Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reversing device for performing a reversing operation of reversing a transported object when transporting the transported object in the same direction along a linear transport line.

[0002]

2. Description of the Related Art In a production site for processed foods and the like, there is a case where it is necessary to perform a reversing operation for inverting a conveyed object such as a product or a semi-finished product in a process of conveying the conveyed object. This point will be described using a processed pudding in a plastic container as an example.

First, processed pudding is filled into a cup-shaped plastic container at about 80 degrees. And it is covered with a sheet-like member called a top seal. The top seal and the edge of the opening of the plastic container are bonded together with an adhesive or the like. Next, the plastic container is cooled to relieve the heat of the processed pudding filled at about 80 degrees. Cooling is performed with the top seal side facing down to prevent a change in the properties of the contents. For this reason, it is necessary to invert the plastic container before cooling. After the plastic container is cooled, a pinhole inspection is performed to check whether a hole is formed in the top seal.
Since the pinhole inspection is performed with the top seal side facing upward, the container must be turned over again before this inspection.

A conventional reversing device is disclosed in JP-A-6-80.
No. 234 and JP-A-6-48552. The reversing device disclosed in JP-A-6-80234 is configured to perform a reversing operation by dropping an object to be conveyed along a conveyance guide protruding in a semi-loop shape. However, according to this configuration, the transport direction of the transported object after the reversal is opposite to that before the reversal. In the reversing device used in such a production site, the direction of the conveyed object is determined by the layout of the production line, and usually, the reversing device is disposed along a straight conveying line between a certain production machine and a certain production machine. In many cases, a reversal operation is performed when a conveyed object is conveyed. That is, it is often not possible to use an object in which the direction of conveyance of the transferred object is changed after the reversing operation.

In Japanese Patent Application Laid-Open No. 6-48552,
As shown in FIG. 2, a swingable arm is provided, and after the reversing operation, the object to be transported is once mounted on the arm,
Thereafter, the transported object is placed on another belt conveyor. However, separately providing a mechanism having such an arm and a driving portion thereof requires a large space and increases the cost. Furthermore, the impact applied to the transferred object during the transfer operation by the arm is large, and the surface may be scratched or the contents may be damaged.

As other reversing devices, there are devices called a spiral type and a batch sandwich type. The spiral type has a configuration in which a product is moved while sliding along a spiral frame and turned over. The spiral type has a drawback that the frame needs to be arranged with high accuracy according to the shape of the transferred object, and the cost is likely to increase. In addition, it is impossible to convey objects having different shapes, and there is a disadvantage that versatility is lacking. Further, since a frictional force acts between the transferred object and the spiral frame, the transfer may not be performed properly depending on the material and state of the surface of the transferred object.

[0007] The batch sandwich type has a configuration in which a predetermined amount of a product is stored, sandwiched between two plates, and the reversal is performed collectively. This batch sandwich type has problems such as a problem that the flow of the product is not continuous and the subsequent handling is intermittent, and the productivity is poor.

In the present specification, a location where one transported object 9 first reaches when one transported object 9 is transported is referred to as “front stage”, and a location where the transported object 9 reaches afterwards is referred to as “back stage”. In.

The reversing section is constituted by a cylinder 1 having both ends open. The cylindrical body 1 protrudes in a semi-loop shape along a plane whose central axis is perpendicular and in a direction 90 ° lateral to the direction of conveyance of the article 9 to be conveyed.
Note that a front-stage linear conveyor 7 that conveys the transferred object 9 along a straight conveyance line is provided on the front side in the conveyance direction of the reversing device of the present embodiment, and on the rear side in the conveyance direction of the reversing device, A rear-stage linear conveyor 8 that transports the article 9 along a linear transport line in the same direction as the front-stage linear conveyor 7 is provided.

