Description

Technical Field

[0001] The present invention relates to a dispensing device for dispensing a material from a cylinder filled with a viscous and a non-viscous material. Background Technology

[0002] To date, various configurations for such dispensing devices are known. These dispensing devices are capable of dispensing single-component materials using either so-called single-component cylinders or coaxial cylinders, or dispensing multi-component materials using side-by-side cylinders, which can be in the form of so-called solid cylinders or foldable, correspondingly sausage bag-type cylinders.

[0003] However, there is a persistent need for further improvements to this device. Summary of the Invention

[0004] Therefore, the object of the present invention is to provide an improved configuration for such a dispensing device. This object is achieved by the subject matter of independent claim 1. Preferred modifications can be obtained from the dependent claims.

[0005] According to the present invention, a dispensing device for dispensing viscous and non-viscous materials from a cylinder includes a base structure, a plunger, a drive mechanism, and a drive member. The plunger is configured to translate relative to the base structure, the drive mechanism is configured to cause dispensing movement of the plunger relative to the base structure, and the drive member is configured to transmit a driving force from the drive mechanism to the plunger. The dispensing device further includes a support member and a guide device. The drive member is provided on the support member, and the guide device centers a first end of the drive member on the plunger. The support member is configured to translate and rotate relative to the base structure during the dispensing movement of the drive member to retain the first end of the drive member centered on the plunger.

[0006] Translational movement of the support member used to center the drive member allows for the prevention of shear forces acting on the plunger. For clarity, it should be noted that the statement "drive mechanism configured to cause dispensing movement of the plunger relative to the base structure" effectively means that the drive mechanism is configured to realize the movement of the plunger into and along the cylinder (particularly via the drive member) (the cylinder is connected to the dispensing device, particularly to the base structure) to press material out of the cylinder for dispensing.

[0007] Preferably, the driving member is a flexible rod, and the supporting member is a rod-drum shape, which is wound by at least a portion of the driving member, particularly more than once, preferably multiple times.

[0008] This configuration is very robust and allows for implementations of dispensing devices that allow for very long dispensing paths for plungers (especially for dispensing material from relatively long cylinders). The term "flexible" is understood in this document to mean that the drive member is reversibly (especially elastically) deformable perpendicular to its length.

[0009] Preferably, a support member is provided on a splined shaft that is rotatably fixed but translationally movable, the splined shaft being rotatable relative to the base structure to cause distributed movement of the drive member. The splined shaft is connected to a motor gearbox for rotating the splined shaft.

[0010] This configuration for driving the support members to cause distributed movement of the drive members is very compact yet robust.

[0011] Preferably, when connected to the base structure, the longitudinal axis of the motor gearbox is aligned parallel to the longitudinal axis of the cylinder. The motor gearbox is connected to the splined shaft via at least one (preferably multiple) of the following components: spur gear, compound gear, bevel gear, worm gear, wheel, belt drive, chain, sprocket teeth, and / or friction wheel.

[0012] This configuration can be implemented with minimal width. The additional parts listed allow for a reliable connection between the motor gearbox and the drive drum, enabling a very compact overall configuration.

[0013] Preferably, when connected to the base structure, the longitudinal axis of the motor gearbox is perpendicularly aligned with the longitudinal axis of the cylinder, and the motor gearbox is directly connected to the spline shaft.

[0014] This configuration can be achieved with a minimal number of parts, and is therefore very robust and durable.

[0015] Preferably, the support member is configured to translate in a direction perpendicular to the translational movement direction of the plunger during the dispensing movement.

[0016] This configuration is highly efficient at preventing unwanted shear forces acting on the plunger.

[0017] Preferably, the guiding device includes a guide bushing and / or at least one (especially multiple) guide wheels.

[0018] This guiding device allows for reliable and well-controlled guidance of the drive components during dispensing movement.

[0019] Preferably, the dispensing device is an electrically driven (particularly cordless) handheld device, and the drive mechanism includes a motor gearbox.

[0020] In this regard, it should be noted that the dispensing device can also be a manual dispensing device, which includes a gear lever mechanism to convert the action of pulling the lever of the dispensing device into the pushing movement of the plunger.

[0021] Preferably, the gear lever mechanism is adapted to convert the action of pulling the lever into a continuous or quasi-continuous pushing movement of the plunger.

[0022] This dispensing device is easy to transport and can be used flexibly.

