Description

  The present invention relates to a cassette for loading a plurality of leaf-like crops, and more particularly to a cassette for loading a plurality of leaf-like crops that can be used in a supply device that supplies leaf-like crops one by one to a leaf-like crop sorting and packaging system or the like.

  There has been proposed an alignment supply mechanism that takes out leafy crops of non-uniform size, such as large leaves, one by one from the top of the bundle, arranges their posture, and supplies them to various automatic mechanisms in the subsequent stages (patented) Reference 1).

  In the leaf-like crop alignment supply mechanism described in Patent Document 1, an adsorption part in which a small-diameter circular inner adsorption port and an annular outer adsorption port surrounding the inner adsorption port are formed, and a suction mechanism that sucks air from the adsorption unit The large leaves can be sucked one by one from a cartridge containing a large number of large leaves by the suction mechanism, and the sucked large leaves can be transferred to a belt conveyor. For example, when there is a small large leaf on the top of the cartridge and a large large leaf on the bottom, the suction mechanism applies a negative pressure to the contact surface between the small large leaf on the top and the inner suction port. Adsorb and lift small large leaves. When the small large leaf is lifted and the small large leaf is separated from the large large leaf below the small large leaf, the suction mechanism also applies negative pressure to the contact surface between the lifted small large leaf and the outer suction port. Accordingly, the suction mechanism takes out the large leaves one by one from the cartridge without adsorbing the two large leaves.

  Also, a leaf-like crop sorting and packaging system has been proposed that can sort leaf-like crops such as large leaves based on their size, shape, etc., stack them into bundles, and package the bundled leaf-like crops ( For example, see Patent Document 2).

  The sorting and packaging system for foliage crops described in Patent Document 2 includes a transport cartridge for storing a plurality of foliate crops such as large leaves in a stack, and the transport cartridge is provided with 2 for preventing positional displacement and collapse of large leaves. Thin plate fins are fixed to the rotating plate. First, when the transport cartridge is in the range where the large leaves are stacked during transport on the cartridge supply conveyor, the rotation plate rotates to open the fins fixed to the rotation plate upward, Can be loaded into the transport cartridge. Next, when the transport cartridge is outside the range where the large leaves are stacked while being transported on the supply conveyor, the fins are closed and fixed, and the large leaves can be suppressed. In the transport cartridge described in Patent Document 2, when the removal of large leaves progresses and the number of stacked large leaves decreases, a space is formed between the fins and the large leaves, so that the large leaves cannot be suppressed by the fins. For this reason, the bottom plate of the transport cartridge is pushed up by the push-up member, and the large leaves are pressed against the fins to suppress the large leaves.

  However, leafy crops have large differences in size and are unstable in shape, and it has been difficult to take out leafy crops one by one from the top of the bundle according to conventional techniques.

  In the leaf-like crop alignment and supply mechanism described in Patent Document 1, the uppermost large leaves are lifted and separated one by one by the negative pressure from the inner suction port, but 2 due to moisture adhering to the surface of the large leaves. When the adsorbing force with the large leaves after the first sheet is strong, there is a problem that a plurality of large leaves are adsorbed at a time by the suction mechanism and transferred in a stacked state, or some large leaves fall during the transfer there were.

  In addition, in the leaf-type crop sorting and packaging system described in Patent Document 2, in order to load large leaves in the transport cartridge, fins fixed to a rotatable rotating plate are provided, and the push-up member moves the transport cartridge. The bottom plate was pushed up and the large leaves were suppressed by the fins, and the configuration of the transport cartridge was complicated. Further, since the conveyance cartridge having such a complicated structure is controlled, the control of the system becomes more and more complicated. Further, since the force for suppressing the large leaf is determined by the force for pushing up the push-up member, it is necessary to precisely control the force for pushing in order to make the force for suppressing the large leaf constant. In addition, since the number of large leaves that can be stacked on the transport cartridge is limited to several tens, there is a problem that a large number of transport cartridges must be prepared.

  The present invention has been made in view of the above-mentioned problems, and in a sorting and packaging system for taking out leafy crops one by one, the control and configuration on the system side can be simplified, and the simple configuration is low cost. It is an object to provide a foliage crop supply cassette that can be made and / or loaded with a large number of foliate crops.

