Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to packaging in which various articles are wrapped in wrapping paper or other wrapping material, and then tied tightly with wire or steel bands around the wrapping material. The present invention relates to a packaging and dismantling device for automatically dismantling and removing the packaging materials and automatically taking out the contents.

[Conventional technology]

In general, packages are covered with packaging materials from above and below, and wires or bands are hung over the top and bottom in a vertical or horizontal criss-cross pattern to make them easier to transport and handle. After cutting, the covering material was removed by manually pulling it out with pliers, etc., but this work was inefficient, labor-intensive and dangerous.

For this reason, in the past, processing equipment that can automatically disassemble valves called pulp bales without manual intervention has been disclosed, for example, in Japanese Utility Model Application Publication No. 57-87098 or Japanese Patent Application Publication No. 58-13.
A proposal has been made as shown in Japanese Patent No. 4844.

In this device, a pulp bale is flowed onto a conveyor line, the wire is cut from one end in the middle of the conveyor line, the other side is pulled out, the upper wrapping paper is removed, and the pulp bale is turned over. Remove the lower wrapping paper.

[Problems to be Solved by the Invention] However, in this conventional example, when the wrapping paper of the pulp bale is removed by suction, there is a risk that the contents may be removed all at once, and the suction force is not increased. In many cases, the wrapping paper falls off or a suction error occurs, causing problems in the process, and if the suction power is increased, part of the contents of the valve will also be suctioned and removed, making W1-certified work difficult. In addition to being time-consuming, there are still problems in terms of workability, such as wasting work time because the contents that have gotten into the packaging material cannot be detected, and on top of that, the bale removal unit costs 2 cents and removes at different locations. It is time consuming and has the disadvantage that the overall length of the conveyor becomes long, making it uneconomical.

The present invention aims to accurately eliminate these conventional drawbacks, and allows efficient removal of the wrapping paper that covers the package without any operational errors, and prevents erroneous odor disposal along with the contents. The purpose of this technology is to provide a device that can be unpacked without having to go through the trouble of detection confirmation and post-processing, greatly improves work efficiency, and facilitates safe and efficient packaging and disassembly processing. .

[Means for solving problems]

In the present invention, the wires or bands are cut and removed by cutting the wires or bands in the process of conveying the package, which is wrapped with packaging materials from opposite sides of the contents and bound with wires or bands, by a conveyor. , a device for removing packaging material is equipped with a conveyor for conveying the package from which the wire has been cut and removed to the downstream side, and a part of the pinner for removing the covering packaging material of the package on this conveyor is connected to a vacuum source. The main suction cup and the sub suction cup are provided on a frame that can be raised and lowered, and the main suction cup and the sub suction cup suck the packaging material of the package, and at least the main suction cup This packing and dismantling device is characterized in that the sub suction cup moves before the disk.

〔Example〕

Embodiments of the present invention will be described with reference to FIGS. 1 to 3. A package A is wrapped with wrapping paper from the upper and lower sides of the article, and is made by winding one or more wires B and binding them vertically and horizontally. There is a supply conveyor 1 consisting of a group of rotating rollers that automatically receives and conveys the supplied material, and a rotating conveyor on the downstream side of the conveyor 1 that supports and pushes the package A above the conveyor. A conveyor line is comprised of a turntable 2 and a conveyor 3 that transports the package A received from the turntable 2 to the downstream side, and a stopper 1 for regulating the movement of the package on each conveyor.
), 27, and 77 are provided so as to be freely protrusive and retractable, and the supply conveyor l is provided with a centering mechanism 10 for positioning the package A on the conveyor l, and the turntable 2 is provided with a centering mechanism 10 for positioning the package A on the conveyor l. The wire B wound around the body A is fitted and supported between a large number of protruding rods that protrude at intervals, and the presser feeding mechanism 20 suppresses the curling and bouncing of the wire when being pulled out, and the wire is tied to the package A. A detector 21 detects the wire B that has been cut, a gripper 22 that can hold the detected wire and pull out the cut wire; The conveyor 3 is equipped with a wire cutting and removing mechanism consisting of an automatic nipper 23 that detects and cuts the wire, and further includes a picker section 30 that sucks up and discharges the upper wrapping paper of the package A1 after cutting and removing the wire, and a lower wrapping paper. In order to remove the paper, a reversing unit 3 holds the package A2 directly below the picker unit 30 and moves the lower wrapping paper so that it is on the upper surface.
The packing and dismantling device is equipped with a wrapping paper removing mechanism consisting of 1.

