Abstract

PURPOSE:To enable mechanical bagging operation without the help of human hands by a method wherein a chute means sets the diameter of a cylinder at a certain value and a fine adjustment is imparted to the diameter of the cylinder when a block body passes through the cylinder. CONSTITUTION:When a rubber bale B is transferred in a direction of arrow (a) by a transfer roller conveyor 31, its height is measured in three steps at a height detection unit 1. At a dimension measuring unit 20, its width and length are measured and if the measured values are within allowable ranges, the bale is transferred to an infeed roller conveyor 34 from the conveyor 31 and if not in the allowable ranges, it is carried in a direction of arrow (g) via delivery roller conveyor 33 and removed. A bag A having been transferred to feed roller conveyor 36 is brought to a position before an open and close chute 5 by a bag set device 60, while the bale B is pushed toward the chute 5 by a push device 41 so as to be put into the bag A. The height of an opening of the chute 5 is set depending on the thickness of the bale B detected at the unit 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for automatically bagging block bodies such as rubber bales.

As a device for automatically bagging regular-shaped blocks, for example, a device disclosed in Japanese Patent Publication No. 16233/1983 is disclosed. After opening the bag opening, the device is set vertically and , is a device for filling block bodies.

[Problem to be solved by the invention]

It is difficult for conventionally provided bagging devices to bag all irregularly deformed blocks in a good manner.

For example, a rubber veil (an object formed by press-molding granular rubber into a substantially rectangular parallelepiped shape) deforms to a certain extent during storage. The degree of deformation varies depending on the storage conditions; for example, if a plurality of rubber veils are stored in a pile, the lower rubber veil will be thinner and larger in width and length. In particular, it deforms significantly during the summer.

When attempting to automatically bag a group of objects whose individual shapes differ slightly due to such deformation using a conventional bagging device, the following problems occur.

(1) Since the opening of the bag is fixed and the length/width ratio cannot be changed to match the object, it is not possible to pack the object into a bag if the width or thickness of the object is too large. Furthermore, if the bag is forcibly packed, the bag may be torn or the object may be damaged.

(2) The folding mechanism at the bag opening assumes that a regular-sized item is stored in the bag, so if an irregularly-shaped item is stored, it may not be able to be folded properly, causing problems such as protrusion, etc. A problem occurs.

The present invention has been made in view of such circumstances, and aims to solve the above problems.

(1) Mechanism of the entire apparatus First, the overall mechanism of the apparatus according to the embodiment and its operation will be explained.

(1-1> Arrangement and operation order of each member FIG. 1 is a view from above of the arrangement of various members constituting the embodiment device.

The rubber bale B, which is conveyed from the upper left end in FIG. 1 in the direction of arrow a by the input roller conveyor 31, is first
The height detection unit 1 measures the height (thickness) in three stages.

Next, in dimension measurement 820, the width and length are measured in two steps, and if the dimensions are within the allowable range, the bra chain conveyor 32 for direction change is transferred from the carry-in roller conveyor 31 to the infeed roller conveyor 34. Transferred via. If the dimensions are outside the allowable range, the paper is transported from the carry-in roller conveyor 31 to the discharge roller conveyor 33 in the direction of arrow g, and then removed.

The rubber bale B conveyed in the direction indicated by the arrow by the infeed roller conveyor 34 is then transferred to the feed roller conveyor 36 via the V-belt conveyor 35 for direction change. The paper is conveyed in the direction of arrow C, reaches the roller 37, and is then stopped.

The rubber bale B waits on the roller 37 until the bag A is conveyed to the front position of the opening/closing chute 5 by the bag setting device 60 and clamped at the outlet of the opening/closing chute 5.

When the bag ^ is clamped as described above, the rubber bale B is then pushed into the opening/closing bag 5 by the pushing device 41 and stuffed into the bag A from the outlet of the opening/closing bag 5. Here, the height of the opening of the opening/closing shinito 5 (inner diameter of the inlet in the thickness direction) is set according to the thickness of the rubber veil B detected by the height detection section 1.

