Description

Technical Field

[0001] This utility model relates to paper box forming equipment, and particularly to its cardboard feeding structure. Background Technology

[0002] Connected cardboard boxes (such as connected shoe boxes) can be used to package items (such as shoes). In some usage scenarios, it is necessary to put cards, cardboard, or other items inside the connected cardboard box, or to put envelopes, red envelopes, or other paper bags inside the box for packaging other things. Currently, in use, all of the above operations are done manually, which is not only troublesome, but also results in the cards, cardboard, or paper bags (referred to as sheet materials) being placed randomly and inconsistently inside the connected cardboard box, and easily deviating from the desired placement. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a cardboard feeding mechanism for an integrated cardboard box forming equipment.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a cardboard feeding mechanism for a one-piece cardboard forming equipment, which includes a lifting feeding platform for stacking cardboard, a top cardboard rising and positioning position above the lifting feeding platform, and a cardboard transfer feeding nozzle above the lifting feeding platform, the cardboard transfer feeding nozzle being connected to the top cardboard rising and positioning position. The invention is characterized by further including a sheet assembly station for assembling sheet materials onto the top cardboard and a sheet material mounting and bonding device, the sheet assembly station being located at the top cardboard rising and positioning position, and the sheet material mounting and bonding device being connected to the sheet assembly station.

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

[0006] For example, the sheet material loading and bonding device includes a top paperboard glue spraying component, a sheet material bin, and a sheet material picking, transferring, and loading robot. The top paperboard glue spraying component is positioned above the sheet material assembly station, and the sheet material picking, transferring, and loading robot is connected between the sheet material bin and the sheet material assembly station.

[0007] The top-layer cardboard glue spraying component corresponds to the sheet assembly station; the top-layer cardboard glue spraying component includes a cardboard glue spraying gun facing the sheet assembly station; the top-layer cardboard glue spraying component sprays glue vertically from top to bottom or diagonally from top to bottom. For example, the sheet material picking, transferring, and loading robot includes a sheet material transfer and assembly suction nozzle that picks up the sheets from the sheet material bin and transfers them to the top-layer cardboard of the lifting feeding platform for assembly.

[0008] Special optimization: the sheet assembly station is located in the box cover area where the top cardboard rises and is positioned.

[0009] In addition, the lifting feeding platform includes a lifting paper support frame, which is driven by a lifting drive motor. The cardboard transfer feeding nozzle includes a lifting and translating cardboard transfer nozzle component.

[0010] For example, the sheet material hopper includes a stacking hopper, which can be vertical or inclined. The lower end of the stacking hopper is the sheet material outlet, and the edge of the outlet is equipped with sheet material retaining components. The outlet is located above the sheet material assembly station.

[0011] For example, the sheet material handling, transfer, and loading robot includes a rotary transfer arm with a sheet material transfer and assembly nozzle mounted on it. The rotary transfer arm and the sheet material transfer and assembly nozzle are located above the sheet material assembly station. The rotary transfer arm has a rotary stop for picking up materials and a rotary stop for loading. At the rotary stop for picking up materials, the sheet material transfer and assembly nozzle faces the outlet of the sheet material bin and moves forward and backward. At the rotary stop for loading, the sheet material transfer and assembly nozzle faces the sheet material assembly station below and moves up and down.

[0012] Or, to give another example, the sheet material handling and transfer robot includes a rotary switching arm, on which a sheet material transfer and assembly suction nozzle is installed. The sheet material handling and transfer robot also includes a cam swing arm and a lifting seat. The lifting seat is configured on a vertical track and is connected to a lifting power component. The lifting seat is equipped with a rotary support shaft, the rotary switching arm is connected to the rotary support shaft, and the cam swing arm is connected to a swing support shaft. The cam swing arm is equipped with a cam slot hole that cooperates to enable the rotary switching arm to perform up-and-down rotation and lifting movements. The rotary support shaft is fitted through the cam slot hole. The cam swing arm is equipped with a guide shaft that cooperates to enable the rotary switching arm to perform up-and-down rotation and lifting movements. The rotary switching arm is equipped with a guide rail that cooperates to enable the rotary switching arm to perform up-and-down rotation and lifting movements. The guide shaft is connected to the guide rail.