As shown in FIGS. 4 to 6, the centering mechanism 10 has a pair of centering temporary members fixed to arms 14, which are supported by a guide rod 103 via movable pieces 102 so as to be able to slide in opposition to each other.
It is equipped with a pusher drive section 16 consisting of a screw punch 104 into which the movable piece 102 is screwed together and a drive motor that rotates the screw punch.

In addition, a frame 108 having a roller 107 that rotates in the width direction between the centering mechanisms 10 and 10 is disposed between the rotating rollers 13 and 13, and the frame 108 is disposed so as to be movable up and down by the cylinder 15 to constitute the flotation mechanism 12. This is to ensure that the centering mechanism 10 performs the centering work smoothly.

As this centering machine 4'1) 10, the conveyor 1
It consists of a pair of centering plates that move back and forth in the direction perpendicular to the flow direction of the package A flowing upwards.The centering plates press the package A from both sides to center it, and it lifts and lowers when positioning. A movable stopper 1) and a floating mechanism 12 that raises and holds the package A and temporarily stops the transfer on the conveyor 1.
This allows the package A to be raised and lowered to allow smooth movement in the width direction on the conveyor 1.

That is, the conveyor 1 is constructed by arranging a large number of rotationally driven rollers 13 with gaps between them, and the package A to be received is conveyed and moved in a predetermined direction. A centering plate is fixed to an arm 14 that reciprocates in the gap, and a centering mechanism IO is incorporated therein. Cylinder 1) 2 of stopper 1) and air cylinder 15 of lifting mechanism of floating mechanism 12
At the same time, the pusher drive unit 16 is activated, and the packages that have floated up due to the lifting of the floating mechanism 12 are pulled toward the center using a sweeper plate, and even if the packages are of various sizes, the package can be received. Even if the alignment is performed in a distorted state, the alignment is fixed at the center position, and after alignment, the centering plate and the floating mechanism 12
The stopper 1) is restored, retreats from the travel path of the conveyor 1, and disappears, allowing the package A to be transferred to the turntable 2 at a prescribed position.

The stopper 1) is a roller that protrudes between the rollers of a group of rotating rollers forming a conveyor, and is provided on a pivotally supported arm 1) 1, which is moved up and down by a driving cylinder 1. Detector 1) is connected to 2) and detects the flow of the package A.It is controlled by the detection signal of 3. The stoppers 27, 77 provided on the conveyor on the turntable 2 and on the transport conveyor 3 have a similar configuration and are controlled by detection by detectors 1) 4 and 1) 5 that detect the presence or absence of a package.

In this turntable 2, as shown in FIGS. 7 and 8, a table on which a group of rotating rollers 25 arranged as a conveyor for receiving and receiving the package A centered by the supply conveyor 1 is raised and lowered by a lift mechanism 26. The motor 2 is provided with a positioning stopper 27 that is freely provided and can be protruded and retracted, and a fixed table 28 that can be raised and lowered, and a turn drive mechanism 29 that changes the direction of the table by 90 degrees is interposed as necessary.
01, so that it can be lifted to a position where the wires binding the package A are cut and pulled out.

As the positioning mechanism, in addition to the pa 27, the motor 105 for forward and reverse rotation, which reversely rotates part or all of the rotary rollers 25 constituting the conveyor, is connected via a transmission member 106 to return the package A. The motor 105 is controlled in forward and reverse directions by the signal from the detector 1)4.

That is, when the package A arrives at the predetermined position of the stopper 27, the conveyor of the rollers 25 stops, and here again, the conveyor is reversed to perform front-to-back centering in the direction of travel.
(Figure 8!L).

When the centering is completed, the fixing base 28 rises to support the package A so that it does not shift.The next table lift mechanism 26 rises to a predetermined height, and the wire holding machine waits at the upper position! 120 For example, a pressing plate 20 that is suspended by its own weight or spring bias and has a number of protruding rods 20□ projecting in the shape of a crest. The wire B is supported in a state where it is inserted between the protrusions 202 (FIG. 8b).

At this time, lifting and fixing bases 28, which are movable up and down by cylinders 202, are arranged between the rotating rollers 25 and 25, and hold the package A in a floating state, so that when the wire is pulled out, the weight of the contents is reduced to the wire B. It has been taken into consideration that it will not cause any damage.

