DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a packer device for granular materials, particularly to a packer device for granular materials suitable for bagging grains.

<Prior art and problems> A long, flat film-like tube is cut and sealed into a certain longitudinal dimension to form a bag of a certain size, and then a certain amount of powder or granules is put into the cough bag. BACKGROUND ART A packer device for packing powder and granular materials into bags is conventionally known.

However, in conventional packer equipment for powder and granular materials, all mechanisms such as the bag-making mechanism for cutting tubes were fixed, so it was necessary to change the type (size) of the tube set in the puff car equipment. For example, when removing a previously set small-width tube and replacing it with a wider tube to form a larger bag, the length to be cut and sealed ( Since the position (R) also changes, the position of the bag-making mechanism, etc. must be changed each time, which is very troublesome. Therefore, it is fine to bag a certain amount of powder or granular material continuously using only one size of tube, but it is better to bag various amounts of powder or granular material using multiple types of tubes. In the case of high-variety, low-volume production, work efficiency inevitably decreases.

The present invention has been made with attention to such conventional techniques, and it is an object of the present invention to provide a packer device that can solve the above-mentioned problems.

<Means for Solving the Problems> In order to achieve the above object, the packer device for powder and granular material according to the present invention has a structure in which a long flat film-like tube, which is carried in a longitudinal direction, is placed in a predetermined position. Each time, the machine cuts the longitudinal dimension from this predetermined position and seals the bottom, and then uses a bag-making device to form a bag of a predetermined size, and feeds the powder into the bag formed by the bag-making device. A packer device for powder and granular material is comprised of a powder and granular material input device that seals an opening by the bag making device; A bag size determination sensor mechanism that is flexible and detects pinches between marks preprinted on the edge of the tube and determines the longitudinal dimension from the predetermined position; and a signal from the bag size determination sensor mechanism. a cutter for cutting the tube according to the longitudinal dimension, a heat-sealing body for bottom sealing, a sensor mechanism for determining bag size, a cutter, and a moving means for moving the entirety of the heat-sealing body in the longitudinal direction of the tube; moved by this moving means; a bag-making mechanism that is provided with a guide belt that follows the movement of the cutter and heat-sealing body and constantly forms a guide surface for carrying in the tube at the entry and exit sides of the cutter and the heat-sealing body; A suction pad mechanism that suctions the vicinity of the opening of the bag from both front and back sides, and an air nozzle mechanism that blows air toward the opening of the bag suctioned by the suction pad mechanism, The device includes: a chute mechanism for introducing powder and granular material, which is equipped with a variable input port whose opening amount can be adjusted according to the width size of the bag; and a chute mechanism that connects the opening of the bag formed by the bag making device to the chute mechanism. a swing arm mechanism that transfers the powder particles to the lower side of the variable inlet opening and sets them in the upright position; an expander mechanism that uses the expander claws and a temporary presser body to apply tension near the sealing area that is planned to open the bag; After the body is loaded, a sealing means seals the opening of the bag, and the loading position of the receiving plate is determined for each bag size by pulse control corresponding to the signal from the bag size discrimination sensor mechanism. The bag is provided with a pedestal mechanism whose position is constant and whose receiving plate is inclined in order to transfer the bag to another at this transfer position.

<Embodiment> Hereinafter, a preferred embodiment of the puff car device for powder or granular material according to the present invention will be described based on the drawings.

The size of the bags 5 used for bags (bags) is limited to a certain number of types, from 1 kg to 5 kg, 510 kg, and 15 kg, and tubes 4 of width size W depending on each type are used. The tube 4 is then cut and sealed at regular length intervals to form the various bags described above, and the length of the tube 4 to be cut is uniquely determined according to the width W of the tube 4. be done. Marks 9 are printed on the edge portion 7 of the tube 4 at fixed positions in the width direction (Z direction in the figure) from the edge 8 of the tube 4 at pitches P corresponding to the length in the longitudinal direction to be cut. There is. That is, as long as the pitch P between the marks 9 is known, the longitudinal dimension and the width size W can be automatically determined, so that the size of the bag 5 to be formed can be determined. This mark 9 is detected by an optical sensor 10 as a "bag size discrimination sensor mechanism" to be described later, and other mechanisms such as the bag making device 2 are controlled by a signal (information) corresponding to the size of the bag 5 to be formed. (See Figures 1 and 2). Incidentally, the size of the bag 5 to be formed may be determined by detecting the pitch of both edges 8.

