Pittsfield, Mass, assignors to Jones Division of Beloit Corporation, Pittsfield, Mass., a corporation of Wisconsln Filed Sept. 27, 1965, Ser. No. 490,414 Claims. (Cl. 100-215) This invention relates to a paper pulp press and more particularly to a turntable baling press which is used for the baling of paper pulp or the like.

In the papermaking industry, fibrous pulp is produced from a wood stock and thereafter the pulp is used in the manufacture of paper. The quality of the paper manufactured is determined by the quality of pulp used. Therefore paper manufacturers which have the facilities to both manufacture the pulp of a desired quality and thereafter to use the pulp in the manufacture of paper are not concerned with the purchase of paper pulp to produce paper. However, some paper manufacturers do not have the facilities to produce their own pulp and therefore must rely on outside sources to supply the pulp of the desired quality necessary to make a certain type of paper.

Therefore, the manufacturer and suppliers of fibrous pulp have found it advantageous to package the pulp in such a manner as to facilitate handling and shipping thereof. It is therefore the primary object of this invention to provide a new and improved means for the packaging of fibrous pulp.

Another object of the invention is to provide an apparatus which will press the fiber pulp into bales which are more easily handled and shipped.

Another object of the present invention is to provide an automatic turntable baling press which is capable of baling paper pulp economically and in a minimum of time.

Yet another object of the present invention is to provide a baling press with a turntable configuration for carrying a plurality of rotatable work station so that pulp can be baled at each of the work stations.

A still further object of the present invention is to provide a turntable baling press wherein the major forces which are exerted during the baling operation of the pulp are maintained substantially in a single plane.

Yet another object of the present invention is to provide a baling press wherein the forces exerted on the pulp during the baling operation are not transmitted into the supporting floor of the press.

FIGURE 11 is a sectional view taken along the line XIXI of FIGURE 10.

Shown in FIGURE 1 is a turntable baling press constructed in accordance with the principles of this invention and is designated generally by reference numeral 10. The baling press 10 is designed to be carried on a supporting floor 11 at three positions indicated by

reference numerals

13, 14 and 15. The weight exerted by the baling press 10 is carried substantially by the floor 11 at the positions 13 and 15, while the position 14 is used to carry the weight of a relatively small portion of the baling press assembly. In the preferred embodiment, a pair of thick sole plates 16 and 17 are carried above the floor 11 by thick layers of

grout

18 and 19 respectively as seen in FIGURE 1. A pair of beam supports 20 and 21 are carried by the sole plates 16 and 17 respectively for supporting a lower stationary beam 23. The lower beam 23 is supported solely by the beam supports 20 and 21 and is not supported in the center at position 14. The detail construction of the lower beam 23 will be described in greater detail hereinbelow.

An upper beam 25 is carried directly over the lower beam 23 and in substantially the same plane therewith by a pair of standards 26 and 27. The detail construction of the upper beam will be described in greater detail hereinbelow.

A turntable 28 has four elongated receptacles of substantially square cross section, each for receiving a quantity of fibrous material to be compressed therein into a bale. As seen in FIGURE 1, the turntable 28 is positioned or indexed in one of four possible positions which by way of example, places a receptacle 29in a loading position, a receptacle 30 in a compressing position, and a receptacle 31 in a position so that the bale therein can be lifted and ejected from the press. A fourth receptacle 32 is not seen in FIGURE 1 but is located directly behind the receptacle 31. That is, the four receptacles 29-32 are carried by the turntable 28 in quadrature relation.

The top of the turntable 28 consists of a circumferential plate 33 which has a rectangular opening therein in alignment with the receptacles 29-32. The top 33 and the receptacles 29-32 of the turntable 28 are fixedly secured to one another and rotate about a common axis to index the turntable prior to each operation of the press 10. A hydraulically energized support 3 4 is carried by the standard 27 for engagement with an extended plate 35 which is prevented from flexing by a gusset 36. The support 34 and bracket 35 serve to prevent the turntable 28 from canting, in the plane of the drawing shown in FIGURE 1, during the baling operation. Also, a hy- 'draulic support 38, which is carried by the lower beam 23, has a piston 39 which engages substantially the entire bottom surface of the receptacle 29 to help support the turntable to prevent canting thereof when the receptacle 29 is being filled with a fibrous material.

