で搬送（矢印Ｘ方向に搬送）される。As the above-mentioned transport support member, there is one having a structure as shown in FIGS. 4 and 5. These transport support members 2
Both 1 and 31 are made of special rubber such as synthetic rubber. The transport support member 21 shown in FIG. 4 is, so to speak, a semi-cylindrical type, in which a hollow portion 22 is formed to have elasticity, and the flat plate portion 23 side is fixed to a chain or the like via some fixing means. Then, the bottle or the like is conveyed (conveyed in the arrow X direction) with the bulging portion 24 being sandwiched between the conveyance supporting members 21 arranged so as to face each other.

け落ちも少ない。[Problems to be Solved by the Invention] In the case of the transport supporting members 21 and 31 having the above-described structure, if the outer shape of the bottle is a simple cylindrical shape which has been frequently used, the side surface of the transport supporting member and the side surface of the bottle are Has a large contact area and does not fall out.

例が見られるようになった。However, recently, deformed bottles having a constricted shape, a gourd shape, a conical shape, a grooved shape or the like have come into circulation, and a flexible container has been used more frequently than a glass bottle. Therefore, the above-described conventional transport support member 21,
In the structure of 31, the surface contact or line contact was made for a simple cylindrical bottle, but for deformed bottles or containers with a large constriction, the holding contact is point contact. As a result, the contact area with the bottle has become small, and the holding of the bottle has become unstable, and in some cases, it has fallen out.

系に加わる負荷が大きくなり、過負荷で停止する場合も
生ずる。In order to prevent this, a countermeasure can be taken by reducing the interval for sandwiching the transported object, that is, the opposing interval between the transport supporting members and increasing the frictional force. The frictional resistance between the container and other transported objects increases, the load applied to the transported object support increases and its life shortens.In addition, the load applied to the drive system such as the motor increases and overloading occurs. It may also stop.

目的とする。The present invention has been made to solve the above problems, and an object of the present invention is to provide a conveyed object supporting member which has a simple structure and is capable of reliably holding the conveyed object regardless of the shape of the conveyed object. To do.

って達成される。[Means and Actions for Solving the Problems] The object of the present invention is to provide a pair of endless rotary drives that face each other along a certain traveling guide so as to sandwich and convey a substantially cylindrical article. In the article support member continuously provided on the chain, the article support is made of an elastic member, and a plurality of convex portions along the article conveyance direction are formed on a side surface facing the article. This is achieved by the transported object support member configured such that the tip of the convex portion faces upward.

即ち、搬送物支持部材の側面に搬送する物品、例えば

めることができる。That is, since the convex portion is formed on the side surface of the conveyed object supporting member, for example, in the direction (conveying direction) orthogonal to the longitudinal direction of the bottle, the convex portion is deformed laterally on the curved side surface of the bottle. However, since it becomes flexible and each convex part can contact with a relatively large contact area, even if the bottle etc. has a non-cylindrical shape with a large constriction, The adjustment of the facing distance may be rough, and in some cases, the holding of the bottle can be guaranteed without adjusting the facing distance, and the ability to cope with the bottle shape can be enhanced.

することができる。Further, since the tip of the convex portion is configured to face upward, the force with which the convex portion holds the bottle or the like is pushed downward, for example, by the force that the bottle is about to fall. When pushed by, the convex portion acts so as to project toward the side surface of the bottle, so that a larger frictional force can be generated, and falling of a conveyed product such as a bottle can be effectively avoided.

［実施例］ 以下、第１図を参照して本考案を適用した搬送物支持
部材の第１実施例を説明する。[Embodiment] A first embodiment of a conveyed object supporting member to which the present invention is applied will be described below with reference to FIG.

置として構成されることになる。The support member 1 sandwiches and transports a substantially cylindrical article continuously, and is used by being appropriately attached to an endless article such as a pair of chains (not shown). The attachment of the support member 1 to the chain is appropriately fixed on the flat plate portion 5 side via an attachment member. Therefore, although not shown, the carrier device having the support members 1 is, for example, between the support members 1 continuously arranged on a chain incorporated in a guide means that is connected to a drive system and constitutes a certain transfer path. Thus, the device is configured as a device that holds and conveys the bin 4.

