2. Description of the Related Art In a conventional article collecting technique of this kind, a guide member is arranged on a plurality of transport conveyors arranged in parallel and adjacent to each other so as to obliquely cross the transport conveyors. By setting the transport speeds of the downstream transport conveyors adjacent to each other to be relatively high, a technique of collecting a plurality of rows of articles introduced on the transport conveyor into one row along the guide member is known. This is known (JP-A-63-47223).
Further, a suction hole is formed in the transfer surface of the transfer conveyor, and the suction hole is communicated with a wide and narrow slot having a different opening width formed in the upper surface of the vacuum chamber, so that the article can be moved by the guide member and the suction force. A technique of assembling in columns is known (Japanese Patent Publication No. 3-55373). That is, a plurality of articles are supplied obliquely arranged in advance in the introduction section to the collective work area, and among them, a slot having a narrow opening width is opposed to a conveying line for articles going backward, and a weak suction force is applied. And a slot having a large opening width is opposed to the vicinity of the guide member with respect to the conveyance line of the front article, so that the front member is held along the conveyance line while holding the front article with a strong suction force. There is known an assembling technique in which articles are regularly conveyed so as to assemble in a line along a guide member while pressing a front end of a rear article.

According to the former prior art, a plurality of containers are guided to a collecting device as they are at random, so that a large number of containers are guided by a guide member and a relative change in the transport speed of a transport conveyor adjacent to each other. It is excellent in that it can be smoothly gathered in one line by the cooperation of
Because it is the one that assembles while simply transporting on a transport conveyor, when applied to a container that is not lightweight and has a relatively high center of gravity and a relatively poor self-standing stability, such as an empty PET bottle,
There was a drawback that the fall easily caused trouble. In addition, the latter conventional technique requires an alignment mechanism for adjusting the state of introduction of the articles into the collective work area, and is suitable for a case where a large number of articles are to be simultaneously assembled based on the above-described assembly principle. Did not. Furthermore, since the front articles are held by a strong suction force to hold the other rear articles while holding them together, and after the essential gathering, the suction force is weakened, the self-sustaining stability is not good like an empty PET bottle. In the case of assembling containers, there has been a drawback that the fall easily causes trouble.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a plurality of conveyors arranged in parallel and adjacent to each other, and is disposed so as to obliquely cross the conveyors. A guide member for guiding a plurality of rows of articles to be introduced on the transport conveyor into one row is provided, and the transport speed of the downstream transport conveyor is set to be relatively high, and the transport surface of each transport conveyor is provided. A suction unit communicating with the vacuum chamber is formed, and a suction force acting through the suction unit is set so as to be relatively large on the downstream side. In the upstream area, the suction force is reduced to suppress the restraining force on the articles, thereby facilitating the collection of the articles along the guide member, and the frequency of the relative movement between the articles is reduced as the collection proceeds. In the area of fast transport speed downstream employs the technical means to suppress a fall by increasing the restraining force against the article by increasing relatively the suction force.

Means for setting the suction force acting via the suction section to be relatively large on the downstream side include, for example, a vacuum provided below the transport conveyors arranged in parallel and adjacent to each other. By forming a chamber and connecting a vacuum device such as a blower to the downstream side of the vacuum chamber itself, the suction force on the downstream side can be set relatively large depending on the distance to the connection portion, or the vacuum chamber can be transported. By forming a plurality of compartments by partitioning in the direction and sequentially setting the internal pressure of those compartments to be lower toward the downstream side, the suction force on the downstream side may be configured to increase relatively. It is possible. When the vacuum chamber is partitioned into a plurality of compartments, it can be partitioned into three or more compartments according to the introduction area, the collection area, the discharge area, and the like. In addition, if a gap is formed above the partition plate that divides the vacuum chamber into a plurality of compartments to allow air to flow between the compartments, the change in suction force near the partitions is gently improved. can do. Further, by arranging an air guide that opposes the guide member and that blows out air toward the guide member, the collective action of the articles can be assisted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is suitable for assembling containers such as empty PET bottles which are not lightweight and have a relatively high center of gravity and a poor self-standing stability. Needless to say, the method can be applied favorably. There is no particular restriction on the mode of introducing the articles into the collective work area, and it is possible to cope with the case where the articles are introduced in a random state consisting of multiple rows. The width and the number of the conveyors arranged in parallel are set in consideration of the type and processing amount of the target article, that is, the introduction amount of the article into the collective work area. In addition, regarding the transport speed of each transport conveyor, taking into account the processing amount of the article, the possibility of the article falling over, the cooperative action with the guide member, etc., a smooth collective action is obtained as a whole. The setting is made such that the transport speed of the downstream transport conveyor is relatively increased.
In that case, the speed ratio between the adjacent conveyors may be uniformly determined for the entire conveyor, but may be changed. Further, a configuration may be adopted in which a plurality of transport conveyors are grouped at the same speed and a speed difference is provided between adjacent transport conveyors. Further, it is also possible to set so that the conveying conveyor in the area to be delivered to the discharge conveyor after the collective operation is almost completed is decelerated according to the transfer speed of the discharge conveyor. In short, the conveying speed of the downstream conveyor is set to be relatively high in the collective work area where the articles are collected from a plurality of rows, and a good collecting action is obtained by the difference in the conveying speed. Anything should do.

