本发明节省了工序之间衔接的步骤， 纸板压板和折箱同步进行， 有效节省了工作时间， 人 力成本大幅降低； 纸箱制作过程中误差减小， 并有效提高了纸箱的成品率； 本发明因为可以使 链条反转并有静止的时间， 因此压箱环节可以与折箱环节一体化设计， 同步进行， 节省工序和 成本， 提高了效率； 传统的钉箱机在钉箱时纸箱停顿时间极短， 因此钉箱的效果不理想， 废品 率相对较高； 本发明因为可以使链条反转并有静止的时间， 因此钉箱环节废品率低， 而且与压 箱环节可以与折箱环节一体化设计， 同步进行， 节省工序和成本， 显著提高了效率。

具体实施方式
下面结合附图详细说明本发明的优选实施例。
下面结合附图对本发明的技术方案做进一步的说明， 但不应理解为对本发明的限制： 图 1是本发明的结构示意图， 图 2是未折叠的纸板示意图， 图 3是机械臂未折叠时的结构 示意图， 图 4是机械臂折叠时的结构示意图， 结合图 1、 图 2、 图 3、 图 4所示， 具体包括链 条驱动轴 1、 纸板输送挡块 3、 多个纸板输送挡块 3等距离固定设置于链条 2上， 机械臂 4以 及定位挡板 5， 链条驱动轴 1上挂有多排链条 2,用于传送纸板 25的链条 2与反转电机相连， 当链条 2前进一定距离 S1后， 正转电机停转， 反转电机运转， 使链条后退一小段距离 S2后， 静止一段时间 T; 纸箱制造装置从上游到下游依次包括进纸部 I、 折箱部 IV、 以及钉箱粘箱部
VI， 具体包括链条驱动轴 1、 链条 2、 纸板输送挡块 3、 机械臂 4以及定位挡板 5， 链条驱动轴
1上挂有多排链条 2， 使用中， 链条 2为 2排或 3排或 4排， 多个纸板输送挡块 3等距离设置 于链条 2上， 链条 2在链条驱动轴 1的驱动下旋转， 纸板输送挡块 3用于勾住纸板 25在生产 线上前行， 机架两侧设置有机械臂 4， 机械臂 4的前方设有定位挡板 5。 当纸板输送挡块 3带 动纸板 25运行到定位挡板 5处时， 纸板输送挡块 3停止并后退， 后退一定距离后链条停转一 定的时间，此时纸箱折叠装置对纸箱进行折叠； 也可以设计成纸箱压线装置对纸箱进行压线处 理， 纸箱折叠装置对纸箱进行折叠， 钉箱装置对纸箱进行钉箱， 三个装置同步进行工作； 现有技术的装置， 链条一直向前转， 而且在纸板进行压板前要保持一个比较快的速度， 在 较快的速度下， 以及在链条摩擦力的带动下， 使得输送挡块与纸板之间分离， 并使纸板与挡块 之间有一定的距离， 因此在折箱过程中， 折叠臂下降折叠纸板时不会碰到输送挡块； 本发明和 现有技术的区别是， 当纸板 25前进到达折箱部 II的定位挡板 5时， 纸板输送挡块 3停止并后 退， 后退的距离大于挡块本体 9顶端凸起 10的宽度， 后退后， 使得纸板输送挡块 3避免了被 落下的纸板 25撞到， 保护纸板输送挡块 3不被损坏， 也不会影响纸箱的正常折叠， 因为折叠 时纸板是静止不动的， 因此也使得纸箱的成品率提高。 现有技术的纸箱首先要在压箱机上进行压线工序，压线工序结束后， 再人工搬运到折箱机 上进行折箱， 这样原来的工序就比较繁琐， 费时而且不利于人力成本的节约， 本发明因为可以 使链条反转并有静止的时间， 链条 2静止一段时间 T优选为 0.05-0.5秒。 因此压箱环节可以 与折箱环节一体化设计， 即压线环节与折叠环节都在同一台机器上进行， 并且紧密对接， 沿线 步骤与折箱步骤在链条停顿时同步进行， 节省工序和成本， 提高了效率。
