Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a product unloading conveyor in a horizontal bag-making filling and packaging machine such as a horizontal pillow packaging machine, and more particularly to a belt conveyor incorporated in a box motion type heat fusion cutting and sealing apparatus. Regarding

[Prior Art and Problems Thereof] First, an outline of a conventional box motion type heat fusing and sealing apparatus of a horizontal bag-making filling and packaging machine will be described. This device is designed so that the upper and lower heaters perform box motion. Here, the operation of the box motion will be described. With the upper and lower heaters opened vertically, the heaters are closed at the upstream position so as to be aligned with the registration mark of the wrapping paper, and the predetermined distance is moved in synchronization with the speed of the wrapping paper. It is an operation that opens up and down again at the downstream position and returns to the upstream position, and has the advantage that it takes more time to heat seal the wrapping paper than the rotary cutter.

There are various mechanisms for box-moving the upper and lower heaters. For example, both ends of the upper and lower heaters are attached to the connecting links of the double crank mechanism, or both ends of the upper and lower heaters are connected to the front cam ( There is a structure (for example, Japanese Utility Model Laid-Open No. 62-54910) in which a flat circular cam groove of a front cam is rotated by a crank while engaging with a groove cam).

The box motion of the upper and lower heaters means that, on the upstream side and the downstream side of the heater, a conveyor in which the table length is substantially changed in synchronism with the heater in close proximity to the heater is required. At
There are two types that are totally structural, and both are still in use today. One is an endless roller conveyor. That is, an endless transport chain is wound vertically to the left and right, a large number of rollers are hung on the transport chain, and the hangs of rollers are thinned out at regular intervals, so that the space below the thinned space is lower. The structure is such that the heater appears and disappears. The other one is a belt conveyor, in which a conveyor belt is wound around the belt conveying surface so that a gap is opened in the middle of the belt conveying surface, and the gap reciprocates. It is a structure in which the heater on the side comes in and out.

The roller conveyor is cumbersome to assemble, generates a lot of noise, and there are cases where the customer may be disappointed due to the gaps between the rollers.However, the thinning space where the rollers are not suspended extends to the downstream end. Run away downwards,
Even if the packaged product is a short product, a small product, a heavy product, or a bulk product, the packaged product does not drop from the portion where the roller is not provided.

On the other hand, the belt conveyor operates quietly, but if the package is small, the package separated to the table surface on the downstream side when the lower heater is immersed in the gap in the middle of the belt transport surface. Since it has a problem of falling, it cannot be applied to the packaging of small articles. Therefore, there is a device in which when the lower heater is sunk from the table surface, the gap in the middle of the belt conveying surface is closed so that the heater can be applied to the packaging of small articles (Japanese Utility Model Publication No. 49-28133).

However, according to this invention, when operating at high speed, the lower heater rises faster, and the lower heater strongly repels the small roller that closes the gap in the middle of the belt conveying surface. Small rollers have low durability and require short-term replacement. It also becomes a source of noise. Further, since the small roller does not actively feed the packaged product, there is a limit to the size even if it can be used to package short products and small products. However, when it comes to small articles, there is still a problem that the packaged article falls into a gap in the middle of the belt conveying surface. Further, the bottom surface may be damaged depending on the type of the packaged object.

[PROBLEMS TO BE SOLVED BY THE INVENTION] The present invention is directed to lengthening the upstream belt transport surface and the downstream belt transport surface so as to match the reciprocating horizontal motion of the horizontal component of the box motion of the upper and lower heaters of the heat fusing and sealing apparatus. In addition to the change in each of the belt transfer surfaces, when the lower heater is in the lowered position, the gap between the upstream belt transfer surface and the downstream belt transfer surface is substantially eliminated so that the belt transfer surfaces of both belt transfer surfaces are substantially eliminated. An object of the present invention is to provide a belt conveyor for a box motion type heat fusing and sealing device of a horizontal bag-making filling and packaging machine, which can be applied to packaging of short products, small products, heavy products, etc. I am trying.

Hereinafter, each embodiment will be described within a range that does not overlap with the above description of [Means for solving the problem].

[Embodiment of the first invention ... Figs. 1 to 3] First, the configuration of a box motion type heat fusion cutting and sealing device of a horizontal bag-making filling and packaging machine incorporating a belt conveyor according to the first invention will be described.

Trajectory X1 and X2 of a flat circle in which the upper and lower heaters H1 and H2 are vertically symmetrical
To be packaged in the tube F while performing the box motion
A two-row end seal (heat seal) is applied between W and W, and the cutter K incorporated in one of the heaters H1 (upper in the figure) pushes and slides when heat-sealing the heaters H1 and H2. The gap between the two end seals is cut. The box motion of the heaters H1 and H2 employs a groove cam (front cam) and a crank, but is not limited to this.

Then, the structure of the belt conveyor which concerns on 1st invention is demonstrated.

