Description

  The present invention relates to a sorting apparatus that sorts a sorting target object such as a book, a package of various components, or a sealed body into a plurality of types based on sorting information.

  2. Description of the Related Art As a sorting apparatus that automatically sorts sorting targets into a plurality of target types and correctly stacks the stacked objects in a stacking box, an apparatus that targets a sealed letter or the like is known (for example, see Patent Document 1).

  This type of conventional sorting apparatus is configured such that sorting objects sequentially supplied from a supply device are individually accommodated in a large number of carrier boxes moving on a closed loop, and a plurality of stacking boxes are provided below the moving paths of the carrier boxes. They are arranged in stages, objects to be sorted are dropped from the carrier box, and are sorted in the corresponding stacking boxes. That is, when the carrier box moves to the corresponding sorting position, the bottom portion is opened to drop the sorting object, and is stacked in the corresponding stacking box located below.

  In this case, with respect to the lower stacking box, the chute provided on the side of the upper stacking box receives the sorting object dropped from the carrier box and guides it to the lower stacking box. It is composed.

  Usually, an inclined guide portion for guiding a sorting object toward an accumulation box located diagonally below is provided at a lower end portion of the chute. Further, since the chute has a drop corresponding to the height of the storage box located at the upper stage, the sorting target object dropped from the carrier box is accelerated by this drop difference.

  For this reason, if the weight of the sorted object is heavy and the inertia is large, the object to be sorted may jump over the upper opening of the storage box without being decelerated at the inclined guide portion, and is securely stored in the corresponding storage box. It was difficult to make it.

On the other hand, when the sorting object is light in weight and a gum tape or the like is stuck on the outer surface, the sorting object stops on the inclined guide portion due to frictional resistance between the sorting object and the inclined guide portion. As a result, the subsequent sorting operation may not be performed smoothly.
JP-A-11-79372

  As described above, when the sorting object is put into the lower stacking box by using the chute, the state of the sorting object into the stacking box changes depending on the weight of the sorting object, the exterior state, and the like. It was difficult to reliably accumulate in a box.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a sorting apparatus capable of reliably stacking sorting objects in a corresponding stacking box using a chute.

    A sorting device according to the present invention sequentially supplies a sorting object having sorting information in a certain direction, a feeding device that reads the sorting information, and a sorting object that is respectively transferred in a certain direction and sequentially supplied by the feeding device. Are individually accommodated, and when moved to a predetermined sorting position based on the sorting information, the bottom part is opened, and a plurality of carrier boxes for dropping the sorting objects and the corresponding sorting positions below the transfer path of the carrier box are arranged. An upper stacking box, and a lower stacking box having a chute disposed at a lower stage of the upper stacking box and having a receiving port arranged at a corresponding sorting position, wherein the chute is located at a side of the upper stacking box. The lower end is provided with a guide portion which is inclined at the lower end toward the upper surface opening of the lower stacking box. A sliding surface for contact with the object, characterized in that a low friction arrangement.

  As a configuration for reducing the frictional resistance of the sliding surface, it is preferable to provide a plurality of linear projections having a corrugated cross section formed along the moving direction of the sorting object.

  In the present invention, the inclined guide portion provided at the lower end of the chute includes a pair of rollers in a direction perpendicular to the guide direction, and an endless sheet material bridged between the pair of rollers. The sorting object may be moved toward the upper surface opening of the stacking box by the rotational movement of the sheet material accompanying the rotation of the roller.

  In this case, at least one of the pair of rollers may be configured to be rotationally driven by a motor.

  Further, in the present invention, the upper side of the inclined guide portion is rotatably supported by the chute main body, and the lower side is movably supported by a spring body, and rotates downward by the weight of the sorting object. May be configured.

  Further, in the present invention, a deceleration unit may be provided inside the chute to reduce the falling speed of the sorting object dropped from the carrier box.

  A movable plate whose upper side is pivotally supported on the opposite guide surface side inside the chute so as to be rotatable, and whose deceleration surface is supported by an elastic material so as to maintain an inclination angle toward the guide surface side inside the chute. Should be used.

