Since the standing portion 123 is inclined at an angle of less than 90 ° with respect to the installation surface 1 b (that is, the horizontal direction) of the article storage device 1, the pressing plate member 129 is also relative to the installation surface 1 b of the article storage device 1. Inclined. In other words, the standing portion 123 and the pressing plate member 129 are inclined at less than 90 ° with respect to the vertically downward direction. The guide plate 121 is provided on the front portion in the front-rear direction (the front side surface in the bag stacking direction) of the standing portion 123. The guide plate 121 is guided to the front surface 123a of the standing portion 123 so that the bag stacking direction and / or the width direction of the guide plate 121 coincide with the bag stacking direction and / or the width direction of the standing portion 123, respectively. It is provided so that the back surface of the plate 121 is disposed. Therefore, the guide plate 121 is inclined with respect to the horizontal direction or the vertical direction.

  The guide plate 121 may be provided in a manner that is detachable from the standing portion 123. In this case, the attachment portion 13 (L-shaped member) is, for example, the front surface of the standing portion 123 so as to be erected toward the front in the surface vertical direction (the front side in the bag stacking direction) of the front surface 123a of the standing portion 123. 123a. Two attachment holes 121b are provided in the vicinity of the end 121c of the center piece 124 of the guide plate 121 on the bag height direction bag mouth side. The guide plate 121 is attached so that the attachment portion 13 (L-shaped member) is passed through the two attachment holes 121b. And when removing the guide plate 121 from the standing part 123, the attachment hole 121b is removed from the attachment part 13 (L-shaped member).

  When the bag bundle 90 is held by the bag holding portion 11 as described above, the bag bundle 90 is held so as to have a predetermined inclination angle θ with respect to the installation surface 1b of the article storage device 1.

<1-2-2. About bag opening>
The bag opening portion 15 widens the bag mouth 91 d of the bag 91 disposed at the top in the stacking direction of the bag bundle 90 held by the bag holding portion 11. The bag opening part 15 is provided with the fixed axis | shaft 151, the expansion-contraction arm 160, and the front-end | tip arm 155 at least, for example.

  The fixed shaft 151 is provided on the housing 152, for example. The telescopic arm 160 and the tip arm 155 are held by the casing 152 through the fixed shaft 151. The fixed shaft 151 is disposed in the housing 152 at a position facing the guide plate 121 in the bag holding unit 11. The fixed shaft 151 extends in the width direction of the guide plate 121 (the width direction of the bag bundle 90).

  The telescopic arm 160 is pivotally attached to the fixed shaft 151 so that its own width direction and the direction in which the fixed shaft 151 extends coincide. The telescopic arm 160 is held in such a manner that it extends in the height direction of the housing 152 as shown in FIG. The telescopic arm 160 is a linear distance directly connecting the intermediate portion 160a of the telescopic arm 160 (the portion that is fixed to the fixed shaft 151) and the other end 160b of the telescopic arm 160 (hereinafter, this linear distance is referred to as the telescopic arm straight line). It has a telescopic mechanism that can expand and contract.

  The extension mechanism in the extension arm 160 is assumed to be configured by the lever arm 153 and the intermediate arm 154 as an example, but is not limited thereto, and may be configured by more arms.

  The lever arm 153 is pivotally attached to the casing 152 at an intermediate portion of the lever arm 153 via a fixed shaft 151 extending in the width direction of the lever arm 153. That is, the lever arm 153 is held by the housing 152 in a state where the lever arm 153 can rotate about the fixed shaft 151 as a center point. In a state where no force is applied, the lever arm 153 is held in such a manner as to extend in the height direction of the housing 152 as shown in FIG.

  When the lever arm 153 is tilted clockwise (in the direction of arrow A) by a predetermined angle with the fixed shaft 151 as a center point, the intermediate arm 154 and the tip arm 155 are formed on the guide plate 121 with the fixed shaft 151 as the center. Turn clockwise (arrow B direction).

