DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tray supply / storage device, for example, for handling a tray in which various components such as electronic components are stored in an aligned state, and for manufacturing the stored components in an electronic circuit board or the like. Used to provide for use.

[0002]

2. Description of the Related Art As shown in FIGS. 5 and 6 (a) to 6 (d), a conventional apparatus of this kind is moved up and down by a cylinder k under a tray storage position d and at a lower movement position. And a tray transfer body g for transferring the tray e between a tray storage position d and a position (not shown) for receiving the supply of the tray e, or a position (not shown) for using the components stored in the tray e for use. . At the tray storage position d, a pair of gripping members c that are opened and closed via a toggle b by a cylinder a shown in FIG. 5 are provided. The pair of tray gripping members c enter the gap j between the trays e stacked and stored at the tray storage position d on the opposing surfaces as shown in FIG. 6 (a), 6 (c) and 6 (d) from the side, and has a projection h to be engaged, and this engagement is performed in the order of FIGS. 6 (b) and 6 (c). Accordingly, the tray e with which the projection h is engaged is supported together with the tray e above, and is supported in the storage state at the tray storage position d, and the tray e below it is supported in the storage state. As shown in FIG. 6D, the sheet is received by the tray transfer body g and moved down to separate it, and in this state, the parts can be moved to a position where they can be used. (D) → (c) → (b) →
After the tray e stored in the tray storage position d is received by the tray transfer body g moving upward in the order of (a), the tray h is supported and stored by engaging the projection h under the lowermost tray e. It can be so.

Thus, the trays e can be stacked one by one at the tray storage position d and stored one by one or separated from the stacked storage state at the tray storage position d and supplied to a predetermined position. In addition, it is possible to automatically achieve the use of the contained components.

[0004]

However, in the commercially available trays e, the size of the gap j formed between the trays when they are stacked is not constant. There is a case where the trays e cannot be separated, and the trays e stored in the stacked state cannot be surely separated one by one. In the case of a small tray e, the gap j may be small or not. In this case, the separation of the tray e becomes impossible.

Therefore, it is conceivable that the tray e is gripped only by the frictional force from the side without the protrusion h. However, in this case, the gripping force of the tray gripping member c cannot withstand the weight of the tray e, and there is a fear that the tray e falls, which is a practical problem.

SUMMARY OF THE INVENTION It is an object of the present invention to securely supply and separate trays irrespective of the state of a gap between them, and furthermore, to securely store and supply trays without fear of falling of stacked and stored trays. It is to provide a device. It is another object of the present invention to provide an electronic component working machine such as a bump bonder device and an electronic component mounting machine provided with such a tray storage / supply device.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a method of storing trays one by one in a tray storage position, or in a stacked storage state in a tray storage position.

Alternatively, the apparatus has a tray transfer body for transferring the tray between a position where the tray is to be used and a tray transfer position. The tray is supported at the tray storage position, and the support is released by retreating from the engagement position, or the tray is opened and closed to receive the tray stored by the upward movement of the tray transfer body at the tray storage position. A stopper member, a tray gripping member that grips the tray received by the receiving member from the side and opens and closes to release the gripping, and an opening and closing mechanism that opens and closes the tray receiving member and the tray gripping member in a timely manner It is characterized by having.

In such a configuration, the tray receiving member and the tray gripping member can be opened and closed in a timely manner by the opening / closing mechanism, and when one tray is lifted to the tray storage position by the tray transfer member, the tray receiving member can be opened and closed. When the tray is opened prior to the tray gripping member, even if there is little or no gap between the trays, the lifting tray can receive the tray until the tray gripped by the tray gripping member in the tray storage position. It is possible to arrive without interfering with the members, and after the arrival, the tray holding member is opened, so that the lifted tray is received in the tray storage position, and when there is no stored tray, it is stored alone, If there is an existing storage tray, store it in a stack while lifting it at the same time. Each time the tray receiving member and the tray gripping member are closed, the receiving member is engaged with the lower side of the stored tray from the side to receive and support it, and the tray gripping member is stored. The trays held from the side can be reliably supported by the cooperation of the tray receiving member and the tray gripping member, and the trays that are stored in a stacked state can be securely held without fear of the tray falling off due to its own weight. The only thing that needs to be supported by the tray gripping member while tray support is required is that the tray transfer unit moves down slightly after the trays are lifted one by one to the tray storage position. This does not result in the tray dropping and the safety is not compromised.

