Description

Technical Field

[0001] The invention relates to food and medicine packaging equipment and methods, and in particular to a patch product stacking device and a stacking method thereof. Background Art

[0002] After cutting, various types of patches such as hot melt adhesives, gels, and Chinese medicine patches generally need to be stacked and then transported to the inner packaging machine for inner packaging. According to the efficacy of the drug, the course of treatment for each patch product may be different, so the number of patches in each bag needs to be determined according to the actual situation. At present, the more common method is to use the feeding mechanism to transport a set number of patches to each silo. When the conveyor belt moves to the bottom of the silo, the silo opens, and the stacked patches fall onto the conveyor belt, which is then transported to the inner packaging machine for packaging. However, after cutting, unqualified products produced in the upstream process need to be removed, resulting in inconsistent numbers of patches stacked in each silo (the number of silos corresponding to unqualified products is relatively small). For this reason, manual feeding is required, or testing is performed at the downstream station and the packaging bags with a small number of stacks are removed. Manual feeding has a low degree of automation, high labor intensity, and the risk of incorrect number of feeding pieces; testing and removal at the downstream station will cause waste of qualified products and increase production costs. In addition, the stacking mechanism of the existing silo is relatively complex and occupies a large space. At the same time, many types of patches have high viscosity and are prone to get stuck when dropping, thus affecting the normal operation of the equipment. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a patch product stacking device which can accurately stack the quantity, does not require manual feeding, and avoids the waste of qualified products.

[0004] The present invention further provides a stacking method of the above-mentioned patch product stacking device.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A patch product stacking device comprises a loading mechanism, a discharging mechanism and a plurality of silos, wherein the silos are provided with a counting component and a first stacking mechanism and a second stacking mechanism that can be opened and closed, wherein the second stacking mechanism is arranged below the first stacking mechanism, and the discharging mechanism is arranged below the second stacking mechanism, wherein the first stacking mechanism comprises a rotating shaft that is arranged parallel to both sides of the silo and rotates in opposite directions, and wherein the rotating shaft is provided with a plurality of supporting members for carrying products along the axial direction.

[0007] As a further improvement of the above technical solution: the rotating shaft is axially provided with a plurality of pushing members, the plurality of pushing members and the plurality of supporting members are alternately arranged axially along the rotating shaft, and the angle between the supporting members and the pushing members is α, 0°<α≤120°.

[0008] As a further improvement of the above technical solution: an air blowing channel is provided inside the pushing member.

[0009] As a further improvement of the above technical solution: an anti-sticking layer is provided on the surfaces of the support member and the push member.

[0010] As a further improvement of the above technical solution: one of the rotating shafts is connected to the servo motor, and a transmission gear set is provided between the two rotating shafts.

[0011] As a further improvement of the above technical solution: the second stacking mechanism includes a first pallet, a second pallet, a first telescopic drive component for driving the first pallet to move back and forth, and a second telescopic drive component for driving the second pallet to move back and forth, and the first telescopic drive component and the second telescopic drive component are arranged opposite to each other on both sides of the silo.

[0012] As a further improvement of the above technical solution: the first support plate and the second support plate are both provided with a plurality of protrusions.

[0013] As a further improvement of the above technical solution: the feeding mechanism includes a feeding robot and a suction cup arranged on the feeding robot, and the suction cup is provided with a plurality of adsorption parts.

[0014] As a further improvement of the above technical solution: the plurality of silos are distributed in a matrix, and the plurality of adsorption parts are distributed in a matrix.

[0015] A stacking method of the above-mentioned patch product stacking device comprises the following steps:

[0016] S1, the feeding mechanism simultaneously feeds the patches to the first stacking mechanism of each bin, and the counting component records the number of patches stacked;

[0017] S2. When the number of stacked patches reaches the target value, the first stacking mechanism is opened, the stacked patches fall onto the second stacking mechanism, and then the first stacking mechanism is closed until all the first stacking mechanisms of the silos are opened;

[0018] S3. The second stacking mechanisms of all silos are opened, and the stacked patches fall onto the discharging mechanism.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] The patch product stacking device disclosed in the present invention has a feeding mechanism that feeds the patches to the first stacking mechanism of each silo, and records the stacking quantity of each silo through a counting component until a target quantity value is reached. At this time, the first stacking mechanism can be opened to allow the stacked patches to fall onto the second stacking mechanism below. The first stacking mechanism is then closed, and the next round of stacking can be continued, which is beneficial to ensuring the accuracy of the stacking quantity in each silo and improving production efficiency. There is no need for manual feeding, or detection and rejection at downstream stations, which causes waste of qualified products.

