Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bag opening device, and in particular, after the surface of a powder bag filled and sealed with powder or fine particles used in the fields of food, pharmaceuticals, chemicals, etc., is opened (on the material discharge surface). The present invention relates to a bag-opening device that can continuously perform formation), discharge of raw materials, disposal of empty bags, and the like in a series of operations.
[0002]
[Prior art]
Powders, fine particles, etc. (hereinafter simply referred to as raw materials) used in a wide range of industrial fields such as foods, pharmaceuticals, and chemicals are filled and sealed in bags made of paper, cloth or other materials at milling manufacturers. Shipped in. In each industry using raw materials, a single raw material or a plurality of mixed raw materials are processed into various products according to the purpose of use. For commercialization, it is necessary to take out the raw material from the bag. To that end, it is necessary to form an opening surface for taking out the raw material in the bag.
[0003]
The simplest means for forming the opening surface is to sew both ends of the bag and unscrew the sewing thread that closes the bag mouth, or widen the bag mouth, or use a cutter knife to open the appropriate part of the bag surface. It was cut open to form an opening surface. Further, the bag is cut with a disk-shaped saw blade that rotates at high speed, or the bag is cut into two pieces with cutting blades provided above and below the bag.
[0004]
[Problems to be solved by the invention]
The bag is filled with pure raw materials without contamination and without contamination, but is stored on the bag. When the bag is opened by the means and methods described above, it adheres to the bag surface. There is a risk that dust, dust, or the like that has entered the bag through the opening surface, or dust, dust, or the like may be mixed into the extracted raw material.
[0005]
In particular, the bag is made up of multiple layers of paper, cloth, etc., so when using a cutter knife to open the bag surface, it cannot be opened at once, and the cutter operation is repeated. As a result, bag chips and fibers were generated, which entered the bag and mixed with the raw materials. In this way, mixing of garbage, chips and the like in the raw material contaminates the raw material and cannot be used for product processing, product manufacturing, or the like.
[0006]
Furthermore, after unraveling the sewing thread and opening the bag using a cutter knife, the operator holds the bag with both hands to remove the raw material from the opening surface, and the raw material is discharged with the opening surface facing downward. The labor burden on the staff was large and the work efficiency was poor.
[0007]
In consideration of the above, in recent years, the opening surface of the bag and the removal of the raw material from the opening surface have been mechanically performed. However, each operation is performed independently at different locations. It was broken. For this reason, an operator has to carry the opened bag to the raw material discharge section, but the raw material spilled from the bag during transportation, and a large amount of useless raw material that cannot be used was generated. In addition, even when the opening surface is formed or the raw material is discharged in a close place, the bag must be moved manually, and the opening and discharging operations cannot be performed automatically by a series of operations, and the entire The processing efficiency was poor.
[0008]
Accordingly, the applicant of the present application disclosed in Japanese Patent Laid-Open No. 6-144430, a powder bag transfer device, a powder bag supply device, a bag opening device having an opening for taking out contents in the powder bag, and a powder from the opened powder bag. A powder bag automatic processing device is provided that integrates a discharge device for taking out the body, a take-out device for discarding the empty bag, and the like as an integrated device, and performing a series of operations from opening the bag to discarding the empty bag.
[0009]
However, since this apparatus does not have a mechanism for cleaning the surface of the powder bag, when the powder line 1 accommodated in the box 21 is formed into a square shape by the cutter 31, dust and dirt are removed from the cutter surface. Etc. may enter the powder bag 1.
[0010]
Further, when the powder is bulging partly in the powder bag 1, when the powder bag 1 is put into the box 13 of the supply device 4 from the transfer device 3, the raised portion is the edge of the box 13. It may not be possible to enter. Further, when the cutter drive mechanism 23 moves the cutter 31 in the X-axis or Y-axis direction, since the ball screw mechanism is used, the metal powder generated by the friction between the metals adheres to the upper surface of the powder bag 1, and this It was a cause of contamination of the powder.
[0011]
In view of the various problems of the prior art described above, the present invention cleans the surface of the powder bag and arranges the powder bag in a flat shape to make the raw material distribution uniform. It is an object of the present invention to provide a bag opening device capable of automatically and continuously performing an operation of intermittently sending to a discharge unit and discarding empty bags.
[0012]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows the entire bag opening device of the present invention. This bag opening device is filled with a raw material such as powder and fine particles and sealed, and an aligned portion 2 of a powder bag 1 and a bag size adjustment of the powder bag 1. Part 3, transfer device 4 for powder bag 1, bag opening part 5 for powder bag 1 and material discharge part 6. Alignment part 2, bag shaping part 3, bag opening part 5 and discharge part 6 are powders. It is installed close to the same plane along the transfer direction of the bag 1. The transfer device 4 is located above the bag opening portion 5 and the discharge portion 6.
