Description

  The present invention relates to an unloading device for sequentially unloading a flat bag-like article, for example, a packaging bag called a standing pouch for containing a liquid detergent or a retort food.

  As a conventional unloading device for unloading a flat plate-like object such as a packaging bag called a standing pouch sequentially one by one, the unloading device disclosed in the following Patent Document 1 and the following Patent Document 2 Can be mentioned.

  The unloading device disclosed in the following Patent Document 1 includes a transport conveyor that transports a large number of transported objects that are stacked and shifted by a shift dimension of, for example, about 8 to 10 mm in the transport direction; Separating means for separating one transported object located downstream and other transported objects positioned downstream and upstream in the transport direction; and unloading means for moving the separated transported object in a required direction It comprises.

  The unloading device disclosed in the following Patent Document 2 is a supporting means for supporting a large number of objects to be conveyed in a stacked state, and a means for supporting the objects to be conveyed in the lowermost layer through an unloading opening formed in the bottom wall of the supporting means. And unloading means for unloading from the bottom.

Japanese Patent No. 5897999 Japanese Patent Laying-Open No. 2015-221667

  In the unloading apparatus disclosed in the above-mentioned Patent Document 1, it is necessary to manually stack and arrange a large number of objects to be conveyed on the conveyor by shifting the dimensions in the conveying direction, and this operation is considerably complicated. When a relatively large error occurs in the deviation size, it is difficult to separate one by one, and there is a tendency that two or more objects to be conveyed are carried out at the same time. In order to stack and arrange the objects to be conveyed, there is a problem that it is necessary to considerably lengthen the conveying direction length of the conveyor.

  On the other hand, in the unloading device disclosed in the above-mentioned Patent Document 2, when the number of objects to be stacked stacked on the support means is increased, the weight of the entire object to be conveyed increases, and therefore the object to be conveyed in the lowermost layer. The frictional resistance between the lower surface of the support and the bottom wall of the support means increases, which makes it difficult to carry out the object to be conveyed through the unloading opening, or to carry out two or more objects to be conveyed at the same time. There is a problem that there is a risk of losing.

  In view of the above facts, the present inventors previously described a number of support devices on the support means as the carry-out device that solves the above-described problems existing in the conventional carry-out device in the specification and drawings of Japanese Patent Application No. 2016-211652. A large number of transported objects arranged in parallel along the predetermined transport path, with the state-of-the-art transported objects being sequentially carried out and one or more transported objects being carried out in parallel. A unique form of unloading apparatus has been proposed (hereinafter referred to as “preceding unloading apparatus”) that can appropriately move an object downstream in the conveying direction. The preceding carry-out device includes a one-side edge regulating upper surface and a one-end edge regulating inner surface for regulating one side edge and one end edge of a flat plate-like object to be conveyed, and a large number of objects to be conveyed are sequentially arranged in a standing manner along a predetermined path. Conveying means forcing in the conveying direction along a predetermined path in a state where the front edge of the front edge of the object to be conveyed is in contact with the front edge of the front edge, and a front edge of the object to be conveyed. A transporting object unloading means disposed opposite to each other, separating the foremost transported object from the front edge portion regulating means and separating from the next transported object and unloading from the transporting means; And other end edge regulating means for regulating the other end edge of the conveyed product.

  The transported object carry-out means includes a plurality of suction tools that are selectively set to the suction operation state, and the plurality of suction tools sucks and holds the front surface of the transported object at the foremost end. Is movable in the width direction from one end edge to the other end edge. The other end edge regulating means is a fixed member that extends toward the upstream in the conveying direction in a state where one end is connected to a leg of an installation table that supports a back plate that is a part of the conveying means.

  Thus, the preceding transport apparatus is not sufficiently satisfactory, and has the following problems to be solved. When a plurality of suction tools move in the width direction from one edge of the transported object to the other edge while holding the front surface of the transported object at the foremost end, surface friction between the transported objects, vibration, etc. Accordingly, the object to be conveyed at the front end may be moved in the width direction from one edge of the object to the other edge. When the transported object moved in the width direction reaches the foremost end, the suction tool cannot suck and hold the foremost transported object at an appropriate position, and the transported object unloading means moves from the transporting means to the foremost end. There is a possibility that the object to be conveyed cannot be carried out, or the front edge portion of the foremost object to be conveyed is not regulated by the front surface edge edge regulating means, and the object to be conveyed falls. Therefore, the other end edge restricting means for restricting the other end edge of the object to be conveyed at the front end portion is provided, and the movement of the front end portion in the width direction described above is restricted by the operation of the object to be conveyed unloading means. However, in the preceding apparatus, since the other end edge regulating means is a fixed member as described above, the other end is changed when the length of the side edge of the object to be conveyed is changed. It is necessary to perform a relatively complicated manual operation of changing the mounting position of the edge regulating means each time.

