As a conventional unloading device for sequentially unloading flat plates such as packaging bags called pouches one by one, the unloading device in the form disclosed in Patent Document 1 below and Patent Document 2 below. The disclosed form of the unloading device can be mentioned.

The unloading device disclosed in Patent Document 1 below includes a transport conveyor that transports a large number of objects to be transported stacked and arranged by shifting them by a deviation dimension of, for example, about 8 to 10 mm in the transport direction, and a transport conveyor at the highest level and in the transport direction.

It is equipped with a carry-out means for carrying out downward from.

Japanese Patent No. 5897999 Japanese Unexamined Patent Publication No. 2015-221667

In the unloading device of the form disclosed in Patent Document 1, it is necessary to manually stack and arrange a large number of objects to be transported on the conveyor by shifting them by the dimensions in the transport direction, which is considerably complicated. There is a tendency that if a relatively large error occurs in the deviation dimension, it cannot be separated one by one and two or more objects to be transported are carried out at the same time. There is a problem that it is necessary to considerably increase the length of the conveyor in the transport direction in order to stack and arrange the objects to be transported.

On the other hand, in the unloading device of the form disclosed in Patent Document 2, if the number of objects to be transported to be laminated on the support means is increased, the weight of the entire objects to be transported increases, and therefore the weight of the objects to be transported is the lowest layer. The frictional resistance between the lower surface of the surface and the bottom wall of the support means increases, which makes it difficult to carry out the transported object through the carry-out opening, or two or more transported objects are carried out at the same time. There is a problem that it may end up.

In view of the above facts, the present inventors have previously described, in the specification and drawings of Japanese Patent Application No. 2016-21165, as a one-sided edge restricting member as a carry-out device for solving the above-mentioned problems existing in the conventional carry-out device. A large number of objects to be transported are placed upright in parallel along a predetermined transport path on the support means), and the most advanced objects to be transported are sequentially carried out and arranged in parallel according to the delivery of one or more objects to be transported. We have proposed a unique type of unloading device that can appropriately move a large number of transported objects to the downstream side in the transport direction (hereinafter referred to as "preceding unloading device"). This preceding unloading device is a transporting means in which a large number of flat plate-shaped objects to be transported are stacked and the edges of both ends and one side of the objects to be transported are regulated and forced toward the unloading end. A front end edge restricting means to which the edge is abutted, and a separate carrying means for separating the frontmost object to be transported from the front one end edge regulating means and separating it from the next object to be transported and carrying it out from the transport means. Equipped. The transport means includes a one-sided edge regulating member that regulates one side edge of the transported object, a one-ended edge regulating member that regulates one end edge of the transported object, and a other end edge regulating member that regulates the other end edge of the transported object. I'm out. The separate unloading means includes at least one suction tool that is selectively set to an operating state, and the suction tool is in a forward position that abuts on the front surface of the object to be transported at the front end and a retracted position that separates the device from the object to be transported at the front end. It can move forward and backward between the two, and can move back and forth in the extending direction of the object to be transported (that is, the direction from one end edge to the other end edge and the direction from the other end edge toward one end edge). When the frontmost object to be transported is separated and carried out, the suction tool is advanced to the forward position and the suction tool in the operating state sucks the front surface of the object to be transported. Next, the suction tool is moved toward the other end edge of the object to be transported, and the frontmost object to be transported is bent between the other end edge regulating member and the suction tool, whereby the frontmost object to be transported is displaced. It is separated from the next object to be transported, and then the suction tool is retracted to the retracted position and the frontmost object to be transported is carried out.

And Thus, the prior transportable detection device is not also satisfactory enough, a problem to be solved as follows. When handling objects with different dimensions, the position of the other edge restricting member with respect to the one end edge regulating member is changed according to the extending length of the transported object. It is necessary to adjust the dimensions between and, and each time a transported object having a different dimension is handled, a complicated adjustment operation is required. If the arrangement of the other end edge restricting member is omitted in order to avoid such an adjustment operation, according to the experience of the present inventors, it fails to separate the frontmost transported object from the next transported object. There is a tendency for two or more objects to be transported to be carried out at the same time.

The present invention has been made in view of the above facts, and its main technical problem is that even if the arrangement of the other end edge restricting member is omitted in order to avoid the above-mentioned complicated adjustment operation, the frontmost covered portion is covered. It is an object of the present invention to provide a new and improved unloading device capable of reliably separating and unloading a transported object from the next transported object.

The present inventors have continued diligent studies and experiments, and separated and carried out including at least two suction tools arranged at intervals in the direction from one side edge to the other side edge where the object to be transported is regulated. Means are arranged so that at least one of the two suction tools, which is far from the regulated one-sided edge of the object to be transported, is far from the regulated one-sided edge of the object to be transported and is regulated on one side. It is movable in the separation direction approaching the edge and in the opposite direction, and when the frontmost object to be transported is separated and carried out, the two suction tools are advanced to the forward position to move the front surface of the frontmost object to be transported. The suction tool is configured to be sucked, and then the suction tool far from the restricted one-sided edge of the object to be transported in the two suction tools is moved in the separation direction and the two suction tools are retracted to the retracted position. By doing so, it was found that the above-mentioned main technical problems can be achieved.

