The waste glass conveying apparatus which concerns on 1st embodiment of this invention is demonstrated.
A waste glass transport device 1 shown in FIG. 1 is a device for transporting waste glass G, and includes a vibration conveyor 2, a crushing roller 3, a stopper 4, a shooter 5, and a cooling water supply unit 6. The waste glass transport apparatus 1 is an embodiment of the waste glass transport apparatus according to the present invention.

  The vibration conveyor 2 is a device that displaces and transports the waste glass G in a predetermined direction by applying vibration to the waste glass G, and includes a trough part 11, a base member 12, a vibration part 13, and the like.

  The trough unit 11 is a member that constitutes a conveyance path of the waste glass G in the waste glass conveyance device 1, and includes a groove part M. The groove portion M is a portion surrounded by a flat inner bottom surface 11a constituted by a bottom plate and inner side surfaces 11b and 11b constituted by side plates. In the waste glass transport device 1, the waste glass G is transported along the groove M.

  In this description, an XYZ coordinate system as shown in FIGS. 1A, 1B, and 1C and FIG. The X axis is a horizontal axis and corresponds to the length direction of the groove M in the waste glass transport apparatus 1 and corresponds to the transport direction of the waste glass G. The Y axis is a horizontal axis and corresponds to the width direction of the groove M in the waste glass transport device 1 and is orthogonal to the X axis. The Z axis is a vertical axis, corresponds to the height direction of the groove M in the waste glass transport device 1, and is orthogonal to the X axis direction and the Y axis direction.

  And in the waste glass conveying apparatus 1, as shown in FIG. 2, the waste glass G is conveyed along the groove part M toward the X-axis direction. In the following, the side and the direction indicated by the arrow A in FIG. 2 are referred to as “the downstream side in the conveying direction” or simply “the front” of the waste glass G, and the opposite side and the direction of the arrow A are “ It is called “upstream side in the transport direction” or simply “rearward”.

  As shown in FIGS. 1A and 1B and FIG. 2, the rear side end of the groove M of the trough portion 11 is sealed by a side plate 11c. And the front side edge part of the groove part M is open | released, and the discharge port H which discharges | emits the waste glass G conveyed along the groove part M in the conveyance direction downstream is formed.

  The base member 12 is a member that serves as a base for supporting the trough portion 11, and is fixed to the floor. In the waste glass transport device 1, the trough portion 11 is disposed above the base member 12, and is supported by the base member 12 via spring members 14 and 14 that are elastic bodies. And the trough part 11 is comprised so that a displacement is possible in the range which the spring member 14 elastically deforms.

The spring member 14 is interposed between the trough portion 11 and the base member 12 in a posture in which the telescopic axis direction is tilted forward toward the downstream side in the transport direction of the waste glass G. The trough portion 11 is displaced obliquely upward in the forward direction when the spring member 14 is extended and displaced upward, and is displaced obliquely downward in the backward direction when the spring member 14 is shortened and displaced downward.
The waste glass G disposed on the groove portion M of the trough portion 11 is biased by displacement upward and obliquely upward of the trough portion 11, and is displaced along the groove portion M using the biased force as a driving force.

The vibration part 13 is a part for applying vibration to the trough part 11. The vibration unit 13 shown in the present embodiment includes a motor 13a, a cam 13b, a cam follower 13c, and the like.
The motor 13a is fixed to the base member 12 with the motor shaft oriented parallel to the Y axis, and a cam 13b is attached to the tip of the motor shaft. The cam follower 13 c is attached at a position where the cam follower 13 a comes into contact with the cam 13 b on the lower surface of the trough portion 11.

  The vibration unit 13 converts the rotational movement of the motor 13a into the reciprocating movement of the cam follower 13c by rotating the cam 13b by the operation of the motor 13a (rotation of the motor shaft) and applying displacement to the cam follower 13c contacting the cam 13b. Then, vibration is applied to the trough part 11. In addition, the structure of the vibration part 13 shown by this embodiment is an example, and the waste glass conveyance apparatus 1 can employ | adopt the various vibration parts which have another structure.

