Description

Technical Field

[0001] The utility model relates to the field of transportation, in particular to a conveying clamp and a conveying device. Background Art

[0002] For the transportation of bottled products, the existing solutions all use a method of using a gripper to grab the items to be transported. This method requires the setting up of a complex grabbing mechanism, which generally uses a cylinder to control the opening and closing of the gripper for grabbing. In this way, each gripper needs to add a drive device, and a production line will operate dozens or hundreds of items to be transported at the same time, which requires a large number of drives, adding a great burden to daily maintenance.

[0003] Therefore, we designed a conveying device such as the Chinese patent publication number CN114538082A entitled "A Bottled Product Conveying Device", which uses a flexible electric drive transmission rail to control multiple transport vehicles. A claw is installed on each transport vehicle. The two claws form a pair and are used to clamp the items to be transported for transportation. The opening and closing of the claws are uniformly controlled by the flexible electric drive transmission rail. The control accuracy is high, which greatly reduces the difficulty of maintenance. In addition, the entire conveying device has a simple structure. There are no bending or rotating parts when grabbing the bottle body, which greatly reduces the difficulty of processing and manufacturing, and has a long service life and high reliability.

[0004] However, the above design requires a transport vehicle for each clamping claw, which places higher requirements on the number of transport vehicles. In addition, the price of transport vehicles is currently not low, resulting in excessively high costs for the conveying device. In addition, the synchronization state of the two transport vehicles needs to be precisely controlled when clamping, transporting, and releasing the items to be transported, which also increases the difficulty of the control technology. Utility Model Content

[0005] The utility model aims to provide a conveying clamp and a conveying device, which can effectively solve the problem that the existing conveying device uses two transport vehicles for cooperation in transportation, has high control difficulty and high production cost.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] A conveying clamp comprises a base and a pair of claws, wherein the base is provided with a driving mechanism for driving the pair of claws to move in opposite directions, and the driving mechanism comprises a first moving component and a second moving component, wherein the first moving component is slidably arranged on the base and an end portion extends out of the base, and the second moving component is slidably arranged on the base, and the sliding direction of the second moving component is the same as the moving direction of the conveying clamp, the pair of claws are arranged on the second moving component, and the first moving component is transmission-connected to the second moving component via a transmission component.

[0008] In the above-mentioned conveying clamp, the first moving assembly includes at least one first sliding rod, at least one end of the first sliding rod extends out of the base, and the first sliding rod is connected to the transmission assembly.

[0009] In the above-mentioned conveying clamp, there are two first sliding bars, which extend out of the base from opposite ends of the base respectively. The two first sliding bars are respectively located on both sides of the transmission component and mesh with the transmission component for transmission.

[0010] In the above-mentioned conveying clamp, the first moving assembly also includes two auxiliary sliding bars, the two auxiliary sliding bars and the two first sliding bars are arranged in parallel, one auxiliary sliding bar corresponds to one first sliding bar and both ends are connected by a connecting plate.

[0011] In the above-mentioned conveying clamp, two claws are slidably arranged at the front end and the rear end of the conveying clamp respectively, and the second moving component includes two second sliding bars arranged in parallel, and the two second sliding bars are both slidably arranged on the base, each of the second sliding bars is fixedly connected to a claw, and the two second sliding bars are both transmission-connected to the transmission component.

[0012] In the above-mentioned conveying clamp, the two second sliding rods are both meshed with the teeth of the transmission assembly.

[0013] In the above-mentioned conveying clamp, a positioning block is also provided on the base between the pair of clamping claws, which is used to extend into the bottom of the object to be transported for positioning.

[0014] In the above-mentioned conveying clamp, an elastic return member is also provided between the pair of clamping claws.

[0015] Also disclosed is a conveying device using a conveying clamp according to any of the above-mentioned schemes, comprising a frame and a linear motor arranged on the frame, each mover of the linear motor is provided with a group of conveying clamps, the frame is wound into a ring, the frame includes a straight line segment, and the frame of the straight line segment is provided with a driving component for driving the first moving component to move.

[0016] In the above-mentioned conveying device, the driving assembly includes a guide block, which is located on the side of the running direction of the conveying clamp, and the minimum distance between the guide block and the base is less than the length of the first moving assembly extending from the base.

