Description

Technical Field

[0001] This utility model relates to the technical field of tissue boxing equipment, specifically to a material handling device for a tissue boxing machine. Background Technology

[0002] Paper towels are a common item used in daily life and work. To facilitate storage and transportation, paper towel manufacturers need to pack multiple packs of paper towels into boxes.

[0003] A tissue packing machine is a device used to grab stacks of tissues and pack them into boxes. The material handling device is the component that directly performs the action of grabbing and packing stacks of tissues. During the tissue conveying process, single packs of tissues are often conveyed. The material handling device usually stacks multiple packs of tissues together, then clamps the bottom layer of tissues to grab the entire stack of tissues and load it into the packaging box, thus completing the tissue grabbing and packing action.

[0004] However, due to issues with the raw materials used in paper towel production, there is a significant difference in volume between packs of paper towels of the same weight. For example, paper raw materials are usually in the form of paper rolls. During the winding process, the paper closer to the center is compressed more. Therefore, after producing a whole pack of paper towels with the same number of sheets and weight, the closer the sheets are to the center, the smaller the volume of the whole pack. Conversely, the closer the sheets are to the outer edges, the larger the volume of the whole pack. This results in a certain difference in the volume of each pack of paper towels.

[0005] Based on the above situation, when grabbing a stack of tissues, if the tissues on the bottom layer are smaller than those on top, the grabbing device can only hold the larger tissues due to the obstruction and restriction of the larger tissues. The smaller tissues below cannot be grabbed, which will seriously affect the efficiency of grabbing and packing the tissues.

[0006] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0007] The purpose of this utility model is to provide a material handling device for a tissue box packing machine to solve the above-mentioned technical problems. The utility model adopts the following technical solution: A paper towel packing machine's material handling device includes a conveying mechanism capable of transporting paper towels in both horizontal and vertical directions. A material handling mechanism for gripping paper towels is also provided on the conveying mechanism. The material handling mechanism includes: The mounting frame is mounted on the transfer mechanism and reciprocates in the horizontal and vertical directions under the drive of the transfer mechanism. A clamping assembly is movably mounted on the mounting frame for clamping stacks of tissues. The clamping assembly includes at least two clamping rods distributed at equal angles on the mounting frame, and all the clamping rods have a compensating member at their ends. The compensating member has a protruding portion that protrudes toward the inside of the clamping rod, and the protruding portion is used to clamp the bottom layer of tissues in the stack.

[0008] Furthermore, the clamping assembly also includes a drive unit mounted on the mounting bracket and pulsatorically connected to the at least two clamping rods, the drive unit driving all the clamping rods to reciprocate toward the center direction to clamp or release a stack of tissues.

[0009] Furthermore, the compensation element is defined as a block formed on the end of the clamping rod, one end of the block protruding toward the inside of the clamping rod to define the protruding portion.

[0010] Furthermore, the compensation element is defined as a sleeve fitted onto the end of the clamping rod, the portion of the sleeve located inside the clamping rod defining the protruding portion.

[0011] Furthermore, the protruding portion is provided with an anti-slip structure.

[0012] Furthermore, the clamping rod includes: A sliding member, which forms a sliding pair with the mounting frame and is slidably disposed on the mounting frame along a straight line; A rod is fixedly mounted on the sliding member and extends downward in a vertical direction, and a compensation member is disposed at the lower end of the rod.

[0013] Furthermore, the driving unit includes a driving component and a transmission component. The driving component is connected to the sliding component through the transmission component, so as to drive all the sliding components to reciprocate along a straight line simultaneously.

[0014] Furthermore, the transmission component is fixedly mounted on the output shaft of the drive component and is driven to rotate by the drive component. The surface of the transmission component is formed with a plurality of cam grooves corresponding to the sliding component, and the sliding component is provided with a pulley that is slidably connected within the cam grooves.

[0015] Furthermore, the transfer mechanism includes a first linear module arranged in a horizontal direction, and a second linear module arranged in a vertical direction is arranged on the first linear module. The clamping assembly is arranged on the second linear module and reciprocates along the horizontal and vertical axes under the drive of the first and second linear modules.

