Description

  The present invention relates to a vibration transfer device that can transfer a transfer object in a predetermined direction by vibration.

  Conventionally, the trough has a trough shape (groove shape) extending in the transport direction, a transport surface arranged inside the trough, and vibration applying means for vibrating the trough, and transported by vibrating the trough by the vibration applying means. There is known a vibration transfer device configured to vibrate a surface so that a transfer object on a transfer surface can be transferred in a predetermined transfer direction.

  The object to be conveyed is applied to the object to be conveyed on the conveying surface having a large number of holes as the vibration conveying device by applying hot air or cold air sent from the lower side of the conveying surface to the conveying surface through the hole. It is known that can be dried or cooled (see Patent Document 1). In such a vibration transfer apparatus, the transfer object is uniformly fluidized by the vibration action and the air blowing effect, and it is possible to uniformly dry and cool each transfer object.

  Here, hot air or cold air flowing on the vibration conveyance through a large number of holes opened in the conveyance surface is sent from the side perpendicular to the conveyance direction below the conveyance surface. In the vibration conveying device, a blower that feeds hot air or cold air has to be disposed below the conveying surface because a tray (for example, the bottom wall of the trough) and vibration imparting means that accommodates fragments and dust that have fallen from the conveying surface must be disposed below the conveying surface. It is difficult in terms of design to dispose the fan directly below the transport surface, and as described above, the blower is set to be fed from the side perpendicular to the transport direction below the transport surface.

JP 2011-214735 A

  By the way, the conveyance surface which conveys a conveyance target object while vibrating is formed of the plate-shaped member (perforated plate) which has many holes. Patent Document 1 exemplifies a mode in which the conveyance surface is configured by a perforated plate in which a large number of holes are formed by, for example, cutting press processing. When such a perforated plate is applied, it is possible to vary the opening direction of each hole, for example, for each predetermined region of the conveying surface by a cut press process, and air or cold air flowing into the conveying surface through each hole. The flow can be changed in the opening direction of the holes.

  On the other hand, from the viewpoint of ease of processing and cost reduction, there is also known an aspect in which the conveyance surface is formed by punching metal in which a large number of holes are formed by punching. The holes formed in the punching metal are all opened in the thickness direction, and the flow of air or cold air flowing into the transport surface through such holes is the opening direction of the holes, that is, the thickness direction of the punching metal. Become.

  In the vibration transfer device in which the transfer surface is formed of such punching metal, abnormal noise may occur in the operating state of the blower.

  As a result of verification to investigate the cause of this abnormal noise, the present inventor has found that air blow or cold air is generated when passing through the hole of the punching metal. Further, the present inventor confirmed that the air sent by the blower from below the punching metal hits the hole obliquely from below with respect to the opening direction of the hole (thickness direction of the punching metal), and the inlet (lower end opening edge) and outlet (upper end) of the hole It has been clarified that the occurrence of air vortices at the opening edge is the root cause of abnormal noise generation.

  The present invention has been made paying attention to the occurrence of such problems, and the main purpose thereof is a function of performing an appropriate drying process or cooling process while transporting a transport object on a transport surface in a predetermined direction. An object of the present invention is to provide a vibration transfer device capable of preventing and suppressing the generation of abnormal noise in the operating state of a blower without damaging it.

  That is, the present invention includes a punching metal that forms a transport surface capable of transporting an object to be transported in a predetermined transport direction and has a large number of holes opened in a thickness direction, a vibration applying unit that vibrates the punching metal, and a punching A vibration transfer device including a blower that blows gas in a direction orthogonal to or substantially perpendicular to the conveyance direction from the side below the metal, and the flow of gas blown from the blower is directly below the punching metal. A rectifying member for converting the flow into a flow parallel or substantially parallel to the thickness direction of the punching metal is arranged.

  Here, examples of the object to be transported in the present invention include powders (including cereals), chemicals, crushed stones, and the like (powder particles). Good. In addition, the vibration applying unit in the present invention may be any one that directly gives vibration to the punching metal or that that indirectly gives vibration to the punching metal. Further, examples of the “gas” in the present invention include air (including dry air) and inert gas, and the temperature of the gas depends on the process to be performed on the object to be transported, that is, the drying process or the cooling process. An appropriate value is set.

