Description

[Detailed description of the invention] This invention facilitates the storage, shipping, and transportation of powder and granule filling bags.
This invention relates to a vibrating shaping conveyor that compacts the contents of a filling bag and shapes it into a flat shape for easy processing.

Powder-filled bags that are porous and breathable may cause various problems such as the powder leaking out of the bag or moisture entering the bag, causing solidification and deterioration of the contents, and this should be avoided. Therefore, if the bag is made of non-breathable material, air will remain inside the bag when the contents are filled and sealed, causing a bulge and making it impossible to form the bag satisfactorily. This may cause falls, bursting of the filled bag, and various other problems.

The present applicant has already proposed an effective deaeration device for non-porous powder-filled bags and a vibrating conveyor for compacting the contents in Utility Model Application Publication No. 57-98201 and Utility Model Application Publication No. 57-11001, etc. However, the present invention was developed to further ensure flattening of the filling bag.

That is, an object of the present invention is to provide a vibrating shaping conveyor that can effectively and reliably compact the contents of a non-porous powder-filled bag and flatten the bag.

The powder filling bag vibrating shaping conveyor according to the present invention has a first position on one side edge of the conveyor that is parallel to the conveying direction and kept in an inclined state with the upper side extending outward from the upper surface of the conveyor with respect to the vertical plane. , an inclined plate capable of swinging in the transfer direction on the conveyor while maintaining the inclined state, and swingable between a second position perpendicular to the transfer direction;
a drive device for swinging between the position and the second position;
The conveyor is disposed at a position facing the inclined plate on the edge opposite to the first side edge of the conveyor (filling is carried out by pushing the upper part of the filling bag, which is transferred in an upright position facing the inclined plate, toward the inclined plate). A pressing device for inverting the bag onto the inclined plate, and a conveyor actuated at a second position of the inclined plate to vibrate the filled bag placed horizontally on the conveyor away from the inclined plate, thereby producing filled bag granules. A diaphragm device is provided below the conveyor mounting surface so as to tighten the granules in the filled bag, and the distance between the conveyor mounting surface and the diaphragm device disposed above the conveyor is gradually reduced to tighten the packed bag granules. The present invention is characterized by a plurality of pressing rollers that sequentially reduce the thickness of the filled bag.

With the above-described structure, the filled bags that are sequentially transferred on the conveyor in an upright state are inverted onto the inclined plate by the pressing device, and when the inclined plate is swung on the conveyor, the bags are transferred onto the conveyor by the transfer movement of the conveyor. It is placed horizontally, and while the contents are made tighter and the lower surface is flattened by the diaphragm device, the pressure roller on the upper side is pressed sequentially to reduce the thickness, and the upper surface is flattened to the appropriate thickness. This is what was done.

Preferred embodiments of the present invention will be described below with reference to the drawings.

The conveyor 1 used in the present invention is hung over a driving pulley 3 and a driven pulley 4 that are rotatably supported by a frame 2, and is guided by guide rollers 5 to define a loading surface 1a. The drive pulley 3 is driven by a drive motor 7 via a belt or chain 6, and moves the mounting surface 1a from the upper garment to the left in the drawing.

A non-ventilated bag is filled with powder and granules, properly deaerated and sealed, and the filled bag 8 is conveyed upright on the conveyor 1 one after another from the right end.

In order to horizontally place the filled bags 8 on the conveyor 1, the present invention is provided with an inclined plate 9 and an extrusion device 10 placed opposite to the inclined plate 9.

The inclined plate 9 is fixed to a pivot lever 12 rotatably supported on a pivot shaft 11, and extends parallel to the conveying direction of the conveyor 1 at one side edge of the conveyor 1, i.e., the first
The first position is located in the upper part of the figure and is tilted and held so that the upper side expands outward from the conveyor 1, and the first position is swung on the conveyor 1 by 90 degrees clockwise in Figure 1 from this position. The arm 12a is fixed to the pivot lever 12, and has a circumferential position defined by a suitable stopper (not shown). A piston rod 14a of a fluid-operated cylinder-piston device 14, which is pivoted on a support plate 13 fixed to the frame 2, is pivotally connected to the lever 12, and thus the inclined plate 9, by actuation of the cylinder-piston device 14. It is adapted to be swung between a first position and a second position.

The extrusion device 10 is disposed on the other side edge of the conveyor 1 opposite to the inclined plate 9, and has a guide member 1 fixed to the frame 2.
a pusher bar 17 mounted on a guide rod 16 which is guided horizontally within the frame 5 so as to be reciprocating at right angles to the transport direction of the conveyor 1 and arranged parallel to the transport direction of the conveyor 1; The piston rod 18a is parallel to the guide rod 16 of the cylinder piston device 18, and the piston rods 1, 8a are fixed to the extrusion bar 17, and when the piston rod 18a is moved by the operation of the cylinder piston device 18, the extrusion bar 17
is pushed out, and as shown in the first figure, when the filling bag 8 (shown in the actual state), which is sent from the right end to the left on the conveyor 1 in an upright state, comes to a position opposite to the inclined plate 9, the upper part of this to push it down onto the inclined plate 9.

Thereafter, when the cylinder piston device 14 is operated, the inclined plate 9 is swung to the position indicated by the chain line in FIG.
' (indicated by a chain line in FIG. 2) is slid down from the inclined plate 9 by the conveyance movement of the conveyor 1, and is placed horizontally on the conveyor 1 as shown by 8'' in FIG.

A guide culm 19 is provided on the conveyor 1 to guide the filling bags 8'' placed horizontally so that they do not fall off both sides of the conveyor 1.

