Description

M275952 3. Creation Instructions (1)-[Technical Field to which the New Type belongs] This case is an injection positioning device for the upper stop, the lower stop, and the insertion end (bird claw) of an open zipper, especially for pulling back the chain before the injection To pinpoint

Devices, especially those who enter, must also be provided with a detection device to detect the molds that are positioned for injection. I [Prior art] The basic components of the zipper according to the opening are cloth tape, sprocket, chin block, plug (bird claw), slider, reinforcing patch, top stop and other parts. The relative positions between 苴 have a certain size range. If the size bit is correct, the function of the opening zipper is affected, and there is even no 1 effect. Therefore, when the opening zipper is injection-molded with a lower stop, a pin, and an upper stop, it must be positioned accurately to exert its correct effect. • Activities: Some of the production methods in use are used by some operators. Some are visualized by the operator, and assisted by the positioner, which will be pulled up. After the installation, the machine will shoot the lower block and pin of the zipper 1 993 # 11 θ 1 8 s ^ Zuorenyuan Service Company (Kaisheng Co., Ltd.) stated on November 18th that "Xi Xi" held Coffee t, the heart of the molding positioning mechanism, made of plastic Λ, bird claws, and lower-end shot frost-type producers, such as the case of Shengsheng Co., Ltd.

Because the description of the creation of nylon zippers (2) is limited to plastic zippers, not suitable for nylon zippers. The teeth of the zippers are soft, and the positioning of gear hooks is not easy. In view of this, the applicant has long been engaged in the research, development, and production of zipper machine fish for many years, and has made intensive research to overcome the above-mentioned shortcomings. M explores again and again, and founds = the "opening zipper injection positioning device" in this case. To further reveal the specific technical content of this case, please first refer to the drawings, where 'Figure 1 is the general view of the case, Figure 2 is a perspective view of the branching and cutting mechanism of the case, and Figure 3 is an enlarged view of the injection mechanism of the case, and Figure 4 is This is a perspective view of the entrainment mechanism. The primary purpose of this case is to provide a fully automatic positioning device that is not limited to the use of nylon zippers but can be used for open zippers such as metal and plastic. Maybe I can call it a "universal type". Another object of the present case is to provide a positioning device with a simple structure, which does not require gears for hook and pinion positioning, and eliminates the need for a full-automatic positioner. Yet another object of this case is to provide a device that can pull on the lower rib, put on the slider, and then shoot the lower rib, insert pin, and top stop. By this, the top stop can be designed to completely block the zipper, It can not be pulled out, and the child is injured due to the accidental swallowing safety stop device. 2. Another purpose of this case is to provide a positioning device with accurate positioning and more uniform and stable product quality. In order to achieve the above-mentioned purpose, basically, the positioning device of the present case includes a stripping mechanism 1, a bracket 2, a slider induction detection mechanism 3, an injection mold 4, a clamping mechanism 5, a positioning cover mechanism 6, A rewind positioning mechanism 7,

