Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of attracting and transporting an object by magnetic force, and more particularly, to a method of transferring an object from a first transport path to a second transport path. The present invention relates to a transfer mechanism for converting a transfer state of an object from a transfer state of a first transfer path to a transfer state of a second transfer path.

[0002]

2. Description of the Related Art For example, when a conveyed object such as a magnetic lead frame or a hoop terminal is conveyed, for example, the conveying speed is increased from one conveying path (first conveying path). There is a case where it is necessary to transfer (transfer) the transported object to another different transport path (second transport path).

In such a case, conventionally, in order to change the transfer conditions (such as the transfer speed in the case of continuous feed and the transfer distance in the case of intermittent feed), a pusher or feed claw is provided separately from the original transfer mechanism. A transfer mechanism such as an extrusion method or pick and place method by
A method of transferring from one transfer path to the other transfer path, or synchronizing the transfer operation of one transfer path and the transfer operation of the other transfer path to ensure that the transferred object is transferred to the other transfer path A method of performing a predetermined transport operation after the transfer is used.

However, when the transfer device is provided with a transfer mechanism different from the original transfer mechanism as described above, (a) the configuration becomes complicated, the equipment becomes large, and the cost is reduced. (B) Since the operation of the transfer mechanism by the pusher or the feed claw is usually a reciprocating operation, the return operation time affects the tact time, which hinders an increase in speed.
(c) In addition, when the speed is forcibly increased, there is a problem that vibration and noise are caused. In addition, as described above, if the transfer operation of one transfer path and the transfer operation of the other transfer path are synchronized at the time of transfer, processing during each transfer path cannot be performed during transfer. However, there is a problem that the working time must be shortened.

The present invention solves the above-mentioned problems, and does not increase the size of the equipment. When the object is transferred from the first transfer path to the second transfer path, the transfer of the object is performed. It is an object of the present invention to provide a transport conversion mechanism that can quickly convert the transport conditions (for example, the transport speed in the case of continuous feeding and the transport distance in the case of intermittent feeding).

[0006]

To achieve the above object, a transport conversion mechanism according to the present invention (claim 1) is configured to attract and transport an object to be transported onto a transport medium by magnetic force. When transferring the transported object from the first transport path to the second transport path, which is also configured to attract and transport the transported object onto the transport medium by magnetic force, the transport state of the transported object is changed to the second transport path. 1
In a transfer conversion mechanism for converting a transfer state of a transfer path from a transfer state of a transfer path to a transfer state of a second transfer path, a magnet is disposed at a boundary between the first transfer path and the second transfer path, and a magnet is applied to the boundary from the magnet. By controlling the magnetic force, the transfer state of the transferred object is changed from the transfer state of the first transfer path to the transfer state of the second transfer path.

[0007] A magnet is provided at the boundary between the first and second transport paths and the magnetic force applied to the boundary from the magnet is controlled to transfer the object from the first transport path to the second transport path. The transfer state of the transferred object during transfer (such as the transfer speed for continuous feed and the transfer distance for intermittent feed) is quickly converted from the transfer state of the first transfer path to the transfer state of the second transfer path. It becomes possible to do. Also, since the conventional pusher or feed claw push method or pick and place method is not used, the return operation time of the pusher or feed claw does not affect the tact time, so during transfer, It is possible to ensure that a sufficient work time can be secured by avoiding that processing work or the like on each transport path cannot be performed, and in that respect, it is also possible to increase the speed of transport.

Further, in the transport conversion mechanism according to the present invention (claim 2), the transport medium may be a belt made of a non-magnetic material movably disposed on a fixed magnet, or may be covered on the outer peripheral surface by a magnetic force. It is characterized in that it is a roller that rotates while adsorbing a conveyed object.

A transport medium forming the first transport path and the second transport path is a belt made of a non-magnetic material movably disposed on a fixed magnet, or is rotated by attracting an object to be transported by magnetic force. By applying the present invention to a roller configured to be able to perform the transfer, it is possible to efficiently convert the transfer state from the transfer state of the first transfer path to the transfer state of the second transfer path. become.

