On the other hand, below will be described in more detail by dividing the functions and components of the main part of the food packaging apparatus according to an embodiment of the present invention.

As the packaging film wound on the take-up roller moves to the cut portion, the wrapping film always maintains a constant tension, and it is preferable to retreat about 1 mm after the wrapping film is cut by the cut portion. To this end, the food packaging device is provided with a food packaging film conveying roller resilient device and packaging film reversing device.

12 to 14 is a view of the packaging film reversing device, Figures 15 to 17 is a view of the packaging film conveying roller elastic device.

As a detailed description of the drawings, FIG. 12 is a perspective view of the film rewinder of the individual food packaging device shown in FIG. 1, FIG. 13 is a side view of the film reverser shown in FIG. 12, and FIG. 14 is shown in FIG. Fig. 15 is a schematic view showing that the packaging film is retracted while the tension control lever pivots upward. Fig. 15 is a perspective view of the packaging film conveying roller resilient device of the individual food packaging device shown in Fig. 1, and Fig. 16 is shown in Fig. 15. Side cross-sectional view of the packaging film conveying roller elastic device, Figure 17 is an operating state diagram showing the operating relationship of the packaging film conveying roller elastic device shown in FIG.

12 to 14, the film reverse device 500 is located between the take-up roller 30 and the cut portion 110, the packaging film 31 unwound from the take-up roller 30 is cut portion 110 After cutting by the packaging film 31 operates to retreat by a predetermined length in the direction opposite to the unwinding direction. Such a film reverse device will be described in detail below.

On the other hand, as shown in Figure 15 to 17, the film feed roller resilient device 400 is in a state to maintain a constant tension as the packaging film 31 unrolled from the take-up roller 30 to the cutting portion 110 Adjust the tension of the packaging film 31 to proceed. This film feed roller elastic device will also be described in detail below.

As shown in FIGS. 12 to 14, the film reversing apparatus 500 includes a pulley fixed to the rotation shaft of the second motor 105 and a rotation shaft of the pressure roller 113 positioned above the pair of pressure rollers 113. A tension control lever 301 moving up and down in the vertical direction of the belt 107 connecting the belt 107 and a spring 303 connected to the tension control lever 301 to provide an elastic force so that the tension control lever 301 pivots downward. ), A transfer lever 506 for moving the tension control lever 301 upward, and a link 309 for pivoting the transfer lever 506 by the rotation of the fourth cam 194.

On the other hand, the pivot center point of the tension control lever 301 is a rotation axis of the pressure roller 113 located on the upper side, is fastened to allow relative rotation to the rotation axis of such a pressure roller 113, the tension of the control lever 301 Protruding rods 310H and 310L are formed on the upper and lower surfaces of the inner surface, that is, the belt 107, and the belt 107 is positioned between the upper and lower protrusion rods 310H and 310L. Therefore, when the tension control lever 301 pivots in the upper direction, the lower protrusion bar 310L raises the belt 107 located below the belt 107 to the upper side, and the pressure roller 113 rotates in reverse. 2 When the motor 105 rotates forward, the tension control lever 301 is pivoted downward by the elastic force of the spring 303 having one end fastened to the tension control lever 301 to be positioned above the belt 107. The belt 107 is pressed downward.

And, the transfer lever 506 is located in parallel with the lower plate 20 and the front end is bent to face the tension control lever 301, the rear end to the fastening piece 21 fixed to the upper surface of the lower plate 20 It is hinged and has a fixing piece 307 extending through the lower plate 20 to the lower portion of the lower plate 20 in the middle portion. The link 309 pivoting in contact with the fourth cam 194 is pivoted upward and downward by the pivoting of the fourth cam 194 while being in contact with the fixing piece 307 of the transport lever 506. ) Rotate the up and down direction. In this manner, the tension control lever 301 also rotates in the up and down direction by the tip portion of the feed lever 506 turning up and down. Accordingly, while the tension control lever 301 rotates in the vertical direction by the rotation of the fourth cam 194, the lower protruding rod 310L presses the belt 107 in the upper direction to reversely rotate the pressure roller 113. .

By the reverse rotation of the pressure roller 113, the packaging film 31 is retracted by a predetermined length in the reverse direction of the traveling direction, wherein the retracted length of the lower protrusion rod 310L pushes the belt 107 upwards. It depends on the height you raise.

