Japanese Patent Publication No. 60-32473

  However, in the conventional sewing machine stacker, the safety bar is fixedly provided in a state of extending horizontally from the side of the sewing machine table. For this reason, for example, when taking out the sewing product after completion of sewing placed on the placement bar, the safety bar could not be moved from the fixed position, so that the safety bar hinders the take-out operation. There is a problem that the burden on the operator may be heavy because the take-out operation must be performed from a distance.

  The present invention has been made in view of the above problems, and an object thereof is to improve the convenience of a sewing machine stacker apparatus.

  In order to solve the above-mentioned problem, the invention according to claim 1 is configured to reciprocate between a placement member for placing a sewing product after sewing by a sewing machine, a vicinity of the sewing machine table, and a vicinity of the placement member. A guide member that guides the workpiece to the mounting member, and a base end portion supported by the sewing machine table so as to surround the space in which the mounting member and the guide member reciprocate. In the sewing machine stacker device including the protective member extending in the direction, the protective member is provided so as to be movable downward from a position surrounding the reciprocating space of the placement member and the guide member. This is a sewing machine stacker device.

  According to a second aspect of the present invention, in the sewing machine stacker device according to the first aspect of the present invention, the sewing machine stacker device further includes a holding member that holds a workpiece to be sewn placed on the mounting member with the mounting member. The member includes a placement position where the sewing product guided by the guide member is placed, and a lower position below the placement position where the holding member can be released from being held by the holding member. The protective member is connected to the mounting member, and at least a tip of the protective member moves downward in conjunction with the movement of the mounting member to the lower position. .

  According to the first aspect of the present invention, the protection member can move downward from a position surrounding the space in which the mounting member and the guide member reciprocate. This facilitates access to the placement member or the guide member from the outside of the protection member. Therefore, for example, when taking out the sewing product after completion of sewing placed on the placement member, the protection member does not hinder the work, and the conventional sewing machine stacker device in which the protection member is fixed is used. However, the sewing product after sewing can be taken out very easily.

  According to the second aspect of the present invention, the same effect as that of the first aspect of the invention can be obtained, and the sewing machine stacker device further includes a holding member for holding the sewing product with the protective member. Since it has, the to-be-sewn material after completion | finish of sewing mounted in the mounting member can be reliably hold | maintained between protection members. The placement member includes a placement position when the guide member guides the article to be sewn and places the article on the placement member, and holds the article to be sewn by the holding member below the placement position. Can be moved to a releasable lower position. Furthermore, the protection member is connected to the mounting member, and at least the tip thereof is moved downward in conjunction with the movement of the mounting member to the lower position. Thereby, when the mounting member moves to the lower position, the protection member also moves downward. That is, the placing member is moved to the lower position, and the sewing object held by the placing member and the holding member is released, and the sewing object after sewing can be taken out. When the protective member is moved downward along with the downward movement, it is very suitable when the sewing product placed on the placement member is taken out. Therefore, for example, when taking out the sewing product after completion of sewing placed on the placement member, it is necessary to separately perform an operation for lowering the placement member and an operation for lowering the protection member. Absent. As a result, the post-sewing workpiece to be sewn placed on the placing member can be more easily taken out, and the convenience of the stacker device of the sewing machine can be improved.

The horizontal bar is a fabric guiding operation, a paying operation, a placing operation or a clamping (pressing) ) And other stack operations (see FIG. 3).
The bars 21, 22, 23, and 24 are arranged such that the horizontal bars are parallel to each other and the edge of the sewing machine table 2 is also parallel to each other.
In addition, each bar 21, 22, 23, 24 has the sewing machine table 2 in the operating position so that the fabric suspended from the edge of the sewing machine table 2 can be efficiently placed (stacked) after the sewing is finished. It is provided so that it may become substantially the same height (refer FIG.1 and FIG.2).
Further, the bars 21, 22, 23, 24 are arranged in the order of the placing bar 21, the second clamp bar 24, the dough wiping bar 22, and the first clamp bar 23 from the upstream in the cloth feeding direction, that is, from the front. Thus, when performing a stack operation (described later), the arrangement avoids mutual interference (see FIG. 5).

