Description

Technical Field

[0001] This utility model belongs to the field of roll material feeding, and in particular relates to an automatic feeding device. Background Technology

[0002] In the production and processing of roll-to-roll media (such as roll-to-roll printing media in digital printing equipment), after the roll-to-roll at the unwinding station is used up, a new roll-to-roll needs to be replaced at the unwinding station to ensure continuous production. Current roll-to-roll replacement methods are usually manual or equipment-assisted (such as forklifts). If the roll diameter is small or the weight is light, it can be done manually. The empty roll is removed from the station, and the new roll-to-roll is installed on the roll-to-roll before being placed at the unwinding station. If the roll diameter or weight is too large, it cannot be done manually, and equipment-assisted replacement is required. This involves personnel operating specialized equipment to lift the roll-to-roll along with the roll to the unwinding station for installation. This method of relying entirely on manual or equipment loading is cumbersome and leads to low production efficiency. When manual loading is required, the workload is heavy, and reliance on external equipment limits production. Utility Model Content

[0003] This utility model provides an automatic feeding device, which aims to solve the problems in the prior art where manual feeding is required, resulting in a heavy workload for personnel, and reliance on external equipment limits production.

[0004] This utility model is implemented as follows: an automatic feeding device for automatically feeding roll materials, comprising: The support frame consists of two upright panels spaced apart from each other. Two clamping components are provided, one on each side of the two upright plates and correspondingly arranged, and each clamping component is provided with a clamping position; The material shaft is detachably fixed at both ends to the clamping positions of the two upright plates. The material shaft has an installed state and a detached state. The material shaft is used to install the roll material. A rotating arm is rotatably mounted on the bracket. The rotating arm has an initial position and a preset position on its rotation trajectory. When the rotating arm is in the initial position, it is located below the material shaft in the disassembled state. When the rotating arm rotates from the initial position to the preset position, it can lift the material shaft. When the rotating arm rotates to the preset position, the material shaft is lifted above the clamping position. When the rotating arm rotates from the preset position to the initial position, both ends of the material shaft move into the clamping positions of the two clamping members respectively. A driving component is mounted on the bracket and drives the rotating arm to rotate between an initial position and a preset position.

[0005] Furthermore, when the rotating arm is in the initial position, the roll material mounted on the material shaft is placed on the ground, and the distance from the material shaft to the ground is greater than the distance from the rotating arm to the ground when it is in the initial position. The roll material rolls on the ground toward the rotating arm until the material shaft is on the motion trajectory above the rotating arm.

[0006] Furthermore, the rotation center of the rotating arm is located between the horizontal plane where the clamping member is located and the horizontal plane where the initial position is located, and is located close to the side of the clamping member. The preset position is located above the horizontal plane where the clamping member is located.

[0007] Furthermore, the rotation center of the rotating arm is located on one side of the orthographic projection direction of the clamping member. The rotating arm adopts a straight arm structure. The upper surface of the movable end of the rotating arm is provided with a groove for supporting the material shaft. When the rotating arm rotates from the initial position to the preset position, the material shaft can abut against the groove. When the rotating arm lifts the roll material and rotates to the preset position, the material shaft can roll to the rear end of the groove and be located above the clamping position.

[0008] Furthermore, bearings are provided at both ends of the material shaft, the bearings abut against the groove, and the bearings can roll on the groove.

[0009] Furthermore, the support is provided with a rotating shaft, and the driving component drives the rotating shaft to rotate. The rotation center of the rotating arm is fixed on the rotating shaft. The automatic feeding device also includes a detection component and a controller. The detection component includes a receiving part on the support and a detection part on the rotating shaft. The receiving part is connected to the controller. When the rotating arm rotates to a preset position, the detection part and the receiving part form a signal connection. The receiving part sends a detection status signal to the controller, and the controller controls the driving component to stop driving the rotating arm to rotate.

[0010] Furthermore, the rotating arm consists of two parts, respectively located at both ends of the rotating shaft and close to the upright plate. The clamping component is a VT-type safety chuck, the outer disk of which can move towards the upright plate to open the clamping position. A sensor for detecting the outer disk is provided on the upright plate facing the VT-type safety chuck. A control switch for controlling the start or stop of the drive component is provided on the bracket. Both the sensor and the control switch are electrically connected to the controller. When the outer disk moves towards the upright plate, the sensor detects the outer disk and sends a signal to the controller. The controller then sends a signal to the control switch to start the drive component.

