Description

Dispenser device using a crank mechanism

[0001] The present invention relates to a dispenser device using a crank mechanism, and more particularly, to a dispenser device using a crank mechanism that causes contents to be discharged by pressing a pumping mechanism of a pump container.

[0002] Pump containers are designed to discharge a certain amount of contents depending on the degree of pressing of the pumping device, and are mainly used as containers for cosmetics, detergents, shampoos, syrups, flavoring sauces, and raw materials for cafes such as milk.

[0003] When these pump containers are used as raw material containers in cafes, liquid raw materials such as syrup or milk are discharged in a controlled manner according to the degree to which the pumping device is pressed, and then a mixing process is performed in which they are added to the original liquid.

[0004] However, the pump containers used in existing cafes require a beverage worker, such as a barista, to manually press them each time. This continuous pressing increases worker fatigue and may cause damage to certain areas due to increased fatigue.

[0005] Moreover, if the worker has little experience in making drinks in a cafe, the amount of contents dispensed in response to the ordered drinks may not be consistent, which may result in inconsistent flavors and lower satisfaction and quality reliability of the drinks.

[0006] As a related prior art for solving these problems, an automatic liquid supply device is disclosed in Patent No. 10-2589134.

[0007] The above prior art automatically pressurizes a pump so that syrup or sauce required for beverage production can be supplied in a quantity according to a recipe, and includes as its main components a pressurizing part installed on the upper part of a case, a mixing part that mixes by rotating a cup in the case, and a detection sensor that detects the position of the pump.

[0008] The pressurizing part of the prior art is configured such that when the pressurizing motor operates and rotates, the crank rotates, and the connecting rod coupled to the crank reciprocates up and down due to the rotation of the crank, and the slide bar moves up and down according to the up and down reciprocating motion of the connecting rod to pressurize the pump.

[0009] The pressurizing part of this prior art has a structure in which the crank and the connecting rod almost overlap at the top dead center of the slide bar that pressurizes the pump, and a structure in which the crank and the connecting rod overlap at the bottom dead center of the slide bar.

[0010] Accordingly, in the downward movement of the slide bar pressurizing the pump, the speed of the pump increases to the maximum point when the crank is rotated 0 to 90 degrees, and then decreases to the minimum point when the crank is rotated 90 to 180 degrees, and then, in the return of the pump, the speed of the pump changes in the opposite order.

[0011] However, since the pressurizing part of the prior art does not have a constant pressurizing speed of the pump depending on the rotational position of the crank, fluctuations in the discharge flow rate occurred, with the pump rapidly operating from the 0 to 90 degree position of the crank to discharge the contents and then decelerating from the 90 to 180 degree position to discharge the contents. In other words, since changes in the pressing speed occurred during the discharge operation of the pump, the discharge flow of the contents was not smooth, and there was a possibility that the contents would scatter due to impact after being discharged into the container.

[0012] In addition, in the return operation of the pressurized portion, the slide bar connected to the crank does not return quickly, and although the speed increases between 180 and 270 degrees according to the rotation, there is an aspect in which the return speed decreases between the 270 and 360 degree positions, so there was a problem in that the return after the discharge operation of the pump was delayed and it took time until the next operation.

[0013] The present invention, in order to solve the above problems, provides a dispenser device using a crank mechanism, which enables automatic quantitative discharge of the pump regardless of an operator, in which the pressing motion in the discharge of the pump is performed gradually and consistently to ensure smooth discharge flow of the pump, and in which the return motion of the pump is performed rapidly to reduce the return delay of the pump and enable rapid switching to the next discharge motion.

[0014] The present invention comprises a main body having a pump container accommodated therein; an operating mechanism mounting plate fixedly erected on one side of the pump in the main body; a driving motor fixed horizontally to one surface of the operating mechanism mounting plate; a reducer coupled to the driving motor and having a driving shaft passing through the operating mechanism mounting plate; and a crank mechanism connected to the driving shaft of the reducer to press and operate the pump, wherein the crank mechanism comprises: a driving link having one end coupled to the driving shaft on the other surface of the operating mechanism mounting plate; a movable link having one end rotatably coupled to the other end of the driving link; a pressing link having one end rotatably coupled to the other end of the movable link and a middle end rotatably coupled to the uppermost part of the operating mechanism mounting plate at an upper position of the driving shaft; And a cloud roller rotatably coupled to the other end of the pressing link and in contact with the upper surface of the pump, the pressing link is rotated downward at a certain angle from the movable link by the driving link to bring the cloud roller into contact with the pump, and the pump is pressurized to a position where the driving link and the movable link are arranged in an upright position, and the cloud roller provides a pressing pressure corresponding to the operating resistance of the pump, and a dispenser device using a crank mechanism is provided, wherein the descending time from the highest point to the lowest point is set longer than the ascending time from the lowest point to the highest point.

