direction from the lower side of the rotating housing (23) to the banding packaging device (3). The above-mentioned transport rail (13) can be formed on both sides of the transport mechanism (11), and allows the moving roller (112) of the transport mechanism (11) to move while being supported. In addition, the above-mentioned transport rail (13) can additionally include a grip adjustment rail (131) into which the rail insertion member (111b-11) of the first arm (111b-1) is inserted and moves.

The above-mentioned grip adjustment rail (131) is configured to move by inserting a rail insertion member (111b-11), and controls the gripping of the envelope (100) by the gripping member (111). To this end, the grip adjustment rail (131) may include an inner rail (131a) and an outer rail (131b), as shown in FIGS. 5 and 6, and may include a control member (131c) that controls movement to the inner rail (131a) or the outer rail (131b). When the above rail insertion member (111b-11) is inserted into the inner rail (131a), the grip arm (111b) is spread apart as shown in FIG. 4, causing the grip roller (111c) to move away from the envelope (100), and when it is inserted into the outer rail (131b), the grip arm (111b) is gathered inward as shown in FIG. 5, causing the grip roller (111c) to come into close contact with the envelope (100). In addition, the inner rail (131a) and the outer rail (131b) are connected to each other at both ends on the front and rear sides as shown in Fig. 6, and one of the inner rail (131a) or the outer rail (131b) is blocked by the adjusting member (131c) to allow the rail insertion member (111b-11) to move to either the inner rail (131a) or the outer rail (131b). Accordingly, when the gripping part (111) grips a bag (100) containing food and moves from the rear to the front, the rail insertion member (111b-11) moves while being inserted into the outer rail (131b), and when the banding packaging device (3) moves from the front to the rear after packaging is completed, the rail insertion member (111b-11) is inserted into the inner rail (131a) and the gripping arm (111b) moves in an opened state to grip another bag (100) containing food at the lower side of the rotating housing (23).

The above driving unit (15) is configured to move the transport mechanism (11) in the forward and backward direction, and transports the bag (100) containing food through the movement of the transport mechanism (11). In particular, the present invention enables efficient operation of the system by performing the unfolding of the bag (100), the supply of food, the tightening of the bag (100), and the fastening of the banding pin (333) only by the forward and backward movement of the transport mechanism (11) according to the operation of the driving unit (15). The driving unit (15) may include a driving motor (151), a first moving gear (152), a third moving gear (153), a driving belt (154), and a chain (155) as illustrated in FIG. 1.

The above driving motor (151) is configured to provide driving force for the transport mechanism (11) to move, and can be formed on the lower side of the support frame (7) to operate, and rotates the first moving gear (152) according to its operation.

The above first moving gear (152) is configured to rotate according to the operation of the driving motor (151), and may be connected to the driving motor (151) by a driving belt (154). The above first moving gear (152) may be formed at the front or rear end of the transfer rail (13), and for example, may be formed at the rear end, and a third moving gear (153) may be formed on the opposite side of the first moving gear (152), for example, at the front end. A chain (155) is connected to the first moving gear (152) and the third moving gear (153) so that the chain (155) can rotate in the forward and backward direction according to the rotation of the first moving gear (152) and the third moving gear (153), and a transport mechanism (11) is connected to the chain (155) so that the transport mechanism (11) can move in the forward and backward direction according to the rotation of the chain (155).

Hereinafter, a food packaging system including a food transport device (1) according to one embodiment of the present invention will be described with reference to FIGS. 1 to 18. The food packaging system includes a food transport device (1), a stirring supply device (2) that mixes food and supplies it to a bag (100), a banding packaging device (3) that winds a banding pin (333) around a bag (100) containing food transported by the transport device (1) and fastens it, a vertical frame (4) that is formed in a vertical direction and supports each device, a support frame (7) that is formed by being supported between the vertical frames (4), an envelope supply device (5) that supplies an envelope (100) containing food supplied from the food stirring supply device (2), an envelope unfolding device (6) that unfolds an envelope (100) supplied from the envelope supply device (5), a scale (9) that measures the weight of an envelope (100) containing food, and a control unit (8) that controls the operation of the food packaging system.