  One end of the intermediate arm 154 is pivotally attached to one end of the lever arm 153 via the shaft 156. The shaft 156 extends in the width direction of the guide plate 121 (the width direction of the bag bundle). Such an intermediate arm 154 can rotate around a shaft 156. The other end of the intermediate arm 154 is pivotally attached to one end of the distal arm 155 via a shaft 157 and a return spring 158. The shaft 157 extends in the width direction of the guide plate 121 (the width direction of the bag bundle). Such a tip arm 155 can rotate around a shaft 157. The return spring 158 is an elastic spring member that generates a rotational force that restores the length direction of the tip arm 155 to coincide with the length direction of the intermediate arm 154 when the tip arm 155 is rotated.

  Here, the operation of the bag opening portion 15 will be described with reference to FIG. Before operating the bag-opening portion 15, as shown in FIG. 5A, the posture in which the telescopic arm 160 (the lever arm 153 and the intermediate arm 154) and the tip arm 155 are substantially linear is maintained. Thus, the telescopic arm 160 (the lever arm 153 and the intermediate arm 154) and the tip arm 155 are held. The telescopic arm linear distance at this time is the distance L0.

  As shown in FIG. 5B, when the lever arm 153 is rotated clockwise (in the direction of the arrow C) around the fixed shaft 151, both the intermediate arm 154 and the tip arm 155 are in the bag height direction. Move to the side. It is assumed that the bag 91 in FIG. 5 is at the top of the bag bundle 90 in the stacking direction.

  As shown in FIG. 5C, when the lever arm 153 is further rotated with the fixed shaft 151 as the center point, the intermediate arm 154 rotates with its own weight under the shaft 156 as the center point. Accordingly, the lever arm 153 and the intermediate arm 154 are bent upward (in the bag height direction bag mouth side). At this time, the linear distance of the telescopic arm is the distance L1 (<L0). In the state shown in FIGS. 5B and 5C, the lever arm 153 and the intermediate arm 154 are bent upward so that the linear distance between the telescopic arms is shortened.

  As shown in FIG. 5D, as the lever arm 153 further rotates, the distal end arm 155 moves further upward (in the bag height direction bag mouth side) and contacts the contact surface 125. When the distal arm 155 contacts the contact surface 125, the distal arm 155 rotates about the shaft 157 and the entire surface of the distal arm 155 contacts the contact surface 125.

  The contact surface 125 is a surface closer to the bag mouth in the bag height direction than the bag mouth 91d. The contact surface 125 moves to the inside of the bag 91 via the bag mouth 91d when the tip arm 155 moves along the contact surface 125 in the height direction bag bottom direction. Any mode may be used as long as it is possible. Further, on the contact surface 125, for example, an extension piece 91c of the bag 91 is disposed, or a pressing plate member 129 (see FIG. 4) is disposed. In FIG. 5D, the tip arm 155 is in contact with a portion on the contact surface 125 where the extension piece 91c is disposed, but this is an example, and the present invention is not limited to this. It is a design matter that the tip arm 155 is first moved to contact with which part on the contact surface 125.

  The tip arm 155 may be moved directly to the bag mouth 91d without being brought into contact with the contact surface 125. In this case, for example, the tip arm 155 once contacts the inner surface of the back bag piece 91b inside the bag 91 and moves to the bag height direction bag bottom side.

  Next, when the lever arm 153 is released, the intermediate arm 154 and the tip arm 155 side are heavier with the fixed shaft 151 as a boundary, and therefore, as shown in FIG. The lever arm 153 rotates in the direction of arrow D), and the tip arm 155 contacts the contact surface 125 (the front surface of the extension piece 91c) and travels along the bag height direction along the contact surface 125 (the front surface of the extension piece 91c). Move to the bottom of the bag. In the process, as shown in FIG. 5E, the tip arm 155 enters the inside of the bag 91 via the bag port 91d.

  On the other hand, the lever arm 153 and the intermediate arm 154 expand and contract the telescopic arm linear distance according to the reaction force that the tip arm 155 receives from the contact surface 125 (the front surface of the extension piece 91c). Then, as the lever arm 153 rotates, the intermediate arm 154 enters the interior of the bag 91 via the bag port 91d together with the tip arm 155 as shown in FIG.