Further, a separate carrying-out means including a suction tool extending in a direction extending from one side edge of the object to be transported toward the other side edge is provided, and the suction tool is provided from one side edge of the object to be transported. When the far end is movable in the separation direction and the opposite direction away from the regulated one-end edge of the object to be transported and close to the regulated one-side edge, and the frontmost object to be transported is separated and carried out. The suction tool is also configured to be advanced to the advancing position to attract the front surface of the object to be transported at the foremost end, and then the suction tool is moved in the separation direction and retracted to the retracted position. We have found that the above major technical issues can be achieved.

Continuing the description with reference to FIGS. 2 to 4 together with FIG. 1, the first support member 8a is a rectangular plate-shaped member, and its four corners are supported by rod-shaped legs 16a. The first support member 8a as a whole is such that the one side edge 18 and the other side edge 20 extending in the longitudinal direction are both substantially horizontal and the one side edge 18 is lower than the other side edge 20. It is tilted at an tilt angle α with respect to the horizontal (see also FIG. 5). The tilt angle α is preferably 10 to 45 degrees, and is 20 degrees in the illustrated embodiment. The first support member 8a is provided with a one-side edge regulating member 22 on which a large number of flat plates to be transported are placed in a laminated state and regulates one side edge thereof, and the one-side edge regulating member 22 is provided with an upper side. A tilt regulation upper surface 24 that is inclined outward in the width direction (that is, from one side edge 18 toward the other side edge 20) is defined. The one-side edge restricting member 22 is defined with a transport path L in its longitudinal direction, that is, in the direction indicated by the arrow in FIGS. 2 and 3 (this is referred to as a transport direction, and hereinafter may be referred to as a front-rear direction). The transport path L is a path through which the object to be transported is transported as described later, and is horizontal and straight in the illustrated embodiment. As is clearly understood by referring to FIGS. 1 and 3, a plurality of grooves 26 extending linearly along the transport direction from the upstream end to the downstream end in the transport direction are formed in the one-side edge restricting member 22. Has been done. In the illustrated embodiment, three grooves 26 are formed, and the grooves 26 are represented by numbers 26a, b, and c, respectively. Each of the grooves 26 is parallel to each other and penetrates from the upper surface to the lower surface of the one-side edge regulating member 22. As is clearly understood by referring to FIG. 3, there are a plurality of small holes 28, which are circular through holes, at equal intervals along the transport direction between the grooves 26a and the grooves 26b in the width direction. In the illustrated embodiment, six are formed. Each of the small holes 28 has moved from the retracted position (states shown in FIGS. 1 to 4 (see particularly FIG. 3)) of the back plate 10 described later to the upstream side in the transport direction by X, which will be described later, when viewed in the transport direction. Starting from the position, they are sequentially formed at intervals of X toward the upstream side in the transport direction. If desired, the small holes 28 may be formed between the groove 26a and the groove 26b instead of, or together with, the groove 26a and the groove 26b.

The first support member 8a is a substantially flat rectangular flat plate, and includes a one-end edge regulating member 30 that regulates one-end edge of the transported object. The one-end edge regulating member 30 is an upstream end portion of the first support member 8a on the one side edge 18 side in a state of standing vertically upward from the upper surface of the first support member 8a along the transport direction. It is extended from to the downstream end. The one-end edge regulation member 30 is provided with an inclination regulation inner surface 32 that is inclined downward toward the inclination regulation upper surface 24 of the one-side edge regulation member 22, and the inclination regulation inner surface 32 and the inclination regulation upper surface 24 are perpendicular to each other. .. For this reason, the one-sided edge regulating member 30 and the one-sided edge regulating member 22 are also vertical (see also FIG. 5).

The front one-end edge restricting means 4 is arranged at the downstream end of the one-end edge regulating member 30 in the transport direction. In the illustrated embodiment, the front one-end edge regulating means 4 is fixed to the downstream end face in the transport direction of the one-end edge regulating member 30 and is perpendicular to the inclination regulating inner surface 32 toward the inside in the width direction (in other words, one side). It is a flat plate member having a rectangular cross section extending from the edge 18 toward the other side edge 20. As is clearly understood by reference to FIG. 5, the front end edge regulating means 4 has a trapezoidal shape that tapers as it is separated from the tilt regulation inner surface 32. Further, the front edge regulation means 4 is provided in the central portion as seen in the width direction of the inclination regulation inner surface 32 (that is, the vertical direction along the inclination regulation inner surface 32 in FIG. 5), and the front edge regulation means 4 is provided. The lower end of the tilting regulation inner surface 32 is located slightly above the lower end of the tilting regulation inner surface 32, and the upper end of the front end edge portion regulating means 4 is located slightly below the upper end of the tilting regulation inner surface 32. An abutting surface 34 that comes into contact with the front end edge of the frontmost object to be transported is provided on the upstream side of the front one-end edge regulating means 4 in the transport direction, and the object to be transported is provided with the contact surface 34 by the transport means 2. Will not be transported beyond. In the illustrated embodiment, a front surface regulating means 36 is also provided on the upstream side surface of the leg of the installation table described later for installing the back plate 10 in the transport direction, to which the front surface of the object to be transported at the front end described later is abutted. ing. The front surface regulating means 36 is a rod-shaped member having a rectangular cross section extending in the vertical direction, and when the upstream side surface in the transport direction matches the contact surface 34 in the transport direction, the object to be transported is downstream beyond the contact surface 34. It is prevented from moving to the side.

The second support member 8b is provided adjacent to the first support member 8a on the downstream side in the transport direction. The second support member 8b is a rectangular plate-shaped member, and its four corners are substantially horizontally supported by rod-shaped legs 16b.