On the other hand, while the fourth cam 194 is rotated, the link 309 again swings downward, and when the link 309 pivots downward, the feed lever 506 pivots downward by its own load. Accordingly, while the tension control lever 301 also rotates downward by the elastic force of the spring 303, the upper protrusion bar 310H presses the belt downward. Thus, the belt 107 pressed by the upper protrusion bar 310H is subjected to tension, thereby smoothly transmitting the rotation of the second motor 105 to the pressure roller 113.

Therefore, the packaging film 31 wound on the take-up roller 30 by the rotation of the second motor 105 is unwound and then cut by the two cutter blades 111H and 111L of the cutting part 110 and at the same time the fourth cam ( As the pressing roller 113 rotates in reverse by the operation of the film reversing apparatus 500 by the rotation of the 194, the tip portion of the packaging film 31 is reversed by about 1 mm in a direction opposite to the traveling direction thereof.

This is because when the two cutter blades 111H and 111L are operated while the packaging film 31 is not unwound, a part of the tip of the packaging film 31 is cut between the two cutter blades 111H and 111L so that the food is foreign matter. This is to prevent it from being put in.

On the other hand, as shown in Figure 15 to 17, the packaging film conveying roller resilient device 400 is at both ends of the rotating shaft of the pressure roller 113L located in the lower portion of the pair of pressure rollers (113; 113H, 113L) A pair of fixed levers 410, a plate 419 fixed to an upper surface of the lever 410, and a rear end of the lever 410 are connected to move the rear end of the lever 410 downward. It includes a tension spring 420 to provide an elastic force.

Rotating shafts of the pressure rollers 113H located at the upper side of the pair of pressure rollers 113 (113H and 113L) are rotatably fastened to two brackets 401 vertically facing each other of the lower plate 419. . As described above, the belt 107 is fastened to the rotating shaft of the upper pressing roller 113H.

On the other hand, the two levers 410 of the packaging film conveying roller elastic device 400 is hinged to the inner surface of the two brackets 401 facing the center is rotated up and down relative to the hinge axis 417. Then, the rotary shaft of the lower pressure roller 113L is rotatably fastened to the front ends of the two levers 410. In addition, the plate 419 is fixed to the upper surface of the two levers (410). The packaging film 31 is in contact with the upper surface of the plate 419, and proceeds between the pair of pressure rollers 113H and 113L.

On the other hand, one end of the tension spring 420 is fixed to the rear end of the lever 410, the other end of the tension spring 420 is fixed to the bracket 401, respectively. Therefore, the rear end of the lever 410 is always forced to turn downward by the elastic restoring force of the tension spring 420, and the tip of the lever 410 is always turned upward with respect to the hinge axis 417. Get the power to do it.

In this state, when the pressure rollers 113H and 113L rotate for a long time, the pressure rollers 113H and 113L wear, and at this time, the lower pressure roller 113L is moved upward by the elastic restoring force of the tension spring 420. While turning, the pressure roller 113H positioned at the upper side is always in contact with a constant pressure.

Therefore, even when the pressure rollers 113H and 113L are worn and the force pulling the packaging film 31, that is, the tension of the packaging film is weakened, the lower pressure roller 113L is applied to the upper pressure roller by the elastic restoring force of the tension spring 420. Since 113H) is always pressurized to a constant pressure, the tension applied to the packaging film 31 can be kept constant at all times.

On the other hand, after the wrapping film 31 is unwound from the take-up roller 30 by a predetermined length, the unwinding of the wrapping film 31 should be stopped while the rotation of the take-up roller 30 is stopped, while the wrapping film 31 is unwound. Due to the inertia of the take-up roller 30, the take-up roller 30 is not stopped and the packing film 31 is continuously released. To prevent this, the packing film loosening prevention device 500 is installed at the side of the take-up roller 30. do.

18 to 21 are views showing such an anti-loosening device, FIG. 18 is a perspective view showing a packaging film unwinding preventing device of the food packaging device shown in FIG. 1, and FIG. 19 is a packaging film shown in FIG. 18. FIG. 20 is a right side view of the wrapping film loosening prevention device shown in FIG. 18, and FIG. 21 is a schematic view showing an operation relationship of the wrapping film loosening prevention device shown in FIG. 18.

