Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a transfer device for smoothly transferring a transferred object between a main body and a relay means provided between subsequent steps.

As this kind of thing, the conveyance device indicated in patent documents 1 is known.
As shown in FIG. 6, the transport apparatus includes a main body 1 as a transport means and a plate member 2 as a relay means for relaying to another process.

In the main body 1, the net conveyor belt 4 is stretched around a pair of transmission rotary bodies 3, and the transmission rotary body 3 is rotated to convey the conveyed object S placed on the net conveyor belt 4 in the conveyance direction 5 It is a thing.
Further, the plate member 2 is provided on the downstream side of the transport direction 5 of the main body 1 in order to relay the transported object S to another process. The plate member 2 is provided at substantially the same height as the conveying surface 4 a of the net conveyor belt 4.
A predetermined gap 6 is provided between the main body 1 and the plate member 2 so as not to prevent the movement of the net conveyor belt 4.

In the above conveying apparatus, the head pressing device 7 synchronized with the traveling speed of the main body 1 in order to feed the next step while keeping the conveyed object S upright is at the downstream side of the conveying direction 5 of the main body 1 It is provided at the top.
The head pressing device 7 is configured by stretching an endless belt 7c around a pair of rotating bodies 7a and 7b connected to a power source (not shown). Such a head pressing device 7 causes the endless belt 7 c to travel while pressing the head of the conveyed conveyed product S.

The downstream end of the head pressing device 7 is disposed in front of the plate member 2 so that the conveyed product S is separated from the head pressing device 7 in front of the plate member 2.
If the head retainer 7 jumps forward in the transport direction 5 even by a little more than the plate member 2, only the head of the conveyed object S that has passed the main body 1 is pressed by the head retainer 7. As a result, the conveyed product S falls to the front.

Since it is almost impossible to completely match the end of the main body 1 and the end of the head pressing device 7 which separates the conveyed product S, considering the dimensional error of the parts, the assembly error, etc. The end of the pressing device 7 is located rearward of the end of the main body 1 in the transport direction 5.
Then, the conveyed product S separated from the head pressing device 7 is pushed out by the subsequent conveyed product S and sent to the plate member 2 as the relay means.

On the other hand, the above-described transfer device is also used for the water removal device and the dust removal device. For example, the water removal apparatus sprays compressed air in the process of transporting the washed product S and blows off water droplets.
In such a water removal apparatus, in order to blow compressed air on the whole surface of the conveyed product S in the conveyance process, air nozzles are provided above, beside, and below the conveyance path.

In order to provide an air nozzle below the net conveyor belt 4, the net removal belt having a coarse mesh is used in the water removal apparatus, and compressed air from the air nozzle provided below is on the bottom side of the conveyed product S. It is made to blow evenly.
FIG. 7 shows this coarse net conveyor belt 4.

The net conveyor belt 4 shown in FIG. 7 has a high tension to a certain extent, and is of a type with little net elongation, so that it can withstand the weight of the conveyed product S and the wind pressure of compressed air. The configuration is as follows.
The net conveyor belt 4 arranges a plurality of wire rods 9 bent in a flat spiral shape in the transport direction 5 and pierces the connecting rods 8 in the folded back portions 9a of the adjacent wire rods 9, Each wire rod 9 is connected. Then, both ends of the connecting rod 8 are fixed to a roller chain (not shown).

  The net conveyor belt 4 as described above has a level difference between the front and back sides of the folded back portion 9a and between the connecting rod 8 and the folded back portion 9a. However, since the mesh can be roughened, the function of uniformly blowing compressed air from the air nozzle provided below the net conveyor belt 4 to the bottom side of the conveyed product S is prioritized.

JP, 2004-323210, A JP 10-250816 A

In the conventional conveyance device, since the conveyed product S is separated from the head holding device 7 in front of the plate member 2 which is the relay means, even if a slight impact is applied to the conveyed material S after separated from the head holding device 7 There was a problem that it fell.
In particular, when the net conveyor belt 4 is used, there is a case in which the conveyed product S tends to fall when it transfers from the main body 1 to the plate member 2.

  For example, when the net conveyor belt 4 approaches the curved surface of the transmission rotary body 3, the folded portion 9a of the wire rod 8 protrudes upward, and a step is generated on the transport surface 4a. In particular, although the net conveyor belt 4 in the water removal apparatus or the like has to accept the instability of the conveyed product S placed thereon to a certain extent, in the vicinity of the transmission rotating body 3 as described above, the influence of the step is The instability is even more pronounced.

