Description

The present invention relates to a packaging device that packs, for example, a plurality of elongated bags packed with a plurality of noodles rolled into one serving in a line into a storage box.

BACKGROUND ART Traditionally, noodles such as Chinese noodles and soba noodles produced in noodle factories are packaged in bags made of resin film or the like, then packed in storage boxes and shipped. Since the work of packing each bag into a storage box is complicated, in recent years it has been common to use a boxing device to pack each bag into a storage box.

For example, the packaging device disclosed in Patent Document 1 includes a conveyor that conveys each bag and sequentially drops it from the downstream end in the conveying direction, and below the downstream end of the conveyor in the conveying direction, A pair of door members are arranged in parallel in the horizontal direction orthogonal to the door member. The conveyor is configured to be expandable and contractible in the conveyance direction, and drops each bag while shrinking from a predetermined reference state to the opposite side of the conveyance direction so that each bag is aligned in the conveyance direction on both door members. At the same time, when the bag is dropped a predetermined number of times, it will extend in the transport direction until it reaches the reference state. Both door members are able to rotate downward while separating from each other, and by rotating downward in a state where X bags are arranged on both door members to form a bag group, the bag group is formed. is dropped and packed into storage boxes installed below both door members.

By the way, if you try to use a boxing device like Patent Document 1 to box a flexible elongated bag in which a plurality of noodles rolled into one meal are arranged in a row, The shape of a long bag easily changes, so if the condition when it is dropped from the conveyor changes even slightly from the standard condition, its shape will change between the time it falls from the conveyor and reaches the top of both door members. This results in a large change, and the bags are arranged in a disordered manner on both door members. Particularly in recent years, there has been a demand for efficient packaging work, but the more efficient the packaging work is by increasing the transport speed and expansion/contraction speed of the conveyor, the more each bag is placed on both door members. will no longer line up neatly. Therefore, it is necessary to add a structure that prevents the states of the bags from varying during transportation, which may make the device expensive.

The present invention has been made in view of the above, and its purpose is to efficiently pack a plurality of flexible long bags in neatly aligned boxes at a low cost. Our goal is to provide packaging equipment that is ideal for packaging products.

In order to achieve the above object, the present invention is characterized by having a structure in which each bag is transferred to an area above the storage box and aligned in that area.

Specifically, the following solution was taken for a box packing device that is configured to drop a plurality of long bags into a storage box that opens upward and pack them into boxes.

That is, in the first invention, a group of bags is created by arranging a plurality of elongated bags packed with a plurality of single-serving portions lined up in a row in a direction perpendicular to the longitudinal direction of the bags, and then dropping the group of bags. The packaging device is configured to pack the bags into storage boxes that open upwardly, and sequentially conveys the bags to a first area set on an endless belt with the longitudinal direction of the bags aligned with the conveyance direction. a support plate arranged in parallel to the side of the conveyor and capable of supporting the bag group in a second region; and a positioning plate extending parallel to the conveying direction of the conveyor, and aligning the bags into the bag group by transferring the bags that reach the first area to the second area each time. and a dropping means for moving the support plate away from the second area and dropping the bag group in the second area into the storage box installed below the second area. The bag transfer means includes a moving unit disposed above the first and second areas and having a horizontal moving part movable in a horizontal direction perpendicular to the conveyance direction of the conveyor; an elevating unit that is attached to the moving part and has an elevating part that can be raised and lowered; and an elevating unit that is attached to the elevating part, has an original position in the first area, and has a shape that extends in parallel with the conveyance direction of the conveyor. and a control means for controlling the moving unit and the elevating unit, and the control means is configured to move the pressing frame to the first region when the first bag reaches the first region. While pressing against the second bag, the first bag is moved toward the second region side until the first bag extends in the longitudinal direction and is sandwiched between the pressing frame and the positioning plate on both sides. After controlling the moving unit to perform a first operation of pressing the second bag with the pressing frame and transferring it to the second area, the lifting unit raises the pressing frame and the moving unit The moving unit and the lifting unit are moved so that a second operation is performed in which the pressing frame is moved toward the first area, and then the lifting unit lowers the pressing frame to return the pressing frame to the original position. When the second bag reaches the first area, the pressing frame is moved toward the second area while pressing against the second bag, and the second bag is moved to the second area. The moving unit is controlled to transfer the bodies to adjacent positions on the first region side when viewed from the first bag, and the bags are sequentially transferred and aligned.

