Description

Technical Field

[0002] After the production of stainless steel plates with a certain thickness is completed, they are stacked and placed, and then transferred to the subsequent processing position for processing, such as surface engraving, punching, or other processing. Since the stainless steel plates have a certain thickness, especially for stainless steel plates with smooth surfaces, their surfaces cannot be scratched. Therefore, they cannot be stacked from bottom to top. They are generally placed on a material rack and placed on the material rack from bottom to top. In this way, in order to place more stainless steel plates on the material rack, the distance between adjacent stainless steel plates will be set smaller. Generally, a forklift will move the material rack with stainless steel plates to the vicinity of the processing position. When taking materials, they are generally taken manually and placed at the subsequent processing position for processing. In this way, the feeding efficiency is relatively low, and the material is generally taken from top to bottom during the material taking process.

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0030] Example 1: See Figure 1-5 As shown, a stainless steel plate feeding device comprises:

[0031] Rack 1;

[0032] A feeding mechanism, the feeding mechanism is installed on the frame 1, the feeding mechanism comprises an upper conveyor belt 2 and a lower conveyor belt 3, the upper conveyor belt 2 is arranged directly above the lower conveyor belt 3;

[0033] A material receiving mechanism, the material receiving mechanism is installed on the frame 1, and the material receiving mechanism is arranged on the left side of the feeding mechanism; the material receiving mechanism comprises a material receiving conveyor belt 4 and a vertical driving mechanism for driving the material receiving conveyor belt 4 to move vertically;

[0034] A feeding cylinder 5, the feeding cylinder 5 is installed on the frame 1, the feeding cylinder 5 is fixedly installed between the upper conveyor belt 2 and the lower conveyor belt 3, and the feeding cylinder 5 is arranged close to the bottom of the upper conveyor belt 2, a push rod 6 is arranged on the output shaft at the left end of the feeding cylinder 5, when the output shaft of the feeding cylinder 5 is retracted, the left end of the push rod 6 is retracted below the upper conveyor belt 2, and when the output shaft of the feeding cylinder 5 is extended, the left end plane of the push rod 6 is arranged on the left side of the left end plane of the receiving conveyor belt 4;

[0035] The material frame 7 is provided with a plurality of discharge positions 8 from bottom to top, and the two ends of the discharge positions 8 are respectively connected with the left side and the right side of the material frame 7, and the upper conveyor belt 2, the lower conveyor belt 3 and the material receiving conveyor belt 4 are used for conveying the material frame 7.

[0036] In this embodiment, the stainless steel plate will be placed in the discharge position of the material frame, and a stainless steel plate will be placed in each discharge position, and multiple discharge positions are arranged in sequence from bottom to top. In actual use, the material frame with the stainless steel plate is placed on the right side of the lower conveyor belt, and is transported to the left by the lower conveyor belt. In the initial state, the top surface of the receiving conveyor belt and the top surface of the lower conveyor belt are set flush, and then the lower conveyor belt transports the material frame to the left, so that one material frame is transported to the receiving conveyor belt (at this time, the top surface of the receiving conveyor belt moves to the left), and then the vertical drive mechanism drives the receiving conveyor belt with the material frame to move upward, so that a discharge position is opposite to the push rod, and then the output shaft of the feeding cylinder (the driving cylinder uses a hydraulic cylinder or a pneumatic cylinder or an electric cylinder) extends, so that the push rod pushes the stainless steel plate to move to the left to leave the discharge position and enter the processing equipment on the left (or its The vertical drive mechanism drives the receiving conveyor belt to rise, so that the top surface of the receiving conveyor belt is flush with the top surface of the upper conveyor belt. The top surface of the receiving conveyor belt moves to the right at this time, and the empty material frame is transported to the upper conveyor belt to the right, and the upper conveyor belt is used to send the material frame to the right. Then the receiving conveyor belt moves downward, so that the top surface of the receiving conveyor belt is parallel to the top surface of the lower conveyor belt, and waits for the lower conveyor belt to send the material frame with the stainless steel plate to the receiving conveyor belt. This cycle is repeated to achieve automatic feeding.

[0037] The lower conveyor belt transmits the material frame placed on the lower conveyor belt from right to left, and the upper conveyor belt transmits the material frame placed on the upper conveyor belt from left to right.

