Description

The present invention relates to a flexible member taking-out device for taking out a flat flexible member such as a pouch laminated in multiple rows inside a container.

Conventionally, when a predetermined fluid is filled in a pouch, a container in which an empty flat pouch is laminated is conveyed before the fluid is filled, and the pouch is sequentially charged from the container using a suction head such as a robot hand. It is taken out while being adsorbed and held, and then transported to a fluid filling machine (see, for example, Patent Documents 1 and 2).

Then, as shown in FIG. 7, in order to accommodate as many pouches as possible in the container, the pouches are laminated in multiple rows in the container.

Japanese Unexamined Patent Publication No. 5-124751 Japanese Unexamined Patent Publication No. 2007-39113

However, in the process of transporting the container, the pouches may be disturbed or displaced inside the container, so that the ends of the pouches in adjacent rows may overlap each other inside the container. In such a state, if the uppermost pouch in a certain row is sucked and held by the suction head and lifted, the end of the pouch in the adjacent row may be caught and the pouch in the adjacent row may be inadvertently lifted. Since problems such as turning over or being greatly displaced occur, there is a problem that the operation of taking out the pouch is hindered thereafter.

It should be noted that such a problem occurs not only in the pouch but also in the case of a flat flexible member.

The present invention has been made in view of the above problems and has an effect on the flexible members of the adjacent rows even when the ends of the flexible members of the adjacent rows overlap each other inside the container. It is an object of the present invention to provide a flexible member taking-out device capable of easily and surely taking out a flexible member from a container while reducing the problem.

The present invention is a flexible member taking-out device for taking out flat flexible members laminated in multiple rows inside a container in order to achieve the above object, and the surface of the uppermost flexible member. The holding portion is provided with a holding portion for holding and lifting the holding portion, and an abutting portion provided around the holding portion. The abutting portion abuts on the surface of the flexible member in a state of being relatively above the abutting portion, so that the flexible member faces the abutting portion side with the holding portion as the apex. It is characterized by bending downward.

According to this, when the surface of the uppermost flexible member is held and lifted by the holding portion, the flexible member curves downward toward the contact portion with the holding portion as the apex, and thus the inside of the container. Even when the ends of the flexible members in the adjacent rows overlap each other, the flexible members can be easily and reliably removed from the container while reducing the influence on the flexible members in the adjacent rows. ..

Further, when the surface of the uppermost flexible member is held and lifted by the holding portion, the holding portion is positioned relatively below the contact portion, so that the holding portion is the contact portion. It is preferable to displace to a state where it is located relatively upward. According to this, since the holding portion is initially located relatively below the contact portion, the holding portion can reliably hold the surface of the flexible member. Further, since the holding portion is located relatively above the abutting portion, the flexible member can be curved downward toward the abutting portion side with the holding portion as the apex.

Further, the holding portion may be moved so as to be located above the contact portion when holding and lifting the surface of the uppermost flexible member. According to this, by moving the holding portion so as to be located above the abutting portion, the holding portion is located relatively below the abutting portion, and the holding portion is located above the abutting portion. It can be displaced to a state where it is located relatively upward.

Further, the holding portion is configured to be expandable and contractible in the stacking direction of the flexible member, and contracts so as to be located above the contact portion when the surface of the uppermost flexible member is held and lifted. You may. According to this, the holding portion can be easily positioned above the abutting portion by the contracting operation of the holding portion.

Further, the holding portion may include a suction cup that holds the surface of the uppermost flexible member by suction. According to this, the holding portion can surely hold the surface of the flexible member by adsorption.

Further, the holding portion may be provided with a plurality of suction cups in the stacking direction of the flexible members. According to this, each suction cup contracts in the stacking direction of the flexible member, so that the holding portion can be contracted so as to be located above the contact portion.

Further, it is preferable that the contact portions are provided on both sides of the holding portion. According to this, since the flexible member curves downward toward both sides with the holding portion as the apex, it can be universally used for taking out the flexible member in each row. Further, when the flexible members are laminated in three or more rows, the influence of the rows adjacent to both sides on the flexible members can be reduced at the same time.

Further, the contact portion may be provided so as to be movable in the stacking direction of the flexible members. According to this, when a force exceeding a predetermined value is applied to the abutting portion from the laminated body of the flexible member, the abutting portion moves upward to prevent an excessive load from being applied to the abutting portion. can do. Further, when the holding portion holds the surface of the uppermost flexible member, the contact portion can appropriately press the surface of the uppermost flexible member on the laminate.