In a second invention, in the first invention, the bag transfer means is provided in two pieces at a predetermined interval in the transport direction of the conveyor, and the control means is configured to control one of the two bag body transfer means. When controlling the moving unit of one of the bag transfer means so that the bag transfer means performs the first operation, the other of the two bag transfer means performs the second operation. A moving unit and a lifting unit of the other bag transfer means are controlled.

In a third invention, in the second invention, each lifting unit provided in each of the two bag body transfer means is a fluid pressure cylinder, and the fluid pressure cylinder has a piston rod that expands and contracts downward. The dimension D1 between the two piston rods in the transport direction of the conveyor is set shorter than the longitudinal dimension D2 of the bag body, and the longitudinal dimension D3 of the press frame is set to be shorter than the longitudinal dimension D2 of the bag body. It is characterized by being set shorter than the dimension D1.

In a fourth invention, in the third invention, the pressing frame includes a first plate-shaped frame portion extending from the piston rod in parallel with the conveying direction of the conveyor, and having a plate surface facing in the vertical direction; A second plate-shaped frame part is provided continuously on one side edge of the first plate-shaped frame part, and has a plate surface facing in a horizontal direction perpendicular to the conveyance direction of the conveyor, and has an L-shaped cross section. The first plate-shaped frame portion is characterized in that it has a triangular shape in plan view such that the other side edge gradually approaches the one side edge as it goes to the tip.

In the first invention, each bag that is sequentially transferred from the first area on the conveyor to the second area on the support plate by the pressing frame is placed in parallel in the horizontal direction perpendicular to the longitudinal direction of the bag. Due to the pressing operation, force is applied between the pressing frame and the positioning plate in a direction in which they approach each other. Therefore, each bag deforms without creating any gaps between adjacent bags, and falls into the storage box as a group of bags neatly aligned in the horizontal direction perpendicular to the longitudinal direction. The bags can be packed in boxes efficiently using the transfer operation of each bag by the pressing frame. Moreover, after the pressing frame transfers each bag from the first area to the second area, it returns to its original position while avoiding the conveyance path of the conveyor upward. Therefore, there is no need to stop conveyance of each bag by the conveyor due to the movement of the pressing frame, and in this respect as well, the boxing operation can be carried out efficiently. Furthermore, since the structure is not such that the bags are aligned while being dropped as in Patent Document 1, a guide structure is added to correct the posture of each bag when it is transferred to the second area. There is no need for this, and the equipment can be made inexpensive.

In the second invention, when one pressing frame transfers the bags from the first area to the second area and creates a bag group in the second area, the other pressing frame transfers the bags from the first area to the second area. Since the next bag to be transferred to the second area is ready to be pressed, the interval between each bag to be transferred is shortened, and each bag can be boxed more efficiently.

In the third invention, since the dimension from the tip of the piston rod to the tip of the press frame is shortened, the bending moment applied to the piston rod is reduced, making it possible to provide equipment that is less likely to break down.

In the fourth invention, since the pressing frame has an L-shaped cross section, it has high rigidity. Therefore, even if the bag body is repeatedly pressed, failure of the pressing frame due to damage or deformation can be prevented. In addition, since the first plate-shaped frame part has a triangular shape with a tapered tip, for example, the bending applied to the piston rod is more difficult than in the case where the first plate-shaped frame part has a strip-like shape in plan view. The moment can be reduced, and the device can be made less likely to break down.

The same reference numerals will be given, and detailed explanation will be omitted.

When the rotating shaft 37a of each second drive motor 37 is rotated to one side, the lever plate 39 swings via the crank disk 37b, crank pin 37c, and connecting rod 38. As shown in FIGS. 4 and 5, each support plate 35 rotates downward while separating from each other in a double-folded manner, and then returns to its original position extending in the horizontal direction.

