Description

Weighing packaging device for granular products {PACKING DEVICE FOR GRANULE}

The present invention relates to a device for measuring and packaging granular products into packaging bags.

Generally, a certain amount of grains such as rice or beans are put into a packaging pack, the top inlet of the pack containing the grains is sealed, and then sold as a product. Therefore, it is easy to move and carry the grain pack product, and it can be easily opened and used when necessary.

A pack product packaging machine for packaging grains in these packaging packs supplies packaging packs to the packaging machine main body, injects a certain amount of grain through the upper inlet of the packaging pack supplied to the packaging machine main body, and then uses a heater to There is a device that hot seals (top seals) the upper inlet part of the packaging pack and then cools and dries the hot sealing part for a certain period of time. In other words, the pack product packaging machine injects grains into the upper inlet of the packaging pack for a certain period of time after the packaging pack is supplied, and when the filling of grains into the inside of the packaging pack is completed after a certain period of time, the grain is again fed into the upper inlet of the packaging pack for a certain period of time. After hot-sealing the part, the hot-sealed part of the packaging is cooled for a certain period of time to produce a pack containing grains.

However, in the case of a conventional pack product packaging machine, as described above, the time required to supply the packaging pack (mainly, meaning a plastic packaging bag) to the packaging machine main body and then input the grain through the upper inlet of the packaging pack until the filling is completed. Because the waiting time (pause time) is prolonged during each process, such as waiting for the process such as waiting for the grain to be hot-sealed, the productivity per unit time increases. There is a problem with this deterioration. That is, in the case of a conventional pack product packaging machine, the idle time (idling time) is greatly increased in each process such as the packaging pack input process, grain input process, filling process, and hot sealing process, resulting in a decrease in productivity per unit time. There is this. In other words, you have to wait a certain amount of time until the filling is complete after putting grain into the packaging pack, and even after putting grain in the packaging pack, you have to wait a certain amount of time to hot seal the top inlet of the packaging pack, and cool the hot sealing part. Since you have to wait a certain amount of time for this, the pause time during the production of pack products increases significantly during the entire process, and as a result, the productivity of pack products inevitably decreases.

For the same reason, some components are exaggerated, omitted, or schematically shown in the accompanying drawings.

1 is a block diagram illustrating a weighing and packaging device for granule products according to an embodiment of the present invention.

Referring to FIG. 1, the measuring and packaging device 1000 for granular products includes a packaging bag supply unit 100, a measuring unit 200, a sealing unit 300, a packaging unit 400, a first moving unit 500, and a first moving unit 500. 2 Includes a moving part (600).

The packaging bag supply unit 100 withdraws the packaging bag P in units of one sheet. The packaging bag P is in the form of a pouch made of synthetic resin material to accommodate granular products (for example, items such as grains, feed, etc.).

Figure 2 is a schematic perspective view of a packaging bag applied to the present invention. As shown, the packaging bag (P) is applied to the present invention in that both sides are folded in a ∑ shape to increase the carrying capacity. However, the form shown in Figure 2 is only one of applicable packaging bags and is not limited to the form shown. Packaging bags that are not folded on both sides (i.e., open) can also be used in the weighing and packaging device 1000 for granular products.

The weighing unit 200 puts the product (R) into the packaging bag (P) according to the set weight. In the present invention, the weighing unit 200 does not measure the product (R) in advance before putting it into the packaging bag (P), but measures the change in weight of the packaging bag (P) in real time during the process of putting the product (R) into the packaging bag (P). Weighing is performed in this way.

The sealing unit 300 seals the packaging bag (P) into which the product (R) has been completely inserted. Sealing is performed by heat fusion method.

The packaging unit 400 puts the sealed packaging bag (P) into the box (B).

The first moving unit 500 moves the packaging bag (P) into which product input has been completed in the measuring unit 200 to the sealing unit 300.

The second moving unit 600 moves the packaging bag P that has been sealed in the sealing unit 300 to the packaging unit 400.

