Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminating and compressing device for a mat for laminating and compressing an elastic mat-like material (herein referred to simply as mat) such as an inorganic fiber mat suitable for use as a heat insulating material. .

[0002]

2. Description of the Related Art A fibrous mat such as glass wool and rock wool used as a heat insulating material usually has a density of 8 to 24.
kg / m ³ , thickness 50-150 mm, width 220-9
Most of them have a length of 15 mm and a length of 430 to 3000 mm. Such a mat has a merit that when a large number of mats, for example, 6 to 32, are stacked, compressed, and packed, they are easy to transport and store, and the space required for that is small, so that the thickness at the time of use is great. There are a large number of products on the market that are compressed and packed to a fraction of the length.

The conventional method for producing such a compressed and packed product will be explained by taking the production of glass wool as an example. A thermosetting resin binder is sprayed on the glass fiberized by the centrifugal force of a rotating spinner to collect the cotton wool in the cotton collecting chamber. Collected in layers on the conveyor, molded in a curing furnace, heated and cured to form a mat, cut into a predetermined size, and then the operator manually puts a mat of a predetermined size sent out on the conveyor. It is sequentially stacked in the compression device, and the final state (for example, 50 to 100 kg /
It was compressed to about ³ m3), and in that state, it was packed by pushing it into the plastic bag from the side with a pusher. Also, long mats were folded in two and stacked.

However, these methods have a problem that a large amount of labor is imposed on the operator because the lamination of the mat is a manual operation.

In order to solve these problems, the mat is discharged from the conveyor to the stacking position and automatically stacked, and when a certain amount of the mat is stacked, it is moved to the press position to be ready. Compress and then feed the newly laminated mat in the stacking position under the pre-compressed mat in the pressing position to compress it to the final state by compressing the whole and then into the packaging bag with a pusher A device configured to push out has been proposed (see, for example, Japanese Patent Publication No. 57-48448).

[0006]

However, in this device, the mats are automatically laminated, but the mats at that time are merely flat and have a strong restoring force when folded in two, for example, when the density is high. There is a problem that mats of 16 kg / m ³ or more cannot be laminated.

Further, in the above apparatus, before performing precompression,
Since the mat is simply laminated, it requires a large compression stroke to pre-compress it. Moreover, since the mat that has not been pre-compressed is stacked under the pre-compressed product and sent, and the whole is compressed to the final density, the newly supplied mat is eventually one stage from the uncompressed state to the final state. Since it has been compressed with, a large compression stroke is eventually required. In order to compress the mat to the final density, high-pressure compression is required, so a high-pressure and large-stroke compressor is required, which not only makes the device extremely large, but also requires a long compression stroke. There was also a problem that the production efficiency was reduced.

The present invention has been made in view of the above problems, and automatically stacks and compresses a mat supplied in a flat state or a mat supplied in a folded state with a large restoring force. It is an object of the present invention to provide a compact laminated compression apparatus that can be used.

It is connected to the device 28b.

As can be seen from FIGS. 2 and 3, a flat top plate 29 is provided below the mat pressing member 16 so as to be located between the upper guide 24e and the auxiliary guide 24g. The top plate 29 is for pressing the upper surface of the mat laminated below it, and has a shape divided from the center in the left-right direction with respect to the mat moving direction, but is continuous in the mat moving direction. . Further, this top plate 29 is indicated by an arrow C-C in FIG.
It is provided so as to be movable in the direction, and is connected to a top plate driving device (not shown) that horizontally reciprocates the top plate 29 in and out of the mat stacking position.

In FIG. 6, the packing bag mouth frame 8 is provided with a packaging cylinder 47 of a size that allows the mat 2 to pass therethrough at a position corresponding to the mat 2 compressed in the moving press 4. As shown by the chain double-dashed line, by covering the packaging bag 48 and pushing out the mat 2, the mat can be packaged in the packaging bag. The roller conveyer 9 sends out the packed mat.

