o 0O N

  The subject of the invention is a device for trans-

  fert of pieces cut from product holders

  suspended handling facilities, which are moved by a chain. The invention finds an application in the clothing industry, where the different sewing groups are coupled together by a suspended handling installation, and where the

  unstacking of the sewing groups is carried out automatically-

  is lying. DE-A-3509974 discloses a process for transporting textiles to processing / shaping devices, as well as

  transport for the implementation of this process. The invention

  tion aims to provide a method and a transport device for handling semi-finished products in the form of pairs of textile pieces, as soon as they are produced (cut) in a form corresponding to their shaping and processing, and thus making it possible to glue together, by machine, the pieces cut from the top fabric and its lining, during their mechanical transport, but also allowing in particular shaping and processing of these cut pieces, or sewing operations, avoiding the most

possible manual activities.

  A drawback lies in the fact that the cut pieces must still be introduced by hand into the hanging track, and that the transfer into the product holder is not directly coupled to the sewing groups, and therefore does not allow continuous automation. .

  We also know from DE-A 3524221 a device

  tif handling of pieces of clothing hanging from hangers. In this case, it is no longer necessary to have an operator for the hanger reception station and for the hanger removal station. The device comprises a transport chain with supports for clothes,

  which is provided with an automatic fixing for hangers -

  which include an adjustable fixing jaw. The hanger is designed to open automatically, under the effect of forces acting on the maintained hanger, in a hanger receiving station, located below a hanger magazine and intended to receive a hanger falling from this one, and in a hanger removal station. In this case, a serious disadvantage lies in the fact that the pieces of clothing must be hung

  on a hanger, which has the effect of hampering the handling

  tion, even when the work is done in a suspended state.

  The suspension on the hanger must continue to be done at

hand as before.

  The object of the invention is to make automatic the transfer of cut pieces in suspended handling installations, the product holder being brought into the area of the transfer station, by a corresponding transport chain, and the technical complexity of

  achievement being limited to a minimum.

  The invention proposes to automatically transfer

  a cut piece in a product holder, without

  resort to additional technical means of

  the clamping element of the product holder.

  According to the invention, this object is achieved in that the product holder of a handling installation is arranged above a transport chain in the direct transfer area and that the product holder is preferably in the chain return area. In addition, preferably two conveyor belts are arranged in a space defined with respect to each other so that this results in a slit. To stop the conveyor belt, a cut-out detector is provided. A blade is fixed directly behind a

  cutting edge with corresponding guide members

  dants, suspensions and training. To prevent the product holder from oscillating during the transfer of the cut piece, a staple is provided. To guarantee a good transfer, pins are preferably placed

on the blade.

  A corresponding motor is preferably placed in the area of the transfer point, to ensure the movement of the conveyor belt, so that the cut and unstacked part can be moved into the area of the product holder and conveyed to the blade for its transfer.

  A product holder of a handling facility

  The suspended material is preferably transported, by a corresponding chain, to the area of a destacking device of a sewing installation. The product holder has a clamping element in which the cut piece is suspended and then fixed. To transfer the cut piece, the product holder preferably stops at the chain return point. As a suspension counter-member during the transfer, a return pulley on which is placed is provided at the point of return.

  at the same time a clip intended to fix the holder

  products, and which comes into action, via a corresponding adjustment element, when the product holder arrives. We thus obtain that the product holder cannot be moved, for the transfer, because it can

  oscillate via the pulley of the carrier

  products. The product holder is thus positioned in the unstacking device, so as to be held directly in the area of two conveyor belts, the latter bringing the cut piece of the unstacking device to the desired position, while the conveyor belts are placed movement by a motor, and stopped, after a determined position, controlled by a sensor, has been reached. When the desired position is reached, a blade, preferably vertical, moves upward between the two conveyor belts which are spaced a defined distance apart and thus form a slit. The cut piece is thus gripped by the blade and moved towards the product holder. In doing so, the cut piece is applied around the blade and opens, with the latter, the clamping element of the product holder, moving upwards. To ensure a good transfer,

  the blade is provided with a surface which attenuates friction

  to prevent the cut piece from hanging on the product holder when the blade comes out of

  it, and is therefore not pulled out of the product holder.

