Description

  The present invention is a leaf tobacco simple unloading apparatus used when unloading a leaf tobacco suspended from a needle rack from a drying chamber together with a needle rack after completion of a series of drying steps, and is accommodated particularly in a high place. The present invention relates to a simple tobacco leaf taking-out device that can safely and easily take out used leaf tobacco with little effort.

  Conventionally, harvested leaf tobacco requires a drying process in which drying of leaf tobacco is performed in a drying room by controlling the dry bulb temperature and wet bulb temperature by opening and closing the heat source and damper of the burner for about 120 hours. is there.

  And before entering this drying process, it is necessary to suspend the leaf tobacco in the drying chamber. Therefore, a machine called a sewing machine leaf knitting machine sews the thread along the petal portion of the leaf tobacco, and a stick shape called a stick. The method of suspending by the thing was adopted. However, in this method, the sewing machine has to be sewn, which is very troublesome. Further, at the time of this yarn removal, there is a thread unleakage, which requires visual confirmation by an operator, which is very troublesome.

  Therefore, there is a method of mounting a leaf tobacco by planting a large number of needles in a rack and inserting the leaf pattern portion of the leaf tobacco through the needles. To introduce an example, a large number of needles are implanted in the upper frame of the rack, placed so as to mesh with the upper frame and the lower frame, and the leaf tobacco is suspended. The rack is provided with wheels on both side ends, and the rack on which the leaf tobacco is suspended can be moved by rotating on a rail provided in the drying chamber.

  Next, a general drying chamber will be described. The drying chamber has a structure for accommodating a rack for suspending leaf tobacco over a plurality of stages such as two stages in the upper and lower sides or three stages in the upper, middle, and lower in order to effectively use this space. In the longitudinal direction of the drying chamber, it is arranged depending on the shape and size of the drying chamber.

  After the drying process, the racks are unpacked by unpacking the first rack placed near the operator's waist and the second rack placed near the head one by one. It is easy to unload the first level rack placed at the waist level, but the second level rack located at the head level is heavy labor, Since most of the workers are elderly people, the rack for suspending the leaf tobacco has a weight of about 10 kg or more, so it is a very difficult operation and must be carefully performed.

  Furthermore, since it is an unloading work from the height of the head, when it is difficult to work alone, it has been necessary to repeatedly raise and lower the lifting platform one by one through the lifting platform. In addition, when not using the raising / lowering stand at the time of working by two persons, there existed a problem that work efficiency was very bad and work required a long time.

  And the idea regarding the simple taking-out apparatus of a needle rack is disclosed in the drying chamber of this leaf tobacco. One example will be described.

  First, (1) is Japanese Patent Application Laid-Open No. 2004-33184 “Leaf tobacco removal equipment”. According to the present invention, a guide rail is connected to a rail-shaped suspension receiver provided in a drying chamber, and the suspension member that suspends a tobacco leaf is moved downward along the guide rail after the guide rail is tilted forward and downward. The support arm that supports the guide rail is attached to the support arm so that it can rotate. By rotating the support arm, the work is unloaded from the guide rail, and the work efficiency is low and low in labor. It is intended to improve.

  Next, (2) is disclosed in JP-A-5-176742 "Leaf tobacco drying labor saving system". The present invention is configured so that the unloading work after the drying process can be carried out by hanging the dry leaves in the drying chamber into the lifting rack together with the racks and unloading them to a temporary hanging rack near the workbench. To save energy in taking out tobacco leaves.

  An embodiment of the present invention will be described with reference to the drawings.

  First, the drawings of the present invention will be described. FIG. 1 is a perspective view showing an example of the present invention, FIG. 2 is an enlarged perspective view of a lifting mechanism, FIG. 3 is an enlarged perspective view of another example of the present invention, and FIG. FIG. 5 is an enlarged perspective view of still another example of the invention, and FIG. 5 is a perspective view of a picking table showing an example of the present invention.

  Hereinafter, the embodiment of the present invention will be described. The building is provided with a large number of drying chambers 1 to n (in this example, 1). This drying chamber 1 is provided with two upper and lower shelf rails 3 in the longitudinal direction, and this lower shelf rail (not shown) is installed near the position of the operator's waist and the upper shelf rail. 3 is installed in the vicinity of the position of the operator's head.