Next, the operation of the packing apparatus having the above structure will be described. In FIG. 1, the conveyor 1 conveys the mat 2 and supplies it to the presetter 3, and the presetter 3 is the mat 2
Pre-compress while laminating. The operation will be described below with reference to FIGS. 7, 8 and 9. 7 to 9, (A), (B), and (C) are schematic cross-sectional views of the presetter viewed from the lateral direction with respect to the mat moving direction, (a),
(B), (c) is the schematic sectional drawing which looked at the presetter in the mat movement direction. Further, in order to simplify the drawing, it is illustrated that a wide mat is laminated instead of three rows of mats.

FIGS. 7A and 7A show a state immediately after the predetermined number of mats 2 are stacked between the top plate 29 and the bottom plate 30 and compressed by the previous stacking operation. . At this time, the mat support elevating member 17 is retracted to the side of the mat stacking position. When the next mat 2 is fed from the conveyor 1 between the top plate 15 and the bottom roller 14 in this state, the top roller 15 and the bottom roller 14 rotate and are fed in the direction of arrow B. When the tip of the mat 2 reaches a predetermined position, a sensor (not shown)
Detects it, and the top roller 15 and the bottom roller 14
To stop the rotation of. At this time, since the mat 2 is sandwiched between the upper and lower rollers 14 and 15, the mat 2 does not spread even when the folded mat is fed. The lateral position of the mat 2 is restricted by the guide member 24 (see FIG. 3 and the like).

Next, as shown in FIGS. 7B and 7B,
The bottom roller 14 and the mat pressing member 16 retract and retract from the bottom of the mat 2, and the mat is dropped downward and placed on the top plate 29. At this time, when a mat folded in two is supplied as the mat 2, the mat tries to spread due to its elasticity, but the top plate 29
Is located immediately below the bottom roller 14, the mat 2 is not constrained by the top plate 29 and the top roller 15 of the mat 2 and is prevented from wide opening to cause a trouble.

Immediately after the bottom roller 14 and the mat pressing member 16 retract, the vertical pusher 28 descends and presses the mat 2 so that the upper surface of the mat 2 becomes lower than the mat pressing member 16. On the other hand, in parallel with these operations, immediately after the predetermined number of mats are stacked between the top plate 29 and the bottom plate 30, the first extrusion pusher 6 starts to move forward, and the mats that are stacked and compressed. The laminated body of is extruded to the moving press 4.

After the vertical pusher 28 pushes down the mat 2, the bottom roller 14 and the mat pressing member 16 are advanced so as to be located above the mat 2 being pressed by the vertical pusher 28. After that, the vertical pusher 28 returns to its original position above. As a result, FIG.
As shown in (C) and (c), the mat 2 is sandwiched between the top plate 29 and the mat pressing member 16. In this state, the next mat 2 is fed between the bottom roller 14 and the top roller 15. Further, in parallel with this operation, the mat support elevating member 17 moves to the mat stacking position below the top plate 29.

Next, as shown in FIGS. 8A and 8A,
The top plate 29 retreats, and the mat 2 on the top plate 29 is transferred onto the mat support lifting member 17.
Next, the bottom roller 14 and the mat pressing member 16 retract, the mat 2 on the bottom roller 14 is overlaid on the mat 2 supported on the mat supporting elevating member 17, and then the vertical pusher 28 descends again. , The upper surface of the uppermost mat 2 is pressed to a position lower than the mat pressing member 16. At this time, the mat support elevating / lowering member 17 is slightly lowered. Here, the lowering of the mat support elevating / lowering member 17 may be carried out by a drive device (not shown) for elevating / lowering the mat support elevating / lowering member 17 so that the mat support elevating / lowering member 17 is positively lowered by a predetermined amount. An upward force may be applied to the support elevating / lowering member 17 so that when the vertical pusher 28 pushes down on the mat, the vertical pusher 28 pushes down the mat by an appropriate length.

