Description

TECHNICAL FIELD

[0001] The utility model relates to a cutting machine technical field, concretely relates to cutting machine's feeding device and cutting machine. BACKGROUND

[0002] The wood template processing numerical control machine tool, namely cutting machine, is mainly used for processing wood templates into specified shapes. The feeding device is a metal structural part device installed on the gantry of the cutting machine and integrated with the cutting machine. The feeding device is composed of a metal structural part and a grabbing part. The metal structural part is installed and fixed to the gantry of the cutting machine and moves with the gantry of the cutting machine, responsible for providing rigid support for the entire feeding device. The grabbing part includes a grabbing suction cup, a lifting cylinder and related accessories, installed and fixed on the metal structural part beam, responsible for grabbing and releasing raw materials.

[0003] Forklift feeding refers to placing neatly stacked templates on the automatic jacking device by a machine forklift or a manual forklift. The automatic jacking device is a standard hydraulic jacking device that can detect the current unprocessed raw material height and automatically jack up to the preset height when the height is insufficient.

[0004] In order to improve the working efficiency of the cutting machine, an automatic feeding device is used to complete the continuous cycle of feeding and processing. The automatic operation of the cutting machine is limited by the forklift feeding process. Increasing the number of boards per single feeding can improve the working efficiency of the cutting machine.

[0005] The feeding scheme in related technologies usually adopts ordinary traction feeding, which is fixed to the gantry of the cutting machine by a simple horizontal support, and the to-be-processed boards are lifted and dragged to the machine table by a short-stroke grabbing cylinder and a grabbing suction cup. The positioning device on the table is used to position the to-be-processed boards. Limited by the height of the gantry of the cutting machine, the maximum stacking height of single feeding in the forklift feeding process is about 75 cm. According to the standard board thickness of 1.5 cm, about 50 boards are fed per single time. In the construction industry, the number of original materials in a whole package of small templates is mostly 90, and the number of original materials in a whole package of large templates is 60. Therefore, at least two forklift feeding processes are required to process a whole package of original materials, and additional manual unpacking and neat stacking processes are required, increasing labor costs and time costs.

DETAILED DESCRIPTION

[0051] In order to make the purpose, technical scheme and advantages of the utility model embodiments clearer, the technical scheme in the utility model embodiments will be described clearly and completely below in combination with the drawings in the utility model embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0052] The wood template processing numerical control machine tool, referred to as cutting-off machine, is mainly used for processing wood templates into specified shapes. The feeding device is a metal structural part device installed on the gantry of the cutting-off machine and integrated with the cutting-off machine. The feeding device is composed of a metal structural part and a grabbing part. The metal structural part is installed and fixed to the gantry of the cutting-off machine and moves together with the gantry of the cutting-off machine, responsible for providing rigid support for the entire feeding device. The grabbing part includes a grabbing suction cup, a lifting cylinder and related accessories, which are installed and fixed on the metal structural part crossbeam and responsible for grabbing and releasing raw materials.

[0053] Forklift feeding refers to placing neatly stacked templates on the automatic jacking device by machine forklift or manual forklift during feeding. The automatic jacking device is a standard hydraulic jacking device that can detect the current unprocessed raw material height. When the height is not enough, it automatically jacks up to the preset height.

[0054] In order to improve the working efficiency of the cutting machine, an automatic feeding device is used to complete the continuous cycle of feeding and processing. The automatic operation of the cutting machine is limited by the forklift feeding process. Increasing the number of boards in a single feeding process can improve the working efficiency of the cutting machine.

[0055] The feeding scheme in the related art usually adopts ordinary traction feeding, which is fixed to the gantry of the cutting machine through a simple horizontal support, and the to-be-processed board is lifted on one side through a short-stroke grabbing cylinder and a grabbing suction cup, and is dragged to the machine table. The positioning device of the table positions the to-be-processed board. Limited by the height of the gantry of the cutting machine, the maximum stacking height of a single feeding process in the forklift feeding process is about 75 cm. According to the standard board thickness of 1.5 cm, about 50 boards are fed in a single feeding process. The whole package of the small formwork in the construction industry is mostly 90 raw materials, and the whole package of the large formwork is 60 raw materials. Therefore, at least two forklift feeding processes are required to process a whole package of raw materials, and additional manual unpacking and orderly stacking processes are required, which increases the labor cost and time cost.