Next, the configuration of the inverting section will be described in more detail with reference to FIGS. FIG. 2 is a schematic sectional view illustrating the configuration of the reversing unit of the reversing device shown in FIG. The cross section in FIG. 2 is a cross section in a direction perpendicular to the transport direction.

As can be seen from FIGS. 1 and 2, the cylindrical body 1 protruding in a half-loop shape has an inner reversing plate 11 located on the inner side as viewed from the center of the half loop and an outer reversing plate 12 located on the outer side. The inner reversing plate 11 and the outer reversing plate 12 are connected to each other.

As shown in FIG. 2, the inner reversing plate 11 has an inner flat plate portion 111 in a horizontal posture and the inner flat plate portion 111.
, And a flat portion 113 provided to extend vertically downward from the lower end of the inner taper portion 112.
And an inner arc-shaped portion 114 provided so as to extend in an arc shape diagonally inward and downward from the lower end of the vertical portion 113.

Further, the outer reversing plate 12 is
Inner flat plate portion 111 so as to be parallel to the inner flat plate portion 111.
An outer first flat plate portion 121 provided above the outer first flat plate portion 121; an outer taper portion 122 provided to extend obliquely downward from an end of the outer first flat plate portion 121 in parallel with the inner tapered portion 112; Arc-shaped outer arc-shaped portion 1 provided to extend obliquely downward from the end of the portion 122
23 and an outer second flat plate portion 124 provided to extend horizontally inward from the end of the outer arc-shaped portion 123.

The cross-sectional shape of the cylindrical body 1 according to the above configuration is rectangular, and the size of the cross-section is slightly larger than the width and height of the load 9. When the transported object 9 enters the cylinder 1, the transported object 9 moves while sliding on the inner reversing plate 11, and falls on the outer reversing plate 12 while dropping along the axial direction of the cylinder 1 by gravity. On. When the transported object 9 moves while falling along the center axis of the half loop in the cylindrical body 1 in this manner, the transport object 9 is turned upside down.

Next, a description will be given of the configuration of the front part and the rear part which constitute another major feature of this embodiment. As can be seen from the above description, in the reversing device of the present embodiment, the cylindrical body 1 constituting the reversing part projects in the direction perpendicular to the transport direction, and the upper end opening and the lower end opening thereof extend in the horizontal direction perpendicular to the transport direction. It is suitable. The front part turns the direction of conveyance of the transferred object 9 conveyed along the linear conveyance line by the front linear conveyor 7 by 90 degrees, and the transferred object 9 enters the cylindrical body 1 from the upper end opening. To make it possible.
Also, the rear part turns the direction of the transferred object 9 that has been inverted inside the cylindrical body 1 and comes out from the lower end opening by 90 degrees, and the transferred object 9 is oriented in the same direction as the front linear conveyor 7 by the rear linear conveyor 8. To be transported to

More specifically, the front section is provided with a front curve conveyor 2 for conveying the article 9 along a 90-degree arc-shaped conveyance line. FIGS. 1 and 3 show the configuration of the front curve conveyor 2.
This will be described using. FIG. 3 is a schematic plan view of the reversing device shown in FIG.

The front curve conveyor 2 comprises a front curve belt 21 and a front drive mechanism (not shown) for driving the front curve belt 21. Front curve belt 2
Reference numeral 1 denotes a configuration in which both ends of a band-shaped member are connected to form a ring. However, the length of one edge of the belt is considerably longer than that of the opposite edge. Therefore, as seen from FIGS. 1 and 3, the contour of the front-stage curve belt 21 has a shape composed of two concentric 90-degree arcs and a line connecting both ends thereof, as can be seen from FIGS. 1 and 3.

The drive mechanism (not shown) for driving the front curve belt 21 mainly includes a drive roller (not shown) provided inside the front curve belt 21 and a drive source (not shown) for driving the drive roller. ing. The drive roller rotates around a horizontal rotation axis, and a plurality of drive rollers are provided in a radial direction of an arc at a front end portion in the conveying direction and a rear end portion in the conveying direction of the front curve belt 21. .

