Referring to the operation and effect of the present invention.

When the operator places the plurality of stacked empty trays 2 on the entry conveyor 50, the tray 2 is transported by the entry conveyor 50, and then the sensor 51 which detects the entry completion of the tray 2 is carried out. When the entry stoppers 53 and 54 protrude by the 52, the transfer of the tray 2 is suppressed and the entry cylinder 57 is operated to raise the entry plate 55 and 56. While raising the bottom of the tray (2) to separate the stacked tray (2) from the entry conveyor 50 to wait for the tray (2).

The waiting tray 2 is operated by the cylinder operating sensors 23 and 24 to detect the completion of the cracking process of the cracking section conveyor 20 so that the entry cylinder 57 is operated so that the entry ramp 55 As the 56 is lowered, the tray 2 is seated on the entrance part conveyor 50 and is conveyed to the slow decomposition part conveyor 20 side.

The tray 2 conveyed to the unit part conveyor 20 is transported by the unit part stoppers 25 and 26 by arrival detection sensors 21 and 22 which sense the arrival of the unit part conveyor 20. At the same time as the tray 2 is stopped, the tray disconnecting device 70 is operated to grasp the upper ends of the lowermost tray 2 with the catch 82 to lift the entire stacked tray 2 and then lower the lower tray. (2) is sequentially supplied to the tape storage conveyor (10).

In the process of sequentially disassembling the tray 2, as shown in FIGS. 6A and 6B, the linkage 76 descends while the cylinder device 69 is pulled down so that the disassembly table 78 is removed. When lowering, the bracket (86) and the rotating shaft 81 and the fixing bracket (87) and the locking portion (89) (90) of the rotating bracket 88 of the distal end 78 of the disengaged table 78 is engaged with each other, that is, 82 is lowered in the state which caught the lowest tray 2 among the trays 2 which were stacked.

At this time, the vertical separation stage 78 vertically installed with the rail 84 is supported by the vertical reciprocating motion by the liner bearing 83 fixed to the frame 85.

When the lowermost tray 2 is placed on the conveyor, the hanger 82 holding the tray 2 as the first roller 94 slides outward along the inclined surface of the first cam 93 is removed from the tray 2. (The state in the example of FIG. 6 (a)), the locking stand 82 is lowered by the remaining stroke of the cylinder 75 in a state of being rotated in a clockwise direction, and again, as the advancing stage of the cylinder 75 As the 78 rises, the hanger 82 also rises.

Here, the operation (virtual line indicates the operating state) of FIG. 6 (a) will be described in detail. When the first roller 94 slides out along the inclined surface of the first cam 93, the rotating bracket ( 88 is rotated in the direction of the arrow (a) shown in Fig. 6, while the locking hole 90 of the rotating bracket 88 is separated from the locking hole 89 of the fixing bracket 87 to fix the bracket (87) Is rotated in the direction of the arrow (b) by the elastic force of the spring 92 so that the hanging bracket 82 is rotated in the clockwise direction to open, and the rotating bracket 88 is separated from the locking hole (89) of the fixing bracket 87 The spring 91 pushes the bottom of the locking hole 89 of the fixing bracket 87 again by the elastic force of the spring 91 so as to maintain the opening 82.

When the separation unit 78 is raised by the cylinder device 69 (virtual line indicates an operating state), the second roller ( 96 slides along the inclined surface of the second cam 95, and the catch 82 is inserted into both sides of the second tray 2, and ascends while holding the tray 2 (example of FIG. 6 (b) condition).

Here, when the second roller 96 slides the inside of the conveyor along the inclined surface of the second cam 95 and rotates the fixing bracket 87 to the inside of the conveyor, the bottom of the fixing bracket 87 rotates the rotating bracket 88. Rotate while pushing.

At this time, the rotation bracket 88 is forcibly pushed in the opposite direction to the elastic force of the spring 91, the locking bracket (89) and the locking bracket (90) of the locking bracket (90) when the fixing brackets meet By the restoring force of the spring 92 of the 87 and the spring 91 of the rotary bracket 88, the locking hole 89 of the fixed bracket 87 and the locking hole 90 of the rotary bracket 88 are coupled They are raised while being engaged with each other while maintaining elastic force.