  With such a vibration transfer device, the gas blown by the blower from the side below the punching metal passes through the rectifying member at a point before passing through the hole of the punching metal, and this rectification By converting the gas flow into a flow parallel or substantially parallel to the thickness direction of the punching metal by the member, the gas flow passing through the hole becomes a flow parallel or substantially parallel to the opening direction of the hole. Therefore, in the case of the vibration transfer device of the present invention, the probability that the gas blown by the blower from the side below the punching metal hits the hole obliquely from below with respect to the opening direction of each hole of the punching metal is zero to zero. It can be reduced to a close value, and it is possible to prevent / suppress the generation of gas vortices at the inlet (lower opening edge) and outlet (upper opening edge) of the hole. Can be prevented / suppressed. Moreover, an appropriate process (drying process or cooling process) can be appropriately performed on the object to be transported by the gas flowing on the transport surface through the hole of the punching metal, and the gas is transported on the transport surface. By promoting the fluidization of the object, it is possible to realize a vibration conveyance device that does not cause drying unevenness or cooling unevenness or hardly occurs.

  In particular, a preferred embodiment of the rectifying member in the present invention is configured using at least one of a porous three-dimensional nonwoven fabric in which fibers are overlapped and bonded to a three-dimensional structure, or a foam having an open cell structure. Things can be mentioned. Both the three-dimensional nonwoven fabric and the open-cell structure foam are porous materials, and in the vibration conveying device according to the present invention, the roughness (mesh size) of the rectifying member made of such a porous material is punched. Since the opening area of each hole in the metal is larger than the opening area of the metal, the fragments and dust of the object to be transported that have fallen below the punching metal through the hole in the punching metal are captured and retained by the rectifying member. Occurrence of clogging can be avoided. In addition, it is also possible to comprise a rectification | straightening member using both the three-dimensional nonwoven fabric and the foam of an open cell structure.

  In addition, if the vibration conveyance device of the present invention is provided with a holding member that holds the rectifying member, the rectifying member is prevented from moving or dropping from a regular arrangement location by vibration of the vibration applying unit, An appropriate mounting state of the rectifying member can be maintained.

  According to the vibration transfer device of the present invention, the transfer surface is provided immediately below the punching metal by converting the flow of the gas blown from the blower into a flow parallel to or substantially parallel to the thickness direction of the punching metal. An appropriate drying process or cooling process can be performed while conveying the upper conveyance object in a predetermined direction, and the occurrence of abnormal noise in the operating state of the blower can be prevented / suppressed.

Here, the hole P1 of the punching metal P has such a size that a regular-size transport object cannot pass (cannot be dropped). In addition, since each hole P1 is sufficiently small with respect to the whole dimension of the punching metal P, the hole P1 is omitted in FIG. The punching metal P of the present embodiment includes a horizontal portion P2 that is substantially parallel to the bottom wall 32 of the trough 3, and a mounting portion P3 that rises obliquely upward from both side edges of the horizontal portion P2 and extends in the vertical direction in the vicinity of the upper end portion. (See FIG. 2), a large number of holes P1 are formed in a predetermined region of the horizontal portion P2 (a region that functions as a conveyance path (conveying surface T) of an object to be conveyed), and the attachment portion P3 is connected to the side wall 31 of the trough 3. Are fixed by appropriate fixing means (FIG. 2 shows an example of bolt tightening). The punching metal P is made of, for example, a metal material, and an appropriate material such as stainless steel or titanium can be selected according to the type of the conveyance object.

  In the present embodiment, as shown in FIG. 1, a discharge port 33 for discharging the object to be transported out of the trough 3 is formed at the downstream end in the transport direction A of the trough 3. In addition, a plurality of air supply ports 34 are formed at predetermined intervals on any one of the side walls 31 of the trough 3. The air supply port 34 is formed at a position lower than the attachment position of the punching metal P on the side wall 31 of the trough 3. The vibration transfer device X of the present embodiment is configured to send a predetermined gas supplied from the blower 2 through each air supply port 34 to the inner space of the trough 3 and to the lower region PU of the punching metal P. . In FIGS. 2 and 3, the flow of gas sent from the air supply port 34 to the lower region PU of the punching metal P is schematically shown by arrows.

