Description

  In the present invention, when a plurality of products are manufactured by cutting a desired length from a standard steel plate (hereinafter referred to as a workpiece) by a laser processing machine or a punch press or the like, The product separating apparatus for separating the product connected and held by the workpiece from the workpiece.

  When cutting multiple products from a workpiece using a plate processing machine such as a laser processing machine or a punch press, the product is removed from the workpiece so that the processed product does not come off the workpiece during processing. In general, so-called microjoint processing is performed in which a product is held on a work by leaving a microjoint between the product and the work at an appropriate portion on the outer periphery of the product without being completely separated.

  For example, when a product Pn (n = 1, 2, 3,...) Having a shape as shown in FIG. 9 is processed by a punch press, appropriate punched holes a and b are formed in the outer shape of the product Pn, and the product At the corner of Pn, microjoint processing is performed in which the product Pn is held on the workpiece W leaving a microjoint M of about 0.10 to 0.20 mm between the product Pn and the workpiece W. Then, after all the products Pn have been processed, the workpiece W is unloaded from the punch press and separated into the product Pn and the remaining material (skeleton) S.

The product Pn micro-joint processed to such a workpiece W always requires a process of separating the product Pn and the remaining material S from the workpiece W after the cutting process. Conventionally, as the product separation method, the following method is used. It has been commonly used.
1. The workpiece W is bent by the operator holding the end of the workpiece W up and down, and as a result, the bending load is repeatedly applied to the micro joint M, and the micro joint M is broken and cut by the fatigue failure. A method of separating Pn from the workpiece W.
2. A method of separating the product Pn from the workpiece W by hitting the product Pn with a rubber hammer or the like to cause plastic deformation.

  However, since the method is a manual operation, there is a risk that the end of the workpiece W may be injured, and the product Pn may be deformed or the product Pn may be damaged. Therefore, the work required skill, and the work took time and was inefficient. In addition, the product Pn can be efficiently separated by these methods only for a thin plate having a thickness of 1 mm or less, and in the case of a thickness greater than that, the work itself becomes heavy labor and the product Pn is reliably separated. Is difficult.

  As a product separation apparatus that solves such a problem, the one shown in FIGS. 7 and 8 is known. The product separating apparatus is a product separating apparatus that vibrates a workpiece having products connected by micro joints to separate the product from the workpiece, and includes a vibrating member 50 on which the workpiece W is placed and supports the vibrating member 50. The cam member 51, the eccentric cam 52 that vibrates the vibration member 50 via the cam house 51, the drive motor 53 that rotates the eccentric cam 52, and the vibration member 50. And a repulsion member 54 that gives a repulsive impact force when the workpiece W vibrates due to vibration.

  When the drive shaft 55 is rotated by the drive motor 53, the eccentric cam 52 rotates and the vibration member 50 vibrates in the vertical direction indicated by the arrow A as shown in FIG. Then, the workpiece W placed on the vibrating member 50 is flipped upward and collides with the repelling member 54. Due to this collision, the workpiece W receives a repulsive impact force and rebounds downward, vibrates in the vertical direction indicated by the arrow B, and the impact force is doubled.

  By continuously rotating the drive motor 53 at a high speed, the vibration in the vertical direction of the vibration member 50 continues, and when vibration and impact force are repeatedly applied to the workpiece W, the difference in vibration between the workpiece W and the product Pn. Will occur. This difference in vibration acts on the micro joint M, local stress concentration causes plastic deformation, and the micro joint M is broken and cut by fatigue failure, so that the product Pn is separated from the workpiece W.

  As shown in FIG. 7, the product Pn thus separated falls downward from between the vibrating members 50, and is accumulated in the product receiving box 57 through the product takeout chute 56. In addition, the work W is carried in from the carry-in entrance 58, and is placed on the end of the vibration member 50. The drive motor 53 is driven at a low speed by an inverter, thereby being an eccentric cam 52 and a stepping mechanism. The rotating disk 59 rotates, and the workpiece W is sequentially placed on the vibrating member 50 that gently vibrates.