Continuing the description with reference to FIGS. 1 to 4, the back plate 10 is arranged between the downstream end of the groove 26 and the contact surface 34 in the transport direction. The back plate 10 is composed of three plate pieces 38a to 38c. The plate pieces 38a to 38c are all rod-shaped members extending in the vertical direction, and the width of the lower end portions thereof in the transport direction is gradually reduced downward. The cross-sectional shape of the plate piece 38a excluding the lower end is a substantially rectangular shape whose length in the width direction is approximately twice as long as the length in the transport direction. The cross-sectional shapes of the plate pieces 38b and 38c excluding the lower ends are substantially square in length in the transport direction, which is the same as that of the plate pieces 38a. On the downstream side surface of the plate piece 38a in the transport direction, a detection switch 39 that is closed when the object to be transported comes into contact with the plate piece 38a is disposed. The plate pieces 38a to 38c are arranged side by side in the width direction so that the widthwise distance between the plate pieces 38a and the plate piece 38b is approximately twice the widthwise distance between the plate pieces 38b and the plate pieces 38c. It is fixed to the fixing member 40.

The plate piece fixing member 40 includes an upstream member 40a and a downstream member 40b extending linearly in the width direction. Both the upstream member 40a and the downstream member 40b are plate-shaped members having a rectangular cross section, and the upper surface of the upstream member 40a and the upper surface of the downstream member 40b are connected by a hinge portion 40c. The upper ends of the plate pieces 38a to 38c are fixed to the upstream member 40a. On the other hand, the downstream member 40b is installed in the upright portion 42a of the L-shaped member 42. At this time, a rail 44 extending linearly in the vertical direction is disposed on the upstream side surface of the upright portion 42a of the L-shaped member 42 in the transport direction, and the downstream member 40b is installed on the rail 44 via an actuator (not shown). It becomes movable in the vertical direction. Therefore, the back plate 10 fixed to the plate piece fixing member 40 can also move in the vertical direction. The L-shaped member 42 is installed on an installation table 46 provided on the second support member 8b. The installation table 46 has a rectangular top plate 48 that is positioned above the tilt regulation upper surface 24 when viewed in the vertical direction and is substantially horizontal, and a plurality of top plates 48 that support the top plate 48, in the illustrated embodiment. It is equipped with five legs 50. A rail 52 extending linearly in the transport direction is formed on the upper surface of the top plate 48, the horizontal portion 42b of the L-shaped member 42 is connected to the rail 52 via an actuator (not shown), and the L-shaped member 42 is connected to the rail 52. It becomes movable in the transport direction. Therefore, the back plate 10 disposed on the L-shaped member 42 via the plate piece fixing member 40 is also movable in the transport direction. Furthermore, since the upper surface of the upstream member 40a to which the back plate 10 is fixed and the downstream member 40b to which the L-shaped member 42 is connected is connected by the hinge portion 40c, the back plate 10 has the hinge portion 40c. It can also be elastically retracted upstream in the transport direction as the center of rotation. All of the above actuators are a part of compressed air control equipment (not shown), and use compressed air as an operating power source.

Explaining with reference to FIGS. 7-1 to 7-3, the back plate 10 is separated from the frontmost object to be transported, which will be described later, by a first predetermined distance D1 rearward (that is, on the upstream side in the transport direction) by the actuator. It is movable between the retracted position and the forward position that has advanced (that is, moved in the downstream direction in the transport direction) a second predetermined distance D2 shorter than the first predetermined distance D1 from this retracted position, and is also transported as described later. It is movable between the action position that enters between two adjacent objects to be transported and the non-action position that is separated from the objects to be transported in the objects to be transported that are sequentially upright and arranged in parallel along the path L. The retracted position of the back plate 10 in the transport direction aligns the back plate 10 with the downstream end of the groove 26 of the first support member 8a. In the illustrated embodiment, the back plate 10 moves downward from the non-acting position and is located at the acting position. When the back plate 10 is in the non-acting position, the lower end of the back plate 10 is located above the object to be transported supported by the one-side edge restricting member 22, and when the back plate 10 is in the acting position, the back plate 10 The lower end is below the upper edge (that is, the other side edge) of the object to be transported, faces the inclination regulation upper surface 24 of the one-side edge regulation member 22, and is located slightly above this. However, the back plate 10 moves periodically by the following path. That is, the back plate 10 is a retracting action position (FIGS. 7-1 (a) and 7-2 (e) to 7-3 (i)), which is a retracting position and an action position, and a forward position. The forward action position (FIG. 7-1 (b)) which is the action position, the forward non-action position (FIG. 7-1 (c)) which is the forward position and the non-action position, and the backward position and the backward position. After sequentially moving to the receding non-acting position (FIG. 7-2 (d)), which is the non-acting position, the retracting acting position (FIG. 7-1 (a) and FIGS. 7-2 (e) to 7-3 (FIG. 7-2 (e)) i) Move to).

