The articles to be packaged are fed one by one through the guide 17 connecting the guide 14 on the table 13 and the star wheel 15 so as to be extruded from the turntable 13 to the star wheel 15 and arranged side by side on the carton conveyor 5. The object to be packaged from the star wheel 15 is transferred to the bucket conveyor 19 synchronized with the carton conveyor 5, and the object to be packaged conveyed on the bucket conveyor 19 is inserted into the carton by the inserting means of the inserting section 9. The turntable 13, the star wheel 15, and the bucket conveyor 19 serve to supply the objects to be packaged. Device is constructed.

Next, the carton into which the object to be packaged is inserted is conveyed to an adhesive section 21 provided at the front part of the carton conveyor 5, where the left and right flaps in the unfolded state of the carton are separated. After being glued and gradually raised by the guide, this carton is sent between a pair of adhesive belts 23, 23 arranged along both left and right sides of the carton conveyor 5, and rotation of pulleys 24, 25 causes the carton conveyor to rotate. Both adhesive belts 23, 23 are driven in conjunction with the conveyance by 5, and the carton is sandwiched between both adhesive belts 23, 23 so that the glued flaps are adhered and the small box of the packaged object The packaging is completed, and the objects to be packaged in the above-described box are continuously conveyed by the field conveyor 27 in front of the carton conveyor 5. It is adapted to be carried to the working process.

In FIG. 3, reference numeral 29 is a main control box of the box packing device.

By the way, the above-mentioned carton magazine 1,
The detailed configurations of the take-out section and the correction section 3 are as shown in FIGS. 4 and 5, and as shown in FIG.
Is composed of a front holding member 1a which is one side holding member and a rear holding member 1b which is the other side holding member. Both holding members 1a and 1b are movable in the front-rear direction by support brackets 1c and 1d, respectively. Supported, both members 1
The front and rear positions of both holding members 1a and 1b are set so that the distance between a and 1b is slightly larger than the length of the carton K to be held in the front-rear direction so that the carton K can be loaded between the holding members 1a and 1b. Both holding members 1 are arranged so that the carton K and the two actuating members 31, 31 are substantially parallel to each other when the carton K is picked up by the both actuating members 31, 31 of the take-out section which will be described later in detail.
Both holding members 1 with the upper parts of a and 1b inclined rearward
Although not shown in FIG. 4, at least one locking claw is provided at the lower end of each of the holding members 1a and 1b, and these locking claws are provided in the carton. By locking to the lower surface of K, both members 1a, 1
A plurality of cartons K are held in a stacked state between b.

Further, as shown in FIGS. 4 and 5, two take-out portions are provided on the upper surfaces of the front end portions of the two actuating members 31, 31 which are elongated in the front-rear direction. And a rear end portion of both actuating members 31 and 31 is axially fixed to a horizontal rotating shaft that rotates in both directions by an actuator (not shown). , 31 are kept substantially horizontal, and the front end portions of both actuating bodies 31, 31 are moved upward by the rotation of the rotary shaft in one direction, and the respective suction cups 33 are placed on the lower surface of the lowermost carton K of the carton magazine 1. The inside of each suction cup 33, which abuts and abuts on the lower surface of the carton K by the operation of the suction device (not shown), becomes a negative pressure, and each suction cup 33 adsorbs to the carton K. Opposite direction By rotating both operating body 3
1, 31 are moved downward and the lowermost carton K of the carton magazine 1 is released from the state of being locked by the locking claws and taken out from the carton magazine 1. Immediately after that, the operation of the suction device is stopped and The suction cup 33 is no longer adsorbed to the carton K, and the carton K taken out falls under its own weight.

Next, the correction unit 3 is constructed as shown in FIGS. 4 and 5, and as shown in FIG. A pair of feed guides 35, 35 movably provided on the upper side of the feed guides 35, 35, as shown in FIG. And 37.

By the way, when the actuating members 31, 31 of the take-out section take out the carton K of the carton magazine 1, the hooks 37, 37 of the feed guides 35, 35 of the correcting section 3 fall into the carton. Both feed guides 35 and 35 are moved backward and held in a state of being extended so as to be located slightly behind the rear end of K, and when the carton K falls on both feed guides 35 and 35 thereafter. When the drive means starts to move the both feed guides 35, 35 forward, and thus the both feed guides 35, 35 move forward,
The carton K on the both feed guides 35, 35 relatively slides on the both feed guides 35, 35 because the carton K on the both feed guides 35, 35 tries to stay in the same position due to the inertia. The trailing edge of both hooks 37,
37, and the position of the carton K is corrected so that the front and rear edges of the carton K are aligned in both feed left and right directions.
The carton K moves forward together with the feed guides 35, 35 while being engaged with the hooks 37, 37.

Therefore, while the taken out carton K is falling due to its own weight, for example, it jumps forward and the positions of the cartons dropped on the feed guides 35, 35 are greatly displaced, and the cartons on the feed guides 35, 35 are displaced. Even when the front and rear edges of K are not oriented in the left-right direction, the carton K is corrected to the normal position by the action of the correction section 3 as described above.

Then, a distance of a little larger than the thickness of the carton K from the upper surface of both the feed guides 35, 35 is provided between the two feed guides 35, 35 in front of the carton K dropped on the both feed guides 35, 35. Two presser guides 39, 39 are provided separately from each other, and both feed guides 35, 35 are provided.
The carton K, which is moved forward by the above, is fed to the lower side of the double presser guides 39, 39, and further, the double presser guide 3
By rotation of the feed roller 41 arranged in front of 9, 39, the cartons K on both feed guides 35, 35 are delivered onto the carton conveyor 5.

[0013]

However, in the above-mentioned conventional apparatus, if the surface of the carton K is printed and coated with poor slippage, both feed guides 35, 3 are provided.
Even if 5 moves to the front, the carton K will be fed by the double feed guide 3
Since it does not slide well on 5, 35, both feed guides 3
The rear end edge of the carton K on the 5,35 has both hooks 37,37.
, The front and rear edges of the carton K do not coincide with each other in the left-right direction, that is, the carton K is fed with a large deviation, and is fixed to both feed guides 35, 35. In some cases, conveyance failure such as the carton K being clogged with the guides 39, 39 may occur.

The problem to be solved by the present invention is to make it possible to easily correct the position of a carton that has fallen to the take-out portion to a normal position and prevent the occurrence of conveyance defects, irrespective of whether the surface of the carton is slippery or not. To do.

[0015]

According to the first aspect of the present invention,