[0011] Furthermore, a connecting rod is connected between the two rotating arms, and the connecting rod is arranged parallel to the rotating shaft.

[0012] Furthermore, the drive unit consists of two parts, each configured with one of the two rotating arms.

[0013] The beneficial effects achieved by this utility model are as follows: by setting a rotatable rotating arm and setting an initial position and a preset position on the rotation trajectory of the rotating arm, the rotating arm can be positioned below the material shaft in the disassembled state in the initial position. In the preset position, the material shaft is raised to above the clamping position. The rotating arm is driven to rotate by the driving component so that the rotating shaft raises the material shaft to the preset position and then lowers it so that both ends of the material shaft can be inserted into the clamping position. This eliminates the need for personnel to move or use special equipment to lift and install the roll material. It reduces the burden on personnel and is not limited by special equipment, making production more flexible. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] See Figures 1-2This utility model provides an automatic feeding device for automatically feeding a roll of material 100. It includes a support 1, clamping members 2, a rotating arm 3, a driving member 4, and a material shaft 101. The support 1 includes two relatively spaced upright plates 11, which provide a platform for the roll of material 100. Two clamping members 2 are respectively located on opposite sides of the two upright plates 11 and are correspondingly positioned, meaning the two clamping members 2 are at the same position in both the vertical and horizontal directions. The two clamping members 2 are used to clamp and fix both ends of the material shaft 101. Each clamping member 2 has a clamping position 21 (see [reference]). Figure 4 and Figure 5 The material shaft 101 is detachably fixed at both ends to the clamping positions 21 of the two upright plates 11. The material shaft 101 has an installed state and a disassembled state. The material shaft 101 is used to install the roll material 100. That is, during the production process, after the material shaft 101 installs the roll material 100, it is installed on the clamping position 21. At this time, the material shaft 101 is in the installed state. After the current roll material 100 is produced, the material shaft 101 needs to be removed to continue installing the next roll material 100. At this time, the material shaft 101 is in the disassembled state. This cycle continues. The rotating arm 3 is rotatably mounted on the bracket 1. The rotating arm 3 has an initial position and a preset position on its rotation trajectory. When the rotating arm 3 is in the initial position, the rotating arm 3... Located below the material shaft 101 in the disassembled state, when the rotating arm 3 rotates from the initial position to the preset position, the rotating arm 3 can lift the material shaft 101, that is, lift the roll material 100 together. When the rotating arm 3 rotates to the preset position, the material shaft 101 of the roll material 100 is lifted above the clamping position 21. When the rotating arm 3 rotates from the preset position to the initial position, both ends of the material shaft 101 move into the clamping positions 21 of the two clamping members 2 respectively. That is, when the rotating arm 3 descends, it can make the material shaft 101 descend to the clamping position 21 at the current position and be locked in the clamping position 21. The driving member 4 is provided on the bracket 1 and drives the rotating arm 3 to rotate between the initial position and the preset position.

[0018] By setting a rotatable rotating arm 3 and setting an initial position and a preset position on the rotation trajectory of the rotating arm 3, the rotating arm 3 can be positioned below the material shaft 101 in the disassembled state in the initial position. In the preset position, the material shaft 101 is raised to be above the clamping position 21. The rotating arm 3 is driven to rotate by the driving component 4 so that the rotating shaft 6 raises the material shaft 101 to the preset position and then lowers it so that both ends of the material shaft 101 can be inserted into the clamping position 21. This eliminates the need for personnel to move or use special equipment to lift and install the roll material 100. It also reduces the burden on personnel and is not limited by special equipment, making production more flexible.

[0019] The automatic feeding device provided by this utility model can reduce the difficulty of feeding the roll material 100 to improve production efficiency, reduce the workload of personnel, and is not limited to feeding on special equipment, making production more flexible.