The belt conveyor is configured such that the lower heater H2 is separated into an upstream conveyor A and a downstream conveyor B having two conveyor belts. Conveyor drive source 5
Is provided commonly to both conveyors A and B, and both conveyors A and B are driven at the same speed in the right direction in the drawing.

The upstream belt roll group 2 that constitutes the upstream conveyor A has an upstream table movable belt roll 2a provided at an upper portion thereof so that its axial position is movable in the horizontal direction, and an upstream side provided at a fixed axial position. There is a table belt roll 2e, which stretches the conveyor belt 1 horizontally to form a transport surface, and an upstream lower movable belt roll 2b that is provided at the lower part so that the axial position is movable in the horizontal direction. There is an upstream side guide belt roll 2c and an upstream side drive belt roll 2d which are provided with a fixed axial position, and the conveyor belt 1 is stretched so as not to sag.

Similarly, the downstream belt roll group 4 forming the downstream conveyor B has a fixed axial position and a downstream table movable belt roll 4a provided in the upper part so that the axial position is movable in the horizontal direction. There is a downstream table belt roll 4e provided to form a conveyor surface by stretching the conveyor belt 3 horizontally, and a downstream flexible belt for flexure removal provided at the lower portion so that the axial position is horizontally movable. Roll 4b
In each case, there is a downstream guide belt roll 4c, 4d provided with a fixed axial position, and the conveyor belt 3 is stretched so as not to sag.

The four movable belt rolls 2a, 2b, 4a, 4b all have the same diameter.

In both cases, the interval between the upstream guide belt roll 2c and the downstream guide belt roll 4c, whose axial positions are fixed, is set to a required interval so as not to interfere with the lower heater H2 that performs box motion.

The conveyor drive source 5 includes a motor 5a and a sprocket 5b.
.About.5e and endless chains 5f to 5h, the sprocket 5d is fixed coaxially with the belt roll 2d, and the sprocket 5e is fixed coaxially with the belt roll 4c.

And, the four movable belt rolls 2a, 2b, 4a, 4b,
The movable table 6 can perform a reciprocating horizontal motion equal to the horizontal component of the box motion of the upper and lower heaters H1 and H2, and the upper and lower heaters H1 and H2 can be moved by approaching and separating the upstream movable block 7 and the downstream movable block 8. The horizontal movement can be performed according to the opening and closing of the upper and lower heaters H1 and H2 without interfering with.

More specifically, there are a pair of movable tables 6 on both sides of the conveyor, and each table comprises a horizontal guide 6a and a table body 6b guided by the horizontal guides 6a. The table body 6b includes upper and lower heaters H1 and H2. It is fixed to a heater guide member (not shown) that supports the upper and lower heaters H1 and H2 so that the upper and lower heaters can be opened and closed, and the horizontal component of the box motion of the upper and lower heaters H1 and H2. It is designed to make equal horizontal movements. Further, the table body 6b on each side has a block horizontal guide portion 61, and the upstream movable block 7 and the downstream movable block 8 are slidably fitted to the block horizontal guide portion 61, The upstream table movable belt rolls 2a and the upstream deflecting movable belt rolls 2b are supported on both sides by the pair of upstream movable blocks 7 on both sides, and the pair of downstream movable blocks 8 is provided on both sides by the pair of upstream movable blocks 8. Movable belt roll 4a for the downstream table and movable belt roll 4b for removing the downstream side flexure
Are supported at both ends.

Then, both sides of the lower heater H2 and the upstream movable block 7 and the downstream movable block 8 on each side are connected by the movable block opening / closing means 9, and the upper and lower heaters H1, H2 are connected.
Both movable blocks 7 and 8 can freely approach and separate in association with the opening and closing of the. The movable block opening / closing means 9 has a pair of links 9a and 9b, one end of which is pivotally attached to the upstream movable block 7 or the downstream movable block 8, and a long hole 91 having a required length in the vertical direction. Long hole guide bodies 9c, 9d fixed to the side end of the heater block HB for engaging and guiding the other end of the link 9a or 9b with the long hole 91 and supporting the lower heater H2. When the upper and lower heaters H1 and H2 are opened, the lower heater H2 is connected to the upstream table movable belt roll 2a and the downstream table movable belt roll 2a.
When descending so as not to interfere with 4a, a pair of links 9
a and 9b are the upstream movable block 7 and the downstream movable block 8
Of the movable table roll 2a for the upstream table.
And the movable belt rolls 4a for the downstream table are close to each other so that the gap between the upstream conveyor A and the downstream conveyor B can be substantially eliminated, and the upper and lower heaters H1, H2. Prior to this, when a pair of links 9a, 9b are projected against the upstream movable block 7 and the downstream movable block 8 to separate them from each other, the lower heater is closed. H2
Before moving up, the movable belt roll 2a for the upstream table
And the movable belt roll 4a for the downstream table are separated from each other so that a gap can be secured again between the upstream conveyor A and the downstream conveyor B.