As shown in FIGS. 1 to 3, the bag transfer units 4 are provided in pairs above the first region R1 and the second region R2, symmetrically in the transport direction of the conveyor 2 and spaced apart from each other by a predetermined distance. It is suspended from a band-shaped suspension frame 30 extending in a horizontal direction orthogonal to the conveyance direction of the conveyor 2. Hereinafter, one bag transfer unit 4 will be referred to as a bag transfer unit 4A, and the other bag transfer unit 4 will be referred to as a bag transfer unit 4B.

As shown in FIG. 3, the bag transfer unit 4A includes an electric slider 41 (moving unit) fixed to the upper surface of the hanging frame 30 and extending along the longitudinal direction of the hanging frame 30. The electric slider 41 includes a rectangular bar-shaped slide rail 41a and a slider 41b (horizontal moving section) that is attached to the top of the slide rail 41a and is movable along the slide rail 41a.

A hydraulic cylinder 42 (elevating unit) is attached to a portion of the slider 41b that protrudes outward from the slide rail 41a so as to extend downward, and the hydraulic cylinder 42 has a piston rod 42a that extends and contracts downward. There is.

A mounting bracket 42b (elevating section) is attached to the tip of the piston rod 42a, and the mounting bracket 42b moves up and down as the piston rod 42a expands and contracts.

As shown in FIGS. 1 to 3, the pressing frame 43 includes a first plate-shaped frame part 43a that extends from the tip of the piston rod 42a along the conveyance direction of the conveyor 2, and has a plate surface facing in the vertical direction. , a second plate-shaped frame part 43b that is provided continuously on one side edge of the first plate-shaped frame part 43a, and whose plate surface faces in the horizontal direction perpendicular to the conveying direction of the conveyor 2; The shaped frame portion 43a has a triangular shape in a plan view such that the edge on the other side gradually approaches the edge on one side as it approaches the tip.

The bag transfer unit 4B is the same as the bag transfer unit 4B except that it is arranged symmetrically in the conveying direction of the conveyor 2 when viewed in the direction of the rotation axis of the rotation shaft 34 with respect to the bag transfer unit 4A. Since it has the same configuration as 4A, the same configuration is given the same reference numeral and detailed explanation will be omitted.

As shown in FIG. While it is set shorter than the dimension D2, it has a dimension corresponding to the longitudinal dimension D3 of the press frame 43. Note that the lengthwise dimension of the pressing frame 43 is set to a size that can press the center of gravity of the bag body 10 located in the first region.

Further, the original position P1 of each pressing frame 43 in the bag transfer units 4A and 4B is set to the first region R1.

On the opening/closing operation unit 36 side of the second region R2, as shown in FIG. 2, a positioning plate 44 having an L-shaped cross section and extending along the conveyance direction of the conveyor 2 is fixed to the pedestal 32.

Then, as shown in FIGS. 6 to 11, the bag transfer units 4A and 4B are transported by the conveyor 2 by sliding the slider 41b to one side from the state where the pressing frame 43 is located at the original position P1. The bags 10 that arrive at the first area R1 are alternately transferred to the second area R2, and each bag 10 that is sequentially transferred to the second area R2 is moved by the positioning plate 44 and the pressing frame. 43, so that the bag group 12 is neatly aligned.

Moreover, both opening/closing operation units 36 rotate both support plates 35 downward by the rotational operation of both second drive motors 37 and move them to a position that does not correspond to the second region R2. The structure is such that the body group 12 is dropped into the storage box 11 and packed into the box.

The first drive motor 2a, the second drive motor 37, the electric slider 41, and the hydraulic cylinder 42 are connected to a control panel 5 (control panel 5) that controls the first drive motor 2a, the second drive motor 37, the electric slider 41, and the hydraulic cylinder 42. means) are connected.

As shown in FIG. 1, the control panel 5 outputs an operating signal to the first drive motor 2a to move the endless belt 2d around at a constant speed to move each bag 10 to the first region R1. It has become.

