DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In the embodiments, the same components as those in the above-described conventional technology are denoted by the same reference numerals, and description thereof will be omitted.

In the drawing, reference numeral 11 denotes a pusher as a pushing member provided in a box packing device according to the present embodiment. The pusher 11 has an air cylinder (not shown) whose base end is not shown in the same manner as the pusher 6 described in the prior art. And the like, and a rectangular contact plate 13 provided on the distal end side of the rod portion 12, but the contact plate 13 has two engagement grooves 14. , 15
, And four guide protrusions 16, 16,... Forming both side surfaces of the engagement grooves 14, 15, are formed.

Here, the engaging grooves 14 and 15 are formed at an angle convenient for inclining the crimping portion 1A of the tubular container 1 with respect to the carton 3, for example, the contact plate 1
3 is formed along the diagonal line, and the center 13A of the contact plate 13 is formed.
Intersect at Also, both side surfaces of the engaging grooves 14 and 15 are provided with four guide surfaces 16D, 16D,... Or 16E, 16E,.
It is constituted by.

Reference numerals 16, 16,... Denote guide projections. Each of the guide projections 16 protrudes from the top of the contact plate 13 at the midpoint of the four sides to form an apex 16A.
The ridge line 16B is directed toward the center 13A of the contact plate 13 and the ridge lines 16C, 16C,.
Are formed in a triangular pyramid shape by extending,
6, on both sides of the ridge line 16B, the ridge line 16B and the ridge line 16C,
16C, which are symmetrical to each other by 16C,
16E is formed, and each guide surface 16D or 16E
Are arranged in two rows facing each other, each of which constitutes both side surfaces of the engaging groove 14 or 15.
Each guide surface 16D expands in a substantially V shape from the position of the engagement groove 14 toward the ridge lines 16B and 16C, and each guide surface 16E extends from the position of the engagement groove 15 toward the ridge lines 16B and 16C. It is formed so as to expand in a substantially V shape.

The pusher 11 according to the present invention is configured as described above, and its basic operation is not particularly different from that of the prior art.

In this embodiment, however, the contact plate 13 constituting the pusher 11 is provided with flat-bottomed engaging grooves 14 and 15 along a diagonal line, and both side surfaces of the engaging grooves 14 and 15 are in contact with each other. Each of the guide surfaces 16D, 16D,... Or 16E, 1 determined by the respective ridge lines 16B and 16C of the four triangular pyramid-shaped guide protrusions 16, 16,.
, And each of the guide surfaces 16D, 16E
Are formed so as to expand in a substantially V-shape from the positions of the engagement grooves 14 and 15, the following operational effects are obtained.

That is, when the crimping portion 1A of the tubular container 1 is pushed by the pusher 11 of this embodiment, the crimping portion 1A comes into contact with the ridge 16B or 16C of each guide projection 16 at some place. Here, since the apex 16A of each guide protrusion 16 is sharp, even if the crimping portion 1A of the tubular container 1 comes into contact with each apex 6A, the crimping portion 1A immediately rotates by an appropriate angle to guide the protrusion. 16 comes into contact with each guide surface 16D or 16E side. Then, as the pusher 11 moves in the direction indicated by the arrow Y in the drawing, the tubular container 1 moves in the transport bucket 2A into the carton 3, and at this time, the crimping portion 1A The guide 16 is guided toward the engagement groove 14 or 15 along each guide surface 16D or 16E of the projection 16, and is rotated by an appropriate angle to engage in the engagement groove 14 or 15.

Thus, the crimping portion 1A of the tubular container 1
Is brought into engagement with the engaging groove 14 or 15, so that the contact plate 13 pushes the crimping portion 1A of the tubular container 1 into the carton 3
By further moving the contact plate 13 in the direction indicated by the arrow Y in this state, the tubular container 1 can be inserted into the carton 3 in a normal state as shown in FIG. As a result, as shown in FIG. 6, the crimping portion 1A is held inside the carton 3 and the carton 3 is bent, which can effectively solve the problem of the prior art in which poor packing is caused.

In the above embodiment, the case where two engagement grooves 14, 15 and four guide projections 16 are formed on the tip end side of the contact plate 13 has been described as an example. However, the present invention is not limited to this. For example, one engagement groove is formed at a predetermined angle on the distal end surface of the contact plate 13, and both side surfaces of the engagement groove are V-shaped so as to increase their mutual distance toward the distal end side. Alternatively, it may be configured by providing two triangular pyramid-shaped guide protrusions each having a tapered triangular guide surface.

In the above embodiment, the tubular container 1
Is transported intermittently by the container transport conveyor 2 and the carton 3 is transported intermittently by the carton transport conveyor 5. Instead, the tubular container 1 and the carton 3 are transported continuously by the respective conveyors. Alternatively, the tubular container 1 may be sequentially inserted into the carton 3 during the transportation. In this case, the plurality of pushers 11 may be expanded and contracted while being moved in synchronization with the container transport conveyor 2.

As described in detail above, according to the present invention, a contact plate is provided at the distal end side of the pushing member for contacting the crimping portion of the tubular container, and the contact plate has a predetermined angle with respect to the carton. The crimping portion is inclined only by engaging the crimping portion of the tubular container to hold the tubular container in an inclined state, and the crimping portion of the tubular container is brought into contact with the crimping portion by contact with the crimping portion of the tubular container. Since a plurality of guide protrusions for guiding to the tube container are formed, when the contact plate moves and comes into contact with the crimping portion of the tubular container,
The crimping portion is guided by the inclination of the guide protrusion on the contact plate and engages with the engagement groove, and the tubular container is inserted into the carton while being inclined by a predetermined angle, and has a wide crimping portion. However, it is possible to effectively prevent poor packing such as bending or piercing the carton by holding the inside of the carton, thereby improving the efficiency of the packing work and the reliability of the product.