The food packaging system according to the present invention mixes and supplies food from the stirring supply device (2) and places the food in an envelope (100) supplied by the envelope supply device (5), and at this time, the envelope (100) supplied by the envelope supply device (5) is automatically opened by the envelope opening device (6). Then, the envelope (100) containing the food is transported by the transport device (1) and sealed and packaged by the banding packaging device (3). Therefore, the packaging system can automatically perform mixing and feeding of food, supply and opening of the envelope (100), and transportation and packaging of the envelope (100) without a worker, thereby enabling the production and packaging of food to be performed quickly and conveniently.

Since the description of the above-mentioned transport device (1) is as described above, it will be omitted below. For convenience of explanation, the following description will assume that the side where food is fed into the mixing and supply device (2) is one side, and the side where food is discharged from the mixing and supply device (3) is the other side.

The above-mentioned stirring and supply device (2) is configured to stir and transport food and supply it to a bag (100), and includes a transport housing (21) that forms a space in which food is put in, stirred, and transported; and a rotating housing (23) that is rotatably connected to the other side of the transport housing and has a hopper (231) that forms a passage for supplying food to the bag (100).

The above-mentioned transfer housing (21) is configured to form a space in which food is fed, stirred, and fed, so that food is fed to one side and discharged to the other side. In addition, the transfer housing (21) is connected to a rotating housing (23) on the other side, so that food is supplied to a bag (100) through the rotating housing (23). The above-mentioned transfer housing (21) may include a stirring screw (211), a stirring pin (212), a hinged joint (213), a screw rotation motor (214), a protruding end (215), and an inlet (216).

The above stirring screw (211) is configured to mix and transport food within the transport housing (21), and can be formed in the form of a screw that rotates from one side to the other.

The above stirring pin (212) is an additional component to ensure effective mixing of food, and may be formed to protrude on the stirring screw (211). It is preferable that the stirring pin (212) be formed to protrude in the other direction in which the food is conveyed, thereby minimizing damage to the food caused by collision with the food conveyed from one side, while also enabling effective mixing of the food. In particular, the stirring pin (212) may be rotatably coupled to the stirring screw (211), thereby preventing food from getting caught between the stirring pin (212) and the conveying housing (21), scraping the bottom of the conveying housing (21) to ensure mixing, and also preventing damage to the stirring pin (212).

The above hinge joint (213) is configured to rotatably connect the stirring pin (212) to the stirring screw (211), and is preferably formed in one direction of the stirring screw (211) opposite to the direction in which the stirring pin (212) protrudes, so as to reduce damage to food. The hinge joint (213) may include a hinge pin (213a), a fixing member (213b), and an elastic member (213c), as illustrated in FIG. 9.

The above hinge pin (213a) is configured to be rotatably coupled to the stirring screw (211), so that the stirring pin (212) is fixed and the stirring pin (212) also rotates along with the rotation of the hinge pin (213a).

The above fixed member (213b) is configured such that a stirring pin (212) is inserted and fixed and is supported by a stirring screw (211), so that the stirring pin (212) can be stably supported by the stirring screw (211).

The above elastic member (213c) is configured to be inserted between the fixed member (213b) and the stirring screw (211), and is formed of an elastic material so that the fixed member (213b) can rotate at a certain angle due to the elasticity, and accordingly, the stirring pin (212) coupled with the fixed member (213b) can also rotate together.

The above screw rotation motor (214) is configured to rotate the stirring screw (211), and as shown in FIG. 3, can be connected by a gear, belt, etc. to rotate the stirring screw (211).

The above protrusion (215) is configured to protrude upward from a point of the transfer housing (21), and may be formed to form a certain space as shown in Fig. 1. The above protrusion (215) may be formed along the entire length of the transfer housing (21), and forms a space through which food can flow, thereby preventing food mixed and transferred by the stirring screw (211) and the stirring pin (212) from getting caught between the inner walls of the transfer housing (21).

The above-mentioned inlet (216) is configured to form a space for inserting food, and can be formed on the upper side of one side of the transport housing (21).