[0056] Another feeding scheme in the related art is whole board feeding. The difference between this scheme and the traction feeding scheme is that the number of lifting cylinders and grabbing suction cups is increased in the transverse direction to ensure that the whole board is lifted simultaneously, avoiding board friction during transportation. In addition, a motion motor and a sliding block are additionally provided to complete the raw material transportation function. Compared with the traction feeding scheme, the optimization point is that the scratches on the board caused by the feeding process are reduced, and the defective rate of the finished product is reduced. The disadvantage is that the motion motor and the related control hardware are increased, and the modification cost is significantly increased. However, the whole board feeding scheme also does not support whole package feeding.

[0057] In the related art, whole package feeding by the forklift is realized by digging a pit on the flat ground to lower the horizontal plane of the automatic jacking device. However, most construction sites do not have the condition to dig a pit on the flat ground, and the construction cost is very high.

[0058] In addition, according to the production requirements, large-size formworks and small-size formworks need to be processed at different times on the same cutting machine, so the size of the board needs to be switched. The large-size formwork or the small-size formwork needs to be positioned by the positioning device. The positioning device includes a plurality of positioning cylinders and a pushing cylinder. The positioning cylinders are fixed on the edges and inside of the cutting machine table and are distributed in the transverse and longitudinal directions. They are responsible for providing a positioning reference point. When the board is close to the positioning cylinder column, it is considered to be accurately positioned. The pushing cylinder is fixed within a certain range outside the cutting machine table and is responsible for pushing the board on the table in the transverse and longitudinal directions in turn, so that the board is close to the positioning cylinder column to complete the positioning of the board.

[0059] The positioning device in the related art is installed on the edge of the machine table, so the same machine can only support one size of raw material size.

[0060] The following will be described in combination withFigures 1 to 8 The embodiment of the utility model discloses.

[0061] According to the embodiment of the utility model, on the one hand, a feeding device 1 of a cutting machine is provided, which comprises a fixed base 100, a first inclined support 101, a horizontal frame body, a cylinder support 102 and a lifting cylinder 103.

[0062] The fixed base 100 is adapted to be fixed on a portal frame 3 of the cutting machine.

[0063] The first end of the first inclined support 101 is connected to the fixed base 100, and the second end extends upwardly and obliquely.

[0064] The horizontal frame body is connected to the second end of the first inclined support 101.

[0065] The cylinder support 102 is fixed to the horizontal frame body, and the cylinder support 102 has a fixed end that is higher than the horizontal frame body.

[0066] The lifting cylinder 103 is fixed to the fixed end of the cylinder support 102, and the lifting cylinder 103 is connected to a grabbing suction cup.

[0067] In this embodiment, since the fixed base 100 is adapted to be fixed on the portal frame 3 of the cutting machine, when the fixed base 100 is fixed on the portal frame 3, it can move together with the portal frame 3. Since the first end of the first inclined support 101 is connected to the fixed base 100, and the second end of the first inclined support 101 extends upwardly and obliquely, the position of the second end of the first inclined support 101 is relatively high. The horizontal frame body is connected to the second end of the first inclined support 101, the cylinder support 102 is fixed to the horizontal frame body, the fixed end of the cylinder support 102 is higher than the horizontal frame body, and the lifting cylinder 103 is fixed to the fixed end of the cylinder support 102. Therefore, the height of the lifting cylinder 103 is relatively high, and compared with the related art, the position of the lifting cylinder 103 is raised, which is higher than the table surface 2 of the cutting machine, and the activity range of the grabbing suction cup is significantly improved. Therefore, the feeding height of the forklift can be increased to support whole package feeding.

[0068] Specifically, as shown in Figure 1 the fixed base 100 comprises a plurality of rectangular plates, and each rectangular plate is fixed to the portal frame 3 by screws.

[0069] Further referring to Figure 1 the fixed base 100 comprises four rectangular plates, the two rectangular plates near the edges are coplanar, the two rectangular plates in the middle are coplanar, and the installation positions of the two rectangular plates near the edges on the portal frame 3 are lower than the installation positions of the two rectangular plates in the middle.

[0070] In one embodiment, the distance between the lower end of the lifting cylinder 103 and the cutting machine table 2 is h, where h ≥ 90 cm.

