Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of adhesive lines, in particular to a paper tray automatic adhesive line. BACKGROUND

[0002] Paper trays are new unitized logistics appliances made of paper laminated boards or corrugated paper and other materials through a series of processing and bonding. They are gradually widely used in the logistics operation chain due to their light weight, high strength, good toughness, non-deformation, pressure resistance, impact resistance, shock resistance, heat insulation, sound insulation and other characteristics. Figure 2 A paper tray (see Figure 2 ) generally consists of a bearing panel, a foot block (longitudinal beam or cushion block), and a bottom plate. In the existing paper tray production process, the foot plate is usually pre-fabricated into a foot block, the panel is edge-wrapped, and then the foot block is bonded with the bottom plate and the panel in sequence by manual gluing to form a finished paper tray. The production efficiency is relatively low, the labor intensity is high, and the bonding between the bottom plate, the panel and the foot block is not sufficient, which reduces the bonding strength of the paper tray, is not conducive to the circulation of the paper tray, and causes resource waste. Therefore, it is necessary to develop a paper tray automatic adhesive line to realize automatic feeding and gluing of the bottom plate, automatic feeding and forming of the foot plate, automatic gluing of the foot block and the bottom plate, automatic feeding and gluing of the panel and the foot block, improve the production efficiency and quality of the paper tray.

The bottom plate feeding and gluing machine comprises a first rack, a first conveying assembly, a first sliding assembly, a first linear module, a first positioning and sucking assembly, and a first gluing assembly. The first conveying assembly is fixedly arranged in the first rack and is used for conveying the bottom plates to the foot block bottom plate bonding machine. The first sliding assembly is fixedly arranged at the rear end of the first rack and is above the first conveying assembly. The first sliding assembly is used for mounting the first linear module and sliding the first positioning and sucking assembly to the first conveying assembly. The first linear module is vertically arranged between the first sliding assembly and the first positioning and sucking assembly. The sliding seat of the first linear module is fixedly connected with the first sliding assembly, and the profile of the first linear module is fixedly connected with the first positioning and sucking assembly.

The first positioning and sucking assembly is arranged at the rear end of the first rack. The initial position of the first positioning and sucking assembly is at the lower end of the first positioning and sucking assembly, and the highest point of the first positioning and sucking assembly is towards the bottom plate stack. The first positioning and sucking assembly is used for arranging and positioning the bottom plates. After the bottom plates are sucked, the first positioning and sucking assembly is slid forward to the position and then is lowered to place the bottom plates on the first conveying assembly under the cooperation of the first linear module and the first sliding assembly. The first positioning and sucking assembly comprises a landing gear, a fixing frame, a sliding rod, a sliding plate, an arrangement column, a sucking disc, a servo motor, a three-fold movable joint, a vertical seat, and a photoelectric sensor.

The three-fold movable joint is in an extended state at the initial time. The vertical seat is fixedly arranged on the fixing frame. The photoelectric sensor is fixedly arranged on the left and right ends of one side. When the bottom plate of the surface layer of the bottom plate stack is between the photoelectric sensor, the first linear module stops working. Then, the servo motor is started and is positively rotated to drive the three-fold movable joint to contract. After the arrangement and positioning of the bottom plate are completed, the servo motor is stopped. Then, the sucking disc sucks the bottom plate. Subsequently, the bottom plate is lifted, moved forward, and placed downward under the cooperation of the first linear module and the first sliding assembly. The first gluing assembly is fixedly arranged at the front end of the first rack. The gluing end of the first gluing assembly faces the paper tray bottom plate downward and is above the front end of the first conveying assembly. The first gluing assembly is used for gluing the foot block area on the surface of the paper tray bottom plate.

[0006] The foot-shaped molding and framing machine (its specific structure and principle will be described separately) applies glue to the foot plates along the foot plate conveying direction and rotates them to form square foot-shaped blocks. After framing, the blocks are conveyed to the corresponding side of the foot-shaped block base plate bonding machine. The machine includes a second frame, a second conveying assembly, a second sliding assembly, a second linear module, a suction assembly, a second gluing assembly, a rotational molding and transfer assembly, and a framing assembly.

