Description

Technical Field

[0001] This utility model relates to food and pharmaceutical packaging equipment, and more particularly to a stacking device for patch products. Background Technology

[0002] After being cut, various types of patches, such as hot melt adhesives, gels, and traditional Chinese medicine plasters, generally need to be stacked and then conveyed to an inner packaging machine for inner packaging. Depending on the efficacy, the treatment course for each patch product may differ, therefore the number of patches per bag needs to be determined based on the specific situation. Currently, a common method is to use a feeding mechanism to transport a set number of patches to each hopper. When the conveyor belt moves to the bottom of the hopper, the hopper opens, and the stacked patches fall onto the conveyor belt, which continues to transport them to the inner packaging machine for packaging. However, after cutting, defective products from the upstream process need to be rejected, resulting in inconsistent patch stacking numbers in each hopper (the number of defective products in each hopper is less). This necessitates manual replenishment or downstream inspection to remove bags with insufficient stacking numbers. Manual replenishment has low automation, high labor intensity, and the risk of incorrect patch counts; downstream inspection and rejection results in waste of qualified products and increases production costs. Furthermore, the existing silo stacking mechanism is relatively complex and occupies a large space. Additionally, many types of adhesives have high viscosity, which can easily cause jamming during dispensing, thus affecting the normal operation of the equipment. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a stacking device for patch products that can accurately stack the quantity, eliminate the need for manual replenishment, and avoid waste of qualified products.

[0004] This utility model further provides a stacking method for the above-mentioned patch product stacking device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A patch product stacking device includes a feeding mechanism, a discharging mechanism, and multiple hoppers. Each hopper is equipped with a counting component and a first stacking mechanism and a second stacking mechanism that can be opened and closed. The second stacking mechanism is located below the first stacking mechanism, and the discharging mechanism is located below the second stacking mechanism. The first stacking mechanism includes rotating shafts arranged parallel to both sides of the hopper and rotating in opposite directions. The rotating shafts are provided with multiple support members along the axial direction for carrying the products.

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

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

[0009] As a further improvement to the above technical solution: the surfaces of the support member and the pushing member are provided with an anti-sticking layer.

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

[0011] As a further improvement to the above technical solution: the second stacking mechanism includes a first pallet, a second pallet, a first telescopic drive member for driving the first pallet to reciprocate, and a second telescopic drive member for driving the second pallet to reciprocate, wherein the first telescopic drive member and the second telescopic drive member are arranged opposite to each other on both sides of the hopper.

[0012] As a further improvement to the above technical solution: both the first tray and the second tray are provided with multiple protrusions.

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

[0016] S1. The feeding mechanism simultaneously feeds the patch to the first stacking mechanism of each hopper, and the counting component records the number of patches stacked.

[0017] S2. When the number of patches stacked reaches the target value, the first stacking mechanism opens, the stacked patches fall onto the second stacking mechanism, and then the first stacking mechanism closes until the first stacking mechanism of each hopper is fully opened.

[0018] S3. The second stacking mechanism of each hopper is fully opened, and the stacked adhesive falls onto the discharge mechanism.

[0019] Compared with the prior art, the advantages of this utility model are:

[0020] This utility model discloses a patch stacking device. The feeding mechanism feeds patches to the first stacking mechanism of each hopper. The counting component records the stacking quantity of each hopper until the target quantity is reached. At this point, the first stacking mechanism can be opened to allow the stacked patches to fall onto the second stacking mechanism below. Then, the first stacking mechanism is closed to continue the next round of stacking. This helps to ensure the accuracy of the stacking quantity in each hopper and improves production efficiency. It eliminates the need for manual replenishment or downstream inspection and rejection, thus avoiding waste of qualified products. The first stacking mechanism includes rotating shafts located on both sides of the hopper and rotating in opposite directions. The rotating shafts are provided with multiple support members along the axial direction, which allows the patches to fall downwards simultaneously from all points along the axial direction of the rotating shaft. The overall structure is compact and occupies little space, which helps to achieve a matrix distribution of multiple hoppers and reduce the size of the device.