In such a conventional product separating apparatus, the vibration exciting mechanism that applies the vertical vibration to the workpiece W is composed of the eccentric cam 52, the cam house 51, the vibration member 50, and the repulsion member 54. As the work W collides and bounces back, the repulsive impact force is doubled. Therefore, with relatively small power and the vibration mechanism is small, the response to vibration control is good and the necessary vibration is It can be generated in a short time, and the product Pn can be efficiently separated from the workpiece W in a short time.
JP-A-10-86099

  However, in such a conventional product separating apparatus, the pair of cam houses 51 and the vibration member 50 bridged on the cam house 51 vibrate by the eccentric cam 52, so that the entire workpiece W is vibrated in the vertical direction. The product Pn is scratched by the mechanism that separates the product Pn from the workpiece W by the impact force that the workpiece W collides with the repelling member 54 and bounces back and the impact force when the workpiece W drops on the vibration member 50. There is a fear, and it is difficult to suppress the generation of noise.

  In addition, since the micro joint M is subjected to fatigue failure by the impact force at the time of collision, it breaks and cuts, so there is a problem that it takes time to reliably and safely separate all products Pn. .

  The present invention has been made in order to solve this problem in view of the above-described conventional problems, and allows the product to be efficiently separated from the workpiece in a short time, and the product is not damaged regardless of the thickness of the workpiece. An object of the present invention is to provide a product separation device that can be safely separated.

  In order to achieve such an object, the invention according to claim 1 of the present invention is a product separating apparatus for vibrating a workpiece in which a product is held by a micro joint and separating the product from the workpiece. A plurality of rotating shafts horizontally straddled on the top, a plurality of cam members mounted at equal axial positions of these rotating shafts, and a predetermined amount of slack in a state of being bridged between the cam members of the rotating shafts And the work is placed on the vibration belt, and the rotation shaft is rotated by the drive motor through the power transmission means, and rotates integrally with the rotation shaft. A configuration is adopted in which the workpiece is moved up and down by vibrating the vibration belt in the vertical direction with a predetermined period by the cam member, and the product and the remaining material are separated from the workpiece.

  Since such a configuration is adopted, the workpiece placed on the vibration belt moves up and down along the vibration belt's undulation in a curved state, not in a horizontal state, so that a random repeated bending load is applied to the micro joint. The micro joint is easily broken and cut by fatigue failure due to fatigue failure. Accordingly, the product can be efficiently separated from the workpiece in a short time, and the product can be reliably and safely separated from the workpiece regardless of the thickness of the workpiece. Further, the jumping of the product separated from the workpiece can be buffered by the vibration belt, and the dropped product can be prevented from biting into the cam member or the like.

  Further, the invention according to claim 2 includes a plurality of conveying rollers provided in a lower part of the vibration mechanism and provided in two upper and lower stages, and a conveying belt stretched between the conveying rollers.

A plate-like stopper inserted, and a chuck member fixed to the outside of the stopper and detachably attached to the guide shaft, and the distance between the stoppers corresponding to the width of the workpiece Since the width adjusting mechanism is adjusted, the horizontal dimension of the workpiece can be easily accommodated and the horizontal movement of the workpiece can be restricted.

  Preferably, as in the invention described in claim 4, if the stopper is formed in a substantially L-shaped cross section having a restriction frame extending in the longitudinal direction at an upper portion thereof and projecting inwardly, Excessive jumping can be controlled with a simple configuration.

  Further, as in the invention described in claim 5, since the phase of the cam member is made different with respect to the rotation shaft, the point for supporting the workpiece, that is, the workpiece is lowered as the cam member rotates. The point pushed up from the surface fluctuates randomly, and an excitation force that curves the workpiece can be applied. Thereby, a more random repeated bending load is applied to the micro joint, and the micro joint can be easily broken and cut by fatigue failure.

  Preferably, as in the invention described in claim 6, if at least one of the rotating shafts is rotated in the opposite direction to the other rotating shafts, the excitation force for further bending the workpiece is randomly generated. Can be granted.

  According to a seventh aspect of the present invention, the cam member includes a pair of yokes fixed to the rotating shaft, a pair of fixed shafts connecting the yokes, and a plurality of the shafts attached to the fixed shafts. Since the rolling bearing is provided, the vibrating belt can be pushed up while rolling instead of sliding. Thereby, abrasion of the vibration belt and the cam member can be suppressed as much as possible, durability can be improved, and generation of noise can be further suppressed.

  The product separation device of the present invention is a product separation device that vibrates a workpiece in which a product is held by a microjoint and separates the product from the workpiece. A plurality of cam members mounted at equidistant positions in the axial direction of the rotary shafts, and a vibration belt stretched between the cam members of the rotary shafts. The rotating shaft is rotated by a drive motor through power transmission means, and the vibrating belt is vibrated in a predetermined cycle by the cam member rotating integrally with the rotating shaft.

