Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for assembling a partition wall for aligning and receiving articles to be packed in a packing space such as a packing member.
[0002]
[Prior art]
For example, when packing a vertically long article such as a glass bottle, the space of a packing member such as a cardboard box is divided into a size suitable for the article to be packed, and the article is accommodated in each of the divided spaces. Thus, a plurality of articles are stably accommodated in one packaging member without contacting each other. As a member for partitioning such a packing space, for example, a partition wall is used in which cardboard paper is appropriately cut and combined vertically and horizontally.
[0003]
[Problems to be solved by the invention]
However, the assembly of the partition walls as described above is often performed manually, and there is a problem that the burden on the operator is large or the work efficiency is poor. Even if an apparatus that automates assembly work is used, depending on the type of articles to be packed, the quantity to be packed at one time may be small, and thus a simple and compact apparatus is desired.
[0004]
The present invention has been made in view of these points, and an object of the present invention is to provide a means for automating the assembly of the partition wall in a simple and space-saving manner.
[0005]
[Means for Solving the Problems]
Partition wall assembly apparatus according to claim 1 of the present invention made in order to achieve the above object, the both sides to each of the plurality of partition under plate notches are formed symmetrically and holds the stacked, one partition A partition lower plate supply mechanism that feeds the lower plate in a substantially horizontal direction, a partition lower plate bending mechanism that bends both sides of the supplied partition lower plate upward, and a notch in each of the folded partition lower plates. A partition lower plate feeding mechanism that intermittently moves the partition lower plate so as to be positioned at the insertion position of the partition upper plate, and a partition upper plate having a cut formed at the lower end to engage with the notch of the partition lower plate, A partition upper plate holding mechanism that holds the notch aligned in a substantially upright position at a position engageable with a notch of the folded partition lower plate, and one partition upper plate held by the partition upper plate holding mechanism To send down Ri, comprising a partition upper insertion mechanism for engaging the the partition top plate into the notches of the partition lower plate which are brought position the insertion position, the, by the partition plate differential write mechanism, is intermittently transported The partition upper plate is sequentially engaged with each notch of the partition lower plate .
[0006]
The partition lower plate and the partition upper plate are rigid enough to maintain a certain shape and can be bent, and corrugated paper or cardboard is preferable. The notches in the partition lower plate are formed from both sides toward the center, but may be formed in a desired number and position symmetrically in consideration of how to partition the packing space. Further, the folding position at which both side portions of the partition lower plate are folded is also set as appropriate in consideration of the way of partitioning the packing space. On the other hand, the notches in the upper partition plate are engaged with the incisions on both sides of the folded lower partition plate, and therefore are formed at two locations according to the folding position of the lower partition plate. For example, in the case of dividing the packing space into nine equal spaces, two pairs of cuts are formed at the position where the side edge of the partition lower plate is divided into three equal parts, and the dimensions of the three equal side edges and the partition The folding position is set so that the center portion of the lower plate, that is, the width of the bottom portion when the both side portions of the partition lower plate are bent, has substantially the same dimension. The entire width of the upper partition plate is approximately the same as the entire width of the side edge of the lower partition plate, and two cuts are formed in accordance with the folding position of the lower partition plate, that is, at a position that divides the total width into three equal parts. By combining two partition upper plates with one partition lower plate, it is possible to obtain a partition wall that divides the packing space into three equal parts of 3 × 3.
[0007]
The partition lower plate bending mechanism includes a pressing member that presses a substantially central portion from above the partition lower plate along the bending position, and a pair of push-up members that pushes the right side of the bending position from below the partition lower plate. It is preferable that it is provided with these. Thereby, it is possible to accurately bend the side portion from the folding position.
[0008]
Moreover, it is preferable that the contact part with the partition lower board of the said raising member has a gradient shape which descend | falls toward a bending position. As a result, the push-up member in the part far from the folding position comes into contact with the partition lower plate and pushes up both sides thereof, making it easy to start folding and then pushing up near the folding position. When the members come into contact with each other and push up the both side portions, the both side portions can be reliably erected in the substantially vertical direction from the bending position.
[0009]
It is preferable that the partition upper plate holding mechanism is configured to hold the partition upper plate in a slope shape so that the partition upper plate to be delivered is at the lowermost end. In order to send the partition upper plates aligned and held in the substantially upright state sequentially downward from the predetermined position, the aligned upper partition groups after the one partition upper plate is sent are sequentially moved toward the predetermined position. However, by aligning and holding the partition upper plate in a slope shape, the aligned upper partition group after the one partition upper plate is sent out slides down to a predetermined position by its own weight. . Accordingly, there is no need to provide means for moving the partition upper plate group toward a predetermined position, such as urging the partition upper plate group by a spring or an air cylinder, and the partition upper plate holding mechanism is realized with a simple configuration. It becomes possible.

Thereafter, the lower partition plate 1 is conveyed again by the lower partition plate feed conveyor 30 until the next cut 1a is located at the insertion position P. Next, after the cut 1a is positioned at the insertion position P, the partition lower plate feed conveyor 30 is stopped again, and the partition upper plate insertion mechanism 105 is operated in the same manner as described above, so that the insertion plate 50 is moved to the partition upper plate. The lower partition upper plate 2 of the stock unit 104 is sent downward. Thereby, the notch 2a of the partition upper plate 2 is engaged with the next notch 1a of the partition lower plate 1, and the second partition upper plate 2 is combined with the partition lower plate 1. In addition, the partition upper plate 2 group remaining in the partition upper plate stock unit 104 also slides to the lowermost end side by its own weight as described above, and the lowermost partition upper plate 2 is sucked and held.
[0031]
Further, as described above, after the partition lower plate 1 is conveyed by the partition lower plate feed conveyor 30 until the last notch 1a is located at the insertion position P, the insertion plate 50 is moved to the lowermost end of the partition upper plate stock unit 104. The upper partition plate 2 is fed downward, and the third partition upper plate 2 is combined with the lower partition plate 1. In this manner, the partition lower plate 1 and the three partition upper plates 2 are combined to form the partition wall 3.
[0032]
Although not shown in the figure, a conveyor or the like for transporting a packing member such as a cardboard to which the partition wall 3 should be inserted is installed below the partition lower plate feed conveyor 30, and a robot arm or the like is used to It is also possible to adopt a configuration in which the partition wall 3 combined by the partition wall assembling apparatus 100 is inserted into the packing member.
[0033]