Further, the contact portion may be moved so as to be located below the holding portion when the surface of the uppermost flexible member is held and lifted by the holding portion. According to this, by moving the contact portion so as to be located below the holding portion, the holding portion is positioned relatively below the contact portion, and the holding portion is located below the contact portion. It can be displaced to a state where it is located relatively upward.

Further, the contact portion may be made of an elastic body that can be deformed in the plane direction of the flexible member. According to this, when the abutting portion abuts on the surface of the uppermost flexible member, it can be prevented from being added more than necessary to the abutting portion by being deformed in the plane direction. Further, when the holding portion holds the surface of the uppermost flexible member, the contact portion can appropriately press the surface of the uppermost flexible member on the laminate.

According to the present invention, when the surface of the uppermost flexible member is held and lifted by the holding portion, the flexible member curves downward toward the abutting portion side with the holding portion as the apex of the container. Even when the ends of the flexible members in adjacent rows overlap each other inside, the flexible members can be easily and reliably removed from the container while reducing the effect on the flexible members in the adjacent rows. can.

<First Embodiment>
Next, a first embodiment of the flexible member taking-out device (hereinafter referred to as the present device) according to the present invention will be described with reference to FIGS. 1 to 5 and 7.

In this embodiment, as shown in FIG. 7, each laminated body PS is configured by laminating pouches P as flexible members in two rows on a container D such as a corrugated cardboard box. A case will be described in which the pouches P of the laminated body PS in one row stacked on the container D are taken out in order from the top.

The present apparatus includes a base 1 extending in the length direction of the pouch P laminated on the container D, two holding portions 2 provided in the base 1 along the length direction of the pouch P, and the holding portion 2. Both sides of the pouch P in the width direction are provided with three contact portions 3 provided on the base portion 1 along the length direction of the pouch P.

As shown in FIGS. 1 and 2, the base portion 1 has a support plate 11 that supports the holding portion 2 and the contact portion 3, and a side view U-shaped frame provided on the upper surface of the support plate 11. A plate 12 and two suction tubes 13 provided on the upper surface of the support plate 11 at predetermined intervals along the length direction of the pouch P are provided, and the pouch P is laminated in the stacking direction (up and down) by a drive mechanism (not shown). It is configured to be movable in the direction). The upper end of the suction pipe 13 is connected to an air suction device (not shown) in a communicating state, and the lower end is connected to a suction cup 23 described later in a communicating state.

As shown in FIGS. 1 and 2, the holding portions 2 are two support bar members provided at predetermined intervals along the length direction of the pouch P on the lower surface of the support plate 11 of the base 1. The support cup member 22 having an upper surface opening slidably provided on the 21 and 21 and the two support bar members 21 and 21 along the stacking direction of the pouch P, and the pouch P laminated on the support cup member 22. It is provided with a suction cup 23 provided along the direction.

The suction cup 23 is made of an elastic body formed in a cylindrical bellows shape, and has a first suction cup 231 having a lower end opening whose upper end is connected to the lower surface of the bottom of the support cup member 22 and a support cup member whose lower end is a support cup member. A second suction cup 232 connected to the upper surface of the bottom of 22 and a third suction cup having a lower end connected to the upper end of the second suction cup 232 and an upper end connected to the lower surface of the support plate 11. It is equipped with 233.

Further, the first, second and third suction cups 231 and 232, 233 are communicated with each other in a state where air can flow to each other, and the lower end portion of the first suction cup 231 is operated by the operation of the air suction device. By sucking air from, the surface of the pouch P in contact with the lower end of the first suction cup 231 is sucked and held.

Therefore, when the surface of the uppermost pouch P laminated inside the container D is sucked and held by the first suction cup 231 of the holding portion 2, the lower end portion of the first suction cup 231 is closed by the pouch P. Then, the insides of the first, second and third suction cups 231 and 232, 233 are in a negative pressure state, and the first, second and third suction cups 231 and 232, 233 are all pouches. It shrinks in the stacking direction of P. Therefore, by the contraction operation of the first, second and third suction cups 231 and 232, 233 of the holding portion 2, the holding portion 2 can be moved so as to be located above the contact portion 3. It is possible to displace the holding portion 2 from a state in which the holding portion 2 is located relatively below the abutting portion 3 to a state in which the holding portion 2 is located relatively above the abutting portion 3.