The crushing roller 3 is a member for rolling on the waste glass G present in the groove part M, and has a substantially cylindrical shape. The waste glass conveying device 1 pulverizes the cullet C sandwiched between the pulverizing roller 3 and the groove portion M by rolling the pulverizing roller 3 on the cullet C along the outer peripheral surface 3a.
The length of the crushing roller 3 in the cylinder axis direction is smaller than the inner dimension in the width direction of the groove part M, and can be arranged inside the groove part M in such a posture that the cylinder axis direction is parallel to the Y axis direction. That's it. In the waste glass transport apparatus 1, the crushing roller 3 can be rolled in the transport direction of the waste glass G by such a configuration.
The crushing roller 3 has only to have a cylindrical outer shape and can roll in a certain direction along the outer peripheral surface 3a, and may be solid or hollow.

  And the waste glass conveyance apparatus 1 conveys the cullet C to the downstream side in the conveyance direction by applying vibration to the trough part 11 by the vibration unit 13, and also moves the crushing roller 3 placed in the groove part M downstream in the conveyance direction. Roll to the side.

The stopper 4 is a member for restricting the displacement of the crushing roller 3 to the downstream side in the transport direction.
In the waste glass conveyance device 1, the stopper 4 is brought into contact with the peripheral side surface on the downstream side in the conveyance direction of the crushing roller 3 placed in the groove portion M. In the waste glass conveyance device 1, the stopper 4 regulates the displacement of the crushing roller 3 toward the downstream side in the conveyance direction.

In this embodiment, as shown in FIG. 1 and FIG. 3A, the stopper 4 is configured by a single bar-like member, and the inner side surfaces 11b and 11b facing each other are connected by the stopper 4 inside the groove portion M. In this manner, the stopper 4 is provided. However, the aspect of the stopper 4 in the waste glass conveying apparatus 1 is not limited to this.
The stopper 4 in the waste glass conveying apparatus 1 can be comprised by two rod-shaped members, for example, as shown to FIG. 3 (B). Specifically, the stopper 4 can be configured as a mode in which the inner side surfaces 11b and 11b are projected toward the inside of the groove M (the inner side surfaces 11b and 11b are not connected). Moreover, you may comprise the stopper 4 in the waste glass conveying apparatus 1 with a portal-shaped member as shown, for example in FIG.3 (C). Specifically, the stopper 4 may be configured so as to cross the rod-shaped member in the width direction of the groove M above the upper ends of the inner side surfaces 11b and 11b and below the upper end of the crushing roller 3. .
The stopper 4 is preferably provided in a form that is symmetrical with respect to the conveying direction of the waste glass G in the groove M, whereby the cylindrical axis direction of the crushing roller 3 is in the groove M with respect to the Y axis. Can be kept parallel. Thereby, the crushing roller 3 continues to roll without stagnation in the groove M.

  Moreover, in the waste glass conveying apparatus 1, you may provide with the rod-shaped member which comprises the stopper 4 in the up-down direction.

In the waste glass transport device 1, the crushing roller 3 locked by the stopper 4 is rolled while being held at a fixed position. As a result, the crushing roller 3 rotates at the fixed position.
That is, the waste glass conveying device 1 rotates the crushing roller 3 using the vibration unit 13 of the vibration conveyor 2 as a driving source without providing a separate driving source for rotating the crushing roller 3.

  If there is no stopper 4 in the waste glass transport device 1, the crushing roller 3 continues to roll downstream in the transport direction of the waste glass G, and is eventually discharged from the discharge port H of the groove M, and on the trough portion 11. Will fall off.

The waste glass transport device 1 is configured such that the crushing roller 3 stays on the groove portion M and rotates by the stopper 4 so that the waste glass G transported along the groove portion M is always once. It passes through the bottom and is discharged from the outlet H.
In the waste glass conveying apparatus 1, the waste glass G is reliably crushed by the crushing roller 3 with such a configuration.