  In order to solve the above-mentioned problems, a leaf-like crop loading cassette according to the present invention is a leaf-like crop loading cassette on which a plurality of leaf-like crops are loaded and the leaf-like crops are taken out one by one from the plurality of leaf-like crops. A base, and at least one guide provided on the base, and a restraining member that is movable in the vertical direction while being restricted from moving in the horizontal direction by the guide, and the restraining member includes: It is characterized by suppressing foliage crops loaded by its own weight.

  In the foliage crop loading cassette, the restraining member preferably has a shape that restrains at least two areas of the loaded foliage crops, and a leaf handle of the loaded foliage crops between the two areas. More preferably, a main vein extending from to the tip of the leaf is arranged. Further, it is preferable that the restraining member restrains the at least two regions by a pair of extending portions extending substantially parallel to the main vein.

  In the foliage crop loading cassette, it is preferable that a curved surface that reduces friction with the loaded foliage crop is formed on at least a part of the surface of the holding member.

  In the foliage crop loading cassette, it is preferable that the base has an opening through which light from a sensor for determining the presence or absence of the foliate crop can pass in a part of a region where the foliage crop is loaded.

  According to the present invention, the foliage crop loading cassette includes a holding member that is horizontally movable by the guide and is provided so as to be movable in the vertical direction, and suppresses the foliage crop loaded by the dead weight of the holding member. Therefore, when taking out a plurality of loaded leafy crops one by one from the top, it is possible to prevent a plurality of large leaves from being taken out at once by restraining by the weight of the restraining member. Since the restraining by the restraining member is due to the weight of the restraining member, the leafy crops can always be restrained with a constant force regardless of the number of leafy crops loaded, and the leafy crops are stably supplied one by one. can do. In addition, since the bundle of the plurality of leaf-like crops stacked is suppressed from above by the suppressing member, it can be made difficult to collapse even during the conveyance process and the extraction process. As described above, the leaf-like crop loading cassette according to the present invention can stably supply leaf-like crops one by one with a simple configuration of a restraining member whose movement in the horizontal direction is restricted by the guide. Furthermore, since it is not necessary to provide special control or mechanism on the system side, the control and configuration of the system can be simplified. Other effects will be described in the mode for carrying out the invention.

  Embodiments of the present invention will be described below with reference to the drawings. In addition, this invention is not limited to the following examples.

  The foliage crop loading cassette (hereinafter sometimes abbreviated as “cassette”) of the present invention is loaded with a plurality of foliage crops, and the plurality of foliage crops loaded are taken out one by one from the top. It is used when supplying leafy crops to a sorting and packaging system depending on the shape, size, surface scratches, etc. of the crops. A leaf-like crop is harvested or shipped in a state in which sheet-like leaves are separated one by one, such as blue shiso leaves (large leaves), sanchu, leaf tobacco, and autumn leaves. Hereinafter, after exemplifying a large leaf as a leaf-like crop and first explaining an example of a usage form of the leaf-like crop loading cassette, a structure of the leaf-like crop loading cassette will be described.

  FIG. 1 is an explanatory diagram showing an example of a usage pattern of a leaf-like crop loading cassette 1 of the present invention. In FIG. 1, the cassette 1 is used for a large leaf supply apparatus 20 that supplies large leaves one by one, sorts and packages large leaves.

  For example, as shown in FIG. 1, the large leaf supply device 20 includes a cassette supply / discharge device 30, a load pickup / conveyance device 50, and a control device (computer) (not shown). A plurality of large leaves (loads) are stacked and stacked on the foliage crop loading cassette 1. A plurality of large leaves are loaded on the foliage crop loading cassette 1 manually or automatically.

  The cassette supply / discharge device 30 includes a cassette transport means 31, a cassette stage 32, a cylinder 33 with brake, a cylinder 34, a cassette discharge means 35, various detection sensors 40 to 43, and the like. The cassette conveying means 31 conveys the cassette 1 to the cassette stage 32 and is realized by, for example, a conveyor or a roller, but is not limited to this. On the cassette stage 32, the cassette 1 conveyed by the cassette conveying means 31 is arranged.

