Description

The present invention relates to, for example, a transfer plate device arranged between an upstream conveyor and a downstream conveyor that conveys a container filled with drinking water.

When transporting containers such as bottles and cans over a long distance, a plurality of conveyors are arranged in series in the transport direction so that the containers are delivered from the upstream conveyor to the downstream conveyor. As disclosed in Patent Document 1, a flat plate-shaped transfer plate for transferring a container between conveyors may be provided at a connection portion between an upstream side conveyor and a downstream side conveyor.

Since the transfer plate of Patent Document 1 has a substantially inverted triangular cross-sectional shape and is supported by a support plate made of a spring plate, even if a large number of parallel containers are simultaneously placed on the transfer plate, the transfer plate bends downward. And lateral warpage is prevented. Therefore, a large number of containers conveyed in parallel in the multi-row conveyor can be smoothly transferred from the upstream conveyor to the downstream conveyor without tipping over.

Japanese Unexamined Patent Publication No. 2014-94422

A conveyor provided with a transfer plate may have dimensions as large as 2 m in the width direction as an example. The width direction means a direction orthogonal to the direction in which the container is conveyed. The transfer plate also has a total length similar to the width direction of the conveyor, but it is not easy to secure the dimensional accuracy of the transfer plate over this total length. Normally, it is recommended that the transfer plate be set at the same height as the transport surface of the container on the conveyor or by a small amount below the transport surface, but due to dimensional errors, there may be parts that are actually higher than the transport surface. There is also a low part. If there is a transport surface, that is, a portion where the transfer plate is higher than the reference surface, the container described below may remain.

A beverage production line provided with a transfer plate may be used to fill a large-sized container with a beverage to produce a beverage product, or to fill a small-sized container with a beverage to produce a beverage product. Larger dimensions mean higher height and diameter or width, and smaller dimensions mean smaller height and diameter or width. If the container is cylindrical, the diameter is applied, and if the container is square, the width is applied.

A container having a diameter or width smaller than the size of the transfer plate in the transport direction may ride on a portion higher than the reference surface of the transfer plate and may remain on the transfer plate without being delivered to the conveyor on the downstream side. In particular, the container located at the end of the plurality of containers to be transported tends to remain on the transfer plate. That is, since the container located before the tail end receives the transport force from the conveyor on the downstream side via the subsequent container, it is pushed by the conveyor on the upstream side even if it rides on the transfer plate. On the other hand, if the last container rides on the transfer plate, it cannot receive the carrying force and remains on the transfer plate. In addition, if the position of the transfer plate is high before riding on the vehicle, it may hit the transfer plate and may not pass through the transfer plate.

If the container remaining on the transfer plate is left as it is, when different beverages are produced on the same production line, the containers filled with different beverages may be mixed as foreign substances. Therefore, the workers involved in the production line remove the remaining containers, but this work reduces the production efficiency.

From the above, it is an object of the present invention to provide a transport device provided with a transfer plate through which a container having a small size can pass through without remaining.

The transport device of the present invention includes an upstream side conveyor for transporting articles, a downstream side conveyor for transporting articles, and a transfer plate device provided between the upstream side conveyor and the downstream side conveyor. The transfer plate device in the present invention includes a transfer plate for delivering the article conveyed from the upstream conveyor to the downstream side, and an elevating mechanism for moving the transfer plate up and down.

The elevating mechanism in the present invention preferably repeats the operation of lowering the delivery surface of the transfer plate from the first position to the second position and then raising it from the second position to the first position.
The second position preferably has the delivery surface below the transfer surface of the article identified by the upstream and downstream conveyors.
The article in the present invention can receive the conveying force by the downstream conveyor when the delivery surface is in the second position.

The elevating mechanism in the present invention preferably moves up and down while the upstream conveyor is being driven.
The elevating mechanism in the present invention can repeat the operation for a period of delivering the article to the downstream side, or can repeat the operation only for a part of the period of delivering the article to the downstream side.

The elevating mechanism in the present invention can repeat the operation by the driving force of the upstream conveyor or the downstream conveyor.

It is preferable that the elevating mechanism in the present invention can adjust the elevating amount of the transfer plate.

The present invention includes a transfer plate for delivering an article conveyed from the upstream side to the downstream side, a support for supporting the transfer plate, and an elevating mechanism for raising and lowering the transfer plate via the support. Equipment is also provided.