[0013] Further optimizations include mounting the vertical track, lifting power components, and swing support shaft on the mounting plate; using a straight guide track; rotating relative to the guide shaft; and shifting relative to the guide shaft along its track direction.

[0014] The guide rail can be a linear groove. For example, in the vertical position of the cam arm, its cam slot includes an upper vertical groove segment, a middle arc-shaped groove segment, and a lower vertical groove segment that are connected from top to bottom. The guide shaft is located on the center side of the arc-shaped groove segment. The middle arc-shaped groove segment is a circular arc-shaped groove segment that does not exceed a semicircle.

[0015] The beneficial effects of this utility model are that the cardboard feeding mechanism of the integrated cardboard box forming equipment has the function of assembling sheet material onto the unformed cardboard material, and the assembly is completed during the feeding process of the cardboard with the lifting feeding platform, without affecting or interfering with the normal forming of the subsequent cardboard box, and the efficiency is relatively high; the subsequent finished cardboard box does not need to place sheet material separately, and the sheet material is in a relatively uniform and stable position in the box body, which is more convenient and practical.

[0037] 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.

[0038] Referring to the accompanying drawings, the cardboard feeding mechanism of the integrated cardboard box forming equipment in this embodiment includes a lifting feeding platform (a mature technology, not shown in the figure). The lifting feeding platform is on which cardboard is stacked. The cardboard to be processed into an integrated cardboard box (such as an integrated shoe box) is stacked on the lifting feeding platform. The top layer cardboard is positioned at the top of the lifting feeding platform. The lifting feeding platform gradually rises to feed the stacked cardboard upwards. The top layer cardboard 80 rises to the top layer cardboard position 10 (i.e., it is in place). A cardboard transfer feeding nozzle 2 is provided above the lifting feeding platform. The cardboard transfer feeding nozzle 2 is connected to the top layer cardboard position 10. 2. The cardboard stacked on the top layer (the very top of the stack) of the lifting feeding platform is picked up and transferred to the integrated carton forming equipment for subsequent forming processing, such as the CN206678450U integrated carton forming machine. Based on this, it will be further optimized. The cardboard feeding mechanism of the integrated carton forming equipment also includes a sheet assembly station 3 for assembling sheet material 81 onto the top layer cardboard 80 and a sheet board bonding device 4. The sheet assembly station 3 is configured at the rising and positioning position 10 of the top layer cardboard. The sheet board bonding device 4 is connected to the sheet assembly station 3. At the sheet assembly station 3, the sheet material 81 (taken out) is assembled and bonded to the rising and positioning (i.e., rising into place) top layer cardboard 80 with the cooperation of the sheet board bonding device 4.

[0039] Its working principle is that a sheet assembly station 3 and a sheet loading and bonding device 4 are set directly in the cardboard feeding mechanism of the integrated cardboard box forming equipment. Before the integrated cardboard box is formed, the sheet material can be assembled directly on the cardboard during the cardboard feeding process so that the box body comes with sheet material (such as cards, cardboard, envelopes, red envelopes, etc.) after the integrated cardboard box is formed. It can be used for customized integrated shoe boxes, which is more practical and convenient.

[0040] The cardboard feeding mechanism of this integrated cardboard box forming equipment has the function of assembling sheet material onto the unformed cardboard material. The assembly is completed during the feeding process of the cardboard with the lifting feeding platform, without affecting or interfering with the normal forming of the subsequent cardboard boxes. The efficiency is also relatively high. The finished cardboard boxes do not need to have additional sheet material placed in them. The sheet material is in a relatively uniform and stable position in the box body, which is more convenient and practical.

