  The guide portion 12 is engaged with the bag bundle 90 to guide the vicinity of both ends in the width direction of the bag bundle 90 so as to protrude toward the front side in the bag stacking direction as compared with the vicinity of the center in the width direction of the bag bundle 90. It is what has. The guide unit 12 includes, for example, a main body unit 120 and a guide plate 121.

  The guide plate 121 engages with the rearmost surface of the bag bundle 90 in the bag stacking direction, and guides the vicinity of both ends in the width direction of the bag bundle 90 to be convex as compared with the vicinity of the center in the width direction of the bag bundle 90. It has a rear guide surface 121a. Here, the guide plate 121 will be described with reference to FIG. For example, as shown in FIG. 3A, the guide plate 121 is moved forward in the front-rear direction of the plate member as it proceeds from the center piece 124 that forms the vicinity of the center of the plate member in the width direction to both ends of the plate member in the width direction. A plate-like member having a bent shape is assumed as an example, but the present invention is not limited to this, and other modes may be used.

  When attaching the bag bundle 90 to the guide plate 121, the rearmost tail surface in the bag stacking direction of the bag bundle 90 is engaged (contacted) with the rear guide surface 121 a corresponding to the front of the guide plate 121. When the bag bundle 90 is engaged (contacted) with the rear guide surface 121 a of the guide plate 121, the attachment portion 13 is passed through the two attachment holes 92 in the bag bundle 90. When attaching the bag bundle 90 to the guide plate 121, the bag bundle 90 is attached so that the height direction of the bag bundle 90 coincides with the height direction of the guide plate 121.

  As shown in FIG. 3A, the attachment portion 13 is, for example, in the front-rear direction of the rear-side guide surface 121a of the guide plate 121 in the vicinity of one end in the height direction of the center piece 124 (end portion on the bag mouth side at the bag mouth) It is assumed to be two L-shaped members that are erected toward the front (front in the direction perpendicular to the plane), but is not limited to this, and one or three or more L-shaped members, Other embodiments may be used. The attachment portion 13 having one or three or more L-shaped members corresponds to the bag 91 (bag bundle 90) having one or three or more attachment holes 92. Further, the attachment portion 13 is not limited to the L-shaped member, and for example, a rod body (for example, the long side portion of the L-shaped member) through which the attachment hole 92 of the bag 91 (bag bundle 90) can be inserted; It may be considered that the inserted bag 91 (bag bundle 90) includes a stopper (for example, a short side portion of the L-shaped member) that prevents the inserted bag 91 (bag bundle 90) from being detached from the rod. In this case, the stopper may be fixed to the end portion of the rod body or in the vicinity thereof, or may be configured to be movable in the length direction of the rod body along the rod body. The two L-shaped members (or rods) are erected on the front side in the front-rear direction (front side in the vertical direction) of the rear-side guide surface 121a while being separated by a predetermined distance in the width direction of the guide plate 121.

  If the bag bundle 90 is attached to the guide plate 121 according to the above, the rearmost guide surface 121a of the guide plate 121 is engaged with the rearmost surface in the bag stacking direction of the bag bundle 90 as shown in FIG. It becomes an aspect. Further, the height direction of the guide plate 121 coincides with the bag height direction. As a result, compared to the vicinity of the center in the width direction of the bag bundle 90, the vicinity of both ends in the width direction of the bag bundle 90 is guided so as to protrude toward the leading side in the bag stacking direction of the bag bundle 90.

  Note that the mounting portion 13 including the two L-shaped members is preferably provided near the center in the width direction of the guide plate 121 (for example, in the center piece 124). This is to make it easier to attach the bag bundle 90 to the guide plate 121. When the attachment portion 13 is provided near the center in the width direction of the guide plate 121, it may be difficult to make the vicinity of both ends of the bag bundle 90 along the guide plate 121. In that case, as shown in FIG. 3C, the bag bundle 90 is formed by using two sandwiching members 128 that sandwich the bag bundle leading end portion corresponding to the coupling piece 91g of the bag bundle 90 and the guide plate 121 in the stacking direction. The vicinity of both ends may be along the guide plate 121. Note that one or three or more clamping members 128 may be provided. Alternatively, the two L-shaped members may be removed and the bag bundle 90 may be held on the guide plate 121 using only the clamping member 128.