[0016] The beneficial effects of this utility model are as follows: In the process of grasping tissues, tissues are usually transported in single packs. To improve packing efficiency, the picking device provided in this embodiment stacks a predetermined number of single packs of tissues together, and then clamps the tissues at the bottom layer, thereby picking up the entire stack of tissues and transferring them into the packaging box, completing the tissue picking and packing action. During the process of grasping the stack of tissues, the protruding part of the compensating member extending inward toward the clamping rod can compensate for the size of the smaller tissues, allowing the compensating member to reliably clamp the bottom layer of tissues, and the clamping rod will not be interfered with by the larger tissues at the top, thereby achieving reliable clamping of the entire stack of tissues, and completing the packing action of the tissues under the drive of the transfer mechanism.

[0017] The technical solution provided in this embodiment can clamp the bottom layer of the stack of tissues under the action of the compensation component, thereby grabbing the entire stack of tissues. The stack of tissues is also restricted by the clamping rod to prevent tilting. This technical solution can reliably clamp the entire stack of tissues, thereby quickly and reliably completing the packing of tissues and ensuring the reliability and efficiency of tissue packing.

[0022] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0023] This utility model provides a material handling device for a tissue packing machine, used to grab tissues and load them into a packaging box. Specifically, this device can grab stacks of tissues, and the compensation member 212 set on the clamping rod 211 can compensate for the smaller tissues at the bottom, thereby reliably clamping the bottom layer of tissues. This allows the stack of tissues to be grabbed and loaded into the packaging box. The technical solution provided by this embodiment can reliably grab and pack stacks of tissues, thereby ensuring the efficiency and reliability of tissue packing.

[0024] Specifically, such as Figure 1-3 As shown, this utility model embodiment provides a paper towel packing machine material handling device, including a conveying mechanism 100 capable of transporting in both horizontal and vertical directions. A material handling mechanism 200 for gripping paper towels is also provided on the conveying mechanism 100. The material handling mechanism 200 includes a mounting frame 201 and a clamping assembly 210. The mounting frame 201 is mounted on the conveying mechanism 100 and reciprocates in both horizontal and vertical directions under the drive of the conveying mechanism 100. The clamping assembly 210 is movably mounted on the mounting frame 201 for clamping stacked paper towels. The clamping assembly 210 includes at least two clamping rods 211 distributed at equal angles on the mounting frame 201, and each clamping rod 211 has a compensation member 212 at its end. The compensation member 212 has a protruding portion 2121 protruding towards the inside of the clamping rod 211, and the protruding portion 2121 is used to clamp the bottom layer of the stacked paper towels.

[0025] In the process of grasping tissues, tissues are typically conveyed in single packs. To improve packing efficiency, the material-grabbing device provided in this embodiment stacks a predetermined number of single packs of tissues together, then clamps the bottom layer of tissues, thereby grasping the entire stack of tissues and transferring it into the packaging box, completing the tissue-grabbing and packing action. The material-grabbing device provided in this embodiment is used to grasp and pack rolls of tissues. Figure 4The diagram shows the structure of the material-grabbing device provided by this utility model in the material-grabbing state. It is used to grab and pack four stacks of tissues. Therefore, in this embodiment, four clamping rods 211 are provided at equal angular intervals. In other embodiments, two clamping rods 211 can be provided to grab a stack of square-packaged tissues, or three, five, or six clamping rods 211 can be provided to grab the tissues. During the grabbing of the stack of tissues, the protruding portion 2121 of the compensating member 212 extending towards the inside of the clamping rod 211 can compensate for the smaller tissues, ensuring that the compensating member 212 reliably clamps the bottom layer of tissues. Furthermore, the clamping rod 211 is not interfered with by the larger tissues located above, thus achieving reliable clamping of the entire stack of tissues. The tissues are then packed into boxes under the drive of the transfer mechanism 100.

[0026] The technical solution provided in this embodiment can clamp the tissues at the bottom of the stack under the action of the compensation member 212, thereby grabbing the entire stack of tissues. The stack of tissues is also restricted by the clamping rod 211 to prevent tilting. This technical solution can reliably clamp the entire stack of tissues, thereby quickly and reliably completing the packing of tissues and ensuring the reliability and efficiency of tissue packing.