Further, when the trays stored in the stacked state are separated one by one and supplied to a predetermined position where parts are used, the tray receiving member and the tray gripping member are opened and moved upward. After placing the trays stored in the tray transfer body, when the tray transfer body moves down by the amount of one tray stacked, the tray gripping member is closed prior to the tray receiving member. One lowermost tray can be separated from the stored tray by the subsequent lowering of the tray transfer body, and when the separated lowermost tray is moved down to a certain position, the tray receiving member is moved. By closing the tray, the tray receiving member is engaged from the side with the lower portion of the tray gripped at the storage position without interfering with the separated lowermost tray and returns to the state of receiving and supporting it. Even if the gap between the trays is small or not, it is possible to reliably separate the stacked and stored trays one by one, and to hold the tray by the tray holding member while the tray needs to be supported. Only when the trays are separated one by one when the tray moved out of the storage position is moved down to a position where it does not interfere with the closing operation of the tray receiving member, only for a moment. This does not cause the tray to fall,
The security is not compromised.

In the present invention, the tray receiving member is further urged so as to maintain the engagement position with the tray, and the opening / closing mechanism of the tray receiving member includes a cam provided on the tray transfer body and a tray receiving member. A cam follower provided on the member, and in conjunction with the tray transfer body lifting the tray to the tray storage position, the cam retreats the tray receiving member from the engagement position to the side via the cam follower, thereby forming the tray transfer body. It is preferable that the cam return the tray receiving member to the engaging position via the cam follower in conjunction with the lowering of the tray from the lifting position of the tray storage position.

In such a configuration, in addition to the above-described operation of the present invention, the tray receiving member is always in the engagement position with the lower portion of the tray by urging, and the cam receiving member is connected to the cam which is interlocked with the vertical movement of the tray transfer body. By the operation with the cam follower, the opening and closing of the tray transfer body is repeatedly and accurately achieved at a preset mechanical timing, so that the opening / closing timing of the tray receiving member does not go wrong or the opening / closing timing is not mistaken, An inexpensive device with a simple structure and control.

[0012]

Alternatively, a tray receiving member 4 that opens and closes to receive the tray stored in the tray storage position 2 by the upward movement of the tray transfer body 3 in the order shown in (d) → (c) → (b) of FIG.
And the tray 1 received by the tray receiving member 4
Gripping from the side by frictional force, and a tray gripping member 5 that opens and closes to release the gripping, and a tray receiving member 4 and a tray gripping member 5 in order to open and close in a timely manner.
For example, individual opening / closing mechanisms 6 and 7 are provided. However, in some cases, a single opening and closing mechanism may be used.

As shown in FIGS. 1 and 2, the tray receiving member 4 is an L-shaped lever member pivotally supported by a shaft 11 on a fixed frame 12 mounted on the left and right outer surfaces of the tray housing cover 16. 2A, which is provided on the left and right sides of the tray storage position 2 and is engaged with the lower side of the tray 1 from both sides by a spring 13 which is operated between the tray 1 and the fixed frame 12.
It is urged to maintain the engagement position shown in (d). As shown in FIGS. 1 and 2, the opening / closing mechanism 6 of the tray receiving member 4 includes a cam 14 provided on the tray transfer body 3 and a cam follower 15 provided on the tray receiving member 4. The transfer body 3 moves the tray 1 from FIG. 2 (d) to (c).
The cam 14 interlocks with the tray receiving member 4 via the cam follower 15 in conjunction with lifting to the tray storage position 2 in the order shown in FIG.

The tray gripping member 5 is supported so as to be able to open and close left and right under the guidance of a rectilinear guide 19 provided on the back of the tray storage unit cover 16. Hydraulic cylinder 17
Is opened and closed via the toggle 18.

