Japanese Unexamined Patent Publication No. 2008-114186

In the technique described in the above patent document, a portion for taking out bolts having a large head size one by one and a portion for taking out bolts having a small head size one by one are formed from the tip end portion of the transport rail. With such a structure, it is impossible for an operator to align a predetermined number of bolts in a predetermined direction and take them out at one time.

The present invention has been provided to solve the above-mentioned problems, and is a component taking-out structure portion capable of easily grasping a plurality of axial parts in a predetermined number in a predetermined direction. For the purpose of providing.

The invention according to claim 1
A plurality of shaft-shaped parts having at least a head and a shaft are targeted for extraction.
The guide member that conveys the shaft-shaped parts that have been conveyed from the parts supply source such as the parts storage container of the parts feeder and the straight-ahead feeder is arranged so as to be inclined so that the tip side is low and protrudes into the space.
The guide member is formed by arranging two elongated rail members whose upper surface is a sliding surface in parallel.
The lower surface of the head slides on the sliding surface, and the shaft portion passes through the passage space between the two rail members in a suspended state so that the shaft portion can swing along the longitudinal direction of the guide member. Configure to
The length of the shaft portion protruding below the rail member is defined as a length that allows the operator to manually grasp the plurality of protruding shaft portions from below.
A braking means for stopping the earliest shaft-shaped part when viewed in the transport direction of the shaft-shaped part is provided on the rail member.
The structure of the braking means is formed so that the shaft portion can pass through the braking means in a state where the shaft portion can swing along the longitudinal direction of the guide member.
The braking force of the braking means is a component taking-out structure portion having a value that can be pulled out from the guide member while the operator holds the shaft portion.

The guide member is arranged so as to protrude into the space, and when the shaft-shaped part is transferred in a suspended state, the first shaft-shaped part is stopped by the braking means, and the subsequent shaft-shaped part is stopped. Align with the guide member. The lower side of the shaft-shaped part protrudes from the guide member, and when a plurality of predetermined shaft-shaped parts are grasped by hand from the lower side and pulled out toward the tip of the guide member while being held, this pulling force is applied to the braking means. It exceeds the braking force and passes through the braking means. By this passage, a plurality of shaft-shaped parts are held in the same direction in a hand-held state. That is, since the shaft portion is grasped, the heads are in a state of being lined up on the upper side.

Since the shaft part of the shaft-shaped part protrudes from the rail member so that it can be easily grasped, a predetermined number of shaft-shaped parts can be grasped by hand from the lower side and pulled out from the guide member all at once with a simple operation. Parts can be taken out. By grasping the shaft from the lower side, the head is grasped by the upper side. Therefore, it is possible to pinch the head with the other hand and insert it into a target place such as a screw hole, which is effective for improving workability. If the orientation of the shaft-shaped parts that are grasped by hand is various, when picking the head with the other hand, it will be caught when checking the position of the head or pulling out the shaft-shaped parts, and it will take time and effort, shortening the work time. It is disadvantageous in terms of annoyance.

Since the braking force of the braking means is set to a value that can be pulled out from the guide member while the operator holds the shaft portion, the work can be performed with a small force when pulling out the parts, and easy work is realized.

Since the guide member protrudes into the space, this protruding part can be placed near the operator or arranged so as not to interfere with neighboring members, and an easy-to-use parts extraction structure part is provided. Be done.

Since the guide member has an elongated shape, it is possible to transfer axial parts from the parts storage container of the parts feeder or the straight feeder to the guide member, and a wide range of parts supply sources such as the parts storage container of the parts feeder and the straight feeder. It is possible to obtain a highly versatile component take-out structure.

It is a side view of a structural part and a sectional view of each part. It is a top view and a side view which show the example of a component supply source. It is a plan view and a side view in the case of a parts feeder. It is a top view of the other braking means. It is a perspective view which shows the grasped state in a plane.

Next, a mode for carrying out the component extraction structure according to the present invention will be described.

1 to 5 show examples of the present invention.

First, the shaft-shaped parts will be described.