[0020] Furthermore, when the rotating arm 3 is in its initial position, the roll 100 mounted on the material shaft 101 is placed on the ground. The distance from the material shaft 101 to the ground is greater than the distance from the rotating arm 3 to the ground in its initial position. The roll 100 rolls onto the rotating arm 3 on the ground until the material shaft 101 is on the motion trajectory above the rotating arm 3. Thus, when the roll 100 needs to be installed, it can be rolled directly onto the rotating arm 3 from the ground, allowing the material shaft 101 with the roll 100 mounted to move onto the motion trajectory above the rotating arm 3. This eliminates the need to lift the roll 100 from the ground, reducing the workload for personnel and further simplifying the loading of the roll 100.

[0021] Furthermore, the rotation center of the rotating arm 3 is located between the horizontal plane where the clamping member 2 is located and the horizontal plane where the initial position is located, and is close to the clamping member 2. Specifically, in terms of vertical height, the rotation center is higher than the initial position but lower than the position where the clamping member 2 is located, and is close to the clamping member 2. The preset position is located above the horizontal plane where the clamping member 2 is located. This ensures that when the rotating arm 3 lifts the material shaft 101 above the clamping member 2, the material shaft 101 is positioned above the clamping position 21, and when the rotating arm 3 lowers, the material shaft 101 falls into the clamping position 21. It should be noted that, in order to avoid the preset position being too high, causing the material shaft 101 to deviate from the entrance position of the clamping position 21 when the rotating arm 3 rotates from the preset position to the initial position, the preset position does not need to be set too high. It only needs to ensure that the rotating arm 3 can reach above the clamping position 21 when lifting the roll material 100.

[0022] See Figure 1 Specifically, the rotating arm 3 can be a straight arm structure. In this way, when setting the rotation center of the rotating arm 3, the rotation center of the rotating arm 3 can be set off to one side of the positive projection direction of the clamping member 2. This design scheme can make the entire automatic feeding device occupy less space when the internal space between the two upright plates 11 is large enough to accommodate the rotating arm 3. In addition, this structure makes the angle between the rotating arm 3 and the initial position less than 90 degrees when it rotates to the preset position, so that the roll 100 will not be in an inverted position. This can reduce the limiting structure of the roll 100 being lifted by the rotating arm 3. For example, the following groove 311 structure can be set to limit the roll 100 when it is lifted and when it reaches the preset position.

[0023] In addition, the rotating arm 3 can also be an arc-shaped structure (not shown in the figure), such as but not limited to a sickle structure. When this structure is adopted, the rotation center can be set on one side of the orthographic projection direction of the clamping member 2, or it can be set directly in the orthographic projection direction. When the arc-shaped rotating arm 3 lifts the roll 100 to the preset position, it can avoid the clamping member 2 so as to reach the preset position smoothly. When the internal space between the two upright plates 11 is insufficient to accommodate the rotating arm 3, this design can effectively utilize the space other than the automatic feeding device, so as to be compatible with the installation requirements of different spaces.

[0024] See Figure 1 In this embodiment, the rotation center of the rotating arm 3 is set on one side of the orthogonal projection direction of the clamping member 2, and the rotating arm 3 adopts a straight arm structure. The upper surface of the movable end of the rotating arm 3 is provided with a groove 311 for supporting the material shaft 101. When the rotating arm 3 rotates from the initial position to the preset position, the material shaft 101 can abut against the groove 311. When the rotating arm 3 lifts the roll 100 and rotates to the preset position, the material shaft 101 can roll to the rear end of the groove 311 and be located above the clamping position 21. The groove 311 is designed so that when the rotating arm 3 rotates to the bottom of the material shaft 101 and continues to rise, the material shaft 101 can be effectively lifted by the groove 311, preventing the material shaft 101 from slipping away from the rotation direction along the rotating arm 3. When the rotating arm 3 rotates to the preset position, the material shaft 101 can be moved to the rear end of the groove 311. The rear end of the groove 311 can position the material shaft 101 to ensure that the material shaft 101 is above the clamping position 21, and at the same time, it can prevent the material shaft 101 from slipping away from the rotating arm 3 towards the rotation center.