  Needle racks 4 for holding leaf tobacco are supported in series on the shelf rail 3 on the upper stage, and the leaf tobacco is passed through a damper (not shown) and a burner (not shown) as described above. And the wet bulb temperature is controlled, and the drying process is performed for about 120 hours.

After this drying process is finished, the needle rack 4 is unloaded. At the time of this unloading operation, as will be described later, the leaf tobacco simple unloading device 5 is installed at the opening of the drying chamber 1 to perform the unloading operation. The leaf tobacco is transported to the picking table 20 in the vicinity of the drying chamber 1 shown in FIG. 5 by this unloading operation, and the picking operation of the leaf tobacco is performed on the picking table 20.

  Next, an example of the simple tobacco leaf taking-out device 5 will be described. The leaf tobacco simple unloading device 5 has a base 6 provided with a U-shaped moving means 60 and a fixing means 61 in plan view, and is a rectangular shape standing on the base 6 and having an opening 7a at one end. There is a frame 7. An elevating rail 8 is supported on the frame 7, and is composed of an elevating mechanism 9 that controls the elevating rail 8. The frame 7 is inclined so that when the elevating rail 8 is lowered by the extension of the elevating mechanism 9, the elevating rail 8 can maintain a substantially horizontal state. The base 6 is not only U-shaped in plan view, but can prevent the frame 7 from falling and rolling, and the lifting rail 8 can be lifted and lowered so that the frame 7 can stand upright. , Not limited. For example, in plan view, as described above, various shapes such as a U-shape, a square shape, and an H-shape can be used.

  As described above, one example of the frame 7 (referred to as the number of one side) has been described, but a structure in which several (two) are provided side by side or the apexes of the frame 7 are connected to form a triangular shape. The structure in which the frame 7 is inclined (inclined), such as the structure provided in FIG. 5, has features that it is easy to unload as the elevating rail 8 descends, and can be naturally separated from the drying chamber 1. This is useful for improving efficiency. Further, the frame 7 is not limited to the inclined structure, but a structure in which a vertical frame (not shown) moves on the base 6, and the vertical rail (not shown) is moved up and down and / or A structure that moves in an inclined manner is possible. In addition, the auxiliary frame 700 is provided in a brace shape in order to hold the frame lower portion 10 or the frame 7 (an example of a structure without the frame lower portion “not shown”). By providing this auxiliary frame 700, the frame 7 can be tilted and the elevating rail 8 can be stably moved up and down by the frame 7 in order to prevent the frame 7 from falling and rolling. The auxiliary frame 700 is not limited as long as the frame 7 can be reliably erected.

  Further, the moving means 60 is provided with casters 600 for controlling the movement of the leaf tobacco simple unloading device 5 at the four corners of the base 6, and the fixing means 61 is similarly provided at the four corners of the base 6 with the leaf tobacco simple unloading device 5. An adjuster 610 for controlling the pressure contact and fixing of the ground is provided. The moving means 60 and the fixing means 61 are not limited as long as they are responsible for moving and fixing the leaf tobacco simple unloading apparatus 5.

  Next, an example of the lifting mechanism 9 will be described. The elevating mechanism 9 includes a damper 90 and a link mechanism 91. The link mechanism 91 is formed in a dogleg shape when one end of the link rods 910 and 911 is connected and viewed from the side. The link bar 910 at the lower end is fixed to the frame 7 and the link bar 911 at the upper end, and bears the movement of the link bar 911 and the damper 90 at the upper end moving up and down. This is responsible for the movement of folding or returning the link bar 911 at the upper end due to the contraction or extension of the damper 90. That is, when the needle rack 4 is loaded on the lifting rail 8, a force is applied in the direction in which the damper 90 contracts due to the weight of the needle rack 4 and / or the leaf tobacco, and resistance is generated. By this resistance, the link mechanism 91 is folded slowly while limiting the speed. And the raising / lowering rail 8 supported by this link mechanism 91 descend | falls slowly, maintaining a substantially horizontal state. Similarly, when the needle rack 4 is removed from the lifting rail 8, the damper 90 changes in the extending direction, the lifting rail 8 is raised, and the link mechanism 91 is returned. Hereinafter, this movement is repeated.

  The link rods 910, 911 are U-shaped, and the upper link rod 911 is formed so as to sandwich the lower link rod 910. The link rod 911 may be formed so as to be sandwiched between the link rods 910 below. Furthermore, if the role of a flat link or the like is fulfilled, the shape is not particular.