前記支持部材１はその全体形状は角柱状であって弾性

ン４の横断面方向、即ち、ビン４の搬送方向Ｘに沿った
方向である。また、凸部３はその先端3aが上方に向べく
適宜反り返るように構成されている。The support member 1 has a prismatic shape as a whole and is made of an elastic material, and has a plurality of convex portions 3 formed on one side surface facing the bottle 4. Therefore, the groove portion 2 is naturally formed between the convex portions 3. The forming direction of the convex portion 3 is the cross-sectional direction of the bin 4, that is, the direction along the transport direction X of the bin 4. Further, the convex portion 3 is configured such that the tip 3a thereof is appropriately warped upward.

支持部材１によって第１図に示すように中程がくびれ
たビン４を挟持する場合、上方及び下方の凸部３はビン
４の大径部分に対応して比較的大きくへこむようにビン
側面に当接する一方、中段の凸部３は上下のものに比較

することができる。なお、支持部材１の材質について
は、柔軟性があり且つ高摩擦のものが好ましく、例えば
軟質合成ゴムのような特殊ゴム，あるいはウレタン系、
ポリエチレン系の弾性材料で構成することができる。When the support member 1 holds the bottle 4 having a narrowed middle portion as shown in FIG. 1, the upper and lower convex portions 3 are formed on the side surface of the bottle so as to be relatively largely dented corresponding to the large diameter portion of the bottle 4. On the other hand, the convex portion 3 in the middle stage can come into contact with the bottle neck portion without being recessed so much as compared with the upper and lower ones. The material of the support member 1 is preferably flexible and has high friction, such as special rubber such as soft synthetic rubber or urethane-based material.
It can be made of a polyethylene-based elastic material.

このように、この凸部３がビン４の湾曲した側面に横
方向から変形しながら柔軟に対応することができ、ビン
４に対して非接触な状態になる凹部３は一つもなく、且

支持体の対向間隔の調整は比較的ラフでよく、また、場
合によっては対向間隔を調整しなくともビン保持が保証
でき、ビン形状に対する対応能力を高めることができ
る。In this way, the convex portion 3 can flexibly deal with the curved side surface of the bottle 4 while being deformed from the lateral direction, and there is no concave portion 3 that is in a non-contact state with the bottle 4, and Since the part 3 is made of an elastic material and has a fold shape, it has high flexibility and can contact the bottle 4 with a relatively large contact area. Therefore, even if the bottle has a non-cylindrical shape with a large constriction, it is possible to flexibly obtain a large frictional force and adjust the facing distance of the conveyed object support even for different shaped bottles. Can be relatively rough, and in some cases, the holding of the bottle can be guaranteed without adjusting the facing distance, and the ability to cope with the bottle shape can be improved.

また、当然のことながら重力によりビン４は例えば矢

くびれ部分に対応した凸部３はその上方に位置するビン
大径部により下方に押されることもあり、これによって
該凸部３はビン側面方向に更に張り出すようになること
による引っ掛け作用も加わり、抜け落ちは極めて効果的
に防止される。Naturally, due to gravity, the bottle 4 tries to fall, for example, in the direction directly below as shown by the arrow A, but since the convex portion 3 is diagonally upward, the convex portion 3 and the side surface of the bin are caused by the force in the falling direction. The abutting force of is increased, especially
The convex portion 3 corresponding to the constricted portion may be pushed downward by the large-diameter portion of the bottle located above the constricted portion, so that the convex portion 3 further extends in the side surface direction of the bottle, which also adds a hooking action. The falling out is extremely effectively prevented.

次に、第２図を参照して第２実施例について説明す
る。Next, a second embodiment will be described with reference to FIG.

一定に揃っているものの、山の高さは異なり、下部寄り
になるにつれて凸部３の変形能力が増大するように構成
されている。なお、チェーンへの固定は、前記同様に平
板部15によって行われる。The support member 11 in this embodiment is such that the depth d of the groove 12 is changed so as to increase from the top to the bottom. Therefore, although the protrusions 13 have the same amount of protrusion at the top (tip), the heights of the ridges are different, and the deformability of the protrusions 3 increases toward the bottom. ing. Note that the fixing to the chain is performed by the flat plate portion 15 as described above.