As shown in Fig. 18 to Fig. 21, the film release prevention device 500 is rotated by the inertia of the winding roller 30 is idle rotation when the winding roller 30 of the food packaging device is stopped while rotating. The packaging film 31 is installed to prevent loosening.

The winding roller 30 is located above the lower plate 20. On the upper surface of the lower plate 20, a bracket 505 is erected perpendicularly to the lower plate 20, and the rotation shaft 30a of the take-up roller 30 is rotatably fixed through the upper end of the bracket 505. . A brake drum is disposed at an end portion of the rotation shaft 30a of the take-up roller 30 positioned through the bracket 505, that is, at the end of the rotation shaft 30a positioned on the opposite side of the take-up roller 30 based on the bracket 505. 510 is fixed.

The brake drum 510 has an upper portion thereof wrapped by the brake belt 515, one end of the brake belt 515 being fixed to the bracket 505, and the middle portion of the brake drum 510 along the upper portion of the circumferential surface of the brake drum 510. The other end is extended to the lower portion of the brake drum 510.

Meanwhile, a brake lever 520 having one end hinged to the bracket 505 is positioned below the brake drum 510, and the brake lever 520 pivots upward and downward toward the brake drum 510. The other end of the belt 515 is connected to the stop of 520. Therefore, when the brake lever 520 pivots upward, that is, in the direction of the brake drum 510, the winding roller 30 rotates freely while the brake drum 510 and the belt 515 are spaced apart, but the brake lever 520 is rotated. When turning downward, the upper portion of the circumferential surface of the brake drum 510 and the belt 515 come into contact with each other, and the rotation of the brake drum 510 is stopped by the frictional force.

The other end of the brake lever 520 is fastened so that the upper end of the vertical rod 525 is pivotable. The lower end of the vertical rod 525 is pivotally connected to the rotation shaft 114M of the rear guide roller 115M that moves up and down among the pair of guide rollers 115M and 115F.

The pair of guide rollers 115M and 115F are located at the lower part of the take-up roller 30, and the packaging film 31 released from the take-up roller 30 wraps around the lower part of the guide roller 115M located at the rear and the front thereof. Proceeds to advance while in contact with the upper portion of the guide roller 115M located in front to advance between a pair of pressure roller 113.

Here, the front guide roller 115F is rotatably fixed to the lower end of the bracket 505, the rotating shaft 114F, and the rear guide roller 115M and the long hole 506 formed perpendicular to the bracket 505 Correspondingly located. Then, the rotary shaft 114M of the rear guide roller 115M is located through the long hole (506).

On the other hand, one end of the fixed lever 530 is rotatably fastened to the end of the rotary shaft 114M of the rear guide roller 115M, and the other end of the fixed lever 530 is pivotally fastened to the bracket 505. The upper end of the fixed lever 530 is pivotally fastened to the lower end of the vertical rod 525.

The operation relationship of the film release prevention device configured as described above will be described in detail.

When the packing film 31 located between the pair of pressure rollers 113 proceeds by the rotation of the pressure roller 113, the packing film 31 is tensioned and presses the front guide roller 115F downward. , The rear guide roller 115M is pressed in the upper direction. At this time, the rear guide roller 115M moves upward along the long hole of the bracket 505. While the rear guide roller 115M moves upward, one end of the fixing lever 530 is upper part along the rear guide roller 115M. Will turn in the direction.

As such, when one end of the fixed lever 530 pivots upward, the vertical rod 525 also pivots the other end of the brake lever 520 upward while moving upward. As described above, when the brake lever 520 pivots upward, the belt 515 is spaced apart from the brake drum 510.

The packaging film 31, which is tensioned by the rotation of the pressure roller 113, is released from the winding roller 30 that idles and rotates and passes through the guide rollers 115M and 115F and the pressure roller 113 toward the cutting unit 110.

On the other hand, even if the pressure roller 113 is stopped idle winding roller 30 to release the packaging film 31 by the inertia, the wrapping film 31 located from the winding roller 30 to the rear guide roller 115M. Is in a loose state. At this time, since the tension force of the packaging film 31 does not act on the rear guide roller 115M, it falls down along the long hole 506 of the bracket 505 by the load of the rear guide roller 115M. One end of the fixed lever 530 is turned downward by the falling of the rear guide roller 115M, and the other end of the brake lever is also turned downward by the vertical rod 525.

