JPS63134133A - Chucking type transfer and carriage device for speaker frame for speaker assembly - Google Patents

Abstract

PURPOSE:To shorten a frame carriage pitch and reduce transfer time by moving a chucking tool from a standby position backward under a receiver to a holding position forward above the receiver for chucking a frame. CONSTITUTION:Chucking tools 5 are brought close to each other until a predetermined position via a distant adjustment drive device 7. In this case, the chucking tools 5 are kept at standby positions backward under a receiver 12, due to the downward motion of the cylinder of a chucking tool drive device 8. When the chucking tools 5 have been brought close to a frame (work), the cylinder of the drive device 8 moves upward and the tools 5 are turned up to positions under the receiver 12 and come in contact with a side frame, thereby being stopped to turn. And the cylinder has been further moved upward, and the chucking tools 5 located under the receiver 12 move upward concurrently therewith, thereby holding and transferring the frame with the receiver 12. Therefore, it is unnecessary to separate the chucking tools 5 to a maximum stroke whenever the frame is transferred, and the pitch of frame transfer can be made small.

Description

Detailed Description of the Invention <Industrial Application Field> The present invention relates to a pick-up type transfer device for speaker frames for assembling speakers within a predetermined assembly block, and the present invention relates to a pick-up type transfer device for speaker frames for assembling speakers within a predetermined assembly block. To provide something that can be transferred to a line at the correct position without wobbling.

<Prior Art> The basic structure of the speaker frame grab-type transfer device, which is the object of the present invention, is as shown in FIG. 1 or 5.
A transfer frame 2 is movably supported in the horizontal direction by a horizontal movement device 3 and in a vertical direction by a vertical movement device 4 relative to the support frame 1, and a plurality of speaker frame grabbers 5 are gripped and operated on the transfer frame 2. The device 6 is of a type in which the speaker frames are supported so that they can be moved horizontally toward and away from each other and can be gripped and operated.

In this type of conventional technology, as shown in Japanese Utility Model Application Publication No. 58-99999 (see FIG. 5), a drive motor (not shown) and a gear 101 attached to a drive shaft 100 mesh with the gear 101 and oppose each other. A pair of racks 10 moving in the direction
2 and 103 constitute a karakami retracting device 6, and a flat cross-section dog-shaped gnashing soldier 5 is fixed so as to be movable together with each of the above-mentioned racks 102 and 103, and a pair of gripping tools are formed by rotation of a drive motor. There is one in which the speakers 5 are moved closer to each other and further away from each other so that they sandwich the speaker frame from the left and right sides.

<Problem that the invention seeks to solve> The above conventional technology has the following problems.

(1) The size of the speaker frame varies depending on the type of speaker, and when grasping the frame, the distance between the grips 5 is set to be larger than the diameter of the large frame so that the frame can be held smoothly.

For this reason, when moving away to grab a predetermined frame, the transport pitch of the frame is ensured to be larger than the moving distance required for the grabbing soldier 5 to separate so that the grabbing soldier 5 does not hit the next frame. have to,
The conveyance line becomes long.

(2) In the support-holding operation, among the four contact points where the pair of dogleg-shaped grips try to pinch and contact the speaker frame, one contact remains after three contact points come into contact. Since the points do not make sufficient contact, the sandwiched speaker frame may wobble and the center of the frame may shift.

This problem is more likely to occur in the case of irregularly shaped frames such as oval or square frames.

In addition, when performing clipping and holding exercises, hold the outer periphery of the frame and
If the outer periphery of the frame is originally eccentric from the center hole of the frame, the center hole of the frame will shift from the center position of the pallet when the outer periphery of the frame is held.

As a result of these two factors, when the pallet is transferred to the next conveyor line, the center of the frame shifts from the center of the pallet, making it impossible to position it correctly.

(3) Regardless of the size of the frame, for example, even in the case of a small frame, the gripping tool must be driven to the maximum stroke, which increases the time required for transferring one frame.

(4) Since the frame is held and held from the left and right sides, there is no particular problem with a metal frame, but with a synthetic resin frame, there is a risk that the shape of the frame may be deformed.

The technical problem of the present invention is to reduce the conveyance pitch of the frame, transfer the frame to the correct position, and shorten the time required for the transfer.

<Means for Solving the Problems> Means for achieving the above problems will be described below with reference to FIGS. 1 to 4, which correspond to embodiments.

Specifically, in the present invention, the gripping device 6 is composed of a perspective adjustment drive device 7 and a gripping device driving device 8, and a plurality of gripping device support frames 10 are horizontally aligned with each other on the transfer frame 2 by the perspective driving adjustment device 7. The grip support frame 10 is provided with a receiver 12 facing downward, and the speaker frame gripper 5 is supported on the grip support frame 10, and the speaker frame gripper 5 is gripped and driven together. Receiver 1 with device 8
2. The standby position A and the receiver 12 retreat to the rear from the lower space of 2.
The gripping position B is characterized in that the gripping position B is switched from the lower space to the gripping position B, which approaches the receiver 12 upwardly.

<Function> At the time of setup change, the distance adjustment drive device 7 of the grip support frame 10 is operated to adjust the distance of the pair of grips 5 in the horizontal direction to match the diameter of the speaker frame.

When assembling the speaker, the gripper driving device 8 is operated to move the gripper 5 from the standby position A at the lower rear of the receiver 12 to the gripping position B located at the front and upper side, and the speaker frame is moved from the gripper 5 to the gripper 5. and the receiver 12, and transfer it to a predetermined position.

In addition, the frames transferred by the above-mentioned transfer device include not only a single frame, but also a frame and a plate fixed together,
Alternatively, an integrated structure including a yoke and a magnet may be further fixed to this integrated structure.<Effects of the invention> After finishing, when assembling the speaker, by repeating the basic operation of advancing and raising the grip from the standby position and moving it to the grip position, the speaker frame can be transferred and removed one by one, unlike the conventional technology. In addition, even after a setup change, there is no need to carry out the work of separating the grips to the maximum stroke every time they are transferred, and even if the frames are conveyed close together, the grips in the standby position will not move until the next time. There is no need to worry about being hit by a frame that is flowing in.

Therefore, the conveying pitch of the frames can be reduced, thereby making it possible to downsize the conveying device and make effective use of space.

(2) Both sides of the flange of the speaker frame are clamped from above and below by grippers and receivers, so the frame is securely clamped and fixed without wobbling (1 degree, and when clamped from above and below). , the center of the frame is shifted from the center of the pallet and cannot be moved.

Thereby, when the frame is transferred, the center of the frame is accurately aligned with the center of the pallet.

(3) After completing the adjustment in the radial direction at the time of setup change, when assembling the speaker, simply move the grips between the standby position and the grip position using the grip drive device, and the left and right This saves the effort of separating the grabber to the maximum stroke (in particular, the frame is the part with the largest diameter among the speaker parts, and in conventional transfer operations, the separation stroke is the longest). Ta)
.

Therefore, the clamping/unclamping time can be shortened, the transportation time can be shortened, and the productivity of the speaker can be improved.

(4) This transfer device transfers the frame by holding it between the upper support and the lower grip from above and below, so unlike the conventional technology which holds the frame in a pressing manner from the left and right, the frame is not forced to deform. No force is applied, and even resin frames can be prevented from deforming.
