Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hanger in a hanger conveyance system used for conveying sewn product workpieces, etc.

[Prior Art] A hanger conveyance system that conveys articles manually, by gravity, or by frictional engagement of a circulating belt using a hanger suspended from an overhead rail using a support pulley is used, for example, in a garment factory. It is frequently used to transport sewing workpieces between each process station.

FIG. 5 shows an example of a conventional hanger used in this type of conveyance system. R is a guide roller running on an overhead hanger rail (not shown), and is supported so as to freely rotate on a horizontal axis at the top of the hanging hanger rod H.
An inverted U-shaped member U is attached to the lower end of the rod H, either fixedly or pivotably around a vertical axis, a clamp block B is fixedly attached to one end of the leg of the member, and a finger member is attached to the other end. F is rotatably attached by a pin P. The abutting parts of the weight members B and F abut at an appropriate wedge angle with respect to the vertical direction, and the abutting surfaces of both have frictional force with the sewn product work W (not shown) to be held/suspended. In order to increase this, unevenness such as stripes or waves is formed, and an opening/closing type work clamping device C is formed, which is biased by a torsion coil spring S so as to be in constant contact.

There are various types of these open/close type clamps, and some have a small clip K for use with process slips and other documents attached downward to the hanger rod H section. In addition, a so-called multi-type special hanger is also used, which has a plurality of clamp parts at the lower part of the hanger rod H.

[Problems to be solved by the invention] However, in the commonly used single-clamp type hanger as shown in Fig. 5, it is necessary to operate the opening/closing mechanism (finger F, etc.) of the clamp C each time a workpiece to be hung is attached or detached. Even in the above-mentioned type of hanger equipped with a small downward-facing clip K, the main purpose of the clip K is to transmit the above-mentioned slips and small parts together with the main work. The operations for attaching and detaching the workpiece using the fingers F of the clamp section are exactly the same as described above.

Furthermore, what is important in the actual sewing process is, for example, as shown in FIGS. 6a and 6b,
The packing style, gripping width, gripping thickness, weight, etc. of the workpiece w to be hung on a hanger, from fabric _w1 to semi-finished products/finished goods _w2 , etc., change as the process progresses at each sewing station. If the clamp mechanism is of only one type, it is difficult to adapt to the above-mentioned changes, and unnecessary effort and time are required for attachment and detachment.

The present invention was devised in view of the problems of the conventional examples as described above, and aims to provide a hanger for transporting workpieces of this type that has a simple structure and can accommodate changes in the appearance of workpiece packaging as the process progresses. The purpose is

[Means for Solving the Problems] Therefore, the present invention attempts to achieve the above object by providing a hook-type hanging device on a part of the hanger.

[Function] With the configuration described above, in addition to the conventional opening/closing type clamping device, it can be used in response to changes in the packing form and weight of the workpiece, as well as the so-called one-hand type clamping device, making it possible to attach/remove various types of workpieces. becomes easier.

[Examples] The present invention will be described below based on Examples.
FIG. 1 is an overall perspective view of an embodiment of the hanger assembly for transporting workpieces according to the present invention, and FIG. 2 is a front view (partially sectional view) of the main parts thereof, which is the same as FIG. 5 of the conventional example. (Equivalent) Components are represented by the same symbol.

(Structure) In Figs. 1 and 2, 1 is a part in which most of the upper part of the hanger rod part is formed of a pipe-shaped hollow rod member Ha, which is attached to the hanger rod part H which is fixed (or pivoted) to the inverted U-shaped member U. The configuration is shown in which the holder is inserted into the holder and fixed in an expandable and retractable manner using machine screws 3. A so-called "hat hook"-like hook type hanging tool 1 with a smooth enlarged tip portion is fixedly mounted on the hollow barrel member Ha in an appropriate circumferential direction.
Further, in the illustrated example, two upwardly directed spring type clips 2 are attached as a modification of the above-mentioned hanging device.
Furthermore, a downward spring-type clip 2a is fixedly attached to one leg of the inverted U-shaped member U.

(Operation) As is obvious from the above configuration, when the workpiece is cloth, the conventional open/close type clamp device C
When the sewing process progresses and the workpiece reaches a form suitable for hanging, it is hung on the hook-type hanging tool 1 with one hand. The state at this time is shown in FIG. W ₃ shows an example of a jacket in near-finished condition.

Further, when the posture/weight of the workpiece is suitable for hooking with the spring-type clip 2, use the spring-type clip 2 as appropriate. In this case as well, it is extremely easy to attach and detach because it can be operated with one hand, and since it faces upward, there is no risk of it falling off during transportation. In some cases 1 or 2
Of course, both members may be used at the same time.

Furthermore, the downwardly disposed spring type clip 2a is conveniently used for documents such as process sheets or small items.

(Other Embodiments) In the above embodiments, the hanger rod was composed of a hollow rod member Ha and a solid rod member H, but the hook type hanging tool 1 or the spring clip 2 to be attached according to the present invention is Of course, it is also possible to configure the actual rod H only and attach it directly thereon.

Further, the hook shape of the hanging tool 1 is not limited to the above-mentioned shape as long as it can be operated with one hand depending on the target workpiece, as shown in three examples in FIGS. 3a, b, and c. Of course, the shape/size of the spring type clips 2, 2a also conforms to this.

[Effects of the invention] As described above using the embodiments, according to the invention, the gripping/suspension of the workpiece can be carried out using an opening/closing clamp device or a one-hand operation hook-type suspension according to the characteristics of the workpiece. Since it can be used for different lowering tools, work efficiency can be improved in response to the variety of workpieces.
