Description

FIELD OF THE INVENTION This invention relates to the processing of sheet material, and more particularly, to installations for the longitudinal cutting of chipboard or fiberboard.

The purpose of the invention is to increase productivity by feeding and orienting a sheet from a single drive.

Fig. 1 shows a general arrangement for cutting a sheet; Fig. 2 is a movable guide bar with a linkage mechanism; in Fig.3 - view A in Fig.1, i.e. top view of the feed roller table; in Fig.4 - view B in Fig. 1, i.e. bottom view of the feed roller table.

The installation consists of a feed roller 1, a cutting device 2 and a receiving roller 3.

The feed roller 1 comprises a housing 4 and rollers 5. On the feeding roller 1, a sheet feeding unit 6 and an orientation unit 7 of the sheet are mounted. The feed unit 6 of the sheet is made in the form of a drive frame mounted with the possibility of reciprocating movement on the housing 4 of the roller table 1. and contains guide rods 8.9, rear stops 10 and a pneumatic drive 11. Guide rods 8, 9 of the sheet feed unit 6 installed in the guide sleeves 12. The pneumatic actuator 11 and the guide sleeves 12 are rigidly fixed to the roller table body 4. The orientation unit 7 of the sheet is made in the form of a fixed ruler 13, a movable ruler 14 and a linkage mechanism. The fixed bar 13 is attached to the housing 4 of the roller table 1 and is spring loaded. The movable bar 14 is provided with guide pins 15 located in the guide bushes 16. The guide bushes 16 are rigidly mounted on the housing 4 of the roller table 1. The linkage mechanism consists of a link 17 with a groove

18. the connecting rod 19 and the roller 20. The link 17 is hingedly connected at one end to the housing 4 of the rolling table 1, and at the other end to the connecting rod

19. The connecting rod 19, in turn, is articulated

dinene with the middle part of the movable ruler 14. The roller 20 is mounted on the end of the guide rod 9 and is located in the groove 18 of the link 17. The cutting device 2 consists of a frame 21, two lower drive rollers 22, two upper pressure rollers 23 and a cutting head 24 with disk knives 25. The receiving roller 3 includes a housing 26, rollers 27 and an actuator 28 for rotating the rollers 27.

Installation for cutting sheet works as follows.

The sheet by the reloading device is mounted on the feed roller 1 and the pneumatic drive 11 of the sheet moving unit is turned on. Under the influence of the pneumatic actuator 11, the rear stops 10 and the roller 20 will begin to move along the roller table 1. The stops along the roller table 1 of the stops 10 and the roller 20 are provided by guide rods 9 moving in the guide sleeves 12. The moving roller 20 rolls along the groove 18 of the wings 17. rotates it. The drawstring 17, at the moment of rotation, moves the connecting rod 19 with the ruler 14 across the live roll 1. The ruler 14 is moved across the live roll 1 with guide pins 15 and bushings 16. The stops 10 and the ruler 14 act on the sheet simultaneously at the moment of movement. The moving ruler 14 presses the sheet: the fixed spring-loaded strip 13, thereby providing orientation and fixation of the sheet. The moving stop 10 moves the sheet onto the first drive roller 22 of the cutting device 2. After feeding the sheet to the drive roller 22, a limit switch (not shown) is activated and the first pressure roller 23 is lowered.

Then, the rotation of the feed roller 22 and circular knives 25 is automatically activated. The sheet, under the influence of the driving roller 22, will begin to move between the circular knives 25. At the moment the sheet

move to the second drive roller 22, the second pinch roller 23 is lowered, and the first pinch roller 23 rises. Cut along the sheet from the cutting device 2 will go to the receiving roller 3. From the receiving roller 3, the cut sheet is sent for further processing. Fore M.ul a. of the invention - 1. Installation for cutting a sheet, comprising a cutting device, feeding a roller conveyor with sheet feeding and orientation units, a receiving device and a back stop, characterized in that, in order to increase productivity, the sheet feeding unit is designed as a drive unit frames with guide rods mounted on the housing of the feed roller table with the possibility of reciprocating movement along

negro, and the sheet orientation unit is made in the form of a drive rocker mechanism pivotally mounted on the housing of the feed roller, two guide rulers located in the plane of the guide rods, one of which is rigidly mounted on the housing of the feed roller and is spring-loaded relative to it, and the other mounted parallel to it and mounted on the rocker-link mechanism through one of. guide rods with the possibility of movement relative to the roller table, while the rear stop is fixed at the ends of the guide rods.

2. Installation according to claim 1, on the basis of the fact that the rocker-lever mechanism is made in the form of a rocker with a groove mounted with the possibility of swinging, one end of which is pivotally connected to the housing

feed roller table, and the other with the middle part of the movable ruler by means of a connecting rod. and a roller mounted on the end of the guide rod mounted on the side of the movable ruler, with the ability to move along the specified groove.