[0014]
As shown at the right end of FIG. 1, the powder bag 1 is vertically and horizontally aligned on the pallet 7 and stacked in a plurality of upper and lower stages and placed near the alignment portion 2. The powder bags 1 on the pallet 7 are placed on the alignment unit 2 one by one by the depallet robot 8. The alignment unit 2 includes a belt conveyor 9 that is circulated and driven by a motor M, and transfers the powder bag 1 to the bag shaping unit 3. When the powder bag 1 is placed on the alignment unit 2, the alignment unit 2 moves in the transfer direction. The orientation is determined.
[0015]
That is, the powder bag 1 is a flat rectangular body, and in the present invention, the powder bag 1 is placed on the alignment portion 2 so that the long side faces the transfer direction. When the powder bag 1 placed on the alignment unit 2 by the depallet robot 8 is in an oblique state with respect to the transfer direction, the orientation is adjusted by the alignment plates provided on the plurality of cylinders 10. .
[0016]
The bag regulating unit 3 is an independent sealed space due to the housing structure, and has a cleaning mechanism capable of air shower by the injection pipe 11 and a planar pressure compaction mechanism by the compaction roller 12 inside. The entrance and exit on both sides of the bag 1 in the transfer direction can be opened and closed by a shutter 13.
[0017]
The powder bag 1 in which the direction of the transfer direction is adjusted is sent to the bag shaping unit 3 by the belt conveyor 9, but at least the shutter 13 on the entrance side facing the alignment unit 2 is opened, so the powder bag 1 is adjusted. The roller conveyor 14 that is fed into the bag portion 3 and is rotationally driven by the motor M can be moved forward.
[0018]
The shutter 13 on the entrance side is closed at the position where the powder bag 1 enters the bag adjusting unit 3, and the inside is sealed. The powder bag 1 is moved forward by the roller conveyor 14, but as shown in FIG. 2, air injection pipes 11 are installed on the upper and lower sides of the powder bag 1, so that the powder bag 1 passes through the injection pipe 11 from the external air pressure feeding device. If air is sprayed toward the air bag, the air shower blows off dust, dust, etc. adhering to the surface of the powder bag 1, and the floating dust is forcibly applied to the dust collector installed outside from the bottom of the bag regulating unit 3. Sucked.
[0019]
Meanwhile, the both-side entrances and exits of the bag-sizing unit 3 are closed by the shutter 13, so that dust is not released to the outside. Note that the injection pipe 11 may not only inject air in the vertical direction, but may also be rotated left and right to change the air injection direction.
[0020]
The powder bag 1 cleaned by the air shower is subjected to plane rolling by the aforementioned rolling mechanism. As described above, when the upper surface of the powder bag 1 is gripped by the depallet robot 8, the central portion of the powder bag 1 may protrude upward in a mountain shape. Moreover, in the powder bag 1, a raw material may be shifted to one side, and as shown in FIG.
[0021]
The rolling mechanism smoothes the bulges and bulges 15 in a flat shape so that the raw material is uniformly distributed inside the powder bag 1 and the surface shape of the powder bag 1 is adjusted. For this reason, the two support arms 16 are configured so that both ends of one rolling roller 12 having a length equal to or longer than the length of the long side of the powder bag 1 can rotate along the traveling direction of the powder bag 1. It is hung.
[0022]
Since the upper ends of the two arms 16 are rotatably connected to the housing constituting the bag-sizing portion 3, the pressure roller 12 can also be rotated according to the arm 16, and the base portion can be rotated to the housing. By connecting the rod end of the air cylinder 17 that is axially connected to the support arm 16 so as to be rotatable, the rotation angle of the pressure roller 12 is regulated.
[0023]
When the powder bag 1 having a finely finished surface is moved forward by an air shower, the rolling roller 12 comes into contact with the upper surface of the powder bag 1. If the upper and lower surfaces of the powder bag 1 are flat, the powder bag 1 will proceed smoothly. As shown in the figure, when the raised portion 15 is on the upper surface of the powder bag 1, the surface is flattened by the rolling roller 12, and the raw material distribution is uniform in the powder bag 1.
[0024]
If the raised portion 15 is high, the powder bag 1 cannot be advanced due to being caught by the pressure roller 12, but the air in the air cylinder 17 is automatically released by the pressure of the powder bag 1. The roller 12 can roll the raised portion 15 without difficulty while rotating in the direction of arrow A.
