Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a filling device that fills a bag with contents that are higher in viscosity and poor in fluidity than ordinary liquids, such as whipped cream, mayonnaise, and negito.
[0002]
[Prior art]
When filling the contents into a bag whose bottom portion is inclined from a horizontal plane using a conventional filling device having a vertically moving filling nozzle, as shown in FIG. 3 , the filling nozzle installed at a position facing the center of the bag mouth N is lowered vertically and inserted from the bag mouth, and is stopped when its tip comes slightly before the inclined surface of the bag bottom. That is, the tip of the filling nozzle can be inserted only at a position away from the triangular corner (acute corner) at the bottom of the bag. Then, the discharge of the contents is started at that position, and the filling nozzle N is raised as the contents accumulate in the bag (the hatched portion in the bag schematically shows how the contents accumulate in order). To show).
At this time, if the contents are high in viscosity and poor in fluidity as described above, the contents coming out from the tip of the filling nozzle and contacting the inner surface of the bag lose more fluidity, and the corners of the triangle shape not go entered into, there to fill in a state in which the air a remaining is complete.
[0003]
[Problems to be solved by the invention]
It was difficult to deaerate the air remaining at the corners on the acute angle side of the bag bottom in a subsequent process, and as a result, the deaeration state was poor and the quality of the product was significantly reduced.
Accordingly, an object of the present invention is to provide an acute angle corner portion of a bag bottom when filling a bag with a high-viscosity content from a bag opening that is gripped on both edges by a gripper and whose bottom is inclined upward from a horizontal plane. It is intended to reduce the amount of air remaining in the air.
[0004]
[Means for Solving the Problems]
The present invention grips and hangs both edges in the bag width direction with a gripper, the bag mouth opens upward, the bottom part is inclined from the horizontal plane between both edges, and an acute angle is formed between the bottom part and one edge part. corner inserts the filling nozzle from the bag mouth of the bag which is formed, in a filling device for filling into the bag by ejecting high contents viscosity from the tip, the filling nozzles are installed vertically movably, In addition, as the elevating and lowering, the tip of the filling nozzle is displaced in the bag width direction so as to substantially follow the center of the space in the bag from the acute corner to the bag mouth .
[0005]
As a more specific configuration, in the filling device according to the present invention, the filling nozzle can be moved up and down and tilted as it moves up and down, and the center of tilting is displaced in the direction of tilting as it moves up and down, and at the same time, the tip is the direction of tilting. It is set so as to be displaced in the opposite direction, and further, as it descends, the tilt amount of the filling nozzle and the displacement amount of the tilt center increase, and the displacement amount of the tip thereof increases. Alternatively, the filling nozzle is installed so as to be able to move up and down, and the filling nozzle is set so as to be displaced in the bag width direction along with the raising and lowering, and the displacement amount of the filling nozzle is increased as it is further lowered.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1 and 2, illustrate the present invention.
A filling device 1 shown in FIG. 1 is installed at a content filling position in, for example, a well-known intermittent rotation table type bagging and packaging machine, and discharges a high-viscosity content. It comprises a device 3 and a tilting device 4 for tilting the filling nozzle 2.
The lifting / lowering device 3 includes a lifting / lowering shaft stand 6 erected on the machine base 5, a lifting / lowering shaft 7 guided and driven at a predetermined timing by a driving source (not shown) in the machine base 5, and a nozzle support fixed to the tip portion thereof. The arm 8 and the nozzle support arm 8 include an operation link 10 that is pivotally supported by a shaft 9 at a tip end portion thereof.
[0007]
The tilting device 4 includes a nozzle holding member 11 fixed in the middle of the filling nozzle 2, and shafts 12 and 13 fixed so that the axial centers coincide with both sides of the nozzle holding member 11 (the shaft 12 is a lower end of the operation link 10. A bearing member 14 that rotatably supports the shaft 13, a slide unit 15 fixed thereto, and a slide rail 16 on which the slide unit 15 slides, and the filling nozzle 2 A cam roller mounting member 17 fixed to the upper end of the cam roller, a cam roller mounting shaft 18 fixed thereto, a cam roller 19 rotatably supported on the cam roller 19, a cam 20 on which the cam roller 19 rolls, and a biasing force to the cam 20 And a base plate mounting stand 22, a base plate 23, and the like standing on the upper surface of the machine base 5. The slide rail 16 and the cam 20 are fixed to the base plate 23 at an angle.
A filling hose 24 is attached to the side surface of the filling nozzle 2, and this filling hose 24 is connected to a supply tank (both well-known, not shown) via a valve, a cylinder, and the like.
[0008]
By the way, if the contents are high in viscosity and poor in fluidity, the contents coming out from the tip of the filling nozzle 2 and contacting the inner surface of the bag lose further fluidity, so that air is not left in the bag as much as possible. In order to achieve this, the tip of the filling nozzle 2 is inserted so that it is deep in the space of the triangular corner (acute corner) in the bag and located substantially at the center of the space. It is desirable to distribute evenly. Even in the process of ascending while discharging the contents into the bag, it is desirable that the tip of the filling nozzle always rises so as to substantially follow the center of the space in the bag. This is because the tip of the filling nozzle 2 is inserted so that the tip of the filling nozzle 2 is substantially located on the bisector a, where a is a triangle bisector in FIG. 1 and b is the left and right center line of the bag. It may be said that when rising, it rises substantially along the bisector a, and then rises substantially along the left and right center line b.
