Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a transfer attitude conversion structure for converting the transfer attitude of a round workpiece transferred from an inclined transfer chute.

[0002]

[Prior art]

 For example, when a cylindrical work such as a sleeve that is cast into an engine cylinder block is transported and supplied to a machining process, the work is usually performed by rolling the work using an inclined transport chute. Depending on the knitting, it may be necessary to change the posture of the work by 90 ° and convey and supply the work.

Therefore, conventionally, in such a case, a rotating member for placing and rotating a work is provided at a portion where the transfer chute intersects, and the work is temporarily stopped on the rotating member during the transfer, and then the rotating member is used. A method is adopted in which the transfer posture of the work is converted by 90 ° by rotating the.

[0004]

[Problems to be solved by the device]

 However, in the case of changing the transfer posture of the work as described above, a drive source such as a motor for rotating the rotating member is necessary, and moreover, the rotating member is rotated in order to set the rotating timing of the rotating member. In addition to the need for a sensor to detect that the work is placed on the workpiece, the work cannot be supplied until the rotary member returns to its original position after changing the posture, which is a waste of time. there were.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a lower transfer chute for transferring a post-position change work below the transfer end part of an upper transfer chute for transferring a work, and at the transfer end part of the upper transfer chute. Is a first guide member that curves downward in the transfer direction and guides one end of the workpiece, and a second guide member that curves downward in the direction opposite to the transfer direction and guides the other end of the work. And the end of the second guide member is located above the end of the first guide member.

[0006]

[Action]

 The work transferred through the upper transport chute falls between the first guide member and the second guide member near the transfer end portion, and one end thereof is guided by the first guide member whose end is lower, The second guide member guides the other end to change the posture, and the lower guide chute is transferred.

【Example】

 An embodiment of a work transfer posture changing structure of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of a work posture changing structure according to the present invention, FIG. 2 is a plan view of FIG. 1, and FIG. 3 is a side view of FIG.

The work transfer posture changing structure of the present invention is a jig for converting the posture of a work W having a round shape such as a cylindrical sleeve cast into a cylinder block of an engine by about 90 degrees and transferring the work. As shown in FIG. 1, the upper transport chute 1 and the lower transport chute 2 are provided.

That is, the upper transport chute 1 has a groove shape that restricts both ends of the round work W, and is arranged so as to be inclined so that the work W rolls by its own weight. A groove-shaped lower conveyance chute 2 that crosses the upper conveyance chute 1 at a substantially right angle and transfers the work-changed work W is disposed in the lower part of the vicinity in an inclined manner.

An opening 3 is formed at the transfer end of the upper transport chute 1, and a rod-shaped first guide member 4 and a second guide member 5 are provided in the opening 3.

The first guide member 4 is attached to an end portion of the bottom plate 6 of the upper transport chute 1, bends downward in the transfer direction of the work W, and guides one end of the work W.

The second guide member 5 is attached to the side plate 7 on one side extending further from the bottom plate 6 and curved downward in the direction opposite to the transfer direction of the work W, and the other end of the work W is proposed. It is possible within. Further, as shown in FIG. 3, the end of the second guide member 5 is located above the end of the first guide member 4.

In the posture changing structure configured as described above, when the work W transferred in the upper transport chute 1 reaches the opening 3 at the transfer end portion of the upper transport chute 1, the first guide member 4 is moved. Between the first guide member 4 and the second guide member 5, the one end portion side of the first guide member 4 advances ahead of the other end portion side.

Then, when the other end of the work W comes into contact with the second guide member 5, the posture of the work Wa has already been tilted as shown in FIG. 2, and the first guide member material with inertia is formed. The one end on the 4 side further advances faster than the other end to convert the posture by 90 degrees. That is, during this period, the work W is in a state of pivoting about the second guide member 5 side.

The end of the second guide member 5 is located higher than the end of the first guide member 4, and the one end of the work W on the side of the first guide member 4 advances rapidly. Almost at the same time that one end side of the work W on the side of the first guide member 4 having a high traveling speed moves away from the first guide member 4, the other end side of the work W moves away from the second guide member 5 to change the posture by 90 degrees. Then, it falls into the lower transfer chute 2. As described above, the posture of the work W is naturally changed during the transfer process.

[0016]

[Effect of device]

 As described above, according to the present invention, the first guide member and the second guide member for guiding the end portion of the work are arranged opposite to each other at the transfer end portion of the upper conveyance chute in the opposite direction. The posture is changed in the process of falling from the upper conveyance chute to the lower conveyance chute in the transfer process, and the posture can be changed with a simple structure and in an extremely short time. Moreover, such a structure has a simple structure and is inexpensive.
