Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aligning apparatus for reducing the number of rows of a group of articles conveyed by a plurality of rows by a conveyor and aligning the rows in a required number of rows.

[0002]

Generally, in a production factory in which the production process of a product includes a plurality of processes, the transfer of the production target between the processes is often performed by a conveyor.

For example, in a beverage bottling plant, a canning plant, a cosmetics plant, or the like, the production and shipping of products involves a process of filling the containers with the contents while the containers are conveyed by a conveyor. The process is performed through a plurality of production processes such as a process of covering a container, a process of attaching a label to a container, and a process of packing a product in a shipping case.

[0004] In each production process in such a production factory, it is necessary to appropriately change the transport mode of the product by the conveyor according to the respective processing mode, and depending on the production process, the product is carried into the production process. In some cases, it is necessary to reduce the number of rows of products to be conveyed before the operation is performed.

[0005] For example, in a filling process, a plugging process, a labeling process, and the like in a beverage bottling plant, it is necessary to arrange containers sequentially conveyed in a plurality of rows in a single row before being carried into each step. There is.

[0006] As described above, a conveyed article aligning apparatus that changes the conveyed form of conveyed articles conveyed in a plurality of rows by a conveyor as necessary and arranges the articles in a required number of rows is conventionally provided.
There is one described in JP-A-2-158514.

[0007] This conventional transported article aligning apparatus aligns two rows of beverage bottle containers transported by a conveyor in a single row and carries it into the next step. As shown in FIG. A pair of parallel guides 1a and 1b arranged on the three conveyor belts V1 'to V3' arranged in parallel to the conveying direction of the conveyor and guiding the bottle containers B in two rows; The belt conveyors V1 ′ to V1 ′ are connected to downstream ends of the parallel guides 1a and 1b, respectively.
A pair of skew guides 2a and 2b are arranged so as to be skewed in the conveyance direction of 3 'and become closer to each other toward the downstream side, and to a downstream end of each of the skew guides 2a and 2b. The bottle containers B are arranged so as to extend continuously and in parallel with the conveying direction of the belt conveyors V1 'to V3'.
A pair of single-row guides 3a and 3b for guiding the bottle containers B in a two-row state by the belt conveyors V1 'to V3' are provided. After being aligned in a single-row state by being squeezed by the skew guides 2a and 2b, the single-row guide 3
While being guided by a and 3b, it is carried into the next step.

[0008] The conventional conveyed article aligning apparatus includes one skew guide 2b of a pair of skew guides 2a and 2b.
An air cylinder 4 having both ends of a piston rod 4a fixed to a machine frame is connected via a bracket 5 to the outside of the skew guide 2 by the operation of the air cylinder 5.
By reciprocating b in a predetermined range along its longitudinal direction, the bottle container B is prevented from being caught between the skew guides 2a and 2b to cause bottle clogging.

However, in this conventional article alignment apparatus, the two rows of bottle containers B conveyed by the conveyor belts V1 'and V2' are skewed in the conveying direction of the belt conveyor by the skew guides 2a and 2b. The bottle containers B are squeezed from the width of the two bottles while being urged in the direction from the belt conveyor V1 'to the conveyor V3' side, and are arranged in a single row.
There is a problem that bottle clogging is likely to occur during narrowing.

The problem of bottle clogging when reducing the number of rows of conveyed goods conveyed by such a belt conveyor is not limited to the case where bottle containers are aligned, but also occurs in cylindrical containers such as canned products and cosmetics. Also occurs when reducing the number of rows of products.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the conventional article aligning apparatus.

That is, the present invention reduces the number of rows in a plurality of rows by a belt conveyor without causing clogging when changing the transport mode of the transported articles in a plurality of rows in accordance with each production process. An object of the present invention is to provide a device for aligning conveyed articles, which can easily eliminate the jam when conveyed articles are clogged. Another object of the present invention is to provide a transported article aligning apparatus which does not have a risk of damaging the transported article when aligning the transported article.

