Fully automatic punching and binding equipment and method thereof

technical field

The invention relates to a punching and binding device and a method thereof, in particular to a fully automatic punching and binding device and a method thereof.

Background technique

With the prosperity of the market economy, the efficiency of commercial activities is getting higher and higher, and the business volume undertaken by the financial industry, which is the main stage of economic life and an important hub of social life, has also increased unprecedentedly. The use of various bills continues to rise, and bill binding has been transformed from an auxiliary process into an important step. The efficiency of this task will directly affect the efficiency of financial activities. Similarly, the quality of this work will also affect the quality of financial activities. Quality, which further affects the credibility of financial institutions in the market. Therefore, the traditional manual binding method is no longer suitable for this high-quality and efficient work requirement and should be eliminated. At the same time, modern people's awareness of environmental protection and health is getting higher and higher. The traditional paper punching (drilling, punching) method produces a lot of flying debris, which is very harmful to the air and human body. In daily production and life, punching and binding work can be seen everywhere. Such equipment is also various and varied, but the combined punching and binding machine that combines binding and punching functions has not been published so far. .

The status quo of several common punching equipment on the market is: 1. Desk calendar punching machine: desk calendar punching is generally punching special-shaped holes. Make different punches and form them on a hydraulic punching machine. 2. Stamp punching machine: Stamps are called "the business card of the country", which not only requires exquisite printing, but also has high requirements for the shape and position accuracy of the perforations. At present, the stamp punching equipment used in our country is the most advanced numerical control comb type stamp punching machine, which is completed by PLC control on the basis of mechanical punching machines. 3. Battery slot punching machine: Many automotive battery shell products produced in my country require a connection hole to be processed on the separator between each slot to connect the pole plate. Since the hole is inside the groove and is limited by the width of the groove, it needs to be processed by a special method. For this reason, a hydraulic punching machine that realizes punching through hydraulic transmission has emerged as the times require. In order to adapt to punching batteries of various specifications, in addition to the hydraulic system, the punching machine also needs to consider the design of the mechanical adjustment mechanism including the up and down, left and right, front and rear directions, and practical issues such as sealing. 4. Laser drilling machine: Laser technology is a high-tech developed in the 1960s. It is widely used in electronics, mechanical processing and manufacturing, light industry, transportation, communication, energy and military industries. It has developed particularly rapidly in recent years. All advanced countries in the world attach great importance to the development of laser technology in order to promote the development of science and technology and production. my country's laser technology has made great progress through the "Sixth Five-Year Plan" and "Seventh Five-Year Plan", but there is still a big gap compared with the advanced industrial countries in the world. At present, about 50% of the domestic laser market is occupied by foreign laser manufacturers; especially about 80% of laser drilling equipment is imported. In order to change this situation as soon as possible and meet the needs of my country's economic construction, we must firmly grasp the development and application of laser technology and the construction of the laser processing industry as the central link, and provide complete sets of laser processing equipment (including laser Laser processing equipment such as punching machines) basically meet the needs of the domestic market. At the same time, we should also actively introduce foreign advanced technology, the laser products that have been introduced, and develop intelligent laser drilling machines. The main indicators of this intelligent laser drilling machine are: processing materials: Al ₂ O ₃ ceramics, stainless steel, and expand to other materials; processing material thickness: 5mm; processing aperture: Φ0.05～1mm; processing speed: 50 holes /min; processing the largest workpiece: 100 × 100mm; stability, reliability: under the condition of meeting the above technical indicators, work continuously for 4 hours. At present, the world laser market is developing rapidly. According to relevant foreign reports, in the laser product market, metal cutting, welding, surface treatment, drilling, and marking have the fastest growth. Among them, laser cutting accounts for about 70% of laser processing, and laser drilling accounts for about 15%. 5. There are also cigarette paper punching machines, lawn punching machines, edible fungus wood punching machines, etc. Their working principles are similar to those of the above-mentioned punching machines, and will not be repeated here.

my country's binding machine market is also in line with the international market. World-renowned office supplies manufacturers such as French treasure, Puma, Yali, Meilian, Epico, Libao and other companies have entered the Chinese market one after another. Various types of binding machines produced in mainland my country, Hong Kong Special Administrative Region, and Taiwan Province are continuously introduced and displayed in the Chinese market, which opens the eyes of users and appreciates various trendy products. At present, an electronically operated hot-melt binding machine on the market belongs to a non-porous binding machine. It melts the hot glue on the ridge of the "thermal energy envelope" through an electronic or hot plate, and cools down after fusing documents or other files and materials. Locked into a book. Apron + hot melt, iron ring + apron 2-in-1 binding machine combines the two functions of apron, hot-melt "two-in-one" binding machine and hot-melt binding machine into one model.