Under such circumstances, if the conveyed product S leaves the head holding device 7 in front of the plate member 2, the conveyed product S will be placed in an increasingly unstable state, Even a slight vibration etc. will fall over.
If the conveyed product S falls in the conveyance process, the subsequent conveyed product S falls in succession, which may lead to a major problem of having to stop the production line in some cases.
In any case, there is a problem that the conventional transfer device can not be used for the water removal device that must use the net conveyor belt 4 and the application is limited.

In addition, when the net conveyor belt 4 travels along the transmission rotating body 3, the folded back portion 9a draws a maximum rotation locus. Therefore, although the plate member 2 as the relay means has to be separated from the maximum rotation locus, a large gap 6 is formed between the plate member 2 and the main body 1 accordingly.
If the conveyed product S is separated from the head holding device 7 in front of the plate member 2, the conveyed product S falls into a large gap 6 or stumbles upon it.

Also for this reason, there is a problem that the application is limited so that the conventional transfer device can not be used for the water removal device or the dust removal device using the net conveyor belt 4.
In addition, since the head restraint device 7 must be synchronized with the traveling speed of the main body 1, the entire device becomes complicated, which causes a problem of cost increase.
In addition, although the said conveying apparatus is used also for the dust removal apparatus which blows off compressed air and blows away refuse, the net conveyor belt 4 is used also with this dust removal apparatus. Therefore, the dust removal apparatus also has the same problem as the water removal apparatus.

  An object of the present invention is to provide a conveying device which prevents the above-mentioned conveyed product from falling even when a net conveyer belt having a coarse mesh like a water removing device or a dust removing device is used.

  According to a first aspect of the present invention, there is provided a main body for carrying an endless carrier band around a pair of transmission rotating bodies and for conveying a cylindrical article, and relay means provided between the main body and the next step. On the assumption that the And while an inclination suppression means is provided above one transmission rotary body in the conveyance direction downstream side of the said main body, this inclination suppression means is kept stationary in a conveyance direction, and is provided in non-drive. Further, the tilt suppressing means tilts the load until the leading end of the load in the transfer direction of the load exceeds at least the beginning of the relay by exceeding the interval formed between the main body and the relay. I try to suppress.

  In order to suppress the inclination, the inclination suppressing means may be kept in contact with the upper portion of the conveyed product, or when the conveyed object is inclined to some extent, the inclination suppressing unit is the first upper portion of the conveyed product. It may be in contact with the

Further, in the present invention, the cylindrical conveyance includes a cylindrical container such as a can, a conical container such as a bottle and a plastic bottle, and a rectangular cylindrical container. And a cylindrical conveyance thing includes not only a thing with a high center of gravity like a can or a bottle but a conveyance thing with a low center of gravity, such as a container of a jelly, is included.
And, as the relay means, a member such as a roller or a fixed rod or plate can be used. Furthermore, as the relay means, one using a power mechanism may be used.

  According to a second aspect of the present invention, the inclination suppressing means comprises a plurality of rollers, and the rollers are aligned in the conveyance direction of the main body, and the axes of the rollers are provided orthogonal to the conveyance direction.

According to a third aspect of the present invention, the relay means comprises a roller conveyor provided with a plurality of rollers. The rollers are aligned in the transport direction of the main body, and the axes of the rollers are provided to be orthogonal to the transport direction. And, the roller conveyor is installed so as to continue obliquely downward toward the next process.
Further, the inclination suppressing means is configured to suppress the inclination of the conveyed product until the leading end of the conveyed product in the conveyance direction reaches the plurality of rollers.

According to the first aspect of the invention, since the inclination suppressing means suppresses the inclination of the conveyed product until the leading end of the conveyed product in the conveyance direction reaches at least the beginning of the relaying means beyond the interval, for example, Even when the net conveyor belt is used as the endless transport belt, the transported object does not fall over when it transfers from the main body to the relay means.
As described above, since the conveyed product is not to be overturned in the conveyance process, a large problem such as falling of the conveyed product and stopping the production line can be avoided.

In addition, even if a large gap is formed between the net conveyor belt and the relay means by using the net conveyor belt in the endless conveyor band, the sheet is conveyed by the inclination suppressing means until the conveyed object exceeds the space. Since the inclination of the object is suppressed, the conveyed object does not fall into a large interval or trip over it and fall down.
Furthermore, since the inclination suppressing means does not have to synchronize the traveling speed with the main body as in the prior art, the entire device is simplified. In addition, since the tilt suppression means does not require power, the cost can be greatly reduced.

