Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a special method for packaging articles of a predetermined outer diameter, such as bottles.

Conventionally, when packaging items such as bottles sent on a conveyor, the bottles are arranged in a predetermined row at a predetermined equal pitch at a grip station, and then
A packaging method is adopted in which the materials are loaded as they are into each section of a box having a predetermined pitch and a predetermined number of rows.

However, recently in the packaging industry for goods (bottles),
For example, there has been a trend toward the use of boxes with special compartments as shown in FIG. 1, that is, boxes with special compartments such that the pitch between the article storage compartments in each row is not necessarily constant.

However, a method for orderly packing articles (bottles) sent by an incoming conveyor into boxes having special compartments as described above has not been realized to date. In view of the above-mentioned circumstances, the present invention has been proposed for the purpose of providing a method for automatically packing articles into boxes partitioned in, for example, a staggered pattern as described above. In this case, the bottom surfaces of the articles being conveyed in a sequentially aligned state are separated from each other by the heads of the articles.
A predetermined number of these parts are placed on the inclined surface of an article moving table which has an inclined surface that is appropriately inclined in the front-rear and left-right directions so as to have an almost staggered shape when viewed from above, and a predetermined number of these parts are placed on the article moving table.
At the same time as the step of placing the article out of place, the article placed on the article moving table is transferred to a position directly below the gripper together with the article moving table, and the inclined surface of the article moving table is used to transfer the article to a position directly below the gripper.
A step of tilting the articles in the front-rear and left-right directions so that the heads thereof are spaced apart from each other and exhibiting a substantially zigzag shape when viewed from above; , with the above grippers arranged in an almost staggered pattern,
Grasping the head of the article, then retracting the article moving table from the position, and lowering the gripper to the boxing position of the article, so that each section of the box is partitioned into a staggered arrangement by a partition plate. The present invention relates to a method for packaging articles, which comprises the steps of loading the articles into the container, releasing the grip of the gripper, and packing the articles into the box.

Bottle d shown in Figure 6a
When the bottle d is gripped by the gripper 56 and raised by the return operation of the cylinder 58, the bottle d is tilted toward the bottle b by the rail 32 at the grip position (m<n), so the lower part of the body of the bottle d is constrained by the bottle guide 29. As the bottle 200 climbs onto the notch 61, the constraints of the bottle guide 29 are gradually reduced, and as the bottle 200 disengages from the bottle guide 29 and hangs freely, the relative position of the bottle 200 is determined as shown in FIG. It becomes as shown in . The cylinder 38 is actuated by means not shown, and the movable table 34 moves forward while being regulated by the lever 36, rod 37, etc., to a position where it does not interfere with the bottle 200 held by the grip when the bottle 200 is lowered. The two-stage cylinder 5 is raised by a means not shown, and stops at the casing position with the tip 49 placed inside the case 201.
When the second stage 8 is operated, the grip head 2 and the gripper 56 are lowered, and the gripped bottle 200 is guided by the bottle positioning plate 62 and the nozzle 49 and inserted into the case 201. The bottle 200 is released from the gripper 56 by means not shown and is housed in the case 201 as shown in FIG. The planar positional relationship between the bottle 200 gripped by the gripper 56 and the case 201 is as shown in FIG. 9. The gripped bottle 200 is guided by the tip 49 and descends.
Even though the grip rubber 56a is at a position where it interferes with the case 201 in plan view, the grip rubber 56a is bent and the seventh
It goes into place as shown in the figure. The case lift 5 is lowered by means not shown and sent to a case conveyor not shown. Next, the grip head 2, moving table 34, bottle holder 44, sensing frame 44b1, lever 24, etc. are returned to their original positions by means not shown, and the next cycle begins. In summary, the present invention provides a means for separating the bottom surfaces of the articles that are sequentially conveyed in an aligned state by the conveyor so that the heads of the articles are spaced apart from each other.
A predetermined number of articles are placed in a predetermined row on the article moving table by placing the articles on the inclined surface of the article moving table which has an inclined surface suitably inclined in the front-rear and left-right directions so as to have an approximately staggered shape when viewed from above. In the same step, the articles placed on the article moving table are transferred together with the article moving table to a position directly below the gripper, and the inclined surface of the article moving table is used to move the articles onto the top of the article moving table. a step of tilting in the front-rear and left-right directions so that they are spaced apart from each other and exhibiting an approximately staggered shape when viewed from above; Grasping the head of the article with the gripper, then retracting the article moving table from the position, and lowering the gripper to the boxing position of the article, where the boxes are partitioned in a staggered arrangement by partition plates. The gist of this article is a method for packaging articles, which is characterized by the step of loading the articles into each compartment, releasing the grip of the gripper, and packing the articles into the box. According to the invention, a practical effect can be achieved in that it is possible to realize a packaging method that can meet the demands of the recent packaging industry. As in the case of the above embodiment, after the bottle 200 is gripped by the first stage of the two-stage cylinder 58, it is held as it is without returning to the original position, and the moving table y is lowered along the cam 59. In this case, the bottle positioning plate 62 or the like serves as a steady rest for the bottle 200.
