Description

Technical Field

[0001] The invention relates to the technical field of plate production line transportation, and in particular to automatic feeding and conveying equipment for a plate production line. Background Art

[0002] In the sheet production line, automatic feeding and conveying equipment is a key device to ensure efficient and continuous production. In the prior art, the adsorption cylinder combined with the vacuum suction cup is generally used to realize the gripping and loading of the sheet. Its typical working process is: the suction cup is driven by the cylinder to descend to the surface of the sheet, and the vacuum generator is started to adsorb the sheet and then lift and transfer it to the conveyor. The conveyor is transported to the cutting area and cut into strips. During the cutting process, a limiting mechanism is also required to limit and fix the sheet being cut. After cutting into strips, manual assistance is required for unloading. Although this technical solution has realized basic automation, there are still the following significant problems in actual application: 1. Poor coordination between conveying and cutting: The conveyor line is long, and the movement rhythm of the conveyor and the cutting equipment is difficult to accurately match. Especially in high-speed production lines, delays in cutting start and stop result in uneven incisions or material waste.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] See also Figure 1 , Figure 2 and Figure 5, an automatic feeding and conveying device for a plate production line, comprising a base 1, the upper end of the base 1 is respectively a loading area, a cutting area and a unloading area from left to right, a pushing bracket 11 is arranged on the base 1 in the loading area, and a plurality of evenly distributed cutting tools 2 are arranged on the base 1 in the cutting area along the width direction; a positioning component 3 is arranged in the unloading area, close to the right side of the cutting tool 2, for positioning the cutting seam of the plate being cut; a resistance component 4 is arranged in the unloading area, close to the right side of the positioning component 3, and the plate pushes the resistance component 4 to move synchronously to the right during cutting; a pushing component 5 is arranged at the rear side of the unloading area, for pushing the cut plate for unloading; wherein the pushing component 5 comprises a supporting frame 50 fixedly connected to the rear side of the unloading area of ​​the base 1, a wedge block 51 cooperating with the positioning component 3 to release the positioning of the cutting seam, and a matching rack 52 cooperating with the resistance part 41 to release the resistance of the plate; the matching rack 52 is fixedly connected to the upper end of the supporting frame 50 located on the right side.

[0030] During operation, the plate is placed on the loading area of ​​the base 1. Existing correction mechanisms (not shown in the figure) are arranged on both sides of the loading area to prevent the plate transported to the cutting area from being easily offset due to inertia or vibration during transportation, resulting in cutting position deviation. The pusher bracket 11 is pushed along the length direction of the base 1 by an external drive. Here, it is explained that the pusher bracket 11 and the plate are in multi-point contact, and the contact points are staggered with the cutting tool 2. The plate is pushed to the cutting area until the leftmost side of the plate is completely cut, and the leftmost side of the plate is cut into multiple long strips. The side push stops at the position of the positioning component 3. At this time, the rightmost side of the plate synchronously pushes the resistance component 4 to the right side of the base 1. The resistance component 4 is also located on the right side of the pushing component 5 at this time, and will not interfere with the subsequent pushing of the pushing component 5; when the pushing component 5 pushes the cut plate from back to front, the corresponding wedge block 51 will cooperate with the positioning component 3 to move upward, and release the positioning component 3 from limiting the cutting seam of the plate. When the resistance component 4 moves and cooperates with the matching rack 52, it will drive the matching rack 52 to rotate a certain angle, thereby releasing the resistance limit on the plate.

[0031] See also Figure 1 and Figure 3 The positioning assembly 3 includes two mounting grooves 31 symmetrically opened on the base 1 and mounting columns 32 fixedly connected in the mounting grooves 31; a matching block 33 that moves up and down is slidably connected to the front and rear mounting columns 32; a supporting spring is fixedly connected between the matching block 33 and the mounting groove 31, and the supporting spring is sleeved on the mounting column 32; a limiting piece 34 is fixedly connected to the bottom end of the matching block 33 through a connecting bracket, and the limiting piece 34 is used to position the cutting seam; a fixing block 35 is fixedly connected to the right side of the matching block 33.