  In the present invention, the guide plate 121 is an example. For example, the guide plate 121 does not bend to both ends in the width direction of the plate-like member, but extends straight, or any other deformation such as bending or bending. A guide plate of the shape is also included in the present invention.

  Next, the main body 120 will be described with reference to FIGS. 1 and 4. As shown in FIG. 1, the main body 120 includes a base 122 and a standing part 123. When the bag 91 attached to the guide plate 121 is used as a reference, the base 122 is disposed on the bag bottom side in the bag height direction. The standing portion 123 is formed by, for example, a plate member having a predetermined shape. Then, when the bag 91 attached to the guide plate 121 is used as a reference, the standing portion 123 is erected from one end of the base 122 toward the bag height direction bag mouth side.

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. On the contact surface 125, for example, an extension piece 91c of the bag 91 is disposed, or a pressing 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 possible to appropriately change which part on the contact surface 125 the tip arm 155 is moved to contact first.

  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 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 mouth height side bag mouth side of the bag mouth 91d. . When the article 80 is thrown from the article throwing opening 16, the thrown article 80 is accommodated in the bag 91 as shown in FIG.

  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. Thereafter, as shown in FIG. 6D, the lever arm 153, the intermediate arm 154, and the tip arm 155 are rotated, and the lever arm 153, the intermediate arm 154, and the tip arm 155 are substantially straight. It returns to the posture of the aspect which became upper.

  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, 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 170 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 170, the operator can easily grasp and remove the bag by hand.

<1-4. Article measurement operation>
Next, with reference to FIG. 7, the operation | movement which measures the weight of the articles | goods 80 accommodated in the bag 91 is demonstrated. First, as shown in FIG. 7A, an article 80 (not shown) is thrown by an operator (not shown) from the article loading opening 16 into a bag 91 whose bag opening 91d is widened by a bag opening portion 15 (not shown). The The bag 91 receives a load on the bag bottom 91h by the article 80 to be charged, and is separated by a separation line 91e and dropped to the weight measuring unit 18, as shown in FIG. 7B. The weight measuring unit 18 measures the weight of the article 80 accommodated in the bag 91 that has dropped. Such a weight measuring unit 18 includes, for example, an article receiving unit 180 and a weight measuring mechanism 181.

  The article receiving portion 180 is a member that receives the article 80 accommodated in the bag 91. The article receiving portion 180 is disposed in the termination area of the article conveyance path 17. The weight measuring mechanism 181 measures the weight of the article 80 accommodated in the bag 91 based on the load received by the article receiving unit 180 from the article 80 accommodated in the bag 91. The weight measuring mechanism 181 includes, for example, a spring 182 that is connected to the bottom surface of the article receiving unit 180, and measures the weight using the spring 182. That is, the weight measuring unit 18 is configured only by a so-called upper disc spring. The spring 182 is an example, and other elastic bodies may be used. The weight measured by the weight measuring mechanism 181 is displayed on the weight display unit 183. The weight display unit 183 includes a scale board 184 and a pointer 185. A scale (not shown) on the scale plate 184 pointed to by the pointer 185 is a weight measured by the weight measuring mechanism 181.

  As described above, if the weight measuring unit 18 is provided in the termination region of the article conveyance path 17, the weight of the article 80 accommodated in the bag 91 separated from the bag bundle 90 can be measured immediately. Thereby, the operation | work which puts an article | item in a bag, and the operation | work which sorts the article | item 80 by weight can be performed only by throwing the article | item 80 into the bag opening 91d opened. Conventionally, for example, an operation of packing agricultural products into a bag and an operation of measuring the weight of agricultural products are substantially divided into two steps. According to the article storage device 1, when the article 80 is inserted, the article 80 can be packed in a bag, and at the same time, the weight of the article 80 can be measured and can be performed in one step. Even if the article 80 stored in the bag 91 falls, the impact of the drop is absorbed by the elastic force of the spring 182 of the weight measuring unit 18, so that the article 80 can be prevented from being damaged.