  In the present embodiment, among the plurality of air supply ports 34 arranged in the transport direction A, the air supply ports 34 on the upstream side in the transport direction A (in FIG. 1, three of the five air supply ports 34 on the upstream side in the transport direction A). The hot air can be supplied from the blower 2 connected to the air inlet 34), and the two air supply ports 34 on the downstream side in the conveying direction A among the five air inlets 34 in FIG. Cold air can be supplied from the blower 2 connected to the air vent 34). The number of blowers 2 can be selected as appropriate according to the type of gas to be blown (temperature or type of gas itself). In FIG. 1, the common blower 2 connected to each hot air supply port 34, The vibration conveying apparatus X provided with the total of 2 units | sets of the supply air blower 2 connected to the cold air supply port 34 is illustrated. The relative number of the hot air supply ports 34 and the cold air supply ports 34 and the arrangement order along the conveyance direction A (whether the hot air supply ports 34 are upstream of the cold air supply port 34 in the conveyance direction A) Selection of the direction A downstream side) can be appropriately set or changed. Examples of the gas applicable in the present embodiment include air (including dry air) and inert gas. The temperature of the gas is appropriately determined depending on the process to be performed on the object to be transported, that is, the drying process or the cooling process. Is set to the value of Further, an inspection window 35 that is an internal space of the trough and is accessible to the lower region PU of the punching metal P is formed on the side wall 31 of the trough 3 (see FIG. 1). The inspection window 35 is opened when the lower area PU of the punching metal P is accessed, and is normally closed.

  In addition, at the upstream end of the hood 4 in the transport direction A, for example, a feed for feeding a transport target supplied from a transport target supply machine 6 provided with a hopper 61 or the like to the upstream end of the punching metal P in the transport direction A. A mouth 41 is formed. The hood 4 is formed with a plurality of exhaust ports 42 that open upward. These exhaust ports 42 are connected to the exhaust fan 8 via, for example, the dust collector 7, and the gas supplied from the air supply port 34 and used for the drying process and the cooling process of the object to be transported on the transport surface T is the main body. 1 For discharging outside. Although FIG. 1 illustrates a configuration in which four exhaust ports 42 are formed, the number of exhaust ports 42 can be appropriately selected according to the number of air supply ports 34 and the size of the conveyance surface T. Further, an inspection window 43 that is accessible on the inner space of the hood 4 and the conveying surface T is formed on the side surface of the hood 4. The inspection window 43 is opened when accessing the internal space of the hood 4 and the transport surface T, and is closed during normal times.

  And the vibration conveyance apparatus X of this embodiment is parallel or substantially parallel to the thickness direction of the punching metal P in the flow direction of the gas blown from the air blower 2 just under the punching metal P, as shown in FIG.2 and FIG.3. The rectifying member 9 for converting into a simple flow is arranged. In FIG. 2, the entire rectifying member 9 is shown with a predetermined pattern.

  In this embodiment, as shown in FIG. 3, a rectifying member 9 constituted by a porous three-dimensional nonwoven fabric in which fibers are overlapped and bonded in a three-dimensional structure is applied. As a specific example of such a rectifying member 9, a large space in which a large number of elastic bodies obtained by curling Saran fibers in a spring shape are coated and bonded to each other so that columns of Saran (registered trademark) fibers are randomly arranged vertically and horizontally. Mention may be made of a three-dimensional nonwoven fabric having a rate. Moreover, in the vibration conveyance apparatus X of this embodiment, the rectification | straightening member 9 with a larger roughness than the opening area of each hole P1 of the punching metal P is applied. In the vibration conveyance device X of the present embodiment, such a rectifying member 9 is disposed at a position covering the entire downward surface Pb of the punching metal P. The thickness dimension of the rectifying member 9 (dimension in the direction coinciding with the opening direction PA of the hole P1 in the state of being arranged immediately below the punching metal P) can be set to an appropriate value. For example, it is also possible to arrange a plurality of types of rectifying members 9 having different eye roughness in a state of being laminated in an appropriate order in the thickness direction. Of the rectifying member 9, the portion facing the downward surface Pb of the punching metal P (when this portion is regarded as the front surface of the rectifying member 9) is preferably in contact with the downward surface Pb of the punching metal P. The punching metal P may be slightly separated from the downward surface Pb. The pressure loss of the gas passing through the rectifying member 9 is determined by the thickness dimension of the rectifying member 9 and the roughness of the eyes.

  Moreover, the vibration conveyance apparatus X of this embodiment is provided with the holding member H which hold | maintains the rectification member 9, as shown in FIG.2 and FIG.3. In the present embodiment, the holding member H is constituted by a wire mesh whose mesh weight is coarser than that of the rectifying member 9. The holding member H has a surface far from the downward surface Pb of the punching metal P in the thickness direction of the rectifying member 9 (when the surface facing the downward surface Pb of the punching metal P is regarded as the front surface of the rectifying member 9, (The back surface of P) is held from below, and a desired gap dimension in the height direction between the downward surface Pb of the punching metal P and the holding member H is maintained, thereby ensuring an appropriate arrangement space for the rectifying member 9. ing. The holding member H is fixed to the side wall 31 of the trough 3 by appropriate fixing means (bolt or adhesion, welding, etc.) on both side edges.

  Next, the operation of the vibration transfer device X having such a configuration will be described.