Continuing the description with reference to FIGS. 1 to 4, the transport stand 12 is arranged inside the groove 26 in the transport direction. The transport stand 12 has a plurality of section sections 54 and a section support member 56 that supports and fixes each section 54. Each of the section pieces 54 is a rod-shaped member extending in the vertical direction, and has a substantially square cross section except for the upper end portion. In each of the upper end portions of the section 54, the width in the transport direction is gradually reduced upward. The section support member 56 has a plurality of widthwise support portions 58 (seven in the illustrated embodiment) extending in the width direction, and a pair of transport direction support portions 60 extending in the transport direction. Three partition sections 54 are fixed at predetermined positions on the downstream side surfaces of the respective width direction support portions 58 in the transport direction. These three sections 54 are aligned with the grooves 26a to c formed in the first support member 8a when the transport stand 12 is installed as required for the first support member 8a. (See FIG. 3), the lower ends of each are fixed. Each of the widthwise support portions 58 is a pair of transport portions parallel to each other and so that the transport direction spacing of the section 54 is a spacing (X) corresponding to the spacing between the retracted position and the forward position of the back plate 10. It is fixed to the upper surface of the directional support portion 60. A pair of rails 62 extending in the transport direction are formed on the lower surfaces of each of the pair of transport direction support portions 60, and the rails 62 are connected to the bottom plate 64 via an actuator (not shown). Therefore, the transport stand 12 is movable in the transport direction. Further, an actuator 66 for raising and lowering the bottom plate 64 so as to be movable in the vertical direction is also provided on the lower surface of the bottom plate 64, whereby the transport stand 12 can be moved in the vertical direction as well. All of the above actuators are part of compressed air control equipment (not shown), and use compressed air as the operating power source.

Explaining with reference to FIGS. 7-1 to 7-3, in the transport stand 12, the section 54 at the downstream end (frontmost end) in the transport direction is X from the retracted position of the back plate 10 when viewed in the transport direction by the actuator. A retreat position located by moving backward by (= D2) and a forward position advanced by a second predetermined distance D2 from this retreat position (hence, retreat of the partition 54 and the back plate 10 at the downstream end in the transport direction at the forward position). (The position is the same position in the transport direction), and the sections 54 are adjacent to each other in the transported object, which is sequentially arranged in parallel along the transport path L, as will be described later. It is movable between the action position that enters between the two objects to be transported and the non-action position that separates from the objects to be transported. In the illustrated embodiment, the transport stand 12 moves upward from the non-acting position and is located at the acting position. When the transport stand 12 is in the working position, the upper end of the section 54 is located above the upper surface 24 of the inclination regulation of the one-side edge regulating member 22, and when the transport stand 12 is in the non-acting position, the section 54 is located. The upper end of is located below the object to be transported supported by the first support member 8a. However, the transport stand 12 is periodically moved by the actuator in the following path. That is, the transport stand 12 is a retracting action position (FIGS. 7-1 (a), 7-3 (h) and (i)) which is a retracting position and an acting position, and is an advancing position and an acting position. Forward action position (FIGS. 7-1 (b) to 7-2 (e)), forward non-action position which is forward position and non-action position (FIG. 7-2 (f)), backward position. In addition, after sequentially moving to the receding non-acting position (FIG. 7-3 (g)) which is the non-acting position, the retracting acting position (FIG. 7-1 (a), FIG. 7-3 (h) and ( i) Move to).

Continuing the description with reference to FIGS. 1 to 4, the holding member 14 is arranged between the groove 26a and the groove 26c in the width direction. The holding member 14 includes a plurality of first holding pieces 68 and a plurality of second holding pieces 70. Each of the first holding pieces 68 is a rod-shaped member having the same cross-sectional shape as the partition 54 of the transport stand 12 and extends in the vertical direction (that is, in the vertical direction), but the width in the transport direction of the lower end portion instead of the upper end portion is downward. It is gradually reduced toward. The first holding piece 68 is supported and fixed by the first holding piece supporting member 72 above the first supporting member 8a, more specifically, the inclination regulating upper surface 24 of the one-side edge regulating member 22. The first holding piece support member 72 has a plurality of widthwise support portions 74 (six in the illustrated embodiment) extending in the width direction, and one transport direction support portion 76 extending in the transport direction. Two first holding pieces 68 are fixed at predetermined positions on the upstream side surfaces of the respective width direction support portions 74 in the transport direction. When the first holding piece support member 72 is connected to the support frame described later, as is clearly understood by referring to FIG. 3, the first holding piece 68 is unilateral in the width direction. In the transport direction, the back plate 10 is moved upstream by X from the retracted position (states shown in FIGS. 1 to 4) so as to be evenly spaced between the grooves 26b and the grooves 26c formed in the edge regulating member 22. Starting from the position where the position is set, the positions are sequentially positioned with an interval of X toward the upstream side.

The first holding piece support member 72 that supports and fixes the plurality of first holding pieces 68 is movably supported in the vertical direction by the support frame 78 above the inclination regulating upper surface 24 of the one-side edge regulating member 22. The support frame 78 has a U-shaped upstream frame portion 80 arranged adjacent to the upstream end of the first support member 8a in the transport direction and having an open lower portion, a width direction of the upper side of the upstream frame portion 80, and the like. A linear intermediate frame portion 82 that extends substantially horizontally from an end portion (the right end portion in FIG. 4) toward the downstream in the transport direction and is connected and fixed to the installation table 46, and a substantially intermediate portion in the transport direction of the intermediate frame portion 82. It has a U-shaped upper frame portion 84 fixed to the upper surface of the above and open downward. A pair of rails 86 extending linearly in the vertical direction are formed on one side (left side in FIG. 4) in the width direction of a pair of sides facing each other in the upper frame portion 84 in the transport direction. The holding piece support member 72 is movably connected to the rail 86 in the vertical direction via an actuator (not shown). Therefore, the first holding piece 68 fixed to the first holding piece support member 72 is also movable in the vertical direction.

