Description

Technical Field

[0001] This utility model relates to the production and manufacturing of paper boxes. Background Technology

[0002] Labels need to be affixed to cardboard boxes during production. There are many types of labels, such as release labels (which include the label face material and release material). The label face material (which is a trademark or graphic label) has a release material (such as release paper or release film) on its bottom side. Currently, the release material is manually peeled off before the label face material is affixed to the cardboard box (such as its finished or semi-finished product). This method is inefficient, results in poor uniformity of placement, and makes it difficult to guarantee a smooth finish. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a cardboard box labeling device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a paper box release label applicator, comprising a supply table for feeding labels one by one, a peeling and transfer assembly mechanism, and a placement position for feeding paper box materials, characterized in that: the supply table has a supply end for feeding labels into place, the peeling and transfer assembly mechanism has a peeling station for separating the release layer from the label surface material, the peeling station is configured at the supply end, and the peeling and transfer assembly mechanism further includes a transfer nozzle for lifting, placing, suction and assembling the label surface material, the transfer nozzle being connected between the supply end and the placement position.

[0005] The following optimizations or supplementary explanations can be made to the above technical solutions.

[0006] For example, the peeling and transfer assembly mechanism also includes a fixing component for fixing the release layer, which is located at the peeling station.

[0007] Specifically, for example: the fixing component adopts a lower suction nozzle device or an upper and lower clamping edge device; the fixing component and the transfer air nozzle work together to peel off the release layer.

[0008] For example, the feeding platform includes a left feeding rail and a right feeding rail. The upper side between the left and right feeding rails forms a feeding path for the label, and the end of the feeding path is the feeding end. The feeding end is also equipped with a positioning limit component to limit the label position.

[0009] For example, the positioning limit component is set on the left material support rail, and the right material support rail has a notch at the supply positioning end. A support edge step block is set at the notch to support the right edge of the label material. The support edge step block is connected to the material support of the right material support rail. The front end and / or rear end of the support edge step block are also provided with a fixing component for fixing the release layer. The fixing component is a pre-peeling clamp for pre-peeling the end of the release layer. The pre-peeling clamp includes a clamp opening and closing drive component. The pre-peeling clamp is also connected to a pre-peeling drive component for pre-peeling operation.

[0010] For example, the pre-peeling fixture also includes an upper jaw and a lower jaw. The upper jaw and the lower jaw open and close through the fixture opening and closing drive component. The upper jaw and the lower jaw separate to feed the label in. The upper jaw and the lower jaw close together to clamp the protruding edge of the release layer that extends beyond the outline of the label material. The pre-peeling drive component drives the pre-peeling fixture to move obliquely back and forth.

[0011] For example, the feeding platform also includes a pusher and transfer plate, which is set in accordance with the transfer path and is configured between the left and right support rails. The pusher and transfer plate has a loading section and a pushing section. The loading section is located on the pushing side of the pushing section and is a loading plane. The pushing section is a pushing boss, the height of which is less than or equal to the label thickness. The pushing and retracting side of the pusher and transfer plate has a label lifting section. Above the left and right support rails is a material magazine for stacking labels. The magazine has a front stop vertical bar and a rear stop vertical bar. The lower end of the front stop vertical bar has an output space for single label output. The output space is located above the loading section, the left support rail, and the right support rail. The pushing boss has a forward-backward oriented clearance groove, and the lower end of the rear stop vertical bar has a blocking section corresponding to the clearance groove.

[0012] In addition, the left feed rail is equipped with a side pusher at the feed end for shifting the label to the right.

[0013] For example, the air delivery nozzle will pick up, lift, move, lower, and release the label material at the supply end onto the cardboard box material.

[0014] For example, the air transfer nozzle is located at the lower end of the lifting hollow tube. The lifting hollow tube is connected to the slide plate through the lifting guide pair. The slide plate moves back and forth and is located above the lifting hollow tube. The slide plate is equipped with a lifting drive motor, which is driven by a lead screw. The lead screw is vertically arranged and extends into the lifting hollow tube. The lead screw is driven by a nut, which is fixedly connected to the lifting hollow tube. The nut is located at the upper end of the lifting hollow tube. The upper end of the lifting hollow tube is equipped with a mounting plate for assembling and connecting the nut and the lifting guide pair.

[0015] In addition, the cardboard box labeling device is also equipped with a cardboard box body conveying mechanism, which includes a horizontal box body conveyor belt. The placement position is set in the cardboard box body conveying mechanism. The horizontal box body conveyor belt has a cardboard box material labeling placement station. The placement position is also equipped with a box body clamping and positioning device, which includes left and right clamping components. The placement position is also equipped with a box body bottom pushing and positioning device, which includes a bottom pushing movable component that pushes the bottom plate of the corresponding horizontal box body towards the box opening. The installation position is also equipped with a box opening limiting and blocking component set on the opposite side of the bottom pushing movable component.

