[Technical field to which the invention belongs]
INDUSTRIAL APPLICABILITY The present invention is used when a water thread used for determining a level line or a reference line in construction work or civil engineering, i.e., a thread used for measuring a reference line or a carpenter, inscribes a column material or a plate material. The present invention relates to a bobbin winder for winding ink and the like.
[0002]
[Prior art]
Conventional spools for water and ink are used to wind the yarn by turning it with a handle, or to take up the yarn with the restoring force of the spring as the take-up reel rotates with the spring when unlocked. It has been known.
[0003]
[Problems to be solved by the invention]
However, the above-described type of winding the thread with the handle takes time for the winding operation, and the attachment member such as the handle protrudes to the outside, which is inconvenient for portable use. There was a problem. Further, in the latter type of winding method using the restoring force of the spring, when the yarn is pulled out, it must be pulled out against the elasticity of the spring, so there is resistance to the pulling operation and the yarn life is reduced by the tensile stress applied to the yarn. Deterioration is fast, and when the thread stopper needle at the end of the thread is stabbed into the target location and the thread is pulled out, the thread stopper is accidentally removed, or the thread stopper is inadvertently pulled back at once, causing injury by the needle. There was a harmful effect of doing.
[0004]
Therefore, the present invention can be operated with peace of mind because there is no tension for pulling back the thread when the thread is pulled out or being used, and the thread can be wound up easily and quickly simply by pressing the push type operation unit. The main purpose of the present invention is to provide a pincushion that can be used in a compact structure.
[0005]
In addition, the present invention can be drawn out in a state where ink is infiltrated and transferred to the yarn by adding a simple member to the bobbin for water yarn, that is, for measuring the reference line, so that the carpenter can pull out the column material. Another object of the present invention is to provide a bobbin that can be used as a brush for drawing a straight line on a sheet material.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention takes the following technical means. In other words, in the bobbin winder according to the present invention, the thread winding rotary drum 1 rotatably mounted in the frame A and the thread 2 formed on the tip of the frame A and wound around the rotary drum 1 are taken out.

[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. The bobbin shown in the embodiment is an embodiment relating to a bobbin for water yarn, that is, a bobbin for measuring a reference line. In the figure, reference numeral A denotes a frame, and as shown in FIGS. 1 and 2, the rotary drum 1 around which the thread 2 is wound is mounted so as to be rotatable and preferably detachable. . Further, a thread take-out port 3 for taking out the yarn 2 wound around the rotary drum 1 is provided at the front end of the frame A, and a thread stopper 4 connecting the front end of the yarn 2 is detachably attached to the thread take-out port 3. ing. The thread stopper 4 includes a needle 4a.
[0010]
Furthermore, a push type operation unit 6 that rotates the rotary drum 1 in the yarn winding direction, and a power transmission mechanism B that accelerates the pushing operation of the operation unit 6 and rotates the rotary drum 1 at a high speed in the yarn winding direction. Is provided. The operating portion 6 is constantly urged in the upward direction by a return spring 9. The power transmission mechanism B is formed as follows. That is, the rack 6a formed in the operation unit 6 meshes with the first small gear 10, and the first large gear 11 that rotates integrally coaxially with the small gear 10 is engaged with the second small gear 12. The second large gear 13 that meshes with the small gear 12 and rotates integrally with the small gear 12 is meshed with the third small gear 14 that rotates coaxially with the rotating drum 1. A common shaft 15 of the first small gear 10 and the large gear 11 is slidably mounted in a long hole 16 extending in the vertical direction, and the shaft 15 moves up and down along the long hole 16 so that the first shaft 15 moves up and down. The large gear 11 is formed so as to mesh with or disengage from the second small gear 12. Accordingly, when the operation unit 6 is pushed down from the state shown in FIG. 1, the first large gear 11 meshes with the second small gear 12 and simultaneously the gear group rotates to rotate the rotary drum 1 at high speed in the yarn winding direction. Conversely, when no pressing force is applied to the operating portion 6, the operating portion 6 is moved up together with the first small gear 10 and the large gear 11 by the return spring 9, and the first large gear is moved. 11 is disengaged from the second small gear 12.
