Description

Crescent-shaped refrigerant tube winding device for an auger-type ice maker's ice tube

[0001] The present invention relates to an auger-type ice maker, and more specifically, to a winding device for a crescent-shaped refrigerant tube of an ice maker's ice tube that automatically winds a crescent-shaped refrigerant tube so as to be tightly wound in a spiral manner on the ice maker tube.

[0002]

[0003] According to the prior art, the US Scotsman Ice Systems website https: / www.scotsman-ice.com (published in May 2011) discloses that, as shown in FIG. 1, a crescent-shaped refrigerant tube (2) (hereinafter also referred to as a refrigerant tube) is wound spirally around the outer surface of a circular ice-making tube (1), thereby increasing the contact area of ​​the refrigerant tube (2) with the ice-making tube (1), so that the thermal energy of the refrigerant circulating along the refrigerant tube (2) can be rapidly transferred to the ice-making tube (1).

[0004]

[0005] In addition, regarding the spiral winding of the refrigerant pipe (2) onto the ice-making pipe (1), as in Korean Registered Patent No. 10-2257413 (published May 31, 2021), the refrigerant pipe is first wound spirally using a jig, then the spiral refrigerant pipe is detached from the jig, and after inserting the ice-making pipe into the center of the separated spiral refrigerant pipe, pressure is applied to the spiral refrigerant pipe by rolling so that the spiral refrigerant pipe adheres to the outer surface of the ice-making pipe.

[0006]

[0007] However, when a jig is used to wind the spiral refrigerant tube, the wound tubes do not adhere closely to each other, resulting in gaps. Furthermore, when a separately manufactured spiral refrigerant tube is inserted into the ice-making tube and then pressurized by rolling, the tube is not pressurized entirely; instead, only the pressurized portion where the rolling passes adheres to the ice-making tube, causing the unpressurized portions to lift up.

[0008]

[0009] In other words, when one side of the spiral refrigerant tube is pressed by rolling, the other side, where no pressing force is applied, is lifted, and as a result, the spiral refrigerant tube does not partially adhere to the outer surface of the ice-making tube, causing a problem in which the heat conduction efficiency of the refrigerant is reduced.

[0010]

[0011] In addition, when a separately manufactured spiral refrigerant tube is inserted into the ice-making tube and then pressurized by rolling, there is a problem in that it leads to reduced productivity and increased manufacturing costs.

[0012]

[0013] The purpose of the present invention is to provide a crescent-shaped refrigerant tube winding device for an auger-type ice maker, which allows a crescent-shaped refrigerant tube to be wound spirally and closely around the outer surface of the ice maker tube.

[0014]

[0015] Another objective of the present invention is to improve productivity and reduce manufacturing costs by directly winding a crescent-shaped refrigerant tube spirally on the outer surface of the ice-making tube.

[0016]

[0017] The present invention includes a straightness correction means for straightening the refrigerant pipe and correcting twisting as the crescent-shaped refrigerant pipe, which is unwound and transported by a roll refrigerant pipe of a roll support, passes through a plurality of upper and lower rollers arranged in a zigzag state via a guide roller and a plurality of pairs of upper and lower rollers; a horizontal reciprocating movement means for enabling horizontal movement of the horizontal moving plate member and the ice-making pipe by the movement of a nut fastened to a screw shaft that receives power from a forward / reverse reduction motor fixed to a base, and a detachment member and a pressure rotating member that support the ice-making pipe on which the refrigerant pipe is wound, wherein the detachment member has a locking groove into which an inlet pipe of one side of the ice-making pipe is inserted and a detachment hole, and the detachment member is rotated by the power of the forward / reverse reduction motor; and on the other side of the ice-making pipe to which one side is attached to the detachment member, the detachment member is rotated by the power of the forward / reverse reduction motor. The invention is characterized by comprising a winding device part having a pressurized ice tube support means in which a pressurized rotating member is in close contact with the other side of the ice tube by the pneumatic pressure of a pneumatic cylinder to support the other side of the ice tube and enable it to rotate in tandem with the ice tube, and a cooling tube pressurizing means in which a pressurized wheel, which pressurizes a refrigerant tube transferred to the upper side of the outer surface of one side of the ice tube, is supported on a wheel base and moves vertically by the pneumatic pressure of the pneumatic cylinder, and wherein the leading end of the refrigerant tube transferred to the upper side of the outer surface of one side of the ice tube in the winding device part is tin-soldered to fix it to the ice tube, and then, while the refrigerant tube is pressurized by the pressurized wheel, the ice tube supported between the detachment member and the pressurized rotating member rotates and moves in one direction so that the refrigerant tube is wound spirally on the outer surface of the ice tube.

