Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a machine for assembling shoes along a shoe production line. In particular, the machine allows the use of water-based glue to fit the upper side of the shoe to the insole. [Prior Art] For automatic and semi-automatic assembly of shoes, it is known to use so-called "side-lasting machines" which use thermoplastic glue to perform shoe side assembly. These machines have an operating area that houses shoes that have been partially assembled into a special style. Typically, the upper portion has been glued to the toe of the insole and the machine must be glued to the upper side (middle machine) or the upper remaining part (middle and back-lasting machine). In this technique, in order to perform machine gluing of the toe, it has recently been proposed to use a water-based glue in order to achieve a satisfactory satisfaction of the upper to the toe of the insole by means of special machines that are compatible with the requirements of the aqueous adhesives of the thermoplastic adhesives. glued. In order to glue the sides, it has been proposed to spray a water-based glue in place of the coated thermoplastic adhesive. However, in such machines, it has been found that aqueous gelling often takes too long. Moreover, even when achieved within an acceptable setting time, the strength of the aqueous gel in the side regions (which are typically the most stressed during use of the shoe) has proven to be completely unsatisfactory. However, due to various advantages such as less environmental pollution, lower machine power consumption, and lower gel synthesis, the use of such side-side automatic gluing of aqueous glue is still expected. Moreover, one of the advantages of using an aqueous glue is that it is softer than a shoe glued with a thermoplastic adhesive. As will be described later, in fact, the film of the thermoplastic adhesive makes the shoe -4-201130441 more rigid. Therefore, it is very advantageous to apply water-based glue at the portion above the upper side of the shoe. Among various shoes, for example, sports shoes are one of the most beneficial shoes that can benefit from the use of water-based glue. Strictly speaking, however, sneakers are the most stress-dependent shoes along the side of the shoe, and they are necessary for strong adhesion even under such stresses. SUMMARY OF THE INVENTION A primary object of the present invention is to provide an assembly machine that allows the upper side to be automatically glued to the insole using an aqueous glue to provide a fast and strong enough and reliable adhesion. In view of this object, it has been contemplated in accordance with the present invention to provide a machine for assembling a shoe side to an insole using an aqueous glue, comprising an operating area having a support pad for receiving a shoe to be assembled, above the operating area Providing a water-based glue dispenser for applying water-based glue on the operation area where the shoe side and the insole are glued together, and two presses including fingers are provided along both sides of the operation area Units, the fingers may be self-retracting in the inactive position, sliding toward the sole and over the sole to press the insole along the side of the shoe to press the side surface of the upper to be glued, characterized in that The fingers are heated to conduct heat during the gluing to the upper portion where the fingers are pressed. [Embodiment] Referring to the drawings, Fig. 1 shows a machine (indicated generally at 10) for assembling a shoe according to the present invention.

The operating area sequentially includes a shoe form to be joined. The inner support pad 12 is so as to be stably positioned during the vehicle manufacturing process. A support pad 13 may be further provided for supporting the toe area of the shoe. The lateral clamping and pressing unit are located opposite the two sides of the operation area. 1 4 and 15, above which are disposed corresponding clamps 16, 17 for clamping and pulling the upper part. There are two dispensers 18 and 19 above the operation area for the glue to be glued. The side edges are coated with a water-based glue. The dispensers are driven by a motor to move along a predetermined path relative to the sole in the operating zone to apply glue in the predetermined upper and bottom regions to be glued together. It can be defined using a variety of systems that are well known to the region and will therefore not be described in detail herein. For example, known self-learning systems can be used. The dispensers can be moved by the electronic control unit 20 Memory and control and various kinds of machines The drive path, which is known per se and is equipped with appropriate means for the operator to display and import data and commands.

