Description

  The present invention relates to a metal unraveling machine and a metal unraveling method. More particularly, the present invention relates to a metal unraveling machine and a metal unraveling method for applying vibration to a lump of metal pieces to be entangled and separating the metal parts.

As a technique in this field, a method described in Patent Document 1 is known. According to this technique, a spiral spring is supplied in an entangled state, and an operator puts a lump of the entangled spring in a container provided in a spring unraveling machine. The container receives an impact force by an impact generator that hits the bottom surface. As a result, a lump of entangled springs jumps and the spring is separated into one or several units. An obstacle is provided in the container, and the spring is further separated and discharged from the discharge port.
This is because when the bottom surface of the container is struck with a hammer, a lump of springs receives an impact, and the lump jumps, and as a result, the springs are separated into one or several units.

  However, since this method generates vibration by the rotation of the motor, it is necessary to change the driving voltage or replace the parts of the hammer portion when it is desired to change the vibration conditions. In this way, it takes time to change the setup, and it is difficult to easily cope with the type of spring. Furthermore, since the vibration is generated by hitting the bottom surface of the container from below, it is difficult to change the direction of the vibration. Further, this technique is a spring loosening machine limited to a spiral-shaped spring, and the degree of correspondence with respect to a metal fitting processed into a shape easily entangled other than the spring is not clear.

JP 2006-160513 A

  The present invention has been made in view of the above problems, and can be applied to metal fittings processed into a shape that is easily entangled other than a spiral spring, and the direction, size, and other conditions of vibration can be easily applied. It is an object of the present invention to provide a bracket unraveling machine that can be changed, and to provide a bracket unraveling method.

  In order to solve the above-mentioned problems, a metal unraveling machine according to the present invention is (1) a metal fitting that separates the metal fittings into one or several pieces from a lump in a state where a plurality of metal pieces processed into a shape that easily entangles with each other. A loosening machine, wherein a mesh plate portion on which the lumps to be entangled are set, at least two vibration portions that give vibration to the mesh plate portion, a control unit that independently controls the operation of the vibration portion, and the vibration And a vibration transmitting portion for transmitting the vibration of the portion to the mesh plate portion, and the metal plate separated from the mesh drops when the mesh plate portion vibrates in the vertical direction.

  In the metal unraveling machine of the present invention, vibration is generated by the vibration unit whose movement is controlled by the control unit. Thereby, the magnitude | size of a vibration, a period, and other conditions can be changed easily and the conditions according to the shape and magnitude | size of a metal fitting can be set easily. In addition, since the vibration portion is provided at a plurality of locations, it is possible to control a complicated movement of the mesh plate portion, and an efficient metal loosening condition can be obtained. In addition to the vibration generation position in the vertical direction, the vibration unit can also be provided in a horizontal vibration generation position, so that it can generate horizontal vibration in addition to the vertical vibration. This means that more effective vibration conditions suitable for the shape and size of the metal fitting can be obtained.

  The vibration unit may be an air cylinder that uses air as a drive source. The mesh plate part may be a braided metal wire, for example, so that a mesh can be formed, and the size of a set of meshes is such that a lump of metal fittings does not pass and is separated into one or several pieces. The size that can be passed through. The shape of the mesh may be quadrangular, pentagonal, or circular, and the shape is not particularly limited.

  As the control unit, for example, PLC (Programming Logic Control) control can be used. For example, when the vibration part is provided at the four corners of a square mesh plate part, the period of vibration can be set by shifting 90 degrees clockwise. By setting in this way, a lump of metal fittings in the net plate part is flipped up in a shorter period and more effectively separated.

  More preferably, in the metal unraveling machine of the present invention, (2) when at least one part of the front or back surface of the mesh plate portion is connected to the elastic material, and the mesh plate portion moves upward or downward, the elastic material (1) is characterized in that a reaction force and an impact force are applied to the entangled mass.

  In the metal unraveling machine of the present invention, the net plate part is connected to the elastic material, and the reaction force of the elastic material is superimposed on the vibration by the vibration part. Thus, for example, when the reaction force of the elastic material is applied upward, the lump of metal fittings placed on the mesh plate portion is accelerated by the reaction force of the elastic material when the vibration is upward. Shows a jumping movement. Thereby, the loosening effect of the entangled metal fittings is further strengthened, so that the metal parts can be separated more effectively.

  More preferably, the metal unraveling machine according to the present invention is (3) the one described in (1) or (2) in which a plurality of the vibration parts are controlled to vibrate in the same direction at the same period.

  Since the plurality of vibrating parts vibrate in the same direction with the same period in the metal unraveling machine of the present invention, a lump of metal parts placed on the mesh plate part receives larger energy. Thereby, the loosening effect of the entangled metal fittings is further strengthened, so that the metal parts can be separated more effectively.

  More preferably, the metal unraveling machine according to the present invention is (4) the one described in (1) or (2), wherein the plurality of vibrating parts are controlled so as to vibrate at different periods.