<2. Second Embodiment>
Next, an article storage device 2 according to another embodiment of the present invention will be described with reference to FIG. The article storage device 2 has substantially the same configuration as the article storage device 1, but the arrangement position of the weight measuring unit 18 is different. The weight measuring unit 18 in the article storage device 1 is held by the bag holding unit 11 and is positioned from the lower end position in the bag height direction of the bag 91 (bag bundle 90) in a state of extending straight along the article transport path 17. Is also arranged downstream of the article transport path 17. On the other hand, the weight measuring unit 18 in the article storage device 2 is held by the bag holding unit 11 and is located at the lower end in the bag height direction of the bag 91 (bag bundle 90) in a state of extending straight along the article transport path 17. It is arranged on the upstream side of the article conveyance path 17 rather than the position. Since the article storage device 2 has substantially the same configuration as the article storage device 1, the same reference numerals as those of the article storage device 1 are used for the respective parts.

  For this reason, when the bag 91 (bag bundle 90) is attached to the bag holding part 11, as shown in FIG. 8, a predetermined length part is weighted from the lower end part (bag bottom 91h) of the bag 91 (bag bundle 90). It is placed on the article receiver 180 in the measuring unit 18. That is, since the bag 91 (bag bundle 90) has a predetermined length portion on the article receiving portion 180 from its lower end (bag bottom 91h), at least the lower part of the bag 91 is bent, Even if the article 80 is accommodated in the bag 91, if the article 80 does not have a predetermined weight or more, no force is applied to the separation line 91e and the article 80 is not separated from the bag bundle 90. The predetermined length portion from the lower end portion of the bag 91 (bag bundle 90) is at least from the lower end portion (bag bottom 91h) of the bag 91 (bag bundle 90) to the bag height direction lower than the bag opening 91d. Refers to the part.

<2-1. Product weight measurement operation>
Next, with reference to FIG. 9, the operation | movement which measures the weight of the articles | goods accommodated in the bag 91 is demonstrated. In FIG. 9, for the sake of simplicity, the bag opening portion 15 and the like in the article storage device 2 are omitted for the sake of convenience. The bag 91 in a state where the bag opening 91d is unfolded by the bag opening portion 15 (not shown) is, as shown in FIG. 9A, a predetermined length from the lower end portion before the article receiving portion 180 receives the article 80. The portion 91j is in a state of being placed on the article receiving portion 180 in the weight measuring portion 18 and is bent.

  In this state, when the articles 80 are continuously fed from the article loading opening 16, as shown in FIG. 9B, the plurality of articles 80 are received by the article receiving portion 180, and the bags 91 are not separated and the articles 80 are gradually separated. Contain. The article 80 accommodated in the bag 91 is absorbed by the spring 182 connected to the article receiving portion 180 so as to absorb the impact caused by dropping, and the impact received by the article 80 can be reduced. When the number of articles 80 accommodated in the bags 91 increases, as shown in FIG. 9B, the spring 182 contracts due to the weight of the plurality of articles 80, and the height of the article receiving portion 180 in the bag height direction accordingly. It goes down.

  When the weight of the article 80 accommodated in the bag 91 reaches a predetermined weight, the spring 182 is further contracted by the weight, and accordingly the height of the article receiving portion 180 in the bag height direction is further lowered. Go down. At this time, the article receiving portion 180 is lowered to a position where it is separated from the bag 91. When the article receiving portion 180 and the bag 91 are separated, the separation line 91e of the bag 91 receives force due to the weight of the article 80 accommodated in the bag 91, and as shown in FIG. 9C, the separation line 91e. The portion of the bag 91 below the bag height direction is separated and falls to the article receiving portion 180.

  The weight of the article 80 from which the article receiver 180 and the bag 91 are separated can be changed by adjusting the length of the spring 182, the spring constant, and the like, for example.

  Further, instead of the bag 91 in the article storage device 2, a bag 99 that does not include the separation line 91e may be used.

  In the article storage device 1, whether or not the bag 91 is separated from the separation line 91e depends on the strength of the bag at the separation line 91e. Therefore, the article storage device 1 is suitable, for example, in such a mode that it is assumed that the bag 91 is separated from the separation line 91e when the article is loaded. As an example based on the above, for example, a case where a single agricultural product with a unit weight of A circle is packed and measured for pricing is assumed as an example.

  On the other hand, in the article storage device 2, whether the bag 91 is separated from the separation line 91e depends on the weight of the article 80 accommodated in the bag 91. Therefore, in the article storage device 2, for example, when the weight of the article accommodated in the bag 91 becomes a predetermined weight or more, the bag 91 is assumed to be separated from the separation line 91e. Is suitable. As an aspect premised on the above, for example, a product in which a plurality of agricultural products are packed by a specified weight is assumed as an example.