[0009]
On the other hand, in this filling apparatus 1, the filling nozzle 2 is in a standby position indicated by a solid line in FIG. 1 until the bag W gripped on both edges by the gripper G is rotated to the filling position. Stands vertically and its tip is at a position (on the center line b) that faces the center of the bag mouth slightly above the bag W.
Here, when the elevating shaft 7 is lowered, the filling nozzle 2 is lowered via the nozzle support arm 8, the link 10, the nozzle holding member 11, etc., and at that time, the cam roller 19 rolls along the cam 20 and slides. The unit 15 slides along the slide rail 16. As a result, as shown by the phantom line in FIG. 1, the filling nozzle 2 is displaced in the tilting center (position of the shaft 12) in the tilting direction (left in FIG. 1), and at the same time, the tip is opposite to the tilting direction. displaced (right in FIG. 1), further tilting and displacement of the bag width direction of the tilting center is increased, and displacement of the bag width direction of the tip of the filling nozzle as drops is increased. In this filling device 1, since the center of tilting is displaced in the direction of tilting, for example, the tilt of the filling nozzle 2 can be increased compared to the case where the center of tilting is not displaced .
[0010]
By such tilting and displacement when the filling nozzle 2 is lowered, the tip of the filling nozzle 2 is lowered so as to approximately follow the center line b and the bisector a (more precisely, these At the descending end, the tip of the filling nozzle 2 is inserted deeply at the acute-angled corner of the bag W and substantially positioned on the bisector a. At the time of ascent, the contents are discharged and the trajectory is traced in the opposite direction to that at the time of descending, and is extracted from the bag mouth. In addition, in this filling device 1, since the tip (discharge port) of the lowering end of the filling nozzle 2 and the rising end thereof are always oriented substantially in the direction of the bisector a and the center line b, the discharged content Things are evenly distributed to the left and right.
The hatched portion in the bag schematically shows how the contents accumulate in order, but air A remains at the very tip of the acute angle corner as described above, but the remaining amount is smaller than in the conventional case. It can be greatly reduced.
[0011]
In the above example, the slide rail 16 and the cam 20 have a linear shape and are fixed to the base plate 23 in an angular relationship as shown in FIG. By appropriately changing, the locus of the filling nozzle 2 can be made closer to the bisector a and the center line b. Further, if the mounting angle of the slide rail 16 and the cam 20 can be changed, the locus of the filling nozzle can be adjusted in accordance with the change in the size or shape of the bag W.
[0012]
The filling device 31 shown in FIG. 2 includes a filling nozzle 2 that discharges a high-viscosity content, a lifting device 32 that raises and lowers the filling nozzle 2, and a lateral displacement device 33 that displaces the filling nozzle 2 laterally (in the bag width direction). Therefore, it has the same structure as the filling device 1 except for the lateral displacement device 33 (the same number is given to the equivalent portion). The lateral displacement device 33 includes nozzle holding members 34 and 35 fixed at a distance in the vertical direction near the upper end of the filling nozzle 2, and a parallel link support member fixed at a distance in the vertical direction near the upper end of the lifting shaft stand 6. 36, 37, a pair of parallel links 38 to 41 having one end pivotally supported by the parallel link support member and the other end pivotally supported by the nozzle holding member (the link 38 is an operating link) 10 is connected to the lower end of the pin 10 via a pin 42).
[0013]
In this filling device 31, the filling nozzle 2 always stands vertically, and is in a standby position indicated by a solid line in FIG. 2 until the bag W gripped on both edges by the gripper G is rotated to the filling position, and its tip is It is in a position facing the center of the bag mouth slightly above the bag W.
Here, it swings parallel link 38-41 is downward when lowering the elevating shaft 7, as shown in phantom lines in FIG. 2, the filling nozzle 2 is displaced with bag width direction downward, as further lowered The displacement amount of the filling nozzle 2 in the bag width direction is large.
[0014]
By filling nozzle 2 is such displacement when descending, the tip of the filling nozzle 2 is lowered along approximately the center line b and the bisector a (see FIG. 1) (more precisely The upper end of the filling nozzle 2 is deep at the acute corner of the bottom of the bag W and substantially on the bisector a. Inserted into. At the time of ascent, the contents are discharged and the trajectory is traced in the opposite direction to that at the time of descending, and is extracted from the bag mouth.
The hatched portion in the bag schematically shows how the contents accumulate in order, but air A remains at the very tip of the acute angle corner as described above, but the remaining amount is smaller than in the conventional case. Can be greatly reduced. However, during the descending end of the filling nozzle 2 and ascending from it, the tip (ejection port) does not face the direction of the bisector a, so that the ejection is performed particularly in the triangular area at the acute corner of the bag bottom. The filling device 1 is slightly superior in the uniformity of the distribution of the left and right contents.
[0015]
【The invention's effect】
According to the present invention, when the bag is filled with high-viscosity contents, the amount of air remaining at the acute-angle corner of the bag bottom can be greatly reduced, so that the quality of the product does not deteriorate.
