Description

Technical Field

[0001] The utility model relates to the technical field of cardboard feeding equipment, and particularly relates to an automatic feeding device for cardboard products. Background Art

[0002] Most of the existing paper boxes are formed by folding, edging and bonding single-layer cardboard. To ensure the production efficiency of paper boxes, most of the existing paper boxes are produced by assembly lines. During the production process of paper boxes, the cardboard after pretreatment such as blanking and forming needs to be moved to the paper box production assembly line. In the prior art, each production line is equipped with an operator to load the product main body at the head of the production line. Among them, most of the product main body loading has high requirements for positioning accuracy. However, the loading positioning depends entirely on manual alignment by the edge, which has a great risk of deviation. When the product main body (cardboard) is loaded with deviation, subsequent processes such as dispensing and sticking cards will all be deviated, resulting in product scrapping.

[0039] It should be understood that this embodiment also includes a frame 400, and the conveying assembly 100 is installed on the frame 400. Installing the conveying assembly 100 on the frame 400 facilitates the placement of the cardboard stacks 500 and the layout of other components. The frame 400 is usually made of aluminum alloy profiles or other profiles connected by lapping. At the same time, the rectifying assembly 200 and the picking assembly 300 are also installed on the frame 400.

And the table surface of the conveying assembly 100 is higher than the table surface of the frame 400 on which the conveying assembly 100 is installed. The table surface of the conveying assembly 100 is higher than the table surface of the frame 400 on which the conveying assembly 100 is installed (the profile rack / plate on both sides of the belt line), so that the material (product body) can move with the rotation of the belt line.

After the materials are full, the operator can move to other lines to load the materials. According to the size of the product body, the operator can load two or three production lines at the same time, or even more production lines.

[0042] Combination Figure 4 The deflection correction component 200 includes: a deflection correction base plate 210, which is used to receive the cardboard released by the material taking component 300; and a plurality of deflection correction positioners 220, which are arranged on each side of the deflection correction base plate 210, and each of the deflection correction positioners 220 can push the cardboard toward the inner side of the deflection correction base plate 210. The plurality of deflection correction positioners 220 are arranged on each side of the deflection correction base plate 210, so that the cardboard on the deflection correction base plate 210 is automatically centered and positioned by the simultaneous action of the plurality of deflection correction positioners 220, so as to ensure the consistency of the cardboard sent to the next process.

[0043] Combination Figure 5 Specifically, the deflection correction positioner 220 includes: a positioning linear driver 221; a positioning push plate 222, the positioning push plate 222 is connected to the deflection correction positioning linear driver 221, and the positioning push plate 222 is used to push the cardboard. The positioning linear driver 221 drives the push cardboard to move, which can center the cardboard on the one hand, and on the other hand, the deflection correction component 200 can position the multifunctional cardboard of the specification, and has good compatibility.

[0044] Generally speaking, the deflection correction base plate 210 is a rectangular structure, and deflection correction positioners 220 are provided on both sides of the deflection correction base plate 210 in the width direction, and the movement direction of the deflection correction positioner linear actuators 221 of the two deflection correction positioners 220 in the width direction is parallel to the length direction of the deflection correction base plate 210. At the same time, deflection correction positioners 220 are provided on both sides of the length direction of the deflection correction base plate 210, and the movement direction of the deflection correction positioner linear actuators 221 of the two deflection correction positioners 220 in the length direction is parallel to the width direction of the deflection correction base plate 210. In this embodiment, two deflection correction positioners 220 are adapted to the length direction side of the deflection correction base plate 210, and are located at both ends thereof.

[0045] Of course, the deflection correction base plate 210 can also have other polygonal structures. The positions of the positioning linear driver 221 and the positioning push plate 222 of the deflection correction and positioning assembly can be adjusted according to the product size, which not only ensures the consistency of the deflection correction and positioning, but also can be compatible with products of various sizes. For the positioning linear driver 221, a cylinder is usually used, and of course, an electric push rod, a linear motor, and a linear drive mechanism driven by a rotary motor can also be used.

[0046] Combination Figure 2 , Figure 4 and Figure 5 The picking component 300 includes: a longitudinal linear drive 310; a picking mechanism, which is transmission-connected with the longitudinal linear drive 310, so that the picking mechanism is driven to reciprocate above the discharge end of the conveying component 100 and the deflection correcting component 200 through the movement of the longitudinal linear drive 310, so that the picking component 300 can send the cardboard into the deflection correcting component 200 and send the cardboard positioned by the deflection correcting component 200 to the next process processing equipment.

[0047] Specifically, the longitudinal linear drive 310 is a linear motor module to simplify the structure of the longitudinal linear drive 310 while ensuring that the longitudinal linear drive 310 has a sufficient driving distance. Of course, an electric push rod, a cylinder, and a linear drive mechanism driven by a rotary motor can also be used as the longitudinal linear drive 310.

[0048] Among them, the material picking mechanism includes: a conveying and picking mechanism 320, which is used to clamp the cardboard on the discharge end of the conveying component 100; a loading and picking mechanism 330, which is used to clamp the cardboard on the correcting component 200, so that the picking mechanism can clamp the cardboard on the discharge end of the conveying component 100 and the cardboard on the correcting component 200 respectively.