The upstream table movable belt roll 2a is located on the upstream side of the upstream movable block 7, and the upstream deflecting movable belt roll 2b is located on the upstream side of the upstream movable block 7. In addition, the upstream side deflecting movable belt roll 2b is lower than the upstream table movable belt roll 2b by a height corresponding to one roll, so that both belt rolls 2a, 2b have a pair of upstream sides on the both sides. Both ends are supported by the movable side block 7, and the upstream conveyor belt 1 is a movable belt roll 2a for the upstream table.
Of the movable belt roll 2b for removing the flexure
Between the belt contact point of the upstream table movable belt roll 2a and the upstream contact point of the deflector movable belt roll 2b. The conveyor belt portion is stretched to be horizontal, and the conveyor belt portion between the belt contact of the upstream side deflecting movable belt roll 2b and the belt contact of the upstream side guide belt roll 2c is horizontal. Therefore, even if the upstream movable block 7 moves horizontally, the upstream conveyor belt 1 does not sag.

Similarly, the movable belt roll 4a for the downstream table is located above the upstream movable block 8 on the upstream side, and the movable belt roll 4b for downstream flexure is located below the downstream movable block 8 on the downstream side. And to
The downstream side deflecting movable belt roll 4b is lower than the downstream table movable belt roll 4b by the height of one roll, so that both belt rolls 4a, 4b have a pair of upstream side movable blocks on both sides thereof. 8, both ends of which are supported by the downstream conveyor belt 3 on the outside of the downstream table movable belt roll 4a and on the downstream side of the deflecting movable belt roll 4b. 4c, each of which is wound around the outside of the table 4c, and is stretched so that the conveyor belt portion between the belt contact of the downstream table movable belt roll 4a and the belt contact of the downstream deflecting movable belt roll 4b becomes horizontal. In addition, the conveyor belt portion between the belt contact of the downstream table movable belt roll 4a and the belt contact of the upstream guide belt roll 2c is horizontal. So as are tensioned by the, therefore, the downstream movable block 8 is prevented slack is downstream conveyor belt 3 be horizontal motion.

Next, the operation will be described.

The upstream movable block 7 and the downstream movable block 8 are mounted on the movable table 6 that performs reciprocating horizontal motion equal to the horizontal component of the box motion of the upper and lower heaters H1 and H2, and the upper and lower heaters H1 and H2 are closed. When the upper and lower heaters H1 and H2 are opened, they are close to each other.Therefore, the upper and lower heaters H1 and H2 should be closed at the upstream position of the box motion. For example, the upstream table movable belt roll 2a and the downstream table movable belt roll 4a, which are close to each other on the upper side of the lower heater H2, open so as not to interfere with the lower heater H2, When moving to the downstream position of the box motion with the upper and lower heaters H1 and H2 closed, the upstream table movable belt roll 2a and the downstream table movable belt roll 2a are moved. 4a will move horizontally while maintaining close proximity to both sides of the lower heater H2. Then, when the upper and lower heaters H1 and H2 are opened at the downstream position of the box motion, the upstream table The movable belt roll 2a for the table and the movable belt roll 4a for the downstream table will be closed so as not to interfere with the lower heater H2, and subsequently, in the state of being opened by the upper and lower heaters H1 and H2, the box motion When moving to the upstream position, the upstream table movable belt roll 2a and the downstream table movable belt roll 4a move horizontally while maintaining close proximity on the upper side of the lower heater H2.

In the above case, the upstream conveyor A has the same axial distance between the upstream table movable belt roll 2a and the upstream deflector movable belt roll 2b, and the upstream table movable belt roll 2a and the upstream guide roller. Since the change in the axial distance between the belt rolls 2c and the change in the axial distance between the upstream deflecting movable belt roll 2b and the upstream guide belt roll 2c are offset, the movable table 6 and the upstream movable block No matter where 7 is, upstream conveyor belt 1
Does not slacken, and the downstream conveyor B
Is the same as the axial distance between the downstream table movable belt roll 4a and the downstream deflecting movable belt roll 4b, and the axial distance between the downstream table movable belt roll 4a and the downstream guide belt roll 4c. Change, the movable belt roll 4b for downstream flexure and the belt roll 4c for downstream guide
Since the change of the inter-axis distance is canceled out, the winding of the downstream conveyor belt 3 does not become loose no matter where the movable table 6 and the downstream movable block 8 are located. In order to match the reciprocating horizontal motion of the horizontal component of the box motion of H2, not only the lengths of the belt conveyor surface of the upstream conveyor A and the belt conveyor surface of the downstream conveyor B are changed, but further, When the heater is in the lowered position, the lengths of both belt conveyance surfaces are changed so that the gap between the upstream belt conveyance surface and the downstream belt conveyance surface is substantially eliminated. The belt does not reversely feed the product when it loses or disappears, and the falling accident of the package is eliminated when packaging short products, small products, heavy products, and the like.