□Bag making equipment□ Next, the bag making device 2 will be explained.

The bag making device 2 includes a take-up roll 11, a bag making mechanism 12, a suction pad mechanism 13, and an air nozzle (air nozzle mechanism) 14.
It is composed of.

Take-up roll (2') 11 is a take-up roll that winds up and stores a tube 4 in the form of a long flat film made of synthetic resin so as to be freely delivered.

12 is the bag making mechanism that moves on the rail 15 in the front and back direction (xSy in the figure)
It is mounted and fixed on a trolley 16 that can freely slide in the direction). This truck 16 is connected to a screw shaft 88 which is rotatably driven by a motor 87 as a "moving means" via a fixed napht 86.
It is connected to and can slide freely. A guide belt 18 with a spring 17 looped around a plurality of rotating rollers is provided before and after the bag making mechanism 12.
are connected to each other so as to follow the movement of the bag making mechanism 12. Therefore, a guide belt 18 is formed in front and behind the bag-making mechanism 12 in a flat state without loosening along the direction of movement thereof, and this flat portion serves as a guide surface (movement reference surface) for the tube 4 as described later. . The tube 4 is guided by the guide belt 18 to be accurately positioned at the entrance of the bag making mechanism 12.

Incidentally, instead of the guide belt 18, convex type belts may be provided before and after the bag making mechanism 12, respectively. Further, the movement of the bag making mechanism 12 is controlled by a signal (information) from a pulse generator 19, which will be described later, and which is built into the bag making mechanism 12.

The structure of the bag making mechanism 12 itself is shown in FIG.

Reference numeral 20 indicates a pair of upper and lower feed rollers.
A plurality of spring belts 21 for feeding the tube 4 are wound around the , and one end of this feeding roller 20 rotates together with the feeding roller 20 and generates a number of pulses corresponding to the amount of rotation of the feeding roller 20. A pulse generator 19 is attached. This number of pulses is used to determine various bag sizes, as will be described later.

22 is a cutter which cuts the tube 4 by sandwiching it between upper and lower blades.

Reference numeral 23 denotes a heat-sealing body, which can weld the tube 4 in the width direction by sandwiching the tube 4 between the lower heating section 24 and the upper receiving section 25 to form the bottom of the bag 5.

Reference numeral 26 denotes a fine needle for making holes, which descends into each gap between the plurality of spring belts 21 to form a plurality of deaeration holes along the width direction of the tube 4.

The vertical movements of the cutter 22, the heat seal body 23, and the fine needle 26 are simultaneously performed by the expansion and contraction of the cylinder 27 disposed below.

Reference numeral 10 denotes an optical sensor, which is composed of an edge detection sensor 90 for detecting the edge 8 of the tube 4 and a mark detection sensor 91 for detecting the mark 9. The mark detection sensor 91 is of a reflective type and is composed of a light emission detection section 28 on the upper side (the side corresponding to the surface of the tube 4 on which the mark 9 is printed), a reflection section 29 and a light source section 30 on the lower side. be.

That is, the light emission detection section 28 optically connected to the light source section 30
The light beam emitted from the tube 4 first passes through the tube 4 and is reflected by the lower reflecting section 29. Then, this reflected light beam passes through the tube 4 again and returns to the original light emission detection section 28, and the mark 9 on the tube 4 is detected by comparing the light amount of the returned light beam with the light emission amount. Further, the edge detection sensor 90 is composed of a light emission detection section 92 and a light source section 93, and detects the edge 8 by detecting the light reflected on the surface of the tube 4. The light emission detection section 28, reflection section 29, and light emission detection section 92 of the optical sensor 10 can be mounted upside down depending on the surface of the tube 4 on which the mark 9 is printed.

The light emission detection unit 28 is located in the width direction of the tube 4 (Z direction in the figure).
It is fixed to a frame 31 that is freely movable. A rack 32 is attached to the lower surface of the frame 31, and when this rack 32 is engaged with a pinion 34 rotated by a motor 33, it can freely move back and forth in the width direction (FIGS. 5 and 6).

The movement and mechanism for forming the bag 5 from the tube 4 by the bag making mechanism 12 as described above will be described later.