Each drive roller is adapted to rotate at a different predetermined rotational speed according to the position in the radial direction. That is, the drive roller at a position near the center of the arc rotates at a low speed, and the drive roller at a position far from the center rotates at a high speed. As a result, the front curve belt 21 is configured to rotate along a line that is long in a horizontal direction when viewed from the side and is a 90-degree arc in plan view. With the rotation, the transferred object 9 placed on the front curve belt 21 is carried along a 90-degree arc-shaped transfer line.

The front curve conveyor 2 is provided with a front conveyor guide 22 for preventing the transferred object 9 placed on the upper surface of the front curve belt 21 from coming off the transfer line. As such a front-stage curve conveyor 2, for example, MBC3 manufactured by Maruyasu Machine Co., Ltd.
Etc. can be adopted.

The upper surface of the front curve belt 21 is flush with the upper surface of the belt of the front linear conveyor 7. The front end of the front curve belt 21 in the conveying direction is located at a position close to a rear end of the linear conveyor 7 in the conveying direction with a predetermined gap. The upper surface of the front curve conveyor 2 is flush with the inner flat portion 111 of the inner reversing plate 11, and the rear end of the front curve belt 21 in the transport direction is closer to the front end of the inner flat portion 111 in the transfer direction. At a predetermined gap. For this reason, the transported object 9 is transported along a linear transport line by the linear conveyor 7 at the former stage, then is placed on the former curved belt 21 and moves along the transport line having a 90-degree arc. After that, it is placed on the inner flat portion 111 of the inner reversing plate 11 and enters the inside of the cylindrical body 1.

On the other hand, the rear part also has a rear curve conveyor 3. The rear-stage curve conveyor 3 has the same configuration as the front-stage curve conveyor 2 except for the place where the rear-stage curve conveyor is provided and the transport line, and includes a rear-stage curve belt 31, a driving mechanism (not shown) for driving the rear-stage curve belt 31, and a rear-stage conveyor guide 32. .

The rear curve conveyor 3 is provided directly below the front curve conveyor 2 as can be seen from FIG.
As can be seen from FIGS. 1 and 3, when viewed from above, the arc-shaped transport line of the rear curve conveyor 3 is obtained by moving the transport line of the front curve conveyor 2 vertically downward and rotating it 270 degrees clockwise. Has become.

The upper surface of the rear curve belt 31 provided in the rear curve conveyor 3 is flush with the upper surface of the outer second flat plate portion 124 of the outer reversing plate 12, and is located on the front side in the transport direction of the rear curve belt 31. End and outer second flat plate portion 12
4 is closer to the rear end in the transport direction with a predetermined gap. The upper surface of the rear curve belt 31 is flush with the upper surface of the belt of the rear straight conveyor 8, and the rear end of the rear curve belt 31 in the conveying direction is the rear straight conveyor 8.
Is located close to the end of the front side in the transport direction with a predetermined gap. Therefore, as described above, the transported object 9 inverted in the cylindrical body 1 is placed on the rear-stage curved belt 31 and transported along a 90-degree arc-shaped transport line, and is transferred onto the belt of the rear-stage linear conveyor 8. It comes to be.

The configuration in which the transport direction of the transported object 9 is changed by 90 degrees between the entrance and the exit of the cylindrical body 1 can be achieved without providing a special mechanism such as the above-mentioned curve conveyor. For example, a wall perpendicular to the transport direction is provided on the rear side of the front linear conveyor 7. Then, an inclined plate that is inclined obliquely downward and perpendicular to the transport direction is provided between the wall and the front-stage linear conveyor 7. Further, the lower end of the inclined plate is provided near the lower edge of the upper end opening of the cylindrical body 1 or connected to the lower edge.
The transferred object 9 conveyed by the front-stage linear conveyor 7 slid on the inclined plate after colliding with the wall, and moves from the upper end opening to the cylindrical body 1.
To enter. The same applies to the rear part, where a wall is provided so that the transferred object 9 coming out of the lower end opening of the cylindrical body 1 collides, and an inclined plate is provided obliquely downward from the position of the wall. Then, the transported object 9 slides on the inclined plate and is placed on the belt of the subsequent straight conveyor 8.

