  The operation panel 10 receives an input operation by the operator 2 standing in front of the operation panel 10. The operation panel 10 is composed of, for example, a touch panel. The operator 2 can operate, stop, and set the injection molding machine by operating the operation panel 10.

  The operation panel 10 can turn between a home position (the position shown in FIG. 2) for operating the operation panel 10 and a retracted position (a position shown in FIG. 4) retracted from the home position. The operation panel 10 is normally fixed at the home position, and is retracted to the retracted position during maintenance of the injection device disposed behind the operation panel 10. The retreat position may be set in front of the home position.

  For example, the operation panel 10 can turn around a vertical axis. The operation panel 10 may be turnable about a horizontal axis, and the direction of the turning center line of the operation panel 10 is not particularly limited.

  The operation panel 10 is basically operated at the home position, but it is naturally possible to operate the operation panel 10 at a position other than the home position.

  The support member 20 supports the operation panel 10. The operation panel 10 is disposed on the right side of the support member 20 when in the home position as shown in FIG.

  The connection tool 30 connects the operation panel 10 to the support member 20 so as to be rotatable between a home position and a retracted position. The connector 30 is configured by a hinge or the like. For example, a torque hinge or the like is used as the connection tool 30 so that the operation panel 10 can be stopped at an arbitrary position between the home position and the retracted position.

  The turning member 40 turns together with the operation panel 10. The turning member 40 may be attached to the rear surface 11 of the operation panel 10 so as not to be seen by the operator 2 standing in front of the operation panel 10.

  When viewed from a direction parallel to the turning center line of the operation panel 10 (for example, when viewed from above), the turning member 40 is perpendicular to the rear surface 11 of the operation panel 10 as shown in FIGS. A vertical portion 41 and a parallel portion 42 parallel to the rear surface 11 of the operation panel 10 are provided.

  When the operation panel 10 is in the retracted position as shown in FIG. 4, the parallel portion 42 comes into contact with the right wall 51 of the fixing member 50, thereby reversing the direction from the retracted position toward the home position (FIG. 4). In the clockwise direction) is limited.

  For example, as shown in FIG. 1, the pivot member 40 is used in a pair of upper and lower sides. The pair of upper and lower turning members 40 are connected by a connecting member 45. The pair of upper and lower turning members 40 and the connecting member 45 may be integrally formed. The pair of upper and lower turning members 40 may be formed separately, and the connecting member 45 may not be provided.

  The fixing member 50 is fixed to the support member 20. The fixing member 50 may be attached to the support member 20, but as shown in FIG. 2, it is attached to an attachment member 80 different from the support member 20, and fixed to the support member 20 via the attachment member 80 or the like. May be.

  The fixing member 50 may be disposed behind the support member 20 so as not to be seen by the operator 2 standing in front of the operation panel 10.

  The fixing member 50 has a right wall portion 51 that faces the vertical portion 41 of the turning member 40 when the operation panel 10 is at the home position. A screw hole 51a is formed in the right wall 51, and a fastening bolt 60 is screwed into the screw hole 51a.

  The fixing member 50 further includes a left wall portion 52 that is parallel to the right wall portion 51, and a rear wall portion 53 that connects the rear end of the right wall portion 51 and the rear end of the left wall portion 52. A space surrounded by the right wall portion 51, the left wall portion 52, and the rear wall portion 53 includes a part of the turning path of the parallel portion 42 of the turning member 40. A part of the turning path of the parallel portion 42 can be hidden from the left, right, and rear three directions. It is possible to limit the entry of foreign matter into the turning path from these three directions.

  For example, as shown in FIG. 1, the fixing member 50 is used in a pair of upper and lower sides.

  The lower fixing member 50 further includes a lower wall portion 55 that covers a space surrounded by the right wall portion 51, the left wall portion 52, and the rear wall portion 53 from below. The lower fixing member 50 may open a space surrounded by the right wall portion 51, the left wall portion 52, and the rear wall portion 53 upward.

  On the other hand, the upper fixing member 50 further includes an upper wall portion 56 that covers a space surrounded by the right wall portion 51, the left wall portion 52, and the rear wall portion 53 from above. The upper fixing member 50 may open downward a space surrounded by the right wall portion 51, the left wall portion 52, and the rear wall portion 53. This space includes a part of the turning path of the parallel portion 42 of the upper turning member 40.

