Abstract

The present invention provides a conveyor-type drying apparatus requiring little installation space and having high drying efficiency. A conveyor device (1a) of the conveyor-type drying apparatus is configured such that a conveyor surface is formed by a plurality of plates (30) that move with the rotation of an endless chain (20). A driven gear (60) meshing with the endless chain is provided separately from a first sprocket (11) and a second sprocket around which the endless chain is wound, and knockers (65) protrude from the driven gear. The rotation trajectory of the knockers intersects the trajectory of a plate if the plate, which should pivot about a first shaft (21) when movement of the plate toward the first sprocket causes a guide roller (40) to run off an edge of an upper rail (51), is moving without pivoting about the first shaft. As a result, the knocker collides with the plate that has been prevented from pivoting about the first shaft and causes the plate to pivot.

Description

Conveying dryer

The present invention relates to a conveying type drying apparatus that dries while conveying an object to be dried by a conveyor.

In the past, the present applicant has proposed and implemented many drying apparatuses using a conveyor belt (see, for example, Patent Documents 1 and 2). In these, a plurality of conveyor belts are arranged vertically and the traveling directions of adjacent conveyor belts are reversed. The material to be dried supplied on the uppermost conveyor belt is transported to the end of the conveyor belt and falls onto the next conveyor belt as the belt rotates. By repeating this, the material to be dried is dried by the air sent between the conveyor belts before being discharged from the lowermost conveyor belt. In such a drying apparatus, since the several conveyor belt is distribute | arranged up and down, it has the advantage that the space for installation is small.

As a result of further study by the applicant, the present invention has achieved a transport-type drying apparatus having a smaller installation space and higher drying efficiency by means different from the above-described conventional apparatus. It is a thing.

JP 2001-174153 A Japanese Patent Laid-Open No. 10-327695

As described above, an object of the present invention is to provide a transport type drying apparatus having a small installation space and high drying efficiency.

In order to solve the above problems, the transport-type drying apparatus according to the present invention is:
“A transporting drying device that includes a transporting device that transports an object to be dried containing moisture, and a ventilating device that circulates air through the space in the transporting device,
The transfer device
A pair of endless chains;
One end of each of the pair of endless chains is wound around and the pair of first sprockets rotating the endless chain from top to bottom, and the pair of first sprockets are horizontally separated from each other, and each of the pair of endless chains A pair of second sprockets, the other end of which is wound to rotate the endless chain from below to above,
Located between a pair of the endless chains, each of which is attached to both of the endless chains so as to be rotatable around a first axis parallel to the width direction. A plurality of plates forming a conveying surface to be
A pair of guide rollers rotatably supported around a second axis separated from the first axis at both side surfaces of each of the plurality of plates;
A pair of guide rollers extending in a horizontal direction between the first sprocket and the second sprocket and moving the plate from the second sprocket toward the first sprocket by rotation of the pair of endless chains. A pair of upper rails that guide each roll and hold the plate horizontally;
A pair of the guide rollers extending horizontally between the first sprocket and the second sprocket, and when the plate moves from the first sprocket toward the second sprocket by the rotation of the pair of endless chains. A pair of lower rails that guide each roll and hold the plate horizontally;
A driven gear that is positioned above the endless chain between the first sprocket and the end of the upper rail and rotates with the rotation of the endless chain by meshing with the endless chain;
A knocker that protrudes from the driven gear and rotates with the driven gear, and when the plate moves toward the first sprocket, the first shaft is in front of the second shaft. When the guide roller is removed from the end of the upper rail, the plate rotates downward about the first axis, and the guide roller is guided to the lower rail as the endless chain rotates. Accordingly, the plate rotates upward around the first axis, and when the plate moves toward the second sprocket, the first axis is located behind the second axis, and the guide roller When the plate is removed from the end of the lower rail, the plate rotates downward about the first axis, and the guide roller is guided to the upper rail as the endless chain rotates. Wherein the Rukoto plate is intended to rotate upward about the first axis,
The rotation trajectory of the knocker moves when the guide roller moves away from the end of the upper rail due to the movement of the plate toward the first sprocket while the rotation around the first axis is prevented. Intersects the trajectory of the plate.