[0023] Preferably, the dispensing device is a ground dispensing device configured to dispense material from a cylinder having a length of more than 0.5 m, and particularly from a cylinder having a length of 1.0 m or even longer.

[0024] For this type of distribution device, the lateral centering movement of the supporting members is particularly advantageous.

[0025] Preferably, the dispensing device includes an anti-drip device configured to be operated by the user to release the pressure applied to the piston by the drive member and thus to the cylinder, particularly by causing a small reverse movement of the end section of the drive member connected to the piston.

[0026] Undesirable chasing motion of the piston in the cylinder and the resulting leakage can be reliably prevented with this configuration.

[0027] Preferably, the anti-drip device includes an anti-drip finger acting on the drive member and a guide device, the guide device being used to prevent shear force on the plunger when the anti-drip finger is activated.

[0028] This configuration describes a simple yet reliable implementation for drip-proof devices.

[0029] Preferably, the base structure includes a connecting device for connecting the rear end of the cylinder or for securely but releasably retaining the central portion of the cylinder. The base structure has a length significantly shorter than the length of the cylinder to which it is to be connected.

[0030] This type of distribution device can be made very compact, especially for storage distribution devices.

[0031] Preferably, the base structure includes a retractable frame configuration configured to maintain cylinders of varying lengths.

[0032] This configuration allows for the reliable connection of cylinders of various lengths to the dispensing device.

[0033] Preferably, the base structure is configured such that the cylinder can be fixedly but releasably connected to the base structure.

[0034] In other words, when connected to the cylinder and during the dispensing operation, the cylinder does not move relative to the base structure. However, the cylinder can be released from the base structure so that it can be replaced by a new cylinder.

[0035] Preferably, the plunger is configured to translate into a cylinder connected to the base structure to dispense material from the cylinder.

[0036] This translational movement of the plunger results in the controlled dispensing of material from the cylinder.

[0037] Preferably, the dispensing device includes a stand configured such that the dispensing device can be stably placed on the ground in a substantially vertical orientation.

[0038] This configuration is very robust and easy to store, even if the distribution device is implemented in a fairly large manner.

[0039] Preferably, the drive member is flexible and wound around the support member. The dispensing device is configured such that rotational movement of the support member causes the drive member to unwind from the drive drum, and thus causes a translational axially guided force from the unwound drive member to the plunger, thereby causing the phase plunger to translate and dispense the movement relative to the base structure.

[0040] The rotation of the support member used to drive the drive component results in a very robust overall configuration with less slippage between the drive mechanism and the drive component.

[0041] Preferably, the first end of the drive member is securely connected to the plunger, and the second end of the drive member is securely connected to the support member, particularly via the axle plug.

[0042] Therefore, the risk of slippage between the support and drive components is minimized.

[0043] Preferably, the drive member is a flexible drive rod that is connected to the support member in a non-releasable manner (particularly via a piston).

[0044] This lever configuration was found to be very robust, yet still flexible enough for the intended functionality.

[0045] Preferably, the driving member is a continuous coil of spring material (such as spring steel) having a diameter of 10 mm to 25 mm, preferably 13 mm to 22 mm, wherein the coil is formed, in particular, of wire having a substantially square cross-section and / or a thickness corresponding to the pitch of the coil.

[0046] In this way, cost-effective springs can be implemented in the dispensing device. This allows for the use of various metals or materials other than steel. These characteristics of the drive components have been found to result in a simple and robust yet still reliable overall dispenser configuration.

[0047] Preferably, the drive member is formed of a first part of flexible material and a second part of rigid material, the first and second parts being connected to each other, such that the drive member is configured to transmit lateral forces along its length, but bends when a lateral force is applied to it.

[0048] This configuration enables highly optimized implementations for drive components with various options for customization. In this document, the term "rigid" means that during normal operation of the drive unit, the corresponding part cannot be deformed by a desired amount of force acting on it. In this document, the term "flexible" means that during normal operation of the drive unit, the corresponding part can be deformed by a desired amount of force acting on it.

[0049] Preferably, the drive member is formed of a plurality of substantially identical segments that are non-releasably connected to each other. Each of the segments particularly includes at least one (preferably multiple) spring member, connecting member, and / or spacer.

[0050] The cost of producing drive components can be reduced by using the same segments, and the listed parts have been found to be suitable for forming robust and reliable drive components.

[0051] Preferably, the drive member is configured to convert the rotational drive movement of the support member into the translational distribution movement of the plunger.