The elevating mechanism in the present invention preferably repeats the operation of lowering the transfer plate from the first position to the second position and then raising it from the second position to the first position.
Further, the elevating mechanism in the present invention can repeat the operation for a period of delivering the article to the downstream side, or can repeat the operation only for a part of the period of delivering the article to the downstream side.
Further, the elevating mechanism in the present invention can repeat the operation by the drive source for transporting the article.

According to the present invention, it is assumed that the last article rides on the delivery surface of the delivery plate. However, if the transfer plate is lowered, the article on the transfer surface can receive the transfer force from one or both of the upstream conveyor and the downstream conveyor. Therefore, the last article is suppressed from remaining on the transfer plate and is delivered to the downstream conveyor. Therefore, the work of removing the remaining article by the worker can be omitted.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 1, the transport device 1 according to the present embodiment includes a transfer plate 11 that moves up and down in the vertical direction V. Even if the container 100 rides on the transfer plate 11, the container 100 can come into contact with the upstream side conveyor 30 and the downstream side conveyor 40 by lowering the transfer plate 11. As a result, a conveying force is applied to the container 100, and the container 100 can be transferred from the transfer plate 11 to the downstream conveyor 40, so that the container 100 can be prevented from remaining. Hereinafter, the configuration, operation, and effect of the transport device 1 will be described in this order.
In the present embodiment, for example, a container 100 filled with a beverage will be described as an example of the article, but the transport device 1 of the present embodiment does not have a unique configuration with respect to the container 100, and an article other than the container 100. It is clear from the following explanation that it can be widely applied to.

[Components of Conveyor Device 1]
As shown in FIG. 1, the transport device 1 includes an upstream side conveyor 30, a downstream side conveyor 40, and a transfer plate device 10 provided between the upstream side conveyor 30 and the downstream side conveyor 40. The upstream side conveyor 30 and the downstream side conveyor 40 are connected in series in the transport direction L, and a transfer plate device 10 is provided at a connecting portion between the upstream side conveyor 30 and the downstream side conveyor 40.

In this embodiment, as shown in FIG. 1, the upstream U and the downstream D in the transport device 1 are defined by the orientation in which the container 100 is transported. However, the upstream U and the downstream D have relative meanings. For example, the upstream conveyor 30 is provided on the upstream U of the transfer plate device 10, and the downstream conveyor 40 is provided on the downstream D of the transfer plate device 10. ..
Further, the transport direction L, the vertical direction V, and the width direction W are as shown in FIGS. 1 and 2, the transport direction L and the width direction W are orthogonal to each other, and the plane including the transport direction L and the width direction W is the horizontal direction. Make parallel.

[Passing plate device 10]
As shown in FIG. 1, the transfer plate device 10 is provided between the upstream side conveyor 30 and the downstream side conveyor 40, and bridges the container 100 to which the upstream side conveyor 30 has been conveyed to transfer to the downstream side conveyor 40. ..

As shown in FIGS. 1 to 3, the transfer plate device 10 includes a transfer plate 11 and a support 13 that supports the transfer plate 11 from below. The transfer plate 11 is arranged in the space between the two opposing chains 32 and 42. The support 13 is located below the transfer plate 11 and is arranged between the upstream conveyor 30 and the downstream conveyor 40. The support 13 supports the transfer plate 11 at its upper end, while its lower end is supported by the swing lever 23 of the elevating mechanism 20 described later. At the lower end of the support 13, a means for suppressing the frictional force with the swing lever 23, for example, a roller can be provided. The lower end of the support 13 supported by the swing lever 23 of the elevating mechanism 20 functions as an action point 26 by the swing lever 23 that functions as a lever.

The transfer plate 11 is a member made of a metal material having a rigidity such that it does not easily deform even when the container 100 is placed on it, for example, stainless steel.
The upper surface 11A of the transfer plate 11 is formed of a flat surface, and the upper surface 11A is parallel to the horizontal direction. The upper surface 11A functions as a delivery surface for delivering the container 100 from the upstream conveyor 30 to the downstream conveyor 40. Therefore, in the following, the upper surface 11A will be referred to as the delivery surface 11A. The cross section of the transfer plate 11 has an inverted triangular shape, but this is just an example.