By way of example, the receptacle 29 is filled via a loading chute 40 which is carried above the upper beam 25. The loading chute 40 has a pair of

inlets

43 and 44 which are preferably connected to a cyclone, not shown, which removes a substantial amount of air which might otherwise be trapped between the particles of the fibrous pulp and thereby decrease the volume of pulp supplied to the receptacle 29. The loading chute 40 has an access door 45 for cleaning and/or maintenance within the chute 40. The access door 45 may have two portions hinged on opposite sides and which are maintained closed by a pair of bars 46 and 47 fixedly held across the unhinged sides as seen in FIGURE 1.

Secured to the outside wall of the inlet 43 is a hydraulic cylinder 48, which has a piston rod 49 extending therefrom to engage a lever 50. Similarly, the inlet 44 has secured thereto a hydraulic cylinder 52, which has a piston rod 53 extending therefrom to engage a lever 54. The levers 50 and 54 are secured to torsion rods which extend into the

inlets

43 and 44 and engage control doors to control the passage of fibrous pulp through the loading chute 40. A better understanding of the construction and operation of the loading chute 4t] and the

inlets

43 and 44 will be had from a detail description herein below.

Shown in FIGURE 2, is a side elevational view of the bailing press which is shown in FIGURE 1. The receptacle 31 has an extended plate 57 which is held substantially rigid relative to the receptacle 31 by a gusset 58. Similarly, the receptacle 32 has an extended plate 59 which is held substantially rigid relative to the receptacle 32 by a gusset 60. A pair of hydraulically energized

supports

61 and 62 are arranged to engage the

extended plates

57 and 59 respectively when the turntable 28 is in one of four possible index positions, thereby preventing the turntable 28 from canting during the bailing operation. The

hydraulic cylinders

34, 38, 61 and 62 are deenergized when the turn table is indexed to each successive position so as to al low the turntable to rotate. The standard 27 is shown as being constructed from a pair of

columns

64 and 65. The

columns

64 and 65 are secured to one another by a plurality of

spacers

66, 67, 68, 69 and 79, which maintain the columns 64 and 65 a fixed distance apart, as seen in FIGURE 2. It will be understood that the standard 26 may be constructed in substantially the same manner as that of standard 27, as shown in FIGURE 2.

A hydraulically energized bale lifter 71 actuates a piston head 72 which raises the bale within the receptacle which is in the position over the bale lifter. After the bale has been lifted so that the bottom of the bale is even with the circumferential plate 33, a hydraulically energized ejector 73 is actuated to push the bale onto a work floor 74, where suitable means may be provided for the removal of the bale pulp.

Also seen in FIGURE 2 is a drive motor 75 which is connected to a gear reduction 76 which, in turn, engages a drive gear, not seen, to drivingly rotate the turntable 28 to successive different indexing positions during the operation of the bailing press 10.

As seen in FIGURES 1 and 2, the receptacles 29-32 are preferably fabricated from sheet metal to form the sides thereof having a plurality of stiffeners secured to the outside surface of the side walls to make the receptacles sufficiently rigid against bulging during the tamping and compressing operation. By way of example, as seen in FIG. 1, one surface of the receptacle 29 has a sheet metal side 79 which has a pair of L-shaped beams 86 and 81 extending along the lower portion of the receptacle 29. The lower portion of the receptacle 29 is therefor sufficiently reinforced against bulging during the filling and tampering operation of the bailing press 10. However, during the compressing operation, when the fibrous pulp is pressed tightly together to form a bale, the pulp is compressed in the upper portion of the receptacle by a large hydraulic piston 83. Therefore, the upper portion of the receptacles 29-32 are further reinforced to withstand the increased pressures of compressing the pulp. Furthermore, the metal plate 79a of the upper portion of the receptacle may be of greater thickness and provided with a plurality of vertically mounted beams or

stiifeners

85, 86, 87, and 88, and a pair of horizontally mounted

stiffeners

89 and 90. The extreme upper portion of the receptacles 29-32, located immediately beneath the circumferential plate 33, may be further reinforced by stiffener members such as indicated by

reference numerals

92, 93 and 94'. Therefore, when the receptacles 29-32 are in the position indicated by the receptacle 30, the fibrous pulp therein is compressed by the piston 33 between the action of the piston head and the lower portion of the upper beam 25, as will be described in greater detail hereinbelow.