[0032] The positioning component 3 is set to limit the cutting seam formed between the plates cut into strips. It is explained here that the widest thickness of the limiting piece 34 is the same as the thickness of the cutting tool 2 and the width of the cutting seam of the plate, and the front side of the limiting piece 34 is a conical structure, which plays a guiding role when the rightmost side of the plate enters the limiting piece 34. Under the action of the supporting spring, the initial position of the limiting piece 34 at the bottom of the matching block 33 is close to the upper end surface of the base 1. Due to the long length of the plate, the cutting seam is limited after cutting. Under the limitation of the cutting tool 2 and the limiting piece 34, the cutting line of the plate can be kept in a straight line to avoid deviation during the cutting process.

[0033] See also Figure 1 and Figure 4 The resistance component 4 includes a resistance part 41 for resisting the upper end surface of the plate being cut, two sliding grooves 42 symmetrically opened on the base 1 in front and back, and a sliding bracket 43 that slides left and right in the sliding groove 42 through a slide rail; an auxiliary roller 431 is fixedly connected to the rear side of the sliding bracket 43, and the auxiliary roller 431 is used to assist the sliding bracket 43 in moving; the resistance part 41 includes a linkage frame 411 rotatably connected to the middle of the sliding bracket 43 through a rotating shaft, and one end of the rotating shaft passes through the rear side of the sliding bracket 43; a plurality of evenly distributed connecting frames 412 are fixed on the left side of the linkage frame 411, and sliding guide posts 413 with end covers slide up and down in the connecting frame 412, and an extrusion spring is fixedly connected between the end cover of the sliding guide post 413 and the connecting frame 412, and the extrusion spring is sleeved on the sliding guide post 413; a mounting base 414 fixedly connected to the bottom end of the sliding guide post 413, and at least two pressing rollers 415 are rotatably installed on the mounting base 414 , the axis of the clamping roller 415 is parallel to the reference plane of the base 1; a driving member 44 for driving the resistance part 41 to rotate is provided on the resistance part 41; the contact member 45 is arranged on the front side of the sliding bracket 43, and the contact member 45 is composed of a clearance groove 451 opened on the left side of the sliding bracket 43 and a contact plate 452 elastically connected in the clearance groove 451. A plurality of avoidance openings are opened on the contact plate 452, and the avoidance openings all correspond to the position of the limiting piece 46; the limiting piece 46 is also arranged on the front side of the sliding bracket 43, and the contact member 45 does not interfere with the limiting piece 46 when moving left and right. A pressure sensor (not shown in the figure) is connected to the rear side of the contact plate 452, and the pressure sensor is located in the clearance groove 451. The pressure sensor is electrically connected to the signal processor. An electromagnet (not shown in the figure) is provided at the leftmost side of the slide rail and the sliding bracket 43 is located at the slide rail position. The electromagnet is electrically connected to the controller, and the controller is electrically connected to the signal processor.

[0034] The setting of the resistance component 4 is to resist the right side and upper side of the cut plate, which can reduce the vibration of the wooden board during the cutting process and greatly reduce the impact of the vibration during cutting on the deviation of the plate. Under the joint action of the pushing bracket 11, the left and right sides of the plate can be tightened, and the cutting path of the plate is further controlled to be in a straight line. In the initial state, the plate does not contact the contact plate 452. At this time, the electromagnet adsorbs the sliding bracket 43 to the leftmost side of the slide rail. When the cut plate is pushed to the right, the clamping roller 415 is initially close to the upper end surface of the base 1 under the action of the extrusion spring. When the plate passes, it will be pressed against the upper end of the plate. When the plate continues to move to the right, it will resist the contact plate 452. The contact plate 452 receives the elastic pressure and moves into the give way groove 451. At the same time, the pressure is transmitted to the pressure sensor on the rear side, and then the sliding bracket 43 will move to the right in the slide rail. The auxiliary roller 431 rolls with the upper end of the base 1 to reduce the friction when the sliding bracket 43 moves.

[0035] The pressure sensor senses pressure and converts it into an electrical signal, thereby controlling the electromagnet system. Specifically, the plate contacts the contact plate 452 and presses the contact plate 452. The contact plate 452 transmits the pressure to the pressure sensor connected to the rear side, converts the physical pressure signal into an electrical signal, and the signal processor receives the signal output by the pressure sensor and converts the electrical signal into a digital signal for processing by the controller. The controller receives the processed pressure signal and sends a switch signal to the electromagnet. In this embodiment, upon receiving the pressure signal, the controller will control the electromagnet to cut off the power, and the sliding bracket 43 will lose the magnetic connection with the slide rail, and the plate will push the sliding bracket 43 to move to the right.