Due to the urgent need for combined punching and binding equipment in work and life, dozens of manufacturers in China have produced combined automatic punching and binding equipment. In the prior art, no flying debris and environmentally friendly automatic punching and binding machines are basically Semi-automatic equipment, usually, after the punching is automatically completed, it needs manual operation to put the plastic tube into the hole, press the upper heating mold to heat the plastic tube to complete the binding, and its disadvantages are:

1. The failure rate is high, the trouble-free working time is short, and the failures are diverse;

2. The service life is low, and the repair rate is high during the warranty period;

3. The performance is not high, when the punching thickness exceeds 50mm, the punching quality will drop significantly;

4. Severe wear and tear, rapid failure of parts;

5. The automation of the whole process of punching and binding cannot be realized.

To sum up, the overall performance of the existing automatic punching and binding machines is not high, and the equipment is still at a semi-automatic level. Hole binding machine.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, Figure 3-1 and Figure 3-2, the punching and binding machines in the prior art generally use a gear-rack transmission system during the punching process. Under the condition of punching depth (that is, binding thickness), the failure rate of the transmission parts of the feed system is high. The performance is: the meshing gap of the open rack and pinion transmission is unstable, and the teeth on the gear or rack are deformed or broken. Its reason is: when the binding paper intensity is higher, along with hollow drill bit 7 drills deeply, the resistance of paper to drill bit becomes larger, when shredded paper scraps are discharged from hollow drill bit 7, also further increased the drill bit. The resistance, therefore, makes the above-mentioned problems occur in the rack-and-pinion feeding system that requires high installation accuracy.

The screw transmission adopted in the present invention is composed of a spiral lifting rod 4 and a slider 5, which has good bearing capacity, low installation accuracy requirements, small quality and volume, low noise, good fine-tuning and fine-displacement, good self-locking performance, and long service life. With good stability, it is more suitable as the feed transmission system of automatic punching and binding machines. Through the actual working conditions and prototype experiments of the screw drive feeding system, it is proved that the screw drive can accurately realize the feeding of automatic drilling.

Fig. 1, Fig. 2-1 and Fig. 2-2 show the structure and working process of the punching mechanism and the self-locking sleeve pressing mechanism in the present invention:

The punching device is composed of a hollow drill bit 7 connected to the first motor 3, a self-locking sleeve pressing mechanism 8 set on the guide post 30, and a first spring 31 set on the guide post 30. The hollow drill bit The lower end of 7 is provided with a photoelectric switch, and the photoelectric switch is connected with the circuit control system 1; the self-locking sleeve pressing mechanism 8 includes a slider 5 and a pressing plate 81 sleeved on the guide post 30, and the pressing plate 81 The hole on the top is a tapered hole with a large mouth facing upwards. A cage 82 is arranged in the tapered hole, and a metal ball 83 is arranged in the cage 82. The slider 5 and the holder in the tapered hole A second spring 84 is provided between the frames 82 ; a travel switch is provided above the guide post 30 above the slider 5 , and the travel switch is connected to the circuit control system 1 .

When punching holes, the screw transmission makes the slide block 5 move downwards, and through the effect of the second spring 84, the pressing plate 81 moves downwards, and at the same time compresses the first spring 31, and the pressing plate 81 presses the bill on the workbench 29 and stops moving. The slider 5 continues to compress the first spring 31 and punch holes. After the punching is completed, the slider 5 moves upwards and returns to its original position. According to the principle of tribology, when the angle A between the pressure plate 81 and the guide post 30 is smaller than the When the friction angle of the pressing plate 81 is B, that is, A<B, the pressing plate 81 keeps self-locking under the action of the metal ball 83, and the pressing plate 81 continues to press the bill, and the active force of the second spring 84 changes from pressure to tension.

