[0003] Existing automatic material dispensing devices change the material spacing by using springs placed between the materials. If the preset material dispensing spacing needs to be changed, the entire spring needs to be replaced. Furthermore, when the workload is large, the springs are prone to fatigue, failure, and other durability problems, resulting in high maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to provide a variable pitch material distribution device with high operating efficiency, low maintenance cost and good durability.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0008] The dispensing device includes a variable-pitch trough plate, a variable-pitch drive mechanism, and multiple adsorption mechanisms. The variable-pitch trough plate is mounted above the dispensing end and has multiple guide channels spaced apart along a second horizontal direction. One end of each guide channel is an adsorption end, and the other end is a variable-pitch end. The distance between any two adjacent variable-pitch ends is equal. The adsorption mechanism is slidably disposed between the variable-pitch trough plate and the bottom of the collection trough. A guide member is provided at the top of each adsorption mechanism and is located in the guide channel. Each adsorption mechanism can adsorb one product along the first horizontal direction. The variable-pitch drive mechanism is configured to drive the guide member to move from the adsorption end to the variable-pitch end.

[0009] The first horizontal direction is perpendicular to the second horizontal direction.

[0018] The rocker arm has a transmission block rotatably mounted on one end, which is slidably mounted in the guide hole. The other end of the rocker arm is rotatably connected to the connecting block. When the feeding drive mechanism can drive the eccentric wheel to rotate around its own center, the transmission block reciprocates in the guide hole, and both transmission rods can reciprocate in the second horizontal direction under the drive of the connecting block.

[0019] Preferably, the multiple guide plates can be divided into first guide plates and second guide plates according to their different lengths, the length of the first guide plate is greater than the length of the second guide plate, and a second guide plate is provided between any two adjacent first guide plates.

[0020] Preferably, the product is cylindrical, with the first guide plate and the second guide plate aligned with each other at the end near the dispensing device, and the length difference between the first guide plate and the second guide plate equal to the cross-sectional diameter of the product at the other end away from the dispensing device.

[0021] Preferably, the material dispensing device further includes a movable beam, which is fixedly connected to the output end of the variable pitch drive mechanism and extends along the second horizontal direction. Multiple adsorption mechanisms are slidably disposed on the movable beam.

[0043] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] like Figures 1-5As shown, this utility model provides a variable-pitch material distribution device for distributing products 100. The variable-pitch material distribution device includes a feeding device 1 and a distributing device 2. The feeding device 1 includes a collection trough 11, which is configured to accommodate product 100. In the first horizontal direction, one end of the collection trough 11 is a feeding end, and the other end is a distributing end. The distributing device 2 includes a variable-pitch trough plate 21, a variable-pitch drive mechanism 22, and multiple adsorption mechanisms 23. The variable-pitch trough plate 21 is mounted above the distributing end and is provided with multiple guide channels 210 spaced apart along the second horizontal direction. One end of the guide channel 210 is an adsorption end, and the other end is a variable-pitch end. The distance between any two adjacent variable-pitch ends is equal. The adsorption mechanism 23 is slidably disposed between the variable-pitch trough plate 21 and the bottom of the collection trough 11. The top of the adsorption mechanism 23 is provided with a guide member 231, which is located in the guide channel 210. Each adsorption mechanism 23 can adsorb one product 100 along the first horizontal direction. The variable-pitch drive mechanism 22 is configured to drive the guide member 231 to move from the adsorption end to the variable-pitch end. The first horizontal direction is perpendicular to the second horizontal direction.

[0045] When variable-pitch material distribution is required, each adsorption mechanism 23 can adsorb one product 100 along the first horizontal direction. The variable-pitch drive mechanism 22 is configured to drive the guide 231 to move from the adsorption end to the variable-pitch end, thereby driving the product 100 to change pitch. In other words, by adjusting the spacing of the variable-pitch end of each guide channel 210 on the variable-pitch groove plate 21, the spacing of the product 100 after variable-pitch material distribution can be adjusted. It is highly flexible, applicable to a variety of different working conditions, and has a high degree of automation, low manual intervention, and high work efficiency.

[0046] It is understandable that, depending on the different pitch distances between any two adjacent guide channels 210, the pitch trough plate 21 can be configured in various ways to suit a variety of different working conditions, and the two ends of the pitch trough plate 21 are detachably connected to the side wall of the collection trough 11 by bolt structure for easy replacement.

[0047] For example, in this embodiment, the adsorption mechanism 23 is specifically a pneumatic adsorption gripping mechanism commonly used in the art. It uses the negative pressure of gas to adsorb and move the product 100, resulting in minimal mechanical wear on the product 100 and a high yield rate. Its working principle and specific structure will not be described in detail. In other embodiments, the adsorption mechanism 23 can also be a mechanical gripper structure commonly used in the art.

[0048] For example, in this embodiment, the variable pitch drive mechanism 22 is a linear trolley structure disclosed in the art, and its working principle and specific structure will not be described in detail here.

[0049] For example, in this embodiment, the guide member 231 is specifically a bearing structure commonly used in the art. It can reduce friction by converting the sliding friction between the outer ring and the inner wall of the guide channel 210 into rolling friction through the relative rotation between its inner ring and outer ring.

[0050] Specifically, the height of the feeding end is higher than that of the distributing end. This arrangement allows the collecting trough 11 to be tilted, enabling the product 100 to slide from the feeding end to the distributing end under its own gravity.

