0，並且又複數個該一 • 對兩個物品儲存格被並列地配置。在每個分隔構件1 1之下 、 端，設置有開口 11a及lib可局部地暴露輸送單元20。 , 在寬度方向之每個物品儲存格1 〇內側之一端上，設置 有一個可朝寬度方向上移動之物品分隔件1 3，其可依照被容 納的物品A之外徑而被移動。 每個物品儲存格1 0之前開口設置有一個掉落防止板1 4 蓋住在寬度方向上之開口的一端。掉落防止板14包含有一 個延伸於垂直方向上的板狀構件，及將板1 4之一端朝寬度 ® 方向折疊成U形而在整個垂直方向上形成之一個折疊部分 14a。掉落防止板14在寬度方向上之一端的上及下端’係可 轉動地被輸送裝置本體1所支撐，以打開及關閉物品儲存格 10之前開口的寬度方向上之一端。又，做爲可在垂直方向上 移動的物品接觸構件之接觸板1 5，係可脫離地配合到掉落防 止板1 4之折疊部分1 4 a。 由實質上矩形板形狀構件形成的接觸板1 5，具有一個接 觸部分15a，其可接觸儲存於物品儲存格1〇之中被置放於最 200535740 高的一個物品A，及一個啣接部分15b，其與掉落防止板14 之折疊部分14a啣接而可在垂直方向上移動。啣接部分i5b 係由將從接觸部分1 5 a之一端延伸之構件彎曲成L型所形 成。第1配合孔1 5c及第2配合孔1 5d各被形成於啣接部分 1 5b之頂側及底側，並且接觸板1 5可分離地將第1配合螺絲 1 5 e及第2配合螺絲1 5 f分別螺鎖到第1配合孔1 5 c及第2 配合孔15d中，被配合到掉落防止板14。因而，如第4圖所 示，因爲第1配合螺絲1 5e被定位於朝向掉落防止板14之 • 折疊部分14a之一端，且第2配合螺絲15f被定位於掉落防 、 止板14之折疊部分14a之後面，故使接觸板15可朝向垂直 ^ 方向移動而不脫離掉落防止板1 4。又，可將接觸板1 5保持 於物品儲存格1 〇之上部分的保持構件1 6，經由第1配合螺 絲15e而被配合到接觸板15。保持構件16包含有板狀構件， 其中之一個被聯結到接觸板1 5。將保持構件1 6之另一端彎 曲成鉤形時，可形成一個鉤部1 6 a。 輸送單元20包括：一個被插入第1分隔構件11中之單 ^ 元本體2 1、做爲可打開每個物品儲存格1 0之底部的一對門 構件之門板22、做爲一對物品保持構件之用而可伸入每個物 品儲存格10內之物品保持板23、用於支撐物品可朝垂直方 法移動之保持板23的一對滑板24、一個用於限制門板22 向下轉動到實質水平位置之轉動限制板25、一個用於驅動門 板22及物品保持板23之馬達26、及一個用於將每個物品保 持板23伸入物品儲存格10內之凸輪構件27。 單元本體21係由蓋住輸送單元20之前、上及後面的框 200535740 架狀構件所形成，並且其在寬度方向上的兩邊被打開。用於 聯結單元本體2 1之前及後端側之補強構件2 1 a及2 1 b，實質 上各在垂直方向上被配合到單元本體21之中心部分及下端。 門板22位於各物品儲存格1 〇之下端，並且每一個之一 端經由一個心軸22a而可轉動地被支撐。一個彈簧22b配合 到門板22之每個心軸22a，並且彈簧22b之一端與門板22 之上面側啣接，而另一端被固定到單元本體2 1。因而，彈簧 22b迫使門板22向下。 ® 物品保持板23被配置於門板22上方，並且每個物品保 ' 持板2 3之頂端經由一個心軸2 3 a而可轉動地配合到滑板24 , 之下端側。心軸23a所穿過的一對軸承部23b，被裝設在物 品保持板23之上端側上，並且軸承部23b在其等之間的寬 度方向上配置有間隔。與凸輪構件27接觸的一個接觸部23c 被裝設於軸承部23b之間，並且接觸部23c係被形成向下朝 向凸輪構件27傾斜。 滑板24位於單元本體2 1 1而可朝垂直方向移動，並且 ^ 將滑板24朝向垂直方向移動之操作銷24a，被朝向板24之 頂端配合。每個操作銷24a之一端被插入配合到單元本體2 1 之前面的一個操作板24b之狹縫24c中而可朝垂直方向移 動，並且可與操作銷24a啣接之複數個溝24d，係在垂直方 向上成間隔地形成在狹縫24c中。因而，藉由任何一個之溝 24d與操作銷24a啣接之時，物品保持板23在垂直方向的位 置可被改變。 被形成實質半圓形之轉動限制板25，在門板22下方朝 200535740 水平方向轉動。因此，當轉動限制板25橫跨兩門板22時， 兩門板22被限制於向下轉動，且藉由轉動限制板25而被保 持於關閉狀態，如第7圖所示。當轉動限制板25轉動而朝 向其中一個門板22之時，另一個門板22可從轉動之限制中 釋放，並且向下轉動以打開該物品儲存格10之底部。 配置於單元本體21之上部的馬達26，被構成可向前及 向後轉動。一個延伸到單元本體2 1之下端的驅動軸26a，經 由一個齒輪單元26b而連接到馬達26。驅動軸26a可轉動地 ® 被補強構件2 1 a及2 1 b所支撐，並且轉動限制板25係配合 、 到其下端。因而，馬達26被連接到自動販賣機之控制單元（未 , 顯示），並且其轉數被控制單元所控制。 包含有其橫剖面爲橢圓形之高的構件之凸輪構件27，被 配合到驅動軸26a且與其成一體地轉動。在此情況時，凸輪 構件27被形成朝向驅動軸26a之橫剖面在縱方向的一端而 倚靠，並且其在圓周方向上之局部（朝向橫剖面在縱方向的 另一端）構成第1接觸部27a，其可與物品保持板23之接觸 • 部23c接觸。可與朝向物品保持板23之下端（尖端側）的下面 接觸之第2接觸部27b被形成可在徑向上朝向凸輪構件27 之下端突出。第2接觸部27b係與第1接觸部27a朝向相同 方向突出。 被構成如上述的輸送單元20,從下方被插入具有配置於 單元本體2 1之後側的分隔件2 1 c的分隔構件1 1內，並且由 螺絲等而被固定到分隔構件1 1。然後，單元本體2 1在寬度 方向之兩側，被第1分隔構件1 1之側邊蓋住，並且輸送單 -10- 200535740 元20之門板22及物品保持板23經由分隔構件1 1之開口 1 la 而被暴露到外側。物品A在此狀態下被堆疊於門板22而被 儲存，並且接觸板15被配合到掉落防止板14上，而使接觸 部1 5 a之下面與在最高位置之每個物品A的上面接觸。 其次，當一個物品A在物品輸送裝置中欲從一個物品儲 存格1 〇輸出時，如第1 〇圖所示，轉動限制板25被輸送單 元20之馬達26的旋轉所轉動。然後，凸輪構件27與轉動 限制板25 —起轉動，並且凸輪構件27之第1接觸部27a與 Φ 物品保持板23之接觸部23c ·接觸，而使物品保持板23朝向 、 物品儲存格1〇轉動。