[0011]
Further, as described above, when the rotary drum 1 rotates in the yarn take-out direction with the power transmission between the operation unit 6 and the rotary drum 1 released, the rotary drum 1 is lightly braked, and conversely the operation A braking means C is provided for releasing the braking when the part 6 is operated to rotate the rotary drum 1 in the yarn winding direction. The braking means C is formed as follows in this embodiment. That is, a disc 17 having a continuous corrugated surface is attached so as to rotate integrally coaxially with the rotary drum 1, and a brake shoe formed of an elastic metal wire on the corrugated peripheral surface of the disc 17. 18 is in elastic contact. The braking force by the brake shoe 18 is set to such an extent that the rotary drum 1 can rotate when the yarn 2 is pulled out. Further, one end of the brake shoe 18 is loosely fitted in a long hole 19 provided in the frame A as shown in FIG. 5, and the lower end of the return spring 9 is received at the end of the brake shoe 18. . In this case, the elasticity of the brake shoe 18 is set to be superior to the elasticity of the return spring 9 so that the brake shoe 18 is positioned at the upper part of the long hole 19, so that the brake shoe 18 is not operated when the operation unit 6 is not operated. The brake shoe 18 is in the braking position, and is formed such that the brake shoe 18 moves away from the disk 17 to the non-braking position when the operation unit 6 is pushed down.
[0012]
Further, a lock lever 8 for locking and unlocking the rotation of the rotary drum 1 is provided on the frame A. When the lock lever 8 is locked, the claw tip 8a engages with the waveform peripheral surface of the disk 17 that rotates integrally with the rotary drum 1, and the lock lever 8 is pushed and moved as indicated by the phantom line in FIG. It is formed so that it can be unlocked by releasing it from the corrugated peripheral surface.
[0013]
In addition, a pair of retaining needles 20 projecting outward are provided around the thread take-out port 3 of the frame A. As shown in FIG. 1, when the thread stopper 4 is attached to the thread take-out outlet 3, the stop needle 20 is disposed along the side surface of the thread take-out opening 3, and the tip of the stop needle 20 is the thread stopper 4. It is formed so as to be covered by the step 4b. This prevents the tip of the stop needle 20 from being exposed when not in use.
[0014]
The frame A is provided with a lid 22 that can be opened and closed with the pivot 21 as a fulcrum as shown in FIG.
[0015]
The reference line measuring bobbin configured as described above is used by fixing the thread stopper 4 at a target location, moving the frame A to pull out the thread 2 to a desired length, and fixing the frame A with the stopper needle 20. . Of course, the frame A can be used without being fixed. When the yarn 2 is pulled out, the rotary drum 1 is lightly braked by the braking means C. Therefore, when the yarn drawing operation is stopped, the rotary drum 1 stops without rotating due to inertia, and this causes the yarn to be doubled. This can be surely prevented.
[0016]
When winding the yarn 2, when the operating portion 6 is pushed down with the lock lever 8 released, the first large gear 11 meshes with the second small gear 12 and the gear group rotates. The brake shoe 18 is released from the disc 17 and the braking is released, and the rotary drum 1 can be lightly rotated at a high speed in the yarn winding direction, so that the yarn 2 can be quickly wound up. At this time, by pulling back while adjusting the pushing operation of the operation unit 6 and adjusting the winding degree of the yarn, it is possible to prevent the yarn stopper from being drawn at a stretch and to prevent the needle 4a from being injured. .
[0017]
6 and 7 can be used as a summoning tool for a carpenter to draw a straight line on a pillar material or a plate material by adding a simple member in addition to the configuration of the above-described reference line measuring bobbin. An embodiment as described above is shown.