[0027] In this embodiment, the compensating member 212 is a sleeve fitted onto the end of the clamping rod 211, and the portion of the sleeve located inside the clamping rod 211 defines the protruding portion 2121. That is, by fitting a sleeve onto the end of the clamping rod 211, the diameter of the end of the clamping rod 211 can be increased. During the clamping of a stack of tissues, because the diameter of the end of the clamping rod 211 is larger, the portion of the sleeve located inside the clamping rod 211 can compensate for the size of the smaller tissues in the lower layer, thereby achieving reliable clamping on the bottom layer of tissues and ensuring reliable clamping, picking, and packing of the entire stack of tissues.

[0028] In other embodiments, the compensation member 212 may also be composed of a block formed on the end of the clamping rod 211, one end of which protrudes toward the inside of the clamping rod 211 to define a protruding portion 2121. By forming the block on the end of the clamping rod 211 and providing the protruding portion 2121 extending toward the inside of the clamping rod 211, it is possible to clamp the smaller lower layer of tissue paper.

[0029] To further improve the reliability of holding the tissue, an anti-slip structure is provided on the protruding part 2121. The anti-slip structure can be an anti-slip pad or other structures.

[0030] In this embodiment, the clamping assembly 210 further includes a drive unit 220 mounted on the mounting bracket 201 and pulsatorically connected to at least two clamping rods 211. The drive unit 220 drives all the clamping rods 211 to reciprocate toward the center direction to clamp or release a stack of tissues.

[0031] The drive unit 220 is connected to the clamping rod 211 for transmission, so that the clamping rod 211 can perform clamping or releasing actions, thereby realizing the clamping or releasing of stacks of paper towels.

[0032] In this embodiment, the clamping rod 211 includes a sliding member 2111 and a rod 2112. The sliding member 2111 and the mounting frame 201 form a sliding pair and are slidably disposed on the mounting frame 201 along a straight line. In this embodiment, the sliding member 2111 is a slide rail, and a slider that forms a sliding pair with the slide rail is fixedly mounted on the mounting frame 201. In other embodiments, the sliding member 2111 can be a slider, and correspondingly, a slide rail is provided on the mounting frame 201 for the slider to slide along a straight line. The rod 2112 is fixedly mounted on the sliding member 2111 and extends downward in the vertical direction. The compensating member 212 is disposed at the lower end of the rod 2112.

[0033] Meanwhile, the drive unit 220 includes a drive member 221 and a transmission member 222. The drive member 221 is connected to the sliding member 2111 through the transmission member 222, so as to drive all the sliding members 2111 to reciprocate along a straight line simultaneously. In this embodiment, the drive member 221 can be a motor. The motor is connected to all the sliding members 2111 through the drive member 221, so as to drive all the clamping rods 211 to move along a straight line, thereby realizing the clamping or releasing action.

[0034] Specifically, such as Figure 3 As shown, the transmission component 222 is fixedly mounted on the output shaft of the drive component 221 and is driven to rotate by the drive component 221. Several cam grooves 2221 corresponding to the sliding component 2111 are formed on the surface of the transmission component 222, and a pulley 2113 with a limit and sliding connection is provided on the sliding component 2111 within the cam groove 2221.

[0035] During the clamping action of the driving clamping rod 211, the transmission component 222 is fixedly mounted on the output shaft of the driving component 221. That is, the transmission component 222 can rotate under the drive of the motor. At this time, the pulley 2113 of the sliding component 2111 is limited and slidably connected in the cam groove 2221 of the transmission component 222. During the rotation of the transmission component 222, the pulley 2113 is limited and slid in the cam groove 2221, thereby driving the sliding component 2111 to move in a straight line, thereby completing the clamping and releasing action.

[0036] By employing a cam structure to achieve linear drive of the clamping rod 211, the accuracy and reliability of the clamping rod 211 in driving can be guaranteed, and there will be no loosening, thereby ensuring the reliability of picking up stacks of paper towels.

[0037] In this embodiment, a specific example of the structure of the transfer mechanism 100 is given. The transfer mechanism 100 includes a first linear module 101 arranged in the horizontal direction, and a second linear module 102 arranged in the vertical direction is arranged on the first linear module 101. The clamping component 210 is arranged on the second linear module 102 and reciprocates along the horizontal and vertical axes under the drive of the first linear module 101 and the second linear module 102. The transfer mechanism 100 is formed by two linear modules, which can drive the material gripping mechanism 200 to reciprocate, thereby realizing the material picking and loading action. In other embodiments, three linear modules can be arranged to realize movement along three axes (horizontal and vertical), thereby improving the adaptability of the material picking device.

Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
