The adhesive application means 78 can apply an adhesive to the outer surface of the folded flap 18 bent by the bending guide 66 by spraying an adhesive such as hot melt from the spray nozzle 78a at the second folding position. It is configured as follows. Here, when the partition 16 is loaded into the box 10 from the opening 10a, the adhesive application unit 78 sprays the adhesive from the spray nozzle 78a on the outer surface of the folded flap 18 and adheres it linearly. Apply the agent.

  A method for supplying the partition 16 using the above-described supply device will be described. One partition 16 taken out by the take-out means 38 from the partition hopper 36 in which a plurality of partitions 16 are integrated is arranged in a posture in which the take-out arm 39 is rotated to stand from the take-out position to the delivery position (FIG. 2). And FIG. 5 (a)). When the holding means 42 and 42 are moved downward from the standby position by the moving means 46, the holding members 54 and 57 are brought close to the intermediate partition 16 held by the take-out means 38 at the receiving position so as to hold the partition panel 17. It is put between the members 54 and 57 and sandwiched. The suction of the take-out means 38 is released, and the partition panel 17 is sandwiched between the folding members 54 and 57 inside the folding line of the folding flap 18, and the partition 16 is received from the take-out means 38.

The abutting members 81, 81 of both folding guides 66, 66 that have been retracted to the retracted position when the partition 16 is transferred from the take-out means 38 to the holding means 42, 42 are moved to the first bending position. With both abutting members 81, 81 arranged at the first bent position, the holding means 42, 42 are rotated by the rotating means 60, so that the partition panel 17 is the same as the diagonal line of the opening 10 a of the box 10. The posture of the partition 16 is changed so that the inclined posture becomes an inclined angle. Here, since both the abutting members 81, 81 are moved and positioned to the first folding position before the middle partition 16 is rotated, when the middle partition 16 is rotated, one folding flap is provided. 18 is controlled to rotate by abutting against one abutting member 81 facing the one side surface, and bends from the crease to the other side surface, and the other folded flap 18 is the other side facing the other side surface side. The rotation is restricted by abutting on the abutting member 81 and is bent from the crease to the one side surface (see FIG. 5B). After the intermediate partition 16 is in the inclined posture, the contact members 81 and 81 are moved closer to each other from the first bent position toward the second bent position, whereby the corresponding bent flap 18 is moved by the contact member 81. Is further pushed inward to bend the folding flap 18 with respect to the partition panel 17 by 90 ° or more. Here, when the contact member 81 moves forward to the second bent position, the bent flap 18 has an angle at which the front end faces the left and right panels 13 when the partition 16 is inserted into the box 10. bent up (see FIG. 5 (c)). In addition, you may make it move the contact member 81 to a 2nd bending position until it becomes the said inclination attitude | position. By lowering the locking member 70 of the maintaining means 64 from the retracted position to the locking position, the locking member 70 is caught by the folding flap 18 that is going to return in the direction opposite to the folding direction, and the holding position by the holding means 42, 42. Both folded flaps 18, 18 extending outward are held in a state where they are bent in different directions.

  The intermediate partition 16 in an inclined posture faces the opening 10a of the box 10 which is conveyed to the partition supply position by the conveyor 20 and positioned by the positioning means 28, 32, and is partitioned at an inclination angle corresponding to the diagonal line of the opening 10a. The panel 17 is held so as to extend. The box 10 is transported to the partition supply position and positioned until the middle partition 16 is taken out from the partition hopper 36 and the folding flap 18 is bent. The holding means 42 and 42 are lowered from the receiving position toward the loading position, and the partition 16 in which the partition panel 17 is inclined and the folded flaps 18 and 18 are bent is inserted into the box 10. When lowering the inner partition 16, each of the contact members 81 guides the outer surface of the folded flap 18 in a bent state, and sprays the adhesive from the spray nozzle 78 a of the adhesive applying means 78. An adhesive is applied linearly above and below the outer surface of the folded flap 18. The rotating means 60 is rotated in the opposite direction to the case where both the holding means 42 and 42 are inclined, and the inclined partition 16 is extended over the front and rear panels 12 and 12 where the partition panel 17 is opposed to the box 10. The posture is changed in the box 10 so as to be divided into two to divide the inside of the box 10 (see FIG. 5D).

  After the intermediate partition 16 is positioned in the partitioning posture, the locking member 70 of the maintaining means 64 is raised from the locking position to the retracted position to release the folding flap 18 so that the folding flap 18 is bent. The outer surface comes into contact with the front and rear panels 12 by a reaction force opposite to the above. Then, the folding flap 18 is pressed against the front / rear panel 12 by the pressing member 72 of the pressing means 65 to join the outer side surface of the folding flap 18 coated with the adhesive and the front / rear panel 12 (see FIG. 5 (e)). ). As a result, the inside of the box 10 is divided into two by the partition panel 17 extending between the front and rear panels 12 and 12 in parallel with the left and right panels 13, and the folded flaps 18 and 18 extend along the corresponding front and rear panels 12 and 12. In this state, the partition 16 is loaded into the box 10.

