Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention laminates and compresses an elastic mat-like material (herein simply referred to as mat) such as an inorganic fiber mat suitable for use as a heat insulating material. The present invention relates to a stacking and compressing device for mats and a packing device for the mats, which stacks and compresses the mats and puts them in a packaging bag.

[Conventional technology]

The fibrous mats such as glass wool and rock wool used for heat insulating materials usually have a density of 8 to 24 kg / m ³ and a thickness of 50 to
Many are 150 mm, width 220-915 mm, and length 430-3000 mm. Such a mat has a merit that when a large number of sheets, for example, 6 to 32 sheets are stacked, compressed and packed, it is easy to transport and store, and the space required for that is small, and therefore the thickness of the mat when used is large. 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 a product packed in such a manner will be explained by taking the production of glass wool as an example. When the thermosetting resin binder is sprayed on the glass fiberized by the centrifugal force of the spinning spinner, it is placed on the conveyor of the cotton collecting chamber. After thickening into a layer, molding in a curing furnace, heating and curing to form a mat,
After cutting into a predetermined size, the operator then manually stacks the mats of a predetermined size sent out by the conveyor into the compression device by hand, and the compression device once presses the mat to the final state (for example, 50 to 50). It was compressed to about 120 kg / m ³ ), and in that state, it was packed by pushing it from the side into a plastic bag with a pusher. The long mat was folded in two and stacked.

However, these methods have a problem in that a large amount of labor is imposed on the worker because the mat is laminated manually. In addition, the mat sent from the conveyor (usually having a density of 8 to 24 kg / m ³ ) is compressed to the final state at once, so a long stroke is required for compression, and the compression device becomes extremely large. There was a problem.

Therefore, as a solution to these problems, the mat is discharged from the conveyor to the stacking position and automatically stacked, and when a certain amount of mat is stacked, it is moved to the press position and pre-compressed, Then, the newly laminated mat in the stacking position is fed under the pre-compressed mat in the pressing position and compressed to the final state by compressing the whole, and then pushed out into the packaging bag by the pusher. A structured device has been proposed (for example, Japanese Patent Publication No. 57-48448).
(See the official gazette).

[Problems to be Solved by the Invention]

However, this device automatically stacks mats, but the mats at that time are simply flat, and two-folded mats with a high restoring force and a density of 16 kg / m ³ or more should be stacked. There was a problem that I could not do it.

Further, in the above device, since the mats are simply laminated before the precompression, a large compression stroke is required to precompress the mats. Moreover, since the mat which has not been pre-compressed is stacked under the pre-compressed one and sent, and the whole is compressed to the final density, the newly supplied mat is ultimately 1 to 1 from the uncompressed state to the final state.
Since it is compressed in stages, a large compression stroke is required after all. In order to compress the mat to the final density, high-pressure compression is necessary, 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.

Furthermore, recently, there have been various demands from users, and various widths and lengths of required products are required, but none of them can mechanically cope with this. In addition, if a compression device designed for a mat of a certain thickness is used for a mat thicker than that, the compression stroke may be insufficient, and eventually, a variety of mats can be supported. There was also the problem that it was difficult.

The present invention has been made in view of the above problems, and provides a compact laminating and compressing device capable of automatically laminating and compressing even a mat having a large restoring force supplied in a folded state. With the goal.

Also, the present invention is capable of automatically stacking and compressing mats sent from a conveyor, yet compact and capable of compressing and packing mats to final density while using a small compression stroke. The purpose is to provide a packing device.

When the mat is pushed down from above, it has an effect of allowing the mat support member 17 to descend accordingly. At the descent position of the support 21, the position of the support 21 when the product for one package reaches the height where it is stacked at a constant density is calculated in advance and a stopper (not shown) so that the support 21 stops at that position Is provided. Note that instead of the stopper, a detection unit that detects that the support 21 has dropped to a predetermined position may be provided, and the lifting mechanism 22 may be controlled so that the support 21 stops at that position. The lifting mechanism 22 is not limited to the air cylinder of the illustrated embodiment, but other means may be used, for example, a hydraulic cylinder, a combination of a pinion and a rack, a combination of balance weight and chain conduction. Various mechanisms can be used, such as those using.

In FIG. 2, the top roller 15, the middle roller 14, the mat pressing member 16, and the mat supporting member 17 are arranged at the same position in the vertical direction, and a vertical guide member 24 is arranged between them. . This guide member 24 is a mat 2 and a mat pressing member which are sent in as shown in FIG.
It is arranged to regulate the position of the edge of the mat to be laminated below 16, and its upper and lower ends are attached to the support 25. The support 25 is attached to a horizontal support rod 26 provided at a fixed position so that its position can be adjusted. For this reason,
By adjusting the position of the support 25, it is possible to easily adjust the position to a position corresponding to the mats 2 having various widths.

A vertical vertical pusher 28 is provided between each guide member 24.

