Description

[0002] As we all know, products need to be packaged after they are made, such as dental floss that needs to be quantitatively packed into packaging bags before leaving the factory. As for product packaging (such as bagging), the following methods are generally used in the market:

[0003] ① Manual packaging is used, but manual operation not only has low production efficiency and low precision, but also has high labor intensity and high production cost, which is not conducive to production development.

[0004] ② Use a vibrating plate or conveying rod device to deliver the product into the packaging bag. Although this operation method has a high degree of automation, it will cause the product to be scattered in the packaging bag, which not only affects the appearance but also easily causes the packaging bag to be damaged.

DETAILED DESCRIPTION

[0040] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0041] Embodiment 1:

[0042] Please see attached Figure 1 To Attachment Fig.10As shown, this embodiment 1 provides a material loading and unloading device, which includes a loading device 1, a transfer device 2 and a material return mechanism 3, wherein the loading device 1 is provided with a carrier 10 and a pushing mechanism 11, the carrier 10 is provided with a plurality of carrier components P arranged at intervals and used to receive materials, the pushing mechanism 11 is provided with a push rod 110 that can be moved to the bottom of the carrier 10, and the push rod 110 can move upward to push the material to move upward to separate from the carrier component P; the transfer device 2 is provided with a material picking unit composed of a plurality of material picking rods 20, an adjustment mechanism that can adjust the relative position relationship between the plurality of material picking rods 20, and a mechanism that can drive the material picking unit and the adjustment mechanism to move ... The main driving device moves together with the mechanism. When the main driving device drives the material picking unit to move above the carrier 10, the adjusting mechanism can drive the multiple material picking rods 20 to correspond to the multiple material carrying components P one by one, so as to receive the materials pushed upward by the pushing mechanism 11; and when the main driving device drives the material picking unit to move to the unloading station, the adjusting mechanism can drive the multiple material picking rods 20 to rotate relative to each other and / or move horizontally, so that the materials on the multiple material picking rods 20 are close to each other; the material returning mechanism 3 is arranged at the unloading station, and can cooperate with the multiple material picking rods 20 to return the materials from the material picking rods 20.

[0043] From the above, it can be seen that the working mode of the material loading and unloading device described in this application is:

[0044] S1. The main drive device first drives the material picking unit to move above the carrier 10 according to the control instruction, and then the adjustment mechanism drives the plurality of material picking rods 20 to rotate relative to each other and / or move horizontally according to the control instruction, so that the plurality of material picking rods 20 correspond to the plurality of material carrying components P one by one; then the main drive device drives the plurality of material picking rods 20 to descend synchronously, so that the plurality of material picking rods 20 abut against the plurality of material carrying components P, so that the material moves from the material carrying component P to the material picking rod 20. It can be understood that based on the configuration of the material picking rod 20, the material loading and unloading device of the present application is particularly suitable for processing "materials with annular portions".

[0045] S2. The push rod 110 moves to the bottom of the material loading assembly P which is in contact with the material picking rod 20, and then the push rod 110 moves upward to push the material (generally a stack of materials) arranged on the material loading assembly P upward to the material picking rod 20, thereby completing the material picking work of the material picking rod 20.

[0046] It is understandable that after the material picking work of the material picking rod 20 is completed, the push rod 110 will descend and reset to wait for the next work instruction.

[0047] S3. First, the main driving device drives the material picking unit that has completed the material picking work to move to the material unloading station according to the control instruction, wherein the specific work content of the material unloading station can be determined according to the actual production application of the material unloading and unloading device described in this application. This application does not make any limiting requirements, and only exemplifies that the material unloading station can be designed as a bagging station, that is, a bag-holding device capable of receiving a packaging bag and holding the bag mouth open is provided at the material unloading station;

[0048] Then, the adjustment mechanism drives the plurality of the picking rods 20 to rotate and / or move horizontally relative to each other according to the control instructions, so that the materials on the plurality of the picking rods 20 are brought closer to each other to meet the needs of subsequent processing; for example: based on the above-mentioned bagging station, the adjustment mechanism controls the picking rods 20 to rotate and / or move horizontally, so that the materials on the plurality of the picking rods 20 are brought closer to each other, and the materials are surrounded to form a shape that is similar to the opening shape of the bag opening but smaller than the opening area of ​​the bag opening, so as to facilitate the materials to fall into the packaging bag smoothly and regularly;

[0049] Subsequently, the material return mechanism 3 cooperates with the plurality of material picking rods 20 to withdraw / detach the material from the material picking rods 20, and the material falls into the packaging bag smoothly and regularly.