As will become apparent below, the two series of fingers of the two units are positioned relative to one another And can be operated from the inoperative position shown in Fig. 2, slightly moving over the sole toward each other, and thus pressing the insole 24 against the corresponding side edge 23 of the upper. The movement is actuated by the corresponding The means 25 and 26 can also advantageously set the two series of fingers 2 1 below, so that the pressure is different
S 按墊27及28設有致動系統，使得能壓按他們抵著鞋側區。 201130441 如第2圖中所例示之示意圖，基本上，如嫻熟該技術者所 能輕易想像者，在操作期間，操作者將鞋子裝設在支撐墊12 上，使趾部停放在支撐墊13上且開始膠合作業。側夾鉗16及 17夾鉗兩上側部位且將其向上拉取。之後，壓按墊27及28 朝彼此移動以便壓按鞋側且將鞋幫保持位於此等區中。 配發器18、19沿預定路徑移動且將水性膠塗佈在待膠合 之指定區中，其包括該等鞋幫之側邊部位。 之後’兩系列之指狀物2 1朝彼此滑動，以便使夾鉗所釋 放之上緣鬆開且壓按他們抵著鞋內底。第3圖以示意表示形成 左邊單元之指狀物系列。 有利的是，該等指狀物係具有彈性地以垂直向裝設在機身 29上，該機身係爲每一系列而設且爲使指狀物系列位移而由個 別致動器予以移動。依此方式，取決於沿其延伸之鞋側之高度 或傾斜度的小變異量，該等指狀物能配合其垂直傾斜度及/或 位置。 依據本發明之創新原理，將該等指狀物2 1 (有利地由金屬 製成）加熱’以便在膠合期間將熱傳導至該等指狀物所壓抵之 鞋幫部。以此方式結合壓按及加熱達成膠合以水性膠之鞋幫之 部側區域。已經發現介於60°C與90°C之間之加熱溫度，且尤 其是約80°C之溫度，係有利的。熱壓該等指狀物所需時間在6 與1 〇秒之間，且尤其是約8秒，係有利的。 訝異的是’發現到可達成鞋幫側邊至鞋內底之快速、可靠 且耐久之水性膠合。S Pads 27 and 28 are provided with an actuation system that allows them to be pressed against the side regions of the shoe. 201130441 As schematically illustrated in Fig. 2, basically, as can be easily imagined by those skilled in the art, during operation, the operator mounts the shoe on the support pad 12 to park the toe on the support pad 13. And began the rubber industry. The side clamps 16 and 17 clamp both upper portions and pull them up. Thereafter, the pressing pads 27 and 28 are moved toward each other to press the shoe side and hold the upper in this zone. The dispensers 18, 19 are moved along a predetermined path and the aqueous glue is applied to a designated area to be glued, which includes the side portions of the uppers. The two series of fingers 2 1 then slide towards each other so that the upper edges of the jaws are released and pressed against the insole. Figure 3 is a schematic representation of a series of fingers forming the left unit. Advantageously, the fingers are resiliently mounted on the fuselage 29 in a vertical orientation, the fuselage being provided for each series and being moved by individual actuators for displacement of the series of fingers . In this manner, the fingers can conform to their vertical inclination and/or position depending on the amount of variation in the height or inclination of the shoe side extending therethrough. In accordance with the innovative principles of the present invention, the fingers 2 1 (favorably made of metal) are heated to conduct heat during bonding to the upper portion to which the fingers are pressed. In this way, press-fitting and heating are combined to achieve a side region of the upper portion of the upper surface of the water-based glue. It has been found that a heating temperature between 60 ° C and 90 ° C, and especially a temperature of about 80 ° C, is advantageous. The time required to hot press the fingers is between 6 and 1 sec, and especially about 8 seconds, which is advantageous. Surprisingly, it was found to be a fast, reliable and durable water-based glue that can reach the side of the upper to the insole.