As such, when the brake lever 520 pivots downward, as described above, the belt 515 presses the brake drum 510 to stop its rotation and winds up by the rotation stop of the brake drum 510. Rotation of the roller 30 is stopped.

Therefore, the rotation of the take-up roller 30 is stopped almost at the same time as the rotation stop of the pressure roller 113, whereby the packing film 31 can be prevented from being unwound from the take-up roller 30.

On the other hand, it will be described in more detail with respect to the cut portion in the food packaging apparatus of the present invention.

22 is a detailed view of the cutting part shown in FIGS. 5A and 5B, FIG. 23 is a plan sectional view of the cutting part shown in FIG. 22, and FIG. 24 is a view for explaining the operation relationship of the cutting part shown in FIG. 22. This is a working state diagram.

As shown in Figs. 22 to 24, the two cutter blades 111H and 111L are positioned in the X shape like general scissors. Brackets 117H and 117L are fixed to the outside of the rear ends of the two cutter blades 111H and 111L, and one ends of the cranks 116H and 116L are respectively fastened to the lower surfaces of the brackets 117H and 117L. One end of the cranks 116H and 116L is fastened to the rear of the lever point 120 to the brackets 117H and 117L fixed to the lever, and the lever point 120 to the bracket 117L fixed to the lower cutter blade 111L. One end of the crank 116L is fastened in front of the. Therefore, when the two cranks 116H and 116L move upwards, the tip portions of the two cutter blades 111H and 111L in which the blades are formed are cut in a direction facing each other while cutting the packaging film 31 positioned therebetween, When the cranks 116H and 116L move downward, the two cutter blades 111H and 111L are opened to each other.

On the other hand, the central axis 121 located at the lever point 120 of the cut portion 110 is located through the two brackets (117H, 117L) and two cutter blades (111H, 111L). And, one end of the central shaft 121 is fixed to the support 124, where the support 124 is fixed to the wall 119 for fixing the pressure roller 113. The compression spring 122 surrounds the circumference of the central axis 121, and the stopper 123 is fixed to the end of the central axis 121 to be in contact with the end of the compression spring 122. Therefore, the elastic restoring force of the compression spring 122 is applied to the two cutter blades 111H and 111L located between the compression spring 122 and the support 124, and the two restoring forces are caused by the elastic restoring force of the compression spring 122. The blades 111H and 111L are in close contact with each other. More preferably, protrusions 125 are formed in the rear end of the upper cutter blade 111H among the two cutter blades 111H and 111L to which the brackets 117H and 117L are fixed. The projecting portion 125 is a packaging film while the two cutter blades (111H, 111L) in the cutting operation, the portion where the two cutter blades (111H, 111L) are in contact with each other along the cutter blades (111H, 111L) to the tip. 31) is formed for easy cutting.

Meanwhile, the other ends of the two cranks 116H and 116L fastened to the two brackets 117H and 117L are rotatably fastened to one fixing piece 126, and the fourth end of the driving shaft 180 is fixed to the fixing piece 126. The link 118 connected to the fourth link 204 in contact with the cam 194 is fixed. The upper end of the link 118 is formed in a shape such as 'T', and one end of the upper horizontal part is fixed to the fixing piece 126. It is fixed, and the other end of the horizontal portion is rotatably fastened to the fixing rod 127 fixed to the wall 119 for fixing the pressure roller 113.

Therefore, when the link 118 is moved upward by the rotation of the fourth cam 194 of the drive shaft 180, one end of the horizontal portion of the link 118 is raised, and the fixing piece 126 is also raised. The cranks 116H and 116L are also raised so that the two cutter blades 111H and 111L cut the packaging film 31 positioned therebetween, and the link 118 is lowered by the rotation of the fourth cam 194. When moving to the two cranks (116H, 116L) is also lowered while the two cutter blades (111H, 111L) are turning in a direction that is mutually open around the central axis (121) which becomes the lever point (120).