Figure 3 is a physical photograph of the packaging bag supply unit according to one embodiment, Figure 4 explains the continuous operation of the packaging bag supply bag shown in Figure 2, and Figure 5 explains the process of handing over the packaging bag to the weighing unit. The state shown in FIG. 3 is the process progressing from (B) to (C) in FIG. 4.

Referring to FIGS. 3 to 5 , the packaging bag supply unit 100 includes a tray 110, an adsorption unit 120, a horizontal support bar 130, and a first grip 140.

The tray 110 is for continuously supplying packaging bags (P) and accommodates a plurality of stacked packaging bags.

The adsorption unit 120 separates and withdraws the packaging bags located at the top of the packaging bags accommodated in the tray 110, one by one.

In this embodiment, the suction unit 120 has a form including a plurality of suction plates 121 and a drive unit 122 that elevates the suction plates 121 and advances them in the extraction direction. However, this is only one of the possible forms, and the configuration corresponding to the adsorption unit 120 varies depending on the material and characteristics of the packaging bag P used (for example, pushing and withdrawing one sheet at a time using the rotation of a roller). It is also possible to implement it in the desired way.

When the drive unit 122 descends from the standby position to the tray 110, the suction plate 121 applies negative pressure to attach the packaging bag P ((A) of FIG. 4), and then rises to attach the suction plate 121 to the tray 110. ), separate the packaging bag (P) attached from the stacked pile, move forward, and position the open end of the packaging bag (P) at the portion where the first grip 140 is located ((B) in Figure 4).

The first grip 140 is in the form of a pair of opposing tongs, and grabs both ends of the open side of the packaging bag P pulled out by the suction unit 120 and transfers it to the weighing unit 200.

The horizontal support bar 130 supports the lower ends of the open side of the packaging bag (P) so that the first grip 140 can reliably grip both ends of the open side of the packaging bag (P).

The horizontal support bar 130 is in a position corresponding to the bottom surface of the tray 110 in the standby state, and then the adsorption unit 120 withdraws the packaging bag (P) and packs it in the area where the first grip 140 is located. When positioning the open end of the bag (P), it rises to the position of the clamp surface of the first grip 140 (FIG. 3).

The packaging bag (P) applied to this embodiment has both sides folded in a ∑ shape, and the sucker 121 is attached only to the upper side of the packaging bag (P), so the ∑ shaped folded portion may be opened due to gravity, etc.

The horizontal support 130 prevents the packaging bag (P) from opening and allows the first grip 140 to reliably grip both ends of the packaging bag (P). That is, if there is no horizontal support 130, problems such as the first grip 140 gripping only the upper part of the ∑-shaped folded portion may occur.

When the first grip 140 grips the packaging bag P ((C) in FIG. 4), the suction plate 121 releases the negative pressure, breaks away from the packaging bag P, and moves to the standby position for the next operation. .((D) in Fig. 4, (A) in Fig. 5)

The first grip 140 includes a pair of tongs (141L, 141R) arranged in a width corresponding to the horizontal width of the packaging bag (P) and a rotating arm (142L, 142R) having the tongs (141L, 141R). do.

The rotation arm (142L, 142R) has an end opposite to the end where the tongs (141L, 141R) are fixed to the rotation axis (Y), and the tongs (141L, 141R) are rotated 90° in the withdrawal direction to hold the packaging bag ( The packaging bag (P) is handed over to the weighing unit 200 so that the open end of P is facing upward based on the direction of gravity. ((B) to (D) of FIGS. 5) For reference, ((B) to (D) of FIG. 5) D) corresponds to (A) in Figure 4 in the next repeated task.

The weighing unit 200 includes a second grip 210, an open sucker 220, a hopper 230, and a load cell 240. The second grip 210, the open sucker 220, the hopper 230, and the load cell 240 are disposed on the upper surface of the frame (F) forming the weighing and packaging device 1000 for granule products.

