Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveying device for conveying a cylindrical object, such as a cylindrical mold.

0002

[Prior Art] For example, in the manufacturing process of rubber belts,
After the cylindrical unvulcanized belt material is wrapped around a mold and inserted into a vulcanization can and cured, the vulcanized rubber molded product (called a slab) is cooled or cooled. Operations such as extracting the subsequent slab from the mold and applying a mold release agent to the outer peripheral surface of the mold after the slab has been extracted are performed in sequence. In this case, conveyance of the mold between each of these work processes has conventionally been carried out mainly manually by an operator. That is, conventionally, an operator operated a crane to suspend the mold and transported it to the next process, or an operator placed the mold on a trolley and then transported it to the next process using the trolley.

0003

However, in the above-mentioned conventional conveying method, much of the work is done manually by the operator, and in particular, the operator has to directly touch the mold, which places a heavy burden on the operator. In addition, the temperature of the mold (including the surrounding rubber molded product) immediately after vulcanization is extremely high, and the cylindrical mold tends to roll when it falls over, so there is a problem with work safety. Furthermore, each time the mold is transported between the respective work steps, the operator is required to operate a crane, load and unload the mold onto a trolley, and the transport efficiency is also poor.

[0004] The present invention has been made in view of the above points.
The transportation of molds, etc. between each work process is automated,
The purpose of the present invention is to provide a conveyance device for cylindrical molds, etc., which eliminates the need for manual labor by workers, improves work safety, and has high conveyance efficiency.

[0005]

[Means for Solving the Problems] In order to achieve the above-mentioned objects, the conveyance device of the present invention provides: a) a device for horizontally conveying a cylindrical mold, etc. along a conveyance base such as a roller or a slide table; b) a movable member disposed movably parallel to the conveyance base and moved by a movable mechanism; and c) movable member disposed movably tiltable in the vertical direction with respect to the movable member and held in a horizontal state by a cylinder mechanism. and d) a tilting member that is held in an upwardly inclined state, and d) is provided so as to protrude toward the conveyance base with respect to the tilting member, and is movable toward and away from each other in parallel with the conveyance base by a feeding mechanism. and a pair of clamp members arranged therein.

[0006]

[Operation] According to the conveying device of the present invention having the above-mentioned configuration, in a state where the mold is placed at a predetermined position on the conveying base, (1) the moving mechanism moves the pair of clamp members together with the moving member; Move until the mold is in the middle of the parts. At this time, the pair of clamp members are pulled up and held together with the tilting member by the cylinder mechanism. Note that the distance between the pair of clamp members is adjusted in advance by a feeding mechanism so that it is wider than the width of the mold. ■When the cylinder mechanism extends and the tilting member becomes horizontal, a pair of clamp members descend to both sides of the mold. (2) The feeding mechanism causes the clamp members to approach and close the mold, thereby clamping the mold. (2) The clamp member is moved together with the moving member by the moving mechanism, and the mold held by the clamp member is transported to a predetermined location along the transport base. Thereafter, the clamp members are separated from each other by the feeding mechanism, and the clamp members are pulled upward together with the tilting member by the cylinder mechanism and held.

Further, a locking fitting 11 is attached to the lower end of the slide frame 6.
A locking piece 11a that can be locked is attached. With this configuration, when the drive pulley 7 is rotated by the motor 7a, the endless belt 10 rotates and the locking fitting 11 engages with the locking piece 11a of the slide frame 6, so that the slide frame 6 moves in one direction. .

As shown in FIG. 4, a stopper bracket 12 is provided at approximately the center of the lower end of the slide frame 6 to protrude forward (toward the roller conveyor 2 side). A tilting frame 13 as a tilting member is placed horizontally on this stopper bracket 12. A hanging bracket 14 is fixedly installed in the center of the tilting frame 13, and the tip of a piston rod 15a of an air cylinder device 15, which is pivotally supported at the upper end of the slide frame 6 via a bracket 16, is connected to the hanging bracket 14. has been done. With this configuration, when the piston rod 15a of the air cylinder device 15 is contracted, the tilting frame 13 is tilted upward, and when the piston rod 15a is extended to the maximum, the tilting frame 13 is placed horizontally on the stopper bracket 12.

On the tilting frame 13, as shown in FIG. 1, a pair of linear motor guides 17 and 18 are arranged in parallel in the longitudinal direction with an interval between each linear motor guide 17 and 1.
A pair of clamp arms 19, 19 can be moved freely along the line 8.
is installed. The clamp part 19a at the tip of each clamp arm 19 protrudes forward (to the roller conveyor 2 side), and the left and right opposing clamp parts 19a are attached to the cylindrical mold A.
They are each formed in a dogleg shape corresponding to the circumferential surface of. Note that a cushioning material is attached to the surface of each clamp portion 19a so as not to damage the mold A.

Next, the piston rod 15a of the air cylinder device 15 is extended, and the tilting frame 13 is placed horizontally on the stopper bracket 12, and at the same time, the clamp portions 19a of the pair of clamp arms 19 are placed on both sides of the mold A. descend.

Next, the motor 20a starts rotating and the feed screw rod 20 rotates in a predetermined direction, so that the pair of clamp parts 19a approach and close the mold A, thereby clamping the mold A. . Here, the motor 7a starts rotating in the opposite direction, and the endless belt 10 runs in the conveying direction of the mold A, and the pair of clamp arms 1 and the slide frame 6 move together.
9 moves, and the mold A held by the clamp portion 19a is conveyed along the roller conveyor 2 to a predetermined location.

After this, the feed screw rod 2 is moved by the motor 20a.
0 rotates in the opposite direction, the pair of clamp arms 19 are separated from each other, and the clamp portion 19a is opened, and further, the clamp arm 19 is moved upward together with the tilting frame 13 due to the contraction of the piston rod 15a of the air cylinder device 15. Raised and held. Subsequently, the endless belt 10 is rotated by the motor 7a, and the clamp arm 19 together with the slide frame 6 returns to the original standby position. Note that when the sensor detects that the next mold A is already placed at a predetermined position on the roller conveyor 2, the clamp arm 19 returns to the position of the mold A. Further, the mold A that has been transported to a predetermined location is cooled there by, for example, a cooling device (not shown).

In this way, the mold A is automatically transported to a predetermined location and the next operation is performed, but when the operation is finished, the mold A is returned to the conveying device 1 in the same manner as described above. It is transported to the next working position by the installed transport device 1.

In the above embodiment, the mold A is transported to the next process by one transport device 1, but by extending the movement range of the transport device 1, the mold A is transported by one transport device 1. The material may be sequentially transported to a plurality of processes (work positions). Further, in the above embodiment, a case where a cylindrical mold A is transported is illustrated, but the object to be transported is not limited to the mold A.