To move up and down along the dough, random repetitive bending load is loaded on the micro joints, micro joints easily broken, is cleaved by fatigue fracture. Accordingly, the product can be efficiently separated from the workpiece in a short time, and the product can be reliably and safely separated from the workpiece regardless of the thickness of the workpiece. Further, the jumping of the product separated from the workpiece can be buffered by the vibration belt, and the dropped product can be prevented from biting into the cam member or the like.

It was conveyed outside.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
1 is a front view showing an embodiment of a product separation device according to the present invention, FIG. 2 is a plan view of FIG. 1, FIG. 3 is a side view of FIG. 1, and FIG. 4 is a line IV-IV of FIG. FIG.
The product separating apparatus 1 includes a vibration mechanism 2, a product transport mechanism 3, and a workpiece width adjustment mechanism 4.

  The vibration mechanism 2 includes six rotating shafts 6 horizontally straddled on the upper portion of the base 5, four cam rollers 7 mounted at equal axial positions of the respective rotating shafts 6, and the respective rotating shafts 6. And a vibrating belt 8 stretched between the cam rollers 7. The rotating shaft 6 is rotatably supported by a pair of rolling bearings 9 and 9, and a sprocket 10 is fixed to one end portion thereof. On the other hand, a drive motor 11 is disposed in the lower center of the base 5, and a motor sprocket 13 is fixed to the motor shaft 12. As shown in FIG. 1, a chain 14 is stretched between the motor sprocket 13 and the sprocket 10, and the rotation of the drive motor 11 is transmitted to each rotary shaft 6 through a pair of intermediate sprockets 15.

  In the present embodiment, as shown in FIG. 1, the chain 14 includes two sprockets 10 fixed to the end portions of the six rotation shafts 6, the two on the left and right of the two sprockets 10, 10 from the top to the center. The sprockets 10 and 10 are suspended below. Thereby, only the two rotation shafts 6 and 6 located in the center rotate in the direction opposite to the rotation of the other four rotation shafts 6. Here, the means for transmitting the rotation of the drive motor 11 to the rotating shaft 6 by the chain 14 is exemplified, but the present invention is not limited to this, and a belt transmitting means such as a timing belt may be used.

  As shown in FIG. 5, the cam roller 7 includes a pair of yokes 16, 16 fixed to the rotary shaft 6, a pair of fixed shafts 17, 17 connecting the yokes 16, 16, 17 and a plurality of (five) rolling bearings 18 attached to 17. The rolling bearing 18 includes an outer ring 18a and an inner ring (not shown) press-fitted into the fixed shaft 17 via a rolling element (not shown) in the outer ring 18a. Spacers 19 are interposed between the inner rings and between the inner ring and the yoke 16 so that the rolling bearing 18 is positioned in the axial direction and the outer rings 18 a and 18 a or the outer ring 18 a and the yoke 16 do not contact each other. Accordingly, the outer ring 18 a can freely rotate with respect to the fixed shaft 17.

  In addition, although the cam roller 7 provided with the several rolling bearing 18 was illustrated here, it is not restricted to this, What is necessary is just the cam member formed in the width substantially the same as the width | variety of the vibration belt 8 mentioned later, for example, a disc An eccentric cam in which the rotation center is offset by a predetermined amount, or a cam member having an outer peripheral surface having an irregular shape such as an ellipse may be used.

  The vibration belt 8 is made of resin, rubber, or a combination thereof, and is fixed to both ends of the base 5 with a predetermined amount of slack. As the rotating shaft 6 rotates, the cam roller 7 rotates, so that the vibration belt 8 is pushed by the rolling bearing 18 of the cam roller 7 and vibrates at a predetermined cycle in the vertical direction. The workpiece W holding the micro joint processed product is placed on the vibration belt 8 and moves up and down as the vibration belt 8 vibrates.

  The product transport mechanism 3 is disposed below the vibration mechanism 2. As shown in FIG. 4, the transport mechanism 3 includes a plurality of transport rollers 20 provided in two upper and lower stages, a pulley 23 fixed to a motor shaft 22 of a transport motor 21, and the pulley 23 and each transport roller. The conveyor belt 24 is stretched between 20 and constitutes a so-called conveyor mechanism. Then, the product separated from the workpiece W naturally falls on the conveyor belt 24 and is sent to a product receiving box (not shown) disposed at one end of the product separating apparatus 1. Such a transport mechanism 3 can efficiently transport the product outside the apparatus without damaging the product, and can automatically transport the product without taking up space.