[0038] In this embodiment, when the material frame on the lower conveyor belt needs to be sent to the receiving conveyor belt, the top surface of the receiving conveyor belt moves from right to left until the material frame moves to the receiving conveyor belt, and then the receiving conveyor belt pauses, so that the material frame does not move on the receiving conveyor belt. When the material frame needs to be sent to the upper conveyor belt, the top surface of the receiving conveyor belt moves from left to right to send the material frame to the upper conveyor belt.

[0039] See also Figure 5 As shown, a support member 9 is respectively provided on the front and rear sides of the material frame 7, a plurality of front support grooves 10 are provided on the rear side wall of the front support member 9, and a plurality of rear support grooves 11 are provided on the front side wall of the rear support member 9, the front support grooves and the rear support grooves are arranged at intervals from bottom to top, each of the front support grooves is arranged opposite to the rear support groove, and one front support groove and one of the opposite rear support grooves constitute a material discharge position.

[0040] In this embodiment, the height of the discharge position will be greater than the thickness of the product. Therefore, the front and rear sides of the bottom of the product are in contact with the discharge position, which will not scratch the product. More preferably, a rubber or cloth protective layer is provided on the inner wall of the front support groove and the rear support groove to prevent scratching the stainless steel plate.

[0041] In this embodiment, the front support member includes two front support columns spaced apart from each other, a plurality of front notches are arranged on the rear wall of each of the front support columns, the plurality of front notches are spaced apart from bottom to top, the front notches on the two front support columns correspond to each other, and the corresponding front notches on the two front support columns constitute a front support groove, and the rear support member includes two rear support columns spaced apart from each other, each rear support column is arranged at the rear side of a front support column, a plurality of rear notches are arranged on the front wall of each of the rear support columns, the plurality of rear notches are spaced apart from bottom to top, the rear notches on the two rear support columns correspond to each other, and the corresponding rear notches on the two rear support columns constitute a rear support groove. Each front notch on each front support column is arranged directly opposite to each rear notch on the rear support column directly behind it.

[0042] In this structure, the support parts use less material, which is equivalent to using four support columns to support the four corners of the stainless steel plate, which uses less material and is more cost-effective.

[0043] A limit plate 12 is provided on the right side of the support member 9, and the limit plate is located on the right side of the corresponding front support groove and rear support groove, so as to prevent the stainless steel plate from moving to the right and out of the discharge position, so that the stainless steel plate can only move to the left and out of the discharge position.

[0044] See also Figure 2 , 4 As shown, the vertical driving mechanism includes a vertical guide rod 13, a vertical lead screw 14, a vertical driving member 15 and a bracket 16. The vertical guide rod 13 is arranged parallel to the vertical lead screw 14. The top and bottom of the vertical guide rod 13 are respectively fixedly connected to the frame 1. Both ends of the vertical lead screw 14 are rotatably connected to the frame 1. The vertical driving member 15 drives the vertical lead screw 14 to rotate.

[0045] The rear end of the bracket 16 is slidably disposed on the vertical guide rod 13, and the vertical lead screw 14 is connected to the bracket 16. When the vertical lead screw 14 rotates, the bracket 16 is driven to move vertically along the vertical guide rod 13, and the material receiving conveyor belt 4 is installed on the bracket 16. The material receiving conveyor belt 4 is installed on the bracket 16 via a bracket 17.

[0046] In this embodiment, the rear end of the bracket moves vertically on the vertical guide rod, and the vertical driving member adopts a vertical motor, which drives the vertical lead screw to rotate. Since the vertical lead screw and the support plate are screwed, when the vertical lead screw rotates in one direction, it will drive the support plate to move upward along the vertical guide rod, thereby driving the material receiving conveyor belt and the material frame above it to move upward, so that each stainless steel plate is arranged opposite to the push rod, and the push rod can push the product out of the material frame. When the vertical lead screw rotates in another direction, it will drive the support plate to move downward along the vertical guide rod, thereby driving the material receiving conveyor belt to move downward, and realizing the up and down movement of the material receiving conveyor belt.

[0047] See also Figure 4 As shown, a limit cylinder 18 is provided on the front and rear sides of the left end of the bracket 16, and a limit member 19 is provided on the output shaft at the inner end of each limit cylinder 18; when the output shaft of the limit cylinder is extended, the limit member moves to the top of the material receiving conveyor belt, and when the output shaft of the limit cylinder is retracted, the inner end of the limit member moves to the outside of the material receiving conveyor belt.