  A brush member made of an elastic material may be provided on the lower side of the movable plate.

  Further, a belt-shaped speed reduction member whose upper end is attached to the guide surface side inside the chute and whose middle portion in the longitudinal direction bulges toward the guide surface side inside the chute may be used as the speed reduction means.

  According to these inventions, when a sorting object is thrown into a stacking box arranged at the lower stage through a chute and is stacked, a sliding surface of the inclined guide portion provided at the lower end of the chute comes into contact with the sorting object. Is configured to have a low frictional resistance, so that even a sorting object that is lightweight and has a relatively large outer surface contact resistance can be reliably accumulated in the corresponding accumulation box without stagnation in this portion.

  In addition, when the inclined guide portion is rotatable downward by the weight of the sorting object, the falling speed of the heavy sorting object can be buffered by the above-described rotation operation, and the sorting object can be buffered. Can be reliably accumulated in the corresponding accumulation box.

  Furthermore, if the speed reducing means for reducing the falling speed of the sorting object thrown from the carrier box is provided inside the chute, the falling speed of the sorting object can be adjusted to a speed suitable for throwing into the stacking box. In addition, the sorting objects can be reliably accumulated in the corresponding accumulation box.

  According to the present invention, when the sorting object is guided into the stacking box using the chute, the sorting object does not jump over the stacking box or stagnate on the chute side, as in the related art, without fail. It can be guided and accumulated in the accumulation box.

  Hereinafter, an embodiment of a sorting device according to the present invention will be described with reference to the drawings.

  Here, FIG. 1 is a schematic diagram showing the entire sorting apparatus, FIG. 2 is a front view showing the relationship between the chute, the carrier box and the collecting box, which are main parts of the present invention, and FIG. 3 is a perspective view showing the configuration of the chute. 4, FIG. 4 is an enlarged view showing a speed reducing means provided in the chute, FIG. 5 is an enlarged view showing a configuration in which an inclined guide portion at the lower end of the chute is rotatable, and FIG. 6 is a front view of a chute provided with another speed reducing means. FIG.

  In FIG. 1, a sorting device 11 sorts a sorting target such as a book or a package of various parts, a sealed body, or the like into a plurality of types. A large number of carrier boxes 14 for individually accommodating the objects 12, a transport mechanism 15 for transporting the carrier boxes 14 in a certain direction, a stacking box 16 installed in a plurality of stages below a transfer path of the carrier box 14, and a lower stacking box 16 Has chutes 17 and 18 for guiding the sorting object.

  The supply device 13 has a suction belt 21 for conveyance and a reading device 22. The sorting object 12 has sorting information such as a barcode attached thereto, and the sorting objects 12 are arranged such that the sticking surface of the sorting information faces in a certain direction. The suction belt 21 individually suction-conveys the sorted sorting objects 12, and sequentially supplies the sorting objects 12 to the carrier box 14. The reading device 22 reads the sorting information of the sorting target 12 held on the suction belt 21 and supplied to the carrier box 14. This sorting information is input to a control device (not shown). The control device stores which carrier box 14 the sorting object 12 is supplied to in a corresponding relationship.

  The carrier boxes 14 are attached at equal intervals to the outer periphery of an endless chain 24 constituting the transport mechanism 15. The transport mechanism 15 includes a pair of toothed wheels 25 and 26 that are driven to rotate by a drive motor (not shown), and the endless chain 24 that extends over the toothed wheels 25 and 26. Are transported in a certain direction.

  The carrier box 14 has a box shape with an open front surface (a surface facing outward in the figure) and an upper surface. The carrier boxes 14 individually store the sorting objects 12 sequentially supplied from the supply device 13 and transfer the objects in a certain direction. As shown in FIG. 2, the carrier box 14 is attached so as to be inclined in the traveling direction. In addition, the bottom plate is configured to be openable, and the release plates 27a, 27b, and 27c provided at predetermined sorting positions open the bottom plate engaged with them and drop the sorting object 12. Let it.