[0041] For example, the sheet loading and bonding device 4 includes a top paperboard spraying component 5, a sheet material bin 6, and a sheet material picking, transferring, and loading robot 7.

[0042] The unit includes a sheet assembly station 3 located above the lifting feeding platform. This station is used to assemble sheet materials onto the top layer of cardboard on the lifting feeding platform, where the assembled sheet material is adhered to the rising and positioned (fully positioned) top layer of cardboard. As the cardboard stacked on the lifting feeding platform rises, the corresponding top layer of cardboard can rise and be positioned (fully positioned) at the height corresponding to the sheet assembly station 3.

[0043] The top-layer cardboard adhesive spraying component 5 is positioned above the sheet assembly station 3, allowing it to conveniently spray the adhesive for assembly onto the sheet assembly station 3. This layout is more rational. When the top-layer cardboard on the lifting feeding platform rises to the correct position (reaches the correct height) and stops at the height corresponding to the sheet assembly station 3 (i.e., the top-layer cardboard rises to the correct position 10), the top-layer cardboard adhesive spraying component 5 can spray the adhesive for assembly onto the corresponding area of ​​the top-layer cardboard at this time (at the sheet assembly station 3), waiting for the sheet to adhere to that area. This structure directly applies adhesive to the top-layer cardboard, making it more stable, convenient, faster, and more efficient, with higher adhesive spraying stability.

[0044] The sheet material bin 6 is used to store sheet materials 81 (such as red envelopes, envelopes, cards, cardboard, paper scraps, etc.). The sheet material picking, transfer and loading robot 7 is connected between the sheet material bin 6 and the sheet material assembly station 3. The sheet material picking, transfer and loading robot 7 works together to take out the sheet materials 81 from the sheet material bin 6 and transfer them to the sheet material assembly station 3 for assembly. The corresponding area of ​​the top layer cardboard 80 on the lifting feeding platform has been sprayed with glue by the top layer cardboard glue spraying component 5, so that the sheet material can be glued to the corresponding area of ​​the top layer cardboard at the sheet material assembly station 3 for adhesive bonding.

[0045] Among them, a sheet assembly station 3 is set at the top cardboard rising and positioning position 10 above the lifting feeding platform (the position for corresponding assembly). The sheet loading and bonding device 4 assists in assembling the sheet onto the top cardboard on the lifting feeding platform in advance. Then, the cardboard transfer feeding nozzle 2 assists in conveying the top cardboard with the assembled sheet to the subsequent process of the integrated carton forming equipment (the lid forming station for lid forming). This allows the sheet to be placed in the box body in advance before the integrated carton is formed, and the position of the sheet in the box body is relatively uniform and stable. During the assembly process, the top cardboard glue spraying component 5 first sprays glue onto the corresponding area of ​​the top cardboard. Then, the sheet picking and transfer loading robot 7 assists in taking out the sheet from the sheet bin 6 and transferring it to the corresponding area of ​​the top cardboard for glue bonding.

[0046] Based on the above embodiments, the following optimizations or further explanations can be made.

[0047] For example, the top-layer cardboard glue spraying component 5 corresponds to the sheet assembly station 3. That is, the top-layer cardboard glue spraying component 5 sprays glue towards the sheet assembly station 3 to smoothly apply glue to the corresponding area of ​​the positioned top-layer cardboard, waiting for the sheet to be smoothly adhered to the corresponding area for assembly. For example, the top-layer cardboard glue spraying component 5 includes a cardboard glue spraying gun facing the sheet assembly station 3. The top-layer cardboard glue spraying component 5 can spray glue vertically from top to bottom or diagonally from top to bottom (so that the space directly above the sheet assembly station 3 is freed up for the sheet picking, transfer, and loading robot 7, making the structure more reasonable and the installation and debugging relatively convenient).

