Description

Technical Field

[0001] This utility model relates to a flipping feeding device. Background Technology

[0002] For example, the flipping conveyor device CN221459292U, the flipping and inverting device CN221115817U, the flipping and inverting device and flipping and inverting conveyor equipment for shell production CN219340816U, and the shell flipping and switching device CN215041550U, etc., have a turntable (such as a pick-and-place device) similar to a large windmill in their flipping structure to flip and invert the cardboard (such as the shell) (the shell is flipped from face down to back down). They can be configured in the shell production equipment to connect the outer laminating unit (which can be called the front unit) and the inner laminating unit (which can be called the back unit) to cooperate with the front and inner surfaces of the board being laminated. In the outer laminating unit (which can be called the front-end unit), after the face paper is fed, it is first glued by the gluing roller and then conveyed by the suction conveyor belt. A positioning machine is set on the conveying path of the suction conveyor belt to grab the cardboard (such as gray board) and place it on the glued face paper. Then it is conveyed to the edge-wrapping machine to complete the edge wrapping (such as horizontal edge wrapping and vertical edge wrapping). An oven (located before the positioning machine) can also be configured on the conveying path of the suction conveyor belt so that the face paper can stay in it and the glue on the face paper can take effect as soon as possible. A pressure structure and a correction structure (located after the positioning machine) can also be configured on the conveying path of the suction conveyor belt to press and position the laminated cardboard and to correct its position. There are multiple stations (e.g., 6-8 stations) for the paper to stay for corresponding operations (such as hot air drying in the oven, positioning by the positioning machine, and correction by the correction structure). There are even additional stop transition stations for stopping to facilitate the layout of the station or operation rhythm.

[0003] In the shell-making equipment, the outer mounting unit (which can be called the front-end unit) and the inner mounting unit (which can be called the back-end unit) are connected and operated in series by a flipping and inverting conveyor device to form a production line. When the inner mounting unit stops (such as due to material jamming, material shortage, etc., especially long-term shutdown due to malfunction), the outer mounting unit and the flipping and inverting conveyor device will also stop. If they do not stop and continue to operate, the shells to be pasted on the front will get stuck in the inner mounting unit, and the shells will be damaged, resulting in equipment failure and waste. If the machine is stopped, the adhesive on the face paper at multiple workstations will degrade after a certain period of downtime. This will result in the remaining adhesive-coated face paper (some even still attached to the cardboard) becoming defective, leading to waste of paper and other materials. Before restarting, these degraded sheets must either be removed, which is troublesome, time-consuming, and labor-intensive, or the machine can be run directly without processing, causing these degraded sheets to enter subsequent production stages, resulting in defective products and further material waste. Degraded adhesive can easily cause problems in subsequent production, leading to downtime, reduced efficiency, and higher production costs. Utility Model Content

[0004] In view of the technical problems existing in the background art, the present invention aims to provide a flipping and inverting conveyor device with material collection and temporary storage function, which can solve the problem of production waste and high production cost of the front unit caused by the shutdown of the downstream unit.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a flip-over inverted conveying device with a material receiving and temporary storage function, comprising a rotating main shaft, a feeding turntable, and a drive motor. The rotating main shaft is horizontally arranged on the frame and is connected to the drive motor. The feeding turntable is mounted on the rotating main shaft. The front side of the rotating main shaft is the material input station, and the rear side is the material output station. The feeding turntable is provided with a material receiving trough. The material receiving trough rotates with the feeding turntable and stops at the material input station to receive material. The material receiving trough rotates with the feeding turntable and stops at the material output station to output material. The feature is that the material receiving troughs are evenly distributed in the circumferential direction of the feeding turntable, and there is a residual material receiving and temporary storage area of ​​the feeding turntable in the rotating feeding direction from the material input station to the material output station; the residual material receiving and temporary storage area has a position area for multiple material receiving troughs to stop.

[0006] The following optimizations or supplementary explanations can be made to the above technical solutions.

[0007] For example, 16-20 material troughs can be evenly distributed along the circumference of the feeding turntable.

[0008] Specifically, the number of material troughs on the feeding turntable can be set to an even number, such as 16, 18, or 20.

[0009] For example, the drive motor is a servo motor, which drives the rotating spindle to rotate intermittently on the frame, and the feeding turntable is driven to rotate intermittently by the rotating spindle.

[0010] Among them, a horizontal intermittent feeding input mechanism of conveyor belt can be configured at the feeding input station, and a horizontal intermittent feeding output mechanism of conveyor belt can be configured at the feeding output station.

[0011] It can also be optimized so that when one material trough is at the feeding input station, the other material trough is at the feeding output station.

[0012] The rotating spindle has an intermittent normal feeding mode, in which it rotates intermittently by 180 degrees, 90 degrees, or 60 degrees; it also has an intermittent waste material collection and distribution mode, in which it rotates intermittently according to the number of material troughs on the feeding turntable. This allows for mode switching to achieve normal feeding and waste material collection and distribution.

[0013] In addition, a flipping and inverting conveyor with a material collection and temporary storage function is installed in the shell production line. The front end of this device is connected to the outer shell mounting machine, and the back end of this device is connected to the inner shell mounting machine.

