Referring to fig. 3, the present embodiment discloses a packaging tool for logistics, which comprises a base 1, a cutter 3, a suction cup member 4 and a rotating device. 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. 4, 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 for respectively adsorbing and connecting the lower cutter 2 and the cutting piece 3.
Meanwhile, referring to fig. 5-7, the rotating device 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 pressing spring 13 is connected with a friction plate 14, the friction plate 14 is in pressing 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 pressing action of the plug screw 12 and can synchronously and integrally rotate under a set torsion. Furthermore, the rotating shaft 7 is provided with a fan-shaped sliding cavity 701 in the sleeve 6, and the circumferential direction of the sliding cavity 701 is consistent with the circumferential direction of the rotating shaft 7.
As shown in fig. 7, the rotating device further includes a positioning screw 8, the positioning screw 8 includes a threaded section 801 and a smooth pin shaft section 802, the pin shaft section 802 is a rectangular structure, after the threaded section 801 is screwed into the base 5 from a side surface, the pin shaft section 802 penetrates through a strip-shaped 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 on 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 contacted and connected.
Referring to fig. 5, one end of each of the two cantilever rods 10 is provided with a group of the suction cup component 4, the other end of each of the two cantilever rods 10 is 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 the side wall of the base 5 is further fixedly connected to a limiting rod 11. 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 part 4 connected with the cantilever rod 10 on the rotating shaft 7 can transfer the cutting part 3 to the position right above the inner cavity of the lower cutter 2 in the rotating and slipping process of the rotating shaft 7 in the sleeve 6 caused by further rotating the rotating shaft 7 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, and due to the blocking effect of the limiting rod 11 on the cantilever rod 10 on the sleeve 6, the sleeve 6 cannot rotate continuously, 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, 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 rotate any more, and at this time, the suction cup component 4 on the cantilever rod 10 connected to the rotating shaft 7 moves to above the lower cutter 2, that is, the cutting element 3 carried by the suction cup component 4 is brought to directly above the lower cutter 2, and similarly, the rotating shaft 7 moves downward again after the above-mentioned rising to the original height, or, when the cutting element 3 is heavy enough, the suction cup component 4 directly releases the cutting element 3, and the cutting element 3 moves downward. 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, because the pressing spring 13 always has an axial pressing force on the rotating shaft 7, the pressing spring 13 is twisted to a certain extent when the rotating shaft 7 rotates relative to the sleeve 6, and therefore, once the torque of the external part 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. 4, 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 blanked at one time, then the packaging skin 100 is taken out after blanking and attached on each shell, or the packaging skin 100 to be cut can be directly attached on the surfaces of the upper shell 300 and the lower shell 200 during blanking, 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.
Further, as a specific implementation detail, as shown in fig. 4, the bottom end surface of the cavity opening of the cutting member 3 is an inclined surface, and the cutting edge of the blade formed by the inclined surface is close to the outer wall side of the housing of the lower cutter 2, so as to better form a shearing mechanism for rapidly blanking the packaging skin 100.
As a more specific design choice, the suction cup part 4 comprises three suction cups, which are respectively located at three vertexes of the lower shell 200 of the V-shaped component, so that the lower shell 200 can be better grabbed and moved. Furthermore, the two adjacent suckers are connected and ventilated through steel pipes, so that the suckers are connected, rigid connection is realized, and the object can be conveniently grabbed. In addition, the cantilever bar 10 is connected to the upper end of the middle sucker, so that the stress of the structure is balanced, and the stability is improved.
Further, the strip-shaped notch 601 on the sleeve 6 is an arc-shaped through hole with a radian larger than pi, and an orifice of the arc-shaped through hole is opposite to an orifice of the sliding cavity 701 so as to reserve a larger space as far as possible to avoid the screw pin 8.
In addition, the end face of the rotating shaft 7 located at one end in the sleeve 6 of the present embodiment is embedded with a friction plate with a protruding end face, and the friction plate is in pressing contact with the friction plate 14, so as to improve the connection tightness between the rotating shaft 7 and the sleeve 6.
Finally, the packaging tool of the present embodiment is more complete and may be provided with a special wedging mechanism to receive the edge of the wrapper 100. Referring to fig. 8-10, includes a press, a clamp (not shown), a drive shaft 20, a long arm member and a short arm member. The clamping member is used for clamping at least one of the upper shell and the lower shell, and the clamping member can adopt the rotating device in the embodiment and an actuating mechanism of the sucker component 4. For example, after the lower housing 200 is placed 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 disposed at an interval to form two wedging seams that are separated from the inner and outer sides. The gripping member may also be a gripping element, such as a conventional 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. 9. The rigid link 21 is a rigid rod member that cannot be extended and contracted, and one end thereof is fixed 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 arranged 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 telescopic 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 storage and the protection of the edge part of the packaging skin 100 during packaging are realized.
In use, as shown in fig. 8, 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 contract, 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 while moving as shown in fig. 8, thereby automatically and quickly receiving redundant edge material 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 beautiful.
The method for accommodating the edge of the packaging skin 100 by the wedging mechanism is combined with the blanking process of the packaging skin 100 to form a set of complete packaging process of the packaging skin 100 with the V-shaped part, so that the whole packaging process is enriched.
When the edges of the packaging skin 100 are received, the surface of the V-shaped part can be perfectly covered with all the packaging skin 100 by further vacuum-pumping or thermal plasticizing or bonding according to the requirement. It should be noted that a series of the above-mentioned specific implementation structures and manners of the present invention mainly aim at cutting and edge receiving of the packaging skin 100 during packaging, and therefore, a more specific and complete covering or bonding technology for the 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.