The rubber bales B stuffed into the bags A are then conveyed in the direction of arrow d by a thrust conveyor 38a whose mounting table is shaped like a screen plate (see Fig. 9), and set in the front position of the gusset folding device 7. be done. That is, when the bag is put into a bag and the rubber bale inside the bag is placed, the thrust conveyor 38a
The thrust conveyor 38b moves from the solid line position to the broken line position in the figure, thereby conveying the product as described above.

When the bag holder and the rubber bevel leaf in the bag A are set in the forward position as described above, the gusset folding device 7 is activated and the gusset expansion bars 72a, 72b (and 72c) are opened.

72d; see FIG. 9), and a gusset folding plate 71a,
71b etc., the opening to the bag is folded.

When the opening of the bag A is folded, the feeding device t8 moves in the direction of the gusset folding device 7, and the feeding device t8 moves toward the gusset folding device 7.
Two crimp Ffie84.86 (see Figure 14)
pinch the folded part of bag A from above and below and press it down. Simultaneously with the movement of the feeding device 8, the thrust conveyors 38a and 38b are moved in the direction opposite to the arrow d direction and the arrow e direction, and return to the solid line position in the figure. At this time, the bag A and the rubber bale B inside the bag A are transferred from the thrust conveyor 38a to the thrust conveyor 38b using the gap between the screen plate-shaped mounting tables of both conveyors.

In this state, the feeding device 3 and the thrust conveyor 38b
move in the direction of arrow f at the same speed. In this way, the bag
The rubber bean leaf in the bag A is conveyed to the conveyor 39 while the folded portion is sandwiched between two crimping arms 84 and 86.

The conveyor 39 is composed of a plurality of conveyor groups each arranged so as to be able to enter the gap between the screen plate-like mounting tables of the thrust conveyor 38b, and thereby the bag A on the thrust conveyor 38b and the bag The rubber bale B in ^ is transferred from the thrust conveyor 38b to the conveyor 39.

Also, at this time, the folding portion of the bag sandwiched between the two crimping arms 84 and 86 of the feeding device 8 is moved from between the crimping arms to between the two +anes 91 and 92 of the chain conveying device 90 (
(see Figure 16).

Thereafter, the bag ^ and the rubber bale B in the bag A are carried on the conveyor 3 with the folded part being sandwiched between the two chains 91 to 92M.

In the apparatus of this embodiment, bagging on the rubber bale day is performed as described above.

(1-2) Function and structure of each member Next, the function and general structure of each member of the embodiment device will be described in order.

Bulky height detection unit 1 Figures 4 and 5 show the height detection unit 1, and Figure 4 shows the height detection unit 1.
FIG. 5 is a side view seen from the payout roller conveyor 33 side, and FIG. 5 is a front view seen from the direction of the dashed arrow V in FIG. 1.

The height detection unit 1 measures the approximate thickness of the rubber bale B to be packed. That is, the rubber veil B having a rectangular parallelepiped shape
For example, 15 cm, 25 cm, etc.
Since the initial thickness is either CG+ or 35cm, the thickness is measured before bagging, and based on this, the height of the inlet of the opening/closing unit 5 (inner diameter in the thickness direction) is measured. ).

The height detection unit 1 is integrally attached to a support plate 14 that is connected upwardly from the side plate of the carry-in roller conveyor 31, and an arm that extends from the upper end of the support plate 14 to the left in FIG. a proximity switch plate 13, a lever 12 rotatably supported at its center by the support plate 14, and a measuring roller 11 rotatably supported at one end of the lever 12. The other end side is configured to operate one of three proximity switches arranged on the proximity switch plate 13 depending on the height of the measuring roller 11. In addition, the fourth
In the figure, 31C is a table attached to the side plate of the carry-in roller conveyor 31, and 15 is a conveyance guide wall of the carry-in roller conveyor 31.