传统的钉箱机在钉箱时纸箱停顿时间极短， 因此钉箱的效果不理想， 废品率相对较高； 本 发明因为可以使链条反转并有静止的时间， 因此钉箱环节废品率降低， 而且钉箱环节与压箱环 节可以与折箱环节一体化设计， 在链条停顿的时刻同步进行， 节省工序和成本， 提高了效率。
本实施例中机械臂 4对纸板进行折叠， 伺服电机一 6和伺服电机二 7， 链条驱动轴 1和伺 服电机一 6的输出轴之间通过皮带连接， 这样， 链条驱动轴 1由单独的伺服电机一 6驱动。机 械臂 4分为操作侧的机械臂 4a和驱动侧的机械臂 4b两种， 操作侧的机械臂 4a和驱动侧的机 械臂 4b分别位于机架的两侧且和机架之间通过轴连接， 使得机械臂 4可以上下自由活动， 操 作侧的机械臂 4a和驱动侧的机械臂 4b向内折进即可对纸板 25进行折叠， 两种机械臂 4分别 和伺服电机二 7相连接，伺服电机二 7可分别对操作侧的机械臂 4a和驱动侧的机械臂 4b进行 控制， 操作侧的机械臂 4a的驱动速度稍大于驱动侧的机械臂 4b的驱动速度， 或者是操作侧的 机械臂 la的驱动时间稍早于驱动侧的机械臂 lb的驱动时间， 使得折叠时， 是操作侧的机械臂
4a先下降， 驱动侧的机械臂 4b后下降， 保证折叠出的纸板 25的一端折叠到另一端的上面， 满足后续钉箱的需要。 由于链条驱动轴 1和机械臂 4都由单独的伺服电机驱动， 改变了现有技 术中整个生产线都由导向杆和传送带控制慢慢折叠， 折叠误差较大精度差， 结构复杂的现状， 使得整个生产线的造价大大降低， 适合中小企业的安装使用。
机械臂 4的两端向前折起，使得机械臂 4形成向内的空间。机械臂 4可以是铁皮或者铁板 制成， 形状不限， 而且本装置中的机械臂 4具有向内的空间， 这样当机械发生故障时， 纸板输 送挡块 3可以从机械臂 4的向内的空间穿过或所述的机械臂 4对应纸板输送挡块 3的部位设有 相应的凹槽， 防止撞坏机械臂 4。
为了对机械臂 4在折进或者折出时超出行程，在机械臂 4和机架之间的轴的一侧装有限位 挡块 8， 对机械臂 4的行程进行控制。
使用时， 如图 2所示， 未折叠的纸板 25分为四个部分， 分别为 A部分、 B部分、 C部分、 D部分， A部分和 D部分为纸板 25的两端。 当纸板输送挡块 3勾住纸板 25输送并定位至折 箱部 IV机械臂 4部分时，此时的状态如图 3所示，然后操作侧的机械臂 4a和驱动侧的机械臂 4b在伺服电机二 7的驱动下向内折进， 操作侧的机械臂 4a先下降， 驱动侧的机械臂 4b后下 降， 使得纸板 25的 A部分被折叠在 D部分的下面， 此时的状态如图 4所示， A部分和 D部 分相互重合的部分用于后续钉箱部进行钉箱或者粘箱工作。
图 5是纸板输送挡块的结构示意图， 如图所示， 所述的纸板输送挡块 3， 包括挡块本体 9， 挡块本体 9的顶端有向前突出的凸起 10。凸起 10的存在使得纸板输送挡块 3可以勾住纸板 25 进行运送， 防止纸板脱开。
由于链条 2在长时间使用后， 可能会发生松动， 此时容易造成折叠完毕的的纸板 25上下 层对不齐。 因此， 挡块本体 9的侧面在位于凸起 10下方的部分具有轻微向内的倾斜， 这样使 得纸板输送挡块 3卡住纸板 25时更加牢固， 即使链条 2松动后， 也能保证折叠完毕的的纸板 25上下层对齐，严格保证纸箱的质量。倾斜的程度非常小， 以不影响纸板 25的正常折叠为宜。
