In the method, an air slide system is employed for the plate for transferring the container, which reduces friction between the bottom of the container and the surface of the plate for transferring by boring small holes on the surface of the plate in contact with the container and jetting pressurized air through the small holes, and the container can be transferred without falling down on a plate part for transferring the container.

Description

  The present invention relates to a belt-type conveyor that conveys containers such as bottles and cans, and arranges a container transfer plate between adjacent conveyors, and conveys the container while being pushed by the subsequent container on the container transfer plate. The present invention relates to a container transfer method between conveyors and a container transfer plate between conveyors.

In conveyors such as belts and cans that transport containers such as bottles and cans, it is necessary to divide the conveyor due to restrictions on equipment layout, etc., and in order to transfer containers to be transported between the divided conveyors, Specifically, a dead plate type container delivery plate as shown in FIG. 6 is often used.
In addition, as for a container transfer plate between conveyors such as belts that are parallel to each other, a technique is known in which containers are transferred between conveyors having different height positions. (Patent Document 1)
Furthermore, a technique for transporting containers between each production process using an air jet type conveyor device is also known. (Patent Document 2)

  On the other hand, in the container transfer plate between the front and rear conveyors of a belt type conveyor or the like, since the container transfer plate does not have a transfer force for transferring the container, the preceding container is transferred while being pushed by the subsequent container. In other words, when containers are transferred from the upstream conveyor to the downstream conveyor, there is a problem that the containers fall over the container transfer plate, and improvement is desired. In particular, in the aseptic filling and packaging line, when the conveyor and the container transfer plate are covered with a cover or the like to maintain a sterile atmosphere, when the container falls over the container transfer plate, the cover is opened, that is, in a sterile state. The container must be processed by releasing the container, and it takes a lot of time and labor to return to the aseptic condition again. Therefore, there is a demand for improvement to eliminate the container overturning at the container transfer plate part. Is strongly screamed.

Japanese translation of PCT publication No. 2008-504187 (FIG. 3) JP 2003-12148 A (FIGS. 1 and 3)

A conventional belt-type conveyor for conveying containers such as bottles and cans will be described with reference to FIGS.
FIG. 6 is a front view of a conventional inter-conveyor container transfer plate.
FIG. 7 is an explanatory view of a conventional inter-conveyor container transfer plate.
In the figure, a belt-type conveyor 31 comprising a driving roller 33 rotating in the direction of arrow 33c and a conveyor belt 31b suspended on a driven roller (not shown), and a driving roller (not shown) and a driven roller 34 rotating in the direction of arrow 34c. A belt type conveyor 32 composed of a conveyor belt 32b is arranged in the front and rear, and a dead plate type container delivery plate 30 is provided between the belt type conveyor 31 and the belt type conveyor 32.

  Next, the operation of the container transfer plate 30 will be described. The container C that has been conveyed on the conveyor 31 is pushed out toward the container transfer plate 30 by the conveying force of the conveyor belt 31b. The container C moves forward while being pushed by the container C, and is then conveyed while being pushed by the subsequent container C from the container transfer plate 30 to the conveyor 32 and is conveyed downstream by the conveyor 32.

  In the container transfer plate 30, as shown in FIG. 7A, when the container Cb is transferred from the conveyor belt 31b to the container transfer plate 30, the container Cb has a bottom end Ch and a location 30c of the container transfer plate 30. On the other hand, the rear end Ct of the bottom of the container Cb is pushed by the conveying force of the conveyor belt 31b, and the conveyor belt 31b and the container transfer plate 30 are brought into the conveying surface. When there is a slight level difference, the container Cb often falls in the direction of the arrow tb.

Further, as shown in FIG. 7B, when the container Cc reaches the conveyor belt 32b to transfer from the container transfer plate 30 to the conveyor belt 32b, there is a slight difference between the conveyor belt 32b and the transfer surface of the container transfer plate 30. However, there is a level difference, and there is a step between the portion 30d of the container transfer plate 30 and the conveyor belt 32b, so the tip Ch at the bottom of the container Cc is conveyed suddenly by the conveying force due to friction with the conveyor belt 32b. In addition, since the rear end Ct of the bottom of the container Cc staggers and falls on the stepped portion, the container Cc often falls in the direction of the arrow tc.
As described above, in the conventional dead plate type container passing plate, the container is likely to fall down at the front and rear portions of the container passing plate.

