[0028]

[0029] FIG. 1 is a perspective view for explaining a box adhesive accessory moving device according to one embodiment of the present invention, FIG. 2 is a front view for explaining a box adhesive accessory moving device illustrated in FIG. 1, FIG. 3 is a plan view for explaining a box adhesive accessory moving device illustrated in FIG. 1, FIG. 4 is a partial side view for explaining a box adhesive accessory moving device illustrated in FIG. 1, FIGS. 5 and 6 are side views for explaining fixing and releasing of a clamp according to the operation of a push pin, and FIG. 7 is a side view for explaining releasing of a clamp according to the operation of a push bolt.

[0030] Referring to FIGS. 1 to 7, the box adhesive accessory moving device (100) is for moving box adhesive accessories (10), and may largely include a moving shaft (110), brackets (120), a first moving unit (130), first sensors (140), a second sensor (150), a second moving unit (160), an input unit (170), and a control unit (180). At this time, the box adhesive accessories (10) are used for bonding packaging boxes, and may include a plurality of nozzles that spray adhesive onto the packaging box, a plurality of fold-over hooks that fold an unfolded packaging box to overlap, a plurality of guides that press the packaging box to maintain the packaging box in a folded state, a plurality of brushes for removing foreign substances remaining on the packaging box or adhesive sprayed beyond the bonding area, etc. The box adhesive accessories (10) are arranged in the left-right direction and may be positioned above the packaging box.

[0031] The above moving axis (110) extends along the left-right direction. The cross-section of the above moving axis (110) may be circular.

[0032] The above brackets (120) each fix the box adhesive accessories (10) and can move in the left-right direction along the movement axis (110). As the brackets (120) move in the left-right direction, the box adhesive accessories (10) can also move in the left-right direction.

[0033] It is preferable that each of the above brackets (120) be formed by a combination of vertical bars and horizontal bars for fixing the box adhesive accessory (10), but it is not limited thereto and may be formed in various shapes.

[0034] Each of the above brackets (120) includes a clamp (121) for contacting the moving axis (110) and fixing the bracket (120) to the moving axis (110).

[0035] When the fixation of the clamp (121) is released, the brackets (120) can move in the left-right direction. In addition, when the movement of the brackets (120) in the left-right direction is completed, the movement axis (110) can be fixed with the clamp (121) to prevent the brackets (120) from moving in the left-right direction.

[0036] The above clamp (121) may be composed of a first clamp (122), a second clamp (123), and a coil spring (124).

[0037] The above first clamp (122) is connected to the bracket (120) and is provided to come into contact with a portion of the moving shaft (110).

[0038] The second clamp (123) is hinge-joined to the first clamp (122) and rotates around the hinge axis (123a) so as to come into contact with the remaining portion of the moving axis (110) or be spaced apart from the moving axis (110).

[0039] The first clamp (122) and the second clamp (123) may be arranged on opposite sides with respect to the moving axis (110). For example, as illustrated in FIG. 4, the first clamp (122) and the second clamp (123) may be arranged vertically with respect to the moving axis (110). Alternatively, although not illustrated, the first clamp (122) and the second clamp (123) may be arranged in the front-back direction with respect to the moving axis (110).

[0040] When the second clamp (123) comes into contact with the moving axis (110), the clamp (121) fixes the moving axis (110), and when the second clamp (123) is separated from the moving axis (110), the clamp (121) releases the fixation of the moving axis (110).

[0041] When the clamp (121) releases the fixation of the moving axis (110), the first moving unit (130) can move the bracket (120).

[0042] When the first moving unit (130) completes the movement of the bracket (120), the clamp (121) fixes the moving axis (110) to prevent the bracket (120) from moving.

[0043] The coil spring (124) is fixed at both ends to the first clamp (122) and the second clamp (123), respectively. At this time, the coil spring (124) may be positioned on the opposite side of the hinge axis (123a) with respect to the moving axis (110). The coil spring (124) provides elastic force to maintain the second clamp (123) in contact with the moving axis (110). That is, the clamp (121) can maintain the state of fixing the moving axis (110) by the elastic force of the coil spring (124).

