However, since the buffer device described in Patent Document 1 is a type that only stores a large amount of fastener chains, the size thereof is large, and the fastener chain processing device has been enlarged.

The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a fastener chain buffer device capable of downsizing the fastener chain processing device.

The above object of the present invention can be achieved by the following constitution.

Hereinafter, an embodiment of a fastener chain buffer device according to the present invention will be described in detail with reference to the drawings. In the following description, regarding the fastener chain processing device and the buffer device, the upper side is the upper side of the paper surface of FIG. 1, the lower side is the lower side of the paper surface of FIG. 1, and the left side is the paper surface of FIG. The front side and the right side are the back side with respect to the paper surface of FIG. 1, the front side is the left side with respect to the paper surface of FIG. 1, and the rear side is the right side with respect to the paper surface of FIG. The front side is also called the upstream side, and the rear side is also called the downstream side. The left-right direction is also called the width direction.

First, as shown in FIG. 1, the fastener chain processing apparatus PM includes a plurality of processing apparatuses along the conveying direction of the fastener chain. According to the embodiment, the fastener chain processing apparatus PM has three processing apparatuses. That is, the fastener chain processing apparatus PM includes a first processing apparatus M1, a second processing apparatus M2, and a third processing apparatus M3 in order from the upstream side in the conveyance direction of the fastener chain C. The first to third processing devices M1 to M3 are disposed on the base BT.

The fastener chain processing apparatus PM includes a buffer device that stores the fastener chain between the plurality of processing apparatuses. According to the embodiment, the fastener chain processing apparatus PM includes the first buffer device 10A that stores the fastener chain C between the first and second processing apparatuses M1 and M2. The fastener chain processing apparatus PM includes a second buffer apparatus 10B that stores the fastener chain C between the second and third processing apparatuses M2 and M3.

The cycle time of the first processing device M1 is 1.5 seconds. The cycle time of the second processing apparatus M2 is 2.0 seconds. The cycle time of the third processing device M3 is 2.5 seconds. The cycle time is a processing time for one time for the fastener chain C in each of the processing apparatuses M1 to M3.

For this reason, the third processing apparatus M3 is always driven. Then, the second machining device M2 having the second slowest cycle time is intermittently driven in accordance with the driving of the third machining device M3 having the slowest cycle time. The first machining device M1 having the fastest cycle time is intermittently driven in accordance with the driving of the second machining device M2 having the second slowest cycle time.

The first buffer device 10A monitors the storage amount of the fastener chain C stored between the first and second processing devices M1 and M2, and controls the drive interval of the first processing device M1. The second buffer device 10B monitors the storage amount of the fastener chain C stored between the second and third processing devices M2 and M3, and controls the driving interval of the second processing device M2. The first and

second buffer devices

10A and 10B are devices having the same structure.

As shown in FIGS. 2 to 4, the first buffer device 10A is disposed below the first processing device M1. Further, the second buffer device 10B is arranged below the second processing device M2. Each of the

buffer devices

10A and 10B is provided with a base portion 11 attached to the lower surface of the base BT, an arm 12 supported by the base portion 11 so as to be swingable in the vertical direction, and rotatably provided at a distal end portion of the arm 12. The roller 13 for guiding the fastener chain C, the upper limit sensor 14 for detecting the upper limit swing position of the arm 12, the lower limit sensor 15 for detecting the lower limit swing position of the arm 12, and the arm 12 from the lower limit swing position. And a stopper 16 for restricting the downward swing of the arm 12 so as not to swing downward.

The roller 13 of the first buffer device 10A is disposed between the first and second processing devices M1 and M2, and the roller 13 of the second buffer device 10B is disposed between the second and third processing devices M2 and M3. Has been.

Further, the upper limit sensor 14 and the lower limit sensor 15 are fixed to the base portion 11. These

sensors

14 and 15 are preferably non-contact sensors such as photoelectric sensors and proximity sensors. The stopper 16 protrudes from the base portion 11 and is disposed so as to face the lower surface of the arm 12.