[0051] Specifically, the variable-pitch material distribution equipment also includes a guiding device 3, which includes guide plates 31. Multiple guide plates 31 are spaced apart along the second horizontal direction, and any two adjacent guide plates 31 form a guiding channel. One end of each guiding channel faces the feeding end of the collecting trough 11, and the other end faces the adsorption mechanism 23. The multiple guiding channels correspond one-to-one with the multiple adsorption mechanisms 23. The arrangement of the guiding device 3 ensures that the guiding channels extend along the first horizontal direction, allowing the products 100 to abut against the guide plates 31 and be arranged along the first horizontal direction, preventing one adsorption mechanism 23 from simultaneously adsorbing multiple products 100, thus improving operational accuracy.

[0052] Specifically, the guiding device 3 further includes a material-feeding assembly 32, which includes a transmission rod 321, a material-feeding drive mechanism 323, and multiple material-feeding cranks 322. The transmission rod 321 is slidably inserted into the material collection trough 11 along a second horizontal direction; the multiple material-feeding cranks 322 are spaced apart on the transmission rod 321; when the material-feeding drive mechanism 323 drives the transmission rod 321 to reciprocate along the second horizontal direction, the material-feeding cranks 322 can actuate the products 100. With this configuration, the material-feeding cranks 322 can reciprocate along the second horizontal direction under the drive of the transmission rod 321, actuating the products 100, so that multiple products 100 arranged along the second horizontal direction can enter multiple guiding channels one-to-one.

[0053] More specifically, the feeding assembly 32 also includes an eccentric wheel 324, a connecting block 325, and a rocker arm 326. The eccentric wheel 324 is connected to the output end of the feeding drive mechanism 323 and has a guide hole extending radially from itself. Two transmission rods 321 are spaced apart in the first horizontal direction, and the two ends of the connecting block 325 are fixedly connected to the ends of the two transmission rods 321 respectively. One end of the rocker arm 326 is rotatably equipped with a transmission block 326a, which slides in the guide hole. The other end of the rocker arm 326 is rotatably connected to the connecting block 325. When the feeding drive mechanism 323 drives the eccentric wheel 324 to rotate around its center, the transmission block 326a reciprocates in the guide hole, and both transmission rods 321 reciprocate in the second horizontal direction under the drive of the connecting block 325. The above configuration, in which the eccentric wheel 324, connecting block 325 and rocker arm 326 cooperate with each other to convert the rotational output of the feeding drive mechanism 323 into the linear motion of the transmission rod 321, has high stability, low mechanical wear and good durability.

[0054] For example, in this embodiment, the feeding drive mechanism 323 is a rotary motor or motor commonly used in the art, and its working principle and specific structure will not be described in detail here.

[0055] Alternatively, in other embodiments, the eccentric wheel 324, connecting block 325, and rocker arm 326 may be omitted, and the feeding drive mechanism 323 may be adjusted to a reciprocating linear motor commonly used in the art. The output end of the feeding drive mechanism 323 is fixedly connected to the end of the transmission rod 321, thereby achieving the reciprocating motion of the transmission rod 321 while simplifying the structure.

[0056] More specifically, the multiple guide plates 31 can be divided into first guide plates 311 and second guide plates 312 according to their different lengths. The length of the first guide plate 311 is greater than the length of the second guide plate 312, and a second guide plate 312 is provided between any two adjacent first guide plates 311. The above arrangement can prevent two products 100 from getting stuck at the opening of the guide channel at the same time.

[0057] Preferably, in this embodiment, the product 100 is cylindrical. At one end near the dispensing device 2, the first guide plate 311 and the second guide plate 312 are aligned with each other. At the other end away from the dispensing device 2, the length difference between the first guide plate 311 and the second guide plate 312 is equal to the cross-sectional diameter of the product 100. This configuration allows the product 100 to slide around the first guide plate 311 and enter the guide channel if it becomes stuck at the opening of the guide channel.

[0058] Specifically, the material distribution device 2 also includes a movable beam 24, which is fixedly connected to the output end of the variable pitch drive mechanism 22 and extends along the second horizontal direction. Multiple adsorption mechanisms 23 are slidably mounted on the movable beam 24. When the movable beam 24 moves along the first horizontal direction under the drive of the variable pitch drive mechanism 22, the adsorption mechanisms 23 move along the movable beam 24. The aforementioned movable beam 24 allows multiple variable pitch drive mechanisms 22 to simultaneously move from the adsorption end to the variable pitch end of the guide channel 210, thereby ensuring the consistency of the actions of the multiple variable pitch drive mechanisms 22.

[0059] Specifically, the variable-pitch material distribution equipment also includes a capping device 4, which comprises a capping beam 41 and two capping drive mechanisms 42. The capping beam 41 extends along a first horizontal direction; the output ends of the two capping drive mechanisms 42 are connected to the two ends of the capping beam 41 respectively. The capping drive mechanisms 42 are configured to drive the capping beam 41 to move vertically. When the adsorption mechanism 23 adsorbs a row of products 100, the capping beam 41 can abut and lock against another row of products 100 adjacent in the first horizontal direction. The capping device 4 prevents multiple products 100 from being adsorbed by the same adsorption mechanism 23, improving operational stability.

[0060] Preferably, in this embodiment, the pressure beam 41 is provided with an anti-slip structure, which can be an anti-slip pad, such as a rubber pad; or, the anti-slip structure can be an anti-slip protrusion, which can be a dot-shaped protrusion or a textured protrusion of any shape, as long as it can increase the contact friction between its location and the top of the product 100. The specific form can be referred to the prior art, and no specific limitation is made in this embodiment.

[0061] Specifically, the feeding device 1 also includes two guide blocks 12, which are arranged opposite to each other in the collecting trough 11 and each has a guide surface. The two guide surfaces are close to each other in the direction near the distributing end. This arrangement allows the product 100 to gradually converge at the opening of the guide channel under the action of the guide surfaces.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