The vertical pusher 28 has an upper end attached to a support 29, and the support 29 is attached to a horizontal support rod 31 held by an elevating plate 30 so that the position of the support 29 can be adjusted. Thus, the position of the vertical pusher 28 can be adjusted according to the width of the mat 2. A pusher driving device (not shown) for raising and lowering the lifting plate and the vertical pusher 28 is connected to the lifting plate 30. As for the vertical range of the vertical pusher 28, the lower end of the vertical pusher 28 is the second position.
As shown in the figure, it is set so that it can descend from the position retracted above the lower surface of the top roller 15 to the bottom of the mat pressing member 16.

In FIG. 2, the moving press 4 includes a top plate 33 and a bottom plate.
34 and an elevating mechanism 35 for elevating and lowering the bottom plate 34. A mat is placed on the bottom plate 34, and the elevating mechanism 35 is used for moving the bottom plate 34.

The table lifter 40 is provided for adjusting the vertical position of the push plate 37 and the push rod 38 in accordance with changes in conditions such as the number of laminated mats and the amount of compression. Note that the push plate 37 may need to be changed when the conditions are changed.
Therefore, the push plate 37 is removable from the push rod 38.

FIG. 5 is a cross-sectional view schematically showing a state in which the moving press 4 is located between the second extrusion pusher 7 and the packing bag mouth frame 8. Similarly to the first extrusion pusher 6, the second extrusion pusher 7 also has a push plate 42, a push rod 43 holding the push plate 42, a support portion 44 that horizontally supports the push rod 43, and a horizontal push rod 43. It has a drive device (not shown) that reciprocates in and out, and a table lifter 45 on which the whole is placed. As shown in FIG. 1, the second pusher pusher 7 includes a push plate 42 and a push rod.

In FIG. 5, the packaging 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 line, by covering the packaging bag 48 and pushing out the mat 2, the mat can be packaged in the packaging bag. The lifting table 9 has a large number of rollers 50 on its upper surface. The lifting table 9 can be lifted 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 chain double-dashed line).

Next, the operation of the packing device having the above configuration will be described.

In FIG. 2, the conveyor 1 conveys the mat 2 folded in two and supplies it to the presetter 3,
Pre-compresses while laminating the mat 2. The operation will be described below with reference to FIG.

In FIG. 6 (a), when the first mat 2 is supplied, the mat support member 17 is pushed upward by the elevating mechanism 22 and is constantly pushed upward. When the mat 2 is supplied from the conveyor 1, the top roller 15 and the middle roller 14 rotate and feed in the direction of arrow B. When the tip of the mat 2 reaches a predetermined position (Fig. 6 (b)), a sensor (not shown) detects it and stops the rotation of the top roller 15 and the middle roller 14. The lateral position of the mat 2 is restricted by the guide member 24.

Next, as shown in FIG. 6 (c), the middle roller 14 and the mat pressing member 16 retract and retract from the bottom of the mat 2.
At this time, the half-folded mat 2 tries to spread instantly due to its own elasticity, but since the mat support member 17 is located immediately below the middle roller 14, the mat 2 has this mat support member 17 It is constrained by the top roller 15 and does not open greatly.

Immediately after the middle roller 14 and the mat pressing member 16 retreat, as shown in FIG. 6 (d), the vertical pusher 28 descends to press down the mat 2 and also press down the mat supporting member 17. The lower end position of the vertical pusher 28 at this time is
The position 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 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 the upper position. As a result, as shown in FIG. 6 (f), the mat 2 previously supplied is sandwiched between the mat support member 17 and the mat holding member 16. Here, since the mat support member 17 is pushed up with a constant pressing force both when the vertical pusher 28 descends and thereafter, the mat 2 is kept in a compressed state, that is, in a pre-compressed state to some extent.

After the vertical pusher 28 moves up to its original position, the new mat 2 is supplied between the middle roller 14 and the top roller 15 as shown in FIG. 6 (f). After that, by repeating the operations of FIGS. 6 (b), (c), (d), (e), and (f), the newly sent mat is laminated on the previously sent mat. , It is restrained between the mat support member 17 and the mat pressing member 16 in a pre-compressed state.

By repeating the above operation, a predetermined number of mats 2 are stacked and pre-compressed as shown in FIG. 6 (g).

After that, as shown in FIG. 6B, the push plate 37 of the first extrusion pusher 6 advances to insert the mat 2 between the bottom plate 34 and the top plate 33 of the moving press 4.

Meanwhile, the mat 2 is pushed out, and the push plate of the first extrusion pusher 6 is pushed out.
After the 37 retreats to its original position, the mat support member 17 rapidly returns to the vicinity of the mat holding member 16 and waits for the next mat supply, as shown in FIG. 6 (i). Hereinafter, 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 position indicated by the solid line in FIG. 1, and in the middle thereof, as shown in FIG. The mat 2 is compressed with the plate 33 to a predetermined density. 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, and then the bag. Close the mouth to complete the packaging.
The packed mat is then sent out onto the roller conveyor 10. 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 supplied one after another from the conveyor 1 are stacked by the presetter 3 and pre-compressed, and then compressed to the final density by the moving press 4 and then put in a packaging bag and packed. Roller conveyor 10
Sent to the top.

