Description

Technical Field

[0001] The utility model belongs to the technical field of material transfer, and in particular relates to a batch blanking device. Background Art

[0002] For the batch transfer of materials, the conventional method is to place multiple materials on the same tray, and after the tray is moved to the specified position, all materials are unloaded from the tray to the corresponding container or workstation. In order to improve the efficiency of batch transfer of materials, some double-layer tray structures with holes are provided in the prior art, and the side of the lower material plate is connected to a pushing mechanism such as a cylinder or an oil cylinder, such as the lead buckle tray provided in patent CN112147298B. When this double-layer tray structure with holes is used, the lower material plate is driven to move back and forth by the pushing mechanism, so that its hole position is misaligned or aligned with the upper material plate. In the misaligned state, the lower material plate closes the hole position of the upper material plate, and the upper material plate can play the role of supporting the material normally. In the aligned state, the hole positions of the lower material plate and the upper material plate coincide, and the material can fall directly downward to achieve batch dropping. However, when the entire tray needs to be transferred from one workstation to another for batch blanking, due to the setting of the pushing mechanism, it is inevitable to connect the circuit or air circuit, resulting in the limitation of the overall movable range and mobility of the tray. In addition, the overall weight and size of the tray will be relatively large, which is not conducive to manual handling in semi-automatic production lines. As a result, this tray structure has limitations in actual application and has low flexibility. Utility Model Content

DETAILED DESCRIPTION

[0021] like Figure 1-Figure 5 As shown, the utility model provides a batch blanking device, including an upper material plate 1, a lower material plate 2 and an elastic member 3, wherein the upper material plate 1 is provided with a plurality of material placement holes 11, and the lower material plate 2 is slidably provided below the upper material plate 1, that is, relative sliding can occur between the lower material plate 2 and the upper material plate 1, and when relative sliding occurs between the lower material plate 2 and the upper material plate 1, the direction of the sliding can be regarded as the direction in which the lower material plate 2 slides relative to the upper material plate 1. The lower material plate 2 is provided with a plurality of blanking holes 21 corresponding to the number and position of the plurality of material placement holes 11, so that the lower material plate 2 can align the plurality of blanking holes 21 with the plurality of material placement holes 11 one by one after relative sliding occurs, and a push plate 221 for a thrust mechanism to abut is provided on one side of the lower material plate 2, that is, the push plate 221 is used for the pushing mechanism to apply thrust. The output end of the thrust mechanism is the end that directly applies thrust. For example, when the thrust mechanism is an oil cylinder or a gas cylinder, the output end is the end of its piston rod.

[0022] One end of the elastic member 3 is connected to the upper material plate 1, and the other end is connected to the lower material plate 2. The elastic expansion direction of the elastic member 3 is in the same direction as the direction in which the lower material plate 2 slides relative to the upper material plate 1. The straight line in which the elastic expansion direction of the elastic member 3 is located is perpendicular to the push plate 221. The straight line in which the elastic expansion direction of the elastic member 3 is located specifically refers to a straight line that passes through the elastic member 3 and extends along the elastic expansion direction of the elastic member 3. Therefore, when the lower material plate 2 and the upper material plate 1 slide relative to each other by applying a thrust to the push plate 221, the elastic member 3 is compressed or stretched. In addition, when the elastic member 3 is in a natural state, that is, when the batch blanking device is in a static state and the push plate 221 is not subjected to a thrust, a plurality of the blanking holes 21 and a plurality of the material placement holes 11 are misaligned.

