Description

Technical Field

[0001] The invention belongs to the technical field of woodworking equipment and relates to a hinge machine. Background Art

[0002] In the furniture manufacturing industry, the doors of various cabinets are mostly connected to the cabinet body through hinges or hinges. A row of holes for installing hinges must be drilled on the sides of these cabinet doors. Depending on the size of the door and the number of hinges used, multiple holes are generally required. At present, the processing of cabinet door hinge holes is generally processed by hinge machines.

[0003] For example, Chinese patent [application number: 201510056963.8] discloses a hinge machine, which includes a frame and a drilling unit arranged side by side on the transverse guide shaft of the frame and capable of moving on the transverse guide shaft; the drilling unit includes a first drilling unit, a second drilling unit, a third drilling unit and a fourth drilling unit; the frame is provided with a first transverse screw for driving the first drilling unit to move on the transverse guide shaft; the frame is provided with a second transverse screw for driving the second drilling unit to move on the transverse guide shaft; the frame is provided with a third transverse screw for driving the third drilling unit to move on the transverse guide shaft; the frame is provided with a fourth transverse screw for driving the fourth drilling unit to move on the transverse guide shaft. The drilling unit in the invention drills hinge holes from bottom to top, so that wood chips can be sucked away from the dust exhaust sleeve at the back, reducing the pollution of the wood chips working environment, and multiple lock holes can be drilled for the door panel at the same time, and the drilling position can be freely adjusted by adjusting the slide.

[0004] However, the feeding operations of the above-mentioned hinge machine, such as loading and unloading of wood, need to be performed manually, which results in low processing efficiency of the hinge machine and does not meet the production requirements of modern automated processing; for this reason, for example, Chinese patent [application number 201710719511.2] discloses a CNC device for processing hinge holes of panel-type custom furniture, including a conveying device, a drilling mechanism, an X-direction moving mechanism, a Y-direction moving mechanism and a Z-direction moving mechanism; the Y-direction moving mechanism is installed on the X-direction moving mechanism, the Z-direction moving mechanism is installed on the Y-direction moving mechanism, and the drilling mechanism is installed on the Z-direction moving mechanism; the conveying device The plate conveying mechanism includes a plate conveying mechanism, a push plate mechanism and a plate limiting mechanism. The push plate mechanism is arranged on the plate conveying mechanism. The push plate mechanism includes a push plate, a push plate driving mechanism and a plate pressing component. The push plate driving mechanism is connected to the push plate and is used to push the plate to the drilling mechanism. The plate pressing component is installed on the push plate. The plate conveying mechanism includes a fixed platform, a conveyor belt, a conveyor belt bracket and a lifting cylinder. The fixed platform is provided with a plurality of belt grooves. The conveyor belts are arranged in a plurality of belt grooves respectively. Each conveyor belt is installed on the conveyor belt bracket. The lifting cylinder is connected to the conveyor belt bracket and is used to lift the conveyor belt out or retract it into the belt groove. The invention performs CNC drilling processing on hinge holes of customized furniture, realizes the automation of plate feeding during hinge hole processing, and meets the needs of large-scale production of customized furniture orders.

[0005] However, a specific analysis of its feeding process shows that the above-mentioned CNC equipment still has the following defects: during the loading process of the plate, the lifting cylinder controls the conveyor belt to rise. When the plate is transported by the conveyor belt to the top of the fixed platform, the positioning of the plate in the length direction is achieved by the limit column located at one end of the conveyor belt. After the positioning in the length direction is completed, in order to allow the plate to be supported by the fixed platform, the conveyor belt needs to be controlled by the lifting cylinder to descend into the belt groove of the fixed platform, and then pushed to the processing area by the push plate for punching; when the plate is processed, the conveyor belt needs to be controlled by the lifting cylinder to rise to the fixed platform. The plate will be lifted up by the conveyor belt and then sent out by the conveyor belt to realize unloading; that is to say, in the feeding process of the above-mentioned plates, the conveyor belt needs to rise or fall repeatedly, and each plate punching process needs to wait for the conveyor belt to land, and the next plate can only enter the fixed platform after the punched plate is completely conveyed out, which results in a long waiting time for feeding, especially when the length of the processed plate is short, the plate needs to be driven by the conveyor belt for a distance before the punching process can be carried out, so the waiting time is even longer, resulting in very limited improvement in the production efficiency of the hinge machine. Summary of the invention

[0006] The purpose of the present invention is to solve the above problems in the prior art and to propose a hinge machine. The technical problem solved by the present invention is how to improve production efficiency.