[0052] This implementation allows for a very compact overall configuration.

[0053] Preferably, the base structure is configured such that the 2k cylinders (e.g., so-called side-by-side cylinders) can be connected to the base structure in a fixed but releasable manner, parallel to each other. The dispensing device includes a separate plunger and a separate drive member for each cylinder, but only a single common drive mechanism. The drive mechanism, in particular, includes a separate support member for each drive member, and each drive member is driven by a single common motor gearbox (preferably a single electric common motor gearbox).

[0054] Using this dispensing device, material can be dispensed simultaneously from the 2k cylinder without the need for an additional dispensing device. The dispensing process is reliably synchronized across the 2k cylinder by using a common drive mechanism for each individual plunger. Attached Figure Description

[0056] Throughout the various accompanying drawings, the same reference numerals denote (at least functionally) the corresponding parts. Detailed Implementation

[0057] If able to Figure 1 The image shows a photograph of an exemplary prototype of a dispensing device 100 developed in conjunction with the present invention. The dispensing device 100 includes a base structure 48 configured to hold a cylinder 1, and a plunger 3 configured to actuate the plunger 3 (not visible here; see, for example, see...). Figure 2A and Figure 2B The drive mechanism (here, a motor with a battery-powered screwdriver) moves along the base structure 48 via the distribution of the cylinder 1, and the drive member 4 (not visible here; see, for example, see...) is configured to transmit the driving force from the drive mechanism to the plunger 3. Figure 2A and 2B The drive member 4 is surrounded by the shaft housing 14, which guides the movement of the drive member 4 and forms a central opening 65 (see also...). Figure 3 This allows the user to hold the dispensing device 100 by gripping it through the opening 65.

[0058] In the following text, reference will be made to Figure 2A and Figure 2B describe Figure 1 The internal structure and function of the distribution device 100.

[0059] The dispensing device 100 includes a circular drive spool 5 rotatably coupled to a base structure 48 (not shown). A drive member 4 is provided in a flexible manner and is at least partially wound around the drive spool 5. A first end of the drive member 4 is securely connected to a plunger 3, and a second end of the drive member 4 is securely connected to the drive spool 5, particularly to a piston 7 fixed to the drive spool 5. The plunger 3 is configured to push a piston 2 of the spool 1 through the spool 1 to dispense material from the spool 1.

[0060] In the illustrated embodiment, the drive drum 5 includes an inner circumferential surface with gear teeth that engage a pinion 6 for driving the drive drum 5. Alternatively, the gear teeth may be provided on the outer circumferential surface or side surface of the drive drum 5, or may be engaged by ratchet teeth via a ratchet or pawl device 37 (see reference). Figure 26A and Figure 26B (described below) to replace it for driving drive drum 5.

[0061] With this configuration, the rotational movement of the pinion 6 causes the rotational movement of the drive drum 5 (see...). Figure 2B (See the small arrow in the image), which causes the drive member 4 to unwind from the drive drum 5. This unwinding of the drive member 4 generates a translational axially guided force on the plunger 3, resulting in a translational distribution movement of the plunger 3, and thus causing the piston 2 to move relative to the base structure 48 through the translational distribution movement of the cylinder 1 (see [link]). Figure 2A and Figure 2B (The large arrow in the middle).

[0062] To ensure that the drive member 4 does not slide laterally from the drive drum 4 under reaction force during the dispensing process, the dispensing device 100 includes a guide device in the form of a guide recess 71 on the outer circumferential surface of the drive drum 5, thereby at least partially accommodating the drive member 4 (see [link]). Figure 2A Other configurations for this type of boot device will be referenced below. Figures 29 to 33 And further description.

[0063] The drive member 4 is configured to transmit driving force from the drive mechanism to the plunger 3, and can have various configurations. Some exemplary configurations will be given consideration to... Figures 4A to 6 As described below.

[0064] Typically, the drive member 4 is configured to transmit translational force while being flexible around a corner or drum, to form a compact overall configuration.

[0065] To meet these requirements, the drive component 4 can be formed as a continuous coil of spring steel, such as... Figure 4A and Figure 4B As shown in the image. The coil is preferably made of wire with a substantially square cross-section (see [reference]). Figure 4A The cut surface is formed. The wire can have a thickness corresponding to the pitch of the formed coil, so that when longitudinally aligned, the coil can form a tube with a closed outer surface, such as... Figure 4A As shown in the diagram. For a compact yet robust configuration, coils with a diameter of 10 mm to 25 mm are preferred, and more preferably coils with a diameter of 13 mm to 22 mm, such as commercially available springs with a diameter of 13.5 mm (correspondingly, springs with a diameter of 22 mm). With this particular configuration of the drive member 4, the drive member can transfer force longitudinally along the drive member 4, but the drive member can be guided / bent, for example, guided / bent around the drive drum 5 (e.g. Figure 2A and Figure 2B (As shown in the middle).