Pad structure (Fig. 7 and Fig. 8) Reference numeral 13 denotes a suction pad mechanism, which sucks the vicinity of the opening 35 of the bag 5 formed by the bag making mechanism 12 from above and below (front and back). It will expand the world. 36 is an air cylinder that moves a U-shaped movable frame 37 up and down. Above the movable frame 37, there is provided an erection frame 39 which is biased downward by a spring 38 and is movable up and down, and this erection frame 39 has two upper suction pads 40 and two upper rubber legs. 41 is arranged facing downward. A fixed frame 42 has two lower suction pads 43 corresponding to the two upper suction pads 40, two sliding frame suction pads 44 on the outside thereof, and two lower rubber legs corresponding to the two upper rubber legs 41. 45 are arranged facing upward. These two lower suction pads 43 are arranged with a slight positional shift from each other with respect to the two lower suction pads 40, and can protrude relatively upward from a sliding frame 47 supported by a spring 46. There is. And the sliding frame suction pad 44
is arranged slightly below the lower suction pad 43.

The air nozzle machine f (7th and 8th) 14 is an air nozzle as an "air nozzle mechanism", and the movable frame 3
It is attached to the tip of a swinging arm 48 that swings in synchronization with 7. The center of the swing arm 48 is rotatably supported by the fixed frame 42, and an elongated hole 49 is formed at the other end. A bin 50 provided on the movable frame 37 is slidably engaged in the elongated hole 49. Therefore, the air nozzle 14 rises as the upper suction pad 40 descends, and the upper and lower suction pads 40.
43 clamps and sucks the opening 35 of the bag 5, and at the same time the bag 5
is positioned close to the opening 35 of. Then, air is blown toward the opening 35 to allow the upper suction pad 40 and the upper suction pad 43 to more completely expand the opening 35. In addition, this air nozzle 14
Since the upper suction pad 40 descends as the upper suction pad 40 rises, it does not interfere with the swing arm 51, which will be described later.

□Milled rice charging device□ Next, the polished rice charging device 3 as a "powder charging device" will be explained. This polished rice charging device 3 includes a swing arm 51, a chute 4ffl structure 52 for charging polished rice, an expander mechanism 53, and a pedestal mechanism 55.

Swing arm mechanism (2nd and 9th) The swing arm 51 as a "swing arm mechanism" has a rotation center 56 at the top, and an opening 3 of the bag 5 near the bottom (tip).
A clamping portion 57 is provided for gripping 5. That is, the opening 35 of the bag 5, which has been opened and expanded by the suction pad mechanism 13 and the air nozzle mechanism 14, is pinched and grabbed by the clamping part 57, and rotated as it is, so that the opening 35 of the bag 5 can be opened and opened to make white rice. The bag 5 is transferred to the lower side of the chute mechanism 52 for loading, and the bag 5 is set in an upright position.

A chute (9th and 10th) 52 is a chute mechanism, and a tank (not shown) for holding polished rice 6 is provided above, and a variable input port 5 is provided at the lower end of the chute mechanism 52.
8 is a provision.

The variable input port 58 is composed of a pair of gates 59 having a U-shaped cross section, and the lower ends thereof are rotated by a rotating air cylinder 60 so as to be able to approach and separate from each other. The opening amount of the variable input port 58 changes according to the width size W of the bag 5 by moving the pair of gates 59 closer to each other and away from each other. A bearing 61 is attached to each gate 59. This bearing 61 is connected to the expander mechanism 5 which will be described later.
The opening angle of both gates 59 is regulated by being brought into contact with the third dog 62.

The expander mechanism (11th and 12th) 53 is an expander mechanism, and first, when the polished rice 6 is put in, it is expanded in the width direction (Z direction in the figure) into the opening 35 of the bag 5 held by the clamping part 57 of the swing arm 51. In order to provide tension and facilitate the insertion of the polished rice 6, the opening 35 is formed into an approximately ◇ shape.

Reference numeral 63 denotes two slide pars, which are installed in parallel across the gate 59 of the variable input port 58. Two slide portions 64 are provided. The slide portions 64 are connected to swingable links 66 connected to both ends of the air cylinder 65, and the slide portions 64 slide toward and away from each other in accordance with the expansion and contraction of the air cylinder 65. It is supposed to be done. Expander claws 68 are attached to the slide portions 64 in a hanging state, each of which is bent in a direction toward each other and whose tip portions 67 are tapered. Also,
The tip end 67 of the expander claw 68 has a rough surface and is inclined so as to open outward. Therefore, bag 5
When the tip 67 is inserted into the opening 35 of the bag 5 and the bag 5 is expanded and supported from the inside, the tip 67 comes into close contact with the inside of the bag 5 and becomes difficult to come out from the opening 35 of the bag 5. . Reference numeral 69 denotes an air cylinder for vertical movement, which operates together with the slide par 63, link 66, etc., as well as the expander pawl 68.
It moves up and down. Therefore, this expander claw 68 is movable vertically and horizontally.