[0050] In order to better understand the structure and working principle of the material loading and unloading device described in the present application, the specific structure of the material loading and unloading device described in the present application is described in detail below.

[0051] First, regarding the loading device 1 .

[0052] Since the material loading and unloading device described in this application is particularly suitable for processing "materials with annular portions", the preferred implementation structure of the carrier 10 described in this embodiment 1 is: Figure 3 To Attachment Figure 5As shown, the carrier 10 is provided with a carrier 102 and a plurality of carrier components P for receiving materials and arranged in rows on the carrier 102. Each carrier component P is provided with a main connecting rod 100 for the annular portion of the material to be sleeved and an auxiliary rod 101 arranged beside the main connecting rod 100 and used to resist and limit at least two different positions of the material. For example, when the material is dental floss, the annular head F1 of the dental floss can be sleeved on the main connecting rod 100, and then the handle F2 of the dental floss can be inserted between the two auxiliary rods 101, that is, the two auxiliary rods 101 are used to resist and limit the opposite sides of the handle F2 of the dental floss. It can be understood that the structure of the carrier 10 described in this embodiment 1 is simple and reasonable. On the one hand, it is easy to place materials in piles and the restriction of the material pile is stable. On the other hand, it is easy to process and manufacture, and the manufacturing cost is low.

[0053] Furthermore, based on the functions of the main connecting rod 100 and the auxiliary rod 101, it can be known that the main connecting rod 100 is a contoured structure adapted to the shape of the annular portion of the material, and thus the specific shape of the main connecting rod 100 is not unique, and the present application does not impose any restriction requirements, and the specific shape is determined according to the shape of the material; the auxiliary rod 101 can adopt a pin structure, which has a simple structure and is easy to assemble; and the number and layout of the auxiliary rods 101 are determined based on the shape of the material, and the present application does not impose any restriction requirements.

[0054] Furthermore, in order to cooperate with the push rod 110, the present embodiment 1 also has a plurality of through holes 103 (see attached) on the bottom wall of the carrier 102 for the push rod 110 to movably pass through. Figure 4 As shown), it can be understood that the plurality of through holes 103 correspond to the plurality of material carrying components P one by one.

[0055] Furthermore, in order to meet the needs of automated production, the feeding device 1 of this embodiment 1 is also provided with a horizontal driving mechanism B12, which can be seen in the attached Figure 2 As shown, the horizontal drive mechanism B12 can drive the carrier 10 to move along the first horizontal direction (the definition of which is described below), so that the carrier 10 can be transferred between different workstations, which satisfies the needs of automated processing. As for the specific implementation structure of the horizontal drive mechanism B12, a linear drive module can be preferably used, such as a linear motor, or a "motor and lead screw module combination" structure, which belongs to the conventional technical means in the field of mechanical automation, so it will not be described in detail here.

[0056] In addition, in order to improve the pushing efficiency and quality of the pushing mechanism 11, the present embodiment 1 preferably designs the number of the pushing rods 110 to be the same as the number of the material picking rods 20. It is understandable that the pushing rods 110 are also configured in plurality; and according to the processing requirements and the layout of the through holes 103 (in rows and columns), the present embodiment 1 also optimizes the arrangement of the plurality of pushing rods 110 side by side along the first horizontal direction.

[0057] In addition, in order to enable the push rod 110 to move to the bottom of the carrier 10 and move upward, the present embodiment 1 also makes the following structural design: Figure 2 As shown, the pushing mechanism 11 is also provided with a lifting drive mechanism 111 capable of driving the plurality of push rods 110 to perform lifting movements together, and a horizontal drive mechanism A112 capable of driving the lifting drive mechanism 111 to move in a second horizontal direction perpendicular to the first horizontal direction. The horizontal drive mechanism A112 can cooperate with the lifting drive mechanism 111 to adjust the positional relationship of the plurality of push rods 110 relative to the plurality of through holes 103.

[0058] Furthermore, the lifting drive mechanism 111 and the horizontal drive mechanism A112 can preferably adopt a linear drive module, such as a linear motor, or a "motor and lead screw module combination" structure. In addition, it is understandable that a mounting seat 113 is fixedly provided on the power output end of the lifting drive mechanism 111 for vertical and fixed installation of multiple push rods 110.

[0059] Next, let us discuss the transfer device 2 .

