Guiding elements 69 is fixed on axle 68 leading section.Guiding elements 69 is configured on rear side of orbit portion 76.As shown in Figure 7, guiding elements 69 is in left apparent time in roughly letter C shape, and it extends in left-right direction.Guiding elements 69 comprises counterpart 61 and a pair clamping part 62.Counterpart 61 shape in the form of a substantially rectangular when backsight, it is relative with the rear surface of orbit portion 76 at the rear of the rear surface of orbit portion 76.Counterpart 61 is fixed on axle 68 leading section.A pair clamping part 62 is forwards given prominence to from the upper end of counterpart 61 and bottom respectively.A pair clamping part 62 has the protuberance 62A outstanding to direction close to each other at respective fore-and-aft direction central portion respectively.The multiple balls 56 arranged in left-right direction are remained on the position of the above-below direction central portion side by counterpart 61 of the respective base end part of a pair clamping part 62 by guiding elements 69 in the mode that can rotate.The multiple balls 59 arranged in left-right direction are remained on each protuberance 62A in the mode that can rotate by guiding elements 69.Multiple ball 56,59 is in same shape.By making each groove portion 76B in each protuberance 62A injection portion 76, thus multiple ball 59 is connected to each groove portion 76B, and multiple ball 56 is connected to the bight of the back upper place of orbit portion 76 and the bight of the back lower place.Therefore, guiding elements 69 and orbit portion 76 are connected.A pair clamping part 62 mode of movement in left-right direction can guide this orbit portion 76 with orbit portion 76.Rotated by multiple ball 56,59, thus orbit portion 76 can move relative to guiding elements 69 swimmingly in left-right direction.
With reference to Fig. 4, Fig. 5, the overview of the action of cloth-feeding device 10 is described.First, the action that cloth-feeding device 10 makes cloth move back and forth in left-right direction is described.When X-axis motor 31 drives, driving shaft 32 rotates, and left side spin rotating shaft 34 is rotated because pinion is meshed with gear 33.Because left side spin rotating shaft 34 is rotated, therefore left pulley 36 rotates.When left pulley 36 rotates, endless belt 29 is advance in clockwise direction or counterclockwise direction when side-looking, thus right side belt wheel 38 rotates.Along with advancing of endless belt 29, X-axis mobile member 40 moves back and forth in left-right direction along a pair X-axis trapped orbit 24,25.Therefore, Y-axis mobile member 73 and cloth holder 50 move back and forth in left-right direction.When cloth holder 50 moves back and forth in left-right direction, orbit portion 76 moves back and forth (with reference to Fig. 8, Fig. 9) in left-right direction relative to guiding elements 69.That is, when cloth holder 50 moves back and forth in left-right direction, orbit portion 76 changes relative to guiding elements 69 relative position in the lateral direction.Below, when the either end of cloth holder 50 in the left and right directions both ends of orbit portion 76 being contacted with guiding elements 69, on left and right directions position is called end position (with reference to Fig. 8), by cloth holder 50 when the left and right directions central portion of orbit portion 76 contacts with guiding elements 69, position on left and right directions is called middle position (reference Fig. 9).In this example, when cloth holder 50 is in end position, the left part of orbit portion 76 contacts with guiding elements 69.
The action that cloth-feeding device 10 makes cloth move back and forth along the longitudinal direction is described.When Y-axis motor 65 drives, driving shaft 66 (with reference to Fig. 5) rotates.Because driven wheel is meshed with the teeth portion 67 of axle 68, therefore axle 68 is moved back and forth along the longitudinal direction by driving.Because the axle 68 moved back and forth by driving moves back and forth along the longitudinal direction by guiding elements 69 drive track portion 76.Therefore, cloth holder 50 moves back and forth along the longitudinal direction with Y-axis mobile member 73 (with reference to Fig. 5).Further, Y-axis mobile member 73 moves back and forth along a pair Y-axis trapped orbit 51,52 along the longitudinal direction relative to X-axis mobile member 40.
Cloth-feeding device 10 intermittently drives X-axis motor 31 and Y-axis motor 65 in the mode synchronous with the driving of main motor.Therefore, cloth holder 50 repeat at short notice along left and right directions and fore-and-aft direction movement and stop the action of movement.Cloth-feeding device 10 make by the cloth kept by press box 84 and gripper frame 87 on workbench 5 intermittently to move back and forth with fore-and-aft direction in left-right direction with the synchronous mode that moves up and down of eedle.Therefore, Sewing machines 1 forms the needle tracking of regulation on cloth.