  The brake-equipped cylinder 33 can move the cassette stage 32 up and down and adjust the large leaf in the cassette 1 to a position where it can be taken out by the load pickup / conveyance device 50. In addition, the cylinder 34 can lower the cassette stage 32 obliquely, discharge the empty cassette 1 to the cassette discharge means 35, and then lift the cassette stage 32 descended obliquely to the original position. The cassette discharging means 35 is for discharging the empty cassette 1 and is realized by, for example, a conveyor or a roller, but is not limited thereto.

  As the various detection sensors 40 to 43, a cassette detection sensor 40, a cassette entry detection sensor 41, a cassette upper surface detection sensor 42, a large leaf detection sensor 43, and the like are provided. The control device detects the position and presence of the cassette 1 or large leaf. Each configuration can be controlled. Each sensor can be composed of, for example, a light emitting element using an infrared LED and a light receiving element using a phototransistor, and detects an object when the light emitting element and the light receiving element are blocked by the object. You may set as follows. Alternatively, the object may be set to be detected when infrared light is applied to the object and light reflected from the object is received. The large leaf detection sensor 43 may be provided to face the light emitting element so that the light receiving element can receive light through the opening 7 of the leaf-like crop loading cassette 1. Each sensor is not limited to an optical sensor using infrared light, and may be constituted by other sensors.

  The cassette detection sensor 40 is an optical sensor that detects the cassette 1 based on the reflection from the cassette 1, and whether or not the next cassette 1 to be supplied to the cassette stage 32 exists at the front end of the cassette transport means 31. Is detected. Note that the cassette supply / discharge device 30 may include a stopper (not shown) at the tip of the cassette carrying means 31. The stopper may be, for example, a gate that opens and closes, or may be configured by a bar that moves up and down, and is not particularly limited. The stopper holds the next cassette 1 supplied to the cassette stage 32 at the front end of the cassette carrying means 31 while the cassette 1 is placed on the cassette stage 32. The cassette entry detection sensor 41 detects that the cassette 1 is placed on the cassette stage 32 based on the reflection from the cassette 1. More preferably, the cassette entry detection sensor 41 also detects that the cassette 1 is placed at a predetermined position of the cassette stage 32. The cassette upper surface detection sensor 42 detects that the cassette 1 has risen to a predetermined height based on the presence / absence of reflection from the large leaf loaded at the top of the cassette 1. Further, the cassette upper surface detection sensor 42 needs to raise the cassette stage 32 to the take-out position of the large leaf because the large leaf is taken out one by one and the height of the loaded large leaf is lowered, the reflection from the large leaf of the cassette 1 disappears. This is notified to a control device (not shown). As described above, the cassette stage 32 on which the cassette 1 is placed is raised to a predetermined height by the cylinder 33 with brake.

  The large leaf detection sensor 43 is an optical sensor for detecting the presence or absence of a large leaf in the cassette 1 based on the reflection from the large leaf and identifying that the cassette 1 is empty. The light from the large leaf detection sensor 43 is passed through the opening 7 of the leaf-like crop loading cassette 1 shown in FIG. 2 to be described later, and the presence or absence of large leaves in the cassette 1 is detected based on the presence or absence of the passing light or the presence or absence of the reflected light Can do. However, the presence or absence of large leaves in the cassette 1 may be detected by other methods, for example, without allowing the light from the sensor to pass through the opening 7 and using the intensity and color of the reflected light.

  1 includes an adsorber 51, a suction pump 52, a servo motor 53, a moving mechanism 54, a load carrying means 55, and the like. The large leaves loaded in the cassette 1 are sucked one by one by generating a negative pressure, and the sucked large leaves are lifted by the servo motor 53 and transferred to the load carrying means 55 by the moving mechanism 54 to cancel the generation of the negative pressure. Then, the large leaf is transported by the load transport means 55.