[0017] Compared with the prior art, the advantages of the utility model are:

[0018] A pair of claws is arranged on the base, and a driving device for driving the pair of claws to move in the opposite direction is also arranged on the base, which solves the problem that a claw is required to be arranged on each of the two movers for transportation, which is difficult to control and has high production costs. The first moving component with the end extending out of the base can touch the outside world to drive the first moving component to move, and the movement power drives the second moving component to move through a transmission mode, thereby controlling the opening and closing of a pair of claws arranged on the second moving component, thereby achieving the purpose of transporting the items to be transported by arranging a pair of claws on a base. Through the above arrangement, the two claws are on the same base, so the number of movers occupied by them will be reduced by half, which greatly saves the manufacturing cost of the entire conveyor line, and because the two claws are driven to open and close by the second moving component, and the second moving component is driven by the first moving component, the first moving component has an end extending out of the base, therefore, as long as the end of the first moving component extending out of the base is touched, the movement of the first moving component can be controlled, so that the difficulty of controlling the opening and closing of the claws is reduced.

[0019] Furthermore, the first moving assembly includes at least one first sliding rod, at least one end of which extends out of the base, and the first sliding rod is connected to the transmission assembly. When the end of the first sliding rod extending out of the base is touched, power can be transmitted to the transmission assembly, thereby driving the second moving assembly to move.

[0020] Furthermore, there are two first slide bars, which extend from opposite ends of the base, respectively, and the two first slide bars are located on both sides of the transmission assembly, and mesh with the transmission assembly for transmission. The two first slide bars extend from opposite ends of the base, and the first slide bars can be triggered to move from more angles, thereby providing more possibilities for controlling the movement of the first slide bars, and both first slide bars are meshed with the transmission assembly for transmission, that is, no matter which first slide bar is triggered, it will drive the transmission assembly to move.

[0021] Furthermore, the first moving assembly further comprises two auxiliary sliding bars, the two auxiliary sliding bars and the two first sliding bars are arranged in parallel, one auxiliary sliding bar corresponds to one first sliding bar and both ends are connected by connecting plates. One first sliding bar is connected to one auxiliary bar by a connecting plate, and when the first sliding bar is acted upon by an external force, the sliding can be more stable, ensuring that the sliding track of the first sliding bar is stable, thereby driving the transmission assembly to rotate more smoothly.

[0022] Furthermore, two claws are respectively slidably arranged at the front end and the rear end of the conveying clamp, and the second moving assembly includes two second sliding bars arranged in parallel, and the two second sliding bars are both slidably arranged on the base, each second sliding bar is respectively fixedly connected to a claw, and the two second sliding bars are both transmission-connected to the transmission assembly. The opening and closing of the two claws are controlled by the two second sliding bars sliding relatively, and the two claws are arranged front and back, which makes it more convenient to load and unload the transported items from the side and avoids interference with the front and rear conveying clamps.

[0023] Furthermore, the two second slide bars are meshed with the teeth of the transmission assembly. The transmission assembly can simultaneously drive the two second slide bars to move, thereby controlling the two claws to open and close synchronously, making it easier to achieve the positioning of the clamped items to be transported.

[0024] Furthermore, a positioning block is provided on the base between the pair of claws, which is used to extend into the bottom of the object to be transported for positioning. The positioning block is used to position and fix the bottom of the object to be transported after the object to be transported is placed, so that the manipulator can more accurately grasp the object to be transported when unloading the object to be transported.

[0025] Furthermore, an elastic return member is provided between the pair of claws, which can return the pair of claws, the first moving assembly and the second moving assembly to their initial positions after the first slide bar removes the external force, so that the claws can move again when the first slide bar is touched by the external force next time.

[0026] Also disclosed is a conveying device using a conveying clamp of any of the above schemes, comprising a frame and a linear motor arranged on the frame, each mover of the linear motor is provided with a group of conveying clamps, the frame is wound into a ring, the frame includes a straight section, and the frame of the straight section is provided with a driving assembly for driving the first moving assembly to move. In the conveying device using any of the above schemes, a conveying clamp is arranged on a mover to achieve the clamping of an object to be transported, and a driving assembly is arranged on the straight section, and the first moving assembly is triggered to move by the driving assembly, thereby controlling the opening and closing of a pair of claws. The control method is simple and easy to implement, and does not increase excessive manufacturing costs. The driving assembly is arranged on the straight section of the frame, and the degree of opening of the claws can be more accurately controlled, so that the object to be transported can be better placed between the pair of claws.