The second grip 210 is in the form of a pair of opposing grips, and holds and secures both ends of the top (i.e., open side) of the packaging bag P taken over from the first grip 140.

The first grip 140 is designed to avoid interference with the second grip 210 and to secure the packaging bag (P) in consideration of the part that the second grip 210 will hold when withdrawing the packaging bag (P) from the tray 110. Hold the bottom slightly rather than the end, leaving a portion of the packaging bag (P) that the second grip 210 can hold.

The open suction plate 220 opens both sides of the open portion of the packaging bag (P) to form a passage through which the product is introduced. The end of the packaging bag (P), which is in close contact with the opening suction plate 220, is opened by opening the bag. At this time, the second grip 210 moves to narrow the gap.

The hopper 230 puts the product into the open passage of the packaging bag (P).

The load cell 240 measures the weight of the product put into the packaging bag (P) by measuring the force applied to the second grip 210. When the measured weight reaches the desired value, the hopper 230 is closed and weighing is completed. At this time, the second grip 210 returns the narrowed gap to its original position.

The packaging bag (P) into which the product (R) has been completely inserted is moved to the sealing unit (300) by the first moving unit (500).

Figure 7 is a physical photograph showing the first moving part, and Figure 8 explains the operation of the first moving part. Figure 7 shows a state waiting for weighing, and Figure 8 (A) shows a state in which the third grip 530 has advanced to grab and fix both ends of the packaging bag P. (C) in FIG. 8 shows the state in which the sealing unit 300 has been moved to its position.

The first moving part 500 includes a moving body 510, a first stand 520, a third grip 530, a rail 540, and a contact bar 550.

The moving body 510 reciprocates between positions where the metering unit 200 and the sealing unit 300 are disposed along the rail 540.

The third grip 530 is disposed on the moving body and holds and secures both ends of the packaging bag (P) when the weighing unit 200 completes inserting the product into the packaging bag (P).

Specifically, the first support 520 is in the form of going up and down (up and down reciprocating) along the moving body 510, and when the input of the product is completed in the weighing unit 200, it rises to support the lower side of the packaging bag.

At this time, in order to assist the grip force of the third grip 530, the first stand 520 rises to support the packaging bag (P) from below, and then the third grip 530 advances and performs a grip operation to produce the packaging bag ( Both ends of P) are fixed (Figure 8(B)), and then the moving body 510 moves to move the packaging bag P. Since the first stand 520 supports the packaging bag (P), stable movement is possible even when the weight to be weighed is high.

Figure 9 is an actual photograph of the sealing part. Specifically, it is in the direction from the weighing department to the packaging department.

The sealing unit 300 includes a fourth grip 310, a second support 320, and a heating press 330.

The heat presser 330 heat-compresses and seals both sides of the packaging bag (P). It is in the form of a heating bar arranged on the left and right based on the shown standard. The portion of the packaging bag (P) that the heating press 330 touches is melted and sealed.

The sealing unit 300 performs a two-stage operation when heat fusion is performed by the heat press 330 to prevent wrinkles from occurring in the sealed portion of the packaging bag P. Due to the volume and weight of the product (P) put into the packaging bag (P), wrinkles occur if there is no pulling action.

The fourth grip 310 is in the form of a pair of tongs and holds and secures both ends of the packaging bag P that has been moved. At this time, as a preparatory operation to prevent wrinkles from forming in the packaging bag P, the fourth grip 310 grips the pair with the gap between them narrowed. (Figure 11 (A))

The heating press 330 includes a pair of heating bars (331L, 331R) and a pair of temporary fixing bars (332L, 332R).

