Description

  The present invention relates to a container alignment transport device that aligns a number of containers such as bottles that are upright in a non-aligned state while being transported by a conveyor belt of a belt conveyor system, and more particularly, while preventing containers from falling over, The present invention relates to a container aligning and conveying apparatus that can also prevent clogging (hereinafter referred to as a bridge).

  When using a conveyor device of a belt conveyor system to align a plurality of cylindrical containers such as bottles in a single row from a plurality of unaligned states, bridging between containers and falling bottles occur at the relevant part of the conveyance path, There arises a problem that the transfer process is frequently interrupted. As means for solving such a problem, for example, an apparatus of Patent Document 1 has been proposed. However, in Patent Document 1, when forming the bridge of the container, the bridge is to be eliminated by a method of widening / returning the traveling width of the conveyance path formed by a pair of guides provided with guide rollers. When the guide reciprocates on the conveyance path, a gap is generated between the containers, and there is a problem that a fall bottle is likely to be generated in a container that has lost balance due to contact between the containers.

In order to transport the cylindrical container, it is common to bring a wide guide roller into contact with the largest diameter part of the cylindrical container. In particular, when transporting containers having different outer diameters depending on the part, the contact part between the guide roller and the container is small in the transport direction, which causes a problem that the transport state of the container becomes unstable and the bottle tends to fall over.

  According to the present invention, in a container aligning and conveying apparatus such as a bottle, bridge formation between containers can be eliminated with a simple configuration without the need for a power source such as a further power source or compressed air, and Can be prevented.

  Hereinafter, a container aligning and conveying apparatus of the present invention will be described with reference to the drawings.

  FIG. 1 is a plan view of a container aligning / conveying apparatus that conveys a number of unaligned containers 1 while aligning them using a roller guide type container aligning / conveying apparatus according to the present invention. FIG. 2 is an elevational view showing a state when the container is being conveyed in the vicinity of the swing guide 3 and the fixed guide 4 in FIG. FIG. 3 is a schematic cross-sectional view of a roller according to the present invention.

  In FIG. 1, a large number of unconsolidated containers 1 placed on the conveyor belt 2 of the belt conveyor and carried in the direction of the arrow indicated by X have a predetermined angle with respect to the traveling direction of the conveyor belt 2. A swingable swinging guide (guide A) 3 that narrows the container 1 along the flow to one side of the belt and a position of the conveyor belt 2 facing the swinging guide 3 is provided. A fixed guide provided so as to be in the same direction as the traveling direction, a so-called fixed guide (guide B) 4, is aligned in a single row while being conveyed. The containers 1 on the transport belt 2 aligned in a single row are then guided by the guides 5 and 6 and are carried out in the direction of the arrow indicated by Y.

  In general, in such a roller guide type container aligning and conveying apparatus, particularly in the vicinity of the transition from a large number of unaligned state to a single row aligned state, the flow of the assembled state of the containers 1 is pushed from the upstream and squeezed in the pressed state. There is a problem that bridge formation and falling bottles tend to occur, and the conveyance process is frequently interrupted. However, according to the present invention, this problem can be reduced.

  That is, in the apparatus of the present invention, as shown in FIG. 1, at least one of the pair of swing guides (guide A) 3 and fixed guide (guide B) 4 is parallel to the transport surface of the transport belt 2. Have a plurality of rollers 8a, 8b,... Rotatable in the surface (roller guide 8), and at least a part of the plurality of rollers 8a, 8b,. It arrange | positions so that it may overlap with the said cylindrical container in the projection surface.

  Specifically, it is shown in FIG. The assembled container 1 is conveyed by a belt 2 of a belt conveyor. When the container 1 shifts from the non-aligned state to the single-row aligned state, a plurality of rollers 8a, 8b,... Arranged in the swing guide (guide A) 3 and the fixed guide (guide B) 4 convey the container 1. Although the rollers 8a, 8b,... Are arranged so as to be rotatable in a plane parallel to the transport surface of the transport device, the containers 1 form a bridge. Even if it becomes a state, both of the container 1a that contacts the roller guide on the swing guide 3 side and the container 1b that contacts the roller guide 8 on the fixed guide 4 at the moment, or either one of the containers Upon receiving the pressing pressure, natural rotation and natural movement (escape) in the traveling direction or the counter-traveling direction can prevent the occurrence of a bridge. Further, since the rollers 8a, 8b,... Are arranged so as to overlap the container 1 on the projection surface onto the conveying belt 2, the container 8 having a shape whose outer diameter changes in the axial direction is conveyed. Even so, the container 1 can be supported not by dots or lines but by a surface, and the container 1 can be prevented from being overturned.

