To explain an example of this operation, the folded carton in a pre-laminated state is separated and taken out one by one, and then left and right side surfaces and a bottom surface, which are main surfaces of the carton, are formed by an assembling process. It is conveyed to the boxing process in the state where it was put.

In the box packing process, for example, a group of canned beers divided into a certain number is pushed by a pushing member (pusher) from one end of the front and rear surfaces (the upper lid and the lower lid) in an open state, and is pushed into the box. (Filled).

[0004] At this time, the operation rate cannot be improved if the carton is stopped and packed in boxes each time canned beer is filled. Therefore, while moving the carton and a fixed number of canned beer groups together at a constant speed, the canned beer group is gradually pushed in the direction perpendicular to these transport directions, and the canned beer group is filled into the carton. Can be
The carton in which the filling of the canned beer group is completed is assembled into a complete carton box in the next closing step, and a predetermined portion is adhered to be completed as a shipping carton.

FIG. 1 is a schematic perspective view for explaining the whole structure of the method for packing a cylindrical object according to the present invention, and FIG. 2 is a diagram for explaining the whole structure of the method for packing a cylindrical object according to the present invention. FIG. 3 is a schematic side view showing a structure for elevating the other end in the longitudinal direction of the carton, which is a main part of the present invention, with time, and FIG. 4 is a schematic plan view partially showing a necessary part in FIG. 5 (a) and 5 (b) are schematic front views showing the states of and in FIG. 3, respectively.

In the present invention, the cylindrical object to be boxed is a cylindrical object (container) having a relatively high center of gravity such as canned beer.
When the diameter of the bottom surface of the cylindrical object is D and the position of the center of gravity G from the bottom surface of the cylindrical object is D, the value of the ratio D / G is 0.5 to 0.5.
The object satisfying 9 is a suitable object. In the present invention,
Hereinafter, a description will be given by taking a canned beer as an example of a suitable cylindrical object to be packed.

In the case of the embodiment shown in FIG. 1, two rows of conveyors 10 and 20 are running in parallel at the same speed, and one of the conveyors 10 has canned beer 7 to be packed in a box continuously from the upstream side. It is transported in an upright state.

On the other conveyor 20, cartons for packing are taken out one by one from the folded state and assembled in a predetermined form (in the middle of assembling). (Transverse to the transport direction). That is, the conveyor 20
, A carton for packing is supplied, and an opening 31 is formed in at least one of the longitudinal directions of the carton 30 (closer to the canned beer). An apparatus 90 for assembling the carton into a semi-finished state so that 71 can be filled
(FIG. 2) is provided (carton assembly and delivery step).

The group of canned beer 70 continuously conveyed from the upstream side and temporarily stored in the conveyor 10 is divided into a fixed number, and is divided into a predetermined number of boxes (12 in FIG. 1). ) Can beer groups 71 are formed at predetermined intervals (cut-out device 100 (FIG. 2)). Canned beer group 7 formed in this way
1 is continuously sent out at constant intervals by the conveyor 10 (cutting-out step).

The canned beer group 71 continuously sent out at regular intervals is fed to a pusher device (a push plate 80 and a stroke member 8 shown in FIG.
1), is gradually moved toward the carton (in a direction perpendicular to the transport direction), and finally the canned beer group 71 is pushed into the carton and filled (pusher filling step).

In the pusher filling step, the method of pushing the canned beer group 71 is a main part of the present invention.
That is, the other end portion of the carton located on the side opposite to the opening 31 of the carton 30 serving as a filling port is relatively lifted to form an upward slope along the longitudinal direction of the carton, and the upward slope is raised. Canned Beer Group 7
1 is pushed and filled.

This situation will be described in more detail with reference to FIGS.

As described above, FIG. 3 is a schematic side view showing a structure for lifting the other end in the longitudinal direction of the carton, which is a main part of the present invention, with time, and FIG. 4 is a schematic plan view partially showing FIG. 5 (a) and 5 (b) are schematic front views showing the states of and in FIG. 3, respectively. In addition,
In these figures, the top surface of the carton 30 is shown in FIG.
Although not completely covered as shown in FIG. 3 but in a half-open state, FIGS.
In the description, since the released state of the upper surface of the carton 30 does not particularly matter, the drawings of FIGS. 3 to 5 are simplified and drawn in a substantially rectangular parallelepiped shape to facilitate understanding of the invention. .

As shown in FIGS. 3 and 4, the carton 30 has an opening 31 of the carton 30 serving as a filling port of the canned beer group 71 (this side finally corresponds to an upper lid portion for convenience of explanation). The upper lid portion 32 and upper lid side flaps 33, 33 located on the side surface thereof.
Remain open as shown in FIG. On the other hand, at the other end of the carton located on the side opposite to the opening 31, the lower lid portion 37 remains open (not bent) as shown in FIG. The lower lid side flaps 38, 38 located are bent and closed. A traveling guide plate 50 is formed along the transport direction so as to slide on the closed lower lid side flaps 38, 38. The traveling guide plate 50 is set at a predetermined height position (FIGS. 3 and 5), and the lower lid portion 37 which is open and extended during traveling is extended.
However, they pass under the travel guide plate 50 so as not to hit the travel guide plate 50 (FIG. 4). An ascending guide 40 is formed below the lower lid portion 37 between certain areas where pusher filling works (for example, area B in FIG. 2) (FIGS. 3 to 5). As shown in FIG. 3, the ascending guide 40 gradually moves from the position lower than the transport reference surface height S (same as the height of the conveyors 10 and 20) along the transport direction to the transport reference surface height S. And maintaining the final height H at a certain distance (until filling is completed). In the pusher filling process, the ascending guide 40 allows the other end portion of the carton located on the opposite side to the opening 31 of the carton 30 to be the filling port of the canned beer group 71, in particular, the lower lid portion in the open state. A portion corresponding to 37 runs on the ascending guide 40 and is gradually lifted. That is, the lower lid portion 37 starts sliding contact with the ascending guide 40 gradually from the state of FIG. 3, and one side of the carton 30 is lifted up to the height H in the state of.

As a result, the canned beer group 71 is filled in the carton in an inclined state as shown in FIG. 5 (b), so that the plurality of cans are mutually pushed toward the pusher (push-in member) during packing. The can is moved to be pushed up while receiving the load (the can is tilted in the direction opposite to the direction in which it is pushed, and is packed in a box). .

Since the ascending guides 40 are provided at regular intervals to complete the can packing, when the packing is completed, the carton is in a state parallel to the original conveying surface (S). Return to. Further, it is desirable that the ascent guide 40 has a specification such that its height H can be changed arbitrarily.

In the preferred embodiment of the present invention,
Although an opening is formed in the longitudinal direction of the carton and canned beer is inserted from this longitudinal direction, the inserting direction is not particularly limited.

[0025]

According to the present invention, the continuously upright conveyed cylindrical object is divided into a fixed number and divided into a number of boxed pieces. In the feeding step, the cutting step and supplying the carton for packing, at least an opening is formed in one side of the carton in the longitudinal direction so that the divided number of cylindrical objects can be filled from the opening. , And assemble the carton into a semi-finished product, and
The above-mentioned pusher filling step, comprising: a carton assembling and sending step; and a pusher filling step of pushing and filling the fed tubular group into a carton. In, the other end portion of the carton located on the opposite side to the opening of the carton serving as the filling port of the cylindrical group is relatively lifted,
An upward slope is formed along the longitudinal direction of the carton, and since the cylindrical group is configured to be filled by being pushed in so as to raise the upward slope, the can is prevented from overturning at the time of boxing and is stable. Box packing can be realized.
