Description

[Technical field]

[0001] The present invention relates to a part supplying device that supplies rod-shaped parts, such as screw parts, to a working position of a power tool. [Background technology]

[0002] Conventionally, when supplying screw fasteners to the front of a driver bit of a screw tightening machine, a parts supplying device is known that includes a storage hopper having an inclined bottom surface portion arranged opposite to each other and a scoop plate that moves up and down in the storage hopper. In this parts supplying device, a scoop plate storage groove is formed at the bottom of the storage hopper, and the scoop plate moves back and forth in the scoop plate storage groove. Therefore, when the scoop plate rises in the scoop plate storage groove, some of the screw fasteners stored in the storage hopper are in a position along the scoop groove of the scoop plate and are scooped up by the scoop plate.

[0003] [Patent Document 1] JP 2003-192119 A Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional parts supply devices, a storage hopper made of casting is generally used. For example, when the storage hopper is made of aluminum casting, the surface of the inclined bottom of the storage hopper is relatively soft, and the surface of the inclined bottom may be damaged when the screw parts stored in the storage hopper get caught on the surface of the inclined bottom. In such a case, in order to repair the surface of the inclined bottom, it is necessary to remanufacture the entire storage hopper. Also, rod-shaped parts stored in the storage hopper may get caught on the surface of the inclined bottom and not move toward the scoop plate storage groove, so that the rod-shaped parts may remain in the storage hopper.

[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a parts supplying device that is capable of easily repairing the surface of the inclined bottom portion of a storage hopper even if the surface of the inclined bottom portion is damaged.

[0006] Another object of the present invention is to provide a part supplying device capable of preventing rod-shaped parts from remaining in a storage hopper. [Means for solving the problem]

[0007] That is, the part supplying device according to the present invention comprises a storage hopper for storing rod-shaped parts, and a scoop plate storage groove provided at the bottom of the storage hopper. The storage hopper is moved back and forth through the and a scooping plate for scooping up the rod-shaped parts in the storage hopper, , the above The hopper member has an inclined surface portion inclined toward the scoop plate storage groove, and a plate-shaped member attached to the surface of the inclined surface portion. The plate-like member is disposed so that its lower end portion is aligned with the scoop plate storage groove, and the lower end portion is pressed against the lower portion of the storage hopper and is in a bent state. It is characterized by:

[0008] As a result, in the parts supply device according to the present invention, for example, if the storage hopper is made of aluminum casting, the surface of the inclined bottom of the storage hopper is relatively soft and therefore easily damaged, but since the plate-shaped member is attached to the surface of the inclined bottom, damage to the inclined bottom of the storage hopper can be prevented. Also, even if the plate-shaped member attached to the surface of the inclined bottom is damaged, the plate-shaped member can be easily replaced.

[0009] In the component supply device according to the present invention, The above The plate-like member is characterized in that its surface roughness, in terms of ten-point average roughness Rz, is 0 to 0.200 μm.

[0010] As a result, in the part supply device according to the present invention, for example, when the storage hopper is a casting (e.g., an aluminum casting), the surface of the inclined bottom of the storage hopper is relatively soft and therefore easily damaged, but since the plate-shaped member is attached to the surface of the inclined bottom, damage to the inclined bottom of the storage hopper can be prevented. In addition, even if the plate-shaped member attached to the surface of the inclined bottom is damaged, the plate-shaped member can be easily replaced. In addition, since the inclined bottom, which slides the rod-shaped parts stored in the storage hopper toward the scoop plate storage groove, is formed into a smooth surface, the rod-shaped parts stored in the storage hopper slide appropriately toward the scoop plate storage groove. Therefore, it is possible to prevent the rod-shaped parts from remaining in the storage hopper. In addition, by attaching the plate-shaped member to the surface of the inclined bottom of the hopper member formed by casting, a storage hopper having an inclined surface formed into a smooth surface can be formed relatively inexpensively and easily.

[0011] In the component supplying device according to the present invention, the plate-like member is made of a metal member.

