Description

Stacking device for sewing machines

technical field

The present invention relates to a stacker device of a sewing machine for placing a sewn object at a certain position.

Background technique

Conventionally, there is known a stacking device for a sewing machine that stacks a sewn object (sewn product) at a predetermined position.

For example, the stacker S of the sewing machine shown in FIG. 7 is installed on the side of the sewing machine table T on the downstream side of the sewing machine head M in the cloth feeding direction. Furthermore, the stacking rod L is driven by a driving force such as a drive cylinder, and by performing a predetermined stacking operation, that is, a loading operation, the sewn object after sewing is stacked on the loading rod RB provided between the stacking rods L. .

In addition, in order to prevent the operator from contacting the working part performing the stacking operation, a frame-shaped safety bar SB extending in the horizontal direction surrounding the entire working range of the stacking lever is provided (for example, refer to Patent Document 1).

Moreover, when a large number of sewn objects are piled up on the loading bar RB, the operator stands at the side position (the upper and lower positions in FIG. 7 ) or the front position (the left position in FIG. 7 ) of the safety bar SL, and places the loading bar RB on the The sewn object is pulled up to the left in Fig. 7, thereby removing the sewn object from the loading bar RB.

However, in the aforementioned conventional sewing machine stacking device, the safety bar SB is fixedly installed in a state extending horizontally from the side of the sewing machine table T. As shown in FIG. Therefore, for example, when taking out the to-be-sewn object on the loading bar RB, since the safety bar SB cannot be moved from the above-mentioned fixed position, the safety bar SB becomes an obstacle to the taking-out operation.

That is, in order to prevent the lifted sewn object from hitting the safety bar SB, the operator needs to lift it up sufficiently and then take it out to the left, which places a heavy burden on the operator's arms and waist. In addition, when working in front of the safety bar SB, it must also be located outside the safety bar SB away from the loading bar SB, and the take-out work must be performed from a distance, so that the operator takes a forced posture, and the waist of the operator is strained. And the problem that an arm puts a big burden on.

(clamping lever, etc.)

Next, the respective rods 21, 22, 23, and 24 performing the stacking operation will be described.

First, the loading rod 21, the clothing swinging rod 22, the first clamping rod 23, and the second clamping rod 24 are all formed in an approximately L-shape, and one end side thereof is supported as a vertical rod, and the other end is supported as a vertical rod. The sides are all parallel to the X-axis direction, and are provided as a horizontal bar related to the material during the accumulation operation. The horizontal bar is formed to perform accumulation operations such as guiding operation, swinging operation, placing operation, or clamping (pressing) operation of the material. structure (see Figure 3).

In addition, each bar 21, 22, 23, 24 is arrange|positioned so that each horizontal bar may be parallel to each other, and also parallel to the end edge of the sewing machine table 2, respectively.

In addition, each rod 21, 22, 23, 24 is set so that it becomes almost the same height as the sewing machine table 2 in the working position, so that the sewing machine table 2 hanging from the end edge of the sewing machine table 2 can be efficiently loaded (stacked). Fabric (refer to Figure 1 and Figure 2).

In addition, each vertical rod of each rod 21, 22, 23, 24 is from the upstream side of the cloth feeding direction, that is, the front, according to the loading rod 21, the second clamping rod 24, the cloth swinging rod 22, the first clamping rod 23 The sequential arrangement of the stacks is an arrangement for avoiding mutual interference during the stacking operation (described later) (see FIG. 5 ).

In the loading rod 21, its vertical rod is rotatably connected to one end on the front side of the above-mentioned support shaft 11 (inner shaft 11a), and its horizontal rod is arranged at a position away from the sewing machine table 2, and the length of the horizontal rod is The direction is along the cloth feeding direction (X-axis direction).

One end of a fourth air cylinder 34 is rotatably connected to the vertical rod of the mounting rod 21 . In addition, the other end of the fourth air cylinder 34 is rotatably coupled to an extension member 10d extending in the Y-axis direction from the frame 10 described above. And, by the expansion and contraction of the fourth air cylinder 34, the vertical bar of the loading rod 21 swings around the support shaft 11, and the horizontal bar of the loading rod 21 reciprocates between the loading position where the cloth is placed and the specific loading position. between the lower positions further below.