Like the transfer plate 11, the support 13 is a member made of a metal material having a rigidity such that the container 100 is not easily deformed even when placed on the transfer plate 11, for example, stainless steel. In the present embodiment, a guide 15 for supporting the support 13 from the front-rear direction is provided so that the support 13 is not deformed such as bending in the front-rear direction. The guide 15 is provided so as to sandwich the support 13 from the upstream U and the downstream D. In order to suppress the frictional force with the support 13, the guide 15 preferably takes means for suppressing the frictional force, such as forming a film having a small friction coefficient on the surface sliding with the support 13 or providing a rolling element. ..

[Elevating mechanism 20]
The transfer plate device 10 includes an elevating mechanism 20 for elevating and lowering the transfer plate 11 and the support 13. The elevating mechanism 20 elevates the transfer plate 11 and the support 13 by using the eccentric cam 21 and the swing lever 23. The elevating mechanism 20 includes an eccentric cam 21 and a swing lever 23 that swings in the vertical direction V by the eccentric cam 21.
The eccentric cam 21 is coaxially fixed to the sprocket 34 of the upstream conveyor 30, and rotates with the driving force of the upstream conveyor 30.
The swing lever 23 is provided with a fulcrum 25, an action point 26, and a force point 27 from the downstream side D, and functions accordingly. The swing lever 23 in the present embodiment receives a load upward on the side of the force point 27 by a mechanism (not shown). At the fulcrum 25, the swing lever 23 is supported so as to be capable of forward and reverse rotation. At the point of action 26, the swing lever 23 supports the support 13 so that it can be relatively displaced. Further, at the force point 27, the swing lever 23 comes into contact with the eccentric cam 21, and receives a load corresponding to the rotation angle of the eccentric cam 21 downward.

Since the elevating mechanism 20 has the above configuration, the swing lever 23 swings with the rotation of the eccentric cam 21 while the upstream conveyor 30 is driven. As shown in FIG. 1A, in the process of swinging motion, when the force point 27 of the swinging lever 23 is at the highest position, the transfer plate 11 also reaches the highest position. Further, as shown in FIG. 1B, when the force point 27 of the swing lever 23 is at the lowest position in the process of the swing motion, the transfer plate 11 also reaches the lowest position. This highest position corresponds to the first position in the present invention, and the lowest position corresponds to the second position in the present invention. The transfer plate 11 descends from the first position to the second position ((a) → (b)), as shown in FIGS. 2 (a), (b), (c), and (d). The ascending / descending motion of ascending from the second position to the first position ((b) → (c)) and descending from the first position to the second position ((c) → (d)) is repeated.
The elevating mechanism 20 is only an example of the present invention, and as will be described later, the transfer plate 11 can be elevated by elements other than the cam and the swing lever. Further, even if a cam is used, a cam other than the eccentric cam can be used.

[Upstream conveyor 30 and downstream conveyor 40]
Next, the upstream side conveyor 30 and the downstream side conveyor 40 will be described.
Each of the upstream side conveyor 30 and the downstream side conveyor 40 is composed of, for example, a top plate chain conveyor, and a plurality of containers 100 are placed in the width direction W and conveyed toward the downstream side D.
Nose bars that slide on the chains 32 and 42 to guide the chains 32 and 42 may be provided at the ends of the downstream side D of the upstream conveyor 30 and the upstream side U of the downstream conveyor 40. The upper surfaces of the chains 32 and 42 form a transport surface 30A of the upstream conveyor 30 and a transport surface 40A of the downstream conveyor 40, respectively.

The upstream conveyor 30 includes a drive source 33 for driving the chain 32 and a sprocket 34 fixed to the output shaft of the drive source 33, and the chain 32 is wound around the sprocket 34. Similarly, the downstream conveyor 40 includes a drive source 43 for driving the chain 42 and a sprocket 44 fixed to the output shaft of the drive source 43, and the chain 42 is wound around the sprocket 44. The upstream conveyor 30 and the downstream conveyor 40 are provided with sprockets (not shown) in which the chains 32 and 42 are wound around the sprockets 34 and the sprockets 44, and apply the necessary tension to the chains 32 and 42. ..

The eccentric cam 21 is fixed to the output shaft of the drive source 33 of the upstream conveyor 30. When the drive source 33 is rotationally driven to operate the upstream conveyor 30, the eccentric cam 21 rotates together with the sprocket 34. The eccentric cam 21 can be rotated while the upstream conveyor 30 is operating. For example, by providing a clutch between the output shaft 33A and the eccentric cam 21, the eccentric cam 21 can be rotated for an arbitrary period. You can also let it.
Although the example in which the transfer plate 11 is raised and lowered by the driving force of the upstream conveyor 30 is shown here, the transfer plate 11 can also be raised and lowered by the driving force of the downstream conveyor 40.