[0012] As a result, in the component supplying device according to the present invention, the durability of the surface of the inclined bottom portion of the storage hopper is improved.

[0013] In the component supplying device according to the present invention, the plate-like member is formed of an elastic material.

[0014] As a result, in the part supply device according to the present invention, even if a rod-shaped part gets caught between the plate-shaped member and the scoop plate when the scoop plate is lowered, the lower end of the plate-shaped member is deformed by being pressed by the rod-shaped part, thereby preventing malfunctions such as the scoop plate being unable to descend due to the rod-shaped part getting caught. Effect of the Invention

[0015] As described above, according to the present invention, it is possible to prevent the inclined bottom portion of the storage hopper from being damaged, and also to prevent rod-shaped parts from remaining in the storage hopper. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a component supplying device according to an embodiment of the present invention will be described with reference to the drawings.

[0018] (First embodiment) The part supplying device 1 of this embodiment is a part supplying device that supplies screw fasteners 2, which are rod-shaped parts (such as headed screws, etc.). As shown in Fig. 1, the part supplying device 1 has a storage hopper 3A that stores a large number of screw fasteners 2, a scoop plate 4 that moves up and down in the storage hopper 3A, and a conveying chute 5 having a guide groove 5a that guides the screw fasteners 2.

[0019] The storage hopper 3A has a space for storing the screw fasteners 2, and at its lowest part, a scoop plate storage groove 3n for allowing the scoop plate 4 to move up and down reciprocally is formed. The configuration of the storage hopper 3A will be described in detail later.

[0020] The scoop plate 4 is fan-shaped, and on its upper surface is formed a scoop groove 4a for scooping up the screw fastener 2. As described above, the scoop plate 4 is stored in the scoop plate storage groove 3n in the lower part of the storage hopper 3, and is configured to be able to reciprocate up and down within the scoop plate storage groove 3n.

[0021] Furthermore, one end of the scoop plate 4 is fixed to an arm 6 that is held so as to be freely rotatable, and a cam groove 6a is provided in the center of the arm 6. A cam follower 6b attached to a swivel lever 7 is disposed to follow the cam groove 6a, and when the swivel lever 7 is rotated by the rotation of a motor 8b via a pulley mechanism 8a, the arm 6 and the scoop plate 4 reciprocate vertically by a predetermined angle. Moreover, the scoop plate 4 is configured to guide the screw fasteners 2 into the scoop groove 4a when in the lowest position, and to communicate the scoop groove 4a with the guide groove 5a of the conveyor chute 5 when in the highest position, thereby supplying the screw fasteners 2 to the guide groove 5a.

[0022] The conveying chute 5 is configured to receive vibrations from the vibrator 9 while being inclined slightly downward toward the tip, so that the screw fasteners 2 placed on the conveying chute 5 move forward toward the tip as the conveying chute 5 vibrates. In addition, a removal blade (not shown) that reciprocates back and forth is disposed above the retracting end of the conveying chute 5, so that the screw fasteners 2 that are misaligned and placed on the conveying chute 5 are returned into the storage hopper 3.

[0023] Furthermore, a screw separating unit 10 is disposed at the leading end of the conveying chute 5, and this screw separating unit 10 has the function of separating the leading screw fastener 2 one by one. Moreover, this screw separating unit 10 is configured to feed the screw fastener 2 in a predetermined position to the tip of a driver bit (not shown) of a screw tightening machine (not shown) by air feeding.

[0024] The configuration of the storage hopper 3A will be described with reference to FIGS.

[0025] At the bottom of the storage hopper 3A, a scoop plate storage groove 3n for the scoop plate 4 to move up and down is formed as shown in Fig. 2. The scoop plate storage groove 3n is a linear groove, and its horizontal cross section has substantially the same shape as the upper surface of the scoop plate 4.

[0026] The storage hopper 3A has a hopper member 3, and two reinforcing members 30 and two plate-shaped members 31 attached to the inside of the hopper member 3.