“Dried matter containing moisture” has no problem in dropping in the process of drying, and examples thereof include livestock excrement, compost, sludge, and food residues.

As the “ventilator”, it is possible to use a blower that sends air into the space in the transfer device, a blower that draws air by discharging air from the space in the transfer device, or both.

"A knocker protruding from the driven gear" can be provided in a plurality depending on the relationship between the size of the driven gear and the length of the plate in the traveling direction.

With the above configuration, in the transport apparatus of the present invention, a transport surface on which an object to be dried is placed is formed by a plurality of plates that move as the endless chain circulates. As will be described in detail later, when the plate moves along the first sprocket and moves along the second sprocket, the plate rotates downward around the first axis by its own weight. As a result, the plate circulates between the first sprocket and the second sprocket while always forming the conveying surface on the same surface.

Then, the object to be dried conveyed by the plate moving from the second sprocket toward the first sprocket falls as the plate rotates around the first axis in the vicinity of the first sprocket. The fallen object to be dried is placed on a plate moving from the first sprocket toward the second sprocket below, and further conveyed toward the second sprocket. In the process of being transported by the plate in this way, the material to be dried is dried by the air flowing through the space in the transport device by the ventilation device. Since the object to be dried that has been transported to the vicinity of the second sprocket falls as the plate rotates around the first axis, the object to be dried that has been dried under the transport device can be collected.

In the transport type drying apparatus of this configuration, the object to be dried is placed on the plate and transported. Unlike a conveyor belt that requires flexibility, the plate can be formed of a highly rigid material such as metal or resin. As a result, compared with the case of using a conveyor belt, the object to be dried can be transported with elements having high load resistance and mechanical strength, and therefore it is possible to transport a large amount of object to be dried at a time. , Can be dried efficiently.

Also, in a drying apparatus using a conveyor belt, after the conveyor belt that has reached one of the pair of sprockets wound around the conveyor belt rotates from top to bottom, it reaches the other sprocket and rotates from bottom to top In the process of movement, the object to be dried cannot be transported. In other words, the endless conveyor belt can dry the object to be dried only in one way. On the other hand, in the transport type drying apparatus of this configuration, the object to be dried is both in the process of moving the plate from the second sprocket toward the first sprocket and in the process of moving from the first sprocket toward the second sprocket. Can be carried on a plate. Therefore, compared to the case where the conveyor belt is installed in two stages, the drying can be performed more efficiently in a small installation space.

In addition, the same surface of the plate always faces upward to form a transport surface. For this reason, the first shaft for connecting the plate to the endless chain and the second shaft for supporting the guide roller on the plate are opposite to the surface that forms the conveying surface of the plate, that is, the surface that does not contact the object to be dried. On the side, it is possible to fasten to the plate.

However, unlike the case where the object to be dried is conveyed by a continuous element such as a conveyor belt, when the object to be dried is conveyed by forming a conveying surface with a plurality of separated plates, it is between adjacent plates. The transported object may get in. If it does so, the to-be-dried object which entered between plates may become resistance, and there exists a possibility that rotation of the plate around a 1st axis | shaft may be prevented. In particular, an object to be dried conveyed to a plate moving toward the first sprocket has a high degree of adhesion because it has a low degree of drying and still contains a large amount of moisture. Therefore, there is a high possibility that the rotation of the plate around the first axis is hindered in the vicinity of the first sprocket.

In response to such concerns, the transport drying apparatus of the present invention includes a knocker that applies an impact to the plate that is prevented from rotating around the first axis in the vicinity of the first sprocket and rotates the plate. Specifically, the knocker protrudes from a driven gear located above the endless chain between the first sprocket and the end of the upper rail. The driven gear rotates with the rotation of the first sprocket by meshing with the endless chain. The rotation trajectory of the knocker that rotates integrally with the driven gear is in a state in which the rotation around the first axis is prevented when the guide roller moves away from the end of the upper rail due to the movement of the plate toward the first sprocket. It is set to intersect with the plate trajectory when moving forward. Thereby, when rotation around the first axis of the plate is hindered, the knocker collides with the plate moving forward toward the first sprocket from above in the state. This impact can force the plate to rotate about the first axis. In addition, since the driven gear on which the knocker protrudes rotates in mesh with the endless chain, the driven gear can be rotated by a mechanism that drives the rotation of the endless chain, and additional power for rotating the knocker Has the advantage of not requiring.