  As described above, the stacking boxes 16 are provided in a plurality of stages below the transfer path of the carrier box 14, and the uppermost stacking box is 16a, and the lower stacking boxes are 16b and 16c. Of the stacking boxes 16a, 16b, 16c, the uppermost stacking box 16a is disposed immediately below a predetermined sorting position where the corresponding release mechanism 27a is provided, and sorts the sorting target 12 dropped from the carrier box 14. Store and accumulate directly. The other stacking boxes 16b and 16c are provided in a plurality of stages below the uppermost stacking box 16a, and store and stack the sorting objects 12 dropped from the carrier box 14 via the chutes 17 and 18. .

  The chute 17 is for the stacking box 16b located at the middle stage, and the chute 18 is for the stacking box 16c located at the lowermost stage, and their upper end receiving ports are provided with corresponding release mechanisms 27b, 27c. It is arranged at the sorting position.

  As shown in FIGS. 2 and 3, these chutes 17 and 18 are composed of chute main bodies 30 and 31 installed in the vertical direction on the sides of the collecting boxes 16a and 16b, and inclined guide portions 32 provided at the lower ends thereof. , 33 and side plates 35 that cover both sides of both chute bodies 30, 31.

  Each of the inclined guide portions 32 and 33 guides the sorting object 12 that has fallen in the chutes 17 and 18 toward the upper surface openings of the corresponding collecting boxes 16b and 16c, and is inclined downward. Further, the upper surfaces of the inclined guide portions 32, 33, that is, the sliding surfaces 32a, 33a that come into contact with the sorting object 12, are frictional due to the frictional resistance of the inner surfaces of the shot bodies 30, 31 that come into contact with the sorting object 12. A configuration with low resistance is used. As a configuration having a small frictional resistance, for example, as shown in FIG. 3, a plurality of projections 34 having a cross section having a waveform and being linearly formed along the moving direction of the sorting object 12 are used. .

  Here, the inclination guide portion 32 of the middle chute 17 is fixed at a predetermined inclination angle. On the other hand, the inclined guide portion 33 of the lowermost chute 18 has its upper side 33b rotatably supported by the lower end of the chute main body 31, as shown in FIG. The lower side 33c is movably supported by a spring body 36 stretched between the side plate 35 and the lower side 33c. The lower side 33c is rotatable downward by the weight of the sorting object 12 falling in the chute 18. I have.

  The chute main body 30 of the middle chute 17 is formed almost entirely vertically, but the chute main body 31 of the lowermost chute 18 has an upper half that is vertical, but the lower half has a corresponding stacking box 16c. It is slightly inclined toward. The left surfaces of the chute bodies 30 and 31 in the figure serve as guide surfaces 30a and 31a for the sorting object 12 dropped from the carrier box 14.

  A movable plate 37 is provided inside the middle chute 17 as a speed reducing means for reducing the falling speed of the sorting object 12 loaded from the carrier box 14. A support member 40 is provided on the upper side of the chute 17 opposite to the guide surface 30a and opposite to the guide surface 30a, and the upper side 37a of the movable plate 37 is located on the support member 40 side as shown in FIG. It is pivotably supported.

  The movable plate 37 is inclined downward so that its surface (deceleration surface) faces the guide surface 30a side of the chute 17, and is movably supported by an elastic member 38 such as a spring while maintaining the inclination angle. Is done. Further, a brush member 39 made of an elastic material is provided on a lower side 37b of the movable plate 37.

  In the above configuration, the sorting objects 12 are sequentially supplied by the supply device 13 and individually stored in the respective carrier boxes 14 which are transported in a certain direction by the transport mechanism 15. At this time, the sorting device 12 has read the sorting information attached to the sorting object 12. When the carrier box 14 accommodating each sorting object 12 reaches the corresponding predetermined sorting position based on the read sorting information, the control device (not shown) controls the release mechanisms 27a, 27b, 27c provided at the sorting position. Make one work. For this reason, the bottom plate of the corresponding carrier box 14 is opened by the operated release mechanism, and the accommodated sorting object 12 falls.