Since the shutter 13 on the outlet side of the housing is opened at the time of rolling, the powder bag 1 is sent to the outside by the roller conveyor 14 and reaches the standby space between the bag opening portion 5.
[0025]
As shown in FIGS. 3 to 5, the transfer device 4 is provided with support plates 19 at the lower portions on both sides in the longitudinal direction of the flat rectangular frame 18, and three scrapers 20, 21 and 22 are provided between the support plates 19. The entire transfer device 4 can be reciprocated along the transfer direction of the powder bag 1 by the combination of the rack 23 and the pinion 24.
[0026]
The horizontally long plate-shaped scrapers 20, 21, and 22 are bent at both ends at right angles to form connecting plates 20 a, 21 a, and 22 a, and each connecting plate 20 a, 21 a, 22 a can be rotated to the support plate 19. It is connected to the shaft. The scraper 20 is on the rightmost side in the drawing and faces the standby position of the powder bag 1. The scraper 21 is located substantially at the center of the transfer device 4. Further, the scraper 22 is located on the leftmost side on the side opposite to the scraper 20.
[0027]
Each scraper 20, 21, 22 is rotated between a vertical closed state and a horizontal open state by operation of a cylinder 25 provided corresponding to each connecting plate 20a, 21a, and 22a. . That is, the base of each cylinder 25 is fixed to the support plate 19 in a horizontal state. The upper ends of the connecting plates 20a and 21a of the scrapers 20 and 21 and the rod tip of the cylinder 25 are rotatably connected, and by pulling the rod, a one-dot chain line from the vertical closed state shown by the solid line in FIG. It rotates to the horizontal open state shown in FIG.
[0028]
Further, the scraper 22 rotatably connects the rod tip of the cylinder 25 and the lower portion of the connecting plate 22a, and rotates from the vertical closed state to the horizontal open state by extending the rod. Accordingly, the scrapers 20 and 21 and the scraper 22 are opened and closed in the opposite direction. In addition, the height position when each scraper 20, 21, and 22 opens horizontally is the height which the powder bag 1 can pass.
[0029]
As described above, the entire transfer device 4 can be reciprocated by the combination of the rack 23 and the pinion 24. Racks 23 provided integrally in parallel with the frame 18 on both sides in the length direction of the frame 18 are placed on a plurality of rotating rollers 27 protruding inward from the external frame 26 surrounding both sides of the transfer device 4.
[0030]
The pinions 24 that mesh with both racks 23 are fixed to both ends of one rotating shaft 28, and the rotating shaft 28 is rotationally driven by a motor 29 that can rotate in the reverse direction. Accordingly, the rack 23 slides on the rotating roller 27 by the rotational drive of the pinion 24, so that the transfer device 4 reciprocates along the transfer direction of the powder bag 1. Since one end of the rotary shaft 28 is connected to the external frame 26 via a bearing (not shown) and the motor 29 is fixed to the external frame 26, the rack 23 and the pinion 24 are not disengaged. The drive motor 29 is controlled by an encoder, can freely set the transfer distance according to the size of the powder bag 1, and reliably transfers the powder bag 1 to the center of the cutter line.
[0031]
The said bag opening part 5 forms the X-shaped cutter line (bag opening line) along the diagonal of the powder bag 1 in the lower surface of the powder bag 1, and demonstrates a detail according to FIG. 6 thru | or FIG. To do.
As shown in FIGS. 6 and 7, the bag opening unit 5 includes a cutter table 30 installed in parallel with the transfer surface of the powder bag 1 and a bag opening mechanism 31 installed below the cutter table 30. . An X-shaped cutter groove 32 is formed on the cutter table 30, and the powder bag 1 is placed on the upper surface of the cutter groove 32 on the cutter table 30.
[0032]
The bag opening mechanism 31 includes a known rodless cylinder 33, a cutter 34 that can reciprocate in the horizontal direction along the rodless cylinder 33 and that can move up and down itself, and a rodless cylinder 33 that pivots on a pivot 35. And a cylinder 36 that pivots around the center.
[0033]
Usually, the rodless cylinder 33 is located in a direction orthogonal to the transfer direction of the powder bag 1. That is, in FIG. 7, the powder bag 1 is sent from the X arrow direction. When the powder bag 1 is transferred, reaches a predetermined position and stops, the rodless cylinder 33 is turned by the cylinder 36 and is parallel to one linear cutter groove 32a of the cutter groove 32 forming the X-shape (FIG. 7). Indicated by a two-dot chain line).
