Description

Technical Field

[0001] This utility model belongs to the technical field of packaging material conveying equipment, specifically relating to a batch conveying equipment for packaging materials such as medicine bottles. Background Technology

[0002] In the pharmaceutical industry, various bottles are common packaging materials. Currently, production lines typically use rotary bottle unloaders and reversible conveyor belts to transport bottled packaging materials. With this method, the bottles are transported close together on the conveyor belt, inevitably leading to collisions and breakage, which affects product quality. Furthermore, the collisions between adjacent bottles generate noise, impacting employee comfort. Utility Model Content

[0003] The purpose of this invention is to provide a packaging material conveying device that provides stable transmission and reduces noise.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A packaging material conveying device includes: a first conveyor belt and a second conveyor belt arranged sequentially and in the same conveying direction, wherein the conveying speed of the second conveyor belt is greater than the conveying speed of the first conveyor belt, and the first and second conveyor belts are intermittent conveyor belts; a first buffer plate disposed between the first and second conveyor belts, the first buffer plate being used to buffer packaging materials conveyed from the first conveyor belt to the second conveyor belt, the upper surface of the first buffer plate being flush with the upper surfaces of the first and second conveyor belts; a first push plate movable along a first direction, the first push plate being used to push the packaging materials located on the first conveyor belt forward, the first direction being the conveying direction of the first conveyor belt; under the push of the first push plate, the packaging materials on the first conveyor belt are moved in rows to the first buffer plate, and the packaging materials on the first buffer plate are moved in rows to the second conveyor belt.

[0006] In some embodiments, the system further includes a third conveyor belt, a second buffer plate, and a second pusher plate; the third conveyor belt is disposed at the discharge end of the second conveyor belt, the second buffer plate is disposed between the second conveyor belt and the third conveyor belt, and the upper surface of the second buffer plate is flush with the upper surface of the second conveyor belt and the upper surface of the third conveyor belt; the second pusher plate is movable along the first direction to push the packaging materials located on the second conveyor belt onto the second buffer plate and push the packaging materials on the second buffer plate onto the third conveyor belt; under the push of the second pusher plate, the packaging materials on the second conveyor belt are moved in rows onto the second buffer plate, and the packaging materials on the second buffer plate are moved in rows onto the third conveyor belt.

[0007] In some embodiments, the conveying direction of the third conveyor belt is perpendicular to the first direction.

[0008] In some embodiments, the second pusher plate is disposed at the discharge end of the second conveyor belt and can be raised and lowered in the vertical direction.

[0009] In some embodiments, the first push plate can be raised and lowered in a vertical direction.

[0010] In some embodiments, the first pusher plate is disposed at the feed end of the first conveyor belt.

[0011] In some embodiments, the first pusher plate moves synchronously with the first conveyor belt.

[0012] In some embodiments, the width of the first cache board is not less than 2 / 3 of the bottom width of the packaging material.

[0015] As can be seen from the above technical solution, this utility model sets up conveyor belts with different conveying speeds and sets up buffer plates at the junctions of the conveyor belts. The conveyor belts with different conveying speeds separate the entire stack of packaging materials at fixed distances, avoiding the bottles from squeezing and colliding with each other during conveying, which would cause the bottles to break. Before moving to the next conveyor belt, the packaging materials are first transferred on the buffer plate and then pushed forward as a whole by the pusher plate. This can make the bottled packaging materials be delivered to the next conveyor belt neatly and stably, which is conducive to improving product quality and reducing noise and the risk of collision of bottled packaging materials during the production process.

[0025] Reference Figures 1 to 5The packaging material conveying equipment in this embodiment includes a machine base 1, a first conveyor belt 2, a second conveyor belt 3, a third conveyor belt 4, an electrical control box 5, and a PLC control panel 6. The first conveyor belt 2, second conveyor belt 3, third conveyor belt 4, electrical control box 5, and PLC control panel 6 are all mounted on the machine base 1. The first conveyor belt 2, second conveyor belt 3, and third conveyor belt 4 are arranged sequentially. After the packaging materials such as bottles flow from the previous workstation, they are conveyed by the first conveyor belt 2 to the second conveyor belt 3, then by the second conveyor belt 3 to the third conveyor belt 4, and finally by the third conveyor belt 4 to the subsequent workstation. The conveying direction of the first conveyor belt 2 and the second conveyor belt 3 in this embodiment is (…). Figure 2 The directions indicated by the middle arrows are the same. The conveying directions of the first conveyor belt 2 and the second conveyor belt 3 are defined as the first direction, and the conveying direction of the third conveyor belt 4 is perpendicular to the first direction. In this embodiment, the first conveyor belt 2, the second conveyor belt 3, and the third conveyor belt 4 can be conventional motor-driven mesh belt conveyors or belt conveyors, and all of them are intermittent conveyor belts, that is, the conveyor belts stop after conveying a certain distance, then convey a certain distance again before stopping, and are not continuously operating continuous conveyor belts.