  In the article storage devices 1 and 2 in the first and second embodiments described above, when a predetermined amount of articles is put into the bag 91, the bag 91 is separated from the separation line 91e by its weight. However, the present invention is not limited to this. That is, it is not the weight of the article, but includes a case where the bag 91 is separated from the separation line 91e by pulling by hand and the bag 91 in which the contents are stored is placed on the article receiving unit 180.

<3. Third Embodiment>
Next, the article storage device 3 will be described with reference to FIG. Since the article storage device 3 has substantially the same configuration as the article storage devices 1 and 2, the same reference numerals as those of the article storage devices 1 and 2 are used for the respective parts. Unlike the article storage device 2, the article storage device 3 has a length L1 from the separation line 91e of the bag 91 to the surface of the article reception portion 180, even if the height of the article reception portion 180 is reduced. This is a configuration that does not exceed the length L2 from the separation line 91e to the bag bottom 91h. That is, the article storage device 3 is configured to maintain a state in which no force is applied to the separation line 91e even when the spring 182 is in the most contracted state.

  Therefore, in the article accommodation device 3, for example, when the weight of the article accommodated in the bag 91 reaches a predetermined weight, it is assumed that the bag 91 is manually separated from the separation line 91e. Suitable for Further, in the article storage device 3, since the bag 91 is manually separated from the separation line 91e, it may be replaced with the bag 99 without the separation line 91e, and such a thing is also included in the present invention.

  In the article storage devices 1 and 2 in the first embodiment and the second embodiment, when the article 80 is put into the bag 91, it is assumed that the bag 91 is separated from the separation line 91e by its weight. In such a configuration, when the article is a dish including soup or soup, if the bag 91 is separated by weight, they may be scattered outside the bag 91. For this reason, for example, when the article accommodated in the bag 91 is a dish or the like containing soup or soup, it is particularly preferable to use the article accommodation apparatus 3.

  In the above-described article storage devices 1 to 3, it is assumed that the weight measuring unit 18 is configured by, for example, a scale that expresses the weight numerically. Examples of the scale expressing the weight by numerical values include, for example, only an upper disc spring and an electronic balance, but are not limited thereto, and other scales 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 storage device 4 is different from the weight measuring unit 18 in the article storage device 1 in its form. The weight measuring unit 18 in the article storage device 1 is formed of only a so-called upper disc spring or an electronic balance. On the other hand, the weight measuring unit 41 in the article storage device 4 includes a scale 42, an article receiving part 43 that receives the article 80 that has moved from the article transport path 17, and a rotation inclination that rotates and tilts the article receiving part 43. And a mechanism 44. Since the article storage device 4 has substantially the same configuration as the article storage device 1 except for the weight measurement unit 41, the reference numerals of the parts other than the portion related to the weight measurement unit 41 are the same as those of the article storage device 1. The same symbols will be used.

  As shown in FIG. 11, the surface of the article receiving portion 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 (see FIG. 11 in the upward direction)). That is, the article receiving portion 43 is formed such that the rocking end of the plate member is curved in the thickness direction of the plate member.

  As a result, the article receiving portion 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.

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

  As shown in FIG. 12A, the spring member 45 is disposed on the bottom side in the thickness direction of the article receiving portion 43 so that its own axial direction coincides with the width direction of the article receiving portion 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 article receiving portion 43, and the other end is in contact with the spring rotation limiting member 48a.

  As shown in FIG. 12A, the shaft 46 is fixed by standing portions 423 whose both ends are erected from both ends in the width direction of the article receiving portion 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 has an article receiving portion centered on a hinge shaft 49 a provided at a position corresponding to the end (base end portion) of the article receiving portion 43 on the rearmost side in the bag stacking direction. 43 is rotated. The hinge shaft 49a extends in the bag width direction. The end of the article receiving portion 43 on the rearmost side in the bag stacking direction is pivotally attached to the hinge shaft 49a.