[0021] The present invention discloses a stacking method for a patch stacking device. A feeding mechanism feeds patches to the first stacking mechanism of each hopper. A counting component records the stacking quantity of each hopper until a target quantity is reached. At this point, the first stacking mechanism opens, allowing the stacked patches to fall onto the second stacking mechanism below. Then, the first stacking mechanism closes, allowing for the next round of stacking. This method ensures accurate stacking quantities in each hopper and improves production efficiency. After all patches have been transferred from the first stacking mechanism of each hopper to the second stacking mechanism below, the second stacking mechanism opens completely to allow the patches to fall, preventing material shortages at certain points in the dispensing mechanism and ensuring high reliability.

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

[0036] Example 1

[0037] Figures 1 to 7This invention illustrates an embodiment of a patch-type product stacking device. The device includes a feeding mechanism 1, a discharging mechanism, and multiple hoppers 3. Each hopper 3 is equipped with a counting component 2 and a first stacking mechanism 4 and a second stacking mechanism 5, which can be opened and closed. The second stacking mechanism 5 is located below the first stacking mechanism 4, and the discharging mechanism is located below the second stacking mechanism 5. The first stacking mechanism 4 includes rotating shafts 41 arranged parallel to both sides of the hoppers 3 and rotating in opposite directions. Multiple support members 42 for supporting the products are arranged axially along the rotating shafts 41. Preferably, the counting component 2 is a photoelectric sensor, and the support members 42 can be, for example, support rods or support strips. The discharging mechanism can be, for example, a discharging conveyor belt. Preferably, the support members 42 on both rotating shafts 41 are aligned.

[0038] In this embodiment, the patch stacking device uses a feeding mechanism 1 to feed patches onto the first stacking mechanism 4 of each hopper 3. A counting component 2 records the stacking quantity of each hopper 3 until a target quantity is reached. At this point, the first stacking mechanism 4 can be opened, allowing the stacked patches to fall onto the second stacking mechanism 5 below. Then, the first stacking mechanism 4 is closed, allowing for the next round of stacking. This method ensures accurate stacking quantities in each hopper 3 and improves production efficiency, eliminating the need for manual replenishment or downstream inspection and rejection, thus preventing waste of qualified products. The first stacking mechanism 4 includes rotating shafts 41 located on both sides of the hopper 3 and rotating in opposite directions. Multiple support members 42 are provided along the axial direction of the rotating shafts 41, allowing patches to fall simultaneously downwards along the shafts 41. The overall structure is compact, occupying little space, and facilitates a matrix distribution of multiple hoppers 3, reducing the overall size of the device (see details). Figure 2 and Figure 3 The servo motors 45 of the two rows of first stacking mechanisms 4 are arranged opposite each other on the front and rear sides of the hopper 3, and the two rows of hoppers 3 can be placed close together to save space.

[0039] See details Figure 5 and Figure 6 Furthermore, the rotating shaft 41 is provided with multiple pushing members 43 along the axial direction. These pushing members 43 and multiple supporting members 42 are arranged alternately along the axial direction of the rotating shaft 41. The included angle between the supporting members 42 and the pushing members 43 is α, where 0° < α ≤ 120°. When the rotating shaft 41 rotates, if the adhesive adheres and cannot fall smoothly downwards, the pushing members 43 can push the adhesive downwards, which helps avoid adhesion jamming and improves the reliability of the first stacking mechanism 4. In this embodiment, α = 90°. The pushing members 43 do not occupy the space above the supporting members 42, thus not affecting the adhesive stacking height, and can promptly push the stacked adhesive to the lower second stacking mechanism 5. Of course, in other embodiments, α can also be adjusted appropriately. The pushing members 43 can be, for example, pushing rods or pushing strips. Preferably, the pushing members 43 on both sides of the rotating shaft 41 are aligned.

[0040] Furthermore, in this embodiment, the pushing member 43 is provided with an air blowing channel 44. If the pushing member 43 still cannot push the patch to the second bonding mechanism 5, compressed gas can be introduced through the air blowing channel 44 to prevent the patch from sticking and jamming, thereby further improving the reliability of the first stacking mechanism 4.

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

[0042] See details Figures 2 to 5 In this embodiment, one rotating shaft 41 is connected to a servo motor 45, and a transmission gear set 46 is provided between the two rotating shafts 41. During operation, the servo motor 45 drives the rotating shaft 41 connected to it 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, realizing opening and closing. The structure is simple and the operation is reliable. The servo motor 45 can precisely control the rotation angle of the rotating shaft 41. Of course, in other embodiments, the two rotating shafts 41 can also be equipped with servo motors 45 respectively, but since the two rotating shafts 41 need to rotate synchronously in opposite directions, the control difficulty increases, and the cost also increases.