[0016] The beneficial effects of this utility model are that the paper box release label applicator can peel off the release layer (such as release paper or release film) from the bottom surface of the label (including the label face material and release material), then pick up the label face material, transfer and transport it, and place it on the paper box material to complete the labeling, thereby improving labeling efficiency and enhancing the uniformity of labeling position. It can also be used in the downstream processes of paper box forming machines, seamlessly integrated into the paper box (such as wine box) forming and manufacturing production line.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] Referring to the accompanying drawings, the paper box release label applicator in this embodiment includes a delivery platform 1, a peeling and transfer assembly mechanism 2, and a placement position 3. Among them, placement position 3 is for placing paper box materials. Placement position 3 is the position for placing paper box materials (such as paper box body, etc.) so that the label face material can be applied to the paper box material later. Among them, the supply plate 1 is used to supply labels one by one. The supply plate 1 cooperates to supply and output labels (including label face material and release material) one by one. The supply plate 1 has a supply end 10 for label supply in place. When the label is in the supply end 10, it is in the supply output state. The peeling and transfer assembly mechanism 2 has a peeling station for peeling off the release layer. At the peeling station, the release layer separates from the label material, thus achieving peeling. The peeling station is located at the supply end 10 so that the peeling and transfer assembly mechanism 2 can cooperate at the supply end 10 to peel off the release layer (such as release paper or release film) from the bottom surface of the label material, so that the label material is in a state that can be used for adhesion. The peeling and transfer assembly mechanism 2 also includes a transfer nozzle 20, which is used for lifting, placing, and assembling the label material. The transfer nozzle 20 is connected between the supply end 10 and the placement position 3. The transfer nozzle 20 is used to pick up, lift, and transport the label material at the supply end 10 to the placement position 3, and place the label material on the cardboard box material (such as the cardboard box body) waiting to be labeled at the placement position 3 to complete the labeling.

[0033] This cardboard box release label applicator can peel off the release layer (such as release paper or release film) from the bottom of the label (including the label face material and release material), then pick up the label face material, transfer and transport it, and place it on the cardboard box material to complete the labeling. This improves labeling efficiency and enhances the uniformity of label placement. It can also be used in the downstream processes of cardboard box forming machines, seamlessly integrated into the cardboard box (such as wine boxes) forming production line.

[0034] Based on the above embodiments, the following optimizations or further explanations can be made.

[0035] For example, the peeling and transfer assembly mechanism 2 also includes a fixing component 4, which is used to fix the release layer. The fixing component 4 is arranged at the peeling station and is used to fix the release layer of the label so that the release layer can be separated from the upper label material and peeled off.

[0036] For example, the fixing component 4 can be a lower suction nozzle or an upper and lower clamping device; the lower suction nozzle is used to suck up the release layer from below and fix it in place. The upper and lower clamping device is used to clamp the edge of the release layer and fix it in place, and can be used for areas where the release layer has protruding edges that extend beyond the outline of the label material. The transfer nozzle 20 will also work with the fixing component 4 to peel the release layer away from the label material. After the fixing component 4 has fixed the release layer, the transfer nozzle 20 can suck up and lift the label material from above, thus separating the label material from the release layer and achieving peeling.

[0037] For example, the feeding platform 1 includes a left feeding rail 11 and a right feeding rail 12. The upper side between the left feeding rail 11 and the right feeding rail 12 is the feeding path for label transfer, and the end of the feeding path is the feeding end 10. The label can be supported and fed out by the left feeding rail 11 and the right feeding rail 12. The feeding end 10 is also equipped with a positioning limit component 13 (such as a limit stop) to ensure that the label is smoothly fed into position during the feeding process, and that the relative positions of each label are uniform when it is fed into position.