After the mat 2 is pushed down by the vertical pusher 28, the bottom roller 14 and the mat pressing member 16 are again pressed.
Moves to the mat stacking position, and the mat support lifting member 17
The upper surface of the mat 2 laminated thereon is pressed, and then the vertical pusher 28 is raised to its original position. After that, the next mat 2 is fed between the bottom roller 14 and the top roller 15 and stacked on the mat on the mat support elevating / lowering member 17 by the same operation as described above. In this manner, as shown in FIGS. 8B and 8B, the mat support elevating / lowering member 17 is gradually lowered, and a large number of mats 2 are placed thereon.
Are stacked. At this time, the mat support lifting member 17
The amount of descent may be approximately equal to the thickness of the mat to be laminated, or may be less than that.
If the descending amount of the mat support elevating / lowering member 17 is set to be smaller than the thickness of the mat to be laminated, the difference corresponding to the difference is
The mat will be laminated while being compressed.

As the mats are stacked, the mat support elevating / lowering member 17 is lowered, and when a predetermined number of mats are stacked, the mat support elevating member 17 reaches the vicinity of the bottom plate 30. At this time, the number of mats stacked on the mat supporting elevating member 17 is counted by a counter (not shown), and a predetermined number of mats are accumulated on the mat supporting elevating member 17 from the count value. It is detected that the mat support elevating member 17 has reached near the bottom plate 30. Next, FIG.
As shown in (C) and (c), the mat support lifting member 17
Moves to the outside of the mat stacking position, and the stacked mat 2 is placed on the bottom plate 30. On the other hand, the mat support elevating / lowering member 17 retracted laterally rises to a position just below the top plate 29 and stands by.

Thereafter, the mat stacking operation is continued in the same manner as above. That is, the mat 2 is fed between the bottom roller 14 and the top roller 15, the bottom roller 14 and the mat pressing member 16 retract laterally, and the vertical pusher 28 pushes down the mat 2 and is laminated below it. The operation of compressing the mat, and then returning the bottom roller 14 and the mat pressing member 16 to their original positions to press the upper surface of the mat on which the mat pressing member 16 is laminated and raise the vertical pusher 28 to its original position. Is repeated. This allows the bottom plate 3
A large number of mats are laminated on the 0 while being compressed. Here, as described above, the new mat is restrained by the bottom roller 14 and the top plate 15 and is laminated while being compressed by the vertical pusher 28, so that the mat folded in two can be well laminated without causing any trouble. And it is compressed. Further, since the mats are compressed each time they are stacked, the compression stroke may be smaller than in the case where a large number of mats are stacked without being compressed as in the conventional case and then the entire mat is compressed. Therefore, the stroke of the vertical pusher 28 is reduced. Can be made relatively small.

When a predetermined number of mats to be packed are stacked on the bottom plate 30, the vertical pushers 28 are lowered and stacked as shown in FIGS. The mat 2 is further compressed so that the uppermost surface is lower than the mat supporting elevating member 17. Next, as shown in FIGS. 9B and 9B, the mat support elevating / lowering member 17 moves to the mat stacking position, and then the vertical pusher 28 rises to the original position. As a result, the upper surface of the laminated mat 2 is pressed by the mat support elevating / lowering member 17. Thereafter, as shown in FIGS. 9C and 9C, the top plate 29 moves to the mat stacking position, and the mat support elevating member 17 retracts to the outside of the mat stacking position. As a result, as shown in FIGS. 7A and 7A, a large number of mats 2 are stacked between the top plate 29 and the bottom plate 30, and are in a compressed state.

With the above, one mat lamination compression operation is completed. By repeating the same operation thereafter, a large number of mats are stacked between the top plate 29 and the bottom plate 30 and compressed. The mat 2 between the top plate 29 and the bottom plate 30 is shown in FIG.
As shown in (b), it is extruded by the first extrusion pusher 6 and inserted between the bottom plate 34 and the top plate 33 of the moving press 4 shown in FIG. Where the top plate 29
Since the bottom plate 30 is continuous in the mat movement direction, the compressed mat can be pushed out without any trouble. If the top plate 29 and the bottom plate 30 have a shape having a large gap in the mat movement direction like the mat pressing member 16 and the mat supporting elevating member 17, the surface of the mat is caught in the gap and rubbed,
The surface may be damaged or, in extreme cases, the mat may pop out from the gap, causing troubles, but this is not the case in the present invention.

