Description

    The present invention relates to a spring separating apparatus that makes it easy to handle a spring by disassembling a set of intertwined springs in a spring mainly composed of a coil spring.

  In general, for example, when coil springs are manually assembled to various devices, a set of springs put in a storage box or bag is taken out and placed on a tray, and the springs are separated and assembled one by one from the set. To. At this time, since the springs are in an intertwined state in the set of springs, they are separated by manually disassembling and separating them and arranging them on a tray, etc. Work is cumbersome and impairs work efficiency. For this reason, conventionally, a spring separation device that separates the springs by separating them is used.

Conventionally, as this type of spring separation device, for example, one disclosed in Japanese Patent Laid-Open No. 2006-69797 (Patent Document 1) is known.
As shown in FIG. 8, the separation device Ta includes a container 100 having an inlet 101 and an outlet 102 of a spring (not shown) and capable of accommodating a set of springs inserted from the inlet 101. The spring that has been unwound by unraveling the spring can be discharged from the outlet 102. The lower end surface of the container 100 is provided with a rotating plate 104 provided with a protrusion 103 on the upper surface. A protrusion 105 is also provided on the inner surface of the container 100.

By the way, in the separation device of the type in which the conventional motor 106 is rotated to unwind the spring by the projections 103 and 105 inside, or the separation device of the type to unwind the spring by blowing air, the rotation mechanism or the air injection Since the apparatus has to be provided, there is a problem that the apparatus is complicated and the cost is increased.
The present invention has been made in view of the above problems, and provides a spring separating device that has a simple structure, is easy to operate, and can be easily unwound and separated to reduce costs. Objective.

In order to achieve the above object, a spring separating apparatus of the present invention comprises a container having an inlet and an outlet of a spring and capable of accommodating a set of springs inserted from the inlet, and the spring is entangled in the container. In the spring separating apparatus, in which the uncoiled spring can be discharged from the outlet,
When the container has the inlet at one end and the outlet at the other end, the spring is inserted from the inlet toward the outlet when the inlet is on the upper side and the outlet is on the lower side. A plurality of tongue pieces that are formed in a cylindrical shape that can be freely dropped and that have a proximal end supported on the inner surface side of the container and that can be contacted by a spring with a distal end extending downwardly are provided. Provided with a space through which the container can pass, and by reciprocating the container along the central axis direction, the tongue pieces are elastically supported so as to be swingable with the base ends of the tongue pieces as fulcrums . It is configured.

  Thus, for example, when assembling the springs one by one from a set of springs put in a storage box or bag, for example, when assembling the springs manually on various devices, To do. First, an appropriate amount of the spring assembly is put into the container from the inlet of the container. Then, with the inlet of the container facing up and the outlet facing down, the container is held with one hand, for example, and shaken in the direction of the central axis to reciprocate. As a result, the spring moves up and down to come into contact with the tongue piece, and the tongue piece itself also oscillates, so that an impact is repeatedly applied to the spring. Therefore, the entangled springs are unwound, fall from the interval between the tongue pieces, and are discharged from the outlet. If the discharged springs are arranged on a table or the like, the work of assembling the springs one by one to various devices can be easily performed. In this case, since the spring can be easily entangled and separated by a simple operation by simply shaking the container, workability can be greatly improved. Further, since it is not necessary to rotate the motor or blow in air as in the prior art, the structure is extremely simple, the device itself can be made compact, and the cost can be reduced.

  In the present invention, it is effective to form each of the plurality of tongue pieces with an elastically deformable spring member. Since the tongue piece itself is elastically deformed, it is possible to give a repeated impact to the spring even by this deformation, and the separation efficiency can be improved.

  In addition, it is effective that each of the plurality of tongue pieces is bent into a corrugated shape in which peaks and valleys are alternately continued along the longitudinal direction. Since it is formed in a corrugated shape, the tongue piece is uneven, so that the chance of colliding with the tongue piece of the spring increases, and the separation efficiency can be further improved.