[0066] Alternatively, the drive member 4 can be composed of a first part 66 of alternating flexible material and a second part 67 of rigid material (see...). Figure 5A The first part 66 and the second part 67 are connected to each other to form a configuration that transmits lateral forces along its length, but bends when a lateral force is applied to it. Specifically, the drive member 4 can be formed from multiple substantially identical segments that are inextricably linked to each other, such as... Figures 5B to 5DAs shown in the diagram. Each of the segments may include at least one (preferably multiple) spring members serving as flexible parts 66, spacers (especially spacer plates) serving as rigid parts 67, and / or flexible parts 66 and rigid parts 67 for connecting segments and / or connecting different segments to each other.

[0067] According to another exemplary configuration, the drive member 4 can be formed of various rigid parts 67, each of which is sequentially connected to a common elongated flexible (particularly bendable) part 66, as in Figure 6 It is displayed in the middle.

[0068] To ensure that this at least partially flexible drive member 4 follows the desired movement path and does not buckle under a specific reaction force, such as in, for example, Figure 29 As shown in the diagram, the dispensing device 100 can be provided with various guiding devices.

[0069] As indicated above, this guide device can be shaped along the guide recess 71 of the drive spool 5 to prevent the flexible drive member 4 from sliding laterally away. To prevent... Figure 29 The radial lifting departure shown in the figure indicates that the dispensing device 100 can be provided with at least one clamshell 52 (such as...). Figure 30A and Figure 30B (as shown in the image) or at least one low-friction plate 53 (such as...) Figure 31 (as shown in the image), at least one (especially multiple) low-friction inserts 54 (such as...) Figure 32 (as shown in the image) and / or at least one (especially multiple) rollers 55 (such as...) Figure 33 (As shown in the middle).

[0070] and Figure 1 Similar to the prototype configuration, the dispensing device 100 can be electrically driven, particularly wireless, to form a handheld device. For this purpose, the drive mechanism 100 can be provided with a motor gearbox 9, such as... Figures 7A to 8B It is displayed in the middle.

[0071] refer to Figure 7A and Figure 7B The motor gearbox 9 can be provided parallel to the longitudinal axis of the cylinder 1 to form a configuration with a low width. Alternatively, the longitudinal axis of the motor gearbox 9 can be perpendicular to the longitudinal axis of the cylinder 1 so that the output force from the motor gearbox 9 on the drive drum 5 can be transferred more directly (see...). Figure 8A and Figure 8B ).

[0072] In order to transfer the output force from the motor gearbox 9 to the drive drum 5, the motor output gear 8 of the motor gearbox 9 can directly engage with the drive drum 5, such as... Figure 8A and Figure 8BAs shown in the diagram. Alternatively, at least one (preferably multiple) of the following can be provided: a spur gear, a compound gear, a bevel gear, a worm gear, a wheel, a belt drive, a chain, sprocket teeth, and / or a friction wheel, to connect the motor output gear 8 of the motor gearbox 9 to the pinion 6 that engages with the drive drum 5 (see [link]). Figure 7A and Figure 7B ).

[0073] like Figure 7A and Figure 7B The diagram further illustrates that the distribution device 100 can be equipped with a battery 10 (particularly integrated into a battery pack) to provide energy to the motor gearbox 9. Alternatively, an energy storage device for providing energy to the motor gearbox 9 can be directly integrated into the motor gearbox 9, such as, for example... Figure 8A and Figure 8B It is displayed in the middle.

[0074] For example, Figure 8A and Figure 8B The energy storage device can also be provided in the form of a battery 10. This battery 10 or energy storage device can be selected in a manner similar to that of a battery 10. Figure 7A and Figure 7B The distribution device 100 is arranged in a manner that is parallel to the motor axis and is positioned on or below the cylinder 1.

[0075] In the following text, refer to Figures 9A to 12B Various configurations will be described that allow for the connection of (particularly different widths) 2k cylinders 1 to the base structure 48 of the dispensing device 100 in a fixed but releasable manner.