Further, according to the above-mentioned Patent Document 1, a product-type product storage device that stores products has a product path part (conveyor) and a storage part (conveyor) that are parallel to each other and have different height positions, from the product path part to the storage part. The product is moved by a transfer surface, which is a slide transfer medium extending at a downward angle, or by an air slide device that ejects a large amount of pressurized air from the surface of the air plenum chamber.
However, in the technique of Patent Document 1, the size of the transfer medium is increased for the functional purpose of moving products that cannot be properly aligned to the product conveyance downstream of the product path portion to the accumulation portion. A large amount of compressed air needs to be ejected from the surface of the plenum chamber, which may result in a large consumption of compressed air. Moreover, although the technique which moves a product with an air slide apparatus is disclosed, it is not disclosed about the technique in which a subsequent product is continuously conveyed while pushing the other product with an air slide apparatus.

Further, according to Patent Document 2, the air jet type conveyor device blows air fed from the blower into the plenum to the upper surface from a number of air jet holes of the deck plate, and the air flow allows the can on the deck plate surface. The container group is lifted and transported.
However, in the technique of Patent Document 2, a large amount of air from the sending machine is required, and the apparatus (blower) for producing the pressure air becomes large, which increases the apparatus cost and the consumption cost of the pressure air. There is a risk that will become enormous.
In the case of an aseptic filling and packaging line, if a large amount of air is ejected for transporting containers, the surrounding atmosphere on the deck plate may be disturbed, and sterility maintenance may not be maintained.

  In the present invention, when a conveyor that conveys containers on the conveyance surface is adjacent to each other, a container passing plate is disposed between the adjacent conveyors, and the container is pushed by a subsequent container and then passed from the upstream conveyor to the downstream conveyor.

In addition, constituent elements in the following embodiments include those that can be easily assumed by those skilled in the art or those that are substantially the same.
(First Embodiment of the Invention)

A first embodiment of the present invention will be described with reference to FIGS.
A first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a partial front view of a conveyor line incorporating an inter-conveyor container transfer plate according to a first embodiment of the present invention.
FIG. 2 is an enlarged view of the container delivery plate of FIG.
FIG. 3 is a view from A in FIG.
In the figure, an upstream conveyor 11 and a downstream conveyor 12 are arranged in series with the space between the two conveyors adjacent to each other as close as possible, and the container delivery plate 1 is arranged at the rear end of the conveyor 11. And the front end of the conveyor 12 as close as possible to the conveyor 11 and the conveyor 12, and the container C transported by the conveyor 11 advances while being pushed by the subsequent container to the conveyor 12. To be passed.
Although the upstream conveyor 11, the downstream conveyor 12, and the container transfer plate 1 are not illustrated, they are installed in a sterile atmosphere.

  The container delivery plate 1 has a chamber 1c and a pipe 1p connected so that aseptic pressure air (hereinafter referred to as air) is supplied to the chamber 1c from a sterile pressure air supply source (not shown) in the direction of arrow 1a. And small holes 1h and small holes 1h1 provided on the contact surface with the container C (conveying surface of the container C), and the air supplied into the chamber 1c is the small holes 1h and small holes 1h1. Is blown out to the outside as indicated by arrows 1f and 1f1, and the friction between the surface of the container C and the chamber 1c is reduced.

The small hole 1h1 is provided in the vicinity of the boundary portion between the upstream conveyor 11 and the downstream conveyor 12 of the container transfer plate 1, and as shown in the drawing, the conveyance direction of the container C on the surface in contact with the container C The air in the chamber 1c is ejected to the end of the boundary as much as possible, and the dead space at the end of the boundary is minimized. Has been.
The small hole 1h is a small hole having a round cross-sectional shape except for the vicinity of the boundary portion of the container passing plate 1.

Further, the conveyor 11 is configured such that a conveyor belt 11b suspended by a driving roller 13 rotating in the direction of an arrow 13c and a driven roller (not shown) travels and transports the container C on its transport surface. Further, the conveyor 12 travels on a conveyor belt 12b suspended from a driving roller (not shown) and a driven roller 14 that rotates in the direction of arrow 14c, and transports the container C on its transport surface. To the next process.
In the above description, the conveyor 11 and the conveyor 12 are described as belt-type conveyors. However, the conveyance body is not limited to a belt, but may be a conveyance body such as a chain having a top plate or the like.

Next, the operation of the inter-conveyor container transfer plate 1 according to the first embodiment of the present invention will be described.
When the container C is transferred from the upstream conveyor 11 to the container transfer plate 1, the container C tends to be pushed forward by the friction between the bottom of the container C and the conveyor belt 11b. 11, the friction between the container C and the contact surface of the container transfer plate 1 is small due to the air ejection from the small hole 1h1 provided in the vicinity of the boundary with the container 11, and the forward movement is smooth while being pushed by the subsequent container C. Passed to.
Here, there is a slight level difference between the conveyor 11 and the transfer surface of the container transfer plate 1, but the contact surface between the container C and the container transfer plate 1 is blown by the air jet from the small hole 1h1. Therefore, the container C is smoothly transferred from the upstream conveyor 11 to the container transfer plate 1 without falling down.

