Description

  The present invention relates to a vibrating conveyor device that moves an object to be transported (hereinafter referred to as a transported object) while applying vibration.

  The vibration conveyor device is a facility device for transporting (transferring) a transported object in a desired direction while vibrating. For example, the vibrating conveyor device can convey the object to be conveyed in a lump shape while conveying the object while giving a space to a plurality of objects to be conveyed that are in the assembled state. Therefore, the vibration conveyor device is widely used in various fields. There are various types of such vibration conveyor devices, and a trough and a counterweight (also referred to as a balance weight) that serve as a conveyance path for conveying an object to be conveyed are vertically opposed to each other. A structure is known that is connected and vibrated by hinge arms (movable levers) that are rotatable with respect to each other.

  For example, Patent Document 1 discloses a vibrating conveyor device that has the same basic structure as described above and is improved. The vibratory conveyor device of Patent Document 1 utilizes a counterweight as a second trough so that an object to be conveyed can be conveyed in the opposite direction between the original trough (first trough) and the counterweight (second trough). It is configured. This vibrating conveyor device conveys the object to be conveyed in a certain direction by the first trough, drops it to the second trough side through the transfer path provided at the end, and further moves the object to be conveyed by the second trough in the opposite direction. Transport.

  Since the vibrating conveyor device uses the counterweight as the second trough and conveys the object to be conveyed, the facility can be effectively used. In addition, since this vibrating conveyor device can transport the object to be transported in the reverse direction, it can be transported at a manufacturing plant or the like that performs predetermined processing (heating, cooling, sterilization, etc.) on the object to be transported during transport. You can shorten the road. Therefore, this vibration conveyor device has an advantage that the occupied area can be reduced.

  Prior to this, in Patent Document 1, the counterweight is used as the second trough so that the object to be conveyed is conveyed in the same direction by the original trough (first trough) and the second trough. It is also disclosed that there was a vibratory conveyor device constructed. This type of vibration conveyor device has an advantage that the area occupied can be reduced because the conveyance capacity is doubled when it is desired to convey the object to be conveyed in the same direction.

2001-192110

  The vibration conveyor apparatus disclosed in Patent Document 1 discloses a case where an object to be conveyed is conveyed from one end of a trough to the other end. However, in a manufacturing factory or the like, there is a case where it is desired to supply an object to be conveyed being conveyed by a vibration conveyor device to a plurality of locations during the conveyance. The vibrating conveyor device disclosed in Patent Document 1 does not consider such points. Therefore, in order to cope with such a request, it is necessary to deal with such a situation by arranging a plurality of short vibrating conveyor devices. This complicates the equipment and increases the cost.

  Accordingly, an object of the present invention is to solve the above-described conventional problems, and to provide a vibrating conveyor device that can supply an object to be conveyed to a midway position of a trough as necessary.

  The object includes a trough and a counterweight for transporting the object to be transported. The trough is disposed on the upper side and the counterweight is disposed on the lower side, and the transported object can be transported using the counterweight as a second trough. The vibration conveyor apparatus formed as described above can be achieved by a vibration conveyor apparatus characterized in that an opening is provided in the middle of the trough to drop the object to be conveyed toward the counterweight.

  According to the present invention, even if the trough is set to be long, it is possible to transport the article TA to be supplied by providing an opening at an arbitrary position. And if the magnitude | size of the opening to set is adjusted suitably, a part of to-be-conveyed object will be dropped by an opening, and another part can be conveyed downstream. Therefore, since a to-be-conveyed object can be supplied to several places with one vibration conveyor apparatus, it can convey efficiently and can simplify an installation.

  It is more preferable that a shutter for opening and closing the opening is further provided. By providing the shutter in this way, it is possible to easily switch the supply and stop of the conveyed object at the position where the opening is provided. Therefore, the object to be transported can be transported more efficiently.

  In addition, a chute that guides the object to be dropped from the opening to the counterweight side is provided so as not to interfere with the surrounding structure. It is good also as a structure provided with the expansion | deployment receiving part which drops further, developing a to-be-conveyed object. In this case, since the development receiving portion is provided on the counterweight side below the opening, it is only necessary to arrange the chute so as not to interfere with the surrounding structure. Therefore, the transported object can be dropped while being developed with a compact structure that can avoid interference with the peripheral part.

