Description

Technical Field

[0001] The invention relates to the field of stainless steel plate production and processing, and in particular to a material frame and a feeding device. Background Art

[0002] After the production of stainless steel plates with a certain thickness is completed, they are stacked and placed, and then transported to the subsequent processing location for processing, such as surface engraving, punching, or other processing. For stainless steel plates with smooth surfaces, their surfaces cannot be scratched. Therefore, in the conventional method, a layer of protective film or a layer of protective pad is placed between adjacent stainless steel plates, and then stacked to reduce space occupation. This method is suitable for relatively thin stainless steel plates. For stainless steel plates with thicker thickness and heavier weight, this method is not very suitable, because their weight is relatively large, and it is difficult to suck the stainless steel plate with a suction cup. It can only be pushed to move, which is easy to scratch the stainless steel plate on the lower layer. In this method, the material rack is used for material placement. In this method, multiple layers are set on the material rack, and multiple stainless steel plates are placed on each layer. The size of the material rack is large, and the cost is relatively high. In addition, due to the large number of stainless steel plates placed, the material rack has a large load-bearing capacity and is easy to deform. When placing the stainless steel plate into the material frame or taking the stainless steel plate out of the material, the operator manually operates it or uses a robot to clamp the edge of the stainless steel plate to take the material. It cannot be directly transported or taken out by the conveyor belt. The material rack can only be moved by a forklift, which is very inconvenient. Summary of the invention

DETAILED DESCRIPTION

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0032] Example 1: See Figure 1-3 As shown, a material frame, a cavity 2 is provided in the middle of the material frame 1, and two ends of the cavity 2 are respectively connected to the left side and the right side of the material frame 1;

[0033] A support member 3 is respectively provided on the front side wall and the rear side wall of the cavity 2, a plurality of front support grooves 4 are provided on the rear side wall of the front support member 3, and a plurality of rear support grooves 5 are provided on the front side wall of the rear support member 3, the front support grooves 4 and the rear support grooves 5 are arranged at intervals from bottom to top, and each of the front support grooves 4 is arranged opposite to a rear support groove 5;

[0034] A positioning opening 6 is respectively provided on the front side and the rear side of the left end of the material frame 1 .

[0035] In the present embodiment, the material frame 1 comprises a top frame 7, a bottom frame 8 and four columns 9, the top frame and the bottom frame are hollow structures, the tops of the four columns are connected to the top frame, the bottoms are connected to the bottom frame, two columns are arranged forward, and two columns are arranged backward, the front support is installed on the rear side wall of the two front columns, the rear support is installed on the rear side wall of the two rear columns, and the positioning port is arranged on the bottom frame. In this structure, the structure of the material frame is simple, the material is small, and the cost is low. The front end of each stainless steel plate is placed in a front support groove, and the rear end is placed in a rear support groove. In this way, only the two sides need to support the stainless steel plate, and at the same time, the bottom of the front support groove and the rear support groove are used to support the bottom two sides of the stainless steel plate. In this way, it is convenient to take and put the stainless steel plate, and there is a certain gap between the two support members. The height of the front support groove and the rear support groove will be greater than the thickness of the stainless steel plate, which is convenient for taking and putting the stainless steel plate. The positioning port allows the material frame to be positioned when the stainless steel plate is placed into or taken out of the material frame. This ensures the stability of the material frame during the process of taking and placing the stainless steel plate, prevents it from tipping over, and reduces safety hazards.

[0036] See also Figure 1-3 As shown, a limiting plate 10 is provided at the right end of each support member 3, and each limiting plate 10 is respectively arranged on the right side of the corresponding front support groove 4 and rear support groove 5. The setting of the limiting plate enables the stainless steel plate to be placed into the front support groove and rear support groove of the material frame only from the left side of the material frame to the right, and its right end can be limited by the limiting plate to prevent it from falling out of the right side of the material frame.

[0037] See also Figure 1 , 2 As shown, the positioning opening 6 is arranged near the bottom of the material frame 1 ; a hoisting opening 11 is also arranged on the material frame 1 above each positioning opening 6 , and the hoisting opening 11 is arranged near the top of the material frame 1 .