[0076] In this configuration, the dispensing device 100 preferably includes a separate plunger 3 and a separate drive member 4 for each cylinder 1, but only a common drive mechanism. Each of the drive members 4 is provided on its own drive drum 5 (thus forming a component of the common drive mechanism). The drive drum 5 is driven by at least one pinion 6 connected to a common motor gearbox 9 (not shown here) to form a common drive mechanism for the two drive members 4.

[0077] To allow for lateral positioning variations in the 2k cylinder 1, so that the cylinder 1 with varying width can be reliably connected to the dispensing device 100, the dispensing device 100 can be provided with a guiding device, such as the guide wheel 19 of the guide drive member 4 (see...). Figures 9A to 10 To implement the variable position adjustment of the 2k cylinder 1, only one of the two drive members 4 can be provided with such a guide wheel 19, the latter of which is movable in the lateral direction (see...). Figure 9A and Figure 9B(The arrow in the image). For greater flexibility and even greater adjustability, the two drive members 4 can be guided by this laterally movable guide wheel 19, as shown in... Figure 10 As shown in the diagram. The guide wheel 22 can be replaced or supplemented by the guide bushing 22.

[0078] Alternatively, the dispensing device 100 can be provided with adjusting devices for changing the lateral distance between the individual parts used for dispensing material from the 2k cylinder 1, such as... Figure 11 The diagram is shown schematically. Here, the drive member 4 and the corresponding drive drum 5 are provided to be laterally displaceable relative to each other (see arrow). Each of the drive drums 5 engages with its own pinion 6, wherein the two pinions 6 are connected, for example, via a common splined drive shaft (not shown) to a common motor gearbox 9 (not shown).

[0079] Alternatively, the dispensing device 100 can be provided with adjusting devices for changing the orientation between individual parts used for dispensing material from the 2k cylinder 1, such as... Figure 12A and Figure 12B The diagram is shown schematically. Here, the two drive drums 5 are tilted relative to each other at a variable angle, but are engaged with each other via direct tooth engagement of a lateral gear ring 68. The variable angle ranges from, for example, 0° to 90°, particularly to 60° or even just 45°. Therefore, only one of the two drive drums 5 (the one on the left in this case) must be connected to the motor gearbox 9 (not shown) via a pinion 6. Alternatively, each of the drive drums 5 can engage with its own pinion 6, wherein the two pinions 6 are connected to each other via a universal joint (not shown).

[0080] As indicated above, given that Figure 1 For configurations with drive drum 5, and such Figure 13A and Figure 13B As shown, in the absence of such a drive drum, the drive member 4 can be guided through a shaft housing 14 that defines a curved (partially circular) path, which guides the direction of movement of the drive member 4. The radius of the drive drum 5 can be, for example, in the range of 5 cm to 25 cm, especially in the range of 10 cm to 20 cm, and particularly 16 cm.

[0081] The following will describe a device that does not have a drive drum 5 and has the following characteristics: Figure 13A and Figure 13B An exemplary embodiment of the drive mechanism of the distribution device 100 for the movement characteristics of the drive member 4 indicated in the figure.

[0082] For example in Figure 14A and Figure 14BAs shown, the drive mechanism can include a motor gearbox 9 connected to a drive shaft 11, the drive shaft 11 being threadedly engaged with a drive carriage 12, the drive carriage 12 being fixed to the drive member 4. The drive carriage 12 (particularly via longitudinal guide protrusions engaging corresponding guide recesses) is non-rotatable but axially movable within a retaining tube 16. This configuration results in the conversion of the rotational driving force from the motor gearbox 9 into a translational driving force on the drive member 4. This translational driving force is redirected via the shaft housing 14 before acting on the piston 2 within the cylinder 1 via the plunger 3, as if by... Figure 13A and Figure 13B The arrow in the text indicates this.

[0083] The threaded drive shaft 11 can be provided in such a way that its end section protrudes into the rear end section of the drive member 4 (e.g., Figure 14A and Figure 14B (as shown in the image), or the end segment is positioned parallel but misaligned relative to the rear end segment of the driving member 4 (e.g., ...). Figure 15A and Figure 15B (As shown in the middle).

[0084] Alternatively, the drive member 4 can be configured to define an external thread structure that engages with the threaded collet 17 of the drive mechanism, such as... Figure 16A and 16B As shown in the image. The threaded collet 17 is axially fixed but rotatable to the retaining tube 16 (not shown here), which is connected to... Figures 14A to 15B Similar to the retaining tube 16, the rotational movement of the threaded collet 17 causes the translational movement of the drive member 4.