[0036] When the plate contacts the contact plate 452, the cutting seam on the right side of the plate corresponds to the position of the limiting piece 46 at the same time. The limiting piece 46 limits the multiple cutting seams. The limiting piece 46 is made of elastic rubber material. One is to reduce the vibration force generated by the cutting knife during cutting, and the other is to enable the limiting piece 46 to adaptively generate a certain bending when pushing the plate to be unloaded, so as to disengage from the limiting of the plate and not affect the pushed plate.

[0037] participate Figure 2 , Figure 4 and Figure 5The driving member 44 includes a transmission ring gear 441 fixedly connected to the rotating shaft of the linkage frame 411, and the transmission ring gear 441 is meshed with the matching rack 52 when it moves to the position of the matching rack 52; the pushing assembly 5 also includes a guide slide rail 53 fixedly connected symmetrically on the left and right sides of the support frame 50; a pushing block 54 is connected to the guide slide rail 53 for sliding back and forth; the front end of the pushing block 54 is connected to a pushing member 55 through a fixed rod; the pushing member 55 includes an L-shaped push plate 551 that slides back and forth, and a wedge block 51 is fixedly connected to the left front side of the upper end of the L-shaped push plate 551; a height limiting plate 552 is set below the horizontal section of the L-shaped push plate 551 by sliding up and down through a slide rod, and the height limiting plate 552 is threadedly connected to the L-shaped push plate 551 through an adjusting threaded rod 553, and the adjusting threaded rod 553 is rotatably connected to the upper end of the height limiting plate 552.

[0038] When the sheet is completely pushed to the unloading area, during this process, the transmission gear ring 441 will mesh with the matching rack 52, and the transmission gear ring 441 will drive the linkage frame 411 to flip until the clamping roller 415 does not exert a resisting force on the sheet, and the external drive is started to drive the pushing block 54 to push the pushing piece 55 forward. At the same time, the front end of the wedge block 51 will enter the bottom end of the fixed block 35. As the wedge block 51 continues to move forward, it will drive the fixed block 35 to move upward until the limit piece 34 is out of the cutting seam position, releasing the limit on the cutting seam of the sheet. The pusher 55 will push the cut plate to the front side of the base 1 for unloading. The pusher 55 can be adaptively adjusted to push plates of different thicknesses. Specifically, according to the thickness of the plate, the threaded rod 553 is rotated to adjust the distance between the height limit plate 552 and the bottom end of the L-shaped push plate 551, so that the bottom end of the height limit plate 552 can be clamped on the upper end of the plate during the pushing process. By adjusting the threaded rod 553 to adapt to plates of different thicknesses, it is ensured that the unloading push plate is in stable contact with the plate, which prevents slippage or tilting during the pushing process and increases the stability during pushing.

[0039] See also Figure 6 There is a cavity structure below the unloading area of ​​the base 1, the cavity is connected to the sliding groove 42, a reset member 6 is arranged in the cavity, the reset member 6 includes a connecting plate 61 fixedly connected to the lower section of the sliding bracket 43, and the pulling plate 62 is located in the cavity of the base 1; an electric push rod is fixedly connected to the left side of the cavity of the base 1; the output end of the electric push rod is fixedly connected to a pulling plate 62 that cooperates with the connecting plate 61.

[0040] After the cut plate is unloaded, the electric push rod is started, and the pulling plate 62 connected to the right side of the electric push rod will pull the connecting plate 61 to drive the sliding bracket 43 to move to the leftmost side of the slide rail, and the sliding bracket 43 is re-adsorbed by the electromagnet. During the movement to the left, the clamping roller 415 also returns to a vertical position with respect to the upper end surface of the base 1. After the cutting is completed, the reset member 6 pulls the sliding bracket 43 to the initial position through the electric push rod, and the clamping roller 415 automatically resets, thereby realizing efficient connection of the equipment's cyclic operation.