The second holding piece 70 is composed of a substantially hemispherical protrusion 88 projecting upward and a rod 90 connected to the lower surface of the protrusion 88. The second holding piece 70 is housed in a small hole 28 formed in the one-side edge regulating member 22, respectively, and all the second holding pieces 70 are simultaneously accommodated by a connecting member and an actuator (not shown) on the tilting regulating upper surface of the one-sided edge regulating member 22. It is movable in the direction perpendicular to 24. As described above, each of the small holes 28 is spaced X from a position moved upstream by X from the retracted position of the back plate 10 (states shown in FIGS. 1 to 4) when viewed in the transport direction. Therefore, each second holding piece 70 is aligned with each first holding piece 68 in the transport direction.

Explaining with reference to FIGS. 7-1 to 7-3, the holding member 14 is adjacent to the object to be transported, which is sequentially arranged in parallel along the transport path L by an actuator for operating the holding member 14. The acting position (FIGS. 7-2 (e) to 7-3 (h)) that enters between the two objects to be transported and the non-actuating position (FIGS. 7-1 (a) to 7-3 (h)) that separates from the object to be transported. It is movable between 7-2 (d) and 7-3 (i). In the illustrated embodiment, the first holding piece 68 moves downward from the non-acting position and is located at the working position, and the second holding piece 70 moves upward from the non-acting position and is located at the working position. .. When the first holding piece 68 is in the non-acting position, the lower end of the first holding piece 68 is located above the object to be transported supported by the first support member 8a, and the first When the holding piece 68 is in the working position, the lower end of the first holding piece 68 is below the other side edge of the object to be transported, faces the inclination regulating upper surface 24 of the one side edge regulating member 22, and is more than this. Located minutes above. When the second holding piece 70 is in the non-acting position, the upper end of the protrusion 88 is below the object to be transported supported by the one-side edge restricting member 22, and more specifically, the upper end of the protrusion 88 is one-side edge regulation. It is located inside a small hole 28 provided in the member 22 (that is, between the upper surface and the lower surface of the one-side edge regulating member 22). On the other hand, when the second holding piece 70 is in the action position, the upper end of the protrusion 88 is located above the inclination restricting upper surface 24 of the one-end edge regulating member 22. The first holding piece 68 and the second holding piece 70 can be simultaneously switched from the non-action position to the action position and from the action position to the non-action position by an appropriate control means.

Continuing the description with reference to FIGS. 1 to 4, the separation and unloading means 6 is supported by the first support member 8a at the upstream end of the second support member 8b in the transport direction, as will be described later. It is arranged so as to face the frontmost object to be transported by a large number of objects to be transported. At least two separate unloading means 6 are arranged at intervals in the direction from one side edge to the other side edge where the object to be transported is regulated, and are located facing the frontmost object to be transported (not shown). In the embodiment, four suction tools 92) and a common support member 94 to which they are mounted are provided. The suction tool 92 has a bowl shape formed of an appropriate soft synthetic resin having flexibility such as an elastomer material, and a suction hole 96 (see FIG. 4) is formed at the central top thereof. The common support member 94 is a substantially prism member that is long in the direction from one side edge to the other side edge (hence the vertical direction) where the object to be transported is regulated, and a plurality of connection valves (not shown) are installed on the upstream side surface in the transport direction. Has been done. Each connection valve has two ports, one of which is connected to the suction hole 96 of the suction tool 92 and the other of which is connected to a vacuum pump (not shown) via a hose (not shown). When the suction tool 92 is connected to the connection valve, the suction hole 96 faces the upstream side in the transport direction, and the vacuum pump generates a negative pressure in the inner region of the suction tool 92 (that is, the inner region of the bowl). It is possible to make it. The vacuum pump can be appropriately switched between an operating state and a non-operating state, and by switching the operation of the vacuum pump, the suction tool 92 can be switched between an operating state in which the negative pressure is generated and a non-operating state in which the negative pressure is not generated. .. In the illustrated embodiment, the suction tools 92 are arranged linearly at intervals in the vertical direction of the common support member 94 (each suction tool is arranged in order from the upper end to the lower end of the common support member 94, 92a. Represented by d). The suction tools 92a and 92d are arranged at the upper end and the lower end of the common support member 94, respectively, and the suction tools 92b and 92c are arranged so that the suction tools 92b to 92d are evenly spaced in the vertical direction under the common support member 94. They are arranged respectively. The distance between the suction tool 92a and the suction tool 92b is larger than the distance between the suction tool 92b and the suction tool 92c (the distance between the suction tool 92c and the suction tool 92d). An actuator 98 for operating the common support member 94 is installed on the downstream side surface in the transport direction of the common support member 94. Here, it is preferable that at least the suction tool 92a is rotatable around a turning center axis closer to the regulated one-sided edge of the object to be transported (hence, which is located lower in FIG. 5). In the illustrated embodiment, the actuator 98 supports the common support member 94 so that it can be swiveled and driven at the swivel center axis 100 defined between the suction tools 92a and 92b, and thus the suction tools 92a to d. Can be swiveled around the swivel center axis 98 as a unit. The actuator 98 is a part of a compressed air control device (not shown), and uses compressed air as an operating power source.

