Description
本发明涉及运输装置技术领域，具体涉及一种螺旋塔输送设备。
现有行业内使用的螺旋塔输送设备分内侧驱动和外侧驱动两种输送系统。外侧驱动的螺旋塔输送系统是指在螺旋塔的输送网链的外侧边缘，可以是一侧，也可以是多个侧面边缘，设置多组旋转齿轮，齿轮与输送网链的外侧边缘啮合旋转驱动，带动输送网链在螺旋塔轨道上输送传送。内侧驱动输送系统又分为摩擦式驱动和强制驱动两种，其中内侧强制驱动的螺旋塔输送系统是指在螺旋塔的中间部分设置一体式结构的转筒，运用电机马达驱动转筒匀速旋转。转筒圆周外侧设置辅助套直接驱动输送网链螺旋运动。转筒外侧的辅助套上有三角尖形凸起并垂直向上延伸。辅助套上的三角凸起会与输送网链的菱形端面发生抵接，切入咬合时辅助套上的三角凸起会与输送网链的菱形端面大概率情况下互相错位，顺利切入，但两个凸起的三角尖偶尔在同一位置互顶，导致出现无法错开的现象。输送网链继续向上转动，辅助套上的三角凸起对输送网链的端头产生一定压力，且当压力达到临界值时会发生输送网链的端头蹦入辅助套或者断裂现象。
当输送网链的张力逐渐增大到超过辅助套的摩擦力时，输送网链又会从辅助套上瞬间滑落，造成输送网链的跳动，现有的输送网链的端头侧面为平行平面，拨动杆为矩形形状，输送网链的端头在重载转 动或快速转动时容易脱出跳齿。

在一些可选实施例中，所述拨动杆15呈圆柱形或者D形，其侧面呈圆弧形；所述端头14呈球形，其两个侧面呈均圆弧形，使得二者之间能够圆滑过渡连接，拨动杆15和端头14连接咬合后之间没有间隙。
在一些可选实施例中，所述导向块16与所述立柱17之间采用螺栓20连接，其中，螺栓20的数量为6个，将导向块16与立柱17可拆卸地连接在一起。
在一些可选实施例中，所述孔洞163贯穿所述斜面161设置。螺旋塔输送设备还包括马达18和齿轮19，所述马达18驱动转筒11转动，当所述输送网链13在直线段时，所述输送网链13设置于所述齿轮19的上表面，当输送网链13进入螺旋塔后，输送网链13铺设在耐磨条上，耐磨条是U型结构，卡在轨道上。所述导向块16朝向所述立柱17的侧面上设有凹槽164，所述凹槽164中卡设有所述立柱17。所述凹槽164呈矩形槽，所述凹槽164的深度为所述导向块16厚度的0.3-0.8倍，导向块16的厚度是指平面162与其相对侧面之 间的最大厚度，凹槽164的厚度不易过大，否则容易导致导向块16出现断裂的情况。
螺旋塔输送设备还包括框架12，所述框架12设置于转筒11的外侧，用于支撑整个设备，所述斜面161与水平面的夹角为5-20°，如15°或者18°等，当然，斜面161与水平面的夹角也可以设置为其他角度，根据需要进行调整。
在一些可选实施例中，所述拨动杆15宽度方向的边缘与所述导向块16的边缘平齐，输送网链13的端头14顶部和立柱17之间贴合没有间隙。
在一些可选实施例中，所述拨动杆15的啮合面为斜面、弧形面、或其他任何可以啮合的形状，使得所述拨动杆15啮合面的受力方向相对于螺旋塔的转动方向向内偏移。
螺旋塔输送设备可根据实际应用的环境高度和输送产品的高度，设计不同的塔高和层高。一座螺旋塔输送设备一般设计有十几层。
输送网链13首先从螺旋塔外的直线部分通过，然后进入螺旋塔输送设备的入口贴着导向块16的平面162滑动，在螺旋塔第一层圆形轨道上运行大于1/4圆周后滑入拨动杆15和导向块16的斜面161，沿斜面161渐渐滑入啮合拨动杆15的位置形成互扣结构。
输送网链13的端头14的最外部设置成圆弧形，这样同拨动杆15的高点随机相遇时，使输送网链13滑离拨动杆15，更加容易进入拨动杆15的啮合位置。其中，拨动杆15的啮合位置有两个，分别位于其两侧。