[0027] The hopper member 3 is formed of a casting (e.g., aluminum casting) in the same manner as a conventional storage hopper. As shown in FIG. 3(a), the hopper member 3 has two inclined surface portions 3a arranged opposite each other on both sides of the scoop plate storage groove 3n, and side surface portions 3b located on both sides and extending in a direction intersecting the two inclined surface portions 3a. The lower end of the inclined surface portion 3a is connected by a vertical surface portion 3t extending vertically to a horizontal surface portion 3c formed on the edge of the scoop plate storage groove 3n. The side surface portions 3b are located opposite each other, and the lower portions of each are inclined inward as they go downward.

[0028] The reinforcing member 30 is, for example, a rectangular parallelepiped member made of stainless steel, as shown in FIG. 3(b). The reinforcing member 30 is attached to the horizontal surface portion 3c of the hopper member 3, as shown in FIG. 4. The horizontal cross section of the reinforcing member 30 has substantially the same shape as the horizontal cross section of the horizontal surface portion 3c, and the vertical height of the reinforcing member 30 is substantially the same as the vertical height of the vertical surface portion 3t. Therefore, the upper surface of the reinforcing member 30 extends horizontally from the lower end of the inclined surface portion 3a. Thus, in this embodiment, since the hopper member 3 is made of aluminum casting and is relatively soft, the edge of the scoop plate storage groove 3n is reinforced by the reinforcing member 30 so that the edge of the scoop plate storage groove 3n does not deform when it comes into contact with the scoop plate 4.

[0029] The plate-like member 31 is, for example, a stainless steel plate-like member (e.g., 1.2 mm thick) and is smaller than the inclined surface portion 3a of the hopper member 3 as shown in FIG. 3(b). The plate-like member 31 has a shape that fits the surface of the inclined surface portion 3a of the hopper member 3 and is attached to the upper surface of the inclined surface portion 3a of the hopper member 3. The plate-like member 31 is fastened by a mounting screw T in a state where the three hole portions 31a1 are aligned with the positions of three screw holes 3a1 formed in the inclined surface portion 3a of the hopper member 3. The lower end portion 31a of the plate-like member 31 is formed in a straight line and is attached so that the lower end portion 31a fits along the scoop plate storage groove 3n as shown in FIG. 2.

[0030] FIG. 4(a) shows the scoop plate 4 in its lowermost position, and FIG. 4(b) shows the scoop plate 4 in its uppermost position.

[0031] When the plate-shaped member 31 is attached to the inclined surface portion 3a of the hopper member 3 by the mounting screw T, the lower end portion 31a of the plate-shaped member 31 is pressed downward against the upper surface of the reinforcing member 30, as shown in Fig. 4. Therefore, the vicinity of the lower end portion 31a of the plate-shaped member 31 is bent upward. At that time, the lower end portion 31a of the plate-shaped member 31 is disposed above the edge of the scoop plate storage groove 3n and approximately parallel to the edge of the scoop plate storage groove 3n.

[0032] Furthermore, when the plate-shaped member 31 is attached in the appropriate position relative to the surface of the inclined surface portion 3a of the hopper member 3, the scoop plate 4 moves in the vertical direction with a very small gap formed between the side of the scoop plate 4 and the lower end portion 31a of the plate-shaped member 31.

[0033] The screw fasteners 2 stored in the storage hopper 3A slide down the surface of the plate-shaped member 31 toward the scoop plate storage groove 3n. That is, the surface of the plate-shaped member 31 forms an inclined bottom surface 3Aa that allows the screw fasteners 2 stored in the storage hopper 3A to slide down toward the scoop plate storage groove 3n. The surface of the plate-shaped member 31 that forms the inclined bottom surface 3Aa is formed into a smooth surface by, for example, buffing with #400. Specifically, the surface roughness of the plate-shaped member 31 is 0 to 0.200 μm in ten-point mean roughness Rz, and preferably 0 to 0.150 μm in ten-point mean roughness Rz.