  Moreover, you may employ | adopt the structure where the net | network for sieving a to-be-conveyed object is further installed in at least one of the said trough and the said counterweight. In this case, when the transported object includes large and small objects, further sorting can be performed.

  Moreover, you may employ | adopt the structure where the said opening is provided near to one side in the width direction of the said trough. In this case, a part of the conveyed object can be dropped as necessary. Moreover, you may employ | adopt the structure further provided with the conveyance stop means which dams the said to-be-conveyed object in the upstream of the said opening. In this case, the objects to be conveyed flowing downstream can be limited as necessary.

  Furthermore, a structure in which a plurality of openings are formed in the trough may be employed. If it does in this way, a to-be-conveyed object can be supplied now to arbitrary several places.

  As described above, according to the present invention, it is possible to provide an oscillating conveyor device that can supply a transported object to an intermediate position of a trough as necessary.

  Hereinafter, a vibrating conveyor apparatus according to an embodiment of the present invention will be described with reference to the drawings. Here, the vibration conveyor apparatus in the case of conveying the cigarette TA as an example of a to-be-conveyed object is demonstrated.

  FIG. 1 is a perspective view illustrating an appearance of a vibrating conveyor device 1A according to the first embodiment. This vibrating conveyor apparatus 1A is arranged so that the trough 10 is on the upper side and the counterweight 20 is on the lower side so as to face each other (facing each other). The vibration conveyor device 1A includes a base frame 2 serving as a basic skeleton, and the trough 10, the counterweight 20 and other components are assembled to the base frame 2.

  The trough 10 is formed in a long saucer shape with an open upper surface. The trough 10 has a concave cross-sectional shape when viewed in the transport direction (from the upper right to the lower left in FIG. 1) CD. Under this, a counterweight 20 is arranged to face. Originally, the counterweight is a member provided to counteract the impact when the trough vibrates. The counterweight 20 of this embodiment is also set to a weight substantially equal to that of the trough 10, and fulfills the function of canceling the impact. The main body portion 21 of the counterweight 20 is a belt-like weight disposed below the trough 10, and is disposed in a rectangular shape. The interior of this rectangle is a space. Therefore, if a bottom plate for receiving an object to be conveyed is provided in this space, it can function as a second trough.

  If a bottom plate is provided on the entire surface of the counterweight 20, the chopped tobacco TA can be conveyed in the same manner as the trough 10. This form is the same as the conventional structure disclosed in Patent Document 1 described above. However, as will be described later, the trough 10 of this embodiment is provided with an opening. And it forms so that the cut tobacco TA which has fallen may be received with the counterweight 20. FIG. This vibration conveyor apparatus 1A has a bottom plate 22 formed only at a predetermined position. The structure of this point will be described in detail later.

  FIG. 2 is an enlarged view of a part of the vibrating conveyor device 1A. The basic structure of the vibration conveyor device 1A will be described with reference to FIG. The trough 10 located on the upper side and the counterweight 20 are connected by a plurality of hinge arms 3. An intermediate portion of the hinge arm 3 is rotatably supported by a bearing 4. The plurality of bearings 4 are fixed to the support member 5. The support member 5 is supported via a plurality of vibration isolation springs 6 set on the base frame 2. An excitation spring 7 is provided between each hinge arm 3 and the fixed side.

  Next, the drive system will be described. In FIG. 2, a part of the drive part is taken out toward the front so that the structure can be easily confirmed. A motor 50 as a drive source is installed on the base frame 2. The rotation of the motor 50 is transmitted to the eccentric shaft 52 by a V belt 54 stretched between a pulley 51 of the motor and a pulley 53 fixed to the eccentric shaft 52. The base portion of the vibration rod 55 is attached to the eccentric shaft 52, and the tip portion of the vibration rod 55 is sandwiched between two rubber plate springs 56 fixed to the side surface of the trough 10.

  With the above configuration, when the motor 50 is driven, the rotation is converted into a reciprocating motion by the vibration rod 55 via the eccentric shaft 52. Therefore, since the upper trough 10 can be vibrated in the conveyance direction CD, the cut tobacco TA in the trough 10 can be conveyed while being vibrated. Since the counterweight 20 disposed below the trough 10 is also vibrated via the hinge arm 3 and the vibration spring 7, the chopped tobacco TA can be similarly conveyed.

  About the structure demonstrated above, it is substantially the same as the conventional vibration conveyor apparatus. Hereinafter, the characteristic configuration of the vibration conveyor device 1A of the first embodiment will be further described with reference to FIG. 1 again.