  In the metal unraveling machine of the present invention, a plurality of vibration parts vibrate with different periods, and therefore, more appropriate vibration can be given according to the type of metal fittings. Thereby, the loosening effect of the entangled metal fittings is further strengthened, so that the metal parts can be separated more effectively.

  More preferably, the metal unraveling method of the present invention is (5) a metal unraveling method that separates the metal fittings into one or several pieces from a lump in a state where a plurality of metal fittings processed into a shape easily entangled with each other. Then, the method includes a step of setting the entangled lump on the mesh plate portion, a step of applying vibration to the mesh plate portion, and a step of superimposing an impact force due to a reaction force of an elastic material on the vibration.

  The metal unraveling method of the present invention includes a vibration part that generates vibration and an elastic material that generates elastic reaction force. For example, this. An upward impact force can be applied while applying periodic vibrations to a lump of metal fittings. As a result, the loosening effect of the tangled metal fitting is strengthened, so that more effective separation is achieved.

  <Sieving Device> As shown in FIGS. 1 to 3, the sieving device 30 includes a mesh plate portion 31 and a support portion (a part of the vibration device and a part of the elastic device) that supports the mesh plate portion 31. Support portions (a part of the vibration device and a part of the elastic device) are provided on the upper and lower surfaces of the mesh plate portion 31, and the support of the lower surface is the vibration portion 41 directly attached to the base 10 and the vibration transmission portion extending therefrom. 42, which is made at the tip of the vibration transmitting portion 42 located at the apex of the quadrangle. The upper surface is supported by the elastic member 21 attached to the tip of the support column 25 extending from the four corners of the base 10 and is formed at the tip of the elastic member 21 extending obliquely inwardly downward.

<Vibration Device> As shown in FIGS. 1 to 3, the vibration device 40 includes a vibration unit 41 and a vibration transmission unit 42. In the present embodiment, an air cylinder is used for the vibration part 41. An air cylinder is an actuator that converts air pressure into linear motion. The linear motion is transmitted to the mesh plate portion 31 of the sieving device 30 through the piston rod (vibration transmitting portion 42). In the present embodiment, as shown in FIGS. 1 and 2, a set of vibration devices 40 installed on the base 10 are provided at the four corners of the mesh plate portion 31.

  <Elastic Device> As shown in FIGS. 1 to 3, the elastic device 20 includes an elastic material 21 having an elastic body of a spiral spring and a support column 25 that supports the elastic material 21 at its upper end. In this embodiment, the elastic material 21 is a piano wire processed into a spiral spring. The elastic material 21 is not limited to this, and may be rubber or a leaf spring. As shown in FIGS. 1 to 3, the support column 25 is a column that supports the elastic member 21 that is installed at a position surrounding the net plate portion 31 so as to extend in the four corners of the base 10 in the height direction.

  <Sieving Operation> As shown in FIGS. 1 to 3, the mesh plate portion 31 includes a main body 32 in which metal horizontal bars 33 and vertical bars 34 are assembled in a mesh shape, and mesh plate portions 31 at four corners. A connecting ring 35 for holding in the air is provided. The mesh of the mesh plate portion 31 is larger than the size of the metal fitting 100 and smaller than the mass 110 of the metal fitting 100 entangled, and the mass 110 is set on this one or several pieces. The metal fittings 100 separated into two drops downward from the mesh.

  As shown in FIG. 3, the main body 32 of the net plate portion 31 uses the same metal as the horizontal bar 33 and the vertical bar 34, and has the same thickness, and the mesh formed is substantially square. The main body 32 has a strength sufficient to prevent damage and deformation due to applied vibrations, and has a rigidity necessary for jumping up the lump 110 of the tangled metal fittings 100 thereon.

  As shown in FIG. 4, the connecting rings 35 are provided at the four corners of the mesh plate portion 31. The connecting ring 35 is a component provided to hold the net plate portion 31 in a hollow state. The connection ring 35 on the upper surface connects the mesh plate portion 31 and the elastic material 21 by being connected to the connection ring 22 of the elastic material 21. The connecting ring 35 on the lower surface is connected to the connecting ring 43 of the vibration transmitting unit 42, thereby connecting the net plate unit 31 and the vibrating unit 41. The connection is not firmly fixed by screw fastening or a bonding material, but is preferably performed in a state where it can move freely so as not to impair the energy of inherent vibration. In the present embodiment, the connection is formed by engagement between the rings, and the connection rings 35, 22, 43 can move freely without reducing the inherent vibration.

  As shown in FIG. 4, the connection ring 35 on the lower surface is connected to the connection ring 43 of the vibration transmission unit 42 extending from the vibration unit 41 fixed to the base 10. The vibration transmission part 42 is a metal rod extending in a straight line, the base end is connected to the vibration part 41, and the tip is connected to the net plate part 31 via the connection ring 43. Thereby, the periodic vibration generated in the vibration part 41 is transmitted to the mesh plate part 31.

