(Problems to be solved by the invention)
When constructing a device for taking out a storage bag and an object to be stored such as a screw stored in the storage bag from each storage unit, the first take-out device disclosed in Patent Literature 1 and Patent Literature 2 are disclosed. It is possible to combine two of the second extraction devices disclosed in. However, since the first take-out device requires an electric mechanism for rotationally driving the endless strip, and the second take-out device requires an electric circuit and sensors, the two take-out devices are combined. Has a complicated structure. Moreover, even if two take-out devices are combined, the efficiency is poor because it is necessary to individually take out the magnetic article and the empty bag.

  Accordingly, the present invention has been made in view of the above points, and one of its purposes is to efficiently store a storage bag and an object to be stored in the storage bag from each storage unit with a simple structure. An object of the present invention is to provide an extraction device effective for extraction.

(Means for solving the problem)
In order to achieve the above object, the storage bag and the storage device take-out device according to the present invention are devices for taking out the storage bag and the storage product stored in the storage bag from each storage unit, A first storage unit, a second storage unit, a support column, a first rotating member, a second rotating member, a first holding mechanism, and a second holding mechanism are provided.

  The first storage unit stores a plurality of stacked storage bags. The second storage unit stores a plurality of items to be stored. The first rotating member is rotatably supported by the support via the first support shaft, and is rotated from the initial position to the use position by the pushing operation by the operator's finger, while the first rotating member is initialized by releasing the pushing operation. It is configured to return to the position. The second rotation member is rotatably supported by the support via the second support shaft, and the initial position and the use position are interlocked with the rotation between the initial position and the use position of the first rotation member. It is comprised so that it may rotate between. That is, when the first rotating member is in its initial position, the second rotating member is also in its initial position, and when the first rotating member is rotated to its use position, the second rotating member is also in it. Interlocks and rotates to its use position. The first holding mechanism is attached to one of the first rotating member and the second rotating member, and the uppermost storage bag in the first storage unit at the use position of the one rotating member. Fulfills the function of holding. The second holding mechanism is attached to the other rotating member of the first rotating member and the second rotating member, and a predetermined predetermined in the second storage unit at the use position of the other rotating member. It fulfills the function of holding a number of objects.

  According to the take-out device configured as described above, when one of the rotating members rotates to the use position, the uppermost storage bag in the first storage unit is held by the first holding mechanism. Thereafter, when the one rotating member returns from the use position to the initial position, the storage bag held by the first holding mechanism is taken out from the first storage unit. Further, when the other rotating member rotates to the use position in conjunction with the rotation of one rotating member, a predetermined number of stored items in the second storage unit are held by the second holding mechanism. Thereafter, when the other rotating member returns from the use position to the initial position, a predetermined number of objects to be stored held by the second holding mechanism are taken out from the second storage unit. In this take-out device, these two take-out operations (the operation of taking out one storage bag and a predetermined number of objects to be stored in the storage bag) are first rotated by the fingers of the operator. It can be performed simultaneously by only one action of the member, which is efficient. Moreover, this take-out device does not require an electric mechanism, an electric circuit, or sensors. As a result, it is possible to efficiently take out one storage bag and a predetermined number of objects to be stored from each storage unit with a simple structure. In addition, this take-out device has the advantage of being inexpensive and having few failures because no electrical control is required.

Further, in the take-out device configured as described above , the first support shaft and the second support shaft are located at different positions of the column so that the rotation stroke of the first rotation member is different from the rotation stroke of the second rotation member. Is provided. Thereby, when there is a height difference between the position of the first storage unit and the position of the second storage unit, it is dealt with by appropriately selecting the relative positional relationship between the first support shaft and the second support shaft in the support column. be able to.

In the take-out device configured as described above, the second rotating member engages with the first rotating member so as to be interlocked with the rotation of the first rotating member, and is pushed into the first rotating member. Preferably, the weight is set so that the second rotating member is held at the initial position of the second rotating member together with the first rotating member when not. Thereby, the structure which hold | maintains a 1st rotation member in each initial position with a 2nd rotation member can be simplified using the weight of a 2nd rotation member .