The moving press 4 receives the mat 2 which has been compressed (pre-compressed) to some extent by the presetter 3.
Moves from the solid line position in FIG. 5 in the direction of arrow A, and as shown in FIG. 6, the bottom plate 34 is lifted by the lifting mechanism 35, and the mats 2 reach a predetermined density with the top plate 33, as shown in FIG. Compress. Then, the moving press 4 is stopped at the position where one mat 2 is aligned with the packaging cylinder 47, and the second extrusion pusher 7 is actuated to push the mat 2 into the packaging bag 48 covered with the packaging cylinder 47. Close the mouth to complete the packaging. The packed mat is then transferred to the roller conveyor 9
Sent to the top. After performing this operation for each of the three rows of mats, the moving press 4 returns to the back of the original presetter 3 and stands by.

As described above, the mats 2 successively supplied from the conveyor 1 are laminated by the presetter 3 and pre-compressed, then compressed by the moving press 4 to the final density, and then put in the packaging bag. They are packed, packed, and delivered onto the roller conveyor 9.

In the above process, the degree of pre-compression with the presetter ³ is not particularly limited, but for example, a mat having a density of 10 to 24 kg / m ³ is finally obtained.
In the case of compressing to 50 to 100 kg / m ³ , the presetter ³ preferably pre-compresses to about ³⁰ to 50 kg / m ³ .

In the above embodiment, the three rows of mats compressed by the moving press 4 are extruded and packed one by one, but instead, three rows of mats may be extruded and packed at the same time. Although the packing bag mouth frame 8 is provided separately from the moving press 4, the moving press 4 may be provided with a packaging cylinder for putting the mat in the packaging bag.

[0041]

As described above, according to the laminated compression apparatus of the present invention, the mat sent from the conveyor is
The mat on the bottom roller row is dropped by receiving it between the top roller row and the bottom roller row, and then retracting the bottom roller row and the mat pressing member underneath it sideways. It is laminated on the member, then the uppermost mat is pressed downward by the vertical pusher, then the mat pressing member and the bottom roller row are returned on top of it, and the mat support lifting member is lowered as the mat is stacked. By repeating the operation, it is possible to stack the mats one after another without releasing the mats. Therefore, even if the mat is folded in two and has a large restoring force, it can be stacked while being held in the folded state. You can

When the mat support elevating member descends to the vicinity of the bottom plate disposed below, the mat supporting elevating member is retracted laterally so that the laminated mat is placed on the bottom plate, and then further. By continuing the mat stacking, the mat can be stacked on the bottom plate while being compressed, and the stroke required for the compression becomes smaller than that in the case where the entire mat is simply compressed after the predetermined number of mats are stacked, and the device can be downsized.

Further, after a predetermined amount of mat is laminated on the bottom plate, the upper surface of the mat is pressed by a vertical pusher, and then the mat supporting elevating member is raised and moved onto the mat to hold the mat upper surface. After retracting the vertical pusher upwards, position the top plate above the mat support elevating member, and then retract the mat support elevating member sideways, so that the upper and lower surfaces of the stacked and compressed mats are top and bottom. It can be sandwiched between plates, and since the top plate and bottom plate have a continuous surface, the stacked and compressed mat can be extruded by the extrusion pusher without any trouble, and the next device (for example, moving press) Can be supplied to.

As described above, the apparatus of the present invention can compress the mats sent out from the conveyor while successively stacking them, stacking and compressing a predetermined number of mats, and then sending them out to the next step,
Moreover, there is an effect that the device can be made relatively small.