[0007] The object of the present invention can be achieved through the following technical solutions: a hinge machine, comprising a frame and a plate-shaped workbench fixed on the frame, characterized in that a roller conveyor line is provided on the frame, the roller conveyor line comprises a plurality of rollers arranged at intervals along the length direction of the workbench and capable of rotating along the length direction of the workbench, the top height of each roller is consistent with the height of the upper surface of the workbench or slightly higher than the upper surface of the workbench, a processing gap for a drill bit to pass through is formed between the inner side of the roller conveyor line and the workbench, and pushing devices capable of pushing the plate into and out of the processing gap are provided on both sides of the processing gap.

[0008] The hinge machine improves the feeding structure, directly shortens the processing time of the hinge machine for the plate, thereby better improving the production efficiency of the hinge machine; specifically, the hinge machine designs a roller conveyor line on one side of the workbench, which is composed of a row of rollers arranged at intervals along the length direction of the workbench and can rotate along the length direction of the workbench. The top height of all rollers is consistent with the height of the workbench. Since the rollers themselves have a certain elasticity, they can also be slightly higher than the upper surface of the workbench, about less than 0.5mm higher. A processing space for the drill to pass through is formed between the roller conveyor line and the workbench. The plate is pushed out of the processing gap by the pusher device on both sides of the processing gap. When the plate needs to be loaded, the plate is transported to the position by the roller conveyor line, and then pushed to the top of the processing gap by the pusher device on one side. After the plate is in position, it is pressed by the clamping device of the hinge machine and then drilled. After the processing is completed, when the plate is discharged, the pusher device on the other side pushes the plate out of the processing gap, so that the whole plate contacts the roller conveyor line. At this time, the plate is transported out by the roller conveyor line to complete the discharge. From the analysis of the feeding process of the hinge machine, it can be seen that since the position of the roller conveyor line and its height with the workbench are basically consistent and form The design of the processing gap makes the roller conveyor line not only play the role of conveying the plate, but also play the role of supporting the plate, that is, the roller conveyor line composed of several rollers actually plays the role of supporting the plate during processing, that is, in the whole process of plate pressing processing, because the roller conveyor line has both the functions of conveying and supporting, so that the roller conveyor line itself does not need to be moved to avoid during the processing, and there is no need to delay the feeding time and affect the smoothness of the whole feeding operation. In this way, in the process of plate feeding, the hinge machine only needs to carry out the roller conveyor line feeding, the pushing device pushing, processing operation, the pushing device pushing out, and the roller conveyor line conveying out to complete the whole feeding operation. The whole action is continuous, and there is no extra time delay in the middle, thereby better improving the production efficiency of the hinge machine; at the same time, the roller conveyor line and the workbench form a processing gap. The design makes the processing area of ​​the plate as close to the roller conveyor line as possible, which is the in-and-out conveying component, thereby saving the travel of the pushing device feeding and the pushing device discharging, further shortening the time required for the feeding operation, and further improving the production efficiency of the hinge machine.

[0009] In the above-mentioned hinge machine, a strip-shaped auxiliary plate is provided on the inner side of the roller conveyor line, which is arranged along the length direction of the workbench and fixed to the frame. The width of the roller conveyor line is greater than the width of the auxiliary plate. The upper surface of the auxiliary plate is flush with the upper surface of the workbench, and the processing gap is formed between the auxiliary plate and the workbench. Through the cooperation of the auxiliary plate and the roller conveyor line, when the plate is processed, it is partially supported by the auxiliary plate and partially supported by the roller conveyor line. In addition, since the auxiliary plate is closer to the processing gap, the support of the plate in the processing area where the processing gap is located can be more reliable, thereby providing a strong guarantee for the roller conveyor line itself to be able to serve as a support platform to provide reliable support for the plate. In addition, during the entire plate pressing process, the roller conveyor line itself does not need to be evasive and moved, and there is no need to delay the feeding time, which is beneficial to improving the production efficiency of the hinge machine. At the same time, since the width of the roller conveyor line is greater than the width of the auxiliary plate, most of the support is provided by the roller conveyor line when the plate is processed. That is to say, only a small part of the plate is located above the processing gap and the auxiliary plate. In this way, after the processing is completed, the pushing device only needs to push the plate a short distance so that the roller conveyor line can drive the plate out, thereby saving the outflow time and improving the production efficiency of the hinge machine.

