When the rods 113 of the pair of peeling bodies 111 enter between the joint surfaces of the side surfaces of the spring unit 96 and the outer casing 97, the outer casing 97 covers the one surface of the spring unit 96 and the other surface. 13 is bent in the direction indicated by the arrow Y in FIG. 13 and is fed between the pair of rotating bodies 5 and 7 of the first separating means 6 and the second separating means 8.

The exterior body 9 fed between the pair of rotating bodies 5 and 7 of the first separating means 6 and the second separating means 8, respectively.
7 is guided by a pair of discharge guide members 115 each having a substantially L-shaped cross section and discharged in a direction substantially perpendicular to the transfer direction of the spring unit 96 shown by an arrow Z in FIG. There is.

As shown in FIG. 5, one end of the discharge guide member 115 has a recess 115a for preventing the shaft-like member 13 provided on the cylindrical body 11 of the rotating bodies 5, 7 from interfering with each other. Are formed.

Next, the spring unit 96 of the mattress 91 and the exterior body 97 are processed by the disassembly processing apparatus having the above-mentioned configuration.
A procedure for separating and will be described.

First, before sending the mattress 91 to the disassembly processing device, as shown in FIG. 14, a cut 91a is formed on the front end surface of the mattress 91 in the feeding direction. And
The portion of the outer casing 97 that covers the above-mentioned tip surface is pushed leftward and rightward as shown by the arrow in the figure to expose one end of the spring unit 96.

Further, before sending the mattress 91 to the disassembly processing device, the distance between the first separating means 6 and the second separating means 8 is adjusted according to the thickness dimension of the mattress 91. That is, the distance between the pair of guide members 101 is set to the mattress 91.
The thickness of the mattress 91 is adjusted to be approximately the same as the thickness of the spring unit 96 of the mattress 91.

The above-mentioned first separating means 6 and second separating means 8
The interval adjustment mechanism 61 adjusts the interval between and. That is, the third drive source 62 of the interval adjusting mechanism 61 is operated,
The upper drive screw shaft 75 and the lower drive screw shaft 85 are rotated to drive the upper mounting plate 34 and the lower mounting plate 33. Thereby, the guide member 101 and the peeling body 111 on the side of the second separating means 8 attached to the attaching plates 34 and 33 are attached.
, The distance between the pair of guide members 101 can be set to be substantially the same as the thickness dimension of the mattress 91, and the distance between the pair of peeling bodies 111 can be set to be substantially the same as the thickness of the spring unit 96.

Guide member 1 by the third drive source 62
01 and the peeling body 111 are adjusted, since the pointer 114 provided on the guide member 101 of the second separating means 8 moves along the scale 113 provided on the top plate 4, the pointer 114 is attached to the scale 113. It suffices to move the mattress 91 to a position indicating a scale substantially the same as the thickness dimension thereof.

That is, the width dimension of the space 110 between the pair of separating means 6 and 8 is set by the pointer 114 and the scale 1 described above.
It is possible to easily carry out the processing by using 13.

Furthermore, the height position of the upper cutter 105 is
It is adjusted according to the width dimension of the mattress 91 (height dimension during transportation). That is, when the mattress 91 is fed into the space 110 in a standing position, the portion of the exterior body 97 that covers the upper end surface and the lower end surface of the mattress 91 is cut by the upper cutter 105 and the lower cutter 106. Set.

When the adjustment of the respective parts is completed in this way, the first drive source 25 is operated to rotationally drive the pair of rotating bodies 5 of the first separating means 6 in the direction shown by the arrow in FIG. Also, the second drive source 51 is operated to rotationally drive the pair of rotating bodies 7 of the second separating means 8 in the direction shown by the arrow in FIG.

Then, the mattress 91 is fed into the space 110 between the first separating means 6 and the second separating means 8. That is, in a state where the tip end surface of the mattress 91 in which the cut 91a is formed faces the space portion 110 side and the lower end surface is placed on the carry-in roller 92 arranged at one end side of the main body 1,
The mattress 91 is moved onto the first delivery roller 103a provided on the bottom plate 2.

The mattress 91 has a pair of exfoliation bodies 1 with the front end surfaces thereof.
11 when they come into contact with the rod 113,
Enters between the joint surfaces of the spring unit 96 and the exterior body 97. As a result, the portion of the exterior body 97 that covers one side surface side of the spring unit 96 and the portion that covers the other side surface side thereof are respectively bent in directions away from the one side surface and the other side surface of the spring unit 96.

