Description

Technical Field

[0001] The utility model relates to the technical field of bottle cap production, in particular to a pre-gripping positioning device for bottle cap production. Background Art

[0002] In the production process of container closures such as bottle caps or cup lids, gripping devices such as suction cups are required to grip and move them to the next process or stack them, etc. However, since the spacing between adjacent cup lids on the conveying mechanism may be inconsistent during production, and when the subsequent suction cup performs adsorption and gripping, it may not be able to accurately align with the cup lid. Therefore, generally, the distance between each cup lid is limited before adsorption and gripping.

[0003] Currently, when limiting the position of cup lids, it is common to perform positioning through the intermittent expansion and contraction of telescopic rods. Generally, a row of telescopic rods can only limit a row of cup lids on the conveying mechanism. And if it is necessary to improve production efficiency and there are multiple rows of cup lids conveyed on the conveying mechanism, multiple groups of telescopic rods need to be set to perform intermittent actions, which is rather troublesome.

[0004] Based on the above situation, we propose a pre-gripping positioning device for bottle cap production to solve the above problems. Content of the Utility Model

[0005] The utility model provides a pre-gripping positioning device for bottle cap production to solve the problem in the prior art that multiple groups of telescopic rods need to be set to limit multiple groups of cup lids during the conveying process, which is rather troublesome.

[0006] The technical problems solved by the utility model are realized by adopting the following technical solutions:

[0007] A pre-gripping positioning device for bottle cap production includes a conveying mechanism for conveying bottle caps, an equidistant separation component, and an equidistant feeding component. The equidistant separation component is used to linearly arrange the bottle cap products conveyed on the conveying mechanism. The equidistant separation component includes an installation frame and a plurality of arranging plates arranged between the installation frames. A conveying channel for the cup lid products to pass through is formed between two adjacent arranging plates. The equidistant feeding component is arranged above the equidistant separation component and is used to achieve equidistant feeding of the linearly arranged bottle cap products. The equidistant feeding component includes a transmission mechanism and two groups of baffle plates that move in opposite directions up and down through the transmission mechanism. And a baffle rod corresponding to the conveying channel is arranged below both groups of baffle plates.

[0008] Preferably, a lifting frame is connected to the transmission mechanism. A plurality of first installation slots are formed on the lifting frame. The baffle plate is detachably installed inside the first installation slot through a locking component. And a second installation slot is formed on the installation frame. The arranging plate is detachably connected to the inside of the second installation slot through the locking component.

[0009] Preferably, the locking assembly includes a locking rod rotatably connected to the material baffle and the arranging plate, and locking holes threadedly connected to the locking rod are formed in both the first installation groove and the second installation groove.

[0010] Preferably, the transmission mechanism includes a driving motor, a rotating gear provided at the output end of the driving motor, and a sliding rack meshing with the rotating gear. The lower end of the sliding rack is connected to the lifting frame. A connecting frame is provided on the conveying mechanism, and the driving motor is installed inside the connecting frame.

[0011] Preferably, a guide rod is provided at the upper end of the lifting frame. The guide rod penetrates through the connecting frame and is slidably connected to the connecting frame.

[0012] Preferably, the material baffle rod is movably connected below the material baffle.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. First, the bottle caps entering the conveying channel are linearly arranged so that the distance between each column of bottle cap products is equal. Then, under the action of the equidistant feeding component, the bottle cap products in each column of the conveying channel are intermittently and equidistantly conveyed, realizing the positioning of the bottle caps conveyed on the conveying mechanism, making the distance between adjacent two bottle cap products correspond to the subsequent adsorption and grasping device, so as to accurately grasp.

[0015] 2. By adjusting the distance between two adjacent arranging plates and two material baffles, it is adapted to position and convey bottle cap products of different diameters, and the adaptation range is wider. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0026] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific illustrations.

[0027] Refer to Figure 1 As shown, it is a schematic structural diagram of the prior art provided by the present utility model, including multiple groups of telescopic rods 7 arranged on the conveying mechanism 1. The bottle caps are equally spaced and positioned through the intermittent flexion and extension movements of the telescopic rods 7. If there are multiple suction cups both horizontally and vertically on the subsequent adsorption and grasping mechanism, that is, when they are arranged in a rectangular array, multiple groups of telescopic rods 7 are required, which increases the cost and is not convenient for flexible adjustment for cup lids of different diameters. Therefore, we make the following improvements to solve the above problems.