According to the second aspect of the invention, since the rotatable roller is used as the inclination suppressing means, even if the conveyed product and the roller come in contact with each other, the contact portion moves smoothly in the conveying direction. Since the contact portion moves smoothly in this manner, the moving speed of the head of the transported object does not become slower than the transporting speed of the main body. If the contact portion does not move smoothly and the moving speed of the head of the conveyed object becomes slower than the conveying speed of the main body, the conveyed object falls on the back.
However, in the second aspect of the invention, since the rotatable roller is used as the inclination suppressing means, the transported object does not fall over.

  According to the third aspect of the invention, the inclination suppressing means suppresses the inclination of the conveyed product until the leading end of the conveyed product in the conveyance direction reaches the plurality of rollers, so that the roller and the roller are rotated. There is no possibility of falling over due to the product being tripped.

It is the perspective view which showed only the structure which concerns on an inclination suppression means. It is the enlarged bottom view which looked at the composition concerning the inclination control means from the bottom. It is the expansion side view which saw the apparatus which attached the inclination suppression means from the downstream of the conveyance direction. It is the schematic which showed the conventional conveying apparatus. It is the enlarged plan view which showed the net conveyor belt used with the conventional conveying apparatus.

  FIGS. 1-5 shows embodiment which mounted the conveying apparatus of this invention in the water removal apparatus. Such a water removal apparatus is often installed later between machines of the plant, and it is required to smoothly deliver the conveyed product S to the next process.

  In this embodiment, as shown in FIG. 1, the main body 1 of the transfer device of the present invention is mounted on the base 10 of the water removing device, and the main body 1 is completely the same as the conventional net shown in FIG. A conveyor belt 4 is used. That is, the net conveyor belt 4 which is the endless conveyance band of the present invention is passed over a pair of transmission rotary bodies 3 and 3 ', and the transmission rotary bodies 3 and 3' are rotated by a power source not shown. The transported object S placed on the transport surface 4 a of the above is transported in the transport direction 5.

Then, in the net conveyor belt 4 as well, when the folded portion 9a of the wire rod 8 protrudes upwards along the curved surface of the transmission rotary body 3, a step is produced on the transport surface 4a or the vicinity of the transmission rotary body 3. However, there is also a problem that the instability becomes even more pronounced due to the influence of the step.
The configuration of the net conveyor belt 4 is the same as the conventional configuration, and thus the detailed description thereof is omitted.

As shown in FIG. 2, the main body 1 of the transfer device is mounted on the base 10 of the water removal device as described above, and the base 10 is located below the transfer surface 4 a of the net conveyor belt 4. A first injection unit 11 is provided, and a second injection unit 12 is provided at a position facing the first injection unit 11.
The first injection unit 11 is provided with a plurality of lower nozzles (not shown), and these lower nozzles blow compressed air toward the bottom surface of the conveyed product S.

Further, a second injection unit 12 which can be opened and closed with respect to the base 10 is provided on the base 10 at a position facing the first injection unit 11.
When the second injection unit 12 is closed to the base 10, the transport surface 4a of the main body 1 and the ceiling surface 13 of the second injection unit 12 face each other. The ceiling surface 13 is provided with a plurality of upper nozzles 14 that jet compressed air downward from above the base 10.
The lower nozzle provided in the first injection unit 11 and the upper nozzle 14 provided in the second injection unit 12 face each other at the top and bottom, and the facing interval between the first injection unit 11 and the second injection unit 12 , And the processing area D to which the water removal processing is to be performed.

Further, the ceiling surface 13 of the second injection unit 12 is provided with a lateral nozzle 15 different from the upper nozzle 14.
The lateral direction nozzle 15 is attached so as to sandwich the transported object S passing through the processing area D.

  The first injection unit 11 and the second injection unit 12 use a direct nozzle that directs the opening to the article S and a swirling nozzle that automatically rotates the opening when compressed air is supplied. There is. These direct nozzles and the swirl nozzle can be freely combined according to the purpose of water removal treatment.

Furthermore, after the transported product S transported by the main body 1 of the transport apparatus is dewatered in the processing area D, it is transported to the guiding area G which is continuous downstream of the processing area D.
The guidance area G is an area provided on the downstream side of the net conveyor belt 4 and between the processing area D and the roller conveyor 16 which is a relay means of the present invention described later.

At the downstream end of the guiding area G, a roller conveyer 16 is provided which is composed of a plurality of rollers as relay means for transferring the conveyed product S to the next process. As shown in FIG. 1, the roller conveyor 16 is continuous with the conveying direction 5 of the net conveyor belt 4 and inclined downward toward the next step.
Since the roller conveyor 16 is inclined obliquely downward toward the next process, when the conveyed product S rides on the roller conveyor 16, the conveyed product S is automatically delivered to the next process by its own weight. .

