Description

Technical Field

[0001] This utility model relates to the field of automated packaging technology, and in particular to a bottle cap feeding and conveying device. Background Technology

[0002] In recent years, an increasing number of high-end daily chemical products have adopted colorful bottle packaging, greatly enhancing the product's packaging grade and making it more popular. Most high-end daily chemical products also use pump caps for sealing, making them more convenient to use.

[0003] In automated packaging processes, the pump cap feeding and conveying process is inconvenient due to the irregular structure of the pump caps and their tubular construction, often relying on manual placement. Even with automated pump cap conveying systems, the process is mostly linear, resulting in low efficiency and difficulty in effectively separating stacked pump caps, requiring manual intervention. Such equipment suffers from low automation, low efficiency, and consumes significant human and financial resources, hindering business development. Utility Model Content

[0004] Purpose of the utility model: To address the problems existing in the prior art, this utility model provides a bottle cap feeding and conveying device. By designing a circulating conveyor belt, one side clamps and conveys the cap to the bottle cap transfer assembly, while the other side clamps and feeds the cap from the bottle cap transfer assembly through a feeding gripper assembly. The bottle cap transfer assembly can complete multiple tasks simultaneously and can be reused, greatly improving the degree of automation and efficiency.

[0005] Technical solution: This utility model provides a bottle cap feeding and conveying device, including at least one clamping and conveying component, a feeding gripper component, and a bottle cap transfer component disposed between the clamping and conveying component and the feeding gripper component;

[0006] The clamping and conveying assembly is used to clamp and convey the pump cap to the position of the bottle cap transfer assembly;

[0008] The feeding gripper assembly is used to clamp the pump cap on the bottle cap transfer assembly and complete the feeding.

[0009] Furthermore, the clamping and transmission assembly includes a pair of transmission chains arranged opposite each other, the distance between the pair of transmission chains being less than the diameter of the upper end of the pump cover and greater than the diameter of the pipe at the lower end of the pump cover, the pump cover being disposed between the pair of transmission chains, and a first driving member being disposed on the transmission chains.

[0010] Furthermore, the clamping and transferring components are provided in pairs, and the pair of clamping and transferring components are arranged in parallel and perpendicular to the bottle cap transferring components.

[0011] Furthermore, a left and right limiting rod and a height limiting rod are also provided above the pair of transmission chains. The distance between the left and right limiting rods matches the upper diameter of the pump cover. The height limiting rod is provided above the pump cover between the pair of transmission chains to limit the height of the pump cover.

[0012] Furthermore, a spacing adjustment component is also provided on the pair of transmission chains. The spacing adjustment component includes a connecting plate connected to the base of the pair of transmission chains. The connecting plate is rotatably connected to a first lead screw, which is connected to a handwheel. The two sides of the connecting plate are also slidably connected to a guide rail.

[0013] Furthermore, the circulating conveyor belt of the bottle cap transfer assembly is vertically arranged, and a vertical slide rail is also provided between the receiving seat and the circulating conveyor belt at intervals. The vertical slide rail is fixed on the circulating conveyor belt, and the receiving seat is slidably connected to the vertical slide rail.

[0014] Furthermore, fixed stops are provided at intervals on one side of the circulating conveyor belt facing the clamping and conveying assembly, and a notch is provided at the adjacent fixed stop facing the clamping and conveying assembly, the notch matching the size of the pump cover.

[0015] Furthermore, an adjustable stop bar is provided on one side of the circulating conveyor belt opposite the feeding gripper assembly. The adjustable stop bar can rotate at a certain angle relative to the circulating conveyor belt, moving closer to or further away from the receiving seat.

[0016] Furthermore, a telescopic cylinder is rotatably connected to the base of the circulating conveyor belt, and a connecting rod is rotatably connected to the actuating end of the telescopic cylinder. The connecting rod is connected to the adjustable stop rod through a rotating plate, and the rotating plate is hinged to the base of the circulating conveyor belt.

[0017] Furthermore, the circulating conveyor belt has an elliptical structure, and one of the arc-shaped regions of the ellipse is provided with a pump head direction adjustment channel. The width of the pump head direction adjustment channel is less than the length of the pump head of the pump cover and greater than the width of the pump head.