The conveying type drying apparatus according to the present invention may be "a plurality of conveying apparatuses stacked one above the other" in addition to the above-described configuration.

With this configuration, the material to be dried that has been dried by the upper transport device falls from the plate that rotates around the first axis in the vicinity of the second sprocket, and moves to the plate that moves toward the first sprocket in the lower transport device. Placed and further dried. By laminating a plurality of conveying devices up and down, the distance to be dried can be increased without increasing the area of the installation surface of the device. Thereby, the degree of drying of to-be-dried material can be raised. Moreover, it becomes possible to dry a to-be-dried material with a high moisture content.

In addition to the above-described configuration, the transport-type drying apparatus according to the present invention may be “a plurality of small holes are formed through each of the plates”.

With this configuration, the air circulated in the space in the transport device by the ventilation device passes through the plate on which the material to be dried is placed through the small hole portion. As a result, the material to be dried can be dried more efficiently. As described above, unlike a conveyor belt that requires flexibility, the plate can be formed of a highly rigid material such as metal or resin. Therefore, a large number of small holes can be formed without worrying about a decrease in mechanical strength.

As described above, as an effect of the present invention, it is possible to provide a transport type drying apparatus having a small space for installation and high drying efficiency.

It is a schematic block diagram of the conveyance type drying apparatus which is one Embodiment of this invention. It is one whole figure of the conveying apparatus in the conveyance type drying apparatus of FIG. It is a principal part perspective view of the conveying apparatus of FIG. FIG. 4 is an enlarged view of a range A in FIG. 3. FIG. 3 is a perspective view of a driven gear and a knocker in the transport device of FIG. 2. It is explanatory drawing of operation | movement of the knocker in the conveying apparatus of FIG.

Hereinafter, a conveyance type drying apparatus 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6. Here, the case where this invention is applied to the conveyance-type drying apparatus 1 which dries the chicken excrement discharged | emitted in large quantities from the poultry house 99 every day is illustrated.

The transport-type drying device 1 of this embodiment is a transport-type drying device including a transport device 1a that transports chicken dung containing moisture, and a ventilating device that circulates air through the space inside the transport device 1a. Moreover, in the conveyance type drying apparatus 1 of this embodiment, the conveyance apparatus 1a of the same structure is laminated | stacked up and down two steps, as shown in FIG. The transport drying apparatus 1 is arranged adjacent to a poultry house 99 that raises a large number of birds in a multistage cage, and when the air heated by the body temperature of the birds is exhausted from the poultry house 99 by the exhaust fan 1b. At the same time, it is supplied to the space in the transport device 1a. Here, the exhaust fan 1b corresponds to the ventilation device of the present invention.