When the second and third suction cups 232 and 233 contract, the support cup member 22 connected to the second suction cup 232 moves upward along the support bar member 21. , 2nd and 3rd suction cups 232 and 233 can be retracted in the vertical direction.

The specific operation of the holding unit 2 will be described in detail in an operation example of the present device described later.

The contact portions 3 are provided on the support plates 11 of the base portion 1 with two support pipes 31 and 31 provided at predetermined intervals along the length direction of the pouch P, and the support pipes 31 and 31 respectively. It includes two support bar members 32, 32 inserted, a contact plate 33 provided at the lower ends of the support bar members 32, 32, and a spring member 34 for urging the support bar member 32 downward. ..

The support bar member 32 is movable inside the support tube 31 in the stacking direction of the pouch P, a rib 32a for stopping movement is formed at the upper end portion, and the spring member 34 is stopped at the lower end portion. A large diameter portion 32b is formed.

The contact plate 33 is made of a thin rigid body having a rectangular shape in a side view, is arranged in an upright state in the stacking direction of the pouch P, and its lower end portion abuts on the surface of the pouch P.

The upper end of the spring member 34 is locked to the lower end of the support tube 31, and the lower end is locked to the large diameter portion 32b of the support bar member 32, so that the spring member 34 is compressed by a predetermined length in the stacking direction of the pouch P. The support bar member 32 is urged downward by being provided in this state. The urging force of the spring member 34 at this time is adjusted so that the support bar member 32 can move upward when a force of a predetermined value or more is applied.

Therefore, in a normal state where the contact plate 33 of the contact portion 3 is not in contact with the pouch P, the support bar member 32 protrudes downward from the support plate 11 by being urged downward by the spring member 34. The rib 32a is in contact with the support tube 31 and is stopped at the lowest position (see the state of the second and third contact portions 3 from the left side in FIG. 3).

Further, when the contact plate 33 of the contact portion 3 comes into contact with the surface of the pouch P and a predetermined force or more is applied to the contact plate 33, the support bar member 32 comes into contact with the pouch P of the contact plate 33. Depending on the degree, it moves upward while resisting the urging force of the spring member 34 (see the state of the first contact portion 3 from the left side in FIG. 3). For example, when the uppermost pouch P is still laminated on the laminated body PS of the lower pouch P, the contact plate 33 of the contact portion 3 is further pressed against the pouch P in a state of being in contact with the uppermost pouch P. Then, the support bar member 32 moves upward according to the degree of contact of the pouch P by receiving a reaction force of a predetermined value or more from the laminated body PS.

In this way, when a predetermined force or more is applied to the contact portion 3 from the laminated body PS of the pouch P, the contact portion 3 moves upward, so that an excessive load is applied to the contact portion 3. Can be prevented. Further, when the holding portion 2 holds the surface of the uppermost pouch P, the contact portion 3 can appropriately press the surface of the uppermost pouch P on the laminated body PS.

Further, even if the contact plate 33 of the contact portion 3 comes into contact with the surface of the pouch P, if a force equal to or higher than a predetermined force is not applied to the contact plate 33, the support bar member 32 does not move upward and is the most maximum. The stopped state is maintained in the lower position (see the state of the second and third contact portions 3 from the left side in FIG. 3). For example, when the uppermost pouch P is separated from the laminated body PS of the lower pouch P, the contact plate 33 of the contact portion 3 becomes the uppermost pouch P as the holding portion 2 moves upward. Even if the support bar member 32 is further pressed against the pouch P in the abutted state, it usually does not receive a force equal to or higher than a predetermined value, so that the support bar member 32 does not move upward and maintains a state of being stopped at the lowest position.

The operation of the contact portion 3 will be described in detail in an operation example of the present device described later.

Next, a first operation example of this apparatus will be described with reference to FIG. A case will be described in which the container D in which the pouches P are stacked in two rows is transported to a predetermined position below the apparatus, and then the uppermost pouch P in the laminated body PS in a certain row is held and lifted. Further, in this operation example, it is assumed that the pouches P on the uppermost layer are in a parallel state.

First, as shown in FIG. 4A, the apparatus starts moving downward. In the holding portion 2, the first, second and third suction cups 231 and 232, 233 are naturally stretched by their own weight, and are in the most stretched state as a whole. Further, in the contact portion 3, the support bar member 32 is urged downward by the spring member 34 so as to project downward from the support plate 11 and stop at the lowest position. At this time, in this device, the holding portion 2 is located relatively below the contact portion 3.