图 6是纸箱压线装置的结构示意图， 图 7是图 6的侧视图， 结合图 6、 图 7所示， 还包括 压线部 II， 该装置分为两套， 分别位于机架的左右两侧， 每套都包括气缸一 11、 压痕板 12以 及托板 13， 气缸一 11的下端装有压痕板 12， 压痕板 12的底部有尖刃； 压痕板 12和托板 13 分别位于机架的上下两侧， 且压痕板 12和托板 13的位置相对。 由气缸一 11驱动压痕板 12的 上升或者下降， 气缸一 11受空气压縮机的控制， 压痕板 12的作用是对纸板 25进行压线， 由 于压痕板 12和托板 13的位置相对， 托板 13的作用是托住纸板 25， 与压痕板 12—起， 对纸 板 25上下夹击， 进行压线。
为了保证压痕板 12每次上升或者下降运动过程中位置的精确性，在压痕板 12两端装有导 向块 14， 这样可以保证压线的精确性， 保证纸箱的质量。 生产时， 如图 2所示， 纸板 25上有左压痕线 28和右压痕线 29， 当纸板 25被纸板输送挡 块 3运送到达此本装置时停顿片刻， 空气压縮机将压縮空气打入气缸一 11， 气缸一 11驱动压 痕板 12下降， 并用尖刃部位挤压左压痕线 28和右压痕线 29， 使其压线充分。 当压线处理完 毕后， 空气压縮机将压縮空气抽出气缸一 11， 气缸一 11驱动压痕板 12上升， 纸板 25继续前 行进入下一道工序， 如此往复循环。
图 8是纸箱挤压装置的结构示意图， 图 9是图 8中 A-A向示意图， 图 10是图 8中 B-B向 示意图， 图 11是图 8中 C-C向示意图， 图 12是图 8中 D-D向示意图， 图 13是图 8中 E-E向 示意图， 结合图 8至图 13所示， 还包括挤压部 III， 该装置分为两套， 分别位于机架的左右两 侧， 每套都包括若干组上挤压轮 15和下挤压轮 16， 上挤压轮 15和下挤压轮 16分别位于机架 的上下两侧， 下挤压轮 16的上缘为倾斜的钝角， 且多个下挤压轮 16按照倾角从大到小依次排 列， 上挤压轮 15的轮尖正好对准下挤压轮 16钝角的回折处。 纸板 25正好能够从上挤压轮 15 和下挤压轮 16之间的空间通过， 上挤压轮 15的轮尖正好压在压线处， 由于多个下挤压轮 16 按照倾角从大到小依次排列， 这样纸板 25在前进的过程中， 纸板 25的两端会被多个下挤压轮 16慢慢沿着压线抬起， 抬起的过程为纸板 25从图中 E位置变化到 A位置的过程。
为了使得折叠时更加方便， 上挤压轮 15为倾斜放置， 与下挤压轮 16—起共同作用将纸板 25沿着压线抬起。
如图 2所示， 纸板 25折叠过程中要求必须沿着左压痕线 28和右压痕线 29进行折叠。 纸 板 25在通过上挤压轮 15和下挤压轮 16之间的空间时，倾斜放置的上挤压轮 15轮尖抵住左压 痕线 28和右压痕线 29， 由于下挤压轮 16角度逐渐变小， 慢慢托起纸板 25的两端， 且上挤压 轮 15轮尖对准下挤压轮 16的角度部位， 所以纸板 25只会沿着压痕部位折叠， 大大减少了误 差。
图 14是纸箱对齐装置的结构示意图， 如图所示， 还包括间隙调整部 V， 间隙调整部 V位 于折箱部 IV的下游， 间隙调整部 V包括纸箱对齐装置， 具体包括气缸二 17和拍齐挡板 18， 气缸二 17的前端装有拍齐挡板 18， 拍齐挡板 18垂直悬挂在链条 2的上方。 气缸二 17受到空 气压縮机的控制， 通过气缸二 17驱动拍齐挡板 18的上升或者下降。
生产时， 当机械臂 4折叠后的纸板 25通过纸板输送挡块 3由链条 2驱动运行到间隙调整 部 V时， 空气压縮机将压縮空气打入气缸二 17， 气缸二 17驱动拍齐挡板 18下降， 纸板 25前 部到达拍齐挡板 18， 此时， 纸板输送挡块 3停止， 拍齐挡板 18即可对纸板 25的上下层进行 拍齐处理， 防止因为纸板 25的上下层对不齐而使纸箱报废； 当拍齐处理完毕后， 空气压縮机 将压縮空气抽出气缸二 17， 气缸二 17驱动拍齐挡板 18上升， 纸板输送挡块 3继续向前运动， 处理后的纸板 25得以顺利通过， 进入下一步工序。