Explaining with reference to FIG. 5, the suction tools 92a to d are in forward positions where the common support member 94 to which they are mounted abuts on the front surface of the frontmost object to be conveyed, which will be described later, by being operated by the actuator 98. It becomes movable in the transport direction (front-back direction) (that is, it can move forward and backward) between it and the retracted position retracted in the direction away from the front surface of the object to be transported at the front end, and acts on the object to be transported at the front end. It becomes movable in the lateral direction (left-right direction) perpendicular to and horizontal to the transport direction between the action position to be carried and the discharge position to discharge the transported object, and the suction tool 92a is further separated from the one-side edge restricting member 22. It becomes freely swivel around the swivel center axis 100 between the approach position approaching the one-end edge restricting member 30 and the separation position away from the one-end edge regulating member 30 and approaching the one-side edge regulating member 22 (suction tool). The direction in which 92a moves away from the one-sided edge regulating member 30 and approaches the one-sided edge regulating member 22 is called the separation direction). Therefore, in the illustrated embodiment, the suction tools 92a to 92 move periodically as follows. That is, the suction tool 92 moves forward in the front-rear direction from the reference state (backward position in the front-rear direction, approach position in the separation direction, action position in the left-right direction) shown in FIG. 5A, and is positioned in the forward position (FIG. 5). (B)), then swivel from the approach position to the separation position in the separation direction (FIG. 5 (c)), then retract from the forward position to the retract position in the front-back direction (FIG. 5 (d)), and then in the separation direction. In, laterally moves from the action position to the release position in the left-right direction while maintaining the separation position (FIG. 5 (e)), and then turns from the separation position to the approach position in the separation direction from the release position to the action position in the left-right direction. It moves laterally and returns to the reference state shown in FIG. 5A again.

Subsequently, the operation of the unloading device configured according to the present invention will be described with reference to FIGS. 7-1 to 7-3 together with FIG.
First, prior to operating the unloading device, the operator manually arranges a large number of objects to be transported C on the first support member 8a in a state of being sequentially upright and parallel along the transport path L. As shown in FIG. 7-1 (a), the object to be transported C is not only between the section 54 adjacent to each other in the transport direction, but also between the section 54 at the downstream end in the transport direction and the back plate 10 and back. It is also arranged between the plate 10 and the suction tool 92. When performing such work, the suction tool 92 of the separation / carrying-out means 6 is in an inactive state, the back plate 10 is in the retracting action position, the transport stand 12 is in the retracting action position, and the holding member 14 (that is, the first one). The holding piece 68 and the second holding piece 70) are located in the non-acting position, respectively. Here, the flat plate-shaped object to be transported is a well-known package called a pouch for accommodating, for example, a liquid detergent or retort food, and has a one-end edge portion called a so-called standing pouch as shown in FIG. UP (upper end edge in FIG. 6) is thinner than the other end edge BP (lower end edge in FIG. 6), and one end edge UL and the other end edge BL are both side edges (one side edge RL and the other side edge LL, that is, It also includes a pair of edges connecting one end edge UL and the other end edge BL, which are shorter than the pair of edges extending in the vertical direction in FIG. The present invention is suitable for transporting the standing pouch. In the standing pouch, one end edge UP is opened while being transported by the unloading device of the present invention, but after being transported by the unloading device of the present invention and filled with the contents, the one end edge UP is opened. It is blocked. In each of the objects to be transported, the one-side edge RL and the one-end edge UL are regulated by the inclination regulation upper surface 24 of the one-side edge regulation member 22 and the inclination regulation inner surface 32 of the one-end edge regulation member 30, and the objects to be transported are adjacent to each other in the transport direction. They are supported in an upright parallel arrangement that stands substantially vertically in a state where they are in surface contact with each other (see FIGS. 5 (a) and 7-1 (a)).

When the operation of the unloading device is started, the separation unloading means 6 is activated to start the transport of the transported object C supported by the first support member 8a. The operation of the separate carrying-out means 6 will be described with reference to FIG. In this figure (and the same applies to FIG. 8 to be referred to later), the schematic diagram when viewed from the downstream side to the upstream side in the transport direction is arranged on the left side, and the schematic diagram viewed from above is arranged on the right side. In the arranged figures, the suction tool 92 is shown only for the suction tools 92a and 92d for the sake of simplification of the figure, and the others are omitted. It is attached and shown.

The suction tools 92a to d of the separation / carry-out means 6 operate as follows. That is, first, the suction tools 92a to 92d are in the reference state shown in FIG. 5A. At this time, the suction tool 92a to d may be in an operating state or a non-operating state. Next, the suction tools 92a to 92d are advanced to the forward position in the front-rear direction, come into contact with the front surface of the object to be transported C1 at the foremost end, and are brought into an operating state (FIG. 5 (b)). At this time, the suction tools 92a to d are brought into contact with the inner surface in the left-right direction from the front end edge portion of the front end of the object to be transported C1, and the bowl-shaped portion of the suction tools 92a to d is with the object to be transported C1. It is in close contact and deformed. Then, the suction tools 92a to 92 suck and hold the frontmost transported portion C1 by the negative pressure generated by the vacuum pump (not shown). Next, the suction tool 92a located at a position far from the restricted one-sided edge of the object to be transported C is moved in the separation direction. In the illustrated embodiment, the suction tool 92a is attached to the common support member 94 together with the suction tools 92b to d, and when the common support member 94 is swiveled in the counterclockwise direction in FIG. 5 (c), the suction tool 92a to d is integrally swiveled from the approaching position to the separation position in the separation direction (FIG. 5 (c)). In this way, the distance between the suction tool 92a and the one-side edge restricting member 22 becomes short, whereby the portion to be sucked and held by the suction tool 92a in the object to be transported C1 and one side regulated by the inclination regulation upper surface 24 of the one-end regulation member 30. By shortening the distance from the edge RL, the transported object C1 is compressed and a part thereof is curved and projected forward, so that the transported object C1 at the front end and immediately after this (that is, the second from the front) It is separated from the positioned object to be transported C2. After that, the suction tools 92a to 92d are moved backward from the forward position to the backward position in the front-rear direction while maintaining the state of the separation position in the separation direction (FIG. 5 (d)). At this time, since the transported object C1 and the transported object C2 are surely separated in the state shown in FIG. 5 (c), the suction tools 92a to d reliably secure only the frontmost transported object C1. It can be separated from the front end edge regulating means 4, that is, carried out from the transport means 2. After that, as shown in FIG. 5 (e), the suction tools 92a to d move from the action position to the release position in the left-right direction while maintaining the state of the separation position in the separation direction, and are not in the operating state at such a position. It can be switched to the operating state. Then, the transported object C1 sucked by the suction tools 92a to d is delivered to an appropriate feeding means 102 such as a nip roller indicated by a two-dot chain line, and the transported object C1 is discharged. After releasing the transported object C1, the suction tools 92a to 92 move from the release position to the action position in the left-right direction while being swiveled from the separation position to the approach position in the separation direction, and are shown again in FIG. 5 (a). It becomes the standard state.