[0026] The first conveyor belt 2 and the second conveyor belt 3 have different conveying speeds, with the second conveyor belt 3 having a higher conveying speed than the first conveyor belt 2. The first conveyor belt 2 forms a transitional bottle feeding zone, while the second conveyor belt 3 forms a segmented, fixed-distance conveying zone. Because the second conveyor belt 3 has a higher conveying speed than the first conveyor belt 2, when the bottles and other packaging materials are delivered from the first conveyor belt 2 to the second conveyor belt 3, the second conveyor belt 3 will accelerate forward relative to the packaging materials on the first conveyor belt 2, thus creating a distance between it and the packaging materials in the next row, forming segmented, fixed-distance conveying.

[0027] A first buffer plate 7 is disposed between the first conveyor belt 2 and the second conveyor belt 3. The first buffer plate 7 is located after the discharge end of the first conveyor belt 2 and before the inlet end of the second conveyor belt 3. The packaging material must pass through the first buffer plate 7 before it can move onto the second conveyor belt 3. The upper surface of the first buffer plate 7 is flush with the upper surfaces of both the first conveyor belt 2 and the second conveyor belt 3. Figure 4 As shown, there is no height difference between the upper surface of the first buffer plate 7 and the upper surfaces of the first conveyor belt 2 and the second conveyor belt 3. The upper surfaces of all three are at the same height and flush with each other. This allows the packaging material to move from the first conveyor belt 2 to the first buffer plate 7, and from the first buffer plate 7 to the second conveyor belt 3. It is understood that the buffer plate is positioned between the two conveyor belts. To avoid affecting the normal operation of the conveyor belts, a certain gap can be left at the junction of the buffer plate and the conveyor belt. However, this gap will not affect the movement of the packaging material from the conveyor belt / buffer plate to the buffer plate / conveyor belt. As long as this gap is not wide enough to cause the packaging material to fall between the conveyor belt and the buffer plate, this gap can be set according to the size of the packaging material; no limitation is made here.

[0028] A first pusher plate 9 is provided at the feeding end of the first conveyor belt 2. The extension direction of the first pusher plate 9 is consistent with the width direction of the first conveyor belt 2, and its length corresponds to the width of the second conveyor belt 2. The first pusher plate 9 can move horizontally along a first direction, thereby pushing the entire stack of bottles placed on the first conveyor belt 2 forward. In some embodiments, the first pusher plate 9 can also be raised and lowered vertically, so as not to affect the feeding and movement of the bottle stack, and can adapt to packaging materials of different sizes by adjusting its height. In this embodiment, the raising and lowering of the first pusher plate 9 is controlled by a cylinder, and the forward and backward movement of the first pusher plate 9 is controlled by a motor + screw transmission structure.

[0029] In this embodiment, a third conveyor belt 4 is provided at the discharge end of the second conveyor belt 3. The conveying direction of the third conveyor belt 4 is perpendicular to the conveying directions of the first and second conveyor belts. The third conveyor belt 4 is a narrow conveyor belt, with a width adapted to the width of the packaging materials, used to convey the entire row of packaging materials outward. A second buffer plate 8 is provided between the second conveyor belt 3 and the third conveyor belt 4. The second buffer plate 8 is located after the discharge end of the second conveyor belt 3 and before the inlet end of the third conveyor belt 3. The packaging materials must pass through the second buffer plate 8 before moving onto the third conveyor belt 4. Similarly, the upper surface of the second buffer plate 8 is flush with the upper surface of the second conveyor belt 3 and the upper surface of the third conveyor belt 4. Figure 5 As shown, the packaging material can be moved from the second conveyor belt 3 to the second buffer plate 8, and from the second buffer plate 8 to the third conveyor belt 4.