After that, when the first wire cutting process is completed, the motor 2
At 01, the turntable 2 moves and changes direction by 90 degrees.

In this case, the pressing plate 20 of the presser feed mechanism 20. is spindle 2
0. It turns around and changes direction by 90 degrees.

Next, when the second wire cutting process and the first wire drawing process are completed, the turntable 2 is reversed and returns to the original 0° position. When the second wire pulling process is completed, the table lift mechanism 26 descends, and when it descends to a predetermined position, the fixing table 28 also descends, and the package AI from which the wire B has been removed is transferred to the next conveyor 3 according to the rotation of the conveyor roller 25. The wrapping paper is then sent to the wrapping paper removal R and processed there.

Further, as a cutting mechanism for cutting the wires B bundled in the package A, a cutting unit consisting of an automatic nipper 23 is used as a double unit with two left and right parts as shown in Figures 9 to 1o, and is fixed on the return table 2. The structure is such that the two binding wires of the packed body A can be cut in a short time by each of the left and right units.

When the package A reaches a predetermined position and height, the unit starts moving forward, and when the workpiece position is detected by the detector 24, the slider 50 and the transmission shaft 51 communicate with the motor 52 so that the unit stops moving forward. It has a structure that allows it to move forward and backward.

The slider 50 has a holder 53 connected to a motor 55 through a transmission shaft 54 so as to move in the left-right direction, that is, in the middle direction, and a detector 2 serving as a metal detector is connected to the holder 53.
4. For example, an automatic nipper 23 with a magnetic sensor and a slide unit 56 is provided. In this case, the wire detection sensor detector 24 attached to the slider 5o and the automatic nipper 23 work together to move laterally, and the wire detector 24 searches for the position of the wire B, and detects the wire at that location. The cutter 24 and the wire cutter nippers 23 stop. Once the wire position is found, the slide unit 56 moves forward and stops at a position where the automatic nippers 23 sandwich the wire B, and then the blade section is activated to cut the wire B. At this time, if the automatic nippers 23 do not pinch the wire B and make a cutting error, a mistake detector detects the mistake and informs the annunciator, etc. of the mistake.

The detector detects f! that wire B has definitely been cut.
When the cutting unit recognizes this, the cutting unit retreats and returns to its original position. At this time, the wire detection detector 24 and the automatic nipper 23 that cut the wire B also move in the opposite direction and return to their original positions to stand by in preparation for the next cutting operation.

In order to remove the wire B cut by the automatic nipper 23, the gripper 22 is provided opposite to the automatic nipper 23 and has two grippers 22 on the left and right, which are movable and movable so as to grip the wire B with sufficient force and pull it out. It is attached to two frames 60, and has a structure in which two binding wires can be pulled out at the same time.

1) As shown in the figure, a wire detection sensor 21 and an automatic wire gripper 22 are attached to the frame 60, and when the package position is detected, the wire detector 21 and gripper 22 move horizontally. The frame 60 starts moving and searches for the position of the tied wire B.
A holder 61 that moves in the left-right direction, that is, in the width direction, is connected to a motor 63 through a transmission shaft 62.
A metal detector 21, for example a magnetic sensor, and an automatic gripper 22 with a slide unit 64 are provided. The frame 60 is mounted on a rail 66 with tires 65 so as to be able to move back and forth, and a chain 70 or a rope is hung around a driving wheel 68 and a rolling wheel 69 operated by a forward and reverse rotating motor 67. Transmission is carried out through cables such as cables, and forward and backward movements are repeated.

When the wire position is detected by the detector 21, the horizontal movement of the slide holder 61 is stopped and the wire gripper 22
The slide unit 64 to which the wire gripper 22 is attached moves forward, and the wire gripper 22 is in a position to sandwich the binding wire. After confirming that the slide unit 64 has moved completely forward, compressed air is supplied to the drive cylinder 221 of the wire gripper 22. and grab the binding wire.

To confirm that the binding wire has been grasped, a detector (not shown) detects this, and then activates the wire pulling drive motor 67 to move the frame 60 and pull out the binding wire.

A pair of squeezing rolls 57 are attached to this wire drawing unit in order to correct the bending of the binding wire and straighten it when pulling out the binding wire B.