[0018]
In this embodiment, the interior of the rotary drum 1 with the partition wall 1a therebetween is used as a tank storage portion 1b for storing the black ink tank 5, and the black ink tank 5 that rotates integrally with the rotary drum 1 in the tank storage portion 1b. Is detachably stored. The opening 2a of the black tank 5 and the black 7 in the tank are separated from the yarn 2 wound around the rotary drum 1 from the black tank 5 by the capillary phenomenon and the centrifugal force during rotation. Invasion and metastasis are made through a small hole 1c formed in the inner wall. In this embodiment, sponge, felt, non-woven fabric, or a mixed material thereof is used between the black tank 5 and the partition wall 1a of the rotary drum 1 as shown in FIG. A formed ink impregnating material 23 having an appropriate thickness is interposed. Further, the ink 7 in the ink tank 5 is not limited to the liquid, but the liquid may be impregnated in a ink impregnating material formed of sponge, felt, nonwoven fabric, or a mixed material thereof.
[0019]
Therefore, in the present embodiment, when the thread 2 is pulled out, the ink from the ink tank 5 is drawn out in a state where the thread is infiltrated and transferred to the thread. it can. In this case, in particular, there is no friction against the ink like the conventional ink brush, so that the yarn can be prevented from being damaged, and the ink tank and the rotating drum are hidden in the frame. Since the ink is drawn out in a state where the ink is infiltrated and transferred to the thread, it can be drawn in the same manner as when used horizontally or on an inclined surface.
[0020]
Although typical embodiments of the present invention have been described above, the present invention is not necessarily limited to the above-described embodiments. For example, the stop needle 20 provided on the frame A can be omitted. Further, when used as an ink striker, as shown in FIG. 7, it is preferable to provide a moisture absorbing cover 24 for absorbing ink scattered by the rotational centrifugal force of the rotary drum 1. By providing a means to absorb such scattered ink and prevent it from exuding to the outside, it is possible to prevent contamination of other objects during use and storage in a tool box, etc., and always be used in a beautiful state. There are advantages. In addition, in the present invention, it is needless to say that the present invention can be implemented with appropriate modifications within the range having the structural requirements and the effects.
[0021]
【The invention's effect】
Since the bobbin of the present invention is configured as described above, there is no tension for pulling back the thread when the thread is pulled out or being used, and it can be used with peace of mind while reducing the tensile stress applied to the thread. In addition, the yarn can be prevented from deteriorating, and the push-down motion is accelerated by the power transmission mechanism just by pushing the operating part, and is transmitted as rotational force in the yarn winding direction of the rotating drum, so that the yarn can be wound quickly. By adjusting the push operation of the operation unit, it can be pulled back while adjusting the winding speed of the thread, thus preventing the danger of the needle due to the thread stopper being pulled at a stretch. Can do. Further, when the rotating drum rotates in the yarn take-out direction, it is attached so as to rotate integrally coaxially with the rotating drum, and a disk having a continuous circumferential surface and a waveform circumferential surface of the disk. Because the brake is lightly braked by the braking means consisting of the brake shoes that are elastically contacted , when the yarn is pulled out to a predetermined length and stopped, the rotating drum prevents the yarn from being duped due to the inertia rotating excessively. On the contrary, when rotating in the yarn winding direction, the brake shoe is released from the disk, the braking is released, and the rotating drum can be rotated lightly. In addition, since members such as a rotating drum and a power transmission mechanism are housed in the frame, there are various remarkable effects such that the appearance can be made smart and compact.
[0022]
According to the configuration of claim 2, in addition to the above-described effect, the ink sucked from the ink tank when the thread is pulled out is drawn out in a state infiltrated and transferred to the thread. In this case, there is no friction against the ink meat like a conventional ink brush, so that the yarn can be prevented from being damaged and the ink tank can be used. Since the rotating drum is hidden in the frame, it is resistant to dryness and rain, and there is no ink leakage, and the ink is drawn out in a state where it has infiltrated and transferred to the thread. There is a remarkable effect that the line can be drawn unchanged.