[0085] Alternatively, the drive member 4 can be configured to define an internal thread structure that engages with a threaded spindle 18 connected to the motor gearbox 9 (not shown here) to convert the rotational driving force from the motor gearbox 9 into translational driving movement of the drive member 4 (see [link to relevant documentation]). Figure 17A and Figure 17B ).

[0086] In this regard, it should be noted that the developed dispensing device 100 is compatible with the simple cylinder 1, which is only provided with a plunger 2 (as in, for example, in...). Figures 2A to 3 , Figure 7A and Figure 7B (as shown in the image), and a cylinder 1 formed by a tube 15, in which a bladder 13 filled with material to be dispensed and a piston 2 (see image) are provided. Figures 13A to 17B ).

[0087] The following text will refer to Figures 18A to 20 Various configurations for a distribution device 100 (particularly for a ground distribution device 100) for a relatively large cylinder 1 are described.

[0088] If able to Figure 18A As can be seen, this configuration is preferably used with a cylinder 1 having a tube 15 that surrounds a sac 13 filled with material to be dispensed. Figure 18B An exemplary perspective view of such a dispensing device 100, provided with a housing 69 and a stand 70, is shown.

[0089] refer to Figure 18C and Figure 18D The drive member 4 of this dispensing device 100 can be provided on a support member 20 in the form of a rod-drum (particularly wound multiple times around the support member 20). The drive member 4 is guided by a guide device (in the form of a guide bushing 22) to center the end of the drive member 4 acting on the plunger 3 on the plunger 3. The support member 20 shown is provided rotatably fixed but translationally movable on a splined shaft 21, which is rotatably connected to a motor gearbox 9. Thus, the motor gearbox 9 can rotate the support member 20 to cause the unwinding dispensing movement of the drive member 4 described above.

[0090] The guide bushing 22 is provided in a fixed position relative to the cylinder 1 connected to the dispensing device 100, such that when the drive member 4 rotates and unwinds from the support member 20, the support member 20 translates in a direction Y perpendicular to the intended direction of movement of the plunger 3. When the dispensing device 100 illustrated in the first initial state is... Figure 18A , Figure 18C and Figure 18D The distribution device shown in the diagram is in its second final state after the distribution operation has been performed. Figures 18E to 18G When comparing, this central movement can be observed. Figure 18H The diagram shows... Figure 18D (Left side) and Figure 18G A direct comparison (on the right) is used to illustrate the described movement of the support member 20 in the direction Y during the dispensing process to keep the first end of the drive member 4 connected to the plunger 3 centered.

[0091] refer to Figure 19 It is noted that the second support member 20 can be connected parallel to the first support member 20 described above to a single splined shaft 21, and thus to a single motor gearbox 9. The second support member 20 has a second drive member 4 guided through a second guide bushing 20 to dispense material from a second cylinder 1 (which is correspondingly a foldable cylinder) connected to the dispensing device 100. Therefore, the configuration allows for the simultaneous dispensing of material from the 2k cylinder 1 connected to a single dispensing device 100.

[0092] like Figure 20As shown, the guide bushing 20 can be replaced by a pair of guide wheels 19, which are used to center the first end of the drive member 4.

[0093] Figure 21A and Figure 21B The illustration shows an additional configuration for the dispensing device 100, which has a drive member 4 wound around a spool 39, as referenced above. Figure 7A and Figure 7B The description of the drive roll 5 is similar.

[0094] However, the configuration shown herein is not electrically driven via a motor gearbox 9 coupled to the drive drum 5, but manually driven via a gripper plate driver for directly driving the drive member 4. The gripper plate driver includes a trigger 27 pivotally supported on a trigger axis 28 to achieve trigger rotation 29. The trigger 27 is coupled via a link 63 to a gripper plate 62 that grips the drive member 4 near the plunger 3. Pulling force on the trigger 27, which causes the indicated trigger rotation 29, results in a pushing force on the drive member 4, and thus a pushing force on the piston 2 of the cylinder 1 via the plunger 3. Although not shown here, the gripper plate driver can be provided with a return spring (not shown), particularly a return spring acting on the gripper plate 62, for resetting the gripper plate driver after the trigger 27 is released. Therefore, material from the cylinder 1 can be dispensed via a manual “pumping” operation of the trigger 27. During this dispensing operation, the drum 39 rotates passively so as not to obstruct the unwinding movement of the drive member 4 from the drum 39.