[0048] For example, the sheet material handling and transfer robot 7 includes a sheet material transfer and assembly nozzle 70, which removes the sheets from the sheet material bin 6 and transfers them to the top layer of the lifting feeding platform. The sheet material handling and transfer robot 7 can be configured in various ways, such as using an industrial robotic arm (industrial robot) with a sheet material transfer and assembly nozzle 70, or a translational lifting platform 73 (including horizontal and vertical movement).

[0049] As an additional optimization, the sheet assembly station 3 is located in the lid area 11 of the top cardboard rising and positioning position 10, so that the sheet assembly is connected to the lid area 11 of the integrated cardboard box. This allows the sheet to be easily detected and seen when the integrated cardboard box is opened, and also prevents the sheet from detaching when the integrated cardboard box is normally storing items. Of course, it can also be located in other areas (such as the bottom area of ​​the box).

[0050] The lifting feeding platform includes a lifting paper support frame, which is connected to a lifting drive motor (such as a servo motor). The lifting drive motor drives the lifting feeding platform (such as its lifting paper support frame) to rise and fall. The lifting feeding platform (such as its lifting paper support frame) can be equipped with a sensor (such as a photoelectric eye) to ensure that the top layer of cardboard rises and is in place. The sensor is connected to the lifting drive motor to control the lifting feeding platform (such as its lifting paper support frame) to rise gradually so that the top layer of cardboard rises smoothly and stops in place (such as stopping at the height position of the corresponding sheet assembly station 3).

[0051] For example, the cardboard transfer feeding nozzle 2 includes a lifting and translating cardboard transfer nozzle component, which can perform lifting and translating (e.g., lateral) movements to lift the cardboard for lateral movement, then lower and release the cardboard, and then return to its original position to repeat the action. In the figure, the motor 21 drives the transverse frame 22 to move back and forth on the transverse track 23, and the cylinder 24 drives the lifting frame 25 to lift and lower on the transverse frame 22. The cardboard transfer feeding nozzle 2 body is mounted on the lifting frame 25.

[0052] There are many structural options for the sheet material bin 6, which is a mature technology. For example, the material bin structure in paper box or paper cup forming machines such as wine boxes and folding boxes can be used for feeding materials from the top output port or the bottom output port. There are many options and the technology is relatively mature. For example, if the sheet material bin 6 is located on the left side of the feeding lifting platform, the sheet material bin 6 can be equipped with a lifting tray that rises gradually to feed materials. The lifting suction nozzle that moves left and right can be used as a sheet material picking, transfer and loading robot 7. The following embodiments can be adopted: the sheet material bin 6 includes a stacking bin, which can be a vertical stacking bin or an inclined stacking bin. The figure shows a vertical stacking bin. The stacking bin is usually formed by several side plates to create a space for stacking sheet materials. The lower end of the stacking bin is the discharge port of the sheet material bin 6 (for the sheet materials to be output from it). The edge of the discharge port is provided with sheet material baffles 60 (such as small baffles, springs, etc.) to block the edge of the sheet material so that the sheet material can be output by utilizing the deformation of the sheet material when it is pulled out (e.g., sucked up). The discharge port is located above the sheet material assembly station 3.

[0053] There are various methods for the sheet material handling, transfer, and loading robot 7. For example, the sheet material handling, transfer, and loading robot 7 includes a rotary positioning arm 71, on which a sheet material transfer and assembly suction nozzle 70 is provided for gripping and releasing the sheet material. In this embodiment, all suction nozzles are air nozzles, which are mature technologies for suction and release. The rotary positioning arm 71 and the sheet material transfer and assembly suction nozzle 70 are located above the sheet material assembly station 3. The rotary positioning arm 71 has a rotary stopping position for picking up sheet material and a rotary stopping position for loading sheet material. The rotary positioning arm 71 rotates to change positions, and the sheet material transfer and assembly suction nozzle 70 rotates and changes positions together with the rotary positioning arm 71. At the rotary stopping position for picking up sheet material and the rotary stopping position for loading sheet material... The sheet material transfer and assembly nozzle 70, as shown in the diagram, is in a rotating and stopping position when it faces upward as the rotating shifting arm 71 rotates. When it faces downward as the rotating shifting arm 71 rotates, it is in a rotating and stopping position for loading. At the rotating and stopping position for picking up the sheet material, the nozzle 70 moves forward and backward towards the outlet of the sheet material bin 6, enabling it to pick up the sheet material from the bin 6. At the rotating and stopping position for loading, the nozzle 70 moves upward and downward towards the sheet material assembly station 3 below, enabling it to assemble the sheet material, transferring it to this location and pressing it onto the (top) cardboard for assembly. For example, the rotating shifting arm 71 is connected to a rotating support shaft 711 and is driven by a corresponding power source to rotate and shift. Additionally, a power source is installed on the rotating shifting arm 71 to drive the sheet material transfer and assembly nozzle 70 to extend and retract.