  The load carrying means 55 is for carrying a large leaf taken out from the cassette 1 and is realized by, for example, a conveyor or a roller, but is not limited thereto. In FIG. 1, the load carrying means 55 conveys large leaves in a direction extending perpendicular to the paper surface, so only the cross section is shown. In addition, the structure of the load pick-up / conveyance apparatus 50 is not limited to the structure of FIG. 1, For example, it is also possible to use the adsorption | suction part and suction mechanism described in patent document 1, and other It is also possible to adopt an extraction mechanism.

  The operation of the cassette supply / discharge device 30 in the large leaf supply device 20 will be described. First, the control device drives the cassette carrying means 31 to carry the leaf-like crop loading cassette 1 to the tip of the cassette carrying means 31 and slides it down to the cassette stage 32. Here, when the cassette 1 has already been supplied to the cassette stage 32, the cassette detection sensor 40 is used to operate a stopper (not shown) at the tip of the cassette conveying means 31 to stop the conveyance of the cassette 1. To do. Next, when the controller detects that the cassette 1 is supplied to the cassette stage 32 by the cassette entry detection sensor 41, the cassette stage 32 is moved to a predetermined position by the cylinder 33 with brake using the cassette upper surface detection sensor 42. Then, the picking-up / conveying device 50 starts taking out the large leaves. Here, when the control unit detects that the large leaf has been taken out by the load take-out conveying device 50 and the position of the large leaf in the cassette 1 has become low, the cassette upper surface detection sensor 42 causes the cylinder 33 with brake to move the cassette stage 32. Using the cassette upper surface detection sensor 42, the large leaf in the cassette 1 is adjusted to a position where it can be taken out by the load pickup / conveyance device 50. When the control device detects that the large leaf of the cassette 1 has become empty using the large leaf detection sensor 43, the control device returns the cassette stage 32 to the original position by the cylinder 33 with brake, and then drives the cylinder 34 to drive the cassette stage. 32 is lowered and the empty cassette 1 is discharged to the cassette discharging means 35. Thereafter, the cassette stage 32 is lifted again to the original position by the cylinder 34, and the next cassette can be supplied.

  2A, 2B, and 2C are a top view, a side view, and a front view, respectively, showing an example of the configuration of the leaf-like crop loading cassette 1 of the present invention. The foliage crop loading cassette 1 includes a base 2, a guide 3, and a holding member 4, and a plurality of large leaves 15 are loaded in a bundle. A foliate crop has a petiole that is connected to the stem and usually has a thin and wide leaf blade, and a main vein runs from the petiole to the tip of the leaf. In the following description, the main vein is regarded as a straight line and is called a “center line”. Although the leaf-shaped crop 15 has different shapes, the large-leaf supply device 20, the cassette supply / discharge device 30 and the leaf-shaped crop loading cassette 1 have a certain degree for each kind or size category (S, M, L, etc.). Since it is designed assuming a standardized standard product, the center line can also be identified from the standard product.

  The base 2 is a base on which a plurality of large leaves 15 are loaded, and at least one guide 3 is provided. As the base 2, for example, a rectangular flat plate larger than the size of the large leaf 15 to be loaded can be used. The shape is not limited to a quadrangle, but may be a triangle, a polygon, a circle, an ellipse, or a combination of these, or an inclination or a depression may be provided at the position of the loaded large leaf 15. Good.

  The base 2 may be provided with an opening 7. The opening 7 allows light from a sensor (for example, the large leaf detection sensor 43 in FIG. 1) that determines whether or not the large leaf 15 remains in the foliage crop loading cassette 1 to pass therethrough.

  The guide 3 restricts the movement of the restraining member 4 in the horizontal direction while being movable in the vertical direction. At least one guide 3 is provided in the vertical upward direction with respect to the base 2, and the restraining member 4 is provided in a predetermined direction. Allows falling within an area or with a predetermined trajectory. Although the movement of the restraining member 4 in the horizontal direction is restricted by the guide 3, it is not necessary to completely prohibit the movement, and it may be restricted within a predetermined region. Providing a plurality of guides 3 is preferable because the restraining member 4 can be prevented from tilting and can be stably dropped, and a uniform load can be applied to the large leaf 15.