[0015] At the lower dead point of the above-mentioned cloud roller, the driving link and the movable link are arranged upright in a straight line or at a constant angle, and the pressing link forms an angle of less than 45 degrees downward with respect to the vertical line. At the upper dead point of the above-mentioned cloud roller, the driving link and the movable link are arranged to overlap, and the pressing link can form an angle of less than 20 degrees upward with respect to the horizontal line.

[0016] The above reducer may include a gearbox coupled to one surface of the operating mechanism mounting plate; a worm gear connected to the rotational shaft of the driving motor inside the gearbox; and a worm wheel coupled to the driving shaft so as to be gear-coupled to the worm gear inside the gearbox.

[0017] The configuration of the present invention may further include an input unit provided on an external side of the main body to input the number of operations of the pump; a position detection sensor that detects the number of rotations of the crank mechanism inside the main body; a control unit provided on the main body and connected to the input unit and the position detection sensor; and a display unit connected to the control unit to display the number of operations of the pump by the input unit on the outside of the main body.

[0018] The main body includes a base body in which the pump container is received and placed; a middle body including a horizontal plate connected to and fixed to an upper portion of the base body, a central receiving plate protruding upward from a central portion of the horizontal plate and provided to surround a pump and a discharge pipe of the pump container, and a partition plate connected perpendicularly to one side of the central receiving plate; and an upper body coupled to the middle body to close both sides of the middle body and to which the input unit, the control unit, and the display unit are coupled, wherein a battery for supplying driving power can be received between the partition plate of the middle body and a side wall portion of the upper body.

[0019] The present invention according to the above configuration can provide a dispenser device using a crank mechanism that enables automatic quantitative discharge of the pump regardless of an operator, in which the pressing motion in the discharge of the pump is performed gradually and consistently to ensure smooth discharge flow of the pump, and in which the return motion of the pump is performed rapidly to reduce the return delay of the pump and enable rapid switching to the next discharge motion.

[0031] As illustrated in FIGS. 1 to 5, a dispenser device (100) using a crank mechanism according to an embodiment of the present invention comprises: a main body (110) in which a pump container (101) having a pump (102) is accommodated therein; an operating mechanism mounting plate (119) that is fixed to stand on one side of the pump (102) in the main body (110); a driving motor (120) that is fixed horizontally to one surface of the operating mechanism mounting plate (119); a reducer (130) that is coupled to the driving motor (120) and has a driving shaft (135) that passes through the operating mechanism mounting plate (119); and a crank mechanism (140) that is connected to the driving shaft (135) of the reducer (130) and operates the pump (102) by pressing.

[0032] The main body (110) includes a base body (111) in which a pump container (101) is received and placed; a horizontal plate (113a) connected to and fixed to the upper end of the base body (111); a central receiving plate (113b) protruding upward from the center of the horizontal plate (113a) and provided to surround the pump (102) and discharge pipe (103) of the pump container (101); and a middle body (113) including a partition plate (113c) connected to one side of the central receiving plate (113b); and an upper body (114) coupled to the middle body (113) to close both sides of the middle body (113).

[0033] The base body (111) and the middle body (113) of this main body (110) are structured such that the lower part of the middle body (113) is inserted into the interior of the base body (111). The middle body (113) includes a lower insertion part (113d) having a fastening hole provided so that it can be inserted into the interior of the base body (111) and coupled, a catch (113e) supported on the upper part of the base body (111), and an upper fastening part (113f) having a fastening hole provided so that it can be coupled to the rear surface of the upper body (114).

[0034] The central receiving plate (113b) is provided with a front opening (113b-1) so that the discharge pipe (103) is exposed to the front of the main body (110) and a rear opening (113b-2) of a right angle shape so as to prevent interference during movement of the crank mechanism (140) at the upper rear side.

[0035] The partition plate (113c) is integrally provided on the horizontal plate (113a) and the central receiving plate (113b) and is arranged to extend from the central receiving plate (113b) to the rear wall of the middle body (113), thereby acting as a barrier for the battery (116) and the crank mechanism (140).

[0036] A battery receiving portion (115) is provided in the grating plate (113c) to receive a battery (116) for driving a crank mechanism (140). The battery receiving portion (115) has a square box shape corresponding to the shape of the battery (116) and has a slot structure with an open front.