When the slider 5 returns to the original position, the travel switch is triggered, and the slider 5 stops at the original position, because the slider 5 and the spiral lifting rod 4 form a screw transmission system, as shown in Figure 3-1, the screw transmission has self-locking function, so slider 5 does not move downward. Simultaneously upper and lower electric heating molds 23 and 17 carry out the binding process.

The electric heating mold 23 moves to the top of the bill, presses the pressure plate 81 and melts the plastic tube in the bill hole, under the action of the upper heating mold 23, the metal ball 83 and the pressure plate 81 are separated instantly, and the second spring Under the action of 84 tension, two metal balls 83 move upward together with the cage 82 and return to their original positions.

After the electric heating mold 23 completes the hot-melt binding, it moves upward first, and then moves horizontally back to its original position. Since the pressing plate 81 does not have the effect of the metal ball 83, under the pressure of the first spring 31, the pressing plate 81 follows the electric heating mold. 23 move upward together and return to the original position.

Fig. 1, Fig. 4-1 to Fig. 4-8 have shown the structure and working process of upper and lower heating mold in the binding mold among the present invention:

As shown in Figure 1, the electric heating mold device adopted in the automatic punching and binding equipment of the present invention includes an upper heating mold 23 and a lower heating mold 17, and the basic structure of the upper heating mold 23 or the lower heating mold 17 is the same In order to facilitate the description of the following heating mold 17 as an example, as shown in Figure 4-1, the lower heating mold 17 includes a frame, a disc cam 12 coaxially arranged with the cylindrical cam 13, The roller mechanism 45 that the working end surface contacts, and the slider mechanism that contacts with the rotary working surface of the disc cam 12; the roller mechanism 45 is fixedly connected with the slider mechanism; the slider mechanism includes a support rod The slider 44 on the top, the spring 40 between the slider 44 and the frame on the support rod, one end of the slider 44 is provided with a guide rail 41 that is in contact with the rotary working surface of the disc cam 12, and the other end is provided with There is a die M. As shown in Fig. 4-3, another embodiment is to arrange the above-mentioned spring 40 between the guide rail 41 and the frame.

4-5 shows another technical solution of the present invention taking the lower heating mold 17 in the electric heating mold device of the automatic punching and binding machine as an example, that is, the lower heating mold 17 includes a frame 1. The disc cam 12 coaxially arranged with the cylindrical cam 13, the roller mechanism 45 contacted with the working end surface of the cylindrical cam 13, and the slider mechanism contacted with the rotary working surface of the disc cam 12; The sub mechanism 45 is slidingly connected with the slider mechanism, that is, the slider 44 is sleeved on the roller shaft of the roller mechanism 45; one end of the roller shaft is provided with a roller, and the other end is provided with a Die M; a support rod is provided between the slider 44 and the frame on the equipment, and the support rod and the slider are welded together in an intersecting positional relationship, and the support rod is located on the A spring 40 is sleeved between the slide block 44 and the frame, and a guide rail 41 is arranged on the other end of the intersecting position with the slide block 44, and the guide rail 41 is welded on the support rod, and the guide rail 41 and the The return face of the disc cam 12 is in contact. As shown in FIGS. 4-6 , another embodiment is to arrange the spring 40 in the above-mentioned FIGS. 3-3 between the guide rail 31 and the frame.

No matter which specific embodiment is adopted, the cylindrical cam 24 (or 13) and the disc cam 27 (or 12) in the structure of the upper heating mold 23 or the lower heating mold 17 in the present invention are connected in parallel. type combination; a transmission device is provided between the upper heating mold 23 and the lower heating mold 17, and the transmission device adopts a reducer structure, which may include a multi-stage reducer composed of a pulley reducer 21 and a gear reducer 16. The punching and binding equipment of the present invention requires horizontal movement and linear motion for the upper and lower heating molds in the working process, and requires a stop, so the structures of the upper and lower heating molds are the same. As we all know, although the cam mechanism in mechanical transmission can realize any trajectory, a single cam cannot satisfy the synthesis of horizontal motion and vertical motion at the same time. Group cam combination.

The motion tracks that can be realized after the combination of the two groups of cams are further described below.