  Furthermore, a structure in which one end of the damper 90 is fixed to the link rod 910 at the lower end, and the other end is fixed through a support member 710 provided on the frame 7 is also conceivable. Note that the movements of the damper 90 and the link mechanism 91 at this time are the same as described above, and will be omitted.

  In addition to the damper 90 and the link mechanism 91, the lifting mechanism 9 includes a lifting mechanism using wires and pulleys, a lifting mechanism using chains and sprockets, a lifting mechanism using cylinders, a weight and winding motor, and the like. An elevating mechanism or the like is also possible, and the elevating rail 8 is not limited as long as it moves up and down while maintaining a substantially horizontal state.

  Further, the elevating mechanism 9 is supported by the elevating rail 8, and the elevating rail 8 is provided with the opening 7 a in the frame 7 as described above. A trochanter 7b that slides and rotates in a passage 7c in the frame and an axis (not shown) extending from the trochanter 7b are attached to the lifting rail 8 in the opening 7a. The elevating rail 8 moves up and down by sliding and rotating 7c. The trochanter 7b rolls when the elevating mechanism 9 expands or contracts.

  The lower end of the frame 7 is in the frame lower part 10, and a plurality of adjustment holes 70 are formed in each. The height of the frame 7 can be adjusted by selecting the adjustment hole 70.

  Further, the upper limit and / or lower limit of the lifting rail 8 is set by the stopper fitting 71, the upper limit is set by the stopper fitting 71 provided on the upper side of the frame 7, and the lower limit is set by the stopper fitting 71 provided on the lower side. . The stopper fitting 71 is used in a timely manner and is not limited as long as it has a role of adjusting the height direction.

  A stopper member 80 is attached to the lower end of one end of the elevating rail 8 that contacts the shelf rail 3. Since this stopper member 80 comes into contact with the lower end of the shelf rail 3, the upper limit of the lifting rail 8 becomes the same height as the shelf rail 3, and the unloading operation of the needle rack 4 can be performed smoothly. It is considered that the movement to the elevating rail 8 can be efficiently performed without the needle rack 4 being caught.

  The structure of the lifting / lowering rail 8 forms a groove portion 8a for preventing the wheels (not shown) of the needle rack 4 from falling down and rolling, and to be securely mounted at a predetermined position. For example, the groove 8a is not limited as long as it has a shape that shows the lower side of an octagon, is U-shaped, and the wheel smoothly rolls on the groove 8a.

  In this structure, it is possible to contribute to features such as press molding that can be molded easily and at low cost, improved strength, and thinning of the steel material. And this structure is an example and it is also possible to form the groove part 8a with two strips (not shown).

In addition, by increasing the strength of the damper 90 and the link mechanism 91 of the lifting mechanism 9, the length of the lifting rail 8 can be extended, and a plurality of needle racks 4 can be taken out as well as a series. It is considered that workability is improved.

  Next, a series of flow of this unloading work will be described. First, the elevating rail 8 is set to A which is the same height as the shelf rail 3, and the adjustment in the height direction is performed. Then, using the caster 600 of the moving means 60 and the adjuster 610 of the fixing means 61, the leaf tobacco simple unloading device 5 is fixed in front of the opening of the leaf tobacco drying chamber 1. Thereafter, the needle rack 4 for suspending the leaf tobacco is moved to the lifting rail 8 and mounted on the lifting rail 8. Then, the elevating rail 8 is slowly lowered by the elevating mechanism 9 to the position B, which is a height at which the operator can easily take out the bag, due to the weight of the needle rack 4 and / or the leaf tobacco. Then, the operator unloads the needle rack 4 and moves to the picking table 20. The lightened lifting rail 8 is returned to the position A by the lifting mechanism 9. This flow will be repeated in the same manner.

  In another example, as shown in FIG. 4, the shelf rail 3 may be arranged at a position higher than two stages in the drying chamber 1, and in such a case, a two-stage or more link mechanism is provided. By using 91, it is possible to descend from the shelf rail 3 arranged at a higher position via the elevating rail 8. Therefore, the use of this leaf tobacco simple unloading device 5 facilitates the unloading operation. It is thought that it can be done.

The perspective view which shows an example of this invention 2 is an enlarged perspective view of the lifting mechanism. FIG. 3 is an enlarged perspective view of another example of the present invention. FIG. 4 is an enlarged perspective view of still another example of the present invention. FIG. 5 is a perspective view of a picking table showing an example of the present invention.
