Description

Technical Field

[0001] This utility model relates to the field of material transfer technology, and in particular to a variable diameter bar box and its transfer device. Background Technology

[0002] The cigarette manufacturing process involves various rod-shaped materials, such as... Figure 1 The image shows a common rod-shaped cigarette. Its two ends often have different diameters; the diameter ΦD1 of end A (the filter end) is slightly larger than the diameter ΦD2 of end B (the tobacco end). Furthermore, end A is more compact than end B. Therefore, after being compressed, end A will deform less than end B. After the rod-shaped materials are produced, they need to be transferred, for example, transferring variable-diameter rods in batches from the manufacturing workshop on the first floor to the packaging workshop on other floors. Obviously, many rods need to be placed in material boxes for transfer to improve efficiency and operability. Therefore, the rod-shaped cigarettes in the material boxes will be compressed in the radial direction, increasing the diameter change of the cigarettes in the axial direction.

[0003] In the existing technology, due to the above two reasons (the diameter ΦD1 at end A is slightly larger than the diameter ΦD2 at end B; the compactness of end A of the variable diameter bar is greater than that of end B, and the deformation of end A after compression is less than that of end B), when transferring and conveying variable diameter bars, multiple variable diameter bars 1 will accumulate in the material box, resulting in the following situation: Figure 2 The tilting phenomenon shown indicates that the cumulative height H1 at end A is greater than the cumulative height H2 at end B, which causes the variable diameter bar stock to fall during the transfer process.

[0004] In addition, the current cigarette manufacturing process mainly relies on manual labor to transfer the material boxes to the destination via shelves (or trolleys), and then manually move the material boxes on the shelves (or trolleys) to the storage racks or packaging conveyor lines. Manual transfer is inefficient, and the variable diameter rods are more likely to fall off during the back-and-forth handling.

[0005] In summary, current variable diameter bar stock transfer processes suffer from problems such as easy bar stock falling and low efficiency of manual transfer. There is an urgent need for a variable diameter bar stock transfer solution to achieve automated transfer with zero drop of variable diameter bar stock. Utility Model Content

[0021] Figure 3 This is a structural schematic diagram of a variable diameter bar feed box provided in an embodiment of the present utility model, as shown below. Figure 3 As shown, the variable diameter bar stock box 2 includes: a base 22, a left wall 21, a right wall 23, and a rear wall 24; wherein, the top of the base 22 has a sloping structure; the left wall 21 and the right wall 23 are respectively disposed on the left and right sides of the base 22, the bottom of the right side of the left wall 21 is fixedly connected to the left side of the base 22, and the bottom of the left side of the right wall 23 is fixedly connected to the right side of the base 22; the rear wall 24 is disposed on the rear side of the base 22, and the bottom of the rear wall 24 is fixedly connected to the base 22; the base 22, the left wall 21, the right wall 23, and the rear wall 24 surround to form a four-sided closed cavity structure to accommodate multiple variable diameter bars.

[0025] In some embodiments, such as Figure 7 and Figure 8 As shown, a clamping area f is provided on the right wall 23, and a second rectangular rib 232 is provided on the upper side of the clamping area f.

Through precise lateral positioning, the connecting rod 331 of the connecting assembly 3 is aligned with the U-shaped groove of the interlocking frame 4 in its extension direction. The high position is defined as a position where the top surface of the U-shaped groove is higher than the upper surface of the connecting rod 331, and the bottom of the U-shaped groove is lower than the lower surface of the connecting rod 331. This high position can be preset or obtained by real-time detection of the current height of the connecting rod 331.

[0037] S14: The transport vehicle 5 lowers to a low position with the U-shaped frame 4 and places several fully loaded variable diameter bar boxes 2 on the connecting bracket 33; wherein, the low position is a position in which the top surface of the U-shaped groove is lower than the lower surface of the connecting rod 331.

[0038] S15: The transport vehicle 5 moves horizontally away from the connecting assembly 3 along the extension direction of the connecting rod 331, so as to exit the projection range of the connecting assembly 3.

[0040] Figure 15 This diagram illustrates a system for transporting multiple sets of variable-diameter bar boxes using a racking system. The transfer control process is as follows: S21: Place several sets of fully loaded variable diameter bar boxes on the multi-layer shelf 6; wherein, each shelf layer contains a set of variable diameter bar boxes consisting of several fully loaded variable diameter bar boxes 2. S22: Transport vehicle 5 moves to the bottom of shelf 6; S23: Align the center of transport vehicle 5 with the center of shelf 6; S24: Transport vehicle 5 lift rack 6 off the ground; S25: The transport vehicle 5 transfers the shelf 6 to the designated destination and lowers the shelf 6 to the ground; S26: The transport vehicle 5 moves out of the projection range of the shelf 6.

[0041] The handling method in steps S21-S25 can realize the large-scale group handling of material boxes.