图 15是钉丝输送机构的结构示意图， 图 16是图 15的侧视图， 结合图 15、 图 16所示， 所述的钉箱粘箱部 VI包括钉丝输送机构， 具体包括钉丝卷 19、 送丝电机 20和限位开关 21， 钉丝卷 19上缠绕有钉丝 22， 钉丝 22用于将纸板钉成纸箱。 钉丝卷 19位于送丝电机 20的上 方， 限位开关 21位于送丝电机 20的下方， 限位开关 21与送丝电机 20之间为电连接； 钉丝 22从钉丝卷 19伸出， 绕过送丝电机 20和限位开关 21后向上伸出。 因此， 由限位开关 21控 制送丝电机 20的启动与否，当钉丝 22从限位开关 21的下方的下钉丝位 27运动到上方的上钉 丝位 26时， 即可打开限位开关 21， 从而启动送丝电机 20， 带动钉丝 22从钉丝卷 19上再伸出 一段。
为了使钉丝 22能够顺利输送到钉机头， 还包括导向钢管 23， 导向钢管 23竖直设置， 钉 丝 22绕过限位开关 21后向上从导向钢管 23穿出， 对钉丝 22的运动轨道进行控制。
为了防止钉丝 22在运动过程中发生偏移， 在限位开关 21处装有两个防偏挡条 24， 钉丝 22正好从两个防偏挡条 24之间通过， 进一步对钉丝 22的运动轨道进行控制。
使用时， 由于不停地地钉箱， 需要不断地消耗钉丝 22， 因此， 钉丝 22从限位开关 21的 下方的下钉丝位 27运动到上方的上钉丝位 26时， 即可打开限位开关 21， 从而启动送丝电机 20， 带动钉丝 22从钉丝卷 19上再伸出一段， 此时， 拉长后的钉丝 22重新回到限位开关 21 的下方的下钉丝位 27， 进行新一轮循环。
一种纸板成箱制造装置制造纸箱的方法， 包括进纸部进纸步骤； 压线部压线步骤； 挤压步 挤压步骤；折箱部折箱步骤；粘箱部粘箱步骤，纸板输送挡块 3后退并停止时压线部压线步骤、 折箱部折箱步骤、 粘箱部粘箱步骤三工序同步进行； 生产时， 伺服电机一 6驱动链条驱动轴 1 转动， 进而驱动链条 2发生转动， 纸板输送挡块 3带动纸板 25前进一段距离后， 伺服电机一 6停转， 链条 2由反转电机带动反转一段距离后静止一段时间， 此时由纸箱压线装置进行压线 处理， 保证压线充分。 然后经过纸箱挤压装置， 使得纸板 25沿着压线慢慢抬起， 保证后续折 叠时严格按照压线折叠， 保证纸箱质量； 当前进到达折箱部 IV的定位挡板 5时， 伺服电机一 6停转， 链条 2由反转电机带动反转一段距离后静止一段时间， 此过程中纸板输送挡块 3随链 条 2停止并后退， 后退的距离大于挡块本体 9顶端凸起 10的宽度， 后退后， 使得纸板输送挡 块 3避免了被落下的纸板 25撞到， 保护纸板输送挡块 3不被损坏， 也不会影响纸箱的正常折 叠； 在链条 2静止的时间， 机械臂 4对纸板 25进行折叠， 然后纸板输送挡块 3随链条 2继续 前进， 将折叠后的纸板 25运送到间隙调整部 III， 对纸板 25的上下层进行拍齐处理， 提高纸 箱的合格率。然后， 纸板 25被运送到钉箱粘箱部 VI， 进行装订或者粘贴， 伺服电机一 6停转， 链条 2由反转电机带动反转一段距离后静止一段时间， 最终， 在钉丝输送机构的帮助下， 用钉 丝将纸板 25订成纸箱即成； 因为链条 2上有多处输送挡块 3， 纸板 25在链条 2上输送挡块 3 的牵引下， 其压线部压线步骤、 折箱部折箱步骤、 粘箱部粘箱步骤三工序同步进行。