  In the take-out device configured as described above, the first holding mechanism preferably includes a main body, a first arm, a second arm, a rotating roller, and an elastic member. The main body is attached to one rotating member. The first arm and the second arm are connected so as to cross each other by a connecting shaft provided in the main body, and are configured to be rotatable about the connecting shaft. A rotating roller is rotatably supported at the lower end of each of the first arm and the second arm. The elastic member performs a function of elastically urging the first arm and the second arm in a direction approaching each other. In this case, the first arm and the second arm are elastic by being pressed against the uppermost storage bag via the rotation roller when one rotation member rotates from the initial position of the rotation member to the use position. The members rotate against the elastic biasing force of the member in directions away from each other about the connecting shaft. The first arm and the second arm are connected to each other according to the elastic biasing force of the elastic member by releasing the pressing of the uppermost storage bag when one of the rotating members returns from the use position to the initial position. And the uppermost storage bag is sandwiched and held via a rotating roller. Accordingly, the uppermost storage bag in the first storage unit can be held by the first holding mechanism and taken out from the first storage unit only by operation of one action of the first rotating member by the operator's fingers.

  In the take-out device configured as described above, each of the first arm and the second arm includes a lock member that locks the rotation of the rotating roller supported by the arm in the inner direction and allows the rotation of the rotating roller in the outer direction. Is preferred. In this case, when the first arm and the second arm rotate in directions away from each other, the rotation roller of each arm rotates, so that the rotation operation of each arm can be performed smoothly. On the other hand, when the first arm and the second arm rotate in directions close to each other, the rotation of the rotation roller of each arm is locked by the lock member. The bag can be sandwiched and held securely.

  In the take-out device configured as described above, the object to be stored includes a magnetic material, and the second holding mechanism includes a predetermined number of bottomed cylindrical holding members attached to the other rotating member, and the predetermined number of holding members. It is preferable to provide a permanent magnet accommodated in each cylinder bottom. In this case, each of the predetermined number of holding members is arranged such that when the other rotating member is rotated to the use position of the rotating member, any one item to be stored in the second storage unit is attracted to the permanent magnet. Composed. Thereby, only one operation of the 1st rotation member by an operator's finger | toe hold | maintains the arbitrary one to-be-stored object in a 2nd storage part with the permanent magnet of each holding member, and takes out from a 2nd storage part. be able to. In this case, by setting the number of holding members in accordance with the necessary number of objects to be stored, it becomes possible to take out the required number of objects to be stored from the second storage unit without being excessive or insufficient.

  In the take-out device configured as described above, the second holding mechanism is configured such that the permanent magnet is movable in the cylinder radial direction of the holding member at the cylinder bottom of the holding member. In this case, since the permanent magnet can move in the cylinder of the holding member, the permanent magnet is attracted to any one object to be attracted most easily. At this time, since the extra magnetic force of the permanent magnet is difficult to reach the object to be stored other than the object to be stored, the object to be stored other than the object to be stored once adsorbed to the permanent magnet is not attracted to the permanent magnet. As a result, one holding member can reliably hold one object.

  In the take-out device having the above-described configuration, the second storage unit is disposed in the storage space at an equal interval in a direction extending in a long shape in the inclined direction of the inclined surface and intersecting the inclined direction. And a predetermined number of inclined grooves. The predetermined number of holding members are arranged at the same interval as the predetermined number of inclined grooves, and the holding member corresponds when the other rotating member rotates toward the use position of the rotating member. It is preferable to be configured to move toward the inclined groove. In this case, each holding member can be selectively moved toward a plurality of objects to be collected gathered in each inclined groove. As a result, even when the remaining number of objects to be stored in the second storage portion is reduced, each holding member can reliably hold one object to be stored.

  As described above, according to the present invention, it is possible to provide a take-out device that is effective for efficiently taking out a storage bag and an object to be stored in the storage bag from each storage unit with a simple structure. Became.

In FIG. 16, in the take-out device 100, one bag A is held by the bag holding mechanism 140 and taken out from the first storage unit 101, and four screws B are held by the screw holding mechanism 150, and the second storage unit 102. It is a figure which shows the state taken out from.