Further, according to a third aspect of the present invention, there is provided a transport conversion mechanism for controlling a magnetic force applied to the boundary from a magnet disposed at a boundary between the first transport path and the second transport path. One of a method of disposing a magnet at the boundary portion so as to be displaceable and changing the position of the magnet, and a method of arranging an electromagnet at the boundary portion and turning on and off power supply to the electromagnet are used. It is characterized by:

Either a method of disposing a magnet at the boundary and displacing the magnet, or a method of disposing an electromagnet at the boundary and turning ON / OFF the power supply to the electromagnet is used. This makes it possible to easily control the magnetic force at the boundary between the first transport path and the second transport path, and to transfer the transported object from the first transport path to the second transport path. It is possible to efficiently and quickly convert the transport state of the object (the transport speed in the case of continuous feed, the transport distance in the case of intermittent feed, etc.). As a driving means for moving the magnet, an air cylinder, an electromagnetic solenoid, or the like can be used. In this case, the operation amount is smaller than that of a conventional pusher or feed claw pushing method or a pick-and-place method. , It is easy to increase the speed, and there is little problem in terms of vibration and noise.

Further, the transport conversion mechanism of the present invention (claim 4) is a method for controlling a magnetic force applied to the boundary from a magnet disposed at a boundary between the first transport path and the second transport path. A first conveying path-side magnet is disposed at a position near the first conveying path at the boundary, and a second conveying path-side magnet is disposed at a position near the second conveying path; A method of changing the position of the magnet, and using an electromagnet as the first and second conveyance path side magnets, and turning on the power supply to the electromagnet.
It is characterized in that one of the methods for turning off is used.

A method in which a first conveying path side magnet and a second conveying path side magnet are arranged at the boundary and the positions of the first and second conveying path side magnets are changed, or an electromagnet is used as the first and second conveying path side magnets. To turn on / off the power supply to the electromagnet
By using the method described above, it is possible to efficiently control the magnetic force applied to the boundary from the magnet disposed at the boundary between the first transport path and the second transport path.

Further, the transport conversion mechanism of the present invention (claim 5) controls the magnetic force applied to the boundary from the magnet disposed at the boundary between the first transport path and the second transport path. The transfer is performed when the transferred object reaches the boundary between the first transfer path and the second transfer path.

When the article to be transported reaches the boundary between the first transport path and the second transport path, the magnetic force near the boundary between the first transport path and the second transport path is controlled so that the first transport path is controlled. It is possible to efficiently convert the transport state from the transport state of the road to the transport state of the second transport path.

Further, in the transport conversion mechanism of the present invention (claim 6), the transport mode of the first transport path and the second transport path is as follows: (a) a combination of continuous feeds for continuously transporting an object to be transported; In the case where the transport speed of one of the first transport path and the second transport path is higher than the other transport speed, (b) a combination of intermittent transport for intermittently transporting the article to be transported, When the transport distance in one of the transport steps of the first transport path and the second transport path is larger than the other transport distance,
(c) It is characterized in that it is one of the combinations of continuous feed and intermittent feed.

By controlling the magnetic force applied to the boundary portion, the transport mode of the first transport path and the second transport path can be controlled by a combination of continuous feeds, a combination of intermittent feeds, or a combination of continuous feeds and intermittent feeds. In any of the combinations of feeding, as described below, the transport state of the transported object can be efficiently converted from the transport state of the first transport path to the transport state of the second transport path.

[Case of Combination of Continuous Feeding] In this case, as shown in FIG. 1, a first transport 12 in which a first belt 12 made of a non-magnetic material is movably disposed on a first magnet 11 An example will be described in which the object 1 is transferred from the path 12a to a second conveyance path 22a in which a second belt 22 made of a non-magnetic material is movably disposed on a second magnet 21. The first transport path 12a and the second transport path 22a are both continuous feeds, and the transport speed of the second transport path 22a is の of the transport speed of the first transport path 12a.