  On the other hand, the blade is designed so that the clamping element of the product holder, subjected to the action of a spring, opens with certainty when the blade is inserted. In order for the cut piece to be gripped by the blade, the latter preferably comprises elements in the form of pins which prevent the cut piece from falling when the blade rises. When the cut piece has been transferred to the product holder, the blade is removed from the product holder, and retained by the element

  tightening the latter. After transfer, the holder

  products with the cut piece, moves away from the unstacking device, via the catne, so that after deposit, a new cut piece can be prepared via the conveyor belts, and that a new door -products can be routed by

through the chain.

  The cooperation of the motor of the conveyor belts

  tees and a corresponding sensor is particularly advantageous, as it can thus be guaranteed that the part

  cut always takes the same position in the holder

  products, and that the following processing stations find

  Always have defined conditions for further handling. Various other features of the invention

  emerge from the detailed description which follows. A way

  of embodiment of the invention is illustrated by way of nonlimiting example in the appended drawings to which_ Figure 1 is a schematic view of the device according to the invention;

  Figure 2 is a schematic cross-section

device tick.

  As shown in FIG. 1, the product holder 4 of a suspended handling installation is brought in,

  via a chain 1, -in the immediate area

  diate of an unstacking device 21. The chain 1 allows the product holder 4 to be brought into the desired position thanks to the correct length of chain 1,

  regardless of the height of the manual installation

  suspended suspension. For taking up the cut piece 15 from a sewing installation, the unstacking device 21 is provided with conveyor belts 6. After unstacking, the cut out piece 15 is brought into the desired position, by means of conveyor belts 6 which are driven by a motor 19. A

  corresponding detector 18, which in terms of technology

  control, is coupled to the motor 19, delivers at this point a cut-off signal from the motor 19, when the part

cut 15 is reached.

  For the transfer of the cut piece 15 in the product holder 4, it is necessary to fix the latter in the desired position, by a clip 16 which can

  preferably slide horizontally, through the

  median of an adjusting element 20, and which is connected to

  the return pulley 2 of the chain 1, by a support 17.

  Indeed, the pulley 3 would cause an oscillating movement. It is particularly advantageous to block the product holder 4 at the return point of the chain 1, since in this case, the return pulley 2 can serve as a suspension counter-member during the transfer in the vertical direction. A blade 8 is disposed directly below the product holder 4, between the conveyor belts 6 which are spaced from each other by a certain distance, and thus form a slot 7. To carry out the transfer of the cut piece 15 in the product holder 4, the cut piece 15, controlled by a detector 18, is located exactly at a certain distance above the blade 8, so that only a defined area of the cut piece 15 reaches the holder -products 4. Thanks to a corresponding drive 13 as well as to a fixing 14, a guide member 10, a suspension 11 and a housing

  12 for blade 8, it can move preferably

  reference vertically. To orient the blade 8 relative to the product holder 4, the blade 8 can be pushed into the

  housing 12. The transfer of the cut piece 15 is

  operates in that the blade 8 is moved, preferably vertically upward, by the drive 13, in that it grasps the cut piece 15 and opens, with the latter, the clamping element 5 of the holder products 4, and thus pushes the cut piece 15 into the product holder 4.

  To ensure good transfer, the side faces

  the of the blade 8 are preferably provided with a layer reducing friction, which prevents the cut piece 15 from remaining attached when the blade comes out of the

product holder 4.

  To prevent the cut piece 15 from falling when the lanie 8 rises in the product holder 4,

  pins 9 are placed on the front edge of the blade 8.

  After transferring the cut piece 15 into the product holder 4, this is moved away from the area of the unstacking device 21, by the chain 1, and at the same time

  time a new product holder 4 is prepared.
