る。As shown in FIG. 9, the conventional membrane 1 has a flat plate shape having hooks on the periphery, and as described above,
It is deformed as shown in Fig. 10 and is usually stretched by 60 to 70%, and rubber with good elongation of 300 to 700% is used. Then, at the time of deliquoring, as shown in FIG.
The liquid is drained while being deformed along the object 16 to be squeezed.

ン１は矢印19方向へ伸びるとともに、矢印20方向へ移動
するため伸びの少ない洗たく物は破れる虞れがある。By the way, when the object 12 to be squeezed is squeezed by the method as described above, its volume is reduced and the height is reduced to half or less. However, since the pressing direction is from above, the diameter of the object to be squeezed 12 is conversely large, for example, the diameter of 950 mm,
After squeezing, the diameter will be 1000 mm to 1050 mm. At this time, as shown in FIG.
The outer peripheral portion of the object to be squeezed 16 is pressed against the conveyor belt 5 by the membrane 1, and the outer peripheral portion of the object to be squeezed 16 is locked and its volume is reduced. For this reason,
If compression is continued while the outer peripheral portion is locked, the membrane 1 expands in the direction of arrow 19 and moves in the direction of arrow 20, and thus the wash item having a small amount of expansion may be broken.

多く発生することとなる。As shown in FIG. 9, there is a conventional membrane 1 in which the main body has a flat plate shape made of a highly stretchable material, and the hardness of only a small portion of the peripheral edge is increased. The ratio is about 0% to 10% of the radius. This membrane 1 is the 12th
When mounted in the state shown in the figure, the hardness of only the outermost peripheral portion 21 is high, so the membrane 1 cannot be pulled out from the stopper 2, but a triangular portion 22 is always generated in the vicinity thereof, so that inside the triangular portion 22. The outer circumference of the wash item 16 is easily locked,
When the object 16 to be squeezed is squeezed by the pressurized water 10 through the membrane 1 as shown in FIG. 11, many tears occur at the portion indicated by 23.

By changing the structure of the membrane, even if the above-mentioned sandwiching part is formed between the outermost peripheral part of the membrane and the conveyor belt, a new pulling force by the membrane does not act on the compressed object sandwiched there. And it is intended to provide an effective membrane.

物には引張力が作用せず、破れるようなことがない。(Function) The membrane of the present invention has the rubber hardness of the outer peripheral portion over the range in contact with the object to be squeezed to be higher than the rubber hardness of the central portion adjacent to the outer peripheral portion. Even when the squeezing of the object to be squeezed is started, the outer peripheral portion of the membrane is suppressed from being stretched, and the portion does not deform toward the center of the membrane even during deliquoring, and moves only in the squeezing direction. Therefore, even if a part of the object to be compressed is locked at the sandwiched portion between the peripheral edge of the membrane and the conveyor belt, no tensile force acts on the object to be compressed and it does not break.
（実施例） 以下、本発明の実施例を図面について説明する。Embodiment An embodiment of the present invention will be described below with reference to the drawings.
ここでは、第９図に示した従来のメンブレンと異なる部
分を中心に説明する。Here, the description will focus on the part different from the conventional membrane shown in FIG.
第１図が本発明の実施例の１つであるメンブレンを示す
もので、同図において、51がメンブレンで断面形状は従
来のものと同様であるが、本実施例にあっては、その外
周部の相当巾に亘って硬度を高くしている。FIG. 1 shows a membrane which is one of the embodiments of the present invention. In FIG. 1, 51 is a membrane and its cross-sectional shape is the same as that of the conventional one, but in this embodiment, the outer periphery thereof is Hardness is increased over a considerable width of the part.
これを具体的に述べると、第９図に示した従来のメンブ

１図に示す斜線部52の長さl1は中心53までの半径の15％
〜35％、好ましくは18％〜32％を占めるように、この部
分の硬度を上げるものである。More specifically, in the conventional membrane shown in FIG. 9, the hardness of only the outermost peripheral portion of the bell 3 that engages with the stopper 2 is increased. However, according to this embodiment, As shown in FIG. 2, the hardness is increased not only to the engaging portion with the stopper 2 but also to a considerable portion that wraps the object to be compressed beyond the sandwiching portion 56 formed between the membrane 51 and the conveyor belt. . To explain this more specifically, the length l 1 of the hatched portion 52 shown in FIG. 1 is 15% of the radius to the center 53.
The hardness of this portion is increased so as to occupy ˜35%, preferably 18% to 32%.
ここで、前記割合を32％特に35％以上とすると、メンブ