First, as shown in FIG. 1 (a), the first transferred object 1 (1a) is moved to the second conveying path side magnet 23 of the boundary portion A.
(At the lower position) and at a position straddling the second conveyance path 22a, and in a state where the tip end of the second transferred object 1 (1b) reaches the end of the first magnet 11, The transported object 1 (1a) is constrained by the transport state of the second transport path 22a, and is continuously transported on the second transport path 22a at a transport speed of １ ／ of the transport speed of the first transport path 12a. In the transferred object 1 (1b), the first conveyance path magnet 13 is in the upper position (that is, the first conveyance path magnet 13 is in the ON state), and the second conveyance path magnet 23 is in the lower position. (Ie, there is a state corresponding to the OFF state of the second conveying path side magnet 23), the transferred object 1 (1b) is
2A, the sheet is conveyed by the first belt 22, and reaches the boundary A between the first conveyance path 12a and the second conveyance path 22a as shown in FIG. 1B.

In this state, as shown in FIG.
When the conveyance path magnet 13 moves to the lower position and the second conveyance path magnet 23 moves to the upper position, the transferred object 1 (1b) releases the restriction of the first conveyance path magnet 13 and releases the restriction of the second conveyance path magnet 23. Therefore, the conveyance state is restricted by the conveyance state of the second conveyance path 22a. That is, as shown in FIG. 1D, the transported object 1 (1b) is attracted by the second transport path side magnet 23 and the second magnet 21, and the second transport path 22
In the transporting state of a, the sheet is transported on the second transporting path 22a at a transporting speed of 被 of the transporting speed of the first transporting path 12a so as to be continuous with the transported object 1 (1a).

Here, the case where the transport speed of the second transport path 22a is smaller than the transport speed of the first transport path 12a (1/2 of the transport speed of the first transport path 12a) has been described. As described above, the conversion is performed in the same manner when the transport speed of the second transport path 22a is higher than the transport speed of the first transport path 12a. For example, in the state shown in FIG. 2A, the transported object 1 (1a) is on the second transport path 22a, and is constrained by the transport state of the second transport path 22a, so that the first transport The transported object 1 (1b) is continuously transported on the second transport path 22a at a transport speed higher than the transport speed of the path 12a, but the tip end of the transported object 1 (1b) reaches above the terminal end of the first transport path side magnet 13. However, since the first conveyance path side magnet 13 is at the upper position and the second conveyance path side magnet 23 is at the lower position, the first conveyance path side magnet 23 is restrained by the conveyance state of the first conveyance path 12a,
By the belt 12 forming the transport path 12a, the belt is transported at a transport speed lower than the transport speed of the second transport path 22a.
As shown in (b), the first transport path 12a and the second transport path 22
A reaches the boundary A of FIG.

In this state, as shown in FIG.
When the conveyance path magnet 13 moves to the lower position and the second conveyance path magnet 23 moves to the upper position, the transferred object 1 (1b) releases the restriction of the first conveyance path magnet 13 and releases the restriction of the second conveyance path magnet 23. As a result, it is constrained by the transport state of the second transport path 22a. As a result, as shown in FIG. 2D, the sheet is conveyed on the second conveyance path 22a at a conveyance speed higher than the conveyance speed of the first conveyance path 12a.

[Combination of Intermittent Feeding] First, the first transport path and the second transport path are both intermittent transports.
When the transport distance at the time of each intermittent feeding in the first transport path is longer than the transport distance of the second transport path, for example, as shown in FIG. When the object 1 (1a) is located at a position straddling the second conveying path side magnet 23 (located at the lower position) and the second conveying path 22a,
Due to the restraint of the transport state of the second transport path 22a, the second transport path 2 has a transport distance smaller than the transport distance of the first transport path 12a.
It will be conveyed intermittently on 2a. On the other hand, the transported object 1 whose leading end is on the end of the first transport path side magnet 13
(1b) is constrained by the first transport path 12a and is intermittently transported at a transport distance longer than the transport distance of the second transport path 22a.