Each conveying device 1a includes a pair of endless chains 20, a pair of first sprockets 11 around which one end of each of the pair of endless chains 20 is wound and the endless chain 20 is rotated from top to bottom, and a pair of first sprockets 11 between the pair of endless chains 20 and a pair of second sprockets 12 that are horizontally spaced apart from each other, the other end of each of the pair of endless chains 20 being wound around and rotating the endless chain 20 upward from below. A plurality of endless chains 20 are attached to both endless chains 20 so as to be rotatable around a first axis 21 parallel to the width direction, and each of the plurality of endless chains 20 forms a transport surface on which an object to be dried is placed. The plate 30 and both side surfaces 32 of each of the plurality of plates 30 are rotatably supported around a second shaft 42 that is separated from the first shaft 21. The plate 30 moves from the second sprocket 12 toward the first sprocket 11 by the rotation of the pair of endless chains 20 extending horizontally between the pair of guide rollers 40 and the first sprocket 11 and the second sprocket 12. When the pair of guide rollers 40 is guided, the pair of upper rails 51 that hold the plate 30 horizontally and the first sprocket 11 and the second sprocket 12 extend in the horizontal direction. When the plate 30 moves from the first sprocket 11 toward the second sprocket 12 by the rotation of the endless chain 20, a pair of lower rails guide the rolling of each of the pair of guide rollers 40 and hold the plate 30 horizontally. 52, between the first sprocket 11 and the end of the upper rail 51, above the endless chain 20. A driven gear 60 that is positioned and meshes with the endless chain 20 and rotates as the endless chain 20 rotates, and a knocker 65 that protrudes from the driven gear 60 and rotates with the driven gear 60. When moving toward the first sprocket 11, the first shaft 21 is in front of the second shaft 42, and when the guide roller 40 is removed from the end of the upper rail 51, the plate 30 is moved to the first shaft 21. As the endless chain 20 rotates, the guide roller 40 is guided to the lower rail 52, so that the plate 30 rotates upward around the first shaft 21, and the plate 30 rotates to the second sprocket. When moving toward 12, the first shaft 21 is located behind the second shaft 42, and the plate 30 is moved when the guide roller 40 is disengaged from the end of the lower rail 52. Is rotated downward around the first shaft 21, and the guide roller 40 is guided to the upper rail 51 as the endless chain 20 rotates, so that the plate 30 rotates upward around the first shaft 21. Yes, the rotation trajectory of the knocker 65 moves in a state in which the rotation around the first shaft 21 is prevented when the guide roller 40 is detached from the end of the upper rail 51 by the movement of the plate 30 toward the first sprocket 11. It is set so as to intersect the trajectory of the plate 30 in the case of.

More specifically, the casing of the transport apparatus 1a has two pairs of side walls, and the first sprocket 11 and the second sprocket 12 are respectively at the same height on the pair of opposing side walls 90. It is pivotally supported in a state separated horizontally. That is, one transport device 1 a includes two pairs of sprocket pairs each including the first sprocket 11 and the second sprocket 12. The first sprocket 11 and the second sprocket 12 have the same diameter and the same tooth pitch. When an endless chain 20 is wound around each pair of sprockets and one of the first sprocket 11 and the second sprocket 12 is rotated by a driving device (not shown), the pair of endless chains 20 circulate at the same speed in the same direction.

The endless chain 20 is formed by connecting a large number of link pairs composed of two parallel link plates 22 by connecting pins 23 so as to be rotatable. The connecting pin 23 passes through the free roller 25 between the two link plates 22, and the free roller 25 freely rotates around the connecting pin 23. In each of the pair of endless chains 20, the connecting pins 23 extend beyond the inner link plate 22 at regular intervals. The plurality of plates 30 are rotatably connected from both sides by connecting pins 23 extending inward from each of the endless chains 20 while being positioned between the pair of endless chains 20. Therefore, the axial center of the connecting pin 23 that connects the plates 30 at regular intervals among the connecting pins 23 corresponds to the first shaft 21 of the present invention.

Each plate 30 is a rectangular flat plate in which a large number of small holes (not shown) are formed, and a side surface of the plate body 31 that extends perpendicularly in one direction from a pair of sides in the width direction. Part 32. The above-described connecting pin 23 having the first shaft 21 as an axis is fastened after the side surface portion 32 is inserted. A guide roller 40 is rotatably attached to the side surface portion 32 of the plate 30 by a second shaft 42 at a position away from the first shaft 21. Both the guide roller 40 attached to the plate 30 and the free roller 25 incorporated in the endless chain 20 roll on the rail.

