DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lining supply device and an adhesive applying device provided with the lining supply device.

[0002]

2. Description of the Related Art Conventionally, in the process of manufacturing a brake shoe for a drum brake, an arc-shaped lining is supplied one by one, an adhesive is applied to an inner peripheral surface thereof, and the lining is put into a drying furnace. And dry. In such an adhesive application device, a conventional lining supply device for supplying a lining one by one has a structure as shown in FIG.

In other words, a plurality of drum brake linings 50 are placed one on top of the other in a vertically upwardly convex position, and the other linings 50b except the one lining 50a are moved forward. Left and right locking plates 5
A magazine portion 51 locked and restrained by 1b and 51c;
The magazine 51 is disposed below the rear support plate 51d,
The magazine portion 51 includes a protruding plate 52 for projecting one lining 50a directly on the substrate 51a of the magazine portion 51 forward, and a cylinder device 53 for reciprocating the protruding plate 52 in the front-rear direction.

When the projecting plate 52 is moved forward (in the direction perpendicular to the plane of FIG. 9) by the cylinder device 53, one lining 50a directly mounted on the substrate 51a of the magazine 51 is moved. Is projected forward. After one lining 50a is protruded forward, the protruding plate 52 is returned to the rear, so that the next lining 50b falls on the substrate 51a by its own weight. The lining 50 protruding one after another is transferred to an adhesive ejection nozzle (not shown), and an adhesive is applied to the inner peripheral surface of the lining 50.

When the lining 50 is changed to a lining 50 having a different size, one of the locking plates 51b is adjusted to the left and right, and the rear support plate 51d is adjusted to the front and rear so that the new lining 50 is moved to the magazine portion. Closely housed in 51. In addition, even if the linings 50 have different sizes,
Since the thickness is almost the same, the projecting plate 52 is usually not changed.

[0006]

However, in such a conventional lining supply device, a single lining 50a is directly mounted on the substrate 51a of the magazine section 51 by a projection plate 52 having a predetermined thickness. The structure has a technical problem that the supply operation cannot be reliably obtained because of the structure in which the supply operation is performed by sequentially protruding forward. That is, when the linings 50 housed in the magazine portion 51 are displaced in the circumferential direction, the upper and lower linings 50a, 50a are protruded by the protruding plate 52 as shown in FIG.
b are integrally protruded, and the second lining 50b locked to the left and right locking plates 51b and 51c of the magazine 51 is damaged.

Therefore, one lining 50a at the lower end is provided.
When the thickness of the protruding plate 52 is reduced so that only the protruding portion is protruded, an excessive pressing force acts on a local portion of the lining 50a to be protruded, and the lining 50a is damaged. In particular, for the relatively soft lining 50,
The positioning and separation are difficult, and the above-mentioned damage is likely to occur.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional technical problem, and a lining supply device has a plurality of arc-shaped linings for a drum brake. And a magazine portion that holds the other lining except one lining at the lower end portion to restrain forward movement, and a front and rear position at the lower end portion of the magazine portion. provided by extending in a direction, the two support shafts for locking the two places in the circumferential direction of said plurality of linings, on the rear side of the lining to be locked to the support shaft, corresponding to each support shaft And a driving device for reciprocating the projecting member in the front-rear direction. In addition, the configuration of the adhesive coating apparatus is such that a plurality of arc-shaped drum brake linings are vertically stacked and accommodated in an upwardly convex posture, and other linings except one lining at the lower end are accommodated. A magazine portion that locks both ends in the circumferential direction to restrain forward movement, and a lower end portion of the magazine portion is provided extending in the front-rear direction, and two places in the circumferential direction of the plurality of linings are provided. Two supporting shafts to be locked, a projecting member disposed behind the lining to be engaged with the supporting shaft and projecting one lining directly engaged with the supporting shaft to project forward, and An adhesive applying device having a lining supply device having a driving device for reciprocating in a direction, wherein the adhesive applying device is disposed on the front side of the magazine portion, the tip portion is inclined downward, and the projecting member is used to move the adhesive coating device from the magazine portion. Sudden The conveyor has an endless belt for transferring the lining to be delivered in the left-right direction, and an endless belt which is disposed at a tip end of the conveyor in a vertical direction with a predetermined gap therebetween, and feeds the lining transferred as an upwardly convex posture downward. A belt feeder, a feed drive roller disposed opposite to the endless belt of the belt feeder and in contact with an inner peripheral surface of the lining fed downward, and a feed drive roller disposed below the feed drive roller, and An adhesive jet nozzle for applying an adhesive to a peripheral surface, and a guide roll for guiding an outer peripheral surface of the lining to which the adhesive is applied are provided.

[Action]

First, a plurality of linings are put into a magazine portion in an upwardly convex posture and locked on two support shafts. As for the lining put in the magazine part, only one lining at the lower end can move forward.
The forward movement of the other lining of the part is locked and restrained.

From this state, the lining supply device is driven. That is, if the protruding member is moved forward by the driving device, only one lining of the lower end portion directly locked to the support shaft is protruded by the protruding member arranged corresponding to each support shaft. You. If one lining is protruded, the protruding member is returned. The lining in the magazine portion is supplied one by one by repeatedly applying the forward and backward movements of the projecting member by the driving device in this manner.

Next, the subsequent operation of the adhesive application device provided with the above lining supply device will be described. The one lining protruded by the protruding member rides on the conveyor and starts moving, for example, to the right. The lining, which moves to the right by a conveyor whose tip is inclined downward, strikes the endless belt of the belt feeder. Since the endless belt feeds the lining downward, the endless belt starts descending while being fed by the feed drive roller on the inner peripheral surface. If the adhesive is ejected from the adhesive ejection nozzle, the adhesive is applied to the inner peripheral surface of the descending lining. The lowering of the lining is performed while the outer peripheral surface is guided by a guide roll, and the adhesive is uniformly applied to the inner peripheral surface of the lining which is almost in close contact with the adhesive jet nozzle.
The lining descending in this manner is guided by guide rolls while the outer peripheral surface is fed by the endless belt, and is fed by the inner peripheral surface by the feed drive roller, so that it takes a stable posture. The lining to which the adhesive has been applied is placed on a transfer conveyor in a downwardly convex posture, and is transferred to the next step.

In this way, the adhesive is applied one after another to the inner peripheral surfaces of the plurality of linings placed in the magazine portion. If the lining in the magazine is reduced, replenish the lining. Further, when changing to a lining having a different size, a storage space that matches the size of the lining after the change is formed in the magazine portion.

[0013] Even if the accommodation space of the magazine part formed in this way is too large and the lining is displaced in the circumferential direction, one of the lower end parts directly engaged with the two support shafts can be used. As long as the lining other than the lining is locked to the magazine portion and the forward movement is restricted, only one lining at the lower end can move forward. In this state, one lining at the lower end is reliably protruded forward by the protruding member, so that a supply mistake such as feeding in two linings is unlikely to occur.