The shooter 5 is a member constituting a path for supplying the waste glass G conveyed by the vibration conveyor 2 to the groove part M and a path for supplying the cooling water W for cooling the waste glass G to the groove part M. .
The cooling water supply unit 6 is means for supplying the cooling water W to the groove part M through the shooter 5.

Here, the conveyance situation of the waste glass G by the waste glass conveyance apparatus 1 is demonstrated.
In the waste glass conveying apparatus 1, the waste glass G is thrown into the upstream end side of the groove M by the shooter 5 as shown in FIG. 2. The waste glass G is, for example, surplus glass generated in a glass melting furnace (not shown) or the like, and is thrown into the groove portion M of the trough portion 11 while being in a molten state.

  In the waste glass transport device 1, the cooling water W is supplied to the groove M by the cooling water supply unit 6 via the shooter 5.

The molten waste glass G is solidified by contact with the cooling water W and becomes cullet C. The cullet C is a solidified waste glass G and is conveyed along the groove M while being vibrated on the vibration conveyor 2.
The cullet C immediately after generation is a large lump, and the lump cullet C is gradually crushed by the vibration of the trough part 11. In the state where the cullet C is crushed by the vibration of the trough part 11, the cullet C still has a large size that is not suitable for reuse.

  In the waste glass transport device 1, the cullet C existing in the groove M passes through the bottom of the crushing roller 3 that is rotating while being held in place by the stopper 4, and then is discharged from the discharge port H. The cullet C is pulverized to a size suitable for reuse when passing under the pulverizing roller 3.

  In the waste glass conveying device 1, the size of the cullet C after pulverization can be adjusted by changing the weight of the pulverizing roller 3 and the roller diameter.

  Such a waste glass conveyance device 1 can be easily realized by, for example, additionally installing a crushing roller 3 and a stopper 4 on an existing vibration conveyor 2.

That is, the waste glass conveying device 1 according to the embodiment of the present invention includes a trough portion 11 that constitutes the groove portion M into which the waste glass G is charged, and a cooling water supply that supplies the cooling water W to the groove portion M of the trough portion 11. A portion 6 and a vibrating portion 13 that vibrates the trough portion 11. The trough portion 11 is vibrated by the vibrating portion 13 and the waste glass G together with the cooling water W along the groove portion M of the trough portion 11. The oscillating conveyor 2 for conveying the cullet C is provided, and is placed in the groove part M of the trough part 11 so as to be able to roll in the conveying direction of the waste glass G in the groove part M by vibration of the trough part 11. The crushing roller 3 and a stopper 4 that restricts the rolling position of the crushing roller 3 to the downstream side in the conveying direction of the waste glass G at a predetermined position are provided.
According to such a configuration, the waste glass transport device 1 can pulverize the waste glass G (cullet C) while transporting it. Thereby, it is not necessary to separately provide a step of pulverizing the waste glass G, and the time and cost required for reusing the waste glass G can be reduced.

  In the waste glass conveying apparatus 1, as shown in FIG. 1 (A), the crushing roller 3 is constituted by a circular tube member having both ends in a cylindrical shape opened in the axial direction.

  When the crushing roller 3 is constituted by a hollow circular pipe member, the amount of elastic deformation of the crushing roller 3 in the roller radial direction can be increased, and the crushing roller 3 can roll in the groove portion M and be repelled at the same time. . When the crushing roller 3 bounces in the groove portion M, a period in which the crushing roller 3 is lifted from the inner bottom surface 11a of the groove portion M is formed, and the cullet C easily enters the crushing roller 3 during that period. When the crushing roller 3 bounces in the groove M, it is possible to further apply an impact force to the cullet C when the crushing roller 3 falls on the inner bottom surface 11a of the groove M. For this reason, in the waste glass conveying apparatus 1, by adding the impact force to the cullet C in addition to the weight of the pulverizing roller 3, the cullet C can be more reliably pulverized to a reusable size.