  The lever arm 153 and the intermediate arm 154 operate so as to rotate about the shaft 156 and extend the linear distance of the telescopic arm as it enters the inner part of the bag 91. At the same time, as the lever arm 153 rotates away from the bag 91, the distal arm 155 gradually turns away from the inner side of the back bag piece 91b around the shaft 157 while moving away from the bag 91. Move to. Further, as the lever arm 153 rotates away from the bag 91, the intermediate arm 154 also moves away from the bag 91.

  By the operation of the intermediate arm 154 and the tip arm 155 as described above, the front bag piece 91a is pulled from the inner side of the bag 91 in the direction in which the bag mouth 91d spreads. Finally, the lever arm 153, the intermediate arm 154, and the tip arm 155 operate so as to return to the posture (initial state) of a substantially straight line as shown in FIG. 5 (f). To do. As a result, the bag mouth 91d is in a widely expanded state.

  Since the conventional bag opening arm hooks the tip near the bag mouth 91d to widen the bag mouth 91d, the force applied to the bag 91 when the bag mouth 91d is widened is large only near the bag mouth 91d. Thereby, the force applied to the separation line 91e of the bag 91 is increased, and the bag 91 is easily cut and separated from the separation line 91e in the process of expanding the bag 91. According to the telescopic arm 160 as described above, the distal arm 155 extends as it enters the interior of the bag 91, and as a result, the distal arm 155 and a part of the telescopic arm 160 (intermediate arm 154) The bag mouth 91d is widened in a state where it has entered deep inside. For this reason, if it is the said bag opening part 15, the force applied to the bag 91 when opening the bag opening 91d can be disperse | distributed to the whole bag 91, and the force applied to the separation line 91e of the bag 91 can be reduced. Thereby, it is possible to prevent the bag 91 from being cut and separated from the separation line 91e in the process of expanding the bag mouth 91d.

  Further, since the conventional bag opening arm has a predetermined trajectory of rotation, it is necessary to open the bag 91 with the bag on the top surface of the bag bundle 90 set on the trajectory. For this reason, when the bags 91 of the bag bundle 90 are cut and separated one after another and become an embodiment as shown in FIG. 2C, the bag bundle 90 is pushed from the back to determine the top bag of the bag bundle 90. It was set in the position. On the other hand, in the case of the bag opening portion 15, since the telescopic arm 160 is extended by that much even if the top surface of the bag bundle 90 is retracted, the above problems can be avoided.

  Note that the intermediate arm 154 and the tip arm 155 are in a posture (initial state) in which the lever arm 153, the intermediate arm 154, and the tip arm 155 shown in FIGS. 5A and 5F are substantially linear. ), The front bag piece 91a of the bag 91 is pulled toward the front side so that the bag 91 is adjusted to have a force that does not cut or separate from the bag bundle 90.

  The above two effects are common to other embodiments described below.

<1-3. Article conveyance path>
The article conveyance path 17 will be described with reference to FIG. In the article storage device 1, when an article is inserted from the article insertion opening 16, the article moves through the article conveyance path 17 and finally arrives at a base 122 as an end area. Therefore, the article conveyance path 17 in the article accommodation apparatus 1 is formed by the pressing plate member 129, the guide portion 12, and the base 122. In the article accommodating apparatus 1, the pressing plate member 129 is inclined by the inclination angle θ with respect to the installation surface 1 b (that is, the horizontal direction) of the article accommodating apparatus 1. In other words, it is inclined by (90 ° −θ) with respect to the vertically downward direction. In addition, the guide unit 12 is inclined by an inclination angle θ with respect to the installation surface 1 b of the article storage device 1. The base 122 is a flat member that is parallel to the installation surface 1 b of the article storage device 1. As a result, the article conveyance path 17 has, at least in part, an inclined path 17k having an angle of less than 90 ° with respect to the vertical downward direction.

  Further, the bag opening portion 15 is disposed at a position corresponding to the top side of the article transport path 17 in the bag stacking direction, and the bag bundle 90 and the guide section 12 are positioned at a position corresponding to the rear end side of the article transport path 17 in the bag stacking direction. Arranged. Therefore, the inclined path 17k is formed in such a manner that it is sandwiched between the bag opening portion 15, the bag bundle 90, and the guide portion 12 in the bag stacking direction. When the article storage device 1 is installed on the installation surface 1b, the bag opening portion 15 is disposed on the upper side in the vertical direction with respect to the ramp 17k, and the bag bundle 90 and the guide portion 12 are disposed on the lower side in the vertical direction.

