Example 1:

fig. 1 is a schematic structural diagram of a middle screw mechanism 1 according to the present invention. The utility model discloses a screw mechanism 1 generally be cylindrical, and figure 1 is the axial view of screw mechanism 1. The screw mechanism 1 comprises a screw thread and a shaft part 102, the end of the screw thread in axial view being shown as a screw end part 101, the screw end part 101 also rotating around the shaft part 102 when the screw mechanism 1 is rotated around its own shaft part 102. In some embodiments there are a plurality of screw mechanisms 1, in this application it is mentioned that the screw mechanisms 1 are arranged with the same initial angle, i.e. that the threaded end 101 of each screw mechanism 1 is in the same position.

Fig. 2-4 are schematic structural diagrams of an embodiment of the present invention, wherein fig. 2 is a general schematic diagram, fig. 3 is a front view, and fig. 4 is a top view. In the present embodiment, a frame 2 is included. The bottom of frame 2 includes first backup pad 4, is provided with four stands 3 on the first backup pad 4. The stand 3 sets up perpendicular to first backup pad 4, the one end and the 4 fixed connection of first backup pad of stand 3, the other end and second backup pad 13 fixed connection, and each stand 3 is the same with the hookup location of first backup pad 4, second backup pad 13 for first backup pad 4, second backup pad 13 parallel arrangement. The first support plate 4, the second support plate 13 and the upright 3 constitute the main structure of the frame 2. In other embodiments, the number of the columns 3 is not fixed, and only the requirement of arranging the first support plate 4 and the second support plate 13 in parallel is satisfied.

The second support plate 13 is not a complete plane but has an opening through which the supply cartridge passes. The overall shape of the second support plate 13 is thus "square". In the present embodiment, the cartridges in the stacked state pass through the opening of the second support plate 13 from top to bottom and are separated. In other embodiments, the stacked cartridges may pass through the opening from bottom to top to achieve a similar separation effect.

The first support plate 4 is provided with a transmission mechanism 6. After the magazine has reached the disengaged state, it is transported out of the device by means of the transport mechanism 6. In the present embodiment, the transfer mechanism 6 is preferably a roller conveyor. In other embodiments, the transfer mechanism 6 may be other types of transfer mechanisms as long as the technical effect of transferring the separated cartridges out of the device is achieved.

A plurality of screw mechanisms 1 are further disposed between the first support plate 4 and the second support plate 13, in this embodiment, the screw mechanisms 1 are preferably screws, and the screw mechanisms 1 are disposed in parallel with the columns 3 and are respectively connected to the first support plate 4 and the second support plate 13. In particular, one end of the screw mechanism 1 is connected to the second support plate 13 through the bearing seat 9, so that the screw mechanism 1 and the second support plate 13 can rotate around the shaft 102 (shown in fig. 1) of the screw mechanism while maintaining the same position. The rib of the magazine is in contact with the thread of the screw mechanism 1, in particular only one rib of the magazine is accommodated between every two threads. As the screw mechanism 1 is rotated, its screw thread moves downward. Under the action of the screw thread, the rib edge of the material box is also forced to move downwards. In other embodiments, the screw mechanism 1 may also be in other forms of threaded structures, and the arrangement direction thereof is not necessarily vertical, as long as the screw thread can drive the material box rib to move along with the rotation of the screw mechanism 1, the same technical effect can be obtained.

A drive assembly 5 is also included in this embodiment. The driving assembly 5 comprises a motor 10, a synchronous pulley 11 and a synchronous belt 12. In other embodiments, the motor 10 may be a drive machine driven by other forms of energy. Each screw mechanism 1 is connected with a synchronous pulley 11, and under the linkage of a synchronous belt 12, the same rotation angular speed is kept. In the present embodiment, the motor 10 is disposed on the upper surface of the first support plate 4, and the plurality of timing pulleys 11 are disposed on the lower surface of the first support plate 4. In other embodiments, the motor 10 or the synchronous pulley 11 may be disposed at other positions, and the technical effect of synchronously rotating the screw mechanism 1 may also be achieved.

Fig. 2 to 4 particularly show the first screw 7 and the second screw 8 as specific examples of the screw mechanism 1 in the present embodiment. As shown in fig. 5, the first screw 7 and the second screw 8 are both connected to the second support plate 13 through the bearing seat 9 and connected to the first support plate 4 through the bearing sleeve 14. And can rotate about its own shaft portion 102 while maintaining its position relative to the first support plate 4 and the second support plate 13. As shown in fig. 6, the synchronous pulley 11 disposed below the first support plate 4 is also connected to the bearing sleeve 14, so that when the synchronous pulley 11 is rotated by the synchronous belt 12, the first screw 7 and the second screw 8 can be rotated at the same time. The first screw 7 and the second screw 8 have the same structure, and the pitch of the first screw is not constant along the axial direction, but gradually increases from top to bottom, taking fig. 6 as an example. In particular, in the present embodiment, H1, H2 and H3 are preferably H1 ═ 101 mm; h2 ═ 122 mm; h3 ═ 144 mm. Because pitch is crescent at the pivoted in-process, the muscle limit of magazine moves down under the effort of screw thread, is forced to increase the relative height between the magazine simultaneously, and when the relative height between the magazine was greater than the height of magazine itself, the magazine was changed into the separation mode from the stacked state promptly.

