DETAILED DESCRIPTION

[0025] The application will be further described below in combination with the drawings and examples.

[0026] As shown in Figure 1 , Figure 2 , Figure 3 The auxiliary rack system of the numerical control sawing machine of the application, which is prior art, comprises a sawing machine feeding rack 23, a sawing machine 24 and a sawing machine discharging rack 25 arranged along a sawing machine axis 20, the auxiliary rack system comprises a feeding storage rack, a discharging storage rack and a remaining material turnover system 21, the remaining material turnover system 21 is arranged along the sawing machine axis 20 and is connected with the sawing machine feeding rack 23 through a transition rack 22 to replace part of the original assembled sawing machine feeding rack, a remaining material frame 210 is arranged beside the remaining material turnover system 21, the transition rack 22 can also use a section of the original sawing machine feeding rack, the servo feeding control, sawing length control and the like can use the control system and electric control cabinet matched with the original numerical control machine tool, the feeding storage rack and the discharging storage rack are arranged on the same side of the sawing machine axis 20 to save the land width occupied by the whole sawing system;

[0027] The loading storage rack comprises two or more front storage racks 1 arranged along a first horizontal direction X parallel to the sawing machine axis 20, and the distribution length of the front storage racks 1 is adapted to the length from the excess material feeding system 21 to the sawing machine feeding rack 23, so that the loading storage rack can be adapted to the design and processing length of the numerical control sawing machine itself, and the closer to the sawing machine feeding rack 23, the smaller the spacing between the two adjacent front storage racks 1, thereby, using two or more front storage racks 1, the temporary storage of excess materials or materials to be sawed of various lengths can be adapted, and each front storage rack 1 is provided with a first chain belt conveying device 3 which can be translated along a second horizontal direction Y perpendicular to the first horizontal direction X, and the first chain belt conveying device 3 is equipped with a first chain belt power system 2, and the first chain belt conveying devices 3 on multiple front storage racks 1 temporarily storing the same material are synchronously operated in the same direction, so that the material can be conveyed to the position waiting to be conveyed to the sawing machine feeding rack, and each front storage rack 1 is also correspondingly provided with a lifting feeding device 5 which can transfer the material between the conveying plane of the first chain belt conveying device 3 and the conveying plane of the sawing machine feeding rack 23, and starting the lifting feeding device 5 can transfer the material from the conveying plane of the first chain belt conveying device 3 to the conveying plane of the sawing machine feeding rack 23, and vice versa.

[0028] The front end of the loading storage rack is provided with a length detection device 8 close to one side of the sawing machine axis 20, and the rear end of the loading storage rack is provided with a storage limiting device 6 and a material pushing alignment device 7 close to one side of the sawing machine axis 20, the storage limiting device 6 is provided with a vertical limiting surface 60 perpendicular to the sawing machine axis 20, when the crane hoists the profile raw materials and other materials to the front storage rack, the front end of the raw material should be close to the vertical limiting surface 60 as much as possible, because the width of the loading storage rack is multiple times greater than the width of the sawing machine feeding rack, the loading storage rack can temporarily store a batch of materials, thereby reducing the dependence on the crane, the material pushing alignment device 7 is provided with a vertical alignment plate 71 which can be horizontally extended forward from the plane where the vertical limiting surface is located to a certain distance, that is, the stroke range of the vertical alignment plate 71 is preferably from the plane where the vertical limiting surface 60 is located to the remote stop point away from the plane where the vertical limiting surface is located, and the other stroke stop point cannot obviously exceed the plane where the vertical limiting surface 60 is located, so as to avoid interference with the materials, and the other stroke stop point is selected on the plane where the vertical limiting surface 60 is located, so as to shorten the stroke and make the alignment more efficient. The vertical alignment plate 71 corresponds to the position of the length detection device 8, and the position is located at one end of the first chain belt conveying device 3 close to the sawing machine axis 20, that is, the position is the position for measuring the length of the materials and the position for waiting to convey the materials to the sawing machine feeding rack, that is, the "material loading position", the position of the detection device 8 is fixed, and the remote stop point position of the vertical alignment plate 71 is also fixed after being adjusted to the position, and the distance between the two is a certain value, therefore, the detection device 8 is used for detecting the distance between the end face of the materials away from one end of the vertical alignment plate 71 and the installation position of the detection device 8, and the length of the materials is obtained by subtracting the measured distance from the certain value, and the length is fed back to the numerical control machine tool, and the sawing operation of the materials is generated with automatic instructions according to the measured length of the materials and the required part length. In addition, it should be noted that the vertical alignment plate 71 can repeatedly hit the end of the materials for a short distance before reaching the remote stop point, so as to achieve a better "alignment" effect, but the vertical alignment plate 71 should reach the remote stop point after one alignment operation, so as to complete the length measurement, and the vertical alignment plate 71 returns to the plane where the vertical limiting surface 60 is located after the length measurement is completed. The vertical alignment plate 71 plays a role of "alignment" and "measurement reference" when a plurality of materials are sawed at the same time.

