New description: [New technical field] This creation is related to the technology of blow molding machines for blowing plastic bottles, especially one that continuously transports preforms one by one through a heating device by a conveying device. The configuration of the blow molding machine for improving the heating efficiency by changing the distance between the preforms by the variable distance device and then feeding the blow molding device. [Prior Art] Blow molding machines for producing plastic bottles such as P E T usually include an embryo device, a conveying device, a heating device, a blow molding device, and a product take-out device. Generally, the preform is transported from the embryo device to the transport device, and the preform is transported by the transport device to a predetermined temperature by a heating device, and then sent to a mold of the blow molding device for blow molding, and finally The blow molded finished product is sent out by the finished product take-up device. In order to increase production efficiency, several sets of molds are often arranged side by side in the blow molding unit to simultaneously blow several preforms into finished products. Therefore, the spacing between the preforms when the preforms are fed into the blow molding unit must correspond to the distance between the respective molds, so that the preforms are placed in the blow molding unit to be positioned at predetermined positions of the respective molds. An example of a blow molding apparatus disclosed in the blow molding apparatus and the molding method invention patent of the Japanese Patent Publication No. 365573 is an example. The overall structure of the blow molding device is composed of a preform supply portion, a preform heating portion, a blow molding portion, a product take-out portion, and a preform conveying portion, and the overall structural configuration is as follows: The blank conveying portion is large to have a rectangular shape, and the blow molding portion of the M336152 is disposed on a short side thereof, and the preform supply portion and the product take-out portion are disposed adjacent to one of the long sides adjacent to the short side, and the pre-preparation portion The preform heating portion is disposed between the preform supply portion and the blow molding portion. The spacing between the respective conveying members of the preform conveying portion is equivalent to the distance between the respective molds in the blow molding portion, so that the preforms supported by the respective conveying members are conveyed by the distance between the molds. Pass the preform heating section.
但是，前述專利中任兩相鄰的預塑胚之間有相當的的 ，離’這會使得加熱部之單位長度内所能加熱的預塑喊 量相對變少，進而讓預塑坯加熱部的加熱效率相對變差。 再者，該吹塑成形部係直接設置在預塑坯運送部之路 徑上，因此該吹塑成形部在對預塑胚進行吹塑成形工作時 二整個預塑&運送部是必需停止的。如此的結構配置會使 得該預塑坯加熱部的加熱效率再受到影響。 曰 前述的這些加熱效率不佳的問題，在能源日漸短缺的 今日，實在是一種絕對必需加以改進之缺失。 【新型内容】 本創作之主要目的，在於解決上述的問題而提供 =成型機之配置結構，其主要是藉由輸料置將瓶胚一 個接-個地連«送通過加熱裝置，再__裝置 ^瓦胚之間距後送人吹塑成财置，而可達到節能之ς 本創作之次 目的係在於’該變距裝置係以夾爪直接 M336152 夾持瓶胚，進行改變間距及運送工作，因此不需移動沈重 的瓶胚座，而能達到快速移動瓶胚之效果。 為達前述目的，本創作之吹塑成型機具有一機台，該 機台上設置一輸送裝置，且對應該輸送裝置之輸送路徑設 * 置一加熱裝置，而由一入胚裝置載送瓶胚至該輸送裝置， 而由輸送裝置載送瓶胚經過加熱裝置後，經變距裝置改變 瓶胚之間距，再由一取料裝置將瓶胚送至一吹塑成型裝置 之各模具内以吹塑為成品，再由取料裝置將成品取出。 • 其中，該輸送裝置具有多數比鄰設置之瓶胚座，以由 各瓶胚座分別載送瓶胚，並且將瓶胚一個接一個地連續輸 送通過該加熱裝置；而該輸送裝置與該吹塑成型裝置之間 係以一變距裝置連接，該變距裝置承接該輸送裝置送來之 瓶胚後會改變各瓶胚之間距至符合吹塑成型裝置之需要 後，再送入該吹塑成型裝置。 由於該輸送裝置是以比鄭設置之瓶胚座將瓶胚一個 接一個地連續輸送通過加熱裝置，因此該加熱裝置之單位 ⑩ 長度内所能加熱的瓶胚數量相對增加許多，而能有效地提 升加熱裝置的加熱效率，以達到節能之功效。 β 再者，該變距裝置係由伺服馬達連動螺桿，而該螺桿 - 具有一變距之導槽，該導槽鄰靠於該輸送裝置的一段其節 距相同於輸送裝置之瓶胚座間距，且該導槽鄰靠於該吹塑 成型裝置的一段，其節距相同於吹塑成型單元中之各模具 間距，而該變距裝置具有數夾爪，各夾爪係對應該螺桿之 導槽逐圈設置，以由各夾爪直接夾持輸送裝置送來之瓶 胚，再經由螺桿帶動各夾爪位移以改變瓶胚間距 7 M336152 輪此，該變距货罢Ab 間距及運送工作，因此二直接央持瓶胚，進行改變 快速移動瓶胚之效果而移動沈重的瓶胚座，而能達到 ，、附圖中，獲得深入了解。 【實施方式】 請參閱Ξ?:二作，佳實施例詳細說明如下。 配置結構示意圖。、誃^糸本創作之吹塑成型機的整體 1〇上設置-輪送裂置1、型機具有—機台.該機台 毁置一加熱裝置2、， ’且對應該輸送裝置1之輸送路徑 襄置1，再由輸送裝ϋ"：胚裝置3載送瓶胚至該輸送 由〜變距裝置4銜接瓶肢、严瓶胚經過加熱裝置2，而後 置5將瓶胚送入—吹^改變瓶胚間距後，由一取料裝 吹塑為成品，最後再6中之各模具61内以供 該輸送褒置1係之卜衣置5將成品运出。 ^具有兩平行的長邊 長邊:1"12之兩端的圓弧邊113114。 睛麥閱圖 2，JL /έ, 4r ^ ι >, 极巢置之配置示咅圖、。朴之輸送敦置、加熱裝置及入 U上繞奸—心12 裝置1於前述之輸送路徑 從動輪14所共同驅動，=12係由-主動輪- 极座15,以由各瓶胚座15=ΐ上比鄰設置有多數個 1 ο分別載送瓶胚，將瓶胚- M336152 一個地連續輸送通過該加熱裝置2。 