Abstract

In the tube loader there is means to split the tapered tubes (18, 19). The pipe has a larger diameter at one end and a smaller diameter at the other end. There are also means for aligning the tubes (18, 19) in the correct position, means for erecting the tubes (26, 28), means for transferring the tubes to receiving means. Connect the tube transfer unit (50) to the receiver unit. There is at least a separating device (20) or a receiving device (40) as one part, which is supported on a pivot axis or slides along guides (71, 72, 12b, 12d). The result is a compact pipe loader for reliable transfer of pipes (18, 19) from the receiving device (40) to the pipe transfer device (50). In addition, there is a sliding head (30) for pinning the position of the end of the pipe and orienting the pipe, and there are carriers (31a, 31b) on the sliding head, as well as a guide plate (26) and a funnel (28) for erecting the pipe. Through the reciprocating movement of the sliding head (30), the tube (18d) always falls into the funnel (28) with the end having the smaller diameter first. Thus, all tubes leaving the funnel (28) fall on the tube conveyor in the same orientation.

Description

Pipe loader and textile machine equipped with such a pipe loader

The invention relates to a pipe loader with a device for separating pipes, from which the pipes are transferred to a receiving device, to which the pipe transfer device is connected.

This type of tube loader can be installed on textile machines in order to supply new tubes. According to the tube loader described in the patent document US-PS2908248 (CH-PS569807), the tubes are in each case arranged parallel to each other in the same direction. It follows that, with a large number of pipes in the vessel, the position occupied by the highest pipes is highly inclined. A position that is too inclined will result in the individual tubes being in a lateral position so that the conveyor cannot grip the tubes. It can also happen that the individual pipes are not in the correct position in the container, at which point it is only easy to transport the pipes, rendering the simple handling mechanism useless.

There are also tube loaders with conveying means which in each case arrange the tubes in defined positions, that is to say bring the tubes into defined positions and then bring the tubes under the same conditions to the subsequent conveying element. During the further transport of the tubes, the tubes are pinned down and organized, so that such a device takes up a considerable amount of space.

From patent application document 0464885 it is known that a tube loader has means for separating the tubes, which means is a belt conveyor. There are several fixed carriers on the conveyor belt, which convey the pipes upwards and then drop them into the hopper. Through the connected pipe, the fitting goes to where another conveyor is located. The conveyor runs in a horizontal direction and can receive large quantities of pipes. The push-in mechanism then passes the tube through to the tube conveyor. In practice, these known tube loaders occupy a considerable amount of space, so that a large number of tubes are always accumulated in the production system.

In German patent specification DE-3336958, a tube loader is described with a receiving device arranged as two half housings. To transfer the tubes from the receiving device to the tube delivery device, the two housing halves are pivoted laterally to the delivery device. The pipe must therefore reach the receiving journal in the delivery device reliably, which requires that the lateral pivoting of the housing half be adjusted with precise timing when the journal passes under the receiving device. It cannot be guaranteed that there will not be another defective conveying device in the receiving device.

The object of the present invention is to provide a receiving device which is able to ensure the delivery of the tubes from the receiving device to the tube transfer device. According to the invention, the inventive task of supporting the receiving device to slide along guides parallel to the tube conveying device is achieved. During the sliding of the receiving device, the tube is transferred to the delivery device. Subsequently, when the receiving device runs over the receiving journal in the pipe conveying device which is running synchronously with it, the pipe can be accurately conveyed onto the journal of the conveying device.

The object of the present invention is to provide a compact tube loader. This inventive task is achieved according to the invention in that the supported receiving device slides along guides parallel to the tube feed device.

The means for pinning down the ends of the tubes and for aligning the tubes consist of sliding means. The means for correct orientation of the pipe consists of the receiving means. The sliding device slides relative to the pipes through the receiving device, and after the sliding operation, only one certain end of each pipe is supported, while the other end first falls into the receiving device. The pipes are then guided onto a pipe delivery device, for example, a slide consisting of a slide head with a carrier. After the movement of the sliding head, only one end of the pipe is supported, and the pipe moves under the action of the guide until it falls into the funnel.

