Description

Shredder and a Traveling Vehicle loaded

In the case of companies or government offices, documents that have been used or stored are expired when they have expired.The documents that should be discarded contain personal information or confidential information of the company, which causes serious problems when they are leaked to the outside. In the light of the trend of modern society, where the awareness of protection of personal information is gradually increasing, the damage is inevitably increasing. Therefore, companies or government offices may use their own shredders to shred documents that contain personal information or company secrets, but if the amount of documents kept is huge, the shredding is limited separately. The crushing work is performed through the equipment. The developed equipment is a mobile tower vehicle equipped with a crusher.

1 is a reference diagram showing the internal structure of a tower vehicle that is a mobile crusher equipped with a crusher, Figure 2 is a structural diagram showing the structure of a conventional crusher, Figure 3 is a side cross-sectional view showing the structure of a conventional crusher.

1 to 3, a crusher mounted in a conventional mobile tower a1 is rotated while the pair of cutter units 1100 are engaged with the crushing object (here, the crushing object is paper, film, photograph, etc., which is the object of the crushing operation). It is made of a separate reducer 2000 is connected between the crushing unit 1000 to crush) and the hydraulic motor 3000 to transfer the driving force to the crushing unit 1000,

Such a conventional shredder does not include a separate configuration that can accurately measure and provide the weight of the shredding object to be shredded in the shredder for various reasons, such as to reduce the weight loaded on the mobile tower vehicle, and only the shredder is operated and operated. The amount of crushing work is calculated by multiplying the unit price by the unit's capacity according to the capacity of the crusher (or mobile tower) equipped with the hour. It is difficult to obtain the trust of the consumer, and especially in the case of developing and using a shredder that can be mounted in a small tower car based on light weight and improved work efficiency, it is simply required to calculate the cost of work (regardless of the actual workload). There is a problem that causes an unreasonable aspect of receiving a lower unit price than the unit. .

In addition, as shown in FIG. 2, the speed reducer 2000 having a diameter larger than that of the drive shaft 3100 in the drive gear 3101 of the drive shaft 3100 that transmits the rotational force generated by the hydraulic motor 3000 is shown. The first reduction gear 2001 of the connection is connected, and one rotation shaft 1101 'of the rotation shaft 1101 of the pair of cutters 1100 is connected to the central shaft 2100 of the reducer 2000 again, At the side of the one rotation shaft 1101 ′, a rotation shaft gear 1102 ″ of the other rotation shaft 1101 ″ among the rotation shafts 1101 of the pair of cutter units 1100 is the central axis of the reducer 2000. The second reduction gear 2101 formed in the 2100 meshes with and rotates. Accordingly, as the driving shaft 3100 of the hydraulic motor 3000 rotates, its rotational force is the central shaft 2100 of the reducer 2000, one rotation shaft 1101 ′ of the pair of cutter units 1100, and the other. It is transmitted to the rotation shaft 1101 ″ in order so that the pair of cutter portions 1100 rotate to crush the crushed object.

However, since the structure of the conventional crusher as described above further includes a separate reducer 2000 between the crusher 1000 and the hydraulic motor 3000, the entire crusher may be damaged due to the weight of the reducer 2000. There is a problem that the weight is increased (about 4000kg) as well as occupy a lot of space to be mounted due to the increase in volume due to the reducer (2000).

In addition, by using the rotational force of the hydraulic motor 3000 in the end of the structure that rotates all of the rotary shaft 1101 of the cutter portion 1100, of course, in the drive gear 3101 of the hydraulic motor 3000 Complex structure passing through the first reduction gear 2001 of the reducer 2000 and the second reduction gear 2101 of the reduction gear center shaft 2100 through the rotating shaft gear 1102 '' of the other rotating shaft 1101 '' Since the loss of the rotational force transmitted due to the meshing rotation of the spur gears is large, the hydraulic motor 3000 has to exert a lot of force, so the size and weight of the hydraulic motor 3000 itself must also be large. There is. In addition, as the efficiency of the hydraulic motor 3000 decreases as described above, the heat generated in the hydraulic motor 3000 also increases, and therefore, a larger amount of fluid is required to cool the generated heat. There is also a problem that the size and weight of the fluid tank for storing the must also be large.

