Abstract

An object of the present invention is to provide a low-cost component supply device capable of preventing vibration stop of a vibrating rail. A basket 10 formed in a mortar shape capable of storing a large number of screws W, a scoop plate 20 swingable upward from the bottom of the basket 10, and the screws scooped up by the swing of the scoop plate 20. In a component supply device comprising transport surfaces 30R and 30L for suspending W and vibrating rails 30 for vibrating and transporting the screws W from inside the basket 10 to the front of the basket 10, the vibrating rails 30 are provided on both sides thereof. A non-vibration plate 5 is arranged on the surface. This makes it difficult for the screws W stored in the basket 10 to come into direct contact with the vibrating conveying rails 30, so that vibration failure of the vibrating rails 30 is less likely to occur as in the conventional case. Therefore, the component supply device 1 of the present invention can stably convey the screw W by vibration. [Selection drawing] Fig. 2

Description

  The present invention relates to a component supply device that scoops up a basket from which a large number of components are stored, supplies the components to a vibration rail, and aligns and conveys the components forward.

  As shown in Patent Document 1, a conventional component supply device is a basket that can store a large number of screws, which is an example of a component, a rake plate that can swing upward from below the basket, and a swing of the rake plate. And a vibration rail that suspends and supports the screw that has been scooped up. One end of the vibration rail is disposed in the basket, and the other end is configured to extend forward of the basket. Moreover, the vibration rail is connected to the vibrator, and is configured to be able to sequentially convey forward by vibrating the suspended screw.

  However, many screws stored in the basket may be difficult to release from the state where each of them is entangled and entangled as disclosed in Patent Document 2. That is, the conventional component supply device has a problem that the screws in the basket are tightly entangled and cannot be broken up even if the rake plate is swung.

  Therefore, a conventional component supply device that solves the above-described problem is disclosed in Patent Document 2. The conventional component supply apparatus includes a basket having a plurality of inclined surfaces formed in a mortar shape toward the rake plate located at a bottom dead center, and a plate that reciprocates vertically from below to above the basket. Be prepared. Thereby, the conventional component supply apparatus can release the screw entangled in the basket by the reciprocating motion of the plate, so that the screw can be supplied to the rake plate and the vibration rail.

  However, the conventional component supply apparatus has to include the plate and a cylinder that reciprocally moves the plate up and down, and thus has a problem that the cost increases and the drive control of the cylinder becomes complicated.

  Further, in the conventional component supply device, the basket has a mortar-shaped inclined surface, so that a large number of screws stored therein gather together along the angle of the inclined surface. As a result, both side surfaces on one end side of the vibration rail that partially protrudes into the basket are always pressed by the screw. Therefore, the conventional component supply device directly contacts and presses both side surfaces of the vibration rail even if the screws stored in the basket are not tightly intertwined. There was also the problem of causing a state that did not vibrate completely.

  The present invention includes a basket formed in a bowl shape that can store a large number of headed parts, a scooping plate that can swing upward from below the basket, and the headed part that is scooped up by swinging of the scooping plate. A component supply device comprising a suspension rail and a vibration rail that vibrates and conveys the headed component from the inside of the basket to the front of the basket, wherein the vibration rail has non-vibration plates arranged on both sides thereof. It is characterized by comprising. The non-vibration plate is arranged at a position lower than the vibration rail, and a predetermined space is provided so that a defective headed component lying on the conveyance surface of the vibration rail can easily slide down into the basket. It is characterized by comprising. Further, the vibration-free plate is characterized in that its thickness is set to be equal to or less than a shaft diameter of the headed component. Furthermore, the non-vibration plate is formed by forming a slope on the upper surface of the non-vibrating plate so that the headed component can easily slide into the basket.