  Furthermore, it is effective to form the top of the peak at an acute angle. The mountain portion easily enters the gap between the springs, so that it is easy to separate, and in this respect, the separation efficiency can be further improved.

  Furthermore, it is effective that the tip portions of the plurality of tongue pieces are inclined toward the central axis. Since the tip is inclined, the spring can be easily repelled and the spring can be smoothly dropped.

  In addition, it is effective to provide the base ends of the plurality of tongue pieces at equal intervals along one inner peripheral line on a plane orthogonal to the central axis. It becomes easy to receive a set of springs, and when the container is shaken up and down, the chance of collision with the tongue piece can be surely ensured, and the separation efficiency can be further improved.

  It is also effective to provide a frame attached along the inner periphery of the container, and to provide the base ends of the plurality of tongue pieces at equal intervals on the frame. Since the device can be manufactured simply by attaching a tongue piece to the frame in advance, and attaching the frame to the container by fitting it, etc., the manufacturing can be facilitated. Cost can be reduced.

  Further, each of the plurality of tongue pieces is formed to have the same length and the whole tongue piece is inclined downward, and one or several springs are surrounded by the tips of all or some of the plurality of tongue pieces. It is the structure which formed the passage which can pass. The spring separated from the gap between the tongue pieces can be dropped, and can also be dropped from the central passage. In this case, since the passage is large enough to allow one or several springs to pass therethrough, the whole tongue piece can receive the spring and can be dropped little by little, so that it can be reliably separated and discharged. it can.

Further, a receiving plate for receiving a spring inserted from the inlet is provided on the upper side of the tongue piece, and the receiving plate has a central portion for receiving the spring and an opening area smaller than the inlet formed around the central portion. It is effective to have a plurality of passage openings . Since the set of springs falls into the tongue piece from a plurality of passage openings, the spring is not clogged and can be reliably separated as compared with a case where it falls onto the tongue piece at a time. .

  Furthermore, the container is formed in a cylindrical shape, one end opening is configured as an inlet, the other end is formed in a funnel shape around the central axis, and the other end is an outlet through which one or several springs can pass. It is effective to configure as The springs can be discharged almost one by one from the outlet, and the subsequent processing can be facilitated.

  It is also effective to provide a lid that opens and closes the inlet. When the container is shaken, it is possible to prevent the spring from jumping out from the inlet.

  Further, the container is grasped with one hand so that the container can be reciprocated along the central axis, and a cloth cover for covering the container is provided. It can be easily held, and the appearance quality can be improved.

  According to the present invention, the container is shaken in the direction of the central axis and reciprocated to move the set of springs up and down to bring the spring into contact with the tongue piece, and the tongue piece itself also swings. So that the entangled spring can be unwound and discharged from the outlet. Therefore, the spring can be easily entangled and separated by a simple operation by simply shaking the container, so that workability can be greatly improved. Further, since it is not necessary to rotate the motor or blow in air as in the prior art, the structure is extremely simple, the device itself can be made compact, and the cost can be reduced.

Since the cloth covers 8 and 9 are provided, it can be easily held and the appearance quality can be improved.

As shown in FIGS. 2 to 4, 6, and 7 (b), the container 1 can come into contact with a spring S whose base end is supported on the inner side of the container 1 and whose distal end extends downward. A plurality of tongue pieces 10 are provided. The plurality of tongue pieces 10 are provided with an interval through which the spring S can pass , and each base end 11 of each tongue piece 10 is moved by reciprocating the container 1 along the central axis P direction. As a fulcrum, each tongue piece 10 is elastically supported in a swingable manner. Specifically, each of the plurality of tongue pieces 10 is formed of an elastically deformable spring member. In the embodiment, the tongue pieces 10 are formed of a thin plastic plate. Further, each of the plurality of tongue pieces 10 is formed into a wave shape in which crests 12 and troughs 13 are alternately continued along the longitudinal direction. Furthermore, the top part of the peak part 12 is formed at an acute angle. Furthermore, the tip portions 14 of the plurality of tongue pieces 10 are inclined toward the central axis P.

