Abstract

A display system includes: an imaging unit that images a mold from below; and a display unit that displays an image taken by the imaging unit together with a carry-in range of the mold in order to transport the mold in place between the stationary platen and the moving platen.

First claim

What is claimed is:

1. A display system for displaying a state of a mold being transported from above into a space between a stationary platen and a moving platen that moves in a predetermined direction relative to the stationary platen in a clamping device, comprising:
an imaging unit provided between and below the stationary platen and the moving platen and configured to image the mold from below, together with obstacles that may interfere with the mold, the obstacles including the stationary platen, the moving platen, and tie bars that guide the moving platen to move relative to the stationary platen; and
a display unit configured to display an image taken by the imaging unit together with a carry-in range of the mold in order to transport the mold in place between the stationary platen and the moving platen.

2. The display system according to claim 1 , wherein the display unit is configured to display the carry-in range having a size corresponding to a distance from the imaging unit to a predetermined position located along the transporting direction.

3. The display system according to claim 2 , wherein the display unit is configured to display a plurality of carry-in ranges simultaneously each having a size corresponding to one of distances from the imaging unit to a plurality of predetermined different positions located along the transporting direction.

4. The display system according to claim 1 , further comprising a distance measuring unit comprising a distance measuring sensor provided below the mold and configured to measure the distance to the mold, wherein the display unit is configured to display the carry-in range having a size corresponding to the distance that is from the distance measuring unit to the mold and measured by the distance measuring unit.

5. The display system according to claim 4 , wherein the distance measuring unit is provided in the imaging unit, on an upper surface of the stationary platen, or between the stationary platen and the moving platen.

6. The display system according to claim 1 , wherein the imaging unit is provided on an upper surface of the stationary platen.

7. The display system according to claim 1 , wherein imaging unit is provided between and below the stationary platen and the moving platen and configured to image the mold together with obstacles that may interfere with the mold, the obstacles including the stationary platen, the moving platen, and tie bars that guide the moving platen to move relative to the stationary platen.

8. The display system according to claim 1 , further comprising a driving unit comprising a driver configured to move the moving platen relative to the stationary platen so as to vary a distance between the moving platen and the stationary platen, wherein the display unit is configured to change a size of the carry-in range to be displayed according to the distance between the moving platen and the stationary platen.

9. A display method of displaying a state of a mold being transported from above in a space between a stationary platen and a moving platen that moves in a predetermined direction relative to the stationary platen in a clamping device, comprising:
an imaging step of imaging the mold from below by an imaging unit, wherein the imaging step is performed such as to image the mold together with obstacles that may interfere with the mold, the obstacles including the stationary platen, the moving platen, and tie bars that guide the moving platen to move relative to the stationary plate; and
a displaying step of displaying on a display unit the taken image together with a carry-in range of the mold in order to transport the mold in place between the stationary platen and the moving platen.

10. The display method according to claim 9 , wherein the displaying step is performed such as to display the carry-in range having a size corresponding to a distance from the imaging unit to a predetermined position located along the transporting direction.

11. The display method according to claim 10 , wherein the display step is performed such as to display a plurality of carry-in ranges simultaneously each having a size corresponding to one of distances from the imaging unit to a plurality of predetermined different positions located along the transporting direction.

12. The display method according to claim 9 , further including a distance measuring step of measuring the distance to the mold by means of a distance measuring unit, wherein the displaying step displays the carry-in range having a size corresponding to the distance that is from the distance measuring unit to the mold and measured by the distance measuring unit.

13. The display method according to claim 9 , wherein the imaging step is performed such as to image the mold together with obstacles that may interfere with the mold, the obstacles including the stationary platen, the moving platen, and tie bars that guide the moving platen to move relative to the stationary platen.

14. The display method according to claim 9 , further comprising a driving step of moving the moving platen relative to the stationary platen by means of a driving unit to vary a distance between the moving platen and the stationary platen, wherein the displaying step changes a size of the carry-in range to be displayed according to the distance between the moving platen and the stationary platen.