[0035] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Embodiment 1

[0037] Figures 1 to 7An embodiment of a patch product stacking device of the present invention is shown. The patch product stacking device of this embodiment includes a feeding mechanism 1, a discharging mechanism and multiple silos 3. The silo 3 is provided with a counting component 2 and a first stacking mechanism 4 and a second stacking mechanism 5 that can be opened and closed. The second stacking mechanism 5 is arranged below the first stacking mechanism 4, and the discharging mechanism is arranged below the second stacking mechanism 5. The first stacking mechanism 4 includes a rotating shaft 41 that is arranged parallel to both sides of the silo 3 and rotates in opposite directions. The rotating shaft 41 is axially provided with multiple support members 42 for carrying products. Among them, the counting component 2 preferably adopts various types of photoelectric sensors, the support member 42 can be, for example, a support rod, a support bar, etc., and the discharging mechanism can be, for example, a discharging mesh belt, etc. Preferably, the support members 42 on the rotating shafts 41 on both sides are aligned.

[0038] In the patch product stacking device of this embodiment, the feeding mechanism 1 feeds the patches to the first stacking mechanism 4 of each silo 3, and records the stacking quantity of each silo 3 through the counting component 2 until the target quantity value is reached. At this time, the first stacking mechanism 4 can be opened to make the stacked patches fall onto the second stacking mechanism 5 below, and then the first stacking mechanism 4 is closed, and the next round of stacking can be continued, which is conducive to making the stacking quantity in each silo 3 accurate and improving production efficiency, without the need for manual feeding, or detection and rejection at downstream stations, resulting in waste of qualified products; the first stacking mechanism 4 includes a rotating shaft 41 arranged on both sides of the silo 3 and rotating in opposite directions, and the rotating shaft 41 is axially provided with a plurality of supporting members 42, so that the patches can be simultaneously dropped downward along the rotating shaft 41 to various places, and the overall structure is compact, occupies less space, and is conducive to realizing the matrix distribution of multiple silos 3 and reducing the volume of the device (see for details). Figure 2 and Figure 3 The servo motors 45 of the two rows of first stacking mechanisms 4 are relatively arranged at the front and rear sides of the silo 3, and the two rows of silos 3 can be close together to save space).

[0039] See Figure 5 and Figure 6 , further, the rotating shaft 41 is axially provided with a plurality of push pieces 43, and the plurality of push pieces 43 and the plurality of support members 42 are alternately arranged axially along the rotating shaft 41, and the angle between the support member 42 and the push piece 43 is α, 0°<α≤120°. When the rotating shaft 41 rotates, if the patch is sticky and cannot fall down smoothly, the patch can be pushed downward by the push piece 43, which is conducive to avoiding sticking and jamming, and improving the reliability of the first stacking mechanism 4. In the present embodiment, α=90°, the push piece 43 neither occupies the space above the support member 42, affects the stacking height of the patch, and can timely push the stacked patch to the second stacking mechanism 5 below. Of course, in other embodiments, α can also be appropriately adjusted. Wherein, the push piece 43 can be, for example, a push rod, a push strip, etc., and preferably, the push pieces 43 on the rotating shafts 41 on both sides are aligned.

[0040] Furthermore, in this embodiment, a blowing channel 44 is provided inside the pushing member 43. If the pushing member 43 still cannot push the patch to the second patching mechanism 5, compressed gas can be introduced through the blowing channel 44 to prevent the patch from sticking to the material, further improving the reliability of the first stacking mechanism 4.

[0041] As a preferred embodiment, the surfaces of the support member 42 and the push member 43 are provided with an anti-sticking layer (not shown in the figure), which helps to prevent the patch from sticking to the support member 42 and the push member 43, and further improves the reliability of the first stacking mechanism 4.

[0042] See Figures 2 to 5 In this embodiment, one of the rotating shafts 41 is connected to the servo motor 45, and a transmission gear set 46 is provided between the two rotating shafts 41. When working, the servo motor 45 drives the rotating shaft 41 connected thereto to rotate, and at the same time drives the other rotating shaft 41 to rotate synchronously in the opposite direction through the transmission gear set 46, thereby driving the support member 42 to rotate up and down to achieve opening and closing, with a simple structure and reliable operation; the servo motor 45 can accurately control the rotation angle of the rotating shaft 41. Of course, in other embodiments, the two rotating shafts 41 can also be configured with servo motors 45 respectively, but since the two rotating shafts 41 need to rotate synchronously in the opposite direction, the control difficulty increases and the cost also increases.

