Definitions

  • the present invention relates to a device and a method for cutting and forward-feeding a web-shaped material, to a subsequent treatment step.
  • the invention has been developed mainly with the objective of being used within the sewing field, in connection with automatic and continuous seaming of bed sheets from a web-shaped material on a supply reel e.g., but may also be used for cutting and forward-feeding of other web-shaped materials, as for example paper or paperboard materials.
  • a first, cut piece of material In a conventional cutting station, a first, cut piece of material must in this case be fed out from the cutting station in a direction towards the subsequent treatment step, before new, web-shaped material can be pulled out and cut to a second piece of material in the cutting station. Thereby, spaces will occur between the individual pieces of material as they reach the subsequent treatment step, which lowers the capacity of the entire plant.
  • US 5,133,273 has presented a solution for a similar problem.
  • a first piece of fabric is cut in a cutting station. It is thereafter fed out fast, its front part being led into a seaming machine at a slower pace, while its rear part is accumulated, i.e. falls down into an underlying space, an accumulation station. In this way, there is no need to wait for the entire first piece to slowly be fed into the seaming machine, but the cutting of a second piece of fabric can continue swiftly.
  • US 5,476,053 too, the same principle is employed.
  • the disadvantage of such a method is that the grip of and thereby the control over the longitudinal, cut edges is lost as the pieces of fabric are accumulated while waiting to be led into the seaming machine. This may lead to serious mistakes in the seaming.
  • the solution moreover requires that the seaming machine operates more slowly than the cutting and feeding-forward machine.
  • CH-A-660 719 discloses an apparatus for conveying pieces of web from a cutting machine.
  • a main objective of the present invention is to provide a device that enables a second piece of material to be pulled out for cutting, at the same time as a first cut piece of material is fed forward from the cutting station towards a subsequent treatment step, i.e. without having to wait for the first piece to be fed completely out of the way. It is also an objective that this should be able to be performed continuously at constantly retained control over the cut edges of the pieces of material. It is furthermore an objective that the cut pieces of material should be fed forward to the subsequent treatment step at a high pace and essentially without any spaces them between, so that continuous seaming e.g. may take place in the subsequent treatment step, when the material is a fabric.
  • the solution to the present problems is based on the device, i.e. the cutting station, exhibiting two "storeys", whereby a second piece of material is pulled out in a first direction in the second storey (a second vertical level) for cutting, at the same time as a first piece of fabric is fed forward in a second direction from the first storey (a first vertical level), and so on.
  • this means may be constituted by a tiltable feeder that ensures that the pieces of material end up in the same vertical level on the feeding path, towards the subsequent treatment step.
  • the third vertical level coincides with either the first or the second vertical level.
  • a bed sheet machine is illustrated in Fig. 1, i.e. a machine for the cutting of a web-shaped material in the form of bed sheet fabric 1 from a supply reel 2, forward-feeding and subsequent treatment in the form of a seaming machine 3.
  • the machine comprises a device according to the invention, i.e. a cutting and feeding forward station, that is arranged in the upper left corner of Fig. 1, generally denoted 10 and shown in greater detail in Fig. 2 and 3.
  • the device 10 comprises at least one puller 12 arranged to pull out the fabric material 1 in a first direction A, from the supply reel 2.
  • a cutting device 26 (shown in greater detail in Fig. 4 and indicated in Fig. 3) is arranged to cut the web-shaped material 1 into individual pieces of material 16.
  • the device further comprises two pairs of forward-feeding means 18a, 18b; 20a, 20b, arranged to feed forward the cut pieces of material 16 in a second direction B.
  • These two pairs of forward-feeding means 18a, 18b and 20a, 20b, respectively, are arranged at a first and a second vertical level, respectively, i.e. in two different "storeys".
  • the forward-feeding means are constituted by endless belts, each pair of forward-feeding means 18a, 18b and 20a, 20b, respectively comprising two endless belts in a first horizontal position (at 18a and 20a) and two endless belts in a second horizontal position (at 18b and 20b), as seen in said first direction A.
  • endless belts are arranged above of each other in the respective vertical and horizontal positions and are arranged to be vertically separated from each other for passage them between by the puller 12, and to be vertically brought together for clamping of the edge of the material 1.
  • the piece of material 16 can be fed on in the first vertical level in the second direction B by the endless belts being driven on rolls.