  The article 80 thrown in through the article throwing opening 16 arrives at the base 122 as an end area through the ramp 17k. For this reason, when the article 80 passes through the ramp 17k, its own weight is dispersed in the horizontal direction, so that the falling speed is reduced and it is difficult to be damaged in the process of arriving at the base 122 as the termination region. Or, the packed contents are less likely to move in one direction.

<1-4. Article accommodation operation>
Next, the article accommodation operation will be described with reference to FIG. As shown in FIG. 6A, when the bag opening portion 15 is operated to open the bag 91, the article insertion opening 16 is provided to be disposed on the bag height direction bag mouth side of the bag mouth 91d. When the article 80 is thrown from the article throwing opening 16, the thrown article 80 has a pressing plate member 129 and a guide plate 121 constituting the article transport path 17 as shown in FIGS. 6A and 6B. It passes through and is accommodated in the bag 91.

  At this time, as shown in FIGS. 6A and 6B, the article 80 rolls or slides on an inclined path 17k that constitutes the article conveying path 17, so The movement speed is reduced by friction. Thereby, the impact which the article | item 80 collides with a predetermined location and can receive can be reduced.

  Also, since the article moves on the ramp 17k, unlike the conventional case in which the article is dropped from the vertical direction, in the case of a side dish in which the article is packed, the side dish is transported so as not to approach one side of the pack. be able to. In order to prevent the side dish from approaching one side of the pack, it is preferable to reduce the inclination angle θ with the installation surface 1 b of the article storage device 1. The size of the inclination angle with respect to the installation surface 1b of the article accommodating device 1 varies depending on the type of the article to be packed in the article accommodating device 1, and in the present invention, depending on various factors. Includes all determined tilt angles.

  At this time, the bag 91 is forced downward from the article 80. Due to this force, the bag 91 is cut and separated from the bag bundle 90 and dropped, as shown in FIG. At this time, the movement speed of the article 80 is reduced by the cutting / separating operation of the bag 91 from the bag bundle 90. This operation also contributes to protecting the article 80. In the case where the bag 91 is not naturally cut by the weight of the article 80, the operator may grasp the bag 90 by hand through the opening 77 and take it out.

  When the bag 91 is detached, as shown in FIG. 6D, the lever arm 153, the intermediate arm 154, and the tip arm 155 are further rotated, and the lever arm 153, the intermediate arm 154, and the tip arm are rotated. The posture returns to the posture (initial posture) in which 155 is substantially linear.

  Then, as described with reference to FIG. 5, the lever arm 153 is rotated again to open the bag 91, and the article 80 is loaded from the article loading opening 16. By repeating the above, the bagging operation of the article 80 is facilitated.

  Moreover, since the article conveyance path 17 has the inclined path 17k, for example, in the case of the spherical article 80, the article can be moved by rolling on the inclined path 17k, or in the case of the non-spherical article 80, the article can be moved. For this reason, since the inclined path 17k can receive a part of the weight of the article 80, the moving speed of the article 80 is reduced. Thereby, the impact when the article 80 stops in the final region can be reduced.

  Moreover, when the bag bundle 90 attached to the article accommodating apparatus 1 is configured by the bag 99 shown in FIG. 2D instead of the bag 91, the article accommodating operation is as shown in FIGS. 6C and 6D. It stops at FIG. 6B. That is, the bag 99 is not cut or separated from the bag bundle 90 by the collision force due to the movement of the article 80, and the article 80 is accommodated in the bag 99 while the bag 99 is coupled to the bag bundle 90. In this case, after confirming that the desired article 80 is accommodated in the bag 99, the bag 99 accommodating the article 80 is pulled by hand or the like to be cut and separated from the bag bundle 90. Such an embodiment is also included in the scope of the present invention.