The connection ring 35 on the upper surface is connected to the connection ring 22 on the lower end side of the elastic member 21, as shown in FIG. The connection is made in such a way that the inherent vibrational energy can be moved freely without loss. As a result, the reaction force from the elastic material 21 is transmitted to the mesh plate portion 31. That is, the upward tension is superimposed on the mesh plate portion 31 to which periodic vibration is applied.

  <Characteristics of generated vibration> The characteristics of vibration will be described with reference to the drawings. FIG. 5 is a conceptual diagram showing a state in which vibration and impact are transmitted to the mesh plate portion. FIG. 6 is a process diagram showing a state in which a lump of metal pieces entangled by the same metal unraveling machine is unwound, and (a) is a diagram showing a state in which a lump of metal pieces entangled with the mesh plate is set. (b) is a figure which shows the state in which a vibration is added to a net | network board part, and the lump of metal fittings jumps, (c) is a figure which shows the state from which one metal metal piece or several metal parts are isolate | separated from the lump which becomes tangled.

  As shown in FIG. 5, the force applied to the mesh plate portion 31 is obtained by superimposing the periodic vibration generated in the vibrating portion 41 and the upward tension generated in the elastic material 21. Thereby, the lump 110 of the entangled metal fittings 100 placed on the mesh plate portion 31 moves so as to periodically jump on the mesh plate portion 31, and receives a drop impact due to its own weight each time. The drop impact at this time effectively acts to separate the tangled metal fittings 100 into one or several pieces as compared with the impact caused simply by periodic vibration. This is a finding obtained through experiments and experience.

  As shown in FIG. 6B, the lump 110 of the tangled metal fitting 100 that has continuously received a drop impact is loosened each time it is dropped, and mainly the bottom surface of the lump 110. The metal fitting 100 is separated from the side by one or several units. The separated metal fitting 100 falls from the mesh of the mesh plate portion 31 and is carried on the work shooter 51 to a work tray (not shown).

  As time passes for the vibration operation, the metal fitting 100 continues to be separated from the lump 110 as shown in FIG. 6C, so that the lump 110 becomes smaller and the entanglement becomes loose. Finally, the lump 110 is not separated into the metal fitting 100.

<Characteristic Vibration> In the present embodiment, one air cylinder is provided at each of the four corners of the screen plate portion 31 of the sieving device 30, and the program is individually controlled. Thereby, a characteristic combination of vibrations can be easily realized, and vibration conditions corresponding to the size and shape of the metal fitting 100 can be given.
For example, in the case of vibrations in which the amplitudes and periods of four air cylinders are all synchronized, they are given to a lump 110 of metal fittings 100 in which periodic vertical movements are entangled. For example, when four air cylinders vibrate with a period shifted by 90 degrees clockwise, the lump 110 of the tangled metal fitting 100 rolls clockwise or counterclockwise in addition to periodic vertical movement. Power works.

  In addition, the vibration conditions corresponding to the shape and size of the metal fitting 100 can be easily set by individually controlling the four air cylinders as appropriate. Thereby, the lump 110 of the tangled metal fittings 100 can be loosened into one or several units.

<Effect> The metal unraveling machine 1 according to this embodiment is provided with periodic vertical vibrations by an air cylinder. Thereby, the metal unraveling machine 1 having a simple structure and relatively inexpensive and effective can be obtained.
The metal brazing machine 1 according to the present embodiment includes one air cylinder at each of the four corners of the mesh plate portion 31. Thereby, since the vibration can be uniformly applied to the entire net plate portion 31 with a compact air cylinder, the metal unwinding machine 1 having a simple structure and relatively inexpensive can be obtained.

-The metal brazing machine 1 which concerns on this embodiment can control four air cylinders separately. Thereby, since the vibration condition according to the shape and size of the metal fitting 100 can be easily set, the lump 110 of the tangled metal fitting 100 can be loosened into one or several units.
-The metal unraveling machine 1 which concerns on this embodiment can be set to the conditions which all the amplitudes and periods of four air cylinders synchronized. Thereby, since the periodic up and down movement is given to the lump 110 of the metal fitting 100 intertwined, the lump 110 is efficiently loosened.

-The metal loosening machine 1 which concerns on this embodiment can set the conditions from which the four air cylinders shifted | deviated the period 90 degree | times clockwise. Thereby, in addition to the periodic vertical movement, a force that rolls clockwise or counterclockwise acts on the lump 110 of the tangled metal fitting 100, so that the lump 110 is efficiently loosened.
The metal unraveling machine 1 according to this embodiment includes a spiral elastic material 21, and the elastic material 21 is suspended obliquely by a support column 25 and supports the net plate portion 31 at the tip. Thereby, in addition to the periodic vibration, upward elastic force is applied to the mesh plate portion 31. As a result, the lump 110 of the tangled metal fittings 100 placed on the mesh plate portion 31 receives an impact force that pushes up during vertical movement. Thereby, the lump 110 is loosened efficiently.