  For example, in FIG. 2, when the release mechanism 27a operates, the bottom plate of the carrier box 14 that has passed over the release mechanism 27a opens immediately after passing. For this reason, the sorting object 12 housed inside slides out from the inclined carrier box 14 diagonally to the lower left in the figure, and its lower end falls to the left side in the corresponding accumulation box 16a. Therefore, it is finally stored horizontally in the stacking box 16a and stacked.

  Further, when the release mechanism 27b operates, the bottom plate of the carrier box 14 that has passed over the release mechanism 27b opens immediately after passing, so that the sorting target 12 housed inside is separated from the inclined carrier box 14. It slides diagonally to the lower left in the figure and enters the middle chute 17 from the upper end receiving port.

  In this case, the sorting object 12 comes into contact with the movable plate 37 and the brush member 39 serving as the deceleration means and descends while sliding on them, so that the descending speed is not so high. As described above, the sorting object 12 that has reached the inclined guide portion 32 at an appropriate speed is horizontally stored in the corresponding accumulation box 16b while being slid on the inclined guide portion 32, and is accumulated.

  At this time, the sorting object 12 is decelerated to an appropriate speed by the movable plate 37 or the like, but the sliding surface 32a of the inclined guide portion 32 is provided with a linear projection 34 to reduce frictional resistance. Therefore, while maintaining this speed, the sheet is reliably moved into the collecting box 16b. That is, even if the sorting object 12 is a light weight, and even if it is an exterior with a relatively large frictional resistance wrapped with a gum tape or the like, the frictional resistance of the sliding surface of the inclined guide portion 32 is reduced. 12 does not stay here, and reliably moves into the accumulation box 16b.

  Further, a brush member 39 is provided on the lower side 37b of the movable plate 37 as a deceleration means, in order to prevent the sorting object 12 from being clogged. In other words, when the movable plate 37 is formed as a rigid body up to the brush member 39, if the outer shape of the sorting object 12 is somewhat thick and light, for example, if the electronic component is wrapped with styrofoam or the like, the movable plate 37 Since the supporting elastic member 38 does not bend much, the sorting object 12 may be sandwiched between the lower side of the movable plate 37 and the guide surface 30a.

  Therefore, if the length of the rigid portion of the movable plate 37 is shortened and a brush member 39 made of an elastic material is provided on the lower side portion 37b, the brush can be formed even if the elastic material 38 supporting the movable plate 37 does not bend so much. Since the member 39 is bent, the sorting object 12 is not sandwiched between the member 39 and the guide surface 30a, and the sorting can be performed reliably and smoothly.

  If the sorting object 12 is sufficiently heavy, the movable plate 37 may have a rigid body up to a portion corresponding to the brush member 39 without providing the brush member 39.

  Next, a case where the release mechanism 27c operates will be described. When the release mechanism 27c operates, the bottom plate of the carrier box 14 that has passed over the release mechanism 27c opens immediately after passing. For this reason, the sorting object 12 housed inside slides from the inclined carrier box 14 to the lower left in the figure, and enters the lowermost chute 18 from its upper end receiving port.

  In the example shown in the figure, since the speed reducing means is not provided at the entrance of the chute 18, the sorting object 12 falls as it is without being decelerated. However, since the lower half of the chute main body 31 is inclined, the guide is provided. The surface is slightly decelerated by contacting the surface 31a. At the same time, the guide surface 31a prepares a correct posture, and falls on the inclined guide portion 33 with the correct posture.

  The upper side 33b of the inclined guide portion 33 is rotatably supported by the lower end of the chute main body 31 and the lower side portion 33c side is movably supported by the spring body 36, so that it falls in the chute 18. The object 12 is rotated downward by the weight of the sorting object 12 and cushioned. Due to the buffering operation of the inclined guide section 33, the sorting target object 12 is decelerated and put into the corresponding stacking box 16c. Further, the downward rotation of the inclined guide portion 33 increases the throw angle from the inclined guide portion 33 into the stacking box 16c, so that even if the sorting object 12 is thrown in at a considerable speed, the conventional manner is achieved. There is no possibility of jumping over the opening of the collecting box, and it is surely put into the corresponding collecting box 16c.