本実施例に示した支持部材11は、仮想線で示したよう

送が期待できる。The support member 11 shown in this embodiment is suitable for holding the large-diameter bottle 14 on the lower side as shown by the phantom line.
That is, since the elasticity of each convex portion 13 is deformed in accordance with the shape of the bottle 14, that is, the deep constricted portion and the large convex shape, a uniform clamping force is applied to each portion of the bottle 14 for reliable clamping and Expected to be transported.

本実施例の支持部材11は凸部13の張り出し高さが同じ

して適宜構成にすることができる。Since the supporting member 11 of this embodiment is constructed so that the protrusions 13 have the same overhanging height, it can be used well for carrying a cylindrical bottle, as a matter of course. Further, the change in size of the groove portion 12 is not limited to the configuration in which the size is gradually increased downward as described above, and can be appropriately configured according to the shape of the bin to be transported.

次に、第３図を参照して第３実施例について説明す
る。Next, a third embodiment will be described with reference to FIG.

本実施例は、前記支持部材１、11の何れに適用しても
よいものであるが、支持部材１への適用例を説明する。Although this embodiment may be applied to any of the support members 1 and 11, an application example to the support member 1 will be described.

即ち、各凸部３の一面、例えば上面にスリット６を形

向上させるようにしてもよい。That is, the slits 6 are formed on one surface of each convex portion 3, for example, the upper surface, and the deformability of each convex portion 3 is further improved. By forming the slit 6, each convex portion 3 can be deformed so as to cling to the outer surface of the bottle 4, and the clamping force is improved. Further, as shown by a dotted line, a hollow portion 7 may be formed in the longitudinal direction of the support member 1 to improve the deformability of the support member 1 as a whole.

更に、各溝部２に連続して点線で示すような深い切れ
目８を形成してもよい。Further, a deep cut 8 as shown by a dotted line may be formed continuously in each groove 2.

各実施例に説明した支持部材１、11は摩擦力と弾性力

のビン形状に対応することができる。Since the support members 1 and 11 described in the respective embodiments can obtain a sandwiching force that is a synergistic effect of frictional force and elastic force, the sandwiching interval can be precisely adjusted according to the shape of the conveyed object, like the conventional support member. There is no need, and the spacing adjustment can be rough. Therefore, the support members 1 and 11 can obtain a large frictional force without narrowing the space between them and increasing the contact force with the bottle, and the above-mentioned structure can be achieved without providing a complicated adjusting mechanism for adjusting the space. The desired clamping force can be obtained with a simple structure, and various bottle shapes can be accommodated.

また、ビン４、14と支持部材１、11との当接力を小さく
できることから、ビン挟持時の過負荷状態の発生を回避
できるので、モータ容量も小さくできる。Further, since the abutting force between the bins 4 and 14 and the supporting members 1 and 11 can be reduced, it is possible to avoid the occurrence of an overload state when the bins are clamped, so that the motor capacity can be reduced.

［考案の効果］ 以上に説明したように、本考案に係る搬送物支持部材

成されたものである。[Advantages of the Invention] As described above, the transported object support member according to the present invention is made of an elastic member, and the side surface facing the article has a plurality of protrusions along the article transport direction. The projection is formed so that the tip of the projection faces upward.

ができる。Therefore, since an article to be conveyed is formed on the side surface of the conveyed object supporting member, for example, a convex portion is formed in a direction (conveying direction) orthogonal to the longitudinal direction of the bottle, the convex portion is laterally formed on the curved side surface of the bottle. It becomes flexible while deforming, and since each convex part can contact with a relatively large contact area, even if the bottle etc. has a non-cylindrical shape with a large constriction, Adjustment of the facing distance may be rough, and in some cases, bin holding can be guaranteed without adjusting the facing distance, the ability to cope with the shape of the bottle can be enhanced, and even if the transported object is easily deformed,
Since a large frictional force can be obtained even if the abutting force of the conveyed product support is not large, the conveyed product can be reliably held. Further, since the tip of the convex portion is configured to face upward, the force for holding the bottle or the like by the convex portion is pushed downward by the force of the bottle trying to drop, for example.
By being pushed downward, the convex portion acts so as to project toward the side surface of the bottle, so that a larger frictional force can be generated and the dropping of the bottle can be effectively avoided.

このように本考案の搬送物支持部材よれば、構造が簡
単である上に、搬送物の形状の如何に拘らず確実に挟持

It can also be provided.