In the above configuration, when the rubber bale 8 is conveyed from the left side in FIG. 5 by the carry-in roller conveyor 31 and reaches the position of the measuring roller 11, the measuring roller 11 is moved upward to the height of the upper surface of the rubber bale B. Being pushed up. As a result, the other end of the lever 12 is displaced downward in accordance with the thickness of the rubber veil, and one of the three proximity switches provided on the proximity switch plate 13 is actuated. For example, if the rubber veil B is initially formed to have a thickness of 25 cm, the proximity switch corresponding to the middle thickness among the three proximity switches is activated.

Further, the circuit including the three proximity switches is connected to a circuit that controls the operation of the opening/closing unit 5, and depending on which proximity switch is turned on, the inlet port of the opening/closing unit 5 is switched on. The height (inner diameter in the thickness direction) is controlled. For example, in the above case, the initial height of the inlet is the twin rotary cylinder 53e (see Figures 7 and 8).
is set to an intermediate height. The opening/closing unit 5 will be described in detail later.

Main dimension measuring section 20 FIGS. 2 and 3 show the dimension measuring section 20, FIG. 2 is a schematic diagram as seen from the payout roller conveyor 33 side in FIG.
The figure is a schematic diagram seen from above.

The dimension measuring section 20 determines whether the width and length of the rubber bale B to be packed are within an allowable range.

That is, the rubber veil B, which is initially formed into a rectangular parallelepiped shape, deforms to a certain extent during storage. The degree of deformation varies depending on storage conditions; for example, if a plurality of rubber veils are stored one on top of the other, the lower rubber veil will be thinner and larger in width and length. In particular, it deforms significantly during the summer. Second, prior to bagging, it is determined whether the rubber bale B has a shape that can be stored in the prepared bag to prevent the bag from tearing or the like.

The dimension measurement unit 20 includes air cylinders 28, 29 for detecting whether the width is within the permissible range, and air cylinders 26, 29 for detecting whether the length is within the permissible range.
27, and a photoelectric switch (not shown) for detecting that the rubber veil B has reached the dimension measurement position.

In the above configuration, when the rubber veil B reaches the dimension side positioning lid, the four air cylinders 26.27°28, 2.
9 descends as shown by arrow 1 and operates. At this time, if the radius or length of the rubber veil B is outside the predetermined allowable range, any one or more of the piston rod tips 26a, 27a, 28a, and 29a of the four air cylinders will be It quickly contacts the rubber veil B,
As a result, a limit switch (not shown) provided on the air cylinder is turned on. In the figure, arrows J and k indicate the direction of movement of the piston rod of each air cylinder.

The circuit including the four limit switches is connected to a circuit for controlling the operation of the dispensing roller conveyor 33 and the direction change plastic chain conveyor 732,
When any one limit switch is turned on,
The delivery roller conveyor 33 is operated, and the operation of the plastic chain conveyor 32 is prohibited. As a result, the rubber bale is transported in the direction of arrow g (FIG. 1) by the delivery roller conveyor 33, and then removed.

On the other hand, if none of the limit switches are turned on, the delivery roller conveyor 33 is stopped,
Moreover, the plastic chain conveyor 32 is operated at a predetermined timing. As a result, after the rubber bale B is transferred to the infeed roller conveyor 34, the rubber bale B is transferred in the direction of the arrow (the first
(Fig.), and further transferred to the inlet-ra conveyor 36 via the belt conveyor 35.

In the above, the plastic chain conveyor 32 is composed of a plurality of conveyor groups respectively arranged in the roller gaps of the carry-in roller conveyor 31, and raises the tail foil 32b in the direction of the arrow β to move the plastic chain conveyor 32. By positioning the conveyor surface above the roller surface of the carry-in roller conveyor 31, the rubber bale B can be transported to the left in FIG. Note that the V-belt conveyor 35mo described above for transferring the rubber bale B from the infeed roller conveyor 34 to the feed roller conveyor 36 is similarly configured.

Push-in Device 41 FIG. 6 is a schematic diagram of the push-in device 41 viewed from the direction of the broken line arrow v1 in FIG.