  With the upper wall portion 56 of the upper fixing member 50 and the lower wall portion 55 of the lower fixing member 50, a part of the turning path of the parallel portion 42 can be hidden from the upper and lower two directions. It is possible to limit the entry of foreign matter into the turning path from these two directions.

  When the operation panel 10 is at the home position as shown in FIG. 2, the fastening bolt 60 fastens the turning member 40 to the fixing member 50 so as not to turn. Thereby, the operation panel 10 cannot be turned at the home position. Vibration can be suppressed during operation of the operation panel 10, and erroneous operations such as pressing twice due to vibration can be suppressed.

  For example, as shown in FIG. 1, the fastening bolts 60 are used in a pair of upper and lower sides. The lower fastening bolt 60 fastens the lower turning member 40 to the lower fixing member 50 so as not to turn. The upper fastening bolt 60 fastens the upper turning member 40 to the upper fixing member 50 so as not to turn.

  In addition, although the fastening bolt 60 of this embodiment is used by a pair of upper and lower sides, you may be used only by any one. For example, only the lower fastening bolt 60 may be used. In this case, the upper fixing member 50 and the upper turning member 40 are not intended to fix the operation panel 10 so as not to be turnable at the home position, but in a direction opposite to the direction from the retracted position toward the home position (clockwise in FIG. 4). This is used for the purpose of limiting the turning of the operation panel 10 in the direction). The number of fastening bolts 60 may be three or more.

  The fastening bolt 60 includes, for example, a screw shaft portion 61 and a head portion 62. The screw shaft portion 61 passes through the through hole 41 a of the vertical portion 41 of the turning member 40 and is screwed into the screw hole 51 a of the right wall portion 51 of the fixing member 50. The head 62 is disposed on the right side of the vertical portion 41. When the head 62 is rotated, the head 62 approaches and comes into contact with the vertical portion 41 from the right side. When the head 62 is further rotated, the head 62 pushes the vertical portion 41 toward the right wall portion 51. As will be described in detail later, the vertical portion 41 is restricted from turning in the direction toward the right wall portion 51 (the direction opposite to the direction from the home position toward the retracted position). A fastening force that is impossible to fasten is generated.

  The fastening bolt 60 of this embodiment is screwed into the screw hole 51a of the right wall 51 of the fixing member 50, but may be fixed to the right wall 51 of the fixing member 50. In this case, the direction of the fastening bolt 60 is opposite to the direction shown in FIG. The head portion 62 is fixed to the right wall portion 51, and the screw shaft portion 61 passes through the through hole 41 a of the vertical portion 41 of the turning member 40. A fastening nut is screwed onto the tip of the screw shaft portion 61, and the fastening nut is disposed on the right side of the vertical portion 41. When the fastening nut is rotated, the fastening nut approaches and comes into contact with the vertical portion 41 from the right side. When the fastening nut is further rotated, the fastening nut pushes the vertical portion 41 toward the right wall portion 51. Since the vertical portion 41 is restricted from turning in the direction toward the right wall portion 51, a fastening force for fastening the vertical portion 41 to the right wall portion 51 so as not to turn is generated.

  The position adjustment mechanism 70 adjusts the home position of the operation panel 10. The position adjustment mechanism 70 includes, for example, an adjustment nut 71 and an adjustment bolt 72.

  The adjustment nut 71 is fixed to the vertical portion 41 of the turning member 40, and the adjustment bolt 72 is screwed to the adjustment nut 71 so as to be freely rotatable. When the operation panel 10 is at the home position, as shown in FIG. 2, the adjustment bolt 72 projects from the vertical portion 41 toward the right wall portion 51 and abuts on the right wall portion 51. As a result, the vertical portion 41 is restricted from turning in the direction toward the right wall portion 51. The position of the operation panel 10 when the adjustment bolt 72 abuts on the right wall portion 51 is the home position. The home position of the operation panel 10 can be adjusted by changing the protruding amount of the adjusting bolt 72, and the protruding amount of the adjusting bolt 72 can be adjusted by rotating the adjusting bolt 72.