That is, the conventional shredder is large in weight and volume of the reducer, the hydraulic motor, and the fluid tank due to its structural inefficiency, which ultimately limits the weight and overall volume of the shredder (which usually occupies about 4 tons) and volume. Therefore, considering the mobility and economical efficiency of the mobile tower a1, there is a limit to the size of the processing capacity, which is the most necessary requirement, while being able to be miniaturized (ie, the weight of the entire crushing equipment mounted on the tower). Only about 4 tons of cars can be mounted to mount them, so only 8 tons of cars are available.

In addition, the chip discharge portion 5000 used to move the chip discharged from the conventional shredder (here, chip means a small piece after the shredding object is shredded) to the storage or the like, the hydraulic cylinder as shown in FIG. Since the pressure plate 5200 is used to repeat the forward (① direction) and backward (② direction) movements using the 5100, the hydraulic cylinder 5100 does not operate continuously in only one direction but intermittently. There is a problem that the operation is repeated to move forward and backward so that noise and vibration occurs every time the direction of movement changes. In addition, since the flow direction of the fluid must be continuously changed to repeat the forward and backward movements intermittently, the heat generation of the fluid is increased, so a larger amount of fluid is required to cool the generated heat, and thus the fluid is stored. The size and weight of the fluid tank also have to be large, which causes a limitation in increasing the weight of the crusher itself and miniaturization of the mobile tower.

The present invention has been made to solve the above problems,

An object of the present invention further includes a weighing unit for accurately checking and managing the weight of the shredding object to be shredded, so that the shredder can be accurately settled and provided for the shredding cost, thereby ensuring the trust of the consumer.

Another object of the present invention is to be mounted in a narrow space by reducing the volume of the crushing unit and the hydraulic motor is connected to each other so that a pair of hydraulic motors directly connected to the rotary shaft of the pair of cutter portions are opposed to each other. It is to provide a crusher and a mobile tower equipped with the same.

It is a reference figure which shows the internal structure of a small tower car.

4 to 9, a crusher according to an embodiment of the present invention is a crushing unit 10 for crushing the crushed object while rotating a pair of cutter unit 110, the driving force to the crushing unit 10 The hydraulic motor 30 for transmitting the weight, the chip discharge part 50 for discharging the chip crushed by the shredding part 10 to the outside, and the weight to check the weight of the shredding object to be subjected to the shredding operation in advance It characterized in that it comprises a measuring unit (70). For reference, the shredder according to the present invention is used to be mounted on the mobile tower, the mobile tower car equipped with a shredder designed to perform the shredding operation by moving to the place where the shredding object is located, the consumer directly in the place where the shredding operation is performed It is important to accurately present the amount of crushed objects that have been crushed to ensure the consumer's confidence in the cost problem, and to reduce the processing capacity while minimizing the capacity in consideration of mobility and economic efficiency. As a part of realization, the shredder was invented.

The shredding unit 10 is configured to crush the shredding object while rotating by engaging a pair of cutter units 110 fixed to the shelf 92. As illustrated in FIG. 4, the user inserts the shredding object into the hopper 91. In the case of inputting into the hopper 91, the crushed object introduced into the hopper 91 is dropped onto the crushing unit 10, and is engaged by the pair of cutter units 110 to rotate between the pair of cutter units 110. It will be broken.

The cutter unit 110 is formed when a plurality of cutter blades are formed surrounding the rotating shaft 111 so that a pair of neighboring cutter units 110 rotate while being rotated in opposite directions, respectively, to each cutter unit 110. The plurality of cutter blades formed are also engaged with each other to crush the object to be dropped from the top while rotating. The configuration of transmitting a driving force to rotate the pair of cutter unit 110 is a hydraulic motor 30, in the present invention, the hydraulic motor 30 to the structure for transmitting the driving force to the cutter unit 110 There are technical features.

The hydraulic motor 30 is fixed to the shelf 92 to transfer the driving force to the crushing unit 10, in the present invention, the hydraulic motor 30 is the rotary shaft of the pair of cutter unit 110 ( 111, respectively, directly connected to the driving force, thereby reducing the overall weight of the shredder can be miniaturized (as shown in Figure 9) is mounted on the small tower (a2) can be improved mobility and usability It is done.