[0034] As described above, the part supplying device 1 of this embodiment includes a storage hopper 3A that stores the screw fasteners 2, and a scoop plate 4 that moves back and forth within a scoop plate storage groove 3n provided at the bottom of the storage hopper 3 to scoop up the screw fasteners 2 in the storage hopper 3A. The storage hopper 3A includes a hopper member 3 formed by casting and having an inclined surface portion 3a that inclines toward the scoop plate storage groove 3n, and a plate-shaped member 31 attached to the surface of the inclined surface portion 3a.

[0035] As a result, in the part supplying device 1 according to this embodiment, when the hopper member 3 is an aluminum casting, the surface of the inclined surface portion 3a of the hopper member 3 is relatively soft and therefore easily damaged, but since the plate-like member 31 is attached to the surface of the inclined surface portion 3a, damage to the inclined bottom surface portion 3Aa of the storage hopper 3A can be prevented. Also, even if the plate-like member 31 attached to the surface of the inclined bottom surface portion 3Aa is damaged, the plate-like member 31 can be easily replaced.

[0036] In addition, the part supplying device 1 of this embodiment includes a storage hopper 3A that stores the screw fasteners 2, and a scoop plate 4 that moves back and forth within a scoop plate storage groove 3n provided at the bottom of the storage hopper 3 to scoop up the screw fasteners 2 in the storage hopper 3A. The storage hopper 3A includes a hopper member 3 formed of casting and having an inclined surface portion 3a that inclines toward the scoop plate storage groove 3n, and a plate-shaped member 31 attached to the surface of the inclined surface portion 3a, and the surface roughness of the plate-shaped member 31 is 0 to 0.200 μm in ten-point average roughness Rz.

[0037] As a result, in the part supplying device 1 of this embodiment, when the hopper member 3 is an aluminum casting, the surface of the inclined surface portion 3a of the hopper member 3 is relatively soft and easily damaged, but since the plate-shaped member 31 is attached to the surface of the inclined surface portion 3a, damage to the inclined bottom surface portion 3Aa of the storage hopper 3A can be prevented. Even if the plate-shaped member 31 attached to the surface of the inclined bottom surface portion 3Aa is damaged, the plate-shaped member 31 can be easily replaced. Furthermore, since the inclined bottom surface portion 3Aa that slides the screw fasteners 2 stored in the storage hopper 3A toward the scoop plate storage groove 3n is formed into a smooth surface, the screw fasteners 2 stored in the storage hopper 3A slide appropriately toward the scoop plate storage groove 3n. Therefore, it is possible to prevent the screw fasteners 2 from remaining in the storage hopper 3A. Furthermore, by attaching a plate-shaped member 31 to the surface of the inclined surface portion 3a of the hopper member 3 formed by casting, a storage hopper 3A having an inclined bottom surface portion 3Aa formed into a smooth surface can be formed relatively cheaply and easily.

[0038] In the component supplying device 1 of the present embodiment, the plate-like member 31 is made of a metal material.

[0039] As a result, in the component supplying device 1 of this embodiment, the durability of the surface of the inclined bottom portion 3Aa of the storage hopper 3A is improved.

[0040] Second embodiment The component supplying device 101 of this embodiment differs from the component supplying device 1 of the first embodiment in that the plate-shaped member 31 in the first embodiment is made of a metal member, whereas the plate-shaped member 131 in this embodiment is made of an elastic member. Note that detailed description of the same configuration of the component supplying device 101 of this embodiment as that of the component supplying device 1 of the first embodiment will be omitted.

[0041] As described above, in the part supplying device 1 of the first embodiment, when the plate-shaped member 31 is attached at an appropriate position on the inclined surface portion 3a of the hopper member 3, the scoop plate 4 moves up and down in a state where the gap formed between the side surface of the scoop plate 4 and the lower end portion 31a of the plate-shaped member 31 is very small. Therefore, the screw fasteners 2 stored in the storage hopper 3A do not move between the scoop plate 4 and the plate-shaped member 31.