  When the bag 99 containing the article 80 is pulled by hand or the like to be cut and separated from the bag bundle 90, the bag 99 cannot be pulled by the hand or the like if the article storage device 1 is configured to cover the periphery of the bag 99. . In order to secure a portion where the bag 99 is pulled by hand or the like, it is preferable to provide an opening 77 so as to open at least the outer peripheral peripheral region of the bag 99 to the outside in the direction perpendicular to the surface of the bag 99. Since the periphery of the bag 99 containing the article 80 is opened by the opening 77, the operator can easily grasp and remove the bag by hand.

<2. Second Embodiment>
Next, an article storage device 2 according to another embodiment of the present invention will be described with reference to FIG. For example, as shown in FIG. 7A, the article storage device 2 is provided with a stopper 18 in the article conveyance path 17.

  As illustrated in FIG. 7A, the stopper 18 is provided on the downstream side of the position where the bag 91 is disposed in the article conveyance path 17 (inclined surface). The stopper 18 can be engaged with the article 80 after being accommodated in the bag 99 to stop the movement of the article 80 or change the moving direction.

  Further, the stopper 18 is disposed so as to be reciprocally movable along the article conveyance path, and the article conveyance path 17 that the article 80 adds to the bag 91 when the article 18 is accommodated in the bag 91. An urging portion that absorbs force in a direction along the (slope 17k) may be provided. As such an urging portion, as shown in FIG. 7B, for example, one formed by an elastic body 18a such as a spring can be cited. According to the elastic body 18 a such as a spring, the stopper 18 can be urged in a direction opposite to the weight direction of the article 80. As a result, when the article 80 falls due to its own weight, the stopper 18 engaged with the article 80 can follow and move together with the article 80, and can apply a force in the opposite direction to the article 80. It can be stopped smoothly.

  The standby position of the stopper 18 is that when the article 80 is accommodated in the bag 91, the article 80 adds its own weight to the bag 91, and the bag 91 has the bag bundle 90 or the guide plate 121 (bag holding unit 11. The stopper 18 may engage with the article 80 to stop the movement of the article before it is separated from (). On the other hand, the article 80 may be received by the stopper 18 after the bag 91 is bundled 90 by the weight of the article 80. This is appropriately determined based on various factors such as the mass of the article 80, the distance from the article insertion opening 16 to the bag 91, and the strength of the separation line 91e in the bag 91.

<3. Third Embodiment>
Next, with reference to FIG. 8, an article storage device 3 according to another embodiment of the present invention will be described. The article storage device 3 is mainly used to pack packed goods such as packed side dishes. That is, the article storage device 3 is mainly intended for a thin three-dimensional shape.

  The difference between the article storage device 3 and the article storage device 1 is the shape of the article insertion opening 16a. In the article storage device 3, the shape of the article insertion opening 16a is substantially rectangular so that a three-dimensional shape having a small thickness can be easily put in. The article input opening 16a will be further described with reference to FIG. As shown in the plan view of the article storage device 3 in FIG. 9, the article insertion opening 16 a has both ends in the bag width direction on the ceiling surface of the casing 152 so that packed items such as side dishes can be easily introduced. It extends as wide as possible toward the side. In other words, the length of the article insertion opening 16a in the bag width direction may be made as long as possible in the casing 152 so as to be able to deal with a wide packed article.

  Further, the length of the article input opening 16a in the bag stacking direction does not need to be so long according to the target article. For example, when the length of the bag 91 in the bag width direction of the bag 91 is W, the length of the article insertion opening 16a is preferably 1 / 2W or less, more preferably 1 / W. The length is preferably 3 W or less. On the other hand, the length of the article input opening 16a in the bag width direction is set to 2/3 W or more, more preferably 3/4 W or more, and further preferably 4/5 W or more. Further, the width of the bag 91 suitable for such a configuration is 10 cm or more, desirably 15 cm or more, and more desirably 20 cm or more.

  In addition, as described above, since the article storage device 3 mainly targets the packed goods stored in the bag 91 to be thin, the length of the entire article storage device 3 in the bag stacking direction is shortened. Can do. Thereby, the article accommodation apparatus 3 can make the whole apparatus compact, and can be used in various places.

