Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preparing a bales of cotton, chemical fibers or the like in a row along, for example, a fiber baler take-out machine. The bales are mounted with a slight inclination in one direction and the other bales with a vertical or opposite inclination, in which case according to German patent application P 42 14934.7 the holding or supporting device is moved to the first bales. The holding or supporting device holds or supports the first bale and the holding or supporting device is moved away from the first bale again.

[0002]

The problem of the basic application P 42 14934.7 is to support the first bales or bales in a simple and reliable manner and to be able to automatically prepare a row of bales of fibers.

[0003]

This additional application is to provide another particularly preferred arrangement for solving the problems of the basic application.

[0004]

The movement of the holding or supporting device according to claim 1 is preferably horizontal.

[0005]

The fiber bales are usually compressed by packing the press mold a number of times and each subsequent pressing step. This gives a layered construction, which rises somewhat strongly upwards after the holding belt has been unwound. In that case, the lateral dimensions of the bales are substantially maintained, so that the lateral sides of the bales have stronger strength. The horizontal action of the holding or supporting device allows the holding or supporting device to act laterally and / or in some cases longitudinally of the bales, thereby reliably holding or supporting the bales.

In the following, the support and the holding of the bales must be distinguished, in which case the holding of the bales means that the holding device acts parallel to the feed or transfer section, and thus generally the bales. It means that the bales are generally supported on the vertical side of the bales.
Operates in the opposite direction to the transfer direction.

According to a preferred method, the holding device is arranged parallel to the first bale on the transfer section, in which case the holding is effected by exerting pressure on the side or end face of the first bale. Be seen. Preferably, the holding is done by clamping the sides of the first bale or bales. The supporting is preferably performed with the first bale in the transfer direction or vice versa. In that case, the bales are preferably transferred along holding members which extend parallel to the transfer direction.

Preferably, the displacement carriage is moved to the loading position before the transfer section, the supporting walls of the displacement carriage are pressed against the first bale, and the right and left needle plates of the holding device are released from the first bale. , The first bale is moved onto the replacement carriage with the support wall moving in the direction of the arrow, and the right and left needle plates are pressed by the bale that is pushed later. According to this configuration of the invention, individual bales can be taken out of the transfer section and moved to another position, for example to a conveyor belt, which conveyor belt is a baler, for example the Brute Blender Mart BDT 020 from Trutzler. Used for.

Preferably, before the displacement carriage is moved, its support wall is tilted beyond the vertical to a negative angle alpha when the first bale touches. Preferably the first two to six bales are delivered to the conveyor belt at a negative angle alpha. Preferably the trailing bale leans against and is supported by the bale whose upper area is laid by the negative angle alpha after the supporting wall is inclined by a positive angle alpha after reaching the conveyor belt from the displacement carriage. To be done. Preferably, the last bale brought to the conveyor belt is held by a holding device until a balance of pressing forces is obtained between the bale mounted at negative and positive angles alpha. Preferably the advance release or transfer section, the displacement carriage, the displacement belt stop and / or the movement of the support or holding device is provided by at least one sensor.

In order to carry out the method, in a device in which a fiber bales, preferably made of cotton, chemical fibers, etc., are prepared in a row, for example along a fiber baler take-out machine, the first bales of the row are on the transfer section. It is tilted slightly diagonally in one direction and the other bales are tilted vertically or slightly diagonally in the opposite direction, and the holding device is arranged so as to be movable laterally from the first bale.

[0012]

The present invention will be described in detail below with reference to the embodiments shown in the drawings. According to FIG. 1, the loading carriage 22 is located at the beginning of the transfer section 80 that moves in the direction of arrow A, and accommodates the fiber bales 1 to reach one end of the fiber bales 1 stacked on the transfer section 80. I am about to transfer. The side surface (end surface) of the first bale 1a, and thus the first bale on the transfer section 80, is held by the needle plate 85 fitted into the bale. The replacement carriage 81, which is still in the loading position in front of the transfer section 80, already contains the fiber bales 1 and is ready to be transferred on the slide rail 86 to the unloading point of the head of the conveyor belt 14. It's done.
Since the conveyor belt 14 is fully loaded with fiber bales, the holding device, ie the needle plate 85, is not engaged with the fiber bales 1 at the head of the conveyor belt 14.