[0018]

[0019] Another feature is that the horizontal moving member is configured to move in a horizontal direction by providing a support moving guide that moves along a rail provided on the base, and to rotate by power from a forward / reverse reduction motor by providing a spindle on one side of the base with a detachable member fixed to one end, and to enable horizontal reciprocating movement by a pneumatic cylinder by providing a horizontal moving shaft member on the base fixed to the horizontal moving member on the opposite side facing the base, with a pressure rotating member mounted on one end.

[0020]

[0021] Another feature is that the wheel base supporting the above-mentioned pressure wheel is movable in a vertical direction by means of a pneumatic cylinder fixed to a horizontal movement frame that moves along a pair of guide rods fixed to a standing base, and a screw rod provided to stand upright on one side of the wheel base penetrates the horizontal movement frame to fasten a stopper nut, thereby allowing the distance the pressure wheel moves downward to be adjusted, and a setting stopper is provided on one side of the guide rod so that the horizontal movement frame can be stopped by being caught.

[0022]

[0023] The present invention has the effect of providing a crescent-shaped refrigerant tube winding device for an auger-type ice maker, which allows a crescent-shaped refrigerant tube to be wound spirally and closely around the outer surface of the ice maker tube, while also ensuring that the wound refrigerant tubes are closely together.

[0024]

[0025] Accordingly, the present invention has the effect of providing an auger-type ice maker with superior ice-making efficiency, as the heat transfer rate between the refrigerant tube and the ice maker is greatly improved by winding a crescent-shaped refrigerant tube tightly in a spiral shape around the outer surface of the ice maker tube, and also ensuring that adjacent refrigerant tubes are tightly wound together.

[0026]

[0027] Furthermore, since the present invention involves directly winding a crescent-shaped refrigerant tube spirally around the outer surface of the ice-making tube, it provides the effect of improving productivity and reducing manufacturing costs.

[0041]

[0042] The present invention includes a straightness correction means (10) that causes the refrigerant pipe (2) to straighten out and correct twisting as the refrigerant pipe (2) passes through a plurality of upper and lower rollers (11, 11') and a plurality of pairs of upper and lower rollers (12, 12'); a horizontal reciprocating movement means (22) that supports the ice-making pipe (1) on which the refrigerant pipe (2) is wound, and a pressure rotating member (44) is provided on the upper side of a horizontal moving plate member (23) to cause the horizontal moving plate member (23) and the ice-making pipe (1) to move horizontally; an ice-making pipe mounting rotation means (30) in which the refrigerant pipe (1) is coupled to one side of the ice-making pipe (1) and rotated by the power of a forward / reverse reduction motor (36); and a pressure rotating member (44) in close contact with the other side of the ice-making pipe (1). The invention includes a winding device part (20) having an ice-making pipe pressurizing support means (40) that supports the other side of the ice-making pipe (1) and allows it to rotate in tandem with the ice-making pipe (11), and a cooling pipe pressurizing means (50) that pressurizes a refrigerant pipe (2) transferred to the upper side of the outer surface of the ice-making pipe (1) and is supported on a wheel base (54) to move in a vertical direction. After tin-soldering (2c) the tip (2b) of the refrigerant pipe (2) on the outer surface of the ice-making pipe (1) in the winding device part (20), the ice-making pipe (1) is rotated and moved in one direction while the refrigerant pipe (2) is pressurized by the pressurizing wheel (55), thereby allowing the refrigerant pipe (2) to be wound spirally on the outer surface of the ice-making pipe (1).

[0043]

[0044] The present invention will be described in more detail below with reference to the attached preferred embodiments.

[0045]

[0046] Referring to FIG. 2, the present invention comprises a straightness correction means (10) that makes a refrigerant pipe (2) rolled into a roll shape into a straight pipe, and a winding device part (20) that makes the refrigerant pipe (2) wind onto an ice-making pipe (1).

