Hereinafter, the present invention will be described in more detail with reference to the drawings.
FIG. 1 is an explanatory diagram showing the configuration of the spreader of the present invention. In the figure, (a) is a cross-sectional view in front view with the processing flow direction before and after the spreading process of the standard product being the spreading process as the left-right direction, (b) is a right side view of (a), In the processing flow, it is a view seen from the front end surface. The same applies to (a) and (b) in FIG. In addition, in the present drawing and each of the following drawings, the components used for the description are merely conceptual diagrams or examples. Therefore, for example, the installation positions and installation modes of the control means and the support units are not limited to those shown in the drawings, and the mode of the stackable body M that can be processed is not limited including the number of stages and the number of arrangements.

  As shown in the figure, the stacking device 1 of the present invention is a device that separates a stacked body M, which is a set of standard products C stacked in a plurality of stages, in order from the bottom, in units of stages. The standard part C is placed on the placing part 2 that is controlled to be raised and lowered, the placing part raising and lowering control means 3 that controls the raising and lowering operation of the placing part 2, and the stacked body M A support portion 4 for supporting the portion from the side at a predetermined height position when it is lifted by ascending and waiting for a portion above the support portion; and a support portion control means 5 for controlling the operation of the support portion 4; The upper surface of the mounting portion 2 is the lower end position of the lowermost standard product C supported directly by the support portion 4 of the stacked body M (first level. Reference numeral “P” in FIG. 2D and the like). Can be raised until the upper surface of the mounting portion 2 reaches the first level. To be controlled by the support unit control means 5 so as to release the support, a predominant constituent.

  The support part 4 of the apparatus 1 is the second standard from the bottom when it comes down to the position of the support part 4 when the placing part 2 picks up the lowest standard C and descends by one stage together with the stacked body M. It is set as the structure controlled by the support part control means 5 so that the thing C may be supported from a side.

  With such a configuration, in the present stacking apparatus 1, the stacking body M is mounted on the mounting unit 2 and is placed on standby by the mounting unit lifting / lowering control means 3 while waiting for the stacking process. Part 2 is first raised. Since the upper surface of the mounting portion 2 can be raised to the first level, which is the lower end position of the lowermost standard product C that is directly supported by the support portion 4 in the stacked body M, the mounting portion is raised and lowered. It is raised to the first level by the operation of the control means 3.

  The support part 4 is configured to release the support for the standard C when the upper surface of the placement part 2 reaches the first level by the operation of the support part control means 5, but in the initial state of the process, As a matter of course, since the standard product C already supported is not present, the stacked body M can pass through the support portion 4 installation position without being stopped by the support portion 4.

  The placement unit 2 that has reached the first level is then lowered with the stacked body M placed thereon by the operation of the placement unit elevating control means 3. When the mounting portion 2 is lowered by one step together with the stacked body M and reaches a position one step lower (second level, indicated by “S” in FIG. 2E, etc.), it descends to the support portion 4 position. The second standard product C from below is supported from the side by the support part 4 by the operation of the support part control means 5. That is, due to the action of the support portion 4, the portion above the support portion of the stacked body M, that is, the portion above the standard product C at the second level from the bottom of the stack body M is in the subsequent movement of the mounting portion 2. Regardless, it is supported at that position and made to wait.

  Thereafter, the placement unit 2 is further lowered by the operation of the placement unit elevation control means 3. At this time, since the standard product C of the second level from the bottom of the stack M is supported at that position by the support unit 4, the mounting unit 2 has the standard product at the lowest level of the original stack M. C is in a state where it is placed, and the placement unit 2 is lowered to the initial height position where a series of spreading process is started by the operation of the placement unit lifting control means 3.

  In this way, the standardized product C that has been subjected to the spreading process remains on the placement unit 2, and the standardized product C is removed from the placement unit 2 and is subjected to subsequent processing.

  The placing part 2 in a state where the standardized product is removed and nothing is placed is raised again by the operation of the placing part raising / lowering control means 3, and reaches the first level which is the highest position where it can be raised. As a result, the original lowermost stage is in a position immediately below the standard product C forming the new lowermost stage of the stacked body M after the spreading process. At this time, the control of the position of the placement unit 2 may be a control in which the placement unit 2 is in contact with the standard product C in the lowermost stage, or a control in which the placement unit 2 is in a state directly below without being in contact.

  The support unit 4 is released from the support for the standard product C by the operation of the support unit control means 5 based on the fact that the upper surface of the mounting unit 2 has reached the first level. As a result, the entire stacked body M including the standard product C at the lowest stage of the stage is placed in a form that is greeted by the placement unit 2. Thereafter, the placement unit 2 is lowered together with the loaded stacked body M by the operation of the placement unit elevating control means 3.

  When the mounting part 2 reaches the second level, the support part 4 supports the standard product C in the second stage from the bottom of the stacked body M, and the subsequent processing proceeds as described above. This process is repeated, and the stacked body M, which is a set of the standard products C stacked in a plurality of stages, is separated in units from the bottom in order, that is, is subjected to a spreading process.