[0060] According to the processing requirements, in this embodiment 1, the main drive device preferably adopts a multi-axis manipulator (not shown in the figure), the adjustment mechanism is locked and connected to the execution end of the main drive device through a quick-change structure, and the multiple material-picking rods 20 are respectively installed on the adjustment mechanism. Moreover, under the coordinated action of the main drive device and the adjustment mechanism, when the material-picking unit is located above the carrier 10, the multiple material-picking rods 20 in the material-picking unit are arranged vertically and abut against the multiple main connecting rods 100 one by one at the same time; when the material-picking unit is located above the unloading station, the multiple material-picking rods 20 are also arranged vertically.

[0061] Furthermore, in this embodiment 1, the picking rod 20 is configured as three, and for ease of description, the three picking rods 20 are defined as the first picking rod 20a, the second picking rod 20b and the third picking rod 20c. The adjustment mechanism includes a mounting plate A21, and a rotary drive member and a linear drive member respectively disposed on the mounting plate A21, wherein the mounting plate A21 is locked and connected to the execution end of the main drive device through a quick-change structure such as a quick-change disk, the rotary drive member can drive the first picking rod 20a to rotate, and the linear drive member can drive the second picking rod 20b to move closer to or away from the third picking rod 20c, as shown in the attached figure. Figure 6 and attached Figure 7 That is, the relative position relationship between the three material picking rods 20 can be adjusted through the rotary drive member and the linear drive member, thereby meeting the material picking and returning processing requirements of the material picking rod 20.

[0062] For further information, please refer to the attached Figure 6 and attached Figure 7 As shown, the rotating drive component includes a rotating motor 22 fixedly arranged on the mounting plate A21, and the power output end of the rotating motor 22 is transmission-connected to the first material picking rod 20a through a coupling (specifically, one end of the rod body 200 of the first material picking rod 20a is transmission-connected to the power output end of the rotating motor 22 through a coupling). The linear drive component includes a slide rail 23 fixedly laid on the mounting plate A21, a mounting plate B24 slidably connected to the slide rail 23, and a driving cylinder 25 respectively connected to the mounting plate A21 and the mounting plate B24. The second material picking rod 20b is fixedly connected to the mounting plate B24 (specifically, one end of the rod body 200 of the second material picking rod 20b is fixedly connected to the mounting plate B24), and the third material picking rod 20c is fixedly connected to the mounting plate A21 and close to one end of the slide rail 23 (specifically, one end of the rod body 200 of the third material picking rod 20c is fixedly connected to the mounting plate A21).

[0063] Supplementary explanation: “The driving cylinder 25 is connected to the mounting plate A21 and the mounting plate B24 respectively” can be understood as: the cylinder body of the driving cylinder 25 is fixedly connected to the mounting plate A21, and the piston rod of the driving cylinder 25 is fixedly connected to the mounting plate B24. Figure 7 shown.

[0064] In addition, regarding the material taking rod 20, its preferred implementation structure is: Figure 8 and attached Fig. 9As shown, each of the material picking rods 20 is provided with a rod body 200, a receiving cavity 201 formed inside the rod body 200, and a cylinder 202 and a tongue 203 respectively arranged in the receiving cavity 201. The tongue 203 can be completely retracted into the receiving cavity 201 under the drive of the cylinder 202 to enable the material to be sleeved on the rod body 200 or detached from the rod body 200; or, the tongue 203 can also be partially extended out of the rod body 200 under the drive of the cylinder 202 to stop the material sleeved on the rod body 200. It can be understood that, ① when the material picking rod 20 is picking up materials, the cylinder 202 is used to drive the tongue 203 to retract into the receiving chamber 201, so that the material can move from bottom to top and be sleeved on the rod body 200; after the material transfer is completed, the cylinder 202 is used to drive the tongue 203 to partially extend out of the rod body 200, so as to stop the material sleeved on the rod body 200 and prevent the material from falling off. ② When the material picking rod 20 is returning materials, the cylinder 202 is used to drive the tongue 203 to retract into the receiving chamber 201, release the stop on the material, and enable the material to be separated from the rod body 200.