[0037] Accordingly, a battery receiving portion (115) is placed between the partition (113c) of the middle body (113) and the side wall portion of the upper body (114), and a battery (116) that supplies driving power can be received in the battery receiving portion (115).

[0038] The upper body (114) has a “ㄷ” shape and may include a front portion (114a) in the “ㄱ” shape, a pair of side brackets (114b) for side connection of the front portion (114a), and a support panel (114c) for bottom support connection of the front portion (114a).

[0039] On both sides of the front portion (114a) of the upper body (114), side joints (114a-1) corresponding to the side brackets (114b) are formed, and on the inside thereof, bosses (114a-2) for fastening screws for fixing the circuit board in an inclined direction are formed.

[0040] The operating mechanism mounting plate (119) has a horizontal fixed plate provided at the lower end to be coupled to the horizontal plate (113a) at the rear of the central receiving plate (113b), and a through hole is provided to allow the driving shaft (135) to pass through.

[0041] A drive motor (120), a reducer (130), and a crank mechanism (140) for operating the pump (102) of the pump container (101) are installed on the operating mechanism mounting plate (119).

[0042] Figure 6 is a conceptual diagram of the reducer of Figure 4.

[0043] Referring to FIGS. 3, 4, and 6, the reducer (130) may include a gearbox (131) coupled to one surface of the operating mechanism mounting plate (119), a worm gear (132) connected to the rotational shaft of the driving motor (120) inside the gearbox (131), and a worm wheel (133) coupled to the driving shaft (135) so as to be gear-coupled to the worm gear (132) inside the gearbox (131).

[0044] Accordingly, the torque transmitted from the drive motor (120) to the drive shaft (135) through the worm gear (132) and the worm wheel (133) can be increased and output from the drive shaft (135) to operate the crank mechanism (140).

[0045] Fig. 7 is a side view of the pump container and crank mechanism of Fig. 4, and the front part of the middle body, and Fig. 8 is an operating state diagram of the crank mechanism of Fig. 7.

[0046] Referring to FIGS. 3, 4, 7, and 8, the crank mechanism (140) comprises a drive link (141) having one end coupled to a drive shaft (135) on the other surface of the operating mechanism mounting plate (119); a movable link (142) having one end rotatably coupled to the other end of the driving link (141); a push link (143) having one end rotatably coupled to the other end of the movable link (142) and a middle end rotatably coupled to the uppermost portion of the operating mechanism mounting plate (119) at an upper position of the driving shaft (135); and a rolling roller (145) rotatably coupled to the other end of the pushing link (143) and in rolling contact with the upper surface of the pump (102).

[0047] The crank mechanism (140) is a four-section link having a driving link (141), a movable link (142), and a pressing link (143) as the first to third links in that order, and the operating mechanism mounting plate (119) serves as a base, and is structured to be arranged obliquely from the operating mechanism mounting plate (119).

[0048] The driving link (141) can rotate 360 ​​degrees by the driving shaft (135) as the first link to rotate the movable link (142). The movable link (142) connects the driving link (141) and the push link (143) and is provided with a structure that can move in conjunction with the rotational movement of the driving link (141) and the push link (143).

[0049] The movable link (142) transmits the driving force of the drive link (141) to the push link (143) as a second link, while the center point moves along a certain trajectory line on the operating mechanism mounting plate (119) and rotates around the center point.

[0050] The press link (143) is a structure in which the middle part of the third link is rotatably connected to the operating mechanism mounting plate (119), and is a structure that extends above the pump container (101) to pressurize the pump container (101).

[0051] Since the middle part of this push link (143) is rotatably connected to the operating mechanism mounting plate (119), the force transmitted from the movable link (142) can be directly transmitted to the pump (102) of the pump container (101) based on the rotation point.

[0052] The push link (143) is rotated downward at a certain angle by the movable link (142) which is rotated by the drive link (141) to bring the cloud roller (145) into contact with the pump (102). At this time, the cloud roller (145) is moved downward to a position where the drive link (141) and the movable link (142) are arranged in an upright position to pressurize the pump (102).

[0053] In addition, the push link (143) is linked to the movable link (142) by the drive link (141) and rotates up and down. That is, the push link (143) is linked to the movable link (142) and seesaws up and down to move the cloud roller (145) up and down, thereby operating the pump (102) of the pump container (101).