In order to separate the pipe fittings, a funnel with a roller is provided below the pipe fitting storage device, and there are two grooves on the circumference of the roller, which can respectively hold a pipe fitting and rotate with the roller. After turning a certain distance around the circumference of the drum, guides are used to guide the pipe away from the peripheral surface of the drum so that the pipe enters a pinning position above the funnel. A slide head with a carrier is provided parallel to the single pipe at the pinning position of the pipe. The sliding head reciprocates longitudinally along the pipe. During the forward or return strokes of the sliding heads of the configured carriers, one of the carriers can grip the end of the pipe having the larger diameter and slide the pipe. The erected pipe then exits the funnel to the receiving device of the pipe feeder and is conveyed on by the pipe feeder. For example, the pipe conveying device may be a drum, and there may be a chute on the peripheral surface of the drum, and the drum may be driven in a stepwise manner as the separating device operates. The drum is positioned above the pipe conveyor and is driven in coordination with the pipe conveyor. Thus in each case a single chute can reach above the tube conveyor, through which the tubes can slide on the edge of the floor, traveling a distance with the drum. Finally make the fitting drop on the journal each time. The advantage is that when the guide plate is arranged obliquely above the drum along the running direction of the pipe conveying device, the pipes that have been in the chute are pushed down onto the journal during the continued movement of the drum or pipe conveying device, In this case, the tube is guided downwards by the guide plate in the region of the end of the tube with the smaller diameter. The drum is driven by a wheel, which cooperates with the pipe conveying device by means of grooves on the outer circumference of the wheel. The grooves of the wheels engage the tensioning conveyor by means of carriers or journals on the tensioning conveyor.

The device according to the invention requires few moving parts and is characterized by a simple structure. Desirably, the device can handle tubes in a defined position or in an out-of-sequence arrangement, and the device is easily compatible with different types of tube transfer devices.

The present invention is described in detail below by means of the accompanying drawings.

Figures 5a, 5b, 5c, 5d are another embodiment of the tube loader.

A number of tubes are placed in a container 16 having a bottom opening 16a, which tubes pass through a funnel 14 to a drum 20 . The tubes are placed in the container 16 with their longitudinal axes parallel to each other and perpendicular to the plane of the drawing. The pipes are positioned in the container in a non-oriented manner, i.e. either the pipe ends 18a, 18b, 18c with the smaller diameter, or the pipe ends 19a, 19b with the largest diameter pointing towards the viewer, when the pipes in the pipe loader 10 are oriented The pipe loader 10 can be used effectively, either correctly or incorrectly, as this can happen. Because, as shown in FIG. 2, the tube is guided laterally over a short path into the groove 22a by the shoulders 25a, 25b of the grooves 24a, 24b. By means of the carriers 31a, 31b on the slide head 30, the pipe 18d located in FIGS. 1a and 2 can be slid. As shown in FIG. 1 a , the arm 34 may pass completely through the slider 30 and protrude from the other side, thereby forming a guide for the slider 30 within the guide tube 33 . The arm 34 is held in a circumferential position within the guide tube 33 through the slide head 30 . The slide head 30 can only slide longitudinally in the long holes 33a, 33b.

On the peripheral surface of the drum 20, the tubes 18, 19 are separated so that they fall into the grooves 22a, 22b, 22c, and the tubes are removed from the funnel 14 by rotating the rolling drum in the direction indicated by the arrow 22c. As soon as the tubes 18, 19 reach the circumferential surface of the drum 20 above the guide 26, as shown in Figure 2, the guide 26 stretches into the groove 24a, and the tubes 18, 19 are lifted out of the groove 22a, as shown in Figure 1a The pipe is shown in position 18d. As shown in FIG. 2, the drum has two grooves 24a, 24b into which two guide members 26 respectively protrude, so that the guide members 26 support both ends of the pipe members 18, 19. As shown in FIG.

