Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a device for taking out a component such as an IC chip housed in a cylindrical container.

[Conventional technology]

Generally, the IC chip is stored in a cylindrical container, a so-called stick, at the time of purchase. Therefore, it is necessary to take out the IC chip from the cylindrical container when using it, but in that case, even if the IC chip slides out by tilting the stick, it does not come out because of being caught in the cylindrical container. However, it was inconvenient. Also, as an alternative method, there is a method in which a long rod attached to the tip of the piston rod of the air cylinder is inserted into the cylindrical container and the IC chip inside is pushed out at once. Since only the rod is attached to the tip of the piston rod, the length of the device becomes the length of the container plus the length of the cylinder plus the length of the rod, making the entire device very long. Yet another way is
A support is fixed on a chain or belt stretched by a pulley driven by a motor, and a rod corresponding to the length of the container is projected from this support along the moving direction of the belt.
The tip of this rod was guided by a fixed guide, inserted into the container, and the IC chip was pushed out little by little. In this case, since the length of the device is equal to the length of the container plus the length of the rod, and the height of the device is mounted on the chain or belt, the device becomes large and a large occupied space is required.

[Problems to be solved by the device]

Therefore, it is an object of the present invention to downsize the device for taking out the parts in the container so as to effectively use the space in the factory.

[Means for Solving the Problems]

In order to achieve the above object, according to the present invention, a flexible rod for extruding a component from a cylindrical container, a main roller around which the flexible rod is hung, a flexible rod and a main roller are provided. A belt that is stretched between a plurality of rollers and presses the flexible rod between the main roller and the main roller to prevent relative slippage between the flexible rod and And a motor connected to at least one of the main rollers or a plurality of rollers for driving the flexible rod so as to feed the container into or out of the container. It should be provided.

〔Example〕

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows the basic structure of the present invention in a schematic view in principle. Reference numeral 1 denotes a cylindrical container called a stick in which a component 2 such as an IC chip is housed, which is horizontally arranged on an appropriate base 3 and fixed. According to the device 10 for taking out parts in a container according to the present invention, the flexible rod 11 for inserting the part 2 into the cylindrical container 1 and pushing out the part 2 is 180 ° around the main roller 12 for driving the part. After being wound, it is guided by the lower guide means 13 so as to extend horizontally. The upper flexible rod 11 has its movement direction regulated by the guide means 14 so that it can be inserted into the cylindrical container 1. Further, a pinch roller 15 is arranged above the main roller 12,
This pinch roller presses the flexible rod 11 between itself and the main roller 12 and generates a frictional force between them to drive the main roller 12 so as not to slip. The pinch roller 15 is preferably biased toward the main roller 12 by a spring.

In operation, when the main roller 12 is rotated counterclockwise, the flexible rod 11 enters the tubular container 1 and the component 2 can be pushed out of the container 1. Once the flexible rod 11 enters the cylindrical container 1, the flexible rod 11 is guided by the wall inside the cylindrical container, so that there is no problem even if it bends. After the extrusion, the flexible rod 11 can be retracted from the cylindrical container 1 by rotating the main roller 12 in the clockwise direction.

As the flexible rod 11, for example, those shown in FIGS. 2 (a) to 2 (f) can be used. (a) is a thin highly elastic strip, (b)
Is a thin high-elasticity strip with an arcuate curved cross section as used in a metal tape measure, (c) is a line with a thin circular cross-section with high elasticity,
(d) is a highly elastic elliptical section line, (e) is a coil spring closely wound on a rectangular section, and (f) is a coil spring closely wound on a circular section.

Next, FIGS. 3 to 5 show the structure of the device which is the basis of the present invention.