同時，凸輪構件27之第2接觸部27b . 移動到物品保持板23之下端之下方。此可造成物品保持板 23伸入物品儲存格10內，並且第2物品A被物品保持板23 從底部之啣接，造成其餘物品A被保持於物品儲存格1 0內。 在此過程中，被物品保持板2 3所保持的物品A，不僅被與 物品保持板23之頂端接觸的凸輪構件27之第1接觸部27a 所支撐，而且被與物品保持板23之下端（尖端側）接觸的第2 ® 接觸部27b所支撐。在此之後，當轉動限制板25之轉動進 行之時，門板22從被轉動限制板25限制其轉動的限制中釋 放，並且彈簧22c使門板22向下轉動，如第1 1圖所示。物 品儲存格1 〇之底部因而被打開，而將置放於最低的物品A 掉落而輸送。在物品A被輸送之後，輸送單元20之馬達26 朝向與輸送時之方向相反之方向的轉動，使轉動限制板2 5 關閉物品儲存格1 〇之底部，如第1 2圖所示。同時，凸輪構 件27從其與物品保持板23之接觸中釋放，並且被物品保持 200535740 板23保持的物品A及堆疊在其上的其它物品A掉落到門板 22上，如第13圖所示。然後，當接觸板15向下移動而與物 品A之上面接觸之時，被置放於最高的物品A之排列並未 受到物品A掉落之衝擊所擾亂。 當物品A待儲存到上述物品輸送裝置之一個物品儲存 格1 〇中之時，如第14圖所示，掉落防止板14被轉動，以 打開物品儲存格1 〇，接觸板1 5藉由與接觸板1 5聯結的保持 構件16之鉤部16a和掉落防止板14之頂端啣接，而被保持 Φ 於掉落防止板1 4之頂端，並且物品A可在該狀態下被儲存。 " 依此方式，因爲在此模式下構成本發明實施例的物品輸 ， 送裝置具備有接觸板15，其可與儲存於物品儲存格10中之 一個置放於最高的物品A接觸，使輸送操作可以可靠地完 成，而在最低置放的物品A被輸送之時，不會使其餘的物品 A之排列被掉落到門板22上之衝擊所擾亂或阻塞。 又，因爲接觸板15包括有可與物品A之上面接觸之接 觸部15a，及與掉落防止板14啣接之啣接部15b，接觸板15 ^ 可在與掉落防止板1 4啣接的狀態下朝向垂直方向移動，以 防止接觸板1 5由於物品輸送裝置之輸送操作而脫離物品A 之上面。 並且，因爲啣接接觸板1 5之保持構件1 6係位於掉落防 止板1 4之頂端，物品A可以在不必移除接觸板1 5之下，而 被儲存於物品儲存格1 〇中，因而形成物品A之有效的儲存。 又，接觸板1 5之可脫離結構，可使其在必要時被移除。 例如，若輕薄的物品被儲存之時，可將接觸板1 5配合，並 -12- 200535740 且當物品很厚之時，其儲存情況並不受掉落衝擊所影響，因 而可免去接觸板1 5。 附帶地，雖然上述實施例具有一個構造，其中接觸板1 5 係由其本身自重而與置放於最高的物品A接觸，但是，亦可 使一個物品接觸構件藉由一個如螺旋彈簧之壓迫構件而與 物品之上面接觸。 並且，雖然上述實施例中之接觸板1 5與的掉落防止板 14啣接而可朝向垂直方向移動，但是亦可使用一個延伸於垂 • 直方向且與接觸板15之啣接部15b啣接的啣接耦合件裝設 、 於分隔構件1 1或側板1 2上之時，可使物品接觸構件可移動 . 地與其啣接。 又，雖然上述實施例被構成爲，接觸板1 5係藉由將聯 結到接觸板15的保持構件16與掉落防止板14之上端啣接 而被保持於物品儲存格1 0之上部分中，但是接觸板1 5亦可 藉由將一個磁鐵裝設於物品儲存格1 0之上端而吸引接觸板 15之時，亦可被保持於物品儲存格10之上部分中。 ® 至此，在本說明書中說明的較佳實施例係僅供說明之 用’而非有限制上之涵意。本發明之範圍被陳述於附加的身 爲專利範圍中，其函蓋本發明之所有可能的修改。 【圖式簡單說明】 第1圖係顯示本發明一個較佳實施例之物品輸送裝置之 立體圖； 第2圖係顯示物品輸送裝置之主要部分的剖開立體圖； 第3圖係顯示一個物品接觸構件之剖開立體圖； -13-

Then, the unit body 21 is covered by the sides of the first partition member 11 on both sides in the width direction, and the door panel 22 and the article holding plate 23 of the transport order -10- 200535740 yuan 20 pass through the opening of the partition member 11 1 la while being exposed to the outside. The article A is stacked and stored on the door panel 22 in this state, and the contact plate 15 is fitted to the fall prevention plate 14 so that the lower portion of the contact portion 15 a contacts the upper surface of each article A at the highest position. . Next, when an article A is to be output from an article storage compartment 10 in the article conveying device, as shown in FIG. 10, the rotation restricting plate 25 is rotated by the rotation of the motor 26 of the conveying unit 20. Then, the cam member 27 rotates together with the rotation restricting plate 25, and the first contact portion 27a of the cam member 27 contacts the contact portion 23c of the Φ article holding plate 23, so that the article