[0047]

[0048] The refrigerant pipe (2) is a copper pipe made of copper material, and the roll refrigerant pipe (2a), which is wound in a roll shape, is placed on the roll support (3) and rotated around the rotation axis (4) to be unwound, and the refrigerant pipe (2) unwound in this way is transported to the straightness correction means (10) through the guide roller (5).

[0049]

[0050] As shown in FIG. 3, the straightness correction means (10) is configured such that a plurality of upper and lower rollers (11, 11') are arranged in a zigzag state and rotate, and as the refrigerant pipe (2) passes between these upper and lower rollers (11, 11'), the refrigerant pipe (2) is primarily straightened into a straight state.

[0051]

[0052] In addition, a plurality of upper and lower rollers (12, 12') are provided horizontally, and the refrigerant pipe (2) passes between the pair of upper and lower rollers (12, 12'), thereby causing the refrigerant pipe (2) to be secondarily straightened, so that the refrigerant pipe (2) that has passed through the straightness correction means (10) becomes in a state of very good straightness.

[0053]

[0054] The movement of the refrigerant pipe (2) may be achieved by causing the lower rollers (11, 12) to rotate with motor power (not shown) so that the refrigerant pipe (2) engaged between the upper and lower rollers (11, 12, 11', 12'), but in the present invention, the refrigerant pipe (2) is wound around the outer surface of the ice-making pipe (1) by the refrigerant pipe rotating, which will be described in detail later. The refrigerant pipe (2) can be moved in the straightness correction means (10) by the winding force of the refrigerant pipe (2) wound around the ice-making pipe (1).

[0055]

[0056] Accordingly, referring to FIG. 4, among a pair of upper and lower rollers (12, 12'), the lower roller (12') is supported by a support (13) and is provided in a rotatable state, and the upper roller (12) is guided by two support guides (14) and is provided to be rotatable by being supported by a vertical moving member (15) that can move in a vertical direction. The vertical moving member (15) is configured to move in an upward or downward direction by rotating the adjustment screw shaft (17) fastened to the nut piece (16) in a forward or reverse direction, thereby allowing the refrigerant pipe (2) passing between the upper and lower rollers (12, 12') to be pressurized by the upper roller (12) and the pressurizing force to be adjusted. The upper roller (11) described above may also be configured to have the same structure as the upper roller (12) to allow the refrigerant pipe (2) to be pressurized and the pressurizing force to be adjusted by the upper roller (12).

[0057]

[0058] And as shown in FIG. 5, it is preferable that the upper roller (11, 12, 11', 12') be provided with a crescent groove (18) on the outer surface of the roller and the lower roller (11', 12') be provided with a straight groove (19) so that the twisting of the crescent-shaped refrigerant pipe (2) is corrected.

[0059]

[0060] Referring to FIGS. 6 to 8, the winding device (20) is provided with a horizontal reciprocating movement means (22) configured such that a horizontal moving plate member (23) can reciprocate in the left and right directions in FIG. 6 along a long rail (24) that is fixedly provided on a lower support (21). Reference numeral 23a indicates a support moving guide (23a) that engages with the rail (24).

[0061]

[0062] In addition, as shown in FIGS. 8 and 9, the horizontal reciprocating means (22) is configured such that a screw shaft (26), which is rotated in forward and reverse directions by the power of a forward / reverse reduction motor (25) fixed to a support (21), is supported by a support (27) and can rotate, and a nut (28) fastened to the screw shaft (26) is configured to be connected to a horizontal moving plate member (23) by a connecting member (29).

[0063]

[0064] Accordingly, when the screw shaft (26) rotates forward as the forward / reverse reduction motor (25) rotates forward, the nut (28) moves to the right in Fig. 9, and the horizontal moving plate member (23) moves to the right. Conversely, when the screw shaft (26) rotates in reverse due to the reverse rotation of the forward / reverse reduction motor (25), the nut (28) moves to the left in Fig. 9, and the horizontal moving plate member (23) moves to the left.

[0065]

[0066] Meanwhile, on one side of the horizontal moving plate member (23), an ice-making pipe mounting rotation means (30) is provided, so that the ice-making pipe mounting rotation means (30) also moves back and forth by the reciprocating movement of the horizontal moving plate member (23).

