Description

Technical Field

[0001] The present invention belongs to the technical field of dispensing devices, and particularly relates to an automatic dispensing device. Background Art

[0002] Most of the items sold on the market are accompanied by relevant label instructions, aiming to assist consumers in understanding the usage methods, manufacturing materials, etc. of the items themselves. For large-scale devices and equipment, most are accompanied by instruction manuals. For small items, such as component products, daily-use products, etc., most are directly attached with labels for explanation. In the subsequent use process, for the sake of beauty or convenience, consumers usually remove or tear off the labels attached to the surface of small items; the labels of small items are generally divided into tying types and pasting types. For items with holes or relevant grooves, the method of tying labels is usually selected, while for some items that cannot be tied with labels, the method of pasting is usually used to attach labels.

[0003] The labels tied to the items are easy to remove, but the labels adhered to the items are not easy to remove, and usually traces are easily left on the surface of the items after removal, affecting the aesthetics and usage effects.

[0004] Researchers found that for some items with smooth surfaces, hot melt glue can be used to adhere labels. When the label is to be torn off later, pulling the label forcefully can tear off the label; however, when attaching labels currently, it is all manual operation of hot melt glue, and the dispensing position cannot be kept consistent, affecting the final attaching effect of the label, and moreover, the production efficiency is low. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides an automatic dispensing device.

[0006] The present invention is implemented as follows:

[0007] An automatic dispensing device includes a label storage structure, a label distribution structure, a conveying structure, and a dispensing structure arranged in sequence; the label storage structure has a storage part, a lifting part, and a transmission part. The transmission part can drive the lifting part to lift under the action of an external force, and control the height position of the storage part; the label distribution structure includes a pasting component, a power component, and an annular track. The pasting component can slide along the annular track under the drive of the power component, and the transmission part is located on the sliding track of the pasting component; the conveying structure has a limiting part; the dispensing structure is installed on the conveying structure; the annular track has a first low point and a second high point. The storage part is located below the first low point, and the limiting part is located below the second high point. When the pasting component is at the first low point, the pasting component can pick up the label paper placed in the storage part. When the pasting component is at the second high point, the label paper pasted on the pasting component is located in the limiting part, and the lowest position of the pasting component is higher than the highest position of the limiting part.

[0008] In the above technical solution, the label paper is regularly laid on the surface of the belt through the label distribution structure, which facilitates the dispensing structure to dispense glue on the label paper. The first low point of the annular track facilitates the position of the pasting component to descend and paste the label paper. Since the position of the first low point is determined, the position where the pasting component pastes the label paper is also determined, ensuring the consistency of the dispensing position. Moreover, the use of the transmission component and the pasting component in cooperation makes the label paper in the storage part always at the same height, facilitating the cooperation with the label distribution structure; through the cooperation of several sets of devices, the dispensing work of the label paper is completed without manual operation, improving the production efficiency.

[0009] Further, the power component includes a motor, a support base, a support column, a support disk and a support frame. One end of the support column is fixed to the support base, and the other end is fixed to the support disk. One end of the support frame is fixed to the support base, and the other end is fixed to the motor. The motor is located on the side of the support disk away from the support column, and the motor is connected to the pasting component; the annular track is sleeved outside the support column, and the annular track is fixedly connected to the support column through a support rod, and the annular track is coaxially arranged with the support disk.

[0010] Further, the storage part includes a lifting chassis and an annular enclosure. The annular enclosure is sleeved outside the lifting chassis and is slidably connected to the lifting chassis. The annular enclosure is fixedly connected to the support column; the lifting part includes a base and a screw rod. The base is provided with a threaded hole, one end of the screw rod is threadedly installed in the threaded hole, and the other end is rotatably connected to the lifting chassis. The surface of the lifting chassis away from the screw rod and the annular enclosure form a receiving groove; the transmission part includes a hook double-action ratchet mechanism, a return spring and a force-bearing rod. The hook double-action ratchet mechanism includes a ratchet, a first pawl, a second pawl, a connecting rod, a fixed seat and a swing rod. The ratchet is fixedly sleeved outside the screw rod. One end of both the first pawl and the second pawl meshes with the ratchet, and the other end is rotatably arranged on the connecting rod. The connecting rod is rotatably arranged on the surface of the fixed seat. One end of the swing rod is fixedly connected to the connecting rod, and the other end is fixedly connected to the force-bearing rod through a reinforcing rod. The swing rod is located between the first pawl and the second pawl. One end of the return spring is fixedly connected to the swing rod, and the other end is fixedly arranged; the force-bearing rod is located on the sliding track of the pasting component. When the pasting component pushes the force-bearing rod to rotate, the hook double-action ratchet mechanism can drive the screw rod to rotate. When the force-bearing rod is separated from the pasting component, the force-bearing rod is reset under the stretching action of the return spring; the label storage structure and the label distribution structure are mutually matched, so that when the pasting component picks up the label paper, the placement position of the label paper can be changed, so that the label paper is always at a suitable height.