A preferred example of the suction section formed on the transfer surface of the transfer conveyor in communication with the vacuum chamber is a form in which a suction hole is formed in a slat portion or the like constituting the transfer surface, but is not limited thereto. It is not necessary, and it is possible to form a suction gap between the slats. The size and shape of the opening area as the suction part are determined in consideration of the self-standing stability of the article and the pressure of the vacuum chamber, that is, the negative pressure state, and the stability of the article in the collective work and the relative distance between the articles accompanying the gathering. It is set as appropriate to suit the possibility of target movement. In this case, the form uniformly determined for all the conveyors is simple, but the suction force on the downstream side is increased by forming the opening area of the suction portion of the downstream conveyor relatively large. It is also possible to set.

A vacuum chamber is formed below the conveyors arranged in parallel and adjacent to each other. By connecting to a vacuum device such as a blower through the downstream side of the vacuum chamber itself, the suction force on the downstream side can be set relatively large depending on the distance from the connection position. In addition, the vacuum chamber is partitioned in the transport direction to form a plurality of compartments, and the internal pressure of these compartments is sequentially controlled to be lower toward the downstream side so that the suction force on the downstream side is relatively increased. Can also be set to In that case, it may be divided into three compartments according to the introduction area, the collection area and the discharge area, or may be divided into three or more compartments according to the length and the processing amount of the apparatus. In short, in the upstream region where the frequency of relative movement between articles is relatively high and the transport speed is relatively low, which corresponds to the initial stage of the work, the suction force is reduced to suppress the binding force on the articles, While providing a state that is easy to assemble along the guide member, corresponds to the middle or late stage of more advanced assembly work, in the downstream region where the frequency of relative movement between articles is low and the transport speed is relatively fast, Any device may be used as long as the suction force is relatively increased to increase the restraining force on the article so as to prevent the article from overturning. The specific value of the suction force is related to the level of the overall transport speed of each transport conveyor. In other words, in an apparatus in which the transport speed is set to be slow overall, the suction force is set to be relatively small, and the relative suction force between the respective conveyors is adjusted in the apparatus. Become. Further, in the case of a device in which the transport speed is set to be generally high, the overall speed is set to be relatively large, and the relative suction force between the respective transport conveyors is adjusted in the apparatus. Further, as described above, when the vacuum chamber is partitioned into a plurality of compartments, if a gap is formed above the partition plate to allow air to flow, a change in suction force in the vicinity of the partition portion is obtained. Can be improved to be more gradual. In addition, by arranging an air guide facing the guide member and ejecting air toward the guide member, it is possible to assist the collective action of the articles.

When the articles 5 composed of a plurality of rows are randomly introduced from the introduction section 4, at an initial stage of the upstream assembly work, the guide member 3 is partially moved as shown in FIG. While the articles 5 serve as a barrier and collect in a dumpling state, relative movement between the articles is frequently performed by the cooperative action of the guiding action of the guide member 3 and the relative speed difference between the respective conveyors 2, Collecting work of the articles 5 is performed along the guide member 3. That is, here, due to the relative speed difference between the respective transport conveyors, the containers 5 on the downstream transport conveyor pass along the guide members 3 overtaking the front containers 5 on the upstream transport conveyor. And the collection is performed sequentially. In that case,
As described above, the negative pressure in the upstream compartment 15 is not so large, and the suction force acting on the article 5 through the suction holes 20 formed in each slat 19 of each transport conveyor 2 is suppressed to a small value. Since there is little hindrance to the relative movement between the articles, a state is provided in which the articles can be easily assembled along the guide member 3. Moreover, in this upstream area,
Since the transport speed of the transport conveyor 2 is not so high, even if the suction force is kept small, it is enough to prevent the articles 5 from falling.

[0014] Then, the assembly work proceeds by moving the article 5 to the downstream side, and in the middle or late stage, the frequency of relative movement between the articles gradually decreases, and conversely, the transport speed of the transport conveyor 2 decreases. Be faster. In the present embodiment, as described above, the negative pressure of each of the compartments 16 to 18 is set to increase as going to the downstream side, so the suction force acting on the article 5 through the suction hole 20 is Increase gradually. Therefore, the suction force is increased as the transport speed of the article 5 is increased and becomes unstable, so that the article 5 is efficiently prevented from falling. In addition, as described above, the suction force is increased toward the downstream side, and the restraining force on the articles 5 is gradually increased. However, the relative movement between the articles due to the collective action is also gradually reduced. It is possible to configure so as not to cause any particular trouble in the collective action.

As described above, the present invention relates to the conveyor 2
When the collective action of the articles 5 is performed along the guide member 3 while increasing the transport speed relatively as the transport speed advances toward the downstream side, the frequency of the relative movement between the articles due to the collective action in the upstream area Paying attention to the fact that while the transport speed is large and the transport speed increases toward the downstream side, the frequency of the relative movement between the articles accompanying the collective action decreases, and the transport speed of the article 5 is reduced. In addition, in accordance with a change in the frequency of the relative movement, the suction force on the article 5 is increased as it goes downstream. In other words, the conveying speed is small and the possibility of falling is small, and the suction force is suppressed on the upstream side where relative movement between the articles is required. On the contrary, the conveying speed is large and the possibility of the article 5 falling is large. The suction force is set to gradually increase while balancing the change in the transport speed of the article 5 and the frequency of the relative movement so that a good collective action can be obtained in the entire area up to the downstream side where the target movement is small. Will do.