Exterior body 9 bent by peeling body 111
7, one part of which is sandwiched between the pair of rotating bodies 5 of the first separating means 6 and is forcibly sent out from the discharge guide member 115, and the other part of which is the pair of rotating bodies of the second separating means 8. It is sandwiched by 7 and is forcibly sent out from the discharge guide member 115.

Since the shaft-shaped member 13 and the circular hole 14 are formed at corresponding positions on the peripheral walls of the pair of rotating bodies 5 and 7, the outer casing fed between the pair of rotating bodies 5 and 7 is provided. Body 97
The one portion and the other portion are pressed by the shaft-shaped member 13, and the pressed portion enters the circular hole 14.

Therefore, since each part of the exterior body 97 is firmly sandwiched by the pair of rotating bodies 5 and 7 and fed, the exterior body 97 is fed with the pre-formed cut 91a and the mattress 91. A pair of cutters 10
2 along the cut 91b formed by 6,107
It will be sent out from each of the rotating bodies 5 and 7 while being cut into two parts.

That is, even if the outer casing 97 is firmly clipped to the spring unit 96, it is reliably separated from the spring unit 96 by the rotational force of each pair of rotating bodies 5 and 7.

Then, when one part and the other part of the outer casing 97 are sent out in the direction of arrow Z by the pair of rotating bodies 5 and 7 of the separating means 6 and 8, the spring unit 96 together with the outer casing 97 is formed. It is sent in the direction indicated by arrow X in FIG.

As a result, the spring unit 96 moves on the second transfer roller 103b and the carry-out roller 94 and is carried out from the space 110.
The mattress 91 has a spring unit 96 and an exterior body 97.
Can be separated into

Spring unit 96 of mattress 91
The outer casing 97 and the outer casing 97 are respectively sent out in a predetermined direction from the pair of separating means 6 and 8. Therefore, since the mattress 91 to be disassembled can be continuously fed into the space 110 of the pair of separating means 6 and 8, the disassembling work can be performed efficiently.

The mattress 91 may have different thickness and width dimensions. When the thickness dimension of the mattress 91 is different, the second separating means 8 is driven toward and away from the first separating means 6 in accordance with the thickness dimension, and the pair of guide members 101 and each pair of guide members 101 are moved. Rotating bodies 5, 7 and a pair of peeling bodies 1
Adjust the 11 spacing.

As a result, the mattress 91 is attached to the space 1
When it is sent to 10, the rod 113 of the peeling body 111 is surely inserted between the pair of side surfaces of the spring unit 96 and the joint surface between the outer body 97, and one portion and the other portion of the outer body 97 are connected. The first separating means 6 and the second separating means, respectively.
It is possible to send to the separating means 8 of.

The exterior body 9 depending on the type of the mattress 96
7 may have different thickness dimensions. The exterior body 97 is sandwiched between the pair of rotating bodies 5 and 7 of the separating means 6 and 8 and sent out. Therefore, when the outer casing 97 becomes thin, the outer casing 97 cannot be firmly clamped by the rotating bodies 5 and 7 unless the space between the pair of rotating bodies 5 and 7 is narrowed, and conversely, the outer casing 97 becomes thicker. In some cases, it will not be possible to send it out smoothly unless it is widened.

The rotating bodies 5 and 7 on one side of each of the separating means 6 and 8 are rotatably supported by the movable portion 19 of the take-up bearing 17 at the support shafts 12 at the upper and lower ends. The movable portion 19 is elastically slidable by a spring 23.

Therefore, when the thickness of the outer casing 97 fed between the pair of rotating bodies 5, 7 of each separating means 6, 8 is small, one of the rotating bodies 5, 7 is rotated by the restoring force of the spring 23. When it is thick, it slides in the direction of approaching the body, and when it is thick, it slides in the direction of separating against the urging force of the spring 23.

Therefore, even if the thickness of the outer casing 97 is changed, the separating means 6 and 8 have a pair of rotating bodies 5 and 7, respectively.
Thus, the outer casing 97 can be reliably held and smoothly delivered.

Gears 15, 29 and 44, 46 meshing with each other for transmitting the power of the first and second drive sources 25, 51 to the spindle 12 at the upper end of each pair of rotating bodies 5, 7. Is provided. Therefore, the distance between the pair of rotating bodies 5 and 7 can be adjusted within a range in which the meshing state of the gears 15, 29 and 44, 46 is not impaired.