As shown in Fig. 1a and Fig. 2, when the pipe is at the position 18d, the position of the pipe is controlled by the sliding head 30. The sliding head inserted into the guide pipe 33 is reciprocated by means of the cam curve 23 on the front side of the drum 20 . The movement produced according to the double arrow 33 in FIG. 2 is transmitted from the cam line 23 to the sliding head 30 via the roller 35 and the arm 34 . A spring 32 located between the slide head 30 and the housing 39 of the pipe loader 10 presses the roller 35 against the contour of the cam curve 23 so that the slide head 30 follows the trajectory of the cam curve 23 . Each time the tube reaches the position 18d shown in Figures 1a and 2, the sliding head performs a reciprocating movement. Through reciprocating motion, the carriers 31a, 31b run in the direction of the left end or the right end of the pipe, as shown in FIG. 2 . As can be seen in Fig. 1a, the lower edge 31c of the carrier 31b protrudes downwards so as to be able to grip the end of the pipe with the larger diameter, but cannot contact the end of the pipe with the smaller diameter as shown in Fig. 1b. The function of the carrier 31a is the same as that of the carrier 31b described above. After that, the pipe 18d is slid by the reciprocating motion of the sliding head 30, and this sliding causes the end of the pipe with the largest diameter D to be pushed past the edge 26c each time, as shown in FIG. One end is no longer supported, and this fact causes the pipe to oscillate in the funnel 28 because the pipe has a smaller diameter d. This end remains supported as before on the left-hand guide 26, keeping this end of the pipe at a higher position. high position. The pipe 18d can be displaced laterally during the further conveyance by means of the rollers 30 by means of two fixed guide elements 82 and 84 which are arranged near the outer contour of the rollers and which can replace the slide head 30 . This arrangement allows the pipe with the larger diameter end to slide along its axis.

In this way, the tube shown in FIG. 1f reaches the position at one end of the funnel 28 indicated by the dotted line. As the pipe falls into the funnel, it stands upright as it rests on the left guide 26 . The pipes 18d falling into the funnel 28, in a more or less upright position, then, as shown in FIG. As shown in FIG. 3 , the shroud 44 covers approximately one-third of the circumference of the drum 40 . The pipes 17c are shown in their position during descent, while the pipes pre-entering the chute 42b are at the lowest position around the drum 40, supported on the bottom plate 46. As shown in FIG. 3 , the bottom plate 46 extends in the direction of the pipe delivery device 50 , so that the pipes 17 b , 17 c are supported from the bottom until each time the position of the journal 52 b of the pipe delivery device B is reached. Once the tube 17a is no longer supported by the base plate 46, the tube drops onto the journal 52b below the base plate. The drum 40 is run with the pipe delivery device 50 in order to ensure that each pipe 17a is aligned with the proper journal 52b. Through the embodiments described below, the above operation process can be realized by means of mechanical transmission or circuit connection. For the mechanical transmission, in the simplest case, the drum 40 is coaxially connected with the wheel 49 by means of the shaft 48, so that the driving wheel 49 and the coaxial drum 40 make the parts of the pipe delivery device 50 snap into the wheel. 49 in the grooves 49a, 49b. In FIG. 4, the carrier is fixed on a tensioned conveyor 58a which is driven in the longitudinal direction so that the sliding journal 52 moves forward. Carrier 56 drives wheel 49 in a geared manner so as to rotate drum 40 and wheel 49 in a clockwise direction as indicated by arrow 49c. As shown in FIG. 1 b , the journal 52 b slides on the track 54 a, and the neck 52 a of the sliding journal 52 is clamped by the carrier 56 . The wheel 49 can also be driven directly by the neck 52a of the journal 52b, which is fixed directly on the tensioned transmission member 58b. The tensioned conveyor may be supported by the frame 54c or the rotary drive mechanism of the pipe delivery device. In Fig. 1 e, the parts of pipe conveying device 50 are shown, rail 54a, the sliding journal with neck 52a that slides on the rail, journal 52b, and the transmission member 58 of tension, be fixed on by neck 52a Tensioning the carrier 56 on the conveyor 58a moves the slide journal 52 forward.