After punching the hole, the hollow drill bit 7 returns to the original position, and the plastic pipe 22 in the hole is heated by the heating mold 23 and 17 in the mold device among the present invention. The lower heating mold 17 needs to move horizontally to the limit position and keep stopping. After the plastic tube 22 is cut off, the plastic tube 22 falls on the positioning pin of the lower heating mold 17 by its gravity. The position of the plastic tube 22 that comes, and send the plastic tube 22 to the ticket hole. After the lower heating mold 17 moves horizontally to the original position, it immediately moves upward to the limit position and keeps stopping. After the plastic tube is melted, the lower heating The mold 17 moves vertically downwards to the original position to complete a cycle, and its trajectory is shown in Figure 4-7, that is, the lower heating mold 17 first stops at point A from B→A, and then from A→B→C, Stop at point C, then C→B, so far complete a cycle. At the same time, the upper heating mold 23 needs vertical movement to melt the plastic pipe in the hole. Since the upper heating mold 23 cannot be on the same vertical plane as the slide block 5 with the hollow drill bit 7, a horizontal movement is required. Therefore, the trajectory of the upper heating mold 23 is shown in Figure 4-8, that is: point E is the original position, first from E→D→F, stop heating at point F, and then return to the original position from F→D→E complete the cycle. It can be seen from the above-mentioned motion traces of the upper and lower heating molds that the functions required by the two heating molds are the same: they can realize horizontal movement and vertical movement at the same time, and can stop.

According to the basic function of motion conversion, the mechanisms that can realize continuous rotation→double-sided stop linear movement include: moving follower cam mechanism, using connecting rod track to realize stop motion mechanism, incomplete rack and pinion reciprocating movement intermittent mechanism, incomplete The gear moves the guide rod intermittent mechanism. Since the track of the link mechanism is a curve, the incomplete gear mechanism has disadvantages such as greater impact and noise when it starts to engage and disengage, so the present invention adopts a cam mechanism.

The movement cycles of the lower heating mold and the upper heating mold in the present invention will be described in more detail below with reference to FIG. 1 and FIGS. 4-4 .

Lower heating mold 17: input at constant angular velocity w1, with 360° as a cycle, within 0～Φ3, as shown in Figure 1-1, the rotation of the disc cam 12 occurs on the arc surface corresponding to the small radius r1, the guide rail 31 keep vertical stop, promptly the M point of lower heating mold 17 keeps vertical stop. At 0～Φ1 (Φ1<Φ2<Φ3<360°) the cylindrical cam 13 realizes the horizontal movement, and under the action of the spring 40, the roller shaft in the roller mechanism 35 moves to the left limit position, that is, the M of the lower heating mold 17 The point moves from the right limit position to the left limit position; at Φ1～Φ2, the cylindrical cam 13 makes the M point of the heating mold 17 stay horizontal; at Φ2～Φ3, because the cylindrical cam 13 rotates an angle, the spring 40 is compressed, at this time , the M point of the lower heating mold 17 moves horizontally from the left limit position to the right limit position. The lower heating mold 17 completes the process from B→A→B as shown in Figure 5-1. At Φ3～360°, the cylindrical cam 13 acts to make the M point keep horizontal and stop at the right limit. In Φ3～Φ4 (Φ3<Φ4<Φ5<Φ6<360°), under the action of disc cam 12, point M moves to the upper limit position; in Φ4～Φ5, disc cam 12 keeps point M at the upper limit Stop vertically to complete the process of heating the hot-melt plastic pipe of the mold; at Φ5～Φ6, the disc cam 12 makes the M point move from the upper limit to the lower limit (ie original position), Φ6～360°, the M point keeps stopping and stops vertically. The lower heating mold 17 completes the process from B→C→B as shown in Figure 5-1.