As described above (refer to FIGS. 1 to 3), the hydraulic motor 3000 used in the conventional crusher connects a separate reducer 2000 to transmit a driving force to the crushing unit 1000 crushing the crushing object. , Of course, the structure is larger than the drive shaft 3100 to the drive gear 3101 of the drive shaft 3100 for transmitting the rotational force generated in the hydraulic motor 3000 as described above with reference to FIG. The first reduction gear 2001 of the reducer 2000 having a diameter is connected, and one rotation shaft of the rotating shaft 1101 of the pair of cutter units 1100 is connected to the central shaft 2100 of the reducer 2000. 1101 'is connected, and at the side of the rotary shaft 1101', the rotary shaft gear 1102 '' of the other rotary shaft 1101 '' of the rotary shaft 1101 of the pair of cutter units 1100 is the speed reducer. The second reduction gear 2101 formed on the central axis 2100 of the 2000 is engaged with and rotates. Accordingly, as the driving shaft 3100 of the hydraulic motor 3000 rotates, its rotational force is the central shaft 2100 of the reducer 2000, one rotation shaft 1101 ′ of the pair of cutter units 1100, and the other. It is transmitted to the rotation shaft 1101 ″ in order so that the pair of cutter portions 1100 rotate to crush the crushed object. However, since the structure of the conventional crusher as described above further includes a separate reducer 2000 between the crusher 1000 and the hydraulic motor 3000, the entire crusher may be damaged due to the weight of the reducer 2000. There is a problem that the weight is increased (about 4000kg) as well as occupy a lot of space to be mounted due to the increase in volume due to the reducer (2000). In addition, by using the rotational force of the hydraulic motor 3000 in the end of the structure that rotates all of the rotary shaft 1101 of the cutter portion 1100, of course, in the drive gear 3101 of the hydraulic motor 3000 Complex structure passing through the first reduction gear 2001 of the reducer 2000 and the second reduction gear 2101 of the reduction gear center shaft 2100 through the rotating shaft gear 1102 '' of the other rotating shaft 1101 '' Since the loss of the rotational force transmitted due to the meshing rotation of the spur gears is large, the hydraulic motor 3000 has to exert a lot of force, so the size and weight of the hydraulic motor 3000 itself must also be large. There is. In addition, as the efficiency of the hydraulic motor 3000 decreases as described above, the heat generated in the hydraulic motor 3000 also increases, and therefore, a larger amount of fluid is required to cool the generated heat. There is also a problem that the size and weight of the fluid tank for storing the must also be large.

Therefore, in the present invention, as shown in FIG. 6 and the like, the hydraulic motor 30 is directly connected to the rotary shafts 111 of the pair of cutter units 110 separately, respectively, omitting a separate reducer to transfer driving force. It is characterized by forming a structure. That is, by directly connecting the drive shaft 310 of the hydraulic motor 30 separately to the rotary shaft 111 of the pair of cutter units 110, a separate reducer can be omitted. As shown in Fig. 2, a gear of much larger diameter than the gear formed on the drive shaft of the hydraulic motor must be used and the rotational force must be transmitted to both of the pair of rotating shafts of the pair of cutters connected thereto, thereby increasing the weight and volume. As a result, the weight and volume occupied by the reducer in the crusher are also increased, thereby reducing the weight and volume of the crusher so that it can be loaded into a small tower car. Thus, the present invention omits the reducer itself. By inventing a structure capable of reducing the weight and volume of the entire crusher (that is, the weight of the entire crusher Although it reached about 4 tons, in the present invention, it can be reduced to about 800 kg) Finally, as shown in FIG. 9, a small tower car (a2), which is a small one-ton vehicle, not a conventional 8-ton vehicle. Can be mounted).

In addition, while directly connecting the hydraulic motor 30 to the rotary shaft 111 of the pair of cutter units 110 separately, in particular, the hydraulic motor 30 is not positioned in the same direction, but a pair of cutter portions By placing the 110 in the center so as to face each other, the volume of the crushing unit 10 and the hydraulic motor 30 can be reduced, so that the volume can be installed in a narrow space. It is advantageous to make it possible.

The hydraulic motor 30, which is connected to the crushing unit 10, that is, the pair of cutter units 110 and transmits a driving force, may have one cutter unit among the pair of cutter units 110. Since only the rotating shaft 111 of 110 is rotated, the weight and volume of the motor itself can be reduced (also used as a small-capacity motor), so that the actual total weight is achieved even if two motors are used compared to a single large-capacity motor. Becomes similar, rather, the hydraulic motor 30 is connected directly to the rotary shaft 111 of each one cutter unit 110 to rotate it to reduce the loss in the process of transferring the force is connected in a multi-step as in the prior art Since it is not necessary to exert excessive driving force due to inefficiency (hence, even in the case of using a conventional large-capacity motor, the crushing capacity was 800 kg / hr. In other words, the size of the top vehicle can be significantly reduced while the crushing capacity can be maintained at 500 to 600 kg / hr.) Accordingly, the heat generated in the hydraulic motor 30 can be reduced to cool the generated heat. Since the amount is also small enough, it is possible to reduce the size and weight of the fluid tank for storing the fluid, which is advantageous in that the shredder can be mounted in the small top vehicle a2.