In order for the tubes 18d to fall into the funnel with accurate timing, the movement of the drum 40 and roller 20 must be coordinated as the tubes are pushed by the slide head 30 and are no longer supported by the side guides. In order to synchronize the movement of the drum 40 and the drum 20, a simple circuit as shown in FIG. 4 can be provided. Sensing elements 62 at the periphery of the wheel 49 act as synchronization means for the controller 60 . For each pulse, the drum 20 must be rotated one more step, that is, the angle between the two grooves 22a and 22b is rotated so that all the chute 42a, 42b on the drum 40 are fitted with pipes, and then, A pipe arrives on each journal 52 of the pipe delivery device 50 . The drum 20 is driven by the motor 11 and the transmission member 11a, so that the drum rotates at a constant speed, and the number of pipes taken out from the funnel per unit time is equal to the number received on the pipe conveying device. The tension transmission parts 58a, 58b of the pipe conveying device 50 move at a constant speed, and the motor 11 theoretically rotates at a constant speed. Since it is not easy to maintain exactly the same speed in a control system with only electrical connections, it is possible to allow the motor to run faster so that the frequency of receiving the tube 19d is slightly higher than the frequency at which the tube delivery device receives a new tube 17a in each case. Receive frequency, as shown in Figure 3. In this case, the motor must often have short pauses so that the phase difference between the working cycles of the drum 40 and the drum 20 is not too great. The use of the second sensing element 64 can ensure that the above requirements are met. As shown in FIG. 2 , the second sensing element 64 scans the cam curve, so that the time interval between the arrival signal of the sensing element 62 and the arrival signal of the second sensing element 64 is compared with a predetermined time interval in the controller 60 compared to normal values. As soon as this interval exceeds the normal value, the motor 11 is briefly stopped so that the phase difference generated between the drum 40 and the cylinder 20 is changed so that the measured time interval reaches the normal value again. To precisely set the moment at which the pipe 18b falls into the funnel 28 so that the position of the drum 40 is time-coordinated with the position of the pipe in the chute 42a, the funnel 28, the cam curve 23 can be adjustably secured to the drum rim , so that the pipe 18d slides at the correct moment.

In order to monitor the delivery of the tubes by the tube delivery device, a simple device can be provided according to FIG. 1c. The guide piece 44a arranged according to Fig. 1c and Fig. 3 is near the top of the pipe fitting 17a, and the pipe fitting 17a pushed onto the journal 52b can enter the range where the guide piece is located, and as the drum 40 rotates, control according to Fig. 1c The tube located in the chute 42b of the drum 40 is pressed down on the journal 52a by command of the device 60. For example, if the helical spring hangs between the inner side of the largest diameter end of the pipe and the journal 52b, and cannot push the pipe 17a without additional pressure, if the pressure is relatively high, the member under the force of the spring 44b moves downward, When the ultimate pressure is reached, the guide vanes 44a are deflected aside. The spring 44b presses the guide piece 44a into the normal active position, and the stopper 44c leans against the housing 12 at this time. The third sensing element 66 can be used to indicate the swing of the guide plate 44a, and the third sensing element 66 is connected to the controller 60 through the signal wire 60d, and the connection mode of other sensing elements is the same. The signal at the third sensing element 66 signals an error to the controller 60 . The controller 60 may be connected to another controller 61, such as a pipe delivery device or a rotary mechanism, which generates a signal to stop the pipe delivery device. When the pipe 17 in FIG. 3 is instructed to transmit a position error, it must be artificial adjustment.