[0013]

In order to achieve the above object, a conveyor article alignment apparatus according to a first aspect of the present invention reduces the number of rows of a group of articles transported on a conveyor and conveyed in a plurality of rows. In a conveyor alignment device for aligning the required number of rows, a pair of staggered arrangement guide members arranged on both sides of the conveyor and a rotation axis that is perpendicular to the conveyance surface of the conveyor are rotatable. And a roller member having an outer peripheral portion protruded from at least one guide surface of the pair of staggered array portion guide members into the conveying path of the conveyor, and an upstream end portion of the pair of staggered array portion guide members. Is set to be equal to or larger than the width of the plurality of rows of the conveyed article group, and the interval of the downstream end is smaller than the width of the plurality of rows of the conveyed article group to be conveyed, and Aligned The staggered array portion is set to be larger than the required number of columns, and the staggered array portion is disposed downstream of a pair of staggered array portion guide members of the staggered array portion. It has a pair of narrowed portion guide members into which the group is carried in, and the interval between the upstream end portions of the pair of narrowed portion guide members is set to be substantially the same as the interval between the downstream end portions of the staggered array portion guide member and the downstream side. A narrowing section set so that the interval between the ends is substantially equal to the width of the required number of rows of the articles to be aligned.

In the conveyor conveyor aligning apparatus according to the first aspect of the invention, when a group of articles arranged in a plurality of rows is placed on a conveyor and conveyed to a staggered array section, the conveyed article group is moved to the staggered array section. When passing through, the distance between the pair of staggered array portion guide members of the staggered array portion becomes narrower toward the downstream side, so that the transported material in each row is transported to the adjacent row as the travel proceeds. It cuts between things.

[0015] When the conveyed object group reaches the mounting position of the roller member provided so as to protrude from the guide surface of the staggered array portion guide member into the conveying path of the conveyor, the conveyed object is moved to the outer peripheral surface of the roller member. The roller is moved while rotating the roller member about a rotation axis of the roller member in a plane parallel to the conveying surface of the conveyor. Since the objects are urged and width-shifted, the conveyed articles bite without being clogged between the conveyed articles in the adjacent row, and are formed in a staggered arrangement.

The group of articles arranged in a staggered manner in this manner is smaller than the width of a plurality of rows of articles conveyed to the staggered array section and smaller than the width of a required number of rows to be aligned. Is also carried out from between the downstream ends of the pair of staggered arrangement portion guide members set to be large, and is carried into the narrowing portion arranged downstream thereof.

[0017] The group of conveyed articles arranged in a staggered manner is narrowed at the downstream end so as to be substantially the same as the width of the required number of rows of the conveyed articles while passing through the narrowing section. With the movement of the pair of narrowing portion guide members, the narrowed portion is narrowed down along with the movement, the conveyed articles are arranged in a required number of rows, and are carried out from the narrowing portion.

As described above, according to the apparatus for aligning conveyed articles according to the first aspect of the present invention, conveyed articles conveyed in a plurality of rows are narrowed down, the number of rows is reduced, and the required number of rows is reduced. When aligning, the conveyed objects are arranged in a staggered manner in the staggered arrangement section before the plurality of rows of conveyed object groups are carried into the narrowing section, so that the conveyed articles are arranged in the narrowing section in a direction perpendicular to the transport direction. There is no danger of clogging by being sandwiched between the pair of narrowing portion guide members in the squeezed state. In the staggered arrangement portion, the conveyed articles can be arranged in a staggered manner easily and without causing clogging by being shifted in width by the roller member. In addition, when the conveyed article is shifted by the roller member, the roller member rotates following the movement of the conveying member and there is no relative movement between the two, so that they do not rub against each other. There is no risk of damaging the outer surface of the conveyed object such as abrasion.

According to a second aspect of the present invention, in order to achieve the above object, in addition to the configuration of the first aspect, the conveyors in the staggered arrangement section are arranged in parallel with each other. Side has a plurality of conveyor belts that are driven to increase the transport speed from one side to the other side, and the staggered array portion disposed on the side of the conveyor belt having the slower transport speed among the pair of staggered array portion guide members. The guide member is characterized in that its downstream end is inclined in a direction approaching the conveyor belt side where the conveying speed is high.

According to the second invention, in addition to the functions and effects of the first invention, in the group of articles conveyed into the staggered arrangement section, the articles in each row are placed on a conveyor having a different conveying speed. When the conveyed articles are transferred to the conveyer in the staggered arrangement section, the interval between the conveyed articles transferred to the fast-conveying conveyor is changed by the conveyed articles transferred to the slow-conveying conveyor. It is wider than the interval. Then, the conveyed material transferred to the conveyor having the slower conveying speed is arranged on the side of the conveyor belt having the lower conveying speed, and the staggered arrangement in which the downstream end is inclined in the direction approaching the conveyor belt having the higher conveying speed. The guides are pushed in the direction of the conveyor with the fastest transfer speed, and cut into the spaced objects on the conveyor with the fastest transfer speed, thereby forming the items in a staggered arrangement. It is being done.