  The present invention has been made in view of the above-mentioned fact, and the main technical problem thereof is a relatively complicated manual operation even when the length of the side edge of the object to be conveyed is changed to a different one. It is an object of the present invention to provide a new and improved unloading apparatus that does not have to perform the above.

  The present inventors continue further diligent examination and experiment, and include the other end edge restricting pieces in which the other end edge restricting means is arranged in a large number at intervals in the width direction at the position facing the foremost transport object. Of the other end edge restricting pieces arranged in a large number, the other end edge restricting piece that does not come into contact with the front surface of the foremost object to be conveyed is upstream of the upstream end face of the front face end edge restricting means when viewed in the carrying direction. And the other end edge restricting piece that contacts the front surface of the foremost object to be conveyed is contracted to be the same as or downstream from the upstream end face of the front face end edge restricting means when viewed in the carrying direction. We have found that technical problems can be achieved.

That is, according to the first aspect of the present invention, the unloading device that achieves the main problem includes a one-side edge regulation upper surface and a one-edge regulation inner surface that regulate the one-side edge and one-end edge of the flat plate-like object, respectively. A conveying means forcing a large number of objects to be conveyed in a standing and parallel arrangement along a predetermined path toward a conveying direction along the predetermined path, and a front edge of the front end of the object to be conveyed correspond to each other. The front-side one edge regulating means that is in contact with the front-most object to be conveyed is disposed so as to separate the front-most object from the front-side edge regulating means and to be separated from the next object to be conveyed. And a transported object unloading means for unloading from the transporting means, and another end edge regulating means for regulating the other end edge of the transported object at the front end,
The transported object carrying means includes a plurality of suction tools that are selectively set in a suction operation state, and the plurality of suction tools are at least held in a state where the front surface of the transported object at the foremost end is sucked and held. A part is movable in the width direction from one end edge of the conveyed object to the other end edge,
The other end edge restricting means includes a plurality of other end edge restricting pieces that are arranged in the width direction so as to be opposed to the foremost object to be conveyed, and each of the many other end edge restricting pieces that are arranged. Is between the protruding position protruding upstream from the upstream end face of the front side edge portion regulating means and the retracted position that is the same as or downstream from the upstream end face of the front side edge edge regulating means when viewed in the transport direction. The other end edge regulating piece that comes into contact with the front surface of the foremost transport object among the other end edge restricting pieces arranged in a large number is moved to the retracted position, and the foremost transport object is An unloading device is provided in which the other end edge regulating piece that does not come into contact with the front surface of the plate moves to the protruding position.

  Preferably, the other end edge restricting means has a common support member that accommodates the plurality of other end edge restricting pieces arranged and abutted with the front surface of the transported object at the foremost end. A plurality of bottomed grooves each having a bottom surface that is inclined downward from the downstream to the upstream when viewed in the conveying direction and at least the upstream surface is open are formed at intervals in the width direction. Each of the arranged other end edge regulating pieces has a thin disc shape, and is inserted into the bottomed groove while being supported by the bottom surface. Preferably, an opening is formed in the center of the other end edge restricting piece, and the other end edge restricting piece moves upstream beyond the protruding position by being inserted into the opening in the bottomed groove. A limiting shaft is formed to limit the operation.

  Further, the present inventors have found that the main technical problem can be achieved by providing a large number of engagement surfaces that are sharply cut upward toward the inner surface of the one-end edge regulation in the width direction on the upper surface of the one-side edge regulation. It was.