[0043] See details Figure 5 and Figure 6 In this embodiment, the second stacking mechanism 5 includes a first tray 51, a second tray 52, a first telescopic drive 53 for reciprocating the first tray 51, and a second telescopic drive 54 for reciprocating the second tray 52. ​​The first telescopic drive 53 and the second telescopic drive 54 are arranged opposite each other on both sides of the hopper 3. After the adhesive is stacked on each of the second stacking mechanisms 5, the first telescopic drive 53 and the second telescopic drive 54 respectively drive the first tray 51 and the second tray 52 to move away from each other, thereby opening the mechanism and allowing the adhesive to fall onto the discharge mechanism below. The structure is simple and reliable. Preferably, a guide groove can be provided on the hopper 3 to guide the reciprocating movement of the first tray 51 and the second tray 52 and prevent deviation. The first telescopic drive 53 and the second telescopic drive 54 can be, for example, a cylinder, an electric push rod, or a lead screw and nut assembly.

[0044] See details Figure 2 , Figure 3 and Figure 5In this embodiment, both the first pallet 51 and the second pallet 52 are provided with multiple protrusions 55. The six hoppers 3 in each row share a set of second stacking mechanisms 5, which can simplify the structure, save space and reduce costs. Correspondingly, the first pallet 51 and the second pallet 52 need to be set to be relatively long. Setting the first pallet 51 and the second pallet 52 as a concave-convex structure is beneficial to improving the load-bearing capacity of the first pallet 51 and the second pallet 52 and avoiding deformation.

[0045] See details Figure 1 and Figure 7 In this embodiment, the feeding mechanism 1 includes a feeding robot 11 and a suction cup 12 mounted on the feeding robot 11. The suction cup 12 is provided with multiple adsorption parts 13. Further, the multiple hoppers 3 are arranged in a matrix (specifically, two rows and six columns), and the multiple adsorption parts 13 are arranged in a matrix (specifically, three rows and six columns). During feeding, the adsorption parts 13 use vacuum to adsorb the adhesive. The feeding robot 11 moves each adsorption part 13 above each hopper 3, and then the vacuum is broken by the adsorption parts 13, allowing the adhesive to fall onto the first stacking mechanism 4 inside the hopper 3. This structure allows for simultaneous feeding of multiple rows and columns of hoppers 3, resulting in fast feeding speed and high efficiency. For defective products, the corresponding adsorption parts 13 do not adsorb, thus completing the rejection process. The structure is reasonable and effective.

[0046] Example 2

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

[0048] S1. The feeding mechanism 1 simultaneously feeds the patch onto the first stacking mechanism 4 of each material bin 3, and the counting component 31 records the number of patch stacks.

[0049] S2. When the number of patches stacked reaches the target value, the first stacking mechanism 4 opens, and the stacked patches fall onto the second stacking mechanism 5. Then the first stacking mechanism 4 closes until all the first stacking mechanisms 4 of each hopper 3 are opened (because defective products need to be removed, the number of patches stacked in each hopper 3 is not consistent, or the stacking speed is not consistent. The hopper 3 corresponding to defective products requires more feeding times and longer time).

[0050] S3, the second stacking mechanism 5 of each hopper 3 is fully opened, and the stacked adhesive falls onto the discharge mechanism.

[0051] In this embodiment, the stacking method of the patch product stacking device involves the feeding mechanism 1 feeding patches onto the first stacking mechanism 4 of each hopper 3. The counting component 2 records the stacking quantity of each hopper 3 until the target quantity is reached. At this point, the first stacking mechanism 4 opens, allowing the stacked patches to fall onto the second stacking mechanism 5 below. Then, the first stacking mechanism 4 closes, allowing the next round of stacking to continue. This method helps ensure the accuracy of the stacking quantity in each hopper 3 and improves production efficiency. After all the patches have been transferred from the first stacking mechanism 4 of each hopper 3 to the second stacking mechanism 5 below, or after all patches have been stacked on each second stacking mechanism 5, the second stacking mechanism 5 opens completely to allow the patches to fall. This method helps prevent material shortages in some parts of the dispensing mechanism and ensures high reliability.

[0052] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