Next, as shown in FIG. 4B, when the device moves downward, in the holding portion 2, the first suction cup 231 comes into contact with the surface of the central portion of the pouch P, and the air suction device operates. Starts adsorption and retention of the surface of the central portion of the pouch P. Further, in the contact portion 3, the support bar member 32 is stopped at the lowest position. At this time, in this device, the holding portion 2 is maintained in a state of being relatively lower than the contact portion 3.

Next, as shown in FIG. 4 (c), when the apparatus further moves downward, in the holding portion 2, the first suction cup 231 sucks and holds the surface of the central portion of the pouch P, and the first, first, The second and third suction cups 231, 232, and 233 contract in the stacking direction of the pouch P, so that the suction cups 231 and 233 are in a contracted state as a whole. Further, in the contact portion 3, the contact plate 33 comes into contact with the surfaces on both sides of the central portion of the pouch P while the support bar member 32 stops at the lowest position. At this time, in this device, the lower end of the first suction cup 231 of the holding portion 2 and the lower end of the contact plate 33 of the contact portion 3 are at the same height, and the holding portion 2 and the contact portion 3 are the same. It is in the height position.

Next, as shown in FIG. 4 (d), when the device is stopped and more air is sucked by the air suction device, the first suction cup 231 is placed on the surface of the central portion of the pouch P in the holding portion 2. The first, second, and third suction cups 231 and 232, 233 further contract in the stacking direction while adsorbing and holding the above-mentioned, so that the state is the most contracted as a whole. Further, in the contact portion 3, the contact plate 33 is in contact with the surfaces on both sides of the central portion of the pouch P while the support bar member 32 is stopped at the lowest position. At this time, in the present apparatus, the lower end portion of the first suction cup 231 of the holding portion 2 is located above the lower end portion of the contact plate 33 of the contact portion 3, so that the holding portion 2 is positioned at the contact portion 3. It is displaced to a state where it is located relatively above. Therefore, the pouch P is curved downward from the holding portion (central portion) by the holding portion 2 to the contact portion by the contact portion 3. Since the portion outside the contact portion of the pouch P is still laminated on the laminated body PS of the lower pouch P, it is in a state parallel to the laminated body PS.

Next, as shown in FIG. 4 (e), when the apparatus moves upward, the first suction cup 231 lifts the holding portion 2 while sucking and holding the surface of the central portion of the pouch P. Further, in the contact portion 3, the contact plate 32 is in contact with the surfaces on both sides of the central portion of the pouch P while the support bar member 32 is stopped at the lowest position. At this time, in this device, the holding portion 2 is maintained in a state of being relatively above the contact portion 3, and the pouch P is completely separated from the laminated body PS of the lower pouch P. Therefore, the pouch P is curved downward from the holding portion (central portion) by the holding portion 2 to the contact portion by the contact portion 3, and the outer portion of the contact portion is also curved downward due to its own weight. As a whole, it curves downward so as to draw a gentle curve.

Therefore, when the surface of the uppermost pouch P is held and lifted by the holding portion 2, the pouch P is adjacent inside the container D because the pouch P curves downward toward the abutting portion side with the holding portion as the apex. Even when the ends of the pouches P in the row overlap each other, the pouch P can be easily and surely taken out from the container D while reducing the influence of the laminated body PS of the adjacent rows on the pouch P.

Next, a second operation example of the present device will be described with reference to FIG. In this operation example, it is assumed that the pouch P is tilted upward on the right side.

First, as shown in FIG. 5A, the apparatus starts moving downward. In the holding portion 2, the first, second and third suction cups 231 and 232, 233 are naturally stretched by their own weight, and are in the most stretched state as a whole. Further, in the contact portion 3, the support bar member 32 is urged downward by the spring member 34 so as to project downward from the support plate 11 and stop at the lowest position. At this time, in this device, the holding portion 2 is located relatively below the contact portion 3.

Next, as shown in FIG. 5B, when the device moves downward, in the holding portion 2, the first suction cup 231 comes into contact with the surface of the central portion of the pouch P, and the air suction device operates. Starts adsorption and retention of the surface of the central portion of the pouch P. Further, in the contact portion 3, the support bar member 32 is stopped at the lowest position. At this time, in this device, the holding portion 2 is maintained in a state of being relatively lower than the contact portion 3.