The pushing device 41 is usually a feed roller conveyor 36.
After the rubber bale B is stopped on the roller 37, the bag A is clamped at the outlet of the opening/closing unit 5 as shown in FIG. 17(iii). It descends as shown by arrow I, and then the push plate 41
This is a device that sends out the comb veil B in the direction of the arrow port and pushes the comb veil B into the inlet of the opening/closing chute 5. At this time, a stopper 42 is lowered and placed on standby at a predetermined position in front of the outlet of the opening/closing unit 5, as shown in FIG.

In the above, the conveyance of the rubber bale B onto the roller 37 is detected by a photoelectric switch (not shown).
In addition, the control circuit of the pushing device 41 controls the clamping to the bag.
Control circuit for opening/closing chute 5 and 91"! -/ )
Device 160 (Fig. 110, Fig. 114, Fig. 115
It can be detected by being connected to the control circuit (see figure).

Main opening/closing chute 5 Figures 7 and 8 show details of the opening/closing chute 5.
Figure 7 shows the operating sequence.

The opening/closing sheet 5 is configured in a cylindrical shape with a plurality of guide plates, and the rubber veil B stopped on the roller 37 is
It functions as a guiding member when pushing into the bag A by the pushing device 41.

The height of the opening/closing chute 5 on the inlet port (Fig. 17, left end) side (
l (inner diameter in the transverse direction) is adjusted by the twin rod cylinder 53e, which is a member of the opening/closing unit 5, so as to approximately correspond to the thickness of the comb veil B detected by the height detection section 1. do.

In addition, the outlet of the opening/closing chute 5 (III (Fig. 17)
The height (inner diameter in the thickness direction) of the right end (inner diameter in the thickness direction) is set to be sufficiently smaller than that on the inlet port side before the bag A is clamped, as shown in FIG. 17 (1).

In this state, the bag setting device 60 (see FIGS. 10, 14, and 15) operates to convey the bag to a position in front of the opening/closing unit 5, and then as shown in FIG. As shown in FIGS. 17(i)-(j), while gripping both sides of the opening side of the bag A with the grippers 61 of the set group [160],
The opening side of the bag A is placed over the outlet of the opening/closing chute 5.

Next, the opening/closing chute 5 operates to pull up the upper guide plate 51f and the outlet sides of the upper corner guide plates 51a and 51b, and the lower guide plate 511 and the lower corner guide plates 51C,

) −= (iii) Clamp the bag as shown. The degree of clamping, that is, the extent to which the outlet sides of the upper guide plate 51f and upper corner guide plates 51a, 51b are pulled upward, and the degree to which the outlet sides of the lower guide plate 511 and lower corner guide plates 51c, 51d are pulled downward. The extent to which it is lowered is
It can be controlled as appropriate depending on the thickness of the rubber veil B detected by the height detecting section 1 or the openable size of the bag A.

On the other hand, by clamping the bag A, the bag A is placed on the upper guide plate 51f, the upper corner guide plates 51a, 51b, and the lower guide plate 511 and the lower corner guide plates 51c, 5bl, respectively.
The force from is added. Therefore, the upper guide plate 51f, the upper corner guide plates 51a, 51b, and the lower guide plate 511
The lower corner guide plates 51c and 51d slide on their contact surfaces, as will be described later. As a result, the degree of opening of the opening/closing bag 5 on the outlet side is further finely adjusted to follow the opening of the bag A.

In this way, when the bag ^ is clamped to the opening/closing chute 5,
The pushing device 41 operates, and the rubber veil B opens and closes through the chute 5.
It passes through the inside and is stored in a bag. At this time as well, each of the guide plates 51f and 51a of the opening/closing chute 5.

51b, 51i, 51c, and 51d each perform the above-mentioned sliding movement in accordance with the passage of the rubber veil B. That is, fine adjustment is also performed when the rubber veil B passes.

The mechanism of the opening/closing unit 5 that achieves the above-mentioned effects will be described in detail later.