A bottom plate 2 of the main body 1 is provided with a carry-in roller 92 at one end of the main body 1 and a carry-out roller 94 at the other end.
A first delivery roller 103a and a second delivery roller 103b are provided above.

For this reason, the mattress 91 sent into the space 110 has the rollers 92, 94, 103a, 1
By rolling on 03b, it is smoothly transferred to the discharge side, so that the outer casing 97 can be smoothly peeled off.

In other words, in the mattress 91 carried into the space 110, one pair of the outer casing 97 and the other pair of the rotating members of the first separating means 6 and the second separating means 8, respectively. The mattress 9 is moved by being sandwiched and carried by the parts 5 and 7. Therefore, the mattress 91 is attached to each roller 9
The smooth movement by 2, 94, 103a, and 103b allows the exterior body 97 to be smoothly separated and discharged.

Next, another embodiment of the present invention will be described. The same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

FIG. 15 shows a second embodiment of the present invention showing a modification of the first separating means 6 and the second separating means 8. In this embodiment, the configuration of each pair of rotating bodies 5A and 7A of each separating means 6 and 8 is different.

However, it should be sandwiched by the ridge members 161 along the axial direction of the rotating bodies 5 and 7. Thus, it is possible to prevent the exterior body 97 from being entangled with the rotating bodies 5 and 7 and reliably failing to be delivered.

FIG. 26A shows a normal mattress 91, and FIG. 26B shows the mattress 91 in a state of being fed to the peeling body 111. As shown in FIG. 26A, the mattress 91 includes a spring unit 96 and an exterior body 97 that covers the spring unit 96. Exterior body 9
Reference numeral 7 denotes a pair of upper and lower mirror grounds 165 that cover the upper surface and the lower surface of the spring unit 96, and a town 167 that covers the outer peripheral surface of the spring unit 96 and stitches the upper and lower ends to the peripheral portions of the pair of mirror grounds 165 with tape 166. It consists of and. The upper and lower surfaces of the spring unit 96 and the mirror ground 165
Cushioning material 169 such as urethane foam is laminated between and via a protective material 168 such as sisal.

The mirror ground 165 is fixed to the spring unit 96 by the flange cloth 170.

The mattress 91 having the above structure is attached to the peeling body 111.
The mattress 91, which is to be fed into the peeling body 111, is a front side surface of the mattress 91 before it is fed into the town ground 16

69 and the end of the mirror ground 165 are respectively rolled up, the upper first portion 167a and the lower second portion 167b of the cut town 167 are respectively bonded to the protective material 168, and these are bonded. The body is integrally fixed by the resin pin 171.

In this state, the mattress 91 is removed from the peeling body 111.
If the peeling body 111 is sent to the spring unit 96,
Since it surely enters between the upper and lower surfaces of the protective material 168,
The protective material 168, the cushion material 169, and the exterior body 97 can be reliably separated from the spring unit 96.

The present invention is not limited to the above-mentioned embodiments, but can be variously modified without departing from the gist of the invention. For example, in the main body, the rotating bodies of the separating means are installed so that the axes are vertical, but the rotating bodies may be installed with the axes horizontal. Further, while the mattress is arranged so that the width direction is vertically arranged to remove the exterior body, the mattress may be carried into the main body with the longitudinal direction being arranged vertically to remove the exterior body.

Further, in the first embodiment, the guide member, the separating means and the peeling means are provided in pairs, but in the case of the mattress in which only the upper surface side of the spring unit is covered with the exterior body, Only one guide member, one separating means and one peeling means may be provided so as to be located on one side surface side of the mattress.

Further, as the mattress transfer means, the carry-in roller, the delivery roller and the carry-out roller may be rotationally driven, and the mattress may be guided by a plate-shaped guide member instead of the rollers. However, the essential point is that the mattress can be transported along a predetermined direction.

[0156]

As described above, according to the present invention, the portion of the exterior body covering the spring unit is separated from the spring unit, and the exterior body is forcibly sent out in the predetermined direction.

Therefore, even if the exterior body is firmly connected to the spring unit, the exterior body can be separated from the spring unit. Moreover, since the spring unit and the exterior body separated from the spring unit are respectively sent out in the predetermined directions, the separated spring unit and the exterior body can be easily processed, and further the separation work can be performed continuously. Since it can be performed, the separation work can be performed efficiently.