The above-mentioned rotary housing (23) is configured to be formed in communication with the other side of the transport housing (21) and is rotatably coupled. The above-mentioned rotary housing (23) forms a hopper (231) through which food is supplied to a bag, and the hopper (231) is normally directed upward, but when the bag (100) is opened, it rotates downward to supply food to the bag (100). The above-mentioned rotary housing (23) is supported on a vertical frame (4) to be described later, and is rotatably coupled to the vertical frame (4) by a housing rotation axis (232), as illustrated in FIG. 1. In addition, a first rotation gear (233) is formed in the rotary housing (23) so that the rotary housing (23) rotates by the rotation of the first rotation gear (233), and the first rotation gear (233) is connected to a first housing rotation gear (43) to be described later by a belt so as to rotate according to the rotation of the first housing rotation gear (43). Accordingly, the first rotation gear (233) rotates according to the rotation of the first housing rotation gear (43) which rotates by the movement of the transport mechanism (11), so that the rotary housing (23) automatically rotates according to the movement of the transport mechanism (11), and through this, food can be automatically supplied to the opened bag (100) through the hopper (231) of the rotary housing (23). A detailed description thereof will be described later.

The above banding packaging device (3) is configured to wind and fasten a banding pin (333) around a bag (100) containing food, and seals the bag (100) by fastening the banding pin (333) to the upper part of the bag (100) conveyed by the conveying mechanism (11). The above banding packaging device (3) automatically fastens the banding pin (333) to the bag (100) according to the movement of the conveying mechanism (11), and sequentially lowers and stacks the banding pins (333) in a vertical direction so that continuous fastening of the banding pins (333) is achieved, and by gathering and tightening the upper part of the bag (100) conveyed by the conveying mechanism (11), the fastening of the banding pins (333) is achieved accurately. To this end, the banding packaging device (3) may include a banding fastening portion (31), a banding pin insertion portion (33), an envelope guide portion (35), and a tightening portion (37) as shown in FIGS. 10 to 12.

The above banding fastening part (31) is configured to allow fastening of the banding pin (333) to the envelope (100) and to operate in conjunction with the movement of the transport mechanism (11). To this end, the above banding fastening part (31) may include a banding gear (311), a moving weight (312), and a pulling spring (313).

The above banding gear (311) is configured to rotate in conjunction with the movement of the transport mechanism (11), and is rotated by meshing with the banding gear (113b) of the transport mechanism (11). Accordingly, when the transport mechanism (11) moves forward while holding a bag (100) containing food, and the banding gear (113b) comes into contact with the banding gear (311), the banding gear (113b) also rotates forward along with the forward movement of the transport mechanism (11), and the moving weight (312) is pulled forward according to the rotation of the banding gear (113b). At this time, the banding gear (311) may include a pulling belt (311a) connected to a moving weight (312), and the pulling belt (311a) is pulled according to the rotation of the banding gear (311) to allow the moving weight (312) to move forward.

The above moving weight (312) is configured to move in the forward direction according to the rotation of the banding gear (311), and is supported by being connected to the pulling spring (313). Accordingly, the moving weight (312) pulls the pulling spring (313) as it moves forward, and when the transport mechanism (11) continuously moves forward and the contact between the banding tooth gear (113b) and the banding gear (311) is released, the moving weight (312) moves backward by the restoring force of the pulling spring (313). At this time, the moving weight (312) is formed to have a weight of a certain degree or more so that it can have sufficient acceleration force when pulled by the pulling spring (313). And when the above moving weight (312) is pulled backward by the pulling spring (313), it collides with the banding pin (333) of the banding pin insertion part (33) to be described later, thereby pushing the banding pin (333) backward, and the banding pin (333) pushed backward moves along the banding blade (332) and is wound around and fastened to the envelope (100).

The above-mentioned pulling spring (313) is configured to be connected to the moving weight (312) and pull the moving weight (312), and is pulled in accordance with the forward movement of the moving weight (312). When the contact between the banding gear (113b) and the banding gear (311) is released due to the continuous forward movement of the transport mechanism (11), the moving weight (312) is pulled rearward to collide with the banding pin (333).

The above banding pin insertion portion (33) is configured to insert the banding pin (333) and the banding blade (332) by stacking them in a vertical direction, and as shown in Fig. 12, the insertion rod (331) into which the banding pin (333) and the banding blade (332) are stacked and inserted can be formed in a vertical direction. Accordingly, the banding pin (333) that has been lowered the most is fastened to the envelope (100). The banding pin (333) can be wound around the envelope (100) while being guided by the 'U'-shaped banding blade (332).