[0025] See Figure 2 , Figure 5 Furthermore, bearings 5 ​​are provided at both ends of the material shaft 101, and the bearings 5 ​​abut against the groove 311, allowing them to roll on the groove 311. In this way, when the material shaft 101 moves within the groove 311, rolling friction can be generated between the material shaft 101 and the groove 311 through the bearings 5, thereby reducing the difficulty of the material shaft 101 moving within the groove 311 due to the excessive weight of the roll material 100.

[0026] See Figure 1 , Figure 3Furthermore, the support 1 is equipped with a rotating shaft 6, and the drive unit 4 drives the rotating shaft 6 to rotate. The rotation center of the rotating arm 3 is fixed on the rotating shaft 6. The automatic feeding device also includes a detection component 7 and a controller. The detection component 7 includes a receiving part 71 on the support 1 and a detection part 72 on the rotating shaft 6. The receiving part 71 is connected to the controller. When the rotating arm 3 rotates to a preset position, the detection part 72 and the receiving part 71 form a signal connection. The receiving part 71 sends a detection completion signal to the controller, and the controller controls the drive unit 4 to stop driving the rotating arm 3 to rotate. In this way, by setting the detection component 7, the drive unit 4 can be effectively provided with a judgment signal that the rotating arm 3 has rotated to the preset position, thereby improving the automation level of feeding.

[0027] It should be noted that the controller is the control center of the main equipment (such as the control center in digital printing equipment) used in conjunction with the automatic feeding equipment.

[0028] See Figure 4 , Figure 5 Furthermore, the rotating arm 3 consists of two parts, which are respectively located at both ends of the rotating shaft 6 and close to the vertical plate 11. The two material shafts 101 can respectively support both ends of the roll, enabling the roll to be lifted and installed smoothly. The clamping part 2 is a VT-type safety chuck. The outer plate 22 of the VT-type safety chuck can move towards the vertical plate 11 to put the clamping position 21 in the open state. Figure 4 The outer plate 22 is in the closed clamping position 21 is not open. Figure 5 With the outer disc 22 in the open position (clamping position 21 is in the open state), a sensor 8 for detecting the outer disc 22 is installed on the upright plate 11 facing the VT-type safety chuck. A control switch 9 for controlling the start or stop of the drive component 4 is installed on the bracket 1. Both the sensor 8 and the control switch 9 are electrically connected to the controller. When the outer disc 22 moves towards the upright plate 11, the sensor 8 sends a signal to the controller detecting the outer disc 22, and the controller sends a start signal to the control switch 9 to control the drive component 4. In this way, by setting the sensor 8 to detect whether the clamping position 21 of the clamping component 2 is in the open state, if so, the drive component 4 is allowed to drive the rotating arm 3 to rotate; if the clamping position 21 is not open, the drive component 4 is not allowed to drive the rotating arm 3 to move. This avoids erroneous operations such as driving the rotating arm 3 to lift the roll material 100 when the clamping position 21 is not open, thus improving the safety performance of the automatic feeding device.

[0029] Furthermore, a connecting rod 10 connects the two rotating arms 3, and the connecting rod 10 is arranged parallel to the rotating shaft 6. By setting the connecting rod 10, the two rotating arms 3 can be formed into a complete integral structure, improving the structural stability between the two rotating arms 3, thereby increasing the weight that can be borne and making the lifting of the roll 100 more stable.

[0030] Furthermore, there are two drive components 4, each configured with one of the two rotating arms 3. By having the two drive components 4 drive the two rotating arms 3 respectively, the drive structure can be simplified, while ensuring that both ends of the roll shaft have the same lifting force, resulting in smoother lifting.

[0031] Specifically, the rotating arm 3 includes a first arm 31 and a second arm 32 that are bent and connected. The rotating shaft 6 passes through the connection between the first arm 31 and the second arm 32. The first arm 31 has a straight arm structure, and a groove 311 is provided on the first arm 31. The driving member 4 drives the second arm 32 to rotate around the rotation center of the rotating arm 3. The two ends of the connecting rod 10 are respectively connected to the second arms 32 of the two rotating arms 3. By adopting a bent structure for the driving end (second arm) and the lifting end (first arm) of the rotating arm 3, the space occupied by the rotating arm 3 in the vertical plate 11 can be reduced, making the structure more compact.

[0032] In this embodiment, the drive component 4 may be, but is not limited to, a cylinder, a hydraulic cylinder, etc.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