[0054] The movement of the cloud roller (145) provided at the other end of the push link (143) moving from the top dead point to the bottom dead point is a pump operation movement that pressurizes the pump (102) of the pump container (101) to discharge the contents of the pump container (101) to the outside, and conversely, the return movement from the bottom dead point to the top dead point is a return movement.

[0055] At this time, when the driving link (141) and the movable link (142) are arranged to overlap each other on the lower side of the driving shaft (135), the cloud roller (145) at the other end of the pressing link (143) rises and is arranged on the upper side of the pump (102). Conversely, when the driving link (141) and the movable link (142) are arranged to be almost erect or at an obtuse angle on the upper side of the driving shaft (135), the cloud roller (145) at the other end of the pressing link (143) descends and is arranged on the lower side while pressing the pump (102).

[0056] The crank mechanism (140) that operates in this way can substantially exert greater operating force to operate the pump (102) than the return motion to the pump (102) by implementing that the time for the downward motion of the push link (143) from the top dead center to the bottom dead center, when lowering the cloud roller (145), is longer than the time for the upward motion of the push link (143) from the bottom dead center to the top dead center, when raising the cloud roller (145).

[0057] In this embodiment, at the bottom dead center of the cloud roller (145), the drive link (141) and the movable link (142) are arranged upright while forming a line or a certain angle, and the push link (143) forms an angle of less than 45 degrees downward with respect to the vertical line, and at the top dead center of the cloud roller (145), the drive link (141) and the movable link (142) are arranged to overlap, and the push link (143) can form an angle of less than 20 degrees upward with respect to the horizontal line.

[0058] The cloud roller (145) can smoothly operate the pump (102) while overcoming the operating resistance of the pump (102) by setting the descending time from the highest point to the lowest point longer than the ascending time from the lowest point to the highest point to provide a pressing pressure corresponding to the operating resistance of the pump (102), and returns quickly upon return to prepare for the next pump operation.

[0059] Meanwhile, referring to FIGS. 1 to 5 and FIGS. 7 and 8, the present embodiment may further include an input unit (150) provided on an external side of the main body (110) to input the number of operations of the pump (102); a position detection sensor (155) that detects the number of rotations of the crank mechanism (140) inside the main body (110); a control unit (160) provided on the main body (110) and connected to the input unit (150) and the position detection sensor (155); and a display unit (170) connected to the control unit (160) to display the number of operations of the pump (102) by the input unit (150) on the outside of the main body (110).

[0060] These input unit (150), control unit (160), and display unit (170) are arranged on the front part (114a) of the upper body (114).

[0061] The front part (114a) of the upper body (114) has a shape like the letter “ㄱ”, and button slots for the input part (150) are arranged horizontally on the inclined upper surface, and LED holes for the display part (170) are arranged vertically on the side.

[0062] The input unit (150) is arranged with the first to fifth buttons (151) and is connected to a circuit board provided as a control unit (160).

[0063] According to this embodiment, when the sequential number of each button (151) indicates the number of times the pump (102) is operated, when the first button (151) is pressed, the control unit (160) operates the drive motor (120) to rotate the drive shaft (135) of the crank mechanism (140) once, thereby operating the pump (102) of the pump container (101) once by the cloud roller (145) through the movable link (142) and the pressing link (143).

[0064] Accordingly, the contents are discharged once through the discharge pipe (103) of the pump container (101), and the pump (102) is detected once by the position detection sensor (155) that detects one rotation of the drive shaft (135) of the crank mechanism (140), and output to the display unit (170) through the control unit (160).

[0065] The display unit (170) is provided with first to fifth LEDs (171) that operate in an elevator manner on the front of the upper body (114) to correspond to the number of operations of the input unit (150) and the pump (102). For example, for one operation of the pump (102), the first LED at the lowest position may be turned on, and for two pump operations, the first LED and the second LED immediately above may be turned on.

[0066] Figure 9 is a graph showing the position and descending and ascending speed of the cloud roller by the operation of the crank mechanism over time.

[0067] Referring to FIGS. 7 to 9, as described above, the dispenser device (100) using the crank mechanism according to the present embodiment can provide sufficient operating pressure to smoothly operate the pump (102) by setting the operating time of the pump (102) of the crank mechanism (140) to be longer than the return time, and in particular, since the drive link (141) of the crank mechanism (140) rotates a full 360 degrees to move the cloud roller (145) up and down through the movable link (142) and the push link (143), the drive link (141) rotates from the lower side to the upper side, and thus, the operating power gain can be obtained during the operating time of the pump (102) by the cloud roller (145) that stands up together with the movable link (142).
