However, in this case, it is necessary to display on the display or the like that the feeder bank 11 has been properly mounted on the mounting section M1.

Further, the lifting mechanism may be replaced with a mechanism having the jack mechanism 15 as in the above embodiment, and may be configured as in a third embodiment shown in FIG. That is, the lifting mechanism L3 in the third embodiment includes an air cylinder 21 provided at the left end and a right end in the supply section M1 of the mounting apparatus M, and a pair of air cylinders provided at the cylinder rods of the air cylinders 21 and 21. Elevating plates 19 are provided. The feeder bank 11 supported by the carrier 10 is then moved to the cylinder rod 21 in the same manner as in the first embodiment.
By raising and lowering the elevating plates 19 and 19 together with a and 21a, the feeder bank 11 is raised and lowered and held at the component supply position.

The air cylinders 21 and 21 are
It is connected to a pneumatic circuit as shown in FIG. 4 so that air supply and cutoff are appropriately performed. That is, in FIG. 4, reference numeral 22 denotes a roller lever type mechanical valve attached to the locking plate 17 in place of the limit switch 18 in the first embodiment described above.

In the pneumatic circuit thus configured, when the feeder bank 11 is not mounted on the supply section M1 of the mounting apparatus M, that is, when the lever of the hand valve is
When it is on the FF side, each valve is in a connected state as shown in FIG. In this state, when the feeder bank 11 is mounted together with the carrier 10 on the supply section M1, the roller lever 22a of the mechanical valve 22 is pressed by the guide rod 10b protruding from the carrier 10, and the ON side block of the mechanical valve 22 (in the figure). , The block located on the upper side) is connected to the air source 20.

Here, the operator switches the operation lever 23a of the hand valve 23 to the ON side, and
When the N side block is connected to the ON side block of the mechanical valve 22 and the speed controllers 24 and 25,
The air supplied from the air source 20 is supplied to each valve 22,
23 and the speed controller 25 to the cylinder rod 21a.
Project upward. As a result, the lifting plate 19 pushes the feeder bank 11 upward, thereby engaging the engagement protrusion 11a with the engagement hole 17a to fix the position of the feeder bank 11. The air in the space on the immersion side of the air cylinder is discharged to the outside via the speed controller 24, the hand valve, and the silencer 26.

When removing the feeder bank 11, the operation lever of the hand valve 11 may be switched to the OFF side. That is, when the operation lever 11a is switched, the air supplied from the air source 20 is sent to the immersion side space via the mechanical valve 22, the hand valve 23, and the speed controller 24, so that the cylinder rod 21a is immersed. , The feeder bank 11 is lowered together with the elevating plate 19, and the engagement protrusion 11 a and the engagement hole 17
The engagement with a is released. The air supplied to the lower space of the air cylinder 21 is discharged to the outside via the speed controller 25, the hand valve 23, and the muffler 27. As a result, the feeder bank 11 can be taken out together with the carrier 10, and when the feeder bank 11 is taken out, the pressing on the roller lever 22a is released, the OFF-side block of the mechanical valve 22 is connected to the air source 20, and the circuit is in the initial state. Return to.

Next, a fourth embodiment of the present invention will be described.
In the fourth embodiment, a pilot check valve 28 is connected between one speed controller 25 and the hand valve 23 in the pneumatic circuit shown in the third embodiment, and a pilot signal of the pilot check valve 28 is transmitted. It is designed to be taken out from between the other speed controller 24 and the hand valve 23,
With such a circuit configuration, the air supply source 2
Even when air leaks or shuts off at 0, the cylinder rod 21a of the air cylinder 21 can be prevented from inadvertently lowering from the raised position.

That is, when the cylinder rod 21a projects, air is supplied to the projecting space of the air cylinder 21 via the valves 22, 23, the check valve 28, and the speed controller 25 as shown in FIG. Then, the air in the space on the immersion side of the air cylinder is discharged to the outside via the speed controller 24, the hand valve 23 and the muffler 26. At this time, the inside of the flow path from the speed controller 24 to the hand valve 23 is equal to the atmospheric pressure, and air serving as a pilot signal is not supplied to the check valve 28. Therefore, the check valve 28 is closed and the backflow of air is prevented. .

Therefore, when the cylinder rod is in the protruding state, even if air is shut off or leaks in the air supply source 20, the air pressure in the protruding space of the air cylinder is maintained by the backflow preventing action of the check valve 28, The projected state of the cylinder rod 21a is maintained. Therefore, the problem that the feeder bank 11 is inadvertently lowered and moved from the set position together with the carrier 10 does not occur. Further, when the feeder bank 11 is lowered due to the shutoff or leakage of the air supply source 20, when the air supply source 20 is restored, the feeder bank 11 suddenly rises, and an operator is scattered in this. May occur, but this fourth
In the embodiment, since the feeder bank 11 is kept at the raised position, such a danger is completely eliminated.

