Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an alignment mechanism for properly aligning a cast grid for a storage battery before sending it to the next process such as trimming.

This type of alignment mechanism consists of a flat plate-shaped pallet and a parallel conveyor, which are placed adjacent to a conveyor that horizontally conveys the lattice body released from the mold and placed above and below a horizontal axis perpendicular to the path of the lattice body. A bracket for supporting the pallet is attached, and the pallet is tilted until it is supported by a stop member of the main body of the apparatus in response to the pivoting of the bracket as the horizontal axis rotates. is slid down until it hits the abutting member formed at the tip of the bracket, and after adjusting the posture of the grid in this way, the bracket is further tilted and the abutting member at the tip is aligned with the surface of the pallet. It has been proposed so far that the grid body aligned as described above is fed into the next trimming process by retracting the grid body further downward.

However, the conventional alignment mechanism described above has a drawback in that when it slides down on the pallet and hits the contact member, the grid body bends and deforms due to the impact.

The present invention eliminates the above-mentioned drawbacks and provides a novel mechanism that can be applied to the alignment of many types of grid bodies, and will be described in detail below based on one embodiment.

First, to explain the symbols attached to the drawings, 1
2 is a conveyor belt for feeding the lattice body G into the alignment mechanism of the present invention; 3 is a guide plate attached to the frame 1 so as to be tiltable via a shaft 4 and its bearing 5; 6; Reference numerals refer to a plurality of aligning belts attached with a portion exposed above the guide plate 3, 7 and 8 a driving pulley and a driven pulley of the aligning belt 6, respectively, and 9 and 10 adjusting the tension of the aligning belt 6, respectively. A tension roll and a tension bolt, and an adjustment slit 12 provided between the driving pulley 7 and the driven pulley 8 and parallel to the upper part of the guide plate 3.
an adjustment roll movable above; 13 a shaft rotatably supported by a bearing 14 fixed to the end of the guide plate 3; 15 and 16 fixed to the shaft 13 and integrated with the shaft; The retaining plate and shaft lever 17 are springs 18 for keeping the retaining plate 15 in the vertical position when the guide plate 3 is in the horizontal position as shown in FIGS. 1 and 5.
19 is a long arm attached to one end of shafts 4 and 13, 20 is a short arm attached to the other end of shafts 4 and 13, and 20 is long arm 18.
21 is a long lever having a roller 23 at one end that is in sliding contact with the guide plate cam 22 and the other end is connected to the adjustment rod 20; 24 is a retaining plate cam 25; 27 is a camshaft, and 28 has a bifurcated portion 29 at its lower end that engages with the shot lever 24. A push-up rod 31 is attached to the frame 1 so as to be able to move up and down via a bracket 30, and 31 is a shot lever 2.
4 is the roller slidingly in contact with the upper green, 32 is the shaft 4
The sprockets 34 and 34' rotate through the idler sprocket 33 regardless of the
and 36' are upper and lower dies for trimming.

Next, the operation of the alignment mechanism of the present invention will be explained based on the drawings.

First, when the lattice body G separated from the mold is carried by the conveyor belt 2 shown in FIG. The body G is sent in approximately the same posture until it reaches the position shown by the solid line in the figure. Then, as time passes, the contact points between the grid body G and the plurality of alignment belts 6 gradually decrease, and as a result, the posture of the grid body G is gradually corrected as illustrated in FIG. Perfect alignment is achieved as shown in FIG.

The grid G on the guide plate 3 as described above
When the alignment of the roller 23 with the guide plate cam 22 moves from FIG. 1 to FIG. 3 as shown in FIG. 3, the long lever 21 tilts and the adjuster rod 20 moves upward. Therefore, the guide plate 3 is tilted downward as shown in FIG. 3 via the long arm 18 connected to the adjusting rod 20. Therefore, when the sliding position of the roller 26 with the holding plate cam 25 moves from the position shown in FIG. 3 to the position shown in FIG. via the shot lever 24
As the push-up rod 28 slidingly contacts the shaft lever 16 and rotates the shaft 13, the holding plate 15 fixed to the shaft rotates and is guided as shown in FIG. Pull it in below the top surface of the plate 3. Then, the grid G that had been aligned on the guide plate 3 slides down in the same position and passes through the feed rolls 34 and 34' to the upper mold and lower mold 3.
It is trimmed into a predetermined shape by 6 and 36'. Note that after the lattice body G is separated from the guide plate 3 as described above, as the guide plate cam 22 and the retaining plate cam 25 rotate, the guide plate 3 and the retaining plate 15 return to their original states shown in FIG. return to the state.

According to the present invention, the posture of the grid body is corrected by the action of the plurality of alignment belts disposed on the guide plate as described above, so there is no possibility that the grid body will be deformed during correction as in the conventional case. In addition, the belt is equipped with an adjustment roll that allows the effective distance of the belt to be adjusted, so that it can accommodate various lengths of the cast grid body. The plates also have the advantage that they do not come off in the direction of travel and no external force is applied to the lattice body, and that they can be smoothly operated in a timely manner with the inclination of the guide plate using a completely novel drive mechanism.

The present invention, which has the above-mentioned advantages, can be applied to various alignment mechanisms for cast grid bodies, but is particularly suitable for matching grid bodies with weak mechanical strength or thin grid bodies.