[0038] For example, the positioning limit component 13 can be set on the left material support rail 11, and the right material support rail 12 has a gap at the supply end 10. For example, the right material support rail 12 is arranged to be interrupted at the supply end 10 to form a gap. A support edge step block 14 is set at the gap to support the right edge of the label material. The right edge of the label material partially extends beyond the release layer. The support edge step block 14 is connected to the right material support rail 12, which can make the connection smoother and more stable during the label supply and transfer process. The right edge of the label material partially extends beyond the release layer. When the release layer is delivered to the end 10, it is supported by the stepped portion 141 of the edge support block 14 (which can be flush with the right material support rail 12 for material support). The stepped portion 141 can be an extremely narrow step that can support the right edge of the label paper and help to peel it off. The front end and / or rear end of the edge support block 14 are also provided with fixing components 4 (for fixing the release layer). For example, the fixing component 4 can be a pre-peeling clamp 40 for pre-peeling the end of the release layer. The end of the release layer has a protruding edge position that exceeds the outline of the label material. The pre-peeling clamp 40 is used to clamp the release layer. The pre-peeling clamp 40 includes a clamp opening and closing drive component 41 (such as a cylinder or motor) to control the pre-peeling clamp 40 to clamp and release the end of the release layer. For example, the pre-peeling clamp 40 may use a pneumatic finger structure. The pre-peeling clamp 40 is also connected to a pre-peeling drive component (such as a cylinder or motor) to drive the pre-peeling clamp 40 to perform the pre-peeling operation. For example, a local area at the end of the release layer has a protruding edge that extends beyond the outline of the label material, such as a local area on the right edge of the label material. The right edge of the label material is partially supported by the stepped portion 141 of the support step block 14, which is located relative to the release layer. The pre-peeling clamp 40 can clamp the protruding edge of the release layer at the supply end 10. The pre-peeling drive component drives the pre-peeling clamp 40 to descend, which can peel the release layer end from the label material. In this structure, after the end is pre-peeled and separated, it is easier, smoother, and with less resistance to completely peel the release layer from the label material in the subsequent process (with the cooperation of the transfer air nozzle 20). The label material is less likely to shift or deform.

[0039] For example, the pre-peeling clamp 40 also includes an upper clamp and a lower clamp. The upper and lower clamps are opened and closed by the clamp opening and closing drive component 41. Two pairs of upper and lower clamps can be arranged in front and behind, and a support edge step block 14 is arranged between the two pairs. The upper and lower clamps are separated to feed the label in. The upper and lower clamps are closed to clamp the protruding edge of the release layer that exceeds the outline of the label material. The pre-peeling drive component drives the pre-peeling clamp 40 to move obliquely back and forth to stably peel off the end.

[0040] Labels can be manually placed on the feeding platform 1, or a robotic arm (industrial robot) with a suction nozzle can be used to place the labels stacked on the lifting pallet one by one onto the feeding platform 1 so that the feeding platform 1 can feed the labels one by one. Alternatively, a material storage hopper 6 for stacking labels can be provided above the left feeding rail 11 and the right feeding rail 12 to cooperate with the feeding.

[0041] For example, the feeding platform 1 also includes a pushing and transferring plate 5, which is set in accordance with the transfer path and is configured between the left material support rail 11 and the right material support rail 12. The bottom of the pushing and transferring plate 5 is mounted on a movable support 55 that moves back and forth. The movable support 55 is configured to run on the guide rail and is driven to move back and forth by a motor with a synchronous belt structure (or driven by a cylinder). The pushing and transferring plate pushes the labels in the feeding platform 1 one by one and pushes the labels to the feeding end 10.

[0042] For example, the pusher plate 5 has a loading part 51 and a pushing part 52. The loading part 51 is located on the pushing side of the pushing part 52. The loading part 51 can be used to support the label, and the label can be placed on it to cooperate with the pushing. For example, the loading part 51 can be set as a loading plane for the label to be placed stably. For example, the pushing part 52 can be set as a pushing boss, and the pushing part 52 cooperates to push the label on one side during the process of the pusher plate 5 transferring the label. Furthermore, the height of the pusher boss is less than or equal to the label thickness, which allows for the smooth pushing and moving of single labels. It is compatible with structures where a material magazine 6 is located directly above the left and right material rails 11 and 12. While smoothly pushing and moving single labels out, it does not affect other labels stacked above. In addition, the pusher plate 5 has a label lifting part 53 (such as a label lifting ramp) on its push-back side. The label lifting part 53 can lift the labels located on the left and right material rails 11 and 12 in the material magazine 6 during the pusher plate 5's retraction process. The pusher plate can retract smoothly, and when it retracts to the correct position, its loading part 51 can be located directly below the material magazine 6, making it convenient for new labels to fall on it and be pushed. For example, the lower port of the material storage 6 is located above the left and right material support rails 11 and 12. The material storage 6 has a front baffle vertical bar 61 and a rear baffle vertical bar 62. It can also have left and right side plates 63. The lower end of the front baffle vertical bar 61 has an output space for single label output. The output space is located above the material loading section 51, the left material support rail 11, and the right material support rail 12, so that the bottom layer of labels in the material storage 6 can be pushed out. The pusher protrusion is provided with a front-to-back clearance groove 54. The lower end of the rear baffle vertical bar 62 has a baffle part corresponding to the clearance groove 54. During the retraction of the pusher conveyor plate 5, the baffle part passes through the clearance groove 54. The pusher conveyor plate 5 can not only retract smoothly, but the baffle part can also block the labels in the material storage 6. The label lifting part 53 can smoothly lift the labels in the material storage 6.