That is, according to the second aspect of the present invention, the unloading device that achieves the main problem includes a one-side edge regulation upper surface and a one-edge regulation inner surface that regulate the one-side edge and one-end edge of the flat plate-like object, respectively. A conveying means forcing a large number of objects to be conveyed in a standing and parallel arrangement along a predetermined path toward a conveying direction along the predetermined path, and a front edge of the front end of the object to be conveyed correspond to each other. The front-side one edge regulating means that is in contact with the front-most object to be conveyed is disposed so as to separate the front-most object from the front-side edge regulating means and to be separated from the next object to be conveyed. And a transported object carry-out means that is transported from the transport means, and a one-side edge engaging means that engages with one side edge of the transported object at the front end,
The transported object carrying means includes a plurality of suction tools that are selectively set in a suction operation state, and the plurality of suction tools are at least held in a state where the front surface of the transported object at the foremost end is sucked and held. A part is movable in the width direction from one end edge of the conveyed object to the other end edge,
The one-side edge engaging means includes an engagement surface that is sharply cut upward toward the one-end edge regulating inner surface, and a plurality of the engagement surfaces are provided in the width direction on the one-side edge regulating upper surface. An unloading device is provided.

  Preferably, the upper end edge of the engagement surface extends in the transport direction.

  According to the first aspect of the present invention, regardless of the length of the side edge of the conveyed object to be conveyed, the other end edge regulating piece located adjacent to the outer side in the width direction of the conveyed object at the front end is Since it is located at the protruding position and opposes the other end edge of the object to be conveyed at the front end, the object to be conveyed at the front end is moved in the width direction from one edge to the other edge by the operation of the object carrying-out means. Therefore, even when the length of the side edge of the object to be conveyed is changed to a different one, there is no need to perform a relatively complicated manual operation.

  According to the second aspect of the present invention, regardless of the length of the side edge of the object to be conveyed, the one side edge of the object to be conveyed at the front end portion is sharply cut upward toward the one edge regulating inner surface. Since it is engaged with the engagement surface, the movement of the conveyed object carrying means restricts the conveyed object at the front end from moving in the width direction from one edge to the other edge, and the object to be conveyed is to be conveyed. Even when the length of the side edge of the object is changed, it is not necessary to perform a relatively complicated manual operation.

And a U-shaped upper frame portion 88. A pair of rails 90 extending linearly in the vertical direction are formed on the inner surfaces in the width direction of the pair of sides facing each other when viewed in the transport direction in the upper frame portion 88, and the common support member 76 is an actuator (not shown). The rail 90 is connected to the rail 90 so as to be movable in the vertical direction. Accordingly, the holding piece 74 fixed to the common support member 76 is movable in the vertical direction.

  Referring to FIGS. 12-1 to 12-3, the holding piece 74 is adjacent to an object to be conveyed that is sequentially arranged upright along the conveyance path L as will be described later by an actuator that operates the holding piece 74. An action position (FIGS. 12-2 (e) to 12-3 (h)) entering between two objects to be conveyed and a non-action position (FIG. 12-1 (a) to FIG. 12) separated from the objects to be conveyed. 12-2 (d) and FIG. 12-3 (i)) are movable up and down. When the holding piece 74 is in the non-operating position, the lower end of the holding piece 74 is positioned above the conveyed object supported by the first support member 18 and the holding piece 74 is in the operating position. The lower end of the holding piece 74 is below the upper edge (that is, the other side edge LL that is not regulated (see FIG. 11)) of the conveyed object, and the one side edge regulation upper surface of the first support member 18. It faces 28 and is located somewhat above it.

