Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the functions of the invention clearer and easier to understand, the technical scheme of the invention is described in detail below. It should be understood by those skilled in the art that the following examples are illustrative of some specific implementations, configurations or modes for carrying out the invention, and are not limiting on the scope of the invention.
Referring to fig. 3, the present embodiment discloses a wedge-type packing mechanism for packing work, which includes a press, a holder (not shown), a driving shaft 20, a long arm member and a short arm member. The clamping member is used for clamping at least one of the upper and lower housings, for example, after the lower housing 200 is put in advance, the upper housing 300 is clamped right above the lower housing 200, so that the upper and lower housings of the V-shaped member are oppositely arranged at intervals, and two wedging seams which are separated from the inner side and the outer side are formed. The gripping member may be a conventional gripping element such as a robot.
The press machine of the embodiment is used for extruding and meshing the upper shell and the lower shell of the V-shaped part which are opposite and spaced in advance. Meanwhile, the present short arm member includes a rigid link 21 and an inner wedge wheel 25, and the inner wedge wheel 25 is constructed as shown in fig. 4. The rigid link 21 is a rigid rod member which cannot be extended and retracted, and one end thereof is fixedly connected to the drive shaft 20. The rim of the inner wedging wheel 25 is in a cutting edge shape, and the inner wedging wheel 25 can be installed at the free end of the rigid connecting rod 21 in a rotating way.
Meanwhile, the long arm member includes an elastic expansion link 24 and an external wedging wheel 25, and the elastic expansion link 24 is a rod member capable of being axially elongated under a tensile force, and one end thereof is fixedly connected to the driving shaft 20. The rim of the outer wedging wheel 25 is in a cutting edge shape, and the outer wedging wheel 25 can be installed at the free end of the elastic telescopic rod 24 in a rotating way. When the packaging machine is used, the rim of the inner wedging wheel 25 can be wedged into the inner wedging seam of the V-shaped piece, the rim of the outer wedging wheel 25 can be wedged into the outer wedging seam of the V-shaped piece, the elastic expansion rod 24 is always kept in an elastic stretching state at the moment, front and rear clamping forces are formed from two sides of the V-shaped piece, so that when the driving shaft 20 rotates, the edges of the upper and lower packaging skins 100 which are covered on the V-shaped piece in advance are wedged into the inner and outer wedging seams of the V-shaped piece, and the edge part of the packaging skin 100 is stored and protected during packaging.
In use, as shown in fig. 3, the two wedging wheels 25 are first wedged from the tip of one side of the V-shaped member, which is exactly matched with the initial interval of the two wedging wheels 25, and then the two wedging wheels 25 are respectively moved along the inner side and the outer side of the wedging seam of the V-shaped member, and if necessary, the wedging wheels 25 can also be made into wheels directly driven by a micro motor to rotate. Because the rigid connecting rod 21 has a constant length, the elastic telescopic rod 24 can adaptively extend and shorten, so that a pair of clamping wheels formed by the two wedging wheels 25 can stably move at the wedging seam, and wedge the edge of the packaging skin 100 into the wedging seam as shown in fig. 5 while moving, thereby automatically and quickly accommodating redundant edge materials of the packaging skin 100, protecting the edge, preventing the edge from being exposed outside and accidentally pulled and scattered, further fixing the edge of the packaging skin 100 on a V-shaped piece, and being more attractive.
As an implementation detail, the rigid link 21 and the elastic telescopic rod 24 are both disposed to extend outward along the radial direction of the driving shaft 20. The elastic expansion link 24 is located right above the rigid link 21, and the connecting line between the inner wedging wheel 25 and the outer wedging wheel 25 is located in the length direction of the rigid link 21, so as to better wedge the edges of the packing skin 100 on the inner and outer sides of the V-shaped part.
Further, a mandrel is fixedly connected to the lower side of the free end of the elastic telescopic rod 24, the mandrel is perpendicular to the elastic telescopic rod 24, and the outer wedging wheels 25 are rotatably mounted on the mandrel near the bottom end of the mandrel, so that the two wedging wheels 25 can be accurately located in the wedging gap as much as possible, or the two wedging wheels can be opposite to each other.