The second sliding assembly is horizontally fixedly installed on the second frame and above the second conveying assembly. The suction assembly, driven by the second linear module, slides above the foot plate stack and the second conveying assembly. The second linear module is vertically positioned between the second sliding assembly and the suction assembly, with its slide block fixedly connected to the second sliding assembly. Its profile is connected to the suction assembly. The components are fixedly connected and used to drive the suction assembly to move up and down reciprocally. The suction assembly is located on the outside of the second frame, with its initial lower end facing the foot plate stack and at its highest point. It is used to suction the bottom plate and, with the cooperation of the second linear module and the second sliding assembly, places the foot plate on the second conveying assembly. The second gluing assembly is longitudinally arranged on the second frame and above the inner side of the second conveying assembly. It is used to apply glue to the foot plate to facilitate the bonding and shaping of the foot plate during the folding process along the crease. The rotary forming and transfer assembly is fixedly installed in the second frame and is connected to the second conveying assembly and the fidelity assembly. It is used to rotate and shape the foot plate along the crease into a square foot block and then transport it to the fidelity assembly. The fidelity assembly is horizontally fixedly installed on the second frame. It is used to elastically compress and fidelity the glued foot block from both the top and bottom sides and further solidify the glue during the fidelity process to promote the shaping of the foot block.

It includes a third frame, a third conveying component, a double sliding component, and a foot-shaped base plate picking component. The third frame is set between a pair of second frames and directly in front of the first frame.

The two pairs of foot-shaped base plate picking components are slidably connected to the corresponding double sliding components. Their initial position is at the highest point and directly above the inner end of the fidelity components on the corresponding sides. They are used to pick up the foot-shaped base plates from the fidelity components on the corresponding sides and, with the cooperation of the double sliding components, place the foot-shaped base plates on the base plate.

[0008] The first conveyor is used for conveying the foot block and bottom plate bonding body to the panel feeding bonding machine and further solidifying the glue during the conveying process to firmly bond the foot block and bottom plate bonding body, comprising a fourth rack and a fourth conveying assembly.

[0009] The panel feeding bonding machine is used for sucking the panel from the panel stack and bonding it on the foot block and bottom plate bonding body, comprising a fifth rack, a supporting assembly, a third glue feeding assembly, a fifth conveying assembly, a re-pressing assembly, a second positioning and sucking assembly, a third sliding assembly and a third linear module. The fifth rack is arranged in front of the fourth rack. The supporting assembly is slidingly arranged below the fifth rack and fixed on the fifth rack during the panel bonding to support the foot block and bottom plate bonding body and provide a stable working platform for the panel bonding and protect the third sliding assembly during the re-pressing of the panel bonding. The third glue feeding assembly is transversely arranged at the rear end of the fifth rack and above the rear end of the fifth conveying assembly to feed glue on the upper surface of the foot block when the foot block and bottom plate bonding body is conveyed from the fourth conveying assembly to the fifth conveying assembly. The fifth conveying assembly is longitudinally arranged in the fifth rack and connected with the fourth conveying assembly and between the supporting assembly and the third sliding assembly to convey and position the foot block and bottom plate bonding body directly below the third sliding assembly and convey the finished product paper tray to the sixth conveying assembly after the panel bonding. The re-pressing assembly is arranged in the fifth rack and initially positioned at the highest point and above the fifth conveying assembly to extend downward and press on the panel after the panel is placed on the foot block and bottom plate bonding body to fully bond the panel and the foot block. The second positioning and sucking assembly is arranged on one side of the fifth rack and has the same structure and function as the first positioning and sucking assembly, which will not be described again. The second positioning and sucking assembly is initially positioned at the highest point and above the panel stack to arrange and suck the panel downward. The third sliding assembly is transversely fixedly arranged on the fifth rack and above the re-pressing assembly. The third linear module drives the second positioning and sucking assembly to reciprocate between the panel stack and the foot block and bottom plate bonding body through the third sliding assembly. The third linear module is vertically arranged between the second positioning and sucking assembly and the third sliding assembly. The slide table of the third linear module is fixedly connected with the third sliding assembly and the profile of the third linear module is fixedly connected with the second positioning and sucking assembly to drive the second positioning and sucking assembly to reciprocate between the highest point and the lowest point.