In addition, the lower position refers to the position for taking out the cloth placed on the placing rod 21. The details will be described later, but the cloth placed on the placing rod 21 is placed above the placing rod 21 to prevent it from falling. The first clamp rod 23 is held, and the holding of the cloth by the first clamp rod 23 and the mount rod 21 can be released by moving the placing rod 21 to the lower position, so that the operator can easily take out the cloth.

One end of the longitudinal rod of the clothing swing lever 22 is rotatably connected to the other end of the support member 12 via the support shaft 14 . One end of the second air cylinder 32 is rotatably connected to the vertical rod of the cloth swinging rod 22 . The other end of the second cylinder 32 is rotatably coupled to the lower portion of the frame 10 . And, by expansion and contraction of the second air cylinder 32 , the clothing swing lever 22 swings around the support shaft 14 , and reciprocates largely over the top of the mounting rod 21 .

The vertical rod of the first clamp rod 23 is rotatably connected to the upper part of the support frame 10 b of the frame 10 via the support shaft 13 . One end of a third air cylinder 33 is rotatably connected to the vertical rod of the first clamp rod 23 . The other end of the third air cylinder 33 is rotatably coupled to a support frame 10c extending rightward in the Y-axis direction from a support frame 10b of the frame 10 . Moreover, the first clamping rod 23 is extended and contracted by the third air cylinder 33, and its horizontal rod reciprocates between the holding position abutting against the upper part of the loading rod 21 and the retracted position above it, as the holding position of the present embodiment. components are set.

As mentioned above, the second clamping rod 24 has its vertical rod fixed to the approximate center of the support member 12 and its horizontal rod disposed near the end edge of the sewing machine table 2 (see FIGS. 3 and 4 ). In addition, one end of the first air cylinder 31 is rotatably connected to the vicinity of the other end of the support member 12 . The other end of the first air cylinder 31 is rotatably connected to the lower portion of the frame 10 . Then, when the first air cylinder 31 expands and contracts, the support member 12 swings around the support shaft 11, and the clothing swing lever 22 and the second clamp lever 24 connected to the support member 12 also swing together. The rocking of the support member 12 driven by the first air cylinder 31 causes the material swing lever 22 and the second clamp lever 24 to reciprocate between the vicinity of the end edge of the sewing machine table 2 and the mounting lever 21 together. The second clamp rod 24 is integrally swung with the support member 12 by the extension and contraction of the above-mentioned first air cylinder 31 , and its horizontal rod is at a retracted position near the end edge of the sewing machine table 22 and a holding position where it abuts against the loading rod 21 . Move back and forth between.

When the first clamp rod 23 and the second clamp rod 24 are arranged at the holding position, their cross bars are pressed by a predetermined pressure by the cross bar of the mounting rod 21 . In addition, in the stacking operation described later, any one of the clamp levers is always arranged at the holding position. That is, the first and second clamp levers 23 and 24 alternately clamp and prevent the sewn fabric placed on the placing lever 21 from falling by cooperating with the placing lever 21 .

(safety bar)

Next, the safety bar 25 of this embodiment will be described.

As shown in FIG. 5 , the safety bar 25 is a substantially U-shaped frame member in plan view.

The safety bar 25 is used to prevent the operator or the like from touching the bars 21 , 22 , 23 , 24 in order to ensure smooth stacking operation of the bars 21 , 22 , 23 , 24 when the sewing machine 1 is in operation. Therefore, during the stacking operation of the safety bar 25, the substantially U-shaped frame portion is maintained at a height close to the above-mentioned sewing machine table 2, and is formed to sufficiently surround the bars 21, 22, 23, and 24 for the loading operation. The size of the entire area of the movable range (see Figure 1).

Here, the safety lever 25 of this embodiment is rotatably connected to the support shaft 11 (inner shaft 11 a ) at one end, that is, the rear end, and the other end, that is, the front end, is connected to the mounting rod 21 described above. The front end is connected (refer to Figure 4).