  An opening 11 is provided on the bottom surface of the trough 10. The opening 11 can be opened and closed by a shutter 12 driven by an actuator 13. Therefore, if necessary, the cigarette TA can be dropped by opening the shutter 12. On the other hand, when the shutter 12 is closed, the cut tobacco TA can be continuously conveyed downstream. Although FIG. 1 shows the case where one trough 10 is provided in the trough 10, two or more apertures 11 may be provided as necessary.

  A chute 15 is provided from the bottom of the opening 11 toward the counterweight 20 serving as the second trough. In the case of an object to be transported that is small and relatively light in weight, such as the cut tobacco TA, the chute 15 is provided in this manner, so that it can be prevented from jumping out and scattering. Since the trough 10 and the counterweight 20 vibrate in opposite phases, it is desirable that the chute 15 is formed of a material having flexibility and moderate durability in a cylindrical shape. For example, the chute 15 can be formed of canvas or the like.

  Further, if the tobacco TA is dropped vertically from the opening 11, it may be agglomerated at the dropping position, which is not preferable. Therefore, it is desirable that the shutter 12 is opened obliquely and the tobacco TA is dropped gradually. Therefore, as shown in FIG. 1, the position of the chute 15 is set to be shifted downstream from the opening 11 (left side in FIG. 1).

  If the bottom plate 22 provided in the counterweight 20 is set long, the cut tobacco TA received from the trough 10 can be continuously conveyed to the downstream side. However, the vibrating conveyor apparatus 1A is provided with a bottom plate 22 in the counterweight 20 only in a region that receives the cut tobacco TA falling from the opening 11. That is, as shown in FIG. 1, the first embodiment shows an example in which the counterweight 20 chops the cigarette TA and then drops it further while being unfolded. In FIG. 1, the bottom plate 22 is formed as a triangular deployment receiving portion, and the other region is a triangular opening 23. Therefore, the chopped tobacco TA that has fallen from the top can be dropped further down while being efficiently deployed. In FIG. 1, the bottom plate 22 is hatched so that it can be easily confirmed.

  When the above structure is employed, the cut tobacco TA can be dropped to an arbitrary location even in the middle of the trough 10. Therefore, even if a long trough is set, the conveyed object can be supplied to an arbitrary place as necessary.

  1 shows a structure example in which one opening 11 is provided in the trough 10 to drop the chopped cigarette TA, and the counterweight 20 side that receives this is immediately dropped, but the structure is limited to such a structure. Not necessary. That is, a plurality of openings 11 may be provided in the trough 10 in accordance with a request from the site where the vibration conveyor device 1A is installed. Further, it is not essential that the development receiving portion (bottom plate 22) provided on the counterweight 20 side is formed at the same position as the opening 11. The development receiving portion may be set so as to be shifted downstream from the opening 11 as necessary.

  Incidentally, the structure illustrated in FIG. 1 illustrates a structure in which the cigarette TA is dropped immediately below the opening 11 of the trough 10. It is preferable that the transported object such as the cigarette TA is unfolded (in an unfolded state) and dropped so as not to be in a lump state in addition to preventing scattering to the periphery. Therefore, it is necessary to provide a deployment structure for deploying the cut tobacco together with a chute structure for preventing jumping and scattering. However, many parts such as the hinge arm 3 and the excitation spring 7 are arranged between the trough and the counterweight as described above. For this reason, when the chute structure and the unfolded structure are formed integrally, it generally interferes with the surrounding structure.

  However, in the case of the present embodiment, as described above, since only the chute 15 is disposed between the trough 10 and the counterweight 20, it is possible to avoid the interference with the surrounding structure. Then, the chopped tobacco TA that has fallen is unfolded by the bottom plate 22 serving as a unfolding receiving portion provided in the counterweight 20. Therefore, the structure shown in the first embodiment discloses a preferable structure in the case where it is desired to drop the object to be transported while developing just below the opening.

  In the vibrating conveyor device 1A of the first embodiment described above, the opening 11 is provided in the trough 10, and this opening is opened and closed by the shutter 12, so that the cut tobacco TA can be conveyed to an arbitrary position. Therefore, a to-be-conveyed object can be supplied to several places with one vibration conveyor apparatus, without deploying a plurality of vibration conveyor apparatuses. If the opening 11 is increased as necessary, the cigarette TA can be supplied in a plurality of arbitrary locations. Further, the vibrating conveyor apparatus 1A can drop the cut tobacco TA using the vibration of the counterweight 20 arranged on the lower side, so that the cut tobacco TA is not formed into a lump just below the opening 11. Can supply.