As shown in FIG. 1 (B), the shaft-shaped component 1 is a bolt having at least a head portion 2 and a shaft portion 3, and a reference numeral 1 is also attached to this bolt. The head portion 2 is composed of a hexagonal hexagonal portion 2a and a flange portion 2b integral with the hexagonal portion 2a. The dimensions of each portion are 6 mm and 58 mm in diameter and length of the shaft portion 3, 13 mm and 1.2 mm in diameter and thickness of the flange portion 2b, respectively, and 10 mm in the major axis between the corner portions of the hexagonal portion 2a.

Next, the guide member will be described.

As shown in FIGS. 1 (A), 2 (A), (C), and 3, the elongated guide member 4 is arranged so as to protrude into the space, and the bolt 1 is pulled out from the tip thereof. It has become like. In the guide member 4, two elongated rail members 5 are arranged in parallel, and the width of the passage space 11 between the two rail members 4 is slightly larger than the diameter of the shaft portion 3, and here. It is set to 8 mm. The passage space 11 is open to the space at the tip of the guide member 4. The upper surface of both rail members 5 is a sliding surface 6, and the lower surface of the flange portion 2b slides. Therefore, as shown in FIG. 1B, the bolt 1 is in a hanging (hanging) state.

The guide member 4 is connected to the straight feeder 22, which is a component supply source described later, with a slight gap left. Then, as shown in FIG. 1 (C), the rail member 5 is joined to the inside of the support member 8 having the two columns 7 by welding or bolting, and the lower part of the support member 8 is the machine of the device. It is fixed to a stationary member 9 such as a frame. The straight-ahead feeder is indicated by reference numeral 22.

The guide member 4 is arranged in an inclined posture so that the tip side is lowered, and the lower surface of the flange portion 2b slides on the sliding surface 6 of the rail member 5 and slides down to the lower side.

Next, the braking means will be described.

The braking means 13 prevents the bolt 1 from falling off from the tip of the guide member 4 by a sliding force, and enables the bolt 1 grasped by the operator to be taken out from the guide member 4 with a small pulling force. Is. As the mode of the braking means 13, various means such as those for imparting frictional resistance by a leaf spring to the shaft portion 3 and those for applying the attractive force of a magnet can be adopted. Here, it is an example of an openable gate plate.

As shown in FIG. 1 (E), a fixing plate 14 is connected to the lateral side surface of one rail member 5 by bolting or welding, and the shaft 15 is integrated with the fixing plate in the vertical direction. A gate plate 16 is attached to the shaft 15 in a rotatable state. That is, the fixing plate 14 and the gate plate 16 are integrated in a swingable state via the shaft 15 and have the same structure as a hinge or a hinge generally adopted.

The gate plate 16 hits the end surface of the rail member 5 and stands still, and can be easily opened by the pulling force of the operator. For that purpose, a torsion coil spring 17 as defined by the JIS standard is assembled to the shaft 15, and while the spring wire 17a protruding from the coil-shaped portion is pressed against the fixing plate 14, it protrudes from the coil-shaped portion. The other spring wire 17b is pressed against the gate plate 16, and the torsional elasticity of the torsion coil spring 17 acts in the closing direction of the gate plate 16. This force in the closing direction, that is, the braking force, prevents the bolt 1 from falling from the tip of the guide member 4 without permission due to the downward inclination of the guide member 4, and when the operator grabs and pulls out the bolt 1, a small drawer is used. It is set so that it can be done by force.

Next, the hand grip of the worker will be described.

When the downward inclination of the guide member 4 is as shown in the drawing, the suspended bolt 1 slides down in a posture close to the vertical direction. The shaft portion 3 is in a state of protruding from the rail member 5 so that the operator can grasp the plurality of bolts 1 from the lower side. Since the protruding length here is 45 mm, the vertical dimension of the rail member 5 is 13 mm. The reason why the flange portion 2b is close to the vertical direction is that the subsequent flange portion 2b overlaps the preceding flange portion 2b.

Next, the hand grip portion will be described.