たく物を完全に包み込むことができず、かつ均等な圧搾
もできなくなり、実用上その使用が不可能となる。Here, when the ratio is 32%, particularly 35% or more, the stretchable portion of the membrane 51 is too small to be uniformly deformed during pressing, resulting in the state as shown in FIG. It cannot be wrapped completely and cannot be evenly squeezed, making its use practically impossible.
因みに、第９図に示す従来のメンブレン１の硬度アップ
部分21は、第１図に示すl1に相当する値が、上述したと
おり０％〜10％である。Incidentally, in the hardness-increased portion 21 of the conventional membrane 1 shown in FIG. 9, the value corresponding to l 1 shown in FIG. 1 is 0% to 10% as described above.
メンブレンの構造を本実施例の如くすると、第２図にお
いてメンブレン51の外周部分の矢印54方向の伸びが抑え

ある矢印55方向のみ変化することになる。従って、たと
え被圧搾物が56で示される挟み込み部分でロックされて
も、被圧搾物には引張力が作用せず、破れが発生しな
い。When the structure of the membrane is the same as that of this embodiment, the extension of the outer peripheral portion of the membrane 51 in the direction of arrow 54 in FIG. 2 is suppressed, and this portion is in the direction of arrow 54 during deliquoring, that is, the membrane.
It does not deform in the central direction of 51, and changes only in the direction of arrow 55, which is the direction in which the object to be compressed is squeezed. Therefore, even if the object to be squeezed is locked at the sandwiched portion indicated by 56, no tensile force acts on the object to be squeezed and no breakage occurs.
第４図は本発明の他の実施例を示し、メンブレン61の外
周部である斜線で示す部分62は硬度を高くしている点で
は前述の実施例と同じであるが、この実施例の場合は前

いる。FIG. 4 shows another embodiment of the present invention, which is the same as the above-mentioned embodiment in that the shaded portion 62 which is the outer peripheral portion of the membrane 61 has high hardness, but in the case of this embodiment Is formed so that the hatched portion is raised so that the cross section thereof, which is close to the shape of the object to be squeezed after deliquoring, has a bowl shape.
ここで、前記硬度を高めてある部分の中心に向けての長
さl2は第１図に示した長さl1と同様に設定される。Here, the length l 2 toward the center of the portion having the increased hardness is set in the same manner as the length l 1 shown in FIG.
第５図は第４図に示したメンブレン61を脱水機等に装着
した場合の作用を示す。FIG. 5 shows the operation when the membrane 61 shown in FIG. 4 is attached to a dehydrator or the like.
脱液時、メンブレン61の硬度の高い斜線部62は矢印55方
向（被圧搾物の圧搾方向）のみに移動し、たとえ符号56
で示されるロック部が形成されても、被圧搾物には引張
力が作用せず、圧縮のみの力が加えられることとなり被
圧搾物が破れるようなことがない。At the time of deliquoring, the high-hardness slanted portion 62 of the membrane 61 moves only in the direction of arrow 55 (the direction of squeezing of the object to be squeezed).
Even if the lock portion shown by is formed, a tensile force does not act on the object to be squeezed, and a force of only compression is applied, so that the object to be squeezed does not break.
また、メンブレン61の断面形状を予め第４図に示す如く
脱液される被圧搾物の形状に近くしてあるため、斜線部
62の硬度アップ部分には、第５図の矢印54方向、即ちメ
ンブレン61の半径方向の力が作用していないので特に有
効なものである。Moreover, since the cross-sectional shape of the membrane 61 is close to the shape of the object to be squeezed to be drained as shown in FIG.
The hardness increasing portion of 62 is particularly effective because the force in the direction of arrow 54 in FIG. 5, that is, the radial direction of the membrane 61 is not acting.
第６図は第３の実施例を示し、メンブレン71の外周部72
は、上記第１番目の実施例と同様に硬度アップされてい
る。本実施例では、メンブレン71のストッパ２との係合
面とは反対の面に突起物73を貼付又は一体成形してい
る。FIG. 6 shows a third embodiment, which is an outer peripheral portion 72 of the membrane 71.
Has an increased hardness as in the first embodiment. In this embodiment, the protrusion 73 is attached or integrally formed on the surface of the membrane 71 opposite to the surface for engaging the stopper 2.
同突起物73はメンブレン71がサクション状態にあるとき
リップ部73a,73bが形成され、加圧状態では第７図に示
す様に平坦に変形されて、被圧搾物の挟み込みを防止す
る。The protrusion 73 has lip portions 73a and 73b formed when the membrane 71 is in the suction state, and is deformed flat as shown in FIG. 7 in the pressurized state to prevent the object to be compressed from being caught.
つまり、ロックされる部分を無くし、かつこの部分でメ
ンブレン71を変化させないことにより挟み込み防止効果
をより発揮できるようにしている。That is, the locked portion is eliminated and the membrane 71 is not changed in this portion, so that the trapping prevention effect can be further exerted.