  Another embodiment according to the present invention will be further described with reference to the drawings. FIG. 3 is a perspective view illustrating an appearance of the vibrating conveyor device 1B according to the second embodiment. In addition, the same code | symbol is attached | subjected to the site | part similar to the vibration conveyor apparatus 1A of Example 1 in order to avoid the overlapping description.

  In the vibrating conveyor apparatus 1B, a wire mesh 40 functioning as a sieve is set on the trough 10. Therefore, when the object to be conveyed PR is a mixture of objects of different sizes, the size of the mesh of the wire mesh 40 is set in advance to a predetermined size, so that objects including sizes are selected and conveyed. it can.

  FIG. 3 shows a case where a small conveyed object PR-S that has passed through the wire mesh 40 is supplied to the downstream end of the trough 10 and downward from the opening 11. According to this vibration conveyor apparatus 1B, when handling the to-be-conveyed object with which the object from which a magnitude | size differs is mixed, it can convey, selecting. In the structure illustrated in FIG. 3, the large conveyed object PR-B conveyed on the wire mesh 40 to the downstream end 40TE and the small conveyed object PR-S conveyed below the metal mesh 40 to the downstream end are downstream. It forms so that it may discharge | emit from the drop port 41 provided in the edge. A chute for the object to be conveyed PR-B and a chute for the object to be conveyed PR-S are formed independently in the pit 41. By adopting such a structure, a large conveyed object PR-B can be conveyed to the downstream end on the wire mesh 40, and for the small conveyed object PR-S, the shutter 12 is opened and closed as shown in the figure. By doing so, it can be dropped or conveyed to the downstream end. A structure in which the downstream end 40TE of the wire mesh 40 is closed may be employed. In this case, the selected large conveyed product PR-B can be left on the wire mesh 40.

  In the vibrating conveyor device 1B of the second embodiment described above, since the wire mesh 40 is disposed on the trough 10, only the conveyed object PR-2 having a predetermined size or less that has passed therethrough can be selected and conveyed. . For example, when handling a transported object in which branches, leaves, etc. are mixed with the seeds of agricultural products, the use of the vibration conveyor device 1B can supply only necessary seeds to an arbitrary position while removing unnecessary portions. Of course, this vibration conveyor apparatus 1B can be used also in the case of separating the objects to be conveyed PR having a size and conveying them to necessary places.

  1 and 3 show a case where the triangular opening 23 provided in the bottom plate 22 of the counterweight 20 is opened. In this case, all the objects to be conveyed are dropped. The vibration conveyor devices 1A and 1B may be modified so that the opening 23 is opened and closed by providing a shutter in the same manner as the trough 10. By providing the shutter in this way, it can be changed so that it can be opened when necessary to drop an object to be transported, and can be further transported downstream by a trough when closed.

  Furthermore, as a modification of the vibration conveyor device 1B, a structure in which a wire mesh is also arranged on the bottom plate 22 may be adopted. In the structure shown in FIG. 3, when a wire mesh whose mesh size is smaller than the wire mesh 40 is added on the bottom plate 22, the conveyed object can be sorted into three sizes of large, medium and small. Further, as a modification of the vibration conveyor device 1A, a structure in which a wire mesh is arranged on the bottom plate 22 may be adopted.

  FIGS. 4A and 4B are diagrams illustrating the vibration conveyor device 1 </ b> C according to the third embodiment. FIG. 4A is a plan view of the device, and FIG. 4B is a side view. FIG. 4 shows a simplified configuration. The main part of the configuration is the same as that of the vibrating conveyor apparatus 1A shown in FIG. 1, and the corresponding parts are denoted by the same reference numerals.

  This vibrating conveyor device 1C is further provided with a damming plate 45 and an actuator 46 for rotating the damming plate 45 as conveyance stop means on the upstream side of the opening 11 so as to dam the object to be conveyed PR. In some cases, it is desired to close the shutter 12 in order to switch to conveyance on the trough 10 after the object PR is dropped from the opening 11 with the shutter 12 opened. At this time, the conveyed product PR may be sandwiched between the trough 10 and the shutter 12.

