The conveyor chain table is driven by a drive source (not shown). In the conventional device having the above configuration, the bottle conveyed on the conveyor chain table 12 is conveyed along the shape of the guide rail 10 with the bottom supported by the flight bar 11.
It is designed to be supplied to carrier 2.

The above conventional device is (i) conveyor chain table 12 of bottle feeding device 5.
When there are fewer bottles on the top, before the bottle approaches the guide rail 10 sufficiently, the bottom of the bottle is lifted by the flight bar 11 to the side opposite to the guide rail 10, causing the bottle to overturn. As a result, the machine stops due to the activation of a safety device (not shown), takes time to recover, and reduces the operating rate.

(ii) In order to prevent the drawback of (i) above, when the number of bottles on the conveyor chain table 12 becomes small,
If the machine is stopped until the amount has recovered properly,
This may cause an abnormality in the flow of the line after the bottle washer. Additionally, since the bottles are immersed in high-temperature caustic liquid for a long time while the machine is stopped, this has a large effect on the bottles.

(iii) At the end of the operation, all the bottles in the bottle washing machine need to be discharged, so the supply of bottles to carrier 2 is stopped, but it is necessary to empty the bottles on the conveyor chain table. be. Therefore, at the start of operation, it is necessary to take measures to place the appropriate amount of bottles on the conveyor chain table.

(iii) In order to prevent the drawback of (i) above and implement the operating methods of (ii) and (iii) above, it is necessary to place an operator in the bottle feeding device section.

There were drawbacks such as:

The present invention was proposed with the aim of eliminating the drawbacks of the conventional devices described above, and includes a bottle feeder that is driven synchronously with the carrier and supplies bottles into the carrier of a machine equipped with a carrier for conveying bottles. The present invention relates to a bottle feeding device, characterized in that a drive section of the bottle feeding device is provided with a driving force intermittent device that operates by detecting the state of supply of bottles to the bottle feeding device.

Hereinafter, according to the embodiments shown in FIGS. 2 to 4,
The present invention will be explained in detail.

In these figures, 6 is a main shaft rotatably provided in the bottle feeding device 5 as shown in FIG. 1, and the main shaft 6 has the same structure and function as that of the conventional device described above. . (The same symbols are attached.)1
A sprocket 4 corresponds to the sprocket 7 of the conventional device, and the sprocket 14 has one pin hole 14a bored in a proper position on the inner surface thereof. 17
is a boss fixed to the main shaft 6 via a key 18,
The sprocket 14 is loosely fitted onto the outer periphery of the boss 17 while being held by a collar 26. 1
5 is a disc with a pin 16 protruding from an appropriate position on the outer wall, which engages with the pin hole 14a of the sprocket 14;
The disk 15 is held slidably in the axial direction by the main shaft 6 through its center hole, and has a groove 15a on its outer peripheral end surface that engages with the tip of a lever to be described later.
is provided. A fluid pressure cylinder 19 is held in the machine frame 29 and is interlocked with a sensor (not shown). Reference numeral 21 denotes a rotating shaft whose both ends are rotatably supported by a machine frame 29, and 20 and 22 indicate a pair of levers whose lower ends are attached to the rotating shaft 21. At the upper ends of each of the levers 20 and 22, Groove 1 of the disk 15 above
An engaging portion 23 that engages with the portion 5a is provided. 2
4 is a compression spring that urges the disk 15 toward the sprocket 14; 28 is an arm whose one end is fixed to the rotating shaft 21; and a tension spring is provided between the hook 27 at the other end of the arm 28 and the machine frame 29. 25 is tensioned, and the tension spring 25 is connected to the arm 28 and the rotating shaft 21.
The levers 20 and 22 are biased upward through the levers 20 and 22. And the carrier 2 shown in Figure 1
The boss 17 is rotated via the pin 16 of the disc 15 fitted into the pin hole 14a of the sprocket 14 driven by the roller chain 4 which drives the bottle feeding device 5 which supplies bottles in synchronization with the boss 1.
7 causes the main shaft 6 to be driven and rotated via the key 18. Furthermore, the rotation of the main shaft 6 drives the sprocket 8 shown in FIG.
The bottles on 2 are adapted to be fed to carrier 2. In this case, conveyor chain table 1
When a sensor (not shown) detects that the amount of the bottle on the top 2 (see FIG. 1) has decreased, the fluid pressure cylinder 19 is actuated by that signal, and the arm 28 is pushed up against the tension spring 25, causing the lever 20 to move upward. The lever 22 is tilted to the left via the rotating shaft 21, as shown in FIG. 4, and the disk 15 is moved to the left along the main shaft 6 against the compression spring 24.
As a result, the pin 16 that had been fitted into the pin hole 14a of the sprocket 14 is pulled out from the pin hole 14a, the sprocket 14 idles on the outer periphery of the boss 17, and the drive of the main shaft 6 via the roller chain 4 is cut off. It's starting to become easier. Therefore, the sprocket 8, endless roller chain 9, and flight bar 11 (see FIG. 1) attached to the main shaft 6 are not driven, and bottles are not supplied to the carrier 2. On the other hand, the conveyor chain table 12 is continuously driven by a drive source (not shown).
(See Figure 1) When the upper bottle reaches the appropriate level, a sensor (not shown) senses this, and the signal causes the fluid pressure cylinder 19 to operate in the opposite manner to the above case.
is pushed back by the compression spring 24, the pin 16 fits into the pin hole 14a, and the levers 20, 2
2 is also returned to its normal position by the action of the tension spring 25, and as a result, the endless roller chain 9 and the flight bar 11 are driven in a position synchronized with the movement of the carrier 2, resulting in a normal operating state, and the bottle is It is now being supplied to Carrier 2.

