    For feeding logs to a sawing machine, two parallel horizontal I-beams, at a level above the sawing machine, guidingly support an inner and an outer feed carriage. From each carriage pincers-like log supporting jaws extend obliquely downwardly and in the feed direction. The I-beams provide an inner track that has its rails between the rails of an outer track. The inner carriage is wholly between the rails of the inner track and rides thereon. The outer carriage bridges over both tracks and rides on the outer one, and its jaw operating mechanism has portions above the level of the inner track and other portions extending down from said level that are laterally outside the outer track. The carriages can therefore pass one another and exchange leading/trailing relationship for each successive log. Mechanism is disclosed for causing carriage jaws to close on a positioned log without shifting it but by which the closed jaws can be laterally shifted as desired.

    The invention relates to the timber and woodworking industries and can be used in feed mechanisms for sawing logs.
    A device for longitudinal feeding of logs into a sawing machine is known, comprising guides arranged parallel to each other in the same horizontal plane, on the inner and outer side of which the inner and outer drive carriages with rotary gripping levers, whose pivot axes are mounted on one of the carts are located vertically
    However, the absence of lateral displacement of the levers that have already captured the log, in order to orient the longitudinal axis of the log in the required direction, does not allow the sawing process to be carried out effectively with maximum wood yield and high productivity.
    The purpose of the invention is to increase productivity.
    The goal is achieved by the fact that the axes of rotation of the gripping levers on the other trolley are also arranged vertically, and each trolley is equipped with a transverse orientation device of the log, while the transverse orientation device is made in the form of having the same length of additional levers rigidly connected to the gripping levers in opposite directions the sides with respect to the direction of supply of the log and associated with the power cylinder.
    FIG. 1 shows the installation, a general view in the direction of supply of the log; in fig. 2 shows a device for longitudinal feeding of a log and a pre-orientation mechanism, top view; in fig. 3 - longitudinal feed device, side view; in fig. four -. the same, top view; in fig. 5 - the same. in a larger scale.
    The proposed device for longitudinal feeding of logs is used in an installation whose operation comprises the following main steps: 1 — log transfer, 2 — measurement and pre-orientation, 3 — transfer of the log to the longitudinal feed mechanism, and 4 — longitudinal feed of the log 5 to the sawing mill (or another ) machine 6. The longitudinal feed is carried out by the device 7, but first
    using the device 8, the size and shape of the processed logs is measured, and they are pre-oriented for subsequent rational cutting and obtaining the maximum lumber yield. In this position, the logs 5 are transmitted further by the transmitting mechanism 9 to align the log axis in the position of rational cutting with the longitudinal axis of the longitudinal feed device 7.
    The device 8 includes a series of retaining elements 10, each of which consists of a pair of chain levers 11 and 12, forming a V-shaped groove for keeping the log from turning. In this case, there are four of these elements, but two elements can also perform their function, located at the ends of the log, and the other two will be in the off position. Each of the chain levers I1 and 12 consists of a continuous chain (tape) 13, meshed with freely set sprockets 14. Rotation of the log can be carried out manually using a tong-shaped gripper 15 (Fig. 4), and chain levers} 1 and 12 assistance of the power cylinder 16 (Fig. 2), which sets them either to the working or non-working. (horizontal) position. Each power cylinder 16 is connected to the pump 17 through a corresponding control valve 18, which can be controlled both manually and in automatic mode. The connector 19 of the device, transmitting the movement from the power cylinders 16 to the chain levers P and 12, can be of any known design .