  Further, the base ends 11 of the plurality of tongue pieces 10 are provided at equal intervals along one inner peripheral line Q on a plane orthogonal to the central axis P. Specifically, a plastic frame 15 attached along the inner periphery of the container 1 is provided, and the base ends 11 of the plurality of tongue pieces 10 are integrally provided at equal intervals on the frame 15. The frame 15 is fixed to the inner surface of the container 1 with, for example, an adhesive. Further, the plurality of tongue pieces 10 are formed to have the same length, and each tongue piece 10 is inclined downward as a whole, surrounded by the tip of all or a part of the tongue pieces 10, and 1 of the spring S. One to several passages 16 are formed.

  Specifically, as shown in FIG. 4, a plurality of groups of a plurality of tongue pieces 10 provided with a base end 11 along one inner peripheral line Q are provided, and the base ends 11 of the tongue pieces 10 are provided in adjacent groups. The phase of the position is shifted. In the embodiment, two groups are provided. In one group G1, a plurality of tongue pieces 10 (A) are formed to have the same length, and each tongue piece 10 (A) is inclined downward as a whole, and each tongue piece 10 (A) The tip 16 forms a passage 16 which is surrounded by the tip and through which one or several springs S can pass.

In another adjacent group G2, a plurality of tongue pieces 10 (B) having the same number and the same length as one group G1 are provided, and each of the plurality of tongue pieces 10 (B) is provided for each group G1. The phase is shifted by (1/2) P, where P is the circumferential pitch between the tongue pieces 10 (A) of one group G1. In this case, since the device can be produced simply by preparing the tongue piece 10 on the frame 15 in advance and attaching the frame 15 to the container 1 by adhering it to the container 1, the manufacturing is facilitated. And cost reduction can be achieved.

In the container 1, as shown in FIGS. 2, 3, 5, 6, and 7 (a), on the upper side of the tongue piece 10, a plastic receiver that receives a spring S inserted from the inlet 2. A plate 20 is provided. A plurality of passage openings 21 having an opening area smaller than that of the inlet 2 are formed in the receiving plate 20. In the embodiment, the backing plate 20 is formed in a cup shape having a bottom wall 22 and an upward side wall 23, and the side wall 23 and a part of the bottom wall 22 continuous thereto are equiangularly spaced (90 in the embodiment). The cut portion of the bottom wall 22 is configured as a passage port 21. A central portion 24 of the bottom wall 22 is formed to bulge upward. And the side wall 23 is attached to the inner periphery of the container 1, and it adheres with the adhesive agent etc. That is, the receiving plate 20 includes a central portion 24 that receives the spring S, and a plurality of passage openings 21 that are formed around the central portion 24 and have an opening area smaller than the inlet 2.

Therefore, when the spring separation device T according to the embodiment of the present invention is used, for example, when the spring S is manually assembled to various devices, the spring S is collected from a set of the springs S placed in a storage box or a bag. When separating and assembling one by one, do as follows.
First, as shown in FIGS. 1A and 6, an appropriate amount of a set of springs S is put into the container 1 from the inlet 2 of the container 1. Then, the inlet 2 of the container 1 is closed with a lid 5.

  In this state, as shown in FIG. 1B, the container 1 is held with one hand, for example, with the inlet 2 facing up and the outlet 3 facing down, and is swung in the direction of the central axis P to reciprocate. In this case, since the lid 5 for opening and closing the inlet 2 is provided, it is possible to prevent the spring S from jumping out from the inlet 2 when the container 1 is shaken. As shown in FIGS. 6 and 7A, a receiving plate 20 that receives the spring S inserted from the inlet 2 is provided on the upper side of the tongue piece 10, and the receiving plate 20 has an opening smaller than the inlet 2. Since a plurality of passage openings 21 having an area are formed, the spring S moves up and down by the reciprocation of the container 1, and is subdivided from the plurality of passage openings 21 and falls onto the tongue piece 10. Therefore, the spring S is prevented from being clogged as compared with a case where the tongue piece 10 is dropped at a time, and the following separation can be reliably performed.