  In the above explanation and the explanation to be described later, the unit / stage unit to be processed is described as “standard product”. However, the unit may be a single standard product (container, pallet, etc.). Moreover, a plurality of standard products may be used. Further, in the case of a plurality of units, a state in which a plurality of steps are stacked may be used as the unit of steps. Further, a plurality of rows may be arranged in the horizontal direction. Further, a state in which a plurality of rows are arranged in a horizontal direction and stacked in a plurality of steps may be set as a unit of steps. The present invention includes both of them.

  In addition, when the upper surface of the mounting portion 2 is lowered from the first level to the second level, the lowering operation is temporarily stopped at the second level, and the support of the second standard product C from the bottom is supported. It is good also as a structure controlled by the mounting part raising / lowering control means 3 so that it may descend | fall again after being made reliably.

  In the case of such a configuration, the placement unit 2 is lowered by the operation of the placement unit raising / lowering control means 3, and when the upper surface thereof is lowered from the first level to the second level, it is once lowered at the second level. The operation is stopped, and after the second standard product C is supported from the bottom by the support portion 4, it is lowered again. By adopting such a configuration, the stack M to be kept on standby is reliably left above, and only the lowest stage unit is reliably placed on the placement unit 2 to realize a safe and reliable spreading process. be able to.

  When the mounting unit lift control means 3 raises the mounting unit 2 in a state where the stacked body M is mounted, the determination to execute the lifting operation is detection of a specific weight at a specific position of the mounting unit 2, stacking By using appropriate detection means such as detection that the body M or a part of the body M exists at a specific spatial position, it can be automatically achieved.

  Similarly, the control by which the mounting unit lifting / lowering control means 3 stops the rising of the mounting unit 2 at the first level or temporarily stops at the second level also sets the height position of the mounting unit 2 or the like. It can be automatically performed by using an appropriate detection means such as detecting or detecting the weight applied to the mounting portion 2.

  Similarly, the support unit control means 5 controls the support of the support unit 4 and the releasing operation thereof, such as the height position of the mounting unit 2, the height position of a predetermined position of the stacked body M to be mounted, and the like. By using a detecting means for detecting, it can be automatically performed. The operation of the support unit 4 when the upper surface of the mounting unit 2 is located at the second level is not simply based on the detection of the height position of the mounting unit 2, but the mounting unit 2 descends from above, for example. Control may be configured such that the support unit 4 is activated when the level is lowered from the first level to the second level by means such as detecting the incoming movement.

  In addition, the specific structure of the support part 4 will not be specifically limited if this can be supported from the side with respect to a specification thing and the part more than the support location can be hold | maintained in the air. For example, a hook structure that can be locked, such as a claw, can be suitably used. That is, it is a structure that is rotated from the side and supported from below the standard C. The hook structure may be a shape / structure that matches the shape / structure of the standard to be applied. Moreover, you may make it the structure which can be replaced | exchanged by preparing the support part of the hook structure matched with each specification which should be applied as an attachment.

  As a specific structure of the support portion 4, a grip structure that matches the side shape, side surface structure, etc. of a standard to be applied may be used. Or it is good also as a press body which can carry out pressure support of a standard thing from the side. In addition, all conventionally known means that can be used as the support portion are within the scope of the present invention. As is apparent from the fact that the structure of the support part 4 includes a hook structure that can be supported from below, the support from the side in the support part of the present invention means that the support part is on the side of the stacked body M. It is not meant that the force must be applied strictly from the side direction.

  In addition, in the present apparatus 1, a housing structure 8 is provided above the mounting portion 2, and a guide (not shown) that guides and supports the stacked body M that is raised and waited in the vertical direction is provided inside. It is desirable to make it. By doing so, it is possible to effectively prevent the collapse of the stack M that is waiting upward, to make the device operate smoothly, to ensure the safety of the surroundings even in the event of a collapse of the load, It is because the smooth raising / lowering operation | movement of the mounting part 2 and the stacked body M is obtained.

  In FIG. 1, the device 1 of the present invention can be configured such that the placing unit 2 has a structure of a conveyance path for horizontally moving the stacked body M and the standardized product C after being separated. Furthermore, it is possible to adopt a configuration provided with a transport path travel control means 6 for controlling the travel / stop of the transport path. As the transport path structure, an endless belt, a so-called belt conveyor can be suitably used.

  The conveyance path traveling control means 6 moves the stack M up and waits while the raising / lowering control of the placing part 2 by the placing part raising / lowering control means 3 is performed, The travel of the transport path is stopped until only the standard product C is loaded or lowered and returned to the initial height position. In other cases, the travel and stop can be freely controlled. Shall be composed.

  FIG. 2A to FIG. 2M are diagrams for explaining a leveling process performed by the leveling device 1 of the present invention having such a conveyance path structure. In each figure, the operating control means is indicated by a double framed square. Further, the support portion 4 during the support operation is displayed as a thick-line square hatched with a horizontal line.

