Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holder circulation system, and more particularly, to a holder circulation system which circulates a holder and performs a required process on a container in the holder.

[0002]

2. Description of the Related Art Conventionally, as a holder transfer system, a transfer means for transferring a holder accommodating a container from an upstream side to a downstream side, and a transfer path of the transfer means are sequentially arranged, and a container in the holder is arranged. It is known to include a main machine that performs required processing, a plurality of slave machines, and a control device that causes the master machine and the plurality of slave machines to perform speed following operation. In such a conventional transfer system, the operating speed of the plurality of slaves is made to follow the operating speed of the main machine, and for example,
When the main machine is arranged on the most downstream side of the carrier path of the holder, each slave machine on the upstream side is operated in accordance with the operating speed of the main machine. Further, when the main machine is arranged in the middle of the carrier path of the holder, the operating speed of the slave machine located upstream of the main machine is matched with the operating speed of the main machine.

[0003]

By the way, as a circulatory transfer system for a holder, a main machine and a slave machine are provided at a plurality of points in a circulatory transfer path, and the holder is circulated and transferred between the main machine and the slave machine. There may be a demand for a system for performing the required processing on the container by the main machine and the slave machine. In this case, since a certain number of holders are circulated and conveyed, as in the above-described conventional case, simply by making the operating speed of the main machine follow the operating speed of the main machine, the holder is conveyed in the circulation transfer path. The distribution of the holders becomes uneven or uneven. In particular, such deviation of the distribution of the holders is likely to occur when the operating speed of the main engine is changed. Then, when the distribution state of the holders in the circulation conveyance path is biased or uneven, the main machine and the slave machines must be stopped. In view of such circumstances, it is an object of the present invention to provide a circulating carrier system for holders that can carry the holders in a uniform distribution state within the circulating carrier path.

[0004]

That is, according to the present invention, a main machine for carrying out a required process on a container in a holder, and a first carrying means for carrying the holder, which has finished processing of the container by the main machine, to a downstream side, A container discharge mechanism as a first slave that receives the holder from the first transfer means and takes out the container from the holder; and a second transfer means that transfers the holder from which the container has been taken out by the container discharge mechanism to the downstream side. A container supply mechanism as a second slave that receives the holder from the second transfer means and supplies the container into the holder, and transfers the holder to which the container is supplied by the container supply mechanism to the position of the main machine located on the downstream side. And a third transporting means, and an endless continuous circulation transport path is formed by the main machine, the first transporting means, the container discharging mechanism, the second transporting means, the container supplying mechanism, and the third transporting means. And a control device for speed-following operation of the main machine, the container discharge mechanism and the container supply mechanism, a transfer path of a third transfer means upstream from the main machine by a predetermined distance, and a predetermined distance from the container supply mechanism. Holders arranged on at least two of the transport path of the second transport means on the upstream side or the transport path of the first transport means on the upstream side by a predetermined distance from the container discharge mechanism, and each of which is preceded and followed by A plurality of pool amount detectors that detect the contact state and input to the control device are provided, and in the control device, the holder is in the contact state by any of the pool amount detectors. Provided is a circulating carrier system for a holder that controls the operating speed of a slave machine on the upstream side of the pool detector to be lower than the operating speed of a master machine or a slave machine on the downstream side when input. That.

[0005]