FIGS. 5 a , 5 b , 5 c show another embodiment of a pipe loader 10 in which a pipe conveying device 50 is provided in the lower region. As shown in Fig. 1 b and Fig. 3, replace drum 40 with cover 44, in the embodiment shown in Fig. 5 a, 5b, 5c, have fixed cover 44, it is the cavity that can form accommodating pipe part 17 with folding arm 45, This replaces the drum 40 provided with the cover 44 . The folding arm 35 is hingedly connected to the support member 44e of the cover 44 through a hinge bearing 45a. The pipe 17 stands on the bottom plate 46 . The cover 44 and the folding arm 45 are clamped to each other under the action of the spring 45b, and are in the closed position. The cover 44 is connected to the two rods 71 , 72 via support members. As shown in Fig. 5c, as a component, two rods 71, 72 are connected in parallel by a cross bar 73, and one rod is located above the other. The above-mentioned components are jointly slidable along the longitudinal direction of the rods 71, 72, and are assisted by the pipe delivery means, as described below. The rods 71, 72 are guided by means of rollers 12b, 12d. The rollers 12b, 12d are permanently hinged to the housing 12 . One end of the spring 74 is hung on the journal 75, and the other end is hung on the journal 76 of the housing. The tensioned springs hold the rods 71, 72 and the cover 44 in the rest position, as shown in Figure 5b. The stop 73 a is thus arranged on the crossbar 73 and bears against the housing 12 in the vicinity of the journal 76 .

As mentioned above, the pipe delivery device 50 mainly consists of the tension transfer member 58a shown in FIG. 5c, which supports the carrier 56 so that the journal 52 slides. This sliding journal 52 can slide on the housing 12 in a direction determined by the carrier 56 . One end of the carrier 56 faces away from the tensioned conveyor 58a, and support pins 56a are provided on the carrier. The support pin 56a supports the swing link 80 . For transporting the pipe 17 , a swing rod 80 is provided which can slide together with the rods 71 , 72 and the cover 44 . The swing link 80 can realize a rotary movement on the hinge bearing 78 relative to the rod 71 . The spring 77 presses the rocker against the cover 44 into a position where the support pin can slide to the end of the rocker 80 and the rocker 80 swings relative to the tube 17 of the mask 44 . The direction of the sliding movement is in the direction of arrow 81 in Fig. 5b. As shown in Figure 5a, along with the movement of the cover 44 and the pipe 17, the sliding shaft 52 enters the position below the pipe 17, and as long as the pipe reaches the extreme position on the left side of the bottom plate 46, the pipe falls down on the sliding journal 52. The left positions of the cover 44 and the pipe 17 are indicated by dotted lines. At this time, the position of the swing rod 80 is close to the edge of the housing 12 and is in an inclined state. During the inclination process of the swing link 80 , the swing link 80 releases the support pin 56 a, and the support pin 56 a further moves in the direction indicated by the arrow 81 . The guide plate 44a shown in FIG. 5a is pressed downward by the action of the spring 44b, and when the tube 17 falls on the sliding journal 52, the guide plate 44a urges the tube to move downward. After the pipe 17 falls on the sliding journal 52 , since the journal cooperates with the carrier 56 , the pipe 17 will move further under the drive of the sliding journal 52 . As shown by the dotted line in Figure 5b, once the support pin 56a passes over the swing rod 80, the cover 44, the support member 44e and the rods 71, 72 will return to their original positions under the action of the spring 74 shown in Figure 5b. When the tube is forcibly moved to the left position by the sliding journal 52 , the hinged arm 45 must be turned in a clockwise direction so that the tube 17 leaves the area between the hinged arm 45 and the cover 44 . Another tube will drop onto the floor 46 when the cover 44 is returned to its original position again. Another embodiment of the movable cover 44 is shown in FIG. 5d. The cover is suspended from two leaf springs 86 and 88, the ends of which are connected to the housing 12 to allow the leaf springs to oscillate. The position indicated by the dotted line 44' of the cover is the second position from which the cover can spring back to its original position. The ends 86" and 88" act as stops for the tube 17 which release the tube 17 when the leaf springs 86 and 88 are turned outwardly. The synchronous operation process of the pipe conveying device 50 and the pipe conveying mechanism has been described above. The drum moves further to release another pipe, which first passes the sensing element 60f, which senses the operating frequency of the pipe conveying device, thereby determining the course of the sliding journal 52.

For conveying the tubes 17, 18, 19 from the funnel to the guide 26, reciprocating means can be provided, similar to the hooded support member 44e, which can replace the roller 20, as described above.

The tube loader according to the invention is so compact that it can be mounted directly on a textile machine, for example as an auxiliary mechanism. If the tube loader fails, the unit can be quickly removed and replaced by another unit.