That is, in the waste glass conveying apparatus 1, the crushing roller 3 is constituted by a hollow member.
According to such a configuration, the pulverizing roller 3 can be rolled and simultaneously moved away from the groove M. Thereby, the waste glass G (cullet C) can be reliably crushed by the crushing roller 3.

  In the waste glass conveying apparatus 1, as shown in FIGS. 1 (A) and 3 (A), (B), and (C), the stopper 4 is made of round steel. The stopper 4 made of round steel has a smooth peripheral surface. For this reason, when the crushing roller 3 rotates while being in contact with the stopper 4, the rotation of the crushing roller 3 is not hindered by the stopper 4.

That is, in the waste glass transport apparatus 1, the stopper 4 is made of a cylindrical member, and extends in a groove M of the trough portion 11 in a direction orthogonal to the transport direction of the waste glass G in plan view.
According to such a configuration, the crushing roller 3 can be smoothly rotated at a predetermined position for crushing the waste glass G (cullet C). Thereby, the waste glass G can be efficiently pulverized by the pulverizing roller 3.

Can be crushed.

That is, in the waste glass transport device 21, the vibration conveyor 2 is provided with a glass weir portion 7 that stands upright from the inner bottom surface 11a constituting the groove portion M and temporarily dams up the waste glass G.
According to such a configuration, it is possible to prevent the waste glass G having a large size that has not been crushed yet from being discharged from the vibrating conveyor 2, and pulverize at a predetermined position where the waste glass G (cullet C) is deposited. The waste glass G can be efficiently pulverized by rotating the roller 3 and using the pulverizing roller 3.

Further, in the waste glass transport device 21, as shown in FIG. 5A, the glass weir 7 is disposed at a position higher than the position P at which the crushing roller 3 in contact with the stopper 4 contacts the inner bottom surface 11a of the groove M. It is provided on the downstream side in the conveyance direction of G. With such a configuration, the crushing roller 3 can be prevented from coming into contact with the glass weir 7, and the cullet C can be continuously crushed by the crushing roller 3.
Further, in the waste glass transport device 21, the glass weir portion 7 is provided on the upstream side in the transport direction of the waste glass G from the position of the most downstream portion Q on the outer peripheral surface 3 a of the crushing roller 3 in contact with the stopper 4. ing. With such a configuration, the cullet C can be prevented from staying in a place where it is not pulverized by the pulverizing roller 3, and the cullet C can be efficiently pulverized by the pulverizing roller 3.

That is, in the waste glass transport device 21, the glass weir portion 7 is upstream of the most downstream portion Q in the transport direction of the waste glass G on the outer peripheral surface 3a of the grinding roller 3 in contact with the stopper 4, and It is characterized by being arranged on the downstream side in the conveying direction of the waste glass G with respect to the contact position P of the outer peripheral surface 3a of the crushing roller 3 with the inner bottom surface 11a of the groove portion M.
According to such a configuration, the waste glass G can be efficiently pulverized by the pulverizing roller 3 rotating at a predetermined position.

Further, in the waste glass transport device 21, as shown in FIGS. 4B and 4C, the standing range of the glass dam 7 in the width direction of the groove M is smaller than the width of the groove M. The glass weir portion 7 is not continuous in the width direction of the groove portion M, and includes an opening 7a that is a portion where the weir member is not erected in the central portion in the width direction.
Of the cullet C dammed by the glass dam 7 and pulverized by the pulverizing roller 3, the finely pulverized cullet C is discharged downstream from the opening 7a without passing over the glass dam 7.
In other words, the waste glass transport device 21 is configured to quickly transport the cullet C finely pulverized to a reusable size by providing the glass dam 7 with the opening 7a.

  As shown in FIG. 5B, the opening 7a may be provided not only at the center in the width direction of the groove M but also at the end in the width direction of the groove M, and the opening 7a is provided at two places. You may divide and provide in the width direction both ends of the groove part M. FIG.