[0011] Further, the pasting component includes a rotating disk, an angle structure, a telescopic rod, a sleeve, a short rod, and a pasting plate. The rotating disk is located between the motor and the support disk and is coaxially rotatably connected to the support disk. The motor is coaxially fixedly connected to the rotating disk. One end of the angle structure is fixedly connected to the rotating disk, and the other end is fixedly connected to the telescopic rod. The axis direction of the telescopic rod is the same as the axis direction of the support column. The end of the telescopic rod away from the angle structure is fixedly connected to the side wall of the sleeve. The sleeve is sleeved outside the annular track. A first gap for the support rod to pass through is provided on the side wall of the sleeve. One end of the short rod is fixedly connected to the side of the sleeve away from the telescopic rod, and the other end is fixed with a pasting plate. The surface of the pasting plate away from the short rod has a low-viscosity glue layer. Since the height positions of the first low point and the second high point on the annular track are different, when the sleeve slides on the annular track, the height position of the sleeve will also change accordingly. The position of the sleeve can be adjusted by using the telescopic rod.

[0012] Further, the angle structure has a first connecting rod and a second connecting rod that are vertically connected. The first connecting rod is located on the surface of the support disk and is fixedly connected to the rotating disk. The second connecting rod is fixedly connected to the telescopic rod. The second connecting rod is slidably arranged on the side wall of the support disk through a slider.

[0013] Further, balls are arranged at the parts of the inner side wall of the sleeve close to the telescopic rod and the short rod to reduce the friction between the sleeve and the annular track.

[0014] Further, when the force-bearing rod is driven by the pasting component, the force-bearing rod contacts the short rod.

[0015] Further, the conveying structure includes a belt and a support frame; the limiting part includes a first limiting strip and a second limiting strip fixed on the support frame. Both the first limiting strip and the second limiting strip are arc-shaped structures; when the pasting component is located at the second high point of the annular track, the pasting plate is located between the first limiting strip and the second limiting strip, the label paper is located between the first limiting strip and the belt, and between the second limiting strip and the belt.

[0016] Further, the glue-dropping structure includes a mounting frame and a dispensing machine. The mounting frame is fixedly arranged with the support frame, the dispensing machine is fixedly connected to the mounting frame, and the glue outlet nozzle of the dispensing machine is located above the belt.

[0017] Further, a color sensor is also installed on the mounting frame. The color sensor is used to detect whether there is a label paper on the belt, and the color sensor is signal-connected to the dispensing machine.

[0018] The beneficial effects of the present invention are:

[0019] In the present invention, by utilizing the cooperation of a label storage structure, a label distribution structure, a conveying structure, and a glue dripping structure, with the height position of the first low point remaining unchanged, the uniqueness of the relative position between the glue dripping structure and the label paper is maintained, so that the glue dripping positions on all label papers are the same, ensuring the consistency of the glue dripping positions, facilitating the improvement of the aesthetics of pasting. Moreover, during the overall operation process, no manual operation is required, which can effectively improve the efficiency of glue dripping and reduce labor costs. Additionally, by utilizing the cooperation of the transmission part and the pasting component, the highest position of the label paper is maintained unchanged, improving the smoothness of the overall use of the device.

Detailed implementation manner

[0027] The following description provides many different embodiments or examples for implementing different features of the present invention. The elements and arrangements described in the following specific examples are only used to concisely express the present invention, and they are only examples and not intended to limit the present invention.

[0028] Embodiment

[0029] This embodiment provides an automatic glue - dropping device, as Figures 1 to 4 shown, including a label storage structure, a label distribution structure, a conveyor structure 100, and a glue - dropping structure 400 arranged in sequence; the label storage structure has a storage part 210, a lifting part 220, and a transmission part 230. The transmission part 230 can drive the lifting part 220 to lift under the action of an external force to control the height position of the storage part 210; the label distribution structure includes an adhesive component 310, a power component 320, and an annular track 330. The adhesive component 310 can slide along the annular track 330 under the drive of the power component 320, and the transmission part 230 is located on the sliding track of the adhesive component 310; the conveyor structure 100 has a limiting part 110; the glue - dropping structure 400 is installed on the conveyor structure 100; the annular track 330 has a first low point and a second high point. The storage part is located below the first low point, and the limiting part 110 is located below the second high point. When the adhesive component 310 is at the first low point, the adhesive component 310 can pick up the label paper 500 placed in the storage part 210. When the adhesive component 310 is at the second high point, the label paper 500 pasted on the adhesive component 310 is located in the limiting part 110. The lowest position of the adhesive component 310 is higher than the highest position of the limiting part 110, that is, when the adhesive component 310 is at the second high point, the label paper 500 falls off.