[0038] The setting of the lifting port can be used to lift the material frame. For example, when it is in the workshop, the two lifting ports can be hooked with a crane through two hooks to lift the material frame. Moreover, after the material frame is lifted, the entire center of gravity will cause the material frame to be tilted upward from left to right, that is, the lower right corner of the material frame is facing downward, and the upper left corner of the material frame is facing upward. In this way, all the stainless steel plates in the material frame are tilted downward from left to right, and the top and bottom of the stainless steel plates will be limited by the front support groove and the rear support groove, and the right end will be limited by the limit plate to ensure that the stainless steel plates will not fall out of the material frame, thereby ensuring stability during the lifting and moving process and that the stainless steel plates will not fall.

[0039] See also Figure 1 , 2As shown, the support member 3 includes two support columns 12 spaced apart from each other, and a plurality of notches 13 are respectively arranged on the inner side wall of each support column 12, and the plurality of notches 13 are spaced apart from bottom to top, and the plurality of notches 13 on the two front support columns 12 constitute a plurality of front support grooves 4, and the plurality of notches 13 on the two rear support columns 12 constitute a plurality of rear support grooves 5. A through groove is arranged in the middle of the support member, and the through groove separates the support member into two support columns, and the through groove also separates each front support groove and rear support groove into notches arranged on the corresponding support column.

[0040] In this embodiment, each support column is installed on the inner wall of a column, and the four notches of the four support columns support and limit the four corners of the stainless steel plate respectively. The limit plate will be located on the right wall of the right support column to limit the right side of the notch to prevent the right end of the stainless steel plate from falling to the right. In this embodiment, only the four corners of the stainless steel plate need to be supported and limited, which reduces the use of materials and reduces costs.

[0041] Wherein, a protective layer is provided on the inner wall of the front support groove and the rear support groove, and the provision of the protective layer can protect the stainless steel plate and prevent the stainless steel from being scratched.

[0042] See also Figure 4-6 As shown, the present invention further provides a feeding device, comprising a frame 20, a vertical guide rod 21, a vertical driving mechanism, a material receiving and conveying component 22 and a bracket 23, wherein the vertical guide rod 21 is mounted on the frame 20, the rear end of the bracket 23 is slidably disposed on the vertical guide rod 21, the material receiving and conveying component 22 is mounted on the bracket 23, and the vertical driving mechanism drives the bracket 23 to slide vertically along the vertical guide rod 21;

[0043] It also includes the material frame 1 mentioned above, the material frame 1 is placed on the top of the material receiving and conveying component 22, and the material receiving and conveying component 22 drives the material frame 1 to move left and right on the top of the material receiving and conveying component 22;

[0044] The material receiving and conveying component 22 is also provided with a limiting component, which is directly opposite to the positioning opening 6 , and the limiting component limits the material frame 1 on the material receiving and conveying component 22 via the positioning opening 6 .

[0045] In this embodiment, a conveyor belt can be arranged on the left or right side of the frame to convey the material frame loaded with stainless steel plates (or an empty material frame) to the material receiving and conveying component, and a manipulator or other mechanism (material taking and placing device) is used to take out the stainless steel plates in the material frame or put them into the material frame. When taking out the materials, the stainless steel plates are taken out from the left side of the material frame or put in. In order to ensure the stability and safety of material taking and unloading and improve the convenience of material taking and unloading, the height position of the material taking and unloading device is fixed at one position. Taking material taking from the material frame as an example, the conveyor belt transports the material frame from right to left to the material receiving and conveying component, and then the vertical drive mechanism drives the bracket, the material receiving and conveying component and the material frame to move upward, so that the uppermost stainless steel plate moves upward by one position, and then the material taking and unloading device, for example, adopts a cylinder and a push rod, the output shaft of the cylinder extends out, drives the push rod to move left, moves the uppermost stainless steel plate to the left and pushes it out of the material frame (then the cylinder drives the push rod to move right out of the material frame), enters the back-end process or other required mechanism, and then the vertical drive mechanism continues to drive the material receiving and conveying component to move upward by one position, and the lower stainless steel plate is opposite to the push rod, and then the cylinder continues to drive the push rod to extend, pushes the next stainless steel plate to move to the left and out of the material frame, and so on. The cycle continues until all the stainless steel plates in the material frame are pushed out. Another conveyor belt can also be set on the opposite side of the feeding side (if the feeding is on the right side, a discharge conveyor belt is set on the left side), and the pallet is moved down so that the material receiving conveying component faces the discharge conveyor belt, and then the empty material frame is sent away. Similarly, feeding the stainless steel plates into the material frame is the same step. The discharge device can feed the stainless steel plates into the material frame one by one, and then the material frame with the stainless steel plates can be sent away (the left side of the material frame can face the feeding direction). In order to ensure the stability of the material frame during the material loading and unloading process, the material frame will not tip over or move. Therefore, a limit assembly is also set. The limit assembly is inserted into the positioning port so that the material frame will not move during the material loading and unloading process, thereby ensuring the stability and safety of the material loading and unloading process.