[0010] In the above hinge machine, the auxiliary plate has a plurality of convex teeth arranged at intervals in the transverse direction on one side close to the roller, and a clearance opening is formed between two adjacent convex teeth. The roller corresponds to the clearance opening one by one, and one end of the roller is located in the corresponding clearance opening. Through the design of the convex teeth, the space between the auxiliary plate and the roller is fully utilized without affecting the installation of the roller, so as to better assist the roller conveyor line to provide reliable support for the plate, and the above design does not increase the distance that the auxiliary plate extends inward relative to the roller conveyor line, so that the pushing stroke of the pushing device will not be increased, which is conducive to improving the production efficiency of the hinge machine.

[0011] In the above-mentioned hinge machine, the frame is provided with at least two limit backrests which are arranged at intervals along the length direction of the workbench and can be moved to the top of the roller conveyor line to block the conveyance of the plates. Through the design of the above limit backrests, short plates are limited by the front limit backrest, and long plates are limited by the rear limit backrest. In other words, the position of the plates does not need to be determined by the start and stop control of the roller conveyor line, so that the roller conveyor line can work without stopping, thereby improving production efficiency; at the same time, when the shorter plates enter the roller conveyor line, they can be limited by the front limit backrest, and are blocked by the limit backrest, so that the roller conveyor line can work without stopping, and then the pushing device works to push the materials, and then the pressing process is carried out. At this time, the roller slips relative to the rubber sleeve mounted outside the roller. After the processing is completed, it is released. By opening the limit backrest, the processed plates can continue to be conveyed backwards. From the above analysis, it can be seen that short plates can be processed at a position close to the feeding end of the roller conveyor line. After processing, when it is conveyed backwards, the next plate to be processed does not need to wait for the previous plate to completely leave the roller conveyor line and can enter the roller conveyor line in advance, thus reducing the waiting time for the next plate and improving production efficiency; and the roller conveyor line can continue to operate, which is also conducive to improving production efficiency; in addition, through the spacing design of the above-mentioned at least two limit backrests, at least two plates can be punched at the same time, which is also conducive to improving production efficiency.

[0012] In the above hinge machine, a telescopic cylinder is provided above, below or to the side of the roller conveyor line, the telescopic cylinder is fixed to the frame, and the limit backer is driven by the telescopic cylinder. Through the above design, the limit backer can be moved above the roller conveyor line to block and limit the plate conveyance.

[0013] As another solution, in the hinge machine mentioned above, the frame is provided with at least one limit backer which is adjustable in position in the length direction of the workbench and can be moved above the roller conveyor line to block the conveyance of the plate. The frame is slidably connected with a mobile platform which can be moved along the length direction of the workbench, and a telescopic cylinder is fixed on the mobile platform, and the limit backer is driven by the telescopic cylinder. Through the limit backer designed above, the position of the limit backer can be adjusted according to the length limit requirement of the plate, and the position of the plate does not need to be determined by the start and stop control of the roller conveyor line, so that the roller conveyor line can work without stopping, and the waiting time for processing short plates is saved, thereby improving production efficiency.

