  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  A description will be given based on the case where the seedling (nursery seedling box) grown in the greenhouse 22 is the transported object 1 and the seedling box 1 is loaded on the vehicle 19 for transferring to the rice field.

  For example, at least the distal end portion of the transport device 2 is disposed in the greenhouse 22, and the base end side support portion 4 on which the shaft support mounting portion 3 on the base end side of the transport device 2 is pivotally supported via the shaft support portion 5 is made of vinyl. Arranged in the vicinity of the transfer vehicle 19 stopped outside the house 22.

  Then, the protruding distal end portion of the conveying device 2 that inclines and tilts from the distal end side toward the proximal end side is disposed so as to be lower than the proximal end portion and closer to the ground surface than the proximal end portion.

  The nursery box 1 laid side by side on the ground contact surface in the greenhouse 22 is transported one after another in the vicinity of the protruding tip of the transport device 2 disposed close to the ground contact surface while the operator bends and leans. The seedling box 1 that can be placed on the distal end side of the apparatus 2 is transported to the proximal end side of the transport apparatus 2 (near the transfer vehicle 19).

  Therefore, the operator can continuously perform the work of placing the seedling box 1 on the transport device 2 with the waist bent, so that the work to the transport device 2 can be performed as compared with the work that requires bending and stretching the waist. The loading operation can be performed remarkably easily.

  At this time, since the leading end side of the conveying device 2 is disposed so as to protrude from the intermediate support portion 6, the leading end portion of the conveying device 2 is positioned closest to the present apparatus side in the greenhouse 22. As shown in FIGS. 1 and 6 instead of the position in front of the seedling box 1, the leading end portion of the transport device 2 can be arranged at a position farther from the seedling box 1 positioned at this end. Therefore, if it is the structure which can arrange | position the front-end | tip part of the conveying apparatus 2 only in the position before the seedling box 1 located in an end, the seedling box 1 and the front-end | tip part of the conveying apparatus 2 as the seedling box 1 is loaded. However, according to the present invention, the loading operation is performed in a state where the seedling box 1 is placed around the middle of the transport device 2. Since the operation can be started, the operator can load a large number of seedling boxes 1 with little movement around the front end of the transfer device 2.

  In addition, once the installation position of the apparatus is determined, the work can be performed without moving the position of the apparatus up to the seedling box 1 up to the far side of the greenhouse 22, and the apparatus can be further installed in the greenhouse. 22 When moving to the back side, since the tip of the transport device 2 can be placed on the back side at the stage of the first placement, it is necessary to place it on the back side in this way. Thus, the moving distance to the back side of the greenhouse 22 required until the end of the operation of the present apparatus is reduced.

A large number of seedling boxes 1 can be placed on the transport device 2 with the transport device 2 directed (turned) over a wide range without moving the device itself.

  Further, for example, if a turning guide mechanism 7 for guiding the turning movement of the transport device 2 relative to the intermediate support portion 6 is provided in the intermediate support portion 6 or in the middle of the transport device 2, the transport device 2 can be smoothly and The workability is further improved because it can be reliably turned.

  Further, for example, a receiving unit 12 for the object to be conveyed 1 is set at a base end position of the transporting device 2 or a position transported from the base end of the transporting device 2, and whether or not the transported object 1 exists in the receiving unit 12. When the receiving unit detecting device 13 detects that the transported object 1 of the receiving unit 12 has been removed, the transport driving is resumed, and the next transported object 1 is detected. If the conveyance control unit configured to stop the conveyance drive when it is detected that the item is conveyed to the receiving unit 12 is provided, the receiving unit 12 does not receive the object to be conveyed 1 (nurturing box 1). Since the transport drive is not resumed, it is possible to reliably prevent malfunctions in which the transported object 1 is successively transported to the receiving unit 12 even though the transported object 1 is not received by the receiving unit 12. So it becomes more practical.

  Further, for example, a placement unit 14 for placing the article to be conveyed 1 is set at the position of the leading end of the conveying device 2 or a position where it can be conveyed to the leading end of the conveying device 2. 1 is provided. When the placement part detection device 15 detects that the article 1 is placed on the placement part 14, the carriage drive is started. When it is detected that the transported object 1 has disappeared from the loading unit 14 by this transport, or a predetermined time has elapsed from the start of the transport, or the transported object 1 has been transported to a predetermined position, the transport driving is stopped. If the configured transport control unit is provided, the objects to be transported 1 can be placed in order on the transport device 2 at regular intervals, so that the placement space of the transport device 2 can be used effectively and efficiently. The transported object 1 can be transported and becomes more practical.