[0030] In this embodiment, the first low point refers to the lowest point of the annular track 330 when the dispensing device is placed flat on a horizontal plane, and the second high point is the highest point of the annular track 330.

[0031] During use, the label distribution structure transfers the labels from the label storage structure to the belt 120, and conveys them to the lower part of the dispensing structure 400 through the belt 120 to complete the dispensing work; the entire process is completed by a mechanical structure without the need for manual labor, which can liberate the labor force; moreover, when laying the label paper 500 by using the label distribution structure, since the positions of the first low point and the second high point are both determined, on the one hand, when the pasting component 310 picks up the label paper 500, the connection position with the label paper 500 is unified, and on the other hand, after the pasting component 310 cooperates with the limiting part 110, the position where the label paper 500 detaches from the pasting component 310 is also unified. The unification of these two positions makes the relative position of the label paper 500 and the dispensing structure 400 determined, which is convenient for unifying the dispensing positions on the label paper 500; in addition, mechanical operation can improve the operation efficiency compared with manual operation.

[0032] The structure of the power component 320 in this embodiment is as Figure 1 shown. The power component 320 is mainly divided into two parts. One part is the part that provides power, that is, the motor 321, and the other part is the part that provides a supporting role, namely the support base 322, the support column 323, the support disc 324 and the support frame 325. Specifically, one end of the support column 323 is fixed to the support base 322, and the other end is fixed to the support disc 324. One end of the support frame 325 is fixed to the support base 322, and the other end is fixed to the motor 321. The motor 321 is located on the side of the support disc 324 away from the support column 323. The motor 321 is connected to the pasting component 310 and is used to drive the pasting component 310 to slide on the annular track 330; the annular track 330 is sleeved outside the support column 323, and the annular track 330 is fixedly connected to the support column 323 through a support rod, and the annular track 330 is coaxially arranged with the support disc 324.

[0033] The support base 322 is an important support part provided in this embodiment. For the convenience of use, transportation, etc., the label storage structure of this embodiment is also located on the surface of the support base 322; the support frame 325 is mainly used to fix the position of the motor 321, and the support disc 324 is used to assist the cooperation with the motor 321, so that the pasting component 310 can be transported on the annular track 330 according to a predetermined track.

[0034] The label storage structure provided in this embodiment is as Figure 1As shown in the figure, it is entirely arranged on the surface of the support base 322. Specifically, the storage part 210 includes a lifting chassis and an annular enclosure 211. The annular enclosure 211 is sleeved outside the lifting chassis and is slidably connected to the lifting chassis. The annular enclosure 211 is fixedly connected to the support column 323. The lifting part 220 includes a base 221 and a screw rod 222. The base 221 is fixed on the support base 322. There is a threaded hole on the base 221. One end of the screw rod 222 is threadedly installed in the threaded hole, and the other end is rotatably connected to the lifting chassis. The surface of the lifting chassis away from the screw rod 222 and the annular enclosure 211 form a receiving groove. The label paper 500 is located in the receiving groove. When the screw rod 222 is driven by the transmission part 230 to rotate, the relative position between the screw rod 222 and the base 221 will change, and the height of the screw rod 222 will also change. The height of the lifting chassis provided at the top of the screw rod 222 will also change, thereby changing the height of the label paper 500 in the receiving groove, so that the highest height of the label paper 500 is maintained stable, which is convenient for cooperation with the pasting component 310. Since the pasting component 310 picks up the label paper 500 at the first low point, the highest point of the annular enclosure 211 can be higher than the highest point of the label paper 500, but it should not be too high. It is necessary to ensure that the pasting component 310 can smoothly pass over the annular enclosure 211, thereby lowering to the first low point to pick up the label paper 500, and can also smoothly rise and pass over the annular enclosure 211 after picking up the label paper 500; the annular enclosure 211 is higher than the label paper 500 mainly to prevent the label paper 500 from being unconstrained and falling off from the receiving groove under unexpected circumstances; to further determine the glue-dropping position of the label paper 500, the shape of the label paper 500 is preferably the same as the cross-sectional shape of the receiving groove. In this embodiment, the label paper 500 is made of hard cardboard and will not be wrinkled or folded by the wind.