On the other hand, when the lever 23a of the hand valve 23 is switched to take out the feeder bank 11 from the mounting portion, the air from the air supply source 20 passes through the mechanical valve 22 and the OFF block of the hand valve 23, and then the speed controller The air is supplied to the immersion-side space of the air cylinder 21 through 24. At this time, a pressure higher than the atmospheric pressure is applied to the path from the hand valve 23 to the speed controller 24, and air as a pilot signal is supplied to the check valve 28, so that the check valve 28 is opened and the air cylinder 21 is opened. The air in the protruding space is sent out to the hand valve 23 via the speed controller 25 and the check valve 28, and is discharged therefrom via the silencer 27. That is, when taking out the feeder bank 11, the check valve 2
8, the lowering prevention state of the cylinder rod 21a is released, and the feeder bank 11 can be reliably lowered, and the engagement with the lifting plate 19 can be released.

Next, a fifth embodiment of the present invention will be described.
In the fifth embodiment, an air cylinder for raising and lowering the lift plate 19 is driven by a pneumatic circuit as shown in FIG. In FIG. 6, 30 is an electromagnetic valve connected to the air source 20, 31 and 32 are speed controllers connected between the electromagnetic valve 30 and the air cylinder 33, and 34 and 35 are mufflers. The air cylinder 33 used in this embodiment is a so-called end lock cylinder provided with a holding mechanism that can hold the cylinder rod 33a at the raised position. The remaining structure except for the pneumatic circuit and the like is substantially the same as that of the third embodiment, except that the mechanical valve 22 provided on the engagement plate 17 is replaced with that of the first embodiment shown in FIG. Is provided with a limit switch 18.

In this embodiment, when the feeder bank 11 is installed in the supply section M1 of the mounting apparatus M, the limit switch 1 provided on the engagement plate 17 is provided similarly to the first embodiment.
8 outputs a detection signal, and the electromagnetic valve 30 is turned on in accordance with the detection signal. As a result, the air supply source 20
Is sent from the ON-side block of the electromagnetic valve 30 to the projecting space of the air cylinder 33 via the speed controller 32 as shown in the figure, and raises the cylinder rod 33a. As a result, the feeder bank 11 is raised, and the engagement protrusion 11a is engaged with the engagement hole 17a of the engagement plate 17, and is fixed at a fixed position.

In this state, the cylinder rod 33a is held by the holding mechanism provided on the air cylinder 33. Therefore, even if air is shut off or leaks in the air supply source 20, the feeder bank 11 is raised by the cylinder rod. The position is maintained and the state of engagement with the engagement plate 17 is not inadvertently released, and the same effects as those of the above embodiments can be obtained. When removing the feeder bank 11 from the supply section M1 of the mounting apparatus M, the holding mechanism of the cylinder rod 33a may be released and the cylinder rod 33a may be pressed down, and the removal operation can be performed extremely easily.

In each of the above embodiments, the case where the elevating mechanism of the feeder bank 11 is provided in the supply section M1 of the mounting apparatus has been described as an example. However, the elevating mechanism can be attached to the carrier 10 or the like. In this case, however, a plurality of elevating mechanisms must be provided together with each caster, and the entire apparatus becomes expensive. However, the intended purpose can be sufficiently achieved, and the technical idea of the present invention is limited to the above-described embodiment. It is not something to be done.

In each of the above embodiments, the supply unit M1 of the mounting apparatus M may be provided at one position with respect to the mounting position of the circuit board B, or may be provided at two positions in a direction crossing the circuit board moving direction. May be. When the supply unit M1 is provided at two locations on the front side and the rear side opposite to the mounting position, when the electronic component supply unit on the rear side is replaced while the electronic component on the front side is mounted, the front side and the rear side are replaced. Even if the electronic components disappear and the mounting head moves rearward, there is no fear that the mounting head will be damaged. Therefore, there is no need to stop the electronic component mounting work,
Productivity can be improved.

When the electronic components in the front component supply unit are exhausted, the electronic components are supplied from the rear component supply unit, and during this time, the feeder bank of the front component supply unit is filled with predetermined electronic components. It can be exchanged for a feeder bank. Therefore, the mounting operation of the electronic component mounting apparatus can be continuously performed without stopping, and the operation efficiency is significantly improved. In addition, there is provided an elevating mechanism which can move the feeder bank to an initial setting position and a component supply position provided above the initial setting position.
An engagement means is provided for preventing the feeder bank from moving in the horizontal direction when the dust bank moves from the initial setting position to the component supply position.
