Reference numeral 17 denotes a discharge cylinder, which causes the case supply cylinders 15 and 16 to retreat from the outlet 3a of the hopper 3, thereby causing all the cases 4 in the hopper 3 to fall. This discharge cylinder 17 is connected to the type of case 4 in the hopper 3 (the length of the case varies depending on the number of batteries. It is activated when changing the number of batteries. 18 is connected to the printing section 10.1). In the printing section 10.1), the product number, company name, etc. are printed on the surface of the case 4, and then the case 4 is dried. 19 is when case 4 with assembled batteries is released to the general public! This is Debe.

Next, details of each component will be explained with reference to FIG. 3 and subsequent figures.

First, the structure of the assembled battery arrangement section 2 will be explained with reference to FIGS. 3 to 6. Reference numerals 21 to 25 are chucks for picking up batteries, and five sets of chucks are arranged in accordance with the number of batteries. 26.2
Reference numeral 7 denotes a chuck plate, each of which has a piston 30 .
It is equipped with 31. Moreover, each chuck plate 26, 27 is
It is provided with sliding guide bars 33, 34 arranged within the chuck case 28. FIG. 4 shows a state in which the chuck 25 is closed, and from this state the cylinder 29
When air pressure is applied between the pistons 30, 31 inside, the pistons 30, 31 move away from each other, and the chuck plates 26, 27 are separated accordingly, and the chuck 25 is in the open state (state shown by imaginary line). . The movement is the guide bar 33
．． Supported by 34. Also, conversely, the piston 30.
When air pressure is applied from the outside of piston 30.
31 move toward each other and the chuck 25 closes. The same applies to other chucks. Reference numeral 35 denotes a bearing case, which contains a bearing for supporting a gear shaft 36 erected on the chucks 21 to 25. Bearing case 3
5, feed shafts 37, 38 are slidably inserted therethrough. Both ends of the feed shaft 37, 38 are fixed to end walls 44, 45 of a rotary frame 39 that covers the chucks 21-25. 42 and 43 are racks fixed to the side walls of the rotating frame 39 on different sides. Chuck 21.22.2
At the upper end of the gear shaft 36 of 4.25, gears 46 to 49 are installed, each meshing with one of the racks 42.43. The gears 46-49 are arranged alternately on different sides of the rack 42.
43, and the outer gear 46.49
Make the diameter larger than the inner gear 47.48. That is, the large diameter gears 46 and 49 are made to mesh with the rack 42, and the inner gears 47 and 48 are made to mesh with the rack 43. A spring 50 is attached to the upper end of the gear shaft 36 of the center shaft 23.

This spring 50 is for reversing and returning the chuck 23 which has rotated 90 degrees as will be described later.

Reference numeral 51 denotes an index plate, which is oscillated and rotated by a rotary actuator 52 installed on the rotating frame 39. One end of a long screw arm 53.54 is pivotally attached to both ends of the index plate 51, and one end of a short screw arm 55,56 is pivotally attached to the inside of the index plate 51 via a spacer stand 57 (see FIGS. 5 and 5). (See Figure 6)

Then, the other ends of each of the long screw arms 53.54 and the short screw arms 55.56 are rotated along the rack 42° to the rack 43 via the gears 46, 49, 47, 48 that are pivotally supported thereon. Move on the same line so that it spreads outward. In this case, since the lengths of the outer and inner screw arms and the distance from the pivot point of both to the index plate 51 to the rotation axis of the index plate 51 are different, the long screw arm 53 and the short screw arm 55,
In addition, the distance between the long screw arm 54 and the short screw arm 56 becomes wider than originally, and even if the batteries that are lined up side by side rotate, they no longer come into contact with each other.

Further, with this isolation operation, the gears 46 and 49 that mesh with the rack 42 rotate in the same direction, and the gears 47 and 48 that mesh with the duck 43 on the opposite side rotate in the opposite direction to the gears 46 and 49. Therefore, the two adjacent chucks of each chuck 21 to 25 rotate in opposite directions while being separated from each other. At this time, the middle battery chucked by the chuck 23 is pulled and rotated by the batteries connected via leads on both sides. As a result, the batteries, which were lined up side by side in opposite directions, are rearranged vertically and in the same orientation. Note that the chart 23 may be provided with a separate cylinder (fixed to either rack 42, 43) and driven to rotate in the opposite direction.

Therefore, when the air inside the vacuum pad 86 is removed and nesting is performed, the case 4 is attracted. Then, the lifting cylinder 84 raises the LM ice ball attached plate 88 and lifts the case 4 from the ice conveyor 13, and then the rodless cylinder 82 operates and moves the suction unit to the standby position while sucking the case 4. The case 4 is moved to a position where the battery is inserted into the case 4, and the elevating cylinder 84 is lowered to place the case 4 on the stationary pedestal 91a. Then, the rodless cylinder 5a is used to pack the battery, but during this time the case 4 continues to be attracted and held in that position with the illuminating surface. Note that after that, the cases 4 are conveyed one after another on the stationary cradle 91a by the conveyance pedestal 91. That is, a plurality of conveyance pedestals 91 are arranged at regular intervals, and are given an expanded elliptical movement by a cam mechanism 122 shown in FIG. On the other hand, the stationary pedestals 91a are installed on the base plate 123 at regular intervals, and slits are provided in the base plate 123 and the stationary pedestals 91a. Then, the general feed pedestal 91 moves between these slits, and by the action of the cam mechanism 122, when it goes up after retreating, it receives the case 4 from the stationary cradle 91a and floats it up, and when it goes down after moving forward, it receives the case 4. remains on the previous stationary pedestal 91a. Due to such an operation of the transfer stand 91, the case 4
will be transported one after another.