However, in the above-described configuration, there is a problem in that a large impact is applied to the transferred object 9 because the direction of the transfer of the transferred object 9 is changed by colliding with the wall. In addition, since the movement of the transferred object 9 after colliding with the wall is not constant,
There is also a problem that the transport operation when sequentially transporting the transported objects 9 becomes unstable.

On the other hand, as in the present embodiment, when the cartridge 1 is moved in and out of the cylinder 1 while being conveyed along a 90-degree arc-shaped conveyance line by a curved conveyor, there is no impact on the object 9 to be conveyed, and the conveyance operation can be performed. Stabilize. Therefore, the reversing device has high reliability.

In this embodiment, in order to further reduce the impact applied to the transported object 9, the speed of the transported object 9 when entering the cylindrical body 1 from the upper end opening of the cylindrical body 1 is reduced. A speed reduction unit and a rear-stage speed reduction unit that slows down the speed of the transferred object 9 when it is conveyed by the rear curve conveyor 3 after exiting from the lower end opening of the cylindrical body 1 are provided. In particular,
The former reduction portion is the inner flat plate portion 111, and the latter reduction portion is the outer second flat plate portion 124.

The upper surface of the inner flat plate portion 111 is provided so as to be flush with the upper surface of the former curved belt 21 as described above. On the top. Inner flat plate 1
On the object 11, no moving force is applied to the transferred object 9, and the transferred object 9 slides on the inner flat plate portion 111 due to inertia. At this time, a suitable frictional force is generated between the inner flat plate portion 111 and the transferred object 9, and the transferred object 9 is decelerated to an appropriate speed by the frictional force.

The transported object 9 falls on the inner tapered portion 112 from the inner flat plate portion 111 by gravity while sliding on the inner tapered portion 112. Then, the transferred object 9 performs a reversing operation while colliding with the outer circular portion 123 of the outer reversing plate 12 and sliding on the outer circular portion 123. At this time, if the falling speed of the transferred object 9 is high, the outer reversing plate 12
The impact at the time of collision may increase, and the surface of the transferred object 9 may be damaged or the contents may be damaged. However, in the present embodiment, there is no such fear because the speed is reduced to an appropriate speed by the inner flat plate portion 111. Note that the length of the inner flat plate portion 111 as viewed in the moving direction of the transferred object 9 is important for sufficient deceleration. This length is, for example, about 20 mm, depending on the transport speed of the transported object 9 in the former-stage curve conveyor 2.

The configuration of the inner tapered portion 112 also contributes to the reduction of the load 9. That is, as can be seen from FIG. 2, the inner tapered portion 112 has a flat plate shape and comes into surface contact with the transferred object 9. Therefore, even in the inner tapered portion 112, a large frictional force is generated.
While sliding on the inner tapered portion 112,
The transported object 9 has a deceleration effect due to friction with the inner tapered portion 112. As a result, the speed of the transferred object 9 when reaching the vertical portion 113 from the inner tapered portion 112 and dropping downward is further reduced, and the outer arc-shaped portion 1 is reduced.
The impact applied to the transferred object 9 when colliding with 23 is further reduced.