According to this structure, for example, when it is input to the control device that the holders which are in front of each other are brought into contact with each other by the accumulation amount detector provided on the upstream side of the first processing mechanism, The control device controls the operating speed of the second processing mechanism to be slower than the operating speed of the first processing mechanism. As a result, the contact state of the holders on the upstream side of the first processing mechanism is eliminated, and the holders can be circulated and conveyed in a uniform and uniform distribution state over the entire circulation conveyance path. Therefore, the holder can be smoothly circulated and circulated even in the circulatory conveyance path to perform the required processing.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to the illustrated embodiments. In FIG. 1, a circulation system 1 for holders comprises a filler / capper 2 as a main machine. The filler / capper 2 holds a holder 4 accommodating a flat plastic container 3 and rotates clockwise, and a predetermined amount of the container 3 in the holder 4 is provided on the first half side in the rotation region. After filling the filling liquid, a cap (not shown) is attached to the upper end opening of the container 3 on the latter half side in the rotation region. When the holder 4 holding the container 3 which has been filled with the filling liquid by the filler / capper 2 and attached with the cap is discharged onto the first conveying means 5 composed of a conveyor, this is indicated by an arrow by the first conveying means 5. After being sequentially conveyed to the downstream side as described above, it is supplied to the container discharge mechanism 6 as the first slave. When the container discharging mechanism 6 receives the holder 4 from the first conveying means 5, the container 3 is taken out of the holder 4 in the process of holding the holder 4 and rotationally transferring it in the clockwise direction, and discharges the container 3 from the conveyor. On the other hand, the emptied holder 4 is discharged onto the second conveying means 8 composed of a conveyor while being discharged onto the second conveying means 7. After that, the empty holders 4 on the second transfer means 8 are sequentially transferred toward the downstream side and are supplied to the container supply mechanism 11 as the second slave. In the process in which the container supply mechanism 11 is rotated counterclockwise, first, the supply conveyor 1
2 receives an empty container 3 from above, and then stores the container 3 in an empty holder 4 received from the second transfer means 8, and thereafter, the third transfer means 1 comprising a conveyor.
The holder 4 containing the container 3 on the top 3 is discharged. The third transporting means 13 is configured to sequentially transport the holder 4 containing the empty container 3 to the downstream side, and then to supply it to the filler / capper 2 as the main machine described above. In this embodiment, the filler and capper 2 as the main engine, the first
The conveying means 5, the container discharge mechanism mechanism 6 as the first slave, the second conveyor means, the container supply mechanism 11 as the second slave, and the third conveyor means 13 constitute an endless continuous circulation conveyor path 14. A predetermined number of holders 4 are circulated and conveyed in the circulatory conveying path 14 in the arrow direction. As shown in FIG. 2, the filler / capper 2, the first transfer means 5, the container discharge mechanism 6, the second transfer means 8, the container supply mechanism 11, and the third transfer means 13 that constitute the circulation transfer path 14, The motor 15 is provided as a drive source, and the operation of each of these motors is controlled by the controller 16. Further, an operating speed detector 17 is interlocked with the filler / capper 2 as the main engine, and the operating speed detector 17 is operated by a motor 15 which is a drive source of the filler / capper 2 by a control device 16. The operating speed during the operation is detected and input to the control device 16. Then, by transmitting the required operating speed command from the control device 16 to the drive circuit 15 ′ of the motor 15 of the filler / capper 2, the filler / capper 2 can be operated at the required operating speed. At that time, the operating speed of the filler / capper 2 is input to the control device 16 by the operating speed detector 17, and if, for example,
Filler and capper 2 input from operating speed detector 17
If the operating speed of the motor is not the speed corresponding to the initially transmitted operating speed command, the operating speed command is transmitted again to the drive circuit 15 ′ of the motor 15 so as to become the operating speed corresponding to the initially transmitted operating speed command. I am trying to do it.
Further, when the control device 16 operates the filler / capper 2 as described above, the drive circuit 15 ′ of each motor 15 of each of the other devices forming the circulating transfer path 14 is operated.
The operating speed command is simultaneously transmitted to the speed setter 15 ″ provided in the above. As a result, the first transport means 5, the container discharge mechanism 6, the second transport means 8, the container supply mechanism 11 and the third transport means
The transporting means 13 is designed to operate following the operating speed of the filler / capper 2. Therefore, in the present embodiment, on the premise of the above-mentioned configuration, the circulation transport path 1
The holder 4 is improved so that the holder 4 can be conveyed in a uniform distribution state over the entire area. That is, the first accumulation amount detector 21 is provided on the transport path of the third transport means 13, which is located on the upstream side by a predetermined distance from the position of the filler / capper 2 as the master machine, and as the second slave machine. A second pool amount detector 22 is provided on the transport path of the second transport means 8 which is located on the upstream side by a predetermined distance from the position of the container supply mechanism 11. First pool amount detector 21 and second pool amount detector 2
When the holders 4 placed one behind the other in the conveying path provided with them are in contact with each other, 2 detects that and inputs it to the control device 16. In other words,
When the contact state of the holder 4 is detected by the first pool amount detector 21 or the second pool amount detector 22,
This means that the holder 4 is offset in the contact state on the transport path from the position where they are provided to the filler / capper 2 (container supply mechanism 11). In the present embodiment, when it is input from the first pool amount detector 21 that the holder 4 is in the abutting state when the filler / capper 2 as the main engine is operated at a predetermined operating speed. , That is,
Third transport means 1 immediately upstream of the filler / capper 2
When the holder 4 on the upper part 3 is abutted and offset, the control device 16 makes the operating speed of the container supply mechanism 11 on the upstream side of the filler / capper 2 slower than the operating speed of the filler / capper 2. To control. As a result, the deviation of the holder 4 on the third conveying means 13 located immediately upstream of the filler / capper 2 is eliminated, and the holder 4 in the abutting state is separated, and therefore, the circulation conveying path. The holder 4 can be transported in a uniform distribution state over the entire area of 14. On the other hand, when the fact that the holder 4 is in the contact state is input from the second pool amount detector 22 while the filler / capper 2 as the main engine is operating at a predetermined operating speed, that is, container supply When the holder 4 on the second conveying means 8 located immediately upstream of the mechanism 11 is biased to the abutting state, the control device 16 controls the container discharge mechanism 6 located upstream of the container supply mechanism 11. The operating speed is controlled to be slower than the operating speed of the container supply mechanism 11. As a result, the deviation of the holder 4 on the second transfer means 8 on the upstream side of the container supply mechanism 11 is eliminated, so that the holder 4 can be transferred in a uniform distribution state over the entire circulation transfer path 14. . As described above, according to the present embodiment, the holders 4 can be transported in a uniform distribution state in the entire area of the circulation transport path 14, so that the filler / capper 2 as the main machine, the container discharge mechanism 6 and the container as the slave machines. The supply of the holder 4 to the supply mechanism 11 is biased and the filler / capper 2, the container discharge mechanism 6 and the container supply mechanism 1
It is possible to prevent the operation of No. 1 from being stopped. Therefore,
The holder 4 can be smoothly circulated and conveyed in the circulation conveyance path 14 to perform the required processing on the container in the holder 4. Further, since the holders 4 can be conveyed in a uniform distribution state in the entire area of the circulation conveyance path 14 in this way,
It is not necessary to provide an accumulating section for absorbing the deviation or variation of the holders in the middle of the conveying paths of the respective conveying means 5, 8 and 13. Therefore, the total length of the circulation conveying path 14 can be shortened accordingly. it can. The control device 16 may be configured by a single main computer. In addition to the single main computer, a sub computer is installed in the filler / capper 2, the container discharge mechanism 6 and the container supply mechanism 11. Then, the control device 16 may be configured by the main computer and a plurality of sub-computers. In addition, the second accumulation amount detector 2
Instead of providing 2 on the transport path of the second transport means 8, the second pool amount detector 22 may be provided on the transport path of the first transport means 5 slightly upstream of the container discharge mechanism 6.