  Referring to FIG. 5 together with FIG. 1 to FIG. 4, the transported object carrying means 4 is disposed to face the front surface of the transported object at the foremost end, and is arranged in a straight line with an interval in the vertical direction. A plurality of suction tools 92 provided, and a common support member 94 that supports all of the suction tools 92 in common are provided. In the illustrated embodiment, four suction tools 92 are provided, each of which is shown with a to d downward. The suction tools 92a to 92d are bowl-shaped formed of an appropriate soft synthetic resin having flexibility such as an elastomer material. As clearly shown in FIG. 4, a suction hole 96 is formed at the center top. Yes. The common support member 94 is a substantially prismatic member that is long in the vertical direction, and a plurality of connection valves (not shown) are installed on the upstream side surface in the transport direction. Each connection valve has two ports, one port is connected to a suction hole 96 of a suction tool 92, and the other port 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 negative pressure is generated in the inner area of the suction tool 92 (ie, the inner area of the bag) by the vacuum pump. It becomes possible to make it. The vacuum pump can be appropriately switched between an operating state and a suction non-operating state, and the suction tool 92 is switched between a suction operating state where the negative pressure is generated and a suction non-operating state where the negative pressure is not generated by switching the operation of the vacuum pump. It is free. The suction tool 92a and the suction tool 92d are respectively disposed at the upper end portion and the lower end portion of the common support member 94, and the suction tools 92b and 92c are arranged at equal intervals in the vertical direction below the common support member 94. It is arranged so as to make each. 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. The actuator 98 supports the common support member 94 so as to be pivotable about an axis R defined between the suction tool 92a and the suction tool 92b. The actuator 98 is also connected to a rail 100 extending in the width direction and a rail (not shown) extending in the transport direction, and is movable in the width direction and the transport direction. As a result, the suction tools 92a to 92d are integrally rotatable about the axis R and are movable in the width direction and the transport direction. The actuator 98 is a part of a compressed air control device (not shown), and uses compressed air as an operating power source.

  Referring to FIG. 5, the suction tools 92a to 92d are advanced positions where they come into contact with the front surface of the transported object at the foremost end, which will be described later, by operating the common support member 94 to which the suction tools 92a to 92d are attached by the actuator 98. And a retracted position retracted in a direction away from the front surface of the front-most object to be transported (that is, forward and backward movable), and a holding position for holding the front-most object to be transported It is movable in the lateral direction (that is, movable in the left-right direction) between the discharge position for discharging the conveyed object, and the suction tool 92a is separated from the one-side edge regulating upper surface 28 and approaches the one-edge regulating inner surface 36. It is possible to turn about the axis R between the approach position and the separation position that is separated from the one end edge regulation inner surface 36 and approaches the one side edge regulation upper surface 28 (the rotation direction around the axis R is called the separation direction).The turning of the suction tool 92a from the approach position to the separation position corresponds to movement in the width direction from one end edge to the other end edge of the conveyed object. Therefore, in the illustrated embodiment, the suction tools 92a to 92d move periodically as follows. That is, the suction tool 92 moves back and forth from the reference state shown in FIG. 5A (retracted position in the front-rear direction, approach position in the separation direction, holding position in the left-right direction) (FIG. 5B). Next, it turns from the approach position to the separation position in the separation direction (FIG. 5C), and then moves back and forth from the advance position to the backward position (FIG. 5D), and then maintains the separation position in the separation direction. Laterally moved from the holding position to the discharge position in the left-right direction (FIG. 5E), and then horizontally moved from the discharge position to the holding position in the left-right direction while turning from the separation position to the approach position in the separation direction. The reference state shown in FIG.

  6 and 7 together with FIGS. 1 to 5, the other end edge restricting means 6 includes a plurality of other end edge restricting means 6 arranged at intervals in the width direction at the front end of the first support member 18. An edge regulation piece 102 is included. In the illustrated embodiment, as clearly understood by referring to FIGS. 6 and 7, each of the multiple other end edge regulating pieces 102 is a thin disc shape and has a circular opening at the center thereof. 106 is formed and accommodated in the common support member 104. The common support member 104 has a substantially rectangular parallelepiped shape that is long in the width direction, and is fixed to the front end surface of the first support member 18 on the outer side in the width direction with respect to the transported object carrying-out means 4 and above the one-side edge regulating upper surface 28. It protrudes. 3, 5, and 6, the upstream end surface in the transport direction of the common support member 104 is substantially flush with the upstream end surface in the transport direction of the front side edge regulating means 3 when viewed in the width direction. is there. A large number of grooves 108 (bottomed grooves) are formed in the common support member 104 at intervals in the width direction. Each of the grooves 108 includes a bottom surface 110 that is inclined downward from the downstream to the upstream when viewed in the conveying direction, and the upstream surface and the upper surface of the groove 108 are open. The groove 108 is also provided with a limiting shaft 112 extending linearly substantially horizontally in the width direction.