  Further, for example, a placement unit 14 for placing the article to be conveyed 1 is set at the position of the leading end of the conveying device 2 or a position where it can be conveyed to the leading end of the conveying device 2. 1 is provided. When the placement part detection device 15 detects that the article 1 is placed on the placement part 14, the carriage drive is started. When it is detected that the transported object 1 has disappeared from the loading unit 14 by this transport, or a predetermined time has elapsed from the start of the transport, or the transported object 1 has been transported to a predetermined position, the transport driving is stopped. And a receiving unit 12 for the object to be conveyed 1 is set at a base end position of the conveying device 2 or a position conveyed from the base end of the conveying device 2, and the presence or absence of the object to be conveyed 1 is set in the receiving unit 12. A receiving unit detecting device 13 for detecting the receiving unit 12 by the receiving unit detecting device 13. The conveyance drive is resumed when it is detected that the delivery 1 has been removed, and the conveyance drive is stopped when it is detected that the next object to be conveyed 1 has been conveyed to the receiving unit 12. If the transported object 1 is transported to the receiving unit 12, a transport control unit configured to stop the transport drive regardless of the presence or absence of the placement unit 14 unless the transported object 1 is removed is provided. Since the objects to be conveyed 1 can be placed one by one in order on the conveying device 2 at regular intervals, the objects to be conveyed 1 can be efficiently conveyed by effectively using the loading space of the conveying device 2. In addition, since the transported object 1 is not received by the receiving unit 12, it is possible to reliably prevent malfunctions such that the transported object 1 is transported to the receiving unit 12 one after another. It will be excellent.

  In addition, the placement unit 14 is the receiving unit 14 at the time of reverse rotation and the receiving unit detector 15 is the receiving unit detection device 15 at the time of reverse rotation. The reversing drive is restarted by the receiving unit detecting device 15 and the transporting is performed so that the reverse driving is stopped by the receiving unit detecting device 15 for reverse rotation when the next conveyed object 1 is transported to the receiving unit 14 for reverse rotation. If a control part is comprised, the conveyance apparatus 2 can be reversely driven, and it can also be made easy to arrange the to-be-conveyed object 1 on the ground conversely, for example. That is, the reverse operation can be performed smoothly and efficiently.

  Further, in this embodiment, the placement unit 14 for placing the article 1 to be transported is set at the position of the tip of the transport device 2 or the position where the transport device 2 can be transported to the tip of the transport device 2. A placement unit detection device 15 that detects the presence or absence of the transported object 1 is provided. When the placement unit detection device 15 detects that the transported object 1 is placed on the placement unit 14, the transport drive is performed. The transport drive is stopped when it is detected that the transported object 1 has disappeared from the placement unit 14 by this transport, or a predetermined time has elapsed from the start of the transport, or that the transported object 1 has been transported to a predetermined position. The conveyance control part comprised so that it may be provided.

  Specifically, the upper surface position of the front end portion of the transport device 2 is set to the placement portion 14, and a limit switch 15 as a placement portion detection device 15 is provided on the placement portion 14. The limit switch 15 employs a hoisting operation switch that is always urged to an activated state. When the limit switch 15 is activated, the drive source 2D stops and stops the conveyance drive, and when the limit switch 15 activates, the drive source The conveyance control unit controls the 2D so that the conveyance drive is performed.

  Further, the limit switch 15 is mounted and fixed so as to protrude upward from the endless belt 2B of the placing portion 14 in the biased activation state. When the article 1 is placed on the placing portion 14, the limit switch 15 is conveyed. The bottom surface of the object 1 comes into contact with the limit switch 15, and the limit switch 15 is pressed down by its own weight to start the conveyance drive. By this conveyance drive, the object to be conveyed 1 is moved from the loading section 14 to the base end side of the conveyance device 2. When the object is moved (when the object to be conveyed 1 disappears from the limit switch 15), the limit switch 15 is automatically energized and the conveyance drive is stopped.

  That is, by this drive control, the objects to be conveyed 1 can be placed one by one on the conveying device 2 in an orderly manner without any gaps, so that the placement space of the conveying device 2 can be used effectively and efficiently. The to-be-conveyed object 1 can be conveyed.

  Further, a switch (not shown) for turning on / off driving control advantageous for loading work by the limit switch 15 and the transport control unit is provided on the front end side of the transport device 2, and this switch is provided on the front end side of the transport device 2. It is configured so that the loading worker T who works can easily turn on and off.

