様の問題があつた。 BACKGROUND ART In various wood industries that manufacture furniture, fittings, etc. or packaging materials such as wood chips, various types of lumber are subjected to processing such as cutting, grinding, polishing, etc., and wood chips and powder of various shapes are generated. Furthermore, in recent years, so-called decorative plywood has become widely used, and not only natural wood but also melamine resin,
Wood chips and scraps of surface-coated materials such as vinyl chloride and polyester are discharged, and because they involve synthetic resin materials, they are not easy to dispose of or incinerate. In addition, although such wood chips are lightweight, they are bulky and require a large amount of space to store.Furthermore, even when used as fuel, they have low thermal power and difficulty in igniting, making it difficult to dispose of them. On the other hand, similar problems have occurred with cutting waste from the processing of paper products, etc., and with general waste paper.

縮できる。 The end face of the insertion slider 60 defines a recess that forms the inner wall of the pressure cylinder 10 smoothly and seamlessly when the slider has completed insertion, at which time the insertion slider closes the hopper 68. Furthermore, as shown in the figure, by setting the height of the insertion slider 60 to the height equivalent to the inner diameter of the pressure cylinder 10, there is no variation in the cross-sectional area of the material insertion path by the insertion slider 60 from the hopper 68 to the pressure cylinder 10. No material adheres to the insertion slider 60, abrasion of the inner wall can be prevented, and smooth insertion and pre-compression can be performed.

切替える4ポート位置切替弁130を制御する。 The control circuit 120 has two differential amplifiers 124 and 128 connected in series and a variable resistor 126 connected to the conversion terminal of the differential amplifier 124, and the actuating hydraulic cylinder 16 operates the pressurizing piston in the pressurizing direction. The output terminal of the pressure filler 122 which outputs a signal corresponding to the pressure when the pressure is applied is connected to the non-conversion terminal of the differential amplifier 124. A reference signal corresponding to the compression pressure is set. In addition, this signal controls, via a differential amplifier 128, a four-port position switching valve 130 which switches the path of the pressure medium between the pressure conduit P to the hydraulic cylinder 44 and the return line R.

8から信号が入力される。 Assuming that the insertion slider 60 shown in FIG. 2 has completed insertion is the starting point, first, the control circuit 120
As a result, the insertion slider 60 returns until the signal from the output of the OR circuit 118 is output. At this time, the rear edge of the insertion slider 60 engages with the operating terminals of the limit switches 78-84, and the AND circuits 110-116 corresponding to each limit switch

れる。 When the limit switch is released again by the rear edge of the insertion cylinder 60, the AND circuit 98,
100 becomes conductive. At this time, as soon as it is detected that the pressure in the actuating hydraulic cylinder 74 for supplying a large amount of material is too high, a signal is output from the differential amplifier 92, and at the end of each pressurization cycle, a signal is output by the control circuit 120. The reset trigger circuit 104 is controlled and a pulse is generated at the subtraction terminal of the counter 106. Conversely, if the pressure in the actuating hydraulic cylinder 74 is less than the pressure required for the predetermined precompression, a signal is generated at the output of the differential amplifier 90 and a pulse is input to the increment terminal of the counter 106.

れる。 In order to make the preliminary compression of the pressurizing cylinder 10 uniform in the axial direction, when the state of the counter 106 becomes high, the AND circuits 110 to 1 connected to the limit switches 76 to 84 located on the right side are activated.
16 is controlled and conversely, when the state of the counter 106 becomes low, the AND circuit 1 connected to the limit switch 76 to 84 located on the left side
One of 10 to 116 is controlled. In this way, in the return stroke of the insertion slider 60, the pre-compression in the next insertion stroke is controlled to a predetermined pressure value depending on the actual density of the material at the lower end of the popper 68.

Therefore, the converter 108 may be replaced with a converter modified from the one described above.

ツトがクランプジヨー解放端より放出される。 When the insertion slider 60 is completely inserted, the control circuit 120 controls the servo valve 132 to advance the operating hydraulic cylinder 16, and the pressurizing piston 12 moves from the right side to the left side in FIG. The pressure on the right side of this hydraulic cylinder 16 is controlled by the variable resistor 126.
When the target value set by is reached, the control circuit 120
As a result, the pressure in the hydraulic cylinder 44 is released, the upper clamp jaw 38 is released from its braking, and the pressure piston 12 moves further to the left, causing the pressure cylinder 1 to move further to the left.
2, another briquette of a predetermined length is transferred between the clamp jaws 28 and 38, and the briquette ahead of the predetermined length is released from the open end of the clamp jaw.

対抗することが可能となる。 The basic configuration is the same as that described above, and a pocket hole 134 is bored in the upper part of the insertion slider 60, and a pin 136 is inserted into the pocket hole 134 by means of a spring bias controlled by an electromagnet 138 placed at the upper part near the insertion opening 58. It is configured to be engaged with and locked.
This electromagnet 138 is controlled by the operating hydraulic cylinder 1.
This is done by the control circuit 120 when the switch 6 switches again to the return stroke. This lock makes it possible to counteract large pressures acting on the insertion slider 60 without applying large pressures to the actuating hydraulic cylinder 74.

This flap 140 is formed so that its end surface slides into contact with an arcuate wall portion 144 so that it can be raised and lowered. Further, a cam plate 146 driven by an electric motor 150 is in contact with the hinge 143, and the cam plate 146 includes a cam portion with an unequal radius that can lower the flap 140 to a preset position, and a cam portion for inserting the flap 140 into the hinge 143. A peripheral edge is formed with a protrusion that can be raised into full alignment with the lower wall of chamber 56.