  Hereinafter, an object to be stored and an apparatus for taking out the storage bag (hereinafter also simply referred to as “take-out apparatus”) according to an embodiment of the present invention will be described with reference to the drawings. In these drawings, the horizontal direction (width direction) of the take-out device is indicated by arrow X, the vertical direction (depth direction) of the take-out device is indicated by arrow Y, and the height direction (vertical direction) of the take-out device is indicated by arrow Z. It is shown in

  As shown in FIG. 1, the take-out device 100 is a device for taking out the storage bag A and the storage object B individually from the first storage unit 101 and the second storage unit 102 that are storage locations. The storage bag A is a bag for storing a necessary number of articles B to be stored. Therefore, a necessary number of articles B can be packed in the storage bag A during the bagging operation. In the present embodiment, as an example of the storage bag A, a resin bag made of olefin-based synthetic resin (polyethylene or polypropylene) as a raw material and having a sheet shape in an unused state is used. Further, as an example of the item to be stored B, a metal screw made of a magnetic material is used. In the following description, the storage bag A and the storage object B are also simply referred to as “bag A” and “screw B”, respectively.

  As shown in FIGS. 1 and 2, the first storage unit 101 is a place for storing a plurality of stacked bags A. Specifically, the first storage unit 101 includes a storage space 101a having a cross section that exceeds the size of the bag A that is spread in a sheet shape, and a plurality of bags A are stacked and stored in the storage space 101a. Yes. The first storage unit 101 corresponds to the “first storage unit” of the present invention.

  The second storage unit 102 is a place for storing a plurality of screws B and is made of a nonmagnetic material. The second storage unit 102 includes, in the storage space 102a, an inclined surface 103, a plurality of elongated portions extending in the inclination direction of the inclined surface 103 and arranged at equal intervals in a direction intersecting the inclination direction. (Four in FIG. 1). That is, the inclined surface 103 forms an uneven surface in the direction intersecting with the inclined direction. The inclined surface 103 and the inclined groove 104 here correspond to the “inclined surface” and the “inclined groove” of the present invention, respectively. For this reason, the plurality of screws B stored in the storage space 102a of the second storage unit 102 are easily guided to the lowermost portion of the inclined surface 103 according to the inclination of the inclined surface 103, and the inclined groove 104 of the lowermost portion is provided. It is easy to gather together. The storage space 102 a is arranged at a lower position than the storage space 101 a of the first storage unit 101 in the height direction Z of the take-out device 100. The second storage unit 102 corresponds to the “second storage unit” of the present invention.

  The take-out device 100 is configured to include a column 110, a first rotating member 120, a second rotating member 130, a bag holding mechanism 140, and a screw holding mechanism 150.

  As shown in FIG. 2, the first rotating member 120 extends in a long shape along the longitudinal direction Y of the take-out device 100 between the front end portion 120a and the rear end portion 120b. The front end portion 120a is configured as an operation portion where the user operates the first rotation member 120 with fingers. Therefore, the first rotating member 120 can also be called a “push lever”. As for the 1st rotation member 120, the to-be-supported part 120c near the rear-end part 120b is engaging with the support shaft 111 provided in the support | pillar 110. FIG. For this reason, the 1st rotation member 120 is supported by the support | pillar 110 via the support shaft 111 so that rotation is possible. This support shaft 111 corresponds to the “first support shaft” of the present invention. Specifically, the first rotating member 120 is rotatable about the support shaft 111 in the directions of arrows a1 and a2 in FIG. The column 110 and the first rotating member 120 here correspond to the “column” and the “first rotating member” of the present invention, respectively. The first rotating member 120 is set to an initial position by a stopper (not shown) provided on the support 110. A bag holding mechanism 140 is attached to an attached portion 120d near the front end portion 120a of the first rotating member 120 via a bracket 121.

  The bag holding mechanism 140 is disposed above the first storage unit 101. Therefore, when the first rotating member 120 is rotated from the initial position in FIG. 2 to the predetermined use position in the arrow a2 direction by the downward pushing operation of the front end portion 120a, the bag holding mechanism 140 is moved in the first time. As the moving member 120 moves, the moving member 120 moves toward the first storage unit 101. In a state where the first rotating member 120 is rotated to the use position, the bag holding mechanism 140 enters the storage space 101a of the first storage unit 101, and is the uppermost part among the plurality of sheet-like bags A in the storage space 101a. The bag A is held. Accordingly, the bags A can be taken out from the first storage unit 101 one by one by the bag holding mechanism 140. The detailed structure of the bag holding mechanism 140 will be described later.