holding plate 23 faces the article storage compartment 10. Turn. At the same time, the second contact portion 27 b. Of the cam member 27 moves below the lower end of the article holding plate 23. This may cause the article holding plate 23 to protrude into the article storage compartment 10, and the second article A is connected by the article holding plate 23 from the bottom, causing the remaining articles A to be held in the article storage compartment 10. In this process, the article A held by the article holding plate 23 is not only supported by the first contact portion 27a of the cam member 27 in contact with the top end of the article holding plate 23, but also by the lower end of the article holding plate 23 ( The tip side) is supported by the second contact portion 27b. After that, when the rotation of the rotation restriction plate 25 is performed, the door plate 22 is released from the restriction by which the rotation restriction plate 25 restricts its rotation, and the spring 22c rotates the door plate 22 downward as shown in FIG. The bottom of the item storage compartment 10 is thus opened, and the item A placed at the lowest position is dropped and transported. After the article A is conveyed, the motor 26 of the conveying unit 20 is rotated in the direction opposite to the direction at the time of conveyance, so that the rotation restriction plate 25 closes the bottom of the article storage compartment 10, as shown in FIG. 12. At the same time, the cam member 27 is released from its contact with the article holding plate 23, and the article A held by the article holding 200535740 plate 23 and other articles A stacked thereon fall on the door plate 22, as shown in FIG. 13 . Then, when the contact plate 15 moves downward to contact the upper surface of the article A, the arrangement of the article A placed at the highest position is not disturbed by the impact of the dropping of the article A. When the article A is to be stored in one of the article storage compartments 10 of the above-mentioned article conveying device, as shown in FIG. 14, the fall prevention plate 14 is rotated to open the article storage compartment 10, and the contact plate 15 is opened by The hook portion 16a of the holding member 16 connected to the contact plate 15 and the top of the fall prevention plate 14 are engaged with each other, and are held at the top of the fall prevention plate 14 and the article A can be stored in this state. " In this way, because in this mode, the article conveyance constituting the embodiment of the present invention, the delivery device is provided with a contact plate 15 which can be in contact with one of the article A stored in the article storage