That is, the safety bar 25 is connected to the mounting rod 21, is integrated with the mounting rod 21, and is rotatably connected to the frame 10 via the support shaft 11 (inner shaft 11a). Therefore, the safety lever 25 can swing around the support shaft 11 which is the same swing center as the swing center of the loading rod 21 . During the execution of the stacking operation, the safety bar 25 maintains a substantially U-shaped frame portion extending in the horizontal direction. In addition, since the safety rod 25 is connected to the mounting rod 21 , it is driven by the fourth air cylinder 34 connected to the vertical rod of the mounting rod 21 . That is, the safety bar 25 of this embodiment is driven to descend and ascend by the fourth air cylinder 34 , which is the same drive source, in conjunction with the loading rod 21 (see FIG. 6 ).

The fourth air cylinder 34 is driven by the operation of an unillustrated operation pedal, and is switched on/off when a depression detection signal of the operation pedal is detected.

In addition, the respective rods 21 , 22 , 23 , and 24 are controlled by a control unit not shown to perform predetermined stacking operations.

Furthermore, the stacking device 100 drives the respective rods 21, 22, 23, and 24 at predetermined timings in conjunction with the sewing operation, particularly the cloth feeding operation, so as to stack and place the cloth after sewing on the loading rod 21. The loading operation is the stacking operation (described later).

(Description of loading operation)

Here, the stacking operation of the stacker 100 , that is, the loading operation will be described.

In the stacking device 100, first, during the sewing of the clothing material, the clothing material swinging lever 22 and the second clamping lever 24 are arranged in the vicinity of the end edge on the downstream side of the sewing machine table 2 in the cloth feeding direction, and are arranged in parallel with the end edge. The loading rod 21 and the first clamp rod 23 are arranged side by side at positions where these clothing swing rods 22 and the second clamp rod 24 are parallel and separated (see FIG. 1 and FIG. 3 ). In this state, the fourth air cylinder 34 protrudes, and the loading rod 21 is arranged at the loading position. On the other hand, the third air cylinder 33 contracts, and the first clamp rod 23 comes into contact with the peripheral surface of the mounting rod 21 from above. In addition, when the cloth which has already been sewn is loaded, the cloth is clamped and held by the cooperation of these loading rods 21 and the first clamp rod 23, and it is prevented from falling.

Then, when the cloth is fed from the upstream side to the downstream side in the cloth feeding direction, the cloth guided by the above-mentioned sub-table 2 b is arranged above the cloth swinging lever 22 and the second clamping lever 24 . Then, when it is detected by a cloth sensor not shown that the cloth has been sent to a predetermined position, the first air cylinder 31 contracts. That is, in the state where the first clamping lever 23 clamps (holds) the cloth on the loading rod 21 , the clothing swinging lever 22 connected to the supporting member 12 and the second clamping rod 24 move toward the loading rod 21 together. . Therefore, the cloth which is located downstream in the cloth feeding direction after sewing and hangs down from the edge of the sewing machine table 2 is guided by the cloth swinging rod 22 and the second clamping rod 24 to approach the loading rod 21 side. At this time, the second clamping rod 24 presses against the loading rod 21 through the cloth, and cooperates with the loading rod 21 to clamp (hold) the cloth.

Then, the third air cylinder 33 protrudes, and the first clamp lever 23 rises. Afterwards, through the expansion and contraction of the second air cylinder 32, the clothing material swinging lever 22 executes from the vicinity of the end edge of the sewing machine table 2 through the top of the loading bar 21, that is, the horizontal bar of the loading bar 21 and the horizontal bar of the first clamping bar 23. Between the rods, after making the cloth jump, return to the cloth waving action near the end edge of the sewing machine table 2. Then, when the swinging motion of the clothing material is completed, the third air cylinder 33 is contracted, and the first clamp rod 23 abuts against the placing rod 21 from above again. Then, after the cloth is held, the first air cylinder 31 is protruded again, so that the cloth swinging lever 22 and the second clamping lever 24 move to the vicinity of the end edge of the sewing machine table 2 on the downstream side in the cloth feeding direction.

That is, the stacking device 100 of the present embodiment is clamped by the loading rod 21, the first clamping rod 23, or the second clamping rod 24, and the cloth placed on the loading rod 21 is always held by any clamping rod. , to prevent it from falling.