  In addition, although the position adjustment mechanism 70 of this embodiment is each distribute | arranged to both of a pair of upper and lower turning members 40, you may distribute | arrange only to any one. Further, the position adjustment mechanism 70 of the present embodiment is disposed on the turning member 40 side, but may be disposed on the fixed member 50 side. In this case, the adjustment nut 71 is fixed to the right wall portion 51 of the fixing member 50, and the adjustment bolt 72 is rotatably screwed to the adjustment nut 71. In this case, when the operation panel 10 is at the home position, the adjustment bolt 72 protrudes from the right wall portion 51 toward the vertical portion 41 and contacts the vertical portion 41. As a result, the vertical portion 41 is restricted from turning in the direction toward the right wall portion 51. The position of the operation panel 10 when the adjustment bolt 72 abuts on the vertical portion 41 is the home position. The home position of the operation panel 10 can be adjusted by changing the protruding amount of the adjusting bolt 72, and the protruding amount of the adjusting bolt 72 can be adjusted by rotating the adjusting bolt 72.

  As described above, the injection molding machine according to the present embodiment includes the turning member 40, the fixing member 50, and the fastening bolt 60. The turning member 40 turns together with the operation panel 10, and the fixing member 50 is fixed to the support member 20. The fastening bolt 60 fastens the turning member 40 and the fixing member 50 when the operation panel 10 is at the home position. Since the turning member 40 and the fixing member 50 are fastened instead of fastening the operation panel 10 and the support member 20, the degree of freedom of the direction of the fastening bolt 60 is high. Therefore, the direction of the fastening bolt 60 can be set so that the operation of fixing the operation panel 10 to be unrotatable at the home position is facilitated. Further, the swivel member 40 can be arranged behind the operation panel 10 and the fixing member 50 can be arranged behind the support member 20, and the fastening bolt 60 and the like can be hidden from the operator 2 standing in front of the operation panel 10. it can.

  According to the present embodiment, when the operation panel 10 is in the retracted position, the swing member 40 and the fixed member 50 come into contact with each other, so that the operation panel 10 rotates in the direction opposite to the direction from the retracted position toward the home position. Is limited. The turning member 40 and the fixing member 50 are used for the purpose of limiting the turning range in addition to making the operation panel 10 unturnable at the home position. The turning member 40 and the fixing member 50 can have a plurality of functions, and the number of parts can be reduced.

  Moreover, the injection molding machine of this embodiment has the position adjustment mechanism 70 which adjusts a home position. Therefore, it is possible to widen an allowable range such as a dimensional error or a mounting error of the turning member 40 or the fixing member 50.

  Further, when the operation panel 10 is in the home position, the fastening bolt 60 of the present embodiment is parallel to the rear surface 11 of the operation panel 10, and the turning member 40 and the fixing member 50 are connected in a direction parallel to the rear surface 11. Conclude. The fastening bolt 60 is horizontal, for example, and the head 62 of the fastening bolt 60 is turned sideways (rightward in FIG. 2). Compared with the case where the fastening bolt 60 is perpendicular to the rear surface 11 of the operation panel 10 and the head 62 of the fastening bolt 60 is rearward, the operator who rotates the head 62 does not have to return the wrist. Good sex.

  The fastening bolt 60 of the present embodiment is parallel to the rear surface 11 of the operation panel 10 and is horizontal, but may not be horizontal, for example, vertical. In this case, the head 62 of the fastening bolt 60 is directed upward or downward. Also in this case, the operator who rotates the head 62 does not have to return the wrist, and the workability is good.

  The fastening bolt 60 of the present embodiment is parallel to the rear surface 11 of the operation panel 10, but may be inclined to the rear surface 11 of the operation panel 10. Also in this case, workability is better than when the fastening bolt 60 is perpendicular to the rear surface 11 of the operation panel 10 and the head 62 of the fastening bolt 60 is facing backward.

[Second Embodiment]
FIG. 5 is a view showing a main part of an injection molding machine according to the second embodiment of the present invention, and is a view of the operation panel as viewed from the front. 6 is a cross-sectional view taken along line VI-VI in FIG. In FIG. 6, the operator 2A is shown for convenience of explanation. FIG. 7 is a cross-sectional view showing a state where the operation panel has moved from the home position shown in FIG. 6 to the retracted position. 8 is a cross-sectional view taken along line VIII-VIII in FIG. In FIG. 8, the operator 2A is shown for convenience of explanation. FIG. 9 is a cross-sectional view showing a state where the operation panel has moved from the home position shown in FIG. 8 to the retracted position.