Page 6 M275952 4. The combination of creative instructions (3) and a positioning detection mechanism 8. [Embodiment] Among them, the tape-separating mechanism 1 is divided into a left and right sides by a ring 11 and a spacer 1 2 ′ inside it for subsequent operations. The bracket 2 is used for supporting and passing the zipper. Therefore, the bracket 2 has two frame slots 2 1 ′ for receiving and traveling the chain belt, respectively. The bracket 2 is co-located with the aforementioned belt separating mechanism 1. The slider detection induction mechanism 3 is located near the injection mold 4 for the purpose of retaining the zipper head in the mold and crushing the mold when the mold is closed. This slider detection induction mechanism can be, for example, but not limited to a proximity switch, or Sensors, such as photoelectric switches, can be used to close the mold after leaving the zipper head away from the mold. Generally speaking, this pull head detection sensor element must be installed before and after the mold. The injection mold 4 (the upper mold is not shown) has two top stops, a lower stop and a bird :: Λtip) cavity. The injection mold 4 in this case is reversed, and when the chain moves from left to right, First through the upper end of the mold, and then U stop = tip, the reason for this reverse installation is that the unilateral chain in the opposite direction: penetrates on the single side in the opposite direction, and the zipper is in the • Timeliness, that is, it is easy to slide in the forward direction, but the reverse 2 female skirt can ensure the possibility of the zipper head being positioned in a specific reverse head to reduce failures. It is necessary to reduce the pressure to the zipper clamping mechanism 5 which is shown for clamping the tape. Basically, a motor ^ two moving Λ chain is used for the chain 'as shown in the figure to connect a slippery chain. ⑽, and the description of the creation of the slider M275952 (4) 'When the zipper is pulled', the completed opening member has been shot, and it is moved by one, and the motor 51 rotates a fixed number of turns, which will make the gear chain 52 Β 2 疋 length, And this length is the length of the zipper size (fixed size) ^: If the size and length are different, you can change the number of rotations of the motor 51: Suppose that after the fixed length is pulled out, the slider 53 is released and pulled to the positioning position 'And the slider 53 uses the injection time ^ chain to pull the next distance. Yikou to the original position ’One? t The tool is sensed, so ‘it has to have a pinch-in positioning sensor switch 55 ^ pinch-out positioning sensor switch 5 6’, that is, when the sensor switch acts, this pinching out and pinching action stops. In fact, 'Since the nylon zipper is only a single mask sprocket, therefore, = the zipper, the teeth face downward' and 'the motor 51 in this case is driven by i, and the wheel 52 is not limited to the side, that is, it must also be in other positions . The positioning cover mechanism 6 is located behind the injection mold 4, which is a plate-* and * T for lifting. The purpose is to position the sprocket in the injection slot when it is pressed down, and When you want to pull the chain after shooting, the cover plate mechanism 6 will rise so that the chain and the bones will pass after shooting. In addition, there is a positioning cover sensor 61 (because the projection angle is not set). Can =), when the zipper is not pulled to the correct position, the positioning cover mechanism 6 is not pressed down, the induction switch 61 is activated, so that the mold cannot be ejected. The adjustment is set on the side of the bracket 2 above, the purpose of which is the cylinder 72 :, the two books are composed of-the pressure belt cylinder 71 and the two back cylinders 72, and the pressure belt cylinder 71 can press down the chain, Back cylinder

Page 8 M275952 IV. Creative Instructions (5) 72 can press the single-sided chain separately and make it slightly back position. Open; mold; Reverse loading, so when the chain is dragged i ^ over the position, some will be pulled back, and at this time the zipper is pressed in the tooth groove of the mold by the positioning cover mechanism 6 ' Therefore, when retracting and retracting, the first teeth of the left and right bars can obtain the correct relative positions with the lower gear and the insert, respectively: The positioning completion detection mechanism 8 is set in the lower gear of the mold and the sprocket of the insert. When the first tooth is placed under $, a detection switch is added. When the first tooth reaches the positioning, the detection mechanism will send a letter = the detection of the-tooth reaches the positioning, at this time the mold will only be inserted into the mold: injection . Broken = see! In the actual implementation of this case, the-strip is not continuously determined: "ί" The positioning cover mechanism 6 is pressed down to release the zipper teeth 5 ~, and the structure 6 is injected into the zipper tooth groove of the mold 6, then The clamping mechanism 5 releases the held-down zipper 'belt-cylinder 71 and presses the belt located on the bracket 2 at the same time ::: the chain belt, and the rear pass cylinder 72 presses down the left and right chains, respectively, and the two side belts retract To positioning 'and then according to the programmed control L ^ Α: production, output, ejection, and then pull to the next zipper is determined as a% automation operation. With the setting: by the implementation of this case, it can be automated Outside of work, for the purpose. To make the injection position accurate, and then to the case disclosed in this case, is the kind of the preferred embodiment, which is a local change.