In the above process, the degree of pre-compression in the presetter 3 is not particularly limited, but for example, if the density is 10 to
Finally the mat 24 kg / m ^3, in the case of compressing the 50~120kg / m ^3, the presetter 3, it is preferable to pre-compressed 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 one by one and packed, but instead, three rows of mats may be extruded and packed at the same time. Further, although the packaging 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.

Next, as a first embodiment, a result of actual packing using the packing device shown in the drawings is shown.

Example 1 In the apparatus of the drawings, thickness 100 mm, width 300 mm, length 2450 mm,
A mat having a density of 16 kg / m ³ was folded in two and supplied to the presetter 3 by the conveyor 1. In the presetter 3, 16 sheets were laminated while pre-compressing this to a density of 48 kg / m ³ . The total thickness when stacking 16 sheets was about 107 cm.

Next, 16 mats precompressed by the presetter 3 were extruded into the moving press 4 and compressed by the moving press 4 to a density of 114 kg / m ³ . The thickness at this time is about 45 cm, and therefore, the movement amount (compression stroke) of the bottom plate 34 is about 62.
It was cm.

The mat extruded by the presetter 3 is used as the second extrusion pusher 7
Then, it was pushed out through the packaging cylinder 47, put into a plastic packaging bag attached to the packaging cylinder 47, and the bag mouth was heat-sealed. As a result, it was possible to obtain a well-wrapped mat package.

〔The invention's effect〕

As described above, the laminated compression apparatus of the present invention receives the mat sent from the conveyor between the top roller row and the middle roller row, and then retracts the middle roller row and the mat pressing member below it. After that, push the mat downward with the vertical pusher and push it on the mat support member located below it or on the mat accumulated on the mat support member, then,
Since the mat pressing member and the middle roller row are restored on the mat, and the mat is held in a compressed state by the mat supporting member and the mat pressing member, the mats to be supplied can be laminated while being compressed. , In particular, even a mat that is folded in two and has a large restoring force can be laminated while being restrained in the folded state. Thus, there is an effect that the mat can be automatically laminated and compressed.

Also, at this time, since the mats are laminated while being compressed,
Since the compression stroke is not required as in the case of stacking and then compressing as in the conventional case, the device can be downsized. For example, in the case of stacking 16 mats shown in Example 1 above, when the mats are stacked and compressed as in the conventional case, the thickness at the time of stacking is 200 mm × 16 sheets = 320 cm, which is compressed to 107 cm. Requires a compression stroke of 213 cm, but in the present invention, this compression stroke can be omitted and the device can be downsized.

Next, in the packing apparatus of the present invention, the above-mentioned laminated compression apparatus is used as a pre-compression apparatus, that is, a presetter, and a compression apparatus for compressing the final density is arranged behind the compression apparatus, so that the mat is compressed in two steps. Therefore, the compression stroke of the subsequent compression device can be shortened.
As described above, the laminating compressor used in the former stage does not require a compression stroke after laminating because it laminates while compressing, and since the former stage compression is performed here, the pressure required for compression is low. ， Therefore, the device is slim and compact, and the manufacturing cost is low. Further, in the latter stage compression device for compressing to the final density, it is necessary to perform high pressure compression, but since this compression stroke can be made small, the device becomes compact, the machine weight becomes light, and means for moving this is also provided. It will be easier and the production cost will be lower.

Furthermore, since the mat is laminated while being compressed in the former-stage laminating / compressing device, mats with different thicknesses can be used without any problems, and it is possible to easily adapt to changing conditions such as changing the mat thickness. Also, in the latter-stage compression device, the compressed mat is further compressed, so that there is little effect of changing the thickness of the mat, and therefore it is possible to easily deal with changing conditions such as changing the thickness of the mat.

As shown in the illustrated embodiment, with respect to the conveyor 1 that conveys the mats 2 in a plurality of rows, the presetter 3 having a width that allows the mats 2 in a plurality of rows to be directly received and stacked,
By using the moving press 4 having a width that can accept a plurality of rows of mats pre-compressed by the presetter 3, the mats can be stacked and compressed in parallel for each supply row, which is extremely high in productivity. It is possible to catch up with the production speed without using multiple packing machines in parallel, and can be used by directly connecting to the mat production line. Moreover, the guide member 24 arranged on the presetter 3,
If the horizontal mounting position of the vertical pusher 28 is adjustable, it is possible to easily deal with condition changes such as width change of the mat. Therefore, the packing apparatus of the illustrated embodiment can easily deal with various products.