With reference to Fig. 8, Fig. 9, the fixed component 70 when the rigidity relative to fore-and-aft direction of the fixed component 70 when being in end position to cloth holder 50 and cloth holder 50 are in middle position relative to fore-and-aft direction rigidity between difference be described.In the following description, the left and right directions central portion of orbit portion 76 is called central portion 76C, the left part of orbit portion 76 is called left part 76D.The diagram by press box 84, gripper frame 87, two orbit portions 82 and two linking parts 83 is eliminated in Fig. 8, Fig. 9.When cloth holder 50 is in end position, axle 68 is partial to left side for arm 81.Therefore, when (arrow A direction) moves back and forth the left part 76D in axle 68 drive track portion 76 along the longitudinal direction, the left and right directions central portion of extended portion 74 with the left part 76D of orbit portion 76 for fulcrum bends in front-rear direction.That is, fixed component 70 is lower relative to the rigidity of fore-and-aft direction.When axle 68 is partial to right side for arm 81 too.
When cloth holder 50 moves to middle position from end position, axle 68 and arm 81 are located along the same line.Therefore, compared with when being in end position with cloth holder 50, the central portion 76C in axle 68 drive track portion 76 is when (arrow B direction) moves back and forth along the longitudinal direction, rising to some extent relative to the rigidity of fore-and-aft direction of fixed component 70.But because the central portion 76C of orbit portion 76 separates relative with gap with the central portion of extended portion 74, therefore, the ascending amount of the rigidity relative to fore-and-aft direction of fixed component 70 is lower.That is, even if cloth holder 50 position in the lateral direction changes, also not easily changing relative to the rigidity of fore-and-aft direction of fixed component 70.
Cloth-feeding device 10 intermittently drives X-axis motor 31 and Y-axis motor 65 according to the stitch data that the control part of Sewing machines 1 stores.Driven by Y-axis motor 65, thus axle 68 intermittently drives fixed component 70 to move back and forth.Cloth holder 50 repeats movement in the longitudinal direction at short notice and stops the action of movement.Fixed component 70 is subject to the effect of inertia force.When the left and right directions central portion of extended portion 74 bends in front-rear direction, the position of retaining member 90 offsets.Therefore, the cloth that retaining member 90 keeps can not be parked in ideal position, possibly cannot form the needle tracking of expectation.But, in the present embodiment, even if cloth holder 50 position in the lateral direction changes, fixed component 70 also not easily produce deviation relative to the rigidity of fore-and-aft direction.Therefore, the amount of bow of extended portion 74 can not realize stabilisation by extended portion 74 position influence in the lateral direction.Therefore, produce along with the bending of extended portion 74, retaining member 90 departure in the longitudinal direction realizes stabilisation.Because departure realizes stabilisation, therefore, the side-play amount between the actual stop position of cloth and desirable stop position realizes stabilisation.Therefore, easily according to side-play amount, correction is carried out to skew.As long as operator keeps the regulation compensating value based on side-play amount, Sewing machines 1 just can reduce the possibility of the needle tracking that cannot form expectation.
With reference to Figure 10 ~ Figure 12, the method for adjustment of retaining member 90 relative to the fixed position of fixed component 70 is described.When cloth holder 50 to be fixed on Y-axis mobile member 73 (with reference to Fig. 5) and cloth holder 50 to be linked up with guiding elements 69 by operator, sometimes because the assembly error etc. formed between the scale error of the various components of cloth holder 50, component causes frame support 96 and departs from tram by press box 84.At frame support 96 with when being positioned at tram by press box 84, the arm 81 of cloth holder 50 extends along the longitudinal direction.The example of the retaining member 90 that arm 81 self-retaining component 70 extends to right front has been shown in Figure 10, Figure 11.Frame support 96 and by press box 84 be partial to for tram right side.In fig. 11, represent frame support 96 when being in tram with double dot dash line respectively and by press box 84, and respectively indicated by the solid line deviate from tram frame support 96 and by press box 84.When frame support 96 with when departing from tram by press box 84, the motion track of cloth can depart from ideal trajectory, thus cannot form the needle tracking of expectation.
Four screw members 46 are unscrewed by operator.As shown in figure 12, head 46B leaves spring washer 48 upward.Retaining member 90 can and the amount in gap between through hole 41 and bar portion 46A correspondingly move.As shown in Figure 10, Figure 11, operator makes retaining member 90 rotate along horizontal direction along direction clockwise when overlooking (arrow C direction) relative to fixed component 70.Retaining member 90, while slide relative to the upper surface 72A (with reference to Fig. 6) of support 72, rotates.Frame support 96 and turn to tram by press box 84.Retaining member 90 by fastening for four screw members 46, is fixed on fixed component 70 by operator again.Therefore, operator can adjust the fixed position of retaining member 90 relative to fixed component 70 in the horizontal direction.The motion track of the cloth of cloth-feeding device 10 movement is consistent with desirable motion track.