  The injection molding machine includes an operation panel 10A, a support member 20A, a coupling tool 30A, a first turning member 40A, a first fixing member 50A, a fastening bolt 60A (see FIG. 6) as a fastening tool, a second turning member 140A, and a second turning member. 2 fixing members 150A and the like. The injection molding machine of the present embodiment does not have a position adjustment mechanism that adjusts the home position of the operation panel 10A, but may have a position adjustment mechanism. In the following description, “left”, “right”, “upper”, and “lower” mean directions viewed from the operator 2A standing in front of the operation panel 10A.

  Operation panel 10A accepts an input operation by operator 2A standing in front of operation panel 10A. The operation panel 10A is configured with, for example, a touch panel. The operator 2A can operate, stop, and set the injection molding machine by operating the operation panel 10A.

  The operation panel 10A can turn between a home position (the position shown in FIGS. 6 and 8) where the operation panel 10A is operated and a retracted position (position shown in FIGS. 7 and 9) retracted from the home position. Is done. The operation panel 10A is normally fixed at the home position, and is retracted to the retracted position during maintenance of the injection device disposed behind the operation panel 10A. The retreat position may be set in front of the home position.

  For example, the operation panel 10A can turn around a vertical axis. Note that the operation panel 10A may be capable of turning about a horizontal axis, and the direction of the turning center line of the operation panel 10A is not particularly limited.

  Although the operation panel 10A is basically operated at the home position, it is naturally possible to operate the operation panel 10A at a position other than the home position.

  The support member 20A supports the operation panel 10A via the first fixing member 50A, the second fixing member 150A, and the like. The operation panel 10A is disposed on the right side of the support member 20A when in the home position as shown in FIG. The first fixing member 50A and the second fixing member 150A are fixed to the support member 20A.

  The coupling tool 30A is respectively held by the first fixing member 50A and the second fixing member 150A, and connects the operation panel 10A to the support member 20A so as to be turnable between a home position and a retracted position. The connector 30A is configured with a hinge or the like. For example, a torque hinge or the like is used as the coupling tool 30A so that the operation panel 10A can be stopped at an arbitrary position between the home position and the retracted position.

  The first turning member 40A turns together with the operation panel 10A. The first turning member 40A has a parallel portion 42A parallel to the front surface 12A of the operation panel 10A. The parallel part 42A has a screw hole 43A perpendicular to the front surface 12A of the operation panel 10A. A fastening bolt 60A is screwed into the screw hole 43A.

  The first fixing member 50A is fixed to the support member 20A. The first fixing member 50A has a parallel portion 52A with which the parallel portion 42A of the first turning member 40A abuts when the operation panel 10A is at the home position. A through hole 53A is formed in the parallel portion 52A, and the fastening bolt 60A is inserted into the through hole 53A.

  When the operation panel 10A is swung from the retracted position shown in FIG. 7 to the home position shown in FIG. 6, the parallel part 42A of the first turning member 40A comes into contact with the parallel part 52A of the first fixing member 50A, and the turning is further performed. Is limited.

  When the operation panel 10A is at the home position as shown in FIG. 6, the fastening bolt 60A fastens the first turning member 40A to the first fixing member 50A so as not to turn. Thereby, operation panel 10A cannot be turned at the home position. Vibration can be suppressed when operating the operation panel 10A, and erroneous operations such as pressing twice due to vibration can be suppressed.

  The fastening bolt 60A includes, for example, a screw shaft portion 61A and a head portion 62A. The screw shaft portion 61A passes through the through hole 53A of the parallel portion 52A of the first fixing member 50A and is screwed into the screw hole 43A of the parallel portion 42A of the first turning member 40A. The head portion 62A is disposed on the front side of the parallel portion 52A of the first fixing member 50A. When the head portion 62A is rotated, the head portion 62A comes close to and comes into contact with the front side of the parallel portion 52A. When the head 62A is further rotated, the parallel part 42A is pressed against the parallel part 52A, and a fastening force is generated that fastens the parallel part 42A to the parallel part 52A so as not to turn. Thus, when the operation panel 10A is at the home position, the fastening bolt 60A fastens the first turning member 40A and the first fixing member 50A from the front of the operation panel 10A.