  While the preceding container C passed over the container transfer plate 1 is pushed by the subsequent container C, the friction between the bottom surface of the container C and the container transfer plate 1 is reduced by the air ejected from the small hole 1h. With the air slide method, it moves forward smoothly without falling.

Further, when the container C is transferred from the container transfer plate 1 to the downstream conveyor 12, the container C advances while being pushed by the subsequent container C, and the top of the bottom of the container C reaches the conveyor belt 12b. Friction between the container C and the contact surface of the container transfer plate 1 is small by the air ejection from the small hole 1h1 provided in the vicinity of the boundary between the container transfer plate 1 and the downstream conveyor 12, In addition to the pushing force by the subsequent container C, the sheet is transferred by the conveying force caused by the friction between the bottom of the container C and the conveyor belt 12b.
Here, although there is a slight level difference between the transport surfaces of the container transfer plate 1 and the conveyor 12, the contact surface between the container C and the container transfer plate 1 is ejected from the small holes 1h1. Therefore, the container C is smoothly passed from the container transfer plate 1 to the conveyor 12 without falling down.

The delivery of the container C in the container delivery plate 1 in an aseptic atmosphere must be performed by releasing the sterilization and processing the overturned container when the container is overturned. However, as described above, since the sterilization is not canceled because the container does not fall down as described above, the production efficiency is greatly improved, and a wasteful cost can be saved.
Further, since the length of the container transfer plate 1 in the conveying direction of the container C is the shortest, the amount of air ejected from the small holes 1h and the small holes 1h1, that is, the amount of air consumption can be reduced. In addition, the cost for air consumption can be reduced, and the surrounding atmosphere is not disturbed and the aseptic atmosphere is not adversely affected.

  In the above description, the case where the upstream conveyor 11, the downstream conveyor 12, and the container transfer plate 1 are installed in a sterile atmosphere has been described. However, the upstream conveyor 11, the downstream conveyor 12, and the container transfer plate 1 are Even when the container is installed in a non-sterile normal atmosphere, the container is not overturned when the container is transferred on the container transfer plate 1, so that the production efficiency is improved. Since the amount of air consumed from 1h and the small hole 1h1 is small, the cost for air consumption can be reduced.

(Second Embodiment of the Invention)
Next, a second embodiment of the invention will be described with reference to FIGS.
FIG. 4 is a partial plan view of a conveyor line incorporating inter-conveyor container transfer plates according to the second embodiment of the present invention.
FIG. 5 is a sectional view taken along the line BB in FIG. 4 and is an enlarged view.
In the figure, an upstream conveyor 21 and a downstream conveyor 22 are arranged in parallel adjacent to each other in the direction D in the drawing in the left-right direction with respect to the conveying direction of the conveyor, and a container delivery plate is provided between the conveyor 21 and the conveyor 22. 2 is arranged so that the containers C conveyed by the conveyor 21 are advanced and passed to the conveyor 22 while being pushed by the subsequent containers C.
The container delivery plate 2 is disposed between the conveyor 21 and the conveyor 22 that are disposed with a distance D due to layout constraints, but is provided as close as possible to the conveyor 21 and the conveyor 22. ing.
Moreover, although the illustration of the conveyor 21, the conveyor 22, and the container transfer plate 2 is omitted, they are installed in an aseptic atmosphere.

  The container passing plate 2 is connected to a chamber 2c and a pipe 2p connected so that aseptic pressure air (hereinafter referred to as air) is supplied to the chamber 2c from an aseptic pressure air supply source (not shown) in the direction of arrow 2a. And a small hole 2h and a small hole 2h1 provided on a surface in contact with the container C (conveying surface of the container C), and the air supplied into the chamber 2c is supplied from the small hole 2h and the small hole 2h1. As shown by arrows 2f and 2f1, the air slide method is employed in which friction between the surface of the container C and the chamber 2c is reduced by being ejected to the outside.

The small hole 2h1 is provided in the vicinity of the boundary portion between the upstream conveyor 21 and the downstream conveyor 22 of the container transfer plate 2, and is in contact with the container C as in the case of the first embodiment. The surface of the chamber 2c has an elliptical shape with a major axis in the conveying direction of the container C, and air in the chamber 2c is ejected to the end of the boundary as much as possible, and dead at the end of the boundary as much as possible. The space is made as small as possible.
The small hole 2h is a small hole having a round cross-sectional shape except for the vicinity of the boundary portion of the container passing plate 2.