[0027] Furthermore, the driving assembly includes a guide block, the guide block is located on the side of the running direction of the conveying clamp, and the minimum distance between the guide block and the base is less than the length of the first movable assembly extending from the base. The end of the first movable assembly extending from the base is abutted against the guide block, and the guide block will push the first movable assembly to move, thereby realizing the control of the opening of a pair of claws. This control method is efficient and not prone to error, and can accurately achieve the purpose of controlling the opening of the claws. In addition, by adjusting the position of the guide block and the end of the first movable assembly, the degree of opening of the claws can also be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The first moving assembly 300, whose end extends out of the base 100, can touch the outside world to drive the first moving assembly 300 to move, and the movement power drives the second moving assembly 400 to move through the transmission mode, so as to control the opening and closing of a pair of claws 200 set on the second moving assembly 400, thereby achieving the purpose of transporting the items to be transported by setting a pair of claws 200 on a base 100. Through the above arrangement, the two claws 200 are on the same base 100, so the number of movers 800 occupied by them will be reduced by half, which greatly saves the manufacturing cost of the entire conveyor line, and because the two claws 200 are driven to open and close by the second moving assembly 400, and the second moving assembly 400 is driven by the first moving assembly 300, the first moving assembly 300 has an end extending out of the base 100, therefore, as long as the end of the first moving assembly 300 extending out of the base 100 is touched, the movement of the first moving assembly 300 can be controlled, so that the difficulty of controlling the opening and closing of the claws 200 is reduced.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] See also Figures 1 to 8This is an embodiment of a conveying clamp of the utility model, a conveying clamp, comprising a base 100 and a pair of claws 200, the claws 200 are arranged front and back on the base 100 along the movement direction of the base 100, and a driving mechanism for driving the pair of claws 200 to move in the opposite direction is provided on the base 100, that is, the driving mechanism drives the claws 200 to close or separate. The driving mechanism comprises a first moving assembly 300 and a second moving assembly 400, the first moving assembly 300 is slidably arranged on the base 100 and the end thereof extends out of the base 100, the first moving base 100 is mainly used for contacting with an external connection, and the first moving assembly 300 is pushed to slide on the base 100 by the external force, so as to receive the driving force from the outside; the second moving assembly 400 is slidably arranged on the base 100, the sliding direction of the second moving assembly 400 is the same as the moving direction of the conveying clamp, that is, the second moving assembly 400 also slides back and forth, and the second moving assembly 400 is mainly used for driving the pair of claws 200 to move in the opposite direction. The first moving assembly 300 and the second moving assembly 400 are connected by transmission assembly 500, so that when the first moving assembly 300 slides due to external force, the power is transmitted to the second moving assembly 400 through the transmission assembly 500, so that the second moving assembly 400 slides, thereby driving the pair of claws 200 to move in the opposite direction. Through the above structure, the pair of claws 200 can be set on the same base 100 and installed on the transport vehicle, thereby avoiding the problem of setting the pair of claws 200 separately and occupying two transport vehicles in the past, greatly saving the number of transport vehicles, reducing the cost of the entire conveying device, and also making the conveying device structure more compact.

[0054] Furthermore, the first moving assembly 300 includes at least one first sliding rod 310, at least one end of the first sliding rod 310 extends out of the base 100, the first sliding rod 310 is connected to the transmission assembly 500, the number of the first sliding rod 310 can be set according to the need of external triggering, and at least one end of the first sliding rod 310 extends out of the base 100, and the extended part is used to contact with the external connection, and slides after receiving the transmission of external force. In order to control the sliding path of the first sliding rod 310 when it is subjected to external force, a slide groove can be opened on the base 100, and the first sliding rod 310 is set in the slide groove.