[0042] However, when the component supplying device 1 is continuously used, the plate-shaped member 31 may shift from the appropriate position. Fig. 5(a) illustrates a state in which, for example, the right-side plate-shaped member 31 shifts from the appropriate position in a direction away from the scoop plate storage groove 3n. In this state, the lower end 31a of the plate-shaped member 31 is disposed to the right of the vertically upper right edge of the scoop plate storage groove 3n. Therefore, the scoop plate 4 moves in the vertical direction with a large gap formed between the side surface of the scoop plate 4 and the lower end 31a of the plate-shaped member 31.

[0043] In this manner, when the scoop plate 4 descends in a state where the gap formed between the side surface of the scoop plate 4 and the lower end 31a of the plate-shaped member 31 is large, the screw fastener 2 in contact with the scoop plate 4 tries to move downward, but cannot move due to being caught on the lower end 31a of the plate-shaped member 31 or the weight of the screw fastener 2 above, and the screw fastener 2A is caught between the scoop plate 4 and the lower end 31a of the plate-shaped member 31 as shown in FIG. 5(b). Then, the caught screw fastener 2A acts like a wedge and presses the scoop plate 4 and the plate-shaped member 31 in the opposite direction. Then, the scoop plate 4 pressed by the caught screw fastener 2A is pressed toward the reinforcing member 30 located on the opposite side to the gap into which the screw fastener 2A is caught and the edge of the scoop plate storage groove 3n of the hopper member 3. Therefore, friction between the scoop plate 4 and the reinforcing member 30 or between the scoop plate 4 and the hopper member 3 increases significantly, making it impossible for the scoop plate 4 to move up and down, and causing the component supplying device 1 to abnormally stop.

[0044] In order to solve the above problem, in the component supplying device 101 of this embodiment, the plate-like member 131 is made of an elastic member.

[0045] The plate-like member 131 is, for example, a plate-like member (e.g., 1 mm thick) made of Teflon (registered trademark), and is smaller than the inclined surface portion 3a of the hopper member 3. As shown in FIG. 6, the plate-like member 131 has a shape that fits the surface of the inclined surface portion 3a of the hopper member 3, and is attached to the upper surface of the inclined surface portion 3a of the hopper member 3. As with the plate-like member 31 of the first embodiment, the plate-like member 131 is fastened by a mounting screw T in a state where three hole portions (not shown) are aligned with the positions of three screw holes 3a1 formed in the inclined bottom surface portion 3a of the hopper member 3. The lower end portion 31a of the plate-like member 31 is formed in a straight line, and is attached so that the lower end portion 31a fits along the scoop plate storage groove 3n.

[0046] When the plate-shaped member 131 is attached to the inclined surface portion 3a of the hopper member 3 by the attachment screw T, the lower end portion 131a of the plate-shaped member 131 is pressed downward against the upper surface of the reinforcing member 30. Therefore, the vicinity of the lower end portion 131a of the plate-shaped member 131 is bent upward. At that time, the lower end portion 131a of the plate-shaped member 131 is disposed above the edge of the scoop plate storage groove 3n and approximately parallel to the edge of the scoop plate storage groove 3n.

[0047] Furthermore, when the plate-shaped member 131 is attached in an appropriate position relative to the surface of the inclined surface portion 3a of the hopper member 3, the scoop plate 4 moves in the vertical direction with a very small gap formed between the side of the scoop plate 4 and the lower end portion 131a of the plate-shaped member 131, as in the first embodiment.

[0048] The screw fasteners 2 stored in the storage hopper 3A slide down the surface of the plate-shaped member 131 toward the scoop plate storage groove 3n. That is, the surface of the plate-shaped member 131 becomes the inclined bottom surface portion 103Aa that allows the screw fasteners 2 stored in the storage hopper 103A to slide down toward the scoop plate storage groove 3n. The surface of the plate-shaped member 131 that becomes the inclined bottom surface portion 103Aa is formed into a smooth surface. Specifically, the surface roughness of the plate-shaped member 131 is 0 to 0.200 μm in ten-point average roughness Rz.