[0054] In this embodiment, further optimization is achieved by using a single power source to drive the rotational positioning arm 71 and the corresponding actions of the sheet material transfer and assembly nozzle 70. The sheet material handling and transfer robot 7 includes a rotary positioning arm 71, on which the sheet material transfer and assembly nozzle 70 is mounted (details omitted - see above). Additionally, the sheet material handling and transfer robot 7 also includes a cam swing arm 72 and a lifting seat 73. The lifting seat 73 is mounted on a vertical track 731 and is connected to the lifting power component 74 (such as a cylinder or motor power source). The connection is made so that the lifting power component 74 drives the lifting seat 73 (along the vertical track 731) to lift. The lifting seat 73 is provided with a rotating support shaft 711. The rotating shifting arm 71 is connected to the rotating support shaft 711. The rotating shifting arm 71 rotates around the rotating support shaft 711 on the lifting seat 73 (such as a forward and reverse rotation shifting method). The cam swing arm 72 is connected to the swing support shaft 721. The cam swing arm 72 swings around the swing support shaft 721. It also has a structure that coordinates and drives the rotating shifting arm 71 and the cam swing arm 72 to move together.

[0055] The cam rocker arm 72 is provided with a cam groove hole 9, and the rotary support shaft 711 is fitted through the cam groove hole 9. When the rotary support shaft 711 moves up and down with the lifting seat 73, the rotary support shaft 711 moves up and down in the cam groove hole 9, thereby driving the cam rocker arm 72 to swing around the swing support shaft 721 through the trajectory of the cam groove hole 9. The cam rocker arm 72 is provided with a guide shaft 722. When the cam rocker arm 72 swings, the guide shaft 722 swings together with the cam rocker arm 72. The rotary shifting arm 71 is provided with a guide rail 712. The guide shaft 722 is connected to the guide rail 712. The guide shaft 722 can not only move relative to the guide rail 712, but also rotate relative to the guide rail 712. The cam groove hole 9 is used to enable the rotary shifting arm 71 to perform up and down rotation and then up and down movements, and the guide shaft 722 is used to enable the rotary shifting arm 71 to perform up and down rotation and then up and down movements, guiding the rotation of the cam rocker arm 71. The track 712 works in conjunction with the rotary shifting arm 71 to perform vertical rotation and reversal, as well as lifting and lowering movements. The cam slot 9, guide shaft 722, and guide track 712 work together to enable the rotary shifting arm 71 to perform vertical rotation and reversal, as well as lifting and lowering movements. During operation, the lifting seat 73 moves up and down, driving the rotary support shaft 711 to move up and down. Through the track of the cam slot 9, the cam swing arm 72 swings around the swing support shaft 721. The guide shaft 722 can move and rotate relative to the guide track 712. The guide shaft 722 swings and moves along with the cam swing arm 72, allowing it to move and rotate relative to the guide track 712. This enables the rotary shifting arm 71 to rotate (e.g., back and forth) around the rotary support shaft 711, allowing it to perform vertical rotation and reversal, as well as lifting and lowering movements (i.e., it can still move and lower after reversal) to retrieve material from the sheet material bin 6 and press the sheet material onto the (top) cardboard for assembly. In this structure, the lifting seat 73 can be driven by a single power source to perform the lifting action, which is low in cost and has high operating efficiency due to mechanical linkage.