  Returning to FIG. In the article storage device 3, the article setting member 19 is provided on the bag height direction bag mouth side of the article insertion opening 16a. The article setting member 19 is a table on which the packed article is placed before the packed article is put into the article insertion opening 16a. The placement surface 19a of the article setting member 19 is a conveyance extension surface obtained by extending the conveyance surface 17b near the article insertion opening 16a in the article conveyance path 17 to the bag height direction bag mouth side. Moreover, since this mounting surface 19a is open, the article can be easily mounted.

  When a packed article is suddenly inserted into the conveying surface 17b of the article conveying path 17 through the article input opening 16a, it is assumed that it is difficult to insert the packed article depending on the size of the packed article. In such a case, if the article setting member 19 is present, the placement surface 19a is exposed to the surroundings. Therefore, after placing the packed article on the placement surface 19a, the user places the packed article. The packed article can be easily inserted into the conveyance surface 17b of the article conveyance path 17 through the article insertion opening 16a by simply pushing the placement surface 19a toward the article insertion opening 16a.

  In general, there are a considerable number of packed articles having a long length in the bag width direction. Therefore, in order to accommodate the pack-packed article having a long length in the bag width direction in the bag 91, the bag port 91d can be spread not only in the vicinity of the bag width direction center of the bag 91 but also at both ends in the bag width direction. preferable. For this reason, it is preferable that the tip arm 155a in the article storage device 3 is as long as possible in the bag width direction. This is because the distal end arm 155a can expand the bag opening 91d as much as possible across both ends in the bag width direction. For example, as shown in FIG. 9B, the length (width) of the distal arm 155a corresponding to the bag width direction is 1/3 W or more when the length of the bag 91 in the bag width direction is W. Preferably, it is set to 1/2 W or more, and more desirably 2/3 W or more.

<3-1. Article accommodation operation>
Next, the article accommodation operation in the article accommodation apparatus 3 will be described with reference to FIG. First, as shown in FIG. 10A, after the bag opening portion 15 is operated to open the bag 91, the packed article 80 a is placed on the placement surface 19 a of the article setting member 19. Then, the packed article 80 a is pushed toward the article conveyance path 17.

  When the packed article 80a is pushed from the above state, it is accommodated in the bag 91 along the conveyance surface 17b of the article conveyance path 17 via the article insertion opening 16a as shown in FIG. When the packed article 80a collides with the bag bottom 91h of the bag 91, the bag 91 is cut and separated from the separation line 91e.

  As shown in FIG. 10C, the bag 91 in which the packed product 80 a is accommodated moves further along the transport surface 17 b of the product transport path 17 to the downstream side of the product transport path 17. Then, as shown in FIG. 10D, the bag 91 in which the packed product 80a is accommodated finally arrives at the base 122, which is an end area, and stops. Note that a mat formed of a material having a high friction coefficient may be provided on the surface of the base 122 in order to reliably stop the bag 91 in which the packed articles 80a are stored on the base 122. Examples of the material having a high coefficient of friction include a material such as rubber, but the material is not limited to this, and other known materials having a high coefficient of friction may be used.

<4. Fourth Embodiment>
Next, an article storage device 4 according to another embodiment of the present invention will be described with reference to FIG. The article accommodating device 4 is different from the article conveying path 17 in the article accommodating device 1 in its form. The article conveyance path 17 in the article accommodation apparatus 1 is formed by an inclined surface that is inclined by an inclination angle θ with respect to the installation surface 1 b of the article accommodation apparatus 1. On the other hand, the article conveyance path 17 in the article accommodation apparatus 4 receives the impact force of the article conveyance path 41 perpendicular to the installation surface 4 a of the article accommodation apparatus 4 and the article 80 moved from the article conveyance path 41. It is formed by an inclined path 42 formed by a rotating inclined plate 43 that moves. The inclined path 42 is configured to be inclined with respect to the vertical direction.

  When the article transport path 41 is based on the installation surface 4 a of the article storage device 4, a standing portion 423 corresponding to the standing portion 123 in the article storage device 1 is erected substantially perpendicular to the installation surface 4 a. Is. That is, the standing portion 423 in the article storage device 4 is erected in the vertical direction with respect to the installation surface 4a of the article storage device 4, and is parallel to the vertical direction (not inclined with respect to the vertical direction).