Upper heating mold 23: as shown in Fig. 1-2, similarly, the disc cam 27 realizes vertical movement, and cylindrical cam 24 realizes horizontal movement. In w1 uniform angular velocity input, 360° as a cycle, within 0～Φ2, as shown in Figure 1-2, due to the action of cylindrical cam 24 and disc cam 27, the K point on the upper heating mold 23 remains in place Pause; at Φ2～Φ3 (Φ2<Φ3<Φ4<Φ5<Φ6<Φ7<360°), due to the action of the cylindrical cam 24, the horizontal movement of point K moves from the original position (left limit) to the right limit, and the disc cam 27 Still keep the K point to stop vertically; at Φ3～Φ4, the disc cam 27 makes the K point move vertically, that is, the K point moves from the upper limit to the lower limit, and the cylindrical cam 24 keeps the K point at a horizontal stop; at Φ4～Φ5, Cylindrical cam 24 and disc cam 27 keep point K horizontal and vertical to stop, and complete the process of heating the mold 23 to melt the plastic pipe; at Φ5～Φ6, disc cam 27 makes K point move from the lower limit position to the upper limit position , Cylindrical cam 24 keeps K point to stay horizontally; at Φ6～Φ7, disc cam 27 keeps K point to stay vertically, and cylindrical cam 24 makes K point move from right limit to left limit (original position). The upper heating mold 23 completes the process from E→D→F→D→E as shown in Figure 5-2.

In the present invention, the upper electric heating mold 23 and the lower electric heating mold 17 can realize horizontal movement and vertical movement respectively, so that the upper electric heating mold 23 can avoid the punching device during the movement process, and the lower electric heating mold 17 can automatically Select the plastic pipe, and then complete the hot-melt process with the electric heating mold 23.

The structure and characteristics of braking device in the present invention:

As shown in Figure 6-1, in the automatic punching and binding equipment of the present invention, the camshafts of the upper and lower heating mold mechanisms are respectively provided with braking devices 25 and 14, including coils, armatures 62, racks, springs 63, The first block 64 and the second block 65 located on the outer surface of the camshaft; the frame is connected with one end of the armature 62 and the first block 64 and the second block 65 respectively, and the other end of the spring 63 It is connected with the armature 62, one end of the armature 62 is connected with the frame, and the two ends of the moving link 66 are respectively connected with the supports of the first brake block 64 and the second brake block 65, and the second brake block The support of 65 is provided with rotating fulcrum. According to general mechanical design principles, dozens of specific embodiments can be extended under the inspiration of the structure of the above-mentioned braking device. Figure 6-2 to Figure 6-7 show six of them, and the rest Examples will not be repeated here.

The braking device has the advantages of simple structure, fast braking and low cost. During the braking process of the braking device, due to the inertia of the moving axis, the actual stop rotation angle has a slight angle deviation from the theoretical stop rotation angle, because it is not necessary to achieve instantaneous braking in the process of bill punching and binding , so even if there is a deviation of the above-mentioned small angle, it will not affect the quality of punching and binding. Therefore, the processing of the braking device does not require very high precision, thereby greatly reducing the production cost of the product.

The working process of the above-mentioned braking device is: when the coil is energized, a magnetic force is generated to make the armature 62 move to the right or left, and compress or stretch the spring 63 to drive the moving connecting rod 66 to move, so that the first brake block 64, the second The second brake block 65 holds the center motion shaft 67 tightly to generate braking. When the coil is not energized, the electromagnetic force disappears, and the spring 63 returns to its original length under the action of its own elastic force, so that the armature 62 and the connecting rod 66 move left or right, and the first brake block 64 and the second brake block 65 loosen the middle The motion shaft 67, the motion shaft 67 resumes motion.

The structure and working process of workbench among the present invention:

As shown in Figure 1, Figure 5-1 and Figure 5-2, the workbench includes a fixed frame 54 and a floating frame 52, the fixed frame 54 is provided with a plurality of grooves, and the floating frame 52 is provided below There are a plurality of pillars corresponding to the number and position of the plurality of grooves one by one, and each pillar is sleeved with a spring 53 and then inserted into the corresponding groove; Belt pulley 19, described belt pulley 19 is driven by stepper motor 10, and the upper surface of described floating frame 52 is provided with the belt that cooperates with described belt pulley 19, thus constituted belt workbench B, on described belt workbench B There are 20 mechanisms with vernier. Wherein, the belt workbench B is higher than the workbench A on the fixed frame 54 under the effect of the spring 53 .

The working process of the above-mentioned workbench is: after the ticket to be bound is placed on the belt workbench B, because the belt workbench B is driven by the pulley 19, the bills on it also move horizontally to the right thereupon, because the belt workbench B It is higher than workbench A on the fixed frame 54, and the center of gravity of the bill is on the surface of the belt workbench B. The bill will not contact the working surface of the stationary workbench A during the movement, so the bill can still be placed neatly on the belt. On the B side of the workbench, there will be no chaos.