Therefore, in the unloading device of the present invention, regardless of whether or not there is a member that regulates the other end edge of the transported object C, the direction from the regulated one side edge of the transported object C toward the other side edge. The suction tools 92a to 92d are moved away from the regulated one-end edge of the object to be transported and regulated in a state where the suction tools 92a to d arranged at intervals are attracted to the front surface of the object to be transported C1 at the front end. By moving in the separation direction approaching the one-sided edge, the transported object C1 is compressed and a part thereof is curved and projected forward, so that the one-ended edge portion of the transported object is restricted from the one-ended edge portion regulating means 4. It can be withdrawn.

Each time one or more items C to be transported are carried out by the above operation of the separation and carrying-out means 6, the back plate 10 and the transfer stand 12 are provided with a distance corresponding to the thickness of one or more items C to be transported. Advance. In the back plate 10 and the transport stand 12, the detection switch 39 provided on the downstream side surface in the transport direction of the back plate 10 is brought into contact with the transported object C (that is, the detection switch 39 is relatively pressed by the transported object C). It stops when it is closed. Even after the back plate 10 and the transport stand 12 are stopped, the above-mentioned operation of the separate / carry-out means 6 is continued. When the separation / unloading means 6 continues the above operation with the back plate 10 and the transport stand 12 stopped, the number of objects to be transported C between the separation / unloading means 6 and the back plate 10 decreases, and the transfer target C reduces the number of objects to be transported. The contact with the detection switch 39 (that is, the pressing of the detection switch 39 by the object to be transported C) is released, and the detection switch 39 is released. When the detection switch 39 is opened, the back plate 10 and the transfer stand 12 move forward again. By doing so, the suction of the suction tool 92 to the transported object C is damaged due to the excessive pressing of the back plate 10 against the transported object C, and the separation / carrying out means 6 appropriately selects the transported object C. It is prevented that it cannot be transported to. In the illustrated embodiment, the operation of both the back plate 10 and the transport stand 12 is controlled by switching the detection switch 39 provided on the back plate 10, but if desired, the downstream end of the transport stand 12 in the transport direction. A second detection switch is provided on the downstream side surface of the section 54 located in the transport direction so that the operation of the transport stand 12 is controlled independently of the operation of the back plate 10 by switching the second detection switch. May be good.

When the back plate 10 and the transport stand 12 advance from the respective retracting action positions shown in FIG. 7-1 (a) to the respective forward acting positions shown in FIG. 7-1 (b), the back plate 10 advances from the forward acting position. It moves to the non-acting position (FIG. 7-1 (c)), then to the retracted non-acting position (FIG. 7-2 (d)), and then to the retracting acting position and the holding member 14 (ie, that is). The first holding piece 68 and the second holding piece 70) move from the non-acting position to the acting position (FIG. 7-2 (e)). This movement of the holding member 14 may be during the movement of the back plate 10 from the forward action position to the backward action position or after the movement is completed. In the state shown in FIG. 7-2 (e), the back plate 10 and the partition portion 54 at the foremost end of the transport stand 12 match in the transport direction, but the plate piece 38a constituting the back plate 10 and the auxiliary plate Since the pieces 38b and 36c and the section 54 located at the foremost end of the transport stand 12 are different in position in the width direction, the plate pieces 38a, the auxiliary plate pieces 38b and 36c and the section 54 do not interfere with each other. Similarly, the first holding piece 68 and the second holding piece 70 and the partition 54 of the transport stand 12 match in the transport direction, but the first holding piece 68 and the second holding piece 70 and the transport stand 12 Since the positions of the section 54 are different from those of the section 54 in the width direction, the first holding piece 68 and the second holding piece 70 do not interfere with the section 54 (see FIG. 3). During the movement of the back plate 10 and the holding member 14, the separation / carrying out means 6 continuously conveys the object to be conveyed C supported by the first support member 8a.