More specifically, in order to realize the self-adaptive expansion and contraction of the elastic expansion and contraction rod 24, the elastic expansion and contraction rod 24 comprises a cylindrical rod 22 and a circular sleeve 23, one end of the cylindrical rod 22 is fixedly connected to the driving shaft 20, the other end of the cylindrical rod 22 is inserted into the sleeve 23 in a sliding fit manner and is connected with a tension bearing spring in the sleeve 23, the end of the tension bearing spring is connected into the sleeve 23, and the free end of the sleeve 23 is provided with the outer wedging wheel 25.
Further, a limiting column 28 is arranged on the cylindrical rod 22, the limiting column 28 can be in contact with the end face of the sleeve 23 to limit the relative sliding displacement between the cylindrical rod 22 and the sleeve 23, when the sleeve 23 slides along the cylindrical rod 22 to be in contact with the limiting column 28, the inner wedging wheel 25 is circumscribed with the outer wedging wheel 25, namely, at the beginning of use, the two wedging wheels 25 can be opposite and tangent to each other so as to better adapt to the tip parts on the two sides of the V-shaped part, so that at the initial moment, the gap between the two wedging wheels 25 is matched with the tip parts, the directional movement of the two wedging wheels 25 can be smoothly realized, the relatively small distance trend can be kept between the two wedging wheels 25 all the time, and therefore, in the wedging process, the wedging force on the edge of the packaging skin 100 is improved. Of course, in order to achieve the above effect, the present embodiment may also be designed as follows: a limiting convex part 26 is fixedly connected to the sleeve 23, a 7-shaped stop lever 27 is connected to the rigid connecting rod 21, and when the limiting convex part 26 is contacted with the stop lever, the inner wedging wheel 25 is externally tangent to the outer wedging wheel 25; the structure is simpler and easy to manufacture.
Finally, for the gripper mentioned at the beginning of the present embodiment, a preferred embodiment is also given here, and for the wedge packaging mechanism, an actuator for blanking the wrapper 100 during packaging is also designed:
referring to fig. 6, the present embodiment discloses a packaging tool, which comprises a base 1, a cutting member 3, a suction member 4 and a rotating device, wherein the rotating device can be referred to as the aforementioned clamping member. Specifically, the upper surface of the base 1 is convexly provided with a shell-shaped lower cutter 2, the shape of the inner cavity of the lower cutter 2 is matched with that of the lower shell 200 of the V-shaped cavity, that is, the lower cutter 2 is also provided with a closed wall-type side wall with the same shape as that of the lower shell 200, so that the lower shell 200 can be flatly placed in the inner cavity of the lower cutter 2. As shown in fig. 7, the cross section of the cavity wall of the lower cutter 2 is in a right triangle shape, and one of the right-angled sides is perpendicular to the upper surface of the base 1, so that the right-angled surface where the right-angled side is located forms one of the shearing surfaces. Meanwhile, a cavity with a shape matched with that of the lower cutter 2 is convexly arranged on the lower surface of the cutting piece 3, and when the cutting piece 3 moves above the lower cutter 2, the cavity opening of the cavity is arranged opposite to the lower cutter 2 so as to be matched with the lower cutter, namely: the inner side wall of the cavity of the cutting member 3 (as the other shearing surface) is in sliding fit with the outer side wall of the housing of the lower cutter 2 (one of the shearing surfaces) so that the cutting member 3 just covers the whole lower cutter 2 when moving downwards, and the covering process is a shearing process. Preferably, at the time of production, a more important recommended structure: the height of the lower cutter 2 protruding out of the upper surface of the base 1 is preferably lower than the height of the top end surface of the lower shell 200 arranged in the inner cavity of the lower cutter 2, namely, the top end surface of the lower shell 200 is exposed out of the cavity opening of the inner cavity of the lower cutter 2 after the lower shell 200 is arranged in the cavity of the lower cutter 2; on this basis, and also needs: the inclination of the inclined plane of the hypotenuse of the right triangle cross section of the cavity wall of the lower cutter 2, i.e. the inclination of the inclined plane of the cutting edge of the top end face of the lower cutter 2, and the thickness of the cavity wall of the lower cutter 2, is such that the punched edge of the packaging wrapper 100 pressed by the lower housing 200 can be curled upwards and extended above the top end face of the lower housing 200, i.e. the curled edge upwards is located at the wedging seam, so that the punched packaging wrapper 100 can be wedged thoroughly and rapidly into the wedging seam of the V-shaped member.
In addition, the sucking disc parts 4 are provided with two groups respectively for adsorbing and connecting the lower cutter 2 and the cutting piece 3.