And, in this embodiment, since the net belt conveyor 4 is used, the roller conveyor 16 must be set apart from the maximum rotation locus. As a result, a large space 6 is created between the roller conveyor 16 and the net conveyor belt 4.
Thus, since the large space 6 is formed, the conveyed product S transported by the net conveyor belt 4 falls into the large space 6 or stumbles upon it. However, in this embodiment, since the inclination suppressing means R described below is provided, the conveyed object S can be smoothly conveyed without being fallen.

As shown in FIG. 1, on the downstream side of the conveyance direction 5 in the main body 1 of the conveyance apparatus, an inclination suppression means R for suppressing the inclination of the conveyance object S is provided above one transmission rotary body 3 .
The inclination suppressing means R includes a plurality of rollers 17 provided to the holding member 18 as shown in FIG. The holding member 18 is provided with facing pieces 18a, 18a provided on both sides of the ceiling plate 18b, and the plurality of rollers 17 are rotatably spread between the facing pieces 18a, 18a.
The inclination suppressing means R as described above is provided above the one transmission rotary member 3 on the downstream side in the transport direction 5 of the main body 1 as described above. The configuration of the support mechanism H supporting the inclination suppressing means R Is as follows.

A pair of support pieces 19a, 19a are fixed and erected on the base 10 of the water removal apparatus, on the side of the transport surface 4a of the net belt conveyor 4, and the support pieces 19a, 19a are made parallel. They are facing each other.
The upper ends of the support pieces 19a, 19a are provided with bent pieces 19b, 19b bent in the opposite direction.

Between the bent pieces 19b, 19b, a channel-like longitudinal adjustment member 20 provided with raised portions 20b, 20b on both sides of the flat portion 20a is hung so as to straddle the conveying direction 5 of the net conveyor belt 4. It has been passed.
Further, in the longitudinal adjustment member 20, as shown in FIG. 4, elongated holes 21 for adjusting the position in the longitudinal direction are formed in the flat portion 20a, and these elongated holes 21 and 21 are penetrated. The front and rear direction adjusting member 20 is fixed to the bending pieces 19 b and 19 b via the bolts 22 and 22. Moreover, the long holes 21 and 21 have their major axis directions substantially parallel to the transport direction 5.
Therefore, the longitudinal position of the longitudinal adjustment member 20 with respect to the conveying direction 5 can be adjusted by loosening the bolts 22 and moving the longitudinal adjustment member 20 back and forth along the long holes 21.

Further, vertical adjustment plates 23, 23 are attached to the outer side surfaces of the respective rising portions 20b, 20b of the longitudinal adjustment member 20 as described above. As shown in FIG. 5, a pair of elongated holes 24 for adjusting the position in the vertical direction are formed in each of the vertical direction adjusting plates 23 and 23, and bolts passing through the elongated holes 24 and 24 are formed. The vertical adjustment plates 23, 23 are fixed to the rising portions 20b, 20b via the members 25, 25, respectively. Moreover, the long holes 24, 24 have their long axis direction directed in the vertical direction substantially orthogonal to the conveying direction 5.
Therefore, the vertical position of the vertical adjustment plates 23, 23 can be adjusted by loosening the bolts 25, 25 and vertically moving the vertical adjustment plates 23, 23 along the rising portions 20b, 20b.

Further, the lower ends of the vertical adjustment plates 23, 23 are fixed to the ceiling plate 18b of the holding member 18 described above.
Therefore, the inclination suppressing means R is attached to the longitudinal adjustment member 20 via the vertical adjustment plates 23, 23. The longitudinal adjustment member 20 is supported by the support piece 19a.
As apparent from this, the support piece 19a, the longitudinal adjustment member 20, and the vertical adjustment plates 23, 23 together form a support mechanism H of the inclination suppressing means R, and can be moved back and forth. The direction adjusting member 20 and the vertical direction adjusting plates 23, 23 together constitute a position adjusting mechanism of the inclination suppressing means R.

As described above, the inclination suppressing means R supported by the support mechanism H has axes of the plurality of rollers 17 perpendicular to the conveying direction 5 above the conveying surface 4 a of the net conveyor belt 4 as shown in FIG. It will be aligned keeping the position of
At this time, the back and forth position and the up and down position of the inclination control means R can be adjusted within the range of the long holes 21 and 21 and the long holes 24 and 24 as described above.

  Since the inclination suppressing means R as described above is fixed to the base 10 of the water removal apparatus by the support mechanism H, the stationary state is maintained in the transport direction 5. Moreover, the inclination control means R has no driving force and is not driven.