  Further, in this embodiment, when both the drive control switch that favors the loading operation and the drive control switch that favors the receiving operation are turned on, the conveyed object 1 is conveyed to the receiving portion 12. As long as the transported object 1 is not removed, the transport control unit is driven and controlled so as to stop the transport drive regardless of the presence or absence of the transported object 1 in the placement unit 14.

  The integrated working apparatus of the present embodiment configured as described above is not structurally complicated and can be easily designed and realized, and can provide an inexpensive product with excellent mass productivity.

  Next, a method for using the stacking work apparatus of this embodiment will be described. In this embodiment, a seedling (nurturing box) grown in the greenhouse 22 is used as a transported object 1 (hereinafter referred to as a seedling box 1), and a vehicle 19 for transferring the seedling box 1 to the rice field (for example, This is a case where the present apparatus is used for loading into the container 21 of the loading platform of the light truck 19).

  This apparatus is grounded so that the intermediate support portion 6 is in a temporary state on the seedling box 1 placed at the end in the greenhouse 22. In addition, the vehicle 19 is stopped in the vicinity of the apparatus so that the base end side support portion 4 (receiving portion 12) and the container 21 placed on the loading platform of the vehicle 19 are as close as possible (FIG. 1, FIG. 1). (See FIG. 6.)

  Then, the protruding distal end portion of the conveying device 2 that is inclined upward from the distal end side toward the proximal end side is disposed so as to be lower than the proximal end portion and closer to the ground surface than the proximal end portion. The protruding tip of the transfer device 2 is placed in a floating state above the nursery box 1 on the back side of the greenhouse 22 rather than on the seedling box 1 at the end where it is placed.

  For example, both the drive control switch that favors the loading operation and the drive control switch that favors the receiving operation are turned on in advance.

  The nursery box 1 laid side by side on the ground surface in the greenhouse 22 with the posture where the loading worker T bends and bends in the vicinity of the protruding tip of the transport device 2 arranged in a state close to the ground surface. The seedling box 1 placed on the transport device 2 can be placed one after another from the end on the placement portion 14 on the front end side of the transport device 2, and the seedling box 1 placed on the transport device 2 moves to the base end side of the transport device 2 (near the transfer vehicle 19). Will be transported.

  Further, at this time, since the conveying device 2 can be moved in the horizontal direction while being moved with respect to the intermediate support portion 6 with the shaft support portion 5 as a fulcrum, it can be conveyed over a wide range without moving the device itself. A large number of seedling boxes 1 can be placed on the transport device 2 with the device 2 facing (turned). Although not shown in the figure, the conveyance device 2 may be provided with a handle for turning operation.

  Accordingly, the loading worker T can continuously perform the work of placing the seedling box 1 on the transfer device 2 with the waist bent, so that it is necessary to bend and stretch the waist once at a time as before. Compared to the work, the work can be performed remarkably easily.

  At this time, when the seedling box 1 is placed on the placement unit 14, as shown in FIGS. 8 and 10, the limit switch 15 is bent down by the dead weight of the seedling box 1, and the conveyance driving is started. When the seedling box 1 is moved from the placement unit 14 to the transport device 2 base side by driving and the seedling box 1 disappears from the limit switch 15, the limit switch 15 is automatically activated to stop the transport drive. The objects to be conveyed 1 can be placed in order on the conveying device 2 without leaving a large gap. Therefore, the seedling box 1 can be efficiently transported by effectively using the placement space of the transport device 2. In the present embodiment, a maximum of 11 seedling boxes 1 can be placed on the transfer device 2 (12 pieces including those placed on the receiving section 12).

  Further, when the seedling box 1 placed first moves to the base end of the transporting device 2, it is transported to the receiving part 12 as shown in FIGS. 9 and 10, and the limit switch 13 is caused by the weight of the seedling box 1 itself. Is depressed and the conveyance drive is stopped. In this state, the conveyance control unit controls the driving so as to stop the conveyance drive regardless of the presence of the seedling box 1 of the placement unit 14 unless the seedling box 1 conveyed to the receiving unit 12 is removed. No seedling boxes 1 are transported one after another to 12 and fall onto the ground surface.

  When the receiving worker U is waiting on the receiving unit 12 side, the limit switch 13 is automatically energized when the conveyed object 1 is removed from the receiving unit 12 and loaded into the container 21 of the loading platform of the vehicle 19. The transfer is started and transport driving is resumed, and the next seedling box 1 is transported to the receiving part 12 and the seedling box 1 can be further placed on the placing part 14 on the leading end side of the transporting device 2.

  This work can be performed by one person.