  The width of the workpiece W is appropriately selected depending on the shape and size of the product. In this embodiment, the width adjusting mechanism 4 is provided so as to correspond to the width of the workpiece W, for example, a width dimension of 90 to 120 mm. For example, as shown in FIG. 2, the width adjusting mechanism 4 includes three guide shafts 25 straddling the upper portion of the base 5, and plates slidably inserted at both ends of the guide shafts 25. And a chuck member 27 that is externally inserted into the central guide shaft 25 and fixed to the outside of the stopper 26. The stopper 26 is formed in a substantially L-shaped cross section having a restriction frame 26a extending in the longitudinal direction at an upper portion thereof and projecting inwardly. Then, the pair of stoppers 26 are slid along the guide shaft 25 to a predetermined position in accordance with the width dimension of the workpiece W, and the lever 28 of the chuck member 27 is rotated. As the lever 28 rotates, a pin (not shown) comes into contact with the guide shaft 25 and the stopper 26 is positioned and fixed to the guide shaft 25. Here, the guide shaft 25 is disposed between the rotary shafts 6 on the substantially same plane as the rotary shaft 6 constituting the vibration exciting mechanism 2.

  By such a product width adjusting mechanism 4, the horizontal movement of the workpiece W can be regulated in a simple manner corresponding to the width dimension of the workpiece W. Moreover, since the stopper 26 is formed in a substantially L-shaped cross section having the regulation frame 26a, excessive jumping of the workpiece W can be regulated with a simple configuration.

FIG. 6 is an operation explanatory diagram of a main part of the vibration mechanism according to the present embodiment. The operation of separating the product from the workpiece will be described with reference to FIG.
The cam rollers 7 and 7 fixed at the axially equidistant positions of the rotating shaft 6 are set to a predetermined phase with respect to the rotating shaft 6. In a state of being bridged so as to be in contact with the outer circumferences of these cam rollers 7, 7, the vibration belt 8 is set and stretched to a predetermined slack amount. The workpiece W is placed on the vibration belt 8. Since the phases of the cam rollers 7 and 7 are different from each other, the workpiece W is supported by at least three cam rollers 7 positioned at the uppermost position.

  When the drive motor 11 is rotated in such a state, the respective rotation shafts 6 are rotated via the chain 14, and the cam roller 7 is rotated integrally with the rotation shaft 6. Then, as the cam roller 7 rotates, the vibration belt 8 locally vibrates in the vertical direction at a predetermined cycle, and undulates as a whole.

  The workpiece W placed on the vibration belt 8 moves up and down along the undulations of the vibration belt 8. As described above, the workpiece W is moved by at least three cam rollers 7 positioned at the uppermost position. Since it is supported, the point is supported in a curved state, not in a horizontal state, coupled with its own weight.

  Further, the cam rollers 7 have different phases, and only the central two cam rollers 7 are set to rotate in the opposite direction to the other cam rollers 7. The supporting point, that is, the point at which the workpiece W is pushed up from below changes randomly, and an excitation force that curves the workpiece W can be applied. As a result, as if conventionally performed, the operator has a motion similar to the operation of bending the workpiece W by holding the end of the workpiece W up and down and bending the workpiece W. Repeated bending load is applied, and the micro joint is easily broken and cut by fatigue failure. Therefore, the product can be efficiently separated from the workpiece W in a short time, and the product can be reliably and safely separated from the workpiece W regardless of the thickness of the workpiece W. In particular, products of any thickness and size are separated, such as products with a resin coating as a rust preventive coating on the surface, products made of soft metals such as aluminum alloys, or stainless steel products with high toughness. It is suitable for.

  Further, since the workpiece W is not pushed up directly by the cam roller 7 but is pushed up while being curved via the vibration belt 8, the product is not damaged and the generation of noise can be suppressed. Furthermore, it is possible to buffer the jumping of the product separated from the workpiece W, and it is possible to prevent the dropped product from biting into the cam roller 7 or the like.

  In this embodiment, since the cam roller 7 is composed of a plurality of rolling bearings 18, the vibration belt 8 can be pushed up while rolling instead of sliding. Thereby, abrasion of the vibration belt 8 and the cam roller 7 can be suppressed as much as possible, durability can be improved, and generation of noise can be further suppressed.

  The embodiment of the present invention has been described above, but the present invention is not limited to such an embodiment, and is merely an example, and various modifications can be made without departing from the scope of the present invention. Of course, the scope of the present invention is indicated by the description of the scope of claims, and further, the equivalent meanings described in the scope of claims and all modifications within the scope of the scope of the present invention are included.