[0055] In this embodiment, there are two first slide bars 310, and they extend out of the base 100 from opposite ends of the base 100, so that the two first slide bars 310 can be pushed to move simultaneously by receiving forces from both sides, or when one first slide bar 310 is pushed, it can also drive the transmission assembly 500 to move and transmit the force to the second moving assembly 400. In order to achieve the above purpose, the two first slide bars 310 are respectively arranged on both sides of the transmission assembly 500, so that the sliding of the two first slide bars 310 will not cause interference, and the first slide bars 310 can drive the transmission assembly 500 to rotate by friction, or adopt a meshing form similar to a gear rack, and drive the transmission assembly 500 to rotate by sliding the first slide bars 310. In this embodiment, a gear rack transmission is adopted, and the rack is arranged on the first slide bar 310, and the transmission assembly 500 includes a gear rotatably arranged on the base 100. In this way, as long as any one of the first slide bars 310 slides under the action of external force, it can drive the transmission assembly 500 to rotate.

[0056] like Figure 3 , Figure 5 As shown, further, the first moving assembly 300 also includes two auxiliary sliding rods 320, which are arranged in parallel with the two first sliding rods 310. One auxiliary sliding rod 320 corresponds to one first sliding rod 310 and both ends are connected by a connecting plate 330. In this way, both ends of the two auxiliary sliding rods 320 and the two first sliding rods 310 extend out of the base 100. Figure 3 As shown, along the forward direction, there are respectively the first auxiliary sliding bar 320, the first first sliding bar 310, the second first sliding bar 310 and the second auxiliary sliding bar 320. The two ends of the first auxiliary sliding bar 320 are connected to the two ends of the second auxiliary sliding bar 320 through the connecting plate 330, and the two ends of the second auxiliary sliding bar 320 are connected to the two ends of the first auxiliary sliding bar 320 through the connecting plate 330. The left end of the first first sliding bar 310 is farther away from the base 100 than the left end of the second first sliding bar 310, and the right end of the second first sliding bar 310 is farther away from the base 100 than the right end of the first first sliding bar 310. Therefore, the left end of the first first sliding bar 310 and the left end of the second auxiliary sliding bar 320 will pass through the connecting plate 330 on the left side of the first auxiliary sliding bar 320 and the second first sliding bar 310; the right side is distributed similarly to the left side, and the second first sliding bar 310 will be farther away from the base 100 than the right side of the first first sliding bar 310. This arrangement allows the two connecting plates 330 on the left or the two connecting plates 330 on the right to abut against each other after the first slide bar 310 slides under force, thereby limiting the movement range of the first slide bar 310 .

[0057] like Figure 4 , Figure 6As shown, the second moving component 400 in this embodiment includes two second sliding bars 410 arranged in parallel, and the transmission component 500 is located between the two parallel second sliding bars 410. The two second sliding bars 410 and the transmission component 500 can be transmitted by friction or meshing. In this embodiment, meshing transmission will be adopted, and a rack is set on the second sliding bar 410. The transmission component 500 is a gear. Since the transmission component 500 also needs to mesh with the first sliding bar 310, the gear of the transmission component 500 can be set at the center position of the base 100 and the length can be lengthened to be able to mesh with the first sliding bar 310 and the second sliding bar 410 at the same time. The second sliding bar 410 will be located above the first sliding bar 310, that is, the first sliding bar 310 and the second sliding bar 410 are stacked up and down.

[0058] Two slide bars 420 parallel to the second slide bar 410 are also provided on the base 100, and matching sliders 430 are provided at both ends of each slide bar 420. One claw 200 is fixedly connected to the two sliders 430 at the front end of the base 100, and the other claw 200 is fixedly connected to the two sliders 430 at the rear end of the base 100. One claw 200 is fixedly connected to one second slide bar 410, and the other claw 200 is fixedly connected to another second slide bar 410. When the transmission assembly 500 rotates, the two second slide bars 410 can be driven to slide synchronously, so that the two claws 200 move synchronously toward or in opposite directions.

[0059] A positioning block 600 is also provided on the base 100 for positioning the bottom of the item to be transported. The item to be transported is generally a plastic bottle or a glass bottle, and the bottom surface of the bottle generally protrudes toward the inside of the bottle. Therefore, the positioning block 600 can also be made into a convex block. The item to be transported is then placed on the base 100 to position the item to be transported and ensure that it is located between the two claws 200 to avoid pushing the item to be transported when the claws 200 clamp the item to be transported.