  That is, after carrying out the loading operation on the transfer device 2 at the front end side of the transfer device 2 until the nursery box 1 cannot be loaded on the transfer device 2, the transfer device 2 moves to the base end side of the transfer device 2 and moves from the receiving unit 12 to the seedling box 1 is loaded on the container 21 of the vehicle 19 one after another, and when all the loading is completed, the work can be performed alone by moving again to the front end side of the transfer device 2 and repeating the above work.

  Further, in the case of the present embodiment, the seedlings are arranged such that the tip of the transport device 2 is arranged at the end in the greenhouse 22 by arranging the tip of the transport device 2 in a protruding state from the intermediate support portion 6. As shown in FIGS. 1 and 6, the tip of the transport device 2 can be disposed not only in the position in front of the box 1 but also in the back side, so that the seedlings are raised around a substantially middle portion of the transport device 2. The loading operation can be started in a state where a large number of boxes 1 are placed, and for a while, the operator loads almost a few seedling boxes 1 around the tip side of the transport device 2 with little movement. In addition to this, it is possible to load a considerably wide variety of seedling boxes 1 by turning the conveying device 2.

  Moreover, once the installation position of the apparatus is determined, the work can be performed without moving the position of the apparatus unless the nursery box 1 up to the back side of the greenhouse 22 is taken out.

  When all the seedling boxes 1 near the front end of the conveying device 2 have been loaded, this device is further moved to the back side of the greenhouse 22 and the above operation is performed.

  Further, the moving distance for moving this apparatus to the back side of the greenhouse 22 by the end of the work is also small because the leading end of the transport device 2 is arranged at the back side at the stage where the apparatus is originally arranged. The travel distance will suffice.

  Therefore, for example, 96 seedling boxes 1 can be loaded into the container 21 to be loaded on the loading platform for the light truck 19, and when performing the operation of picking up the seedling box and loading it into the container 21 as in the past, It is necessary to make 96 round trips between the light truck 19 and the nursery box 1 placed on the ground in the greenhouse 22 until the container 21 is full, and each round trip involves bending and stretching the waist. However, according to the present embodiment, a maximum of 12 seedling boxes 1 can be placed on the transport device 2 and the receiving unit 12, so even if it is a work alone. It is also possible to complete the work by reciprocating only 8 times between the front end side and the base end side of the transport device 2, and the work time can be remarkably shortened. Further, the loading operator T at the front end side of the transfer device 2 can load the nursery box 1 in a posture with the waist bent, and the receiving worker U at the base end side (receiving portion 12) of the transfer device 2. Can work in an upright position, so it is very easy to work in any of these positions.

  Further, when the operation is performed with only the drive control switch advantageous for the loading operation being turned on, the seedling boxes 1 can be successively conveyed to the receiving unit 12 even if the seedling box 1 of the receiving unit 12 is not removed. Therefore, it is necessary to perform work while paying attention to whether or not the seedling box 1 has been transported to the receiving unit 12. When working alone, it is desirable to turn on a drive control switch that is advantageous for at least this loading work from the viewpoint of work efficiency.

  Further, when the operation is performed with only the drive control switch advantageous for the receiving operation being turned on, it is difficult to order the seedling box 1 on the transfer device 2 without a large gap, and it is slightly inefficient. Since the next nursery box 1 is not transported to the receiving part 12 unless the nursery box 1 of the part 12 is removed, it is possible to work without worrying about the fall of the nursery box 1 from the receiving part 12 it can.

  Further, in addition to the first embodiment, in this embodiment, a mode switch capable of reversely driving the object to be conveyed 1 is provided, and conveyed downward from the track 19 to the ground. The transported objects 1 can be easily arranged on the ground while the transported objects 1 are removed from the ground.

  That is, the placement unit 14 described above is the receiving unit 14 at the time of reverse rotation, and the mounting unit detection device 15 is the receiving unit detection device 15 at the time of reverse rotation. The reversing drive is restarted by the receiving unit detecting device 15 and the transporting is performed so that the reverse driving is stopped by the receiving unit detecting device 15 for reverse rotation when the next conveyed object 1 is transported to the receiving unit 14 for reverse rotation. The control unit is configured.

  Accordingly, the transport device 2 can be reversed by pressing the reverse drive mode switch to reversely arrange the transported objects 1 on the ground, for example, so long as the transported object 1 in the reverse receiving portion 14 is not removed. Since the drive is not resumed, the transported object 1 is not yet received by the receiving unit 14 at the time of reverse rotation, but it is possible to reliably prevent malfunctions such that the transported object 1 is successively transported to the receiving unit 14 at the time of reverse rotation. The integrated working device has a configuration excellent in practicality.