    The transmission mechanism 9 includes a device 20, extending in the feed direction of the log (FIG. 2), which has the ability to move in a horizontal plane in the direction perpendicular to its length, along the rails 21 using upper and lower rollers 22 and 23 and a double-acting actuator 24 located between the carrier device 20 and the fixed part of the machine frame. The energy source for the actuator 24 can be a pump 17 connected via control valve 25,
    The clamping of the log 5 on the carrier device 20 is carried out with the help of several gripping pairs of the stem; 26, which are me-1; with the retaining elements 10 of the measuring device 8. FIG. 2 shows only two pairs of claws out of four. Each pair of claws 26 has the option of independently raising or lowering relative to the carrier 20, for which it is mounted on a lifting frame 27 located on the carrier 20 with four vertical directions of the posts 28 and rollers. Each frame 27 is raised or lowered by means of an actuator 29 located between the frame and a non-responsive device and connected to a pump 17 via a control valve 30. Each pair of claws consists of levers hinged to the frame by axes 31 and 32. Between free ends 33 of the levers, an actuator 34 is connected to the pump 17 by means of a control valve 35. To accommodate the rotational movement of the levers, their elements 36 are connected by a pull 37. When the actuator 34 is fully compressed, the claw levers 26 olagayuts almost horizontally permitting them at lowered frame 27 and moving the carrier device 20 to the retaining elements 10 to pass under a log. After each frame 27 is lifted by the actuator 29, clamping the log with the claw levers 26 for diluting the chain levers 11 and 12 to the horizontal position, the log 5 is brought out by the actuator 24 on the support device 20 to the zone of operation of the device 7 in dp. The device 7 for longitudinal feeding of the log consists of an inner 38 and an outer 39 driven carriages, which move along I-beams 40, mounted on vertical stands 41 at a height slightly higher than the upper part of the sawing machine 6, and in close proximity to it. I-beams 40 form inner 42 and outer 43 guides arranged parallel to each other in the same horizontal plane, respectively for trolleys 38 and 39. Thus, trolleys 38 and 39 can pass through each other in both directions. Trolleys 38 and 39 have turning circles of vertical axes gripping levers 44 and 45, respectively, which are tilted downward and slightly forward in the feed direction of the log (FIG. 3). An external driving carriage 39 comes into the design. A rectangular frame 46 is horizontal, the width of which extends beyond the I-beams 40. A rectangular frame 46 is installed with a considerable excess relative to the beams 40 on the uprights 47 and 48, which in their lower part are connected by crossbars 49 These crossbars are located to the side of the outer guides 43 and have rollers 50 placed in the guides 43. The axles of the vertical axes 51 and 52 located to the side of the kmcich 43 and side axles are attached to the frame 46 and the crossbar 49 kanchivayuschihs below the level of the I-beams 40 (Fig. 1). The levers 53 are attached to the Lower end of each axis 51 and 52. When the axes 51 and 52 are simultaneously turned in opposite directions, the levers 53 either turn towards each other, or away from each other. Such rotation of the axes 51 and 52 can be communicated by means of levers 54 attached to the upper end of axes 51 and 52 and a double acting actuator 55, which is connected to the free ends of the levers 54 and can be controlled manually or automatically from the control valve 56 pump 57. The outer cart 39 has a device of transverse orientation of the levers 45, which is made in the form of additional levers 58 and 59 having the same length, rigidly connected through axles 51 and 52 with gripping levers 53 directed in opposite directions relative to log feed directions. The free ends of the additional levers 58 and 59 are interconnected by a power cylinder 60, which serves as an adjustable link. Power cylinder 60 is connected to pump 57 via a controlled valve 61, which can be controlled either manually or automatically. The control valve can operate, firstly, in a self-adjusting mode, in which the cylinder 60 is disconnected from the pump 57 and can therefore be freely compressed or decompressed depending on the force acting on it from the levers 58 and 59, secondly in a blocking mode in which the medium is compressed cannot flow freely through the power cylinder 60. In addition, the control valve 61 can operate in two other modes as well, allowing the power cylinder to communicate with the pump 57, in one of which the power cylinder 60 is pressed and in the other is compressed.
    In the event that the gripping arms 45 converge to grip the log 5 held by the transmission mechanism 9, the cylinder 60 can be in self-alignment mode, in which the levers 53 can deflect to any position that allows them to grab the log. After the log is trapped and held in place by the compressive force generated by the drive 55, the distance between the free ends of the levers 53 remains unchanged. Obviously, now the compression of the ram will cause the ends of the levers 53 to move in one of the lateral directions (downwards in Fig. 4), while decompression of the drive 60 will cause the ends of the levers to move in the opposite direction. When the arms with the log are set to the required position, the actuator 60 can be placed in blocking mode, in which the arms are kept from lateral displacement.
    The gripping levers 44 of the inner drive carriage 38 are driven and controlled by mechanisms substantially similar to those of the outer carriage 39.
    The only difference between them is that the levers 62 and 63, equipped with the same exciting elements, have the ability to deflect to the non-working position (shown in dotted lines in Fig. 3) almost under the bottom surface of I-beams 40, so that nosBoj aeT will pass through them levers 53 external carts.