A pair of temporary fixing bars (332L, 332R) protrudes toward the packaging bag (P) rather than a pair of heating bars (331L, 331R), and a pair of heating bars (331L, 331R) protrude from the packaging bag (P). Before touching, the temporary fixing bars (332L, 332R) first secure both sides of the packaging bag with light pressure. In this state, the upper end of the packaging bag (P) held by the fourth grip 310 is pulled tightly in the width direction to remove wrinkles in the area where the heating bars (331L, 331R) will face each other. Next, the heating bars 331L and 331R are brought into close contact with each other to achieve sealing. (Figure 11(B))

When the movement of the packaging bag (P) is completed, the second support 320 rises and supports the lower side of the packaging bag.

In order to prevent the sealing portion from stretching due to the weight of the weighed product (R), the second stand 320 is raised to a set height (second height) before the operation of the heating press 330 is performed and the packaging bag (P ) supports the lower side of the

The second height is a height at which the weight of the product (R) put into the packaging bag (P) is fully supported by the second stand (320), and the height at which the first stand (520) supports the lower surface of the packaging bag (P) It is preferable that the position is higher than the first height.

The sealing unit 300 may further include a contact bar 340 that presses both sides of the packaging bag (P) to expel air in order to prevent the volume from increasing due to unnecessary air when sealing the packaging bag (P). there is. In this embodiment, the contact bar 340 is in the form of a pair of left and right sides, one of which is located in the structure where the second pedestal 320 is placed, and the other side of the contact bar 550 is located in the moving body 510.

The second stand 320 stands by at a position lower than the first height, and when the first stand 520 moves the packaging bag P, it rises to the second height and supports the lower side of the packaging bag P.

At this time, so that the second pedestal 320 can pass through the first pedestal 520 and rise, the second pedestal 320 and the first pedestal 520 each have a comb shape with parallel comb blades. It is desirable to have it. In this form, the blades can pass through each other without interference.

The sealing unit 300 further includes an air injection port 350 that sprays air to cool the sealed portion in order to quickly proceed with the next operation. The second stand 320 supports the packaging bag P until the next operation, and cooling of the sealed portion is performed.

The second moving unit 600 moves the packaging bag P that has been sealed in the sealing unit 300 to the packaging unit 400.

The second moving part 600 includes an upper rail 610 that moves the fourth grip 310. Since the packaging bag (P) is moved by the fourth grip 310, the fourth grip 310 can also be viewed as a component of the second moving unit 600 from the viewpoint of operation.

When sealing of the packaging bag (P) by the heating press 330 is completed, the second stand 320 is lowered to the standby position, and the packaging bag (P) is hung on the fourth grip 310 while hanging on the upper rail 610. ) moves to the position of the packaging unit 400.

The operation of the sealing unit 300 will be described in more detail with reference to FIGS. 12 and 13.

(A) Move to the position of the seal (300)

The packaging bag (P) in which the product (R) has been completely inserted into the measuring unit (200) is moved to the sealing unit (300) by the first moving unit (500). The first support 520 supports the packaging bag (P) from below, and the third grip 530 grips and fixes both ends of the packaging bag (P) so that the packaging bag (P) is attached to the sealing portion (300). Located.

(B) Operation of the fourth grip 310

The fourth grip 310 is in the form of a pair of tongs and holds and secures both ends of the packaging bag P that has been moved (grip operation). At this time, as a preparatory operation to prevent wrinkles from forming in the packaging bag P, the fourth grip 310 grips the pair at a distance of “1”.

In the schematic illustration, the fourth grip 310 appears to be lowered, but this means a grip action. In operation (a), the packaging bag (P) is entered so that its upper end is located in the open gap of the fourth grip (310).

At the same time that the fourth grip 310 performs the closing operation (grip operation), the third grip 530 unfastens both ends of the packaging bag P and returns to the standby position.

(c) Air discharge

The contact bars (340, 550) advance to exhaust the air inside the packaging bag (P). At this time, at the same time, the second stand 320 rises to the second height to support the lower side of the packaging bag.

(D) Interval expansion operation of the fourth grip 310

As an operation to remove wrinkles from the packaging bag (P), the fourth grip 310 expands the gap between the pair to a “gap 2” state.

