Description

Technical Field

[0001] The utility model belongs to the technical field of plate cutting, and in particular relates to an automatic feeder for plate processing. Background Art

[0002] In the sheet metal processing industry, the feeding process is a key link in the production process. Since the sizes of sheets vary, the processing positions of the sheets are also different. However, the traditional feeding method is often difficult to adapt to the diverse production needs. It is impossible to automatically adjust the different feeding positions according to the size, shape, weight and other characteristics of the sheets. In order to ensure that the sheets can be prepared and sent to different processing equipment, they are generally manually lifted and moved to different feeding positions after being identified by the naked eye. However, this operation method has many disadvantages.

[0003] Firstly, some panels weighing more than 70 kilograms are almost equivalent to the weight of a normal adult. Such lifting work for a long time will undoubtedly cause serious damage to the workers' bodies. Secondly, this manual operation method not only has high labor costs, but also relatively low efficiency, which makes it difficult to meet the modern industrial production's demand for efficiency and speed.

[0033] In the utility model, the sub-frame 63 in the transmission section 5 is divided into an upper frame 631, a middle frame 632, a lower frame 633 and a bottom frame 634, and an articulated frame 61 is installed at the bottom of the sub-frame 63.

Not only does it not require too much labor cost, but it can also feed the plate quickly and accurately, thereby improving work efficiency.

[0034] Example 2

[0035] like Figures 1 to 7 An automatic feeder for plate processing shown in the figure includes a main frame 1, which is mainly used to undertake the installation of the wood board adsorption component and provide space for its forward and backward movement. The left and right sides of the top of the main frame 1 are connected with Y drive shaft 2 through a drag chain sliding connection, and then the Y drive shaft 2 can move forward and backward on the main frame 1. The Y drive shaft 2 is also connected with a gantry 3 through a drag chain sliding connection, and then the gantry 3 can move left and right on the Y drive shaft 2. The gantry 3 is also equipped with an adsorption grab plate 4, so that the adsorption grab plate 4 can move up and down on the gantry 3. The combination of the three can realize the XYZ three-axis movement of the adsorption grab plate 4, and flexibly adsorb and grab the plate at any position to cooperate with feeding. For grabbing the plate, a variety of methods can be selected, including but not limited to any one of a mechanical arm, a push rod, etc., and in the utility model, adsorption is specified as the best method. By controlling the suction force, the plate can be easily grabbed and released, and the plate can be quickly loaded. On this basis, sponge pads 18 are also installed at the two adsorption ends of the adsorption grab plate 4 to reduce the suction force when it is too strong, and the plate will directly hit the adsorption grab plate 4, causing damage to the surface of the plate, and even causing the thin wooden board to break directly.

[0036] Five placement areas 17 are provided on the ground at the right side below the main frame 1. The number of the placement areas 17 can be adjusted according to the actual situation of the user, and the adjustment values ​​include but are not limited to the following contents: the material, thickness and size of the board; and the five placement areas 17 in this embodiment are mainly for adapting to boards of different thicknesses and sizes. The user can place boards of different specifications in the placement areas 17 respectively, and the adsorption grab plate 4 moves in three axes above it, so as to adsorb and grab any required wooden board for loading.

[0037] Example 3

[0038] like Figures 1 to 7 An automatic feeder for plate processing shown in the figure includes a plurality of transmission sections 5, and the transmission section 5 has two bottom frames 6 and a transition frame. In the transmission section 5 closest to the main frame 1, the transition frame needs to be located below the main frame 1, and the other two bottom frames 6 are placed to the left close to the transition frame in sequence, that is, the placement positions from left to right are bottom frame 6, bottom frame 6, transition frame. When multiple transmission sections 5 are placed, they can be placed in a more detailed manner according to the above sequence. Then, the adsorption grab plate 4 will grab the plate and move it to the transition frame. The top of the transition frame is driven by a transmission cylinder 13 through a second motor 14. The transmission cylinder 13 rotates to transfer the upper plate to the left, and then passes through the top of the bottom frame 6 to complete the front and rear or straight-through feeding; therefore, the department that receives the plate can be installed on the front and rear sides of the bottom frame 6 to receive the plate.

[0039] A top plate 62 is installed on the top of the bottom frame 6 through an articulated frame 61. The top of the top plate 62 can be used for the plate to pass through. The stretching of the articulated frame 61 can drive the top plate 62 to move up and down. Compared with the common horizontal movement, the articulated frame 61 can provide a more stable moving force to avoid the deviation and shaking caused by the overweight of the plate, which leads to the uneven transmission height of the transmission section 5 and the inability to transmit. The bottom frame 6 can be automatically stretched by installing driving components such as electric cylinders. The mounting end of the electric cylinder is hingedly set on the bottom frame 6, and the output end is connected to the top plate 62, so that the effect of driving the electric cylinder to drive the top plate 62 to move up and down can be achieved. A sub-frame 63 is provided on the top plate 62. When the articulated frame 61 is at the lowest height (i.e., not stretched), the height of the sub-frame 63 will be flush with the transition frame, and then the transmission cylinder 13 on the transition frame will rotate to directly transmit the plate to the left to the sub-frame 63, completing the action of continuing transmission.