输送网链13的端头14的左右两个侧面也是一个内凹的圆弧形，与拨动杆15的圆形弧度啮合后产生一种互扣结构。
此外，立柱17沿着转筒11圆周的框架12均匀分布。每根立柱17都固定连接一个导向块16。拨动杆15也可以平行焊接到立柱17上。需要指出的是，不是每根立柱17、每个导向块16都连接拨动杆15。全部连接拨动杆15也是可以的，但是实际应用中，拨动杆15间隔布置，约占立柱17的1/3数量，均匀布置即可实现功能需要。
拨动杆15的高度从输送网链13的入口高度1/4螺旋层高位置开始，到距离螺旋塔最顶层轨道约1/8层高位置结束。拨动杆15的一端连接在导向块16的斜面161上，另一端切割成贴合立柱15的斜面状，从正面看形成一个尖头的楔形，再折弯成与立柱17平行后焊接在立柱17上。拨动杆15的末端也是一个斜面，输送网链13沿着拨动杆15滑动，自然顺着斜面从拨动杆15上滑脱。拨动杆15末端的斜面也起到扩大轨道宽度的作用。输送网链13的内侧从收拢状态沿着螺旋塔轨道逐渐变成张紧状态，这样进入直线段时，输送网链13的内外两侧的张力恢复到一样。
输送网链13从螺旋塔输送设备上沿着轨道传送到出口时，输送网链13在螺旋塔输送设备的转筒11上距离出口还有一段行程时，逐渐脱离拨动杆15，从螺旋塔出口出来进入螺旋塔输送设备的回程直线段。
所述输送网链13进入所述转筒11的1/4至1/2圆周后渐入所述拨动杆15，所述输送网链13在旋出所述转筒11前1/4圆前旋出所 述拨动杆15的端头。
在实施例中，所述输送网链13从导向块16的平面162滑动到斜面161，沿所述拨动杆15的外周渐渐进入，咬合所述拨动杆15，进入方式是由外向内，实现平滑过渡。
螺旋塔输送设备能够有效的解决内侧驱动单筒螺旋塔的入口的技术问题，输送网链13在入口处自由进入，进入转筒11的1/4-1/2后才渐渐进入拨动杆15的位置，避免了拨动杆15阻碍内侧链节进入的问题，输送网链13在转筒11上的外侧受力，内侧网链堆积，受直线段网链牵引拉力影响，内侧网链与外侧网链不能同时进入转筒11的圆弧，如果在入口位置凸台就起到驱动作用，会造成内侧堆积的输送网链11的实际长度达不到外侧网链的弧长，造成外侧网链实际长度不够，这也正是网链过度张紧的原因。
本发明解决的技术问题的方法是，输送网链13沿导向块16平面进入转筒11，内侧网链堆积(这个阶段的应用状态类似于摩擦式结构)。受外侧拉力影响，输送网链13的内侧转动一定角度后会滑动到同外侧网链相应位置，输送网链13在进入入口后沿导向块16的平面旋转1/4至1/2圆后再进入拨动杆15，这个状态的网链内外侧位置同步，避免了上述内侧网链长度不足造成外侧网链达不到实际需求长度，避免输送网链由于张力过大造成的断裂。
松弛状态的输送网链13自由的随机滑入导向块16和拨动杆15，转筒11的圆周平面上形成输送网链对称的分布。输送网链13的端头和拨动杆15互扣结构，解决了转筒11将输送网链13向外推的受力 结构问题，使输送网链13的端头受力向内(向圆心)。辅助套结构的拨动杆15的弧形面和输送网链13的端头的弧形面互扣咬合，并且输送网链13的端头贴紧立柱17的表面，输送网链13被拨动杆15勾住，不会从辅助套结构上向内向外脱离，输送网链13也就不会发生跳动。
输送网链13在旋出所述转筒11前1/4圆前旋出所述拨动杆15的端头，使出口处输送网链13脱离啮合的拨动杆15，保证了旋出顺利。
虽然，上文中已经用一般性说明及具体实施例对本发明作了详尽的描述，但在本发明基础上，可以对之作一些修改或改进，这对本领域技术人员而言是显而易见的。因此，在不偏离本发明精神的基础上所做的这些修改或改进，均属于本发明要求保护的范围。