  6 and 7B, the spring S that has passed through the passage port 21 moves up and down by the reciprocating motion of the container 1, contacts the tongue piece 10, and the tongue piece 10 itself also swings. Therefore, an impact is repeatedly applied to the spring S. As a result, the tangled springs S are unwound, and the entire tongue pieces 10 are inclined downward, so that the springs S separated from the gaps between the tongue pieces 10 fall, and also from the central passage 16. It goes down and is discharged from the exit 3.

  In this case, since each of the plurality of tongue pieces 10 is formed of a spring member that can be elastically deformed, the tongue piece 10 itself is also elastically deformed. Separation efficiency can be improved. Further, since each of the plurality of tongue pieces 10 is formed in a corrugated shape in which the peak portions 12 and the valley portions 13 are alternately continuous, the tongue pieces 10 are uneven. The chance of collision increases, and the separation efficiency can be further improved. Furthermore, since the top part of the peak part 12 is formed at an acute angle, the peak part 12 easily enters the gap of the spring S, so that it is easy to separate, and in this respect, the separation efficiency can be further improved. . Further, since the tip portions 14 of the plurality of tongue pieces 10 are inclined toward the central axis P, the spring S can be easily repelled, and the spring S can be smoothly dropped.

  In particular, each of the plurality of tongue pieces 10 has base ends 11 provided at equal intervals along one inner peripheral line Q on a plane orthogonal to the central axis P, so that it is easy to receive a set of springs S. Moreover, when the container 1 is shaken up and down, the chance of collision with the tongue piece 10 can be ensured reliably, and also in this respect, the separation efficiency can be improved. Further, since the upper group G1 and the lower group G2 of the tongue piece 10 are provided, the spring S dropped from between the tongue pieces 10 (A) of the previous group G1 is moved to the tongue piece 10 ( B), the spring S can be impacted here as well, so that the spring S can be made to collide with the tongue piece 10 and be separated in a stepwise manner, so that the separation efficiency can be improved. . Further, since the passage 16 formed by the upper group G1 is large enough to allow one or several springs S to pass therethrough, the whole tongue piece 10 (A) receives the set of springs S and can be dropped little by little. Therefore, the spring S can be reliably separated and discharged. Furthermore, since the other end side of the container 1 is formed in a funnel shape, the springs S can be discharged almost one by one from the outlet 3, and the subsequent processing can be facilitated.

  If the discharged springs S are arranged on a table or the like, the operation of assembling the springs S one by one to various devices can be easily performed. As described above, according to the separation apparatus T, the entanglement of the spring S can be easily removed and separated by a simple operation of simply shaking the container 1, so that workability can be greatly improved. Further, since it is not necessary to rotate the motor or blow in air as in the prior art, the structure is extremely simple, the device itself can be made compact, and the cost can be reduced.

  In the above embodiment, each tongue piece 10 (A) of one group G1 and each tongue piece 10 (B) of the other group G2 are provided along the same inner peripheral line Q. However, the present invention is not necessarily limited thereto, and may be provided along the inner circumferential line Q at different positions in the vertical direction, and may be appropriately changed. Of course, three or more groups may be provided. Furthermore, in the above-described embodiment, the way of providing the tongue piece 10 is not limited to the above-described structure, and may be appropriately changed, for example, by protruding from the inner surface of the container 1 at random.

The present invention is not limited to the above-described embodiments of the present invention, and those skilled in the art will make many modifications to these illustrative embodiments without substantially departing from the novel teachings and advantages of the present invention. And many of these modifications are within the scope of the present invention.