On the other hand, the outer second flat plate portion 124 as a reduction portion provided at the lower end opening of the cylindrical body 1 decelerates the transported object 9 that has fallen to perform the reversing operation and transfers it to the rear curve conveyor 3. It is configured as follows. Outer second flat plate part 1
Reference numeral 24 denotes a flat plate having a horizontal posture similar to the inner flat plate portion 111. The flat plate 24 is adapted to decelerate the transferred object 9 by applying a frictional force to the transferred object 9 which is slid on the upper surface. Conveyed object 9
Is transferred onto the rear curve belt 31 of the rear curve conveyor 3 in a sufficiently decelerated state, so that the transfer operation becomes smooth. If the speed is not sufficiently reduced, there is a problem that the transferred object 9 rolls on the rear curve belt 31 or collides strongly with the rear conveyor guide 32.
Note that the length of the outer second flat plate portion 124 is
Similarly to the above, for example, it may be about 20 mm.

Hereinafter, the overall operation of the reversing device of the present embodiment will be schematically described. First, the transported object 9 is transported along a linear transport line by the front-stage linear conveyor 7. The conveyed object 9 is placed on a front curve belt 21 from the belt of the front linear conveyor 7, conveyed along a 90-degree arc-shaped conveyance line, and turned into a cylindrical body 1 of a reversing part.
From the upper end opening of the cylindrical body 1. At this time, as described above, the transferred object 9 is decelerated by sliding on the inner flat plate portion 111. Then, while being further decelerated by sliding on the inner tapered portion 112, the transported object 9 falls in the cylindrical body 1 and reverses. Then, the transported object 9 is decelerated by the outer second flat plate portion 124 as described above, and then exits from the lower end opening of the tubular body 1 and is placed on the rear curve belt 31.
Then, the transferred object 9 is conveyed along a 90-degree arc-shaped conveyance line by the rear-stage curved belt 31, and then transferred to the belt of the rear-stage linear conveyor 8. Thereafter, the transferred object 9 is conveyed by the rear-stage linear conveyor 8 in the same direction as the front-stage linear conveyor 7.

In the configuration of the present embodiment described above, the deceleration section is configured so that the transferred object 9 slides on the flat plate portion and is decelerated by the frictional force. A configuration in which deceleration is performed by applying a force in the opposite direction may be employed. However, as compared with such a configuration, the configuration in which the deceleration portion is a flat plate portion has an advantage of simplifying the configuration of the device.
In some cases, it is sufficient to provide the speed reducer only at either the upper end opening or the lower end opening.

Further, as the cylindrical body 1 constituting the reversing part,
Instead of a rectangular tube-shaped member, a cylindrical shape or a tube having an elliptical cross section may be used. Further, the former-stage curve conveyor 2 and the latter-stage curve conveyor 3 are not limited to those conveyed by belts. The configuration is not particularly limited as long as the transported object 9 can be transported along a 90-degree arc-shaped transport line. In addition, the transported object 9 is not limited to the above-described processed food and the like, and may be anything as long as it needs to be inverted when transported along a linear transport line.

[0038]

As described above, according to the first aspect of the present invention, since the front curve conveyor and the rear curve conveyor are provided, it is possible to reverse the transport direction of the transported object without changing the transport direction. Further, the impact applied to the transported object can be reduced. Therefore, a highly reliable reversing device is provided. According to the second aspect of the present invention, in addition to the above effects, the speed at which the transported object enters the reversing section is reduced by the preceding-stage reduction section, so that the impact applied to the transported object at the time of reversing is reduced. The effect of further reduction is obtained. According to the invention of claim 3, in addition to the above effects,
Since the front-stage deceleration portion is a flat plate portion provided so as to form a part of the inner reversing plate, an effect that the configuration of the device is simplified can be obtained. According to the fourth aspect of the present invention, in addition to the above-described effects, the speed at which the conveyed object exits the reversing unit is reduced by the rear-stage reduction unit, so that the operation when the conveyed object is placed on the rear-stage curved belt is performed. And the effect that the impact applied to the transported object is small is obtained. According to the fifth aspect of the present invention, in addition to the above effects, the rear-stage reduction portion is a flat plate portion provided to form a part of the outer reversing plate, so that the configuration of the device is simplified.