[0060] In addition, it is relatively easy to push the first moving assembly 300 to move, but it is relatively difficult to pull the first moving assembly 300 back to its original position. Therefore, an elastic return member 700 can be provided between a stack of claws 200. The elastic return member 700 generally adopts a tension spring. When the first moving assembly 300 slides under external force, the pair of claws 200 are separated. After the external force is removed, the elastic return member 700 can be used to allow the pair of claws 200 to close and clamp the object to be transported.

[0061] like Fig. 9As shown, the utility model also discloses a conveying device using a conveying fixture of any of the above schemes, including a frame and a linear motor mounted on the frame, and a set of conveying fixtures is fixed on each mover 800 of the linear motor, that is, the base 100 is fixed on the top of the mover 800. The frame is wound into a ring shape, and can circulate and transport items. The linear motor is arranged along the frame, and the frame includes a straight section. The frame located in the straight section is provided with a driving component for driving the first moving component 300 to slide. The driving component is mainly used to trigger the movement of the first moving component 300, so that a pair of claws 200 are opened, which is convenient for putting in or taking out the items to be transported. By arranging the driving component in the straight section of the frame, it is more convenient to arrange other corresponding components to grab and transport items.

[0062] The specific driving assembly includes a guide block 900, which is located on the side of the running direction of the transport clamp so that it can better contact the end of the first slide bar 310 protruding from the base 100. The minimum distance between the guide block 900 and the base 100 is less than the length of the first moving assembly 300 extending from the base 100. The first moving assembly 300 is caused to slide by the extrusion of the end of the first moving assembly 300 and the guide block 900. In this embodiment, guide blocks 900 are provided on both sides of the forward direction of the transport clamp. The guide blocks 900 are provided with inclined surfaces. After the first slide bar 310 contacts the inclined surfaces, as the mover 800 moves forward, the distance between the guide block 900 and the base 100 gradually decreases, so that the first slide bar 310 slides slowly and the claw 200 opens slowly. In addition to the guiding function, the inclined surfaces on the guide blocks 900 can also prevent the first slide bar 310 from vibrating the transported items due to sudden movement, and prevent the liquid in the transported items from spilling out.

[0063] like Figures 7 to 9As shown, when the mover 800 moves to the position of the guide block 900, the end of the first slide bar 310 protruding from the base 100 contacts the guide surface 910 of the guide block 900. As the mover 800 moves, the first slide bar 310 is pushed into the base 100. The sliding of the first slide bar 310 will drive the transmission assembly 500 to rotate. After the transmission assembly 500 rotates, it will drive the second slide bar 410 to slide. The second slide bar 410 drives a pair of claws 200 to move in the opposite direction, thereby pulling apart the spacing between a pile of claws 200, so that there is enough space to put the items to be transported therein. As a pile of claws 200 move in the opposite direction, the elastic return member 700 will also accumulate elastic potential energy. The items to be transported are placed on the base 100 using a mechanical arm and other components, and the bottom of the items to be transported cooperates with the positioning block 600 to determine the relative position of the items to be transported on the base 100. As the mover 800 continues to move out of the area of ​​the guide block 900, the guide block 900 loses its function, and the elastic potential energy of the elastic return member 700 is released, driving the pair of claws 200 to move toward each other to clamp the transported items, and at the same time driving the second slide bar 410 to slide, and the second slide bar 410 drives the transmission assembly 500 to rotate, so that the first slide bar 310 also slides, and the outer end of the first slide bar 310 moves in a direction away from the base 100 and returns to the initial state. If the transported items need to be unloaded, the drive assembly can be arranged on the frame to open the claws 200 to take out the transported items.

[0064] The conveying clamp and transportation device using the above-mentioned scheme can set a group of clamps on one mover 800. Compared with the previous method of setting one claw 200 on each mover 800, the number of movers 800 is reduced by half, so that the cost of the entire transportation device is greatly reduced, and there is no need to control the position of each mover 800 too precisely. When the claw 200 opens and closes, it is sufficient for the adjacent movers 800 to have a rough extension and retraction distance, without the need to precisely control the distance between the two movers 800 as in the past. This greatly reduces the control difficulty and improves the reliability of the conveying clamp.

[0065] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