[0071] In this embodiment, the lower end of the lifting cylinder 103 is 90cm or more above the cutting machine. The cutting machine itself can be customized so that the table 2 is 90cm above the ground. Therefore, the total height of the material-gripping suction cup of the loading device 1 from the ground can reach 180cm. The minimum height of the automatic lifting device 9 from the ground is 15cm. Thus, a forklift loading height of 180cm - 15cm = 165cm can be obtained. The rear leg of conventional sheet metal varies from 1.3cm to 1.8cm. Based on the maximum size, calculating with a full package of 90 sheets, the maximum height of the full package is 1.8 × 90 = 162cm. Therefore, by setting up this loading device 1, the forklift can load the entire package without adding extra unpacking costs or a secondary forklift loading action.

[0072] In a preferred embodiment, the distance between the lower end of the lifting cylinder 103 and the cutting machine table 2 is about 100cm, specifically 100cm.

[0073] like Figure 2 As shown, the lower end of the lifting cylinder 103 is 100cm higher than the cutting machine. The cutting machine itself can be customized so that the table 2 is 90cm above the ground. The total height of the material gripping suction cup of the loading device 1 from the ground can reach 190cm. The minimum height of the automatic lifting device 9 from the ground is 15cm. Therefore, a forklift loading height of 190cm-15cm=175cm can be obtained, which can meet the requirements of forklift loading of whole packages without adding extra unpacking costs and secondary forklift loading actions.

[0074] In one embodiment, the cylinder support 102 is inclined, with one end fixed to a horizontal frame and the other end extending upwards at an incline to form a fixed end.

The two first horizontal bars 104 and the two second horizontal bars 105 form a rectangular frame. The two ends of the crossbeam 106 are respectively connected to the first inclined support 101. One of the first horizontal bars 104 is connected to the fixed base 100 through a connector.

[0081] In one embodiment, the two ends of one first horizontal rod 104 are respectively connected with the fixed base 100 through connecting pieces.

[0082] In this embodiment, the two ends of one first horizontal rod 104 are respectively connected with the fixed base 100 through connecting pieces, the structure of the feeding device 1 is more stable, and the strength of the feeding device 1 is further improved.

[0088] Specifically in one embodiment, the fourth horizontal rod 110 is integrally arranged with the first inclined support 101.

Since the first end of the first inclined support 101 is connected with the fixed base 100, the second end of the first inclined support 101 extends obliquely upward, so the position of the second end of the first inclined support 101 is higher, the horizontal frame body is connected with the second end of the first inclined support 101, the cylinder support 102 is fixed on the horizontal frame body, the fixed end of the cylinder support 102 is higher than the horizontal frame body, and the lifting cylinder 103 is fixed on the fixed end of the cylinder support 102, so the height of the lifting cylinder 103 is higher. Compared with the related art, the position of the lifting cylinder 103 is raised, which is higher than the cutting machine table surface 2, and the activity range of the grabbing suction cup is significantly improved, so that the loading height of the forklift can be increased to support the whole bag loading.

[0097] In one embodiment, the cutting machine further comprises a positioning device, which comprises: a long-side positioning cylinder group 4, a short-side large-plate positioning cylinder group 5, a short-side small-plate positioning cylinder group 6, a long-side pushing cylinder 7, and a short-side pushing cylinder 8.

[0098] The long-side positioning cylinder group 4 is arranged on one side of the long side of the table surface 2; the short-side large-plate positioning cylinder group 5 is arranged on one side of the short side of the table surface 2; the short-side small-plate positioning cylinder group 6 is arranged on the table surface 2 and arranged along the width direction of the table surface 2, the table surface 2 is provided with a through hole, the cylinder column of the short-side small-plate positioning cylinder group 6 can pass through the through hole, and has a first position extending out of the table surface 2 and a second position retracted to the lower side of the table surface 2; the long-side pushing cylinder 7 is arranged on the gantry 3 and located on the other side of the long side of the table surface 2; and the short-side pushing cylinder 8 is arranged on the other side of the short side of the table surface 2.