Shown in FIGURE 3 is a sectional view of the bailing press as seen in FfGURE 1. A stationary shaft 95 passes through the center of the turntable 28 and is secured at the ends to the upper and

lower beams

25 and 23 respectively. A rotatable sleeve 96 is carried about the shaft 95 and is secured to the circumferential plate 33 by a cylindrical bracket 98. Each of the receptacles 29-32 is secured to the rotatable sleeve 96 by one or more gussets 99 which engage a cylindrical bracket 109 secured to the rotatable sleeve 96.

Also secured to the rotatable sleeve 96 is a gear 101, which is in driving engagement with the gear reduction 76 of FIGURE 2. A gear cover 102 is provided to substantially enclose the gear 191 thereby preventing pulp or other foreign material from interferring with the gear action.

The lower end of the shaft 95 is held secure by a nut 103, which, when in position, is bolted or otherwise secured to the lower beam 23. In a similar manner, the upper end of the shaft 95 is held in position by a nut 104 which, when in position, is secured to the upper beam 25.

When the drive motor 75 is energized to drive the gear 101 the rotatable sleeve 96 will cause the turntable 28 to rotate therewith so as to be positioned to one of a plurality of work positions. A stop plate 105 is actuated by a hydraulic cylinder 106 when the turntable is in one of the work positions. A notch 107 is provided in the circumferential plate 33 at each of the work positions so as to engage the stop plate 195 in such a manner as to precisely index the turntable 28 in the desired work position. That is, the stop plate 105 will engage a notch along the periphery of the circumferential plate 33 so as to align the receptacles 29-32 with the respective work positions during the filling and bailing of fibrous pulp.

As mentioned hereinabove, the

inlets

43 and 44 of the loading chute 40 are provided with hydraulically actuated doors 108 and 109 respectively. Fibrous pulp may pass through one or both of the

inlets

43 and 44 and fall into receptacle 29 immediately beneath the mouth of the chute 49. After a sufficient amount of fibrous pulp has fallen into the receptacle 29 a hydraulic cylinder 110 is actuated to cause the piston 111 to extend downwardly and tamp the fibrous material within the receptacle 29. After the piston 111 has been retracted from within the receptacle 29 additional fibrous pulp is added to the receptacle. Once again, after the receptacle is filled with the fibrous pulp the hydraulic cylinder 110 is actuated thereby extending the piston 111 downwardly and again tamping the fibrous pulp. This action, of filling the receptacle and thereafter tamping the material therein, is performed several times during each filling operation of a receptacle. It will be understood that suitable sequential means is provided for this function. During the filling and tamping operation, the turntable 28 is prevented from canting by the hydraulic cylinder 38 which positions the piston 39 immediately beneath the receptacle being filled. After the receptacle is filled, the turntable 28 is rotated at 90 thereby placing an empty receptacle beneath the loading chute 40.

A receptacle 31, which is already filled with fibrous pulp, is positioned over the hydraulic piston 83 during the compressing operation of the baling press 10. Therefore, while the receptacle beneath the loading chute 40 is being filled, the pulp within the receptacle over the hydraul c. piston 83 is being compressed. As the piston 83 is actuated upwardly it engages a movable end wall 113 which is slidably carried within the receptacle 31, as seen in FIG- URE 3. This action will cause the pulp within the receptacle 33 to be compressed between the movable end wall 113 and a stationary end wall 114 which is secured to the upper beam 25. The construction of the baling press 10 is such that all of the force exerted by the piston 83 during the compressing operation of the pulp is distributed between the standard 27, stationary shaft 95, and the portions of the upper and lower beams extending therebetween. That is, none of the compressing forces are transmitted to the supporting floor 11 for the press 10.