A dog 62 is attached to the slide portion 64. The dogs 62 come into contact with bearings 61 provided on each gate 59 of the variable input port 58, and restrict the rotation locus thereof. That is, the opening angle of each gate 59 is regulated via the bearing 61 according to the position of the expander claw 68, and the opening amount of the variable input port 58 is made to correspond to the width size W of the bag 5.

B. Sae [14th x (A) to (C)] 54 is a temporary holding body that clamps the vicinity of the opening 35, which has been brought into a tension state by the expander claw 68, across the width direction of the bag 5, and maintains the tension state. This is to maintain the following.

The heat sealing body 70 as a "sealing means" is composed of a heating part 71 and a receiving part 72, like the heat sealing body 23 in the bag making mechanism 12 described above, and is connected to the chute mechanism 52. This is the part where the opening 35 after the polished rice 6 is put into the bag 5 is clamped and welded and sealed.

Structure (Fig. 2, 15 cutout, Fig. 16) The pedestal 74 of the pedestal mechanism 55 can generate accurate pulses by counting the number of pulses corresponding to the size of the bag 5 using another pulse generator 94. It is designed to move up and down. This pedestal 74 has a receiving plate 73 which can be freely tilted via a hinge 75.
is the installation. This receiving plate 73 supports the bottom of the bag 5 supported by the swing arm 51 at the charging position A when the polished rice 6 is charged into the bag 5. When the addition of the polished rice 6 is finished and the sealing starts, the receiving plate 73 touches the sealing part 85 of the bag 5.
It rises to the sealing position M to completely remove the weight of the polished rice 6 on it. After sealing is completed, it descends to the cooling position N and stops for a predetermined time until the seal portion 85 is completely cooled. Finally, the seal part 85 places the completely cooled bag 5 on it and descends to the transfer side position fiB. At the transfer position B, the bottom of the receiving plate 73 interferes with the roller 76, so that the receiving plate 73 is tilted, and the sealed bag 5 containing the polished rice 6 can be transferred to another position. The height position of the loading position A and the cooling position N of the pedestal 74 in the pedestal mechanism 55 changes depending on the size of the bag 5. On the other hand, the sealing position M is a position raised by a certain number of pulses from the input position A according to the size of the bag 5, and the transfer position B is always kept constant by a positioning stopper 82. ing.

Next, the operation will be explained.

First, a case will be described in which a 10 kg bag 5 is formed and the bag 5 is used to pack white rice 6. The tube 4 sent out from the take-up roll 11 passes through a plurality of guide rollers and is carried into the bag making mechanism 12 while being placed on the surface of the guide belt 18. The optical sensor 10 is activated from the moment the tip of the tube 4 is introduced into the bag making device 2.

First, the edge detection sensor 90 of the optical sensor 10 detects the edge 8 of the tube 4 while moving in the width direction Z of the tube 4.
An edge detection operation is performed to locate the edge. When the edge detection sensor 90 detects the edge 8, it moves further based on the detection position, and this time the mark detection sensor 91 is located on the printing line of the mark 9 on the tube 4.

Therefore, it becomes possible to detect the mark 9 printed in advance on the edge portion 7 of the tube 4 at a fixed position from the edge 8.

Pitch movement of the mark tortoise (1st N) Next, the tube 4 introduced into the bag making mechanism 12 is conveyed by the feed roller 20 in the direction along the edge 8 of the bag 5, that is, along the longitudinal direction, in the feeding direction. Therefore, the mark detection sensor 91 detects each mark 9, and at the same time the pulse generator 19
The number of pulses corresponding to the pitch P between the marks 9 (in this embodiment, 1 pulse corresponds to 11) is counted. That is, at the same time as the mark detection sensor 91 detects the first mark 9a, the pulse generator 19 starts counting pulses □, and the detection of the second mark 9b causes the tube 4
The conveyance (rotation of the feed roller 20) stops, and at the same time, the counting of pulses also stops. Since the pitch P of the mark 9 is printed in advance according to the size of the tube 4, it can be determined from the number of pulses counted at this time that the type of bag 5 to be made is a bag 5 for packing 10 kg. become.

