Description

[Detailed Description of the Invention] This invention relates to the configuration of a bag making and packaging machine, particularly its stand, and its purpose is to facilitate cleaning and loading of bag strips.

Bag-forming and packaging machines, especially those that handle powders, must be cleaned frequently because the powders tend to scatter, and in order to prevent different types of powders from adhering to the bag-forming and packaging machines, the fabric reel around which the bag strip is wound must be cleaned. It was often built into the stand, and replenishing it was complicated.

This invention corresponds to a solution to the above-mentioned drawbacks by adding a new idea to the structure of the platform, and the gist is that the platform is divided along the feeding axis of the bag strip, and one side is made movable. It is something.

This invention will be described in detail below with reference to the illustrated embodiments.

In the illustrated example, a fixed base plate 11 and a movable base plate 12 are placed on a common machine base 13, and the lid-shaped movable base plate 12 collides with the fixed base plate 11 so that it looks horizontally when viewed from the operator side. direction tangent line 1
0, and the lower edge is pivoted 15 to the machine base 13.

A pair of attachment/detachment mechanisms 1 are provided at both ends of the movable base plate 12.
4.14 is installed.

As shown in FIG. 2, each attachment/detachment mechanism 14 has a key-shaped latch 141 pivotally attached to a side piece of the movable base plate 12, and a tip 1411 of the latch 141 to be attached to the machine base 13. It consists of a receiving fitting 142 provided, a spring 143 suspended between the latch fitting 141 and the machine stand 13, and a chain 144 suspended between the side plate and the machine stand 13. is exposed from the top plate of the movable base plate 12 to form an operating section.

Therefore, if the tail end 1412 is pulled toward the operator, the tip 1411
The movable base plate 11 is raised against the spring 143 and detached from the receiving metal fitting 142, so that the movable base plate 11 can be supported and tilted toward the operator (forward) and tilted forward by about 90 degrees.

In order to bring the movable base plate 12 into contact with the fixed base plate 11, the movable base plate 12 is lifted and rotated backwards, and the latch 141 approaches the receiving bracket 142 due to the rotation, so that the tip 1411 of the latch 141 approaches the receiving bracket 142. The movable base plate 12 is fitted into the metal fitting 142 and maintained in this state by the spring 143, that is, the movable base plate 12 collides with the fixed base plate 11 and is locked.

In addition to the illustrated structure, the movable base plate 12 can also have a retractable coupling structure or a snap-on coupling structure, and is provided with an attachment/detachment mechanism 14 suitable for each.In other words, the movable base plate 12 can be moved when necessary. It is important that the structure is such that it can be attached to and detached from the fixed base plate 11, and that the line of contact 10 is formed in a direction transverse to the operator.

Each unit mechanism is arranged so that the contact line 10 between the movable base plate 12 and the fixed base plate 11 becomes the feeding axis of the bag strip.

The first mechanism, i.e., the idle mechanism 2, has a bending line 21 inclined at 45° installed along the collision line 10, and is built into the movable base plate 12 through a slot 16 drilled along the collision line. The bag strip made of heat-fusible material folded in two is pulled up, bent by the folding edge 21, and guided onto the feed axis set along the contact line 10.

The next vertical sealing mechanism 3 is a well-known thermopressure mechanism, in which thermopressure pieces 31 are placed on a fixed base plate 11 so as to face each other on the line of contact 10.
However, the receiving pieces 32 are installed on the movable base plate 12 via pedestals 33 and 34, respectively.

The heat-pressing piece 31 is moved forward and backward by a built-in drive shaft, and a cutting blade is interposed in the center of the heat-pressing part.

This vertical sealing mechanism 3 sequentially forms vertical weld lines (including tear lines) at regular intervals on the bag strip which is intermittently moved when it is stationary, so that each unit of bag body is continuous. This allows partitions to be formed in different states.

Depending on the material of the drop bag strip, the receiving piece 32 may also have a heat-weldable structure.

A filling mechanism 4 is arranged at the next stage on the feeding axis of the bag strip.

The filling mechanism 4 includes a hopper 41 fixed on a fixed base plate 11 and equipped with an elevating mechanism (not shown), and a bag opening pressing mechanism 42.
It consists of

The hopper 41 consists of a funnel 411 and a flat insertion part 412 that is connected to the funnel and can be inserted into the bag body.
1, an appropriate amount of powder (including granules and tablets) is dropped into the bag using a fixed-quantity dropping mechanism (not shown), and the powder is injected into the bag.

The bag opening pressing mechanism 42 includes a pair of stand pieces 421 and 422 facing each other across the feed axis, a pair of press pieces 423 and 424 pivotally attached to each stand piece 421 and 421, and one press piece 42.
3, an advancing/retracting plate 426 located on the back side of the pressing piece 424, and pressing springs 427, 428 inserted between the advancing/retracting plate 426, the leg piece 425, and the pressing piece 424.
As the drive shaft rotates, the advance/retreat plate 426 moves forward and backward, compressing and expanding the push springs 427 and 428. Accordingly, the force applied to the press piece 424 and the leg piece 425 increases and decreases, and the press piece 423 , 424 are moved forward and backward at the same time with respect to the feed axis, and when they move forward, the pressing claws provided at the tips of the pressing pieces 423, 423 are pressed against the outer surface of the insertion portion 412 that is descending. The insertion portion 412 and the bag into which it is inserted are brought into close contact to prevent the powder from scattering to the outside due to blowing up when powder is added.
6 retreats to open the pressing pieces 423 and 424, and the hopper 4
1 will rise and the insertion portion 412 will come out of the bag.

The horizontal sealing mechanism 5 is a mechanism for thermally welding the bag opening of the bag after the powder has been injected.
The structure is similar to that of the vertical sealing mechanism 3 except that the pedestals 53 and 54 are provided horizontally to the bases 53 and 54.

However, since the cutting blade is not necessary, it is not provided. The feeding mechanism 6 is
It consists of a key-shaped frame arm 60 that stands up from the fixed base plate 11 and a pair of feed rolls 61, 62 that hang down opposite to the lower surface of the key-shaped frame arm 60. It is intermittently rotationally driven by a drive shaft via a transmission mechanism extending below, and is intermittently transferred a fixed distance by sandwiching the heat-welded bag mouth edge of the bag strip.

Reference numerals 63 and 64 in the figure are transmission gears forming part of the transmission mechanism, and 7 in the figure is an operation panel having operation buttons.

The guide mechanism 2, vertical seal mechanism 3, filling mechanism 4, horizontal seal mechanism 5, and feeding mechanism 6 described above may all be replaced with known or new mechanisms with the same effect, but in their arrangement, It is necessary to design the feed axis of the bag strip so that it lies along the impingement line 10, ie on it or at a slight distance from it.

According to this invention described above, the movable base plate 12 is replaced by the fixed base plate 11.
When removing the bag strips from the bag, the bag strips are exposed from the frame of the original fabric except for the feeding mechanism 6, so replenishing them is extremely easy, and the bag strips are removed from the vertical sealing mechanism 3 and the bag opening pressing mechanism. 42 and the horizontal sealing mechanism 5 are both separated from the opposing central portions, so each portion can be easily cleaned and maintained in a clean state.

In the delayed feed mechanism 6, since the bag strip can be held between the two feed rolls 61 and 62 from below, the bag strip is not divided, but the advantages described above are not impaired.