  Next, another configuration example of the inclined guide portion provided at the lower end of the chute 17 for the middle stage and the chute 18 for the lowermost stage will be described with reference to FIGS. 7 and 8. Parts corresponding to those shown in FIGS. 2 and 3 are denoted by the same reference numerals.

  In FIG. 7, also in this embodiment, the collecting boxes 16 are provided in a plurality of stages below the transfer path of the carrier box 14, and the uppermost collecting box is 16a, and the lower collecting boxes are 16b and 16c. And Of the stacking boxes 16a, 16b, 16c, the uppermost stacking box 16a is disposed immediately below a predetermined sorting position where the corresponding release mechanism 27a is provided, and sorts the sorting target 12 dropped from the carrier box 14. It is accommodated and stacked via a vertical guide plate 51. The lower end of the guide plate 51 is bent obliquely downward toward the stacking box 16a.

  The other stacking boxes 16b and 16c are provided in a plurality of stages below the uppermost stacking box 16a, and store and stack the sorting objects 12 dropped from the carrier box 14 via the chutes 17 and 18. . The upper end receiving ports of the chute 17 for the middle stacking box 16b and the chute 18 for the lowermost stacking box 16c are arranged at predetermined sorting positions where the corresponding release mechanisms 27b and 27c are provided.

  As shown in FIGS. 7 and 8, these chutes 17 and 18 are composed of chute main bodies 30 and 31 installed vertically on the sides of the collecting boxes 16a and 16b, and inclined guide portions 52 provided at the lower ends thereof. , 53 and side plates 35 that cover both sides of both chute bodies 30, 31.

  The chute body 30 of the middle chute 17 is formed almost entirely vertically, while the chute body 31 of the bottom chute 18 has an upper half that is vertical but a lower half that faces the corresponding collecting box 16c. It is slightly inclined. The left surfaces of the chute bodies 30 and 31 in the figure serve as guide surfaces 30a and 31a for the sorting object 12 dropped from the carrier box 14.

  Further, inside the middle chute 17, a deceleration means similar to that shown in FIG. 2, that is, a movable plate 37 is provided to reduce the falling speed of the sorting object 12 inserted from the carrier box 14. I have.

  Each of the inclined guide portions 52 and 53 guides the sorting object 12 that has fallen in the chutes 17 and 18 toward the upper surface openings of the corresponding collecting boxes 16b and 16c, and is inclined downward. These inclined guide portions 52, 53 are formed by a pair of rollers 52a, 52b and 53a, 53b in a direction orthogonal to the guide direction, and endless sheet materials 52c and 53c bridged between the pair of rollers. It is configured. At least one of the pair of rollers 52a and 53a is driven to rotate by motors 54 and 55.

  These inclined guides 52 and 53 cause the sorting object 12 that has fallen by the rotational movement of the sheet materials 52c and 53c accompanying the rotation of the rollers 52a and 52b and 52a and 53b to be placed in the upper opening of the corresponding accumulation box 16b or 16c. Move toward

  Here, the inclination guide portion 52 of the middle chute 17 is fixed at a predetermined inclination angle. On the other hand, the inclined guide portion 53 of the lowermost chute 18 has its upper side 53 b side pivotally supported by the lower end of the chute main body 31 as shown in the figure. The lower side 53c is movably supported by a spring body 36 stretched between the side plate 35 and the lower side 53c. The lower side 53c is rotatable downward by the weight of the sorting object 12 falling in the chute 18. I have.

  In the above configuration, when the carrier box 14 accommodating each sorting object 12 reaches the corresponding predetermined sorting position, one of the release mechanisms 27a, 27b, 27c provided at the sorting position operates. Therefore, the corresponding bottom plate of the carrier box 14 is opened, and the accommodated sorting object 12 falls.