Then, by repeatedly performing this stacking operation (cloth swinging operation), the sewn cloth is moved from the sewing machine table 2 to the loading rod 21, and stacked and placed automatically.

In addition, in the sewing machine stacking device 100 of this embodiment, in order to take out the cloth, the operator steps down the operation pedal, and when the stepping down is detected, the fourth air cylinder 34 is contracted, and the safety bar 25 is lowered together with the loading rod 21. (Refer to Figure 6).

That is, when the pedal is operated by the operator to output a depression signal to a control unit not shown, the control unit that detects the depression signal outputs a signal to the solenoid valve to drive (contract) the fourth air cylinder 34 .

The fourth air cylinder is in a protruding state to push the loading rod 21 to the operating position during the stacking operation, and thus is released from the pushing state by the operation of the operation pedal to be retracted. And, by the contraction of the fourth air cylinder 34, the loading rod 21 descends and moves to the lower position, thereby the first clamping rod 23 and the loading rod 21 holding the cloth can be separated, and the holding of the cloth is released, thereby Cloth can be removed by the operator.

In the present embodiment, the mounting rod 21 and the safety rod 25 are connected and provided so as to be integrally movable, so when the fourth air cylinder 34 contracts, the safety rod 25 is also centered on the supporting shaft 11 together with the mounting rod 21 Rotate and descend (Fig. 2, double dot dash line), the front side moves downward.

As described above, according to the sewing machine 1 of the present embodiment, the safety bar 25 as a protective member can move below the position surrounding the space in which the mounting bar 21 and the material swinging bar 22 reciprocate. Accordingly, an operator can easily approach the loading rod 21 from the outside of the safety rod 25 . In addition, even if the operator stands sideways (up and down in FIG. 5 ) or in front of the safety bar 25 (upper and lower in FIG. 5 ) when taking out the sewn fabric placed on the loading rod 21 Therefore, the safety bar 25 does not become an obstacle to the operation, and compared with the stacking device of the existing sewing machine in which the safety bar 25 is fixed, it is extremely easy to take out the cloth.

In addition, the longitudinal rod of the safety bar 25 is connected to the loading rod 21, and moves around the support shaft 11 so that the front end thereof moves downward in conjunction with the movement of the loading rod 21 to the downward position. When the rod 21 moves downward, the front end portion of the safety rod 25 also moves downward. Therefore, for example, it is not necessary to separately perform an operation for lowering the loading rod 21 and an operation for lowering the safety bar 25 when taking out the sewn cloth placed on the loading rod 21 . Thereby, the taking-out operation can be performed more easily, and the convenience of the stacking device 100 of the sewing machine 1 can be significantly improved.

In addition, both the loading rod 21 and the safety rod 25 swing around the same swing center, that is, around the support shaft 11 . Thus, for example, it is not necessary to use a new member for moving the safety bar 25 downward. Therefore, a structure for moving the safety bar 25 downward can be easily realized, and in addition to that, the cost can be reduced, and the above-mentioned effects can be easily obtained.

(other)

Furthermore, in this embodiment, the safety bar 25 adopts a structure in which the front end side is lowered centered on the base end side, but it is not necessarily limited thereto. For example, the base end side can freely slide up and down relative to the frame 10. A structure in which the safety bar 25 descends while maintaining the entire level may be employed.

In addition, in this embodiment, the safety bar 25 is supported by the supporting shaft 11, which is the same support member as the loading rod 21, and is driven by the fourth air cylinder 34, which is the same driving source as the loading rod 21, but it may also be used with the loading rod 21. The loading rods 21 are individually provided with different drive sources, and are individually lowered by input from other operating members such as pedals.

In addition, of course, the safety bar 25 may be configured to move up and down manually without being connected to a driving source.

In addition, the stacking device 100 of the present embodiment has a first clamp rod 23 for holding the cloth, and when taking out the cloth, in order to release the holding of the first clamp rod 23, the placing rod 21 is lowered. However, in a stacking device that does not have a clamp bar for holding the cloth, it is not necessary to lower the placing rod 21 when taking out the cloth. However, if the safety bar 25 can be moved downward also in this case, the operator can easily take out the cloth. Furthermore, in the stacking device as described in the prior art, it is sufficient that the safety bar can be moved independently.