[0095] In an alternative configuration, where the drive member 4 itself is driven instead of the drum 39, the drive mechanism can include a nut driver with a drive nut 60 and a thrust bearing 61, which acts directly on the drive member 4 via a threaded engagement to convert the rotational movement of the drive nut 60 and the thrust bearing 61 into the translational movement of the drive member 4. For an electrically driven configuration, the drive nut 60 can engage with the motor output gear 8 of the electric motor gearbox 9, as it... Figure 22A and Figure 22B It is displayed in the middle.

[0096] Instead of the nut actuator connected to the plunger side section of the drive member 4 as described above, the drive mechanism can include a rotary worm actuator having a worm wheel 24 rotatably supported on the worm wheel shaft 25, such as Figure 23 As shown in the diagram. The worm gear 24 is threadedly engaged with the curved middle section of the drive member 4 to convert the rotational movement of the worm gear 24 into the translational movement of the drive member 4.

[0097] Given Figure 23It is noted that, if necessary, the drive drum 5 with a central opening 65 described above can be replaced by an idler wheel 23 without the central opening 65 to hold the dispensing device 100.

[0098] The configuration described above can provide a drip-proof device, as shown in the reference. Figure 24A and Figure 24B As exemplified below.

[0099] Here, the anti-drip device is implemented as an anti-drip finger 26, configured to be user-operated to release pressure applied to the piston 2 via the plunger 3 and drive member 4. In the illustrated embodiment, this release is caused by a small, opposite movement of the end portion of the drive member 4 connected to the plunger 3 from a dispensing position to a releasing position, in which the plunger 3 contacts the piston 2 (see [link to documentation]). Figure 24A In the released position, plunger 3 no longer contacts piston 2 (see...). Figure 24B Therefore, any remaining pressure applied to the piston 2 via the plunger 3 and drive mechanism 4 is released. To prevent misalignment of drive member 4 and / or shear force on plunger 3 when the anti-drip finger 26 is activated (i.e., pushed), a guide device in the form of a guide bushing 22 is provided around drive member 4 between the anti-drip finger 26 and plunger 3.

[0100] Figures 25A to 25D An alternative manually driven configuration is illustrated. This configuration includes a manually driven gear drive with a trigger 27 pivotally supported on trigger axis 28 (see reference above). Figure 21A and Figure 21B (The configuration described is similar). Trigger 27 is provided with a trigger gear 30 that engages with trigger driven gear 31. The trigger driven gear 31 is connected to a ring drive gear 33 via a one-way clutch 35, and the ring drive gear 33 is provided on a ring drive gear shaft 32 oriented parallel to the trigger axis 28. The ring drive gear 33 engages with a ring gear 34 formed along the inner circumference of the drive drum 5.

[0101] exist Figure 25C The rotation of the trigger 29 in the indicated direction causes the drive drum 5 to rotate, and thus causes the unwinding movement of the drive member 4 described above. Figure 25B During the rotation of the trigger 29 in the opposite direction indicated by the center, the one-way clutch 35 disengages, preventing rotation of the drive drum 5. To automatically induce this reset movement upon release of the trigger 27, the trigger 27 can be coupled to a reset spring (not shown).

[0102] According to alternatives, the manual drive configuration can include a manually driven ratchet driver, such as... Figure 26A and Figure 26BThe example is shown below. Here, the ratchet driver includes a trigger 27 connected to a trigger pivot 36. The trigger 27 is connected to a drive pawl 37 via a drive pawl pivot 42, and the drive pawl 37 engages with the drum ratchet teeth 38 of the drive drum 5, thereby carrying the drive member 4. In the illustrated embodiment, in Figure 26A The rotation of the trigger 29 in the direction indicated by the center causes the unwinding rotation of the drive drum 5 (in the clockwise direction).

[0103] To prevent undesirable (counterclockwise) winding rotation of the drive drum 5 from the state where the drive pawl 37 is disengaged from the drum ratchet teeth 38 during the reset movement of the trigger 27, a brake pawl 40 supported on the brake pawl pivot P is provided.

