Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a box gluing device having a main body and a flap piece adhered to an adhesive piece forming the main body.

``Prior Art'' Conventionally, as a gluing device, a gluing mechanism applies glue to a desired position on the bonding surface between the adhesive piece and the flap piece of the box, and then the flap piece is bonded to the adhesive piece using a pressure bonding member. There is a method (Japanese Unexamined Patent Publication No. 51-40226).

``Problem to be solved by the invention'' In this case, if the object stored in the box has a high rigidity and has an outer surface that follows the surface of the adhesive piece, the above-mentioned pressure bonding member can be used to attach the flap piece to the adhesive piece. There has never been a case where the free end of the adhesive piece escapes into the inside of the box when crimped onto the box, resulting in poor adhesion. Even if it is large, if a space is formed in the box at the part where the flap piece is crimped, such as with a tapered shape, the adhesive piece may escape inward when the flap piece is crimped, resulting in poor adhesion. It was hot.

"Means for Solving the Problems" In view of such circumstances, the present invention includes forming one side of the flap piece continuous with the main body part, and making the free end of the flap piece protrude from the main body part, In addition, one side of the adhesive piece is formed continuously on the main body part, and the free end of the adhesive piece faces the main body part near the flap piece. A conveyor conveys the box, and the flap piece is bonded. a crimping member movable between an advanced position for crimping the flap piece and a retracted position separated therefrom; the adhesive is applied to a desired position on the bonding surface between the adhesive piece and the flap piece, and the crimping member is used to press the flap piece together; In the gluing device that presses the flap piece to the adhesive piece to bond them together, there is a forward position in which the body part near the flap piece is brought into contact with the flap piece and pressed, and the main body part is pressed against the free end of the adhesive piece; A movable pressing member is provided at a separate retreat position, and the pressing member presses the flap piece to the adhesive piece while the pressing member holds the adhesive piece in pressure contact with the main body.

"Function" According to the above-described configuration, the free end of the adhesive piece can be pressed against the main body and restrained by moving the pressing member to the forward position, thereby ensuring that the adhesive piece escapes inward. The flap piece can be crimped onto the adhesive piece while preventing this from happening.

"Example" The present invention will be explained below with reference to the illustrated example.
FIG. 1 shows a perspective view of a box 1, the main body part 2 of which is formed by bending a flat blank sheet, which includes a rear adhesive piece 3 and a side adhesive piece 4. , 5. The rear adhesive piece 3 is located on the rear side in the transport direction of the box 1, and the side adhesive pieces 4 and 5 are located on both sides of the box 1. The parts are indicated by 3b, 4b, and 5b. A rear flap piece 6 that is bonded to the rear adhesive piece 3 extends from the rear upper part of the main body part 2.
Side flap pieces 7, 8 which are bonded to the side adhesive pieces 4, 5 extend from upper and lower positions on both sides of the flap.

In this embodiment, the dimensions of each of the adhesive pieces 3, 4, and 5 are adjusted such that the free end tip 3a of the rear adhesive piece 3 contacts the main body 2 at the base of the rear flap piece 6, and the side adhesive Both free ends of pieces 4 and 5 4
b, 5b are set to contact the main body portion 2 at the base of the side flap pieces 7, 8, respectively.

Next, in FIGS. 2 and 3, reference numeral 10 denotes a conveyor that intermittently conveys the boxes 1, and the boxes 1 are conveyed to the gluing device 1 according to the present embodiment by the conveyor 10.
1 and stopped, the box 1 having the configuration shown in FIG. As a result, glue is applied to desired positions on the adhesive surfaces of the adhesive pieces 3, 4, 5 and the flap pieces 6, 7, 8.

At the stop position of the box 1, there is provided a rear crimping member 13 above which the rear flap piece 6 is bent and crimped to the rear adhesive piece 3, and side flap pieces 7 and 8 are attached on both sides of the side adhesive piece. Side crimping members 14 and 15 are provided for crimping the parts 4 and 5.
The rear pressure bonding member 13 is provided at the tip of the arm 16, and the base of the arm 16 is connected to the conveyor 1.
The rotary shaft 18 is fixed to a rotary shaft 18 that is rotatably supported on the upper machine frame 17 above 0, and the rotary shaft 18 is linked via a lever 19 to a cylinder device 20 that swings the arm 16 and the rear crimping member 13. I'm letting you do it. Note that the lower surface of the upper machine frame 17 is set at a height that corresponds to the upper surface of the box 1.

On the other hand, a pair of parallel guide rods 21 extending horizontally are fixed to each of the side crimping members 14 and 15, and each guide rod 21 is slidably supported by a bearing 23 provided on the lower machine frame 22. Each of them can move forward and backward toward the box 1, and each side pressure bonding member 14, 15 is linked with a cylinder device 24 that moves the side pressure bonding member forward and backward.

However, at a position above the box main body 2 close to the rear flap piece 6, there is a rear pressing member 30 that presses the main body 2 between it and the conveyor 10.
In addition, side pressing members 31 and 32 are also provided at upper positions of the box body 2 close to the side flap pieces 7 and 8, respectively. Each pressing member 30,
31 and 32 are raised and lowered by actuators 33, 34, and 35 such as solenoids, respectively, so that a desired position of the main body 2 can be pressed at the lowered position.

In the above configuration, when the box 1 shown in FIG.
3, 34, and 35 respectively operate to press each pressing member 3.
0, 31, 32 are lowered. As a result, the desired position of the main body part 2 is pinched and pressed by each pressing member and the conveyor 10, and the free end tip 3a of the rear adhesive piece 3 and the side adhesive pieces 4, 5 are pressed. The free end side portions 4b, 5b are pressed against the main body portion 2 and restrained, thereby preventing them from freely escaping into the inside of the box 1.

In this state, each crimping member 13, 14, 1
5 are actuated by cylinder devices 20, 24 respectively to attach each flap piece 6, 7, 8 to the adhesive piece 3,
4 and 5 and adhered with the above-mentioned glue.

When the gluing is completed in this way, each crimping member and pressing member are returned to their original positions, and then the box that has been glued is taken out of the gluing device 11, and a new box 1 is brought in, and the above-mentioned box 1 is carried in. The same operation is repeated.

In addition, in the above embodiment, the pressing members 30, 31, 3
2 and the conveyor 10, but if pressing is to be carried out in the horizontal direction, for example, it is of course possible to provide a dedicated pressing member in place of the conveyor 10.

"Effects of the Invention" As described above, according to the present invention, even if the items stored in the box are easily deformed or have high rigidity, the part where the flap piece is crimped, such as a tapered shape, can be Even when a space is formed in the box, the flap piece can be reliably bonded to the adhesive piece.