[0023] The batch blanking device provided by the utility model, in a natural state, as shown in Figure 4, is misaligned between a number of the blanking holes 21 and a number of the material placement holes 11, and the bottoms of a number of the material placement holes 11 are in a blocked state, and materials can be placed and positioned through the material placement holes 11. By applying a thrust to the push plate 221 as a whole, the lower material plate 2 and the upper material plate 1 slide relative to each other, and a number of blanking holes 21 are aligned with a number of material placement holes 11 so that the materials fall at one time, and the elastic member 3 is compressed or stretched during this process. When the push plate 221 loses its thrust, the elastic force of the elastic member 3 drives the lower material plate 2 and the upper material plate 1 to reset, and the elastic force of the elastic member 3 can be used to maintain the relative position of the lower material plate 2 and the upper material plate 1 in the sliding direction, thereby playing a self-locking role.

[0024] The utility model can realize the relative sliding and resetting between the upper material plate 1 and the lower material plate 2 when the thrust mechanism is only in contact with the push plate 221, without connecting the thrust mechanism to the upper material plate 1 or the lower material plate 2. Therefore, when moving the batch blanking device, it is not necessary to move the thrust mechanism together, the movable range is larger, the convenience of movement is higher, and the overall weight and volume of the device are smaller, which is more convenient for use in occasions where manual handling is required in a semi-automatic production line. And compared with the method of setting the thrust mechanism to be detachable, the utility model can not only save the operation of frequently disassembling and assembling the thrust mechanism, but also ensure that the relative position of the lower material plate 2 and the upper material plate 1 in the sliding direction does not change as much as possible during the overall movement of the device, reduce or avoid the relative movement between the lower material plate 2 and the upper material plate 1 due to inertia or shaking during the movement, and improve the reliability and stability of the batch transfer of materials. Therefore, it can be applied to more scenes of batch transfer and blanking requirements of materials, and the applicable scene range is wider and the use flexibility is higher.

[0025] The edge of the upper material plate 1 is provided with a circle of frame 12, and the lower material plate 2 and the elastic member 3 are both located inside the frame 12. The provision of the frame 12 can increase the structural strength of the upper material plate 1 and facilitate the installation of the lower material plate 2 and the elastic member 3. The dimension of the upper material plate 1 in the relative sliding direction with the lower material plate 2 is larger than the dimension of the lower material plate 2 in the same direction, so that a space is reserved inside the frame 12 for the lower material plate 2 and the upper material plate 1 to slide relative to each other.

[0026] The edge of the lower material plate 2 is provided with a circle of frame 22, and frame 22 is also located inside frame 12. The provision of frame 22 can increase the structural strength of the lower material plate 2 and facilitate the installation of the lower material plate 2. Based on the provision of frame 12 and frame 22, one side of the frame 12 or frame 22 forms the push plate 221, that is, when the push plate 221 is provided on one side of the upper material plate 1, the push plate 221 is specifically one side of frame 12, and when the push plate 221 is provided on one side of the lower material plate 2, the push plate 221 is specifically one side of frame 22. In specific applications, it can be selected to be set to push the upper material plate 1 to move or the lower material plate 2 to move according to the actual production line requirements. In the utility model, it is preferably set to push the lower material plate 2 to move, and the position of the material does not need to be changed during the movement.

[0027] When the push plate 221 is selected as one side of the frame 22 in the embodiment, Figure 1 and Figure 2 As shown, an opening 121 for the output end of the thrust mechanism to pass through is provided on one side of the frame 12 and the frame 2 2 corresponding to the side where the push plate 221 is located, so that the output end of the thrust mechanism can contact the side of the frame 2 22 and apply thrust.

[0028] The two sides of the frame 22 facing each other are provided with one of the guide grooves 222 and the guide posts 122, and the two sides of the frame 12 facing each other are provided with the other of the guide grooves 222 and the guide posts 122. For example, when the two sides of the frame 22 facing each other are provided with the guide grooves 222, the two sides of the frame 12 facing each other are provided with the guide posts 122, and vice versa. The length direction of the guide grooves 222 is in the same direction as the elastic expansion direction of the elastic member 3, and the guide posts 122 are correspondingly arranged in the guide grooves 222, that is, the frame 22 and the frame 1 are slidably matched along the elastic expansion direction of the elastic member 3 through the guide posts 122 and the guide grooves 222, so as to realize the sliding and support between the lower material plate 2 and the upper material plate 1, and the structure is simple, the processing is convenient and it is conducive to controlling the cost. Among them, the side of the frame 22 and the frame 12 on which the guide grooves 222 or the guide posts 122 are provided is specifically the side where the push plate 221 is not located.