FIG. 2 shows the individualized area of the bale 1. The first bale 1a is held by the needle plate 85. The support wall 88 of the replacement carriage 81 moves to and supports the first bale 1a. The throat plate 85 is pulled back. After that, the transfer section 80 steps in the same manner as the replacement belt 89 in the replacement carriage 81. The bale 1a is moved in the direction of arrow A by the support wall 88. Advancement of the transfer section 80 is stopped. The needle plate 85 is fitted into the side surface of the bale 1a '. Bales 1
a is further moved in the direction of arrow A on the replacement carriage 81 by the replacement belt 89 so that the bale 1a 'can come freely. Then, the replacement carriage 81 can be moved to the second position on the traveling rail 82, that is, the unloading position in front of the conveyor belt 14.

As is apparent from FIG. 3, there is only one bales 1 on the conveyor belt 14, that is, the conveyor belt 14 has just been loaded with new bales. This bale 1 is held in that position by the needle plate 85,
Further, as will be described later, it is inclined in a direction toward the replacement carriage 81.

FIG. 4 shows the replacement carriage 81 in the end position in front of the conveyor belt 14 on which the fiber bales 1 are fully loaded.
Since the fiber bales 1 lean against each other, holding is no longer necessary. Therefore, the needle plate 85 has been moved in the direction away from it.

FIG. 5A shows that the needle plate 85 is linked to the boom 84 operated by the pressure cylinder 93. The boom 84 is connected via a plain bearing 91 to a portal which extends over the transfer section 80 in the area of the bale 1a. FIG. 5 (b) shows another embodiment of the present invention. In this embodiment, a slide rail is provided instead of one needle plate 85 having a boom 84, and the first bale 1a is The needle plate 85 presses against the slide rail.

The individualization of the bales 1 is shown in FIGS. 6 (a) and 6 (b). A number of bales 1 on the transfer section 80 are indicated by arrow
It has been transferred in the direction and is placed at an angle. The foremost bale 1a is held in that position by the needle plate 85 acting on the end face. The replacement carriage 81 is located in front of the transfer section 80 in the stacking position. The support wall 88 is pulled out and is in contact with the side surface of the first bale 1a.
In this state, the needle plate 85 can be pulled back in order to expose the side surface of the bale 1a and hold it only by the support wall 88 of the replacement carriage 81. After pulling back the throat plate 85, the advancement of the displacement belt 89 is actuated at the same time as the advancement of the transfer section 80, whereby the transfer section is advanced by one step, ie by one bale.
As a result, the new first bale 1a ′, which is the second bale 1 thus far, comes to the end position of the transfer section 80. Throat plate 85
Is pushed laterally again. The replacement belt 89 further transfers the first bale 1a until there is a free space between the bale 1a and 1a '. Next, the inclination of the bale 1, that is, the traveling rail 8
The angle alpha of the support wall 88 is adjusted for transfer onto the upper part 2.

The placement of the bales 1 on the conveyor belt 14 is shown in FIGS. 7 (a) to 7 (c). After the displacement carriage 81 has been moved to the end position in front of the conveyor belt 14 where the bale 1 has not yet been placed, the first fiber bale is backed by the displacement belt 89 while maintaining a negative angle alpha of about 15 degrees. Supported by the wall 88 and moved onto the conveyor belt 14, the conveyor belt 14 is further moved one step, i.e. one bales width. When the support wall 88 reaches the conveyor belt 14, the conveyor belt, like the displacement belt 89, rests and the needle plate 85 of the holding device is pressed into the first fiber bales 1 indicated by the reference numeral 1b, which it positions. Hold on. Similarly, the next three to five bales 1 are placed, and in that case, the bales 1b that are always placed last are held by the needle plate 85 of the holding device. Normally, 3 to 5 bales 1 are placed at a negative angle alpha and then the replacement carriage 81
When it reaches the end position before the bale 1, the bale 1 to be supplied next impinges on the bale 1 already mounted with the conveyor belt 14 started at a positive angle alpha (FIG. 7).
(B)) After that, the support wall 88 is inclined so that the angle alpha becomes positive (always with the conveyor belt 14 moving simultaneously), and after reaching the end position, that is, the angle alpha is a positive angle of about 15 degrees. Replacement belt 8
9, the bale 1b is transferred onto the rotating conveyor belt 14. As a result, a triangular portion 90 is formed between the bales 1b ′ having a negative inclination and the bales 1b, and the triangular portion is exaggeratedly enlarged in FIG. 7 (b).
In fact, the deformation of the bale makes the upper area much smaller.

After the bales 1b occupy the position of the starting end of the conveyor belt 14, the bales 1b are fixed in that position by the needle plate 85 in the same way as the previous bales 1b '. The support wall 88 of the replacement carriage 81 can be returned to its original position and the next replacement process can be started, in which case the conveyor belt 14 finally ends in each case.
The bale 1b placed on it is held by the needle plate 85 until pressure equilibrium is obtained between the positive angle alpha and the negative angle alpha.