In addition, since the two cutter blades 111H and 111L are positioned to interfere with each other, in the process of cutting, the points of contact between the cutter blades 111H and 111L move in the tip direction of the cutter blades 111H and 111L. There is a gap between the rear ends. When the two cutter blades 111H and 111L are opened to each other by the rotation of the fourth cam 194, the point where the two cutter blades 111H and 111L are in contact with each other moves to the rear of the cutter blades 111H and 111L. At this time, the rear ends of the two cutter blades 111H and 111L are in close contact with each other by the elastic restoring force of the compression spring 122, and the tip ends of the two cutter blades 111H and 111L are opened.

It is up to the level of the through-hole 11 formed in 10, and the lowest position is located in a lower part.

The winding roller 30 is positioned on the upper plate 10, and the wrapping film 21 unwound by the winding roller 30 is guided by a pair of guide rollers 115 and two cutter blades of the cutting unit 110. Proceed between (111H, 111L). In the advancing direction of the packaging film 31, a pair of pressure rollers 113 are located behind the two cutter blades 111H and 111L, and the packaging film 31 compressed to the pressure roller 113 is a pressure roller. By rotation of 113, it advances between two cutter blades 111H and 111L. A pulley is fixed to an end of one of the press rollers of the press roller 113, and the pulley is connected to the pulley fixed to the rotation shaft of the second motor 105 by the belt 107.

Therefore, the packaging film 31 wound on the winding roller 30 by the rotation of the second motor 105 is released. On the other hand, the pressing member 109 is located in the upper middle of the belt 107 connecting the second motor 105 and the pressing roller 113, the vertical movement of the belt 107, the pressing member 109 Presses the middle portion of the belt 107, the pressing roller 113 is connected to the second motor 105 to rotate the packaging film cut by the two cutter blades (111H, 111L) while rotating in a predetermined angle ( The tip of 31) is moved backward by about 1mm. Therefore, even when the two cutter blades 111H and 111L perform the cutting process in a state where the packaging film 31 does not proceed, the front end portion of the packaging film 31 is cut to generate foreign substances of the packaging film 31 having the same size as the yarn. I never do that. The pressing member 109 is connected to the fourth link 204 that is pivoted by the fourth cam 194 of the drive shaft 180.

10A and 10B, the horizontal transfer unit 50 is installed on the upper surface of the upper plate 10.

The third slide bundle 57 is connected to the lower link, and moves along the long hole formed in the upper plate (10). The long hole is formed parallel to the guide rod 55 in the middle of the pair of guide rods 55. Accordingly, the push member 59 pushes the food 1 in one direction while the third slide 57 moves in the direction in which the food 1 raised upward through the through hole 11 of the upper plate 10 is located. And the food (1) is pushed by the push member 59 is guided by a pair of guide bar 51 while being pushed out of the upper plate 10 is discharged. On the other hand, the link connected to the third slide bundle 57 of the horizontal transfer unit 50 is reciprocated by a predetermined distance by the turning of the first link 201 in contact with the first cam 191.

Then, the folding portion 150 is a length folding plate 151 for folding the packaging film 31-1 surrounding the upper and side surfaces of the food 1 in the longitudinal direction from the lower surface of the food 1, and the food 1. The width folding plate 161 is folded in the width direction.

As shown in FIGS. 8A and 8B, the length folding plate 151 reciprocates in the longitudinal direction of the food 1 with respect to the food 1 transported upward through the through hole 11 of the upper plate 10. It is a pair plate to move. The pair of longitudinal folding plates 151 are positioned perpendicular to the guide bar 51 with respect to the food 1 and are located symmetrically with each other, and at the same time reciprocate toward the food 1.

On the other hand, the food 1 located in the upper portion of the through hole 11 of the upper plate 10 by the upper rod 71 and the lower rod 91 is a packaging film ( 31-1) because the area of the packaging film 31-1 wraps the upper and side surfaces of the food 1, the edge of the packaging film 31-1 does not completely penetrate the through hole 11. It is located at the bottom of the upper plate (10). Therefore, in this state, when the length of the folding plate 151 enters between the food 1 and the upper plate 10, the packaging film 31-1 has both sides of the food 1 in the lengthwise direction of the food 1. Wrapped in.

