[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article supply control device for a cartoning machine.

[0002]

2. Description of the Related Art For example, a relatively large number of short columnar articles (hereinafter referred to as "can bodies"), such as cans and bottles, which are placed on a conveyor in a plurality of rows in the longitudinal direction and conveyed respectively.
As an article supply control device (hereinafter referred to as an article supply control device) for a box packing machine that sequentially sorts into a relatively small number of cans, conventionally, FIG. 4 (A) side view, FIG. 4 (B) plan view and FIG.
(C) A partially enlarged view is known. That is, in the figure, the article supply control device is provided in parallel with a conveyor 03 that conveys a large number of can bodies 01 placed in a row in the forward direction 02 and a little above the conveyor 03 along the forward direction 02. A plurality of transport guides 04 in the form of horizontal parallel bars for arranging a large number of can bodies 01 into a plurality of rows of a relatively large number of can bodies 01, and each of the above-mentioned relatively large number of can bodies 01 is a relatively small number of boxes It is composed of a finger plate insertion mechanism 05 that sorts the cans 01 in the packing number one by one. In the figure, the finger plate insertion mechanism 05 arranged below the conveyor 03 is
A pair of front and rear sprockets 06, 07, an endless chain 08 wound around the sprockets, a plurality of rectangular finger plates 09 projecting from the outer surface at equal intervals, and an endless chain 0.
Chain guide 01 for refracting the upper outer surface of 8 in a V shape
It is formed from 0 and.

In such a finger plate inserting mechanism 05, the conveyor 03 moves in the forward direction 02 at the moving speed v ₁ , and the moving speed v ₂ slower than the moving speed v _1.
When the endless chain 08 moves in the forward direction 02 at
In (A), at the position of the sprocket 07, the finger plate 09 projecting from the endless chain 08 to a position slightly obliquely rearward and upward by a height h, the conveyor plate 0 is advanced as the endless chain 08 advances.
Finger board insertion hole 011 (Fig. 4 (C))
), The finger plate 09 is projected vertically on the conveyor 03 while the endless chain 08 is advanced to the V-shaped bending portion of the chain guide 010.
The moving speed v ₁ of the can 01 on the conveyor 03 is set to the moving speed v
By advancing to the position of the sprocket 06 while restraining to ₂ , a predetermined gap S is formed between it and the preceding can body 01. After that, the four in-line one-piece cans 01 released from the restraint of the finger plate 09 are conveyed to the boxing machine (not shown) downstream at the moving speed v ₁ while maintaining the gap S, and the four cans 01 are transferred there. Cans 01 are integrally boxed.

However, such a finger plate insertion mechanism 05 has the following drawbacks when the can body 01 has a small can diameter and a tall and unstable shape. (1) Since the finger plate insertion hole 011 is limited to a relatively small size and the height h of the finger plate 09 must be increased, as shown by the chain line in FIG. or provided finger plate 09a of h _a, since the equal or a smaller angle of refraction theta _a chain guide than theta order to reduce the theta angle of refraction of the chain guide 010, finger plates inserted the required distance L fingers plate insertion required distance L _a , which results in a larger finger plate insertion mechanism and therefore a less economical device. (2) Also, with respect to the position of the finger plate insertion hole 011
Since the gap position of each can body 01 is displaced due to the accumulation of dimensional error of each can body 01, and each can body 01 is damaged or pushed up by the finger plate 09, the endless chain 0
8 must be attached to the joint between the finger plate 09 and the finger plate 09, and the inclination of the finger plate 09 must be regulated by a cam track rail, etc., and as a result, the finger plate insertion mechanism becomes complicated, thus reducing the economical efficiency of the device. To do.