Meanwhile, referring to fig. 8-10, the rotating device (combining with the suction cup component 4, i.e. the function of the clamping member) of the present embodiment includes a base 5, a sleeve 6, a rotating shaft 7, and two cantilever rods 10, wherein the sleeve 6 is rotatably installed in the base 5. The rotating shaft 7 is a stepped shaft, and specifically can be a first-stage stepped shaft formed by two shaft sections with different sizes. In order to match with the rotating shaft 7, one end opening of the sleeve 6 is provided with a spigot, so that a positioning effect is formed. The other end of the sleeve 6 is internally threaded with a plug 12, the large end of the stepped shaft is rotatably mounted in the sleeve 6, i.e. can freely rotate in the sleeve 6, and a compression spring 13 is connected to the end face of the plug 12 screwed into the sleeve 6. The end of the pressure spring 13 is connected with a friction plate 14, the friction plate 14 is in compression contact with the large end face of the stepped shaft, and the rotating shaft 7 and the sleeve 6 are connected into a whole under the compression action of the screw plug 12 so as to synchronously and integrally rotate under a set torsion. Furthermore, the rotating shaft 7 has a sector-shaped sliding cavity 701 located inside the sleeve 6, and the circumferential direction of the sliding cavity 701 coincides with the circumferential direction of the rotating shaft 7.
As shown in fig. 10, the rotating device further includes a positioning screw 8, the positioning screw 8 includes a thread section 801 and a smooth pin shaft section 802, the pin shaft section 802 is a rectangular structure, after the thread section 801 is screwed into the base 5 from a side surface, the pin shaft section 802 penetrates through a strip notch 601 on the wall of the sleeve 6 and extends into the sliding cavity 701, and an arc-shaped return spring 9 is installed in the sliding cavity 701, one end of the return spring 9 is connected in a blind hole in the side wall of the sliding cavity 701, and the other end of the return spring is connected to the side wall of the pin shaft section 802, which is why the pin shaft section 802 is a rectangular structure, and is convenient for stable attachment when the end surface of the return spring 9 is in contact connection.
Referring to fig. 8, a set of the suction cup component 4 is respectively installed at one end of each of the two cantilever rods 10, the other ends of the two cantilever rods 10 are respectively and fixedly connected to the cylindrical surfaces of the sleeve 6 and the rotating shaft 7 extending out of the end surface of the base 5, and a limit rod 11 is further and fixedly connected to the side wall of the base 5. When the sleeve 6 and the rotating shaft 7 rotate integrally until the sleeve 6 is contacted with the limiting rod 11 and can not rotate continuously, the sucker component 4 connected with the cantilever rod 10 on the sleeve 6 transfers the lower shell 200 to the position right above the inner cavity of the lower cutter 2. When the pin shaft section 802 contacts with the hole of the blind hole, the suction cup component 4 connected with the cantilever rod 10 on the rotating shaft 7 can transfer the cutting piece 3 to the position right above the inner cavity of the lower cutting knife 2 in the process that the rotating shaft 7 rotates and slips in the sleeve 6 due to the fact that the rotating shaft 7 further rotates after the sleeve 6 contacts with the limiting rod 11.
Based on the above packaging tools, the present embodiment provides a blanking process of the packaging skin 100, specifically: firstly, the rotating shaft 7 is driven to rotate by external power, the rotating shaft 7 and the sleeve 6 are connected into a whole because the pressing spring 13 is pressed by the screw plug 12, therefore, when the rotating shaft 7 starts to rotate, the rotating shaft 7 and the sleeve 6 form an integrated structure which can synchronously rotate together, when the cantilever rod 10 connected on the sleeve 6 is contacted with the limiting rod 11, the sucker component 4 moves right above the lower cutter 2, namely the lower shell 200 of the V-shaped piece carried by the sucker component 4 is positioned above the lower cutter 2, at this time, the rotating shaft 7 moves downwards or the sucker releases the lower shell 200, and then the lower shell 200 falls into the inner cavity of the lower cutter 2, and the flat placement is completed. When the rotating shaft 7 moves downwards, a main shaft of a driving part such as a motor can be connected to the rotating shaft 7, then the driving part such as the motor is installed on a vertically arranged hydraulic rod, after the lower shell 200 moves in place, the hydraulic rod contracts, the lower shell 200 moves downwards into the cavity of the lower cutter 2, the flat arrangement is realized, and after the arrangement is finished, the hydraulic rod rises to the original height.