The above envelope guide part (35) is configured to guide the movement path of the envelope (100) so that the envelope (100) conveyed by the conveying mechanism (11) is collected, and may include first and second guide rollers (351, 352) that form a certain path on both sides of the envelope (100) as illustrated in FIG. 10. The first and second guide rollers (351, 352) may be formed in multiple numbers along the path along which the envelope is conveyed, and the space between the first and second guide rollers (351, 352) may be formed so that the distance between them becomes narrower as they approach the banding fastening part (31), so that the envelope (100) may be collected thinly in the left and right directions.

The above tightening member (37) is configured to tighten the envelope (100) that is collected by passing through the envelope guide member (35) in the front-back direction to further narrow the cross-sectional area, thereby narrowing the cross-sectional area of the envelope (100) at the point where the banding pin (333) is fastened as much as possible so that the fastening of the banding pin (333) can be performed accurately and smoothly. The above tightening member (37) can be made to operate automatically according to the forward movement of the transport mechanism (11) like the above banding fastening member (31), and to this end, it can include a tightening gear (371) that rotates while meshing with the tightening gear (113c) of the transport mechanism (11) and a pressing member (372) that moves forward according to the rotation of the tightening gear (371) to press the envelope (100).

The above tightening gear (371) is configured to rotate by meshing with the tightening gear (113c) of the transport mechanism (11), and as the transport mechanism (11) moves forward, the tightening gear (113c) rotates forward, and is connected to the pressing member (372) by a belt or the like to move the pressing member (372) forward.

The above pressing member (372) is configured to move forward according to the forward rotation of the tightening gear (371), thereby pressing the envelope (100) forward so that the cross-sectional area of the point where the banding pin (333) is fastened is reduced to the greatest extent possible.

The above vertical frame (4) is formed in a vertical direction and is configured to support each device, and as shown in FIG. 3, it is composed of a plurality of pieces, and a plurality of lower parts are interconnected so that it can be stably erected and maintained in an installed state, and the food mixing and supplying device (2) is installed at the top, the bag supplying device (5) is installed at the rear, and the bag unfolding device (6) is installed at the inside. Accordingly, the vertical frame (4) supports the components of the present invention so that they can be stably installed, and a plurality of gears are installed so that each of the components of the present invention can be mechanically connected and driven.

The above envelope supply device (5) is installed so as to be connected to one of the plurality of vertical frames (4), and is installed so as to be located at the rear side of the other side of the rotary housing (23), and a plurality of envelopes (100) are stored therein, so that when the entrance of the envelope (100) is unfolded and opened, the opened entrance of the envelope (100) can be located at the lower part of the rotary housing (23). As illustrated in FIG. 14, the envelope supply device (5) may include a supply rotation shaft (51) that is rotatably connected at the rear of the connecting frame (41) by penetrating through the upper part, and a plurality of supply standby members (52) that are horizontally protruded and formed at the lower part of the supply rotation shaft (51), and in which a plurality of envelopes are respectively stored.

That is, the envelope supply device (5) of the present invention has a plurality of supply standby members (52) in which a plurality of envelopes (100) are stored, protruding horizontally from the lower portion of the supply rotation shaft (51), so that when all of the envelopes (100) of one of the supply standby members (52) located at the rear of the rotation housing (23) are used up, the supply rotation shaft (51) is rotated so that another supply standby member (52) is located at the rear of the rotation housing (23), thereby reducing the demand for adding envelopes (100) for a long period of time.

At this time, the supply rotation shaft (51) may be configured to further include a handle member (not shown in the drawing) that is extended to the upper portion to facilitate rotation by the worker.

The above supply standby member (52) is configured to include a plurality of connecting arms (521) that protrude horizontally in all directions from the lower portion of the supply rotation shaft (51), a pair of through pins (522) that are connected to the front end of the connecting arm (521) and protrude forward and downward on one side and the other side of the front, a support block (523) in which a plurality of envelopes (100) are stored by penetrating both upper sides of the plurality of through pins (522), and a pressurizing block (524) that is connected so that the pair of through pins (522) are penetrable and movable, and is positioned between the support block (523) and the plurality of envelopes (100).

Since the above support block (523) has a pair of through pins (522) formed in a forward downward direction, a plurality of envelopes (100) are stored by penetrating them, so that the envelopes (100) are naturally supplied in a forward downward direction by the weight of the plurality of envelopes (100), thereby realizing the effect of supplying the envelopes (100) to the rear lower portion of the rotary housing (23).