Further, as shown in FIGS. 6 to 11, the control panel 5 outputs an activation signal to the electric slider 41 when the bag 10 reaches the first region R1 with the pressing frame 43 located at the original position P1. Then, by moving the slider 41b toward the second region R2, the bag 10 is pressed by the pressing frame 43 until the bag 10 is sandwiched between the positioning plate 44 and transferred to the second region R2. The bag transfer unit 4 is made to perform one operation M1.

Furthermore, after the bag transfer unit 4 performs the first operation M1, the control panel 5 outputs an operation signal to the electric slider 41 and the hydraulic cylinder 42 to raise the press frame 43 and move the slider 41b to the first operation M1. The bag transfer unit 4 is caused to perform a second operation M2 in which the bag is moved to the region R1 side, and then the pressing frame 43 is lowered and returned to the original position P1.

When the control panel 5 controls the electric slider 41 and hydraulic cylinder 42 of one bag transfer unit 4 so that the other bag transfer unit 4 performs the first operation M1, the control panel 5 The electric slider 41 and hydraulic cylinder 42 of the other bag transfer unit 4 are controlled so that the unit 4 performs the second operation M2.

Next, the packaging operation of each bag 10 by the packaging device 1 will be described in detail.

First, the endless belt 2d of the conveyor 2 is rotated at a constant speed to convey the bag 10 toward the first region R1 with its longitudinal direction matching the conveying direction, and in the first region R1, the stop plate 2e to stop it by touching it.

Then, the bag transfer unit 4A starts the first operation M1. That is, as shown in FIG. 6, the slider 41b of the bag transfer unit 4A with the press frame 43 located at the original position P1 is moved toward the second region R2. At this time, the second plate-shaped frame portion 43b of the pressing frame 43 presses the bag 10 located in the first region R1 in a horizontal direction perpendicular to its longitudinal direction and starts to move it toward the second region R2.

The bag 10 pressed by the pressing frame 43 of the bag transfer unit 4A is transferred to the second region R2 and comes into contact with the positioning plate 44, as shown in FIG.

On the other hand, the bag transfer unit 4B starts the second operation M2 while the bag transfer unit 4A is performing the first operation M1. That is, the piston rod 42a of the hydraulic cylinder 42 in the bag transfer unit 4B in which the pressing frame 43 approaches the positioning plate 44 is contracted to raise the pressing frame 43, and the slider 41b is moved to the first region R1 side. let When the press frame 43 reaches above the first region R1, the press frame 43 is lowered and returned to the original position P1, as shown in FIGS. 8 and 9. At this time, the press frame 43 of the bag transfer unit 4B moves above the press frame 43 of the bag transfer unit 4A, so it does not contact the press frame 43 of the bag transfer unit 4A.

Next, the bag transfer unit 4B starts the first operation M1. That is, by moving the slider 41b of the bag transfer unit 4B toward the second region R2, it then comes into contact with the stop plate 2e and presses the bag 10 located in the first region R1, thereby moving it to the second region R2. Start moving towards. Then, the bag 10 pressed by the pressing frame 43 of the bag transfer unit 4B is transferred to the second region R2 and is already in contact with the positioning plate 44, as shown in FIG. Contact 10.

On the other hand, the bag transfer unit 4A starts the second operation M2 while the bag transfer unit 4B is performing the first operation M1. That is, the piston rod 42a of the hydraulic cylinder 42 in the bag transfer unit 4A in which the pressing frame 43 approaches the positioning plate 44 is contracted to raise the pressing frame 43, and the slider 41b is moved toward the first region R1 side. let When the press frame 43 reaches above the first region R1, the press frame 43 is lowered and returned to the original position P1.

Thereafter, the bag transfer unit 4A and the bag transfer unit 4B alternately perform the first operation M1 and the second operation M2, so that the positioning plate 44 and A plurality of bags 10 are sandwiched between the press frame 43 and the bag group 12 in an aligned state.

After that, the rotation shaft 37a of each second drive motor 37 is rotated. Then, as shown in FIGS. 4 and 5, both support plates 35 rotate downward while separating from each other in a double-fold manner via the crank disc 37b, crank pin 37c, connecting rod 38, and lever plate 39, and the bag body is opened. The group 12 falls inside the storage box 11.