[0044] Meanwhile, the brackets (120) may be supported by a guide member (125) such as an LM guide. At this time, the guide member (125) may extend in the left-right direction. Accordingly, the brackets (120) may be stably moved in the left-right direction.

[0045] The first moving unit (130) can move in the left and right directions by fixing the brackets (120) one by one so that the box adhesive accessories (10) are positioned at the spraying position. At this time, the first moving unit (130) can move the brackets (120) after releasing the fixation of the clamp (121).

[0046] Specifically, the first moving unit (130) may include a push pin (131), a first moving part (132), and a second moving part (133).

[0047] The above push pin (131) pushes the second clamp (123) to separate the second clamp (123) from the moving axis (110). At this time, the push pin (131) can push the second clamp (123) by passing through the through hole (122a) provided in the first clamp (122).

[0048] The first moving part (132) moves the push pin (131) back and forth so that the second clamp (123) comes into contact with the moving axis (110) or is separated from the moving axis (110). For example, the first moving part (132) can move the push pin (131) back and forth in the up-down direction or the front-back direction.

[0049] When the push pin (131) is moved by the first moving part (132) to push the second clamp (123), the second clamp (123) can be separated from the moving axis (110). That is, the clamp (121) can be released from its fixation to the moving axis (110). (See Fig. 6)

[0050] In addition, when the push pin (131) is moved in the opposite direction by the first moving part (132) and returns to its original position, the second clamp (123) can come into contact with the moving shaft (110) by the elastic force of the coil spring (124). That is, the clamp (21) can fix the moving shaft (110). (See Fig. 5)

[0051] The second moving part (133) moves the push pin (131) and the first moving part (132) in the left-right direction. When the clamp (121) fixes the moving shaft (110), the second moving part (133) cannot move the push pin (131) and the first moving part (132) in the left-right direction. Therefore, when the clamp (121) releases the fixation of the moving shaft (110) by the first moving part (132), the second moving part (133) can move the push pin (131) and the first moving part (132) in the left-right direction.

[0052] In addition, since the push pin (131) passes through the through hole (122a) provided in the first clamp (122) when pushing the second clamp (123), the push pin (131) is caught on the first clamp (122) when moving in the left-right direction. Accordingly, when the push pin (131) and the first moving part (132) move in the left-right direction by the second moving part (133), the bracket (120) can also move stably in the left-right direction.

[0053] Examples of the first moving part (132) and the second moving part (133) include a pneumatic cylinder and a pump, a linear motor and an LM guide, a rotary motor and a ball screw, a rotary motor, a pulley and a belt, a rotary motor and a gear, a rotary motor, a gear and a chain, etc.

[0054] The first clamp (122) may be provided with a push bolt (135). The push bolt (135) is fastened by penetrating the first clamp (122). When the second clamp (123) is in contact with the moving shaft (110), the end of the push bolt (135) may come into contact with the second clamp (123).

[0055] When the above push bolt (135) is tightened, the push bolt (135) moves toward the second clamp (123) and pushes the second clamp (123) to separate the second clamp (123) from the moving axis (110). (See Fig. 7)

[0056] In addition, when the push bolt (135) is released, the push bolt (135) moves in the opposite direction to the direction in which the second clamp (123) is pushed, and the second clamp (123) can come into contact with the moving shaft (110) by the elastic force of the coil spring (124).

[0057] In a case where the clamp (121) cannot be released from fixation with the push pin (131) due to an abnormality in the first moving part (132), the clamp (121) can be released from fixation using the push bolt (135). Therefore, even if there is an abnormality in the first moving part (132), the bracket (120) can be moved by releasing the fixation of the clamp (121).

[0058] The first sensors (140) are respectively provided and fixed to the upper portion of each bracket (120) when each bracket (120) is positioned at the origin. For example, the first sensors (140) may be mounted on a fixing member that fixes the first moving unit (130).

[0059] The number of the first sensors (140) is the same as the number of the brackets (120). An example of the first sensors (140) may be a proximity sensor. Using the first sensors (140), the return to the origin of the brackets (120) can be accurately confirmed.