  6 and 7, in the illustrated embodiment, the other end edge restricting piece 102 has the groove 108 in a state where the limiting shaft 112 is inserted into the opening 106 and supported by the bottom surface 110. Has been inserted inside. Therefore, in the natural state, the other end edge regulating pieces 102 move upstream along the bottom surface 110 along the bottom surface 110 by free fall. It is restricted by abutting. When the other end edge restricting piece 102 is in a natural state, that is, in a state where the movement of the other end edge restricting piece 102 to the upstream side in the conveying direction is restricted by the restricting shaft 112, refer to the cross-sectional view taken along the line PP in FIG. As understood from this, a part of the other end edge limiting piece 102 protrudes upstream beyond the upstream end face of the common support member 104, that is, the upstream end face of the front face end edge regulating means 3 when viewed in the transport direction. (Projecting position). On the other hand, for example, when the foremost object to be conveyed contacts the upstream end surface of the common support member 104 and the other end edge limiting piece 102 is pushed in the conveying direction, see the QQ cross-sectional view of FIG. As can be understood, the other end edge limiting piece 102 is entirely accommodated in the groove 108 and is the same as the rear face of the front face end edge regulating means 3 when viewed in the transport direction (front face end when viewed in the width direction). It becomes flush with the rear surface of the edge regulating means 3 (degenerated position). However, each of the other end edge regulating pieces 102 arranged in a large number has a protruding position protruding upstream from the upstream end face of the front side edge edge regulating means 3 as viewed in the transport direction, and an upstream side of the front side edge edge regulating means 3. It can be moved between the end face and the same or downstream degenerate position.

  If desired, the other end edge regulating means may be configured as shown in FIG. In the other end edge restricting means 6 'shown in FIG. 8, the groove 108' formed in the common support member 104 'has a bottom surface 110' and an upper surface 114 extending obliquely downward from upstream to downstream. ′, And the distance between the bottom surface 110 ′ and the top surface 114 ′ (that is, the vertical width of the groove 108 ′) is set to gradually decrease toward the upstream. The downstream surface and the upstream surface of the groove 108 ′ are opened, and the vertical width d1 of the groove 108 ′ on the upstream surface is larger than the diameter d0 of the other-end edge regulating piece 102 ′ having a thin disk shape, and the downstream surface The vertical width d2 of the groove 108 'is smaller than the diameter d0 of the other end edge regulating piece 102'. By doing in this way, the other end edge restricting piece 102 ′ is not provided with the limiting shaft 112 shown in FIG. 6, and between the protruding position indicated by the solid line in FIG. 8 and the contracted position indicated by the two-dot chain line in FIG. 8. It becomes movable.

  6 and FIG. 9 together with FIGS. 1 to 5, the one-side edge engaging means 8 is a front end portion of the first support member 18 and is more than the conveyed object carrying-out means 4. It is disposed on the one-side edge regulating upper surface 28 on the outer side in the width direction (if desired, the one-side edge engaging means 8 may be disposed on the inner side in the width direction with respect to the conveyed object carrying-out means 4). As clearly understood by referring to the RR cross section of FIG. 9, the one-side edge engaging means 8 includes an inner side surface 116 (engagement surface) that sharply stands upward toward the one-end edge regulating inner surface 36. The inner surface 116 has an outer surface 118 inclined downward in the width direction outward from the upper edge of the inner surface 116, and the inner surface 116 and the outer surface 118 are provided in succession alternately in the width direction. In the illustrated embodiment, the cross section of the one-side edge engaging means 8 has a sawtooth shape, and the ridge line 120 and the valley line 122 connecting the inner side surface 116 and the outer side surface 118 extend linearly in parallel with the conveying direction. . The inner side surface 116 and the outer side surface 118 are formed by subjecting the upper surface of the first support member 18 to appropriate machining such as cutting.

  If desired, the inner side surface 116 and the outer side surface 118 may be formed by subjecting the upper surface of the first support member 18 to appropriate machining, and separate members formed with the inner side surface 116 and the outer side surface 118. May be fixed to the first support member 18. Further, the one-side edge engaging means is not a sawtooth shape as shown in the RR cross-sectional view of FIG. 9, but a flat plate 120 ′ having a rectangular cross section as shown in FIG. 28 may be arranged so as to be overlaid in a state inclined on the inner side in the width direction. Also in the one-side edge engaging means 8 ′, as understood by referring to FIG. 10, an inner side surface 116 ′ (engagement surface) that sharply stands upward toward the one-end edge regulating inner surface 36, and the inner side surface 116. A large number of outer side surfaces 118 ′ inclined downward in the width direction outward from the upper end edge of ′ are continuously provided in the width direction.