[0028] Specifically, refer to Figures 2 - 8As shown in the figure, a pre-gripping positioning device for cap production includes a conveying mechanism 1 for conveying caps, which can be a conveyor belt, etc. When caps are conveyed by the conveyor belt after production, many products may be randomly arranged on the conveying mechanism 1. An equidistant separation component is also provided on the conveying mechanism 1, which is used to linearly arrange the cap products conveyed on the conveying mechanism 1. The equidistant separation component includes a mounting frame 2 and a plurality of arranging plates 21 provided between the mounting frames 2. A conveying channel 22 for the passage of cup lid products is formed between two adjacent arranging plates 21. The cap products on the conveying mechanism 1 are separated and respectively enter a plurality of conveying channels 22. The width of the conveying channel 22 corresponds to the diameter of the cap. Therefore, the caps in the same conveying channel 22 are on the same straight line, and the distance between the caps in two adjacent conveying channels 22 is the same. Figure 7 For example, at this time, the distance between caps during horizontal or vertical adjacent transmission can be determined. Specifically, it can be determined horizontally or vertically according to the horizontal or vertical setting of the conveying channel 22;

[0029] An equidistant feeding component is also provided above the equidistant separation component, which is used to achieve equidistant feeding of linearly arranged cap products. The equidistant feeding component includes a transmission mechanism 3 and two groups of baffle plates 4 that move in opposite directions up and down through the transmission mechanism 3. And a baffle rod 41 corresponding to the conveying channel 22 is provided below both groups of baffle plates 4. The first cap product that first enters the front end of the conveying channel 22 will be blocked by the descending baffle rod 41 and cannot continue to be conveyed. When conveying is required, the baffle plate 4 located below is driven by the transmission mechanism 3 to move upward. At this time, the first cap product is unblocked by the upward movement of the baffle rod 41, and the cap is conveyed under the action of the conveying mechanism 1. And the baffle plate that was originally located above will move downward and block the front end of the second cap product in the conveying channel 22 to prevent the second cap from being conveyed synchronously with the first cap. When the transmission mechanism 3 acts again, the cap originally in the second position will move to the first position and wait for discharging. Since the conveying speed of the conveying mechanism 1 is constant, only the running speed of the transmission mechanism 3 needs to be changed. For example, after waiting for 2 s for the cap at the first position to be conveyed out, at this time the distance between the cap and the baffle plate 4 is 20 cm, and then the subsequent caps are conveyed. In this way, the caps in each conveying channel 22 are output at equal intervals, which is convenient for the accurate gripping of the subsequent adsorption and gripping device.

[0030] Refer to Figures 4 - 6As shown in the figure, further, a lifting frame 42 is connected to the transmission mechanism 3. A plurality of first mounting grooves 43 are formed in the lifting frame 42. The baffle plate 4 is detachably mounted inside the first mounting groove 43 through a locking assembly. And a second mounting groove 23 is formed in the mounting frame 2. The arranging plate 21 is detachably connected to the inside of the second mounting groove 23 through a locking assembly. According to the bottle cap products with different diameters, the width of the conveying channel 22 and the width between the two baffle plates 4 are adjusted. The number of arranging plates 21 on the mounting frame 2 can be increased or decreased, or the position of the baffle plate 4 in the first mounting groove 43 can be changed to change the spacing. For example, if the product diameter is large, the spacing between adjacent arranging plates 21 and between the two baffle plates 4 can be increased so that the product can enter the conveying channel 22.

[0031] Among them, in order to better install the baffle plate 4 and the arranging plate 21 stably, the locking assembly includes a locking rod 5 rotatably connected to the baffle plate 4 and the arranging plate 21. And locking holes 51 threadedly connected to the locking rod 5 are formed in both the first mounting groove 43 and the second mounting groove 23. After the installation of the baffle plate 4 or the arranging plate 21 is completed, the locking rod 5 is rotated into the locking hole 51.

[0032] Refer to Figure 4 As shown in the figure, further, the transmission mechanism 3 includes a driving motor 31, a rotating gear 32 provided at the output end of the driving motor 31, and a sliding rack 33 engaged with the rotating gear 32. The lower end of the sliding rack 33 is connected to the lifting frame 42. A connecting frame 34 is provided on the conveying mechanism 1. The driving motor 31 is installed inside the connecting frame 34. And the sliding rack 33 is slidably connected to the connecting frame 34. By driving the rotation of the rotating gear 32 by the driving motor 31, the two sliding racks 33 drive the two lifting frames 42 to move in opposite directions, one rising and one falling.

[0033] Among them, in order to make the lifting frame 42 drive the baffle plate 4 to move more stably, a guide rod 6 is provided at the upper end of the lifting frame 42. The guide rod 6 penetrates through the connecting frame 34 and is slidably connected to the connecting frame 34. The lifting movement of the lifting frame 42 is guided by the guide rod 6 to keep it moving stably vertically, so that the baffle plate 4 can more accurately block the bottle cap products in the conveying channel 22.

[0034] Further, the baffle rod 41 is movably connected to the lower part of the baffle plate 4, and the movable connection method is not limited. It can be threadedly connected to the baffle plate 4, or it can be snap-connected or a friction plate is provided at the end of the baffle rod 41. When the external force applied to the baffle rod 41 is greater than the friction force between the baffle rod 41 and the baffle plate 4, the baffle rod 41 can be moved, so as to adjust the distance between two adjacent baffle rods 41 when the width of the conveying channel 22 changes, facilitating the interception of bottle caps with different diameters. Refer to Figure 8 As shown, when the baffle plate 4 moves downward, the baffle rod 41 intercepts and blocks the bottle cap in the blank area between the cup lid product and the arranging plate 21.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