  In the vibration transfer device X of the present embodiment, by rotating the motor 52, the crank pulley 53 connected to the motor 52 via the belt rotates, and is connected to the crank pulley 53 as the crank pulley 53 rotates. The vibration transmission member 54 that is being operated swings. This swing is transmitted to the trough 3, and the trough 3 vibrates. Here, the inclined spring 59 and the connecting member 55 shown in FIG. 1 exhibit the function of resonating the trough 3 while restricting the movement of the trough 3. The counterweight 51 also vibrates due to the reaction force from the trough 3, but the vibration of the counterweight 51 is transmitted to the base 56 by the damping spring 57 provided between the base 56 and the frame 58. It can be prevented / suppressed. The vibration conveyance device X of the present embodiment vibrates the entire trough 3 by the action of the vibration applying unit 5 and also supplies air from the blower 2 to the air supply port 34 (hot air supply port 34, cold air supply port 34). Gas (hot air, cold air) is circulated through the interior space of the trough 3 through the air. The flow rate of the gas supplied from each air supply port 34 can be set as appropriate in consideration of the type of the granular material, the temperature of the gas, the volume of the main body 1, and the like.

  In this state, the vibration transfer device X of the present embodiment inputs (supplies) the transfer object from the transfer object supply unit 6 to the transfer surface T that is the upward surface Pa of the punching metal P through the input port 41. The conveyance object landed on the conveyance surface T is conveyed toward the conveyance direction A by the force caused by the vibration of the conveyance surface T, that is, the force of the component in the conveyance direction A that coincides with the vibration direction by the vibration applying unit 5. 3 is discharged out of the trough 3 through a discharge port 33 formed at the downstream end in the conveying direction A. In the vibration transfer device X, it is preferable to continuously supply a conveyance target for a predetermined flow rate from the input port 41, but it is also possible to set so that a conveyance target for a predetermined flow rate is supplied at regular intervals. is there.

  The vibration transfer device X of the present embodiment applies hot air or cold air to be supplied from the air supply port 34 (hot air supply port 34, cold air supply port 34) to the object being transferred on the transfer surface T. It is possible to perform a drying process and a cooling process by applying the air, and by blowing these hot air and cold air, the fluidization of the transport object is promoted in combination with the vibration of the transport surface T. It is possible to prevent a situation of staying on the transport surface T and to smoothly transport the transport object on the transport surface T to the discharge port 33 at a constant transport speed. That is, according to the transport vibration device according to the present embodiment, it is possible to improve the efficiency of an appropriate process (drying process or cooling process) using gas and to increase the processing efficiency of transporting the transport target.

  By the way, as shown in FIGS. 2 and 3, the gas fed into the trough 3 from the air supply port 34 (hot air supply port 34, cold air supply port 34) formed in the side wall 31 of the trough 3 is punched. In the lower region PU of the metal P, the airflow is in a direction (width direction of the transfer surface T) orthogonal to or substantially orthogonal to the transfer direction A of the transfer object. Such gas passes through the hole P1 of the punching metal P from below the punching metal P, and is exhausted out of the main body 1 through the exhaust port 42 formed above the punching metal P. When the present inventors adopt a configuration in which such gas enters the hole P1 of the punching metal P obliquely from below and passes through the hole P1, as shown in FIG. At the inlet P1a and outlet P1b (lower opening edge, upper opening edge) of the hole P1, air flow vortices (shown in a spiral diagram in FIG. 4) are generated, and it is determined that abnormal noise is generated. In order to prevent the occurrence of problems, the inventors have come up with a configuration in which the rectifying member 9 having the above-described configuration is disposed at a position in contact with or close to the downward surface Pb of the punching metal P.

  The rectifying member 9 of the present embodiment is configured using a three-dimensional non-woven fabric as described above, and is punched by being fed from each air supply port 34 (hot air supply port 34, cold air supply port 34). When the gas toward each hole P1 of the metal P passes through the rectifying member 9, each fiber can define a space that is randomly formed inside the rectifying member 9 due to the nature of the gas that follows the least resistant path. It follows the path | route which does not hit, and arrives at the hole P1. Therefore, as shown in FIG. 3, the gas flow in the oblique direction with respect to the opening direction PA of the punching metal P (the thickness direction of the punching metal P) is rectified before the time when it reaches the rectifying member 9. By passing through the member 9, the flow is converted into a flow parallel or substantially parallel to the opening direction PA of the punching metal P immediately before entering the hole P <b> 1 of the gas punching metal P. As a result, the gas flows straight along the opening direction PA of the hole P1 of the punching metal P, and it is possible to avoid a situation where a gas vortex is generated at the inlet P1a and the outlet P1b of the hole P1 of the punching metal P. Generation of sound can be prevented. Moreover, the vibration transfer device X of the present embodiment can appropriately perform an appropriate process (drying process or cooling process) on the transfer target object by the gas flowing on the transfer surface T through the hole P1 of the punching metal P. This gas promotes fluidization of the conveyance object conveyed on the conveyance surface T, so that drying unevenness and cooling unevenness do not occur or hardly occur, and an excellent function is exhibited also in this respect.