  In the component supply device of the present invention, the vibration-free plates are arranged on both side surfaces of the vibration rail projecting in the basket, so that a headed component in the basket does not directly touch both side surfaces of the vibration rail. Therefore, there is an advantage that the headed parts supplied on the vibration rail can be reliably transported forward, because the vibration of the vibration rail is significantly weakened unlike the conventional case, and is not easily in a state where it does not vibrate completely. In addition, the parts supply apparatus of the present invention does not have a vibration-free plate and a cylinder for untangling the headed parts in the basket as in the prior art, and therefore has an advantage that costs can be reduced and control can be facilitated.

  Furthermore, in the component supply device of the present invention, since the mounting height of the vibration-free plate is disposed at a position lower than the conveyance surface of the vibration rail, the head with a bad posture lying on the conveyance surface of the vibration rail is provided. Parts are easy to slide down from the side of the vibration rail. This is obvious when compared with the case where the upper surface of the vibration-free plate is arranged at the same height as the conveying surface, and has a small area for supporting the headed component in a poor posture and provides a sliding space in the sliding direction. This is because it is possible. In addition, since the vibration-free plate is arranged at a mounting height that is one step lower than the conveyance surface of the vibration rail in this way, the head of a headed component suspended in a normal vertical position on the vibration rail is Even if it is formed in an umbrella shape, it does not interfere with the non-vibrating non-vibrating plate and is stably supplied to the front. Therefore, the component supply device according to the present invention not only easily slides a defective headed component into the basket, but also stably transports an umbrella-shaped headed component. There is also an advantage of being able to do it. Furthermore, since the thickness of the vibration-free plate is set to be less than the diameter of the shaft portion of the component, the component supply device of the present invention is unlikely to have a defective headed component on the upper surface of the vibration-free plate, and the balance is lost. There is also an advantage that it is easier to slide into the basket. Moreover, since the component supply apparatus of the present invention has a slope on the upper surface of the vibration-free plate, there is an advantage that the headed component is most easily slid into the basket.

It is a perspective view of the components supply apparatus which concerns on this invention. FIG. 2 is a partially cutaway cross-sectional perspective view showing a main part of FIG. 1.

  Hereinafter, a component supply apparatus according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. The component supply device 1 of the present invention includes a basket 10 that can store a large number of screws W, which is an example of a headed component, a rake plate 20 that is disposed in the basket 10 so as to be swingable in the direction indicated by an arrow A, A vibration rail 30 capable of suspending a screw W scooped up by swinging of the rake plate 20, a vibration-free plate 5 disposed on both sides of the vibration rail 30, and a screw W conveyed forward of the vibration rail 30. And a screw feeding unit 40 for receiving the screws one by one and sending them to a screwing machine (not shown).

  The basket 10 includes a cover 15 that is attached to an upper portion thereof and can be opened and closed. The basket 10 is configured so that the screw W can be appropriately replenished from an opening of the basket 10. The basket 10 is configured such that the rear end side of the vibration rail 10 is positioned therein, and the rake plate 20 is swingably arranged from the substantially horizontal bottom surfaces 13R and 13L. Furthermore, the inner peripheral surface of the basket 10 includes the bottom surface 13R (13L), a front inclined surface 11R (11L) that is inclined from the bottom surface 13R (13L) at an angle toward the front of the vibration rail 30, and the bottom surface. 13R (13L) and a side inclined surface 12R (12L) that is adjacent to the front inclined surface 11R (11L) and guides the screw W to the side of the rake plate 20 and the vibration rail 30.

  The rake plate 20 is connected to a driving source such as an air cylinder or a motor (not shown), and draws an arc as indicated by an arrow A in FIG. 2 from below to above or from above to below. It is configured to be reciprocally swingable. The rake plate 20 includes a suspension groove 20a into which the shaft portion of the screw W can be inserted and a support surface 20R (20L) capable of supporting the head of the screw W in a suspended manner. Thus, the rake plate 20 starts swinging by the operation of the drive source, scoops up the screw W in the basket 10, and reaches the swing top dead center to be supported on the support surface 20R (20L). The screw W can be slid down toward the rear end of the vibration rail 30.