[0048] A positioning hole 20 is respectively provided on the front side and the rear side of the left end of the material frame 7. When the output shaft of the limiting cylinder extends, the limiting member is inserted into the corresponding positioning hole; when the output shaft of the limiting cylinder retracts, the limiting member is separated from the positioning hole.

[0049] In this embodiment, when the lower conveyor belt conveys the material frame loaded with the stainless steel plate to the left, the top surface of the material receiving conveyor belt will also be conveyed to the left, so that the material frame entering the material receiving conveyor belt will also be conveyed to the left. In this process, after it moves to the predetermined position, the material receiving conveyor belt no longer continues to drive the material frame to convey to the left, and it needs to drive the material frame to move upward so that the push rod can push the stainless steel plate to move to the left and away from the material frame. In the process of the material receiving conveyor belt moving upward and the push rod pushing the stainless steel plate to move to the left and away from the material frame, in order to prevent the material frame from falling from the material receiving conveyor belt and ensuring the safety and stability during the working process, a limit piece and a positioning port are also provided. After the material frame is completely on the material receiving conveyor belt, the limit piece is opposite to the positioning port, and then the output shaft of the limit cylinder extends out, driving the limit piece to be inserted into the positioning port, and the material frame is limited by the limit piece and the positioning port. In this way, when the material receiving conveyor belt drives the material frame to move upward and the push rod pushes the stainless steel plate to move leftward and away from the material frame, the material frame can be stably placed on the material receiving conveyor belt, ensuring stability and safety during the feeding process. More preferably, a front side plate and a rear side plate are respectively provided on the front and rear sides of the bracket to prevent the material frame from moving forward and backward and away from the material receiving conveyor belt.

[0050] See also Figure 4As shown, the stopper is a tapered structure with a small inside and a large outside. With the tapered structure, even if the positioning port is not completely opposite to the stopper, there is a slight offset in the material frame. When the output shaft of the stopper cylinder is extended, the inner end of the stopper will be inserted into the positioning port. When the stopper continues to move inward, part of the outer surface of the stopper will contact the inner wall of the positioning port. At this time, the stopper continues to move inward, and will squeeze the positioning port through the tapered structure, and drive the material frame to move synchronously for a certain distance until the stopper is inserted into the positioning port. When the output shaft of the stopper cylinder is fully extended, the stopper is in the positioning port, the outer edge of the stopper close to the outer end surface is in the positioning port, and the outer end of the stopper is outside the positioning port. Therefore, when the material frame needs to be released from the limit, when the output shaft of the stopper cylinder retracts and drives the stopper to move outward, the stopper will not be stuck by the positioning port, ensuring that the stopper is separated from the material frame. After all the stainless steel plates in the material frame are pushed away from the material frame, when the top surface of the receiving conveyor belt is flush with the top surface of the upper conveyor belt, the output shaft of the limit cylinder retracts, driving the limit part to disengage from the limit opening. At this time, the top surface of the receiving conveyor belt moves to the right, driving the empty material frame to move to the right, disengage from the receiving conveyor belt, and move to the upper conveyor belt.

[0051] The frame 1 is also provided with a photoelectric sensor, which is arranged directly above the left end of the lower conveyor belt 2.

[0052] Multiple material frames will be placed on the lower conveyor belt at the same time, while the receiving conveyor belt can only hold one material frame at a time. Therefore, the lower conveyor belt conveys intermittently. After a material frame is sent to the receiving conveyor belt, when another material frame on the right moves to the left end of the lower conveyor belt, the photoelectric sensor will detect the material frame. At this time, the lower conveyor belt will temporarily stop working and the material frame will not be transported to the left. After the receiving conveyor belt is empty, it will transport another material frame to the left to the receiving conveyor belt, and the cycle will continue.

[0053] See also Figure 1-3 As shown, a baffle 21 is provided at the right end of the upper conveyor belt 2 .

[0054] In this embodiment, a robot arm can be set above the upper conveyor belt, and a baffle can block the material frame from being conveyed to the right. The empty material frame can be grabbed by the robot arm. In this way, there is no need to set an upper conveyor belt that is too long, thereby reducing space occupancy.

[0055] In the present invention, the upper conveyor belt, the lower conveyor belt and the material receiving conveyor belt are all provided with corresponding motor drives and transmissions.