A sprocket 14 having the pin hole 14a, a disk 15 having an engaging groove 15a and a pin 16 on the outer peripheral end surface, a boss 17 fixed to the main shaft 6 with a key 18, a hydraulic cylinder operated by a sensor signal, a lever 20, 22, rotating shaft 21, compression spring 2
4. The tension spring 25, the arm 28, and the like form a driving force intermittent device that is installed in the drive section of the bottle feeding device and operates by detecting the state of bottle supply to the bottle feeding device.

One embodiment of the device of the present invention is constructed as described above, and when the device starts operating, if there is an appropriate amount of bottles on the conveyor chain table 12, the fluid pressure is detected by a detection signal from a sensor (not shown). The cylinder 19 is actuated, and the arm 2 is moved as shown in FIG.
8. Pin 16 of disk 15 via levers 20 and 22
is fitted into the pin hole 14a of the sprocket 14, the driving force intermittent device is connected, and the driving force of the roller chain 4 is transmitted to the main shaft 6, so that the bottles on the conveyor chain table 12 are connected to the endless roller chain 9. It is supplied in synchronization with the movement of the carrier 2 while being guided by the guide bar 10 via the flight bar 11.

On the other hand, when the number of bottles on the conveyor chain table 12 decreases, a signal from a sensor detecting this causes the fluid pressure cylinder 19 to operate in the opposite manner to the above case, and the arm arm against the tension spring 25. 28 and rotate the rotating shaft 21 to release the lever 20,
22 and move the disk 15 to the left along the main shaft 6 against the compression spring 24 as shown in FIG. In order to disconnect the disconnection device, the main shaft 6 is not driven, so the endless chain 9 and the flight bar 11 are stopped, and bottles are not fed to the carrier 2.

Since the device of the present invention has the above-mentioned configuration and operation, according to the present invention, (1) When the number of bottles on the conveyor chain table of the bottle feeding device is low, a sensor detects the amount of bottles. is detected, the driving force interrupter is activated by the signal, and the driving force interrupter is in the "off" state, and the main shaft 6 does not rotate. Therefore, the entrestrial chain and flight bar stop and the bottle is not fed to the carrier, so the bottle is stopped. The flight bar lifts the bottom of the bottle before it approaches the guide rail, preventing the bottle from tipping over. Therefore, there is no need for the machine to stop due to the activation of a safety device, and there is no need for recovery time. The rate is significantly improved compared to before.

(2) Even when the drive intermittent device is activated and bottles are not fed to the carrier, the carrier continues to move through the bottle washer and discharge the bottles, so there is no abnormality in the flow of the line after the bottle washer. . Furthermore, since the bottle is not immersed in the high temperature caustic solution for a long time, there is no risk that the high temperature caustic solution will have an adverse effect on the bottle.

(3) At the end of operation, a separate signal activates the driving force intermittent device, which stops the supply of bottles to the carrier and allows all bottles in the bottle washer to be discharged. Furthermore, since a suitable amount of bottles remain on the conveyor chain table at the start of operation, operation can be started immediately.

(4) Due to (1) and (2) above, there is no need to always station an operator in the bottle feeding device.

The following practical effects can be mentioned.

In addition, as shown in the illustrated example, the limit switch 30
(a) When a variable speed motor is used as a motor for driving a bottle washing machine, it is possible to prevent contact with the limit switch 30 as shown in FIG. 4 while the driving force interrupter is operating. During this period, the drive is operated at low speed, and the driving force intermittent device is inoperative, that is, the limit switch 30 is operated at a low speed as shown in FIG.
However, it is also possible to operate at high speed when the vehicle is far away. Also, if a signal to return is issued,
In order to facilitate the return, the variable speed motor can be lowered to a low speed, and when the pin 16 is completely fitted into the pin hole 14a and the disk 15 is separated from the limit switch 30, the variable speed motor can be operated at a high speed.

(b) If the driving force intermittent device does not operate normally, it can also issue an abnormal signal or a signal to stop the entire machine including the bottle feeding device.

In the illustrated example, the main shaft 6 of the bottle feeding device rotates once while the carrier 2 moves one pitch, but the main shaft 6 rotates 1/2 turn while the carrier 2 moves one pitch. Alternatively, if it is desired to rotate by 1/3, etc., it is possible by providing two or three pin holes 14a. In addition, when it is desired to make the main shaft 6 rotate twice or three times while the carrier 2 moves one pitch, the period in which the pin 16 and the pin hole 14a should not be engaged can be electrically controlled by the This is possible if you do not allow it to return.

Furthermore, if the main shaft 6 of the bottle feeding device is divided in the center and the driving force intermittent device is installed on each side, bottles can be fed to half of the carriers, and bottles can be fed to the other half of the carriers. Operation without supply is also possible.