  As the guide 3, for example, as shown in FIG. 2, a cylinder having a diameter passing through the guide hole 5 provided in the holding member 4 can be used. However, the guide 3 is not limited to a cylinder, and may be a quadrangular column, a T-type or H-type column, or a cone or a pyramid. Moreover, it may be a wall shape instead of a columnar shape, and the side wall of the cassette 1 or a positioning guide 10 to be described later may be used as the guide 3 as it is or after being processed. For example, (A), (B), and (C) of FIG. 3 are a top view, a side view, and a front view of another embodiment showing the relationship between the guide 3 and the holding member 4, respectively. 3, the inner peripheral surface of the side wall 3a on the right side (the petiole side) and the two cylinders 3b serve as the guide 3 to restrict the movement of the holding member 4 in the horizontal direction. A part of the petiole side wall 3 a and the two columns 3 b in FIG. 3 also function as the positioning guide 10. 5A, which will be described later, the wall-shaped guide 3 is inserted into the guide hole 5 of the restraining member 4. In FIG. 5C, a groove provided in the wall is used as the guide 3. The end portion of the restraining member 4 is disposed in the groove. The relationship between the guide 3 and the restraining member 4 is such that the restraining member 4 surrounds the guide 3 and restricts horizontal movement as shown in FIGS. 2 and 5A, and FIG. 3 and FIG. As described above, it is possible to adopt a mode in which the guide 3 surrounds the restraining member 4 to restrict the movement in the horizontal direction or a mode in which these are combined.

  In addition, the guide 3 is arranged with respect to the center line so that the horizontal restriction of the restraining member 4 is equal to the center line, in other words, the same force is applied to both sides of the center line of the large leaf. It is preferable that they are provided symmetrically. The guide 3 may be provided obliquely with respect to the base 2 in the vertical direction, or may be bent instead of a straight line. In the case of the guide 3 in which the restraining member 4 is movable in the vertical direction, since the force for restraining the large leaf can be set only by the weight of the guide 3, the restraining member 4 and the guide 3 can be easily designed. The guide 3 may be provided by being molded integrally with the base 2, or may be provided by being formed as a separate member and coupled to the base 2.

  Further, the base 2 is preferably provided with a positioning guide 10 for guiding the large leaf 15 so as to be easily loaded on the base 2. The positioning guide 10 can prevent the large leaf 15 from being misaligned. In FIG. 2, the positioning guide 10 has a wall shape, but may have a columnar shape, and the position thereof is not limited to the maximum width portion of the large leaf. Moreover, the function of the guide 3 which controls the horizontal movement of the restraining member 4 can also be given to the positioning guide 10, like a part of the petiole side wall 3a in FIG. 3 or the two cylinders 3b.

  The restraining member 4 is a member for restraining a plurality of large leaves 15 loaded by its own weight, and the trajectory or range of dropping is regulated by the guide 3. 4 (A) and 4 (B) are respectively a top view and a front view in which the holding member 4 of FIG. 2 is enlarged, and FIGS. 5 (A), 5 (B), 5 (C) and 4 (D) are respectively other views. It is the upper side figure and front view of the holding member 4 of this embodiment. The material of the restraining member 4 can be appropriately selected as long as it is hygienic without damaging the large leaf 15 and is, for example, plastic or acrylic resin. Further, the holding member 4 has a weight capable of applying an appropriate load to the large leaf 15. The holding member 4 may be made of several types with different weights corresponding to the size, shape, hardness, etc. of the leaf-like crop. Moreover, you may be comprised so that weight may be changed by making several thin boards into a set.

  It is preferable that the restraining member 4 has a shape that restrains two regions sandwiching a region where no load is applied between the loaded leafy crops. The large leaf 15 is applied with the load of the restraining member 4 in at least two regions by the restraining member 4, and a region where no load is applied by the restraining member 4 is formed between the two regions. By taking out the large leaves 15 in an area where no load is applied, the large leaves 15 can be taken out under a uniform load, and can be taken out one by one accurately. In addition, since the area | region where a load is not applied by the holding member 4 should just be provided between the two area | regions, two area | regions may be connected in one place or multiple places.