[0049] In the component supply device 101 of this embodiment, similarly to the component supply device 1 of the first embodiment, when the component supply device 101 is continuously used, the plate-shaped member 131 may shift from the appropriate position in a direction away from the scoop plate storage groove 3n. FIG. 7(a) illustrates a state in which, for example, the right-side plate-shaped member 131 is shifted from the appropriate position. In this state, the lower end portion 131a of the plate-shaped member 131 is disposed to the right of the right side of the edge of the scoop plate storage groove 3n vertically above. Therefore, the scoop plate 4 moves in the vertical direction in a state in which the gap formed between the side surface of the scoop plate 4 and the lower end portion 131a of the plate-shaped member 131 is large.

[0050] In this way, when the scoop plate 4 descends with a large gap formed between the side surface of the scoop plate 4 and the lower end 131a of the plate-shaped member 131, the screw fastener 2 in contact with the scoop plate 4 attempts to move downward, but is unable to move due to being caught on the lower end 131a of the plate-shaped member 131 or the weight of the screw fastener 2 above, and as shown in Fig. 7(b), the screw fastener 2A becomes caught between the scoop plate 4 and the lower end 131a of the plate-shaped member 131. Then, the caught screw fastener 2A acts like a wedge and pushes the scoop plate 4 and the plate-shaped member 131 in opposite directions. However, since the plate-like member 131 is made of an elastic material and the vicinity of the lower end 131a of the plate-like member 131 can be deformed in a direction away from the scoop plate 4, even if the scoop plate 4 is stretched by the caught screw fastener 2A, it is not pressed with a large force toward the reinforcing member 30 located on the opposite side to the gap into which the screw fastener 2A is caught or the edge of the scoop plate storage groove 3n of the hopper member 3. Therefore, even if the screw fastener 2 is caught between the lower end 131a of the plate-like member 131 and the side surface of the scoop plate 4, the friction between the scoop plate 4 and the reinforcing member 30 or the hopper member 3 does not increase significantly. Therefore, it is possible to prevent the scoop plate 4 from becoming unable to move up and down, and it is possible to prevent the component supply device 101 from abnormally stopping.

[0051] In the component supplying device 101 of this embodiment, the same effects as those of the first embodiment can be obtained.

[0052] In the component supplying device 101 of this embodiment, the plate-like member 131 is an elastic member.

[0053] As a result, in the part supplying device 101 of this embodiment, even if the screw fastener 2 gets caught between the plate-shaped member 131 and the scoop plate 4 when the scoop plate 4 descends, the lower end portion 131a of the plate-shaped member 131 is deformed by being pressed by the screw fastener 2. Therefore, it is possible to prevent malfunctions such as the scoop plate 4 being unable to descend due to the screw 2 getting caught.

[0054] Although the embodiment of the present invention has been described above, the configuration of the embodiment is not limited to the above, and various modifications are possible.

[0055] For example, in the first embodiment, the plate-shaped member 31 is formed of a stainless steel member, and in the second embodiment, the plate-shaped member 131 is formed of a Teflon (registered trademark) member, but in the present invention, the material, shape, and thickness of the plate-shaped member are arbitrary. In the first embodiment, the plate-shaped member 31 may be formed of a metal member. For example, the plate-shaped member 31 may be made of copper or the like other than stainless steel. In addition, although the case where the surface of the plate-shaped member 31 is formed into a smooth surface by buffing with #400 has been described, the method of polishing the surface of the plate-shaped member 31 is arbitrary. In the second embodiment, the plate-shaped member 131 may be formed of a member having elasticity. For example, the plate-shaped member 131 may be made of high-density polyethylene or the like other than Teflon (registered trademark). In the first and second embodiments, the hopper member 3 is formed of an aluminum casting, and the reinforcing member 30 is formed of a stainless steel member, but in the present invention, the material of the hopper member formed of casting and the material of the reinforcing member 30 are arbitrary.
