Description

Detailed Description of the Invention [Field of Industrial Application] The present invention is a method of laminating and compressing an elastic mat-like material (herein simply referred to as a mat) such as an inorganic fiber mat suitable for use as a heat insulating material. The present invention relates to a mat lamination and compression apparatus for laminating and compressing the mats, and a mat packing apparatus for laminating and compressing the mats and placing them in a packaging bag.

[Conventional technology]

Fibrous mats such as glass wool and rock wool used for insulation materials usually have a density of 8 to 24 kg/n? .

Many have a thickness of 50 to 150 mm, a width of 220 to 915 mm, and a length of 430 to 30 mm. When such mats are stacked in large numbers, for example 6 to 32, compressed and packed, they can be easily transported and stored, and the space required for this is small. A large number of products compressed and packaged to a fraction of the size are commercially available.

The conventional method for producing compressed and packaged products in this way is explained using the example of manufacturing glass wool. A spinner rotates once. A thermosetting resin binder is sprayed onto the fiberized glass using centrifugal force, and the fiber is placed on a conveyor in a cotton collecting room. After collecting it in layers, molding it in a curing furnace, heating it, and curing it into a matte shape,
After cutting the mats to a predetermined size, an operator manually stacks the mats of a predetermined size in a compression device by hand, and presses them once in the compression device to form the final state (for example, 5050- 12Q/rrr)
The material was compressed into a plastic bag, and then packed in that state by being pushed from the side into a plastic bag using a pusher. Also, long mats were folded in half and stacked.

However, these methods have the problem of requiring a large amount of labor on one worker because the mats are stacked manually. In addition, since the mat sent by a conveyor (usually has a density of 8 to 24 kg/nf) is compressed to its final state in one step, a long stroke is required for compression, and the compression equipment becomes extremely large. Therefore, in order to solve these problems, the mats are discharged from the conveyor to the stacking position and stacked automatically.

Once this amount of mats have been stacked, they are moved to the press position and pre-compressed.Then, the newly stacked mats are fed under the pre-compressed mats at the press position, and the entire mat is then compressed. A device has been proposed in which the material is compressed to a final state and then pushed out into a packaging bag using a pusher (for example, Japanese Patent Publication No. 57-
(See Publication No. 48448).

[Problem to be solved by the invention]

However, although this device automatically stacks mats, the mats used at that time are simply flat mats, and it is not possible to stack mats that are folded in half and have a strong restoring force and have a density of 16 kg/rrr or more. There was a problem that I couldn't do it.

Furthermore, since the above-mentioned apparatus simply stacks the mats before pre-compression, a large compression stroke is required to pre-compress the mats. Moreover, the mat □, which has not been pre-compressed, is stacked and fed under the pre-compressed material, and the whole is compressed to the final density.

The newly supplied mat is eventually compressed in one stage from the uncompressed state to the final state, resulting in a large compression stroke. In order to compress the mat to its final density, high-pressure compression is required, which ultimately requires a compression device with high pressure and a large stroke, which not only makes the device extremely large, but also takes a long time to complete the compression stroke. There was also the problem that production efficiency decreased.

Furthermore, recently, the demands of users have become diverse, and the width and length of the required products are diverse, but there has been no mechanical device that can meet these demands. Additionally, if you try to use a compression device designed for mats with a certain thickness on mats that are thicker than that, the compression stroke may be insufficient and the compression device may not be able to handle a wide variety of mats. There was also the problem that it was difficult.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a compact laminating and compressing device that can automatically laminate and compress even mats with a large restoring force that are supplied in a folded state. With the goal.

In addition, the present invention can automatically stack and compress the mats sent from the 9 conveyors, and furthermore, it is possible to compress the mats to the final density and pack them without using a small compression stroke. The purpose is to provide a compact packaging device.

This elevating table 9 can be raised and lowered to a position for receiving the mat to be packaged (the position shown by the solid line in FIG. 5) and a position for sending the received mat to the roller conveyor 10 (the position shown by the two-dot chain line).

Next, the operation of the above-mentioned stealing packaging device will be explained.