According to a third aspect of the present invention, in the first aspect of the present invention, the two rows of staggered arrays are provided such that the interval between the upstream ends of the pair of staggered array section guide members is conveyed. Set so that it is equal to or larger than the width of the conveyed product group, and the interval between the downstream ends is set to be smaller than the width of the two rows of conveyed product groups to be conveyed and larger than the width of one row. The distance between the downstream end portions of the pair of narrowing portion guide members of the narrowing portion is set to be substantially equal to the width of one row of the conveyed object.

In the conveyor article aligning apparatus according to the third aspect of the present invention, the articles conveyed in two rows are arranged in a staggered manner in the staggered arrangement section, and then narrowed down in the narrowing section to be aligned in a single row. . According to the third aspect, since the two rows of articles are arranged in a zigzag before being narrowed down in order to align the articles in a single row, there is no possibility that the narrowed portion may be clogged. In the staggered arrangement section, the conveying member is shaken by the vibrating member and is further shifted by the roller member, so that a staggered arrangement is easily formed without clogging.

According to a fourth aspect of the present invention, in order to achieve the above object, in addition to the configuration of the first aspect, at least one of the pair of staggered array portion guide members of the staggered array portion is provided. A vibrating member attached to the staggered array section guide member to vibrate the staggered array section; a first transported article detection member attached to the staggered array section to detect a transported article transported through the staggered array section; A second article detection member attached to the side conveyance path and detecting the article conveyed through the conveyance path; and a second article detection member connected to the vibration member, the first article detection member, and the second article detection member. 1
A control member that outputs an operation signal to the vibration member to drive the vibration member when the detection signal of the conveyance object is input from the conveyance object detection member and the detection signal of the conveyance object is not input from the second conveyance object detection member for a predetermined time; It is characterized by having.

In the apparatus for aligning conveyed articles according to the fourth aspect of the present invention, the conveyed articles conveyed in the staggered arrangement portion are detected by the first conveyed article detecting member, and the detection signal is output to the control member. In addition, a conveyed object conveyed on the conveyance path downstream of the narrowing unit is detected by the second conveyed object detection member, and a detection signal is output to the control member. When the detection signal is not input from the second conveyance detection member for a predetermined time or more while the detection signal is input to the control member from the first conveyance detection member, the control member outputs an operation signal to the vibration member. Then, this vibration member is operated.

According to the apparatus for aligning conveyed articles of the conveyor according to the fourth aspect of the present invention, the control member is provided with the second conveyed article detecting member despite the fact that the detection signal is inputted to the control member from the first conveyed article detecting member. When the detection signal is not input for a predetermined time or more from the above, it is possible to determine that the conveyed object is clogged in the staggered array section, and based on this determination, the staggered array section guide member of the staggered array section is vibrated. This can eliminate the clogging of the conveyed object.

An operation signal is output to the controller.

Next, the operation of the apparatus for aligning conveyed articles on the conveyor will be described.

The four rows of bottle containers B, which are placed on the conveyor belt V1 and conveyed while being guided by the parallel guide section 10, are sorted into two rows of bottle containers B, while being guided by the sorting guide section 11. It is carried into the staggered arrangement section S. At this time, the two rows of bottle containers B are transferred from the conveyor belt V1 onto the conveyor belts V2 and V3.

The bottle container B carried into the staggered arrangement section S
Since the driving speed of the conveyor belt V3 is higher than the driving speed of the conveyor belt V2, the bottle containers B of the outer bottle row transferred onto the conveyor belt V3 out of the two rows of bottle containers B are By moving faster than the bottle containers B of the inner bottle row transferred on the conveyor belt V2, and furthermore, the interval between the staggered array parallel guide 12A and the staggered array skew guide 12B gradually narrows, The bottle containers B arranged in two rows enter between adjacent rows and are arranged in a staggered manner.