This length folding plate 151 has a structure that can be inserted into the cutout formed in the head 92 of the lower rod (91). That is, a locking jaw 42 having the same shape as the locking jaw 42 of the fastening piece 43 fixed to the lower surface of the rotating plate 40 is formed and inserted into the cutout formed in the head 92 of the lower rod 91. do.

In addition, a pair of guide rods 155 fixed in the moving direction of the length folding plate 151 are positioned perpendicular to the guide bar 51. Here, the guide rods 155 for guiding the pair of length folding plates 151 are four in total. As described in the horizontal transfer unit 50, the fourth slide bundle 157 moving along the guide rod 155 is positioned, and the length-folding plate 151 is fixed to the lower surface of the fourth slide bundle 157. . A link is connected to a lower surface of the fourth slide bundle 157 through a long hole formed in the upper plate 10 in the moving direction of the length-folding plate 151, and the link is connected to the rotation of the second cam 192. It is connected to the second link 202 acting along the reciprocating motion of the pair of length plates 151 in the direction of the food or vice versa.

Meanwhile, as illustrated in FIGS. 9A and 9B, the width folding plate 161 is installed on the pair of guide rods 55 of the horizontal transfer unit 50 described above. The width contact plate 161 is fixed to the lower surface of the fifth slide bundle 167 that moves along the pair of guide rods 55 of the horizontal transfer unit 50. The lower surface of the fifth slide bundle 167 is connected to the third link 203 which is operated by the rotation of the third cam 193. Since the width folding plate 161 operates after the length folding plate 151 is operated, the wrapping film 31-1 folds the lower surface of the food 1 in the width direction while folding the lower surface of the food 1. As described above, the food 1 folded in the width direction of only one side of the side where the width folding plate 161 is located has the food 1 along the guide bar 51 by the operation of the horizontal transfer part 50 which is the next step. While moving, the packaging film 31-1 covers the lower surface of the food 1 in the width direction of the other side.

On the other hand, the heating unit 130 is located between the guide bar 51. As described above, the packaging film 31-1 of the folded portion of the food 1 is folded and bonded in the width and length directions while passing through the heating unit 130.

And, the pressure bar 53 is located in the upper portion between the guide bar 51. It is preferable that the height of the pressure bar 53 and the lower heating part 130 is generally lower than the thickness of the food 1. The reason is that the food (1) pressurized by the pressure bar 53 to pressurize the packaging film (31-1) located between the heating unit 130 and the food (1) so that fusion can be easily made to be.

Then, the food 1 transferred to the one end of the upper plate 10 by passing through the heating unit 130 by the horizontal transfer unit 50 to fall to the outside of the upper plate 10 along the guide plate 13. do. A storage box is positioned below the guide plate 13 to accommodate the packaged food 1.

It will be described in detail the operation relationship of the food packaging device configured as described above.

When the power switch 5 is turned on in the control box 4, the drive shaft 180 is rotated by the rotation of the first motor 101, and six cams 191 are rotated by the rotation of the drive shaft 180. ˜196 all rotate at the same time, and the first bevel gear 45 rotates. Rotation of the first bevel gear 45 rotates the rotating plate 40 through the second bevel gear 182 and the rotating shaft 44.

As the rotating plate 40 rotates, the food 1 seated in the hole 41 of the rotating plate 40 passes through the lower part of the optical sensor 210, and the optical sensor 210 moves into the hole 41 of the rotating plate 40. ) Detects whether food 1 is located. The signal is then input to the control box (4). In the control box 4, when a signal from the optical sensor 210 is input, the second motor 105 is driven to rotate the pressure roller 113, and the wrapping film 31 is wound from the winding roller 30 by a predetermined length. Let loose. The unwrapped packaging film 31 is guided by the guide roller 115 so as to pass through between the upper and lower cutter blades 111H and 111L of the cutting unit 110 to come out at the upper portion of the hole 41 of the rotating plate 40. do.

In this state, the operation sequence of the links 201 to 206 in contact with the six cams 191 to 196 of the driving shaft 180 is as follows.