[0060] The above second sensor (150) is provided so as to be able to move in the left and right directions.

[0061] For example, the second sensor (150) may be mounted on a member that moves in the left-right direction in the first moving unit (130). In this case, the second sensor (150) may move in the left-right direction while the first moving unit (130) does not move the brackets (120).

[0062] In contrast, the second sensor (150) is mounted on a separate moving part and can move in the left and right directions by the separate moving part.

[0063] The second sensor (150) can detect a protrusion (120a) protruding from each bracket (120) while moving along the left and right directions, or can detect a specific part of each bracket (120) to confirm the current position of each bracket (120).

[0064] The second sensor (150) may be an optical sensor equipped with a light emitting portion and a light receiving portion. For example, the second sensor (150) may be a horseshoe-shaped optical sensor.

[0065] The second moving unit (160) is provided to support the moving shaft (110), the brackets (120) and the first moving unit (130), and moves the moving shaft (110), the brackets (120) and the first moving unit (130) in the up and down direction.

[0066] The second moving unit (160) includes a pair of fixed plates (161), and the fixed plates (161) can support the moving shaft (110), the guide member (125) of the brackets (120), and both ends of the first moving unit (130), respectively.

[0067] The second moving unit (160) can move the fixed plates (161) in the vertical direction. Accordingly, the box adhesive accessories (10) can be moved adjacent to or away from the packaging box by the second moving unit (160).

[0068] When the above box adhesive accessories (10) are adjacent to the packaging box, the adhesive can be sprayed from the box adhesive accessories (10) onto the packaging box.

[0069] When the spraying of the adhesive is completed in the box adhesive accessories (10), the box adhesive accessories (10) can be moved away from the packaging box by the second moving unit (160).

[0070] Meanwhile, examples of the second moving unit (160) include a pneumatic cylinder and a pump, a linear motor and an LM guide, a rotary motor and a ball screw, a rotary motor, a pulley and a belt, a rotary motor and a gear, a rotary motor, a gear and a chain, etc.

[0071] The second moving unit (160) may include third sensors (162) that detect the up and down movement of any one of the moving axis (110), the guide member (125) of the brackets (120), and the first moving unit (130).

[0072] The third sensors (162) may be provided at regular intervals along the vertical direction on the fixing member that fixes the second moving unit (160). An example of the third sensors (162) may be a proximity sensor.

[0073] The third sensors (162) can detect the height of any one of the moving shaft (110), the guide member (125), and the first moving unit (130), or the height of the fixed plates (161). The height of the box adhesive accessories (10) fixed to the brackets (120) can be confirmed using the detection results detected by the third sensors (162). Therefore, the height of the box adhesive accessories (10) can be accurately confirmed using the third sensors (162).

[0074] The above moving axis (110), the guide member (125) of the above brackets (120) and both ends of the first moving unit (130) can each be supported.

[0075] The above input unit (170) inputs location information regarding the spraying position of the box adhesive accessories (10) according to the type of the packaging box. The location information may be manually input by the user or automatically input from a drawing file of the packaging box including the location information.

[0076] For example, the input unit (170) may include a key pad or touch screen that allows the user to input manually.

[0077] As another example, the input unit (170) may be a network terminal capable of transmitting the drawing file via the Internet or a network, or capable of connecting to a storage medium such as a USB.

[0078] In addition, the input unit (170) can store the location information according to the type of the input packaging box, and can retrieve the stored location information as needed.

[0079] The control unit (180) controls the first moving unit (130) and the second moving unit (160) so that the box adhesive accessories (10) move to the spraying position according to the position information of the input unit (170). At this time, the control unit (180) accurately confirms the current position of the brackets (120) through the first sensor units (140) and the second sensor (150), and controls the first moving unit (130) and the second moving unit (160) to move the brackets (120) so that the box adhesive accessories (10) move to the spraying position based on the current position.

[0080] Accordingly, the box adhesive accessories (10) can be accurately moved to the spraying position to spray the adhesive, thereby improving the quality of the packaging box being manufactured.

[0081] The above control unit (180) is shown as being provided integrally with the input unit (170), but may also be provided separately from the input unit (170).

[0082]