Then, as shown in FIG. 3B, when the article 1 (1b) is conveyed and reaches the boundary A between the first conveying path 12a and the second conveying path 22a, the first The conveyance path side magnet 13 and the second conveyance path side magnet 23 move, and FIG.
As shown in (1), when the first transport path side magnet 13 is at the lower position and the second transport path side magnet 23 is at the upper position, the transferred object 1 (1b)
Is released from the constraint of the first transport path 12a and is restrained by the second transport path side magnet 23, and the transport state is restricted by the transport state of the second transport path 22a. as a result,
The transported object 1 (1b) is intermittently transported on the second transport path 22a by a transport distance shorter than the transport distance of the first transport path 12a (FIG. 3D).

Here, the case where the transport distance of the second transport path 22a at the time of each intermittent feed is smaller than the transport distance of the first transport path 12a has been described, but the transport distance of the second transport path 22a is the first transport distance. Even when the transfer distance is longer than the transfer distance of the transfer path 12a, the transfer of the transfer state is performed by the operation according to the above example. That is, as shown in FIG.
The transported object 1 (1a) on the second transport path 22a
Is transported intermittently on the second transport path 22a at a transport distance longer than the first transport path 12a.
In addition, the transported object 1 (1b) has a leading end portion above the terminal end of the first transport path side magnet 13, but the first transport path side magnet 13 is at the upper position, and the second transport path side magnet 23 is Since it is at the lower position, it is constrained by the transport state of the first transport path 12a and is transported intermittently at a transport distance smaller than the transport distance of the second transport path 22a.
A reaches the boundary A of FIG.

In this state, as shown in FIG.
When the conveyance path magnet 13 moves to the lower position and the second conveyance path magnet 23 moves to the upper position, the transferred object 1 (1b) releases the restriction of the first conveyance path magnet 13 and releases the restriction of the second conveyance path magnet 23. Receiving state, the transport state is changed to the second transport path 22a.
Is constrained. As a result, as shown in FIG. 4D, the transported object 1 (1b) has a transport distance longer than the transport distance of the first transport path 12a.
a is intermittently conveyed.

[Combination of Continuous Feeding and Intermittent Feeding] First, a case where the first transport path is continuous feeding and the second transport path is intermittent feeding will be described. As shown in FIG. 5 (a), when the article 1 (1a) reaches the boundary A between the first transport path 12a for continuous feed and the second transport path 22a for intermittent feed, the first transport path side Since the magnet 13 is located at the lower position and the second transport path side magnet 23 is located at the upper position, the transported object 1 (1a) is restrained by the transport state of the second transport path 22a. That is, the transferred object 1 (1a) is
It is intermittently transported under the transport conditions of the transport path 22a, and FIG.
As shown in (2), it is transported to above the second magnet 21 forming the second transport path 22a, and stops at that position. Note that the transferred object 1 (1a) is already in the first transfer path 12
Since the restriction of a is completely removed, the sheet is intermittently conveyed thereafter according to the conveyance conditions of the second conveyance path.

On the other hand, the transported object 1 (1b) restricted by the transport conditions of the first transport path 12a is continuously transported, and the leading end reaches the end of the first transport path side magnet 13. At this point, as shown in FIG.
3 moves to the upper position, and the second conveying path side magnet 23 moves to the lower position, the transferred object 1 (1b) is continuously restrained by the first conveying path side magnet 13, and its leading end follows the conveying conditions of the first conveying path 12a. The portion is continuously conveyed to a position reaching above the second conveying path side magnet 23 as shown in FIG.

Although not particularly shown, the transported object 1
(1b) is further conveyed and reaches a position above the first conveying path side magnet 13 and the second conveying path side magnet 23 (that is, a position corresponding to the position of the transferred object 1 (1a) in FIG. 5A). When the first transport path magnet 13 moves to the lower position and the second transport path magnet 23 moves to the upper position, the transferred object 1 (1b)
Under the constraint of the second transport path 22a, the paper is intermittently transported on the second transport path 22a.

Next, the first transport path 12a is intermittently fed,
An operation in the case where the transport path 22a is a continuous feed will be described. As shown in FIG. 6A, the transferred object 1 (1a) is
Since the object 1 (1a) is released from the restraint of the first transport path 12a because it is located at a position straddling the second transport path side magnet 23 (located at the lower position) and the second transport path 22a at the boundary portion A, the first transport path 12a is released. Under the constraint of the two transport paths 22a, the paper is continuously transported on the second transport path 22a.