[0010] The second conveyor, used to transport paper pallets output from the fifth conveying assembly to the lower palletizing area, includes a sixth frame and a sixth conveying assembly. The sixth frame is located directly in front of the fifth frame, and the sixth conveying assembly is longitudinally fixed in the sixth frame and connected to the fifth conveying assembly.

[0011] Furthermore, this invention also provides a feeding and bonding method for an automatic paper pallet bonding line, comprising the following steps:

[0012] S1 Automatic Base Plate Feeding and Gluing: After the base plate stack is placed at the rear end of the first frame, the first linear module rotates forward, driving the first positioning and suction component to descend to the base plate stack, arranging and positioning the surface base plate, and adsorbing it. Then, the first linear module reverses, driving the first positioning and suction component to rise, so that the adsorbed base plate is between the first conveying component and the first sliding component. Then, the first sliding component, through the first linear module, drives the first positioning and suction component to slide forward to directly above the first conveying component, placing the base plate on the first conveying component. Immediately afterwards, the first conveying component conveys the base plate forward. When the front end of the base plate just passes directly below the first gluing component, the first gluing component applies glue to the base plate until the rear end of the base plate passes directly below the first gluing component.

[0013] S2 Automatic Footboard Feeding and Folding for Fidelity (Synchronized with S1): After the footboard stack is placed outside the second frame, the second linear module rotates forward, driving the suction component to descend and pick up the footboard from the stack. Then, the second linear module reverses, and the suction component drives the footboard to rise above the outside of the second conveying component. The second sliding component then conveys the footboard directly above the second conveying component via the second linear module and suction component, and places it on the second conveying component. The second conveying component then conveys the footboard to the rotary forming transfer component. When passing through the second gluing component, the footboard is glued. After the glued footboard enters the rotary forming transfer component, it is folded and glued layer by layer from the inside to the outside along the crease to form a square footboard, and then enters the fidelity component.

[0014] S3 Foot Block Bonding to Base Plate: After the base plate is completely conveyed from the first conveying component to the third conveying component, the third conveying component stops working. At the same time, two pairs of foot block suction components extend downwards to pick up two foot blocks from the corresponding side of the fidelity component and then retract upwards. Then, a pair of double sliding components drive the corresponding pair of foot block suction components to slide towards each other to directly above the glue line of the base plate. Then, the two pairs of foot block suction components extend downwards again to press the foot blocks down and place them on the base plate along the corresponding glue line, thus completing the bonding of the foot blocks to the base plate.

[0015] S4 panel automatic feeding and bonding: when the foot block and the bottom plate bonding body are completely conveyed to the fifth conveying assembly by the fourth conveying assembly, the fifth conveying assembly pauses, at the same time, the second positioning and sucking assembly arranges and sucks the panel on the panel stack downward, then the panel is lifted to the highest point under the action of the third linear module, then the third sliding assembly drives the second positioning and sucking assembly to slide to the top of the foot block and the bottom plate bonding body through the third linear module, then the second positioning and sucking assembly places the panel on the foot block downward, and then the supporting assembly and the re-pressing assembly move upward and downward respectively to the bottom plate and the panel, and the bonding of the paper tray is completed;

[0016] S5 paper tray finished product output: after the bonding and re-pressing of the paper tray are completed, the supporting assembly and the re-pressing assembly reset downward and upward respectively, and are separated from the bottom plate and the panel, the fifth conveying assembly is started, the paper tray is conveyed to the sixth conveying assembly, and then is conveyed to the stacking area by the sixth conveying assembly.

[0035] Referring to Figure 5The foot-shaped molding and framing machine 2 (its specific structure and principle will be described separately) applies glue to the foot plates along the foot plate conveying direction and rotates them to form square foot-shaped blocks.

By setting the foot block forming fidelity assembly, the forming and transferring assembly 27 can be achieved. In the real machine 2, the second linear module 24 rotates forward, driving the suction component 25 downward to pick up the foot plate from the foot plate stack. Then, the second linear module 24 reverses, and the suction component 25 drives the foot plate to rise to the outside of the second conveying component 22.