  Further, the scale member 42 includes a scale corresponding to the inclination angle of the article receiving portion 43. That is, the scale member 42 with which the inclination angle of the article receiving portion 43 can be visually recognized is constituted by a fan-shaped member with a scale attached to the surface as shown in FIG. The center of the member is disposed so as to coincide with the center of the hinge shaft 49a. The scale member 42 is not limited to a fan-shaped member having a scale on the surface, and any other scale member may be used as long as the scale is attached so that the inclination angle of the article receiving portion 43 can be visually recognized. It may be.

  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 17 and is stored in the bag 91. Then, as shown in FIG. 13A, the article 80 falls onto the article receiving portion 43 while being accommodated in the bag 91. As shown in FIG. 13 (b), the article receiving portion 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 applies a force (restoring force) in a direction to rotate counterclockwise with respect to the article receiving portion 43 by spring elasticity. . The article receiving portion 43 applies a restoring force in the direction opposite to its own weight to the article 80 while swinging in the same direction as the dropping direction of the article 80 accommodated in the bag 91. Furthermore, since the article receiving portion 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 an impact at the time of engagement by the following operation of the article receiving portion 43.

  When the article receiving portion 43 is inclined as shown in FIG. 13C, the article 80 accommodated in the bag 91 moves downstream along the inclined path constituted by the article receiving portion 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 article receiving portion 43 varies depending on the weight of the article 80. Accordingly, the turning and tilting mechanism 44 and the article receiving portion 43 can present an indicator of the weight of the article 80 in the same manner as a so-called weighing. By installing the scale member 42 corresponding to the stop angle of the article receiving portion 43 as in the article storage device 4, the article 80 is weighed or has a desired standard size (for example, SM, M · L) or the like. That is, when the weight of the article 80 is measured, a numerical value is assigned to the scale on the scale member 42. In addition, when sorting according to the standard size of the article 80, the scale in the scale member 42 is attached with a symbol or the like (S, M, L) indicating the standard size.

<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 article receiving portion 43 in the article storage device 4. That is, the article receiver 43 in the article storage device 4 rotates around the hinge shaft 49a extending in the bag width direction, while the article receiver 53 in the article storage device 5 rotates around the hinge shaft 59a extending in the bag stacking direction. Move. Since the article storage device 5 has substantially the same configuration as the article storage device 4 except for the rotation mode of the article receiving portion 53, the reference numerals of the respective portions other than the portion related to the rotation mode of the article receiving portion 53 are used. Uses the same reference numerals as the article storage device 4.

  The article receiving portion 53 is provided with a rotation tilt mechanism 54. The rotation tilt mechanism 54 rotates the article receiving portion 53 around an axis extending in the bag stacking direction.

  A hinge portion 59 is provided at a position corresponding to the end portion of the article receiving portion 53 in the bag width direction. As shown in FIG. 14, the hinge part 59 rotates the article receiving part 53 around a hinge shaft 59 a provided at a position corresponding to the end of the article receiving part 53 in the bag width direction. The hinge shaft 59a extends in the bag stacking direction. The end of the article receiving portion 53 in the bag width direction is pivotally attached to the hinge shaft 59a.

  The rotation tilt mechanism 54 and the rotation tilt mechanism 44 are the same in operation, except that the direction of the rotation axis of the article receiving portion and the arrangement of each portion associated therewith are different. Therefore, FIGS. 12 and 13 showing the contents and operations of the rotation tilt mechanism 44 can be used as plan views of the rotation tilt mechanism 54 viewed from the bag stacking direction. The description can be applied to the rotation tilt mechanism 54 as appropriate.

  The article 80 is vertically lowered along the article conveyance path 17 and is stored in the bag 91. When an article stored in the bag 91 falls with respect to the article receiving portion 53, the article receiving portion 53 rotates in a direction drawn by a dotted line in FIG. Form. 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 arranged in a row in the bag width direction, the worker A puts the article into the article accommodating device 5, and the next worker B is sent out from the article receiving unit 53. This is effective when 80 is taken out and the bag 91 is sealed.

<6. Sixth Embodiment>
Next, an article storage device 6 according to another embodiment of the present invention will be described with reference to FIG. The article accommodating device 6 mainly includes a bag opening mechanism 60 and an article conveying path 67 in which the bag opening mechanism 10 and the article conveying path 17 in the article accommodating apparatus 1 are inclined by a predetermined angle θ with respect to the installation surface. Other than that, it is the same as the article accommodation apparatus 1.