On the other hand, the article 1 (1b) to be transported has its leading end reaching above the end of the first transport path side magnet 13 (at the upper position) of the boundary A, and the first transport path magnet 1
3 is in the upper position, and the second conveying path side magnet 23 is in the lower position.
While the object 1 (1a) is intermittently conveyed according to the conveyance condition a and is continuously conveyed through the second conveyance path 22a, only a predetermined time (a stop time in the intermittent feeding cycle) is maintained. It is stopped at that position. Thereafter, when a predetermined time elapses, the transported object 1 (1b) is intermittently transported and moves by a predetermined distance, and is located above the first transport path side magnet 13 and the second transport path side magnet 23 (that is, at the boundary portion). A) is reached. Then, at this point, as shown in FIG.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be shown and features thereof will be described in more detail. FIG. 7 is a perspective view showing the configuration of the transport conversion mechanism according to one embodiment of the present invention.

The transport conversion mechanism of this embodiment comprises a fixed magnet 11, a non-magnetic belt (transport medium) 12 movably disposed on the fixed magnet 11, and rollers 15a for transporting the belt 12. Similarly, a fixed magnet 21, a belt (conveying medium) 22 made of a nonmagnetic material movably disposed on the fixed magnet 21, and the belt 22 are conveyed from the first conveying path 12 a including the fixed magnet 15. Rollers 25a, 2
5b, a transfer conversion mechanism for converting a transfer state when transferring a transferred object (a magnetic work such as a lead frame or a hoop terminal) 1 to a second transfer path 22a including
Drive for moving up and down the first conveying path side magnet 13 and the first conveying path side magnet 13 disposed at a boundary A between the first conveying path 12a and the second conveying path 22a near the first conveying path 12a. The apparatus 14 includes a second conveying path side magnet 23 disposed at a position close to the second conveying path 22a, and a driving means 24 for vertically moving the second conveying path side magnet 23. In this embodiment, the first transport path side magnet 13 and the second
A permanent magnet is used as the conveyance path side magnet 23, and an air cylinder is used as the driving means 14, 24 for vertically moving the first conveyance path side magnet 13 and the second conveyance path side magnet 23.

Next, the operation of the transport conversion mechanism configured as described above will be described with reference to FIGS. For example, when the first transport path 12a is intermittent feed and the second transport path 22a is continuous feed, as shown in FIG. 6A, the first transported object 1 (1a) is Transfer path side magnet 23
(Located at the lower position) and reaches a position straddling the second conveyance path 22a, and is intermittently fed on the first conveyance path 12a.
At the time when the leading end portion of the first transported object 1 (1b) reaches above the first transport path side magnet 13 (at the upper position) of the boundary portion A, the first transport path side magnet 13 is in the upper position, 2 Since the conveyance path side magnet 23 is at the lower position,
In (1a), the first transport path 12a is released from the restraint and the second transport path 22a is restrained, and the paper is continuously transported on the second transport path 22a.

On the other hand, the transferred object 1 (1b) is moved to the first conveying path 12a because the first conveying path side magnet 13 is at the upper position.
Is constrained, and is conveyed intermittently in accordance with the conveyance conditions of the first conveyance path 12a, and the object 1 (1a) is continuously conveyed along the second conveyance path 22a for a predetermined time ( It stops at that position only during the intermittent feed cycle (stop time).

Thereafter, when a predetermined time elapses, the transferred object 1 (1b) is intermittently conveyed and moves by a predetermined distance, and moves above the first conveying path side magnet 13 and the second conveying path side magnet 23 (ie, To the boundary A). At this point, as shown in FIG. 6C, the first transport path magnet 13 is moved to the lower position, and the second transport path magnet 23 is moved to the upper position, so that the transported object 1 (1b) is moved to the second position. The first transport path 12a is released from the restraint, and is constrained to the transport state of the second transport path 22a, and is continuously transported on the second transport path 22a. In this way, the conversion from the intermittent feed to the continuous feed is performed smoothly, so that the transfer from the first transport path to the second transport path can be reliably performed.