S 在第3圖所示之實施例中，相鄰之指狀物係結合成對 201130441 且每一對之兩個指狀物共用電熱元件30。如亦可清楚見諸於第 4圖（沿第3圖中之方向IV-IV所見）及第5圖（沿第4圖中之直 線V_V的橫切面）中者，每一指狀物由支撐元件3 1所支撐，該 支撐元件3 1終止在圓柱柄32後，供裝設在機身29之相稱座 中。此允許該等指狀物之快速替換以及稍微之軸旋轉，以便配 合待壓按表面之傾斜度。在此情況中，每一指狀物會有一加熱 器，故兩相鄰之指狀物彼此完全無關。這可見諸於第6及7圖 中，其例如顯示設有安裝在中央座或孔中之電熱器130的單一 指狀物121。該指狀物將裝設在一單一支撐元件31上。 另一方式，亦可能提供用於連接每一對指狀物之間的中心 接合，其加熱器係配置在該接合內部以便對該對指狀物加熱。 已發現到若該等指狀物之每一者之表面以滑動與鞋底接 觸、形成兩區、依序配置在滑動方向，其摩擦係數彼此相異的 話則有利。尤其是，較接近該指狀物前端之表面的第一分部有 利地具有較第二分部爲大之滑動摩擦力，以便對已膠合之上部 施加進一步之拉取動作。爲達成此，每一指狀物之滑動表面的 前端分部可與適當襯料製成之條帶33排列，如爲皮或適當塑 料製成之條帶。爲了使傳導至已膠合之壓按鞋幫的熱量達到最 大，指狀物表面之第二部位反而有利地以金屬製成。不用兩種 相異材料，其亦可能想像，例如，相異之指狀物表面處理，以 便其具有較平滑且易滑之一區域，以及較不平滑之一區域。該 表面亦可爲鋸齒狀。 第8及9圖表示該等指狀物之結構變體，其中該指狀物（通S In the embodiment shown in Fig. 3, adjacent fingers are joined in pairs 201130441 and the two fingers of each pair share the electric heating element 30. If it can be clearly seen in Figure 4 (as seen in the direction IV-IV in Figure 3) and in Figure 5 (the cross-section along the line V_V in Figure 4), each finger is supported by Supported by element 31, the support element 31 terminates behind a cylindrical shank 32 for attachment in a commissure seat of the fuselage 29. This allows for a quick replacement of the fingers and a slight axis rotation to match the inclination of the surface to be pressed. In this case, each finger has a heater so that the two adjacent fingers are completely independent of each other. This can be seen in Figures 6 and 7, which show, for example, a single finger 121 provided with an electric heater 130 mounted in a central seat or aperture. The fingers will be mounted on a single support element 31. Alternatively, it is also possible to provide a central engagement between each pair of fingers with a heater disposed within the joint to heat the pair of fingers. It has been found to be advantageous if the surface of each of the fingers is slidably in contact with the sole, forming two zones, sequentially disposed in the sliding direction, and having different coefficients of friction. In particular, the first portion that is closer to the surface of the front end of the finger advantageously has a greater sliding friction than the second portion to apply a further pulling action to the glued upper portion. To achieve this, the front end portion of the sliding surface of each finger can be aligned with a strip 33 of suitable lining, such as a strip of skin or suitable plastic. In order to maximize the amount of heat transferred to the glued upper, the second portion of the surface of the finger is advantageously made of metal. Instead of two dissimilar materials, it is also possible to imagine, for example, a different finger surface treatment so that it has a smoother and more slippery area, and a less smooth one. The surface can also be serrated. Figures 8 and 9 show structural variants of the fingers, wherein the fingers

The foil 235 is spaced from its front end toward the bottom of the fuselage 23 4 so as to be slightly curved during at least the first stage of sliding on the sole. The front end of the foil can be bent upward to form a receiving surface that slides smoothly over the shoe. The foil may be made of metal to maximize heat transfer and also have a surface treatment as described above. In all variations of the finger embodiments, the support members 31 can be used and the fingers are free to pivot about their longitudinal axes. It is clear at this point how the intended purpose has been achieved. With the heated finger machine according to the present invention, it has been found that the water-based glue can also be used to quickly, stably and permanently extend the upper side to the sole and have a bonding strength, for example, satisfactory for sports shoes.