The replacement process is carried out by clamping the last-supplied bales with positive slope in each case with the needle plate 85, until a pressure equilibrium occurs, and thus with bales 1 and positive slopes with the same number of negative slopes. Bale with conveyor belt 14
Repeated until placed on top. By that, bales 1
Can stand upright and need not be clamped by the needle plate 85.

The conveyor belt 14 is provided with a working area between the positions I and II where the bales 1 are processed, and the working area is followed by a first storage area between the positions II and III. There is. A second storage area is provided on the transfer section 80 between positions IV and V. Arrows A and C indicate transfer section 80
The direction of movement of the conveyor belt 14 is indicated by arrow B.
Indicates the movement of the replacement carriage 81, arrows D to F indicate the movement of the needle plate 85, and H and I indicate the movement of the support wall 88 when the bale 1 is inclined.

FIG. 8 shows that the bale transfer carriage 22 and the bale 1n 'on it are moved above the transfer section 80 until they come into contact with the last bale 1n placed on the transfer section 80. . The bale transfer carriage 22 is the marking device 1
No. 02 is mounted, and the marking device has a marking 105 on its end face at a predetermined distance from the front edge of the bale 1n ′.
To provide. The fiber bales 1n 'are always aligned in the same position on the bales transport carriage 22, i.e. edge 1
Since it is in contact with 07, the marking 105 is always provided at the same position regardless of the width of the bale.

The marking can be formed as any marking. For example, it can be in the shape of a medal fixed in the bale 1n 'by a needle. However, it preferably consists of color spots of high-contrast color applied via the spray device, i.e. in this case the marking device is a spray device.

The direction changing roller 10 behind the transfer section 80
The sensor 101 is arranged in the area of 6. When the marking 105 reaches the sensor 101, a signal is generated which activates a different switching process. When the marking 105 reaches the sensor 101, the bale 1a 'reaches the end position on the transfer section 80. The signal thus generated stops the advancement of the transfer section 80. Bales 1 at the same time
a'is fixed in that position, ie, as described above,
The end face side can be tightened. The previous bale 1a, which is in contact with the support wall 88 and which is moved via the displacement belt 89 with the support wall, has been moved to a substantially vertical position by the change in the support angle, whereby the first bale. A gap 103 is formed in the lower region between 1a and 1a '. The displacement belt 89 then moves with the support wall 88 to the end position, so that the first bale 1a is free and therefore no longer contacts the first bale 1a '.

FIG. 9 shows an alternative to FIG. 8 that does not require marking. In this structure, the detection roller 104 is arranged in the area between the transfer section 80 and the replacement belt 89, and the detection roller 104 is the first bale 1a.
Slides along the bottom surface of the first bale 1a when being transferred onto the replacement belt 89 of the replacement carriage 81.
When the load on the detection roller 104 is removed by the gap 103 between the first bale 1a and the first bale 1a ', a signal is generated which stops the transfer section 80 as described above and the first bale 1a'. Is used to lock in place.

An alternative to this structure is shown in FIG. Gap 10 in the base area of the bales that touch each other
Since 3 can be very small, at least theoretically, the detection roller 104 may not detect the gap 103. However, if the belt above the replacement belt 89 is located lower than the belt above the transfer section 80, the first bale is the support wall 88 and the first bale to be pushed from behind when the first bale 1a is handed over. 1
Guided by a ', it slips a predetermined distance onto the displacement belt 89, which produces a paragraph here that can be reliably detected by the detection roller 104 and generate a signal.

FIG. 11 shows another mechanical method for detecting the gap. In the present embodiment, an insertion station 109 is provided on the bale transfer carriage 22, and the insertion station 109 is provided on the end face side of the marker thin plate 108, preferably the bale 1n 'when the bale 1n' arrives at the bale 1n. The bent marker thin plate 108 is inserted. The marker thin plate 108 is held at that position by pressing the bale 1n ′ onto the bale 1n. A take-off and detection station arranged in the area of the diverting roller 106 of the transfer section 80 inductively detects this sheet and removes it,
In the meantime, a gap 103 is formed between the bales 1a 'and 1a.

FIG. 12 shows an embodiment used instead of FIG. However, in this embodiment, instead of the marker lamina 108, a wedge 111 is placed on the transfer section 80 by the insertion station 109 and pressed against the bales 1n by the bales 1n ', thereby forming a separation area between the individual bales. It In this case, if the wedge is a metal wedge, the ejection and detection station 110 operates inductively. However, the detection can also be configured based on ultrasound or as a reflective photointerrupter.