[0018] Furthermore, the feeding gripper assembly includes several pairs of gripping heads, which are driven by gripper cylinders.

[0019] Furthermore, the clamping and conveying component and the feeding gripper component are also disposed on the longitudinal sliding mechanism, the bottle cap transfer component is located directly above the longitudinal sliding mechanism, the clamping and conveying component and the feeding gripper component are respectively disposed at both ends of the longitudinal sliding mechanism, and the longitudinal sliding mechanism respectively drives the clamping and conveying component and the feeding gripper component to move towards or away from the bottle cap transfer component.

[0020] Beneficial effects

[0021] 1. This utility model incorporates a circulating conveyor belt in both the clamping and conveying assembly and the feeding gripper assembly. The circulating conveyor belt sequentially separates the pump caps from the clamping and conveying assembly and transports them to the feeding gripper assembly, where the feeding process is completed. After feeding, the circulating conveyor belt of the cap transfer assembly continues its circulation, and the receiving seat without pump caps moves to the clamping and conveying assembly for feeding. In other words, pump cap feeding, conveying, and delivery can be performed simultaneously, significantly improving work efficiency.

[0022] 2. This utility model uses a pair of transmission chains to transport the pump cap. The distance between the two first transmission lines is just enough to clamp the pump cap and move it forward with the transmission chain. Left and right limiting rods are set on the transmission chain to limit the left and right sides of the pump cap, keeping its position relatively fixed and facilitating the loading of the bottle cap transfer assembly. The height limiting rod is used to limit the height of the pump cap, preventing multiple pump caps from stacking during transport and affecting subsequent loading operations.

[0023] 3. A spacing adjustment component is set on the side of the transmission chain, which can adjust the spacing between a pair of transmission chains to adapt to different product pump cover sizes, making it more practical.

[0024] 4. This utility model is designed with a vertical circulating conveyor belt that forms an ellipse. The receiving seat is set on a vertical slide rail. The height of the entire receiving seat can be slightly adjusted by the slide rail, which facilitates docking with the clamping and conveying components and the feeding gripper components.

[0025] 5. This utility model features a fixed stop bar on the side of the circulating conveyor belt facing the clamping and conveying assembly. This stop bar serves to prevent the receiving seat from falling off after loading is complete. After loading, the receiving seat moves forward with the circulating conveyor belt, and the fixed stop bar prevents the pump cover from falling off during this movement. At the loading position, the notch between adjacent fixed stop bars is used for loading the pump cover.

[0026] 6. The purpose of the adjustable stop lever in this utility model is to provide a blocking effect when the pump cover is fed from the clamping and conveying assembly onto the circulating conveyor belt and moves to the position of the feeding gripper assembly under the drive of the circulating conveyor belt. When the feeding gripper assembly needs to clamp the pump cover for feeding, the adjustable stop lever can rotate at a certain angle away from the receiving seat without affecting the stroke of the feeding gripper assembly in clamping the pump cover.

[0027] 7. This utility model uses a telescopic cylinder to extend and retract to pull the connecting rod. After the connecting rod is pulled, the rotating plate rotates along the base of the circulating conveyor belt. In this way, the connecting rod drives the adjustable stop bar connected to it to rotate upward at a certain angle and move away from the receiving seat of the circulating conveyor belt.

[0028] 8. This utility model sets a pump head direction adjustment channel in the arc area. The width of the pump head direction adjustment channel is less than the length of the pump head of the pump cover and greater than the width of the pump head. In this way, when the pump cover enters the pump head direction adjustment channel, the pump nozzle of the pump cover faces one direction due to the obstruction of the channel, which makes it easier for the subsequent feeding gripper assembly to grab and feed the material.

[0029] 9. This utility model sets the clamping and transmission component and the feeding gripper component on the longitudinal sliding mechanism, which can move back and forth, facilitating feeding and delivery. Attached Figure Description

The bottle cap transfer assembly 200 includes a circulating conveyor belt 201, on which receiving seats 202 are provided at intervals. The outer side of the receiving seat 202 is provided with an arc-shaped notch 214 that matches the pump cap 500, and the bottom of the notch 214 is provided with an arc-shaped groove bottom 215.