[0067]

[0068] As shown in FIGS. 9 to 11, the ice-making tube mounting rotation means (30) is configured such that a spindle (32) is rotatably mounted on a support (31) which is fixedly mounted on the upper part of a horizontal moving plate member (23), and a detachable member (34) having a detachable hole (33) is integrally mounted on one end of the spindle (32) so that the detachable member (34) is also rotated by the rotation of the spindle (32), and a locking groove (35) is provided on one side of the detachable hole (33).

[0069]

[0070] Additionally, as shown in FIG. 9, a forward / reverse reduction motor (36) is fixedly provided at the bottom of the horizontal moving plate member (23). However, the forward / reverse reduction motor (36) may also be fixed at the bottom of the support (31). The spindle (32) is configured to rotate by the power of the forward / reverse reduction motor (36). It is preferable that the power of the forward / reverse reduction motor (36) be transmitted to the spindle (32) using the belt (37) and pulley (37') shown in FIG. 11.

[0071]

[0072] As shown in FIG. 10, the ice making tube (1) is configured such that an inlet pipe (1a) protrudes to one side to allow water to enter the ice making tube (1). The present invention uses the inlet pipe (1a) of the ice making tube (1) to insert one end of the ice making tube (1) into the detachment hole (33) of the detachment hole (34) and to insert the inlet pipe (1a) into the catch groove (35). When the detachment hole (34) is rotated by the rotation of the spindle (32), the inlet pipe (1a) is caught in the catch groove (35), so the ice making tube (1) is in a state of rotation.

[0073]

[0074] Meanwhile, the horizontal moving plate member (23) on the side opposite to the ice-making pipe mounting rotation means (30) is configured to have an ice-making pipe pressurizing support means (40) to which a support (41) is fixed.

[0075]

[0076] As shown in FIGS. 8 and 9, the base (41) of the ice-making pipe pressurizing support means (40) is provided with a horizontal movement shaft member (42) that can move back and forth in a horizontal direction, and the horizontal movement shaft member (42) is directly connected to the piston rod (43a) of a pneumatic cylinder (43) fixed to one side of the base (41), so that the horizontal movement shaft member (42) moves back and forth by the reciprocating movement of the piston rod (43a).

[0077]

[0078] Additionally, a pressure rotating member (44) configured to rotate while applying pressure to one end of the ice-making pipe (2) is provided at one end of the horizontal moving shaft member (42). Depending on the diameter of the ice-making pipe (1), the pressure rotating member (44) may be adopted with a large size or diameter as shown in FIG. 6, or with a relatively small size or diameter as shown in FIG. 9, and may be used interchangeably.

[0079]

[0080] Accordingly, when the piston rod (43a) moves forward in the right direction in Fig. 9 by operating the pneumatic cylinder (43) while the end of the ice-making tube (1) is mounted on the detachment member (34) as shown in Fig. 9, the horizontal movement shaft (42) also moves in the right direction. As a result, the pressure rotating member (44) comes into close contact with the other end of the ice-making tube (1) as shown by the dashed line in Fig. 9, thereby pressurizing the ice-making tube (1). Consequently, the ice-making tube (1) maintains a horizontal state and does not detach from the detachment member (34). In this state, when the ice-making tube (1) rotates due to the rotation of the detachment member (34), the pressure rotating member (44) rotates simultaneously, allowing the ice-making tube (1) to continuously maintain a horizontal state while rotating.

[0081]

[0082] And when the ice-making tube (1) is released, the piston rod (43a) moves backward to the left in Fig. 9 by operating the pneumatic cylinder (43), and the horizontal movement shaft (42) also moves to the left, so that the pressure rotating member (44) is detached from the other end of the ice-making tube (1) as shown by the solid line in Fig. 9, and in this state, the ice-making tube (1) is pulled out from the detachment port (34) and separated.

[0083]

[0084] Meanwhile, the present invention is provided with a refrigerant pipe pressurizing means (50) on the upper side of the winding device part (20).

[0085] Referring to FIGS. 6 to 9, the refrigerant pipe pressurizing means (50) is provided with a pair of guide rods (51) between a pair of standing stands (21') that are fixed to stand upright on a stand (21), and a horizontal moving frame (52) that moves horizontally along the guide rods (51).