In the above description, enumerate arm 81 to extend to the direction tilted relative to fore-and-aft direction, therefore operator makes the example that retaining member 90 rotates, but, when under the state extended along the longitudinal direction at arm 81, the position of retaining member 90 from tram along the longitudinal direction or left and right directions skew time be also same.As long as four screw members 46 are unscrewed by operator, and by retaining member 90 along the longitudinal direction or left and right directions move.
As mentioned above, four screw members 46 are unscrewed by operator, adjust the fixed position of setting unit 92,94 relative to fixed component 70 of retaining member 90 in the horizontal direction.That is, cloth holder 50 has four screw members, 46, four through holes 41 and four fastener holes 42, thus can adjust the fixed position of retaining member 90 relative to fixed component 70 in the horizontal direction.Therefore, even if cloth holder 50 and guiding elements 69 are connected and this cloth holder 50 is fixed on Y-axis mobile member 73, the motion track of the cloth kept by retaining member 90 can also be adjusted.Therefore, cloth-feeding device 10 can suppress the assembly error between the scale error of the component because forming cloth holder 50, component etc. and cause the motion track of cloth to produce deviation for each cloth-feeding device 10.
Plane in horizontal direction parallel of upper surface 72A.When four screw members 46 are unscrewed by operator, retaining member 90 easily slides relative to upper surface 72A.Therefore, cloth-feeding device 10 easily can adjust the fixed position of retaining member 90 relative to fixed component 70.Retaining member 90 is arranged on the upper surface 72A of the support 72 of fixed component 70.Compared with when retaining member 90 being arranged on fixed component 70 front, cloth-feeding device 10 can make retaining member 90 length in the longitudinal direction longer under the prerequisite that can not maximize.Therefore, cloth-feeding device 10 can suppress to maximize, and can guarantee retaining member 90 length in the longitudinal direction.
As long as operator is by after unscrewing four screw members 46 and move retaining member 90 in the horizontal direction, then by fastening for four screw members 46, just can adjust the fixed position of retaining member 90 relative to fixed component 70.Therefore, Sewing machines 1 easily can adjust the fixed position of retaining member 90 relative to fixed component 70.Retaining member 90 by setting unit 92,94 being fixed on the upper surface 72A of support 72, can be fixed on fixed component 70 by operator.Setting unit 92,94 is that therefore, arm 81 can be stably fixed on fixed component 70 by operator in the left and right sides portion of arm 81 and the tabular of horizontal direction parallel.Therefore, cloth-feeding device 10 can stably move arm 81, thus can stably carry the cloth being maintained at arm 81 front.

Guiding elements 69 is located at a pair clamping part 62 position from the guide rail portion, both sides 76 above-below direction.Because guiding elements 69 is not interposed between extended portion 74 and orbit portion 76, therefore fixed component 70 length in the longitudinal direction shortens.Therefore, it is possible to make cloth-feeding device 10 miniaturized.
The upper surface 72A of the support 72 of the arm 81 self-retaining component 70 of retaining member 90 extends to the side i.e. front side contrary with orbit portion 76 that side residing.Compared with during position beyond upper surface 72A arm 81 being located at support 72, fixed component 70 length in the longitudinal direction shortens.Therefore, it is possible under the prerequisite not increasing cloth-feeding device 10 length in the longitudinal direction, guarantee arm 81 length in the longitudinal direction.Cloth-feeding device 10 can guarantee that operator configures will space required for the cloth kept by press box 84 and gripper frame 87 being located at arm 81 tip side.Therefore, cloth-feeding device 10 can improve operability when processing cloth.
The front surface 76A of orbit portion 76 extends with left and right directions along the vertical direction, and orthogonal with fore-and-aft direction.Compared with the left and right directions both ends of extended portion 74, the left and right directions central portion of extended portion 74 caves in the mode forwards leaving front surface 76A.Extended portion 74 arranges retaining member 90 at the upper surface 72A of support 72.Therefore, because of intermittently driving shaft 68 to fixed component 70 acting inertial power time, the central portion of extended portion 74 is easy to left and right directions both ends as fulcrum bends.The amount of bow of extended portion 74 and the side-play amount of cloth are not easily consistent by extended portion 74 position influence in the lateral direction.Therefore, cloth-feeding device 10 can make the side-play amount stabilisation more of the cloth when temporarily being stopped by the cloth of intermittently movement mobile.Therefore, Sewing machines 1 can reduce the possibility of the needle tracking that cannot form expectation further.