The hand-held portion means a portion of the shaft portion 3 protruding downward from the rail member 5, is indicated by reference numeral 18, and has a protruding length of 45 mm. As is clear from FIG. 1 (A), the shaft portions 3 protruding downward are in a state of being lined up in a substantially row, and among them, the five shaft portions 3 are arranged from the lower side at the discretion of the operator. Grasp it by hand and pull it out as it is in the longitudinal direction of the guide member 4, that is, in the direction of the gate plate 16 (direction of arrow 30 in FIG. 1A). At this time, since the pulling force of the operator exceeds the closing force of the gate plate 16 by the torsion coil spring 17, the five gripped bolts 1 are pulled out from the guide member 4 all at once. The open state of the gate plate 16 at this time is shown by a two-dot chain line in FIG. 1 (D).

The spring force of the torsion coil spring 17 is set to a value that enables the pull-out operation as described above, that is, a value that allows the operator to pull out from the guide member 4 while grasping the shaft portion 3.

Since the operator grabs the hand grip portion 18 from the lower side, the five bolts 1 pulled out from the guide member 4 are in a grasped state, and the shaft portion 3 is hidden in the hand as shown in FIG. , The head 2 is exposed in a state where it is almost aligned. In the case of the figure, as shown in FIG. 5, the bolt 1 is being held by the left hand, and the head 2 is picked up by the right hand and inserted into a screw hole or the like.

Next, the parts supply source will be described.

There are various sources of parts such as parts storage containers for parts feeders, straight-ahead feeders, and parts cutting units. Here, a straight-ahead feeder is illustrated.

In the component supply device 100 shown in FIG. 2, the bolt 1, which is a shaft-shaped component, is transferred from the component storage box 21 composed of the square wall plate 19 and the bottom plate 20 when viewed from above to the linear feeder 22, and then the guide. Transfer to member 4.

As shown in FIG. 2C, the straight-ahead feeder 22 has a hanging member 24 connected to a receiving member 23 of an elongated component. As will be described later, the bolt 1 transferred to the receiving member 23 is transferred to the hanging member 24 by vibration transfer, where it is suspended and sent to the guide member 4. The suspension member 24 has the same structure as the guide member 4 described above, and is a method in which the lower surface of the flange portion 2b is slid on the sliding surfaces of a pair of parallel rail members.

The receiving member 23 and the hanging member 24 are coupled to the elongated base member 25 via the supporting members 26 and 27. The base member 25 is arranged above the stationary member 9 by two leaf springs 28 arranged diagonally, and is fed to the left in FIG. 2 by applying vertical vibration to the base member 25 by an electromagnet 29. The output component is formed and bolted.

A lift member 31 is arranged at a corner portion of the storage box 21. The lift member 31 has a mounting surface 32 whose upper surface is inclined, and is moved up and down by an air cylinder 33. When the mounting surface 32 is at the lowest position indicated by the alternate long and short dash line, the bolt 1 is transferred onto the mounting surface 32, and when the mounting surface 32 reaches the highest position shown by the solid line, the bolt 1 is transferred onto the receiving member 23. To. The receiving member 23 is formed with a recess 34 for preventing the bolt 1 from falling.

Various methods such as a lift member 31 and a bucket conveyor are adopted as a method for transferring parts to the straight-ahead feeder 22. The bolt 1 sent from the straight feeder 22 which is the component supply source is transferred to the guide member 4. From such a transport flow of the bolt 1, the straight feeder 22 is positioned as a component supply source.

Although the guide member 4 described above has a downward slope, it is also possible to arrange the guide member 4 in the horizontal direction. In this case, as shown in FIG. 2D, the guide member 4 is integrally formed with the hanging member 24 of the straight feeder 22, and is conveyed by the transmission vibration of the straight feeder 22.

Next, other parts supply sources will be described.

As shown in FIG. 3, a parts feeder 36 having a circular vibrating bowl 35 is a parts supply source. The guide member 4 is connected to the delivery pipe 37 extending from the bowl 35 with a slight gap.

The bolt 1 transferred to the delivery pipe 37 by the delivery vibration is transferred to the guide member 4 in a suspended state. From such a transport flow of the bolt 1, the bowl 35, which is a storage container for the parts feeder 36, is positioned as a parts supply source.