And since the said roller 17 is rotatably provided, even if the said conveyed product S and the roller 17 contact, the conveyed product S moves to the conveyance direction 5 smoothly. Since the movement is smooth as described above, the moving speed of the head of the conveyed product S is slower than the conveying speed of the main body 1 and does not fall over.
Furthermore, since the roller 17 does not have to adjust the transport speed in accordance with the transported object S, it is not necessary to provide a drive mechanism.

In this embodiment, a gap is provided between the conveyed product S and the roller 17 in the process of conveying the main body 1. Then, when the conveyed product S is inclined to a certain extent at a portion along the curved surface of the transmission rotating body 3, the conveyed product S is brought into contact with the head of the conveyed product S when the conveyed product S is inclined to some extent. It is provided as.
The inclination suppressing means R provided in this manner is configured to suppress the inclination of the conveyed product S until the leading end s1 of the conveyed product S in the conveying direction exceeds the interval 6 and reaches the roller conveyer 16.
The gap can be adjusted using the position adjusting mechanism according to the height of the conveyed product S.

According to this embodiment, the inclination suppressing means R suppresses the inclination of the conveyed product S while the conveyance direction front end s1 of the conveyed product S exceeds the interval 6 and reaches at least the start end of the roller conveyor 16. For example, even when the net conveyor belt 4 having a coarse mesh is used, the conveyed product S does not fall over when it transfers from the main body 1 to the roller conveyor 16.
As described above, since the conveyed product S does not fall down in the conveyance process, it is possible to avoid a large trouble such as stopping the production line.

  Further, even if a large space 6 is formed between the main body 1 and the roller conveyor 16, the inclination suppressing means R suppresses the inclination of the conveyed product S until the conveyed product S exceeds the space 6. Therefore, the conveyed product S does not fall into the above-mentioned large space 6 or falls by it.

  Further, since the roller 17 constituting the inclination suppressing means R is automatically rotated in accordance with the conveying speed of the conveyed object S in contact with it, no driving force is particularly required. If the inclination suppressing means R has a driving force, the traveling speeds of the inclination suppressing means R and the main body 1 must be mechanically synchronized. When this happens, the entire device becomes complicated, which causes an increase in cost. However, since the inclination suppressing means R of this embodiment is not driven, the cost is significantly reduced.

In addition, although this embodiment is demonstrated using a water removal apparatus, it can use also for the conveyance apparatus used for another use. For example, it can be used in a dust removing apparatus for removing dust attached to the conveyed product S.
Moreover, although the several roller 17 in this embodiment makes the axis line orthogonal to the conveyance direction 5, according to the conveyance direction 5 of the conveyed product S, the direction of the roller 17 can also be changed freely. For example, the conveyed product S may be skewed on the conveying surface 4a of the net conveyor belt 4, but in this case, the roller 17 can also be skewed in accordance with the skew.

  And in this embodiment, although this inclination control means R is constituted using a plurality of rollers 17, for example, it may constitute using plate-like or a rod-like member. The inclination suppressing means R keeps the stationary state in the conveying direction 5 and is not driven, and at least until the leading end s1 of the conveyed object S in the conveying direction reaches the interval 6 and reaches at least the beginning of the relay means. A member of any shape may be used as long as the inclination of the conveyed product S can be suppressed.

  Further, in this embodiment, the roller conveyer 16 serving as the relay means is provided to be continuous obliquely downward toward the next step. However, the upper surface of the roller conveyer 16 is the conveyance surface 4 a of the net conveyor belt 4. It may be provided horizontally with the same height.

In addition, when the inclination angle of the relay means formed by the roller conveyor 16 becomes large, the roller between the rollers constituting the roller conveyor 16 stumbles and tends to fall over.
In such a case, the position adjusting mechanism of the inclination suppressing means R is used so that the inclination of the conveyed object S can be suppressed until the conveyance direction front end s1 of the conveyed object S reaches the plurality of rollers. Front and back position can be adjusted. By adjusting the back and forth position of the inclination suppressing means R, the conveyed product S is delivered to the roller conveyor 16 at a position sufficiently beyond the roller and between the rollers, so the conveyed product S does not trip and fall over. .

  Moreover, in this embodiment, although the rotatable roller conveyor 16 is used for the relay means, a member such as a fixed plate or rod can be used for the relay means. Also, as the relay means, one using a power mechanism may be used.

  The present invention can be applied to the case of transferring a conveyed product to the next step from the main body as the conveying means through the relay means.