This consists of two rolls 57°57 as shown in Figures 1) to 12.
With the air cylinder 58, one is movable and the other is fixed, or both are movable, and the wire gripper 22 grasps the wire B and starts to retreat, and when it retreats to a certain fixed position, it operates and squeezes the wire B.

This squeezing roll 57 is preferably provided with a plurality of partition rings or grooves to facilitate straightening the wire, and two or more squeezing rolls 57 may be arranged in multiple groups or in multiple rows. Alternatively, the rolls can be arranged in a manner that increases the effect of squeezing the wire, such as by shifting or staggering the rolls and arranging them in a ramp. When the pulling unit retreats to the final position, the binding wire B that has been pulled out is transferred to the drive cylinder 22 of the wire gripper 22,
The compressed air supplied to the wire gripper 2 is exhausted and
2 is opened and the binding wire falls.

This fallen binding wire is discharged out of the system by a wire discharge device 73 operated by a motor 59.

On the other hand, package A from which wire B has been removed is turntable 2.
is lowered and the conveyor roller 25 is driven to send it out onto the next conveyor 3, and when the stopper foot 0 controlled by the detector 1) 5 stops at a predetermined position, the picker for removing the wrapping paper of the package A+ section 30 is activated.

As shown in FIGS. 13 to 15, this pincer part 30 is attached to a main suction cup 35 of a suction pad connected to a vacuum pump 34 on a frame 33 that is vertically and vertically suspended from a cable 32 such as a chino or a screw shaft. The rope 32 is wound up and lowered by a lifting motor 38 via a transmission mechanism 37, and the suction unit is raised and lowered to attach the suction unit to the wrapping paper. Suction 1) The suction cups 35 and 36 are stopped at a position where they can come into contact with each other.The suction cups 35 and 36 are connected to the vacuum pump 34 with a flexible vibrator 39 to generate suction force, and the suction cups 35 and 36 are connected to the vacuum pump 34 with a flexible vibrator 39 to generate suction force, and the suction cups 35 and 36 are Each support rod can be raised and lowered 35. ．． 36. is cylinder 40 or spring machine 1) 1
41 so as to move up and down. In this case, the main suction cups 35 are arranged in the center of the sub suction cups 36 in preparation for a plurality of peripheries, and after the frame 33 approaches the package A1, the sub suction cups 36 move up and down first to remove the package A, After the wrapping paper C is slightly lifted from the contents, the main suction cup 35 is set so as to suck it with a two-stage Morsilon, which is designed to prevent the contents from being sucked together with the wrapping paper to be removed. ing. In addition, the sub suction cups 36 are prepared so that the plurality of sub suction cups 36 are arranged in a horizontal direction instead of moving in the vertical direction, and after sucking and expanding the wrapping paper around the package A1, the main suction cups 36 35 may be used to suck it up, or it may be vertical,
It is also possible to use a combination of horizontal and horizontal types.

That is, in the package suction removal device, when the binding wire B is removed and sent to a predetermined position by the conveyor, the suction unit suspended from the upper part is activated by the lifting motor 3.
Start descending at 8.

The suction unit descends again and picks up the upper wrapping paper C of the package A1.
Main and sub suction cups 35 and 36 are arranged to suction the top surface of the package under negative pressure to remove the wrapping paper C by suction, and the sub suction cups 36 stop at that position.
is attached and moves up and down to deflect the wrapping paper so that it can be easily removed.

In order to prevent the contents D of the package A, for example, the pulp from being taken out, when removing the wrapping paper C, a sub-suction cup 36 of a suction pad is attached to each side of the valve. This is a suction pad that detects the side position of the pulp and starts suctioning it to accommodate the size. When the wrapping paper C is adsorbed in this manner, the suction unit elevating motor 38 is reversed, thereby lifting the wrapping paper C upward. After suction and lifting, the unit moves laterally by starting the motor 45 of the cart 43 running on the rail 44, and when it reaches the upper part of the wrapping paper receiving box, the vacuum is turned off and the upper wrapping paper C is dropped into the receiving box. . In this case, if the wrapping paper C is picked up incorrectly, a detector installed in the frame 33, i.e., a sensor such as a phototube, should be detected and a lamp or alarm should be displayed, or the pink-up operation should be performed again, or the machine should be stopped. It is better to

In addition, it is considered that the suction action of the sub-suction cup 36 and the main suction cup 35 is carried out simultaneously or with a time lag to separate the wrapping paper from the contents and lift it up before deodorizing. This can be easily handled by moving the sub-suction cup first.