  Similar to the first rotating member 120, the second rotating member 130 extends in a long shape between the front end portion 130 a and the rear end portion 130 b along the longitudinal direction Y of the take-out device 100. In the second rotating member 130, a supported portion 130 c near the rear end portion 130 b is connected to a support shaft 112 provided on the column 110. For this reason, the 2nd rotation member 130 is supported by the support | pillar 110 via the support shaft 112 so that rotation is possible. The support shaft 112 corresponds to the “second support shaft” of the present invention. Specifically, the second rotating member 130 is rotatable about the support shaft 112 in the directions of arrows b1 and b2 in FIG. The second rotating member 130 is engaged with the first rotating member 120 so as to rotate in conjunction with the first rotating member 120. That is, when the first rotating member 120 is in its initial position, the second rotating member 130 is also in its initial position, and when the first rotating member 120 is rotated to its use position, the second rotating member 130 is in its initial position. The member 130 is also rotated to its use position in conjunction with it. The first rotating member 130 here corresponds to the “second rotating member” of the present invention.

  The screw holding mechanism 150 includes a plurality (four in FIG. 2) of holding members 151 respectively attached to the second rotating member 130. When the second rotating member 130 is at the use position, the second storage The holding member 151 serves to hold a predetermined number of screws B in the portion 102. This screw holding mechanism 150 corresponds to the “second holding mechanism” of the present invention. The number of holding members 151 can be set according to the number of screws B that are desired to be taken out from the second storage unit 102 at a time. Each of these holding members 151 extends in a long shape along the height direction Z of the take-out device 100 between the upper end portion 151a and the lower end portion 151b. When the first rotating member 120 is in the initial position, the four holding members 151 are arranged at equal intervals in the lateral direction X of the take-out device 100 above the inclined surface 103 of the second storage unit 102. In this case, the interval between the two adjacent holding members 151 matches the interval between the two adjacent inclined grooves 104 in the inclined surface 103. That is, the four holding members 151 are arranged at the same interval as the four inclined grooves 104, and each holding member 151 is arranged above the corresponding inclined groove 104. Accordingly, each holding member 151 is configured to move toward the corresponding inclined groove 104 when the second rotating member 130 rotates toward the use position. Each holding member 151 has an upper end portion 151a attached to the front end portion 130a of the second rotating member 130 via a support shaft 131, and the direction of the arrow c1 in FIG. It can rotate in the direction of arrow c2.

  Each holding member 151 has a bottomed cylindrical shape made of a non-magnetic material, and one permanent magnet 152 having a magnetic force capable of attracting screws B is accommodated in the bottom of the lower end portion 151b. The permanent magnet 152 is configured in a columnar shape, and the columnar diameter is configured to be smaller than the cylindrical diameter of the lower end portion 151 b and is not fixed to the holding member 151. For this reason, the permanent magnet 152 can freely move in the cylinder radial direction at the cylinder bottom of the holding member 151 within the range of the cylinder diameter of the lower end portion 151b. The holding member 151 and the permanent magnet 152 here correspond to the “holding member” and the “permanent magnet” of the present invention, respectively.

  A weight 132 is attached to the rear end portion 130 b of the second rotating member 130. In the weight 132, when the pushing operation is not performed on the first rotating member 120, the second rotating member 130 overcomes the weight of both the bag holding mechanism 140 and the screw holding mechanism 150 together with the first rotating member 120. The weight is set so as to be held at the initial position shown in FIG. Further, the lower portion 132 a of the weight 132 is configured to engage with the rear end portion 120 b of the first rotating member 120. Therefore, in the initial state where the first rotating member 120 is not pushed in, the second rotating member 130 is held at the initial position shown in FIG. 2 together with the first rotating member 120 by the weight of the weight 132. Alternatively, when the pushing operation of the first rotation member 120 is released at the use position, the second rotation member 130 is moved from the use position to the initial position shown in FIG. Return to.

  On the other hand, when the first rotating member 120 is rotated in the arrow a2 direction from the initial position in FIG. 2 by the pushing operation, the weight 132 of the second rotating member 130 is lifted by the rear end portion 120b. . As a result, the second rotating member 130 rotates in the direction of the arrow b2 from the initial position in FIG. When the second rotating member 130 is rotated in the direction of the arrow b2 in FIG. 2, the lower end portion 151b of the holding member 151 is used toward the inclined groove 104 of the inclined surface 103 in the storage space 102a of the second storage unit 102. Can be lowered to position. Thereafter, when the pushing operation of the first rotating member 120 is released, the second rotating member 130 returns to the initial position in FIG. That is, as shown by the arrow in FIG. 3, the second rotating member is interlocked with the rotation between the initial position and the use position of the first rotating member 120 (operation by the rotation stroke St <b> 1). 130 is also configured to rotate (rotation stroke St2) between the initial position and the use position.