compartment 10 at the highest position, so that The conveying operation can be reliably performed, and when the lowest placed article A is conveyed, the arrangement of the remaining articles A will not be disturbed or blocked by the impact of falling on the door panel 22. In addition, since the contact plate 15 includes a contact portion 15a that can be in contact with the upper surface of the article A and an engagement portion 15b that is engaged with the drop prevention plate 14, the contact plate 15 can be engaged with the drop prevention plate 14 In the state of moving, the contact plate 15 is prevented from being detached from the upper surface of the article A due to the conveying operation of the article conveying device. In addition, since the holding member 16 engaging the contact plate 15 is located on the top of the drop prevention plate 14, the article A can be stored in the article storage compartment 10 without removing the contact plate 15. This results in effective storage of article A. In addition, the detachable structure of the contact plate 15 can be removed when necessary. For example, if a thin and light article is stored, the contact plate 15 can be fitted, and -12-200535740, and when the article is very thick, its storage condition is not affected by the drop impact, so the contact plate can be omitted. 1 5. Incidentally, although the above-mentioned embodiment has a configuration in which the contact plate 15 is in contact with the article A placed highest by its own weight, it is also possible to make an article contact member by a pressing member such as a coil spring And in contact with the top of the item. In addition, although the contact plate 15 in the above embodiment is connected to the drop prevention plate 14 and can be moved in the vertical direction, it is also possible to use a connection portion 15b extending in the vertical direction and contacting the contact plate 15 When the connecting coupling coupler is installed on the partition member 11 or the side plate 12, the article contact member can be moved to ground. Moreover, although the said embodiment is comprised, the contact plate 15 is hold | maintained in the part above the article storage compartment 10 by engaging the holding member 16 connected to the contact plate 15 and the upper end of the fall prevention plate 14, However, the contact plate 15 can also be held in the upper portion of the article storage compartment 10 when the contact plate 15 is attracted by mounting a magnet on the upper end of the article storage compartment 10. ® So far, the preferred embodiments described in this specification are for illustrative purposes only, and are not meant to be limiting.