[0030] A second pusher plate 10 is provided at the discharge end of the second conveyor belt 3. The structure of the second pusher plate 10 is the same as that of the first pusher plate 9. It can also move horizontally in the first direction, thereby pushing the packaging material on the second conveyor belt 3 forward onto the second buffer plate 8, and pushing the packaging material on the second buffer plate 8 onto the third conveyor belt 4. The second pusher plate 10 can be raised and lowered in the vertical direction. When the second pusher plate 10 rises, it does not hinder the packaging material on the second conveyor belt 3 from moving forward with the second conveyor belt 3.

[0031] A packaging material detection sensor 12 is installed at the inlet end of the third conveyor belt 4. The packaging material detection sensor 12 is used to detect whether there are bottles or other packaging materials on the inlet end of the third conveyor belt 4. If not, the second push plate 10 pushes the entire row of bottles on the second buffer plate 8 onto the third conveyor belt 4 according to the detection signal of the packaging material detection sensor 12. A counter 11 is installed at the outlet end of the third conveyor belt 4 to count the packaging materials conveyed by the third conveyor belt 4.

[0032] In some embodiments, the width of the buffer plate is at least 2 / 3 of the bottom width of the packaging material (the width of the packaging material is its dimension in the first direction), thereby effectively buffering the packaging material so that it can be stored on the buffer plate and stop moving forward. For example, when the packaging material is a bottle, the width of the buffer plate is at least 2 / 3 of the bottom diameter of the bottle.

[0033] The operation process of the packaging material conveying equipment in this embodiment will be described below with reference to the accompanying drawings, taking the bottle body as an example.

[0034] When the bottle stack is moved from the previous workpiece to the first conveyor belt 2 by the robot or other conveying equipment, the first conveyor belt 2 drives the entire stack of bottles to move forward; the first push plate 9 moves forward synchronously with the first conveyor belt 2.

[0035] When the first conveyor belt 2 moves the bottle stack to the first buffer plate 7, the first conveyor belt 2 stops running, and the first pusher plate 9 pushes the entire bottle stack forward one position, so that the bottles in the front row move onto the first buffer plate 7.

[0036] After a row of bottles is pushed onto the first buffer plate 7, the first pusher plate 9 continues to push the bottles on the first conveyor belt 2 forward by one position. The next row of bottles is pushed onto the first buffer plate 7, and at the same time, the bottles that were originally on the first buffer plate 7 are pushed onto the second conveyor belt 3.

[0037] The second conveyor belt 3 carries the bottles pushed onto it forward. Since the conveying speed of the second conveyor belt 2 is greater than that of the first conveyor belt 2, the bottles in adjacent rows can be separated by a certain distance, so that the bottles in adjacent rows do not squeeze each other, avoid collision damage between bottles and noise.

[0038] When the second conveyor belt 3 carries rows of bottles at intervals to the second buffer plate 8, the second conveyor belt 3 stops running, the second pusher plate 10 descends and pushes the first row of bottles forward one position, so that the first row of bottles moves onto the second buffer plate 8.

[0039] If the packaging material detection sensor 12 detects that the feed end of the third conveyor belt 4 is empty, it sends a corresponding detection signal. Then, the second pusher plate 10 further pushes the entire row of bottles on the front row of the second buffer plate 8 onto the third conveyor belt 4, and the third conveyor belt 4 transports the bottles outward. The bottles can be counted by the counter 11 at the discharge end of the third conveyor belt 4.

[0040] This embodiment uses conveyor belts with different conveying speeds to separate stacks of packaging materials at fixed intervals, preventing bottles from crowding and colliding during transport, which could lead to bottle breakage and affect product quality. Furthermore, separating the bottles reduces noise from collisions during transport. A buffer plate is installed at the junction of the conveyor belts. Before moving to the next conveyor belt, the packaging materials transition on the buffer plate and are then pushed forward by a pusher plate, ensuring that the bottled packaging materials are neatly delivered to the next conveyor belt. The pusher plate can be raised and lowered and its height can be adjusted according to different packaging material specifications, improving its versatility.

[0041] The packaging material conveying equipment in this embodiment can be used not only for conveying packaging materials such as medicine bottles, but also for conveying other packaging materials such as boxes. It adopts an intermittent conveyor belt for fixed-distance segmented conveying and a buffer plate for transitional storage, which solves the problems of traditional discs that rotate continuously to sort bottles and require forward and reverse conveyor belts for sorting and feeding bottles. In the whole process, bottled packaging materials will collide with each other and the working environment is noisy. It effectively improves product quality and the comfort of the employee's working environment.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