[0029] Obviously, in the application, the lifting structure of the lifting loading device is staggered with the material supporting structure of the sawing machine feeding rack in space, and does not affect the normal operation of the sawing machine feeding rack.

[0030] Similarly, a downstream unloading storage rack is arranged downstream of the sawing machine discharge rack, the unloading storage rack comprises two or more rear storage racks 9 arranged at intervals along a first horizontal direction X, each rear storage rack 9 is provided with a second chain belt conveying device 11 capable of translating along a second horizontal direction Y, the second chain belt conveying device 11 is equipped with a second chain belt power system 10, and each rear storage rack 9 is further provided with a lifting unloading device 13 corresponding thereto, the lifting unloading device 13 can transfer materials between the conveying plane of the sawing machine discharge rack 25 and the conveying plane of the second chain belt conveying device 11, when the sawing of a section of parts is completed, the parts can be transferred to the plurality of rear storage racks 9 by the lifting unloading device 13 for temporary storage, so as to prevent the sawing machine from stopping working due to the fact that the crane cannot timely lift the parts and the parts occupy the position of the sawing machine discharge rack 25. The lifting structure of the lifting unloading device and the material supporting structure of the sawing machine discharge rack are staggered in space, and do not affect the normal operation of the sawing machine discharge rack.

[0031] In the above design, the positions of the "butt joint" and "length measuring" devices are more reasonably designed, the crane can lift multiple batches of materials and store them on the feeding storage rack when idle, or use the crane or forklift to transfer the multiple batches of processed parts temporarily stored on the unloading storage rack to other workstations when idle, so as to reduce the dependence of the sawing machine on the timely response of the crane. When the length of the parts to be sawed is relatively long and exceeds the allowable length of the sawing machine discharge rack, the method of "sawing short and leaving long" can be used, according to the length of the material measured by the detection device 8, the length of the excess material is calculated as the length of the parts for sawing, and after sawing, the shorter part, i.e. the excess material, is output from the sawing machine discharge rack 25, and the longer part of the parts is returned to the excess material turnover system 21 position from the sawing machine 24 through the sawing machine feeding rack 23 and the transition material rack 22, and the turnover system is operated to act, and the long parts are turned over and dropped into the excess material frame 210 for temporary storage. The excess material which is shorter but longer than the allowable length of the sawing machine discharge rack is also returned to the excess material turnover system 21 position and turned into the excess material frame 210 for centralized storage, and the excess material and / or large-size material are lifted out when the crane is idle. With the action of the excess material turnover system 21 and the temporary storage function of the excess material frame 210, the excess long material and large-size material can be returned even when the crane is not idle, in order to prepare for the next sawing process. Therefore, the auxiliary rack system of the present application can cooperate with the numerical control machine tool to realize automatic feeding and unloading and excess material storage without dependence on the crane, reduce the lifting frequency and the labor intensity of the operator, effectively improve the labor productivity, make the production resources more effectively utilized, realize automatic sawing of the excess long parts, flexible production scheduling, and simple operation.