Next, the feed roller 20 reversely rotates by a pitch of 2 minutes to return the tube 4, and the cutter 22 is positioned relative to the first cut line 78a immediately before the first mark 9a, Unnecessary part at the tip where the dimensions are not accurate after cutting (cutting) 8
Cut off 4. This cut end becomes the front end 89 of the first bag 5. Note that this return operation is performed only when a new take-up roll 11 is used and there is an unnecessary portion 84 at the tip whose dimensions are not accurate.

Size corresponding operation (Figures 2 and 3) The signal (number of pulses) corresponding to the tube 4 for packing 10 kg by the pitch P detection operation between the marks 9 is sent to the bag making mechanism 1.
The signal is transmitted to the motor 87 of the truck 16 to which the motor 2 is assembled and the motor of the pedestal mechanism 55.

That is, the bag making mechanism 12 uses the signal from the pulse generator 19 to set the front end position 77 as the "predetermined position" of the bag making device 2.
The tube 4 is moved back and forth while being held between the feed rollers 20 and stopped so that the distance from the to the cutting position matches the longitudinal dimension of the bag 5.

That is, at this point, the position of the bag making mechanism 12 corresponding to the bag 5 for filling 10 kg is determined. At this time, the cutter 22 is positioned to correspond to the cut line 78b of the first bag 5, and the heat seal body 23 is positioned to correspond to the seal portion 79, respectively.

Further, the loading position A of the pedestal 74 (receiving plate 73) of the pedestal mechanism 55 is adjusted to the optimum height for supporting the bottom of the bag 5 for filling 10 kr.

Cutting/Sealing ΦB (Third step) Next, the tube 4 is sent out in the feeding direction by the pitch part (the number of pulses), and the cut line 78b and the sealing part 79 are positioned relative to the cutter 22 and the heat sealing body 23. . At this time, the cut opening (front end 89
) coincides with the front end position 77 of the bag making device 2. When the cylinder 27 is operated, the cutter 22 and the heat sealing body 23 sandwich the tube 4, and at the same time, the silk needle 26 is lowered. A predetermined cut line 78b is cut, and a seal portion 79 is formed.
is sealed (bottom seal in this example) and
A plurality of deaeration holes are made by the fine needle 26 along the seal portion 79 thereof. In this way, the bag 5 into which the white rice 6 is placed and sealed is formed.

Note that this vent hole is for removing internal air after the polished rice 6 is packed into bags. The above is the operation by the bag making mechanism 12.

Opening and Expanding Operation (FIGS. 7 and 8) The bottom-sealed bag 5 has its opening 35 introduced between the upper suction pad 40 and the sliding frame 47. First, the upper suction pad 40 is lowered by the air cylinder 36. At this time, the lower suction pad 43 is located slightly below the sliding frame 47, and even if the bag 5 is introduced, it will not be caught on the upper suction pad 43. The upper suction pad 40 continues to descend, and the upper rubber leg 41 and the lower rubber leg 4
It stops with the sliding frame 47 being sandwiched between it and the sliding frame 47. In this state, the sliding frame 47 is slightly lowered due to the pressing of the upper rubber legs 41, and the upper suction pad 43 is positioned slightly above the upper surface of the sliding frame 47, so that the upper suction pad 43 is securely moved. It is adsorbed into bag 5. Note that this lowered state of the sliding frame 47 is maintained as it is because the sliding frame 47 is attracted by the sliding frame suction pad 44. And rain suction pad 40
．． At 43, a suction operation is performed. After suction, the upper suction pad 40 rises, and the opening 35 of the bag 5 is opened and expanded.

On the other hand, the air nozzle 14 is raised by the rotation of the swing arm 48 as the upper suction pad 40 is lowered, and is positioned close to the opening 35 at the same time as the suction pad 40 is lowered. Then, air is blown into the bag 5 through the opening 35 in order to open the bag 5 more completely in order to facilitate the subsequent insertion of the polished rice 6. Then, it descends as the upper suction pad 40 rises.