  In this case, it is necessary to determine the rotation stroke St1 of the first rotation member 120 and the rotation stroke St2 of the second rotation member 130 according to the installation height of the corresponding storage unit. More specifically, the first storage unit 101 to which the bag holding mechanism 140 attached to the first rotating member 120 is assigned is assigned the screw holding mechanism 150 attached to the second rotating member 130. It is installed at a higher location than the second storage unit 102. Therefore, it is necessary to set the rotation stroke St2 of the second rotation member 130 to exceed the rotation stroke St1 of the first rotation member 120.

  For this purpose, in the present embodiment, for the first rotating member 120, the rotating stroke St1 of the first rotating member 120 and the rotating stroke St2 of the second rotating member 130 are different. The support shaft 111 and the support shaft 112 for the second rotating member 130 are respectively provided at different positions of the support 110. Specifically, the support shaft 111 is disposed in front of the support shaft 112 in the longitudinal direction Y of the take-out device 100, and the support shaft 111 is supported in the height direction Z of the take-out device 100. It is arranged above 112. Accordingly, the rotation stroke St1 of the first rotation member 120 and the rotation stroke St2 of the second rotation member 130 can be set to appropriate values according to the installation height of the corresponding storage unit. In addition, when the 1st storage part 101 and the 2nd storage part 102 are installed in the same height, you may comprise so that the support shaft 111 and the support shaft 112 may serve as one support shaft.

  4 and 5 are referred to for the detailed structure of the bag holding mechanism 140 described above. As shown in FIG. 4, the bag holding mechanism 140 includes a main body 140 a, a first arm 141, a second arm 142, a first rotating roller 144, a second rotating roller 145, and an elastic member (spring) 146. Yes. This bag holding mechanism 140 corresponds to the “first holding mechanism” of the present invention.

  The main body 140a is attached to the first rotating member 120 via a bracket 121. The first arm 141 and the second arm 142 are connected so as to intersect in an X shape by a connecting shaft 143 provided on the main body 140a. The first arm 141 is configured to be rotatable in the arrow d1 direction and the arrow d2 direction about the connecting shaft 143. Similarly, the second arm 142 is configured to be rotatable about the connecting shaft 143 in the directions indicated by the arrows e1 and e2. The main body 140a, the first arm 141, and the second arm 142 here correspond to the “main body”, “first arm”, and “second arm” of the present invention, respectively.

  The first rotating roller 144 is a columnar member that can rotate around the roller shaft 141 a, and is supported by the distal end portion (lower end portion) of the first arm 141. Similarly, the second rotating roller 145 is a columnar member that can rotate around the roller shaft 142 a, and is supported by the tip (lower end) of the second arm 142. Elastic bodies 144a and 145a made of a rubber material are wound around the outer circumferences of the rotating rollers 144 and 145, respectively. The rotating rollers 144 and 145 here correspond to the “rotating roller” of the present invention.

  The elastic member 146 is attached to the main body 140a, and fulfills a function of elastically urging the first arm 141 and the second arm 142 in a direction approaching each other. This elastic member 146 corresponds to the “elastic member” of the present invention. Therefore, in the state (initial state) before using the bag holding mechanism 140, the first arm 141 and the second arm 142 are set to the initial state shown in FIG. 4 by the elastic biasing force of the elastic member 146. In this initial position, the first arm 141 and the second arm 142 rotate in the direction close to each other, that is, the first arm 141 rotates in the arrow d2 direction, and the second arm 142 rotates in the arrow e2 direction. Is blocked by a stopper 149. In contrast, when the first arm 141 and the second arm 142 receive a load that overcomes the elastic biasing force of the elastic member 146, the first arm 141 and the second arm 142 rotate in a direction away from each other about the connecting shaft 143. For example, the rotation position shown in FIG. 5 can be set. Further, when the load is released at the rotational position shown in FIG. 5, the first arm 141 and the second arm 142 are close to each other about the connecting shaft 143 according to the elastic biasing force of the elastic member 146. Rotate in the direction you want. Specifically, the bag holding mechanism 140 is shown in FIG. 4 by the first arm 141 rotating in the direction of arrow d1 in FIG. 5 and the second arm 142 rotating in the direction of arrow e1 in FIG. Return to the initial state.