  For example, when the release mechanism 27a operates, the bottom plate of the carrier box 14 that has passed over the release mechanism 27a opens immediately after passing. For this reason, the sorting objects 12 housed inside slide out from the carrier box 14 to the lower left in the figure, fall into the stacking box 16a, are housed horizontally, and are stacked.

  Also, when the release mechanism 27b operates, the bottom plate of the carrier box 14 that has passed above opens immediately after passing, so that the sorting object 12 housed inside slides out diagonally to the lower left in the figure, and Entry chute 17 from the upper end receiving port.

  In this case, the sorting object 12 comes into contact with the movable plate 37 and the brush member 39, which are deceleration means, and descends at an appropriate speed while sliding on these. The sorting object 12 that has reached the inclined guide portion 52 in this way is surely transferred into the corresponding stacking box 16b by the movement of the endless sheet material 52c accompanying the rotation of the pair of rollers 52a, 52b, and is horizontally moved. It is housed in a state and accumulated.

  At this time, even if the sorting object 12 is lightweight and has a relatively large frictional resistance around which a gum tape or the like is wrapped, the sorting object 12 is forced to be transferred by the inclined guide portion 52. , And reliably move into the collecting box 16b.

  When the release mechanism 27c operates, the bottom plate of the carrier box 14 that has passed over the release mechanism 27c opens immediately after passing, and the sorting object 12 housed inside slides out diagonally to the lower left in the figure, The vehicle enters the lowermost chute 18.

  The sorting object 12 that has fallen in the chute 18 is slightly decelerated by the inclined lower half of the chute main body 31, is simultaneously adjusted to a correct posture, and falls on the inclined guide 53.

  The upper side 53b of the inclined guide 53 is rotatably supported by the lower end of the chute main body 31 and the lower side 53c is movably supported by the spring body 36, so that the inclined guide 53 falls in the chute 18. The object 12 is rotated downward by the weight of the sorting object 12 and cushioned. The sorting object 12 that has reached the inclined guide portion 53 in this way is reliably transferred into the corresponding accumulation box 16c by the rotational movement of the endless sheet material 53c accompanying the rotation of the pair of rollers 53a, 53b. They are stored in a horizontal state and stacked.

  Also in this case, the sorting guide 12 is forcibly transporting the sorting target 12, so that even if the sorting target 12 is a light-weight and has a relatively large frictional resistance, there is no delay here. It surely moves into the accumulation box 16c.

  In the inclined guide portions 52 and 53, the endless sheet members 52c and 53c are forcibly moved by the motors 54 and 55. It may be supported in a free (rotatable) state by a pair of rollers 52a, 52b and 53a, 53b. For example, when the sorting object 12 has a certain weight, considerable inertia is generated when falling in the chutes 17 and 18, and the inertia causes the free sheet materials 52c and 53c to rotate and move. The sorting objects can be stored in the corresponding stacking boxes 16b and 16c as they are.

  In each of the above embodiments, the inclination angles of the inclined guide portions 32 and 52 of the middle chute 17 are fixed, but depending on the shape and weight of the sorting object, the lowermost chute 17 shown in FIG. The same configuration as the inclined guide plate 33 may be configured to be able to rotate downward.

  Although no lowering means is provided in the lowermost chute 18, a lowering means such as the movable plate 37 or the brush 39 shown in FIG. Is also good. In addition, a belt-shaped speed reduction member 41 may be provided as the speed reduction means as shown in FIG. The belt-shaped reduction member 41 has an upper end attached to a guide surface side opposite to the guide surface 31a inside the chute 18 and a middle portion in the longitudinal direction bulging and curving toward the guide surface 31a side. .

  With this configuration, the sorting object 12 that falls in the chute 18 is joined to the guide surface 31a at the bulging curved portion of the belt-shaped reduction member 41, so that the sorting object 12 can be decelerated effectively. . Of course, the belt-shaped reduction member 41 may be provided in the middle chute 17.