In this case, the hydraulic motor 30 used may be a reducer built-in hydraulic motor, when one embodiment of the structure, as shown in Figure 7, the permanent magnet 320 is installed on the inner peripheral surface of the case, the permanent An armature 330 connected to the first driving shaft 310 ′ is installed on an inner circumferential surface of the magnet 320, and the pinion gear 340 is circumscribed to the gear teeth of the first driving shaft 310 ′. ), And the gear teeth of the reduction gear 350 is inscribed, and the second drive shaft 310 ″ is connected to the reduction gear 350. In this case, power is applied to the permanent magnet 320 of the reduction gear 350. When the armature 330 installed therein is rotated and a rotational force is transmitted through the first drive shaft 310 ′, a rotational force is transmitted to the reduction gear 350 through the pinion gear 340 so that the second driving shaft 310 ′ is rotated. ') Is rotated, the number of rotations of the first drive shaft 310' is rotated Since the speed reduction through the gear 350, the second drive shaft (310 '') is so rotated as appropriate number of speed reduction to increase torque. The structure of the hydraulic motor 30 shown in FIG. 7 is only one embodiment, and the reduced speed built-in hydraulic motor used in the present invention is not limited to having the above structure.

The chip discharge unit 50 is configured to discharge the chip crushed by the crusher 10 to the outside, as shown in Figure 4 and the like below the crusher 10 fixed to the shelf 92 It is located in the crushing unit 10 to be crushed to fall to collect the chip falling to the lower to be discharged to the outside, in particular, a separate storage box (93).

As described above (refer to FIG. 3), the chip discharge part 5000 used in the conventional crusher uses the hydraulic cylinder 5100 to move the pressing plate 5200 forward (① direction) and backward (② direction). Since the method is repeated, the hydraulic cylinder 5100 operates not only continuously in one direction but also operates to repeat forward and backward intermittently, thereby generating noise and vibration whenever the direction of movement is changed. In addition, since the heat generation is increased in the hydraulic cylinder 5100, which intermittently repeats the forward and backward movements, a larger amount of fluid is required to cool the generated heat, thereby storing the fluid. The size and weight of the fluid tank is also inevitably increased, which in turn limits the increase in the weight of the crusher itself and the miniaturization of the mobile tower.

Therefore, in the present invention, as shown in FIG. 4 and the like, the chip discharge part 50 rotates along the circumference of the second rotary shaft 520 and the second rotary shaft 520 by the second hydraulic motor 510. By including the wing portion 530 protruding in a spiral, it is possible to reduce the noise, vibration and heat generation, as well as to reduce the overall weight of the crusher because the work proceeds continuously in only one direction. That is, since the wing portion 530 formed on the second rotary shaft 520 of the chip discharge unit 50 is formed in a spiral shape continuously along the circumference of the second rotary shaft 520, the second rotary shaft Even if 520 continues to rotate only in one direction, the wing 530 may transfer the continuously falling chip in one direction, so that noise due to the change of the movement direction may eliminate the vibration, and the second The second hydraulic motor 510 which generates a driving force to rotate the rotating shaft 520 also does not have to be intermittently operated for the change of direction, but continuously generates constant heat in the same movement direction with the same force, thereby generating heat generated therein. Since the amount of fluid to cool the generated heat is also small, the size and weight of the fluid tank to store the fluid is also reduced. It may be advantageous to finally allow the shredder to be mounted in the compact tower a2 (as shown in FIG. 9).

The weighing unit 70 is configured to check and manage the weight of the shredding object to be shredded, and the billing for the conventional shredding operation is charged in proportion to the size of the top vehicle equipped with the shredder and its working time. This conventional method has been used, but in the conventional method, even if the size of the top vehicle, that is, the weight and volume of the shredder, can be more efficiently shredded, the billing is reduced. The efficiency of the crushing work is rather unreasonable in that it is possible to charge more in small cases, so that the charge is not made in proportion to the amount of work, and also because the hourly charging is performed instead of the weight of the crushed object. There is an absurdity in which charging is not made in proportion to the amount of work and loses the trust of the consumer. There are evils.