Next, as shown in FIG. 5 (c), when the apparatus further moves downward, in the holding portion 2, the first suction cup 231 sucks and holds the surface of the central portion of the pouch P, and the first, first, The second and third suction cups 231 and 232, 233 contract in the stacking direction, so that the suction cups 231 and 232 and 233 are in the most contracted state as a whole. Further, in the contact portion 3 on the right side, the contact plate 33 abuts on the surface on the right side in the width direction of the pouch P, and the support bar member 32 receives a reaction force from the laminated body PS of the pouch P and the pouch P receives a reaction force. It moves upward according to the degree of contact. On the other hand, in the contact portion 3 on the left side, the support bar member 32 is stopped at the lowest position, and the contact plate 33 is not yet in contact with the surface on the left side in the width direction of the pouch P. At this time, in this device, the lower end of the first suction cup 231 of the holding portion 2 is at the same height as the lower end of the contact plate 33 of the contact portion 3 on the right side, but the contact portion on the left side. It is located above the lower end of the contact plate 33 of 3.

Next, as shown in FIG. 5D, when the apparatus moves upward, the first suction cup 231 lifts the pouch P while sucking and holding the surface of the central portion of the pouch P in the holding portion 2. Further, in the contact portion 3 on the right side, the reaction force from the laminated body PS of the pouch P disappears as the uppermost pouch P is lifted, so that the contact plate 33 is the surface on the right side in the width direction of the pouch P. The support bar member 32 moves downward and returns to the lowest position while abutting against. Further, in the contact portion 3 on the left side, the contact plate 33 abuts on the surface on the left side of the central portion of the pouch P while the support bar member 32 stops at the lowest position. At this time, in the present apparatus, the lower end portion of the first suction cup 231 of the holding portion 2 is located above the lower end portion of the abutting plate 33 of the abutting portion 3, so that the holding portion 2 is a contact portion 3. It is displaced to a state where it is located relatively above. Therefore, in the pouch P, both sides of the central portion are curved downward to the abutting portion, with the holding portion (central portion) by the holding portion 2 as the apex. The portion on the left side of the contact portion of the pouch P by the contact portion 2 on the left side is curved downward due to its own weight away from the laminated body PS of the lower pouch P, but the pouch by the contact portion 2 on the right side. The portion on the right side of the contact portion of P is still inclined upward along the laminated body PS of the lower pouch P.

Next, as shown in FIG. 5 (e), when the apparatus moves further upward, the first suction cup 231 lifts the pouch P while sucking and holding the surface of the central portion of the pouch P in the holding portion 2. .. Further, in the contact portion 3, the contact plate 33 is in contact with the surfaces on both sides of the central portion of the pouch P while the support bar member 32 is stopped at the lowest position. At this time, in this device, the holding portion 2 is maintained in a state of being relatively above the contact portion 3, and the pouch P is completely separated from the laminated body PS of the lower pouch P. Therefore, the pouch P is curved from the holding portion (central portion) by the holding portion 2 to the abutting portion by the abutting portion 3, and the portion outside the corresponding contact portion is also separated from the laminated body PS by its own weight. It curves downwards and curves downward so as to draw a gentle curve as a whole.

<Second embodiment>
Next, a second embodiment of the present apparatus will be described with reference to FIG. In the following, only the configurations different from the above-described embodiment will be described, and the same configurations will be omitted and the same reference numerals will be given.

In the first embodiment, when the holding portion 2 is displaced from the state where it is located relatively below the contact portion 3 to the state where the holding portion 2 is located relatively above the contact portion 3, the holding portion 2 is displaced. The holding portion 2 is moved so as to be positioned above the contact portion 3, but in the present embodiment, the contact portion 3 is moved so as to be positioned below the holding portion 2. It is configured in. Specifically, the support bar member 32 of the contact portion 3 is configured to be movable in the stacking direction (vertical direction) of the pouch P by a drive mechanism (not shown).

An operation example according to the second embodiment of the present apparatus will be described with reference to FIG.

First, as shown in FIG. 6A, the apparatus starts moving downward. In the holding portion 2, the first, second and third suction cups 231 and 232, 233 are naturally stretched by their own weight, and are in the most stretched state as a whole. Further, in the contact portion 3, the support bar member 32 is stopped at an upper position. At this time, in this device, the holding portion 2 is located relatively below the contact portion 3.

Next, as shown in FIG. 6B, when the device moves downward, in the holding portion 2, the first suction cup 231 comes into contact with the surface of the central portion of the pouch P, and the air suction device operates. Starts adsorption and retention of the surface of the central portion of the pouch P. Further, in the contact portion 3, the support bar member 32 is stopped at an upper position, and the contact plate 33 is not in contact with the surfaces on both sides of the central portion of the pouch P. At this time, in this device, the holding portion 2 is maintained in a state of being relatively lower than the contact portion 3.