Next, the operation of the carry-out device configured according to the present invention will be described with reference to FIG. 5 together with FIGS.
First, prior to operating the carry-out device, the operator manually arranges a large number of objects to be conveyed C on the first support member 18 in a state in which they stand up in parallel along the conveyance path L. As shown in FIG. 12A, the conveyed object C is not only between the partition pieces 60 adjacent in the transport direction, but also between the partition piece 60 at the downstream end in the transport direction and the back plate 12, and the back. It arrange | positions also between the plate 12 and the suction tool 92. FIG. When performing such work, the suction tool 92 of the conveyed product unloading means 4 is in a non-sucking state, the back plate 12 is in the retracting position, the transport stand 14 is in the retracting position, and the holding member 16 is not in operation. Each of them is located at the action position.

  Here, the flat plate-like transported object is a well-known package called a pouch for containing, for example, a liquid detergent or retort food, and one edge portion called a so-called standing pouch as shown in FIG. UP (upper edge in FIG. 11) is thinner than the other edge BP (lower edge in FIG. 11), and one end edge UL has both side edges (one side edge RL and other side edge LL, ie, one end edge UL and others). A pair of edges that connect the end edge BL and that is shorter than a pair of edges extending in the vertical direction in FIG. 11 is also included. The present invention is suitable for conveying the standing pouch. While the standing pouch is transported by the carrying-out device of the present invention, the one end edge portion UP is opened, but after being transported by the carrying-out device of the present invention and filled with the contents, the one end edge portion UP is opened. Occluded. In each of the objects to be conveyed C, the one-side edge RL and the one-end edge UL are regulated by the one-side edge regulating upper surface 28 and the one-edge regulating inner surface 36 of the support means 10 and the objects to be conveyed adjacent in the carrying direction are in surface contact with each other. In this state, it is supported in an upright parallel arrangement that stands substantially vertically (see FIG. 5A and FIG. 12A).

  When the operation of the unloading device is started, the transporting means 2, the transported object unloading means 4, and the transported object discharging means 8 are operated to transport the transported object C supported by the first support member 18. To start. The operation of the conveyed product unloading means 4 will be described with reference to FIG. In this figure, a schematic diagram of the upstream side viewed from the downstream side in the transport direction is arranged on the left side, and a schematic diagram viewed from above is arranged on the right side. In the diagram arranged on the right side, the diagram is simplified. For this reason, the suction tool 92 is shown only for the suction tools 92a and 92d, the others are omitted, and the former is shown with light ink to distinguish the suction tool 92a and the suction tool 92d.

  The suction tools 92a to 92d of the transported object unloading means 4 operate as follows. That is, first, the suction tools 92a to 92d are in the reference state shown in FIG. At this time, the suction tools 92a to 92d may be in either the suction operation state or the suction non-operation state. Next, the suction tools 92a to 92d are moved back and forth to the forward movement position so as to come into contact with the front surface of the transported object C1 at the foremost end and to be brought into a suction operation state (FIG. 5B). At this time, the suction tools 92a to 92d are brought into contact with the inner surface in the width direction with respect to the front edge of the front end of the transported object C1, and the bowl-shaped portions of the suction tools 92a to 92d are in close contact with the transported object C1. And deformed. The suction tools 92a to 92d suck and hold the front surface of the transported part C1 at the foremost end with a negative pressure generated by a vacuum pump (not shown). Next, the suction tool 92a is swung from the approach position to the separation position in the separation direction (FIG. 5C). In other words, in a state where the suction tool 92 sucks and holds the front surface of the transported object C1 at the foremost end, the suction tool 92a extends in the width direction from the one edge where the transported object is regulated toward the other edge which is not regulated. It can be moved. As a result, the distance between the suction tool 92a and the one-side edge regulating upper surface 28 of the first support member 18 is shortened, whereby the suction tool 92a sucks and holds the portion to be transported C1 and the first support member 18. Since the distance to the one side edge RL regulated by the one side edge regulating upper surface 28 is shortened, the conveyed object C1 is compressed and a part thereof is curved and protrudes forward, and the conveyed object C1 at the foremost end, Is separated from the conveyed object C2 located immediately after (that is, second from the front). At this time, as will be described later, the other end edge restricting piece 102a is protruded to the projecting position so as to face the other end edge of the conveyed object C1, and the movement of the conveyed object C1 outward in the width direction is reliably restricted. Therefore, a part of the object to be conveyed C1 is surely protruded forward and separated from the object to be conveyed C2. Thereafter, the suction tools 92a to 92d are moved back and forth from the forward position to the backward position while maintaining the state of the separation position in the separation direction (FIG. 5D). At this time, since the transported object C1 and the transported object C2 are reliably separated in the state shown in FIG. 5C, the suction tools 92a to 92d reliably secure only the transported object C1 at the foremost end. Can be detached from the front edge portion regulating means 3, that is, carried out from the support means 2. Thereafter, as shown in FIG. 5 (e), the suction tools 92a to 92d move laterally from the holding position to the discharge position in the left-right direction while maintaining the state of the separation position in the separation direction, and the suction operation state is in this position. Is switched to the suction inactive state. Thus, the conveyed object C1 sucked by the suction tools 92a to 92d is transferred to an appropriate feeding means 124 such as a nip roller indicated by a two-dot chain line, and the conveyed object C1 is released. After the transported object C1 is discharged, the suction tools 92a to 92d move sideways from the discharge position to the holding position in the left-right direction while turning from the separation position to the approach position in the separation direction, and again in FIG. 5 (a). It becomes the reference state shown.