FIG. 2A shows a state in which the trays 1 shown in FIG. 2A are stacked and stored, and the stored trays 1 are separated one by one as shown in FIG. The operation states for sequentially supplying to a predetermined position are shown in order.

The operation of FIG. 2 will be described in accordance with the specific operation sequence of FIG. 3. When it is said that the components have been used by using the tray 1, the tray supply signal enters a control system (not shown). Then, the sequence of FIG. 3 is executed.

First, when the tray transfer body 3 is located below the tray storage position 2 as shown in FIGS. 1 and 2A, it is moved upward as shown in FIG. 2B. If there is no tray transfer body 3 in the tray storage position 2, the tray is moved to the tray storage position 2 and then moved up.

Tray 1 in which tray transfer body 3 is stored
Height, for example, in the present embodiment, the tray 1 in which the tray receiving member 4 is stored through the cam 14 and the cam follower 15 by the upward movement of the tray transfer body 3 in the present embodiment. The tray receiving table 3a for receiving the tray 1 provided on the tray transfer body 3 comes into contact with the lower surface of the lowermost stacked tray 1 by disengaging the lower tray 1 from the lower tray. In the state shown in FIG. 2B at the height, the upward movement of the tray transfer body 3 is stopped. This upward movement position can be determined by setting the maximum extension stroke of the cylinder 9. However, depending on the type of the vertical movement actuator, the fact that the tray transfer body 3 has reached the predetermined receiving height is determined by the movement of the tray transfer body 3 or a member linked thereto by a limit switch, a photo sensor, a reed switch, or the like. It is also possible to detect from the position, or from the count of the lapse of time from the first time the tray transfer body 3 has moved upward, and stop the upward movement of the tray transfer body 3 based on the detection results.

After the upward movement of the tray transfer body 3 is stopped, the tray gripping member 5 is opened as shown by an arrow in FIG. As a result, the tray 1 supported at the tray storage position 2 becomes free and is placed on the tray receiving table 3a of the tray transfer body 3 by its own weight. Next, the tray transfer body 3 is moved down by one stack bulk H of the tray 1 as shown in FIG. 2C, and the lowermost tray 1 is located outside the tray storage position 2 and is at the tray storage position 2. The tray holding member 5 is closed as shown by an arrow in FIG. The state of the separation height can be determined by setting the stroke of the cylinder 9 in the middle. However, also in this case, the closing timing of the tray gripping member 5 can be determined by the limit switch, the photo sensor, the reed switch, the count of the elapsed time from the first movement of the tray transfer body 3 and the like.

The lowermost tray 1 can be separated from the stored tray 1 by the subsequent lowering of the tray transfer body 3, and when the separated lowermost tray 1 is lowered to a certain position. That is, by closing the tray receiving member 4 when a space where the tip of the tray receiving member 4 can be inserted is formed between the lowermost tray 1 and the tray 1 thereon, the separated lowermost The tray receiving member 4 is engaged with the lower part of the tray 1 gripped at the storage position from the side without interfering with the tray 1 and receives and supports it.

After the tray transfer body 3 is further lowered and the lowering of the tray transfer body 3 is stopped in a state where the separated tray 1 has reached the transfer height to a predetermined position, the tray transfer body 3 is removed. The tray 1 is moved to a predetermined position to be used and stopped, and the tray 1 is transferred by a transfer mechanism (not shown) to a component supply unit of a circuit board manufacturing machine or the like so that the components contained therein are used. When the transfer of the tray 1 is completed, the tray transfer body 3 is returned to a position below the tray storage position 2 and stopped, so as to wait for the next tray supply.

However, the accommodated components can be used without transferring the tray. In this case, the tray transfer body 3
Although there is a disadvantage that the component cannot be recovered until the components have been used, the tray transfer mechanism can be omitted.

As described above, in the present embodiment, the tray holding member 5 is housed in addition to the lateral engagement with the lower surface of the tray 1 in which the tray receiving member 4 is housed to receive and support it. Since the tray 1 is gripped from the side by a frictional force, the trays 1 stored in a stacked state can be reliably supported by the cooperation of the tray receiving member 4 and the tray gripping member 5, and the tray 1 has its own weight. It is safe without fear of falling off.