The rail includes a pair of upper rails 51 that guide the rolling of the guide roller 40 and the free roller 25 when the plate 30 moves from the second sprocket 12 toward the first sprocket 11, and the first sprocket 11 to the second sprocket 11. There is a pair of lower rails 52 that guide the rolling of the guide roller 40 and the free roller 25 as the plate 30 moves toward the two sprockets 12. The upper rail 51 and the lower rail 52 are attached to a pair of side walls 90 of the casing so as to extend in the horizontal direction between the first sprocket 11 and the second sprocket 12, respectively. The height of the upper rail 51 is set slightly lower than the upper ends of the first sprocket 11 and the second sprocket 12, and the height of the lower rail 52 is set slightly lower than the lower ends of the first sprocket 11 and the second sprocket 12. In addition, a guide surface 53 that is slightly spaced from the first sprocket 11 and curved in an arc shape along the outer periphery of the first sprocket 11 is provided outside the first sprocket 11 in the radial direction. The lower end of the guide surface 53 reaches the lower rail 52. The guide surface 53 is set so that the diameter of the arc is slightly larger than the diameter of the first sprocket 11 and the center of the arc is located on the extension line of the rotation axis of the first sprocket 11. Further, an arcuate guide surface 54 is provided inwardly in the axial direction of the second sprocket 12 so as to be slightly separated from the second sprocket 12. The guide surface 54 is set so that the diameter of the arc is slightly smaller than the diameter of the second sprocket 12 and the center of the arc is located on the extension line of the rotation axis of the second sprocket 12. The upper end of the guide surface 54 reaches the inner part of the upper rail 51 where the guide roller 40 rolls.

Further, there is a gap that is longer than the length in the traveling direction of one plate 30 between one end of the upper rail 51 and the first sprocket 11 and between one end of the lower rail 52 and the second sprocket 12. Is provided.

There is a pair of driven gears 60, which are pivotally supported by a rotating shaft 61 so as to face a pair of side walls 90 of the casing. The driven gear 60 is located between the end of the upper rail 51 and the first sprocket 11. Since the tooth pitch of the driven gear 60 is set to be equal to the tooth pitch of the first sprocket 11 and the second sprocket 12, the driven gear 60 meshes with the endless chain 20. The height of the driven gear 60 is set to a height that engages with the endless chain 20 moving toward the first sprocket 11 from above.

Rotating bodies 62 that rotate integrally around the rotation shaft 61 of the driven gear 60 are attached to each driven gear 60. The rotating body 62 has three arms 63 extending outward at equal angular intervals (120 degree intervals) with respect to the rotating shaft 61, and each arm 63 has a tip toward the other driven gear 60. A projecting knocker 65 is attached.

In the space between the pair of first sprockets 11, a stopper 59 is supported by a support bar (not shown) attached to the side wall 90 of the casing. The stopper 59 is located directly below the first shaft 21 and at a position where it does not interfere with the first sprocket 11 when the guide roller 40 of the plate 30 moving toward the first sprocket 11 is disengaged from the end of the upper rail 51. It is supported.

With the above configuration, the transport surface is formed by the plurality of plates 30 in the transport device 1a of the transport-type drying device 1 of the present embodiment. Specifically, since each of the plurality of plates 30 is connected to the endless chain 20 by the first shaft 21, it moves with the movement of the endless chain 20 that circulates between the first sprocket 11 and the second sprocket 12. . The first sprocket 11 and the second sprocket 12 are horizontally separated. The first sprocket 11 rotates the endless chain 20 from the top to the bottom, and the second sprocket 12 rotates the endless chain 20 from the top to the bottom. Therefore, the portion of the endless chain 20 that travels from the second sprocket 12 to the first sprocket 11 moves on the portion that travels from the first sprocket 11 to the second sprocket 12. Therefore, hereinafter, the movement from the second sprocket 12 toward the first sprocket 11 is referred to as “upward movement”, and the movement from the first sprocket 11 toward the second sprocket 12 is referred to as “downward movement”.

