  In the material transport and supply device 2 having the above-described configuration, the front end pair of the belt conveyor 21 among the multiple round bar materials M stocked in pairs in the material stock unit 20 is always the cylinder of the material carry-out device 28 in the reverse stop position. Located directly below. In the material carry-out device 28, the piston rod of the elevating cylinder 29 is extended, and the suction plate 29 'at the tip of the rod is lowered to the upper end surface of the pair of round bar materials M to be in pressure contact with each other. To do. In this state, when the piston rod of the elevating cylinder 29 is simultaneously contracted and lifted, the pair of round bar materials M are simultaneously drawn from the bucket 22 onto the conveyor and suspended.

  The material carry-out device 28 moves forward by the operation of the movable plate 28b in a state in which the round bar material M is suspended, and carries the round bar material M to the forward stop position on the reverse stop position of the transport table 26 and stops. . Since the support pot 26 ′ of the transport table 26 in the reverse stop position is located immediately below the pair of round bar materials M in the forward stop position, when the piston rod of the lift cylinder 29 is extended and lowered, the round The lower end portions of the bar material M are supported by being supported in support pots 26 'pots on the base plate. When air suction is released after the extension operation and the piston rod of the elevating cylinder 29 is reduced, the suction plate 29 'is separated and the pair of round bar materials M are held upright on the transport table by the pot.

  The transport table 26 transports the pair of round bar materials M to the forward stop position set immediately below the clamping member 33a by the operation of the linear guide rail 25. In the forward stop position, the round bar material M is carried upright between the opened clamping members 33a of the material clamping device 33.

  The material clamping device 33 grips both sides of the round bar material M by closing the clamping member 33a. After the clamping, the lifter 32 is lifted to the lift stop position where the transfer machine 47 of the upper transport unit 40 is stopped by the upward drive of the lift belt 35 by the motor 34. As a result, the pair of round bar materials M simultaneously escapes from the support pot 26 ′ of the transport table 26, moves to the lifter side, is transported to the ascending stop position, and faces the opening front of the material casing 48. Moreover, in the lower conveyance part 20, the conveyance stand 26 and the material carrying-out apparatus 28 return to the original backward stop position by the action | operation of a linear guide rail, and prepare for carrying out of the next round bar material.

  The lifter 32 at the ascending stop position is held at that position when the lift belt 35 is stopped. After the belt stops, the movable member 37 of the pedestal 36 moves forward from the lift shaft position toward the transport machine 47. The movement of the movable member 37 causes the material clamping device 33 together with the arm member 38 to move toward the material casing 48 while grasping the pair of round bar materials M, and as shown in FIGS. 6 and 7, the clamping member 33a becomes the round bar material. M enters the material casing 48 together with M. Since the end of the member is open in a state where both sides of the round bar material M are sandwiched, the forward movement is performed until the material presser 48 ′ enters between the ends of the member and comes into contact with the round bar material M.

  After the movement of the movable member 37 is stopped, when the clamping member 33a is slightly opened and the clamping is loosened, the inner surface of the material presser 48 'is positioned on the opening edge of the bottom portion 48a. Is released by its own weight, falls into the opening of the bottom portion 48a, and is supported in an upright state by the shutter plate 48b closing the opening and fits in the material casing 48.

  After the release of the round bar material M, the movable member 37 moves backward on the pedestal to the original lift shaft position by the operation of the linear guide rail 36b, and the clamping member 33a comes out of the material casing 48 in a semi-closed state. After the retreat stop, the lifter 32 is lowered to the position of the lower transport unit 24 by driving the lift belt 35, and the clamping member 33a is opened after the moving process or the lowering.

  After the reversing movement of the movable member 37, the transfer machine 47 moves on the traveling beam 45 to the beam end on the injection device together with the transfer pedestal 45 by the operation of the linear guide rail 45b, and is stored in a pair of material casings 48. The rod material M is transported to positions facing the pair of melting cylinders 14 (see FIG. 4).

  After the conveyance machine 47 is stopped, the traveling beam 45 travels forward on the support beam together with the travel base 44 by the operation of the drive belt 43 by the motor 42 of the support beam 41. As a result, the conveyor 47 at the beam end also moves toward the front melting cylinder 14. As shown in FIGS. 5 and 8, the traveling beam 45 travels forward on the material receiving member 17 in which the material casing 48 is positioned on the receiving device 16 of the melting tube 14 and the round bar material M is stationary. The pressing is performed until both the bottom portion 48a and the opening of the receiving port portion 16a are positioned.

  The pressing of the round bar material M is performed while compressing the spring member 53 between the support plate 49 and the base plate 51, and the round bar material M is applied to the material receiving member 17 and the material presser 48 'by the spring pressure. It is sandwiched and held vertically. Also, the impact received by the material receiving member 17 at the time of material contact is also buffered by the compression of the spring member 53. After the traveling beam 45 stops traveling, the receiving port portion 16a and the shutter plates 16b and 48b of the bottom portion 48a are opened, and the driving belt 43 of the support beam 41 moves the traveling beam 45 to the original rear position at a low speed. With the retraction, the pressing force due to the compression of the spring member 53 is removed, and the round bar material M is dropped and supplied from the opening of the bottom 48a to the melting cylinder 14 through the opening of the receiving port 16a by its own weight.

  The openings of the receiving port portion 16a and the bottom portion 48a are closed by closing the shutter plates 16b and 48b after the round bar material M is dropped and supplied, and the traveling beam 45 is returned to the original rear position. After the traveling beam 45 is stopped, the conveyor 47 is moved to the beam end on the lift shaft side facing the material clamping device 33 by the operation of the linear guide rail 45a and stopped to prepare for the transportation and supply of the next round bar material.

  The traveling beam 45 can travel forward in a range that the length of the support beam 41 installed in parallel with the injection apparatus 1 allows. Therefore, even if the position of the material dissolution holding tank 13 that moves forward and backward together with the injection device 1 is at the front position indicated by the chain line in FIG. 8, the material can be conveyed and supplied to the melting cylinder 14 arbitrarily. As a result, it is not necessary to stop the injection device 1 at a certain position to carry and feed the round bar material M, and it is not necessary to position the material casing 45 with respect to the receiving device 16 of the melting tube 14. Material supply can be performed automatically.