[0034]
The turning shaft 35 is located immediately below the intersection of the cutter grooves 32. When the rodless cylinder 33 is parallel to the cutter grooves 32a, the cutter 34 is located below the end of the cutter grooves 32a. In this state, for example, if the cutter 34 is raised by the lifting cylinder 37, the cutting edge will pierce the lower surface of the powder bag 1.
[0035]
If the cutter 34 is moved along the rodless cylinder 33 with the cutting edge pierced into the powder bag 1, a cutter line having the same length as the entire length of the cutter groove 30 a is formed on the lower surface of the powder bag 1. Similarly, if the rodless cylinder 33 is swung so as to be aligned with the other cutter groove 32b and the lower surface of the powder bag 1 is cut by the cutter 34, an X-shaped cutter line is formed on the lower surface of the powder bag 1. It will be.
Since the cutter groove 32 has such a small width that the cutting edge of the cutter 34 passes, the raw material does not spill from the cutter wire.
[0036]
In addition, the cutter knife 34 can use the ultrasonic cutter knife which does not generate | occur | produce paper dust other than a normal knife. In addition, the rodless cylinder 33, the lifting cylinder 37, etc. may be replaced with cylinders using known ball screws.
[0037]
After forming the X-shaped cutter line (bag opening line) on the lower surface of the powder bag 1 as described above, the powder bag 1 is sent to the next discharge unit 6. The discharge unit 6 is a sealed space independent of the housing as with the cleaning unit 3 described above, and a mounting table 38 for the powder bag 1 is installed at the same plane height position as the cutter table 30. Further, a holder 39 for the powder bag 1 is provided above the cylinder 40 so as to be movable up and down.
And the entrance / exit of the powder bag 1 is provided in the both sides of the housing, and it opens and closes normally by the shutter 41. FIG.
[0038]
When the powder bag 1 having the lower surface opened in an X shape as described above is placed on a predetermined position of the mounting table 38, the holder 39 is lowered by the cylinder 40. The holding tool 39 grips the upper surface of the powder bag 1 and holds it in a hollow state. Therefore, as shown in FIG. 9 and FIG. A plurality of pairs are provided along the vertical direction.
[0039]
A holding claw 42 having a substantially semicircular shape formed by cutting a part of the annular body is fixed to a rotating shaft 43 at the center, and the rotating shaft 43 can be rotated forward and backward by a rotating cylinder 44. Usually, the tip of the holding claw 42 that faces downward is located above the powder bag 1, and the tip of the powder bag 1 placed in a flat shape as shown by the arrow A from the inside to the outside, that is, the arrow A is shown. It rotates from the upper surface toward the long side.
[0040]
Therefore, if the holding tool 39 is lowered by the cylinder 40 and the tip of the holding claw 42 is pressed against the upper surface of the powder bag 1 and the holding claw 42 is rotated outward, the tip of the holding claw 42 pierces the powder bag 1. It protrudes to the upper surface of the powder bag 1 through the inside. Since the powder bag 1 is held in a state of being hooked by the left and right pairs of holding claws 42 being pierced into the powder bag 1, the holding tool 39 may be raised by the cylinder 40. Since the cutter wire is pushed and spread by the weight of the raw material filled in the powder bag 1 by the raising of the holding tool 39, the raw material falls.
[0041]
The mounting table 38, which is normally horizontal, has two base plates that are separable at the central portion, and one end portion is pivotally supported by the housing, as shown in FIG. The chute is configured to open downward by operating a cylinder 45 connected to the base plate.
[0042]
If the placing table 38 is opened at the same time as the powder bag 1 is lifted by holding the holding tool 39, the placing table 38 serves as a chute to guide the raw material to the lower hopper 46. When the raw material is dropped, the doorway is closed by the shutter 41, so that the raw material is not scattered outside. When the discharge of the raw material is finished, the shutter 41 on the outlet side may be opened to take out the empty bag. When the raw material is discharged from the powder bag 1 in the hollow portion, the powder bag 1 may be blown or air may be injected from the hose so that the raw material does not remain in the powder bag 1.
[0043]
When the discharge of the raw material in the powder bag 1 is completed by the above operation, each holding claw 42 rotates in the direction opposite to the above, so that the holding claw 42 comes off from the upper surface of the empty bag, and the empty bag is horizontally closed. It falls by its own weight on the table 38.
[0045]
Transfer of powder bag 1, cleaning and sizing, opening of bag (formation of cutter line), discharge of raw materials, discharge of empty bags, etc. are all controlled by a computer and automatically and continuously processed. In particular, in order to send the powder bag 1 in the standby position to the bag opening unit 5 and to send the powder bag after the bag opening to the discharge unit 6, the transfer device 4 is intermittently continuous. Done by work.