The guide roller 40 rotatably attached to the both side surfaces 32 of each plate 30 around the second shaft 42 rolls on the upper rail 51 as the plate 30 moves upward, and moves downward on the plate 30. As a result, it rolls on the lower rail 52. The height of the upper rail 51 and the lower rail 52 is related to the height of the first shaft 21 connected to the endless chain 20, and the plate 30 is horizontal while the guide roller 40 rolls on the rail. Is set as follows. In the present embodiment, the free roller 25 of the endless chain 20 also rolls on the upper rail 51 and the lower rail 52. The free roller 25 and the guide roller 40 have substantially the same diameter, and the first shaft 21 that is the rotation shaft of the free roller 25 and the height of the side surface 32 of the second shaft 42 that is the rotation shaft of the guide roller 40 are set to be the same. Has been. As a result, the plate 30 becomes horizontal while the free roller 25 and the guide roller 40 roll on the upper rail 51 or the lower rail 52.

Further, when the plate 30 moves upward, the first shaft 21 connecting the plate 30 to the endless chain 20 is in front of the second shaft 42 that is the rotation shaft of the guide roller 40. As a result, the plate 30 is pulled by the endless chain 20 during the upward movement, and the guide roller 40 rolls on the upper rail 51 accordingly. The plurality of plates 30 on which the guide roller 40 rolls on the upper rail 51 are in a horizontal state, whereby a transport surface is formed by the upper surface of each plate 30. Accordingly, the material to be dried can be placed on the transport surface by supplying the material to be dried onto the plate 30 moving upward by the supply device 91 such as a conveyor belt or a hopper.

As described above, a gap longer than the length in the traveling direction of the plate 30 is provided between the first sprocket 11 and the end of the upper rail 51. As a result, when the plate 30 moving upward approaches the first sprocket 11 and the guide roller 40 is disengaged from the end of the upper rail 51, the plate 30 rotates downward around the first shaft 21 by its own weight. To do. In the upward movement, since the first shaft 21 is in front of the second shaft 42, the plate 30 rotates so that the upper surface that has previously formed the transport surface faces the direction of the second sprocket 12. By the rotation of the plate 30, the object to be dried that has been placed so far falls. In the present embodiment, when the plate 30 rotates, the plate 30 collides with a stopper 59 located directly below the first shaft 21. Thereby, the further rotation is restricted, and the object to be dried attached to the plate 30 can be wiped off by the impact of the collision.

The plate 30 supported by the endless chain 20 so as to be suspended from the first shaft 21 moves downward together with the endless chain 20 that meshes with the first sprocket 11 and rotates from top to bottom. At that time, the guide roller 40 is guided by the guide surface 53 that is curved along the outer periphery of the first sprocket 11, and the plate 30 gradually rotates upward around the first shaft 21. When the guide roller 40 comes into contact with the lower rail 52 from above and the plate 30 moves toward the second sprocket 12 while rolling the guide roller 40 on the lower rail 52, the plate 30 becomes horizontal again and moves upward. The same surface as the surface on which the transport surface is formed faces upward to form the transport surface. The plate 30 that has become horizontal in this manner places an object to be dried dropped from the plate 30 rotated around the first axis 21 on the transport surface and transports it while moving downward. At this time, since the first shaft 21 is behind the second shaft 42, the endless chain 20 is moved downward so as to push the plate 30.

When the plate 30 moving downward approaches the second sprocket 12 and the guide roller 40 is detached from the end of the lower rail 52, the plate 30 rotates around the first shaft 21 by its own weight. Since the first shaft 21 is behind the second shaft 42, the plate 30 rotates so that the surface that has previously formed the transport surface faces the direction of the second sprocket 12. By the rotation of the plate 30, the object to be dried that has been placed so far falls. The plate 30 supported by the endless chain 20 so as to be suspended from the first shaft 21 moves upward together with the endless chain 20 that meshes with the second sprocket 12 and rotates from the bottom to the top. At this time, the guide roller 40 is guided by an arcuate guide surface 54 located slightly inside the second sprocket 12, and the plate 30 gradually rotates upward around the first shaft 21. When the guide roller 40 reaches the upper rail 51 and the plate 30 moves toward the first sprocket 11 while rolling the guide roller 40 on the upper rail 51, the plate 30 becomes horizontal again. The plate 30 is moved upward by placing the material to be dried supplied from above, and then the above operation is repeated.