  The article conveyance path 67 will be described with reference to FIG. In the article storage device 6, when an article is inserted from the article insertion opening 66, the article moves through the article conveyance path 67 and finally arrives at a termination area (not shown). Therefore, the article conveyance path 67 in the article accommodation device 6 is formed by the pressing plate member 629, the guide portion 62, and a termination region (not shown).

  In the article storage device 6, the pressing plate member 629 is inclined by an inclination angle θ with respect to the installation surface 6 b of the article storage device 6 (that is, in the horizontal direction). In other words, it is inclined by (90 ° −θ) with respect to the vertically downward direction. In addition, the guide part 62 is inclined by an inclination angle θ with respect to the installation surface 6 b of the article storage device 6. Further, the termination region (not shown) may be constituted by a planar member parallel to the installation surface 6b of the article accommodating device 6, or may be constituted by a weight measuring unit (not shown). As a result, the article conveyance path 67 has at least a part of the inclined path 67k having an angle of less than 90 ° with respect to the vertical downward direction.

  Further, a bag opening portion 65 is disposed at a position corresponding to the top side of the article transport path 67 in the bag stacking direction, and a bag bundle 90 and a guide section 62 are disposed at a position corresponding to the rearmost side of the article transport path 67 in the bag stacking direction. Arranged. Therefore, the slope 67k is formed in such a manner as to be sandwiched between the bag opening portion 65, the bag bundle 90, and the guide portion 62 in the bag stacking direction. When the article storage device 6 is installed on the installation surface 6b, the bag opening portion 65 is disposed on the upper side in the vertical direction from the inclined path 67k, and the bag bundle 90 and the guide portion 62 are disposed on the lower side in the vertical direction.

  The article 80 that is thrown in through the article throwing opening 66 arrives at the final region (not shown) through the ramp 67k. For this reason, since the weight of the article 80 is dispersed in the horizontal direction when passing through the ramp 67k, the fall speed is reduced, and the article 80 is not easily scratched or packed in the process of arriving at the terminal area. The contents are difficult to move in one direction.

<7. Seventh Embodiment>
Next, with reference to FIG. 16, an article storage device 7 according to another embodiment of the present invention will be described. The article storage device 7 is mainly used for bagging packed goods such as packed side dishes. That is, the article storage device 7 is mainly intended for a three-dimensional shape having a small thickness.

  The article accommodating device 6 and the article accommodating device 7 have substantially the same structure. The difference between the article storage device 7 and the article storage device 6 is the shape of the article insertion opening 76a. In the article storage device 7, the shape of the article insertion opening 76 a is substantially rectangular so that a three-dimensional shape having a small thickness can be easily input. The article input opening 76a will be further described with reference to FIG. As shown in the plan view of the article storage device 7 in FIG. 17, the article insertion opening 76 a has both ends in the bag width direction on the ceiling surface of the casing 752 so that packed articles 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 76a in the bag width direction may be made as long as possible in the housing 752 so as to be able to deal with a wide packed article.

  Further, the length of the article insertion opening 76a 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 loading opening 76a 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 76a 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 7 mainly targets the packed goods stored in the bag 91 to be thin, the length of the entire article storage device 7 in the bag stacking direction is shortened. Can do. Thereby, the article accommodation apparatus 7 can make the whole apparatus compact, and can be used in various places.

<8. Eighth Embodiment>
Next, an article storage device 8 according to another embodiment of the present invention will be described with reference to FIG. The article storage device 8 has a weight measuring unit 88 disposed in the middle of an article conveyance path 87 corresponding to the inclined article conveyance path 77 in the article accommodation apparatus 7. That is, the weight measuring unit 88 is provided not in the termination region but in the guide unit 82. The weight measuring section 88 includes an article receiving section 85 that receives the article 80 that has moved from the article transport path 87, and a rotation tilt mechanism 86 that rotates and tilts the article receiving section 85.

  The article receiving part 85 in the weight measuring part 88 is held by, for example, the bag holding part 83 and is at the lower end in the bag height direction of the bag 91 (bag bundle 90) in a state of extending straight along the article conveying path 87. It is arranged upstream of the article conveyance path 87 rather than the position. This is because the bag 91 is not separated from the bag bundle 90 at an unintended timing due to the impact of the article 80. The article receiving portion 85 is disposed at an angle of, for example, approximately 90 ° with respect to the article conveyance path 87 in the initial state so as to prevent the article 80 accommodated in the bag 91 from proceeding.