When the trays 1 stored in the stacked state are separated one by one and supplied to a predetermined position where components are used, the following operation is performed. First, after the tray receiving member 4 and the tray gripping member 5 are opened and the tray 1 stored in the tray transfer body 3 moved upward is placed, the tray transfer body 3 is lowered by the stack height of one tray 1 by H. When moved, the tray gripping member 5 is closed prior to the tray receiving member 4, and supports the tray 1 except for the lowermost tray 1 by frictional force.

The lowermost tray 1 can be separated from the stored tray 1 by the subsequent lowering of the tray transfer body 3, and when the separated lowermost tray 1 is lowered to a certain position. That is, by closing the tray receiving member 4 when a space where the tip of the tray receiving member 4 can be inserted is formed between the lowermost tray 1 and the tray 1 thereon, the separated lowermost The tray receiving member 4 is engaged from the side with the lower portion of the tray 1 held at the storage position without interfering with the tray 1 of the other, and returns to a state of receiving and supporting it. Therefore, the gap 21 formed between the trays 1
Even if the trays are small or not, the trays 1 in the stacked storage state can be reliably separated one by one,
While the tray 1 needs to be supported, only the gripping by the frictional force by the tray gripping member 5 is performed when the tray 1 is moved down to the outside of the tray storage position 2 when the trays 1 are separated one by one. Is moved down to a position where it does not interfere with the closing operation of the tray receiving member 4, and the upper tray 1 is gripped by the frictional force. Is small, so tray 1
This does not lead to a fall, and the safety is not impaired.

The tray transfer body 3 has a tray receiving table 3a for receiving the stored tray 1, and a large gap 21 is formed between the tray 1 and the tray 1.
Although there is no problem of interference with the tray receiving member 4 in the gap between the tray 1 and the tray transfer body 3,
Without providing such a tray receiving table 3a, the tray transfer member 3 can reach the position for receiving the lowest one of the stored trays 1 without interfering with the tray receiving member 4. The retreat timing of the stop member 4 may be advanced.

FIG. 4 shows an operation sequence when the trays 1 to be replenished at the predetermined positions are sequentially stored one by one in the tray storage positions 2, and the operation is completely opposite to the operation of supplying the trays 1. 2 (d) → (c) → (b) → (a), and the detailed description is omitted, but the tray receiving member 4 and the tray gripping member 5 are respectively opened and closed. When one of the trays 1 is opened and closed by the mechanism in a timely manner and is lifted by the tray transfer body 3 to the tray storage position 2 in the order shown in (d) → (c) → (b) of FIG. 4 is opened before the tray gripping member 5 as shown in the drawing, so that even if the gap 21 formed between the trays 1 is small or absent, the lifting tray 1 holds the tray gripping member 5 Hold at position 2 It can arrival as shown in (c) in FIG. 2 without interfering with the tray receiving member 4 until the tray 1 are, after arriving tray gripping member 5 in FIG. 2
(C), the tray 1 to be lifted is received in the tray storage position 2, and is stored alone when there is no stored tray 1, and when it is opened, As shown in FIGS. 2C and 2B, the tray receiving member 4 and the tray gripping member 5 are closed each time one tray 1 is stored while being simultaneously lifted and stored. As a result, the tray receiving member 4 is engaged with the lower part of the accommodated tray 1 from the side as shown in FIG. Holds the stored tray 1 from the side, and the tray 1 is safe without fear of falling off due to its own weight.

In the tray storing process, the tray holding members 5 only hold the trays 1 while the trays 1 need to be supported.
After being lifted, the tray transfer body 3 moves only slightly for a moment, so that this does not cause the tray 1 to fall and the safety is not impaired.

The opening and closing mechanism 6 of the tray receiving member 4
Is configured by the cam 14 and the cam follower 15 as described above, and the opening and closing of the tray receiving member 4 is set in advance by the function of the cam 14 and the cam follower 15 interlocked with the vertical movement of the tray transfer body 3. Since the opening / closing timing of the tray receiving member 4 is not disturbed or erroneously opened / closed, the apparatus is inexpensive with a simple structure and control.