Bag opening operation (9'X,) Next, the swing arm 51 rotates to approach the bag making device 2 side, and the opening 35 of the bag 5, which has been opened and expanded, is held by the holding part 57. and grab it. Then, while grasping the opening 35 of the bag 5, the user rotates upward to position and set the bag 5 below the chute mechanism 52 in an upright state. The air nozzle 14 does not interfere with the air nozzle 14 since it has already been lowered when the swing arm 51 comes to pick up the bag 5, and the sliding frame 47 has a notch 80 at a position corresponding to the clamping part 57.
Since this is provided, the gripping portion 57 of the swing arm 51 can grip the bag 5 without interfering with the sliding frame 47.

White 7 (FIG. 9) The bag 5 is set below the chute mechanism 52 by the swing arm 51 with its opening 35 being held open by the holding portions 57. Further, the bottom of the bag 5 is supported by the receiving plate 73 which has been raised to the loading position A. Then, the pair of expander claws 68 are inserted into the inside of the opening 35, and the width is expanded until each tip 67 comes into close contact with the inside of the edge 7 of the bag 5 and stops (until it cannot move due to the elastic force of the bag 5). It slides away in the direction (Z direction in the figure). As a result, even if the position of the bag 5 is slightly misaligned in the width direction, the pair of expander claws 68 are separated and moved to a position corresponding to the width of the bag 5, and are positioned there. Note that the distance between both expander claws 68 in this state is a specific distance depending on the width size W of the container bag 5, and the opening amount of the chute mechanism 52 is determined from this distance as described later.

Due to the separation and movement of the expander claw 68 as described above, the opening 35 of the bag 5 is pulled (expanded) in a direction (width direction Z) that intersects the direction in which it is supported by the clamping part 57. The opening shape becomes approximately ◇ shape, making it easy to put in the polished rice 6.

Next, the variable input port 58 of the chute mechanism 52 is opened, and a predetermined amount of 1 t (+r to 10) of polished rice 6 is input into the bag 5.

At this time, the opening amount of the variable input port 58, that is, the approach/separation angle between the pair of gates 59 is 31.
The angle is automatically adjusted according to the weight (10 kg). That is, since the distance between the expander claws 68 separates and stops at a specific distance corresponding to the width size W of the 10 kg side bag 5, the dog 62 fixed to the slide portion 64 also corresponds to the width size W of the bag 5. They each stopped at their respective positions. Therefore, by means of the bearings 61 whose positions are regulated by contacting the dogs 62, the angles of approach and separation of the gates 59 are also adjusted according to the width W of the bag 5. In the case of this embodiment, the opening amount of the variable input port 58 is 10.
Since the opening is slightly larger for kg, the loading time can be shortened.

, Mo42 (Pe) Color Otsu: 11 works [Figures 11-14 (c)])
After putting the white rice 6 into the bag 5, the opening 35 is sealed, but the bag 5 swells due to the white rice 6 being put in, and the opening 35 becomes uneven. In other words, it becomes full of wrinkles, and if left as it is, it will not be possible to form a perfect airtight seal. Therefore, prior to sealing the opening 35, the expander i+1I53t- is used to make the opening 35 straight and clean, thereby ensuring a perfect seal.

The expander claw 68 of the expander mechanism 53 is inserted into the opening 35 of the bag 5 in advance during the rice charging operation, and when the clamping part 57 of the swing arm 51 leaves the bag 5 after the charging of the polished rice 6 is completed. , slide outward again to separate from each other. Therefore, the opening 35 of the bag 5 is fully expanded from the inside to the width W of the bag 5, so that even though the bag 5 is filled with white rice 6, the opening 35 is straight without wrinkles. Become. At this time, the position of the tip 81 of the expander claw on the 6th day is the bag 5.
Since it is located below the lower end of the intended sealing part 85, complete wrinkle prevention is achieved from the tip 81 to the upper part (including the intended sealing part 85).
Figure 13 (a) and Figure 14 (a)].

Next, the temporary holding body 5 is placed directly below the portion held down by the tip 81 of the expander claw 68 over the entire width direction.
4 holds it. When the temporary holding body 54 clamps the bag 5, both expander claws 68 slide slightly inward,
Stop pushing and expanding the bag 5 and move it upward. In other words,
The tip 81 of the expander claw 68 is not in contact with the inside of the bag 5 and rises as if straddling the seal portion 85, so that it does not damage the inside of the bag 5 when rising (Fig. 13).
b) and Figure 14 (b)].