  Further, in the guide plate 421 in the article storage device 4, the bag stacking direction and / or the width direction of the guide plate 421 coincide with the bag stacking direction and / or the width direction of the standing portion 423, respectively. Therefore, the guide plate 421 in the article storage device 4 is along the vertical direction.

  As shown in FIG. 11, the surface of the rotating inclined plate 43 has a rocking end side of the plate-like member in the thickness direction of the plate (the bag mouth side in the bag height direction ( It is formed to be convex in the upward direction in FIG. That is, the rotating inclined plate 43 is formed such that the swing end of the plate-like member is curved toward the thickness direction of the plate-like member.

  As a result, the rotating inclined plate 43 is divided into a flat plate portion 43a and a stopper portion 43b. The flat plate portion 43a is formed of a substantially flat plate. The stopper portion 43b is a plate-like member that stands in the out-of-plane direction (bag height direction bag mouth side) of the flat plate portion 43a on the swing end side of the flat plate portion 43a. As will be described later, the stopper portion 43b serves as a stopper that restricts the movement of the article. The flat plate portion 43 a forms the inclined path 42.

  As shown in FIG. 12, the rotation tilt plate 43 is provided with a rotation mechanism 44. The rotation mechanism 44 rotates the rotation inclined plate 43 in a direction to release the force according to the force applied when the article thrown from the article throwing opening 16 is placed on the turning mechanism 44. The rotation mechanism 44 includes a spring member 45, a shaft 46, a spring rotation limiting member 48 a, a member support portion 48 b, a support position adjustment portion 48 c, and a hinge portion 49.

  As shown in FIG. 12A, the spring member 45 is disposed on the bottom surface side in the thickness direction of the rotating inclined plate 43 so that its axial direction coincides with the width direction of the rotating inclined plate 43. As the spring member 45, for example, a coil spring is assumed as shown in FIG. 12A, but is not limited thereto. The both ends of the spring member 45 may be any of a straight type, a one-step bending type, a two-step bending type, and a hook type that extend linearly from the coil spring winding portion. One end of the spring member 45 is in contact with the bottom surface of the rotation inclined plate 43 and the other end is in contact with the spring rotation limiting member 48a.

  As shown in FIG. 12 (a), the shaft 46 is fixed by standing portions 423, both ends of which are erected from both ends in the width direction of the rotating inclined plate 43. The shaft 46 is disposed so as to coincide with the central axis of the spring member 45.

  The spring rotation limiting member 48 a is in contact with the other end of the spring member 45 to limit the rotation of the spring member 45. As shown in FIG. 12A, the spring rotation restricting member 48 a is pivotally attached to the shaft 46 in such a manner that the spring rotation limiting member 48 a is suspended so as to be rotatable about the shaft 46. Further, as shown in FIG. 12B, the spring rotation limiting member 48a is supported by the member support portion 48b from the back side in the front-rear direction of the spring rotation limiting member 48a. Thereby, the spring rotation restricting member 48a can be rotated to the front side in the front-rear direction of the spring rotation restricting member 48a, but the rotation of the spring rotation restricting member 48a to the rear side in the front-rear direction is restricted. .

  As shown in FIG. 12B, the member support portion 48b is a member that is disposed on the rear side in the front-rear direction of the spring rotation limiting member 48a and extends in the front-rear direction of the spring rotation limit member 48a. The support position adjusting part 48c moves the member support part 48b in the front-rear direction of the spring rotation restricting member 48a. In other words, the support position adjustment unit 48c adjusts the position of the front end in the front-rear direction of the spring rotation limiting member 48a of the member support unit 48b, so that the rotation range of the spring rotation limiting member 48a toward the rear side in the front-rear direction. Adjust.

  As shown in FIG. 12 (b), the hinge portion 49 rotates about a hinge shaft 49 a provided at a position corresponding to the end (base end portion) on the rearmost side in the bag stacking direction of the rotation inclined plate 43. The inclined plate 43 is rotated. The hinge shaft 49a extends in the bag width direction. The end of the rotationally inclined plate 43 on the rearmost side in the bag stacking direction is pivotally attached to the hinge shaft 49a.