[Relationship between delivery surface 11A and transfer surfaces 30A and 40A]
The delivery surface 11A of the transfer plate 11 is preferably set so as to coincide with or be lower than the transfer surface 30A of the upstream conveyor 30 and the transfer surface 40A of the downstream conveyor 40. When set low, the difference between the delivery surface 11A and the transfer surfaces 30A and 40A is several mm.

Here, when the transfer plate 11, the support 13, the upstream side conveyor 30, and the downstream side conveyor 40 are manufactured on an industrial production scale, dimensional errors occur in each of them. In addition, an error may occur in the setting when assembling these. Then, even in one transfer plate 11, the transfer surface 11A may have a portion located above the transfer surfaces 30A and 40A. As a result, the container 100 may not be delivered to the downstream conveyor 40 while the container 100 is transferred from the upstream conveyor 30 to the transfer plate 11. In particular, the container 100 having a small diameter or width and located at the rearmost position may remain on the transfer plate 11.

As shown in FIG. 4A, a plurality of containers 100 are arranged side by side and the adjacent containers 100 and the container 100 are transported while being in contact with each other. In FIG. 4, the container 100 is transported in the direction indicated by the white arrow.
As shown in FIGS. 4A and 4B, when the container 100 rides on the transfer plate 11, the container 100 cannot come into contact with either the upstream conveyor 30 or the downstream conveyor 40. Therefore, the container 100 cannot receive the conveying force from the upstream conveyor 30 and the downstream conveyor 40. In particular, if the delivery surface 11A is higher than the transfer surfaces 30A and 40A, this tendency becomes difficult. The transporting force means a load that the container 100 receives from the upstream U toward the downstream D and is sufficient for transporting the container 100. However, if there is a subsequent container 100 that is upstream U from the container 100 that rides on the transfer plate 11 and is placed on the upstream conveyor 30, the subsequent container 100 receives a conveying force from the upstream conveyor 30. Therefore, the container 100 that rides on the transfer plate 11 is transferred from the transfer plate 11 to the downstream conveyor 40 by receiving a conveying force from the container 100 that follows it.

However, as shown in FIG. 4C, the rearmost container 100 painted in gray cannot receive the conveying force from the subsequent container 100, and therefore remains on the transfer plate 11.
In order to avoid the residue of the container 100, the transfer plate 11 may be provided so that the transfer surface 11A of the transfer plate 11 is lower than the transfer surfaces 30A and 40A in any portion in consideration of the dimensional error. .. However, according to this workaround, there is a portion where the step between the transport surfaces 30A and 40A and the transfer surface 11A of the transfer plate 11 becomes large. The container 100 passing through this portion may fall into this step and fall when it is delivered from the transport surface 30A, and may hit this step and fall when it is delivered to the transport surface 40A. is there.

[Container 100 with a large diameter or width]
By the way, as shown in FIG. 5A, the container 100 having a large diameter or width is in contact with the upstream conveyor 30 on the upstream side U even if the container 100 rides up to the point where the transfer plate 11 and the central axes of each other coincide with each other. On the downstream side D, it contacts the downstream side conveyor 40. Therefore, as shown in FIG. 5B, the container 100 having a large diameter or width is delivered to the downstream conveyor 40 after removing the transfer plate 11.

[Up and down operation of the transfer plate 11]
In the present embodiment, the transfer plate 11 is raised and lowered. The action of raising and lowering the transfer plate 11 will be described with reference to FIG.
As shown in FIG. 6A, it is assumed that the rearmost container 100 rides on the transfer plate 11. Up to this point, FIG. 6A is reached in the same manner as in FIGS. 4A to 4C, the delivery surface 11A of the transfer plate 11 is at the same height as the transfer surfaces 30A and 40A, and the transfer surface 11A The transport surfaces 30A and 40A are flush with each other. The position of the transfer plate 11 is an example of the first position of the present invention. The container 100 is separated from both the upstream conveyor 30 and the downstream conveyor 40, and remains on the transfer plate 11 as it is. The first position in the present invention has significance as a normal position in which the transfer plate 11 that is stationary without moving up and down is arranged. This normal position coincides with the transport surfaces 30A and 40A, or is about several mm below the transport surfaces 30A and 40A.

