As shown in FIGS. 1 and 2, a suction transfer apparatus 10 according to an embodiment of the present invention is attached to a gantry 11 having a sufficient height and a carriage 12 traveling on the gantry 11 so as to be movable up and down. The lift 13 and the two suction means 14 and 15 attached to the lift 13 are provided. These will be described in detail below.
The gantry 11 is made of a steel member, has a pillar 17, a traveling rail 18 is disposed on the front and rear beams, and a carriage 12 having wheels 19 and 20 travels thereon. The wheel 19 is rotationally driven by a drive motor 21a, so that the carriage 12 is self-propelled.
The elevator 13 is mounted directly below the carriage 12 so that it can be raised and lowered. As the lifting means, a winch may be arranged on the carriage 12, the four corners of the lifting base 13 may be hung with a rope, and the rope may be wound with the winch, or the four corners of the lifting base 13 may be externally threaded rods. It is also possible to suspend a nut that is screwed onto the male screw rod and to be arranged on the carriage 12 so that the nut can be rotated by a motor.
[0007]
As shown in FIG. 1, two suction means 14 and 15 are attached to the lift 13 so as to be lifted and lowered. The suction means 14 and 15 include upper fixing members 14a and 15a that are rectangular in plan view, and lower suction pads 14b and 15b that are supported by the fixing members 14a and 15a and are rectangular in plan view. 15a, a pair of guide rods 21 and 22 and upper and lower locking means 23 and 24 arranged at the center thereof are provided. The guide rods 21 and 22 are moved up and down through the lifting platform 13, and the lock means 23 and 24 lock the vertical movement of the support rods 25 and 26 protruding downward by a predetermined electric signal. . The elevator 13 is provided with sensors 27 and 28 for detecting the guide rods 21 and 22.
As described above, the suction means 14 and 15 include the fixing members 14a and 15a and the suction pads 14b and 15b joined to the fixing members 14a and 15a. As shown in FIGS. 15 b is made of rubber that does not have air permeability (eg, sponge rubber, urethane rubber), and has a linear vacuum suction port 29 in the center, and the fixing members 14 a and 15 a are wires communicating with the vacuum suction port 29. A vacuum vent 30 is provided.
[0008]
The length of the vacuum suction port 29 is preferably about 2 to 3 times the pitch of the protruding ribs 32 formed in a lattice pattern on the bottoms 36 and 37 of the molded product 31 (see FIGS. 5 and 6). Thereby, the plurality of spaces 33 formed by the protruding ribs 32 can be covered.
Fixing member 14a, on the upper surface of 15a, as described above, the lower end of the guide rods 21, 22 and the support rods 25, 26 are fixed, as shown in FIGS. 4 and 5, the vacuum vents A nipple 34 that communicates with 30 is attached to which the tip of a vacuum hose 35 is connected.
The molded product 31 is formed of a lightweight member such as plastic, and has two bottom portions 36 and 37 which are suctioned portions in the vertical direction on the back side, and protruding ribs 32 are provided in a lattice shape on each, As described above, the plurality of space portions 33 are surrounded by the protruding ribs 32. Reference numeral 38 denotes a mounting table.
[0009]
Then, operation | movement and an effect | action of this adsorption transfer apparatus 10 are demonstrated.
The carriage 12 traveling on the gantry 11 is moved to a position directly above the molded product 31 to be pulled up, and the elevator 13 is gradually lowered using the elevator means. In this state, the suction means 14 and 15 shown in FIG. 1 are lowered to the bottom, and the sensors 27 and 28 do not detect the guide rods 21 and 22, respectively.
The suction means 14 comes into contact with the bottom portion 36 of the molded product 31 by the lowering of the lifting platform 13. If the descent of the elevator 13 is further continued in this state, the guide rod 21 protrudes from the upper part of the elevator 13 so that the sensor 27 is activated. When the elevator 13 is further lowered, the other suction means 15 comes into contact with the bottom portion 37 of the molded product 31 as shown in FIG. When the elevator 13 is further lowered in this state, the guide rod 22 is raised and the sensor 28 is activated, so that the operation of the sensors 27 and 28 is confirmed and the elevator 13 is stopped. Next, when the vacuum solenoid valve connected to the base side of the vacuum hose 35 is opened and the vacuum pump is driven, the suction pads 14 b and 15 b are attracted to the bottom portions 36 and 37 of the molded product 31.
[0010]
This will be described in detail. As shown in FIG. 6, the hatched space portion of the space portion 33 surrounded by the protruding rib 32 is vacuum-sucked. In this case, the surrounding protruding ribs 32 prevent air from leaking. Since only the space portion 33 where the vacuum suction port 29 is located is sucked, the length and the forming position must be determined in advance in consideration of all types of molded products.
In this state, the lock means 23 and 24 are operated to lock the support rods 25 and 26, and the elevating means is operated to raise the elevating table 13 gradually. Since the molded product 31 is vacuum-sucked by the suction pads 14b and 15b, it rises as it is. After raising / lowering the molded product 31 to a predetermined position, the carriage 12 is laterally fed to convey the molded product 31 to the predetermined position.
When this molded product 31 is placed at a predetermined location, the procedure is reversed.
[0011]
In the above embodiment, a molded product having a bottom portion with two different heights as a molded product has been described. However, the present invention can be applied regardless of the presence or absence of a step, and the molded product has one bottom. The present invention also applies.
[0012]
【The invention's effect】
In the suction transfer apparatus according to claim 1, the suction means corresponding to each suction site is attached to the lifting platform so as to be movable up and down, and confirms that the suction means has reached the suction site of the object. Since the locking means for stopping the vertical movement of the means is provided, it is possible to reliably convey the object even if the object has a different height of the adsorption part.
Further , the suction means includes a vacuum suction port, and includes a suction pad made of a non-breathable and elastic material, and a fixing member having a vacuum vent hole that supports the suction pad and communicates with the vacuum suction port. In addition, since the vacuum suction port of the suction pad is linearly long, it is possible to reliably suck the object having the protruding rib at the bottom.