As described above, the plurality of plates 30 repeat the upward movement and the downward movement as the endless chain 20 circulates, so that the object to be dried conveyed by the conveyance surface formed by the upwardly moving plate 30 is moved downward. It is dropped and conveyed on the conveyance surface formed by 30. In the present embodiment, since the two conveying devices 1a are stacked one above the other, the object to be dried that has dropped from the plate 30 that has finished moving downward in the upper conveying device 1a moves upward in the lower conveying device 1a. 30. Thereafter, the sheet is transported by the plate 30 moving upward in the lower transport apparatus 1a, and further dropped and transported onto the plate 30 moving downward. The object to be dried is dried by the warm air sent into the space in the transfer device 1a by the exhaust fan 1b in the process of being transferred by the plate 30 moving upward and downward in each transfer device 1a. In particular, in the present embodiment, since a large number of small holes are formed in the plate main body 31, as shown by broken line arrows in FIG. 1, the plate 30 and the object to be dried placed on the plate 30 pass therethrough. Air circulates like Thereby, a to-be-dried object can be dried efficiently.

In addition, the dried to-be-dried object that has dropped from the plate 30 that has been moved downward in the lower conveyance device 1a is carried out of the conveyance drying device 1 by a carry-out device 92 such as a screw conveyor or a scraper.

Unlike the conveyor belt that conveys the object to be dried on a continuous surface, the conveyance device 1a of the present embodiment forms the conveyance surface with a plurality of separated plates 30 and conveys the object to be dried. Therefore, there is a possibility that the object to be conveyed enters between the adjacent plates 30 and the rotation of the plate 30 around the first shaft 21 is hindered. In particular, an object to be dried at the stage of being conveyed by the plate 30 moving upward is likely to adhere between the plates 30 because the moisture content is still high.

In such a case, the plate 30 that should rotate around the first axis 21 in the gap between the end of the upper rail 51 and the first sprocket 11 is in a substantially horizontal state as shown in the upper diagram of FIG. It moves toward the first sprocket 11 while maintaining. At this position, a driven gear 60 is attached so as to mesh with the endless chain 20 from above, and a knocker 65 projects from a rotating body 62 that rotates integrally with the driven gear 60. Therefore, when the driven gear 60 that meshes with the endless chain 20 rotates in the opposite direction as the first sprocket 11 rotates, the knocker 65 also rotates. The rotation trajectory of the knocker 65 is set so as to intersect with the trajectory of the plate 30 moving forward in a state where the rotation around the first axis 21 is prevented. Therefore, as shown in the lower diagram of FIG. 6, the rotating knocker 65 collides with the moving plate 30 without rotating around the first axis 21.

This impact can weaken the adhesive force between the plate 30 and the object to be dried and rotate the plate 30 around the first shaft 21. In particular, in the present embodiment, as illustrated, the position of the knocker 65 is set such that the position where the knocker 65 collides with the plate 30 is a position away from the first shaft 21. Therefore, even if the force applied from the knocker 65 is the same, it is easier to rotate the plate 30 around the first axis 21 than when the knocker 65 collides at a position close to the first axis 21. In the present embodiment, the knocker 65 protruding from each of the pair of driven gears 60 collides with both sides of the plate 30 at the same time. Therefore, the force from the knocker 65 is easily transmitted to the entire plate 30, and the plate 30 can be rotated more reliably.

Further, since the driven gear 60 on which the knocker 65 is protruded can be rotated by a mechanism that drives the rotation of the endless chain 20, the knocker 65 can be rotated without requiring additional power.

Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited to the above-described embodiments, and various improvements and design changes can be made without departing from the scope of the present invention. It is.

For example, in the above-described embodiment, the case where a plurality of transfer apparatuses 1a having the same configuration are stacked vertically is illustrated. However, the present invention is not limited to this, and only the uppermost transport device having a low degree of drying of the object to be dried can be configured to include a knocker. This is because an object to be dried that has been dried is difficult to adhere to the plate. In this case, the other conveying device on the lower side can be configured by removing the driven gear 60, the rotating body 62, and the knocker 65 from the conveying device 1a.