At this time, the through pin (522) is configured to include a catch cap (522a) that is detachably coupled to the front end to prevent the plurality of envelopes (100) from coming off after the pressurizing block (524) and the plurality of envelopes (100) are installed, and has a step formed on which the envelopes (100) can be caught. It is preferable that the size of the step be formed so that when food is put into the envelope (100) and is caught by the transport mechanism (11) to be described in detail later and then is separated from the through pin (522) and collected, the portion of the envelope (100) caught on the step can be naturally torn and separated.

Since the above pressurizing block (524) may not smoothly move the envelopes (100) in the forward downward direction due to their own weight when a large number of envelopes (100) are used and removed, even if a plurality of envelopes (100) are naturally supplied forward downward by their own weight, it is installed by penetrating the pair of through pins (522) so that the plurality of envelopes (100) are naturally pressed forward as they move forward downward by their own weight, thereby realizing the effect of smoothly supplying them forward downward up to the last envelope (100).

At this time, it will be obvious that the pressurizing block (524) is formed of a material or size that can have a greater weight than the plurality of envelopes (100) so as to be able to sufficiently pressurize the plurality of envelopes (100).

In addition, the pressurizing block (524) is configured to include an envelope protrusion (524a) that is formed to protrude on the front side and is positioned between the pair of through pins (522). It is preferable that the envelope protrusion (524a) is formed to protrude on the center of the front side of the pressurizing block (524). This is to allow the center of the envelope (100), that is, the plurality of envelopes (100), to protrude forward and downward so that only the center of the envelope (100) is gripped by the suction plate (611) of the envelope unfolding device (6), which will be described in detail later, so that the entrance of the envelope (100) can be smoothly unfolded and opened.

In addition, the envelope (100) is characterized in that it includes a contact plate (101) made of a flexible and smooth synthetic resin material on the front upper portion, that is, the front upper portion protruding by the envelope protrusion (524a), and the contact plate (101) enables the suction plate (611) of the envelope unfolding device (6), which will be described in detail later, to be smoothly absorbed, thereby realizing the effect of allowing the entrance of the envelope (100) to be easily unfolded and opened.

In addition, since the pair of through pins (522) are formed in a forward downward direction, the front upper part of the envelope (100) tilts downward, so that the unfolding roller (61) of the envelope unfolding device (6), which will be described in detail later, naturally rotates and can grip the center of the front upper part.

In addition, the envelope (100) is a dedicated envelope used in the automatic food input device of the present invention, and can be formed in various sizes so as to have a length that allows the lower part to touch the scale (9) to be described in detail later and a width according to the amount of food contained therein.

The above envelope unfolding device (6) is installed so that the lower two sides can rotate between a pair of vertical frames (4) among the plurality of vertical frames (4), and is installed so as to be located on the other lower side of the transport housing (21), and when rotated backwards, it grips the upper front side of an envelope (100) located at the front end among the plurality of envelopes (100) so that the upper side of the envelope (100) unfolds and opens, and is elastically supported forward, so that the overall shape is formed in the shape of a "┌┐", and the lower two sides are rotatably hinge-joined to the inside of the vertical frame (4), and when rotated backwards by the transport mechanism (11), the upper center comes into close contact with the upper front side of the envelope (100), so that the upper front side of the envelope (100) is gripped and then rotated forward by elasticity so that the entrance of the envelope (100) unfolds and opens.

At this time, the envelope unfolding device (6) is configured to include an unfolding roller (61) that is rotatably installed at the upper center, i.e., at a position corresponding to the upper front of the envelope (100), and has a plurality of suction plates (611) provided on the outer periphery.

That is, when the envelope unfolding device (6) is rotated backward by the transport mechanism (11), the unfolding roller (61) comes into contact with the upper front surface of the envelope (100), and naturally rotates along the upper front surface of the envelope (100) tilted downward, and the upper front surface of the envelope (100) is wrapped around the unfolding roller (61) by the suction plate (611), thereby rotating forward by elasticity to unfold and open the entrance of the envelope (100).

At this time, a pair of vertical frames (4) on which the envelope unfolding device (6) is installed are configured to include a pair of elastic support blocks (44) that are extended and protruded to the front as shown in FIG. 18, but are extended and protruded so as to be positioned below one side or the other side of the envelope unfolding device (6), and have a support arm (441) formed to protrude upward on the front of the upper surface; and a first spring (45) whose front is coupled to the support arm (441) and whose rear is coupled to one side or the other side of the envelope unfolding device (6), so that the envelope unfolding device (6) is elastically supported forward.