[0049] In this embodiment, the conveying and picking mechanism 320 includes: a first vertical linear drive 321, which is transmission-connected to the longitudinal linear drive 310; a first picking clamp 322, which is arranged at the lower end of the first vertical linear drive 321, and the first picking clamp 322 can clamp the cardboard on the discharge end of the conveying component 100 to ensure that the conveying and picking mechanism 320 can clamp the cardboard on the discharge end of the conveying component 100.

[0050] Similarly, the material loading and picking mechanism 330 includes: a second vertical linear drive 331, which is transmission-connected to the longitudinal linear drive 310; a second material picking clamp 332, which is arranged at the lower end of the second vertical linear drive 331, and the second material picking clamp 332 can clamp the cardboard on the correcting component 200 to ensure that the material loading and picking mechanism 330 can clamp the cardboard on the correcting component 200.

[0051] It should be noted that, along the conveying direction of the conveying assembly 100, the conveying and fetching mechanism 320 is located in front of the loading and fetching mechanism 330 (based on the attached Figure 2 The first and second picking clamps 322 and 332 are lifted and lowered by corresponding linear drives to simultaneously pick up, move up and down the cardboard on the discharge end of the conveying component 100 and the cardboard on the correcting component 200, thereby realizing the synchronization of correcting feeding and loading and picking, thereby minimizing the waiting time for each other and avoiding affecting the efficiency. The entire mechanism occupies a small space, which can reduce the occupied space of the device.

[0052] It can be understood that the first vertical linear drive 321 and the second vertical linear drive 331 can be one of the devices such as a linear motor module, an electric push rod, a cylinder, and a linear drive mechanism driven by a rotary motor. For the first material picking fixture 322 and the second material picking fixture 332, it is only necessary to be able to clamp the cardboard. It can be a plurality of cylinder clamps or other clamps with opposite supports. In this embodiment, a plurality of suction cup arrays are used to facilitate the rapid and lossless placement of cardboard. The installation position of each linear drive and the corresponding component is determined by the specific structure of the corresponding linear drive. In this embodiment, the installation relationship between each linear drive and the corresponding component has been shown in the accompanying drawings and will not be described in detail.

[0053] In summary, the automatic loading device for cardboard products provided in this embodiment includes a conveying component 100, a rectifying component 200, and a material taking component 300. The conveying component 100 can stack multiple cardboard stacks 500 at intervals and longitudinally convey the cardboard stacks 500. The rectifying component 200 is arranged at the discharging end of the conveying path of the conveying component 100, and the rectifying component 200 can position the cardboard. The material taking component 300 is arranged at the discharging end of the conveying path of the conveying component 100, and the material taking component 300 can send the cardboard into the rectifying component 200, and send the cardboard positioned by the rectifying component 200 into the next process processing equipment.

[0054] During use, the conveying component 100 can receive the cardboard stacks 500 stacked manually and send the cardboard stacks 500 to the material taking station of the material taking component 300. That is, first, the conveying component 100 is turned off, and the materials are stacked and placed at the material placing station manually. After it is full, the conveying component 100 is started to send the materials to the material buffer station, and then the conveying component 100 is stopped and the materials are stacked and placed at the material placing station manually. This cycle continues until the material placing station, the material buffer station, and the material to be rectified station, so as to facilitate the material taking component 300 to send the cardboard from the material to be rectified station into the rectifying component 200.

[0055] Then, the material taking component 300 sends the cardboard from the material to be rectified station into the rectifying component 200. The rectifying component 200 rectifies and positions the cardboard, and then the material taking component 300 sends the cardboard positioned by the rectifying component 200 into the next process processing equipment. Thus, the rectified cardboard is automatically sent into the subsequent processing equipment (such as a dispensing machine), ensuring the consistency of the materials sent to the next process, avoiding the situation of misalignment due to manual feeding in the subsequent process, and thus reducing product scrapping.

[0056] Specifically: Through the action of the longitudinal linear driver 310, the first material taking fixture 322 is moved above the material to be rectified station, and at the same time, the second material taking fixture 332 is located above the rectifying bottom plate 210. Then, the first vertical linear driver 321 is respectively used to drive the first material taking fixture 322 to move downwards, and the second vertical linear driver 331 is used to drive the second material taking fixture 332 to move downwards, so as to clamp the cardboard at the material to be rectified station by the first material taking fixture 322 and clamp the cardboard on the rectifying bottom plate 210 by the second material taking fixture 332. At the same time, the first vertical linear driver 321 and the second vertical linear driver 331 are reset. Then, through the action of the longitudinal linear driver 310, the conveying and material taking mechanism 320 and the feeding and material taking mechanism 330 are driven to move, so that the first material taking fixture 322 moves above the rectifying bottom plate 210, and at the same time, the second material taking fixture 332 moves to the next process equipment.

[0057] Among them, the rectification and positioning work process is as follows: when the material reaches the rectification component 200 (placed on the rectification bottom plate 210), the positioning linear drivers 221 on the four sides extend simultaneously to automatically rectify and align the material.

[0058] In addition, the conveying component 100 can stack multiple cardboard stacks 500 at intervals and can longitudinally convey the cardboard stacks 500, and can cache multiple cardboard segments. Therefore, the loader can load two production lines or three production lines, or even more production lines at the same time, thereby improving the utilization efficiency of human resources.

[0059] It can be understood that the automatic loading device for cardboard products provided in this embodiment can be used not only for loading cardboard products, but also for loading products with other sheet structures or plate structures, such as display panels, engineering plastic plates, etc.

[0060] The specific embodiments described above have further elaborated on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