The purpose of expanding the fourth grip 310 from “Gap 1” to “Gap 2” is to smooth out wrinkles in the area where the heating press 330 is in contact, and to prevent the packaging bag (P) from being deformed by excessive expansion. To do this, the gap between the fourth grips 310 is within the set tension. In this embodiment, the spacing of the fourth grip 310 is adjusted by air pressure injection, and when the wrinkles in the “interval 1” are small, the wrinkles are extended only to the distance where the wrinkles are straightened. Since the gap adjustment mechanism of the fourth grip 310 is injected with pneumatic pressure to expand to “gap 2”, when the fourth grip 310 is opened in step (e), the gap is expanded to “gap 2”.

For reference, “interval 2” is the interval between the pair of fourth grips 310 located at both ends of the packaging bag (P) based on the cross section, that is, at the ∑-shaped folded portion. The fourth grip 310 moves the sealed packaging bag P to the packaging unit 400, so that the 4-layer part is gripped to prevent deformation due to weight.

(E) Operation of the heating compressor 330

The heating press 330 includes a pair of heating bars (331L, 331R) and a pair of temporary fixing bars (332L, 332R). First, the temporary fixing bars (332L, 332R) are in close contact with both sides of the packaging bag (P). The temporary fixing bars (332L, 332R) are made of an elastic sponge material and have a shape that protrudes more than the heating bars (331L, 331R).

When the temporary fixing bars (332L, 332R) come into contact with both sides of the packaging bag (P), the fourth grip (310) is opened. As the fourth grip 310 opens, the gap between the fourth grips 310 expands to “gap 2”.

Since the temporary fixing bars (332L, 332R) hold both sides of the packaging bag (P), the tension is maintained even when the fourth grip (310) is open.

Subsequently, the fourth grip 310 is closed again, and the heating press 330 advances further so that a pair of heating bars 331L and 331R come into contact with both sides of the packaging bag P to achieve sealing by melting.

When sealing is completed, the heat press 330 breaks the close contact and returns to its original position, and the air nozzle 350 cools the sealed portion while the second support 320 supports the packaging bag P until the next operation. This is done.

When cooling is completed, the second stand 320 is lowered to the standby position, and the packaging bag (P) moves to the position of the packaging unit 400 along the upper rail 610 while hanging on the fourth grip 310. .

Figures 14 and 15 are actual photos of the packaging part. The packaging unit 400 includes a third stand 410, a box holder 420, and a box supply unit 430.

The third pedestal 410 moves up and down, raising the supplied box (B) so that the packaging bag (P) is put into the box (B). Instead of the fourth grip 310 descending and dropping the packaging bag (P) into the box (B), the packaging bag (P) hangs on the fourth grip 310 while the box (B) is placed on the third stand (410). ) and box packaging is performed.

The box holder 420 maintains the top surface of the box B in an open state, and the box holder 420 is arranged to be spaced apart from the third pedestal 410 by the distance at which the top surface of the box is spread.

The box holder 420 moves up and down together with the third pedestal 410. The top surface of the box (B) is unfolded and fixed using the open guide (421) to prevent the top surface of the box (B) from being folded during the rising process.

When the packaging bag (P) is completely inserted into the box (B), the open guide 421 releases the box (B) so that it can be removed. The third stand 410 has a rotating roller rod shape so that the box (B) can be moved to the adjacent conveyor belt (C).

The box supply unit 430 supplies the box B to the third pedestal 410. The box (B) in the unfolded state is sequentially placed on the third pedestal 410 along the supply roller so that continuous packaging work can be performed.

The embodiments of the present invention disclosed in the specification and drawings are merely provided as specific examples to easily explain the technical content of the present invention and to facilitate understanding of the present invention, and are not intended to limit the scope of the present invention. It is obvious to those skilled in the art that in addition to the embodiments disclosed herein, other modifications based on the technical idea of the present invention can be implemented.
