Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for inspecting the installation condition of a separable fitting of a slide fastener with a separable fitting.

Conventionally, when installing a slide fastener with a releasable insert, the condition of the releasable insert was determined by visual inspection based on the existence of the insert pin, box rod, and box, and the fact that there was little space between these rods, and therefore these rods were not close to each other. Inspect by checking that the points are close and parallel and that the notch created by the crimping to attach the rod and box to the fastener tape is deep enough and therefore the crimping is complete. It had been. Such manual inspection is not only inefficient but also impossible to accurately measure the depth of the notch, so a device that can automatically inspect it is desired. Automatic manufacturing equipment has high productivity, and it is difficult to perform automated inspections in a short period of time, especially notch inspections, which are difficult to perform accurately in a short period of time, and inspections are still performed manually. It had been done.

In view of the above-mentioned problems, the present invention aims to provide a device that can inspect the installation condition of a releasable fitting in a short time.Examples of the present invention will be described below with reference to the drawings. .

FIG. 1 is a diagram showing an inspection device according to the present invention together with a discharging device 1 of a slide fastener manufacturing device with a releasable fitting endpiece.

The discharge device 1 includes a feed roller 2 which is rotated at appropriate times and a press roller 6 which is provided to freely rotate.
The press roller is raised as necessary to move the slide fastener 4 (see FIG. 3) forward and discharge it from the fastener manufacturing apparatus. The fastener manufacturing apparatus has a transfer device 7 in the form of a gripper 5 (FIG. 2), and the gripper 5 moves along a guide rod 7 while gripping the tip of the tape 6 of the slide fastener 4.1. During this time, the insert pin 8, box pin 9, and box 11 are attached by various devices (not shown), and the gripper 5
By the time the tape reaches the position shown in FIG. 2, the tape has been cut to the desired length, and the slide fastener with a releasable fitting is completed.

The inspection device has an upper mold 16 and a lower mold 17 that are movable in the vertical direction. The upper mold 16 is fixed to a cylinder 19 of an air cylinder device 18, and the lower mold 17 is fixed to a piston rod 21, and the air cylinder device The expansion and contraction of 18 causes them to approach each other and move away from each other. The upper mold 16 is pressed downward by a compression spring 26 inserted between it and the frame 22 of the inspection device, and the lower mold 17 is pressed upward by a spring 24 inserted between it and the frame 22. has been added. The spring 24 is selected to be stronger than the spring 26, so that when the air cylinder device 18 contracts from the state shown in FIG.

A stopper (not shown) is provided for the upward movement of the lower mold 17, and the lower mold is positioned at a position where the box 11 enters a box storage recess 25 provided as a box mounting portion at the tip of the lower mold. (See Figure 6). A corresponding recess 26 is also formed in the upper mold 16 and is provided as a box placement part.
Accordingly, when the air cylinder device 18 is further deflated, the box 11 is completely accommodated in the recess 25, 26 and gripped by the upper and lower molds 16 and 17, as shown in FIG.

The lower mold 17 is provided with a plunger 27 pressed by a spring so as to protrude into the recess 25. It is then displaced downwardly, blocking the optical path of the photosensor 28 (emitter on one side, receiver on the other) as shown in FIG. 3, thereby providing a signal indicating the presence of the box 11. When the upper and lower molds 16, 17 are opened, the plunger 27 serves to eject the box 11 from the recess 25 under the action of the spring. The upper and lower molds 16 and 17 are each provided with a photosensor 29 (one emitter, the other a receiver), and their optical paths are blocked by the insert pin 8 and the box rod 9. When the amount of light passing between the two exceeds a predetermined value, a signal indicating an abnormality is generated.