[0046]
Next, the intermittent continuous transfer of the powder bag 1 by the transfer device 4 will be described with reference to FIGS.
The transfer device 4 having the above-described configuration is usually located above the bag opening portion 5 and the discharge portion 6. As shown in (a), when cleaning and bag finishing are completed and the powder bag 1 reaches the standby position, the pinion 24 is driven by the motor 29, the rack 23 is run, and the transfer device 4 is passed through the outer frame 26 to the powder bag. 1. Move forward in the waiting direction of 1.
[0047]
At this time, since at least the scraper 20 is opened upward, the powder bag 1 in the standby position as shown in (b) is accommodated in the transfer device 4. Next, when the scraper 20 is closed and the transfer device 4 is moved back to the original position, the powder bag 1 is moved to the upper part of the bag opening portion 5 by the scraper 20 and stopped as shown in (c). This stop position is directly above the cutter groove 32. To stop the transfer device 4 at the forward position, stop at the reverse position, etc., the motor 29 may be stopped by detection of the sensor, and these operations are automatically managed by the computer as in other operations.
[0048]
Since the next powder bag 1 has been sent to the standby position as shown in (D), if the transfer device 4 opens the scrapers 20 and 21 and moves forward, the first powder bag as shown in (E). 1a and the next powder bag 1b enter the transfer device 4. If the scrapers 20 and 21 are closed in this state, and the transfer device 4 is moved back to the original position, the powder bag 1a enters the discharge part 6 and the powder bag 1b passes through the opening part 5 as shown in FIG. Will be located on top. For this reason, the shutter 41 on the inlet side of the discharge unit 6 is open.
[0049]
The first powder bag 1a is discharged, and the powder bag 1b is opened simultaneously. At this stage, since the next powder bag 1c is sent to the standby position as shown in (g), if the transfer device 4 is advanced with all the scrapers 20, 21 and 22 opened, ), The powder bag 1b and the powder bag 1c are located in the transfer device 4, and the first powder bag 1a (empty bag) is left on the mounting table 38 of the discharge unit 6.
[0050]
If all the scrapers 20, 21, 22 are closed in this state and the transfer device 4 is returned to the original position, the empty bag (powder bag 1 a) is pushed out to the scraper 22. At this time, since the exit side shutter 41 of the discharge unit 6 is open, the empty bag is discarded outside.
[0051]
And the powder bag 1b will be located in the discharge part 6, and the powder bag 1c will be located on the bag opening part 5, and each processing is performed simultaneously.
Since the new powder bag 1d is in the standby position, if all the scrapers 20, 21, and 22 are opened and advanced, the same state as described above (h) is obtained. The bag 1 is opened, the raw material is discharged, and the empty bag is discarded intermittently.
[0052]
That is, the scraper 20 has a function of feeding the powder bag 1 at the standby position to the opening portion 5, and the scraper 21 has a function of feeding the opened powder bag 1 to the discharge portion 6. The scraper 22 has a function of sending out an empty bag from which the raw material has been discharged.
[0053]
【The invention's effect】
As described above, according to the present invention described above, the powder bag 1 whose orientation in the transfer direction is adjusted by the alignment unit 2 cleans the dust adhering to the outer surface in the sealable bag sorting unit 3 by air jet, Since it sucks into the external dust collector, the powder bag 1 can be sent to the next process in a clean state. Moreover, since the outer shape of the powder bag 1 is adjusted by the rolling mechanism, the upper and lower surfaces of the powder bag 1 are in a flat state, and the transfer process can be performed smoothly.
[0054]
The transfer device 4 can send the powder bag 1 after cleaning to the opening portion 5 by the scrapers 20 and 21 that can be opened and closed, and can send the powder bag 1 after opening the bag to the raw material discharge portion 6, Since the empty bag after the discharge of the raw material can be discharged to the outside, it is possible to automatically process the feeding of two powder bags 1 and the sending of one empty bag at the same time. Therefore, operations such as cleaning, opening, discharging, and discharging of the powder bag 1 can be continuously performed mechanically, and the processing efficiency can be improved.
[0055]
Moreover, since the powder bag 1 is placed at a predetermined position by the transfer device 4, an X-shaped bag opening line is formed on the lower surface of all the powder bags 1 in a state determined by the cutter knife 34. In FIG. 4, since a predetermined portion of the powder bag 1 is grasped by the holding claws 42, when the powder bag 1 is lifted, an average pressure is applied to the lower surface of the powder bag 1, and the triangular shape is formed by the bag opening line 4 Since the bags are opened at the same time, the raw material is discharged at a time. In addition, the raw material adhering to the inner surface of the powder bag 1 is peeled off by the discharge vibration of the raw material.