To explain further, the envelope unfolding device (6) of the present invention is connected to the conveying device (11) when the conveying device (11) moves forward and rotates rearward around both sides, and when the conveying device (11) completes moving forward, the connection with the conveying device (11) is released, and is elastically supported forward by the first spring (45) and rotates forward, thereby unfolding and opening the front upper portion, i.e., the entrance, of the envelope (100).

In connection with the above, the spreading roller (61) is provided with a plurality of suction plates (611) on the outer periphery so that the upper front surface of the envelope (100) can be smoothly gripped. When it comes into contact with the upper front surface of the envelope (100), the upper front surface of the envelope (100) is rotated by the upper front surface of the envelope (100) tilted downward, so that the upper front surface of the envelope (100) is gripped by being sucked onto the outer periphery with a wider area.

At this time, the plurality of suction plates (611) are characterized by being formed in a zigzag pattern, and are formed in a zigzag pattern based on the horizontal direction, that is, the longitudinal direction, and the shape of this pattern enables a greater number of the spreading rollers (61) to be provided, and realizes the effect of more stably suctioning and holding the front upper part of the envelope (100).

The above support frame (7) is installed at the bottom between a pair of vertical frames (4) on which the envelope unfolding device (6) is installed, and a transport rail (13) is formed on the upper surface so that the transport mechanism (11) can be installed on the upper side to be able to move forward and backward.

In addition, the support frame (7) of the present invention is configured to include a gear for rotating the rotary housing (23) forward or backward and at the same time rotating the envelope unfolding device (6) backward as the transport mechanism (11) moves forward and backward.

Specifically, the vertical frame (4) located at one end of the plurality of vertical frames (4) is configured to include an unfolding gear (42) rotatably installed on the inner front, and a first housing rotation gear (43) rotatably installed on the inner front, but positioned in front or rear of the unfolding gear (42).

In addition, the support frame (7) of the present invention is configured to include, as shown in FIG. 13, a first gear (71) rotatably installed on the inside, a first linkage gear (73) installed to engage with the lower portion of the first gear (71) and installed on the same axis as the unfolding gear (42), a second gear (72) rotatably installed on the inside, a second linkage gear (74) installed to engage with the lower portion of the second gear (72), and a second housing rotation gear (75) installed to engage with the front or rear of the second linkage gear (74) and installed on the same axis as the first housing rotation gear (43).

At this time, the rotary housing (23) is connected to the first housing rotation gear (43) by a belt, and when the envelope unfolding device (6) rotates backward, the second housing rotation gear (75) rotates, thereby rotating the first housing rotation gear (43), and the first rotation gear (233) is connected to the first housing rotation gear (43) by a belt, thereby rotating forward in a direction opposite to the rotation direction of the envelope unfolding device (6).

That is, since the support frame (7) of the present invention is configured to include a first gear (71), a second gear (72), a first linkage gear (73), and a second linkage gear (74), when the transport mechanism (11) moves forward, the bag unfolding device (6) rotates backward, and the rotating housing (23) rotates forward so that the hopper (231) can be positioned at the bottom, thereby allowing food to be fed into the bag (100).

In addition, the above-mentioned rotary housing (23) is rotated backward by the second housing rotation gear (75) when the above-mentioned transport mechanism (11) moves backward so that the hopper (231) can be positioned at the top, thereby preventing food from being fed into the bag (100) and allowing the upper part of the bag (100) filled with food by the transport mechanism (11) to be gripped.

The operation of the rotary housing (23) and the envelope unfolding device (6) according to the movement of the above-mentioned transport mechanism (11) will be described in more detail. When the transport mechanism (11) moves forward from the lower portion of the rotary housing (23), it is connected to the envelope unfolding device (6) and the rotary housing (23) by a gear and a belt, thereby rotating the envelope unfolding device (6) backward and at the same time rotating the rotary housing (23) forward so that the hopper (231) is positioned downward. After the forward movement is completed, the connection between the envelope unfolding device (6) and the rotary housing (23) is released. When it moves forward from the lower portion of the rotary housing (23), the entrance of one of the envelopes (100) at the lower portion of the rotary housing (23) is unfolded so that the entrance is opened, and at the same time, the hopper (231) of the rotary housing (23) is rotated downward and moved so that the envelope (100) is Allow food to be put in.