Then, slide it upward again in the opening direction to open the opening 3.
Press and expand the 5th part from the inside. Then, the temporary holding body 54
The part between the part held between the parts and the opening part 35 which is pushed and expanded by the expander claws 68 (seal part 8
5) will be neatly arranged without wrinkles [Figures 13 (c) and 14 (c)].

Loop Loop Seal Movement A [Figures 13 (C) and 14 (C)] By sandwiching the sealed portion 85 of the prepared bag 5 between the heat sealing bodies 70 in the expander operation described above, the sealed portion 85 is sealed. weld. At the same time as welding begins, the receiving plate 73
rises to the sealing position M, supports the weight of the polished rice 6, and completely removes the weight of the polished rice 6 applied to the sealing part 85. When the welding is completed, the heat sealing body 70 is opened, but the temporary holding body 54 still holds the bag 5.

In other words, after a predetermined period of time has elapsed and the welded seal portion 85 is cooled until it can withstand the tension due to the weight of the polished rice 6,
This allows the temporary holding body 54 to open. As a result, the sealing part 85 is sufficiently cooled without receiving the weight of the polished rice 6 thrown into the rice bowl 10, so that the sealing part 85 is reliably sealed. At this point, the bagging of white rice 6 is completed.

Substitution rotation φ (72° and Fig. 15) When the bagging is completed, the receiving plate 73 descends together with the receiving stand 74 with the bagged white rice 6 placed on it. Then, it is stopped at the cooling position N and the seal portion 85 is further completely cooled. In this cooling position N, the upper part of the sealed bag 5 is located at the swing arm 51.
Since the swing arm 51 is at a height that does not interfere with the rotation locus of the tip of the bag 5, the swing arm 51 can rotate to pick up the next bag 5 at this stage, and the work efficiency is improved accordingly. Then, when it descends again and the pedestal 74 hits the positioning stopper 82 and stops at the transfer position B, the bottom of the receiving plate 73 hits the roller 76 and the receiving plate 73 is tilted. Due to this inclination of the receiving plate 73, the bags 5 that have been filled are separated from the receiving plate 73 and transferred onto the belt conveyor 83 below. Since the seal portion 85 is completely cooled at this time, the seal portion 85 will not burst even if there is a shock due to the transfer.

By repeating the above operations continuously, 10k
You can bag 6g of white rice one after another. When changing the bagging amount to, for example, 5 kg, it is sufficient to simply set a long tube for 5 kg into the puff car device 1. As long as you cum,
After that, the bag making mechanism 2 and the pedestal mechanism 55 are connected via the optical sensor 10.
is positioned at an appropriate position, and the opening amount of the chute mechanism 52 is adjusted via the expander mechanism 53, so the white rice 6 can be packed into bags automatically without any troublesome adjustment or recombination of the mechanism. It can be carried out.

<Effects> Since the puff car device for powder and granular materials according to the present invention has the content as described above, it can produce various effects as described below.

fal The bag size discrimination sensor mechanism moves and controls the bag making mechanism, pedestal mechanism, etc. to the optimal position according to the bag size, so even when using tubes of different widths, there is no need for troublesome adjustments or mechanism changes. There is no need for recombination, and just by setting the tube, powder and granular materials can be packed automatically and reliably into bags.

(bl) Guide belts are integrally attached to the front and rear of the bag-making mechanism, so even if the bag-making mechanism moves, it follows the movement of the bag-making mechanism, so there is no gap between the front and back, ensuring the tube is introduced securely. can guide you.

(C) Since the air nozzle mechanism blows air toward the opening of the bag that has been suctioned by the suction pad mechanism,
Even if the bag is in a close contact state, the opening can be reliably opened and expanded.

(d) Since the chute mechanism changes its opening amount to the optimum size according to the width size of the bag, it is possible to perform the work of introducing powder and granular material reliably and efficiently.

+e) Since the opening of the bag is neatly arranged without wrinkles by the expander mechanism, the sealing operation of the opening becomes easy and a highly sealed seal can be reliably applied.

(f) Since the receiving plate of the pedestal mechanism is adjusted to the optimum loading position in accordance with the tube, the bag can be reliably supported from below when the powder is being loaded.

(Illusion) In addition, the transfer position of the receiver mechanism is always constant regardless of the loading position, making it easy to combine with the next process such as a conveyor or palletizer.Moreover, since the receiver plate is tilted at the transfer position, They can be automatically transferred to the next process.