  Furthermore, it is preferable that a main vein extending from the petiole of the large leaf 15 loaded on the base 2 to the tip of the leaf is disposed between the two regions. The force concentrates on the two areas of the large leaf 15 by the removal operation. However, since the petioles and main veins of the large leaf 15 are hard, if these portions are included in the two regions, the large leaf 15 is broken or damaged by the extraction operation. There is a fear.

  Further, the holding member 4 includes a pair of extending portions 6 for holding the large leaves 15, and the pair of extending portions 6 can suppress two regions sandwiched between regions where no load is applied. preferable. The pair of extending portions 6 need not be linear, but preferably extend substantially parallel to the center line. Furthermore, it is preferable that a main vein extending from the petiole of the large leaf 15 to the tip of the leaf is disposed between the pair of extending portions 6. According to such a configuration, the pair of extending portions 6 are arranged so as to suppress a part of the left and right sides of the leaf centering on the main vein extending from the petiole of the large leaf 15 loaded on the base 2 to the tip of the leaf. Therefore, the removal operation can be realized under a uniform load, and the sheets can be accurately taken out one by one.

  Specifically, as shown in FIGS. 3 (A) and 4 (A), the holding member 4 is formed into a U-shape by a pair of extending portions 6 and a portion (connecting portion) connecting the extending portions. Although it is preferable to form a mold, it is not limited to such a shape. As shown in FIG. 5 (A), an annular (O-type) connected at both ends of a pair of extending portions 6 and Alternatively, as shown in FIG. 5 (C), it may be an H shape in which the middle portions of the pair of extending portions 6 are connected. Moreover, although it is suitable for a pair of extension part 6 to be formed in a rectangular flat plate, as shown to FIG 5 (D), you may be comprised by the stick | rod (circle or an elliptical column). In the restraining member 4 in FIG. 5C, the connecting portion may intersect the center line of the leaf-like crop, but as is clear from FIG. 5D, the pair of extending portions 6 are elliptic cylinders. Since the shape of the holding member 4 is mostly concentrated in the lower end region of the pair of extending portions 6, it is possible to avoid or reduce problems caused by the connecting portion intersecting the center line.

  Further, the holding member 4 may have a guide hole 5 into which the guide 3 shown in FIG. 2 is inserted. When the restraining member 4 is inserted into the guide 3 through the guide hole 5, the restraining member 4 applies a constant load to the large leaf 15 by its own weight and restrains the large leaf 15. The guide hole 5 may be elliptical, square, I-type, T-type, H-type, or the like depending on the cross-sectional shape of the guide 3. Moreover, the groove | channel which pinches | interposes the guide 3 may be sufficient. The guide hole 5 in FIG. 5A is a horizontally long I-type.

  Furthermore, when the extending portion 6 is formed of a rectangular flat plate, a curved surface that can reduce friction with the large leaf 15 may be formed on the surface or side surface of the extending portion 6 in contact with the large leaf. . Further, a rotating roller may be provided in the extending portion 6 to reduce friction with the large leaf 15.

  6A, 6B, and 6C are a top view, a first front view, and a second front view, respectively, showing another example of the configuration of the holding member of the leaf-like crop loading cassette of the present invention. is there. In FIG. 6B, a curved surface 8 is formed on the surface of the extending portion 6 on the side in contact with the large leaf 15. In FIG. 6C, a corrugated surface 9 is formed on the surface of the extending portion 6 on the side in contact with the large leaf 15. Further, the surface may be subjected to smooth fine processing. Thereby, the friction between the extending portion 6 and the large leaf 15 can be reduced. Furthermore, you may utilize a rod-shaped extension part like the extension part 6 of FIG.5 (C) and (D).

  As described above, according to the embodiment of the present invention, the leaf-like crops are prevented from being picked up by the restraining member by restraining the leaf-like crops loaded by its own weight, and the leaf-like crops are taken out one by one. For this reason, the supply system side does not require the control and structure for preventing the two crops of leafy crops from being taken. Therefore, the control and structure on the supply system side can be simplified. In addition, since the structure of the leaf-shaped crop loading cassette is simple, the cost of creating the leaf-shaped crop loading cassette can be reduced.