Note that reference numerals 21 to 24 in FIG. 1 denote guide rollers that guide the conveyance of the fastener chain C. A pair of guide rollers are disposed above the one roller 13 and are disposed upstream and downstream in the transport direction. The roller 13 presses the fastener chain C downward. Accordingly, the fastener chain C is curved in a U shape downwardly between the pair of guide rollers.

Reference numerals 25 to 27 denote feed devices for transferring the fastener chain C in the first to third processing devices M1 to M3. The feed device has a drive roller that is rotated by a motor (not shown) and a press roller that presses the fastener chain C toward the drive roller.

In the fastener chain processing apparatus PM configured in this way, the first processing apparatus M1 has a faster cycle time than the second processing apparatus M2, so the first and second processing apparatuses M1 and M2 process the fastener chain C. When it does, the storage amount of the fastener chain C between the 1st and 2nd processing apparatuses M1 and M2 increases. As a result, the arm 12 of the first buffer device 10A swings downward (see FIG. 4). When the arm 12 is detected by the lower limit sensor 15, the storage amount becomes maximum, and the processing of the first processing device M1 is stopped. On the other hand, the processing of the second processing apparatus M2 is continued.

Furthermore, the fastener chain processing apparatus PM is stored between the first and second processing apparatuses M1 and M2 when the second processing apparatus M2 processes the fastener chain C while the processing of the first processing apparatus M1 is stopped. The fastener chain C is transferred to the downstream side, and the storage amount of the fastener chain C is reduced. As a result, the arm 12 of the first buffer device 10A swings upward (see FIG. 3). When the arm 12 is detected by the upper limit sensor 14, the storage amount is minimized, and the machining of the first machining apparatus M1 is resumed.

Further, in the fastener chain processing apparatus PM, since the cycle time of the second processing apparatus M2 is faster than that of the third processing apparatus M3, when the second and third processing apparatuses M2 and M3 process the fastener chain C, The amount of storage of the fastener chain C between the second and third processing devices M2 and M3 increases. As a result, the arm 12 of the second buffer device 10B swings downward (see FIG. 4). When the arm 12 is detected by the lower limit sensor 15, the storage amount becomes maximum, and the processing of the second processing device M2 is stopped. On the other hand, the processing of the third processing device M3 is continued.

Furthermore, the fastener chain processing apparatus PM is stored between the second and third processing apparatuses M2 and M3 when the third processing apparatus M3 processes the fastener chain C while the processing of the second processing apparatus M1 is stopped. The fastener chain C is transferred to the downstream side, and the storage amount of the fastener chain C is reduced. As a result, the arm 12 of the second buffer device 10B swings upward (see FIG. 3). When the arm 12 is detected by the upper limit sensor 14, the storage amount is minimized, and the machining of the second machining apparatus M2 is resumed.

Since the first to third processing devices M1 to M3 sequentially process one fastener chain C, finally, the first to third processing devices M1 to M3 are arranged in accordance with the driving of the third processing device M3 having the slowest cycle time. And 2nd processing apparatus M1, M2 will be driven intermittently.

buffer devices

10A and 10B of the present embodiment, the base portion 11 disposed below the processing devices M1 and M2, and the arm supported by the base portion 11 so as to be swingable in the vertical direction. 12 and a roller 13 rotatably provided at the distal end portion of the arm 12 and guiding the fastener chain C, and the roller 13 is disposed between the plurality of processing devices M1 to M3. The fastener chain C can be stored in a space configuration, and thus the fastener chain processing apparatus PM can be reduced in size.

Further, according to the

buffer devices

10A and 10B of the present embodiment, since the upper limit sensor 14 that detects the upper limit swing position of the arm 12 and the lower limit sensor 15 that detects the lower limit swing position of the arm 12 are provided, a fastener is provided. The storage amount of the chain C can be easily detected, and the plurality of processing devices M1 to M3 can be driven efficiently.

Further, according to the

buffer devices

10A and 10B of this embodiment, since the arm 16 is provided with the stopper 16 that restricts the downward swing of the arm 12, the arm 12 swings downward too much and the roller 13 is placed on the floor surface or the like. Contact can be prevented.