  Since this vibrating conveyor apparatus 1C can dam the conveyed object PR as necessary, it is possible to prevent the conveyed object PR from being caught. Specifically, when the shutter 12 is switched from open to closed, the conveyed object PR is first dammed by the damming plate 45 and then the shutter 12 is closed. In this way, it is possible to reliably prevent the object PR from being caught. Further, according to the vibrating conveyor device 1C, the downstream side can be emptied if the conveyed object is dammed when the conveyed object to be supplied is switched or when cleaning is performed. Therefore, the intended work can be performed efficiently. Of course, you may apply the structure of this Example 3 to the vibration conveyor apparatus 1B of Example 2 which has arrange | positioned the metal mesh 40 to the trough 10. FIG.

  FIGS. 5A and 5B are diagrams illustrating the vibrating conveyor device 1D according to the fourth embodiment, in which FIG. 5A is a plan view of the device and FIG. 5B is a side view thereof. FIG. 5 also shows a simplified configuration. The main part of the configuration is the same as that of the vibrating conveyor apparatus 1A shown in FIG. 1, and the corresponding parts are denoted by the same reference numerals.

  In the vibration conveyor device 1D, the opening 11 is provided close to one side in the width direction WD. And as shown in FIG. 5, it is more preferable to arrange | position the partition plate 47 in the side part of the opening 11, and to isolate | separate the side which passes the opening 11, and the non-passing side. This vibration conveyor apparatus 1D can drop a part of the conveyed object PR being conveyed when the shutter 12 is opened. When the object to be conveyed is roughly divided into the trough 10 side and the counterweight 20 side, the object to be conveyed can be easily selected if the shutter 12 is kept open. In this case, since it is not necessary to frequently open and close the shutter 12, the driving power can be reduced.

  Although the vibration conveyor device 1D according to the fourth embodiment includes the shutter 12 in the opening 11 as a preferable structural example, the vibration conveyor device 1D may have a structure in which the shutter 12 is omitted. For example, in a vibrating conveyor apparatus that is employed in a factory or the like that always divides a predetermined object to be conveyed and supplies it to a predetermined location, the opening is not closed in a steady state, so there is no need to provide a shutter. On the other hand, by adjusting the shape and size of the openings provided in the trough and the positional relationship with other openings, the supply amount is roughly supplied to each opening while conveying the object to be conveyed even when multiple openings are open. Can be supplied. And since this vibration conveyor apparatus can simplify a structure compared with the vibration conveyor apparatus of the Example mentioned above, it can reduce cost.

  In addition, you may further apply the metal-mesh 40 employ | adopted with the vibration conveyor apparatus 1B of Example 2 mentioned above to the structure of the vibration conveyor apparatus of the said Example 4. FIG. Similarly, a damming plate 45 provided upstream of the opening 11 employed in the vibration conveyor device 1C of the third embodiment may be further applied.

  Since the opening 11 is formed in the trough 10, the vibration conveyor apparatus of the Example demonstrated above can supply a to-be-conveyed object in the middle position which has arrange | positioned the trough 10. FIG. Even in the case where the trough 10 is set to be long, it is possible to supply an object to be conveyed with an opening provided at an arbitrary position. Moreover, by providing the shutter 12 in the opening, the opening can be opened and closed as necessary, and the conveyance mode of the object to be conveyed can be switched. Therefore, facilities can be simplified compared with the case where a plurality of vibrating conveyor devices are conventionally arranged and the objects to be conveyed are supplied to a plurality of locations. In addition, since the vibrating conveyor device of the embodiment has a structure in which the trough 10 is on and the counterweight 20 is on the bottom, the device is excellent in maintenance that facilitates maintenance work.

  In addition, since the counterweight 20 disposed under the trough functions as the second trough, the object to be transported can be further transported or dropped while being unfolded as necessary. Such a vibrating conveyor device can be applied to various fields. In the above, in the case of chopped tobacco, the case of transporting agricultural seeds has been described, but it is suitable for transporting tea or coffee, transporting wood chips, finely cut paper scraps, and the like. Furthermore, since it can convey while sorting by arrange | positioning a metal-mesh, it can respond also to the case where it is desired to sort the to-be-conveyed object which is large and small, or to separate the mixed unnecessary thing.

  The preferred embodiment of the present invention has been described in detail above. However, the present invention is not limited to the specific embodiment, and various modifications can be made within the scope of the gist of the present invention described in the claims. Deformation / change is possible.