[0056] In this structure, the vertical track 731, the lifting power component 74, and the swing support shaft 721 are mounted on the mounting plate 75, which facilitates overall installation, assembly, and relocation adjustment. For example, the guide track 712 can be a straight track, or it can be a straight track with a groove structure of a straight slide. The guide shaft 722 is configured in the guide track 712 (groove structure of a straight slide) to cooperate in relative linear movement and relative rotation. The structure is simple and the operation is smooth. The guide track 712 is set to rotate relative to the guide shaft 722. The guide track 712 and the guide shaft 722 are set to move relative to each other along their track (such as a straight line). That is, the guide shaft 722 can move and rotate relative to each other on the guide track 712. For ease of explanation, the following structure is used as an example. In the vertical state of the cam rocker arm 72 (this state is used to illustrate the corresponding structure, i.e., the natural hanging state), its cam slot 9 includes an upper vertical slot section 90, a middle arc-shaped slot section 91, and a lower vertical slot section 92. The upper vertical slot section 90, the middle arc-shaped slot section 91, and the lower vertical slot section 92 are connected from top to bottom. Usually, the cam slot 9 has a symmetrical structure, with the upper vertical slot section 90 and the lower vertical slot section 92 aligned vertically. The guide shaft 722 is located on the arc center side (such as the center side) of the middle arc-shaped slot section 91, which can smoothly cooperate to enable the rotary shifting arm 71 to perform vertical rotation and turning movements. In addition, the middle arc-shaped slot section 91 is provided with an arc-shaped slot section that does not exceed a semicircle, which makes the relative movement of the rotary support shaft 711 in the cam slot 9 smoother, and the cam rocker arm 72 swings more smoothly.Referring to the accompanying drawings, the operation of the sheet material handling and transfer robot 7 is further explained. When the lifting seat 73 is in the high position, the rotary support shaft 711 is located in the upper vertical groove section 90 of the cam groove wheel and above the guide shaft 722. At this time, the lifting seat 73 moves up and down, the rotary support shaft 711 moves up and down in the upper vertical groove section 90, and the guide rail 712 and the guide shaft 722 also move up and down relative to each other. The rotary transfer arm 71 does not rotate but only moves up and down. The sheet material transfer and assembly suction nozzle 70 and the rotary transfer arm 71 move up and down together to handle the material handling and transfer. Similarly, when the lifting seat 73 is in the low position, the rotary support shaft 711 is located in the lower vertical groove section 92 of the cam groove wheel and below the guide shaft 722. At this time, the lifting seat 73 moves up and down, the rotary support shaft 711 moves up and down in the lower vertical groove section 92, and the guide rail 712 and the guide shaft 722 also move up and down relative to each other. The rotary transposition arm 71 does not rotate but only moves up and down. The sheet material transfer assembly nozzle 70 moves up and down together with the rotary transposition arm 71 to transfer and press down the assembly. In addition, when the lifting seat 73 is in the middle position, the rotary support shaft 711 is in the middle arc-shaped groove section 91 of the cam groove wheel. At this time, the lifting seat 73 moves up and down, and the rotary support shaft 711 moves up and down in the middle arc-shaped groove section 91. The rotary support shaft 711 moves vertically with the lifting seat 73. The rotary support shaft 711 moves from the upper vertical groove section 90 or the lower vertical groove section 92 into the middle arc-shaped groove section 91 to move and cooperate, driving the cam swing arm 72 to swing around the swing support shaft 721. The guide shaft 722 swings and moves along with the cam swing arm 72. The guide shaft 722 can cooperate to pry and drive the guide rail 712 of the rotary transposition arm 71 to rotate relative to each other, realizing the up and down rotation and repositioning of the rotary transposition arm 71.