[0035] The structure of the transmission part 230 is as Figures 1 to 3 shown. The transmission part 230 includes a hook double-acting ratchet mechanism, a return spring 231, and a force-bearing rod 232. The function of the transmission part 230 is mainly realized by the hook double-acting ratchet mechanism. In this embodiment, an existing hook double-acting ratchet mechanism is directly selected as the main part, and then the return spring 231 and the force-bearing rod 232 are added. Through the cooperation of the force-bearing rod 232 and the pasting component 310, a part of the power of the pasting component 310 is transferred to the force-bearing rod 232, and the force-bearing rod 232 then transfers the power to the hook double-acting ratchet mechanism, causing the ratchet 234 to rotate, thereby driving the rotation of the screw rod 222 to achieve the rise and fall of the lifting chassis.

[0036] The hook-headed double-acting ratchet mechanism includes a ratchet wheel 234, a first pawl 235, a second pawl 236, a connecting rod 237, a fixed seat 238, and a swing rod 239. The ratchet wheel 234 is fixedly sleeved outside the screw rod 222. One end of both the first pawl 235 and the second pawl 236 meshes with the ratchet wheel 234, and the other end is rotatably arranged on the connecting rod 237. The connecting rod 237 is rotatably arranged on the surface of the fixed seat 238. The fixed seat 238 is fixed on the surface of the support base 322. One end of the swing rod 239 is fixedly connected to the connecting rod 237, and the other end is fixedly connected to the force-bearing rod 232 through a reinforcing rod 233. The swing rod 239 is located between the first pawl 235 and the second pawl 236. One end of the return spring 231 is fixedly connected to the swing rod 239, and the other end is fixed on the surface of the support base 322; the force-bearing rod 232 is located on the sliding track of the pasting assembly 310. When the force-bearing rod 232 is not affected by external forces, the structure of the transmission part 230 is as Figure 2 shown. When the force-bearing rod 232 is driven by the pasting assembly 310, the structure of the transmission part 230 is as Figure 3 shown; when the pasting assembly 310 pushes the force-bearing rod 232 to rotate, the force-bearing rod 232 transfers its own rotation track to the swing rod 239. The swing rod 239 rotates, driving the first pawl 235 and the second pawl 236 to move, prompting the ratchet wheel 234 to rotate. When the force-bearing rod 232 is separated from the pasting assembly 310, the force-bearing rod 232 is reset under the stretching action of the return spring 231; by cooperating the label storage structure and the label distribution structure, when the pasting assembly 310 picks up the label paper 500, the placement position of the label paper 500 can be changed, so that the label paper 500 is always at an appropriate height.

[0037] The structural diagram of the pasting assembly 310 is as Figure 1 and Figure 4As shown, the pasting assembly 310 includes a rotating disk 311, a corner structure 312, a telescopic rod 313, a sleeve 314, a short rod 315 and a pasting plate 316. The rotating disk 311 is located between the motor 321 and the support disk 324, and is coaxially rotatably connected to the support disk 324. The motor 321 is coaxially fixedly connected to the rotating disk 311, and the motor 321 drives the rotating disk 311 to rotate; the corner structure 312 is used to be clamped on the support disk 324, one end of the corner structure 312 is fixedly connected to the rotating disk 311, and the other end is fixedly connected to the telescopic rod 313, the axial direction of the telescopic rod 313 is the same as the axial direction of the support column 323, the end of the telescopic rod 313 away from the corner structure 312 is fixedly connected to the side wall of the sleeve 314, and the sleeve 314 sleeve The side wall of the sleeve 314 is provided with a first gap for the support rod to pass through outside the annular track 330, so as to prevent the support rod from affecting the sliding of the sleeve 314 on the annular track 330. One end of the short rod 315 is fixedly connected to the side of the sleeve 314 away from the telescopic rod 313, and the other end is fixed with an adhesive plate 316. The surface of the adhesive plate 316 away from the short rod 315 has a low-viscosity glue layer 317. The low-viscosity glue layer 317 can be set in the form of pasting. When the viscosity is weakened to the point that the label paper 500 cannot be adhered, it can be torn off and replaced. Alternatively, the adhesive plate 316 can be replaced and the low-viscosity glue layer 317 can be used to adhere the label paper 500. At the same time, after the label paper 500 falls off, no glue marks will be left on the label paper 500.