  The stacked body M has been transported by being placed on the mounting portion 2 of the transport path structure that is operated by the transport path travel control means 6 (FIG. 2A), and when it reaches a predetermined position in the apparatus 1, appropriate detection is performed. The stop control by the conveyance path traveling control unit 6 is performed by the unit, and the placement unit 2 stops traveling (FIG. 2B). The placement unit 2 is at an initial height position. Here, the placing part lifting control means 3 starts to operate.

  By the raising control by the placing part raising / lowering control means 3, the placing part 2 that has already stopped traveling rises with the stacked body M placed thereon (FIG. 2C). At this time, since the support portion 4 is in a released state, there is no hindrance to the ascending operation of the stacked body M.

  The upper surface of the mounting portion 2 is raised to the first level P that is the highest point of rise (FIG. 2D). When the upper surface of the mounting portion 2 is at the first level P, the support portion 4 is configured to be released from the support operation by the support portion control means 5, but the support portion 4 is originally stacked in the illustrated stage. The body M (standard product C) is not laterally supported.

It should be noted that the height of the housing structure 8 is the same as that when the upper surface of the mounting portion 2 is positioned at the first level P in the state where the stack M of the limit height is mounted on the mounting portion 2. What is necessary is just to be designed to such an extent that the accommodation of the stack M is not hindered.

  The placement unit 2 that has reached the first level P is lowered by the placement unit elevation control means 3 while the stacked body M is placed thereon, and the upper surface of the placement unit 2 has reached the second level S. At that time, the support part 4 supports a part of the stacked body M from the side by the operation of the support part control means 5 which detects the state by an appropriate detection means and performs control based thereon (FIG. 2E). The part to be supported is a standard product C one level above the lowest level of the stacked body M, that is, the second level from the bottom. As a result, the upper part of the stacked body M excluding the lowermost standard product C is reliably held in the air at the position shown in the figure, and is in a standby state for the stacking process.

  In addition, in the state where the mounting part 2 has reached the second level S, the mounting part 2 is temporarily stopped by the mounting part lift control means 3 in order to ensure the support of the upper part by the support part 4. It is good also as controlling.

  While the upper portion of the stacked body M is reliably supported in the air by the support portion 4, the placement portion 2 is lowered by the control by the placement portion elevating control means 3 (FIG. 2F). On the mounting part 2, only the step unit forming the lowest stage of the original stacked body M or the standard product C is placed.

  The placement unit 2 descends to an initial height position and stops, and the conveyance path travel control unit 6 can start the control here. In the upper air, the stacked body M from which the lowest standard C is separated is held by the support portion 4 and is in a standby state (FIG. 2G).

  The conveyance path structure of the mounting portion 2 is operated by the conveyance path traveling control means 6, and the standardized product C separated from the stacked body M is transferred and discharged from the apparatus 1. In the upper air, the lower standard product C is kept in the state of being held and waiting by the support portion 4 of the stacked body M (FIG. 2H).

  In order to newly welcome the standard C from the lowermost stage of the stacked body M held above, the placing part 2 is raised by the placing part raising / lowering control means 3 (FIG. 2I).

  The mounting portion 2 is allowed to reach the first level P, thereby releasing the support of the stacked body M by the support portion 4 (FIG. 2J). As a result, the entire remaining stack M is placed on the placement unit 2.

  When the mounting portion 2 is lowered by the control of the mounting portion lifting / lowering control means 3 and reaches the second level S, the support portion 4 supports the second standard product C from the bottom (FIG. 2K). ). The operation here is the same as the operation described above with reference to FIGS. 2E and 2F.

  The placement unit 2 is lowered to the initial height position by the placement unit elevation control means 3 (FIG. 2L). Only the standard product C separated from the lowermost stage of the stacked body M is placed on the placement part 2. The conveyance path structure of the mounting portion 2 is operated by the conveyance path traveling control means 6, and the separated standard product C is transferred. In the upper air, the remaining stacked body M is held by the support portion 4 (FIG. 2M).

  When the procedure shown in FIG. 2I and subsequent steps is repeated and all the standard products C constituting the original stacked body M are separated and transferred, that is, when a series of separation processes is completed, FIG. As shown, the next stack M is prepared and processed in a similar procedure.

  FIG. 3 is an explanatory diagram showing a configuration of the present invention spreading device having a stacking unit. As shown in the figure, this apparatus has a stacking structure for forming and / or preparing a stacking body M on the upstream side of the mounting portion 2 having the transport path structure in addition to the above-described components. It can be set as the structure by which the part 9 was provided. It is convenient if the mounting portion of the stacking unit 9, that is, the preliminary mounting unit 92, has a transport path structure so that the formed stack M can be transported to the mounting unit 2. It is.

  The spreading device of the present invention having the above-described configuration can be used for various standards. It is possible to construct a device that meets the specifications, such as containers of various shapes and structures, pallets, flat plates, etc., and it is possible to respond by preparing the support part as an attachment as described above, both of which are within the scope of the present invention.