When the bottle container B on the conveyor belt V3 reaches the position where the bottle applying roller 14 is mounted, the bottle container B comes into contact with the outer peripheral surface of the bottle applying roller 14 projecting on the conveying path of the conveyor belt V3. Contact conveyor belt V3
Of the bottle contact roller 14 with its rotation shaft 14A
While rotating around the conveyor belt V2
, The bottle container B on the conveyor belt V3 smoothly penetrates between the bottle containers B on the conveyor belt V2. In this way, bottle container B
They are arranged in a staggered pattern.

Then, the bottle container B and the bottle applying roller 14 are not rubbed with each other because the bottle applying roller 14 rotates following the movement of the bottle container B and there is no relative movement between them. For this reason, there is no possibility of causing damage such as abrasion on the outer peripheral surface of the bottle container B.

As described above, the bottle rows of the bottle containers B arranged in a staggered manner in the staggered arrangement section S are carried into the narrowing section T.

In the narrowing-down section T, the bottle containers B arranged in a staggered arrangement are connected to the conveyor belts V2 and V3.
While being advanced by the conveying force, the inclined guides 18B are brought closer to the conveyor belt V4 by the inclination of the inclined guides 18B, and furthermore, the distance between the inclined guides 18A and 18B is narrowed, so that they are aligned in a single row.

Then, between the downstream ends of the inclined guides 18A and 18B, the bottle containers B completely aligned in a single row
Is transferred from the conveyor belt V3 onto the conveyor belt V4, is conveyed while being guided on both sides by the pair of single-row parallel guides 19A and 19B by the conveyor belt V4, and is carried into the next production process. .

Here, the bottle container B passing through the sorting guide portion 11 is detected by the limit switch 20 when the bottle container B comes into contact with the contact 20A, and the limit switch 20 outputs the detection signal of the bottle container B. Output to the control unit 40. The optical sensor 30 is a single-row parallel guide 19.
A bottle container B passing between A and 19B is detected, and a detection signal is output to the control unit 40.

Then, the limit switch 2 is
In the state where the detection signal is input from 0, the optical sensor 30
When the detection signal is not input for more than a preset time, the control unit 40 outputs an operation signal to the vibrator 13 to operate the vibrator 13.

In the state where the detection signal is input from the limit switch 20 to the control unit 40 and the detection signal is not input from the optical sensor 30 for a predetermined time, the bottle container B passes through the sorting guide unit 11. Nevertheless, this shows a state in which the bottle container B does not flow between the single-row parallel guides 19A and 19B, that is, a state in which the bottle is clogged in the staggered arrangement section S. Based on the detection signal from the optical sensor 30 and the input state of the detection signal from the optical sensor 30, the occurrence of a bottle jam is determined, and an operation signal is output to the vibrator 13.

The set time for the control unit 40 to measure the time during which the detection signal is not input from the optical sensor 30 to determine whether or not bottle clogging has occurred is determined when the bottle container B is in the staggered arrangement unit. The length is set to be longer than the time required to move from S to the mounting position of the optical sensor 30.

When the bottle is clogged in the staggered arrangement section S and the operation is outputted from the control section 40 to the vibrator 13,
The vibrator 13 starts driving to vibrate the staggered array portion parallel guide 12A. This staggered array part parallel guide 12
The bottle row in the staggered arrangement section S is shaken by the vibration of A, thereby eliminating bottle clogging.

Then, the bottle clogging is eliminated and the bottle B starts to flow between the single-row parallel guides 19A and 19B.
Is detected by the optical sensor 30 and the detection signal is input to the control unit 40, the control unit 40
Stops outputting the operation signal to.

In the above example, the conveyor belt V1
The bottle containers B conveyed in four rows are distributed to the distribution guide sections 11 and 11 'to form two rows of bottles, and then are carried into the staggered arrangement section S. It goes without saying that even when the conveyor belts V2 and V3 are conveyed in two rows, they can be similarly arranged in a single row.

In the above example, the vibrator 13 and the bottle applying roller 14 are attached to only one of the guides in the staggered arrangement S. However, the vibrator or the bottle applying roller may be attached to both the guides. Thus, it is possible to prevent jamming when aligning the articles transported by the conveyor more completely.

In the above description, an example in which two rows of bottle containers are arranged in a single row has been described. However, the present invention is not limited to the above example, and the number of bottle rows of two or more rows may be reduced. The present invention can be applied to a case where a smaller number of rows are arranged, and also to a case where cylindrical containers such as canned products and cosmetics are arranged in addition to bottle containers.