[0046] The feeding gripper assembly 300 is used to clamp the pump cap 500 on the bottle cap transfer assembly 200 and complete the feeding.

[0047] The clamping and conveying assembly 100 and the feeding gripper assembly 300 are also mounted on the longitudinal sliding mechanism 400.

[0050] A left and right limiting rod 103 and a height limiting rod 104 are also provided above the pair of transmission chains. The distance between the left and right limiting rods 103 matches the upper diameter of the pump cover 500. The height limiting rod 104 is provided above the pump cover 500 between the pair of transmission chains 101 to limit the height of the pump cover 500.

[0051] A spacing adjustment assembly is also provided on the pair of transmission chains 101. The spacing adjustment assembly includes a connecting plate 105 connected to the base of the pair of transmission chains 101. The lower end of the connecting plate 105 is rotatably connected to a first lead screw 106, which is connected to a handwheel 107. The lower ends of the connecting plate 105 are also slidably connected to guide rails 108 on both sides. By rotating the first lead screw 106, the connecting plate 105 is moved left and right, thereby adjusting the spacing of the entire transmission chain 101.

[0052] The circulating conveyor belt 201 of the bottle cap transfer assembly 200 is vertically arranged, see [reference]. Figures 4-6 A vertical slide rail 203 is also provided between the receiving seat 202 and the circulating conveyor belt 201.

[0053] Fixed stops 204 are also provided at intervals on one side of the circulating conveyor belt 201 facing the clamping and transmission assembly 100. A notch 205 is provided between the adjacent fixed stops 204 facing the clamping and transmission assembly 100. The notch 205 matches the size of the pump cover 500.

[0054] An adjustable stop bar 206 is provided on one side of the circulating conveyor belt 201 facing the feeding gripper assembly 300. The adjustable stop bar 206 is equipped with a rotary drive assembly, which can rotate relative to the circulating conveyor belt 201 at a certain angle, moving closer to or further away from the receiving seat 202. The rotary drive assembly includes a telescopic cylinder 207 rotatably connected to the base of the circulating conveyor belt 201. A connecting rod 208 is rotatably connected to the actuating end of the telescopic cylinder 207. The connecting rod 208 is connected to the adjustable stop bar 206 through a rotating plate 209, and the rotating plate 209 is hinged to the base of the circulating conveyor belt 201.

[0055] The circulating conveyor belt 201 has an elliptical structure. One of the arc-shaped areas of the ellipse is also provided with a pump head direction adjustment channel 210. The width of the pump head direction adjustment channel 210 is less than the length of the pump head of the pump cover 500 but greater than the width of the pump head.

[0056] An annular baffle 213 is connected to the two arc-shaped areas on both sides of the ellipse by a T-shaped bracket 212. The annular baffle 213 is adjacent to the adjustable baffle 206 and the fixed baffle 204.

[0057] The feeding gripper assembly 300 includes several pairs of gripping heads 301, which are driven by gripper cylinders 302.

[0058] Working principle:

[0059] Pump covers 500 are placed sequentially between conveyor chains 101. As the conveyor chains 101 transmit, the pump covers 500 move closer to the bottle cap transfer assembly 200. After approaching the bottle cap transfer assembly 200, the circulating conveyor line 201 operates, causing the receiving seat 202 to move in a ring. When the receiving seat 202 moves to the end of the conveyor chain 101, the conveyor chain 101 moves the pump covers 500 into the receiving seat 202. The circulating conveyor line 201 moves the receiving seat 202 and the pump covers 500 inside it towards the pump head direction adjustment channel 210. Under the action of the pump head direction adjustment channel 210, the pump head direction is adjusted. When the pump covers 500 move to face the feeding gripper assembly 300, the telescopic cylinder 207 is activated, flipping the adjustable stop bar 206 upward. The gripping head 301 approaches the receiving seat 202, and the gripper cylinder 302 drives the gripping head 301 to grip the pump covers 500 to complete the feeding operation.

They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