Next, as shown in FIG. 6C, when the device is stopped and more air is sucked by the air suction device, in the holding portion 2, the first suction cup 231 is the surface of the central portion of the pouch P. Shrinks in the stacking direction of the pouch P while adsorbing and holding. Further, in the abutting portion 3, the abutting plate 33 abuts on the surfaces on both sides of the central portion of the pouch P by moving the support bar member 32 downward. At this time, in the present apparatus, the lower end portion of the first suction cup 231 of the holding portion 2 is located slightly above the lower end portion of the contact plate 33 of the contact portion 3, so that the holding portion 2 comes into contact with the holding portion 2. It is displaced to a state where it is located relatively slightly above the portion 3. Therefore, the pouch P is slightly curved downward from the holding portion (central portion) by the holding portion 2 to the contact portion by the contact portion 3. Since the portion outside the contact portion of the pouch P is still laminated on the laminated body PS of the lower pouch P, it is in a state of being substantially parallel to the laminated body PS.

Next, as shown in FIG. 6D, when the apparatus moves upward, in the holding portion 2, the first suction cup 231 lifts the pouch P while sucking and holding the surface of the central portion. .. Further, in the contact portion 3, the support bar member 32 moves further downward and is in contact with the surfaces on both sides of the central portion of the pouch P at the lowest position. At this time, in the present apparatus, the holding portion 2 is located relatively above the contact portion 3, and most of the pouch P is separated from the laminated body PS of the lower pouch P. Therefore, the pouch P is curved downward from the holding portion (central portion) by the holding portion 2 to the contact portion by the contact portion 3, and the outer portion of the contact portion is also substantially curved downward due to its own weight. Then, it curves downward so as to draw a gentle curve as a whole, leaving both ends.

Next, as shown in FIG. 6E, when the apparatus moves further upward, the first suction cup 231 sucks and holds the surface of the central portion of the pouch P in the holding portion 2 accordingly. lift. Further, in the contact portion 3, the contact plate 33 is in contact with the surfaces on both sides of the central portion of the pouch P while the support bar member 32 is stopped at the lowest position. At this time, in this device, the holding portion 2 is maintained in a state of being relatively above the contact portion 3, and the pouch P is completely separated from the laminated body PS of the lower pouch P. Therefore, the pouch P curves downward to the abutting portion with the holding portion (central portion) by the holding portion 2 as the apex, and the outer portion of the abutting portion also curves downward due to its own weight, and is gentle as a whole. It curves downward so as to draw a nice curve.

In each of the above embodiments, the holding portion 2 sucks and holds the pouch P by the suction cup 23, but the pouch may be held by other members or methods.

Further, although the holding portion 2 is configured to be expandable and contractible in the stacking direction of the pouch P by the suction cup 23, it may be configured to be expandable and contractible by another mechanism.

Further, although the holding portion 2 is configured to be able to move in the stacking direction of the pouch P due to the expandable configuration in the first embodiment, it may be moved in the stacking direction of the pouch P by another configuration.

Further, although the contact portions 3 are provided on both sides of the central portion of the pouch P in the holding portion 2, they may be provided on only one side in the width direction depending on the flexible member to be held, or in other directions. It may be provided in. However, when the contact portions 3 are provided on both sides of the holding portion 2, the pouch P is curved downward toward both sides with the holding portion as the apex, so that it can be generally used for taking out the pouch P in each row. can. Further, when the pouches P are stacked in three or more rows, the influence on the flexible members of the rows adjacent to both sides can be reduced at the same time.

Further, although the contact plate 33 of the contact portion 3 is made of a rigid body, it may be made of other members such as an elastic body. For example, the contact plate 33 of the contact portion 3 may be an elastic body that can be deformed in the plane direction of the pouch P.

Further, when the surface of the uppermost pouch P is held and lifted by the holding portion 2, the holding portion 2 is located relatively below the contact portion 3, and the holding portion 2 is located above the contact portion 3. Although it is assumed that the pouch P is displaced to a relatively upward position, the holding portion 2 may be relatively above the contact portion 3 before the pouch P is held. In this case, in order to securely hold the surface of the pouch P by the holding portion 2, the contact plate 33 of the contact portion 3 is preferably made of an elastic body that can be deformed in the plane direction of the pouch.