  A triangular first lock member (first stopper member) 147 and a second lock member (second stopper member) 148 are assigned to the first arm 141 and the second arm 142, respectively. The first lock member 147 and the second lock member 148 correspond to the “lock member” of the present invention.

  The first lock member 147 is rotatable about a stopper shaft 141b provided on the first arm 141, and is configured such that an acute-angled tip portion 147a contacts the surface of the elastic body 144a of the first rotation roller 144. Has been. The distal end portion 147a of the first lock member 147 allows the first rotating roller 144 to rotate in the clockwise direction (outward direction in FIG. 4), while the first rotating roller 144 rotates in the counterclockwise direction (FIG. 4). It functions to prevent rotational movement in the inner and inner directions.

  Similarly, the second lock member 148 can rotate around a stopper shaft 142b provided on the second arm 142, and the acute-angled tip portion 148a contacts the surface of the elastic body 145a of the second rotation roller 145. It is configured as follows. The distal end portion 148a of the second lock member 148 allows the second rotating roller 145 to rotate in the counterclockwise direction (outward direction in FIG. 4), while the second rotating roller 145 rotates in the clockwise direction (FIG. 4). It functions to prevent the rotational movement in the inner (inner direction) function (the same function as the tip 147a of the first lock member 147). This function will be described with reference to FIG. 6 by taking the second lock member 148 as an example.

  As shown in FIG. 6, the second locking member 148 tends to rotate downward about the stopper shaft 142b, that is, in the direction of the arrow g1 due to its own weight as an inherent characteristic. Here, when the second rotating roller 145 rotates in the outward direction (the direction of the arrow f1), the contact angle between the tip 148a of the second locking member 148 and the second rotating roller 145 is small. It operates in the direction away from the two-rotation roller 145 (arrow g2 direction) (see the two-dot chain line in FIG. 6). As a result, the rotation operation of the second rotation roller 145 in the outward direction (arrow f1 direction) is allowed. On the other hand, when the second rotating roller 145 rotates in the inward direction (arrow f2 direction), the friction between the tip 148a of the second lock member 148 and the elastic body 145a of the second rotating roller 145. Due to the resistance, the second lock member 148 bites the surface of the elastic body 145a of the second rotation roller 145, thereby locking the second rotation roller 145. As a result, the second lock member 148 prevents the second rotary roller 145 from rotating in the inner direction (arrow f2 direction).

  Next, the operation of the take-out device 100 configured as described above will be specifically described with reference to FIGS.

  When the bag A is packed with a necessary number of screws B in the bag A, these bags A and the required number of screws B can be taken out from the respective storage units by the take-out device 100. Specifically, as shown in FIGS. 7 and 8, the operator performs a push-in operation of pushing the front end portion 120 a of the first rotating member 120 with the finger H in the direction of the white arrow. At this time, when the pushing load by the finger H reaches the load necessary to rotate the first rotating member 120 in the direction of the arrow a2 in FIG. 120 rotates from the initial position toward the use position. As shown in FIG. 9, when the first rotating member 120 is rotated, the rear end portion 120 b lifts the weight 132 of the second rotating member 130, so that the first rotating member 120 has an arrow a <b> 2 direction. In conjunction with the rotation, the second rotation member 130 also rotates in the arrow b2 direction from the initial position toward the use position. 9 and FIG. 11 to be described later, for the sake of convenience, the first storage unit 101 is described so as to be hidden behind the second rotation member 130 in order to clarify the operation of the second rotation member 130. ing.

  In this case, the bag holding mechanism 140 attached to the first rotating member 120 is stored in the storage space 101a of the first storage unit 101 as the first rotating member 120 rotates. Move towards the upper bag A. On the other hand, the screw holding mechanism 150 attached to the second rotating member 130 is stored in the storage space 102a of the second storage unit 102 as the second rotating member 130 rotates. Move toward the screw B.

  As shown in FIGS. 10 and 11, when the first rotating member 120 is rotated to its use position, the bag holding mechanism 140 is disposed at the lower end of each of the first arm 141 and the second arm 142. The first rotating roller 144 and the second rotating roller 145 are pressed downward on the uppermost bag A stored in the storage space 101 a of the first storage unit 101. On the other hand, when the second rotating member 130 is rotated to its use position, the screw holding mechanism 150 has the lower end portion 151b of each holding member 151 corresponding to the inclined groove 104 of the inclined surface 103 in the second storage unit 102. Is pushed into.