  Here, with reference to FIG. 13, the operation of the article storage device 4 will be described. When an article is loaded from the article loading opening 16 in a state where the bag opening 91 d is widened by the bag opening portion 15, the article 80 is vertically lowered along the article conveyance path 41 and is accommodated in the bag 91. Then, as shown in FIG. 13A, the article 80 falls on the rotating inclined plate 43 while being accommodated in the bag 91. As shown in FIG. 13 (b), the rotating inclined plate 43 rotates clockwise by the hinge portion 49 when it receives its own weight due to dropping from the article 80 accommodated in the bag 91.

  When the spring member 45 receives this rotation, the spring member 45 becomes an urging member and exerts a force (restoring force) in a direction to rotate counterclockwise with respect to the rotation inclined plate 43 by spring elasticity. Add. The rotating inclined plate 43 applies a restoring force in a direction opposite to its own weight to the article 80 while swinging in the same direction as the falling direction of the article 80 accommodated in the bag 91. Further, since the inclined plate 43 is gradually inclined with respect to the vertical direction, a force for moving the article 80 in the horizontal direction is applied.

  As a result, the article 80 accommodated in the bag 91 absorbs the impact at the time of engagement by the following operation of the rotating inclined plate 43.

  When the rotating inclined plate 43 is inclined as shown in FIG. 13C, the article 80 accommodated in the bag 91 moves downstream along the inclined path 42 constituted by the rotating inclined plate 43. . Finally, the article 80 accommodated in the bag 91 collides with the stopper portion 43b, and its movement is restricted and stops. When the movement of the article 80 is stopped, the urging force applied to the article 80 by the spring member 45 and the weight of the article 80 are in parallel. That is, the inclination angle (movement amount) of the rotating inclined plate 43 changes depending on the weight of the article 80. Therefore, the turning mechanism 44 and the turning inclined plate 43 can present an indicator of the weight of the article 80, as in the so-called weighing. For example, by installing a scale corresponding to the stop angle of the rotating inclined plate 43, the weight of the article 80 is measured, or it is screened to a desired standard size (for example, S / M / L for agricultural products). can do.

  As described above, the article storage device 4 does not have the inclined path that is inclined with respect to the installation surface 4a of the article storage device 4 before the article is loaded. However, the article storage device 4 has an inclined path 42 that is inclined with respect to the installation surface 4a of the article storage device 4 after the article 80 is loaded and the article is stored in the bag. By the inclined path 42, the article 80 accommodated in the bag 91 is moved toward the downstream side of the article transport path 17.

<5. Fifth Embodiment>
Next, an article storage device 5 according to another embodiment of the present invention will be described with reference to FIG. The article storage device 5 is obtained by changing the rotation mode of the rotation inclined plate 43 in the article storage device 4. That is, the rotation inclined plate 43 in the article storage device 4 rotates around the hinge shaft 49a extending in the bag width direction, while the rotation inclination plate 53 in the article storage device 5 is centered on the hinge shaft 59a extending in the bag stacking direction.

The hinge shaft 59a extends in the bag stacking direction. The end portion of the rotating inclined plate 53 in the bag width direction is pivotally attached to the hinge shaft 59a.

  Note that the rotation mechanism 54 and the rotation mechanism 44 are the same in operation, except that the direction of the rotation axis of the rotation inclined plate and the arrangement of each part associated therewith are different. Accordingly, FIGS. 12 and 13 showing the contents and operations of the rotation mechanism 44 can be used as plan views of the rotation mechanism 54 as viewed from the bag stacking direction. The moving mechanism 54 can be applied as appropriate.

  The article 80 is vertically lowered along the article conveyance path 51 and is stored in the bag 91. When the article accommodated in the bag 91 falls with respect to the rotating inclined plate 53, the rotating inclined plate 53 rotates in the direction depicted by the dotted line in FIG. 14 and is inclined with respect to the vertical direction. 52 is formed. As a result, the article 80 drops and stops along the inclined path 52 while moving in the width direction of the bag 91. The article storage device 5 having such an aspect is effective, for example, when workers work in a row in the bag width direction. That is, there are workers A and B lined up in a row in the bag width direction, the worker A puts the article into the article storage device 5, and the next worker B is sent out from the rotating inclined plate 53. This is effective when the article 80 is taken out and the bag 91 is sealed.