  As described above, the vibration transfer device X according to this embodiment is configured so that the flow of gas blown from the blower 2 is parallel or substantially parallel to the thickness direction of the punching metal P immediately below the punching metal P forming the transfer surface T. Since the rectifying member 9 for converting into a flow is arranged, the gas flow blown by the blower 2 from the side below the punching metal P is punched at a point before passing through the hole P1 of the punching metal P. The flow can be converted into a flow parallel or substantially parallel to the thickness direction of the metal P, and the flow of gas passing through the hole P1 can be changed to a flow parallel or substantially parallel to the opening direction PA of the hole P1. Thereby, the probability that the gas blown by the blower 2 hits the hole P1 obliquely from below with respect to the opening direction PA of each hole P1 of the punching metal P can be reduced to zero or a value close to zero. It is possible to prevent / suppress the generation of gas vortices at the inlet P1a and the outlet P1b, and to prevent / suppress the generation of abnormal noise in the operating state of the blower 2.

  In particular, the vibration conveyance device X according to the present embodiment uses a porous three-dimensional nonwoven fabric in which fibers are superposed and bonded in a three-dimensional structure as the rectifying member 9, and the eyes of the three-dimensional nonwoven fabric that is a porous material are used. Since the roughness is larger than the opening area of each hole P1 of the punching metal P, a piece of the conveyance object dropped from the conveyance surface T to the lower side of the punching metal P through the hole P1 of the punching metal P, or a normal size. It is possible to avoid the occurrence of clogging caused by the non-conveyed object itself or the dust on the conveying surface T being caught by the rectifying member 9 and staying there. In the vibration transfer device X of the present embodiment, the hole P1 of the punching metal P and the eyes of the rectifying member 9 pass through and fall onto the bottom wall 32 of the trough 3, and can be collected by an appropriate defective product collecting means (collecting unit). It is possible to configure.

  In addition, since the vibration conveyance device X of the present embodiment includes the holding member H that holds the rectifying member 9, the rectification is performed by the vibration of the vibration applying unit 5 and the pressure of the gas blown from the side of the trough 3. The member 9 can be prevented from moving or dropping from the regular arrangement location, and the proper arrangement state of the rectifying member 9 can be maintained.

  In addition, this invention is not limited to embodiment mentioned above. For example, the size (opening area) and shape (not limited to round holes) and the arrangement pattern of punching metal holes can be changed as appropriate, and the size, shape and arrangement pattern of the holes can be set at random. . The punching metal material is preferably a steel material, but a punching metal formed from a material other than the steel material may be employed.

  In the above-described embodiment, the three-dimensional nonwoven fabric in which fibers are overlapped and bonded to the three-dimensional structure is exemplified as the rectifying member, but the rectifying member made of a foam (urethane foam or the like) having an open cell structure, or the tertiary A rectifying member configured by combining an original non-woven fabric and a foam having an open cell structure can be applied.

  Further, in order to arrange the rectifying member directly under the punching metal, instead of or in addition to the configuration in which the rectifying member is held by the holding member, a predetermined portion of the rectifying member (a gas flow path toward the hole is not obstructed). A configuration in which the adhesive is applied to the punching metal with an adhesive applied to (range) may be adopted.

  In addition, the objects to be transported that can be transported by the vibration transport device of the present invention are all powder raw materials including food, chemicals, steel, crushed stones, foods, chemicals, metals, ceramics, etc., and are not particularly limited. Absent. Moreover, what is necessary is just to set suitably the opening area of the hole of a punching metal, and the roughness of the fabric weight of a rectification | straightening member according to the size per one conveyance object.

  Further, in the above-described embodiment, the vibration applying unit is exemplified to vibrate the punching metal by vibrating the entire trough. However, if the design is possible, the vibration applying unit can directly vibrate the punching metal itself. May be applied. As the vibration applying unit, a forced vibration type can be applied instead of the resonance vibration type shown in the above embodiment.

  The vibration transfer device of the present invention may exhibit only one of a drying processing function or a cooling processing function for a transfer target object.

  In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