[0043] See Figure 5 and Figure 6 In the present embodiment, the second stacking mechanism 5 includes a first support plate 51, a second support plate 52, a first telescopic driving member 53 for driving the first support plate 51 to move back and forth, and a second telescopic driving member 54 for driving the second support plate 52 to move back and forth, and the first telescopic driving member 53 and the second telescopic driving member 54 are arranged relatively on both sides of the silo 3. After the patches are stacked on each second stacking mechanism 5, the first telescopic driving member 53 and the second telescopic driving member 54 respectively drive the first support plate 51 and the second support plate 52 to move away from each other, so as to realize opening, and the patch falls on the discharging mechanism below, which is simple in structure and reliable. Preferably, a guide groove can be set on the silo 3 to provide a guiding effect for the reciprocating movement of the first support plate 51 and the second support plate 52 to avoid deviation. Wherein, the first telescopic driving member 53 and the second telescopic driving member 54 can be, for example, a cylinder, an electric push rod, a screw nut pair, etc.

[0044] See Figure 2 , Figure 3 and Figure 5In this embodiment, the first support plate 51 and the second support plate 52 are both provided with a plurality of convex portions 55. The six silos 3 in each row share a set of second stacking mechanisms 5, which can simplify the structure, save space and reduce costs. Accordingly, the first support plate 51 and the second support plate 52 need to be set longer. The first support plate 51 and the second support plate 52 are set as concave-convex structures, which is conducive to improving the load-bearing capacity of the first support plate 51 and the second support plate 52 and avoiding deformation.

[0045] See Figure 1 and Figure 7 In this embodiment, the feeding mechanism 1 includes a feeding robot 11 and a suction cup 12 arranged on the feeding robot 11, and a plurality of adsorption parts 13 are arranged on the suction cup 12. Furthermore, a plurality of silos 3 are distributed in a matrix (specifically two rows and six columns), and a plurality of adsorption parts 13 are distributed in a matrix (specifically three rows and six columns). During feeding, the adsorption part 13 uses vacuum to adsorb the patch, and the feeding robot 11 drives each adsorption part 13 to move above each silo 3, and then the adsorption part 13 breaks the vacuum, and the patch can fall onto the first stacking mechanism 4 in the silo 3. This structure can realize the simultaneous feeding of multiple rows and columns of silos 3, with fast feeding speed and high efficiency. For unqualified products, the corresponding adsorption part 13 does not adsorb, and the waste can be eliminated, and the structure is reasonable and effective.

[0046] Embodiment 2

[0047] The stacking method of the patch product stacking device of this embodiment includes the following steps:

[0048] S1, the feeding mechanism 1 simultaneously feeds the patches to the first stacking mechanism 4 of each bin 3, and the counting component 31 records the number of the stacked patches;

[0049] S2. When the number of stacked patches reaches the target value, the first stacking mechanism 4 is opened, and the stacked patches fall onto the second stacking mechanism 5, and then the first stacking mechanism 4 is closed until all the first stacking mechanisms 4 of the silos 3 are opened (because unqualified products need to be rejected, the number of stacked patches in each silo 3 is not consistent, or the stacking speed is not consistent, and the silos 3 corresponding to unqualified products require more loading times and longer time);

[0050] S3. The second stacking mechanisms 5 of all the silos 3 are opened, and the stacked patches fall onto the discharging mechanism.

[0051] According to the stacking method of the patch product stacking device of the present embodiment, the loading mechanism 1 loads the patches onto the first stacking mechanism 4 of each silo 3, and records the stacking quantity of each silo 3 through the counting component 2 until the target quantity value is reached. At this time, the first stacking mechanism 4 is opened to allow the stacked patches to fall onto the second stacking mechanism 5 below, and then the first stacking mechanism 4 is closed, and the next round of stacking can be continued, which is beneficial to making the stacking quantity in each silo 3 accurate and improving production efficiency; when the first stacking mechanism 4 of each silo 3 has transferred all the patches to the second stacking mechanism 5 below, or when all the second stacking mechanisms 5 are stacked with patches, the second stacking mechanisms 5 are fully opened to discharge the patches, which is beneficial to preventing material shortage in some parts of the discharging mechanism and has good reliability.

[0052] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention should fall within the scope of protection of the technical solution of the present invention.