In the component take-out device 20 in this cylindrical container, the base 2
Pinch rollers 24 and 25 are arranged around a main roller 23, which is integral with a shaft rotatably supported by a frame 22 fixed to the frame 1, at a top and side intervals of 90 °. These pinch rollers 24 and 25 are rotatably attached to both ends of a holder 27 which can swing around a pin 26. The pin 26 is further mounted on a support 28, the lower part of which is pinned by a pin 32 to a bifurcated member 31 fixed to a bracket 30 via guide means 29 for the rear end of the flexible rod 11. It is rotatably attached. Further, the holder 27, and hence the pinch roller, is fixed by brackets 33, 33 'mounted on both sides of the front wall 22a of the frame 22 and two tension springs 34, 34' respectively stretched at both ends of the pin 26 of the holder 27. 24 and 25 are urged toward the main roller 34. On the upper surface of the bracket 33, front guide means 35 for restricting the movement direction of the flexible rod 11 is provided. The guide means 29, 35 preferably consist of a lower part having a recess through which the flexible rod 11 passes and an upper part covering this. At the front and rear ends of the flexible rod 11, pieces 36 and 36 'that serve as stoppers are attached so as to prevent the flexible rod 11 from slipping out. Of these, the piece 36 at the front end is a component from a tubular container. Cylindrical container 1 when pushing out
It abuts the part 2 inside. Further, a sleeve 37 for housing up to the rear end of the flexible rod 11 is attached to the base 21. Also, when retracting the flexible rod 11,
A sensor 38 is attached to the bracket 33 in order to detect the front end thereof and stop the driving of the main roller 23. The sensor 38 is attached to the bracket 33 so as to be rotatable back and forth about an axis 39. (Third
Figure) acted on. This arm 40 is always a spring 4
It is urged to the side opposite to the sensor 38 by 1. Similarly, when the flexible rod 11 is paid out, the sensor 42 attached to the bracket 30 and the axis line of the bracket 30 for detecting the rear end of the flexible rod 11 and stopping the main roller 23. An arm 44 is attached so as to be vertically rotatable about 43. Similarly, the arm 44 is also biased by the spring 45 toward the side opposite to the sensor 42.
The main roller 23 is supported on the frame 22 by bearings and is connected to the shaft 47 of the motor 46. Further, the surface of the main roller 23 is preferably covered with a material 23a having a large coefficient of friction such as rubber or an uneven surface in order to increase friction with the flexible rod 11.

The operation of this device will be briefly described. From the state shown in FIG. 3, the main roller 23 is rotated clockwise to insert the flexible rod 11 into the cylindrical container 1, and the piece 36 at the front end of the flexible rod 11 is inserted into the part 2.
Is extruded from the cylindrical container 1. Finally, the piece 36 ′ at the rear end of the flexible rod 11 pushes the arm 43 to actuate the sensor 41, whereby the motor 46 stops and the main roller 23 stops. Next, the motor 46 is rotated in the reverse direction so that the main roller 23
Is rotated counterclockwise to retract the flexible rod 11 from the cylindrical container 1. Finally, the piece 36 at the front end of the flexible rod 11
Pushes the arm 40 to actuate the sensor 38 to drive the motor 4

FIG. 6 shows a device for taking out parts in a cylindrical container according to the present invention. Instead of a pinch roller, a flexible belt is pressed and held between the main roller and a tensioned belt so as to obtain a large frictional force which cannot be obtained by the pinch roller. A belt 55 is stretched around three rollers 52, 53, 54 arranged around the main roller 51. The belt 55 contacts the flexible rod 11 over a contact angle θ and presses it against the main roller 51. ing. Main roller 51,
Any one of the rollers 52 and 54 is used as a drive roller. The rotation centers of the main roller 51 and the roller 52 are fixed, and either one or both of the rollers 53 and 54 have a role of a tension roller for tensioning the belt 55. When the contact angle θ is made as large as possible, the frictional force is increased, so that a large feeding force and winding force of the flexible rod 11 can be obtained.

It should be noted that in FIG. 3 showing the device of the structure which is the basis of the present invention, instead of the device including the pinch rollers 24, 25 and the holder 27, the rollers 52, 53, 54 and the belt 55 shown in FIG. 6 are included. With the device 50 in place, the structure is essentially the same as the embodiment of FIG.

[Effect of device]

In the device of the present invention, a belt stretched around a roller is used instead of the pinch roller, and a flexible rod is pressed and sandwiched between the belt and the main roller to be pushed into the cylindrical container. Therefore, the contact angle between the belt and the main roller can be made large, so that the frictional force becomes large, and the large unwinding force and winding force which cannot be obtained by the pinch roller can be obtained. In particular, when pushing out the components in the container, more reliable pushing-out of the components can be achieved as compared with the conventional device using the pinch roller.