[0040] Among them, the sub-frame 63 is divided into 4 layers in total, which are divided into an upper frame 631, a middle frame 632, a lower frame 633 and a bottom frame 634 from top to bottom. Except for the bottom frame 634, the other 3 frames, the upper frame 631, the middle frame 632 and the lower frame 633 are connected with the same number of rollers 8, and the rollers 8 at the same horizontal position are connected by a sprocket assembly 9, and the sprocket assembly 9 is driven by the first motor 10, that is, the first motor 10 can drive the rollers 8 to rotate synchronously through the sprocket assembly 9, and then continue to transmit the received plate to the left.

[0041] Example 4

[0042] Embodiment 3 proposes that when the articulated frame 61 is not stretched, the upper frame 631 of the sub-frame 63 is flush with the transition frame, and then the transmission cylinder 13 on the transition frame rotates to directly transmit the plate to the left to the roller 8 of the upper frame 631, and the first motor 10 drives the roller 8 to rotate to continue to transmit the plate; that is, when the articulated frame 61 is continuously stretched until the middle frame 632 and the lower frame 633 of the sub-frame 63 are flush with the transition frame in turn, the plate can also continue to be transmitted to the left through the corresponding roller 8, providing multiple routes. Based on the above, this embodiment is provided with secondary transmission components on the upper frame 631 and the lower frame 633, that is, the plates through the upper frame 631 and the lower frame 633 can be transmitted and fed forward or backward respectively, so that the staff does not need to manually lift the wooden board for feeding, reducing labor costs. The specific settings are as follows:

[0043] 1. A first mounting frame 110 is extended from the middle of the bottom frame 634, and a first guide rail 111 is symmetrically provided on the top of the first mounting frame 110. A first transmission frame 112 is slidably connected between the tops of the first guide rails 111, and two first driving belts 113 are connected between the first transmission frames 112; a first cylinder 114 is provided on the inner rear side of the first transmission frame 112, and an output end of the first cylinder 114 is connected to the front side of the first mounting frame 110.

[0044] 2. A second mounting frame 120 is provided on the top of the middle frame 632, and a second guide rail 121 is symmetrically provided on the top of the second mounting frame 120. A second transmission frame 122 is slidably connected between the tops of the second guide rails 121, and two second driving belts 123 are connected between the second transmission frames 122. A second cylinder 124 is provided on the inner front side of the first transmission frame 112, and the output end of the second cylinder 124 is connected to the rear side of the second mounting frame.

[0045] In summary, the height of the first transmission frame 112 is flush with the lower frame 633, and the height of the second transmission frame 122 is flush with the upper frame 631, that is, the position of the middle frame 632 after the articulated frame 61 is stretched must be flush with the transition frame, so that the plates that do not need to be transported forward and backward in the transmission section 5 can continue to be transported to the left. That is, the plates on the middle frame 632 will be transported to the left, the plates on the lower frame 633 will be transported forward, and the plates on the upper frame 631 will be transported backward. To better demonstrate the transmission effect, two plates can be used for illustration:

[0046] The multiple transmission sections 5 can be divided into A, B, C, etc. from left to right, and the two sub-frames 63 in the transmission section 5 can be divided into A1 and A2, and so on. In this embodiment, the two articulated frames 61 can be stretched and controlled in advance according to the direction and orientation of the two woods to be moved, thereby obtaining at least the following eight transmission modes:

[0047] 1.A1 (backward), A2 (backward)

[0048] 2.A1 (left), A2 (backward)

[0049] 3.A1 (forward), A2 (backward)

[0050] 4.A1 (backward), A2 (left)

[0051] 5.A1(left), A2(left)

[0052] 6.A1 (forward), A2 (left)

[0053] 7.A1 (backward), A2 (forward)

[0054] 8.A1(forward), A2(forward)......

[0055] It can be seen from the above arrangement that the present embodiment can separately transport two plates at one time, complete the transmission of all optional options in the required direction, feed the plates quickly and accurately, and improve work efficiency.