The mounting bar 21 has a vertical bar rotatably connected to one end on the front side of the support shaft 11 (inner shaft 11a), and the horizontal bar is located at a position where the horizontal bar is separated from the sewing machine table 2. It arrange | positions so that the longitudinal direction of a stick | rod follows a cloth feed direction (X-axis direction).

The other end of the fourth air cylinder 34 is rotatably connected to an extending member 10d extending from the frame 10 in the Y-axis direction. When the fourth air cylinder 34 expands and contracts, the vertical bar of the placement bar 21 is swung around the support shaft 11, and the horizontal bar of the placement bar 21 is placed on which the fabric is placed. It is configured to reciprocate between a position and a lower position below the placement position.
The lower position is a position for taking out the fabric placed on the placement bar 21 and will be described in detail later. However, the fabric placed on the placement bar 21 is placed to prevent the fabric from falling. It is held by the first clamp bar 23 from above the placement bar 21, and the holding of the fabric by the first clamp bar 23 and the placement bar 21 can be released by moving the placement bar 21 to a lower position. The operator can easily take out the fabric.

  The dough wiping bar 22 has one end of a vertical bar thereof rotatably connected to the other end of the support member 12 described above via a support shaft 14. One end of the second air cylinder 32 is rotatably connected to the vertical bar of the dough removing bar 22. The other end of the second air cylinder 32 is rotatably connected to the lower part of the frame 10. When the second air cylinder 32 expands and contracts, the dough wiping bar 22 is swung around the support shaft 14 and reciprocally moves far above the placement bar 21.

  The first clamp bar 23 is pivotally connected to the upper portion 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 bar of the first clamp bar 23. The other end of the third air cylinder 33 is rotatably connected to a support frame 10c that extends from the support frame 10b of the frame 10 to the right along the Y-axis direction. The first clamp bar 23 reciprocates between a holding position where the horizontal bar abuts on the upper portion of the mounting bar 21 and a retracted position above the horizontal bar 33 when the third air cylinder 33 expands and contracts. And is provided as a holding member in the present embodiment.

  As described above, the vertical bar of the second clamp bar 24 is fixed to the substantially central portion of the support member 12, and the horizontal bar is disposed in the vicinity of the edge of the sewing machine table 2 (FIG. 3, FIG. 3). 4). Further, 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 part of the frame 10. When the first air cylinder 31 expands and contracts, the support member 12 is swung around the support shaft 11, and the dough removal bar 22 and the second clamp bar 24 connected to the support member 12 are swung together. By the swinging of the support member 12 based on the driving of the first air cylinder 31, the dough wiping bar 22 and the second clamp bar 24 both reciprocate between the vicinity of the edge of the sewing machine table 2 and the mounting bar 21. It is configured to do. The second clamp bar 24 is swung integrally with the support member 12 by the expansion and contraction of the first air cylinder 31 described above, and the horizontal bar contacts the retracted position near the edge of the sewing machine table 2 and the mounting bar 21. It is configured to reciprocate between the holding positions in contact.

  When the first clamp bar 23 and the second clamp bar 24 are arranged at the holding position, the horizontal bar is pressed against the horizontal bar of the mounting bar 21 with a predetermined pressure. One of the clamp bars is always arranged at the holding position during the stacking operation described later. That is, the first and second clamp bars 23 and 24 cooperate with the placement bar 21 to alternately hold the cloth after the sewing placed on the placement bar 21 and prevent the cloth from falling.

(Safety bar)
Next, the safety bar 25 in this embodiment will be described.
As shown in FIG. 5, the safety bar 25 is a frame-like member that has a substantially U-shape in plan view.
The safety bar 25 is in contact with the bars 21, 22, 23, and 24 in order to ensure the smooth stacking operation of the bars 21, 22, 23, and 24 when the sewing machine 1 is in operation. It is for preventing. For this reason, the safety bar 25 is configured so that the substantially U-shaped frame portion is held at a height close to the above-described sewing machine table 2 during the stacking operation, and the bars 21, 22, and 23 that perform the mounting operation. , 24 is sufficiently large to enclose the entire movable range (see FIG. 1).