    The inner drive carriage 38 includes a 1 × 5 horizontal rectangular frame 64, on the side members 65 of which rollers 66 are mounted, which are located in the inner guides 42. The side members 65 also have sub-liners in which the beam 67 is rotatably mounted around the axis, perpg. iDicultural direction of bronla
    Axes 68, corresponding to axles 51 and 52 of the outer m (tracks, are fixed in their trunnions on the transverse beam 67. Levers 62 and 63 are attached to the lower ends of the axes 68, which, when the beam 67 is rotated, either rise to the non operating position or lower to the working position. The beam is rotated by means of a double action actuator 69, one end of which is eccentrically connected to the beam 67 and the other connected to the frame 64, as shown in Fig. 5, the actuator 69 is connected to the pump 57 by means of a control valve 70 .
    The convergence and dilution of the levers 62 and 63 is carried out by means of a double action actuator 71, which is located between the free ends 72 and is connected with them. The drive 71 is controlled by a valve 73 located in the circuit of pump 57,
    The inner carriage 38, as well as externally, has a device of transverse orientation of the levers 44, which is designed as additional levers 74 and 75 rigidly connected to the gripping levers via axles 68 and directed in opposite directions in the feed direction. The free ends of the additional levers 74 and 75 are interconnected by a power cylinder 76. The control valve 77 is designed to control the pump 57, creating self-aligning and blocking modes, as well as modes in which the drive is compressed and decompressed.
    Although some of the structural parts of the inner carriage 38 protrude to a small height above the frame 64, “as can be seen from FIG. 3, the frame 46 of the outer sub-carriage of the cart 39 is held by its uprights at a sufficient height to allow the trolleys to freely pass through each other.
    The carts 38 and 39 move along their rails in both directions using reversible electric motors 78 and 79 installed at the end of the I-beams C The engine 78 drives the inner carriage 38 through the recht: torus 80 and drive axle 81, located across the direction logs ,. The axles 81 are transferred from the 7 torus 80 through the chain 82. Gears 83 are included at the opposite ends of the axle 81 and are inside the inside guides. At the front ends of the inner guides of the I-beams 40, gears 84 are installed, which are in line with the corresponding gears 83. A gear 85 is attached to the gears 83 and 84 on each side of the longitudinal feed mechanism, forming a closed loop, the lower part of which is attached to internal cart 38. The engine 79 leads the external cart 39 through a similar device, consisting of a gearbox 86, into (the axle 87, gears 88, located inside the outer guides of the gears 89 of the chain 90. The sawing machine 6 has an input t: strict The device 91, creating a flat bottom surface of the feed conveyor 92 and forming the lateral flat surfaces of the device 93, which can be made in the form of a series of vertical saws. The feed conveyor 92 includes a pressure roller 94 and parallel chains 95 worn on sprockets 96 and 97, which are located between the planer device 91 and the device 93. The jumble of chains 95 is the same as the trolleys 38 and 39. The pressure roller 94 under the action of the power cylinder 98 presses the log with its stripped surface to nveyeru 92, and the front end of a log enters the gap between the pair of feed rollers 99 which are mounted slightly in front device 93 and provide the desired direction and feeding in logs pa Rezai machine. The device works as follows. After the transfer of the I log, the measurement and the pre-orientation 2, the log transfer by the transmitting mechanism 9, the log is prepared for movement by the Longitudinal feeder. however, as soon as the log begins to move by mechanism 9 into the measuring device, a new log may already arrive. Suppose the carts 38 and 39 are in the positions shown in FIG. 3, i.e. The inner cart 38 holds the front end of the log, and the outer 39 holds the back end. The gripping levers 44 of the inner cart hold the log until the front end of the log approaches the feed rollers 99. At this point, the inner cart reaches its extreme position and the gripping levers release the log, the front end of which is guided and shifted by the feeding conveyor 92, and the rear one still with the help of the trolley 39. As soon as the gripping levers 44 release the log, they deflect to the non-operating position, after which the inner trolley 38 moves in the opposite direction inside and past the trolley 39 on its a place to grab the next log, which has already been delivered by the carrier device 20 by this time. The outer cart 39 continues to hold the back part of the log and move in the longitudinal direction until it reaches the limit position that coincides approximately with the position from which the inner rail began its movement in the opposite direction. In this position, its gripping arms 45 move to the sides and release the log. The cart 39 begins to move back, but not to its original position, but to the place of the cart 38 (Fig. 3). Thus, the waste time is relatively short, and the trolleys are reversed. It should be noted here that when each new log is fed, the carts alternate between each other. The present invention makes it possible to create in 1 a juice-efficient device for sequential feeding of logs to a sawing machine, which ensures a continuous supply of logs without delay and with an individual assessment of the size and shape of each log, thus achieving the highest productivity.