A diaphragm device 20 is disposed adjacent to the lower side of the mounting surface 1a of the conveyor 1 in order to vibrate the horizontally placed filling bag 8'' to tighten the contents.

The diaphragm device 20 includes a diaphragm 22 pressed by a frame 2 by a spring 21 so as to be in contact with the lower side of the mounting surface of the conveyor 1, and a vibrator 23 of an appropriate type attached to the lower surface of the diaphragm 22. The diaphragm 22 is vibrated by the operation of the vibrator 23, and the vibration is transmitted to the filling bag 8'' placed horizontally on the conveyor 1 through the mounting surface of the conveyor 1, and the contents are tightly packed. The lower surface is flattened.

A pressing roller 2 is used to press the filling bag 8'' which has been made tighter from above to gradually reduce the thickness of the filling bag 8''.
4 and 25 are provided.

Press roller 2 on the upstream side of the conveyor 1 in the transport direction
4 has a smaller diameter than the pressure roller 25 on the downstream side.

The shafts 24a, 25a of the pressure rollers 24, 25 are rotatably supported by the intermediate portions of a pair of support levers 26, 27, respectively, with the support levers 26 facing toward the other roller.
, 27 are mounted on a drive shaft 29 which is rotatably supported by the frame 2 by a bearing 28 (this is rotatably supported, and the opposite end is connected by connecting members 30 and 31 to support a pressure roller). A spring support frame 32 implanted in the frame 2 is loosely fitted into holes formed in the tongue pieces 26a, 27a which form the case and are fixed to the respective levers, and the tongue pieces 26a,
A spring 33 is disposed around the part of the support frame 32 that extends upwardly through the support frame 27a, and the upper end is fixed by an adjustment nut 34, and the tongue pieces 26a, 2 are fixed by the action of the adjusted spring 33.
7a is elastically pressed downward, and the tongue pieces 26a, 27a are stopped by the stoppers 32a provided on the respective support frames 32, thereby defining the lower limit positions of the respective levers 26, 27, thereby causing the respective pressing rollers to Spacings a, b between 24 and 25 and the conveyor 1 are defined.

As is clear from Fig. 2, the interval a is larger than the interval,
When the filling bag 8'' passes under the rollers 24, 25, it is pressed one after another and its thickness is successively reduced.

A pulley 35 provided on the drive shaft 29 for rotationally driving each roller 24, 25, a drive pulley 3 on which a belt or chain 6 is stretched, one pulley 36, and a pulley 37 coaxially fixed together. A belt or chain 38 is stretched between them so that the drive pulley 3 and the drive shaft 29 are simultaneously rotated by the motor 7.

A gear 39 is fixed to the protruding end of the drive shaft 29 opposite to the end on which the pulley 35 is fixed, and this gear 39 is a gear 40 fixed to the shafts 24a and 25a of the pressure rollers 24 and 25. , 41, and rotation of the drive shaft 29 causes the pressure rollers 24, 25 to rotate clockwise in FIG.

The circumferential speed of these rollers 24, 25 is determined by the pulley 35,
37 and gears 39, 40, and 41, the transfer speed is set slightly lower than the transfer speed of the conveyor 1.

When the filling bag 8'' is pressed by the rollers 24 and 25, this tends to push the contents back slightly, making the contents tighter, and causing the rollers 24 and 25 to tighten the contents excessively, causing the filling bag to become tighter. This is to prevent damage or damage to the

At this time, the roller 24 is
, 25 are elastically moved by the rollers 24, 25 by the spring 33.
This prevents damage to the filling bag due to excessive pressing force.

In the above description, the roller 25 has been described as being larger than the roller 24, but rollers of the same shape can also be used by appropriately changing the axial position.

However, considering the rolling technology, it is clear that a pressure roller with a small diameter is advantageous in order to advantageously reduce the thickness of the filled bag at the beginning, and subsequent rollers are of a large diameter for the purpose of uniformly smoothing the thickness. It is also clear that the diameter is advantageous.

Furthermore, in the above description, the number of pressure rollers is two, but the number is not necessarily limited to two, and any number of pressure rollers can be used.

The operation of the vibration shaping conveyor according to the present invention constructed as described above is clear from the above description, but will be summarized below.

Powder filling bags are sequentially fed to the entrance side of the conveyor 1, that is, the right end in the drawing, in an upright state as shown in FIG.
When the bag comes to a position facing the bag, the cylinder piston device 18 is actuated by, for example, a photoelectric detector (not shown), and the push bar 17 is pushed out to invert the filling bag onto the inclined plate 9.

After that, the push-out bar 17 is pulled back, and then the cylinder-piston device 14 is automatically actuated by a delay circuit or the like to swing the pivot lever 12 and therefore the inclined plate 9 clockwise to the position shown in chain lines in FIG. The filling bag, which has been placed upside down, is placed horizontally on the conveyor 1 by the transfer movement of the conveyor 1.

After that, the inclined plate 9 is returned to its original position.

The filling bags placed horizontally on the conveyor 1 and transferred are guided by the guide culm 19 and vibrated by the diaphragm 22.
The contents are compressed until they reach the pressure rollers 24 and 25, and while being subjected to the elastic pressing force of the spring 33, the thickness is gradually reduced to a predetermined thickness, and the contents are discharged from the conveyor 1.

It is clear that the cylinder-piston devices 14, 18 can be implemented as other types of drive devices, and the automatic control circuits and the like described above are well known to those skilled in the art and need not be described in detail.