  When the bag holding mechanism 140 is pressed downward on the uppermost bag A, the bag holding mechanism 140 changes from the initial state shown in FIG. 13 to the pressed state shown in FIG.

  Specifically, the first arm 141 and the second arm 142 are respectively connected via the first rotating roller 144 and the second rotating roller 145 when the first rotating member 120 rotates from the initial position to the use position. By being pressed against the uppermost bag A, the elastic member 146 is separated from each other around the connecting shaft 143 against the elastic biasing force (the direction of the arrow d1 (first arm 141) and the direction of the arrow e1 in FIG. 12). (Second arm 142)). At this time, the rotating rollers 144 and 145 rotate in the outward direction due to the frictional resistance between the elastic bodies 144a and 145a and the uppermost bag A. Therefore, each of the first arm 141 and the second arm 142 can be smoothly rotated, and the uppermost bag A can be prevented from receiving an unnecessary load.

  Thereafter, when the first rotating member 120 returns from the use position to the initial position, the first arm 141 and the second arm 142 are released from being pressed against the uppermost bag A, whereby the elastic biasing force of the elastic member 146 is released. Accordingly, they rotate in directions close to each other around the connecting shaft 143 (the direction of the arrow d2 (first arm 141) and the direction of the arrow e2 (second arm 142) in FIG. 13). At this time, as described above with reference to FIG. 6, the rotation of the rotating rollers 144 and 145 in the inward direction is locked by the lock members 147 and 148. As a result, the first arm 141 and the second arm 142 can securely hold the uppermost bag A so as to be sandwiched by the two rotation rollers 144 and 145 in the rotation-locked state.

  When the two rotation rollers 144 and 145 in the rotation locked state sandwich the uppermost bag A, the frictional resistance between the elastic bodies 144a and 145a and the uppermost bag A is large, and the frictional resistance between the bags A is small. Therefore, the uppermost bag A can move so as to slide on the upper surface of the second bag A below it. Further, in the process of sandwiching the uppermost bag A, as shown in FIG. 14, the edge of the uppermost bag A is slightly lifted upward with respect to the second bag A, so that the uppermost portion A gap is formed between the edge of the bag A and the edge of the second bag A, and air flows through this gap, so that the separation effect is obtained between the uppermost bag A and the second bag A. can get. As a result, it is possible to prevent the occurrence of the phenomenon that the second bag A is sandwiched at a time, and only the uppermost one bag A is selectively sandwiched by the two rotation rollers 144 and 145 in the rotation locked state. It becomes possible.

  On the other hand, in the pushed state of the screw holding mechanism 150, the permanent magnet 152 housed in the lower end portion 151 b of each holding member 151 is gathered together in the inclined groove 104 of the inclined surface 103 in the second storage unit 102. Any one of the plurality of screws B is adsorbed. In particular, the screw holding mechanism 150 can selectively move the holding members 151 toward the plurality of screws B gathered in the inclined grooves 104 in the second storage unit 102. As a result, even when the remaining number of screws B in the second storage unit 102 decreases, each holding member 151 can reliably hold one screw B. At this time, since each holding member 151 is rotatably supported by the second rotating member 130 via the support shaft 131, an arbitrary screw B is selected according to the remaining number of screws B in the second storage unit 102. Can be rotated around the support shaft 131 at an angle at which it is easy to adsorb and hold.

  Further, in the screw holding mechanism 150, as described above, the permanent magnet 152 is not fixed to the holding member 151 and can freely move in the cylinder of the holding member 151. In this case, the permanent magnet 152 has a magnetic force such that only one screw B can be attracted. For this reason, as shown in FIG. 15, the permanent magnet 152 is attracted to any one screw B that is most likely to be attracted. For example, the permanent magnet 152 moves from the position indicated by the two-dot chain line to the position indicated by the solid line. The screw B is selectively attracted to the permanent magnet 152. At this time, since the extra magnetic force of the permanent magnet 152 does not easily reach the screws B other than the screws B, the screws B other than the screws B once attracted to the permanent magnet 152 are not attracted to the permanent magnet 152. As a result, one holding member 151 can reliably hold one screw B.