Next, other braking means will be described.

As shown in FIG. 4, a permanent magnet 38 is embedded near the tip of the rail member 5 on one side, and the shaft portion 3 is attracted to the inner surface of the rail member 5. By this suction, a braking force acts on the first bolt 1, and the subsequent bolts 1 are aligned in the guide member 4. When the attractive force of the permanent magnet 38 is insufficient, it is possible to increase the number of permanent magnets 38 for the first bolt 1 or to add the permanent magnet 38 for the second bolt 1.

At the discretion of the operator, the five shaft portions 3 are grasped by hand from below and pulled out as they are in the longitudinal direction of the guide member 4, that is, in the direction of the permanent magnet 38. At this time, since the pulling force of the operator exceeds the attractive force of the permanent magnet 38, the five gripped bolts 1 are pulled out from the guide member 4 all at once. Attraction force of the permanent magnet 38, a value such as as possible out above such withdrawal operation, i.e., the operator is the value that can be drawn from the guide member 4 in a state of gripping the shaft portion 3.

In addition, instead of the above air cylinder, an electric motor that outputs forward and backward can be adopted. It is also possible to replace the permanent magnet with an electromagnet.

The parts feeder is of a type that vibrates a bowl, but a type that attracts parts to a rotating plate with a magnet and sends them out from a delivery pipe may be adopted. That is, it is possible to assemble a magnet on an upright rotary disk and guide the parts attracted by the rotation of the disk to the delivery passage.

The effects of the examples described above are as follows.

The guide member 4 is arranged so as to protrude into the space, and when the shaft-shaped part 1 is transferred in a suspended state, the first shaft-shaped part 1 is a gate plate 16 or a permanent magnet which is a braking means. 38 is stopped, and the shaft-shaped component 1 following it is aligned with the guide member 4. The lower side of the shaft-shaped part 1 protrudes from the guide member 4, and when a plurality of predetermined shaft-shaped parts 1 are grasped by hand from the lower side and pulled out toward the tip of the guide member 4 while being held, this pulling force is obtained. Exceeds the braking force of the braking means 16 and 38 and passes through the braking means. By this passage, the plurality of shaft-shaped parts 1 are held in the same direction in a hand-held state. That is, since the shaft portion 3 is gripped, the head portion 2 is in a state of being lined up on the upper side.

Since the shaft portion 3 of the shaft-shaped component 1 protrudes from the rail member 5 so as to be easily gripped, a predetermined number of shaft-shaped parts 1 can be grasped by hand from below and pulled out from the guide member 4 all at once. , Parts can be taken out with a simple operation. By gripping the shaft portion 3 from the lower side, the head portion 2 is gripped by the upper side. Therefore, it is possible to pinch the head 2 with the other hand and insert it into a target location such as a screw hole, which is effective for improving workability. If the orientation of the shaft-shaped part 1 grasped by hand is various, when the head 2 is picked up by the other hand, the position of the head 2 is confirmed or the shaft-shaped part 1 is pulled out. It is disadvantageous in terms of time saving and annoyance.

Since the braking force of the braking means 16 and 38 is set to a value that can be pulled out from the guide member 4 while the operator holds the shaft portion 3, the work can be performed with a small force when pulling out the parts, and the work is easy. Realize.

Since the guide member 4 protrudes into the space, the protrusion can be arranged near the operator or so as not to interfere with neighboring members, and an easy-to-use component extraction structure can be provided. Be done.

Since the guide member 4 has an elongated shape, the shaft-shaped component 1 from the straight-moving feeder 22 of the parts supply device 100, the delivery pipe 37 of the parts feeder 36, and the like can be transferred to the guide member 4, and the parts feeder can be transferred. The parts storage container and the straight-ahead feeder can be used as a wide range of parts supply sources, and a highly versatile parts take-out structure can be obtained.

As described above, according to the component take-out structure portion of the present invention, it is possible to easily grasp a predetermined number of a plurality of axial parts by aligning them in a predetermined direction. Therefore, it can be used in a wide range of industrial fields such as an automobile body assembly process and a sheet metal assembly process for home electric appliances.