Here, the safety bar 25 in the present embodiment is rotatably connected to the support shaft 11 (inner shaft 11a) at one end, that is, the rear end, and the other end, that is, the front end. It connects with the front-end part of the mounting bar 21 mentioned above (refer FIG. 4).
That is, the safety bar 25 is connected to the mounting bar 21 so as to be integrated with the mounting bar 21 and is rotatably connected to the frame 10 via the support shaft 11 (inner shaft 11a). . For this reason, the safety bar 25 can swing about the same swing center as the swing center of the mounting bar 21, that is, the support shaft 11. The safety bar 25 is held in a state where the substantially U-shaped frame portion extends in the horizontal direction during execution of the stacking operation. Further, since the safety bar 25 is connected to the mounting bar 21, the safety bar 25 is driven by a fourth cylinder 34 connected to the vertical bar of the mounting bar 21. That is, the safety bar 25 in the present embodiment is configured to be moved down and up by the fourth air cylinder 34 that is the same drive source in conjunction with the mounting bar 21 (see FIG. 6).
The fourth air cylinder 34 is driven in response to an operation of an operation pedal (not shown), and is switched ON / OFF when a depression detection signal of the operation pedal is detected.
Each of the bars 21, 22, 23, and 24 is controlled to perform a predetermined stack operation by a control unit (not shown).

  Then, the stacker device 100 drives each bar 21, 22, 23, 24 at a predetermined timing by interlocking with the sewing machine operation, in particular, the cloth feeding, and superimposes the cloth after the sewing on the placement bar 21. A placement operation to be placed, that is, a stack operation (described later) is performed.

(Explanation of mounting operation)
Here, a stacking operation, that is, a mounting operation of the stacker apparatus 100 will be described.
In the stacker device 100, first, during sewing of the fabric, the fabric wiper bar 22 and the second clamp bar 24 are arranged in parallel with the edge in the vicinity of the downstream edge of the sewing machine table 2 in the fabric feeding direction. A placement bar 21 and a first clamp bar 23 are arranged side by side at positions parallel to and spaced from the paying bar 22 and the second clamp bar 24 (see FIGS. 1 and 3). In this state, the fourth air cylinder 34 protrudes, and the mounting bar 21 is disposed at the mounting position. On the other hand, the third air cylinder 33 is contracted so that the first clamp bar 23 comes into contact with the peripheral surface of the mounting bar 21 from above. Further, when the cloth after the sewing is already placed, the cloth is clamped and held by the cooperation of the placement bar 21 and the first clamp bar 23 so as not to fall.

  Next, when the fabric is fed from the upstream side to the downstream side in the fabric feeding direction, the fabric guided by the sub-table 2b described above is disposed above the fabric wiper bar 22 and the second clamp bar 24. When the cloth sensor (not shown) detects that the cloth has been sent to a predetermined position, the first air cylinder 31 is contracted. That is, with the first clamp bar 23 sandwiching (holding) the fabric on the placement bar 21, both the fabric wiper bar 22 and the second clamp bar 24 connected to the support member 12 are placed on the placement bar 21 side. Moved. For this reason, the cloth that is located downstream in the cloth feeding direction after sewing and is suspended downward from the edge of the sewing machine table 2 is guided by the cloth wiping bar 22 and the second clamp bar 24 to the placement bar 21 side. It is sent. At this time, the second clamp bar 24 is pressed against the placement bar 21 through the cloth, and clamps (holds) the cloth in cooperation with the placement bar 21.

Next, the third air cylinder 33 protrudes and the first clamp bar 23 is raised. Thereafter, the second air cylinder 32 expands and contracts, so that the dough wiping bar 22 moves from the vicinity of the edge of the sewing machine table 2 above the placement bar 21, that is, across the horizontal bar of the placement bar 21 and the first clamp bar 23. After passing between the bars and jumping up the fabric, a cloth wiping operation is performed to return to the vicinity of the edge of the sewing machine table 2 again. Then, when the dough removal operation is finished, the third air cylinder 33 is contracted and the first clamp bar 23 is again brought into contact with the placement bar 21 from above. Then, after the fabric is held, the first air cylinder 31 is protruded again, so that the cloth wiper bar 22 and the second clamp bar 24 are moved to the vicinity of the edge of the sewing machine table 2 on the downstream side in the cloth feeding direction.
In other words, the stacker device 100 according to the present embodiment is sandwiched between the placement bar 21 and the first clamp bar 23 or the second clamp bar 24 so that any one of the clamp bars is always placed on the placement bar 21. Hold the applied fabric to prevent it from falling.
Then, by repeatedly executing such a stacking operation (fabric wiping operation), the fabric after the sewing is moved from the sewing machine table 2 onto the mounting bar 21 and automatically stacked.