[0065] Furthermore, the specific structure of the embodiment 1 for realizing the cylinder 202 driving the tongue 203 to perform telescopic movement is as follows: Figure 8 and attached Fig. 9As shown, taking the vertical state of the material-taking rod 20 as a reference, the receiving cavity 201 is integrally formed at the lower inner part of the rod body 200, and the receiving cavity 201 can be divided into three sections from top to bottom, namely, an upper section 2010, a middle section 2011 and a lower section 2012 which are interconnected; wherein, the cylinder 202 is positioned in the upper section 2010, and a connecting block 205 which can slide vertically is provided in the middle section 2011. It can be understood that a guide surface extending vertically is formed on the inner wall of the middle section 2011. One end of the connecting block 205 is positioned and connected to the piston rod of the cylinder 202, and the other end of the connecting block 205 is formed into a bifurcated structure; the lower section 2012 is opened at the opposite sides of the bottom of the rod body 200 to form two inlets and outlets 2013, and the inner wall of the lower section 2012 and the positions close to the two inlets and outlets 2010 are also formed with limiting and guiding inclined surfaces 2014. It can be understood that the two limiting and guiding inclined surfaces 2014 are respectively connected to the inner wall of the middle section 2011. In addition, the lower section 2012 contains two blocking tongues 203, one end of each of the two blocking tongues 203 is inserted into the bifurcated structure and is rotatably connected to the bifurcated structure through a pin shaft, and the other ends of the two blocking tongues 203 correspond to the two inlets and outlets 2013 respectively; that is, when the piston rod of the cylinder 202 retracts upward, the connecting block 205 moves upward and correspondingly drives one end of the two blocking tongues 203 to move upward, and then the two limiting and guiding inclined surfaces 2014 are closed. Under the action of the two blocking tongues 203, the two blocking tongues 203 are relatively deflected so that the other ends of the two blocking tongues 203 can be retracted into the lower section 2012; and when the piston rod of the cylinder 202 is extended downward, the connecting block 205 moves downward and correspondingly drives one end of the two blocking tongues 203 to move downward. Similarly, under the action of the two limiting and guiding inclined surfaces 2014, the two blocking tongues 203 are deflected in opposite directions so that the other ends of the two blocking tongues 203 can be extended out of the two inlets and outlets 2010.

[0066] Next, let's talk about the material return mechanism 3.

[0067] In this embodiment 1, the structure of the material-removing mechanism 3 and the plurality of material-removing rods 20 cooperating to remove the material from the material-removing rods 20 is as follows: Figure 6 , Attachment Figure 8 and attached Fig.10As shown, each of the material picking rods 20 is also provided with a material stripping block 204 sleeved on the outside of the rod body 200 through a linear bearing, and the material stripping mechanism 3 is provided with a stopper 30 and a material stripping cylinder 31 capable of driving the stopper 30 to move toward the material picking unit to stop the material stripping blocks 204 on the plurality of material picking rods 20. It can be understood that when the material picking rod 20 is picking up materials, the material stripping block 204 will move upward by the force of the material moving upward, and when the material picking rod 20 is stripping materials, the material stripping cylinder 31 drives the stopper 30 to move toward the material picking unit, so that the stopper 30 stops the material stripping blocks 204 on the plurality of material picking rods 20, and then the plurality of rod bodies 200 move upward synchronously, and the materials sleeved on the rod bodies 200 can be separated from the rod bodies 200 under the pressure of the material stripping block 204.

[0068] For further information, please see the attached Figure 6 As shown, each of the stripping blocks 204 is formed with a protrusion A2040; Fig.10 As shown, according to the layout of the plurality of material stripping blocks 204, the end of the stopper 30 facing the material taking unit is provided with a plurality of protrusions B300, and the plurality of protrusions B300 can correspondingly abut against and stop the plurality of protrusions A2040. It can be understood that the end of the stopper 30 facing the material taking unit is a contoured structure, which not only satisfies the synchronous stopping function of the plurality of material stripping blocks 204, but also satisfies the avoidance of other parts (such as the rod body 200) on the plurality of material taking rods 20. In short, by means of the stopper 30, the processing cost can be well saved, the occupied space can be saved, and the production implementation is facilitated.

[0069] Finally, the prefixes "first", "second", "third", etc. of the component names in the patent specification of the present invention (such as the first material picking rod, the second material picking rod, the third material picking rod, etc.), and the suffixes "A", "B", etc. of the component names (such as horizontal drive mechanism A, horizontal drive mechanism B, etc.) are only for the convenience of description and are not used to limit the scope of the implementation of the patent of this invention.

[0070] To sum up, the material loading and unloading device of the present invention integrates multiple functions such as "automatic material loading", "quantitative material picking", "material enclosure shape adjustment", and "automatic material unloading / returning". It not only has a high degree of automation and integration, greatly improving production efficiency and processing accuracy, but also can ensure that the material enclosure shape can well meet the processing requirements of the subsequent process, such as ensuring that the material falls into the packaging bag regularly and compactly to avoid being scattered.

[0071] Many specific details are described in the above description to facilitate a full understanding of the present invention.