  When turning the operation panel 10A, the fastening bolt 60A is removed from the screw hole 43A of the parallel portion 42A of the first turning member 40A and temporarily placed on the outside of the turning path such as the first turning member 40A. For example, the fastening bolt 60A is held in a holding hole formed on the upper surface of the first fixing member 50A when the operation panel 10A is turned. This holding hole may be either a screw hole into which the fastening bolt 60A is screwed or an insertion hole into which the fastening bolt 60A is loosely fitted.

  The second turning member 140A turns together with the operation panel 10A. 140 A of 2nd turning members have the arm part 141A and the stopper part 142A. The arm portion 141A turns from one side of the turning center line L of the operation panel 10A to the opposite side. For example, as shown in FIG. 8, when the operation panel 10A is at the home position, the arm portion 141A turns from the rear side to the front side of the turning center line L of the operation panel 10A. The stopper portion 142A is provided at the distal end portion of the arm portion 141A. The stopper portion 142A extends in parallel with the turning center line L of the operation panel 10A from the distal end portion of the arm portion 141A.

  The second fixing member 150A is fixed to the support member 20A. The second fixing member 150A has a contact portion 152A with which the stopper portion 142A of the second turning member 140A contacts. The contact portion 152A is disposed on the same side as the stopper portion 142A (for example, the lower side in FIG. 5) with respect to the arm portion 141A so as not to interfere with the arm portion 141A.

  When the operation panel 10A is swung from the home position shown in FIG. 8 to the retracted position shown in FIG. 9, the stopper part 142A of the second turning member 140A comes into contact with the contact part 152A of the second fixing member 150A, and more Turn is restricted.

  As described above, the injection molding machine according to the present embodiment includes the first turning member 40A, the first fixing member 50A, and the fastening bolt 60A. The first turning member 40A turns together with the operation panel 10A, and the first fixing member 50A is fixed to the support member 20A. The fastening bolt 60A fastens the first turning member 40A and the first fixing member 50A when the operation panel 10A is at the home position. Since the first turning member 40A and the first fixing member 50A are fastened instead of fastening the operation panel 10A and the support member 20A, the degree of freedom of the direction of the fastening bolt 60A is high. Therefore, the direction of the fastening bolt 60A can be set so that the operation of fixing the operation panel 10A so as not to turn is facilitated at the home position.

  Further, the injection molding machine of the present embodiment includes a second turning member 140A and a second fixing member 150A. The second turning member 140A turns together with the operation panel 10A, and the second fixing member 150A is fixed to the support member 20A. When the operation panel 10 is in the retracted position, the second turning member 140A and the second fixing member 150A come into contact with each other, thereby restricting the turning of the operation panel 10 in the direction opposite to the direction from the retracted position toward the home position. The

  Further, the second turning member 140A of the present embodiment has an arm portion 141A and a stopper portion 142A. When the operation panel 10A is swung from the home position shown in FIG. 8 to the retracted position shown in FIG. 9, the stopper part 142A of the second turning member 140A comes into contact with the contact part 152A of the second fixing member 150A, and more Turn is restricted. The stopper portion 142A is provided at the distal end portion of the arm portion 141A, and the arm portion 141A turns from one side of the turning center line L of the operation panel 10A to the opposite side. The arm portion 141A, the stopper portion 142A, the contact portion 152A, and the like are gathered around the turning center line L of the operation panel 10A, and a space secured for these is small. As a result, the turning angle of the operation panel 10A from the home position to the retracted position can be set large. This is particularly effective in a small injection molding machine. This is because in the case of a small injection molding machine, it is necessary to swivel the operation panel greatly in order to secure a work space during maintenance of the injection device.

  The arm portion 141A and the stopper portion 142A of the present embodiment are applied to the second turning member 140A, but may be applied to the first turning member 40A. Further, the arm portion 141A and the stopper portion 142A may be applied to the turning member 40 of the first embodiment.

  Further, the second turning member 140A and the second fixing member 150A of the present embodiment are disposed between the operation panel 10A and the support member 20A when the operation panel 10A is at the home position, for example, as shown in FIG. Is done. The turning limiting mechanism including the arm portion 141A, the stopper portion 142A, the contact portion 152A, and the like can be collected around the turning center line L of the operation panel 10A.

  The fastening bolt 60A of the present embodiment fastens the first turning member 40A and the first fixing member 50A from the front of the operation panel 10A when the operation panel 10A is at the home position.