According to this embodiment, the transfer plate 11 is lowered as shown in FIG. 6 (b). Then, the edge E1 of the upstream side U and the edge E2 of the downstream side D on the bottom surface of the container 100 come into contact with the upstream side conveyor 30 and the downstream side conveyor 40, and the container 100 receives the conveying force from the upstream side conveyor 30 and the downstream side conveyor 40. .. In particular, since the distance between the chain 32 and the chain 42 becomes narrower downward from the transport surfaces 30A and 40A, the container 100 tends to come into contact with the chain 32 and the chain 42 when the transfer plate 11 is lowered. Moreover, as shown in FIG. 6C, the lowering transfer plate 11 starts to rise, so that the container 100 is lifted. In this way, as shown in FIG. 6D, the container 100 is delivered to the downstream conveyor 40 without remaining on the transfer plate 11.

Here, an example in which the container 100 rides on the transfer plate 11 has been described, but when the transfer surface 11A of the transfer plate 11 is higher than the transfer surfaces 30A and 40A, the container 100 hits the transfer plate 11 and the transfer plate 11 You can't even get on. According to the transport device 1 provided with the transfer plate 11 that moves up and down, even in such a case, by lowering the transfer plate 11, the container 100 can be prevented from hitting the transfer plate 11 and the container 100 can be passed without difficulty. it can.

[Specific example of the range of raising and lowering the transfer plate 11]
As described above, the transfer surface 11A of the transfer plate 11 preferably coincides with or is lower than the transfer surfaces 30A and 40A. However, depending on the dimensional accuracy of the actually manufactured transfer plate 11, a portion where the transfer surface 11A is higher than the transfer surfaces 30A and 40A may occur, as shown in FIG. 7 (a-1). However, even in such a case, as the transfer plate 11 is lowered, a portion where the transfer surface 11A is lower than the transfer surfaces 30A and 40A is formed as shown in FIG. 7A-2. By doing so, even if the container 100 has a small diameter or width, it is suppressed that it remains on the transfer plate 11 as the tail end in the transport direction L.

Further, as shown in FIG. 7 (b-1), there may be a portion where the delivery surface 11A is lower than the transfer surfaces 30A and 40A. Also in this case, as the transfer plate 11 is lowered, the transfer surface 11A remains lower than the transfer surfaces 30A and 40A, as shown in FIG. 7 (b-2). By doing so, the container 100 having a small diameter or width is prevented from remaining on the transfer plate 11 as the tail end in the transport direction L.

The position of the transfer plate 11 shown in FIG. 7 (a-1) corresponds to the first position of the present invention, and the position of the transfer plate 11 shown in FIG. 7 (a-2) is the second position of the present invention. Corresponds to. It is assumed that FIGS. 7 (a-1) and 7 (a-2) are a part of the transfer plate 11 in the width direction W. Therefore, in other parts of the transfer plate 11, the transfer surface 11A may be flush with the transfer surfaces 30A and 40A, and the transfer surface 11A may be below the transfer surfaces 30A and 40A. That is, the first position and the second position in the present invention may exist in a plurality of positions on one transfer plate 11 as absolute values, but only one in each of the ascending / descending ranges.

[Effect of transport device 1]
Next, the effect of the transfer device 1 according to the present embodiment described with reference to FIGS. 1 to 7 will be described.
In the transfer device 1, it is assumed that the container 100 is placed on the transfer surface 30A of the upstream conveyor 30 and conveyed, and the last container 100 rides on the transfer surface 11A of the transfer plate 11. However, even the container 100 in which the transfer plate 11 is lowered and rides on the transfer surface 11A can receive the conveying force from one or both of the upstream side conveyor 30 and the downstream side conveyor 40. Therefore, the rearmost container 100 is suppressed from remaining on the transfer plate 11 and is delivered to the downstream conveyor 40. Therefore, the work of removing the remaining container 100 by the worker can be omitted.

In the transfer device 1, the transfer plate 11 descends from the first position to the second position, and when it descends to the second position, it rises to the first position, and so on. Here, the first position can be regarded as a normal position in which the transfer plate 11 that stands still without going up and down is arranged. That is, the main purpose of the transport device 1 is to arrange the transfer plate 11 at the first position, which is a normal position, and lower it to the first position. By doing so, the container 100 is brought into contact with one or both of the upstream conveyor 30 and the downstream conveyor 40, and the container 100 receives the conveying force.