In the sewing machine stacker device 100 according to the present embodiment, the operator depresses the operation pedal to take out the fabric, and when this depressing is detected, the fourth air cylinder 34 is contracted, together with the placement bar 21. The safety bar 25 is lowered (see FIG. 6).
That is, when the operation pedal is operated by the operator and a depression signal is output to a control unit (not shown), a signal is output from the control unit that detects the depression signal to the electromagnetic valve, and the fourth air cylinder 34 is driven (contracted). Is done.
Since the fourth air cylinder is in a state of protruding so as to urge the mounting bar 21 to the operating position during execution of the stacking operation, the urging state is released by the operation of the operation pedal and contracted. It is what is done. The placement bar 21 is lowered by the contraction of the fourth air cylinder 34 and moved to the lower position, whereby the first clamp bar 34 and the placement bar 21 that have held the fabric are isolated, and the fabric is removed. The holding can be released, and the operator can take out the fabric.
In this embodiment, the mounting bar 21 and the safety bar 25 are connected and provided so as to be capable of integral operation. Therefore, when the fourth air cylinder 34 contracts, the safety bar 25 is also lowered together with the mounting bar 21. At that time, the tip end side (the right side in FIGS. 1 to 6) is moved downward around the support shaft 11.

As described above, according to the sewing machine 1 according to the present embodiment, the safety bar 25 serving as a protective member moves downward from a position surrounding the space in which the placement bar 21 and the dough wiping bar 22 reciprocate. Is possible. Thereby, access to the mounting bar 21 from the outside of the safety bar 25 is facilitated. Therefore, for example, when taking out the cloth after completion of sewing placed on the placement bar 21, the safety bar 25 does not hinder the work, and the conventional sewing machine stacker in which the safety bar 25 is fixed is used. The fabric can be taken out more easily than the apparatus.
The vertical bar of the safety bar 25 is connected to the mounting bar 21, and the support shaft 11 is moved so that the tip of the safety bar 25 moves downward in conjunction with the movement of the mounting bar 21 to the lower position. Since it moves to the center, when the mounting bar 21 moves to the lower position, the tip of the safety bar 25 is also moved downward. Therefore, for example, when taking out the cloth after completion of sewing placed on the placement bar 21, it is necessary to separately perform an operation for lowering the placement bar 21 and an operation for lowering the safety bar 25. There is no. Accordingly, the take-out operation can be performed more easily, and the convenience of the stacker device 100 of the sewing machine 1 can be greatly improved.
Further, both the placing bar 21 and the safety bar 25 are swung around the same swinging center, that is, the support shaft 11. Thereby, for example, it is not necessary to use a new member to move the safety bar 25 downward. Therefore, a configuration for moving the safety bar 25 downward can be easily realized, and the above-described effects can be easily obtained while reducing costs.

(Other)
In the present embodiment, the safety bar 25 is configured such that the distal end side descends around the proximal end side, but is not necessarily limited thereto. For example, the proximal end side slides up and down with respect to the frame 10. It is good also as a structure which can be moved freely and descend | falls while the said safety bar 25 whole is maintained horizontal.
In addition, in this embodiment, the safety bar 25 is supported by the same support member as the placement bar 21, that is, the support shaft 11, and is driven by the fourth air cylinder 34 that is the same drive source as the placement bar 21. However, a drive source different from the placement bar 21 may be provided so that it can be lowered independently by input of a pedal or other operation means.
Needless to say, the safety bar 25 may be configured to be manually movable up and down without being connected to a drive source.
Further, the stacker device 100 of the present embodiment has a first clamp bar 23 for holding the fabric. When the fabric is taken out, the loading bar is used to release the holding by the first clamp bar 23. In the stacker device that does not include the clamp bar for holding the fabric, it is not necessary to lower the placement bar 21 when taking out the fabric. However, also in this case, if the safety bar 25 can be moved downward, the operator can easily take out the fabric.