Thereafter, after repeating the above-mentioned operation and dropping the bag group 12 into the storage box 11 multiple times, the storage box 11 is transported to the next process by a transporter (not shown), and the empty storage box 11 is placed on both sides. It is conveyed to a position below the opening/closing operation unit 36.

As described above, according to the embodiment of the present invention, each bag 10 that is sequentially transferred from the first region R1 on the conveyor 2 to the second region R2 on the support plate 35 by the pressing frame 43 is In the state where they are arranged in parallel in orthogonal horizontal directions, a force is applied between the press frame 43 and the positioning plate 44 in a direction in which they approach each other due to the press operation by the press frame 43. Therefore, each bag 10 is deformed without creating a gap between each adjacent bag 10, and becomes a bag group 12 that is neatly aligned in the horizontal direction perpendicular to the longitudinal direction of the bags 10. The bag bodies 10 are then dropped and stored, and by using the transfer operation of each bag body 10 by the pressing frame 43, it is possible to efficiently pack the bags into boxes.

Moreover, after the pressing frame 43 transfers each bag 10 from the first region R1 to the second region R2, it returns to the original position P1 while avoiding the conveyance path of the conveyor 2 upward. Therefore, there is no need to stop the conveyance of each bag 10 by the conveyor 2 due to the movement of the press frame 43, and in this respect as well, the boxing operation can be carried out efficiently.

Furthermore, since the structure is not such that the bags 10 are aligned while being dropped as in Patent Document 1, a guide structure that corrects the posture of each bag 10 when transferring the bags 10 to the second region R2 is required. There is no need to add anything, and the equipment can be inexpensive.

Further, when one pressing frame 43 transfers the bag 10 from the first region R1 to the second region R2 and creates the bag group 12 in the second region R2, the other pressing frame 43 Since the next bag 10 to be transferred from the first area R1 to the second area R2 is ready to be pressed, the interval between transferring each bag 10 is shortened, and each bag 10 can be boxed more efficiently. I can do it.

Further, the dimension D1 between the two piston rods 42a in the conveyance direction of the conveyor 2 is set shorter than the longitudinal dimension D2 of the bag 10, and the longitudinal dimension D3 of the press frame 43 is set to be shorter than the longitudinal dimension D2 of the bag body 10. Therefore, the dimension from the tip of the piston rod 42a to the tip of the press frame 43 becomes shorter. Therefore, the bending moment applied to the piston rod 42a is reduced, making it possible to provide equipment that is less likely to break down.

Furthermore, since the press frame 43 has an L-shaped cross section, it has high rigidity. Therefore, even if the pressing operation of the bag body 10 is repeated repeatedly, failure of the pressing frame 43 due to damage or deformation can be prevented. Furthermore, since the first plate-like frame portion 43a has a triangular shape with a tapered tip, the piston rod 42a The bending moment applied to the device can be reduced, and the device can be made less prone to failure.

In the embodiment of the present invention, a plurality of noodles 10a are housed in the bag body 10, but even if the bag body 10 is flexible and stores powder, etc., the packaging device 1 of the present invention can box it. Can perform packing work.

Further, in the embodiment of the present invention, the hydraulic cylinder 42 which is a fluid pressure cylinder is used as the lifting unit for raising and lowering the pressing frame 43, but an air cylinder or an electric slider may be used, or other mechanism may be used for pressing the pressing frame 43. The frame 43 may be moved up and down.

Further, in the embodiment of the present invention, the hydraulic cylinder 42 is moved horizontally by the electric slider 41, but the hydraulic cylinder 42 may be moved horizontally by another mechanism.

Further, in the embodiment of the present invention, two bag body transfer units 4 are prepared and the bags 10 are transferred alternately, but one bag body transfer unit 4 is used to transfer the bags 10. The configuration may be such that the

The present invention is suitable, for example, for a boxing device that packs a plurality of elongated bags packed with a plurality of noodles rolled into one meal in a lined state into a storage box.