[0029] Based on the above-mentioned embodiment in which the guide groove 222 and the guide post 122 are provided, it is further preferred that the guide groove 222 is provided on two sides of the frame 22 that are opposite to each other, and the guide groove 222 is a through groove, and the guide post 122 is provided on two sides of the frame 12 that correspond to the position of the guide groove 222. The number of the elastic member 3 can be set to one or two. When the number of the elastic member 3 is one, one end of the elastic member 3 is connected to one side of the frame 22 provided with the guide groove 222, and the other end is connected to the guide post 122 that penetrates the guide groove 222 on the side of the frame 22. In order to improve the stability of the frame 22 and the frame 12 during the reset movement, the number of the elastic members 3 can be preferably two. When the number of the elastic members 3 is two, one end of the two elastic members 3 is connected to the two sides of the frame provided with the guide groove 222, and the other end is connected to the guide posts 122 on both sides of the frame 12. In this arrangement, the guide post 122 can be used as a fixing member at one end of the elastic member 3, and the guide post 122, the guide groove 222 and the elastic member 3 and other structures can be arranged by means of the internal space of the frame 1 12 and the frame 2 22, which can not only reduce the space occupied outside the entire device, thereby reducing the overall volume of the device, but also protect the elastic member 3 when the device moves as a whole. Among them, the specific connection method of the two ends of the elastic member 3 can be locked by screws, or one end of the elastic member 3 is hooked on the guide post 122, and a fixing block is provided on one side of the frame 2 2 provided with the guide groove 222, and the other end of the elastic member 3 is hooked on the fixing block. The elastic member 3 can be specifically a spring, an elastic rubber block or other elastically compressible material.

[0030] In some embodiments of the present invention, when the target material is relatively light, the support requirements for the lower material plate 2 are relatively lower, and the sliding support between the lower material plate 2 and the upper material plate 1 can be achieved by only using the guide groove 222 and the guide column 122 between the frame 2 22 and the frame 1 12 .

[0031] In other embodiments of the present invention, when the target material is heavy, such as a metal block, etc., a guide rail slider structure is further provided between the frame 12 and the frame 2 22, and the guide rail slider structure is slidably connected. The guide rail slider structure specifically includes a guide rail and a slider, the guide rail is provided inside the frame 12, the slider is provided on the frame 2 22 and slidably cooperates with the guide rail, or the guide rail and the slider are provided in opposite positions. This arrangement can improve the load-bearing capacity of the device, can withstand a larger load, and is more suitable for the case of heavy weight materials.

[0032] Among them, the second frame 22 can be integrally arranged on the lower material plate 2, or fixed to the lower material plate 2 by screws, and the first frame 12 is preferably fixed to the upper material plate 1 by screws to facilitate the installation of other components.

[0033] In the present invention, it is preferred that the thickness of the upper material plate 1 is greater than the thickness of the lower material plate 2, and / or a spacing smaller than the height of the material is provided between the upper material plate 1 and the lower material plate 2. These two configurations allow a certain height difference between the top of the material placement hole 11 and the top of the lower material plate 2, and the material placement hole 11 is deeper, which can better block the material in the lateral direction and prevent the material from sliding out when the device moves as a whole.

[0034] The upper material plate 1 is provided with a handle 5 for manual handling of the entire device. In the embodiment where the entire device is handled by a robot, the upper material plate 1 is provided with a positioning column 6 for cooperating with a gripping mechanism of a handling robot for the handling robot to grip and carry the entire device.