[0056] Example 5

[0057] like Figures 1 to 7 The automatic feeder for plate processing shown in the figure has a first mounting frame 110 extending from the middle of the bottom frame 634, a first guide rail 111 symmetrically arranged on the top of the first mounting frame 110, a first transmission frame 112 slidably connected between the tops of the first guide rails 111, and two first drive belts 113 connected between the first transmission frames 112; a first cylinder 114 is arranged on the inner rear side of the first transmission frame 112, and the output end of the first cylinder 114 is connected to the front side of the first mounting frame 110. A second mounting frame 120 is also arranged on the top of the middle frame 632, a second guide rail 121 symmetrically arranged on the top of the second mounting frame 120, a second transmission frame 122 slidably connected between the tops of the second guide rails 121, and two second drive belts 123 are connected between the second transmission frames 122; a second cylinder 124 is arranged on the inner front side of the first transmission frame 112, and the output end of the second cylinder 124 is connected to the rear side of the second mounting frame.

[0058] That is, the utility model detects different specifications of the plates in advance by using the induction sheet and the predetermined program, and sends the required transmission direction information to the program. The program then controls the electric cylinder to drive the top plate 62 to move up and down, and the two articulated frames 61 will be stretched and fixed in advance. When the two plates need to realize the transmission actions of A1 (backward) and A2 (backward) in the transmission section, there is no need to drive the electric cylinder. The wooden board on the transition frame will automatically be transmitted to the roller 8 of the upper frame 631 to the left. When the induction sheet detects that the wooden board has all moved to the roller 8, the corresponding first motor 10 is stopped, so that the wooden board no longer moves to the left; at the same time, the two second cylinders 124 are driven to drive the second transmission frame 122 to move backward on the second guide rail 121, and then the second drive belt 123 is used to drive the wooden board to move backward. After all are moved out, the second drive belt 123 will be aligned with the rear receiving plate, and then the second drive belt 123 is operated to drive the wooden board to continue to be transmitted backward and move to the receiving plate, completing the synchronous backward transmission of the two plates.

[0059] When the plate does not need to be transferred forward and backward in the transmission section, two electric cylinders are driven to drive the middle frame 632 to align with the transition rack. The wooden board on the transition rack will be automatically transferred to the left to the roller 8 of the middle frame 632, and then the roller 8 rotates to drive the plate to continue to move to the left until the plate moves to the transition rack on the transmission section 5B for the next step.

[0060] When the two boards realize the transmission actions of A1 (forward) and A2 (forward) in the transmission section in turn, the driving electric cylinder drives the lower frame 633 to move upward to align with the transition rack, and then the boards on the transition rack will be transferred to the left to the roller 8 of the lower frame 633. When the sensor detects that all the boards have moved onto the roller 8, the corresponding first motor 10 is stopped, so that the wooden board no longer moves to the left; at the same time, the two first cylinders 114 are driven to drive the first transmission frame 112 to move forward on the second guide rail 121, and then the wooden board is driven forward by the first driving belt 113. After all the boards are moved out, the first driving belt 113 will be aligned with the front receiving plate, and then the first driving belt 113 operates to drive the wooden board to continue to be transmitted forward and move to the receiving plate, thereby completing the synchronous forward transmission of the two boards.

[0061] In summary, the corresponding electric cylinder drives the corresponding sub-frame 63 to move up and down, and then drives the rollers 8 at different heights to align with the transition frame, and cooperates with the subsequent preparatory work in different transmission directions. The forward transmission drives the lower frame 633 to align with the transition frame, the backward transmission drives the upper frame 631 to align with the transition frame, and the left transmission drives the middle frame 632 to align with the transition frame. The corresponding directions can be used to realize the transmission of plates in different directions, quickly and accurately feed the plates, and improve work efficiency.

[0062] Example 6

[0063] Furthermore, it also includes a limiting component. Since the specifications of the required transmission plates are different, including different thicknesses and widths, when the plates reach a certain thickness, that is, the plates themselves reach a certain weight, they are easily affected by the inertia of the transmission cylinder 13 and the roller 8. When the movement stops and prepares to be transmitted forward and backward, the plates can easily continue to move to the left under the influence of inertia, or even directly move out of the corresponding sub-frame 63. Therefore, a limiting component is set on the top left side of the upper frame 631 and the lower frame 633, which is specifically divided into a micro cylinder 15 and a limiting wheel 16. The limiting wheel 16 is hinged at the right side of the micro cylinder 15.

[0064] The micro cylinder 15 is symmetrically arranged at the top of the upper frame 631 and the lower frame 633, and is controlled by the information sent by the sensor sheet. When the micro cylinder 15 detects that the upper frame 631 and the lower frame 633 have entered the plate, the micro cylinder 15 automatically operates to drive the output end to move upward, and then pushes the limiting wheel 16 to rotate to different heights to block and limit plates of different sizes; the setting of the limiting wheel 16 can also reduce the impact force between it and the plate and reduce the loss of the plate. After completing the front and rear transmission of the plate, the micro cylinder 15 automatically resets and drives the limiting wheel 16 to reset.

[0065] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