μ力〃、、衣置2於该輸送路徑11的兩側分別設置多數 個加熱裔21，俾由各加熱器21對瓶胚進行加熱至吹朔 型所需之溫度。However, in the aforementioned patents, there is a considerable amount between two adjacent pre-plasticized preforms, which will cause the amount of pre-plasticity that can be heated per unit length of the heating portion to be relatively small, thereby allowing the preform to be heated. The heating efficiency is relatively poor. Furthermore, the blow molding portion is directly disposed on the path of the preform conveying portion, so that the entire preforming & conveying portion must be stopped when the blow molding portion performs the blow molding operation on the preformed preform. . Such a structural configuration causes the heating efficiency of the preform heating portion to be further affected.前述 The aforementioned problems of poor heating efficiency, in the current shortage of energy, are really a lack of improvement. [New content] The main purpose of this creation is to solve the above problems and provide the configuration structure of the molding machine. The main purpose is to connect the preforms one by one through the feeding device to the heating device, and then __ The device will be blown into the fortune between the embryos, and the energy can be saved. The second purpose of this creation is to use the jaws to directly clamp the preforms with the gripper M336152 to change the spacing and transport work. Therefore, it is possible to achieve the effect of moving the preform quickly without moving the heavy preform holder. In order to achieve the above object, the blow molding machine of the present invention has a machine table on which a conveying device is disposed, and a heating device is disposed corresponding to the conveying path of the conveying device, and the bottle is carried by an embryo device. The embryo is sent to the conveying device, and after the conveying device carries the preform through the heating device, the spacing between the preforms is changed by the variable distance device, and then the preform is sent to each mold of a blow molding device by a reclaiming device. The blow molding is finished, and the finished product is taken out by the reclaiming device. Wherein the conveying device has a plurality of adjacent preform holders for respectively carrying the preforms from the respective preform holders, and continuously conveying the preforms one by one through the heating device; and the conveying device and the blowing device The forming devices are connected by a variable distance device, and the variable distance device receives the preforms sent by the conveying device, and then changes the distance between the preforms to meet the needs of the blow molding device, and then feeds the blow molding device. . Since the conveying device continuously conveys the preforms one by one through the heating device than the preform holder, the number of preforms that can be heated in the unit length of the heating device is relatively increased, and can be effectively Improve the heating efficiency of the heating device to achieve energy saving. Further, the variable distance device is linked by a servo motor, and the screw has a variable pitch guide groove, and the guide groove abuts against a section of the conveying device, the pitch of which is the same as the spacing of the preform holder of the conveying device. And the guide groove abuts against a section of the blow molding device, the pitch of which is the same as the distance between the molds in the blow molding unit, and the variable distance device has a plurality of jaws, and each of the jaws corresponds to the guide of the screw The groove is arranged in a circle, so that the preforms sent by the conveying device are directly clamped by the respective jaws, and then the displacement of each jaw is changed by the screw to change the spacing of the preforms. 7 M336152 This is the pitch and the transportation work. Therefore, the second directly holding the preform, changing the effect of rapidly moving the preform and moving the heavy preform holder, can be achieved, and the drawing is obtained in-depth.