First, as shown in FIG. 11, the fourth link 204, which is in contact with one rotation of the fourth cam 194, is wrapped while moving while moving the upper and lower cutter blades 111H and 111L of the cut portion in contact with each other. The film 31 is cut | disconnected, and the upper and lower cutter blades 111H and 111L are located in mutually spread state again. Secondly, the sixth link 206, which is in contact with the sixth cam 196, pivots to lower the upper rod 71. At this time, the upper rod 71 passes through the through hole 11 of the upper plate 10 to press the upper portion of the food (1) on which the packaging film 31-1 is seated. Thirdly, the fifth link 205, which is in contact with the fifth cam 195, is turned to raise the lower rod 91. At this time, the lower rod 91 and the upper rod 71 for pressing the food 1 rises at the same speed at a constant speed. As the lower rod 91 and the upper rod 71 ascend at the same speed as described above, the packaging film 31-1 located between the head 92 of the lower rod 91 and the lower end of the upper rod 71 and its The lower food 1 penetrates the through hole 11 of the upper plate 10 and is positioned on the upper surface of the upper plate 10. At this time, since the cut area of the packaging film 31-1 is larger than that of the through hole 11, the edge of the packaging film 31-1 is caught by the edge of the through hole 11. Then, when the upper rod 71 is located at the highest point of the stroke, the second link 202 contacting the second cam 192 is turned, and the pair of lengthwise plates 151 are moved by the food 1. Move in the direction of location. Then, the length folding plate 151 is advanced between the lower surface of the food 1 and the head 92 of the lower rod 91 to fold the packaging film 31-1 in the longitudinal direction. Then, while the length folding plate 151 folding the packaging film 31-1 retreats, the operation of the width folding plate 161 proceeds in a state in which both length folding plates 151 are distant from each other.

The operation relationship of the widthwise folding moves the width folding plate 161 in the direction in which the food 1 is located while the third link 203 that is in contact with the third cam 193 turns. Then, the width folding plate 161 is advanced between the lower surface of the food 1 and the upper end of the upper rod 71 to fold the edge of the width direction of the packaging film 31-1 to cover the lower surface of the longitudinally folded portion. do. Then, the width contact plate 161 moves backward.

As such, after the packaging film 31-1 is folded in the width direction, the horizontal transfer unit 50 operates.

In the operation of the horizontal transfer unit 50, the horizontal transfer unit 50 operates while the first link 201 that is in contact with the first cam 191 rotates. The horizontal transfer unit 50 pushes the food 1 wrapped by the packaging film 31-1 between the guide bars 51 while moving in the direction in which the width receiving plate 161 operates. The upper surface of the food 1 pushed and moved by the horizontal transfer unit 50 moves along the pressure bar 53 installed lower than the height of the food 1, and the food 1 is lowered by the pressure bar 53. Is pressed in the direction. As described above, the food 1 passes through the heating part 130 while moving along the pressure bar 53. The packaging film 31-1 folded on the bottom surface of the food 1 by the temperature of the heating part 130 is Fusion.

Then, the packaging film 31-1 fused while passing through the heating unit 130 falls down along the guide plate 13 installed at the side of the heating unit 130.

At this time, since the packaging film 31-1 is wider than the area of the through hole 11, the packaging film 31-1 wraps the upper and side surfaces of the food (assuming a food cube). In this state, both of the lengthwise folding plate 151 enters between the food 1 and the head 92 of the lower rod 91, so that the packaging located in the longitudinal direction of the food 1 among the edges of the packaging film 31-1. The edge of the film 31-1 folds the bottom surface of the food 1 in the longitudinal direction.

Then, as a next step, the width folding plate 161 enters between the food 1 and the head 92 of the lower rod 91, so that the width of the food 1 in the width direction of the food 1 in the edge of the packaging film 31-1. The edge (part opposite to the width plate) of the packaging film 31-1 located in the folded direction folds the bottom surface of the food 1 in the width direction. Then, the horizontal transfer unit 50 moves the packaged food 1 in the direction of the heating unit 130 while moving in the direction of the food 1. In this transfer process, a portion of the packaging film 31-1 located in the through hole 11 of the upper plate 10 (a portion opposite to the width plate) is moved by the food 1 and the width plate 161. It is folded to the lower surface of the other part of the edge (the opposite side of the portion facing the width plate) of the packaging film 31-1 contacted by.

According to this folding order, the upper and side surfaces of the food 1 are sealed by the packaging film 31-1, and the lower surface of the food 1 covers four directions, that is, both ends of the length of the food 1.