  For this reason, when the bag 91 (bag bundle 90) is attached to the bag holding portion 83, as shown in FIG. 18A, a predetermined length portion from the lower end portion of the bag 91 (bag bundle 90) is the article receiving portion 85. On. That is, since the bag 91 (bag bundle 90) has a predetermined length portion on the article receiving portion 85 from its lower end, the bag 91 is bent and the article 80 is accommodated in the bag 91. However, it does not immediately separate from the bag bundle 90 due to the weight of the article 80.

  The rotation tilt mechanism 86 rotates the article receiving portion 85 according to the load that the article receiving portion 85 receives from the article 80. As shown in FIG. 18 (a), the article receiving portion 85 is rotated by being pushed by the article 80 accommodated in the bag 91 so that the article receiving portion 85 is brought into the bag 91 around a predetermined rotation fulcrum 86a. The thing which inclines toward the advancing direction of the articles | goods 80 accommodated is assumed. When the article receiving portion 85 is tilted toward the traveling direction of the article 80 accommodated in the bag 91, the article receiving portion 85 is finally positioned on the rear side in the bag stacking direction from the surface of the article conveying path 87. become. As a result, the article 80 accommodated in the bag 91 can travel toward the end region. Note that the final position of the article receiving portion 85 after tilting may protrude from the surface of the article transport path 87 as long as the article 80 accommodated in the bag 91 can travel toward the end region.

  As shown in FIG. 18B, the rotation tilt mechanism 86 advances along the article conveyance path 87 of the article 80 accommodated in the bag 91 as described above when the article 80 is not less than a predetermined weight. The article receiving portion 85 is rotated so as to allow the In that sense, the weight measuring unit 88 including the article receiving unit 85 and the rotation tilt mechanism 86 measures whether or not the article 80 has a predetermined weight or more. As a specific structure of the rotation tilt mechanism 86, for example, a hinge structure with a spring extending in the bag width direction is provided at the rotation fulcrum 86a of the article receiving portion 85, or the rotation tilt mechanism 44 in the article storage device 4 is employed. However, the present invention is not limited to these examples. Note that the spring-equipped hinge structure refers to a structure that returns to the initial posture of the hinge structure when a force is applied to the hinge structure using the restoring force of the spring.

  In FIG. 18, the article accommodating device 8 is based on the article accommodating device 7, but is not limited to this, and may be based on the article accommodating device 6. Moreover, the weight measurement part 88 is applicable also to what an article conveyance path follows a perpendicular direction like the article accommodation apparatuses 1-5.

<9. Ninth Embodiment>
Next, with reference to FIG. 19, an article storage device 9 according to another embodiment of the present invention will be described. In the article storage device 9, the same parts as those of the article storage device 1 will be described using the same reference numerals as those of the article storage device 1. Unlike the article storage apparatus 1, the article storage apparatus 9 uses only a spring 900 as a weight measurement unit. For example, as shown in FIG. 19A, the spring alone 900 is arranged such that a spring 901 built in itself is along the article conveyance path 17.

  Further, the weight display 903 of the spring alone 900 is visible through a window 902 provided in the housing 152, for example, as shown in FIG. The window 902 is an opening of the housing 152 formed within a range in which the weight display 903 of the spring 900 disposed inside the housing 152 is visible from the outside. If visible from the outside, the window 902 may be opened, or a transparent material such as a transparent film may be attached.

  The weight display 903 of the spring weight 900 may be displayed on a scale as shown in FIG. 19A, for example, or a display (not shown) may be provided and displayed numerically there. It may be done.

  Further, guide rails 904 are provided on both sides of the guide plate 121 so that the guide plate 121 can move in the direction along the article conveyance path 17. The tip member 905 of the spring 900 connected to the spring 901 is connected to the guide plate 121. Thus, when the spring 901 built in the spring 900 is expanded and contracted, the guide plate 121 is guided by the guide rail 904 and moves in the direction along the article conveyance path 17. In addition, the connection aspect of the front-end | tip member 905 and the guide plate 121 is not restricted to the aspect connected with one point as shown to Fig.19 (a), Other aspects including the aspect connected with several points | pieces It may be.