When this operation is completed, the device returns to the initial suction position and waits to suction and remove the next wrapping paper.

Furthermore, since there is an upper wrapping paper C in the contents of the package from which the upper wrapping paper C has been removed, as a mechanism for removing the upper wrapping paper C, a reversing section 31 is connected to the rotating body 71 as shown in FIGS. 16 to 18. A pair of separating forks 72.degree. 72 are provided, each supported by a screw shaft 73, so that the lower wrapping paper can be held and lifted on the conveyor 3 together with the lower wrapping paper.

This screw shaft 73 may be a right-handed screw or a left-handed screw with an upper and lower axle, or may be divided into multiple shafts. , move the forks 72, 72 up and down by moving each fork 72, 72 closer to each other or farther apart, sandwiching the article between them, and rotate the rotary plate 71 by the motor 76 via the transmission member 79 to rotate it 180 degrees. Then, after the lower wrapping paper is on the upper side, the fork 72 is expanded and the package is transferred to the transport conveyor 3, placed on it, and moved backward, and then the lower wrapping paper C is similarly suctioned and removed using the pinker part 30. Then, the contents of the package are transferred to the next process by the conveyor 3 by the operation of the motor 85.

That is, the forks 72 and 72 which grasp the plate-like pulp which is the contents including the lower wrapping paper are moved toward or apart from each other by the motor 75 via the screw shaft 73 to grasp the pulp, or the forks 72 are moved to grasp the pulp. A detection switch 78 is installed to confirm and detect that the device has been grabbed, and this detection switch 78
When the fork motor 75 is activated, the fork motor 75 is stopped and locked.

When the fork stops and locks, a reversing motor 76 that reverses the pulp rotates, causing the fork to rotate. When the fork motor 75 rotates 180 degrees, the fork motor 75 rotates in the opposite direction and lowers the grabbed pulp onto the conveyor.

Note that this reversing device is equipped with a motor 45 for self-propelled movement on rails, and moves forward to the position of the pulp on the conveyor when grasping and reversing the pulp. Also, when the pulp is reversed and placed on the conveyor, as soon as it is retracted, the forks are reversed and returned to the initial angle to prepare for the next operation.

In this case, the suction unit is attached to the fork 7 of the reversing section 31.
It is possible to perform simultaneous processing in conjunction with the opening/closing operations of 2, and it is considered to incorporate a mechanism that rotates the rotary plate 71 supporting the fork 72 to discharge the wrapping paper.

For example, a package A is supplied, which includes a wrapping paper for packing plate-shaped valves used as a raw material for paper manufacturing, and a punting wire B that binds two pieces of pulp from above the wrapping paper in a vertical and horizontal pattern. A cutting unit that simultaneously searches the 82 bundled wires on the package A and cuts the wires B in the process of sequentially transferring them to the turntable 2 and the transport conveyor 3 by feeding them into the conveyor L, and the cut wire The wire B is cut and pulled out using a gripper unit for pulling out the turntable 2.
After changing the direction and cutting and pulling out the wire on the other side, the picker section 30, which has a plurality of vacuum pads, removes the wrapping paper C that wraps the pulp by performing a suction action in a two-stage motion and removing the upper wrapping paper. After the paper is removed by suction, it is reversed by the reversing section 31 and the lower wrapping paper is placed on the upper side, and then the picker section 30
In the same way, suction removal can be performed sequentially to efficiently unpack the package automatically without manual intervention.

In the figure, 4.5 is a frame, 17 is a conveyor motor, 18 is a chino or belt, 46 is a transmission member, 47 is a guide rod, 48
are wheels, 49 is a rail, 80 is a motor for traveling the picker section, 81 is a transmission member that uses a screw shaft or the like to reciprocate the group of sub suction cups 36, 82 is a linear shaft, 83 is a slider, 84
The motor is used to reciprocate the reversing machine.

In the specific example shown in FIGS. 19 to 23, the picker unit 30 reciprocates its sub-suction cup 36 in the horizontal direction to suck and spread the wrapping paper C around the package A1, and then sucks it with the main suction cup 35. It has a vertical and horizontal combination type that can be pulled up and removed.