  When the transported object carrying-out means 4 operates as described above, the other end that comes into contact with the front surface of the transported object C1 at the foremost end as understood by referring to FIGS. The edge regulating piece 102 is pushed in the carrying direction by the foremost object C1 to be moved to the retracted position, and the other end edge regulating piece 102 that does not contact the front surface of the foremost object C1 is free as described above. It is projected to the protruding position by dropping. However, since the other end edge regulating piece 102a located adjacent to the outer side in the width direction of the foremost object C1 is not in contact with the front surface of the foremost object C1, it is protruded to the protruding position. Opposite to the other end edge of the object to be conveyed at the front end including the object to be conveyed C1 at the front end, the object to be conveyed at the front end is restricted from moving from one end edge to the other end in the width direction. The

  Therefore, according to the first aspect of the present invention, the other end edge regulation located adjacent to the outer side in the width direction of the object to be conveyed at the front end regardless of the length of the side edge of the object to be conveyed. Since the piece 102 is located at the protruding position and is opposed to the other end edge of the object to be conveyed at the front end, the object to be conveyed at the front end is moved from the one end edge to the other end edge by the operation of the object unloading means 4. Even when the length of the side edge of the object to be conveyed is changed to a different one, there is no need to perform a relatively complicated manual operation.

  When the transported object carrying-out means 4 operates as described above, as will be further understood by referring to FIGS. 5, 6, and 9, the one side edge of the transported object at the front end is one side. The one-side edge engaging means 8 disposed on the edge regulating upper surface 28, more specifically, the upper edge of the inner side surface 116 (engagement surface) that faces the one edge regulating inner surface 36 and sharply stands upward toward this one. Engagement is limited, and the object to be conveyed at the front end is restricted from moving from the one end edge toward the other end in the width direction. Although one side edge of the conveyed object is a straight edge, it is uneven when viewed microscopically, and the above-described engagement is established by the upper edge of the inner side surface 116 that is sharply cut off from the unevenness being caught.

  Therefore, according to the second aspect of the present invention, regardless of the length of the side edge of the conveyed object to be conveyed, the one side edge of the conveyed object at the front end is directed upward toward the one edge regulating inner surface 36. Since it is engaged with the sharply cut inner side surface 116 (engagement surface), the object to be conveyed at the front end moves in the width direction from one edge to the other edge by the operation of the object to be conveyed unloading means 4. However, even when the length of the side edge of the object to be conveyed is changed to a different one, there is no need to perform a relatively complicated manual operation.