[0104] refer to Figure 27A and Figure 27B The base structure 48 can include a connecting device for securely but releasably connecting the rear end of the cylinder 1 to the dispensing device 100. The connecting device shown includes a dispenser body 45 having a support boss 43 configured to engage with the rear portion of the cylinder 1. Furthermore, the connecting device includes a gripping ring 47 pressed between a tapered disc 46 and an annular protrusion of the dispenser body 45. A locking sleeve 44 is threaded into the dispenser body 45 and configured to push the tapered disc 46 onto the gripping ring 47 to secure the rear portion of the cylinder 1 within the connecting device. Figure 27A and Figure 27B As can be seen, the support structure 48 with this connecting device can have a length that is significantly shorter than that of the cylinder 1.

[0105] Alternatively, the base structure 48 can include a retractably extending frame having a dispenser body 45 and two side rods 49, each of the two side rods 49 being provided with a side rod notch 51 that can be engaged by a frame lock 50. With this configuration, cylinders 1 of different lengths can be securely held by the base structure 48, as by... Figure 28A and Figure 28B Instructions (and) Figure 28C and Figure 28D (Comparison). To adjust the base structure 48 to the length of a specific cylinder 1, the frame lock 50 is disengaged by movement in the direction Y indicated in Figure 28, and the side rod 49 is positioned relative to the distributor body 45 as shown in Figure 28. Figure 28C It is pushed in the direction indicated by X or in the opposite direction. Afterwards, the frame lock 50 re-engages with the side rod recess 51.

[0106] Regarding the base structure 48, it should be noted that it is typically configured such that the cylinder 1 can be fixedly but releasably connected to the base structure 48. In all the configurations shown, the plunger 3 is configured to translate into the cylinder 1, which is connected to the base structure 48, to dispense material from the cylinder 1. The movement of the cylinder 1 relative to the plunger 3 for dispensing material from the cylinder is not achieved with the developed configuration.

[0107] As described above, the dispensing device 100 can be provided with a guiding device, which is in the form of at least one clamshell 52 (e.g. Figure 30A and Figure 30B (as shown in the image), at least one low-friction plate 53 (such as...) Figure 31 (as shown in the image), at least one (especially multiple) low-friction inserts 54 (such as...) Figure 32 (as shown in the image), and / or at least one (especially multiple) rollers 55 (such as...) Figure 33 (as shown in the image) to prevent the drive component 4 from being lifted off the drive drum 5 when the reaction force acts on the plunger 3 during the dispensing operation, such as... Figure 29 It is displayed in the middle.

[0108] Finally, refer to Figures 34A to 34C The illustration shows an additional configuration of a manually driven dispensing device 100 for dispensing material from the 2k cylinder 1.

[0109] The dispensing device 100 includes two drive members 4, one for each cylinder 1. One of the drive members 4 (here, the one on the left) is provided around a threaded drive shaft 11, while the other drive member 4 (here, the one on the right) is provided around a non-threaded guide rod 58. A manually operable drive gear 59 is threadedly engaged with the threaded drive shaft 11 and abuts against a drive plate 57, which is provided with through holes for the threaded drive shaft 11 and the guide rod 58. A guide block 56 is provided to guide the dispensing movement of the two drive members 4.

[0110] In this configuration, the drive gear 59 can be manually rotated to cause it to move upward along the threaded drive shaft 11 (due to the threaded engagement of the two parts). This upward movement of the drive gear 59 pushes the drive plate 57 upward along the threaded drive shaft 11 and the guide rod 58 until it contacts the rear end of the drive member 4. As the drive gear 59 rotates further in the same direction, the drive plate 57 is caused to push the two drive members 4 upward into the guide block 56, and thus against the plunger 3 acting on the piston 2 to dispense material from the cylinder 1.

[0111] This configuration can also be implemented for a single cylinder 1, i.e., without the need to provide a second drive component 4, guide rod 58 and drive plate 57.

[0112] The configuration is suitable for all ratios of length to width of the cylinder, but is particularly suitable for ratios such as 10:1, where small springs can be used to compensate for the free space required to use a smaller cylinder 1.

[0113] The system can also use two threaded drive shafts 11, either with two matched drive gears 59 and opposite threaded drive shafts 11, or with an idler gear between the two drive gears 59 and the same thread direction for the drive gears 59.

[0114] Alternative guide blocks 56 or adjustable guide blocks may be available, allowing for different angles for the drive member 4. Guide block 56 can be replaced by rollers, low-friction pads, or combinations thereof to achieve the adjustability. Rollers and low-friction pads also allow for adjustment of the angle in the drive member by the user for different applications.