  When the loaded article 80 is received by the bag 91, the spring 901 extends to a position corresponding to the weight of the article 80 as shown in FIG. At the same time, the guide plate 121 moves vertically downward.

  When using the article storage device 9 as described above, first, an operator (not shown) puts the article 80 into the bag 91 while looking at the weight display 903 from the window 902, for example. The loading of the article 80 is continued until the weight display 903 displays a desired weight. When the weight display 903 displays a desired weight, an operator (not shown) stops the loading of the article 80, pulls the bag 91, and cuts it from the separation line 91e. Next, the bag mouth 91d of the bag 91 is opened at a bag opening portion (not shown), and the same process is repeated.

  The above-described springs 900 are only examples of springs, and the case where only the springs having other structures are used as the weight measuring unit is also included in the scope of the present invention. For example, a digital measuring device 920 shown in FIG. For example, as shown in FIG. 19C, the digital measuring instrument 920 includes an object holding unit 921, a load sensor 922, a calculation unit 923, a display unit 924, and a reset processing unit 925.

  The object holding unit 921 holds the bag holding unit 11 and the bag and contents 940. Specifically, the object holding unit 921 suspends and holds the bag holding unit 11 holding the bag and the contents 940.

  The load sensor 922 detects a load received through the object holding unit 921. An example of the load sensor 922 is a load cell. However, other types of load sensors may be used.

  The calculation unit 923 calculates the weight based on the detection result detected by the load sensor 922. The object of weight is the contents of the bag. Therefore, the load sensor 922 detects the load of the bag holding unit 11 and the bag and contents 940, and the calculation unit 923 calculates the value obtained by subtracting the weight of the bag holding unit 11 and the bag. The calculation result in the calculation unit 923 is displayed on the display unit 924.

  The reset processing unit 925 resets the calculation result of the calculation unit 923 to the initial state. When reset to the initial state, the calculation result of the calculation unit 923 is set to zero. The reset timing in the reset processing unit 925 is preferably when the bag opening unit 15 is operated so that the bag opening of the bag is widened. This is because the calculation result of the calculation unit 923 is set to 0 in a state where the contents are not accommodated in the bag, and the weight of only the contents can be measured.

  In addition, the target object holding | maintenance part 921 may have a mounting surface in which a bag and the content 940 are mounted. In this case, for example, a configuration in which a pressure sensor is used as the load sensor 922 and the load of the bag and the contents 940 is detected is assumed.

Further, at both ends of the support bar 913, rotation shafts 913a and 913b extending in the front-rear direction of the article storage device 100 (direction perpendicular to the paper surface of FIG. 20) are rotatably provided.

  The weight portion 914 and the guide plate support portion 915 are pivotally attached to the rotation shafts 913a and 913b, respectively. The weight portion 914 includes a suspension member 914a whose one end is pivotally attached to the rotation shaft 913a, and a weight 914b provided at the other end of the suspension member 914a. The other end of the suspension member 914a has a structure in which the weight 914b can be replaced.

  The guide plate support portion 915 includes a suspension member 915a whose one end is pivotally attached to the rotation shaft 913b, and a connection portion 915b provided at the other end of the suspension member 915a. The connecting portion 915b has a structure that can be connected to the guide plate 121.

  Further, guide rails 916 are provided on both sides of the guide plate 121 so that the guide plate 121 can move in the direction along the article conveyance path 17.

  In the article storage apparatus 100 as described above, before the bag 91 receives the article 80 to be put in, as shown in FIG. The support bar 913 is tilted by the balance mechanism 912 so as to be positioned.

  On the other hand, when the articles 80 are continuously charged and received by the bag 91, the support bar 913 gradually rotates so that the inclination with respect to the horizontal direction becomes small. The support bar 913 faces the horizontal direction at a position where the weight on the weight portion 914 side and the weight on the guide plate support portion 915 side are balanced.

  When using the article storage device 100 as described above, first, an operator (not shown) puts the article 80 into the bag 91 while looking at the inclination of the support rod 913, for example. When the support bar 913 comes to face in the horizontal direction, it is assumed that an article 80 having a desired weight has been put into the bag 91, and the operator (not shown) stops the putting of the article 80, The bag 91 is pulled and cut off from the separation line 91e. Next, the bag mouth 91d of the bag 91 is opened at a bag opening portion (not shown), and the same process is repeated.