[0086]

[0087] Additionally, a pneumatic cylinder (53) is mounted on the horizontal moving frame (52), and a wheel base (54) is provided at the end of the piston rod (not shown) of the pneumatic cylinder (53), and a pressure wheel (55) having a crescent groove (55a) on its outer surface is provided on one side of the wheel base (54) so ​​as to be rotatable.

[0088]

[0089] And a screw rod (56) is configured to pass through one side of the horizontal moving frame (52) so that it can move in the up and down direction, and the lower end of the screw rod (56) is fixed to the wheel base (54), and a stopper nut (57) is fastened to the screw rod (56) that protrudes toward the upper side of the horizontal moving frame (52), so that when the wheel base (54) moves downward by operating the pneumatic cylinder (53), the screw rod (56) also moves downward at the same time. At this time, if the stopper nut (57) is rotated to move from position "a" to position "b" in FIG. 9, it moves downward only by the distance moved, and the stopper nut (57) moved to position "b" is caught on the horizontal moving frame (52) and stops.

[0090]

[0091] And the present invention is configured to have a setting stopper (58) that moves along the longitudinal direction along the guide rod (51) and is fixed to the guide rod (51) by a fixing screw (58a), so that when the horizontal moving frame (52) in FIG. 9 is moved to the setting stopper (58) and the horizontal moving frame (52) is caught on the setting stopper (58), the pressure wheel (55) is set to a position where it pressurizes the refrigerant pipe (2).

[0092]

[0093] Accordingly, when the pneumatic cylinder (53) is operated and the piston rod (not shown) moves downward, the pressure wheel (55) moves downward together with the wheel base (54), thereby causing the refrigerant pipe (2) placed on the upper outer surface of the ice-making pipe (1) to be inserted into the crescent groove (55a) and the refrigerant pipe (2) to be pressurized by the pressure wheel (55).

[0094]

[0095] Referring to FIG. 12, the present invention fixes the tip (2a) of the refrigerant pipe (2), which is placed on the upper outer surface of the ice-making pipe (1) at the beginning of operation, to the ice-making pipe (1) by tin soldering (or soldering) (2c), and then as the ice-making pipe (1) rotates and moves slowly to the right in FIG. 12, the refrigerant pipe (2) is wound spirally on the outer surface of the ice-making pipe (1).

[0096]

[0097] At this time, the pressure wheel (55) is in a state of only rotating (revolution) while stationary in place, and as the ice-making tube (1) rotates and moves to the right, the refrigerant tube (2) is wound spirally on the outer surface of the ice-making tube (1), thereby obtaining an ice-making tube (1) with a crescent-shaped refrigerant tube (2) wound spirally as shown in FIG. 13.

[0098]

[0099] Accordingly, in the present invention, since the refrigerant pipe (2) is directly wound onto the ice-making pipe (1), the refrigerant pipe (2) does not become loose as in the conventional method, and the crescent-shaped refrigerant pipe (2) can be closely attached to the outer surface of the ice-making pipe (1), thereby enabling good heat transfer from the refrigerant pipe (2) to the ice-making pipe (1).

[0100]

[0101] The present invention is not necessarily limited to what is depicted and described in the drawings, and since it can be modified and implemented in various forms by those skilled in the art to which the invention pertains, it is obvious that it should be broadly protected as long as it does not significantly deviate from the scope of the claims.

[0102]

[0103] The present invention is configured such that a crescent-shaped refrigerant pipe (2) is straightened and twisted, and then one side of the ice-making pipe (1) is supported by a detachable member (34), and a pressure rotating member (44) is attached to the other side of the ice-making pipe (1) to support the other side of the ice-making pipe (1). After soldering and fixing the refrigerant pipe (2) to the outer surface of one side of the ice-making pipe (1), the pressure wheel (55) pressurizes the refrigerant pipe (2) while rotating, causing the ice-making pipe (1) to move to one side simultaneously with rotation, thereby enabling the refrigerant pipe (2) to be automatically wound spirally on the outer surface of the ice-making pipe (1). This configuration allows the refrigerant pipe (2) to be directly wound on the ice-making pipe (1). This invention can be used not only in ice-making machines but also in water heaters, etc., where a copper pipe is wound on the outer surface of a water circulation tank.