[0014] In the above-mentioned hinge machine, the pushing device includes an ejection device located on the inner side of the processing gap and a propulsion device located on the outer side of the processing gap, the ejection device includes a reference backer fixed on the workbench and arranged in the transverse direction, the reference backer is provided with a plurality of guide slots spaced in the transverse direction, each guide slot is provided with a corresponding push block, each push block can move in the longitudinal direction under the drive of the corresponding driving member 1; the propulsion device includes at least two push bars arranged above the roller conveyor line and arranged in sequence along the length direction of the workbench, the frame is provided with a driving member 2 corresponding to the push bars one by one, the push bars are slidably connected to the frame and can move in the longitudinal direction toward the workbench under the drive of the corresponding driving member 2. The above-mentioned driving member 1 is an air cylinder, an oil cylinder or a screw motor. The driving member 2 is a servo motor, which is driven by a servo motor in conjunction with a belt; the driving member 2 can also be an air cylinder or an oil cylinder or a screw motor. When short plates need to be processed, the push strips in the above push device are designed to be segmented and independent, so that the next short plate enters the roller conveyor line. When the previous short plate is still left on the roller conveyor line, the pushing action of the next plate will not affect the conveying of the previous plate, thereby ensuring that the production efficiency can be improved. In addition, as another solution, the above push device includes at least two sections of moving bars arranged horizontally on the workbench and a push cylinder fixed on the workbench and corresponding to the moving bars one by one. The moving bars are fixed on the piston rod of the push cylinder and can move longitudinally under the push of the push cylinder; the above push device and the push device can also be replaced by a manipulator.

[0015] In the above-mentioned hinge machine, a plurality of support plates corresponding to the convex teeth and arranged in the longitudinal direction are fixed on the frame, the convex teeth are fixed on the corresponding support plates, and the roller is located between two adjacent support plates. Through the design of the above support plates, the auxiliary plate structure is stable, so that the roller conveyor line can play the role of a workbench, so that during the entire plate pressing process, the roller conveyor line itself does not need to avoid movement, and there is no need to delay the feeding time, which is conducive to improving the production efficiency of the hinge machine.

[0016] In the feeding structure of the hinge machine mentioned above, a horizontal slide rail arranged in the horizontal direction is fixed on the frame below the processing gap, at least two slide plates are slidably connected to the horizontal slide rail, a vertical slide rail arranged in the vertical direction is fixed to the slide plate, at least two support plates arranged in parallel in the horizontal direction are slidably connected to the vertical slide rail, and a drilling machine is fixed on the support plate. Through the above arrangement design of the drilling machine, since at least two slide plates are slidably connected to the horizontal slide rail, that is, the spacing between the drilling machines on the two slide plates can be adjusted, so that the hinge machine can perform drilling processing on plates of different specifications; at the same time, since at least two support plates arranged in parallel in the horizontal direction are slidably connected to the vertical slide rail, that is, at least two drilling machines that can slide independently in the vertical direction are provided on one slide, so that the hinge machine can process multiple hinge holes on one or both ends of the plate at the same time; therefore, through the above design, the processing efficiency of the hinge machine is improved.

[0017] In the feeding structure of the hinge machine described above, a transmission shaft arranged in the transverse direction is rotatably connected to the frame, and a belt is provided between the outer end of each roller and the transmission shaft, one end of the belt is sleeved on the outer end of the corresponding roller, and the other end of the belt is twisted and sleeved on the transmission shaft, and the transmission shaft is driven by a driving motor. Through the above design, each roller can be directly driven by the transmission shaft, and the twisted belt design makes it difficult for each independently rotating roller to slip, so that the roller can be designed to rotate at a high speed, so that the feeding and discharging conveying speed of the roller conveyor line can be accelerated, which is beneficial to improve the processing efficiency of the hinge machine.

[0018] In the feeding structure of the above-mentioned hinge machine, roller seats corresponding to the rollers are fixed on the frame between the inner and outer ends of two adjacent support plates, and the two ends of the rollers are rotatably connected to the corresponding roller seats. Through the above roller seat design corresponding to the rollers, each roller corresponds to a set of roller seats, so that the top height of each roller can be independently corrected and adjusted to ensure that the top height of each roller is consistent with the upper surface height of the workbench, so that the roller can cooperate with the workbench to play a supporting role, and then during the entire plate pressing process, the roller conveyor line itself does not need to avoid movement, and there is no need to delay the feeding time, which is conducive to improving the processing efficiency of the hinge machine.

[0019] Compared with the prior art, the hinge machine has the following advantages: the hinge machine uses the roller conveyor line as both a conveying device and a supporting platform, and is designed with a limit backrest and a pushing device, so that the hinge machine does not stop during the intermediate conveying process, the feeding action is smooth and continuous, and the waiting time for plate feeding is short, thereby effectively improving the production efficiency of the hinge machine.