In FIG. 2, a conveyor 1 conveys a mat 2 folded in two and supplies it to a presetter 3.
The mat 2 is pre-compressed while being laminated. The operation will be explained below with reference to FIG.

FIG. 6 (In Ml, when the first mat 2 is fed.

The mat support member 17 is pushed upward by the lifting mechanism 22, and is constantly pushed upward.

When the mat 2 is fed from the conveyor 1, the top roller 15. The middle roller 14 rotates and feeds in the direction of arrow B. When the leading edge of the mat 2 reaches a predetermined position (FIG. 6(bl)), a sensor (not shown) detects this and stops the rotation of the top roller 15.ξ dollar roller 14.

Note that the lateral position of the mat 2 is regulated by a guide member 24.

Next, as shown in FIG. 6 (C1), the ξ dollar roller 14 and the mat pressing member 16 retreat and retreat from under the mat 2. At this time, the half-folded mat 2 instantly expands due to its own elasticity. However, since the mat support member 17 is located directly below the middle roller 14, the mat 2
It is restrained by the mat support member 17 and the top roller 15, and will not open wide.

Immediately after the middle roller 14 and the mat holding member 16 retreat, the vertical pusher 28 descends and presses the mat 2, as shown in FIG.
Push down 7 as well. At this time, the lower end position of the vertical pusher 2B is slightly lower than the mat pressing member 16. Next, as shown in FIG. 6(e), the middle roller 14 and the mat pressing member 16 move forward so as to be positioned above the mat 2 pressed by the vertical pusher 28. Thereafter, the vertical pusher 28 returns to its original position above. As a result, as shown in FIG. 6(f), the previously supplied mat 2 is sandwiched between the pine I supporting member 17 and the mat pressing member 16. Here, since the pine I/supporting member 17 is pushed up with a constant pressing force even when the vertical pusher 28 is lowered and thereafter, the mat 2 is maintained in a compressed state to a certain extent, that is, in a pre-compressed state. .

After the vertical pusher 28 is raised to its original position, a new mat 2 is supplied between the middle roller 14 and the top roller 15, as shown in FIG. 6(f). After that, see Figure 6.1. By repeating the operations (C1, tdl, tel, ff), the newly fed mat is stacked on the previously fed mat, and in a pre-compressed state, the mat supporting member 17 and the mat pressing member 16 are stacked. be restrained between

By repeating the above operations, a predetermined number of sheets are stacked and pre-compressed, as shown in FIG. 6, tg+.

Thereafter, as shown in FIG.
Insert between the bottom plate 34 and top plate 33 of the.

On the other hand, after the mat 2 is pushed out and the push plate 37 of the first extrusion pusher 6 retreats to its original position, the mat support member 17 quickly moves near the mat holding member 16, as shown in FIG. 6 (1). and waits for the ninth mat supply. Thereafter, the presetter 3 repeats the same operation.

The moving press 4 that has received the pre-compressed mat 2 moves in the direction of arrow A from the solid line position in FIG. 33, the mat 2 is compressed to a predetermined density. Then, the moving press 4 stops at the position where one mat 2 is aligned with the packaging tube 47, and the second extrusion pusher 7 is activated to extrude the mat 2 into the packaging bag 48 placed over the packaging tube 47 to produce one bag. Close the opening to complete packaging. The packed mat is then delivered onto a roller container 10. After performing this operation for each of the three rows of mats, the moving brace 4 moves back to the original pre-center 3 and waits.

As described above, the mats 2 supplied one after another from the conveyor 1 are stacked and pre-compressed by the presetter 3, then compressed to the final density by the moving press 4, and then placed in a packaging bag and packed. and roller conveyor 1
sent out on 0.

In the above process, the degree of preliminary compression in the presetter 3 is not particularly limited; for example, if the density is 10
~24 kg/n? (7)? −/ ) as the final d,
When compressing to 50 to 120 kg/rd, the presetter 3 preferably precompresses to 30 to 50 kg/n.

In the above embodiment, three rows of mats compressed by the moving press 4 were extruded one by one and packed.

Alternatively, three rows of mats may be extruded and packed at the same time. In addition, although the packaging bag opening frame 8 is provided separately from the moving brace 4, the moving brace 4
A packaging tube for putting the mat into a packaging bag may be provided.