Then, the external driving component continues to apply torque to the rotating shaft 7, because the stopping action of the limiting rod 11 on the cantilever rod 10 on the sleeve 6 at this time, the sleeve 6 cannot continue to rotate, and at this time, the input torque overcomes the axial pressing force of the pressing spring 13 between the sleeve 6 and the rotating shaft 7, so that the friction plate 14 and the end surface of the rotating shaft 7 slip, so that the rotating shaft 7 slips in the sleeve 6, that is, at this time, the rotating shaft 7 continues to rotate while the sleeve 6 remains stationary, when the rotating shaft 7 rotates until the screw pin 8 contacts with the side wall of the sliding cavity 701 in the arc direction, the rotating shaft 7 cannot continue to rotate, at this time, the suction cup component 4 on the cantilever rod 10 connected to the rotating shaft 7 moves to the upper side of the lower cutter 2, that is, the cutting piece 3 carried by the suction cup component 4 is brought to the right above the lower cutter 2, and in the same way, the rotating shaft 7 which ascends to the original height returns to move downwards again, or, when the cutting piece 3 is heavy enough, the suction cup component 4 directly releases the cutting piece 3 to move downwards. After the torque of the rotating shaft 7 is removed, under the action of the strong torsional reset force of the reset spring 9 and the assistance of the torsional reset force of the pressing spring 13, the inner shaft is reset in time and automatically rotates to the initial relative position between the inner shaft and the outer pipe. For the torsional restoring force, the pressing spring 13 always has an axial pressing force on the rotating shaft 7, so that the pressing spring 13 is twisted to a certain extent when the rotating shaft 7 rotates relative to the sleeve 6, and once the external torque on the rotating shaft 7 is released, the pressing spring 13 is also twisted and reset, so that the torsional restoring force is generated; therefore, in practice, it is preferable that the above-mentioned compression spring 13 is replaced by a compression torsion spring which has not only axial elasticity to realize the integral connection of the rotating shaft 7 and the sleeve 6 but also strong torsion restoring force like a torsion spring. As shown in fig. 7, when the cutting member 3 moves downward, the cutting member 3 moves downward to the lower cutter 2, the lower cutter 2 is covered, and a cutting motion is realized in the covering process, so that the packaging skin 100 is blanked and cut, and then is blanked, one or more packaging skins 100 with a desired size are obtained, and the excess parts (edge parts) of the packaging skin 100 are subsequently wedged into the V-shaped members, thereby realizing the storage and packaging of the excess parts of the packaging skin 100. For the subsequent covering and attaching of the cut packaging skin 100 on the corresponding shell, a plurality of materials of the packaging skin 100 can be punched at one time, then the packaging skin 100 is taken out after punching and attached on each shell, or the cut packaging skin 100 can be directly attached on the surfaces of the upper shell 300 and the lower shell 200 during punching, because of the symmetrical structure of the upper shell and the lower shell, the upper shell 300 can be also put into the inner cavity of the lower cutter 2; after the upper and lower shells are covered with the upper packaging skin 100, the spacing opposite positioning of the upper and lower shells is executed, and then the process of wedging the edge of the packaging skin 100 is carried out. The above is only an example to summarize, and as to how to perform a more continuous and efficient packaging process, the embodiment should be adaptively selected according to the requirement of production efficiency and the material of the packaging skin 100 itself, which is not always illustrated in this embodiment.
Finally, the packaging skin 100 is accommodated according to the method for accommodating the edge of the packaging skin 100 by the wedging type packaging mechanism, so that a set of complete packaging process of the packaging skin 100 with V-shaped parts is obtained, the automation degree is high, and the efficiency is good.
After the edges of the packaging skin 100 are received in the interior of the V-shaped component, further vacuuming or thermal plasticizing or bonding can be selected as required to perfectly cover the surface of the V-shaped component with all the packaging skin 100. Finally, it should be noted that the foregoing series of embodiments mainly relate to cutting and edge receiving of the packaging skin 100 during packaging, and therefore, the covering or bonding technology for a more specific and complete packaging skin 100 is not described in detail, but those skilled in the art should know related art means.
It should be noted that, in the present invention, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Therefore, it should be understood by those skilled in the art that any modification and equivalent replacement of the embodiments disclosed herein without departing from the technical spirit of the present invention shall be included in the scope of the present invention.