[0014] The production path of the outer laminating unit contains multiple paper-carrying stations with pre-adhesive paper, and the number of material troughs in the residual material collection and storage area is no less than the number of paper-carrying stations. The beneficial effects of this utility model are that the flip-over inverted conveyor device with a material collection and temporary storage function can ensure that the preceding unit can continue to operate even when the subsequent unit stops, and can normally process all the remaining material (with adhesive paper applied) to complete the preceding process and output it. The remaining material is received and temporarily stored on the feeding turntable (located in the remaining material collection and temporary storage area) one by one, avoiding material waste and reducing production costs. The remaining material output from the feeding turntable after the preceding process can be manually removed; even when the subsequent unit restarts, the remaining material temporarily stored on the feeding turntable can still be supplied normally.

[0022] 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.

[0023] Referring to the accompanying drawings, the inverted conveyor 9 in this embodiment can be used in a leather packaging production line to connect the outer mounting unit 7 and the inner mounting unit 8. It includes a rotating spindle 1, a feeding turntable 2, and a drive motor 3. The rotating spindle 1 is horizontally mounted on the frame 4 and is connected to the drive motor 3. The drive motor 3 drives the rotating spindle 1 to rotate on the frame 4 to feed materials. The feeding turntable 2 is mounted on the rotating spindle 1 and has a material receiving trough 20. The feeding turntable 2 and the material receiving trough 20 rotate together with the rotating spindle 1. The feeding turntable 2 can be configured with... It is disc-shaped or strip-shaped; the front of the rotating spindle 1 is the feeding input station 5, where materials (such as outer coverings, etc.) are fed in for flipping; the rear of the rotating spindle 1 is the feeding output station 6, where the flipped materials are fed out; the material receiving trough 20 is used to receive (accept) the input materials, flip them, and then output them. One material receiving trough 20 can hold one material. The material receiving trough 20 rotates with the feeding turntable 2 and stops at the feeding input station 5 to receive materials. The material receiving trough 20 rotates with the feeding turntable 2 and stops at the feeding output station 6 to output materials. This is a relatively mature technology. Based on this, the inverted conveyor device of this utility model has a material collection and temporary storage function, which can solve the problem of production waste and high production costs of the front-end unit (such as the outer-end unit 7) caused by the shutdown of the downstream unit (such as the inner mounting unit 8). The inverted conveyor device has material receiving troughs 20 evenly distributed in the circumferential direction of the feeding turntable 2. In addition, there is a material collection and temporary storage area of ​​the feeding turntable 2 in the rotational feeding direction from the feeding input station 5 to the feeding output station 6. The material collection and temporary storage area refers to the glued paper (some of which has been mounted on the paperboard) remaining in each station in the front-end unit of the shell production line (due to the shutdown of the downstream unit). The material collection and temporary storage area has a position area for multiple material receiving troughs 20 to stay. This is to ensure that even if the downstream unit stops, the upstream unit can continue to operate for a period of time, completing the work of the upstream unit on the glued paper at each station, and completing the complete upstream process (such as outer mounting) on ​​these leftover materials. This avoids material waste caused by the shutdown of these leftover materials (glue). These leftover materials will be output one by one during the continued processing of the upstream unit and received one by one by the feeding turntable 2 of the flipping and inverting conveyor. The feeding turntable 2 is evenly distributed with material troughs 20 in the circumferential direction. The temporary storage area for leftover materials has a position area for multiple material troughs 20 to stay. The feeding turntable 2 is evenly distributed with material troughs 20 to receive and temporarily store these leftover materials one by one. For example, if there are eight stations with glued paper remaining in the upstream unit, corresponding to eight residual materials, then the residual material collection temporary storage area must have at least eight material receiving troughs 20. The more material receiving troughs 20 the residual material collection temporary storage area has, the stronger the capacity to receive (accept) the amount of residual material.

[0024] When the inverted conveyor with material collection and storage function is in operation, during normal operation, the front and rear units run normally. The feeding turntable 2 receives the material from the feeding input station 5 that has completed the previous process (such as outer mounting) and flips it to feed the material out at the feeding output station 6. When the rear unit stops, the inverted conveyor with material collection and storage function can ensure that the front unit continues to run, processing the glued paper (i.e., the leftover material) inside to complete the previous process and output it. All the leftover material output is collected (completely collected) and temporarily stored by the inverted conveyor with material collection and storage function. When the rear unit restarts, the inverted conveyor with material collection and storage function can supply the leftover material.

[0025] This inverted conveyor with a material receiving and temporary storage function ensures that the preceding unit can continue operating even when the subsequent unit stops, processing all remaining material (already coated with adhesive paper) normally to complete the preceding process and output it. The remaining material is received and temporarily stored on the feeding turntable 2 (located in the remaining material collection and temporary storage area) by the corresponding material troughs 20, avoiding material waste and reducing production costs. The remaining material output from the feeding turntable 2 after the preceding process can be manually removed; even when the subsequent unit restarts, the remaining material temporarily stored on the feeding turntable 2 can still be supplied normally.