In the present embodiment, the initial angles of the first screw 7 and the second screw 8 are set to be the same, but the rotational direction and the distribution direction of the flights are set to be opposite. Although the relative height between the cartridges can be increased by setting the rotation directions of the first screw 7 and the second screw 8 to be the same, the screw thread generates a downward force for separating the cartridges and also generates a circumferential frictional force, and for the cartridges, a frictional force in the horizontal direction is received. When the rotation directions of the first screw 7 and the second screw 8 are the same, the two screws generate horizontal friction forces in the same direction on the material box, so that the material box cannot keep the original position and moves in the horizontal direction. Therefore, in the embodiment, the rotation directions of the first screw 7 and the second screw 8 are preferably set to be opposite, so that the horizontal acting forces generated by the two screws on the material box are equal in magnitude and opposite in direction, and the material box is prevented from moving horizontally. At the same time, the pitch distribution of the first screw 7 and the second screw 8 is the same, but the rotation directions of the threads are opposite, thereby ensuring that the descending speeds of the threads are kept synchronous during the rotation at the same speed but in opposite directions, so that the material box is kept horizontal during the separation process. In other embodiments, the first screw 7 and the second screw 8 may rotate at different rates, or may not have exactly the same pitch profile despite the same rate of rotation. Although the horizontal state of the material box in the separation process cannot be guaranteed, the technical effect of box separation can be met for the material box which is not loaded with goods in the stacking state.

In this embodiment, two sets of the first screw 7 and the second screw 8 are provided, and the positions of the two sets of the first screw 7 and the second screw 8 are distributed as shown in fig. 4, the two sets of the first screw 7 and the second screw 8 are respectively located at two sides of the apparatus, and the direction of the arrow in fig. 4 is an optional direction of the movement of the transmission mechanism 6. The two sets of first screws 7 and second screws 8 are arranged in a position parallel to the transport direction of the transport mechanism 6 and therefore do not prevent the separated cartridges from being transported out of the device. The advantage of this embodiment is that, two sets of screws counter-rotate each other respectively, and the horizontal direction frictional force that produces to the magazine is 0, therefore the magazine motion stability is high. In addition, the arrangement of the two groups of screws enables the device to generate enough box separating acting force so as to be suitable for separating and stacking tighter material boxes.

As shown in fig. 7, it is a bottom view of the present embodiment, so that the main structure of the driving assembly 5 is shown. Wherein the motor 10 is in this embodiment arranged on the upper surface of the first support plate 4 and therefore not shown in fig. 7. In this embodiment, nine synchronous pulleys 11 are disposed on the lower surface of the first support plate 4 and are connected by a synchronous belt 12. The outer diameter of each synchronous pulley 11 is the same, so that the angular rate of rotation of all nine synchronous pulleys 11 is the same under the drive of the motor 10. The synchronous pulleys 11 connected with the first screw 7 and the second screw 8 rotate in opposite directions.

Fig. 8 is a schematic diagram showing the relative height difference of the magazine during the separation process of the device. Here, h5 is the height of the magazine itself, and is preferably 100 mm. The relative height difference from top to bottom of the material box in the embodiment is preferably as follows: h 1:59mm; h2 ═ 90 mm; h3 ═ 92 mm; h4 ═ 96 mm; when the cartridges move to the lower limit height shown as h4 in fig. 8, the relative height difference between the cartridges has exceeded 100mm, i.e. the cartridges are no longer in the stacked state but are in the separated state.

The operation principle of this embodiment is specifically that the stacked cartridges are placed into the opening of the second support plate 13 from above, and since the horizontal dimension of the loading portion of the cartridges is slightly smaller than the so-called area of the four screws, and the dimension of the rib side of the cartridges is slightly larger than the area surrounded by the four screws, the rib side of the first cartridge (the lowermost cartridge in the stacked state) can be "hung" on the thread of the screw. With the rotation of the screw, the screw thread of the screw moves downwards, and the cartridges in a stacked state move downwards along with the screw thread. When one of the screws rotates for one circle (the rotation angular rates of the four screws are the same, so that the screws all rotate for one circle), due to the proper arrangement of the screw pitch, the thread end parts of the screws can enter the space above the rib edge of the first material box and below the rib edge of the second material box. The screw pitch is larger downwards as the screw is turned, forcing the relative height between two adjacent cartridges to increase. When the relative height between two adjacent cartridges is greater than or equal to the height of the cartridges themselves, the first cartridge is changed from the stacked state to the separated state.

Example 2:

fig. 9-11 are schematic structural views of another embodiment of the present application. Unlike the previous embodiment, the present embodiment employs only 3 screw mechanisms 1. Only one screw is provided on the other side, except for the first screw 7 and the second screw 8. The advantage that sets up like this has reduced the setting of a screw rod, has also reduced synchronous pulley 11's in the actuating mechanism 5 quantity simultaneously for the structure is further simplified, under the prerequisite that guarantees that the magazine can steadily separate, further reduces production assembly cost.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the teachings of this invention without undue experimentation.