Therefore, it is detected that the amount of light passing between the insert pin 8 and the box rod 9 is less than a predetermined value, and the point where these rods exist and the point where these rods are parallel and close to each other and there is no wide open part are detected. This can be confirmed. The upper mold 16 is provided with an inspection member that is movable relative to the upper mold 16. In the illustrated example, the inspection member is in the form of a swinging lever 31, with an insert pin 8, a box pin 9, and
and an inspection projection 62 positioned to fit into the notch 12, 16, 14 of the box 11. Swing lever 6
1 is biased by a spring 63 in a counterclockwise direction around a pin 64 as seen in the figure, but the upper and lower molds 16.1
7 swings clockwise due to the engagement of the bottom of the notch 12, 16, 14 with the test protrusion 62 when it closes. This swing amount is detected by the displacement detection device 65. In the illustrated example, this detection device is an indicator that incorporates a dial gauge type meter and can display the amount of displacement. If the detected amount of rocking of the rocking lever 31 is greater than or equal to a predetermined value, the notch 12.16
．． This indicates that at least one of the 14 is shallower than the desired depth or is not formed. Incidentally, the amount of swing of the swing lever 61 may be detected by moving the lever 61 and the bottle 34 together and measuring the amount of rotation of the pin 640. Although the inspection member is shown in the form of a swing lever, it may be provided so as to move relative to the upper mold 16 in the vertical direction.

The inspection device further includes a deflection device 67 for directing the inspected slide fastener 4 toward the discharge tray 36, and this device takes the form of an air cylinder and expands at a time to be described later to cause the slide fastener 4 to slide as shown in FIG. The tip of the fastener 4 is pushed toward the tray 66.

Next, the overall operation for inspection will be explained. gripper 5
grips the tip of the slide fastener 4 and moves the box 11 through the discharge device 1 until it reaches the position corresponding to the recess 25. When the gripper 5 reaches this position, a limit switch (not shown) sends a signal to the inspection device. As a result, the air cylinder device 18 contracts, the upper die 16 and the lower die 17 close to grip the box 11, and the press roller 6 rises to sandwich the slide fastener 4 with the feed roller 2.This state is The clipper 5 releases the slide fastener 4 according to the signal detected by the limit switch 68 and returns to the starting point along the guide rod 7, and from then on, the clipper 5 remains attached to the fastener stringer regardless of the operation of the inspection device until the next slide fastener is completed. Works to attach the releasable fitting.As can be seen from the above-mentioned configuration for inspection, when the upper mold 16 and the lower mold 17 are closed, the 6
Two types of tests are carried out: the presence of the insert pin 8, the box pin 9, and the box 11, the depth of the notches 12, 16, 14, and the spacing between the insert pin 8 and the box pin 9. When the inspection is completed, the air cylinder device 18 is extended and the upper and lower molds 16 and 17 are opened. This open state is sensed by the limit switch 69, and the resulting signal causes the direction changing device 37 to extend and move the tip of the slide fastener 4 to the tray 66. Nimuko pushes him away. Simultaneously with the operation of the deflection device 67, or at any time in its predecessor, the feed roller 2 begins to rotate, thereby feeding the slide fastener to the discharge tray 3B. A sorting device (not shown) is provided on the discharge tray, and receives a signal from the inspection device and discharges defective products from the system.

FIG. 6 shows another embodiment of the present invention, which has the same configuration as the example shown in FIG. 1 except for the points specifically explained below, and the same components are denoted by the same reference numerals. It is. In the example shown in FIG. 6, the plunger 61 is pressed upward by the spring 62, so when the upper mold 16 and the lower mold 17 are opened, the box 11 is ejected from the box storage recess 25, but the presence of the box is detected. It has no function. The lower mold 17 has a hole 63
A photosensor 64 is installed in the hole. The photosensor 64 has a light emitting part that irradiates a light beam almost perpendicularly to one surface of the box 110, and a light receiving part that receives reflected light from this one surface, and when the box is present, this reflected light is present. Its existence can now be confirmed.

As is clear from the above configuration, in the present invention, the depth of the insert pin, the box pin, and the caulking notch provided in the box can be confirmed by the inspection protrusion at the same time as the box is gripped by the upper mold and the lower mold. , accurate inspection is possible in a short time.