  • this may take place in the first vertical level at the same time as the two endless belts in the one part, 20a e.g., of the second one of the pairs of forward-feeding means in the second vertical level are vertically separated from each other so that the puller 12 can be led in them between to fetch a new free edge of the web-shaped piece of fabric 16, in order then to pull the fabric out a certain given distance to the two endless belts in the second part 20b of the same pair of forward-feeding means, which endless belts also are separated vertically from each other so that the puller 12 may be led in them between to deliver the fabric edge for clamping of the same.
  • the web-shaped material is cut in the first horizontal position, at 20a, to form a second piece of material.
  • the device further comprises controlling means 4 that brings the device to operate so that the first piece of material 16 just has left the first pair of forward-feeding means 18a, 18b when the second piece of material just has been cut off from the web-shaped material 1. Accordingly, the second piece of material can be fed on in the second vertical level in the direction B, by the endless belts in the forward-feeding means 20a, 20b, in the same way as took place with the first piece of material in the forward-feeding means 18a, 18b, at the same time as a pulling-out and cutting cycle is commenced anew in the first vertical level.
  • said first direction A and said second direction B are perpendicular to each other in the horizontal plane.
  • the device preferably comprises two pullers 12, i.e. one for each vertical level, only one puller however being showed.
  • the device suitably also comprises a holder clamp 28, which comprises an upper holder ledge 28a and a lower holder ledge 28b, that together are arranged to grip the web-shaped material 1 and that both preferably have a dented front edge, which also the pullers 12 have (not shown), in such a way that the dented edge of the respective puller 12 may engage with the dented edge of the holder clamp in order to ensure transferring of a free, cut edge of the web-shaped material 1.
  • the holder clamp 28 also comprises means 30, preferably in the form of hydraulic or pneumatic cylinders, in order to alternately position the free, cut edge of the web-shaped material 1 in the first vertical position at 18a and at the second vertical position at 20a, respectively.
  • the cutting device 26 is preferably arranged to operate between the holder clamp 28 and said endless belt in this first horizontal position, at 18a and 20a. Thereby, the web-shaped material is held in place by the holder clamp and the endless belts, with a small space them between, so that the cutting device 26, in the form of a cutting blade e.g., may operate in this space.
  • the holder clamp 28 transfers the material to the next vertical level, by aid of the means 30.
  • the puller 12 is to pull out a new piece of material, the holder clamp lets go of its grip of the material, in order then to grip it again when the cutting is to take place.
  • the forward-feeding means 18b, 20b in the second horizontal position are arranged to be displaceable in horizontal direction in the first direction A, in order to achieve a variable setting of the width of the pieces of material that are to be cut off. In continuous operation, they are however in the same horizontal position all the time, as long as the pieces of material are only manufactured in one single width. It is however also conceivable, in another embodiment of the invention, that these forward-feeding means 18b, 20b also have the function of the puller, in which case they run forward and back in the first direction A during continuous operation of the device.
  • the device In order to transfer the individual pieces of material to the subsequent treatment step, here exemplified by a seaming machine 3, in one and the same vertical level, the device also comprises means 22 to alternately from the first and the second vertical level feed forward the cut pieces of material in the second direction B in a third vertical level, to this subsequent treatment step.
  • this means 22 for alternating feeding comprises a pair of tiltable feeders 22a, 22b, that are arranged to alternately receive pieces of material in said first and second vertical level, respectively, and to feed them forward in the third vertical level, to the subsequent treatment step 3.
  • Fig. 2 shows the tiltable feeders 22a, 22b, when they are in a lowermost receiving position, i.e.
  • Fig. 3 shows the tiltable feeders 22a, 22b, when they are in an uppermost receiving position, i.e. when they fetch a second piece of material (which is however not shown) from the uppermost pair of forward-feeding means 20a, 20b.
  • the tiltable feeders 22a, 22b preferably comprise two endless belts that are arranged to grip the cut edges of the pieces of material. The same is done by a subsequent feeder 24, arranged to feed on the pieces of material in the third vertical level, to the treatment step 3.
  • the invention is not limited by the embodiment described, but may be varied within the scope of the Claims. It is to be realised e.g. that the device may comprise more than two different vertical "storeys". It is also to be realised that a double web-shaped material may be pulled out, suitably from two different supply reels, for cutting and feeding forward of fabric pieces for the seaming of quilt cover bags e.g.