It includes a third frame 31, a third conveying assembly 32, a double-sliding assembly 33, and a foot-foot suction assembly 34. The third frame 31 is positioned between a pair of second frames 21 and directly in front of the first frame 11. The third conveying assembly 32 is longitudinally fixed in the third frame 31 and connected to the first conveying assembly 12. A pair of double-sliding assemblies 33 are transversely fixed on the third frame 31 and respectively connected to the corresponding fidelity assembly 28 on each side, used to drive the foot-foot suction assembly 34 to slide back and forth. The two pairs of foot-foot suction assemblies 34 are slidably connected to the corresponding double-sliding assemblies 33, with their initial position at the highest point. The foot block is located directly above the inner end of the corresponding fidelity component 28 on the corresponding side. It is used to pick up the foot block from the corresponding fidelity component 28 and place the foot block on the base plate with the cooperation of the double sliding component 33.

7. The automatic bonding line for paper pallets according to claim 6, wherein the bonding method comprises the following steps: S1 Automatic Feeding and Gluing of Base Plates: When the base plate stack is placed at the rear end of the first frame (11), the first linear module (14) rotates forward, driving the first positioning suction component (15) down to the base plate stack, arranging and positioning the surface base plate and adsorbing it. Then the first linear module (14) reverses, driving the first positioning suction component (15) up, so that the adsorbed base plate is between the first conveying component (12) and the first sliding component (13). Then the first sliding component (13) drives the first positioning suction component (15) forward through the first linear module (14) to slide directly above the first conveying component (12), placing the base plate on the first conveying component (12). Then the first conveying component (12) conveys the base plate forward. When the front end of the base plate just passes directly below the first glue component (16), the first glue component (16) glues the base plate until the rear end of the base plate passes directly below the first glue component (16). S2 Automatic Footboard Feeding and Folding for Fidelity: After the footboard stack is placed outside the second frame (21), the second linear module (24) rotates forward, driving the suction component (25) to descend and suck up the footboard from the stack. Then, the second linear module (24) reverses, and the suction component (25) drives the footboard to rise above the outside of the second conveying component (22). The second sliding component (23) then transports the footboard to the top of the second conveying component (22) via the second linear module (24) and the suction component (25), and places it on the second conveying component (22). The second conveying component (22) then transports the footboard to the rotary forming transfer component (27). When passing through the second gluing component (26), the footboard is glued. After the glued footboard enters the rotary forming transfer component (27), the footboard is folded and glued layer by layer from the inside to the outside along the crease to form a square footboard, and then enters the fidelity component (28). S3 Foot block and base plate bonding: After the base plate is completely conveyed from the first conveying component (12) to the third conveying component (32), the third conveying component (32) stops working. At the same time, the two pairs of foot block suction components (34) extend downwards respectively to suck up two foot blocks from the corresponding side of the fidelity component (28) and then retract upwards. Then, a pair of double sliding components (33) respectively drive the corresponding pair of foot block suction components (34) to slide towards each other to the top of the corresponding glue line of the base plate. Then, the two pairs of foot block suction components (34) extend downwards again to press the foot blocks down and place them on the base plate along the corresponding glue line, thus completing the bonding of the foot block and the base plate. S4 Automatic Panel Feeding and Bonding: After the foot block and the base plate bonded body are completely conveyed to the fifth conveyor (54) by the fourth conveyor component (42), the fifth conveyor component (54) stops working. At the same time, the second positioning suction component (56) moves downward to sort the panels on the panel stack and sucks up the panels. Then, under the action of the third linear module (58), the panels are lifted to the highest point. Then, the third sliding component (57) drives the second positioning suction component (56) to slide directly above the foot block and the base plate bonded body through the third linear module (58). Then, the second positioning suction component (56) moves downward to place the panels on the foot block. Then, the supporting component (52) and the pressing component (55) simultaneously push upward and downward against the base plate and the panel respectively to complete the bonding of the paper tray. S5 Paper Pallet Finished Product Output: After the paper pallet is bonded and repressed, the supporting component (52) and the repressing component (55) simultaneously reset downwards and upwards respectively, detaching from the bottom plate and the front plate. The fifth conveying component (54) is activated to convey the paper pallet to the sixth conveying component (62), and then the sixth conveying component (62) conveys it to the palletizing area.