The above-mentioned transport mechanism (11) rotates the first gear (71) and the second gear (72) through the floor gear (113a) as it moves forward and backward, which in turn rotates the first housing rotation gear (43) and the unfolding gear (42), and the first rotation gear (233) and the second rotation gear (612) connected to the first housing rotation gear (43) and the unfolding gear (42) by belts, respectively, rotate, thereby rotating the rotation housing (23) and the envelope unfolding device (6).

At this time, when the forward movement of the transport mechanism (11) of the present invention is completed, that is, when the bottom gear (113a) completely passes through the upper portion of the first gear (71) and the second gear (72), the connection between the bag opening device (6) and the rotary housing (23) is released, so that the state in which food is placed in the bag (100) can be maintained.

In addition, when the transport mechanism (11) of the present invention moves backward and moves to the lower part of the rotary housing (23), it is connected to the rotary housing (23) by a gear and a belt to rotate the rotary housing (23) backward so that the hopper (231) is positioned upward, grips the upper part of the bag (100), and when it moves forward again, it detaches the gripped bag (100) from the supply standby member (52), i.e., a pair of through pins (522), so that it can be collected and then packed by the banding packaging device (3).

In other words, when the transport mechanism (11) of the present invention moves backward by the control unit (8), it moves to the lower part of the rotary housing (23), and the bottom gear (113a) rotates the first gear (71) in the reverse direction to rotate the second housing rotation gear (75), thereby rotating the first rotation gear (233) provided in the rotary housing (23) backward to rotate the rotary housing (23) backward, thereby preventing food from being fed in the lower part of the rotary housing (23).

At this time, since the second gear (72) rotates backwards when rotated in the reverse direction and then rotates the envelope unfolding device (6) forward by elasticity, the unfolding gear (42) and the second rotation gear (612) rotate forward again, the rotation shaft on which the second gear (72) and the unfolding gear (42) are installed is configured to include a clutch (not shown in the drawing) installed between the second gear (72) and the unfolding gear (42), and the clutch allows the second gear (72) to rotate in the reverse direction so that the unfolding gear (42) does not rotate when the second gear (72) is rotated in the reverse direction.

The above control unit (8) is configured to control the operation of the food packaging system, and controls the operation of the driving motor (151) to control the forward and backward movement of the transport mechanism (11). As described above, the present invention automatically performs the unfolding of the bag (100), the rotation of the rotary housing (23), and the banding process simply by moving the transport mechanism (11) in the forward and backward direction, so that the operation of the packaging system can be performed only by controlling the operation of the driving motor (151).

Meanwhile, the packaging system is configured to include a scale (9) installed between a pair of vertical frames (4) on which the envelope unfolding device (6) is installed, and installed so as to be in contact with the lower portion of the unfolded envelope (100).

At this time, the control unit (8) of the present invention uses the weight information of the food put into the bag (100) to move the transport mechanism (11) backwards when the food is filled into the bag (100) to match the capacity of the bag (100), to grab the upper part of the bag (100), and then to move it forwards so that it can be collected and packaged by the banding packaging device (3).

That is, the scale (9) transmits the measured weight information to the control unit (8), and when the weight information transmitted from the scale (9) reaches a preset weight, the control unit (8) of the present invention moves the transport mechanism (11) backwards and then forwards again, so that when the bag (100) is filled with food according to its capacity, collection is performed by the transport mechanism (11) and at the same time, the entrance of another bag (100) can be unfolded and opened.

As a result, the food packaging system automatically supplies a bag (100) and simultaneously opens the entrance of the bag (100) so that food is fed into the bag (100), and when food matching the capacity of the bag (100) is fed into the bag (100), it is automatically collected and then packaged, thereby eliminating the hassle of the worker having to repeatedly install or open the bag, allowing the bag (100) to be filled with an appropriate amount of food and then collected and packaged, and preventing the worker's hands or clothing from being contaminated with food, thereby improving hygiene, and enabling the work of feeding food into the bag (100) and collecting and packaging it to be performed continuously, thereby achieving the effect of enabling easy and convenient packaging of food.

In the above, the applicant has described various embodiments of the present invention, but such embodiments are only examples for implementing the technical idea of the present invention, and any change or modification examples that implement the technical idea of the present invention should be interpreted as falling within the scope of the present invention.