As seen in FIGURE 3, the preferred embodiment of the turntable 28 is axially shiftable upwardly and downwardly relative to the sleeve 96 by means of the

hydraulic cylinders

34, 38, 61 and 62 so as to place the top surface of the circumferential plate 33 in abutting relation with the lower surface of the upper beam 25 to substantially seal the upper openings of the receptacles 29-32 during the filling and baling operations. A female spline member 137 is secured to the turntable 28 by welding or other suitable means and is in slidable engagement with a male spline member 112, which is secured to the rotatable sleeve 96. Also secured to the turntable 28 is a bushing 122 which is made of bronze or other suitable material, and is axially shiftable relative to the sleeve 96. A collar assembly 123 is secured to the sleeve 96 and rotatable therewith for engagement with the lower surface of the bushing 122 to support substantially the entire weight of the turntable 28 when the

hydraulic cylinders

34, 38, 61 and 62 are deenergized as the turntable is indexed to each successive position. The lower surface of the upper beam 25 and the upper surface of the top 33 are separated to allow easy indexing of the turntable.

Therefore, during the sequential movement of the turntable 28, the turntable is rotatably indexed to a predetermined position whereupon the turntable is raised in abutting relation with the upper beam 25 during the filling and pressing operation.

Shown in FIGURE 4 is a top plan view of the baling press 10. As mentioned hereinabove, the circumferential plate 33 has four rectangular square openings therein which form the upper extremity of the receptacles 2932. The portion of the upper beam 25 extending between a loading chute 40 and the standard 27 is provided with a cover plate 115. Indexing notches 107a and 10712 are located at the periphery of the circumferential plate 33. A similar pair of indexing notches are located at the periphery of the circumferential plate 33 at 90 relative to the notches 107a and 1071).

Extending outwardly from the upper beam 25 are a pair of

guides

116 and 117 which are adjacent opposite the sides of the receptacle 33 for guiding the baled pulp when it is ejected from the press. The ejector 73 is provided with a pair of

hydraulic cylinders

118 and 119 which are disposed on opposite sides of the stationary shaft 95 and perpendicular to the upper beam 25. The piston heads 120 and 121 of the

hydraulic cylinders

118 and 119 are secured together to form a large piston area for pushing the baled pulp from the baling press onto the work floor 74, as mentioned hereinabove. Since the turntable 28 is symmetrical, the center of the bale located at the ejecting position is an alignment with the stationary shaft 95 passing through the center of the baling press Therefore, two hydraulic cylinders are used on either side of the stationary shaft 95 to exert uniform pressure on the bale. However, this is not to be construed in a limiting sense. One large hydraulic cylinder may be used to eject the bale.

As seen in FIGURE 10, the piston heads 120 and 121 are bolted together by

bolts

124 and 125. As seen in FIG- URE 11, the piston heads 126 and 121 are provided with

flanges

126 and 127 respectively which are welded thereto as shown in FIGURE 11. A resilient spacer 128 is placed between the

flanges

126 and 127 to compensate for slight relative movement between the piston heads 120 and 121.

Seen in FIGURES 5 and 6 is a detailed view showing the construction of the upper beam 25. The beam 25 is fabricated substantially by welding steel components in the configuration shown. The retainer nut 104 engages the top portion of the stationary shaft 95 and is secured to a plate 129 by a plurality of bolts 130. The plate 129 extends athwart the beam 25. As seen in FIGURE 6, a pair of apertures 131 and 132 are provided for receiving the piston rods of the

ejection cylinders

118 and 119 respectively. The stationary end wall 114 is secured to a reinforcing plate 137 and together extend athwart the lower portion of the beam 25.