  Here, the shape of the rollers 8a, 8b... Is preferably smaller than the diameter of the portion where the roller of the container abuts, and further has a diameter of 20% to 40% of the diameter of the corresponding contacting portion, and is about 30%. Is particularly preferred. This is because when the container 1 is guided in contact with the roller guide 8 and the diameter of the roller is larger than the diameter of the contact portion of the container 1, a plurality of containers 1 may come into contact with one roller. This is because the degree of freedom when the roller rotates is lost, the resistance increases, and the effect on the bridge is reduced. Furthermore, when the diameter of the rollers 8a, 8b... Is larger than 40% of the diameter of the contact portion of the container 1, the distance between the rollers arranged next to each other increases, and the rollers cannot hold the container 1. When the container 1 is smaller than 20%, the contact surface with the outer peripheral surface of the container 1 is reduced and the effect on the falling bottle is reduced. It is to be done.

  Next, FIG. 3 shows an attachment configuration diagram of one roller. Each of the rollers 8a, 8b,... Is fitted to the shaft 9 so as to form a certain clearance so as to be rotatable around the axis, and the upper portion thereof is a bolt 10 or the like inserted into the shaft. The fitting part is fixed so as to prevent the withdrawal. The shaft 9 is fixed by being screwed into the base 11. As long as the shaft 9 is fixed, the shaft 9 does not need to be cylindrical, and may be linear. When the shape of the container to be transported is changed, it is possible to easily cope with it by loosening the bolt 10 and replacing the roller with a roller that matches the shape of the container after the change.

  In the present invention, the guide A for forming the predetermined angle with respect to the traveling direction of the conveyor belt and bringing the container closer does not need to be swingable. Gives movement and can greatly contribute to bridge elimination by escape between containers. Therefore, it is preferable that the guide A is a swinging guide as in the above-described aspect, and the guide provided so as to be opposed and in the same direction as the traveling direction of the transport belt is a fixed guide.

<Comparative Example 1>
In the container aligning and conveying apparatus in which the rollers 8a, 8b... In FIG. 1 are arranged so as to make point contact with the cylindrical container on the projection surface onto the conveying belt, the vials (body diameter φ23) are used for about one year. 1.0 mm, height 46.5 mm). The total number of vials transported was about 270,000.

<Example 1>
In the roller guide type container aligning and conveying apparatus of the present invention shown in FIG. 1, vials (body diameter φ23.0 mm, height 46.5 mm) were aligned and conveyed for about one year. The total number of vials transported was about 270,000.

  As a result of Comparative Example 1 and Example 1, in Example 1, the number of falling bottles was compared with 78 times / year of Comparative Example 1 to 16 times / year (reduction in incidence: 99.5%), and the number of occurrences of bridge was compared. It was improved from 297 times / year of Example 1 to 15 times / year (reduction of 94.9% of occurrence rate), and it was confirmed that it was possible to greatly contribute to productivity improvement by greatly improving work efficiency.

  Further, the apparatus of Comparative Example 1 is intended to eliminate the bridge only by a method of widening / returning the traveling width of the conveyance path composed of the swing guide and the fixed guide, and the guide reciprocates on the conveyance path. In the first embodiment, there is a problem that a gap is generated between the containers, and a fall bottle is likely to be generated in a container that has lost balance due to contact between the containers. Since the natural rotation and natural movement (escape) occur in the direction, it is basically difficult to generate a gap between the containers, and the container is difficult to fall over because it is assisted by the contact portion with the guide roller.

It is a schematic plan view of the roller guide type container alignment conveyance apparatus which shows one Embodiment of this invention. It is an enlarged elevation view which shows the contact state of the roller and container in the apparatus of this invention. It is an expansion section outline figure showing the composition of the roller in the device of the present invention.