[0046] See also Figure 4-6 As shown, the material receiving and conveying component 22 includes a bracket 24 and a conveyor belt 25 installed on the bracket 24. The bracket 24 is installed on the bracket 23. The bracket 24 is provided with a left transmission shaft 26, a right transmission shaft 27 and a driving motor 28. The conveyor belt 26 is wound around the left transmission shaft 26 and the right transmission shaft 27. The driving motor 28 drives the left transmission shaft 26 or the right transmission shaft 27 to rotate.

[0047] The limiting assembly includes two sets of limiting mechanisms, and the two sets of limiting mechanisms are respectively arranged at the front top and the rear top of the left end of the bracket 24.

[0048] In this embodiment, a conveyor belt is used, and a driving motor is used to drive the left transmission shaft or the right transmission shaft to rotate. When one of the transmission shafts rotates, it will drive the conveyor belt to drive, so that the top of the conveyor belt moves to the left or right, so that when the material frame is fed onto the conveyor belt, the conveyor belt drives all the material frames to move onto the conveyor belt, or the conveyor belt sends the material frame above it away from the conveyor belt. The limiting component uses two sets of limiting mechanisms. When the material frame is fully moved to the top of the conveyor belt, each set of limiting mechanisms is set opposite to a positioning port of the material frame, and then the limiting mechanism is inserted into the corresponding positioning port to limit the material frame on the conveyor belt, which is convenient for feeding and discharging. When the material frame is to be sent away, the limiting mechanism is separated from the positioning port, and the conveyor belt is transported, so that the material frame can be sent away from the conveyor belt.

[0049] Among them, a plurality of supporting rollers are rotatably mounted on the bracket between the left transmission shaft and the right transmission shaft, and the top and bottom surfaces inside the conveyor belt are on the top outer surfaces of the plurality of supporting rollers.

[0050] Since the material frame loaded with stainless steel plates has a certain weight, in order to ensure that the conveyor belt can smoothly support and transport the material frame and prevent it from deformation and damage, a number of support rollers are also provided to support the inside of the conveyor belt to ensure its load-bearing capacity, prevent the conveyor belt from deformation, and stably transport the material frame.

[0051] See also Figure 4-6 As shown, the limiting mechanism includes a limiting cylinder 29 and a limiting member 30, the outer end of the limiting member 30 is connected to the output shaft of the limiting cylinder 29, and the limiting member 30 is a conical structure with a small inner side and a large outer side. When the output shaft of the limiting cylinder 29 is retracted, the limiting member 30 is separated from the positioning port 6, and the inner end of the limiting member 30 is arranged above the bracket at the outer end of the conveyor belt 25;

[0052] When the output shaft of the limiting cylinder is extended, the limiting member is arranged directly above the conveyor belt, and the inner end of the limiting member is inserted into one of the positioning openings.

[0053] In this embodiment, the limiting member is a conical structure with a small inside and a large outside. If only a part of the positioning opening is facing the limiting member, when the output shaft of the limiting cylinder is extended, the inner end of the limiting member can be inserted into the positioning opening, and then squeeze the side wall of the positioning opening to push the material frame to move a little distance relative to it, until the output shaft of the limiting cylinder is fully extended, and most of the limiting member is inserted into the positioning opening to achieve the limitation of the material frame.

[0054] See also Figure 6As shown, the vertical driving mechanism includes a vertical lead screw 31 and a vertical motor 32. Both ends of the vertical lead screw 31 are rotatably connected to the frame 20. The vertical motor 32 is installed on the frame 20. The vertical lead screw 31 is arranged parallel to the side of the vertical guide rod 21. The middle part of the vertical lead screw 31 is screwed to the bracket 23. When the vertical lead screw 31 rotates, the bracket 23 is driven to move along the vertical guide rod 21.

[0055] The vertical motor drives the vertical screw to rotate. Since the vertical screw and the bracket are screwed together, when the vertical screw rotates, it can drive the bracket to move vertically along the vertical guide rod, thereby driving the bracket and the material receiving and conveying part to move to any height, making it convenient to feed the stainless steel plate into the material frame or take the stainless steel plate out of the material frame.