That is, the tray 2 at the lowermost end is lifted by holding the side of the second tray 2 while leaving it on the conveyor, and the remaining tray 2 presses the tray 2 at the second height to operate the cylinder 75. The stoppers 25 and 26 are released by the operation sensors 23 and 24 and are transferred to the tape storage conveyor 10.

One tray 2 conveyed to the tape storage conveyor 10 stores the tape 1 in the tray 2 according to the normal process of the chuck unit, and the stored tray 2 is stored in a known conveying process. Therefore, it passes through the connection conveyor 60, and is conveyed on the stepped conveyor 40.

Here, although there is no prior tray 2 on the stack | conveyor part conveyor 40, it demonstrates on the assumption that the prior tray 2 was piled up by a predetermined amount.

When the tray 2 arrives on the stack conveyor 40, the stack stoppers 45 and 46, which are operated by the sensors 41 and 42 that sense arrival, stop the tray 2 being transported once. The process of sequentially stacking the tray 2 is the same as the cylinder device 69 of the tray cracking device 70, as shown in FIGS. 7A and 7B. As the link 176 is lowered and the lower stage 178 is lowered while being pulled down, the hanger 182 is lowered.

In addition, the tray 2 in which a certain amount of tapes hung on the hanger 182 is stored is stacked on the tray 2 on the conveyor.

At this time, as the first roller 194 slides outward along the inclined surface of the first cam 193, the hanger 182 holding the tray 2 is released from the tray 2 (see FIG. 7A) ), The locking stand 182 is lowered by the remaining stroke of the cylinder 175 in the open state.

Here, while the rotating bracket 188 rotates in the direction of the arrow (C), the locking hole 190 of the rotating bracket 188 leaves the locking hole 189 of the fixing bracket 187, and the fixing bracket 187 is a spring ( Rotating bracket 188 is rotated in the direction of the arrow (d) by the elastic force of the 192 to open and the locking bracket 188 is separated from the locking hole 189 of the fixing bracket 187 by the elastic force of the spring 191. The bottom of the locking hole 189 of the fixing bracket 187 is pushed to keep the locking stand 182 in the open state.

At this time, the second cam 195 is lowered together with the second roller 196 while the stage 178 is lowered to be in contact with the angular surface, not the inclined surface of the second cam 195, the spring 199 and the second Since the elastic force acts so that the second cam 195 always comes into close contact with the second stopper 198 by the stopper 198, the second roller 196 descends while pushing the second cam 195 while pushing. After the excess, the second cam 195 is restored again by the elastic force of the spring 199.

As the step 178 rises as the cylinder 175 moves forward, the hanger 182 rises.

When the latch 182 rises in the open state and comes to the position of the lowermost tray 2, the second roller 196 slides along the inclined surface of the second cam 195, and the latches 182 are both sides of the lowermost tray 2. The tray 2 is held while being inserted in the state (the state of FIG. 7 (b)).

Here, the second roller 196 slides the inside of the conveyor along the inclined surface of the second cam 195 and pushes the fixing bracket 187 outward to the conveyor, thereby restoring force by the spring 191 of the rotating bracket 188. As a result, the locking holes 189 of the fixing bracket 187 and the locking holes 190 of the rotating bracket 188 are coupled to each other and are maintained while maintaining the elastic force.

At this time, the first cam 193 is raised together with the first roller 194 while the stacking stage 178 is raised to be brought into contact with the angular surface rather than the inclined surface of the first cam 193. The first cam 193 has its own weight. Is hinged while being supported by the first stopper 197, so that the first roller 194 can be pushed up while pushing the first cam 193, and after passing, the first cam 193 Return to position by self weight

That is, the hanger 182 is raised by holding the side of the lowermost tray (2) on the conveyor to complete the step of stacking the tray (2).