The elevating mechanism 20 according to the present embodiment can repeat the elevating operation of the transfer plate 11 by the driving force of the upstream conveyor 30. Therefore, it is not necessary to provide an independent power source for the raising and lowering operation of the transfer plate 11, which is advantageous in terms of cost.

Although the preferred embodiments of the present invention have been described above, the configurations listed in the above embodiments can be selected or appropriately changed to other configurations as long as the gist of the present invention is not deviated.

It is preferable that the amount of elevation of the transfer plate 11 of the transfer plate device 10 can be adjusted. This is because it is necessary to adjust the lifting amount according to the size and shape of the container 100, and it is necessary to adjust the lifting amount according to the aged deterioration of the transfer plate device 10.
In the transfer plate device 10 of the present embodiment, as shown in FIG. 8A, by changing the position of the action point 26 of the support 13 on the swing lever 23, the transfer plate 11 via the support 13 The amount of lift can be adjusted. That is, as shown in FIG. 8A, the distance L from the fulcrum 25 to the force point 27 and the distances L1 and L2 from the fulcrum 25 to the action point 26 are set. However, L1> L2. In this case, the longer the distance L1 from the fulcrum 25 to the point of action 26, the larger the amount of elevation can be.

Further, as shown in FIG. 8B, the support 13 is divided into an upper support 13A and a lower support 13B, and a bolt 14A is fixed to the upper end of the upper support 13A and a bolt is attached to the lower end of the lower support 13B. Fix 14B. Then, the bolt 14A and the bolt 14B are connected by the high nut 14C. By rotating the high nut 14C, the position of the transfer surface 11A of the transfer plate 11 in the vertical direction V can be adjusted.
If a plurality of mechanisms shown in FIG. 8B are provided in the width direction W, the position of the transfer surface 11A in the width direction W of one transfer plate 11 can be individually adjusted. The same applies to the mechanism shown in FIG. 8 (c).

Further, as shown in FIG. 8C, the support 13 is divided into an upper support 13A and a lower support 13B. The lower end of the upper support 13A and the upper end of the lower support 13B are connected by fastening means such as bolts and nuts. If the hole through which the fastening means is passed is an elongated hole along the vertical direction V and the length of the overlapping portion between the lower end portion of the upper support 13A and the upper end portion of the lower support 13B is adjusted, the length of the transfer plate 11 is vertical. The position of the direction V can be adjusted.

Further, in the above-described embodiment, the elevating mechanism 20 repeats the elevating operation by the driving force of the downstream conveyor 40, but the present invention is not limited to this. That is, the present invention allows a dedicated drive source independent of the drive force of the upstream conveyor 30 or the downstream conveyor 40.

For example, as shown in FIG. 9A, the support 13 can be supported by the air cylinder 28 and the transfer plate 11 can be raised and lowered. In this embodiment, the lifting amount of the transfer plate 11 can be adjusted by adjusting the stroke of the piston of the air cylinder 28.

Further, as shown in FIG. 9B, the support 13 can be directly supported by the eccentric cam 29. In this embodiment, the amount of lift of the transfer plate 11 can be adjusted by raising and lowering the drive source that drives the eccentric cam 29.

Further, the transfer plate 11 is not limited to the inverted triangular shape shown in FIGS. 1 and 2. For example, an inverted trapezoidal shape as shown in FIG. 10A and an inverted triangular shape as shown in FIG. 10B but with curved hypotenuses can be applied. Further, as shown in FIG. 10 (c), the stepped shape may be inverted, and as shown in FIG. 10 (d), a plurality of ribs may be provided on the lower surface of the flat plate member.

Further, in the present invention, the operation of the transfer plate 11 by the elevating mechanism 20 can be continuously repeated for a period in which the container 100 is transferred from the upstream side conveyor 30 to the downstream side conveyor 40 to the downstream side D. .. Further, in the present invention, the operation of the transfer plate 11 by the elevating mechanism 20 can be repeated only for a specific period during which the container 100 is delivered to the downstream D. This is based on the fact that when a plurality of containers 100 are transported, residue is likely to occur in the last container 100. That is, when the last container 100 reaches the transfer plate 11, the operation by the elevating mechanism 20 can be started.