Next, the results of actual packaging using the packaging apparatus shown in the drawings will be shown as Example 1.

Example 1 The device shown in the drawing has a thickness of 100 m, a width of 3001 m, a length of 24501 m, and a density of 16 kg/n? The mat was folded in half and supplied to the Bri center 3 by the conveyor 1.

In presetter 3, 16 sheets were laminated while being pre-compressed to a density of 48 +r/n. The total thickness when 16 sheets were laminated was about 107 cm.

Next, push out the 16 mats pre-compressed at the pre-center 3 into the moving breath 4,
It was compressed to a density of 1) 4 kg/-. The thickness at this time was about 45 cm, and therefore the amount of movement (compression stroke) of the bottom plate 34 was about 62 values.

The mat compressed by the presetter 3 is transferred to the second extrusion pusher 7
It was extruded through the packaging cylinder 47 and placed in a plastic packaging bag attached to the packaging cylinder 47, and the opening of each bag was heat-sealed. As a result, it was possible to obtain a well-wrapped mat package.

〔Effect of the invention〕

As explained above, one of the laminated compression apparatuses of the present invention is as follows.

The mat sent from the conveyor is received between the top roller row and the middle roller row. Next, the middle roller row and the mat holding member below are evacuated, and then the mat is pushed downward with a vertical pusher. The mat support member and the mat support member are pressed against the mat support member located below or onto the mats accumulated on the mat support member, and then the mat support member and the middle roller row are returned thereon. Since the structure is such that the mats are kept in a compressed state, it is possible to stack the supplied mats while compressing them. Can be stacked while being restrained. Thus,
This has the effect that the mats can be laminated and compressed automatically.

Also, at this time, the mats are stacked while being compressed, so
There is no need for a compression stroke that is required in the conventional case where the mats are laminated and then compressed, and therefore the apparatus can be made smaller.For example, when stacking 16 mats shown in Example 1 above, the conventional When stacked and compressed as shown, the thickness at the time of stacking is 200m x 16 sheets = 320cm
So, to compress this to 107cm.

Although a compression stroke of 213 cm is required, the present invention has the advantage that this compression stroke can be omitted and the device can be made smaller.

Next, the packing apparatus of the present invention uses the above-mentioned laminated compression apparatus as a preliminary compression apparatus, that is, a presetter, and has a compression apparatus behind it that compresses the mat to the final density, so that the mat is compressed in two stages. Therefore, the compression stroke of the downstream compression device can be shortened.

As mentioned above, the stacking compression device used in the first stage stacks the sheets without compressing them, so there is no need for a compression stroke after stacking, and since the first stage is compressed here, the pressure required for compression is low. 5 As a result, the device is slim and compact, and manufacturing costs are low. In addition, high-pressure compression is required in the subsequent compression device that compresses to the final density, but this compression stroke can be made smaller, making the device more compact and the weight of the machine lighter. It is easier and the production cost is lower.

Furthermore, since the previous-stage lamination and compression device laminates the mats while compressing them, it can be used for mats of different thicknesses, and can easily accommodate changes in conditions such as changing the thickness of the mat. In the I+1 device as well, since the compressed mat is further compressed, the effect of changing the thickness of the mat is small, and therefore it can easily respond to changes in conditions such as changing the thickness of the mat.

Furthermore, as shown in the first illustrated embodiment, for the conveyor 1 that conveys the plurality of rows of mats 2, there is provided a center 3 having a width that allows the plurality of rows of mats 2 to be received and stacked as they are;
If the moving brace 4 is wide enough to accept multiple rows of mats pre-compressed by the pre-compression center 3, the mats can be stacked and compressed in parallel for each supply row, resulting in extremely high productivity.

It is possible to keep up with the production speed without using multiple packaging machines in parallel as in the past, and it can be used by directly connecting to the mat production line. Furthermore, the guide member 24 disposed on the presetter 3. By making the horizontal mounting position of the vertical pusher 28 adjustable, it is possible to easily accommodate changes in conditions such as changes in the width of the mat. For this reason.

The packaging apparatus of the illustrated embodiment can easily be used for a wide variety of products.