A portion of the inside surface of the side plates of the beam 25 form the side walls of the lower portion of the loading chute and is designated by

reference numerals

133 and 134. Metal plates 135 and 136 are placed between the side portions of the beam 25 and are angled inwardly toward the bottom to form the mouth or outlet of the loading chute 40.

FIGURE 7 is a detailed view showing the construction of the lower beam 23. The beam 23 is fabricated substantially by welding steel components: in the configuration shown. The lower beam 23 is provided with upper and lower reinforcing

plates

139 and 140 respectively. A cover plate 141 is bolted to the reinforcing plate 139 and may provide sealing means for the large hydraulic piston 83. The reinforcing plate 139 and 1411) are provided to strengthen the lower beam between the stationary shaft 95 and the standard 27. The lower portion of the stationary shaft 95 is secured to the lower beam 23 by means of a nut 142 which threadingly engages the shaft 95 and is secured to the lower beam 23 by a pair of supports 143 and 144. It will be understood that one of the stresses exerted by the piston 83 during the compressing operation are transmitted to the supporting floor 11, but rather, these stresses are contained within the stationary shaft 95, the standard 27, and the portion of the upper and lower beams extending therebetween.

The stationary shaft 95 is provided with a recess portion 147 for receiving a bearing 148. A. flange 149 is secured to the rotatable sleeve 96 by.suitable means such as welding. The flange 149 is bolted to a rotable collar 150 which is journalled by the bearing 148. A retainer 152 is provided for retaining the bearing 148 in a predetermined position on the stationary shaft 95. Also carried by the shaft 95 is a thrust bearing 153 which is held in place by the nut 142. The nut 142 and the collar 150 are provided with mating annular lands and grooves indicated by reference numeral 155. The lands and grooves on the nut 142 remain stationary while the lands and grooves on the collar 150 rotate relative thereto as the turntable 28 rotates. A seal 156 is provided between the stationary (shaft 95 and the rotatable sleeve 96, which serves to maintain the sleeve 96 substantially concentric about the shaft 95.

A further understanding of the hydraulic cylinder 38 and the piston 39 can be had from FIGURE 7. The piston 39 is sufficiently large as to engage the bracket 160 and 161 at the bottom of the receptacle 29. As mentioned hereinabove, the hydraulic cylinder 38 and the piston 39 are actuated to aid in supporting the receptacle 29 during the filling and tapping operation. To prevent the hydraulic cylinder 38 and piston 39 from canting the turntable 28 and the hydraulic cylinder 34 is provided to support the opposite end of the turntable 28.

Seen in FIGURE 8 is a view showing the detailed construction of the ejector 73 which is carried by the upper beam 25. The hydraulic cylinder 119 has an extendible shaft 164 which passes through both end walls of the upper beam 25. A bushing 165 is provided in the end wall 166 for guiding the rod 164. Supporting

blocks

168 and 169 are carried by the guides 117 and 117' respectively and may be in slida'ble engagement with the circumferential plate 33 during rotation thereof.

Seen in FIGURE 9 i s a view showing the detailed construction of the bale lifter which is used for lifting the bale from the receptacle for ejection therefrom. The bale lifter 71 has an extendible rod 170 which, when actuated, raises the piston 72 into engagement with the movable end wall 113 for lifting the bale from the receptacle 31. The

bale lifter 71 and support 77 are constructed from welded steel components.

Therefore, the turntable baling press of our invention has provided means for loading a receptacle with fibrous pulp to be baled at one work station and then moving the receptacle to another work station where the pulp therein is compressed into a bale, and further moving the receptacle to still another work station whereby the bale is lifted and ejected from the receptacle. The automatic turntable baling press provides a turntable carrying four receptacles in quadrature relation and in substantial radial alignment about a common axis such that rotation and indexing of the turntable positions each of the receptacles in precise alignment With respective work stations. Furthermore, that automatic turntable baling press of my invention provides means for pressing fibrous material into bales without exerting the pressing forces into the supporting floor.

Although the embodiment shown is substantially of welded construction of metal components it is not to be construed in a limiting sense. It will be understood that variations and modifications may be effected without departing from the spirit \and scope of the novel concepts to this invention.