[0043] Furthermore, the left material guide rail 11 is equipped with a side pusher 15 at the supply end 10 for moving the label to the right. The side pusher 15 can be driven to move left and right by a cylinder or motor, which works in conjunction with the rightward movement of the label and the reset of the side pusher 15.

[0044] For example, the air transfer nozzle 20 will pick up, lift, move, lower and release the label material after the release layer has been peeled off at the 10 supplying end onto the cardboard box material.

[0045] The air transfer nozzle 20 can be moved and operated by a robotic arm (such as an industrial robot). Alternatively, the air transfer nozzle 20 can be positioned at the lower end of the lifting hollow tube 21. The lifting hollow tube 21 is connected to the slide plate 22 via a lifting guide pair 27 (such as a paired guide post and guide sleeve). The slide plate 22 moves back and forth, driven by a motor through a synchronous belt drive structure. The slide plate 22 can be mounted on a slide rail. The lifting hollow tube 21 can move vertically relative to the slide plate 22, guided by the lifting guide pair 27. The slide plate 22 is located above the lifting hollow tube 21 and is equipped with a lifting drive motor 23. A lead screw 24 is connected, which is vertically positioned and extends into the lifting hollow tube 21. The lead screw 24 is connected to a nut 25 (such as a threaded sleeve with a threaded hole). The lifting drive motor 23 drives the lead screw 24 to rotate (switching between forward and reverse directions). The lead screw 24 drives the nut 25, which is fixedly connected to the lifting hollow tube 21, thereby enabling the lifting hollow tube 21 to move up and down. The nut 25 is located at the upper end of the lifting hollow tube 21. An mounting plate 26 is provided at the upper end of the lifting hollow tube 21 for the assembly and connection of the nut 25 and the lifting guide pair 27, which can make the lead screw 24 and its mating structure more compactly hidden inside the lifting hollow tube 21. The lower end of the lifting hollow tube 21 can also be provided with an air passage structure consisting of an upper cover plate 28 and a lower cover plate 29. An air passage structure such as an air groove can be provided between the upper cover plate 28 and the lower cover plate 29 so that the air nozzle body of the transfer air nozzle 20 can be installed on it, making it easy to connect to an external air source structure. An air inlet can be provided on the upper cover plate 28 or the lower cover plate 29.

[0046] The cardboard box labeling device is also equipped with a cardboard box body conveying mechanism 7, which is used to transport cardboard box materials (such as the box body). The placement position 3 is set in the cardboard box body conveying mechanism 7, and the cardboard box body conveying mechanism 7 directly transports the cardboard box materials (such as the box body) to the placement position 3 to wait for labeling. For example, the cardboard box body conveying mechanism 7 includes a horizontal box body conveyor belt 70, wherein the horizontal box body conveyor belt 70 has a cardboard box material labeling placement station, and the placement position 3 is arranged at the cardboard box material labeling placement station. The horizontal box body conveyor belt 70 directly transports the horizontally positioned cardboard box body to the placement position 3 at the cardboard box material labeling placement station to wait for labeling.

[0047] In addition, the placement position 3 is also equipped with a box clamping and positioning device 71. The box clamping and positioning device 71 includes left and right clamping components, which are used to clamp and position the (horizontal) paper box body conveyed to the placement position 3 from the left and right sides. This ensures that the relative position of the paper box body is more uniform when labeling, and also prevents the paper box body from shifting during labeling. The left and right clamping of the paper box can also support the paper box to complete the labeling. For example, the left and right clamping components are respectively set on a slide that can be adjusted left and right. A rotating shaft 75 is set on the slide, and a swing arm 76 is set on the rotating shaft 75. The swing arm 76 is driven by a cylinder to swing back and forth, thereby driving the rotating shaft 75 to rotate forward and reverse on the slide. A rod 73 is set on the rotating shaft 75 to cooperate in clamping the paper box. The mounting position 3 is also equipped with a box body pushing and correcting device 72. This device includes a pushing component 77 that pushes the bottom plate of the horizontal box towards the box opening. The pushing component 77 (e.g., driven by a cylinder or motor) can push the box towards the box opening. The mounting position also has a box opening limiting stop 74 located on the opposite side of the pushing component 77. The box opening limiting stop 74 helps to limit the box opening, allowing the pushing component 77 to smoothly correct the cardboard box and ensure a more uniform relative position during labeling. The box body clamping and positioning device 71 and the box body pushing and correcting device 72 work together to correct the position of the cardboard box, ensuring a relatively accurate and uniform labeling position. The pushing component 77 can be a push plate, and the push plate may even have a suction function to hold the cardboard box in place before pushing it, and then release the suction afterward.