[0032] The excess material turnover system 21 can be designed by referring to the turnover mechanism on the existing profile conveying line, and a simple turnover mechanism is provided in the application. The excess material turnover system comprises a rack and a turnover plate installed on the rack. The turnover plate is a right-angled trapezoidal plate, one side of the right-angled waist of which is parallel to the transmission plane of the rack. In the non-turnover state, the turnover plate is parallel to and lower than the transmission plane of the rack. In this state, the turnover plate is switched to the turnover state by rotating 90 degrees, at which time the turnover plate is perpendicular to the transmission plane of the rack, and the oblique waist forms a guide slope and is higher than the transmission plane of the rack. The turnover plate rotating 90 degrees is a design that can be easily realized in the prior art. Thus, the excess material turnover system can also serve as a function of the feeding rack of the sawing machine. The turnover plates on multiple racks can be designed in linkage, and the gaps between the racks can be used for the arrangement of the lifting feeding mechanism. The excess material frame 210 is composed of two or more U-shaped racks with open top ends and is arranged in parallel with intervals. When the turnover is performed, the parts or excess materials automatically roll into the excess material frame 210 along the oblique waist of the turnover plate 212 under the action of gravity.

[0033] Further, as shown in Figure 2 and Figure 3 , the lifting feeding device 5 and the lifting discharging device 13 each comprise a sliding table 51, a lifting rod 52 installed on the sliding table 51, one end of the lifting rod 52 being hinged to the sliding table 51, a lifting device 53 being connected between the middle of the lifting rod 52 and the sliding table 51, and the other end of the lifting rod 52 being a lifting end 520, the lifting end 520 being provided with a limiting or anti-skid structure. The lifting feeding device 5 is equipped with a feeding power system 4, and the lifting discharging device 13 is equipped with a discharging power system 12, so as to complete the sliding and resetting actions of the lifting rod. The lifting device 53 of the lifting feeding device 5 can adopt a hydraulic cylinder and a matched hydraulic station due to the high load requirement, so as to complete the jacking and resetting actions. The lifting device 53 of the lifting discharging device 13 can adopt a motor and a common lifting mechanical structure due to the relatively low load requirement. The above structure is simple in operation, easy to automate, strong in carrying capacity, and long in service life.

[0034] The sliding table 51 is installed on the front storage rack 1 or the rear storage rack 9, so as to use the storage rack and the temporarily stored materials thereon as the counterweight of the sliding table 51 supporting the lifting rod 52, thereby increasing the stability and safety during the lifting feeding or discharging process.

[0035] In addition, a fence can be arranged around the rack system to increase the safety.

[0041] c. The lifting feeding device 5 is started, and the material to be sawed is transferred from the transmission plane of the first chain belt transmission device 3 to the transmission plane of the sawing machine feeding rack 23;

[0042] d. The sawing machine 24 is started, if necessary, the sawing end is cut, and the parts of the designed sawing length are cut to the set length, and the parts are sent to the sawing machine discharging rack 25;

[0044] The feeding work flow of the embodiment is as shown in Figure 2 .

[0045] Batch storage: the crane batch hoists the profile raw materials to the front storage rack 1, and the front end of the raw materials is placed as close to the vertical limiting surface 60 of the storage limiting device 6 as possible.

[0048] Lifting feeding: after the raw material is measured in length, the lifting feeding device 5 is started, and the raw material is lifted to a certain height, then the lifting feeding device 5 starts to translate, and the raw material is horizontally displaced above the sawing machine feeding rack 23, then the lifting end 520 is lowered, and the raw material is placed on the sawing machine feeding rack 23, and the lifting feeding device 5 starts to retreat and resets to the initial position.

[0051] Carrying parts: when the parts on the unloading storage rack are stacked to a large amount, the crane needs to start to hoist the sawed profile parts, or a forklift is used to carry the parts outside one end of the storage rack.

[0052] The feeding storage rack can realize batch initial storage, conveying of materials, flattening of the ends of bundled and scattered profiles, and measurement and lifting of feeding to the servo feeding system of the sawing machine.

Through information docking with the numerical control sawing bed electrical system, the electric control system can realize linkage, and after the operation mode is converted to automatic mode, automatic feeding and unloading can be completed according to the numerical control sawing bed feeding and discharging conditions, which can effectively improve the sawing efficiency, reduce the frequency of crane lifting and labor intensity, save manufacturing costs, and improve production efficiency.