After the holding member 14 moves from the non-acting position to the acting position, the transport stand 12 moves from the forward acting position to the forward non-acting position (FIG. 7-2 (f)) and then to the retracting non-acting position (FIG. 7-2 (f)). 7-3 (g)), and then move to the retracting action position (Fig. 7-3 (h)). Then, after the transport stand 12 moves to the retracting action position, the holding member 14 moves from the action position to the non-action position (FIG. 7-3 (i)). During the above movement of the transport stand 12 and the holding member 14, the separation and unloading means 6 continuously transports the object to be transported C supported by the first support member 8a.

The state shown in FIG. 7-3 (i) and the state shown in FIG. 7-1 (a) are a section 54 located at the end of the transport stand 12 in the transport direction and adjacent to the section 54 in the transport direction. Only the presence or absence of the transported object C in the region between the section 54 and the section 54 is different, but the other conditions are the same. By repeating the above operation, the transported object C can be continuously transported. Further, the worker can replenish the vacant area of the transported object C with a new transported object C, so that the transported object C can be continuously transported for a long time.

Subsequently, with reference to FIG. 8, a first modification of the operation of the separate and carry-out means in the carry-out device of the present invention will be described.
In the embodiment shown in FIG. 8, the actuator 98 of the separation / carrying-out means 6 can move the common support member 94 forward / backward and in the left-right direction, but the actuator 98 alone moves the common support member 94 around the turning center axis 100. It cannot be driven to turn. Further, in the embodiment shown in FIG. 8, the lower limiting piece 104a, which restricts the movement of the lower end portion of the common support member 94 when it moves to the left in FIG. 8, and the common support member 94 on the right in FIG. One lower limit piece 104b and one upper limit piece 104c that restrict the movement of the lower end portion and the upper end portion when moving in the direction are provided (the other lower limit piece 104a, the one lower limit piece 104b, And on the other hand, the upper limit piece 104c is shown only in FIG. 8).

In the embodiment shown in FIG. 8, the suction tools 92a to d of the separation / carry-out means 6 operate as follows from the state of sucking and holding the frontmost object to be transported C1 (the state shown in FIG. 8B). (FIGS. 8 (a) and 8 (b) are both in the same state as in FIGS. 5 (a) and 5 (b)). That is, as shown in FIG. 8C, the suction tools 92a to 92 move horizontally in a direction away from the one-end edge restricting member 30 when viewed in the left-right direction. Then, the lower end portion of the common support member 94 abuts on the other lower limiting piece 104a, and the common support member 94 is swiveled counterclockwise in FIG. 8 (c) about the swivel center axis 100. As a result, the suction tools 92a to 92 provided on the common support member 94 are also swiveled from the approach position to the separation position in the separation direction (FIG. 8 (c)). At this time, as described above, the transported object C1 at the foremost end and the transported object C2 located immediately after this (that is, the second from the front) are separated. After that, the suction tools 92a to 92d are moved backward from the forward position to the backward position in the front-rear direction while maintaining the state of the separation position in the separation direction (FIG. 8 (d)). After that, the suction tools 92a to 92d move from the action position to the release position in the left-right direction as shown in FIG. 8 (e). At the discharge position, the lower end portion and the upper end portion of the common support member 94 come into contact with the one lower limit piece 104b and the one upper limit piece 104c, respectively, so that the suction tools 92a to d are set to the separation positions in the separation direction. Then, in the state shown in FIG. 8 (e), the suction tools 92a to 92d are switched from the operating state to the non-operating state, and the transported object C1 is released. After releasing the object to be transported C1, the suction tools 92a to 92 are swiveled from the separation position to the approach position in the separation direction by an appropriate posture returning means (not shown) such as a restoring force by a spring, and from the release position in the left-right direction. It is moved to the action position and returns to the reference state shown in FIG. 8 (a) again.

Although the carrying-out device of the present invention has been described in detail with reference to the accompanying drawings, the present invention is not limited to the above-described embodiment, and various modifications or modifications can be made without departing from the scope of the present invention. be. For example, in the present embodiment, the one-side edge regulating member is tilted because the first support member is tilted in the width direction, but instead of this, the first support member is horizontal and one side. The edge restricting member may also be substantially horizontal. Further, in the present embodiment, the first support member is composed of one flat plate and a groove is formed in the flat plate. Instead, a plurality of flat plates extending in the transport direction of the support substrate are formed in the width direction. They may be spaced apart so that grooves are defined between adjacent flat plates in the width direction. Further, in the present embodiment, the transport path extends linearly in the horizontal direction, but instead, the transport path may extend in a curved line or in the vertical direction. Further, in the present embodiment, the suction tool can be swiveled in the separation direction about the turning center axis, but instead of this, the suction tool may be moved linearly in the separation direction.

Furthermore, in the present embodiment, at least two suction tools are arranged at intervals in the width direction of the object to be transported, but instead, the suction tools extend in the width direction of the object to be transported. It may be a single one. If the suction tool is a single one extending in the width direction of the transported object, the suction tool is restricted to the end of the transported object far from one side edge where the transported object is regulated. Allows movement in the separation direction and vice versa, away from the existing one-sided edge and approaching the regulated one-sided edge. Also in this case, regardless of whether or not there is a member that regulates the other end edge of the transported object, the suction tool extending in the width direction of the transported object is attracted to the front surface of the transported object at the foremost end. In the state, the end farther from the regulated one-sided edge of the transported object moves away from the regulated one-sided edge of the transported object and approaches the regulated one-sided edge, thereby moving in the separation direction. The transported object can be compressed and a part thereof can be curved and projected forward so that the one-end edge portion of the transported object can be separated from the one-end edge portion regulating means.