After the stepper motor 10 stops working, the belt workbench B stops moving horizontally thereupon. At this moment, the equipment can carry out punching and binding. Compress spring 53 down, after floating frame 52 is in rigid contact with equipment rack, belt workbench B stops moving downwards, and belt workbench B is designed to be at the same level with workbench A surface simultaneously, is convenient to punching and binding.

After finishing above-mentioned punching and binding process, pressing plate 81 returns to the original position, and belt table B holds bill upwards to float under the effect of spring 53, has finished the work cycle of punching and binding of a hole on the bill so far. Subsequently, the bill moves with the belt table B to punch and bind the next hole. By analogy, when the task of punching and binding the entire bill is completed, the belt working surface B transports the bill to the far right, so that it is separated from the automatic punching and binding equipment, thereby completing the entire operation of punching and binding the bill.

In the equipment of the present invention, a bevel gear reducer 11 is arranged between the output shaft of the feed motor 18 and the spiral lifting rod 4, so as to achieve both speed change and direction change transmission.

The automatic punching and binding method of the present invention comprises the following steps:

1. Determine the number of holes and the position of each hole when binding bills: first, put the bills neatly on the surface B of the workbench made of belts, move the cursor 20 in the device to the position where the holes need to be punched, and one cursor corresponds to The location of a hole. Then, start the power supply, the stepper motor 10 rotates, and drives the belt workbench B to move slowly to the right, and the cursor 20 and the bill file move with the workbench B. There is a photoelectric switch directly below the perforating hollow drill bit 7. When the cursor 20 moves to the photoelectric switch, the photoelectric switch is triggered, and the circuit control system 1 receives a signal.

2. Punching:

After the circuit control system 1 receives the signal, the stepping motor 10 stops, the bill stops at the position where the punching hole is to be set, the feed motor 18 and the first motor 3 are started, and the screw drive system drives the slide block 5 on the frame downward. movement, the pressing plate 81 in the self-locking sleeve pressing mechanism 8 moves downward together, thereby pressing and fixing the bill; after the first motor 3 drives the hollow drill bit 7 to complete the punching, it triggers the contact sensor arranged on the workbench. The position of the trigger is directly below the hollow drill bit 7. The trigger will be triggered when the hollow drill bit 7 breaks through the bill, so that the feed motor 18 is reversed. Trigger the travel switch that is arranged on the frame when block 5 gets back to the original position, at this moment, clutch 28 is disconnected state, and helical lifting lever 4 stops driving, and sliding fast 5 also stops moving upwards, and in self-locking sleeve compression mechanism 8, The pressing plate 81 continues to compress the document;

3. Pipe cutting: After the slider 5 triggers the travel switch, the circuit control system 1 makes the feed motor 18 rotate forward, the third clutch 28 is disconnected, the first clutch 15 and the second clutch 26 are connected; the upper and lower heating molds 23 And 17 motions, lower heating mold 17 moves horizontally to the right limit position and stops, and after plastic pipe 22 is cut off, this plastic pipe falls on the positioning pin of lower heating mold 17.

4. Binding: the lower heating mold transports the plastic tube 22 to the hole of the bill, the upper and lower heating molds 23 and 17 heat the plastic tubes to complete the binding, and the upper and lower heating molds 23 and 17 return to the original position to trigger the travel switch and self-lock The cover pressing mechanism 8 releases the bill under the action of the upper heating mold 23, and returns to the top under the action of the spring 31; at this time, the lower heating mold 17 triggers the signal, the first clutch 15 and the second clutch 26 are disconnected, and the first The braking device 14 and the second braking device 25 start, the input shafts of the upper and lower heating molds 23 and 17 are braked, and the upper and lower heating molds 23 and 17 complete a cycle of 360°; meanwhile, the stepper motor 10 starts.

The above steps 1 to 4 complete the punching and binding of a hole on the bill, and so on until the punching and binding of the bill is completed. During the punching process of bills, the paper dust is first stored in the dust collector 6 above the hollow drill bit 7, and as the paper dust increases, it will be discharged through the dust discharge pipe 9, which avoids the flying phenomenon of paper dust.