[0038] Driven by the motor 321, the sleeve 314 slides on the circular track 330. Since the second highest point is higher than the first lowest point, the distance between the sleeve 314 and the corner structure 312 will change when the sleeve 314 slides. In this embodiment, a telescopic rod 313 is used for adjustment. In other embodiments, a spring can also be used for adjustment. However, the spring is easy to bend, so you need to pay attention to the selection of the spring when using it.

[0039] After the sleeve 314 is in the first position, the position of the sleeve 314 and the pasting plate 316 is gradually lowered, and the pasting plate 316 falls into the accommodating groove to stand the label paper 500. Then the position of the sleeve 314 and the pasting plate 316 is gradually raised and drawn out of the accommodating groove. Then the short rod 315 contacts the force rod 232, and the short rod 315 drives the force rod 232 to rotate. The screw 222 rises a little. After the short rod 315 is disengaged from the force rod 232, the sleeve 314 and the pasting plate 316 continue to slide along the annular track 330, and then the label paper 500 enters the limiting portion 110. The sleeve 314 and the pasting plate 316 also reach the second highest point. As the sleeve 314 continues to slide, the label paper 500 is restricted by the limiting portion 110, and is separated from the pasting plate 316 and falls onto the belt 120.

[0040] The corner structure 312 has a first link 312a and a second link 312b that are vertically connected. The first link 312a is located on the surface of the support disk 324 and is fixedly connected to the rotating disk 311. The second link 312b is fixedly connected to the telescopic rod 313. The second link 312b is slidably arranged on the side wall of the support disk 324 through a slider. There is a support point between the second link 312b and the support disk 324, which can support the gravity of the pasting assembly 310.

[0041] To reduce the friction generated between the inner side wall of the sleeve 314 and the surface of the annular track 330 when the sleeve 314 slides on the annular track 330, ball bearings 318 are provided at the parts of the inner side wall of the sleeve 314 close to the telescopic rod 313 and the short rod 315, improving the smoothness when the sleeve 314 slides.

[0042] The conveying structure 100 includes a belt 120 and a support frame. The conveying structure 100 belongs to the prior art and will not be elaborated here, and the related drawings are also omitted; the limiting part 110 includes a first limiting strip 111 and a second limiting strip 112 fixed on the support frame. Both the first limiting strip 111 and the second limiting strip 112 are arc-shaped structures; along the sliding direction of the pasting assembly 310, the rear ends of the first limiting strip 111 and the second limiting strip 112 are connected to the support frame. When the pasting assembly 310 is at the second highest point of the annular track 330, the pasting plate 316 is located between the first limiting strip 111 and the second limiting strip 112, the label paper 500 is located between the first limiting strip 111 and the belt 120, and between the second limiting strip 112 and the belt 120. Generally, when the pasting assembly 310 has not reached the highest point, the label paper 500 has already entered the limiting part 110. When the position of the pasting assembly 310 continues to rise to the second highest point, the label paper 500 falls off the pasting plate 316 onto the belt 120 under the restriction of the limiting part 110 and starts to be conveyed; in addition, in this embodiment, when the sleeve 314 is at the second highest point, the label paper 500 abuts against the connection position of the limiting part 110 and the support frame. When the pasting part is too tightly adhered to the label paper 500 and the label paper 500 does not fall off, at this time, since the other end of the label paper 500 abuts against the connection position of the limiting part 110 and the support frame, the label paper 500 cannot move forward. When the pasting plate 316 continues to slide, the label paper 500 will eventually fall off.

[0043] The epoxy resin dispensing structure 400 includes a mounting bracket 410 and a dispensing machine 420. The mounting bracket 410 is fixedly arranged with the support frame, the dispensing machine 420 is fixedly connected to the mounting bracket 410, and the glue outlet nozzle 421 of the dispensing machine 420 is located above the belt 120. The dispensing machine 420 is a commercially available dispensing machine 420 with a fixed position. When the position of the label paper 500 is determined, the epoxy resin dispensing position is easy to control. A color sensor 600 is also installed on the mounting bracket 410. The color sensor 600 is used to detect whether there is label paper 500 on the belt 120, and the color sensor 600 is signal-connected to the dispensing machine 420. In this embodiment, the color of the label paper 500 is significantly different from the color of the belt 120, which is convenient for the color sensor to identify. When the color sensor detects the label paper 500, it transmits a signal to the dispensing machine 420, and the dispensing machine 420 starts to dispense epoxy resin. The amount of epoxy resin dispensed by the dispensing machine 420 each time is fixed. After the epoxy resin dispensing is completed, it waits for the next signal to come.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