[0099] In this embodiment, by setting a through hole on the table 2, the cylinder column of the short edge small plate positioning cylinder group 6 can pass through the through hole, and has a first position extending out of the table 2 and a second position retracting to the lower side of the table 2. When the large plate needs to be processed, the cylinder column of the short edge small plate positioning cylinder group 6 is retracted to the lower side of the table 2, and after the feeding device 1 stably grabs the plate, the gantry 3 is moved to the vicinity of the short edge large plate positioning cylinder group 5, the lifting cylinder 103 lowers the plate, the grabbing suction cup releases the plate, then the gantry 3 is moved to the center of the plate, and the long edge pushing cylinder 7 and the short edge pushing cylinder 8 are controlled to push the plate in turn, then the long edge pushing cylinder 7 and the short edge pushing cylinder 8 are simultaneously pushed to ensure that the plate is tightly attached to the long edge positioning cylinder group 4 and the short edge large plate positioning cylinder group 5, and positioning is completed. When the small plate needs to be processed, the cylinder column of the short edge small plate positioning cylinder group 6 is extended out of the table 2, and after the feeding device 1 stably grabs the plate, the gantry 3 is moved to the vicinity of the short edge large plate positioning cylinder group 5, the lifting cylinder 103 lowers the plate, the grabbing suction cup releases the plate, then the gantry 3 is moved to the center of the plate, and the long edge pushing cylinder 7 and the short edge pushing cylinder 8 are controlled to push the plate in turn, then the long edge pushing cylinder 7 and the short edge pushing cylinder 8 are simultaneously pushed to ensure that the plate is tightly attached to the long edge positioning cylinder group 4 and the short edge small plate positioning cylinder group 6, and positioning is completed. Therefore, the cutting machine can position large plates and small plates, and can realize size switching.

[0100] Specifically, in one embodiment, the installation position of the short edge pushing cylinder 8 is close to the edge 30 cm of the table 2, and the stroke is 30 cm. The pushing head of the long edge pushing cylinder 7 is 10 cm away from the long edge of the table 2, and the stroke is 40 cm, which ensures that the small plate can be pushed to the positioning column of the long edge positioning cylinder group 4.

[0101] It should be noted that the table 2 of the cutting machine has the function of adsorbing the plate, and the table 2 is provided with a vacuum pump suction hole. The position of the short edge small plate positioning cylinder group 6 needs to avoid the vacuum pump suction hole. The installation position of the short edge small plate positioning cylinder group 6 cannot be too far from the short edge of the cutting machine table 2, otherwise it will limit the grabbing space of the feeding device 1, and after exceeding the pushing cylinder stroke range, the pushing and positioning action cannot be completed, and positioning fails. The size of the through hole should be as small as possible to ensure that the cylinder column can pass through, otherwise air leakage will occur, which will reduce the overall adsorption raw material capacity of the cutting machine, and then affect the processing precision.

[0102] In one embodiment, the cutting machine comprises a control system and a recognition component, the control system is in communication connection with the recognition component, the short edge large plate positioning cylinder group 5 and the short edge small plate positioning cylinder group 6, and the recognition component can recognize the size of the plate grabbed by the grabbing suction cup.

[0103] In the embodiment, by setting the control system and the identification component, when the identification component identifies that the plate material grabbed by the grabbing suction cup is a large plate material, the control system controls the cylinder column of the short edge small plate positioning cylinder group 6 to retract to the lower side of the table 2, after the plate material is stably grabbed by the feeding device 1, the gantry 3 is moved, so that the gantry 3 reaches the vicinity of the short edge large plate positioning cylinder group 5, the plate material is placed down by the lifting cylinder 103, the plate material is released by the grabbing suction cup, then the gantry 3 is moved to the center of the plate material, the long edge pushing cylinder 7 and the short edge pushing cylinder 8 are controlled respectively to push the plate material in turn, then the long edge pushing cylinder 7 and the short edge pushing cylinder 8 are controlled to push the plate material at the same time, so as to guarantee that the plate material is closely attached to the long edge positioning cylinder group 4 and the short edge large plate positioning cylinder group 5, and positioning is completed. When the identification component identifies that the plate material grabbed by the grabbing suction cup is a small plate material, the control system controls the cylinder column of the short edge small plate positioning cylinder group 6 to extend to the table 2, after the plate material is stably grabbed by the feeding device 1, the gantry 3 is moved, so that the gantry 3 reaches the vicinity of the short edge large plate positioning cylinder group 5, the plate material is placed down by the lifting cylinder 103, the plate material is released by the grabbing suction cup, then the gantry 3 is moved to the center of the plate material, the long edge pushing cylinder 7 and the short edge pushing cylinder 8 are controlled respectively to push the plate material in turn, then the long edge pushing cylinder 7 and the short edge pushing cylinder 8 are controlled to push the plate material at the same time, so as to guarantee that the plate material is closely attached to the long edge positioning cylinder group 4 and the short edge small plate positioning cylinder group 6, and positioning is completed. Therefore, the plate material switching of the cutting machine can be automatically realized.

[0104] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the present application.