  Thereafter, when the pushing operation on the front end portion 120a of the first rotating member 120 by the operator's finger H is released, both the first rotating member 120 and the second rotating member 130 are moved to the initial position by the weight of the weight 132. And return. At this time, as shown in FIG. 16, the bag holding mechanism 140 rises together with the first rotating member 120 while holding the uppermost bag A in the first storage unit 101. Accordingly, the uppermost bag A can be held by the bag holding mechanism 140 and taken out from the first storage unit 101 by only one operation of the first rotating member 120 by the operator's finger H. In addition, each holding member 151 of the screw holding mechanism 150 rises together with the second rotating member 130 while holding any one screw B in the second storage unit 102. As a result, only one operation of the first rotating member 120 by the operator's finger H is operated to hold any one screw B by the permanent magnet 152 of each holding member 151 and take it out from the second storage unit 101. Can do. In this case, by setting the number of holding members 151 according to the required number of screws B, it becomes possible to take out the required number of screws B from the second storage unit 102 without excess or deficiency. Therefore, the worker can take out one bag A and four screws B at hand and quickly pack the bag even when wearing protective gloves to prevent the screws B from being damaged. become. As a result, one bag A can be reliably taken out, and there is no need to retake, and it is easy to visually recognize that there are four screws B, and there is no need to recount or remove them. The required work time can be improved from, for example, 15 seconds to 7 seconds.

  According to the take-out device 100 configured as described above, when the first rotating member 120 rotates to the use position, the uppermost bag A in the first storage unit 101 is held by the bag holding mechanism 140. Thereafter, when the first rotating member 120 returns from the use position to the initial position, the bag A held by the bag holding mechanism 140 is taken out from the first storage unit 101. When the second rotating member 130 is rotated to the use position in conjunction with the rotation of the first rotating member 120, the four screws B in the second storage unit 102 are held by the screw holding mechanism 150. Thereafter, when the second rotating member 130 returns from the use position to the initial position, the four screws B held by the screw holding mechanism 150 are taken out from the second storage unit 102. And in this taking-out apparatus 100, these 2 taking-out operation | movement (operation which takes out one bag A and four screws B which are going to be accommodated in the bag A) is made into the 1st rotation member by an operator's finger. The operation can be performed simultaneously by only one action of 120, which is efficient. Further, the take-out device 100 does not require an electric mechanism, an electric circuit, or sensors. As a result, one bag A and four screws B can be efficiently taken out from the storage units 101 and 102 with a simple structure.

  Further, the take-out device 100 having the above-described configuration has an advantage that it is inexpensive and has few failures because it does not require electrical control. Further, according to the take-out device 100, the structure for holding the first rotating member 120 in the initial position together with the second rotating member 130 can be simplified using the weight 132 of the second rotating member 130. Can do.

  Further, according to the take-out device 100 configured as described above, when there is a height difference between the position of the first storage unit 101 and the position of the second storage unit 102, the relative positions of the support shaft 111 and the support shaft 112 in the support column 110. It can be dealt with by selecting the appropriate Seki.

  The present invention is not limited to the above exemplary embodiment, and various applications and modifications are possible. For example, each of the following embodiments to which the above embodiment is applied can be implemented.

  In the take-out device 100 of the above-described embodiment, when the pushing operation of the first rotating member 120 is released, the weight of the weight 132 is used to move both the first rotating member 120 and the second rotating member 130 to the initial position. In the present invention, an elastic member such as a spring that elastically biases the second rotating member 130 toward the initial position can be used instead of or in addition to the weight 132.

  In the screw holding mechanism 150 of the above-described embodiment, the holding member 151 configured so that the permanent magnet 152 can move on the bottom of the cylinder has been described, but any one screw B is reliably held by the magnetic force of the permanent magnet 152. When the effect is obtained, a structure in which the permanent magnet 152 is fixed to the holding member 151 can be employed.

  In the screw holding mechanism 150 of the above-described embodiment, the case has been described in which the screw B is held by using the magnetic force of the permanent magnet 152, but in the present invention, holding force other than the magnetic force of the permanent magnet, for example, an electromagnet It is also possible to adopt a structure for holding the screw B by utilizing the magnetic force of this, the adhesive force by the adhesive, and the like.

  In the above-described embodiment, the metal screw B made of a magnetic material is described as an example of an object to be stored in the storage bag. However, in the present invention, the object is held using the magnetic force of a permanent magnet. In this case, instead of the metal screw B made of a magnetic material, a small industrial product including a magnetic material, such as a screw, bolt, washer, nut, nail, pin, or the like, can be used.