It should be noted that, even when the transport mode of the first transport path and the second transport path is a combination of continuous feeds or a combination of intermittent feeds, a procedure similar to that of the above embodiment is used. In addition, the transport state of the transported object can be reliably converted from the transport state of the first transport path to the transport state of the second transport path.

In the above-described embodiment, a case has been described in which permanent magnets are used as the first transport path magnet 13 and the second transport path magnet 23, but electromagnets can be used instead of permanent magnets. In this case, by turning on and off the power supply to the electromagnet, the magnetic force at the boundary can be controlled, so that it is not necessary to provide a driving unit for vertically moving the magnet.

Further, in the above-described embodiment, the case where the air cylinder is used as the driving means for moving the magnet up and down has been described. However, other driving means such as an electromagnetic solenoid can be used.

Further, in the above-described embodiment, the case has been described in which the transport medium constituting the transport path is a belt. However, the transport medium is attracted by magnetic force to rotate the transport medium. The present invention can be applied to the conversion of the transport state between the transport paths as described above. Further, the present invention can be applied to conversion of a conveyance state in a case where one conveyance path uses a roller and the other uses a belt.

In addition, the present invention is not limited to the above-described embodiment in other respects. The type and specific shape of the object to be transported, and the specific shapes of the first and second transport paths are not limited. With respect to the configuration, the moving direction of the magnet when controlling the magnetic force at the boundary by changing the position of the magnet disposed at the boundary between the first transport path and the second transport path, and the like, there are various types within the scope of the invention. Applications and modifications are possible.

As described above, in the transfer conversion mechanism of the present invention (claim 1), a magnet is disposed at the boundary between the first transfer path and the second transfer path, and the magnetic force applied to the boundary from the magnet. Is controlled, large-scale equipment is not required, and the transfer state of the transferred object when transferring the transferred object from the first transfer path to the second transfer path (the transfer speed in the case of continuous feeding). And the transport distance during intermittent feeding) can be quickly converted from the transport state of the first transport path to the transport state of the second transport path.
Also, since the conventional pusher or feed claw push method or pick and place method is not used, the return operation time of the pusher or feed claw does not affect the tact time, so during transfer, It is possible to ensure that a sufficient work time can be secured by avoiding that processing work or the like on each transport path cannot be performed, and in that respect, it is also possible to increase the speed of transport.

The transport medium forming the first transport path and the second transport path is a belt made of a non-magnetic material movably disposed on a fixed magnet, or adsorbs an object to be transported by magnetic force. By applying the present invention to a roller configured to be rotatable, it is possible to efficiently convert the transport state from the transport state of the first transport path to the transport state of the second transport path. Can be.

Further, in the transport conversion mechanism of the present invention,
Either a method of disposing a magnet at the boundary and displacing the magnet and changing the position of the magnet, or a method of disposing an electromagnet at the boundary and turning ON / OFF the power supply to the electromagnet can be used. This makes it possible to easily control the magnetic force at the boundary between the first transport path and the second transport path, and to transfer an object to be transported from the first transport path to the second transport path. It is possible to efficiently and quickly convert the transport state of the transported object (the transport speed in the case of continuous feed, the transport distance in the case of intermittent feed, etc.). Air cylinders, electromagnetic solenoids, etc., which are usually used as driving means for moving magnets, have a smaller amount of operation than conventional pusher or feed claw push-out or pick-and-place methods, so higher speeds have been achieved. It is easy to operate, and it is unlikely to cause problems in terms of vibration and noise.

Further, in the transport conversion mechanism of the present invention,

In the transport conversion mechanism of the present invention,
When the transported object reaches the boundary between the first transport path and the second transport path, the magnetic force near the boundary between the first transport path and the second transport path is controlled. The conversion of the transfer state from the state to the transfer state of the second transfer path can be performed efficiently.

Further, in the transport conversion mechanism of the present invention, the transport mode of the first transport path and the second transport path may be any of a combination of continuous feeds, a combination of intermittent feeds, and a combination of continuous feed and intermittent feeds. It is also possible to apply to cases.