  The back plate 12 and the transport stand 14 are moved forward integrally when the detection switch 38 provided on the upstream surface in the transport direction of the front edge edge regulating means 3 is opened, and transports the transported object C forward to detect it. It stops when the switch 38 is closed. The detection switch 38 is closed by abutting against the transported object C1 at the front end and being pressed with a predetermined pressing force. However, the detection switch 38 is closed when the back plate 12 and the transport stand 14 are applied with a predetermined pressing force by the back plate 12 to the object C to be transported between the back plate 12 and the front end edge regulating means 3. Then, when one or a plurality of the objects to be conveyed C are unloaded by the above operation of the object to be conveyed unloading means 4, and the object to be conveyed C between the back plate 12 and the front edge portion regulating means 3 decreases. The pressing force is reduced and the detection switch 38 is opened and moves forward again. Then, when the back plate 12 and the transport stand 14 move forward and a predetermined pressing force is applied to the object C to be transported between the back plate 12 and the front surface edge edge regulating means 3, the detection switch 38 is closed. It will stop again. Here, as described above, the movement of the front end portion in the width direction of the object to be conveyed is limited by the one-side edge engaging means 8, but the movement in the forward direction (conveyance direction) is such that the ridge line 120 is straight in the conveyance direction. It is not limited because it extends in the shape, and the object C is advanced by the operation of the back plate 12 and the transfer stand 14 as described above.

  When the back plate 12 and the transport stand 14 advance from the respective backward action positions shown in FIG. 12-1 (a) to the respective forward action positions shown in FIG. 12-1 (b), the back plate 12 advances from the forward action position. It moves to the non-acting position (FIG. 12-1 (c)), then moves to the retracting non-acting position (FIG. 12-2 (d)), then moves to the retracting action position, and the holding member 16 (ie, The holding piece 74) moves from the non-operating position to the operating position (FIG. 12-2 (e)). This movement of the holding member 16 may be performed while the back plate 12 moves from the forward acting position to the backward acting position or after the movement is completed. In the state shown in FIG. 12-2 (e), the back plate 12 and the partition piece 60 at the foremost end of the transport stand 14 match in the transport direction, but as will be understood by referring to FIG. Since the plate pieces 50a to 50e constituting the back plate 12 and the partition pieces 60a to 60c located at the forefront end of the transport stand 14 are different in the width direction, the plate pieces 50a to 50e and the partition pieces 60a to 60c are mutually connected. There will be no interference. Similarly, the holding pieces 74a to 74d and the partition pieces 60a to 60c of the transport stand 14 match in the transport direction, but the holding pieces 74a to 74d and the partition pieces 60a to 60c of the transport stand 14 are positioned in the width direction, respectively. Since they are different, the holding pieces 74a to 74d and the partitioning pieces 60a to 60c do not interfere with each other. After the holding member 16 has moved from the non-operating position to the operating position, the transport stand 14 moves from the forward operating position to the forward non-operating position (FIG. 12-2 (f)), and then moves to the reverse non-operating position (FIG. 12). 12-3 (g)), and then moves to the retracting position (FIG. 12-3 (h)). Then, after the transfer stand 14 has moved to the retracting action position, the holding member 16 moves from the action position to the non-action position (FIG. 12-3 (i)). During the above movement of the back plate 12, the transport stand 14 and the holding member 16, the transported object unloading means 4 continues to transport the transported object C supported by the first support member 18.

  The state shown in FIG. 12-3 (i) and the state shown in FIG. 12-1 (a) are the partition piece 60 located at the transport direction rearmost end of the transport stand 14 and the partition located adjacent to the front thereof. Only the presence or absence of the object to be conveyed C in the region between the pieces 60 is different, but the other states are the same, and the object to be conveyed C can be continuously conveyed by repeating the above operation. Moreover, it becomes possible for an operator to continue transporting the transported object C continuously for a long period of time by replenishing the transported object C with a new transported object C in the above-described area where the transported object C is free.

  Although the carrying-out apparatus 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 embodiments, and various modifications and corrections can be made without departing from the scope of the present invention. is there. For example, in this embodiment, since the first support member is inclined in the width direction, the one-side edge regulating upper surface is inclined, but instead, the first support member is horizontal and the one side is The edge regulating upper surface may also be substantially horizontal. Furthermore, in the present embodiment, the first support member is constituted by a single flat plate, and a groove is formed in the flat plate. Instead, a plurality of flat plates extending in the transport direction are arranged in the width direction. The grooves may be arranged so as to be defined between the flat plates adjacent in the width direction.