[0026] The following optimizations or further explanations can be made based on the above embodiments.

[0027] For example, 16-20 material troughs 20 are evenly distributed along the circumference of the feeding turntable 2, which can meet the needs of most shell production lines to ensure that all excess material is collected. For instance, setting an even number of material troughs 20 on the feeding turntable 2, such as 16, 18, or 20, results in a reasonable structure and facilitates layout and operation. Of course, more or fewer material troughs 20 can be set according to actual needs.

[0028] For example, the drive motor 3 is a servo motor. Servo motor control technology is mature, and the rotation angle of the rotating spindle 1 is easy to preset and control in order to cooperate with the rotating material receiving and temporary storage and rotating material conveying. The intermittent indexing rotation angle can be adjusted and set according to the needs. Among them, the drive motor 3 drives the rotating spindle 1 to rotate intermittently on the frame 4, and the feeding turntable 2 is driven by the rotating spindle 1 to rotate intermittently.

[0029] For example, a horizontal intermittent feeding input mechanism 50 with a conveyor belt is configured at the feeding input station 5, and a horizontal intermittent feeding output mechanism 60 with a conveyor belt is configured at the feeding output station 6. The input and output can use the same circular conveyor belt 56, or they can use different conveyor belts. Typically, multiple feeding turntables 2 are arranged horizontally side by side on the rotating main shaft 1, and the conveyor belts are arranged horizontally to each other (for longitudinal conveying). The feeding turntables 2 and the conveyor belts can be interspersed in the horizontal direction.

[0030] In addition, when one of the material troughs 20 is at the feeding input station 5, the other material trough 20 is at the feeding output station 6. This makes it easier for the two stations to operate synchronously for input and output, making feeding more efficient. Furthermore, the same drive source (such as motor 65) can be used for both input and output.

[0031] Among them, the rotating spindle 1 has an intermittent rotation normal feeding mode (which can be called mode one). In the intermittent rotation normal feeding mode, the rotating spindle 1 rotates intermittently at 1180 degrees, 90 degrees or 60 degrees to cooperate with the normal operation of the front and rear units. The rotating spindle 1 also has an intermittent rotation waste material collection and distribution mode (which can be called mode two). In the intermittent rotation waste material collection and distribution mode, the rotating spindle 1 rotates intermittently according to the quantity index of the material trough 20 on the feeding turntable 2. This mode is used to cooperate with the continued operation of the front unit when the rear unit stops and when the subsequent rear unit restarts, so as to collect and distribute waste material.

[0032] For example, in the diagram, the feeding turntable 2 has 20 material troughs. When the first material trough 20 is at the feeding input station 5, the eleventh material trough 20 is at the feeding output station 6. In the intermittent rotation normal feeding mode, the rotating spindle rotates 1180 degrees or 90 degrees intermittently. In the intermittent rotation residual material collection and distribution mode, the rotating spindle rotates 118 degrees intermittently (i.e., one revolution is divided into 20 intervals of intermittent rotation). The feeding input station 5 has a residual material collection temporary storage area of ​​the feeding turntable 2 in the rotation feeding direction from the feeding input station 5 to the feeding output station 6. For example, as shown in the figure, the feeding turntable 2 has 18 material troughs 20 in number. When the first material trough 20 is at the feeding input station 5, the tenth material trough 20 is at the feeding output station 6. In the intermittent rotation normal feeding mode, the rotating spindle rotates 1180 degrees or 60 degrees intermittently. In the intermittent rotation residual material collection and distribution mode, the rotating spindle rotates 120 degrees intermittently (i.e., one revolution is divided into 18 intervals of intermittent rotation). The feeding input station 5 has a residual material collection temporary storage area of ​​the feeding turntable 2 in the rotation feeding direction from the feeding input station 5 to the feeding output station 6. For example, as shown in the figure, the feeding turntable 2 has 16 material troughs 20 in number. When the first material trough 20 is at the feeding input station 5, the ninth material trough 20 is at the feeding output station 6. In the intermittent rotation normal feeding mode, the rotating spindle rotates 1180 degrees or 90 degrees intermittently. In the intermittent rotation residual material collection and distribution mode, the rotating spindle rotates 111.25 degrees intermittently (that is, one revolution is divided into 16 intervals of intermittent rotation).

[0033] The flip-over inverted conveyor 9 with material collection and temporary storage function is installed in the shell production line. The front end of the device 9 is connected to the outer shell laminating unit 7, and the rear end of the device 9 is connected to the inner shell laminating unit 8. The production path of the outer shell laminating unit 7 contains multiple paper-carrying stations with coated paper. The number of material-holding troughs 20 in the residual material collection and temporary storage area is no less than the number of paper-carrying stations. When the rear unit (outer shell laminating unit 7) stops, it can collect all the residual material (coated paper) in the front unit (inner shell laminating unit) to the maximum extent. For example, if there are eight residual materials corresponding to eight stations with coated paper remaining in the front unit, then the residual material collection and temporary storage area has at least eight material-holding troughs 20. The more material-holding troughs 20 corresponding to the residual material collection and temporary storage area, the stronger the capacity to receive (accept) the residual material.