Therefore, in the present invention, to solve the above problems and substantially reduce the weight and volume of the shredder itself in order to maximize the mobility and efficiency to improve the irrationality caused in the charging phase in the case of miniaturization of the top vehicle and substantially crushing In order to be charged in proportion to the weight of the crushed object that performed the operation, to form a weighing unit 70 to check and manage the weight of the crushed object to be crushed in advance in the crusher,

The weighing unit 70 is configured to check and manage the weight of the crushing object to be crushed, one side of the crushing unit 10 and the input hopper 91, preferably the crushing unit 10 The back is positioned separately on one side on the shelf 92 is fixed. Referring to FIG. 8, the weight measuring unit 70 includes a measuring plate 710 for supporting a crushed object placed for measurement, and a measuring sensor 720 for measuring the weight of the crushed object pressed on the measuring plate 710. ), A central processing module 730 for arithmetic processing using the measured values measured by the measuring sensor 720, and a communication module 740 for transmitting and receiving data under the control of the central processing module 730. have.

The measuring plate 710 is configured to support the shredding object placed on the weighing unit 70 for measurement, and can also support the shredding object having a weight greater than or equal to a predetermined range, which is located at the top of the weighing unit 70. It is desirable to be formed of a durable material so that.

The measuring sensor 720 is generally located below the measuring plate 710 to measure the weight of the crushed object pressed to the measuring plate 710, and the pressure to the measuring sensor 720 is pressed A pressure sensor that can measure can be used. The measured value measured by the pressure sensor 720 is transmitted to the central processing module 730 to be described later to be used as basic data for calculating billing or various data.

The central processing module 730 is configured to calculate and process various data by using the measured value measured by the measuring sensor 720, cumulative data on the weight of the crushed object measured by the measuring sensor 720, crushed by day Data on workload, cumulative data of shredding work for a specific consumer, work capacity data calculated on the basis of the shredder's work, etc. are calculated, stored and provided so that users can utilize them in their work. A central processing unit (CPU) or the like may be utilized as the central processing module 730, and may be used as the display 94 through a communication module 740 which will be described later and stored in the central processing module 730. Can be sent and received.

The communication module 740 is configured to transmit and receive data under the control of the central processing module 730, and the display 94 or the data calculated and stored in the central processing module 730 using a wired or wireless communication method. Send and receive to your server.

Therefore, the user first checks the weight of the shredding object through the weighing unit 70 before putting the shredding object into the feeding hopper 91, and the weight of the checked shredding object is determined by the weight measuring unit 70. ), And may be recorded and stored, and may be displayed so that a user or the like may visually check it through the display 94 separately installed as necessary. As a result, the billing can be made in proportion to the amount of the shredding object that is actually shredded, so that consumers can be satisfied as well as the weight and size of the shredder through technology development to improve the mobility and efficiency of the shredder. In the case of miniaturization of the tower car equipped with the shredder, the rational cost can be charged in proportion to the work load without being unreasonable in charging, and the use of the small tower car (a2) can reduce the capital investment and maintenance cost. You will have the advantage. In addition, based on the measured data, data on the work efficiency at which the shredding work is performed or data such as the variation of the shredding workload from a particular consumer can be calculated and used separately. The efficiency of the operation can be improved.

Such a shredder according to an embodiment of the present invention can accurately check and manage the weight of the shredding object and can accurately calculate and provide the shredding cost based on this, thereby ensuring the trust of the consumer. The technology development will reduce the weight and size of the shredders, and the users who have miniaturized the shredders will not be charged with irrational charges, and they will be able to reduce equipment investment and maintenance costs by utilizing the small tops. In addition, it is possible to reduce the overall weight of the crusher by applying a structure omitted a separate reducer, mounted on a small tower (a2) to increase mobility and usability, as well as separate rotary shafts of a pair of cutters By placing a pair of reducer-embedded hydraulic motors directly connected to each other, the volume of the crushing unit and the hydraulic motor are reduced so that they can be mounted in a narrow space, and the efficiency of the force transmitted from the hydraulic motor to the pair of cutter units is reduced. By reducing the heat generated in the hydraulic motor and the chip discharge part discharging the chipped to the outside can proceed continuously in only one direction to reduce the noise, vibration and heat generation fluid tank and final This can achieve miniaturization of the top car.

In the above, the Applicant has described preferred embodiments of the present invention, but these embodiments are merely one embodiment for implementing the technical idea of the present invention, and any changes or modifications may be made as long as the technical idea of the present invention is implemented. Should be interpreted as being within the scope.