  Next, functions and effects of the embodiment will be described. According to the supply device and the supply method described above, the partition 16 is placed in the state in which the partition panel 17 is in the inclined posture and the folding flaps 18 and 18 provided continuously on both sides of the partition panel 17 are folded and held by 90 ° or more. Since the box 10 is loaded into the box 10 through the opening 10 a of the box 10, the partition 16 is attached to the front and rear panels 12 and 13 using an oblique width longer than the interval between the front and rear panels 12, 12 facing each other in the box 10. The rectangular tube box 10 can be smoothly loaded from the opening 10a without interference. Here, when the position of the partition 16 is changed so that the partition panel 17 is inclined, the partition 16 is held so as to face the opening 10a of the positioned box 10, so that the partition 16 is left as it is. In this state, it can be loaded into the box 10 from the opening 10a. Moreover, when the posture of the partition 16 is changed, the partition panel 17 is held at the same inclination angle as the diagonal line of the opening 10a having the longest width in the box 10, so that the partition 16 is moved from the opening 10a into the box 10. It can be loaded with a margin.

  The partition 16 is loaded into the box 10 with the partition panels 17 being inclined with respect to the front and rear panels 12 of the box 10 and holding the folded flaps 18 and 18 by being bent at 90 ° or more. Since it is placed in the box 10 and positioned in the partitioning posture, the partition length dimension of the partition panel 17 can be set so as to eliminate the gap with the front and rear panels 12. That is, when the inside of the box 10 is divided into two parts, the partition panel 17 supports the box 10 in close contact with the front and rear panels 12 and 12 so that the box 10 can be reinforced to obtain a strong box 10. For example, even if a relatively heavy article such as a pouch filled with liquid is supplied for each row in which the partition 16 is sandwiched in the box 10, the box 10 can be distributed without causing insufficient strength. It can prevent damage at times. Moreover, the articles accommodated in the box 10 can be protected from external pressure.

  Moreover, the folded flap 18 applied with the adhesive by the adhesive applying means 78 is pressed against the front and rear panels 12 by the pressing means 65 in the box 10, and the bent flap 18 and the front and rear panels 12 are joined with an adhesive. The partition 16 is fixed inside the box 10. Thereby, the box 10 can be supported by the partition 16 fixed so as not to rattle between the front and rear panels 12 and 12, and the box 10 having higher strength can be obtained.

  As described above, when the partition 16 is loaded in the box 10 that is box-shaped and opened on the top surface, interference between the partition 16 and the box 10 can be prevented, so that the partition 16 can be configured with a simple configuration. The supply operation can be automated. That is, a corrugated sheet folded in a sheet shape is opened in a rectangular tube shape, formed in a box 10 having a bottom surface closed and a top surface opened, and then a plurality of articles are supplied from the opening 10a and then the opening 10a side The above-described supply device and supply method can be suitably used for a boxing machine that bends and seals the box flap 11.

When the partition 16 is rotated to the inclined posture, the folding flaps 18 and 18 are bent by the contact with the contact member 81 located at the first folding position, so that the posture change of the partition 16 is changed. Therefore, the cycle time can be shortened by reducing the number of processes compared to the case where the folding flaps 18 and 18 are bent separately. In addition, since the folding flap 18 is bent by the contact with the contact member 81 accompanying the change in the posture of the inner partition 16, the configuration relating to the bending of the folding flap 18 can be simplified. After the folding flap 18 is bent by contact with the contact member 81 located at the first bending position, the folding flap 18 is moved by a simple operation of moving the contact member 81 forward toward the second bending position. Can be bent to a desired angle. Here, since both the holding means 42 and 42 hold | maintain the folding ruled vicinity with the folding flaps 18 and 18 in the partition panel 17, the deformation | transformation of the partition panel 17 is prevented and each folding flap 18 is folded down. Can be bent properly. And since the folding flap 18 is bent and held until the tip thereof is at an angle that faces the left and right panel 13 when the partition 16 is inserted into the box 10, the partition 16 is opened from the opening 10a to the box 10. When loading, interference between the bent flaps 18 and 18 and the box 10 can be prevented appropriately. As described above, the folding flap 18 is bent by the contact with the contact member 81 located at the first folding position as the posture of the partition 16 changes, and the first folding position of the contact member 81 is changed from the first folding position. The folding flap 18 can be further bent by advancing to the two folding positions, and the folding flap 18 is separated from the partition panel 17 by the configuration of one simple folding guide 66 corresponding to each folding flap 18. It can be bent to a desired angle of 90 ° or more.

  The folded flap 18 of the partition 16 housed in the box 10 can be held in a simple configuration in which the folded flap 18 folded by the folding guide 66 is hooked and locked by the locking member 70. And the device can be made more compact.