  The vibration rail 30 includes a groove 30a having a slightly wider width than the suspension groove 20a, and conveying surfaces 30R and 30L extending so as to sandwich the groove 30a and extending substantially horizontally. It is arranged so as to connect the inside of the basket 10. The groove 30a and the conveying surface 30R (30L) are configured over the entire length of the vibration rail 30 and are configured to be supported by hanging the head of the screw W in the same manner as the rake plate 20. In addition, the vibration rail 30 is fixed to a vibrator 35 disposed below the vibration rail 30 and can be slightly vibrated by vibrations generated by the vibrator 35. Therefore, the vibration rail 30 can vibrate and convey the screw W suspended on the vibration rail 30 to the screw feed unit 40. The vibration rail 30 has a rear end formed in an arc shape, and is configured to guide the front surface of the rake plate 30 along the arc-shaped rear end.

  The non-vibrating plate 5 includes a plate 5 </ b> R arranged along the right side surface of the vibration rail 30 and a plate 5 </ b> L arranged along the left side surface of the vibration rail 30. The non-vibrating plate 5 is disposed separately from the vibrator 35 and the vibrating rail 30, and is configured so as not to vibrate itself. As a result, a large number of screws W stored in the basket 10 come into contact with the side surface of the vibration-free plate 5 even if the screws W are moved toward the side surface of the vibration rail 30 by the side inclined surface 12R (12L) of the basket 10. For this reason, the vibration of the vibration rail 30 is weakened as in the prior art, or it is difficult to stop the vibration. Therefore, the screw W in the normal posture suspended from the vibration rail 30 is reliably supplied to the screw feed unit 40.

  The non-vibration plate 5 is dimensioned so that the upper surface thereof is positioned lower than the conveying surface 30R (30L) of the vibration rail 30. Thereby, for example, even if the screw Wn in a poor posture lying down as shown in FIG. 2 is scooped up by the rake plate 20 and slid down on the vibration rail 30, the upper surface of the non-vibration plate 5 is transported 30R (30L). Therefore, the support surface that supports the shaft portion of the screw Wn is only the transport surface 30R (30L). Therefore, the screw Wn in an unstable posture tends to lose the balance on the vibration rail 30 and easily fall into the basket 10. That is, by making the upper surface of the non-vibrating plate 5 lower than the conveying surface 30R (30L), a space is formed in which the screw Wn in a defective posture can be easily dropped into the basket 10.

  Further, the plate 5R (5L) is set to a thickness having a dimension smaller than the width of the transport surface 30R (30L), and is configured to have a thickness equal to or less than the shaft diameter of the screw W. As a result, the screw Wn is transferred from the vibration rail 30 to the non-vibration plate 5 and hardly stays on the upper surface of the non-vibration plate 5.

  Further, each of the plates 5R (5L) is provided with an inclined surface inclined toward the forward inclined surface 12R (12L). Thereby, since the upper surface of the non-vibration plate 5 becomes a narrow area, the fall of the screw Wn into the basket 10 can be further promoted. Moreover, if the head of the screw W to be transported has an umbrella shape, the non-vibration plate 5 interferes with the head that protrudes obliquely downward in an umbrella shape even when the umbrella-shaped screw W is suspended from the vibration rail 30. hard.

  In addition, since the component supply apparatus 1 of this invention should just isolate | separate and arrange | position the said vibration-free plate 5 from the vibration rail 30, it is comprised so that it may extend in the orthogonal direction from the front inclined surface 11R (11L) of the said basket 10, for example. You may comprise as a part of basket 10. FIG. Further, the component supply device 1 of the present invention is a so-called dual component supply device including two sets of the above-described components as shown in FIG. 1, but is not limited to this, in addition, The present invention is applicable as long as the screw W is supplied to the vibration rail extending substantially horizontally from the basket and is conveyed by vibration.