Further, a container guide 27 and a container guide 28 are provided in the container transfer plate 2 part, and when the container C is transferred from the conveyor 21 to the container transfer plate 2, it is conveyed on the container transfer plate 2. And when being transferred from the container transfer plate 2 to the conveyor 22, it is guided by the container guide 28.
The container guide 27 is an auxiliary guide that prevents the container C from protruding outside when the container C is removed from the conveyance path.
The container guide 27 and the container guide 28 are made of a material having a small coefficient of friction with the container C.

  Further, the conveyor 21 is configured such that a conveyor belt 21b serving as a conveyance surface travels by a driving roller (not shown) and a driven roller (not shown) and conveys the container C in the direction of the arrow C1 from the upstream side. No. 22 is configured such that a conveyor belt 22b serving as a conveying surface travels by a driving roller (not shown) and a driven roller (not shown) to convey the container C, and the container C is fed in the direction of arrow C2.

Next, the operation of the inter-conveyor container transfer plate 2 according to the second embodiment of the present invention will be described.
When the containers C conveyed by the upstream conveyor 21 with a space between the containers are transferred from the conveyor 21 to the container transfer plate 2, the container guide 28 is caused by the frictional force caused by the friction between the bottom of the containers C and the conveyor belt 21b. The air is ejected from the small hole 2h1 provided in the vicinity of the boundary between the container transfer plate 2 and the upstream conveyor 21 in the direction of the arrow Cp. Thus, the friction between the container C and the contact surface of the container transfer plate 2 is small, and the container C is smoothly transferred while being pushed by the subsequent container C.
Here, although there is a slight level difference between the conveyor 21 and the transfer surface of the container transfer plate 2, the contact surface between the container C and the container transfer plate 2 is blown by the air ejection from the small hole 2 h 1. Therefore, the container C is smoothly transferred from the upstream conveyor 21 to the container transfer plate 2 without falling down.

The preceding container C passed over the container passing plate 2 is pushed by the succeeding container C, while the bottom surface of the container C and the container passing plate 2 are blown from the small holes 2h along the container guide 28. By the air slide method in which the friction between the head and the head is small, the head moves smoothly in the direction of the arrow Cq without falling down.
Further, when the container C is transferred from the container transfer plate 2 to the downstream conveyor 22, the container C advances while being pushed by the subsequent container C on the container transfer plate 2, and the top portion of the bottom thereof is the conveyor belt. Friction between the container C and the contact surface of the container delivery plate 2 due to air ejection from the small holes 2h1 provided in the vicinity of the boundary between the container delivery plate 2 and the downstream conveyor 22 In addition to the pushing force by the subsequent container C, the sheet is conveyed by the conveying force caused by the friction between the top of the bottom of the container C and the conveyor belt 22b, and passed while changing the conveying direction as shown by the arrow Cr. As described above, the container 22 is transported on the conveyor 22 in the direction of the arrow C2.
Here, although there is a slight level difference between the transport surfaces of the container transfer plate 2 and the conveyor 22, the contact surface between the container C and the container transfer plate 2 is ejected by the air jet from the small hole 2h1. Therefore, the container C is smoothly transferred from the container transfer plate 1 to the conveyor 22 without falling down.

The delivery of the container C in the container delivery plate 2 in an aseptic atmosphere requires that the sterilization is canceled and the overturned container is processed when the container is overturned. However, as described above, since the sterilization is not canceled because the container does not fall down as described above, the production efficiency is greatly improved, and a wasteful cost can be saved.
Further, since the length of the container transfer plate 1 in the conveying direction of the container C is minimized, the amount of air ejected from the small holes 2h and the small holes 2h1, that is, the amount of air consumption can be reduced. In addition, the cost for air consumption can be reduced, and the surrounding atmosphere is not disturbed and the aseptic atmosphere is not adversely affected.

  In the above description, the case where the upstream conveyor 21, the downstream conveyor 22, and the container transfer plate 2 are installed in a sterile atmosphere has been described. However, the upstream conveyor 21, the downstream conveyor 22, and the container transfer plate 2 are Even when the container is installed in a non-sterile normal atmosphere, the container is not overturned when the container is transferred on the container transfer plate 2, so that the production efficiency is improved. Since the amount of air consumed from 2h and the small hole 2h1 is small, the cost for air consumption can be reduced.
